This paper comprehensively discusses the impact of obesity on female fertility, oocyte quality, early embryonic development, and assisted reproductive technology (ART), and evaluates the relationship between obesity and pregnancy complications, proposing corresponding prevention and treatment strategies. Studies have shown that obesity adversely affects oocyte quality through chronic inflammation, oxidative stress, and disruption of metabolic pathways, including meiotic defects, mitochondrial dysfunction, and epigenetic alterations. Obesity also affects early embryonic development, potentially leading to placental dysfunction and restricted fetal growth. In the field of ART, obese women face more challenges, such as increased risk of gestational diabetes and decreased success rates of in vitro fertilization. Additionally, obesity is associated with an increased risk of various pregnancy complications, including hypertensive disorders of pregnancy, gestational diabetes, preterm birth, and cesarean section. This paper emphasizes the importance of preconception and prenatal weight management and proposes strategies to improve the fertility of obese women through lifestyle changes, pharmacological treatment, and surgical intervention. Ultimately, this thesis provides personalized recommendations for the reproductive health of obese women to improve fertility and pregnancy outcomes, ensuring the health status of both mother and child.

Objective To explore the expressions and significance of Galectin‐3 and Bcl‐2 in colorectal tissues of patients with ulcerative colitis(UC) .Methods Immunohistochemical SP method was applied to detected the expression of Galectin‐3 and Bcl‐2 in colorectal tissues of 60 patients in UC group and 20 healthy adults in the control group ,and analyzed the relationship of the expres‐sions between Galectin‐3 and Bcl‐2 .It was regarded as positive cell when obvious dark brown granules appeared in cytoplasm or cyteblast .Semi‐quantitative analysis was used basing on the staining intensity and the amount of the staining intensity and positive cells .Results Galectin‐3 and Bcl‐2 proteins expressed in cytoplasm .Galectin‐3 showed strong expression in normal colorectal epi‐thelium but weak in UC inflammatory tissues ,and it was associated with different lesion degrees under endoscopy .The expressions of Bcl‐2 were weak in normal colorectal epithelium ,and it enhanced significantly in UC inflammatory tissues ,especially in inflamma‐tory cells of laminae propria ,and it was not associated with different lesion degrees under endoscopy .The expression of Galectin‐3 and Bcl‐2 was not associated with the age ,sex of patients and the course of UC .Pearson correlation analysis showed that the posi‐tive expressions of Galectin‐3 and Bcl‐2 had no relevance .Conclusion Galectin‐3 and Bcl‐2 involved in the pathogenesis of UC . They may be able to used as markers of early diagnosis and prognosis in UC and may play the role in the pathogenesis of UC inde‐pendently .

Objective To analyze the clinical characteristics and relevant factors of 88 cases of cirrhotic portal hyper-tension complicated with gallstone. Methods A total of 366 patients with cirrhotic portal hypertension complicated with gallstone were selected. 88 patients were assigned to a gallstone group and 278 patients were assigned to a control group on the basis of clinical diagnosis. Retrospective analysis was carried out for clinical data and auxiliary examina-tion data of the two groups, and single-factor and multi-factor analyses were applied for the risk factors of cirrhotic portal hypertension complicated with gallstone. Results Child-Pugh grade ≥B, ascites, peak systolic flow velocity of hepatic artery, portal thrombosis, peripancreatic varicose veins, and varicose veins of gallbladder were independent risk factors of cirrhotic portal hypertension complicated with gallstone (P<0.05). Conclusion Cirrhotic portal hypertension complicated with gallstone is related to hepatic functions, ascites, hemodynamics of hepatic artery, and collateral circu-lation of portal vein, and Child-Pugh grade≥B, ascites, peak systolic flow velocity of hepatic artery, portal thrombosis, peripancreatic varicose veins, and varicose veins of gallbladder are independent risk factors.

ObjectiveTo observe the effects of human IL-10 gene transfection on the mRNA and protein expressions of IL-1β and TNF-α in the penumbra area following focal cerebral ischemia-reperfusion injury in rats and to investigate its neuroprotective mechanism. MethodsRats were divided into four groups: normal control group, ischemic control group, empty plasmid group and human IL-10 gene transfected group. The mRNA and protein expressions of IL-1β and TNF-α in the penumbra area were detected by fluorescence real-time quantitative PCR and ELISA respectively. ResultsIn normal control group, ischemic control group, empty plasmid group and human IL-10 gene transfected group, the levels of protein expression of TNF-α in penumbra area were(0.66±0. 04) ,(1.16±0.26),(1. 155±0. 26)ng/g and(0. 84±0. 05)ng/g, and the levels of protein expression of IL-1βin penumbra area were(0.37±0.05), (1.25±0.39), (1.21±0.57) ng/g and(0.62+0.05)ng/g, respectively. Compared with normal control group, the levels of protein expression of TNF-α and 1L-1β were significantly higher in other three groups(all P＜0. 01), and lower in human IL-10 gene transfected group than in ischemic control group and empty plasmid group(all P＜0. 01). In normal control group, ischemic control group, empty plasmid group and human IL-10 gene transfectedgroup, the levels of mRNA expression of TNF-α in penumbra area were 1.00 ±0.53,9.42±1.83,9.69±1.96 and 3.53±1.09, and the levels of mRNA expression of IL-1β in penumbra area were 1.00 ±0.51,27. 81±4.84,23.96 ± 4.90 and 13.55± 4.45, respectively. Compared with normal control group, the levels of mRNA expression of TNF-α and IL-1β were significantly higher in other three groups(all P＜0. 01), and lower in human IL-10 gene transfected group than in ischemic control group and empty plasmid group(all P＜0. 01). ConclusionsThe human IL-10 gene transfection may play an protective effect on cerebral ischemia through inhibiting mRNA and protein expression of IL-1β and TNF-α in the penumbra area following focal cerebral ischemia-reperfusion in rats.
