Objective To investigate the operative methods and merits of nasal reconstruction in terms of the aesthetics. Methods The noses of 12 patients were reconstructed with an expanded triangle-shaped forehead flap with unilateral supratrochlear artery, a skin expander was placed obliquely under galea aponeurotica of forehead. Liquid was injected with conventional expansion method. Using the skin and the scars on nasal dorsum and tip as lining, based on intercanthal distance and aesthetic standard, a triangle-shaped forehead myocutaneous flap was designed over the expanded forehead skin tissue and used for a nasal reconstruction. The triangle-shaped flap was trimmed to different layer and reshaped based on aesthetic subunit.Results In twelve post-operative patients with nasal defect, no flap necrosis was found and the appearance of reconstructed noses were almost normal and satisfactory after follow-up for 6 months to 2 years. Conclusion The modified forehead myocutaneous flap according to aesthetic standard is safe and ideal for major nasal reconstruction. Meticulous moulding of triangle-shaped flap, nose interior with good blood supply, and primary insertion of nose stretcher are the key to a satisfactory appearance.

Xiang thinking is the key way of thinking to construct the life model of human body in traditional Chinese medicine （TCM）， and the theory of ascending and descending of qi movement is an important manifestation of xiang thinking in the theory of TCM. Based on the theory of qi movement， this paper interpreted the mechanism of ischemic stroke through the perspective of xiang thinking "earth weakness - wood constraint - fire hyperactivity"， as "earth weakness in the central and dampness accumulated to phlegm" "wood constraint and stirring wind led to blood stasis" and "fire hyperactivity and fire toxin showed flaming upward" due to disorder of qi movement. Combined with the "xiang of medicinal properties and therapy methods" to discuss the treatment and prescriptions of ischaemic stroke， applying wind medicinals to elevate ji-earth （己土） and yi-wood （乙木）， so that phlegm and stasis can be eliminated， and cold medicinals to descend jia-wood （甲木） and wu-earth （戊土） so that fire toxin can be cleared， with a view to restore ascending and descending of qi movement for ischaemic stroke.

This paper summarized the clinical experience in treating ischemic stroke with jiao （角） medicine （triple-medicinal combinations）. Clinically， the combination of Roucongrong （Cistanche deserticola）-Shanyurou （Cornus officinalis）-Guijia （Testudinis Carapax et Plastrum） is used to nourish the kidneys and liver for disease mechanism of liver-kidney depletion， and foundation deficiency due to insufficient essence and blood； the combination of Xixiancao （Sigesbeckia orientalis）-Tianma （Gastrodia elata）-Gouteng （Uncaria rhynchophylla） is used to extinguish wind and eliminate dampness for treating numbness and swelling of limbs caused by ischemic stroke； the combination of Shichangpu （Acorus Tatarinowii）-Yuanzhi （Polygala tenuifolia）-Yujin （Curcumae Radix） is used to improve intelligence， refresh the brain， and clear the mind for treating cognitive impairment， memory loss， or speech difficulties caused by ischemic stroke； the combination of Banxia （Pinellia ternata）-Baizhu （Atractylodes macrocephala）- Tianma （Gastrodiae rhizoma） is used to dissolve phlegm and extinguish wind， unblock meridians and relieve dizziness for treating dizziness or headache caused by ischemic stroke； the combination of Danggui （Angelica sinensis radix）- Chuanxiong （Ligusticum chuanxiong）-Guijianyu （Euonymus alatus） is used to nourish and activate blood circulation， remove blood stasis and unblock meridians for treating weak limbs and activiry difficulty caused by ischemic stroke； the combination of Chaihu （Bupleurum chinense）-Zhiziz （Gardenia jasminoides）-Guanye Jinsitao （Hypericum perforatum） is used to soothe the liver and resolve constraint， cool the blood and calm the mind for treating emotional complications.

As the guiding theory for the diagnosis and treatment of encephalopathy in traditional Chinese medicine （TCM）， The marrow sea theory has important theoretical connotation and clinical value. This paper summarized the clinical research literature on the differentiation and treatment of common encephalopathy based on the marrow sea theory published in recent years， analyzed the treatment method and effects from eight aspects in terms of stroke， dizziness， insomnia， headache， constraint syndrome， dementia， tremor syndrome， and atrophy syndrome， and discussed the possible mechanism based on the relevant basic research. It is believed that marrow sea depletion is the common pathogenesis of encephalopathy in TCM. Guided by the method of supplementing essence and boosting marrow， the corresponding formulas and medicinals are recommended in accordance with differentiated syndromes， which can effectively improve the symptoms of the disease， delay the progression， increase the daily life ability of the patients， and improve the quality of life. Based on the marrow sea theory， the method of supplementing essence and boosting marrow， rectifying healthy qi and dispelling pathogen can be used to highlight the advantages of TCM and provide ideas for the diagnosis and treatment of encephalopathy in TCM.

