Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To systematically analyze the framework and core content of physical activity inclusive school health policies. Methods This study conducted systematic content analysis of key messages of WHO key documents related to physical activity and school health services, and constructed policy and research framework. WHO's key policy documents in the field of school health included: Making Every School a Health-Promoting School Implementation Guidelines, WHO Guidelines on School Health Services, and the Global Criteria and Indicators for Making Every School a Health-Promoting School, and the key documents in the field of physical activity mainly include Global Action Plan for Physical Activity Promotion 2018-2030: Strengthening Physical Activity for a Healthy World, and WHO Guidelines on Physical Activity and Sedentary Behavior (Children and adolescents). Results Physical activity, as a health strategy and development strategy, is one of the most important tools for achieving health-promoting schools. In the area of health and education, the key to building health-promoting schools is to focus on child functioning and development, with the goal of promoting healthy inclusion and equity in schools. In the school setting, physical activity for children and adolescents is integrated into the school health service continuum with a focus on health promotion. At the macro level, the state and relevant authorities should establish a strategic structure and strategic planning for the integration of physical activity into the school health service system. At the meso level, educational institutions should develop and improve school health service policies and programs, and improve school health service tools based on the requirements of WHO school health service guidelines. Child health services are achieved through the provision of high-quality physical education programs and after-school physical activities. At the micro level, guided by global standards for building health-promoting schools, physical activity is promoted in the form of lessons and activities for healthy child development. Integrating physical activity into the school health service system can be done in six areas: school health leadership and governance, school infrastructure funding, school health service delivery that supports physical activity, human resources for school health, school health-related medicine and technology, and school health information system. We need to implement health-promoting school policies, strengthen multi-level school leadership and governance, raise the necessary funds to develop human resources adapted to the construction of health-promoting schools and build programs to support physical activity. Conclusion School health service is an important area for promoting children's health and achieving the UN 2030 Sustainable Development Goals, and physical activity is an important strategy of school health services. Policy documents issued by WHO construct the integration of physical activity into the policy framework of the school health service system, of which the core component is to integrate physical activity into the health-promoting school with educational and physical activity approaches. According to the WHO six building blocks of health service system, the integration of physical activity into the school health requires strengthening school health leadership and governance, improving school infrastructure financing, developing school health human resources, developing school-based health-related medical technologies, and establishing a health information system for sharing student health data.

Objective To explore the theories, content and approaches of integrating physical activity in children's eye health service system in the context of health services. Methods From the perspectives of six building blocks of WHO health system, namely, leadership and governance, financing, human resources for health, service delivery, medical technology, and health information system, we analyzed the policy framework and key contents related to school-based eye health and physical activity, and explored how to promote the implementation of physical activity into the school-based eye health service system, and the integration of physical activity into the eye health continuum: prevention, intervention, rehabilitation, and health promotion. Results In perspective of health system, the integration of physical activity into school-based eye health services should be in accordance with the five principles of cross-cutting health services, namely, universal accessibility and equity, human rights, evidence-based, life-span, and empowerment. According to the World Vision Report, WHO advocates to build a person-centered eye health service system, and person-centeredness is the core concept of the new model of school-based eye health services and physical activity integration. WHO advocates a school-based approach to education and physical activity in health-promoting schools to promote student health, physical activity as a preventive, interventional, rehabilitation and health promotive measure related to children's eye health, and vigorously train professionals within schools who have knowledge and skills related to physical activity and eye health, build an information system on physical activity and children's eye health, and promote the integration of physical activity into the school-based eye health service system. Conclusion Physical activity is an important measure to promote children's eye health and an important component to achieve a person-centered eye health service system. Based on the six building blocks of the WHO health service system, a school-based eye health service that integrates a theoretical and methodological system of physical activity is constructed, requiring the provision of health promotion methods such as education and physical activity in the school setting, to enhance leadership and governance of eye health services based on educational and physical activity approaches in the school setting, establish new funding mechanisms, provide financial security, develop human resources related to physical activity for eye health, improve related service delivery systems, develop high-quality physical activity intervention eye health techniques and equipment, and integrate information on children's physical activity and eye health into school health information systems to achieve children's eye health and promote their physical and mental development.

Objective To explore pediatric nurses' perceptions about patients' safety culture and identify the factors that affect patients' safety culture so as to provide evidences for improving patients' safety. Methods A cross-sectional study with convenience sampling was performed on 886 pediatric nurses working in a children's hospital from July 2016 to September 2016. Patients' safety culture was assessed using the Chinese version of the Hospital Survey on Patient Safety Culture.Results 74.1% of nurses evaluated patients' safety grade as either 'very good' or 'good'. The advantage areas with positive responsive rates higher than 75% were described as follows "feedback and communication about error", "teamwork within units" and "organizational learning and continuous improvement". Areas need to be improved with positive responsive rates lower than 50% included "staffing" and "frequency of events reported". Multiple linear regression analysis indicated that ages and overtime work of nurses were main factors that affected nurses' knowledge of patients' safety culture. The two factors explained 10.8% of total variation.Conclusions Nurses in the children's hospital has an overall high level of knowledge to patients' safety culture. However, several aspects need to be improved. It is necessary to provide positive interventions to factors that affect knowledge of safety culture.

OBJECTIVETo construct wild-type and mutant pEGFP SPAST vectors and to explore the molecular mechanism of hereditary spastic paraplegia.

