Objective To study the influence of different eyedroping interval on the effects of mydriasis.Methods Divided the selected patients into the experiment group(126 cases) and the control group(128 cases) randomly.Different eyedroping interval were adopted in the different group,and then compared the datum which obtained from 2 groups.Results The diameter of pupils in the experiment group were 7.45 mm and the 7.48 mm respectively after the mydriasis,which in the control group were 6.96 mm and 7.00 mm respectively,the difference between the 2 groups was significant.Conclusion Using eyedrop of tropicamide by every 5 minutes can effective shorten the operation time and can obtain better effects than the routine method.

Objective To design the meta-data scheme for medical records database of traditional Chinese medi-cine.Methods The meta-data scheme for medical records database of traditional Chinese medicine was designed u-sing the MARC meta-data according to the analysis of resources, investigation of literature, networks and users. Results The meta-data scheme for medical records database of traditional Chinese medicine is consisted of 17 fields and 9 parts.Conclusion MARC, as the mata-data criteria, can organize and describe the medical records of tradi-tional Chinese medicine.However, the standards for selection and description of meta-data criteria need to be fur-ther studied.

Objective: To establish the yeast expression system for oncostatin M (OSM). Methods:The cDNA encoding human OSM was inserted into pPIC9K vector and transformed into Pichia pastoris. The correct phenotype of recombinants was screened through MD and MM auxotrophic culture medium. The OSM mRNA transcription in the P.pastoris and molecular weight were identified with Northern blot and Western blot. MTT method was used to test the activity of OSM in inhibiting the growth of human melanoma cells. Results: Established P.pastoris system could accomplish human OSM secreting expression. The recombinant OSM with a 30 000 molecular weight amounted to 70% of the total protein in medium supernatant. The OSM showed an inhibitory effect on the growth of A375 cells in vitro. Conclusions：The P.pastoris system of OSM was proved effective with a high expressing level. The secreted recombinant OSM present in supernatant of culture medium would be easy to be purified. It may lay the foundation for the large-scale preparation of OSM in future.

BACKGROUND:It has been proved that Rhizoma Chuanxiong can promote osteoblast proliferation and differentiation.
OBJECTIVE:To further observe the effects of tetramethylpyrazine (Ligustrazine) extracted from Rhizoma Chuanxiong on osteoblast proliferation and type I col agen expression.
METHODS:Mouse osteoblast cel line MC3T3-E1 was cultured in medium containing 1, 5, 10, 15 and 20 mg/L Ligustrazine, respectively. Osteoblast proliferation was detected by cel counting kit-8 assay, and alkaline phosphatase activity and type I col agen level measured using ELISA method.
RESULTS AND CONCLUSION:Different concentrations of Ligustrazine al significantly promoted the osteoblast proliferation and type I col agen level compared with the blank control group (P<0.005). The activity of alkaline phosphatase in al Ligustrazine groups except 15 and 20 mg/L groups was significantly higher than that in the blank control group (P<0.005). These results show that Ligustrazine isolated from Rhizoma Chuanxiong can effectively promote the osteoblast proliferation and type I col agen expression, with the optimum concentration of 10 mg/L.

Objective To investigate the preventive and therapeutic effectiveness of Yisheng herbal injection against chronic allograft nephropathy in rats.Methods Renal transplantation was performed from SD to Wistar closed colony strain rats. Before the transplantation, the kidney was preserved in 0- 40 ℃ heparin sodium chloride solution for one h. The rats were divided into 4 groups: Group A only received CsA 10 mg/kg every day; Groups B, C and D received low dose of Yisheng+CsA, high dose of Yisheng+CsA and CsA+MMF, respectively. Blood creatinine, pathological changes of the renal grafts and the expression of transforming growth factor ?1 in transplanted renal tissues were observed 4, 8 and 12 weeks after operation.Results After the transplantation, the serum creatinine level in group A was significantly higher than in groups B, C and D ( P

ObjectiveTo observe the clinical effect of Chinese medication plus warm needling in regulating the hypothalamo-pituitary-ovarian axis (HPOA) for anovulatory infertility.MethodThe relevant clinical data of sixty-seven women with infertility were comprehensively analyzed, to summarize the risking factors for anovulatory infertility, and then the subjects were randomized into an observation group and a control groupby their visiting sequence. The control group was intervened by orally taking Bushen Tiaojing Cupailuan (tonifying kidney, regulating menstruation, and promoting ovulation) decoction, while the observation group was by warm needling in addition to taking the same decoction. The clinical efficacies, growth of endometrium, and size of follicle were compared between the two groups.ResultWarm needling plus Bushen Tiaojing Cupailuan decoction produced a positive effect in treating anovulatory infertility, andthe pregnancy rate of the observation group was significantly higher than that of the control group (P<0.05).ConclusionThe effect produced by warm needling plus Bushen Tiaojing Cupailuan decoction has a comparatively high clinical value.

Objective: To explore the influence of Aiweixin on cardiocyte apoptosis of myocardial ischemia-reperfusion injury in rats. Methods: Thirty male Wistar rats, 200-250g weight, were divided into 3 groups randomly: sham-operation group, Ischemia-reperfusion injury group (I/R) and Aiweixin preconditioning group, each group had 10 rats. The model of myocardial ischemia-reperfusion injury was established. The protein expressions of Bcl-2, Bax and Caspase-3 were studied by Immunohistch emicalstaining. Results:The protein expressions of Bax and Caspase-3 increased and Bcl-2 decreased signifi cantly (P

Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.
