OBJECTIVE:To study the affinity of penehyclidine optical isomers to muscarinic(M)receptor subtypes,and pro-vide reference for revealing the action targets and efficacy selectivity of penehyclidine. METHODS:Homology modeling,molecu-lar docking and other molecular simulation technologies were used to analyze and predict the binding energy of 4 optical isomers to M receptor subtypes and judge its affinity by comparing the binding energy of different optical isomers R1 (3R,2′R),R2 (3R, 2′S),S1(3S,2′R),S2(3S,2′S)with M receptor subtypes M1-M5. RESULTS:All the 4 optical isomers can dock into the ac-tive sites of M receptor subtypes,and different optical isomers showed great differences in the molecular docking with different M receptor subtypes. Penehyclidine isomers showed larger binding energy to M3,the binding energy of 4 optical isomers ranged in 5736.519-5907.143 kcal/mol. The binding energy of R1 to M1 was 1190.041 kcal/mol;while those of other optical isomers to each receptor subtype were lower or negative. CONCLUSIONS:R1 shows the affinity to M1 receptor. And all the 4 optical isomer show the affinity to M3.

Objective To investigate the protective effect of GuanXinShiWeiWan on ischemia reperfusion(I-R) injury rat.Methods 50 Wistar rats were randomly divided into normal group, model group, GuanXinShiWeiWan low ( 0.3 mg/kg ) and high ( 0.9 mg/kg ) dose group and positive group, each had 10 rats.Adopting the model of ischemia reperfusion injury of isolated rat hearts, the contents of SOD,MDA,LDH,CK and Ca2 +-ATP, Ca2 +-Mg2 +-ATP, Na +-K +-ATP in cardiac muscle tissue were tested and compared.Results Compared with model group, GuanXinShiWeiWan significantly improved the activities of SOD、Ca2 +-ATP,Ca2 +-Mg2 +-ATP and Na +-K +-ATP (P<0.05 or P<0.01) in cardiac muscle tissue which injured by ischemia reperfusion, while reducing markedly the contents of MDA,LDH,CK(P<0.05 or P<0.01).Conclusion GuanXinShiWeiWan can profect the cardiac muscle of ischemia reperfusion.

Background To investigate the expression of the early growth response gene-1 ( Egr-1 ) mRNA after focal cerebral ischemia / reperfusion in rats.Methods Ten healthy male SD rats weighing 200 ～ 250 g were used to create model of focal cerebral ischemia. The expression of Egr-1 after focal cerebral ischemia/reperfusion in rats was determined using in situ hybridization and RT-PCR.Results (1) The result of the in situ hybridization: A trace amount of Egr-1 mRNA expressed in the neurons and the glial cells in the sham operated group. The expression of Egr-1 mRNA at the ischemic side increased dramatically following ischemia and reached peaks after 4 hours' reperfusion. Egr-1 expression started to subside following 22 hours' reperfusion and further decreased following 166 hours' reperfusion, which was still significantly higher than that in the sham operated group. (2) The result of RT-PCR: The expression of Egr-1 mRNA at the ischemic side was significantly higher than that in the sham operated group at all time points after ischemia/reperfusion in the rats(P ＜0. 01). Expression of Egr-1 increased 2 h after ischemia and reached the peak 4 h following reperfusion, and then decreased dramatically at 46 h after reperfusion which was still higher than that in the sham operated group (P ＜ 0. 01). As the ischemia/reperfusion period prolonged, the expression of Egr-1 mRNA increased gradually, but still detectable even 166 h following reperfusion. The expression of Egr-1 was significantly higher than that in the sham operated group at all time points (P ＜0. 01).Conclusions The expression of Egr-1 mRNA increase in the neurons and the glial cells after ischemia/reperfusion, which may have protective effects on ischemic brain tissues.

OBJECTIVE:To evaluate the rationality and validity of chemical medicine tablet production equipment cleaning pro-cedure. METHODS:Among several chemical medicines prepared by similar production technology as Metoprolol succinate sus-tained-release tablets,Captopril tablets,Isosorbide mononitrate tablet and Metformin hydrochloride tablet,Metoprolol succinate sus-tained-release tablets had strongest toxicity and were included in validation test. The production equipment was cleaned and disinfect-ed according to cleaning procedure. The point which was most difficult to clean could be wiped and sampled by using the cotton swab method. The detection limit and the limit of quantitation of the residue limits were verified as well as the recovery rate of wip-ing,in order to evaluate whether the results meet the requirements. RESULTS:The cotton swab method is adopted to wipe sample and detect the point which is most difficult to clean. The visible foreign body has not been found in each sampling point. The amount of residual drug is <29.75 μg/cotton bud,and microbial limits are <50 CFU/cotton bud,indicating test items are in line with the standard. CONCLUSIONS:The cleaning method can effectively clean the production equipment,and can effectively pre-vent product contamination and cross contamination to ensure the quality,efficacy and safety of the next batch of products.
