Objective To assess the efficacy and safety of different dosages of oxycodone plus acetaminophen for treating acute pain after oral surgery,in order to provide a reasonable dosage of combination in clinic. Methods Randomized controlled trials ( RCTs ) on effect of combination of oxycodone plus acetaminophen on pain relief after oral operation were searched from the following data-bases:PubMed,EMbase,MEDLINE ( Ovid) ,the Cochrane Library,CNKI,and WANFANG from the date of their establishment to January 2015. The data of RCTs meeting the inclusive criteria were extracted according to Cochrane methods by two reviewers independently,and after the quality was evaluated and cross-checked,meta-analyses were conducted using RevMan 5.2 software. Results A total of 11 studies in 10 literatures involving 1 028 patients were included and were designated to 3 different dosage groups (5 mg/325 mg,10 mg/650 mg,10 mg/1 000 mg,respectively). The results of Meta-analyses showed that pain remission rate was significantly higher in the 3 different dosages of oxycodone plus acetaminophen groups than in the placebo group (RR5 mg/325 mg=3.35,95%CI [1.74,6.45],I2=38%,P=0.000 3;RR10 mg/650 mg=6.88,95%CI [4.00,11.83],I2=0%,P<0.000 01;RR10 mg/1 000 mg=4.94,95%CI [3.23,7.56],I2=81%,P=0.005). In additional,the RR of oxycodone 10 mg/acetaminophen 650 mg and placebo groups for pain remission rate was higher than that of the other 2 dosages groups,moreover,more studies were enrolled and its low heterogeneity led to high reliability. Usage rate of remedial painkillers was significally lower in oxycodone plus acetaminophen groups than in the placebo group (RR5mg/325mg=0.71,95%CI [0.60, 0.85],P<0.000 01;RR10mg/650mg=0.50,95%CI [0.41,0.61],P<0.000 01;RR10mg/1000mg=0.77,95%CI [0.66,0.90],P=0.001) ,In addition, the RRs of usage rate in oxycodone 10 mg/acetaminophen 650 mg and placebo groups were significantly lower than the other 2 dosages groups. Incidence rates of adverse effects were similar in the 3 different dosages groups and higher than that of the placebo group. However,the adverse events were generally described as mild to moderate in severity and rarely led to drug withdrawal according to all reports in the studies ( only one event ) . Conclusion The present study showed that combination of oxycodone plus acetaminophen can provide better analgesia in acute pain after oral surgery with high safety. In addition,combination of oxycodone 10 mg plus paracetamol 650 mg may be better for acute pain relief after oral surgery.

Objective To investigate the resting-state functional connectivity of the two hemispheres between multiple system atrophy (Parkinsonian type,MSA-P) and Parkinson's disease (PD).Methods A total of 25 MSA-P,29 PD patients and 29 well-matched healthy controls recruited in the Nanjing Brain Hospital Affiliated to Nanjing Medical University from June 2013 to December 2015 were scanned with resting-state functional magnetic resonance imaging for voxel mirrored homotopic correlation (VMHC) analysis.The Mini Mental State Examination,Montreal Cognitive Assessment,Frontal Assessment Battery and Unified Parkinson's Disease Rating Scale-Ⅲ (UPDRS-Ⅲ) were used to assess the clinical symptom.Then the relationship between the change of VMHC values and severity of clinical symptoms was investigated.Results Compared with healthy controls,MSA-P and PD patients both showed decreased VMHC in bilateral cerebellum posterior lobe,precuneus gyrus,middle temporal gyrus,and postcentral gyrus.Compared with PD or healthy controls,MSA-P patients exhibited lower VMHC in bilateral putamen.Significant negative correlation between VMHC values of putamen and UPDRS-Ⅲ scores was found in MSAP patients (r =-0.607,P =0.001).Conclusion These functional changes suggest that the abnormal interhemispheric synchrony probably plays an important role in pathophysiology of both MSA-P and PD,and abnormal VMHC values in putamen of MSA-P may be helpful in differentiating MSA-P from PD.

Objective: To present the evolutionary path of Chinese Medical Ethics, analyze the development vein of periodical, explore the journal' s research focuses, and provide reference for related personnel to understand the development of the current research status in the field through visualization technology. Methods:Using biblio-metric method,taking "China National Knowledge Infrastructure" as source of data collection, we used the visual-ization software CiteSpace to draw scientific knowledge maps and analyzed literatures published from 1990 to 2014 in Chinese Medical Ethics. Results:The annualvolume of journal articles fluctuated upwards,with peaks in 1992, 2000 and 2009, and of which the most was in 2009, with 393 articles. "Medical Ethics" and "Doctor-patient Relationship" were hotwords in this field. The publications of domestic and foreign scholars promoted the interna-tional exchange and the development of Chinese medical ethics, and the most productive institutions were often col-leges or universities. Conclusion:Chinese Medical Ethics has effectively promoted the development of bioethics in China, more and more scholars are involved in the relative research of medical ethics, and the old, middle and young scientists and research teams inherit, cooperate and develop with each other. The cross-regional, inter-a-gency and interdisciplinary collaboration remains very limited, whichwill become the important factorinfluencingthe development of the field of Chinese medical ethics in the future.

Intracranial Rosai-Dorfman disease (RDD) is a rare clinical histiocytosis proliferative disease. A 12-year-old boy with dizziness and headache for 1 month was admitted into Pediatric Neurosurgery of Xiangya Hospital, Central South University. The patient underwent total tumor resection and postoperative application of hormones and chemotherapy. During follow-up of 8 months, patient's condition was stable and no tumor recurrence was observed. For patient with a trend of tumor progression, stereotactic biopsy can help to confirm the diagnosis and determine the surgical strategy such as disposal of bone flaps. The treatment is mainly based on surgical intervention, supplemented by radiotherapy, chemotherapy and hormone therapy. Without affecting the nerve function, the surgeon should try to completely resect the tumor.
