Objective To investigate the clinical characteristics,manifestation and management of adrenal ganglioneuromas. Methods The data of 15 cases of ganglioneuromas diagnosed by pathology were reviewed retrospectively.Of the 15 cases,5 was male,aged 24 to 45 with an average of 29 years,and other 10 was female,aged 25 to 69 with an average of 31.Ten tumors were located in the right side,which was twice as many as that of the left side.There were 8 patients discovered by B ultrasonograpgy during health check-up,4 patients were detected because of paroxysmal abdominal pain. Three cases mainly presented with paroxysmally hypertension,and one of them had a high level of aldosterone ( 112 pmol/L). One of them had a high level of epinephrine (210 nmol) and nor-epinephrine (496 nmol). The B-ultrasound showed low-echo in all cases.Five cases showed calcification,the border was legible.The border lines of the tumors are not clear with vana cava in two cases. On unenhanced CT scanning,all cases showed low density areas.Eleven of the 15 cases underwent the enhanced CT,but 10 cases showed no enhanced areas on CT scanning.One case underwent MRI and showed low signals in T1 WI and inhomogeneous high signals in T2WI. Results Twelve cases underwent adrenal glands tumorectomy with abdominal NO.11 intercostals incision while other 3 underwent adrenal glands tumorectomy through posterior abdominal laparoscope.The tumors were completely removed in 14 cases,partly removed in 1 case.All patients recovered soon without complications such as bleeding or adrenal crisis.All cases were followed-up 13 to 74 months.The blood pressure of 3 cases with hypertension decreased to normal.The tumors recurred in 1 case,but no metastasis 55 months later. Conclusions It is difficult to differentiate adrenal medullary tumor from ganglioneuromas.The imaging data of iconography before surgery can give helpful information in the diagnosis of ganglioneuroma.Complete surgical excision is the only method for curing and the outcome is satisfactory.

Objetive To investigate the effect of Fasudil on the hepatic ischemia repeffusion injury on rats of obstructive jaundice.Methods 160 mature SD rats were randomly assigned into 2 large groups,namely experimental group (Group A) and control group (Group B).While each large group was subdivided into 4 subgroups,including sham operation subgroups(Group A1 and B1),obstructive jaundice model subgroups(Group A2 and B2),ischemia reperfusion model subgroups (Group A3 and B3)and obstructive jaundice plus ischemia reperfusion model subgroups (Group A4 and B4).In Group A2 and B2,obstructive jaundice models were made on rats by double ligating and cutting the common bile ducts.In Group A3 and B3,the ischemia reperfusion injury models were built by blocking the hepatic portal vessel for 30 minutes before reperfusion.In Group A4 and B4,the ischemia reperfusion injury models were built in 1 week after building the obstructive jaundice models.For Group A,10 mg/kg fasudil was intraperitoneally injected at 30 minutes before ischemia.For Group B,equal amount of physiological saline was injected.Samples were gained on zero hour,1 hour,2 hour and 6 hour post reperfusion.The serum indexes for liver function and serum Endothelin 1 level were tested and analyzed through SPSS.Pathological changes of liver were viewed correspondingly.Results Compared to control groups (Group Bs),experimental groups (Groups As) have better liver function,lower Endothelin 1 level (P ＜ 0.05),as well as less severe microscopic histological damage.Conclusion Fasudil can effectively protect rats of obstructive jaundice from hepatic ischemia reperfusion injury.

This study was to build a canine portal hypertension model by intra-portal administration of high polymer material polyurethane and organic solvent tetrahydrofuran mixed solutions in order to evaluate the effectiveness of the model. Twelve local crossbreed dogs were selected randomly, with intra-portal administration of 8% (weight/volume) polyurethane- tetrahydrofuran solutions through an incision in the upper abdomen to build the portal hypertension model. We measured the portal vein pressure before modeling, during modeling, and four-, eight-, and twelve- weeks after modeling, respectively. Then we evaluated the effectiveness of the model comparing values of data with those data obtained before modeling started, which were regarded as the normal values. The results showed that the portal vein pressure rose by 2. 5 times after the solution administrated instantly as much as that before modeling, and maintained at 1. 5 times after 4 weeks. This method presents an easy operation, low animal mortality and reliable model of portal hypertension. Its less abdominal adhesions and its ability in keeping normal anatomic structure specially make it suit for surgical research of portal hypertension.

This article describes the progress of developing the training base and training methods for bronchoscopists at Changhai hospital in recent years,and then discusses the potential issues and solutions that might occure in the course of training,and finally explores the model and methodology to optimize the training program for Chinese bronchosocpists.

