Objective: To evaluate the clinical value of CT or type-B ultrasound image-guided percutaneous core biopsy for diagnosis of pancreatic masses. Methods: A total of 194 cases found with pancreatic lesions by type-B ultrasound, CT or magnetic resonance imaging (MRI) underwent CT or ultrasound image-guided percutaneous core biopsy. The tissue samples were examined histologically. Results: Of 194 cases, 90 underwent CT image-guided biopsy with an average of 2.8 passes and 104 underwent type-B ultrasound image-guided biopsy with an average of 2.3 passes. The overall accuracy of diagnosis was 97.9% (190/194). There were 172 cases (90.5%) of malignant lesions, including ductal adenocarcinoma in 160 cases, cystadenocarcinoma in 4 cases, mucinous adenocarcinoma in 4 cases, malignant stromal tumor in 2 cases, and non-Hodgkin's lymphoma in 2 cases. Meanwhile, there were 18 cases (9.5%) of benign lesions, including serous cystadenoma in 4 cases, mucinous cystadenoma in 2 cases, tuberculosis in 2 cases, chronic pancreatitis in 5 cases and pancreatic pseudocyst in 5 cases. After biopsy, 20.6% (40/194) of the cases complained of abdominal pain (10 were moderate, 30 were mild) and 82.5% (160/194) of the cases had a transient elevation of serum amylase. No severe complications occured. Conclusion: CT or type-B ultrasound image-guided percutaneous core biopsy for diagnosis of pancreatic masses is a convenient and safe method with a high positioning and diagnostic accuracy.

Objective To investigate the reversal effect of triazole antifungal itraconazole,fluconazole combined with adriamycin on multidrug resistance in leukemia cells.Methods Human chronic myelogenous leukemia adriamycin resistant cell lines K562/ADR cells were incubated with itraconazole,fluconazole,or PSC833 (positive control) combined respectively with adriamycin.CCK-8 assay was used to assess cell proliferation of K562/ADR.The mean fluorescence intensity of intracellular ADR was measured by flow cytometry.The marker of DNA damage γH2AX was detected by Western blot.Results 1 μg/ml itraconazole and 0.5 μg/ml PSC833 can decrease K562/ADR IC50 of adriamycin from 38.30 μg/ml to 8.59 μg/ml and 24.64 μg/ml in a dose-dependent manner.K562/ADR cells were incubated with 1 μg/ml itraconazole or 0.5 μg/ml PSC833 combined respectively with adriamycin for 3 h and 6 h,the mean fluorescence intensity of intracellular ADR were increased 1.54-fold (3 h),1.50-fold (6 h) or 5.97-fold (3 h),5.83-fold (6 h).Itraconazole or PSC833 combined with adriamycin significantly increase the expression of γH2AX in K562/ ADR cells.Conclusion Itraconazole can recover adriamycin sensitivity of K562/ADR by increasing the concentration of intracelullar adriamycin and synergistically increasing DNA damage,but not for fluconazole.

Pancreatic cancer is a kind of highly malignant aggressive cancers.Perinearal growth is one of the importcant biological characteristics of pancreatic cancer.Perineural invasion is an independent prognostic indicator of its prognosis.However,the mechanism has not yet completely clear.The pancreatic cancer perineural invasion mechanism research has been the focus of scholars to discuss,however it' s difficult to break through.Therefore,the discussion pancreatic violation of the peripancreatic neural mechanism for early clinical find,early treatment is essential.The mechanisms of pancreatic cancer research,from all kinds of adhesion molecule to the nerve growth factor,related ligand protein path to susceptibility gene expression,have been reported largely,which helps enhance people' s awareness of peripancreatic neural invasion.At the same time,perineural invasion in the early detection of disease,prolonging survival period and improving the quality of life has important significance.Now the progresses of reviews in recent years are discussed as follows.

