BACKGROUND: Over 65 million people have long COVID. Evidence for using Chinese herbal medicine (CHM) to treat long COVID is growing. A systematic review of evidence for guiding clinical decision is warranted. OBJECTIVE: To examine the effects and safety of CHM in alleviating the severity of dyspnea, fatigue, exercise intolerance, depression, anxiety and insomnia in long COVID adults based on registered randomized clinical trials (RCT). SEARCH STRATEGY: World Health Organization International Clinical Trials Registry Platform and Chinese Clinical Trial Registry were searched for registered trial protocols from database inception to February 10, 2023. English (PubMed, Embase, AMED and CINAHL) and Chinese databases (CNKI, Wanfang Data and CQVIP) were then searched to identify relevant publications from December 2019 through April 6, 2023. INCLUSION CRITERIA: Registered RCTs that compared the effects of Chinese herbal medicines or Chinese herbal formulas against a control treatment (i.e., the placebo or usual care) in adults with persistent symptoms of long COVID. The primary outcome of dyspnea, and secondary outcomes of fatigue, exercise intolerance, depression, anxiety and insomnia were measured using validated tools at the end of the treatment. DATA EXTRACTION AND ANALYSIS: Data were extracted, and eligible RCTs were evaluated using version 2 of the Cochrane risk-of-bias tool for randomized trials and Grading of Recommendations, Assessment, Development and Evaluations independently by two researchers. Effect sizes were estimated by random-effects modelling and mean difference (MD). Heterogeneity between trials was quantified by I². RESULTS: Among the 38 registered clinical trials we identified, seven RCTs (1,519 patients) were included in the systematic review. One RCT had a low overall risk of bias. Compared to the control, CHM reduces dyspnea on the Borg Dyspnea Scale score (MD = -0.2, 95% confidence interval [CI] = -0.65 to 0.25) with moderate certainty, and reduces fatigue on the Borg Scale (MD = -0.48, 95% CI = -0.74 to -0.22) with low certainty. CHM clinically reduces depression on Hamilton Depression Rating Scale score (MD = -6.00, 95% CI = -7.56 to -4.44) and anxiety on Hamilton Anxiety Rating Scale score (MD = -6.10, 95% CI = -7.67 to -4.53), and reduces insomnia on the Insomnia Severity Index (MD = -4.86, 95% CI = -12.50 to 2.79) with moderate certainty. Meta-analysis of two RCTs (517 patients) showed that CHM clinically improves exercise intolerance by increasing 6-minute walking distance (MD = -15.92, 95% CI = -10.20 to 42.05) with substantial heterogeneity (I² = 68%) and low certainty. CONCLUSION CHM is associated with a post-treatment clinical reduction in depression and anxiety in long COVID adults, compared to the control, but it does not have a strong treatment effect on dyspnea and insomnia. Effects of CHM on exercise intolerance and fatigue are uncertain, and the safety of using CHM remains questionable. Please cite this article as: Tsang MS, Zhou IW, Zhang AL, Xue CC.

Central venous lesion represents one of the common complications affecting vascular access in hemodialysis patients, potentially compromising hemodialysis efficacy. The management of symptomatic central venous lesion remains a critical challenge in clinical practice. Current primary treatment strategies include percutaneous transluminal angioplasty and percutaneous transluminal stenting. Advances in techniques such as sharp recanalization and the mother-child platform approach, along with the development of high-pressure balloons, paclitaxel- coated balloons, and covered stents, have significantly improved procedural success rates. However, unresolved issues persist, including standardized treatment protocols, technical considerations for lesion traversal, and optimal stent selection criteria. This article comprehensively reviews the treatment principles, lesion passage techniques, treatment techniques, and recent advancements of central venous lesion.

