丙戊酸钠和碳青霉烯类抗菌药物相互作用的临床观察李娟;姜辉;魏金霞【摘要】目的评价丙戊酸钠和碳青霉烯类抗菌药合用相互作用的临床意义.方法收集7例症状性癫(癎)并发重症肺部感染患者应用丙戊酸钠和碳青霉烯类抗菌药治疗的临床资料,监测两药合用前、合用中及停止合用后丙戊酸血浓度.结果 4例患者合用丙戊酸钠和美罗培南期间丙戊酸血浓度明显下降,最低降至4.23 μg·mL-1,多在4~15 μg·mL-1之间,较应用美罗培南前下降40~70 μg·mL-1;1例患者同日开始应用丙戊酸钠和美罗培南,丙戊酸血浓度持续不达治疗窗;2例患者合用丙戊酸钠和亚胺培南/西司他丁期间丙戊酸血浓度无下降.结论丙戊酸钠和美罗培南合用短时间内血清丙戊酸浓度显著降低,临床上应避免二者联用;丙戊酸钠与亚胺培南/西司他丁合用未出现血清丙戊酸浓度下降,需进一步收集资料评估.%Objective To discuss the drug interaction between valproic acid (VPA) and carbapenem antibiotics (CP) in epileptic patients. Methods The clinical data of seven symptomatic epileptic patients with severe pneumonia treated with VPA and CP were analyzed retrospectively. The serum concentration of VPA was monitored before, during and after the combined use of VPA and CP. Results In four cases with combined use of VPA and meropenem, VPA was decreased significantly, with the level ranging from 4 to 15 μg o ml/-1 , which was 40-70 μg o ml/-1 lower than before the treatment. In one patient prescribed with VPA and meropenem at the same time, the serum concentration of VPA could not reach the therapeutic window. In two cases with concomitant use of VPA and imipenem, the serum level of VPA did not decrease. Conclusion Concomitant administration of VPA andmeropenem leads to a rapid decline in serum concentration of VPA. To avoid the recurrence of epileptic seizures, the concomitant administration of VPA and meropenem should be avoided in clinic. There is no decrease of serum concentration of VPA in the concomitant administration of VPA and imipenem, but more data are needed to demonstrate it.【期刊名称】《医药导报》【年(卷),期】2012(031)010【总页数】3页(P1364-1366)【关键词】丙戊酸;抗菌药,碳青霉烯类;美罗培南;亚胺培南/西司他丁;癫(癎),症状性【作者】李娟;姜辉;魏金霞【作者单位】广州军区武汉总医院干部病房一科,430070;广州军区武汉总医院干部病房一科,430070;广州军区武汉总医院干部病房一科,430070【正文语种】中文【中图分类】R971.6;R978近年来越来越多的文献报道,癫患者合用丙戊酸钠和碳青霉烯类抗菌药物时出现丙戊酸(valproic acid,VPA)血浓度急剧下降、甚至癫发作的情况。

frequency accuracy (±12.5%),which is specified in IEC60958-3.•The jitter tolerance of the DIR9001complies with IEC60958-3.•The PLL may also lock in outside of the specified sampling-frequency range,but extended range is not assured.Notice about the signal level and transmission line of the biphase input signal.•The signal level and the transmission line (optical,differential,single-ended)are different in each standard.•The biphase input signal is connected to the RXIN pin of the DIR9001.•The RXIN pin has a 5-V tolerant TTL-level input.•An optical receiver module (optical to electric converter)such as TOSLINK,which is generally used in consumer applications,is connected directly to the RXIN pin without added external components.•The output waveform of the optical receiver module varies depending on the characteristics of each product type,so a dumping resistor or buffer amplifier might be required between the optical receiver module output and the DIR9001input.Careful handling is required if the optical receiver module and the DIR9001are separated by a long distance.•The DIR9001needs an external amplifier if it is connected to a

Source,Source Selector,and Data PathThe DIR9001provides an output pulse that is synchronized with the PLL’s LOCK/UNLOCK status change.The CLKST pin outputs the PLL status change between LOCK and UNLOCK.The CLKST output pulse depends only on the status change of the PLL.This clock change/transition signal is output through CLKST.As this signal indicates a clock transition period due to a PLL status change,it can be used for muting or other appropriate functions in an application.A clock source selection caused by the CLKSEL pin does not affect the output of CLKST.CLKST does change due to PLL status change even if CKSEL =H in the XTI source mode.When DIR9001is reset in the state where it is locked to the biphase input signal,the pulse signal of CLKST is not output.That is,the priority of reset is higher than CLKST.The relation among the lock-in/unlock process,the CLKST and ERROR outputs,the output clocks (SCKO,BCKO,LRCKO),and data (DOUT)is shown in Figure 6.11Submit Documentation

