Objective To discuss the feasibility of the lung transplantation as an effective treatment for end-stage pulmonary diseases domestically and to compare the major issues involving the practice of lung transplantation domestically and overseas.Methods After the foundation of group of lung transplantation in May 2002, lung transplantation models of porcine were set up. From September 2002 to April 2005, in the 18 cases undergoing lung transplantation, there were subjected to single-lung transplantion (SLT, 83.3%) and 3 bilateral sequential single lung transplants without CPB (DSSLT, 16.7%). Indications for SLT (n=15) included emphysema (n=9), pulmonary fibrosis (n=3), pneumosilicosis (n=1), lymphangioleiomyomatosis (n=1) and ventricular septal defect (VSD) induced Eisenmenger's syndrome (n=1); for DSSLT (n=3) bronchiectasis (n=1) and pulmonary emphysema (n=2). Among the 15 SLTs, there were 9 cases of left SLT and 6 right SLT. Among them, 2 cases shared one same donor's lung block, one case received contralateral lung transplantation―a left donor lung implanted in the recipient’s right thorax, and one case simultaneous right SLT and VSD repair. Results In hospital mortality (HM) was 3/18 ( 16.7%). Among SLTs, early death was due to severe rejection on the 30th postoperative day in one patient and acute rejection on the 15th postoperative day in other patients, and another patient died due to pulmonary vein embolism on the 36th day. There were 3 and 2 patients with the survival time longer than 1 and 2 years respectively. The median overall survival was 10 (2 to 32) months. Conclusions Our LT program shows similar results to those reported by the International Society for Heart and Lung Transplantation for developed countries. The key of successful operation depends on the establishment of group of lung transplantation and cooperation of multi-department. Ischemic-reperfusion injury, acute-rejection and infection are the major reasons of deaths shortly after the operations.

Thirty cases of peripheral facial palsy were treated with the comprehensive therapy, and 30 cases of peripheral facial palsy were treated with shallow electro-acupuncture as control. The results showed that the cure rate in treatment group was higher than that in the control group(P＜ 0.05), and no significant difference was found in effective rate between two groups.

Objective To investigate the impact of pancreatic duct stenting as a preventive measure for post-ERCP pancreatitis in patients with repeatedly non-selective pancreatic duct cannulation.Methods Clinical data of 64 patients with biliary tract disease from January 2008 to December 2015 was prospective analyzed. All the patients were randomly divided into observation group and control group. Patients in observation group received pancreatic stent placement, while patients in control group was not received pancreatic stent placement and nasal duct. Postoperative monitoring items included abdominal pain, blood amylase. Then record and compare the incidence of acute pancreatitis, pancreatitis severity rating, abdominal pain score, Ranson score, amylase recovery time between the two groups.Results Observation group had ifve cases of PEP, the rate was 15.6 %, including mild four cases (12.5 %), medium one case (3.1 %); the control group had 13 cases of PEP, the rate was 40.6 %, including mild six cases (18.8 %), medium four cases (12.5 %), severe three cases (9.4 %). PEP observation group was signiifcantly lower than the control group (P < 0.05). Mild, medium and severe PEP were lower than the control group, in which the severe PEP was signiifcantly lower than the control group (P < 0.05). Ranson score of the observation group was (1.2 ± 0.4), significantly lower than the control group (2.5 ± 1.2) (P < 0.05); the observation group amylase average recovery time was (3.0 ± 0.6) d, it is also signiifcantly lower than the control group (5.8 ± 1.4) d (P < 0.01). No bleeding and perforation complications occurred.Conclusion Pancreatic stenting can effectively prevent the incidence of PEP, reduce postoperative pain, improve patient recovery.

Objective The decease of varicose vein and telangiectasis of lower extremity has always been difficult to treat.Regular treatments and medicines are invalid.This research aimed to study the effect of foam sclerotherapy and the long-pulsed 1064 nm Nd∶YAG laser in treatment of reticular veins and telangiectasis of lower extremity.Methods From January 2012 to June 2012,excluding deep and superficial veins valve insufficiency of the lower extremity through duplex uhrasonography,72 patients with simple reticular veins and telangiectasis of the lower extremity were treated with foam sclerosing agent injection combined with Nd∶YAG 1064 nm laser therapy.Results Of the 72 patients,cure was achieved in 38 cases,significantly effective in 32 cases,effective in 2 cases,and total effective rate was 100％.Follow-up showed that after 3 months 1 case was dissatisfied,3 cases were discontent,6 relatively satisfied,32 satisfied,and 30 very satisfied;after 12 months no cases were very dissatisfied,1 cases were discontent,9 relatively satisfied,28 satisfied,and 34 cases very satisfied.There were no severe complications in all cases.Conclusions Foam sclerotherapy and Nd:YAG 1064 nm laser can be used for different stages of the treatment process and different caliber of blood vessels.Treatment with foam sclerotherapy and Nd∶YAG 1064 nm laser for reticular veins and telangiectasia of lower extremity is a safe,simple and effective way.

