ObjectiveTo discuss neonatal hypoxic-ischemie eneephalopathy points,and the vesting of the re- lationship between the prognosis and current treatment methods. MethodsFrom January 2004 to April 2008, pedi-atric hospital treated 88 cases of HIE were assessed, inspected, grading and treated. Results8 cases in the 88 easesantomatically discharged, 51 patients (63.8 %) were recovered and 28 patients (35.0 %) improved, and 1 patient(1.3 %) died. HIE clinical severity has close relationship with prognosis. Mild and moderate cases were 78.4 % (29/37) ,53.7% (22/41) were recovered and no deaths, and severe 1 case, 1 death. ConchtsionHIE clinical severityand prognosis have close relationship, the time of birth asphyxia situation on the vesting of infants discharged andwas no significant impact.

Laser has been used in the treatment of glaucoma for more than twenty years.Its main applications include laser peripheral iridoplasty,laser trabeculoplasty,laser sclerostomy,and laser cyclophotocoagulation. Other applications such as C02 laser filtering surgery and photodynamic therapy(PDT)have just started.In this paper,a review is provided on the present applications of lasers in the treatment of glaucoma including choice of laser,indications,surgery approach and efficacy.The prospect of the future application is also discussed.

Objective To discuss the clinical manifestations and the morphological features of intracranial arteriovenous malformation (AVM) in childhood. Methods During the period from Jan. 2012 to June 2013, a total of 14 AVM patients under the age of 14 years were admitted to authors’ hospital. Of the 14 patients, 11 had a history of spontaneous intracerebral hemorrhage (78.6%), 7 complained of headache (50.5% ), 5 showed signs of unilateral limb weakness (35.7% ), and 2 was accompanied with epileptic attacks (14.3% ). The clinical characteristics, the preoperative imaging features and DSA findings were retrospectively analyzed. Results DSA showed that terminal feeding branches were visualized in 9 cases and blood supply from perforating branches was seen in the remaining 5 cases. In seven cases the feeding artery was single, while in the remaining 7 cases the feeding artery was multiple, and in four of them combination blood supply from both anterior and posterior circulation was found. The lesions were situated at the lateral or convex surface of cerebral hemisphere (n = 5), lateral ventricle (n = 4), cerebral bottom (n = 3) or medial surface of cerebral hemisphere (n = 2). The lesion’s diameter was < 30 mm in 10 cases and (30 -60) mm in 4 cases. According to Spetzler- Martin grading, grade Ⅰ was seen in 4 cases, grade Ⅱ in 2 cases, grade Ⅲ in 5 cases and grade Ⅳ in 3 cases. Conclusion Although in childhood AVM lesion is small in size and lower in grading, its onset is early and the lesion is prone to bleeding. DSA findings indicate that most AVMs in childhood take the form of immature type. Nevertheless, its natural course needs to be further studied.

Objective To compare the efficiency of χ~2-Fisher's exact test which is one of the competitive null hypothesis approaches with SAM-GS which belongs toself-contained null hypothesis approaches. Methods The two methods were used to analyze a simulation experiment which contained five different scenarios. The results were compared with the simulated initialization,and assessing indexes were calculated to compare the efficiency. Results Under the same conditions,SAM-GS always have higher power than that of χ~2-fisher's exact test. However, the final inference is equivalent, namely if the difference between the two groups are smaller than 0.30,the two methods can not be better to identify differences between them. By contrary, when the differences between the two phenotypes are larger than 0.30, the two ways can both identify differences. Conclusion SAM-GS tends to have slightly higher power thanχ~2-Fisher' s exact test. The two methods can be used for screening enrichment gene sets of gene expression profile.χ~2-Fisher's exact test has the important advantage of being able to analyze multi-class phenotype.

Objective To investigate the necessity of releasing the distal holdfast fibers of the flexor retinaculum(DHFFR) during endoscopic carpal tunnel release(ECTR).Methods The Experiment Group included 16 cases.The operation was conducted under brachial plexus anesthesia without the use of tourniquet.A 1 cm skin incision was made.The USE system(Universal Subcutaneous Endoscope System) was employed.Both flexor retinaculum(FR) and distal holdfast fibers of the flexor retinaculum were cut off.Postoperative outcomes were compared with another 16 cases of flexor retinaculum release only(Control Group).Results Follow-up evaluation was carried out at 6 postoperative months.According to the Kelly's criteria,there were 13 cases of excellent results and 3 cases of good results in the Experiment Group,and 8 cases of excellent,5 cases of good,and 3 cases of fair results in the Control Group.Significant difference was obser red in flameda Ⅱ or Ⅲ grade patients between the two groups in carative effects(?~2=6.278,P=0.043).No serious complications or postoperative recurrence occurred.Conclusions Flexor retinaculum is not the only structure existing in the carpal canal to be released.More attention should be paid to complete decompression of both flexor retinaculum and distal holdfast fibers of the flexor retinaculum,especially in those who have serious symptoms.

Non-motor symptoms are an important component of the manifestations of Parkinson's disease(PD);they usually include sleep disorder,neuropsychotic symptoms,autonomic dysfunction,pain,and so on.Non-motor symptoms are multifactorial and mainly involve various non-dopaminergic neurotransmitter systems.These symptoms are not only a result of disease progression,but also can appear in the early stage of the disease,and they can have a major impact on the quality of life.The early notice of these symptoms may lead to better therapeutic strategies and subsequently to the improvement of the quality of life in PD patients.