A device of extrahepatic portacaval shunt is introduced. This device is composed of the daughter and parent magnets and the vascular interventional operation equipment. It is based on the principle of magnetic compression technology, through the intervention approach the daughter and mother magnet are moved to the portal vein and inferior vena cava, respectively. Then the two magnets attract and compress the vessel walls of portal vein and inferior vena cava. Two weeks later, the magnets are detached from the vessel wall with a RUPS-set and the portacaval shunt is established. It is mainly used for the treatment of portal hypertension. It belongs to the interventional operation, there is no any foreign body remaining after the portacaval shunt is established, which can maintain long-term patency. Futhermore the portacaval shunt will not be expanded, therefore it can significantly reduce the incidence of hepatic encephalopathy.

Objective:To investigate age related changes in urodynamic parameters of women with uri-nary incontinence.Methods:From May 2008 to October 2015,a total of 214 patients diagnosed with urinary incontinence in Peking University People’s Hospital was involved in this study.Average age was (56.97 ±10.68)years,ranging from 30 to 82 years,and average history was (8.44 ±8.85)years, ranging from one month to 50 years.Urodynamic examinations of each patient were taken before operation routinely in Department of Urology,Peking University People’s Hospital.The urodynamic study was composed of non-invasive and invasive procedures.Analysis included maximal flow rate (Qmax ),average flow rate,time to Qmax ,voiding time,detrusor pressure at Qmax ,maximal detrusor pressure,voided volume,post-void residual urine volume (PVR),the total capacity of bladder,first-,strong-,and urge-desire to void,cough leak point pressure (CLPP),and Valsalva leak point pressure (VLPP).Patients were divided into four groups according to age,Kolmogorov-Smirnov test and one-way ANOVA were used for data analysis.Results:A total of 214 patients were enrolled in this study.The data of Qmax ,average flow rate,voided volume,and total capacity of bladder decreased with statistical significance.The value of residual urine volume and voiding time increased without statistical significance,while the value of maximal detrusor pressure decreased.Conclusion:Urodynamic examination data of females with urinary incontinence changes along with the elapse of age,which was mainly observed as age ascends,and the changes in urodynamic parameters of women with urinary incontinence suggest that the value of Qmax , average flow rate,voided volume,and total capacity of bladder decreased significantly,while the value of PVR and the voiding time increased and the value of maximal detrusor pressure decreased.

[Summary] Sixty-one patients suffering from pituitary apoplexy( PA) were mainly diagnosed according to pathologic findings, and were collected from case record, pathology, and MRI databases. They were classified into 4 types according to the clinical condition: the insidious type was characterized with only positive pathological findings;the asymptomatic type had both positive pathologic and MRI findings; the subacute type had PA associated symptoms longer than 2 weeks; and the acute type had PA associated symptoms for 2 weeks or less. The latter 2 types had positive pathological and MRI findings additionally. The basic lesions, acute or chronic symptoms, endocrinopathies and MRI findings were compared among 4 types. Results showed as followed. In all patients, there were headache(60. 7% ), blurred vision(55. 7% ), vomiting(21. 3% ), and dizziness(14. 8% ). Apoplexy associated symptoms comprised severe headache (24. 6% ), rapid vision loss (29. 5% ), and blepharopotosis or diplopia (9. 83% ). Insidious, asymptomatic, subacute, and acute types were composed of 15 (24. 6% ), 9 (14. 8% ), 19 (31. 1% ), and 18 (29. 5% ) cases, respectively. Aging and intracranial space-occupying symptoms as first complaint showed increasing trend from mild to severe types(both P<0. 05), while in chronic course it showed decreasing trend(P<0. 05). Acute massive symptoms(P<0. 01), and non-functional tumor(P<0. 01) in the 2 clinical types were much more frequent than in the two mild types. Half or more pituitary-target glands showed impaired functions in each type, and the impairment showed increasing trend through mild to severe types(P<0. 01). The present study provided a brief typing system in order to expand PA concept to a wider span covering various conditions. Some differences in tumor composition and endocrinopathies existed among the four types.

A new system of blood flow block for control of bleeding in abdominal operation is composed of an abdominal magnetic blocking unit, an abdominal external electromagnet unit and other non-magnetic operation instrument. The abdominal external electromagnetic unit is placed in advance in the operation bed. The abdominal magnetic blocking unit can be placed directly on the ventral of the large vessels when need to blocking the abdominal large vessels during the operation. According to the non-contact suction characteristics of magnetic materials, the two magnetic units will attract each other and compression the vessels. Using this system for vascular occlusion does not need clear exposure and without separating vessel. There is the advantage of rapid, accurate and reliable for the system.
