SUMMARY Delayed postoperative spinal epidural hematoma(DPSEH) is a rare and potentially devastating complication of laminoplasty, and cervical nerve root palsy occurs more frequently than DPSEH, especially with C5 nerve root palsy. The authors describe a case of DPSEH with C5 nerve root palsy that developed in a patient 3 days after he underwent laminoplasty. In this case, a 78-year-old man with a history that having taken Aspirin without the doctor’s instruction for 5-6 years,he underwent cervical laminoplasty for mild myelopathy. On the 3rd postoperative day, he complained of weakness of his left upper extremity and could not raise his left arm. The symptom aggravated in the next few days. On the 9th postoperative day, there was an obvious motor deficit of both upper and lower extremities. Magnetic resonance imaging demonstrated abnormal signal characteristics consistent with a hematoma at levels C3-C4, compressing spinal cord. The clot was evacuated during emergency revision surgery, and the postoperative course after the operation was uneventful and the muscle strength was improved five days later. Therefore, the symptoms of DPSEH are not so typical that its possibility should be kept in mind. Sometimes a differential diagnosis should be made with C5 nerve root palsy which may only represent weakness of upper extremities. The authors recommend that magnetic resonance imaging is helpful for the diagnosis of DPSEH and a revision surgery should be taken as soon as possible once the hematoma causing the neurologic deterioration was confirmed.

OBJECTIVETo record the electrical activities of Antirior cingulate cortex (ACC) neurons by in vivo multi-channel recording methods using the model of complete freund's adjuvant (CFA) induced conditioned place avoidance (C-CPA), which has been set up in our previous studies.

METHODSThe electrode was self-made and the CPA responses were recorded by in vivo multi-channel recording method.

RESULTS(1) The electrical activities of ACC neurons could be successfully recorded by the self-made electrode. (2) Before or after the injection of CFA, rats were respectively conditioned to the different place. The firing rates of ACC neurons in the CFA-paired place vs that in the non-CFA-paired place was (0.853 ± 1.377) imp/s vs (0.221 ± 0.971) imp/s (P < 0.05, n = 26). (3) The CPA responses in the CFA-paired place vs that in the non-CFA-paired place were (303.55 ± 61.77)s vs (140.32 ± 33.52)s(P < 0.05, n = 6).

CONCLUSIONThe firing rates of rACC (rostral Anterior Cingulate Cortex) neurons were involved in the occurrence of the affective pain.

Objective To investigate the relationship between the apoptosis,expressions of Bcl-2 and Bax protein in perihematomal brain regions of rats and neurologic dysfunctions after intracerebral hemorrhage (ICH). Methods Seventy Sprague-Dawley rats were divided randomly into two groups:an experimental group and a control group.A model of ICH was established by injection of 0.5 U bacterial collagenaseⅦinto the caudate nucleus in the rats.Neurological impairment was evaluated at 6 h,12 h,24 h,48 h,72 h,7 d and 14 d after 1CH,respectively, before the rats were sacrificed.TUNEL method was used to detect apoptosis,and SP method to detect expressions of Bcl-2 and Bax protein in the perihematomal brain tissues.Results Neurological impairment occurred in all the rats after ICH,and peaked at 48 h after ICH.The apoptosis and expressions of Bcl-2 and Bax protein were peaked at 48 h,6 h and 48 h after ICH,respectively.Conclusion The degree of the neurological impairment after ICH is parallel to that of the apoptosis.Apoptosis may play an important role in neurological impairment after ICH.

