Objective To discuss the feasibility of application of laryngeal mask airway(LMA)in pediatric corrective surgery of lingual frenum. Methods Retrospective study was conducted of 42 chil-dren using laryngeal mask airway in selective surgical correction of lingual frenum under general anesthe-sia in our hospital. The childrenˊs vital signs were recorded at five different time points:baseline before an-esthesia(T0),consciousness and eyelid reflex disappear just after anesthesia induction(T1),time right af-ter the LMA insertion(T2),3 ~ 5 min after beginning of operation(T3),and time at the extubation(T4). The success rate of first LMA insertion and the number of changing to other ventilation way were recorded. The shift of LMA and postoperative sore throat within 24h were recorded. Results The success rate of the first LMA insertion was 85. 71% . Intraoperative laryngeal mask airway leak and shift did not occur and the ventilation was also good. Vital signs of the children were stable during operation. The incidence of postop-erative sore throat was 15% within 24h. As to the heart rate,the vital signs of baseline T0 were significant-ly different from other time points(T1,T2,T3,T4). After the anesthesia,there were no significant differ-ences in heart rate among different time points(T1,T2,T3,T4). Compare with T2 and T3,the values of partial end expiratory pressure of CO2 at T0,T1,and T4 were significantly different. Compare with T0,the values of mean arterial pressure at T1,T2 and T3 were significantly different,but there was a significant difference in mean arterial pressure between T1 and T4. As to the pulse oxygen saturation,all the values were above 95% . Conclusion Laryngeal mask airway is a supraglottic airway management method. The advantages of fewer haemodynamic changes and postoperative complication are confirmed. It is feasible and safe for securing the airway in surgical correction of lingual frenum.

OBJECTIVETo establish a RP-HPLC-PDA method for determination of five triterpenic acids (pomolic acid, hawthorn acid, corosolic acid, oleanolic acid and ursolic acid) in different parts of Salvia chinensis.

METHODThe isocratic elution and separation was achieved on a Kromasil C18 column (4.6 mm x 250 mm, 5 microm), using acetonitrile-water (90:10) as the mobile phase at a flow rate of 0.8 mL x min(-1). The detection wavelength and column temperature were set at 205 nm and 28 degrees C, respectively.

RESULTThe calibration curves of pomolic acid, hawthorn acid, corosolic acid, oleanolic acid and ursolic acid were linear over the ranges of 0.096 0-2.400, 0.1230-3.075, 0.2420-6.050, 0.2830-7.075 and 0.2730-6.825 microg (r = 0.9998, 0.9997, 0.9999, 0.9995, 0.9999), respectively. The average recoveries were 98.43%, 98.13%, 100.6%, 98.19% and 99.15%%, respectively, with RSD (n=6) being 1.3%, 0.67%, 1.2%, 0.87% and 0.43%.

CONCLUSIONThe proposed method is so simple and highly reproducible that it promises to be applicable for determination of major triterpenic acids in S. chinensis.

BACKGROUND: Psychological behaviors play an important role in children accidental injury, and children with a tendency of accidental injury display specific psychological properties in characters and behaviors.OBJECTIVE: To investigate the difference of personality and behavioral characters between normal children and children with a tendency of accidental injury.DESIGN: Case controlled analysis based on suffered children and normal hildren.SETTING: Department of pediatric in a civic hospital.PARTICIPANTS: Totally 131 accidental injured children aged from 7 to 11 years were admitted at Tengzhou Civic center hospital between January and December 2001. Those with congenital intellectual disturbance and brain trauma were excluded and the rest 89 cases were asked to fill questionnaire, 8 were removed from the study due to unintegrated data and 81pieces of integral data were collected (reclaiming rate of 91.01%), including 50 males and 31 females with the mean age of (8.59±1.86) years, the intelligence quotient was(96±15) determined by Peabody picture vocabulary test(PPVT); and 81 children in control group matched in age and sex were selected from healthy children of school age without injury history and similar in some aspects, such as parents' culture degree, economic condition, educational state and the economic and culture state of inhabitancy with control group, including 45 males and 36 females with the mean age of (8.92±1.73) years, the intelligence quotient was(98±18) by PPVT. Two groups were matched in sex, age and IQ(P＞0.05).METHODS: Eysenck personality questionnaire and Achenback children behavioral rating scale(parents rating scale) were used.RESULTS: Data of two groups with 81 questionnaires in each entered into the final analysis without loss. ① Scores for psychoticisim, introverted and extroverted character and neurological quality in Esonk personality question naire were(50. 01±10.58, 55.19±12.1, 57.35±10.12) in injury group, higher than corresponding(45.63±13.81, 48.09±6.49, 50. 01±10.39)in control group( t = 2. 27-4.65, P＜0.05) . Scores for modified rating scale was(49.42±10.42) in control group, higher than(39.65±13.03)in injury group( P＜0.001); ② The median was found higher in hyperactivity, aggression, violation of discipline, bad communication, split anxiety,depression and physical complaint in boys of injury group; as well as in hyperactivity, cruelty, aggression, depression, physical complaint, social retreat, violation of law in girls of injury group, comparing to control group(P＜0.001); ③ Positive behavioral detecting rate of injury group was 32.09% (26/81), higher than 11.11% (9/81) of control group(P ＜0.001), OR was 3.78, and 95% CI was 1.66-8.59. Behavioral factors was proved of lower sensitivity(32. 1% ) with specificity of 88.9% and higher prognostic value of 74. 3%; ④ The mean score for Achenback children behavioral rating scale was(39. 84±10. 99) in boy which was obviously higher than(34.26 ± 10.43) in girls of injury group( P ＜0.05). The edian for violation of discipline and aggression in boys and depression in girls were significantly higher than the opposite sex group(P＜0.05 or 0.01) . The mean score for Achenback children behavioral rating scale was (37.62±11.03) in injury group, which were obviously higher than (17.77±12.12) of control group( P＜0.01) . ⑤Results of multiple factors Logistic analysis revealed that the risk factors for accidental injury included: aggression, hyperactivity and iolation of discipline in boys and aggression, violation of discipline and depression in girls.CONCLUSION: Children with a tendency of accidental injury has obvious ehavioral problems, behavioral factors were proved of lower sensitivity, but of igher specific positive prognostic value. Both boys and girls displayed speific characters in aggression and violation of discipline, and lack of pretendng capability comparing to normal children, thereby liable to response in on-rational manner.

