Objective:To investigate the protective effects of neferine on lipopolysaccharide ( LPS)-induced human umbilical vein endothelial cells ( HUVECs) injury. Methods:The optimum inducing concentration of LPS was screened out through pretests and used for the model establishment of HUVECs damage. CCK8 was used to detect the influence of neferine at different concentrations on LPS-induced human umbilical vein endothelial cells ( HUVECs) injury. Nitric oxide ( NO) content was measured by the Griess Reagent method. The nitric-oxide synthase (NOS) activity was assessed by the commercially available kits. Results:The inhibitory rate of HU-VECs was 54. 50% detected by CCK8, which induced by LPS at the concentration of 100 μg·ml-1(P<0. 01). Neferine at the con-centrations of 0. 3-5. 0μmol·L-1 could increase the cell viability in a concentration-dependent manner, while it inhibited the cell pro-liferation at the concentration of 10 μmol·L-1(P<0.05). Neferine could reverse the situation, and the NO release was increased and the tNOS/iNOS activity was increased induced by LPS (P<0. 05). The results shown by the inverted microscope suggested that the floating dead cells were decreased, the cell shape was basically sound and tightly packed with the concentration increase of neferine (0. 3-5. 0μmol·L-1) in a concentration-dependent manner. Conclusion:The results show that neferine has protective effects on HU-VECs injury induced by LPS, and the mechanism may be related with the decrease of intracellular levels of NO and NOS activity.

Objective:To compare the inhibitory effect of neferine and isoliensinine on 5α-reductase to provide reference for the development of 5α-reductase inhibitors. Methods: Different reaction tubes and control tubes were prepared, liver was homogenated, and reducing coenzyme II ( NADPH) , testosterone, pending test sample, the positive drug and buffer was respectively added into 96-well plates. The change in the absorbance of NADPH at 340nm in 1h was determined by a microplate reader. Compared the experimen-tal group with the blank control group, the inhibition rate ( I%) of the test drugs against 5α-reductase was calculated. Results:As for the six concentration gradients (2-40 mg·ml-1 ) in the experiments, the best inhibitory concentration of neferine and isoliensinine was 10 mg·ml-1(I% =25.00 ±1.030% and 29.90 ±2.410%, respectively). Compared with the control group, neferine and isoliensi-nine showed significant inhibition against 5α-reductase (P<0. 05). Compared with the positive group at the same concentration (10 mg ·ml-1), the inhibition of neferine and isoliensinine was significantly lower (P<0. 05). The inhibition effect of isoliensinine was rel-atively better than that of neferine (P<0. 05). Conclusion:Neferine and isoliensininein have notable inhibitory effect on 5α-reduc-tase, which show certain application prospect in the treatment of prostatic hyperplasia in clinics.

OBJECTIVE: To evaluate the protective effects of oral administration of D-methionine tablets on noise-induced hearing impairment. METHOD: Two hundred and three volunteers were recruited and randomly divided into two groups: experimental group (n= 113) and control group (n=90). The subjects received oral administration of D-methionine tablets in the experimental group and placebo in the control group before noise exposure. Routine audiometric evaluation and ABR testing were performed and recorded before and after noise exposure. The statistical analysis was carried out with SPSS 11.0. RESULT: There were no differences in auditory threshold and I-V interpeak latency pre-noise exposure (P>0.05), however, there were statistically significant differences between two groups 1 d, 7 d after noise exposure (P<0.01 and P<0.05). In-respective-group, there were statistically significant differences between before and 1 d after noise exposure (P<0.05 and P<0.01), however, no difference was noted between before and 7 d after noise exposure in the experimental group (P>0.05). CONCLUSION The protective effects of D-methionine tablets were prominent on the noise-induced hearing impairment. Further studies regarding the optimal time of D-methionine administration will be recommended in the future.

Ahigh-resolutionmethodforhumanleukocyteantigen-B(HLA-B)genotypingwasestablished based on the optimized polymerase chain reaction, cloning and sequencing technology. The exon2 and exon3 of HLA-B gene were amplified with primers based on the HLA-B gene sequence. These produced heterozygous alleles were effectively cloned into plasmid DNA based on the principle of plasmid incompatibility, and were followed by bacterial culture. Then Sanger sequencing was carried out and after analyzing the result by software ClustalX2 and IMTG/HLA database comparison, the HLA-B genotype of the samples was achieved. Seven clinical samples were detected, and the results were consistent with those of PCR-SBT genotyping method. The method was cost-effective, high-resolution and it did not require technical software. The use of universal primers simplified the cumbersome design and optimization process of specific primers.

To investigate the effects of anti-sense peptide nucleic acids (PNAs) targeting Ki-67 gene on modulation of the proliferation and apoptosis of human renal carcinoma cell lines, human renal carcinoma cell line 786-0 cells were treated with anti-sense PNAs at different concentrations (1.0 micromol/L, 2.0 micromol/L, 10.0 micromol/L). The Ki-67 expression of 786-0 cells was detected by immunohistochemical technique and Western blot method respectively. The proliferation of 786-0 cells was studied by cell growth curves and 3H-thymidine incorporation. The apoptosis of 786-0 cells was detected by TUNEL assay. The control groups were treated with anti-sense oligonucleotide (ASODNs) targeting Ki-67 gene. Our results showed that the Ki-67 expression of 786-0 cells treated with anti-sense PNAs (16.9+/-0.7) was significantly inhibited as compared with that of the control groups (28.6+/-0.4) (P<0.01). The Ki-67 protein rate of 786-0 cells treated with anti-sense PNAs (42.1 +/-2.2) was significantly reduced when compared with that of the control groups (83.6+/- 1.4) (P<0.01). Proliferation of 786-0 cells treated with anti-sense PNAs (20.7+/- 1.5) was significantly inhibited as compared with that of the control groups (58.6+/- 1.4) (P<0.01). The apoptosis rate of 786-0 cells treated with anti-sense PNAs (28.7+/- 2.3) was significantly increased higher compared with that of the control groups (13.8 +/- 1.0) (P<0.01). From these finds we are led to conclude that anti-sense PNAs targeting Ki-67 gene have stronger effects on the inhibition of the proliferation and induction of apoptosis of human renal carcinoma cells than ASODNs targeting Ki-67 gene. The strategies using anti-sense PNAs targeting Ki-67 gene may be a promising approach for the treatment of renal cell carcinoma.
