Objective To study the reliability of clinic diagnosis of hepatitis B virus(HBV)-associated glomerulonephritis.Met- hods Renal biopsy was carded out in 103 cases with clinically-diagnosed HBV-associated glomerulonephritis. The diagnostic consistency and clinical difference were evaluated.Results Sixty nine cases with clinically-diagnosed HBV-associated glomerulonephritis were confirmed through renal biopsy, 29 cases were excluded from HBV-associated glomerulonephritis. The pathologic diagnosis and clinical diagnosis methods were highly correlated and has significant difference(P

Thoracic aortic dissection was a catastrophic disease with change quickly,and the characteristic of thoracic aortic dissection was acute onset,complex,progress rapidly,difficult to diagnosis,and highly misdiagnosis rate.So the fatality rate of thoracic aortic dissection was high,which easy caused medical disputes.Even so,the cause of the formation of thoracic aortic dissection in detail is not clear,and many risk factors associated with the occurrence of thoracic aortic dissection.These including high blood pressure,gender (male),aortic normal aging,drug using,atherosclerosis,genetic disease and inflammatory diseases,etc.

Objective To study on the changes of the IL-6、IL-8、TNF-? in the type 2 diabetes with insulin resistance and the relation of plasma glucose or insulin resistance and cytokines. Methods (1) To assay the serum level of cytokines in 90 cases with type 2 diabetes mellitus (T2DM) and 30 normal controls. (2)To measure the level of fasting plasma glucose (FPG),hemoglohin A_1c (HBA_1c),fasting insulin(FINS),fasting C-peptide (FCP).(3) To analysis the relation of the level of FPG,HBA_1c,FINS,FCP and cytokines. Results (1) The serum levels of cytokines in T2DM group were significantly increase than in control groups,IL-6 and TNF-? in T2DM group with insulin resistance were significantly increase than in T2DM group without insulin resistance (2) There was significantly positively correlated between insulin resistance and the increasing of cytokine levels. Conclusion There is an excess activation of cytokines in T2DM,which is significantly correlated with insulin resistance. Cytokines play the important role in the occurrence and development of T2DM and insulin resistance.

Objective To investigate the extracellular regulated protein kinases (ERKs) pathway of hepatitis B virus(HBV) X protein(HBx) on glomerular mesangial cell(GMC) proliferation of rat and tumor necrosis factor(TNF)-? expression.Methods The HBV X gene was amplified by polymerase chain reaction(PCR),inserted into the eukaryotic expression vector PCI-neo and confirmed by restrict endonuclease digestion and sequence analysis.PCI-neo contained HBV X gene (PCI-neo-X) was transfected into cultured GMC via liposome.GMC proliferation,TNF-? and its mRNA expression were investigated in the condition of with or without U0126 in the culture media.HBx,ERK1/2 and phosphorynated-ERK1/2 (p-ERK1/2) expression in GMC were assessed by Western blot.TNF-? mRNA expression was assessed by semi-quantitative reverse transcriptase-PCR (RT-PCR).TNF-? level in supernatants was measured by enzymelinked immunosorbent assay(ELISA).GMC proliferation was assessed by methyl thiazolyl tetrazolium(MTT).Results HBx expression was found in transfected GMC,and became prominent at 36 and 48 hours after transfection whether with or without U0126 in culture media.TNF-? mRNA expression was significantly decreased in U0126 group compared with U0126-free group.TNF-? levels in supernatants in PCI-neo-X transfection without U0126 group were (189.0?18.1) ng/L at 36 hours and (172.3?24.3) ng/L at 48 hours after transfection,respectively.In contrast,TNF-? levels in supernatants with U0126 were (65.6?11.6) ng/L and (84.0?24.6) ng/L,respectively.The TNF-? le-vels in the latter groups were significantly lower than the formers (Pa

Objective To investigate the value of multi-slice CT in diagnosis of abdominal cocoon.Methods CT findings of six cases with pathologically proved abdominal cocoon were collected and analyzed retrospectively.The three-dimensional imagines were obtained including multi-planar reconstruction(MPR),maximum intensity projection(MIP)and volume rendering(VR)at workstation,the rela-tionships between the lesions and surrounding structure were observed.Results A group of local small intestine were seen gathered in all six cases,the coiled intestine arranged inaccordionshape orbananashape.The fibrous capsule were seen around them with different thickness,which were low density and slightly enhancement.Mesenteric arteries showed abnormal changes,showing ten-sion,aggregation.Conclusion MSCT can provide a wealth of diagnostic information and is the best method of examination abdomi-nal cocoon.

Objective To explore the relationship between quality life and TCM constitutions of elderly patients with hypertension in a community in Shanghai; To provide the basis for the suitable and feasible community elderly hypertension management method. Methods Through multistage stratified sampling method, 808 elderly patients with hypertension in the community were investigated for their life quality and TCM constitutions on the basis of inform consent and voluntary participation. The life quality and TCM constitution characteristics as well as the relationship were analyzed by applying the statistic analysis software. Results Among the investigated elderly patients with hypertension in the community, 97.28% cases’ overall life quality was above the middle level and 91.46% cases’ self-evaluated health and quality of life scores were above the middle level. 54.70% cases were gentleness type, and the biased constitution was dominated by qi deficiency, yang asthenia, yin asthenia and phlegmatic hygrosis. The relationship between life quality and TCM constitutions may be existent. If TCM constitutions tended to be gentleness type, the physical score and the psychological score would be higher, which leaded to better quality of life. Conclusion TCM constitution characteristics are associated with quality life of elderly hypertension patients in the community. Intervention targeted on the results of TCM constitution identification would be better to prevent and control hypertension and improve health level and quality of life.
