Aim To investigate the effect of iontophoresis on skin permeation of defibrase. Methods Iontophoresis was carried out in side-by-side chambers, excised rat skin membrane (RSM) or human epidermis membrane (HEM). The effects of electrode polarity, permeation medium pH and ionic strength were evaluated. Results Permeation of defibrase caused by anodal iontophoresis was more effective [the apparent permeability coefficient was (1.2±0.4)×10-4 cm·h-1] than that of cathodal iontophoresis[(4.3±1.4)×10-5 cm·h-1]. The amount of permeated defibrase caused by anodal iontophoresis in pH 7.4 medium was (25±5)×10-14 mol·cm-2, which was higher than that of in pH 6.4 permeation medium [(15±4)×10-14 mol·cm-2]. Conclusion Iontophoresis could enhance skin permeation of defibrase. Electroosmotic flow effect played an important role.

Objective To investigate the effects of Ginsenoside Rg1 on the expression of nitric oxide synthase (NOS) in brain tissue after cerebral arterial thrombosis in adult rats. Methods Thirty rats were randomly divided into the sham-operative group, cerebral ischemia-reperfusion group, Ginsenoside Rg1-L group, Ginsenoside Rg1-M group, Ginsen-oside Rg1-H group and nimodipine group (n=5 for each group). The ischemia-reperfusion rat model was established by mid-dle cerebral artery occlusion. The neurological score after reperfusion was observed. The levels of nitric oxide (NO), neuronal NOS (nNOS) and inducible NOS (iNOS) were detected by nitrate reduction method and colorimetric method. The expressions of nNOS and iNOS after reperfusion were analyzed by immunohistochemistry and Western blot assay. Results (1) The neu-rological scores after cerebral ischemia were significantly lower in Rg1-L group, Rg1-M group and Rg1-H group than those of cerebral ischemia-reperfusion group(2.40±0.55,1.80±0.84, 1.60±0.89 vs 3.20±0.84,P<0.05). (2) Compared with those of model group, serum levels of NO and iNOS were reduced, and nNOS levels increased, in three groups of Rg1. (3) Compared with those of model group, the expression of nNOS was significantly increased,and iNOS expression was significantly re-duced, in three groups of Rg1. Conclusion The preventive effects of Ginsenosides Rg1 on cerebral ischemia-reperfusion injury may be associated with the activation of nNOS and the inhibition of iNOS.

Objective To explore the effects of knocking down ULF gene on the apoptosis of non-small-cell carcinoma H1299 cell after treatment with etoposide.Methods Three ULF small interfering RNA(siRNA)sequences and one negative control siRNA sequence were designed and synthesized, and then individually transfected into H1299 cell via lentivirus.The interference efficiency of ULF-siRNA were screened by real-time PCR and Western blotting.Then the most target siRNA was used for apoptosis assay after treatment with etoposide,MTT assay for H1299 cell proliferation,flow cytometry for cell cycle distribution. Results The expression of ULF gene and its protein ULF were down-regulated in H1299 cell when transfected with ULF-siRNA,and ULF-siRNA-1 was the most effective one,which had the highest inhibition rate(80%)of ULF expression.Compared with negative control group,ULF-siRNA group showed an obvious apoptosis after treatment with etoposide,and the inhibition rate of was higher than control group,which was positively correlated with etoposide dose,the difference was statistically significant(P<0.05 ).Flow cytometry showed that compared with the control group,G0/G1 cell cycle in ULF-siRNA group was increased,and S phase cells was decreased,the differences were all statistically significant(P<0.05).Conclusion Down-regulation ULF protein expression through treatment with etoposide can induce apoptosis of non-small-cell carcinoma H1299 cells,and inhibit cell proliferation,which lead to cell cycle arrest.ULF gene may become the new target of gene therapy for cancer.

Conclusion Transplanting ADSCs can improve the antioxidant ability and strengthen the cellular immune function of aging rats.Further more, it can delay the ageing procedure induced by D-galactose in rats.

