In-stent restenosis after interventional treatment remains an unsolved and important clinical problem. The proliferation and migration of arterial smooth muscle cells are key events frequently followed by vascular restenosis after angioplasty and continuous inflammation may also be the other important factor for the restenosis after stenting. Study of the pathogenesis of restenosis may find some potentially novel therapeutic pathways for attenuating in-stent restenosis.

The international meeting of the 10th anniversary of the AADO, convoked from Oct.8 to Oct. 10 in 2002 in Shanghai, was sponsored by AADO and organized by the two orthopedics departments of Changhai Hospital and Ruijin Hospital, Shanghai. The supporters of this meeting were Stryker Pacific, Stryker Trauma and Stryker China. There were 180 conventioneers who came from all over the mainland China, America, Germany, India, Japan, Hong Kong and Taiwan. They were clinical specialists in traumatology, managers from traffic departments and experts in vehicle design. 17 theses were selected for the meeting. The theme of the meeting was musculoskeletal trauma in developing countries with focus on road traffic injuries &geriatric fall injuries. Many experts in orthopedic trauma were invited to give presentations at the meeting on the theme.

Objective To evaluate the diagnosing and typing value of ultrasonography in adult congenital ureter cysts.Methods Ultrasonography findings were depicted of 29 cases with adult congenital ureter cysts confirmed by surgical and pathological examinations. Results In 29 cases of congenital ureter cyst, 14 occurred in right lateral, 12 in left lateral, and 3 in bilateral, totally being 32 cysts. The largest size of the cyst in diameter was (5.2) cm, and the smallest was (0.4) cm. Twenty-eight cases was diagnosed correctly by ultrasonography,in which the accuracy was (96.6)%(28/29). According to the sonographic patterns of size, shape, periodical change,1 case hydronephrosis, surgical and pathological results, 32 adult ureter cysts were divided into four types: type Ⅰ, papillary(12); type Ⅱ, round or ellipse(9);type Ⅲ, semilunar(4);and type Ⅳ, oblate(7). Conclusions Ultrasonographic appearance of adult ureter cyst is specific, and ultrasonography is of great value.

Objective To investigate the effect of goserelin combined with marvelon in treatment of en -dometriosis(EM)and its effect on estrogen levels .Methods 120 EM patients were randomly divided into the ob-servation group(60 cases)and the control group(60 cases)according to the digital table.Two groups underwent laparoscopy .3.6 mg sustained release goserelin was injected subcutaneously from the anterior abdominal wall once every four weeks on the first time of menses recovery .The treatment continued during the following six months.The observation group were treated with marvelon on the basis of this , 1 tablet each day, 21 days of con-tinuous treatment and then began to take medicine on the 5 th day of the next menstruation during the following six months.The two groups were followed up for two years .The level of luteinizing hormone(LH), follicle-stimula-ting hormone(FSH)and estradiol(E2), the cumulative pregnancy rate, recurrence rate and peri menopausal sta-tus of the two groups were observed before and after treatment .Results The total effective rate was 96.67%and 83.33%respectively for the observation group and the control group .The difference had statistical significance (P<0.05).The level of E2, FSH, and LH at 1 month, 3 months, 6 months after treatmnet was lower than that before treatment(P<0.05).The level of E2, FSH, LH of two groups had no statistical difference (P<0.05). The cumulative pregnancy rate of the observation group was higher than that of the control group while the recur -rence rate was lower than that of the control group ( P<0.05 ) .The perimenopausal symptom score ( Kupperman score)of the two groups had no significant difference (P>0.05).Conclusion Goserelin combined with marvel-on can effectively improve the effect of laparoscopic surgery in treatment of endometriosis , lower estrogen level , improve patients'pregnancy rate , and reduce the recurrence rate .

Objective To explore the effect of cilazapril on motor and cognitive function in hypertension with brain stroke. Method 42 hypertensive patients with stroke were divided into cilazapril treatment group(22 cases) and traditi onal treatment group (20 cases). The cilazapril group was treated with Inhibace 2.5 mg～5 mg daily. The traditional group was treated with nifedipine and/or di uretic. The blood pressure was measured twice a day during the treatment course. The activity of daily living (ADL), motor and cognitive function were assessed with Barthel index, Fugl-Meyer and MMSE assessment respectively before and 6 we eks after treatment. Results There were no difference between the two groups on blood pressure effectiveness, but blood pressure was more stable in the cilazapril gro up. Improvement of ADL and lower limb motor function in cilazapril treatment gro up were improved significantly than those of traditional treatment group(P<0.05). Although there was no difference between the two groups in the total value of cognitive function assessment, but the directional ability and memory function in group wa s higher than those in traditional group (P<0.05). Conclusion Cilazapril can decrease blood pressure steadily and can improve the activity of daily living and cognitive function in stroke patients.

AIM: To investigate the change of estrogen receptor (ER) in hippocampus, hypothalamus and pituitary of female rats exposed to psychological stress, and to illuminate the mechanism of dysfunction on ovarian reproductive endocrine function. METHODS: Sound, light and electricity were combined into a psychological stressful stimulus to induce female rat dysfunction on ovarian reproductive endocrine function. Immunohistochemical technique and image analysis were used to assess the expression levels of ER in hippocampus, hypothalamus and pituitary. RESULTS: When exposed to compound stressful stimulus of sound, light and electricity for 20 days in female rats, the expression levels of ER in hippocampus, hypothalamus and pituitary dropped. CONCLUSION: The decrease in estrogen receptor expression in hippocampus, hypothalamus and pituitary of female rats exposed to psychological stress may be one of the mechanisms of ovarian reproductive endocrine dysfunction.

[Objective]To investigate the causes and treatment methods of postoperative complications of femoral fractures treated with interlocking intramedullary nails.[Method]A total of 243 cases of femoral fractures from Jan 1999 to Dec 2004 were treated with interlocking intramedullary nails.There were 14 cases having complications,delayed union in 1,nonunion in 3,nailing failure in 6(locking scerw loosen in 4,locking scerw folding in 1,locking scerw breakage in 2),nail breakage in 1,re-fracture in 1 and knee ankylosis in 1.Two cases with delayed union to convert the fixation from statictody namicin time;3 cases with nonunion were treated with bone grafting.Breakage nail and re-fractuer cases were treated with enlarging intramedullary tunels,exchanging nails and bone grafting.One of locking scerw loosen were treated with exchanging nails and bone grafting.Knee ankylosis were treated with quadriceps plasty.[Result]Through treatment,the delayed union and the nonunion were all healed and got recovery of knee function.[Conclusion]Though it has certain complications,the interlocking intramedullary nails used for femoral fractures have more advantages than other internal fixations.It needs to take valid measures to reach a satisfying result when complication appears.

[Objective]To compare the value of the MR imaging and arthroscopy for detecting articular cartilage erosion,and to evaluate the clinical effect of MR imaging on the correct diagnosis in the early stage of articular cartilage lesion.[Method]Twenty-six patients(27 knees)with persistent knee pain who were scheduled for arthroscopy underwent MR scanning,including 3D FS-FSPGR,FSE PDWI and FSE T1WI sequences.The results of each sequence were then compared with the arthroscopic findings.[Result]Using arthroscopic results as the standard of reference,the 3D FS-FSPGR images had the higher sensitivity(96.5%)and accuracy(95.0%)than the standard MR imaging,the 3D FS-FSPGR sequence was well consistent with the result of arthroscopic,Kappa value was higher(0.776)than the other sequences(P
