Objective:To investigate the effect of "four-staff co-management" follow-up mode on risk factor control and medium-term prognosis improvement in patients with coronary heart disease after percutaneous coronary intervention (PCI).Methods:This was a intervention study. Patients with coronary heart disease who were admitted to the Xiamen Cardiovascular Hospital of Xiamen University from June 2021 to January 2022 and successfully discharged after PCI were included. According to the different types of follow-up after discharge, patients were divided into the traditional follow-up group and the "four-staff co-management" follow-up group. The "four-staff co-management" follow-up mode means that specialists, specialist managers in third-level A hospitals and general practitioners and health managers in basic hospitals were jointly responsible for post-discharge follow-up of PCI patients. Baseline clinical data were collected. The primary endpoints were the rate of compliance of coronary heart disease risk factor control at 12 months after surgery, the rate of secondary surgery, and the incidence of mid-term major adverse cardiovascular and cerebrovascular events (MACCE). Unplanned secondary PCI included symptom-driven secondary PCI and asymptomatic secondary PCI. MACCE includes myocardial infarction, hospitalization for heart failure, stroke, major bleeding, all-cause death, and composite endpoints including these events.Results:A total of 2 181 patients were enrolled, including 1 097 patients in the traditional follow-up group and 1 084 patients in the "four-staff co-management" follow-up group. At baseline, there were no statistically significant differences in gender, age, discharge diagnosis, co-existing diseases, echocardiographic indexes, and coronary artery lesions between the two groups (all P>0.05). There were no significant differences between the two groups in total PCI stent length, maximum internal diameter of stent, proportion of patients using drug balloon, proportion of patients with a planned second surgery during hospitalization, and discharge with drugs (all P>0.05). Twelve months after PCI, the reduction in HbA1c and low-density lipoprotein cholesterol was greater in the "four-staff co-management " follow-up group than that in the traditional follow-up group (all P<0.05), and the rate of reaching the standard for low-density lipoprotein cholesterol was higher than that in the traditional follow-up group ( P=0.001), but there was no statistical significance between the two groups for blood pressure and blood glucose (all P>0.05). During the follow-up period, the proportion of symptom-driven second operation patients was lower in the "four-staff co-management" follow-up group than that in the traditional follow-up group ( P<0.001), and there was no significant difference in the proportion of asymptomatic second operation patients between the two groups ( P=0.191). The proportion of hospitalized patients with heart failure in the "four-staff co-management" follow-up group was lower than that in the traditional follow-up group ( P=0.029), and there was no significant difference in the proportion of myocardial infarction, cerebral infarction, cerebral hemorrhage, massive hemorrhage, death and complex endpoint events between the two groups (all P>0.05). Conclusion:The "four-staff co-management" follow-up mode can effectively improve the control of risk factors and medium-term prognosis in patients with coronary heart disease after PCI.

Objective:To investigate the effect of pre-pregnancy body mass index (BMI) on the cumulative live birth rate (CLBR) and perinatal outcomes in women with polycystic ovary syndrome (PCOS) undergoing first in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI).Methods:The clinical data of 1 013 patients with PCOS who received first IVF/ICSI treatment in Reproductive Medicine Center, Henan Provincial People′s Hospital from January 2017 to June 2020 were retrospectively analyzed. According to BMI China standard, they were divided into: normal weight group (18.5≤BMI<24.0 kg/m 2, 388 cases), overweight group (24.0≤BMI<28.0 kg/m 2, 367 cases), obese group (BMI≥28.0 kg/m 2, 258 cases). The effect of BMI on CLBR was analyzed by univariate analysis, multivariate logistic regression analysis and smooth curve fitting. The role of homeostasis model assessment of insulin resistance index (HOMA-IR) in the process of BMI on CLBR was analyzed by mediation analysis. Results:Among three groups, female age, basal level of follicle stimulating hormone, type of infertility and ovulation induction regimens were similar (all P>0.05). The infertility duration, basal testosterone level, HOMA-IR, the ovulation induction time and the total gonadotropin dosage increased with BMI (all P<0.01), anti-Müllerian hormone, basal luteinizing hormone level, the number of retrieved oocytes and available embryos decreased with BMI (all P<0.05). CLBR decreased with BMI increasing [84.08% (301/358) vs 74.26% (251/338) vs 71.88% (161/224); P<0.001]. The incidence of hypertensive disorder in pregnancy was highest in obese group, while premature rupture of membranes rate, premature delivery rate, low birth weight rate and macrosomia birth rate were the lowest in normal weight group. After adjusting for confounding factors, both smooth curve fitting and multiple logistic regression analysis revealed a significant trend: CLBR declined with increasing BMI ( OR=0.93, 95% CI: 0.89-0.97; P=0.002), with a reduction of 41% ( OR=0.59, 95% CI: 0.39-0.91; P=0.020) in overweight group, and a reduction of 48% ( OR=0.52, 95% CI: 0.32-0.83; P=0.010) in obese group. HOMA-IR mediated the effect of BMI on CLBR by 27.5% ( P<0.05). Conclusions:High BMI before IVF/ICSI in PCOS patients negatively impacts CLBR and raises maternal and infant risks during pregnancy and the perinatal period. 27.5% of the effect of BMI on CLBR is mediated by HOMA-IR. Thus, PCOS patients should manage their BMI and enhance insulin sensitivity prior to pregnancy.

