At present,diagnostic programs of food allergy in children mainly include medical history,skin prick test,detection of serum specific immunoglobulin E (sIgE) antibody,food challenge test,and so on.Among them,skin prick test and detection of sIgE antibody are used as primary screening tests with high diagnostic sensitivity while low specificity.Additionally,double-blind placebo-controlled food challenge test is the gold standard for the diagnosis,but it is faced with a potential risk of causing systemic allergic reactions,resulting in its rare application in clinic.Moreover,basophil activation test,as an in vitro test for allergen diagnosis,has significant value in diagnosis of food allergy in children due to its high specificity and safety.Besides,basophil activation test can also be used to evaluate the severity of food allergy in children,monitor immune therapy,detect trace allergens,and so on.

ObjectiveTo compare the clinical results of small surgical incision of bilateral spinous process and traditional open surgical incision in posterior single level lumbar interbody fusion,and assess the application value of the small surgical incision of bilateral spinous process in posterior single level lumbar interbody fusion.MethodsFrom December 2006 to June 2008,70 patients with lower lumbar vertebral diseases underwent single segment posterior lumbar interbody fusion.Patients were randomly divided into small surgical incision of bilateral spinous process group(Hereinafter referred to as small incision group) of 36 cases and 34 cases of conventional open group.Small incision group included 20 males and 16 females with an average age of 52.0 years.Traditional open group included 16 males and 18 females with an average age of 53.2 years.Two groups of operative time,blood loss,postoperative drainage,X-ray projection operation frequency,hospital stay,complication rate,creatine phosphokinase (CPK) level,multifidus cross-sectional area,postoperative low back pain visual analogue scale(VAS),Oswestry disability index(ODI),interbody fusion rate were compared,respectively.ResultsAll of 70 cases were followed up for 12-24 months (average,16).There were no statistically differences in the operation time,the number of X-ray projection,complication rate,and fusion rate between the two groups (P＞0.05),but there were significant differences in blood loss,postoperative drainage,the first day and the third day of postoperative the level of CPK,postoperative multifidus muscle cross-sectional area,postoperative low back pain VAS,hospital stay,and postoperative ODI between the two groups(P＜0.05).ConclusionSmall surgical incision of bilateral spinous process and traditional open surgical posterior lumbar interbody fusion were satisfied with the efficacy,but small surgical incision of bilateral spinous process with less trauma,shorter hospital stay,and rapid postoperative recovery.

Objective To explore the molecular mechanisms underlying therapeutic responses of the anti-proteinuria drugs from the view of podocyte molecule. Methods Adriamycin (ADR) nephropathy was induced by a single tail intravenous injection of adriamycin. Lisinopril, prednisone and all-trans retinoic acid (ATRA) were administered once a day to the adriamycin-induced nephrotic rats at the first day after adriamycin injection respectively. Renal tissue samples were collected at day 3, 7, 14, and 28 after adriamycin injection respectively. The distribution, mRNA expression and protein expression of nephrin, podocin, CD2AP and ?-actinin-4 were examined by indirect immunofluorescence, real-time PCR and Western blotting, respectively. The interactions among nephrin and podocin, nephrin and CD2AP, as well as the nephrin phosphorylation were detected by immunoprecipitation, respectively. Results Compared to the control rats, 24 h urinary protein of the ADR rats increased significantly at day 14 (P

Objective To explore the molecular effect and interaction among nephrin, podocin, CD2AP and ?-actinin-4. Methods Firstly, the recombinant RNA interference (RNAi) plasmid-psiRNA-hH1GFPzeo, specifically targeting to the mRNA of nephrin, podocin, CD2AP or ?-actinin-4, was respectively tansfected into the mouse podocyte clone (MPC5) to each knockdown (KD) the expression of nephrin, podocin, CD2AP or ?-actinin-4. Molecular distributions were revealed by confocal microscopy, and the mRNA and protein expressions were detected with semi-quantitative RT-PCR and Western blotting. Results (1)In podocin KD group (siPod966 and siPod54), the mRNAs of podocin and nephrin were not detected, their protein decreased 92% and 79%, 82% and 67%, respectively. The mRNA and protein level of CD2AP increased 62% and 42%, 71% and 46%, respectively, whereas ?-actinin-4 did not change. In nephrin KD group (siNep492), the mRNA expression and protein level of nephrin were not detected, CD2AP increased 35% and 48%, respectively; and whereas podocin and ?-actinin-4 did not change. In CD2AP KD group (siCda744 and siCda21), the mRNA of expression CD2AP was not detected, and its protein level decreased 92% and 83%, the mRNA and protein of nephrin decreased 60% and 48%, 76% and 72%, respectively; podocin increased 38% and 22%, 56% and 44%, respectively; whereas ?-actinin-4 did not change. In ?-actinin-4 KD group (siAct1790 and siAct319), the mRNAs expression of ?-actinin-4 and nephrin decreased 69% and 58%, 64% and 49%, respectively; their protein level decreased 81% and 55%, 71% and 64%, respectively. However, the mRNAs of podocin and CD2AP increased 50% and 34%, 45% and 28%, respectively; and their protein level increased 64% and 46%, 65% and 42%, respectively. (2) With their expression change, the distributions of nephrin, podocin and CD2AP shifted evidently from the cell membrane surface to the nucleus circumference, whereas ?-actinin-4 showed no change, which was still localized in the cytoplasm and further extended to foot processes. Conclusion (1) Nephrin might more independently play a crucial role in the slit diaphragm complex. (2) Alpha-actinin-4 might interact direcdy or indirectly with nephrin, podocin and CD2AP. (3) The relationship among these podocyte molecules might not be spontaneous, either a single-directional or bi-directional reaction. (4) The normal localization of these podocyte molecules might depend on their normal expression quantity.

0.05) at any observed time points as compared with the controls.3.From day 7 after the adriamycin injection,VEGF protein reduced significantly(P

OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.

Objective:To evaluate the effect of continuing intervention on prophylactic application of antibiotics in sterile operation in urology department by clinical pharmacist to provide reference for the clinical prophylactic application of antibiotics. Methods:All cases of discharged patients underwent sterile operation in urology department of our hospital from July 2010 to June 2014 were divided into three groups according to the intervention time and methods: non-intervention group(n=141), stage Ⅰ intervention group(n=139), stage Ⅱ intervention group (n=162) and stage Ⅲ intervention group (n=137). The prophylactic application of antibiotics was statistically analyzed. Results:After the continuing intervention, the prophylactic application rate of antibiotics in the three inter-vention groups was decreased significantly from 100% before the intervention respectively to 34. 5%,18. 5% and 14. 6% after the in-tervention (P<0. 01). The rationality rate of prophylactic application was improved significantly from 36. 9% before the intervention respectively to 58. 3%, 63. 3% and 85. 0% after the intervention (P<0. 01). The course of prophylactic application was decreased significantly from (138.2 ±31.6)h respectively to (89.9 ±48.0)h,(72.8 ±32.5)h and(45.1 ±29.5)h (P<0.01) and the post-operative infection rate was decreased from 2. 8% respectively to 2. 1%,1. 8% and 1. 4%. Conclusion:The pharmaceutical interven-tion is feasible and valid to improve the rational prophylactic use of antibiotics in urological surgery.
