Objective: To investigate the association between frailty and type 2 diabetes mellitus (T2DM) using a bidirectional two-sample Mendelian randomization (MR) analysis, so as to provide the evidence for the prevention and control of frailty and T2DM. Methods: Frailty status was assessed using the Fried Frailty Score (FFS), with aggregated data sourced from 386 565 European samples in the UK Biobank. The T2DM data were obtained from the summary results of genome-wide analysis published by the Diabetes Genetics Replication and Meta-analysis Consortium, excluding the UK Biobank data, including 455 313 European samples. Eligible single nucleotide polymorphism site were selected from the FFS and T2DM summary data as instrumental variables. The bidirectional MR analysis was performed using the inverse-variance weighted method. The heterogeneity was assessed using the modified Cochran Q test. The horizontal pleiotropy of instrumental variables was examined using MR-Egger regression. The robustness of the results was evaluated using the leave-one-out method. The bias was tested using funnel plot. Results: The forward MR analysis revealed a statistically significant association between increased FFS and an increased risk of T2DM (OR=2.280, 95%CI: 1.169-4.447). The reverse MR analysis showed a statistically significant association between T2DM and increased FFS (β=0.026, 95%CI: 0.012-0.041). Both bidirectional MR results were robust, with no horizontal pleiotropy of the instrumental variables was found (all P>0.5); and the funnel plots did not show significant basis. Conclusion The study found a bidirectional causal association between frailty and T2DM.

Objective Amniotic membrane as the carrier to culture the vascular endothelial cells was investigated in this study in order to explore whether the corneal endothelial cells superseded by the vascular endothelial cells is feasible on the account of directing a kind of the original method to handle the bullous keratopathy.Methods The vascular endothelial cells adhering to the sphagitides lumen of the experimental rabbits were digested and gained by means of the perfusion method with 0.25%tripsin plus 0.02%EDTA.Fresh amniotic membrane without the amniotic epithelial cells was cut into the square tissue about 1.5 cm?1.5 cm and spread evenly in the 24-well culture dish.Primary cultured cells were subcultured on the amniotic membrane.We would not transplant the vascular endothelial cells feeding on the amniotic membrane until cells is full of the whole amniotic membrane surface.One to two months after the operation,the change of corneal diaphaneity was observed.Results About 12 days since the cell transplantation was performed,the corneal transparency alteration between the experimental groups and the control one is different.The corneal buttons in the experimental group show the severe edema and opacity,and the anterior chamber couldn't be seen unclearly.But,10 days after the operation,the corneal oedema which begins to extenuate was judged through the indicatrix that the corneal edema in the experimental group has been recovering slowly,among which the anterior chamber tissue of 7 animals was visible through the implant.The corneal edema in the control groups intensified evidently,even,the part of these appeared the ulcerous necrosis as result of the corneal severely edema.There is the existence of difference between two groups(P

Abstract: In order to investigate immune protection against swine-origin influenza virus (S-OIV) A H1N1, the helper-dependent adenovirus vector (HDAd) system was exploited to construct recombinant HDAd encoding hemagglutinin (HA). The HA gene was synthesized and cloned to the HDAd backbone. Then, the HDAd/HA DNA molecules were transfected into 293Cre4 cells with calcium phosphate. The cells were infected by helper virus 16 hours after the transfection. The 293Cre4 cells were coinfected with HDAd/HA and the helper virus for large-scale preparation of HDAd/HA. The HDAd/HA was obtained and purified twice with CsCI density ultracentrifugation and observed morphologically under transmission electron microscope, and the expression of HA protein was analyzed with RTPCR. Recombinant HDAd/HA expressing HA protein was successfully constructed which could pave the way for in vivo investigation on immunogenicity and efficacy against S-OIV A H1N1 infection.

