Atopic dermatitis （AD） is a common pruritic and chronic inflammatory dermatosis in clinical practice and is one of the diseases responding specifically to traditional Chinese medicine （TCM）. With the launch of biological agents and small molecule drugs and the development and implementation of guidelines of diagnosis and treatment， clinical pathways of treatment of moderate to severe AD， and consensus on the whole-process management of AD， the clinical efficacy of moderate to severe AD has been significantly improved. However， there are still many unmet clinical needs that require more effective methods to meet. In response to the Opinions of the CPC Central Committee and the State Council on Facilitating the Inheritance， Innovation， and Development of Traditional Chinese Medicine and the spirit of the National Conference on TCM， the China Association of Chinese Medicine organized more than 20 experts in TCM dermatology， Western medicine dermatology， interdisciplinary fields， and industries to discuss the difficulties and advantages of TCM in the treatment of AD. TCM treatment for AD can not only improve rash and relieve itching but also solve many concomitant syndromes. The abundant external treatment methods of TCM have advantages for different special populations and rash characteristics. The concept of treating disease before its onset in TCM is in line with the chronic disease management mode of prevention and treatment of atopic march and prevention of recurrence. In addition， TCM therapy can reduce the use of topical glucocorticoids and has good safety. Regarding the comorbidity of AD， equal emphasis on TCM and Western medicine and multidisciplinary joint treatment should be advocated to achieve maximum benefit for patients. The exchange of TCM and Western medicine has clarified the positioning and advantages of TCM intervention in AD， providing guidance for clinical and scientific research.

The patients with skeletal class Ⅱ malocclusion are often accompanied by structural and functional abnormalities of the upper airway,and obstructive sleep apnea hypopnea syndrome(OSAHS)may occur in severe cases.The morphologic and fluid dynamic changes of the upper airway in one patient with skeletal class Ⅱ malocclusion accompanied by OSAHS after maxillomandibular advancement(MMA)surgery were observed.The patient was a 27-year-old male with skeletal class Ⅱ malocclusion and moderate OSAHS.Combined orthodontic and orthognathic treatment was conducted,involving the anterior movement of the maxilla and mandible.After surgery,the patient's facial and intraoral features showed a satisfactory occlusion relationship with normal overbite,overjet and canine-molar relationships.There was also a significant improvement in the upper airway flow field.Two years after surgery,the cross-sectional area of the nasopharyngeal airway increased by 10.76％with a 55.36％reduction in pressure.The oropharyngeal airway showed a 108.25％increase in cross-sectional area with a 98.14％pressure reduction.The hypopharyngeal airway exhibited a 97.51％increase in cross-sectional area with a 351.03％pressure reduction.The laryngopharyngeal airway demonstrated a 27.54％increase in cross-sectional area with a 95.62％pressure reduction.The apnea-hypopnea index(AHI)decreased by 55.45％,achieving the treatment goal.Morphological measurements combined with fluid dynamic analysis can comprehensively evaluate the condition of the upper airway.The approximate value of the critical closing pressure(Pcrit)obtained from computational fluid dynamics(CFD)analysis may serve as a simple quantitative indicator for assessing the upper airway condition.

In order to further promote the standardization of the integrated traditional Chinese and western medicine treatment of atopic dermatitis(AD),the team of Professor Chen Dacan,who is honored as the Qihuang Scholar,developed the Clinical Practice Guidelines for Integrated Traditional Chinese and Western Medicine in Atopic Dermatitis(hereinafter referred to as Guidelines for AD).This paper detailed the process of development of Guidelines for AD,and analyzed the characteristics of Guidelines for AD,as well as the difficulties and countermeasures encountered during such a time.The development of Guidelines for AD follows the methodology of international guidelines for clinical trial.Experts specializing in various disciplines,such as traditional Chinese medicine,western medicine,integrated traditional Chinese and western medicine,and methodology,composed an expert group and a working group.On the basis of systematic literature research,the clinic experiences of frontline experts were well-summarized,and the draft of Guidelines for AD was formed after several meetings and discussions.In the process of developing Guidelines for AD,quite a number of problems were encountered,and the project team found the corresponding countermeasures after analyzing these problems.The countermeasures became the characteristics of Guidelines for AD:the integration of traditional Chinese medicine therapies and western medicine therapies,and the evaluation of the evidence of integrated traditional Chinese and western medicine solved the problem of traditional Chinese and western medicine diagnosis and treatment of AD lacking standardization;the adequately combination of the evidence with the experience of clinical practice solved the problems of the low overall level and the insufficiency of traditional Chinese medicine evidence for AD;the establishment of management goals and strategies for AD after taking the advantages of both traditional Chinese medicine and western medicine into account was in line with the international treatment and management concepts;the formulation of individualized traditional Chinese and western medicine therapy based on the integration of traditional Chinese medicine therapy and western medicine therapy met the clinical needs of patients with different characteristics of AD.The development process of Guidelines for AD and the analysis of problems and countermeasures during such a time will provide reference and reflection for the subsequent establishment of clinical guidelines for the integrated traditional Chinese and western medicine in other diseases.

