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.

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.

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.

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　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 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.

Objective To screening up-regulated protein kinases and their inhibitors in order to provide new targets for molecular thera-py of nasopharyngeal cancer.Methods GEO database and SAM software were employed to screen the up-regulated protein kinase gene in nasopharyngeal cancer.Based on DAVID database,the regulating functions of kinases were identified.The inhibitors of up-regulated kinase genes were identified by Selleckchem database.Literature mining was used to screen the potential anti-cancer drugs.Results Totally 2360 differentially expressed genes including 21 up-regulated protein kinases (CHEK1,CHEK2,PRKDC,AURKA,VRK2,STK17A,MELK,NU-AK1,TRPM7,MASTL,AXL,BUB1,BUB1B,CDK4,TTK,CDC7,CASK,AKT3,TBK1 and PBK)were identified in the whole genome profi-ling (Fold Change≥2,P <0.05).The results of function analysis showed the up-regulated genes were enriched in 10 function terms such as‘protein amino acid phosphorylation’‘phosphorylation’‘phosphate metabolic process’‘mitotic cell cycle’‘cell cycle phase’‘regulation of cell cycle’,and so on.The Selleckchem database analysis showed there were 9 up-regulated protein kinases equipped with 51 inhibitors which were proved already.The results of literature mining showed that 18 inhibitors of them had a few studies (less than 10 literatures)in cancer terms,and there was a potential to become new drugs to treat nasopharyngeal cancer.Conclusion A total of 21 up-regulated protein kinases were identified,and they might promote the nasopharyngeal carcinoma by regulating functions such as the cell-cycle control pathway.Their ki-nase inhibitors may have a potential role in anti-cancer treatment,which provided a new target point for molecular therapy of nasopharyngeal cancer.
