ObjectiveTo investigate the clinical features of patients with primary biliary cirrhosis (PBC) in China. MethodsThe reported articles about clinical analysis of patients with PBC in China were searched. The quality of included studies was critically evaluated. Meta-analysis was performed using RevMan 4.2 software about controlled trials. Results① Ninety-one literatures including 2315 patients wuth PBC were included. ②The common symptoms in PBC were fatigue (54.54％). AMA was found in 74.1％～100％ of patients with PBC, as well as the prevalence rate of anti-M2 range from 45％ to 83％. ANA antibodies present in 20％～83.78％ of patients, the most common antinuclear patterns were nuclear-envelope(38.65％).Increased levels of IgM [(2.8±0.7)～(7.3±5.1) g/L], IgG [(16.5±4.9)～(20.5±5.9) g/L] were found in these patients, and the most common liver histologic classification was type Ⅱ (36.6％). Sjogren's syndrome occured significantly more frequently in PBC (1.96％～34.61％). To the end of follow-up period (five months to nintysix months ), 3.80％ of patients were dead. ③ Meta-analysis performed in several case control studies, showed no significant differences was found in liver tests including of alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotrans ferase (AST), total bilirubin (TBil), or gamma-glutamyltransferase (GGT), IgG levels between AMA positive groups and AMA negative groups. However, lower levels of IgM presented in the latter. While it also showed that levels of ALP decreased after ursodeoxycholic acid (UDCA)therapy. The levels of TBil were lower in the elderly than in younger group, but the mortality ratio for liver diseases was higher in the former. ConclusionThe clinical characteristics of the present series in China are mostly similar to those reported in other countries. Because of the low quality and the small number of included studies, larger sample-size, randomized, double-blinded controlled trials are needed.

Objective To observe the expressions of transforming growth factor-?1(TGF-?1) and plasminogen activator inhibitor-1(PAI-1) mRNA in tubulointerstitial fibrosis( TIF ) rats,and explore the effects of TGF-?1 and PAI-1 on TIF and the interaction between TGF-?1 and PAI-1.Methods Sixty male SD rats were randomly divided into sham operation group (SOR group,n=30) and unilateral urethral obstruction group(UUO group,n=30).TIF model was established via UUO.At d 7,d 14,d 21 after operation,10 rats of every group were killed to obtain renal samples.Histological changes were observed in tubulointerstitium injury under microscope;mRNA and proteins of TGF-?1 and PAI-1 were detected by real-time PCR assays and Western blotting respectively at d 7,d 14,d 21 after experiment onset.SPSS 10.0 software was used to analyze data.Results 1.HE,Masson staining of renal tissues of all groups indicated that there were no fibrosis in SOR rats,there were vacuole degeneration in tubular epithelial cells and inflammatory cell infiltration in tubulointerstitial in UUO rats at d 7,fibrosis aggravated gradually and became severe fibrosis at d 21.2.The expression locations of TGF-?1 and PAI-1 were renal sites of fibrosis by immunohistochemical staining.The mRNA and proteins of TGF-?1 in rats from SOR groups were lower than those of UUO groups at d 7,d 14,d 21(P

Objective To investigate the roles of myeloid differentiation factor 88 (MyD88) and TIR domain-containing adaptor inducing interferon-β (TRIF) in sepsis-induced myocardial dysfunction, and to analyze whether strain rate (SR) can be early sensitive evaluation for septic heart failure.Methods Sixty-four healthy male C57BL/6 mice were divided into four groups by random number table (n = 16 in each group): sham group, cecum ligation and puncture (CLP)-induced sepsis model group, anti-MyD88 group and anti-TRIF group. The anti-MyD88 group and anti-TRIF group were injected with 5μL/g of anti-MyD88 antibody or anti-TRIF antibody through the tail veins 2 hours before CLP. Eight animals in each group were used to observe the survival of 24 hours, and the other 8 myocardial tissues were harvested for examination. The cardiac function was evaluated by echocardiography before and 6 hours and 12 hours after operation. The mRNA expressions of MyD88, TRIF and inflammatory factors in myocardium were measured by polymerase chain reaction (PCR) at 24 hours after operation, and the degree of neutrophils infiltration was detected by myeloperoxidase (MPO) activity.Results The number of 24-hour survive in anti-MyD88 group and anti-TRIF group were higher than that in CLP group (number: 4, 3 vs. 2,P = 0.044,P = 0.047). Compared with sham group, the cardiac function was significantly decreased, the mRNA expressions of myocardial tissues MyD88, TRIF, interleukin (IL-1, IL-6) and tumor necrosis factor-α (TNF-α) were significantly increased, and the infiltration of neutrophils were obvious in CLP group. Compared with CLP group, the left ventricular short axis fractional shortening rate (FS) and SR were significantly increased after 12 hours in anti-MyD88 group and anti-TRIF group [FS: (49.52±1.78)%, (49.89±1.49)%vs. (41.11±1.63)%, SR (s-1): 17.63±2.16, 17.85±1.64 vs. 12.55±1.84]; the mRNA expressions of MyD88, TRIF and inflammatory factors were significantly decreased [MyD88 mRNA (A value): 0.463±0.046, 0.505±0.048 vs. 0.638±0.102, TRIF mRNA (A value): 0.413±0.031, 0.410±0.021 vs. 0.625±0.057, IL-1 mRNA (A value):0.569±0.101, 0.570±0.091 vs. 0.946±0.171, IL-6 mRNA (A value): 0.551±0.143, 0.431±0.157 vs. 0.850±0.194, TNF-α mRNA (A value): 0.471±0.082, 0.444±0.093 vs. 0.707±0.094]; and the infiltration of neutrophils were significantly decreased [MPO (U/L): 62.34±2.60, 60.87±2.40 vs. 73.83±4.90], with statistically significant differences (allP < 0.05). There was no statistical difference in above parameters between the anti-MyD88 group and anti-TRIF group (allP > 0.05).Conclusions Blocking MyD88 and TRIF expression play significant and similar roles in protecting cardiac deterioration from sepsis by attenuating cytokine release, reducing neutrophil infiltration. SR can sensitively assess septic cardiac dysfunction.

