Objective To analyze the correlation between glycolipid metabolism levels and diminished ovarian reserve (DOR) in perimenopausal women, and to explore the application value of menopausal hormone therapy.Methods A total of 194 perimenopausal women admitted to our hospital from February 2024 to February 2026 were retrospectively enrolled. They were divided into the DOR group (n=103) and the normal ovarian reserve (NOR) group (n=91) according to ovarian reserve function. Clinical data were compared between the two groups. Logistic regression analysis was used to identify risk factors for DOR. Receiver operating characteristic (ROC) curves were plotted to evaluate predictive efficacy, and Spearman correlation analysis was performed to assess indicator correlations. All patients received menopausal hormone therapy (MHT). Sex hormone indicators, glycolipid metabolic indicators, ultrasonographic indicators and safety indicators were compared before and after treatment.Results Multivariate Logistic regression showed that age, folliclestimulating hormone (FSH), glycated hemoglobin A1c (HbA1c) and triglyceride (TG) were independent risk factors for DOR in perimenopausal women (P＜0.05). ROC analysis revealed that the combined prediction yielded an AUC of 0.982 (95%CI: 0.964–1.000), with a sensitivity of 0.990 and a specificity of 0.923, and good calibration curve fitting. Ovarian reserve was significantly positively correlated with age, FSH, HbA1c and TG (all P＜0.05). After treatment, levels of FSH, luteinizing hormone (LH), HbA1c, TG and lowdensity lipoproteincholesterol (LDLC) decreased significantly (P＜0.05), and endometrial thickness increased slightly (P＜0.05). No significant changes were observed in antiMüllerian hormone (AMH) and ovarian volume (P＞0.05). The incidence of adverse reactions after MHT was 4.64%.Conclusion Abnormal glycolipid metabolism is closely associated with DOR and serves as a critical risk factor in perimenopausal women. Standardized MHT can effectively improve endocrinemetabolic disorders with satisfactory safety.

Objective To observe the characteristics of glucose, lipid and bone metabolism and bone mineral density (BMD)in postmenopausal women with type 2 diabetes mellitus (T2DM)in Shihezi district of Xinjiang province, and to investigate the relationship in the polymorphism and mutation of rs3736228 and rs3781586 of LRP5 gene and glucose,lipid and bone metabolism indexes in this population. Method A total of 136 postmenopausal Han women, who were related in the outpatient department, community, and hospital after hospitalization in Shihezi district of Xinjiang province from October 2016 to October 2017, were selected as the study subjects by the inclusion criteria and exclusion criteria.According to the patient's medicalhistory, glucosetolerance test results and bone mineral density (BMD), they were divided into 4 groups: normal glucose tolerance and normal bone mass (group A), normal glucose tolerance and abnormal bone mass (group B), type 2 diabetes and normal bone mass (group C), and type 2 diabetes mellitus and abnormal bone mass (group D). Baseline data such as patient's age, menopause years were measured and recorded, and body mass index (BMI)was calculated. Simultaneously, glucose metabolism indicators including fasting blood glucose (FBG, etc), bone metabolism indicators (blood Ca, etc), lipid metabolism indicators(triglycerides, etc)were detected. The polymorphisms of rs3736228 and rs3781586 of LRP5 gene were determined by Maldi-Tof-Ms and those data were analyzed statistically. Results ①Glucose metabolism index: compared with group A: FPG and HbAlc in group C, group D were all higher than group A (P<0.01). Lipid metabolism index: compared with group A, TG in group B and group D was lower than that in group A (P<0.05). Bone metabolism index: compared with group A, BMD (L1- 4)and BMD (femoral neck)in group B and group D were lower than those in group A (P<0.01). ②The distribution of SNP genotypes at rs3736228, rs3781586 of LRP5 conformsed to the Hardy-Weinberg genetic equilibrium law (P>0.05). The distribution frequency and allele frequency of LRP5 genotypes rs3736228, rs3781586 were compared among the groups. Pearson chi-square test showed no significant difference (P>0.05). ③Rs 3736228 locus of LRP5 gene:in group A, compared with CC (wild type), CT/TT (mutated type)triglyceride (TG)decreased (P<0.05), BMD (L1- 4)decreased (P<0.05). In group C, compared with CC (wild type), CT/TT (mutated type)high-density lipoprotein (HDL-C)increased (P<0.05), phosphorus increased (P<0.05). Rs 3781586 locus of LRP5 gene: in group B, compared with GG (wild type), GT/TT (mutated type)high-density lipoprotein (HDL-C)increased (P<0.05).Conclusion In the Xinjiang Shihezi district among postmenopausal women with type 2 diabetes, rs3736228, rs3781586 loci of LRP5 gene polymorphism may be irrelevant to glucose metabolism, but the mutation of rs3736228 of LRP5 gene locus may be related to lipid metabolism and bone metabolism (TG, HDL-C, BMD, P), and the mutation of rs3781586 may be related to lipid metabolism (HDL-C).

