BACKGROUND: It has confirmed that angiotensin converting enzyme inhibitor benazepril can delay fibrosis of varied organs. However, whether benazepril has inhabited effect on peritoneal fibrosis in the process of peritoneal dialysis is poorly understood. OBJECTIVE: It is assumed that benazepril could inhabit peritoneal fibrosis of peritoneum with peritoneal dialysis, in addition, to compare the effect to other mehods. METHODS: All rats were randomly and evenly divided into 4 groups. There was no intervention in the control group; saline solution, and 20 mL 42.5 g/L Dianeal solution, was injected into rats in the saline solution and peritoneal dialysis groups; in the combination group, 20 mL 42.5 g/L Dianeal solution was injected combined with oral taken benazepril 20 mg/(kgd). The intraperitoneal injection performed once a day, for 4 successive weeks. The ultrafiltration function was performed 4 weeks later. Meantime, Paraffin sections were cut and stained by Van Gieson to measure peritoneal thickness. RESULTS AND CONCLUSION: Two rats in the peritoneal dialysis group and 1 rat in the combination group were dead. The remained 37 rats were included in the final analysis. Compared to the control and saline solution groups, the ultrafiltration volume of the peritoneal dialysis and combination groups were obviously decreased (P all < 0.05), especially notably decreased in the combination group (P < 0.05). Compared to the control group and saline solution groups, the peritoneal thickness was significantly elevated in the combination group, but not as much as in the peritoneal dialysis group (P < 0.05). In the long-term peritoneal dialysis rats, administration of benazepril can effectively protect the ultrofiltration function of peritoneum and delay the progression of peritoneal fibrosis.

Background. Herb-derived compound andrographolide sulfonate (called Xiyanping injection) recommended control measure for severe hand, foot, and mouth disease (HFMD) by the Ministry of Health (China) during the 2010 epidemic. However, there is a lack of good quality evidence directly comparing the efficacy of Andrographolide Sulfonate combination therapy with conventional therapy. Methods. 230 patients were randomly assigned to 7-10 days of Andrographolide Sulfonate 5-10 mg/Kg/day and conventional therapy, or conventional therapy alone. Results. The major complications occurred less often after Andrographolide Sulfonate (2.6% versus 12.1%; risk difference [RD], 0.94; 95% CI, 0.28-1.61; P = 0.006). Median fever clearance times were 96 hours (CI, 80 to 126) for conventional therapy recipients and 48 hours (CI, 36 to 54) for Andrographolide Sulfonate combination-treated patients (χ 2 = 16.57, P < 0.001). The two groups did not differ in terms of HFMD-cause mortality (P = 1.00) and duration of hospitalization (P = 0.70). There was one death in conventional therapy group. No important adverse event was found in Andrographolide Sulfonate combination therapy group. Conclusions. The addition of Andrographolide Sulfonate to conventional therapy reduced the occurrence of major complications, fever clearance time, and the healing time of typical skin or oral mucosa lesions in children with severe HFMD. © 2013 Xiuhui Li et al.

Background: Myocardial siderosis is the most common cause of death in patients with beta thalassemia major(TM). This study aimed at investigating the occurrence, prevalence and severity of cardiac iron overload in a young Chinese population with beta TM. Methods and Results: We analyzed T2*cardiac magnetic resonance (CMR), left ventricular ejection fraction (LVEF) and serum ferritin (SF) in 201 beta TM patients. The median age was 9 years old. Patients received an average of 13 units of blood per year. The median SF level was 4536 ng/ml and 165 patients (82.1%) had SF>2500 ng/ml. Myocardial iron overload was detected in 68 patients (33.8%) and severe myocardial iron overload was detected in 26 patients (12.6%). Twenty-two patients ≤10 years old had myocardial iron overload, three of whom were only 6 years old. No myocardial iron overload was detected under the age of 6 years. Median LVEF was 64% (measured by CMR in 175 patients). Five of 6 patients with a LVEF<56% and 8 of 10 patients with cardiac disease had myocardial iron overload. Conclusions: The TM patients under follow-up at this regional centre in China patients are younger than other reported cohorts, more poorly-chelated, and have a high burden of iron overload. Myocardial siderosis occurred in patients younger than previously reported, and was strongly associated with impaired LVEF and cardiac disease. For such poorly-chelated TM patients, our data shows that the first assessment of cardiac T2*should be performed as early as 6 years old. © 2014 Yang et al.

To identify new genetic risk factors for cervical cancer, we conducted a genome-wide association study in the Han Chinese population. The initial discovery set included 1,364 individuals with cervical cancer (cases) and 3,028 female controls, and we selected a 'stringently matched samples' subset (829 cases and 990 controls) from the discovery set on the basis of principal component analysis; the follow-up stages included two independent sample sets (1,824 cases and 3,808 controls for follow-up 1 and 2,343 cases and 3,388 controls for follow-up 2). We identified strong evidence of associations between cervical cancer and two new loci: 4q12 (rs13117307, Pcombined, stringently matched = 9.69 × 10-9, per-allele odds ratio (OR)stringently matched = 1.26) and 17q12 (rs8067378, Pcombined, stringently matched = 2.00 × 10-8, per-allele ORstringently matched = 1.18). We additionally replicated an association between HLA-DPB1 and HLA-DPB2 (HLA-DPB1/2) at 6p21.32 and cervical cancer (rs4282438, Pcombined, stringently matched = 4.52 × 10-27, per-allele ORstringently matched = 0.75). Our findings provide new insights into the genetic etiology of cervical cancer. © 2013 Nature America, Inc. All rights reserved.

As a pro-inflammatory cytokine, interleukin-32 (IL-32) is reported to play an important role in tumor development and progression. However, its effects on the invasion and motility of osteosarcoma cells remain elusive. The aim of the present study was to determine the molecular mechanisms of IL-32 in osteosarcoma cells using RT-PCR and western blot analysis. The results showed that IL-32 stimulation dose-dependently promoted the invasion and motility of osteosarcoma cells. Knockdown of endogenous IL-32 by siRNA inhibited osteosarcoma cell invasion and motility. Moreover, IL-32 induced the activation of AKT in a time-dependent manner. IL-32 stimulationwas also capable of increasing the expression and secretion of matrix metalloproteinase (MMP)-13, which is involved in tumor invasion and metastasis. In addition, blockade of AKT activation suppressed IL-32-mediated invasion, motility and MMP-13 upregulation in osteosarcoma cells. Taken together, our results suggest that IL-32 stimulation promotes the invasion and motility of osteosarcoma cells, possibly via the activation of AKT and the upregulation of MMP-13 expression. Thus, IL-32 may serve as a marker for diagnosis, as well as for the treatment of osteosarcoma.
