Technique and clinical outcome of catheter ablation guided by remote magnetic navigation for ventricular arrhythmias originating from outflow tract / 上海交通大学学报（医学版）

Objective· To assess the clinical outcome of catheter ablation guided by remote magnetic navigation(RMN) for ventricular arrhythmias (Vas) including ventricular tachycardia (VT) and ventricular premature complex (PVC) originating from ouflow tract (OT). Methods · A total of 42 patients with idiopathic VT/PVC originated from outflow tract were enrolled. All the patients underwent catheter ablation guided by RMN and 3D Carto mapping system. OT-Vas were divided into two groups:right ventricular outflow tract(RVOT) group and left ventricular outflow tract(LVOT) group. Vas arising from LVOT were mapped and ablated by transaortic retrograde and/or transseptal puncture approaches. The primary study endpoint was acute success rate. The secondary study endpoints were procedure-related parameters, including operator X ray time, ablation time, procedure time and complications. Vas recurrence was detected by Holter electrocardiograph (ECG) which was followed-up at 3 months, 6 months and 1 year after ablation. Results · 74% (31/42) Vas arised from RVOT. 93% (39/42) OT-Vas were achieved acute success. The acute success rate was not different between Vas from RVOT and LVOT (30/31 vs 9/11,P=0.160).Compared to LVOT group,the ablation time and fluoroscopic time of RVOT group were significantly reduced s by 31%(P=0.020) and by 33% (P=0.004). There was no major complication in two groups. Within the 11 cases of LVOT-Vas, 4 LVOT-Vas cases which were ablated by tansaortic retrograde with failure were transferred to transseptal approach and ablated successfully. At one-year follow-up, frequent PVCs recurred in 2 out of 39 patients with acute success. Conclusion · Catheter ablation using RMN for OT-Vas is safe and effective with relatively short operator's X-ray time. For LVOT-Vas, mapping and ablation guided by RMN through transseptal approach can improve the acute success rate.

Distribution of Vibrio alginolyticus-like species in Shenzhen coastal waters, China

We investigated the distribution of vibrios in Shenzhen coastal waters in order to obtain valuable information for the aquaculture industry and a health warning system. Quantities of vibrios from surface waters ranged from 0 to 4.40×10(4) CFUs mL-1 in April (spring), while from 0 to 2.57×10³ CFUs mL-1 in September (autumn); the abundance of V. alginolyticus-like species from surface water ranged from 0 to 6.72×10³ CFUs mL-1 in April (spring) and from 0 to 1.28×10³ CFUs mL-1 in September (autumn); higher counts were observed in spring. The V. alginolyticus-like species was dominant in Shenzhen coastal waters, with the highest abundance in the clean region (stations YMK001 and GDN064) in April, suggesting that Vibrio spp. were naturally occurring bacteria in marine environments. The correlation between the abundance of vibrios (including V. alginolyticus-like species) and environmental factors varied in different regions and different seasons. There were no vibrios detected when the salinity was less than 11.15ë in the Zhujiang River estuary, which indicated that salinity played a key role in the distribution of vibrios and V. alginolyticus-like species.

Effects of L-lysine monohydrochloride on insulin and blood glucose levels in spinal cord injured rats / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Hyperglycemia in brain and spinal cord could aggravate neurologic impairment. Recent studies showed that L-lysine monohydrochloride (LMH) could increase the insulin secretion and regulate the blood glucose level. The aim of the present study was to investigate the effects of LMH on pancreatic islet B cells, the levels of endogenous insulin and blood glucose in spinal cord injured rats.</p><p><b>METHODS</b>Forty male Wistar rats were divided into four groups, namely, normal control group, model group, high-dose LMH group (621.5 mg/kg equal to LMH 1/8 LD50), and low-dose LMH group (310.8 mg/kg equal to LMH 1/16 LD50). The model of spinal cord injured rat was established by hemi-transection at the lower right thoracic spinal cord. LMH was administered via intraperitoneal injection once spinal cord injury was produced in rats. All rats were sacrificed 48 hours after spinal cord injured. The effects of LMH on pancreatic islet B cells, the content of endogenous insulin, and the level of blood glucose were observed with immunohistochemical method, radioimmunoassay method, and biochemical analyzer, respectively.</p><p><b>RESULTS</b>The insulin immunohistochemical intensities of islet B cells were significantly weaker in model group than those in normal control group (P < 0.01). The levels of endogenous insulin were significantly lower and the blood glucose levels were significantly higher in model group than those in normal control group (P < 0.01). The insulin immunohistochemical intensities of islet B cells were significantly stronger in high-dose LMH group than those in model group (P < 0.05). In addition, we found that the levels of endogenous insulin were significantly higher and the blood glucose levels were significantly lower in high-dose LMH group than those in model group (P < 0.05). There were no significant differences in the insulin immunohistochemical intensities of islet B cells, the levels of endogenous insulin and the blood glucose between low-dose LMH group and model group (P > 0.05).</p><p><b>CONCLUSION</b>LMH, but dose-dependent, might participate in the regulation of pancreatic islet B cells, and then reduce the blood glucose levels in the spinal cord injured rats.</p>

