The study is to design chitosan-coated pilocarpine nitrate submicro emulsion (CS-PN/SE) for the development of a novel mucoadhesive submicro emulsion, aiming to prolong the precorneal retention time and improve the ocular absorption. CS-PN/SE was fabricated in two steps: firstly, pilocarpine nitrate submicro emulsion (PN/SE) was prepared by high-speed shear with medium chain triglycerides (MCT) as oil phase and Tween 80 as the main emulsifier, and then incubated with chitosan (CS) acetic solution. The preparation process was optimized by central composite design-response surface methodology. Besides the particle size, zeta potential, entrapment efficiency and micromorphology were investigated, CS-PN/SE's precorneal residence properties and miotic effect were especially studied using New Zealand rabbits as the animal model. When CS-PN/SE was administered topically to rabbit eyes, the ocular clearance and the mean resident time (MRT) of pilocarpine nitrate were found to be dramatically improved (P < 0.05) compared with PN/SE and pilocarpine nitrate solution (PNs), since the K(CS-PN/SE) was declined to 0.006 4 +/- 0.000 3 min(-1) while MRT was prolonged up to 155.4 min. Pharmacodynamics results showed that the maximum miosis of CS-PN/SE was as high as 46.3%, while the miotic response lasted 480 min which is 255 min and 105 min longer than that of PNs and PN/SE, respectively. A larger area under the miotic percentage vs time curve (AUC) of CS-PN/SE was exhibited which is 1.6 folds and 1.2 folds as much as that of PNs and PN/SE, respectively (P < 0.05). Therefore, CS-PN/SE could enhance the duration of action and ocular bioavailability by improving the precorneal residence and ocular absorption significantly.

Objective To study the influence and mechanism of hepatocyte growth factor (HGF) on myotube phenotype by myotube transdifferentiation induced by transforming growth factor-β1 (TGF-β1). Methods C2C12 cells were cultured in differentiation medium to induce myotubes formation. The cells were randomly devided into 3 groups. The control group without growth factor interruption. The induction group was supplemented with TGF-β1 (5 ng/mL) while the inhibition group was supplenmented with both TGF-β1 (5 ng/mL) and HGF (30 ng/mL). After 12 hours, the expressions of connective tissue growth factor (CTGF) protein in myotubes were detected by Western blot, the levels of CTGF mRNA were measured by RT-PCR. Results Compared to the control group, the protein and mRNA levels of CTGF significantly increased in TGF-β1 treated group , whereas the protein and mRNA levels of CTGF were significantly lower in inhibition group than those in induction group (P < 0.05). Conclusion HGF can inhibit the effect of TGF-β1 on the expression of CTGF in myotubes , which provides the evidences on the study of skeletal muscle cell transdifferentiation.

Objective To estimate the application value of dual-source CT on preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.Methods 20 cases with DeBakey type I aortic dissec-tion prepared to performe three branches aortic arch covered stent graft implantation were reviewed,and their CT findings were ana-lyzed in order to evaluate the guiding value for operation.Results The location and size of entries were determined and the diameter of aortic arch and three branchesas well as the intervals of three branches were also measured by dual-source CT.Furthermore, blood-supply for main vessel and complications related with covered stent were further analyzed prior to operation.The surgical pro-tocols were designed according to preoperational CT findings.Among all cases,13 cases were fit for new type of three branches aor-tic arch covered stent graft implantation.While the rest cases (N=7)were adopted other operations due to non-fitted indications. Conclusion Dual-source CT is of significance for preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.

OBJECTIVE:To evaluate the effect of psychological intervention based on pharmaceutical care on the communi-ty patients with essential hypertension. METHODS:172 patients with essential hypertension in a community health service certer in Nanjing Gulou area in 2013 were divided into control group(n=87)and intervention group(n=85)by simple random meth-od. Control group received conventional antihypertensive drugs and management,intervention group additionally received pharma-ceutical care and psychological intervention,it lasted 6 months. Blood pressure controlling,drug compliance,mastery of drug knowledge and health status in 2 groups before and after treatment were compared. RESULTS:Before treatment,there were no significant differences in the systolic blood pressure(SBP)and diastolic blood pressure(DBP)between 2 groups(P>0.05);af-ter treatment, SBP and DBP in 2 groups were lower than before,SBP and DBP in intervention group were lower than control group,the decrease degree of SBP and DBP was bigger than control group,the differences were statistically significant (P<0.01). 1 month after the beginning of intervention,there was no significant difference in the proportion of drug compliance be-tween 2 groups (P>0.05);1 month after the end of the intervention,the proportion of drug compliance in intervention group was higher than 1 month after the beginning of intervention and control group,the differences were statistically significant(P<0.05). Before treatment,there was no significant difference in mastery of drug knowledge between 2 groups (P>0.05);after treatment,the proportion of patients showed good and excellent mastery of drug knowledge was higher than before and control group,the differences were statistically significant (P<0.05). Before treatment,there were no significant differences in scores of physical,mental,social health subscale and SRHMS between 2 groups(P>0.05);after treatment,scores of physical health subscale and SRHMS in control group,each subscale and to-tal scale scores in intervention group were higher than be-fore, and scores of mental, social health subscale and SRHMS in intervention group were higher than control group, the differences were statistically significant (P<0.05). CONCLUSIONS: The psychological intervention based on pharmaceutical care can effectively promote the con-trol of blood pressure,improve drug compliance,mastery of drug knowledge,health status and mental situation,which is worth of popularizing and applying in community health services.
