OBJECTIVE: Study on the correlation between chronic sinusitis with nasal septum deviation. METHOD: Randomly selected 722 patients with coronal sinuses CT, statistics the number of cases of nasal septum deviation, cases of nasal septum deviation with chronic sinusitis, the wide and narrow side cases of nasal septum deviation complicated with sinusitis. The number of sinusitis without deviation, and paired test. RESULT: The incidence of sinusitis between deviation of nasal septum and non deviation were 54. 13% and 44. 66%, the difference between two groups was statistically significant (P<. 05), the incidence of sinusitis with nasal septum deviation of wide and narrow side were 31. 65% and 32. 12%, no significant difference between the two groups (P>0. 01). The incidence of sinusitis high deviation and non high deviation were 59. 54% and 46. 97%, the difference between the two groups was statistically significant (P<0. 05). The number of wide side of upper nasal septum deviation with sinusitis was 54, the narrow side was 66, there is no significant difference between the two groups (P>0. 05). CONCLUSION The deviation of nasal septum is associated with the formation of chronic sinusitis, the high deviation is more prone to sinusitis, The incidence of sinusitis and nasal septum deviation on both sides was no different.

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.

A high performance liquid chromatographic assay has been developed for the simultaneous determination of four water soluble vitamins,thia min, ribo-flavin, uiacin and pyridoxine, in cereal products and fresh vegetables. For hydrolyzing sample in 0.4 mol/L HCL, autoclaving at 120℃, 15 psi for 30 minutes, a ?Bondapak column (300mm ? 3.9mm, Waters Co), a mobile phase of methanol-water (30:70) (0.005 mol/L heptanesulfonic acid) and a flow rate of 1.0ml/min gave the most satisfactory separation of the four vitamins. A double channel detector was used: three vitamins (B1, B2 and B5) were detected by UV spectrophotometry (254 nm) first, pyridoxine (B6) was detected by fluorometry (EX 290 nm, EM 390 nm) afterwards. Detection limits were 2, 5, 5 and 2ng, linear ranges were 5-40 ng, 5-50 ng, 5-40 ng and 5-50 ng for B1, B2, B5 and Be, respectively. Recoveries were 91.3%-102% (B1), 103%-105% (B2), 92%-100% (B5) and 99%-100% (B6), comparing with reference method and checking with food composition tables, very satisfactory results were obtained by this method.

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.

A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.
