BACKGROUND: Nowadays, it is reported that vessel structural abnormity is the main morphological basis of vertigo due to vertebrobasilar arterial insufficiency abroad, but the report of vascular structural abnormality in vertebrobasilar arterial insufficiency is rare at home.OBJECTIVE: To observe the manifestation and clinical significance of vessel structural abnormity tested by digital substraction angiography (DSA)in patients with vertigo induced by vertebrobasilar arterial insufficiency.DESIGN: Case analysis.SETTING: Department of Neurology, Wuxi Second Hospital (Wuxi Municipal Second People's Hospital) Affiliated to Nanjing Medical University and Department of Neurology, Huaihua Hospital Affiliated to Nanhua University.PARTICIPANTS: A total of 57 patients, who were diagnosed as having episodic vertigo with or without nausea or vomiting, and hospitalized in the Department of Neurology, Huaihua Hospital Affiliated to Nanhua University from August 2003 to May 2004 and Wuxi Second Hospital (Wuxi Municipal Second People's Hospital) Affiliated to Nanjing Medical University between October 2004 and May 2005, were enrolled.METHODS: Fifty-seven patients with vertigo induced by vertebrobasilar arterial insufficiency hospitalized in the recent two years were treated with digital subtraction radiography in aortic arch and aortocranial angiography:Applying retrograde angiography of femoral artery puncture, Optiray nonionic contrast agent with syringe pattern to perform aortic arch angiography. Digital subtraction machine displayed bilateral carotid artery, vertebral artery, ranged from carotid artery to siphon of carotid artery from multiple angles. Measurement and evaluation were conducted by 2 doctors from department of neurology.MAIN OUTCOME MEASURES: Type, distribution and proportion of vesselstructural abnormity of aortic arch, carotid artery and vertebrobasilar system.RESULTS: Of the 57 patients, 1 patient was dropped out, because the left vertebral artery (LVA) could not be entered. A large area cerebral infarction was occurred in another patients during aortic arch angiography was performed, and the operation was stopped. Totally 55 patients were involved in the result analysis. It was found that 71%(39/55) of patients had vessel structural abnormity in cervical part and intracalvarium, 11%(6/55)of patients with simple anterior circulation lesion, 60% (33/55) of patients with posterior circulation lesion, of which 9 cases (16%) with compound lesion of anterior circulation abnormity. Two or above vessels in 24 cases (24/55,44%) were involved. Vertebral artery complicated with other angiostegnosis was the most common, and there was no vessel structural abnormity in other 16 cases (16/55,29%).CONCLUSION: Various types of vessel structural abnormity are the main etiological factors of vertigo induced by vertebrobasilar arterial insufficiency. Gold standard of diagnosing vertigo due to vertebrobasilar arterial insufficiency is DSA.

Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis (Mtb), is still one of the significant threats to human life. In recent years, the continuous exploration of small molecule inhibitors represented by bedaquinoline has brought new vitality into the field of tuberculosis. However, small molecule inhibitors will inevitably occur acquired drug resistance during clinical medication. As a new pharmacological mechanism, targeted protein degradation (TPD) achieves efficacy by destroying rather than inhibiting protein targets. It might be an excellent strategy to develop anti-tuberculosis drugs based on the TPD concept to solve drug resistance. This article reviews the protein degradation pathways of Mtb, such as the Pup proteasome system and the ClpP-ClpC1 complex enzyme system. The future development of these strategies into TPD drugs was prospected and summarized.

Objective To investigate the acute toxicity, subacute toxicity, nasal membrane local toxicity of the Magnolia biondii Pamp volatile oil nanometer bangosome. Methods Kunming mice and SD rats were selected as experimental material. Kunming mice were used in the acute and subacute toxicity tests by intragastric administration of Magnolia biondii Pamp volatile oil nanometer bangosome with different dosage and different time, and SD rats were used in the nasal membrane local toxicity test by nose dropping, while the control group was treated with intragastric administration of or nose dropping with normal saline for the same dosage. The treatment course lasted fifteen days. At the end of the tests, the general condition, routine blood test, function index of live and kidney, organ humid weight index, histological changes of liver and kidney and ultra microstructure change of rat nasal membrane were obtained and compared with the control group. Results In the acute toxicity test, the daily maximum tolerant dosage by intragastric administration was equal to 222.7 times of the clinical routine, with no marked toxic reaction. In the subacute toxicity test, the general condition, blood test, organ humid weight index and histological changes of live and kidney in different dosage groups were similar to the control group. While in the function index of live and kidney, uric acid was stepped down in the middle and large dose groups, and total bilirubin was decreased in the large dose group. The nasal membrane local toxicity test revealed that there was little change in the ultra microstructure of rat nasal membrane.Conclusion The Magnolia biondii Pamp volatile oil nanometer bangosome may have little toxicity by intragastric administration and nose dropping.

Dao-di Herbs is specificity and locality, and its unique phenotypic features is closely related to the growth and development of medicinal plants. In addition to traditional genetic, epigenetic play an important role in formation of Dao-di herbs. This paper introduces the concept of epigenetic and the role of DNA methylation in the gene expression regulation. We further prospects epigenetic mechanism in study of Dao-di herbs formation from specific phenotype and regional analysis. And study on the relationship of epigenetic and Dao-di herbs will provide a basis for quality assessment and identification of Chinese drugs.
