ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory, Qijia Rougan prescription, combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted, and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis (CHB-HF) who met the diagnosis and inclusion criteria were randomly assigned to an observation group (Qijia Rougan prescription + entecavir) and a control group (entecavir). The treatment duration was 24 weeks. Liver stiffness measurement (LSM), fibrosis-4 index (FIB-4), portal vein diameter, hepatitis B serology, biochemical indicators, hepatic fibrosis markers in serum [hyaluronic acid (HA), laminin (LN), procollagen Ⅲ peptide (PⅢP), and type Ⅳ collagen (Ⅳ-C)], and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis, with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment, the observation group showed a significant reduction in LSM and FIB-4 (P<0.01), as well as notable improvements in LN, Ⅳ-C, and various TCM syndrome scores (P<0.05, P<0.01). When compared to the control group after treatment, the observation group demonstrated significant improvements in LSM, FIB-4, and various TCM syndrome score indicators (P<0.05, P<0.01), indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment, the observation group had better improvement in regression of stages F2 and F3 (P<0.05). When compared to the control group after treatment, the observation group exhibited superior improvement in regression of stage F3 (P<0.05). No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone, the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3, which is a potential “interception” point of the “Zhu Ke Jiao” theory.

BackgroundPatients with colorectal cancer are frequently comorbid with depression, which severely affects the quality of life and treatment compliance, while compromising the efficacy of anticancer treament and prognosis. Current therapeutic strategies still have notable limitations, particularly the lack of systematic and targeted synergistic regimens that integrate oncological management and anti-depressive intervention. It is of great clinical significance to explore a safe and effective new comprehensive intervention protocol and clarify its underlying mechanism of action. ObjectiveTo explore the effectiveness and safety of Shugan Yunpi Decoction in alleviating depressive and anxiety symptoms in colorectal cancer patients with depressive disorder through the PI3K-AKT signaling pathway, in order to provide references for the comprehensive treatment of colorectal cancer and depressive disorder. MethodsThis study was a randomized controlled trial. A total of 106 patients admitted to the Baoding No.1 Hospital of traditional Chinese medicine from November 2023 to July 2025 were enrolled, who met the diagnostic criteria for the Chinese protocol of diagnosis and treatment of colorectal cancer (2023 edition) and the diagnostic criteria for depressive disorder as specified in the Chinese Classification and Diagnostic Criteria of Mental Disease, third edition (CCMD-3). Patients were divided into the study group and the control group using a random number table, with 53 cases in each group. The control group received conventional chemotherapy combined with traditional Chinese medicine five-element music therapy, while the study group received conventional chemotherapy combined with Shugan Yunpi Decoction therapy. Both groups were treated for 8 weeks. Depressive and anxiety symptoms were assessed using the Hamilton Depression Scale-17 item(HAMD-17) and Hamilton Anxiety Scale (HAMA), respectively. Western blot protein immunoblotting was used to detect the expression levels of PI3K, AKT, and pAKT. Real-time fluorescence quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression levels of PI3K mRNA and AKT mRNA. Adverse reactions were recorded using a self-designed adverse reaction record form. ResultsRepeated measures analysis of variance showed that the time effects (F=139.336, 234.747), group effects (F=43.900, 101.266), and time-group interaction effects (F=13.409, 43.216) for HAMD-17 and HAMA scores in both groups were statistically significant (P<0.01). After 4 and 8 weeks of treatment, the HAMD-17 and HAMA scores in both groups were lower than those before treatment, with statistically significant differences (P<0.05). HAMD-17 and HAMA scores in the study group were lower than those in the control group (P<0.05). The time effects (F=571.356, 309.266, 414.492), group effects (F=6.901, 26.361, 39.362), and time-group interaction effects (F=18.592, 19.266, 33.484) for the protein expression levels of PI3K, AKT, and pAKT in both groups were all statistically significant (P<0.01). After 8 weeks of treatment, the protein expression levels of PI3K and pAKT in the study group were lower than those in the control group, while the AKT protein expression level was higher than that in the control group(P<0.01). The time effects (F=338.555, 225.059), group effects (F=5.429, 9.726), and time-group interaction effects (F=12.953, 21.214) for PI3K mRNA and AKT mRNA expression levels in two groups were all statistically significant (P<0.01). After 8 weeks of treatment, the expression levels of PI3K mRNA and AKT mRNA in the study group were lower than those in the control group (P<0.05). The incidence of adverse reactions in the study group was lower than that in the control group (χ2=4.810, P<0.05). ConclusionShugan Yunpi Decoction may help to ameliorate depressive and anxiety symptoms in colorectal cancer patients with depressive disorder by regulating the PI3K-AKT signaling pathway, decreasing the levels of PI3K, pAKT, PI3K mRNA, and AKT mRNA, with a favorable safety profile.

