ObjectiveTo investigate the mechanism of action of Jiedu Huayu granules in improving liver injury in mice with acute liver failure （ALF） by observing its effect on a mouse model of ALF after prophylactic administration， and to provide a basis for clinical medication. MethodsA total of 60 specific pathogen-free male C57BL/6J mice were divided into normal group， model group， Jiedu Huayu granules group （JDHY group）， and farnesoid X receptor （FXR） agonist （GW4064） group using a random number table， with 15 mice in each group. The model of ALF was induced by a single intraperitoneal injection of D-galactosamine combined with lipopolysaccharide. The mice in the JDHY group were given prophylactic administration of 0.3 g/mL drug solution of Jiedu Huayu granules by gavage for 3 days before modeling， those in the normal group and the model group were given 0.9% NaCl solution by gavage， and those in the GW4064 group were given intraperitoneal injection of GW4064 for 3 consecutive days before modeling. The mice were sacrificed after modeling， and serum and liver tissue samples were collected. A veterinary automatic biochemical analyzer was used to measure the serum levels of total bilirubin （TBil）， total bile acids （TBA）， gamma-glutamyl transferase （GGT）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） in mice from each group； HE staining was used to observe liver pathological changes； RT-PCR was used to measure the mRNA expression levels of FXR， fibroblast growth factor 15 （FGF15）， fibroblast growth factor receptor 4 （FGFR4）， small heterodimer partner （SHP）， and bile salt export pump （BSEP） in mice， and Western blot was used to measure the protein expression levels of FXR， FGF15， FGFR4， SHP， and BSEP. A one-way analysis of variance was used for comparison between groups， and the Dunett method was used for further comparison between two groups. ResultsCompared with the normal group， the model group had significant increases in the serum levels of TBil， ALT， AST， TBA， and GGT （all P<0.01）， and compared with the model group， the JDHY group and the GW4064 group had significant reductions in the serum levels of TBil， ALT， AST， TBA， and GGT （all P <0.01）. HE staining showed that compared with the model group， the JDHY group and the GW4064 group had milder pathological injury， a reduction in the area of hepatocyte necrosis， and alleviation of cellular swelling and edema. Compared with the normal group， the model group had significant reductions in the mRNA and protein expression levels of FXR， FGF15， FGFR4， SHP， and BSEP in liver tissue （all P <0.01）， and compared with the model group， the JDHY group and the GW4064 group had significant increases in the mRNA and protein expression levels of FXR， FGF15， FGFR4， SHP， and BSEP in liver tissue （all P <0.05）. ConclusionJiedu Huayu granules may alleviate liver injury in mice with ALF through the FXR/SHP axis.

ObjectiveTo explore the effect of virtual reality on upper limb function in stroke patients through diffusion tensor imaging (DTI). MethodsFrom September, 2021 to March, 2023, 80 stroke patients in the Fuzhou Second General Hospital were randomly divided into control group (n = 40) and experimental group (n = 40). Both groups received routine rehabilitation, while the experimental group received virtual reality training additionally, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Action Research Arm Test (ARAT) before treatment, after treatment and after four-week follow-up; and they were scaned with DTI to measure the fractional anisotropy (FA) and relative anisotropy (RA) of cerebral peduncle and posterior limb of inner capsule of the affected side before and after treatment. ResultsTwo cases dropped in each group. The FMA-UE and ARAT scores increased in both groups after treatment and follow-up (F > 2.790, P < 0.001), and increased more in the experimental group than in the control group (t > 2.297, P < 0.05). FA and RA in the posterior limb of inner capsule increased in both groups after treatment (t > 21.013, P < 0.001), and increased more in the experimental group (t > 2.006, P < 0.05). The d-value of FA of the posterior limb of internal capsule before and after treatment (ΔFA) was positively correlated with the d-value of FMA-UE score (r > 0.362, P < 0.05) in both groups, the ΔFA of the posterior limb of internal capsule was positively correlated with the d-value of ARAT score (r = 0.459, P < 0.01). ConclusionVirtual reality training can promote the recovery of upper limb function in stroke patients, which may associate with the conductivity of posterior limb of inner capsule.

