OBJECTIVE: Through the use of the categories of auditory performance (CAP-II), the speech, spatial and qualities of hearing scale-parents' version (SSQ-P), children using hearing implants quality of life (CuHI-QoL) in patients with prelingual hearing impairment to compare the rehabilitation effect between preoperative and postoperative auditory performance, speech behavior and quality of life and at the same time to figure out dose rehabilitation effect connected to age. METHOD: Mainly used classification method to compare the audotory performance, speech behavior and quality of life of 50 patients before and after 2.5 years after the implantation. At the same time these 50 patients are divided on the basis of the age received the surgery, A group received the surgery before 6(1.0-5.9) years old and group B received the therapy after this age (6.0-10.9). Their auditory performance, speech behavior and quality of life were all evaluated. RESULT: There were statistical difference between two kinds of classification method of CAP-II. In the study of SSQ-P and CuHI-QoL, there was no statistical difference in well-being and happiness before and 3 years after the implant, also there was no statistical difference in parental stress between two age groups. In addition to the above two, the rest all have statistical significance. CONCLUSION After the implant, postoperative auditory performance, speech behavior and quality of life all had improved and the smaller the age, the better the performance.

Objective To evaluate the diagnostic value of bedside video electroencephalogram (VEEG) in neonatal within 6 h after birth in diagnosing hypoxic-ischemic encephalopathy ( HIE) and the correlation of bedside VEEG results and early neural and behavioral development. Methods Neonatal severe asphyxia cases were collected and bedside VEEG and HIE were recorded and graduated. The sensitivity and specificity of different VEEG degrees within 6 h after birth were calculated in prognosing HIE degree. The sensitivity and specificity of abnormal VEEG performed within 6 h, the third day and the seventh day after birth, respectively, were compared in prognosing HIE. Neonatal behavior neurological assessment (NBNA) was performed at 7 to 14 days of age, EEG and general movements assessment (GMs), developmental screening test for child under six(DST) when patients were 3 months old, and EEG, Bayley scales of infant development(BSID) at 6 months old to analyze the correlation of bedside VEEG results and early neural and behavioral development. Results Forty-eight severe asphyxia neonatal were included, among which 12 severe asphyxia and 36 HIE, including 14 mild, 12 moderate and 10 severe HIE. There were nine normal and 39(81. 3%) abnormal VEEG including 16 mild, 11 moderate, five severe abnormal and seven inactive VEEG within 6 h after birth. There were 32(88. 9%) abnormal VEEG within 6 h after birth in 36 HIE patients. Significant positive correlation was found between VEEG within 6 h after birth and HIE (r= 0.849, P<0. 01). Severe abnormal and inactive EEG within 6 h after birth showed sensitivity of 100%, specificity of 94. 7% in predicting severe HIE. The sensitivity of VEEG testing at 6 h,3 and 7 d in predicting HIE were 88. 9%, 83. 9% and 28. 6% , correspondingly the specificity were 41.7%, 91. 7% and 100%, respectively. Nine patients with continually abnormal VEEG died in hospital. The NBNA scores of patients with moderate and severe abnormal EEG were significantly lower than those with normal EEG (both P<0. 01), the NBNA scores of patients with severe abnormal EEG were significantly lower than those with moderate abnormal EEG (P<0. 05). Thirty-five patients were followed up in the hospital at 3 months old, and 32 patients had DST >85 and three had DST between 70 and 84 with abnormal EEG. GMs assessment of one of the three patients showed absence of fidget movements, cuing a chance of cerebral palsy. Fourteen patients were followed up in hospital at 6 months old, and seven of them had abnormal EEG, four had abnormal BSID with abnormal EEG. Conclusions VEEG within 6 h after birth shows high sensitivity and specificity in prognosing HIE, and much relates to short-term neural and behavior development.

Objective To lessen the learning curve of percutaneous renal lithotripsy(PCNL),we introduced a novel ex-vivo learning and training model for PCNL under fluoroscopy and ultrasonography-guided access. Methods The model was set up nailing an adult porcine kidney with＞3 cm ureter (freshly removed from the slaughtering factory),with a full thickness flap of the thoracic wall or abdomen wall with two ribs,to a board.The porcine kidney was placed within the flap with the catheterized ureter outside.The kidney was enclosed by the flap so as to create a roodel for percutaneous renal surgery;with the ribs overlying the upper portion of the kidney.The model was fixed to the board by two nails.Artificial stone material was implanted in the renal pelvis.Fluoroscopy guidance access:Retrograde pyelography via injection of contrast medium into the ureteral catheter images the collecting system. After the long axis of the target calyx is identified,the C-arm is rotated 30 degrees toward the surgeon,placing the C-arm axis in the same posterior plane of the kidney.The needle is advanced in the plane of the fluoroscopic beam,and the appropriate needle placement is determined by obtaining a bull's-eye sign on the fluoroscope screen. Rotating the C-arm to a vertical position monitors the depth of the needle penetration. Ultrasonography guidance access:The renal pelvis can he filled with normal saline through a catheter to simulate hydronephrosis and the target calyx is identified under ultrasonography guidance.The tract dilation and stone disintegration were followed.After training,the kidney can be opened to examine the target calyx and the complication of dilation. Results Altogether,126 urologists attended a urologic endoscopic technique training course.Of the 126 trainees,104 (82.5%) successfully performed the whole percutaneous procedure.At the end of training,114 (90.5 %) of the 126 attendees rated the porcine kidney model for simulation of percutaneous renal surgery as very helpful or helpful.Conclusions This biological training model simulates realistically the clinical procedure of PCNL with respect to trainee experience in a low stress environment that provides an opportunity for repetitive performances in order to learn basic technical skills for the clinical procedure of PCNL in the future.

