Objective:To investigate the mechanism of immunoglobulin Y antibodies(IgY) against tumour necrosis factor alpha(TNF-α) and Interleukin-1beta(IL-1β) in treating allergic bronchial asthma through nebulization inhalation.Methods:The allergic bronchial asthma model was established with Hartley guinea pig by ovalbumin nebulizating inhalation.The animals were randomly divided into 4 groups: normal control group(group A)，allergic bronchial asthma group(group B),0.1% anti-TNF-α and IL-1β IgY treating group(group C),1.0% anti-TNF-α and IL-1β IgY treating group (group D).The animals were killed after treatment being accomplished for 2 h,4 h,8 h,24 h and the lungs were made pathological,which were then stained by hematoxylin-eosin(H.E.).The bronchoalveolar lavage fluid (BALF) was collected and the deposited cells were stained by Wright's.Results:①The histological appearance of lung: In group B the histological structure of alveolar ducts and alveolar walls was damaged,the alveolar space was full of transudate and lots of alveolar epithelial cells and leucocytes.The pulmonary interstitial edema,inflammatory cells infiltration,distorted or dilated capillaries and reducing capillary numbers of effective blood stream were observed in alveolar walls.In group C and group D the damage degree of alveolar ducts and alveolar wall was slighter than that in group B and there were few inflammatory cells in alveolar space.In bronchial lumen and pulmonary alveoli the sticky mucus plug was obviously less in group C and group D than in group B.Moreover,inflammatory cell infiltration was seldom observed aroud bronchia,and restoration of bronchial tunica mucosa epithelium was obviously observed in group C and group D.②The cytology appearance of BALF: In group C and group D the numbers of eosinophils,neutrophils,lymphocytes were significantly fewer （2 h,4 h,8 h,P＜0.05）,however,the number of macrophage was significantly more（2 h,4 h,8 h,P＜0.05）than in group B.Conclusion:The anti-TNF-α and IL-1β IgY can obviously alleviate pathological extent of inflammatory reaction in allergic bronchial asthma of guinea pigs by nebulization inhalation therapy.The therapeutic effect of anti-TNF-α and IL-1β IgY between 0.1% and 1.0% concentration is not obvious difference for pathology changes.

Objective:To investigate the influence of histamine on intedeukin(IL-2) production and proliferation of CD4+ T lymphocytes and CD8+ T lymphocytes.Methods:Density gradient centrifugalization and absorption technique were respecitively applied to detach peripheral blood mononuclear cells(PBMC) and peripheral blood lymphocytes(PBLC). CD4+ and CD8+ T lymphocytes divided with anti-CD4+ and anti-CD8+ antibody were cultured in vitro. IL-2 levels in supernatant were quantified by enzyme-linked immunosobent assay (ELBA), and proliferation index were measured by MTT methods. Results:IL-2 levels in supernatant and proliferation rate of CD4+ and CD8+ T lymphocytes treated with histamine were significantly lower than those of their corresponding un-stimulated controls(P

Objective To evaluate the effect of oxytocin on Tp-e and QTc interval during caesarean section under spinal anesthesia in healthy puerperas. Methods Forty ASA Ⅰ puerperas were selected and allocated to receive oxytocin intravenous bolus group (group-IB) or oxytocin continuous infusion group (group-CI) with 20 puerperas in each by random digits table. An intravenous bolus of 5% glucose 5 ml and 5 U oxytocin was administered after delivery a 55-60 s period. A continuous infusion of 5% glucose 5 ml and 5U oxytocin was administered after delivery a 10 min period. Measured the QTc interval,Tp-e interval,mean arterial pressure (MAP) and beart rate ( HR ) pre-operatively, then 1,3 and 5 ain after spinal anesthesia, and at least 1,3,5 and 10 min after oxytocin injection. Results In group-IB:HR was fast 1 min after oxytocin injection compared with pre-operatively [(89 ± 13) beats/min vs. (73 ± 12) beats/min] ,MAP was decreased [(69 ± 12 ) mm Hg ( 1 mm Hg= 0. 133 kPa ) vs. ( 82 ± 13 ) mm Hg] and QTc interval was prolonged [(426 ±21 ) ms vs. (405 ± 18 ) ms] (P ＜ 0.01 ); but Tp-e interval was prolonged 1,3,5 min after oxytocin injection compared with pre-operatively (P ＜ 0.01 or ＜ 0.05 ). Conclusions Single large dose of oxytocin intravenous bolus (5 U) can prolong QTc interval and Tp-e interval in healthy puerperas, and Tp-e interval can exact predict the occurrence of ventricular arrhythmias. The risk-benefit balance of oxytocin bolus during caesarean delivery should be discussed with women with a history of long QT syndrome.

