Percutaneous transhepatic one-step biliary fistulation lithotomy combined with laparoscopic cholecystectomy for choledocholithiasis with gall stones / 中华普通外科杂志

Objective:To evaluate the clinical value of percutaneous transhepatic one-step biliary fistulation(PTOBF)lithotomy plus laparoscopic cholecystectomy(LC) in the treatment of choledocholithiasis combined with cholecystolithiasis.Methods:From Jul 2012 to Jun 2018, 44 patients with cholecystolithiasis and choledocholithiasis were treated by PTOBF + LC ( n=20) vs laparoscopic common bile duct exploration(LCBDE)+ LC( n=24). Results:The success rate of one-step operation in both groups was 100%.The average intra-operative hemorrhage and the average hospital stay after operation were higher in LCBDE+ LC group (all P<0.05). The post-operative complication rate of PTOBF lithotomy + LC group was 10.0% (2/20), recurrence rate of observation period was 10.0% (2/20), while that of LCBDE+ LC group was 8.3% (2/24), and 12.5% (3/24), the difference was not statistically significant (all P>0.05). Conclusion:PTOBF lithotomy combined with LC is a safe, effective and feasible minimally invasive method for the treatment of choledocholithiasis combined with gall stones.

Efficacy analysis of probiotics combined with standard therapy for eradication of Helicobacter pylori in children / 中华实用儿科临床杂志

Objective@#To evaluate the efficacy and safety of compound Lactobacillus acidophilus tablets or Saccharomyces boulardii Sachets combined with standard protocols for eradication of Helicobacter pylori(Hp) in children.@*Methods@#From March 2017 to March 2018, 120 children aged 3-10 years with Hp infection were admitted into the Department of Gastroenterology, Maternal and Child Health Hospital of Hubei Province, including 67 male and 53 female childen.They were divided into 3 groups (control group, compound Lactobacillus acidophilus group, Saccharomyces boulardii Sachets group) by the method of random number table.Control group was given Clarithromycin+ Amoxicillin+ Omeprazole, for 14 days orally; compound Lactobacillus acidophilus group and Saccharomyces boulardii Sachets group were given drugs respectively on the first day, 500 mg of compound Lactobacillus acidophilus was added, twice a day or 250 mg of Saccharomyces boulardii Sachets group, twice a day orally, for 14 days, respectively.The adverse reactions in children were observed during the treatment, andurea 13C breath test or the stool Hp antigen test was performed at least 4 weeks by the end of the treatment, and the children with negative results were judged to be eradicated successfully.The ulcer healing, Hp eradication rate and incidence of adverse reactions(nausesa, vomiting, loss of appetite, constipation, diarrhea) among the 3 groups were observed and the Hp eradication rate and the incidence of adverse reactions (nausea, vomiting, loss of appetite, constipation, diarrhea) were compared.@*Results@#The eradication rates in the control group, the compound Lactobacillus group, and Saccharomyces boulardii Sachets group were 80.0% (32/40 cases), 85.0% (34/40 cases), and 87.5% (35/40 cases), respectively, and the difference was not statistically significant (P=0.646); the ulcer healing rate was 100.0% of 101 Hp eradicators in 3 groups, and the ulcer healing rate of 19 cases without Hp eradicated was 48.15%, and there was a significant difference between them (χ2=51.30, P<0.01). However, there was no significant difference in the total effective rate among 3 groups (P>0.05). The overall incidence of adverse reactions in Saccharomyces boulardii Sachets group (P=0.021) and the incidence of diarrhea (P=0.002) and loss of appetite (P=0.021) was lower than that in the control group, and the differences were statistically significant.There was no significant difference in the incidence of adverse reactions between the two probiotic groups (P>0.05).@*Conclusions@#Both compound Lactobacillus acidophilus tablets and Saccharomyces boulardii Sachets group can reduce the overall incidence of adverse reactions and the incidence of diarrhea and appetite declines in children′s standard Hp eradication regimen without affecting Hp eradication rate.

Serial Expression of the Truncated Fragments of the Nucleocapsid Protein of CCHFV and Identification of the Epitope Region / 中国病毒学·英文版

The Crimean-congo hemorrhagic fever virus(CCHFV)is a geographically widespread fatal pathogen.Identification of the epitope regions of the virus is important for the diagnosis and epidemiological studies of CCHFV infections.In this study,expression vectors carrying series truncated fragments of the NP(nueleoeapsid protein)gene from the S fragment of CCHFV strain YL04057 were constructed.The recombinant proteins were expressed in E.coli and purified for detection.The antigenic of the truncated fragments of NP was detected with a polyclonai serum(rabbit)and 2 monoclonal(mAbs)(14B7 and 43E5)against CCHFV by Western-blot analyses.The results showed that the three expressed constructs,which all contained the region 235AA to 305AA could be detected by mAbs polyclonal serum.The results suggest that region 235-305 aa of NP is a highly antigenic region and is highly conserved in the NP protein.
