ObjectiveBased on transcriptomics， to explore the mechanism of Hei Xiaoyaosan regulating the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway to improve the learning and memory ability of insomnia rats with liver depression syndrome. MethodsSixty 8-week-old male SD rats were randomly divided into the blank group， model group， eszopiclone group （0.09 mg·kg^-1）， and low， medium， and high dose groups of Hei Xiaoyaosan （3.82， 7.65， 15.30 g·kg^-1）， with ten rats in each group. Except for the blank group， the other groups were induced insomnia rat model with liver depression by chronic restraint， tail clamping stimulation and intraperitoneal injection of p-chlorophenylalanine （PCPA）. Each treatment group received intragastric administration according to the specified dosage， once a day for 14 consecutive days. The pentobarbital sodium cooperative sleep test， open field test， and Morris water maze test were used to test the sleep quality， depressive-like behavior， and learning and memory abilities of rats. Additionally， enzyme-linked immunosorbent assay （ELISA） was used to detect the contents of 5-hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， brain-derived neurotrophic factor （BDNF）， glial cell line-derived neurotrophic factor （GDNF） and nitric oxide （NO） in hippocampus. Hematoxylin-eosin （HE） staining was performed to observe pathological changes of the hippocampal tissue， while terminal deoxynucleotidyl transferase deoxyuridine triphosphate （dUTP） nick end labeling （TUNEL） was used to evaluate apoptosis of hippocampal neurons. Transcriptomic sequencing technology was employed to identify differentially expressed genes in hippocampus between the model group and the blank group， as well as between the medium-dose group of Hei Xiaoyaosan and the model group. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis were performed on the intersecting genes. Subsequently， the enriched key genes and signaling pathways were analyzed and verified. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to assess the mRNA expression levels of phosphatase and tensin homolog （PTEN）， B-cell lymphoma-2 （Bcl-2）-like protein 11 （BCL2L11）， and mitogen-activated protein kinase 1 （MAPK1） in hippocampus， and Western blot was employed to evaluate the protein expressions of PI3K， phosphorylation （p）-PI3K， Akt， p-Akt， Bcl-2， Bcl-2-associated X protein （Bax）， and cleaved Caspase-3 in the same tissue. ResultsCompared with the blank group， the model group exhibited a reduction in body weight， an increase in sleep latency， and a decrease in sleep duration （P<0.01）. Additionally， rats showed obvious depression-like behavior， and their learning and memory abilities decreased. Furthermore， the contents of 5-HT， GABA， NO， BDNF and GDNF in hippocampus decreased （P<0.01）. Histological examination revealed a disorganized cell arrangement in the CA1 region of the hippocampus， characterized by irregular cell shapes， a reduced cell count， deeply stained and pyknotic nuclei， increased vacuolar degeneration， and an elevated apoptosis rate （P<0.01）. Compared with the model group， the body weight of the high and medium dose groups of Hei Xiaoyaosan increased， the sleep latency shortened and the sleep time prolonged （P<0.05， P<0.01）. Additionally， depression-like behavior and learning and memory abilities of rats were significantly improved， the levels of 5-HT， GABA， NO， BDNF and GDNF in the hippocampus increased （P<0.05， P<0.01）. These interventions also ameliorated pathological damage in the hippocampal CA1 area and reduced the apoptosis of hippocampal neurons （P<0.01）. Transcriptomic sequencing results indicated that Hei Xiaoyaosan might exert a therapeutic effect by regulating PI3K/Akt pathway through key mRNAs such as PTEN， BCL2L11， and MAPK1. The roles of these key mRNAs and proteins within PI3K/Akt pathway were further validated. In comparison to the blank group， the expression levels of PTEN， BCL2L11 and MAPK1 mRNA in the hippocampus of rats in the model group were increased （P<0.01）， while the protein expression levels of p-PI3K， p-Akt and Bcl-2 were decreased （P<0.01）， and the protein expression levels of PTEN， Bax and cleaved Caspase-3 were increased （P<0.01）. Compared with the model group， the high-dose and medium-dose groups of Hei Xiaoyaosan could down-regulate the expressions of PTEN， BCL2L11 and MAPK1 mRNAs （P<0.01）， up-regulate the expressions of p-PI3K， p-Akt and Bcl-2 proteins （P<0.01）， and down-regulate the protein expressions of PTEN， Bax and cleaved Caspase-3 （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan may regulate PI3K/Akt signaling pathway by down-regulating expressions of key genes such as PTEN， BCL2L11 and MAPK1， and thus improve the learning and memory abilities of insomnia rats with liver depression syndrome.

