[Objective]To compare the outcome and complication rates following nonoperative and those after ptate fixation of displaced midshaft clavicular fractures.[Method]Between March 2001 and December 2005,the data of 110 patients with a displaced midshaft fracture of clavicle were retrospective analyzed.Among them,62 patients were treated with plate fixation,including 53 male and 9 female patients aged 33.5 years old averagely.48 patients were treated with closed reduction and a figure-of-eight bandage applied,including 33 male and 15 female patients aged 33 years old averagely.Following enrollment in the study,the patients were seen at six weeks and at three,six,and twelve months.Assessment included standardized clinical evaluation,completion of the Constant shoulder score,complication and plain radiographs.Radiographic union was defined as complete cortical bridging between proximal and distal fragments on radiograph.[Result]All patients completed one year of follow-up.Constant shoulder score were significantly improved in the operative fixation group at all time-points(P

Objective To observe the effect of early intervention on the oligodendrocyte-myelin glycoprotein(OMgp) mRNA expression of brain injury neonatal rats caused by intrauterine infection.Methods 1.Twenty-eight Wistar pregnant rats were randomly divided into 2 groups:lipopolysaccharide(LPS)-treated group and saline control group.Pregnant rats were consecutively injected with LPS (450 ?g?kg-1) or saline on the 18th gestation age.After birth,the placentas were taken out and made HE staining to observe intrauterine infection.2.Thirty neonatal rats in the saline control group and 55 rats in the LPS-treated group were randomly selected which were divided into intervention group (n=25) and no-intervention group (n=25).The second post-natal day (P2) rats in intervention group were treated by early touch and enriched environment.The neonatal rats in the no-intervention group and saline control group were fed in a routine way.Five cases of P1 rats were selected respectively from the LPS-treated group and saline control group,and brain tissue pathological section was made to observe the condition of brain injury.3.Five cases of P1,P3,P7,P28 and P42 rats were selected from the saline control group,intervention group and no-intervention group to detect the OMgp mRNA expression levels by using the real time polymerase chain reaction me-thod.Results 1.There were a great number of neurophilic granulocytes in the placentas in the LPS-treated group.2.Brain tissue pathological of P1 in the saline control group had complete substantia alba structure,ordered disposition and lightly stained clear chromatospherite.While in the LPS-treated group, there existed brain tissue looseness,colloid cell aggregation and oligodendrocyte cytoreduction in the position of substantia alba,callositas and capsula interna.Intraventricular hemorrhage,substantia alba blood vessel dilatation and blood capillary angiorrhexis and hemorrhage could also be found.3.There was a higher increase in OMgp mRNA expressions of brain tissue in the LPS-treated group at P1,P3,P7,P28,P42 than those in the saline control group (Pa

Minichromosome maintenance protein 7 (MCM7) is an important regulator of DNA replication,and plays an important role in replication initiation and elongation steps.Recent studies show that MCM7 is closely related with the formation and growth of digestive tumors.The detection of MCM7 protein can provide new ideas for the early diagnosis,treatment and prognosis of the digestive tumors.

Objective To investigate the peripheral blood Th17 and CD4 + CD25 + regulatory T cell levels and their correlations in patients with primary hepatocellular carcinoma (PHC).Methods Peripheral blood samples were collected from 30 PHC patients and 25 healthy controls in the First Affiliated Hospital of Zhejiang University from June 2008 to May 2009.Mononuclear cells were isolated and the Th17 and CD4 + CD25 + regulatory T cells were detected by flow cytometry and compared between patients and controls by t test.Spearman test was performed to analyze the correlation of Th17 with CD4 + CD25 +regulatory T cell concentrations.Results The levels of Th17 and CD4 + CD25 + regulatory T cells in peripheral blood in healthy controls were (2.10 ± 0.87) ％ and (7.10 ± 2.32) ％ ; while those in PHC patients were (3.38±1.68)％ and (11.78±5.62)％ (t=3.640 and 4.162,P＜0.01).The level of Th17 cells was positively associated with that of CD4 + CD25 + regulatory T cells in PHC patients (r =0.821,P ＜0.01).Conclusion The levels of Th17 and CD4 + CD25 + regulatory T cells in peripheral blood are high in PHC patients and positively correlated with each other,which indicates that CD4 + CD25 + regulatory T cells may contribute to the disease progression and pathogenesis of carcinoma through inducing Th17 cells differentiation.

AIM: To investigate the expression of iNOS in the lung of HPS rats treated with tumor necrosis factor-? monoclonal antibody(TNF-?-McAb) and to investigate the therapeutic mechanism of TNF-?-McAb on hepatopulmonary syndrome.METHODS: Male Sprague-Dawley rats,weighing(250?25)g,were randomized to sham operation group,common bile duct ligation(CBDL) group and CBDL+TNF-? McAb treatment group.Histopathological changes of the lung tissue were evaluated by hematoxylin and eosin staining.The mRNA expression of iNOS in the lungs of hepatopulmonary rats was examined by RT-PCR,while the changes of iNOS in the protein level were evaluated by immunohistochemistry and Western blotting.RESULTS: The inflammatory responses in the CBDL rats treated with TNF-?-McAb decreased than that in CBDL group.Compared to CBDL group,the distribution of iNOS protein and the mRNA expressions in the lung tissue in TNF-?-McAb group were inhibited.CONCLUSION: TNF-?-McAb inhibits the expression of iNOS and plays a role in the treatment of HPS.
