Objective To investigate the status of mental health and related factors in cervical cancer patients received radiotherapy and chemotherapy,and to implement individualized nursing intervention.Methods 60 cervical cancer patients with radiation and chemotherapy were enrolled in this study.The depression self rating scale(SDS),anxiety self-assessment scale(SAS) were evaluated,and the influence factors of self-designed questionnaires were investigated.During the same period,60 healthy women of 4 regions in Shantou were selected as control group.The SDS and SAS were compared in two groups.And combined with the influencing factors of the investigation group after the implementation of nursing intervention 7 d psychological assessment again.Results Cervical cancer patients with radiotherapy and chemotherapy,the SDS and SAS scores were (56.1±7.7)points,(45.2±7.5)points,which were significantly higher than those of healthy women [(45.0±6.3)points,(39.2±6.5)points,t=8.142,4.588,all P<0.01].After 7 days of nursing intervention,the SDS and SAS scores in cervical cancer patients decreased significantly[SDS(49.5±6.8)points,SAS(42.7±6.2)points,P<0.05],and the influence factors of patients' mental health were worry about the hospitalization expenses,do not understand the disease related knowledge,fear,the influence of family and society,and worry about the side effects of treatment on the prognosis of disease(88%,80%,80%,75%,68.3%,65%).Conclusion Cervical cancer patients received radiotherapy and chemotherapy have poor mental health status,in the treatment of diseases at the same time,the nursing staff should give psychological counseling and support,improve the patients' anxiety and depression,promote rehabilitation.

AIM:To investigate the expression of C/EBP homologous protein (CHOP) and its correlation with proliferative/apoptotic ratio (PAR) in colorectal adenoma-carcinoma sequence under the same genetic background .ME-THODS:Four kinds of tissue samples under the same genetic background from 23 patients, including normal colorectal tissue, adenoma with low-grade intraepithelial neoplasia , adenoma with high-grade intraepithelial neoplasia and colorectal adenocarcinoma samples , were collected .TUNEL method and Ki-67 immunohistochemistry were applied to determine the PAR.The expression of CHOP was detected by immunohistochemistry SABC method .RESULTS: ( 1 ) Under the same genetic background , the level of CHOP expression is significantly higher in colorectal adenocarcinoma than that in the ade -noma with high-grade intraepithelial neoplasia , the adenoma with low-grade intraepithelial neoplasia and the normal muco-sa.The level of CHOP expression was significantly higher in the adenoma with high -grade intraepithelial neoplasia than that in the adenoma with low-grade intraepithelial neoplasia and the normal mucosa .The level of CHOP expression was signifi-cantly higher in the adenoma with low-grade intraepithelial neoplasia than that in normal mucosa .(2) Under the same ge-netic background , PAR was significantly higher in the colorectal adenocarcinoma than that in the adenoma with high -grade intraepithelial neoplasia , the adenoma with low-grade intraepithelial neoplasia and the normal mucosa .PAR was significant-ly higher in the adenoma with high-grade intraepithelial neoplasia than that in the adenoma with low-grade intraepithelial neoplasia and the normal mucosa .PAR was significantly higher in the adenoma with low-grade intraepithelial neoplasia than that in the normal mucosa.(3) CHOP levels were positively correlated with PAR in the adenoma with low-grade intraepi-thelial neoplasia , adenoma with high-grade intraepithelial neoplasia and colorectal adenocarcinoma .CONCLUSION:CHOP expression and PAR continuously increased and positively correlated along the adenoma -carcinoma sequence , indica-ting that endoplasmic reticulum stress mediates the carcinogenesis of colorectal adenomas .

