In the study, the ovarian cancer cell lines (BT 549) were rolled into a control group (normal culture-defined as BT549/NC) and a response group (transfected with non-coding RNA LINC00857 cultured cells-defined as BT 549YAP cells). The expression and proliferation ability of the transcription factor YAP-TEAD in the two groups of cancer cells were analyzed and compared. The results showed that the YAP-TEAD expression rate was the highest in Bt549 cells; the YAP content grade (0.18) in BT 549-YAP cells was lower than BT 549/NC (0.2) after transfection (P< 0.05); and the apoptotic rate of the response group (80%) was higher than that of the control group (25%) after the intervention. With the extension of culture time, the expression of CCN1 mRNA decreased (P< 0.05), and CCN2 mRNA increased (P< 0.05). After 12, 24, 36, and 48 hours, the apoptosis rate of the reaction group at different time points was higher than that of the control group (P< 0.01). When YAP-TEAD was down-regulated, the in vitro proliferation ability of BT 549-YAP cells was weakened compared with BT 549/NC and parental cells.

The population characteristics of TB/HIV dual infection and mutation of drug-resistant genes were discussed. It was found that TB patients aged 20-40 years had the highest HIV infection rate, followed by those aged over 40 years. The rate of HIV infection in smear-negative TB patients was higher than that in smear-positive TB patients. HIV/AIDS patients aged 20-40 had the highest TB infection rate. In addition, men had higher rates of HIV than women, and married people had lower rates of HIV than single people. Mycobacterium tuberculosis (MTB) had the highest resistance to isoniazid (42.86%), followed by ofloxacin (34.82%), streptomycin (33.81%), and rifampicin (32.15%).
