Objective To search for the CT and MRI morphological changes in the child patients with cerebral palsy. Method The CT scranning and MRI were carried out in 150 child patients with cerebral palsy, andthe results were analysed. Results In 150 cases, 97 cases (54.6 per cent) have abnormal findings of CT scranning. Diffuse ence-phalatrophy (42 cases), encephalomalacia focus (24 cases) porencephaly (9 cases), and localized ence-phalatrophy (7 cases) ect are the common CT morphological changes in the patients with cerebral palsy.In the 53 patients with normal findings of CT scranning, MRI was carried out for 30 cases and 25 cases(83.3 per cent) were abnormal. The delayed myelinogeny of white matter of brain is the main MRI mor-phalogical abnormality. Conclusion CT scranning and MRI have important value on the etiological diagnosis for child patientswith cerebral palsy. The combination of them can improve the diagnostic accordance rate.

ObjectiveTo investigate the effect of soluble β-amyloid protein (Aβ) oligomers on the expression levels of insulin signaling transduction cascades-associated proteins including insulin receptor ( InsR),insulin receptor substrate-Ⅰ( IRS-Ⅰ) and protein kinase B (PKB) of rat hippocampal neurons,and the pathogenesis of Alzheimer's disease (AD) in depth.MethodsSoluble Aβ oligomers (5 μl) were injected into the lateral ventriculus of the AD group by a microinjector under the stereotaxic apparatus.Normal saline solution ( NS,5 μl) was injected into the NS group in the same way,and the control group received the puncture without injection. It was repeated after 1 week and the behavior of all rats was evaluatedbyY-mazetestafter2weeks.Thenhippocampuswasremovedandunderwent immunohistochemical staining to detect the expression of proteins associated.ResultsCompared with the other groups,learning and memory ability of the Aβ-treated rats were impaired.To be specific,the times of learning were increased and the times of memory were decreased. However,there was no significant difference between the NS group and the control group.Besides,the expression levels of InsR,IRS-Ⅰ,and PKB were decreased in AD group showing that a mean optical density of staining on these proteins ( InsR:0.12 ± 0.0l ; IRS-Ⅰ:0.14 ± 0.02; PKB:0.12 ± 0.03 ) was reduced in contrast with that in the NS group and the control group.Whereas there was no significant difference between the NS group (0.40 ± 0.02,0.39 ± 0.06,0.38 ± 0.03,mean difference:- 0.13,- 0.13,- 0.17,all P ＜ 0.05 ) and the control group (0.38 ± 0.07,0.35 ± 0.03,0.35 ± 0.06,mean difference:- 0.15,- 0.07,- 0.73,all P ＜ 0.05 ).ConclusionsSoluble Aβ1-42 induced learning and memory disability of the rats.The mechanism might be that Aβ can lead to disorders of the insulin signaling transduction pathway of hippocampal neurons and decrease the expression levels of the proteins in the pathway.

Neuronal damage is associated with the excessive stimulation of N-Methyl-D- Aspartate (NMDA) receptors by glutamate during cerebral ischemia.Because of non-selective NMDA receptor antagonist can influence all NMDA receptors and produce adverse effects,and its clinical application has been restricted significantly,an increasing attention has been paid to the selective NMDA receptor in recent years.NR2B subunit antagonists are mainly divided into piperidine derivatives,amide derivatives,amidine derivatives,and aminoquinoline derivatives,etc. The representative drugs include ifenprodil and eliprodil.These drugs can selectively act on NMDA receptor NR2B subunit,and they are expected to become safe and effective neuropro- tective agents in clinical practice.

Objective To evaluate the clinical value of sentinel lymph nodes (SLN) in predicting pelvic lymph node status for early cervical squamous cell carcinoma,and approach the clinical significance of SLN detection for guiding radical abdominal trachelectomy (RAT).Outcomes of follow up and fertility were also observed.Methods A total of 31 patients with stage Ⅰ a2-Ⅰ bl squamous cell carcinoma planned to be given RAT and pelvic lymphadenectomy were enrolled.99mTe-labeled phytate was injected before surgery.Intraoperatively,SLN were identified,excised,and submitted to fast frozen section.Systematic bilateral pelvic lymphadenectomy was performed,and then RAT was performed in patients with negative SLN.All nodes were sent for routine pathological examination and immunostained with anti-cytokeratin antibody to detect micrometastases.Results SLN were detected in all patients (100％,31/31).A total of 109 SLN were identified with a mean number of 3.5 per patient.Of these,SLN of 2 patients were positive on frozen sections and proved to be metastasis by final pathologic examination and quitted the RAT.No missed micrometastasis was found using immunohistochemical staining in SLN and other lymph nodes using histologically node-negative cases.No false negative cases was found and the negative value was 100％ (31/31).The sensitivity,accuracy,and false negative rates were 100％,100％,and 0,respectively.Perioperative complications occured in 5 patients including 2 cases of bladder injury and 3 cases of uterine artery injury.No relapses occurred during follow-up.Five of 19 patients with procreative desire conceived pregnancies (4 spontaneous abortion and 1 premature birth) after surgery.Conclusions The identification of SLN using 99mTc-labeled phytate could predict the pelvic lymph node status in early stage cervical cancer.Under the guidance of SLN detection,RAT is a feasible operative modality with well prognosis and low complications for young patients who desire to preserve reproductive function.

Objective:The benefits of postoperative adjuvant therapy method for low-risk early-stage cervical squamous cell carcinoma were investigated. Methods:A total of 133 patients with low-risk early-stage cervical squamous cell carcinoma were treated at Shandong Cancer Hospital&Institute from February 2008 to March 2012. All patients received adjuvant therapy:42 were treated with pelvic ra-diotherapy (RT), 47 were treated with adjuvant chemotherapy (CT)+intracavitary radiotherapy (ICRT), and 44 were treated with concurrent chemoradiation (CCRT). Disease-free survival (DFS) and complications of the therapy were evaluated. Results:No significant differences in DFS were observed in the patients treated with RT, CT+ICRT, and CCRT (P>0.05), and the three-year DFS rates were 94.0%, 93.4%, and 97.6%, respectively. The frequencies of grade III to IV acute toxicities were significantly higher in patients treated with CCRT (34.1%) than in those treated with RT (9.5%) or CT+ICRT (16.7%) (P<0.05). No statistically significant difference was observed between the RT group and the CT+ICRT group (P>0.05). Grade I to II late toxicity was significantly more frequent in the CCRT (25%) and RT (19.0%) groups compared with the CT+ICRT group (4.3%) (P>0.05), but no statistically significant differences were observed between the CCRT and the RT groups (P>0.05). Conclusion:CT+ICRT or RT has a three-year DFS rate equivalent to CCRT but with fewer therapy com-plications for low-risk early-stage cervical squamous cell carcinoma.
