Objective This study examined changes in serum growth hormone(GH)and insulin-like growth factor 1(IGF-1)levels,as well as insulin resistance,in patients with type 2 diabetes mellitus(T2DM)across different stages of diabetic kidney disease(DKD).It explored the relationship between these factors and the occurrence and progression of DKD,with the aim of identifying new targets for the prevention and treatment of DKD.Methods In this cross-sectional study,T2DM patients aged 18-80 years were selected from the Department of Endocrinology,The Second Affiliated Hospital of Xi'an Jiaotong University,from November 30,2019 to March 30,2021.Their serum GH and IGF-1 levels were tested.Results The serum GH level increased gradually in the groups,and the difference was statistically significant(P＜0.05).The level of serum IGF-1 decreased first and then increased among the groups,but with no significant difference(P＞0.05).HOMA-IR showed no significant correlation among the groups(P＞0.05),but HOMA-β gradually decreased among the groups,with statistically significant difference(P＜0.05).Multivariate Logistic regression analysis showed that the increase of serum GH level was closely related to the progression of T2DM to early DKD,and that the increase of serum IGF-1 level might be related to the deterioration of renal function in patients with T2DM at DKD stage.HOMA-IR and HOMA-β were not found to have correlation with the occurrence or development of DKD in T2DM patients.Conclusion In patients with T2DM,elevated serum GH level is closely associated with the occurrence and progression of early DKD.The increase of serum GH level may promote the occurrence of early DKD in T2DM,and the increase of serum IGF-1 level may be related to the deterioration of renal function in clinical DKD stage.In this study,we did not find correlation of HOMA-IR and HOMA-β with the occurrence or development of DKD in T2DM patients.

Objective To investigate the correlation between perioperative oxygen concentration and postoperative organ injury and other adverse reactions in children undergoing neurosurgery.Methods This study is a single-center retrospective cohort study,including 512 children aged≤14 years and operating duration≥2 hours who were transferred after surgery to postanesthesia care unit(PACU),Department of Anesthesiology,Beijing Tiantan Hospital,Capital Medical University from October 2018 to September 2023.His electronic medical record system was used to review and collect the patient's medical records during hospitalization.Including baseline data,anesthetic use,duration of anesthesia,intraoperative oxygen concentration,postoperative diagnosis,and surgical method;blood pressure,heart rate,oxygen saturation,pain score and special conditions during anesthesia recovery;infection during postoperative hospitalization(including wound infection,intracranial infection),respiratory complications[confirmed by chest radiograph/chest computed tomography(CT)report],changes in renal function(first postoperative serum creatinine value-last preoperative serum creatinine value),and incidence of delirium during recovery period during anesthesia were recorded.The area under oxygen concentration-time curve area under curve AUCFiO2=the product of intraoperative oxygen concentration(%)and duration of anesthesia(min)was calculated,and then 512 children were divided into 3 groups according to the AUCFiO2 tripartite(group 1:AUCFiO2<8 720%min,group 2:8 720%·min≤AUCFiO2≤13 800%·min,group 3:AUCFiO2>13 800%·min)were included in the data analysis.Results The incidence of emergency delirium(ED)during postoperative recovery was 24%,26.9%and 19.4%,and the incidence of acute kidney injury(AKI)was 0.6%,2.3%and 0.6%,respectively.There was no significant difference between the three groups(P>0.05).The incidence of postoperative pulmonary complications in the three groups was 20.6%,20.8%and 31.5%,respectively,and there was significant statistical difference among the three groups(P<0.05).There were no significant differences in nausea,vomiting,hypoxemia,and PACU residence time among the three groups during anesthesia recovery room(P>0.05),and there were significant differences in intracranial infection,wound infection and hospital stay during hospitalization(P<0.05).Conclusion Although oxygen concentration AUCFiO2 has no correlation with the occurrence of postoperative AKI and ED,the longer the exposure time of conventional oxygen administration strategy,the higher the incidence of postoperative pulmonary complications and postoperative infection,and the longer the hospitalization time of children.

