The general models for intermediates quality analysis in the production process of Yaobitong capsule were established by near infrared spectroscopy (NIRS) combined with chemometrics, realizing the rapid determination of notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rd and moisture. The spray-dried fine powder and total mixed granule were selected as research objects. The contents of five saponins were determined by high performance liquid chromatography and the moisture content was determined by drying method. The measured contents were used as reference values. Meanwhile, NIR spectra were collected. After removing abnormal samples by Monte Carlo cross validation (MCCV), Monte Carlo uninformative variables elimination (MC-UVE) and competitive adaptive reweighted sampling (CARS) were used to select feature variables respectively. Based on the feature variables, quantitative models were established by partial least squares regression (PLSR), extreme learning machine (ELM) and ant lion optimization least squares support vector machine (ALO-LSSVM). The results showed that CARS-ALO-LSSVM model had the optimum effect. The correlation coefficients of the six index components were greater than 0.93, and the relative standard errors were controlled within 6%. ALO-LSSVM was more suitable for a large number of samples with rich information, and the prediction effect and stability of the model were significantly improved. The general models with good predicting effect can be used for the rapid quality determination of Yaobitong capsule intermediates.

Objective:To analyze the genetic characteristics of coxsackievirus A16 (CVA16) related to hand, foot and mouth disease (HFMD) in Jiaxing from 2021 to 2023, and understand the biological and molecular evolutionary characteristics of CVA16 in this city.Methods:Real-time fluorescent quantitative PCR was used to detect enterovirus and its types in collected HFMD case samples. At the same time, virus isolation and cultivation were performed on positive samples using RD cells. Then high-throughput sequencing of the whole genome was performed on 23 strains of CVA16 identified from the isolated samples. Finally we obtained its whole genome sequence. DNAStar, MEGA 6.0, Simplot 3.5.1 and other bioinformatics software were used to compare and analyze the sequences, construct the phylogenetic tree of VP1 region, and realize the genotype composition. And these software were also used to analyze the homology of the whole genome nucleotide sequence and the encoded amino acids, while know well the amino acid mutation sites and gene recombination in the main regions.Results:The results showed that among the 1 836 HFMD specimens tested from 2021 to 2023, 1 432 (78.00%, 1 432/1 836) were positive for enterovirus general genes, of which 263 were positive for CVA16, accounting for 18.37% (263/1 432) of the confirmed positive cases. Twenty-three CVA16 strains were sequenced and all of them were B1 subtype, of which 6 strains belong to B1b and 17 strains belong to B1a, with B1a being dominant. B1a strains in Jiaxing showed genetic relatedness to strains isolated in Beijing, Yunnan, Guangzhou, Jiangsu and other places in 2018 to 2023, as well as strains from Vietnam, Thailand, and Australia from 2015 to 2017. B1b strains exhibited consistent amino acid mutations of L23M in the VP1 region and V217I in the VP2 region, while B1a strains exhibited amino acid mutations of S14N/D, T164K, and V251I in the VP1 region and R41H in the VP3 region. Compared with the prototype strain, the 23 strains of CVA16 in Jiaxing accumulated the largest number of amino acid mutations in the coding region, with 28 and 50 mutations in the VP1 and 3D regions, respectively. The recombination patterns of B1a and B1b strains were slightly different, with B1a type showing recombination with CVA8 in the 5′-UTR region instead of CVA4, B1a was similar to enterovirus A71 in most of P2 and P3 regions, and recombined with CVA5 in the 3D region of P3.Conclusions:The prevalent strain of CVA16 in Jiaxing may share a common trend of co-circulation and evolution with those in other provinces. The recombination mainly occurs in the 5′-UTR region and non-structural protein coding regions of P2 and P3. Continuous molecular surveillance of CVA16 is in need, and whole-genome sequencing can help understand the genetic variation, evolution, and recombination of strains.This information will provide a more robust basis for the monitoring and early warning, vaccine development, and prevention and control efforts against HFMD.

