不同型号的培养基有何区别
（RPMI1640, DMEM, IMDM, MEM）
IMDM(Iscove’s Modified Dubecco’s Medium ) ⼜称为伊思柯夫改良培养液。

当初是为培养B 淋巴细胞设计的，当然也可以⽤于其它细胞。

它含有更⾼浓度的营养成分，适合于⾼密度细胞培养，如制备抗体时的杂交瘤细胞培养
含有L-⾕氨酰胺4.00mM; HEPES缓冲液25mM；不含α-硫代⽢油；不含碳酸氢钠；含酚红。

主要⽤于培养hybridoma cell lines ，macrophages，HUT78等细胞，并且这些IMDM培养的细胞同样也可以⽤RPMI-1640培养。

因为IMDM与RPMI-1640的差别也主要在于酚红和丙酮酸钠等成分的差别，⽐如，IMDM的酚红含量是RPMI-1640的3倍，并且其中含25mM HEPES和L-⾕氨酰胺。

之所以使⽤1640和DMEM是因为这两种培养基⽐较⼤众化,价格也⽐较便宜.⽽IMDM可谓为豪华版培养基,价格为前两种的1.5倍(以hyclone)为准.⼀般⽽⾔,IMDM适合⾼密度细胞培养,如细胞⼯程,造⾎⼲细胞,⾎液细胞培养.实际上,IMDM也可以⽤来培养其它细胞,如成纤维细胞,肿瘤细胞,其收获量为⼤约为1640的2-3倍左右.
DMEM 肿瘤细胞
RPMI1640 淋巴细胞
IMDM ⼈的组织细胞。

进⾏细胞杂交、基因转移实验，可选择IMDM
MEM 常⽤基础培养基。

RECSIT1.1中英文对照全文

New response evaluation criteria in solid tumours: Revised RECIST guideline (version 1.1)新版实体瘤疗效评价标准：修订的RECIST指南（1.1版本）Abstract摘要Background背景介绍Assessment of the change in tumour burden is an important feature of the clinical evaluation of cancer therapeutics: both tumour shrinkage (objective response) and disease progression are useful endpoints in clinical trials. Since RECIST was published in 2000, many investigators, cooperative groups, industry and government authorities have adopted these criteria in the assessment of treatment outcomes. However, a number of questions and issues have arisen which have led to the development of a revised RECIST guideline (version 1.1). Evidence for changes, summarised in separate papers in this special issue, has come from assessment of a large data warehouse (>6500 patients), simulation studies and literature reviews.临床上评价肿瘤治疗效果最重要的一点就是对肿瘤负荷变化的评估：瘤体皱缩（目标疗效）和病情恶化在临床试验中都是有意义的判断终点。

