ObjectiveTo study the effect of responded hyperglycemia on the prognosis of acute stroke.Methods116 cases with acute stroke were divided into responded hyperglycemia group and normoglycemia group.The complications and activity of daily living(ADL) were compared in these two groups.ResultsResponded hyperglycemia severely influenced the recovery of patients as well as diabetes mellitus did.The incidence of infective complications in responded hyperglycemia group was higher than that of normoglycemia group.ConclusionsResponded hyperglycemia can make the prognosis of acute stroke bad.

Objective To study the correlation of multi-slice CT portography (MSCTP) and digestive endoscopy in the diagnosis and evaluation of esophageal and gastric varices (EGV) caused by cirrhosis.Methods A total of 92 patients with cirrhosis were enrolled in the prospective study.All the patients were examined by endoscopy and 64-slice spiral CT scan in 4 weeks.The types,grading of EGV were observed by endoscopy and MSCTP,and Kappa conformance test was applied with the endoscopic findings as gold standard.The sensitivity,specificity,consistency,and Youden index were evaluated for the diagnosis of sophageal and gastric varices by MSCTP.Results Sixty-five patients were diagnosed to have EGV by endoscopy and 27 were negative.The positive patients included 45 patients of GOV1,19 of GOV2 and 1 patient of IGV1.MSCTP diagnosed 67 cases of EGV and 25 patients of negative results.The positive patients included 46 of GOV1,18 of GOV2 and 3 of IGV1.Two patients of IGV1 varicose veins without positive findings on endoscopy were diagnosed by using MDCTP,which revealed isolated varicose veins under the gastric mucosa.There was high consistency between MSCTP and EGV in the diagnosis of EGV (Kappa =0.732,P ＜ 0.01).The sensitivity of MSCTP was 93.8％,specificity was 77.8％,consistency was 89.1％,and Youden index 71.6％.There was high consistency between MSCTP and EGV in the classification of EGV (Kappa values were 0.743 and 0.763,P ＜ 0.01).Conclusions There is high consistency between MSCTP and digestive endoscopic in the diagnosis and classification of EGV in cirrhosis.MSCTP is superior to endoscopy in the detection of gastric varices.

OBJECTIVETo investigate changes in the expression of sarcoplamic reticular Ca(2+)-ATPase (SERCA) and IP(3)-I receptors (IP(3)R(1)) mRNA in patients with atrial fibrillation.

METHODSThirty-eight patients with mitral stenosis undergoing open heart surgery were studied. 100 mg of atrial tissue was obtained during surgery from the right appendage and the right atrium. The amount of messenger ribonucleic acid (mRNA) amount of SERCA and IP(3)R(1) was measured by reverse transcription-polymerase chain reaction (RT-PCR) and normalized to the mRNA levels of glyceraldehyde 3-phosphate dehydrogenase (GAPDH).

RESULTSLevels of mRNA expression of SERCA in patients with AF, as compared with subjects in sinus rhythm, was lower and that of IP(3)R(1) was higher. The longer AF was sustained, the higher the levels of mRNA. There was no significant difference between right atrial free wall and right appendage.

CONCLUSIONSThe expression changes of SERCA and IP3R mRNA may correlate with the initiation or maintenance of AF.

A group of 19 referred hypertensive patients were diagnosed to have primary aldosteronism(PA) with inconclusive computed tomography scan results.Adrenal vein sarmpling (AVS) was performed in all patients.AVS was successful in 16 cases but failed in 3 cases.According to the results of AVS and postoperative pathology,8 cases were diagnosed as aldosterone-producing adenoma (APA) and unilateral adrenal hyperplasia (UAH),and the other 8 cases were diagnosed as idiopathic hyperaldosteronism (IHA).In conclusion,AVS is one of the most crucial methods in typing diagnosis of PA.

Objective To use in vitro experiments to verify the changes of proliferation, senescence and apoptosis of hepatocellular carcinoma cells after inhibiting the expression of NEK7, and to explore the related molecular mechanism. Methods Western blot and RT-PCR were used to detect the expression of NEK7 in hepatocellular carcinoma cells and THLE-2 cells. A viral vector was designed to inhibit the expression of NEK7 based on the gene sequence. After hepatocellular carcinoma cells were transfected, we observed the changes of proliferation activity, cell senescence, cell apoptosis and cell cycle in vitro. Western blot was used to detect the expression of cell cycle-related factors. Results Compared with THLE-2 cells, NEK7 was highly expressed in hepatocellular carcinoma cells. After inhibiting the expression of NEK7 with shRNA, the proliferation of hepatocellular carcinoma cells was inhibited, the proportions of cell senescence and apoptosis were increased, meanwhile, the cell number in stage S and G₂/M was significantly reduced, the cell cycle progression was blocked, the expression levels of C-myc, c-Fos, cyclin D1 and cyclin E were inhibited, P16 and P27 expression were increased, and CDK2, CDK4 and CDK6 expression were not significantly changed. Conclusion After inhibiting the expression of NEK7, the proliferation ability of hepatocellular carcinoma cells is reduced, cell senescence is promoted and apoptosis is induced; meanwhile, the cell cycle progress is blocked.

In 2016, a national one million general population cohort project was set up in China for the first time in "Precision Medicine Research" Key Project, National Key Research and Development Program of China, which consists of general population cohorts in seven areas in China. As one of the seven major areas in China, northeastern China has unique climate and specific dietary patterns, and population aging is serious in this area. And the burden of chronic and non-communicable diseases ranks tops in China. Therefore, it is of great significance to establish a large general population cohort in northeastern China to explore the area specific exposure factors related to pathogenesis and prognosis of chronic and non-communicable diseases, develop new prevention strategies to reduce the burden of the diseases and improve the population health in northeastern China. In July 2018, the general population cohort study in northeastern China was launched, the study includes questionnaire survey, health examination and blood, urine and stool sample collection and detection in recruited participants. By now, the cohort has covered all age groups, and the baseline data of 115 414 persons have been collected. This paper summarizes the design and practice of the general population cohort study in northeastern China to provide reference for related research in China.

Hyperuricemia is a chronic disease caused by the imbalance of uric acid synthesis and excretion, which is influenced by both environmental and genetic factors. The results of genome-wide association analysis related to hyperuricemia in different regions during the past decade have shown that genes related to hyperuricemia may be region- specific. This article summarizes the genes detected by GWAS, and describes some of the involved molecular mechanisms. The genes related to hyperuricemia shared by people in Europe, Asia, Africa and South America, and genes related to hyperuricemia unique to Asian populations are reviewed in this article. In addition, some of the genes’ functions are discussed to enhance the understanding of the pathogenesis of hyperuricemia.
