Chinese Journal of Primary Medicine and Pharmacy 2008;15(6):885-886
Objective To study the effect of acupuncture and medication on plasma ealcitonin gene-related peptide(CGRP) levels in patients with acute cerebral infarction. Methods 90 patients with simple obesity were ran-domly divided into acupuncture and medication group( n = 45) and medication group( n = 45 ). All patients were ex-amined the plasma level of CGRP to observe clinical curative effect before and after 1 month treatment. Results The total effective rate of acupuncture and medication group 91.1% (41/45) was significantly higher than that in medication group 77.8 % (36/45) (P < 0.05) ; after treatment the plasma level of CGRP in two groups were signifi-candy higher than those before treatment(P < 0.05) , acupuncture and medication group was significantly higher than that in medication group (P < 0.05). Conclusion Acupuncture in combination with drug could cut down nerve cell damage, and it may be significantly related to levels of CGRP in patients with acute cerebral infarction.

Chinese Pharmacological Bulletin 2010;26(3):329-333
Aim To observe the effect of Ginkgo biloba extract 50(GBE50)on L-type calcium current and cytosolic[Ca~(2+)]_i in ischemic guinea pig ventricular myocytes.Methods Single ventricular myocytes were isolated by enzymatic dissociation. I Ca-L was recorded by whole-cell patch clamp technique in voltage clamp mode.[Ca~(2+)]_i was detected by laser confocal micros-copy and represented by relative fluorescent intensity (FI).Results During ischemia, the peak Ca~(2+) current was reduced, and the I-U curve of I Ca-L was shifted upward.50 mg·L~(-1) GBE50 reversed the change induced by ischemia(n =6, P >0.05).After perfusing ischemic solution for 12 min, intracellular calcium concentration was increased(n =10, P <0.01).After perfusion with ischemic solution containing 50 mg·L~(-1) GBE50, the increase of intracellular calcium concentration was markedly inhibited(n =10, P >0.05).Conclusion GBE50 can reverse the decrease of I Ca-L and partially inhibit calcium overloading during ischemia.

Objective To observe the effects of ischemic preconditioning of hindlimb (HIP) on the expressions of heat shock protein70 (HSP70) in spinal cord of rats after spinal cord injury (SCI). MethodSprague Dawleys rats were randomly( random number) divided into three groups (20 rats in each group).In sham injury group, rats received laminectomy without SCI; while in the SCI group, rats received traumatic SCI. In HIP group, rats received HIP 8 h before SCI. The SCI animal models were made by using modified Allen's weight-drop device (50 g·cm) on L3-L4 vertebrae. HIP was induced by compressing the two lower limbs of rats alternately with a tourniquet for three cycles of ten-minute ischaemia followed by ten-minute reperfusion. Rats were sacrificed 24 h and 48 h after injury separately. The protein and mRNA of HSP70 of involved spinal cord segments were determined by using RT-PCR, hybridization in situ and immunohistochemistry. Results There was weak expression of HSP70 mRNA in rats of sham injury group, and sporadic positive cells in spinal tissue were found by using immunohistochemistry. The expressions of HSP70 mRNA 24 h and48 hours after SCI in HIP group[(22.18±3.69) and (14.15 ±4.18)] were higher than those in SCI group[(13.97±4.46) and ( 8.73 ± 3.55 )], and the differences were statistically significant (F=16.06, P = 0.005 and F = 7.43, P = 0. 028). The protein levels of HSP70 24 h and 48 hours after SCI in HIP group [(16.71±4.02) and (9.85±2.20)] were higher than those in SCI group [( 14.85 ± 3.73)and (8.78 ±2.05)], and the differences were statistically significant (F =90. 13, P =0.032 and F=34.70, P = 0. 036). Conclusions HIP can increase the transcription and expression of HSP70 in spinal cord of rats following SCI and may have the protective effects on neural tissue.

Anthrax is a malignant infectious disease caused by Bacillus anthracis spores,after entering the host Bacillus an-thracis produces and releases anthrax toxin,which is the main cause leading to death of the host. The anthrax toxin is composed of two enzymatically active components:lethal factor(LF)and edema factor(EF),and one shared receptor binding and translocation com-ponent:protective antigen(PA). PA combined with LF is called lethal toxin(LeTx),while PA combined with EF called edema toxin (EdTx). Currently,the main drugs for treating anthrax are antibiotics,but antibiotics can only kill part of anthrax spores and bacte-ria,and cannot inhibit the activity of anthrax toxin. So it is necessary to develop novel drugs for inhibiting anthrax toxin. This review summarizes the evolution of small-molecule inhibitors of anthrax toxin respectively targeting PA,LF and EF.
