Objective To investigate the prevalence of cytotoxin associated gene(cagA)and vacuolating cytotoxin gene(vacA)subtypes of Helicobacter pylori(H.pylori)in patients with upper gastrointestinal disease in Shijiazhuang area,and to assess the relationship between cagA,vacA subtypes and H.pylori related gastrointestinal disease.Methods Totally 55 H.pylori strains were isolated from patients with chronic gastrointestinal disease in Shijiazhuang area.Bacterial DNA from all these strains was extractedThe prevalence and genetic diversity in cagA 3′ region,vacA signal sequence and middle-region alleles were studied by the technique of polymerase chain reaction(PCR).Results In Shijiazhuang area,H.pylori cagA positive rate was 89.1%(49/55);cagA positive rate was not significant ly different between chronic gastritis and peptic ulcer(?~2=0.376,P=0.540).There were three vacA subtypes,including s1a/ m2 90.4%(47/52),s1a/ m1b-m2 5.8%(3/52)and s1a/ m1b 3.8%(2/52).The vacA s1a/m2 subtype showed no significant difference between chronic gastritis and peptic ulcer(?~2=0,P=1.000).Conclusion cagA~+and vacA s1a/m2 subtype of H.pylori are predominant in patients with upper gastrointestinal disease in Shijiazhuang area.There is no relationship between cagA,vacA subtypes and H.pylori related gastrointestinal disease.

Objective To analyze the susceptible range and antibiotic resistance of clinical isolates of Helicobacter pylori(H.pylori) in Shijiazhuang area.Methods (1)H.pylori strains:55.(2)Drugs:Metronidazole,Ornidazole,Azithrumyein,Clarithromycin,Amoxicillin,Tetracycline and Furazolidone.(3)Sensitive test:filter paper agar diffusion method.Results The antibiotic resistance rate of Metronidazole,Ornidazole,Azithrumyein,Clarithromycin,Amoxicillin,Tetracycline and Furazolidone was 92.73%,85.45%,45.45%,9.09%,0,0,0,respectively.Conclusion The antibiotic resistance rate of H.pylori from Shijiazhuang area to Metronidazole,Ornidazole and Azithrumyein are very high,and the resistant strains to Clarithromycin has been found.There are no resistant strains to Amoxicillin,Tetracycline and Furazolidone.

OBJECTIVE: To investigate effect and safty evaluation of stellate ganglion catheter retention with discontinuous block on sudden deafness. METHOD: One hundred and twenty-six patiens with sudden monaural deafness were randomly divided into Catheterp and block and control groups with 42 cases in each group. All patients' throats were given conventional blood activating drugs, hormone and hyperbaric oxygen therapy. stellate ganglion puncture retained catheter were administrated to the patients in catheter group followed by ropivacaine block 1 times/day, block group stellate ganglion puncture and ropivacaine block 1 times/day. The patients in control group were only received routine comprehensive treatment. Patients in both catheter group and block groups were treated by hyperbaric oxygen therapy after the block treatment. Curative effects of three groups were observed. The patients' satisfaction, heart rate, the chages of blood pressure before and after the block, detachment of tubes, and adverse drug reaction were recorded. RESULT: The effect of the treatment in both catheter group, block group was better than in control group (85.7%, 37 cases); 83.3%, 35 cases) vs 64.3%, 27 cases, P < 0.05). The satisfactory rate in the patients in catheter group was significantly higher than block group (83.3%, 35 cases vs 61.9%, 26 cases, P < 0.05). The heart rate and the blood pressure before and 5 minutes after catheterization in catheter group and block groupwere changed obviously. Moreover, no adverse drug reaction and detachment of tubes were observed. CONCLUSION It is a safe and effective administration of stellate ganglion catheter retention with interrupted ropivacaine block.
