目的 对CD58在胶质瘤中的表达及意义做初步研究。方法 从癌症基因组图谱(TCGA)数据库中获取胶质瘤相关样本的基因测序结果及临床信息,分析胶质母细胞瘤(GBM)组、低级别胶质瘤(LGG)组和非瘤脑组织(Non-tumor)组中CD58的表达差异及生存预后相关性,构建预后模型分析CD58表达与危险度评分关系及CD58高表达组和低表达组的总生存期差异,采用多变量Cox回归分析CD58表达对预后的影响;将40例临床样本分为三组:非瘤脑组织(Non-tumor)组,I、Ⅱ级胶质瘤为低级别胶质瘤(LGG)组,Ⅲ、Ⅳ级胶质瘤为高级别胶质瘤(HGG)组,运用免疫组织化学(免疫组化)检测三组中CD58的表达,并分析各组之间的表达差异。结果 表达差异分析显示,GBM组、LGG组和Non-tumor组的CD58表达依次降低(均P<0.05);危险度评分与CD58表达正相关,表达越高患者生存期越短(P<0.05);多变量Cox回归分析显示CD58表达水平是影响胶质瘤预后的因素,表达水平越高,死亡风险越大;免疫组化结果显示CD58阳性反应物位于细胞胞膜,HGG组阳性细胞数高于LGG组和Non-tumor组(均P<0.05),但三组的阳性例数无差别。结论 CD58在高级别胶质瘤中的表达高于低级别胶质瘤和非瘤脑组织,其表达差异与胶质瘤生存期相关,CD58高表达是胶质瘤预后的危险因素。CD58可以作为判定胶质瘤的恶性程度及预后的一项指标。国际神经病学神经外科学杂志, 2022, 49(3): 1-7.]  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=8EFC98DF278F29B91A8DFF4728A0B88A&language=2" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">10.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=407101D967B26E0E99D91CDBF241A3F5&aid=6636DF51CA98CE796A54A57640F18547&yid=0D1D160AB8016934&vid=F4B561950EE1D31A&iid=94C357A881DFC066&sid=788931E6318420A3&eid=3FC4D669D19FF0C6&referenced_num=" target="_blank">CUX-1和XRCC3在胶质瘤中的表达及其与预后的关系</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e8%b5%b5%e5%ae%97%e6%b8%85" target="_blank">赵宗清</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e8%b5%b5%e5%bf%97%e6%98%8e" target="_blank">赵志明</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e9%99%88%e6%b5%b7%e6%ac%a3" target="_blank">陈海欣</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e5%86%af%e5%b8%86" target="_blank">冯帆</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e8%a1%a1%e9%9b%aa%e6%ba%90" target="_blank">衡雪源</a> <a class="a2" href="#">《国际神经病学神经外科学杂志》</a>2020,47(5):463-468 </div> <div><b>目的</b> 探讨同源框CUT样蛋白1(CUX-1)及X射线交错互补修复基因3(XRCC3)在组织中的表达水平,及与胶质瘤患者病理指标及预后的关系。<b>方法</b> 采用免疫组织化学染色及蛋白质印迹法检测66例胶质瘤组织以及10例正常脑组织CUX-1及XRCC3的表达水平,分析它们之间的关系及其与患者临床病理指标和预后的关系。<b>结果</b> CUX-1和XRCC3表达水平随肿瘤WHO分级的升高而上调(<i>P</i><0.01),且两者的表达与胶质瘤WHO分级及增殖指标Ki67、P53mut相关(<i>P</i><0.01)。CUX-1与XRCC3之间的表达呈正相关(<i>r</i><sub>s</sub>=0.773,<i>P</i>=0.006)。Kaplan-Meier生存曲线表明CUX-1及XRCC3高表达患者生存时间缩短(<i>P</i><0.05)。<b>结论</b> CUX-1及XRCC3两者之间的表达呈正相关,并在胶质瘤中表达上调,且与不良预后相关。  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=6636DF51CA98CE796A54A57640F18547&language=2" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">11.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=5CF32BF6DF2420AE211DA8E3946DACC2&aid=A4D06FF40CF4CA5FBCE174ABE862374F&yid=A732AF04DDA03BB3&vid=01622E3E475F966C&iid=CA4FD0336C81A37A&sid=16D8618C6164A3ED&eid=94E7F66E6C42FA23&referenced_num=" target="_blank">The effect of age of onset of PD on risk of dementia</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Aarsland+D" target="_blank">Aarsland D</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Kval%c3%b8y+JT" target="_blank">Kvaløy JT</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Andersen+K" target="_blank">Andersen K</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Larsen+JP" target="_blank">Larsen JP</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Tang+MX" target="_blank">Tang MX</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Lolk+A" target="_blank">Lolk A</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Kragh-S%c3%b8rensen+P" target="_blank">Kragh-Sørensen P</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Marder+K" target="_blank">Marder K</a> <a class="a2" href="#">《Journal of neurology》</a>2007,254(1):38-45 </div> <div>Background Dementia occurs in the majority of patients with Parkinson’s disease (PD). Late onset of PD has been reported to be associated with a higher risk for dementia. However, age at onset (AAO) and age at baseline assessment are often correlated. The aim of this study was to explore whether AAO of PD symptoms is a risk factor for dementia independent of