目的 探究Harris-Benedict(HB)公式用于估算机械通气的危重症患者能量代谢的准确性,以及不同BMI分组对其影响。方法 使用间接能量测定法测量患者的静息能量(ICREE),通过HB公式计算其静息能量代谢估算值(HBREE)。将80例患者按BMI分为4组,并通过配对样本t检验对ICREE与HBREE进行比较,Pearson分析用于分析ICREE与HBREE的相关性。结果 共纳入80例机械通气的危重症患者。除肥胖组外的其余各组病人,ICREE均高于HBREE(均P＜0.01),HB公式的准确率为23.75%。ICREE与HBREE相关性差(r=0.331,P＜0.01)。当各组使用校正系数对HB公式进行调整后,ICREE与HBREE差异无统计学意义,准确率提高至38.8%。结论 使用HB公式不能很好地反应危重症患者的实际能量代谢。BMI可能是影响HB公式准确性的重要因素。依据不同BMI分组,使用相应校正系数可提高HB公式的准确性。

Objective To explore the accuracy of the Harris-Benedict (HB) formula used to estimate the energy metabolism in critically ill patients undergoing mechanical ventilation and the effects of different BMI groups on it. Methods Indirect calorimetry was used to measure the resting energy of the patient,and the estimated resting energy metabolism was calculated by the HB formula. 80 patients were divided into four groups according to BMI. ICREE and HBREE were compared by paired sample t test. Pearson analysis was used to analyze the correlation between ICREE and HBREE. Results This study included 80 critically ill patients undergoing mechanical ventilation.Except for the obese group,ICREEE was higher than HBREE in all patients and the remaining groups of patients. The accuracy rate of the HB formula was 23.75%. The correlation between ICREE and HBREE is poor(r=0.331,P＜0.01). There was no statistical difference between ICREEE and HBREE and the accuracy rate increased to 38.8% after the Harris-Benedict equation was adjusted by using the correction factor. Conclusion Using the HB formula can not reflect the actual energy metabolism of critically ill patients well. BMI may be an important factor affecting the accuracy of HB formula. The accuracy of the HB equation can be improved by using different correction factors according to different BMI groupings.

Objective To explore the effect of liraglutide and metformin on bone metabolism in newly diagnosed type 2 diabetic patients. Methods From January 2016 to June 2017, 50 patients with type 2 diabetes mellitus admitted to our hospital were selected. According to the random number table method, the subjects were randomly divided into liraglutide group and metformin group, 25 in each group. Changes in bone mineral density and bone metabolism were compared between the two groups after 24 weeks of monotherapy. Results That there was no significant change in bone mineral density, serum ALP, TPINP,and BGP levels before and after treatment (P>0.05). The β-CTx levels in patients in the liraglutide group were lower than that before treatment (P<0.05); FPG, 2hFPG, HOMA-IR, and HbA1c levels in the two groups were lower than that before treatment (P<0.05). Fasting insulin was higher than that before treatment (P<0.05); BMI was lower in the liraglutide group after 24 weeks of treatment than that before treatment (P<0.05). Conclusion The effects of liraglutide and metformin on the bone mineral density of patients with newly diagnosed type 2 diabetes are not obvious. Liraglutide may reduce serum β-CTx levels during use. We need to have further study whether it has a bone protection.