Objective: Exploring the effect and mechanism of Xinyang Tablet on reduction of ferroptosis in myocardial cells from mice with chronic heart failure. Methods: Sixty C57BL/6J mice were randomly assigned to the sham, model, Xinyang Tablet low-dose (0.34 g/kg), Xinyang Tablet medium-dose (0.68 g/kg), Xinyang Tablet high-dose (1.36 g/kg), and perindopril (0.607 mg/kg) groups using a random number table method (10 mice in each group). Except for the sham group, all other groups underwent aortic arch constriction surgery to construct a chronic heart failure model. On the third day after completion of the modeling, each treatment group was administered the corresponding medication by gavage, while the sham and model groups were administered equal volumes of water by gavage once a day for eight consecutive weeks. After treatment, cardiac ultrasound was used to detect the structure and function of the mouse heart. Hematoxylin and eosin staining was used to detect pathological changes in mouse heart tissue. Masson staining was used to detect the proportion of fibrotic area of mouse heart tissue. Realtime fluorescence PCR was used to detect the mRNA expression of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), collagen 3α (Col3α), and myosin heavy chain 7 (MYH7) in mouse myocardial tissue. Transmission electron microscope was used to detect the ultrastructure of myocardial cell mitochondria. Reactive oxygen species (ROS) staining was used to detect the mean fluorescence intensity of ROS in myocardial tissue. Micro-determination was used to detect superoxide dismutase (SOD) activity in myocardial tissue. An immunofluorescence assay was used to detect the mean fluorescence intensity of phosphorylated histone deacetylase 2 (p-HDAC2) in myocardial cell. Western blotting was used to detect the protein expression of nuclear factor-erythroid 2-related factor 2 (Nrf2), p-HDAC2, nicotinamide adenine dinucleotide phosphate oxidase 1 (NOX1), glutathione peroxidase 4 (GPX4), and cystine glutamate reverse transporter (xCT) in mouse myocardial tissue. Results: Compared to the sham group, the model group showed a decrease in left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), an increase in left ventricular end-systolic diameter(LVESD) and left ventricular end-diastolic diameter (LVEDD), an increase in the proportion of cardiac fibrosis area, an increase in relative expression levels of ANP, BNP, Col3α, and MYH7 mRNA, an increase in ROS mean fluorescence intensity, a decrease in SOD activity, an increase in mean fluorescence intensity of p-HDAC2, an increase in relative expression levels of p-HDAC2 and NOX1 proteins, and a decrease in relative expression levels of Nrf2, GPX4, and xCT proteins (P<0.05). Myocardial fibrosis lesions are obvious, with disordered mitochondrial arrangement, decreased volume and shrinkage, increased membrane density, and reduced mitochondrial cristae. Compared to the model group, the LVEF and LVFS of mice in each dose group of Xinyang Tablet and the perindopril group increased, LVESD and LVEDD decreased, the proportion of fibrotic area of heart tissue decreased, the relative expression levels of ANP, BNP, Col3α, MYH7 mRNA decreased, ROS mean fluorescence intensity decreased, SOD activity increased, mean fluorescence intensity of p-HDAC2 decreased, relative expression levels of p-HDAC2 and NOX1 proteins decreased, and relative expression levels of Nrf2 and xCT proteins increased (P<0.05). Myocardial fibrosis was reduced, the mitochondrial arrangement was more regular, the mitochondria enlarged, the membrane density was reduced, and mitochondrial cristae increased. Compared to the model group, the relative expression level of the GPX4 protein in myocardial tissue increased in the Xinyang Tablet medium-, high-dose, and the perindopril groups (P<0.05). Conclusion Xinyang Tablet can improve ferroptosis and ventricular remodeling in mice with chronic heart failure by regulating the HDAC2-mediated Nrf2 antioxidant pathway.