the general effect of age. Methods Two community-based studies of PD in New York (n = 281) and Rogaland county, Norway (n = 227) and two population-based groups of healthy elderly from New York (n = 180) and Odense, Denmark (n = 2414) were followed prospectively for 3–4 years and assessed for dementia according to DSM-IIIR. All PD and control cases underwent neurological examination and were followed with neurological and neuropsychological assessments. We used Cox proportional hazards regression based on three different time scales to explore the effect of AAO of PD on risk of dementia, adjusting for age at baseline and other demographic and clinical variables. Findings In both PD groups and in the pooled analyses, there was a significant effect of age at baseline assessment on the time to develop dementia, but there was no effect of AAO independent of age itself. Consistent with these results, there was no increased relative effect of age on the time to develop dementia in PD cases compared with controls. Interpretation This study shows that it is the general effect of age, rather than AAO that is associated with incident dementia in subjects with PD.

Then, the merged document was circulated for comments and edits until a consensus emerged.The first sections in this document cover technical aspects such as instrumentation, EMG hardware and software including amplifiers and filters, digital signal analysis and instrumentation settings. Other sections cover the topics such as temporary storage, trigger and delay line, averaging, electrode types, stimulation techniques for optimal and standardised EMG examinations, and the artefacts electromyographers may face and safety rules they should follow. Finally, storage of data and databases, report generators and external communication are summarized.  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=071CF69C38987CECF61DE0627318D41D&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">14.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=AF3E50B51ACFFF87C51ECAD810EF178B&aid=BD2D2FB14BF83D6ACF47975D54F9F69E&yid=9F915C6F01DE79C5&iid=CA4FD0336C81A37A&sid=D997634CFE9B6321&eid=B6DA1AC076E37400&referenced_num=" target="_blank">帕金森病运动症状进展分析</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e7%8e%8b%e6%99%93" target="_blank">王晓</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e5%88%98%e5%8d%ab%e5%9b%bd" target="_blank">刘卫国</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e5%8d%8e%e5%b9%b3" target="_blank">华平</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e4%ba%8e%e7%bf%a0%e7%8e%89" target="_blank">于翠玉</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e6%9d%a8%e5%8d%8e" target="_blank">杨华</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e8%b5%b5%e7%87%95%e7%87%95" target="_blank">赵燕燕</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e5%88%98%e4%bd%b3%e4%bd%b3" target="_blank">刘佳佳</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e6%9d%8e%e4%ba%8c%e5%87%a4" target="_blank">李二凤</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e5%ad%99%e4%b8%b0" target="_blank">孙丰</a> <a class="a2" href="#">《临床神经病学杂志》</a>2016,(1):46-48 </div> <div>目的分析帕金森病(PD)患者运动症状进展特点。方法采用PD统一评分量表(UPDRS)Ⅲ对912例PD患者进行评估。结果与病程1年的患者比较,除病程1~2年的患者外,其他病程患者的UPDRSⅢ评分、强直分、姿势或步态异常分、轴性症状总分、言语分、步态分显著升高(均P0.05),病程5~6年及14年患者的震颤分,病程5~6年、7~8年、9~13年、14年患者的运动迟缓分、姿势分显著升高(P0.05~0.01)。轴性症状进展速度高于UPDRSⅢ评分。结论 PD患者病程早期UPDRSⅢ评分进展快,震颤症状进展独立于其他症状,轴性症状评分较UPDRSⅢ更敏感地反映疾病加重趋势。  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=BD2D2FB14BF83D6ACF47975D54F9F69E&language=2" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">15.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=F8A24911D605865EFACBC71294029D63&aid=EA00CE2A862AFCBF73037277BC25CFA4&yid=4E65715CCF57055A&vid=AA76E167F386B6B3&iid=0B39A22176CE99FB&sid=1E41DF9426604740&eid=974CBB04624305A1&referenced_num=" target="_blank">Frequency of accumulation of filaments in adaxonal cytoplasm of Schwann cells of myelinated fibers of rat spinal roots</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=A.+Ohnishi" target="_blank">A.

