Juvenile idiopathic arthritis (JIA) is the most common condition of chronic rheumatic disease in children. JIA is an autoimmune or autoinflammatory disease, with unclear mechanism and limited treatment efficacy. Recent studies have found a number of alterations in gut microbiota and its metabolites in children with JIA, which are related to the development and progression of JIA. This review focuses on the influence of the gut microbiota and its metabolites on immune function and the intestinal mucosal barrier and discuss the key role of the gut-joint axis in the pathogenesis of JIA and emerging treatment methods based on gut microbiota and its metabolites. This review could help elucidate the pathogenesis of JIA and identify the potential therapeutic targets for the prevention and treatment of JIA.

To facilitate the early intelligent screening of pediatric genu valgum, this study develops a deep learning-based gait recognition model tailored for clinical application. The model is constructed upon a three-dimensional residual network architecture and incorporates a triplet attention module alongside a spatial hierarchical pooling module, jointly enhancing feature interaction across temporal, spatial, and channel dimensions. This design ensures an optimal balance between representational capacity and computational efficiency. Evaluated on a self-constructed dataset, the model achieves precision of 98.0%, 97.1%, and 96.5%, recall rates of 97.5%, 97.0%, and 95.0%, and F 1-scores of 0.98, 0.97, and 0.96 on the training, validation, and test sets, respectively, demonstrating excellent recognition performance and strong generalization ability. Ablation experiments confirm the importance of the proposed model's core components in improving performance, and comparative experiments further highlight its significant advantages in recognition accuracy and robustness. Visualization experiments reveal that the model effectively focuses on key regions of gait images, with attention regions aligning closely with clinical anatomical landmarks, thereby enhancing the interpretability of the model's decision-making in clinical applications. In summary, the proposed model not only offers an efficient and reliable technical solution for early intelligent screening of genu valgum in children, but also provides a practical pathway for applying gait recognition technology in medical diagnosis.

OBJECTIVE:
To assess the cardioprotective effect and impact of Qishen Granules (QSG) on different ischemic areas of the myocardium in heart failure (HF) rats by evaluating its metabolic pattern, substrate utilization, and mechanistic modulation.
METHODS:
In vivo, echocardiography and histology were used to assess rat cardiac function; positron emission tomography was performed to assess the abundance of glucose metabolism in the ischemic border and remote areas of the heart; fatty acid metabolism and ATP production levels were assessed by hematologic and biochemical analyses. The above experiments evaluated the cardioprotective effect of QSG on left anterior descending ligation-induced HF in rats and the mode of energy metabolism modulation. In vitro, a hypoxia-induced H9C2 model was established, mitochondrial damage was evaluated by flow cytometry, and nuclear translocation of hypoxia-inducible factor-1 α (HIF-1 α) was observed by immunofluorescence to assess the mechanism of energy metabolism regulation by QSG in hypoxic and normoxia conditions.
RESULTS:
QSG regulated the pattern of glucose and fatty acid metabolism in the border and remote areas of the heart via the HIF-1 α pathway, and improved cardiac function in HF rats. Specifically, QSG promoted HIF-1 α expression and entry into the nucleus at high levels of hypoxia (P<0.05), thereby promoting increased compensatory glucose metabolism; while reducing nuclear accumulation of HIF-1 α at relatively low levels of hypoxia (P<0.05), promoting the increased lipid metabolism.
CONCLUSIONS
QSG regulates the protein stability of HIF-1 α, thereby coordinating energy supply balance between the ischemic border and remote areas of the myocardium. This alleviates the energy metabolism disorder caused by ischemic injury.

ObjectiveTo objectively analyze the effects of traditional Chinese Medicine (TCM) multi-channel intervention on the ovarian function,TCM syndromes and natural conception of poor ovarian responders(kidney-Yin deficiency,liver depression and blood stasis pattern) who planned to receive another in vitro fertilization embryo transfer(IVF-ET)antagonist regimen. MethodThe 128 low-prognosis patients (kidney Yin deficiency,liver depression and blood stasis pattern) who attended the West China Second University Hospital, Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected,and then divided into the treatment group and the control group according to the random number table,with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone(DHEA),while the treatment group was treated with multi-channel TCM(oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema). After 3 menstrual cycles,the relevant indicators for ovarian function evaluation,TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment,the basal follicle stimulating hormone(bFSH),bFSH/basal luteinizing hormone(bLH),basal estradiol(bE2),antral follicle count(AFC),the number of oocytes obtained,the number of normal fertilization,the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment(P<0.05,P<0.01). For the control group, the bFSH/bLH and TCM syndrome scores were increased after treatment(P<0.05), while the bFSH,bFSH/bLH,bE2,AFC,the number of oocytes obtained,the number of normal fertilization,and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment,bFSH,bFSH/bLH,bE2,AFC,the number of normal fertilization,the number of superior embryos and TCM syndrome scores in the treatment group were better (P<0.05,P<0.01),while there was no significant difference in the number of oocytes obtained. After treatment,there were 3 cases of natural conception in the treatment group,while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency,liver depression and blood stasis pattern,multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH,bFSH/bLH values,improve the levels of bE2,increase AFC,the number of oocytes obtained,the number of normal fertilization and the number of superior embryos,improve ovarian function,menstruation and TCM syndromes,improve their quality of life,and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.