Objective: To investigate the effects of Fufang Jiangzhi No. 3, a compound traditional Chinese herbal medicine, on cholesterol-bile acid metabolism in rabbits with hypercholesterolemia and to explore the mechanism. Methods: Twenty-four male New Zealand white rabbits were randomly assigned into normal control group, untreated group and Fufang Jiangzhi No. 3 group, with 8 rabbits in each group. Rabbits in the untreated group and Fufang Jiangzhi No. 3 group were fed high cholesterol diet to induce hypercholesterolemia. After 4-week treatment, serum total cholesterol and bile acid contents were assessed. Activity of cholesterol 7alpha-hydroxylase (CYP7A1) in liver tissues was measured by enzyme-linked immunosorbent assay. The expressions of CYP7A1, bile salt export pump (BSEP) and small heterodimer partner (SHP) mRNAs in liver tissues were observed by real-time fluorescent quantitative polymerase chain reaction. Results: Compared with the normal control group, serum total cholesterol and bile acid contents in the untreated group were increased (P<0.01). Activity of CYP7A1 and expression of CYP7A1 mRNA were decreased and expressions of BSEP and SHP mRNAs were increased in liver tissues in the untreated group as compared with the normal control group (P<0.01). Serum total cholesterol level, and expressions of BSEP and SHP mRNAs in the Fufang Jiangzhi No. 3 group were lower than those in the untreated group (P<0.01). The CYP7A1 activity and expression of CYP7A1 mRNA in the Fufang Jiangzhi No. 3 group were increased as compared with the untreated group (P<0.01), however, there was no significant difference in bile acid between the Fufang Jiangzhi No. 3 group and the untreated group. Conclusion: Fufang Jiangzhi No. 3 can up-regulate the expression of CYP7A1 mRNA, raise the activity of CYP7A1, and inhibit the expressions of BSEP and SHP mRNAs to regulate the metabolism of total cholesterol in rabbits.

Methods: Totally 100 children diagnosed as viral upper re-spiratory tract infection were randomly divided into the observation group and the control group with 50 cases in each. The two groups of children were both given symptomatic and supportive treatment, and the observation group was given IFN-α2b (P. putida) 150 000 IU·kg-1 ·d-1 in 2-4 ml 0. 9% sodium chloride injection with aerosol inhalation, qd, 5-10 min each time, and the control group was given ribavirin 10-15 mg·kg-1 ·d-1 in 5% glucose injection 150 ml, ivd, and a course of treatment was continuous 5 d. The fever, cold symptoms ( catarrh, cough, malaise) and clinical efficiency of the two groups were compared. Results:The defervescence effect of the observation group was significantly higher than that of the control group after the treatment(P<0. 05). The effect in the children with mild and moderate cough in the observation group was better than that in the control group, and the changes were statistically sig-nificant difference(P<0. 01). The heat range, cough fading time, catarrh symptom and systemic symptom disappearance time in the observation group were significantly better than those in the control group(P<0. 05). The clinical efficient rate of the observation group was 96. 0%, which was significantly higher than that (84. 0%) in the control group(P<0. 05) . Conclusion: Combined with the conventional therapy, aerosol inhalation of IFN-α2b can be effectively and safely used for treating viral upper respiratory tract infec-tion in children, which is worthy of popularized use in clinics.

OBJECTIVETo investigate the changes of clinical and EEG features in children with febrile seizures which are prone to epilepsy four years after antiepileptic drugs valproate and/or topiramate treatment.

METHODSOne hundred and thirty-two children with febrile seizures between 2004 and 2005 and who had the indications of antiepileptic drugs treatment were administered with oral valproate and/or topiramate treatment. The children were followed up for four years. Routine blood tests, liver and renal function tests were performed twice a year. Sleeping activation EEG examination was performed once a year.

