ObjectiveTo investigate the efficacy and safety of the self-expandable metal stent for treatment of gastric outlet and duodenal obstruction.MethodsData of 24 patients with symptomatic gastric outlet and duodenal obstruction diagnosed from January 2005 to February 2011 were retrospectively studied.All patients were measured by gastric outlet obstruction scoring system ( GOOSS ) before and one week after the placement of self-expandable metal stent.ResultsStent placement was succeeded in all patients with a mean operation time of 25.90 ± 11.03 min.Twenty patients (83.3％) were able to intake liquid food after the procedure.The GOOSS (P50 =0) before and after stent placement were 0.14 (P50 =0) and 1.42( P50 =2),respectively,with significant difference (P ＜0.01 ).Minor digestive bleeding occurred in 3 patients,but no severe complications including perforation or aspiration were observed.ConclusionPlacement of a self-expandable metal stent in patients with gastric outlet or duodenal obstruction is safe and effective for resolving obstructive symptoms.

Objective To investigate the analysis of low calcium intravenous calcium supplementation agent and active vitamin D3 on total thyroidectomy on quality of life in patients with nodular goiter. Methods 40 cases of nodular goiter with total thyroidectomy were performed in our hospital from March 2014 to September 2016. It was randomly divided into control group and experimental group, 20 cases in each group. The patients in the control group were nodular thyroidectomy and the experimental group underwent total thyroidectomy. The quality of life of two groups of patients was evaluated by using the European five-dimensional health-related living quality scale (eq-5d). Results Two groups of patients, relevant questionnaire survey of the patient's ability to act, self-care ability, daily activity ability, pain or discomfort, anxiety, or depression, and the comparison of VAS score, according to the results of difference was not statistically significant. In comparison with ordinary people, the questionnaire survey results showed that the proportion of patients with moderate or above differences was higher and the difference was significant (P< 0.01). There was no statistical significance compared to the average person. Conclusion All patients with nodular goiter are treated with total thyroidism, and the effect is good, and the quality of life of patients is relatively small.

Objective To investigate the expression of podoplanin,?-catenin and vascular endothelial growth factor receptor-3(VEGFR-3) in lymphatic vessels of human esophageal squamous cell carcinoma(ESCC) tissue and the normal tissues adjacent to the carcinoma,and explore the markers which can specifically show the lymphatics with metastasis.Methods 63 surgical specimens of esophageal squamous cell carcinoma and 20 normal tissue specimens were obtained and examined.Immunohisochemical measures were employed to detect the expressions of podoplanin,?-catenin and VEGFR-3.The difference in expression of VEGFR-3 between ESCC tissue with lymphatic metastasis and the tissue without metastasis was statistically assessed.The lymphatic microvessel density(LMVD) positively stained by podoplanin was observed and counted under microscope with ?200 magnification.Results Based on the morphological characters of lymphatic vessels and capillary vessels observed under microscope,it was confirmed that podoplanin(positively stained as yellow-brownish discontinuous lines) expressed only on the cellular membrane of endothelial cells of lymphatic and microlymphatic vessels.VEGFR-3 was positively expressed in the endothelial cells of lymphatic vessels as well as vessel wall and the cytoplasm of carcinoma cell.There existed a significant difference in VEGFR-3 expression between the ESCC tissue with lymphatic metastasis and the tissue without metastasis,and the positive rate was 68.57% and 28.00%,respectively(P

Objective To investigate the epidemiologic characteristics of injuries of children aged 0 ~14 yrs. Methods Described analysis was used to analyze the epidemiologic characteristics about the age, gender, injury type and cause in children 0~14 years old who visited in emergency department of hospitals form 2006 to 2007. Results During the study period, 16 124 injured children were collected. the rank of injuries type were contused/abrased wound (44.41%), open injury (36.10%), sprain (12.81%), bone fracture (3.25%) and burn/scald injury (1.49%); the cause of injuries were fall down (55.24%), animal injury (21.49%) , blunt injury (8.47%) and traffic injury (6.96%); The common place of injury occurred were at home (53.66%), public and resident place (18.01%), road/street (11.73%) and school (10.70%). The gender ratio was 1.94, the median age was 6 years, the male injury was decrease with the age increase, but so wasn't the female. Conclusion Injury gradually becomes the key health problem and influences the children health. The effective measures should be taken in term of the epidemiology characteristics of the injuries among children at 0-14 to prevent and control injury occurring. The health education of preventing injury occurring and behavior drawback should be conducted as early as possible to raise awareness of injury issues among children in the kindergartens and promote them growing healthily.

