Objective To compare the Occurrence rate of unplanned extubation(UEX)and anastomotic leakage by two different gastric tube for gastrointestinal decompression in patients after the operation of esophageal carcinoma.Methods Three hundred and eighty patients were randomly divided into two groups,the experimental group(n=90),ballonet gastric tubes were used;the control group(n=90),general gastric tubes were used.The occurTence rate of unplanned extubation(UEX)and anastomotic leakage were investigated.Results There was a remarkable difference(P＜0.01)in the rate of UEX between the experimental group and the control group.Though no statistical difference was seen in the rate of anastomotic leakage(P＞0.05),lower incidence of anastomofic leakage was seen in the experimental group.Conclusions BalIonet gastric tube for gastrointestinal decompression in patients after the operation of esophageal carcinoma can reduce the rate of UEX,improve the nursing qualiy and also successfully reduce the rate of anastomotic leakage.

BACKGROUND:In the fluorine-containing acidic environment, it is unclear whether Damon copper- nickel-titanium arch wire can have a corrosion resistance similar to conventional nickel-titanium arch wire and whether copper ion wil affect its corrosion resistance. OBJECTIVE: To evaluate the corrosion resistance of 3M nickel-titanium arch wires and Damon copper-nickel-titanium arch wires in artificial saliva with different fluoride and pH. METHODS:Potentiodynamic polarization curves of 3M nickel-titanium arch wires and Damon copper-nickel-titanium arch wires were measured in four kinds of artificial saliva (pH=7; pH=7, 0.2% fluoride; pH=7, 0.5% fluoride; pH=5, 0.5% fluoride). Then, the corrosion potential, corrosion current density and polarization resistance were acquired, and scanning electron microscope was used for morphological observation after corrosion. RESULTS AND CONCLUSION: In neutral (pH=7) artificial saliva, 0.2% fluoride ions added could shift up the Damon specimen polarization curve, increase the corrosion cerrent density and reduce the polarization resistance (P < 0.05); under the scanning electron microscope, corrosion was observable on the specimen surface. But 3M specimen polarization curve did not move, corrosion current density and polarization resistance substantialy unchanged (P > 0.05), and no significant corrosion was produced. When fluoride concentration was increased to 0.5%, the polarization curves of two kinds of the specimens moved, the corrosion cerrent density increased, the polarization resistance decreased (P < 0.05), and there was significant presence of corrosion on the specimen surface. When pH=5, corrosion phenomenon was more pronounced. These findings suggest that low concentrations fluoride cannot affect corrosion resistance of 3M arch wire, but can reduce the corrosion resistance of Damon arch wire; high concentrations of fluoride and acid can both reduce their corrosion resistance. In addition, the corrosion resistance of 3M arch is stronger than that of Damon arch wire.

Objective To explore the effect and side effects of Group A Streptococcus Preparation(Sapylin)com-bined with mitomycin and lentinan combined with mitomycin in treating malignant pleural effusion through intrapleural catheter.Methods 70 malignant pleural effusion patients were selected in this study.All the patients were randomly divided into Sapylin group and lentinan group.One case with penicillin positive of the Sapylin group was adjusted to enter the lentinan group.After drainage of pleural effusion,the patients were divided into Sapylin group (34 patients) and lentinan group (36 patients).For the Sapylin group,Sapylin was prior injected and mitomycin was posterior injected.For the lentinan group,lentinan was prior injected and mitomycin was posterior injected.The side effects and clinical effect were observed and reported.Results The effective rate of Sapylin group was 85.3%,whereas 83.3%of lentinan group.There was no significant difference between the two groups(χ2 =0.051,P =0.822).Both groups had the following minor side effects:chest pain,fever,vomit and decreased white blood cells.No liver or renal injuries were reported.Conclusion The clinical outcomes of Sapylin combined with mitomycin and lentinan combined with mitomycin are both positive,in addition,the side effects are minor.

