International Journal of Cerebrovascular Diseases 2011;19(9):667-672
Objective To investigate the correlation between the expression of P-SAPK/JNK and neuronal apoptosis in the striatum during permanent middle cerebral artery occlusion (pMCAO) in rats.Methods Fifty-four male Sprague-Dawley rats were randomly divided into sham operation group and pMCAO 1-,3-,6-,12-,and 24-hour groups (n =9 in each group).Apoptotic neurons in the striatum during cerebral ischemia were detected by TUNEL assay,the nuclear translocation of P-SAPK/JNK in the striatum by immunohistochemical staining expressions of P-SAPK/JNK protein by Western blot.Results The numbers TUNEL- and P-SAPK/JNK-positive cells in the striatum at 1 hour after pMCAO increased significantly (P =0.000 1),and reached the peak at 6 hours.The numbers of TUNEL-positive cells decreased at 12 hours,however,it still higher than the sham operation group (P =0.000 2).Western blot analysis showed that the expression of P-SAPK/JNK after pMCAO increased significantly,and the time-course change was in accord with the result of immunohistochemical staining Neuronal apoptosis in the striatum was significantly positively correlated with the expression of P-SAPK/ JNK (r =0.984,P =0.000 4).Conclusions Cerebral ischemia may induce neuronal apoptosis in the striatum through the activation of P-SAPK/JNK.

Chinese Journal of Trauma 2014;30(7):735-739
Objective To investigate the effect of dopamine receptor in intestinal mucosal barrier function after brain injury in rats.Methods Twenty-four rats were allocated to control group,brain injury group,dopamine receptor group,and dopamine antagonist group according to the random number table,with 6 rats per group.Feeney' s weight-drop model was introduced to generate rat models of brain injury.Intestinal mucosal specimens were harvested at postoperative 7 days to evaluate intestinal mucosal morphology by HE staining,expressions of dopamine receptor D1 (DRD1) and dopamine receptor D2 (DRD2) by immunohistochemistry,and mRNA and protein expressions of DRD1 and DRD2 by real-time PCR and Western blot.Meantime,urinary samples were collected to measure lactulose to mannitol ratio (L/M) by high performance liquid chromatography (HPLC).Results Intestinal villus integrity was disrupted in brain injury group and dopamine receptor group when compared to control group,but it remained relatively intact in dopamine antagonist group.Ratio of L/M in brain injury group and dopamine receptor group was similar (0.192 ± 0.080 vs 0.183 ± 0.090,P > 0.05),far higher than 0.037 ± 0.008 in control group (P <0.01),but it was reversed in dopamine antagonist group (0.071 ± 0.008,P < 0.01).Real-time PCR showed DRD1 and DRD2 mRNAs expressed in brain injury group and dopamine receptor group were similar (0.764 ± 0.074 vs 0.718 ± 0.065,0.439 ± 0.051 vs 0.408 ± 0.090,P > 0.05),far higher than 0.189 ± 0.008 and 0.076 ± 0.011 in control group (P < 0.01),but both lowered in dopamine antagonist group (0.386 ± 0.071,0.270 ± 0.092,P < 0.01).estern blot analysis showed DRD1 and DRD2 proteins in brain injury group and dopamine receptor group were similar,but both were far higher when compared to control group (P < 0.01).Conclusion Impaired intestinal mucosal barrier may be relate to the up-regulated dopamine receptor in intestinal mucosa after brain injury in rats.

Objective To study the effect of hospital disposal manners after workplace violence in hos-pital on organizational commitment and turnover intention among the head nurses. Methods Self-made questionnaire about workplace violence in hospital and general condition, organizational commitment question-naire and turnover intention questionnaire were conducted in 122 head nurses who had suffered hospital vio-lence in recent years from all level hospitals of Fujian province. Results The scores of affective commitment and normative commitment of organizational commitment and turnover intention showed significant difference be-tween the groups who suffered positive disposal and who suffered negative interference by the hospital after the violence events (P<0.05), but aggregate score of organizational commitment and the scores of continuance commitment showed no significant difference between the two groups (P>0.05). Hospital disposal manners af-ter the hospital violence and hospital grade were influence factors on turnover intention among the head nurses.Hospital grade was also an influence factor on organizational commitment among the head nurses. Conclu-sions Hospital positive disposal means after the hospital violence on head nurse help to ameliorate organiza-tional commitment and reduce turnover intention among the head nurses.

Medical image segmentation is a classical puzzle for researchers.Image segmentation is the method to delineate anatomic structures or other interested regions automatically or semi-automatically,which is helpful to diagnosis and plays a crucial role in many medical imaging applications.In this article,a rather complete survey to medical image segmentation methods and their characteristics are given,especially to the new methods or improvement of the classical methods which was put forward recently.The prospects and the challenge of medical image segmentation is discussed.

Objective To evaluate the clinical efficacy of sodium tanshinone IIA sulfonate(STS)in the treatment of ad-vanced schistosomiasis. Methods Fifty cases with advanced schistosomiasis admitted to the Touzao Township Hospital of Dong-tai City during the period from November 2012 to November 2013 were treated with STS for 10 days,and the internal diameter of the portal vein,levels of ALT,AST,γ-GT,PIIIP,CIV,HA and LN were measured and compared before and after the adminis-tration of STS. Results The mean levels of all serological parameters except HA were within the normal range before STS treat-ment,while the highest positive rate was detected inγ-GT(26.0%)and HA(54.0%). Following the STS treatment,the mean lev-els of all parameters and the positive rates reduced,with the greatest reduction observed inγ-GT(36.7%)and HA(37.8%);how-ever,the mean HA level was still higher than the normal range. The mean internal diameter of the portal vein reduced from(10.5± 1.7)mm before the STS treatment to(9.8±1.3)mm after the STS administration,with a significant diffrtence(P<0.05). Conclu-sion STS appears effective in the treatment of advanced schistosomiasis.

Objective To study the pattern of intragastric acid secretion in bleeding ulcer patients to assess the role of gastric acid suppression in the prevention and treatment of ulcer bleeding.Methods 43 cases of peptic ulcer(PU) with ulcer bleeding and 53 cases of age-and sex-matched PU controls without ulcer bleeding were included. All patients received 24 hours gastric pH monitoring. PU was diagnosed by endoscopy. Hp infection was diagnosed by rapid urinase test, biopsy and C 13 breath test.SPSS software was used for statistic analysis.Results In bleeding group, average gastric pH in supine was 1 6,and the percent of accumulative time and the longest lasting time within 0~1 of gastric pH in supine were 21% and 26 0 minutes respectively,while in control group those were 2 0%, 4 5 minutes respectively.However, no differences of gastric pH were found between severe bleeding patients and other bleeding ones. Hp infection rate was 56 1%,54 8% in bleeding group and control group respectively.Conclusions Multiple factors might induce peptic ulcer bleeding. Higher gastric acid secretion at night might be one of the risk factors causing peptic ulcer bleeding.It is suggested that giving PU patients with a high risk of bleeding some acid inhibitor before sleeping may prevent PU hemorrhage. Hp infection may be the direct risk factor leading to ulcer bleeding.
