ObjectiveTo observe the clinical efficacy of Sanren Runchang formula in treating constipation-predominant irritable bowel syndrome （IBS-C） by regulating the brain-gut axis and the effects of the formula on serum levels of 5-hydroxytryptamine （5-HT）， vasoactive intestinal peptide （VIP）， and substance P （SP）. MethodsA randomized controlled design was adopted， and 72 IBS-C patients meeting Rome Ⅳ criteria were randomized into observation and control groups （36 cases）.The observation group received Sanren Runchang formula granules twice daily， and the control group received lactulose oral solution daily for 4 weeks. IBS Symptom Severity Scale （IBS-SSS）， IBS Quality of Life Scale （IBS-QOL）， and Bristol Stool Form Scale （BSFS） were used to assess clinical symptoms， and bowel movement frequency was recorded. The Self-Rating Anxiety Scale （SAS） and Self-Rating Depression Scale （SDS） were employed to evaluate psychological status. ELISA was employed to measure the serum levels of 5-HT， VIP， and SP. ResultsThe total response rate in the observation group was 91.67% （33/36）， which was higher than that （77.78%， 28/36） in the control group （χ²=4.50， P<0.05）. After treatment， both groups showed increased defecation frequency and BSFS scores， decreased IBS-SSS total score， abdominal pain and bloating scores， IBS-QOL health anxiety， anxiety， food avoidance， and behavioral disorders scores， SAS and SDS scores， serum 5-HT and VIP levels， and increased SP levels （P<0.05， P<0.01）. Moreover， the observation group showed more significant changes in the indicators above than the control group （P<0.05， P<0.01）. The SP level showed no significant difference between the two groups. During the 4-week follow-up， the recurrence rate was 5.88% in the observation group and 31.25% in the control group. No adverse events occurred in observation group， and 2 cases of mild diarrhea occurred in the control group. ConclusionSanren Runchang formula demonstrated definitive efficacy in alleviating gastrointestinal symptoms and improving the psychological status and quality of life in IBS-C patients， with a low recurrence rate. The formula can regulate serum levels of neurotransmitters such as 5-HT and VIP， suggesting its potential regulatory effect on the brain-gut axis through modulating neurotransmitters and neuropeptides. However， its complete mechanism of action requires further investigation through detection of additional brain-gut axis-related biomarkers.

Chronic liver diseases are a group of diseases in which the liver is subjected to a variety of injuries over a long period of time， resulting in irreversible pathological changes that last longer than 6 months. Emodin （EMO） is a natural anthraquinone derivative derived from Rheum officinale， and its pharmacological effect has been extensively studied， exhibiting a variety of biological properties and involving multiple signaling molecules and pathways. Western medicine or surgical treatment is currently the main treatment regimen for chronic liver diseases， and the advance in treatment is limited by various reasons such as side effects and high costs. Due to its natural origin and efficacy， EMO has unique advantages in the treatment of chronic liver diseases and has now become a research hotspot. This article summarizes the therapeutic effect of EMO on chronic liver diseases and its mechanism， in order to provide a certain scientific basis for the traditional Chinese medicine treatment of chronic liver diseases and the development of drugs in clinical practice.

Objective To investigate the association between single nucleotide polymorphisms(SNP)rs57095329 and rs6864584 of miR-146a gene and cervical intraepithelial neoplasia(CIN).Methods A total of 96 patients diagnosed with CIN were randomly collected as the CIN group,and 225 healthy individuals examined during the same period were selected as the control group using SPSS software.Genotyping of the above SNP loci was performed using the TaqMan probe method,and their correlation with CIN was analyzed.Results The allele and genotype distribution of rs57095329 showed a statistically significant differences compared to the control group,with the frequency of the allele A in the CIN group significantly lower than that in the control group(P<0.001;OR=0.48,95%CI:0.32～0.70).In the dominant model,individuals carrying the G allele(A/G-G/G)had a significantly increased risk of CIN(P<0.001;OR=2.67,95%CI:1.64～4.37).In contrast,no correlation was found between the rs6864584 and the risk of CIN.Conclusion The A allele of the miR-146a gene at the rs57095329 locus may be a protective factor for CIN.

