A page 1 of 2SCE-95Signal Control ElementAPPROVEDSIGNALINGS5217300-1288:147DescriptionThe Gamewell-FCI Signal Control Elements (SCE-95) is the interface between the Fire Alarm Control Panel's (FACPs) analog circuits and building functions. The SCE-95 connects to the panel via the SLC circuit. The SCE-95provides a means to remotely locate a fully supervised cir-cuit for the operation of signaling appliances such as horns, strobes, and horn/strobes. The SCE-95 works with all 600 Series analog addressable FACPs. For annuncia-tion and feedback at the panel, Gamewell-FCI offers a Sig-nal Control Display (SCD). The SCD is only available with the IF632 and IF650 FACPs.The SCE-95 is capable of switching 24 VDC. When used as a remote signaling circuit the SCE-95 provides all the necessary supervision of the circuit and trouble reporting via the analog circuit.The Signal Control Element (SCE-95) is designed for sur-face or flush mounting and has an integral LED which annunciates upon device activation.OperationThe signal control element connects to the SLC of the Fire Alarm Control Panel (FACP) via two-wires. In its standby mode, the SCE-95 monitors its internal circuitry for status of the device itself and supervises the external control cir-cuit for faults. In the event that a fault is detected, the SCE-95 will report a trouble to the FACP .When an event is reported to the Fire Alarm Control Panel (FACP) that requires the activation of the SCE-95, the con-trol panel communicates via the analog circuit to the SCE-95 and the signaling circuit is actuated. The integral LED is also lit for annunciation at the device.ProgrammingThe SCE-95 is programed by setting a single DIP switch easily accessible on the printed circuit board. The SCE-95’s DIP switch is used to set the address of the device.Features•Compatible with the Gamewell-FCI 600 Series analog addressable FACPs.•Supervises and operates notification appliance circuit.•Supervises DC power-in.•LED annunciates activation.•Fully supervised.•Surface or flush mounting.•Field programmable.•Style four, six, or seven wiring.•Screw terminals for field wiring connections.•2.0 A output..C S -2064p h 1.w m fSCE-95GAMEWELL-FCI12 Clintonville Road, Northford, CT 06472-1610 USA • Tel: (203) 484-7161 • Fax: (203) 484-7118CS-2047 Rev.

儿童噬血细胞综合征的研究进展
儿童噬血细胞综合征的研究进展王新宝【摘要】噬血细胞综合征是一类免疫系统功能紊乱所致的疾病,其病理生理机制是免疫缺陷和免疫调节异常,导致淋巴细胞和组织细胞过度活化,产生大量炎性因子,从而引起危及生命的过度炎性反应.临床表现为高热,肝脾、淋巴结肿大,全血细胞减少,肝功能异常和凝血功能障碍,按病因可分为遗传性和继发性两大类,其临床表现复杂,起病急骤,容易误诊.【期刊名称】《医学综述》【年(卷),期】2014(020)017【总页数】3页(P3192-3194)【关键词】噬血细胞综合征;儿童;免疫【作者】王新宝【作者单位】首都医科大学附属北京友谊医院儿科,北京100059【正文语种】中文【中图分类】R559噬血细胞综合征又称噬血细胞性淋巴组织细胞增生症，临床表现为高热，肝脾、淋巴结肿大，全血细胞减少，肝功能异常和凝血功能障碍，病理学表现为组织细胞增生伴随其吞噬各种造血细胞为特征的综合征。
噬血细胞综合征按病因可分为遗传性和继发性两大类，继发性噬血细胞综合征包括感染相关性、自身免疫相关性和恶性肿瘤相关性噬血细胞综合征，其临床表现复杂，起病急骤，容易误诊，病死率高，如能早期及时诊断治疗有利于改善预后。
为提高对本病的认识，该文就噬血细胞综合征研究进展进行综述。
1 噬血细胞综合征分类及诊断标准噬血细胞综合征按病因可分为遗传性和继发性两大类[1]，遗传性与基因缺陷和免疫缺陷有关，继发性与后天感染或肿瘤等有关，遗传性噬血细胞综合征包括家族型噬血细胞综合征和免疫缺陷相关性噬血细胞综合征，继发性噬血细胞综合征包括感染相关性噬血细胞综合征、自身免疫相关性噬血细胞综合征和恶性肿瘤相关性噬血细胞综合征。
根据噬血细胞综合征-2004诊断标准[1-2]，分子生物学符合噬血细胞综合征或者以下指标8条中符合5条即可诊断为噬血细胞综合征：①发热>38.5 ℃，持续7 d 以上；②脾大(肋下≥3 cm)；③血细胞减少(累及外周血两系或三系)血红蛋白<90 g/L，血小板<100×109L-1，中性粒细胞<1×109L-1，且非骨髓造血功能减低所致；④高三酰甘油和(或)低纤维蛋白原血症禁食后>3 mmol/L或高于同年龄的3个标准差，纤维蛋白原≤1.5 g/L或低于同年龄的3个标准差；⑤在骨髓、脾脏或淋巴结中可见噬血细胞；⑥自然杀伤细胞活性降低；⑦血清铁蛋白(>500 mg/L)和乳酸脱氢酶增高；⑧可溶性白细胞介素2受体(sCD25)增高(≥2500 U/mL)。

Temperature offset tuning: Enter parameterin “regulation mode” and tune the parameter to the displayed temperature value.3. How does it work:a. Tuning analog output: For example, if you would like to have accurate 4 ~ 20mA of output, youmaking the meter point to 20mA.b. Tuning temperature offset: This allows the displayed temperature to plus or minus 1 offset value.12Error Message13 How to Install1 Remove all the terminal blocks on the panel.2 Uncover the panel and insert SCD-LED to the “operation interface” slot.3 Cover up the panel.4 Insert the terminal blocks back to theirpositions.。

终末期糖尿病肾衰竭患者的血液透析方式的析因对比研究
终末期糖尿病肾衰竭患者的血液透析方式的析因对比研究刘萍;许家岭;胡小红;吴永贵【摘要】Objective To compare the effects of different dialysis flux and speed of the hemodialysis on dialysis.Methods Factorial design was applied concerning dialysis flux and speed.The factor of dialysis flux was set at high and low levels,and the factor of dialysis speed was set at HD,SCD and MSCD modes.Then the incidence of hypotension and related blood biochemical indexes were monitored. The changes of indexes were compared.Results The blood pressure (systolic pressure)was the worst at HD mode.The six blood bio-chemical indexes including Na were closer to normal value at high dialysis flux and low speed modes.The index of AGEs declined markedly at low speed mode,which was 60.9% compared with only 2.1% at HD mode.In addition,the occurrence of severe cardiovas-cular and cerebrovascular events was less at high dialysis flux and low speed modes.Conclusion High dialysis flux and low speed modes were optimal,which was suggested as clinical priorities.%目的：观察比较血液透析的不同通量不同速度模式，对透析效果的影响。
