血管紧张素Ⅱ及醛固酮阻滞剂对心肌梗死大鼠骨桥蛋白表达的影响

 【目的】研究血管紧张素Ⅱ及醛固酮阻滞对心肌梗死大鼠非梗死区心肌组织骨桥蛋白（OPN）表达的影响。【方法】将心肌梗死后24h存活大鼠随机分为3组：盐水组（15只，5mL／d），培哚普利组（18只，2mg／kg·d）和螺内酯组（17只，20mg／kg）。灌胃给药；另设假手术组（15只）作对照。分别于心肌梗死后6周：导管法测定左室有创血流动力学；组织学方法检测非梗死区胶原纤维沉积和心肌细胞横径；Western blot检测非梗死区心肌组织OPN表达。【结果】①假手术组大鼠心肌组织Western blot未检测到OPN表达，心肌梗死大鼠6周后非梗死区心肌组织有大量OPN表达，培哚普利及螺内酯治疗均能显著抑制该蛋白的上调，差别均有统计学意义（P均〈0．01）。②与假手术组相比，所有心肌梗死大鼠均出现显著的心肌间质纤维沉积，左室重量指数增大，非梗死区心肌细胞横径增加，差别均有统计学意义（P均〈0．01）。与盐水组相比，培哚普利及螺内酯组心肌问质纤维沉积减轻，左室重量指数及非梗死区心肌细胞横径降低，差别均有统计学意义（P均〈0．01）。③与假手术组相比，所有心肌梗死大鼠6周后左室内收缩压（LVSP）和±dp/dtmax均显著下降，左室舒张末期压（LVEDP）显著上升，差别均有统计学意义（P均〈0．01）；与盐水组相比，培哚普利与螺内酯组大鼠心功能显著改善，差别均有统计学意义（P均〈0．01）。【结论】心肌梗死后大鼠非梗死区心肌组织出现大量OPN表达及显著的心室重构；血管紧张素Ⅱ及醛固酮阻滞均能显著抑制心肌梗死大鼠OPN的表达，并能改善心肌的纤维化，改善心脏功能。     

培哚普利对心肌梗死大鼠左室重构和心肌组织osteopontin蛋白表达的影响

目的观察血管紧张素转换酶抑制剂培哚普利对心肌梗死大鼠左室重构和心功能的影响,并探讨osteopontin蛋白在其中的作用。方法将成年雄性SD大鼠随机分为3组:假手术组,心肌梗死盐水组和心肌梗死培哚普利组。后两组动物在冠状动脉左前降支结扎第2天起给予生理盐水或者培哚普利灌胃,1次/d。4周后测定有创左室血流动力学,超声心动图测量左室内径和射血分数,组织学方法检测非梗死区心肌细胞直径和胶原纤维沉积,Westernblot检测心肌组织osteopontin蛋白表达水平。结果与假手术组相比,所有心肌梗死大鼠(盐水组和培哚普利组)均出现显著的左室收缩和舒张功能障碍,表现为LVEF、LVSP和±dp/dtmax下降,LVEDP显著升高。同时左室重量与体质量比值升高,LVEEDD和LVESD增大,非梗死区心肌细胞横径增加,心肌间质胶原纤维沉积增加,提示显著的左室重构。与盐水组相比,培哚普利治疗显著改善心肌梗死大鼠心功能,预防左室扩大,减轻非梗死区心肌细胞肥大和心肌间质胶原纤维沉积。Westernblot未检测到osteopontin蛋白在假手术大鼠心肌组织表达,在心肌梗死大鼠心肌组织有大量osteopontin蛋白表达,该上调的蛋白能被培哚普利治疗显著抑制。结论培哚普利抑制心肌梗死大鼠左室重构,改善心功能,可能与其抑制osteopontin蛋白表达有关。     

培哚普利对兔急性心肌梗死再灌注后无复流的干预作用

目的评价培哚普利对兔急性心肌梗死（AMI）再灌注后的干扰素（IFN）-γ影响及对无复流的防治作用。方法新西兰大白兔24只随机分成对照组、培哚普利组和假手术组,每组8只。冠状动脉结扎1 h,松解2 h制备AMI再灌注模型。采用放射免疫方法心肌测定AngⅡ,采用免疫组织化学的方法测定心肌IFN-γ的表达,并进行心肌病理染色,计算无复流面积。结果对照组及培哚普利组复流区和无复流区心肌组织中AngⅡ含量均显著高于正常区心肌组织（P〈0.01）,且无复流区AngⅡ含量高于复流区（P〈0.01,培哚普利组P〈0.05）,培哚普利组心肌AngⅡ均显著低于对照组（复流区P〈0.01,无复流区P〈0.05）;对照组及培哚普利组复流区、无复流区心肌IFN-γ表达均显著高于正常区（P均〈0.01）,且无复流区IFN-γ表达高于复流区（P均〈0.01）,培哚普利组与对照组比较,IFN-γ在复流区和无复流区表达明显减弱（P均〈0.01）。培哚普利组与对照组相比,LA差异无统计学意义（36.58%±2.35%vs 37.15%±2.56%,P〉0.05）,ANR显著降低（47.36%±4.19%vs 76.54%±4.52%,P〈0.01）。结论兔AMI再灌注后局部心肌肾素血管紧张素系统（RAS）明显激活,AngⅡ生成及释放增加,其增强与IFN-γ升高有关。培哚普利通过抑制IFN-γ介导的炎症反应,抑制AngⅡ生成及释放增加,从而起到防治无复流的作用。

