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.

OBJECTIVETo observe the therapeutic efficacy of Danggui Buxue Decoction No.1 in treating patients of non-small cell lung cancer (NSCLC) at the peri-operational stage and its impact on the patients' immune function.

METHODSEighty-two NSCLC patients were randomly assigned to two groups equally, the control group and the test group, they were given conventional treatment, while to the test group, DB1 were given additionally. The observation was conducted by testing the changes of T-lymphocyte subsets, natural killer (NK) cell activity, serum levels of immunoglobulin (IgA, IgM, IgG), interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-alpha), cytokeratin fragment 19 (CYFRA21-1) and carcinoembryonic antigen (CEA) in NSCLC patients before and after administration of DB1, and analyzing the patients' general condition.

RESULTSThe level of CD3(+), CD4(+), the ratio of CD4 and CD8(+), IgA, IgM, IgG and IL-2 decreased in patients with NSCLC on day 1 after operation, and the level of CD8 and TNF-alpha increased compared to pre-operation. While the levels of CD3(+), CD4(+), CD4 /CD8(+), NK cell activity, serum IgA, IgM, IgG, IL-2 began to elevate, CD8 and TNF-alpha levels began to decline in patients administered with DB1 on day 3 after the operation, earlier than patients who did not use the decoction. The level of CYFRA21-1 and CEA, was immediately decreased after operation in both groups.

CONCLUSIONSApplying DB1 to NSCLC patients at an early post-operational stage could alleviate the impairment and accelerate the recovery of immune function of patients to enhance their immunity. DB1 also shows an anti-tumor action to a certain degree.

OBJECTIVETo investigate the changes of gene expression file in transitional cell carcinoma of bladder after hepatocyte cell adhesion molecule(hepaCAM) overexpression.

METHODSAffymetrix Human Genome U133 Plus 2.0 Array was used to investigate the changes of gene expression profile between adenovirus-green fluorescent protein(GFP) -hepaCAM group and GFP group in transitional cell carcinoma of bladder EJ cells.Significant Analysis of Microarray(SAM) was used to screen the differentially expressed genes, DAVID software was used to conduct gene ontology analysis and wikiPathway analysis based on the differentially expressed genes. Reverse transcription-polymerase chain reaction and Western blot were applied to verify microarray data.

RESULTSCompared with the GFP group, a total of 2469 genes were up-regulated or down-regulated by more than 2 times in the GFP-hepaCAM group. Among these genes, 1602 genes were up-regulated and 867 were down-regulated.Most of the differentially expressed genes were involved in the function of cell proliferation and cell cycle regulation. The mRNA expressions of nibrin, liver kinase B1, and cyclin D1 detected by reverse transcription-polymerase chain reaction in three different bladder cancer cell lines were consistent with the microarray data.The protein expressions of nibrin and liver kinase B1 in these three cell lines measured by Western blot were consistent with the mRNA expression.

CONCLUSIONSHepaCAM can alter the gene expression profile of bladder cancer EJ cells. The well-known anti-tumor effect of hepaCAM may be mediated by regulating the gene expression via multiple pathways.

Objective: To observe the difference of the effect of low-frequency electroacupuncture (EA) on blood lipids between male and female patients with simple obesity due to damp induced by spleen deficiency. Methods: Eighty patients with simple obesity were recruited, including 37 males and 43 females, to receive low-frequency EA by selecting Yinlingquan (SP 10), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4), with needles retained for 30 min. The treatment was given once a day, 10 sessions as a treatment course, for 2 courses in total. The contents of body fat percentage (F%), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood glucose (Glu) and adiponectin (ADPN) in serum were observed to see the changes, and the two groups were compared and analyzed. Results: After the treatment, F%, and serum contents of TC, TG, LDL, Glu and ADPN dropped significantly in the two groups (P<0.05 or P<0.01) and the serum content of HDL increased significantly in male group (P<0.05). The decrease of F% in female group was more significant than that in male group (P<0.01); the decrease of ADPN in male group was more significant than that in female group (P<0.05). Conclusion: EA can regulate the disordered blood lipids in male and female patients with simple obesity, with certain differences between genders. The decrease of subcutaneous fat content is more significant in females than that in males, while the decrease of ADPN is more significant in males.

