ABSTRACT
Objective To investigate the efficacy of different adding times,treatment courses and doses of bifidobacterium and lactobacillus triple live bacteria in Helicobacter pylori (Hp) eradication.Methods A total of 280 patients Hp-infected were enrolled and randomly assigned to five groups.Group A received lansoprazole 30 mg,clarithromycin 500 mg and amoxicillin 1,000 mg bid for 14 days;group B received bifidobacterium and lactobacillus triple live bacteria 2,000 mg tid for 14 days followed by regimen of group A for another 14 days;group C1 received regimen of group A with addition of bifidobacterium and lactobacillus triple live bacteria 2,000 mg bid for 14 days;group C2:regimen of group A with addition of bifidobacterium and lactobacillus triple livc bacteria 2,000 mg tid for 14 days;and group D received regimen of group C2 followed by bifidobacterium and lactobacillus triple live bacteria 2,000 mg tid for another 14 days.4 weeks after end of treatment,Hp eradication was assessed by 13C-urea breath test.Adverse effects during the courses of treatment were recorded.Results A total of 252 (90.0％) patients completed the treatment.The completion rate in group A,B,C1,C2,and D were 78.6％ (44/56),92.9％ (52/56),87.5％ (49/56),96.4％ (54/56),and 94.6％ (53/56) respectively;the completion rate was significantly higher in group B,C2 and D than in group A (P ＜ 0.05),but there were no differences among groups B,C2 and D (P ＞ 0.05).According to intention-to-trcat (ITT) analysis,the eradication rate was 62.5％,80.4％,69.6％,85.7％,and 87.5％ in groups A,B,C1,C2,and D respectively.The eradication rate in groups B,C2 and D was significantly higher than that in group A (x2 =4.375,P =0.036;x2 =7.864,P =0.005;x2 =9.333,P =0.002),and the eradication rate was higher in group C2 than in group C1 (x2 =4.171,P =0.041),but there were no differences among groups B,C2 and D (P ＞0.05).As for per-protocol (PP) analysis,the eradication rate was 79.5％,86.5％,79.6％,88.9％ and 92.5％ in groups A,B,C1,C2,and D respectively,but no significant statistical differences were found among the five groups (P ＞ 0.05).Adverse effects included nausea,bloating,taste distortion,anorexia and constipation.The rate of adverse effects in groups A,B,C1,C2 and D was 67.9％ (38/56),26.8％ (15/56),35.7％ (20/56),21.4％ (12/56),and 17.9％ (10/56) respectively.The incidence rate was significantly lower in groups B,C2 and D than in group A (P ＜ 0.05),but no significant statistical differences were found among groups B,C2,and D (P ＞ 0.05).Conclusions The triple therapy combined with bifidobacterium and lactobacillus triple live bacteria can obviously decrease the adverse effects and improve patient compliance,thereby increasing the rate of Hp eradication.14-day therapy with probiotics is the best regimen.
ABSTRACT
Background:With the emergence of bacterial resistance,the efficacy of Helicobacter pylori(Hp)eradication therapy is decreasing in recent years. After the previous failed course of eradication therapy,the possibility of failure of re-eradication therapy is greater. Therefore,choosing the rescue therapy for Hp re-eradication is particularly important. Aims:To investigate the efficacy of levofloxacin-based triple therapy combined with probiotics as a rescue therapy for Hp re-eradication. Methods:A total of 192 patients with a previous failed course of standard triple therapy for Hp eradication were enrolled and randomly assigned into four groups. Group A:lansoprazole 30 mg + amoxicillin 1 000 mg + levofloxacin 200 mg bid for 14 days;group B:regimen of group A with the addition of bismuth potassium citrate 600 mg bid for 14 days;group C:bifidobacterium and lactobacillus triple live bacteria 2 000 mg tid for 14 days followed by regimen of group A for 14 days;group D:regimen of group A with the addition of bifidobacterium and lactobacillus triple live bacteria 2 000 mg tid for 14 days. At 4 weeks after end of treatment,Hp eradication was assessed by 13 C-urea breath test. Adverse effects during the course of treatment were recorded. Results:A total of 177(92. 2% )patients completed the study,the completion rates in group A,B,C and D were 87. 5%(42 / 48),83. 3%(40 / 48),97. 9%(47 / 48)and 100% , respectively;the completion rates in group C and D were significantly higher than those in group A and B(P 0. 05). Adverse effects included constipation,taste distortion,bloating and anorexia,the incidences of adverse effects in group A,B,C and D were 79. 2% ,95. 8% ,29. 2% and 22. 9% ,respectively;the incidences in group C and D were significantly lower than those in group A and B(P < 0. 05). Conclusions:Levofloxacin-based triple therapy combined with bifidobacterium and lactobacillus triple live bacteria can decrease the adverse effects of traditional triple and quadruple therapies and improve the patient compliance,thus increases the efficacy of rescue therapy for Hp re-eradication.
