目的探讨镍铬合金和钛合金烤瓷冠修复对牙周组织及龈沟液中细胞因子的影响。方法80例共80颗牙按照烤瓷冠金属材料不同分为镍铬合金组(n=40,采用镍铬合金烤瓷冠修复)和钛合金组(n=40,采用钛合金烤瓷冠修复),以对侧同名健康天然牙作为对照。比较两种烤瓷冠修复后1年对牙龈的影响,检测患牙和对照牙龈沟出血指数(SBI)、菌斑指数(PLI)、探诊深度(PD);测定并比较龈沟液(GCF)中自细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、天冬氨酸转氨酶(AST)水平。结果镍铬合金组对牙龈外观的影响大于钛合金组(P〈0.01);修复后1年,镍铬合金组修复牙SBI及PD均显著大于对照牙(P〈0.05),PLI与对照牙无差异(P〉0.05);钛合金组修复牙SBI较对照牙增大(P〈0.05),PLI及PD与对照牙无差异(P〉0.05);镍铬合金组修复牙GCF量较对照牙增多,IL-1β、TNF-α及AST水平均较对照牙升高(P〈0.05、P〈0.01),而钛合金组修复牙GCF量、IL-1β、TNF-α及AST水平较对照牙无差异(P〉0.05)。结论镍铬合金烤瓷冠对牙龈和牙周组织有明显不利影响。而钛合金烤瓷冠对牙龈和牙周组织的影响较小。值得临床借鉴。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
