Objective To explore the apoptosis of alveolar epithelial cell(AEC)and the dynamic changes of Caspase-3 mRNA and Bax and Bcl-2 expression in premature rat with hyperoxia-induced chronic lung disease(CLD).Methods Sixty premature rats within 1 day after birth were randomly divided into 2 groups:hyperoxia group(n=30)and control group(n=30).Hyperoxia-induced premature rat CLD models were prepared,and situ nick end-labeling(TUNEL),reverse transcription polymerasechain reaction(RT-PCR)and immunohistochemical technique were used to determine apoptosis index(AI)of AEC and the expressions of Caspase-3 mRNA and Bax and Bcl-2 proteins in lung tissues at 1,3,7,14 and 21 d after birth.Results Compared with control group,in the hyperoxia group,on the third day after exposured to hyperoxia,the AI of AEC and the expressions of Caspase-3 mRNA and Bax began to increase,and the expression of Caspase-3 mRNA was kept at high level on 7-21 d.The expression of Bcl-2 began to decrease on 7 d,and significantly decreased on 7-21 d.AI of AEC was positively correlated with the expression of Caspase-3 mRNA and Bax,and negatively with the expression of Bcl-2.Conclusions Hyperoxia may induce the increased expression of Caspase-3 mRNA,which might result in the abnormal expression of Bax and Bcl-2 in lung tissues and their imbalance,which might be one of the underlying mechanisms of apoptosis of AEC in premature rats with CLD.

Prostate cancer is one of the common malignant tumors of male urogenital system, and the incidence of prostate cancer in China has increased significantly in the past decade. At present, endocrine therapy based on androgen blockade is the main method of clinical treatment except radical surgery and radiotherapy/chemotherapy for prostate cancer. However, the clinical benefit can only be obtained in the early stage of treatment, and nearly 90% of patients will develop to the castration resistance, and among them, nearly 90% of patients will have bone metastasis. The quality of life decreases sharply with the progression of disease for patients. In addition to the androgen signal pathway, studies have shown that many other oncogenic signal pathways have involved in the development of castration resistance, including classic cancer signaling pathways, immune and inflammatory signaling pathways, etc. Understanding the mechanism of androgen independent signal pathway in the formation of castration resistance will help to understand the off-target effect of androgen blocking therapy and introduce new treatment targets or strategies to get rid of the "no drug available" dilemma for clinical treatment of castration resistance.

Objective:
To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality.
Methods :
The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model.
Results:
Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death.
Conclusions
The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

OBJECTIVETo extract RNA from Pinellia ternata and lay a foundation for studying the formation mechanism of P. ternata.
METHODBy modifying the method recommended by Guanidinium for extracting total RNA from plant tissues rich in phenolic and polysaccharidic compounds, a simple and convenient method for extraction of total RNA from the tubers, stems and leaves of P. ternate containing abundant polyphenols and polysaccharides was established. High concentrated p-mercaptoethanol was added in the RNA extracted buffer to remove polyphenols, phenol and chloroform were used to eliminate proteins, and isopropanol and sodium acetate were used to precipitate polysaccharides.
RESULTThe A260/A230 value of RNA extracted with improved method were all over 2.0 and the values of A260/A280 were between 1.7 and 2.0. The electrophoresis bands were cleared on agarosegel and integrity of RNA was good.
CONCLUSIONThe results showed that RNA obtained from the tubers, stems and leaves of P. ternate with this method had high purity and quality and could be used in molecular biological research, as DDRT-PCR and reverse Northern blotting analysis directly. This method is simple, economic, stable performance, and has a good repeatability as well as is suitable for extracting total RNA of medicinal plants with high concentrations of phenolics and polysaccharides.
