Objective To explore the predictive value of serum proprotein convertase subtilisin/kexin type 9(PCSK9)and proprotein convertase subtilisin/kexin type 9(CTRP6)in pregnant women undergoing threatened abortion and fetal protection treatment for pregnancy outcomes.Methods Eighty pregnant women with threatened abortion who were treated in the Second Affiliated Hospital of Shaanxi University of Chinese Medicine from August 2021 to May 2022 were selected as the study subjects.According to the pregnancy outcome,they were grouped into the good pregnancy outcome group(n=62)and the bad pregnancy outcome group(n=18),while another 60 pregnant women with normal pregnancy tests in the hospital were selected as the control group.The serum levels of PCSK9,CTRP6,progesterone and β-human chorionic gonadotropin(β-HCG)were measured by enzyme-linked immunosorbent assay(ELISA).Pearson method was applied to analyze the correlation between serum PCSK9,CTRP6 levels and progesterone and β-HCG levels.Multivariate Logistic regression analysis was applied to analyze the factors affecting the pregnancy outcomes of pregnant women with threatened abortion.The predictive value of serum PCSK9 and CTRP6 on pregnancy outcome of pregnant women with threatened abortion and pregnancy protection treatment was analyzed by the receiver operating characteristic(ROC)curve.Results The level of progesterone(45.65±3.48,38.29±3.54 and 31.56±4.11 nmol/L),β-HCG(32 056.56±4 244.54,23 642.32±3 897.67 and 11 375.56±3 454.35 mIU/L)and CTRP6(436.53±36.23,328.44±31.06 and 277.86±25.56 ng/ml)in control group,good pregnancy outcome group and bad pregnancy outcome group decreased gradually,while the level of PCSK9(64.22±10.35,82.24±13.33 and 114.56±17.67 ng/ml)in the control group,the good pregnancy outcome group and the bad pregnancy outcome group increased gradually,with statistically significant differences(F=129.231,199.334,244.007,111.297,all P＜0.05).Pearson method showed that serum PCSK9 was negatively correlated with progesterone and β-HCG levels(r=-0.545,-0.514,all P＜0.05),and serum CTRP6 was positively correlated with progesterone and β-HCG levels(r=0.567,0.496,all P＜0.05).Multivariate Logistic regression analysis showed that the high level of PCSK9 was an independent risk factor for pregnancy outcome of threatened abortion and fetal protection treatment,and the high level of CTRP6,progesterone and β-HCG were independent protective factors for pregnancy outcome of threatened abortion and fetal protection treatment(P＜0.05).ROC results showed that the area under the curve(AUC)of serum PCSK9 and CTRP6 levels for patients with adverse pregnancy outcomes in the prediction of threatened abortion and fetal protection treatment was 0.843 and 0.849,respectively.The AUC predicted by the combination of the two was 0.941,which was better than that predicted by each individual(Z=1.725,1.882,P＜0.05),with a specificity and a sensitivity of 85.48%,94.44%,respectively.Conclusion The serum PCSK9 level of pregnant women undergoing threatened abortion and fetal protection treatment was obviously increased,and the level of CTRP6 was obviously reduced.This study indicated both have important value in predicting the pregnancy outcomes of pregnant women undergoing threatened abortion and fetal protection treatment.

Objective:This study aims to investigate the relationship between high-risk human papillomavirus (HR-HPV) infection and the composition of vaginal microecology. It will analyze the efficacy of integrated traditional Chinese and Western medicine intervention in treating HR-HPV infection, as well as the effects of this combined approach on vaginal microecology. Additionally, the study seeks to identify new methods to inhibit the malignant progression of cervical intraepithelial lesions.Methods:A prospective study was conducted involving 100 patients with HR-HPV infection who visited the Department of Gynecology, The Second Affiliated Hospital of Shaanxi University of Chinese Medicine from April to June 2023. The participants were randomly divided into a control group and an observation group, with 50 patients in each group using a random number table method. The control group received interferon treatment, while the observation group was treated with a combination of interferon and Yanfukang Lotion. High-throughput DNA sequencing of vaginal secretions was conducted to compare the differences in pre- and post-treatment vaginal microecological composition and the rate of HR-HPV clearance between the two groups. Results:In the observation group, both the diversity index and the abundance of vaginal microecology showed significant improvements compared with the control group, particularly in the abundance of dominant Lactobacillus species. These differences were statistically significant ( R = 0.124, 0.304, 0.030, all P < 0.05). The rates of HR-HPV clearance and overall effective rate (clearance + effective) in the observation group were 44% (22/50) and 68% (34/50), respectively, which were significantly higher than those in the control group [20% (10/50), 32% (16/50), χ2 = 12.98, both P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (χ2 = 1.76, P > 0.05). Conclusion:The combination of interferon and Yanfukang Lotion effectively treats HR-HPV infection by regulating the composition of vaginal microecology. This approach shows considerable efficacy and good safety, indicating its potential for further clinical application.
