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.

Objective To observe morphological character of posterior arch of Atlas and lamina of axis,as well as provide anatomical basis to design special guiding device for the operation of upper cervical posterior fixation with Atlas titanium cable so as to make the operation safe and easy.Methods The posterior arch of Atlas and lami- na of axis were observed and measured in 100 adult dry Atlas and axis specimens,then special guiding devices were designed based on the anatomical data.Results (1)The posterior arch of Atlas was thin with a fan-shape section, whose inner plane descended from back to inside and the lamina of axis was stronger and thicker than posterior arch of Atlas,with a vertical inner plane and a ridge near the lower edge.(2)The special guiding device for posterior arch of Atlas should be designed with a bend head as well that for lamina of axis should be designed with a round head. They were used in 61 operations which became safer and easier.Conclusion The operation of upper cervical posteri- or fixation with Atlas titanium cable would be safer with the help of special guiding devices which were designed based on the anatomical character.

Objective:To establish the method of determination of the contents of Danshensu and Protocatechuic aldehyde in Huoxue Mixture simultaneously by RP HPLC.Methods:The determination was carried out with Inertsil ODS column. The mobile phase consisted of methanol 0.5% HAc (22∶78) and UV detection wavelength was 280nm. Results:The average recovery of standard addition were 96.7%, RSD =1.12% ( n =5) for Denshensu, and 97.0 %, RSD =1.53% ( n =5) for Protocatechuic aldehyde, There was a good linear relationship between the absorption area value and the concentration in the range of 1.25～10?g for Deshensu and 0.25?g～2.0?g for Protocatechuic aldehyde.Conclusion: The method is simple, acurate, reproducible and can be used for content determination of Huoxue Mixture.

Objective:To establish the determination of the contents of ferulic acid and paecniflorin in Huoxue Mixture Radix Salviae Miltiorrmizae, Radix Angelicae sinensis, Radix Paeoniae Rubra cortex Moutan, Radix Astragali and caulis Spatholobi simultaneously by HPLC.Methods:The determination was carried out with ZORBAX *ODS column. Chromatographic condition of ferulic acid: the mobile phase consisted of methanol 1%HAc (42∶58) and UV detection wavelength was at 313nm. Chromatographic condition of paecniflorin: the mobile phase consisted of methanol water (25∶75) and UV detection wavelength was 230nm.Results:There was a good linear relationship between the absorption peak area and the concentration in the rang of 0.125～1.0?g for ferulic acid and 0.25～2.0?g for paecniflorin, respectively.Conclusion:The method is simple, acurate, reproducible and can be applied for content determination of Huoxue Mixture.

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.

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 investigate the clinical and pathological features of Henoch-Sch?nlein purpura nephritis (HSPN) in children. Methods The clinical and pathological data of 242 children with HSPN admitted from January 2009 to January 2014 were retrospectively analyzed. Results The most common clinical type was proteinuria and hematuria (135 cases, 55.79%). The mainly pathological types were typeⅡandⅢ. The distribution of pathological types was statistically signiifcant between different clinical types (P=0.000). The patients with normal urine test had the lowest pathological grade. The patients with isolated hematuria and proteinuria mainly had pathological typeⅡ. The patients with hematuria and proteinuria mainly had pathological typeⅢa. The patients with nephrotic syndrome mainly had pathological typeⅢb. The length of the courses at renal biopsy was not statistically signiifcant among different clinical types (P>0.05) and pathological types (P>0.05). The deposition of immune complex in kidney was not statistically signiifcant among different pathological types (P>0.05). The levels of IgA, C3, and platelet count were not statistically signiifcant among different clinical and pathological types (P>0.05). Conclusion The clin-ical classiifcation is related to the pathological grade in children with HSPN.
