Tinnitus is a subjective sensation of sound without external stimulation. It has become ubiquitous and has therefore aroused much attention in recent years. According to the survey, ameliorating tinnitus based on special music and reducing pressure have good effects on the treatment of it. Meantime, vicious cycle chains between tinnitus and bad feelings have been broken. However, tinnitus therapy has been restricted by using looping music. Therefore, a method of generating fractal tones based on musical instrument digital interface (MIDI) technology and pink noise has been proposed in this paper. The experimental results showed that the fractal fragments were self-similar, incompletely reduplicate, and no sudden changes in pitches and would have a referential significance for tinnitus therapy.

Objective To explore the anomalous effects of India buead and coix seed powder on phlegm-dampness constitution dyslipidemia through population-based intervention studies. Methods According to the experimental results of the model group with dyslipidemia, the phlegm-dampness population meeting the inclusion criteria were chosen as the samples for the randomized controlled trial, who were divided into test meal (21 males and 39 females) and blank control (23 males and 37 females) groups with 60 cases in each, aged 18 to 65 y and the total of 120 cases completed the study. Statistical analyses were performed with SPSS 18.0 statistical software. The self comparison wass conducted by the method of paired-sample t test and the comparison between groups was conducted by using independent sample t test. The categorical statistics were described as frequency and compared throughc2 test, P<0.05 was considered as statistically significant. Without changing the original way of life, the meal group having taken the India buead and coix seed powder was compared independently and with the control group for TC, TG, HDL-C and LDL-C to detect the trends and degrees of the level changes. Meanwhile, according to efficacy tests and standards, the changes in the level of TC, TG and HDL-C have been evaluated and the efficiency and total effective rates of all the variables have been calculated. Results After the intervention, there was a declining tendency in each variable, 8.9%in TC, 21.4%in TG, and 27.2%in LDL-C, except for an increase of 0.13 mmol/L in HDL. There were significant differences in the variables before and after the intervention (P<0.05 in each). As for the test meal group after the intervention, the effectiveness of TC has been obtained in 25 cases and inefficacy in 35 cases, with efficiency of 41.7%;the effectiveness of TG has been shown in 53 cases and inefficacy in 7 cases, with efficiency of 88.3%;the effectiveness of HDL-C has been gained in26 cases and inefficacy in 34 cases, with efficiency of 43.3%; and the total effective rate was 57.8%. Conclusions There are significant changes and improvements in TC, TG, HDL-C and LDL-C in the test meal group after the intervention with the powder, which demonstrate that the powder is effective in the reduction of TG for animals with dyslipidemia and populations with phlegm-dampness constitution.

OBJECTIVE: To investigate the protective effects of the ethanol extract of Radix et Rhizoma Gentianae on acute lung injury (ALI). METHODS: 48 NIH male mice were randomized into blank group (normal saline), model group (normal saline), dexamethasone acetate group (0.005 g?kg-1), ethanol extract of Radix et Rhizoma Gentianae groups (high-dosage of 10 g?kg-1, medium dosage of 5 g?kg-1 and low dosage of 2.5 g?kg-1). The groups were administered via i.g gtt once a day for five days. ALI model was induced by intratracheal injection of lipopolysaccharide (LPS, 2.5 mg?kg-1) after last treatment. ELISA method was applied to determine the content of prostaglandin E2 (PGE2), interleukin-10 (IL-10) and cycloxygenase-2(COX-2) at 24 h after modeling. RESULTS: As compared with model group, the content of PGE2 and COX-2 in ethanol extract of Radix et Rhizoma Gentianae groups were decreased significantly (P

