ObjectiveTo investigate the recurrence of ischemic stroke (IS) and to analyze the association between four indices of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and the risk of IS recurrence by analyzing the follow-up data related to IS in the community-based natural population of Songjiang District, Shanghai, so as to provide a scientific basis for improving the prognosis of stroke patients in the community and controlling IS recurrence. MethodsA prospective follow-up study was conducted among the IS patients in the community-based cohort population, collecting data about patient’s age, gender, disease history, biochemical indicators, and etc. Cox regression model and restricted cubic spline model were used to analyze the relationship between different levels of plasma lipids and the recurrence of IS in these patients. ResultsA total of 1 368 patients with IS were included. The total follow-up duration was 7 171.46 person-years, with a median follow-up time of 6.24 years. There were 420 cases of IS recurrence, resulting in a cumulative recurrence rate of 30.70%. The results of multivariate Cox regression analysis showed that the recurrence risk of IS was reduced when the baseline TC and LDL-C levels of IS patients were in the ranges of 4.65‒5.67 mmol·L^-1 and 2.52‒3.46 mmol·L^-1, respectively. The results of restricted cubic spline analysis showed a U-shaped relationship between baseline TC and LDL-C levels and the recurrence risk in IS patients. ConclusionThe cumulative recurrence rate of patients with IS in the community of Songjiang District in Shanghai is high, and the levels of TC and LDL-C at baseline survey are correlated with the recurrence of IS in these patients. It is suggested to pay more attention to the levels of LDL-C and TC in patients with IS, so as to improve the prognosis.

Ehlers-Danlos syndromes (EDS) are a group of rare hereditary connective tissue disorders characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Short stature is defined as a height that is two standard deviations or more below the average height for individuals of the same age, sex, and race. The etiopathogenesis of short stature is complicated. Early detection and appropriate intervention are essential in disease treatment. However, short stature is not common among all EDS subtypes. It is frequently observed in patients with rare subtypes, such as spondylodysplastic EDS, dermatosparaxis EDS, and musculo-contractural EDS. Besides, height may be affected by other factors including spinal curvature and malnutrition. Deep phenotyping and multidisciplinary team approaches are recommended for the diagnosis and management. Short stature in patients with EDS has not been sufficiently acknowledged in China. There is currently a lack of high-level evidence for the treatment of EDS-related short stature. Therefore, this review aims to present recent progress of diagnosis and management of short stature in patients with EDS. Further studies focusing on short stature in rare subtypes are necessary to advance precision medicine and enhance patient care.

Objective:To explore the incidence of chronic obstructive pulmonary disease (COPD) in a cohort aged 40 years and above in Songjiang District, Shanghai, and to analyze the association of Mediterranean diet pattern and dietary approaches in stopping hypertension pattern (DASH) with the risk of developing COPD.Methods:Based on a natural population cohort in Songjiang District, Shanghai, 27 474 adults aged 40 years and above who did not have COPD at baseline were enrolled in the study. The Cox proportional risk regression model was used to analyze the association of baseline Mediterranean diet pattern score and DASH score with the risk of COPD, and the hazard ratio ( HR) of the risk and its 95% CI were calculated. Restricted cubic spline was used to analyze the nonlinear association between the two diet scores and the risk of COPD. Stratified analyses were performed according to gender, age, smoking status, etcetera. Sensitivity analyses were conducted by censoring cases diagnosed within one year after the baseline survey or people with a history of malignant tumor disease. Results:As of June 30, 2023, after a median follow-up time of 6.21 years, there were 1 089 (4.0%) new COPD cases with an incidence density of 64.00 per 10 000 person-years. After adjusting for relevant confounders, in the Mediterranean tertile subgroups under diet pattern score, the risk of developing COPD could be reduced by approximately 14% in the intermediate scoring group ( HR=0.86, 95% CI: 0.75-0.99) and 15% in the highest scoring group ( HR=0.85, 95% CI: 0.72-0.99) compared to the lowest scoring group. The association remained after censoring cases diagnosed within one year of the baseline survey ( HR=0.82, 95% CI: 0.70-0.95; HR=0.82, 95% CI: 0.68-0.97) or censoring people with a history of malignant tumor disease ( HR=0.84, 95% CI: 0.73-0.97; HR=0.84, 95% CI: 0.71-0.99). No statistical association was found between the DASH score and the risk of COPD. Conclusions:The Mediterranean diet pattern was associated with a lower risk of COPD. Increasing the intake of vegetables, fruits, legumes, and whole grains and decreasing the intake of red meat and others can reduce the risk of COPD. No association was found between the DASH dietary pattern and the risk of COPD in this community population.