ABSTRACT
Bladder cancer stem cells may give the cause of the recurrence and metastasis of bladder cancer patients,and CD47 mediated the suppress of cytophagy maybe the important mechanism of cancerous cells' immunologic escape.It is practical to isolate bladder cancer stem cells and cure the bladder cancer by targeting the CD47.In this paper,the authors will address the progress of bladder cancer stem cells and CD47 as therapeutic target.
ABSTRACT
Objective There is a high occurrence rate of thalassaemia in Guangdong Province .Major and intermedia thalas-saemia bring severe burden for patients , families, and societies.This study aimed to reveal the economic burden of thalassaemia major and intermedia thalassaemia in Guangdong Province . Methods Eight areas of Guangdong Province were selected as the sampling ar-eas.Patients with major or intermedia thalassaemia were enrolled in the study .The patients′economic burden of this disease , inclu-ding direct economic burden , indirect economic burden and intangible economic burden was calcultated .The direct economic burden was estimated by outpatient fee , hospitalization expense , nutrition and transportation fees , indirect economic burden was evaluated u-sing disability adjusted life years ( DALY) combined with human capital , and intangible economic burden was calculated using method of willingness. Results Per average annual direct economic burden of 45 patients with major or intermedia thalassaemia was 43 058.66 yuan, per average annual indirect economic burden was 20 474.51 yuan, and per person intangible economic burden was 302 466.67 yuan. Conclusion Economic burden of major and intermedia thalassaemia is huge and most patients do not receive standardized treatment .More effective way should be taken to reduce the economic burden of thalassaemia and help the patients to re -ceive standardized treatment .

ABSTRACT
Objective To investigate the dynamic CT features of peripheral lung cancer (PLC) and pulmonary inflammatory pseudotumor(IPT).Methods 23 patients with PLC and 6 patients with IPT were undergone plain and dynamic enhanced CT scans (beginning at 30 s after the onset of injection,serial scan were obtained at 30 s intervals within 180 s) before surgery or administration of antibiotic.Results The average CT values of plain CT,CT enhanced attenuation at 30 s and 90 s were significantly different between PLC and IPT.There were no significant decline following peak enhancement in IPT but PLC within 180 s.Conclusion The comprehensive analysis of plain CT value,enhanced CT value at 30 s,and the decreasing rate after 90 s of administration of contrast material may be useful in differential diagnosis between PLC and IPT.
ABSTRACT
Objective To study the relationship between expression of p16 and tumor angiogenesis as well as value of CT enhancement in peripheral lung cancer. Methods twenty-three patients with peripheral lung cancer were examed with dynamic CT scan before surgery.The MVD、protein expression of VEGF and p16 were measured immunohistochemically on speciments of resected tumors.Results There were negative correlation tendency between expressions of p16 and VEGF,but the difference were no significant.During the course of delaying 30 s from injecting contrast dose,the relating coefficient was the highest between enhanced CT value and MVD,P=0.9364.The mean value of MVD and CT enhancement in the course of delaying 30 s in p16 negative expression group were higher than that in the group of p16 positive expression with no significant.Conclusion p16 negative expression may improve angiogenesis in peripheral lung cancer.
