Contrast agent was injected through the hand vein at 1.5 ml/kg, with pressure of 300 Pa, flow rate 2.5 ml/s. Before injection, we must complete the first scanning .Then , another 2 or 3 scans were done. Results:188 cases can show abdominal aorta, hepatic artery, splenic artery, hilar vessel branches, portal vein, inferior vena cava very well. Another two cases failed .The others were not ideal because of portal hypertension. Conclusion:CT enhancing scan based on bolus tracking technique in the upper abdomen can obtain good images to meet clinical needs.

Objective To investigate the relevant factors on the prognosis of sudden deafness. Method The clinical data of 133 patients (148 ears) with sudden deafness were analyzed retrospectively. Results Through systemic treatment, 25 cases got recovery, 18 cases were excellence and 39 cases were effective, the total effective rate was 61.7%(82/133). Univariate analysis showed that the factors related to the prognosis of sudden deafness were age, the time from onset to treatment, deafness classification,accompanied by vertigo or not and the duration of treatment. Patients with the age lower than 60, the earlier the time from onset to treatment, the lighter the deafness classification, not accompanied by vertigo and the longer duration of treatment got a better efficacy. Logistic regression analysis showed that the independent factors related to the prognosis of sudden deafness were the time from onset to treatment and deafness classification. Conclusion The etiology of sudden deafness is still unclear, the time from onset to treatment interval and the degree of hearing loss are the main factors affecting the prognosis of it, in clinic, it should be paid attention and took a early diagnosis and early treated so as to get good efficacy.

BACKGROUND:Extracorporeal cardiac shock wave therapy (CSWT) can up-regulate angiogenic factors and its receptors,promote angiogenesis and collateral circulation establishment by introducing shock waves to myocardium,however,the specific mechanisms remain unclearly.OBJECTIVE:To observe the influence of CSWT on the content of serum endothelial nitric oxide synthase (eNOS) in pigs following acute myocardial infarction (AMI).METHODS:Pig AMI model was established by embolizing the distal of left anterior coronary artery.Following model preparation,pigs were randomly divided into 2 groups.In the experimental group received three CSWT at days 1,3 and 5,200 hits per point,totally 12 points,with 0.09 mJ/mm~2 energy.Pigs with simple AMI were served as the control group.The serum eNOS level was detected by ELISA method before,immediate postoperative,and at days,1,3,5,and weeks 1,2,3,and 4 after operation.RESULTS AND CONCLUSION:The eNOS level of both groups were obvious decreased at immediate postoperative than that before operation.At day 1 after CSWT,eNOS level was increased in the experimental group,which was still decreased in the control group.It revealed that CSWT play a positive effect on ischemia rnyocardium.The eNOS level reached a peak in the experimental group after 3 times of CSWT,lasted for 2-3 weeks,and began to decrease at week 4.The difference between the experimental group and control group had significance (P＜0.01).The results demonstrated that CSWT can treat AMI effectively by promoting eNOS expression.

