Objective To summarize the characteristics of prenatal and postnatal ultrasonic image in hemivertebra fetal malformation. Methods The present study enrolled 12 ultrasound diagnosed hemivertebra fetal malformation and confirmed by either magnetic resonance imaging (MRI) or X-ray in Guangdong Provincial Maternal and Children's Hospital from January 2012 to May 2013. All the ultrasonic image were collected to summarize their characteristics. Results In the twelve cases of prenatal ultrasonic image of hemivertebrae: (1) Vertebral anomaly patterns: the irregular-shape of bones are smaller than normal vertebral bony hyperechoic which inserted into the normal intervertebral in wedge-shape, scoliosis or angular deformity. (2) Diseased parts:in the 12 fetuses, 5 had single vertebral deformity while the other 7 had multiple vertebral deformities. For the location of the lesion, there were 6 dysmorphia appeared in thoracic, 3 appearedin lumbar, 1 appeared in sacrococcygeal, 1 appeared in both cervical and thoracic, and 1 appeared in both thoracic and lumbar. (3) Associated with other malformations: 4 term delivery fetuses confirmed diagnosis of hemivertebra malformation by MRI (the diagnosis of hemivertebra was confirmed by both the fetal MRI and postnatal X-ray in 2 of them within 3 days);8 fetuses had additional anomalies, including heart malformations. Three of them were induced abortion, the X-ray images of the fetal sample showed hemivertebradysmorphia. Five women chosed induced laborin local hospital, and the X-ray images of the fetal were diagnosed as hemivertebradysmorphia. One of them with rib deletion in thoracic was missed diagnosed. Conclusions Three-dimensional ultrasonicimages can clearly show the degree of scoliosis, locate vertebra. It provides important imaging evidence for the treatment of fetal dysmorphiaafter labor.

Objective To investigate the effect of ketamine on the synaptic long-term potentiation(LTP) in the CA1 area of rat hippocampal slices,and to elucidate the mechanisms underlying the effect of ketamine on memory.Methods Hippocampal slices(400 ?m thick) were obtained from the brains of male Sprague-Dawley rats(2 months old) weighing 200-250 g that were decapitated.The slices were incubated in artificial cerebrospinal fluid(ACSF) at room temperature for at least 120 min before use.Forty-nine slices were randomly divided into 7 groups(n=7):control group,ketamine 1,5,10,30,50 and 100 ?mol?L-1 groups.All the slices in each group were perfused with ACSF,ketamine 1,5,10,30,50 or 100 ?mol?L-1,respectively.The slices in each group were performed to record evoked population spikes(PS) using extracellular microelectrode recording technique.Another forty-nine slices were randomly divided into 7 groups(n=7):LTP group,ketamine-LTP 1,5,10,30,50 and 100 ?mol?L-1 groups.All the slices in each group were perfused with ACSF,ketamine 1,5,10,30,50 or 100 ?mol?L-1,respectively.PSs were recorded for at least 30 min before LTP in each group.For LTP induction,high-frequency stimulation(HFS) conditioning pulses(100 Hz?s-1) were applied to the Schaffer collateral-commissural pathway of hippocampus using a bipolar stimulating electrode.The changes in PS amplitude after HFS were analyzed in each group.Results The PS amplitude of the rat hippocampal slices in ketamine 1,5,and 10 ?mol?L-1 groups had no significant difference compared with control group.The PS amplitude in ketamine 30,50 and 100 ?mol?L-1 groups decreased compared with control group(P

Objective To investigate celecoxib self-microemulsifying drug delivery system (CXB-SMEDDS) that was developed to increase the dissolution rate and oral bioavailability of celecoxib.Methods The formulation of CXB-SMEDDS was optimized by pseudo-ternary phase diagrams analysis.The appearance, morphology, particle size distribution and in vitro drug release behavior of CXB-SMEDDS were investigated after diluted by water.The bioavailability of CXB-SMEDDS was determined by oral administration to rats compared with CXB suspension.Results An optimized formulation was selected: Medium chain triglycerides as oil phase, Tween 20 as surfactant, Transcutol HP as cosurfactant.The ratio of oil phase, surfactant and cosurfactant was 2∶9∶9.Upon mixing with water, CXB-SMEDDS formed a clear and transparent microemulsion solution with homogeneous small spherical under transmission electron microscopy.For particle size of CXB-SMEDDS was found to be (57.6±14.2) nm.The in vitro dissolution test indicated a significant improvement in release characteristics of CXB.The AUC of CXB-SMEDDS and CXB suspension were (5.54±0.94) and (3.32±0.59) mg·L-1·h, respectively.The relative bioavailability was 166.9%.Conclusion The SMEDDS can significantly increase celecoxib dissolution in vitro and bioavailability in vivo.

Objective To investigate the expressions of CD147 and matrix metalloproteinases-9 (MMP-9)in laryngeal squamous cell carcinoma (LSCC)tissue and their clinical significance.Methods The expressions of CD147 and MMP-9 were analyzed semi-quantitatively by immunohistochemical staining in LSCC and control group tissues.Results ① The positive rate of CD147 was 83.3% (30/36)in LSCC,which was higher than that in laryngeal polyp (33.3%,5/15)and in adjacent normal tissue (16.7%,6/36);it was related to histological grade, clinical stage and lymph node metastasis status (P<0 .0 5 ).② The positive rate of MMP-9 was 7 2 .2% (2 6/3 6 )in LSCC,which was higher than that in laryngeal polyp (13.3%,2/15)and in adjacent normal tissue (5.6%,2/36);it was related to histological grade,T stage,clinical stage and lymph node metastasis status (P<0.05).③ There was a positive correlation between the expressions of CD147 and MMP-9 in LSCC tissue (r=0.721,P=0.000). Conclusion The over-expressions of CD147 and MMP-9 in LSCC may contribute to the development and metastasis of LSCC.

Objective To discuss the effects of sevoflurane on perioperative hemodynamics and serum cardiac troponin I(cTnI) in patients undergoing abdominal surgery,and offer the reference for selecting anesthetic in clinic.Methods Forty patients with ASA Ⅱ—Ⅲ,undergoing radical gastrectomy were randomly allocated into sevoflurane group(group S) and propofol group(group P),with each 20 patients.Systemic blood pressure(SBP),diastolic blood pressure(DBP),heart reat(HR) and saturation of oxygen(SPO2) were monitored as routine.The concerntration of cTnI was examined at pre-anesthesia(T1),post-induction(T2),beginning of operation(T3),end of operation(T4),the first day post-operation(T5) and the third day post-operation(T6) with radioimmunoassay.Results SBP,DBP and HR in group P at post-induction were significantly lower than those in group S(P

0.05).Significant differences were observed in analgesia grade between two groups.Visual analogue scores(VAS) in different postoperative time points(4,8,12,24 and 48h) were lower in experiment group than those in control group(P0.05).Conclusion Flurbiprofen axeti1 has preemptive analgesia effects with the chosen dosage regimen in patients undergoing thoracotomy and doesn't increase side effects.But the preemptive analgesia can't improve postoperative respiratory function.
