Objective:To investigate the effect of endometriosis (EMT) on oocytes, embryo quality and pregnancy and delivery outcomes in infertility patients treated with in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). Methods:A retrospective cohort study was conducted to select the EMT patients (383 cases, EMT group) and the infertility patients with tubal factor (1 613 cases, control group) who underwent IVF/ICSI-ET treatment in the Department of Reproductive Medicine, the First Affiliated Hospital of Harbin Medical University from January 2016 to December 2023. The cases were matched with the number of age, body mass index, anti-Müllerian hormone, proportion of infertility type, duration of infertility, ovulation stimulating therapy, insemination mode, number of previous IVF/ICSI cycles of the two groups by 1∶1 propensity score matching. Totally 285 patients with EMT and 285 patients in control group were finally included to analyze the effects of EMT on embryo quality and pregnancy outcome.Results:1) There were no statistically significant differences in the duration of gonadotropin (Gn) used, the total dosage and the initiating dosage of Gn used, and the levels of estradiol, luteinizing hormone, and progesterone on the human chorionic gonadotropin (hCG) injection day between the two groups (all P>0.05). 2) The total number of oocytes (7.48±5.15), the number of MⅡ oocytes (6.38±4.61), the number of transferable embryos (4.16±3.16), the number of high-quality embryos [2.00 (0.00, 3.00)] and the rate of two pronuclei (2PN) high-quality embryos [42.33% (602/1 422)] in EMT group were all lower than those in control group [8.45±4.86, P=0.021; 7.32±4.43, P=0.013; 4.95±3.19, P=0.003; 2.00 (1.00, 4.00), P=0.002; 48.76% (747/1 532), P=0.032], the differences were statistically significant. 3) There were no statistically significant differences in clinical pregnancy rate, embryo implantation rate, premature birth rate, early abortion rate, ectopic pregnancy rate, male/female ratio, number of weeks of delivery and cesarean section rate between the two groups with fresh cycle transplantation and with embryo freezing in fresh cycle and embryo transferred in the first resuscitation cycle (all P>0.05), the live birth rate of EMT patients with fresh cycle transplantation [29.71% (41/138)] was lower than that of control group [48.90% (89/182), P=0.023], and the difference was statistically significant. 4) EMT was not an independent factor of clinical pregnancy rate and live birth rate after IVF/ICSI treatment, but age and number of embryos transferred were independent factors of clinical pregnancy rate and live birth rate of IVF/ICSI treatment ( OR=0.923, 95% CI: 0.868-0.982, P=0.011; OR=0.890, 95% CI: 0.832-0.952, P=0.001; OR=2.408, 95% CI: 1.331-4.356, P=0.004; OR=3.838, 95% CI: 1.869-7.879, P<0.001). Conclusion:EMT may reduce the number of oocytes and MⅡ oocytes in infertility patients treated with IVF/ICSI-ET, and the quality of embryos in patients with EMT treated with IVF is worse, but it does not affect the clinical pregnancy outcome and delivery outcome in patients with EMT.

Objective:To analyze the prevalence and disease burden of male and female infertility in China from 1990 to 2019.Methods:The global disease burden database of 2019 was used to analyze the prevalence of male and female infertility and disability adjusted life years (DALY) in China from 1990 to 2019 among the total Chinese male and female population and different age groups.Results:In 2019, the number, prevalence, DALY and DALY rate of male infertility in China were 14 577 432, 2 011.18/100 000, 77 983 person years, 1 076/100 000, respectively. The number, prevalence, DALY and DALY rate of female infertility were 37 884 300, 5 431.22/100 000, 197 046 person years, 28.25/100 000, respectively. The prevalence and disease burden of female infertility were higher than those of male infertility. The age group with the highest male prevalence rate and DALY rate were 35-39 and 30-34 years old respectively, the age group with the highest female prevalence rate and DALY rate were 40-44 and 35-39 years old respectively, and the age group with the highest female prevalence rate and DALY rate was 5 years later than the male age group. From 1990 to 2019, the prevalence rate and DALY rate of male and female infertility increased in the first 20 years or so, and decreased in the last 10 years or so. The prevalence rate and DALY rate of male and female infertility in China were significantly higher than those in the whole world and different socio-demographic index (SDI) regions.Conclusion:Although the prevalence rate and DALY rate of male and female infertility in China have decreased in recent years, the population base of China is large, and the disease burden of male and female infertility in the world is still large. Active prevention and treatment measures should be taken to reduce the disease burden of male and female infertility.

[ ABSTRACT] AIM:To investigate the effect of insulin resistance ( IR) on the biological function of hepatocellu-lar carcinoma ( HCC) and sensitivity to cisplatin.METHODS:IR was induced in HepG2 cells via incubation with a high concentration of insulin.Afterwards, the effects of IR on adhesion, migration, invasion and sensitivity to cisplatin of the cells were detected.RESULTS:The results indicated that glucose consumption was reduced in the IR cells.The expres-sion of the insulin receptor and glucose transporter 2 was down-regulated.Furthermore, HepG2/IR cells displayed marked-ly enhanced adhesion, migration, and invasion.These cells exhibited a lower sensitivity to cisplatin.On the contrary, HepG2/IR cells exhibited decreased adhesion and invasion after treatment with the insulin sensitizer pioglitazone hydrochlo-ride.CONCLUSION:IR is closely related to drug resistance, adhesion, migration and invasion in HepG2 cells.These findings may help explain the clinical observation of the limited efficacy of chemotherapy on a background of IR.

Objective To observe the effect of integrated therapy of Chinese medicine and chemical drugs on adverse reaction and curative effect of initial treatment of secondary pulmonary tuberculosis. Methods Totally 1404 patients with secondary pulmonary tuberculosis and TCM lung consumption diagnostic criteria (syndrome of lung yin deficiency, qi-yin deficiency, yin-deficiency caused excessive fire) were chosen for single blind, randomized, controlled, multicenter clinical trials. Trial group was given 2HRZE/4HR, 1 time/day with Chinese medicine 2 or 3 times/day, and control group was given 2HRZE/4HR only for six months. The adverse reactions and clinical symptoms were observed to evaluate clinical efficacy and safety. Results In terms of reducing liver damage and other adverse reactions, the ratio of trial group had statistical difference with that of control group (P<0.001). In symptom scores of lung yin deficiency syndrome treated for 2, 4, 6 months, yin-deficiency caused excessive fire syndrome treated for 6 months, qi-yin deficiency syndrome treated for 4, 6 months, the differences between the two groups were significant (P<0.001). TCM syndrome curative effect between the two groups was statistical different (P<0.001). Safety evaluation result between the two groups was statistical different by tratified analysis (P<0.001). Conclusion Integrated therapy of Chinese medicine and chemical drugs can improve the symptoms and reduce adverse reactions caused by chemical drugs. It can enhance the curative effect and safety.