In clinical practice, TCM external treatment is used to treat cancer pain, malignant pleural effusion, cancer-related fatigue and other related diseases of non-small cell lung cancer (NSCLC). TCM external treatment can also prevent and treat adverse reactions related to NSCLC treatment measures, such as postoperative cough, radiation-induced lung injury, nausea and vomiting after chemotherapy, bone marrow suppression after chemotherapy, immune and targeted drug-related rash, etc. It mainly uses external use of Chinese materia medica, acupuncture, moxibustion, scraping, acupoint pressing and other methods. Different TCM external treatment method are often used in combination to improve the curative effect. External therapy has been widely used in the treatment of NSCLC related diseases. By balancing yin and yang of viscera, promoting the recovery of body function, it can achieve the role of cancer prevention, improvement of quality of life, control of clinical symptoms, attenuation and effect enhancement.

Objective:To investigate the prevalence of infertility and the factors affecting it in women of reproductive age in Qinghai Province.Methods:From July to December 2024, a multi-stage stratified cluster random sampling approach was used to recruit women aged 20-49 years in 10 districts across 8 cities in Qinghai Province for a questionnaire survey assessing the prevalence of infertility. Univariate and multivariate binary logistic regression analyses were then performed to identify factors associated with infertility in Qinghai Province.Results:A total of 3 925 questionnaires were distributed, with 3 837 valid responses ultimately collected. Preliminary screening identified 581 infertility cases, yielding an infertility rate of approximately 15.1%. Among these, 170 cases were primary infertility and 411 were secondary infertility, accounting for 29.26% and 70.74% of infertility cases, respectively. The highest infertility rate was observed in Yushu City, Yushu Prefecture, at 26.1% (71/272), followed by Chengxi District, Xining City at 25.3% (174/688). The lowest infertility rate was recorded in Delingha City, Haixi Prefecture, at only 2.9% (9/311). Univariate analysis revealed that household registration status ( P<0.001), age ( P=0.016), age at marriage ( P=0.001), highest educational attainment ( P<0.001), per capita annual income ( P=0.001), body mass index (BMI, P=0.005), altitude ( P<0.001), age at menarche ( P=0.011), menstrual regularity ( P<0.001), menstrual cycle ( P=0.001), menstrual duration ( P<0.001), presence of blood clots ( P<0.001),whether the women smoking ( P=0.008), whether the women staying up late ( P=0.022), and whether the husband staying up late ( P<0.001) were independent factors for infertility. Multivariate binary logistic regression analysis revealed that non-agricultural household registration ( OR=1.637, 95% CI: 1.304-2.054, P<0.001), BMI≥24.0 kg/m2 ( OR=1.326, 95% CI: 1.077-1.632, P=0.008), age at menarche >14 years ( OR=1.405, 95% CI: 1.158-1.705, P=0.001), irregular menstrual cycles ( OR=1.512, 95% CI: 1.127-2.029, P=0.006), menstrual cycle <21 d ( OR=1.572, 95% CI: 1.237-1.998, P<0.001), menstrual duration <7 d ( OR=2.080, 95% CI: 1.529-2.831, P<0.001), and smoking ( OR=2.359, 95% CI: 1.056-5.271, P=0.036) were independent risk factors for infertility. Age and altitude were not independent risk factors for infertility in Qinghai Province. Conclusion:The prevalence of infertility in Qinghai Province is approximately 15.1%. Non-agricultural household registration, BMI≥24.0 kg/m2, age at menarche >14 years, irregular menstrual cycles, menstrual cycle <21 d, menstrual duration <7 d, and smoking are factors influencing infertility, while high altitude does not increase the risk of infertility among women in Qinghai Province.

