Using the method of stem cells transplantation to treat the spinal cord injury is one of the hotspots of spinal cord injury repair research in recent years. OBJECTIVE:To summarize the progress and application prospects of stem celltransplantation in the treatment of spinal cord injury. METHODS:A computer-based search of PubMed and CNKI was retrieved for relevant articles concerning stem celltransplantation for treatment of spinal cord injury published after 2000. The keywords were“spinal cord injury, stem cell, celltherapy”in English and Chinese, respectively. Meta-analysis and secondary literature were excluded as wel as repetitive or old literature. Final y, 52 articles were included in result analysis. RESULTS AND CONCLUSION:This article summarizes types and biological characteristics of stem cells, basic mechanism, techniques and therapeutic efficacy of stem celltransplantation in the treatment of spinal cord injury, and proposes the issues and prospects concerning the stem cells transplantation for treatment of spinal cord injury.

Objective To investigate the risk factor profile of pneumonia caused by pandrug-resistant Acinetobacter baumannii (PDRAB)in intensive care unit for better distinction between PDRAB infection and colonization.Methods The clinical data of 99 patients diagnosed as A.baumannii pneumonia between February 2009 and March 2012 in Fangcun Hospital,a branch of Guangdong Provincial Hospital of Traditional Chinese Medicine,were reviewed and analyzed retrospectively.The risk factors associated with pandrug-resistance in A.baumannii were examined with multivariate logistic regression analysis.Results ICU stay,duration of invasive ventilation,longer duration of treatment with carbapenems,beta-lactam/beta-lactamase inhibitor,or quinolone antibiotics,use of ≥3 classes of antimicrobial agents,≥3 invasive procedures (including indwelling gastric canal, catheterization,central venous catheter,arterial sheath),and fiberoptic bronchoscopic treatment were associated with PDRAB pneumonia (P <0.05).Multivariate logistic regression analysis showed that use of ≥3 classes of antibiotics,fiberoptic bron-choscopic treatment,and longer duration of treatment with beta-lactam/beta-lactamase inhibitor were independent risk factors predicting the emergence of PDRAB pneumonia.Conclusions We should pay more attention to these risk factors in clinical prac-tice for better differentiation between PDRAB infection and colonization so that appropriate control measures can be taken pro-actively.

Objective:It is more difficult to conduct precision radiotherapy for organs of the human body with the respiratory movement. It is necessary to compensate a certain degree of deviation which is produced by many thoracic and abdominal organs with breathing exercises. To develop a new breathing control system of tumor target for precision radiotherapy is the practical demand in hospital.Methods: According to the current active breathing control system, there are gasbag, control box, handle switch for the patients, computer, automatic gasbag controller, respiratory sensor and communication tools. The Pneumotach PowerCube pulmonary function respiratory sensor and C++ high level programming language were selected to program the breathing control system.Results: The system could make patients conduct respiratory control better, reduce the deviation of pulmonary tumor caused by respiratory movement and improve the accuracy of treatment.Conclusion: The system had a lot of functions, such as dispersion, oscillation, ventilation and so on. It is refitted on the current instruments and successful to clinical application.

Objective To assess the age-specific sleep time among children 2 to 12 years of age in Yuexiu district,Guangzhou,China,and to identify the related factors.Methods 1734 children,aged 2 to 12 years were randomly selected from two elemental schools and two kindergartens in Yuexiu district of Guangzhou under strict quality control system,their parents were interviewed with questionnaire to look into their familial and social environment,as well as sleep related factors.Results The total sleep time among children less than 6 years of age in Yuexiu district,Guangzhou was less than that among children the same age in other provinces in China.The factors were related to children's inadequacy of total time included age,sleep problems,the history of sleep snoring in father and mother,feeding manners,difficulty at sleep onset.Conclusion The total sleep time among children at lower age in Yuexiu district,Guangzhou is on the low side.The main influencing factor of insufficiency of sleep time among children is the family environmental factors,the sleep time should be recognized by family and society.

