To evaluate the inhibitory effect of recombinant adenovirus carrying human endostatin gene (Ad-endo) on the growth of human pancreatic carcinoma xenograft in nude mice. The expression of endostatin in human pancreatic carcinoma Capan-2 cells was examined by RT-PCR after infection with Ad-endo. The supernatants of Capan-2 cells were collected after 48 h of infection with Ad-endo as the conditioned medium for human umbilical vein endothelial cells (HUVECs), whose proliferation in vitro was assayed. Capan-2 cell xenografts were established to determine the antitumoral effects of Ad-endo in vivo. The intratumoral microvessel density (MVD) was evaluated using CD31 staining. The expression of endostatin gene was detected by PT-PCR in infected Capan-2 cells. The conditioned medium from Ad-endo-infected cells significantly inhibited HUVEC proliferation (P<0.05). Ad-endo significantly suppressed the growth of Capan-2 tumor xenografts in nude mice (P<0.05), and the MVD decreased significantly in the treated tumor (P<0.05) as compared with that in the control group. Adenovirus carrying human endostatin gene produces inhibitory effects on the growth of human pancreatic carcinoma tumors in nude mice. Source

To summarize multi-detector row CT (MDCT) and magnetic resonance imaging (MRI) features of retinal detachment and evaluate the diagnostic value of these two imaging modalities. The MDCT and MRI manifestations were reviewed in 45 cases (47 eyes) of retinal detachment, among which 16 cases (17 eyes) were examined by MDCT and 29 cases (30 eyes) by MRI. Thirty-two cases (33 eyes) were confirmed by operation, and the other 13 cases (14 eyes) were confirmed based on the clinical findings. MDCT and MRI displayed signs of fluid retention between the detached retina and the posterior wall of the eyeball in the cases. Among all these cases, 21 eyes showed simple retinal detachment and 26 had also other pathologies (hemorrhage in 20 eyes and calcification in 6 eyes). Choroidal osteoma was identified in 3 eyes and melanoma of choroid in 5 eyes. MDCT is sensitive in detecting calcification in the eyes and MRI with a minimal risk of radiation, and shows advantages in displaying hemorrhage and confined retinal detachment. Both MDCT and MR have high clinical value in the diagnosis of retinal detachment, and their choice depends on the individual condition of the patients. Source

To study the clinical effect of segmental resection of the liver using Glissonean pedicle transection for primary liver cancer. The clinical data of 55 primary liver cancer patients admitted from January 2006 to October 2008 were analyzed retrospectively. Twenty-five of the patients underwent segmental resection of the liver by Glissonean pedicle transection (group A), and 30 underwent routine hepatectomy (group B). The positivity rate of the resection margin, micrometastasis in the hepatic parenchyma surrounding the lesions and postoperative recurrence rates were investigated. The positivity rate of the resection margin was 4.0% in group A, significantly lower than that of group B. The number of histological micrometastasis was significantly higher in group A than in group B (16 vs 8). The median distance of histological micrometastasis was 6.8 mm (2.7-25.6 mm) in group A and 4.2 mm (2.4-9.0 mm) in group B. The one-year recurrence rate was significantly lower in group A than in group B (16% vs 26.7%). Glissonean pedicle transection for segmental liver resection is a simpler procedure than routine hepatectomy for primary liver cancer and can reduce the number of histological micrometastasis and recurrence rate.

To evaluate the efficacy and toxicity of the combined therapy with oxaliplatin and capecitabine (XELOX) in patients with advanced or recurrent gastric cancer. Forty-one patients with previously untreated advanced or recurrent gastric cancer received intravenous infusion of oxaliplatin at the dose of 130 mg/m(2) on day 1 and oral administration of capecitabine at 1000 mg/m(2) twice a day on days 1-14. The chemotherapy was repeated every 2 weeks for a median of 4 cycles. Two of 41 patients achieved a complete response, and 15 had partial responses, with an overall response rate of 41.5%. Stable disease was observed in 11 patients and progressive disease in 9. The median time to progression and overall survival was 6.2 months and 11.8 months. All the 41 patients were evaluated for toxicity according to NCI criteria, 4 showed grade 3-4 neural toxicity, 4 had hematological toxicity and 3 had hand-foot syndrome. The XELOX regimen shows good efficacy with an acceptable toxicity profile in advanced or recurrent gastric cancer patient. Source

Objective To observe the effects of systematic mental intervention, with combined centralized teaching, group interview and individual consulting, on mental health, personality and coping style in recruits, and explore an optimal intervention model for recruits' mental health. Methods Two thousand and sixteen recruits in one unit were involved in the present study, among them 1064 were allocated to study group, and the remaining 952 to control group. Recruits in study group received centralized teaching with battalion as a unit, and received group interview in squad or platoon as a unit, and meanwhile individual interview was conducted. Symptoms Checklist-90 (SCL-90), Eysenck Personality Questionnaire (EPQ) and Simplified Coping Style Questionnaire (SCSQ) were filled one month after they were enlisted in the army and 3 days before the training ended. Recruits in control group undertook the same tests mentioned above only 3 days before the training ended. Results The total score and factor scores except hostility in SCL-90 test were significantly lower after than before systematic mental intervention (P<0.05), the hostility score was slightly higher than before intervention but with no statistical significance (P>0.05). The total score and factor scores except paranoia in SCL-90 test were significantly lower in study group than in control group after intervention (P<0.05). Scores of extraversion-introversion tendency and nervousness were significantly lower after than before intervention (P<0.001), the scores of psychoticism and social lie were slightly higher but with no statistical significance (P>0.05), the score of active coping was significantly higher (P<0.001), and of negative coping was significantly lower (P<0.001) after than before intervention. The ratio of the score over 2 and above declined obviously (P<0.05) in neurosis, SCL-90 abnormality, SCL-90 total scores, number of positive items, somatization, obsession, interpersonal sensitivity, depression, anxiety, hostility, phobia, paranoid, and psychotic factor after than before intervention in recruits. Conclusion Systematic mental intervention, which consisted of combined centralized teaching, group interview and individual consulting, may promote the mental health, personality and coping style in recruits.
