OBJECTIVE:To systematically review the relationship of clinical efficacy between XPD Lys751Gln (A/C),XPD Asp312Asn(G/A)and platinum-based chemotherapy in patients with advanced non-small cell lung cancer(NSCLC),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed, Cochrane Library, EMBase, Medline, CJFD,VIP database and WanFang database,studies about the effects of XPD Lys751Gln and XPD Asp312Asn polymorphism on ef-fectiveness,clinical outcomes and adverse drug reaction of platinum-based chemotherapy in advanced NSCLC patients were collect-ed,and Meta-analysis was performed by using Rev Man 5.3 software. RESULTS:Totally 30 studies were included,involving 5 028 patients. Genetic testing showed that XPD Lys751Gln divided into mutant gene (Lys/Gln + Gln/ Gln) and wild-type gene (Lys/Lys),while XPD Asp312Asn divided into mutant gene (Asp/Asn + Asn/Asn) and wild-type gene (Asp/Asp). Results of Me-ta-analysis showed,the progression-free survival (PFS) of Lys/Gln+Gln/Gln patients with platinum in XPD Lys751Gln polymor-phism was obviously lower than Lys/Lys patients [OR=-1.12,95%CI(-1.73,-0.50),P<0.001],while there was no significant difference in the chemotherapy effectiveness and total survival period. The effective rate of Asp/Asn+Asn/Asn patients for platinum in XPD Asp312Asn polymorphism was lower than Asp/Asp patients [OR=0.80,95%CI(0.68,0.96),P=0.02],while there was no significant difference in the total survival period and PFS. Meanwhile,the incidence of Ⅲ-Ⅳ level gastrointestinal adverse reac-tions of Lys/Gln+Gln/Gln with platinum in XPD Lys751Gln polymorphism was higher than Lys/Lys patients [OR=0.43,95%CI (0.20,0.94),P=0.03],and there was no significant difference in Ⅲ-Ⅳ level blood system adverse reactions. CONCLUSIONS:XPD Lys751Gln polymorphism may be associated with PFS and Ⅲ-Ⅳ level gastrointestinal adverse reactions for advanced NSCLC patients with platinum-based chemotherapy,while XPD Asp312Asn polymorphism may have effect on platinum-based chemotherapy,both of them may be as estimate the chemotherapy effect and prognosis detection index of platinum-based chemo-therapy.

BACKGROUND: Microglial cells are prominently involved in certain neurologic diseases such as Parkinson disease and Alzeheimer disease. In vitro primary culture is commonly used in studies on the functions of microglia.However, these classical culture methods have some defects including complex procedures and low out-put.OBJECTIVE: To establish a simplified high-output primary culture of microglia.DESIGN: An explorative experiment with microglial cells as the single sample.SETTING: Department of Neurology, Affiliated Union Hospital, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The study was finished at the Central Laboratory of Union Hospital from April to October 2004. Microglial cells were obtained from 10 newborn(one day) male Kunming mice that were selected.METHODS: The author' s culture method was based on McCarthy method, we developed a new culture method and made some improvements,including the increased cell density for primary culture and nutritional deprivation. The microlglial cells were isolated with low-concentration trypsin-EDTA(ethylene diamine tetraacetic acid) digestion and immunochemically labeled with MAC-1 antibody, so as to measure the output and purity of microglia.MAIN OUTCOME MEASURES: ① Morphologic features of microglial cells, observed with inverted microscope; ② Purity and activity of microglia cultured with these two methods, were measured immunohistochemically.RESULTS: For microglia cultured with McCarthy method, the culture cycle was 20 days and the output was 2 × l05 cells per flask with a purity of 95% -97%. The new method shortened the culture cycle to 15 days and the output reached 1 × 106 cells per flask with a purity of 96-98%. Cell purity and activity had no significant difference between these two culture methods.CONCLUSION: The new method has a similar purity and activity with classical method; however, it may simplify procedures, shorten cycle, and increase output, and therefore can be a useful method for studies on microglia function and for nerve repair.
