Objective:To investigate the association of time in range with metabolic associated fatty liver disease(MAFLD) and advanced liver fibrosis in patients with type 2 diabetes.Methods:This study was a retrospective study. A total of 494 type 2 diabetic patients were recruited in the Department of Endocrinololgy of Henan Provincial People′s Hospital from November 2019 to April 2022. Time in range(TIR) was calculated with continuous glucose monitoring data. Abdominal ultrasound scan was used to diagnose fatty liver. Liver stiffness measurement(LSM) by transient elastography was used to evaluate liver fibrosis. Pearson and multivariate linear regression analysis was used to evaluate the association between TIR and LSM. Multivariate logistic regression analysis was used to analyze the association of TIR with risk of MAFLD and advanced liver fibrosis.Results:Pearson correlation analysis showed that LSM was negatively correlated with TIR( r=-0.86, P<0.001) and was positively correlated with homeostasis model assessment for insulin resistance(HOMA-IR; r=0.48, P<0.001). After adjusting for confounding factors, multivariate linear regression analysis showed that TIR significantly negatively predicted LSM( β=-0.75, P<0.001), and HOMA-IR significantly positively predicted LSM( β=0.21, P=0.025). After adjusting for confounding factors, logistic regression analysis showed that compared with TIR Q4 patients, TIR Q1 patients had an increased risk of MAFLD( OR=1.96, 95% CI 1.07-3.62, P=0.027), advanced liver fibrosis( OR=3.82, 95% CI 1.17-12.50, P=0.027), and HOMA-IR was an independent risk factor for MAFLD( OR=1.22, 95% CI 1.04-1.43, P=0.005) and advanced liver fibrosis( OR=1.26, 95% CI 1.03-1.54, P=0.025). Conclusions:TIR and insulin resistance are independent risk factors for MAFLD and advanced liver fibrosis in patients with type 2 diabetes. TIR has a significant predictive value for MAFLD and advanced liver fibrosis.

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.

Objective:To investigate the association between time in target range and risk of vertebral fracture in patients with type 2 diabetes.Methods:The clinical data of 1 032 patients with type 2 diabetes who were hospitalized in endocrine department of Henan Provincial People′s Hospital from June 2017 to July 2021 were collected. Among which 632 patients were included into final analysis. The diabetes-specific risk score for vertebral fracture was used to assess the risk of vertebral fracture. Multivariate linear regression analysis was used to test the association between time in target range and risk score of vertebral fracture. Risk score≥9 was defined as increased risk of vertebral fracture. Multivariate logistic regression was used to estimate the association between time in target range and risk of vertebral fracture. Results:Among the included patients, mean age was(55.0±12.4) years and the percent of male was 72.5%. The mean course of diabetes was(9.4±8.0) years, and mean score of risk of vertebral fracture was 5.6±4.3. Time in target range was negatively correlated with risk score of vertebral fracture( P for trend <0.001), which was independent of potential confounders and continuous glucose monitoring parameters. The included patients were divided into four groups based on quartiles of time in target range. Multivariate logistic regression indicated that the risk of vertebral fracture in the first quartile of time in target range was 4.6 times higherthanthatinthe4thquartile, and the significance remained adjusted for potential confounders, s, CV, or meanamplitudeofglycemicexcursions(MAGE), respectively. Conclusion:Timein target rangewasnegativelycorrelatedwithriskscoreofvertebralfracturein patient with type 2 diabetes. Low time in range level was an independent risk factor for increased risk of vertebral fracture.

Diabetic kidney disease is a severe microvascular complication of diabetes characterized by complex etiology, diverse mechanisms, long course, and poor prognosis, posing a significant threat to patients′ quality of life. In recent years, research on gut microbiota has progressed deeper, and the concept of the gut-kidney axis emerges, introducing novel therapeutic concepts. This article provides an overview of the role of gut microbiota in the development of diabetic kidney disease and explores potential therapeutic strategies involving gut microbiota for the treatment of this condition.

