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.

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.

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 To observe the effects of low dose irradiation (LDI) on autoiogous CIK cell proliferation, phenotype and killing activity in tumor patients, and to provide the evidence for clinical application of adoptive immunotherapy with CIK cells. Methods Peripheral blood mononuclear cells (PBMC) were separated from 10 patients with malignant tumor, and CIK cells were cultured with different cytokines. (1) After 10 d culture, C1K cells were irradiated with different doses as 30, 50, 80, 100 and 200 Gy of X-rays was also detected. The CIK cell proliferation and killing activity were measured with 3H-TdR incorporation assay and 3H-TdR release assay, respectively and the percentage variation of CD3 +CD56 + were measured with flow cytometry after 24 h. ( 1 ) Autologous CIK cells were irradiated with 80 mGy X-rays. At different culture time ( 12, 24, 48, 72 h) after irradiation, the killing activity was measured with 3H-TdR release assay. (3) The effect of 3d low dose irradiation of 80 mGy X-rays on thekilling activity of CIK cells was also detected. Results After the CIK cells were irradiated with different doses as 50, 80, 100, 200 mGy of X-rays, the CPM values were 20 048.6 ± 2332. 2 ( t = 2.2, P ＜0.05), 21 832.2 ±2975.9 (t=3.5, P＜0.01), 21 000.3 ±2451.1 (t=3.3, P＜0.01), 19908.1 ±2051.0 ( t = 2.2, P ＜ 0.05 ), respectively and the proliferation of CIK cells were significantly higher than that of control group. The CD3 + CD56 + cell percentage of 50, 80, 100 mGy groups were ( 30.3 ±3.8)% (t=2.3, P＜0.05), (32.3±3.4)% (t=4.2, P＜0.01), (29.742.9)% (t = 2.4, P＜0.05 ), respectively. The killing activity of CIK cells of 80, 100 mGy groups were 55.2 ± 5.0 ( t = 3.3, P ＜ 0.01 ), 52.8 ± 4.1 ( t = 2.3, P ＜ 0.05 ), respectively. The killing activity of CIK cells up-regulated significantly at 24 h, dropped to normal levels at 48 h and 72 h. After 80 mGy X-ray irradiation for 3 consecutive days, the killing activity of CIK cells at different time points were 55.2 ± 5.3 (t = 2.6, P ＜0.05),61.9 ± 4.4 (t = 4.7, P ＜0.01), 67.2 ±5.7 (t = 5.7, P ＜0.01) for 24, 48, 72 h,respectively. Conclusions LDI might have the hormesis effect on CIK cells.

Keratoacanthoma ( KA) is an epithelial neoplasm occurring in sun -exposed skin of the elder-ly.Two striking features of KA are its clinical behavior with spontaneous regression after rapid growth and its nos -ological position on the border between benignity and malignancy .The regression of KA may be associated with the hair follicle cycle,apoptosis and immune function of organism .This article summarizes physiological mecha-nisms such as Wnt/retinoic acid signalling cross -talk,the function of p53,bcl-2,bcl-xL and bak in apopto-sis,and the mechanism of action of several immune -related cells,that drives KA regression .It can provide theo-retical basis for us to select the method as well as time of the treatment in KA .

Objective To investigate the application value of virtual touch tissues quantization(VTQ)in the stages of type 2 diabetic nephropathy.Methods 120 cases of type 2 diabetes were divided into 3 groups according to urinary albumin excretion rate (UAER):diabetes without urinary albumin,diabetes with trace albuminuria and diabetes with mass albuminuria.The control group consisted 30 normal cases.VTQ was used to measure the renal shear wave velocity (SWV),then compare were made between the 4 groups.Besides,correlation analysis was made between SWV and UAER in diabetic nephropathy group.Results When compared SWV,there was no significant difference between diabetes without urinary albumin and control group (P =0.144),but there was significant difference between each 2 group of diabetes with trace albuminuria,diabetics with mass albuminuria group and control group (P ＜ 0.05).There was also significant difference between each 2 group of diabetes (P ＜ 0.05).The correlation coefficients for SWV and UAER in diabetes were 0.697(P ＜0.05).ROC analyses showed the area under curves for SWV diagnosis for diabetic nephropathy was 0.93.The best cutoff point,sensitivity and specificity were 2.43 m/s,85.7％ and 84.5 ％,respectively.Conclusions The renal SWV increases as the renal injury progresses,which also plays an important role in diabetic nephropathy stages.