Objective To comprehensively evaluate and compare the resuscitation efficacy of chest-compression-only cardiopulmonary resuscitation (CCPR) and standard cardiopulmonary resuscitation (SCPR) for patients with out-of-hospital cardiac arrest (OHCA). Methods Databases such as PubMed, Embase, Ovid, Cochrane Library, Wanfang, CNKI, VIP, CBM were searched from the date of their foundation to March 2nd 2018, and the studies on the difference of effects between CCPR and SCPR for patients with OHCA were retrieved. The outcomes included the return of spontaneous circulation (ROSC) rate, survival to hospital discharge, neurological function completion rate. Two reviewers independently screened the literature meeting the inclusion criteria, independently collected information and evaluated the literature quality. Meta-analysis was conducted using RevMan 5.3 software, and sensitivity analysis was conducted by selecting model analysis method and removing single research method. Funnel plot was used to evaluate publication bias. Results A total of 10 cohort studies were included, including 174 163 patients with OHCA, of which 95 157 undergone CCPR and 79 006 undergone SCPR. The scores of the Newcastle-Ottawa scale (NOS) were 8-9, indicating that the quality of the literatures included was high. It was shown by the Meta-analysis that CCPR had the higher rate of survival to hospital discharge [relative risk (RR) = 1.04, 95% confidence interval (95%CI) = 1.00-1.08, P = 0.04] and neurological function completion (RR = 1.11, 95%CI = 1.06-1.17, P < 0.000 1) than SCPR, but there was no significant difference in ROSC rate between the two groups (RR = 1.01, 95%CI = 0.98-1.04, P = 0.52). In the subgroup, there was no statistical significance between CCPR and SCPR in the rate of survival to hospital discharge in cardiac OHCA patients (RR = 1.13, 95%CI = 0.82-1.57, P = 0.45). However, in non-cardiac OHCA group, SCPR showed more benefits than CCPR in improving the rate of survival to hospital discharge (RR = 0.88, 95%CI = 0.80-0.96, P = 0.004). The above analysis results were consistent in the fixed effect model and random effect model, indicating that the results were reliable and stable. It was shown by the funnel plot that most of the studies were left-right inverted funnel type, indicating a low publication bias. However, the bias could not be completely excluded due to the small number of included literatures. Conclusions For patients without OHCA etiological classification, CCPR was not less than SCPR in improving ROSC rate, discharge survival rate and good neurological function, and CCPR was more advantageous in learning and the willingness of bystanders to implement. However, when non-cardiogenic OHCA could be identified, SCPR should be recommended when conditions permit.

Objective:To analyze the application and regularity of acupoint selection of Sanyinjiao (SP 6) based on data mining.Methods:Search for literatures in CNKI, Wanfang, VIP, and Pubmed, the clinical researches of acupuncture on Sanyinjiao (SP 6) point were selected, according to the inclusion and exclusion criteria, and the retrieval period was from database construction to September 30th, 2021. Excel 2016, SPSS Statistics 25.0, SPSS Modeler 18.0 were used to perform descriptive analysis, association analysis and cluster analysis.Results:After literature screening, a total of 261 literatures were included, involving 73 kinds of diseases, mainly including mental and behavioral disorders, genitourinary diseases, endocrine and nutritional metabolism diseases and nervous system diseases. The most frequently used acupoints in Sanyinjiao (SP 6) compatibility are Zusanli (ST 36), Baihui (GV 20), Guanyuan (CV 4) and Taichong (LR 3), most of which focus on stomach meridian, conception channel, governor channel and bladder meridian. Seven categories were extracted among high-frequency acupoints by cluster analysis. The association rule analysis showed that the commonly used combination of Sanyinjiao (SP 6) were Zusanli (ST 36)-Sanyinjiao (SP 6), Baihui (GV 20)-Sanyinjiao (SP 6), and Guanyuan (CV 4)-Sanyinjiao (SP 6).Conclusions:Sanyinjiao (SP 6) is widely used in clinical application, and it is always compatible with stomach meridian, conception vessel, governor channel acupoints, especially those acupoints on the outer and inner meridians and the upper and lower parts. Sanyinjiao (SP 6) combined with other acupoints can treat diseases of multiple systems, such as insomnia, stroke, anxiety and depression, dysmenorrhea, infertility, etc. Clustering and association analysis found the core compatibility law of Sanyinjiao (SP 6), which can be used as a reference for clinical acupoint selection.

The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling exert essential regulatory function in microbial-and onco-immunology through the induction of cytokines, primarily type I interferons. Recently, the aberrant and deranged signaling of the cGAS-STING axis is closely implicated in multiple sterile inflammatory diseases, including heart failure, myocardial infarction, cardiac hypertrophy, nonalcoholic fatty liver diseases, aortic aneurysm and dissection, obesity, etc. This is because of the massive loads of damage-associated molecular patterns (mitochondrial DNA, DNA in extracellular vesicles) liberated from recurrent injury to metabolic cellular organelles and tissues, which are sensed by the pathway. Also, the cGAS-STING pathway crosstalk with essential intracellular homeostasis processes like apoptosis, autophagy, and regulate cellular metabolism. Targeting derailed STING signaling has become necessary for chronic inflammatory diseases. Meanwhile, excessive type I interferons signaling impact on cardiovascular and metabolic health remain entirely elusive. In this review, we summarize the intimate connection between the cGAS-STING pathway and cardiovascular and metabolic disorders. We also discuss some potential small molecule inhibitors for the pathway. This review provides insight to stimulate interest in and support future research into understanding this signaling axis in cardiovascular and metabolic tissues and diseases.
