Objective:To study changes of blood glucose and lipid levels in patients with impaired glucose tolerance.Methods:According to 1997 ADA standard,496 patients with impaired glucose tolerance(IGT group) and 1514 persons whose glucose tolerance was normal were selected and their levels of fasting blood glucose(FBG),cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C),and ratio between TC and HDL-C were calculated and compared.Results:Significant differences were observed between patients and controls in the levels of FBG ( P

Purpose:To assess MRI and MRS features of intracranial hemangiopericytoma.Materials and Methods: The imaging data of MRI and MRS were analyzed retrospectively with seven cases of hemangiopericytoma.MR examinations were performed on seven cases,MRS on 4 cases.Results: The position of lesions were all located at the supratentorial area and extraaxial region.Six masses were lobulated in shape.Of seven cases,3 cases were isointense with cortical gray matter,3 iso- and hypointense,l hypointense with localized hyperintense resulted from hemorrhage on T1WI: 2 cases demonstrated isointense with cortical gray matter,4 iso- and hyperintense,1 complex hyperintense on T2WI.Five tumors had prominent internal or surficial serpentine signal voids.3 tumors showed homogeneous marked enhancement,4 heterogeneous enhancement.MRS of four tumors showed marked elevated Cho peak,Lip peak and diminished or disappeared NAA peak.Two cases were companied with marked elevated MI peak.Conclusion:The MR imaging findings of hemangiopericytoma has some characteristics,which can help differentiation from meningioma combined MRS.

Objective To investigate the CT characteristics of anaplastic thyroid carcinoma and evaluate the diagnostic value of CT in this disease.Methods The CT findings of 10 patients with pathologically proved anaplastic thyroid carcinoma were retrospectively reviewed.The patients included 7 females and 3 males.Their age ranged from 25.0 to 78 years with median of 61 years.Multi-slices plain and post contrast CT scans were performed in all patients.Results Unilateral thyroid was involved in 6 patients.Unilateral thyroid and thyroid isthmus were both involved in 2 patients due to big size.Bilateral thyroid were involved in 2 patients.The maximum diameter of anaplastic thyroid carcinoma ranged from 2.9-12.8 cm with mean of (4.5 ± 1.4) cm.All lesions demonstrated unclear margins and envelope invasion.The densities of all lesions were heterogeneous and obvious necrosis areas were noted on precontrast images.Seven lesions showed varied calcifications,and coarse granular calcifications were found in 5 lesions among them.All lesions showed remarkable heterogenous enhancement on post-contrast CT.The CT value of solid portion of the tumor increased 40 HU after contrast media administration.The ratios of CT value which comparing of the tumor with contralateral sternocleidomastoid muscle were 0.69-0.82 (0.76 ± 0.18)and 1.25-1.41 (1.33 ± 0.28)on pre and post CT,respectively.Enlarged cervical lymph nodes were found in 6 cases (60.0％).It showed obvious homogeneous enhancement or irregular ring-like enhancement on post-contrast images and dot calcifications were seen in 1 case.Conclusions Relative larger single thyroid masses with coarse granular calcifications,necrosis,envelope invasion,remarkable heterogeneous enhancing and enlarged lymph nodes on CT are suggestive of anaplastic thyroid carcinoma.

Objective To evaluate the protective effects elicited by ClpP fusion protein in animal protection tests. Methods Pneumococcal antigens were purified from recombinant Escherichia coli express-ing CIpP cloned gene. 6- to 8-week-old female BALB/c mice were immunized intraperitoneally with either ClpP or PBS plus alum. Every mouse received three doses of 20 μg antigen or PBS in 100 mg of alum adju-vant at 14 d intervals. Sera were collected from mice and analyzed by ELISA 1 week after the third immuni-zation, Intraperitoneal-challenge experiments with 12 different serotypes of Streptococcus pneumoniae were carried out 2 weeks after the third immunization, and we compared their median survival times and survival rates respectively by Mann Whitney U test and Fisher exact test. Results ELISA analysis demonstrated high titer specific antibody responses to ClpP. The median survival times for mice immunized with ClpP pro-tein antigens in adjuvant were significantly longer than those for mice that received the adjuvants alone. Con-clusion A highly expressed recombinant ClpP protein has been successfully obtained and proved to exert the protection against invasive pneumococcal infection without relation of serotype, suggesting ClpP can be a promising candidate vaccine.

