Objective:To'synthesize BODIPY-FL-labeled phenylephrine(BODIPY-FL-PE)and deter-mine its biological activity.Methods:Condensation of BODIPY-FL(green fluorescence dye)and phe-nylephrine(?_1-adrenoceptor agonist)was performed by adding dicyclohexylcarbodiimide(DCC)in thepresence of absolute tetrahydrofuran(THF).The reaction occurred in absolutely oxygen and water condi-tion at room temperature.The crude product was separated and purified by thin-layer chromatography(TLC).The structure of BODIPY-FL-PE was characterized by TLC and mass spectrometry(MS).Itspharmabiological activity was determined by Western blot.Results:BODIPY-FL-PE,the target mole-cule,was synthesized and its structure was identified by using ultra-violet spectrometry(UV)and MS.The result of Western blot indicated that ?_1-adrenoceptor(?_1-AR)induced ERK phosphorylation wasconfirmed in both BODIPY-FL-PE and PE treated groups.Conclusion:The synthesized BODIPY-FL-PEhas pharmacological activity that could activate ?_1-AR.Visualization of AR behaviors could be achievedby tracing the trajectories of BODIPY-FL-PE labeled AR.It might be a promising tool for investigatingdynamic behaviors of AR in living cells.

OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.

METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.

RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.

CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

Objective To evaluate the Laparoscopic combined fiber choledochoscope common bile duct cho-lelithotomy for my own clinical experience in rencent five years.Methods Clinic data of 25 cases with choledocholi-thiasis undergoing laparoscopic common bile duct cholelithotomy from June 2010 to March 2014 were retrospectively analyzed.Results The operation was performed successfully in 24 cases,a case conversions to laparotomy,21 cases with T-tube drainage,3 cases with primary ductal submucosa closure.The operative time was 105 to 305min,mean (184.0 ±12.2 ) min, postoperative hospitalization time was 6 to 10 day, mean ( 7.7 ±0.2 ) day, a case residual stones,no bile leakage.Conclusion The beginning of Laparoscopic combined fiber choledochoscope common bile duct cholelithotomy,one-stage suture of common bile duct should be selected carefully, timely transfer laparotomy, should not aim for laparoscopic surgery success rate.

BACKGROUND: The study aimed to investigate the therapeutic benefits of intravenous Xuebijing on acute kidney injury (AKI) in rats with paraquat intoxication. METHODS: Male Sprague-Dawley rats were randomly divided equally into three groups:sham group (n=8), paraquat group (n=8) and Xuebijing-treated group (n=8) using a random number table. The rats were intraperitoneally injected with 50 mg/kg of paraquat. One hour after paraquat administration, the rats were treated intravenously with Xuebijing (8 mL/kg). At 12 hours after paraquat administration, serum was collected to evaluate kidney function, then the rats were sacrificed and kidney samples were immediately harvested. AKI scores were evaluated by renal histopathology and pro-inflammatory cytokines mRNA levels in kidney were assayed using real-time RT-PCR. RESULTS: Serum urea nitrogen, creatinine and AKI scores were significantly higher in the paraquat group, compared with the sham group (P<0.05, respectively). Moreover, interleukin (IL)-1β, IL-6 and TNF-α mRNA levels were significantly higher in the paraquat group (P<0.01, respectively). However, intravenous Xuebijing significantly decreased serum urea nitrogen, creatinine, AKI scores and IL-1β, IL-6 and TNF-α mRNA levels, compared with the paraquat group (P<0.05, respectively). CONCLUSION: Intravenous Xuebijing attenuates AKI fol owing paraquat poisoning by suppressing inflammatory response.

Objective To explore the application of diffusion weighted imaging(DWI) in diagnosis of viral encephalitis in children.Methods Conventional MR imaging(T2WI and T1WI) and DWI were performed on 20 patients with viral encephalitis diagnosed clinically.Location and number of lesions demonstrated on these imagings and percents in their abnormality were compared.Results Percen-(tage of abnormality) demonstrated on DWI was significantly higher than that on T1WI(?~2=4.44 P

Objective To study the curative effect and adverse reaction of Oxcarbazepine(OXC)on treating epilepsy in children.Me-thods One hundred and twenty-nine children with different types of epilepsy were orally given OXC,and the drug dose was added gradually.According to the seizure frequency,the cases were divided into 2 groups.Group A:more than 3 seizures occurred in 3 months prior to to take OXC;group B:more than 3 seizures occurred in 1 year prior to taking OXC.After 5 months and 1 year from beginning to take OXC,the original curative effect of the 2 groups was evaluated,respectively;on the other hand,the adverse reaction and the retention were studied.Results 1.Original effect:the rate of seizure-free was 45.8% and the total curative efficiency was 66.7% in group A(n=47);the rate of seizure-free was 92.3% in group B(n=13);in 60 partial epilepsy children,the rate of seizure-free was 56.7% and the total curative efficiency was 73.3%;Both rates were 62.2% and 75.6% of patients with OXC monotherapy and 40%,66.7% of patients were given OXC in combination with another antiepileptic drugs.2.Drug adverse reaction:24% of patients were found to have adverse reaction and most of the symptoms were light and most transient.3.Tolerability:patients' retention of OXC in 1 year was 72.2%,and in 2 years was 80.0%.Conclusions The antiepileptic effect of OXC is satisfactory and adverse reaction is light and mostly transient,OXC as a new antiepileptic drug is well tolerated as monotherapy and adjunctive therapy and should be used extensively.J Appl Clin Pediatr,2009,24(1):53-55

Objective:To evaluate the clinical efficacy of SKy bone expander system in percutaneous kyphoplasty for treat- ment of osteoporotie verterbral compression fracture.Methods:Twenty-two patients(aged 62-90 years,32 vertebrae)under- went percutaneous kyphoplasty using SKy bone expander system.The bone cement was injected into the collapsed vertebrae. The vasual analogue scale(VAS)and complications were recorded during follow up.Results:The operations were successful in all patients via unilateral or bilateral approach.The operation time ranged from 30 to 120 min.The mean volume of cement in- jected into each vertebra body was(4.8?1.1)ml,ranged from 3.1 to 6.8 ml.Extravertebral leakage of bone cement was ob- served in two vertebrae with no symptoms.All patients had their pain relieved;the VAS was 7.6?0.8 before operation,3.5?0.5 one day after operation,2.8?0.6 one week after operation,and 2.4?0.6 one month after operation,with significant difference found between preoperation and postoperation(P
