Objective: To establish the model of inbred strain rat heart heterotopic transplantation.Methods:Male Lewis rats were used as recipients and Brown-Norway rats as donors,and the heterotopic transplants were done using ono's method with some modifications.The ascending aorta and pulmonary artery of donor were anastomosed end-to-side to the recipient abdominal aorta and inferior vena cava respectively.Results:48 heart transplantations were performed.We summarized surgical technique after sixteen rats of preliminary experiment.The successful rate was improved to 96.88% in 32 rats of formal transplantation.Time of cold ischemia,hot ischemia and rebeat were shorten significantly and operational time reduced to 60 min.Conclusion:To strengthen the protection of donor heart and perioperative treatment is the key point in the heart heterotopic transplantation in inbred strain rat.

Single incision laparoscopic surgery (SILS) has many advantages than standard multiport laparoscopic cholecystectomy (MLC),such as small trauma,less postoperative pain,shorter hospital stay,good cosmetic effect,and so on.Especially the satisfying cosmetic result of no abdominal scar is more important.But the SILS is also faced with many difficulties.The operation time of SILS were significantly longer in duration than MLC.The safety and the technical feasibility were lower for the SILS whose operation complications are more than the MLC.The main reason is that the operation field don't exposureis sufficient and the formation of surgical operation triangle is not easy.In order to overcome these difficulties,scholars have used the auxiliary methods of exposing the operative field in various operation,including the penetration of abdomen wall retraction and intraperitonealretractionand abdomen wall retraction.This paper with review the advantages and disadvantages of the above methods aiming to affer more values for clinical doctors in opperating SILS who get more knonledge abont it.

Objective To study the efficacy of complement depletion with CVF in preventing a-cute rejection after heart allotransplantation in inbred strain rats. Methods Inbred male Lewis rats were used as recipients and Brown-Norway rats as donors, and the heterotopic heart transplantation model was established. The allografts were divided into 2 groups (n=8 in each group). After infusing low-dose CVF 20?g/kg to the CVF-treated group, cardiac allograft survival time was observed on 4 rats of each group. The remaining 4 rats in each group were killed respectively at day 1,3,5 and 6, the pathological grade for acute rejection, the complement activity in serum, the deposition of C3 on tissue, and the extent of infiltration by CD3+ T cells were compared. Results The mean survival time of heart allograft was (11. 69?0. 72) days and (6. 65?0. 35) days in CVF-treated group and control group respectively (P

Objective:To establish a quality control standard for psoraleae fructus tinctures. Methods:The identification was de-tected by TLC on silica gel G plates with hexane-ethyl acetate (8∶2) as the developing solvent. An HPLC method was applied in the quantitative determination of psoralen and isopsoralen as the effective components. The analytical column was Intersil ODS-3 (250 mm × 4. 6 mm,5 μm) with methanol-water(45∶55) as the mobile phase;the flow rate was 1 ml·min-1;the detection wavelength was at 246 nm and the column temperature was set at 35℃. Results:The characteristic spots for psoralen and isopsoralen were identified by TLC. The concentration of psoralen showed good linearity within the range of 4. 88-187. 50μg·ml-1(r=0. 999 9)and the average re-covery was 102. 63% and RSD was 0. 43%. The concentration of isopsoralen showed good linearity within the range of 4. 25-163. 20μg ·ml-1(r=0. 999 9), and the average recovery was 102. 37% and RSD was 1. 13%. Conclusion: The qualitative and quantitative methods are simple, accurate, feasible and repeatable, which can be used in the quality control of psoraleae fructus tinctures.

Objective To investigate the effect of exercise preconditioning on the expression of nerve growth factor(NGF) and its receptor TrkA as well as learning-and-memory abilities in rats suffered from focal cerebral ischemia.Methods Thirty-six male SD rats were randomly divided into sham operation group (Sham-MCAO,n=12),focal cerebral ischemia-reperfusion group (MCAO,n=12) and exercise preconditioning + cerebral ischemia-reperfusion group (EX+MCAO,n=12).Rats in EX+MCAO group were placed in the treadmill device and accepted 4 weeks exercise training.Then method of middle cerebral artery occlusion was applied to prepare transient focal cerebral ischemia reperfusion model.Garcia's method was used to assess the neural function in rats.Western blotting was applied to test the expression of NGF and TrkA protein in the successfully established experimental MCAO rats.Morris water maze experiment was uti lized to test the learning-and-memory abilities of the rats.Results (1) Compared with Sham-MCAO group,the expression of NGF in rats' brain tissue was lower in MCAO group (cerebral ischemia 1h reperfusion 24h) (P＜0.05).The expression of NGF of EX+MCAO group was higher than that of MCAO group,but still lower than that of Sham-MCAO group (P＜0.05).(2)The expression of TrkA in rats' brain tissue was higher in MCAO group compared with Sham-MCAO group (P＜0.05).Compared with MCAO group,the expression of TrkA was even higher in EX+MCAO group (P＜0.05).(3)On the fifth day in the Morris water maze test,the latency of MCAO group was significantly longer than that of Sham-MCAO group((9.36± 1.18)s vs (4.86± 1.52) s,P＜0.05).However,compared with MCAO group,the latency in EX+MCAO group ((6.02± 1.04) s) was shorter,but still longer than Sham-MCAO group (P＜0.05).There was no significant difference among the three groups in the average swimming speed (P＞0.05).Conclusion Exercise preconditioning can up-regulate the expressions of NGF and TrkA protein,which can also improve the learning-and-memory abilities in rats suffered from focal cerebral ischemia reperfusion injury.

Radiation therapy is one of the important comprehensive treatment strategies for thoracic neoplasms,but it also can cause radiation-induced heart disease (RIHD) which can affect the quality of life and even endanger the lives of patients while killing tumor.With the development of comprehensive treatment for cancer,the patients achieve better survival outcomes.And the study reported about RIHD increased as well,which made RIHD became an important complication of thoracic neoplasms' treatment.Though modem radiotherapy techniques and new therapeutic principles have significantly made the incidence of RIHD decreased,the harm of RIHD should not be ignored.In this article,we review the research progress of RIHD.
