Medulloblastoma was a common malignant, invasive neoplasm of the central nervous system occurring in children. This disease had the characteristics of easy recurrence and the prognosis remained relatively poor, which heavily influenced healthy and quality of life of children. In recent years, advanced magnetic resonance imaging (MRI) techniques such as diffusion weighted imaging (DWI), diffusion tensor imaging (DTI)and 1H- magnetic resonance spectroscopy (1H- MRS) were the new noninvasive technique of diagnostic imaging to be used in the diagnosis and prognosis of medulloblastoma, which showed very significant clinical value and made some new progress. In this study, we talked about the DWI, DTI and 1H-MRS used in medulloblastoma.

Objective To explore the changes of IL-12,IL-18,IL-10 in the pleural fluid and serum of tuberculosis (TB)patients during the disease course.Methods 60 TB patients were selected as test subjects in this study,all patients with pleural fluid and serum were taken for testing.The pleural fluid and serum IL -12,IL -18 IL-10 changes,more naive patients and patients with pleural effusion retreatment and serum IL -12,IL -18,IL -10 content differences were observed and analyzed.Results Both in the initial treatment or retreatment group of pa-tients,the IL -12 and IL -10 levels in pleural effusion were significantly higher than those in the serum,the differ-ences were statistically significant(all P =0.000),and IL -18 content of pleural effusion in a little early treatment group was lower than that of the serum,the differences was not statistically significant(P =0.151),and the IL -12 and IL -10 contents in the pleural fluid and serum were higher than the retreatment of patients previously untreated patients.The IL -12 level in pleural effusion of Ⅱ type patients was (3 025.80 ±1 324.75)pg/mL,which in the ser-um was (498.84 ±326.73)pg/mL,which in the pleural effusion was significantly higher than in the serum(P =0.020),and the IL -12 levels in pleural effusion of Ⅲ -TB and Ⅳ type TB patients were also significantly higher than those in the serum,the differences were statistically significant(all P =0.000).The IL -18 level in pleural effu-sion of Ⅱ type patients was (1 735.54 ±872.65)pg/mL,which in pleural effusion of Ⅲ patients was (754.63 ± 426.87)pg/mL,in pleural effusion of Ⅳ patients was (655.19 ±412.63)pg/mL or so,and serum IL -18 levels in patients with different types of pleural TB had no obvious rule,the differences were not statistically significant(P =0.998 4).The IL -10 level in pleural effusion of Ⅱ type patients was (29.35 ±8.46)pg/mL,which in pleural effu-sion of Ⅲ patients was (183.49 ±56.76)pg/mL,which in pleural effusion of Ⅳ patients was (162.95 ±52.43)pg/mL,the IL -10 content of pleural in different clinical types of TB patients was different,which were significantly high-er than those in the serum,the differences were statistically significant(P =0.000).Conclusion TB patients in the disease,pleural effusion IL -12 and IL -10 are significantly higher than the serum,and retreatment of patients with pleural effusion IL -12,IL -10 levels are significantly higher than the untreated patients,but IL -18 in serum has no significant variation in pleural fluid.

Mesoporous silica SBA-15 with a small organic molecular (1,8-Naphthalimide) was synthesized and used as matrix for MALDI-TOF-MS ( Matrix-assisted laser desorption/ionization time of flight mass spectrometry) analysis. A modified SBA-15 matrix, SBA-15-NA (1,8-Naphthalimide) was synthesized by covalently attaching SBA-15 to an 1 , 8-naphthalimide formed by 1 , 8-naphthalic anhydride and 3-( trimethoxysilyl) propylamine. The mass spectra obtained with SBA-15-NA exhibited less background interference ions, higher desorption/ionization efficiency, and higher peak intensity. The matrix was initially prepared in methanol and mixed with analyte at a 1∶1 volume ratio in vial. The solution of mixture was at a 10∶1 concentration ratio of matrix/analyte on a stainless steel target and allowed to air dry. The method was used to analyze various types of low molecular weight ( less than 500 ) chemical compounds such as monosaccharides, amino acids, phytohormones, drugs. Under the optimal conditions, it gave low detection limit of 1×10-9 g/L (Leucine, S/N=5) and good reproducibility (≤30%). The modified mesoporous silica materials have been employed in the urinary study for direct detection of metabolites.

[Objective] To observe the curative effect of integrated Traditional Chinese Medicine and western medicine on the disease of cystic hyperplasia of breast.[Method] The 214 cystic hyperplasia of breast cases were randomly divided into two groups.125 cases in the integrated Traditional Chinese Medicine and western medicine group(observed group).Control group(89 cases)were treated in common practiced western medicine.[Result]In observed group,70 cases fully recovered from illness,40 cases were excellent,6 cases were effective,9case were ineffective.Total effective rate was 92.8%.In control group,27 cases were fully recovered from illness,22 cases were excellent,20 cases were effective,9 cases were ineffective.Total effective rate was 77.4%.The differences between two groups were significant(P

Objective To investigate the clinical characteristics of general paresis of insane(GPI) and diagnostic value of laboratory and neuroimaging examinations.Methods The clinical data of 2 patients with GPI were analyzed retrospectively and the pertinent literatures were reviewed.Results The main clinical characteristics consisted of insidious onset,progressive dementia,mental disorder and epileptic seizure.These 2 patients were originally misdiagnosed.Both rapid plasma reagin test and treponema gelatin agglutination test in serum and cerebrospinal fluid were positive.Cranial MRI showed diffuse cerebral atrophy.Conclusions The clinical characteristics of GPI are varied and misdiagnosis rate is high at early stage of this disease.The diagnosis of GPI mainly depends on clinical characteristics,serum and cerebrospinal fluid examinations.

This paper introduces a new method which controls discharge energy accurately. It is achieved by calculating target voltage based on transthoracic impedance and accurately controlling charging voltage and discharge pulse width. A new defibrillator is designed and programmed using this method. The test results show that this method is valid and applicable to all kinds of external defibrillators.
