Objective To design an experimental model of endoleak after endovascular exclusion(EVE). Methods Infrarenal aortic aneurysms were created with bovine jugular vein segements or patches. Then they were undergone endovascular stent graft exclusion of the aneurysm. Using modification of prosthetic vessel and changing the attachment site, endoleaks were formed druing the course of aneurysm exclusion. Results All the 6 aneurysms possessed satisfactory configuration just as clinical patterns. Intraoperative arteriography revealed endoleaks in 5 dogs after the exclusion, two of which were proximal and three were distal.Conclusions This experiment shows the hemodynamics and treatment of endoleak for EVE.

Premature ejaculation (PE) is a common male sexual disorder with an incidence rate of 20-30%. Recent clinical trials have demonstrated that phosphodiesterase type 5 inhibitors (PDE5i), as the first-line drug for erectile dysfunction (ED), can improve ejaculatory function probably by acting on the peripheral and central adrenergic nerves. The possible action mechanisms of PDE5i may involve lessening of the central sympathetic output, modulation of the contractile responses from the vas deferens, seminal vesicles, prostate and urethra, induction of peripheral analgesia, and prolonging of the total erectile duration, increasing the confidence of ejaculation control, and reducing the post-ejaculation refractory time. This review discusses the possible mechanisms and clinical application of PDE5i in the treatment of PE.

miRNAs were discovered less than a decade ago, and have emerged as important regulators of gene expression in mammals. A large number of miRNAs have been identified to be located within the intronic regions of protein-encoding genes(host genes) and called intronic miRNAs. The intronic miRNAs may play a key role in regulating the expression and function of their host genes due to the fact that most of them are co-expressed with the host genes. In this paper, the recent advances on the research on potential relationship between intronic miRNAs and their host genes are reviewed.

Chitinases genes from Metarhizium anisopliae which is an important entomopathogenic fungus were considered one of the key factors to invade their hosts. One Metarhizium anisopliae HN1 strain was isolated and screened. A chitinase gene was amplified by RT-PCR from Metarhizium anisopliae HN1, The whole length of this gene was 1275bp,and the nucleotide sequence of the gene was 96% similarity to that of the M. anisopliae E6 accessed in GenBank ( AF02749). The gene has been registered in GenBank and its accession number is DQ011865. The gene was subcloned into prokaryon expression vector pET-22b( + ), transformed this recombinant expression plasmid into E. coli strain BL 21 and effective expressed. The SDS-PAGE analysis indicated that the recombinant protein was 42kDa which is same to the reported article. The expression level of recombinant protein was about 63. 3% of whole expressed proteins , And when recombinant E. coli were crushed by freeze and supersonic wave , the activity assay indicates that the chitinase expressed in bacteria possesses biological activity.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.
METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.
RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.
CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

Objective To investigate the association of angiotensinogen(AGT)gene A-6G、T174M and G-217A polymorphisms with the risk of essential hypertension(EH)in the elderly of Han nationality.Methods Genotypes of AGT gene A-6G,T174M and G-217A polymorphisms in 177 aged EH patients and 86 sex and age-matched controls were analyzed with gene chip technology.Results The A-6G and T174M polymorphisms of AGT gene were significantly associated with EH.The numbers of the three genotypes of A-6G were 113,58 and 6 in the patient group and 70,15 and 1 in the control group(P= 0.014)and those of T174M were 94,77 and 6,60,25 and 1(P=0.031),respectively.G-217A polymorphism was not related to EH.Individuals carrying A-6G AA and T174M CC genotypes showed 57% and 56% lower risk of EH(OR=0.43;95%CI=0.23-0.82 and OR=0.44;95%CI=0.25-0.79, respectively).Conclusions The A-6G AA and the T174M CC genotype may be related with decreased risk of EH and G-217A polymorphism may have little role in the etiology of EH in Han nationality.

OBJECTIVETo investigate clinical outcomes of tendon allograft reconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury.
METHODSForty-eight patients with knee dislocation were reconstructed anterior and posterior ligament under arthroscopy at stage I from January 2008 to January 2012, and repaired ligaments injury of knee joint by minimally invasive technique. There were 38 males and 10 females aged from 20 to 59 years old with an average of 35.6 years old; 22 cases on the left side and 26 cases on the right side; the time from injury to operation ranged from 2 d to 2 weeks. Two cases combined with anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL) and posterolateral complex injuries, 36 cases combined with ACL, PCL, and MCL injuries, 10 cases combined with ACL, PCL and PLC injuries; 4 cases combined with peroneal nerve injury. Lysholm scoring were used to compared the cases before operation and final following-up to evaluate knee function.
RESULTSAll patients were followed up from 12 to 30 months with an average of (18.2 ± 6.3) months. Activity and stability of joint were obviously improved. Lysholm score were improved from 40.3 ± 4.1 before operation to 87.0 ± 6.4 at final following-up.
CONCLUSIONReconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury could recover stability of joint better,reserve joint function. Preoperative training and postoperative individualized rehabilitation treatment is the key point of recover knee joint function.
