ABSTRACT

Objective To investigate the clinical value of preoperative lymphocyte-to-monocyte ratio(LMR)in evaluating the prognosis of patients with stage T1 non-muscle invasive bladder cancer(NMIBC).Methods A total of 215 patients with stage T1 NMIBC who underwent transurethral resection of bladder tumor were enrolled.Clinical data were collected.Patients were followed up and their disease-free survival(DFS)and overall survival(OS)were recorded.The receiver operating characteristic(ROC)curve of preoperative LMR in detecting patient prognosis was used to determine the optimal cut-off value for LMR.Patients were divided into low LMR group(LMR <3.86,=77)and high LMR group(LMR ≥ 3.86,=138).Kaplan-Meier survival curves were explored to compare cumulative DFS and OS rates in patients with different LMR levels,and COX proportional hazards regression model was used to analyze factors associated with DFS and OS.Results All these 215 patients with T1 stage NMIBC were followed up for 2-92 months,and the DFS rate was 59.07% and OS rate was 65.12%.Kaplan-Meier curves showed that the cumulative DFS rate(=4.784,=0.029)and cumulative OS rate(=7.146, =0.008)in the low LMR group were significantly lower than those in the high LMR group.Tumor size ≥ 3 cm(=1.398,95% :1.042-1.875,=0.025),pathological grade G3(=1.266,95% :1.026-1.563,=0.028),and LMR ≥ 3.86(=2.347,95% :1.080-5.101,=0.031)were independent factors associated with DFS in patients with stage T NMIBC.In addition,tumor size ≥ 3 cm(=1.228,95% :1.015-1.484,=0.034),pathological grade G3(=1.366,95% :1.017-1.834,=0.038),and LMR<3.86(=2.008,95% :1.052-3.832,=0.035)were independent factors associated with OS in patients with T1 stage NMIBC. Conclusion Preoperative LMR is an independent factor associated with patients' prognosis in T1 stage NIMBC.Patients with low LMR tend to have higher risk of NMIBC progression and death.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect and possible mechanism of bromo-domain inhibitors (JQ1) on proliferation inhibition and inducing apoptosis of acute T lymphocyte leukemia cell line (Jurkat) .</p><p><b>METHODS</b>Jurkat cell line was treated by JQ1 at different concentrations. MTT was used to detect the cell proliferation inhibition rate. The flow cytometry with AnnexinV-FITC/PI fluorescence staining was used to detect the changes of apoptosis rate, and real-time fluorescent quantitative PCR was used to detect c-Myc/Notch1 gene expression levels.</p><p><b>RESULTS</b>With the increasing of drug concentration and prolonging of time, the inhibitory rate of Jurkat cell growth was enhanced in time-dose dependent manner; Jurkat cells was treated by 0.8, 1.6, and 4 µ mol/LJQ1 for 48 h and 72 h, the cell apoptosis rate was enhanced with the increase of drug concentration and prolonging of time, and the difference was statistically different in comparison with the control group(P<0.05); PCR detection indicated that Notch1 and c-Myc mRNA expression was reduced in 48 h after JQ1 treatment, which was statistically different from the control group,(P<0.05) .</p><p><b>CONCLUSION</b>JQ1 can effectively inhibit the growth of Jurkat cell line, and potentially induce apoptosis through Notch1 and c-Myc gene. Hence JQ1 may be one of new methods used to treat T-ALL.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of five kinds of fertilizers at three application levels on the content of 2-undecanone and carbohydrate in Houttuynia cordata.</p><p><b>METHOD</b>A single factor randomized block design was used to investigate the content of 2-undecanone and carbohydrate in the plant.</p><p><b>RESULT</b>The results showed that the content of 2-undecanone was the highest both in aerial and underground parts of H. cordata, which was fertilized with complex fertilizers served in conventional way, having the content 18.6 microg g(-1) and 26.0 microg g(-1) respectively. In addition, 2-undecanone contents in aerial parts of H. cordata (14.9 microg g(-1)) fertilized with manure of human were also higher than that with chemical fertilizer, pig and duck manures, but no significant difference were found among the other treatments in aerial or underground parts of the plants, respectively. The results also demonstrated that fertilized with organic fertilizer might be beneficial to enhance the quality of sugar in H. cordata, mainly including the contents of total sugar, solutable sugar, fructose and reduced sugar in the plants, especially with manure of human and pig.</p><p><b>CONCLUSION</b>As the result of this study and the related previous research on yield of H. cordata were considered, the fertilizing ways for increasing quality of H. cordata should take the manure of human as a main fertilizer and mix with the other organic fertilizers, complex fertilizers and chemical ones may be needed to balance the plant nutrient. In the field practice, the amount of organic fertilizer including 108,000 kg hm(-2) human mature, together with some high-efficient complex fertilizer and a small amount of quick-acting chemical fertilizer is recommended.</p>

ABSTRACT

<p><b>AIM</b>To observe the property alteration of K(v) channel in SLE patient's peripheral blood lymphocyte and its significant.</p><p><b>METHODS</b>The patch-clamp technique was used to record the current of K(V) channel in SLE patient's peripheral lymphocyte.</p><p><b>RESULTS</b>The current amplitude of K(V) channel in the SLE patient's lymphocytes decreased, it was (258.6 +/- 112.5) pA in healthy people, but in SLE patient it was (139.4 +/- 58.5) pA (P < 0.05). There was no other changes in the property of channel, include activation potential, inactivation property, channel closing kinetics and its pharmacological property.</p><p><b>CONCLUSION</b>The decline of SLE patient's cell immunity may be related to the decrease of the amplitude of K(V) channel current.</p>
