Analysis of the correlation between blood pressure fluctuation and hemodialysis-related complications in patients with maintenance hemodialysis / 上海交通大学学报（医学版）

Objective : To explore the correlation between blood pressure fluctuation and chronic kidney disease-mineral and bone disorder (CKD-MBD) in patients with maintenance hemodialysis (MHD). Methods ¡¤ From Jan. 2009 to Apr. 2015, 433 MHD patients in Hemodialysis Center of Renji Hospital, Shanghai Jiao Tong University School of Medicine were included, and their clinical data, treatment parameters during dialysis, lab examination indexes and drug applications were collected. According to the difference value of systolic blood pressure (SBP) during dialysis period, all the patients were divided into high fluctuation group of blood pressure (|△ SBP| ≥ 10 mmHg, n=234) and low fluctua-tion group of blood pressure (|△ SBP|<10 mmHg, n=199). The blood pressure fluctuation and its relationship with dialysis adequacy, bone metabolism indicator and nutrition indicator were analyzed between the two groups. Results ¡¤ Compared with the low fluctuation group of blood pressure, the patients in the high fluctuation group of blood pressure took higher proportion of β receptor blockers and Vit D, higher level of serum P and intact parathyroid hormone (iPTH), higher dialysis age, and lower Kt/V, ultrafiltration volume, body mass index (BMI) and serum albumin (ALB) level (all P<0.05). The blood pressure fluctuation between the patients with different serum P and iPTH levels was statistically significant (all P<0.05). There was no statistically significant difference in blood pressure fluctuation between the patients with different serum Ca levels. Multivariate Logistic regression analysis showed that dialysis age, serum P and iPTH levels were independent risk factors for blood pressure fluctuation of MHD patients, while Kt/V and ALB were protective factors. Con-clusion ¡¤ Blood pressure fluctuation in MHD patients during dialysis period is significantly correlated with CKD-MBD, nutritional status, dialy-sis age and dialysis adequacy.

Effects of Rb1 and Rg1 on the expression of Bcl-2, Bax in apoptosis of HK-2 cells induced by the serum of kidney ischemia/reperfusion / 中国应用生理学杂志

<p><b>AIM</b>To explore effects of Ginsenosides (Rb1, Rg1) on the expression of Bcl-2, Bax in the serum of kidney ischemia/reperfusion inducing apoptosis of HK-2 cells.</p><p><b>METHODS</b>The serum of rabbits with renal ischemia/reperfusion (SIR) and the control serum of rabbits (SC) were acquired and cultured with HK-2 cells. Detected apoptosis with TUNEL assay. The experiment was designed as: control group,ischemia/ reperfusion group, Rb1 blocking group and Rg1 blocking group. To detect the expression of Bcl-2, Bax with immunocytochemistry after 24 hours' cultured.</p><p><b>RESULTS</b>The expression of Bax in Rb1 blocking group and Rg1 blocking group were significantly decreased (P < 0.01), the ratios of Bcl-2/Bax were increased as compared with ischemia/reperfusion group.</p><p><b>CONCLUSION</b>Rb1 and Rg1 have protective effects on apoptosis of HK-2 cells induced by serum of kidney ischemia/reperfusion.</p>

The investigation of HEV epidemiology, inferior clinical infection and viral-toxemia in blood donors in Quzhou area / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the infection of HEV in Quzhou area of Zhejiang Province.</p><p><b>METHODS</b>All sera from blood donors in the central blood bank of Quzhou from April 2006 to April 2007 were used. Anti-HEV IgG and anti-HEV IgM were measured by EIA. RT-PCR was also performed to the samples with positive anti-HEV IgM. Genotype and sequence homology were analyzed after sequencing.</p><p><b>RESULTS</b>The positive ratio of anti-HEV IgG was 40.60%, in which the male infection ratio was higher than the female significantly (43.09% VS 36.09%; chi2=22.6; P < 0.01). The infection ratio was increased with age. The positive ratio of anti-HEV IgM was 0.43%. The positive ratio of anti-HEV IgG and the titers of antibody were higher in the inferior clinical infectors with positive anti-HEV IgM than the negative ones (P < 0.05). Two samples were positive in HEV PCR among 21 samples with positive anti-HEV IgM. The toxemia ratio was 0.4% of all the donors. And the genotype of the two samples with toxemia were both HEV-IV.</p><p><b>CONCLUSION</b>The HEV infection was correlation with age and sex significantly and the infection occurred in the adults mainly in Quzhou area. HEV toxemia was not infrequency in the blood donors.</p>
