Method: Collected patients with mental illness who were hospitalized in our hospital from January 2020 to June 2021, and selected as the research subjects patients with psychiatric disorders who were treated with 2 kinds of commonly used antipsychotic drugs;and collected 3 ml of venous blood before treatment and one month after treatment for renal function tests;observed the changes of renal function indexes before and after treatment. Results: In the collected 694 patients with mental illness, before using antipsychotic drugs, the renal function indexes were BUN: 4.42 ± 1.92 mmol/l;Cr: 70.97 ± 16.92 μmol/l;CCr: 88.37 ± 21.07 ml/min;β2-MG: 1.67 ± 0.61 mg/L;UA: 359.90 ± 112.82 μmol/l;CYS-C: 0.92 ± 0.24 mg/L. One month after using antipsychotics, BUN: 3.77 ± 1.37 mmol/l;Cr: 70.46 ± 16.71 μmol/l;CCr: 87.78 ± 20.63 ml/min;β2-MG: 1.75 ± 0.64 mg/L;UA: 332.53 ± 91.48 umol/l;CYS-C: 0.92 ± 0.24 mg/L;the renal function indexes of urea nitrogen, β2 microglobulin, uric acid and other items all changed significantly. The differences before and after treatment were statistically significant, P < 0.01. Conclusion: Several commonly used antipsychotic drugs have a greater impact on the renal function of patients with mental illness. During the treatment, the changes in renal function should be monitored regularly, if severe renal damage is found, the treatment plan or dosage should be adjusted in time to avoid endangering life.展开更多

Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.展开更多
