ABSTRACT
Objective To explore the possible effects of the microRNA(miR)-143/145 polymorphisms on cardiovascular risk factors and the severity of coronary heart disease(CHD) in Chinese Han people. Methods Polymerase chain reaction-restriction fragment length polymorphism analysis was employed to identify the genotypes of the rs353292 and rs4705343 polymorphisms for 380 patients with CHD and 163 CHD-free controls. The physiological and biochemical parameters between the genotypes were compared in the CHD patients and in controls,and the incidence of myocardial infarction(MI) was also compared between the genotypes in the CHD patients. Results The subjects with the rs353292 TT genotype had higher serum levels of triglycerides(F=3.00,P=0.05) and glucose(F=9.91,P<0.001) than the C carriers,and the subjects with the rs4705343 TT genotype had significantly higher prevalence of hypertension(Χ=6.35,P=0.04) than the C carriers in the control group. The patients with the rs353292 TT genotype had significantly higher serum levels of hypersensitive C-reactive protein(hs-CRP)(F=8.43,P<0.001) than the C carriers in the CHD group,and the frequency of MI was significantly higher in the patients with the rs353292 TT genotype than that in the C carrier patients(Χ=5.29,P=0.02). Conclusion The T allele of the rs353292 polymorphism is associated with serum hs-CRP levels in CHD patients,and it may affect the occurrence and development of MI by up-regulation of CRP gene through miR-143/145. The rs4705343 polymorphism is not related to the risk and severity of CHD.
ABSTRACT
Objective To improve the diagnosis and treatment of type Ⅰ autoimmune pancreatitis, a study was carried out to summarize the epidemiological characteristics, clinical manifestations and diagnosis of autoimmune pancreatitis (AIP).Methods This study retrospectively analyzed the clinical data of all the patients diagnosed with AIP from January 1998 to December 2016 in the ward of Peking union medical college hospital.Results 194 type 1 AIP patients were enrolled in this study.The M/F ratio of the disease was 3.51/1,with an average age of 57±15 years.The most common symptom is jaundice, abdominal pain and weight loss.The most common diseases of the pancreas are sclerosing cholangitis, salivary glands, IgG4 nephropathy.There are 36.68 percent of AIP patients with diabetes mellitus.IgG4, ANA, ESR, c-reactive protein and CA199 are all contribute to disease diagnosis and follow-up.Pathology, pet-CT and hormone therapy response all contribute to the diagnosis of AIP.Conclusions As a systemic disease, the type 1 AIP has special clinical features and laboratory profiles.The diagnosis of AIP can be applied in many ways.
ABSTRACT
Objective To investigate the antishock effect of oxygenate solution and its possible mechanism. Methods The protective effects of oxygenates hypertonic hypercolloid solution on lipid peroxidation injures in hemorrhagic shock in rabbits at 4 700 m high altitude spot was observed. Results The oxygenated solution treatment can obviously reduce the malondialdehyde(MDA) and glutathione(GSH) level in plasma and tissue ; and increase the superoxide diamutase(SOD) and glutathione peroxidase(GSH-PX) level in plasma and tissue of the hemorrhagic shock animals. Conclusions Oxygenatea solution treatment can reduce the lipid peroxidation injure, recover the equilibrium of oxidation and antioxidation with shock body in time, and promote the resuscitation of shock.
