Objective To explore the effects of recombined human growth hormon-enhanced early enteral nutrition on healing of the patients after operation for sereve abdominal trauma.Methods 60 patients with severe abdominal trauma were randomly divided into PN(n=20),EN(n=20) and EN+ rhGH(n=20) groups.Nutrient status and immune function of 3 groups were detected on the postoperative day 1,7 and 10.Results EN+ rhGH group showed more effective process than EN and PN groups in improving postoperative nutrient status,immune function and nitrogen balance,whose indexs except CD8 changed significantly on the postoperative day 7 and 10 than that in PN group(P

Objective To investigate the protective effects of green tea polyphenols(GTPs)on dopamine neuron loss in substantia nigra concomitant with a depletion of dopamine in corpus striatum induced by the N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)in mice as a model of Parkinson disease.Methods Male C57BL/6 mice were intraperitoneally injected with saline + saline(group A),saline + GTPs(group B),saline+MPTP(group C)and GTP+MPTP(group D)at 2-hour intervals for a total of 3 doses for MPTP and 5 doses for GTPs(10 or 50 mg/kg delivered).The animals were sacrificed 7 d after the last injection.Levels of dopamine and its metabolites in the corpus striatum were measured with high-performance liquid chromatography with an electrochemical detector(HPLC-ECD).Results Level of dopamine and its metabolites in the corpus striatum in group C decreased significantly compared with group A or B;however,those in group D(both 10 and 50 mg/kg)prevented these effects.Conclusion GTPs can protect the dopamine neurons from loss in MPTP-induced mice.

Objective: To explore the impact and mechanism of disease management of caregivers on self-management behaviors among patients with chronic heart failure. Methods: A total of 231 dyads of outpatient chronic heart failure patients and their caregivers were assessed by caregivers contribution to self-care of heart failure index (CC-SCHFI), self-care of heart failure index (SCHFI) and Atlanta heart failure knowledge test (AHFKT-V2). IBM SPSS 22.0 was used to conduct the paired t test and Pearson correlation analysis. LISREL 8.80 was used to conduct the path analysis. Results: There were significant differences between caregivers and patients in maintenance behavior (P=0.015), management behavior (P=0.023) and self-efficacy (P=0.001). There was no correlation between caregiver self-efficacy and patient heart failure knowledge and skill, but other variables were positively correlated, and r value ranged from 0.129 to 0.575 (P<0.05). Patient self-management behaviors were directly influenced by caregiver disease management, patient heart failure knowledge and skill and patient self-efficacy, and indirectly influenced in part by caregiver disease management through patient heart failure knowledge and skill and patient self-efficacy. Conclusion: Caregiver disease management not only can directly influence patient selfmanagement behaviors, but also can indirectly influence patient self-management behaviors through patient heart failure knowledge and skill and selfefficacy. Health care workers should carry out family-centered health education, and help caregivers actively participate in disease management of patients with heart failure; for those patients whose caregivers can't change their disease management behaviors, health care workers should also improve their selfmanagement behaviors by improving patients' heart failure knowledge and skill and self-efficacy.

Root canal therapy is the most efficient way to treat pulptitis and periapical inflammation, which can clear infections of root canal systems, fill the root canal firmly, and avoid reinfection. However, the variations in root canal morphology and complexity of infection confer difficulty in thoroughly eliminating microorganisms and their by-products in the root canal system, especially in the root apex area (including the top one-third of the root canal and periapical tissue), which is described as the hardest area to clean during endodontic treatment. Infection is difficult to remove entirely because the apex area is hard to approach using dental instruments and because of the existence of special morphological structures, such as apical ramification, intercanal anastomoses, and lateral branch of root canal. This review gives a brief introduction of the characteristics and difficulties of apical infection and knowledge on how to control such infections, including root apex preparation, irrigation and disinfection, and root canal filling.

Objective To explore the diagnosis and treatment of gastroparasis syndrome after abdominal operation. Methods Clinical data of 25 cases with gastroparasis syndrome after abdominal operation from Jan 1995 to June 2006 were analysed retrospectively. Results Gastrectomy and nongastrectomy amounted to 16 and 9 cases( portal-azygous vein disconnection in 4 cases, panceaticoduodenectomy in 1 case, partial small intestinectomy and adhesions lysis in 1 case, radical excision of colon carcinoma in 2 cases, choledocholithotomy in 1 case). Gastroparasis syndrome characterized by upper abdominal distension, nausea, vomiting after clipping the pipe or large quantity of gastric drainage after operations. Gastrointestinal series and gastroscopy confirmed functional delayed gastric emptying. All cases recoverd through non-operative therapy including fasting, continuous gastrointestinal decompression, total parenteral nutrition or enteral nutrition, adn administration of gastro-intestinal dynamic medicine. Conclusions Gastroparasis syndrome is the common complication after abdomianl operation, gastrointestinal series, gastroscopy are main diagnostic methods, conservative medication obtains good effect.

Objective To explore the effect on nutrient and immune function of glutamine-enriched enteral nutrition on patients after total gastrectomy. Methods 36 patients after total gastriecomy were randomly divided into EN(n=18) and GLN(n=18) group. Compared the index after total gastrectomy including nutrient status, immune function and lassitude degree in the 1st, 3rd, 7th day. Results GLN group showed more effective process than EN group in improving postoperative nutrient status, immune function, nitrogen balance and lassitude degree. All the indexes in GLN group changed significantly on the 7th day than that in EN group(P

Objective To explore the protective effect of Salvia miltiorrhiza on small intestinal ischemia reperfusion injury during intestinal transplantation induced by cytokines in rats.Methods Sixty Sprague Dawley rats were randomly divided into sham operation group,model group and low,mid,high doze treatment group,the superior mesenteric artery was occluded and then released to simulate the model of small intestinal ischemia reperfusion during intestinal transplantation.Tumor necrosis factor-?,interleukin-1?,interleukin-8 both in the plasm and small intestinal tissue were evaluated by ELISA 2 hours after reperfusion,changes of pathology in intestinal mucosa were observed.Results TNF-?,IL-1?,IL-8 were significantly higer(P
