Objective:To investigate the high risk factors,diagnostic accuracy of ultrasonography and pregnan-cy outcomes of umbilical cord wrapped around the neck for≥4 loops.Methods:The clinical data of 64 pregnant women with umbilical cord around the neck for≥4 loops(the group with umbilical cord around the neck≥4 loops)in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2011 to February 2024 were retrospectively analyzed.At the same time,80 cases with umbilical cord around the neck for 1-2 loops(the group with umbilical cord around the neck 1-2 loops)were randomly selected as the controls.General information,clinical manifestations,ultrasound diagnosis and other data of the two groups were collected.The risk factors of umbilical cord around the neck≥4 loops and diagnostic accuracy of ultrasonography were ana-lyzed with univariate and multivariate Logistic regression analysis,and the pregnancy outcomes were compared between the two groups.Results:①The incidence of pregnancy,abortion,delivery and history of cesarean sec-tion were lower in the group with umbilical cord around the neck ≥4 loops than those in the group with umbilical cord around the neck 1-2 loops.The incidence of consciously abnormal fetal movement,abnormal umbilical ar-tery systolic/diastolic(S/D)ratio,abnormal fetal heart rate monitoring(NST)and fetal distress were higher in the group with umbilical cord around the neck≥4 loops than those in the group with umbilical cord around the neck 1-2 loops,and the differences were statistically significant(P＜0.05).②Multivariate Logistic regression analysis showed that polyhydramnios and excessively long cord were independent risk factors for umbilical cord around the neck≥4 loops(OR＞1,P＜0.05).③When the time between ultrasound diagnosis and the operation was 2 days,the consistency rate between ultrasound diagnosis of umbilical cord around the neck≥4 loops and intrao-perative diagnosis was the highest,and the difference was statistically significant with＞3 days(46.2％vs.6.30％,P＜0.05).Compared with umbilical cord around the neck 3 loops,ultrasound diagnosis of umbilical cord loops around the neck at 4 or 5 loops had a higher consistency rate with intraoperative diagnosis,and the differ-ence was statistically significant(P＜0.05).④The incidence of premature delivery,neonatal asphyxia and admis-sion to neonatology in the group with umbilical cord around the neck ≥4 loops were higher than those in the group with umbilical cord around the neck 1-2 loops,and the difference was statistically significant(P＜0.05);and the gestational week and birth weight of newborns were significantly lower(P＜0.05).Conclusions:Polyhydramnios and excessively long cord are high risk factors for umbilical cord around the neck≥4 loops.The closer the ultra-sound diagnosis is to the time before cesarean section and the more times the umbilical cord is around the neck in ultrasonic diagnosis,the higher the diagnostic accuracy.Fetal outcomes with umbilical cord around the neck≥4 loops are worse.

OBJECTIVE To observe the efficacy of cetrorelix combined with aspirin in preventing early-onset ovarian hyperstimulation syndrome （OHSS）. METHODS A retrospective analysis was conducted on clinical data from 38 early-onset OHSS patients， who received treatment in our hospital from January 1st to July 1st， 2022. These patients were divided into intervention group （19 cases） and control group （19 cases） according to the therapy regimen. On the first day after oocyte retrieval surgery， the control group was given aspirin enteric-coated tablets 100 mg orally until menstruation began. The intervention group was given cetrorelix for injection 0.25 mg subcutaneously， for consecutive 3 days+aspirin enteric-coated tablets （same usage and dosage as the control group）. The first luteal phase， the degree of OHSS， and the ovarian volume， ascites volume， serum estradiol （E2）， white blood cell count （WBC）， hematocrit （HCT）， neutrophil ratio （NEUT%）， D-dimer （DD）， prothrombin time （PT）， fibrinogen （Fib） after oocyte retrieval surgery were observed and measured in 2 groups. RESULTS The first luteal phase was significantly shorter， and the proportions of median and severe OHSS cases were significantly lower in the intervention group compared to the control group （P＜0.05 or P＜0.01）. After oocyte retrieval surgery， the intervention group showed significantly lower ovarian volume， ascites volume， serum E2， WBC， NEUT%， HCT， DD and Fib compared to the control group， but PT of intervention group was signiticantly higher than that of control group （P＜0.05）. CONCLUSIONS Cetrorelix combined with aspirin is more effective in preventing early-onset OHSS than aspirin alone.

Objective:To analyze the effect of long-term care insurance on the incidence of falls in old people with disability, and the modification effect of different living arrangements.Methods:Based on the discharge diagnosis records of the hospitalization in urban residents who applied for long-term care insurance in Chengdu from July 2014 to June 2021, those who received long-term care insurance were selected as the intervention group and those who received no long-term care insurance were selected as the control group, the changes in the incidence of falls before and after the long-term care were analyzed using difference-in-differences method, and the modification effects of different living arrangements were explored using stratified analysis.Results:Long-term care insurance significantly reduced the risk for monthly incidence of falls in older adults [average treatment effects on treated (ATT) = -1.21% (95% CI: -1.82%--0.60%)], and the effect increased over time (ATT=-1.26%, 95% CI: -1.93%--0.59%). Long-term care insurance had a significant effect on reducing the incidence of falls in old people living with spouses/family members (ATT=-0.92%, 95% CI: -1.47%--0.37%) and in nursing facilities/hospitals (ATT=-2.10%, 95% CI: -3.81%--0.40%), but it had no significant effect in those living alone. Conclusions:Long-term care insurance can effectively reduce the incidence of falls in old people with disability, showing a positive effect. Living with family members or in nursing facilities/hospitals has a modification effect of the implementation of long-term care insurance policy. It is necessary to pay attention to key populations in the future and expand the coverage of long-term care insurance.
