| 1 | Mycoplasma infections and different human carcinomas显示文摘AIM To explore relationships between human carcinomas and mycoplasma infection.METHODS Monoclonal antibody PD4, which specifically recognizes a distinct protein from mycoplasma hyorhinis, was used to detect mycoplasma infection in different paraffinembedded carcinoma tissues with immunohistochemistry. PCR was applied to amplify the mycoplasma DNA from the positive samples for confirming immunohistochemistry.RESULTS Fifty of 90 cases (56%) of gastric carcinoma were positive for mycoplasma hyorhinis. In other gastric diseases, the mycoplasma infection ratio was 28% (18/49) in chronic superficial gastritis, 30% (14/ 46) in gastric ulcer and 37% (18/ 49) in intestinal metaplasia. The difference is significant with gastric cancer (X2=12.06, P<0.05). In colon carcinoma, the mycoplasma infection ratio was 55.1% (32/58), but it was 20.9% (10/49) in adenomarous polyp (X2=13.46, P<0.005).Gastric and colon cancers with high differentiation had a higher mycoplasma infection ratio than those with low differentiation (P< 0.05). Mycoplasma infection in esophageal cancer, lung cancer, breast cancer and glioma was 50.9% (27/53), 52.6% (31/ 59), 39.7%(25/63) and 41% (38/91), respectively. The mycoplasma DNA was successfully amplified with the DNA extracted from the cancer tissues that were positive for mycoplasma infection (detected with antibody PD4).CONCLUSION There was high correlation between mycoplasma infection and different cancers, which suggests the possibility of an association between the two. The mechanism involved in oncogenesis by mycoplasma remains unknown. | Su Huang Ji You Li Jan Wu Lin Meng Cheng Chao Shou Beijing Institute for Cancer Research, Peking University School of Oncology, Beijing 100034.

| 3 | ECONOMIC GROWTH AND CYCLES IN MODERN CHINA显示文摘If the theory of cyclical fluctuation can be applied to modern China, the economic development ofChina in this period can be seen as consisting of several stages. At each stage as well as in the wholeperiod, chosen index system is likely to help measure the growth rate. By vertical and horizontal com-parison, this paper will try to settle the disputes on China’s modern economic development. | Liu Foding Wang Yuru Yu Jianwei 1937- Professor of Institute of Economics of NANKAI UNIVERSITY.

| 4 | 经皮自体骨髓移植治疗骨不连——骨髓母细胞数量和浓度对治疗的影响显示文摘背景:自髂嵴部位取包含有母细胞成份的骨髓,其可以通过促进骨的愈合来治疗骨不连。然而,有关促进骨修复所需的母细胞的数量、浓度的研究较少。本研究主要探讨母细胞移植治疗骨不连的有效细胞数量和浓度,评估移植后骨痂形成的数量及临床愈合率。
方法:在60例无感染的萎缩性胫骨骨不连患者双侧髂嵴前部吸取骨髓后,经细胞分离器进行浓缩,然后注射入骨折断端。每个骨折部位均注入20cm^3的浓缩骨髓。其母细胞数量通过纤维母细胞集落形成单位数量仪来测定。其形成的矿化骨的数量通过术前CT扫描与注射后4个月复查的CT扫描结果之间的比较来确定。
结果:吸取的骨髓中母细胞计数浓缩前平均为(612±134)个/cm^3(12~1224个/cm^3),浓缩后平均为(2579±1121)个/cm^3(60~6120个/cm^3)。每例骨不连部位注入的纤维母细胞集落形成单位数量平均为51×10^3。60例中有53例骨折愈合,愈合组患者注入的骨髓母细胞数都在1500个/cm^3以上,平均含母细胞数为(54962±17431)个。然而在7例仍然无法愈合的病例中,注入的骨髓母细胞浓度为(634±187)个/cm^3,细胞的总数量为(19324±6843)个,与愈合组相比不愈合组的细胞浓度和数量均较低,两组差异有统计学意义(分别为p=0.001,p〈0.01)。4个月后CT显示矿化的骨痂数量为0.8~5.3cm^3(平均3.1cm^3)。统计学结果显示矿化骨痂的数量和纤维母细胞集落单位的数量及浓度均呈正相关(分别为p=0.04,p=0.01)。而愈合时间和纤维母细胞集落单位的浓度呈负相关(p=0.04)。
结论:经皮自体骨髓移植是治疗胫骨骨干萎缩性骨不连的安全而有效的方法。然而,其有效性与移植骨髓中母细胞的数量有关,自髂嵴获取的骨髓如果不经过浓缩处理,其母细胞数量并不能达到治疗骨不连的理想数目。