Objective To assess the reproducibility of brain activation by functional MR imaging during electroacupuncture stimulation at PC6(neiguan).Methods Six healthy adult volunteers participated in three identical scan sessions during different interval time.Each scan session consists of two functional tasks,an electroacupuncture stimulation(2 Hz) at PC6 and a control task of simple finger tapping.The reproducibility of brain responses was analyzed in terms of the overlap ratio of active volume within sessions and the ICC of active signal intensity in ROIs.Results The Roverlap of the simple finger tapping task(34.24?9.49) was significantly higher than that of the electroacupuncture stimulation task(13.23?14.21).The range of ICC of ROIs in the simple finger tapping task(0.69-0.80) was significantly higher than that of the electroacupuncture stimulation task(0.18-0.68).The results above showed that the reliability of brain activation in the finger tapping task group was higher than that in the electroacupuncture stimulation task group.The active intensity of ROIs in the simple finger tapping task was significantly higher than that in the electroacupuncture stimulation task,indicating the signal to noise ratio of brain activation in the finger tapping task group was higher than that in the electroacupuncture stimulation task group.Conclusion In contrast to the relatively reliable activation evoked by the simple finger tapping task,the activation evoked by electroacupuncture stimulation task was much more variable.The main possible reason is that the relatively low signal to noise ratio of brain activation on fMRI and low sensitivity caused the lower reproducibility of electroacupuncture stimulation task.The group analysis in combination with the individual functional data may be utilized to improve the reproducibility of fMRI evoked by electroacupuncture stimulation at PC6(neiguan).

Objective To assess the clinical value of 16-slice spiral CT in the diagnosis of multiple carcinomas in unilateral upper urinary system. Methods The imaging findings of 16-slice spiral CT of 10 patients suffered from multiple carcinomas in the unilateral upper urinary system proven pathologically were analyzed. Results Among 10 cases, 6 cases had multiple carcinomas in the unilateral renal pelvis and ureter and simultaneously involved urinary bladder, 3 cases had the multiple carcinomas in the unilateral renal pelvis and ureter, and 1 case had the multiple carcinomas in the lower and middle ureter and involved urinary bladder. CT images clearly presented the thickened irregular renipelvic and ureteric wall with stenosis and/or mass in the renipelvic and ureteric cavity. The urinary bladders involved by carcinoma were depicted as thickened irregular wall of urinary bladder or the mass in the wall of urinary bladder. The images of curved reconstruction clearly showed the extention of the multiple carcinomas and the changes of the urinary tract involved by the multiple carcinomas. Enlarged retroabdominal lymph nodes were detected in 3 cases simultaneously, and 2 of them were proved metastasis, the imaging findings were absolutely identical to that of the operation and pathological examination. Conclusion Sixteen slice spiral CT can clearly and accurately depict the location and extention of multiple carcinomas in the unilateral upper urinary system.

Objective To investigate the relationship between glutathione S-transferases P1(GSTP1)Ile105Val and glutathione S-transferases M1(GSTM1)single nucleotide polymorphisms(SNP) and the sensitivity to chemotherapy among patients with ad-vanced non-small cell lung cancer(NSCLC) .Methods We used gene sequencing analysis to determine the SNP of GSTP1 Ile105Val and PCR analysis to GSTM1 in DNA from peripheral lymphocytes of NSCLC patients .Totally 89 patients with NSCLC were trea-ted with platinum-based chemotherapy ,and clinical response was evaluated after 2 cycles .The association between GSTP1 Ile105Val and GSTM1 SNP and chemosensitivity were analyzed .Results The overall response rate was 29 .2% .Chemotherapy re-sponse did not show statistically significant differences between the wild genotypes and the variant genotypes for the GSTP1 Ile105Val and GSTM1 gene(P>0 .05) .Conclusion The polymorphisms of GSTP1 Ile105Val and GSTM1 may be not associated with sensitivity to chemotherapy in NSCLC patients .

Purpose To investigate the CT and CTA findings of intracranial hemanigoperiocytoma. Materials and Methods The CT and CTA data of 7 cases of pathologically confirmed intracranial hemanigoperiocytoma were retrospectively reviewed. Results All the 7 cases were extra-axial and supratentorial location. Six were lobulated and 1 were oval in shape. Three were iso-density to the parenchyma and 4 were inhomogeneous with clear margins. Five had perifocal edema. On contrast scan, all showed homogeneous or inhomogeneous enhancement. Five had dilated tortuous vessels and 4 were identified as feeding artery inside or around the tumors. Conclusion The CT findings of intracranial hemanigoperiocytoma are similar to meningioma but CTA is helpful for the differential diagnosis.
