RESUMO
Stenotrophomonas maltophilia is a gram-negative bacillus which widely exists in natural and hospital environment, and it is also one of the common opportunistic pathogens in clinical settings. The virulence and pathogenicity of Stenotrophomonas maltophilia are weak, however, due to resistance to a variety of antibacterial drugs, it can cause bloodstream infections or pneumonia in immunocompromised or critically ill patients, leading to poor prognosis. Moreover, the inherent drug resistance and increasing acquired drug resistance may make the treatment of the first line antibiotics, like trimethoprim-sulfamethoxazole or quinolone ineffective. Therefore, it is important to understand the drug resistance mechanism and the main countermeasures for it. In this article, the research progress on drug resistance mechanism and treatment for Stenotrophomonas maltophilia are reviewed.
RESUMO
Objective To observe the clinical efficacy of umbilical compress with anti-cancer Xiaogu formula in managing malignant ascites. Methods A total of 56 patients with malignant ascites who met the inclusion criteria were randomized into 28 patients in the treatment group and 28 patients in the control group. The control group was treated with one type of diuretic, and the treatment group was given umbilical compress using Anti-Cancer Xiaogu formula and diuretics. Both groups were treated for 14 days. The changes of abdominal girth, 24 h urine volume, ascites efficacy, TCM syndrome scores, quality of life and adverse reactions were observed. Results The decrease in the maximum depth difference of the ascites in the treatment group was significantly greater than that of the control group (1.16 ± 1.29 vs. 0.00 ± 1.34, Z=-2.553). The difference was statistically significant (P<0.05). The decrease in abdominal girth in the treatment group was significantly larger than that in the control group (0.57 ± 0.55 vs. 2.61 ± 0.28, Z=-2.264). The difference was statistically significant (P<0.05). The in 24-hour urine volume in the treatment group after intervention (-800.18 ± 64.12 vs.-683.57 ± 55.38, Z=-1.770) was no statistically significant (P>0.05). The response rate in the treatment group was 92.9％ (26/28), while that of the control group was 89.3％ (25/28).treatment group was 71.4％, while that of the control group was 35.7％. The difference was statistically significant (P<0.05). The increase in KPS in the treatment group was significantly higher than that of the control group. The difference was statistically significant (P<0.05). Conclusions Anti-cancer Xiaogu umbilical cord combined with diuretic can reduce the degree of malignant ascites, alleviate clinical symptoms, improve quality of life and decrease the occurrence of adverse reactions when used concomitantly with diuretics in the management of malignant ascites.
RESUMO
Objective To observe the effect of inhalation budesonide(pulmicort) in the treatment of cough variant asthma and(CVA) its influence on serum cytokine.Methods 112 children with CVA were randomly divided into the atomization group and control group,each group 56 cases.The atomization group was given pulmicort inhalation therapy,and the control group was given oral long-acting β2 agonist treatment.After 3 months of treatment,the efficacy and serum cytokine levels were compared between the two groups.Results 3 months after the treatment,the effective rate of the atomization group was 91.07％,and significantly higher than that of the control group(75.00％ )( x2 ＝ 5.13,P ＜ 0.05 ) ; The serum interleukin-4,γ-interferon,IgE,eosinophil counts of the atomized group were significantly lower than those of control group ( t =2.10,2.34,27.63,3.13,all P ＜ 0.05 ).Conclusion The effect of inhalation pulmicort in the treatment of cough variant asthma is good,and has good safety.
RESUMO
Objective To explore the value of a novel non-peptide renin inhibitor aliskiren on hypertension patients,and analyze the change of bradykinin (BK) and high sensitive C-reactive protein (hs-CRP).MethodsEighty patients with mild to moderate hypertension were selected.Patients were randomized divided into ramipril group,aliskiren 75 mg/d group,aliskiren 150 mg/d group,aliskiren 300 mg/d group with 20 cases each by random digits table method and received the following types of intervention:ramipril 5 mg/d,aliskiren 75 mg/d,aliskiren 150 mg/d and aliskiren 300 mg/d.Enzyme-linked immunosorbent assay method was used for detecting hs-CRP.Radioimmunoassay method was used for detecting BK.Results After treatment,the levels of BK and hs-CRP in aliskiren 75 mg/d group,aliskiren 150 mg/d group and aliskiren 300 mg/d group [(5.06 ± 1.61),(5.05 ± 1.87),(5.27 ± 1.39) μg/L and (0.38 ± 0.11 ),(0.25 ± 0.05),(0.33 ± 0.11 ) mg/L] were significantly lower than those in ramipril group [ (7.12 ± 1.12) μ g/L,(0.49 ± 0.19) mg/L ] (P＜0.05 ).After treatment,the levels of SBP and DBP had no significant difference among the four groups (P＞0.05).Conclusion Aliskiren has a very good effect in decreasing blood pressure and does not cause the levels of BK and hs-CRP increasing.
