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.

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.

BACKGROUND: Monoamine hypothesis has been demonstrated by researches. However, the correlation between the metabolite of plasma monoamine neurotransmitter and anti-depression treatment in patients with depression has less been reported.OBJECTIVE: To study the effect of different drugs on metabolite of plaama monoamine neurotransmitter, and the correlation between the metabolite of plasma monoamine neurotransmitter and anti-depression treatment in patients with depression.DESIGN: Case controlled study.SETTING: Neurological Department and Brain Institute of Nanjing Medical University.PARTICIPANTS: Forty patients with depression hospitalized in Nanjing Brain Hospital (depression group) were diagnosed with the second revised edition of China classification of mental diseases(CCMD-2) and the tenth edition of International classification of diseases. And the total score of Hanmilton rating scale for depression(HAMD) was more than 17. Healthy voluntary blood donators in the control group were from Nanjing Municipal Central Blood Station( n = 20).INTERVENTIONS: Antidepressant was used in the depression for 4 weeks: fluoxetine 20 mg per day; 5-serotonin selective reuptake inhibitor (SSRI) paroxetine 20 mg per day; venlafaxime 50- 100 mg per day;5-serotonin and morepinephrine selective reuptake inhibitor(SNRI) fluvoxamine 50-100 mg per day. High performance liquid chromatograpy(HPLC)was used to measure the level of metabolite of plasma monoamine neurotransmitter in patients with depression before and 42 week after treatment, and the HAMD was used to evaluate clinical effect of the patients.MAIN OUTCOME MEASURES: The levels of metabolites of plasma monoamine neurotransmitters in patients with depression: 5-hydroxyindoleace tic acid(5-HIAA), 3-methoxy-4-hydroxyphenylglycol(MHPG) and homovani llic acid(HVA) were measured before and 4th week after treatment.RESULTS: The levels of 5-HIAA, MHPG and HVA of the metabolites of plasma monoamine neurotransmitters in patients with depression before treatment [ (20.3±14.6), (124.8±103.6), (54.7±32.1) μg/L] were all lower than those in the normal control group[ (39.5±28.4), (334.5 ±107.3), (88.5±37.2) μg/L], with statistically significant differences (P＜0.05). After SSRI treatment, the 5-HIAA content[ (37.1±21.9)μg/L]was significantly increased as compared with that before treatment, whose difference indicated significant meaning ( P＜0.05), but the differences in MHPG and HVA had no significant meaning as compared with those before treatment(P＞0.05) . After SNRI treatment, 5-HIAA and MHPG contents [(35.4±25.2 ), (291.2±120.4) μg/L] both were significantly increased, which indicated significant difference as compared with those before treatment( P＜0.05); but HVA level had no significant changes.CONCLUSION:'The peripheral neurotransmitter metabolites in plasma can reflect their states in brain. The change of neurotransmitter metabolite in plasma can be regarded as an important reference index for the evaluation of depression.

Objective To evaluate the effects of stepwise and fine-grained dietary management on the diet control of liver cirrhosis patients complicated with gastrointestinal hemorrhage. Methods Eighty liver cirrhosis patients complicated with gastrointestinal hemorrhage were assigned to experimental group (41 cases) and control group(39 cases) by random digits table method. The patients in experimental group were treated with stepwise and fine-grained dietary management and the patients in control group were given conventional dietary treatments. The compliance diet, mastery of nutrition knowledge, malnutrition risk at admission, intake food, discharge and 2 months after discharge between two groups were monitored. The incidence of rebleeding was tracked after 1 year of discharge. Results The incidence of malnutrition risk in Child-Pugh class C was higher than that in Child-Pugh class B( Z=-4.3, P<0.05 ) . The incidence of malnutrition risk in patients with high education level was lower than that in patients with lower education( r=-0.453, P<0.05 ). The experimental group significantly outperformed control group in mastery of nutrition knowledge at discharge:80(70, 84) points vs. 52(42, 64) points, in compliance diet and malnutrition risk after 2 months after discharge:86(76, 91)%vs. 53(46,57)%, 1(1, 2) points vs. 2(1,3) points, the rebleeding rate in experimental group was significantly less than that in control group within 1 year after discharge 14.6%(6/41) vs. 35.9%(14/39), and the differences were statistically significant between two groups ( χ2 = 4.226- 51.232, all P < 0.05 ). Conclusions Stepwise and fine-grained dietary management can improve the mastery of nutrition knowledge, compliance diet and nutritional status, and reduce the occurrence of rebleeding, worth popularizing further in clinical care of liver cirrhosis patients complicated with gastrointestinal hemorrhage.

AIM:To investigate the role of high glucose in primary hepatocytes of mice fed with a high fat di-et.METHODS:Male C57BL/6J mice were fed a high fat (45%of calories) diet ad libitum for 6 weeks to induce hepatic steatosis.Primary hepatocytes were isolated from the mouse liver by the 2 step collagenase perfusion method .The cells were incubated in low glucose ( 5 mmol/L ) , low glucose plus mannitol ( 30 mmol/L ) , or high glucose ( 35 mmol/L ) DMEM medium for 12 h.The cell viability , apoptosis , mitochondrial membrane potential , and caspase enzymatic activities were measured.Furthermore, proteins related to the stress-sensitive signaling pathway of regulating high glucose-induced apoptosis in primary hepatocytes were determined by Western blotting .RESULTS:Incubation with 35 mmol/L glucose re-sulted in a significant decrease in cell viability and an increase in apoptosis , whereas mannitol had no significant effect on the cell viability or apoptosis .A progressive depolarization of the mitochondria , an increase in cytosol cytochrome C and a dramatic decrease in mitochondrial cytochrome C in high-glucose stressed hepatocytes were observed .The enzymatic activi-ties of caspase-9 and caspase-3, but not caspase-8, were significantly increased in high glucose-stressed hepatocytes ( P<0.05).High glucose treatment suppressed the expression of Bcl-2 and Bcl-xL, while it increased the expression of the pro-apoptotic factor Bax .CONCLUSION:High glucose stress reduces mitochondrial membrane potential , initiates mitochon-dria-mediated apoptotic pathways and promotes apoptosis of hepatocytes with steatosis .This may be an important pathologi-cal mechanism of hyperglycemia-induced progression of nonalcoholic fatty liver disease .
