Objective To investigate the effects of ketamine on anoxia-reoxygenation(A/R)induced glutamate release from cerebral cortex neurons.Methods Primary cultured neurons obtained from cerebral cortex of fetal Wistar rats(16-18 d)were randomly divided into 3 groups:Ⅰcontrol group;ⅡA/R group andⅢketamine pretreatment+I/R group.The control group was not subjected to A/R while A/R group was exposed to anoxic air(95% N_2+5% CO_2)for 5 h followed by 24 h reoxygenation.In groupⅢdifferent doses of ketamine were added to the culture media before anoxia and the final ketamine concentrations were 1,20 and 100?mol?L~(-1) respectively.The extracellular glutamate concentration was detected at the end of 24 h reoxygenation.Results The extracellular glutamate concentration was significantly higher after 24 h reoxygenation in A/R group than in control group.Ketamine 20 and 100?mol?L~(-1) significantly inhibited glutamate release from the neurons induced by A/R in a dose-dependent manner.Conclusion Ketamine can inhibit glutamate release from neurons induced by A/R in a dose-dependent manner.

Objective To study the prevalence of thyroid diseases in systemic lupus erythematosus (SLE) patients and to analyze the prevalence of subclinical hypothyroidism (SCH) with lupus nephritis (LN).Methods A total of 813 hospitalized SLE patients were retrospectively analyzed.The demographic,clinical and biochemical data were collected.The prevalence of different thyroid diseases was calculated.Among all patients,83 patients with SCH and 562 patients without any thyroid diseases were recruited according to thyroid hormone,thyroid stimulating hormone (TSH) and anti-thyroid antibodies levels.Case control study was performed to explore the potential risk factors for SCH in SLE.T test,Mann-Whitney U test,x2 test and Logistic regression analysis were used for statistical analysis.Results Among the 813 patients,13 (1.6％) had clinical hypothyroidism,83(10.2％) had SCH,13 (1.6％) had central hypothyroidism,27(3.3％) had autoimmunethyroid disease (AITD),10 (1.2％) had hyperthyroidism,95 (11.7％) had euthyroid sick syndrome (ESS) and 11 (1.4％) had nodules.SCH was more frequent in patients with LN (13.7％,50/366) than those without LN [7.4％(33/447),x2=8.654,P＜0.01].Meanwhile,prevalence of LN was also significantly higher in SCH group in case control study [60.2％(50/83) vs 42.9％(241/562),x2=8.800,P＜0.01].Besides,SLE patients with SCH had more severe proteinuria,hypoalbuminemia,and hyperlipidemia,which were complications of LN.In addition,the SCH group presented significantly higher anti-dsDNA antibody positive rate [50.6％(42/83) vs 33.7％(212/562),x2=5.026,P＜0.01].In Logistic regression models,24-hour urine protein and serum creatinine was retained as independent correlated factors with SCH after adjusted for demographic variables,risk factors,and other potential confounders.The presence of SCH was associated with increased 24-hour urine protein levels,occurring in 10.4％ of subjects with 24-hour urine protein ≤ 150 mg,11.9％ with 24-hour urine protein 150.1-1 500 mg,17.2％ with 24-hour urine protein 1 500.1-3 500 mg,and d24.4％ with 24-hour urine protein ＞3 500 mg (P＜0.05 for trend).In addition,when eGFR ≥30 ml·min-1· 1.73 m-2,the prevalence of SCH was increased as eGFR decreased:occurring in 12.8％ with eGFR ≥90 ml·min-1· 1.73 m-2,12.6％ with eGFR 60-89.9 ml·min-1· 1.73 m-2 and 20.0％ with eGFR 30-59.9 ml ·min-1· 1.73 m-2.Conclusion Thyroid diseases are common in SLE patients,and SCH is closely related with LN and disease activity.