Journal of Public Health and Preventive Medicine 2024;35(2):144-147
Objective To investigate the serum levels of thyroid function and hs-CRP expression in patients with syphilis and their relationship with coagulation function. Methods A total of 80 syphilis patients admitted to Bazhong Central Hospital from January 2020 to January 2022 were selected as the study subjects and set as the observation group. In addition, 80 healthy individuals were selected as the control group, and 80 psoriasis patients were selected as the disease control group. Thyroid function, hs-CRP and coagulation function among different groups were compared. The correlation between thyroid function, hs-CRP, and coagulation function in patients with syphilis was analyzed, and the effectiveness of these parameters in predicting syphilis was analyzed. Results The values of FT3, FT4, TSH and hs-CRP in the observation group were higher than those in the control group and the disease control group (P<0.05). The abnormal rates of thyroid function and hs-CRP level in the observation group were higher than those in the control group and the disease control group (P<0.05). PT, APTT, and TT of the observation group were higher than those of the control group and the disease control group (P<0.05). The abnormal rate of coagulation function in the observation group was higher than that in the control group and the disease control group (P<0.05). The levels of FT3, FT4, TSH, hs-CRP, PT, APTT, and TT in the first stage were lower than those in the second and third stages, while these parameters in the secondary stage were lower than those in the third stage (P<0.05). The severity of syphilis was positively correlated with FT3, FT4, hs-CRP, APTT, and TT (P<0.05). Among these indicators, TT was more effective in the diagnosis of syphilis. Conclusion Syphilis patients have hyperthyroidism, accompanied by coagulation dysfunction and abnormal increase in hs-CRP, which are all related to the condition of syphilis patients. The combined prediction of syphilis patients has high effectiveness.

ObjectiveTo objectively evaluate the clinical efficacy of multiple therapies of traditional Chinese medicine (TCM) in low-prognosis patients who received antagonist protocol for in vitro fertilization and embryo transfer (IVF-ET) again. MethodA total of 128 patients with kidney Yin deficiency, liver depression, and blood stasis who planned to receive antagonist protocol for IVF-ET in the West China Second Hospital of Sichuan University were enrolled and assigned into two groups by random number table method. The observation group (64 casces) was treated by oral administration of Chinese medicine decoction + enema of kidney-tonifying and blood-activating method + auricular point sticking + oral administration of dehydroepiandrosterone (DHEA), while the control group (64 casces) was treated by only oral administration of DHEA. After treatment for three menstrual cycles, both groups received the antagonist protocol for IVF-ET. The TCM syndrome scores, basic sex hormone levels, antral follicle count (AFC), the usage of gonadotropin (Gn), endometrial receptivity indicators, embryo quality indicators, and pregnancy outcomes were compared between the two groups. ResultAfter treatment, the observation group showed decreased follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratio, lowered level of estradiol (E2), increased AFC, decreased amount and days of Gn usage, improved endometrial receptivity indicators (endometrial thickness on trigger and ET days, proportion of endometrial type A in endometrial types and the level of E2 on trigger day) and embryo quality indicators (the rates of mature follicles, fertilization, normal fertilization, and premium embryos), and decreased TCM syndrome scores (P<0.05, P<0.01). Moreover, the observation group had lower FSH/LH ratio, E2 level, and amount of Gn usage, higher AFC, poorer endometrial receptivity and embryo quality indicators, and lower TCM syndrome scores than the control group after treatment (P<0.05, P<0.01). In addition, except for 3 cases of natural pregnancy, the observation group outperformed the control group in terms of improving the clinical pregnancy rates during initiation cycle and transplantation cycle and clinical pregnancy rate and decreasing biochemical pregnancy rate and early abortion rate (P<0.05). ConclusionCombined therapies of TCM can alleviate the clinical symptoms, reduce TCM syndrome scores, reduce the Gn usage amount, improve the number and quality of embryos and endometrial receptivity, and coordinate the synchronous development of endometrium and embryo. In this way, they can increase the clinical pregnancy rate and reduce biochemical pregnancy rate and early abortion rate in the low prognosis patients with kidney yin deficiency, liver depression, and blood stasis who are undergoing IVF-ET again.
