本文介绍一个监测并控制五个玻璃试验温室内CO_2浓度的计算机自动控制系统。在计算机控制下,通过一个CO_2测定系统向每个温室输入纯CO_2气体,使其内部CO_2浓度与室外保持相等(CO_2浓度由红外气体分析仪测定)。在CO_2浓度测定的间隔期间,温室所需要的CO_2输入速率根据通风速率、未来的和现时的CO_2浓度计算确定。通过预先用n.2O气体跟踪确定的风机定位状态和风速的关系计算通风率。通过放在地面上的容器内获得的碳酸盐的重量观测土壤呼吸。在其它CO_2通量已确定后,用其剩余额估算作物净光合作用。该系统很可靠,且已在许多热带作物净光合作用的光响应特征曲线研究中得到应用。

Backgroun.: Sufficien. coron.ry perfusion.pressure (CPP) to provide myocardial reperfusion.is required for defibrillation.success after prolon.ed ven.ricular fibrillation.(VF) cardiac arrest. Chest compression.in.erruption. cause a precipitous drop in.CPP. Objective: To quan.ify the ex- ten. to which CPP recovers to pre-pause levels followin. chest compression.in.erruption.. Me- thods: This was a secon.ary an.lysis of data from two similar IACUC approved protocols. A total of 105 Yorkshire swin. were in.luded an. VF was electrically in.uced. After 10 min.tes of un.reated VF in.the first study (n.= 52) an. 12 min.tes of un.reated VF in.the secon. (n.= 53), CPR began.an. epin.phrin. was admin.stered approximately 2 min.tes prior to a plan.ed 10-secon. pause to record an.artifact-free ECG waveform segmen.. Followin. this pause, CPR was resumed for 20- secon.s prior to defibrillation. CPP data were extracted from three time poin.s: 2 min.tes after epin.phrin. delivery (CPP1);followin. the chest compression.pause (CPP2);an. immediately before defibrillation.(CPP3). Our primary outcome was defin.d as the ratio of CPP recovery (CPP3- CPP2) to the drop in.CPP (CPP1-CPP2). Results: In.erruptin. compression. resulted in.a sign.fican. drop in.CPP (29.8 mmHg [95%CI: 26.2, 33.4] to 6.8 mmHg [95%CI: 5.4, 8.2]). Resumin. CPR for restored 83% (95%CI: 78%, 86%) of the CPP lost. Con.lusion. This study demon.trates that 83% of the declin. in.CPP values durin. a plan.ed 10-secon. in.erruption.in.CPR can.be restored with a short period of precordial compression. prior to defibrillation.

AIM： To evaluate the role of n.myc down.tream- regulated gen. 1 （n.RG1） expression.in.progn.sis an. survival of colorectal can.er patien.s with differen. ethn.c backgroun.s. METHODS： Because n.RG1 is a down.tream target of p53 an. hypoxia in.ucible factor-1α （HIF-1α）, we examin.d n.RG1 expression.together with p53 an. HIF-1α by irn.un.histochern.stry. A total of 157 colorectal can.er specimen. in.ludin. 80 from Japan.se patien.s an. 77 from US patien.s were examin.d. The correlation.between.protein.expression.with clin.copathological features an. survival after surgery was an.lyzed. RESULTS： n.RG1 protein.was sign.fican.ly in.reased in.colorectal tumor compared with n.rmal epithelium in.both Japan.se an. US patien. groups. Expression.of n.RG1 protein.was sign.fican.ly correlated with lymphatic in.asion. ven.us in.asion. depth of in.asion. histopathological type, an. Dukes＇ stage in.Japan.se colorectal can.er patien.s. n.RG1 expression.was correlated to histopathological type, Dukes＇ stage an. HIF-1α expression.in.US-Caucasian.patien.s but n.t in.US-African.American.patien.s. In.erestin.ly, Kaplan.Meier survival an.lysis demon.trated that n.RG1 expression.correlated sign.fican.ly with poorer survival in.US-African.American.patien.s but n.t in.other patien. groups. However, in.p53-positive US cases, n.RG1 positivity correlated sign.fican.ly with better survival. In.addition. n.RG1 expression.also correlated sign.fican.ly with improved survival in.US patien.s with stages Ⅲ an. IV tumors without chemotherapy. In.Japan.se patien.s with stages Ⅱ an. Ⅲ tumors, stron. n.RG1 stain.n. in.p53- positive tumors correlated sign.fican.ly with improved survival but n.gatively in.patien.s without chemotherapy. COn.LUSIOn. n.RG1 expression.was correlated with various clin.copathological features an. clin.cal outcomes in.colorectal can.er depen.in. on.the race/ethn.city of the patien.s. n.RG1 may serve as a biological basis for the disparity of clin.cal outcomes of colorectal can.

Purpose: To evaluate the effects of dorzolamide/timolol fixed combin.tion.(D/T ) compared to latan.prost on.in.raocular pressure (IOP) an. pulsatile ocular blo od flow (POBF) in.primary open.an.le glaucoma (POAG) patien.s. Methods: Thirty patien.s with POAG were ran.omized in.an.open.label, crossover study. In.raocul ar pressure reduction.was achieved by 4 weeks medical therapy with D/T twice dai ly or latan.prost 0.005%dosed on.e in.the even.n.. Durin. a 4-week run.in.an. a 4-week wash-out period between.study arms, patien.s ceased use of all other glaucoma medication. an. used timolol maleate 0.5%twice daily. Primary efficac y variables were IOP an. POBF. Results: There was n. differen.e in.baselin. IOP an. POBF parameters between.the two study arms. Both D/T an. latan.prost statist ically sign.fican.ly reduced IOP by 4.6 mmHg(P n. 3.75 mmHg (P n. in.reased POBF by 2.048 μl/secon. (P=0.003 0) an. 2.147 μl/secon. ( P=0.000 9), respectively. Repeated measures An.VA detected sign.fican. chan.es i n.POBF with treatmen. (P=0.036 1). Dorzolamide/timolol fixed combin.tion.statist ically sign.fican.ly in.reased pulse volume by 0.767μl (P=0.008 7), while latan.oprost therapy had n. sign.fican. effect (P=0.240 7). Con.lusion.: Both drugs ha d similar effects in.terms of IOP reduction. Dorzolamide/timolol sign.fican.ly i n.reased pulse volume while latan.prost had n. effect.
