Objective To investigate the correlation between serum nickel-like protein(Metrnl)level and glycolipid metabolism and inflammatory state in patients with T2DM complicated with abdominal obesity.Methods One hundred and twenty-four T2DM patients and 140 non-diabetic controls who were hospitalized in Gansu Provincial People's Hospital from May to September 2022 were selected and divided into T2DM combined abdominal obesity group(T2DM+AO,n=81),T2DM group(n=43),abdominal obesity group(AO,n=69)and normal control group(NC,n=71)according to whether they suffered from T2DM and abdominal obesity.ELISA method was used to determine the levels of serum Metrnl,IL-4 and IL-13.The correlation between serum Metrnl and the indicators of glucose and lipid metabolism,WC,BMI,VFA,FPG,HbA1c,TC,TG,LDL-C,HDL-C and the indicators of inflammatory state,IL-4 and IL-13 were analyzed.Results Compared with NC group,serum Metrnl levels in T2DM group,AO and T2DM+AO group were decreased(P＜0.05).Serum Metrnl was negatively correlated with WC,BMI,VFA,FPG,HbA1c,TG,IL-4,IL-13(P＜0.01),and positively correlated with HDL-C(P＜0.05).Age,WC,BMI and IL-4 were the influencing factors of Metrnl.WC,VFA,FPG and Metrnl were the influencing factors of T2DM combined with abdominal obesity.The ROC curve showed that serum Metrnl had a sensitivity of 82.5%and a specificity of 93.8%for the diagnosis of T2DM with abdominal obesity.Conclusions Serum Metrnl in T2DM patients with abdominal obesity is significantly reduced,and is closely related to glucose and lipid metabolism and inflammatory status.Serum Metrnl may be a novel biomarker factor for T2DM complicated with abdominal obesity.

Objective:To investigate urinary pH distribution and its influencing factors in gout patients, to provide insights for individualized treatment.Methods:This is a retrospective study. The gout patients in the Gout Outpatient Department of the Affiliated Hospital of Qingdao University from September 2019 to August 2021 were collected. Clinical data were collected and relevant indicators were measured. The patients were divided into different groups according to urinary pH. Clinical characteristics and factors related to urinary pH were compared among the groups. SPSS 23.0 software was used.Results:A total of 2 553 patients were enrolled. There were significant statistical differences in age, body mass index, triglyceride, alanine aminotransferase(ALT), blood urea nitrogen, serum creatinine, estimated glomerular filtration rate(eGFR), blood uric acid, urinary uric acid/creatinine ratio, fraction excretion of uric acid(FEUA) among groups with different urinary pH( F were 5.114, 4.772, 7.170, 4.721, 13.603, 2.812, 3.422, 22.834, 18.230, 26.332, all P<0.05). Urinary uric acid and FEUA in acute group were higher than those in remission group( Z were -2.295, -3.528, both P<0.05). After adjusting for gender, age, eGFR, logistics regression analysis showed that body mass index, triglyceride, total cholesterol, ALT, blood uric acid, and blood urea nitrogen were still risk factors. Multivariate logistic regression analysis showed that triglyceride, blood uric acid, and blood urea nitrogen were independent risk factors associated with acid urine. Linear correlation analysis showed that urinary pH was negatively correlated with body mass index, triglyceride, total cholesterol, blood uric acid, fasting glucose, blood urea nitrogen, ALT( r were -0.079, -0.106, -0.051, -0.186, -0.040, -0.122, -0.051, all P<0.05), but positively correlated with eGFR( r=0.058, P=0.003). Conclusion:The overall urine pH levels in patients with primary gout are below normal reference. Several metabolic components are related to it. Triglyceride, blood uric acid, and blood urea nitrogen are independent risk factors of acidic urine. In clinical practice, attention should be paid to timely alkalization of urine to prevent complications.