Hepatocellular carcinoma (HCC) is one of the most common malignancies and is a major cause of cancer-related mortalities worldwide (Forner et al., 2018; He et al., 2023). Sarcopenia is a syndrome characterized by an accelerated loss of skeletal muscle (SM) mass that may be age-related or the result of malnutrition in cancer patients (Cruz-Jentoft and Sayer, 2019). Preoperative sarcopenia in HCC patients treated with hepatectomy or liver transplantation is an independent risk factor for poor survival (Voron et al., 2015; van Vugt et al., 2016). Previous studies have used various criteria to define sarcopenia, including muscle area and density. However, the lack of standardized diagnostic methods for sarcopenia limits their clinical use. In 2018, the European Working Group on Sarcopenia in Older People (EWGSOP) renewed a consensus on the definition of sarcopenia: low muscle strength, loss of muscle quantity, and poor physical performance (Cruz-Jentoft et al., 2019). Radiological imaging-based measurement of muscle quantity or mass is most commonly used to evaluate the degree of sarcopenia. The gold standard is to measure the SM and/or psoas muscle (PM) area using abdominal computed tomography (CT) at the third lumbar vertebra (L3), as it is linearly correlated to whole-body SM mass (van Vugt et al., 2016). According to a "North American Expert Opinion Statement on Sarcopenia," SM index (SMI) is the preferred measure of sarcopenia (Carey et al., 2019). The variability between morphometric muscle indexes revealed that they have different clinical relevance and are generally not applicable to broader populations (Esser et al., 2019).

In order to promote the innovative application of Sanjiao theory and Yingwei theory， this paper tries to apply the ''Sanjiao-Yingwei'' Qi transformation theory to the treatment of tumor diseases， integrating it with T cell exhaustion mechanism to elaborate on its scientific connotation and using network pharmacology and bioinformatics to elucidate the correlation between the anti-tumor mechanism of ''Sanjiao-Yingwei'' Qi transformation and T cell exhaustion. The ''Sanjiao-Yingwei'' Qi transformation function is closely related to the immunometabolic ability of the human body， and the ''Sanjiao-Yingwei'' Qi transformation system constitutes the immunometabolic exchange system within and outside the cellular environment. Cancer toxicity is generated by the fuzzy Sanjiao Qi， and the long-term fuzzy Sanjiao Qi is the primary factor leading to T cell exhaustion， which is related to the long-term activation of T cell receptors by the high tumor antigen load in the tumor microenvironment. Qi transformation malfunction of the Sanjiao produces phlegm and collects stasis， which contributes to T cell exhaustion and is correlated with nutrient deprivation， lipid accumulation， and high lactate levels in the immunosuppressed tumor microenvironment， as well as with the release of transforming growth factor-β and upregulated expression of programmed death receptor-1 by tumor-associated fibroblasts and platelets in the tumor microenvironment. Ying and Wei damage due to Sanjiao Qi transformation malfunction is similar to the abnormal manifestations such as progressive loss of exhausted T cell effector function and disturbance of cellular energy metabolism. Guizhi decoction， Shengming decoction， and Wendan decoction can correct T cell exhaustion and exert anti-tumor effects through multi-target and multi-pathways by regulating ''Sanjiao-Yingwei'' Qi transformation， and hypoxia inducible factor-1α （HIF-1α） may be one of the main pathways to correct T cell exhaustion. It was found that HIF-1α may be one of the important prognostic indicators in common tumors by bioinformatics. The use of the ''Sanjiao-Yingwei'' Qi transformation method may play an important part in improving the prognosis of tumor patients in clinical practice.

