OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

BACKGROUND:Satellite cells are myogenic stem cells located between the muscle fiber membrane and the basement membrane.However,a comprehensive review of the aging mechanisms of satellite cells and their potential mitigation strategies is still lacking.This gap in knowledge hinders the effective guidance for current strategies aimed at attenuating skeletal muscle aging. OBJECTIVE:To review the mechanisms of satellite cell aging in skeletal muscle and the relevant strategies for mitigating this aging process. METHODS:Major databases were searched up to May 2023,including Web of Science,PubMed,China National Knowledge Infrastructure(CNKI),WanFang Data,and VIP.Chinese and English search terms included"skeletal muscle,satellite cells,aging,mechanism,and solution strategy".After strict inclusion and exclusion criteria were applied,78 articles were finally included. RESULTS AND CONCLUSION:(1)Satellite cells,situated between the muscle fiber membrane and basement membrane,possess proliferative and differentiative potential.They usually remain in a quiescent state but become activated in response to muscle tissue stimuli,participating in processes of repair and restoration of normal tissue structure.Aging leads to a reduction in satellite cell numbers,resulting in symptoms such as muscle weakness and decreased endurance.(2)Mechanisms of satellite cell aging primarily involve diminished regenerative capacity,perturbed niche interactions with changing ecology,age-dependent loss,and heterogeneity changes.Reduced satellite cell numbers and activity due to aging lead to slower muscle regeneration and increased injury recovery time.Errors during differentiation may occur,resulting in decreased muscle quality and function deterioration.(3)Strategies for mitigating satellite cell aging encompass modulation of the receptor environment of intra-body satellite cells,peripheral interventions to promote satellite cell regeneration,construction of human muscle models,and exercise and nutritional interventions to induce satellite cell proliferation.These strategies hold promise in offering novel insights and methods for satellite cell regeneration and treatment of skeletal muscle diseases.(4)Future research should delve into the mechanisms of satellite cell aging,explore the interaction between satellite cells and their niches,investigate the relationship of satellite cells with the immune system and mitochondrial function,and develop human muscle models to enhance research depth and accuracy.

Objective: To assess the efficacy and cost-effectiveness of high-dose dual therapy compared with bismuth-containing quadruple therapy for treating Helicobacter pylori(H.pylori) infection in servicemen patients. Methods: A total of 160 H. pylori-infected, treatment-naive servicemen, including 74 men and 86 women, aged from 20 years to 74 years, with a mean (SD) age of 43 (13) years, tested in the First Center of Chinese PLA General Hospital from March 2022 to May 2022 were enrolled in this open-label, randomized controlled clinical trial. Patients were randomly allocated into 2 groups: the 14-day high-dose dual therapy group and the bismuth-containing quadruple therapy group. Eradication rates, adverse events, patient compliance, and drug costs were compared between the two groups. The t-test was used for continuous variables, and the Chi-square test for categorical variables. Results: No significant difference in H. pylori eradication rates were found between high-dose dual therapy and bismuth-containing quadruple therapy by ITT, mITT and PP analysis[ITT:90.0% (95%CI 81.2%-95.6%) vs. 87.5% (95%CI 78.2%-93.8%), χ²=0.25, P=0.617;mITT:93.5% (95%CI 85.5%-97.9%) vs. 93.3% (95%CI 85.1%-97.8%), χ²<0.01, P=1.000; PP: 93.5% (95%CI 85.5%-97.9%) vs. 94.5% (95%CI 86.6%-98.5%), χ²<0.01, P=1.000 ]. The dual therapy group exhibited significantly less overall side effects compared with the quadruple therapy group [21.8% (17/78) vs. 38.5% (30/78), χ²=5.15,P=0.023]. There were no significant differences in the compliance rates between the two groups [98.7%(77/78) vs. 94.9%(74/78), χ²=0.83,P=0.363]. The cost of medications in the dual therapy was 32.0% lower compared with that in the quadruple therapy (472.10 RMB vs. 693.94 RMB). Conclusions: The dual regimen has a favorable effect on the eradication of H. pylori infection in servicemen patients. Based on the ITT analysis, the eradication rate of the dual regimen is grade B (90%, good). Additionally, it exhibited a lower incidence of adverse events, better compliance and significantly reduced cost. The dual regimen is expected to be a new choice for the first-line treatment of H. pylori infection in servicemen but needs further evaluation.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Clinical practice using associating liver partition and portal vein ligation for staged hepatectomy(ALPPS) or its modified procedures in treatment of primary hepatocellular carcinoma(HCC) with insufficient future liver remnant(FLR) in the past 10 years has failed to meet our expectations both in achieving decreased perioperative complications and mortality.The efficacy of ALPPS in improving long-term survival outcome of HCC still remains poor.Due to the trauma of two surgery within a short period,and patients with inadequate FLR are all diagnosed at advanced disease stages,ALPPS can only achieve surgical rather than biological tumor-curability.Previous studies have demonstrated comparable 5-year survival rates between early and advanced stages of HCC who underwent regional treatments.Therefore,tumor biological conversion is the key strategy prior to liver remnant volume conversion in improving treatment outcomes for HCC patients with insufficient FLR.Target therapy,immunotherapy together with locally treatment were expected to improve the conversion efficacy.Looking back at the development of ALPPS for the last decade,the rapid proliferation of FLR should be passed on,while the technology costs high risks and result in poor long-term outcome must be cautiously selected.

