Objective: To explore influence of coping style on sleep quality and blood pressure in community male population with high normal value blood pressure. Methods: The Pittsburgh sleep quality index (PSQI) and coping style questionnaire (CSQ) were used to assess 120 men with high normal blood pressure in community. With PSQI>7 scores as criterion for judging sleep quality disorders, the subjects were divided into sleep disorder group (n=51) and normal sleep group (n=69), and sleep disorder group received psychological intervention. Results: Sleep disorders existed in 42.5% male population with high normal blood pressure. Compared with normal sleep group, there was significant increase in PSQI [（6.43±2.59）scores vs. (8.33±3.14）scores] and diastolic blood pressure [(81.00±8.91) mmHg vs. (88.00±5.69) mmHg] and significant decrease in factor scores of “problem solving” [(0.76±0.21) scores vs. (0.61±0.18) scores] and “asking for help” [(0.52±0.26) scores vs. (0.41±0.11) scores] in sleep disorder group, P<0.05 all; Compared with before intervention there were significant increase in scores of “problem solving” [(0.61±0.18) scores vs. (0.71±0.12) scores]and “asking for help” [(0.41±0.11) scores vs. ( 0.51±0.13) scores]and significant decrease in PSQI score [(8.33±3.14) scores vs. (7.41±2.37) scores] and diastolic blood pressure [(88±5.69)mmHg vs. (80± 4.17)mmHg] after psychological intervention 12 weeks in sleep disorder group, P<0.05 all. Conclusion: Psychological intervention may improve sleep quality and reduce blood pressure in community male population with high normal value blood pressure.

Objective:To analyse the causes of early implantation failure and the therapeutic measures with re-implantation after the failures.Methods:6 cases of implantation failure including early infections,loosening and non-osteointegration were reviewed and trea-ted by re-implantation therapy,and the causes of failure were discussed and the effects of re-treatment were evaluated.Results:2 cases were found to be with infection of adjacent teeth after implantation and were treated by removal of the implant,socket curettage,root ca-nal therapy(RCT)and antibiotics followed by reimplantation.Implant loosening and non-osteointegration were observed in 4 cases, which were treated by the similar methods for the implant socket.Reimplantation was successful in all 6 cases followed-up for 1 -3 years.Conclusion:Preventive measure for implantation failure should include indication selection,control of infections in adjacent teeth and periodontosis,use of GBR technic and so on.Re-implantation following proper treatment of adjacent teeth and the socket of implant is effective for the treatment of implantation failure.

ObjectiveTo analyze the risk factors for false negative diagnosis of obscure gastrointestinal bleeding (OGIB) by capsule endoscopy.MethodsA total of 133 OGIB inpatients,104 in true positive group and 29 in false negativc group,were reviewed.The features of demography,diseases and capsule endoscopy were collected and then analyzed,which included 10 variables like age,sex,time of bleeding,diseases accompanied,type and location of the disease,hemoglobin concentration,transit time of CE,quality of CE pictures and type of purgative agents.All data were analyzed with t test,and all the enumeration data were analyzed with chi square test.Logistic regression was used to analyze the correlation between the factors and results of diagnosis.ResultsAge ( t =2.095,P =0.038 ),concentration of hemoglobin ( t =2.143,P=0.034),type (X2 =20.222,P ＜0.001) and location (X2 =33.732,P ＜0.001) of the diseases,image quality of the CE (X2 =9.219,P =0.002 ) and the type of purgative agents (X2 =6.999,P =0.024) were found to have statistical differences between the two groups.Chi-square and partition Chi-square test revealed the occurrence of civerticulosis and lesion location,i.e.lower ileum and ileumcecum,were of statistical difference between the two groups (X2 =22.233,P ＜ 0.001 and x2 =24.412,P ＜ 0.001 ).Univariate logistic regression showed diverticulosis ( OR =0.102,P ＜0.001 ),lower bowel diseases ( OR =0.110,P ＜0.001 ),poor quality of CE pictures ( OR =0.258,P =0.004 ) and the use of sodium phosphate agent ( OR =0.367,P =0.027) were risk factors for false negative diagnosis,while older age facilitated diagnosis ( OR =1.024,P =0.041 ).However,multivariate logistic regression showed no statistic significance in type of purgative agent ( P =0.05 ) or the concentration of hemoglobin ( P =0.394).Furthermore,elder age facilitated positive diagnosis ( OR =1.031,P =0.032),while diverticulosis ( OR =0.118,P =0.001 ),lower bowel diseases ( OR =0.145,P =0.001 ) and poor quality of CE pictures ( OR =0.245,P =0.016) were correlated with higher probability of false negative diagnosis.ConclusionAge,disease type,disease location and image quality exert great influence on CE diagnosis.Diverticulosis,lower location of the diseases and poor CE image quality are risk factors for false negative diagnosis.