Objective Exploring the diagnostic value of T-cell enzyme-linked immunospot assay(T-SPOT.TB)combined with rifampicin-resistant Mycobacterium tuberculosis real-time fluorescence quantitative nucleic acid ampli-fication detection(XpertMTB/RIF)in geriatric AIDS patients with Mycobacterium tuberculosis(MTB)infection.Methods From May 2022 to May 2024,86 elderly patients with AIDS suspected MTB in Hengshui Third People's Hospital were gathered and separated into AIDS complicated with MTB(research group)and AIDS without MTB(control group)according to the pathological examination results.MTB culture,T-SPOT.TB and XpertMTB/RIF were performed.Kappa analysis was applied to evaluate the consistency between T-SPOT.TB combined with Xpert-MTB/RIF and the gold standard for diagnosing MTB coinfection in AIDS patients.ROC curve and four grid table were plotted to analyze the value of the combination of T-SPOT.TB and XpertMTB/RIF in the diagnosis of AIDS complicated with MTB infection.Results The blood γ-interferon,the positive detection rates of T-SPOT.TB and XpertMTB/RIF in the research group were higher than those in the control group(P＜0.05).The AUC of T-SPOT.TB in diagnosing AIDS with MTB infection was 0.810,that of Xpert MTB/RIF in diagnosing AIDS with MTB infection was 0.835,and the AUC of the two in diagnosing AIDS with MTB infection was 0.910.The Kappa values of T-SPOT.TB,Xpert MTB/RIF and their combined diagnosis for AIDS with MTB infection were 0.624,0.674 and 0.825,respectively.The accuracy of T-SPOT.TB in the diagnosis of AIDS with MTB was 82.56%,the accuracy of XpertMTB/RIF in the diagnosis of AIDS with MTB was 84.88%,and the accuracy of the combined di-agnosis for AIDS with MTB was 91.86%.Conclusions T-SPOT.TB combined with XpertMTB/RIF can improve the accuracy of diagnosis of AIDS with MTB,and can be used as a clinical auxiliary diagnosis method for AIDS pa-tients complicated with MTB.

Chinese medicine has been used for centuries to treat a range of health conditions.This history has produced a wealth of classical literature,case studies and clinical research data detailing its use and effectiveness.However,high-quality and conclusive evidence that meets modern requirements for clinical decision support is lacking.This evidence gap limits the integration of Chinese medicine with contemporary medicine,which in turn limits global access and acceptance of Chinese medicine as a form of safe and effective health care.Over the past 20 years,researchers and organisations around the world,including the World Health Organization(WHO)and United Nations,have worked to support the integration of traditional medicines,such as Chinese medicine,with conventional medicines to improve global health care.This paper provides an overview of Chinese medicine studies published in the top four general medical journals(BMJ,JAMA,Lancet and New England Journal of Medicine)from February 2005 to February 2024 in the past 20 years to highlight the progress in the development of this evidence base.It also highlights key actions taken to promote evidence-based clinical Chinese medicine,including product and practitioner regulation,formalising education standards,and international collaborations.Research conducted at the China-Australia International Research Centre for Chinese Medicine demonstrates the benefits of such a collaboration.Through development of its unique and inclusive'whole-evidence'approach,plus clinical studies and systematic reviews,the Centre has significantly contributed to the evidence base for clinical Chinese medicine.In addition,its high-impact papers and groundbreaking monographs have been cited in international conventional medicine guidelines.While progress has certainly been made during the past 20 years to build a stronger evidence base for clinical Chinese medicine,there is still a considerable gap that limits its integration with conventional medicine.Future funding and research are needed to continue this work and achieve to safe,effective and accessible traditional medicine as part of the WHO's Universal Health Coverage strategy.

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.

This study retrospectively analyzed the clinical data of 1 case of spermatic cord leiomyosarcoma admitted to the urology department of the Affiliated Hospital of Chengde Medical College. The clinical characteristics, diagnosis, treatment and prognosis was discussed with the literature review. Radical resection of the left testicle and high ligation of the left spermatic cord were performed. Postoperative pathology was spermatic cord leiomyosarcoma. Its clinical manifestations are painless masses, which are mainly confirmed by pathological examination. The treatment is mainly radical resection, and postoperative radiotherapy can improve the prognosis and reduce recurrence.

