Objective To investigate the value of CT and MRI in diagnosing facial nerve neuroma. Methods The CT and MRI findings of facial nerve neuroma proved by surgery and pathology in 6 cases were retrospectively analysed. Results Four of the six facial nerve neuroma only affected intratemporal segment of facial nerve (labyrinthine segment 1, tympanic segment 2, mastoid and tympanic segment 1), one involved the cerebellopontine angle(CPA) cistern, internal anditory canal(IAC) and intratemporal segment and last one involved both the intratemporal segment and the intraparotid gland segment. The imaging manifestations of the tumor depended on its location and extension. On CT, the tumors of intratemporal segment showed enlargement and destruction of facial nerve canal, soft tissue mass in the middle ear and /or in the mastoid, erosion of the aterior surface of the petrous bone at the level of the geniculate ganglion fossa, and extension to the middle cranial fossas and intraparotid gland. One neuroma arising from IAC and cisternal segments demonstrated a mass in the CPA, widening of the IAC, enlargement of the labyrinthine segment of the facial nerve canal, and extension to geniculate ganglion fossa by CT and MRI. Conclusion CT and MRI are accurate to describe the extent and location of facial nerve neuroma. CT is better to demonstrate the osseous destruction in detail, whereas enhanced MRI evaluates the tumor itself more accurately.

Objective to investigate the characteristics of externalizing problems behavior and related factors in new generation migrant workers so as to provide a decision making basis for consensus propaganda,psychological assistance and intervention.Methods A total of 1 340 new generation migrant workers(male 862,femal 478) were extracted from the gathering areas of mi grant workers in the three cities of Chongqing,Shenzhen and Hangzhou,the questionnaire survey and evaluation were performed by adopting the Youth Self-Report (YSR),Harter Self-Perception Profile(HSPP),Lum Emotional Availability of Parents (LEAP),Perceived Availability of Social Support Questionnaire(PASSQ) and Psychological Acculturation Scale(PAS).Results The tested externalizing problems were slightly higher than the non-clinical tested reasonable scoring range,the peer support had statistical difference between sexes(P＜ 0.01),the personal ability and comprehensive self value had significantly positive correlation (P ＜ 0.01),and both were negatively correlated to the externalizing behavior problems(P＜0.01),parents' emotional availability and support showed significantly negative correlation to externalizing behavior problems(P＜0.01),the working environment support was negatively related to externalizing behavior problems(P＜0.05).The prediction of personal effectiveness to externalizing prob lems behavior was obvious(P＜0.01),the social acceptance(P＜0.01) and overall self value(P＜0.01)were the predictive factors of externalizing problems behavior,and the work environmental support had the predictive effect on externalizing problems behavior (P＜0.05).Conclusion Personal ability,parents' emotional availability and support,work environmental support and social acceptance are correlated with externalizing behavior problems in new generation migrant workers.The overall self value,social accept ance,mother's emotional availability and parents' emotional support have significant prediction,while the work environmental support has a predictive effect on externalizing behavior problems.

AIDS has become a global disease,and a variety of drugs are used in the treatment of AIDS ,but the interindividual variabilities in efficacy and toxicity remain important limitations for the use of these drugs.Studies have shown genetic polymor-phism is the main reason for interindividual variabilities of drug reaction.In recent years,scholars focused on the pharmacog-enomics of anti-AIDS drugs and found that genetic polymor-phisms,in large part,determine the interindividual variabilities of the responese of these drugs.This paper reviews the research progress on pharmacogenomics of the four types of anti-AIDS drugs commonly used in China,including nucleoside reverse transcriptase inhibitors (NRTIs),non-nucleoside reverse tran-scriptase inhibitors (NNRTIs),protease inhibitors (PIs)and integrase inhibitors (raltegravir).

Objective To discuss Extracorporeal Membrane Oxygenation(ECMO) management method and effect during inter-hospital transport of potential cardiac death donors after cardiac death (DCD).Methods 8 potential donors after cardiac death with brain injury were supported by ECMO for inter-hospital transport.All donors were inserted Medtronic overall cannula into one side femoral artery and venous.The position of catheters were guided by ultrasound.The front-end of venous catheter located in the junction of atrium and inferior vena cava,meanwhile the front-end of artery catheter was below renal artery.100 IU/kg heparin was injected before inserting cannulas.Flow of ECMO maintained at 2.0～3.0 L/min,and oxygen flow was 2～3 L/min during ECMO supporting.When hemodynamics of potential donors were stable,patients were moved into ambulance with ECMO for inter-hospital transport.Results A total of 8 ECMO transports were performed for central circulatory collapse caused brain injury.Patients were previously cannulated and on ECMO prior to transport and transported a distance of more than 100 kilometer from our institution by ambulance.ECMO running times were 120 min,and operation process circulatory stable.Conclusion ECMO can ensure inter-hospital transport of potential donors after cardiac death safety.

The traditional Chinese medicine (TCM) theory of "treating heart and brain diseases with same methods (Nao Xin Tong Zhi: NXTZ)" has great significance to the treatment of cardiovascular and cerebrovascular diseases. It has been proven effective by a great deal of clinical researches. However, the underlying mechanism for this theory is still unclear. To provide insights into the potential mechanism of "NXTZ", this study attempts to deeply investigate the mechanism from two representative cardiovascular and cerebrovascular diseases, coronary heart disease (CHD) and cerebral apoplexy. First, various data resources were integrated to obtain different types of biomedical entities including drugs, targets, pathways and diseases. Then, three different approaches including text mining, biological network and enrichment analysis were utilized to recognize the potential common features between CHD and cerebral apoplexy, and the corresponding functions of drugs which could treat both diseases, thus unveiling the mechanism of NXTZ.