Objective:To investigate the prevalence of hyperuricemia (HUA) in Bozidun Kirghiz township of Xinjiang Aksu region, and to explore the risk factors for the occurrence of HUA in the local area.Methods:A cross-sectional survey study was conducted by randomly selecting 9 villages in Bozidun Kirgiz Township by the whole-group sampling method and questionnaire were distributed to the households. The questionnaire included: demographic information, history of past illness, personal history, and all subjects were measured for height, weight, blood pressure, abdominal circumference, etc. The diagnostic of HUA if the serum uric acid (SUA) level >420 μmol/L in men or >360 μmol/L in women. The incidences of HUA in different age, sex, food type and life style behavior were analyzed. T test, non-parametric test and Chi-square test were used to analyze the differences among the groups, and logistic regression was used to analyze the risk factors. Results:①A total of 2 138 subjects were surveyed, among which 68 patients were with HUA, the prevalence of HUA in Bozidun Kirghiz township, Aksu region in the general population was 3.18%(68/2 138); the prevalence rate in men was 4.60%(45/978), 45 patients were identified; and the prevalence rate in women was 1.98%(23/1 160), 23 patients were identified. The peak age of HUA in male and female patients was 51~60 years old. ②The prevalence of HUA was lower in those who consumed dairy products ( χ2=6.91, P=0.017), nuts ( χ2=8.43, P=0.038) and eggs ( χ2=7.38, P=0.023), and lower in those who consumed more. Different intake of cereals ( χ2=0.87, P=0.647), meat( χ2=0.82, P=0.662), vegetables and fruits( χ2=5.22, P=0.073) had no effect on the prevalence of HUA.③In terms of different life behaviors, the prevalence of HUA in men who had been smoking was higher than those who had never smoked (57.78%, 28.89%, 13.33%, χ2=8.16, P=0.017). In the relationship between drinking and HUA, the prevalence rates of male always drinking, ever drinking and never drinking were 80.00%, 11.11% and 3.89%, respectively, the difference was statistically significant ( χ2=6.67, P=0.038). ④Multi-factor logistic regression analysis showed that high BMI, old age, high TG, increased Cr and increased WBC were risk factors for the occurrence of HUA [ OR(95% CI)=1.13(1.04, 1.23), 1.03(1.00,1.05),1.39(1.00, 1.93), 1.03(1.02, 1.05), 1.27(1.07, 1.49), all P<0.05]. Conclusion:The prevalence of HUA in Bozidun Kirgiz township in Aksu prefecture of Xinjiang is lower than that in other areas with continental climate. High BMI, old age, high TG, increased Cr and increased WBC count are risk factors for the development of HUA .

Objective:To investigate the levels and clinical significance of insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3) in the serum of patients with rheumatoid arthritis (RA).Methods:Serum samples from 82 patients with RA admitted to the Affiliated Dongyang Hospital to wenzhou Medical Umiversity from December 2019 to February 2022 were collected as the experimental group and the serum of 45 healthy individuals from the physical examination center as the control group. Serum levels of IGF2BP3 were measured using enzyme-linked immunosorbent assay (ELISA), and the t-test was used to compare the difference in IGF2BP3 levels between the two groups. The value of IGF2BP3 in the diagnosis of RA was analyzed by plotting a ROC curve, and after determining the cut-off value, serum IGF2BP3 levels were divided into high and low levels. The relationship between serum IGF2BP3 levels and various clinical features of RA patients was then analyzed using the chi-square test. Results:The serum levels of IGF2BP3 in RA patients were significantly higher compared to healthy controls [(0.60±0.55)ng/ml vs. (0.31±0.17)ng/ml, t=4.42, P<0.001]. The cut-off value of IGF2BP3 was determined as 0.308 ng/ml. The high level of IGF2BP3 was significantly more prevalent in active RA patients (78.8%, 41/52) than in non-active patients (56.7%, 17/30) ( χ2=4.52, P=0.033). The level of IGF2BP3 was positively correlated with the C-reactive protein level ( r=0.29, P=0.008), and the prevalence of high IGF2BP3 level in the elevated CRP group (82.0%, 41/50) was significantly higher than that in the decreased CRP group (54.8%, 17/31) ( χ2=6.94, P=0.008). The AUC of the ROC curve for serum IGF2BP3 in the diagnosis of RA was 0.700, with a sensitivity of 70.7% and a specificity of 60.0%. When using 0.575, 0.689, and 0.727 ng/ml as the cut-off values for serum IGF2BP3, the sensitivity was 34.1%, 26.8%, and 23.2%, respectively, with the specificity of 95.6%, 97.8%, and 100.0%, respectively. Conclusion:The level of serum IGF2BP3 is closely associated with RA disease progression.
