Chinese Journal of Primary Medicine and Pharmacy 2006;0(10):-
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: 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.
