By clinical observing and summarizing a large amount of data, we found that the regularity of tongue presentation in stroke patient has important clinical significance. In the acute stage, the tongue coating and body of tongue should be observed carefully to tell the seriousness and the tendency of a disease; in the stable stage, the tongue coating and the texture of tongue should be observed carefully to tell progress of diseases; and in the recovery stage the texture of tongue should be observed carefully to judge the changes of Qi and Xue in viscera and prevent the relapse prevention of disease.

Objective:To explore the relationship between eosinophil(EOS) and IL-5,sIL-2R in asthmatic patients in sputum. Methods:Thirty asthmatic patients (asthmatic group) during exacerbation and stable stage and twenty healthy persons were selected.IL-5 and sIL-2R in sputum were determined by ELISA ,EOS apoptosis was identified by flow cytometre.Results:IL-5 ,sIL-2R and EOS apoptosis percentages in the patients during exacerbation and stable stage in sputum were increased significantly,.There were no expression of EOS apoptosis in the healthy persons. Data analyses revealed a negative correlation between EOS apoptosis and the levels of IL-5, and a closer correlation between the percentages and IL-5.Conclusion:EOS underwent apoptosis in asthmatic airway and EOS apoptosis was regulated by IL-5.There were no correlation between EOS apoptosis and sIL-2R.

Objective To investigate the effect of influenza virus on the expression of collagen triple he-lix repeat containing 1 (CTHRC1). Methods A549 cells were infected with influenza virus. mRNA and protein levels of CTHRC1 were determined by RT-PCR and Western blot , CTHRC1 levels in the cell supernatants and sera of influenza virus infected patients were determined by enzyme-linked immunosorbent assay (ELISA). The difference of CTHRC1 levels between healthy controls and HCV patients was analyzed. Results Compared with controls, mRNA and protein levels of CTHRC1 were higher in A549 cells infected with H3N2. Serum CTHRC1 levels were higher in influenza virus infected patients than in healthy controls (P < 0.05). Conclusion Influenza virus can promote the synthesis and secretion of CTHRC1.

Objective To observe the effects of color retention treatment on the preservation of medicinal plant herbariums, film-cover specimens and resin specimens. Methods Seven kinds of medicinal plants with different characters after color retention treatment were made into herbariums, film-cover specimens and resin specimens, and then the preservation results for the above three kinds of medicinal plant specimens with or without color retention treatment were compared. Results Resin and film-cover specimens without color retention treatment had better preservation results than herbariums. All of the three kinds of specimens with color retention treatment had better preservation results for the original color and shape than the specimens without color retention treatment. Conclusion Color retention treatment for the medicinal plants results into higher preservation quality of the herbariums and longer preservation period.

Objective To analyze the plasma free fatty acid (FFA) composition in patients with T2DM. Methods All subjects were from Zhongnan hospital of Wuhan university, and they were divided into three groups: normal control ( n = 94 ), T2DM ( n = 101 ) and T2DM with hyperlipidemia ( n = 77 ). Fasting blood samples were taken from the participants, and plasma FFA were separated using a modified Doles method with the bromoacetophenone, pre-column-derivative. The quantitation of FFA was performed on were (355.63 ± 100. 35) μmol/L, (421.21 ± 200. 83 ) μ mol/L, ( 473.04 ± 213.40 ) μmol/L in healthy controls, T2DM group and T2DM with hyperlipidemia group, respectively. The significant differences were observed among the 3 groups(x2 = 13.08, P <0.01 ). However, there was no significant difference of UFA concentrations among the 3 groups [(206.29± 61.94) μ mol/L, (218.11 ± 110.28) μmol/L and ( 240.94 ± 116.79 ) μmol/L, x2 = 2.17, P > 0.05]. Compared to normal control [( 355.63 ± 100.35 )μmol/L], the FFA concentration[(421.21 ±200.83) μmol/L] in T2DM has significantly increased (x2 =FFA concentrations were higher in T2DM with hyperlipidemia [(473.04 ±213.40) μmol/L] (x2 =27.93,P <0.01 ). The RSD values for intra- and inter-day precision were less than 5%, and the minimal detection limits ranged from 0.05 μmol/L to 0.35 μmol/L The recoveries of high, intermediate and low-level materials were 96.4% -104.8%. Conclusions The total FFA concentration in T2DM has increased, most of which are saturated FFA. The unsaturated FFA has not significantly increased. They seem to be related to the development of T2DM, and might be a new biomarker for clinical monitoring of metabolic disorder of T2DM.

OBJECTIVE To study the isolation,distributive characteristics and drug resistance of AmpC enzyme producing Gram-negative bacilli in nosocomial infection of two years and provide the evidence for treatment. METHODS A total of 528 strains of Gram-negative bacilli collected from daily specimens were identified with Bio-Fosun-Ⅰ,and AmpC enzyme was screened by cefoxitin disk and then corroborated by EDTA disk method. All data were analyzed statistically. RESULTS Among 528 strains collected,136 (25.75%) were AmpC enzyme producing strains,the respective percentage of Pseudomonas aerugionsa,Echerichia coli,Enterobacter cloacae,Klebsiella pneumoniae and Citrobacter was 32.35%,28.67%,18.38%,8.09% and 5.15%,respectively. Most strains (38.9%) were detected in ICU. The common infection sites were lungs. The resistance rate of AmpC enzyme producing strains to the first,second and third-generations cephalosporins was 71.3-99.5%. The susceptive rate of AmpC enzyme producing strains to imipenem,cefepine,amikacin and piperacillin/tazobactant were low. CONCLUSIONS For effective supervision and control of AmpC enzyme producing Gram-negative bacilli in nosocomial infection,detection of AmpC enzyme shoud be paid much attention by clinical microbiology laboratory.

