Objective　To investigate the existence, intensit y and persisting time of biologic activity of bronchoalveolar lavage fluid (BALF ) collected from dogs with acute severe smoke inhalation injury in early post-i njury stage. Methods　BALF was collected 1 h after the est ablishment of acute severe sawdust smoke inhalation injury in 5 dogs, and the fl uid was perfused into the lungs of Wistar rats in the amount of 5 ml/kg (gro up C). Normal saline (group A) and BALF from normal dog (group B) were perfused into the lungs of rats and served as control. The respiratory rate, PaO2, lung water content and the expanding stability of lungs in all rats were determ ined at the time points of 4,12 and 24 h after the purfusion. Results　 Compared with the rats in group A and B, the rats in group C had higher mortality, wider range in RR, higher lung water content, PaO2 decreased obviou sly and lower lung expanding stability. The rats in control groups showed sl i ght mechanic obstruction in their airways in the course of experiment. Meanwhile ，the rats in group C showed higher oxidative activities and lower total anti-o xidative activities in lung tissues. Conclusion　It is certai n that the BALF collected from dogs with acute severe smoke inhalation injury in early post-injury stage could induce obvious injury in lung structure of norma l rats, showing certain mechanic obstruction in small airways. The injuring act ivity of the BALF can be alleviated ultimately 24 h after the perfusion of the B ALF.

Allotypes and complotypes of Bf, C4A and C4B in 42 families with myasthenia gravis (MG) were determined by means of high voltage agarose gel elect rophoresis of EDTA plasma and subsequent immunofixation, in an attempt to determine whether specific allotypes and/or complotypes were associated with this disease. From the family-data, 108 complotypes were obtained, which could be classified into 28 kinds of complotypes. We found that there are positive linkage disequilibra in S42, S31 and S40,and negative linkage disequilibra in S32 and S41. Compared of these results with those of normal controls, the frequency of S42 is significantly increased in MG(P 0.05).Furhter analysis showed that the MG associated S42 may result from that C4A4 is strongly associated with MG, while C4A4 is in linkage disequilibrium with Bf S and C4A2. Preliminary association mechanism between C4A4 and MG was analysed and discused.

The gene of preferentially expressed antigen of melanoma(PRAME) is a gene marker of leukemia,which can be used to monitor the minimal residual disease,and can make us to comprehend the curative effect,prognosis,the grade of risk and can predict relapse.In addition,PRAME as a human tumour antigen,can be recognized by autologous cytolytic T lymphocytes,is a ideal target of immunotherapy in leukemia,and investigate the methylation level of PRAME gene CpG island,which can help us comprehend the relation of the mechanism of PRAME and leukemia.

CD133 molecule is a new symbol of hematopoietic stem cells ( HSC). It may be a symbol of cancer stem cells in some cancer. Up to now, CD133 - 1 molecule has been paid close attention to in much literature . But research of their relationship between CD133-1 and CD 133-2 has little. The study will focus on two different CD133 molecule so that HSC and leukemic stem cells can be distinguished with using subgroup molecule. And this will provide theoretical and experimental foundation for targeted therapy of leukemia.

Objective: By analyzing the three variables relationship of GDP, total health expenditure and physical capital input, to provide basis for health economic policy and distribution system reform in China. Methods: Using the data from 1978 to 2011, the VAR model of the dynamic relationship is established. Results: The establishment of VAR model is stable by unit root test, there is Granger relation between the 3 variables, the result of the impulse response function is obtained that GDP will increase the input of health costs and physical capital, and physical capital and health expenditure have a reverse relation. Conclusion: Total health expenditure has greater effect on economic growth compared with physical capital, the government should allocate health costs, improve social benefits from the prospective of improving the quality of workers to promote economic growth.

