Objective To evaluate the values of amplitude-integrated electroencephalogram(aEEG) on the diagnosis of hypoxic ischemic encephalopathy(HIE),and the changes of aEEG in HIE with hypother-mia treatment.And to assess the therapeutic effect of hypothermia.Methods The changes of aEEG were continuously monitored before and after hypothermia treatment,and the proportions of various waveforms ap-pearing in aEEG were analyzed.Results A total of 90 cases were enrolled in this study,the changes of aEEG were monitored,including aEEG normal in 43 cases,mild abnormalities in 33 cases and severe abnor-malities in 14 cases.aEEG monitoring had a higher consistency with HIE grade and cranial MRI examination (Kappa ﹦0.584,P 〈0.001 ;Kappa ﹦0.590,P 〈0.001 ).The sensitivity,specificity,positive predictive val-ue,and negative predictive values of aEEG were high in predicting the severity of HIE.The index of with mild and severe abnormalities of aEEG was significant difference before and after the treatment of hypother-mia(P 〈0.05).Conclusion aEEG has a better evaluation effect on early diagnosis and severity assessing of HIE.Hypothermia can significantly reduce the proportion of abnormal aEEG after HIE,have a neuroprotective effect on the treatment of mild to moderate HIE.

Objective:The study is designed to explore the neuroimmunomodulation mediated by 5 HT 3 receptor of hippocampus in rats.Methods:ConA or lipopolysaccharide stimulated splenocytes proliferative responses are measured by TdR incorporation.Results:1 phenylbiguanide(PBG) 1 mg/kg,ip,10 ?g,icv and microinjection in the ventral hippocampus could enhance the splenocyte proliferative responses stimulated by ConA and LPS in mice and rats respectively.But the inhibitory effect on ConA stimulated response was only obtained by bilateral microinfusion of PBG in the dorsal hippocampus,while had no effect on the LPS induced proliferative responses.All of effects on mitogen stimulated splenocyte proliferation could be antiagonized by coadministration of a selective 5 HT 3 antiagonist tropisetron.Conclusion:It suggested that the 5 HT 3 receptors in the hippocampus might mediate neuro immuno modulation in which ventral and dorsal hippocampus have different effects.

BACKGROUND:Bryan cervical disc replacement and anterior cervical discectomy and fusion have a dispute in the treatment of cervical spondylosis.
OBJECTIVE:To evaluate the clinical effects of Bryan cervical disc replacement and anterior cervical discectomy and fusion by meta-analysis, thereby providing clinical evidence for treatment strategy of cervical spondylosis.
METHODS:The authors searched Medline, PubMed, EMBASE, OVID, CBM, CNKI and also searched manual y seven relevant Chinese orthopedic journals for articles pertinent to clinical research of Bryan cervical disc replacement and anterior cervical discectomy and fusion. Extracted data included the range of motion of the cervical spine, visual analog scale score, neck disability index, the Japanese Orthopaedic Association score. Meta-analysis and forest plots were conducted with RevMan4.2.2 Software.
RESULTS AND CONCLUSION:There are eight articles in the meta-analysis, including 883 patients (430 patients receiving Bryan cervical disc replacement, and 453 patients receiving anterior cervical discectomy and fusion). Meta-analysis did detect statistical y significant differences in the range of motion of the cervical spine at 3 months and 24 months postoperatively between the two groups, but did not detect statistical y significant differences in visual analog scale score, neck disability index, the Japanese Orthopaedic Association score between the two groups. These findings indicate that Bryan cervical disc replacement is superior to anterior cervical discectomy and fusion in the range of motion of the cervical spine. However, the current literature offers no evidence to support superiority of the Bryan cervical disc replacement over the anterior cervical discectomy and fusion.

