Objective To explore the impact of transtheoretical model on sun protection behaviors of soldiers in plateau area.Methods A total of 208 male soldiers trained in 4 200 meters altitude and medically supported by our hospital were randomly divided into the experimental group(n=104) and the control group(n=104).The experimental group received health education based on the transtheoretical model,and the control group received routine health education.Score of sun protection behaviors questionnaire,sunscreen using behavior and score of the Dermatology Life Quality Index (DLQI) before and after the intervention between two groups were compared.Results Score of sun protection behaviors questionnaire in the experimental group was higher than that in the control group (P＜0.05),sunscreen using behavior in the experimental group was better than the control group(P＜0.05),score of the Dermatology Life Quality Index in the experimental group was lower than the control group(P＜0.05).Conclusion Health education guided by the transtheoretical model can improve the plateau soldiers' sun protection behaviors,and it is an effective method of health education.

Objective To systematically review the efficacy of ilaprazole in duodenal ulcer by Meta analysis.Methods Randomized controlled trial (RCT) comparing ilaprazole with other proton pump inhibitors in duodenal ulcer were searohed for Meta analysis.Results Six RCT met the inclusion criteria and 1319 patients were included.Meta analysis showed that the healing rate at 4-week in the dose of ilaprazole 10 mg/d was higher than that in control group [ 89.1％ (591/663 ) vs.86.4％ (426/493) ],but there was no significant difference (P＞ 0.05 ).When including high-quality literature,English literature,Chinese literature,or the literature using omeprazole as control,there was no significant difference either (P ＞ 0.05 ).The adverse rate in the two groups had no significant difference [ 9.7％ (64/663) vs.12.6％ (62/493)] (P ＞0.05 ).The 4-week healing rate between the doses of ilaprazole 5 mg/d and 10 mg/d had no significant difference [84.7％(138/163) vs.84.0％(131/156)](P＞0.05).Conclusions Ilaprazole has high healing rate for duodenal ulcer,with low adverse rate.The effect of the dose ot5 mg/d is comparable to 10 mg/d.

The conformity between bone implant and bone tissue plays an important role in osseointegration.Protein molecules such as extracellular matrix proteins,cytoskeletal proteins,and attachment proteins,which produced by osteoblasts,promote the attachment of osteoblasts to bone implant and the surrounding ceils.In vitro studies show that nano-plated implant material bears excellent biocompatibility and superior physical and chemical features.Nano-scale material has the advantage of high surface roughness,wettability and electrochemistry features which erdaance the adherence and interaction of extracellular matrix proteins and promotes the attachmerit,proliferation and differentiation of osteoblasts.The expression of cytokines,such as prostaglandin E2(PGE2)and transforming growth factor-β(TGF-β)are also increased in nano-structured bone implants which in turn promote the new bone formation.Further studies need to be done to explain the mechanism of the effect of nano-tructured bone implant on osteoblasts.

Objective To improve the diagnosis and treatment of inflammatory myofibroblastic tumor (IMT) of the urinary tract in pediatric.Methods The retrospective study of 12 IMT was based on information retrieved from Beijing Children's Hospital from January 2006 to July 2015.The literatures of urinary IMT were reviewed.There were 12 cases of urinary IMT, with 8 cases in bladder, 2 in kidney, 1 in ureter and 1 in prostate.Mean age at surgery was 6.4 years old (range 2months-13 years), 6 cases males and 6 females.Tumor resection were performed in 11 patients, biopsy was performed only in 1 patient.Results HE staining revealed diffuse appearing spindle myofibroblastic cells admixed with inflammatory cells.Immunohistochemistry showed positive ration for following markers as ALK (8/12), CK18 (6/12), Desmin (7/12), SMA (8/12), Actin (1/2), Vimentin (9/12).Negative staining were seen for Myoglobin, S-100 and Ki-67 ＜ 20％.Patients were followed up in 10 cases, lost to follow-up in 2;the mean follow-up time was 14.4 months (range 3-31 months).All patients recovered well without relapse or metastasis.Condusions Inflammatory myofibroblastic tumors of the urinary tract in pediatric were rare, without specific characteristic in clinical features and imaging.The main treatment of IMT is complete surgical excision.

Objective To compare the efficacy of different dose esomeprazole-based triplen therapies for Helicobacter pylori (Hp)eradication. Methods Two hundred and forty Hp-infected patients were randomly assigned to undergo high-dose (40 mg) or low-dose (20 mg) esomeprasole combined with clarithromycin (500 mg) and amoxicillin (1g) twice a day for one week. Hp eradication test was performed at 4 weeks after the end of treatment to evaluate the response to therapy. Results One hundred and fourteen patients were followed up in high-dose patients, and 104 were Hp eradication. One hundred and thirteen patients were followed up in low-dose patients, and 101 were Hp eradication. There was no significant difference in eradication rate of intention-to treat analysis and per protocol analysis between high-dose and low-dose patients [86.7%(104/120) vs 84.2% (101/120) and 91.2% (104/114) vs 89.4% (101/113), P>0.05]. There was no significant difference in the rate of adverse effect between high-dose and low-dose patients (8.3%(10/120)vs 6.7%(8/120), P>0.05). Conclusion It demonstrates that low-dose esomeprazole-based triple therapy has a similar Hp eradication rate compared with high-dose esomeprazole-based therapy in China.

