Objective To explore the feasibility of detecting death-associated protein(DAP) kinase promoter hypermethylation in the tumor tissues and plasma of patients with gastric adenocarcino- ma,and to evaluate the effect of DNA hypermethylation and autofluroscene spectrums of gastric juice on diagnosing gastric carcinoma.Methods Primary tumor tissues and plasma and gastric juice of 50 patients with gastric adenocarcinoma were collected.Gastric mucosa tissue,plasma and gastric juice of 20 patients with chronic superficial gastritis and 20 patients with benign gastric ulcer and 30 patients with chronic atrophic gastritis were collected as controls.After sodium-bisulfite treatment,extracted DNA was amplified for DAP kinase promoter hypermethylation by methylation-specific polymerase chain reac- tion.At the same time the gastric juice autofluroscene spectrums(the excitation wavelength was 288 nm,whereas the range of emission wavelength was 300-800 nm)were detected.Results Among the samples from 50 patients,p16 and DAP kinase hypermethylation were detected in 74.4% and 68.1% of tumor tissues,52.0% and 58.0% of plasma,58.6% and 76.0% of gastric juice.No hypermethylation was detected in samples of chronic superficial gastritis and serum of patients with gastric ulcer.Among the patients with gastric ulcer,p16 and DAP kinase hypermethylation were detected in 10.0% and 20.0% of tissues,5.0% and 15.0% of gastric juice.Among the samples from 30 patients with chronic atrophic gastritis,p16 and DAP kinase were detected in 10.0% and 23.3% of tissues,3.3% and 3.3% of sera,3.3% and 20.0% of gastric juice.The intensity of gastric juice autofluroscence spectrums of patients with gastric carcinoma was much higher than those in controls.The sensitivity of p16 and DAP kinase hypermethylation and autofluorescence spectrums together were 95.6% and 97.8% respectively.Con- clusions Promoter hypermethylation of the p16 and DAP kinase gene detected in plasma and gastric juice consists with that in primary tumor tissues of patients with gastric adenocarcinoma.The combination of DNA hypermethylation and autofluorescence spectrum has a good future in diagnosing gastric carcinoma.

NDV strain ZJ1 strain , a highly virulent NDV strain, has been prevalent among the waterfowls in China mainland in the past years. Multi-basic amino acid sequence distribute in the protease cleavage site of F protein of this strain. Recombinant expressing plasmid pCI-FT, was generated by converting multi-basic amino acid sequence of 112, 115, 117 of the protease cleavage site of F_ 0 protein, to the non-basic amino acid sequence characteristic of avirulent NDV strain. The result from co-expression of mutant or parental F protein with homologous HN protein in COS-1 cells revealed that both mutant and parental F protein had fusion activity. The result from co-expression of mutant or parental F protein with homologous HN protein in CEF cells showed that the cleavage activity of mutant F protein was significantly reduced. The study built a foundation for mutagenesis of amino acid sequence of the protease cleavage site of F_ 0 protein at the full-length cDNA clone level, study on factors contributing to virulence and construction of candidate vaccine strain, and so on.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.

· AIM: To study the clinical characteristics of metastatic bacterial endophthalmitis.endophthalmitis were retrospectively studied.manifestation was found in 17 cases (77%), iridal purulent nodules in 2 cases and retinal purulent embolism In 3 cases. The total number of leucocytes and neutrophilic granulocytes was elevated markedly, while lymphocyte count was reduced significantly in early stage. Positive rate of bacterial cultivation was 36%.dophthalmitis often have apparent extraocular infected situation before eye Is involved. Ocular appearance and laboratory examination have some specificity in early stage, while bacterial cultivation, as a golden standard,needs to be further improved.

Eight fragments were amplified and cloned into pCR2.1 vector with the designed primers.The fragments,amplified with primer Ⅰ to Ⅶ,were subcloned into transcription vector to construct the plasmid pNDVZJI which contained the full-length cDNA of NDV ZJI strain.The eukaryotic expression vector pCI-L was constructed by subcloning the fragments,amplified with the primer Ⅴ,Ⅵ and Ⅷ,into the expression vector pCI-neo.The full-length cDNA clone,pNDVZJI,with three helper plasmids,pCI-NP、pCI-P and pCI-L,were cotranfected into BSR-T7/5 cell expressing T7 RNA polymerase.After inoculation of transfected cell culture into embryonated chicken eggs from specific pathogen free(SPF)flock,The NDV of ZJI strain was rescued successfully,which laid a good foundation for the further related research.

