Nurses should pay more attention to nursing of patients with infections and infectious diseases, and carry out effective hygiene management and infection care to minimize the infection rate of infectious disease pathogens. This article briefly analyzed the ethical issues of infection and infectious disease care, and explored specific nursing methods for infection and infectious diseases, aiming to provide assistance and reference for modern infection and infectious disease care in China.

Objective To explore the relationship between air pollutants and late spontaneous abortion in valley cities, and to establish the dose-response relationship of exposure. Methods A retrospective case-control study was conducted. The data of pregnant women with late spontaneous abortion from January 2018 to December 2019 in the department of gynecology and obstetrics of two tertiary hospitals in a city were collected, and pregnant women who delivered normal full-term infants in the same hospital in the same period were selected as the control group according to the matching ratio of 1:4, to control the influence of maternal age and pregnancy times. According to the last menstruation, the exposure dose of each pregnant woman during different periods of pregnancy (early and second trimester) was evaluated, and the relationship model between exposure dose of air pollutants and late spontaneous abortion was established by Logistic regression analysis. Results In total 84 pregnant women with late spontaneous abortion and 336 healthy full -term infants were included in the study. It was found that parity, cesarean section, last menstrual season, menstrual cycle, pregnancy complications, and pregnancy complications were the confounding factors of late spontaneous abortion. There was significant difference in only CO exposure level in early pregnancy between late abortion and control group (P < 0.001), but in PM助 PM25, S02, CO, N02, and 03 exposure levels in the second trimester of pregnancy (P < 0.05). After controlling for the related confounding factors, the exposure of PMLo(OR = 1.033), PM25 (OR=1.079), S02 (OR=l»056), CO (OR=5.851), and N02 (OR=1.096) in the second trimester of pregnancy were risk factors of late abortion. Conclusion Exposure to air pollutants in valley cities in the second trimester will increase the risk of late abortion. [ABSTRACT FROM AUTHOR]

Breast cancer is the highest incidence and mortality of malignant tumor in women. Recurrence and distant metastasis are the main cause of death. Zoledronic acid (ZOL) has the potential to inhibit bone resorption characteristics mediated by osteoclast, which not only could suppress tumor cell proliferation and start the apoptosis of tumor cells, but also might interfere the adhesion of cancer cells to bone matrices, thereby could inhibit the migration and invasion of tumor cells. In some preclinical studies zoledronic acid has been demonstrated to have the direct anti-tumor effects on breast cancer. There are different therapeutic effects in treatment with zoledronic acid between the premenopausal and post-menopausal patients with breast cancer. This review summarized basic and clinical research progress of the anti-tumor differentiation effect of zoledronic acid in breast cancer. [ABSTRACT FROM AUTHOR]

Objective To construct the lentivirus vector of human SND1 gene and to screen the human ovarian cancer cell line SKOV3 which can stably expresses SND1 protein. Methods The fragment of FLAG-SND1 was cloned from pC-MV-FLAG-SND1 plasmid, and then was inserted into lentivirus vector pLVX-IRES-Hyg. The lentivirus expression vector pLVX-FLAG-SND1 was established and was transiently transfected into 293T cells for 48 h. Western blotting was employed to determine SND1 expression. Then the lentivirus expression vector was co-transfected into 293T cells with packaging plas-mids to obtain the recombinant lentivirus carrying FLAG-SND1.The lentivirus was collected to infect SKOV3 cells. After 48 h of infection, 1 μg/mL hygromycin B was used to screen the infected cells, so as to obtain a cell line with stable ex-pression of SND1 protein. The expression level of SND1 was detected by Western blotting. Results Double restriction en-zyme digestion and DNA sequencing demonstrated the lentivirus expression vector pLVX-FLAG-SND1 was constructed. The recombinant plasmids were transiently transfected into 293T cells, and the expression level was significantly higher than that of the wild-type SKOV3 cells (P<0.01).In the SKOV3 cells which stably expressed SND1 after infection and drug screening, the expression of SND1 was significantly higher than that of the wild-type SKOV3 cells (P<0.01).Conclusion The SND1 gene lentivirus vector pLVX-FLAG-SND1 is constructed successfully and we screen the SKOV3 cell line stably overexpressing SND1 via lentivirus system.
