Objective: To analyze the present situation of the management of large-scale instruments in a medical school and give some reasonable suggestions. Methods: Through the research on the use of 85 large-scale instruments in our university, we tried to find out the methods of improving the utilization ratio of large-scale instruments. Results:There are many reasons of the poor management and low utilization rate of large-scale instruments in medical schools. Conclusion: Taking some measures could effectively improve the utilization rate of large-scale instruments in medical schools, such as simplifying the working procedure, solving the operating and repair expenses, strictly controlling argumentation, drawing up scientific evaluation and incentive measures and so on.

Automated body fluid cytology analysis has been accepted by clinical laboratories gradually.The improvement of efficacy and analytical precision can overcome some defects of traditional manual method,such as time-consuming and poor repeatability.To make use of the advantages of automated fluid cell analysis technology,the automated method and microscopic method must be combined by setting review rules.Meanwhile,more attentions must be paied to sample collection and specimen preservation at pre-analytical stage,verification of instrument performance at analytical stage and necessary clinical communication at post-analytical stage.Only if a complete system of quality management,standardization of procedures,result validation and interpretation is implemented in the routine work,the clinical significance of body fluid cytological analysis can be recognized in clinical practice.

The experiences and features of XU Shu-wei's clinical application of moxibustion is studied in this article with method of review research. XU Shu-wei attached great importance on yangqi and the functions of spleen and kidney. At the same time, warming-reinforcing method was recommended in treatment as well. Not only treatment with medicine was emphasized, but also moxibustion was encouraged to be applied in clinic. A warming-reinforcing method with moxibustion was recommended for diseases such as yinzheng (yin syndrome), yin-du (extreme yin syndrome), yang deficiency syndrome, stroke, prolapse of anus and furuncles on back. Flexible moxibustion methods were applied based on differentiation of syndromes. Various acupoints and moxibustion manipulations were selected according to different conditions. With the proved therapeutic effect, XU Shu-wei was held as the forerunner of warming-reinforcing method in the acupuncture history of China. Meanwhile, he also made certain contribution on the establishment of the Wenbu Xuepai (the warming-reinforcing school) in the Ming Dynasty (1368-1644).

Objective To screening up-regulated protein kinases and their inhibitors in order to provide new targets for molecular thera-py of nasopharyngeal cancer.Methods GEO database and SAM software were employed to screen the up-regulated protein kinase gene in nasopharyngeal cancer.Based on DAVID database,the regulating functions of kinases were identified.The inhibitors of up-regulated kinase genes were identified by Selleckchem database.Literature mining was used to screen the potential anti-cancer drugs.Results Totally 2360 differentially expressed genes including 21 up-regulated protein kinases (CHEK1,CHEK2,PRKDC,AURKA,VRK2,STK17A,MELK,NU-AK1,TRPM7,MASTL,AXL,BUB1,BUB1B,CDK4,TTK,CDC7,CASK,AKT3,TBK1 and PBK)were identified in the whole genome profi-ling (Fold Change≥2,P <0.05).The results of function analysis showed the up-regulated genes were enriched in 10 function terms such as‘protein amino acid phosphorylation’‘phosphorylation’‘phosphate metabolic process’‘mitotic cell cycle’‘cell cycle phase’‘regulation of cell cycle’,and so on.The Selleckchem database analysis showed there were 9 up-regulated protein kinases equipped with 51 inhibitors which were proved already.The results of literature mining showed that 18 inhibitors of them had a few studies (less than 10 literatures)in cancer terms,and there was a potential to become new drugs to treat nasopharyngeal cancer.Conclusion A total of 21 up-regulated protein kinases were identified,and they might promote the nasopharyngeal carcinoma by regulating functions such as the cell-cycle control pathway.Their ki-nase inhibitors may have a potential role in anti-cancer treatment,which provided a new target point for molecular therapy of nasopharyngeal cancer.

