Objective:To review and compare the clinical features and treatment outcomes of oral and maxillofacial space infection (OMSI)between diabetic and non-diabetic patients.Methods:Clinical data of 43 diabetic patients with OMSI(simultaneoustly treated by blood sugar control)and 84 of non-diabetic patients with OMSI were reviewed,the clinical features and treatment outcomes were compared.Statistical analyses were conducted by T test,the chi square test and variance analysis.Results:Diabetic patients with OM-SI were older(P =0.000),had more spaces involved concurrently(P =0.035 )and had higher blood sugar at presentation(P =0.000).There was no significant difference between groups about the use and change of antibiotics,the incision times,hospital stay durition and the incidence of the complications.Conclusion:The prognosis of the diabetic patients with OMSI under the strict control of the blood glucose concentration has no significant difference from the non-diabetic patients with OMSI.Diabetic patients with OMSI have older age and more spaces involved,and special attention should be paid.

Objective To discuss and analyze the clinical relationships between the gene polymorphism of vitamin D receptor and adiponectin with the susceptibility of non-alcohol fatty liver disease(NAFLD).Methods One hundred and two cases of NAFLD were selected as the observation group,and other 100 healthy volunteers were selected as the control group.The gene polymorphism of vitamin D receptor and adiponectin in the two groups was detected,then the genotype distribution and allele frequencies of vitamin D receptor and adiponectin were compared between the two groups,then their relationship with the susceptibility of NAFLD was analyzed.Results The genotype distribution situation of vitamin D receptor BsmI site,adiponectin 45 and 276 sites had statistically significant difference between the observation group and control group(P＜0.05).The B allele frequency of BsmI site of vitamin D receptor in the observation group was far lower than that in the control group,and the allele frequencies of 45-T and 276-G of vitamin D receptor in the former were far higher than those in the latter,and the differences between the two groups were statistically significant(P＜0.05).The multivariate unconditional Logistic regression analysis showed that vitamin D receptor:bb genotype,adiponectin 45 locus:TT genotype and ALT,TG,complicating hypertension history and HOMA-IR all were the independent risk factors in NAFLD patients.Conclusion The genotype distribution of different sites of vitamin D receptor and adiponectin has obvious abnormality in the patients with NAFLD,and both are closely related with the NAFLD susceptibility.

Objective To study surface heparinization of small intestinal submucosa(SIS)and an- tithrombegenicity of beparinized SIS films with plasma initiation technique for the engineering vascular scaffolds. Methods The SIS films were grafted with heparin by hypothermia plasma initiation technique.The blood com- patibility of the modified SIS films was assessed by observing blood coagulation time in vitro and the long term pa- tency of hepafinized SIS vascular scaffolds directly under the circulation of blood.Results The hypothermia plasma initiation method could attach heparin onto the SIS surface,The water contact angle of SIS films modified with heparin was decreased while the surface free energy and hydrophilicity increased.The prothrombin time(PT),ac- tivated partial thromboplastin time(APTT)and thrombin clotting Time(TT)of the SIS films modified with heparin were prolonged obviously.Small caliber engineering vascular scaffold made of heparinized SIS films kept the patency for six weeks.Conclusion Heparin can be attached to SIS films by hypothermia plasma initiation technique.The modified surfaces provide good and persistent antithrombogenicity,and possess potent blood compatibility,

Objective To analyze the effect of health education on recurrence of acute pancreatitis in discharged patients. Methods All patients with acute pancreatitis accepted health education during the first hospitalization.92 patients were randomly allocated to the trial group and the control group.The trial group was kept on being treated with health education for 18 months after discharged form the hospital but the control group didn' t.Results The recurrence rate of trial group was 8.50% but the control group was 24.44%(P

