Objective To analyze the prevalence rate of diabetic nephropathy (DN) and the related factors on DN among type 2 diabetic patients.Methods A total number of 1758 type 2 diabetic patients who were hospitalized in the Beijing Hospital from 2003 to 2010 were analyzed retrospectively.Three groups were divided according to the rate of urinary albumin excretion (UAER).Patients whose UAER＜20 μg/min belonged to normal albuminuria (NA) group.The ones whose UAER from 20 to 200 μ g/min belonged to microalbuminuria (MA) group,and the others whose UAER≥200 μg/min belonged to large albuminuia (LA) group.The clinical characteristics were then compared.The related factors of DN were analyzed.Results (1)There were 1246 patients in NA group,408 patients in MA group,and 104 patients in LA group.The constituent ratio of nephropathy was 29.1％ (2) The ages of NA group,MA group and LA group were (59.87± 12.77,62.52± 12.74,64.44 ± 12.74) years old,respectively,with body mass index ( BMI ) as (24.90 ± 3.42,25.53 ± 4.00,25.53 ± 3.91 )kg/m2 respectively; duration of diabetes as (8.39 ± 7.12,10.77 ± 8.02,12.84 ± 7.97)years; systolic blood pressure (SBP) as (133.42 ± 18.19,142.72 ± 20.21,151.12 ± 21.91 )mm Hg;diastolic blood pressure as (78.75 ± 10.66,80.79 ±12.21,83.33 ±13.61 )mm Hg; fasting blood suger (FBS) as (8.25±3.43,9.02±3.72,9.22±4.62)mmol/L; glycated hemoglobin(HbAlc) as (8.88±2.10,9.34 ± 2.36,9.10 ± 2.36)％ ; uric acid (UA) as (288.04 ± 90.41,307.23 ± 96.96,374.28 ±105.47) mmol/L; triglyceride as (1.72 ± 1.51,2.06 ± 1.88,1.94 ± 1.42) mmol/L,high density lipoprotein cholesterol as ( 1.08 ± 0.30,1.02 ± 0.29,1.07 ± 0.28) mmol/L; fasting insulin as (9.24 ±9.02,11.24 ± 9.74,11.06 ± 9.29) μU/ml; fasting C peptide as (462.31 ± 289.94,510.02 ± 350.08,595.93 ± 445.86) pmol/L.There were significant differences between NA,MA and LA groups in all above items ( P ＜ 0.01 or P＜ 0.05 ).( 3 ) Logistic regression analysis showed that DN were related with duration of diabetes,BMI,SBP,HbAlc,FBS,UA (OR values were 1.041,1.055,1.028,1.116,1.100,1.004 respectively,P＜0.05 or P＜0.01 ).Conclusion It would be helpful to prevent and retard progression of DN that comprehensively controlling high blood glucose,hypertension,hyperuricemia and body weight of type 2 diabetic patients.

OBJECTIVETo evaluate the techniques and clinical applications of 16 multislice helical CT in colonic lesions.

METHODSEighty-one patients including 54 colorectal carcinomas, 5 adenomas, 1 non-Hodgkin's lymphoma, 6 inflammatory bowel diseases, and other 15 cases underwent volume scanning using 16 multislice helical CT. Four types of reconstruction included multiple planar reconstruction, shaded surface display, raysum, and CT virtual colonoscopy.

RESULTSComplete colon could be shown in all patients. The lesions' morphology, number, size, location, intestinal cavity, pericolonic changes, and other abdominal organs were satisfactorily shown by CT.

CONCLUSIONSSixteen multislice helical CT colonography is a valuable imaging technique for detecting colonic diseases. It is effective in diagnosis and treatment planning. It can display the portions of colon that is inaccessible at colonoscopy.

The G1 cytoplasmic tail of Hantaan virus (HTNV) harbors a highly conserved region, which is homologous to immunoreceptor tyrosine-based activation motifs (ITAM) and is termed the ITAM-like sequence. To demonstrate the potential signal-transducing activity of G1 ITAM-like sequence resembling the canonical ITAM within immune and endothelial cells, a series of experiments were performed to define its interaction with cellular kinases. The synthesized G1 ITAM-like peptide was shown to coprecipitate with cellular phosphoprotein complexes by an immune-complex kinase assay. Mutational analyses showed that this ITAM-like sequence was a substrate for the Src family kinase Fyn, and two conserved tyrosine residues were required for coprecipitating Lyn, Syk, and ZAP-70 kinases. These findings demonstrated that HTNV envelope glycoprotein G1 contains a functional ITAM-like sequence in its cytoplasmic tail, which can bind critical cellular kinases that regulate immune and endothelial cell functions.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.