Objective To investigate the risk factors of gallstone disease in Inner Mongolia populations.Methods A case-control study was conducted in 180 consecutive patients who had undergone cholecytectomy for gallstones in the hospital of Inner Mongolia during December 2010 to December 2011.Another 200 patients (age 19 to 81 years old) with no gallstone disease were enrolled as controls.All the participants completed a questionnaire and took physical or ultrasonographic examinations.Univariate analysis and Multivariate logistic regression analysis were used for data analysis.Results Mean age of the study group and the control group was (51.7 ± 13.2) and (54.6 ± 12.1) years old,respectively.More female patients were found in the study group (130:50,x2 =9.552,P ＜ 0.05).After adjusting age and gender,multivariate logistic regression showed that gallstone disease was significantly associated with higher educational level (OR =7.05; 95％ confidence internal (CI):1.28-38.85),animal viscera intake (OR =12.75,95 ％ CI:4.67-34.82),fried food intake (once and twice a week:OR =9.04,95％ CI:4.67-17.51; twice a week:OR=5.39,95％ CI:1.60-18.21) and dyslipidaemia (OR=2.81,95％ CI:1.49-5.30).Vegetables intake (2-3 times a week:OR =0.28,95％ CI:0.03-2.65 ; 4-5 times a week:OR =0.09,95 ％ CI:0.01-0.80 ; once a day:OR =0.02,95％ CI:0.002-0.19) was inversely associated with gallstone disease.Risk factors of gallstone disease were different by genders.Conclusions Animal viscera or fried food intake and dyslipidaemia may increase the risk of gallstone disease.However,vegetables intake may prevent the development of gallstone disease.

ObjectiveTo confirm the effect of miR-93 inhibitor in glioma cell growth and invasion.MethodsMalignant glioma cells were transfected with miR-93 inhibitor by lipofectamin to downregulate their overexpression of miR-93.Real time-PCR was taken to measure miR-93 expression after transfection.The cell cycle kinetics and cell growth rate were detected by flowcytometry and MTT assay,the cell proliferative ability was evaluated by soft agar assay,and the invasive ability was detected by transwell assay.ResultsThe highlevel expression of miR-93 was downregulated effectively in glioma cells after transfecting the miR-93 inhibitor.Meanwhile,the cell cycle progress was delayed,S phase cells were reduced,the speed of growth was slowed,cloning formation ability was receded,the number of cells through the matrigel was reduced,and invasive ability was significantly repressed.ConclusionDownregulation of miR-93 expression could inhibit the proliferative ability and invasive ability of glioma cells.

Objective: To investigate the effects of lidocaine on impairment of learning and memory function and cholinergic system caused by cerebral microsphere embolism in rats. Methods: Healthy male Wister rats were randomly divided into the following groups. (1) Control group. (2) 600 microsphere group and 900 microsphere group, in which 600 or 900 microspheres were injected into the right internal carotid artery, respectively. (3) 600 treatment group and 900 treatment group, in which 600 or 900 microspheres were injected into the right internal carotid artery, respectively, and lidocaine was given. Water maze tasks were tested for 5 consecutive days from the 7th postoperative day. The rats were then decapitated and regions of cerebral cortex, hippocampus, and striatum were selected. The activities of choline acetyltransferase and cholinesterase and the binding activity of muscarinic receptor were determined. Results: (1) The latency periods were significantly longer in the 900 microsphere group than in the control group and in the 600 microsphere group. (2) The percentages of effective search strategy were significantly lower in the 600 and 900 microsphere groups than in the control group. They were significantly higher in the 600 and 900 treatment groups than in the corresponding microsphere groups. (3) The activities of choline acetyltransferase of cerebral cortex were significantly lower in the 900 microsphere and two treatment groups than in the control group. They were also significantly lower in the 600 and 900 treatment groups than in the corresponding microsphere groups. Those of striatum were all significantly lower in the microsphere and treatment groups than in the control group. (4) The activities of cholinesterase of cerebral cortex were significantly lower in the 900 microsphere group than in the control and 600 microsphere groups. They were significantly higher in the 900 treatment group than in the 900 microsphere group. Those of hippocampus were all significantly lower in the microsphere and treatment groups than in the control group. (5) The binding activities of muscarinic receptor of cerebral cortex were significantly lower in the 900 microsphere and two treatment groups than in the control group. They were also significantly lower in the two treatment groups than in the corresponding microsphere groups. Those of hippocampus and striatum were all significantly lower in the microsphere and treatment groups then in the control group. They were also significantly lower in the 600 or 900 treatment group than in the corresponding microsphere group. Conclusion: Cerebral microsphere embolism caused significant and quantity-dependent impairment of learning and memory function and cholinergic system in rats. Lidocaine alleviated learning and memory dysfunction caused by cerebral microsphere embolism, but further inhibited the parameters of central cholinergic system.

