adult female Wistar rats undergone bilateral adrenelectomy were diveded to four groups:(A)simple bilateral adrenalectomy;(B)bilateral adrenalectomy with pieces of adrenal glands alloimplanted to the subrenal capsule (SRC);(C)the same with group B followed by institution of cyclosporing A(CsA) from the operative day to the 14th postoperative day;(D) group C plus ACTH given from 3rd to 31st postoperative day. Five months follow-up showed that all the grafts survived, regenerated and the serum corticosteron levels were in correspondence with histological features. This result showed SRC is an ideal site for adreal homotransplantation. Varying degrees of lymphocytyc infiltration were present in the implants in group B on the 2nd to 21st postoperative day, the fragment in groun C and D in which CsA was given did not show any lymphocytic infiltration, even after CsA was discussed. ACTH instituted in group D remarkably enhances the regenerative speed of the grafts After CsA and ACTH were stopped, no rejection episode appeared and the adrenal grafts survived well. The result has been similar to clinical homotransplantation of adrenal glands with vasculas anastomosis.The technigue is simple and the adrenal gland used for homotransplantation is easy to obtain.

Objective To observe the effectiveness and safety of clopidogrel combined with fibrinolytic therapy for acute ST segment elevation myocardial infarction(STEMI).Methods From January 2004 to December 2006,a total of 158 STEMI patients in our hospital were treated with fibrinolytic agents combined with or without clopidogrel.There were 84 patients in clopidogrel group,including 66(78.6%)male,18(21.4%)female and 45(53.6%)elderly patients(aged ≥ 60 years);74 patients were in control group,including 58(78.4%)male,16 female(21.6%)and 40(54.1%)elderly patients.Clinical characteristics,patency of infarct-related artery(IRA),30 d major adverse cardiac events(MACE),recurrent angina and hemorrhage events of the two groups were retrospectively analyzed.Efficacy and safety of fibrinolytic therapy combined with clopidogrel in elderly patients(≥60 years old)subgroup were also estimated.Results Baseline clinical characteristics between the two groups were comparable.Clopidogrel therapy was associated with a higher proportion of patent IRA(69.1% vs 51.4%,P=0.035)and lower rates of cardiac death(0 vs 6.8%,P=0.047)and MACE(2.4% vs 12.2%,P=0.036).There was no significant difference in the incidence of recurrent angina(3.6% vs 2.7%,P=0.885),slight and severe hemorrhage events(7.1% vs 9.5%,P=0.811;1.2% vs 1.4%,P=0.533)between the two groups.In elderly patients,clopidogrel therapy was associated with a higher proportion of patent IRA(68.9% vs 45.0%,P=0.045),the declining tendency in MACE(2.2% vs 12.5%,P=0.155),but no significant differences in the other indexes.There were no significant differences in above-mentioned indexes between the elderly and younger patients in clopidogrel group.Conclusion Addition of clopidogrel to fibrinolytic therapy is safe and effective for both the elderly and younger STEMI patients.

Objective To study the feasibility and clinical effect of trans umbilical single incision laparoscopic right hemicolectomy for right hemicolon carcinoma.Methods The clinical data of 35 patients with right hemicolon carcinoma were retrospectively analyzed,the 15 cases were received the trans umbilical single incision laparoscopic right hemicolectomy (single incision group) and 20 cases were received laparotomy right hemicolectomy (laparotomy group).The clinical indexes were compared between the 2 groups.Results The length of incision,intraoperative bleeding volume,passage of gas by anus time,feeding time,hospitalized time in single incision group were significantly better than those in laparotomy group [(5.5 ± 0.6) cm vs.(17.6 ± 2.2) cm,(84.0 ± 31.1) ml vs.(155.5 ± 43.1) ml,(2.00 ± 0.76) d vs.(3.75 ± 0.63) d,(5.3 ± 0.6) d vs.(6.5 ± 0.6) d,(9.3 ± 1.4) d vs.(13.5 ± 1.5) d],the operation time in single incision group was significantly longer than that in laparotomy group [(238.4 ± 19.3) min vs.(165.3 ± 25.8) min],there were statistical differences (P ＜ 0.05).There was no statistical difference in number of incision lymph node between the 2 groups (P ＞ 0.05).Postoperative complication in single incision group occurred in 2 cases,postoperative complication in laparotomy group occurred in 3 cases,there was no statistical difference (P ＞0.05).The follow-up time was 1-55 months,the median follow-up time was 28 months,local recurrence and distant metastasis were found in 2 cases in single incision group,and 4 cases was found in laparotomy group,there was no statistical difference (P ＞ 0.05).Conclusions Single incision laparoscopic right hemicolectomy for right hemicolon carcinoma is safe and feasible,which has the advantages of minimal trauma,aesthetic outlook,less bleeding,quick recovery and short hospitalization time,etc.It can be developed in the hospital which has some basis of laparoscopic surgery.

Objective To report single-center experience on CBA combined with LAAC in treat-ment of AF.Methods A retrospective study was conducted on 27 AF patients undergoing one-stop surgery of CBA combined with LAAC in Department of Cardiovascular Diseases of the People's Hospital of Liaoning Provincie from August 2020 to November 2022.The efficacy and safety of the surgery were analyzed.Results There were 22 patients(81.5％)with LAmbre and 5 patients with Watchman(18.5％,including one case of 24 mm Watchman FLX).All the patients achieved complete pulmonary vein isolation,and conversion to sinus rhythm during operation.During a mean follow-up of 30.0±9.2 months,24 patients(88.9％)maintained sinus rhythm at 12-month follow-up,and 22 patients(81.5％)maintained sinus rhythm at 24-month follow-up.TEE at 3 months after operation displayed that all the devices were in good positions and no PDL or DRT was observed.In the 11 patients undergoing cardiac enhanced CT in 12-36 months after surgery,PDL was detected in one patient(9.1％),and uncomplete endothelialisation of the device was observed in another one(9.1％)using the Watchman device.TEE at 26 months revealed one patient(3.7％)of DRT.Conclusion One-stop surgery of CBA combined with LAAC is a feasible treatment option for patients with NVAF and at high risk of stroke.
