人白细胞介素2基因转移表达及抗乙型肝炎病毒和诱导LAK细胞活性的研究

为了探讨白细胞介素（ＩＬ）－２转基因表达抗乙型肝炎病毒（ＨＢＶ）的作用，应用逆转录病毒载体ｐＺＩＰＳｖ（Ｘ）－包装细胞系ＰＡ３１７基因转移系统，研究了人ＩＬ－２ｃＤＮＡ转移和表达，以及抗ＨＢＶ和诱导淋巴因子激活的杀伤细胞（ＬＡＫ细胞）的作用。所构建的人ＩＬ－２重组表达载体ｐＺＩＰｈｕＩＬ－２，以ＤＮＡ－磷酸钙共沉淀技术转染ＰＡ３１７细胞，筛选到Ｇ４１８抗性克隆，分泌假病毒颗粒达１０６ＣＦＵ／ｍｌ。以假病毒颗粒感染２．２．１５细胞系及正常人外周血单个核细胞，分泌ＩＬ－２水平可达６ＩＵ／ｍｌ，明显抑制２．２．１５细胞ＨＢｓＡｇ的分泌表达，与１００ＩＵ／ｍｌ重组的ＩＬ－２一样可诱导出相似的ＬＡＫ细胞活性。而不含ＩＬ－２ｃＤＮＡ的ｐＺＩＰＳＶ（Ｘ）的假病毒颗粒则无此作用。提示逆转录病毒载体。包装细胞系可以成功地实现人ＩＬ－２ｃＤＮＡ的转移和低水平的分泌和表达，并可明显抑制２．２．１５细胞分泌ＨＢｓＡｇ及诱导ＬＡＫ细胞活性。

用IL－2／LAK细胞对中晚期癌症病人细胞免疫的影响

为了探讨ＩＬ－２／ＬＡＫ细胞对中晚期癌症病人细胞免疫的影响，用３Ｈ－ＴｄＲ掺入ＤＮＡ法测定了１７例中晚期癌症病人在ＩＬ－２／ＬＡＫ细胞治疗前后外周血加ＰＨＡ或不加ＰＨＡ淋巴细胞体外增殖试验，结果显示无论空白对照（１１／１６）还是ＰＨＡ诱导的Ｔ淋巴细胞增殖试验（１２／１６），ｃｐｍ值较治疗前均有明显的提高（Ｐ＜０．０５，Ｐ＜０．０１）；在Ｔ细胞亚群的测定中，ＩＬ－２／ＬＡＫ细胞治疗前后比较，ＣＤ３＋和Ｃ８＋细胞都未发现明显的差异，只有Ｃ４＋细胞较治疗前（１３／１７）有了显著提高（Ｐ＜０．０１）；ＮＫ细胞虽未达到正常水平，但也显示较治疗前有显著增高的倾向；结果表明，ＩＬ－２／ＬＡＫ细胞疗法既对肿瘤细胞有直接杀伤作用，也对细胞免疫起了明显的促进作用。

烧伤后白介素2与白介素2受体基因表达的变化及人参茎叶皂甙的调节作用

研究了不同程度烧伤小鼠淋巴细胞白介素２（Ｉｎｔｅｒｌｅｕｋｉｎ２，ＩＬ－２）ｍＲＮＡ及ＩＬ－２受体α（ＩＬ－２Ｒα）ｍＲＮＡ的变化，并观察人参茎叶皂甙的体内外调节作用。结果显示，烧伤后ＩＬ－２ｍＲＮＡ及ＩＬ－２ＲαｍＲＮＡ水平均降低，且同伤情变化关系密切。伤后ＩＬ－２及ＩＬ－２Ｒα的变化分别同ＩＬ－２ｍＲＮＡ、ＩＬ－２ＲαｍＲＮＡ的变化呈非常显著的正相关。人参茎叶皂甙皮下注射（５０ｍｇ·ｋｇ（－１）·ｄ（－１），连续４ｄ）可显著提高烧伤小鼠淋巴细胞ＩＬ－２ｍＲＮＡ及ＩＬ－２ＲαｍＲＮＡ水平，并促进ＩＬ－２生成及ＩＬ－２Ｒα表达。人参茎叶皂甙体外（０．１至１００μｇ／ｍｌ）也可拮抗烧伤小鼠ＩＬ－２ｍＲＮＡ及ＩＬ－２ＲαｍＲＮＡ的受抑状态。上述结果表明，烧伤可致淋巴细胞ＩＬ－２及ＩＬ－２Ｒα的基因表达受抑，进而导致ＩＬ－２的生成及ＩＬ－２Ｒα的表达减少。人参茎叶皂甙对这一变化具有明显的拮抗效应。     

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.

Acupuncture Treatment of Chest Bi Syndrome

CASE HISTORY A male,a retired officer of 61 years old,paid his first visit on May 12,2006.The patient stated that 2 weeks before he suddenly got paroxysmal precordial choking pain,with irregular attacks.Each attack would last several seconds to several minutes.The attack was accompanied with heavy oppressed sensation in the precordial region,palpitation,lassitude,and in severe cases,sweating,which was once diagnosed by a hospital as'coronary heart disease'.Recalling the case history,the patient said that several days before he got angry with others because of some affairs in work,and he was not so used to the life pattern since he had just retired from his busy working post.At usual times,he was quick tempered and peevish.In recent days,he had poor appetite,and loose stool.
