The fundamental mechanism of gastrointestinal diseases is the imbalance between the attack factor and the protective factor of stomach mucous membrane. It can not outbreak if the protective factor is stronger than the attack factor; otherwise, it will. Attack and protective function inside the stomach are mediated by various factors. These related factors interaction constitutes a complicated network system. This kind of outbreak theories of imbalance in Western medicine is same as that, "The sense of right saves inside, the evil can't do" and "Evil is competing with right, all diseases occur", in Chinese medicine. So, it is the key which points to futher study the interaction between gastrointestinal attack factors and protective factors by traditional Chinese medicine, thus improving the clinical effect.

Objective To analyze the correlation between polymorphisms at position 4 and 14 in exon 2 of the p73 gene and susceptibility to human papillomavirus (HPV) infection.Methods Tissue specimens were obtained from the lesions of 83 patients with condyloma acuminatum and 11 patients with bowenoid papulosis,and blood samples from all the patients as well as 150 health checkup examinees with high risk for sexually transmitted diseases (STDs) at STD clinics (negative control group).PCR was performed to detect HPV DNA in lesional tissue specimens,followed by direct sequencing and nucleotide alignment using the BLAST program for the determination of HPV genotypes.To assess polymorphisms at position 4 and 14 in exon 2 of the p73 gene,DNA was extracted from all the blood samples,and the p73 gene was amplified by PCR with the primer shP73 followed by gene sequencing.The association between the polymorphisms and susceptibility to HPV infection was analyzed.Results Of the 83 tissue specimens from patients with condyloma acuminatum,42.2％ (35/83) were positive for HPV 6,and 41.0％ (34/83) for HPV 11.Among the 11 tisssue specimens from bowenoid papulosis lesions,5 were positive for HPV 16,and 3 for HPV 6.The p73 gene was successfully amplified and sequenced from all the patients with condyloma acuminatum or bowenoid papulosis as well as from 132 out of 150 health checkup examinees.There were three genotypes at position 4 and 14 in exon 2 of the p73 gene,including A4T14/G4C14,A4T14/A4T14,G4C14/G4C14,of which,A4T14/A4T14 was associated with a higher risk for condyloma acuminatum (OR 4.89,95％ CI 1.50-15.91) as well as bowenoid papulosis (OR 7.11,95％ CI 1.144-44.20),and G4C14/G4C14 with a lower risk for bowenoid papulosis (OR 0.16,95％ CI0.04-0.65),in patients with HPV infection.Conclusions The A4T14 allele in exon 2 of the p73 gene increases the risk for bowenoid papulosis and condyloma acuminatum,but no significant correlation is found between the susceptibility to high-or low-risk HPV infection and polymorphisms at the two positions in the p73 gene.

AIM: To explore the effect of pyrrolidine dithiocarbamate (PDTC), an NF-κB inhibitor, on the proliferation and apoptosis of human multiple myeloma U266 cells and its mechanisms.METHODS: The U266 cells were treated with PDTC at different concentrations (0, 25, 50, 100 and 200 μmol/L) in vitro.The growth inhibitory rate of the U266 cells was detected by CCK-8 assay and cell counting.The cell cycle of the U266 cells was determined by flow cyto-metry, and the apoptosis was examined by flow cytometry with Annexin V-FITC/PI staining.The effect of PDTC on the expression of DNA methyltransferase 1 (DNMT1) at mRNA and protein levels was measured by RT-qPCR and Western blot, respectively.The effects of PDTC on the protein levels of NF-κB (P65), DNMT1, Bcl-2, cyclin D1, cleaved caspase-3 and cleaved caspase-8 were determined by Western blot.RESULTS: The protein level of NF-κB (P65) was decreased after treatment with PDTC for 48 h or 72 h.PDTC inhibited the proliferation of U266 cells in both dose-and time-dependent manners.After treatment with PDTC for 48 h, the percentage of U266 cells in G2 phase increased compared with control group (P<0.05).PDTC induced the apoptosis of U266 cells in a dose-dependent manner.The expression of DNMT1 at mRNA and protein levels decreased (P<0.05).The results of Western blot showed that the expression of Bcl-2 in PDTC groups decreased, while the protein levels of cyclin D1, cleaved caspase-3 and cleaved caspase-8 were higher than those in control group (P<0.05).CONCLUSION: The NF-κB inhibitor PDTC inhibits the proliferation of U266 cells by inducing cell apoptosis.It may be related to the down-regulated expression of DNMT1, cell cycle arrest and activation of the apoptotic pathways.

