Objective To explore the effect of the treating left colon cancer,Compare left colon irrigation at one-stage radical colon resections were performed with the way which is given colon bracket insertion operation then two-stage radical colon resections were performed.Methods 32 cases sigmoid and rectum cancer patients with obstruction were received.And 14 cases were treated by colon irrigation at one-stage radical colon resections; 18 cases were treated by colon bracket insertion operation then two-stage radical colon resections were performed.To analyze the complications of after-operation、the average time in hospital.Results No occurence of anastomotic leakage was found in the two-stage radical colon resections.There was only one case was infected; the operation time(115 ± 26)min.The drainage in 3 days after the operation(127 ± 66)ml,length time(12.5 ± 3.2)d.The group of one-stage radical colon resections:the operation time(210 ± 39)min.The drainage in 3 days after the operation.length time(14.8 ±2.6)d,There was two cases of anastomotic leakage and 12 cases were infected and two dead were found in this group.Conclusion The way which was given colon bracket insertion operation then two-stage radical colon resections were performed,was better than colon irrigation at one-stage radical colon resections were performed,and with the first way patients life quality enhanced.

Objective:To survey the experiences and perception of caregivers on home care service for community-dwelling elderly.Methods:From August to December 2021, individual semi-structured in-depth interviews were conducted with caregivers of the elderly from five community health centers in Beijing Xicheng and Miyun districts selected by purposive sampling.Results:Nine caregivers,2 males and 7 females aged 49-76 (62.8±9.4) years were interviewed in this study. The nursing care period was 3-48 (17±13) years. Four themes were extracted from the interview data: older people′s own condition was the primary factor influencing the home care needs; medical needs for home care were determined by the caregivers′ factors; community health service was important for meet home medical needs; and supporting of home care services for the elderly need to be strengthened.Conclusion:The experience of elderly home caregivers in using community home medical services is affected by many factors, and in the future, the content of home medical services should be improved, and the skills training of community elderly home caregivers should be strengthened, so as to improve the quality of life at home and promote the health literacy of the elderly.

Objective:To investigate the perspective of family doctor teams on the status quo of home care for community-dwelling elderly.Methods:The focus group interviews on the status quo of home care for community-dwelling elderly were conducted from August 19 to December 28, 2021. One urban area and 1 suburban area of Beijing was selected by purpose sampling method as target areas. Five community health service centers were selected from each area, and 5 family doctor team members were selected as interviewees in each center. The outline of interviews was as follows: what kinds of home care does the family doctor team provide for the community-dwelling elderly; how does the family doctor team evaluate the existing community-based home care; what suggestions on developing community-based home care for the elderly in the future. The data of the interview were analyzed by the thematic framework.Results:Xicheng district and Miyun district were selected as the study sites in the urban and suburban areas of Beijing, and 41 family doctor team members were interviewed. Three themes and 6 sub-themes were extracted. The study showed that: (1) the family doctor contracted service for the elderly was carried out smoothly in the community; (2) the current situation of home care for the elderly in the community varied, the chronic disease management for the elderly was effective, the health education in the community was popular, the implementation of free annual health check for the elderly in urban areas was more difficult than that in suburban areas, and the family doctor team provided home visits as needed and required; (3) the members of family doctor team usually undertook multiple tasks due to the insufficiency of auxiliary staff, and the incentive mechanism of the home visit was not perfect, which needed to be improved.Conclusion:From the perspective of family doctor teams, the contract service for the elderly is generally carried out smoothly in Beijing communities, but it varies in different types of home care for the elderly, and the work and incentive mechanism of family doctor team need to be improved.

Objective : To explore the relationships among pharyngeal airway morphology, craniocervical posture, and anterior teeth position in hyperdivergent skeletal Class Ⅱ female adults and provide a reference for orthodontic clinical diagnosis and treatment. Methods: Lateral cephalometric radiographs of 104 untreated skeletal Class Ⅱ (ANB ≥ 4.7°) female adults were included and divided into a hyperdivergent group (MP-SN ˃ 37°) (n = 52) and a normodivergent group (29° ≤ MP-SN ≤ 37°) (n = 52) by mandibular plane angle. The pharyngeal airway sagittal size, craniocervical angulation and anterior teeth position of the two groups were measured. Results : Compared to the normodivergent group, hyperdivergent subjects exhibited narrower nasopharyngeal, velopharyngeal, and glossopharyngeal airways (P<0.05) and larger craniocervical angulations (P<0.05). In the hyperdivergent group, the nasopharyngeal airway sagittal size was negatively correlated with craniocervical angulations (P<0.05), while the hypopharyngeal airway sagittal size was positively correlated with craniocervical angulations in the hyperdivergent group and normodivergent group (P<0.05). In both groups, craniocervical angulations were negatively related to the labiolingual inclination of the upper incisors (P<0.05) but positively related to the inclination of the occlusal plane (P<0.05). Conclusion Hyperdivergent skeletal Class Ⅱ female adults had narrower upper airways and more extended craniocervical posture, which was correlated with pharyngeal airway morphology and anterior teeth position simultaneously. These results suggested that there were correlations among respiratory efficiency, craniocervical posture and dentofacial morphology.