Objective To study the trend of accidental death among children under 5 years of age.Methods A survey on accidental death among children was performed in Guangzhou to compare the data from the national monitoring program on the deaths under five in the same period during 2001-2010.Data on mortality and causes of injures were adjusted by missing reports.Results Mortality rates on injuries were decreasing annually from 2001 to 2010.Comparing with 2001,the magnitude of the drop in mortality among the 0,1-4 and under 5 year groups were 72.02％,77.17％ and 74.66％ respectively,with statistically significant differences (P＝0.000).During the 10 years of observation,data showed a dropping trend (P＝0.000) of the mortalitics on drowning,traffic accident,suffocation and falling,especially on drowning and suffocation.The main causes of death were suffocation in the 0 year group,drowning in the 1-2-year group,traffic accident and poisoning in the 3-year group,traffic accident and falling in the 4-year group.The accidental deaths happened in ‘C area’ which including Huadu,Conghua,Zengcheng,Panyu and Nansha,with the total proportion of accidental death in Guangzhou as 75.69％.Conclusion The mortality of accidental deaths among children under 5 years of age in Guangzhou had been decreasing during 2001-2010,mainly owing to the practice of intervention programs on drowning and suffocation,suggesting the necessity of integrating the health education programs on accidental injury with the healthcare management system in children in the country,focusing on the suburban and county levels where economy was relatively undeveloped or with more floating population.

OBJECTIVETo assess the therapeutic efficacy and safety of Kunxian Capsule (KXC) in treatment of rheumatoid arthritis (RA).

METHODSRandomized positive parallel controlled and multi-center open test method was adopted. 240 RA patients of mild/moderate degree were randomly assigned to three groups equally, i.e., KXC group (who took KXC), the methotrexate (MTX) group (who took MTX), and the KXC + MTX group (who took KXC and MTX simultaneously), respectively. The therapeutic course for them all was 12 weeks. The effect of the treatment was assessed in items of DAS28, ACR20, and ACR50; number of joints with pain and swelling; VAS score of pain, tiredness, and general condition; time of morning stiffness; bilateral grip strength; HAQ score, as well as blood levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-CCP antibody, and platelet count.

RESULTSBy the end of the 4th week, the improvement of ACR20, ACR50, DAS28 efficacy judgment, and DAS28 score in the KXC + MTX group were much better than those in the other two groups, with statistical difference (P<0.05). The total effective rate was 88. 6% and the markedly effective rate was 51.8% in the KXC + MTX group at the 12 th week. The Improvement was more obviously shown in all groups after treatment (all P<0.05). Better effects in reducing VAS scores of pain and tiredness were shown in the KXC group and the KXC + MTX group. The effects of KXC + MTX were superior to the other two groups in terms of swollen joint numbers, pain joints, grip strength (assessed by researcher), as well as VAS score of general condition and HAQ score (assessed by both patients and researcher, P<0.05). But the differences among groups in improving morning stiffness and the incidence rate of adverse events were in- significant.

CONCLUSIONSKXC could relieve symptoms, improve joint functions, physical signs, and laboratory indices of RA patients with less adverse reaction. It was synergistic with MTX.

OBJECTIVETo evaluate the efficacy and safety of "Three-Typed Syndrome Differentiation" (TTSD) in treating type 2 diabetes mellitus patients.

METHODSA systematic review and meta-analysis was done based on the clinical diabetes treatment literature of the "TTSD". Overseas databases like the PubMed/MEDLINE, EMBASE, Cochrane Library and Cochrane Central Register of Controlled Clinical Trials, and China databases like China Biology Medicine Disc (CBM), Chinese national Knowledge Infrastructure (CNKI), Wanfang database, and VIP database, without limitation on language, were included with the time limitation from Jan 1982 to Dec 2012 by retrieval of relative original clinical research articles.

RESULTSNineteen articles where contains 1,840 diabetes patients were obtained, in which no adverse reactions were reported. Of these, 14 literatures involved the effect of fasting blood glucose (FBG), 10 involved that of postprandial 2-h blood glucose (P2hBG), and 19 involved the overall efficacy based on the national Chinese medicine (CM) diagnosis and treatment standard of diabetes. All the meta-analysis results prefer to the "TTSD" groups (CM+Western medicine Based on TTSD). The results show that, beside the efficacy of Western medicine, the concentrations of FBG and P2hBG in "TTSD" groups continue to drop with statistical significance. For "TTSD" groups, the FBG subsequently dropped 1.03 mmol/L, 95%CI [1.24,0.82] P <0.00001), the P2hBG subsequently dropped 1.09 mmol/L, 95% CI [1.61, 0.57] (P <0.0001), and the overall efficacies benefit 3.46 times those of Western medicine alone, 95% CI [2.67,4.48] (P <0.00001).

CONCLUSIONSThe CM by the diagnosis and treatment of type 2 diabetes based on TTSD might be safe and effective, and could better improve both blood glucose and the overall status of patients, including symptoms.