The frequency was higher in 4- and 8-week-old (growing) rats than in 26- and 45-week old (mature) rats, and also higher in ventral than in dorsal roots in 4-, 8- and 26-week old rats. There were no clusters on certain groups of myelinated fibers according to the size of transverse axonal area, in both the ventral and dorsal roots. Therefore, this accumulation may reflect certain functions of the adaxonal cytoplasm of Schwann cell during natural growth and maturation of the axon and myelin sheath.  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=EA00CE2A862AFCBF73037277BC25CFA4&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">16.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=79F2AEB3DA86BE9F08473E735E1D02B2&aid=8BC682C8AB0DA85AF6523F4FD9710153&yid=9EAD63ADE6B277ED&vid=339D79302DF62549&iid=E158A972A605785F&sid=C2053D4E59904B8A&eid=E04FC1B5BC47587B&referenced_num=" target="_blank">Function of circle of Willis</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Zvonimir+Vrselja" target="_blank">Zvonimir Vrselja</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Hrvoje+Brkic" target="_blank">Hrvoje Brkic</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Stefan+Mrdenovic" target="_blank">Stefan Mrdenovic</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Radivoje+Radic" target="_blank">Radivoje Radic</a>  <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Goran+Curic" target="_blank">Goran Curic</a> <a class="a2" href="#">《Journal of cerebral blood flow and metabolism》</a>2014,34(4):578-584 </div> <div>Nearly 400 years ago, Thomas Willis described the arterial ring at the base of the brain (the circle of Willis, CW) and recognized it as a compensatory system in the case of arterial occlusion. This theory is still accepted. We present several arguments that <em>via negativa</em> should discard the compensatory theory. (1) Current theory is anthropocentric; it ignores other species and their analog structures. (2) Arterial pathologies are diseases of old age, appearing after gene propagation. (3) According to the current theory, evolution has foresight. (4) Its commonness among animals indicates that it is probably a convergent evolutionary structure. (5) It was observed that communicating arteries are too small for effective blood flow, and (6) missing or hypoplastic in the majority of the population. We infer that CW, under physiologic conditions, serves as a passive pressure dissipating system; without considerable blood flow, pressure is transferred from the high to low pressure end, the latter being another arterial component of CW. Pressure gradient exists because pulse wave and blood flow arrive into the skull through different cerebral arteries asynchronously, due to arterial tree asymmetry. Therefore, CW and its communicating arteries protect cerebral artery and blood–brain barrier from hemodynamic stress.  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=8BC682C8AB0DA85AF6523F4FD9710153&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">17.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=48F3B78BBE6B99C604B508E95625973A&aid=94B0FC0D8F87557BD6F1EB1E6E4F1826&yid=EA437CDB73D9759D&vid=38B194292C032A66&iid=94C357A881DFC066&sid=34D9E20AD82A0D72&eid=09AA1448D1EAF9C1&referenced_num=" target="_blank">Effects of prevention of afferentation of the development of the chick optic lobe</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=S.C.+Bondy" target="_blank">S.C.