RBC, plasma and hair Mn levels have been measured in 38 children with Keshan disease from the Chuxiong district of Yunan province and were compared with that of 35 healthy children. After logarithmic, transformation, normal distribution of Mn levels of RBC, plasma and hair had been presented. The geometric means of the RBC, plasma and hair Mn content of the patients were 1.22?g/g(dry basis), 0.16?g/ml and 8.76?g/g respectively. In normal subjects, the means of RBC, plasma and hair Mn were found to be 0.59?g/g (dry basis), 0.13?g/ml and 2.57?g/g. The children with Keshan disease had higher Mn levels than controls. (P

Objective: To investigate the effects of hyperbaric oxygen(HB0_2) on black pigmented bacteroides groups(BPB), obligately and facultatively anaerobes of periodontitis. Methods: 60 periodontitis cases were divided into 2 groups. The HB0_2 group(gingival scaling was done at the first visit)was exposed in 0.25 MPa pure oxygen 90 minutes each day, and treated 10 days continuously. The control group received gingival scaling at the first visit. The clinical indices of each group were measured. The microorganisms in periodontal pocket were incubated and analyzed. The number of subgingival anaerobes as well as the number of BPB,obligately and facultatively anaerobes were measured and counted by routine anaerobic culture. Results: Highly significant differences in Gingival Indices (GI), Probing Depth (PD), Attachment Loss (AL), and also significant differences in Plaque Index (PLI),and teeth mobility were seen between the HB0_2 group and the control group. There were significant difference of PLI, GI,PD,AL, teeth mobility in HB0_2 group pre-therapy and post-therapy. There were significant difference of subgingival anaerobes amounts, obligately and facultatively anaerobes sorts between pre-therapy and post-therapy. The positive rate of BPB of group HB0_2 post-therapy were reduced more than that of pre-therapy(P<0.01). Conclusion: HB0_2 has beneficial therapeutic effects on chronic and aggressive periodontitis. The mechanism of the HB0_2 therapy might inhibit the growth of subgingival obligately and facultatively anaerobes and BPB of human periodontitis, especially the obligately anaerobes and BPB in periodontal pockets.

AIM: In order to explore the mechanism of the GC - like effect of Tsiao Shaihutang (TSS), the down - regulation of glucocorticoid receptor and mRNA by TSS were studied. METHODS: GR sites were determined by receptor radio ligand binding assay method. At the same time, GR mRNA level was determined by quantitative reverse- transcriptive polymerase chain reaction (RT- PCR) method. RESULTS: (1) GR sites and GR mRNA level were down - regulated significantly after GC, TSS (P < 0.01 ) treatment . (2) GR sites and GR mRNA level in GC plus TSS group were obviously higher than those in GC group (P < 0.01 ). CONCLUSIONS: These data suggested that TSS can significantly down- regulate GR and GR mRNA level.

Objective To study seasonal variation of blood pressure (BP) in patients with essential hypertension (EH) and its association with meteorological elements. Methods In total, 1800 patients with essential hypertension were recruited by cluster sampling from three townships and towns in Qingzhou,Shandong province, 1155 men and 645 women, with an average age of 61.3 years (ranging from 29 to 85years). BP was measured for all of them in sitting position at 8:00 in the morning every seven to 14 days during July 2008 to June 2009. Local meteorological data were collected accordingly such as temperature,humidity and atmospheric pressure, and multivariate regression analysis was performed to show their association. Results In general, BP in patients with EH presented a decreasing trend during the first half year of observation, with the lowest in the summer ( May to August). From September to October, their BP began to increase gradually, and reached the peak in the winter ( November to February nest year). There was significant difference in systolic BP (SBP) and diastolic BP (DBP) between various seasons (Pspring-summer = 0.002 and 0.000, Pwinter-spring = 0.001 and 0.000, Psummer-autumn = 0.045 and 0.000,Psummer-winter =0. 000 and 0. 000, Pautumn-winter =0. 000 and 0. 000, respectively), except for those between the spring and autumn. Both SBP and DBP reversely associated with outdoor air temperature and room temperature(beta= -0.08, t = -2.39, P <0.05 and beta = -0.24, t = -6.21, P <0.01,respectively), (beta = -0.08, t = -2.39, P <0.05 and beta = -0.24, t = -6.21, P <0.01,respectively). Conclusions BP in patients with EH reveals seasonal variation, with the lowest in the summer and the highest in the winter and evident fluctuation in the spring and autumn, especially in SBP,which associates with room temperature and their blood vessel elasticity.
