Recurrent respiratory tract infection (RRTI) is a common chronic respiratory disease of children.The pathogenesis is complex,etiology and treatment methods are varied.Probiotics are immune modulators with extensive clinical application.This paper reviewed the changes of intestinal microflora in children with recurrent respiratory tract infection and the mechanisms of probiotic treatment including intestinal flora regulation,intestinal mucosal barrier,stimulation of the growth of intestinal mucosa and immune regulation.

ObjectiveTo compare the correlation and agreement of international normalized ratio (INR) measured by INRatio coagulometer and standard laboratory venous blood measurement in order to judge the clinical application value of measuring INR by INRatio coagulometer.MethodsOne hundred who received warfarin were chosen randomly.Venous blood and finger capillary blood were taken simultaneously for measurement of INR by laboratory coagulation analyzer SYSMEX CA-7000 and INRatio coagulometer respectively.The correlation and agreement of INR results tested by the two methods were analyzed.Results When INR ≤5,there was a good correlation between INRatio coagulometer and laboratory coagulation analyzer SYSMEX CA-7000 (r =0.898,P =0.000).The mean bias of the two methods was 0.36 and INR measured by INRatio coagulometer were higher than those tested by laboratory coagulation analyzer SYSMEX CA-7000.By Bland-Altman,it showed a good agreement for 91.2％ (62/68) of the difference INR located 95％ the limited of agreement when the mean INR 1.60 - 3.50,and a bad agreement for only 50.0％(1/2) of the difference INR located 95％ the limited of agreement when the mean INR ＞ 3.50.ConclusionsIn the therapeutic range,INR measured by INRatio coagulometer shows a good correlation and agreement with INR measured by the established laboratory method.INRatio coagulometer can be used to monitor INR in the patients received oral anticoagulant therapy.

This study was aimed to observe effects of traditional Chinese medicine (TCM) treatment from lung on mRNA expressions of iNOS in lung tissues of rats with ulcerative colitis (UC). A total of 52 rats were used to estab-lish the UC rat model by using rabbit intestinal mucosal tissue allergenic model and TNBS-ethanol model (with the model success rate of 78%). Eight rats, which were randomly selected from 40 successfully modeled rats and the normal group, were used as the model group and the normal group before intervention (time point of week zero). The rest 32 successfully modeled rats were randomly divided into the model group, the western medicine (salazosulfapyri-dine) group, treatment from lung (Huang-Qi Jie-Geng, HQJG decoction) group, and treatment from intestine (Huang-Qi Huang-Lian, HQHL decoction) group, with 8 rats in each group. Another 8 normal rats were used as the control group. The intervention was given for 4 weeks. And the mRNA expression of iNOS was detected in week ze-ro, and four weeks after the treatment using real time-PCR. The results showed that in the acute phase of week zero, the mRNA level of iNOS in lung tissues of model group was significantly increased compared with that in normal group (P < 0.05); after 4-week treatment, compared with the normal group, the mRNA level of iNOS in the model group was significantly increased (P< 0.05). Compared with the model group, the mRNA level of iNOS in the treat-ment from lung group was significantly decreased (P < 0.01). It was concluded that NO which was catalyzed and synthesized by iNOS played an important role in pulmonary diseases. It can cause airway inflammation, edema, lung injury, and etc. Treatment from lung can alleviate the lung injury by inhibiting abnormal activation of iNOS.

Objective:Occult breast cancer (OBC) accounts for 0.3%-1.0%of all breast cancers. Because of the rarity of this dis-ease, its treatment and prognosis remain unclear. Our study evaluated the treatment outcomes and prognostic factors associated with OBC. Methods:A total of 82 patients diagnosed with OBC based on available criteria were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China, between January 1968 and June 2014. Except for 16 patients who were treated by needle biopsy or excisional biopsy only and were subsequently excluded, all of the cases reported were included in the study. Of the remaining 66 patients, one was male. Patient data, tumor characteristics, and treatment and outcome variables were evaluated. Overall survival (OS) and disease-free survival (DFS) were analyzed. A unicentric retrospective review of 66 patients with OBC was performed. Re-sults:The median follow-up was 75.5 months (7.0-328.0). No significant differences in OS and DFS were observed between patients who underwent mastectomy plus axillary lymph node dissection (Mast+ALND) and those who underwent breast conservation surgery (P>0.05). Univariate analysis revealed that nodal status is a significant prognosis factor of DFS (P=0.031). Conclusion:No significant difference in treatment outcomes between mastectomy+ALND and breast conservation surgery was observed. Nodal status may be an independent predictor of poor outcomes in OBC patients.

