Objective To compare the diagnostic value of magnifying chromoendoscopy with probebased confocal laser endomicroscopy (pCLE) for differentiation of neoplastic from non-neoplastic colorectal polyps. Methods A total of 16 consecutive patients, who were diagnosed as having polyps with endoscopy between December 2009 and January 2010 at Nanfang Hospital, were included in this study. The pit pattern of the polyp was first determined with magnifying chromoendoscopy in all patients. Then, confocal images of the polyps were recorded and subsequently analyzed offline. Using pathological diagnosis as golden standard,the sensitivity and specificity of the two methods were compared. Results A total of 26 polyps from 16 patients were found. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of magnifying chromoendoscopy was 94. 1%, 77.8%, 88. 8%, 87. 5% and 88.4%, respectively,while those of pCLE were 100. 0%, 88. 8%, 94. 4% ,100. 0% and 96. 1%, respectively. There was no significant difference between pCLE and magnifying chromoendoscopy. Conclusion In differentiation between neoplastic and non-neoplastic colorectal lesions, pCLE shows higher sensitivity and specificity than does magnifying chromoendoscopy, although without significant difference. pCLE can be used as a new real time method to determine the property of colorectal polyps.

Objective:To evaluate the therapeutic efficacy of interposition urethroplasty on glandular hypospadias and severe penile curvature.Methods:A total of 9 cases of congenital glandular hypospadias and 2 cases of congenital severe penile curvature (>30°) treated with the interposition urethroplasty technique in the Shenzhen Children′s Hospital from November 2008 to December 2019 were retrospectively analyzed.The mean age of initial surgery was 40 (25-109) months.Two cases were surgically treated with one-staged interposition urethroplasty and the remaining were treated with two-staged interposition urethroplasty.They were followed up for 8 months to 12 years, including the penile morphology, urination, urethrocutaneous fistula, urethral stricture and uroflowmetry.Continuous variables were presented as ± s deviation, Student′s t-test was used for comparison between groups. Results:The median length of interposition urethra was 3.2 (2.2-4.2) cm.The cosmetic appearance of penis was good without residual chordee, urethral stricture or urethral diverticulum in all patients.Two cases had urethrocutaneous fistula(one-staged repair and two-staged repair were performed in one case respectively), which were successfully repaired by re-operation.The maximum of uroflowmetry in patients at 3 months [(8.3±1.0) mL/s] and 6 months [(6.7±1.9) mL/s] after surgery was significantly lower than that of children in healthy control group [(10.5±3.7) mL/s] ( t=3.221, 3.864, all P<0.05). However, there was no significant difference in 1-year maximum of uroflowmetry postoperatively between surgically treated patients [(10.5±3.7) mL/s] and healthy control group ( P>0.05). Conclusions:Interposition urethroplasty is an effective and safe treatment for glandular hypospadias and/or severe penile curvature in children.

OBJECTIVETo investigate the status quo and influence factors of self monitoring of blood glucose (SMBG) and self-efficacy of diabetes patients' that participated in community diabetes self management group.
METHODSBeijing, Shanghai, Chongqing, Jiangsu, Guangdong, and Zhejiang were selected as the study sites considering patients management experiences they had. 1 401 adult diabetes patients were recruited from communities via health records system screening, telephone notification, poster advertisement, letters invitation ways. Face to face questionnaire survey was applied to obtain patients' general information, diabetes history, diabetes knowledge awareness, SMBG, and self-efficacy information. Multiple linear regression was used to analyze the relationship between factors and self efficacy.
RESULTSThere were 519 male patients (37.0%) and 882 female patients (63.0%) with an average age of (64.9 ± 8.9) years old. Patients lived in city accounted for 48.0% (672/1 401) and rural patients accounted for 52.0% (729/1 401). Patients who conducted SMBG accounted for 79.9% (1 120/1 401) and 33.3% (446/1 401) patients conducted blood glucose monitoring 1-3 times per month. Rural patients, primary school educated, and new rural cooperative medical system (NCMS) covered patients had a higher proportion of never conducting SMBG which were 21.9% (160/729), 24.2% (160/662), and 26.3% (125/475) , respectively. Scores of self-efficacy was (69.24 ± 16.30) (hundred-mark system) with a relative lower score in monitoring of blood glucose (64.09 ± 20.08) and foot care (63.63 ± 21.40), as well as a highest score in taking medicine and insulin injections (76.10 ± 22.00). Multiple regression analysis on self-efficacy and its related factors show a negative correlation between patients' place of residence and self-efficacy (β' = -0.076) and a positive correlation between education and self-efficacy (β' = 0.114) as well as between diabetes knowledge awareness and self-efficacy (β' = 0.193)(t = -2.46, 3.71, 7.18, P < 0.05).
CONCLUSIONCommunity diabetes patients had a low self-efficacy and it was even lower among low economic and education degree patients. The worst parts were SMBG and foot care. Place of residence, education, and diabetes knowledge awareness are factors that influence patients' self efficacy.

