Objective To investigate the effects of moldavica total flavone on vascular endothelial growth factor (VEGF), intercellular adhesion molecule-1 (ICAM-1), nitric oxide (NO) and endothelin-1 (ET-1) in ovalbumin-induced bronchial asthmatic rats, and explore its mechanism. Methods A total of 60 SD rats was randomly divided into control group, model group, dexamethasone (1 mg/kg) group and moldavica total flavone low (90 mg/kg), medium (180 mg/kg) and high (360 mg/kg) dose group. Rats asthma model was established by ovalbumin challenge methods except the control group. After modeling, rats in control and model groups were intragastrically given distilled water, rats in medicine groups were intragastrically given moldavica total flavone and dexamethasone for 30 d. VEGF in lung tissue and ICAM-1 in bronchoalveolar lavage fluid (BALF) were detected respectively by ELISA. The content of ET-1 and NO in BALF were analyzed with radioimmunity method and nitric acid reductase method. Results The VEGF in lung tissue and ICAM-1, NO and ET-1 in BALF were decreased by moldavica total flavone at 180 and 360 mg/kg (P<0.05, P<0.01) in ovalbumin-induced bronchial asthmatic rats. Conclusion Moldavica total flavone is effective in adjusting abnormal increase of VEGF, ICAM-1, ET-1 and NO of bronchial asthma rats.

Objective To evaluate the application of tubular stomach gastroesophagostomy on the life quality after esophagectomy surgery.Methods From March 2011 to September 2011,66 cases of esophageal cancer patients were divided in two groups in randomized principles.Tirty-four cases in group of tubiform gastro surgery whose the stomach was cut into tubiform stomach in width of 4 cm.And 32 cases of conventional group and whose surgery method was adopted to maintain whole stomach but cut the cardia.And then,using statistical methods,life quality after esophagectomy (treatment related symptoms,general symptoms,daily life,social life,emotional activities) and the perioperative complications were evaluated in 3,6,12,24 months in comparison and analysis.Results Sixty-six surgeries of both group patients were successfully performed,tumor resection rate was 100％,and there was no intraoperative accident also no perioperative death.There was no statistical significance of perioperative complications of 2 groups (P ＞ 0.05).Life quality of tubiform gastro group had improved apparently more than conventional group at the 3rd,6th,12th and 24th month after surgery(78.68 ±2.23 vs 65.94± 4.13,83.79 ± 2.40 vs 66.84 ± 5.86,86.41 ± 1.94 vs 67.09 ± 4.43,89.02 ± 1.71 vs 68.88 ±3.53,P＜0.05).At each time point,there were statistically significant differences between tubiform gastro group and conventional group on treatment related symptoms,general symptoms,daily life,emotion activities (P ＜0.05).At the 3rd,6th month after surgery,tubiform gastro group and the conventional group had no statistically significant difference in the aspect of social life (P＞0.05).In the conventional group,the evaluation of quality of life at each time point after surgery and before a point in time in the same group showed no statistical significance (P＞0.05).Conclusion Tubiform gastro esophagectomy has a positive influence on life quality of patients of esophageal cancer after surgery prospectively.

Objective To investigate the effect of moldavica total flavone on pulmonary function and collagen type Ⅲ in lung tissue of ovalbumin-induced bronchial asthmatic rats. Methods A total of 60 SD rats were randomly divided into control group, model group, dexamethasone group, and moldavica total flavone low, medium and high dose group. Rat asthma model was established by ovalbumin challenge methods except the control group. The control and model group were intragastrically given distilled water, medicine groups were intragastrically given moldavica total flavone and dexamethasone for 30 d, once per day. After the last administration, the pulmonary function and airway responsiveness including breathing frequency (F), minute ventilation (MVb), peak inspiratory flow (PIFb), peak expiratory flow (PEFb) and enhanced pause (Penh) were measured by using non-invasive measurement system (Penh system, Buxco, USA). The collagen type Ⅲ in lung tissue were detected by ELISA. Results The moldavica total flavone at 180 and 360 mg/kg decreased F and Penh (P<0.05, P<0.01), increased MVb, PIFb and PEFb (P<0.05), and decreased collagen type Ⅲ in lung tissue (P<0.05, P<0.01). Conclusion Moldavica total flavone can relieve the airway hyperresponsiveness and remodeling, improve respiratory function of ovalbumin-induced bronchial asthmatic rats.

OBJECTIVE: To assess the efficacy and adverse reaction of nasal packing materials Rapid Rhino and Merocel. METHOD: We searched the database PubMed, EMBASE, Cochrane Library, CBM, CNKI, VIP and WANFANG database on line by computer, and traced the related references. Randomized controlled trials(RCTs) of rapid rhino and merocel as nasal packing materials were included. The quality of the included documents was evaluated by the criterion of Cochrane handbook 5.1. The cochrane collaboration's Revman 5.1 software was used for data analysis. RESULT: Four RCTs involving 115 patients were identified. Meta-analyses showed that Rapid Rhino produced significantly lower pain and discomfort during insert of pack [MD = 1.37, 95% CI (0.13, 2.60), P < 0.05], whereas less pain and discomfort during removal of pack [MD = 2.88, 95% CI (2.34, 3.41), P < 0.01]. Rapid Rhino associated with a significantly slighter degree of fullness raised after insertion [MD = 1.15, 95% CI (0.75, 1.55), P < 0.01, and the same situation happened after 6 hours [MD = 1.15, 95% CI (0.75, 1.55), P < 0.01]. Rapid rhino caused to less reactionary bleeding when pack removal [MD = 0.26, 95% CI (0.12, 0.39), P < 0.01], rapid rhino was easier for the healthcare worker during insert and removal. There was no significant difference between two packs on the efficiency of hemostatic [OR = 1.00, 95% CI (0.38, 2.61), P > 0.05]. CONCLUSION The application of Rapid Rhino caused less pain and fullness, leaded to slighter bleed than Merocel when insertion and removal. There was no significant difference between two packs on the efficiency of hemostatic when used for epistaxis or after routine nasal surgery.

Objective The aim of our study was to establish an endoscopic endonasal transsphenoidal surgical training model, and to examine its application value. Methods The endoscopic endonasal transsphenoidal surgical training models were made.After assessments,the models was used for endoscopic operation training for 8 neurosurgeons with no experiences of endoscopic operation. Results The available operating space of this model is similar to the actual operating space in endoscopic endonasal transsphenoidal surgery. The egg fixed on the model has many layers of structure, such as eggshell, shell membrane, egg white and egg yolk, which constituted a good practice object. All students indicated that they could benefit from the training using this model. The skill in grinding the eggshell [(1.07 ± 0.221)cm2/min vs.(1.45±0.27)cm2/min, P<0.001]was significantly improved and the chance for shell membrane rupture (8 vs. 2, P=0.007) was significantly reduced in the last-time practice compared with the first-time practice (P<0.001). Conclusion The endoscopic endonasal transsphenoidal surgical training model is helpful for neurosurgeons to practice the basic operation of endoscopic surgery and to improve their surgical skills,and can be used repeatedly.It can be used in basic operation training before the training using cadaver cranium.
