克矽平对矽肺组织胶原基因表达的抑制作用

 使用Ｐｒｏａ＿１（Ⅰ），Ｐｒｏａ＿１（Ⅲ）人胶原ｃＤＮＡ探针，采用ｃＤＮＡ－ｍＲＮＡ斑点杂交技术，观察了染石英尘２个月、４个月矽肺大鼠及克矽平（ＰＶＮＯ）治疗１个月、３个月后肺组织中Ⅰ型和Ⅲ型前胶原ｍＲＮＡ水平的改变情况。结果表明，矽肺组织中Ⅰ、Ⅲ型前胶原ｍＲＮＡ含量比正常肺组织明显增加（Ｐ＜０．０５）；经克矽平治疗后两型胶原ｍＲＮＡ皆显著减少。我们认为矽肺病变中胶原蛋白的积聚是由石英粉尘引起胶原基因表达改变所致。药物ＰＶＮＯ能直接或间接地抑制胶原基因的转录，从而抑制矽肺病变时胶原蛋自的合成。     

伤科接骨片对Ⅰ、Ⅱ型胶原基因表达的影响

取１２０只小鼠，造成双侧桡骨中段１．５ｍｍ缺损骨折，随机分为２组。Ⅰ组为服药组，给予伤科接骨片灌服（剂量按每日０．５ｍｇ／ｇ）。Ⅱ组为未服药组。分别于术后２周及４周自骨折处取出骨痂，提取骨痂总ＲＮＡ，与Ⅰ型胶原探针片断质粒（ｐＭｃｏ１１ａ－１）及Ⅱ型胶原探针片断质粒（ｐＭｃｏ１２ａ－１）进行斑点杂交。结果发现，不论服药与否，Ⅰ型胶原ｍＲＮＡ表达水平在术后４周均明显增高，而Ⅱ型胶原ｍＲＮＡ表达水平在术后２周明显高于４周。揭示Ⅰ型胶原ｍＲＮＡ的表达表示骨化与塑形特征，Ⅱ型胶原ｍＲＮＡ的表达表示软骨修复的特征。若服药组与对照组相比，Ⅰ型胶原ｍＲＮＡ表达量，前者＞后者，分别为２７∶２０（２周），７５∶６０（４周）；Ⅱ型胶原ｍＲＮＡ表达量，前者＜后者，分别为８０∶１００（２周），８∶１５（４周）。充分说明服药组骨形成迅速，由软骨修复提早进入骨化及塑形期，以及伤科接骨片促进及增快骨修复的分子机理。     

冬虫夏草多糖脂质体抗肝纤维化的实验研究

目的探讨冬虫夏草多糖脂质体（ＣＰＬ）抗肝纤维化的作用及机制。方法动物分为肝纤维化模型组、ＣＰＬ治疗组和正常对照组,采用免疫组化和Ｎｏｒｔｈｅｒｎ杂交技术检测肝组织Ⅰ、Ⅲ型胶原蛋白及Ⅰ、Ⅲ型前胶原基因的表达。结果ＣＰＬ治疗组大鼠肝脏中Ⅰ、Ⅲ型胶原蛋白较模型对照组明显减少（Ｐ值分别＜０．０１）;ＣＰＬ治疗组大鼠肝脏组织Ⅰ、Ⅲ型前胶原ｍＲＮＡ表达量明显下降,与模型组大鼠比较差异有显著性（Ｐ值分别＜０．０５）。结论冬虫夏草多糖脂质体能明显减少肝脏的胶原沉积,并能抑制Ⅰ、Ⅲ型前胶原基因的表达。     