ObjectiveTo investigate the development of apoptosis during ischemia/reperfusion (IR) injury and acute rejection, and to explore the significance of apoptosis in the Graft Mesenteric Lymph Node (GALT) in a rat heterotopic small bowel transplant (SBT) model.MethodsSBT was performed in F344/N rats with either freshly harvested or preserved (4 h, in ringer lactate solution at 4 ℃) syngeneic and allogeneic (Wistar/A-F344/N) grafts. Bowel and GALT samples were collected 2 h after reperfusion and on small bowel transplant postoperative days (POD) 1, 4, and 7. Histopathology assessment of the graft and GALT were prepared for hematoxylin-eosin (H&E) staining. Apoptosis was detected by the TUNEL and the electron microscope. ResultsThe number of apoptotic cells 2 h after reperfusion increased profoundly in association with preservation. After a significant decrease on POD 1, the apoptotic cells rose again between POD 3 and 7 only in allogeneic grafts. On the other hand, the apoptotic cells in allogeneic GLAT markedly increased from POD 1 to day 3; at that time point, neither histological findings of rejection nor increase in apoptotic crypt cells were present in the graft jejunum. ConclusionIR injury and acute rejection may both induce extensive apoptosis. The graft jejunum distinct second increase in apoptosis may be an early and specific sign of acute rejection. Apoptosis of GLAT cells was well correlated with and ahead of progression of acute rejection.

Objective To explore the safety and efficacy of endoscopic retrograde cholangiopancreatography(ERCP)by using carbon dioxide for malignant biliary obstruction.Methods A total of 60 patients with malignant biliary obstruction, hospitalized from September 2008 to February 2010, were randomly divided into 3 groups to receive ERCP by using carbon dioxide, contrast agent or magnetic resonance cholangiopancreatography(MRCP)without any agent.The safety and efficacy of 3 contrast methods were compared.Results Successful stent or drainage tube insertion was achieved in all patients.Carbon dioxide was superior to contrast agent in terms of lowering postoperative infection rate(P ＜ 0.05), and it was also superior to MRCP for more effective drainage(P ＜ 0.05).There was no significant difference in occurrence of postoperative pancreatitis and hyperamylasemia between 3 groups.Conclusion Using carbon dioxide during ERCP, safe and effective, is superior to use of contrast agent in less leukocyte increase, and to MRCP in more adequate drainage in patients with malignant biliary obstruction.Furthermore, there is no more risk of pancreatitis and hyperamylasemia.

Objective To investigate epidemiological and clinical features of patients with clonorchiasis sinensis infection. Methods The epidemiological, clinical, laboratory and treatment data of clonorchiasis patients in Department of Infectious Diseases, Second Affiliated Hospital, Harbin Medical University from 2002 to 2004 were retrospectively analyzed. Results Sixty-eight point two percent patients had a history of eating raw freshwater fish and shrimp. Patients with occupations as cook, fish stock man, fishing man and fishmonger accounted for 22.6%. The transmission route was not clear in 9.1% of patients. The common clinical manifestations were abdominal pain (60.3%), fatigue (52.3%), diarrhea (33.0%), anorexia (69.3%), jaundice (23.9%), hepatomegaly (59.1%), splenomegaly (8.0%), dizziness (20.9%), fever (5.7%) and biliary colic (14.8%). Twenty-eight point four percent were asymptomatic. Other findings included liver dysfunction (70.4 %) and eosinophile granulocyteosis(69.3 %). Negative rate of stool egg of clonorchis sinensis after treatment with praziquantel or albendazole was 91.9% or 86.5%, respectively. There was no significant difference between the two groups ( χ2 = 0.561, P = 0.454). Conclusions Clinical manifestations of patients with clonorchiasis sinensis are complicated and often accompanied with liver dysfunction. Clonorchiasis sinensis is often misdiagnosed and should be paid much attention.

Objective To investigate the value of dynamic contrast-enhanced magnetic resonance imaging ( DCE-MRI) in differentiating serological negative early stage rheumatoid arthritis (RA) from osteoarthritis (OA)in hand. Methods Plain MRI, enhanced MRI of whole hand and DCE-MRI of single slice were performed in 53 patients suspected of RA or OA and 18 healthy volunteers. Twenty-three of them were diagnosed as RA,including 18 cases of serological negative RA and 18 of them were diagnosed as OA after 3 to 6 months follow-up. The contrast rate,slope, thickening of synovial membrane were measured on DCE-MRI in three groups and the MRI findings were also were detected in both RA and OA groups. The contrast rate and slope of synovial membrane were compared among three groups using rank sum test. The thickening of synovial membrane were compared among three groups using variance analysis. MRI signs of RA and OA group were evaluated with rank sum test Results The dynamic contrast rate of synovial membrane in RA group,OA group and control group was(100.78±61.96)%,(40.44±15.43)% and (23.56±9.14)%,respectively.Individually,RA group to OA group,u=3.101,P=0.002;RA group to control group,u=4.669,P=0.000;OA group to control group,u=3.482,P=0.000.The slope of contrast curve of synodal membrane of RA group,OA group and control group was 72.50°±13.34°,45.39°±9.94°,14.56°±5.75°,respectively.Individually,RA group to OA group,u=8.002,P=0.000;RA group to control group,u=17.102,P=0.000;OA group to control group,u=9.100,P=0.000.The synovial membrane thickening of RA group,OA group and control group was(3.3±0.5),(2.8±0.7)and (1.4±0.6)mm,respectively.Individually,RA group to OA group,q=2.622,P=0.011;RA group to control group,q=9.583,P=0.000;OA group to control group,q=6.961,P=0.000.Conclusion The quantitative index of DCE-MRI,including contrast rate and synovial membrane thickening may provide useful information for differentiating OA from semlogical negative early stage RA.The contrast rate and thickening of synovial membrane in RA group are higher than those in OA group.Many signs of MRI Can help differentiate OA from RA.