Dry eye is a multifactorial disease, which seriously affect the work and life of patients. Since the pathogenesis of dry eye has not been clarified so far, there is no standard animal model available now. Non-Sjögren syndrome dry eye is one of the main types of dry eye, which requires further research. Studies on dry eye mechanisms have led to the development and improvement of animal models. In this paper, the methods of animal models of non-Sjögren syndrome dry eye, including drug treatments, surgery, exogenous injury, behavioral patterns, changes in diet, are reviewed. In addition,different models are described, the problems are analyzed and perspectives and reflections on future research are offered.

ObjectiveTo observe the effects of modified Chaihu Shugansan（CHSG） and its disassembled formulas on angiotensin-converting enzyme 2 （ACE2）-angiotensin （Ⅰ-Ⅶ） ［Ang （Ⅰ-Ⅶ）］-mitochondrial assembly receptor （MasR） axis in hyperlipidemic rats with myocardial ischemia and depression， and to explore the underlying mechanism of its prevention and treatment of myocardial ischemia and depression. MethodA total of 108 male SD rats were randomly divided into a normal group， a model group， a modified CHSG group （11.7 g·kg^-1）， a Quyu Huatan disassembled formula group （4.05 g·kg^-1）， a Shugan Xingqi disassembled formula group （3.15 g·kg^-1）， a Jianpi Yangxue disassembled formula group （4.5 g·kg^-1）， a fluoxetine group （0.001 8 g·kg^-1）， a trimetazidine group （0.005 4 g·kg^-1）， and a simvastatin group （0.001 8 g·kg^-1）， with 12 rats in each group. The hyperlipidemia model with myocardial ischemia and depression was induced with a high-fat diet combined with injection of isoproterenol （ISO） and chronic unpredictable mild stress （CUMS） in rats in the model group and groups with drug intervention for eight weeks. The rats in each group with drug intervention were treated correspondingly by gavage from the first day of modeling， while those in the normal group and the model group received the same amount of normal saline. The behavioral changes of rats in each group were observed by open field test and forced swimming test. Left ventricular fractional shortening （LVFS） and left ventricular ejection fraction （LVEF） were measured by echocardiography. The serum levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were detected by the enzyme-labeled apparatus. Hematoxylin-eosin （HE） staining was used to observe the histomorphological changes of the heart. The serum levels of angiotensin Ⅱ （AngⅡ）， ACE2， and Ang（Ⅰ-Ⅶ） were detected by enzyme-linked immunosorbent assay （ELISA）. The protein and mRNA expression of ACE2 and MasR in the hippocampus and the heart was detected by real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultCompared with the normal group， the model group showed reduced movement time， distance， and average speed in the central area of the open field （P<0.01）， prolonged immobility time of rats in the forced swimming test （P<0.01）， decreased LVFS and LVEF （P<0.01）， inflammatory exudation and disorderly arranged fiber in heart tissues， elevated serum levels of TC， LDL-C， AngⅡ， ACE2 and Ang（Ⅰ-Ⅶ）， diminished HDL-C （P<0.01）， dwindled mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus， and up-regulated mRNA and protein expression of MasR in the heart （P<0.01）. Compared with the model group， the modified CHSG group displayed increased movement time， distance， and average speed in the center area of the open field （P<0.01）， shortened immobility time in the forced swimming test （P<0.01）， increased LVFS and LVEF （P<0.01）， relieved heart injury， reduced serum levels of TC， LDL-C， AngⅡ， ACE2， and Ang（Ⅰ-Ⅶ）， elevated level of HDL-C （P<0.01）， up-regulated mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus， and down-regulated mRNA and protein expression of MasR in the heart （P<0.01）. Each disassembled formula could improve the above indexes to a certain extent （P<0.05， P<0.01）， but the effect of the whole formula was optimal. ConclusionThe modified CHSG and its disassembled formulas have the effects of resisting depression， improving myocardial injury， and reducing blood lipid. Due to the synergistic effects of stasis-resolving/phlegm-eliminating drugs， liver-smoothing/Qi-moving drugs， and spleen-tonifying/blood-nourishing drugs in the formula， the modified CHSG is superior to each disassembled formula in efficacy. Its mechanism may be related to the activation of the ACE2-Ang （Ⅰ-Ⅶ）-MasR axis.

