To understand Lophatherum gracile plant community's structural characteristics, a survey of community structure and species diversity was conducted through quadrat sampling in Yongchuan district of Chongqing. The results showed that there were 386 species vascular plants, belonging to 117 families and 229 genera. Based on habitat, community structure and species composition, L. gracile were found in three community types: Pinus massoniana community, banboo community, shurb community. Vertical structure was composed of three layers, including tree layer, shrub layer and herb layer. Species in shrub layer was the richness. P. massoniana is the only dominant species of the community, it can not regenerate naturally, the shrub layer has a greater effect on the community of L. gracile in the future. In addition, the banboo community and shurb community is not stable because of human's activity. Therefore, the community characters of L. gracile should be taken care of conservation when the resources are utilized.

OBJECTIVETo observe effects of treatment from the lung and treatment from the intestine on the level of vasoactive intestinal peptide (VIP) in the lung and intestine of ulcerative colitis (UC) rats.
METHODSThe UC rat model was established in 52 rats by using rabbit intestine mucosa tissue allergen combined TNBS-ethanol model (with the model successful rate of 78.0%). Eight rats randomly selected from 40 successfully modeled rats and 8 of 16 rats from the normal group were recruited as the model group and the normal control group before intervention (at week 0). The rest 32 successfully modeled rats were randomly divided into the model group, the Western medicine treatment group (salazosulfapyridine), the treatment from lung group (Huangqi Jiegeng Decoction), and the treatment from intestine group (Huangqi Huanglian Decoction), 8 in each group. Rats in each treatment group were administered with corresponding medication 8 times the dose of a 60 kg adult human. Another 8 normal rats were recruited as the normal group. Equal volume of pure water was given to rats in the model group and the normal group by gastrog avage, once per day. Contents of VIP in the lung tissue and the intestinal tissue were detected at week 0 and 4 after 4-week consecutive intervention. Pathomorphological changes of the lung tissue and the colon tissue were observed under light microscope.
RESULTSCompared with the normal control group at week 0, evenly distributed diffuse inflammation could be seen in the pulmonary interstitial tissue; the bronchial wall was thickened; a huge amount of infiltration surrounded bronchi and blood vessels; a large area of necrosis of intestinal mucosa and inflammatory cell infiltration could also be seen in the model group. Pathological injuries of the lung and the colon were more alleviated in each treatment group than in the model group at the same time point. Compared with the normal control group at the same time point, VIP contents in the lung tissue significantly decreased in the model group at the end of week 4 (P<0.05); VIP contents in the colon tissue significantly increased in the model group at the end of week 0 and 4 (P <0.05). Compared with the model group, VIP contents in the lung tissue significantly increased in the Western medicine treatment group and the treatment from lung group at the end of week 4 (P<0.01); VIP contents in the colon tissue significantly decreased in the treatment from lung group and the treatment from intestine group (P<0.05, P<0.01).
CONCLUSIONTreatment from the lung and treatment from the intestine showed predominant advantage in improving local inflammation of the lung and the intestinal tract, alleviating pathological injuries, promoting repair of injuries through regulating VIP contents in the lung tissue and the colon tissue.

Abstract: Objective By collecting and sorting the information of varicella cases reported in Liaoning Province from 2006 to 2021, the epidemiological characteristics were analyzed, and the monthly incidence data were predicted, so as to explore the prevention and control strategy of varicella disease in Liaoning Province. Methods By collecting the characteristic information of varicella cases in Liaoning Province, epidemiological analysis was carried out on the regional, population, and temporal characteristics of varicella incidence. The monthly incidence data of varicella were fitted with Eviews software, seasonal ARIMA model was used for modeling, and models were selected according to SC and AIC. After modeling, the model was used to predict the incidence data in 2022. Results The incidence rate of varicella in Liaoning Province has increased in recent years. The onset time was "bimodal distribution", with the main peak occurring from November to January of the next year and the secondary peak occurring from May to June. Since 2019, the onset age has shifted backward. From the original 0-<10 age group with the highest incidence rate, it shifted to the 10-<20 age group with the highest incidence rate. From 2006 to 2021, the incidence of varicella mainly concentrated in people aged 0 to <40 years old, and the incidence rate of the population over 40 years old showed a cliff-like decline. The incidence of chickenpox was higher in the central region of Liaoning Province, such as Shenyang, Dalian, Anshan and Panjin, and relatively low in Huludao, Jinzhou, Fuxin and Liaoyang. The distribution of the population was mainly students, followed by kindergartens and scattered children. ARIMA model of monthly incidence data was established by software as ARIMA (1, 0, 1) (1, 1, 1)12. Conclusions The incidence rate of varicella in Liaoning Province has been rising in recent years. The incidence is obviously seasonal, and the age group of the affected population has moved backward. It is predicted that the incidence will continue to increase in 2022. The prevention and control of varicella should still be the current key work. In order to reduce the population incidence rate, two-dose vaccination strategies should be vigorously promoted the implementation of the, and the inclusion of varicella vaccine in the immunization program should be achieved as soon as possible.
