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 explore the clinical manifestation, imaging examination, treatment and prognosis of Alagille syndrome in a child combined with hepatocellular carcinoma. Method The clinical manifestation, assistant examination and diagnosis of Alagille syndrome combined with hepatocellular carcinoma were analyzed in the child, and the pertinent literature were reviewed. Results The 6-year-old girl was admitted to hospital for repeated jaundice, and had a history of cardiac surgery. After admission, the patient was found to have a typical face look such as frontal bossing, sunken eyes, pointed chin and hypertrophy of nasal tip. Blood biochemistry showed intrahepatic cholestasis and increased alpha-fetoprotein. Abdominal ultrasonography revealed diffuse multiple solid lesions in the liver. And magnetic resonance imaging of the liver indicated that the liver was enlarged and multiple solid space occupying masses. Jagged 1 gene detection showed heterozygosis mutation of c.1205delC. Conclusion Alagllie syndrome complicated with hepatocellular carcinoma in childhood is extremely rare, and early diagnosis and long-term follow-up are of positive significance for its treatment and prognosis.

Background Whether ocular anterior and posterior chamber exist a blood-aqueous barrier is in controversy.Conventional method can not offer a good evidence because it is unable to detect the aqueous component in the posterior chamber.Objective This study was to investigate the distribution of Gadolinium-diethylene triamine pentaacetic acids(Gd-DTPA)after peripheral iridectomy with magnetic resonance imaging(MRI)in rabbit.Methods Monocular peripheral iridectomy was performed on the right eyes in 8 clean New Zealand white rabbits and the fellow eyes were as controls.0.2 ml/kg(0.5 mol/L)Gd-DTPA,a tracer of MRI,was injected into ear vein in vivo to scan the eyes with MRI for the observation of the permeability and distribution.The signal enhanced ratio of interest region associated with time were analyzed.Results The signal in ciliary body of both eyes showed an immediately sharp enhancement within 10 minutes following the injection of Gd-DTPA with a peak intensity at 30-40 minutes,and then the intensity was gradually weaken over time.The signal was stronger in the operative eyes than that in the fellow eyes.The signal in the posterior chamber was gradually increased after operation,however,that in posterior chamber of the control eyes was lower.The interest regions of Gd-DTPA were ciliary,anterior chamber and posterior chamber,and the enhanced signal intensities were consisted in the posterior chamber after operation.However,the increase of the signal was not seen in the posterior chamber in the control eyes.Conclusions The pathway of plasma protein entering into the anterior chamber is very different from that of aqueous secretion.There exists a barrier between the anterior and posterior chamber which might be an integral part of the blood-ocular barrier.

Objective To investigate the apoptosis inducing effects of oridonin on leukemic THP-1 cells and its mechanisms of action. Methods THP-1 cells in culture medium in vitro were given different concentrations of oridonin (16～56 μmol/L) for 24, 48 and 72 h. The inhibitory rate of the cells were measured by MTT assay, apoptotic morphology was observed by Hoechst 33258 staining, and Annexin V/PI staining was used to detect cell apoptosis by flow cytometry (FCM). Caspase-3 and poly (ADP-ribose) polymerase (PARP) expression were detected by Western blotting. Results Oridonin (over 32 μmol/L) could inhibit the growth of THP-1 cells and cause apoptosis remarkably, the suppression was both in time-and dose-dependentmanner. Marked morphological changes of cell apoptosis such as condensation of chromatin was clearly observed by Hoechst 33258 staining, and Annexin V/PI staining showed that apoptotic cells gradually increased after the cells treated with oridinon. Western blotting showed cleavage of the caspase-3 zymogen protein (32×103), with the appearance of its 20×103 subunit, and a cleaved 89×103 fragment of 116×103 PARP was also found. Conclusion Oridonin can inhibit cell growth and induce apoptosis in THP-1 cells via activation of caspase-3. The results indicated that oridonin might be an important potential anti-leukemia reagent.

Objective To summarize the experience of intraoperative care for the patients undergoing microsurgery via retrosigmoid keyhole approach, so as to improve the treatment effect and minimize complications. Method The clinical records on the intraoperative care of 100 patients undergoing microsurgery via retrosigmoid keyhole approach were retrospectively analyzed. Result Using the keyhole technique and small incision, the cerebellopontine angle lesions were exposed clearly. Moreover, the proper intraoperational cooperation shortened the duration of operation, reduced bleeding and minimized postoperative complications such as cerebrospinal fluid otorrhea, intracranial infection, intracranial hemorrhage, and subcutaneous hydrops. Conclusion Proper operational postures and intraoperative cooperation can make full use of the limited space of the microsurgery via retrosigmoid keyhole approach and ensure the success of the operation.

Objective To investigate the apoptosis inducing effect of peroxisome proliferator-activated receptor r(PPARr)agomst on leukemic K562 cells and its mechanisms of action.Methods K562 cells in culture medium in vitro were given different concentrations of PPARragonist rosiglitazone(RGZ)(20-80 umol/L)for O,24,48 and 72h The inhibitory rate of the cells were measured by MTT assay,cell apoptosis was detected by Annexin V/PI staining,and the expression of P53 protein as well as the activity of caspase-3 were also detected.Results RGZ(over 40umoL/L)could inhibit the growth of K562 cells and cause apopto-sis remarkably,the suppression Was both in time-and dose-dependent manner.The expression of P53 pmtein was upregulated and the activity of caspase-3 Was increased concomitantly after the cells werle treated by RGZ.Conclusion PPARr agonist RGZ(over 40 umol/L)can induce apoptosis on K562 cells signifieantly,upregu-lation the expression of P53 protein as well as increasing caspase-3 activity may be one of its most important mechamisms.
