This paper interprets the disease name related to bi （痹） disease in traditional Chinese medicine （TCM） from the perspective of micropathological phenotypes in knee osteoarthritis （KOA）. By systematically reviewing classical TCM literature on the pathogenesis and clinical features of different subtypes such as damp-retention bi， bone bi， and tendon bi， and integrating these with current research on pathological subtypes of KOA including the synovitis type， cartilage-meniscus type， and subchondral bone type， the study explores the correlation between traditional disease terms and modern micropathological phenotypes. The author proposes subtype classifications of damp-retention bi corresponding to synovial inflammation， bone bi related to abnormal subchondral bone remodeling， and tendon bi representing cartilage and meniscus degeneration. This approach provides a microscopic biological explanation for TCM syndrome differentiation and offers new perspectives for advancing integrative diagnostic and therapeutic strategies in both Chinese and western medicine.

Thymocyte selection-associated high mobility group box (TOX), a member of the high mobility group protein super-family, plays an important role in T cell development, functional maintenance, and exhaustion. It has been recently found that TOX exerts critical immunoregulatory functions during pathogen infections, and TOX expression is strongly associated with the intensity and tolerance of host immune responses. This review systematically summarizes the structural and functional features of TOX and focuses on its expression dynamics, mechanisms of action, and immunomodulatory effects during viral, bacterial, and parasitic infections, which provides a theoretical support to better understanding of the role of TOX in infectious diseases and provides new insights into development of potential immunotherapeutic strategies targeting TOX.

Objective This study aimed to assess the clinical efficacy of Shenling Baizhu Granules in treating low anterior resection syndrome(LARS)in rectal cancer.Methods The study employed a randomized,double-blind,placebo-parallel controlled,single-center,validity-tested clinical trial design.December 2019 to June 2022,the Department of Gastrointestinal Surgery and Integrated Traditional Chinese and Western Medicine of Peking University First Hospital recruited 110 patients who had undergone low anterior resection(LAR)for rectal cancer and subsequently developed LARS.These patients,meeting the enrollment criteria,were randomly assigned into the treatment group(55)and the control group(55)using the double-blind method principle.The randomization table was generated by SAS 9.2 software employing the double-blind method.The treatment group received oral Shenling Baizhu Granules,while the control group received oral placebo granules.Both groups commenced treatment on the 10th day after-surgery for 30 consecutive days.Patients were evaluated using LARS score,traditional Chinese medicine(TCM)symptom grading,and XU Zhongfa score before treatment,on the 15th day of treatment,and on the 1st day after treatment cessation.Results Out of 110 patients,107 were included in the full analysis set for efficacy analysis:55 patients in the treatment group and 55 patients in the control group.One case in the treatment group was excluded(against protocol),and two cases in the control group were excluded(one lost to follow-up,one against protocol).Baseline data between the two groups were consistent,with no statistically significant difference.Before treatment,LARS scores for the treatment and control groups were 33.0(31.0,36.0)and 34.0(32.0,37.0)respectively.Patients with TCM symptom scores of grades 2 to 3 accounted for 92.73％and 90.57％in the treatment and control groups,respectively,with no statistically significant difference.After 30 days of treatment,LARS scores for the treatment and control groups were 21.0(19.8,23.0)and 26.0(22.0,28.0)respectively.The percentage of patients with TCM symptom scores of grades 2 to 3 decreased to 33.33％in the treatment group and 66.04％in the control group,with a statistically significant difference.Shenling Baizhu Granules showed rapid improvement in watery or loose stools in post-operative rectal cancer patients.After 30 days of treatment,Shenling Baizhu Granules significantly improved appetite,stool consistency,abdominal distension,abdominal pain,and eructation symptoms in postoperative rectal cancer patients.Before treatment,the XU Zhongfa scores for the treatment and control groups were 3.0(2.0,4.3)and 4.0(2.0,4.0)respectively,with no statistically significant difference.After 30 days of treatment,the XU Zhongfa scores for the treatment and control groups were 7.0(6.0,8.0)and 6.0(5.0,7.0)respectively,with the treatment group significantly higher than the control group(P＜0.01).Conclusion Shenling Baizhu Granules can effectively improve LARS symptoms in patients following LAR of rectal cancer within a short period of time.

