Chinese Journal of Clinical and Experimental Pathology 2015;(5):514-517
Purpose To discuss the relationship between age of onset and the HPV types infection in cervical adenocarcinoma. Meth-ods This study included 120 specimens of cervical adenocarcinoma in Jiangxi Maternal and Child Health Hospital. The specimen blocks were sliced by sandwich method. DNA was amplified by SPF10-PCR method. DNA genotyping was used with LiPA method. All biopsy specimens had pathologic diagnosis. The HPV infection of cervical adenocarcinoma specimens was analyzed. Results 120 ade-nocarcinoma cases were included in this study. HPV positive rate was 77. 5% (93/120). HPV 18 was the most prevalent type, which took up 43. 01% (40/93) of the total HPV positive cases, as same as HPV 16, which took up 43. 01%(40/93) of the total HPV pos-itive cases. The average ages of HPV 16 and HPV 18 were 43. 41 and 41. 06 years old respectively, other HPV types were 46. 85 years old, which showed statistically difference (F=3. 58, P=0. 032). Conclusion HPV 18 and HPV 16 are two most prevalent HPV types in cervical adenocarcinoma. The cases of HPV 18 infection are younger than other HPV-types infection.

OBJECTIVE:To review the curative efficacy and safety of itopride vs. domperidone in the treatment of functional dyspepsia(FD). METHODS:Randomized controlled trails(RCTs)of itopride vs. domperidone in the treatment of FD were enrolled and retrieved from Cochrane Library,PubMed,EMBASE,SCI,CBM,CNKI,VIP and Wanfang Database. Other retrieval was carried out by hand. Methodological quality evaluation and meta-analysis of RCTs were carried out. RESULTS:Of total 18 RCTs enrolled,11 RCTs were graded B and 7 RCTs graded C. Itopride group were superior to domperidone group in respect of total response rate,the relief rate of nausea,abdominal distention,belching,vomiting,epigastric pain and sour regurgitation. There was no statistical significance. The incidence of ADR in itopride group was lower than in domperidone group. There was no statistical significance in difference between two groups. The relief rate of anorexia and early satiety in itopride group were superior to domperidone group. Statistical significance was noted in difference between two groups. CONCLUSION:Recent study shows itopride has better effect than domperidone on FD,which should be confirmed by high quality study.

Objective To study the value of lung window and soft tissue window in measuring colon diseases with experimental CTVC examination.Methods Twenty-four artificial polypoid diseases were placed with glue in a thoroughly cleaned porcine colon(overall length,150 era)that was distented with air and submerged in a water phantom and scanned 10 times on a 64-MSCT(GE Light speed)with identical scanning parameters.The data were reconstructed every 0.625 mm and reviewed using 2D images, navigation,MPR and 3D volume-rendered images on a GE AW 4.2 workstation.The maximum diameters of the artificial polypoids were measured by two radiologists with more than 10 years working experience in lung window(W = 1000,L =-700)and soft tissue window(W =400,L =40),respectively.The average value of maximum diameters of the artificial polypoids were measured for 10 times and were compared with the actual diameter.Results Twenty-four artificial polypoid diseases and their shape,size,loeation and relation of diseases with bowel wall were all showed excellently.The maximum diameter measured was close to the actual diameter.The average value was mostly less than actual diameter and a few of them more than the actual diameter.The maximum diameter measured in lung window was close to the actual diameter,and there was no difference between the two data sets(t =0.431,P =0.669).There was difference between the maximum diameter measured in soft tissue window and the virtual diameter(t = 2.691,P = 0.010). Conclusion In screening the colon diseases,CTVC is a good method of choice with no insult or less insult, and higher repeatability.The lung window should be chosen in measuring colon diseases in CTVC examination.

Objective To evaluate the techniques and application of 64-slice helical CT colonography in colonic lesions. Methods Thirty-eight patients (including 12 colonic carcinomas,10 polypi, 9 colon multiple scrobiculus, 2 multiple diverticula, 2 negative, 1 congenital bowel malrotaion,1 ulcerative colitis and tunica mucosa glandular organ hyperplasy,1 colocolic anastomosis of terminal ileum and sigmoid colon) underwent volume scanning using 64-slice helical CT after cleaning colon. Six types of reconstruction including CT virtual colonoscopy(CTVC), volume rendering(VR), multiple planar reconstruction(MPR), 360?sectional view, RaySum,and navigation were gained.CTVC appearances were compared with that of conventional colonoscopy(CC).Results In 12 colonic carcinomas and 10 polypi,the lesions’ morphology,number,size, were satisfactorily shown by CTVC. The lesions’ location,range,and 1 intestinal canal obviously stenosis were also exactly shown by RaySum.The relationship between tumor and environment, 3 liver or retroperitoneal lymph node metastasis were satisfactorily shown by MPR and 2D transection image. On 360?sectional view,the distance between tumor and anus was exactly measured and the result was in conformity to that of CC. Of the CTVC appearances,1 sigmoid carcinoma and 1 transverse colon polyp was in unconformity to that of CC;1 ulcerative colitis and descending colon carcinoma was diagnosed as ulcerative colitis and tunica mucosa glandular organ hyperplasy by pathology.Conclusion 64-slice helical CT is a valuable imaging technique for detecting colon diseases. CTVC can obtain more clinical information than CC combining MPR,RaySum and VR.