Objective:To evaluate the role of tubulin tyrosin ligase like-6 (TTLL6)-mediated microtubule polyglutamylation and Spastin(a microtubule cleaving protein)-induced excessive microtubule cleavage in the developmental impairment of dendritic spines in neonatal mice following repeated sevoflurane anesthesia, by utilizing TTLL6 conditional knockout mice.Methods:Fifty SPF female TTLL6 brain tissue-specific knockout (TTLL6 CKO: Camk2-Cre + ; TTLL6 f/f) and fifty control (TTLL6 CON: TTLL6 f/f) mice with C57BL/6J background, aged 6 days old were selected.TTLL6 CKO mice were divided into TTLL6 CON control group and TTLL6 CON sevoflurane group, and TTLL6 CKO mice were divided into TTLL6 CKO control group and TTLL6 CKO sevoflurane group, with 25 mice in each group by random block method.Mice in the sevoflurane groups were exposed to 3% sevoflurane with 60% O 2 for 2 hours daily on postnatal days 6, 8, and 10.The mice in control groups received only 60% O 2 under the same condition.The polyGlu-Tubulin and postsynaptic density 95(PSD95) protein expression were detected using Western blot. The expressions of TTLL6, Spastin, and α-Tubulin were assessed via immunofluorescence.Golgi staining and electron microscopy were employed to observe the density of hippocampal dendritic spines and synaptic conditions. The Morris water maze test was used to evaluate spatial memory capabilities. Statistical analysis was performed using GraphPad Prism 8.0 software. Results:(1) Behavioral results showed significant time and group interactions among the four groups in terms of latency to find the platform ( F=8.22, P<0.001).Mice in the TTLL6 CON sevoflurane group had a significantly longer escape latency on days 3-7 compared with the TTLL6 CON control group (all P<0.05), while there was no significant difference between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group (all P>0.05). The number of platform crossings differed significantly among the four groups ( H=11.95, P=0.007).The TTLL6 CON sevoflurane group had significantly fewer crossing times than the TTLL6 CON control group ( P<0.05), but no significant difference was observed between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group ( P>0.05). (2) Golgi staining and electron microscopy results revealed significant differences in dendritic spine density and synapse number among the four groups( F=29.00, 41.94, both P<0.001). The dendritic spine density ((5.83±0.40)/10 μm) and the number of synapses ((3.67±0.58)/10 μm) in the TTLL6 CON sevoflurane group were both significantly lower than those in the TTLL6 CON control group ((12.87±1.70)/10 μm, (9.33±0.57)/10 μm)(both P<0.05). In contrast, there was no statistically significant difference between the TTLL6 CKO sevoflurane group and TTLL6 CKO control group (both P>0.05). (3) Immunofluorescence results showed significant differences in the percentage of TTLL6 and Spastin and α-Tubulin co-expressed positive cells in the CA3 region of the hippocampus among the four groups of mice ( F=215.20, 26.08, both P<0.001). The percentage of TTLL6 and Spastin and α-Tubulin co-expressed positive cells in the TTLL6 CON sevoflurane group ((16.75±1.81) %, (47.98±8.42) %) were significantly higher than those in the TTLL6 CON control group ((2.44±0.58) %, (20.07±4.54) %)(both P<0.05), while there was no statistically significant difference between the TTLL6 CKO sevoflurane group and TTLL6 CKO control group ( P>0.05). (4) Western blot results indicated significant differences in the expression of polyGlu-Tubulin and PSD95 proteins in the hippocampal tissue among the four groups of mice ( F=19.66, 8.57, both P<0.001). The TTLL6 CON sevoflurane group had higher polyGlu-Tubulin expression (0.86±0.19) and lower PSD95 expression (0.61±0.13) compared to the TTLL6 CON control group (0.51±0.11, 1.01±0.07) (both P<0.05).However, there was no significant difference between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group ( P>0.05). Conclusion:The mechanism underlying long-term cognitive impairment in developing brain of neonatal mice caused by repeated sevoflurane anesthesia may relate to the upregulation of TTLL6-induced microtubule polyglutamylation and accelerated Spastin-mediated microtubule severing, which ultimately leads to abnormal dendritic spine development.

