Objective: To examine the effect of group mental intervention on implicit and explicit aggression of violent juvenile criminals. Methods: A survey investigation and IAT test on implicit aggression were employed to evaluate the aggression of violent juvenile criminals. And the effect of ten times of group intervention on aggression of juvenile criminals was analyzed. Results: After group mental intervention, the implicit aggression was not reduced significantly, but the intervention effect on explicit aggression was significant. Physical aggression and verbal aggression of explicit aggression reduced significantly, but there was no significant difference in rage and hostility. Conclusion: Group mental intervention is an effective method for reducing explicit aggression of violent juvenile criminals.

Cultured human embryonal thymus graft was performed on 80 patients with allergic rhinitis to observe the immune function of the patients and the treatment efficiency. The thymus from the fetus of intermediate abortion was cultured for 7 to 10 days. The T cell subsets and serum antigen special IgE(sas IgE) level of the patients were determined before and after the thymus transplantation. The gross treatment efficiency is up to 92.4% among the trial patients after graft for 3 years and CD8 positive cells were increased with a significantly statistical difference (P＜0.01), and sas IgE level was much lower than before thymus transplantation (P＜0.01). It was concluded that the thymus transplantation might regulate the immune function of the patients with allergic rhinitis, including increases in the number and the function of Ts cells, and a decrease of IgE level.

Objective To study the feasibility of TCI etomidate for total intravenous anesthesia (TIVA). Methods Forty patients scheduled for abdominal operation were divided into two groups with 20 cases each. Anesthesia in group E was induced and maintained with TCI etomidate 1-2 μg/ml and remifentanil 6 ng/ml,which in group P with TCI propofol 2-4 μg/ml and remifentanil 6 ng/ml to keep BIS 40-60. The perioperative changes of plasma glucose, cortisol, aldosterone and ACTH were Observed. Recovery from anethesia was recorded as well Results Both groups had the stabilized hemodynamics and glucose concentration. The plasma cortisol and ACTH concentrations in group E were decreased at the end of operation(P<0.05), but returned to preoperative level on the next day, which were not significantly changed perioperatively in group P. The time of eye opening was longer in group E than that in group P. Conclusion Etomidate has an inhibition on the function of the adrenal cortex temporally and can be used safely togather with remifentanil for TIVA in patients without hypoadrenocorticism.

A 48-year-old female presented with a one-week history of painful and enlarged lymph nodes in the left neck.One-week systemic treatment with antibiotics resulted in no obvious improvement.Skin examination revealed palpable lymph nodes between the left lateral cervical papillae and clavicle,which appeared as a string of beads with a little mobility and obvious tenderness.The largest diameter of enlarged lymph nodes was about 2 cm.No enlarged lymph nodes were palpable in the other body sites.Histopathologically,histiocytes of various shapes,immunoblasts and plasmacytoid monocytes markedly proliferated with different degrees of karyorrhexis.Immunohistochemistry revealed that the lesions were positive for CD3,CDS,CD68,mouse macrophage inflammatory protein,and CD20.A diagnosis of histiocytic necrotizing lymphadenitis was made.

