Objective To investigate the guidance of a new classification on the treatment methods selection for cystic dilation of bile duct (CDBD).Methods The clinical data of 213 patients with CDBD who received treatment according to the Todani 2003 classification at the Peking Union medical College Hospital from September 1968 to July 2013 were retrospectively analyzed.The CDBD was reclassified with a new classification proposed by Dong Jiahong et al,and the guidance of the new classification on the treatment methods selection for CDBD was analyzed.Patients were followed up via out-patient examination and telephone interview till August 2013.Results Of the 213 patients,139 were with Todani type Ⅰ CDBD (type C CDBD of the new classification) ; 3 were with Todani type Ⅱ CDBD (type C1 CDBD of the new classification) ; 1 was with Todani type Ⅲ CDBD (type E CDBD of the new classification); 52 were with Todani type Ⅳa CDBD (35 with type D1 and 17 with type D2 CDBD of the new classification) ; 1 was with Todani type Ⅳb CDBD (type C CDBD of the new classification) ; 8 were with Todani typeⅤ-Ⅰ CDBD (type B CDBD of the new classification) ; 9 were with Todani type Ⅴ-Ⅱ CDBD (type A CDBD of the new classification).Eighteen patients did not receive the surgical treatment.Of the 195 patients who received surgical treatment,patients with type C and D CDBD of the new classification took a large proportion.Patients with type C CDBD of the new classification received cystectomy,biliary cyst resection,Rouxen-Y cholangiojejunostomy or internal drainage.Patients with type D CDBD of the new classification received extrahepatic biliary cyst resection,Roux-en-Y cholangiojejunostomy.Patients with severe intrahepatic disease and with type D1 CDBD of the new classification received concomitant left hemihepatectomy or pancreaticoduodenectomy.Patients with type A1 CDBD of the new classification received right hemihepatectomy.Patients with type A2 CDBD of the new classification were cured by conservative treatment after split liver transplantation.Patients with type B1 CDBD of the new classification received left hemihepatectomy and Roux-en-Y cholangiojejunostomy.Patients with type B2 CDBD of the new classification received bile duct stone extraction.There was 1 patient with type E CDBD,and partial resection of the CDBD ± bile duct reconstruction was carried out.Pancreatic fistula,biliary fistula,reflux cholangitis,cholangitis and anastomotic stricture were detected on 74 patients,and they were cured by conservative treatment or lithotomy.A total of 187 patients were followed up with the median time of 85 months (range,1-432 months).One hundred of seventy-five patients recovered well,and 12 patients with canceration of the bile duct died of tumor metastasis at postoperative 1-282 months.Conclusion This new classification simplifies the typing of extrahepatic bile duct dilation,refines the typing of intrahepatic bile duct dilation,and has better guidance for surgical treatment.

Objective To improve diagnosis accuracy of pineocytoma (PC) by joint analysis of CT,MRI imaging features and differential diagnosis with other lesions in pineal region.Methods Totally 6 pineocytoma patients confirmed surgically and pathologically had their clinical history,CT and MRI data collected and analyzed on lesion morphology,cystic solid changes,existence of necrosis,complications of hemorrhage and or calcification,MRI and enhanced scan of solid component,complications with hydrocephalus and etc.Results Plain scan found 1 case of solid nodule and 5 cases of cystic-solid nodules,2 cases with clearly-bordered lesions and 4 one not as well as 4 cases with significant hydrocephalus and 2 ones with light hydrocephalus.Enhanced scan showed 5 cases of moderate to marked enhancement and one case with no obvious enhancement.CT examination proved there were 1 case of calcification and 1 case of hemorrhage.Conclusion Pineocytoma has the characteristics of benign tumor,and has to be differentiated with other tumors frequently occurring in this region in case of obvious clinical signs due to crushing brain parenchyma or blocking aqueduct cerebri by oversized lesions.

Objective To investigate the effect of obesity on physical stamina of college students.Methods The physical stamina and obese status of 7353 college students were measured. The relationship between obese degrees and the scores of step trial, vital capacity, grip, standing long jump was analyzed.Results The male's and female's vital capacity score was obesity students > pre-obesity students > normal students > thin students ( P<0.01). The male's step trail score was the normal body weight students and pre-obesity students > obese students ( P<0.05). The male and female's standing long jump score was normal students > pre-obesity students > obesity students ( P<0.05). The male and female's grip score was obesity students > pre-obesity students > normal students > thin students ( P< 0.05 ).Conclusion The lung function and the arm power of college students are increasing with the rise of obese degrees. The heart function and breakout force are decreasing with the rise of obese degrees.

