Brain metastasis is among the most common complications of non-small celllung cancer (NSCLC) and may obviously influence the survival and quality of life in the NSCLC patients. Recently, the development in traditional treatments, the widely-used micro-molecular targeted drugs, and the combined treatment have improved the overall survival and the quality of life of these patients. In addition, the exploration of new therapeutic targets and cognitive function protective methods for current treatments also deserves at-tention. This review emphasizes the relevant clinical and basic problems and the therapeutic strategies in NSCLC with brain metastases.

[ABSTRACT]OBJECTIVETo investigate the cytomegalovirus infection in neonates, characteristics of gap junction protein Connexin26 gene mutation and the hearing follow-up results, and to analyze their correlations. METHODS60 CMV-DNA positive and 40 CMV-DNA negative neonatal newborn from The Second Affiliated Hospital of Wenzhou Medical University and The first people's Hospital of Yongkang were screened, the blood biochemistry was analyzed, and the umbilical cord blood was reserved to detect the Connexin26 gene expression of mRNA with RT-PCR.PCR results was sequenced to track the newborn hearing, and analyze the correlations between neonatal cytomegalovirus types, the mutation of Connexin26 gene and hearing test results.RESULTS 26 cases from 60 CMV-DNA positive newborns were found with blood biochemical abnormalities. In all of the newborns, a total of 41 cases had 235delC mutation, 11 cases in the mutations for the development of hearing impairment. The results of correlation analysis showed that there were correlations between cytomegalovirus infection, gene mutation and hearing impairment.CONCLUSION Cytomegalovirus infection in neonates can lead to mutations in the Connexin26 gene, and may further lead to hearing impairment, and the probability of the mutation of Connexin26 gene and sensorineural hearing loss were higher in symptomatic cytomegalovirus infection neonates.

Objective To study human bocavirus (HBoV) induced respiratory tract infection in Guangdong Province in China. Methods HBoV was deteced by using polymerase chain reaction (PCR) technology and was identified by DNA sequences. Results One strain of HBoV was detected and identified from 50 samples collected from children with acute respiratory tract infections. This was the first clinical case of HBoV infection reported in Guangdong and was named as GD-1 strain. The HBoV capsid protein (VP) gene amplified from the specimen by PCR was identified by sequencing and was compared with gene sequences in GenBank. Phylogenetic trees were constructed for sequence homology analysis. The nucleotides similarities between GD-1 and Beijing strains, France strains and Canada strains were over 98%, while the simlilarity was over 36% compared with Korea KNIH-2K6GJ2713 strain and over 77% compared with US NH4549 strain. Conclusion HBoV infection does exist in Guangdong Province. It is valuable to start systemic study on it.

Objective To understand psychiatry hospital nurse' s self-compassion situation, explore the influencing factors, for nursing managers to know about the clinical nurses psychological health and to provide a reference data of intervention to improve the level of self-compassion. Methods A total of 381 clinical nurses from the Affiliated Brain Hospital of Guangzhou Medical University (Guangzhou Huiai Hospital) completed the survey using the questionnaire including the Self-Compassion Scale (SCS) and general information questionnaire. The influence factors were analyzed by chi-square test and Logistic regression analysis. Results The total score of SCS was (85.43 ± 10.23) points in 381 clinical nurses with the medium level, which was less than that of other nurse group (109.21±9.76) points, and there was significant difference(t=-45.388, P < 0.01).The Logistic regression analysis showed that female and working in the psychiatric ward were the risk factors of self compassion(OR=1.772, 1.995, P<0.05 or 0.01). While on the night shift was the protective factor(OR=0.536, P < 0.01). Conclusions Psychiatric hospital nurse' s self-compassion is at medium level. When the nurses cope with the negative events may lack adjustment method. Nursing managers should pay attention to train the ability of the nurse individual self-compassion, targeted to carry out active intervention measures.