Emerging evidence has indicated that BRCC 36-mediated K63-linked ubiquitination modification was involved in diverse cellular functions , including endocytosis , apoptosis and DNA damage repair .We previously showed that activation of cGMP/PKG pathway con-tributed to the binding of BRCC36 and the pro-fibrotic factor Smad3.The current study tested the hypothesis that BRCC 36 functions as a negative regulator of transforming growth factor-beta ( TGF-β)/Smad3 pathway and participates in cardiac remodeling .In isolated adult mouse cardiac fibroblasts , we have demonstrated that TGF-β1 treatment significantly increased the expression of BRCC 36.Over-expression BRCC36 suppressed TGF-β1-induced Smad3 phosphorylation, nuclear translocation, extracellular matrix molecular expres-sion and cell proliferation .On the contrary, silencing BRCC36 by transfection of adenovirus-carrying BRCC36 shRNA potentiated to
enhance the pro-fibrotic effect of TGF-β.In vivo, under chronic pressure overload condition-induced by transverse aortic constriction , myocardial pro-survival protein Bcl-2 and Mcl-1 expression were significantly decreased and the pro-apoptosis protein Puma was in-creased.However, the cardiac-specific over-expression of BRCC36 significantly increased myocardial Bcl-2 and Mcl-1 and inhibited Puma expression .Interestingly , we also found that sustained pressure overload resulted in a significant myocardial DNA injury in wild type mice, which was characterized by the increase of γH2AX level.However, cardiac-specific BRCC36 over-expression significantly decreased the level of γH2AX in the pressure overloaded heart in the transgenic mice , while effectively enhanced myocardial RAD 51 expression, a marker of DNA damage repair.Furthermore, BRCC36 over-expression effectively attenuated TAC-induced cardiac fibro-sis and remodeling in the transgenic mice , compared with the wild type mice .Collectively , the results have suggested that BRCC 36 ef-fectively protected heart against chronic pressure overload-induced cardiac remodeling though antagonizing TGF-β/Smad3 pathway and enhancing myocardial DNA injury repair response .

The root and stem of this plant is a folk medicine known to have the actions of relieving rheumatism and cold and subsiding swelling and pains. To investigate the chemical constituents in the root of A. polymorpha Maxim., seven compounds were isolated from an 80% ethanol extract by column chromatography. Their structures were elucidated according to the spectroscopic analysis. Compound 1 is a new sesquiterpene, named as bisabolactone. Its absolute configuration was determined by 1D NOESY and CD analysis. The others were identified as 5-hydroxymethylfurfural (2), hycandinic acid ester 1 (3), ferulic acid (4), isooxypeucedanin (5), noreugenin (6) and cimifugin (7). Compound 2 and 3 were isolated from this genus for the first time and compound 4 was isolated from this plant for the first time.

Objective To investigate the effects of erythropoietin (EPO) on complement 3a (C3a)-induced renal tubular epithelial to mesenchymal transition. Methods The HK-2 cells were divided into 6 groups namely control group,EPO group,TGF-β group,TGF-β+EPO group,C3a group and EPO+C3a group.The mRNA and protein expressions of α-SMA,E-cadherin and C3 were investigated by RT-PCR,Western blot and immunofluorescence respectively. Results Compared with control group and EPO group,the mRNA and protein expressions of α-SMA in HK-2 cells were up-regulated after the intervention of C3a or TGF-β (all P＜0.05).On the contrast,the mRNA and protein expressions of E-cadherin were down-regulated(P＜0.05),the mRNA and protein expressions of C3 were enhanced (all P＜0.05).However,all those above effects of C3a or TGF-β were inhibited after the intervention of EPO (all P＜0.05). Conclusion EPO is capable of suppressing the epithelial to mesenchymal transition induced by C3a.

Purpose To describe clinicopathological features, diagnosis and differential diagnosis of Castleman′s disease. Methods Retrospective analyses of the clinical data, clinicopathology and immunohistochemistry were conducted in ten cases of Castleman dis-ease and reviewed of literature. Results There were 8 cases of unicenrtic Castleman′s disease and 2 cases of multicentric Castleman′s disease. Pathologically, there were 6 cases of hayline vascular types, one case of plasmatcyic type and 3 cases of mixed type in all Castleman′s disease. Immunohistochemically, all cases were negative for BCL-6 and CD10, and Ki-67 expression was less than or e-qual to 30%. There were 4 cases with complete follow-up data, including one case of intermediate type, 3 cases of hyaline vascular type which were healed by surgical resection without recurrence. Conclusions Castleman′s disease is a rare and lymphoproliferative disorders with unknown cause, it is not easy to diagnose before the operation. Whether immunohistochemical features reflect abnormal immune function or play unknown role in the pathogenesis of Castleman′s disease is also demanded further study.