Objective In order to extrapolate the respiratory dysfunction of patients in early stage of acute organophosphorus pesticide poisoning (AOPP),transpulmonary thermodilution technique was used in swine models of severe acute dichlorvos poisoning (SADP) to evaluate respiratory function.Methods Twenty healthy female swine were randomly divided into dichlorvos ( n =7 ),atropine ( n =7 ) and control (n =6) groups.In the dichlorvos group,the swine were administered with 80％ emulsified dichlorvos (100mg/kg) via the gastric tube toinduce SADP.In the atropine group,swinewere administered with dichlorvos,and 0.5h later,atropine was injected to obtain and maintain atropinization.The swine of control group were administered with saline solution instead.Arterial and venous blood samples were collected 0,0.5,1,2,4 and 6 hours after modeling for blood gas analysis and detecting acetylcholinesterase levels.Both extravascular lung water index (EVLWI) and pulmonary vascular permeability index ( PVPI ) were measured by using PiCCO (pulse indicator continuous cardiac output ). At the termination of the experiment,the animals were sacrificed and the lung wet/dry weight ratio was determined and histopathological changes of lung tissue were also observed under microscope.Results In the dichlorvos group,EVLWI and PVPI were substantially increased from 0.5 h to 6 h after modeling but PaO2/FiO2 decreased from 0-6 h after modeling.In the atropine group,EVLWI and PVPI increased initially,but then they decreased 1 h afterwards and PaO2/FiO2 was also gradually decreased from 0-1 h.In both dichlorvos group and atropine group,the EVLWI was negatively correlated with PO2/FiO2 and positively correlated with PVPI.Compared with the control group,the lung wet/dry weight ratio increased markedly in the dichlorvos group and mildly increased in the atropine group.Meanwhile,the histopathological changes of lung tissue were obvious in the dichlorvos group and mild in the atropine group.Conclusions SADP swine experienced substantial changes in respiratory function. EVLWI was a reliable and valuable indicator for evaluating respiratory function in the early stage of AOPP.

Objective To compare the application,safety and theraputic effect of local resection of early rectal tumours by transanal endoscopic microsurgery(TEM) and the conventional transanal excision(TAE).Methods The data of seventy-six patients who were treated by conventional transanal excision from January 2003 to July 2006 and fifty-three patients who were treated by transanal endoscopic microsurgery from September 2006 to February 2010 in Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were reviewed.Results Age,sex,tumour size,blood loss,postoperative hospital stay were similar in the two groups(P＞0.05).The median distance from the anal verge was significantly higher in the TEM group ( TEM/TAE =7.0/5.0 cm,P ＜ 0.01 ).The operation time was significantly longer in the TEM group (TEM/TAE =70.00/30.00 min,P ＜ 0.01 ).There was no operation-related mortality in both groups (P ＞ 0.05 ).Two patients in the TEM group developed postoperative haemorrhage,and one patient developed pulmonary infection and retention of urine respectively.There were two secondary haemorrhage cases in the TAE group.On median follow-up of 30 months,there was 7.8％ recurrence rate in the TEM group,compared with 23.2％ the in TAE group.Conclusions Transanal endoscopic microsurgery is a safe and effective mininally invasive surgical technique for the treatment of early rectal neoplasm.It has broader indication,and better theraputic effect than the conventional transanal excision.

Objective To elucidate the evaluation of therapeutic effects and surgical treatments of 45 cases of inflammatory bowel disease. Methods Clinical data of 45 cases with inflammatory bowel disease by surgical treatment in recent 6 years were retrospectively analyzed. Results Patients received emergency operation in 16 cases, Crohn' s disease in 9 cases, Ulcerative Colitis( UC) in 7 cases. Among 13 cases of Crohn' s disease, partial enterectomy occured in 6 cases, partial enterectomy and colectomy and anastomosis in 1 patient because of internal fistula, repair of ileal perforation in 1 case, laparoscopic ileocolic resection in 5 cases. Among 32 cases of UC, 25 cases underwent ileal pouch-anal anastomosis operation, 3 cases underwent ileostomy with total colectomy, and 4 cases only underwent ileostomy. Twenty- seven cases were cured by operation, 14 cases were improved and 4 cases died. Conclusion It is the key point to achieve successful operation that the corresponding operative modes for varied manifestations of inflammatory bowel disease should be adopted.

Objective To investigate the roles of transforming growth factor(TGF)-β1 gene polymorphisms in severe acute respiratory syndrome-coronavirus(SARS-CoV)infection and the interstitial lung fibrosis after recovered.Methods Sixty-five recovered SARS patients,37 health care workers and 66 healthy controls were enrolled in this case-case study.The association between genetic polymorphisms of TG F-β1 and suscept ibility to SARS or interstitial lung changes after SARS reco,vered was carried out.Polymerase chain reaction-sequencing based typing(PCR-SBT)method was used to determine the polymorphisms of TGF-β1 gene at locus+869 and+915.Data were analyzed using t test and chi square test.Results There was no significant association of TGF+β1 gene polymorphisms at locus+869 and+915 in recovered SARS patients,health care workers and heahhy controls.And gene linkage of this two loci was not related with SARS-CoV susceptibility.Furthermore,no association between interstitial lung changes in recovered SARS palients and TGF-β1 gene polymorphisms or genetic linkage of this two loci.Conclusions It may not be related between TGFβ1 gene polymorphisms at locus+869 and+915 and SARS-CoV susceptibility.And interstitial lung changes in recovered SARS patients may not be influenced by TGF-β1 gene polymorphisms.