Objective To evaluate the efficacy and advantages of the technique by combined PCNL and retrograde intrarenal surgery (RIRS) in a second stage to treat the complex renal stones in solitary kidney cases.Methods PCNL most with a single 18-24 F tract was performed first and RIRS was carried out at a second stage in solitary kidneys of 21 patients,of which congenital in 14.3％ (3 cases),contralateral nephrectomy in 42.8％ (9 cases),and functional solitry kidneys in 42.8％ (9 cases).Of the 21 patients,the average age was 45 years with 15 males and 6 females.The stones were 8 multiple,6 partial staghorn,and 7 complete staghorn with a mean size of 4.6 (3.8-6.8) cm.Results Of the 21 PCNL cases,a single tract,double,triple tracts were established in 18 (85.7％),2 (9.5％),1 (4.8％) cases,respectively.Mean operation time of PCNL was 95 (45-175) min.After 1 day of PCNL,all case had residual stones with a mean size of 1.9 (1.0-3.5) cm.Two case occurred fever after PCNL and one case presented bleeding resolved by selective renal artery embolization.The mean operation time of RIRS was 72 (35-95) min.Stone-free rate after RIRS was 85.7％ (18/21).The final stone free rate increased to 95.2％ (20/21) after one case received a second-look PCNL and two cases accepted ESWL.Two cases occurred fever and steinstrasses after RIRS resolved by rigid ureteroscopy.At the 3 months follow-up,renal function became stable,improved and worse in 71.4％ (n=15),23.8％ (n=5),and 4.8％ (n=l) of patients.Conclusions PCNL combined with RIRS could be an effective and safe option for complex stones in solitary kidneys with less bleeding,reduced tracts,minor complications and good renal function preservation.

Objective To evaluate the effects and complications of percutaneous nephrolithotomy (PCNL) in the treatment of renal stone after repeated extracorporeal shockwave lithotripsy (ESWL).Methods Forty-four patients who had a history of repeated ESWL (treatment group) and 50 patients with-out surgical intervention (control group) were submited to PCNL,and clinical data was documented in details and analyzed.Results The time to establish access in treatment group and control group was (11.8 ± 4.1) min and (10.9 ± 2.5) min,respectively,and there was no significant difference (t =1.308,P =0.194).The time to extract stone in both groups was (92.0 ± 13.5) min and (66.6 ± 17.6) min,respectively,and there was significant difference (t =7.776,P =0.000).The operative time in treatment group was (113.9 ± 12.0) min,which was longer than that in control group with (87.6 ± 13.6) min (t =8.354,P =0.000).The clearance in both groups was 81.8％ and 94.0％,and there was no significant difference (x2 =3.361,P =0.067).The was no death or other severe complication in both groups.Conclusions The operation time in treatment group was longer than that in control group,and there was no significant difference in clearance and complication rate.Thus it was safe and effctive to perform PCNL in these patients with a history of failed repeated ESWL.

Objective To compare the efficiency between mini-percutaneous nephrolithotomy (MPCNL) and extracorporeal shock wave lithotripsy (ESWL) for monotherapy of renal calculi in infants less than 3 years.Methods Forty-six infants were treated with either SWL (22 infants) or MPCNL monotherapy (24 infants).The mean age was (22.6 ± 8.7) months vs (23.5 ± 6.6) months and the stone size was (21.4 ± 3.5) mm vs (21.7 ± 1.7) mm,and there were no significant difference.Results For MPCNL,mean operating time was (76.2 ± 23.4) min and mean hospital stay was (14.13 ± 5.8) d.The stone-free rates were 84.0％ (21/25) after first session and 96.0％ (24/25) after second-look procedure.Postoperative fever happened in 4 (16.0％) cases.Hemoglobin drop was (8.5 ± 4.4) g/L and no one needed blood transfusion.For ESWL,the stone-free rate were 31.8％ (7/22) after first session and 86.3％ (19/22) after second session for 11 infants (50.0％).Mean hospital stay was (6.6 ± 2.3) d and 10 cases (45.5％)had complications.Hemoglobin drop was (10.6 ± 12.7) g/L.MPCNL was lower than ESWL in complications rate and re-treatment rate,and the stone-free rate was higher,but the hospital stay and operation time was longer (P ＜ 0.05).GFR revealed improve or stable after operation in both groups.Conclusions For a higher success rate,lower complication rate and re-treatment rate,MPCNL was an effective option for the management of relatively larger stones in children (even in infants).

Objective To investigate the treatment of urinary tract obstruction after kidney transplantation, and to introduce the novel ‘antegrade percutaneous urinary tract throughout guidance technique’ with guide wire in selected patients. Methods 43 cases of renal transplantation patients due to urinary tract obstruction (ureteral stenosis and hydronephrosis in 24 cases, urinary calculi with or not ureteral stenosis in 19 cases) received endourological treatment. Retrograde pathway was tried firstly, if failed, antegrade pathway was adopted with‘antegrade percutaneous urinary tract throughout guidance technique’, 18 Fr percutaneous tract was established if necessary, endoscopy was needed in antegrade or combine with retrograde pathway. Results Of the 43 patients, 9 (20.9 %) patients were managed directly through the retrograde ureteroscopy, 28 (65.1 %) patients were managed with anterograde percutaneous technique in 18 Fr tract, 6 (14.0 %) patients were treated with ‘antegrade percutaneous urinary tract throughout guidance technique’. Operation time was (72.0 ± 16.0) (45 ~ 95) minutes. Postoperative stone clearance rate of 89.5 % (17/19). Of 32 cases with ureteral stricture, 6 (6/32, 18.8 %) cases were cured after one time of dilation and JJ stent indwelling for 2 months, 18 (56.3%) cases with stable hydronephrosis after 2-3 times of dilation and JJ stent indwelling, 5 cases (15.6 %) needed long-term repeated stent indwelling for drainage, 3 (9.4%) cases required nephrostomy tube drainage. Conclusion Minimally invasive treatment of urinary tract obstruction after renal transplantation is effective. Antegrade percutaneous urinary tract throughout guidance technique provided a powerful guarantee for retrograde operation and avoided the bleeding risk following percutaneous renal surgery, when combined with flexible ureteroscopy, urinary calculi in patients with kidney transplantation can be effectively managed with little trauma.
