ObjectiveTo investigate the pattern of the relationship of craniopharyngiomas with pituitary stalks and hypothalamus. Furthermore, based on different patterns affirmed during the operations, surgical strategies were designed for radical excision. MethodsA series of 66 patients with primary suprasellar craniopharyngiomas were treated with microsurgical techniques and the relationships of the craniopharyngiomas with pituitary stalk and hypothalamus were analyzed prospectively. Appropriate surgical approaches were selected preoperatively according to the lesion's sizes and expanding directions. The relationships of the lesions to the pituitary stalks and hypothalamus were identified in detail and dissected carefully with protection of perforating vessels. ResultsThe patterns that pituitary stalks were involved by craniopharyngiomas were identified in 36 cases and divided into four types: no relation (5 cases), adhesion (10 cases), partial invasion (8 cases) and total invasion (13 cases). The anterior floor of the third ventricle was involved in 42 cases, in which it disappeared totally in 10 cases. Total resection was achieved in 58 case, subtotal resection in 8 cases. Diabetes insipidus (DI) was identified in 44 cases postoperatively. No surgical mortality, no recurrence was found during follow-up of mean 35 months. ConclusionThe appropriate selection of surgical approaches preoperatively, careful identification and according treatment of the relationships of the tumors with pituitary stalks and hypothalamus are the keys to protect the pituitary stalk; hypothalamus in craniopharyngiomas resection in adults.

Objective To explore the effect of budesonide(BUD) on dendritic cell(DC) and airway inflammation in the asthmatic mice.Methods Forty female Kunming mice were divided into 4 groups:asthmatic model group,therapeutic control group,BUD treated group,and normal control group,with 10 mice in each group.Mice were sensitized by an intraperitoneal injection of 50 ?g ovalbumin(OVA) adsorbed to 1 mg aluminum hydroxide dissolved in 0.2 mL saline.Animals were boosted on the 14th day in the same way.From the 21th to 35th days,and mice were challenged with 10 g/L aerosolized OVA for 30 min a day to establish a murine model of asthma.To evaluate the effect of BUD,60 minutes prior to OVA exposure,the mice were treated with 1 mg aerosolized BUD or placebo(saline).Control animals were sensitized intraperitoneally with saline and challenged with aerosolized saline alone.Eosinophil(EOS) count,degree of mucus secretion and DC count around the airways were measured by haematoxylin and eosin staining,periodic acid schiff's staining,immunochemistry technique and computerized image analysis system.Results In asthmatic model group,EOS count,DC count and the degree of mucus secretion around the airways were increased compared with nomal control group(P_a0.05).In BUD treated group,EOS count,DC count and the degree of mucus secretion around the airways were decreased compared with the asthmatic model group(P_a

Although there is great technological disparity between the best foreign lithotripters and domestic ones, the clinical efficacy of the latter is quite good. In this article, the characteristics, developing status and clinical applications of domestic lithotripters are introduced.

Objective To investigate the operative method and clinical rusults of repairing and reconstruction for bone and skin defect at medial malleolus.Methods Form January,2013 to January,2015,11 cases of patients with malleolus complex tissue defect were treated.According to the degree of damage to the cases were divided into four types,according to the type,selected flap,blood vessels,nerves,tendon graft,flap series connection iliac bone flap graft to repair,or direct ankle fusion,amputation to therapy.The Iliac flap donor site remained part of the anterior superior iliac spine and rebuild muscle starting and ending point,the donor sites wound was closed by skin graft.Results Followed-up of 1-24 months,in addition to amputation and ankle fusion each one exception,the remaining 9 patients underwent ankle reconstruction to reserve ankle.One case acquired infection,other 8 patients healed well,had different degree of recovery of the ankle function,the ankle function had recovery in different degree.AOFAS ankle-hindfoot score system:excellent in 4 cases,good in 4 cases,and poor in 1 case.Conclusion Ankle complex tissue defect classification method can be used to guide us to select the treatment options.Iliac bone flap series consisting mainly of composite tissue transplantation is a viable method of the medial malleolus defect reconstruction.

Objective To dynamically observe the concentrations of plasma neuropeptide Y(NPY)in the patients with lower extremity arteriosclerosis obliterans(ASO)before and after vascular interventional therapy.Methods The levels of plasma NPY were detected by radioimmunoassay in 13 patients with lower extremity ASO(ASO group)before vascular intracavitary therapy and immediately,1 d,3 d and 5 d after vascular intracavitary therapy.Meanwhile,15 healthy subjects were served as control group.Besides,the ankle-brachial indexes(ABI)and clinical staging of ASO group were also obtained and compared before and 3 d after vascular intracavitary therapy.Results Compared with control group,the level of NPY in ASO group was much higher before vascular intracavitary therapy[(250.67?88.27)pg/mL vs(168.40?64.64)pg/mL,P