马钱子碱和马钱子碱氮氧化物抗血小板聚集及抗血栓形成作用的研究

观察了马钱子碱（Ｂ）和马钱子碱氮氧化物（ＢＮＯ）抗血小板聚集和血栓形成的作用，发现了Ｂ和ＢＮＯ都能显著地抑制由ＡＤＰ和胶原诱导的血小板聚集。与阿斯匹林（ＡＳＰ）比较，在同样终浓度下ＢＮＯ对ＡＤＰ诱导的血小板聚集的抑制作用与ＡＳＰ相似，但对胶原诱导的血小板聚集的抑制作用则强于ＡＳＰ。Ｂ对ＡＤＰ或胶原诱导的血小板的抑制作用均强于ＢＮＯ和ＡＳＰ。Ｂ、ＢＮＯ和ＡＳＰ抗ＡＤＰ诱导的血小板聚集的ＩＤ５０依次为０．８７７，２．３１９和２．０１２ｍｍｏｌ·ｍｌ－１；抗胶原诱导的血小板聚集的ＩＤ５０依次为０．７００，３．９５０，４．１８７ｍｍｏｌ·ｍｌ－１。Ｂ、ＢＮＯ都有类似ＡＳＰ的抗血栓形成作用，血栓抑制率分别为Ｂ：４７．５％、ＢＮＯ：５０．６％和ＡＳＰ：４２．１％。虽然Ｂ的剂量是ＢＮＯ和ＡＳＰ的一半，即有与ＢＮＯ和ＡＳＰ相近的血栓抑制率，但已显示明显的积蓄性毒性。     

消瘀片对粥样硬化兔血管壁组织ET-1mRNA和NOSmRNA表达的影响

采用原位杂交和ＲＴ－ＰＣＲ方法,观察消瘀片治疗１６周动脉粥样硬化兔后对血管壁组织ＥＴ－１ｍＲＮＡ和ＮＯＳｍＲＮＡ表达的影响。结果显示,粥样硬化组的ＥＴ－１ ｍＲＮＡ和ｉＮＯＳｍＲＮＡ表达较多,而ｃＮＯＳｍＲＮＡ表达较少。使用消瘀片后动脉 的ＥＴ－１ｍＲＮＡ表达明显减少,提示血浆和血管壁组织中的ＥＴ－１减少是由于ＥＴ－１ｍＲＮＡ转录水平降低所致。     

血管通对实验性动脉粥样硬化家兔血管壁血小板衍化生长因子A、B及c－myc基因表达的影响

本实验采用斑点印迹杂交和原位杂交技术，进一步探讨血管通对与血管平滑肌细胞（ＶＳＭＣ）增生相关基因表达的影响。结果表明，高脂组家兔血管壁血小板衍化生长因子（ＰＤＧＦ）－Ａ的ｍＲＮＡ呈高表达，杂交阳性颗粒主要分布在动脉粥样硬化（ＡＳ）斑块边缘区及新生斑块区的ＳＭＣ胞浆内，而血管通组家兔血管壁ＰＤＧＦ－ＡｍＲＮＡ表达水平明显低于高脂组；高脂组血管斑块组织ｃ－ｍｙｃ的ｍＲＮＡ表达水平亦比正常组高，血管通组血管壁ｃ－ｍｙｃｍＲＮＡ表达水平下降。上述结果初步说明血管通可能是通过影响血管壁ＰＤＧＦ－Ａ、ｃ－ｍｙｃ的ｍＲＮＡ表达水平，以抑制ＶＳＭＣ增生，阻止ＡＳ形成。     

前部缺血性视神经病变的临床检查分析

为了解前部缺血性视神经病变（ａｎｔｅｒｉｏｒｉｓｃｈｅｍｉｃｏｐｔｉｃｎｅｕｒｏｐａｔｈｙ，ＡＩＯＮ）的特点，我们自１９９３年１月～１９９８年６月，对本病５４例５６只患眼进行了临床检查，分析如下。１资料与方法ＡＩＯＮ５４例５６只患眼中男３１例３２只眼...     

伤科接骨片对I,II型胶原基因表达的影响

取１２０只小鼠，造成双侧桡骨中段１．５ｍｍ缺损骨折，随机分为２组。Ｉ组为服药组，给予伤科接骨片灌服（剂量按每日０．５ｍｇ／ｇ）。Ⅱ组为未服药组。分别于术后２周及４周自骨折处取出骨痂，提取骨痂总ＲＮＡ，与Ｉ型胶原探针片断质粒（ｐＭｃｏ１１ａ－１）及Ⅱ型胶原探针片断质粒（ｐＭｃｏ１２ａ－１）进行斑点杂交。结果发现不论服药与否，Ｉ型胶原ｍＲＮＡ表达水平在术后４周均明显增高，而Ⅱ型胶原ｍＲＮＡ表达水平在术     