Objective To investigate the association of SLC34A1 ( rs6420094 ) and RGS14 (rs4074995) polymorphisms with serum level of phosphorus in chronic hepatitis B virus (HBV) infection patients following long-term adefovir dipivoxil ( ADV ) treatment.Methods Ninety one patients with chronic HBV infections admitted in Third Hospital of Hebei Medical University during October 2012 and August 2013 were enrolled in the study.All patients received ADV treatment ( monotherapy or combination therapy) for at least two years, among whom 31 had hypophosphatemia and 60 had normal serum phosphorus levels.rs6420094 and rs4074995 were genotyped by polymerase chain reaction-restrictive fragment length polymorphism ( PCR-RFLP ) analysis.The relationship between allele frequency and serum phosphorus concentration was analyzed by Chi-Square test.Results In hypophosphatemia group, there were 13, 13, and 5 patients with genotype A/A, A/G and G/G at rs6420094, respectively;while in patients with normal serum phosphorus levels, there were 35, 24 and 1 patients with genotype A/A, A/G and G/G at rs6420094.The frequency of allele A at rs6420094 in patients with normal serum level of phosphorus was higher than that in hypophosphatemia group ( 78.3% vs.62.9%, χ2 =4.947, P <0.05 ).In hypophosphatemia group, there were 2, 11, and 18 patients with genotype A/A, A/G and G/G at rs4074995, respectively;while in patients with normal serum phosphorus level, there were 1, 21 and 38 patients with genotype A/A, A/G and G/G at rs6420094.There was no difference in the frequencies of alleles at rs4074995 between two groups (χ2 =0.625, P >0.05).Conclusion The polymorphism of rs6420094 gene may be associated with the serum level of phosphorus in patients with chronic HBV infections following long-term treatment of ADV.

Objective To assess circulating miRNAs’diagnosis value of breast cancer.Methods Conducted PubMed,Embase, the Cochrane Library,CNKI,cqvip,and wangfang database search in any language before June 2014.A total of 12 publica-tions were included in the meta-analysis.Then,the meta-analysis was performed using Meta-Disc 1.4.Meanwhile,the diag-nostic sensitivity,specitivity,positive likelyhood ratio,negative likelyhood ratio and diagnostic odds ratio were pooled by ran-dom-effects models.And the overall diagnostic performance was estimated by summary receiver operating characteristic curves (sROC)approaches.Stata12.0 was used to evaluated the publication bias.Results The pooled sensitivity was 80%(95%CI 0.77~0.82),specificity was 78% (95%CI 0.75~0.81);positive likelihood ratio was 4.09 (95%CI 2.80~5.99), negative likelihood ratio was 0.22 (95%CI 0.15~0.31),diagnostic odds rations was 20.64 (95%CI 10.24~41.62).The AUC for circulating miRNAs was 0.89 with Q value of 0.82.Publication bias was observed in existing literatures.Conclu-sion Circulating miRNAs is a potential biomarker in the diagnosis of breast cancer.

Objective To assess the diagnostic value of IMA,NLR,hs-CRP and CK-MB individually and the combined detec-tion for early acute myocardial infarction using ROC curve and Logistic regression.Methods To detect levels of IMA,NLR, hs-CRP,CK-MB and cTnI in serum or whole blood of AMI patients that had chest pain within 3 hours or between 3 and 6 hours,compared with 60 healthy people from Physical Examination Center.Applied Logistic regression,plotted ROC curve and calculated the area under ROC curve (AUC)to assess the diagnostic value of each index.Results The serum IMA,hs-CRP,CK-MB and cTnI or whole blood NLR levels of AMI patients with 3 hours were remarkably higher than normal con-trol,showing significant statistical difference (P<0.01)(AMI group:mean values of IMA,NLR,hs-CRP,CK-MB and cTnI were 96.04 U/L,3.77,13.39 mg/L,43.26 U/L and 0.063 ng/ml;normal control group:mean values of IMA,NLR,hs-CRP,CK-MB and cTnI were 78.10 U/L,2.02,3.12 mg/L,19.37 U/L and 0.040 ng/ml.The serum IMA,NLR,hs-CRP, CK-MB and cTnI levels of AMI patients in the group between 3~6 hours were higher than in the group within 3 hours (P<0.05).The AUC of combined detection of IMA,NLR,hs-CRP and CK-MB for early AMI was 0.98,higher than solo de-tection of IMA,NLR,hs-CRP and CK-MB,which were 0.89,0.83,0.79 and 0.85 respectively.Meanwhile,the AUC of com-bined detection for four markers also surpassed that of cTnI alone that was recognized as a classic serological marker to diag-nose AMI (AUC=0.78).Conclusion The combined detection of IMA,NLR,hs-CRP and CK-MB is superior to a single in-dex detection,which can significantly improve diagnostic efficiency for early AMI.
