ABSTRACT
OBJECTIVE@#To observe the effect of five-element acupuncture on the cognitive function repair of migraine patients with depression/anxiety disorder.@*METHODS@#The migraine patients with depression/anxiety disorder (19 cases, 5 cases dropped off) were taken as the observation group, and received five-element acupuncture twice a week for 8 weeks. Healthy subjects (19 cases) were selected by demographic data matching as the control group. The cognitive function was evaluated with the event related potential (ERP) technique, and the latency and amplitude of visual evoked potential P300 were adopted as the observation indexes. The headache days (every 4 weeks), headache intensity [visual analogue scale(VAS) score], and headache impact test-6 (HIT-6) score, Hamilton depression scale (HAMD) score and Hamilton anxiety scale (HAMA) score were used as the observation indexes for curative effect.@*RESULTS@#Before the treatment, latency of target stimulus at Fz [ (417.5±34.3) ms] in the observation group was extended compared with the healthy subjects of the control group [(388.6±42.1) ms, @*CONCLUSION@#There are some cognitive impairments in migraine patients with depression/anxiety disorder. Five-element acupuncture not only relieves headache, anxiety and depression effectively, but also improves the activation level of the frontal lobe. It significantly repairs the impaired cognitive function.

OBJECTIVE： To investigate the effects of Buyang huanwu decoction on the expression of MMPs and TIMPs in cardiac tissue of viral myocarditis （VMC） model mice. METHODS： Male BALb/c mice were randomly divided into control group， model group， positive control group [captopril， 100 mg/（kg·d）]， Buyang huanwu decoction low-dose， medium-dose and high-dose groups [6， 18， 36 g/（kg·d）]， with 24 mice in each group. Except for control group， other groups were given Coxsackie virus B3 once intraperitoneally to induce VMC model. After modeling， control group and model group were given constant volume of normal saline intragastrically； administration groups were given relevant medicine intragastrically； once a day， for consecutive 30 days. The general situation of mice in each group was observed. The day of inoculation was set at 0 d， heart mass to body mass ratio （HW/BW） was measured at 4， 10， 20， 30 d after inoculation. The morphological characteristics of myocardium were observed by HE staining， and the myocardial histopathological scores of myocardium were evaluated. The distribution of type Ⅰ and Ⅲ collagen in myocardium was observed by Abcam picrosirius red staining， and the ratio of type Ⅰ to Ⅲ collagen was calculated. At 30 d， relative expressions of MMP-1， MMP-3， MMP-9 and TIMP-1 in cardiac tissue were detected by Western blotting assay， and the ratio of MMPs to TIMPs was calculated. RESULTS： Compared with control group， mice in model group suffered from irritability， arch back， alleviation of stimulation response， reduction of body mass and even mental depression. Typical inflammatory changes and local interstitial hyperemia were observed in the myocardium， accompanied by a large number of lymphocyte infiltration and distribution of type Ⅰ and Ⅲ collagen. HW/BW （at different time points of 10-30 d）， myocardial histopathological score （at different time points of 4-30 d）， ratio of type Ⅰ and Ⅲ collagen （at different time points of 4-30 d）， the expression of MMP-1 and MMP-9， ratio of MMPs to TIMPs were increased significantly， while the expression of MMP-3 and TIMP-1 were decreased significantly （P＜0.05）. Compared with model group， above symptoms of mice in administration groups were improved to different extents. HW/BW [at different time points of 10-30 d in administration groups （except for 10 d in Buyang huanwu decoction low-dose group）]， myocardial histopathological score （at different time points of 10-30 d in administration groups）， ratio of type Ⅰand Ⅲ collagen （at different time points of 4-10 d in positive control group and Buyang huanwu decoction high-dose group， at different time points of 20-30 d in Buyang huanwu decoction low-dose and medium-dose groups）， the expression of MMP-1 （positive control group and Buyang huanwu decoction high-dose group） and MMP-9 （administration groups）， ratio of MMPs to TIMPs （administration groups） were decreased significantly， while the expression of MMP-3 （positive control group， Buyang huanwu decoction low-dose and high-dose groups） and TIMP-1 （administration groups） were increased significantly （P＜0.05）. CONCLUSIONS： Buyang huanwu decoction can inhibit myocardial fibrosis of VMC model mice by inhibiting myocardial collagen hyperplasia， regulating the expression of MMPs and TIMPs， improving MMPs/TIMPs imbalance.
