Study on relationship between Th1/Th2 cells/cell cytokines and tuberculosis pleural effusion adhesion / 实用医学杂志

Objective To investigate the relationship between cellular immune response which is related with Th1/Th2 cells and the different severities of tuberculosis pleural effusion adhesion.Methods A total of 66 in-patients diagnosed with different severities of tuberculosis pleural effusion adhesion by internal thoracoscope were enrolled from August 2014 to December 2016.ELISA was used to determine levels of INF-γ,TNF-α,IL-2 and IL-4. The ratio of Th1 and Th2 cells was detected by flow cytometry. Results All the patients were divided into 3 groups:9 cases without pleural adhesion,32 cases with mild pleural adhesion,25 cases with severe pleural adhe-sion. The levels of 4 cytokines in pleural fluid were significantly higher than those in serum in each group(P <0.05,respectively).The concentrations of INF-γ and TNF-α were increased with the severity of tuberculosis pleu-ral effusion adhesion. The levels of INF-γ and TNF-α in the severe pleural adhesion group were markedly higher than those in the other two groups(P<0.05,respectively).The proportion of Th1 cells in the severe pleural adhe-sion group was significantly higher than that in the none pleural adhesion group and in the mild pleural adhesion group(P<0.05,respectively).Conclusions The proportion of Th1 cells and levels of INF-γ and TNF-α are pos-itively related with pleural adhesion severity. Cellular immune response which is related with Th1 cells contributes to pathological immune pleural damage and intensify the severity of pleural adhesions.

Awaken Effect of Naloxon in Dexmedetomidine-Anesthetized Mice / 天津医药

Objective To investigate the awaken effect of naloxon on dexmedetomidine anesthetized mice and its mechanism. Methods Thirty Kunming mice of clean grade were randomly divided into 3 groups which included NAL group (Naloxon group), ATI group(Atipamezole group)and NS group (Normal Saline group). All groups were given dexme?detomidine 1 mg·kg-1 intraperitoneally. Naloxon 2 mg·kg-1, atipamezole 2 mg·kg-1 and normal saline 10 mL·kg-1 were ran?domly given intraperitoneally to the NAL, ATI and NS group respectively 90 minutes after dexmedetomidine administration. At timepoints prior to dexmedetomidine administration and 5, 15, 30, 60, 90, 95, 105, 120, 180 minutes after it, the sedative and analgesic effects besides recovery time (based on restore of righting reflex loss) were assessed. Results Sedation and analgesia effects became apparent within 5 minutes, and peaked at approximately 60 minutes then spontaneously recovered at 180 minutes after injection of dexmedetomidine. The sedative and analgesic effects were reduced in both ATI and NAL groups. Compared with ATI group, the sedation scores were higher at 95, 105 and 120 minutes after dexmedetomidine admin?istration than those in NAL group (P0.05). The analgesic scores were not statistically significant at time points of 95, 105, 120 and 180 min?utes between NAL group and ATI group, but they were lower in NAL group compared with NS group at timepoints of 95, 105 and 120 minutes (P>0.05). The recovery time in ATI and NAL group were shorter than that in NS group (F=1 793.368, P0.05). Conclusion Naloxone had a certain awaken effect on dexmedetomidine anesthetized mice.

Expression profile of apoptosis pathway-specific genes of prostate cancer cells and different apoptosis susceptibility / 中华泌尿外科杂志

Objective To determine whether altered expression of apoptosis pathway genes is related to different apoptosis susceptibility of prostate cancer cells. Methods Androgen sensitive and insensitive prostate cancer cell lines LNCaP and PC 3 were cultured and treated by etoposide,and apoptosis were determined using Hoechst 33258 staining.The cells were harvested and the total RNA was extracted.cDNA probes were prepared and labeled with biotin 16 dUTP,then hybridized to commercially available cDNA arrays including apoptosis pathway specific genes. Results Apoptosis were induced in both PC 3 and LNCaP cells by etoposide,however,PC 3 was more resistant than LNCaP.Compared with LNCaP cells,the 4 fold down regulated genes in PC 3 cells were Bcl10,CIDE A,GADD45a,RIP2,caspase 4,5 and 6,while the 4 fold up regulated gene in PC 3 cells was TRAF4.Caspase 14 and TNFR2 were most strongly expressed genes in the 2 cell lines. Conclusions The altered expressions of apoptosis pathway specific genes are related to the different apoptosis susceptibility,and this may make an important contribution to androgen insensitive state of prostate cancer cells.
