Objective To compare the effective difference of the flying needle with intradermal needle among the shu-acupoint group , the estazolam group and the non- point acupuncture group. Methods Three undred and fifteen patients who met the inclusion criteria were randomly enrolled into three groups for the insomnia severity index (ISI) and rating changes detection. After 2-week treatment,the patients were followed up at 4 weeks later. Results The ISI decreased gradually at 1 week, 2 weeks, and 4 weeks after treatment.The therapeutic effects of the three groups were all better than ever before at 1 week, 2 weeks, and 4 weeks after treatment (P<0.05). The follow-up therapeutic effect of the flying needle acupuncture group was better than that of the estazolam group and of the non-point acupuncture group (P<0.05). The curative effect of flying needle acupuncture is better than that in the other two groups (P < 0.05). Conclusion The subjective sleep quality of insomnia patients received flying needle with intradermal needle in shu-acupoint is beter than that of insomnia patients of the Estazolam group and of the non-point acupuncture group.

Purpose: To observe the clinical efficacy eye acupuncture in the control of acute attack of deficiency-syndrome asthma in china alone. Method: Random cross-comparison grouping was used to observe the curative effects in eye acupuncture, body acupuncture and medication groups. Results and conclusion: Both clinical control rate and marked effective rate in the eye acupuncture were higher than those in the body acupuncture group (P＜ 0.01),but not significantly different from those in the medication group (P＞ 0.05); plasma cAMP content and cAMP/cGMP ratio rose and plasma cGMP content dropped in the patients after the treatment, indicating that eye acupuncture, like body acupuncture and medication, can increase sympathetic excitability and stimulate adrenocortical functions to remove bronchial spasm.

PurposeTo observe the effects of blocking the renin-Angiotensin-Aldosterone system at different sites in experimental congestive heart failure (CHF)rats. Methods Six weeks after coronary ligation, rats( n = 66)were randomized to benalapril, losartan, spironolactone, placebo, and treated for 6 weeks. Sham-operated rats( n = 18) served as controls. Six weeks later left ventricular hemodynamics were measured. Results In the hemodynamic variables, HR was not significantly different between groups. Compared four treatment groups with sham-operated group, LVEDP increased, LVPSP and ± dp/dtmax decreased (P＜0.05). Compared with placebo group,all data in spironolactone group were not significantly different, LVEDP, mortality in benalapril group and in losartan group decreased, LVPSP and ± dp/dtmax in benalapril group and in losartan group increased(P ＜ 0.05). ConclusionsAdministration of ACEI and Ag Ⅱ-AT1 antagonist are effective in preventing from cardiac function deterioration, while spironolactone treatments are not. Spironolactone has tendency in decreasing LVEDP.

Objective To investigate the clinical and CT manifestations of iatrogenic hepatic subcapsular biloma (HSB).Methods Seven cases with iatrogenic HSB confirmed by paracentesis in our hospital,and 18 reported in literatures were enrolled into this study.Their clinical and CT manifestations were retrospectively analyzed.Results Of the 25 cases,9 were secondary to laparoscopic cholecystectomy (LC),5 were secondary to percutaneous transhepatic choleductus drainage (PTCD),4 were secondary to percutaneous transhe-patic removal of bile duct stones,2 were secondary to open cholecystectomy,and 5 were secondary to other surgeries.CT showed localized or diffused hepatic subcapsular fluid collection with crescent-shaped or sac-shaped.The hepatic volume decreased and the surface was compressed in some of the cases with diffused fluid collection.Conclusion When localized or diffused hepatic subcapsular fluid collection was detected in CT imaging after liver or gallbladder surgeries (especially LC and PTCD),HSB should be considered.Paracentesis should be performed as soon as possible.

Objective To observe the pathological changes of heart failure caused by transverse aortic constriction in rats.Methods Partial thoracotomy was performed to the second rib and the transverse aortic constriction was performed between the innominate and left carotid arteries to establish a model of heart failure in 24 rats.The same operation was performed on another 8 rats, except for the ligation of the transverse aorta.Echocardiographic assessment, hemodynamic measurement, myocardial histopathological examination and NT-proBNP measurement were performed to the sham group at 12 weeks and model group at 4 weeks, 8 weeks, 12 weeks after the operation.Result At 4 weeks after the operation, NT-proBNP, EF, FS and -dp/dtmax of the model group was significantly increased and LVESV, +dp/dtmax of the model group were significantly decreased (P<0.05).At 8 weeks after the operation, EF and-dp/dtmax of the model group were increased and +dp/dtmax of the model group was significantly decreased (P<0.05).At 12 weeks after the operation, NT-proBNP, EF and +dp/dtmax of the model group were decreased, and LVESV, LVEDV and -dp/dtmax of the model group were increased (P<0.05).The cardiomyocytes became hypertrophic and lined up in disorder at 4 weeks after the operation.Pathologic examination of the myocardial tissue showed connective tissue proliferation and inflammatory cell infiltration at 8 weeks after the operation, and cardiomyocyte apoptosis and collagen fiber deposition at 12 weeks after the operation.Conclusions Transverse aortic constriction induces heart failure in rats.The pathological processes are compensatory hypertrophy at 4 weeks after the operation, initial reaction of decompensation at 8 weeks after the operation, and heart failure at 12 weeks after the operation.
