Objective To evaluate the efficacy and safety of the treatment with Octreotide combined with rhubarb for acute severe pancreatitis(ASP).Methods Randomized controlled trials(RCTs)were searched from the following data-bases as CBM、VIP、CNKI、PubMed and WanFang ,all RCTs searched from January 2008 to December 2014.Search terms were Octreotide,rhubarb,ASP.Two reviewers according to the Cochrane systematic review,pre-defined inclusion and exclusion criteria,then screening literatures,extraction data and assessing literature′quality independently,finally unifided datas by cross-checked,Meta-a-nalysis was performed by RevMan5.2 software.Results Ten RCTs involving 655 patients (treatment group:336 cases,control group:31 9 cases)were included.Meta-analysis results showed that compared with the use of Octreotide,Octreotide combined rhu-barb advanced the clinical cure rates[RR=1.47,95%CI (1.21,1.78),P <0.01 ]and the total clinical effective rates [RR = 1.1 9, 95%CI (1.09,1.29),P <0.01];Octreotide combined rhubarb shorted the remission time of abdominal pain,the remission time of vomit,the recovery time of serum amylase,the recovery time of urine amylase,hospitalization days,the first defecation time,the ab-dominal distension disappear time and the remission time of signs of abdominal tenderness,the differences all above showed statisti-cal significance(P <0.01).But reducing the proportion of surgery didn′t have statistic difference(P >0.05).No severe adverse e-vents or allergic reactions were reported.Conclusion Compared with the traditional Octreotide therapy alone,rhubarb combined with Octreotide therapy for ASP have a better curative effect.

Objective To assess the effectivity and safety of oxycodone plus acetaminophen for postoperative acute pain re‐lief .Methods Randomized controlled trials (RCT ) on combination of oxycodone plus acetaminophen treating postoperative pain re‐lief were searched from the following data‐bases as PubMed ,EMbase ,MEDLINE(Ovid) ,the Cochrane Library ,CNKI and WAN‐FANG from the date of their establishment to September 2014 .The data of RCT meeting the inclusive criteria were extracted ac‐cording to Cochrane methods by two reviewers independently ,and after the quality was evaluated and cross checked ,meta analyses were conducted using RevMan 5 .2 sotware .Results A total of 18 studies involving 2 213 patients were included .The results of Meta‐analyses showed that compared with placebo group or the equal dosage oxycodone alone group ,the combinations of oxycodone plus acetaminophen were more effective in postoperative pain relief (P<0 .01) .However ,there are no significant difference in the effective between the combinations of oxycodone plus acetaminophen and the higher dosage oxycodone alone group or the acetamin‐ophen alone group for postoperative pain relief (P>0 .05) .Adverse events occurred more frequently with combination therapy than placebo or acetaminophen alone group ,but were generally described as mild to moderate in severity and rarely led to withdrawal . There are no significant difference in the adverse events between the combination of oxycodone plus acetaminophen and the oxyc‐odone alone group .Conclusion The present study showed that combination of oxycodone plus acetaminophen is effective and high safe in postoperative acute pain relief .

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.

Cardiovascular diseases have become the most common and most prevalent chronic diseases in the elderly.Smoking, hyperlipidemia, diabetes and other high-risk factors participate in the occurrence and development of atherosclerosis by impairing the structure and function of the vascular wall, resulting in the occurrence of arterial stiffness.Pulse wave conduction velocity(PWV) is the rate at which a pulse wave travels from one specific location of the artery to another specific location along the wall of the artery.It is a simple, effective and repeatable noninvasive index for evaluating arterial elasticity and vascular function.PWV is closely related to cardiovascular disease.In recent years, the relationship between PWV and cardiovascular disease has been deeply studied.The relationship between PWV and coronary heart disease, hypertension, cardiac function, atrial fibrillation and pulmonary hypertension is described in this paper.
