Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

T cells play central roles in anti-tumor immune responses. Immune checkpoint therapy, which is based on modulation of T cell reactivity, has achieved breakthrough in clinical treatment of multiple tumors. Moreover, adoptive T cell therapy, which includes mainly genetically engineered T cells, has shown substantial treatment efficacy in hematoma. Immune therapy has tremendously changed the scenario of clinical tumor treatment and become critical strategies for treating multiple tumors. T cell receptor (TCR) is the fundamental molecule responsible for the specificity of T cell recognition. TCRs could recognize peptides, which are derived from intracellular or extracellular tumor antigens, presented by major histocompatibility complex (MHC) and are therefore highly sensitive to low antigen level. Thereby, TCRs are broadly recognized as promising molecules for the development of anti-tumor drugs. The approval of the first TCR drug in 2022 has initiated a new era for TCR-based therapeutics and since then, multiple TCR drugs have shown substantial treatment efficacy in multiple tumors. This review summarizes the progress of TCR-based immune therapeutic strategies, including T cell receptor-engineered T cell (TCR-T), TCR-based protein drugs, and other cell therapies based on TCR signaling, providing useful information for future design of immune therapeutics based on TCR.

OBJECTIVE: To explore influence of external factors of wind, cold and dampness on clinical symptoms in knee osteoarthritis (KOA) patients with different constitutions of traditional Chinese medicine. METHODS: A cross-sectional stratified study was performed to select 108 patients with GradeⅡKOA in Kellgren & Lawrence (K-L) classification, including 22 males and 86 females, aged from 47 to 75 years old with an average of (60.7±6.0) years old;body mass index(BMI) ranged from 17.87 to 31.22 kg·m^-2 with an average of (23.80±2.86) kg·m^-2. According to Classification and Judgment of TCM Physique (ZYYXH/T157-2009), the types of TCM physique were determined and divided into 4 layers according to the deficiency and actual physique. Among them, there were 24 patients without biased physique, 12 males and 12 females, aged from 51 to 73 years old with an average of(62.8±6.0) years old, BMI ranged from 17.87 to 31.14 kg·m^-2 with an average of (24.32±3.25) kg·m-2;there were 46 patients with virtual bias constitution, including 7 males and 39 females, aged from 47 to 70 years old with an average of (60.0±5.8) years old, BMI ranged from 19.38 to 31.22 kg·m^-2 with an average of(23.42±2.97) kg·m^-2;There were 26 patients with solid bias constitution, including 2 males and 24 females, aged from 48 to 75 years old with an average of (60.4±5.8) years old, BMI ranged from 21.16 to 30.76 kg·m^-2 with an average of (24.15±2.33) kg·m^-2;there were 9 patients with special constitution, 1 male and 8 female, aged from 53 to 75 years old with an average of (59.8±7.5) years old, BMI ranged from 19.26 to 26.67 kg·m^-2 with an average of (23.79±2.49) kg·m^-2. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to evaluate severity of clinical symptoms. The wind-cold-dampness external factor score was calculated through the questionnaire of wind-cold-dampness syndrome scale to evaluate degree of influence of wind-cold-dampness external factor. Pearson correlation analysis and partial correlation analysis were used to calculate the correlation coefficient between severity of external factors affecting wind, cold and dampness and severity of clinical symptoms in patients with different TCM constitution stratification. RESULTS: There was no statistical significance between total score of wind-cold-dampness and WOMAC score in patients with no biased constitution and special condition. Total wind-cold-dampness score of patients with virtual biased constitution was positively correlated with WOMAC stiffness score (r=0.327, P=0.032), and total wind-cold-dampness score of patients with solid biased constitution was positively correlated with WOMAC pain score (r=0.561, P=0.005) and WOMAC overall score (r=0.446, P=0.033). After further adjusting for the interaction of external factors of wind-cold-dampness, there was no statistical significance between wind-cold-dampness scores and WOMAC scores in patients with solid biased constitution. The score of dampness and pathogenic factors was positively correlated with WOMAC stiffness score (r=0.414, P=0.007). CONCLUSION The external factors of wind-cold dampness have different effects on the clinical symptoms of KOA patients with different TCM constitutions. Compared with other constitutions, the rigid symptoms of patients with asthenic biased constitutions are more susceptible to dampness pathogenic factors.

Rocuronium bromide is an acetylcholine N2 receptor antagonist, which can be used as an auxiliary drug for general anesthesia. It has been reported that rocuronium has two possible metabolic pathways: N-dealkylation and O-deacetylation, which are mainly taken up by liver and excreted by bile in the form of primary drugs. In this paper, the metabolites of rocuronium in human bile were detected by UHPLC-QE-orbitrap-MS, thirteen metabolites were detected, including eleven phase I metabolites and two phase II metabolites, eleven of which had not been previously reported. At the same time, HEK293 cells overexpressing transporter were used to explore the transmembrane transport mechanism of rocuronium, the results showed that rocuronium was the substrate of MATE1, OCT1, OATP1B1 and OATP1B3. The above research results enrich the metabolic pathway of rocuronium in vivo, and put forward the possible transport mechanism of liver uptake and bile excretion, which can better guide the accurate and safe clinical drug application. The collection of human bile samples in this study was approved by the ethics committee of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine (Approval Number: 2019-775-130-01).

