AIM　To investigate effect of urotensin Ⅱ (UⅡ)on proliferation of aort a smooth muscle cells （ASMC）of rat and study the signal transduction pathway o f it. METHODS　In cultured ASMC of rat, UⅡ was used to stimulate proliferation of these cells and levels of ［3H］-TdR incorporation were used to evaluate the speed of DNA synthesis, and different inhibitors were used to s tudy the action of different signal transduction pathway of mitogenic effect of UⅡ on VSMC. RESULTS　1×10-9～1×10-7 mol*L- 1 UⅡ caused marked concentration-dependent increasing of ［3H］-TdR i ncor poration of ASMC. ［3H］-TdR incorporation of 1×10-9,1×10-8 and 1×10-7 mol*L-1 UⅡ were 22%（P<0.05）, 57%（P<0.01）and 65%（P<0.01）higher than control. Nicardipine, H7, W7 and PD98059 , which are inhibitors of calcium channel, PKC, CaM-PK and MAPK respectively, inhibited the effects of UⅡ obviously, with the inhibitory rate by 55%（P< 0.01）, 27%（P<0.01）,18%（P<0.05）and 16%（P<0.05）respectively . CONCLUSION　UⅡ is a strong mitogen for VSMC and the mitogenic e ffect of UⅡ is probably mediated by Ca2+, PKC, CaM-PK and MAPK signal tr ansduction pathway.

OBJECTIVETo observe the effect of Ningdong Granule (NG) on serum levels of interleukin-12 (IL-12) and tumor necrosis factor-alpha (TNF-alpha) of children patients with Tourette's syndrome (TS).

METHODSTotally 90 TS children patients were randomly assigned to the NG group, the NG + Tiapride group (abbreviated as the combined treatment group), and the Tiapride group, 30 in each group. Besides,another 30 healthy children were recruited as the healthy control group. Patients in the NG group were treated with NG (consisting of all gastrodia rhizome, Codonopsis pilosula, Ophiopogon japonicus, white peony root, Rhinocerotidae, oyster, earthworm, licorice root, etc.), one dose daily, administered by dissolving it in boiled water, taken in two portions in the morning and in the evening respectively. Patients in the Tiapride group took Tiapride Tablet, 50 -100 mg each time, twice daily. The dosage was adjusted according to individual difference and changes of pathogenic conditions. The maximal dosage was 300 mg per day. Those in the combined treatment group were treated with equal dose of NG and Tiapride Tablet in combination. The treatment course was 3 months for all. Changes of pathogenic condition before and after treatment were assessed by Yale global tic severity scale (YGTSS). Serum levels of IL-12 and TNF-alpha were detected by enzyme-labeled immunosorbent assay (ELISA) before and after treatment.

RESULTS(1) The total effective rate of the NG group, the combined treatment group, and the Tiapride group was 79.3%, 83.3%, and 67.9%, respectively. It was the lowest in the Tiapride group (P < 0.05). It was significantly higher in the combined treatment group than in the NG group (P < 0.05). (2) The post-treatment YGTSS score was obviously lower in each group after treatment than before treatment (P < 0.05). The posttreatment YGTSS score was obviously lower in the NG group and the combined treatment group than in the Tiapride group (P < 0.05), but with no statistical difference between the fromer two groups (P > 0.05).(3) Compared with the healthy control group before treatment, serum levels of IL-12 and TNF-alpha (pg/mL) were 124.95 +/- 22.78 and 209.52 +/- 21.69 in the NG group, 126.14 +/- 25.65 and 208.97 +/- 22.46 in the combined treatment group, 123.00 +/- 24.26 and 205.10 +/- 26.16 in the Tiapride group, being higher than those in the healthy control group (64.56 +/- 27.59 and 78.13 +/- 33.42; P < 0.05). After treatment, serum levels of of IL-12 and TNF-alpha were 104.67 +/- 16.84 and 183.01 +/- 24.95 in the NG group, 109.04 +/- 16.81 and 179.87 +/- 23.45 in the combined treatment group, significantly lower than before treatment (P < 0.05). But there was no statistical difference in serum levels of IL-12 or TNF-alpha in the Tiapride group between before treatment (123.00 +/- 24.26 and 205.10 +/- 26.16) and after treatment (117.75 +/- 16.79 and 199.76 +/- 33.21; P > 0.05).

CONCLUSIONNG could modulate abnormal serum levels of IL-12 and TNF-alpha in TS children patients, which might be one of its pharmacodynamic mechanisms for treating TS.

Objective To analyze the characteristics of iatrogenic urerteral injury and summarize the experiences in prevention,diagnosis and treatment of iatrogenic urerteral injury. MethodsA review was made on the injurycauses,the injury locations,the treatment time,the methods of surgical procedures and the results of treatment in 17 patients with iatrogenic ureteral injury treated surgically from 1997 to 2003. Results Of 17 cases of iatrogenic ureteral injuries,gynecological,general surgical and urological procedures resulted in ureteral injuries in 12 cases (71%),four (24%) and one (6%),respectively. Of all the injuries,65% (11/17) appeared in the lower part of the ureter,18% (3/17) in the middle part of the ureter and 18% (3/17) in the upper part of the ureter. The main injury causes were ligation,partial ligation,complete transection and perforation,accounting for 29% (5/17),41% (7/17),24% (4/17) and 6% (1/17),respectively. Four cases were found during operation,nine at days 2-11 after operation and four were treated 3-6 months after injury. Treatment methods included end-to-end ureteral anastomosis in seven cases,ureteroneocystostomy in three,ureteral lithotomy in one,pure ureteral lysis in three and post-lysis double-J tube insertion in three. All patients were cured. The follow-up ranging from six months to three years showed no patients suffering from urinary tract infection,hydronephrosis or atrophy. Conclusions The location and type of injury determine the type of surgical repair. A thorough knowledge of pelvic anatomy and mastering the basic steps of diagnosis and treatment are critical for prevention and management of the iatrogenic urerteral injury.

Estrogen receptors (ERs) are members of nuclear receptors and related to several diseases such as cancer, inflammation and osteoporosis. ERs have two forms, ERα and ERβ, which have different functions and organism distributions. Compounds selectively targeting ERβ can regulate important physiological functions and avoid the side effects caused by targeting ERα. Therefore, selective ERβ ligands have received considerable research interest in recent years. In this article, different kinds of selective ERβ ligands were summarized and their structure-activity relationships were also analyzed.
