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.

ObjectiveTo investigate the feasibility, safety, and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt (SA-TIPS) in the treatment of portal hypertension comorbid with complex portal vein thrombosis, including cavernous transformation of the portal vein (CTPV). MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital, Capital Medical University, from November 2023 to January 2025, including general status, technical data of the surgical process (surgical success rate, puncture times, time of operation, the number of stents used, and the length of shunt), perioperative complications, and surgical recovery. The change in portal pressure gradient (PPG) after shunt was compared, and the rate of reaching the standard for PPG reduction was calculated, as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients, 34 (94.4%) underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% (6/36), including 3 cases of thoraco-abdominal hemorrhage, 2 cases of intraoperative arrhythmia, and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS (t=19.85, P<0.01), and the patients achieving a ≥50% reduction in PPG accounted for 76.5% (26/34). Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate, a favorable safety profile, and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis (including CTPV), and therefore, it holds promise for clinical application.

ObjectiveTo explore the mechanisms of Qingchang Wenzhong Decoction (清肠温中方, QWD) in treating ulcerative colitis (UC). MethodsA total of 100 male C57BL/6J mice were assigned to a pseudo-germ-free group (n=45) and a conventional group (n=55) using a random number table. Pseudo-germ-free model was established by giving antibiotic treatment and subsequently subjected to acute UC induction. After the model was successfully established, the 45 pseudo-germ-free acute UC mice were randomly allocated to a pseudo-germ-free model group, a pseudo-germ-free QWD group, and a pseudo-germ-free mesalazine group, with 15 mice in each group. The 55 conventional mice were randomly divided into a normal control group (n=10), as well as a conventional model group, a conventional QWD group, and a conventional mesalazine group, with 15 mice in each group. Except for the normal control group, acute UC models were established in all other groups. Mice in the control group received no intervention. From day 32 of the experiment, mice in the pseudo-germ-free QWD group and the conventional QWD group were administered with QWD granules at a dose of 9.71 g/(kg·d) by gavage with deionized water, while those in the pseudo-germ-free mesalazine group and the conventional mesalazine group were given mesalazine enteric-coated tablets at a dose of 151.67 mg/(kg·d) by gavage. Mice in the remaining groups received an equal volume of deionized water once daily for 7 consecutive days. On day 25 of the experiment, six mice were randomly selected from both the pseudo-germ-free group and the conventional group to measure body weight, and fecal samples were collected for 16S rDNA sequencing to compare differences in gut microbiota, including operational taxonomic units (OTUs), Shannon index, Observed_species index, and phylogenetic diversity (PD whole tree). On day 39, body weight was measured in all groups, and the disease activity index (DAI) was evaluated. Colon length and colon wet weight were recorded. Histopathological changes in colonic tissues were assessed by hematoxylin and eosin (HE) staining, and histological injury scores were determined. In addition, the expression levels of mucopolysaccharides and mucin 2 (MUC2) in colonic tissues were measured. ResultsOn day 25, there was no significant difference in body weight between the pseudo-germ-free group and the conventional microbiota group (P>0.05). Compared to the conventional microbiota group, the pseudo-germ-free group showed significantly reduced OTUs, Shannon index, Observed_species index, and PD whole tree (P<0.01). On day 39, compared to the normal control group, mice in the conventional model group showed a significant decrease in the body weight and an increase in DAI, along with increased colon wet weight, shortened colon length, markedly elevated histopathological scores, and reduced expression of mucopolysaccharides and MUC2 (P<0.01). In contrast, no significant differences were observed in these parameters in the pseudo-germ-free model group (P>0.05). Compared to the conventional model group, the conventional QWD group showed significant improvement in all measured parameters, whereas the conventional mesalazine group showed reductions only in DAI scores and colon wet weight (P<0.01). No statistically significant differences were observed among the pseudo-germ-free model group, the pseudo-germ-free QWD group, and the pseudo-germ-free mesalazine group (P>0.05). ConclusionQWD may promote the reconstruction of the intestinal mucus barrier by regulating the intestinal flora, thereby exerting a therapeutic effect on acute UC.

