Objective To explore and identify the nutritional/inflammatory indicator with the highest predictive potential for overall survival(OS)in postoperative tumor patients so as to provide guidance for postoperative rehabilitation of tumor patients.Methods Data from 3 191 surgical patients were collected,including 15 nutritional/inflammatory indicators.The maximum selection rank statistic method was used to calculate the optimal cut-off values for continuous indicators.The Kaplan-Meier method was used to assess OS,and Cox proportional hazards models were used to analyze the association between the aforementioned 15 indicators and survival.The predictive value of these 15 indicators was evaluated with receiver operating characteristic(ROC)curves and C-index.Results Multivariate analysis showed that all 15 indicators were significantly associated with poorer OS in surgical patients(P＜0.05 for all).Time-dependent area under the curve(AUC)and C-index analysis indicated that 3 indicators with the highest predictive potential in OS in postoperative tumor patients were the nutritional risk index(NRI)(C-index:0.597),C-reactive protein-to-albumin ratio(CAR)(C-index:0.587),and C-reactive protein-to-lymphocyte ratio(CLR)(C-index:0.587).The optimal cut-off value for NRI was determined to be 104.31(i.e.,NRI＜104.31 suggests malnutrition)with the maximum selection rank statistic method,the optimal cut-off value for CAR to be 0.05(i.e.,CAR≥0.05 suggests a strong inflammatory response,often accompanied by malnutrition),and the optimal cut-off value for CLR to be 1.18(i.e.,CLR≥1.18 suggests a strong inflammatory response).Subgroup analysis indicated that NRI,CAR,and CLR had good correlation with tumor staging,and there were significant differences between tumor node metastasis(TNM)Ⅲ/Ⅳ stage patients and TNM Ⅰ/Ⅱ stage patients when there was a strong inflammatory response or malnutrition.Conclusion In postoperative tumor patients,NRI,CLR,and CAR have high prognostic value.Combining these with the patient's clinical stage,it enables more precise guidance for clinical diagnosis and treatment strategies.

Its pathogenesis remains unclear, and may be related to genetic and environmental factors. This review summarizes progress in the treatment of anti-MDA5 antibody-positive dermatomyositis in recent years, in order to provide new ideas for its clinical treatment.

[Purpose]To evaluate the liver and kidney safety of traditional Chinese medicine(TCM)compounds in the treatment of gastric cancer.[Methods]The clinical data of gastric cancer patients who attended in Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 2012 to February 2022 were collected.The results of liver and renal func-tion tests were rated according to National Cancer Institute-Common Terminology Criteria for Ad-verse Events(NCI-CTCAE)V5.0.The patients were divided into 4 groups:TCM group,TCM+chemotherapy/targeted/antivascular therapy group,TCM+TCM preparation group and TCM+chemotherapy/targeted/antivascular therapy+TCM preparation group,and the effects of TCM on liver and renal functions were analyzed.[Results]A total of 7 943 patients were included in the analysis,of which 2 941 cases receiving TCM ≥12 months,1 468 months ≥36 months,and 687 months≥60 months.The highest incidence rate of liver function abnormality was 13.71％,the highest in-cidence rate of grade 3/4 abnormality was 2.58％;the highest incidence of creatinine abnormality was 2.32％,the highest incidence rate of grade 3/4 abnormality was 0.37％in patients with differ-ent duration of taking TCM.Most of liver and renal function abnormalities occurred in the early stage of drug taking.The incidence of liver and renal function abnormalities in the TCM group was lower than that of the other three groups.The incidence of grade 3/4 abnormality for direct biliru-bin(DBIL)in the TCM group was 0.14％,for aspartate transaminase(AST)was 0.11％,for alka-line phosphatase(ALP)was 0.16％,for alanine aminotransferase(ALT)was 0.06％and for total bilirubin(TBIL)was 0.07％,and there was no grade 3/4 creatinine abnormality observed.The ab-normal liver and renal function indexes were not increased with the increase of the length of herbal medicine taking.[Conclusion]The study shows that long term taking TCM drugs and stan-dardized prescriptions for gastric cancer patients are safe.