Magnetic fields are safe and used in noninvasive physical therapies. Numerous studies have confirmed that magnetic fields have good osteogenic effects and certain value for clinical application in accelerating orthodontic tooth movement, promoting bone-implant integration, promoting fracture healing and improving the effects of distraction osteogenesis. Magnetic fields are expected to become applied as effective auxiliary methods for treating oral diseases. To support the clinical application of magnetic fields, this article reviews the applications of magnetic fields in the oral cavity, the biological effects on bone cells and the molecular mechanisms through which magnetic fields regulate bone metabolism. The biological effects of magnetic fields on bone cells include promoting osteogenesis by osteoblasts and mesenchymal stem cells and inhibiting bone resorption by osteoclasts. At the molecular level, bone cells sense and respond to magnetic stimulation, and through various mechanisms, such as displacement currents, Lorentz forces, and free radical pair effects, stimuli are transformed into biologically recognizable electrical signals that activate complex downstream signaling pathways, such as the P2 purinergic receptor signaling pathway, adenosine receptor signaling pathway, transforming growth factor-β receptor signaling pathway, mammalian target of rapamycin (mTOR) pathway, and Notch pathway. In addition, magnetic parameters, which are the factors affecting the osteogenic effects of magnetic fields, are discussed. However, the mechanisms of the osteogenic effects of magnetic fields are unclear, and further studies of these mechanisms could provide effective strategies for bone regeneration and periodontal tissue regeneration. In addition, considering the target of magnetic field therapies, combination with other drugs could lead to new strategies for the treatment of oral diseases.

OBJECTIVE To investigate the ameliorative effects and mechanism of Sanwei ganlu on hepatic fibrosis in rats. METHODS The rats were randomly divided into normal group， model group， silibinin group （positive control， 50 mg/kg）， and Sanwei ganlu low-dose， medium-dose， and high-dose groups （80， 250， 800 mg/kg）. Except for normal group， hepatic fibrosis rat models were established by intraperitoneal injection of CCl4 in the other groups of rats. Starting from the 6th week of modeling administration， they were given normal saline or corresponding drugs intragastrically at the same time. At the end of the ninth-week experiment， liver and spleen indexes of rats were calculated； the pathological structure and fibrosis changes of liver tissue were observed by HE， Masson and Sirus Red staining. The contents of alanine transaminase （ALT）， aspartate transaminase （AST）， procollagen type Ⅲ （PC Ⅲ）， collagen type Ⅳ （COL-Ⅳ）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） and IL-1β in serum， and hyaluronic acid （HA） and laminin （LN） in liver tissue were all detected. RESULTS Compared with the model group， the liver injury and collagen fiber deposition of rats were improved to different extents in Sanwei ganlu groups and silibinin group； the contents of ALT， AST， PC Ⅲ， COL-Ⅳ， IL-6， TNF-α and IL-1β in serum as well as the contents of HA and LN in liver tissue significantly decreased （P＜0.05 or P＜0.01）. CONCLUSIONS Sanwei ganlu can alleviate the progression of hepatic fibrosis in rats， possibly by inhibiting the synthesis of collagen fiber， reducing transaminase content， down-regulating the levels of HA， LN， PC Ⅲ and COL-Ⅳ， and reducing the inflammatory response.
