OBJECTIVE To investigate the anti- tremor effect and mechanism of baicalein on oxotremorine- induced muscle tremor in mice. METHODS The acute model of muscular tremor was induced by intraperitoneal injection of oxotremorine, and the latency, duration and frequency of muscle tremor in mice were measured immediately; the saliva of mice was measured to reflect the correlation between tremor and peripheral nerve function; the aim of this study was to determine the content of MDA and the activity of GSH-PX, and to investigate the anti-oxidation of mice with tremor model. The activity of acetylcholinesterase (AchE) and acetylcholine transferase (ChAT) can indirectly reflect the level of acetylcholine in the brain. The level of monoamine neurotransmitters in brain tissue was determined by high performance liquid chromatography (HPLC-ECD). RESULTS The animals in the model group appeared obvious tremoring, salivating and erecting and other symptoms. Compared to the model group, there was no obvious inhibitory effect on the administration of each dose. After 7, 14, 21 and 28 d of continuous administration, the latency, duration and tremor frequency of tremor mice were significantly shortened, the levels of acetylcholine were significantly decreased, the changes of DOPAC and DA neurotransmitters in the brain of model group were recovered, regulate the dynamic balance of acetylcholine and dopamine in the brain. CONCLUSION Long- term administration can improve the tremor behavior of mice, the mechanismmay be related to the regulation of neurotransmittersin brain.

Objective To assess the expression and significance of proprotein convertase subtilisin kexin 9 (PCSK9) in patients with rheumatoid arthritis (RA).Methods Sixty-five RA patients and forty-seven healthy controls were recruited in this study.The body mass index (BMI) and serum total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL),lipoprotein a,low density lipoprotein (LDL),very low density lipoprotein(VLDL),apolipoprotein A (ApoA),apolipoprotein B (ApoB) and the ratio of LDL-C/HDL-C were tested.Other parameters included disease activity score 28 (DAS28),rheumatoid factor (RF),anti-cyclic citrullinated peptide (CCP) antibody,erythrocyte sedimentation rate (ESR),c-reactive protein (CRP).Serum PCSK9 level was measured by ELISA and compared between RA patients and healthy controls.Results (1) The serum PCSK9 levels in RA patients were higher than those in healthy controls [(409.36 ±223.52) μg/L vs (292.19 ± 109.79) μg/L,P ＜ 0.05].(2) Compared with subgroup of moderate and low active disease and patients in remission,PCSK9 was significantly higher in patients with highly active disease (P ＜ 0.05).(3) The serum PCSK9 levels were positively correlated with RF,TC,TG,LDL,very low density lipoprotein (VLDL),ApoB,with r values as 0.303,0.490,0.320,0.451,0.319,0.463,respectively (P ＜ 0.05).(4) Multiple stepwise regression analysis showed that DAS28,RF,TC and LDL-C/HDL-C were relevant factors for PCSK9 in RA patients.Conclusions The serum PCSK9 level is elevated in RA patients,which is related to RF,disease activity,TC,TG,LDL,VLDL,ApoB.This suggests that PCSK9 is potentially linked to inflammatory reaction and lipid metabolism in rheumatoid arthritis.

Objective:To investigate the underlying mechanism of histone deacetylase (HDAC) inhibitor FK228-in- duced apoptosis of the prostate cancer cell line DU145.Methods:The inhibitory effect of FK228 on DU145 cell growth and its cytotoxicity were determined by MTT assay;cell cycle arrest was detected by flow cytometry assay;morphological change was observed by Giemsa staining;and defined kinase protein levels were determined by Western blot analysis.Re- suits:FK228 obviously inhibited DU145 cells growth,arrested cell cycle at G_0/G_1 phase,induced cells morphological changes and degraded several kinase proteins,including EGFR,Her2,Raf-1,Src,Cdk4 and IAP member Survivin.The degradation of these kinases blocked Raf-Mek-Erk and PI3K/Akt survival signal pathways,inducing apoptosis.Condu- sion:FK228 may induce DU145 cell apoptosis through depletion of multiple kinase proteins and blockade of survival sig- nal pathways of DU145 cells.

At present ventricular remodeling (VR) is regarded as the main pathological basis of chronic heart failure after acute myocardial infarction (AMI), and preventing VR after AMI is of great importance for the prevention of heart failure. Previously, it has not been paid enough attention to the role of inflammation and autoimmune injury during the process of VR after AMI. This topic was discussed in the paper and the treating strategies with Chinese and Western medicine were also explored.

Adiponectin is an adipokine predominantly synthesized and secreted by adipocytes in the white adipose tissue, and it can lower the blood glucose level and increase free fatty acid oxidation. In the current study, we developed the globular domain of adiponectin (gapM1) to treat type II diabetes. In both flask and fermentor, we cultivated Pichia pastoris expressing recombinant gapM1 and established the purification procedure by using gel filtration and anion exchange chromatography. To evaluate the biological activity of recombinant gapM1, we used rat type II diabetes model fed high-fat diet in combination with low-dose STZ (Streptozocin) induction. We purified 200 mg gapM1 with purity of 96% from 10 liters of supernatant. The recombinant gapM1 significantly lowered blood glucose (34.2%), serum triglyceride (79.6%) and total cholesterol (62.1%) in type II diabetes induced rat. Therefore, the recombinant human gapM1 is successfully expressed in Pichia pastoris and effectively treated type II diabetes in rat models.

OBJECTIVETo observe the effects of blood activating wind dissipating acupuncture (BAWDA) on blood pressure (BP) of prehypertension (PHT) patients.

METHODSTotally 60 PHT patients were assigned to the control group and the acupuncture group according to random digit table, 30 in each group. All patients were intervened by life style. BAWDA was additionally performed in patients in the acupuncture group for 6 weeks (30 times). The improvement of BP after intervened by acupuncture was observed. BP success rates and the proportion of PHT progressing to hypertension (HT) were also observed after 6-week intervention of acupuncture and at 1-year follow-up.

RESULTSSystolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after 6-week intervention in the acupuncture. The BP control rate was 56.7% (17/30 cases) in the acupuncture group vs.10.0% (3/30 cases) in the control group with statistical difference (chi2 = 14.70, P < 0.01). At 1-year follow-up BP success rate was 36.7% (11/30 cases) in the acupuncture group, remarkably higher than that of the control group [13.3%, (4/30 cases)] (chi2 = 4.36, P < 0.05).

CONCLUSIONSBAWDA showed BP regulating roles in a gradually stable decreasing tendency. It also could elevate BP success rate of PHT, and reduce the risk of PHT progressing to HT.
