Purpose:To assess the therapeutic value of perc utaneous portal vein chemoembolization (PVE) for primary hepatic carcinoma (PHC) with portal vein tumor thrombus. Methods:45 unresectable PHC with portal vein tumor thrombus cas es were randomly divided into two groups. The observation group was treated with transcatheter arterial chemoembolization (TACE)+PVE, while the control group wa s treated with TACE only. The changes of AFP, response rates of portal vein tumo r thrombus and survival rates of one year were analyzed respectively. Results:The levels of AFP before and after treatment were(730 ?190)?g/L and (515+?395)?g/L in the observation group,(752?183)?g/L a nd (710?213)?g/L in the control group respectively. The difference between t he two groups was significant (P

Objective To investigate the influence of Tanyu-Tongzhi (TYTZ)recipe on Rho/Rho kinase signal transduction pathway of myocardial ischemia-reperfusion injury in high fat-fed rats.Methods 60 SD rats were divided into 5 groups randomly,a sham-operated group,a model group,a western medicine control group,a high-dose group and a low-dose group of TYTZ recipe.The model of ischemia reperfusion of the myocardium was reproduced by ligation of left descending artery for 30 min followed by releasing the ligation for 2 hours in rats.The downstream substrates of ROCK myosin light chain (MLC) phosphorylation expression of myocardial tissues in rats were detected by Western blotting method.The levels of RhoA,ROCK Ⅱ mRNA were determined with RT-PCR.Results Compared with the model group,the expression of p-MLC and RhoA,ROCK Ⅱ mRNA were lower in low-dose group of TYTZ,there were significant differences between the two groups(P=0.004、0.003、0.018、0.004,P＜0.01).Conclusion The TYTZ Recipe can protect myocardium from MI/RI.The mechanism of action was related to its inhibiting the protein expression of RhoA,ROCK Ⅱ and p-MLC,restraining the activation of Rho/Rho kinase signal transduction pathway.

Cultivation of Medical Humanism Spirit has special value in the teaching of psychiatry,but which was ignored in the teaching. This paper explored the way to integrate humanistic spirit education into the teaching process of psychiatry.

Objective To evaluate the in vitro antiviral activity of HB-13,a compound derivant from berberine and its prodrug berberine,against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2). Methods Vero cells were cultured in vitro and infected with HSV.Then,various concentrations of HB-13, berberine,and aciclovir were used to treat these infected cells.The cytopathic effect was observed to deter- mine the antiviral effects and cytotoxicity of HB-13 and berberine.Results For HB-13,berberine and acy- clovir,the half toxicity concentration (TC_(50)) to Vero cells was 31.99,380 and more than 800?g/mL, respectively;the average half inhibitory concentration (IC_(50)) against HSV-1 was 1.328,more than 100,and 0.443?g/mL,respectively,the treatment index (TI) against HSV-1 was 24.09,less than 3.80,and more than 1805.87,respectively;the IC_(50) against HSV-2 was 1.344,more than 100,and 0.679?g/mL,respectively,the TI against HSV-2 was 23.80,less than 3.80 and more than 1178.20,respectively.Conclusion HB-13 possesses marked antiviral activity against HSV-1 and HSV-2 in vitro,while berberine does not.

OBJECTIVETo study the effect of Buyang Huanwu decoction (BYHWD) inducing angiogenesis on the neuroblast migration from the subventricular zone and its mechanisms after focal cerebral ischemia.

METHODThe middle cerebral artery occlusion (MCAO) was performed to mice for 30 minutes to establish the model. The rats were divided into sham group, model group, BYHWD group and endostatin group. BYHWD (20 g x kg(-1), ig) and endostatin (10 μg, sc) were administered 24 h after ischemia once a day for consecutively 14 days. At 14 d after ischemia, the density of micro-vessel and the number of neuroblasts in the ischemia border zone were determined by immunofluorescence staining. The mRNA and protein expression of cell-derived factor-1 (SDF-1) and brain-derived neurotrophic (BDNF) were examined by real-time PCR and Western blot.

RESULTCompared with the model group, BYHWD significantly increased the density of micro-vessel and the number of DCX positive cells in the ischemia border zone (P < 0.01), and significantly increased the SDF-1 and BDNF mRNA and protein expression (P < 0.01). Compared with BYHWD group, endostatin significantly reduced the density of micro-vessel and the number of DCX positive cells in the ischemia border zone (P < 0.01), as well as the SDF-1, BDNF mRNA and protein expression (P < 0.01).

CONCLUSIONBYHWD could promote the neuroblast migration from the subventricular zone via inducing angiogenesis after cerebral ischemia, the mechanism may be correlated with up-regulating the expression of SDF-1 and BDNF.

Objective To observe the effect of reperfusion therapy on the prognosis of acute myocardial infarction (AMI) complicated by eardiogenic shock(CS)in reperfusion era.Methods 89 cases of AMI with CS were included with 57 male and 32 female.50 cases received conservative therapy and 39 cases reperfusion therapy.28 of the 39 cases had suecessflll reperfusion and 11 eases failed.18 patients had intra-aortic balloon pump (IABP) within 1 hour of CS,they constituted an early group;35 patients treated with IABP 1 hour after CS were of a late group.A group of 36 cases were not treated with IABP (no IABP group).Results The mortality of the early group with IABP Was significantly lower than that of the late and no IABP group(33.3% vs.74.2% vs.86.1%,P＜0.01).The mortality of the group with sucessful reperfusion was significantly lower than that of unsuccessful reperfusion and conservative no IABP group (42.8% vs.81.8% vs.84.0%,P＜0.01).logistic regression analysis showed that successful reperfusion therapy (OR 4.232,95% CI 1.407～12.730,P=0.01) and THE TIME of using IABP(OR 0.22.95% CI 0.063～0.764,P=0.017)were independent risk factors for death.Conclusion Early successful reperfusion and early institution of IABP were the most important therapeutic measures for reducing mortaliIv of AMI complicated by CS.

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.
