Objective To investigate the effects of vasoactive intestinal peptide on transforming growth factor-β1(TGF-β1)expression in lung tis-sue of asthmatic mice with airway remodeling. Methods A total of 30 SPF grade female Balb/c mice were randomly divided into three groups:con-trol(group A),asthmatic(group B),and vasoactive intestinal peptide treatment(group C). Aerosolized ovalbumin was used to establish the asth-matic mice model. Pathological changes of bronchial and lung tissues were observed by HE,the perimeter of basement membrane(Pbm),internal wall area(WAi)and smooth muscle area(WAm)in bronchial lung tissue were analyzed using the pathological image. The expression levels of TGF-β1 mRNA and protein in lung tissue were detected by real-time PCR and Western blot. Results Pathologic changes including collagen deposition,in-filtration of inflammatory cells and smooth muscle layer thickness were found in group B. In addition,the WAi/Pbm and WAm/Pbm were significant-ly higher in group B than those of the group A(P<0.05),and lower in group C than in group B(P<0.05). The expression levels of TGF-β1mRNA and protein in group B were higher than both group A(P<0.05)and group C(P<0.05). Conclusion Vasoactive intestinal peptide may inhibit airway remodeling,which may be associated with reduced expression of TGF-β1.

Objective To investigate the relationship between mine environment and hypertension in miners. Methods 1736 male miners who worked under the ground and 825 on the ground were recruited in this study. Prevalence of hypertension under the ground and on the ground miners was compared. Results Prevalence of hypertension of miners under the ground was 23.91% and on the ground was 15.52% (χ2 = 23.56,P <0.001 ). Compared to miners on the ground, the relative risk of hypertension under the ground workers was 1.71 (95% CI 1.38 - 2.13 ). Prevalence of hypertension was correlated to the years of ground working (χ2 = 37.00, P < 0.001 ). The binary logistic regression showed significant relationship between mine environment and hypertension under the ground miners ( OR = 1.05,95% CI 1.02 - 1.08 ).Conclusion The underground environment is an important risk factor hypertension to the miners.

Objective To analyze distribution and drug resistance of MRSA separated,to probe into a treat method for MRSA infection and offer scientific gist for reasonable use of clinical antibiotic. Methods 568 MRSA separated from clinic were measured and a drug sensitivity test was performed by means of Kirby-Bautr agar diffusion method. Results 370 individual plants were filtered, the rate of inspection was 65.1%. MRSA was 36.2 % among them,MRSCON was 77.5% ,the drug resistance of MRSA to quinolones(21% ～48% ) was below MRSCON(84 %～89 % ). The drug resistance of MRSA and MRSCON obviously excelled MSSA and MSSCON ( P＜0.05 ). VRS was undiscovered. Conclusion Severe infection caused by MRS should choose vancomycin resistant enterococci to cure at fist. Staphylococcus was one of primary pathogenic bacterium caused infection in hospital, MRS had multiple drug resistance and measure range about drug resistance should be extended, which would advance the cognition about the drug resistance of antibiotic and cut off the transmitted path, reduce the drug resistance of bacteria and the infection rate in hospital.

Objective to study the effect of curcumin on tumor necrosis factor α(tNF-α)-induced osteoblast apoptosis. Methods Primary osteo-blast cells were divided into three groups:control group(no treated),group treated with tNF-α(treated with tNF-α for 24 h),and group pretreated with curcumin(treated with curcumin for 2 h,and then treated with tNF-α for 24 h). Western blot analysis was carried out with primary antibodies against caspase-2,caspase-3,caspase-8,Bcl-2,Fas,and tRAIL. Apoptosis cells were observed by immunofluorescence microscope. Results In group treated with tNF-α,the protein levels of caspase-2,caspase-3,caspase-8,Fas,and tRAIL increased(P < 0.01),whereas the protein level of Bcl-2 remained unchanged(P > 0.05). In group pretreated with curcumin,the protein levels of caspase-2,caspase-3,caspase-8,Fas,and tRAIL were lower than those in group treated with tNF-α(P < 0.01). the number of apoptotic cells was dramatically increased after the administration of tNF-α. While the number of apoptotic cells decreased in the presence of curcumin. Conclusion the present study clearly demonstrated that cur-cumin can suppress osteoblast apoptosis induced by tNF-α.