Efficacy of diacetyl hexamethylene diamine in treatment of patients with high risk myelodysplastic syndrome / 中国实验血液学杂志

The aim of this study was to investigate the efficacy of diacetyl hexamethylene diamine (CAHB) for patients with high risk myelodysplastic syndrome (MDS), and to explore the effect of CAHB on HL-60 cells in vitro and its possible mechanism. 8 patients with high risk MDS were treated with CAHB by continuous intravenous infusion for 10 days, and repeated once after an interval of 28 days. The count of the granulo- and mono-blasts in bone marrow (BM) aspirate was measured before and after treatment. HL-60 cells were treated with different concentrations of CAHB for 72 hours in vitro. The inhibitory effect of CAHB on proliferation of HL-60 cells in vitro was measured by MTT assay. Differentiation of HL-60 cells was detected by the changes of CD11b and CD14 expression on cell surface. Apoptosis of HL-60 cells was detected by double staining of Annexin V and PI. The cell cycle distribution change of HL-60 cells was analyzed by flow-cytometry. The results indicated that the granulo- and mono-blasts in BM decreased in all the 8 patients after CAHB treatment. The main side effect of CAHB on hematological system was thrombocytopenia. After being treated with 1, 2, 3, 4 mmol/L CAHB for 72 hours in vitro, the result of MTT assay showed the inhibitory effect of CAHB on the proliferation of HL-60 cells in dose-dependent manner. After being treated manner 1, 2, 3, 4 mmol/L CAHB for 72 hours, the CD11b positive HL-60 cells were 22.39+/-3.97%, 33.12+/-4.46%, 49.25+/-5.27%, 78.05+/-5.66%, respectively, which were significantly different from the control group (CD11b positive HL-60 cells was 5.89+/-2.94%) (p<0.01). The CD14 expression was negative in all the 5 groups. These results suggested that CAHB could induce HL-60 cells to differentiate into mature granulocytes, and the effect of CAHB appeared in dose-dependent manner. After being treated for 72 hours by 1, 2, 3, 4 mmol/L CAHB, the apoptotic cells (Annexin V(+)/PI(-) cells) increased mildly, which suggested that CAHB only weakly induces HL-60 cells to apoptosis at the concentration of 1 to 4 mmol/L. Along with the concentration increase of CAHB, the ratio of cells in G(0)/G(1) phase increased, and ratio of cells in S phase and G(2)/M phase decreased correspondingly, it indicated that CAHB could arrest HL-60 cells in G(0)/G(1) phase in a dose-dependent manner. It is concluded that induction of cell differentiation may be the primary effect of CAHB on MDS. Cell cycle arrest may be essential to the effect of CAHB as well. Side effect of CAHB on platelet count may correlated with its inhibitory effect on hematopoiesis.

Study of embryonic stem cells induced to express hepatic cell functions in vitro in a pathologic niche containing cholestatic serum / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the role of a pathologic niche inducing mouse embryonic stem cells (ESC) to express hepatic cell functions in vitro.</p><p><b>METHODS</b>Embryoid bodies were developed from 5 to 7 day hanging-drop culture of mouse ESC, and their dissociated cells were planted in three differential systems: nothing added; with 20 ng/ml hepatocyte growth factor (HGF); and 5% rat cholestatic serum plus 20 ng/ml HGF added. Their differentiation was observed with inverted microscopes daily, and their hepatic functions were analyzed against their synthesis of glycogen, triglycerides, albumin, and urea nitrogen, and by their staining of indocyanine green (ICG) and fluorescein diacetate (FDA).</p><p><b>RESULTS</b>ESC spontaneous differentiation was hardly being controlled to form three germ layers. HGF prompted the ESC to develop further into visceral endoderm and mesoderm (myocardium), but both of them only expressed a low level of hepatocyte-specific metabolic functions. With cholestatic serum added into the HGF-induced system, differentiated cells grew into similar angular cells, and had a higher level synthesis of glycogen, triglycerides, albumin and urea nitrogen with positive ICG and FDA staining.</p><p><b>CONCLUSIONS</b>Spontaneous or HGF-induced ESC differentiation has only limited hepatic functions expressed. A pathologic niche in vitro induces ESC to develop into hepatic lineages, with a higher level of hepatic metabolic functions.</p>
