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.

Although premature ejaculation (PE) is a common type of male sexual dysfunction, to date we lack a unified definition of PE. The multidimensional definition of PE has been accepted by more and more clinicians. Intravaginal ejaculatory latency time (IELT) is one of the three important dimensions (time to ejaculation, inability to control or delay ejaculation, and negative consequences) for defining PE. Rapid ejaculation is one of the core symptoms of PE and IELT is an objective measurement as well as an important tool for the evaluation of PE. This article reviews estimated IELT, stopwatch-measured IELT, the correlation between estimated and stopwatch-measured IELT, and the factors affecting IELT in the general male population, PE patients, and those complaining of PE.

Alternaria zinniae was a plant fungal pathogen isolated from a world-wide weed Xanthium occidentale,which could cause some weeds of Asteraceae disease. It was found that the fungus made disease spot on the leaf through producing secondary metabolite—phytotoxin. The toxin-producing capability of the fungus was studied. The optimal cultural conditions for producing phytotoxin were temperature 25℃,pH 6.5,cultured period 9~11d,rotating speed 110r/min,darkness and enough dissolved O_2,crude toxin was obtained through large scale fermentation. Analysis on the influence of time,temperature,lightness for storing on the stability of phytotoxin of Alternaria zinniae showed that the phytotoxin had the potential to develop as a herbicide originating from microorganism.

Objective To evaluate the effect of transcatheter closure of perimembranous ventricular septal defect (PMVSD) with symmetric ventricular septal occluder (SVSO). Methods Sixty-three patients with UCG confirmed PMVSD underwent transcatheter closure with SVSO. Results The implantation was successful in 58 patients (93.0%). The mean PMVSD diameter was 5.1?1.9 mm by angiography. The distance from the aortic valve to the rim of PMVSD was 2.7?1.0 mm and the mean size of SVSO was 7.2?2.1 mm. There was no residual shunt in 55 patients (94.8%) right after the deployment of SVSO. Arrhythmia was recorded in 15 patients (23.8%) during or after the procedure. New aortic regurgitation was observed in one patient after the implantation SVSO. Two patients developed myocardium injury and one patient developed obstruction of right ventricular outflow tract. Dislocation of the device was found in one patient. During the follow-up of 3 to 12 (means 7.4?2.7) months, no residual shunt, displacement or rupture of divices and endocarditis happened. Conclusion Transcatheter closure of PMVSD using SVSO is safe and effective, meanwhite attention should be paid to the complications such as arrhythmias.

Fibroblast growth factor 23 (FGF23) is a new endocrine factor, mainly expressed in osteoblasts and osteoblasts. Many studies have found that FGF23 can act on kidney, parathyroid and other tissues after binding with Klotho protein, and participate in bone mineral metabolism. In addition, in recent years, the role of FGF23 in exoskeleton has been gradually discovered, such as FGF23 and thyroid diseases, diabetes and so on. Therefore, understanding the biological characteristics, regulatory mechanism of FGF23 and its relationship with related diseases is of great clinical significance for the diagnosis and treatment of diseases. This article reviews the relationship between FGF23 and metabolic diseases such as phosphorus metabolic disease, parathyroid disease, hyperthyroidism, osteoporosis, diabetes, iron metabolism and so on.

Objective To explore the relationship between severity of symptom and immune function in left-to-right shunt congenital heart disease (CHD) infants combined with pneumonia. Methods The clinical data of 45 left-to-right shunt CHD combined with pneumonia infants were retrospectively analyzed. The infants were divided into 2 groups according to the modified Ross score:mild group (0-6 scores, 28 cases) and severe group (7-12 scores, 17 cases);then, the infants were divided into 2 groups according to deformities:single deformity group (the infants had a kind of deformity such as ventricular septal defect, atrial septal defect and patent ductus arteriosus, 21 cases) and composite/complex deformity group (the infants combined 2 or more deformities or other malformations, 24 cases). Twelve cases of healthy check-up infants were selected as control group. The levels of lymphocyte subsets (including CD3+, CD4+, CD8+, CD4+/CD8+, NK cell and B lymphocyte) and IgG, IgA, IgM were detected in every group. Results There were no statistical differences in IgG, IgA, IgM, CD8 +, CD4 +/CD8 +, NK cell and B lymphocyte among mild group, severe group and control group or single deformity group, composite/ complex deformity group and control groups (P>0.05). The CD3+ in severe group was significantly lower than that in mild group and control group (0.59 ± 0.10 vs. 0.69 ± 0.13 and 0.69 ± 0.12), the CD4+was significantly lower than that in control group (0.34 ± 0.07 vs. 0.45 ± 0.09), and there were statistical differences (P<0.05). For CD4+, though there was statistically difference among single deformity group, composite/complex deformity group and control groups (P<0.05), no statistically significant difference was in multiple comparison among the 3 groups (P>0.05). The CD4 + in the composite/ complex deformity group was significantly lower than that in the single deformity group and the control group (0.34 ± 0.07 vs. 0.45 ± 0.15 and 0.45 ± 0.09), and there was statistical difference (P<0.05). Conclusions In left-to-right shunt CHD infants combined with pneumonia, the reduction of CD3+and CD4+may be one of the causes of serious illness.
