Henoch-Schonlein purpura(HSP) is one of the most common blood capillary allergic disorder in children, and its pathogenesis has not been well explained. The studies show that the main mechanism of HSP is the abnormality of humoral immunity, and the role of IgA is emphaszed. Meanwhile, many agents such as changes in T cell function,participation of cytokine and mediators of intlammation, suscepti-bility gene and other factors also play an important role in the incidence of HSP. The pathogenesis of HSP can be better understood through extensive analysis of the immunology factors,genetic factors,and so on.

This paper introduces the design and implementation of Bluetooth wireless management and monitoring system. Combined with hospital information system, this system replaces the current monitoring system in hospital, and thus the efficiency of hospital can be improved.

Every stage of tumor initiation and development closely relates to immune regulation as tumor cells tend to evade attacks from immune system by employing the programmed death 1 (PD-1)/ programmed death-ligand 1 (PD-L1) interaction.Therefore,targeting the PD-1/PD-L1 pathway has become an attractive approach for cancer immunotherapy.Radiotherapy has long been considered a local tumor treatment modality and it is immune-inhibitory.However,accumulated evidence has shown that radiotherapy might enhance immune function by eliminating the tumor mass and has become a systemic tumor treatment modality.These observations indicate a strong rationale that the radiotherapy and anti-PD1 and anti-PD-L1 immunotherapy may work synergistically to provide a powerful anti-tumor effect.This review discusses current progresses,challenges and perspectives of this novel combination treatment modality.

Objective To investigate the prognostic value of modified Glasgow prognostic score(mGPS)in patients with gastric cancer.Methods The clinical data of 600 patients with gastric cancerwho underwent surgical treatment were retrospectively reviewed.These patients were divided into themGPS0 group,mGPS1 group,and mGPS2 group according to the standard of mGPS.Postoperative survivals and risk factors that may affect patient's prognosis were analyzed among the three groups.Results There were 46 (7.7%)cases,33 (5.5%)cases and 521 (86.8%)cases in the mGPS0,mGPS1 andmGPS2 group,respectively.Except for gender(P =0.203),age,BMI,CEA,CA199,CRP,Alb,TNM stageand mGPS affected the over all survivals and there were significant differences among the groups(P <0.01).Gender,age,BMI,CEA,CA199 and TNM stage affected the mGPS and there were significantdifferences among the groups(P <0.01).Multivariate analysis identified that age(OR,1.319,95% CI1.068,1.629,P <0.01),TNMstage(OR,2.909,95% CI 2.616,3.234,P <0.01)and mGPS(OR,1.845,95% CI 1.184,2.875,P =0.007)were correlated with the postoperative death rate and they wererisk factors of poor postoperative prognosis(P <0.01).Conclusion mGPS can be used as an early,simple and effective prognostic predictor of postoperative survival for patients with gastric cancer.

Objective To study the expression changes of matrix metalloproteinases (MMPs), protein kinase C (PKC) and nuclear factor-?B (NF-?B ) on the injured rabbit vascular smooth muscular cells (VSMC) transfected with tissue inhibitor of metalloproteinase-2 (TIMP-2) vector. Methods Lipofectin method was used to transfect TIMP-2 vector into VSMC, Western blot analysis to detect TIMP-2 peptides and zymography assay to determine MMPs. The activities of MMPs and NF-?B were detected by electrophoretic mobility shift assay (EMSA). The mRNA and protein expressions of PKC? were determined by RT-PCR and immunocytochemistry. Results The injured VSMC showed increased enzyme activity of MMP-2. There was very lower level expressions of PKC? and NF-?B in the normal VSMC but high in the injured VSMC. However, in injured VSMC transfected with TIMP-2 vector, the activity of MMP2/9 was suppressed and the expressions of PKC? and NF-?B decreased (P

Objective To investigate MRI examination methods and imaging manifestations of primary ureteral carcinoma, and to evaluate its clinical values when comparing with other diagnostic imaging facilities. Methods Eighty-seven cases of primary ureteral carcinoma who were operated within recent 8 years came into the study, among which, 35 cases had MRI examinations. For MRI examination, coronal heavy T2WI (water imaging) was performed to show the dilated ureter, then axial T2WI and T1WI were scanned at the obstruction level. 11 cases underwent additional Gd-DTPA dynamic contrast enhanced scans. The original pre-operative diagnostic reports of various imaging facilities were analyzed comparing with the results of operation and pathology. Results MRI showed ureteral dilatation in 33 of 35 cases, no abnormal appearance in 1 case, and only primary kidney atrophy post renal transplantation in 1 case. Among the 33 cases with ureteral obstruction, soft mass at the obstruction level was detected on axial scans in 32 cases. The lesions showed gradual and homogeneous mild to moderate enhancement on contrast MRI. The overall employment rate of imaging facilities was as follows: ultrasound (94. 3% ) , IVU (59. 8% ) , CT (52. 9% ) , MRI (40. 2% ) , and RUP (35. 6% ). The accurate diagnostic rate was as follows: MRI (91. 4% ) , RUP (80. 6% ) , CT (63. 0% ) , ultrasound (47. 6% ) , and IVU (11. 5% ). Conclusion Combination of MR water imaging and conventional sequences can demonstrate most primary ureteral carcinoma lesions and has a highest diagnostic accuracy among the current diagnostic imaging facilities. It should be taken as the first diagnostic imaging method of choice when primary ureteral carcinoma is suspected after ultrasound screening.

Objective To study the effect of emodin on biochemical indicators of drug‐induced intrahepatic cholestasis model and the interstitial cells of cajal (ICC) in bile duct and to explore the role of ICC and emodin in intrahepatic cholestasis .Methods Fif‐teen rats were randomly divided into drug‐induced intrahepatic cholestasis group ,emodin intervention group and control group(n=5) .Rat cholestatic hepatitis model and emodin intervention model were established .RT‐PCR and immunohistochemistry were used to detect liver function ,c‐kit mRNA and protein expression levels in drug‐induced intrahepatic cholestasis group ,emodin interven‐tion group and control group .Results The degree of liver dysfunction and bilirubin level in drug‐induced intrahepatic cholestasis group were significantly higher than those in control group(P<0 .05);the above indicators in emodin intervention group were sig‐nificantly higher than those in control group but lower than those in drug‐induced intrahepatic cholestasis group(P<0 .05) .The c‐kit mRNA expression located at 548 bp was observed in control group ,emodin intervention group and drug‐induced intrahepatic cholestasis group .Relative expression level of c‐kit mRNA in drug‐induced intrahepatic cholestasis group was significantly lower than that in emodin intervention group and control group (P<0 .05) .Meanwhile ,there was no significant difference in relative ex‐pression level of c‐kit mRNA between emodin intervention group and control group (P>0 .05) .Immunohistochemistry results indi‐cated that expression of c‐kit in drug‐induced intrahepatic cholestasis group was significantly lower than those in control group and emodin intervention group(P<0 .05) .Conclusion There may be close relationship between the forming process of drug‐induced in‐trahepatic cholestasis and decrease of ICC in bile duct .The therapeutic effect of emodin on intrahepatic cholestasis may be related with the number of ICC in bile duct or the positive effect on ICC.
