Objective To investigate the effect of abdominal vibration therapy on chronic obstructive pulmonary disease (COPD) patients with constipation. Methods In the respiratory department from August 2013 to July 2014, eighty-three COPD patients with constipation were divided into the experiment group (n=35) and the control group (n=48) using random digit table. The control group were treated with conventional western medicine and the experiment group received impingement abdomen vibration therapy on the basis of western medicine treatment. The two groups were compared in terms of symptoms of constipation and curative effect. Results The curative effect of the experiment groups was significantly better than that of the control group (P<0.05). The score on constipation in the experiment group was significantly lower than that of the control group (P<0.05). Conclusion The abdominal vibration therapy is effective in the treatment of COPD patients with constipation. It can improve their quality of life and be worthy of clinical application.

Objective To investigate the therapeutic effect of Shenmai injection(SMI)on neonatal hypoxic-ischemic encephalopathy(HIE)and it's possible mechanism.Methods 45 neonates with HIE were randomly divided into the SMI treatment group and routine treatment group.At the basic of routine treatment,the SMI treatment group was treated with 10 ml SMI added into 10% GS 30~50 ml via injecting into veins once a day for 7~10 d.The levels of serum S-100?,NSE were measured at 1 d,3 d,6 d after treatment.The development quotients(DQ)was evaluated at 3-month-old infants.Results Compared with routine treatment group,symptoms of nervous system in SMI treatment group were recovered obviously faster,the hospitalization time was shorter(all P

Wild-type p53 has been shown to be involved in several aspects of cell growth control. In order to study the role of wild-type p53 in the growth of lung adenocarcinoma cell line GLC-82, recombinant p53 adenovirus vector and the control LacZ gene were constructed. Infection conditions were detected by biochemistry staining for LacZ s expression product ?-gal, immunohistochemical analysis for p53 protein expression, and PCR technique for the infected cells. The cell growth rate and cell cycle were analysed with flow cytometry. The results showed that the constructed recombinant adenovirus vector could infect cells with high level expression of (?-gal and p53 protein and p53 cDNA could be found in the infected cells. The wild-type p53 could inhibit GLC-82 cell proliferation and cause cellular death. These results indicated that wild-type p53 gene mediated by adenovirus vector might be used in the treatment of lung adenocarcinoma.

Objective In order to research the best fermentation conditions of recombinant bacteria pThioHisA-B1/DH5? which contains gene of esterase B1.Methods Recombinant bacteria pThioHisA-B1/DH5? was induced in different culture media, induction temperatures, different inductor concentrations, different induction time in order to obtain the best expression effect.The expression products of different conditions were detected by SDS-PAGE and thin-layer gel scanning analysis.Results Based on the experiments, the optimized fermentation condition were that the culture medium was TB, inducing temperature was 28 ℃ and inducing time was 6 h,the concentration of IPTG was 0.4 mmol/L.The expression quantity of target protein attained 40.3% in total bacterial protein, and the soluble fusion protein accounted for 66.2% in total target proteins at the optimum conditions.Conclusion The optimized fermentation conditions of expressing fusion protein in recombinant bacteria have been found and in the conditions, soluble esterase B1 fusion protein of high yield can be obtained.

The PCR product of PvpA gene was cloned into prokaryotic expression vector pET41a(+) and the recombinant expression vector was then transformed into E.coli DH5a after identified by restriction enzyme digestion and PCR.The positive recombinant plasmid was transformed into E.coli BL21 (D3) and induced to express PvpA protein.The obtained protein was analyzed by SDS-PAGE and Western blotting,purified by Ni-NTA affinity chromatography.The results showed that the purified PvpA fusion protein was obtained successfully.The expressed protein reacted to the high anti-PvpA immune serum from rabbit specially by western blotting.This study would be helpful to established a new diagnostic method for the detection of M.gallisepticum.

