Association of serum adipokine CTRP6 in early pregnancy with gestational diabetes mellitus / 中国现代医生

@#Objective To study the expression levels of serum complement C1q/tumor necrosis factor-related protein 6(CTRP6)in women in early pregnancy and to explore its relationship with gestational diabetes mellitus(GDM).Methods Women at the Second Affiliated Hospital of Zhengzhou University from March 2021 to March 2022 were prospectively and consecutively selected from 10 to 13 weeks gestation for outpatient obstetric check-ups.The age,height,weight,and time of last menstruation of pregnant women were collected,and the levels of total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL),low density lipoprotein(LDL),fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),fasting insulin(FINS)and CTRP6 were measured in early pregnancy,and the pre-pregnancy body mass index(BMI),baseline BMI,prenatal BMI,and homeostatic model assessment of insulin resistance(HOMA-IR)were calculated.All pregnant women underwent a 75g oral glucose tolerance test at 24-28 weeks of gestation and were divided into GDM group and normal glucose tolerance(NGT)group according to the test results.The clinical data and laboratory indexes of the two groups in early pregnancy were compared,and the correlation between serum CTRP6 and various indexes in early pregnancy and its relationship with GDM were analyzed.Results A total of 213 maternal cases were enrolled,and 203 cases were completed for follow-up.Among them,52 mothers were diagnosed with GDM,with a GDM prevalence rate of 25.62%.Serum CTRP6,age,pre-pregnancy BMI,baseline BMI,antenatal BMI,TC,LDL,FPG,HbA1c,FINS,and HOMA-IR were higher in GDM group compared to NGT group,with a statistically significant difference(P<0.05).CTRP6 in early pregnancy was positively correlated with age,pre-pregnancy BMI,baseline BMI,prenatal BMI,TG,LDL,FPG,HbA1c,FINS,HOMA-IR,and negatively correlated with HDL(P<0.05).After correcting for age,BMI,glycolipid metabolism index and HOMA-IR,CTRP6 in early pregnancy remained an independent factor in the development of GDM.Conclusion Elevated serum CTRP6 in early pregnancy is associated with GDM and is an independent risk factor for GDM.

Mutation characteristics of rpoB gene in rifampicin-resistant Brucella strains / 中华地方病学杂志

Objective:To analyze the mutation characteristics of rpoB gene in rifampicin-resistant Brucella strains. Methods:DNA of 4 rifampicin-resistant Brucella strains (JSY-26, G-9, WSY-13 and AW-3) isolated from Xinjiang Uygur Autonomous Region was selected, rifampicin rpoB gene was amplified by PCR and its nucleotide sequence was sequenced. The rpoB gene sequences of rifampicin-resistant Brucella standard strain (RB51) and sensitive strain (ALT-8) were used as reference, the mutation sites and types of the rpoB gene inside and outside the rifampicin resistance determination region (RRDR) of the 4 rifampicin-resistant Brucella strains were analyzed by Mega 7.0 software. Results:Through sequence alignment, both JSY-26 and WSY-13 strains underwent a single base point mutation at the RRDR 1 576 bp of the rpoB gene, with the base changing from guanine (G) to adenine (A). The G-9 strain underwent a single base point mutation at the RRDR 1 606 bp of the rpoB gene, with the base changing from cytosine (C) to A. The AW-3 strain showed 5 mutations of 3 types outside rpoB gene RRDR at 2 536, 2 537, 2 626, 2 636 and 2 654 bp, namely 3 insertion mutations [thymine (T) insertion once and C insertion twice], 1 deletion mutation (C deletion), and 1 single base point mutation (from G to C mutation).Conclusion:The RRDR mutations in the rpoB gene of the rifampicin-resistant Brucella strains are mainly characterized by single base point mutations, while multiple insertion and deletion mutations occur outside the RRDR.

Construction of performance evaluation index system for outpatient capitation based on value-based payment / 中华医院管理杂志

Objective:To construct a performance evaluation index system of outpatient capitation under basic medical insurance in China based on the concept of value-based payment, so as to provide reference for the medical insurance departments to evaluate the performance of outpatient capitation.Methods:From January to February 2023, the initial index system was constructed based on literature research and expert discussion. Twenty experts were invited for 2 rounds of Delphi consultation and the index system was revised and improved, and the weight value of the index was determined by using analytic hierarchy process.Results:Seventeen experts completed the consultation. The final performance evaluation index system of outpatient capitation included 4 first-level indicators, 9 second-level indicators and 20 third-level indicators. In the first-level indicators, the weights of service delivery, medical costs, quality of care, and health outcomes were 0.234, 0.262, 0.262 and 0.242, respectively. The second-level indicators mainly included basic medical services, cost control, fund operation, quality of chronic disease management, etc. The index system not only included medical quality and cost control indicators, but also included several value-based indicators such as health outcomes and patient satisfaction.Conclusions:A performance evaluation index system for outpatient capitation has been successfully constructed, which simultaneously assesses the process and results of capitation, and can provide theoretical reference for the medical insurance departments to carry out performance evaluation.

