OBJECTIVEThe progression of prostate cancer (PCa) after endocrine therapy varies widely in different PCa patients. This study aims to analyze the factors that influence the progression-free survival time of PCa patients after endocrine therapy in an attempt to improve the prognosis of the disease.

METHODSWe reviewed the clinicopathological data of 116 cases of prostate cancer treated by endocrine therapy, analyzed the clinicopathological factors that influence the progression-free survival time of PCa patients using univariate (log-rank test) and multivariate Cox proportional hazard models, and investigated the correlation among these factors by Spearman rank correlation analysis.

RESULTSIn the stepwise Cox proportional hazard model, the independent prognostic factors for PCa progression after endocrine therapy were found to be Gleason score (P < 0.01) and clinical stages (P < 0.01). The hazard of PCa progression after endocrine therapy increased 2.126 times that of the baseline for each unit of increase in Gleason score, and 6.625 times for each unit of increase in the clinical stage. The pretreatment PSA level was correlated with both clinical stages (P < 0.01) and Gleason score (P < 0.01).

CONCLUSIONClinical stages and Gleason score were important factors that influenced the progression-free survival time after endocrine therapy in this cohort of PCa patients.

OBJECTIVETo observe the clinical effect of the treatment for complex fractures of the tibial plateau through the application of the external fixator and the locking plate.

METHODSFrom Feb. 2006 to Oct. 2008,12 patients with tibial plateau fractures were treated with external fixator and locking plate included 8 males and 4 females with an average age of 38 years ranging from 23 to 59. According to Schatzker type, 7 cases were type V and 5 cases were type VI. Using an anteromedial incision and an anterolateral approach, the locking plate were fixed in the tibia lateral. The collapse and height lossing of tibial plateau was observed through X-ray film before and after operation. The function of knee joint was evaluated according to HSS scoring.

RESULTSThese patients were followed up for 4 to 18 months (means 9.79 months). Eleven cases had bone primary union,and 1 delayed union. No deep phlebothrombosis and osteofascial compartment syndrome occurened. The average healing time was 3.1 months. Between the preoperative and postoperative X-ray film there were no second stage depression fracture of the tibial plateau,postoperative reduction loss and bad alignment. The range of knee flexion was 90 degrees to 110 degrees. The HSS knee functional scoring was(75.50 +/- 10.01)scores after operation and (21.50 +/- 11.68) scores before operation.

CONCLUSIONThe treatment with the external fixator and the locking plate for complex fractures of the tibial plateau could provid continuous stability of fixation,prevent the fracture from second stage displacement and the knee force line change, protect the soft-tissue around the knee, reduce the postoperative complications. The knee joint function is satisfied.

Purpose: Triple-negative breast cancer (TNBC) is highly malignant and has poor prognosis and a high mortality rate. The lack of effective therapy has spurred our investigation of new targets for treating this malignant cancer. Here, we identified RON (macrophage-stimulating 1 receptor) and MET (MET proto-oncogene, receptor tyrosine kinase) as a prognostic biomarker and therapeutic targets for potential TNBC treatment. Materials and Methods: We analyzed RON and MET expression in 187 primary TNBC clinical samples with immunohistochemistry. We validated the targeted therapeutic effects of RON and MET in TNBC using three tyrosine kinase inhibitors (TKIs): BMS-777607, INCB28060, and tivantinib. The preclinical therapeutic efficacy of the TKIs was mainly estimated using a TNBC xenograft model. Results: Patients with TNBC had widespread, abnormal expression of RON and MET. There was RON overexpression, MET overexpression, and RON and MET co-overexpression in 63 (33.7%), 63 (33.7%), and 43 cases (23.0%), respectively, which had poor prognosis and short survival. In vivo, the TKI targeting RON ant MET inhibited the activation of the downstream signaling molecules, inhibited TNBC cell migration and proliferation, and increased TNBC cell apoptosis; in the xenograft model, they significantly inhibited tumor growth and shrank tumor volumes. The TKI targeting RON and Met, such as BMS-777607 and tivantinib, yielded stronger anti-tumor effects than INCB28060. Conclusion RON and MET co-overexpression can be significant pathological characteristics in TNBC for poor prognosis. TKIs targeting RON and MET have stronger drug development potential for treating TNBC.

The use of cosmetics in the crowd has the long-term characteristics. The adverse reactions of cosmetics reported in other country in the world suggest that human patch tests and short-term human using test may not be sufficient to evaluate the safety of high-risk new cosmetic raw ingredients, and long-term human using test should be conducted for evaluation. Therefore, this article reviews the key factors that affect long-term human trial trials, such as site of use, single-use amount, frequency of use, duration of use, and subject conditions, providing supportive evidence for standardized safety evaluation standards for long-term human using test of cosmetics.