前列腺不典型小腺泡增生

2 A SA P与前列腺微小癌鉴别指标
ASAP与前列腺微小癌 (m inimal volume p rostatic adeno2 carcinoma,癌占活检组织总量的 5%以下 )之间的鉴别标准中 ,腺泡数目和病灶大小是最主要的一条 , ASAP腺泡的数目是癌腺泡数目的 2 /3 (11、17) , ASAP病灶比癌性病灶小一半 (014 mm、018 mm ) 。核增大、明显的核仁、核分裂象、腔内蓝色黏液及并存 P IN等形态特征在前列腺微小癌中更明显 ,但核深染及中～重度萎缩在 ASAP 比癌中更为常见 (分别为 44%、9%和 59%、35% ) 。 100%前列腺微小癌呈浸润性生长 ,但浸润性的生长方式也存在于 75%的 ASAP病例中。嗜酸性颗粒性分泌物与类晶体在两者无明显差异 [12 ] 。
前列腺癌占男性恶性肿瘤的第 2位 ,在发达国家 ,前列腺癌占全部恶性肿瘤的 19% ,在发展中国家为 513% [1 ] 。前列腺穿刺活检是发现和确诊前列腺癌的重要手段 ,但穿刺标本中经常会遇到少量不典型腺泡 ,疑似癌却又不能确定为癌 ,这便是前列腺不典型小腺泡增生 ( atyp ical small acinar p roliferation, ASAP) 。现将 ASAP形态特征、诊断标准、发病率、临床意义以及对发现前列腺癌的预测价值等作一综述。
1 A SA P的病理特征及应用现状
ASAP也称不典型腺体 ( atyp ia / atyp ical glands) [2 ] ,是由 Bostw ick等 [3 ]于 1993年首次提出的一个描述不典型腺样前列腺增生的诊断术语。4 年后这一诊断的临床意义得到首次阐述 [4 ] 。
ASAP为不典型腺泡病变 ,表现为排列紧密的灶性增生的小腺泡集落。这些小腺泡被覆一层几近透明的分泌细胞上皮 ,而基底细胞呈断片状或消失 (可经 34βE12 免疫组化证实 ) 。组织特点为 : ①有限数量的腺体 ; ② 极少腺体出现细胞不典型性 ,包括核增大、核仁增大 ; ③ 组织异型 :缺乏核异型的小腺泡杂乱无章地排列 ; ④ 腔内可见蓝色黏液、结晶体或粉红色蛋白样分泌物 [5 ] 。这些腺泡的结构形态和 /或细胞形态类似于分化较好的前列腺癌 ,但数量太少 ,只是怀疑为癌但不能明确诊断。不足以诊断为癌而做出 ASAP这一诊断主要见于两种情况 [6 ] : ①质的方面 ,缺乏足够的前列腺癌细胞和组织结构特点。例如一个病灶可能包括 12 个腺泡 ,腺泡缺乏基底细胞层 ,呈浸润性生长 ,但细胞形态和组织结构上尚未达到癌的诊断标准 (如缺少明显的核仁和明显的核增大 ) ; ②量的方面 ,包含的腺泡数量太少 ,腺泡的细胞和组织结构方面已经达到癌的诊断标准 ,但病灶的大小是其主要限制 (如 1～3个腺泡 ) 。

The owner and operator of this equipment shall have an understanding of this jack and safe operating procedures before attempting to use. The owner and operator shall be aware that use and repair of this product may require special skills and knowledge. Instructions and safety information shall be conveyed in the operator's native language before use of this jack is authorized. If any doubt exists as to the safe and proper use of this jack, remove from service immediately.Inspect before each use. Do not use if broken, bent, cracked or damaged parts are noted. Any jack that appears damaged in any way, or operates abnormally shall be removed from service immediately. If the jack has been or suspected to have been subjected to a shock load (a load dropped suddenly, unexpectedly upon it), immediately discontinue use until jack has been checked by a factory authorized service center (contact distributor or manufacturer for list of authorized service centers). It is recommended that an annual inspection be done by qualified personnel. Labels and Operator's Manuals are available from manufacturer.PRODUCT DESCRIPTIONHydraulic Transmission Jack is designed to be used as an aid in the removal and installation of automotive and light truck transmissions, transfer cases and transaxles. This telescopic style transmission jack is for use under an overhead lift or in a garage pit.NEVER use for any purpose other than those uses outlined above!PREPARATIONAssembly (refer to Figure 1)Tools required: M16 & M18 wrench.1. Four major parts should be included in the package:(a) Hydraulic unit; (b) Upright Post; (c) Saddle Assembly; (d) 2 pieces of base half with hardware.2. Attach the base halves to the upright post, then secure using threaded pins, washers and M12 nuts.3. Attach the casters onto the base halves using M12 nuts and washers.4. Place hydraulic unit on top of the upright post and secure with M10x25 bolts and washers.5. Attach saddle assembly above the ram of hydraulic unit and secure using pin and spring pin provided.6. Attach all four bracket supports onto saddle plate with bolts and wing nuts.7. Attach saddle brackets to bracket support with provided nuts.8. Finally, attach chains with bolts, washers, and nuts to saddle bracket.Before Use1. Verify that the product and application are compatible, if in doubt call Technical Service (888) 332-6419.2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with theproduct, its components and recognize the hazards associated with its use.3. With ram plunger fully retracted, remove the oil filler plug. Insert the handle into the handle sleeve, then pump 6to 8 strokes. This will help release any pressurized air, which may be trapped within the reservoir. Ensure the oil level is just below the oil filler hole. Reinstall the oil filler plug.4. To familiarize yourself with basic operation, turn the release valve lever:a. Clockwise until firm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used toraise the ram/saddle.b. Counter-clockwise, but no more than 2 turns from the closed position. This is the ‘OPEN’ release valve positionused to lower the ram/saddle.5. Ensure that jack rolls freely. Raise and lower the unloaded jack throughout the lifting range before putting intoservice to ensure the pump operates smoothly. Replace worn or damaged parts and assemblies with authorized replacement parts only.Figure 1- Transmission Jack ComponentsOPERATIONFollow the instruction for removal and installation of transmission, transfer case or transaxle according to the vehicle manufacturer's service manual.Raise saddle assembly:1. Close release valve by turning the release valve level clockwise until firm. Pump handle until saddle reaches desired height.2. Secure the load using the provided chains.Ensure center gravity of load is centered on the saddle and load is stable before moving jack. An off-centertransmission could cause the jack to tip or flip over .Be sure all tools and personnel are clear before lowering load. Slowly engage release valve!Maintain control of the rate of speed at which the load lowers at all times!Open release valve by turning lever counter-clockwise, but never more than 2 full turns. Control the rate of descent at all times. The more you open the release valve, the faster the load descends.Neveruse this jack as a work station!TROUBLESHOOTINGMAINTENANCEImportant: Use only good grade hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the potential for sudden and immediate loss of load.Adding oil1. With saddle fully lowered, set jack in its upright, level position. Remove oil filler plug.2. Fill until oil is level with the oil filler hole, reinstall oil filler plug.Changing oilFor best performance and longest life, replace the complete fluid supply at least once per year.1. With saddle fully lowered, remove oil filler plug.2. Lay the jack on its side and drain the fluid into a suitable container. Note. Dispose of hydraulic fluid in accordance with local regulations.3. Set jack in its level position. Fill until oil is level with the oil filler hole, reinstall oil filler plug.LubricationA periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that casters and pump assemblies move freely.CleaningPeriodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.Note: Never use sandpaper or abrasive material on these surfaces! StorageWhen not in use, store the jack with saddle fully lowered.SymptomPossible CausesCorrective ActionJack will not lift load• Release valve not tightly closed • Load is too heavy• Ensure release valve tightly closed • Consider higher capacity jack Jack will lift, but not maintain pressure• Release valve not tightly closed • Hydraulic unit malfunction • Ensure release valve tightly closed • Discontinue use, Contact Tech.

