Objective To investigate the expression of transforming growth factor-?(TGF-?) in the villus and deciduas of different outcomes after administration with mifepristone and misoprostol in the termination of early pregnancy. Methods From May 2004 to March 2005,50 women who were comfirmed early pregnancy and requested termination of pregnancy in the outpatient department were recruited.Patients with medical abortion were divided into two groups according to the final outcomes: group of complete abortion(n=15) and group of incomplete abortion((n=)15).Another 20 patients with surgical abortion were served as control.The villus and deciduas were collected at the third day of medical abortion,whereas the same was done at the day of surgical abortion.The expression of TGF-? in villus and deciduas of the three groups were measured by immunohistochemical method. Results The age,gestational age,diameter of gestational sac and levels of serum E_(2),P and ?-HCG before abortion were similar in these groups.Compared with the other two groups,the expressions of TGF-? in the villus and deciduas in the group of complete abortion were significantly decreased(P

AIM: To analyze the application on frequency domain optical coherence tomography ( OCT ) technology of pathologic myopia optic disc neurosensory retinal thickness changes and its relationship with axis oculi, sex and age, and help for the early diagnosis of pathological myopia and primary open angle glaucoma.
METHODS:Collected 96 eyes of normal eyes ( axis oculi 23-24mm) and 153 eyes of pathologic myopia eyes ( axis oculi 25-27mm 80 eyes, >27mm 73 eyes). We measured the thickness of nerve fiber layer of the optic disc by OCT and analyzed their relationship with axis oculi, sex and age with multiple linear regression analysis.
RESULTS: The observation group showed significant smaller average thickness of peripapillary, superior, inferior, nasal than the control group ( P<0. 05 ); the difference in the temporal quadrant between the groups were no statistically significant differences (P>0. 05); The partial correlation coefficient of peripapillary average thickness of nerve fiber layer and axis oculi was -1. 31, gender was 5. 21, age was -0. 12.
CONCLUSION:The thickness of nerve fiber layer of the optic disc in the pathologic myopia eyes are decreased than normal eyes, axis oculi, sex and age are influenced factors. The pathologic myopia patients should use different index combined with optic nerve fiber layer thickness decreased to help for the diagnosis of early primary open angle glaucoma.

Objective To study the time distribution of non-agriculture employed population spent in a working day in China, and to provide basic information for intervention strategies.Methods The data of 2002 China Nutrition and Health Survey were used. The information on daily activities including occupation,transportation,exercise,housework,sedentary activity and sleep was described.Results Non-agriculture employed population spent 8.41 h,0.58 h,0.09 h,3.11 h,1.40 h and 7.89 h on occupation, transportation,exercise,sedentary activity,housework and sleep,respectively.Administrator,technologist and clerks spent less time on occupation activity than service workers,production and transportation workers and others did,and they spent more time on sedentary activity.Male spent more time on occupation activity and less time on housework and sleep than female did.People in rural area spent more time on occupation activity than those in urban area,but less time On transportation and sedentary activity.Conclusion Differences in time use among different employed groups,gender and area were found,which should be considered when intervention measure is developed.

Objective To systematically review the effect of telephone intervention on colostomy patients.Methods The randomized controlled trials (RCTs) of telephone intervention on colostomy patients were searched in CBM,VIP,CNKI and Wanfang database and analyzed by RevMan5.2 software.Results Nine RCTs were included.Results of systematic evaluation showed that there were statistical difference in the self-care status,obeying doctors' order,satisfaction degree,self management ability,quality of life.Conclusions The effect of telephone intervention on colostomy patients was better than that of the traditional intervention.

The development of printing ink is a challenge for binder jetting 3D printed preparations, which directly determines the quality of the printed product. This study adopted a 2³ full-factor Design of Experiment (DoE) with three central points to optimize the printing ink composition of levetiracetam 3D printed dispersible tablet based on the concept of Quality by Design. Firstly, using polyvinyl pyrrolidone K30, glycerin and polysorbate 20 as independent variables based on 40% (v/v) isopropanol aqueous solution, and weight variation, hardness, friability and dispersion uniformity of the printed tablets were used as dependent variables. Then obtained the design space of the printing ink prescription by DoE model analysis, and the response optimizer was used to obtain the optimal printing ink prescription: isopropanol aqueous solution containing 0.1% (w/w) polyvinyl pyrrolidone K30 and 4.0% (w/w) glycerin. The jetting mechanism and wettability of the printing ink were analyzed, and different strengths of personalized 3D printed tablets were prepared and characterized, which verified the rationality of the printing ink formulation. This study provided a reference for the development of printing ink for binder jetting 3D printed preparations.
