Objective:To identify the contributions of allergen to Th1 and Th2 by determined the levels of IFN-?,IL-4 and the transcription factors T-bet and GATA-3 in peripheral blood mononuclear cells(PBMC)of allergic asthmatics.Methods:①Plasma IFN-? and IL-4 were measured in 35 asthmatics and 32 healthy by ELISA,as well as the production of IFN-? and IL-4 by Dermatophagoides farinae(Df)-activated PBMC in asthmatics and 15 healthy controls.②Twenty-five asthmatics and 15 healthy persons were enrolled.The T-bet mRNA and GATA-3 mRNA expressing levels in PBMC were assayed by one step reverse transcription polymerase chain reaction(RT-PCR).Results:①The plasma IL-4 in the patients was significantly higher than that in healthy(t=3.265 9,P=0.001 7).The plasma IFN-? levels in asthmatics were no significantly different from that of the healthy(t=0.306 8,P=0.760 0).② In the condition of PBMCs activated by Df,the IL-4 and IFN-? levels in asthmatics were increased compared with healthy(t=3.564 4,P=0.001 0;t=3.350 0,P=0.002 0).③ There were some expression of the transcription factors T-bet and GATA-3 of PBMC in asthmatics and healthy.The expression of GATA-3 in the patients was significantly higher than that in healthy(t=2.274 3,P=0.028 0).The expression of T-bet and the ratio of T-bet/GATA-3 in the patients was no significant difference with the healthy(t=0.222 0,P=0.825 8;t=1.115 2,P=0.283 4).④ In the Df-activated PBMC,the expression of T-bet and GATA-3 in asthmatics were significantly higher than that of healthy(t=2.298 2,P=0.027 6;t=3.788 7,P=0.000 6),but the ratio of T-bet/GATA-3 was no significant difference with healthy(t=1.195 9,P=0.249 1).Conclusion:The production of Th2,Th1 cytokines and the expression of GATA-3 and T-bet in allergic asthmatics are both increased.It is suggested that the imbanlance of Th1/Th2 unsatisfactorily explain the pathogenesis of allergic asthma.

The problems in traditional imaging film and its reporting process were described.A virtual printing server network and a self-service printing service model of image film and its reporting model,established by improving the traditional imaging film and reporting process,could shorten the waiting time of patients after examinations,reduce the errors in imaging film reports,and improve the working efficiency of staff.

OBJECTIVE To investigate the protective effect of total saponins from stems and leaves of Panax ginseng (GSLS) on cisplatin (CDDP)-induced kidney damage in mice and its possible mechanism. METHODS Thirty-two male ICR mice were randomly divided into normal control group, CDDP group, and GSLS(150 and 300)+CDDP groups. GSLS was administered to mice by oral gavage once a day for 7 d. On the 7th day, a single injection of CDDP 20 mg·kg-1 was given 1 h after GSLS 150 and 300 mg·kg-1 before GSLS 150 and 300 mg·kg-1 continued to be given for 3 d. Blood urea nitrogen (BUN) and creatinine (CRE) , catalase (CAT) in renal tissue, reduced glutathione (GSH), tumor necrosis factorα(TNF-α) and interleukin 1β(IL-1β) of cisplatin induced mice were detected after 72 h. HE and PAS staining were used to observe the renal histopathological changes;While TUNEL and Hoechst33258 staining were employed to observe apoptosis in kidney tissues. RESULTS Compared with normal control group, CDDP group had a significant reduction in relative body mass (P<0.05), and the level of GSH and CAT in kidney tissues (P<0.05). The level of CRE, BUN, TNF-α, and IL-1βin serum and renal indexes significantly increased (P<0.05, P<0.01), especially BUN and CRE that respectively doubled and quadrupled. CDDP group developed glomerulus swelling, renal tubular expansion and epithelial cell necrosis. Trans?parent tube type of tube cavity appeared, the nucleus pycnosis disappeared, but renal interstitial edema and inflammatory cell infiltration appeared. There was a large amount of glycogen deposition and high expressions of TUNEL positive cells and Hoechst33258 positive cells. Compared with CDDP group, the levels of BUN and CRE in GSLS treatment group significantly decreased (P<0.05, P<0.01) in serum, glycogen deposition was reducted and apoptosis of renal tubular epithelial cells decreased in kidney tissues (P<0.05). The level of TNF-α, IL-1β(P<0.05) and the degree of renal tissue necrosis were significantly reduced (P<0.05) in CDDP+GSLS 300 group, but there was a significant increase in the level of CAT and GSH (P<0.05). CONCLUSION GSLS can protect against mouse kidney injury induced by cisplatin. The mechanism may be related to oxidation, reduced inflammation reaction and resistance to apoptosis.

We observed a rare case of invasive mucinous adenocarcinoma (IMA) with a lepidic-predominant pattern accompanied by pulmonary tuberculosis. An 85-year-old man with repeated cough and sputum was admitted to Xinhua Hospital. T-SPOT test result was 212 pg/ml (reference value of negative is < 14 pg/ml), Mycobacterium tuberculosis culture was positive, and tuberculin skin test (PPD) was negative (skin induration < 5 mm). The patient was treated with several courses of antibiotics and anti-tuberculosis treatments. Repeated chest CT scans showed disease progression. Bronchoscopy yielded negative results. PET-CT scans showed negative results. A percutaneous lung biopsy revealed mucin-secreting cells lining the alveolar walls. IMA with a lepidic-predominant pattern was diagnosed after invasiveness was found after experimental treatments. Simultaneous occurrence of pulmonary tuberculosis and lung cancer are common; however, the present case of IMA having a lepidic-predominant pattern and coexisting with active tuberculosis has not been reported yet.