Aim To study the effect of liraglutide on myocardial metabolites and related metabolic pathways in diabetic cardiomyopathy(DCM)rats.Methods Among 60 SPF male SD rats aged 3 weeks,10 rats were randomly selected as normal control group(n=10),and the remaining 50 rats were established by peritoneal injection of streptozoto-cin combined with high-sugar and high-fat diet for DCM rat model.A total of 36 rats were successfully modeled for DCM and randomly divided into DCM model group(DCM group,n=12),low-dose liraglutide treatment group(LL group,n=12)and high-dose liraglutide treatment group(HL group,n=12).Rats in LL group(100 μg/kg)and HL group(200μg/kg)were given intraperitoneal injection of liraglutide once a day.And after 12 weeks of intervention,the rats were killed under anesthesia after echocardiography to detect cardiac function,and the heart tissues were taken for metabolomics detection.The differential metabolites and related pathways that may be related to liraglutide improving myocardial metab-olism in DCM rats were screened and enriched.Results Compared with normal control group,left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)in DCM group were significantly decreased,and the ra-tio of early to late diastolic mitralflow velocities(E/A)was significantly increased(P＜0.05).Compared with DCM group,LVEF and LVFS in LL group and HL group were significantly increased,and E/A ratio was significantly decreased(P＜0.05),suggesting that the impairment of left ventricular systolic and diastolic function in LL group and HL group was significantly alleviated.395 metabolites were detected by metabolomics,among which 239,116 and 187 different metab-olites and 13,6 and 20 metabolic pathways were enriched in DCM group and normal control group,LL group and DCM group,HL group and DCM group.In the above three groups,29 key differential metabolites were identified related to 3 metabolic pathways including choline metabolic pathway,caffeine metabolic pathway and valine,leucine and isoleucine bi-osynthesis pathway,among which choline metabolic pathway had the most significant differences.Conclusion These results indicated that liraglutide can ameliorate cardiac dysfunction in DCM rats through improving myocardial metabolism in which choline metabolism pathway may play a key role.

Objective:To evaluate oncological and reproductive outcomes of women ≤40 years undergoing fertility-sparing surgery (FSS) for stage Ⅱ or Ⅲ borderline ovarian tumor (BOT).Methods:The patients with BOT and ≤40 years old with stage Ⅱ-Ⅲ BOT who underwent FSS enrolled from the First Affiliated Hospital of Zhengzhou University between January 2011 and March 2023 were analyzed retrospectively. The clinical data and follow-up results were obtained and analyzed. The univariate and multivariate Cox proportional hazard regression analysis were used to explore high-risk factors associated with prognosis. Additionally, pregnancy outcomes were also analyzed.Results:(1) A total of 79 patients with stage Ⅱ-Ⅲ BOT who have been treated with FSS were conducted, with an average age of (27.5±6.7) years old. The median tumor maximum diameter were 10.4 cm (range: 4.8-90.0 cm). The International Federation of Gynecology and Obstetrics (FIGO) stage was stage Ⅱ in 45 cases and stage Ⅲ in 34 cases. According to the pathological types, there were 48 cases of serous tumor, 21 cases of mucinous tumor, 1 case of endometrioid tumor, and 9 cases of mixed types. There were 41 cases of unilateral ovarian involvement, 38 cases of bilateral ovarian involvement. There were 5 cases of microinvasion, 17 cases of micropapillary subtype. Extra-ovarian invasive implants were found in 5 cases, and there were 31 cases of merged ascites. (2) Tumor outcomes: the median follow-up time from primary cytoreduction were 58 months (range: 8-146 months). At the end of the observation period, 24 cases (30%, 24/79) recurred, among them 5 cases had two recurrences and 2 cases had three recurrences. There were 2 cases (3%, 2/79) of death and 1 case (1%, 1/79) of survival with tumor. (3) Analysis of prognostic risk factors: the results of univariate analysis showed that mucinous tumor, tumor maximum diameter >13.15 cm, FIGO stage Ⅲ, merged ascites, micropapillary subtype, invasive implantation, and bilateral ovarian involvement were independent risk factors (all P<0.05) for disease-free survival (DFS). FIGO stage Ⅲ ( HR=4.555, 95% CI: 1.525-13.607; P=0.007) and micropapillary subtype ( HR=2.396, 95% CI: 1.003-5.725; P=0.049) were found to be related to DFS through the multivariable Cox proportional hazard regression analysis. (4) Pregnancy outcomes: among the patients with fertility intentions 36 cases (46%,36/79), 29 cases (81%, 29/36) had successful pregnancies, and 27 cases (75%, 27/36) had successful births. Conclusions:Patients with stage Ⅱ-Ⅲ BOT underwent FSS have favorable survival and pregnancy rates. Micropapillary subtypes and FIGO staging (stage Ⅲ) are the significant risk factors of DFS.

