Objective:To summarize the clinical, pathological and molecular characteristics of various types of pediatric glioma, and to explore the differences in the morphology and clinical significance among various types of pediatric glioma.Methods:Based on the fifth edition of the World Health Organization classification of central nervous system tumors, this study classified or reclassified 111 pediatric gliomas that were diagnosed at Guangzhou Medical University Affiliated Women and Children′s Medical Center from January 2020 to June 2023. The clinical manifestations, imaging findings, histopathology, and molecular characteristics of these tumors were analyzed. Relevant literature was also reviewed.Results:The 111 patients with pediatric glioma included 56 males and 55 females, with the age ranging from 10 days to 13 years (average age, 5.5 years). Clinically, manifestations presented from 5 days to 8 years before the diagnosis, including epilepsy in 16 cases, increased intracranial pressure in 48 cases and neurological impairment in 66 cases. MRI examinations revealed tumor locations as supratentorial in 43 cases, infratentorial in 65 cases, and spinal cord in 3 cases. There were 73 cases presented with a solid mass and 38 cases with cystic-solid lesions. The largest tumor diameter ranged from 1.4 to 10.6 cm. Among the 111 pediatric gliomas, there were 6 cases of pediatric diffuse low-grade glioma (pDLGG), 63 cases of circumscribed astrocytoma glioma (CAG), and 42 cases of pediatric diffuse high-grade glioma (pDHGG). Patients with pDLGG and CAG were younger than those with pDHGG. The incidence of pDLGG and CAG was significantly lower in the midline of the infratentorial region compared to that of pDHGG. They were more likely to be completely resected surgically. The pDLGG and CAG group included 4 cases of pleomorphic xanthoastrocytoma, showing histological features of high-grade gliomas. Among the high-grade gliomas, 13 cases were diffuse midline gliomas and also showed histological features of low-grade glioma. Immunohistochemical studies of H3K27M, H3K27ME3, p53, ATRX, BRAF V600E, and Ki-67 showed significant differences between the pDLGG and CAG group versus the pDHGG group ( P<0.01). Molecular testing revealed that common molecular variations in the pDLGG and CAG group were KIAA1549-BRAF fusion and BRAF V600E mutation, while the pDHGG group frequently exhibited mutations in HIST1H3B and H3F3A genes, 1q amplification, and TP53 gene mutations. With integrated molecular testing, 2 pathological diagnoses were revised, and the pathological subtypes of 35.3% (12/34) of the pediatric gliomas that could not be reliably classified by histology were successfully classified. Conclusions:There are significant differences in clinical manifestations, pathological characteristics, molecular variations, and prognosis between the pDLGG, CAG and pDHGG groups. The integrated diagnosis combining histology and molecular features is of great importance for the accurate diagnosis and treatment of pediatric gliomas.

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.

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 define the connotation of village doctors′ vulnerability. Methods: On the basis of document analysis, Delphic method was used to consult and argument the connotation of village doctors′ vulnerability from October 2015 to November 2015. Results: Twenty and 16 specialists were consulted in two rounds of the consulting. According to these consultations, the acceptance rate of the specialists for the seven consulting units increased from 74.29% to 93.16%. Conclusions The vulnerability of village doctors was identified, as a status in which their self-ability and support against their exterior environment could not to cope with the disturbances they faced, while the vulnerability was co-determined by disturbance and response ability of village doctors.

Objective: To explore the current status of village doctors′ vulnerability in Shandong province in the context of ongoing healthcare reform. Methods: A cross-section study was conducted from October 2015 to November 2015 based on a self-designed questionnaire for village doctors. The questionnaire included 6 parts: fundamental state, disturbance from surroundings, disturbance from job, emotional support, instrumental support and self-ability of village doctors. Mean and standard deviation were adopted to describe the level of disturbance and support. Quadrant analysis was adopted to analyze village doctors′ vulnerability. The set pair analysis was adopted to calculate the vulnerability index and sample cluster analysis was adopted to classify village doctors based on the vulnerability index. Results: The total disturbance score was 3.39±0.46, and contribution from professional risk was the biggest(19.95%). The self-ability score was 3.33±0.40, and contribution from financial support was the smallest(4.09%). According to the set pair analysis, village doctors′ vulnerability total score was 0.49±0.06, ranging in a medium category. According to the sample cluster analysis, 27.2%(277/1 018)of the village doctors stayed at the upper category, as 30.3%(309/1 018) was defined as a medium category. According to the quadrant analysis, 35.5%(361/1 018)of the village doctors were found as in crisis vulnerability. Conclusions In general, village doctors′ vulnerability stays in the medium category. They have to fight against high disturbance from surroundings, with more emotional support and less financial support expected.