OBJECTIVE: To compare 3 commonly used methods for drug delivery via the lumbar spinal subarachnoid space in rats. METHODS: We compared the effects of 3 methods for drug delivery via the lumbar spinal subarachnoid space in Sprague Dawley rats, namely acute needle puncture, chronic catheterization via laminectomy, and non-laminectomized catheterization. Body weight changes of the rats were measured, and their general and neurological conditions were assessed after the surgeries. The motor function of the rats was examined using rota rod test both before and after the surgeries. Nociceptive tests were performed to assess nociception of the rats. HE staining was used to examine local inflammation caused by the surgeries in the lumbar spinal cord tissue, and lidocaine paralysis detection and toluidine blue dye assay were used to confirm the precision of drug delivery using the 3 methods. RESULTS: Both needle puncture and catheterization via laminectomy resulted in a relatively low success rate of surgery and caused neurological abnormalities, severe motor dysfunction, hyperalgesia, allodynia and local inflammation. Catheterization without laminectomy had the highest success rate of surgery, and induced only mild agitation, slight cerebral spinal fluid leakage, mild sensory and motor abnormalities, and minimum pathology in the lumbar spinal cord. Catheterization without laminectomy produced less detectable effects on the behaviors in the rats and was well tolerated compared to the other two methods with also higher precision of drug delivery. CONCLUSIONS Catheterization without laminectomy is a safe, accurate and effective approach to lumbar drug delivery in rats.

Objective: To investigate the expression of fragile-site associated tumor suppressor (FATS) in non-small cell lung cancer and its relationship with clinicopathological features and prognosis. Methods: A total of 140 non-small cell lung cancer (NSCLC) cases and 30 adjacent normal tissues were used to detect the expression level of FATS protein, and to analyze the relationship of FATS protein expression and clinicopathological features and prognosis of NSCLC. Results: Western blot showed that the expression of FATS in adjacent normal tissues was significantly higher than that in non-small cell lung cancer tissues. The results of immunohistochemistry showed that the high expression rate of FATS in 140 cases of NSCLC was 40.0%, and the high expression rate of FATS in 30 cases of adjacent tissues was 73.3%. The difference was statistically significant (P=0.01). Further analysis showed that the TNM stage (P=0.044) and lymph node metastasis (P=0.022) were significant difference between FATS high expression group and low expression group. The 6-year overall survival (OS) rates of NSCLC patients with FATS high-expression and low-expression were 57.1% and 23.8%, respectively, and the 6-year disease-free survival (DFS) rates were 53.6% and 21.4%, respectively, with statistically significant differences (P=0.001). In Cox multivariate analysis, we found gender (HR=1.658, P=0.028; HR=1.684, P=0.023), TNM staging (HR=2.327, P=0.019; HR=2.332, P=0.013) and FATS expression (HR=0.532, P=0.010; HR=0.538, P=0.009) were independent prognostic factors for both OS and DFS of NSCLC patients. Conclusions The expression of FATS protein is associated with the development and is an independent prognostic factor of NSCLC patients. The detection of FATS protein is expected to be a new biomarker for evaluating the prognosis of NSCLC patients.

Objective:To investigate the clinical characteristics of idiopathic hypereosinophilic syndrome (IHES) with gastrointestinal manifestations,and to improve the level of diagnosis and treatment of IHES. Methods:The clinical materials, process of diagnosis and treatment and prognosis of 9 patients diagnosed as IHES with gastrointestinal manifestations were retrospectively analyzed. Results:The average age of 9 patients was (22.66± 12.86)years old,and the ratio of male and female was about 1.25∶ 1. The main clinical manifestations included abdominal pain,diarrhea and abdominal distension.The eosinophil percentages in peripheral blood and bone marrow of the patients were (42.66 ± 19.88 )% and (39.33 + 15.99 )%, respectively.The ascites exudate cytology examination showed eosinophil infiltrated.The results of gastroscope or colonoscope showed mucosal hyperemia and edema,scattered bleeding spots, and dark red granular hyperplasia; the colon was affected frecuently.The histological biopsy confirmed that the mucosal was infiltrated by eosinophils.The abdominal CT of 6 patients showed that the walls of stomach or bowel were thickened.The abdominal symptoms disappeared,and the ascites was absorpted in 9 patients after the treatment of glucocorticoid.After 2 years of follow up,2 patients had relapse, others had no recurrence.Conclusion:Performing the routine diagnosis and treatment of gastrointestinal diseases, the clinicians should consider the possibility of IHES in order to avoid the misdiagnosis and delayed treatment. When IHES is diagnosed,steroid treatment should be performed in preference.