Objective:To explore the effect of dyslipidemia on the clinical outcome of intracytoplasmic sperm injection-embryo transfer (ICSI-ET) in infertility patients receiving donor eggs.Methods:A total of 118 patients were selected to receive egg donors and ICSI-ET at the First Affiliated Hospital of Nanjing Medical University between April 2007 and December 2020. According to the levels of triacylglycerol, serum cholesterol, high density lipoprotein (HDL), and low density lipoprotein, they were divided into dyslipidemia group (35 cases) and normal blood lipids group (83 cases). The influence of body mass index (BMI) and age was adjusted by 1∶1 propensity score matching, and the general condition and clinical outcome of the two groups were analyzed retrospectively. Finally, the relationship between lipid composition and clinical outcome was analyzed according to patients′ age and BMI.Results:(1) Comparing the pre-matching dyslipidemia group with the normal blood lipids group, the BMI of the dyslipidemia group was significantly higher than that of the normal blood lipids group [(23.5±2.4) vs (22.4±2.7) kg/m 2], and the embryo implantation rate was significantly lower than that of the normal blood lipids group [13.6% (8/59) vs 27.3% (36/132)], the differences were statistically significant (both P<0.05). (2) There were no significant differences in years of infertility, number of pregnancies, number of abortions, number of transplanted embryos, protocol of endometrial preparation, endometrial thickness on transplantation day and high quality embryo rate between the two groups, through propensity score matching (all P>0.05). The biochemical pregnancy rate [28.6% (10/35)], embryo implantation rate [13.6% (8/59)] and live birth rate [20.0% (7/35)] in dyslipidemia group were significantly lower than those in the normal blood lipids group ( P<0.05). The clinical pregnancy rate was lower than that of the normal blood lipids group ( P>0.05). (3) The results of stratified analysis showed that the level of HDL in the clinically non-pregnant group was significantly lower than that in the pregnant group in patients ≤ 35 years old [(1.5±0.3) vs (1.8±0.5) mmol/L; P<0.05]. In the overweight recipient patients, the level of HDL of the clinically non-pregnant group was lower than that of the pregnant group ( P>0.05). Conclusions:Dyslipidemia significantly reduces the biochemical pregnancy rate, embryo implantation rate and live birth rate in patients with receiving donor eggs. Especially in patients aged ≤35 years old, the reduction of HDL is closely related to adverse pregnancy outcomes.

Objective:To analyze the correlation between two-dimensional ultrasound and HbA1c, Thyroid stimulating hormone (TSH) and its diagnostic value in benign and malignant Thyroid nodules.Methods:A total of 155 patients with thyroid nodules examined in the Department of Ultrasound Medicine of Haikou Orthopedics and Diabetes Hospital from January 2020 to January 2021 were prospectively selected. With surgical pathological examination as the gold standard, they were divided into benign group (75 cases) and malignant group (80 cases) according to the nature of nodules. There were 40 males and 35 females in the benign group, with an age of (47.95±8.26) years old and BMI of (22.45±1.26) kg/m2. There were 42 males and 38 females in the malignant group, with an age of (48.22±8.01) years old and BMI of (22.36±1.21) kg/m2. The expression level of HbA1c was detected by automatic biochemical analyzer, and the concentration of TSH was detected by automatic immunoassay. SPSS 19.0 statistical software was used for analysis and processing.Results:Compared with benign thyroid nodules, the mean transit time (MTT) and time to peak intensity of malignant thyroid nodules were (0.92±0.11 vs 1.48±0.42) s and (1.48±0.42) s respectively. TIP (1.06±0.21 vs 1.57±0.56) s, perfusion Index (PI) (1.15±0.22 vs 1.76±0.62) s parameters increased, and the differences were statistically significant ( P < 0.05) . Compared with patients with benign thyroid nodules, the expression levels of HbA1c (6.98±0.73 VS 10.22±1.35) % and TSH (3.95±0.53 VS 8.75±0.95) mIU/L in patients with malignant thyroid nodules were significantly higher ( P<0.05) . The expression levels of MTT, TIP, PI, HbA1c, and TSH were correlated with those of benign and malignant thyroid nodules, and the expression levels of MTT, TIP, PI, HbA1c, and TSH were positively correlated with those of benign and malignant patients ( P<0.05) . MTT, TIP and PI had correlation with the expression levels of HbA1c and TSH. Positive correlation: MTT had a positive correlation with HbA1c and TSH. TIP had a positive correlation with HbA1c and TSH. PI had a positive correlation with HbA1c and TSH ( P<0.05) . Compared with the single diagnosis of MTT, TIP and PI, the three combinations had higher diagnostic value for malignant thyroid nodules ( P=0.001) . Conclusion:Two-dimensional ultrasound parameters have high diagnostic value in malignant thyroid nodules, and have certain correlation with HbA1c and TSH, which can be used for the diagnosis of malignant thyroid nodules.

