Objective To study the relationship between the T helper cells (Th22)/interleukin (IL)-22 and rheumatoid arthritis (RA) with interstitial lung disease (ILD), and to define the clinical significance of Th22 cells for RA. Methods The quantity of Th22 cells in the peripheral blood from 40 patients with RA (20 RA with ILD, 20 RA without ILD) were examined by flow cytometry, the level of IL-22 in the sera was detected by enzyme-linked immunosorbent assay (ELISA). Comparisons between groups were analyzed by t-test, rank sum test, and the correlation of parameters were tested by linear correlation analysis. Results The quantities of CD4+IL-22+ cells (Th22) in RA patients [(0.15 ±0.07)%] were significantly higher than normal controls [(0.09 ±0.05)%] (t=4.097, P<0.01), and IL-22 levels in RA patients [(83 ±7) ng/L] were significantly higher than normal controls [(61±5) ng/L] (t=13.057, P<0.01). The quantities of Th22 cells in RA-ILD patients [(0.18±0.07)%] were significantly higher than RA-NILD patients [(0.13±0.05)%] (t=2.919, P=0.008), and IL-22 levels in RA-ILD patients [(87±6) ng/L] were significantly higher than RA-NILD patients [(80±6)ng/L] (t=3.624, P=0.001). The quantities of Th22 cells were positively correlated with erythrocyte sedimentation rate (ESR), rheumatoid factor(RF) and 1.4 disease activity score (DAS)28 (r=0.336, 0.377, 0.577, P<0.05),and the level of IL-22 were also positively correlated with ESR and DAS28 (r=0.406, 0.576, P<0.05). Conclusion The quantities of Th22 cells and IL-22 level are increased in RA patients, especially in RA-ILD patients. The quantities of Th22 cells and IL-22 level are positively correlated with ESR and DAS28. It may play a certain role in RA especially in RA with ILD.

Objective To explore the relationship between peripheral Th17 cell number and chronic gastritis in Helicobacter pylori(H.pylori)-infected children.Methods Children were diagnosed as chronic gastritis by endoscopy.The degree and activity of inflammation were graded by histopathology examinations.The patients with both 13C urea breath test and urease test positive were diagnosed as H.pylori infection.The peripheral Th17 cell number was measured by flow cytometry and expressed as a ratio to total T cell.Results The Th17 cell number in HP group (chronic gastritis with H.pylori infection,n =33),non-HP group (chronic gastritis without H.pylori infection,n =24) and normal controls (n =15) were (1.55 ±0.30)%,(1.06 ±0.33)%,and (1.04 ±0.35)%,respectively.HP group included a statistically higher Th17 cell number than the other groups (all P < 0.05),while no obvious difference was found between non-HP group and controls (P > 0.05).According to the degree of inflammation,the chronic gastritis with H.pylori infection was categorized into non-apparent (n =10),mild (n =8),moderate (n =9) and severe (n =6) subgroups.The Th17 cell number in each subgroup was (1.64 ± 0.21)% (non-apparent),(1.61 ± 0.23)%(mild),(1.25 ± 0.29) % (moderate) and (1.75 ± 0.20) % (severe),respectively.The moderate group had a lowest Th17 cell number among 4 groups (P < 0.05).And significant differences did not exit in the other 3 groups (P > 0.05).The HP group patients with different inflammatory activity had a Th17 cell number of (1.23 ±0.25)% in nonapparent (n=15),(1.53 ±0.15)% in mild (n=6),(1.55 ±0.32)% in moderate (n=6) and (1.71 ±0.35)% in severe (n =6) subgroup,respectively.However,there were no significant differences among 4 subgroups (P > 0.05).Conclusions In the progress of chronic gastritis with H.pylori infection,Th17 cells may play a role as a double-edged sword by protecting and fighting against H.pylori infection and immunopathologic insults.This would provide more insights into the treatment of H.pylori infection.

