OBJECTIVE:To study the classification of deviation in drug production. METHODS:From the perspective of dom-inant and hidden deviation,combining with the theory of risk management,risk of deviation was evaluated with different risk man-agement tools to define the severity of the deviation,and it was handled by different methods. RESULTS & CONCLUSIONS:Ac-cording to the identifiability of deviation in actual management,the deviation was divided into dominance and hidden deviation. The dominant deviation can be divided into deep and shallow level. Whether the causes of deviation could be cleared and the conse-quences could be estimates were judged after the shallow level classification,and the deviation was further divided into simple and complex deviation. As for deviation complex,it could be evaluated with the tools of risk management to define the deviation severi-ty. As for hidden deviation,it needed beforehand preventing with the tools of risk management directly to define deviation levels and provide reference for preventive measures. In the process of deviation management,key point is to relay on the scientific meth-od to identify and classify deviation,and divide the influence levels. Combining the theory of risk management to select and use risk tools is the effective way to solve the problem.

Effect of p-nitrophenol shock on microbial populations and sludge activity in UASB reactor was studied by DGGE-PCR of 16S rDNA fragments and detection of COD removing and biogas yield.The results showed that p-nitrophenol seriously inhibited the sludge activity,resulting in the drop of biogas and COD removing rate.The 40mg/L p-nitrophenol had more inhibition than 20mg/L p-nitrophenol.It would take 27 and 16 days respectively for reactor to recover after 40mg/L and 20mg/L p-nitrophenol shock.The diversity of eubacteria and methanogens were also effected by the p-nitrophenol shock.The variation of eubacteria was more than that of methanogens after p-nitrophenol shock.The drop of biogas was mainly related to the variation of Methanosaeta sp.and Methanomicrobia sp.after p-nitrophenol shock.Among the eubacteria the population of Chloroflexi sp.、Bacteroide sp.and Anaerovibrio sp.decreased greatly after p-nitrophenol shock.And more,the Rheinheimera sp disappeared after 40mg/L p-NP treatment.But the Flavobacteria sp.appeared after p-nitrophenol shock,which was probably related to the degradation of p-NP.

A method to determine dihydroxyacetone (DHA) in fermentation broth was developed by high performance liquid chromatography (HPLC). DHA was separated on a Alltima C18(5?m,250?4.6mm). The mobile phase was 0.5% methanol solution (pH adjusted to 3.0 with H3PO4), the flow-rate was 1.0 ml/min and the detective wavelength was 200 nm. The detection limits of DHA was 0.1 g/L~10.0 g/L. 6.2 g/L DHA in the fermentation broth was detected by HPLC, which was in agreement with the result by spectrophotometric method.The method was applicable for DHA determination in the fermentation process.

More than 20 strains capable of producing dihydroxyacetone from glycerol were isolated from 4 different natural environment samples by using two detection methods. The strain 6-8 which could grow on medium containing glycerol as sole carbon source had a higher converting capability. Under a better culture, the highest DHA production of the strain 6?8 reached 6.4 g/L. In addition to general morphological and bio-chemical characteristics, the strain 6?8 was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain 6-8 had similarity of 99.7% with Acinetobacter sp. suggesting that the strain 6-8 is one of subspecies of Acinetobacter sp.

OBJECTIVETo investigate the optimal extraction process of polysaccharides from S. fusiforme by enzymatic treatment.
METHODThe optimum extraction conditions were obtained by the experiment with the orthogonal design. The content of polysaccharides of S. fusiforme was determined by spectraphotometry.
RESULTThe amount of enzyme and temperature significantly affected total polysaccharides of S. fusiforme.
CONCLUSIONThe optimum extraction conditions include the addition of 1. 2 x 10 (4) U x 100 g(-1) enzyme into water at pH 4. 5, and the subsequent treatment for 10 min while the temperature is maintained at 45 degrees C.

OBJECTIVE:
To explore the molecular mechanism of proliferation inhibition of human breast cancer cell MCF-7 regulated by E1A gene.
METHODS:
E1A gene was transfected into MCF-7 cells by liposome reagents. RT-PCR and Western blot were used to detect E1A mRNA and protein expression and HER-2 mRNA in MCF-7. The proliferation and colony formation of MCF-7 were measured by 3-(4,5-dinmethylthiahiazo-z-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and soft agar formation assay. The apoptosis of MCF-7 cells regulated by E1A expression was examined by flow cytometry.
RESULTS:
E1A was not endogenously expressed in MCF-7. E1A expression in MCF-7 could significantly decrease HER-2 mRNA and protein expression. Flow cytometry indicated that the apoptosis of MCF-7 could be induced by E1A. Meanwhile, E1A gene could significantly inhibit MCF-7 proliferation and colony formation in soft agar.
CONCLUSION
E1A gene can decrease HER-2 expression and induce the apoptosis of human breast cancer cell MCF-7, and inhibit the proliferation and colony formation of MCF-7.

Objective To observe whether the expression of interferon-regulatory factor genes are re- lated to systemic lupus erythematosus (SLE).Methods The clinical data of 45 SLE patients and 37 normal controls were collected.Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression (indicated as-??Ct value) of IRFI,IRF4,IRF8 in patients with SLE and those in the controls.Results The levels of IRF1,IRF4 and IRF8 mRNA were-3.90?0.19,-8.04?0.25 and 3.60?0.15 respectively in normal controls.In SLE patients, IRF4 mRNA expression was -8.82?0.18,higher than that in normal (P=0.011).But IRF8 mRNA expression was 3.09?0.13,lower than that in normal (P=0.012).Conclusion Abnormal IRF mRNA expression is found in the peripheral blood of SLE patients.IRFs may play roles in the pathogenesis of SLE by affecting the differen- tiation of Th cells.

Objective To observe the effect of full-responsibility nursing model in rehabilitation exercise on patients with chronic heart failure (HF).Methods Eighty-six patients with HF were randomly divided into observation group and control group,with 43 cases in each group.sixteen nurses were randomly divided into A and B group ; A group carried out full - responsibility nursing model and was in charge of the rehabilitation exercise of observation group,B group carried out routine holistic nursing model and was in charge of the rehabilitation exercise of control group.After 4 weeks,the effects including EF,6MWT,the knowing of rehabilitation exercise,satisfaction to the hospital were evaluated.Results Before rehabilitation exercise,there were no significant differences in EF and 6MWT( P > 0.05 ).After 4 weeks,EF was( 54.13 ± 9.12 ) and 6MWT was (402.63 ± 74.81 ) in the observation group,while EF was (43.26 ± 8.57 ) and 6MWT was ( 336.16 ±75.82) in the control group.There were significant differences between the two groups ( t =2.093,2.145 ; P <0.05).there were significant differences before and after rehabilitation exercise in two groups ( P < D.05 ).After 4 weeks,EF and 6MWT of the two groups were both increased,but the effect of the observation group was better (P < 0.05 ). After 4 weeks,there were significant differences in the knowing of rehabilitation exercise and the satisfaction to the hospital in the two groups ( P < 0.05 ).Conclusions Full-responsibility nursing model in rehabilitation exercise can make an effective effect.
