This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Loss of protein homeostasis is a hallmark of cellular senescence, and ribosome pausing plays a crucial role in the collapse of proteostasis. However, our understanding of ribosome pausing in senescent cells remains limited. In this study, we utilized ribosome profiling and G-quadruplex RNA immunoprecipitation sequencing techniques to explore the impact of RNA G-quadruplex (rG4) on the translation efficiency in senescent cells. Our results revealed a reduction in the translation efficiency of rG4-rich genes in senescent cells and demonstrated that rG4 structures within coding sequence can impede translation both in vivo and in vitro. Moreover, we observed a significant increase in the abundance of rG4 structures in senescent cells, and the stabilization of the rG4 structures further exacerbated cellular senescence. Mechanistically, the RNA helicase DHX9 functions as a key regulator of rG4 abundance, and its reduced expression in senescent cells contributing to increased ribosome pausing. Additionally, we also observed an increased abundance of rG4, an imbalance in protein homeostasis, and reduced DHX9 expression in aged mice. In summary, our findings reveal a novel biological role for rG4 and DHX9 in the regulation of translation and proteostasis, which may have implications for delaying cellular senescence and the aging process.

Background: Normalized creatinine-to-cystatin C ratio (NCCR) was reported to approximate relative skeletal muscle mass and diabetes risk. However, the association between NCCR and cardiometabolic multimorbidity (CMM) remains elusive. This study aimed to explore their relationship in a large-scale prospective cohort. Methods: This study included 5,849 middle-age and older participants from the China Health and Retirement Longitudinal Study (CHARLS) enrolled between 2011 and 2012. The baseline NCCR was determined as creatinine (mg/dL)/cystatin C (mg/L)×10/body mass (kg). CMM was defined as the simultaneous occurrence of two or more of the following conditions: heart disease, stroke, and type 2 diabetes mellitus. Logistic regression analysis and Cox regression analysis were employed to estimate the relationship between NCCR and CMM. The joint effect of body mass index and NCCR on the risk of CMM were further analyzed. Results: During a median 4-year follow-up, 227 (3.9%) participants developed CMM. The risk of CMM was significantly decreased with per standard deviation increase of NCCR (odds ratio, 0.72; 95% confidence interval, 0.62 to 0.85) after adjustment for confounders (P<0.001). Further sex-specific analysis found significant negative associations between NCCR and CMM in female either without or with one CMM component at baseline, which was attenuated in males but remained statistically significant among those with one basal CMM component. Notably, non-obese individuals with high NCCR levels had the lowest CMM risk compared to obese counterparts with low NCCR levels in both genders. Conclusion High NCCR was independently associated with reduced risk of CMM in middle-aged and older adults in China, particularly females.

Objective:To evaluate the clinical efficacy of the V-shaped bone tunnel technique at the base of the distal phalanx for treating tendinous mallet finger.Methods:A retrospective analysis was conducted on clinical data from patients with tendinous mallet finger treated in the Department of Hand and Foot Surgery at Linyi People’s Hospital between August 2022 and November 2023. Two oblique bone tunnels were created in a V-shaped configuration at the dorsal base of the distal phalanx, adjacent to the extensor tendon insertion, using a 0.8 mm Kirschner wire. A 4-0 double-needle monofilament tendon suture was passed through the tunnels to secure the ruptured extensor tendon to the base of the distal phalanx, followed by fixation of the distal interphalangeal (DIP) joint with a 1.0 mm Kirschner wire. The Kirschner wire was removed at 4 weeks postoperatively to initiate functional exercises. Regular follow-up was conducted to monitor wound healing and functional recovery of the DIP joint. At the final follow-up, the range of flexion and extension of the DIP joint was measured, and treatment outcomes were evaluated using Crawford’s mallet finger evaluation criteria, which classified results into four grades: excellent, good, fair, and poor.Results:Fifteen patients (16 fingers) were included, comprising 11 males and 4 females, with a mean age of 44.5 years (range: 17-65 years). The injured fingers included 2 index, 4 middle, 5 ring, and 5 little fingers, all presenting with DIP joint flexion deformity and limited active extension. Postoperative follow-up ranged from 6 to 28 months (mean: 17 months). All wounds healed primarily without complications such as infection or skin necrosis, and no cases of tendon re-rupture occurred. At the final follow-up, the measurement results of flexion and extension range of motion of the affected fingers at the DIP joint were as follows: the maximum flexion angle of all 16 fingers was 45°, among which 7 fingers had an extension angle of 0°, 8 fingers had limited extension ranging from 1° to 10°, and 1 finger had limited extension of 15°. Among the 16 fingers, 7 fingers were rated as excellent, 8 fingers as good and 1 finger as fair.Conclusion:The V-shaped bone tunnel technique for tendon-to-bone reattachment of the extensor tendon insertion is a simple and effective method for treating tendinous mallet finger. It provides satisfactory functional recovery, improves finger appearance, and is associated with minimal complications.