Objective To investigate the changes in serum HP and ADMA levels in patients with ACI and the correlation of their levels with recanalization after venous thrombolysis and poor prognosis.Methods A total of 260 ACI patients undergoing venous thrombolysis in our hospital from January 2020 to March 2023 were retrospectively recruited,and were categorized into reper-fusion group(n=196)and non-reperfusion group(n=64)based on the efficacy of thrombolysis.After a 90-day follow-up,they were further divided into good prognosis group(n=159)and poor prognosis group(n=101)according to the results of a modified Rankin scale.Serum levels of HP and ADMA at admission were compared between the two groups.Logistic regression analysis was used to analyze the risk factors for non-reperfusion and poor prognosis in ACI patients.ROC curve analysis was performed to evaluate the predictive value of serum HP and ADMA levels for non-reperfusion and the diagnostic efficiency for poor prognosis in ACI patients.Results The non-reperfusion group exhibited notably elevated serum HP and ADMA levels than the reperfusion group(2.10±0.21 g/Lvs1.29±0.31 g/L,1.68±0.19 μmol/L vs 0.69±0.11 μmol/L,P＜0.01).HP and ADMA were identified as significant risk factors for uncanalization after treatment(P＜0.01).The AUC value of their combination in diagnosing uncanalization after venous thrombolys-is was 0.869(95％CI:0.830-0.908).Furthermore,significantly higher serum levels of HP and ADMA were observed in the poor prognosis group than the good prognosis group(2.27±0.19 g/L vs 1.15±0.34 g/L,1.72±0.21 μmol/L vs 0.64±0.10 μmol/L,P＜0.01).HP and ADMA were also recognized as influencing factors for poor prognosis in 90 d after treatment(P＜0.01).The AUC value was 0.816(95％CI:0.768-0.865)when their combination was used to predict poor prognosis in 90 d after treatment.Conclusion HP and ADMA are highly expressed in the se-rum of ACI patients with failed venous thrombolysis and poor prognosis.Their combined detec-tion can effectively predict both uncanalization and poor prognosis.

Objective:To evaluate the application value of preconceptional laparoscopic cervical cerclage(LCC)in improving the pregnancy outcomes with cervical incompetence(CIC).Methods:Clinical data of 112 pa-tients with CIC who underwent preconceptional LCC in The First Affiliated Hospital of Zhengzhou University from July 1,2014 to May 31,2023 were retrospectively reviewed.The surgical indications of preconceptional LCC in-cluded:failed transvaginal cervical cerclage(TCC)(42 patients),history of cervical surgery+failed TCC(7 pa-tients),unsuitability for TCC(10 patients)and strong request from patients(53 patients).The surgical situation and pregnancy outcome of preconceptional LCC were analyzed,and the gestational age of delivery before and af-ter preconceptional LCC surgery and different surgical indications were compared in postoperative delivery pa-tients who underwent preconceptional LCC.Results:The median operation time of 112 patients was 65.5 min,the median intraoperative blood loss was 10.0 ml,and there were no intraoperative complications.The postopera-tive hospital stay was 2.9±0.6 d.108 cases were followed up after surgery,with 77 cases of pregnancy and de-livery after LCC.A total of 205 deliveries were made before surgery,and 81 deliveries were made after surgery.Successful postoperative deliveries(delivery after 28 weeks)were 78(96.3% ),with an average gestational age 37.4±1.7 weeks.The preterm birth rate was 16.7%,term birth rate was 83.3% .The delivery rate at≥28 weeks after preconceptional LCC was significantly higher than the previous delivery rate of pre pregnancy LCC(96.3% vs.10.7%,P<0.05),and the gestational age was significantly prolonged(36.4±5.5 weeks vs.19.8±7.5 weeks,P<0.05).The postoperative delivery gestational week of preconceptional LCC with different surgical indi-cations was significantly later than the previous delivery gestational week of pre pregnancy LCC(P<0.05),ex-cept for the indication of unsuitability for TCC(P>0.05).Conclusions:Preconceptional LCC surgery is highly safe and can effectively prolong the gestational age and improve pregnancy outcomes in patients with CIC.It can be an effective treatment method for patients with a history of TCC failure.