Objective To investigate relationships between serum levels of anti?tyrosinase IgG antibody(TYR IgG)as well as anti?tyrosinase?related protein?1 IgG antibody(TRP?1 IgG)and vitiligo. Methods Enzyme linked immunosorbent assay(ELISA)was performed to detect serum levels of TYR IgG and TRP?1 IgG in 260 patients with vitiligo and 50 health controls. The threshold for defining a positive test result was set at 3 standard deviations above the mean serum level of TYR IgG or TRP?1 IgG in the healthy controls. Results The positive rate of TYR IgG and/or TRP?1 IgG in the vitiligo group was 57.31%(149/260). The positive rates of TYR IgG and TRP?1 IgG were both significantly higher in the vitiligo group than in the control group(TYR IgG:37.3%[97/260]vs. 0,χ2=25.441, P<0.01;TRP?1 IgG:33.5%[87/260]vs. 0,χ2=21.630, P<0.01). The positive rate of TYR IgG was not associated with that of TRP?1 IgG in the vitiligo group(r=-0.032, P>0.05). Among patients with vitiligo, the positive rate of TRP?1 IgG was significantly higher in females than in males(χ2=5.811, P<0.05), as well as in patients aged≤20 years than in those aged>20 years(χ2=6.498, P<0.05), while the positive rate of TYR IgG didn′t differ between females and males, or between patients aged ≤ 20 years and those aged > 20 years (both P >0.05). Conclusion Detection of TYR IgG and TRP?1 IgG may provide some evidence for the diagnosis and treatment of vitiligo.

Objective To evaluate the efficacy and safety of telbivudine for pregnant women with hepatitis Be antigen (HBeAg)negative chronic hepatitis B(CHB). Methods Sixty-two cases of HBeAg negative CHB pregnant women were collected from May 2007 to May 2012,and they were divided into telbivudine group (n=31 ,600 mg per day by oral administration)and compound glycyrrhizin group (n=31 ,120 mg per day by intravenous administration).All neonates were given intramuscular injection of 200 IU hepatitis Bimmune globalin at birth immediately and 15 days after birth,and 20 μg genetically engineered hepatitis B vaccine at 0,1 and 6 months after birth.The serum alanine aminotransferase (ALT)level and hepatitis B virus (HBV)DNA titer were monitored.The HBV DNA negative conversion rate,the rate of intrauterine infection,duration of pregnancy,delivery mode,neonate weight and disability rate were compared between groups.All categorical data were analyzed using the chi-square test and comparison between groups was analyzed by t test.Results In telbivudine group,the HBV DNA level before delivery ([0.20±0.11]lg copy/mL)and 6 weeks after delivery ([0.22±0.13]lg copy/mL) were lower than that before treatment [(6.24±0.75 )lg copy/mL]and the differences were statistically significant (t=303.128 and 301 .321 ,respectively;both P <0.01).The negative conversion rate of HBV DNA in telbivudine group was 28 cases before delivery,while in compound glycyrrhizin group,no one had HBV DNA negative conversion.And statistical significant differences were achieved between these two groups before delivery and 6 weeks after delivery (t = -20.285 and -8.721 ,respectively;both P <0.01).In telbivudine group,the ALT levels before delivery and 6 weeks after delivery were (13.08±5.87) U/L and (25.97 ± 17.48)U/L,respectively,which were significantly decreased compared with that before treatment (205.95± 95.69 )U/L.The differences were statistically significant (t = 93.128 and 81.321, respectively;both P <0.01).In compound glycyrrhizin group,the ALT level before delivery ([104.15 ± 69.15]U/L)was lower than that before treatment ([209.60 ± 102.24]U/L)and the difference was statistically significant (t = 9.281 ,P =0.032).However,the ALT level was fluctuant 6 weeks after delivery (150.26± 86.43)U/L,which was not significantly different from that before treatment (t =2.821 ,P =0.122).The ALT levels before delivery and 6 month after delivery were significantly different in both two groups (t=-2.559 and -3.158,respectively;both P <0.05 ).There were no statistically significant differences between these two groups in the rate of intrauterine infection, duration of pregnancy,delivery mode,neonate weight and disability rate.Conclusion The using of telbivudine for pregnant women with HBeAg negative CHB can effectively control the hepatitis activation and reduce the virus titer.
