Objective To investigate the diagnostic value of color doppler transvaginal scan for patients with ectopic pregnancy. Methods Transvaginal scan and transabdominal scan were used to inspect 109 cases that were clinically doubted as early ectopic pregnancy. 126 cases only received transabdominal scan were as control group. Results Through transvaginal scan,35 cases were found as early unruptured ectopic pregnancy after they stop men-stru-ation about 35 to 42 days. The inspected time of the other 74 cases and control cases was post-poned obviously. All cases were compared with laparoscopy or skive belly operation and got the consilient rate of 97%. And the inspected time was earlier for 11. 3 days than the contrel group. This was a notable discrepancy (P < 0.01). Conclusion Transvaginal scan could improve the inspected rate for the early ectopic pregnancy greatly. It had more value than other methods,so it was worth being utilized widely.

Objective To investigate the impact of renal function and insulin resistance on serum total homocysteine(tHcy) levels in aged diabetic patients with nephropathy. Methods Serum tHcy, blood glucose, lipids, renal function, serum insulin were measured for 98 elderly patients with type 2 diabetes and 36 normal control subjects. Results (1) Serum tHcy levels were significantly higher in diabetic group than in control group [(17.2?7.6) ?mol/L vs (9.4?3.5)?mol/L,P
