三叶因子家族在胃癌及癌前病变组织中的表达及其意义

目的探讨三叶因子家族（TFF）在胃癌及癌前病变中的表达及其意义。方法选择经胃镜活检并经病理证实的基本正常或轻度浅表性胃炎患者20例（正常胃黏膜组）、慢性浅表性胃炎伴胃黏膜肠上皮化生患者30例（肠上皮化生组）、慢性萎缩性胃炎伴胃黏膜不典型增生患者24例（不典型增生组）和胃癌患者40例（胃癌组）。采用免疫组化S—P法检测上述受检者的手术标本中TFF1、TFF2和TFF3的表达情况,并分析TFF与胃癌组织学类型、分化程度、浆膜浸润、淋巴结转移及TNM分期等临床病理特征的关系。结果TFF1、TFF2在正常胃黏膜、不典型增生胃黏膜、肠上皮化生胃黏膜及胃癌组织中均有表达,二者表达强度依次呈递减趋势（P〈0．05）;TFF3在正常胃黏膜没有表达,而在肠上皮化生胃黏膜、不典型增生胃黏膜和胃癌组织中均有表达,表达强度依次呈递增趋势（P〈0．05）。在胃癌组织中,TFF1在低分化胃癌中的表达阳性率显著高于中高分化胃癌（73．7％与38．1％,P〈0．05）,而TFF2在中高分化胃癌中的表达阳性率显著高于低分化胃癌（90．5％与47．4％,P〈0．01）,二者均与胃癌是否发生浆膜浸润、是否有淋巴结转移及TNM分期无关（P〉0．05）;TFF3在有浆膜浸润、伴淋巴结转移和分期较晚（Ⅲ/Ⅳ期）胃癌组织中的表达阳性率[分别为91．7％、88．9％和95．0％]显著高于无浆膜浸润及淋巴结转移和Ⅰ／Ⅱ期的胃癌组织（37．5％、46．2％和55．0％,P〈0．01）,但与胃癌组织的分化程度无关（P〉0．05）;TFF1、TFF2和TFF3在弥漫型胃癌组织中的表达阳性率[分别为75．0％、82．1％和85．7％]显著高于肠型胃癌组织[分别为25．0％、41．7％和50．0％],差异有统计学意义（P〈0．05）。结论TFF1和TFF2在正常胃黏膜-肠上皮化生-不典型增生-胃癌组织中的表达逐渐减少以及TFF3的表达逐渐增多可能在胃癌发生中起重要作用。TFF1和TFF2可能是胃癌抑制因子,其表达减少可能使胃癌恶性程度增加;TFF3可能与胃癌浸润转移有关,其表达增多则预后不良。

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.     

Insomnia Due to Deficiency of Both the Heart and Spleen Treated by Acupuncture-Moxibustion and Chinese Tuina

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.
