Objective To observe the effect of ulinastatin on the expression of interleukin 15 (IL-15), connective tissue growth factor (CTGF) and malondialdehyde (MDA) in rat peritoneal mesothelial cells (RPMCs) induced by high glucose. Methods RPMCs were isolated, cultured and passaged by trypsin, then identified. The third generation of cultured RPMCs were used in the experiment. RPMCs were divided into normal control group, high glucose (1.5%, 2.5%, 4.25%) for 6 hours and 12 hours, high glucose (2.5%) for 3, 6, 12, 24 hours or ulinastatin (160, 320, 640U/ml) for 12 hours. IL-15 mRNA was detected by real-time PCR. IL-15 and CTGF protein in supernatants was detected by ELISA. MDA protein was detected by TBAS. Results Compared with the control group, the expression of IL-15, CTGF and MDA was significantly increased in the groups stimulated by high glucose (P<0.05) in dose- and time-dependent manner. Ulinastatin could significantly decrease the expression of IL-15, CTGF and MDA induced by high glucose in dosedependent manner both in protein and gene levels (P<0.05). Conclusions High glucose can up-regulate the expression of IL-15, CTGF and MDA in RPMCs. Ulinastatin can reverse these changes.

Objective:To investigate the effect of body mass index (BMI) on clinical pregnancy and neonatal outcomes in patients with polycystic ovary syndrome (PCOS) during frozen-thawed embryo transfer.Methods:A total of 650 patients with PCOS who received routine in vitro fertilization or intracytoplasmic sperm injection treatment for frozen-thawed embryo transfer from June 2014 to June 2019 in Tianjin Central Hospital of Gynecology Obstetrics were retrospectively analyzed. According to BMI, PCOS patients were divided into group A (18.5≤BMI<23 kg/m 2, n=253), group B (23≤BMI<25 kg/m 2, n=167), and group C (BMI≥25 kg/m 2, n=230). The general information, clinical pregnancy outcomes, pregnancy complications, the incidence of macrosomia and low-birth-weight infants were compared in the three groups, and the influencing factors of neonatal birth weight were analyzed. Results:The embryo implantation rate, clinical pregnancy rate, and ongoing pregnancy rate all showed downward trend with the increase of BMI, but the differences were not statistically significant (all P>0.05). The live birth rate in group C [47.0% (108/230)] was significantly lower than those in groups A and B, with statistical significance ( χ2 =7.43, P=0.024). The late miscarriage rate was higher in group C [9.4% (13/139)] than in groups A and B ( χ2 =7.66, P=0.022). The birth rates of macrosomia in groups B [22.2% (16/72)] and group C [21.1% (16/76)] were significantly higher than that in group A, and the difference was statistically significant ( χ2 =14.15, P=0.001). There was no statistically significant difference in the incidence of gestational diabetes between the three groups ( χ2 =3.81, P=0.149). The incidence of hypertension disorders complicating pregnancy increased with the increase of BMI, and the difference was not statistically significant ( P>0.05). Regression analysis showed that macrosomia was significantly associated with maternal pre-pregnancy BMI and gestational weeks, and the risk of macrosomia increased by 15% (95% CI: 3%-28%) for every increase in maternal BMI. Conclusions:The embryo implantation rate, clinical pregnancy rate, and ongoing pregnancy rate of PCOS patients in frozen-thawed embryo transfer cycles show downward trend with the increase of BMI. Obese patients with PCOS have a significant increase in late miscarriage rate and a significant decrease in live birth rate. The incidence of hypertension disorders complicating pregnancy in PCOS patients in the obese group has an increasing trend, and the birth rate of macrosomia has increased significantly. Therefore, it is recommended that obese women with PCOS lose weight scientifically before pregnancy to improve pregnancy and neonatal outcomes.