贝那普利联合螺内酯对大鼠心室重构的干预

目的以内皮素（ET）及一氧化氮（NO）为心室重构观察指标研究贝那普利联合螺内酯应用对心室重构大鼠的影响。方法结扎Wistar雄性大鼠腹主动脉建立压力超负荷性心室重构大鼠模型。48只建模后存活大鼠随机分为4组（每组12只）：贝那普利联合螺内酯组（贝那普利10mg·kg-1.d-1,螺内酯15mg·kg-1.d-1）,贝那普利组（贝那普利20mg·kg-1.d-1）,螺内酯组（螺内酯30mg·kg-1.d-1）,生理盐水组（生理盐水10ml.kg-1.d-1）;不结扎腹主动脉的12只作为假手术组（蒸馏水10ml.kg-1.d-1）;各组每天灌胃给药1次,共6周。给药6周后用放免法测定心肌中ET和血浆中NO含量。结果建模组与假手术组相比,心肌中ET含量明显升高（P〈0.05）,血浆NO水平明显降低（P〈0.05）,表明大鼠心室重构模型建立成功。贝那普利联合螺内酯组及贝那普利、螺内酯单独给药组均能降低心肌ET的含量及升高血浆中NO含量（P〈0.05或P〈0.01）,但贝那普利联合螺内酯组比贝那普利组、螺内酯组作用更明显（P〈0.05）。结论联合应用贝那普利与螺内酯可更有效逆转大鼠心室重构。

Acupuncture Treatment of Vomiting

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.     

Qiu Baoguo''''s Experience in Treating Consumptive Syndromes after Radio-Chemotherapies

Radiotherapy and chemotherapy are the important modern medical therapies for malignant tumors,yet they can also bring about serious local and systemic toxic side reactions so to decrease the patient;'s life quality,manifested by a series of consumptive symptoms.Having engaged in the combined work of Chinese and western medicine for nearly 50 years,the research fellow Qiu Baoguo in Henan Provincial Academy of TCM has developed his unique views on the TCM study of consumptive syndromes.The author of this essay had once the fortune tO follow Dr.Qiu in clinic,and specially would like to introduce in the following Dr.Qiu's experience in treating consumptive syndromes after radio-chemotherapies for patients with malignant tumor.

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.     

Analysis of CK-19,PDX-1,Nestin,Ngn3 in different donor islet purity in rats

Objective: To investigate if there are the CK-19, PDX-1, Nestin, Ngn3 positive cells in the donor islets of different purity in rats. Methods: Thirty male adult SD rats were randomly divided into 3 groups. Islets were isolated using digestion by ductal injection of collagenase. Group Ⅰ (n=10): Separating cell preparations were not purified, Group Ⅱ(n=10): Islet sediment was purified with 25% Ficoll400 ,Group Ⅲ (n=10): Islet sediment was purified with 25% and 11% Ficoll-400. The levels of protein of CK-19, PDX-1, Nestin and Ngn3 were detected by immunohistochemistry and the mRNA of CK-19, PDX-1, Nestin, Ngn3 was amplified by RT-PCR. Results: After two different purification methods applied, three islet preparations of different purities were obtained. The difference of islet purity was significant among various groups (P＜0.05). Compared with group Ⅱ and group Ⅲ,the protein and mRNA of CK-19, PDX-1, Nestin,Ngn3 were both higher in group Ⅰ; group Ⅲ was poorly expressed. Conclusions: The three different islet purity donor islet have different CK-19, PDX-1, Nestin, Ngn3 positive cells within them, indicating that there are some islet stem cells in the purified donor islet.     

A preliminary screening study on the associated proteins in human psoriasis vulgaris by serum proteomics technologies

Objective：To investigate the optimum screening conditions of associated proteins in human psoriasis vulgaris by serum proteomics technique, and to screen the different expression proteins related with psoriasis vulgaris. Methods：Serum samples of peripheral blood were collected from newly diagnosed psoriasis vulgaris patients in the clinic, and 20 matched healthy persons. Serum albumin IgG was removed by filtering with ProteoExtract Albumin/IgG. After comparative proteomics analysis the different protein spots were identified using 2-DE and MS. Results ：Electrophoresis figures with high resolution and reproducibility were obtained. Three different expression proteins were found only in the serum from psoriasis vulgaris patients, while nine other different proteins expressing from healthy volunteers. Conclusion：The protein expression was different in the serum between the psoriasis vulgaris patients and healthy volunteers. It was hoped that we could find the biomarkers related to psoriasis vulgaris by using proteomics.