Aim To investigate whether EGCG regu-lates ABCA1 expression by influencing the expression of miR-33 a to promote cholesterol efflux from macro-phages. Methods THP-1 macrophage-derived foam cells were established by co-incubated with oxLDL, and then treated with EGCG, and miR-33a expression was detected with Real-time PCR. THP-1 macrophage-derived foam cells were randomly divided into the fol-lowing groups: control group, 50 μmol · L-1 EGCG treatment group, 50 μmol · L-1 EGCG +80 nmol · L-1 miR-33a mimic treated group. Real-time PCR and Werstern blot was used to detect ABCA1 mRNA and protein expression, Oil Red O staining and high per-formance liquid chromatography were used to detect in-tracellular lipid content, and [3H] assay was used to determine cellular cholesterol efflux. Results EGCG could downregulate miRNA33 a expression in a dose-and time-dependent fashion within safe doses. EGCG significantly upregulated ABCA1 mRNA and protein expression, which could be inhibited after miRNA33 mimic transfected into cells, however. EGCG may re-duce lipid accumulation in THP-1 macrophage-derived foam cells, and this effect could also be weakened after miRNA33 mimic transfected. EGCG could reduce the accumulation of intracellular cholesterol,which was re-lated with EGCG promoting intracellular cholesterol ef-flux , and excess miRNA33 a transfected into cells could inhibit intracellular cholesterol efflux. Conclusion EGCG may upregulate ABCA1 expression by reducing miRNA33a generation, resulting in the promotion of cholesterol efflux from macrophages, which may be one of the molecular mechanisms of EGCG anti-atheroscle-rotic effect.

Objective To investigate the values of CD21 and CD43 proteins in the differential diagnosis of mucosa-associated marginal zone B-cell lymphoma (MALToma) from benign lymphadenosis. Methods The expression of CD21 and CD43 proteins in the tissues of 25 MALToma (case group) and 25 benign lymphadenosis (control group) was detected by immunohistochemistry. Results Abnormal CD21+follicular dendritic cells (FDC) meshes were found in all patients of case group. Most of the FDC meshes were sparse and broken, and a few were enlarged or fused into pieces. Intact CD21+FDC meshes were all found, and abnormal FDC meshes were not found in control group. The positive rate of abnormal FDC meshes in case group was significantly increased compared with that in control group (χ2 = 46.080, P= 0.000). The expression rate of CD43+in CD20+cells was 24 % (6/25) in case group, but it was negative in control group (χ2=4.375, P=0.030). Conclusions Abnormal CD21+FDC meshes and CD43+expression in CD20+cells are useful in the differential diagnosis between MALToma and benign lymphadenosis. The abnormal FDC meshes of MALToma are enlarged or fused in the minority of cases.

Objective To discuss the imaging appearances and causes of hepatic pseudolesions around the falciform ligament.Methods 40 patients (23 cases of A-type,17 cases of B-type) of hepatic pseudolesion around the falciform ligament examined by CT were collected.Combined with pathology of 2 cases,follow-up of 6 cases,MRI findings in 5 cases,and with the relevant literature reviewes,the density change of CT plain and enhanced scan and the causes of hepatic pseudolesion around the falciform ligament were analyzed retrospectively.Results There were low density in 25 cases,isodensity in 13 cases,high density in 2 cases in arterial phase,density lower than that of liver in 40 cases in portal phase,low or slightly low density in 27 cases and isodensity in 13 case of A-type in delayed phase.Of 40 cases,there were isointense in 2 cases of A-type in any sequence,and no sigal changes on out-phase images;there were intensity decline on out-phase images comparing to in-phase images in 3 cases of B type.Of 6 CT follow-up cases,there were no changes in 2 cases of A-type and shrinked or disappear in 4 cases of B-type;and there were more shrinked in 1 B-type case of MRI follow-up again after one month.Conclusion Hepatic pseudolesion of A-type can be resulted from focal fatty infiltration,and that of B-type can be caused by special blood-supply.They have characteristics in locations,and characteristic imaging appearances on CT and MRI images,and they can be clearly diagnosed generally.
