Objective To investigate the role of nuclear factor-kappa B(NF-?B) and monocyte chemoattractant protein-1(MCP-1) in the pathogenesis of uric acid nephropathy.Methods Twenty male SD rats were divided into control group(group C) and model group(group M).The model rats with uric acid nephropathy were made using adenine.Immunohistochemistry was used to detect the expressions of NF-?B and MCP-1 in 18 days and the serum uric acid and renal fuction were measured respectively.Results In comparison with group C,the expressions of NF-?B and MCP-1 in the rats of group M were significantly increased(all P

Objective To summarize the clinicopathologic characters and the route of lymphatic metastasis of cancers at the gastroesophageal junction. Methods Clinicopathologic data of 86 cancer patients treated from October 2000 to December 2004 were analyzed retrospectively. Results There were 66 males and 20 females, the mean age was 60 years. Most patients were of Bormann typeⅢadenocarcinoma. The incidence of high differentiated adenocarcinoma in TypeⅠcancer was higher than that in other two types (P = 0. 002, P = 0. 004) , while the incidence of poor differentiated carcinoma in typeⅢcancer was higher than other two types(P = 0. 005 ,P = 0. 015). Metastatic rate of lymph nodes in group 1 and group 2(34. 9% ) .group 3 and group 4(36. 0% ), group 7 through to group 9(27. 9% ), group 10 and 11 (15. 1% ) was higher than in other groups, while that in group 5 and 6(11. 6% ) , and group 12(5. 8% ) was lower compared with other lymph nodes (P

Objective To summarise the clinicopathologic features and survival of gastric cancer at different tumor locations.Methods A total of 942 adult gastric cancer patients undergoing curative gastrectomy with lymphadenectomy were recruited from the First Affiliated Hospital,Sun Yat-sen University,and examined retrospectively.In all cases,patients' age,gender,pTNM stage and survival time were identified and recorded.Results There were 208 carcinoma cases at gastroesophageal junction (GEJ,22.1％),261 fundus/body cases (27.7％),445 antrum/pylorus cases (47.2％) and 28 whole stomach cases (3.0％).Compared with fundus/body and antrum/pylorus carcinoma,GEJ carcinomas were more often seen in males,among older patients,with larger tumor size and deeper infiltrated tumors,higher stage and worse 5-year disease-free survivals.Whole stomach carcinoma had predilection in female,younger patients,and at later stages and worst 5-year disease-free survival.Conclusions Gastric carcinomas differ greatly in biologic behavior and prognosis by anatomic locations.GEJ carcinoma has independent biologic features.Whole stomach carcinoma is of the highest malignancy and worst prognosis.

Objective To compare the feasibility and safety of pancreaticogastrostomy versus pancreaticojejunostomy after pancreaticoduodenectomy. Methods A retrospective study was performed on 37 patients who underwent pancreaticoduodenectomy for duodenal carcinoma or pancreatic head tumors at the First Hospital of Sun Yat-sen University from April 2006 to December 2010.Pancreatic anastomosis was carried out either using pancreaticogastrostomy (n＝ 19) or pancreaticojejunostomy (n=18).The operative time,intraoperative bHood Hoss,postoperative pancreatic Heak,mortaHity and Hength of hospitaH stay were compared between the two groups. ResuHts The mean operative time,intraoperative bHood Hoss,incidence of pancreatic fistuHa,mortaHity rate and mean Hength of postoperative hospitaH stay were (372.1 ±79.5) min vs (351.0±69.2) min; (693.5± 412.8) mH vs (645.1±488)ml; 10.5％ (2/19) vs 11.1％ (2/18); 5.3％ (1/19) vs 5.6％ (1/18); and (17.5± 8.9)d vs (16.1± 7.6)d,respectively.The differences between the two groups were not statistically significant.Conclusion Pancreaticogastrostomy appears to be a feasible and safe alternative to pancreaticojejunostomy for the pancreatic remnant after pancreaticoduodenectomy.

