Chinese Journal of Digestive Endoscopy 2012;23(1):32-35
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.
2.Application of needle -based confocal laser endomicroscopy in diagnosis of pancreatic cystic lesions
Journal of Clinical Hepatology 2017;33(1):49-52
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 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.

Objective To evaluate the efficacy of nuvastatin on the high level of serum lipoprotein(a) [Lp(a)] and itsclinical significance in patients with type 2 diabetic nephropathy. Methods In this study, 104 patients with microalbu-winuric type 2 diebetic h?phropathy) were divided into two groups randomly: the flu vastatin. group (zomg per day P.O. )and the control group. The efficacy at 6 weeks' beatment was evaluated. The serum Lp(a) concentration and the activityof tissue-type plasminogen activator(tPA ) and plasminogen activator inhibitor(PAI) were measured by enzyme-linkedimmunosorbent assay and chromogenic substances assay respechtively in all of the patients. Results At the beginning. ser-um Lp(a ) level and PAI activity along with a low tPA activity were abnormally high in every patient. In addition, the levelof Ccr was unconventionally high. After 6 weeks,the level of serum Lp(a) and the activity of PAI and tPA were cowectedsignilicanily in the teated group compared with the other group(P

Members of the tripartite-motif (TRIM) protein family share a highly conserved domain architecture known as RBCC motif,which is composed of a RING finger domain,one or two B-box domains,a coiled-coil domain as well as diverse types of C-terminal regions.TRIM proteins can not only maintain the normal physiological functions of the body,but also regulate the development of various diseases.In the current review,we focus on recent advances in the structures of TRIM proteins and their functions in the development of viral infection,cancer and neurodegenerative disease.

BACKGROUND: There are many studies on the quality of life (QOL) of patients with breast cancer at home and abroad at present. But the effect of antidepressants on the QOL of depressive patients with breast cancer is not clear yet.OBJECTIVE: To investigate the effect of fluoxetine on the QOL of depressive patients with breast cancer.DESIGN: A self-controlled and observational comparative study of taking the patient as the subjects.SETTING: The research institute of medical psychology and psychiatric specialty in two universities and a psychiatric department in a city hospital.PARTICIPANTS: Sixty-three female post-operative patients with breast cancer hospitalized in the First Affiliated Hospital and Second Affiliated Hospital of China Medical University and Dalian Tumor Hospital, with an average age of (50 ± 9) years.INTERVENTIONS: Sity-three depressive patients with breast cancer were treated with fluoxetine for 8 weeks. Treatment emergent symptom scale (TESS) and relative laboratory examinations were used to evaluate the safety of fluoxetine to depression and anxiety of depressive patients with breast cancer. QOL of WHO scale was used to assess the QOL of the patients before and after administration.MAIN OUTCOME MEASURS:①Score of every index of QOL of WHO;②Side effects and adverse effects.RESULTS: The scores of physiology, psychology and independence in QOLafter 8 weeks' administration(16.30 ±2.17, 14.41 ± 1.85, 16. 90 ± 1.53)were significantly higher than those before grouping (13.61 ±2.46,12.98 ± 2.65, 13.65 ± 2.45) ( t = 6.52, P < 0.01; t = 2.41, P< 0.05; t= 8.93, P < 0.01 ). No obvious side effect was observed during administration.CONCLUSION: Fluoxetine can significantly improve the QOL of patients with breast cancer and there are fewer side effects during the treatment.
