Objective:To evaluate the application value of preconceptional laparoscopic cervical cerclage(LCC)in improving the pregnancy outcomes with cervical incompetence(CIC).Methods:Clinical data of 112 pa-tients with CIC who underwent preconceptional LCC in The First Affiliated Hospital of Zhengzhou University from July 1,2014 to May 31,2023 were retrospectively reviewed.The surgical indications of preconceptional LCC in-cluded:failed transvaginal cervical cerclage(TCC)(42 patients),history of cervical surgery+failed TCC(7 pa-tients),unsuitability for TCC(10 patients)and strong request from patients(53 patients).The surgical situation and pregnancy outcome of preconceptional LCC were analyzed,and the gestational age of delivery before and af-ter preconceptional LCC surgery and different surgical indications were compared in postoperative delivery pa-tients who underwent preconceptional LCC.Results:The median operation time of 112 patients was 65.5 min,the median intraoperative blood loss was 10.0 ml,and there were no intraoperative complications.The postopera-tive hospital stay was 2.9±0.6 d.108 cases were followed up after surgery,with 77 cases of pregnancy and de-livery after LCC.A total of 205 deliveries were made before surgery,and 81 deliveries were made after surgery.Successful postoperative deliveries(delivery after 28 weeks)were 78(96.3% ),with an average gestational age 37.4±1.7 weeks.The preterm birth rate was 16.7%,term birth rate was 83.3% .The delivery rate at≥28 weeks after preconceptional LCC was significantly higher than the previous delivery rate of pre pregnancy LCC(96.3% vs.10.7%,P<0.05),and the gestational age was significantly prolonged(36.4±5.5 weeks vs.19.8±7.5 weeks,P<0.05).The postoperative delivery gestational week of preconceptional LCC with different surgical indi-cations was significantly later than the previous delivery gestational week of pre pregnancy LCC(P<0.05),ex-cept for the indication of unsuitability for TCC(P>0.05).Conclusions:Preconceptional LCC surgery is highly safe and can effectively prolong the gestational age and improve pregnancy outcomes in patients with CIC.It can be an effective treatment method for patients with a history of TCC failure.

Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids. Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD. Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas low-density lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different. Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Objective To investigate the risk factors of nausea and vomiting during postoperative chemotherapy in patients with gastric cancer and to construct a corresponding risk prediction model.Methods This study collected gastric cancer patients from the first affiliated hospital of Hunan university of traditional Chinese medicine from February 2020 to February 2021 as a modeling set to explore the risk factors of nausea and vomiting during chemotherapy in gastric cancer patients after surgery,and constructed a corresponding risk prediction models.The data were collected from March 2021 to February 2022(Year 1),March 2022 to February 2023(Year 2),and March 2023 to February 2024(Year 3)as a validation set,which was used to validate the risk prediction model constructed by the modeling set.The incidence of vomiting during chemotherapy was detected in the modeling set.The univariate and multivariate Logistic regression to analyze the risk factors of nausea and vomiting during chemotherapy in gastric cancer patients after surgery,and constructing a corresponding risk prediction model.The accuracy of the corresponding risk prediction model was validated using receiver operating characteristic curve(ROC)with a validation set from March 2021 to February 2024.Results A total of 112 patients were included in the modeling set,of which 75 patients(66.96％)did not have nausea and vomiting during postoperative chemotherapy and were included in the control group,while 37 patients(33.04％)developed nausea and vomiting during postoperative chemotherapy and were included in the observation group.The univariate analysis showed that age,gender,history of alcohol consumption,history of motion sickness,frequency of chemotherapy,history of chemotherapy-related nausea and vomiting,history of vomiting during pregnancy,Pittsburgh sleep quality index(PSQI)and psychological expectation of post chemotherapy nausea and vomiting were related to the occurrence of nausea and vomiting during postoperative chemotherapy(P＜0.05).Logistic regression analysis showed that age,gender,history of motion sickness,chemotherapy frequency,history of vomiting during pregnancy,PSQI,and psychological expectation of postoperative nausea and vomiting in gastric cancer patients were risk factors for nausea and vomiting during postoperative chemotherapy(P＜0.05).A risk prediction model based on Logistic regression to identify statistically significant factors.Internal validation of the model was conducted by the Bootstrap method,with an area under curve(AUC)of 0.71(95％CI:0.71-1.00)for the first year validation set,0.69(95％CI:0.58-0.96)for the second year validation set,and 0.66(95％CI:0.54-0.95)for the third year validation set.Conclusion The Age,gender,history of motion sickness,frequency of chemotherapy,history of vomiting during pregnancy,PSQI and psychological expectation of postoperative nausea and vomiting during chemotherapy are risk factors for nausea and vomiting during postoperative chemotherapy.The risk prediction model for nausea and vomiting during chemotherapy in gastric cancer patients constructed based on the above factors has good predictive performance and can provide reference for clinical treatment of gastric cancer patients.
