Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.

Objective To study the mechanism of oxidative stress involved in the pathogenesis and relapse of acute monocytic leukemia (M5 ).Methods We detected reactive oxide species (ROS)levels,conducted plasma analysis obtained from 76 M5 patients at diagnosis and at relapse,and observed the ultrastructure of mitochondria of mononuclear cells in peripheral blood by transmission electron microscope.Results Compared with that in the control group,the average fluorescence intensity of intracellular ROS was significantly increased in M5 groups, especially in the relapse patients (P < 0.05 ).Low total antioxidative capacity (T-AOC)and antioxidant enzyme activity were characteristic of M5 at both diagnosis and relapse. However, lactate dehydrogenase (LDH ), malondialdehyde (MDA)and 8-hydroxy-2’-deoxyguanine (8-OHdG)increased significantly at both diagnosis and relapse (P < 0.05 ).Prominent ultrastructural abnormalities (mitochondrial swelling,outer membrane blebs,and aberrant cristae disorder)were present in patients with primary M5,and they were obviously abnormal in relapsing M5 patients.Conclusion Oxidative stress is the initiating factor of M5.Mitochondria are the main intracellular location for ROS generation.To maintain the dynamic balance between ROS and antioxidant defence may be the critical factor for preventing relapse.

Objective To introduce and evaluate a new surgical technique about concealed penis.Methods The incision was chosen on the outer lamina of the bilateral sides of penis.The excision of fibrous cord of penis dartos and suprapubic fat pad and skin fixation on the penis root were done to the patients.For the severe patients,the superficial layer of the suspensory ligament of penis must be excised.Thirty-nine cases were treated with this new technique,22 cases with Devine technique,and 23 cases with modified Shiraki technique and clinical comparative research was carried out.Results Penis of 39 cases were found 2 to 3 centimeters pro-pubic projection.Within 3 to 36 months of follow-up,no obvious reduction of penis was found and the erection function was normal.By new evaluat standard of surgical efficacy,the clinical efficacy of new technique,Devine′s and modified Shiraki′s technique were 92.31%(36/39 cases),77.27%(17/22 cases) and 78.26%(18/23 cases),respectively and the efficacy rate in new technigue was significcmthy higher than that of Devines and modified Shirak′s groups(Pa

OBJECTIVETo study pharmacokinetic effect of Aikeqing Granule (AG) by different medication ways on zidovudine (AZT) in highly active antiretroviral therapy ( HAART) of rats.

METHODSTotally 36 rats were administered with corresponding medications by gastrogavage, group I [HAART: AZT 31.5 mg/kg +3TC 31.5 mg/kg + Efavirenz (EFV) 63.0 mg/kg], group II (HAART+AG525 mg/kg), group III (HAART and AG 525 mg/kg after a 2-h interval). Drug concentrations of AZT were determined by high performance liquid chromatography-mass spectroscopy (HPLC-MS) before HAART, and at 0.5, 1, 2, 3, 4, 6, 8, 10, 12 h after HAART, respectively. Pharmacokinetic parameters [such as t1/2, Tmax, Cmax, AUCo-t, plasma clearance rate (CL)] were calculated by DAS2.0 Software.

RESULTSThe-equation of linear regression of AZT was good, with the precision, coefficient of recovery, and stability definitely confirmed. AUC in group II and III was larger than that of group I. There was no statistical difference in t1/2, Tmax, Cmax, AUC0-12 h, or AUC0-∞ among groups (P > 0.05).

CONCLUSIONAG combined HAART could enhance the Cmax of AZT.

This study was aimed to explore if the intracellular transportation direction of von Willebrand factor-cleaving protease (ADAMTS13, vWF-CP) after synthesis is determined by the carboxyl terminal TSP2-8CUB1+2 domains of ADAMTS13 and to decipher the relationship between the structure and function of ADAMTS13. The recombinant plasmids pcDNA3.1-ADAMTS13 and pcDNA3.1-delTSP2-8CUB1+2 ADAMTS13 were introduced into Madin-Darby canine kidney cells (MDCK) by lipofectamine-mediated DNA transfection. Positive cell clones gained after antibiotic-screening were grown on 6-well transwell filter units with a zeolite membrane in the middle layer. The conditioned culture media in both apical and basolateral wells were collected when cells reached confluency and the tight cell monolayer formed. ADAMTS13 proteases in the conditioned media were determined by Western blot, and the direction of ADAMTS13 secretion in polarized cells was comparatively analyzed. The results showed that Madin-Darby canine kidney cells stably expressing wild-type ADAMTS13 were grown on 6-well transwell filter units, then ADAMTS13 protease was only determined in the apical area of the transwell filter units by Western blot, but the recombinant ADAMTS13 protease was determined both in the apical and basolateral area of cells in the group of expressing TSP2-8CUB-1+2 domain-deleted ADAMTS13. It is concluded that the metalloprotease ADAMTS13 is sorted apically in polarized cells, and the carboxyl-terminal TSP2-8 and CUB1+2 domains of ADAMTS13 are important for the direction of ADAMTS13 protease transportation in the cells after being synthesized.

AIMTo manage male infertility with obstructive azoospermia by means of percutaneous epididymal sperm aspiration (PESA) and intrauterine insemination (IUI).

METHODSNinety azoospermic patients with congenital bilateral absence of the vas deferens (BAVD, n=58) or bilateral caudal epididymal obstruction (BCEO, n=32) requesting for fine needle aspiration (FNA), PESA and IUI were recruited. The obstruction was diagnosed by vasography and determination of the fructose, carnitine and alpha-glucosidase levels in the seminal fluid.

RESULTSThe mean sperm motility, density, abnormal sperm and total sperm count of the caput epdidymis were 16 %+/-22 %, (12+/-31) x 10(6)/mL, 55 %+/-36 % and (16+/-14) x 10(6), respectively. In the 90 couples, a total of 74 PESA procedures and 66 cycles of IUI were performed. Three pregnancies resulted, including one twin pregnancy giving birth to two healthy boys, one single pregnancy with a healthy girl and another single pregnancy aborted at week 6 of conception. The pregnancy rate per IUI cycle was 4.5 %.

CONCLUSIONThe birth of normal, healthy infants by IUI using PESA indicates that the caput epididymal sperm possess fertilization capacity. The PESA-IUI programme is a practical and economical procedure for the management of patients with obstructive azoospermia.
