Objective To observe the clinical efficiency of nasal jejunal nutrition in children with acute pancreatitis and explore the effective nursing. Methods The clinical characteristics of 116 children with acute pancreatitis from February 2013 to May 2015 in our medical center were retrospectively analyzed. Based on nutritional support, the patients were divided into two groups: the control group consisted of 58 patients receiving oral feeding after the recovery of bowel function, and the experiment group consisted of 58 patients with nasal jejunal nutrition. And all the patients were treated with special care on case-by-case. The efficiency was then compared between the two groups. Results Compared with the control group, the length of hospital stay, cost of care, the incidence of complications, the surgical proportion and the mortality were significantly decreased in the experiment group (P<0.05). Conclusion In the children with acute pancreatitis, application of nasal jejunal nutrition is more effective, leading to decrease incidences of complications and surgical proportion, shorten the length of hospital stay, reduce patients' cost, and finally help rehabilitation.

Objective To construct a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem) and establish a nude mouse model of breast cancer with hepatic metastatic. Methods A gemcitabine-resistant variant of the breast cancer 4T1 cell line was induced by gradually increasing the concentration of gemcitabine; this variant is referred to in this study as 4T1/Gem. The proliferation suppression rates of 4T1 and 4T1/Gem cells were determined by using the CCK-8 essay to evaluate the drug resistance indices of the cell lines. Western blot analysis was used to detect P-gp protein expression. Under ultrasonography, a 4T1/Gem cell suspension was injected into nude mice to induce liver tumors. H&E staining was used to observe tumor pathology, and immunohistochemistry was used to detect the expression of ER, PR, HER-2, Ki-67, and P-gp. Results After 14 months of induction, a 4T1/Gem cell line is established successfully. The cell line can grow stably in culture liquid containing 40 μg/ml gemcitabine. The drug resistance index of 4T1/Gem is 788.547. Compared with the 4T1 cell line, the 4T1/Gem cell line can upregulate P-gp protein expression and successfully establish a nude mouse model of breast cancer with hepatic metastatic. ER, PR, and HER-2 proteins exhibit negative expression in the tumor tissue. The positive expression of P-gp and 10% of Ki-67 proteins is also observed. Conclusion This study successfully constructs a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem)and establishes a nude mouse model of breast cancer with hepatic metastatic, thereby providing an experimental basis for developing and treating a drug-resistant variant of breast cancer.

Methods 364 patients with reflux esophagitis were enrolled in our hospital from Jan to Dec in 2010.The severity grade of reflux esophagitis was according to Los Angles standard. All the patients received biopsies from gastric antrum,then received pathologic examinations. Results Reflux esophagitis in men was more common, with an average age of onset earlier than the female(52.4±11.6 years vs 56.6±12.4 years,P=0.002);Reflux esophagitis in patients with H.pylori infection rate was 90.9% overall,mainly with mild infection,four groups of H.pylori infection rate and extent of infection was no significant difference (P values were 0.419,0.702);reflux esophagitis in patients with chronic superficial gastritis(CSG),moderate active inflammation based was more common,there was no statistically significant difference in four group(P values were 0.146,0.496). There was no significant difference between H.pylori positive patients and H.pylori negative patients in esophageal mucosal damage(P> 0.05). There was no significant difference in reflux esophagitis with varying degrees of H.pylori infection on the degree of esophagitis. Conclusion Four groups of H.pylori infection rate and extent of infection was no significant difference; there was also no significant difference between H.pylori positive patients and H.pylori negative patients in esophageal mucosal damage.

Objective To investigate the diagnosis and treatment of primary splenic tumor. Methods The clinical data of 58 patients with primary splenic tumor from January 2006 to December 2014 were retrospectively analyzed. Results 45 cases were benign splenic tumor, including 21 hemangioma, 11 splenic cyst, 8 lymphangioma, 3 littoral cell angioma, 1 hamartoma and 1 sclerosing angiomatoid nodular transformation of spleen. 13 cases were malignant splenic tumor, including 12 lymphoma and 1 angiosarcoma. Ultrasound and CT were the main diagnostic methods. 51 cases underwent splenectomy, including 23 open splenectomy and 28 laparoscopic splenectomy. 5 cases underwent partial splenectomy and 2 splenectomy combined distal pancreatectomy. There had no postoperative complications. The follow-up period was 9 months to 9 years. 41 cases with benign splenic tumor had no recurrence or metastasis. The 1-, 3-, 5-years survival rate were 81.8%, 63.6% and 27.2% respectively of 11 patients with malignant splenic tumor. Conclusion The diagnostic of primary splenic tumor mostly rely on clinical features and imagic examination. Surgical resection is not only an effective treatment, but also a confirmed diagnosis method for primary splenic tumor. Partial splenectomy is a reasonable procedure for local benign splenic tumor. Early surgery, combined adjuvant chemotherapy and radiotherapy are important for improving the prognosis of malignant splenic tumor.

Objective To compare the clinic research between biliary stent insertion drainage and T-tube drainage after choledochotomy. Methods The clinical data of 90 cases from 2012 to 2014 were analyzed in a prospectively randomized trial, and they were divided into two groups by T-tube drainage and biliary stent insertion drainage. Cathetering and suture time, length of stay, hospital costs, life quality and incidence of complications were compared, respectively. Results After open common bile duct exploration (OCBDE), the life quality of stent group was significantly higher than that of T-tube group, the length of stay in stent group was shorter, and cathetering and suture time of bile duct in stent group was longer than that of T-tube group (P＜0.05); There were no significant differences between the two groups in the hospital costs and incidences of postoperative complications including bile leakage, early stent dislodgement, biliary infection, pancreatitis and residual stone (P＞0.05). Conclusion Endoscopic retrograde biliary drainage (ERBD) with primary closure after choledochotomy is a safe, effective and feasible procedure for the management of choledocholithiasis, it can significantly reduce the postoperative hospital stay and improve the life quality of patients and expand the indications for primary closure of CBD incision.

Objective To observe the efficacy and recurrence rates of mycophenolate mofetil (MMF) on hormone-dependent or steroid-resistant adult minimal change disease (MCD). Methods We retrospectively reviewed the records of adult patients at Shunde district hospital of traditonal Chinese medicine of Foshan for minimal change from February 2011 to August 2013. All patients who were hormone-dependent or steroid-resistant were collected. Twenty-five patients were randomly divided into short or long course group. The patient at short course group was given MMF combined with oral prednisone for 6 months, and the long course group was given for 18 months. Patient demographics, efficacy of medicines and recurrence rates were observed. Results Except one case of the long course group quitting at the second month because of severe infection, the other cases all finished the 18 months of follow up. At the 6 month after therapy with MMF, in both group, the 24h urine protein had lowered significantly (P<0.05) and the serum albumin level had risen remarkably (P<0.05). At the end of the follow up, compared with the 6 month after therapy, the 24 h urine protein of the short course group had increased (P<0.05), while those of the long course group had no obvious difference (P>0.05). At the 6 month after therapy, there were 9 cases achieved complete remission.There was no significant difference between the two groups (χ²=0.372, P>0.05). At the end of the follow up, compared with the 6 month after therapy, there were 6 cases experienced relapse (54.54%) in the short course group and 2 cases of those in the long course group (18.18%), but with no significant difference between them (χ²=0.076, P>0.05). Conclusion MMF can induce the remission of adult MCD efficiently, and its low dose maintenance treatment can decrease recurrence rates.
