Sleep disorders are commonly occurred among patients with Parkinson's disease,such as difficulties in the initiation of sleep,fragmented sleep,sleep behavior disorder and excessive daytime sleepiness.The mechanism of sleep disorders associated with Parkinson's disease is not clear,which may be associated with the injury of brain stem,nuclei of median raphe,nuclei fasciculi solitarii,thalamencephalon and the changes of neurotransmitters as dopamine,hypocretin(orexin) and melatonin.This article gives an overview of the mechanism of sleep disorders associated with Parkinson's disease.

Prolyl-4-hydroxylase domain (PHDs) family is one of the most important regulatory factors in hypoxic stress. PHD2 plays a critical role in cells and tissues adaptation to the low oxygen environment. Its hydroxylation activity regulates the stability and transcriptional activity of the hypoxia-inducible factor 1 (HIF-1), which is the key factor in response to hypoxic stress. Subsequently, PHD2 acts as an important factor in oxygen homeostasis. Studies have shown that PHD2, through its regulation on HIF-1, plays an important role in the post-ischemic neovascularization. Furthermore, under hypoxic condition, PHD2 also regulates other pathways that positively regulate angiogenesis factors HIF-1 independently. Moreover, recently, several evidences have also shown that PHD2 also affects tumor growth and metastasis in a tumor microenvironment. Based on these facts, PHD2 have been considered as a potential therapeutic target both in treating ischemic diseases and tumors. Here, we review the molecular regulation mechanism of PHD2 and its physiological and pathological functions. We focus on the role of PHD2 in both therapeutic angiogenesis for ischemic disease and tumor angiogenesis, and the current progress in utilizing PHD2 as a therapeutic target.

OBJECTIVEDiscuss the surgical treatment of jugular foramen and hypoglossal canal tumor, and choice of the best surgical approach.
METHODS32 patients with jugular foramen and hypoglossal canal tumor were operated through the postauricular tran-supracondylar approach, 13 neurinoma, 7 glomus jugular tumors, 4 meningioma, 3 chordoma. 23 were total removed, with a subtotal of 9.
RESULTS21 patients were followed up, mean 2.5 years. 18 patients work normally, 7 of them were hoarseness, 2 of other 3 patients lived by themselves, 1 of existed obstruct of limbs.
CONCLUSIONSPostauricular tran-supracondylar approach exposes satisfactory for the dumbbell-shape tumors of intra-or extra cranial. It has high rate of total removal and low rate of complications. It is the best approach of treatment in jugular foramen and hypoglossal canal tumors. The outcome is good.

OBJECTIVETo study the clinical characteristics, diagnosis and surgical treatment of malignant intracranial teratomas.
METHODSThirty-four patients with intracranial teratoma proved by histopathology were treated by operation. The growth pattern of this tumor, assessed by its clinical manifestations and neuroimaging together with surgical treatment and results were analyzed retrospectively.
RESULTSOnly 6 lesions had been correctly suspected as teratoma before surgery. Total removal was achieved in 14 patients with a operative mortality of 32.4%. The survival of 23 patients with lesions showing aggressive growth was significantly different from those without (P < 0.05). Nineteen of these patients did not survive beyond the sixth month after surgery.
CONCLUSIONAccurate preoperative diagnosis is difficult in malignant intracranial teratoma, especially for patients with the tumor in the sella region. The invasive biological behavior of the tumor is proved to be the main cause of surgery being dwarfed. Protection of the hypothalamus and brainstem, relief of hydrocephalus are the crucial points in surgical treatment. Comprehensive histopathologic examination combined with serum and CSF tumor marker detection is necessary for correct diagnosis and treatment.

OBJECTIVETo study the diagnosis and microneurosurgical treatment of cavernous sinus neurinoma.
METHODSTwenty-two patients with cavernous sinus neurinoma which had been diagnosed by MRI were operated on by microsurgery. Fourteen patients received excision of tumor through frontotemporal approach with zygomatic osteotomy and, 8 patients via subtemporal and suboccipital transtentorial approaches.
RESULTSTotal resection was achieved in 21 patients (95.5%), and subtotal resection in 1. There was no operative death. The all operative samples were confirmed neurinoma pathologically. The symptoms postoperation such as headache and exophthalmos were reduced. Three months after operation, the function of the 6th nerve was improved in 12 of 19 patients with paresis of the 6th nerve. One patient with hemiplegia recovered well. The function of the 3th nerve recovered in 4 of 6 patients with recurrent paresis of the 3th nerve. Those patients with hydrocephalus were improved after operation. The patients were follow up 8 - 60 months (mean 20 months). No tumor recurrence was observed.
CONCLUSIONCavernous sinus neurinoma can be removed successfully via subtemporal and suboccipital transtentorial approaches.

The volatile components of roots and stems of Zanthoxylum nitidum were investigated by supercritical fluid carbon dioxide extraction (SFE-CO2) and gas chromatography-mass spectrometry(GC-MS). Thirty-one and fifty-one compounds were identified in the supercritical extracts from roots and stems of Z. nitidum, respectively, and total twenty-seven compounds were the common constituents. Among them, the major constituents in root and stem supercritical extracts were spathulenol (18.49 and 26.18%), n-hexadecanoic acid (14.24% and 12.79%), ar-tumerone (6.95% and 8.88%), oleic acid (8.39% and 5.71%) and hexanoic acid (4.39% and 7.78%). The in-vitro MTT assay showed that the volatile components of roots and stems of Z. nitidum did not exhibited any cytotoxic activity against human cancer Huh-7 and normal IEC-6 cells. These results indicated the same nature of the volatile constituents in the root and stem of Z. nitidum. This investigation may provide further evidence for expansion of medicinal parts of Z. nitidum.