Objective To describe the prevalence and risk factors of suicidal ideation and suicide attempt among community patients and their family members in Beijing.Methods Accidental sampling method was used in this cross-sectional study to select patients and their family members who visited a community healthcare center in Beijing from June to September 2008.The subjects were required to complete essential information questionnaire,Beck Depression Inventory,Beck Anxiety Inventory and Beck Hopelessness Scale.Chi-square test and binary logistic regression were used to learn the risk factors of suicidal ideation and suicide attempt.Results A total of 2791 valid questionnaires were collected,with a response rate of 90.0％.The participants included 1074 males and 1717 females with mean age (36.8±13.1)years old.The one-year prevalence of suicidal ideation and suicide attempt was 2.8％ (77/2791) or 1.1％ (30/2791),respectively.The one-year prevalence of suicidal ideation was significantly different among the subjects with different professions (x2=12.512,P=0.006),negative events (x2=53.287,P＜0.001),family history of suicide (x2=103.922,P＜0.001),family history of psychiatry diseases (x2=20.640,P＜0.001),hopelessness (x2=77.337,P＜0.001),depression (x2=135.918,P＜0.001) and anxiety (x2=70.303,P＜0.001).The one-year prevalence of suicidal attempt was statistically different among the subjects with different professions (x2=7.954,P=0.037),family history of psychiatry diseases (x2=6.257,P=0.003),hopelessness (x2=29.838,P＜0.001),depression (x2=21.352,P＜0.001) and anxiety (x2=10.014,P＜0.001).Multivariate logistic analysis found that the most important risk factors of suicidal ideation were depression (for mild,moderate and severe depression:odds ratio (OR) 2.38,5.55 and 16.21,respectively; 95％ confidence internal (CI) 1.07-5.31,2.31-13.37 and 6.93-37.92,respectively),family history of suicide (OR=1 1.68,95％CI 5.03-27.10),hopelessness (for mild,moderate and severe hopelessness:OR 3.65,4.25 and 5.02,respectively; 95％ CI 1.55-8.56,1.70-10.65 and 1.46-17.26,respectively),negative life events (OR=2.25,95％ CI 1.35-4.45).The most important risk factors for suicide attempt were hopelessness (for mild,moderate and severe hopelessness:OR 1.09,5.58 and 7.62,respectively; 95％ CI 0.36-3.34,2.03-15.30 and 1.50-38.72,respectively),depression (for mild,moderate and severe depression:OR 1.08,0.27 and 3.02,respectively; 95％ CI 0.43-2.75,0.03-2.29 and 1.05-8.75,respectively) and family history of psychiatry diseases (OR=3.00,95％CI 1.07-8.46).Conclusions Hopelessness and depression could increase the risk of suicide behaviors.Family clinicians should be trained to identify such risk tactors and provide appropriate mental health intervention.

This article investigates the effect of regulating wei qi and tonifying brain on insomnia from two aspects. It provides theoretical basis for clinical application of regulating wei qi and tonifying brain. First of all, this method regulates the sleep function to keep the body’s yin-yang balance by regulating wei qi. Wei qi is the defense qi in the body and has close relationship with sleep. Wei qi can regulate sleep by the excitement and depression of Yin and Yang Heel Meridians.