ObjectiveTo investigate the impacts of three types of acupuncture timing factors， including intervention initiation time， needle retention duration， and treatment intervals， on the treatment efficacy of ischemic stroke （IS） and provide evidence-based support for optimizing acupuncture timing strategies. MethodsA systematic search was conducted in both Chinese and English databases， including CNKI， Wanfang Data， VIP， CBM， PubMed， Web of Science， Cochrane Library， and Embase. The randomized controlled trials involving multiple acupuncture intervention time groups were included to reduce inter-study heterogeneity. A network meta-analysis model was constructed to compare the effects of different intervention initiation time， needle retention duration， and treatment intervals on primary IS outcomes， including total clinical response rate， neurological and limb function scores， quality of life score， and hemorheological parameters. Adverse events were also assessed. ResultsA total of 32 studies were included. The results showed that early acupuncture intervention （1-3 days and 4-7 days after onset） outperformed late intervention （>14 days） in terms of response rate， neurological function improvement， and quality of life （P<0.05， P<0.01）. Extending needle retention time to 40-60 min was associated with improved response rates and hemorheological parameters （P<0.01）. No significant differences were observed among different treatment intervals. The evidence of key outcomes showed high overall certainty， with low heterogeneity and inconsistency. Sensitivity analyses and publication bias assessments indicated the stability of the main results and a low risk of publication bias. No significant adverse reaction was reported. ConclusionDifferent timing factors significantly influence the efficacy of acupuncture treatment for IS. Early intervention and appropriately extended needle retention time result in better clinical outcomes， while treatment interval has no significant effect on efficacy. The inclusion of studies with multiple acupuncture timing groups helps control methodological heterogeneity and enhances the robustness of the analysis， providing evidence-based guidance for optimizing acupuncture timing strategies in IS management.

ObjectiveTo construct a comprehensive evaluation indicator system for clinical practice guidelines of traditional Chinese medicine （TCM） that is scientific， systematic， and reflects the characteristics of TCM. MethodsA systematic search was conducted in Chinese and English databases， including CNKI， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library， to include literature on domestic and international guideline evaluation tools and TCM-related research. Document analysis and CiteSpace were utilized for keyword co-occurrence and clustering analysis. ResultsA total of 65 relevant studies were included， from which seven core thematic domains were identified. Based on the research objectives， a two-step construction strategy was adopted： first， an external evaluation framework was established by referencing international tools to cover methodological rigor and procedural standardization； second， an internal evaluation framework was developed to reflect the distinctive features of TCM clinical practice， including syndrome differentiation and efficacy feedback. Through expert consensus， the indicator system was refined， resulting in a dual-layered structure comprising 8 primary indicators， 22 secondary indicators， and 62 evaluation criteria. ConclusionThe comprehensive evaluation system for TCM clinical practice guidelines， based on bibliometric analysis and core element extraction， integrates both theoretical integrity and practical applicability. This study provides a preliminary research foundation for further optimization， validation， and development of a refined comprehensive evaluation system.

Objective:To analyze the relationship between blood urea nitrogen (BUN)/albumin (ALB) ratio (B/A) and prognosis of patients undergoing percutaneous coronary intervention (PCI) guided by ultrasound before operation.Methods:A total of 116 patients who underwent PCI under the guidance of intra-coronary ultrasound in Xianyang Central Hospital from February 2020 to December 2022 were retrospectively selected as the observation group, and 120 healthy people in the same period were selected as the control group. All patients were followed up for 1 year after surgery, and 116 patients were divided into poor prognosis group ( n=33) and good prognosis group ( n=83), taking major adverse cardiovascular events (MACE) as the end point during follow-up. The levels of BUN and ALB in peripheral blood of all subjects were detected after admission, and B/A was calculated. The basic data, biochemical indexes and B/A of each group were analyzed and compared. The predictive value of preoperative BUN, ALB and B/A on postoperative MACE in patients with PCI guided by intra-coronary ultrasound was analyzed by receiver operating characteristic (ROC) curve. Multivariate logistic regression analysis was used to evaluate the related influencing factors of postoperative MACE in patients with PCI guided by intra-coronary ultrasound. Results:The left ventricular end-diastolic inner diameter (LVEDD), N-terminal B-type natriuretic peptide (NT-proBNP), creatine kinase isoenzyme (CK-MB), BUN and B/A in the observation group were higher than those in the control group, and left ventricular ejection fraction (LVEF) and ALB were lower than those in the control group (all P<0.05). NT-proBNP, CK-MB, BUN and B/A in the poor prognosis group were higher than those in the good prognosis group, and LVEF and ALB were lower than those in the good prognosis group (all P<0.05). ROC curve results showed that the AUC of peripheral blood BUN, ALB and B/A predicting postoperative MACE in patients with PCI guided by intra-coronary ultrasound were 0.833(95% CI: 0.783-0.883), 0.859(95% CI: 0.809-0.909) and 0.922(95% CI: 0.872-0.972). Multivariate logistic regression analysis showed that LVEF [ OR(95% CI)=1.952(1.317-2.895)], NT-proBNP [ OR(95% CI)=2.625(1.643-4.193)], BUN [ OR(95% CI)=3.353(1.922-5.851)], ALB [ OR(95% CI)=3.792(2.049-7.018)] and B/A [ OR(95% CI)=3.277(2.000-5.370)] were all the influencing factors of postoperative MACE in patients undergoing PCI guided by intra-coronary ultrasound ( P<0.05). Conclusions:The level of B/A in patients with PCI guided by intra-coronary ultrasound increased before surgery, and the high level of B/A is a risk factor for postoperative MACE, which can be used as a biological index to evaluate the postoperative MACE in patients with PCI guided by intra-coronary ultrasound.