PSCK[1:0].•When the PLL is in the locked condition,the PLL clock source is the clock recovered from the biphase input signal.•When PLL is in the unlocked condition,the PLL clock source is the built-in free-running clock of the VCO.•The frequency of the PLL clock source in the unlocked condition is not constant.(The VCO free-running frequency is dependent on supply voltage,temperature,and variations in the die’s wafer.)Description of XTI clock source•The XTI clock source is not used to recover the clock and decode data from the biphase input signal.•Therefore,if the DIR9001is used only for recovering the clock and decoding data from the biphase input signal,an XTI clock source is not required.In this case,the XTI pin must be connected to the DGND pin.(The DIR9001does not have a selection pin for using an XTI clock source or not using one.)The selection method of clock source•The output clock is selected from two clock sources by the level of the CKSEL pin.•The selection of the system clock source depends only on the input level of CKSEL pin.•CKSEL=L setting is required for recovering the clock and decoding data from biphase input.•CKSEL=H setting is required for XTI clock source output.•The continuity of clock during the clock source transition between the XTI source and the PLL source is not assured.Method of automatic clock source selection(CLOCK SOURCE MODE:AUTO)•This method enables selection of the clock source automatically,using the DIR9001ERROR status.The PLL source clock is output when ERROR=L;the XTI source is output when ERROR=H.•To enable automatic clock source selection,the CKSEL pin must be connected to the ERROR pin.•If XTI clock source is needed during the ERROR period,this method is recommended.•Because the clock source during ERROR status is XTI,if an XTI clock source is not provided to the XTI pin, then SCKO,BCKO,and LRCKO are not output during the ERROR period.The relationship between the clock/data source and the combination of CKSEL pin and PLL status inputs is shown in Table2.The clock tree system is shown in Figure7.13Submit Documentation FeedbackSCKO (O)BCKO (O)LRCKO (O)XTI (I)XTO (O)RXINCKSEL (I)PLL Clock

clock that is output from the built-in VCO is defined as the PLL clock source.In the locked state,the built-in PLL generates a system clock that synchronizes with the biphase input signal.In the unlocked state,the built-in PLL (VCO)generates a free-running clock.(The frequency is not constant.)The PLL can support a system clock of 128f S ,256f S ,384f S ,or 512f S ,where f S is the sampling frequency of the biphase input signal.The system clock frequency of the PLL is selected by PSCK[1:0].The DIR9001can decode a biphase input signal through its 28sampling-frequency range of kHz to 108kHz,independent of the setting of PSCK[1:0].Therefore,the DIR9001can decode a biphase input signal with a sampling frequency from 28kHz to 108kHz at all settings of PSCK[1:0]The relationship

Patton Electronics specifically disclaims all other warranties, expressed or implied, and the installation or use of this product shall be deemed an acceptance of these terms by the user.1.1 RADIO AND TV INTERFERENCEThe Model 1205RC generates and uses radio frequency energy, and if not installed and used properly—that is, in strict accordance with the manufacturer’s instructions—may cause interference to radio and television reception. The Model 1205RC has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection from such interference in a commercial installation. However, there is no guarantee that interfer-ence will not occur in a particular installation. If the Model 1205RC does cause interference to radio or television reception, which can be determined by turning the power off or removing the card, the user is encouraged to try to correct the interference by one or more of the fol-lowing measures: moving the computing equipment away from the receiver, re-orienting the receiving antenna and/or plugging the receiv-ing equipment into a different AC outlet (such that the computing equip-ment and receiver are on different branches).In the event the user detects intermittent or continuous product malfunction due to nearby high power transmitting radio frequency equipment, the user is strongly advised to take the following steps: use only data cables with an exter-nal outer shield bonded to a metal or metalized connector; and, config-ure the rear card as shown in section 3.4 of this manual.1.2 CE NOTICEThe CE symbol on your Patton Electronics equipment indicates that it is in compliance with the Electromagnetic Compatibility (EMC) directive and the Low Voltage Directive (LVD) of the Union European (EU). A Certificate of Compliance is available by contacting Technical Support.1All warranty and nonwarranty repairs must be returned freight pre-paid and insured to Patton Electronics. All returns must have a Return Materials Authorization number on the outside of the shipping contain-er. This number may be obtained from Patton Electronics Technical Support: (301) 975-1007; ; or, support@.