OBJECTIVE:
To assess the value of preimplantation genetic test (PGT) based on next generation sequencing (NGS) for achieving pregnancy for 71 couples with one partner carrying a reciprocal or Robertsonian translocation.
METHODS:
Following blastocyst biopsy, whole genome of single cell was amplified, and PGT was performed by NGS. The subjects included 60 couples with one partner carrying a reciprocal translocation and 11 with one partner carrying a Robertsonian translocation. The results of PGT, implantation and prenatal diagnosis for all of the couples were analyzed.
RESULTS:
In total 301 embryos were obtained for the 71 couples through 92 ovulation cycles, 287 (95.3%) of which were successfully diagnosed by NGS. Eighty-five euploidy embryos were identified for the reciprocal translocation carrier group. In 18 cycles, no euploid embryo was obtained. Cancellation rate for the cycles was 19.5%. For reciprocal translocation carrier group and Robertsonian translocation carrier group, the rates for implantation, early abortion, and clinical pregnancy were 89.3% (42/47), 25.5% (12/47), 63.8% (30/47), and 88.8% (8/9), 22.2% (2/9), and 66.6% (6/9), respectively. The result of prenatal diagnosis was consistent with the that of PGT.
CONCLUSION
PGT based on NGS can effectively identify euploid embryos and reduce recurrent abortions and termination of pregnancies, achieving a satisfactory rate for clinical pregnancy.

Objective:
To assess the value of next-generation sequencing (NGS)-based single nucleotide polymorphism (SNP) haplotyping for preimplantation genetic diagnosis (PGD) for beta-thalassemia coupled with human leukocyte antigen (HLA) matching.
Methods:
Three couples were recruited. Couple 1 both carried a βIVS-2-654 variation and had previously given birth to a son with β thalassemia major. Couple 2 respectively carried βcd41-42 and βIVS-2-654 but had no history of pregnancy. Couple 3 respectively carried βCD17and βIVS-2-654, and had a daughter carrying βCD17.
Results:
For couple 1, NGS-SNP typing identified two embryos not only unaffected with thalassemia but also with matched HLA. One blastocyst was transferred and resulted in successful pregnancy. A healthy baby was born at 39th week of gestation. Its umbilical blood was used to treat the sick brother through hemopoietic stem cell transplantation. For couple 2, seven blastocysts were obtained. Second transplantation has resulted in successful pregnancy. Prenatal diagnosis was consistent with PGD. For couple 3, two blastocysts not only unaffected with thalassemia but also with no pathogenic copy number variations were obtained. Transfer of one blastocyte resulted in successful pregnancy, and prenatal diagnosis was consistent with PGD.
Conclusion
NGS-based SNP typing is an useful tool for selecting embryos unaffected with beta-thalassemia and matched HLA through PGD.

Objective:To understand the occurrence of major adverse cardiac events (MACE) during the perioperative period of cervical spine surgery and analyze its risk factors.Methods:A retrospective analysis of 426 cervical spine surgery patients admitted to the from March 2017 to March 2021. The basic information of the patients, including gender, age, body mass index (BMI), underlying diseases, and the Charlson comorbidity index (CCI) was calculated based on the underlying diseases.The preoperative serum cardiac troponin I(cTnI) level and the operation-related indicators were collected,including the type of cervical spine surgery, surgical procedure, approach, duration of surgery, duration of anesthesia, intraoperative bleeding, postoperative pain visual analogue scale (VAS), and electrolyte disturbances. Count data were expressed as cases (%), and comparisons between groups were made using the χ 2 test; logistic regression models were applied to perform a multifactorial analysis of the factors influencing the perioperative occurrence of MACE in patients undergoing cervical spine surgery. Results:Among the 426 patients, 54 (12.68%) experienced MACE during the perioperative period, including 4 cases of unstable angina (7.41%), 4 cases of acute myocardial infarction (7.41%), 33 cases of severe arrhythmia (61.11%), and 13 cases of acute heart failure (24.07%). The results of multivariate logistic regression analysis showed that the older the age group (50-59 years old: odds ratio=1.34, 95% confidence interval: 1.14-1.78; 60-69 years old: odds ratio=1.48, 95% confidence interval: 1.20-1.86; 70-79 years old: odds ratio=1.71, 95% confidence interval: 1.34-2.57; 80-89 years old: odds ratio=1.95, 95% confidence interval: 1.46-2.85), as well as females, CCI scores>3, and preoperative cTnI>0.04 μg/L, postoperative VAS score>5, and electrolyte disorders are all influencing factors for the occurrence of MACE in cervical spine surgery patients during the perioperative period (odds ratios of 1.84, 2.12, 2.34, 2.57, 2.20, 95% confidence intervals of 1.34-2.68, 1.50-3.41, 1.63-3.72, 1.53-4.01, 1.43-3.69, all P<0.05). Conclusions:The incidence of MACE in the perioperative period of cervical spine surgery is relatively high. Elderly age, female, high CCI score, high preoperative serum cTnI, postoperative pain and electrolyte disturbance are independent risk factors for the perioperative period of cervical spine surgery.
