Objective To exploring the effect of inflammatory indicators on the outcome of assisted conception of in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)in patients with ovarian endometriosis(OEM).Methods The study subjects were selected as the patients with OEM who received IVF/ICSI treatment at the Third Affiliated Hospital of Zhengzhou University from January 2019 to February 2024.Based on whether previous surgery for uterine endometriosis cyst removal had been performed,they were divided into non-surgery group(n=73)and surgery group(n=112).To explore the differences in inflammatory markers between two groups and to determine whether they have an impact on the outcome of assisted reproduction.Results The lymphocytes(L)and blastocyst formation rates of patients in surgery group were significantly higher than those in non-surgery group,platelet to lymphocyte ratio(PLR)and carbohydrate antigen 125(CA125)were significantly lower than those in non-surgery group(P＜0.05).There were no statistically significant differences in the clinical pregnancy rate and live birth rate between two groups of patients(P＞0.05).After adjusting for confounding factors,the results of multivariate Logistic regression analysis showed that L,PLR,and CA125 had no statistically significant impact on the clinical pregnancy rate and live birth rate(P＞0.05).Both maternal age and the number of embryos transferred exerted a certain influence on clinical pregnancy rates and live birth rates(P＜0.05),furthermore,the type of embryo transferred had a significant effect on clinical pregnancy rates(P＜0.05).Conclusion Compared with non-surgery group,surgery group had higher L level and lower PRL and CA125 levels,but these changes did not significantly affect clinical pregnancy or live birth outcomes in OEM patients undergoing IVF/ICSI assisted reproduction.

Objective:To explore the deubiquitination modification of the deubiquitinase BRCC3 in rats with neuropathic pain (NPP) treated with meridian tuina of Zhuang medicine and its analgesic molecular mechanism.Methods:Rats were divided into normal group, sham-operation group, model group, sham-tuina group, and meridian tuina of Zhuang medicine group using a random number table method, with 9 rats in each group. Except for the normal and sham operation groups, spinal nerve ligation models were prepared in all other groups. On the first day after surgery, intervention was carried out on the meridian tuina of Zhuang medicine and sham-tuina groups for 14 days, while the other three groups were not intervened; the paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) of each group of rats were measured at 0 days before operation, 1, 7, and 14 days after operation. Western blot was used to detect the expressions of BRCC3 and NLRP3 proteins in spinal cord tissue, and ELISA was used to detect the level of IL-1β in serum.Results:On postoperative 7 and 14 d, compared with the model group, the meridian tuina of Zhuang medicine group showed an increase in PWMT and PWTL, a decrease in NLPR3 and BRCC3 expression in spinal cord tissue, and a decrease in serum IL-1β levels ( P<0.05). Compared with the sham-tuina group, the meridian tuina of Zhuang medicine group showed an increase in PWMT and PWTL, a decrease in NLRP3 protein expression in spinal cord tissue, and a decrease in IL-1β levels in serum ( P<0.05). Conclusion:Meridian tuina of Zhuang medicine can alleviate pain sensitivity in SNL model rats, and its mechanism is related to the inhibition of the expression of deubiquitinase BRCC3 by meridian massage of Zhuang medicine, which increases the ubiquitination level of NLRP3 and hinders its activation, thereby blocking the immune inflammatory response mediated by inflammatory factors.

Objective:To investigate whether malignant tumors affect the laboratory outcomes of patients in their first controlled ovarian hyperstimulation (COH) cycle.Methods:This study was a retrospective case-control study that analyzed the clinical and laboratory data of patients who underwent fertility preservation before chemotherapy and radiotherapy due to malignant tumors, as well as patients with infertility caused by tubal factors who first underwent in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) at the Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2020 to May 2024. Patients who underwent fertility preservation were designated as the research group, while patients who underwent assisted reproduction due to tubal factors during the same period were designated as control group. After 1∶3 propensity score matching (PSM), 40 patients were included in the research group and 118 patients were included in control group. The ovarian response, oocyte retrieval outcomes, and embryonic development after fertilization in the first COH cycle were compared between the two groups. Results:After PSM, the research group and control group showed statistically significant differences in the gonadotropin (Gn) starting dosage [225.00 (162.50, 300.00) U vs. 193.75 (150.00, 225.00) U, P=0.002], duration of Gn used [10.00 (8.00, 11.00) d vs. 12.00 (10.00, 13.00) d, P<0.001], and average estradiol levels on human chorionic gonadotropin trigger day [2 487.00 (1 461.25, 4 090.25) pmol/L vs. 10 738.50 (8 400.00, 16 507.25) pmol/L, P<0.001]. However, no statistically significant difference was found in the total dosages of Gn used between the two groups ( P>0.05). There were no significant differences between the groups in terms of the number of oocytes retrieved, the number of metaphase Ⅱ oocytes, two pronuclei (2PN) rate, 2PN cleavage rate, available embryo rate, high-quality embryo rate, blastocyst formation rate, and available blastocyst formation rate (all P>0.05). Conclusion:Compared with infertility patients with tubal factors, there is no significant difference in the laboratory outcomes of malignant tumor patients undergoing COH for fertility preservation prior to chemotherapy and radiation.

