Objective To study the efficacy of the electrolyzed oxidizing water (EOW) in the oral irrigation of patients with oral trachea cannula. Methods 60 patients with oral trachea cannula were ran-domly divided into the experimental group and the control group, the experimental group received oral irri-gation with EOW,while the control group used normal saline. The oral irrigation efficacy was compared be-tween the two groups. Results In the experimental group,the bacterial clearance rate was 95.21% ,while the control one's was 37.19%, the stomatodysodia rate of the experimental group was 3.33%, the control one's was 86.60%, the oral fungus infection rate of the experimental group was 0% , the control one's was 43.33%, the incidence of dental ulcer of the experimental group was 10.00%, the control one's was 3.33%. Significant difference existed in bacterial clearance rate and the stomatedysodia rate between the two groups. Conclusions Oral irrigation with EOW in oral trachea cannula patients can decrease or con-trol the field planting of bacterium in pharynx oralis and stomatodysodia, and prevent pulmonary infection.

Baby body plethysmography is a well-established technique of lung function determination,which is widely used to access the respiratory development and obstructive airway diseases by precisely measuring tidal breathing,functional residual capacity,and air way resistance.Babies who accept lung function measurements in the baby body plethysmography are under quiet state of spontaneous breathing without any subjective initiative,which results in multiplexed data acquisition,high precision and good repeatability.Clinical application of baby body plethysmography differs in different countries and areas,with the most intensive application in the German-speaking countries.In China,the clinical use of baby body plethysmography still remains in primary stage.Great progress has been achieved in its clinical use during the past 20 years,but there is still a lack of consensus on normal reference values or equations with which to interpret results,which has caused some trouble to diagnosis and identification of respiratory disease.In order to identify the nature and severity of airway disease,it is essential to understand the normal range of plethysmographic values that may occur in healthy infants of similar age,gender and body size.

BACKGROUND: The characteristics of laminin that can promote the proliferation of stem cells have been widely concerned. OBJECTIVE: To review the interactions between laminin and many different stem cells, and provide reliable theoretical basis for chondrogenic research and application of stem cells. METHODS: Wanfang, CNKI, PubMed and Web of Science databases were searched for articles related to mechanism of laminin, changes in stem cell behaviors, and cartilage regeneration published from January 2010 to October 2019. The retrieval terms were “laminin” and “steam cells” in Chinese and English. Duplicated and poorly related articles were excluded, and finally 57 articles were included for review. RESULTS AND CONCLUSION: (1) The structural characteristics of laminin were summarized. The spatiotemporal changes of laminin during cartilage development and degradation were analyzed. At the same time, the distribution of laminin expression in natural cartilage tissue and tissue engineered cartilage tissue was compared. (2) The effects of laminin on the proliferation of various stem cells, including embryonic stem cells, induced pluripotent stem cells and adult stem cells, were described. (3) The possible hotspots on the combination of laminin and stem cells for cartilage regeneration were proposed, with the attempt of providing theoretical basis for cartilage repair and regeneration in the future.

At the urgent request of Artemisia annua (ART) planting, the paper gets artemisinin content (ARTC) of ART in China from literatures. The paper analyses the relationships between ARTC and ecological factors by statistical analytical methods. The paper also analyses the climate suitable rank distribution of ARTC in China by ArcGIS. The results display that first, ARTC is significantly different in China, that ART from the south regions ARTC is higher. Greatest north parts of China have not suitable climate for the growing of ART and the ARTC is lower than 0.2%, when ART grows above the 34th degree of northern latitude. ARTC is higher and ART grows well, when ART grows under the 34 degrees N and grows at the areas between 100 degrees E and 120 degrees E. Second, subtropical zone is the best suitable climate zone for the growing of ART. ART grows well and ARTC is higher than 0.5%, when ART grows in the subtropical zone. Third, temperature, sunshine duration and rainfall are the main ecological factors that affect the growth of ART and the accumulation of ARTC. That the year temperature between 13.9 degrees C and 22 degrees C, sunshine duration between 853 h and 1507 h, rainfall between 814 mm and 1518 mm, is the best climate for the accumulation of ARTC. Temperature between 13 degrees C and 29 degrees C, rainfall between 600 mm and 1300 mm is the best climate for the growth of ART. Fourth, in northwest of Guangxi, eastern of Sichuan, Guizhou and Yunnan provinces, south Chongqing and west Hunan Province, there are suitable climate for the growth of Artemisia and for the accumulating of ARTC. There are also some suitable climate areas for the growing of artemisia in the south of Hubei, Anhui and Jiangsu provinces.

AIM: This paper, starting from the perspective of "human beings' living world", tries to reveal the historical epoch premise of mental health and redefines the criteria of mental health by "harmonization of human beings'relationships".METHODS: Sorting out the criteria of mental health by studying a large numbers of literatures.RESULTS: Four kinds of harmonious relationships in human beings' living world are disclosed, namely, the symbiosis of man and nature, the interaction between man and man, the integration of human beings and their egos, and the signification of mental health by inosculating man and "god".CONCLUSION: Grasping the real philosophical connotation of mental health to focus on human beings' realistic life quality through "the fashion of man".

[Objective]To report the treatment and outcome of treatment of discoid lateral meniscal tear by arthroscopic surgery.[Method]During the period between Jan.1999 and Jun.2005,77 patients suffered from discoid lateral meniscal tear have been treated by arthroscopic surgery in Xijing Hospital. The standard arthroscopic portals (anteromedial and anterolateral)were used.Lateral menisci were totally removed in the 21 patients (29.2%) of total 77 cases,whereas lateral menisci of 13 patients (18.1%) were removed partially and meniscus-plasty was applied in 38 patients (52.8%).Thirty-nine (54.2%) of 77 patients were males,and 33 (45.8%) females.Their average age was 29.4?10.9 years (range 8~51 year).Five patients were lost in follow-up.The mean follow-up period of the rest 72 patients was 26.2 ?9.3 months (range 12~44 months).The patients were assessed pre-operationally and post-operationally by the Lysholm score.Moreover,the results of Lysholm score were analyzed by student-t test.[Result]All patients had progress in pain,swelling,range of motion and knee function. No complication,which included intraarticular infection,iatrogenic injury,fibroarthritis or loss of range of motion,was found.Lysholm score was 66.8?5.2 in average (range from 50 to 78) before operation,whereas it improved to 96.4?3.6 in average (range from 85 to 100) after operation.According to student-t analysis,very significant statistical difference was found between the pre-operative and post-operative results (t=34.7,P
