Aim To isolate and characterize the human circulating fibrocytes from human peripheral blood and explore the effects of curcumin on human circulating fi-brocytes.Methods The cells were isolated and puri-fied by density gradient centrifugation,and identified by flow cytometry and immunocytochemistry .Then , CCK-8 and flow cytometry were used to study the effect of curcumin on the proliferation as well as COL I ex-pression of human circulating fibrocytes,respectively. Results After being isolated the cells expressed CD34,CD45 and COLⅠ,among which 79.7% were both CD45 and collagen I positive,typical of human circulating fibrocytes.Curcumin could exert regulatory effects on proliferation of human circulating fibrocytes. Exposure of the cells to curcumin for as short as 24 hours promoted their growth,while prolonged treatment (72 h ) significantly inhibited cell propagation and downregulated the COLⅠ levels,best manifested at a concentration as high as 20 μmol · L-1 .Conclusion The proliferation of cells and COLⅠexpressions can be effectively inhibited by curcumin with the prolonged action period and high concentrations.

Objective To discuss the diagnostic value of serum procalcitonin (PCT) and C-reactive protein (CRP) in children suffering from malignant solid tumor with concurrent infection and in tumor progressing stage.Methods A total of 94 cases of malignant solid tumor at Department of Pediatrics,Beijing Tongren Hospital,Capital Medical University from March to August 2016,were collected and divided into 2 groups:infection group (n =17) and non-infection group (control group,n =77).Meanwhile,the control group were further divided into stable tumor group (n =48) and the advanced tumor group (n =29).All of the serum specimens were detected for PCT and CRP levels.PCT and CRP levels were compared and statistically analyzed among different groups.The median(four digit spacing) was used to describe the data.Results PCT level significantly increased in the infection group [0.67 (1.35) μg/L] compared with that of the control group [0.09 (0.08) μg/L],and the difference was statistically significant (Z =-6.371,P =0.000).CRP level significantly increased in the infection group[95.00(93.42) mg/L] compared with that of the control group[1.99 (12.49) mg/L],and the difference was statistically significant (Z =-5.555,P =0.000).During diagnosing infection,the area under the receiver operating characteristic curve (ROC curve) of PCT was 0.995(95％ CI:0.987-1.000),and the area under the ROC curve of CRP was 0.932(95％ CI:0.876-0.988);when the cutoff value of PCT was 0.468 μg/L,the sensitivity was 76.5％,and the specificity was 100.0％;when the cutoff value of CRP was 10.17 mg/L,the sensitivity was 88.2％,and the specificity was 72.7％.Compared to stable tumor group,PCT level of advanced tumor group significantly increased[0.12 (0.08) μg/L vs.0.07 (0.06) μg/L],and the difference was statistically significant(Z =-2.886,P =0.004);CRP level of the advanced tumor group sig nificantly increased [10.34 (27.84) mg/L vs.1.02 (2.12) mg/L],and the difference was statistically significant (Z =-4.862,P =0.000).During diagnosing tumor progression,the area under the ROC curve of PCT was 0.697 (95 ％ CI:0.572-0.823),and the area under the ROC curve of CRP was 0.832(95％ CI:0.738-0.926);when the cutoff value of PCT was 0.094 μg/L,the sensitivity was 72.4％,and the specificity was 66.7％;when the cutoff value of CRP was 2.39 mg/L,the sensitivity was 72.4％,the specificity was 72.9％.Correlation analysis showed that the PCT and CRP levels were positively associated with tumor progression,and the correlation of CRP (r =0.558,P =0.000) was much higher than that of PCT (r =0.331,P =0.003).Conclusions Both serum PCT and CRP are effective indicators in diagnosing tumor with concurrent infection.PCT is better in diagnosing infection than CRP,and is less influenced by tumor.CRP is a better way to identify whether tumor was in progress than PCT.Joint detection of 2 indexes in identification of children suffering from malignant solid tumor with concurrent infection and in progress has practical value for the diagnosis and treatment.

Objective The aim of this study was to investigate how different concentrations of dextran sulfate sodi-um ( DSS) influence the establishment of mouse model of inflammatory bowel disease ( IBD) and the effect of DSS on the expression of colitis-associated immune factors.Methods The DSS solution in different concentrations (3%, 5%, 7%) were given to male C57BL/6J mice to generate mouse inflammatory bowel disease model.The IBD mice were observed by defecation characteristics, body weight, and survival time.The animals were sacrificed at 6 days after the start of DSS drinking.The general appearance of colons was observed and scored.Moreover, the pathological changes of the colon were examined and analyzed by routine histology.The expression of immune factors in the spleen was detected by real-time PCR.Results The mice in the 3%, 5%, 7% DSS groups developed murine colitis.In addition, the incidence of IBD and mouse mortality rate was directly proportional to the increase of DSS concentration.Furthermore, the higher concentra-tion of DSS induced the expression of proinflammatory factors including TNF-α, IFN-γand IL-17A, but cause a decrease of anti-inflammatory factors such as IL-4, IL-10 and Treg-related transcription factor Foxp3.Conclusions Our data suggest that giving 5%DSS solution to C57BL/6J mouse is appropriate to efficiently establish a murine IBD model.This laid an important foundation for further studies of the pathogenesis of IBD, biological characteristics, and intervention factors.

Methods Three pieces of Topo Ⅱα-shRNA and three pieces of Topo Ⅱβ-shRNA were designed,synthesized and transfected into K562/AS2 cells by liposome. Expression level of Topo Ⅱα and Topo Ⅱβ mRNA were determined by real time fluorescence quantitative PCR. The expressions of Topo Ⅱα and Topo Ⅱβ protein were assayed with flow cytometer. Results After treated with Topo Ⅱα-shRNA or Topo Ⅱβ-shRN A for 24 hours,the expression level of Topo Ⅱα mRNA and Topo Ⅱβ mRNA protein in K562/AS2 cells decreased at most (78.22±0.01) %,(31.17±1.27) % (P <0.05),and (57.36±0.01)%,(23.98±1.22) % (P <0.05) respectively. Conclusion The expression of Topo Ⅱ gene can be down-regulated after infected with Topo Ⅱ-shRNA in K562/ AS2 cell line.

This article was aimed to study the effect of Baohe granules for patients with chronic heart failure (CHF) of traditional Chinese medicine (TCM) syndrome and the effect of gastrointestinal hormone secretion. Patients with CHF were used as the object of study. A total of 80 selected patients were divided into 2 groups. The control group was treated with western medicine anti-heart failure therapy. The treatment group was treated with the combination of Baohe granules. All patients were compared in aspects of TCM efficacy, symptom score and serum gastrin, motilin secretion after two-week medication. The results showed that both treatments can significantly improve the TCM syn-drome and symptom total score of CHF patients. And the effect of the treatment group with Baohe granules was bet-ter. The TCM single symptom integral was also obviously improved in the treatment group combined with Baohe granules, which included heart palpitations, shortness of breath, abdominal distension, and loss of appetite. The GAS and MTL levels of CHF patients were significantly increased in the treatment group. It was concluded that the treat-ment combined with Baohe granules can improve CHF patients with TCM syndromes, symptoms and gastrointestinal hormone secretion. Thus, it contributed to the stability of the disease condition. It can slow the disease progression and improve prognosis. So it is worth using widely in the clinical practice.
