Objective To evaluate the efficacy of flexible laryngeal mask airway and sevoflurane in pediatric strabismus surgery. Methods Totally 60 children undergoing elective strabismus surgery were recruited and divided into two groups with 30 cases each by random digits table:group T, in which children accepted endotracheal tube intubation and combined intravenous and inhalation anesthesia with mechanically ventilation; and group F, in which children adopted both flexible laryngeal mask airway and inhalation anesthesia of sevoflurane with spontaneous breath. Airway peak pressure (Ppeak), average airway pressure (Pmean), blood pressure (Bp) and heart rate (HR) at induction (T1), 1 min (T2), 3 min (T3) and 5 min (T4) after induction, removal of endotracheal tube or laryngeal mask airway (T5), awaking time and extubation time, occurrence of cough, dysphoria and pharyngodynia from being awake to extubation, satisfaction of patients were recorded. Results When compared to baseline, systolic pressure was lower at T, and higher at T2, T3 and T5, and HR was higher at T2-T5 in group T(P< 0.05),Bp was lower at T1-T4 in group F (P < 0.05). Bp and HR at T2-T5 in group F were lower than those in group T (P < 0.05). The awaking time was (8.1 ?2.6) min, the extubation time was (12.6 ?3.2) min, the occurrence of cough and pharyngodynia was 66.7%(20/30), 40.0%( 12/30), the dysphoria (0-1 score) was 7 cases in group T,(5.2 ± 1.1) min, (6.3 ± 1.5) rain,0,6.7%(2/30),25 cases in group F. There were significant differences between two groups (P<0.05). The satisfaction of patients in group F was higher than that in group T, there was significant difference between two groups (P< 0.05). Conclusion Flexible laryngeal mask airway with sevoflurane could offer high efficacy in pediatric strabismus surgery.

Objective To evaluate the effect of multiple-mode analgesia consists of epidural administration of lidocaine,parecoxib intravenously and patient-controlled epidural analgesia (PCEA) on patients after thoracic surgeries. Methods Total 90 patients treated with thoracic surgeries were allocated into 3 groups by random digits table,each with 30 cases. Patients accepted 1% lidocaine 5 ml epidurally 5 min before incision in group A and B,and 5 ml saline as control in group C. When chest closing parecoxib 40 mg were given in group A,and 2 ml saline as control in group B and C. All the patients were given PCEA. Postoperative hemodynamics,dosage of remifentanil and analgetics of PCEA within 48 h, visual analogue scale (VAS) of pain, rescue of pethidine, duration for first pain calling,and satisfactory scores of patients, doctors and nurses were recorded. Results Dosage of remifentanil was lower [(0.72±0.26), (0.84±1.20) μg／(kg·min)], and duration for first pain calling was longer[(35.00±2.78),(12.09±6.27) min] in group A and B than that in group C significantly[(1.80±0.84) μ,g／(kg·min) and (5.95±3.65) min](P<0.05). Analgetics of PCEA with in 48 h in group A was lower than that in group B which was lower than that in group C[(180.40±20.48), (192.54±40.15), (220.26±36.78) ml](P< 0.05). No difference was found on VAS of pain and hemodynamics among three groups when patients were kept immobilized, but VAS of pain in group A and B was lower than that in group C when patients kept moving. Satisfactory scores of patients,doctors and nurses in group A were higher. Conclusion Epidural administration of 1% lidocaine combined with intravenous paiecoxib 40 mg and PCEA an offer satisfactory postoperative analgesia for patients after elective thoracic surgeries.

AIM : To establish a HPLC method for simultaneous determination of rutin and naringenin-7-o-glucoside in Lysimachia clethroide Duby.METHODS: Using Diamonsil C_(18) (4.6 mm×250 mm,5 μm) as analytical column.The mobile phase consisted of acetonitrile (A) and 0.1% phosphoric acid ( B ) with gradient elution : 0～18rain,83%～80% B; 18～30 min,80%～86% B.The detection wavelength of rutin and naringenin-7-o-glucoside was at 254 nm and 281 nm,respectively.The flow rate was 1.0 mL/min; Column temperature was at 35 ℃.RESULTS: A better separating effect was obtained with the HPLC gradient elution method.The linear calibration curve of rutin and naringenin-7-o-glucoside were obtained in the concentration range of 1.00～48.00 μg/mL( r =0.999 3 ) and 0.64 ～ 40.72 μg/mL( r = 0.999 8 ),respectively.CONCLUSION : The HPLC method is accurate,simple and can be used to determine the contents of rutin and naringenin-7-o-glucoside in Lysimachia clethroide Duby simultaneously.

