In the view of the idea that the utilization of wild plants and animals in traditional Chinese medicine is destroying the biodiversity, this article discusses the relationship between traditional Chinese medicine and the biodiversity from a new point of view. The authors consider that reasonable utilization of the wildlife in traditional Chinese herbal medicine is beneficial to the protection of wildlife under proper management and guidance. However, there is still a long way to go to balance the relationship between the wildlife protection and exploration. In view of this, some propositions are put forward, including enforcing the relative laws and rules for herbal resources protection, carrying out the research work of the background data, formulating the standard for the classification of the rare and endangered species, accelerating the investigation of the substitute resources of extinctive wildlife for medical use, enforcing the citizens' consciousness of wildlife protection and developing the industrial and artificial cultivation of traditional Chinese herbal medicinal plants and animals.

Objective To investigate the correlation between serum interleukin-8 (IL-8 )and immunoglobulin/complement 3A (IgA/C3)and immune imbalance in Henoch-Schonlein Purpura(HSP)in children,and provide evidence and guidance for clinical therapy of HSP.Methods Serum IL-8 was measured by Enzyme-linked immunosorbent assay(ELISA),and IgA and C3 were de-tected by automatic biochemistry analyzer,and calculate the ratio of IgA/C3.Results Serum IL-8 levels were (389±5 1.68)ng/L, significantly higher than that in healthy children (P < 0.05 ).Serum IgA levels were(306.2 ± 32.21 )mg/L,significantly higher (P <0.05).Serum C3 levels were (1 14.5 ±20.7)mg/L,of no statistical difference.IgA/C3 were (3.041 ±0.508 5),significantly higher(P <0.05).There was a positive correlation between IL-8 and IgA/C3 (r =0.534,P <0.05 ).Conclusion The children of HSP has cytokine and immunoglobulin disturbance,and presents a hyperreactivity in both humoral immunity and cellular immunity. Positive correlation between IL-8 and IgA/C3 was observed.

Objective:Managing 33-C3 femur fractures with medial wall bone defects poses a significant challenge for orthopedic surgeons.The gold standard treatment for arbeitsgemeinschaftfür osteosynthesefragen(AO)/orthopedic trauma association(OTA)33-C3 distal femur fractures with medial wall bone defects remains elusive.This study employs finite element analysis to compare the stability and mechanical behavior of 3 internal fixation patterns(single lateral distal locking plate,retrograde intramedullary nail,and dual plates)for 33-C3 femur fractures with medial wall bone defects.The aim is to provide a theoretical basis for the selection of internal fixation modalities in clinical practice. Methods:Enrollment included a 43-year-old male volunteer weighing 60 kg,without a history of femur fracture.Bilateral femur normality was verified through X-ray and CT scan assessments.A finite element simulation model of AO/OTA 33-C3 distal femur fracture with medial wall bone defect was established.Three fixation methods,named single lateral locking plate(single-plate group),retrograde intramedullary nail(retrograde intramedullary nail group),and dual plates(dual-plate group),were evaluated using finite element analysis under an axial load of 300 N.The assessment included an examination of von Mises stress distribution,shear stress,and displacement patterns at the internal fixation and femur fracture sites. Results:The finite element analysis revealed that dual-plate fixation effectively reduced the concentration of von Mises stress at the plate on the fracture site.Under full weight-bearing conditions,the maximum von Mises stress in the implants occurred at the distal femur defect level,with values of 149.30,59.281,and 58.03 MPa for single-plate fixation,retrograde intramedullary nail,and dual-plate fixation methods,respectively.Similarly,the maximum shear stress in the implants was 77.867,30.136,and 33.505 MPa for single-plate fixation,retrograde intramedullary nail,and dual-plate fixation methods,respectively,all presenting at the distal femur defect level.The maximum relative displacements of implants during compressive loading were 1.34,1.25,and 0.83 mm for the single-plate,retrograde intramedullary nail,and dual-plate groups,respectively.Consistently,the maximum loading-point displacements of fracture sites were 1.529,1.264,and 0.880 mm for the single-plate fixation group,retrograde intramedullary nail group,and dual-plate fixation group,respectively.Furthermore,at the distal femur defect level,the maximum von Mises stress was 72.682,112.430,and 40.716 MPa for the single-plate,retrograde intramedullary nail,and dual-plate fixation groups,respectively. Conclusion:Dual-plate fixation demonstrates superior biomechanical outcomes and exhibites the lowest maximum von Mises stress and shear stress,along with minimal relative movements between fracture fragments.This configuration offers optimal mechanical stability for managing AO/OTA 33-C3 distal femur fractures with medial wall bone defects.Consequently,dual-plate fixation emerges as a better treatment strategy for patients presenting with comminuted intra-articular distal femur fractures accompanied by medial wall bone defects.

OBJECTIVE: To provide transnasal endoscopic optic canal decompression with the anatomic reference. METHOD: 15 samples of the adult corpse wet specimen (30 sides for the optic canal) were examined under the endoscope to scrutinize the regional anatomy of the optic canal. RESULT: distance between the spina nasalis anterior and the midpoint of optic canal medial wall is (61.02 +/- 5.83) mm, and the angle between spina nasalis anterior and the midpoint of optic canal medial wall is (45.1 +/- 4.81) degrees. The medial wall of optic canal is longest, with an average length of (11.61 +/- 1.58) mm; the lateral wall of optic canal is thickest, and the medial wall thinnest. 10 traumatic blind patient underwent endoscopic optic canal decompression with satisfactory outcome. CONCLUSION The regional anatomy of the optic canal under endoscope is of importance to endoscopic optic canal decompression. Which is microinvasive with direct approach and clear view thus is widely used in clinical practice.