Objective: To translate the English version of the non-alcoholic fatty liver disease quality of life scale (CLDQ-NAFLD) into the Chinese version in order to test its reliability and validity. Methods: The English version of the CLDQ-NAFLD was translated according to the cross-cultural research tool debugging and validation guidelines to form the Chinese version of the CLDQ-NAFLD. A questionnaire survey was conducted on 515 NAFLD cases in a tertiary hospital in Hangzhou from September 2021 to April 2022 to evaluate the reliability and validity of the scale. Results: The Chinese version of the CLDQ-NAFLD contained six domains with a total of thirty-six items (X2/DF=3.105, RMSEA=0.064, TLI=0.905, CFI=0.912, and IFI=0.913). I-CVI, S-CVI/UA, and S-CVI/Ave was 0.83 to 1.00, 0.86 and 0.98, respectively. The 12-item Short-Form Health Survey (SF-12) was used as the calibration standard, and the correlation validity of the calibration standard was 0.704 (P<0.001). The Cronbach's alpha coefficient of the total scale and each dimension of the scale was 0.964 and 0.807-0.956, respectively. The test-retest reliability was 0.839. Conclusion: The Chinese version of the CLDQ-NAFLD has good reliability and validity. Thus, it can be used to evaluate the quality of life for NAFLD patients with a Chinese cultural background.

INTRODUCTION: This is a retrospective analysis of outcomes by Singapore Medical Council (SMC) disciplinary tribunals in cases involving junior doctors. We aimed to classify the types of unprofessional behaviour and consider appropriate measures for remediation and prevention. METHODS: SMC's annual reports from 1979 to 2017 and published grounds of decision from 2008 to 2017 were examined using two screening levels to identify cases involving junior doctors. Cases were sorted into five outcome categories: (a) professional misconduct; (b) fraud and dishonesty; (c) defect in character; (d) disrepute to the profession; and (e) acquitted. RESULTS: A total of 317 cases were identified, of which 13 (4.1%) involved junior doctors: 4 (30.8%) cases involved professional misconduct, 4 (30.8%) cases involved fraud and dishonesty, 3 (23.1%) cases saw an acquittal, and one case each involved defect in character and disrepute to the profession. The four cases of professional misconduct highlight the need to differentiate medical errors due to systems factors from those due to individual culpability, by applying analytical tools such as root cause analysis and Unsafe Act Algorithms. Disciplining the individual alone does not help prevent the recurrence of similar medical errors. We found that fraud and dishonesty was an important category of unprofessional behaviour among junior doctors. CONCLUSION While the frequency of unprofessional behaviour among junior doctors, as determined by the SMC disciplinary tribunal, is low (4.1%), this study highlights that complaints against medical doctors often involve systems issues and individual factors. Unprofessional behaviours related to fraud and dishonesty need special attention in medical school.

Objective:To analyze the epidemic situation and influencing factors of plague in Dehong Dai and Jingpo Autonomous prefectures (Dehong) from 1950 to 2019, for the improvement of strategies on prevention and control of the disease.Methods:The epidemic situation and surveillance data of animal and human plague in Dehong prefecture from 1950 to 2019 were collected and analyzed by descriptive epidemiological methods. Multiple linear regression equations were established by SPSS 20.0 software to analyze the relationship between plague among animals and rat density and flea index, as well as the relationship between human plague and plague among animals.Results:In Dehong prefecture, plague experienced a phenomenon of epidemic-resting-epidemic-resting cycle, between 1950 and 2019. During this period, 614 epidemic spots were identified in 36 townships of five counties/cities,. Human plague had been prevalent for 15 years, with 1 153 human cases and 379 deaths involved. Between 1982 and 2019, 261 319 rodents were captured, of which Rattus flavipectus accounted for 70.95%(185 421/261 319). A total of 70 124 fleas were seized with 76.65%(53 752/70 124), xenopsylla cheopis as fleas. The index of fleas and free fleas were 0.57 and 0.22 respectively. A total of 1 577 strains of Yersinia pestis were isolated from 285 091 animal specimens and 418 strains of Yersinia pestis were isolated from 60 119 groups of fleas, with 255 F1 antibody positive samples were detected from 64 157 sera samples. Neither Yersinia pestis nor the outbreak of plague had been noticed since 2008. Correlations between both animal plagues and rat density, as well as human plague and animals plague were noticed from the regression analysis. Conclusions:The epidemics of plague were with long-term and stable nature, in Dehong prefecture. Affected by many factors, plague seemed in a resting period currently. However, we should be reminded that the fact that outbreak of plague may revive at some uncertaint point. Hence in order to prevent human plague, strategies as careful surveillance programs on animals, need to be strenthened.
