Tinnitus is a common clinical disorder, which may generate trom a lot of causes, including otological disease and other systemic diseases associated with tinnitus or some factors such as insomnia and emotional cognition. Some studies have found that mood is associated with the occurrence and development of tinnitus and that psychological factors play a role in the occurrence and development of tinnitus in the tinnitus patients with mood disorders. At the same time, the psychological distress and emotional problems caused by tinnitus have drawn more and more attention of clinicians. Based on this, the cognitive theory of emotion can be helpful for evaluating tinnitus, and patients with severe tinnitus can be relieved by biofeedback information in tinnitus management. This article will analyze literature in these disciplines.

Objective To observe the effect of capsaicin on lipid deposition in liver cells and the expression of autophagy,to provide new ideas and targets for the study of fatty liver disease.Methods The model of nonalcoholic fatty liver disease (NAFLD) was established by inducing LGF cell line of liver primary cells with oleic acid (40 μg/mL).The experiment was divided into blank control group,oleic acid group,capsaicin group[oleic acid--capsaicin(100 μmol/L)].The level of intracellular lipid was detected by oil red O staining and triglyceride (TG) kit.Western bolt was used to detect the expression level of autophagy marker molecule p62 and LC3,and to calculate the ratio of LC3 Ⅱ/LC3-Ⅰ.Results After treated with 40 μg/mL oleic acid for 24 h,the oil red O staining showed that orange-red lipid droplets were found in the oleic acid group,but there was no obvious orange-red lipid droplet formation in the blank group,which suggesting that the NAFLD cell model was established successfully by using 40 μg/mL oleic acid in vitro.Oil red O staining was observed,the cells in the capsaicin group were significantly less than the oleic acid group,and the content of triglyceride in the liver cells was significantly lower than that in the oleic acid group(P＜0.05).Western bolt test results showed that capsaicin group p62 protein levels were significantly lower compared with the oleic acid group(P＜0.05),while the LC3-Ⅱ/LC3-Ⅰ ratio was higher than that of oleic acid group(P＜0.05).Conclusion NAFLD model was established by inactivating LO2 cell line with oleic acid in vitro.Capsaicin stimulated NAFLD cells,upregulated the autophagy level of NAFLD cells and reduced intracellular lipid deposition,but the specific mechanism need further study.

Objective:To compare the contents of polysaccharide and protein in male and female Trichosanthis Radix to provide reasonable explanation for that male plant was better. Methods:Polysaccharides in Trichosanthis Radix were obtained by water-extrac-tion and ethanol-precipitation method, and the content was determined by anthrone-sulfuric acid method. Tichosanthin ( TCS) was ob-tained by hydrochloric acid extraction and acetone precipitation. Based on the light absorption of Coomassie brilliant blue G-250 com-bined with proteins, the content of TCS was detected. Results: The polysaccharides content in male and female Trichosanthis Radix was 2. 628% and 3. 237%, TCS content was 0. 193% and 0. 280%, respectively. Conclusion: The contents of polysaccharides and TCS in male plant are higher than those in female plant. The male plant is a better source for Trichosanthis Radix.

Objective:To compare the content of amino acid in female and male plants of Trichosanthes kirilowii. Methods:Total protein was hydrolyzed by hydrochloric acid, and then determined by HPLC. Results:The percentage of amino acid in female and male plants of Trichosanthes kirilowii was 7. 35% and 7. 04%, respectively. Conclusion:The method provides a new idea for the determi-nation of amino acid in the root of Trichosanthes kirilowii. The total amino acid content in the root of male plants is lower than that of fe-male plants, while the content of alkaline amino acid is opposite. The content of histidine in male plants is about twice as much as that in female plants. The essential amino acid content has no significant difference.

Objective To explore the inhibiting effects of arsenic trioxide and cisplatin on MG-63 cells. Methods Using MTT assay,flowcytometry,phase contrast microscopy and electron microscopy methods,the therapeutic effect of arsenic trioxide was studied for the osteosarcoma in the cultured MG-63 cells in vitro,and compared these effects with cisplatin. The inhibitory rotes of cell growth and the effect of apoptosis and cell cycle were compared between arsenic trioxide and cisplatin on MG-63 cells. Results The contrast phase microscope revealed the adhesion ability of normal groups was good and cellular morphology showed epithelium cells. But the celhdar morphology showed irregular arrangement in arsenic trioxide groups and cytoplasmic vacuoles in cisplatin group. Electron microscope revealed the globular plasmalemma ecphymas in cell surface of control groups,the enlarged crista mitochondriales and the double-deck membrane structure appeared clearly. But electron microscope revealed globular plasmalemma processes in cell surface of arsenic trioxide groups,thinned crista mitochondriales and clearly seen karyopycnosis and nuclear membrane of apoptotic cells. The globular plasmalemma processes in cell surface of cisplatin groups were separated,nuclear membrane thickened and chromatin were in sandy shape. Both arsenic trioxide and cisplatin inhibited effectively MG-63 cells growth. There was a significant difference in different groups of inhibition ratios to the growth of cells(all P < 0.05). In 2,4,8,16,32,64,128 hours,the inhibition ratios(%) of arsenic trioxide(56.31±0.03,70.00±0.06,79.84±0.03,87.31±0.13,84.70±0.09,90.68±0.06,91.18±0.05) and cisplatin groups(7.55±0.15,15.70±0.17,30.72±0.07,49.80±0.05,45.11± 0.13,61.62±0.08,93.80±0.12) were obviously increased as compared with those in the control group(2.03± 0.07,2.78±0.08,3.11±0.01,5.67±0.04,12.23±0.04,18.65±0.04,24.45±0.04,all P < 0.05). Moreover the inhibition ratio of arsenic trioxide group in 2 to 32 hour was significantly higher than that of cisplatin group and the effect was more faster(all P < 0.05). Both arsenic trioxide and cisplatin could induce apoptosis MG-63 cells. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 13.317,P < 0.05). The inhibition ratios(%) of arsenic trioxide on 24,36,48 hour(20.50±3.78,45.76±9.90,25.16±15.41),and cisplatin groups on 24,36,48 hour(12.55±1.51,18.85±3.40,12.37±5.43),were obviously increased as compared with those in the control group at the same time(6.57±1.48,8.03±2.08,6.54±1.30,P< 0.05 or<0.01). Both arsenic trioxide and cisplatin inhibited MG-63 cells cycle. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 54.579,43.429,21.795,P < 0.05 or < 0.01). And the total inhibition ratios(%) in G1 cycle of arsenic trioxide(78.26±5.24) and cisplatin groups(80.48±2.81) were obviously increased as compared with those in the control group(57.49±6.65,all P < 0.05 or < 0.01). Conclusions Arsenic trioxide and cisplatin can effectively inhibit the proliferation of MG-63 cell line and induce the apoptosis of MG-63 cell line. And the effects induced by arsenic trioxide group were faster than that of cisplatin groups. Moreover arsenic trioxide can arrest the cell cycle of MG-63 cell line at G1 phase.
