[Abstract ] Objective At present, few studies are reported on procalciton (PCT) and endotoxin (ET) in the diagnosis of urosepsis after percutaneous nephrolithotomy ( PCNL) .The purpose of this study was to investigate the clinical value of the detection of serum procalcitonin and endotoxin in the early diagnosis of urosepsis after PCNL . Methods We retrospectively analyzed the clinical data about 427 cases of upper urinary tract stones treated by PCNL , among which urosepsis developed postoperatively in 49 ( the urosepsis group ) and the other 378 non-urosepsis cases served as controls .At 1 day and 2 hours before PCNL , we detected the levels of serum ET and PCT and analyzed the PCT and ET levels and the results of combined detection in the two groups of patients using the ROC curve. Results At 2 hours before surgery , both the levels of PCT and ET were significantly higher in the urosepsis group than in the non-urosepsis controls ([ 5.18 ±4.43 ] vs [ 1.38 ±1.01 ] ng/mL, P<0.01;[50.91 ±35.45] vs [17.86 ±10.78] pg/mL, P<0.01).ROC curve analyses manifested that the areas under the curve (AUC) of PCT and ET were 0.841 ±0.038 and 0.786 ± 0.043, their sensitivities were 79.6%and 71.4%, and their specificities were 78.0%and 70.1%, respectively.The combined de-tection showed the AUC, sensitivity, and specificity to be 0.915 ±0.029, 85.7%, and 86.5%, respectively, all significantly higher than either PCT or ET detection alone (P<0.01). Conclusion The combined detection of PCT and ET can significantly increase the sensitivity and specificity of early diagnosis of urosepsis after PCNL and is superior to either PCT or ET detection alone .

Objective To study the clinical outcome of endoscopic vessel harvesting system (EVH) for the treatment of lower limbs varicose veins.Methods Patients (n =41) with varicose veins admitted from Jan 2011 to May 2013 were randomly divided into EVH group (n =20) and stripping group (n =21).Indexes as postoperative VAPS (48 hours and 1 week),subcutaneous ecchymosis (1 week),hematoma(1 week),skin numbness (1 week),CEAP classification (3 months),surgery effect and satisfaction scores(3 months) were compared between the two groups.Results 48 hours and 1 week VAPS was lower in EVH group(P ＜0.01).After EVH there was less subcutaneous ecchymosis (1 week),hematoma(1 week) and skin numbness (1 week) (all P ＜ 0.01).Postoperative CEAP classification improved significantly in both groups (P ＜ 0.01),while surgery effect and satisfaction scores (3 months) were better in EVH group (P ＜ 0.05).Conclusions EVH is a safe and minimally invasive technique in treatment of varicose veins of the lower limbs.

Objective To investigate the effect of all trans-retinoic acid (ATRA) combining with Interferon α-2a on bladder tumor and the possible mechanisms. Methods Fifty female Wistar rats with bladder tumor were established and separated into 4 groups randomly that are DMSO group (A), IFN-α-2a group(B), ATRA group(C) and ATRA+IFN-α-2a group(D). Then each group was treated by drugs indicated. Finally, the weight of bladder, the stage and grade of tumor, the apoptosis and proliferation index of tumor were determined to estimate the effect of ATRA+IFN-α-2a. Results The body weights in group D are the highest and the bladder weights in group D are the lowest. The stages and grades of tumor in group D were statistically decreased compared with those in the other 3 groups. Accordingly, the apoptosis of cancer cells in group D was enhanced, whereas the proliferation index in group D was decreased significandy. Conclusion The effect of ATRA combined with Interferonα-2a on the bladder tumor is better than that of monotherapy.

Objective To study the clinical use of the ulnar-basilic arteriovenous fistula as a long-term vascular access in patients with hemodialysis.Methods The clinical data of 36 patients with 1-year follow-up who had a wrist ulnar-basilic arteriovenous fistula formed in China-Japan Friendship Hospital from January 2013 and December 2014 were retrospectively analyzed.The outcomes for this study including the surgical results,complication rate of ulnar-basilic arteriovenous fistula,immediate patency rate,average maturation time,1-year primary patency rate and true patency rate were analyzed.Results Thirty-four cases patients got successful ulnar-basilic arteriovenous fistula formed with palpable vascular thrill.There were no death cases and no severe cardio-cerebrovascular complications.No infection,heart failure,distal swelling and ischemia occurred.The immediate patency of ulnar-basilic arteriovenous fistula was 94.4%(34/36),the average maturation time was (67±4) d,1-year primary patency rate was 63.9%(23/36),and true patency rate was 67.6%(24/36).Conclusion Ulnar-basilic arteriovenous fistula with adequate 1-year primary patency and low risk of infection and complications can be a viable alternative as the hemodialysis vascular access.

Objective:To analyze the cognition and willingness of family physicians on contracted service, and to explore the implementation obstacles and feasible strategies of implementing contracted service of family physicians from the perspective of suppliers.Methods:From July to October 2020, 850 family physicians in community health service centers or township health centers in three cities of Shandong Province were investigated by questionnaire survey and key person interview. Descriptive analysis and binary logistic regression model were used to analyze the willingness of family physicians to provide contracted service. Through questionnaire survey and key person interview, the implementation obstacles and service optimization strategies of family physicians were discussed.Results:791 valid questionnaires were obtained, of which 688(87.0%) approved the implementation of family physician contract service, and 679(85.8%) expressed willingness to provide family physician contract service. Marital status, recognition of service policy, satisfaction of service operation effect, optimistic degree of service development prospect and residents′ first choice of illness were the factors influencing family physician′s service willingness.Conclusions:We should effectively improve the family doctor′s service intention and promote the efficient and orderly implementation of family doctor′s contract service policy through enriching policy supporting measures, innovating the application of " Internet plus" , increasing personnel training, optimizing performance appraisal work and creating favorable public opinion environment.

