Objective To investigate the effect of Dectin-1 on the release of inflammatory factors interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in rat tracheal epithelial cells (RTECs) stimulated with heat-treated Candida glabrata (C.glabrata).Methods RTECs cultivated in vitro were randomly divided into three groups,including control group(RTECs + sterile normal saline),fungal stimulation group(RTECs + heat-treated C.glabrata),and inhibitor intervention group(RTECs + laminarin + heat-treated C.glabrata),cells were harvested after incubation for 0,2,4,6 hours respectively,cell survival rate was determined by MTT method,expression of Dectin-1 was analyzed by Western Blot,expression of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA).Results Heat-treated C.glabrata destroyed cell structure and reduced cell survival rate.At the beginning of the culture (0 h),cell survival rate,expressions of Dectin-1,IL-10 and TNF-α among three groups were all not significantly different(all P＞0.05).After incubation for 2,4,6 hours,expressions of Dectin-1,IL-10 and TNF-α in fungal stimulation group and inhibitor intervention group were both significantly higher than control group;expressions of Dectin-1,IL-10,and TNF-α in inhibitor intervention group was lower than fungal stimulation group(all P＜0.05).The expressions of IL-10 in inhibitor intervention group at 0 h and 2 h was not significantly different,expressions of Dectin-1,IL-10,and TNF-α in fungal stimulation group and inhibitor intervention group at different incubation periods were significantly different(all P＜0.05).Conclusion Dectin-1 is an important receptor for RTECs to recognize the heat-treated C.glabrata,it induces the release of IL-10 and TNF-α,and mediate the occurrence of inflammation.

Objective:To investigate the role of TSLP and NF-κB in the pathogenesis of adenomyosis.Methods:Immunohisto-chemistry was employed to detect the expression of TSLP and NF-κB p65 in the endometrial glandular cell and stromal cell of 35 adeno-myosis patients and 20 hysteromyoma patients as control , and analyze the correlation of the two proteins.The concentration of TSLP was measured by specific ELISA in the serum of healthy subjects besides of the patients with adenomyosis and hysteromyoma .Results:TSLP and NF-κB p65 were both positively expressd in the glandular cells and stromal cells of ectopic and eutopic endometrium of patients with adenomyosis , their expression was significantly higher than that of the control group ( P<0.01 ) , and the expression of TSLP and NF-κB p65 in ectopic endometrium was significantly higher than that in eutopic endometrium ( P<0.01 ).There was positive correlation between TSLP and NF-κB p65 in ectopic endometrium.The concentration of TSLP was higher in the serum of patients with adenomyosis.Conclusion:The TSLP is highly expressed in endometrial glandular and stromal cells of patients with adenomyosis , and there is higher level of TSLP in serum , and there is correlation between the expression of TSLP and NF-κB in ectopic endometrium.

Objective To investigate the diagnostic value of breast MRI in patients presenting with microcalcifications on mammography.Methods Eight four patients were retrospectively analyzed,who had mammographically detected BI-RADS (breast imaging reporting and data system) 3 to 5 microcalcifications and underwent breast MRI before surgical biopsy.All mammography and MR images were reviewed with BI-RADS.With histopathological diagnosis as golden standard,the sensitivity,specificity and accuracy of the two methods were calculated and compared with x2 test or Fisher exact test.The diagnostic efficacy of the two methods was compared with ROC curve.Results Pathologic examination revealed 91 lesions in 84 patients including 49 benign lesions and 42 malignant lesions.For 21 lesions of category 3 microcalcifications,the specificity of mammography and MR was 100.0％ (21/21) and 95.2％ (20/21),which had no significant difference (P=1.000).For 51 lesious of category 4,sensitivity,specificity and accuracy of mammography were 100.0％(23/23),0 and 45.1％(23/51).The corresponding values for MR were 91.3％(21/23),82.1％ (23/28) and 86.3％ (44/51).The difference for specificity and accuracy between the two methods was statistical significant(x2 value was 30.030 and 19.182,respectively,with P＜0.01),but not for sensitivity(x2=0.523,P=0.470).Nineteen lesions of category 5 were all correctly diagnosed on mammography and MRI.For all the 91 lesions,the sensitivity,specificity and accuracy of mammography were 100.0％(42/42),42.9％(21/49) and 69.2％(63/91),respectively.The corresponding values for MRI were 95.2 ％(40/42),87.8％(43/49) and 91.2％(83/91).There was significant difference for specificity and accuracy between the two methods (x2 value was 21.798 and 13.851,respectively,with P＜0.05),but not for sensitivity (x2=0.512,P=0.474).The areas under ROC curve for mammography and MR were 0.844,0.945(P＜0.01),for the estimation of the benign and the malignent.Conclusions Compared with mammography,breast MRI significantly improved the diagnosis of category 4 microcalcifications with increased specificity and accuracy.But for microcalcifications of category 3 and 5,MR didn't improve the diagnostic effect.