OBJECTIVE To analyze the distribution of the nasopharyngeal microbiota in children with refractory chronic sinusitis and adenoid hypertrophy using 16S rRNA next-generation high-throughput sequencing technology,and to compare the effects of adenoidectomy on the nasopharyngeal microbiota in such patients,with the aim of providing microbiological evidence for the clinical treatment of refractory chronic sinusitis with adenoid hypertrophy.METHODS Children diagnosed with chronic sinusitis with adenoid hypertrophy who visited Chengdu Women and Children's Central Hospital from January 2024 to March 2025 and whose symptoms were not controlled after drug treatment were selected.They were divided into a non-surgical group and a surgical group based on whether they underwent adenoidectomy.The VAS scores,Lund-Kennedy scores,and microbial community detection rates between the two groups were compared.RESULTS The final VAS scores and Lund-Kennedy scores for surgical group were both lower than those for non-surgical group,with statistically significant differences(tVAS score=3.491,P<0.001;tLund-Kennedy score=4.166,P<0.001).Comparisons of microbial α diversity analysis and β diversity at the phylum and genus levels between the two groups showed no statistically significant differences(tα diversity analysis=0.524,P=0.604;Rβ diversity at the phylum level=0.075,P=0.454;Rthe genus level=0.117,P=0.538).The dominant bacterial groups at the phylum level were the same in both groups,including Proteobacteria,Bacillales,Actinobacteria,Bacteroidetes,and Firmicutes,but the average relative abundance differed between the two groups.Species comparison analysis showed that at the phylum level,the abundance of Proteobacteria and Thermodesulfovibrio in surgical group was higher than that in non-surgical group;At the genus level,the abundance of the genus Moraxella was higher in non-surgical group than in surgical group,while the abundance of the genera Acidovorax,Stenotrophomonas,Delftia,Burkholderia,Caballeronia,Paraburkholderia,Lactobacillus,Devosia,norank_f_Muribaculaceae,Paracoccus,and Kocuria was lower in non-surgical group than in surgical group.CONCLUSION Children with refractory sinusitis and adenoid hypertrophy all have rich microbial communities in the nasopharynx.Adenoid surgery has no significant effect on the diversity of the nasopharyngeal microbial community.However,the composition of the microbial community has changed,and there are significant species differences,which may be related to the resolution of local obstruction after adenoidectomy and changes in the survival environment of the nasopharyngeal microbial community.

This article introduces Professor LIU Xing's clinical experience in treatment of peripheral facial paralysis at the recovery and sequelae stages with the combination of acupotomy, cupping and herbal medication. Based on the analysis of etiology and pathogenesis of peripheral facial paralysis, Professor LIU believes that "invasion of pathogenic wind to collaterals and obstruction of qi and blood" is crucial. Therefore, the treatment focuses on "dispelling wind and harmonizing blood". The compound therapeutic mode is proposed, with acupotomy, cupping and herbal decoction involved, in which, "three-step sequential method of acupotomy" is predominated. Firstly, in the prone position, five "feng" (wind) points are stimulated in patient, Fengfu (GV16), Fengchi (GB20), Yifeng (TE17), Bingfeng (SI12) and Fengmen (BL12). Secondly, in the lateral position, three-facial points are stimulated (FaceⅠneedle: Yangbai [GB14]-Yuyao [EX-HN4]; Face Ⅱ needle: Sibai [ST2]-Quanliao [SI18]; Face Ⅲ needle: Jiache [ST6]-Dicang [ST4]) to restore the deviated facial muscles. Finally, in the supine, two Dantian points are stimulated on the forehead and chest, respectively (upper Dantian: Yintang [GV24⁺], middle Dantian: Danzhong [CV17]), to regulate qi and blood. As the adjunctive therapies, cupping is used to remove stasis, and herbal decoction is to harmonize the body interior. In view of holistic regulation, the treatment is administered in accordance with the affected meridians, so as to expel wind, remove obstruction in collaterals and regulate qi and blood.

Objective Exploring the application effect of fragmented resistance exercise in the exercise rehabili-tation of elderly patients with chronic obstructive pulmonary disease,providing references for improving their quality of life.Methods From October to December 2024,96 elderly patients with chronic obstructive pulmonary disease admitted to a tertiary hospital in Pingdingshan city were conveniently selected as the research subjects.They were randomly divided into an experimental group and a control group(all n=48)using a random number table method.The experimental group received a fragmented resistance exercise program on the basis of routine pulmonary reha-bilitation,while the control group received routine pulmonary rehabilitation nursing care for a duration of 3 months.The lung function,exercise endurance,quality of life,and exercise compliance were compared between the 2 groups before and after intervention.Results The experimental group ultimately included 46 cases,while the control group ultimately included 47 cases.The lung function of the experimental group was better than that of the control group after 3 months of intervention(P＜0.05),and the exercise compliance scores of the experimental group were high-er than those of the control group after 1 and 3 months of intervention(P＜0.001).Repeated measures ANOVA showed that there was an interaction effect(P＜0.05)in the comparison of exercise endurance and quality of life between the 2 groups.Simple effects analysis showed that the experimental group had better exercise endurance after 3 months of intervention than the control group(P＜0.05),and better quality of life after 1 and 3 months of intervention than the control group(P＜0.05).Conclusion Fragmented resistance exercise can effectively improve lung function,enhance exercise endurance and compliance,and improve quality of life in elderly patients with chronic obstructive pul-monary disease.