Objective:To validate gender-related differences in patients with upper tract urothelial carcinoma (UTUC).Methods:We used a method of combination of SEER database analysis and validation in our center. We selected 2 125 men (57.8%) and 1 552 (42.2%) women who underwent radical nephroureterectomy (RNU) for UTUC between 1995 and 2015 within the surveillance, Epidemiology, and End Results registries (SEER). In male cases, the median age was 71(22-99)years old, median follow-up time was 53.0 (0-227) months, 902 (89.5%) cases were Caucasian, 1 384 cases (65.1%) were located in the renal pelvis, and 810(38.1%) cases were T 3-T 4. For female cases, the median age was 73.6(25-99)years old, median follow-up time was 53.1(0-226) months, 1 417(91.3%) cases were Caucasian, 1 043 cases (67.2%) were located in the renal pelvis, and 508 (32.7%) cases were T 3-T 4. The analysis of SEER database showed that female patients were older compared to male patients ( P=0.002), the proportion of T 3-T 4 was even lower ( P=0.028). There were no statistically significant differences in race, tumor location, and follow-up time between males and females (all P>0.05). We also enrolled 131 men (55.3%) and 106 women (44.7%) who underwent RNU for non-muscle invasive (T a/T is/T 1) UTUC between January 2000 and January 2015. These patients had no history of bladder cancer, UTUC and kidney transplantation. Preoperative cystoscopy was performed to confirm the absence of bladder tumor. The male group was (65.8±12.4)years old, with history of aristolochic acid medications in 7(5.3%) cases, 98 smoking cases (74.8%), and estimated glomerular filtration rate (eGFR) of (64.2±29.4)ml/(min·1.73 m 2). In the female group, mean age was (66.7±11.9)years, 14 (13.2%) cases had history of aristolochic acid medications, 16(15.1%) had history of smoking, eGFR (56.3±27.9) ml/(min·1.73m 2). Compared with female patients, male patients tended to had less aristolochic acids exposure (5.3% vs.13.2%, P<0.001), frequent smoking (74.8% vs. 15.1%, P<0.001) and better renal function ( P=0.036). The Kaplan-Meier test was used for time-to-event analysis. Univariate and multivariate logistic regression models were adopted to examine the effect of gender on the development of T 3-T 4 tumor. Univariate and multivariate Cox regression analyses were used to assess the roles of factors on overall survival (OS) in both SEER and cases in our center, and competing-risks regression model was used to assess the roles of factors on cancer-specific survival (CSS) in both SEER and cases in our center. Results:Multivariate logistic analysis showed that gendere represented an independent risk factor of T 3-T 4 UTUC development( OR=0.86, P=0.02). Kaplan-Meier analysis showed that better OS and CSS for females only existed in the non-muscle invasive stages(5-year OS rates were 80.4% vs.87.3%, χ 2=31.0, P<0.001; 5-year CSS rates were 82.6% vs.89.2%, χ 2=31.2, P<0.001). In multivariate competing-risks regression models, no statistically significant differences in survival were observed between males and females ( HR=0.83, P=0.115). For the patients in our center, there were also no statistically significant differences existed in the non-muscle invasive stage between two genders on OS and CSS ( HR=0.93, P=0.071; HR=0.87, P=0.064). Conclusions:Females were less likely to have advanced pathological T stage. The differences on OS and CSS between males and females only existed in non-muscle invasive stage. However, after accounting for gender related factors, gender no longer had effects on UTUC prognosis.

