To report a boy with reflex seizures induced by micturition.He suffered from seizures during micturition for four yesrs.The clinical symptoms consisted of head backwards,limbs dithering,sometimes accompanying tumble.During the episodes of the seizure,his consciousness did not lose.Few seizures showed only eyes up-staring for several seconds.The livelong process of micturition was often interrupted by seizures for several times.When he finished or stoped micturition,the seizures did not occur again.His seizures could not be induced by free of micturition or other stimulative factors.The interictal EEGs showed that background asymmetry manifested as the lower amplitude and irregular rhythm in the left hemisphere,sharp or sharp and waves in right hemisphere,especially mid and back temporal.There also had sharp,spike,and spike and waves in many regions of double spheres in interictal EEGs.The other assistant check-ups were normal.while this disease was infrenquncy,it would be worthy to regard.

In the process of evolution, pathogenic Streptococcus pyogenes secretes an immunoglobulin G-degrading enzyme IdeS which can specifically cleave the hinge region of immunoglobulin G in order to escape the immune response against the host. On the one hand, IdeS can be used for IgG fingerprinting as a tool enzyme combined with mass spectrometry technology. On the other hand, IdeS can be used to treat the antibody-responsive diseases produced by autoimmunity as a therapeutic protein. In this study, the backbone of plasmid pCold was used to construct two expression vectors of recombinant protein IdeS, which were heterologously expressed in Escherichia coli Shuffle T7. After purification by affinity chromatography, the recombinant IdeS activity was detected and their activity differences between the two were compared. Among them, the yield of the recombinant IdeS containing the His6-tag at the N-terminus was 4 mg·L^-1, and the cleavage reaction with antibody IgG1 at 1∶200 (m/m) at 37 ℃ for 30 min could complete. However, the yield of the recombinant IdeS containing both the N-terminal His6 tag and the C-terminal silica affinity tag (silica bing peptide, SiBP) is 1.5 mg·L^-1, and the degradation reaction with antibody IgG1 at 1∶20 (m/m) at 37 ℃ for 30 min could reach the end. The C-terminal fusion peptide has a great influence on the yield and activity of IdeS, which is not conducive to subsequent application in drug development. Above all, the recombinant IdeS containing the His6-tag at the N-terminus expressed by this system has high activity and can fully meet the needs of antibody drug development and mapping analysis of IgG.

BACKGROUND: Aldosterone is an important pathogenic factor of left ventricular hypertrophy. There has been evidence that the extract of red sage root (a Chinese herb) can intervene the synthesis of aldosterone.OBJECTIVE: To investigate the effects of tanshinone Ⅱ A on expression of genes related to aldosterone synthesis in myocardium. DESIGN:A randomized and controlled trial. SETTING :Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology. MATERIALS:The experiment was performed at the laboratory of Emergency Department, Tongji Hospital Affiliated to Tongji Medical College,Huazhong University of Science and Technology from November 2002 to March 2004. Totally 20 male 12-week-old rats with spontaneous hypertension were randomly divided as hypertension group and tanshinone Ⅱ A group. METHODS:Rats in each group were injected tanshinone Ⅱ A or distilled water in the same volume respectively through caudal vein. After 12-week administration,the rats were put to death by decapitation, and the samples of myocardium were prepared. The expressions of CYP11B1mRNA and CYP11B2 mRNA, or myocardial genes related to aldosterone synthesis were examined with reverse transcriptase polymerase chain reaction (RTPCR) and referring to the amplification primers of glyceraldehydes 3-phosphate dehydrogenase (GAPDH) gene. MAIN OUTCOME MEASURES:The levels of CYP11B1 and CYP11B2 mRNA related to aldosterone synthesis in myocardium.RESULTS :Totally 20 rats were involved in the trial and all entered in the final result analysis without any loss of value. ① Quantitative analysis of expression of myocardial CYP11B1 and CYP11B2 genes in rats of two groups: Taking 100bp Plus Ladder as Marker,clear amplified strands could be seen at 440bp,461bp and 336bp sites,DNA sequencing proved they were the encoding gene segments of CYP11B1,YP11B2 and GAPDH. ②Qualitative analysis of expression of myocardial CYP11B1 and CYP11B2 genes in rats of two groups:The expressive levels of CYP11B1 and CYP1 1B2 mRNA contents in tanshinone Ⅱ A group were significantly lower than those in hypertension group (0.924±0.121 vs 1.343±0.132,P ＜ 0.05;1.017±0.119 vs 1.675±0.126,P 0.01). CONCLUSION:Tanshinone Ⅱ A could directly down-regulate the expression of CYP1 1B1 and CYP1 1B2 mRNA, the genes related to aldosterone syn thesis, so that it inhibited the biological synthesis of aldosterone in myocardinm, thus playing a role to resist hypertensive left ventricular hypertrophy.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.

METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.

RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).

CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.