Objective To study the role of bile reflux in the pathogenesis of stress ulcer after acute brain trauma in rat. Methods The animal model was reproduced by Allen's method with modification. The bile acid concentration in the stomach and blood, the pH value of the gastsic content, and ulcer index (UI) were assayed 1, 3, 6, 24 hour after the stress, and they were compared with that of sham injury group. Results In stress group, compared with sham injury group, the amount of bile acid in the stomach was notably increased( P

The template-independent teminal transferase activity of Taq DNA polymerase results in an overhanging dA at the 3′end of its PCR products. The pGEMX vector constructed in this experiment forms a single overhanging dT at its 3′end as the result of cleavage with Xcm I restriction enzyme. This vector is very efficient for direct cloning of PCR product obtained by using Taq DNA polymerase.Recombinant colonies can be selected by Blue/white screening. Moreover,insertion fragment can be easily released from the vector simply with either BamH I or Hind III digestion.

Objective Through investigating the situation of health care resources in Shanghai ,from the point of population and geographical area distribution, the article analyze the fair allocation of medical resources in Shanghai to provide the basis of decision-making in rational allocation of medical resources. Methods Use Lorenz curve and the Gini coefficient indicators, as well as Chain Proportion Method. Results The allocation of medical resources in population of Shanghai is fairly,and the trend of fairness will be enhanced. In the geographical allocation in space is more unfairness in Shanghai,and the fairness will be reduced. Conclusion The allocation of medical resources Municipal Population has few gap between urban and rural areas in the Shanghai which reached a fair comparison, but in the geographic distribution of has a larger gap between urban and rural areas. Most of the medical resources concentrated in large hospitals in the urban centers. The distribution of Medical resources should be rational and the health service system should be improved to improve medical and health service accessibility.

Objective No reports has been found to date on whether frequency compounding can improve elastographic image signal to noise ratio (SNRe) and how it affects elastogram performance.In this paper simulations investigation was carried out on transmit-side frequency compounding (TSFC)for elastography.Methods 50 mm×50 mm tissue model was simulated with two round hard inclusions of 10mm diameter uniformly distributed along the tissue central axial line,and their elasticity modulus were 10 times of the background.Then simulation of 3.5 MHz、5 MHz and 7.5 MHz probes were introduced to form compression elastography of the double-lesion model by quasi-static compression method (applied strain 1%).Then,sub-elastograms obtained by the combination of 3.5 MHz and 5 MHz,3.5 MHz and 5 MHz,3.5 MHz and 7.5 MHz were compounded,respectively.Results Before compounding,signal to noise ratio (SNRe) of the various sub-elastograms were 8.42,9.62,10.73,respectively,contrast to noise ratio (CNRe) were 11.35,14.82,18.37,respectively and axial resolutions were 9.83,9.82,9.81.After compounding elastograms,the SNRe were 11.82,13.05,19.45,CNRe were 22.31,27.63,56.12,while axial resolutions were 9.83,9.83,9.83.Conclusion Frequency compounding elastograms have higher SNRe and CNRe than any sub-elastogram before compounding and have no axial resolution loss.The TSFC can improve elastogram performance efficiently and frequency compounding for elastography enhancement is feasible.

Objective: This study was to observe the changes of IL-6 gene expression in acute repetitive hypoxia. Method: When the ratio of living cells was more than 95%, nerve cells cultured were passed through with mixed gases of 95% N_2+5%CO_2 for 3 min followed by another gases mixture of 95% O2+5% CO_2 for 10 min. After repeated the experiment as above, the alteration in the expression of IL-6 gene was measured using the RT-PCR method. The prod ucts of PCR were analyzed with computer Gel imaging and image analysis instrument. Result: After the first hypoxia IL-6 gene expression enhanced, and after the second hypoxia, it was still stronger than baseline although it declined slightly. There was no significant RNA disintegration. Conclusion:The IL-6 involves in the cellular defense in hypoxia adaptation.