Objective:To explore the mechanism by which Pien Tze Huang improves liver Kupffer cell damage induced by lipopolysaccharide (LPS) by regulating the expression of miR-155.Methods:LPS induced liver Kupffer cells to establish a cell injury model to simulate septic liver injury. RT-qPCR was used to detect the expression of miR-155 in damaged cells, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the inflammatory response and apoptosis of damaged cells. Then we treated LPS-induced Kupffer cells with Pien Tze Huang at different concentrations (0 mg/L, 5 mg/L, 10 mg/L and 15 mg/L), and detected the expression of miR-155 in the cells, the inflammatory response of the cells and Apoptosis rate. MiR-155 was silenced in the cell injury model, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the effect of miR-155 on inflammatory response and apoptosis of model cells. Overexpression of miR-155 in damaged cells treated with Pien Tze Huang was used to detect changes in cellular inflammatory response and apoptosis. Data are expressed in the form of mean ± standard deviation, and each group of data is analyzed using t test or one-way analysis of variance.Results:In the LPS-induced liver Kupffer cell injury model, the expression of miR-155 was significantly increased ( P<0.05), the expression levels of pro-inflammatory factors IL-6 and TNF-α were significantly increased, and the anti-inflammatory factor IL-10 was significantly increased. was inhibited ( P<0.05), and the cell apoptosis rate was significantly increased ( P<0.05). After Pien Tze Huang treatment, the expression of miR-155 in damaged liver cells was inhibited ( P<0.05), the levels of cellular inflammatory factors IL-6 and TNF-α were inhibited, and the expression of anti-inflammatory factor IL-10 was promoted ( P<0.05). Inhibit cell apoptosis ( P<0.05). Silencing miR-155 reduced the inflammatory response and apoptosis rate of cells ( P<0.05). Overexpression of miR-155 can reverse the effect of Pien Tze Huang on liver cell injury ( P<0.05). Conclusions:In the model of LPS-induced liver Kupffer cell injury, Pien Tze Huang can inhibite the inflammatory response and apoptosis of cells by inhibiting the expression of miR-155.

Objective:To evaluate the efficacy and safety of Qingxuan Zhike granules in improving cough symptoms and shortening the course of influenza (wind-heat invading lung) in children.Methods:In this multicenter, randomized, controlled clinical trial, a total of 240 outpatient influenza patients from 7 hospitals, including the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine, from April 2023 to December 2023 were collected.The subjects were randomly divided into the control group and the experimental group via SAS software using the block randomization method.The differences between two groups were compared with t test, corrected t test and χ2 test.Subjects in the control group were given Oseltamivir phosphate granules, orally, twice a day (weight ≤15 kg, 30 mg/time; weight >15-23 kg, 45 mg/time; weight >23-40 kg, 60 mg/time; weight >40 kg, 75 mg/time; age≥13 years, 75 mg/time).In addition to Oseltamivir phosphate granules, subjects in the experimental group were also given Qingxuan Zhike granules, orally, 3 times a day (1-3 years old, 1/2 bag each time; >3-6 years old, 3/4 bag each time; >6-14 years old, 1 bag each time).After 5 days of treatment, the medication was suspended for 2 days.The effect of cough, antipyretic effect, clinical recovery rate, clinical recovery time, Canadian Acute Respiratory Illness and Flu Scale (CARIFS) score, traditional Chinese medicine (TCM) syndrome effect, complication rate, and adverse reactions were evaluated between the two groups. Results:Finally, 232 cases were included in the study, including 115 cases in the experimental group and 117 cases in the control group.Before and after treatment, there were no significant difference in CARIFS cough score between the experimental group and the control group (all P>0.05).After treatment, the change in CARIFS cough score in the experimental group [(-1.00±0.91) scores]was significantly higher than that in the control