Objective:To understand the willingness of contracted residents to renew the family doctor contract service in Shandong Province, and to explore its influencing factors.Methods:From July to August 2020, 1 500 contracted residents in 3cities of Shandong Province were investigated by questionnaire survey.Descriptive statistical analysis, Mann-Whitney U test and binary logistic regression model were used to analyze the contracted residents′ cognition, utilization, satisfaction evaluation and renewal intention of family doctor contract service. Results:1 445 valid questionnaires were obtained, of which 682(47.2%)were willing to renew their contracts.The results of binary logistic regression analysis showed that marital status, educational level, time to see a doctor in contracted institutions, optimism about the development prospect of contracted service policy, whether the proportion of medical insurance reimbursement increased after signing the contract, whether follow-up work was carried out on time, satisfaction with family doctor service attitude and satisfaction with the effect of disease treatment were factors affecting the willingness of contracted residents to renew the contract.Conclusions:The contracted residents in Shandong Province have a high willingness to renew their contracts. On the basis of consolidating and improving the policy cognition and confidence of the contracted residents, we should actively optimize and improve the contracted service quality, ensure the sense of service access of contracted residents, and continuously and effectively realize the comprehensive promotion of the contracted services of family doctors.

Objective:To explore the current status of medical preventive integration at primary medical institutions, analyze the problems of medical prevention integration, and put forward optimization suggestions.Methods:From June to July 2020, 169 primary medical institutions in a city were selected as the survey objects to conduct a questionnaire survey on the basic information of institutions and the evaluation indicators of medical preventive integration. The evaluation index system of medical preventive integration was divided into a factual survey and a sensory survey. In addition, 32 relevant personnel were interviewed on the current situation of medical preventive integration at primary medical institutions. The reliability and validity of the data were tested and analyzed, while descriptive analysis and classification extraction analysis were carried out.Results:The reliability and validity analysis proved the data reliability. The factual survey extracted three common factors, namely organization management, performance appraisal distribution and information management. The sensory survey extracted two common factors, namely working mode and personnel training. In terms of organization, management and working methods, the degree of medical preventive integration was low. Among them, 53.8% of the institutions had formulated the medical preventive integration norms, and only 41.4% of them had shared residents′ health information in time.Conclusions:The degree of medical preventive integration of primary medical institutions in the city still need to be improved. In the future, we should strengthen the top-level design, establish the norms and cooperation mechanism of medical preventive integration, improve the awareness of medical preventive integration of medical personnel, improve the information level, and to build a new service model integrating disease prevention, medical treatment and health management.

Objective:To evaluate and analyze the patient experience of residents contracted with primary medical institutions, for providing a basis for improving quality of contracted family doctor services.Methods:Using the Chinese version of the primary care assessment tools(PCAT), a household survey was conducted on 1 400 contracted residents in 9 community health service centers and 9 township health centers in a city from May to June 2020, and their medical experience in primary medical institutions was statistically analyzed. At the same time, interviews were conducted with institutional managers and family doctors. Descriptive statistics and one-way ANOVA were used for data analysis.Results:1 333 valid questionnaires were collected, and the effective recovery rate was 95.2%.The total PCAT scoring was 25.17. Seven dimensions of first contact, continuous, coordination, comprehensiveness, patient and family centered, community-oriented and cultural competence scored in average 3.57, 3.68, 3.54, 3.40, 3.72, 3.67 and 3.59 respectively.372 people(47.1%) had not been referred by the contracted institution before going to the superior hospital or specialized hospital. There were significant differences in the scores of four core dimensions in different types of institutions, age, education level, occupation and income( P<0.001). Conclusions:Given the initial progress of contracted family doctor services in the city, there is still room for improvement. It is suggested to further improve the comprehensiveness, coordinationand accessibility of services, and promote the high-quality development of contracted family doctor services.

Objective:To evaluate the current situation of comprehensive medical and health services of primary medical institutions in a city under the policy of family doctor contracted service, and explore the influencing factors and put forward improvement strategies, for the reference to improve the medical and health service level of primary medical institutions.Methods:In January 2021, 18 primary medical institutions in 3 counties(cities, districts) of a city in Shandong province were selected by stratified sampling method, and 60-70 contracted residents were selected from each institution for questionnaire survey. The questionnaire covered two dimensions: service provision(19 items) and metion frequency of health problems(12 items). According to the principle of information saturation, qualitative interviews were conducted with 20 family doctors and 15 contracted residents to identify the current service needs and existing problems. Descriptive analysis was used for all data, and single factor analysis of variance and multiple linear regression analysis were used for influencing factors of comprehensive service scores of primary medical institutions.Results:1 098 contracted residents were included in this study, and the comprehensive service score was 3.15±0.42. The vaccination, maternal health care and health education scored higher with 3.80±0.54, 3.70±0.64, 3.78±0.57 respectively; The dermatology, mental health counseling and family sickbed scored lower, with 2.27±1.20, 2.97±1.01 and 1.92±1.18 respectively. Contracted institution, gender, age and marital status were the influencing factors of comprehensive service scores( P<0.05). Residents′ needs for family sickbeds, psychological counseling and fall prevention had not been met. Conclusions:The primary medical institutions of the city had provided better basic public health services, while unmet needs were demand for home sickbeds, psychological counseling and fall prevention. We should take effective measures to increase the service supply based on the needs of residents, and provide more comprehensive medical and health services for residents at primary medical institutions.
