Objective To develop a new technique of air purification by plasma combined with photocatalysis. Methods Taken trichloroethylene as the air pollutant, the combined tests of the plasma unit and photocatalysis unit were conducted in different ways of combination (plasma and photocatalysis, photocatalysis and plasma) by adjusting the distance and setting some nets between them, then the purify efficiency was evaluated. Results The way of combination (plasma and photocatalysis) showed the best purify efficiency, when the distance was 32.5 cm, purify efficiency was more than 90%, steel net could increase purify efficiency by 6%, non-woven fabric by 9%. Conclusion The combined usage of plasma and photocatalysis, keeping a fit distance and setting a net of special material, may produce a considerable synergistic effect in air purification.

Objective:To clarify the essence of hospital equipment management and propose the task and development trend of information management need to be accomplished, and solve the bottleneck problem of system design, which is always focused on the process of hospital equipment information management promotion in our country.Methods: Comprehensively analyzed daily work of hospital equipment management, and designed a new dual core equipment information system architecture, which was ex purchasing + post purchasing dual core architecture.Results: Based on the new architecture, the hospital equipment information system can cover the entire equipment management workflow, and it made information transmission between jobs more efficiently, cooperation more closely, responsibilities more clearly, constraint more effectively.Conclusion:The new system architecture emphasizes the role of collective labor. It depends on all the members of the equipment department to work together for the goal of achieving dynamic and full life-cycle equipment management.

Objective To observe the therapeutic effects of curcumin on pulmonar y fibrosis rats induced by bleomycin. Method One hundred and forty-four male Sp rague-Dawley rats were randomly divided into 6 groups (24 rats in each group). Rats in the model control group,positive medicine group,and high-,moderate-and low-dosage curcumin groups were injected with a single dose of bleomycin th rough trachea,and rats in sham-model control group with the same volume of nor mal saline. One day after the injection,curcumin solution of different dosages (200,100,50 mg?kg-1?d-1) was respectively given to rats in the high-,mod erate-and low-dosage curcumin groups daily by gastric gavage,while the same v olume of normal saline was given to those in the sham-model control group and m odel control group,and the same volume of prednisone(0.56 mg?kg-1?d-1) was given to those in the positive medicine control group. On the 7th,14th,and 28t h day after medication,8 rats in per treatment group were randomly killed,the changes of lung function were observed,and the lung was incised to make patholo gical sections which were stained with HE and Mallory. Results Curcumin improved lung function. The results of pathological examination showed that curcumin rel ieved the pathogenic changes of the lungs of pulmonary fibrosis rats induced by bleomycin. Conclusion Curcumin exerts a certain curative effect on pulmonary fib rosis rats induced by bleomycin.

Objective To investigate the imaging appearances of esophageal tuberculosis.Methods 5 cases of esophageal tuberculosis proved by pathology were retrospectively analyzed.There were 2 male and 3 female patients aged between 24 and 36 years median age 29 years. All cases were undergone esophageal barium examination, CT scan and gastroscopy. The surgical resection of the tumor was complemented in one case.Results Esophageal barium contrast study showed: the location of lesions at upper, middle and low esophagus in 1,3 and 1 cases respectively. The X-ray features included filling defect in 2 cases, centripetal strictures in 2 cases, intraluminal barium patch in 1 case, extramural irregular fistulous formation in 1 case, mucosa destruction in 2 cases and mucosa flattened or disappeared in 3 cases. On chest CT, bronchiectasis in the posterior basal segment of left inferior lung in 1 case, enlargement of right hilum of lung and small nodule in the right chest wall in 1 case, irregular thickening in the wall of inferior oesophagus in 1 case, pleural adhesion in 1 case were showed, and the other two were normal. The accurate diagnosis was confirmed only in 2 patients preoperation.Conclusion Esophageal tuberculosis extent is not of imaging characteristics, its diagnosis should be in combination with clinical data.

[Objective]To investigate the inhibitory effect and mechanism of the microRNA-320d(miR-320d)on epithelial mesenchymal transition in endometrial carcinoma JEC cells.[Methods]JEC endometrial carcinoma cell lines were transfected with miR-320d mimics or negative control mimic,respectively,as M320d or NCM group. Control group was established with untreated JEC endometrial carcinoma cells. miR-320d content in each group was detected by RT-PCR method. Transwell assay was used to detect the migration and invasion ability of the 3 groups. Western-blot assay was used to detect the expressions ofα-Catenin,E-cad-herin,Vimentin and PBX3 protein in 3 groups. Antagonistic effect of PBX3 overexpression on miR-320d inhibition of EMT was detect-ed by western blot assay. The relationship between miR-320d and PBX3 was detected by dual luciferase assay.[Results]The expres-sion level of miR-320d in M320d group was significantly up-regulated,and the expression level of miR-320d was 808.25 ± 15.58 times higher than that of control group(P<0.05). The number of migrating cells in M320d group was 29.56 ± 0.59,which was signif-icantly lower than that of control group at 94.48 ± 1.02(P < 0.05). The number of invasive cells in M320d group was 7.33 ± 0.84, which was significantly lower than that of group control 86.28 ± 3.51(P < 0.05). Compared with control group ,the expression of α-Catenin and E-cadherin protein was significantly increased ,the expression of Vimentin protein was significantly decreased ,and the expression of PBX3 protein was significantly decreased. After PBX3 overexpression,the expression ofα-Catenin and E-cadherin protein were significantly decreased,the expression of Vimentin protein were significantly increased. Dual luciferase assay showed that PBX3 is a downstream target gene of miR-320d(P<0.05).[Conclusion]miR-320d may inhibit the expression of EMT related protein through the downstream target gene PBX3 and inhibit the epithelial mesenchymal transition function of endometrial carcinoma JEC cells.