补肾法对实验性骨质疏松MMP—9及Ⅰ型胶原mRNA表达的影响

为了探讨补肾法治疗绝经后骨质疏松症的分子作用环节，本研究以成年卵巢切除大鼠作为骨质疏松实验模型，通过斑点杂交技术，在ｍＲＮＡ水平分析模型组，密骨片组及假手术组骨组织基质金属蛋白酶（ＭＭＰ－９）和Ⅰ型胶原表达。通过原位杂交技术，研究两个基因ｍＲＮＡ在骨细胞的分布。结果显示，模型组大鼠ＭＭＰ－９和Ⅰ型胶原表达均较假手术组高，而密骨片治疗后，两个基因表达均下降。原位杂交显示ＭＭＰ－９ｍＲＮＡ主要在破骨细胞，骨髓单核细胞和一些骨基质表面衬细胞中表达，Ⅰ型胶原ｍＲＮＡ则定位于成骨细胞。提示ＭＭＰ－９在骨质疏松骨丢失过程中起重要作用；骨质疏松病理过程中，骨吸收和骨形成均增加，骨呈高转换状态，密骨片治疗作用主要是降低骨转换率，维持骨量，其发生是由于相关基因表达改变的结果     

脾虚患者胃粘膜前列腺素和环核苷酸改变的观察

本文观察了７５例慢性胃病患者胃粘膜三种前列腺素和环核苷酸含量，发现脾虚组患者胃粘膜ＰＧＥ＿２、６－ｋｅｔｏ－ＰＧＦ＿（１ａ）、６－ｋｅｔｏ－ＰＧＦ＿（１ａ）／Ｔ×Ｂ＿２比值及ｃＡＭＰ含量均明显低于肝气犯胃组（Ｐ＜０．０５～０．０１），ＴＸＢ＿２、ｃＧＭＰ及ｃＡＭＰ／ｃＧＭＰ比值则两组差异不显著，还发现胃粘膜ＰＧＥ＿２、６－ｋｅｔｏ－ＰＧＦ＿（１ａ）与ｃＡＭＰ呈明显的正相关。提示脾虚时胃粘膜ＰＧ＿ｓ和环核苷酸含量有一定的改变，这些改变可能是脾虚时胃粘膜代谢和功能变化的病理基础。

Methodology of Canine/Feline YNSA and Tail Acupuncture

BackgroundYamamoto New Scalp Acupuncture (YNSA) is a well-known acupuncture system for human patients which was developed by Dr. Yamamoto.ObjectiveMy aim was to transpose the human YNSA map onto canines and felines.MethodI started researching a canine/feline YNSA map in 2002. I investigated approximately 3,000 canines and felines for YNSA and 2,500 for Tail Acupuncture. The ratio of canines and felines was 6 to 4. I researched and found all the equivalent points by palpating animal patients on the basis of an exact Neck Diagnosis.ResultsI nearly completed the map in 2006. The points in the occipital region are incomplete and my research is still in progress. In the process of researching canine/feline YNSA points, I accidentally found the other microsystems around the tail and named it “Tail Acupuncture”.ConclusionsYNSA and Tail Acupuncture are acupuncture systems utilizing microsystems and support each other in canines and felines. The merits of YNSA and Tail Acupuncture are 1) immediate effects, such as in cases of lameness, 2) simplicity in finding the exact points to treat and 3) the scalp and the tail can be utilized separately or together as treatment zones, according to the situation.     