Objective To explore the prognostic value of biomarkers in type 2 diabetic patients with acute myocardial infarction (AMI), this study was to investigate the associations between the neutrophil to lymphocyte ratio (NLR), the Global Registry of Acute Coronary Events (GRACE) score and in-hospital mortality. MethodsSeven hundred and seven consecutive AMI patients were divided into diabetic group (DM-AMI group), impaired glucose tolerance group (IGT-AMI group), and normal glycemic group (NGT-AMI group). The laboratory and clinical characteristics were assessed retrospectively from the medical records. The NLR and GRACE score were calculated. Results In AMI patients, the DM-AMI group had significantly higher NLR and GRACE scores compared with those from the IGT-AMI group and NGT-AMI group (P<0.01 or P<0.05). In DM-AMI group, the NLR and GRACE score were considerably elevated in the elderly DM-AMI group compared with their younger counterparts (both P<0.01). Furthermore, the NLR was considerably higher in the high-risk group than those in both the low- and medium-risk groups based on the GRACE score (both P<0.01). The NLR was positively correlated with the GRACE score in DM-AMI group(r=0.425, P<0.01). The NLR level and GRACE score were higher in the death group than those in surviving patients (both P<0.01). The optimal cut-off levels of 9.36 for NLR and 166 for GRACE score seem to predicte death in-hospital. Based on the receiver operating characteristic curve, when to predict death in-hospital, the best cutoff value of NLR was 9.36 (sensitivity 80.8%, specificity 69.6%; area under curve 0.787), and the best cutoff value of GRACE score was 166 (sensitivity 76.9%, specificity 76.4%; area under curve 0.778). Conclusion An elevated NLR is a potential predictor of in-hospital mortality in type 2 diabetic patients with AMI, which could help clinicians indentify high-risk patients and determine appropriate treatment strategies. <英文关鍵词>>=Neutrophil to lymphocyte ratio; In-hospital mortality; Acute myocardial infarction; Diabetes mellitus, type 2

[Objective] To observe the effects of autophagy induced by different doses of ultraviolet B (UVB) irradiation on the apeptosis in human skin fibroblasts.[Methods] Skin fibroblasts were isolated from the circumcision specimen of a 23-year-old healthy male,and subjected to a primary culture.After 3 to 10 passages,the cells were collected and applied in the following experiment.Methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferation of some fibroblasts treated with different concentrations (0,0.5,2.0,5.0and 10.0 mmol/L) of 3-methyladenine (3-MA).To qualitatively and quantitatively detect the autophagy in fibroblasts treated with different concentrations of 3-MA and in fibroblasts treated with 3-MA of 0.5 mmol/Lfollowing UVB irradiation,monodansylcadaverine (MDC) staining was carried out,and immunofluorescence was used to detect the expression of microtubule-associated protein 1 light chain (LC3).Some fibroblasts were classified into 8 groups to remain untreated,be irradiated with UVB of 30,50 and 100 mJ/cm2 alone,treated with 3-MA of 0.5 mmol/L alone,or treated with 0.5 mmol/L 3-MA following irradiation with UVB of 30,50 and 100 mJ/cm2,respectively,then,cell apoptosis was qualitatively detected by Hoechst and propidium iodide (PI)staining,and quantitatively detected by flow cytometry with annexin V and PI.[Results] The percentage of autophagic cells was (63.037 ± 5.876) ％ in fibroblasts treated with starvation condition,significantly decreased to (34.425 ± 5.183) ％ in fibroblasts treated with 3-MA of 0.5 mmol/L.The expression of LC3 showed a gradually increasing trend from untreated fibroblasts,to fibroblasts irradiated with UVB of 30,50 and 100 mJ/cm2,while the increase was attenuated by the 4-hour treatment with 3-MA immediately after the irradiation.Compared with the other concentrations,the 3-MA of 0.5 mmol/L showed the least influence on the viability of fibroblasts.The addition of 3-MA of 0.5 mmol/L increased the percentage of cells both positive for Hoechst and PI staining in fibroblasts irradiated with UVB of 50 mJ/cm2,but decreased that in fibroblasts irradiated with UVB of 100 mJ/cm2.Similarly,the percentage of middle and late apoptotic cells was significantly higher in fibroblasts irradiated with UVB of 50 mJ/cm2 followed by treatment with 3-MA of 0.5 mmol/L than in those irradiated with UVB of 50 mJ/cm2alone ((10.933 ± 0.839) ％ vs.(7.267 ± 0.473) ％,t =5.20,P＜ 0.05),but lower in fibroblasts irradiated with UVB of 100 mJ/cm2 followed by treatment with 3-MA of 0.5 mmol/L than in those irradiated with UVB of 100 mJ/cm2alone ( (7.100 ± 0.781 ) ％ vs.( 1 0.133 ± 0.681 ) ％,t =6.29,P ＜ 0.05 ).[Conclusion]s The irradiation with UVB of 50 mJ/cm2 may protect fibroblasts by inducing autophagy and suppressing apoptosis,while the high level of autophagy induced by UVB of 100 mJ/cm2 may lead to autophagic cell death in fibroblasts.