Coronary artery lesions characteristics were compared among three groups .Results:Pairwise comparison showed , that occlusion lesion (33.3% ) and serious stenosis (70% ~94% ) lesion (34.8% ) in NSTEMI group were signifi‐cantly more than those of UAP group (14.9% ,8.1% ) respectively;the occlusion lesion and serious stenosis lesion of STEMI group were no significant difference compared with those of STEMI group , P>0.05 all;type C lesion 43.9% of NSTEMI group was significantly more than that of UAP group (27.0% ) and of STEMI group (31.6% ) respectively ( P<0.05 all);vulnerable plaque of NSTEMI group (56.1% ) was significantly more than that of UAP group (23.0% ,P<0.01) ,but was no significant difference compared with STEMI group (56.6% ,P> 0.05). Conclusion :Serious stenosis lesion ,type C lesion and vulnerable plaque of NSTEMI group are significantly more than those of UAP group ;in NSTEMI group , type C lesion is significantly more than ,and occlusion lesion occlusion le‐sion significantly less than that of STEMI group .

OBJECTIVE:To provide reference for ration use of TCM injection. METHODS:The utilization of TCM injections in 39 hospitals from Chongqing area during 2012-2014 was analyzed statistically in respects of consumption sum,DDDs,DDC and B/A. RESULTS:The total consumption sum of TCM injections increased slowly in 39 hospitals from Chongqing area during 2012-2014,increasing from 767 581 thousand yuan to 911 759 thousand yuan,with annual growth rate of 8.98%. Total sum of consumption sum of top 10 drugs was 1 326 019.7 thousand yuan,accounting for 51.11% of total. The consumption sum of Hong-hua injection and Shenxiong glucose injection always took up the first 2 places in those years. DDDs of Xuesaitong injection, Shenxiong glucose injection glucose,Honghua injection and Shuxuetong injection always took up the first 4 places in those years. DDC of Xuebijing injection and Kanglaite injection always took up the first and second places in those years. Among top 10 TCM injection in the list of consumption sum,most of B/A was lower than 1.00;B/A of Shuxuetong injection,Xingnaojing injection, Shenqiong glucose injection and Xueshuantong injection were close or equal to 1.00. Xuesaitong injection was the one that B/A>1.00 from beginning to end. CONCLUSIONS:Total use of TCM injection increased steadily and drug use relatively concentrated in 39 hospitals from Chongqing area during 2012-2014,and rationality of drug use by physicians had been improved gradually.

Objective To investigate the value of the multiple short tandem repeat (STR)amplification by fluorescence labeling polymerase chain reaction (PCR) combined with fusion gene bcr-abl mRNA expression for quantitative determination of chimerism and qualitative detection of bcr-abl transcripts,and to evaluate the status of engraftment and predict the outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods 5 relapse patients with CML after alIo-HSCT were dynamically investigated. Quantitative analysis of donor chimerism was performed by multiplex PCR amplification of STR markers and capillary electrophoresis with fluorescence detection, qualitative detection of bcr-abl transcripts was performed by RT-PCR. Results The donors alleles appeared in all of 5 patients on day 28 post transplant, and bcr-abl expression was negative. But 5 patients had unstable mixed ehimerism. (DC: 0~80.4 %) at the different time points after aIIo-HSCT and bcr-abl was positive. One of them kept eontinuely the mixed chimerism in the relapse of disease, and died after one year, and the other changed from MC to CC by intervention of clinical treatment. Reduction of donor chimerism were detected prior to the occurrence of graft rejection and disease relapse, while bcr-abl gene expression was positive. Conclusion The results of STR-PCR in the range of its sensitivity fully correspond with bcr-abl tests in patients with CML. The combination of STR-PCR with RT-PCR provides a highly sensitive and valuable tool for engraftment evaluation, graft rejection, relapse and predicting GVHD. Furthermore it can provide a basis for early intervention of clinical treatment, and can identify these patients at high risk with molecular or cytogenetic relapse after allo-HSCT.