Study of international experience in capitation performance evaluation framework and indicator system / 中华医院管理杂志

In order to ensure the smooth implementation of the capitation reform of outpatient clinics in China, it is urgent to establish a set of appropriate performance evaluation framework and index system. This study sorted out and described the capitation performance evaluation framework, index system content and payment rules of the United Kingdom, the United States, the Netherlands and Portugal, and conducted international comparison and analysis from the dimensions of service delivery mode, evaluation system, evaluation object, evaluation purpose, evaluation dimension, indicator setting, and incentive mechanism. Combined with the implementation status of the outpatient capitation payment reform in China, the following suggestions were put forward for the establishment of the outpatient capitation payment performance evaluation index system: introduce medical quality evaluation indicators based on value results, and link the evaluation results with the incentive mechanism; Select appropriate evaluation content based on the characteristics of the implementation institution and guarantee scope of the capitation reform and so on; The setting of evaluation indicators should be adjusted dynamically according to local conditions, and the combination of fixed indicators and personalized indicators should be explored; Adopt diversified index assessment forms and quality evaluation dimensions to ensure the statisticity and malleability of performance evaluation.

Game analysis on hospital outpatient payment methods of Chinese basic health insurance based on principle-agent theory / 中华医院管理杂志

As the major means of outpatient payment for basic medical insurance (the insurance for short) relies on fee-for-service, it tends to encourage unreasonable growth of medical expenses. Based on the principal-agent theory, this paper analyzed the principal-agent relationship between the insurance handling agencies and the hospitals designated by the insurance, and constructed a benefit game model of outpatient payment methods and the supporting supervision game model. This practice aims to explore the optimal and balanced benefit of the insurance payment methods and supporting supervision mechanism, and provide decision support for promoting the reform of medical insurance outpatient payment in China. The analysis results of the benefit game model of payment methods showed that a system mixing the post-payment and pre-payment could optimize and maximize the total benefits and interests of all the stakeholders within the system. Specifically, the practice recommended was a mixed payment integrating ambulatory-payment-classification, fee-for-service and global-budget-payment. The analysis of the supporting regulatory game model found that the factors that must be considered to ensure the expected utility of the above mixed payment mode as follows: the gap between the unreasonable income obtained by the hospital by out-of-control charging and the reward obtained by under-control charging, the size of the penalty after the unreasonable income of the hospital was discovered, the size of the regulatory cost and the loss of benefits of the government and the insured group. It is suggested to adopt the mixed payment method mainly based on the ambulatory-payment-classification supported by fee-for-service and global-budget. At the same time, medical insurance agencies can improve their supervision mechanism from such aspects as perfecting penalties, reducing supervision costs, leveraging government administrative power and advocating public supervision.

Decreasing complexity of glucose time series derived from continuous glucose monitoring is correlated with deteriorating glucose regulation / 医学前沿

Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual's health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique "continuous glucose monitoring" (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

The monitoring value of echocardiography for atrial septostomy during the treatment of extracorporeal membrane oxygenation / 中华超声影像学杂志

Objective:To investigate the monitoring value of echocardiography for atrial septostomy during the treatment of extracorporeal membrane oxygenation(ECMO).Methods:Sixteen patients underwent atrial septostomy during the treatment of ECMO in Wuhan Asia Heart Hospital from Jan.2017 to Dec.2019 were included. The diameter of the ostomy, the direction of interatrial shunt, the tricuspid regurgitation degree and the pulmonary artery pressure were measured by echocardiography daily after atrial septostomy.Results:There were no significant differences in the diameter of the ostomy in 16 patients(the range of coefficient of variation 0.86%-4.77%). The direction of interatrial shunt changed gradually from right - left atrial shunt to left - right atrial shunt. Pulmonary arterial pressure decreased gradually(the range of coefficient of variation 14.70%-32.13%) as estimated by tricuspid regurgitation pressure gradient.Conclusions:Atrial septostomy is an effective measure to relieve right heart pressure and improve right heart function in patients with ECMO. The echocardiography can be helpful for the monitoring of atrial septostomy.