Objective: To analyze the migration of the HIV/AIDS cases and related factors in Liangshan Yi autonomous prefecture (Liangshan). Methods: According to HIV/AIDS Comprehensive Response Information Management System of China Information System for Disease Control and Prevention, a total of 28 772 HIV/AIDS cases who had follow-up records in Liangshan in 2020 were included in the survey. The migration of the HIV/AIDS cases was described and the related factors were analyzed using multiple logistic regression models, and the migration destinations of the HIV/AIDS cases were mapped. Results: Among the 28 772 HIV/AIDS cases, 20.89% (6 010/28 772) had migration in 2020. Multivariate logistic regression analysis showed that among the HIV/AIDS cases, the migration related factors included being aged 15-24 years (compared with being aged 0-14 years, OR=2.74, 95%CI:2.04-3.69) and ethnic group (compared with Han ethnic group, OR=2.44, 95%CI:2.19-2.72), having education level of junior high school (compared with having education level of primary school or below, OR=1.25, 95%CI:1.14-1.38), being unmarried (compared with being married, OR=1.29, 95%CI:1.20-1.39), being engaged in business services (compared with being engaged in farming, OR=1.96, 95%CI:1.31-2.92), receiving antiviral treatment <1 year (compared with receiving antiviral treatment >3 years, OR=1.42, 95%CI:1.26-1.61), having recent CD4⁺T lymphocytes (CD4) counts >500 cells/μl (compared with having recent CD4 counts <200 cells/μl, OR=1.15, 95%CI:1.03-1.29). The geographical distribution maps showed that among all cities in Sichuan, Xichang (13.26%, 797/6 010) and Chengdu (10.12%,608/6 010) were the main migration destinations of the HIV/AIDS cases, and the provinces outside Sichuan where the HIV/AIDS cases would like to migrate to were mainly Guangdong (18.19%, 1 093/6 010) and Zhejiang provinces (7.67%, 461/6 010) in 2020. The HIV/AIDS cases who migrated where Liangshan, within Sichuan province, and to other provinces accounted for 27.67% (1 663/6 010), 15.34% (922/6 010) and 56.99% (3 425/6 010), respectively. Conclusions: More attention should be paid to the mobility characteristics and the classification management of HIV/AIDS cases according to their characteristics in Liangshan. Timely access to information on changes in the place of work and residence of HIV/AIDS cases should be warranted when they have migration. Good referrals and management for mobility of HIV/AIDS cases in different places should be made to reduce loss to follow-up and improving interventions.

A new type of L. Bulgaricus microcapsule was prepared to improve stability and resistance of L.Bulgaricus probiotics in harsh environments. An optimal method of preparation of L. Bulgaricus microcapsule is as follow. L. Bulgaricus was mixed with 3% alginate solution. The concentration of bacterial suspension was 1×10⁹ cfu·mL^-1. The mixture was microencapsulated by extrusion into 2% CaCl₂ solution with a dispensing equipment. After 30 min solidification, the gel beads were lyophilized to obtain L.Bulgaricus microcapsules. The microencapsulation technology was aimed to improve the stability and survival rate of L. Bulgaricus. The microcapsule was spherical with uniform particle size and intact structure. The tolerance of acid, high temperature, high humidity and the long-term stability of freeze-dried powder and microcapsule were evaluated. The results indicated that microencapsulation technic could greatly improve stability and resistance of L. Bulgaricus probiotics in harsh environments.

This study explored the mechanism of Shenling Baizhu Powder(SLBZP) in the prevention and treatment of type 2 diabetes from the perspective of flora disorder and chronic inflammation. Fifty rats were randomly divided into normal control group, model control group, low-dose SLBZP group, medium-dose SLBZP group, and high-dose SLBZP group, with 10 rats in each group. The rats of 5 weeks old were administrated by gavage with ultrapure water and different doses of SLBZP decoction. The basic indicators such as body weight and blood glucose were monitored every week, and stool and intestinal contents were collected from the rats of 9 weeks old for 16 S rRNA sequencing and metabolomic analysis. An automatic biochemical analyzer was used to measure the serum biochemical indicators, ELISA to measure serum insulin, and chipsets to measure leptin and inflammatory cytokines. The results showed that SLBZP reduced the body weight as well as blood glucose, glycosylated hemoglobin, and lipid levels. In the rats of 9 weeks, the relative abundance of Anaerostipes, Turicibacter, Bilophila, Ochrobactrum, Acinetobacter, and Prevotella decreased significantly in the model control group, which can be increased in the high-dose SLBZP group; the relative abundance of Psychrobacter, Lactobacillus, Roseburia and Staphylococcus significantly increased in the model control group, which can be down-regulated in the high-dose SLBZP group. The differential metabolites of intestinal flora included 4-hydroxyphenylpyruvic acid, phenylpyruvic acid, octanoic acid, 3-indolepropionic acid, oxoglutaric acid, malonic acid, 3-methyl-2-oxovaleric acid, and methylmalonic acid. Moreover, SLBZP significantly lowered the levels of free insulin, insulin resistance and leptin resistance in rats. The variations in the serum levels of interleukin 1β(IL-1β) and monocyte chemoattractant protein-1(MCP-1) showed that SLBZP could alleviate chronic inflammation in rats. In conclusion, SLBZP can regulate intestinal flora and metabolites and relieve chronic inflammation to control obesity and prevent type 2 diabetes.