蜂蜜炼制前后黄酮类成分种类和含量变化分析

目的研究中药辅料蜂蜜炼制前后黄酮类成分变化。方法参考《中药药剂学》,对不同来源的6种蜂蜜进行炼制。供试品经固相萃取法富集黄酮类成分。采用高效液相色谱-三重四级杆串联质谱(HPLC-TQ-MS)法测定,Thermo Accucore RP-MS色谱柱(100 mm×2.1 mm,2.6μm),以0.1%甲酸水溶液-甲醇为流动相进行梯度洗脱,体积流量0.3 m L/min,柱温30℃。质谱条件:采用电喷雾离子源(ESI),正离子检测模式,多反应监测模式(MRM)扫描分析。结果蜂蜜中共检测到12种黄酮类成分,包括黄酮苷元、二氢黄酮苷元和异黄酮苷元。黄酮苷元有8种:槲皮素、桑黄素、木犀草素、山柰酚、芹菜素、汉黄芩素、高良姜素和白杨素;二氢黄酮苷元有3种:短叶松素、柚皮素和乔松素;异黄酮苷元染料木素。不同蜜源蜂蜜所含黄酮类成分种类和含量存在明显差异。6个蜂蜜样品炼制后,都发现了蜂蜜中没有报道过的芦丁和芸香柚皮苷,12种检测到的蜂蜜黄酮类成分在炼制后其量都有不同程度的变化,椴树蜜的槲皮素、桑黄素、木犀草素、山柰酚、芹菜素、汉黄芩素、乔松素和白杨素量均有增加,短叶松素、柚皮素和高良姜素量没增加反而还有下降的;洋槐蜜中除芹菜素量增加不明显外,其余均有所增加,尤其是槲皮素和桑黄素增加的较为明显;百花蜜和枣花蜜12种黄酮类成分量均显著增加。结论炼制可造成蜂蜜中黄酮类成分的种类和含量发生改变。     

Chinesische Orthopädie: Teil 1: Die Zukunft der Akupunktur in der Postmoderne

The locomotor system is one of the major fields of application for acupuncture. The results of the large acupuncture studies funded by German Health Insurances from 2000 until 2006 are impressive and repressive: they restrict acupuncture application by allocation of reimbursement and create the necessity of reorientation, since acupuncture can neither be adequately described nor prescribed solely on the basis of disease entities. Regarding these disease entities, it seems rather necessary to analyse the layers of problems and formulate a hierarchy of therapeutic goals instead. Only in this way the effects of acupuncture, related techniques and further therapeutic modalities can be matched with the set of objectives. The article presents general principles and follows their application from biological aspects to implications for the locomotor system and consequences for the application of physical therapy. The manual of acupuncture focuses on therapeutic effects and objectives first, and then goes on to sketch simple therapeutic strategies and finally complex approaches within acupuncture. These may encompass acupuncture, microsystem acupuncture and complex therapeutic modes.     

Patientin mit chronisch rezidivierenden Gelenks- und Wirbelsäulenschmerzen

Background

Acupuncture as a regulative therapy is well-suited for the treatment of functional, reversible disorders. Additionally, the WHO recommends its application for pain therapy in cases of arthritis and back pain due to various causes. This case study should clarify which paths to take in the case of a multi-morbid patient suffering from chronic pains due to polyarthrosis.

Objective

Pain reduction and improvement of quality of life as well as improvement of sleep quality.

Methods

Annual treatment series consisting of 10 sessions each, one session per week.

Results

short-term pain reduction before undergoing endoprosthetic surgery; considerable improvement of general status and sleep.

Conclusions

Acupuncture may bring temporal relief in cases of chronic pain due to osteoarthritis and should therefore be applied in combination with western medicine. Acupuncture is particularly well-suited to treat the co-emergent vegetative symptoms.     

Fallbericht: Patientin mit Schlafstörung

Background

Since the onset of her menopause about ten years ago, a sixty-year old patient has been suffering from hot flashes and sleep disorders causing her to become increasingly anxious and nervous. As the patient's mother had died of breast cancer, substitution of hormones was not advisable. Relaxation methods such as Yoga and Autogenic Training could only mildly alleviate the symptoms.

Objective

To effectively treat the sleep disorder, improve quality of life, lessen frequency and severity of hot flashes

Methods

Weekly sessions with ear- and body acupuncture for ten weeks

Results

After the third acupuncture session the patient reported a decrease of nightly waking episodes but suffered from acute pain in the neck as well as shoulder region. After nine therapy sessions, the patient reported a 50% decrease of nightly waking episodes. The hot flashes, however, remained unchanged.

Discussion

In this case, acupuncture significantly improved the patient's sleeping disorder. It also reduced the symptoms of anxiety and nervousness. Other menopausal symptoms such as hot flashes and dryness of mucous tissues, could not be influenced.