Objective:To compare the differences of long-term survival rates between hemodialysis (HD) and peritoneal dialysis (PD) in the oldest old end-stage renal disease (ESRD) patients, and analyze the influencing factors of mortality.Methods:It was a retrospective cohort study. The clinical data from the oldest old patients (≥80 years old) who underwent HD or PD for the first time and maintained dialysis treatment for ≥3 months in the Zhejiang Dialysis Registration System from January 1, 2008 to December 31, 2021 were collected. The follow-up endpoint was until the patients' death or December 31, 2022. The propensity score matching method was used to match groups. Kaplan-Meier method and log-rank test were used to compare the differences of long-term survival rates between the two groups. Cox regression analysis was used to analyze the risk factors of mortality.Results:A total of 5 880 the oldest old dialysis patients were included in this study, with 5 363 patients in the initial HD group and 517 patients in the initial PD group. After matching, there were 517 patients in the HD group and 517 patients in the PD group. The median survival time of HD group before matching was 39.9 months, with 1-year, 3-year, and 5-year survival rates of 85.4%, 54.9%, and 30.0%, respectively. The median survival time of PD group was 32.9 months, with 1-year, 3-year, and 5-year survival rates of 82.5%, 47.1%, and 22.3%, respectively. After matching, the median survival time of HD group was 40.3 months, and the 1-year, 3-year, and 5-year survival rates were 86.1%, 57.8%, and 29.1%, respectively. The survival rate of PD group remained unchanged. The difference of 1-year survival rate between the two groups was not statistically significant, but the 2-year, 3-year, 4-year, 5-year, and overall survival rates in HD group were higher than those in PD group (Log‐rank test, χ2=4.897, P=0.027; χ2=9.693, P=0.002; χ2=10.194, P=0.001; χ2=7.868, P=0.005; χ2=12.510, P<0.001). Multivariate Cox regression analysis showed that HD (HD/PD, HR=0.794, 95% CI 0.669-0.943, P=0.009), increasing age ( HR=1.069, 95% CI 1.038-1.110, P<0.001), comorbidity with chronic obstructive pulmonary disease ( HR=1.510, 95% CI 1.065-2.139, P=0.021) and serum albumin <35 g/L ( HR=1.393, 95% CI 1.165-1.665, P<0.001) were independent correlated factors of mortality. Conclusions:There is no significant difference in the 1-year survival rate between HD and PD groups. The survival rate for more than 1 year in HD patients is higher than that in PD patients. HD is an independent protective factor of survival, and increasing age, comorbidities of chronic obstructive pulmonary disease, and serum albumin <35 g/L are independent risk factors affecting the survival in the oldest old dialysis patients.

Objective:To investigate the effect of intradialytic cerebral blood flow (CBF) fluctuation on cognitive decline in middle-aged and elderly maintenance hemodialysis (MHD) patients.Methods:It was a prospective cohort study. MHD patients aged ≥50 years from Beijing Shijitan Hospital were enrolled from January 2023 to June 2023. Middle cerebral artery mean flow velocity (MFV) was serially monitored via transcranial Doppler (TCD) during dialysis sessions. Cognitive function was assessed at baseline and after 12-month follow-up using standardized neuropsychological tests: montreal cognitive assessment (MoCA), auditory verbal learning test (AVLT 5), complex figure test (CFT), trail making test-B (TMT-B), Stroop color and word test (SCWT), and symbol digit modalities test (SDMT). ΔMFV was calculated as pre-to-post dialysis MFV difference. Multivariable linear regression was used to analyze the association of ΔMFV and cognition.Results:A total of 121 MHD patients were recruited with an age of (63.63±8.44) years. There were 97 males (80.2%), and the dialysis vintage was (55.08±54.73) months. Significant intradialytic MFV reductions were observed ( P<0.05). At 12 months, cognitive decline manifested in global cognition (MoCA), memory (CFT-memory), executive function (TMT-B, SCWT-C, SCWT-T), attention (SDMT), visuospatial ability (CFT-copy)(all P<0.05). Multivariable linear regression analysis revealed ΔMFV independently predicted declines in: MoCA ( B=0.066, 95% CI 0.018-0.113, P=0.007), AVLT5 ( B=0.050, 95% CI 0.004-0.097, P=0.035), TMT-B ( B=-1.955, 95% CI -3.453--0.457, P=0.011), SCWT-C ( B=0.298, 95% CI 0.112-0.484, P=0.002), SCWT-T ( B=-1.371, 95% CI -2.303--0.439, P=0.004). Conclusions:Hemodialysis induces acute CBF reductions detectable by TCD. Cumulative intradialytic CBF fluctuations may accelerate cognitive deterioration in middle-aged and elderly MHD populations, particularly affecting memory and executive domains.