ABSTRACT
OBJECTIVE: To observe the effect of acupuncture intervention on depressive-like behavior and nuclear factor-κB (NF-κB), inducible nitric oxide synthase (iNOS) and nitric oxide (NO) levels in the prefrontal cortex in chronic stress induced depression rats, so as to explore its mechanism underlying antidepressant effect. METHODS: SD rats were randomly divided into control, model, acupuncture and medication (Fluoxetine) groups (8 rats/group). The depression model was established by chro-nic unpredictable stress stimulation (fasting, water deprivation, cold water swimming, tail clamping, constraining, etc., and solitary raising) for 28 days. Acupuncture treatment was applied to "Baihui" (GV 20) and unilateral "Neiguan"(PC 6) once every other day for 14 days. Fluoxetine (10 mg/kg) was given to rats of the medication group by gavage (p.o.) before every stress stimulation, once every day for 28 days. The animals' behavior was tested by using sucrose intake and open field tests (number of crossings and rearings in 5 min). The expression of NF-κB in the prefrontal cortex was detected by Western blot, and the contents of prefrontal iNOS and NO were detected by ELISA and nitric reductases, respectively. RESULTS: After modeling, the sucrose intake and the numbers of crossing and rearing times were significantly decreased (P0.05). CONCLUSION: Acupuncture treatment can improve the depressive-like behavior of depression rats, which is closely related to its effects in down-regulating the levels of NF-κB protein, iNOS and NO in the prefrontal cortex to reduce brain inflammatory damage.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of SSd on reversing the malignant phenotype of HepG2 cells and to investigate its mechanism in order to prove that SSd is a new choice to prevent and treat HCC.</p><p><b>METHODS</b>HepG2 cells were cultured and treated by different concentration (0 mg/L, 2.5 mg/L, 5.0 mg/L, 10.0 mg/L and 20.0 mg/L) of SSd for 24 h, and treated by 10 mg/L of SSd for 0 h, 6 h, 12 h, 24 h, 48 h and 72h respectively. The cell inhibition rates were measured by MTT assay. Then cells were treated by 10 mg/L SSd for 48 hr in experimental group and treated by no SSd as a control, their morphological changes were observed by contrast phase microscope. The concentrations of ALB and AFP in clear supernatant liquid of cells were detected by radio-immunity and chemiluminescence. The cell migration rates were observed by transwell method, the relative expression levels of p27 mRNA were measured by RT-PCR.</p><p><b>RESULTS</b>The inhibitive effect of 10 mg/L SSd was the most significant among different concentrations ( F = 265.06, P less than 0.01). The shape of HepG2 from experimental group turned into small and round, and their volume ratios of nucleus to plasma decreased. ALB in supernatant liquid of HepG2 was higher ( t = 7.83, P less than 0.05, and its AFP was lower ( t = -10.72, P less than 0.01) as compared to control group. Cells migrated were fewer and p27 mRNA expression of HepG2 was higher in experimental group than that in control group (t = 22.00, P less than 0.05).</p><p><b>CONCLUSION</b>SSd could reverse the malignant phenotype of HepG2 cells. It was suggested that the up-regulation of p27 mRNA expression play an important role in the differentiation of HepG2 cells treated by SSd.</p>

<p><b>OBJECTIVE</b>To study the frequency distribution in polymorphism of the apoprotein B 3' variable number tandem repeat (ApoB3'VNTR) and influence factors on hyperlipemia in civil aircrew.</p><p><b>METHODS</b>ApoB genotypes were determined by PCR technology and agarose gel electrophoresis. The blood lipids were measured by routine kits. Personal information of flight personnel was collected by questionnaire.</p><p><b>RESULTS</b>Prevalence of the total dyslipidemia (49.5%) and overweight (55.6%) of flight personnel were much higher than that of domestic general population (29.2% and 49.1%) respectively (P < 0.05). There were 16 alleles and 54 kinds of genotypes of ApoB3'VNTR in the 682 flight personnel. The frequency distribution of alleles and genotypes of aircrew in the two air companies had same trend, which was different from the general population. The frequency of the homozygote was 76.54%, which was much higher than that of the other peoples home and abroad (21.50%). The frequency of the big allele (VNTR > or =39) in hyperlipemia groups were higher than that of normal groups. By analysis of co-variance, the body mass index (BMI), low density lipoprotein (LDL) and the total cholesterol(TC) increased with the cumulate flight hours (P < 0.05). In multivariate logistic regression analysis, the BMI was the only factor influencing blood lipids, and the cumulate flight hours was only factors affecting the BMI. Taking the cumulate flight hours logarithm as the independent variable(X), and the BMI as dependent variable(Y), the linearity equations was: Y = 2.730X + 13.584 (R2 = 0.159, P < 0.01).</p><p><b>CONCLUSION</b>There are perhaps special genetic characteristics in the polymorphism of the ApoB3'VNTR in the aircrew. The big allele is correlated with the hyperlipemia. The flight burden not only directly affects the BMI and blood lipids levels, but also it can indirectly affect the lipids levels by BMI.</p>
