Objective To investigate the value of MRI in thmmbolytic thempy of hyperacute cerebral arterial thrombosis.Methods One hundred and sixteen patients with acute cerebral arterial thrombosis were recruited.plain CT and multi.modal MRI were performed in all patients.Thirty-three patients with hyperacute cerebral infarction were treated bv recombinant tissue plasminogen activator(rt-PA) and followed-up periodically using MRI.Results The 33 patients with thrombolysis selected by MRI demonstrated clinical improvement.90 d moclified Rankin scale scores(mRs)were less than 2 and life quality Barthal indexes(BI)were from 80 to 100.The complication included one asymptomatic parenchymal hematoma(PH1)one weeks after thrombolytic therapy and 4(12.2%)hemorrhagic infarction(HI)6 to 24 hours after thrombolytic therapy.Condusions MRI has significant clinical value for the screening and follow-up of intravenous thrombolytic therapy of hyperacute ischemic stroke.MRI-based thrombolysis is a safe and effective method for hyperacute ischemic stroke.

Objective To explore the application of Lux1540 nm non-stripping array laser in fa-cial rejuvenation .Methods A total of 100 patients were collected for Lux1540 nm non stripped lattice laser treatment in patients with facial skin aging ,once a month ,totally four times treatment ;1 month after the treatment ,the skin of patients was analyzed by skin image analyzer VISIA for quantitative e-valuation .Results After 4 treatments ,the skin wrinkles ,texture ,pores ,skin roughness ,brown spots ,erythrocyte and purple spots were all improved ,with statistically significant differences (P <0 .05) ,while the changes of ultraviolet spots were not obvious ,and the differences were not statistical-ly significant (P > 0 .05) .After treatment ,80 patients were satisfied ,17 were comparatively satisfied , and 3 were dissatisfied ,with a satisfactory rate of 97％ .All patients had needle-like pain during the treatment ,which could be tolerated without local anesthesia ointment .Ice compress was given after treatment ,which significantly alleviated the discomfort after treatment .Only 3 cases had mild pig-mentation .During the treatment and follow-up ,no adverse events such as skin redness and swelling , pigmentation and pruritus were found .Conclusions Lux1540 nm non-ablative dot array laser has posi-tive efficacy ,high safety and few side effects in facial rejuvenation ,and it is an effective method to treat facial skin aging .

The embryonic leaflets of peanut (Arachis hypogaea) variety Huayu 20 were used as explants and pingyangmycin as a mutagen to induce somatic embryos. Four weeks after the inoculation, the survived explants were transferred to somatic embryo germination medium containing screening reagent hydroxyproline, and finally 15 regenerated plants were obtained. Pedigree breeding method was used during the following selection breeding, and three lines with significantly increased yield and 23 lines with high oil content were obtained from these mutant offsprings. The line with both high yield and high oil content has passed peanut variety multi-location in Anhui province and was named "Yuhua 4". Its yield was 16.63% higher than that of the control variety Baisha 1016, ranking the first in all the testing varieties. Yuhua 4 showed the characteristics of early maturity, small pod and high oil content. The oil content of kernels was 56.10%, higher than that of original parent Huayu 20 with 49.50% oil content, tested by the Ministry of Agriculture of Oil and Products Quality Supervision, Inspection and Test Center (Wuhan), and the yield was 15% higher than that of Huayu 20. It was concluded that in vitro mutagenesis and target screening was an effective way on creating new germplasm and breeding new variety in peanut.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
