Chinese Journal of Postgraduates of Medicine 2016;39(9):802-805
Objective To investigate the clinical effect of flupentixol and melitracen tablets combined with macrogol 4000 powders on treatment of irritable bowel syndrome with constipation (IBS-C) in elderly patients. Methods Fifty paients aged from 65 to 95 years with IBS-C were randomly divided into 2 groups: control group (23 patients) and treatment group (27 patients). The patients in treatment group received flupentixol and melitracen tablets (1 tablets, once a day) combined with macrogol 4000 powders (1 bag/time, 2 times a day) , while the patients in control group received macrogol 4000 powders alone. The treatment period was 4 weeks. The curative effect, the scores of self-rating depression scale (SDS) and self-rating anxiety scale (SAS) and adverse reaction were compared between two groups. Results At the improvement of depressive symptoms, the effective rate in treatment group and control group was 88.9%(24/27) and 39.1%(9/23), and there was significant difference (P<0.01). At the improvement of anxiety symptoms, the effective rate in treatment group and control group was 74.1%(20/27) and 26.1%(6/23), and there was significant difference (P<0.01). The total effective rate in treatment group and control group was 88.9%(24/27) and 65.2%(15/24), and there was significant difference (P<0.05). Conclusions Flupentixol and melitracen tablets combined with macrogol 4000 powders on treatment of aged IBS-C patients have more distinguished therapeutic effect in improving constipation symptoms, stools times, anxiety and depression.

3.Effects of Candesartan on the Expression of Cerebral NAD(P) H Oxidase mRNA in Salt-loaded Stroke-Prone Spontaneously Hypertensive Rats
Chinese Journal of Hypertension 2007;0(03):-
Background Oxidative stress has been implicated in the pathogenesis of angiotensin Ⅱ(Ang Ⅱ)related hypertension.Superoxide anion,produced by NAD(P)H oxidase,plays important roles in hypertension and its complications.Ang Ⅱ infusion increases cerebral NAD(P)H oxidase activity,which is inhibited by angiotensin Ⅱ receptor blocker(ARB)candesartan and NAD(P)H oxidase inhibitor.However,the underlying mechanism of ARB in preventing hypertensive stroke is not elucidated clearly.Objective To investigate the effects of candesartan on the expression of cerebral NAD(P)H oxidase mRNA in salt-loaded stroke-prone spontaneously hypertensive rats(SHRsp).Methods Twelve-week-old salt-loaded SHRsp were treated with candesartan [1.0 mg/(kg?d)],trichlormethiazide [TCM,1.6 mg/(kg?d)] or vehicle(n=12 in each)for 2 weeks.Age-matched salt-loaded WKY rats were served as control(n=12).Blood pressure was measured every week.After two weeks,cerebrums were harvested and 24 h urine was collected.Urinary albumin was examined by ELISA.Cerebral cortex NAD(P)H oxidase subunits(p22phox,p47phox and gp91phox)mRNA expression were assayed by real-time PCR.Results The systolic blood pressure was increased significantly in salt-load SHRsp.Candesartan and TCM reduced SBP to the similar level.Urinary albumin excretion and cerebral cortex NAD(P)H oxidase subunits were markedly higher in salt-loaded SHRsp than those in salt-loaded WKY rats.Incidence of stroke was significantly reduced in candesartan treated group as compared with TCM treated SHRsp(P
4.Changes in the drug resistance of E.coli induced by fluoroquinolones in vitro
Journal of Medical Postgraduates 2003;0(06):-
Objective:The drug resistance of E.coli to fluoroquinolones is getting stronger in the recent years.This study aimed at the drug resistance of E.coli induced by fluoroquinolones in vitro,so as to provide a guidance for the rational use of antibiotics and effective control of nosocomial infections.Methods: Drug resistance was induced in vitro by a multi-step method in 10 strains of E.coli from clinical isolates with Ciprofloxacin,Levofloxacin and Gatifloxacin.The minimal inhibition concentration(MIC) of the E.coli was determined by the agar dilution method before and after the induction.Results: After in vitro induction,the E.coli acquired a high resistance(MIC ≥ 128 ?g/ml).And one drug could induce different degrees of resistance to the other two.Conclusion: The MIC of the E.coli induced by fluoroquinolones in vitro was increased by 8 to 8 205 folds compared with that before induction,which demonstrated a gradually developed resistance of E.coli strains to fluoroquinolones.

ve To assess the cytogenetic toxicological safety of fish raised in water containing effluent. Methods The mutagenecity of organic extracts of uncooked meat specimens of fish raised in fishpond water mixed with sewage water taken from South and North Sewer Drainage Canals of Tianjin was detected by mice bone marrow micronucleus test. Results The organic extracts of uncooked fish meat specimens showed positive result for all of the 3 observed groups of fish raised in water of fish ponds with sewage, and negative result for fish raised in clean fishpond water in micronucleus test. Conclusion The results indicated that some kinds of organic mutagenic compounds ex-isted in the uncooked meat of fish raised in fishpond water containing effluent, which might have some potentially hazardous effects on human health through the food chains.

Objective To study the mutagenicity of fish-raising water containing effluent. Methods The niuta-genieities of water samples from waste water canal, the fish-raising water(fish-pond water) treated by presedimenta-tion in oxidation tank were detected using micronucleus test of vicia faba root tip cells. The micronucleus test of peripheral red blood cells was carried out among fish raised in water containing effluent. The water samples and fish collected from reservoir as controls. Results The micronucleus test of vicia faba root tip cells showed that the micronucleus rates in treated fish-pond water and waste water were significantly higher than those of negative control group (distilled water) (P 0.05) . The frequencies of micronucleus in peripheral red blood cells of fish raised in treated fish-pond water were significantly higher than those of fish raised in reservior water (P

Objective To evaluate the mutagenicity of mercury, cadmium, arsenic, chromium(Ⅵ)and lead in water on Vicia faba root tip cells. Methods The micronucleus assay of Vicia faba root tip cells were conducted to determine micronucleus rate of Vicia faba root tip cells induced by mercury (0.000 5-1.0 mg/L), cadmium (0.005-1.0 mg/L), arsenic(0.05-2.0 mg/L), chromium (Ⅵ) (0.05-2.0 mg/L) and lead (0.05-3.0 mg/L ) ,and pollution indexes were calculated. Results When the concentration of mercury was ≥ 0.5 mg/L, cadmium ≥ 0.1 mg/L, arsenic ≥ 0.5 mg/L and chromium(Ⅵ)≥ 2.0 mg/L in the water, the micronucleus rate were significantly higher compared with the negative control group, respectively(P
