Objective To observe the curative and poison side effect of the chemical and heat treatment in treating the middle and late period NSCLC. Methods There are forty-seven middle and late patients, all of them for three weeks by using the Hp plan. The heat treatment group(24) :on the first day,the patients use the heat treatment twice a week,four times a period;the comparision group(23) :give them the chemical treatment by using the same method,but dont give them the heat treatment. To observe the recent treatment effect and the poison side effect. Re-suits The heat treatment group is better than the comparision group. But it doesn't have the statistic sianificance(P>0.05 ), then we observe the pathology, the effect of the glandular cancer in heat treatment group (46.2%) is better than the comparision group(25.0% ) ( P<0.05 ). The poison side effect mostly depends on the first and second de-gree. The heat treatment group is better than the comparision group. But it has no statistic significance ( P>0.05 ).Conclusion The chemical and the heat treatment to treat the middle and late NSCLC,the patients completly support (bear). The recent treatment effect is better than the single chemical effect. Especially the effect of the glandular cancer is the best by using the heat treatment.

Objective To explore the repair result of full-thickness cartilage defects in diannan small-ear pig by bone mesenchymal stem cells (BMSCs) transferred with both transforming growth factor-β3(TGF-β3) and bone morphogenetic protein-2(BMP-2) gene mediated by adenovirus vector and combined with deminerized bone matrix (DBM). Methods 32 full-thickness defects from 16 knees of 8 pigs were randomly divided into 4 groups in the experiments. In group A, the animals′ lateral femoral condyle of right knee joint was repaired with DBM and BMSC infected with both Ad-TGF-β3 and Ad-BMP-2. In group B, the medial femoral condyle of right knee joint was repaired with DBM and BMSC without infection. In group C, the lateral femoral condyle of left knee joint was repaired with DBM. And the group D is control group. Morphology and histology were observed 2, 4, 8 and 12 weeks after operation. Results 12 weeks after operation, the whole defects were repaired in group A, HE staining showed typical cartilaginous structure in the repaired area. In group D, defects were not repaired but filled with fibrous tissue. The O′driscoll scores were 15.65 ± 0.11 (group A), 11.33 ± 0.22 (group B), 6.13 ± 0.15 (group C) and 5.08 ± 0.15 (group D). There was significant difference among the groups (P < 0.05). Conclusions The new type of tissue engineering scaffold that DBM combined with BMSCs transfected with both Ad-BMP-2 and Ad-TGF-β3 could induce cartilage regeneration and repair the defects.

BACKGROUND: Demineralized bone matrix (DBM) has natural mesh pores, good plasticity and biocompatibility. However, the decalcification time in preparation of DBM remains controversial.OBJECTIVE: To compare effects of varying degrees of decalcification with DBM on the proliferation of bone marrow stromal stem cells (BMSCs) so as to provide the best DBM scaffold for cartilage tissue engineeringMETHODS: Rabbit iliac bones were prepared into strips, defatted, followed by 6,12 and 24 hours of decalcification and 2 days of soaking in alcohol to prepare DBM. DBMs were placed in 24-well plates. The third passage of BMSCs at a density of 5×10~9/L were incubated on 24-well plate with DBMs. The DBM porosity and pore size were observed by scanning electron microscopy;BMSCs proliferation on the DBM was determined by MTT, and cell attachment on DBM was observed by scanning electron microscopy.RESULTS AND CONCLUSION: DBM displayed natural high-density porous grid structure, in the presence of bone trabecula,trabecular space and bone luminal system. The porosity and pore size of DBM decalcified for 6,12 and 24 hours were similar (P > 0.05). Compared with decalcified for 12 and 24 hours, BMSCs attached to DBM decalcified for 6 hours more closely and the DBM showed better compatibility. SEM observation showed the BMSCs on DBMs decalcified for 6 hours proliferated stably after 8 days and applicable for transplantation. Moreover, the number of cells were significantly more than DBMs decalcified for 12 and24 hours (P< 0.01).

BACKGROUND: Demineralized bone matrix (DBM) having a great biocompatibility is a common material to repair bone defect in clinic Bone marrow stromal cells (BMSCs) which can differentiate into bone and cartilage cells are ideal for repairing cartilage defect. OBJECTIVE: To observe the effects of allograft DBM combined with autograft BMSCs on repairing the articular cartilage of rabbits. METHODS: Bone and cartilage defect was induced in 27 rabbits and the models were randomly divided into combined group (DBM combined with 8-day-curtured autograft BMSCs), DBM group (DBM implantation alone), and control group. The reparative tissue samples were evaluated grossly, histologically, and immunohistochemically. The repairing effect was evaluated by Wakitani's score system.RESULTS AND CONCLUSION: The repaired tissues were hyaline cartilage-shaped, smooth and glossy, and well combined with peripheral cartilage and subchondral tissues at 12 weeks after implantation in the combined group; some tissues were cartilage-likely repaired in the DBM group; a few of tissues were fiber-like repaired in the control group. Immunohistochemical staining showed that type Ⅱ collagen was positive in both combined and DBM groups. Repaired cells which could express type Ⅱ collagen were cartilage cells. However, the expression of type Ⅱ collagen was negative in the control group. At 4,8, and 12 weeks after implantation, the scores in the combined group were significantly higher than in the DBM and control groups (P < 0.01), suggesting that DBM/BMSCs complex could be an efficient graft to repair the articular cartilage defects.

Objective To explore the risk factors of lung cancer in non-smoking Chinese women and to provide evidence for lung cancer prevention and control.Methods Information was collected on case-control studies published in the journals,both nationally and internationally from January,1995 to November,2014 that reported correlations between lung cancer and risk factors.Pooled odds ratio (OR) and 95％ confidence interval (CI) of risk factors on lung cancer in non-smoking Chinese women were calculated,using the Meta-analysis method,with sensitivity and publication bias tested.Results Information on 24 case-control studies was selected including 11 946 cumulative cases and 12 596 controls.Pooled ORs (95％CI) were shown as:history of lung diseases 1.89 (1.57,2.27),history of tuberculosis 1.86 (1.53,2.27),history of chronic bronchitis 1.51 (1.04,2.19),family history of cancers 2.02 (1.67,2.44),family history of lung cancers 2.45 (1.80,3.34),passive smoking (at workplace in adult period 1.47 (1.28,1.69),at home in adulthood 1.22 (1.09,1.36),in all life's time 1.52 (1.29,1.79),kitchen smog while cooking 2.21 (1.27,2.96),position of kitchen 1.76 (1.48,2.09),and frequency of deep frying per week 2.24 (1.61,3.12) etc.respectively.Conclusion Major risk factors related to lung cancer in non-smoking Chinese women would include lung diseases,family history of cancers,and passive smoking (tobacco smog and cooking smog).Particularly,the combination of family history and the degree of cooking presented stronger correlation effects,indicating that genetic and environmental factors jointly played an important role in the development of lung cancer.

The incidence of prostate cancer is increasing year by year in China. People with BRCA mutation are at high risk of prostate cancer. However, there is no clear and effective treatment for mHSPC with high metastatic load carrying BRCA mutation. In this study, we report a mHSPC patient with high metastatic burden and germline BRCA1 gene mutation who rapidly progressed to mCRPC after traditional CAB therapy and then received ADT combined with abiraterone and achieved significant PSA response, suggesting that ADT combined with abiraterone may be an effective therapy for mHSPC patients with BRCA1 germline mutation.
