Objective To analyze the oral glucose tolerance test (OGTT) curve characteristics in Chinese women with gestational diabetes mellitus (GDM) or gestational impaired glucose test (GIGT) and to evaluate whether omission of the third-hour plasma glucose measurement of the OGTT could alter the sensitivity of the diagnosis on GDM,and whether there is a close relationship between plasma glucose values of 50 g glucose challenge test (50 g GCT) or OGTT and insulin therapy. Methods A retrospective analysis on medical records of 647 cases with GDM from January 1,1989 to December 31,2002 and 233 cases with GIGT were performed. Among 647 cases of GDM,535 were diagnosed by 75g OGTT. All OGTT (535 with GDM and 233 with GIGT) results were evaluated. Results There were 112 cases of GDM diagnosed by elevated fasting plasma glucose without OGTT performed. Of 535 cases of GDM diagnosed by OGTT,49.2% (263/535) women were with fasting plasma glucose value ≥5.8 mmol/L;90.1% (482/535) women with 1hr plasma glucose values ≥ 10. 6 mmol/L;64.7% (359/535) were with 2 hr plasma glucose levels ≥9.2 mmol/L. There were only 114 cases (21.3%) with abnormal 3 hr plasma glucose levels among 535 women with OGTT,and when 3 hr plasma glucose reached cutoff value,49.1% the other three values of OGTT were abnormal and 34.2% with the other two values of OGTT. Among 233 women with GIGT,only 4 cases with the abnormal 3 hr plasma glucose. We also investigate use of the glucose values for the first 2 hours of OGTT only missed 19 cases of GDM,still discriminated 516 cases. Omission of the third -hour glucose tolerance test value only resulted in failure to diagnose 2.9%(19/647) of GDM cases and 1.72%(4/233) of GIGT cases in Chinese women. Plasma glucose levels ≥11.2 mmol/L following 50 GCT were highly associated with GDM necessitating insulin therapy (75.4%). An elevated fasting plasma glucose level was also associated with insulin therapy (59.7%).Conclusion Omission of the third -hour glucose tolerance test value still yielded a higher sensitivity of 97.1%(628/647) of GDM cases and 98.2%(229/233) of GIGT cases in Chinese women. It is practicable to omit 3-hour post -glucose ingestion value of the OGTT in Chinese women. Plasma glucose levels ≥11.2mmol/L following 50g GCT indicated 75.4% cases of GDM necessitating insulin therapy.

The optimal extraction technology of Xinzhi nasal drops was as follow as 10-fold 80% ethanol,extracting twice,1 h every time. In verification test,the average content of imperatorin was 0.078%(RSD=2.01%,n=3),and extract yield was 10.80%(RSD=1.85%,n=3). CONCLUSIONS:HP-β-CD shows good solubilization effect on the 1,8-oxido-p-menthane in volatile oil of magnoliae flos,and the optimized extration technology for Xinzhi nasal drops is feasible.

Objective:To investigate the influence of practolol oral liquid on the rat model of water load. Methods: Totally 70 qualified rats were selected and randomly divided into seven groups with 10 ones in each, and the rats were with intragastric administra-tion respectively by practolol oral liquid (20,10 and 5 ml·kg-1 , respectively diluted 20 ml, 10 ml and 5 ml to 20 ml liquid with dis-tilled water), furosemide tablets suspension (0. 033 5 mg·ml-1), Qiliqiangxin capsule suspension(0. 03 g·ml-1) and distilled wa-ter with the same voulme( model) . The rats were placed in metabolism cages. After the administration, the urine volume was recorded every 1 h for 5 hours, the total volume of urine was collected during the 5 h, and the concentration of Na+, K+ and Cl- in the urine was measured. Results:Compared with that in the blank group, the urine volume in 2 h, 3 h and 5 h after the administration in the model group was significantly increased(P<0. 01), the total urine volume was also increased significantly(P<0. 01), the K+ con-centration was significantly reduced in the urine(P<0. 05), and there was an increasing trend of Na+ and Cl- concentration in the u-rine, which indicated that the water load model was made successfully. Compared with the model group, furosemide could significantly increase the urine volume in 1 h, 2 h, 3 h, 4 h and 5 h after the administration, and the total urine volume was increased as well ( P<0. 01). Qiliqiangxin capsule group could significantly increase the K+ concentration in the urine(P<0. 05), and furosemide could significantly reduce the K+ concentration in the urine (P<0. 05). High-dose practolol oral liquid could significantly increase the urine volume in 5 h after the administration and the Na+ and Cl- concentration(P<0. 01), mid-dose practolol oral liquid could significantly increase the urine volume in 3 h and 5 h after the administration and the total urine volume (P<0. 05), and improve the Cl- concen-tration in the urine (P<0. 05), and the Na+ and Cl- concentration in low-dose practolol oral liquid group was decreased significantly (P<0. 01). Compared with Qiliqiangxin capsule group, the high, medium and low-dose practolol oral liquid showed no significant in-fluence on the urine volume(P>0. 05), high-dose practolol oral liquid could significantly increase the Na+ concentration in the urine (P<0. 01), medium and low-dose practolol oral liquid could significantly increase the Na+ concentration in the urine(P<0. 05), low-dose practolol oral liquid could significantly reduce the K+ concentration(P<0. 01), high and medium-dose practolol oral liquid could significantly increase the Cl- concentration in the urine (P<0. 01), and low-dose practolol oral liquid could significantly reduce the Cl- concentration in the urine (P<0. 01) . Compared with the high-dose practolol oral liquid group, the influences of medium and low-dose practolol oral liquid showed no significant difference in the urine volumes(P>0. 05), however, the total urine volume could significantly increase(P<0. 01), and the medium and low-dose practolol oral liquid could significantly reduce the Na+ and Cl- con-centration in the urine(P<0. 01). Conclusion:Practolol oral liquid has significant diuretic effect in a dose-dependent manner.