Objective:To investigate the effects of multimodal and multisensory stimulation training on feeding-swallowing and neurological functions in stroke patients with dysphagia.Methods:Stroke patients with dysphagia treated at Henan Provincial People's Hospital from January 2023 to October 2024 were enrolled. Patients were randomly divided into three groups according to the random number table method, with 36 patients in each group. These three groups underwent different interventions for a period of 8 weeks: multisensory stimulation intervention (stimulation group), multimodal rehabilitation training intervention (rehabilitation group), and innovative multimodal and multisensory stimulation training intervention (combined group). The Kubota water swallow test and functional oral intake scale (FOIS) were used to assess the effective improvement rate of feeding function. Differences in scores of modified Mann assessment of swallowing (MMASA), swallowing quality of life (SWAL-QOL), and National Institute of Health Stroke scale (NIHSS) among the three groups were compared before intervention, and at 4 and 8 weeks post-intervention. SPSS 27.0 software was used to analyze the data by one-way ANOVA, repeated measures ANOVA, Kruskal-Wallis H test, Mann-Whitney U test and Pearson correlation analysis. Results:(1) After 8 weeks of intervention, the effective improvement rates of feeding function were 75.00%(27/36) and 72.22%(26/36) in the stimulation group and rehabilitation group, respectively, which were both lower than that in the combined group (94.44%(34/36), both P<0.05). (2) The interaction effect between time and group was significant in MMASA scores among the three groups before and after intervention ( F=2.569, P<0.05). MMASA scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, MMASA scores in the combined group (85.64±11.26, 92.56±10.55) were higher than those in the stimulation group (73.52±12.65, 82.97±12.84) and rehabilitation group (72.47±11.38, 84.39±12.29) (all P<0.05). (3) The interaction effect between time and group was significant in SWAL-QOL total scores among the three groups before and after intervention ( F=18.561, P<0.05). SWAL-QOL total scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups ( P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, SWAL-QOL total scores in the combined group (115.64±9.26, 135.68±9.55) were higher than those in the stimulation group (108.42±8.65, 113.75±8.84) and rehabilitation group (108.37±8.38, 114.39±9.29) (all P<0.05). (4) The interaction effect between time and group was significant in NIHSS scores among the three groups before and after intervention ( F=7.890, P<0.05). NIHSS scores at 8 weeks post-intervention were lower than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also lower than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, NIHSS scores in the combined group (8.36±1.35, 5.22±1.05) were lower than those in the stimulation group (11.65±2.11, 8.78±1.12) and rehabilitation group (11.32±2.03, 8.36±1.17) (all P<0.05). Conclusion:Multimodal and multisensory stimulation training can improve feeding-swallowing function and neurological impairment in stroke patients with dysphagia, with intervention effects superior to those of either approach used alone.

Objective This study aimed to investigate the regulatory effect of electroacupuncture(EA)intervention on the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/hypoxia-inducible factor 1α(HIF-1α)signaling pathway in the hippocampal tissue of Alzheimer's disease(AD)model mice and its effect on astrocytic glycolytic function,further exploring how EA ameliorates AD-related cognitive impairment.Methods Eighteen APP/PS1 mice were randomly divided into model,EA,and sham EA groups(n=6)using the random number table method.Six wild-type C57BL/6J mice served as the control group.The EA group received EA stimulation at acupoints"Shenshu"(BL23),"Baihui"(GV20),and"Zusanli"(ST36)(administered every other day,20 min per session,for 4 weeks).The sham EA group received identical needle insertions at the same acupoints without electrical stimulation.The control and model groups were only restrained.Cognitive function was assessed using the Morris water maze and Y-maze spontaneous alternation tests.Hippocampal morphology was observed via hematoxylin and eosin staining.Hippocampal β-amyloid