OBJECTIVE To estimate the cost-utility of sacituzumab govitecan （SG） versus single-agent chemotherapy in the treatment of hormone receptor-positive （HR+）/human epidermal growth factor receptor 2-negative （HER2－） advanced metastatic breast cancer. METHODS From the perspective of the Chinese medical system， a three-state partitioned survival model was constructed to examine the cost-utility of SG versus single-agent chemotherapy based on TROPiCS-02 trial. The cycle length was set to 1 month， and the time horizon was 10 years. The annual discount was 5%. The model output included total costs and quality adjusted life month （QALM）， and incremental cost-effectiveness ratio （ICER） was calculated for cost-utility analysis， by setting willingness-to-pay （WTP） threshold at 3 times gross domestic product （GDP） per capita of China in 2023 （22 340 yuan/QALM）. Univariate sensitivity analyses， probability sensitivity analyses， and scenario analyses were performed to evaluate the robustness of the results and calculate the price threshold when SG had economic advantages. RESULTS SG group gained incremental 4.25 QALM and 561 570 yuan compared with single-agent chemotherapy， which resulted in an ICER of 132 102/QALM that was higher than WTP. The results of the univariate sensitivity analysis showed that the monthly average cost of SG had the greatest impact on the results； the results of probability sensitivity analysis showed that the probability of SG scheme being cost-effective at the WTP threshold was 0. The results of scenario analysis showed that the conclusions of this study were robust under different time horizons （5， 10， 15 years）. The price threshold for SG being cost-effective was 1 344 yuan per 180 mg. CONCLUSIONS Based on the perspective of Chinese medical system， SG appears to be not cost-effective compared with single-agent chemotherapy for HR+/ HER2－ advanced metastatic breast cancer at the price of 8 400 yuan per 180 mg. A substantial price cut should be taken to be cost- effective.

Integrating evidence from animal experiments is a critical component of biomedical research, providing essential prior information for in-depth investigations of disease mechanisms and new drug development. Animal models have played an irreplaceable role in simulating human diseases. However, the integration of evidence from animal experiments has faced numerous challenges, including insufficient emphasis, significant heterogeneity in study designs, high publication bias, and discrepancies with clinical research practices. This paper first identifies existing issues in the original research evidence from animal experiments, such as the selection and applicability of animal models, considerations in the design of experimental studies, and factors influencing the translation of animal experimental evidence. It then discusses various methods for integrating this evidence, including systematic review and meta-analysis, overview of systematic review/umbrella review, scoping review, and evidence mapping, while highlighting recent advancements in their application. Finally, the paper addresses the main challenges currently encountered in the integration of evidence from animal experiments and proposes targeted improvement strategies aimed at enhancing the efficiency of translating research outcomes into clinical practice and promoting the advancement of evidence-based medicine. By continuously optimizing original experimental research protocols and evidence integration practices, this work aims to establish a more efficient and scientific environment for the synthesis of evidence from animal experiments, ultimately contributing to clinical trials and human health.

