FAT in the trunk increases more obviously than that in other parts of the body in both males and females. The change of distribution of FAT and LEAN can obviously influence BMD.

Objective To evaluate the diagnostic value of 2D-FIESTA sequence of MRI in the detection of the biliary tract lesions in infant and young children patients(less than 3 years).Methods 8 infant and young children patients were examined by MRI to evaluatetheir biliary tract.Images were obtained with a 1.5T whole body MRI system(GE Medical System,Milwakee,Wis,USA),using theCARDIAC coil.The patients were sedated by chloral hydrate orally or by pentobarbital sodium intravenously.No contrast agents wererequired.All of the axial,coronal and sagittal images were reviewed on an independent workstation and maximum intensity projection(MIP) and multiplanar reformations(MPR) techniques were applied.Results The 2D-FIESTA pulse sequence results in images in which the hepatic vascular structures and the biliary tract were highlighted.In this way,a clear visualization of the hepatic vessels and biliarytract could be obtained in all 8 cases.MRI could demonstrate the anatomy and pathology of post-transplantation changes in 3 patients,choledochal cysts in 2 patients,anomalous connection between the bile and pancreatic ducts in 1 patient.All the abnormalities were proved by operation.2 examinees were diagnosed normal by MRI and were confirmed by follow-up.Conclusion 2D-FIESTA is a fast sequence that allows the high quality images to be generated without breath-hold and without administration of contrast material.It has a potential wide application in the evaluation of biliary tract in the infant patients.

Objective To investigate the clinicopathologic features and prognostic analysis of intrahepatic mucinous cholangiocarcinoma (IMCC) and intrahepatic cholangiocarcinoma (ICC).Methods The retrospective cohort study was adopted.The clinicopathological data of 20 patients with IMCC and 51 patients with ICC who were admitted to the Fujian Provincial Hospital from March 2003 to March 2014 were collected.The observation indicators included (1) clinicopathologic features:gender,age,clinical symptoms (fever,jaundice,abdominal pain and peritoneal effusion),preoperative laboratory examination [alanine transaminase (ALT),aspartate transaminase (AST),direct bilirubin (DBil),carcinoembryonic antigen (CEA),CA19-9 and alphafetoprotein (AFP)],operation methods (radical resection,palliative resection) and pathological features (tumor location,lymph node metastasis,vascular invasion and pathological stage).(2) The follow-up of outpatient examination and telephone interview was performed to detect the survival of patients up to March 2015.Measurement data with normal distribution were represented as x-± s and comparison between groups was analyzed using t test.Count data were analyzed using the chi-square test.The survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.Result The numbers of patients with fever,jaundice,elevated level of AST and DBil,lymph node metastasis,vascular invasion and numbers of patients with stage 0,Ⅰ,Ⅱ,Ⅲ,Ⅳ were 13,11,10,11,3,1 and4,6,2,6,2 with IMCC,12,10,9,2,22,36 and 0,14,5,3,29 with ICC,respectively,showing statistically significant differences in the above indicators (x2=10.830,8.639,7.672,25.059,8.036,24.765,26.601,P ＜ 0.05).All the patients were followed up for a median time of 14 months (range,1-118 months).The survival time and 1-,3-,5-year survival rates were (55 ± 8)months,94.4％,44.0％,16.7％ in 20 patients with IMCC and (30 ±6) months,36.5％,12.5％,4.0％ in 51 patients with ICC,respectively,showing a statistically significant difference (x2 =8.126,P ＜ 0.05).Conclusion The patients with MICC are more easily complicated with fever,jaundice and liver dysfunction,while they have less lymph node metastasis and vascular invasion,earlier pathological stage and better prognosis compared with patients with ICC.