Long non-coding RNA SAP30-2:1 is downregulated in congenital heart disease and regulates cell proliferation by targeting HAND2 / 医学前沿

Congenital heart disease (CHD) is the most common birth defect worldwide. Long non-coding RNAs (lncRNAs) have been implicated in many diseases. However, their involvement in CHD is not well understood. This study aimed to investigate the role of dysregulated lncRNAs in CHD. We used Gene Expression Omnibus data mining, bioinformatics analysis, and analysis of clinical tissue samples and observed that the novel lncRNA SAP30-2:1 with unknown function was significantly downregulated in damaged cardiac tissues from patients with CHD. Knockdown of lncRNA SAP30-2:1 inhibited the proliferation of human embryonic kidney and AC16 cells and decreased the expression of heart and neural crest derivatives expressed 2 (HAND2). Moreover, lncRNA SAP30-2:1 was associated with HAND2 by RNA immunoprecipitation. Overall, these results suggest that lncRNA SAP30-2:1 may be involved in heart development through affecting cell proliferation via targeting HAND2 and may thus represent a novel therapeutic target for CHD.

Low-carbohydrate diets lead to greater weight loss and better glucose homeostasis than exercise: a randomized clinical trial / 医学前沿

Lifestyle interventions, including dietary adjustments and exercise, are important for obesity management. This study enrolled adults with overweight or obesity to explore whether either low-carbohydrate diet (LCD) or exercise is more effective in metabolism improvement. Forty-five eligible subjects were randomly divided into an LCD group (n = 22) and an exercise group (EX, n = 23). The subjects either adopted LCD (carbohydrate intake < 50 g/day) or performed moderate-to-vigorous exercise (⩾ 30 min/day) for 3 weeks. After the interventions, LCD led to a larger weight loss than EX ( - 3.56 ± 0.37 kg vs. - 1.24 ± 0.39 kg, P < 0.001), as well as a larger reduction in fat mass ( - 2.10 ± 0.18 kg vs. - 1.25 ± 0.24 kg, P = 0.007) and waist circumference ( - 5.25 ± 0.52 cm vs. - 3.45 ± 0.38 cm, P = 0.008). Both interventions reduced visceral and subcutaneous fat and improved liver steatosis and insulin resistance. Triglycerides decreased in both two groups, whereas low-density lipoprotein cholesterol increased in the LCD group but decreased in the EX group. Various glycemic parameters, including serum glycated albumin, mean sensor glucose, coefficient of variability (CV), and largest amplitude of glycemic excursions, substantially declined in the LCD group. Only CV slightly decreased after exercise. This pilot study suggested that the effects of LCD and exercise are similar in alleviating liver steatosis and insulin resistance. Compared with exercise, LCD might be more efficient for weight loss and glucose homeostasis in people with obesity.

Application of an obesity evaluation index for the screening of type 2 diabetes mellitus / 中华健康管理学杂志

Objective This study investigated the application value of waist-to-height ratio (WHtR), body mass index (BMI), and waist-to-hip ratio (WHR) in screening for type 2 diabetes mellitus (T2DM) and high risk of T2DM. Methods A total of 7 582 subjects aged 40-75 years were randomly selected and stratified based on the results of an oral glucose tolerance test (OGTT) administered during a standard screening for T2DM in the Shougang community.Three anthropometric indices(WHtR,BMI,and WHR) were compared, with the optimal cutoffs for WHtR, BMI, and WHR identified using receiver operating characteristic curve (ROC) analysis. Using multivariate logistic regression analysis and the area under the curve(AUC)of ROC,the associations between BMI,WHR,and WHtR and T2DM were analyzed by group: normal glucose tolerance group (n= 3 080), T2DM high-risk group (n= 2 992 cases), and T2DM group(n=1 510).Results Logistic regression analysis showed that BMI,WHR,WHtR,and family history of diabetes were positively correlated with T2DM and high risk of T2DM(P<0.05 and P<0.01,respectively);WHtR was most significant, with odds ratios of 90.409 and 69.285, respectively. WHtR had the greatest AUC under the ROC in men,whereas BMI had the greatest AUC in women.The optimal cutoffs values for the detection of T2DM were 0.51, 25.47 kg/m2, and 0.91 for WHtR, BMI, and WHR in men, respectively, and 0.52, 24.95 kg/m2, and 0.86 for WHtR, BMI, and WHR in women, respectively. WHtR was more efficient than WHR and BMI based on the AUC. The optimal cutoff values for detecting a high risk for T2DM were 0.51,25.30 kg/m2,and 0.91 for WHtR,BMI,and WHR in men and 0.51,24.81 kg/m2,and 0.86 for WHtR, BMI, and WHR in women, respectively. Conclusion Waist-to-height ratio may be a more effective index for diagnosing type 2 diabetes mellitus and identifying individuals at high risk for T2DM than BMI or WHR.