Objective To investigate the correlation between hope and medical coping styles among patients with diabetic foot ulcer.Method Fifty-four inpatients and outpatients with diabetic foot ulcer were investigated by the demographic questionnaire,the Herth hope index(HHI)and medical coping modes questionnaire(MCMQ)to investigate the status of their hope and coping styles and the correlation between them.Results The average score of hope was(36.50±5.06),which was at the high level.Confrontation was lower than the norm in coping styles(all P<0.05)and the differences between avoidance,acceptance-resignation and norm were not statistically significant(P>0.05).The average score on hope was positively correlated with confrontation but negatively correlated with avoidance(all P<0.05),and there was no significant correlation with acceptance-resignation(all P>0.05).Conclusions The hope of patients with diabetic foot is high.It is positively correlated with confrontation and negatively correlated with acceptance-resignation in coping styles.Nurses should instruct the patients to adopt positive coping styles,avoid negative coping styles and keep them at a higher level of hope.

T was genotyped by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)in all the patients.Results The occurrence of CR in this population was 23.3%(70/300).There was CYP3A4 894C/T polymorphism in the study population.The frequencies of the three kinds of genotypes(CC,CT,TT)in CR group and non-CR(NCR)group were 45.7%,50.0%,4.3% and 63.5%,31.7%,4.8%,respectively.The frequency of TT genotype was significantly higher in NCR group than that in CR group(OR=2.06,95% CI:1.201-3.547,P=0.020).C allele carriers were more likely to develop clopidogrel resistance compared with that of T allele carriers(OR=1.59,95% CI:1.037-2.442,P=0.023).Conclusion CYP3A4 gene 894C/T polymorphism is associated with the risk of CR,and C allele carriers may be a possible genetic susceptibility factor for patients with CR.

Objective To investigate the levels of aluminum in serum of people who long-term consumed the foods contained aluminum. Methods 1 500 people who like to enjoy the Chinese traditional foods in which aluminum often contained were investigated and the serum were collected for determination of aluminum, the other 1 500 people whose dietary habits were not the same as that of the former were chosen as the control. Results In the people who like to enjoy the Chinese traditional foods, the number of people who burdened a high level of aluminum in serum(572) was much larger than that of the control(40), and the time-effect relationship was found. Conclusion The aluminum contained foods should be controlled and restricted in China to prevent and reduce aluminum intake.

Objective To explore the relationship between the fundus vascular changes with the stage and risk stratification of essential hypertension(EH) and the cardiac function.Methods One hundred patients with EH in our hospital from April 2011 to March 2016 were selected and divided into the control group(n=29),Ⅰ-Ⅱ group(n=56) and Ⅲ-Ⅳ group(n=15) according to the Keith-Wagener fundus grading.The stage and risk stratification of EH (mild,moderate,severe),cardiac function indexes[left ventricular end-diastolic inner diameter (LVEDD),left ventricular wall thickness (LVPWT),interventricular septum thickness (LVST),left ventricular mass index (LVMI),carotid intima-media thickness (IMT),left ventricular ejection fraction (LVEF)] were compared among 3 groups.Results The proportions of mild hypertension in the control group,Ⅰ-Ⅱ group and Ⅲ-Ⅳ group were 55.17％,21.43％ and 6.67％ respectively,the proportions of moderate hypertension were 31.03％,30.36％ and 26.67 ％ respectively,which of severe hypertension were 13.79 ％,48.21 ％ and 66.67 ％ respectively,the differences were statistically significant(x2 =5.568,P=0.019).The cardiac indexes of LVEDD,LVPWT,etc.had statistical differences among the control group,Ⅰ-Ⅱ group and Ⅲ-Ⅳ group(P＜0.05).The fundus vascular changes were positively correlated with the stages and risk stratification of EH (r=0.742,P =0.002),while LVMI (r =0.674,P =0.028) and IMT (r =0.598,P =0.014) were negatively correlated with LVEF(r=-0.623,P=0.035).Conclusion The fundus vascular changes have close correlation with the stage and risk stratification of EH and cardiac function,which could be used as an important index for judging the hypertensive severity and target organ damage situation
