    Objective:To investigate the anti-tumor effect and mechanism of CⅡ-3 extractive from Periplaneta americana on S180 sarcoma-bearing mice. Methods: S180 sarcoma-bearing mice were randomly divided into model group, positive control (CTX) group, high-dose, medium-dose and low-dose CⅡ-3 groups, and a normal control group, with 10 mice in each group. The pathological changes of tumor tissue in each group were observed after administration, and the tumor inhibition rate was calculated. ELISA kits were used to test the levels of vascular endothelial growth factor(VEGF) and telomerase(TE) in serum. The expression of p53, B-cell lymphoma 2(Bcl-2), cysteinyl asparate specific protease-3(Caspase-3), microvessel density (MVD) and cyclooxygenase-2(COX-2) protein in tumor tissue were detected by immunohistochemistry. Results: The tumor inhibition rates of CTX group, high-dose, medium-dose, and low-dose CⅡ-3 groups were 85.71%, 55.71%, 44.28%, 34.28%, respectively. The necrotic area of tumor tissue was obvious in high-dose and medium-dose CⅡ-3 groups. Compared with the model group, the TE activity was decreased in high-dose CⅡ-3 group(P<0.05), and the expression of p53, Bcl-2, MVD and COX-2 in tumor tissues of high-dose and medium-dose CⅡ-3 groups were significantly decreased(P<0.01), while the Caspase-3 expression was significantly increased(P<0.01). Conclusion: CⅡ-3 can significantly inhibit the growth of S180 sarcoma, and its mechanism may be related to the reduction of TE activity, the decrease of p53, Bcl-2, MVD, COX-2 expression, and the increase of Caspase-3 expression in tumor tissue.

    Objective: To investigate the Th1/Th2 immune imbalance and the involvement of the JAK2-STAT3 signaling pathway in the mechanism of infectious preterm birth. Methods: A total of 60 preterm patients treated at the First Affiliated Hospital of Dali University were selected as the research objects(preterm group). Based on the results of postpartum fetal membrane tissue pathological examination, the preterm group was divided into the infectious preterm birth group and non-infectious preterm birth group. 20 puerperae who had full-term deliveries during the same period were selected as the control group. The expression levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the peripheral blood of the puerperae in the three groups were detected by ELISA kits, and the Th1/Th2 immune regulatory balance index was calculated. The expressions of STAT3 and nuclear factor-κB(NF-κB) proteins in fetal membrane tissue were detected by immunohistochemistry. Results: The expression levels of IFN-γ and TNF-α were significantly elevated in the preterm group(P<0.05), especially in the infectious preterm birth group, indicating that the Th1/Th2 immune balance had a significant shift toward Th1. The expression levels of IL-6, STAT3, and NF-κB proteins were significantly higher in the infectious preterm birth group(P<0.05), while there was no significant difference between the non-infectious preterm birth group and the control group(P>0.05). Conclusion: The Th1/Th2 immune balance may be involved in the occurrence of infectious preterm birth through TNF-α, NF-κB, IL-6 and JAK2-STAT3 signaling pathways.

    Objective: To explore the prognostic value of neutrophil-lymphocyte ratio(NLR) and platelet-lymphocyte ratio (PLR) in patients with maintenance hemodialysis(MHD). Methods: Medical records of 119 patients who underwent MHD treatment at Baoshan People's Hospital from January 2017 to October 2020 were collected, and the patients were grouped according to the median PLR and NLR, and the clinical data of each group were evaluated. Kaplan-Meier survival curve was used to analyze all-cause mortality rates in the NLR and PLR groups. COX regression models were used to analyze the risk factors for all-cause mortality in the patients. The predictive value of NLR for all-cause mortality in MHD patients was evaluated using receiver operator characteristic(ROC) curve. Results: In the PLR group, there were no significant differences in laboratory parameters and all-cause mortality rates between the two groups(P>0.05). In the NLR group,  there were significant differences in albumin, hypersensitive C-reactive protein (hsCRP), single-pool urea clearance rate, and all-cause mortality rates between the two groups (P<0.05). The adjusted COX regression model showed that the increasing age, elevated NLR, hsCRP and decreased single-pool urea clearance rate were independent predictors of all-cause mortality rate. The ROC curve analysis showed that the area under the curve for NLR in predicting all-cause mortality in MHD patients was 0.716(95%CI: 0.598-0.833), with a sensitivity of 78.30% and specificity of 64.60%. Conclusion: NLR can independently predict the prognosis of MHD patients.

    Objective: To analyze the predictive value of stone CT value for the efficiency of flexible ureteroscopic lithotomy. Methods: A retrospective analysis was conducted on the medical records of 135 patients who underwent flexible ureteroscopic lithotomy at Changshou District People's Hospital in Chongqing. The patients' general preoperative information and stone data(number, volume, and CT value) were recorded. After 3 months of postoperative follow-up, the patients were divided into stone clearance group and stone residue group based on the stone clearance status. Univariate analysis, multivariate Logistic regression analysis, and receiver operator characteristic(ROC) curve analysis were performed. Results: The univariate analysis showed that there were statistically significant differences in stone number, stone volume, and stone CT value between the two groups(P<0.05). The results of multivariate Logistic regression analysis showed that the stone number ≥2 and elevated stone CT value were risk factors for residual stones after flexible ureteroscopic lithotomy(P<0.05). The ROC curve analysis results showed that the predicted cut-off value of stone CT for residual stones after flexible ureteroscopic lithotomy was 1 092.75 HU, with an area under the curve of 0.725(95%CI: 0.632-0.791), sensitivity of 51.91%, and specificity of 84.72%. Conclusion: The residual stones after flexible ureteroscopic lithotripsy are mainly influenced by stone number and stone CT value. Stone CT value has a high diagnostic efficacy in predicting residual stones after flexible ureteroscopic lithotripsy.

    Objective: To explore the correlation between hyperthyroidism and bone mineral density(BMD) in postmenopausal women. Methods: A total of 220 postmenopausal women who visited the First People's Hospital of Yunnan Province from October 2021 to April 2022 were selected as the study subjects. BMD and thyroid function indicators were compared among all participants. The patients with hyperthyroidism were divided into different subgroups according to the duration of the disease, and BMD measurements were compared among the subgroups. Results: The BMD values of lumbar vertebra, neck of femur, Wards triangle, greater trochanter and the whole body in patients with hyperthyroidism were significantly lower than in those without hyperthyroidism. Among patients with hyperthyroidism, those with a disease duration of ≥1 year had significantly lower BMD values in the lumbar spine compared to those with a disease duration of <1 year(P<0.05). The levels of free triiodothyronine(FT3) were negatively correlated with BMD values in the neck of femur, Wards triangle, and the whole body, while the levels of free thyroxine(FT4) were negatively correlated with BMD values in Wards triangle. Conclusion: The BMD values of postmenopausal women with hyperthy-roidism are significantly lower than those without hyperthyroidism. Prolonged disease duration is more likely to lead to a decrease in lumbar spine BMD. FT3 and FT4 levels are negatively correlated with BMD values.