RESULTSDuring the follow-up of 1 to 10 years, 108 (98.2%) out of 110 children with valproate monotherapy were seizure-free. In the 110 cases, 95 were in the drug withdrawl and 10 were in the drug reduction. All of 13 cases receiving topiramate monotherapy were seizure-free and were in the drug withdrawl. None of the patients showed abnormalities in routine blood tests, liver and renal functions tests. Sleeping activation EEG showed normal in 102 cases, focal discharges in 8 cases, bilateral synchronized spikes in 4 cases and 3Hz spikes and polyspikes in 2 cases.

CONCLUSIONSEarly use of antiepileptic drugs valproate or topiramate is effective and safe in children with febrile seizures which are prone to epilepsy. The majority of the children have a normal sleeping activation EEG after antiepileptic drug therapy.

Objective To characterize contemporary electrographic neonatal seizures by video electroencephalogram (VEEG) and to assess the value and the limitations of two-channel (C3-C4/T3-T4) amplitude-integrated electroencephalogram (aEEG) plus original EEG signals used to diagnose neonatal seizure with video EEG as a golden standard.Methods Sixty-six neonates admitted to Children's Hospital of Fudan University from January 2011 to July 2011 with clinical or suspected clinical seizure were investigated and bedside VEEG were recorded for more than 3 hours.VEEG signals were transformed into three kinds of aEEG signals by Galileo NT PMS software:one-channel aEEG (C3-C4),one-channel aEEG (C3-C4) plus original EEG,two-channel aEEG (C3-C4/T3-T4) plus original EEG.Electrical seizure activity on VEEG was signed out with respect to its occurrence,duration and localization of seizure onset; while aEEG seizure was recorded only with its occurrence.The relationship between aEEG and VEEG was analyzed by Spearman analysis.The value and the limitations of aEEG to diagnose neonatal seizure were evaluated by sensitivity,specificity,positive predictive value and negative predictive value.Results A total of 62 traces were suitable for analysis.(1) VEEG showed 39 seizure activities,among which 8 status epilepticus; and the rest 31 neonates had 352 non-status epilepticus electrical seizures,79.3％ (279/352) of which occurred over the centrotemporal region.(2) Eight cases with status epilepticus on VEEG were all diagnosed as status epilepticus on aEEG.For non-status epilepticus electrical seizures,the sensitivity of aEEG for detection of electrical seizures was as followed:49.1％ (173/352) for one-channel aEEG,54.5 ％ (192/352) for one-channel aEEG plus original EEG,81.2％ (286/353) for two-channel aEEG plus original EEG.Results from one-channel aEEG,one-channel aEEG plus original EEG and two-channel aEEG plus original EEG were all related to VEEG (ρ =0.790,0.907 and 0.953,respectively,P＜ 0.01).(3) Sensitivity of seizure detection was 66.7％ (26/39,95％ CI:0.62-0.81) for one-channel aEEG,74.4％(29/39,95％ CI:0.78-0.96) for one-channel aEEG(C3-C4) plus original EEG and 89.7％ (35/39,95％ CI:0.89-1.00) for two-channel aEEG(C3-C4/T3-T4) plus original EEG.Conclusions VEEG might help aEEG in diagnosis of neonatal seizure.two-channel aEEG (C3-C4/T3-T4) plus original EEG could significantly increase the sensitivity of neonatal seizures indentification.

BACKGROUNDThe 12th rib is an important anatomic marker in the process of percutaneous renal surgery; while the previous models without ribs can not provide close simulation conditions to human upper abdomen. To facilitate the learning and training of percutaneous renal access and intrarenal procedures under ultrasound and fluoroscopy guidance, we reported a biological bench model for percutaneous renal surgery.

METHODSThe model was developed using an ex vivo porcine kidney with a longer than 3 cm ureter, a flap of full thickness of thoracic wall with skin, subcutaneous fascia, muscle and two ribs, as well as the standard equipment for percutaneous nephrolithotomy. The porcine kidney with a catheterized ureter was placed within the porcine flap and fixed to a wooden board with two long steel nails. Afterward, contrast medium or physiological saline (0.9% sodium chloride solution) was injected through the ureter, and the urinary system was examined with a fluoroscopy unit or an ultrasound. Artificial stone material was implanted in the renal pelvis. After practicing, the model could be dissected for kidney examination and a technical analysis.

RESULTSThe advantage of this model was simple to set up and inexpensive, by using widely available material. The biological bench model can be employed for percutanous renal access, tract dilation, nephroscopy, and stone disintegration in the training and learning of clinical practice. Imaging is feasible under fluoroscopic and ultrasound guidance. The kidney models were utilized in hands on courses with over 100 people, and 90.5% attendants rated the porcine kidney model for simulation of percutaneous renal surgery as "very helpful" or "helpful".

CONCLUSIONThis biological training model simulates realistically the clinical procedure of percutaneous nephrolithotomy under fluoroscopic and ultrasound guidance.
