OBJECTIVETo observe the lower gastrointestinal mesenchymal tumors CT virtual endoscopy and pathology, and to explore its possible mechanism.

METHODSSelect 80 patients suspected colon gastroenterology treat in the hospital gastroenterology department, randomly divided into experimental group and control group, 40 cases in experimental group were given CT virtual endoscopy and pathological check, the control group received conventional colonoscopy and pathological check, and all the results compared with the pathological results.

RESULTSCompared with the pathological test results, consistent rate with the experimental group reached 94.73%, the same rate was 92.85% in control group. The difference was not statistically significant (P > 0.05).

CONCLUSIONSCT virtual endoscopy can quickly image and draw detailed information, and can improve the sensitivity and specificity of cancer diagnosis greatly. Clinically, CT virtual endoscopy have the same function as colonoscopy, can replace colonoscopy, can be important complement of electronic colonoscopy by those who cannot tolerate electronic colonoscopy or have contraindications. Its value is worth taking a step forward in-depth study.

Objective To investigate the effect of Sufentainil on myocardial ischemia-reperfusion injury and caspase-3 to rat heart. Methods Ninety Wistar rats weighing 200-300g were randomly divided into 3 groups(n=30):sham group(group S), ischemia-reperfusion group (group I/R)and Sufentainil group (group SF). Each group was divided into 3 subgroups according to the time phases at 30, 60 and 120min(n=10).In group I/R and group S the animals were received normal saline intravenously. In group SF sufentainil 5μg/kg NS 20ml was given. After 24 h, all animals were anesthetized with intraperitioneal 20% urethane 1 mg/kg, intubated and mechanically ventilated. The chest was opened and heart exposed via thoracotomy.In group S , left artery anterior descending artery(LAD) was not ocluded. While in I/R and SF group myocardial ischemia was introduced by clamping LAD for40 min. The animals were killed at 30, 60 and 120 min of reperfusion respectively(n=10each). Cardiac tropoin I(cTnI), expression of caspase-3 and apoptosis of cell in heart tissues were measured at the same time.Ultrastructure of myocardium taking the from apex was examined by electron microscopy at the end of 120 min reperfusion. Results Compared with group S, the concentration of cTnI was increased in the other 2 groups(P<0.05).cTnI was significantly lower in group SF than in group I/R(P<0.05). Expression of caspase-3 and apoptosis index induced by myocardial reperfusion were attenuatated in group SF(P<0.05). The damage of myocardial ultrastructure caused by myocardial I/R were also significantly improved in group SF. Conclusion Sufentainil may relieve the heart cellular apoptosis by decreasing caspase-3expressing.

The bystander effect(BE) plays an important role in the gene therapy of cancer by the herpes thymidine kinase/ganciclovir(HSV-TK/GCV) system.It enhances the therapeutic efficacy of this system.Up to now,the exact underlying mechanism of the bystander effect remains unclear.A large body of evidence has indicated a close correlation of the connexin expression and gap junction in the targeted cells to the bystander effect.Here the publications concerning the relationship of gap junction with the bystander effect in the HSV-TK/GCV treatment have been reviewed.The possible cell death signals that can be transferred through gap junction to induce the bystander effect are also discussed.

Objective To investigate the methods of preoperation diagnosis and treatment of primary gastric lymphoma of mucosa-associated lymphoid tissue(MALT).Methods To analyze retrospectively the diagnosis and treatment of 54 cases of MALT lymphoma diagnosed surgically and pathologically.Results The most common symptoms were stomachache or discomfort.Of the patients with MALT lymphoma,85.2%(46/54)cases were diagnosed by preoperation gastroscopy with biopsy.Helicobacter pylori was found in 48 cases(88.9%).The overall resection rate for MALT lymphoma was 87%(47/54).The 5-year and 10-year survival were 77.1% and 72.9%,respectively.Conclusions It is obvious that MALT lymphoma is associated with Helicobacter pylori.Since no specific symptoms in gastric MALT lymphoma,the preoperative diagnosis is relied upon the application of gastrointestinal image,gastroscopy and repeated biopsy.The use of curative resection with the post-operative chemotherapy and/or radiotherapy to treat MALT lymphoma is reasonable.

Objectives To investigate the effect of rhEPO on newborn rats with necrotizing enterocolitis (NEC). Meth-ods Sixty newborn Sprague-Dewley (SD) rats at the age of 48 hours were randomly divided into 5 groups:control group, NEC group, and intervention groups 1, 2 and 3 treated with rhEPO. The rats were fed rat breast milk substitutes and stressed under hypoxia and cold exposure to establish NEC model. The rats with NEC were treated with different doses of rhEPO (0.1U/ml, 1U/ml and 10U/ml) in intervention groups. The expression of Bcl-2 and caspase-3 were measured by immunohistochemistry, and intestinal pathological changes were observed using HE staining. The value of positive expression was analyzed by IOD (integral optical density) image analysis system. Results Abdominal distention, decreased activity and unresponsiveness occurred in NEC rats 24 hours after stress exposure, and pale skin, decreased skin temperature and respiratory rhythm change were observed in severe cases. The symptoms appeared later and milder in three intervention groups. The NEC incidence of newborn rats was as followings:control group(0%), model group(60%), intervention group 1( 30%), intervention group 2(18.2%), intervention group 3(9.1%) and the difference was signiifcant between each group (P=0.008). The grades of intestinal injury, the expression of active caspase-3 and Bcl-2 were signiifcantly different among groups (P<0.01). Intestinal injury was the most severe and the expression level of active caspase-3 was the highest in NEC group. After rhEPO treatment, the intestinal injury and the production of active caspase-3 protein were decreased, and the expression of Bcl-2 was increased. Conclusions Oral rhEPO could decrease the ex-pression of intestinal active caspase 3, and increase the expression of Bcl-2. The protective effect of rhEPO on NEC is dosede-pendent.

Objective To learn the burnout and turnover intention of physicians from township hospitals in Xi County,Henan province,for reference of health administrators and healthcare institution managers.Methods Cluster sampling method and qualitative interviews were used and all physicians from such hospitals were sampled for questionnaire survey in 2014,with 1 70 scales distributed.The questionnaire was the Markov Burnout Inventory generic version revised by Li Chaoping,and turnover intention questionnaire was that revised by Liang Kaiguang.Results 140 physicians from such hospitals were found with zero or low burnout (94.6%);Collaborative care in the county poses great positive effect on promoting professionalism and interpersonal relations, yet has limited positive impact on reducing workload and performance appraisal stress and increasing their income.Conclusion It is imperative to enhance training of managers of such hospitals for them to learn the appraisal method with organizational scale,and build a humanistic concern mechanism for physicians,for purposes of improving the organizational environment and minimize the burnout and turnover intention of the physicians.

Medical tourism has grown into a booming market worldwide,which however remains at a startup stage in China given its fast development in recent years.This paper probed into the present status of medical tourism at home and abroad,discussed key roadblocks to tackle for medical tourism,including government regulations,medical resources,international certification,promotions and marketing,language barriers,and visa.On such basis,the authors come up with the following recommendations:enhance policy support and complete the governance of medical tourism; tap resources of public hospitals and encourage private involvement; encourage international certification of medical institutions to explore overseas medical tourism; encourage tourist firms to develop medical tourim products and promoting medical tourism; build brands and complete product lines.