BACKGROUND:The researches about the effect of retinoic acid on the proliferation of adipose-derived stem cells are rare, and the researches on the testosterone are mainly on the inhibition of cellaging. OBJECTIVE: To study the effects of retinoic acid and testosterone or combination on the cellcycle of adipose derived stem cells. METHODS:Adipose derived stem cells were isolated from adult female Sprague Dawley rats with 2 months age and cultured in vitro til passage 3 adipose derived stem cells, and then the 3rd passage adipose-derived stem cells were performed with adipogenic induction, osteogenic induction and surface marker identification. The cells were divided into six groups:(1) Control group;(2) 10-5 mol/L retinoic acid group;(3) Retinoic acid group;(4) 10-5 mol/L retinoic acid+testosterone group;(5) 10-6 mol/L retinoic acid+testosterone group;(6) Testosterone group. The adipose-derived stem cells in the control group were cultured with Dulbecco’s modified Eagle’s medium+10%fetal bovine serum culture medium, and the adipose-derived stem cells in the other five groups were induced with corresponding dose of retinoic acid and testosterone on the basis of control group. After cultured for 36 hours, the flow cytometry was used to detect the changes of cellcycle. RESULTS AND CONCLUSION:Compared with the control group, cellproportions in phase G 1 of 10-5 mol/L retinoic acid group and 10-6 mol/L retinoic acid group were increased significantly, and the cellproportions in phase S were decreased. Compared with control group, the cellproportion in phase G 1 of testosterone group was significantly reduced, and the cellproportion in phase S was increased. Compared with 10-5 mol/L retinoic acid group and 10-6 mol/L retinoic acid group, cellproportions in phase G 1 of 10-5 mol/L retinoic acid+testosterone group and 10-6 mol/L retinoic acid+testosterone group were reduced significantly and the cellproportions in phase S were increased. Retinoic acid can inhibit the cellcycle of adipose-derived stem cells in phase G 1 , and delay the process of the cellcycle from phase G1 to phase S;while testosterone can promote the cellcycle of adipose-derived stem cells from phase G1 to phase S;the combination induction of retinoic acid and testosterone can accelerate the process of the cellcycle of adipose-derived stem cells from phase G 1 to phase S.

Objective To discuss the correlation between aortic elasticity and coronary artery calcification by CT.Methods Totally 111 patients who were diagnosed of coronary artery disease underwent coronary artery CTA.The images were qualified for aortic elasticity measurement.All patients were divided into calcification negative group (n=43) and calcification positive group (n =68).The calcification positive group was further divided into light,medium,and serious groups according to their calcification scores.The ascending aortic images were reconstructed every 5 ％ R-R intervals.The cross-sectional areas and diameters of aortic in each R-R interval were measured automatically,then diameter variation rate (％ A0),aortic distensibility (A0D),aortic compliance (A0C) and aortic stiffness (A0SI) were calculated to evaluate aortic elasticity.Correlation between aortic elasticity and coronary artery calcification were analyzed.Results ％ A0,A0 D,A0C were lower and A0SI was higher in calcification positive group than those in calcification negative group (all P＜0.05).There was no significant differences in the four reference indexes of aortic elasticity among light,medium,and serious groups in calcification positive group (all P＞0.05).Correlation analysis demonstrated negative correlations between ％ A0,A0 D,A0 C and calcification scores,and a positive correlation between A0SI and calcification scores.Conclusion Aortic elasticity is correlated with coronary artery calcification,and the combination of them will be beneficial for the early diagnosis of coronary heart disease.

Objective To introduce a novel technique of intracolonic shunt procedure used in the anus - preserving operation for acute intestinal obstruction resulted from cancer at low and middle portions of rectum and assess the clinical significance. Methods In total, 81 patients with acute obstruction of low and middle portion of rectum caused by cancer were randomly ( random number) divided into control group and study group. In control group, 42 patients were operated with preventive transverse colonostomy or terminal ileum stoma after low proximal resection of rectum involved in cancer, while 39 patients were operated with intracolonic shunt procedure by using a biodegradable anastomosis ring and a condom placed 5 cm above anastomosis for protection in study group. Results There were no significant differences in sex, age, tumor site, tumor size and the distance from anstomosis to anal-edge between two groups. In both groups, the bowel movement resumed in 2 ~ 5 days after operation (P > 0.05). In study group, the rate of anastomosis leakage was 7.7% (3/39), and leakages were treated with drainage for 7.1 days in average to be healed, and the biodegradable anastomosis ring detached and were discharged in 14 -23 days (17 days in average), and there were no complications of drainage happened. The anastomotic stenosis occurred in three patients (7. 7% ) within 6 months after operation. In control group, 11.9% patients (5/42) had anastomosis leakage and they treated with drainage for 18.2 days in average to get the leakage healed, and 35. 7% patients (15/42) had stoma complications, and anastomotic stenosis happened in 28.6% patients (12/42) within 6 months after operation, and 7. 1% patients need another operation because of severe anastomosis stenosis. There were no significant differences in rate of anastomosis leakage between tow groups ( P > 0. 05), but there were significant differences in drainage days after anstomosis leakage happened and 6 - months anastomosis stenosis between two groups (P<0.05). Conclusions In the anus -preserving operation for acute intestinal obstruction at low and middle portions of rectum caused by cancer , the intracolonic shunt procedure is convenient and safty, and reduces the hazard incurred by anastomosis leakage and anastomosis stenosis compared with classic stoma operation.
