1.EXPERIENCES IN RE -OPERATION OF LIVER RESECTION OF PRIMARY LIVER CANCER
Academic Journal of Second Military Medical University 1982;0(01):-
From January, 1960 to April. 1983, 292 cases of primary liver cancer were treated by liver resection. Of them, 21 cases underwent re-exploratory operation for relapsed reason and 14 tumours were removed with a resectability rate of 66.7%.In this series recurred tumours in 3 patients were resected by a two-stage operation with hepatic artery ligation or embolizaton as the first step.Following-up results: 7 out of 14 resected cases survivors, 2 survived above one year, 4 more than half a year and 1 less than half a year; in another 7 cases died post-reoperativelly, 1 above one year, 4 more than half a year, 1 less than half a year.As for AFP detection 4 patients were negative and in 1 patient the AFP titre decreased to 100 ug/ml on the 33rd post-reoperative day. From the above data the authors believe that re-operation may be considered as a most effective method if it is performed at a proper time and radiotherapy, hepatic artery ligation or embolization are of great value in treating recurred cases. For the improvment of the surgical results of primary liver cancer,a preliminary scheme for investion and management procedure for such patients is suggested by the authors as well.

Chinese Journal of Practical Nursing 2017;33(21):1654-1658
Objective To investigate the status of personality, family function and psychological resilience towards employed nurses, and to explore the relationship among personality, family function and psychological resilience. Methods Four instruments were applied to investigate 240 employed nurses from comprehensive Grade 3A hospital of Fujian Province, which were the Characteristics Questionnaire, Family Intimacy Scale (FACEⅡ-CV), Self-resilience Scale and Personality Traits Questionnaire. Results The correlation analysis showed that nurses′ personality traits, family functions and psychological resilience were closely related. The multiple regression and analysis showed that 40%of the variance for employed nurses′psychological resilience could be explained through considering personality dimensions, family cohesion and adaptability. Conclusions Personality, family functions and psychological resilience towards employed nurses are closely related as both internal and external protective factors.
6.The role of TRPM7 ion channel in the proliferation and migration of oral squamous cancer cells
Journal of Practical Stomatology 2017;33(4):531-535
Objective:To investigate the role of the transient receptor potential melastatin subfamily member 7 (TRPM7) ion channel in the proliferation and migration of oral squamous cancer cells OC2.Methods:The expression of TRPM7 in OC2 cells was examined by western blotting,RT-PCR and indirect immunofluorescence assay.The influence of TRPM7 on cell proliferation and migration under the inhibition of TRPM7 ion channel with 2-APB or siRNA TRPM7 in OC2 cells was examined by MTT and Transwell respectively.The influence of PI3K/AKT signal pathway on the expression of TRPM7 in OC2 cells was tested by Western blotting.The change of positive ion current when the OC2 cells were treated with TRPM7 inhibitor and activator was explored with patch clamp technique.Results:TRPM7 overexpression in OC2 cells mainly in the cytoplasm was observed,siRNA TRPM7 downregulated the expression of TRPM7.Inhibition of TRPM7 (2-APB or siRNA TRPM7) inhibited the growth and proliferation of OC2 cells in a time-and dose-dependent manner.Blockage of TRPM7 ion channel inhibited the migration capacity of OC2 cells.Inhibition of TRPM7 downregulated the expression of phosphorylated AKT and phosphorylated ERK.Patch clamp assay showed the activation of TRPM7-like current in OC2 cells.2-APB could weaken this current while Bradykinin could enhance the current.Conclusion:TRPM7 may regulate the proliferation and migration of oral cancer cells by the regulation of PI3K/AKT and MAPK/ERK signal pathways and cell positive current.
