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 podocyte number, the expression of nephrin and transforming growth factor-β1(TGF-β1) in adriamycin-induced-nephropathy rat model and its significance. Methods The rat adriamycin nephrosis model was constructed to detect blood and urine biochemical indicators and observe the pathological changes of renal tissues by light microscope and electron microscope. The expression levels of nephrin and TGF-β1 as well as the podocyte number were examined at different time points by immunohistochemistry. Results The pathological changes of the renal tissues were obvious. Nephrin presented a weak signal at the end of the first week (P<0.05). TGF-β1 started to increase (P<0.05) while the podocyte number started to decrease at the end of the eighth week (P<0.05). Expression of nephrin was negatively correlated with the P<0.05) and serum creatinine (r=-0.71, P<0.05). Expression of TGF-β1 was blood urea nitrogen (r=0.62, P<0.05) and serum creatinine (r=0.59, urinary protein (r=-0.63, P<0.05), blood urea nitrogen (r=-0.72, P<0.05) and serum creatinine (r=-0.76, P<0.05); it was positively correlated with nephrin (r=0.78, P<0.01) but negatively correlated with TGF-β1 (r=-0.64, P<0.05). Conclusion The acute and chronic adriamycin nephrosis models were twice every two weeks. The genesis and development of proteinuria are closely related to the abnormal expression of nephrin. Focal segmental glomerulosclerosis occurs when the podocyte number decreases and TGF-β1 accelerates it.

OBJECTIVETo study the correlation between brainstem auditory evoked potential (BAEP) and serum neuron-specific enolase (NSE) in neonates with asphyxia and explore the role of NSE in the evaluation of hearing impairment following asphyxia.
METHODSFifty-two term neonates with asphyxia, including 38 cases of simple asphyxia (mild: 23 cases; severe: 15 cases) and 14 cases of asphyxia complicated by hypoxic-ischemic encephalopathy (HIE), were enrolled. In the double-blind trial, BAEP and NSE were simultaneously detected 7 days after birth. The patients who did not pass BAEP test received another BAEP and NSE examinations 3 months after birth. Thirty healthy term neonates served as normal control group.
RESULTSOf the 52 neonates with asphyxia, 50.0% and 21.2% of patients failed the initial and the second BAEP tests, respectively. The detection rates of BAEP anomalies in the simple severe asphyxia group in the initial and the second tests (63.3% and 26.3%, respectively) were significantly higher than those in the simple mild asphyxia group (36.9% and 5.9%, respectively)(P<0.05). The neonates with asphyxia complicated by HIE showed a higher detection rate of BAEP anomalies in the second test compared with the asphyxiated neonates without HIE (31.3% vs 16.7%; P<0.05). Mean serum NSE levels in asphyxiated neonates were significantly higher than those in normal controls (<0.01). There were significant differences in serum NSE levels between the neonates with mild and severe asphyxia (26.70+/-2.34 microg/L vs 17.18+/-3.16 microg/L; P<0.01). The asphyxiated neonates with HIE had serum NSE levels similar to the simple severely asphyxiated neonates. Serum NSE levels in patients who failed the initial BAEP test were significantly higher than those who passed the test (25.69+/-4.12 microg/L vs 17.15+/-3.09 microg/L; <0.01). Serum NSE levels had a positive correlation with wave V reaction threshold detected in the BAFP test (<0.05).
CONCLUSIONSThe serum level of NSE is closely correlated with BAEP, and it may be useful to the evaluation of the hearing impairment and the outcome in neonates with asphyxia.

OBJECTIVEVentilator-associated pneumonia (VAP) is a common nosocomial infection and is responsible for a very high mortality in neonatal intensive care unit (NICU) patients. This study was designed to investigate the etiology and high risk factors of neonatal VAP.
METHODSThe clinical data of 106 critical neonates who were treated with mechanical ventilator between 2003 and 2005 were studied retrospectively.
RESULTSOf the 106 neonates, 84 received mechanical ventilation for > or = 48 hrs. Thirty-five (41.7%) out of the 84 patients developed VAP. Univariate analysis showed that gestational age, duration of mechanical ventilation, reintubation, birth weights, primary lung disease and gamma globulin administration were associated with the development of VAP (P < 0.05). Multivariate stepwise logistic regression analysis showed that primary lung disease (OR=3.671, 95% CI=1.0-13.45, P < 0.05), duration of mechanical ventilation (OR=4.945, CI=1.51-16.21, P < 0.01), reintubation (OR=7.721, 95% CI=2.31-25.85, P < 0.01) and high-dose gamma globulin administration (OR=5.520, 95%CI=2.08-16.26, P < 0.01) were predicted factors for the development of VAP. The detection rate of gram negative bacilli (76.9%) was the highest, followed by gram positive coccus (17.9%) in VAP patients.
CONCLUSIONSOpportunistic drug-resistant bacteria are common pathogens for neonatal VAP. The risk of VAP is multifactorial, including external medical environments and patients' internal agents.