Objective Cathepsin K (CTSK) played an important role in adipocyte differentiation.The activation of CTSK needs to convey by mannose-6-phosphate receptors (M6PR) in osteoclasts. The aim of the present study was to identify the effects of mannose-6-phosphate (M6P) in adipocyte differentiation and its underlying molecular mechanism. Methods Oil red O staining, accumulation of cytoplasmic triglycerides and glycerine release were used to assess its effects on adipocyte differentiation in the 3T3-L1cell line. The enzyme activity of CTSK was observed by laser confocal microscopy. The proliferation of 3T3-L1 preadipocytes was detected by MTT methods. mRNA expression of M6PR was determined by RTPCR. Results M6P could prevent adipocyte differentiation in a dose-dependent manner as evidenced by absence of triglyceride accumulation and glycerol content. Statistical significance was showed when the concentrations of M6P were 5.0 mmol/L and 8. 0 mmol/L respectively(P ＜0. 05). The mRNA expression of M6PR was detected during the whole process of adipocyte differentiation. With the increase of M6Pconcentration, enzyme activity of CTSK was inhibited in a concentration-dependent manner. MTT method showed that the absorbance at 570 nm of 3T3-L1 preadipocytes was 0. 057 ±0. 091, increased about 62. 9%at 10. 0 mmoL/L compared with the control group (P ＜ 0. 05 ). Conclusion M6P inhibits the terminal differentiation of adipocyte, which may be associated with its effect of blocking CTSK activity by competitive binding with M6PR.

Objective To investigate the experience of diagnosis and management of coexisting ureteropelvic junction obstruction (UPJO) and nonreflux megaureter (NRM).Methods The retrospective study of UPJO with NRM was based on 10 years information retrieved from January 2005 to December 2015.The data of 13 patients (8 males and 5 females) were available and recorded.Mean age at surgery was 3.7 years old (range 1.8 to 14 years).The diagnosis and mangement were summarized.Coexisting ureterovesical junction obstruction (UVJO) and vesicoureteral reflux,iatrogenic stricture and vesicoureteral reflux were excluded.Intravenous pyelography,voiding cystourethrography,ultrasound and CT reconstruction were performed before operation.Only six patients had an accurate diagnosis as UPJO with UVJO before surgery.Pyeloplasty was the initial surgical management choice for 10 patients,and ureteroneocystostomy in 3 patients.Results UVJO were diagnosed with pyelography techniques in 3 patients after pyeloplasty,while 4 were diagnosed as nonreflux and nonobstruction megaureter.Of the 10 patients who underwent initial pyeloplasty,additional ureteroneocystostomy was required in 3 and the prognosis was good.Additional pyeloplasty was required in 2 of the 3 patients who initially underwent ureteroneoeystostomy.Mean follow-up time from last operation was 23.3 months (6-53 months),the overall prognosis was good.Conclusions It is often difficult to correctly diagnose coexisting UPJO and NRM.In patients with UPJO,it is highly recommended nephrostomy radiography after pyeloplasty to evaluate the distal ureterovesical junction.Initial pyeloplasty is always recommended as first-line therapy.Additional ureteroneocystostomy was required when hydroureteropelvic was aggravated.

Objective To discuss the clinical and pathological features of malignant rhabdoid tumor of the ureter (MRTU).Methods One case of MRTU was reported, a six-year-old girl was admitted to our hospital on May 29, 2014, and presented left loin pain 2 weeks, ultrasound showed gradually progressing hydronephrosis and hydroureter.During a physical examination, she felt tenderness in the left kidney area and no mass was palpable in abdomen.The ultrasound showed left sided gross hydroureteronephrosis and a round hyperechogenic mass in the inferior pole of the left ureter (In front of the left iliac vessel), with no obvious borders.Contrast-enhanced CT suggested a gross dilatation of the left kidney and ureter with a solidappearing lesion in the lower ureter;neither additional abdominal abnormalities nor enlarged lymph nodes were seen in both examinations.The surgery began with incision of left lower abdomen.The partial ureter of neoplasm was excised along with invaded psoas and posterior peritoneum by gross inspection, then ureteroureterostomy was performed.The severed ureter was completely blocked with the ill-defined neoplasm and was 3.3 cm in length and 2.1 cm in width.Results The ureteral neoplasm was excised,along with the invaded psoas and posterior peritoneum,after that ureteroureterostomy was performed.HE showed the diffuse large round nuclei, vesicular chromatin, prominent nucleoli cells, and moderate amounts of eccentrically placed eosinophilic cytoplasm.Immunohistochemical studies were positive for cytokeratin, epithelial membrance antigen and vimentin, negative for INI1, METU hereby was confirmed.She underwent a chemotherapy regimen consisting of ICE, alternating with VDC.Four courses chemotherapy (3 months) later,CT scan suggested hematogenous metastasis of lung.The family refused further treatment and the patient died of systemic metastasis eight months after surgery.Conclusion MRTU was a rare and highly aggressive tumor with a poor prognosis.

Objective To investigate the clinicopathological features of primary hepatic lymphoma (PHL).Methods Data of 5 PHL cases treated at our hospital between 1998 and 2002 were retrospectively analyzed. Results The patients were all male with a mean age of 43 6 years. Abdominal pain and fever were the most frequent presenting symptoms. Four (80%) were positive for the hepatitis B virus antigen. Tumors were all removed surgically in the 5 patients. Pathologic examination revealed B cell lymphoma, T cell lymphoma and Hodgkin′s disease in 2, 2 and 1 patients, respectively. Moreover, coexistent tumors were incidentally discovered by histology in 2 cases. ConclusionThere seems to be a close relationship between hepatitis B virus infection and the development of PHL; PHL should always be considered in the differential diagnosis for patients presenting with mass lesions in the liver; Surgical resection whenever feasible should be attempted as a part of combination modalities.