Background: Hypertension is a major risk factor for cardiovascular diseases, including AF, which is one of the most common cardiac arrhythmias globally. AF is strongly associated with an increased risk of stroke, heart failure (HF), and cardiovascular mortality. Although intensive blood pressure lowering has been shown to reduce adverse cardiovascular events, its effect on the risk of AF remains debated. Some studies suggest a beneficial effect, whereas others are inconclusive. Therefore, a comprehensive review and meta-analysis are needed to clarify these effects. Objective: This study aims to evaluate the impact of intensive blood pressure lowering on the incidence of atrial fibrillation (AF) in hypertensive patients. Methods: We performed a systematic review and meta-analysis by searching PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Library up to September 2, 2024, for randomized controlled trials comparing intensive blood pressure lowering with standard treatment in hypertensive patients. Studies were included if participants were 40 year or older with systolic blood pressure between 130 and 180 mm Hg (1 mm Hg≈0.133 kPa). Data extraction was conducted by 2 independent researchers, and statistical analysis was performed using Review Manager (RevMan) 5.4. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. A random-effects model was applied if heterogeneity was detected (I > 50%). Results: A total of 6 randomized controlled trials involving 34,824 participants were included in the analysis. Intensive blood pressure lowering significantly reduced the risk of new-onset AF compared with standard treatment (RR = 0.76, 95% CI = 0.62-0.93, p < 0.01, I = 0%). Reductions were also observed in stroke (RR = 0.71, 95% CI = 0.58-0.87, p < 0.005, I = 7%), HF (RR = 0.67, 95% CI = 0.45-0.99, p = 0.05, I = 53%), and nonfatal coronary events (RR = 0.80, 95% CI = 0.70-0.92, p < 0.005, I = 39%). However, intensive blood pressure lowering had no significant effect on cardiovascular mortality or all-cause mortality compared with standard treatment. Discussion: Intensive blood pressure lowering significantly reduces the risk of AF and other cardiovascular events, such as stroke, HF, and nonfatal coronary events, particularly among high-risk hypertensive patients. These findings support the potential benefits of intensive blood pressure management in reducing AF incidence and improving overall cardiovascular outcomes, but the evidence is limited.

This case report introduces Professor ZOU Wei 's experience of treating a patient with Wernicke encephalopathy using the "regulating spirit and promoting yang acupuncture method". The patient was diagnosed as spleen and stomach deficiency with internal liver wind. The treatment principle focused on regulating spirit and awakening the brain, strengthening the spleen, calming wind, and relaxing the tendons. Three groups of acupoints were selected: ①acupoints for awakening the brain by regulating spirit and unblocking meridians (Baihui [GV20], Qianshencong [EX-HN1] and bilateral Taiyang [EX-HN5], Fengchi [GB20]), etc.; ②acupoints for harmonizing the spleen, stomach, qi, and blood (bilateral Tianshu [ST25], Daheng [SP15], Taixi [KI3], etc.); ③acupoints for relaxing and softening the tendons (bilateral Waiguan [TE5], Hegu [LI4], Yanglingquan [GB34], Xuanzhong [GB39]).The needles were retained for 50 min per session, once daily, 7 days a week. After 16-week treatment, the patient was able to walk a few steps slowly with assistance, and other symptoms returned to normal. A two-month follow-up showed the patient's condition remained stable, walking distance further increased, and overall health significantly improved.

Objective To determine the scores of patients with a confirmed diagnosis of drug-induced liver injury(DILI)using Roussel Uclaf Causality Assessment Method(RUCAM),Maria&Victorino assessment scale,and Revised Electronic Causality Assessment Method(RECAM),to compare the accuracy of the three scales in diagnosis,and to investigate their clinical significance in the diagnosis of DILI.Methods A total of 98 patients with a confirmed diagnosis of DILI who were hospitalized in Peking University First Hospital from January 2011 to December 2022 were enrolled,with liver biopsy results supporting DILI and a clear history of medication.Clinical data were collected from all subjects,and the above causality assessment scales were used for scoring.The chi-square test was used to analyze the diagnostic accuracy of the causality assessment scales,and the weighted kappa coefficient was used to analyze the consistency between the three scales.Results For all patients with DILI enrolled,RECAM had the highest accuracy,with a significant difference compared with RUCAM(χ2=5.667,P=0.017).RUCAM and RECAM had moderate consistency in diagnosis(κw=0.469),while RECAM and Maria&Victorino scale had poor consistency(κw=0.156).For the patients with acute DILI,RECAM,RUCAM,and Maria&Victorino scales had a diagnostic inconsistency rate of 3.7%,11.1%,and 42.6%,respectively;for the patients with hepatocellular type DILI,the three scales of a diagnostic inconsistency rate of 8.9%,21.4%,and 62.5%,respectively;for the patients with cholestasis type or mixed type DILI,the three scales of a diagnostic inconsistency rate of 10.0%,22.5%,and 47.5%,respectively.Conclusion The use of RECAM and RUCAM scales in acute DILI can improve diagnostic rate,and for hepatocellular type DILI and DILI with the clinical manifestation of cholestasis(cholestasis type DILI and mixed type DILI),the use of RECAM and RUCAM scales can also improve diagnostic rate.The selection of causality assessment scales with a relatively high accuracy based on the course and clinical classification of the disease may help to further improve clinical diagnostic rate.

