Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

OBJECTIVES: To explore the correlation of serum tryptophan level with 90-day mortality risk in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). METHODS: This retrospective study was conducted among 108 patients with HBV-ACLF, whose survival outcomes within 90 days after diagnosis were recorded. The correlation of baseline serum tryptophan levels measured by high-performance liquid chromatography with 90-day mortality of the patients was analyzed, and the predictive value of serum tryptophan for 90-day mortality was explored. RESULTS: Within 90 days after diagnosis, 53 (29.4%) of the patients died and 127 (70.6%) survived. The deceased patients had significantly lower baseline serum tryptophan levels than the survivors (7.31±3.73 pg/mL vs 13.32±7.15 pg/mL, P<0.001). Multivariate analysis suggested that serum tryptophan level was an independent factor correlated with mortality of HBV-ACLF after adjustment for confounding variables. The patients with serum tryptophan levels below the median level (10.14 pg/mL) at admission had significantly higher 90-day mortality risks than those with higher tryptophan levels (43.3% vs 15.6%, HR: 3.157, 95% CI: 1.713-5.817), and the complication by kidney dysfunction further increased the risk to 73.3% as compared with patients with higher serum tryptophan levels with normal kidney function (15.0%; HR: 7.558, 95% CI: 3.369-16.960). Serum tryptophan levels had an area under the receiver operating characteristic curve of 0.771 (95% CI: 0.699-0.844) for predicting 90-day mortality. CONCLUSIONS Serum tryptophan level is closely correlated with the survival outcomes of patients with HBV-ACLF, and a decreased tryptophan level indicates a high 90-day mortality risk, which can be further increased by the complication by kidney dysfunction.

Objective To investigate the effects of simulated-microgravity on the osteogenic differentiation,primary cilia status,cytoskeleton structure,and the YAP(Yes-associated protein)expression in primary osteoblasts.Methods Primary osteoblasts were isolated from the skull bones of neonatal Wistar rats and cultured in random positioning machine system to simulate the cellular effects of microgravity.The calcified nodules were stained with Arlizarin to assess the cellular mineralization ability,the primary cilia and cytoskeleton were detected by immunofluorescence staining of Arl13b/γ-Tubulin and α-Tubulin,respectively,and the expression of YAP was measured by western blot.Results The cellular osteogenic differentiation were markedly suppressed after treated with simulated microgravity for 24 h,and the ciliated cells decreased from(58.44±3.65)%to(15.76±1.84)%in parallel with a decline of average cilium length from(3.19±0.51)μm to(1.59±0.46)μm.In addition,simulated microgravity induced disassembly of microtubules.Notably,simulated microgravity interfered YAP expression and the inhibition of YAP into nucleus.Furthermore,knockdown of YAP expression in osteoblasts notably reduced primary cilia expression and inhibited osteogenic differentiation.Conclusion Primary cilia is a key organelle of osteoblasts in sensing microgravity and regulating osteogenic differentiation.Interference with YAP expression and inhibition of nuclear YAP entry may play an important role in the deaggregation of primary cilia induced by microgravity.

Objective:To investigate the correlation between blood uric acid level and body composition, exercise capacity, and cardiopulmonary function in medical examination population.Methods:In this cross-sectional study, 83 individuals who underwent physical examinations at Peking University Third Hospital from June 1, 2023, to October 1, 2023, and met the inclusion criteria were included. According to whether they had hyperuricemia (HUA), the participants were divided into HUA group (53 cases) and non-HUA group (30 cases). Body composition parameters, such as body mass index and visceral fat area, were measured with a body composition analyzer. Exercise capacity indicators, including grip strength, vertical jump, back strength, and sit-and-reach test, were measured using specific monitoring devices. Cardiopulmonary function was assessed using the stair index test. The clinical characteristics of the two groups were compared with t-tests or chi-square tests, and the correlation between uric acid levels and body composition, exercise capacity, and cardiopulmonary function was analyzed. Results:The HUA group had significantly higher skeletal muscle mass, body fat mass, body mass index, and visceral fat area when compared with the non-HUA group [(31.92±5.60) vs (26.11±6.19) kg, (23.66±9.33) vs (17.19±5.00) kg, (26.53±3.68) vs (23.27±3.59) kg/m2, 91.20 (74.25, 123.90) vs 68.25 (56.25, 90.48) cm 2, respectively] (all P<0.05). The grip strength, vertical jump, and back pull strength were all lower in the HUA group [32.70 (25.25, 40.30) vs 42.35 (35.95, 48.10) kg, 30.30 (24.10, 36.48) vs 40.55 (33.06, 45.10) kg, 24.20(20.60, 32.23) vs 29.90 (25.20, 35.50) cm, 65.60 (51.75, 78.00) vs 91.00 (67.25, 111.50) kg, respectivley] (all P<0.05). The increased step index was positively correlated with reduced risk of hyperuricemia ( OR=0.875, 95% CI: 0.793-0.966) ( P<0.05). Conclusions:Blood uric acid level is correlated with cardiopulmonary function in medical examination population. Individuals with better cardiopulmonary function have a lower risk of developing HUA. However, the relationship between blood uric acid level and body composition and exercise capacity is not clear.