Objective To investigate the relationship between cysteinyl leukotriene and clinical response to antileukotriene treatment,and to help select a clinical pharmacologic scheme.Methods Seventy-eight cases with acute mild-moderate asthma were treated with montelukast in a four-week trial.Asthmatic symptom score,usage of ?_2 receptor agonist,percentage of eosinophil,serumal IgE concentration,spirometry and urinary leukotriene E_4(uLTE_4)were measured pre- and post-treatment.Logistic analysis was used to access the various clinical parameters correlated with the response to montelukast.Results There were 48 responders and 30 nonresponders.The uLTE_4 level from the responders was higher than that of nonresponders(P0.05).Subjects with a uLTE_4 level of ≥1 200 pg/mL were11.5 times more likely to respond to montelukast than those with

Objective To investigate the relationship between the number of eosinophil(Eos)and level of eosinophil cationic protein(ECP)in induced sputum and asthma severity and their value of differential diagnosis.Methods From July 2002 to June 2004,59 asthmatic patients were selected in the People Hospital of Wuhan University.The number of eosinophil and level of ECP were measured by Wrights' stain and Immuno-CAP System.The lung function was also evaluated.The same index was measured in 20 patients with COPD and 10 healthy subjects as control.Results The number of eosinophil in induced sputum in asthmatic patients negatively correlated with FEV_1%(r=-0.65,P

Objective To study the alterations in neurobehavior of rats with diffuse axonal injury(DAI) and to evaluate the potential role of basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to build the DAI model.An injection of bFGF subdurally and subcortically was given to the bFGF therapeutic group(n=60).Besides,normal control(n=20) and injured control group(n=60) were established.The elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were adopted to examine the motor and memory abilities.After the implantation of skull electrodes,P3-like potential was explored in rats before and after injury. Results After DAI,the scales of the elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were decreased,and the rats in the bFGF therapeutic group presented a better behaviour in the early stage.The latency of P3-like potential prolonged significantly in rats with DAI,with the P3-like potential in the injured control group longer than that in the bFGF therapeutic group(P

Objective To study the alterations in pathology and immunohistochemistry in rats with diffuse axonal injury(DAI) and the effects from basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to produce DAI in rats.In the treatment group(n=60),bFGF was injected subdurally and subcortically.Besides,normal control group(n=20) and injury-control group(n=60) were also established.The pathological changes were observed by light microscopy and electromicroscopy,and the expression of brain-derived neurotrophic factor(BDNF),growth associated protein-43(GAP-43) and glial fibrillary acidic protein(GFAP) were also examined by immunohistochemistry. Results Typical pathological changes were observed in the basal portion of pons,corpus callosum and white matter of cerebral hemisphere in the rats with DAI.And an upregulation of GFAP,GAP-43 and BDNF was also found.In the treatment group,better outcomes of pathological changes were observed.bFGF increased the expression of BDNF and GAP-43,while inhibited the immunoreactivity of GFAP. Conclusion Topical application of bFGF can improve brain tissue regeneration and speed function recovery in rats with DAI,though its long-term effect warrants further study.

Objective To evaluate the feasibility and efficiency of endoluminal catheter-based ultrasonography on diagnosis of upper urinary tract diseases. Methods From January 1997 to December 2006,the clinical data of upper urinary tract of 68 cases who examined by endoluminal uhrasonography with a 10 MHz miniature ultrasound transducer and a 8 F outer catheter were reviewed.There were 30 males and 38 females aged 17-81 years with an average of 58 years.The renal pelvis and its surrounding structures were examined in 48 cases and the ureter and its surrounding structures were examined in 20 cases.The total of 73 sides had experienced by this technique.The accuracy of diagnosis with endoluminal catheter-based ultrasonography was evaluated by the pathology and clinical follow-up. Results The total success rate of the ultrasound probe introduced into ureter was 91%in 68 cases.In the pelvis group it was 96%(46/48)and the ureter group 80%(16/20).In renal pelvis abnomalities,the detectable rate of abnormal by ultrasonography was 89%(41/46).The total detectable rate in ultrasound probe group was significantly higher than that in other equipment groups(P＜0.01).The detectable rate of ultrasonography on ureter disease was 75%(12/16). Conclusion Endoluminal catheter-based ultrasonography is an effective,safe technique for the diagnosis of diseases in the upper urinary tract.

OBJECTIVETo explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.

METHODSThe clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.

RESULTSAll patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).

CONCLUSIONThe preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.