peptide 1-42(Aβ1-42)deposition was detected using immunohistochemistry.HIF-1α protein expression,the p-Akt/Akt,and p-mTOR/mTOR ratios were measured using Western blotting.Pyruvate kinase M2(PKM2)and lactate dehydrogenase A(LDHA)activities were quantified using enzyme-linked immunosorbent assay.Hexokinase(HK)activity and L-lactate content were determined using a colorimetric assay.Co-localization of LDHA with the astrocyte marker glial fibrillary acidic protein was quantitatively analyzed using immunofluorescence double-labeling combined with Pearson's correlation coefficient.Results Compared with the control group,the model group mice exhibited cognitive decline,as shown by prolonged escape latency(P<0.01),reduced number of platform crossings,lower time spent in the target quadrant,and decreased spontaneous alternation accuracy(P<0.01).The hippocampal neurons showed cell body swelling,deeper nuclear staining,enlarged intercellular spaces,and increased average optical density of Aβ1-42(P<0.01).The p-Akt/Akt and p-mTOR/mTOR ratios,as well as HIF-1α protein expression,were elevated(P<0.01).PKM2,LDHA,HK,and L-lactic acid levels were significantly increased(P<0.01),and the co-localization coefficient of LDHA with astrocytes was enhanced.Compared to the model group,the EA group of mice showed improved cognitive function.The hippocampal neurons had more intact structures,with a more uniform cell distribution.The average optical density of Aβ1-42 decreased(P<0.01),and the p-Akt/Akt and p-mTOR/mTOR ratios,as well as HIF-1α protein expression,decreased(P<0.01).PKM2,LDHA,HK,and L-lactic acid levels decreased(P<0.05),and the co-localization coefficient of LDHA with astrocytes significantly decreased(P<0.01).No significant improvement was observed in any of the indicators in the sham EA group compared with the EA group.Conclusion EA at"Shenshu"(BL23),"Baihui"(GV20),and"Zusanli"(ST36)ameliorates cognitive dysfunction in AD model mice.The underlying mechanism may involve suppressing the overactivation of the hippocampal Akt/mTOR/HIF-1α signaling pathway,thereby downregulating key glycolytic enzyme activities and reducing abnormal lactate accumulation.Furthermore,the astrocytic glycolytic metabolic pathway may constitute a key therapeutic target for this intervention.

Objective:To investigate the clinical value of continuous Bougie tube use in symmetrical three-port laparoscopic sleeve gastrectomy (LSG).Methods:The retrospective cohort study was conducted. The clinical data of 105 patients who underwent symmetrical three-port LSG at The First Hospital of Shanxi Medical University from October 2021 to October 2024 were collected. There were 57 males and 48 females, aged 27(range, 19-59)years. Of the 105 patients, 52 cases with continuous Bougie tube use during the surgery were divided into continuous group, while 53 cases with intermittent Bougie tube use were divided into intermittent group. Observation indicators: (1) surgical situations; (2) complications. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1) Surgical situations. All 105 patients underwent symmetrical three-port LSG. The operation time was (57±4)minutes versus (76±4)minutes for the continuous group and the intermittent group, volume of intraoperative blood loss was (26±6)mL versus (59±9)mL, time to first out-of-bed activities was (218±8)minutes versus (299±9)minutes, time to first anal exhaust was (19.6±2.9)hours versus (25.8±2.8)hours, visual analogue scale score for pain at 6 hours postoperatively was 2.3±1.0 versus 4.7±1.0, and duration of postoperative hospital stay was (1.5±0.6)days versus (3.1±0.9)days for the two groups, respectively. There were significant differences in the above indicators between the two groups( t=26.92, 22.31, 48.91, 11.15, 13.25, 10.21, P<0.05). (2) Complications. No severe postopera-tive complication occurred in any of the 105 patients. There were 26 cases and 38 cases with nausea and vomiting at 2 hours postoperatively, showing a significant difference between them ( χ2=5.19, P<0.05). Conclusion:Compared to intermittent Bougie tube use, continuous Bougie tube use during symmetrical three-port LSG can significantly shorten operation time and duration of postoperative hospital stay, reduce intraoperative bleeding and postoperative pain, accelerate recovery of patients, and lower the incidence of complications.