Objectives To assess the presence of autoantibodies directed against the epitopes of SmB and SmD in systemic lupus erythemotosus(SLE) as well as other different connective tissue diseases(CTDs) and analyze the clinical significance of them.Methods Polypeptides of SmB and SmD were designed with the animo acids sequence by the biologic technical software.The sera from different patients including 102 SLE,153 other CTDs and 54 controls were detected by ELISA with thesynthetic polypeptides.Results The positive percentage of anti-SmB and antiSm-D epitopes were higher in SLE than in other groups (P

Objective To compare the difference of the results of the total flavones acquired by three kinds of quantitative an-alytical methods in the People's Republic of China Pharmacopoeia(method A),Health Food Function Components and Health Indica-tors Inspection Specifications(method B),and Health Food Inspection and Evaluation of Technical Specifications(method C)respec-tively.

Purpose To investigate the expression of IGF-Ⅱand IGFBP-6 in co1orecta1 cancer,and to exp1ore the c1inica1 significance in co1orecta1 cancer. Methods IGF-Ⅱand IGFBP-6 were detected by immunohistochemistry and RT-PCR in 50 cases of co1orecta1 cancer(experimenta1 group)and 50 cases of the adjacent mucosa(contro1 group). Results (1)In the experimenta1 group,the ex-pression 1eve1 of IGF-Ⅱprotein and mRNA was significant1y higher than the contro1 group. The expression 1eve1s of IGF-Ⅱprotein and mRNA in co1orecta1 cancer were significant1y 1ower than the contro1 group.(2)The expression 1eve1s of IGF-Ⅱand IGFBP-6 were sig-nificant1y different between different tumor infi1tration depth,1ymph node metastasis,invasion depth and Duke’s stages( P<0. 05), but no difference between genders,age and the degree of tumor differentiation( P>0. 05). Conclusions There is a obvious corre1a-tion between of IGF-Ⅱ and IGFBP-6 in c1inica1 patho1ogica1 parameters in co1orecta1 cancer. Combined detection of the two markers may be the bio1ogica1 indicators of occurrence and prognosis of co1orecta1 cancer,and provide a new scheme for diagnosis and treatment of co1orecta1 cancer.

Objective To investigate the role of cAMP-PKA signal transduction pathway in the ischemie pleeonditioning-induced attenuation of ischemia.1eperfusion(ITR)injury in isohted rat hearts.Methods Fifty healthy adult SD rats weighing 300-350 g were anesthetized with intraperitoneal(IP)pentobarbital 50 meg/kg.Their he.arts were excised and perfused in a Langendorff apparatus with 37℃ oxygenated(95%O2-5%CO2)modified K-H solution at a constant pressure of 70 cm H2O,and randomly divided into 5 groups(n=10 each):group Ⅰ I/R;group Ⅱ ischemic preconditioning(IPC);groupⅢH89(PKA inhibitor);group Ⅳ PDTC(NF-κB inhibitor)and group Ⅴ db-cAMP.The experiment started after 10 min stabilization.The isolated hearts were tinct perfuzed for 30 min.followed by 60 min ischemia and 30 min leperfusion in group I/R(Ⅰ).Group IPC(Ⅱ)w88 subjected to 3 episodes of 5 min ischemia at 5 min intervals before I/R.Group Ⅲ and Ⅳ received 5 min perfnsion withH89 10 μmol/L and PDTC 100 μmol/L 3 times at 5 min intervals respectively before I/R.Group Ⅴ was peffnsed with db-cAMP 200 μmol/L for 30 min before I/R.Left ventricular developed pressure(LVDP)and ± dp/dtu were measured at stabilization period and 10, 20, 30 rain of reperfusion. Coronary flow (CF) was measured at stabilization period and 30 min of reperfusion and activities of LDH and creafinc kinase (CK) in the coronary effluent were determined. The myocardial specimens were obtained at 30 rain of reperfusion for determination of NF-κB-DNA binding activity (by EMSA) and expression of TNF-κ mBNA (by RT-PCR ) and p-CBEB (Ser133) (by Western blot). Results Compared with 1/R group, NF-κB-DNA binding activity and TNF-α mRNA expression were significandy decreased, ± dp/dt and CF were significandy increased, CK and LHD activities in the coronary effluent were significantly decreased in group IPC and db-cAMP (group Ⅱ , Ⅴ ) and p-CREB (Ser133) expression was significantly increased in group IPC, PDTC and db-cAMP (group Ⅱ , Ⅳ,Ⅴ ). Compared with IPC group, NF-κB-DNA binding activity and TNF-α mBNA expression were significantly increased, ± dp/dtmax, LVDP and CF were significantly decreased, CK and LDH activities were significantly increased in group H89 and PDTC (group Ⅲ, Ⅳ ) and p-CREB (Ser133) expression was significantly decreased in group H89(group Ⅲ ). Conclusion lschemic preconditioning can attenuate I/R injury in isolated hearts by inhibition of NF-κB-DNA binding activity via cAMP-PKA signal transduction pathway which reduces gene transcription of inflammatory cytokine.