OBJECTIVETo really realize quality control of Chinese herb purifying process, near-infrared spectroscopy (NIRS) was used not only for fast monitoring quality-control index of the process, but also for fast judgment of absorption endpoint.

METHODThe purification process of Carthamus tinctorius extracts with nonionic macroreticular resin was selected as an example. HPLC was used as the reference method to determine the content of HSYA. Quantitative and qualitative detection modes of purification were developed by NIRS combined with partial least squares (PLS) and moving block of standard deviation (MBSD).

RESULTThe correlation coefficient of the calibration model was 0.999, and the RPD for calibration and validation were above 5, of 5.54 and 5.22, respectively. Based on acquisition spectra, absorption endpoint calculated by MBSD was close to that by HPLC, Only 1 min deviation.

CONCLUSIONThe method mentioned above is proved to be convenient, rapid and nondestructive, and is applicable for fast monitoring the content of HSYA and fast judgment of absorption endpoint in purifying process of C. tinctorius extracts.

Based on the policy framework , the premarital healthcare policy of Guangxi was analyzed from four aspects including policy background , process, content and actors.We analyzed the factors influencing this policy and their interactions , and discussed the important impact of Thalassemia prevention , multi-sectoral consensus and appro-priate premarital healthcare measures to the policy building and implementation .Then the lessons such as strengthe-ning the multi-sector cooperation , specifically making clear the pre-marital screening projects and implementing the“one-stop” service model were summed up in Guangxi province .Finally, combined with existing major problems , some policy recommendations were put forward including clarify the funding criteria and strengthen the premarital healthcare publicity in order to promote the sustainable development of premarital healthcare services .

Objective To analyze the differential proteomics of ASMC stimulated by wild IL-13 and mutant IL-13 and to investigate the relations of protein profiles of ASMC to asthma and possible targets for the treatment of bronchial asthma.Methods The total proteins of ASMC stimulated by wild IL-13 and mutant IL-13 were separated by immobilized pH gradient(IPG)-based 2-DE and the differentially expressed protein spots were identified by matrix assisted laser desorption-time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE detected approximately(840?21)spots on wild IL-13 samples and(892?17)spots on mutant IL-13 samples(n=3)and(685?19)spots matched.Six significantly differential proteins were subjected to MALDI-TOF-MS analysis and three of them were identified as stathmin 1,Ribosomal protein p~0 and NADH dehydrogenase.Conclusions ASMCs stimulated by wild IL-13 and mutant IL-13 present different proteomic profiles that may shed some light on the mechanism for the asthma causing effect of wild IL-13 and mutant IL-13.

The relationship between serum uric acid(SUA) and hypertension was investigated and the interactions of SUA with metabolic risk factors was assessed. Blood pressure and biomarkers features were evaluated for all the8 415 individuals from a community-based health examination survey in Xuzhou, and the statistical analysis was made. Raised blood pressure was associated with increased SUA concentration(P＜0.01). Age and high density lipoprotein cholesterol(HDL-C) significantly interacted with SUA(P for interaction=0.012 and 0.001, respectively). There is significant association between SUA and hypertension, which may be affected by age and HDL-C levels.