Objective To analyze the characteristics of platelet changes and their influencing factors during postoperative hospitalization in patients who underwent transcatheter aortic valve implantation (TAVI). Methods The patients who underwent TAVI at Beijing Anzhen Hospital Valve Surgery Center between March 2017 and October 2021 were retrospectively selected. The patients were divided into a self-limiting group and a non-self-limiting group according to the characteristics of postoperative platelet decline. In addition, the general preoperative data, preoperative and postoperative ultrasound data, intraoperative data, and the use of anticoagulant drugs during the postoperative stay in the hospital were compared between the two groups. Results A total of 249 patients were enrolled in this study. There were 175 (70.3%) patients in the self-limiting group, including 100 males and 75 females, and there were 74 (29.7%) patients in the non-self-limiting group, including 43 males and 31 females, with no statistical difference between the two groups (P=0.863). The mean age of patients was 73.11±8.88 years in the self-limiting group and 71.54±10.39 years in the non-self-limiting group (P=0.231). The decline of platelets in the self-limiting group generally occurred on the postoperative day 2 and reached the lowest count on the postoperative day 4, and returned to the baseline level on the postoperative day 5-7, while the platelets in the non-self-limiting group changed by simple rise, fall or irregular fluctuation. Patients in the self-limiting group had severer preoperative aortic stenosis (P<0.001) and used more extracorporeal circulation assistance during surgery (P<0.001). Postoperatively, patients in the self-limiting group were more likely to have periaortic valve leakage than those in the non-self-limiting group (P=0.013). Conclusion Platelet changes in most patients after TAVI show a self-limiting decline, which may be related to the severity of patients’ preoperative aortic stenosis, intraoperative extracorporeal circulation device use, and postoperative perivalvular leakage.

ObjectiveTo evaluate the effect and safety of Jiuxin Pill （救心丸） on exercise tolerance and quality of life in patients with stable angina pectoris （SAP）. MethodsA randomised， double-blind， placebo-controlled， multicentre study design was used to enroll 170 patients of SAP from nine centres， which were divided into 85 patients each in the trial group and control group with 1∶1 ratio. Both groups maintained the original western medicine treatment plan， and added Jiuxin Pill or placebo respectively， 2 pills （0.05 g） each time twicely for 28 days. The main outcomes were total exercise time （TED） in the exercise treadmill test and Seattle Angina Questionnaire （SAQ） scores including physical limitation （PL）， angina stability （AS）， angina frequency （AF）， treatment satisfaction （TS）， and disease perception （DP）. The secondary outcomes were exercise treadmill test indicators including heart rate recovery in 1 min （HRR1）， metabolic equivalents （METs）， maximum magnitude of ST-segment depression， and the Borg rating of perceived exertion scale， the average number of angina attacks per week， withdrawal and reduction rate of nitroglycerin， traditional Chinese medicine syndrome scores， incidence of major adverse cardiovascular events. Safety indicators were evaluated and the occurrence of adverse events during the trial was recorded. Data was collected before treatment， day 28±2 in treatment period， and follow-up at day 56 which is 28±2 days after treatment period finished. ResultsEighty-four and eighty-five patients respectively from trial group and control group were included to the full analysis set （FAS） and safety analysis set （SS）. Compared with the group before treatment and with the control group after treatment， the trial group had higher TED， HRR1， and METs， and lower maximum magnitude of ST-segment depression and Borg rating of perceived exertion scores after treatment （P＜0.01）. Compared with the group before treatment and with the control group after treatment and at follow-up， the total SAQ score and scores of AS， AF， TS and DP of the trial group after treatment and at follow-up elevated， while the average number of angina attacks per week and traditional Chinese medicine syndrome scores reduced （P＜0.01）. There was no statistically significant difference in the withdrawal and reduction rate of nitroglycerin between groups （P＞0.05）. Major adverse cardiovascular events occurred in 1 case （1/84， 1.19%） in the trial group and 1 case （1/85， 1.18%） in the control group， and the difference between groups was not statistically significant （P＞0.05）. A total of 3 cases of adverse events occurred in the trial group （3/84， 3.57%）， and a total of 6 cases of adverse events occurred in the control group （6/85， 7.06%）， and there was no statistically significant difference in the incidence of adverse events between groups （P＞0.05）. ConclusionIn the treatment of SAP， Jiuxin Pill combined with conventional western medicine can further enhance exercise tolerance， improve quality of life， and demonstrate great safety.