Objective:To investigate the association of time in range(TIR) with the severity of coronary artery disease and acute coronary syndrome in patients with type 2 diabetes mellitus.Methods:A total of 216 patients with type 2 diabetes mellitus and coronary heart disease were recruited and undergone anthropometric and biochemical measurements, continuous glucose monitoring, and calculation of SYNTAX score. TIR was defined as the percentage of time within the glucose range of 3.9-10.0 mmol/L during 24 h. Spearman correlation analysis and multivariate linear regression analysis were used to evaluate the correlation factors of SYNTAX score. Multivariate logistic regression analysis was used to analyze the association of TIR with the severity of coronary artery disease and acute coronary syndrome. Results:Compared with patients with mild coronary artery disease, TIR in patients with moderate to severe coronary artery disease was lower[(69.4±17.3)% vs (60.8±17.8)%, t=3.0, P=0.003], and HbA 1C of patients with moderate to severe coronary artery disease was higher [(9.6±1.7)% vs (8.8±1.6)%, t=3.3, P=0.001]. SYNTAX score was negatively correlated with TIR ( r=-0.251, P<0.01) and positively correlated with HbA 1C ( r=0.249, P<0.01). Moreover, compared with HbA 1C (standardized coefficients=0.181, P=0.007), TIR (standardized coefficients=-0.192, P=0.004) had a greater influence on SYNTAX score. Multivariate linear regression analysis showed that TIR, HbA 1C, duration of diabetes and smoking were independently correlated with SYNTAX score. Multivariate logistic regression analysis revealed that compared with TIR Q1, Q3 and Q4 were independent protective factors for moderate to severe coronary artery disease (respectively, OR=0.61 and 0.59, 95% CI 0.39-0.96 and 0.38-0.94, P=0.014 and 0.009) and acute coronary syndrome (respectively, OR=0.51 and 0.39, 95% CI 0.32-0.95 and 0.26-0.75, P=0.022 and 0.008). Conclusion:TIR was significantly and independently correlated with the severity of coronary artery disease and acute coronary syndrome in type 2 diabetes mellitus after controlling confounding factors. When TIR level was decreased, the severity of coronary artery disease was aggravated, and SYNTAX score and the risk of acute coronary syndrome was increased.

The clinical data of 239 inpatients with type 2 diabetes in Endocrinology Department of Henan Provincial People′s Hospital from January to February 2017 were collected. A total of 170 subjects were included in the final analysis. One diabetes-specific vertebral facture risk estimation called risk score for vertebral fracture was used to estimate the risk of vertebral fracture. Multivariate linear regression analysis was used to calculate the association of serum uric acid with risk of vertebral fracture. The mean age of subjects in final analysis was 56.5±26.4 years old, with the duration of diabetes 8.6±7.1 years and the vertebral fracture risk score 5.6±4.0. Additionally, there was a negative linear correlation between serum uric acid and vertebral fracture risk score in patients with type 2 diabetes( Ptrend=0.021) independent of age, gender, systolic blood pressure, HbA 1C, course of diabetes, obesity status, total cholesterol, and estimated glomerular filtration rate( P=0.033). Multivariate linear regression indicated that age, course of diabetes, blood pressure, total cholesterol, serum albumin, T score at femoral neck were related to the vertebral fracture risk score.

Objective:To investigate the correlation between serum calcium levels and severity of novel coronavirus pneumonia(COVID-19).Methods:The clinical data of 165 COVID-19 patients diagnosed from January to February 2020 were analyzed retrospectively. Combined with clinical classification, the differences of various indexes between the critically ill group and the control group were compared, and the influencing factors of disease severity were analyzed by multivariate logistic regression. According to the corrected serum total calcium levels, patients were divided into low calcium group and normal calcium group, and the related indexes of the 2 groups were compared for further analyzing the causes of hypocalcemia. Results:Compared with the control group, the age, diabetes, basic respiratory disease, and cardiovascular disease ratio, C-reactive protein(CRP), fasting blood glucose(FPG), interferon γ(IFN-γ), and interleukin 17(IL-17) levels increased while the lymphocyte percentage, serum albumin(ALB), corrected calcium levels, CD4 + T cells percentage, CD8 + T cell percentage decreased, the difference was statistically significant( P<0.05). There was no significant statistical difference in gender between the two groups, hypertension ratio, alanine aminotransferase(ALT), glomerular filtration rate(eGFR), CD4 +/CD8 + ratio and interleukin 4(IL-4) levels( P>0.05). The decrease of calcium level, age and eGFR were all risk factors for COVID-19 patients. Compared with the normal calcium group of COVID-19 patients, the level of ALB, CD4 + T cells percentage, CD8 + T cell percentage in low calcium group decreased and age, proportion of critically ill patients, diabetes, basic respiratory disease and cardiovascular disease ratio and CRP level all increased, the differences were statistically significant( P<0.05), and there was no statistical difference in the other biochemical indexes( P<0.05). Conclusion:There are obvious hypocalcemia and immune dysfunction in critically ill patients of COVID-19, and close monitoring of blood calcium levels may predict the severity of the disease more effectively
