Objective To evaluate the effects of antiviral therapy in prevention of tumor recurrence after curative treatment for patients with hepatocellular carcinoma (HCC). Methods Between Apr. 2006 and Jun. 2009,60 patients undergone curative treatment for HCC were enrolled in the retrospective analysis. Patients were assigned into four groups (15 each):patients in groupⅠ(serum HBV-DNA≥1.0?105copies/ml) and groupⅡ(serum HBV-DNA

0.05). The score of HAMD(38.1?4.0/33.4?4.7,t=4.35), HAMA(22.6?5.5/11.7?2.7,t=10.93), GDS(14.0?1.2/12.1?2.0,t=4.92) of comorbidity group was significantly higher than that of the depression group. The social function (SF)(70.0?21.2/50.0?22.5,t=4.02) and physical function (PF)(79.2?13.6/69.1?13.6,t=3.25) scores of SF-36 were significantly higher in depressive group than in comorbidity group. Conclusion: Comorbid depression and anxiety and anxious depression are associated with more severe overall psychopathology than nonanxious depression in elderly persons, similar to observations in younger adults.

OBJECTIVETo investigate the injury stress responses caused by ischemia reperfusion and its effects on the salivary secretory function of rat submandibular glands.

METHODSAn in situ ischemia reperfusion experimental model of rat submandibular glands was developed. The rat submandibular glands were subjected to 90 min of ischemia without denervation followed by reperfusion for 1, 12, 24, and 72 h. Salivary secretion, histological changes, reactive oxygen species (ROS) levels, and cellular apoptosis of the involved submandibular glands were detected after reperfusion.

RESULTSThe secretory function of the glands decreased at 1 and 12 h, and the saliva secretion gradually had the same value as that of the control sample 72 h after reperfusion. Increasing inflammatory cells infiltration, cellular atrophy, and tissue edema were observed especially after reperfusion for 12 h. The level of ROS and the number of apoptotic cells exhibited the same tendency, and higher ROS levels and more apoptosis cells 1 and 12 h after reperfusion were observed.

CONCLUSIONOur study suggests that ischemia reperfusion can cause a series of injury stress responses in submandibular glands, which might have an important function in the early phase dysfunction of transplanted submandibular glands.

Objective To evaluate the efficacy of entecavir in lamivudine-refractory patients with chronic hepatitis B.Methods Literature from Medline,Embase and CBM between January 2001 to December 2008 were reviewed.Acccording to the including and excwding criteria,four randomized controlled trials (RCT) were enrolled.The results of the trials were reviewed and analysed in software Revman 4.2.Results Patients in the entecavir group enjoyed significantly higher negative conversion ratios of HBV-DNA and ALT,and positive seroconversion of HBeAg:RR were 13.90(95% CI 6.39～30.24,P＜0.00001),2.49(95% CI 1.40～4.45,P=0.002),and 3.53 (95% CI 2.85～4.38,P＜0.000 01) respectively.There was a trend for the improvement of negative conversion ratio of HBeAg (RR=2.27,95% CI 1.00～5.15,P=0.05),but the incidence of side-effects of the drugs has no difference (RR=1.05,95% CI 0.97～1.14,P=0.21).Conclusions Compared with lamivudine or placebo,entecavir can significantly decrease HBV-DNA,improve liver function and positive seroconversion ratio of HBeAg without raising the incidence of drug side-effects.

Objective To study the preventive effects of vitamin K2 on tumor recurrence in patients with hepatocellalar carcinoma (HCC) after radical resection. Methods The clinical data of 50 patients with HCC who received radical resection from March 2006 to March 2007 in No. 181 Hospital of PLA were analyzed retrospec-tively. All the patients were divided into 2 groups according to the random number table. Twenty-six patients in vitamin K2 group were administered with menatetrenone (45 mg per day), and the rest 24 pateints were in the control group. The accumulative and tumor-free survival rates, differences between the 2 groups, multivariate factors for prognosis were analyzed by Kaplan-Meier curve, Log-rank test and Cox regression model, respectively. Results During a period of 36 month follow-up, 10 patients died and 28 had tunor recurrence. The 1-, 2-, 3-year accumulative survival rates were 96%, 92% and 83% in vitamin K2 group, and 96%, 82% and 63% in control group (χ2 = 3.61, P > 0.05). The 1-, 2-, 3-year tumor-free survival rates were 92%, 60% and 38% in vitamin K2 group, and 75%, 42% and 12% in control group, with significant difference between the 2 groups (χ2 =5.61, P <0.05). Univariate and multivariate Cox proportional hazard analysis showed that without taking menate-trenone, the preoperative level of alpha fetoprotein (AFP) ≥800 μg/L and vascular invasion were the indepen-dent risk factors for tumor recurrence. Conclusions Vitamin K2 has a suppressive effect on tumor recurrence of HCC, while patients with AFP≥800 μg/L before operation or with vascular invasion have poor prognosis.

To compare the effects of four different intensive insulin therapies on blood glucose control and vascular endothelial function in newly-diagnosed type 2 diabetes.Patients were randomly divided to accept pre-meal insulin aspart 30 or pre-meal insulin aspart and glargine at bedtime or pre-meal Novolin-R and NPH at bedtime or continuous subcutaneous insulin aspart infusion.Capillary blood glucose determination and continuous glucose monitoring system were carried out,therapeutic time and total insulin dosage were recorded.Ultrasound was used to evaluate the vascular endothelial function.Glucose level,incidence of low glucose,potency ratio of the four groups were similar( P＞0.05 ) ; FMD and NMD were not significantly improved ( P =0.718,P =0.065 ).The short-term efficacy and safety of the four groups are similar.The short-term intensive insulin therapy has no obvious effect on vascular endothelial function.

Objective To evaluate the diagnostic value and limits of 64-slice spiral coronary artery imaging,by com- parison with selective coronary angiography,in detection of coronary heart disease.Methods Fourty-two patients sus- pected CAD were performed 64-slice spiral CT coronary imaging and selective coronary artery angiography in two weeks, comparative analysis of results were progressed consequently.Results The sensitivity,specificity and positive and nega- tive predictive value to identify≥50% stenosis branches was 90.5%,96.6%,85.9% and 97.8%,respectively.The sen- sitivity,specificity and positive and negative predictive value to identify≥75% stenosis branches was 93.5%,98.9%, 87.9% and99.4%,respectively.Conclusion As a noinvasive quantitative assessment of coronary artery stenoses exami- nation,64-slice spiral CT is a valuable method to detect and diagnose the disease of coronary artery,but its clinical use maybe presently be limited due to image quality in a number of cases.