Objective:To investigate the impact of the progesterone concentration on human chorionic gonadotropin (hCG) trigger day in fresh cycles versus thawed transfer cycles (the freeze-all strategy) with an antagonist protocol, and to compare the differences in clinical outcomes.Methods:This retrospective cohort study included a total of 2 165 cycles conducted at Henan Provincial People′s Hospital with cleavage-stage embryo (at least one top-quality) transfer between January 2017 and December 2023, with serum progesterone levels on hCG trigger day all≤6.34 nmol/L (i.e. 2 ng/ml). Multivariate logsitic regression analysis and curve fitting were performed based on different serum progesterone levels on hCG trigger day [≤3.17 nmol/L (i.e. 1 ng/ml) or 1-2 ng/ml].Results:Multivariate regression analysis, by using cycle type (either fresh or frozen-thawed cycle) as the exposure variable, showed that the clinical pregnancy rate (≤1 ng/ml: OR=0.93, 95% CI: 0.75-1.14; 1-2 ng/ml: OR=1.05, 95% CI: 0.58-1.87) and live birth rate (≤1 ng/ml: OR=0.90, 95% CI: 0.71-1.13; 1-2 ng/ml: OR=1.53, 95% CI: 0.79-3.00) had no statistically significant differences in group of progesterone concentration ≤1 ng/ml or in group of 1-2 ng/ml. Using serum progesterone levels on hCG trigger day as a continuous variable for curve fitting analysis, the clinical pregnancy rate in fresh or thawed cycles showed no significant changes with increasing progesterone levels. Conclusions:In the antagonist protocol with cleavage-stage embryo transfer (at least one top-quality), when the serum progesterone level on hCG day is ≤2 ng/ml, there are no significant differences in clinical outcomes between thawed cycles and fresh cycles, including clinical pregnancy rate and live birth rate. Transferred in fresh cycles or choosing the freeze-all strategy could be selected based on the actual situation of the patients.

Objective:To analyze the clinical characteristics and genetic basis of a male patient with primary infertility caused by Acephalic spermatozoa syndrome.Methods:A patient who had presented at the Henan Provincial People′s Hospital on October 1, 2022 was selected as the study subject. Clinical data and results of laboratory exams and sperm electron microscopy were collected. The patient was subjected to whole exome sequencing (WES), and candidate variants were verified by Sanger sequencing and pathogenicity analysis.Results:WES revealed that the patient has harbored compound heterozygous variants of the PMFBP1 gene, namely c. 853del (p.Ala285Leufs*24) and c. 1276A>T (p.Lys426X), which were both unreported previously. Sanger sequencing suggested that the c. 853del (p.Ala285Leufs*24) variant has derived from his deceased mother, whilst the c. 1276A>T (p.Lys426X) variant has derived from his father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were classified as pathogenic (PVS1+ PM2_Supporting+ PP4). Conclusion:The compound heterozygous variants of the PMFBP1 gene probably underlay the Acephalic spermatozoa syndrome in this patient. The discovery of the novel variants has also enriched the mutational spectrum of Acephalic spermatozoa syndrome.
