Objective To investigate the role of sonic hedgehog (Shh) signal transduction pathway in the expression of vascular endothelial growth factor (VEGF) under hypoxia in cultured human retinal pigment epithelial (hRPE) cells.Methods ARPE-19 were cultured and divided into normal ARPE-19 (Cont) and hypoxia group (100 μmol/L CoCl2 Cobalt Chloride +-ARPE-19);hypoxia group was further divided into CoCl2 group,cyclopamine group (CYA) and dimethyl sulfoxide (DMSO) group.20 μmol/L cyclopamine was added to the CYA group 1 hour before hypoxia,1‰ DMSO was added into DMSO group at the same time.The hRPE cells were cultured under hypoxia for 4,8,12,24 hours.The expression of Shh and VEGF were determined by Real-time fluorescent quantitate PCR (RT-PCR).The amount of VEGF in the hRPE-conditioned supernatant was measured using enzyme linked immunosorbent assay (ELISA) at 4,8,12,24 hours,respectively.Results RT-PCR tests showed that the level of Shh and VEGF of hRPE was time dependently increased (Shh:F=45.260,P=0.001;VEGF:F=264.938,P=0.001).The level of Shh and VEGF of hRPE in the group treated with cyclopamine was decreased (P＜0.01).ELISA tests showed that the amount of VEGF in hRPE supernatant was significantly increased in time-dependent manner (F =3 156.676,P =0.001),and it was down-regulated by cyclopamine under hypoxia (P＜0.01).Conclusion Shh signal transduction pathway could play a role in the VEGF expression induced by hypoxia in hRPE cells.

Objective To detect the expression of SSX and to correlate it with clinical indicators of primary hepatocellular carcinoma (HCC).Methods The expression of SSX1-5 mRNA and SSX1 protein were respectively detected by RT-PCR and Western blot and immunohistochemistry staining.The relation between the expression of SSX mRNA and SSX1 protein with clinical indicators were analysed.Results SSX1,SSX2,and SSX3 mRNA were expressed in hepatocellular carcinoma cell lines BEL-7404,Hep G2,and SMMC-7721.In 26 HCC samples,SSX1-SSX5 mRNA was detectable in 53.8％,42.3％,50.0％,46.2％ and 26.9％.The expression of SSX1 mRNA was not related to serum AFP levels (P ＞0.05).Specific expression was both found in the normal group and the high value group.The expression rate of SSX1 mRNA was 85.7％ in the older group,which was higher than in the younger group (16.7％,P ＜ 0.05).The expression rate of SSX1 protein was 50％ in HCC tissues,which was not seen in the caner-adjacent or cirrhosis tissues.In 49 HCC paraffin tissue section samples,the expression rate of SSX1 protein was higher than that in caner-adjacent tissues (46.9％ vs 18.4％,P ＜ 0.05).The expression rate of SSX1 protein was 68.3％ in the large hepatocellular carcinoma group,which was higher than in the small hepatocellular carcinoma group (29.6％),(P ＜ 0.05).Conclusions SSX1 mRNA is expressed with a high percentage and specificity in HCC and their products are new potential promising targets for antigen-specific immunotherapy of HCC.The detection of SSX1 expression has the potential value for auxiliary diagnosis of HCC.

The stage of impaired glucose regulation is a necessary stage in the development of diabetes.Nearly a quarter of patients without diabetes intervention develop into diabetes within four to seven years without intervention.Therefore,the intervention of pre-diabetes treatment in the prevention and control of diabetes is of great significance.This study was to investigate the effect of Tangnaikang granule at the early stage of type 2 diabetes mellitus.The age,course of disease,sex,symptom score of TCM were recorded,so were the blood lipid,blood glucose,liver and kidney function,electrocardiogram were recorded.Under the condition of low sugar and low salt diet and healthy exercise,the patients were divided into the control group (n--31) and the treatment group (n=43).The patients in the double-blind control group were treated with Kangnaikang granule and Tangnaikang granule to treat 74 patients with type 2 diabetes mellitus three months.Three months after the detection of fasting and postprandial blood glucose,glycosylated hemoglobin,glucose tolerance,insulin tolerance and other indicators to examine the efficacy of both.Tangnaikang granules were superior to placebo in terms of effective rate of treatment,TCM symptom score and blood sugar recovery rate,and taking Tangnaikang granule without liver and kidney function and other injuries.Tangnaikang is safe and effective for pre-diabetes patients.

