Double aortic arch is a congenital heart defects,which is related to vascular rings.It accounts for about 0.5％ of the incidence of congenital heart disease and will result in varying degrees of airway compression of the esophagus,such as wheezing breathing,swallowing difficulties,severe respiratory distress or chronic respiratory symptoms.Spiral CT,echocardiography and cardiovascular imaging can diagnose double aortic arch.Double aortic arch is divided into three types,the treatment of which is different and surgery is effective.In recent years,with the improvement of thoracoscopic technique,thoracoscopic surgery has become an effective means of treatment to double aortic arch.This review focuses on the surgical treatment of double aortic arch progress.

A 21 years old male patient was admitted with a complex trauma of metal penetrating wound in maxillo facial region,neck and chest because of a high falling accident one hour ago. General examination:the vital signs were stable. Specialized examination: metal foreign body penetrated from the front wall of the axilla ,passing left clavicle superficies, through the middle of neck into the posterior pharyngeal wall, then piercing out from the superciliary arch lateral. The patient had apparent tenderness in the right arch,right zygomatic bone and the front of right maxilla. the degree of mouth was about 1. 8cm. X-ray showed the foreign body: from left armpit to right temporal part. The admission diagnosis was : 1. metal penetrating wound in maxillo-facial,neck and chest; 2. right zygomatic maxillary and zygomatic arch fractures. Treatment: the foreign body was removed smoothly through the concurrent operation, and by scendary operation of open reduction and internal fixation of fractures, the finally result of patient was good.

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.

BACKGROUND:There are abundant cel populations in the placenta that attracts more and more attentions because of high content of CD34+cel s. It is expected to become a new source of hematopoietic stem cel s for the treatment of hematologic diseases and other malignant diseases.
OBJECTIVE:To investigate the amount of cel s derived from placenta, their colony forming ability, and their chimerism analysis.
METHODS:Five placentas obtained from five healthy ful-term cesarean women were treated with perfusion method and tissue digestion for the cel col ection. Flow cytometry was used to detect the proportion of CD34+cel s in the placenta and cord blood, fol owed by the culture of cel colonies as wel as regular observation of cel morphology and counting. PCR amplification with sequence-specific primers and sequence-specific oligonucleotide probes were used to examine HLA type of placenta, umbilical cord blood, and maternal peripheral blood;Short tandem repeat PCR was used for chimerism analysis.
RESULTS AND CONCLUSION:There were more CD34+cel s in the placenta than in the umbilical cord blood. The placenta had good ability to form multiple colonies in vitro, and there were maternal source components in the placenta. It is concluded that the amount of cel s in the placenta and their biological functions exhibit the potential use of placenta as a new source of hematopoietic stem cel s.

Objective To investigate the effect of state anxiety and trait anxiety on attentional orienting of heroin addicts. Methods State anxiety and trait anxiety was measured by State-Trait Anxiety Inventory (STAI). Forty heroin ad?dicts (36 males and 4 females) and 40 healthy controls (36 males and 4 females) participated in cue-target task. Atten?tional orienting and reorienting were measured in valid cue trials and invalid cue trails. Results Heroin addicts had sig?nificantly greater state anxiety [(42.65 ± 6.58) vs. (36.60 ± 8.91)] and trait anxiety [(44.43 ± 7.67) vs. (37.00 ± 8.63)] values than controls (P<0.05). The state anxiety was significantly correlated with orientation RT difference (r=-0.259, P=0.020) and disengaging/reorientation RT difference (r=0.333, P=0.003) in heroin addicts. Trait anxiety was also significantly cor?related with orientation RT difference (r=-0.248, P=0.026) and disengaging/reorientation RT difference (r=0.356, P=0.001) in heroin addicts. Conclusion Heroin addicts have significantly greater anxiety than healthy controls. Both their state anxiety and trait anxiety are associated with attentional orienting and disengaging/reorienting.

OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).

METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.

RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.

CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.

Fosfomycin (FOM) is an antibiotic with a small relative molecular weight (138.1) and a long half-life, and has a unique chemical structure and antibacterial mechanisms. It exerts a bactericidal activity by inhibiting the early synthesis of bacterial cell walls. It is also a broad-spectrum antibiotic with a good drug tolerance and compliance and a low pressure to bacterial resistance, but no cross-resistance with other antibiotics. Recent studies show the effectiveness of FOM in the treatment of acute uncomplicated urinary tract infections and urogenital tract infections as well, such as prostatitis and epididymitis. This review focuses on the clinical application of FOM in the treatment of infectious diseases of the urogenital tract.
