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.

Chinese Pharmacological Bulletin 2014;(7):889-892,893
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 explore the effect of multi-disciplinary management for aneurysmal subarachnoid hemorrhage treated with clipping surgery. Methods 123 subjects admitted to hospital in April 2005 to March 2007 and received traditional management were named as the control group.62 subjects in the control group who admitted to neurology department first and then transferred to neurosurgery when diagnosed as aSAH by DSA were named as the transfer group. 61 subjects who admitted to neurosurgery directly and diagnosed as aSAH by DSA were named as the surgery group. 101 subjects who received multidisciplinary management from April 2007 to March 2009 were named as the experimental group. The waiting time before DSA, waiting time before surgery, hospital stay and hospitalization costs were compared between the three groups. Results Compared with the transfer group and the surgery group, the experimental group was lower in waiting time before DSA, waiting time before surgery, hospital stay and hospitalization costs, but there is no significant difference between the three groups in postoperative neurological function score and incidence rate of complications. The mortality rate was not significantly higher in the experimental group than the transfer group, but was significantly lower than the surgery group. Conclusions Multi-disciplinary management can reduce the "inappropriate hospital stay" of aSAH patients for early surgery. It can reduce the average hospital stay, hospital cost, in order to reduce the burden on families and society.

A poly( GMA-EGDMA) coated SPME fiber was prepared using an in-situ polymerization by direct bonding to the surface of a polydopamine-modified stainless steel wire. Then the fiber was modified by sulfuric acid. A novel solid phase microextraction coating coupled to high performance liquid chromatography ( HPLC) method based on the as-prepared fiber was developed for the determination of four pharmaceuticals and personal care products ( PPCPs) in water samples. The influences of extraction parameters, including pH, extraction time, extraction temperature and salt addition were investigated. 3 mL water sample was extracted by the as-prepared fiber for 60 min at 30 ℃, and then desorbed with mobile phase for 30 min, respectively. Desorption solution was analyzed by HPLC-DAD ( diode array detection ) . The results indicated that the extraction yield of the fiber was good for four PPCPs. The linear correlation coefficients were>0. 997 with the linear range of 2-200 μg/L. The limits of detection (S/N=3) were 0. 5-5 μg/L with RSD (n=5) of 4. 1%-11. 9%. The recoveries of four PPCPs at spiked level of 20, 50, 100 μg/L were within the range of 70. 6%-105. 5%. The results showed that this method was easy, green, accurate and precise, and could be used to assay the four PPCPs in real water samples.

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.