ObjectiveTo investigate the ideal surgical period of children with tongue-tie.MethodsThe data of 517 children with tongue-tie treated by simply clipped surgery or horizontal-to-vertical plasty were analyzed retrospectively to evaluate the effect of operation and the level of phonologic prognosis.ResultsThe sex ratio was approximately 10∶4 (male∶female) in all groups. Two cases occurred postoperative hemorrhage. The follow-up compliance was better in children <1 year old, but higher levels of noncompliance occurred in children >1 years old. One year after surgical treatment, there were no phonologic disorders caused by tongue motion in children <1 year old, but the levels of phonologic prognosis in children >1 years old were better, moderate, and insignificant respectively.ConclusionThe ideal surgical period of children with tongue-tie is age of 6～12 months.

Objective To observe the expression of STEAP4 gene(a novel obesity-related gene) during the period of human preadipocyte differentiation and to explore the relationship between the STEAP4 gene expression and adipocytes differentiation,adipogenesis.Methods Human preadipocytes were cultured and differentiated into the matured adipocytes in vitro.Adipocytes morphology and lipid accumulation were observed during this process.Total RNA was extracted from adipocytes at various time points (preadipocyte,Day 0,Day 4,Day 6,Day 8,Day 11,Day 14,and Day 17) and the level of STEAP4 mRNA expression was measured by fluorescent real-time quantitative reverse transcriptase-polyme-rase chain reaction(RT-PCR).Results The level of STEAP4 mRNA expression remained high in preadipocytes.In the presence of differentiation medium (Day 4),there was a transient upregulation in the expression of STEAP4 gene.After that,with the human preadipocytes being differentiated into matured adipocytes,the expression of STEAP4 mRNA was downregulated and reached the lowest level in fully differentiated adipocytes.There was a significant difference between any 2 detected phases in the level of STEAP4 mRNA expression (Pa

OBJECTIVETo explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology.

METHODSThe patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation.

RESULTSThe distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved.

CONCLUSIONSRapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

The influence of inner cell mass (ICM) and trophectoderm (TE) score on pregnancy outcomes in frozen-thawed blastocyst transfer cycles was analyzed. A retrospective analysis of 741 cycles of frozen-thawed blastosysts transfer was performed. All cycles were divided into four groups based on the number and morphological score of blastocysts: S-ICM B/TE B group (n=91), the single blastocyst transfer of ICM B and TE B; D-ICM B/TE B group (n=579), double blastocysts transfer of ICM B/TE B; D-ICM B/TE C group (n=35), double blastocysts transfer of ICM B/TE C; and D-ICM C/TE B group (n=36), double blastocysts transfer of TE B/ICM C. The pregnancy outcomes were compared among the four groups. As compared with D-ICM B/TE C group, the clinical pregnancy rate, implantation rate and multiple pregnancy rate were increased in D-ICM B/TE B group (74.96% vs. 57.14%, 57.43% vs. 37.14%, and 48.62% vs. 25%, respectively, P<0.05 for all). Clinical pregnancy rate and implantation rate in D-ICM B/TE B group were also higher than in D-ICM C/TE B group (74.96% vs. 50%, and 57.43% vs. 33.33%, both P<0.05). Multivariable Logistic regression analysis indicated that ICM score was a better predictive parameter for clinical pregnancy (OR=3.05, CI 1.70-5.46, P<0.001), while the trophectoderm score was a better one for early abortion (OR=0.074, CI 0.03-0.19, P<0.001). Clinical pregnancy rate and multiple pregnancy rate in S-ICM B/TE B group were significantly lower than those in D-ICM B/TE B group (46.15% vs. 74.96%, and 2.38% vs. 48.62%, both P<0.05), but there was no significant difference in the implantation rate between the two groups. It was suggested that the higher score of ICM and TE may be indicative of the better pregnancy outcomes. The ICM score is a better predictor of clinical pregnancy than TE, while TE score is a better one in predicting early abortion. Single ICM B/TE B blastocyst transfer in frozen-thawed cycles can also get satisfactory pregnancy outcomes.