METHODSMutant SPAST vector was constructed using overlap PCR method following construction of wild-type SPAST vector. Wild-type and mutant constructs were transfected to COS7 cells and subcellular localization of spastin was observed. Co-localizations of spastin and microtubule, spastin and mitochondria were viewed by immunofluorescence staining.

RESULTSWild-type spastin is localized in plasma, and mutant spastin did not change its cellular localization. Wild-type and mutant spastins did not co-localize with microtubules and mitochondria by immunofluorescence analysis.

CONCLUSIONWild-type and mutant SPAST constructs were successfully generated. Mutant spastin did not change its localization in cells. Spastin does not co-localize with microtubules and mitochondria. This study may facilitate further studies on molecular mechanism of hereditary spastic paraplegia.

Objective To explore the effect of methylprednisolone combined with HBO on acute lung injury (ALI) induced by rush decompression.Methods Twenty-six male healthy rabbits were randomly divided into the normal control group (n =6),the model group and the combined therapy group.Four animals in the model group and the combined therapy group died,following development of the ALI model by rush decompression by using vacuum pumps.Then,the remaining 24 animals were randomly divided into the model group and the combined therapy group,each consisting of 12 animals.The moment after the animals were surfaced from the chamber,4 animals in each group were sacrificed for the detection of wet/dry ratio of the lung tissue.The remaining animals in the model and control groups were given normal feeding for 3 days,without any treatment.Following injection of methylprednisolone (1 mg/kg),the animals in the combined therapy group were exposed to HBO (0.1 MPa gauge pressure,breathing oxygen for 2 hours),one session a day for a succession of 3 days.Three days later,observations were made on the wet/dry ratio of the lung tissue,pathologic morphology,concentrations of TNF-α and IL-1β,and the expressions of NF-κB p65 mRNA.Results The moment and 3 days after rush decompression,the wet/dry values of the animals in the model group were (5.29 ±0.26,3.20 ±0.21),which were higher than those of the animals in the control group (2.32 ±0.54,2.15 ±0.40) (P ＜0.01).Significant pulmonary exudation and inflammatory infiltration could obviously been seen.Three days after treatment with methylprednisolone combined with HBO therapy,the wet/dry value of the animals in the treatment group decreased significantly (2.34 ± 0.49),without statistical significance,when compared with that of the control group.However,statistical significance could be noted,when compared with that of the model group.Three days later,concentrations of TNF-α and IL-1β of the model group increased [(9.53 ± 1.28),(20.34 ± 1.87) ng/L)],which were significantly higher than those of the control group [(6.42 ±0.95),(15.63 ± 1.85) ng/L)] (P ＜ 0.05 or P ＜ 0.01).The expressions of NF-κB p65 mRNA (1.32 ± 0.48) also increased,when compared with those of the control group (0.35 ± 0.07) (P ＜ 0.05).After 3 days of combined treatment with methylprednisolone and HBO,acute lung injury score of the treatment group was(4.43 ± 0.93),which showed a significant improvement,when compared with that of the model group (8.56 ± 1.73) (P ＜ 0.01).Nevertheless,it was still rather high,when compared with that of the control group(0.97 ± 0.17)(P ＜ 0.01).The concentrations of TNF-α and IL-1β in the homogenates decreased [(7.17 ±0.65),(16.63 ± 0.57)ng/L],which were significantly lower than those of the model group [(9.53 ± 1.28),(20.34 ± 1.84) ng/L) (P ＜ 0.05).In the meantime,the expression of N F-κB p65 mRNA also declined markedly (0.43 ±0.15),when compared with that of the model group(1.32 ±0.48) (P ＜ 0.05).Conclusions The combined treatment of methylprednisolone and HBO could produce positive effects on acute lung injury induced by rush decompression,the inhibition in the expression of NF-κB p65 might be one of the mechanisms involved.

OBJECTIVETo observe the effect of SSd on reversing the malignant phenotype of HepG2 cells and to investigate its mechanism in order to prove that SSd is a new choice to prevent and treat HCC.

METHODSHepG2 cells were cultured and treated by different concentration (0 mg/L, 2.5 mg/L, 5.0 mg/L, 10.0 mg/L and 20.0 mg/L) of SSd for 24 h, and treated by 10 mg/L of SSd for 0 h, 6 h, 12 h, 24 h, 48 h and 72h respectively. The cell inhibition rates were measured by MTT assay. Then cells were treated by 10 mg/L SSd for 48 hr in experimental group and treated by no SSd as a control, their morphological changes were observed by contrast phase microscope. The concentrations of ALB and AFP in clear supernatant liquid of cells were detected by radio-immunity and chemiluminescence. The cell migration rates were observed by transwell method, the relative expression levels of p27 mRNA were measured by RT-PCR.

RESULTSThe inhibitive effect of 10 mg/L SSd was the most significant among different concentrations ( F = 265.06, P less than 0.01). The shape of HepG2 from experimental group turned into small and round, and their volume ratios of nucleus to plasma decreased. ALB in supernatant liquid of HepG2 was higher ( t = 7.83, P less than 0.05, and its AFP was lower ( t = -10.72, P less than 0.01) as compared to control group. Cells migrated were fewer and p27 mRNA expression of HepG2 was higher in experimental group than that in control group (t = 22.00, P less than 0.05).

CONCLUSIONSSd could reverse the malignant phenotype of HepG2 cells. It was suggested that the up-regulation of p27 mRNA expression play an important role in the differentiation of HepG2 cells treated by SSd.
