Objective To observe the clinical efficacy of Chuankezhi acupoint injection combined with nursing health care education for treatment of patients with chronic obstructive pulmonary disease (COPD) at stable stage complicated with spleen kidney deficiency syndrome.Methods A prospective study was conducted. 118 patients with stable COPD and spleen kidney yang deficiency syndrome admitted to Hangzhou Third People's Hospital and Zhejiang Xinhua Hospital from February to April 2014 were enrolled, and they were divided into an experimental group (60 cases) and a control group (58 cases) according to the random number table. Both groups were given conventional treatment [including oxygen therapy, bronchodilators, corticosteroids, rehabilitation therapy in accord with the Global Initiative COPD (GOLD)]. Simultaneously, in the experimental group, Chuankezhi acupoint injection was additionally given, once daily for 12 weeks, and appropriate corresponding health education was mentioned. The lung function, quality of life and prognoses of the patients were regularly followed up for 9 months and compared between the two groups.Results After 12 weeks, one second forced expiratory volume (FEV1), FEV1/forced vital capacity (FVC) and maximum voluntary ventilation (MVV) per minute in the experimental group were significantly higher than those in control group [FEV1 (L): 1.57±0.42 vs. 1.35±0.35, FEV1/FVC: (58.62±4.56)% vs. (50.36±4.35)%, MVV (L/min): 60.62±7.56 vs. 56.95±6.33, allP < 0.05]. The quality of life evaluation form for COPD (QLICD-COPD) was used to evaluate the physical function, psychological function, social function and specific modules scores, showing that the above items in the experimental group were significantly higher than those in control group (total score: 74.69±8.92 vs. 68.62±8.95, physical function score: 74.16±8.55 vs. 66.31±7.15, mental function score: 78.69±9.79 vs. 72.64±8.45, social function score: 75.45±6.75 vs. 70.36±6.12, specific modules score: 67.52±6.33 vs. 61.36±6.17, allP < 0.05); Barthel index score was also significantly higher than that in the control group (75.41±9.24 vs. 68.43±7.95,P < 0.05). Within 9 months of follow-up, the incidence of acute exacerbation of COPD in the experimental group was significantly lower than that in the control group [5.00% (3/60) vs. 17.24% (10/58),P < 0.05]. The re-admission rate was also significantly less in patients in experimental group compared with that of control group [1.67% (1/60) vs. 12.07% (7/58),P < 0.05]. Conclusion Chuankezhi acupoint injection with health education for treatment of patients with COPD at stable stage and spleen kidney yang deficiency syndrome has good clinical efficacy, worthy to be applied more widely.

OBJECTIVETo compare the DNA methylation-related alteration induced by trichloroethylene (TCE) in human hepatic L-02 cells (L-02 cells) and SET deficient cells, and reveal the role of SET on the mechanisms in TCE-induced epigenetic pathway.
METHODSThe L-02 cells and pre-established SET deficient cells were treated with different TCE concentrations, and the changes of total cell viability, DNA methylation level and DNA methyltransferases (DNMTs) activity were measured, respectively. In addition, the TCE-induced alteration in the protein expression of DNMT1, DNMT3a and DNMT3b were analyzed by Western blotting.
RESULTSAfter treatment with TCE for 24 h, the cell proliferation level was significantly decreased in both cell lines. When concentrations of TCE were 0, 1.0, 2.0, 4.0 and 8.0 mmol/L, the proliferation levels of L-02 cells were 100.00±2.70, 83.34±2.38, 75.56±4.51, 71.67±2.77 and 66.67±1.63, respectively (F = 58.29, P < 0.001); the cell proliferation levels of SET deficient cells were 101.12±1.67, 85.01±2.33, 79.44±1.67, 78.337±3.89 and 76.11±3.33, respectively (F = 42.41, P < 0.001). When concentration of TCE reached 4.0 mmol/L, the difference of cell proliferation level between two groups was statistically significant (t = -3.51; P = 0.013). After treated by TCE for 24 h, the global DNA methylation significantly decreased in both cell lines (F value was 212.87 and 79.32, respectively, P < 0.001). The difference between two groups was not statistically significant. After treated by TCE for 24 h, the methyltransferases activities were significantly decreased in both cell cells (F values were 77.92 and 113.80, respectively, P-0.001). The SET deficiency could inhibit the decrease of methyltransferases activity under TCE treatment. When the concentration of TCE reached 8.0 mmol/L, the enzymatic activity of L-02 cells and SET deficient cells decreased to 67.61%±2.85% and 72.97%± 1.94%, respectively. The difference between two groups was statistically significant (t = -3.94, P = 0.008). After treated with TCE for 24 h, concentrations of TCE were 0, 1.0, 2.0, 4.0 and 8.0 mmol/L, and the relative protein levels of DNMT1 in normal L-02 cells increased significantly to 1.00±0.03, 1.28±0.04, 1.20±0.04, 1.62±0.05, 1.43±0.04 (F = 103.00, P < 0.001); In SET deficient cells, the expressions of DNMT1 were 1.00±0.04, 0.96±0.02, 1.19±0.05, 0.85±0.03, 0.83±0.03, which was significantly down-regulated under TCE treatment (F = 44.18, P < 0.001).
CONCLUSIONSET deficiency can significantly attenuate the TCE-induced decreases of cell viability and DNMTs activity, as well as alteration of protein expression of DNMT1 in L-02 cells, which indicated that SET was involved in the mechanism of TCE-induced cytotoxicity and epigenetic pathway in L-02 cells.
