1.Study on pathogenesis for in-stent restenosis
Journal of Interventional Radiology 2006;0(10):-
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.

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 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.

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 investigate the expression of E-cadherin(E-cad)and the relationship with the Lauren classification,the degree of histological differentiation,the clinical stage,the depth of invasion,lymph node metastasis and distant metastasis of gastric cancer. Methods 80 cases architecture of gastric cancer and normal tissue were collected.The expression level of E-cad in 80 cases of gastric carcinomas and their metastatic lymph node tissues were examined by immunohistochemical assays.Results The expression rate of E-cad in 80 cases of gastric carcinomas Was 55.00%.The expression level of E-cad was positively correlated with the Lauren classification,the degree of histological differentiation,the clinical stage,the depth of invasion,lymph node metastasis and distant metastasis(P<0.05),but Was not correlated to patients sex,age and tumor size.The expression rates of E-cad in metastatic gastric carcinoma of primary lesions and lymph nodes metastasis were 35.48%and 32.26%. respectively. Furthermore, E-cad expression in metastatic gastric carcinoma was significandy correlated with primary lesions and lymph node memstasis(r=0.4978,P<0.05).Conclusion The expression level of E-cad in gastric carcinoma Was closely correlated with the degree of tumor differentiation,infiltration and transferring.

The radioactive iodine uptake(RAIU) has great value in determining the 131I treatment dosage of patients suffered from hyperthyroidism and judging thyroid function. Many factors which could interfere the results of RAIU were as follows: instrumental factors, thyroid radioactivity counts measurement, counts of a calibrated standard in a neck phantom and counts of room background, iodinated drugs and food, anti-thyroid medication, among other causes, have shown to induce varying degrees of errors in RAIU measurements. Irregular measurements which may interfere with radioactive iodine uptake are commonly seen in clinical practice, yet its actual influence has not been reported. Optimization, regularization and quality control of the radioiodine uptake measurement are essentials for clinical routine practice to guarantee appropriate values for clinical hyperthyroidism diagnosis and treatment. All the above factors affecting the measurement of thyroid function instrument for radioactive iodine uptake are analyzed and then put forward the corresponding solutions.
