ObjectiveTo analyze the long-term trends of the disease burden of diabetes attributed to metabolic factors in China from 1990 to 2019, and provide scientific recommendations for diabetes prevention and control in China. MethodsDescriptive analysis was conducted on the disease burden data of diabetes attributed to metabolic factors in China from 1990 to 2019, obtained from GBD 2019, encompassing death form diabetes, disability-adjusted life years (DALY), years of life lost (YLL), and years lived with disability (YLD). Joinpoint regression models were employed to analyze the long-term trends in mortality and DALY rates. Furthermore, the study examined the impact of two metabolic risk factors, high fasting plasma glucose (FPG) levels and high body mass index (BMI) levels, on the disease burden of diabetes. ResultsFrom 1990 to 2019, the overall standardized mortality and DALY rates attributed to metabolic factors for diabetes in the general population in China showed an upward trend, with both average annual percent changes (AAPCs) of 0.1% in the total population. The trend was upward in males with AAPCs of 0.9% and 0.6%, while it was downward in females with AAPCs of -0.4% and -0.3%. As age increased, the disease burden of diabetes attributed to metabolic factors showed an upward trend, with high FPG and high BMI ranking as the top two attributing risk factors. The disease burden of diabetes attributed to metabolic factors was higher in Chinese males than females. ConclusionThe disease burden of diabetes attributed to metabolic factors is increasing among the overall population and particularly among males, while the burden for female is declining. There is a need to increase intervention efforts for males aged 65 and above, provide scientific guidance on residents’ diet and lifestyle habits, and control blood glucose and body weight.

Objective To analyze how enterovirus D68 (EV-D68) protease 2A affects the anti-vi-ral interferon typeⅠ(IFN-Ⅰ) pathway in 293T cells following infection. Methods Western blot was used to detect the expression of recombinant protease 2A, IFN-α and signal transducers and activators of tran-scription 1 (STAT1) at protein level. Expression of EV-D68 viral protein (VP1) and protease 2A was ana-lyzed by immunofluorescence at different time points. Cytopathic effects were recorded to calculate 50％ cell culture infective dose ( CCID50 ) . Expression of the genes involved in the anti-viral IFN-Ⅰ pathway was measured by real-time PCR (RT-PCR). Results The recombinant plasmid pCLIPf-2A was successfully constructed and the expression of recombinant protease 2A could be detected by Western blot 24 h after transfection. The recombinant protease 2A promoted the proliferation of EV-D68 at the late stage of infection and induced the production of IFN-α. Expression of the genes involved in the anti-viral IFN-Ⅰ pathway at mRNA level was up- or down-regulated to different degrees with various trends in different groups following infection. Expression of STAT1 was enhanced in all groups. Conclusions EV-D68 protease 2A promoted the activation of anti-viral IFN-Ⅰpathway in response to viral infection and enhanced the proliferation of virus at the late stage of infection.

Objective To calculate and measure the depth and radius of the target vessel in the upper limb venous ultrasound image in order to contribute to automatic venipuncture.Methods Two methods of measuring the radius of veins in an ultrasonic vein cross section image were adopted.One method was to segment the vein based on the threshold selected after evaluation, and then scan the upper and lower edges of the vein to obtain the radius.The other method was based on Otsu method,which was to divide the vein and then morphologically process the binary image.The radius was calculated in a manner similar to the first method.After the radius was obtained, the depth of the vein was corrected in conjunction with the radius.Results The above two methods were tested on 500 upper limb venous ultrasound images.The accuracy rate of the first method was 93.0%, and that of the second method was 99.4%.Conclusion The method based on Otsu and morphological processing is more effective for radius measurement of veins in upper limb venous ultrasound image.

Objective To evaluate the change of renal function in patients with acute stroke by estimate glomerular filtration rate (e-GFR). Methods One hundred patients with acute stroke admitted into hospital from emergency department in 72 h were enrolled. There were 100 patients, with 50 male patients and 50 female patients. Fifty-eight patients were older than 50 years old, and 42 patients were less than 50 years. Blood samples were collected from the next day in hospital to detect the level of creatinine (Cr), then e-GFR was calculated with a simplified method of modification of diet in renal disease. According to the National Kidney Foundation published kidney disease outcome quality initiative (K/DOQI), the renal function of these 100 patients was estimated. The outcome of e-GFR and Cr were compared. The differences of e-GFR in patients with acute stroke were analyzed from the aspects of age and gender. Results 56.0% (56/100) patients were determined as decreased renal function according to the standard of GFR<90 ml/(min · 1.73 m2). 4.0% (4/100) patients were determined as decreased renal function according to the standard of Cr> 124μmol/L. The abnormal rate of e-GFR in patients older than 50 years old was 93.1%(54/58), in patients less than 50 years old was 4.8%(2/42), and there was significantly difference (χ2=77.16, P<0.01). The abnormal rate of e-GFR in male and female had no significantly difference: 54.0%(27/50) vs. 58.0% (29/50), P > 0.05. Conclusions The decreased renal function in patients with acute stroke is common. The detection of e-GFR can more accurately assess the patient′s renal function and provide a basis for individual choice of drugs.

The role of interleukin-17 (IL-17) in autoimmune hepatitis (AIH) was investigated. A mouse model of experimental autoimmune hepatitis was established, and the syngeneic S-100 antigen emulsified in complete Freud's adjuvant was injected intraperitoneally into adult male C57BL/6 mice. The IL-17 expression in serum and the livers of the mice models was detected by using ELISA and immunohistochemistry, respectively. IL-17 neutralizing antibody was used to study the biological effect of IL-17 in the experimental AIH. IL-17 neutralizing antibody in vivo administration alleviated the hepatic inflammation and ALT level in the AIH model. IL-17 in the peripheral blood mononuclear cells (PBMC) of AIH patients was measured by using real-time PCR method. The results showed that IL-17 level was significantly up-regulated in AIH patients and mice models. It was concluded that IL-17 contributed to the development of AIH and might be a potential therapeutic target of AIH.
