Following the increasing of amount and improving of management year by year,the management of scientific research funds must be informationized.We established an information management system of scientific research funds,according to the management standards of different departments which were the sources of funds.The system including two main modules.:budget management and expenditure management.The main functions of the system as follows:establishing the budget,expensing according to the budget,inquiring the feedback data,etc.The system increased the accuracy and effectiveness of management of scientific research funds.

The DNA fragment RM07 was isolated from halophilic archaea Halobacterium halobium, which can function as promoter not only in halophilic archaea, but also in Escherichia coli as eubacterial promoter. Sequencing analysis indicated that it possessed the typical consensus sequences (-35 and -10) of bacterial gene promoter, which was confirmed by further deletion analysis: With its -35 sequence deleted and -10 sequence left,DNA fragment RM07a nearly cannot initiate transcription;With its both -35 and -10 sequences,RM07b DNA fragment could be active as promoter at a level even higher than RM07. Our research also showed that the promoter function of RM07 fragment in Escherichia coli was under the control of environmental factors,especially its positive correlation with the increasing concentration of sodium chloride. Therefore, RM07 DNA fragment may be potential1 novel promoter source for constructing double-function vectors. It also has special significance in elucidating the issues of the fusing characteristics of archaea and lateral gene transfer between archaea and bacteria.

OBJECTIVE To report the investigation on validating clinical moist sterilizer by applying wireless thermo-loggers in accordance with the advanced Euro and British standards.METHODS The validation had been implemented with microbiological tests and thermometric tests to measure the temperature distribution of the chamber of sterilizer,the temperature and time relation inside the tested package of small and challenge loads,the pressure of the chamber and the temperature beside the drainage.RESULTS The measurements presented the relation between temperature and time measurements of the spots inside the chamber of the tested sterilization loads.CONCLUSIONS The measurement results indicate directly the operation condition and the temperature-time relation inside sterilization loads.These measurements are helpful for controlling sterilization quality.The results of microbiological tests are negative,which are consistent with that of thermomeric tests.

Objective To study the effect of transfection of livin antisense oligodeoxynucleotide (Livin ASODN) on Livin mRNA and Livin protein expression and proliferation of QBC939 cells.Methods Livin ASODN was transfected into cell line QBC939 by LipofectamineTM 2000. Fluorescence microscopy was used to observe the ASODN transfected cells and to calculate the rate of transfection.to measure Livin mRNA and Livin protein expression by RT-PCR and immunohistochemistry and con-focal laser scanning microscopy after the transfection. Changes in cell proliferation were detected by MTT. Results The highest efficiency was at 24 hours after 500 nmol/L Livin ASODN transfection.The results of MTT showed that the inhibition of cell proliferation of QBC939 cells was most obvious at 60 hours after Livin ASODN transfection (P<0. 05). The level of Livin mRNA and Livin protein expression in the ASODN group was obviously lower than that in the control group (P<0. 05).Conclusion The transfection of Livin ASODN inhibited Livin gene and Livin protein expression, and obviously inhibited the proliferation and depressed the vitality of QBC939 cells.

Purpose To explore the specific diagnostic markers of Sertoli cells and germ cells for testicular biopsy. Methods Normal testis from 3 patients who suffered from carcinoma of the prostate and treated with testis castration, and 15 testicular biopsy tissues were stained by EnVision two steps with WT-1, AR and Ki-67. Results The expression of WT-1 and AR protein were found in Sertoli cells from the 3 normal testis and 15 testis biopsy, the positive rate were all 100%, and non was positive in germ cells. The germ cell was positive for Ki-67, and the positive rate was 100%. Conclusions WT-1, AR and Ki-67 may be the specific diagnostic markers of Sertoli cells and germ cells for testicular biopsy, which may contribute to the diagnosis of testicular biopsy.

To developing a simple, rapid and sensitive immunoaffinity method for extracting DNA before amplification by the polymerase chain reaction(PCR). Using monoclonal anti-DNA bound to colloidal-gold beads(which called immunocolloidal-gold ) and extracting DNA from the specimen before amplification by PCR. The immunoaffinity method we use is extremely efficient in extracting DNA at low concentration, also, the beads carrying the DNA/anti-DNA complexes can be added directly to a PCR mixture without elution, and the presence of PCR inhibitors in specimens has no effect on amplification. When applied to serial dilution bacteria suspension, the detection of limit can be 100 CFU/mL, and the sensitivity of detecting artificial soil sample and milk sample were 101 and 100 CFU/mL. The immunoaffinity method described here can sever as a sensitive and practicable method for extracting DNA , particularly where samples have low concentrations of DNA or where the material is in poor condition.

As one of the most serious types of psoriasis, pathogenesis of erythrodermic psoriasis (EP) is unclear so far. In this study, we aimed to detect the levels of Th1/Th2 cytokine-associated transcription factors and T-lymphocyte clone in peripheral blood mononuclear cells (PBMCs) derived from EP patients, and gene expression level of T-bet/GATA-3 in skin lesion. The potential role of Th1/Th2 reaction pattern played in the pathogenesis of EP was also discussed. Serum levels of IFN-γ, IL-2, IL-4 and IL-10 were quantified by ELISA among 16 EP patients, 20 psoriasis vulgaris (PV) patients and 15 healthy controls. The expression levels of T-bet/GATA-3 in the skin lesion and PBMCs were examined by real-time qPCR. The ratio of Th1/Th2 was measured by flow cytometry. The levels of IFN-γ, IL-2, IL-4 and IL-10 were higher in EP patients than in the healthy controls. The levels of IL-4 and IL-10 were 69.44±11.45 and 12.62±4.57 pg/mL, respectively, in EP patients, significantly higher than those in PV patients and healthy controls (P<0.05). Flow cytometry revealed the levels of both Th1 and Th2 in PBMCs from EP patients were higher than those in healthy controls, and the Th1/Th2 ratio was dramatically lower than in PV patients (P<0.01). The ratios of IFN-γ/IL-4 and T-bet/GATA-3 in EP patients were both less than 1.0, suggesting a reversal when compared with the other two groups. Our study indicated that the EP patients exerted a Th1/Th2 bidirectional response pattern, and the balance of Th cell subsets inclines to Th2, which might be one of the important mechanisms of EP pathogenesis.

The importance and feasibility was analyzed of the teaching BBS for aiding classroom teaching based on campus network.

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.