If any questions during installation or use of the 1205RC, contact Patton Electronics Technical Support: (301) 975-1007; ; or, ******************.2.1 FEATURES• V.35 (EIA-530) operation• Synchronous data rates from 32 to 144 Kbps• Host-to-host distances up to 300 feet• Internal or external clocking• All necessary data, clocking and control signals supported• Constant or RTS controlled carrier selections• RTS-CTS delay options of 0mS, 7mS or 53mS• Front panel LEDs show TD, DTR and CD activity for each port • Two UD-26 connectors on rear interface card• Switchable 120V or 240V power supply• Mounts in Patton’s 16-slot rack chassis and 2/4/8-slot ClusterBoxes• Made in the U.S.A.2.2 DESCRIPTIONThe Patton Model 1205RC synchronous modem eliminator rack card lets two synchronous hosts communicate with each other in the same room for a fraction of the cost of a pair of high speed modems. Supporting synchronous data rates of 32, 48, 56, 64, 72, 112, 128 and 144 Kbps, the Model 1205RC can be configured to emu-late dial-up or leased line service. Maximum distance between the connected hosts is 300 feet. Timing can be set for internal or external clock, and all necessary data, clocking and control signals are support-ed.The Model 1205RC is designed to mount in Patton’s 2U high, 16-slot rack chassis, as well as Patton’s 2/4/8-slot desktop Cluster Boxes. This rack chassis and cluster boxes feature a switchable 120/240 VAC power supply (optional 48 VDC) and hot swappable function/interface cards mounted in a mid-plane architecture. Front panel LEDs show TD, DTR and CD activity for both ports, as well as power. The rear interface card has two UD-26 connectors for patching to the host devices.3The power supply on/off switch is located on the front panel. When plugged in and switched on, a red front panel LED will glow. Since the Model 1000R16 is a “hot swappable” rack, it is not necessary for any cards to be installed before switching on the power supply.The power supply may be switched off at any time without harming the installed cards.NOTE: Please refer to the Model 1000RP Series User Manual AC and DC Rack Mount Power Supplie s for fuse and power cardreplacement information.4.2 INSTALLING THE MODEL1205RC INTO THE CHASSISThe Model 1205RC is comprised of a front card and a rear card. The two cards meet inside the rack chassis and plug into each other by way of mating 50 pin card edge connectors. Use the following steps as a guideline for installing each Model 1205RC into the rack chassis:1.Slide the rear card into the back of the chassis along themetal rails provided.2.Secure the rear card using the metal screws provided.3.Slide the card into the front of the chassis. It should meet therear card when it’s almost all the way into the chassis.4.Push the front card gently into the card-edge receptacle of therear card. It should “click” into place.5.Secure the front card using the thumb screws.NOTE:Since the Model 1000R16 chassis allows “hot swapping”of cards, it is not necessary to power down the rack when youinstall or remove a Model 1205RC.10There is no power switch on the Model 1205RC: Power is auto-matically applied to the 1205RC when its card-edge connector makes contact with the chassis’mid-plane socket, or when the chassis’power supply is turned on. Note: The 1205RC is a “hot swappable” card—it will not be damaged by plugging it in or removing it while the rack is powered up.When the Model 1205RC is powered up, and both ports are pass-ing data normally, the following LED conditions will exist:• PWR = green• TD = blinking red and green• CD = green• DTR = green13APPENDIX AMODEL1205RC SPECIFICATIONSTransmission Format: Synchronous, CCITT V.35Internal Interface:Connection to Model 1000R16 rackchassis via male card edge External Interface:UD-26 female, ports A1 and B1Data Rates:32, 48, 56, 64, 72, 112, 128 and 144 Kbps Clocking:Internal, external or receive loopback Distance:300 feet (DTE to DTE)RTS/CTS Delay:Strap selectable, 0, 7, 53 mS (+/- 15%) Indicators: Independent Bi-color LED indicators foreach port: TD, CD and DTR; common“Power” indicatorTemperature:0-50°C / 32-122°FHumidity: 5 to 95%, noncondensingDimensions: 0.95”w x 3.1”h x 5.4”l14Dear Valued Customer,Thank you for purchasing Patton Electronics products!

在过去的几十年中,锂离子电池广泛应用于小型电子设备,包括手机、笔记本电脑和摄像机[1] 。
LiCoO2层状材料作为一种有前途的商业应用材料,已得到广泛应用。
然而,钴的毒性和高成本限制了它的进一步发展[2] 。
具有层状结构的正极材料LiNi1-x-yCoxMnyO2不仅继承了其良好的LiCoO2循环性能,LiNiO2的高比电容和LiMn2O4的热稳定性,而且还具有低毒,低成本等优点[3] 。
高镍正极材料Li(Ni0.90Co0.05Mn0.05)0.998Zr0.002O2具有较高的比容量(>200mA·h/g)和良好的循环稳定性,具有很大潜力作为电动汽车使用的大容量电池的正极材料。
本文研究了烧结温度对锆掺杂改性的高镍三元材料性能的影响,便于精确掌握材料性能的影响因素及规律,确定材料合成工艺,为后续Li(Ni0.90Co0.05Mn0.05)0.998Zr0.002O2材料的工业化生产提供技术支持。