This paper summarized the experience of Professor FANG Dingya in staged treatment of Sjögren's syndrome from the perspective of dryness toxin. It is believed that the cause of Sjögren's syndrome is externally-contracted dryness， consumption of essence and fluid， congenital and acquired essence deficiency， depleted essence and insufficient blood， and the core mechanism is internal accumulation of dryness toxin. The treatment can be divided into three stages， that is dryness toxin transforming into fire-heat， damp-heat and phlegm-stasis， from the perspective of dryness metal qi transformation. It is emphasized to dispel pathogen mainly， to clear and moisten with yin-nourishing medicinals in supplementation， and to treat by stages based on syndrome differentiation. For dryness toxin with fire-heat， it is suggested to moisten dryness， resolve toxins and subdue fire， with self-made Runzao Jiedu Decoction （润燥解毒汤） in modification. For dryness toxin with damp-heat， the method of nourishing yin， clearing heat and draining dampness should be used， and Chunze Decoction （春泽汤） in modification is suggested. For dryness toxin with phlegm-stasis， it is recommended to unblock collaterals， disperse phlegm and dissipate stasis， with self-made Sanyu Xiaotan Decoction （散瘀消痰汤） in modification.

This paper summarized the clinical experience of XU Fengqin in the treatment of hypertension in the elderly. It is believed that the basic pathogenesis of hypertension in the elderly is liver and kidney depletion， and the key is ascendant hyperactivity of liver yang and spleen failing to transport. Therefore， the theory of “combination of disease and symptoms” is put forward that the four common clinical symptoms of hypertension in the elderly， including morning hypertension， non-dipper hypertension with abnormal circadian rhythm， postprandial hypotension and orthostatic hypotension， should be differentiated and treated with prescription in accordance with the characteristics of the corresponding pathogenesis. Specifically， the pathogenesis of morning hypertension is mainly liver-kidney yin deficiency and ascendant hyperactivity of liver yang， for which the treatment method of enriching liver and boosting kidney， calming the liver and subduing yang is suggested， and Qingxuan Jiangya Decoction （清眩降压汤） in modifications can be used. For non-dipper hypertension with abnormal circadian rhythm， the pathogenesis is mainly phlegm-dampness obstruction and clear yang failing to ascend， and treatment method should be dissolving phlegm and dispelling dampness， calming the liver and extinguishing wind， with Banxia Baizhu Tianma Decoction and Modified Honglong Xiahai Decoction （半夏白术天麻汤合加味红龙夏海汤） in its modifications. Regarding postprandial hypotension and orthostatic hypotension， the pathogenesis is mainly spleen-stomach depletion and clear yang failing to ascend， and thus the method of supplementing the center and boosting qi， raising yang and lifting the sunken is advised with Buzhong Yiqi Decoction （补中益气汤） or Yiqi Congming Decoction （益气聪明汤） in the modifications.

With increasing aging， cognitive impairment in elderly coronary heart disease is a "disease group" with high morbidity and mortality in the senior population， which seriously affects the health and quality of life of the elderly. This paper takes the "cardio-cerebral circuit" as the basis of co-morbidity， and under the guidance of the cardio-cerebral homoeopathy， based on the temporal sequential characteristics of the evolution of the disease mechanism of cognitive impairment in elderly coronary heart disease， we construct a “disease-syndrome-phase” prevention and treatment strategy based on the time-sequential characteristics of the pathogenesis of the disease mechanism of "deficiency-blood stasis-toxicity"， from the perspective of pathogenicity of the disease mechanism in time-phase and the spatial multidimensionality of cardio-cerebral homoeopathy. The prevention and treatment strategy of the "disease-syndrome-phase" is constructed from the perspective of the temporal phase of the disease mechanism and the multidimensionality of the space of cardio-cerebral homoeopathy. In the earlier stage， "kidney deficiency and brain emptiness are the foundation"， in the attack stage， "turbid stasis and brain injury are the key"， and in the progression stage， "toxicity and brain damage are the changes". It is emphasized that replenishing the deficiency and benefiting the kidneys to restore the smooth flow of collaterals， eliminating blood stasis and removing turbidity to promote the enrichment of blood， and detoxifying and clearing the heart to tranquilize the spirit and benefit the brain， the spatiotemporal thinking of cognitive impairment of coronary heart disease in the elderly is initially constructed with the spatial dimension to identify the location of the disease， and the temporal dimension to determine the stage of the disease， which will provide a theoretical basis for the spatiotemporal diagnostic and treatments for the heart and brain co-morbidities of TCM.