BACKGROUND:Traditionally, forced expiratory volume in one second (FEV1) was used to evaluate exercise response of patients with asthma; however, patients obviously had panting after exercise, so FEV1 was affected commonly. Impulse oscillometry (IOS) is a new technique for measuring respiratory impedance that do not require maximal inspiration and forced expiration.OBJECTIVE: To study airway resistance with IOS before and after exercise in healthy and asthmatic patients and investigate the significance of exercise excitation and IOS assessment.DESIGN: Synchronically non-randomized case contrast study.SETTING: Department of Respiratory Medicine, East Hospital Affiliated to Tongji University.PARTICIPANTS: A total of 14 male patients with bronchial asthma who were regarded as the asthmatic group were selected from Department of Respiratory Medicine of Shanghai East Hospital from January to October 2006. They were in a clinical stationary phase. Another 14 male healthy subjects were selected as the control group and ages of all subjects ranged from 29 to 50 years. All subjects provided the confirmed consent.METHODS: IOS was used to measure basic value of respiratory resistance, and then subjects underwent exercise challenge. Nose of subjects was clipped breathing through mouth. Within 3-4 minutes, heart rate was increased to 90% and maintained for 6 minutes during challenge. Respiratory resistance was repeatedly measured at 1, 5, 10, 15 and 20 minutes after exercise, including airway hyperresponse (AHR), total respiratory resistance, central resistance, peripheral resistance and resonance frequency at 5, 20 and 35 Hz of pulse frequency, elasrtic resistance and inertia resistance (X5 and X35) at 5 and 10 Hz of pulse frequency. In addition, difference of AHR at 5 and 35 Hz was calculated, and change ratios of both Rcentral and Rperipheral were calculated as (highest value after exercise-baseline value)/baseline value × 100%.MAIN OUTCOME MEASURES: Basic value of respiratory resistance by using IOS and exercise challenge test.RESULTS: All 14 patients with bronchial asthma and 14 healthy subjects were involved in the final analysis. Peripheral resistance (Rperiphera) was significantly higher than central resistance (Rcentral) in asthmatic patients (P ＜ 0.01). The maximal increase of respiratory impedance occurred from 5 minutes to 10 minutes after exercise in asthmatics. Resonance frequency (Fres) of asthmatics before and after exercise was significantly increased than that of controls (P ＜ 0.01).Change ratios of Fres from asthmatics were higher than that from control group (P ＜ 0.01). After challenge, R5, R5-R20,Zrespir and X5 from asthmatics changed significantly than that from controls (P ＜ 0.01). The increment change value of After exercise Zrespir increased significantly, because obstruction of small bronchi during expiration and impedance increased abruptly. Air trapping was expressed in VT-Zrespir graph in 57.1% patients. There was no difference in the VT-Zrespir graph of controls before and after exercise.CONCLUSION: The main site of airflow obstruction was in small airways in asthmatics after exercise challenge. The general acceptance of IOS method was good among the asthmatic patients. The airway response of exercise challenge may be assessed more accurately with IOS that do not require a maximal inspiration and forced expiration.

ObjectiveTo observe the effect of cerebellar fastigial nucleus treated by electrical stimulation on patients with acute cerebral infarction.Methods140 cerebral infarction patients with hemiplegia were randomly divided into the experimental group and control group with 70 cases in each group.The experimental group was treated with routine drugs and electrical stimulating on cerebellar fastigial nucleus;the control group was only treated with routine drugs.The changes of motor function of limbs and activities of daily living of two groups were evaluated after treatment.ResultsAfter 21 days treatment,the score of Fugl-Meyer assessment of the experimental group was 39.2±(7.7) and that of the control group was 26.3±8.1.There was a significant difference between two groups(t=4.22,P<0.01).The score of Barther index of the experimental group was 43.8±8.4 and that of the control group was 29.7±7.5.There was also a significant difference between two groups(t=4.97,P<0.01).ConclusionThe electrical stimulation on cerebellar fastigial nucleus is a new effective way to treat acute cerebral infarction.
