Forty cases of nonbacterial prostatitis were treated by pricking therapy, and another 40 cases were treated by norfloxacin capsul and flavoxate hydrochloride tablets as the control. The result showed the effective rate was 100% in the former and 95% in the latter,and there was a statistical difference in therapeutic effect between two groups(P ＜ 0.05).Pricking therapy had a good effect on the nonbacterial prostatitis.

Objective To investigate the effect and mechanism of p38 MAPK inhibition in reducing the damage to rat's hippocampal neurons caused by kainic acid (KA) and observe the three-dimensional morphological changes on the cell surface. Methods The rat's hippocampal neurons cultured primarily for 10 days were pretreated with SB203580 (0.2 ?mol/L, a p38 MAPK inhibitor). Thirty minutes later, the hippocampal neurons were administered with KA at concentrations of 0, 25 and 250 ?mol/L for action for 10 and 100 minutes respectively. The cellular membrane structure was scanned and examined at nano-level by using atomic force microscope. Results Normal neurons displayed smooth membrane surface with homogeneous and regular undulation. In contrast, the neurons treated with KA showed coarse membrane surface with holes. Furthermore, the degree changes increased with the action time and the KA concentrations in a dose-effect dependent fashion. The above-mentioned changes were obviously mitigated by means of pretreatment with SB203580 (200 nmol/L). Conclusions Inhibition of p38 MAPK may, in certain degrees, protect the neurons against the impairments on cytomembrane resulted from the toxic effect of KA.

Aplastic anemia (AA) refers to a life-threatening bone marrow failure disorder.With respect to the precise pathophysiology of AA at present, it is still unclear.MicroRNA (miRNA), about 22 nucleotides in length, is a kind of small RNAs and it can regulate gene expression post-transcriptionally.According to domestic and foreign reports recently, there are abnormal expressions of several miRNAs in AA patients, suggesting that miRNAs may be involved in the development and progression of AA.This article reviews the study progress of miRNAs in AA.

Objective To explore the new method to prevent graft versus host disease (GVHD) by clearing T lymphocytes of bone marrow graft through Fas-FasL way. Methods FasL-cDNA was transfected into BALB/C mouse hematopoietic cells by liposomes. The transfected cells were cultured together with BAC mice bone marrow graft. The mixed bone marrow graft was injected into BALB/C mouse recipients after 60 Co-? ray irradiating. Then the mortality, manifestation and pathologic change of GVHD of recipient mice were observed. Results Compared with control group, the mortality of the recipients in the experimental group was markedly decreased in 60 days (20% vs 70%, P

0.05).Conclusions The expression of galetin-3 was obviously increased in liver metastasis from colon cancer,and MCP can effectively inhibit the development of liver metastasis of colon cancer.

Objective To investigate the effects of co-exposure to LPS and heat on plasma tumor necrosis factor-? (TNF-?), interleukin-6 (IL-6), malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in rats. Methods Male pathogen-free Wistar rats were randomly assigned to the following groups: saline-injected normothermic control (Group C), saline-injected heat exposure (Group H), LPS-injected normothermic control (Group L), LPS-injected heat exposure (Group HL). Mean arterial pressure (MAP) was continually monitored. Plasma levels of TNF-?, IL-6, MDA and SOD were determined at 0, 40, 80, 120 min. Results The rats in Group HL displayed much lower MAP, higher MDA and lower SOD than the other 3 groups. The rats in Group HL displayed an early rise in plasma TNF-?, IL-6 at 40 min, the peak values of both at 80 min significantly higher than the other three groups at the same time piont. Conclusion Co-exposure to LPS and heat primes the rats to advance and augment systemic inflammatory response syndrome.

Folic acid-O-carboxymethyl chitosan ultrasmall superparamagnetic iron oxide nanoparticles (FA-OCMCS-USPIO-NPs) are a novel molecular targeting MR contrast agent. This paper reperts the pharmacokinetics and magnetic resonance response characteristics of FA-OCMCS-USPIO-NPs in normal rats and mice, and discussed its distributing regularity in animals, providing basis for tumor targeting imaging. O-phenanthroline method was used to determine iron content in rats' plasma and mice's organs following high and low doses of nanoparticles injected through tail vein, and the blood concentration-time curve was drawn, the calculated t1/2 of two groups were greater than 7 h. The results of tissue distribution showed that only a small part of nanoparticles were swallowed by the liver and spleen, while none in the heart, lung and kidney. At the same times, the phagocytosis of nanoparticles did not change with the dose. The results of MRI showed that renal excretion occurred 4 hours after injection, and signal to noise ratio (SNR) of liver and kidney returned to normal levels 24 hours after injection. There were no nanoparticles in the lungs. So a part of nanoparticles escaped from phagocytosis of liver and spleen, and it owned lower toxicity and longer half-life. indicated its use for tumor-targeting imaging. All of these indicated its use for tumor-targeting imaging.

Objective To investigate the correlation between the frequency of myeloid-derived suppressor cells (MDSC) and the frequency of regulatory T cells (Treg) in the peripheral blood in patients with chronic hepatitis B (CHB) and its clinical significance.Methods A total of 45 CHB patients including 23 mild-to-moderate CHB patients,22 severe CHB patients,and 15 healthy controls were enrolled.The frequencies of MDSC and Treg in the peripheral blood were studied using flow cytometry and its correlation with clinical data was analyzed by Sepearman correlation analysis.Results The median frequency of MDSC in CHB patients was 0.414％,which was significantly higher than that in healthy controls 0.226％ (Z=-2.356,P=0.018 9).The frequency of MDSC in CHB patients was negatively correlated with the level of alanine transaminase (ALT) and aspartate transaminase (AST) (r=-0.480,-0.478; both P＜0.01),but had no relations with hepatitis B virus (HBV) viral load (r=-0.049,P=0.75).An increase frequency of MDSC was observed in CHB patients with an ALT of 5 × upper limits of normal (ULN) or less or AST of 3 × ULN or less.The frequency of MDSC in CHB patients was positively correlated with that of Treg (r =0.345,P =0.02).Conclusions The activation and proliferation of MDSC may facilitate and maintain HBV persistent infection.The change of the frequency of MDSC is in line with that of Treg,indicating that immunosuppressive functions of MDSC may be related with the development of Treg in CHB.
