The cultural development needs of contemporary college students generally are displayed as varied contents,rich types and distinctive characteristics.Students in military medical universities shoulder the responsibilities of both soldiers and medical students,their cultural development needs are often in contradiction to military culture,thus bringing challenges to the culture construction in military medical universities.By introducing activities from civilians and soldiers,constructing hidden cultural platforms,improving hardware facilities and other innovative methods,we can actively guide students' ideological direction and play a better culturally educational function of military schools.

Objective To study the relationship between serum leptin and fibrosis in chronic hepatitis B incorporate alcoholic liver disease(CHB + ALD) patients.Methods Select 17 male patients with CHB+ALD,15 male patients with liver cirrhosis(LC) ,19 male patients with chronic hepatitis B(CHB) and 12 male healthy persons as normal control(NC).Serum leptin is detected by ELISA in 63 patients.Serum levels of fibrosis markers(HA,LN,PC HI ,IV-C) are determined at the same time.Results Serum leptin level in CHB +ALD are significantly higher than those of the NC(6.79±24.12) μg/L vs (4.27±7.18 ) μg/L (P＜0.05).There is no significant difference between patients with CHB and the NC.The four fibrosis markers in CHB + ALD patients are significantly higher than that of men both in the CHB and the NC.There are significant correlations between both serum leptin level and quadrinomial fibrosis markers(P＜0.05 or P＜0.01 ).Conclusion That serum leptin level is one aecelerate gene in the fibrosis formation in patients with CHB+ALD.

The authors designed to separate, purify and determine the monosaccharide composition of the polysaccharide from Cordyceps militaris, and study its effect on reverse cholesterol transport in vivo by isotope tracing assay. Polysaccharides were separate and purify by ion exchange column Q-sepharose Fast Flow and size exclusion column Sephacryl S200HR; the molecular weight and monosaccharide composition of the polysaccharides were determined by high performance gel permeation chromatography and high performance liquid chromatography coming with pre-column derivation, respectively. Finally, three purified polysaccharides CMBW1, CMBW2 and CMYW1 were obtained, their total carbohydrate contents were 87%, 89%, 95%, respectively; their protein contents were 6.5%, 1.3%, 2.8%, respectively; their molecular weights were 772.1, 20.9, 13.2 kDa, respectively; CMBW1 was composed of mannose, glucosamine, rhamnose, glucuronic acid, glucose, galactose and arabinose with a molar ratio of 7.25: 0.17: 1.29: 0.23: 6.30: 11.08: 0.79; CMBW2 was composed of mannose, glucosamine, galactose and arabinose with a molar ratio of 2.40: 0.16: 2.92: 0.24; CMYW1 was composed of mannose, glucosamine, glucuronic acid and glucose with a molar ratio of 0.59: 0.57: 0.45: 25.61. Polysaccharide at 50 mg x kg(-1) could significantly improve the transport of 3H- cholesterol to blood and excretion from feces. All of the three purified polysaccharides CMBW1, CMBW2 and CMYW1 were heteropolysaccharide; and they could improve reverse cholesterol transport in vivo, the underlying mechanisms are being studied.

In order to find new cephalosporin with more and more potent antibacterial activity, nine new fourth-generation cephalosporins (N1-N9) were synthesized from ethyl 2-(2-aminothiazol-4-yl)-(Z)-2-methoxyiminoacetate (1) via acylation, substitution, hydrolysis, active esterification, condensation and salt formation. The structures of compounds (N1-N9) were confirmed by IR, MS, 1H NMR and elemental analysis. The target compounds possess different antimicrobial activities against Gram-positive and Gram-negative bacteria. The preliminary results of antibacterial activities revealed that they showed better antibacterial activities against Gram-positive bacteria than cefpirome sulfate. In particular, their activities against Staphylococcus aureus and Streptococcus albus are better.

Objective To explore the clinical application value of MRA (TOF and PC)in cerebrovacular arteriovenous malforma-tion imaging when DAS as a reference gold standard.Methods 60 patients clinically suspected cerebral vascular malformations were enrolled in our study.They were all underwent MRA (TOF and PC)and DSA examinations successively within three days.Then, the imaging of feeding arteries,vascular malformation masses and venous drainages were compared and analyzed.Results Of all 60 patients with AVM,their feeding arteries and arterioles images were showed better by DSA and MRA-TOF technology than by MRA-PC.The difference was statistically significant (χ2/P DSA?PC - 4.1 75/0.000,χ2/P TOF ?PC - 3.508/0.000 ),no statistically difference was found between DSA and MRA-TOF findings,(χ2/P DSA?TOF -0.740/0.459).However,their venous drainages and venules show better with DSA and MRA-PC technology than with MRA-TOF method,the difference was statistically significant (χ2/P DSA?TOF -2.445/0.014,χ2/P PC?TOF -3.443/0.001),no statistically difference was found between DSA and MRA-PC findings (χ2/P DSA?PC -1.085/0.278).Conclusion MRA-TOF to display cerebral arteries and MRA-PC to show cerebral venues are basically consistent with the DSA,MRA-TOF and MRA-PC cannot replace each other when showing cerebral arteries and venous.