Soft tissue sarcoma ( STS) , which is mostly found in extremities and retroperitoneum, is a malignant tumor of the connective tissue with the low incidence ( 1% of all malignant tumors) and various kinds of histopathological types. Intraoperative radio-therapy ( IORT) can improve the therapeutic effects of STS and to reserve the functions of the related organs, holding the apparent ad-vantage in local control rate of the tumor. IORT may cause toxicity, such as wound infections, limb ischemic necrosis and fibrosis. However, with the gradual development of IORT equipment, incidence rate of toxicity may be further reduced. This paper reviews the history, indications and advantages, clinical efficacy and adverse effect of IORT in STS.

Objective: To investigate the expression of Skp2,c-Myc and P27kip1 protein,their association with clinicopathological features and the correlation between one and another.Method:Skp2,c-Myc and P27kip1 protein were examined by using immunochistochemical staining method in 20 cases of normal colorectal mucosa,20 cases of colorectal adenomatous polyp and 60 cases of colorectal cancer,and analysed the relationship with clinicopathologic features and between Skp2 with c-Myc and P27kip1 protein.Results:The positive rates of Skp2,c-Myc and P27kip1 protein in colorectal cancer were 71.67%,66.67% and 21.67% respectively.Moreover,the expression levels of Skp2 and P27kip1 protein in colorectal cancer were significantly associated with the pathologic grade,invasion deep,clinical stage and lymph node metastasis,c-Myc associated with the invasion deep,clinical stage and lymph node metastasis,but were independent of age and sex.Besides,in colorectal cancer,the expression levels of Skp2 and P27kip1 protein were inversely correlated,and the expression levels of Skp2 and c-Myc protein were positively correlated.Conclusions:The expression of Skp2,c-Myc and P27kip1 protein are associated with occurrence and development in colorectal cancer through their alteration,which is very important for assessment of malignancy degree and prognosis in colorectal cancer,and detection cancer of their expression provides theoretical basis for targetting therapy of colorectal.

Objective:To construct the expression vector pSuper.Hsp90?/pSuper for further research of the Hsp90?.Methods: In accordance with the Hsp90? sequence in gene bank,three sequences respectively targeting Hsp90? were cloned into the RNA expression vector pSuper.Results:It was confirmed by enzyme digestion,and electrophoresis that the construction of the recombinant expression vector pSuper-Hsp90?1,pSuper-Hsp90?2 and pSuper-Hsp90?3 was successfu1.pSuper-Hsp90?1 and pSuper-Hsp90?2 were successfu1 by sequencing.The expression of Hsp90? mRNA in HEK293 cells with pSuper-Hsp90?1,pSuper-Hsp90?2 and pSuper-Hsp90?3 decreased,and pSuper-Hsp90?1 notably decreased.Conclusion:The recombinant plasmid against Hsp90? RNAi can be successfully constructed in vitro,and pSuper-Hsp90?1 is the possible optimal target.

Objective:To explore the possibility of fresh amniotic membrane transplantation for reconstruction of ocular surface with acute burn and evaluate the effect.Method:20 cases(24 eyes)due to acute burn of ocular surface were performed fresh amniotic membrane transplantation.All patients were followed up for 12 months to 26 months,the mean follow-up was(15?2)months.Visual acuity,epithelial healing,corneal transparency,corneal neovascularization and transplanted amniotic membrane were observed.Results:After fresh amniotic membrane transplantation,ocular surface was soon stable,immune rejection and secondary infection didn't occur.In 19 of 20 cases(23 eyes) the amniotic membrane autolyzed or disappeared with epithelized corneal surface at 14 to 28 days after operation.In one case(one eye) autolyzed corneal ulcer occurred at 12 days after operation.After another medication treatment was invalid,lamellar keratoplasty was performed.In other cases with AMT visual acuity keeps CF/5cm.Conclusion:Fresh amniotic membrane transplantation can lighten corneal inflammation in acute course of burn,can prevent ocular surface from ulcer and deliquescion,can fasten the stabilization and reduce corneal neovascularization,which provide a good basis for the following keratoplasty.With regard to severe eye burn,the effect of AMT is limited.
