Objective To evaluate the surgical technique and clinical application of retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy with no suture of the incision. Methods Twenty-five patients who had upper urinary tract calculi with the course from 10 months to 6 years were enrolled.The size of the calculi was 1.2 to 3.1 cm in diameter.ESWL was ineffecative in 14 of the patients and ureteroscopic lithotomy failed in 2 of them.Then the 25 patients underwent retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy.Details of the procedure were presented. Results All the operations were successful in the 25 patients. The operations took 60 to 190 min with a mean time of 105 min.All the patients fully recovered with no complication observed during the 9~12 months' follow-up. Conclusions Retroperitoneal laparoscopy surgery with no suture of the incision has advantages of minimal invasive,safe,effective and rapid postoperative rehabilitation.The surgical procedure has a good prospect in the urologic clinical practice.

Aim To investigate the specific binding of folate conjugated PGA to FR-positive tumor cells.Method Folate-PGA and PGA were radiolabeled with 125I by the Iodogen method to examine the binding of PGA to FR positive HeLa cells and SKOV3 cells, or FR negative A549 cells. Results 125I-folate-PGA showed specific bound to HeLa cells and SKOV3 cells; Scatchard analysis of the data estimated the Kd of binding to be 0.11 nmol?L-1 and 0.25 nmol?L-1 respectively. 125I-folate-PGA showed virtually little specific binding to A549 cells which lack folate receptors. Conclusions folate-PGA displayed high affinity and good targeting activities for FR-positive tumor cells and the data warranted further studies for enzyme prodrug therapy.

To explore the clinical significance of serum cardiac troponin I (cTnI) for the detection of myocardial injury in children with Kawasaki disease (KD) in acute stage, the levels of serum cTn I, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactic dehydrogenase (LDH) and glutamic oxalacetic transaminase (GOT) were determined in 40 children with KD and 23 controlled children without heart disease, respectively. The results showed that the levels of serum cTn I and CK-MB in the KD group were significantly higher than those in the controlled group (P<0.001),while no obviously differences of CK, LDH and GOT were noticed between two groups (P>0.05). cTn I was more sensitive comparing to CK-MB for the detection of myocardial injury (P<0.05). It is concluded that the determination of cTn I and CK-MB will be available for the diagnosis of myocardial injury in children with KD in acute stage, and the determination of cTn I is more sensitivity and specificity comparing to CK-MB.

Objective To study the effect of dexmedetomidine and midazolam on hemodynamics and sedation in patients with nasal intubation.Methods Forty patients whose ASA grade Ⅰ-Ⅱ and anticipated difficult airway were randomly divided into dexmedetomidine group(group D,20 cases)and midazolam group(group M,20 cases)according to the admission number.In group D,dexmedetomidine 1 μ g/kg were constant speed pumped in 10 minutes.In group M,midazolam 0.03 mg/kg were intravenous injected.Then nasal intubation were carried.Systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial blood pressure(MAP),heart rate(HR),pulse oxygen saturation(SpO2),Ramsay sedation score,rate-pressure product(RPP),tip perfusion index(TPI)were recorded and compared before anesthesia (T0),fiberoptic bronchoscope pass by later nostril(T1),to spy on epiglottis(T2),intubation succeed(T3),after intubation 1 minute(T4)and after intubation 3 minutes(T5).Airway score and postoperative visit were evaluated.Results SBP,DBP,MAP,HR,RPP in group M were significantly higher at T1-T3 than those at T0 (P<0.05),and were significantly higher than those in group D at the same time(P< 0.05).There was no significant difference in group D(P > 0.05).Ramsay sedation score and TPI at T1-T3 in group M were significantly lower than those at To(P <0.05).Ramsay sedation score and TPI at T1-T5 in group D were significantly higher than those at T0(P < 0.05),and were significantly higher than those in group M at the same time(P < 0.05).The rate of airway score 1 score and intubation satisfaction in group D were significantly higher than those in group M[100%(20/20)vs.30%(6/20),90%(18/20)vs.50%(10/20)](P< 0.05).The rate of throat ache in group D was significantly lower than that in group M[5%(1/20)vs.35%(7/20)](P <0.05).Conclusions For difficult airway patients with nasal intubation during dexmedetomidine infusion,hemodynamics is stable and sedation is satisfied.

Objective To explore the clinical features and treatment of children with acute severe viral myocarditis.Methods The clinical data of presentation,diagnosis,therapy and prognosis of children who were admitted in our hospital from Jan 2005 to Jan 2012 with acute severe viral myocarditis(severe myocarditis group) were analyzed retrospectively.Twenty-three cases of normal healthy children in the same period were selected as control group.The levels of serum cardiac troponin(CTn)-Ⅰ and N-terminal pro-brain natriuretic peptide(NT-proBNP) were detected by ELISA method,the changes of left ventricular ejection fraction and left ventricular fraction shortening were understood by color doppler echocardiography.Results The level of CTn-Ⅰin severe myocarditis group was significantly higher than that of control group,the difference was statistically significant [(18.67 ± 12.31) ng/ml vs (0.02 ±0.01) ng/ml,P <0.05].Compared with the acute phase,the level of CTn-Ⅰshowed a trend of gradual decline in 7 d [(0.55 ±0.24) ng/ml],basic close to normal in 14 d [(0.06 ±0.03) ng/ml] (P <0.05).The level of NT-proBNP increased significantly in severe myocarditis group compared with control group [(3 067.26 ± 902.79) pg/ml vs (80.04 ± 17.79) pg/ml,P <0.05].Compared with acute phase,the levels of NT-proBNP were closed to normal in 7 d [(648.63 ±342.37) pg/ml] and 14 d [(213.58 ± 129.51) pg/ml] (P < 0.05).The left ventricular ejection fraction [(52.63 ± 6.98) % vs (71.39 ± 2.41) %] and left ventricular fraction shortening [(32.1 ± 2.97) % vs (40.04 ± 2.31) %] in severe myocarditis group were significantly lower than those in control group (P < 0.05).Conclusion Acute severe viral myocarditis of children was characterized by rapid onset,severe illness and high mortality.Early use of adrenal cortical hormone and gamma globulin under the comprehensive treatment and application temporary pacemaker can help patients to recover from the disease.