Objective:
To analyze the association between dietary diversity and cognitive function among the elderly using group-based trajectory model, so as to provide the basis for formulating dietary intervention strategies to prevent cognitive impairment.
Methods:
Based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS) project, demographic information, lifestyle behaviors, psychological well-being, and activities of daily living of elderly individuals aged ≥65 years from 2008 to 2018 were collected. Dietary diversity was assessed using a food frequency questionnaire, with a score of <7 points defined as low dietary diversity. Cognitive function was evaluated using the Chinese version of the Mini-Mental State Examination (MMSE). A group-based trajectory model was established based on cognitive function scores from 2008 to 2018 to analyze the trajectories of cognitive function change. The association between dietary diversity and cognitive function was analyzed using a multinomial logistic regression model.
Results:
A total of 1 613 individuals were collected, with a median age was 72.00 (interquartile range, 10.00) years. There were 810 males (50.22%) and 803 females (49.78%). The group-based trajectory model analysis categorized the participants into three groups: the low-level normal group, the high-level normal group, and the slow-then-rapid decline group, comprising 796 (49.35%), 585 (36.27%), and 232 (14.38%) individuals, respectively. Among these groups, the numbers of individuals with low dietary diversity were 497 (62.44%), 311 (53.16%), and 166 (71.55%), respectively, with a statistically significant difference (P<0.05). Multinomial logistic regression analysis showed that after adjusting for demographic information, lifestyle behaviors, psychological well-being, and activities of daily living, compared with the high-level normal group, low dietary diversity was statistically associated with cognitive function in the slow-then-rapid decline group (OR=1.622, 95%CI: 1.103-2.384).
Conclusion
Low dietary diversity may increase the risk of cognitive impairment among the elderly.

Flowering and bolting are important agronomic traits in cruciferous crops such as Brassica juncea. Timely flowering can ensure the crop organ yield and quality, as well as seed propagation. The WRKY family plays an important role in regulating plant bolting and flowering, while the function and mechanism of WRKY12 in B. juncea remain unknown. To explore its function and mechanism in bolting and flowering of B. juncea, we cloned and characterized the BjuWRKY12 gene in B. juncea and found that its expression levels were significantly higher in flowers and inflorescences than in leaves. BjuWRKY12 belonged to the Ⅱc subfamily of the WRKY family, and subcellular localization indicated that the protein was located in the nucleus. Ectopic overexpression of BjuWRKY12 in transgenic lines promoted bolting and flowering, leading to significant increases in the expression levels of flowering integrators SOC1 and FUL. Furthermore, yeast one-hybrid and dual luciferase reporter system assays confirmed that BjuWRKY12 directly bound to the promoters of BjuSOC1 and BjuFUL, undergoing protein-DNA interactions. This discovery gives new insights into the regulation network and molecular mechanisms of BjuWRKY12, laying a theoretical foundation for the breeding of high-yield and high-quality varieties of B. juncea.

Objective:To explore the longitudinal effect of learning stress on learning burnout in vocational college students, and the mediating role of academic procrastination.Methods:A total of 1 212 vocational college students were selected, and two follow-up surveys were conducted at 12-week intervals in September (T1) and November (T2) of 2024 using the basic situation questionnaire, the burnout inventory-student survey, the learning pressure questionnaire and the brief academic procrastination scale. SPSS 26.0 software was used to compare the demographic characteristics of students' depersonalization using t test and single factor analysis of variance. Bootstrap was used to analyze the relationship among learning stress, academic procrastination and learning burnout. Results:The scores of learning stress at T1 and T2 for vocational college students were 14.47±3.52 and 14.52 ±3.50, the scores of academic procrastination at T1 and T2 were 27.14±9.07 and 27.21±9.04, and the scores of learning burnout T1 and T2 were 39.38±8.76 and 39.69±8.79.The t-test showed that the score of learning burnout at T1 of students aged 18 and below (36.70±8.72) was lower than students aged 18 above (40.15±8.63, t=-5.81, P<0.01). The score of learning burnout for liberal arts students at T1(40.82±8.54) was higher than that of science students (37.68±8.72, t=6.31, P<0.01). Single factor analysis of variance showed that the score of learning burnout for grade 1 students at T1(35.19±8.45) was lower than that of grade 2 students (41.33±7.98) and grade 3 students (38.92±9.88), and learning burnout score of grade 2 students at T1 was higher than that of grades 3 students ( F=61.59, P<0.01). The score of learning burnout for high-achieving students at T1(36.23±8.34) was lower than that of middle-achieving students (39.82±8.52) and low-achieving students (45.42±9.14), and the score of learning burnout for middle-achieving students at T1 were lower than that of low-achieving students ( F=36.53, P<0.01). Bootstrap test showed that academic procrastination T2 played a partial mediating role in the relationship between learning stress T1 and learning burnout T2 (effect size=0.04, 95% CI=0.03-0.07). Academic procrastination T1 played a partial mediating role in the relationship between learning stress T1 and learning burnout T2 (effect size=0.05, 95% CI=0.04-0.07). Conclusion:Learning stress can directly affect learning burnout in vocational college students, and also can indirectly affect learning burnout through the mediating effect of academic procrastination.