BACKGROUND: Studies indicated that lipid peroxidation due to increase of free radical is the key factor of ischemia/reperfusion injury.Shinyleaf pricklyash root extracts, rutaceae plant, is bitter in taste, no stimulation, which has the effects of promoting qi, relieving pain, promoting blood circulation by removing blood stasis, dispelling wind and dredging collaterals and antioxidation.OBJECTIVE: To observe the influence of nitidine chloride on myocardial ischemia/reperfusion injury in rats and analyze its mechanism.DESIGN: Randomized controlled study.SETTING: Departmentof Pharmacology and Department of Chemistry,Guangxi Medical University.MATERIALS: A total of 60 healthy Wistar rats were selected, half male and half female, with the body mass of 250-300 g. Nitidine chloride was provided by Department of Chemistry, Guangxi Medical University, batch number 20050609. MS4000U biological signal quantitative record analysis system, 722N evident spectrophotometer, hydrochloric acid verapamil (batch number 020701, 2 mL in each), malondialdehyde (MDA) and superoxide dismutase (SOD) kit were purchased from Guangzhou Longfeida Technology Co., Ltd., Shanghai Precision Scientific Instruments Corporation, Shanghai Harvest Pharmaceutical Co, Ltd. and Nanjing Jiancheng Bioengineering Institute, respectively. Hitachi 7170A full automatic biochemistry analyzer was also applied.METHODS: The experiment was performed at the Department of Pharmacology and Department of Chemistry, Guangxi Medical University between June 2004 and May 2006. ①Totally 60 healthy Wistar rats with normal ECG (half male and half female) were randomly divided into 6 groups:sham operation group, model group, 2, 1, 0.5 mg/kg nitidine chloride groups, positive control group with 10 rats in each group. The rats in the sham operation group received threading without deligation, and 90 minutes later the experiment was accomplished. Other 50 rats received left anterior descending branch of coronary artery deligation, ischemia for 30 minutes reperfusion for 60 minutes. 2 mg/kg verapamil, 2,1,0.5 mg/kg, 5 mL/kgnitidine chloride, saline of the same volume were injected into femoral vein in rats of the positive control group, different doses nitidine chloride groups and model group, respectively 10 minutes before deligating left anterior descending branch of coronary artery. ②Monitoring was conducted successively with standard limb Ⅱ lead ECG when performing reperfusion. Type,incidence rate and duration of cardiac arrhythmia were recorded within 60minutes. Change of ST segment was also recorded after reperfusion for 15minutes and 60 minutes. ③At the end of experiment, serum myocardial enzymology indexes were measured wi th full automatic biochemistry analyzer.MDA content and SOD activity in myocardial tissues were examined with thiobarbituric acid(TBA) method and xanthine oxidase (XOD) method, respectively. ④Measurement data and enumeration data between two groups were compared with t test and x2 test. MAIN OUTCOME MEASURES: Occurrence of cardiac arrhythmia, ECG ST segment elevation, change of serum myocardial enzymology indexes, MDA content and SOD activity of myocardial tissues in rats of each group.RESULTS: A total of 60 rats were involved in the result analysis. ①Degree of cardiac arrhythmia and ECG ST segment elevation of rats: The emergency time of cardiac arrhythmia in 1 and 2 mg/kg nitidine chloride groups was significantly later than that in the model group (P ＜ 0.05,0.01). The duration of cardiac arrhythmia in the 1 and 2 mg/kg nitidine chloride groups and positive control group was obviously shorter than that in the model group (P ＜ 0.05-0.01). The incidence rates of various kinds of cardiac arrhythmia were markedly less than those in the model group (P ＜ 0.01). The degree of ST segment elevation at reperfusion for 15 and 60 minutes was remarkably lower than that in the model group (P ＜ 0.05-0.01). ②Serum myocardial enzyme level: It was significantly higher in the model than the sham operation group after 60-minute myocardial ischemia and reperfusion (P?.01). Activity of myocardial enzyme in the 1 and 2 mg/kg nitidine chloride groups was remarkably lower than that in the model group (P ＜ 0.01,P ＜ 0.05). The level of myocardial enzyme decreased with the increase of nitidine chloride. It was lower significantly in the positive control group than the model group (P ＜ 0.05-0.01 ). ③SOD activity of myocardial tissues: It was markedly lower in the model group than the sham operation group after 60-minute myocardialischemia and reperfusion (P ＜ 0.01); It was dramatically higher than in the 1 and 2 mg/kg nitidine chloride groups than the model group (P ＜ 0.01). The activity also increased with the increase of nitidine chloride. ④MDA content of myocardial tissues: It was distinctly higher in the model group than the sham operation group after myocardial ischemia reperftsion for 60 minutes (P ＜ 0.01). It was remarkably lower in the 1 and 2 mg/kg nitidine chloride groups than the model group (P ＜ 0.01). The content decreased with the increase of nitidine chloride. It was obviously lower in the positive control group than the model group (P ＜ 0.05 ).CONCLUSION: ①1 and 2 mg/kg nitidine chloride can reduce the incidence rate of cardiac arrhythmia in rats with myocardial ischemia and reperfusion, postpone the emergence time of cardiac arrhythmia and shorten its duration, decrease the degree of ST segment elevation after reperfusion for 15 minutes and 60 minutes, which have similar effect with verapamil.② 1 and 2 mg/kg nitidine chloride can reduce the release of myocardial enzyme, relieve the severity of oxygen-derived free radicals injury, and has the effect of protecting myocardial injury during ischemia-reperfusion, in which represents a dose-dependent effect.

OBJECTIVE: To evaluate the influence of fewer courses and prolonged intervals of chemotherapy on survival rate of advanced non small cell lung cancer (NSCLC) patients treated by sequential chemo-radiation therapy combined with traditional Chinese medicine (TCM). METHODS: From Jan. 2000 to Dec. 2001, 54 untreated advanced NSCLC patients (2 stage IIIa, 18 stage IIIb, 34 stage IV) were treated by sequential chemo-radiation therapy combined with TCM. The courses of chemotherapy were reduced and the intervals of chemotherapy were longer than that of the standard regimen. The efficacy and survival rate were documented and the prognostic factors were analyzed. RESULTS: Complete remission (CR) was observed in 1 case and partial remission (PR) in 20 cases. The overall objective response rate was 40.4%. Median survival was 15.3 months, 1-, 2- and 3-year survival rate were 53.7%, 28.9% and 9.6% respectively. The median survival of stage III and IV were 21.8 months and 12.5 months respectively. The 1-, 2-, and 3-year survival rates of stage III were 65.0%, 49.5%, 24.7% and that of stage IV were 47.0%, 23.3%, 0%, respectively. The quality of life was improved in most of the patients. Cox's proportional hazards regression showed that improved quality of life and treatment of TCM were the significant prognostic factors of overall survival. CONCLUSION: Chemotherapy and radiotherapy combined with TCM is beneficial to extending the interval of chemotherapy, improving the quality of life, and increasing the survival rate of advanced NSCLC patients.
