Methods Multi-centered, stratified randomized and parallel controlled clinical research methods were adopted in this study. From March 2009 to August 2010, 360 subjects with sub-health status were randomly divided into traditional group, flicking and poking group, and combining group with 120 cases in each group. The changes of clinical symptoms, erythrocyte sedimentation rate, plasma lactate, and whole blood viscosity (shear rates of 1, 5, 30, 200/s) as well as the efficacy and safety were observed. Results A total of 305 patients completed the trial, including 97 in the traditional group, 102 in the flicking and poking group, and 106 in the combining group. The general efficacy for the flicking and poking group and the combining group was significantly different from that for the traditional group (Plt;0.05), while there was no significant difference between the flicking and poking group and the combining group. After the intervention, the clinical symptom score, erythrocyte sedimentation rate, plasma lactate, and whole blood viscosity of the flicking and poking group and the combining group were significantly different from those of the traditional group (Plt;0.05). The clinical symptom score, plasma lactate and whole blood viscosity (shear rates of 1, 200/s) of the flicking and poking group and the combining group were not significantly different (Pgt;0.05), while erythrocyte sedimentation rate, and whole blood viscosity (shear rates of 5, 30/s) between those two groups were significantly different (Plt;0.05). All the above mentioned indexes before and after intervention in each group were statistically different (Plt;0.05). Conclusion Massage can improve the sub-health state, and the combining method has the best efficacy followed by flicking and poking, while traditional method has a poor efficacy. Intervening sub-health state with flicking and poking along bladder channels has a better efficacy than the traditional method of massage.
【Abstract】ObjectiveTo study the effect of transfection with antisense DNMT3b gene eukaryotic expression vector on the expression of DNMT3b gene in human cholangiocarcinoma cell line QBC-939. MethodsThe constructed antisense DNMT3b gene eukaryotic expression vector was transfected into the human cholangiocarcinoma cell line QBC-939 by using lipofectamine transfection reagents, and positive cell clones were obtained by using G418 selection after transfection. Whether the constructed recombinant vector was transfected into QBC-939 cells successfully was confirmed by amplifying the exogenous neoR gene with PCR method. The expression of DNMT3b gene mRNA and protein were detected by semi-quantitative RT-PCR and FCM methods respectively. ResultsFollowing the transfection of antisense DNMT3b gene eukaryotic expression vector, the mRNA level of DNMT3b gene in QBC-939 cells of human cholangiocarcinoma decreased from 0.956±0.053 to 0.209±0.023, and the protein level of DNMT3b gene also decreased from (75.38±3.22)% to (29.87±3.46)%. There were very significant differences on the expression levels of DNMT3b gene between non-tranfections group and the antisense DNMT3b gene eukaryotic expression vector transfection group (P＜0.01). ConclusionTransfection with antisense DNMT3b gene eukaryotic expression vector significantly reduces the expression level of DNMT3b gene in human cholangiocarcinoma cell line QBC-939, and this study may provide a valid tool and method to investigate the function of DNMT3b gene and its role in cholangiocarcinoma.
Objective To investigate the clinical characteristics of allergic and non-allergic asthma in Chinese adult asthmatic patients. Methods Consecutive treatment-naive adult outpatients with asthma were retrospectively analyzed in West China Hospital, Sichuan University from October 2014 to June 2016. The patients were classified into a non-allergic asthma (NAAS) group and an allergic asthma (AAS) group by skin prick test or antigen-specific IgE test. The differences between allergic and non-allergic asthma were compared in respect of gender, age, asthma control test (ACT) score, lung function, fractional exhaled nitric oxide (FeNO) level, body mass index (BMI), disease severity,etc. Results A total of 131 patients were enrolled in which 72 cases (54.96%) were allergic asthmatics and 59 cases (45.04%) were non-allergic asthmatics. The level of FeNO was statistically different (t=–2.762,P=0.007) between the NAAS group and the AAS group [(51.1±32.6)ppbvs. (69.1±41.7)ppb]. Seventeen cases of the NAAS group and 48 cases of the AAS group were complicated with rhinitis with statistically significant difference (χ2 =19.396,P=0.000). Airway limitation reversibility test showed that there were 37 cases in AAS and 20 cases in NAAS with no airway obstruction (NAO), 26 cases in AAS and 22 cases in NAAS with reversible airflow obstruction (RAO), 9 cases in AAS and 17 cases in NAAS with irreversible airflow obstruction (IAO), respectively, with statistically significant difference between two groups (Z=–2.461,P=0.014). There were 20 cases (33.9%) in NAAS and 37 cases (51.4%) in AAS with mild intermittent or persistent asthma, 18 cases (30.5%) in NAAS and 19 cases (26.4%) in AAS with moderate persistent asthma, 21 cases (35.6%) in NAAS and 16 (22.2%) in AAS with severe persistent asthma, respectively, with statistically significant difference (Z=–2.115,P=–0.034). The age, ACT score, FEV1%pred, and BMI had no statistical difference between two groups (allP>0.05). Conclusion Compared with allergic asthma, non-allergic asthma has less rhinitis, lower FeNO levels and higher prevalence of irreversible airflow obstruction.
Objective To compare the effect of decimeter wave with sodium hyaluronate product (SHP) on preventing and treating peritendinous adhesion and promoting tendon heal ing. Methods Totally 96 healthy male white 6-month-old Leghorn chickens weighing (2.24 ± 0.07) kg were randomized into group A ( decimeter wave therapy group, n=32),in which decimeter wave therapy was appl ied 1 to 21 days after operation at a frequency of 915 MHz, a power of 8 W, radiation distance of 10 cm, for 10 minutes once per day; group B (SHP group, n=32), in which 5 mL and 1.2% SHP was appl ied; and group C (control group, n=32), in which injury received no treatment. The III and IV toes of left feet of all chickens were made into tendon injury model. The general condition of animal was observed after operation; gross and histological observations were made 7, 10, 14, 18, 21 and 28 days after operation, and the biomechanical analysis was done 14 and 28 days after operation. Results Operative incision healed well, no infection and death occurred. Peritendinous adhesions in groups A, B were looser, and tendon heal ing was better than that of group C 14 and 28 days after operation. More fibroblasts with active metabol ism and more collagen formation in groups A, B than that in group C. The Pmax of group A was better than that of group B 14 and 28 days after operation (P lt; 0.05); the δmax of group A was better than that of group B 18 and 21 days after operation (P lt; 0.05), and the W0 of group A was better than that of group B 18, 21 and 28 days after operation (P lt; 0.05). There was no significant difference between group A and group B at the other time points. Conclusion Topical decimeter wave therapy and appl ication of SHP after flexor tendon repair can promote intrinsic heal ing, meanwhile they can prevent the adhesion of tendon and reduce extrinsic heal ing. Decimeter wave therapy can improve the qual ities of tendon’s wound heal ing.