Objective:To explore the differences in the CVD risk and lipid profiles in psoriatic arthritis (PsA) patients with different disease activity and investigate lipid management status in Chinese patients with PsA.Methods:Patients were enrolled from PKUPsA-PC cohort in Peking University First Hospital from January 2016 to January 2024. Data were collected at their first visit, including disease activity score, lipid profiles and treatment. Two modified CVD risk prediction models (modified China-PAR and modified FRS-CVD) were applied to predict the CVD risk over 10 years. All enrolled patients were subsequently stratified into low, intermediate and high-risk groups. The status of lipid target achievement was assessed based on lipid management recommendations proposed by prediction models. In addition, DAPSA was used to stratify PsA patients into remission, low, moderate and high-disease activity groups, and the differences in CVD risk and lipid profiles among PsA patients with different disease activity status were explored. The t test was used for comparison between 2 groups for measures that conformed to normal distribution; the Mann-Whitney U test was used for comparison between 2 groups for measures that were skewed; and the chi-square test was used for comparison between 2 groups for categorical data.Results:Three hundred and seven PsA patients were included in this study. They were aged 47 (36, 57) years with 121 (39.4%) female, disease duration of skin lesions of 14 (7, 23) years and disease duration of PsA for 3 (1, 8) years. There were 148 (48.2%) patients with dyslipidemia, and 38 (25.7%) of them were receiving lipid lowering drugs. By the modified China-PAR model, there were 174 (56.7%), 76 (24.8%) and 57 (18.5%) in the low-, moderate- and high-risk groups. By the modified FRS-CVD model, there were 173 (56.4%), 58 (18.9%) and 76 (24.7%) patients in the corresponding groups. According to the recommendations for lipid management based on FRS-CVD model, 80 (26.1%) patients did not achieve the target of lipid profile, including 9/174 (5.2%) in the modified model low-risk group, 20/76 (26.3%) in the intermediate-risk group, and 51/57 (89.5%) in the high-risk group, but there were only 12 (15.0%) patients receiving statin therapy. Compared with the remission and low disease activity groups, patients in the moderate-to-high disease activity group were older [50 (37, 60) years vs. 43 (35, 55) years, Z=-2.42, P=0.016]; had a higher proportion of hypertension (30.3% vs. 15.0%, χ2=9.60, P=0.002); and had lower HDL-C levels [1.1 (0.9, 1.3) mmol/L vs. 1.2 (1.0, 1.4) mmol/L, Z=-3.18, P=0.001]. Under the modified China-PAR and modified FRS-CVD risk prediction models, a higher proportion of patients with high disease activity in PsA were stratified at high 10-year CVD risk compared with the remission and low disease activity groups (29.5% vs. 19.6%, χ2=3.81, P=0.005) and (23.5% vs. 12.4%, χ2=6.00, P=0.014). Conclusion:Nearly half of the PsA patients are at medium-high risk to CVD. CVD risk is significantly higher in patients with moderate to high disease activity than in patients with remission and low disease activity. HDL-c levels are lower in patients with high disease activity. Nevertheless a quarter of patients did not achieve the target of lipid profile, and few patients are receiving statin. More attention should be paid to CVD risk evaluation and lipid management as a part of treat-to-target strategy to improve the prognosis.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

This study systematically reviewed the randomized controlled trial(RCT) of traditional Chinese medicine(TCM) treatment of post-stroke depression(PSD) and analyzed the clinical study characteristics and outcome indicators, aiming to optimize the design and establish the core outcome set in the future clinical trials of the TCM treatment of PSD. PubMed, Web of Science, Cochrane Library, EMbase, CNKI, VIP, Wanfang, and SinoMed were searched for the relevant RCT published in recent 3 years. The basic characteristics, intervention measures, and outcome indicators of the included RCT were extracted, and the descriptive analysis was carried out. A total of 76 RCTs were eventually included, with the sample size concentrated in 80-100 cases. The most frequent TCM syndromes were liver depression and Qi stagnation(15 times, 31.91%) and phlegm combined with stasis(5 times, 10.63%). The frequency of intervention methods followed a descending trend of TCM decoction(35 times, 46.05%) and TCM decoction + acupuncture(4 times, 5.26%), Chinese patent medicine(3 times, 3.94%), and the intervention mainly lasted for 1 to 3 months(43 times, 60.56%). The adverse reactions of patients were mainly digestive system reaction(150 patients, 39.37%) and nervous system reaction(112 patients, 29.39%). Most of the included studies had unclear risk of bias, involving 84 outcome indicators, which belonged to 8 indicator domains. The RCTs of TCM treatment of PSD showed a variety of problems, such as non-standard TCM syndrome differentiation, inconsistent names of TCM syndrome scores and measurement tools, low quality, unclear risk of bias, neglect of endpoint indicators, unreasonable selection of substitute indicators, lack of differentiation between primary and secondary outcome indicators, non-standard reporting of safety indicators, insufficient attention to economic indicators, and lack of long-term prognosis evaluation. It is suggested that the future research should improve the quality of methodology and build a standardized core outcome set to promote the development of high-quality clinical research in this field.