Objective To study the characteristics of the diseases spectrum in hospitalized children.Methods The items of main diagnosis,gender,age,etc.in the inpatients medical records home page data aged 0? 12 years old in second-level and above hospitals of Chongqing City during 2015 were performed the disease spectrum sequence and constituent ratio analysis for deeply digging the relation between the disease change trend with the age and sex.Results The top 5 main system diseases affecting children's health were respiratory system diseases (male 43.84％,female 45.74％),some conditions originated from prenatal period (male 12.01 ％,female 13.87 ％),infectious diseases and parasites diseases (male 9.48 ％,female 9.88 ％),digestive system diseases (male 9.09 ％,female 6.95 ％),injury,poisoning and some other consequences of external causes(male 6.86 ％,female 5.27 ％).Respiratory system diseases always ranked the first place,the sexual difference among various system disease was unobvious,the sequence of injury,poisoning and some other consequence of external causes was increased with the age increasing;in the ranking of respiratory system diseases,pneumonia(38.73 ％),acute bronchitis(17.29 ％) and acute tonsillitis(13.83％) were the top 3 diseases affecting children's health.Conclusion Respiratory system diseases are the concerned key point for children health promotion.The health and epidemic prevention departments should provide effective methods and measures for preventing respiratory system diseases in children.Furthermore,the targeted prevention and treatment measures should be proposed aiming at the difference of disease sequence in different age groups.

Objective To study the feasibility, safety and clinical effects of spleen and splenic vessel-preserving distal pancreatectomy. Methods A retrospective study was performed in 26 patients undergoing distal pancreatectomy for benign or low grade malignant disease with splenectomy (n = 13) or splenic preservation (n = 13 ) at the First Hospital of Sun Yat-sen University and Guangdong General Hospital from May 2002 to April 2009. Results All 26 pancreatectomy with splenectomy or splenic preservation were performed successfully. There was no statistically significant difference between two groups in average operative time[(172±47) min vs. (157±52) min, P ＞ 0.05 ], intraoperative estimated blood loss [( 183 ± 68 ) ml vs. ( 160 ± 51 ) ml, P ＞ 0.05 ], incidence of noninfectious and infection complication and postoperative hospital stay [(10.1±2.2) d vs. ( 12. 1 ± 4. 6 ) d, P ＞ 0.05 ]. The platelet counts examined one week after operation were significantly higher in the distal pancreatectomy with splenectomy group than that in spleen-preserving group [(37.3 ± 12.8)×109/L vs. (54.7 ± 13.2) × 109/L, P＜0.05 ]. Conclusions Spleen-preserving distal pancreatectomy appears to be a feasible and safe procedure in selected cases of benign or low-grade pancreatic malignant disease necessitating a distal pancreatectomy.

Objective To explore the correlation between serum miRNA-216a level and severity of acute pancretitis (AP) .Meth-ods 17 cases of mild acute pancreatitis (MAP group) ,23 cases of severe acute pancreatitis (SAP group) and 30 cases of healthy subjective (control group) were selected in our hospital from June 2015 to June 2016 .Blood amylase activity and serum miRNA-216a were detected ,Ranson value ,APACHEⅡvalue and modified CT severity index (MCTSI) were used to evaluate the severity of AP ,analyze the correlation between miR-216a level and other indexes .Results The serum amylase activity of MAP group and SAP group in acute stage were higher than those in convalescence in these groups and the control group (P<0 .05) ,and the serum amyl-ase activity in the acute phase SAP group was higher than that in the MAP group ,and the difference was statistically significant (P<0 .05) .The relative expressions of serum miR-216a in MAP group and SAP group in acute stage were significantly higher than those in convalescence in these groups and the control group (P<0 .05) ,and the relative expressions of serum miR-216a in SAP group was higher than that in the MAP group ,and the difference was statistically significant (P<0 .05) .The miR-216a expression was positively correlated with Ranson score ,APACHE score and MCTSI score (r=0 .667 ,P<0 .05 ;r=0 .396 ,P<0 .05 ,and r=0 .648 ,P<0 .05) .Conclusion The expression level of serum miR-216a of patients with AP was significantly higher than that of healthy people ,and the expression level of serum miR-216a was positively correlated with the severity of AP ,which was useful for the diagnosis and prognosis of SAP .
