Objective To investigate the efficacy of endovascular stenting for aortic arch artery stenosis after nasopharyngeal carcinoma radiotherapy. Methods The clinical data of 8 patients with symptomatic severe aortic arch artery stenosis after nasopharyngeal carcinoma radiotherapy were analyzed retrospectively. The patients were all received endovascular stenting,and their improvement of cerebral ischemic symptoms was observed. They were followed up by cervical color Doppler ultrasound.Results The whole brain vascular DSA confirmed that there were 24 severe arterial stenoses on the aortic arch arteries of extracranial segments in 8 patients,including 11 in internal carotid artery,2 in common carotid artery,10 in vertebral artery and 1 in subclavian artery. The patients were treated with vascular angioplasty and stenting respectively. All the patients were followed up for 1 year;there were no recurrence of cerebral ischemic symptoms.Cervical color Doppler ultrasound did not reveal any obvious restenosis. Conclusion Endovascular stent angioplasty for the treatment of aortic arch artery stenosis after nasopharyngeal carcinoma radiotherapy is relatively safe and feasible.

Objective To investigate the clinical characteristics, operation time and methods for patients with central brain herniation caused by bifrontal contusions. Methods A retrospective study was performed on the medical records of patients with central brain herniation caused by bifrontal contusions admitted from January 2000 to December 2006. There were 45 males and 18 females, at age range of 20-72 years (average 43 years). The majority of the patients were victims of falls and traffic accidents. There were 29 patients treated with immediate operation and 34 with emergency operation. All the operations involved simultaneous bilateral craniectomy for decompression, including 17 patients treated with bilateral decompressive craniectomy and 46 with unilateral decompressive craniectomy. Results The prognosis was favorable in 19 patients with GOS score of 5 or 4 points, severely disabled in seven with GOS score of 3 points, vegetative in four with GOS score of 4 points and the worst in seven with GOS score of 1 point. Of all, 19 patients suffered severe mental disorders especially personality change and disturbance of intelligence. Seven patients were complicated by epilepsy and three by hydrocephalus. Conclusions Based on early clinical manifestations of central brain herniation combined with imaging manifestations, bilateral balance decompression craniectomy can reduce the mortality and morbidity and improve the cure rate of patients with central herniation caused by bifrontal brain contusions.

OBJECTIVE To develop an HPLC method for the simultaneous dete rmination of morroniside ，loganin，paeoniflorin， salvianolic acid B and icariin in Shenfukang Ⅱ capsule. METHODS The determination was performed on Agilent 5 TC-C18 column with mobile phase consisted of acetonitrile- 0.1％ phosphate acid （gradient elution ）at the flow rate of 1 mL/min. The column temperature was 30 ℃，and detection wavelength was set at 240 nm. The sample size was 10 μL. RESULTS The linear range of morroniside，loganin，paeoniflorin，salvianolic acid B and icariin were 4.80-240.00，4.84-242.00，7.00-350.00，4.72-236.00 and 5.18-259.00 μg/mL（r≥0.999 8），respectively. RSDs of precision ，stability and reproducibility tests were all lower than 3％（n＝6）. Average recoveries were 97.22％-101.36％ with the RSDs of 1.19％-2.43％（n＝6）. The contents of above 5 components in 5 batches of samples were 2.019 3-2.360 0，1.624 2-1.847 1，5.637 7-6.828 0，5.015 9-5.717 0 and 1.208 8-1.754 6 mg/g，respectively. CONCLUSIONS The method is simple ，accurate and reproducible. It can improve the quality control level of Shenfukang Ⅱ capsule.

ObjectiveTo support intelligent clinical decision-making in traditional Chinese medicine（TCM）， this study utilized ontology and knowledge graph construction techniques to achieve the IT application of clinical practice guidelines. MethodBased on the principles of findability， accessibility， interoperability， and reusability （FAIR principles）， this study employed ontology techniques to construct an ontology for TCM clinical practice guidelines and built a knowledge graph using coronary heart disease as an example. Based on the Checklist for Reporting Practice Guidelines in Traditional Chinese Medicine and Recommendation Grading in TCM Clinical Guidelines/Consensus （T/CAS 530—2021），the ontology of TCM clinical practice guidelines was constructed using the seven-step ontology construction method. On this basis，the TCM diagnosis and treatment data from the Guidelines for the Diagnosis and Treatment of Stable Angina Pectoris in Coronary Heart Disease were stored in Neo4j in the form of triples through knowledge extraction，integration，and storage. ResultThe information in the clinical practice guidelines was divided into three categories： onset and prevention information， diagnosis information， and treatment information， and the TCM clinical practice guideline ontology was constructed. A total of 27 concepts related to TCM clinical diagnosis and treatment and 14 data attributes were obtained， and 12 conceptual relationships including hierarchical relationships and object attributes were established. By taking coronary heart disease as an example and the TCM clinical practice guideline ontology as the model layer， the knowledge map of TCM diagnosis and treatment guidelines for stable angina pectoris in coronary heart disease with 276 nodes and 336 relationships was constructed， realizing the visual display and query of the guideline content. ConclusionThe ontology of TCM clinical practice guidelines and the knowledge graph of stable angina pectoris in coronary heart disease constructed by combining the seven-step ontology construction method and Neo4j graph database technology are efficient and flexible，providing an intelligent TCM diagnosis and treatment scheme and promoting the standardization and objectification of TCM diagnosis and treatment.

Chinese president Xi Jinping made clear at the National Health and Wellness Conference that health is the prerequisite for people's all-around development and a precondition for the sustainable development of China. Oral health is an indispensable component of overall health in humans. However, the long neglect of oral health in overall health agendas has made oral diseases an increasing concern. With this perspective, we described the global challenges of oral diseases, with an emphasis on the challenges faced by China. We also described and analyzed the recently released health policies of the Chinese government, which aim to guide mid-term and long-term oral health promotion in China. More importantly, we called for specific actions to fulfill the larger goal of oral health for the nation. The implementation of primordial prevention efforts against oral diseases, the integration of oral health into the promotion of overall health, and the management of oral diseases in conjunction with other chronic non-communicable diseases with shared risk factors were highly recommended. In addition, we suggested the reform of standard clinical residency training, the development of domestic manufacturing of dental equipment and materials, the revitalization traditional Chinese medicine for the prevention and treatment of oral diseases, and integration of oral health promotion into the Belt and Road Initiative. We look forward to seeing a joint effort from all aspects of the society to fulfill the goal of Healthy China 2030 and ensure the oral health of the nation.
