ObjectiveTo construct a risk prediction model for frequent acute exacerbations of chronic obstructive pulmonary disease (COPD) under disease-syndrome combination, thus providing decision support for precise clinical intervention. MethodsA total of 2 029 patients with acute exacerbations of COPD admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from January 2020 to August 2024 were retrospectively included. These patients were classified into groups of frequent acute exacerbations (≥2 times/year) and infrequent acute exacerbations (<2 times/year) according to the hospitalization times per year. Risk factors were screened by LASSO regression combined with logistic regression, and a nomogram model was constructed. The model performance was assessed based on the area under the curve (AUC), calibration curves, and decision curve analysis (DCA). ResultsThe differences in baseline characteristics between the frequent acute exacerbations group (1 196 cases) and infrequent acute exacerbations group (833 cases) were not statistically significant. LASSO regression combined with multivariate logistic regression screened the following independent risk factors: body mass index (BMI), hospitalization days, number of smoking years, place of residence, use of noninvasive ventilators, oxygen-demanding therapy, liver cirrhosis, use of systemic glucocorticosteroids, and traditional Chinese medicine syndrome (phlegm and stasis obstructing the lung). The nomogram model showed good discrimination and calibration in both the training set (AUC=0.748) and validation set (AUC=0.774). ConclusionThe risk prediction model for frequent acute exacerbations of COPD, integrating traditional Chinese medicine syndrome, constructed in this study has high accuracy. It can provide a scientific basis for early clinical identification of high-risk patients and individualized intervention.

ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine (TCM) surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted, collecting clinical data from 17,831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group (11,646 cases), and those receiving TCM surgical operations were categorized into the TCM surgery group (6185 cases). Propensity score matching (1∶1 matching) was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate, and secondary outcomes included the main symptoms (rectal bleeding, degree of prolapse) and secondary symptoms (anal distension, anal edema, wound secretion and exudation, anal stenosis, residual skin tags, perianal itching, and anal pain) measured on days 7, 28, and 60 after discharge. ResultsAfter matching, 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge, the TCM surgical group had superior improvement in rectal bleeding [OR=5.786, 95%CI (3.092,10.827)], degree of prolapse [OR=4.510, 95%CI (1.649,12.333)], and anal edema [OR=3.188, 95%CI (1.295,7.845)] compared to the western surgical group. At 60 days post-discharge, the TCM group still showed advantages in improving rectal bleeding [OR=5.237, 95%CI (1.077,25.464)] and anal pain [OR=11.697, 95%CI (1.186,115.336)] (P<0.05). Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% (8/726), while that in the western surgery group was 2.3% (10/444), with no statistically significant difference between the two groups (P>0.05). ConclusionBased on real-world data, TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement, particularly in terms of hemostasis, reducing swelling, and alleviating prolapse of anal masses.

Triatoma rubrofasciata is currently the most widely distributed species of Triatoma worldwide, and it is also widespread in southern China. T. rubrofasciata has been proven to transmit Trypanosoma cruzi, and is one of vectors transmitting Chagas disease, which poses a potential risk for transmission of imported Chagas disease in China. Findings from latest studies have shown that T. rubrofasciata naturally infects T. lewisi, T. conorhini, and T. rangeli, which undoubtedly increases significant risks of and challenges to trypanosomiasis control in China. This article briefly describes the species of T. rubrofasciata-transmitted trypanosomes, and summarizes the epidemiological characteristics of trypanosomiasis, so as to provide insights into T. rubrofasciata-transmitted trypanosomiasis surveillance and control, and prevention of trypanosomiasis development and transmission in China.

