OBJECTIVE: To observe the clinical effect of multistep breathing training combined with acupoint plastering on the treatment of patients with occupational coal worker's pneumoconiosis(CWP). METHODS: Eighty cases of male occupational CWP patients were selected as the research subject using convenient sampling method. They were divided into control group(40 cases) and treatment group(40 cases) according to random number table method. The control group was given conventional treatment, while the treatment group received multistep respiratory training combined with acupoint plastering for 12 weeks based on conventional symptomatic treatment. Before and after treatment, clinical curative effect, pulmonary function, immune function, the total score of Chronic Obstructive Pulmonary Disease Assessment Test(CAT) Questionnaire and 6 minutes walk distance(6 MWDS) in two groups were observed. RESULTS: Before treatment, there was no statistical difference on forced vital capacity(FVC), ratio of forced expiratory volume in one second(FEV_1)/FVC, lymphocyte cluster of differentiation(CD) 4~+/CD8~+ ratio, percentage of natural killer cells(NK), total CAT scores and 6 MWD(P>0.05). After treatment, the FVC, FEV_1/FVC ratio and lymphocyte CD4~+/CD8~+ ratio increased [median: 78.3% vs 80.7%, 68.7% vs 72.5%, 1.16 vs 2.00, P<0.01], 6 MWD was increased [(430.6±45.9) vs(494.8±58.7) m, P<0.01], and CAT total score was decreased [(18.1±5.6) vs(15.5±5.3) points, P<0.01] in the treatment group compared with the control group. There was no significant difference in NK cell percentage between the two groups(P>0.05). CONCLUSION: Multistep respiratory training combined with acupoint plastering can alleviate the clinical symptoms such as cough, and shortness of breath of patients with CWP, improve their lung function, regulate the function of immunity, as well as improve sports endurance.

Objective: Comparing the differences between dispensing granule decoction (DGD), standard decoction (SD) and traditional decoction (TD) of Phellodendri Chinensis Cortex (PCC) prescription to evaluate the quality of commercially available dispensing granule (DG), and establish the relevant standards for SD, TD and evaluative methods for DG. Methods: Fingerprint was established by HPLC. A comprehensive comparative study was conducted on 35 samples of DGD (three batches from each of the five A-E manufacturers), SD (10 batches) and TD (10 batches) in seven categories from five aspects of chemical composition type, representative index component content, fingerprint similarity, total peak area sum and principal component analysis (PCA); Clinically recommended equivalent corrections were performed for DGD. Results: ① Twenty-one common peaks in SD and TD were preserved in the DGD fingerprint. ② The content of magnoflorine in manufacturer A of DGD was 34.3% lower than that of SD (P < 0.05); The content of magnoflorine in manufacturer C was 35.6% lower than SD (P < 0.01), and 37.0% lower than TD (P < 0.05); The content of phellodendrine hydrochloride in D manufacturer was 22.0% lower than SD (P < 0.05), and 27.5% lower than TD (P < 0.05), The content of berberine hydrochloride in D manufacturer was 20.8% lower than SD (P < 0.05), and 23.8% lower than TD (P < 0.05). There were no significant differences between the other manufacturers' components. ③ The average similarity of each DGD and SD was greater than 0.992 6, and the average similarity of each DGD and TD was greater than 0.991 2, with high component similarity. Using the normalization method, the total peak area of the 21 common peaks of SD was 1 unit, and the ratios of the seven types of samples were 0.90, 1.03, 0.69, 0.77, 0.73, 1.00, and 1.06. ⑤ PCA showed that the distance between the B manufacturer and SD and TD was close, and the difference was small. Using the 21 common peak information of SD as the standard, the peak area plus method was used to correct the clinical recommended equivalent of DG. It was recommended that manufacturers A, C, D, and E could be reduced from 1 g equivalent to 12 g of the original decoction pieces to 10.7, 8.3, 9.2, and 8.8 g, respectively. B manufacturer was not needed to be corrected, and still 1 g was equivalent to 10 g of the original decoction pieces. Conclusion: There are differences in the content of components between DGD, SD, and TD in the real world. There is no significant difference in the proportion of components and components. These overall basically consistent differences can be adjusted by correcting the clinical recommended equivalent, thus promoting clinical rational drug use.

Objective: To investigate the role of apoptosis-inducing factor (AIF) in TAp63γ-induced apoptosis. Methods: Plasmid pcDNA3. 1-TAp63γ was transfected into human esophageal squamous cancer EC9706 cells for 24 h. Apoptosis of EC9706 cells was detected by observing DNA fragmentation.