Objective To alleviate the pain of patients with lower extremity trauma at dressing change, reduce staffing and increase the comfort of the operator and patient during dressing changes with design of lower limb dressing change stent. Methods Lower limb dressing change stent was made by welding and assembling with stainless steel tubes. In the clinical study, a total of 56 patients were divided into experimental group ( using lower limb dressing change stent) and control group (not using lower limb dressing change stent), 28 cases respectively. Patients′comfort, self-evaluation of anxiety scale ( SAS) , visual analogue scale ( VAS) pain score were compared between two groups. Results 85. 7% of patients in experimental group and 32. 1% patients in control group gave very good, good and general answers during comfortable evaluation. 14. 3% patients in experimental group and 67.9% patients in control group considered that dressing changes were bad but tolerable or very bad. The difference between two groups was statistically significant ( Z=-3.98, P<0.05) . Self-evaluation of anxiety scale score ( SAS) on postoperative day 7 in experimental group and control group were ( 44. 36 ± 15. 94) and (53.50±15.37), the difference was statistically significant (t=-2.184, P<0.05). Visual analogue scale pain score (VAS) on postoperative day 2 and 5 in experimental group were (6.75±1.43) and (4.60± 1. 16) and lower than those in control group, the differences were statistically significant ( t=3. 90, 3. 28, P<0. 01) . Conclusions The lower limb dressing tent has advantages of simple structure, low cost, and could reduce the pain and psychological burden of patients, increase comfort during dressing changes and is worth popularization and application in clinical orthopedics.

Cox proportional hazards regression model (Cox model) is the most commonly used multivariate approach in time-to-event data analysis. A vital issue in fitting Cox model is choosing the appropriate time scale related to the occurrence of the outcome events. However, few domestic studies have focused on selecting and applying time scales for Cox model in the analysis of cohort study data. This study briefly introduced and compared several time scales in the reports from literature; and used data from the Shanghai Women's Health Study to illustrate the impact of different time scales on data analysis results, using the association between central obesity and the risk of liver cancer as an example. On this basis, several suggestions on selecting time scales in Cox model are proposed to provide a reference for the analysis of cohort study data.

Objectives:To analyze the status and temporal changes of disability-adjusted life year (DALY) for stomach and colorectal cancers among registered permanent residents in Changning District of Shanghai Municipality, and provide scientific basis for the prevention and treatment of stomach and colorectal cancers in this district.Methods:Using the cancer registration data of stomach and colorectal cancers from 2002 to 2019, we estimated the indices such as the DALYs, the DALY crude rates, the age-standardized DALY rates, etc. Then we used the Joinpoint regression model to calculate the average annual percent change (AAPC) and annual percent change (APC) to explore the temporal variations in different periods.Results:The DALYs of stomach and colorectal cancers in Changning District from 2002 to 2019 were 55 931 person years and 65 252 person years, respectively. The crude rates of DALY were 512.16/10 5 and 597.51/10 5, respectively. We observed a higher disease burden in men than in women, and the peak rate of DALY in stomach cancer was in the 75-79 years age group, while in colorectal cancer the rate was in the 85-years-or-older age group. Joinpoint regression analysis showed that from 2002 to 2019, the age-standardized DALY rate of stomach cancer showed a downward trend (AAPC=-3.86%, P＜0.05), while the trend of colorectal cancer was not statistically significant(AAPC=-0.08%, P＞0.05). However, the trends in the age-standardized DALY rates of colorectal cancer were different between males and females, with males showing an upward trend (AAPC=1.24%, P＜0.05) and females showing a downward trend (AAPC=-1.67%, P＜0.05). Conclusions:The DALY of stomach and colorectal cancers in Changning District of Shanghai showed a decreasing trend. Males and the middle-aged and elderly populations are still the key targets for disease prevention and control in this district.

Objective This study was to develop a"Spleen Deficiency Certificate Scale for County Residents"and test its reliability.It was then developed as an objective tool for Chinese medicine evidence and symptoms for the prevention and control of chronic diseases among county residents.Methods The scale was compiled based on the team's previous foundation.The reliability of the scale was evaluated using internal consistency reliability and split-half reliability,while its validity was evaluated using structural validity,content validity,calibration validity,and discriminant validity.Results The study included 213 adults from Lanxi,of whom 155 were tested for intestinal flora.Seven scale entries were identified:Fatigue,fear of cold,bland mouth,loss of appetite,diarrhea,weak bowel movements,and tooth-marked tongue.In the reliability test,Cronbach's alpha coefficient was 0.828 and McDonald's ω coefficient was 0.825.The"stomach pain"and"bloating"entries did not meet the inclusion requirements and were recommended to be deleted.The Spearman-Brown coefficient was 0.839.The exploratory factor analysis of the two common factors explained 61.6%of the cumulative variance.The calibration validity indicated that the ratio of salivary amylase activity before and after acid stimulation was 0.826±0.253 in the group with spleen deficiency.Significant differences(P<0.05)in the genera Dialister,Shigella,Leuconostoc,Photobacterium,Trabulsiella,and Parvimonas between the spleen deficiency group and the non-spleen deficiency group.Conclusion The Spleen Deficiency Scale for County Residents demonstrates good reliability and validity.
