Oxymatrine is an alkaloid from Traditional Chinese Medicine, Sophora flavescens Ait. which has many pharmacological effects. We studied the effects of oxymatrine on the proliferation of human tonsillar cells and mouse splenocytes with or without mitogens. The results show that oxymatrine can augment the proliferation of the human tonsillar cells which show low PHA & tSAC response capacity. On the other hand, oxymatrine can inhibit the proliferation of the human tonsillar cells which show high PHA & SAC responses capacity. The effects of oxymarine on mouse splenocytes are the same with the latter.

Objective　To explore the repair effect of curcumin on injured neurons in Parkinson’s model rats and the related mechanisms.Methods　Forty SD healthy male rats were selected,10 were group,the remaining 30 were established Parkinson’s model,divided into model group,low and high dose groups,and the four groups of rats were intervened separately.The learning and memory abilities of rats in each group were tested.HE staining was performed on brain tissue specimens of rats in each group.The size and number of neurons were counted.The levels of IL-6,IL-1β and TNF-α were detected by enzyme-linked immunosorbent assay.Results　Compared with model group and low dose group,the size and number of neurons in high dose group were higher (P<0.05).Compared with model group and low dose group,rats in high dose group had shorter escape latency and higher number of times crossing the platform at each time point (P<0.05).Compared with model group and low dose group,the levels of IL-6,IL-1β and TNF-α were lower in high dose group (P<0.05).Conclusion　Intervention with curcumin in Parkinson’s model rats can improve the learning and memory ability of rats,increase the size and number of neurons in rat brain tissue,and play a role in neuronal damage repair.Its function may be related to alleviating the inflammatory response in brain tissue,regulating the expression of apoptosis protein.

Objective To investigate the value of peripheral blood soluble interleukin-2 receptor(sIL-2R),CD4+lymphocyte percentage/CD8+lymphocyte percentage ratio(hereinafter referred to as CD4+/CD8+)and tumor necrosis factor-α(TNF-α)in evaluating the efficacy of chemotherapy in elderly patients with newly treated active pulmonary tuberculosis.Methods A total of 102 elderly patients with newly treated active tu-berculosis admitted to the hospital from December 2019 to December 2022 were enrolled in the study as the observation group,and 102 healthy people aged 60 and older who underwent physical examination in the hos-pital during the same period were enrolled as the control group.The levels of sIL-2R,TNF-α and CD4+/CD8+in peripheral blood were compared between the two groups,and the correlations between sIL-2R,TNF-α and CD4+/CD8+were analyzed.The observation group was treated with 2HRZE/4HR anti-tuberculosis treatment regimen.The levels of sIL-2R,TNF-α and CD4+/CD8+in peripheral blood of patients with different efficacy before treatment,1 month and 6 months after treatment in the observation group were compared.The correla-tion between sIL-2R,CD4+/CD8+,TNF-α levels and therapeutic effect was analyzed.The receiver operating characteristic(ROC)curve was used to analyze the efficacy of indicators in evaluating the efficacy of chemo-therapy in elderly patients.Results The levels of sIL-2R and TNF-α in the observation group were higher than those in the control group,while CD4+/CD8+was lower than that in the control group,and the differ-ences were statistically significant(P＜0.05).In the observation group,sIL-2R and TNF-α were negatively correlated with CD4+/CD8+(P＜0.05),sIL-2R was positively correlated with TNF-α(P＜0.05).After 1 month and 6 months of treatment,the levels of sIL-2R and TNF-α in patients with apparent efficacy were low-er than those in patients with efficacy,and the latter were lower than those in patients with no effect,while the CD4+/CD8+in patients with apparent efficacy was higher than that in patients with efficacy,and the latter was higher than that in patients with no efficacy,and the differences were statistically significant(P＜0.05).The levels of sIL-2R and TNF-α were negatively correlated with the efficacy(P＜0.05),and CD4+/CD8+was positively correlated with the efficacy(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of sIL-2R,CD4+/CD8+,and TNF-α used in combination to assess efficacy was significantly greater than the AUCs of the single indicators used in the assessment at each time point of treatment(P＜0.05),and the AUC of the combination of the indicators was greater after 6 months of treatment than after 1 month of treatment(P＜0.05).Conclusion The levels of sIL-2R,CD4+/CD8+and TNF-α are closely related to the ef-ficacy of chemotherapy in elderly patients with newly treated active pulmonary tuberculosis,and the combina-tion of the above indicators has certain reference value in evaluating the efficacy of chemotherapy in patients.