hemin结构式 -回复

hemin结构式-回复什么是hemin结构式？Hemin结构式是一种有机化合物的表示方法，通常用于描述某些生物分子的结构，特别是与血红素相关的分子。

血红素是一种特殊的铁血红素，与氧气结合形成氧血红素。

它在人体中起着关键的氧气传递和储存作用。

为了更好地理解hemin结构式及其与血红素的关系，我们需要深入探究其组成和形式。

首先，hemin的组成元素是碳、氢、氮和氧。

其分子式为C34H32N4O4Fe。

在这个分子中，有一个铁离子（Fe）与四个含氮的呋喃或吡嗪环（porphyrin 环）结合。

中心铁离子周围的四个席夫碱环（pyrrole环）与各自相邻的氮原子间形成一系列的共价键。

除此之外，hemin结构中还存在两个侧链，即羟基（OH）和丙酮基（CH3CO）。

其次，hemin结构式的图示方式。

为了更好地呈现hemin的结构，我们可以采用不同的表示方法。

其中，常见的一种是用Kekulé结构式。

在这种表示法中，各个原子通过线段相连，具体的原子元素和化学键类型可以用字母和线的形式标示。

对于hemin，我们可以用Kekulé结构式表示如下：H H H HN N N NH3C —C —C= —————C = C —C=OHH H H H HH H H H在这个表示式中，可以清晰地看到含氮的porphyrin环，以及连接在其周围的其他原子和化学键。

其中，氧原子（O）用一个等号（＝）表示，氮原子（N）用一个等号加一个纵线（＝）表示，碳原子（C）用一个等号、一个横线和一个纵线（＝—）表示，氢原子（H）用一个小写字母"H"表示。

最后，hemin结构式与血红素的关系。

血红素分子由一个hemin分子和一个辅助的其他分子组成。

这个辅助分子在血红素分子中的位置和形式不同于hemin结构中的侧链。

因此，虽然hemin结构式可以帮助我们了解血红素的基本结构和组成，但它并不能完全代表血红素的全貌。
