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.

Objective　This study was to investigate the Chlamydia trachomatis (CT) infection rate in cervical secretion of early pregnant and secondary sterility women. Method　CT-DNA in the cervical secretion of the early pregnant, the secondary sterility, and the control women was detected with polymerase chain reaction (PCR). Results　The infection rates of CT in the early pregnant and secondary sterility women （14.28% and 13.33%）were higher than in the control women (3.33%, P<0.05),and there was no significant difference between the former two groups (P>0.05). Conclusion　There are higher infection rates in the early pregnant and secondary sterility women.Detecting CT and treating in the perinatal period are needed in the early pregnant women who want to be pregnant again.

Objective To evaluate the effects of soybean protein and animal protein on renal function of patients with diabetic nephropathy.Methods In this Meta-analysis,literatures on the effects of soybean protein and animal protein on renal function of patients with diabetic nephropathy published during January 1980 and November 2011 were reviewed and analyzed quantitatively and synthetically by using Metaanalysis RevMan 5.0 software.Results Five case-control studies met the inclusive criteria and entered into random effect model.In comparison with animal protein,soybean protein significantly improved endogenous creatinine clearance rate (weight mean difference (WMD) =-11.51,95％ confidence interval (CI)-16.37 to 6.65),proteinuria (WMD =-0.96,95％ CI-1.36 to-0.58),urine creatinine (WMD =-1.11,95％ CI-1.91 to-0.30),glomerular filtration rate (WMD =0.28,95％ CI-0.12 to 0.68),serum urea nitrogen (WMD =-0.20,95％ CI-0.60 to 0.19) and serum creatinine (WMD =-0.22,95％ CI-0.54 to 0.10).Conclusions Soy protein seems to have potential to improve urine creatinine clearance,urine creatinine,proteinuria and serum urea nitrogen.However,animal protein may contribute to increased glomerular filtration rate.

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 explore the changes of estrogen receptor (ER) and progesterone receptor (PR) in the endometria of pro-liferative phase in polycystic ovary syndrome (PCOS) patients. Methods Thirty-two patients who suffered PCOS combined with infertilitas feminis were enrolled in this study, and 20 cases of tubal infertilitas feminis having the corresponding time period were selected as controls. The expressions of estrogen receptor (ER) and progesterone receptor (PR) in the endometria were observed by pathological examination and immunohistochemical staining. Results The expressions of ER and PR in the PCOS group in the glands and interstitium of endometrial a-mong three different periods were not significantly different. The expressions of ER and PR in the glands and interstitium of endometrial a-mong three different periods in the control group were significantly different. There was no statistical difference in the expressions of ER, PR in the glands and interstitium of the early endometria between PCOS group and control group. The expressions of ER in the glands and inter-stitium of the middle endometrial in PCOS group was significantly lower than that of control group. The expressions of ER and PR in the glands and interstitium of the late proliferative endometrial in PCOS group was significantly lower than that of control group. Conclusion ER and PR of endometrial in the PCOS patients decreased. The cyclical of ER and PR in the PCOS patient were irregular.
