Objective To explore the curative effect of combined use of minimally invasive percutaneous nephrolithotomy (MPCNL) and extracorporeal shockwave lithotripsy (ESWL) for the treatment of solitary renal staghorn calculi in patients with renal insufficiency. Methods Eight cases of solitary renal staghorn calculi associated with renal insufficiency were treated by a combination of MPCNL and ESWL. Results Stones were completely cleared away in 5 cases, while residual stones were found in 3 cases. No blood transfusion was required and no severe surgery-related complications were encountered. After surgery variable degrees of improvement in renal functions was observed. The serum creatinine (Cr) decreased from 289?166 ?mol/L pre-operation to 155?33 ?mol/L post-operation (t=4.69, P=0.004), and the blood urea nitrogen (BUN) decreased from 15.1?7.9 mmol/L to 8.3?1.9 mmol/L (t=4.00, P=0.005). The emission computed tomography (ECT) examinations showed the glomerular filtration rate (GFR) was elevated from 48.8?12.4 ml/s before operation to 63.0?8.4 ml/s after operation (t=4.68, P=0.003). Post-renal obstruction disappeared after operation. Follow-up for 0.5~4.5 years (mean, 2.8 years) in the 8 cases revealed no obvious changes in renal functions. Conclusions Combination of MPCNL and ESWL for solitary renal staghorn calculi associated with renal insufficiency is safe and effective.

Objective To investigate the change of CD_4~+CD_(25)~(high)CD_(127)~(low)> regulatory T cells (Trcg cells) sub-group level in peripheral blood of non-Hodgkin lymphama (NHL) patients, and to explore its clinical significance. Methods Treg cells levels in peripheral blood of lymphoma patients and normal were detected by flow cytometry, followed by statistical analysis. Results In the 65 cases of NHL patients, Treg cells in peripheral blood were (6.72±1.38) %, higher than that in the normal control group (5.65±0.68) % (P <0.05). Percentage of Treg cells are significantly different between clinical stages and normal: [P <0.05, normal control group (5.65±0.88) %, Ⅰ -Ⅱ period (6.08±1.18) %, Ⅲ-Ⅳ period (6.95±0.85) %]. The percentage of Treg cells are also different among pathological types of patients and normal [P <0.05, normal control group (5.65± 0.68) %. The percentage of Treg diffuse large B-cell lymphoma (5.83±0.95) % and other subtypes of lymphoma (7.83±1.76) %]were observed. It is not sure that Treg cells percentage among patients with different levels of lactate dehydrogenase and normal are significantly different. [P >0.05, normal control group (5.65±0.68) %, patients with normal LDH group (6.97±1.20) %, patients with lactate dehydrogenase (6.54±1.02) %]. Conclusion Treg cells induced by tumor and could inhibit the immune cells, Treg cells percentage in peripheral blood of tumor patients is higher than that the normal control group, and increased with the clinical staging, so the percentage of Treg cells may serve as a clinical indicator to evaluate tumor load.

Objective To investigate the mechanism of extremely low frequency electromagnetic field (ELF-EMF) and X-ray irradiation on liver carcinoma cell lines BEL-7402. Methods Liver carcinoma cell lines BEL-7402 had been incubated with ELF-EMF (100 Hz, 0.7 mT, 30 min, 3 days) after X-ray irradiation at different doses (0, 2, 4, 6, 8,10 Gy). The cells were observed on morphologic changes with scanning electron microscope. Flow cytometry and gene microarray were used to investigate the mechanism of cell apeptosis. Results ELF-EMF plus X-ray induced apoptosis on BEL-7402 was observed under scanning electron microscope.When X-irradiation was 2, 4, 6, 8 and 10 Gy, the apoptosis ratios of combined group and only X-irradiation group were 10.0%, 14.5%, 4.3%, 5.1%, 7.1% and 0.1%, 8.1%, 0.1%, 0.4%, 2.2% (P < 0.05) on flow cytometry. The result of microarray indicated that 1465 genes were up-regulated and 1108 down*regulated in the ELF-EMF plus X-ray group in comparison with the control group. The change rates of 110 apoptosis related genes were above 2 times, which including 71 up-regulated and 39 down-regulated. Gene microarray showed that ELF-EMF and X-ray irradiation had a mainly effect on different gene of apoptosis paths (CDC25 and CHKI, ATM, p38, PTEN, p53, G1/S, Fas, G2/M, Cell Cycle, Apoptosis and Caspase). The same genes of ELF-EMF plus X-ray group were showed 13 in ELF-EMF group and 42 in X-ray group. Conclusions Apoptosis paths were significantly different between ELF-EMF and X-irradiation. ELF-EMF cooperates with X-irradiation on inducing BEL-7402 cell apoptosis.

Objective To determine the expression differences of Basigin(BSG)mRNA between early ischemic myocardium(EIM) and non-ischemic myocardium(NIM) in rats and then to evaluate the possibility of BSG examination in ischemic myocardium accidents occurred in forensic medicine. Methods Real-time polymerase chain reaction (RT-PCR) technique was applied for detecting the expression of BSG mRNA in EIM and NIM of rats at 15min, 30min, 1h and 2h post myocardial ischemia, and in sham operation(SO) group. Results Compared with NIM, SO and control groups, expression of BSG mRNA decreased after 15min when myocardium ischemia occurred; compared with SO, it was of 0.5 folds when 1h(P<0.5), and rebounded to SO level when 2h. Conclusion BSG could be involved in protection and myocardial remodeling in early ischemic myocardium, and may serves as a biomarker of early ischemic myocardium.

Objective To investigate the role of ceramide pathway in cell proliferation and early apoptosis induction in U251 glioma cell after cannabinoid receptora agent anandmide(AEA)treatment.Methods U251 gliom cells were treated with AEA(1-10 μmol/L),Ceramide(5-20 μmol/L) and fumonisin B1 (FB1) (10 μmol/L) pretreatment.The growth inhibition rate of U251 was investigated by MTT assay.The early events of the apoptosis were measured by flow cytometry using annexin-V/propium iodide(PI) double staining method.Results Different concentrations of AEA inhibited the proliferation of human glioma U251 cells,and had synergistic effect with CM by FB1(10 μmol/L)pretreatment for 24 h.After exposure to AEA(10 μmol/L)for 24 h,U251 gliomacells could undergo the early cell apoptosis which was affected by FB1(10 μmol/L).Conclusion AEA through the CM de novo synthesis pathway,and CM concentration was lazy in collaboration,thus inhibiting human glioma U251 cell proliferation and induce early apoptosis.

Objective To evaluate the efficacy between cylindrical abdominoperineal resection(CAPR)by laparoscopy and traditional abdominoperineal resection(APR). Methods A retrospectively analysis was done in the data of patients with low rectal cancer who underwent APR in our department from January 2010 to September 2015. The patients were divided into two groups,including cylindrical abdominoperineal resection by laparoscopy and traditional abdominoperineal resection. The operation time,intraoperative bleeding,the time of intestinal exhaust as well as the postoperative complications of the two groups were compared. Results There were no statistical differences in the intraoperative bleeding,operation time,the time of intestinal exhaust,postoperative intestinal obstruction and pulmonary infection between the two groups(P > 0.05). However,the differences in the rates of perineal incision infection and tumor intestinal perforation between the two groups were statistically significant (P < 0.05). Conclusion CAPR by laparoscopy is safer,more reliable than traditional APR,which can effectively reduce the rates of postoperative incision infection and tumor intestinal perforation of patients.
