Acute basilar artery occlusion (ABAO) has a high rate of disability and mortality, and the key to its treatment is to start reperfusion therapy as early as possible. A number of retrospective studies have found that the good prognosis rate of endovascular treatment of ABAO is related to number of infarction locus, extent of ABAO, vascular occlusion and collateral circulation. Screening patients through imaging evaluation before endovascular treatment may further improve the rate of favorable outcome. This article reviews research progress on the correlation between imaging evaluation before endovascular treatment of ABAO and clinical prognoses.

Objective:
To understand the implementation of daily study time standard among secondary school students in Shandong Province, so as to provide scientific basis for the formulation and implementation of relevant policies.
Methods:
From January to May 2023, a multi stage random sampling method was used to select 8 725 middle school students in Shandong Province. A survey questionnaire was designed based on the Requirements for Daily Study Time of Primary and Secondary School Students(GB/T 17223-2012), to investigate indicators such as students daily learning schedule, sleep and physical activity time, break time and scheduling requirements.
Results:
The compliance rates for daily study time in junior and senior high school students in Shandong Province were 29.2% and 23.6%, respectively, with a statistically significant difference ( χ 2=33.63, P <0.01). Compliance rates for sleep duration, physical activity and recess time, morning and afternoon class hours, and class duration were 19.3%, 26.2%, 30.5%, 73.2% and 16.2%. Class duration compliance was relatively high, with rates of 96.7% in junior high and 94.4% in senior high school students. There was a statistically significant difference in compliance rates for extended class breaks between different educational stages ( χ 2= 81.78, P <0.01), with rates of 84.6% in junior high and 83.4% in senior high school students. As students progressed through their educational stages, compliance rates for physical activities, class breaks, consecutive classes, and total weekly class hours showed a decreasing trend, with rates of 31.8% and 18.3%, 35.7% and 23.1%, 60.5% and 29.6%, 55.2% and 35.1% in junior and senior high school students, respectively.
Conclusions
The revised standard of Requirements for Daily Study Time of Primary and Secondary School Students(GB/T 17223-2012) optimizes the daily study and life schedule of middle school students to a certain extent. However, daily study time for middle school students in Shandong Province exceeds standard. Relevant departments need to enhance their ability to implement standards and strengthen the supervision of policy standards implementation.

BACKGROUND:The reasonable implantation range of femoral prosthesis in unicompartmental knee arthroplasty in patients with osteoporosis has not been investigated,and previous studies have often been based on unicompartmental knee arthroplasty models in normal bone,with fewer mechanical studies in models with non-normal bone.Complications after unicompartmental knee arthroplasty have been shown to be highly associated with osteoporosis. OBJECTIVE:To analyze the biomechanical effects of the coronal inclination of the Sled fixed platform femoral prosthesis on unicompartmental knee arthroplasty in patients with osteoporosis and to find the correlation between osteoporosis and mid-and long-term complications after unicompartmental knee arthroplasty. METHODS:Based on the digital imaging technology to obtain the data of the knee joint and prosthesis,a normal bone knee model is then created by using specialized software such as Mimics and Geomagic studio.Based on a validated normal bone knee model,an osteoporotic knee model was created by changing the material parameters.Totally 14 unicompartmental knee arthroplasty finite element models were created using Sled fixed platform femoral prosthesis:standard position(0°),varus and valgus angles:3°,6°,9° in the normal bone and osteoporosis groups.Stress changes on the surface of polyethylene liner,cancellous bone under tibial prosthesis,and cortical bone were calculated and analyzed in all unicompartmental knee arthroplasty models. RESULTS AND CONCLUSION:(1)In the osteoporotic models,the high stress values of the polyethylene liner surface and the cancellous bone under the tibial prosthesis increased with the increase of the tilt angle of the femoral prosthesis,and the high stress values of the cortical bone surface under the tibial prosthesis increased with the increase of the prosthesis valgus angles and decreased with the increase of the varus angles.(2)For the polyethylene liner surface as well as the subcortical bone surface of the tibial prosthesis,the high stress values of the models for each inclination angle in the osteoporosis group were greater than those of the corresponding models in the normal bone group.For the surface of the cancellous bone under the tibial prosthesis,the high stress values of the tilt angle models of the osteoporosis groups were smaller than those of the normal bone groups.(3)Osteoporosis may cause biomechanical abnormalities in the internal structures of the knee after unicondylar replacement,increasing the potential risk of postoperative aseptic loosening of the prosthesis and periprosthetic fractures.Varus and valgus of the femoral prosthesis in the coronal plane should be avoided as much as possible when performing medial unicompartmental knee arthroplasty with a Sled fixation platform in osteoporotic knees.

ObjectiveTo analyze the epidemiological characteristics of varicella in Minhang District, Shanghai from 2013 to 2022, and to evaluate the impact of adjusting the varicella vaccination program to a two-dose regimen and its inclusion in the Shanghai immunization program on the incidence of varicella. MethodsData on reported varicella cases from 2013 to 2022 in Minhang District were collected. Interrupted time series analysis and segmented regression models were used to analyze the changes in varicella incidence before and after the adjustment of varicella immunization strategies. ResultsFrom 2013 to 2022, the average annual incidence of varicella was 76.58/100 000, with the highest incidence in 2017 (119.21/100 000) and the lowest in 2022 (27.02/100 000). The varicella incidence exhibited seasonal patterns with peaks occurring from March to June and October to January of the following year. Prior to the adjustment of varicella immunization strategies (2013‒2017), the varicella incidence showed an upward trend (z=2.20, P=0.03), while after the adjustment (2018‒2022), a adownward trend was observed (2018‒2022) (z=-2.25, P=0.02). Interrupted time series analysis showed that following the adjustment of varicella immunization strategies, an immediate change of -33.91/100 000 (t=-4.35, P<0.001) in varicella incidence was observed, and the incidence slope was -17.59/100 000 with a decline of 28.61/100 000 (t=-12.16, P<0.001) compared to before inclusion. ConclusionThe incidence of varicella in Minhang District, Shanghai from 2013 to 2022 exhibits distinct seasonal patterns. After adjusting the varicella vaccination program to a two-dose regimen and incorporating it into the immunization program, the second dose of varicella vaccine administration substantially increases. As a result, the rising trend of varicella incidence is effectively controlled, and the incidence level decreases significantly, showing a sustained downward trend.
