OBJECTIVE:To optimize the processing technology of nine steaming nine drying of Rehmannia glutinosa. METH-ODS:L9(34) orthogonal experimental design was adopted to investigate the effects of the amount of added wine,steaming time and drying way on processing technology using the content and property of 5-hydroxymethyl furfural,acteoside,reducing sugar wa-ter extract,and character score as indexes. Comprehensive balance method was used for result evaluation,and optimized technolo-gy was validated. RESULTS:The optimized processing condition was as follows as the amount of added yellow wine 40%,steam-ing for 9 times,lasting for 6 h each time,blast drying at 70 ℃. Average value of each factor in validation test was 4.030 mg/g, 0.117 mg/g,0.376 7 g/g,0.733 g/g and 9.0 points,respectively. Their RSDs were 1.78%,2.9%,1.54%,2.13% and 0.1%(n=3). CONCLUSIONS:Optimized technology is reasonable and controllable in product quality,and can provide reference for quality control study of nine steaming nine drying of R. glutinosa.

In view of the existing situation of our hospital's information security system,this paper gives a reasonable analysis,including the risk analysis on the computer room' surroundings,basic facilities,applied stage,business system and security management. In addition,this paper suggests the countermeasures in technology and management to remove the hidden danger in the hospital's information security system.

Objective To investigate the key technology of PACS and HIS' integration.Methods Based on the application results of PACS and HIS,some key technologies are mainly described including standardization,storage,image pre-retrieve and preassignment,medical image compression,workstation and display system in integration.Results A better understanding for the role of PACS was made and a good foundation for advanced application was provided.Conclusion Key technologies must be well dealt with in the integration of PACS and HIS.

The training experience on XML doctor work station Version 2.2.7 was introduced.The relationship and differences between 2.2.7 version and word version were analyzed.It is especially highlighted how each function is embodied in the training system.The importance of using 2.2.7 version doctor work station on ex-period training is elucidated.

Objective To understand the current situation and the main influencing factors of hospital staffs' scientific research work in a affiliated hospital of Xinjiang,so as to provide the basis for improving awareness and level of scientific research of hospital staffs.Methods Survey using stratified random sampling method,using self-questionnaire research capacity factors questionnaire, to investigate the status of project leaders' research capacity in a affiliated hospital of Xinjiang.Using frequencies and relative number described ability to research,using x2 to compare research level among the various metrics.Scientific research levels' multivariate analysis using Ordinal Logistic Regression Analysis.Results regarding of scientific research,low level of 14 people,accounting for 4.9％,the middle level of 158 people,accounting for 55％,a high level of 115 people,accounting for 40.1％.Univariate analysis showed that age,length of service,education level,job title,whether master instructor it is,the research team,the situation of foreign training and learning opportunities,foreign academic session (times),support from leadership and family,non-working time for research,the total research funding (ten thousands yuan),discipline level have impact on the level of scientific research work.Ordinal Logistic regression analysis showed that age,length of service,educational level,whether master instructor it is,the total research funding (ten thousands yuan),discipline level are the main factors on level of scientific research work.Conclusions The scientific research level needs to be further improved,the level of scientific research is affected by many factors.

The aim of this research is to investigate the influence of microencapsulation on the expression of the oxidative stress genes and exogenous regulation of HepG2 cells. We compared the expression of hemeoxygenase-1 (HO-1) and glutathione S-transferases-A1 (GST-A1) in HepG2 cells under different culture conditions through real-time PCR. The effects of exogenous antioxidants on cell viability and albumin levels were also evaluated through MTT assay and ELISA assay. The results showed that after culturing for 6 and 16 days, the expression levels of HO-1 in encapsulated cells were approximately 4.9 and 3.1 times higher than that of monolayer cells at the same culture period; As for the expression levels of GST-A1, they were elevated to 11.2 and 33 times of monolayer cells (P < 0.05). Accordingly, we found that NAC at 5-10 mmol/L significantly increased the viability by 40%-70% and the biosynthetic function by 20%-30% in microencapsulated HepG2 cells (P < 0.05). GSH increased the viability of the encapsulated cells by 20%-55% and the biosynthetic function by 15% (P < 0.05). In conclusion, oxidative stress exists in the microcapsules and affects genes expression. Exogenous antioxidants can prevent the inhibition effects of oxidative stress on cellular growth.
