Objective:To explore the perioperative treatment principle for arteriovenous fistulas of hemodialysis,the related factors to the success of operations and the intervention measures.Methods:1820 cases in the 2 periods from 1992to 2000 and from 2001 to 2008 were selected,and the relation of the change of primary diseases,the difference of their blood vessel condition before operation,different operation methods and different treatment after operation to the successful rate of operation and fistulas blood flow was analyzed and statistical analysis was made to the related data.Results:The ratio of secondary renal disease in the second period was much bigger and of significant difference with that in the first period(P

OBJECTIVE To survey the status quo of hospital infection management and countermeasures in township health center. METHODS To adopt a unified examination and assessment survey,the township hospital infection management,including organization,personnel training,monitoring,disinfection and isolation,occupational protection,sterile disposable medical supplies and medical waste management was investigated in 15 Lanxi Town ship Health Centers. RESULTS Only 2 centers had management organizations (13.33%),5 (33.33%) to participate in personnel/training,no one carry out the monitoring of hospital infection,with fuzzy concept about cleaning disinfection and sterilization and poor awareness of occupational protection. CONCLUSIONS Realizing a sound organization improving hospital infection management staff and intensive training,increaseing the investment and strengthening th supervision and inspection are in accordance with the law and guide management of patients in rural areas to be assured of a secure medical establishment.

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of non-Hodgkin's lymphoma.An uncommon subset with myc and either bcl-2 or bcl-6 rearrangement,also known as ‘double-hit’ lymphomas,is considered very aggressive clinical course and poor prognosis despite high-intensity chemotherapy.Recently,these lymphomas have received increased attention.This review explores the existing literatures for the involved genes with their functions,clinical features,diagnosis and treatment.

Objective:In order to improve operator’s cognitive level for standardized disinfection, this paper will focus on analyzing and interpreting the disinfection procedures for some common dialysis machines.Methods: This paper will interpret and compare the disinfection procedures for three brands of dialysis machines in the following aspects: the choice of the disinfectant, the disinfection method, the concentration of the disinfectant and the injected volume of the disinfectant, etc.Results: The procedures of hot disinfection with citric acid were used completely in those three brands of dialysis machine, and the procedure of sodium hypochlorite need been used periodically to remove the proteins and other organic matter.Conclusion:Although the dialysis machines provide almost complete and efficient disinfection procedures, but the operator should need to select the most suitable procedures according to their practical situation. If the operators cannot master the disinfection procedures and have not noticed the importance of it, the wrong operator will lead to incomplete disinfection, affect the normal operation of the dialysis machines and increase the risk of cross-infection.

Objective This prospective study was performed to evaluate the role of oral glucose toler-ance test(OGTF) in evaluating the preoperative status and postoperative complications of patients with hepa-tocellular carcinoma. Methods One hundred and twenty-eight patients with primary hepatic carcinoma (PHC) were divided into 3 groups according to the resection, in which the resection of no more than 1 seg-ment called group A, the resection of 1-2 segments called group B, the resection of more than 2 segments called group C. OGTT, routine liver function tests and Child-Pugh classification were performed in these pa-tients preoperatively. The postoperative complications were also recorded. Results Blood glucose lever of 60 min and 120 min after glucose loading test in Child B (11.23 mmol/L ± 2. 78 mmol/L, 11.79 mmol/L± 3.48 mmol/L) were significantly higher than that in Child A (8.56 mmol/L±2. 36 mmol/L, 6. 78 mmol/L ±1.60 mmol/L,P <0.01) ,but the blood glucose lever of 0 min and 30 min showed no difference. The rate of diagonis of DM in Child B was 28. 30% ,which was higher than Child A(13.33% ,P =0. 035). The OG-TT results for the L-shaped curve showed that postoperative complications were significantly higher than that of type I and P in group A and B. I-shaped and L-shaped were found ascites in group C. The cases with jaun-dice all showed L-shaped curve. When the patients' OGTT curve was P -shaped, the ascites production rate was no significantly different in these three groups. With the increase of the removal in liver, ascites produc-tion rate increased evidently in I-type and L-type(P < 0. 05). Conclusions OGTT is worthwhile to assess hepatic function reserve and postoperative complications for patients with PHC. Combination of OGTT and Child-Pugh classification has higher predictive value on hepatic function reserve.

Attenuated Salmonella can be used not only as live vaccines but also as vectors for exogenous genes. As vectors, attenuated bacteria can deliver genes directly to tumor tissues, leading to the expression of the cloned genes and induction of specific anti-tumor immunologic responses to inhibit tumor growth. Using attenuated Salmonella as a vector offers a new approach for vaccine development.

Objective Comparing the variability of four genes of HCMV in the population and the therapy process of single patient.Methods Using PCR to amplify the four genes and restriction enzyme to validate four fragments, These four genes are UL55,UL57,UL86 and UL122 whose coding products are glycoprotein B,single chain binding protein,main capsid protein and IE pp86 separately. Then we use AD169 to optimize the conditions of PCR and restriction enzyme. then we use these conditions to detect 200 blood specimens. Results The PCR positive rate of UL55 is 12.5% and restriction positive rate is 10.0%, which has marked difference with other 3 gene segments(P

The low sensibility of MR molecular imaging to signals makes signal amplification exceptionally important.This paper reviews the strategy of the reporter gene signal amplification in MR molecular imaging.

DNA methylation is an important epigenetic system. It plays many crucial roles in the gene regulation. With the development of the high-throughput detection techniques, the bioinformatics study has been an active hot topic in the research of DNA methylation. The major achievements and progress on the prediction of DNA methylation status, the mechanism that the majority of CpG islands are resistant to DNA methylation, the relationship between DNA methylation and other epigenetics, as well as the association between aberrant DNA methylation and the tumorigenesis were reviewed in this article.

Objective To study the calculating model of military medical equipment readiness rate and the main affecting factors in order to make a valuable reference to the decision -making of medical organization for the further medical support. Methods Based on analysis of the problems in calculating method of military medical equipment readiness rate at present, a new improved calculating model and the analysis method relating to assigning mission was put forward by combining the technical requirements of GJB5338-2005 and the actual of medical equipment management. The factors affecting readiness rate in process of manufacturing, operation and maintenance support were analyzed. Results A new improved calculating model of military medical equipment readiness rate was established and the evaluating method was made by adjusting those correlated parameters in the calculation formulas. Conclusion The solution of the model is simple and convenient and the analyzing results show that the readiness rate is close to the reality. It is a practical method for achieving quality state information of medical equipment, so it can meet the requirements of military medical equipment organization in peacetime.