Objective To determine the effect of knee extension constraint training on bilateral knee biomechanics and bilateral symmetry in running after anterior cruciate ligament reconstruction(ACLR).Methods A total of 33 male patients with unilateral ACL injuries were randomly assigned to a BRACE group of 14 wearing a brace with limitation of knee extension,a PLACEBO group of 10 wear-ing a brace without limitation of knee extension,and a CONTROL group of 9,wearing no brace.All groups underwent unilateral hamstring-auto graft ACLR surgery,immediately followed by 12-week rou-tine rehabilitation.Between week 13 and 48,both the BRACE and PLACEBO groups wore braces for one hour on Mondays.Then,running biomechanical tests were performed at the ends of Week 12 and Week 48,and the bilateral knee extension/flexion angle,moment and inter-leg difference(ILD)were calculated.One-dimensional statistical parametric mapping(SPM1d)two-way ANOVA with repeated measures on one factor was used to identify differences in bilateral knee biomechanics and ILD among the three groups before and after the intervention.Results There was no significant interaction effect of group and time on bilateral knee flexion angle,knee extension moment,and ILD in running(P>0.05).Moreover,no significant effect of group was found on the bilateral knee biomechanics and ILD in running(P>0.05).Additionally,significant effects of time were observed on bilateral knee flexion angle and extension moment in running.However,bilateral knee flexion angle decreased during termi-nal stance(ACLR leg:89%~100%,P=0.036;non-ACLR leg:94%~100%,P=0.046),while the bi-lateral knee extension moment increased during mid-stance(ACLR leg:17%~59%,P<0.001;non-ACLR leg:38%~61%,P<0.001)between week 12 and 48.Conclusion In this study,no improvement was found in the abnormal knee biomechanics and symmetry during running in male patients after uni-lateral ACL reconstruction through long-term knee extension constraint training.Moreover,within one year after ACL reconstruction,the knee extension moment of the surgical limb increased gradually over time,with no changes in the knee flexion angle of the surgical limb and bilateral knee symme-try,suggesting that abnormal knee biomechanics and bilateral symmetry should be paid attention to in the post-surgery rehabilitation.

Objective:To investigate the effect of Gexia Zhuyu decoction on Toll-like receptor 4 (TLR4)/Nuclear factor-kappaB (NF-κB) signaling pathway on ulcerative colitis and intestinal mucosal barrier.Methods:A total of 86 cases of ulcerative colitis admitted to Xi′an Traditional Chinese Medicine (TCM) Hospital from March 2019 to July 2023 were prospectively included and divided into observation group and control group according to random number table method, with 43 cases in each group. The control group was treated with mesalazine enteric-coated tablets; The observation group was treated with mesalazine enteric-coated tablets combined with Gexia Zhuyu decoction for removing stasis. The clinical efficacy of the two groups was compared in terms of TCM syndrome score, intestinal mucosal barrier function index [diamine oxidase (DAO), D-lactic acid (D-LA)], TLR4/NF-κB signaling pathway expression and inflammatory factor index [interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α)] before and after treatment. The occurrence of adverse reactions was also compared.Results:The total effective rate of observation group was higher than that of control group (χ 2=4.074, P=0.044). Before treatment, there was no significant difference in TCM syndrome scores between the two groups (all P>0.05). After treatment, the TCM syndrome scores of both groups were lower than those before treatment (all P<0.05), and the TCM syndrome scores of the observation group were lower than those of the control group (all P<0.05). Before treatment, there were no significant differences in D-LA and DAO levels between the two groups (all P>0.05). After treatment, the levels of D-LA and DAO in both groups were lower than before treatment (all P<0.05), and the levels of D-LA and DAO in the observation group were lower than those in the control group (all P<0.05). After treatment, the mRNA expressions of TLR4 and NF-κB in both groups were decreased compared with those before treatment, and the mRNA expressions of TLR4 and NF-κB in the observation group were lower than those in the control group (all P<0.05). After treatment, the levels of IL-6, IL-8 and TNF-α in both groups were decreased compared with those before treatment (all P<0.05), and the levels of IL-6, IL-8 and TNF-α in the observation group were lower than those in the control group (all P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (χ 2=2.346, P=0.126). Conclusions:The application of Gexia Zhuyu decoction in the treatment of ulcerative colitis can not only effectively improve the clinical symptoms, signs and intestinal mucosal barrier function, but also improve the inflammatory response by mediating TLR4/NF-κB signaling pathway.
