Objective To explore the significance and correlation between MCP-1 and cardiovascular complication of diabetes. Methods 65 patients with diabetes and 64 patents with IGT and 60 healthy persons as control group are chosen from a population of 1231residents at Jiangnan community in Guangzhou city. Ultrasonic inspection of carotid artery was applied to the intimae media thickness (IMT),and the levels of-MCP-1 were detected by Elisa. Result There was significant difference in the levels of MCP-1 among the normal control group, IGT group and DM group (P=0.000).The levels of MCP-1 in IGT complicated with AS patients were significantly higher than that in IGT alone patients. The levels of MCP-1 in DM complicated with AS patients were significantly higher than that in DM alone patients. The levels of MCP-1 were positively correlated with IMT in these patients. A forward LR Logistic regression analysis showed that IMT was a dependent variable, gender, MCP-1 and age are independently correlated with IMT. Conclusion MCP-1 is correlated with diabetes and its cardiovascular complication and it may be served as the target of therapy.

Objective To summarize the value of early mechanical ventilation plus continuous vacuum suction in treatment of serious pulmonary contusion.Methods Forty-eight cases of severe pulmonary contusion were assigned to mechanical ventilation plus continuous vacuum suction (observation group,n =20) and mechanical ventilation plus discontinuous vacuum suction (control group,n =28)according to the random number table.Modes of mechanical ventilation were synchronized intermittent mandatory ventilation (SIMV),pressure support ventilation (PSV),and positive and expiratory pressure (PEEP).Changes in blood gas analysis,mechanical ventilation time,and associated complications were compared between groups.Results At ventilation time of 6 and 24 hours,PaO2 in observation group was (100.36 ± 5.90) mmHg and (105.34 ± 7.40) mmHg respectively,with significant differences from (75.36 ± 8.95) mmHg and (76.36 ± 8.35) mmHg in control group (P ＜ 0.01).At ventilation time of 24 hours,PaO2/FiO2 was (283.50 ± 15.20) mmHg in observation group and (201.50 ± 10.20) mmHg in control group (P ＜0.01).Mechanical ventilation time and PEEP at ventilation time of 48 hours in observation group was (3.2 ± 1.1) days and (4.5 ± 2.3) cmH2 O,with significant differences from (6.5 ± 2.8) days and (8.5 ± 2.5) cmH2O in control group (P ＜ 0.01).Associated complications of the two groups revealed no significant difference (P ＞ 0.05).Conclusion Early mechanical ventilation with sustained vacuum suction is effective to keep airway clear,improve oxygenation index,decrease PEEP level,and control the duration of mechanical ventilation,but may not lower the risks of ventilator-associated pneumonia and pulmonary atelectasis.

Objective To investigate the pharmacological mechanism of LXHX capsule. Methods The skin specimens from psoriasis patients were examined with TUNEL (terminal deoxynucleotidyl trans-ferase-mediated dUTP-biotin nick end labeling) technique to detect the apoptosis of keratinocytes. PCNA (proliferating cell nuclear antigen) detecting kits was used, too. Then, the flow cytometry, with AnnexinV/PI and PI dyeing method, was used to analysis the effect of LXHX capsule on apoptosis in cultured keratinocytes. Results There was an increasing of both cell apoptosis and proliferation in psoriatic epidermis and LXHX capsule could induce apoptosis. Conclusions The keratinocyte apoptosis and proliferation both increased in psoriasis, which reach a new balance in a higher level. LXHX capsule could induce apoptosis in vitro, which may be one of the pharmacological mechanisms of LXHX in treating psoriasis.

Objective: To prepare betahistine dihydrochloride sustained-release matrix tablets. Methods: The tablets were pre-pared with water soluble HPMC matrix, and the release behaviors were investigated by single factor study. The formula and preparation procedures were optimized by orthogonal design. Results:The optimal technology was as follows:using 60% HPMC K15M as the ma-trix material, calcium hydrogen phosphate as the filler, 10% PVP in 90% alcohol as the bonding agent;wet granulation compression technique was used to prepare the tablets with the tablet weight of 500mg. The in vitro drug release fits a Higuchi equation and the drug can be sustained-released within 12 h. Conclusion:The preparation technology is simple and the tablets have sustainol release behav-ior.

Objective To establish the three-dimensional model of pancreas and its surrounding structures.Methods The three-dimensional pancreas model was established and analyzed by using PC computer platform based on the data set from the first Chinese visible human female.Results The three-dimensional pancreas model,established successfully,could be rotated at any angles and could be sectioned at any orientation.The structures of each section could be displayed clearly.Conclusion Sectional anatomy at any orientation of the pancreas and its surrounding structures can be performed on our pancreas model,which has laid the foundation for virtual surgery of the pancreas.

Objective According to the data collected from gastric cancer families comparative study, the influence factors of Hardy-Weinberg (H-W) equilibrium in the association studies of gene polymorphism and disease were analyzed to reveal the reasons that affecting the equilibrium deviation in the group. Methods Varieties of risk genotype for gastric cancer were analyzed and detected with H-W equilibrium, genetic linkage disequilibrium analysis and Cochran-Armitage trend test. Results (1) Significant deviations from H-W equilibrium were observed in IL-1B-31, IL-IB-511, IL-IRN and TNF-A-308 of the cases and controls (P<0.01). MIF-173 tended to be equilibrium in the population. (2)Deviations from expectations of phenotypes combination probability were observed in two-site H-W χ2 tests (P< 0.01). (3)The Cochran-Armitage trend test showed that distribution of IL-1B-511 and IL-1RN were significantly different(P<0.05), suggesting that population stratification might have existed in the group. Conclusions (1)Affected by frequency-dependent selection, under the combination of linkage disequilibrium, mutations and interaction, genotype frequency of IL-1B-31, IL-1B-511, IL-1RN and TNF-A-308 showed deviation from H-W equilibrium in population. (2)Two-site genetic equilibrium test model seemed better to reflect the differences of phenotypic combination fitness. (3)Population stratification was another factor to express the deviation from H-W equilibrium.

Objective To build three-dimensional model of the pancreas and peripanercatic organs to provide morphological basis for imaging diagnosis and operation selection of pancreas diseases. Methods Serial cross-sectional images from the first Chinese visible human dataset were reviewed and the structures of pancreas and peripancreatic organs were reconstructed three-dimensionally by using 3D-Doctor software on PC. Results Three-dimensional structures of pancreas and peripancreatic organs were reconstructed successfully. All reconstructed structures could be displayed in multiple methods and color modes. Conclusions The internal and adjacent struc-tures of pancreas can be clearly shown on the reconstructed three-dimensional images. The visible model is a useful reference both for clinical diagnosis and surgical practice.

Four primers against the genes encoding(cpa,cpb,etx,and iA) four major toxins(?,?,?,?) of Cl. perfringens were designed and the colony multiplex PCR of identification and genotyping of Cl. perfringens strains were developed. Cl. perfringens reference strains stored in china institute of veterinary drug control including A,B,C,D and E genotyping were genotyped using the colony muitiplex PCR assay. The expected sequences were obtained successfully by the colony multiplex PCR assay. But the sequences were not obtained from Cl. novyi,Cl. septicum and Cl. tetani. The expected sequences were obtained from Cl. perfringens individual colony diluted to 100 times with 0.85% saline solution.13 Cl. perfringens strains isolated from diferent animals were genotyped using the colony multiplex PCR assay,and the results were comparaed with the results of toxins neutranization test in mice. The two assays showed good accordance. These results showed that the development of the colony multiplex PCR is very important for early and fast identification and genotyping of Cl. perfringens in china.
