The clinical symptoms of functional constipation in the elderly are more unique which represents as over concern about their bowel movement,excessive straining and worse feelings to the constipation.The intestinal physiological function declining with age,reductions of enteric neurons and interstitial cells of Cajal,neuronal degeneration and injured contractibility of intestinal smooth cells are enrolled in the pathogenesis of functional constipation.More attention should be paid to drug interactions and adverse effects in clinical practice due to more underlying disease and concomitant medication in the elderly.

BACKGROUND: Brain tissue is the most complex structure of human development. Many human brain diseases are difficult to reproduce in animals, so the establishment of an in vitro model of brain development has a very important research value. In recent years, with the rapid development of the field of stem cells, an artificial tissue culture technology has emerged, that is, through the three-dimensional culture in vitro, stem cells from a single cell are produced into a complex structure resembling whole organs, which is called organoids. OBJECTIVE: To review the research progress of brain organ in recent years from the aspects of the current situation of brain organ culture, pathogenesis, histological characteristics and application in nervous system diseases, and analyze the research defects of brain organ in order to provide reference for the research in related fields. METHODS: CNKI, Wanfang, and PubMed databases were searched by the first author for related studies published from January 1998 to June 2019. The keywords were “organoids, cerebral organoids, embryonic stem cells, induced pluripotent stem cells, neurogenesis, cerebral cortex, development, neurodegenerative disease” in Chinese, and “organoids, cerebral organoids, embryonic stem cells, induced pluripotent stem cells, neurogenesis, cerebral cortex, development, neurological diseases, self-organization” in English. Finally, 45 eligible articles were included in result analysis. RESULTS AND CONCLUSION: The cerebral organoids can be effectively developed in vitro by using the self-organization of pluripotent stem cells and adding nerve-inducing factors. As a new biological culture technology, cerebral organoids have great research and application value in investigating development of living tissue, the mechanism of disease formation, tissue replacement therapy and drug experiments.

Objective:To analyse the methord and effects of intermaxillary traction(IMT)screws used in the treatment of jaw frac-ture.Methods:In the treatment of 1 68 cases of jaw fracture IMT screws were used for the restoration of normal and stable occlusion. The screw number,position,traction effect and postoperative complications of the treatment were analysed.Results:705 screws were used in 168 patients,4 screws were used in each of 147 cased (88%),6 in 12(7%),5 in 9(5%).336(47.7%)screws were fixed between the roots of first and second premolar,292(41 .4%)between the roots of canine and first premolar,50 (7.1%)be-tween the roots of second premolar and first molar,27(3.8%)between the other tooth roots.Normal postoperative occlusion relation was achived by the use of screws in 92 cases without traction.Occlusion disharmony or deviation was found in 76 cases by the used of screws and was restored to normlal by 1 4-day traction in 71 cases.The total efficiency of the treatment was 97%.Pain of the mucosa surrounding the screws was observed in 23 cases (1 3.7%).Root damage,traction screw loosening and adjacent tooth dislocation were observed in 1 3(1 .8%),1 1 (1 .6%)and 2(0.3%)cases respectively.Conclusion:For the fixation of IMT screws,the posi-tions between tooth root from canine to first molar were most common and safe.The fixation point should be in 5 ~8mm below the gin-gival margin.Use of 4-6 screws can meet treatment need.

Objective To investigate the prevalence and risk factors of chronic kidney disease(CKD)in the adult population receiving healthy examination from Xinjiang. Methods A total of 10 025 subjects who were older than 20 years and received healthy examination in Health Center of the First Affiliated Hospital,Xinjiang Medical University,from January 2009 to April 2010 were enrolled. Results The prevalence of proteinuria was 4.86%(95%CI:4.44%-5.28%),hematuria 3.13%(95%CI:2.79%-3.47%),and reduced eGFR 2.66%(95%CI:2.34%-2.98%).Approximately 9.60%(95%CI:9.02%-10.18%)of these subjects had at least one indicator of kidney damage.Albuminuria was independently associated with male,systolic blood pressure,BMI,glycometabolism abnormity, hypertriglyceridemia.Hematuria was independently associated with female,minority,aystolic blood pressure.Reduced eGFR was independently associated with female,age,obesity,hyperlipidemia,hyperuricemia.Age,gender,glycometabolism abnormity,systolic blood pressure,hyperuricemia and hyperlipidemia were independently correlated with CKD. Conclusions The prevalence of chronic kidney disease is 9.60%in the adult population receiving healthy examination,which is quite high and should be considered.The spectrum and correlated factors of CKD in this population are similar to studies reported.

Objective In order to investigate the influence of reelin deficiency on the hippocampal development, the histochemical characteristics of hippocampal pyramidal cells and granule cells of reeler mice were analyzed, therefore, reelin's function would be better understood with more morphological evidences. Methods With immunofluorescent double labeling, the pyramidal cells, granule cells and mossy cells in hippocampi between wild type and reeler mice were labeled. Results The development and lamination of hippocampal cortical plate were in disorder. Pyramidal cells and granule cells dispersed, and moreover, granule cells proliferated rapidly and migrated into hilus, so that the bound between granule layer and hilus disappeared. Conclusion As a stop signal and regulatory signal, reelin plays important roles in neuronal migration of developing cortical plate, especially in the regulation of granule cell proliferation.
