Objective: To observe the morphological changes of enteric deep muscular plexuses interstitial cells of Cajal (ICC-DMP) in rats with multiple organ dysfunction syndrome (MODS). Methods: Forty Wistar rats were randomly divided into control group and MODS model group. The enteric ICC-DMP network was observed using c-kit immunohistochemical staining with whole-mount preparation technique and confocal laser scanning microscopy , and the ultraslructural features of ICC-DMP was evaluated using transmission electron microscope. Results: Compared with those in control group, the distributions and densities of intestine ICC-DMP in MODS group were significantly decreased (P < 0. 05) , the ICC-DMP network was disrupted and the ultrastructural features of ICC-DMP were severely damaged. Conclusion: The ICC-DMP network was severely damaged in rats with MODS, and the mechanism of gastrointestinal dysmotility in MODS may be related to the morphological changes of ICC-DMP.

OBJECTIVE: To study the status quo and future trend of digestive system drugs used in our hospital. METHO-DS: The digestive system drugs used in our hospital between 2001 and 2005 were analyzed retrospectively in respect to drug kinds, consumption sum, DDDs, daily costs etc. RESULTS: Drugs for peptic ulcer and hepatobiliary diseases took a big proportion and experienced a year- on- year increase. No significant change was noted for the top 10 drugs on the lists of DDDs and consumption sum before and after the medical insurance reform, but their order changed a little. The DDDs of most of the cheap and effective drugs increased after the medical insurance reform. CONCLUSION: The consumption of antiulcer drugs and drugs for hepatobiliary diseases in our hospital assume an increasing tendency.

Objective To evaluate the efficacy of intensity-madulated radiotherapy(IMRT) as the primary treatment in nasopharyngeal carcinoma (NPC). Methods Between November 2001 and March 2006,147 newly diagnosed NPC patients were treated with IMRT. The disease was Stage I in 3 patients, Stage Ⅱ in 35,Stage Ⅲ in 67 and Stage Ⅳ in 42. For T1-2 disease,the prescription dose was 70 Gy to the gross tumor volume( GTVnx) and positive neck nodes ,60 Gy to the planning target volume I, and 50-56 Gy to the clinically negative neck. For T3-4 disease,the prescription dose was 74-78 Gy to GTVnx. The local control rate(LC),overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) were estimated by Kaplan-Meier method. Results The 3-year LC, OS, DFS and DMFS of the whole group were 93.2% ,93.5% ,72.6% and 74.4% ,respectively. T stage was a significant predictor of LC and OS. For patients with T1-2 and T3-4 disease,the LC was 100% and 86.9% (P=0.007) and OS was 95.5% and 91.3% (P=0.030), respectively. N stage was a significant predictor of OS, DFS and DMFS(P=0.03,0.004 and 0.0004,respectively). The grade Ⅰ+ Ⅱ and Ⅲ acute toxieities of parotid were 96.6% and 1.4%. The rate of grade Ⅱ xerostomia at 3-month, 6-month, 1-year and 2-year after radiotherapy were 43.0%, 12.0% ,4.9% and 3.2%. Conclusions The treatment results are promising according to our target definition and dose prescription protocol for nasopharyngeal carcinoma.

Objective To investigate the dynamic changes of cardiomyocyte apoptosis and Caspase-12 activation after coronary microembolization (CME) in rats. Methods The CME models were produced by injection of 42 μm microspheres (3000/0.1 ml) into the left ventricle during clampinduced ascending aorta occlusion for 10 seconds in adult male Sprague-Dawley rats (CME group).The sham-operation group was injected with saline instead (S group). The survivors were randomly divided into five groups: 3 h, 6 h, 12 h, 24 h and 4 weeks (n=10, each), respectively. In addition,10 rats were designed as normal control group. Cardiomyocyte apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. The expressions of Caspase-3, 12 and procaspase-3 and 12 were detected with Western-blot analysis. The activity of Caspase-12 was determined with fluorometric assay kit. Results (1)Compared with the shamoperation group and normal control group, the apoptosis rates of cardiomyocytes in CME group were significantly increased at each time point respectively (all P＜0.05). Apoptotic cardiomyocytes were found mainly in the border zones and infarct foci. The apoptosis rates of cardiomyocytes at 3 h, 6 h,12 h, 24 h and 4 weeks after CME were (1.76±0.68)%, (3.17±1.26)%, (1.34±0.12)%,(1.07±0.65)% and (0.30±0.13)%, respectively. The apoptosis rates of cardiomyocytes increased at 3 h after CME, peaked at 6 h after CME (all P＜0.05), and then gradually decreased with lowest value at 4 weeks (all P＜0.01). (2)Compared with sham-operation group and normal control group,the relative activation level of Caspase-3 and 12 in CME group increased remarkably (all P＜0.05).The time courses of Caspase-3 and 12 expressions corresponded well to those of cardiomyocyte apoptosis after CME. Conclusions The amount of cardiomyocytes apoptosis is significantly increased after CME. Caspase-12 may be involved in the apoptosis of cardiomyocyte after CME.

