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.

The continuous cropping obstacle of Panax notoginseng is serious, and effective control measures are lacking. Soil disinfection with chloropicrin(CP) has been proven to be effective in reducing the obstacles to continuous cropping of other crops. In order to ascertain the effect of CP in the continuous cropping of P. notoginseng, this paper explored the influences of CP at different treatment concentrations(0,30,40,50 kg/Mu, 1 Mu≈667 m~2) on soil macro-element nutrients, soil enzyme activity, growth and development of P. notoginseng, and the accumulation of medicinal components. The results showed that CP fumigation significantly increased the content of total nitrogen, alkali-hydrolyzable nitrogen, ammonium nitrogen, nitrate nitrogen, and available phosphorus in the soil, but it had no significant effect on potassium content. The soil protease activity showed a trend of first increasing and then decreasing with the prolonging of the treatment time. Both the soil urease and acid phosphatase activities showed a trend of first decreasing and then increasing with the prolonging of the treatment time. The higher the CP treatment concentration was, the lower the urease and acid phosphatase activities would be in the soil. The protease activity was relatively high after CP40 treatment, which was better than CP30 and CP50 treatments in promoting the nitrogen-phosphorus-potassium accumulation in P. notoginseng. The seedling survival rates after CP0, CP30, CP40, and CP50 tratments in October were 0, 65.56%, 89.44%, and 83.33%, respectively. Compared with the CP30 and CP50 treatments, CP40 treatment significantly facilitated the growth and development of P. notoginseng, the increase in fresh and dry weights, and the accumulation of root saponins. In summary, CP40 treatment accelerates the increase in soil nitrogen and phosphorus nutrients and their accumulation in P. notoginseng, elevates the seedling survival rate of P. notoginseng, enhances the growth and development of P. notoginseng, and promotes the accumulation of medicinal components. CP40 treatment is therefore recommended in production.

Objective To explore the functional status and influencing factors of physical fitness of children with intellectual and developmental disabilities enrolled in special education, and to establish framework of physical fitness for analysis of physical fitness and exercise intervention using International Classification of Functioning, Disability and Health (ICF). Methods Based on the ICF apporach, we analyzed the functional status and physical fitness characteristics and influencing factors of students in special education schools, and developed a function-based physical fitness intervention program for children with intellectual and developmental disabilities with reference to the requirements of WHO Guidelines on Physical Activity and Sedentary Behavior (2020). Results A systematic analysis of the overall functional status of children with intellectual and developmental disabilities based on ICF, especially intellectual functions, activities and environmental factors related to intellectual disability, was conducted and discussed in the context of related motor functions and physical fitness. A physical activity program was developed based on the ICF and with reference to WHO Guidelines on Physical Activity and Sedentary Behavior (Children and Adolescents), and related adaptive support strategies were proposed. Conclusion The overall functional status of children with intellectual and developmental disabilities has been analyzed in body functioning (both intellectual and motor), activity and participation, and environmental factors. Based on WHO Guidelines on Physical Activity and Sedentary Behavior and the ICF framework, a physical activity program for physical fitness with adaptive and supportive teaching and training methods, has been developed for children with intellectual and developmental disabilities.

Scutellaria baicalensis (S. baicalensis) and Scutellaria barbata (S. barbata) are common medicinal plants of the Lamiaceae family. Both produce specific flavonoid compounds, including baicalein, scutellarein, norwogonin, and wogonin, as well as their glycosides, which exhibit antioxidant and antitumor activities. Here, we report chromosome-level genome assemblies of S. baicalensis and S. barbata with quantitative chromosomal variation (2n = 18 and 2n = 26, respectively). The divergence of S. baicalensis and S. barbata occurred far earlier than previously reported, and a whole-genome duplication (WGD) event was identified. The insertion of long terminal repeat elements after speciation might be responsible for the observed chromosomal expansion and rearrangement. Comparative genome analysis of the congeneric species revealed the species-specific evolution of chrysin and apigenin biosynthetic genes, such as the S. baicalensis-specific tandem duplication of genes encoding phenylalanine ammonia lyase and chalcone synthase, and the S. barbata-specific duplication of genes encoding 4-CoA ligase. In addition, the paralogous duplication, colinearity, and expression diversity of CYP82D subfamily members revealed the functional divergence of genes encoding flavone hydroxylase between S. baicalensis and S. barbata. Analyzing these Scutellaria genomes reveals the common and species-specific evolution of flavone biosynthetic genes. Thus, these findings would facilitate the development of molecular breeding and studies of biosynthesis and regulation of bioactive compounds.

OBJECTIVEThis study was to investigate the cell morphology and cell immune phenotypic characteristics in patients with multiple myeloma (MM).

METHODSThe flow cytometry with multiparametric direct immunofluorescence technique, and CD45/SSC and CD38(+)(+)/CD138(+) gating were used to measure cell markers CD138, CD38, CD56, CD117, CD3, CD13, CD33, CD19, CD7, CD20, CD22, CD34, CD28 in 47 MM patients. At the same time the morphology examination of bone marrow cells was performed.

RESULTSThe suspicious myeloma cell ratio in MM patients was 9.42%-74.25% detected by flow cytometry, moreover, the myeloma cell ratio detected by morphology examination was 11.0%-80.6%, there was a good correlation between the two detection methods (r(2) = 0.54, P < 0.001). The ratio of antigen positive expression was as follows: 74.46% for CD138, 100% for CD38, 57.44% for CD56, 40.42% for CD117, 6.38% for CD13, 19.15% for CD33, 8.51% for CD20, 27.66% for CD28, 2.12% for CD22, 4.25% for CD34, 0% for CD3, 0% for CD19, 0% for CD7.

CONCLUSIONSCD45/SSC and CD38(+)/CD138(+) gating technique can accurately gate multiple myeloma cell sets which need analysis, the majority of myeloma cells expreses CD138, CD38, CD56 antigens. The immunophenotypic analysis combined with the cell morphology examination more contribute to the diagnosis and differential diagnosis of multiple myeloma.

Objective To determine the load of causing parachutist's lateral collateral ligament and the joint capsule injuries by investigating the ankle inversion from plantar flexion to varus position under simulated landing state,and to analyze its stress features in order to provide theoretical reference to the development of Chinese Air Force Paratrooper boots and ankle brace.Methods Six human ankle specimens were fixed on the MTS-858 biomechanical testing machine by the self-made fixture.The axial compression range was 10 cm.The axial force was applied until the load curve appeared peak.The force and the time to peak were recorded,as well as the load time curve.Results In the simulation of ankle inversion from plantar flexion to varus position,the average peak force was 2207.18 N,and the average time to the peak was 9.76 s.The load curve showed such feature as gradual increase and sharp drop.The dissection showed that the lateral collateral ligament and the joint capsule had inactive ruptured injuries with irregular section as the peak force applied.X-ray examination indicated no osseous injuries in all specimens.Conclusions The ankle's lateral collateral ligament and joint capsule would show isometric and isotonic contraction features in the load-time curve as overcoming the ankle change from plantar flexion to varus position under simulated landing state.Those would provide theoretical reference in improving paratrooper boots and ankle brace in order to prevent ankle from lateral collateral ligament and the related soft tissue injuries.
