Objective To assess the ability of interleukin-1 beta (IL-1?) antibody and tumor necrosis factor alpha (TNF?) antibody to prevent postoperative abdominal adhesion formation in mice.Methods 60 BALB/c mice were randomly divided into four groups: normal saline group(n=15), anti-IL-1? group(n=15), anti-TNF? group(n=15),and anti-IL-1? combined with anti-TNF? group(n=15). After an identical peritoneal injury operation, mice were treated using intraperitoneally with either normal saline or corresponding antibody at the time of abdominal closure. The mice were killed 20 days after operation, the abdominal incisions and the development of intra-abdominal adhesions were observed. Adhesion scoring was based on an overall assessment of the extent,location, and type of adhesion.Results Anti-IL-1? combined with anti-TNF? group had significantly lower adhesion scores (0 84?0 19) than that in other groups(P

Objective To evaluate the value of treating chotestatic hepatitis with tolynicate and naphthylacetia acid,and Dansen Root rejected fluid.Methods All patients were divided into Control Group treated with Potassium magnessium aspartape,Glucurolactone etc,and Treating Group treated with tolynicate and naphthylacetia acid,and Dansen Root re- jected fluid;The change of clinical symptom,jaundice decreasing and recovery of hepatic function were observed respec- tively.Results The change of clinical symptom,jaundice decreasing and recovery of hepatic function of Treating Group were better,and there are significant difference (P

Objective To improve the pancreaticoenterostomy technique and drainage in panereatieoduodenectomy, so as to prevent postoperative pancreatic leakage. Methods One hundred and thirty-eight panereaticoduodenectomy cases underwent parachute continuous running suture of pancreaticojejunostomy and extra drainage of the anastomotic stoma. Results The average time of the double-deck continuous invaginated pancreaticoenterostomy was 11 minutes, and there was no pancreaticoenterostomy leakage in all cases, lntraoperative blood loss was 353±61 ml, the average hospital stay was 19.2 days. Pulmonary infection developed in 6 cases, three cases suffered from postoperative upper gastrointestinal bleeding due to stress ulcer, two cases from functional delayed gastric emptying. All these complications were cured by conservative treatment, and there was no mortality in these series. Conclusions The parachute continuous running suture of pancreaticojejunostomy and extra drainage has the advantages of easy performance, saving time and less complications, and is an effective way in the prevention of panereatieojejunostomy leakage.

Objective To study the length changes of the inferior glenohumeral ligament(IGHL) during shoulder abduction with MRI and 3D software.Methods Fourteen right shoulder joints of 14 healthy volunteers were evaluated in 7 isometric abduction positions(0?,30?,60?,90?,120?,150?,and 180?) using MRI scanning.3D shoulder models were reconstructed and the attachment points of the ligaments were located.The shortest ligament lengths were calculated between each origin and insertion in 3D space for each abduction position.Results During shoulder abduction,the 3D distance of AIGHL was found to elongate and attained the maximal length at 120? abduction(54.5 mm?3.0 mm)(P

ObjectiveTo study the effect of aprotinin and tumor necrosis factor alpha(TNF-α) antibody on preventing postoperative abdominal adhesion in mice.Methods96 BALB/c mice were randomly divided into 4 groups:normal saline group(n=24),aprotinin group(n=24),TNF-α antibody group(n=24),and aprotinin combined with TNF-α antibody group(n=24).After an identical peritoneal injury operation,all mice were treated intraperitoneally with normal saline , aprotinin,TNF-α antibody and aprotinin combined with TNF-α respectively at the time of abdominal closure .The mice were killed 20 days after operation,the abdominal incisions and the development of intraabdominal adhesions were observed.Adhesion score was based on an overall assessment of the extent,location,and type of adhesions .ResultsAprotinin combined with TNF-α antibody group showed significantly lower adhesion score and 2-3 grade adhesion(advanced significant adhesion) rate was lower than that of other groups(P<0.01).Conclusions The intraperitoneal administration of aprotinin and TNF-α antibody can inhibit postoperative adhesion formation.

Objective To investigate the highly-recognized job evaluation factors among the doctors from tertiary general hospitals and to establish a doctor-oriented job evaluation factor system for general hospitals followed with the reliability and validity analyses.Methods A questionnaire about the highly-recognized 23 job evaluation factors was launched among 791 doctors by the stratified sampling from six tertiary general hospitals in Beijing,and the factors were from a job evaluation model of tertiary general hospitals.Initial factor solutions were obtained by the principal components analysis of all evaluation factors and the main factors whose eigenvalues were over one were extracted as evaluation dimensions. Factor loadings were attained through Varimax and the factor whose factor loading was lower than 0.5 was eliminated.A reliability analysis by calculating Cronbachαcoefficient and a validity analysis with structural equation modeling were sequentially conducted on the job evaluation factor system.Results A doctor-oriented job evaluation factor system for general hospitals including 22 factors subject to 3 dimensions was established while the factor of job relevance was removed. The internal consistency coefficients of the dimensions were greater than 0.8 according to the calculation of Cronbachα, which showed a nice reliability. Several main indexes for evaluating the model fitting were all close to 0.9,which indicated a fair structural validity. Conclusion A doctor-oriented job evaluation factor system for general hospitals is established with fair reliability and validity,which could provide more references to the job evaluation of the doctors in tertiary general hospitals.

Objective To investigate the curative effects of the traditional surgical method of posterior pedicle Schanz screw fixa-tion with partially stripping injured paravertebral muscle in treating thoracolumbar fracture .Methods 52 cases with thoracolumbar fracture underwent posterior pedicle Schanz screw fixation to partially strip injured paravertebral muscle from January ,2010 to Jan-uary ,2012 .The patients were divided into partially stripping injured paravertebral muscle group (32 cases) and traditionally strip-ping injured paravertebral muscle group(20 cases) .The blood loss ,postoperative drainage ,kyphosis postoperative 3 d VAS scores , vertebral height correction rate ,Cobb angle correction ,Oswestry dysfunction indexes were copmared .Results Comparing with tra-ditionally stripping injured paravertebral muscle group ,the partially stripping injured paravertebral muscle group has better effect in transperative blood loss ,postoperative drainage and postoperative 3 d VAS scores ,the differences were statistically significant .But there was no statistical significance between the two groups in vertebral height correction rate ,kyphosis Cobb angle correction ,Os-westry dysfunction indexes .Conclusion Partially strip injured paravertebral muscle has less painful than traditional surgery does , being safe and effective with small invasion and easy to recover .

Objective To explore the significance of interleukin -35 (IL -35)in serum of patients with severe hepatitis.Methods Collected 39 cases of chronic hepatitis B(CHB)patients and severe hepatitis,and col-lected 19 cases of healthy control's(HC)peripheral blood at the same time.ELISA method was used to detect IL -35 levels.Results IL -35 in CHB and severe hepatitis group [(483.5 ±280.7)ng/mL and (277.9 ±248.7)ng/mL] were higher than HC group (50.5 ±47.8)ng/mL(t =2.089,3.303,P =0.044,0.002).In severe hepatitis group, the IL -35 levels in survivors group (305.3 ±301.2)ng/mL was higher than death group (78.7 ±33.2)ng/mL (P =0.012).IL -35 was positively correlated with ALT and AST,the correlation coefficient were 0.649 and 0.599. Conclusion IL -35 is involved in the pathogenesis of hepatitis B process,the low serum IL -35 levels in severe hepatitis patients may herald a bad prognosis.