Cervical chylous leakage is rare after central lymph node dissection for thyroid cancer, and the coexistence of chylothorax is even more uncommon. This article reports a case of a 39-year-old female patient who underwent total thyroidectomy and left central lymph node dissection for papillary thyroid carcinoma complicated by follicular adenoma. On the second postoperative day, the patient developed white, milky drainage from the neck, suggesting chylous leakage, and experienced mild chest tightness, cough, and low-grade fever. Chest CT revealed bilateral pleural effusion, with the left side being more severe. On the third day, ultrasound-guided left-sided pleural puncture and drainage were performed and hydrothorax triglycerides and total cholesterol levels were measured, chylothorax were diagnosed as a result.After conservative treatment including a low-fat diet, fasting, nutritional support, neck pressure dressing and negative pressure suctionand closed chest drainage, the patient's condition improved rapidly. The patient was discharged on the 8th postoperative day with full recovery. No recurrence has been observed during follow-up to date.

Objective:To evaluate the prevalence of hepatitis C virus (HCV) infection among patients attending a comprehensive tertiary hospital in Beijing and to pinpoint the key demographics for anti-HCV screening.Methods:A comprehensive retrospective analysis was undertaken, examining data from 631 424 patients who underwent anti-HCV testing between 2017 and 2023. Testing for anti-HCV was conducted using the Abbott i2000 fully automated chemiluminescent immunoassay analyzer. HCV nucleic acid testing was performed with the Roche Cobas AmpliPrep/Cobas TaqMan 96 fluorescent quantitative PCR system, while HCV genotyping was achieved through sequencing.Results:The positive rate of HCV antibodies demonstrated a gradual decline over the years, decreasing from 1.62% in 2017 to 1.01% in 2023. The overall positive rate stood at 1.36% (8 574/631 424), with a nucleic acid testing rate of 59.24% (5 079/8 574) and a nucleic acid positive rate of 34.28% (1 741/5 079). The majority of anti-HCV positive patients came from the department of hepatology (12.17%), followed by hepatobiliary surgery (3.03%), emergency medicine (1.68%), cardiovascular medicine (1.24%) and ophthalmology clinic (1.23%). Notably, the anti-HCV positive rate was significantly elevated in the ≥40 years old group compared to the <40 years old group, with statistical significance ( χ2=1 892.577, P=0.000). The highest anti-HCV positive rates were observed within the 60-69- and 80-99-years old brackets (both at 1.85%), while the peak HCV RNA positive rate was recorded in the 50-59 years old group (27.08%). Females exhibited a significantly higher positive rate (18.53%) than males (15.75%) ( χ2=8.066, P<0.01). When anti-HCV levels surpassed 9 S/CO, the HCV RNA positive rate was notably high, exceeding 38.97%. Intriguingly, at antibody levels ranging from 15 to 16 S/CO, the HCV RNA positive rate climbed to a maximum of 56.17%. Conclusions:This study has successfully identified the key populations for anti-HCV screening: Patients aged over 40, particularly female patients within the 50-69 age bracket; Patients in hepatology, hepatobiliary surgery, emergency medicine, cardiovascular medicine and ophthalmology departments.

