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.

Objective To explore the relationship between the status of the cervical lymphatic metastasis of papillary thyroid carcinoma(PTC)at cNo stage and tumor recurrence and the patient' s prognosis.Methods The clinical data of 498 cNo PTC patients admitted from 1986 to 1990 were retrospectively analyzed.Results All the patients were followed up for more than 10 years.16 patients died of PTC,among them 3 for metastasis,13 for local recurrence.The total cervical lymphatic metastasis rate in these 498 patients was 52.2％,in 260 cases in which detailed data were available: rate was 14.1％ in zone Ⅱ,27.1％ in zone Ⅲ,24.6％ in zone Ⅳ,12.5％ in zone Ⅴ,and 20.1％ in zone Ⅵ respectively.According to the appearances of microscopic pathology,the cervical lymphatic metastasis rates in 498 cases of cNo PTC were collected as following: uncapsuled group was 65.6％,extracapsular group was 64.5％,extralobal group was 56.5％,involved the surrounding tissue and structure group was 52.0％,focal cancerous focus group was 33.3％,latent sclerosis group was 26.9％,encapsuled and introcapsule group was 0.The cervical recurrence rate was only 2％ in the complete function neck dissection group and 9.9％ in the selective center neck dissection group.Conclusions In cNo PTC the most common cause of death was local recurrence.Prophylactic function complete neck dissection should be performed for cNo PTC cases of highly invasive type such as without tumor capsule,extracapsular,extralobal or surrounding tissue invasion.

Objective To understand and raise the level of osteopomsis-relied knowledge, attitudes and behaviors for prevention and treatment of osteoperosis(OP)in residents of a community. Methods A survey was performed with a questionnaires method targeting at the elderly residents in Changfeng community.The survey was conducted with a specifically designed questionnaire,followed by a second survey.during which health edueafion was stressed.Data were analyzed with SPSS 11.0 software. Results In 3524 residents.3367 responded positively.The ratio of male to female was 1:2.10.The average age of the respondents was 61.34 years.They demonstrated a low level of OP KAP.76.72% of them heard the term of OP,60.11% had a correct judgment of their own bone heahh,42.26% knew the cause of OP.and 37.75% understood the diagnostic method of OP.The level of OP KAP varied in different groups of targeted residents.Of all the questions.the understanding of the diagnosis ranked the lowest.2281 people participated in the second survey,which showed improvement in their OP KAP.The difference was statistically significant.1439 people auended the consultation.99.86% of them considered the activities necessary,96.92% expressed their satisfaction,and 98.54% planed tO take measures to improve their bone health.Conclusion The poor understanding of bone heaith status and the knowledge about prevention and treatment of OP is why it is widely spread in the modem society,which however Call be improved by education.

Objective:To investigate the neuropsychological characteristics of Chinese agraphia caused by basal ganglia(BG)infarction.Methods:The writing abilities of 40 patients with BG infarction were detected by Chinese agraphia battery(CAB),and all the writing scores and agraphia quotient were calculated.The head CT/MRI images in agraphia and non-agraphia groups were standardized,the infarction were revealed and the superposition of two-dimensional arrays were performed,so that the central tendency of infarction was visually displayed.Results: Among the 40 patients,21 had left BG infraction,and 17 had agraphia;19 had right BG infraction,and 4 had agraphia.The two-dimensional superimposing neuroimages showed that BG infarctions caused agraphia was mostly in the left BG,including the left putamen,the head and body of the caudate nucleus,but there were fewer infarctions in the right putamen and the body of the candate nucleus.BG infarction caused agraphia was mostly aphasic agraphia,which was characterized by the orthographic disorders,paragraphia,and grammar mistakes.Conclusions: BG infarction may result in aphasic agraphia,which suggested that BG is involed in writing and processing,and it is the subcortical center of this advanced neurofunction in writing.