Objective:To analyze the mortality level and trend of chronic and non-communicable diseases (NCDs) among elderly residents aged 65 and over in China from 2004 to 2018, and predict the age-standardized mortality rate of NCDs from 2019 to 2023.Methods:Data on resident death was collected from the National Mortality Surveillance data set and used to analyze the unstandardized mortality rates, age-standardized mortality rates, composition ratios and changing trends of NCDs among different genders, urban and rural areas, and geographical regions in China during 2004 to 2018. The age-standardized mortality rates were calculated based on the Year 2010 Population Census of China. The Joinpoint Regression Models were fitted by the weighted least squares method. The average annual percent change (AAPC) and its 95% confidence interval for the entire time period were calculated. Log-linear models were used to predict age-standardized mortality rates.Results:From 2004 to 2018, the age-standardized mortality rates of NCDs decreased from 4 697.05 per 100 000 to 3 555.35 per 100 000, with an average annual decline of 2.0% (95% CI: -2.7%- -1.3%). The age-standardized mortality rates among different genders, urban and rural areas, and regions showed a downward trend. The age-standardized mortality rates of eastern region (AAPC = -2.1%, 95% CI: -2.8%- -1.3%) and central region (AAPC = -2.8%, 95% CI: -3.4%- -2.1%) fell faster than that of western region (AAPC = -0.8%, 95% CI: -1.8%-0.2%). The proportion of deaths caused by NCDs increased from 89.82% to 91.41%, with an average annual increase of 0.1% (95% CI: 0.1%-0.2%). Expected to 2023, the age-standardized mortality rates for male (3 906.23 per 100 000) will be significantly higher than female's (2 708.43 per 100 000); and that in rural areas (3 283.20 per 100 000) will be approximately equal to that in urban areas (3 250.01 per 100 000); the gap of age-standardized mortality rate between the western (3 782.48 per 100 000), eastern (3 037.01 per 100 000), and central region (3 249.24 per 100 000) will be further increased. Conclusion:From 2004 to 2018, age-standardized mortality rates of NCDs of the elderly residents in China showed a downward trend, and the proportion of deaths of NCDs showed an upward trend. Male and the western region elderly residents should be the key population for prevention and control of chronic diseases in the future.

Objective:To investigate and analyse the current status of screening and management of diabetic kidney disease (DKD) in six provinces and cities in China.Methods:The qualitative research method of focus group interview was adopted, based on the semi-structured interview outline, the clinical medical and disease control personnel in Tianjin, Chongqing, Gansu, Hubei, Heilongjiang, and Guangdong were interviewed. The interview transcripts were analyzed using thematic analysis, and MAXQDA analysis software was used for data management and analysis.Results:A total of 6 interviews were conducted with 49 interviewees. Forty respondents (81.6%) claimed that DKD screening was critical; 53.1% think that it was not easy for patients to obtain DKD screening services; 40.8%, 26.5% and 14.3% of the people believed that the technology of DKD screening services was moderate, simple or very simple, respectively. Of the respondents,16.3% thought that the cost of DKD screening service was relatively expensive, while 83.7% thought that the cost was inexpensive; 75.5% of the respondents believed that the patients could receive early DKD screening service. The factors of fully implementing medical reform policies, changing concepts and actively serving patients, and integrating external resources in medical and health institutions at all levels and of all types were conducive to the development of DKD screening and management services. The lack of technology and personnel for DKD screening services at the grassroots level, the lack of trust in the service capabilities of grassroots medical institutions by patients, the low level of patient awareness, and the novel coronavirus infection epidemic had an adverse impact on the development of DKD screening and management services.Conclusion:The screening and management services for DKD are relatively limited in China, and there is a significant fragmentation in the management and care of diabetes and DKD.

Objective:To discuss the diagnostic methods, clinical features and treatment options of bronchogenic cysts.Methods:A total of 86 patients with bronchogenic cysts and 5 patients with esophageal cysts and esophageal cysts were selected from January 2011 to May 2020 in the Affiliated Tumor Hospital of Harbin Medical University. There were 37 males and 49 females with bronchogenic cysts, aged 23 to 70(49.27±10.70)years old. According to the location of the disease, the patients were divided into mediastinal type(65 cases, 75.6%); intrapulmonary type(21 cases, 24.4%); bronchogenic cyst originating from the esophagus(9 cases, 10.5%).Results:The preoperative diagnosis coincidence rate was 9.3% in 8 cases. The rate of thoracoscopic surgery(59.3% in 51 cases), compared with the indwelling time of thoracic drainage tube after thoracotomy[(3.80±1.25) days vs.(4.97±1.54)days, P<0.001] and hospital stay[(7.08±1.75) days vs.(9.60±2.58)days, P<0.001] significantly shortened. 65 cases(71.4%, 65/91) were successfully followed up, with a median follow-up time of 34(2-111) months, and no recurrence was found. Conclusion:Bronchial cysts have no characteristic clinical manifestations, and it is difficult to make a clear diagnosis before surgery. Chest MRI has a great advantage in the diagnosis of cysts. For most cases, thoracoscopic surgery can achieve better clinical treatment results and has minimally invasive advantages. It is difficult to distinguish between bronchogenic cysts that originated in the esophagus and esophageal cysts, and there is no significant difference in clinical characteristics.
