Objective To compare the clearing effect between combination use of mosapride and polyethylene glycol (PEG) and polyethylene glycol only for colonoscopy preparation of patients with constipation caused by functional diseases.Methods A total of 212 adult patients who underwent colonoscopy examination were recruited to this randomized single blinded controlled study.Patients in control group received 3 liters of PEG only,whereas patients of experimental group received 10mg mosapride 30min before 3liter PEG.The patients were surveyed for the tendency of constipation.Experimental variables including time of first defecation and completion of bowel cleansing,defecation frequency,and degree of discomfort during colonoscopy preparation were recorded.Results The times of first defecation and completion of bowel cleansing of experimental group were shorter than those of control group ( P ＜ 0.05 ),but there were no significant differences in defecation frequency,the degree of discomfort and the bowel cleansing quality between 2 groups ( P ＞ 0.05 ).The percentages of patients with constipation in control and experimental groups were 26.61％ and 26.67％,respectively.The defecation frequency and the degree of discomfort of constipative patients were similar in both groups ( P ＞ 0.05 ).The time of first defecation and time of completion of bowel cleansing of constipative patients in experimental group were shorter than those in control group ( P ＜ 0.05 ).The bowel cleansing quality of constipative patients in experimental group was better than that of control group ( P ＜ 0.05 ).There was no difference in defecation frequency and adverse reaction between 2 groups (P ＜ 0.05).Conclusion Combination of mosapride and PEG for colonoscopy preparations of patients with functional constipation tends to shorten times of first defecation and completion of bowel cleansing,and to increase the bowel cleansing quality.

At present,the diagnosis of gastric cancer and precancerous changes mainly depends on the histological examination of biopsy samples.Confocal laser endomicroscopy could enable realtime observation of tissue,cellular,and subcellular structure of gastrointestinal tract,and differentiate normal,hyperplastic,and neoplastic mucosa.Confocal laser endomicroscopy has shown the superiority and value in in vivo diagnosis of gastric cancer and precancerous changes, including atrophic gastritis,intestinal metaplasia,and intraepithelial neoplasia,et al.This article reviewed the advances in studies of the diagnosis of gastric cancer and precancerous changes by confocal laser endomicroscopy.

Pancreatic cystic lesions (PCLs)have various pathological types,extremely different biological behaviors,and different progno-sis.Current diagnosis of PCLs mainly depends on a comprehensive analysis of the patient's medical history,clinical manifestations,imaging examinations,serological examinations,fine needle aspiration biopsy,and cytological examination of cyst fluid.Needle -based confocal la-ser endomicroscopy (nCLE)is a novel method of microscopic endoscopy and is compatible with 19 -gauge puncture needle.Under the guid-ance of endoscopic ultrasound,nCLE can achieve real -time in vivo imaging of the cellular and subcellular structures of diseased tissues and thus helps with the accurate diagnosis of PCLs.This article reviews the application of nCLE in the diagnosis of PCLs.

【Objective】In-vitro antibacterial activity of the combination of Herba Violae(HV)and Herba Taraxaci(HT)in different proportions was compared and analyzed for the optimization of the combination proportion of Herba Violae and Herba Taraxaci and the influencing factors.【Methods】The minimum inhibitory concentration(MIC)of the combination of HV and HT was determined by agar double dilution method and the minimum bactericidal concentration(MBC)by broth dilution method,and bactericidal curve was traced.Meanwhile,the resistance of the combination of HV and HT induced by sub-inhibitory concentration was analyzed,and the influencing factors of in-vitro antibacterial activity were investigated.【Results】The combination of HV and HT in the proportion of 1∶4 had a better antibacterial activity on four kinds of gram-positive bacteria and on four kinds of gramnegative bacteria,and exerted an bactericidal effect on Escherichia coli and Klebsiella Pneumoniae(both MBC_(50)/MIC_(50) and MBC_(90)/MIC_(90) being 2).The bactericidal curve showed that 2?Log cfu/mL bacteria strain could be killed by the combination of the proportion being 1∶4 at 8~(th) hour,the effect being superior to that of other two combinations.Inoculation dosage,serum amount and pH value had no effect on in-vitro antibacterial activity.【Conclusion】The combination of HV and HT in the proportion of 1∶4 has a better antibacterial activity.

Objective To investigate the expression of human telomerase RNA component (hTERC)gene in cervical scraping samples, and the relationship between hTERC gene and cervical lesions. Methods The fluorescent in situ hybridization (FISH) was used to detect the expression of hTERC oncogene in cervical scraping samples in 100 cases, including 76 cases with cervical intraepithelial neoplasia, meanwhile, high risk human papillomavirus (HR-HPV) were detected by Hybrid Capture 2 (HC2) . The other 24 cases were negative for intraepithelial lesion (NILM). Results The positive expression rates of the hTERC gene in NILM,ASCUS, ASC-H, LSIL, HSIL and cervical cancer were 0, 32.25 %, 75.00 %, 35.71 %, 81.81 % and 100.00 % respectively. hTERC gene positive expression in normal group was less significantly than that in abnormal groups (P <0.05). There was a significantly difference between HSIL and ASCUS, LSIL (x2 = 6.1736, x2 =5.0004, P <0.05). The positive expression rates of the HR-HPV in ASCUS, ASC-H, LSIL and HSIL or higher lesions were 54.80 %, 75.00 %, 60.70 %, 90.90 % and 100.00 % respectively. HR-HPV positive expression in HSIL or higher lesions were more significantly than that in ASCUS group (x2=4.1767, P<0.05). Conclusion The overexpression of hTERC gene may play an important role in cervical carcinogenesis, therefore it can be used as a better tumor marker for prospective in early cervical cancer progresses.