group [(-0.75±0.98) scores] ( t=-1.995, P=0.047).After treatment, the change in TCM syndrome cough score in the experimental group [(-1.69±1.51) scores] was significantly higher than that in the control group [(-0.97±1.63) scores] ( t′=-0.035, P=0.001).The time of complete regression of fever in the experimental group [(44.82±22.72) h] was shorter than that in the control group [(51.35±27.07) h], and the difference between the two groups was statistically significant ( t=-1.966, P=0.050).The fever score showed that the area under the curve between the CARIFS symptom fever score and time in the experimental group was 4.40±2.42, while that in the control group was 5.12±2.44, and the difference between the two groups was statistically significant ( t=-2.252, P=0.025).The clinical recovery rate was 93.91%(108/115) in the experimental group and 92.31%(108/117) in the control group, and there was no significant difference between the two groups ( χ2=0.233, P>0.05).The clinical recovery time in the experimental group [(2.93±1.21) d] was shorter than that in the control group [(3.29±1.15) d], and the difference between the two groups was statistically significant ( t=-2.279, P=0.024).After treatment, there was a significant difference in TCM syndrome score variation between the experimental group [(-12.00±4.13) scores] and the control group [(-10.85±4.31) scores] ( t′=-2.067, P=0.040).No complication occurred in both groups, and there was no significant difference in the incidence of adverse events between the two groups ( χ2=1.299, P>0.05). Conclusions:Qingxuan Zhike granules combined with Oseltamivir phosphate can effectively improve the cough symptoms associated with influenza in children, shorten the time and course of fever, and improve the TCM syndrome score; thus, they are safe in clinical application.

Objective:To investigate the characteristics of early motor development in small for gestational age (SGA) infants at high risk of brain injury.Methods:This study retrospectively enrolled a total of 81 SGA infants and appropriate for gestational age (AGA) infants who were at high risk of brain injury and attended outpatient follow-up visits in Xi'an Children's Hospital from February to October 2022. Seventeen SGA infants (SGA group) and 24 AGA infants (AGA group) were assessed for motor development using the Test of Infant Motor Performance (TIMP) at 2-5 weeks of corrected age (CA) and 20 SGA infants (SGA group) and 20 AGA infants (AGA group) were assessed at 14-17 weeks of CA. Independent samples t-test, rank-sum test, and Chi-square test were used to compare the demographic characteristics, high-risk factors of brain injury, and TIMP scores between the two groups. Results:At 2-5 weeks and 14-17 weeks of CA, the birth weights of SGA group were both less than those of AGA group [(1 817.1±440.3) vs. (2 630.0±560.9) g, t=－4.98; (1 752.0±434.4) vs. (2 226.3±699.8) g, t=－2.58; both P<0.05], but there were no significant differences in gestational age at birth or high-risk factors of brain injury between the two groups (all P>0.05). (1) At 2-5 weeks of CA: SGA group had lower total TIMP score [(71.6±13.7) vs. (80.5±11.5) scores, t=－2.26, P=0.029], elicited item score [61.0 scores (41.0-85.0 scores) vs. 69.1 scores (49.0-96.0 scores), Z=－2.15, P=0.037], sitting position score [8.8 scores (3.0-19.0 scores) vs. 11.2 scores (5.0-22.0 scores), Z=－2.07, P=0.038], and prone position score [(9.8±3.1) vs. (12.3±3.1) scores, t=－2.19, P=0.034] when compared with AGA group. (2) At 14-17 weeks of CA: The standing position score of the SGA group was lower than that of the AGA group [6.5 scores (4.0-11.0 scores) vs. 7.7 scores (2.0-11.0 scores), Z=－2.05, P=0.040], but no statistical difference was observed in the total TIMP score or the scores of sitting, supine, prone, turning, and lateral positions between the two groups (all P>0.05). Conclusion:Early motor performance of SGA infants is inferior to AGA infants before five months of age, which is embodied in the poor head control at 2-5 weeks of CA that further affects the stability of standing posture in them at 14-17 weeks of CA.