OBJECTIVE: To screen the active components from Fuzheng Huayu Recipe (FZHY) and redesign a new recipe composed of the active components, and validate the effect of active components formulation from FZHY against liver fibrosis. METHODS: Thirty-two components from FZHY were evaluated for their activities against liver fibrosis respectively, with 6 kinds of cell models in vitro, including oxidative stressed hepatocyte in L-02, hypoxia injured/proliferative hepatic sinusoidal endothelial cells in SK-HEP-1 and human hepatic sinusoidal endothelial cells (HHSEC), and activated hepatic stellate cell in LX-2. The comprehensive activity of each component against liver fibrosis was scored according to the role of original herbs in FZHY and cell functions in fibrogenesis. Totally 7 active components were selected and combined with equal proportion to form a novel active components formulation (ACF). The efficacy of ACF on liver fibrosis were evaluated on activation of LX-2 and proliferation of HHSEC in vitro and in liver fibrosis model mice induced by dimethylnitrosamine (DMN). Totally 72 mice were divided into 6 groups using a random number table, including normal, high-dose ACF control (20 µ mol/L × 7 components/kg body weight), model, low-, medium-, high-dose ACF groups (5, 10, 20 µ mol/L × 7 components/kg body weight, respectively). Hematoxylin eosin and Sirius red stainings were used to observe inflammation and fibrosis change of liver tissue; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were utilized to observe the effect of ACF on ultrastructure of hepatic sinusoids. RESULTS: Fifteen components from FZHY showed higher scores for their activity on against liver fibrosis. Among them, 7 components including tanshinone II A, salvianolic acid B, cordycepin, amygdalin, quercetin, protopanaxatriol, and schizandrin B were recombined with equal proportions to form ACF. ACF at 1,2, 4 µ mol/L showed strong inhibitory effects on activation of LX-2 and proliferation of HHSEC in vitro (all P<0.01). Compared with the model group, ACF attenuated liver collagen deposition, improved sinusoidal capillarization in a dose-dependent manner (all P<0.05). CONCLUSION ACF exerts a satisfactory effect against experimental liver fibrosis and attenuates sinusoidal capillarization, which warrant a further research and development for herbal components formulation on liver fibrosis.

OBJECTIVE: To investigate the effects of emodin on inflammation and autophagy in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages and reveal its underlying mechanism. METHODS: 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was conducted to find the appropriate dose for emodin. RAW264.7 cells pretreated with different concentrations (0-50 μmol/L) of emodin or vehicle for 2 h prior to exposure to LPS for 16 h. Cell morphology was examined and propidium iodide staining was used to examine cell cycle. Expressions of inflammation-related proteins [nuclear factor-kappaB (NF-κ B) and I-kappaB (I κ B)α] and autophagy-related proteins [light chain (LC)3, P62/sequestosome 1, mammalian target of rapamycin (mTOR), and p-mTOR] were examined using Western blot analysis. Expression of inflammation-related cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 were detected by enzyme-linked immunosorbent assay. Autophagy was examined with LC3B fluorescence intensity and aggregation. The effect of emodin on autophagy was conducted with an autophagy inhibitor, 3-methyladenine (3-MA). RESULTS: The expression of NF-κ B in LPS-induced cells was significantly increased (P<0.01) and simultaneously I κ B α decreased compared with the normal cell (P<0.05). The expressions of TNF-α, IL-β, and IL-6 proteins in the LPS-induced RAW264.7 cells were significantly higher than in the normal cell (P<0.05 or P<0.01). LPS increased the percentage of cells in the G CONCLUSION Emodin could inhibit inflammation of mice RAW264.7 macrophages induced by LPS, possibly through activating autophagy.

BACKGROUND: Knee osteoarthritis (OA) is a major cause of disability among the older adults. Few treatments are safe and effective. Moxibustion is commonly used in treating knee OA in Chinese medicine (CM). CO Laser moxibustion device is a substitute for traditional moxibustion, which mimics the effects of traditional moxibustion. More data are needed to support its application in knee OA. OBJECTIVE: ObjectiveThe trial aims to assess the effect and safety of CO laser moxibustion in patients with knee osteoarthritis compared with a sham control. METHODS: This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial. A total of 392 participants were recruited and assigned to the CO laser moxibustion group and sham laser moxibustion group with a 1:1 ratio at 6 outpatient clinics in Shanghai, China. Participants in both groups received treatment at the affected knee(s) at the acupuncture point Dubi (ST 35) and an Ashi point. There were 3 sessions per week for 4 weeks, and an additional 20-week follow-up. Primary outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores at week 4. Secondary outcomes were WOMAC function score, stiffness score and overall score, VAS pain, Short-Form heath survey (SF-36), and patients' global assessment. The serum levels of cytokines involved in progress of knee OA were explored. Safety was assessed during the whole trial. Masking effectiveness was assessed by both participants and treatment providers.This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial.

DISCUSSION CO laser moxibustion device, designed as a substitute for CM moxibustion, is easy to use and control with no choking smoke and smell, and is a plausible method for double-blind research. This study would provide rigorous evidence for the effect and safety of CO laser moxibustion in treating knee OA (Trial registration No.: ISRCTN15030019).