OBJECTIVEThis study was conducted to observe dynamically the serum and stool level of IL-2, IL-6 and IFN-alpha with RV enteritis, and to analyse the relation of them and their relation to clinical manifestations.

METHODSThe double-antibody sandwich ELISA technique was applied.

RESULTSThe positive rate of RV in 119 enteritis cases was 63.0% and the peak month was November. These cytokines had different peak phases in the course of disease. The earliest cytokine which had peak phase was IFN-alpha, the last ones were serum and stool IL-2. There was a negative relation between stool IL-2 and IL-6 (P<0.01). There were positive relation between IL-2 and IFN-alpha, stool IL-6 and IFN-alpha, serum IL-2 and IL-6, stool IL-2 and the recovery time of the enteritis (P<0.01 or P<0.05). Serum and stool level of IL-2 and IFN-alpha had positive relation to the number of lymphocyte plus mononuclear cells (P<0.01 or P<0.05).

CONCLUSIONSIL-2, IL-6 and IFN-alpha play important roles of immunoregulation in RV enteritis, and have close relation to clinical manifestations.

OBJECTIVETo approach the role of tumor necrosis factor-alpha (TNF-alpha) and tumor necrosis factor receptor II (TNFR II) gene polymorphisms in genetic susceptibility to silicosis and their interaction with silica-dust exposure.

METHODSTwo hundred and fifty-nine cases of silicosis and three hundred and forty-one silica-dust exposure workers (control) were selected, and the cases of silicosis were divided into three subgroups based on the various stages of I, II and III. Exposure history, pneumoconiosis history and past history of each subject were obtained by questionnaire. 3 ml peripheral venous blood was drawn from each subject. Using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) techniques, TNF-alpha and TNFRII gene polymorphisms were analyzed.

RESULTSIn both group matching and 1:1 paired matching, there was no significant difference between cases of silicosis and workers in control in distribution frequencies of G/A + A/A (TNF-alpha-308) and T/G + G/G (TNFRII 196) genotypes. The risk of silicosis in those with G/A + A/A genotype was 6.74-fold higher than G/G genotype (OR = 6.74, 95% CI: 1.01 approximately 44.99) in subjects whose exposure time was less than 15 years.

CONCLUSIONTNF-alpha and TNFR II gene polymorphisms did not play an important role in susceptibility to silicosis of Han race. There was interaction between polymorphism of TNF-alpha gene promoter and exposure time in the occurrence of silicosis. The risk of silicosis in those with G/A + A/A genotype was significantly higher than G/G genotype in low accumulative exposure.