BACKGROUND: Cancer patterns in China are becoming similar to those in the United States (US). Comparing the recent cancer profiles, trends, and determinants in China and the US can provide useful reference data. METHODS: This study used open-source data. We used GLOBOCAN 2022 cancer estimates and United Nations population estimates to calculate cancer cases and deaths in both countries during 2024. Data on cancer incidence and mortality trends were obtained from the Surveillance, Epidemiology, and End Results (SEER) program and National Centre for Health Statistics in the US and cancer registry reports of the National Cancer Center (NCC) of China. Data from the Global Burden of Disease study (GBD) and a decomposition approach were used to estimate the contributions of four determinants to the change in cancer deaths. RESULTS: In 2024, there are an estimated 3,246,625 and 2,510,597 new cancer cases and 1,699,066 and 640,038 cancer deaths in China and the US, respectively. The highest estimated cancer cases are lung cancer in China and breast cancer in the US. The age-standardized incidence rates of lung and colorectal cancer in the US, and stomach, liver, and esophageal cancer in China have decreased, but the incidence rates of liver cancer in the US and colorectal cancer, prostate cancer in men, and cervical cancer in women in China have increased. Increases in the adult population size and population aging are main reasons for the increase in cancer deaths; case fatality rates are a main reason for the decrease in cancer deaths in both countries. CONCLUSIONS China has made progress in cancer control but lags the US. Considering the transformation in China's pattern of cancers epidemiology, it is imperative to develop stronger policies by adopting the cancer prevention and control strategies used in the US to address population aging and curb growing cancer trends.

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To evaluate the relationship between postoperative delirium(POD) and preoperative frailty in elderly patients undergoing spinal surgery.Methods:Two hundred and twenty patients of both sexes, aged ≥65 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ-Ⅳ, undergoing elective posterior lumbar decompression, bone grafting and internal fixation under general anesthesia, were selected. Frailty was measured using the FRAIL (fatigue, resistance, ambulation, illness, and loss of weight) scale on 1 day before surgery. POD was assessed twice a day within 3 days by Confusion Assessment Method. Patients were divided into POD group and non-POD group according to whether POD occurred within 3 days after surgery. Multivariate logistic regression analysis was used to identify the risk factors for POD in elderly patients undergoing spinal surgery, and the value of preoperative frailty in predicting POD was analyzed using the receiver operating characteristic curve.Results:A total of 190 patients were finally enrolled, among which 55 patients presented with frailty before surgery, and the incidence was 29.0%. Forty-six patients developed POD, and the incidence was 24.2%. Multivariate logistic regression analysis showed that aging ( OR=1.15, 95% confidence interval [ CI] 1.03-1.29, P=0.017), preoperative frailty ( OR=2.35, 95% CI 1.24-4.43, P=0.009), increase in surgical segments ( OR=4.14, 95% CI 1.71-10.05, P=0.002) and increase in postoperative 24-h pain VAS score ( OR=1.38, 95% CI 1.07-1.78, P=0.013) were independent risk factors for POD in elderly patients undergoing spinal surgery. The area under receiver operating characteristic curve of preoperative frailty in predicting POD was 0.702 (95% CI 0.608-0.796, P<0.001). Conclusions:Preoperative frailty is an independent risk factor for POD in elderly patients undergoing spinal surgery. Preoperative frailty can predict the occurrence of POD in elderly patients undergoing spinal surgery to some extent.

Objective:To investigate the regulatory role of defferentially expressed LOC107987438 in the pathogenesis of depressive disorder and provide a theoretical basis for its clinical application in depressive disorder.Methods:Differential expression of LOC107987438 was verified by quantitative real-time polymerase chain reaction(qRT-PCR)in peripheral blood monocular cells(PBMCs)of 60 patients with depressive disorder and 60 health controls. In addition, its diagnostic value was assessed by receiver operating characteristic(ROC)curves. Based on the ceRNA mechanism of lncRNA, the miRDB database was applied to predict the target miRNAs of LOC107987438, and the miRNAs with target score ≥ 80 among them were screened out.The screened miRNAs were then used to predict their potential target mRNAs through four databases which were TargetScan 8.0, miRTarBase, mirDIP and miRPathDB. Moreover, the predicted target mRNAs were annotated for gene ontology(GO)function annotation and tokoyo encyclopedia of genes and genomes(KEGG) pathway enrichment analysis via ClusterProfiler 4.0.5 package of R 4.1.1. Finally, a protein-protein interaction network was constructed using the STRING 11.5 platform to retrieve the interacting genes.Results:The qRT-PCR results showed that normalized expression of LOC107987438 in PBMCs of patients with depressive disorder was higher than that in health controls(depressive disorder: 2.084±1.357, health controls: 1.000±0.660, P<0.001). The ROC curve results showed that the area under curves(AUC)of LOC107987438 was 0.759(95% CI: 0.675-0.842, P<0.05), indicating its high potential diagnostic value. Bioinformatics analysis showed that hsa-miR-4670-3p, hsa-miR-619-3p, hsa-miR-6721-5p and hsa-miR-297 were the miRNAs with high bindings to LOC107987438. The results of KEGG signaling pathway enrichment revealed that hypoxia-inducible factor 1(HIF-1)signaling pathway, phosphatidylinositol 3-kinase-AKT(PI3K-Akt) signaling pathway and erythroblastic oncogene B(ErbB) signaling pathway were closely associated with depressive disorder. Among the top ten key genes screened by the protein-protein interaction network, kirsten rats arcomaviral oncogene homolog(KRAS), androgen receptor(AR), cyclic-AMP response binding protein1(CREB1), insulin-like growth factor 1(IGF1), cyclin-dependent kinase inhibitor 1B(CDKN1B) and calcium/calmodulin-dependent protein kinase type Ⅱ alpha(CAMK2A)were strongly associated with depressive disorder. Conclusion:The establishment of ceRNA regulatory network of LOC107987438 provides a theoretical basis for exploring the pathophysiology of depressive disorders.