BULL. <strong>3</strong>(5) 411–413, 1978.—The effects of unilateral extirpation of the right optic cup of the three-day incubated chick embryo upon the rate of synthesis and the stability of DNA in the non-innervated optic lobe, have been studied. This surgical procedure prevents innervation of the optic lobe contralateral to the removed eye, while the other optic lobe is normally innervated by retinal ganglion cells of the remaining eye. At the 20th day of incubation, the DNA content of the non-innervated lobe was below that of the paired lobe receiving normal innervation. This deficiency of cell number was caused by two events; death of an excess number of neurons formed early in embryogenesis and a reduced rate of glial proliferation in the later stages of incubation.  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=94B0FC0D8F87557BD6F1EB1E6E4F1826&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">18.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=0530C17F906CE5A17F61A33055B1C6E2&aid=456A19CD9D5566A9400A397C3CD3E163&yid=AA64127AB7DEB65D&vid=F9F74EC1AA08A7B9&iid=0B39A22176CE99FB&sid=0C3F9E980968AF79&eid=86C0C9A759FDA8CA&referenced_num=" target="_blank">Release of endogenous catecholamines from slices of hypothalamus of rats</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=Martha+A.+Hamlet" target="_blank">Martha A.

Catecholamines in superfusates, and in extracts of the tissue after stimulation, were isolated by column chromatography and quantitated by liquid chromatography with electrochemical detection. Norepinephrine (NE) was not consistently demonstrable in superfusate collected under basal conditions, but 40 mM K<sup>+</sup> caused the release of from 2 to 4 ng/g of tissue per min. The addition of cocaine to the superfusate caused increases in basal and evoked release of NE. Epinephrine (E) could be measured in superfusates of slices from male but not female rats and then only when cocaine was added to the superfusate. Accordingly, the concentration of E in hypothalamus was greater in male rats than in female rats. Dopamine (DA) was not consistently measurable in the spontaneous overflow from slices either in the presence or absence of cocaine. K<sup>+</sup>-evoked release of DA could be demonstrated in slices from female rats. The addition of cocaine increased the evoked release of DA from slices from both sexes. Corticosterone, added to cocaine, had no effects on the efflux of any of the catecholamines. The experiments suggest that neuronal reuptake of all catecholamines is very efficient in the hypothalamus both under basal conditions and during evoked release.  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=456A19CD9D5566A9400A397C3CD3E163&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">19.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=8C16D12399BE54B58FB79E2673AD65EE&aid=8C5B417D9BE4F4FD8E6571B082767CD2&yid=9475FABC7A03F4AB&vid=339D79302DF62549&iid=B31275AF3241DB2D&sid=F176272DD933A0BB&eid=8C267C8DC97FEEEF&referenced_num=" target="_blank">《绵阳市社会心理服务工作管理办法》解读</a>   <em><strong></strong></em>    <a href='get_pdf_url.