BACKGROUND Moxifloxacin-containing triple therapy has been suggested as an alternative second-line therapy for Helicobacter pylori infection. AIMS To systematically review the efficacy and tolerance of moxifloxacin-containing triple therapy in second-line H. pylori eradication, and to conduct a meta-analysis of studies comparing this regimen with(More)
Mytichitin-A is an antimicrobial peptide isolated from the serum of Mytilus coruscus and is reported to inhibit bacterial growth as tested on several Gram-positive bacteria. To produce large quantity of Mytichitin-A to further investigate its biological activity, nucleotide sequence encoding a recombinant 6 × His-Mytichitin-A (rMytichitin-A) peptide was(More)
AIM To improve the prevention and treatment of senile patients with colorectal cancer by evaluating the importance of colonoscopy in clinical screening and follow-up. METHODS Clinical screening of colonoscopy was performed for 2196 patients aged 60-90 years old according to the protocol,and 1740 of them (79.2%) were followed-up. RESULTS Colorectal(More)
The aim of this study was to evaluate colonoscopy in the diagnosis and treatment of rectal carcinoid tumors with diameter <1 cm. Elevated lesions with normal mucosal appearance under colonoscopy were identified. Endoscopic ultrasound (EUS) was performed in 16 patients. Lesions diagnosed as rectal carcinoid tumors were resected by endoscopic mucosal(More)
AIM To study the diagnostic significance of K-ras gene mutations in fecal samples from elderly patients with large intestinal cancer. METHODS DNA was extracted in the fecal and tissue samples from 23 large intestinal cancer patients, 20 colonic adenomatoid polypus patients and 20 healthy subjects. The K-ras gene mutations at the first and second bases of(More)
In China, electric vehicles (EVs) are becoming increasing popular. With several years practical operation experiences, a lot of news reports reveal the existing electrical supplementary heating can dramatically impact the driving range of EVs under cold weather in north China. The high efficient electric heat pump (HP) system has become the research(More)
OBJECTIVE To observe the changes of proximal femoral geometry after femoral neck fracture treated with THA, analyze the existent of differences and their manifestation. METHODS All patients of femoral neck fracture (FNF) and osteonecrosis of femoral head (ONFH) were treated with THA by the same operating team from January to December of 2014, including 22(More)
The antimicrobial peptide PaDef was isolated from Mexican avocado fruit and was reported to inhibit the growth of Escherichia coli and Staphylococcus aureus in 2013. In this study, an N-terminal 6 × His tagged recombinant PaDef (rPaDef) with a molecular weight of 7.5 KDa, for the first time, was expressed as a secreted peptide in Pichia pastoris. The(More)
