Objective To investigate the possibility and utility of metformin alone or in combination with fosinopril to reduce blood pressure in patients with essential hypertension.Met hods A total of 140 cases of non-diabetic essential hypertension with hyperinsulinemia were recruited and randomly assigned to two groups: a group of 68 treated with metformin 500 mg tid and a group of 72 treated with fosinopril 10 mg qd.The duration of the treatment was 8 weeks.Combination therapy with the two drugs was used after 4 weeks of treatment if needed.If the target goals of systolic blood pressure (SBP) < 140 mm Hg (1 mm Hg =0.133 kPa) and /or diastolic blood pressure (DBP) <90 mm Hg were not attained 4 weeks, combination therapy with two drugs was used in either group in the next 4 weeks.The changes of blood pressure and insulin sensitivity of the two groups were observed before and after treatment.Results (1) After 4 weeks of treatment, SBP in metformin group and fosinopril group decreased by ( 13.0 ± 1.2) mm Hg and (15.4 ± 1.4) mm Hg, and DBP decreased by (9.0 ± 1.0) mm Hg and ( 10.4 ± 1.1 ) mm Hg respectively.After 8 weeks of treatment, SBP in metformin group and fosinopril group decreased by (17.8 ± 1.5) mm Hg and (20.9 ± 1.5) mm Hg, and DBP decreased by (13.2 ±0.9) mm Hg and (15.3 ± 1.1) mm Hg respectively.There was no significant difference in the decline of blood pressure between the two groups (P >0.05).The rates of combination therapy were both 54% in the two groups.(2) Fasting insulin as well as 30 min and 120 min insulin levels after oral glucose tolerance test and insulin area under the curve in the metformin group were significantly reduced after 4 and 8 weeks of treatment as compared with those of baseline(P < 0.05 and P < 0.01 ) .In the fosinopril group, however, they decreased only after 8 weeks treatment (P < 0.05).The insulin action index in the metformin group was higher than that in the fosinopril group after 4 weeks of treatment (P <0.05) ,but there was no significant difference between the two groups after 8 weeks of treatment (P > 0.05).Conclusion Metformin and fosinopril have similar antihypertensive effect and a good synergy in essential hypertension with hyperinsulinemia.

Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.