Objective To investigate the endoscopic prevalence of erosive esophagitis (EE) among 13 hospitals in Guangdong province of China. Methods Retrospectively reviewed all the cases (63459 cases) that received oesophagogastrodeuodenoscopy in 13 main hospitals in Guangdong province of China in 2003. Los Angeles criteria for classification of erosive esophagitis were employed as the basis of analysis. Results One thousand two hundreds and sixty-three patients (age range 3-90yr, mean 50. 2 ?17. 1 ) were found to have EE. The overall prevalence of EE was 1. 99% (1263/63459). The prevalence of EE in A, B, C, and D grade were 0. 94% , 0. 69% , 0. 21% and 0. 14% respectively. Age correlated positively on endoscopic grading of EE (F=22. 932, P

Objective Comparing the efficacy of endoscopic balloon dilatation and endoscopic stricteroto-my for postoperative anastomotic stenosis of colorectal cancer. Methods Retrospectively analyzed the clinical data of patients with postoperative anastomotic stenosis of colorectal cancer that underwent anastomotic dilatation from 2013 to 2016,and analyzed the anastomotic stenosis before and after treatment,and compared the efficacy of the two groups of dilatation methods. Results There was no statistically significant difference between the two groups in baseline characteristics. Balloon dilatation was effective in 3 cases(23.1%),ineffective in 10 cases(76.9%). 7 cases(63.6%)were effective in the stricterotomy group,4 cases(36.4%)were ineffective,the difference was statistically significant(P=0.045).Two groups of patients were not bleeding after surgery,infection and perfora-tion and other complications. Conclusion Endoscopic stricterotomy of postoperative anastomotic stenosis of colorectal cancer is more effective than conventional endoscopic balloon dilatation

At present, there are many problems in the nail-fold microcirculation detection devices, such as huge structure, inconvenience to carry. In addition, due to the patient's body shaking, the video is difficult to keep stable in collecting with the device, which brings great difficulties to the doctor's observation. We develop a small image acquisition device for nail-fold microcirculation based on the principle of SDF imaging principle and liquid lenses technology. An annular lighting device is fixed in front of the optical system, and the overall design of the system is based on the characteristics of human fingers. The device is small, easy to carry and conform to the fingertips. It can focus quickly through a controller. It can also achieve high quality images of the nail-fold microcirculation. This study can promote the usage of nail-fold microcirculation device at the bedside. It's an efficient tool for medical workers to observe the microcirculation of patients.

OBJECTIVETo investigate the safety, feasibility, clinical value, indication, and distribution of diagnostic diseases in different age groups of colonoscopy in pediatric patients.

METHODSA retrospective analysis was performed on the data of pediatric patients receiving colonoscopy from April 2013 to June 2016 at The Sixth Affiliated Hospital of Sun Yat-sen University. Pediatric patients were divided into 0-6 years group (n=57) and 7-14 years group (n=172). Indication for colonoscopy, detective events and diagnostic diseases distribution were compared between two groups.

RESULTSA total of 229 pediatric patients (male 157 and female 72) were divided into 0-6 years group (57/229, 24.9%) and 7-14 years group(172/229, 75.1%). The main Indications for colonoscopy included abdominal pain (81/229, 35.4%), hematochezia (64/229, 27.9%), crissum abscess or fistula (40/229, 17.5%). Hematochezia was the most common complaint in 0-6 years group (40/57, 70.2%), while abdominal pain in 7-14 years group (74/172, 43.0%). Completion rate between 0-6 years group and 7-14 years group was not significantly different (87.72% vs. 85.47%, χ=0.181, P=0.671). Only one pediatric patient (1/229, 0.4%) developed transient oxygen desaturation and recovered quickly after oxygen supply and aspiration of sputum. No serious complications such as bleeding, perforation or death occurred. Including 45 pediatric patients in 0-6 years group and 102 pediatric patients in 7-14 years group, a total of 147 pediatric patients (147/229, 64.2%) were found to have colorectal lesions. Inflammatory bowel disease (57/147, 38.8%), colonic polyps (40/147, 27.2%) and other intestinal inflammation (39/147, 26.5%) were the main findings. The most frequent diagnosis in 0-6 years group was colonic polyps (28/57, 49.1%), among them, 25 pediatric patients (25/28, 89.3%) were with the complaint of hematochezia. The most frequent diagnosis in 7-14 years group was Inflammatory bowel disease (54/172, 31.4%), among them, 29 pediatric patients (29/54, 53.7%) were with the complaint of abdominal pain.

CONCLUSIONSPediatric colonoscopy is safe and effective. Hematochezia and abdominal pain are the most common complaints in 0-6 years group and 7-14 years group respectively. Colonic polyps and inflammatory bowel disease are the most frequent diagnosis in 0-6 years group and 7-14 years group respectively.
