It is believed that the root cause of vascular dementia lies in insufficient primal yang and weakness in the circulation of blood. The key pathological factors are the mutual stagnation of phlegm and blood stasis， and the obstruction of blood vessels. The general treatment principle is to tonify qi and promote yang， expel pathogenic factors， and unblock yang. This involves supplementing the innate and acquired yang qi of the spleen and kidneys， removing pathogenic factors like phlegm， turbidity， and blood stasis， in order to restore the function of yang qi and promote the circulation of blood and qi. The basic prescription for tonifying qi and promoting yang includes Heishunpian （Lycium Ruthenicum）， Zhichuanwu （Aconitum Carmichaelii）， Guizhi （Cinnamomum Cassia）， Renshen （Panax Ginseng）， and Huangqi （Astragalus Membranaceus）. Depending on the type of pathogenic excess， the treatment can be modified with Tongqiao Huoxue Decoction （通窍活血汤）， adding Yujin （Curcuma Longa） and Xiangfu （Cyperus Rotundus） to invigorate blood and promote yang， or with Fabanxia （Pinellia Ternata）， Chenpi （Citrus Reticulata）， Zhishi （Citrus Aurantium） plus Sijunzi Decoction （四君子汤） to resolve phlegm and promote yang. Both the root and branch are treated simultaneously. When yang qi is activated， blood and qi are nourished， and when pathogenic excess is expelled， the blood vessels are unblocked. This approach aims to provide a treatment strategy for vascular dementia.

In this study， bibliometric methods were used to systematically investigate the name and origin， the evolution of prescription composition， dose evolution， origin and processing method， decoction method， ancient application， modified application， modern application and other information of Huoxiang Zhengqisan. After research， Huoxiang Zhengqisan， also known as Huoxiang Zhengqitang， was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium， 41.3 g of Angelicae Dahuricae Radix， 41.3 g of Perilla frutescens（actually Perillae Folium）， 41.3 g of Poria， 82.6 g of Pinelliae Rhizoma， 82.6 g of Atractylodis Macrocephalae Rhizoma， 82.6 g of Citri Reticulatae Pericarpium（actually Citri Exocarpium Rubbum）， 82.6 g of Magnoliae Officinalis Cortex， 82.6 g of Platycodonis Radix， 123.9 g of Pogostemonis Herba， and 103.25 g of Glycyrrhizae Radix et Rhizoma. In this formula， Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products， Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products， and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose， take 8.26 g of the powdered formula， add 300 mL of water， along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus， and decoct until reduced to 140 mL. The decoction should be administered hot， with three times daily. To induce sweating， the patient should be kept warm under a quilt， and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness， regulate Qi and harmonize the middle， which is mainly used to treat a series of diseases of digestive and respiratory systems. However， potential adverse reactions， including allergies， purpura and disulfiram-like reactions， should be considered during clinical use.

Lianggesan was first recorded in Taiping Huimin Heji Jufang， which was composed of Rhei Radix et Rhizoma， Natrii Sulfas， Gardeniae Fructus， Forsythiae Fructus， Scutellariae Radix， Glycyrrhizae Radix et Rhizoma（GRR）， Menthae Haplocalycis Herba， Lophatheri Herba and Mel. It was clinically applied to treat fire-heat syndrome in the upper and middle Jiao， and the curative effect was positive. In this study， the bibliometric method was used to conduct a detailed textual research on the formula name， medicinal composition， dosage evolution， origin and processing， functional indications and other aspects of Lianggesan. Research revealed that Lianggesan has six other names， such as Lianqiao Yinzi， Lianqiao Jiedusan， Jufang Lianggesan， Jiegu Lianggesan， Hejian Lianggesan and Qingji Lianggesan. Based on the edition of Taiping Huimin Heji Jufang， an analysis of the evolution of its formula composition revealed that the missing Chinese medicines were predominantly bamboo leaves and honey， while the added Chinese medicines were primarily supplements introduced to address changes in disease manifestations. After textual research， the dosage for one dose of Lianggesan from Taiping Huimin Heji Jufang was as follows：826 g of Rhei Radix et Rhizoma， 826 g of Natrii Sulfas， 826 g of GRR， 413 g of Gardeniae Fructus， 413 g of Menthae Haplocalycis Herba， 413 g of Scutellariae Radix， and 1652 g of Forsythiae Fructus. Decocting method was as following：Grinding the Chinese medicines into coarse powder（2-4 mm）， taking 8.16 g per dose， adding 300 mL of water， along with 2 g of Lophatheri Herba and 5 g of Mel， and decocting to 140 mL. The residue was removed and taken warmly 30 min after meals. It was recommended to take it three times daily until improvement was achieved. The origins of the 9 Chinese medicines were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. Except for GRR， which required single frying（stir-frying）， the remaining medicines were all raw products. The description of the function of this formula in ancient books was summarized as purging fire and promoting bowel movements， clearing heat from the upper body and purging the lower body， and the main syndromes included facial redness， tongue swelling， red eyes， etc. In modern applications， the formula is primarily used for respiratory and digestive system diseases， including acute lung injury， chronic obstructive pulmonary disease， herpetic angina and aphthous stomatitis， covering 142 types of diseases. In summary， this paper can provide a basis for further research and development of Lianggesan through the literature review and key information combing.

Objective:To learn about the characteristics of natural foci and the spatial distribution of mosquitoes and ticks in Yadong County, Tibet Autonomous Region (Tibet for short).Methods:The eco-geographical characteristics, demographic information, agricultural and animal husbandry data of the natural foci in Yadong County, Tibet were collected from the Yadong County 2020 statistical yearbook, vector data were collected from the Yadong County Center for Disease Control and Prevention, and the data of the meteorological station in Yadong County from 2010 to 2021 were collected from the World Weather Network. In July 2021, a total of 20 mosquito and tick sampling points were selected for field investigation according to the distribution characteristics of vegetation and animal husbandry of Yadong County. The light trap method was used to trap mosquitoes, and the manual inspection and flag dragging method were used to catch ticks. The spatial distribution characteristics of mosquitoes and ticks were analyzed.Results:The natural epidemic foci in Yadong County, Tibet, were high in the north and low in the south, with an elevation difference of about 5 000 m. It was rich in water resources, and the average runoff of Yadong River was 20.1 m 3/s. The climate in the north was cold and dry, and the south was mild and humid. From 2010 to 2021, the annual average station air pressure in Yadong County was 452.8 mmHg (1 mmHg = 0.133 kPa), the maximum monthly average temperature, precipitation and relative humidity of air were 8.7 ℃, 134.5 mm and 81.3%, respectively, all in July. A total of 6 897 diptera insects were attracted by the light trap method, all of which were non-blood-sucking mosquitoes. The total density was 163.77 pieces/(lamp·h), the dominant population was Muscaridae, accounting for 89.69% (6 186/6 897). In different sampling areas, Xiayadong Township collected the most mosquitoes, accounting for 67.17% (4 633/6 897); the others were Yadong County and Shangyadong Township, accounting for 27.36% (1 887/6 897) and 5.47% (377/6 897), respectively. A total 2 014 host animals were examined, and 23 parasitic ticks were caught, of which 20 were of the genus Ixodes and 3 were of the genus Haemophilus. No free ticks were caught in all ticks sampling points. Conclusions:The climate and ecological environment of the natural foci in Yadong County, Tibet have obvious vertical gradient. Mosquitoes and ticks are active, but the density is not high, the density of mosquitoes is generally high in the south and low in the north.