Objective:To investigate the pregnancy outcomes in patients ≤35 years old with diminished ovarian reserve (DOR) undergoing intrauterine insemination (IUI).Methods:A retrospective cohort study was conducted by analyzing the clinical data of 6 229 IUI cycles performed in patients aged ≤35 years at the Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University between June 2016 and March 2024. Based on serum anti-Müllerian hormone (AMH) levels, the subjects were divided into two groups: patients with AMH <1.1 μg/L were classified as the DOR group (489 cycles), and patients with AMH ≥1.1 μg/L were classified as the normal ovarian reserve (NOR) group (5 740 cycles). Propensity score matching (PSM) was applied to control for confounding factors, after 1∶1 PSM matching, 486 cycles were included in each group. Clinical pregnancy rate, miscarriage rate, live birth rate, biochemical pregnancy rate, and ectopic pregnancy rate were compared between the two groups by generalized estimating equations.Results:The clinical pregnancy rate was 21.19% (103/486) in DOR group and 24.07% (117/486) in NOR group, with no statistically significant difference ( P=0.294). The live birth rate was 18.31% (89/486) in DOR group and 20.16% (98/486) in NOR group, also without significant difference ( P=0.469). Additionally, no significant differences were observed in miscarriage rate, biochemical pregnancy rate, or ectopic pregnancy rate between the two groups (all P>0.05). Conclusion:In patients aged ≤35 years with DOR, pregnancy outcomes from IUI are comparable to those in young patients with NOR.

The methodological investigation was qualified， and the contents of corydaline and tetrahydropalmatine in 10 batches of Yuanhu Zhitong oral liquid samples were 0.077 5-0.142 9、0.126 1-0.178 2 g·L^-1， respectively. ConclusionThe established TLC， fingerprint and determination are simple， specific and reproducible， which can be used to improve the quality control standard of Yuanhu Zhitong oral liquid.

Objective:To explore the impact on the fertility and outcomes of females with squamous intraepithelial lesion (SIL) undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) and obstetric outcomes after local treatment. Methods:Patients with SIL undergoing IVF/ICSI were set as the SIL group in the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from January 2016 to December 2020. While, control group was matched using the propensity scoring method in a 1∶3 ratio in accordance with the age, body mass index, and basic follicle-stimulating hormone, antral follicle count and the oocytes retrieval time. Pregnancy outcomes were compared by analyzing the basic conditions of the two groups, the index of the IVF/ICSI cycles, the clinical pregnancy rate and the implantation rate of the fresh cycles, the cumulative pregnancy rate, the cumulative live birth rate, and obstetric outcomes of patients giving live birth after local treatment were also analyzed.Results:The demographic characteristics were of no significant differences between the SIL group and control group (all P>0.05). As for the IVF/ICSI results, no significant differences were observed in the duration of gonadotropins (Gn) used, total dosage of Gn used, No. of oocytes retrieved, normal fertilization rate, No. of available embryos, No. of high-quality embryos, and No. of blastocyst formation between the two groups (all P>0.05). For fresh embryo transfer cycles, the number of transferred embryos was lower, the clinical pregnancy rate and the implantation rate in the SIL group were higher than those in control group, while the differences were not significant (all P>0.05). The differences of time to pregnancy,the cumulative pregnancy rate and the cumulative live birth rate between SIL group and control group were not statistically significant (all P>0.05). There were no statistically significant differences in delivery methods, gestational age, newborn birth weight, and incidence of pregnancy complications between the two groups (all P>0.05). According to local surgical treatment, 79 patients with SIL who achieved live birth were divided into cold knife conization subgroup, loop electrosurgical excisional procedure subgroup, and no-operation subgroup. There were no statistically significant differences in delivery methods, gestational age, newborn birth weight and incidence of pregnancy complications among the three subgroups (all P>0.05). Conclusion:SIL did not affect fertility of patients or assisted pregnancy outcomes of IVF/ICSI, and local surgical treatment does not increase the risk of preterm birth, low birth weight infants.
