Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11<0,95% confidence interval (CI)-6.01 to-2.22,P<0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42<0,95%CI-5.19 to-1.66,P<0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19<0,95%CI-8.87 to 0.50,P>0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08<0,95%CI-3.09 to-1.06,P<0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.

AIM: To investigate whether Flk1~+ CD31~- CD34~- cells isolated from human adult adipose tissue have characteristics of hemangioblasts in vivo. METHODS: After sublethally irradiated (300cGy) with a caesium source, the female non-obese diabetic/severe combined immunodeficient (NOD/SCID) mice were injected with human adipose tissue-derived Flk1~+ CD31~- CD34~- cells (10~5 cells per mouse) via tail vain with 0.4 mL Roswell Park Memorial Institute medium (RPMI-1640). The control mice received the same volume of RPMI-1640 medium. All mice were killed 2 months after transplantation for further study. The differentiation potential of Flk1~+ CD31~- CD34~- cells was assessed in bone marrow and gastrointestinal tract by the methods of flow cytometry, RT-PCR, FISH, and triple-color immunofluorescence. RESULTS: Flk1~+ CD31~- CD34~- human adipose tissue-derived adult stem cells differentiated into endothelial cells and hematopoietic cells at the single-cell level in vivo. CONCLUSION: Human adult adipose tissue-derived Flk1~+ CD31~- CD34~- cells bear characteristics of hemangioblast in vivo and may have potential application for the treatment of hematopoietic and vascular diseases.

Objective To assess the incidence of thrombocytopenia and abnormal coagulation,door to needle time (DNT),and safety in patients with ischemic stroke who receive intravenous thrombolytic treatment prior to the availability of blood platelet (PLT) and coagulation results.Methods Consecutive acute ischemic stroke (AIS) or transient ischemic attack patients within 12 hours of symptom onset who were admitted from January 2009 to March 2013 were retrospectively recruited.First laboratory reports in their medical charts were collected to assess the incidence of thrombocytopenia and abnormal coagulation.In the mean time,consecutive AIS patients who received intravenous thrombolysis at Huashan Hospital during the same period were retrospectively recruited.The thrombolytic procedures were further optimized since June 10.3760/cma.j.issn.1006-7876.2014.07.00626,2012.With informed consent,intravenous thrombolysis was initiated without PLT and coagulation results after certain previous history and medications were ruled out.Thrombolytic patients were divided into two groups based on the initiation of thrombolysis before or after PLT and coagulation results.Baseline demographic data,symptomatic intracerebral hemorrhage rates,mortality on the 7th day as well as functional outcome at 3 months were collected.DNT as well as efficacy and safety of thrombolysis therapy were compared between the two groups.Results Of 298 AIS patients within 12 hours of onset,8 had thrombocytopenia or abnormal coagulation.One hundred and twenty cases of intravenous thrombolysis patients were recruited.Waiting for PLT and coagulation results prolonged DNT than without waiting for them (90 min vs 59 min; U =870.000,P <0.01).There was no statistically significant difference in the rate of symptomatic intracerebral hemorrhage (sICH),early efficacy,7 d mortality and 3-month good outcome between two groups.Conclusions The incidence of thrombocytopenia and abnormal coagulation is low in AIS patients.Initiating intravenous thrombolysis prior to the availability of coagulation results can shorten DNT,while increased risks of sICH and 7 d mortality were not observed.

Objective To determine factors associated with favorable clinical outcome in acute ischemic stroke patients who received intravenous thrombolysis.Methods Patients treated with intravenous recombinant tissue plasminogen activator (rt-PA) between January 1,2008 and May 31,2013 were recruited.Favorable outcome was defined as modified Rankin scale (mRS) score < 2 at 3 months.The baseline characteristics were compared by univariate and multivariate analysis.Results Of all the 148 patients studied,within the 4.5-hour time window,the rate of patients with a favorable outcome was 52.4% (65/124),significantly better than those beyond the time window(20.8% (5/24),x2 =8.048,P =0.005).Univariate analysis showed that age (U =2 146.000,P =0.025),TOAST classification (x2 =11.412,P =0.010),Oxfordshire Community Stroke Project (OCSP) classification (x2 =17.409,P =0.001),baseline blood glucose (U =1 446.500,P < 0.01),baseline fibrinogen (U =1 689.000,P =0.038),admission NIHSS score (U =1 140.000,P < 0.01),24-hour NIHSS score (U =458.000,P <0.01),and early symptom improvement (24-hour NIHSS score decreased ≥ 4 points,or down to 0 point;x2 =19.576,P < 0.01) were the factors associated with clinical outcomes.Multivariate analysis revealed that age (odds ratio (OR) =0.943,95% confidence interval (CI) 0.892-0.996,P =0.024),baseline fibrinogen (OR =0.448,95% CI 0.208-0.963,P =0.040),baseline NIHSS score (OR =0.749,95% CI 0.663-0.845,P < 0.01),and early symptom improvement (OR =14.970,95% CI 4.460-50.249,P < 0.01) were independent predictors of clinical outcomes.Conclusions The effect of intravenous thrombolysis on clinical outcomes of acute ischemic stroke patients is time-dependent.Age,baseline NIHSS score,baseline fibrinogen level,and early symptom improvement are independent predictors of clinical outcomes after intravenous thrombolysis.
