Objective To investigate the effect of escitalopram on the levels of serum proinflammatory cytokine interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),and IL-18 in a rat model of poststroke depression (PSD).Methods Twenty-four male Sprague-Dawley rats were randomly allocated into sham operation,middle cerebral artery occlusion (MCAO),PSD and escitalopram groups (n =6 in each group).A model of MCAO was induced by the intraluminal suture method,and on this basis,a PSD model was induced by combining with chronic unpredictable mild stress (CUMS) plus lonely upbringing.The rats of both the sham operation group and the MCAO group were neither CUMS nor lonely upbringing,and in the PSD group they were both CUMS and lonely upbringing.The escitalopram group was given escitalopram intervention (10 mg/kg · d,intraperitoneal injection for 3 weeks) at the beginning of CUMS and lonely upbringing.At baseline and on day 7,14 and 21 after CUMS,sucrose solution consumption and wilderness trials were used to assess depression-like behavior.Enzyme-linked immunosorbent assay was used to detect the levels of serum proinflammatory cytokines IL-6,TNF-α and IL-18 on day 21 after CUMS.Results On day 21 after CUMS,the scores of weight,sucrose solution consumption,vertical test and the distance of horizontal activities were all significantly decreased and shortened compared to those of the sham operation group and the MCAO group (all P＜0.01).The weight,sucrose solution consumption,and the distance of horizontal activities of the escitalopram group were significantly increased compared to those of the PSD group (P ＜0.05 or P ＜0.01).On day 22 after CUMS,the serum IL-18 level of the PSD group was increased significantly compared to that of the sham operation group and the MCAO group (P ＜ 0.05 or P ＜ 0.01).The serum IL-18 level of the escitalopram group was decreased significantly compared to that of the PSD group (P ＜0.05).However,there were no significant differences in the levels of IL-6 and TNF-α among all the groups.Correlation analysis showed that on day 22 after CUMS,the serum IL-18 level and sucrose solution consumption (r =-0.415,P =0.044),the distance of horizontal activities in the wilderness trials (r =-0.508,P =0.011) showed a significant negative correlation,however,they did not have significant correlation with the vertical score (r =-0.390,P=0.059) and the body weight (r=-0.216,P=0.311).Conclusions The serum IL-18 level is increased significantly in the PSD rat models.Escitalopram can significantly decrease the serum IL-18 level and improve depression-like behavior of the PSD rats,suggesting that IL-18 may play a role in the pathogenesis of PSD.

Objective To investigate the changes of T cell subsets including Th1,Th2,Th17 and Treg in the hand,foot and mouth disease(HFMD) patients.Methods 35 EV71 induced HMFD patients and 12 non-infectious children were included in this study.Patients were divided into mild symptoms group and severe symptoms group.The ratios of Th1,Th2,Th17 and Treg were analyzed by flow cytometry.Results Sixteen mild cases and 19 severe cases were included in the 35 patients.No statistical difference of children′s age and sex were found among the groups(P>0.05).The proportion[M(P25,P75)] of Th1 cells of mild and severe groups were 10.65%(8.73%,14.08%) and 15.51% (13.47%,18.31%),respectively,which were significantly higher than normal control group 5.51% (3.61%,8.61%)(P<0.05).The proportion of Th2 cells of mild and severe groups were 4.32%(2.60%,5.32%) and 3.87% (2.34%,5.32%),no significant difference from control group 2.11% (1.02%,5.11%)(P<0.05).The proportion of Th17 cells of mild and severe groups were 8.32%(5.25%,12.33%),7.36% (5.05%,11.9%),significantly higher than that of normal control group 4.23% (2.44%,6.22%)(P<0.05).The proportion of Treg cells of mild and severe groups were 1.46% (0.31%,2.73%),1.59%(0.35%,2.62%),no significant difference from the control group 1.78% (0.31%,2.77%)(P<0.05).Conclusion The Th1/Th2 and Th17/Treg ratios of HFMD patients with EV71 virus infection were changed,and the Th1 and Th17 cells may play an important role in the in the disease and body′s resistance.