Objective:To study the diagnostic value and correlation of contrast-enhanced ultrasound time-intensity curve in the main pathological features of cervical cancer.Methods:From August 2021 to August 2023, 100 patients with cervical cancer and 100 patients with benign cervical tumors examined in Dingzhou People’s Hospital were selected for study. Patients with benign cervical tumors were included in the control group, and patients with cervical cancer were included in the observation group.The two groups of patients were examined by PHILIPS EPIQ7 C color Doppler ultrasound diagnostic instrument and PHILIPS EPIQ5 color Doppler ultrasound diagnostic instrument to obtain the quantitative parameters of the time-intensity curve of the two groups. The bivariate Spearman correlation test was used to analyze the main pathological features of cervical cancer patients (lesion diameter, pathological type, vascular invasion, lymph node metastasis, differentiation degree, clinical stage) and the correlation between radiotherapy and chemotherapy and the acquisition of time-intensity curve. The receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of the time-intensity curve.Results:The time to peak (TTP) value of the cervical cancer group was lower than that of the control group, and the peak intensity (PI) and maximum peak intensity ratio (PI/PIc) values were higher than those of the control group, the differences were statistically significant ( P<0.05). Compared with patients with non-squamous cell carcinoma, vascular invasion < 1/2, no lymph node metastasis, moderate to high differentiation, stage I-II, and after radiotherapy and chemotherapy, patients with squamous cell carcinoma, vascular invasion ≥ 1/2, lymph node metastasis, low differentiation, stage III-IV, and before radiotherapy and chemotherapy had lower TTP values, higher PI and PI/PIc values, and the differences were statistically significant ( P<0.05). Pathological type, vascular invasion, lymph node metastasis, differentiation degree and clinical stage were negatively correlated with TTP, and positively correlated with PI and PI/PIc ( P<0.05) .Chemoradiotherapy was positively correlated with TTP, and negatively correlated with PI and PI/PIc ( P<0.05). The sensitivity and specificity of combined detection of time intensity curve were higher than those of TTP, PI, PI/Ic, area under curve (AUCTC) and mean transit time (MTT), and the differences were statistically significant ( P<0.05). The AUC values of combined detection of TTP, PI, PI/PIc and time intensity curve were all > 0.85, and the diagnostic value was high. Conclusions:The time-intensity curve of contrast-enhanced ultrasound is closely related to the main pathological features of cervical cancer, such as pathological type, lymph node metastasis and staging. According to the changes, the effect of radiotherapy and chemotherapy can be judged, which can provide a good reference for the diagnosis and treatment of cervical cancer.

The number of platform crossings differed significantly among the four groups ( H=11.95, P=0.007).The TTLL6 CON sevoflurane group had significantly fewer crossing times than the TTLL6 CON control group ( P<0.05), but no significant difference was observed between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group ( P>0.05). (2) Golgi staining and electron microscopy results revealed significant differences in dendritic spine density and synapse number among the four groups( F=29.00, 41.94, both P<0.001). The dendritic spine density ((5.83±0.40)/10 μm) and the number of synapses ((3.67±0.58)/10 μm) in the TTLL6 CON sevoflurane group were both significantly lower than those in the TTLL6 CON control group ((12.87±1.70)/10 μm, (9.33±0.57)/10 μm)(both P<0.05). In contrast, there was no statistically significant difference between the TTLL6 CKO sevoflurane group and TTLL6 CKO control group (both P>0.05). (3) Immunofluorescence results showed significant differences in the percentage of TTLL6 and Spastin and α-Tubulin co-expressed positive cells in the CA3 region of the hippocampus among the four groups of mice ( F=215.20, 26.08, both P<0.001). The percentage of TTLL6 and Spastin and α-Tubulin co-expressed positive cells in the TTLL6 CON sevoflurane group ((16.75±1.81) %, (47.98±8.42) %) were significantly higher than those in the TTLL6 CON control group ((2.44±0.58) %, (20.07±4.54) %)(both P<0.05), while there was no statistically significant difference between the TTLL6 CKO sevoflurane group and TTLL6 CKO control group ( P>0.05). (4) Western blot results indicated significant differences in the expression of polyGlu-Tubulin and PSD95 proteins in the hippocampal tissue among the four groups of mice ( F=19.66, 8.57, both P<0.001). The TTLL6 CON sevoflurane group had higher polyGlu-Tubulin expression (0.86±0.19) and lower PSD95 expression (0.61±0.13) compared to the TTLL6 CON control group (0.51±0.11, 1.01±0.07) (both P<0.05).However, there was no significant difference between the TTLL6 CKO sevoflurane group and the TTLL6 CKO control group ( P>0.05). Conclusion:The mechanism underlying long-term cognitive impairment in developing brain of neonatal mice caused by repeated sevoflurane anesthesia may relate to the upregulation of TTLL6-induced microtubule polyglutamylation and accelerated Spastin-mediated microtubule severing, which ultimately leads to abnormal dendritic spine development.