Objective To compare the effect of three-dimensional visual (3DV) model, three-dimensional printing (3DP) model and computer-aided design (CAD) modified 3DP model in video-assisted thoracoscopic surgery (VATS) sublobular resection. Methods The clinical data of patients who underwent VATS sublobular resection in the Affiliated Hospital of Hebei University from November 2021 to August 2022 were retrospectively analyzed. The patients were divided into 3 groups including a 3DV group, a 3DP group and a CAD-3DP group according to the tools used. The perioperative indexes and subjective evaluation of operators, patients and their families were compared. Results A total of 22 patients were included. There were 5 males and 17 females aged 32-77 (56.95±12.50) years. There were 9 patients in the 3DV group, 6 patients in the 3DP group, and 7 patients in the CAD-3DP group. There was no statistical difference in the operation time, intraoperative blood loss, drainage volume, hospital stay time or postoperative complications among the groups (P>0.05). Based on the subjective evaluations of 4 surgeons, the CAD-3DP group was better than the 3DV group in the preoperative planning efficiency (P=0.025), intuitiveness (P=0.045) and doctor-patient communication difficulty (P=0.034); the CAD-3DP group was also better than the 3DP group in the overall satisfaction (P=0.023), preoperative planning difficulty (P=0.046) and efficiency (P=0.014). Based on the subjective evaluations of patients and their families, the CAD-3DP group was better than the 3DP group in helping understand the vessel around the tumor (P=0.016), surgical procedure (P=0.020), procedure selection (P=0.029), and overall satisfaction (P=0.048); the CAD-3DP group was better than the 3DV group in helping understand the tumor size (P=0.038). Conclusion CAD-modified 3DP model has certain advantages in pre-planning, intraoperative navigation and doctor-patient communication in the VATS sublobectomy.

BACKGROUND:Prosthesis restricted selection,soft tissue release,patellar trajectory recovery,and bone defect reconstruction were need to be optimized in total knee arthroplasty for moderate and severe valgus knee.The medial parapatellar approach has disadvantages in the treatment of valgus knee,such as aggravating the medial soft tissue relaxation.In recent years,it has been found that the lateral parapatellar approach has advantages in the treatment of valgus knee,such as exposure and release. OBJECTIVE:To observe the efficacy of the lateral and medial parapatellar approach in total knee arthroplasty for moderate and severe valgus knee,and to explore a more suitable surgical approach for moderate and severe valgus knee. METHODS:Totally 56 patients with moderate and severe valgus knee underwent total knee arthroplasty and would take turns performing surgery through the medial and lateral parapatellar approach according to the order of admission.The lateral group(n=28)underwent total knee arthroplasty through lateral parapatellar approach,and the medial group(n=28)through medial parapatellar approach.Posterior stablized knee prosthesis was used in all patients.The restricted types of prosthesis,thickness of polyethylene,operation time,amount of blood loss,femoro-tibia angle,patellar tilt angle,range of motion,Hospital for Special Surgery score,Western Ontario and McMaster Universities Arthritis Index(WOMAC)score,and complications were collected as observation indexes for statistical analysis. RESULTS AND CONCLUSION:(1)The utilization rate of condyle-restricted prosthesis in the lateral group was significantly lower than that in the medial group.The average thickness of polyethylene liner was lower,and the operation time was shorter in the lateral group compared with the medial group.There were significant differences between the two groups(P<0.05),and there was no significant difference in the amount of surgical bleeding.(2)56 patients were followed up for an average of 2-5 years.There were no signs of prosthesis loosening or bone resorption in all patients.The average patellar tilt angle and femoral tibial angle of the lateral group were lower than those of the medial group,and the average Hospital for Special Surgery score and WOMAC score of the lateral group were higher than those of the medial group,with significant differences(P<0.05).There was no significant difference in the range of motion of the knees between the two groups.(3)Incision fat liquefaction and calf intermuscular venous thrombosis occurred in one case in each group.No infection,poor incision healing,incisional hematoma,prosthesis dislocation,iatrogenic nerve injury,ectopic ossification,or periprosthesis fracture occurred during follow-up.(4)In conclusion,the treatment of moderate and severe valgus knee by lateral parapatellar approach can better protect the tension of the medial soft tissue of the knee,use less condylar restrictive prostheses,and have a more friendly patellar trajectory and higher postoperative function score.
