The inhibition of pulmonary metastasis by inhalation of aerosolized recombinant 1L-2 (rIL-2) in BCG-primed mice is reported in this paper . (TA2 x 615) Fl mice were given ip BCG twice in two-week apart.Right after the second BCG injection, MA891 cells, a murine mammary adenocarcinoma of TA2 origin, were injected into the tail vein.Treatment with aerosolized rIL -2 by inhalation was given for 1 hr, 3 times a day and lasted for 14 days. After sacrifice, bronchoalveolar lavage was performed and the lavage fluid was examined for nitric oxide content. The number of tumor nodules on the lung surface was recorded as a measure of the extent of pulmonary metastasis. The results showed that in mice so treated, pulmonary metastasis was very significantly inhibited. When rIL-2 treatment was given in BCG-unprimed mice, inhibition of pulmonary metastasis was also observed albeit to a much lesser extent. Significant inhibition of lung metastasis was associated with significant increase in nitric oxide content in the broncho-alveolar lavage fluid. Moreover, when nitric oxide synthase inhibitor, NG monomethyl-L-arginine (7mg/kg) was given ip shortly before each inhalation of rIL-2, accompanied with a significant reduction of nitric oxide in the lavage fluid, the inhibitory effect of rIL-2 in both BCG-primed and -unprimed mice was almost completely abrogated. Taken together, the results clearly indicate that pulmonary metastasis can be effectively treated by the induction of endogenous release of nitric oxide from activated alveolar macrophages.

Objective To study the rehabilitation effects of the cochlear implants on prelingually deaf children with alba abnormality.Methods A retrospective analysis of the effects of CIs was conducted in the prelingually deaf children of 11 cases of the children with abnormal alba(the research group) and 18 cases of the children who had normal alba(the control group) at the First Affiliated Hospital of Fujian medical university.All the operations were completed by the same doctor.There were no obvious complications during and after the operation.The cochlear implants were turned on after one month and the prelingually deaf children with extremely severe bilateral sensorineural deafness were trained for speech at the rehabilitation centre.The assessment criteria of the categories of auditory performance(CAP) and speech intelligibility rate(SIR) were used.After six months and twelve months of the operation, the family members were followed who have direct contacts with the children.The evaluation of data between the research and the control groups was administered.Results In the research group, the average level of CAP after six months'' post-operation was 2.41±0.47.But in the control group, the average level was 3.28±0.45.In the research group, the average level of SIR after six months'' post-operation was 1.27±0.44.There were 3 children in the research group at level 2, but in the control group, the average level was 1.89±0.31.Two children in the control group were level 1 while the others were level 2.In the research group, the average level of CAP after twelve months'' post-operation was 4.00±0.43 while only one child at level 3.There was one child at level 5 in the research group, the rest were level 4.There was a statistically significant difference in the average level of the CAP after six months'' post-operation(t=4.983, P<0.05) and in the average level of the SIR after six months'' post-operation(t=4.371, P<0.05).There was no statistical difference in the average level of the CAP after twelve months'' post-operation(t=1.033, P>0.05) and in the average level of the SIR after twelve months'' post-operation(t=0.434, P>0.05).Conclusion There is no significant difference of the rehabilitation effects of post-operation between the prelingually deaf children with alba abnormality and those with normal alba.

Objective To investigate the expression of Beclin1,p62 and Atg5 in serous ovarian cancer and its clinical significance.Methods The expression of Beclin1,p62 and Atg5 was detected in 50 serous ovarian cancer tissues by immunohistochemical method,and the relationship between their expression levels and the clinical parameters of serous ovarian cancer patients were analyzed.Results The expression of Beclin1 and Atg5 in serous ovarian cancer tissue was significantly lower than that in normal ovarian tissue,but p62 was significantly higher than that in normal ovarian tissue,and the difference had statistically significance (P＜0.05).The expression of Beclin1 and Atg5 were correlated with degree of cell differentiation and clinical stage (P＜0.05),while the expression of p62 was associated with clinical stages and lymph node metastasis (P＜0.05).Conclusions The abnormal expression of Beclin1,p62,Atg5 in serous ovarian cancer,which can lead to reduced autophagy body formation and autophagy activity,may be involved in the occurrence and development of serous ovarian cancer.

BACKGROUND:Neural stem cel transplantation provides an important way to treat sequela of traumatic brain injury, but the timing for treatment is inconclusive.
OBJECTIVE:To explore the clinical effect of neural stem cel transplantation in the treatment of sequela of traumatic brain injury and the choice of the best treatment time.
METHODS: Totaly 178 patients with sequela of traumatic brain injury who underwent neural stem cel transplantation were divided into three groups as per the timing for neural stem cel transplantation: group A (with 6 months after injury,n=60), group B (6-12 months after injury,n=59), and group C (over 12 months after injury,n=59). Improvement in clinical symptoms and scores on function independent measure (FIM) were recorded and compared in the three groups.
RESULTS AND CONCLUSION:The total effective rate of group A was significantly higher than that in groups B and C (P < 0.05). FIM scores were significantly improved in the three groups after cel transplantation (P < 0.05). At 3 months after the fourth transplantation, the FIM score in the group A was significantly higher than that in the other two groups, and the incidence of adverse reactions in the group A was significantly lower than that in the other two groups (P < 0.05). These findings indicate that neural stem cel transplantation at different timing can al harvest certain clinical effects, but the best timing for neural stem cel transplantation is within 6 months after injury.