BACKGROUND: Group pre-test has confirmed that amnion endothelial cell conditioned medium can induce human umbilical cord blood mesenchymal stem cells into dopaminergic neuron-like cells. In this process, neurotrophic factors and their receptors may play an important role. OBJECTIVE: To study the function of neurotrophic factors secreted by amniotic epithelial cells in the differentiation of human umbilical cord blood mesenchymal stem cells into neurons.METHODS: P1 human umbilical cord blood mesenchymal stem cells at 2×10~8 /L were incubated and assigned to 3 group. Control group was added with HG-DMEM medium. Induction group received human amniotic epithelial cell medium. Blocking agent group underwent blocking agent K252a fluid, and the incubated was conducted at 36 ℃ for 40 minutes, and then amniotic epithelial cell medium was added. Immunofluorescence chemistry was used to determine neuron specific enolase and dopamine transporter expression in human umbilical cord blood mesenchymal stem cells. Real-time quantitative PCR was employed to detect neuron specific enolase, dopamine transporter and tyrosine hydroxylase expression in human umbilical cord blood mesenchymal stem cells. RESULTS AND CONCLUSION: Nerve growth factor and brain-derived neurotrophic factor were observed in human amniotic supernatant. P1 human umbilical cord blood mesenchymal stem cells expressed Trka and Trkb. Forty-eight hours following induction, compared with the control group, positive expression of neuron specific enolase and dopamine transporter was significantly increased in the induction and blocking agent groups (P < 0.05), especially in the induction group (P < 0.05). Neuron specific enolase, dopamine transporter and tyrosine hydroxylase mRNA levels were significantly greater in the induction and blocking agent groups compared with the control group (P < 0.01), and each gene mRNA levels were significantly greater in the induction group than in the blocking agent group (P < 0.01). Results verified that neurotrophic factor in the human amniotic epithelial cells plays important effects on differentiation of human umbilical cord blood mesenchymal stem cells into neurons. The promotion effects are mediated by activating Trk receptor.

Objective To study the function of hypoxia mimics of different exposure time of deferasirox in improving the growth of micrangium in a narrow pedicle flap.Methods Fourty male SD rats were divided into 2 groups:experimental group was fed with deferasirox 100 mg/kg per day from 1d,3d,5d and 7d,respectively,before the surgery of transferring the narrow pedicle flap,while control group just fed with saline.After 7 days,the immunohistochemistry,Western blot and quantitative reverse transcription-PCR (qPCR) were performed to examine the expression of CD34.qPCR was used to examine the expression of HIF-1α,VEGF in order to investigate the regulatory effect of deferasirox in improving the growth of micrangium and the distinction among the different exposed time of deferasirox in the narrow pedicle flap.Results The deferasirox group exhibited a marked improvement in flap healing time,and with the increasing administration time of deferasirox,the expression of MVD,HIF-1α and VEGF was improved in each treated group (P＜0.05).Conclusions Deferasirox can induce HIF-1α secretion and increase CD34 expression,and so deferasirox can protect endothelial cells from hypoxic and ischaemic injury.

Objective To investigate the clinical effects of bioglue compound and anatomic plate in treatment of tibial plateau fractures. Methods 28 cases of tibial plateau fractures were treated by means of open reduction and internal fixation with bioglue compound and anatomic plate. The intervals between operation and injury ranged from 5 to 10 days. The amounts of bioglue compound implanted ranged from 3 to 8 grams. Results All the patients were followed up for 6 to 22 months. All the fractures healed satisfactorily without sunken joint surface. According to Mechant criteria, the result was excellent in 13 cases, good in 11 cases, moderate in 3 cases and poor in 1 case. The total excellent and good rate was 85.3 %. Conclusion Internal fixation with bioglue compound and anatomic plate can result in good effects in treatment of tibial plateau fractures, because the bioglue compound possesses high bone inductive potentialities to repair bone defects.

Objective To investigate the effect of tea polyphenols on global cerebral ischemia reperfusion injury in rats.Method Forty-five pathogen-free male SD rats weighing 180-220 g were randomly divided into 3 groups( n =15 each):sham operation group (group S),cerebral ischemia reperfusion group (group IR) and tea polyphenols group (group TP).Global cerebral ischemia reperfusion injury was establish by four-vessel occlusion method.At 24 h of reperfusion,five rats were chosen and Evan's blue(EB) was injected iv,and then sacrificed and brain was removed for determination of EB content; another five rats were sacrificed and brain was removed for determination of water content; five rats were chosen for Morris water maze test.Result Compared with group S,EB content and water content in brain tissue were increased in groups IR and 'rP,and escape latency was prolonged,frequency of crossing the original platform was reduced in group IR ( P ＜ 0.05 ).Compared with group IR,EB content and water content in brain tissue were decreased,and escape latency was shortened,frequency of crossing the original platform was increased in group Tp ( P ＜ 0.05).Conclusion Tea polyphenols can attenuate global cerebral ischemia reperfusion injury in rats.