To explore the protective effect of adenovirus mediated IGF-Ⅰgene(Ad-IGF-Ⅰ)transfer on non-obese diabetic(NOD)mice. The results showed that the incidence of diabetes and degree of insulitis were significantly reduced in mice receiving Ad-IGF- Ⅰ . Treatment with Ad-IGF- Ⅰ significantly decreased apoptosis rate,expression of Fas and caspase-3, and increased expression of Bcl-xl. This study indicates the potential of IGF- Ⅰ gene therapy in protecting NOD mice from insulitis and apoptosis.

Objective To measure the parameters of mitral valve leaflets and mitral annulus in patientswithmildmitralregurgitation( MR )byreal timethree-dimensionaltransesophagealechocardiography (RT-3D-TEE),and explored the mechanism of MR.MethodsFifty-seven MR subjects were selected and twenty-eight subjects without mitral regurgitation were served as control group,all subjects were examined by RT-3D-TEE and acquired image,mitral valve quantification (MVQ) software was used for post-processing.Mitral annulus parameters (H/DAIPm,E2D,θAv-Mv,mitral annulus θnpa) and mitral valve leaflets parameters(A3DE,L2DAIPm,VA1-3tentVp1-3tentVtentHtentθnpa ) at the end of systolic were measured.The results of two groups were compared,and the most affected parameters to mild mitralregurgitation were selected.Results Compared with control group,VA3tent was decreased,mitral annulus θnpa and L2DAIPm increased,and the mitral valve leaflets θnpa was independently correlation factor of mild mitral regurgitation.ConclusionsThe mitral annulus geometry to flat in subjects with mild MR,the mitral valve local area is increased in subjects with mild MR,the mitral valve leaflets θnpa is independently correlation factor of mild mitral regurgitation.

Objective To eonstruct three eukaryotic expression vectors containing wilde-type hGHR gene and its mutants(hGHR-E42K and hGHR-H56R) related to congenital growth hormone insensitivity, then check their expression in CHO cells. Methods With the available PUC-hGHR vector, two mutate hGHR genes (hGHR-E42K and hGHR-H56R) were obtained through mutagenesis. Then three recombinants were cloned into eukaryotic expression vectors pcDNA3.1/zeo(+) with restriction enzymatic reactions.Then with Lipofectamine2000, we trans-fected expression vectors to CHO cells and screened the stably expressed CHO cells by Zeocin. RT-PCR and/or Western blotting were used to examine hGHR and STAT5-P. Results After sequencing, two mutations were introduced to hGHR, three eukaryotic expression vectors were identified. The transfected CHO cells expressed vd-hGHR or its mutants. Compared with hGH-wt, two mutate cells (E42K and H56R) had decreased phosphorylated STAT5 levels. Conclusion Three CHO cells which stably expresses wide type hGHR and its mutants were successfully established, E42K and H56R partly interfered the phosphorylation of STAT5.

BACKGROUND:Usual mechanics experiment approach cannot be applied directly to human body and the inter-comparability of models is low.Therefore finite element numerical simulation to mechanical behavior of human body has become an effective method for better understanding of the human body.OBJECTIVE:To establish a three-dimensional finite element model of femoral osteoporosis.METHODS:According to the average Chinese femur parameters,1 male patient with severe osteoporosis,aged 86 years,with no hip joint diseases,was selected.The data of femoral osteoporosis was obtained by means of spiral CT scanning.The graphical data were processed by the Mimics 11.1 (a graph processing software),and the outline curve data of femoral bone cortex inside and outside surface were obtained.The curve data were imported into the Unigraphic NX4.0 for solid modeling.The femur three-dimensional model composed of the cortical bone,cancellous bone and medullary canal was obtained.The model data were imported into the Ansys 11.0 for operations such as assigning,meshing,and contact interactions to establish three-dimensional finite element model of osteoporotic femur.RESULTS AND CONCLUSION:Three-dimensional finite element model of femur of osteoporosis was successfully established,which provides a reliable method for the construction of finite element model of femoral osteoporosis,and creates conditions for investigating femoral osteoporosis fracture fixation method and joint replacement.