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=8C16D12399BE54B58FB79E2673AD65EE&aid=8C5B417D9BE4F4FD8E6571B082767CD2&yid=9475FABC7A03F4AB&vid=339D79302DF62549&iid=B31275AF3241DB2D&sid=F176272DD933A0BB&eid=8C267C8DC97FEEEF&referenced_num=' target='_blank'><img src='/ch/ext_images/free.gif' valign='bottom' title='点击此处可从《四川精神卫生》网站下载免费的PDF全文' border='0'></a>   <a href='get_pdf_url.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=8C16D12399BE54B58FB79E2673AD65EE&aid=8C5B417D9BE4F4FD8E6571B082767CD2&yid=9475FABC7A03F4AB&vid=339D79302DF62549&iid=B31275AF3241DB2D&sid=F176272DD933A0BB&eid=8C267C8DC97FEEEF&referenced_num=' target='_blank'>下载免费PDF全文</a> </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e9%bb%84%e5%9b%bd%e5%b9%b3" target="_blank">黄国平</a> <a class="a2" href="#">《四川精神卫生》</a>2021,34(6):489-493 </div> <div>2018年,国家卫生健康委员会等10部委联合发布《关于印发全国社会心理服务体系建设试点工作方案的通知》,四川省绵阳市被列为全国第一批试点地区。绵阳市人民政府依据《中华人民共和国精神卫生法》等相关法律法规和文件精神,结合前期调查研究和社会心理服务工作的试点实际,编制出台了《绵阳市社会心理服务工作管理办法》,并于2021年12月25日起施行。本文围绕社会心理服务的相关概念、办法总则、重点内容、保障措施等方面进行解读,以期为社会心理服务工作的规范、持续和有效开展提供参考。  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=8C5B417D9BE4F4FD8E6571B082767CD2&language=2" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">20.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&jid=AD25863A297CB80CBD237C75C4F3046A&aid=32CBF703154D22EF&yid=37904DC365DD7266&vid=7801E6FC5AE9020C&iid=B31275AF3241DB2D&sid=5DCBAAB000A70168&eid=3E3EF0DB5E6F2DA9&referenced_num=总被引:6,自引:1,他引:5" target="_blank">阿立哌唑对精神分裂症患者生活质量的影响</a>   <em><strong>总被引:6,自引:1,他引:5</strong></em>   </div> <div> <a href="search_by_author.aspx?subject=medicine_health&major=sjbxjsbx&field=author_name&encoding=utf-8&q=%e7%8e%8b%e5%88%9a%e5%b9%b3" target="_blank">王刚平</a> <a class="a2" href="#">《临床精神医学杂志》</a>2006,16(6):360-361 </div> <div>目的:比较阿立哌唑与利培酮对精神分裂症患者生活质量的影响。方法:60例精神分裂患者随机平分为两组各30例,分别给予阿立哌唑和利培酮治疗。疗程8周。用生活质量综合评定问卷-74(GQOLI-74)、阳性与阴性症状量表(PANSS)及副反应量表(TESS)评定疗效及不良反应。结果:阿立哌唑与利培酮均能显著提高精神分裂症患者生活质量,但阿立哌唑在改善GQOLI-74总分、躯体健康及社会功能维度优于利培酮。结论:阿立哌唑治疗有利于提高精神分裂症患者生活质量。  <a href="relate_search.aspx?pcid=A9DB1C13C87CE289EA38239A9433C9DC&cid=F36852868DF483FE8E3377698C9D0C67&aid=32CBF703154D22EF&language=2" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> </div> </div> </div> </div> </td> </tr> </table> </td> </tr> </table> <table width="870" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td height="40" align="center" class="fo2"> <a href="#" onClick="this.style.behavior='url(#default#homepage)';this.setHomePage('http://yyws.alljournals.cn')">设为首页</a> <span class="STYLE1">|</span> <a href="http://www.alljournals.cn/note.aspx">免责声明</a> <span class="STYLE1">|</span> <a href="http://www.e-tiller.com"><u>关于勤云</u></a> <span class="STYLE1">|</span> <a href="javascript:window.external.addFavorite('http://yyws.alljournals.cn','期刊界 All Journals---医药、卫生')">加入收藏</a></td> </tr> <tr> <td align="center" class="fo3"> <p align="center"> Copyright<span lang="en">©<a href="http://www.e-tiller.com"><u>北京勤云科技发展有限公司</u></a>  京ICP备09084417号    </span></p> </td> </tr> </table> </div> </body> </html>