Aim To study the effect of proteasome inhibitor MG132 on expression of Caspase-3 and UPP associated genes in the apoptosis of human hepatocelluar cancer cells.Methods HepG2 cells were treated with MG132 (2,5,10 ?mol?L -1) for 24 h. The apoptotic cells were determined with flow cytometric analysis. The levels of E1, E2, E3 and Caspase-3 mRNA expression were detected with RT-PCR. Caspase-3 protein expression was detected with immunohistochemistry. Results The results showed that the increase of the degree of HepG2 cell apoptosis was concentrationly dependent. RT-PCR showed that E1, E2 and E3 gene expressions were decreased in the treatment group. MG132 down-regulated the gene expression of E1, E2, E3 and up-regulated the gene/protein expression of Caspase-3. Conclusion Proteasome inhibitor MG132 may induce HepG2 cells apoptosis by inhibitting UPP activity,up-regulating the gene/protein expression of Caspase-3.

OBJECTIVETo investigate three-dimensional kinematics of the superficial and deep portion of triangular fibrocartilage complex (TFCC) in different parts of the forearm rotation.

METHODSSix wrists of 6 volunteers were used to obtain CT scans at different positions of the wrist. The wrists were scanned from 90 degrees of pronation to 90 degrees of supination at an interval of 30 degrees. The 3-dimensional radius and ulna were reconstructed with customized software and changes in length of the superficial and deep portion of TFCC during forearm rotation.

RESULTSIn forearm pronation, the superficial dorsal portion and the deep palmar portion of the TFCC were tight. While the superficial palmar portion and the deep dorsal potion of the TFCC were lax. In supination, the changes in length of all these fibers were reverse.

CONCLUSIONSIn forearm rotation one portion fibers of dorsal TFCC and one portion fibers of palmar TFCC are tight, and this mechanism controls stability during DRUJ rotation.

Objective: To investigate the changes of myo cardial contractile function during myocardial stunning in calcium overload rats and the protective effects of tetrandrine. Methods: Forty-six rats were randomized into control, myocardial ischemia, myocardial stunning, low and high dose of tetrandrine groups. Another 10 rats were used to identify the calcium overload. vitamin D3 (0.3 million Unit/kg) and nicotinic acid were adm inistered. After 16 d when calcium overload occured, left anterior descending ar tery was ligated. Twenty minutes of myocardial ischemia followed by 60 min of re perfusion was induced. The contractile function parameters were determined dynam ically. At the end of experiment, myocardial cytosolic ［Ca2+］i was deter mined in various groups. In tetrandrine groups, tetrandrine (62.2 or 93.6 μmol/ kg ) was administered by gastrogavage daily.After 16 d, the rats undergone the e xperiments mentioned above. Results: Sixteen days after vitamin D3 , nicotinic acid were given, ［Ca2+］i increased by 2.6 folds (146.8±10.8 ) vs (368.5±22.6) nmol/L, (P<0.01). Whereas, ［Ca2+］i in tetrand rine groups were (210.8±16.4) and (198.6±15.3) nmol/L, which were significantl y lower than that of calcium overload group. Twenty minutes of myocardial ische mia resulted in the decrease of dp/dtmax and Vmax in all groups with the most si gnificant in stunning and calcium overload groups. The contractile function rest ored gradually after reperfusion. At all time points, dp/dtmax and Vmax in both tetrandrine groups were higher than those in both stunning and calcium overload groups. And effect with higher dose of tetrandrine were more significant than in low dose of tetrandrine. After 60 min of reperfusion, dp/dtmax in stunning, cal cium overload, low and high dose of tetrandrine groups were 49.7%, 51.5%, 71.0% and 83.4% of that in control, respectively， and Vmax were 55.0%, 49.8%, 73.9% and 77.5% of that in control, respectively. Conclusion: T he myocardial contractile function in vitamin D3-induced calcium overload gro up is impaired. On basis of myocardiocyte calcium overload, transient ischemia l eads to myocardial stunning. At the stage of ischemia, the impaired degree of my ocardial contractile function is similar to that in stunning group, suggesting a t this stage the effect of ischemia on myocardial function is greater than that of calcium overload. Tetrandrine chronically improves the myocardial function in Vitamin D3-induced calcium overload rats.