Objective To investigate the application value of the global myocardial work parameters in the non-invasive pressure-strain loop (PSL) technology for early assessment of left ventricular systolic function in patients with chronic kidney disease (CKD). Methods A retrospective analysis was performed on 74 patients with normal left ventricular ejection fraction (LVEF) who were hospitalized in the Nephrology Department of Zhongshan Hospital (Xiamen Branch), Fudan University, from August 2021 to December 2021. Based on CKD stages, patients were divided into early group (CKD stages 1-3) and advanced group (CKD stages 4-5). Additionally, 30 healthy volunteers matched for age and gender were selected as the control group. General clinical data, routine left ventricular ultrasound indicators, myocardial strain, and global myocardial work parameters were collected and compared among the three groups. Correlation analysis and multiple linear regression were used to assess the influencing factors of myocardial work. Results There were no statistically significant differences in global work index (GWI) and global constructive work (GCW) among the three groups. Compared to the control group, both CKD groups showed significantly reduced global work efficiency (GWE), along with significantly increased global waste work (GWW, P＜0.05). The absolute value of global longitudinal strain (GLS) in the advanced CKD group (n＝42) was significantly lower than that in the early CKD group (n＝32; [﹣17.09±0.82]% vs [﹣18.33±0.90]%, P＜0.05), and GWE was also significantly lower (93.00%[90.00%, 95.00%] vs 96.00%[92.25%, 96.75%], P＜0.05), while GWW was significantly higher than that in the early CKD group (150.00 mmHg%[105.25 mmHg%, 215.00 mmHg%] vs 88.00 mmHg%[64.25 mmHg%, 144.50 mmHg%], P＜0.05). Correlation analysis showed that GWE was negatively correlated with the absolute value of GLS and peak strain dispersion (PSD; r＝﹣0.396, ﹣0.558, P＜0.05), GWW was positively correlated with absolute value of GLS, and PSD (r＝0.341, 0.610, P＜0.01). Multiple linear regression results indicated that PSD was an independent influencing factor for GWE (β＝﹣0.558, P＜0.001) and GWW (β＝0.538, P＜0.001). Conclusions The myocardial work parameters GWE and GWW in non-invasive left ventricular PSL technology can identify subclinical left ventricular systolic dysfunction in patients with CKD early and quantitatively.

Objective To investigate the clinical effect of different magnetic stimulation pelvic floor modes in the treatment of perimenopausal myofascial pelvic pain syndrome(MPSS).Methods A total of 60 perimenopausal women who were clinically diagnosed with MPSS in the hospital from May 2022 to May 2023 were selected as the research objects.They were divided into groups A,B and C by random number table method,with 20 cases in each group.All patients in the three groups were treated with pelvic floor myofascial manual release.Group A was given pelvic floor magnetic stimulation(alternating 10 Hz and 50 Hz),group B was given sacral nerve root magnetic stimulation(50 Hz),and group C was given pelvic floor magnetic stimu-lation combined with sacral nerve root magnetic stimulation at the same time.The three groups were treated twice a week for eight weeks.Visual analogue scale(VAS)was used to evaluate the degree of pelvic floor myofascial tenderness before and after treatment,and Glazer pelvic floor surface electromyography was used to evaluate pelvic floor muscle function.Results Compared with before treatment,the VAS scores of subjec-tive pain and pelvic floor myofascial tenderness in the three groups were decreased after treatment,and the differences were statistically significant(P<0.05).Compared with group A and group B,the VAS score of subjective pain and the VAS score of pelvic floor myofascial tenderness in group C were significantly decreased after treatment,and the differences were statistically significant(P<0.05).Compared with before treatment,the average amplitude and coefficient of variation(CV)of pre-rest potential and post-rest potential in the three groups were decreased after treatment,and the differences were statistically significant(P<0.05).Compared with before treatment,only the maximum amplitude of rapid contraction,the average amplitude of 10 s sustained contraction and 60 s sustained contraction and CV in group C were improved,and the differ-ences were statistically significant(P<0.05).Compared with group A and group B,the average amplitude and CV of pre-resting potential and post-resting potential in group C were decreased after treatment,the maxi-mum amplitude of rapid contraction and the average amplitude and CV of 10 s continuous contraction and 60 s persistent contraction were improved,and the differences were statistically significant(P<0.05).Conclusion Dif-ferent magnetic stimulation pelvic floor modes can effectively relieve pain and improve pelvic floor muscle strength in the treatment of perimenopausal MPSS,and the effect of pelvic floor magnetic stimulation com-bined with sacral nerve root magnetic stimulation is the best.

