Therapeutic effect of fixed-dose combination therapy (Polypill) for cardiovascular disease is a hot spot in the field of cardiovascular medicine. A variety of Polypill have been developed for the prevention and treatment of cardiovascular disease, and a plenty of clinical evidence of Polypills for cardiovascular disease has been accumulated all over the world. In this paper, we raise ideas and expectation about research & development thinking of Polypill and Chinese herbal compound prescription based on a meta-analysis of efficacy and safety of Polypill in the prevention of cardiovascular disease (published in JAMA in Nov. 2014) as well as main clinical research literature in this field in recent years.
ObjectiveTo systematically review the efficacy and safety of ginseng preparations in improving insulin resistance (IR). MethodsWe electronically searched databases including PubMed, MEDLINE, EMbase, CNKI, VIP, WanFang Data, and CBM from inception to October 2015, to collect randomized controlled trials (RCT) about ginseng preparations for IR patients. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 17 RCTs involving 1169 patients were included. The results of meta-analysis showed that treatment combined with ginseng preparations group was superior to the control group in levels of HOMA-IR (MD=-0.13, 95%CI -0.24 to -0.01, P=0.03), ISI (MD=0.72, 95%CI 0.25 to 1.19, P=0.003), FPG (MD=-0.90, 95%CI -1.27 to -0.52, P<0.00001), 2hPG (MD=-1.48, 95%CI -2.03 to -0.92, P<0.00001) and HbA1c (MD=-0.73, 95%CI -1.16 to -0.31, P=0.0008). No statistically differences between two groups were found in levels of FPI and F-CP. As for the safety, a total of 9 cases in the ginseng group occurred adverse reactions. Symptoms of adverse reactions included hypoglycemia, dizziness, nausea, blurred vision. ConclusionCurrent evidence shows that, treatment combined with ginseng preparations could improve insulin sensitivity and reduce blood glucose in IR patients with type 2 diabetes and metabolic syndrome. Due to limited quality and quantity of the included studies, the above conclusion need to be verified by more high quality studies.
ObjectiveTo compare postoperative analgesic efficacy and motor function recovery between ultrasound guided adductor canal block (ACB) and Femoral nerve block (FNB) in patients after total knee arthroplasty (TKA). MethodsFrom March to April 2014, 40 patients chosen to receive TKA under general anesthesia were randomly allocated to FNB group and ACB group with 20 in each group. Opioids consumption during and after operation, pain score in rest and movement, the force of quadriceps femoris, activity of knee and complications after surgery were recorded. ResultsNo differences were found in opioids consumption during and after operation, pain score in rest and movement after operation. Patients of ACB group were superior to those of FNB group in motor function recovery. At hour 2, 4, 8, 12, 24, and 48 after operation, the force of quadriceps femoris was higher in patients of ACB group than those of FNB group (P<0.05). Activity of knee was higher in patients of ACB group than those of FNB group postoperatively. ConclusionACB and FNB have equal postoperative analgesic effect for TKA patients. But ACB has less influence on the force of quadriceps femoris than FNB. Therefore, patients of ACB group are superior to those of FNB group in motor function recovery, showing better activity of knee and early time of first straight leg raising.
