Background Some drugs with inhibitory effect on the proliferation of lens epithelial cells have a limiting application in clinic because of their adverse response.To screen the effective and less side-effect drug for supressing LECs growth is very inportant for the prevention and treatment of after cataract.Objective This study was to explore the effects of docetaxel on LECs growth and compare its role with epirubicin hydrochloride,pirarubicin hydrochloTide and rahitrexed.Methotis Immortalized human LECs line (SRA01/04) were cultured and passaged.Different concentrations of docetaxel,epirubicin hydrochloride,pirarubicin hydrochloride and rahitrexed were added into the medium respectively for 24.48 and 72 hours.The proliferation of LECs was detect by M1Yr.Flow cytometry analysis Was used to analyze the influence of different concentrations of docetaxel on cellular cycle at 48 hours after addition of docetaxel,and Annexin V-FITC/PI marking method was used to assesse the apoptosis of LECs under the action of docetaxel.Expression of bcl-2 protein in LECs Was evaluated by Westeru blot. Result The growth rate of LECs Wag 100%in 8-519 pmol/L doeetaxel groups with the normal cell shape.Majority of abnormal cells and low growth rate were found in 66 nmoVL docetaxel group at 48 and 72 hours.The IC50 of docetaxel was lowest in 48 and 72 hours in docetaxel group in comparison to epirubicin hydrochloride and pirarubicin hydrochloride. However,no evident inhibition on LECs growth in 23.22-523.56 μmol/L of raltitrexed.At 48 hours,the percentage of LECs in G2/M phase increased as the asccnte of concentration of docetaxel,showing a significant difference among 4 groups(F=2633.05,P＜0.01).The percentage of early apoptotic cells increased to 22.4%(χ2=20.00,P＜0.01) and 27.9%(χ2=42.68,P＜0.01)from normal control 3.1% at 48 hours after LECs exposed to 8.3 nmol/L and 266 nmol/L docetaxe.The expression of bcl-2 protein in LECs was obviously weakened after addition of docetaxel,especially 8.3 nmol/L docetaxel group. Conclusion Docetaxel,epirubicin hydrochloride and pirarubicin hydrochloride can inhibit the proliferation of human LECs in vitro.But there is no supression on LECs growth inraltitrexed.Docetaxel is proved to have a strongly arrested effect on the proliferation of LECs in comparison with epirubicin hydrochloride and pirarubicin hydrochloride and play its role at concentration-and time-dependent manner.

Choosing the right solvent and timely use is the basis of rational drug use and the most direct and efficient way to improve the safety of traditional Chinese medicine injections. This study aimed to evaluate the influence of solvent and drug preparation time on Shuanghuanglian injection inducing pseudo-allergic reactions with mouse mode. The two tests were carried out: (1) Comparative experiment between different solvent: Shuanghuanglian injection preparation to the appropriate concentration with 0.9% sodium chloride injection and 5% dextrose injection, mixed with Evans blue, at one time intravenous injected into mice, 30 minutes later, the mouse ears vascular permeability were observed and compared. (2) Comparative experiment among different preparation time: placed 10 min, 2.5 h, 6 h and 24 h after Shuanghuanglian injection were prepared and then to detect the pseudo-allergic reactions in mice using the same methods as in (1). The results showed that there was no significant difference in the pseudo-allergic reactions in mice which induced by the same dose of Shuanghuanglian injection, respectively with 0.9% sodium chloride injection and 5% dextrose injection preparation, and with the extension of preparation time, the degree of pseudo-allergic reactions of Shuanghuanglian injection was gradually severe.

To evaluated the pseudo-allergic reactions of cordate houttuynia, pulse-activating and Qingkailing injection in mice, the ICR mouse were divided into different test groups, then were intravenously injected with three traditional Chinese medicine injections, positive control compound 48/80 and physiological saline as normal control. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. At the same time, the mechanisms of the traditional Chinese injections' pseudo-allergic reactions was studyed. ICR mice were injected with the test substances as above without EB, blood in a part of mice were collected after 5 min, and the level of histamine in the plasma were measured. Blood in the other part of mice were collected after 30 min, and the level of VEGF, TNF-α and IL-10 in the serum were measured. The reasults showed that except the cordate houttuynia injection, pulse-activating injection in 1. 5 times clinical concentration and Qingkailing injection in 3.3 times clinical concentration caused mild pseudo-allergic reactions mainly for vascular permeability, no pseudo-allergic reactions occurred when the concentration of the two injections was below the concentration metioned above; 5 minutes after intravenous injection of the three TCM injections into ICR mice with the highest dose, the levels of histamine in plasma of pulse-activating injection and Qingkailing injection groups were increased significantly, 30 minutes later, the levels of VEGF, TNF-α and IL-10 in the serum of all groups were no significant change compared to normal group. The mouse of pulse-activating and Qingkailing injection groups showed inflammatory changes in ear and lung tissues. It can be conluded that when the dose or concentration increased to a certain extent, pulse-activating and Qingkailing injection could induce pseudo-allergic reactions on ICR mice, the increased histamine realease maybe the main reason for pseudo-allergic reactions of the two traditional Chinese medicine injections. In addition the author preliminary thought that inflammatory mechanisms leading to hyperpermeabilities were the main reason of the traditional Chinese medicine injection's pseudo-allergic reaction.

OBJECTIVETo study the effects of Shibao Powder on the expression of b-FGF and TGF-beta 1 in granulation tissues of rabbit models with soft tissue injuries, so as to explore mechanism of external Chinese drugs for repairing of soft tissues in molecular levels.

METHODSThe rabbit models were established by classical method of full-thickness skin wounds. After 8% sodium sulfide was used and routine disinfection completed, intra-peritoneal anaesthesia was adopted. The skin was cut to expose gastrocnemius muscle, and imcomplete sharp dissection was made near the tendon insertion. The length of the incision was 0.8 cm and the width was 0.4 cm. The rabbits in the experimental group were treated with spread of Shibao Powder at the wound; the rabbits in clean group were treated with routine dressing changes and disinfection; and the rabbits in the control group were treated with dressing changes only. The granulation tissues in different stages were collected and observed with high power microscope. The expression of Transforming Growth Factor-beta 1 (TGF-beta 1) protein and b-FGF protein in wound tissues were detected using StreptA-ridin-Biotin-Complex (SABC) method.

RESULTSThe results showed that the expression of b-FGF protein had significant differences among 3 groups at the 6th day after trauma (P<0.05). The TGF-beta 1 protein expression also had significant differences among 3 groups at the 10th and 14th days after trauma (P<0.05). At the same time, the growth states of granulation tissues had difference among 3 groups at the same trauma stage, and within the same group among different trauma stages.

CONCLUSIONThis experimental study shows that Shibao Powder is effective to promote the repair of soft tissues after trauma by stimulating production of endogenous growth factor from cells in wound.