Objective:To assess the effect of mild intraventricular hemorrhage（IVH）on the early motor development of infants at high risk of brain injury,and to guide the intervention according to its characteristics.Methods:A retrospective cohort study was conducted to select neonates discharged from the Neonatal Unit of Xi 'an Children 's Hospital from February 1，2022 to March 31，2023，with one or more high-risk factors of brain injury.The patients were assigned to low-grade IVH group and no IVH group according to ultrasound diagnosis.The research subjects exclucled other brain injury diseases besides mild IVH.Motor development was assessed using test of infant motor performance(TIMP)，reflecting performance in head control，auditory and visual responses，defensive movements，trunk movements，limb movements，and more.Both groups completed TIMP assessment between discharge and 16 weeks of the corrected age(CA).The differences of TIMP scores between two groups were compared . Results:A total of 329 neonates at high risk for brain injury were recruited，including 98 cases with grade Ⅰ-Ⅱ IVH（low-grade IVH group）diagnosed through brain ultrasonography and 231 controls(no IVH group).The Z scores of TIMP in the low-grade IVH group were lower than that in no IVH group（-0.25 ±0.87 vs.0.03 ±0.71， P=0.015）.The risk factors of brain injury were matched for further comparison.At CA2-5 weeks，the scores in low-grade IVH group of TIMP total scores（74.10 ±12.28 vs.84.24 ±7.71），observation items（10.57 ±1.47 vs.11.24 ±1.29），elicitation（63.17 ±12.13 vs.73.00 ±7.36），sitting（9.14 ±2.90 vs.11.65 ±3.26），supine（22.07 ±4.73 vs.24.79 ±3.55），prone position（10.35 ±3.74 vs.12.82 ±3.15）and lateral position（4.00 ±2.85 vs.5.48 ±2.13）were significantly lower than those in no IVH group（ P<0.05）.At CA6-9 weeks，the scores in low-grade IVH group of sitting position（10.44 ±4.01 vs.12.96 ±3.02），supine position（24.04 ±4.60 vs.26.83 ±3.53），lateral position（4.83 ±2.53 vs.6.25 ±2.6）were significantly lower than those in no IVH group（ P<0.05）.At CA12-15 weeks，the low-grade IVH group showed significant differences in TIMP total score（104.00 ±12.98 vs.114.10 ±13.16），elicitation（92.00 ±12.64 vs.102.00 ±13.10），sitting（17.00 ±3.50 vs.19.13 ±3.55）and lateral position（7.35 ±2.14 vs.9.00 ±2.37）compared with those from no IVH group（ P<0.05）. Conclusion:Mild intraventricular hemorrhage affected the early motor development of high-risk infants with brain injury，mainly manifested as a lag in the ability of head control at CA2-5 weeks，and the trend continued until CA12-15 weeks.Early monitoring of motor ability and intervention of head control ability should be carried out in high-risk children with mild intraventricular hemorrhage.