Objective To approach a simple identification method for clinical Burkholderia cepacia isolates.Methods Thirty eight clinical isolates and 5 referenc strains were identified by phenotypic and genotypic methods. A simple method presented here included TSI agar, oxidase test, pigmentation test, catalase test and antibiograms.Results All but one B. cepacia isolate identified by phenotypic and genotypic methods were identified correctly by our method. One non B. Cepacia isolate identified by the genotypic method was identified as Burkholderia spp. by phenotyic and our methods.Conculsion The method we presented here was simple, practical for identification of clinical B. cepacia isolates.

OBJECTIVE To report a case of AIDS associated with penicilliosis marneffei and discriminate the morphology in bone marrow examination and cultural characteristic of Histoplasma capsulatum and Leishmania donovani.METHODS The three pathogens in bone marrow morphology and cultural characteristic were studied.RESULTS AIDS patient was often infected with P.marneffei,but we could differentiated easily from other pathogens because of its breeding by splitting up and the characteristis structure in bone marrow examination.CONCLUSIONS Isolation of the P.marneffei is the golden diagnosis standard,and the examination of bone marrow is important to diagnose P.marneffei infection.

Medical consumables is the indispensible material foundation for diagnosis and treatment in hospital.The management of medical consumables is rather complicated for the multiplicity of its manufacture factories,suppliers and marketing ways.ISO9001 certification is extensively applied to the management of medical consumables,which can effectively ensure the consumables quality,prevent medical accident and protect consumer's privilege.

Objective To investigate the correlation between hemorrhagic transformation (HT) and each parameter of blood pressure variability (BPV) in patients with massive cerebral infarction caused by cardioembolic middle cerebral artery occlusion. Methods The patients with massive cerebral infarction caused by unilateral cardioembolic middle cerebral artery occlusion admitted to hospital within 24 h after onset were selected. For patients without revealing HT with head MRI on admission were analyzed retrospectively. According to the results of MRI rescan within 7 days after onset, they were divided into either a HT group or a non-HT group. Al specific parameters of blood pressure were compared and analyzed between the 2 groups, specificaly including initial value (initial), mean value ( mean), maximum value (max), minimum value (min), maximum-minimum difference (max-min), standard deviation (sd), successive variation (sv), and maximum value of sv (svmax) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results A total of 146 patients were enroled in the analysis, and 77 (52. 7% ) had HT within 7 d after onset. Al the blood pressure parameters were grouped by quartiles. Multivariate logistic regression analysis showed that after adjusting for age, admission time, baseline National Institutes of Health Stroke Scale score, congestive heart failure, antiplatelet therapy, initial blood glucose, prothrombin time, and international normalized ratio of the patients, SBPmin , SBPmax-min , SBPsv , SBPsvmax , DBPinitial, DBPsd , DBPmax , DBPmax-min , DBPsv , and DBPsvmax had significant independent association with and HT (likelihood ratio test of trend, al P < 0. 05). Conclusions Higher BP level and variability may increase the risk of HT in patients with massive cerebral infarction after cardioembolic middle cerebral artery occlusion. A smooth and slow antihypertensive treatment may need for these patients.

In either type 1 or type 2 diabetes,there is significant loss of β cell mass.Understanding the changing of β cell mass in the course of diabetes would provide important information for diagnosis and treatment.Functional imaging like magnetic resonance imaging or positron emission tomography (PET) can provide safe and noninvasive detection of loss of β cell mass in the course of diabetes.Among them,radio-labelled imaging is the most sensitive imaging procedure of the β cell ; For dihydrotetrabenazine PET imaging aiming β cell mass,there has been some primary outcome.For the key factor causing type 2 diabetes,18 F-6-deoxy-6-fluoro-D-glucose (18F-6-FDG) PET imaging is an effective tracer to study the glucose transporting condition in vivo.Further development of functional imaging will be of great value in diagnosis and treatment of diabetes.
