目的: 观察昆明山海棠(THH)对胶原性关节炎(CIA)大鼠免疫功能的干预作用,探讨其可能的作用机制。 方法: SD大鼠50只,随机分为正常组(n=10)和CIA模型制备组(n=40),用鸡Ⅱ型胶原(CⅡ)诱导大鼠制备CIA模型。再将造模成功的36只大鼠随机分为模型组、地塞米松组及200和400 mg·kg^-1THH干预组。在实验过程中观察各组大鼠足爪肿胀度和关节炎指数(AI)等变化。实验第35天,采用ELISA法检测血清中抗CⅡ抗体水平;MTT法检测脾T细胞和B细胞增殖活性;ELSIA法检测脾组织白细胞介素12(IL-12)、IL-23和肿瘤坏死因子α(TNF-α)水平;取各组大鼠足爪组织行HE染色,观察组织病理学变化。 结果: 与正常组比较,模型组大鼠AI明显上升(P<0.01),血清抗CⅡ抗体水平、脾T细胞和B细胞增殖活性、脾组织中IL-12、IL-23和TNF-α水平明显升高(P<0.01);大鼠足爪皮下组织细胞排列紊乱且有大量炎性细胞浸润及血管增生。与模型组比较,400 mg·kg^-1THH干预组大鼠一般状况得到明显改善,足爪肿胀度和AI明显下降(P<0.01),脾T细胞和B细胞增殖活性明显下降(P<0.01),血清中抗CⅡ抗体水平明显降低(P<0.01),脾组织中IL-23、TNF-α和IL-12水平均明显降低(P<0.01),大鼠足爪组织病理学改变明显减轻。200 mg·kg^-1THH组大鼠上述指标无明显变化(P>0.05)。 结论: 高剂量(400 mg·kg^-1)THH对CIA大鼠关节炎有明显抑制作用,其机制可能是THH能明显抑制T和B淋巴细胞的增殖反应,并抑制脾组织中IL-23、TNF-α和IL-12和血清中抗CⅡ抗体水平,进而明显改善大鼠足爪组织病理学变化。

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.

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.