Objective To investigate the pathology and MRI features of the degeneration of lumbar intervertebral discs (IVD). Methods Thirteen human lumbar spine segments with 31 IVDs were harvested from fresh cadavers. High quality radiographs were taken for all specimens. Five segments with 20 IVD underwent MRI. Then, the radiographic and MRI findings were correlated with corresponding 87 pathologic sections. Results Variant degeneration was observed in pathologic sections in all 31 IVDs. With MRI T 2WI images, 20 IVDs showed linear and spotty high signal in the annular fibers, or most of the IVD showed high signal. On pathologic cuts, 22 of 31 IVDs showed infolding of annular fibers, 18 of 31 showed outfolding of annular fibers. On MRI T 1WI and T 2WI images, infolding and outfinding of annular fibers were seen as low signal. 20 of 31 IVDs had necrotic debris of cells in the nucleus pulposus. 14 of 20 demonstrated spotty low signal areas on MRI T 2WI images.7 Schmorl nodules were found. On pathologic sections Schmorl nodules were seen as IVD tissue protruding into vertebral endplates, they were seen as high signal on T 2WI images. Two large fissures found on sections were seen as low signal on T 2WI. Degenerative fibrosis seen on 6 IVD, which showed intermediate signal on T 2WI images. However, radiographs only demonstrated osteophytes on 3 vertebrae, 7 Schmorl's nodules. Sclerotic, concave and irregular endplates were seen in 11 IVDs, the latter is the indication of cartilaginous endplate disruption. Conclusion MRI is very useful in demonstrating the degeneration of IVD, radiograph is able to indirectly show the disapperance of cartilaginous endplate.

Objective:To analyze the correlation between cyclosporin A blood concentration and drug-induced liver and kidney in-jury in the patients with aplastic anemia, investigate the significance of cyclosporin A concentration in the monitoring of liver and kidney toxicity, and provide theoretical basis for clinical individualized drug use. Methods:A total of 149 patients with aplastic anemia trea-ted with cyclosporin A as the main therapeutic drug were selected, and after 3-day treatment, the blood concentration of cyclosporin A was detected by an HPLC-UV method 10 minutes before the administration and 2 hours after the administration. The liver and kidney function were measured at the same time. The correlation between the different concentration of cyclosporine A and the change of liver and kidney function was analyzed. Results:All the patients were monitored cyclosporine A blood concentration with 1236 samples, and 34 patients (22. 82%) were with drug-induced liver injury and 51 patients (34. 23%) showed drug-induced kidney toxicity. The average C0 of liver injury patients was (297. 92 ± 74. 14) μg·L-1 , and C2 was (944. 47 ± 148. 47) μg·L-1 , while the average C0 of kidney injury patients was (311. 41 ± 52. 80)μg·L-1, and C2 was (926. 25 ± 136. 02) μg·L-1. The function indices of liver (ALT, AST, TBIL) and kidney (SC, BUN, UA) were significantly higher than those in the normal group (P<0. 05), and the blood concentration of cyclosporin A was significantly correlated with the liver,and kidney function. Conclusion:There is a certain correla-tion between cyclosporine A -induced toxicity and its blood concentration and C2 may be a more valuable predictor for drug -induced liver injury.

It has been found by sorting out and analyzing ancient and modern doctors’ green tortoise exploring point acupuncture manipulation that ancient and modern doctors use Xu Feng's manipulation as the foundation and make some innovations on that b asis and according to their own clinical experiences. The clinical application range of different doctors’ green tortoise exploring point acupuncture manipulation is proposed by summarizing recent over 10 years’ clinical reports and the authors’ clinical practice. It is considered that the shortcomings of green tortoise exploring point acupuncture manipulation are lack of manipulation standardization and modern mechanism study and that manipulation standardization should be closely connected with clinical practice for further application and popularization.

Bronchiolitis is the main cause of wheezing episodes in infants under 2 years old.Most of them are caused by virus infection.Most of the children with bronchiolitis can recover after clinical treatment, but some of them may have recurrent wheezing or even asthma.There are many risk factors and complicated pathogenesis of recurrent wheezing after bronchiolitis.Risk factors mainly include: susceptible gene, virus type infected in the first wheezing, atopy, exposure to school-age siblings, tobacco exposure, family history of asthma, increased specific IgE, high blood eosinophils count, etc.In this paper, the risk factors of recurrent wheezing after bronchiolitis are introduced as follows.
