Urothelial carcinoma associated antigen 1(UCA1)is a highly bladder cancer-specific long non-coding RNA(lncRNA),and it does not have the function of encoding protein. UCA1 differentially expre-sses in various fetal tissues,but its expression is turned off in most adult tissues. It reactivates during tumori-genesis. Researches indicate that UCA1 may regulate cell proliferation,apoptosis,metastasis and chemoresis-tance of tumors,such as bladder cancer,breast cancer and hepatocellular cancer.

Long non-coding RNA (lncRNA)is a kind of RNA molecule which is longer than 200 nucleotides and has no capacity of coding proteins.Accumulating evidences have indicated that several lncRNAs,such as HOTAIR,MALAT-1 ,H1 9 and BANCR may promote tumor metastasis by inducing epitheli-al-mesenchymal transition.

Objective To compare the effects of mild hypothermia or normothermia on inflammatory cytokines (IL-2 and IL-10) in elderly patients undergoing surgery for rectal cancer, and determine whether the elevation of IL-2 and IL-10 levels and early postoperative cognitive dysfunction has the relevant. Methods Forty ASA classification Ⅰ or Ⅱ patients aged 65-83 yr undergoing surgery for rectal cancer were randomly divided into 2 groups (n=20 each):normal body temperature group (GroupⅠ) and mild hypothermia group (GroupⅡ) . The venous blood samples were taken at 3 points which were at 1 h before anesthesia (T1), the end of operation (T2) and the 24h after operation (T3) to measure the levels of plasma IL-2 and IL-10. The cognitive function test (MMSE) were performed at one day before operation (N1), one day after operation (N2) and 3th days after operation (N3) . Results The level of plasma IL-2 was significantly lower in the GroupⅡthan that in the GroupⅠat T2 and T3 ( < 0.01), and those was significantly lower at T3 than that at T2 ( <0.01) . The level of plasma IL-10 was significantly higher in the GroupⅡat T3 than that at T1 and T2 ( <0.01) . To compare with N1, the score of both groups were decreased at N2 ( <0.05), and it was lower in GroupⅡthan that in GroupⅠ( <0.05), with a significant difference. The score of both groups were increased significantly at N3 (<0.05), and there was significant difference with N2 ( <0.05);Positive correlation was found between IL-2 at T2 and T3 and the score of MMSE in the GroupⅡat N2 ( =0.459, <0.01) ( =0.550, <0.01) . Conclusion Positive correlations were found between the elevation of IL-2 levels under mild hypothermia and the decline of postoperative early cognitive function in elderly undergoing rectal cancer surgery.

Objective To investigate the effects of mild pefioperative hypothermia on cellular immune function in patients undergoing surgery for rectal cancer.Methods Fifty ASA Ⅰ or Ⅱ patients aged 30-64 yr undergoing surgery for rectal cancer were randomly divided into 2 groups ( n =25 each):mild hypothermia group and normal body temperature group.Anesthesia was induced with midazolam,fentanyl,etomidate and vecuronium and maintained with propofol,remifentanil and vecuronium.The patients were mechanically ventilated after tracheal intubation.PET CO2 was maintained at 35-45 mm Hg.The venous blood samples were taken from peripheral vein at 1 h before anesthesia (T1 ),at the end of operation (T2),at 24 h after operation (T3),and on 7th day after operation (T4) to measure the serum Th1 and Th2 cytokines levels and Th1/Th2 cytokines balance was observed.Results Compared with the baseline value at T1,the serum Th2 cytokines level was significantly decreased and Th1/Th2 ratio was significantly increased at T4 in normal body temperature group,and the serum Th1 cytokines level and Th1/Th2 ratio were significantly decreased and the serum Th2 cytokines level was significantly increased at T2.3 in mild hypothermia group ( P ＜ 0.05).Compared with normal body temperature group,the serum Th1 cytokines level and Th1/Th2 ratio were significantly decreased and the serum Th2 cytokines level was significantly increased at T2-4 in mild hypothermia group ( P ＜ 0.05).Conclusion Mild perioperative hypothermia can depress cellular immune function in patients undergoing surgery for rectal cancer.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

