Objective　To evaluate the treatment of in-stent restenosis with rotational atherectomy and balloon angioplasty. Methods　The rotational atherectomy and 4～6 atm low pressure balloon angioplasty was performed in 3 patients with in-stent restenosis and follow up after treatment. Results　All cases were succeeded. The bradycardia occurred in one patient was quickly disappeared without treatment, two other patients were found no effect on heart rate, hemodynamic performance, global LV function, or regional wall motion. No complications, angina, death or other coronary event occurred during the follow up for 6～12 months. Two of them was performed coronary angiography after 6 months and showed the diameter of target vessel was less than 30% as compared with that on coronary angiography which performed immedately after operation. Conclusion　The management of in-stent restenosis in target vessels using a combination of rotational atherectomy and balloon angioplasty is safe and efficient.

Objective To investigate the relationshp among Gp Ⅱ b/ⅡⅢ a、CD62p in platelet activation mark-er and high-sensitivity C-reactive protein (hs-CRP) in elderly patients with chronic cor pulmonary exacerbation. Methods The subjects were divided into four groups (42 elderly patients with cor pulmonary exacerbation,42 eld-erly patients with cot pulmonary remission,30 cases of healthy elderly subjects and 30 cases of healthy non-elderly subjects) . The expression of Gp Ⅱ b/Ⅲ a and CD62p were measured with tricolor flow cytometry. Hs-CRP levels were measured by nephelometry and turbidimetry in patients and normal controls. Results Compared with cor pul-monary remission group,healthy elderly group and healthy non-elderly group, the levels of Gp Ⅱ b/Ⅲ a, CD62p and hs-CRP increased significantly in patients with chronic cor pulmonary exacerbation ( all P < 0.001 ). Gp Ⅱ b/Ⅲ a and CD62p results of the elderly patients with cot pulmonary remission were higher than those in healthy elderly subjects (P <0.05) and healthy non-elderly subjects (P < 0. 001 ) . The expressions of both Gp Ⅱ b/Ⅲa and CD62p in healthy elderly subjects were statistically higher than that in healthy non-elderly subjects ( P < 0.05 ). There was a positive con'elation between the Gp Ⅱ b/Ⅲ a、CD62p and hs-CRP in elderly patients with chronic cot pulmonary exac-erbation(r =0.59,P<0.01 ; r=0.54,P<0.01 ). Conclusions The platelet in elderly patients with chronic cot pulmonary exacerbation is overactivated,which is correlated with hs-CRP.

Objective This study was designed to evaluate the effect of laparoscopic-assisted subtotal colectomy(LASC)and modified Duhamel procedure in the treatment of severe functional constipation(SFC).Methods From June 2005 to October 2007,100 cases of SFC were treated by LASC combined with modified Duhamel procedure in our institute.After freed the colon under a laparoscope,we made a small incision in the lower abdomen to perform subtotal colectomy while preserved the ileocecal region.Then a side-to-side colorectal anastomosis was conducted.Results In this study,98 cases of LASC were successively completed and 2 cases were converted to open surgery.The operation time of LASC in the 98 cases ranged from 48 to 125 min mean,(76?23)min],and the total operation time was 140-225 min mean,(170?42)min].The intraoperative blood loss was 10-160 m1 mean,(35?18)m1].In the patients,the intestinal function was recovered within 25-52 hours mean,(42?12)h] after the operation;none of them developed postoperative wound infection,anastomotic stoma,or other complications.One week after the operation,2 of the 100 patients showed mild dehydration,and 2 were diagnosed as having incomplete small bowl obstruction.All of the four were cured by conservative treatments.The other 96 patients who had no complication were discharged from the hospital in 5-11 days mean,(7.0?1.5)days] postperation.One year later,the symptoms of constipation were significantly alleviated(defecation 1-3 times/d)in 90 patients;7 cases had various degrees of diarrhea(defecation 4-6 times/d);and 3 patients showed recurrence of mild constipation(defecation 1 time/2-3 d).The gastrointestinal quality of life index(GIQOL)determined in 1 year postperation was(109?20)points,which indicated good results compared to(94?23)points before the operation(maximum:144).Eighty-three cases were satisfied with their frequency of defecation.Conclusions LASC combined with modified Duhamel procedure is an effective method for the treatment of SFC,resulting in less damage,less influence to the internal environment,and quick recovery.The procedure is worth being wildly used.
