Objective To preliminary study clinical efficacy and toxicity of endostatin (ES) combined radiotherapy and chemotherapy in advanced non-small cell lung cancer (NSCLC),and evaluate its effectiveness and safety.Methods We retrospectively reviewed 64 patients with Ⅲ B-Ⅳ stage NSCLC of Harbin Medical University Cancer Hospital from February 2009 to February 2012.The patients were divided into two groups:chemoradiotherapy group,39 patients and ES add chemoradiotherapy group,25 patients.The short-term effect,the total efficiency,median survival time,progression-free survival time and disease-free survival time were compared.Results The total effective rate of chemoradiotherapy group was 76.9％,while the total effective rate of ES add chemotherapy group was 84.0％ (x2 =0.47,P =0.492).Chemoradiotherapy group,compared to ES add chemotherapy group,the median survival time,median progression-free survival time,median disease-free survival time were 11.52 months vs 16.51 months (x2 =3.74,P =0.042),7.32 months vs 10.37 months (x2 =5.32,P =0.025) and 5.21 months vs 7.57 months (x2 =4.56,P =0.035) respectively.The mainly adverse drug reactions were hematologic toxicity and gastrointestinal reactions,but there were no significant differences between the two groups; radiotherapy side effects mainly showed the grade 1 to 2 radiationinduced lung injury and radiation esophagitis (chemotherapy group had one case of grade 3 radiation-induced lung injury),but also had no significant differences between the two groups.Conclusion ES combined chemoradiotherapy can achieve a better short-term clinical efficacy without increasing adverse effects of radiotherapy or chemotherapy in advanced non-small cell lung cancer.

Epidemiological and clinical studies have provided compelling evidence that suggests a link between the relative lack of infectious diseases and the increase in allergic disorders. Asthma usually starts early in life. The early occurrence of asthma suggests that prinatal influences are of importance.Prenatal or postnatal exposure to endotoxins and other bacterial products may protect against the development of asthma in the infant. We will briefly outline the current state of the relationship of the perinatal infection and asthma in the infant, and focus our review mainly on possible rneehanism of perinatal infection providing protection against asthma in the infant, such as Th1/Th2 immune system, transcription factors, protection by maternal antibodies, endotoxin tolerance, pulmonary inflammation and genetic influences.

Objective To investigate the relationship between C-reactive protein (CRP) and postoperative cognitive function of female patients underwent cardiopulmonary bypass (CPB) cardiac surgery.Methods Sixty female patients were scheduled for CPB surgery from January 2012 to May 2013,aged form 35 to 60 years,mean aged (47.5 ± 12.5) years,and in state of ASAⅡ ～ Ⅲ.All patients had general anesthesia and CPB cardiac surgery.Blood samples were taken from peripheral vein before induction and 6 days after surgery.The neuropsychology assessment was measured with Wechsler Adult Intelligence Scale RC 2 + 1 (WAIS-RC) and digital span the first day preoperative,the 7th day,and the first month postoperative.The postoperative cognitive dysfunction (POCD) was judged with Newman style.Results (1) The rate of POCD of the 7th day and first month postoperatively was 50％ and 25％,respectively.(2) The Pearsong correlation showed negative correlation between CRP preoperative at the 6th day and the 7th day,and the first month postoperative WAIS-RC score(P ＜ 0.05).(3) The Pearson's figure showed negative correlation between CRP at the 6th day postoperative with digital span (P ＜ 0.05).Conclusions The ratio of POCD after CPB surgery was higher.It is instructively significant to monitor the variations of concentration of serum CRP for the selection of cognitive impairment in patients with cardiac-pulmonary bypass surgery.

Objective To investigate the interactions between melanoma-derived exosomes and the microenvironment.Methods The exosomes were isolated from the culture medium of mouse melanoma cells and then co-cuhured with mesenchymal stromal cells (MSC) after identification.Immunofluorescence assay was performed to observe the exosomes engulfed by MSC.CCK-8 and transwell assays were used to evaluate the proliferation and migration of MSC.Effects of the exosomes on the expression of α-smooth muscle actin (α-SMA) in MSC were analyzed by Western blot.Results Co-culture of MSC with melanoma cell-derived exosomes enhanced the proliferation and migration of MSC as well as the expression of α-SMA.All of the changes mediated by the exosomes could be blocked by using the inhibitor of TGF-β receptor.Conclusion Melanoma cell-derived exosomes enhanced the proliferation and migration of MSC as well as the expression of α-SMA through TGF-β signaling pathway,which provided an advantageous microenvironment for melanoma progression.

A novel built-in-self-test (BIST) method called seeded autonomous cyclic shift register (SACSR) is presented to reduce test power of the sequential circuit. The key idea is to use a pseudorandom pattern generator and several XOR gates to generate seeds that share fewer test vectors. The generated seed is taken XOR operation with a cyclic shift register, and the single input change (SIC) sequence is generated. The proposed scheme is easily implemented and can reduce the switching activities of the circuit under test (CUT) greatly. Experimental results on ISCAS89 benchmarks show that on average more than 63% power reduction can be achieved. It also demonstrates that the generated test vectors attain high fault coverage for stuck-at fault and transition fault coverage with short test length.