Objective:To study confirm whether curcumin could inhibit the proliferation of CD44+colon cancer cells. In this study. Methods: MTT method was used to test the proliferation inhibition effects of curcumin against colon cancer cells. And Real-time PCR and Fluorescence-activated cell sorting (FACS) were used to determine CD44 expression level in colon cancer cells after treated with curcumin. Then we used Magnetic-activated cell sorting ( MACS) method to separate CD44 positive and negative cells. And we compared the proliferation inhibition effects of curcumin against these two kinds of cells. Results: Curcumin could inhibit the proliferation of HCT116 and HT-29 colon cancer cell lines. The expression level of CD44 could also be down-regulated after the colon cancer cells were treated with curcumin. Conclusion: Curcumin could inhibit the proliferation of CD44+colon cancer cells. Thus it was suggested that crcumin might have the effect to inhibit the proliferation of colon cancer stem cells and might be used as a promising agents to prevent the relapse and metastasis of colon cancer.

Objective To study the predictive value of umbilical cord blood regulatory T cells (Treg) for bronchopulmonary dysplasia (BPD) in preterm infants. Method From June 2017 to December 2018, premature infants with gestational age less than 32 weeks admitted to NICU of our hospiatal were prospectively selected. The umbilical cord blood was collected at birth to examine the Treg amount. The infants were assigned into BPD group and non-BPD group according to the diagnosis at discharge. The differences of Treg amount between the two groups and different degrees of BPD were analysed. Result A total of 124 premature infants (GA<32 weeks) were admitted, including 41 cases in BPD group (mild, n=18;moderate, n=14; severe, n=9) and 83 cases in the non-BPD group. The BPD group had GA of (29.6 ± 1.1) weeks and birth weight (BW) of (1128 ± 135) g. The non-BPD group had GA of (29.8 ± 1.1) weeks and BW of (1316 ± 180) g. The birth weight, 1min and 5min Apgar scores in BPD group were lower than the non-BPD group (P<0.001). The BPD group had higher incidence of respiratory distress syndrome, longer duration of mechanical ventilation (MV) and oxygen inhalation(P<0.001) than the non-BPD group. The MV duration and oxygen inhalation duration in the severe BPD group were significantly longer than the moderate and mild BPD groups, and the duration in the moderate group was longer than the mild group (P<0.001). The number of Treg in cord blood in the BPD group [(1.43 ± 0.06) × 105 cells/ml] was significantly lower than the non-BPD group [(2.57 ± 0.09) × 105 cells/ml], and the difference was statistically significant (P<0.001). Multivariate Logistic regression analysis showed that a significant decrease in the number of Treg was a risk factor for BPD in premature infants (OR=0.000, 95％CI 0.000 ～ 0.012, P=0.009). The number of Treg in umbilical cord blood was negatively correlated with the severity of BPD. The area under the ROC curve showed that the cut-off value was 1.95 × 105 cells/ml, with Youden index 0.613, sensitivity 85.4％ and specificity 75.9％. Conclusion The number of cord blood Treg cells may be a useful biomarker for predicting BPD in premature infants.

Upon glucose elevation, pancreatic beta-cells secrete insulin in a Ca(2+)-dependent manner. In diabetic animal models, different aspects of the calcium signaling pathway in beta-cells are altered, but there is no consensus regarding their relative contributions to the development of beta-cell dysfunction. In this study, we compared the increase in cytosolic Ca(2+) ([Ca(2+)]i) via Ca(2+) influx, Ca(2+) mobilization from endoplasmic reticulum (ER) calcium stores, and the removal of Ca(2+) via multiple mechanisms in beta-cells from both diabetic db/db mice and non-diabetic C57BL/6J mice. We refined our previous quantitative model to describe the slow [Ca(2+)]i recovery after depolarization in beta-cells from db/db mice. According to the model, the activity levels of the two subtypes of the sarco-endoplasmic reticulum Ca(2+)-ATPase (SERCA) pump, SERCA2 and SERCA3, were severely down-regulated in diabetic cells to 65% and 0% of the levels in normal cells. This down-regulation may lead to a reduction in the Ca(2+) concentration in the ER, a compensatory up-regulation of the plasma membrane Na(+)/Ca(2+) exchanger (NCX) and a reduction in depolarization-evoked Ca(2+) influx. As a result, the patterns of glucose-stimulated calcium oscillations were significantly different in db/db diabetic beta-cells compared with normal cells. Overall, quantifying the changes in the calcium signaling pathway in db/db diabetic beta-cells will aid in the development of a disease model that could provide insight into the adaptive transformations of beta-cell function during diabetes development.