Objective:This study investigated the prognostic significance of age at diagnosis, stage, tumor subtype, pelvic lymph node metastasis (PLNM), lymph-vascular space involvement (LVSI), presence or absence of deep cervical stromal invasion (DCSI) in stage ⅠB-ⅡA cervical cancer patients. It also investigated the inter-relationship among these factors. Methods: 152 patients treated with radical hysterectomy plus pelvic lymphadenectomy were followed up for a median of 49 months and were evaluated retrospectively. Results: The 5-year overall survival rate was 84.8%. The distribution of age at diagnosis is of bimodal shape, peaking at 42 and 68 years, respectively. Tumor subtype, PLNM, DCSI, and LVSI were found to be significant prognostic factors individually. After multivariate analysis, only tumor subtype and PLNM were found to be independent, significant prognostic factors for survival. The prognostic importance of LVSI appeared to be eclipsed by the presence of PLNM. DCSI was statistically related with FIGO stage, LVSI and PLNM. Conclusion: Tumor subtype and PLNM are the two most important independent prognostic factors for stages ⅠB-ⅡA cervical cancer. Some prognostic factors are inter-related and may reflect different facets of tumor progression.

Objective To establish an ELISA to detect the concentration of apo A-V in human plasma and evaluate the sensitivity and stability of the method.Methods The standard curve of recombinant human apo A-V, the lowest detectable concentration, the day-to-day variation and between-plate-within-day variation, the interference of other non-specialized apolipoprotein were examined, and the reference range was established by detecting the plasma concentration of apo A-V in 505 healthy subjects.Results The linear range of the established method was 5.86 - 187.5 ng/ml with lowest detectable concentration of 2.34 ng/ml. The interferences for apo A-V detection due to Lp(a), apo AI and apo B was never found in our study. The day-to-day variation and between-plate-within-day variation were less than 10% respectively.Conclusion An ELISA for detecting the concentration of apo A-V in human plasma was established and the method can serve as a useful tool for research on mechanism and function of apo A-V in TG metabolism.

Purpose To investigate the effect of tolerogenic dendritic cells ( DC) on T lymphocytes in the spleen during the develop-ment of zymosan-induced sepsis in mice, and to explore whether PD-L1 blockade could alleviate the immunosuppressive effect of tolero-genic DC on T lymphocytes. Methods Mice sepsis model was established by intraperitoneal injection of zymosan. Splenic DC and T lymphocytes were isolated respectively by using anti-CD11c and anti-CD3 magnetic beads. The expressions of PD-L1, PD-1 and PIR-B on splenic DC were measured, and IL-12 and IL-10 secreted from DC were determined. Mitogen-induced T lymphocyte proliferation and IL-2 secretion were assessed. Anti- PD-L1 antibody was added into mixed culture of tolerogenic DCs with normal Tcells. T cell proliferation and IL-2, IL-12 and IL-10 concentrations in the supernatant of mixed culture were determined. Results At 5 days and 12 days after zymosan injection, the expressions of PD-L1, PD-1 and PIR-B on splenic DC increased greatly, secretion of IL-12p70 re-duced and that of IL-12p40 and IL-10 augmented in DC, which were associated with decrease of T cells proliferation and IL-2 secre-tion. Administrating anti-PD-L1 antibody into the mixed culture of tolerogenic DC and Tcell could alleviate the suppression of DC on T lymphocyte proliferation and secretion of IL-2, and ameliorate the ability of DC secreting IL-12 and IL-10 as well. Conclusions At late stage of zymosan-induced sepsis, the formation of splenic tolerogenic DC resulted in immunosuppression of T lymphocytes. Anti-PD-L1 antibody could improve the immunoactivity of DC and T lymphocyte through intervening PD-L1/PD-1 pathway.