Objective: To explore the formation mechanism of the weakening of village clinic′s medical service capacity in the context of new medical reform. Methods: Purposive sampling method was used to enroll 38 rural doctors and managers of rural health centers and health offices in the interview from October 2015 to November 2015. And grounded theory was adopted to analyze reasons and their mechanism of the weakening of village clinic′ s medical service capacity. Results: 29 first-grade categories and 7 second-grade categories were worked out in text encoding. With the implementation of the ongoing healthcare reform, support from financial, policy and technology increased significantly, but due to the synthetic action of unexpected negative effects of the reform, superposition and accumulation of disturbance and ineffective support, village clinic′ s medical service capacity began to weaken. Conclusions The weakened village clinic′ s medical service capacity is a result of the synthetic action of 3 reasons. The persistence of this status will intensify the vulnerability of rural health service system and be bad for the implementation of hierarchical medical policy and the strategy of rural vitalization. Measures should be taken to optimization the essential medicine system, establish a comprehensive assessment mechanism for basic medical service and basic public health service of village clinic, strength the strategic purchasing of medical insurance, improve the financial compensation mechanism, and complete training system of village doctors, aims to promoting sustainable development of village clinic.

Objective:To investigate the cognition and willingness of nursing staff to Internet plus nursing service, and analyze the related factors that affect their participation in Internet plus nursing service.Methods:From April to May 2019, 150 nurses from three hospitals in Weifang were investigated by questionnaire and key person interview. Descriptive analysis and binary logistic regression analysis were used to analyze the intention of nursing staff to participate in Internet plus nursing service. The interview mode was used to analyze the appropriate mode of Internet plus nursing service from the perspective of nursing staff.Results:142 valid questionnaires were obtained, of which 137(96.5%)indicated willingness to provide Internet plus nursing services, and 135(95.1%) realized the necessity of the service. Education, marriage, nurses′judgment on the necessity of the service and their own subjective judgment of their competence were the factors affecting nurses′ participation in the Internet plus nursing service.Conclusions:Multiple factors affect the choice of nursing staff′s behavior in Internet plus nursing service.From the perspective of nursing staff, the Internet plus nursing service mode needs joint efforts from many aspects.

Objective: To explore the method of replanting severed piercing finger micro tissue blocks. Methods: From February, 2001 to October, 2016, 16 cases of severed piercing finger micro tissue blocks were replanted with debridement. The trunk or branch of proper palmar digital artery was anastomosed. Vascular collocations were used such as venous arterialization when there was no anastomotic artery available. Regular postoperative followed-up was performed to observe the recovery of tissue survival, appearance, sensation of flap, and joint function. Results: One case had partial epidermal necrosis, and healed after change of dressing. The finger-disconnected micro tissue blocks of other 15 cases survived well. After 6 months to 2 years of follow-up, the replanted micro tissue blocks were ruddy in color and recovered from S₃ to S₄. The appearance of the 16 fingers was good, and the function of joints was restored. Conclusion The finger-disconnected micro tissue blocks should be actively replanted. With skilled microsurgical techniques, the anastomosis of the arterial or venous artery will ensure the success of replantation and survived, as well as to restore good function and appearance.

The policy model of G. C. Edwards was used to study the policies on building a countywide medical community ( CMC), and identify problems in such aspects as policy communication, resources, disposition and bureaucratic structure. The analysis found that enriching health resources at primary level and powerful government support are creating ideal environment for the construction of CMC. But due to its preliminary development, rooms of improvement of its policy design, and unclear enforcement standards, there appear behavioral polarizations at local health authorities. For example, some are proactive to explore and accumulate rich experiences, while the most take a wait and see stand, or even take administrative means to cope with their authorities by forming medical communities in form only. A small part of county hospitals, thanks to support from the government and inherent conditions, take active measures in this direction as policy frontrunners. On the other hand, most county hospitals prefer to be policy followers in order to avoid cost and risks of the reform. In the worst cases, a few county hospitals have become free riders of the policy, and attempt to take advantages of their primary health institutions. Primary health institutions warmly embrace CMC, but their limited service capability constitutes roadblocks in CMC construction. What is more, poor communication and collaboration mechanisms among systems and authorities hinder the effective policy synergy and health service integration of CMS.