Objective:To evaluate the long-term protective efficacy of the recombinant Chinese hamster ovary cell-derived hepatitis B vaccine（CHO-HepB）26 years post-vaccination in the rural China.Methods:Zhengding county，Hebei province was designated as a rural monitoring site for CHO-HepB efficacy. Study participants included individuals born between 1997 and 1999 who had completed the three-dose CHO-HepB primary series without booster doses. A cross-sectional survey was conducted in late 2024 using random sampling. Demographic and vaccination history data were collected via questionnaires，and hepatitis B virus（HBV）serological markers were detected using chemiluminescence. Historical surveillance data were integrated to infer infection statuses of HBsAg-positive individuals and evaluate longitudinal trends in anti-HBs seropositivity and antibody titers.Results:Among 178 participants（mean time since vaccination：26.2 years），the seroprevalence rates were 0.6% for HBsAg（95% CI：0.0%-1.6%），64.6% for anti-HBs（95% CI：57.6%-71.6%），and 1.1% for anti-HBc（95% CI：0.0%-2.7%）. Compared to the pre-vaccination baseline HBsAg positivity of 11.3% in children under 10 years of age，the estimated vaccine protection rate was 95%. Two notable cases were identified：one with concurrent HBsAg and anti-HBc positivity and one with anti-HBs and anti-HBc positivity，suggestive of transient HBV exposure（1999—2009）without chronicity. Natural immune boosting was inferred for the latter case based on anti-HBs titer dynamics. Longitudinal analysis of four prior cross-sectional surveys（2005，2009，2013，and 2017）revealed no significant upward trends in HBsAg and anti-HBc positivity（both P>0.05）over 26 years，while anti-HBs seropositivity declined significantly（ P<0.05）from 6 to 26 years post-vaccination. Conclusion:The CHO-HepB vaccine demonstrates sustained immunological persistence and robust long-term protection up to 26 years post-immunization. Continued emphasis on rigorous implementation of mother-to-child transmission prevention strategies is critical for future hepatitis B control.

Objective To analyze changes of preoperative T lymphocyte immunity and humoral immunity,and their relationship with pathological characteristics in patients with primary hepatocellular carcinoma(HCC).Methods A total of 150 patients with primary HCC underwent elective surgical treatment were enrolled as the HCC group,while 150 healthy controls during the same period were enrolled as the control group.Before surgery,the levels of peripheral blood CD3+,CD4+and CD8+were detected by flow cytometry,and CD4+/CD8+was calculated.The levels of IgA,IgG and IgM in peripheral blood were detected by immunoturbidimetry.The pathological characteristics of HCC patients were collected,and the differences of preoperative immune indexes in patients with different pathological characteristics were compared.The receiver operating curve(ROC)was used to evaluate the predictive value of immune indicators for pathological characteristics.Results The levels of CD3+,CD4+and CD4+/CD8+were lower in the HCC group than those in the control group,while levels of CD8+,IgA,IgG and IgM were higher in the HCC group than those in the control group(P＜0.05).The levels of CD3+,CD4+and CD4+/CD8+were lower in patients with lymph node metastasis than those of patients with distant lymph non-metastasis(P＜0.05).The levels of CD8+,IgA,IgG and IgM were higher in patients with lymph node metastasis than those of patients without metastasis(P＜0.05).The results of receiver operating characteristic(ROC)curves showed that area under the curve(AUC)values of CD3+,CD4+,CD8+,CD4+/CD8+,IgA,IgG,and IgM for predicting lymph node metastasis in HCC patients were 0.810,0.741,0.770,0.707,0.756,0.738 and 0.727.Conclusion There are abnormal changes of preoperative T lymphocyte immunity and humoral immunity in patients with primary HCC,which are closely related to lymph node metastasis.