Nutrition therapy is an important part of the treatment of Crohn’s disease(CD),which plays an important role in correcting malnutrition,inducing disease remission,and for the perioperative management. Nutrition therapy, especially enteral nutrition(EN),has been studied for its effect on CD. We have long been focusing on the use of nutrition therapy in the treatment of CD,especially the use of EN in the perioperative management of CD. Here,we reviewed the indications,effects,endpoints and the underlying mechanisms of preoperative nutrition therapy,through which we hope can shed light on improving the optimization of preoperative management as well as the standardization of preoperative nutrition therapy in CD.

Objective To investigate the effects of ciprofloxacin on anastomotic stoma,small intestinal inflammation and fibrosis in interleukin-10 knock-out mice (mice model of Crohn′s disease (CD)) after ileocaecal resection.Methods Twelve interleukin-10 knockout male C3H/HeJBir mice were evenly divided into control group and ciprofloxacin group.The mice model was established with ileocaecal resection and ileocolostomy.There was no intervention in control group.Ciprofloxacin (50 mg/kg per day)was orally administrated in ciprofloxacin group for four weeks.All the mice were executed.The intestine around anastomotic stoma was taken for hematoxylin-eosin (HE)and Sirius red staining and histological scoring.The level of interferon (IFN)-γand tumor growth factor (TGF)-βin intestine around anastomotic stoma and small intestine was detected by enzyme-linked immunosorbent assay (ELISA) method.The content of procollagen α1 was determined by real-time polymerase chain reaction.The data were analyzed by t test.Results The inflammatory reaction level of anastomotic stoma and small intestine in mice of ciprofloxacin group (2.50±0.55 and 1 .67±0.52)was significantly lower than those of control group (3.67±0.63 and 2.83±0.75 ,t=-8.273,-5 .188,both P <0.05 ).The IFN-γof anastomotic stoma and small intestine also significantly decreased ((0.72 ±0.22 )pg/mg vs (1 .76 ±0.43 )pg/mg, (0.23±0.12)pg/mg vs (0.78 ± 0.52 )pg/mg;t = - 7.354,- 5 .268,both P < 0.05).However, ciprofloxacin could not significantly decrease fibrosis in anastomotic stoma and small intestine of CD mice. There was no significant difference in the level of TGF-βcompared with control group.Conclusions The role of ciprofloxacin in improving inflammatory reation in anastomotic stoma of CD mice was limited. Maintenance therapy may be necessary to reduce the relapse of anastomotic stoma diseases.

Background:As postoperative intra-abdominal septic complications( IASCs)in Crohn’s disease( CD)are difficult to manage,it is of great importance to prevent this condition in CD patients after surgery. Till now,there are no large sample studies on risk factors for postoperative IASCs in CD in China. Aims:To determine the risk factors for postoperative IASCs in CD for guiding the formulation of preventive strategies. Methods:This retrospective study was based on a computerized database of CD patients who had undergone surgery for CD complications between 1999 and 2014 at Nanjing General Hospital of Nanjing Military Command,PLA. Patients were divided into IASCs group and non-IASCs group. Thirty potential variables were selected,and both univariate and multivariate( Logistic regression)analyses were performed to identify the risk factors for IASCs after surgery. Results:Seven hundred and sixteen operations were reviewed,and IASCs occurred in 41 cases(5. 7%). By univariate and multivariate analyses,IASCs were significantly associated with one stage anastomosis(OR=1. 656,95% CI:1261-3. 279),preoperative low albumin level( <30 g/L)(OR=1. 457,95% CI:1. 152-2. 368),preoperative high CRP level( >10 mg/L)(OR=8. 641,95% CI:3. 376-16. 364),preoperative steroids use ≥3 months(OR=3. 785,95% CI:1. 237-4. 671)and presence of intra-abdominal abscess or infection at the time of surgery(OR=1. 784,95% CI:1. 155-3. 826). However,enterostomy(OR =0. 125,95% CI:0. 062-0. 561)and preoperative enteral nutrition ≥ 1 month( OR =0. 147,95% CI:0. 078-0. 781 ) were found to be the independent protective factors. Conclusions:Malnutrition,active CD and preoperative long-term steroids use increase the risk of postoperative IASCs in CD. Patients with these risk factors should not receive immediate surgery. If surgery is inevitable, enterostomy instead of resection and anastomosis should be the first choice. Preoperative enteral nutrition is helpful for reducing the occurrence of IASCs after surgery.