Objective To evaluate the protective effect of polysaccharide nucleic acid fraction of bacillus Calmette-Guerin (BCG-PSN) against atopic dermatitis (AD) in Nc/Nga mice,and to explore its possible mechanism.Methods Sixteen Nc/Nga mice were classified into normal control group (n =4),low-concentration BCG-PSN group (n=5) and high-concentration BCG-PSN group (n =7) to be subcutaneously injected with sodium chloride physiological solution,BCG-PSN of 0.1 mg/kg and 0.5 mg/kg respectively,at 1,8,15 and 22 days of age.Dinitrochlorobenzene (DNCB) was repeatedly and topically applied to these Nc/Nga mice to induce AD-like lesions at 49 days of age.The preventive effect of BCG-PSN against AD was evaluated by dermatitis scores,scratching frequency,histopathological manifestations and immunological parameters (including IgE,i nterleukin (IL)-4 and-12,and interferon (IFN)-γ).Results Repeated injection of BCG-PSN within 4 weeks after birth significantly decreased the severity of DNCB-induced AD-like lesions,dermatitis scores and scratching behavior in Nc/Nga mice.There was no statistical difference in scratching frequency between the high-and low-concentration BCG-PSN groups.BCG-PSN treatment reduced the plasma level of IgE in Nc/Nga mice in a dose-dependent manner.BCG-PSN at 0.5 mg/kg increased the number of cells secreting IFN-γ in skin lesions of mice.Both doses of BCG-PSN down-regulated IL-4 level,but up-regulated IL-12 level in the culture supernatant of spleen mononuclear cells from mice.Conclusion Early injection of BCG-PSN could protect Nc/Nga mice against dermatitis by promoting the proliferation of IFN-γ-secreting cells,increasing the synthesis of IL-12,and reducing the levels of IL-4 and IgE.

BACKGROUND:Pulmonary aspergilosis is a disease caused by pulmonary fungal infection. Its diagnosis and treatment is usualy delayed because of nonspecific clinical symptoms, physicial sign and imaging changes as wel as uncertainties of histological and bacterial findings. Therefore, it is necessary to establish mouse models of invasive pulmonary aspergilosis to investigate the underlying pathological mechanism and novel therapeutic methods. OBJECTIVE: To establish mouse models of invasive pulmonary aspergilosis, detect the expression ofγ-interferon, Tol-like receptor 2 and Tol-like receptor 4, and discuss the mechanism of action underlying invasive pulmonary aspergilosis. METHODS:Seventy-five female BALB/c mice of clean grade, aged 6-8 weeks, were randomly and evenly divided into five groups: blank control group (group A), immunosuppressive model group treated with high concentrations of Aspergilus fumigatus spore suspension (group B), normal infection group treated with high concentration of Aspergilus fumigatus spore suspension (group C), immunosuppressive model group treated with low concentration of Aspergilus fumigatus spore suspension (group D), normal infection group treated with low concentration of Aspergilus fumigatus spore suspension (group E). First, mice in the groups B and D were intraperitonealy injected with cyclophosphamide to establish immunosuppressive models. The mice in the groups D, E (108 cfu/mL) and groups B, C (109 cfu/mL) were treated with 12 mL Aspergilus fumigatus spore suspension through the use of nebulizer. Mice in the group A were treated identicaly with sterile PBS. At 1, 3, 5 days of infection, the pathological change of lung tissue was observed, the mass concentration of γ-interferon in bronchoalveolar lavage fluid and the expression levels of γ-interferon mRNA and Tol-like receptor 2 and Tol-like receptor 4 mRNA and protein in the lung tissue were determined. RESULTS AND CONCLUSION:Abscess, spores and very severe bleeding and congestion, widenened alveolar septum and tracheal epithelial cel shedding and necrosis were observed in the mouse lung tissue in the group B. At 5 days of infection, the mass concentration of γ-interferon in bronchoalveolar lavage fluid and the expression ofγ-interferon mRNA in the lung tissue in the group B were significantly decreased compared with the group A (P < 0.05). Tol-like receptor 2 expression was strongly positive in the group B. Tol-like receptor 2 expression in the group C was significantly lower than that in the group B (P< 0.05). Tol-like receptor 4 expression was positive in the groups B and C, and its expression in the group C was significantly greater than in the group B (P < 0.05). The expression of Tol-like receptor 2, 4 mRNA in the mouse lung tissue of group B was significantly increased at 1, 3, 5 days of infection (P < 0.05). These results suggest that atomizing high concentration of aspergilus fumigatus spore suspension to immunosuppressive mice can establish stable invasive pulmonary aspergilosis models with typical pathological features. The infection of aspergilus fumigatus can activate tol-like receptor 2, 4 at the same time, and the pathological mechanism is closely related to organism’s immune defense function.

Ahigh-resolutionmethodforhumanleukocyteantigen-B(HLA-B)genotypingwasestablished based on the optimized polymerase chain reaction, cloning and sequencing technology. The exon2 and exon3 of HLA-B gene were amplified with primers based on the HLA-B gene sequence. These produced heterozygous alleles were effectively cloned into plasmid DNA based on the principle of plasmid incompatibility, and were followed by bacterial culture. Then Sanger sequencing was carried out and after analyzing the result by software ClustalX2 and IMTG/HLA database comparison, the HLA-B genotype of the samples was achieved. Seven clinical samples were detected, and the results were consistent with those of PCR-SBT genotyping method. The method was cost-effective, high-resolution and it did not require technical software. The use of universal primers simplified the cumbersome design and optimization process of specific primers.
