OBJECTIVE:To provide reference for the development of pharmaceutical care for periconceptional women. METH-ODS:Probability proportionate to size sampling(PPS)method was adopted to select participants from periconceptional women in Yongchuan District. The participants were investigated by questionnaires about drug use safety knowledge,attitude and behavior. Ep-idata 3.0 software was used to establish database. The data were analyzed with SPSS 15.0 software. RESULTS:Totally 800 ques-tionnaires were distributed and then 779 valid questionnaires were collected with effective rate of 97.38%. The total awareness rate of knowledge about drug use safety was 57.69%. The awareness rate rise with the increase of educational level (P<0.01). The awareness rate was higher in pregnant women than in prepregnant ones,with statistical significance in most of the questions(P<0.05 or P<0.01). For questions about attitude for drug use safety,the positive answer rate was higher in pregnant women than in prepregnant ones,with statistical significance in most of the questions (P<0.01). Among 385 pregnant women,only 56.88% re-ceived folic acid following the WHO recommendation. Of 181 pregnant women who had taken medicine,8.29% indicated that the physicians or pharmacists did not inform that whether the medicine affected pregnancy. CONCLUSIONS:Among periconceptional women,awareness rate of drug use safety is in low level and varied by their educational levels. There are difference in awareness rate of drug use safety and attitude between prepregnant women and pregnant woman. Drug use behavior of pregnant woman is to be modified.

Objective To investigate the impact of alterations within the space of Disse micro- environment on the migration of hepatic stellate cells(HSC) during the process of liver fibrosis,and to ex plore the novel mechanism of liver fibrosis from the view of cell migration.Methods A modified in vitro Boyden chamber system to partially mimic in vivo microenvironment of Disse space of normal and liver fibrosis was employed.The effects of fibrogenetic growth factors on the migration of HSC in liver fibrosis were observed via cell migration and cell proliferation experiments.Results Enhanced platelet-derived growth factor(PDGF)-BB,transforming growth factor(TGF)-?1 and/or epithelial growth factor(EGF) in liver fibrosis resulted in an increase in migratory capacity of activated HSC.The enhanced migration of HSCs induced by PDGF-BB was partially associated with their increased proliferation,while,TGF-?1 or EGF-induced migration was proliferation independent.The elevation of basic fibroblast growth factor (bFGF) or vascular endothelial growth factor(VEGF)during liver fibrosis had no effect on the migration of HSCs.Conclusions The study provides valuable insights into the role of space of Disse microenvironment in regulating HSC migratory behavior.TGF-?1,PDGF-BB and EGF,which increased in liver fibrosis, could induce the migration of activated HSC.However,bFGF or VEGF has no such kind of effect,al- though they also increased during liver fibrosis.

Objective To investigate the anticancer effect of oxymatrine on cervical cancer cell line (HeLa). Methods MTT assay was used to detect the anti-proliferative effect of oxymatrine.Transwell chamber was used to detect the anti-metastatic effect of oxymatrine.Real-time PCR was used to detect the mRNA levels of MMP-2 and MMP-9.Western blot was used to detect the protein levels of MMP-2,MMP-9,AKT,p-AKT and GADPH. Results We found that application of oxymatrine significantly inhibited the growth of HeLa cells at the concentration above 0.8 mg/mL.We also found that oxymatrine (0.1,0.2 and 0.4 mg/mL)inhibited the invasion of HeLa cells under cytotoxic dose,which was (77.07±20.43)%,(53.95±18.17)% and (20.35±11.20)% of cells that migrated through the matrigel when compared with those of non-oxymatrine treatment group (P<0 .0 5 ). Further research found that oxymatrine (0.1,0.2 and 0.4 mg/mL)could reduce the expression of MMP-2 at the mRNA level,i.e.(82.76±8.71)%,(39.51±12.79)% and (21.53±5.38)% of the expression level when compared with that of non-oxymatrine treatment group (P<0 .0 5 ).The protein expression level of MMP-2 in 0 .4 mg/mL group was (64.69 ±16.52)% of non-oxymatrine treatment group (P<0.05).The phosphorylation level of AKT in 0.4 mg/mL group was (41.27±7.13)% of non-oxymatrine treatment group (P<0.05).Conclusion Oxymatrine can inhibit the invasion of HeLa cells by reducing the expression of MMP-2 via inhibiting the activity of AKT signal pathway.All together,our findings bring new insights into the mechanism of the anticancer effects induced by oxymatrine treatment.

Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.

Objective To explore the characteristics and surgical managements of recurrent retinal detachment in silicone oil tamponade eyes.Methods The records of consecutive series of 134 patients (134 eyes) with recurrent retinal detachment in silicone oil tamponade eyes from January 2012 to December 2015 in our hospital were reviewed retrospectively,the vitrectomy combined with silicone oil replacement or scleral buckling procedure were performed.The follow-up time was 6 months,the surgical efficient was evaluated.Results 101 eyes underwent vitrectomy combined with silicone oil replacement.Retina was completely reattached in 79 eyes,and vitrectomy was reperformed in the left 22 eyes,the successful rate was 78.2％ (79/101);The visual acuity improved in 16 eyes,unchanged in 56 eyes,decreased in 29 eyes;The intraocular pressure of 31 eyes increased more than 25 mmHg (1 kPa =7.5 mmHg).33 eyes underwent scleral buckling procedure.Retina was completely reattached in 23 eyes,and vitrectomy combined with silicone oil replacement was performed in the left l0 eyes,the successful rate was 69.7％ (23/33);The visual acuity improved in 5 eyes,unchanged in 16 eyes,decreased in 12 eyes;The intraocular pressure of 14 eyes increased more than 25 mmHg.Conelusion For limited retinal detachment caused by inferior or peripheral holes,proliferative vitreoretinopathy in the A or B-class,the refractive medium does not affect the fundus examination,scleral buckling surgery is preferred;For the hole in the posterior pole or extensive retinal detachment caused by giant retinal holes,proliferation or retinal fixed fold formation,vitrectomy combined with silicone oil replacement is a better option.