Objective:To investigate the effects of multimodal and multisensory stimulation training on feeding-swallowing and neurological functions in stroke patients with dysphagia.Methods:Stroke patients with dysphagia treated at Henan Provincial People's Hospital from January 2023 to October 2024 were enrolled. Patients were randomly divided into three groups according to the random number table method, with 36 patients in each group. These three groups underwent different interventions for a period of 8 weeks: multisensory stimulation intervention (stimulation group), multimodal rehabilitation training intervention (rehabilitation group), and innovative multimodal and multisensory stimulation training intervention (combined group). The Kubota water swallow test and functional oral intake scale (FOIS) were used to assess the effective improvement rate of feeding function. Differences in scores of modified Mann assessment of swallowing (MMASA), swallowing quality of life (SWAL-QOL), and National Institute of Health Stroke scale (NIHSS) among the three groups were compared before intervention, and at 4 and 8 weeks post-intervention. SPSS 27.0 software was used to analyze the data by one-way ANOVA, repeated measures ANOVA, Kruskal-Wallis H test, Mann-Whitney U test and Pearson correlation analysis. Results:(1) After 8 weeks of intervention, the effective improvement rates of feeding function were 75.00%(27/36) and 72.22%(26/36) in the stimulation group and rehabilitation group, respectively, which were both lower than that in the combined group (94.44%(34/36), both P<0.05). (2) The interaction effect between time and group was significant in MMASA scores among the three groups before and after intervention ( F=2.569, P<0.05). MMASA scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, MMASA scores in the combined group (85.64±11.26, 92.56±10.55) were higher than those in the stimulation group (73.52±12.65, 82.97±12.84) and rehabilitation group (72.47±11.38, 84.39±12.29) (all P<0.05). (3) The interaction effect between time and group was significant in SWAL-QOL total scores among the three groups before and after intervention ( F=18.561, P<0.05). SWAL-QOL total scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups ( P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, SWAL-QOL total scores in the combined group (115.64±9.26, 135.68±9.55) were higher than those in the stimulation group (108.42±8.65, 113.75±8.84) and rehabilitation group (108.37±8.38, 114.39±9.29) (all P<0.05). (4) The interaction effect between time and group was significant in NIHSS scores among the three groups before and after intervention ( F=7.890, P<0.05). NIHSS scores at 8 weeks post-intervention were lower than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also lower than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, NIHSS scores in the combined group (8.36±1.35, 5.22±1.05) were lower than those in the stimulation group (11.65±2.11, 8.78±1.12) and rehabilitation group (11.32±2.03, 8.36±1.17) (all P<0.05). Conclusion:Multimodal and multisensory stimulation training can improve feeding-swallowing function and neurological impairment in stroke patients with dysphagia, with intervention effects superior to those of either approach used alone.

OBJECTIVE To investigate the therapeutic effect of Qingchang Huazhuo Formula(QCHZF)on mice with ulcerative colitis(UC)and the influences of fecal metabolites based on non-targeted metabolomics to investigate the mechanism of action of QCHZF in the treatment of UC.METHODS UC mice were induced by dextran sulfate sodium salt(DSS)and were administered with QCHZF.During the experiment,the body weight,stool characteristics and blood in stool were recorded daily,and the disease activity index(DAI)was calculated.At the end of the experiment,the length of colon was measured,colonic tissue damage in mice were ob-served by hematoxylin-eosin and alcian blue staining,mRNA expression levels of inflammatory factors,IL-6,IL-18 and IL-1β,and intestinal barrier factors,ZO-1 and Muc2,were detected in colon tissues via qPCR method,and protein expression level of intestinal barrier,Muc2,was detected with immunofluorescence.Fecal metabolite changes in mice were detected employing un-targeted metabo-lomics and analyzed by MetaboAnalyst 5.0 for metabolic pathway enrichment.RESULTS QCHZF significantly alleviated colitis symptoms,increased body weight,decreased DAI score,reversed colonic shortening,inhibited inflammatory factors expression,im-proved colonic tissue structure disorders,increased the number of goblet cells,and restored the intestinal barrier in UC mice,regulated 58 metabolites,mainly involving pathways of methionine and cysteine metabolism,purine metabolism,steroid hormone biosynthesis,vitamin B6 metabolism,tryptophan metabolism and primary bile acid pathways.CONCLUSION QCHZF can improve colitis symp-toms,repaire the intestinal barrier and modulate fecal metabolites and related metabolic pathways in UC mice.