Objective:To explore the predictive value of baseline serum levels of hepatitis B virus (HBV) RNA for HBeAg seroconversion in chronic hepatitis B (CHB) subjects with advanced fibrosis/compensated cirrhosis undergoing tenofovir disoproxil fumarate (TDF) therapy.Methods:A case-control study was conducted on 141 patients with CHB combined with advanced fibrosis/compensated cirrhosis who were treated with TDF and tested at Peking University People′s Hospital from January 2015 to December 2020. Patients were divided into HBeAg seroconversion (16 cases) group and non-seroconversion (59 cases) group based on whether HBeAg seroconversion occurred at 240 weeks after treatment. The patients were divided into HBeAg positive and negative groups at baseline (75 and 66 cases, repectively) and at 12 weeks treatment (61 and 80 cases, repectively). The baseline serum levels of relevant indicators were analyzed. HBV RNA levels were measured at baseline and at 240 weeks after treatment. The correlation between HBV RNA and HBV DNA was analyzed using Pearson correlation analysis, and the predictive value was evaluated using the receiver operating characteristic (ROC) curve.Results:For the 75 HBeAg-positive patients at baseline, 21.3% (16/75) achieved HBeAg seroconversion. The HBV DNA and HBV RNA in the HBeAg-positive group were significantly higher than that in the HBeAg-negative group (all P<0.001). Compared with the non-seroconversion group, the HBeAg seroconversion group had significantly lower baseline serum levels of HBV RNA ( P<0.05). Pearson correlation analysis showed that serum HBV RNA levels were positively correlated with HBV DNA in both baseline and 12 weeks HBeAg-negative group and HBeAg-positive group, respectively (baseline: r=0.718, 0.794, P<0.001; 12 weeks: r=0.689, 0.750, P<0.001). ROC curve showed that baseline levels of HBV RNA could be used as a predictor of HBeAg seroconversion in CHB patients with advanced fibrosis/compensated cirrhosis treated with TDF. The area under curve was 0.781, the sensitivity was 75.0%, and the specificity was 78.0%. Conclusion:Baseline serum levels of HBV RNA has a predictive value for HBeAg seroconversion in CHB patients with advanced fibrosis/compensated cirrhosis treated with TDF.

Objective Based on the clinical data and imaging manifestations of patients with ischemic stroke to establish a simple clinical prediction model that is used for identifying intracranial atherosclerotic stenosis-acute large vessel occlusion(ICAS-LVO in posterior circulation before surgery.Methods The clinical data of patients with acute large vessel occlusion(LVO in the posterior circulation,who received endovascular intervention at the First Affiliated Hospital of Nanjing Medical University of China from January 2019 to September 2022,were retrospectively analyzed.According to the intraoperative angiographic findings,the patients were divided into ICAS-LVO group and non-ICAS-LVO group.Univariate analysis and multivariate logistic regression analysis were used to analyze the patient's demographic characteristics,clinical history,imaging findings,and laboratory results,based on which a clinical prediction model for ICAS-LVO was established,and according to the relevant parameters a nomogram prediction model was plotted.Results A total of 110 patients with LVO in the posterior circulation who received endovascular treatment were included in the final analysis.In 51 patients(49.6％)the cause of vascular occlusion was the atherosclerotic stenosis of the intracranial arteries.Compared with non-ICAS-LVO group,in ICAS-LVO group the patients were younger,the incidence of atrial fibrillation was lower,and the level of plasma D-dimer was lower.Three factors,including atrial fibrillation,occlusion site and collateral circulation status,were finally screened out to establish the prediction model for ICAS-LVO.This model demonstrated acceptable calibration(Hosmer-Lemeshow test,P=0.562)and good discrimination ability(AUC=0.956;95％CI:0.906-0.986).Conclusion The clinical prediction model for ICAS-LVO,which is established on the three predictive factors(absence of atrial fibrillation,occlusion located at the V4 segment of the vertebral artery or at the proximal to mid segment of the basilar artery,and a favorable collateral circulation),carries high sensitivity and accuracy.This model can help neurointervention physicians to make early identification of ICAS-LVO and to promptly formulate vascular recanalization treatment strategies.

Abstract Breastfeeding has an irreplaceable effect on the growth and development of premature infants and the reduction of complications during hospitalization. In recent years, with the opening of China′s birth policy, the incidence of premature babies has increased, and the corresponding complications have also gradually increased. Breast milk not only carries a rich supply of nutrients, including rich proteins, lipids, sugars to support the normal growth and development of infants, but also contains a large number of immunoglobulins, hormones and other bioactive substances to promote the improvement of body immune function and the development of nervous system. In recent years, many studies have been carried out on the current situation of breast milk operation in breast milk bank, the collection and influencing factors of breast milk, the strategies of breast milk enrichment and its effects on the growth and development of premature infants and complications. Therefore, breast-feeding and intensive breast-feeding can effectively promote the growth and development of premature infants, and reduce the occurrence of complications.