This study aims to evaluate the efficacy of Chinese medicine injections in treating transient ischemic attack(TIA) based on network Meta-analysis. Randomized controlled trial(RCT) about Chinese medicine injections in treating TIA were retrieved from PubMed, Web of Science, Cochrane Library, EMbase, CNKI, VIP, Wanfang, and SinoMed with the time interval from inception to March 1, 2024. The methodological quality of the included articles was assessed by ROB 2.0, and the GRADE system was employed to evaluate the quality of evidence. The gemtc package of R 4.1.2 was used to perform the network Meta-analysis. Finally, 63 RCTs with a total sample size of 5 750 cases were included, involving 11 Chinese medicine injections(Shuxuetong Injection, Danhong Injection, Shuxuening Injection, Ginkgo Damo Injection, Shenxiong Glucose Injection, Ligustrazine Injection, Salviae Miltiorrhizae and Ligustrazine Hydrochloride Injection, Salvianolic Acids for Injection, Dengzhan Xixin Injection, Guhong Injection, and Xueshuantong Injection). All patients received conventional western medicine treatment, and the experimental group was additionally treated with Chinese medicine injection. Network Meta-analysis yielded the following results.(1) In terms of improving the clinical total response rate, 11 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Dengzhan Xixin Injection + conventional western medicine had the best effect.(2) In terms of reducing plasma viscosity, 7 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Shenxiong Glucose Injection + conventional western medicine had the best effect.(3) In terms of reducing whole blood high shear viscosity, 6 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Guhong Injection + conventional western medicine had the best effect.(4) In terms of reducing whole blood low shear viscosity, 6 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Shuxuening Injection + conventional western medicine had the best effect.(5) In terms of reducing fibrinogen, 9 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Ginkgo Damo Injection + conventional western medicine had the best effect.(6) In terms of increasing the average blood flow velocity, 3 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Shuxuening Injection + conventional western medicine had the best effect. In summary, compared with conventional western medicine alone, Chinese medicine injections combined with conventional western medicine were effective in improving the clinical total response rate and the average blood flow velocity, as well as reducing plasma viscosity, whole blood high shear viscosity, whole blood low shear viscosity, and fibrinogen. However, due to the limited quality and quantity of the included articles, the above conclusions need to be verified by more high-quality, multi-center, and large-sample RCT.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To develop a rapid assessment scale for healthy aging suitable for the Chinese population.Methods:Based on existing healthy aging assessment scales, national standards, and expert consensus, an initial Healthy Aging Rapid Assessment Scale was drafted through two rounds of expert consultation. A pre-survey was conducted with 3 220 subjects recruited from Guangzhou between July 2023 and July 2024. Items were screened through item analysis and exploratory factor analysis to form the final scale. Reliability and validity of the final scale were validated across five cities: Guangzhou, Dongguan, Shenzhen, Baoding, and Chuxiong.Results:The initial version comprised 36 items, while the finalized scale contained 18 items across three dimensions: metabolic health, mental health, and cognitive health. Test-retest reliability ranged from 0.71 to 0.81 across all study sites. The Spearman-Brown coefficient varied between 0.91-0.96, Cronbach′s α between 0.77-0.83, comparative fit index (CFI) between 0.90-0.98, goodness-of-fit index (GFI) between 0.90-0.99, and root-mean-square error of approximation (RMSEA) between 0.03-0.09. For the three dimensions, reliability and validity metrics demonstrated consistency: Spearman-Brown coefficients 0.87-0.99, Cronbach′s α 0.77-0.83, CFI 0.90-0.98, GFI 0.90-0.99, and RMSEA 0.03-0.09 across four regions.Conclusion:The developed Healthy Aging Rapid Assessment Scale for the Chinese population exhibits robust reliability and validity.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.
