Objective To perform literature search and review on the controversial relationship between therapies of hyperthyroidism due to Graves'disease(GD)and the course of Graves'ophthalmopathy(CA)).Methods We searched the database of MEDLINE(1966-2006.3),EMBASE(1984-2005),Cochrane Library(2006 No.1),CBMdisc(1978.1-2006.4)and CNKI(1994-2006).The methodological quality of the studies selected for review was assessed according to the quality assessment criteria suggested by the Cochrane systematic review guideline.Meta-analysis was performed by RevMan 4.2 software.Results Eight studies were included in the systematic review.Meta-analysis showed that there was statistically significant difference between 131I and other forms of therapy[surgery or antithyroid drugs(ATD)](test value:2.31,5.97,3.70,5.55;all P＜0.05)in aggravation of exophthalmos and symptom improvement in patients without receiving thyroxine during the early stage to prevent hypothyroidism.However,there was no statisti cally significant differenee in the above relationship between surgery and ATD therapy in those patients already receiving thyroxine supplement(test value:0.27,0.99;all P＞0.05).There were not yet any studies on the impact between early prevention of hypothyroidism after 131I therapy and GO.Conclusions Based on meta-analysis on literature data,if early measures are not performed to prevent hypothyroidism after 131I therapy,it may induce or aggravate GO more frequently than ATD or surgical treatment.Symptomatic relief of GO after 131I therapy is also less effective than the other 2 forms of therapy.Therefore.131I therapy should be delivered carefully in those patients with GO.

Expression of endogenous ouabain in placenta and the concentrations of serum ET-1 and NO were examined in 30 patients with hypertensive disorder complicating pregnancy (HDCP) and 30 healthy pregnant women to investigate the effect of endogenous ouabain on HDCP. Compared with the healthy pregnant group, the expression of endogenous ouabain dramatically increased in the HDCP groups (P<0.01). There was a significantly positive correlation between the expression of endogenous ouabain with ET-1 (r=0.5567, P<0.01), while the correlation of endogenous ouabain and NO was significantly negative (r=-0.6895, P<0.01). As expected, the correlation between ET-1 and NO was negative (r=-0.7796, P<0.01). ET-1 concentrations of maternal and cord sera in HDCP groups were significantly higher in comparison with healthy pregnant group (P<0.01). On the contrast, NO concentrations were much lower in the maternal and cord sera of HDCP groups as compared with healthy pregnant group (P<0.01). Our data suggest that endogenous ouabain is directly involved in the nosogenesis of HDCP, with accompanying decreased NO and the elevated of ET-1.

Objective To observe the expression and the distribution of Netrin-1 in the spastic and normal segment of colon in patients with Hirschsprungs disease (HD) and investigate the relationship between Netrin-1 and development of HD.Methods Colon specimens of 36 cases with HD were selected for this study.Normal segment of colon served as the control group,while the spastic segments of colon as the lesion group.Immunohistochemical staining was applied to detecte the expression and the distribution of Netrin-1.Results Immunohistochemical staining showed that the expression of netrin-1 was positive in the intestinal muscular layers (longitudinal muscle,circular muscles),myenteric ganglias and mucosal layers in the control group.However,the expression of Netrin-1 was also positive in muscular layers and mucosal layer in the lesion group.There was no significant difference in the expression intensity of Netrin-1 between the two groups (P ＞0.05).Conclusion The expression of Netrin-1 in both the control group and the lesion group may indicate that netrin-1 have no significant correlation with genesis of HD.

Objective To evaluate the efficacy and safety of intense pulsed light and diode laser for axillary hair removal. Methods Clinical trials on 61 persons using intense pulsed light and diode laser to depilate axillary hairs were conducted. 36 persons were treated by IPL and 25 persons by diode laser.Treatments were carried out in three times at 8-week intervals, and a final assessment was made 3 months following the third theatment. Results Both IPL and diode laser reduced the hair count substantially! the IPL group effective rates were 80. 6 % and the diode laser group, 76. 0 %. They had no statistical significance was (P>0. 05)). Conclusions Intense pulsed light and diode laser are effiective and safe for hair removal.

In order to treat or prevent portal vein metastases of liver cancer, intraportal chemotherapies were carried on in 18 and in 42 patients with and without portal vein thrombosis. The agents used were Pharmorubicin 30 mg, Mitomycin—C 8 mg and 5—Flurouracil 500 mg. The results showed that the incidence of portal thrombosis in preventive group (19.04％) was lower than that in control group (38.9％) (P

Objective To establish a self-made chiral column for enantiomeric separation of salbutamol. Methods We used different concentrations of acid,alkali additives in the polar phase flow for enantiomers separation of salbutamol by using 3, 4-dichlorophenyl isocyanate vancomycin chiral column, and discussed the chiral recognition mechanism. Results The ratio of acid to alkali additive in the mobile phase was 0.01%:0.01% (V/V), the flow rate was 1ml/min, the column temperature was 25℃, and the best separation of enantiomers of salbutamol was obtained,the selective factor was 1.16, the separation degree reached 1.41. Conclusion Self-made 3, 4-two chlorophenyl isocyanate vancomycin chiral column is effective for salbutamol separation, and it can be as a reference for developing other similar chiral stationary phase.

We summarized our accumulated clinical and teaching experiences and explored the regularity of acupuncture needling and teaching. It is of great importance in pressing hand during inserting needle. Stroking and pressing are two crucial parts which deserve more attention, and seldom useage of pressing hand should be abolished. Operating hand needs practice before inserting needle, while it should fully relaxed during inserting. Blending "touching", "stretch" "gathering" "erupting" and "advancing" in single moment, applying appropriate dynamic mode of inserting needle such as "join 3 forces as one" "3 points in a line" expertly and naturally. In addition, enough attention should be paid on "altering direction" and "shifting point". Inserting deftly and powerfully, no/slight sensation, deqi when inserting needle are the highest reflection as an acupuncturist.