Objective:A subunit vaccine against SARS-CoV-2 BA.2 variant was prepared by prokaryotic expression system and its immunogenicity was evaluated.Methods:The recombinant plasmid of BA.2 variant RBD and the tandem of RBD and TT-P2 epitopes was constructed by molecular cloning technology, and recombinant proteins So and Sot were obtained by protein purification technology. Mice were immunized by intramuscular injection after mixing protein So/Sot as immunogens with Al(OH) 3 adjuvant to evaluate the effect of cellular and humoral immunity. Results:High purity soluble protein were obtained by dialysis and renaturation after expressed by prokaryotic system. The number of antigen-specific T lymphocytes secreting IFN-γ and IL-4 (213.7±0.6 and 311.7±1.5) in the Sot group induced by mice was significantly higher than that in the So group (94.3±16.8 and 185.7±4.2) ( P<0.001). The serum antibody level induced by Sot group was higher than that in the So group, the geometric mean titer (GMT) of neutralizing antibodies against BA.2 strain were 588 and 337, respectively ( P<0.05). Sot protein induced Th1/Th2 mixed type immune response with the predominance of Th2 type. Conclusions:The protein subunit vaccine expressed by the prokaryotic system have excellent cellular and humoral immunogenicity, which provides a strong theoretical basis for the development of the protein subunit vaccines of the SARS-CoV-2 Omicron variant.

Objective: To examine the association between inflammatory cytokines and arrhythmias using two-sample bidirectional Mendelian randomization (MR) approach, so as to provide the basis for the prevention and treatment of arrhythmias. Methods: Data of 91 types of inflammatory cytokines were collected from a meta-analysis of genome-wide association studies (GWAS), and data of 7 types of arrhythmia were collected from GWAS database of susceptibility genes. A forward MR analysis was performed using the inverse variance weighted method with inflammatory cytokines as exposure and arrhythmias as the outcome, and a reverse MR analysis was performed with arrhythmias as exposure and inflammatory cytokines as the outcome. The positive and negative direction of association was evaluated using MR Steiger test. The sensitivity analysis were assessed using the Cochran's Q test, MR-PRESSO test and MR-Egger regression. Results: Forward MR analysis results showed that fractalkine (OR=1.231), fibroblast growth factor 5 (OR=1.105) and tumor necrosis factor (TNF)-related activation cytokine (OR=0.848) were statistically associated with ventricular arrhythmias (all P<0.05). CD40L receptor (OR=0.970), fibroblast growth factor 5 (OR=1.071), FMS-related tyrosine kinase 3 ligand (OR=0.958), and monocyte chemotactic protein-2 (OR=1.020) were statistically associated with atrial fibrillation (all P<0.05). TNF-related activation cytokine (OR=1.125) was statistically associated with paroxysmal tachycardia (P<0.05). Interleukin-15 receptor subunit α (OR=1.001) was statistically associated with bradycardia (P<0.05). C-C motif chemokine ligand 28 (OR=1.974) and interleukin-7 (OR=1.738) were statistically associated with right bundle branch block (both P<0.05). TNF superfamily member 14 (OR=0.784) was statistically associated with left bundle branch block (P<0.05). CXC motif chemokine ligand 11 (OR=1.277), interleukin-12B (OR=1.127), matrix metalloproteinase-1 (OR=1.333), stem cell factor (OR=0.874), and TNF-β (OR=1.152) were statistically associated with atrioventricular block (all P<0.05). Cochran's Q test detected no heterogeneity, and neither the MR-Egger regression nor the MR-PRESSO test revealed horizontal pleiotropy of instrumental variables (all P>0.05). Reverse MR analysis showed no association between gut microbiota and constipation (all P>0.05). Conclusion Among the 91 types of inflammatory cytokines, 12 types were associated with increased risk of arrhythmias and 5 types were associated with decreased risk of arrhythmias.