Conclusions By adequate preparation for infants, effective immobilization and good cooperation of operators, and combined with techniques which prevent PICC misplacement, overcome the shortcoming of bad vessel and non-compliance of infant patients, develop the advantage of ultrasound, could improve the rate of successful catheterization of upper arm PICC insertion in infant patients, and protect the vessels.

BACKGROUND:Combining Chinese medicine with stem cel transplantation opens up a new avenue for the use oftraditional Chinese medicinein thestem cel transplantation. It is expected to improve survival and differentiationof cochlear stem celsintohair cels through Chinese medicine interventions.
OBJECTIVE:To observe the influenceofGuiqi Dihuang Tangon the treatment of sensorineural deafness with cochlear stem cels.
METHODS:Guinea pigs with sensorineural deafness were randomly assigned into three groups:combined group intervened with cochlear stem cel suspension with medicated serum, cel transplantation group with cochlear stem cel suspension, and blank control group with normal saline injection. At 7, 28 and 56 days after treatment, al guinea pigs were detected for auditory brainstem response and immunofluorescent observation.
RESULTS AND CONCLUSION:Nestin positive cels and MyosinVIIA positive cels were observed in the combined and cel transplantation groups, and the number of positive cels was higher in the combined group than the cel transplantation group. Auditory brainstem response threshold of guinea pigs was decreased in the combined and cel transplantation groups, and the recovery of hearing was better in the former group. These findings indicate that the intervention ofGuiqi Dihuang Tangcan remarkably improve the survival rate of transplanted stem cels and the differentiation ratioof transplanted celsintohair cels.

Objective To study the imaging features of the ventricular meningioma, in order to improve the understanding knowledge. Methods Compared with operative and pathological findings,the CT and MRI features of ventricular meningioma were analyzed in 22 patients (8 males and 14 females,range from 17~72 years old with average age 45 years).21 cases were examined by MRI(17 with enhanced scan),11 cases by CT(4 with enhanced scan).Results The ventricular meningioma were mostly fibrous type. Mostly, the locations were in the trigone of the lateral ventricle with regular shape. On imaging, the most were parenchymatous with markedly enhancement. Calcification may be found, but cystic changes and hemorrhage were very rare.Conclusion The ventricular meningiomas have characteristic imaging features. CT and MRI are valuable in diagnosis, especially MRI.

Objective To study the imaging features and the cause of the cystic meningiomas so as to avoid the misdiagnosis and improve the understanding and knowledge. Methods CT and MRI features in 27 pathologically proved cystic meningiomas were analyzed. There were 10 men and 17 women, and the age ranged from 16 to 80 years with the average age of 49 years. Twenty-six patients were examined by using MRI (24 with enhanced scan), and 15 patients by CT (seven with enhanced scan). 15 patients were examined by both CT and MRI. The image features were analyzed according to Nauta and were compared with operative and pathological findings. Results The cystic meningiomas were mostly epithelial type, but fibrous type, angiomatous type, or papillary type may also be seen. Mostly, the locations were cerebral convexity, but tumors of the tentorium, alisphenoid, olfactory groove, and skull base were also seen. And all were sessile. On imaging, most tumors were parenchymatous with cystic parts, and marked enhancement of the parenchymatous part could be seen. Some were entirely cystic with parenchymatous nodule, the nodule enhanced markedly and the wall of the cyst may be or not be enhanced. Of the 27 cases, four cases were NautaⅠ, seven cases were NautaⅡ, one case was Nauta Ⅲ, and ten cases were Nauta Ⅳ. Three were both Nauta Ⅱand Ⅲ in 3 cases, Nauta Ⅱ, Ⅲ, and Ⅳ in 1 and both Nauta Ⅲ and Ⅳ in 1, respectively. Conclusion The cystic meningiomas have characteristic imaging features. CT and MRI, especially MRI, are valuable in the diagnosis.
