Objective To investigate the relationship between sonic hedgehog(SHH)signaling pathway and chronic pancreatitis.Methods Thirty Wistar rats were randomly divided into the model group,experimental control group and blank control group,and there were 10 rats in each group.Trinitrobenzene sulfonic acid was infused into the pancreatic duct of the rats to induce pancreatitis in the model group.The pancreatic duct of the rats in the experimental control group were infused with 0.9％ sodium chloride solution.No treatment was performed on rats in the blank control group.The serum levels of bilirubin and amylase of the 3 groups were determined,and the histopathological alterations were studied.Expressions of patched-1(PTCH-1),smoothened (SMO)and SHH were detected by immunohistochemistry.All data were analyzed using the analysis of variance or Student's t test.Results The levels of total bilirubin(TBil)in the model group,experimental control group and blank control group from day 1 to day 35 were(3.17 ±0.21)μmol/L-(9.28 ±2.15)μmol/L,(3.44 ±0.54)μmol/L-(3.76 ± 0.15)μmol/L,(2.45 ± 0.32)μmol/L-(3.27 ± 1.43)μmol/L,respectively.The levels of amylase in the model group,experimental control group and blank control group were(1124 ± 143)U/L-(1522 ± 169)U/L,(1123 ± 104)U/L-(1007 ± 141)U/L,(1014 ± 115)U/L-(1013 ± 142)U/L,respectively.Compared with the experimental group and the blank control group,the serum levels of TBil and amylase in the model group were increased significantly from day 7 to day 35(F =14.81,16.27,18.13,11.49,17.91;11.54,10.24,12.64,21.11,15.38,P ＜ 0.05),and fibrotic proliferation of pancreatic tissues were found at day 35;the expressions of PTCH-1,SMO and SHH in the pancreatic tissue was increased significantly in the model group.Conclusion SHH signaling pathway is activated in the tissue of pancreatitis in rats,it might play an important role in the genesis of pancreatitis.

BACKGROUND: The feasibility and the mechanism of human umbilical cord blood mesenchymal stem cel transplantation for the treatment of liver cirrhosis need to be discussed in-depth. OBJECTIVE: To observe the effect of human umbilical cord blood mesenchymal stem cel transplantation through portal vein on the liver function and tissue pathological changes of the rats with liver cirrhosis. METHODS: Carbon tetrachloride was used to prepare rat model of liver cirrhosis. After the success of modeling, the rats in the cel transplantation group received portal vein injection of 1 mL 5-bromo-2-deoxyuridine -labeled human umbilical cord blood mesenchymal stem cells (5×106), the model group was injected with the same volume of PBS; the normal rats received 1 mL human umbilical cord blood mesenchymal stem cel transplantation via the portal vein were as the control group. At 4 weeks after transplantation, the rat tail vein blood and liver tissue were obtained for testing. RESULTS AND CONCLUSION: At 4 weeks after cel transplantation, compared with the model group, levels of serum alanine aminotransferase, aspartate aminotransferase and total bilirubin in the cel transplantation group were significantly decreased, while the albumin level was increased significantly (P < 0.01); the liver cel inflammatory necrosis, steatosis and liver fibrosis were improved significantly (P < 0.05 or P < 0.01). Immunohistochemistry and immunofluorescence staining showed that human umbilical cord blood mesenchymal stem cel colonization could be seen in the rat liver tissues of the cel transplantation group and control group, but the number of 5-bromo-2-deoxyuridine-positive cells in cel transplantation group was significantly larger than that in the control group. Reverse transcription-PCR test result showed that the expressions of cytokeratin 18 and albumin mRNA could be observed in the rat liver tissue of the cel transplantation group, but no expression could be seen in the control group. It is visible that human umbilical cord mesenchymal stem cells can improve liver function and pathological damage of liver cirrhosis rats in a certain extent, which may relate with the intrahepatic homing colonization and hepatocyte-like cel differentiation of the transplanted cells in the liver cirrhosis rats.

Thyrotropin releasing hormone (TRH) and naloxone were compared in their antagonism to the effects of analgesia,addicton-induction,movement restatraining,respiration depression,LD50:etc of morphine.It was found that TRH was entirely different from naloxone in that it was not antagonistic at all to the morphine effects mentioned above.So TRH would be a better choice than naloxone in the treatment of traumatic shock.

construction of a comprehensive,multifunctional and theory supported operation system is the organization basis on which occupation burnout can be scientifically and effectively interfered.Interference to occupation burnout is divided into nine subsystems by "participation" dimension which consists of organization,family and individual,and by "functional" matrix dimension which consists of the first grade prevention(development interfere),the second grade prevention(symptom interfere) and the third grade prevention(burnout interfere).Among these subsystems there exist factors of different target,content,mode and method etc.Their operation and interrelation form a complete working system via which an organization interferes occupation burnout.Promote the hospital management more scientificly and hominizaiton's in human resource.

Objective: : To investigate whether development of the sph e noid sinus affect the surgical approach via saddle area. Methods: The pneumatization of sphenoid sinus of 50 cadaver heads was studied through t hinner CT scanning of coronal, sagittal and axial position. The sphenoid sinus w as classified according to the degree of pneumatization of sphenoid sinus toward s sphenoid bone, small wing of sphenoid bone and epippium. Results: There were 4% conchal, 18% pre-sellar, 18% semi-sellar, 14% sellar, 46% sellar -occipital in 100 sphenoid sinus cases. The transversal diameter of left and ri ght was 18.48 mm and 17.58 mm; The sagittal diameter of left and right was 2 2.20 mm and 20.82 mm, The vertical diameter of left and right was 21.02 mm and 2 0.38 mm. The distance between centre track and the later wall of sphenoid sinus was 14.78 mm in left side and 15.18 mm in right side. Conclusion: Thinner CT scanning with coronal and sagittal position can clearly show pneum atization of sphenoid sinus on both sides. Different pneumatization of sphenoid sinus provide anatomical basis for choosing operation approach.

Objective To explore the relationship between the polymorphism of angiotensin converting enzyme (ACE) gene and essential hypertension complicated with left ventricular hypertrophy (LVH). Methods ACE gene I/D polymorphism in 150 healthy subjects, 80 essential hypertensive(ET)patients with LVH and 152 ET patients without LVH was detected by PCR. Left ventricular mass (LVM) was measured by echocardiography, and then left ventricular mass index (LVMI) was calculated. Results The frequencies of the ACE D allele in the ET patients with or without LVH were 0.493 and 0.514, respectively, and significantly higher than those in the healthy subjects (P

Objective To investigate the adherence mechanism of Candida albicans to host cells in molecular level. Methods and Results Yeast cell wall protein of Candida albicans were extracted, and purified fibronectin (Fn) adhesin was obtained from yeast cell wall extract. Fn adhesin was analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE), the molecular weights of Fn adhesin were 60kd and 105kd. In order to find out the effect of the protein on adherence to host cells, human buccal epithelial cells and Candida albicans cells were incubated at 37℃ for 2 hours on a rotator, and yeasts adhering to the surfaces of epithelial cells were assayed microscopically. The adherence rate of C.albicans to buccal epithelial cells was 44 7?6 28%, and after treating the epithelial cells with Fn adhesin, the adherence rate reduced to 28 3?6 18%, P