Objective The aim of this study was to explore the effect of androgen deficiency on serum hormone levels, visceral fat accumulation and inflammatory gene expression in miniature pigs fed a high-fat diet ( HFD) . Methods Sexually mature male Chinese Wuzhishan miniature pigs were divided into three groups ( animals/group) as follows:intact male pigs ( SHAM) , castrated male pigs ( CAS) and castrated male pigs plus testosterone treatment ( CAS+T) . The pigs were fed a HFD diet for 12 weeks. Serum levels of testosterone and leptin were measured and visceral fat were dissected and weighted. qRT?PCR was performed to determine the mRNA expression levels of lipogenic, lipolysis and inflammation relat?ed genes. Results (1) Serum testosterone levels were significantly decreased but serum leptin levels were significantly in?creased in the castrated pigs. These effects were recovered after testosterone treatment. ( 2 ) Visceral fat percentage was significantly increased in the castrated pigs, and testosterone treatment reduced the increased visceral fat in the castrated pigs. (3) Castration and testosterone treatment had no significant effects on the expression levels of lipogenic genes (FAS and ACC) and lipolysis genes (HSL and ATGL) in pigs fed a HFD. (5) Castration significantly induced the expressions of inflammatory genes including Leptin, CD68, CCL16, CCL23 and SAA, and testosterone treatment recovered the expres?sions of the above genes in the castrated pigs. Conclusions Castration?induced testosterone deficiency promotes visceral fat accumulation and upregulates the expression levels of inflammatory genes in miniature pigs fed a HFD. Moreover, tes?tosterone treatment ameliorates castration?induced visceral fat accumulation and inflammatory response in HFD?fed pigs.

Objective: To observe the effects of sodium heparin and low molecular weight heparin on the release of plasma hepatocyte growth factor (HGF) in senior coronary heart disease patients.Methods: Fifty-four senior patients with coronary heart disease were divided into three groups: intravenous sodium heparin, subcutaneous sodium heparin, and subcutaneous low molecular weight heparin (LMWH). Plasma HGF and vascular endothelial growth factor (VEGF) were measured before and after injection.Results: Plasma HGF was increased rapidly and significantly after intravenous injection of sodium heparin, reaching its peak level (about 48 fold) after approximately 10 minutes. Plasma HGF was also increased rapidly and significantly after subcutaneous injection of sodium heparin and LMWH, reaching its peak level (about 4 and 5 fold in sodium heparin and LMWH respectively) after approximately 2-3 hours. Conclusion: The rise of plasma HGF after heparin treatment suggests that heparin has some other biological effects in addition to its anticoagulant property through HGF. By this mechanism, the administration of heparin may be of some importance in the reparation of cardio-vascular diseases.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

Polycystic ovary syndrome(PCOS)is a common gynecological disease in clinic.Based on years of clinical practice,Professor ZHU Ling believes that the pathogenesis of PCOS is characterized by yang deficiency of kidney and spleen,and internal retention of phlegm and fluid,which accords with the pathogenesis nature of phlegm-retention.With reference to the pathogenic site of PCOS,PCOS can be allocated to the category of"phlegm-retention in uterus".Following the principle of"phlegm-retention resolved with warm herbs"established by ZHANG Zhong-Jing,Shenqi Pills plus Ling Gui Zhu Gan Decoction(aka,Shen Ling Decoction)recorded in Jin Gui Yao Lve(Synopsis of the Golden Chamber)can be used for the treatment of PCOS to warm yang and resolve phlegm-retention,dissolve phlegm and remove dampness,regulate menstruation and promote gestation,and significant efficacy can be achieved.The treatment of PCOS based on the principle of"phlegm-retention resolved with warm herbs"will provide a reference for clinical treatment of PCOS.

Objective:To remove murine embryonic stem cells(mESC)from the differentiating cell culture and purify the differentiated cells by Magnetic Activated Cell Sorting(MACS).Methods:Neural differentiation of mESC was induced by a 5-stage method.The specific cell surface marker,SSEA-1,was used to identify ES cells in the differentiating cells.The optimal dilutions of mouse anti mouse SSEA-1 IgM primary antibody and FITC conjugated goat anti mouse secondary antibody were determined before the flow cytometry test.The incubation time and incubation temperature of primary antibody were all optimized to make the cytometry test accurate.After the optimization,stage 4 cells were dissociated into single cell suspension,incubated with antibody of SSEA-1 and microbeads conjugated goat anti mouse IgM,and then sorted through the magnetic field.The rate of SSEA-1 positive cells in pre-and post-separation groups was assessed by flow cytometry,and the viability of cells was evaluated by trypan blue staining counting under light microscopy.Results:The proportion of SSEA-1 positive cells in the separated cells can be reduced from(7.19?1.36)% to(1.34?0.80)%.The survival rate of sorted cells was more than 92%,similar to that of pre-separation cells.Conclusions:The MACS system we used can effectively remove mESC from the differentiated cells.The sorted cells will be well provided for the subsequent studies about transplantation therapy.
