Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

Objective:To access the benefits and harms of remote ischemic preconditioning(RIPC) in patients undergoing cardiac surgery with cardiopulmonary bypass.Methods:An electronic and manual search of literature published before Mar 2020 was conducted using Pubmed, EMBASE, Cochrane Library for randomized controlled trials(RCTs), CNKI, CBM, WanFang and VIP. 23 studies involving in 5 025 participants were included. Patients were randomly assigned to either remote ischemic preconditioning group(n=2 524) or control group(n=2 521). Remote ischemic preconditioning consisted of 3-4 cycles of lower limbs or upper limbs ischemia and reperfusion with an automated cuff inflator. Clinical data and the levels of injury biomarkers were collected. The main outcomes were the incidence of adverse events, mortality in the hospital, and the post-operative troponin concentration. The effective values of dichotomous variables or continuous variables were estimated by Relative risk( RR) or by mean differences( MD), standardized mean differences( SMD) with 95% confidence intervals( CI) respectively. Results:In general risk of bias varied from low to moderate risk of bias across included studies, and insufficient detail was provided to inform judgement in several cases. There were no significant differences between the two groups with regard to all-cause mortality in hospital( RR=1.27, 95% CI: 0.84-1.91, P=0.26), no-fatal myocardial infarction( RR=0.92, 95% CI: 0.79-1.07, P=0.27) , new stroke( RR=0.96, 95% CI: 0.61-1.50, P=0.84), new atrial fibrillation( RR=0.98, 95% CI: 0.83-1.15, P=0.77) and acute renal failure( RR=1.01, 95% CI: 0.90-1.14, P=0.83). Conclusion:There is no evidence that RIPC has a treatment effect on clinical outcomes(measured as all-cause mortality in hospital, no-fatal myocardial infarction, new stroke, new atrial fibrillation, and acute renal failure). More research should be designed to confirm the effect of RIPC on myocardial protection with cardiopulmonary bypass.

Objective To investigate the effects of Thomas solution in combination with nitroglycerine of different concentrations on rat cardiac preservation for 8 h. Methods Thirty Wistar rats were selected,and Langendorff heart perfusion models were established.Rats were randomly divided into Thomas solution group,Thomas solution+4?10-6 mol/L nitroglycerine group and Thomas solution+4?10-5 mol/L nitroglycerine group(n=10).After hypothermic preservation(4 ℃)for 8 h,the cardiac function of each group was determined.Tissues of left ventricular wall were obtained,and changes of myocardial ultrastructure were observed by electron microscopy. Results Compared with Thomas solution group,the cardiac function was significantly improved and the myocardial ultrastructure injury was less severe in Thomas solution+4?10-5 mol/L nitroglycerine group after hypothermic preservation(4 ℃)for 8 h,while there was no significant difference in myocardial ultrastructure injury and cardiac function between Thomas solution group and Thomas solution+4?10-6 mol/L nitroglycerine group. Conclusion Thomas solution in combination with 4?10-5 mol/L nitroglycerine can significantly improve the preservation effects for isolated hearts in rats.