BACKGROUND: Coronary occlusion and balloon occlusion are two major methods in preparing acute myocardium infarction models. The pigs were expensive and the modeis will periorm further study,therefore,it is necessary to prepave a model with advantage of short time consuming, few trauma, and high survival rate.OBJECTIVE: To establish acute myocardium infarction in miniature pigs induced by coronary occlusion and balloon occlusion,and to compare the differences.DESIGN, TIME AND SETTING: The randomized grouping, contrast observation animal experiment was performed at the heart intervention room of The First Affiliated Hospital of Kun Ming Medical College between May 8~(th) and August 3~(rd), 2009.MATERIALS: A total of 20 Banna miniature pigs, weighing 20-30 kg, irrespective of genders, were purchased from animal department of Kunming Medical College. The animals were equally divided into embolism and occlusion groups.METHODS: In the embolism group, the balloon was implanted into distal end of anterior descending coronary via femoral artery,blocked the forward flow with 202.65 kPa pressure for 1, 2, and 5 minutes, with 60 seconds interval. The same operation was performed in the occlusion group, followed by blocked the forward flow for successive 60 minutes.MAIN OUTCOME MEASURES: Differences of modes established by 2 methods were compared by coronary opacification, ECG,myocardium zymogram, ultrasonic cardiogram and pathology detection.RESULTS: Nine pigs were survived in the embolism group, and the remained 1 pig died of coronary artery rupture. After operation, T wave inversion could be found, without ST stage raise. At day 1 after operation, correlated lead ST stage was raised 0.1-0.2 mV. The operation duration was 11 hours. In the occlusion group, 5 pigs survived, 4 pigs died of ventricular fibrillation,and 1 died without definite cause. The operation cost 24 hours, and the correlated lead ST stage was increased 0.2-0.3 mV postoperatively. Motion abnormality in infarction place was exhibited in both groups; ventricular aneurysm was formed in 3 pigs in the embolism group, and 1 in the occlusion group. Levels of creatine kinase isoenzymes serum troponin T were obviously stepped up and presented dynamic changes. The myocardiolysis was obviously showed in the infarcted areas, but the differences were no obviously in 2 groups.CONCLUSION: Both coronary occlusion and balloon occlusion can induce models of acute myocardium infarction. The coronary occlusion method is superior to balloon occlusion with few trauma, faster postoperative recover and low mortality rates.

Objective To compare the clinical efficacy and onset time between Tiao Ren An Shen (regulating Conception Vessel and soothing mind) needling method and conventional acupoint selection for peri-menopausal depression, for providing theoretical evidence for the application of Tiao Ren An Shen needling method. Method Sixty patients with peri-menopausal depression aged 45~55 years were randomized into two groups after admission to hospital. In addition to oral administration of Fluoxetine, one group was intervened by Tiao Ren An Shen needling method (treatment group, n=30), and the other group was by conventional acuppoint selection (control group, n=30). Before treatment, and at 2nd, 4th, and 6th week after treatment, Hamilton Depression Scale (HAMD) was investigated, Kupperman index and traditional Chinese medicine (TCM) syndrome score were evaluated before and after intervention. The therapeutic efficacy was estimated at the end of the 6th week. Result After intervention, the HAMD and TCM syndrome score were significantly improved in both groups (P<0.05); Kupperman score was markedly improved in the treatment group (P<0.05), while the score was not significantly changed in the control group (P>0.05). Compared to the control group, the improvements of depression degree and peri-menopausal symptoms were more significant in the treatment group (P<0.05). The total effective rate was 93.3% in the treatment group versus 70.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Compared to conventional acupoint selection, Tiao Ren An Shen method can produce a more efficient effect and a higher long-term efficacy, not only improving the emotional state and easing depression, but also releasing vegetative nerve functional disturbance. As it can improve the TCM symptoms, treating both causes and manifestations, promoting the quality of life of peri-menopausal patients, this method is an effective approach.

Objective To investigate the reason of fracture internal fixation of locking plates and conventional plate in the treatment of femoral fractures.Methods A total of 198 patients with femoral fracture taken plate fixation were selected as our subjects.Of which,the locking plate were used in 87 cases served as control group and 111 cases had traditional plate fixation served as study group.Fracture fixation rate in patients were follow-up and the reasons for broken were analyzed.Results Fracture fixation occurred 5 cases (4.5％,5/111) in the locking plate,and 3 cases (3.4％,3/87) in traditional plate,and the difference was not significant (x2 =0.053,P =0.987).Fracture reason included plate fracture (4 cases),fracture of screws (2 cases) and plate fracture complicated with breakage of screw (2 cases).Iatrogenic factors lead fracture fixation was 30.0％ (3/10),significantly higher in patients with rehabilitation exercises errors (6.9％,2/29; x2 =3.851 ; P =0.046).Both iatrogenic factors and rehabilitation exercises errors caused fracture fixation rate was 100％.Conclusion Iatrogenic factors combined rehabilitation exercises error was the main reasons in fracture fixation.We should properly choose fixation methods and correctly guide the postoperative functional exercise for patients.
