Fifteen min after adding nimodipine 50 ?mol/L, the contractility of the left atrial muscle decreased from 100 % of control to 55.5 +4.2 o/o and its inhibitory effect was equal to the effect of verapamil (25 ?mol/L ) . Nim at the same concentration inhibited strongly the positive staircase phenomenon but could not reverse it into the negative staircase phenomenon as verapamil 25 ?mol/L did. The same concentration of Nim suppressed significantly the post rest contraction. On the contrary, the post rest contraction was not affected by verapamil at 25 ?mol/L. In addition, Nim 50 ?mol/L reversed or prevented significantly the ouabain-induced arrhythmias in isolated left atria. These results suggest that the negative ino-trbpism of Nim may be related not only to the inhibition of Ca2 + influx to the cells and also to the decrease of the intercellular Ca2+ release and that Nim might present the possibility in treating arrhythmias or other heart disease

Objective: To express and purify paired immunoglobin-like type 2 receptor beta (PILRβ) and prepare the polyclonal antibody against its protein. Methods: The PILRβ cDNA was amplified from the total RNAs extracted from human peripheral blood cells by RT-PCR and was cloned into pET-32a vector. The vector harboring PILRβ gene was then expressed in E. coli by IPTG induction and the product was purified by Ni2+-NTA affinity chromatography. Polyclonal antibody was prepared by immunizing rabbits with the purified protein. The titer and specificity of the antibody were examined by ELISA and Western blot, respectively. Results: Highly purified PILRβ protein (Mr 42 000) was obtained. The prepared polyclonal antibody was highly specific and had a titer of 1:10 000. Conclusion: PILRβ gene is successfully cloned and the purified PILRβ protein is expressed. Polyclonal antibody against PILRβ(with high titer and specificity) is successfully obtained, which provides a basis for further study on PILRβ.

Objective To observe the clinical efficacy of acupuncture plus auricular point sticking in treating polycystic ovary syndrome (PCOS). Method A total of 80 PCOS patients were randomly divided into a treatment group of 40 cases and a control group of 40 cases. The treatment group was intervened by acupuncture plus auricular point sticking, while the control group was intervened by acupuncture only. The clinical efficacy was observed in the two groups after 3 treatment courses. Result The menstrual condition and basal body temperature (BBT) were compared in the two groups before and after the treatment. The menstrual condition and BBT in the treatment group were significantly improved (P<0.01); the menstrual condition was improved (P<0.05) and the BBT condition was significantly improved in the control group (P<0.01). The total effective rate was 82.5% in the treatment group, significantly different from that in the control group (P<0.05). Conclusion Acupuncture plus auricular point sticking can produce a satisfactory efficacy in treating PCOS.
