Objective To investigate the pathogen distribution and drug sensitivity in childhood bacillary dysentery,and to guide clinically the selection of reasonable antibiotics.Methods Bacterial drug susceptibility test was performed by standard Kirby-Bauer method.The results were interpreted according to NCCLS 2002.Results Of the 98 cases,there were two types of positive bacterial species:sh.flexneri(n = 77)and sh.sonnei(n = 21).Both sh.flexneri and sh.sonnei were sensitive to cefoperazone,eeftazidime,ceftriaxone,cefoperazone/sulbactam and fura- zolidone,and insensitive to ampicillin and co-trimoxazole.Conclusion sh.flexneri was the major pathogen of child- hood bacillary dysentery.The third generation cephalosporins were the first choice for shigella infections.

OBJECTIVEOvertraining is a serious problem in sports, assessed by comprehensive multi-index evaluation, but so far there is still no sensitive, specific monitoring indicator or simple evaluation method to evaluate it. This research established a method for detecting plasma cell free DNA (cfDNA) of rats by real time PCR and discuss edits significance: a new molecular marker of overtraining?

METHODSTwelve male SD rats were randomly divided into control group and overtraining group. The overtraining group rats were undertaken overtraining on a motor-driven treadmill for 5 weeks, while the control group rats kept quiescent. All the rats were drawn blood at pre-and after-5 weeks to detect plasma levels of cfDNA, testosterone (T) and corticosterone (Cort) as well as peroxidation/antioxidation parameters (T-AOC, MDA, SOD, GSH-Px) and creatin kinase (CK).

RESULTS(1) Plasma cfDNA of rat was detected specifically by our real time PCR. (2) Compared with control group rats, the plasma cfDNA of overtraining rats increased obviously (about 5.43 fold). (3) Plasma cfDNA was related to plasma T, Cort, T/C ratio and MDA (correlation coefficent were -0.729, 0.854, -0.655 and 0.720, respectively) rather than plasma T-AOC, GSH-Px, SOD and CK.

CONCLUSION(1) A real time PCR method was established successfully to determine plasma cfDNA of rat. (2) A remarkable raises of plasma levels of cfDNA were found in overtraining rats which were associated with T, Cort and T/C, suggested that plasma cfDNA might be a new molecular marker of overtraining. (3) The increase of plasma cfDNA of overtraining rat might correlate with enhanced oxidative stress induced by overtraining instead of muscle damage.

BACKGROUND: It has been reported tbat there are rich expressions of serotonin transporter (5-HTT) in the cortical and limbic regions related to emotion and behavior in cerebrum. Regulation of the intensity and persistence of serotonergic nerve response can change the serotonergic neurotransmission, meanwhile, 5-HTT is also an important target for selective serotonin reuptake inhibitors (SSRIs).OBJECTIVE: To observe whether there is a correlation of 5-HTT gene polymorphism with plasma level of 5-HT and the clinical response of SSRIs in the population of Nanjing area.DESIGN: A case-control observation.SETTING: Department of Psychiatry, Brain Hospital of Nanjing Medical University.PARTICIPANTS: Totally 132 inpatients with depression in the Department of Psychiatry, Brain Hospital of Nanjing Medical University and 100 volunteer healthy blood donors were taken as the observational subjects between January 2001 and December 2003.METHODS: The genotype was analyzed with polymerase chain reaction (PCR) polymorphism analysis in the patients with depression and healthy subjects; plasma level of 5-HT was analyzed with high performance liquid chromatography-electrical chemistry detector (HPLC-ECD); and the clinical response to the antidepressants were assessed with Hamilton depression rating scale (HAMD).MAIN OUTCOME MEASURES: The analytical results of 5-HTT genotype frequency and allele frequency in both groups, and the relationship between 5-HTT genotype and plasma level of 5-HT before and after SSRIs treatment were observed.RESULTS: Blood samples were collected from all the 132 patients with depression and 100 normal healthy subjects, and they all finished the scale test and entered the analysis of results. ① There were no significant differences between the depression group and normal control group in the 5-HTT gene genotype frequencies (LL: 24.2%, LS: 44.7%, SS31.1%; LL:29.0%, LS: 47.0%, SS: 24.0%, x2=1.405 8, P ＞ 0.05) and allelefrequencies (L:46.59%, S: 53.41%; L: 52.5%, S: 47.5%, x2=0.696 2, P ＞ 0.05). ② The total score of HAMD had significant differences before treatment among the depressive patients of different genotypes (F=6.48, P=0.002 1). After 4-week treatment of SSRIs antidepressants, the total score of HAMD was significantly decreased, and there was significant difference in the decrease of score (F=3.38, P= 0.037). ③ The plasma level of 5-HT had significant differences before treatment among the depressive patients of different genotypes (F=5.38,P= 0.005 7). After 4-week treatment of SSRIs antidepressants, the plasma level of 5-HT was increased, and the increased level was significantly different among different genotypes (F=23.55, P ＜ 0.01).CONCLUSION: The 5-HTT polymorphism may be not associated with the attack of depression, but with the severity of depression and the clinical responses of SSRIs in the population of Nanjing area, and the genotype in this area may become a reference index for the realization of individualized treatment in patients with depression.