Objective To explore the levels of neuron-specific enolase(NSE)in serum and cerebrospinal fluid(CSF) of children with convulsion,and its significance to the diagnosis of neuronal damage was evaluated.Methods Sixty patients were enrolled,and they were divided into 4 groups:non-nervous system disease group,peripheral nervous system disease group,brief convulsion group,and prolonged/status convulsion group.The levels of NSE in serum and CSF were detected in 4 groups,and the electroencephalography(EEG) and computed tomography/magnetic resonance imaging(CT/MRI) examinations were taken to observe the changes in patients with convulsion.Results The levels of NSE in serum and CSF of children with convulsion increased significant,especially in the prolonged/status convulsion group.Changes of NSE levels in serum and CSF were similar.Meanwhile,significant changes were found in EEG between the brief convulsion group and prolonged/status convulsion group;but no significantly changes were found in CT/MRI between the 2 groups.Conclusions NSE detection might be valuable to the diagnosis for neuronal damage in early time.The changes of NSE levels are similar to those in EEG,which are more sensitive than the changes in CT/MRI.It is very important to combine the NSE detection in serum or CSF and EEG examination in early time after convulsion for judgement to the neuronal damage and prognosis.

Objective To investigate the value of transcranial Doppler(TCD)in the prediction of the outcome and determination of brain death in patient with spontaneous intracerebral hemorrhage. Methods The waveforms and the cerebral blood flow velocities of the bilateral middle cerebral arteries(MCA)were monitored and analyzed using EME TCD in 68 comatose patients with Glasgow scores ≤7. Results The results showed that persistence of retrograde diastolic flow or small systolic forward flow in bilateral MCA lasted for more than 1 hours were observed in 28 cases of comatose patients, which was a reliable indicator for predicting or confirming brain death. Asymmetrical TCD waveforms were characteristically associated with the localized brain damage. Conclusion TCD monitoring is a useful technique for predicting outcome and guiding treatment of patient with spontaneous intracerebral hemorrhage.

Objective To investigate the features of remodeling of intramyocardial small arteries(IMSAs) in rats with idiopathic hypertension(SHR).Methods12-week-old male SHR rats(experimental group,n=10) with the age and sex matched Wistar Kyoto rats(WKY,control group,n=10) were included in present study.Experiments were continued for 18 weeks.The blood pressure of all the animals was measured at the beginning and at the end of experiment,and then all the animals were sacrificed.The left ventricle tissue sections were stained with HE,Sirius-red,elasticity fibrin and collagen fibrin double staining(P/VB) for morphological evaluation of IMSAs.The wall area(WA),luminal area(LA) and percent wall area(%WA) of IMSAs were assessed with the compute-assisted image analysis system.The vascular smooth muscle cells(VSMCs) were recognized by ?-SMA immunohistochemical staining,the proliferation and apoptosis of IMSAs were demonstrated by proliferating cell nuclear antigen(PCNA) immunohistochemical staining and TdT-mediated dUTP nick-end labeling(TUNEL) technique,respectively.The apoptosis index(AI) and proliferation index(PI) were calculated respectively.Results Systolic blood pressure(SBP) in SHR group at week 12 and week 30 were significantly higher than those in WKY group(172.00?9.78mmHg vs 123.40?5.10mmHg,200.50?14.15mmHg vs 116.30?9.38mmHg,respectively,P