Objective To compare the short-term results of rectal cancer treated either by laparoscopic or open total mesorectal excision(TME). Methods A series of 165 unselected consecutive patients with rectal cancer from August 2002 to December 2005, who decided to accept the laparoscopic or open TME, were included in this study. The following parameters were compared between the two groups: length of the surgical specimen, distance between the distal incisal edge of the rectum and the inferior margin of the tumor, the number of the lymph nodes resected, local recurrence rate, incidence of distant metastases, and 2 year survival rate. The mean follow-up period for both groups was 26.9 months (range, 6-46 months). Results Demographic data and Dukes stage were matched in two groups. The mean length of the resected specimens was 24.4 cm in the laparoscopic TEM group and 25.2 cm in the open TEM group. The distance from the distal incisal edge of the rectum to the inferior margin of the tumor was 2.9 cm in the laparoscopic TEM group and 2.7 cm in the open TEM group, and the mean number of lymph nodes scavenged was 11.5 in the laparoscopic TEM group and 10.6 in the open TEM group. The local recurrence rate after laparoscopic resection was 9.6%, as compared with 11% after open resection. Distant metastases occurred in 11.5% of the patients in the laparoscopic group, whereas it was 14.6% in the open group. Two year survival rate was 85.7% and disease free survival was 76.2% after laparoscopic resection and compared to 78.8% and 69.7% after open resection. All above parameters did not show statistically different between the two groups. Conclusion The oncologic resection and the early outcomes are comparable between the two surgical approaches.

Objective To evaluate endovascular management for isolated iliac artery aneurysm (IIAA). Methods From May 1997 to Jan 2006, 15 IIAA cases underwent endovascular treatment, including 12 true aneurysms and 3 psudoaneurysms. There were 9 common iliac artery aneurysms (CIAA), 3 internal iliac artery aneurysms (IIAA) , and 3 external iliac artery aneurysms (EIAA). The average diameter was (5. 97?1. 49) cm (3. 5-9. 0 cm). IIAA was treated with metallic coils and CIAA/EIAA by stent-grafts. Results Unilateral internal iliac artery was preserved in 14 cases, and bilateral internal arteries were preserved in one case. Postoperative endoleak was found in 2 cases. There was no other major complications nor mortality. One case suffered buttock claudication because of internal iliac artery exclusion. The operation time was 1. 9?1. 1 h, blood loss was 126. 7?70. 1 ml. Patients were up and about after 2. 1?1. 1 d, hospital stay was 5.5?4.7 d. Conclusions Endovascular treatment is safe and effective for isolated iliac artery aneurysm. Internal iliac artery preservation and prevention of endoleak is of great importance.

OBJECTIVE: To study the clinical effect of Treatment of blow-out fracture of medial orbital wall with nasoseptal cartilage under nasal endoscope. METHOD: Under a nasal endoscope, the fracture and the prolapsed orbital contents were reduced to the orbit, and then an autogenous nasoseptal cartilage was grafted into the orbital defect. The variations in the visual acuity, diplopia, enophthalmos degree and eyeball position were detected preoperatively and postoperatively. RESULT: During the follow up of three months to four years after operation, all the 28 cases showed neither loss nor distinct descent of visual acuity. The postoperative mean enophthalmos degree (1.5 +/- 0.6) mm was lower than the preoperation one(3.6 +/- 1.1) mm (P<0.05). Diplopia disappeared completely of 25 cases during 3 month after operation,while it appeared in the primary position of 2 cases. The eye movement was normal of 26 cases after operation t, and the abduction was slightly limited of 2 cases, but which was better than be for). Any displacement of filling material, infection, rejection reaction were not found of all the 28 cases. CONCLUSION The medial orbital blow out fracture with nasal endoscope has many advantages, such as short operative route, clear surgical visual field, simple performance, light injury and no scars, and the effect of which will be really certain in the operative practice.