Objective To investigate the feasibility of constructing the risk index of Echinococcus infection based on the classification of echinococcosis lesions, so as to provide insights into the management of echinococcosis. Methods The imaging data of echinococcosis cases were collected from epidemiological surveys of echinococcosis in China from 2012 to 2016, and the detection of incident echinococcosis cases was captured from the annual echinococcosis prevention and control reports across provinces (autonomous regions) and Xinjiang Production and Construction Corps in China from 2017 to 2022. After echinococcosis lesions were classified, a risk index of Echinococcus infection was constructed based on the principle of discrete distribution marginal probability and multi-group classification data tests. The correlation between the risk index of Echinococcus infection and the detection of incident echinococcosis cases was evaluated in the provinces (autonomous regions and corps) from 2017 to 2022, and the correlations between the short and medium-term risk indices and between the medium and long-term risk indices of Echinococcus infection were examined using a univariate linear regression model. Results A total of 4 014 echinococcosis cases in China from 2012 to 2016 were included in this study. The short-, medium- and long-term risk indices of E. granulosus infection varied in echinococcosis-endemic provinces (autonomous regions and corps) of China (χ² = 4.12 to 708.65, all P values < 0.05), with high short- (0.058), medium- (0.137) and long-term risk indices (0.104) in Tibet Autonomous Region, and the short-, medium- and long-term risk indices of E. multilocularis infection varied in echinococcosis-endemic provinces (autonomous regions and corps) of China (χ² = 6.74 to 122.60, all P values < 0.05), with a high short-term risk index in Sichuan Province (0.016) and high medium- (0.009) and long-term risk indices in Qinghai Province (0.018). There were no significant correlations between the risk index of E. granulosus infection and the detection of incident cystic echinococcosis cases during the study period (t = −0.518 to 2.265, all P values > 0.05), and strong correlations were found between the risk indices of E. multilocularis infection and the detection of incident alveolar echinococcosis cases (including mixed type) in 2018, 2020, 2021, 2022, during the period from 2017 through 2020, from 2017 through 2021, from 2017 through 2022 (all r values > 0.7, t = 2.521 to 3.692, all P values < 0.05). Linear regression models were established between the risk index of E. multilocular infection and the detection of alveolar echinococcosis cases (including mixed type), and the models were all statistically significant (b = 0.214 to 2.168, t = 2.458 to 3.692, F = 6.044 to 13.629, all P values < 0.05). The regression coefficients for the correlations between the medium- and short-term, and between the long- and medium-term risk indices of E. granulosus infection were 2.339 and 0.765, and the regression coefficients for the correlations between the medium- and short-term, and between the long- and medium-term risk indices of E. multilocular infection were 0.280 and 1.842, with statistical significance seen in both the regression coefficients and regression models (t = 16.479 to 197.304, F = 271.570 to 38 928.860, all P values < 0.05). Conclusions The risk index of Echinococcus infection has been successfully established based on the classification of echinococcosis lesions, which may provide insights into the prevention and control, prediction, diagnosis and treatment, and classified management of echinococcosis.

ObjectiveTo investigate the genetic polymorphism and structure of 47 autosomal microhaplotypes in the Han population in Changshu City, Jiangsu Province, and to evaluate the forensic efficiencies and forensic parameters. MethodsThe DNA library of unrelated individual samples was prepared according to MHSeqTyper47 kit manual and sequenced on the MiSeq FGx platform. Microhaplotype genotyping and sequencing depth statistics were processed using MHTyper. The genetic information of samples was then evaluated. The fixation index and genetic distance between the Jiangsu Changshu population and the reference populations in the 1000 Genomes Project phase 3 (1KG) were calculated, and forensic parameters were evaluated. ResultsThe fixation index and genetic distance between the Han population in Changshu, Jiangsu, and the CHB (Han Chinese in Beijing, China) reference population in 1KG were the lowest. The effective allele number (A_e) of each locus is also the closest between the two populations. The combined matching probability (CMP) of the Changshu Han population is close to the 5 populations of the East Asian reference super-population in 1KG, which is 1.25×10^-36, and the combined probability of exclusion reached 0.999 999 999 964 1. ConclusionThis study reported the genetic polymorphism and allele frequency of 47 microhaplotypes in a Han population in Changshu City, Jiangsu Province. This information provides a data basis for 47 microhaplotypes in forensic applications. In addition, the polymorphism differences between the 1KG reference population and the Han population in Changshu, Jiangsu were compared, and the genetic structure of 47 microhaplotypes in the Han population in Changshu, Jiangsu was revealed. In general, the reference data of the East Asian super-population in 1KG is more in line with the genetic characteristics of Han population in Changshu, Jiangsu.

Osteoporosis and knee osteoarthritis often co-occur and are closely related in terms of epidemiology， clinical symptoms， pathogenesis and other aspects. Therefore， it is necessary to manage the co-morbidity and treat the two as a whole. Based on the overall relationship between wei （痿） and bi （痹） in TCM， it is believed that osteoporosis and knee osteoarthritis have marrow loss and bone atrophy as the core pathogenesis of co-morbidity， and microfractures as the central pathological link. The overall treatment is rooted in boosting kidney， supplementing marrow and strengthening the bones. According to the pathological manifestations of microfractures in the process of co-morbidity， and the different deficiency and excess characteristics of wei and bi， it can be divided into three types， "wei emerging with mild bi"， "wei and bi progressing simultaneously"， and "emphasis on both wei and bi"， for treatment. In terms of "wei emerging with mild bi"， that is the early stage of osteoporosis， the traditional Daoyin （导引） is the main therapy. For "wei and bi progressing simultaneously"， it can be divided into three stages further， including the onset stage， remission stage， and recovery stage of knee pain， treated with Taohong Siwu Decoction （桃红四物汤）， Bushen Huoxue Formula （补肾活血方） and self-made Bushen Qianggu Formula （补肾强骨方） as the main formula respectively. For "emphasis on both wei and bi"， the proven formula， Qianggu Zhitong Formula （强骨止痛方）， is taken as the main prescription.
