Aim To investigate the protective effects of ginsenosides ( GS) on reactive oxygen species-induced oxidative damage in mouse spermatogonial cells. Meth-ods Mouse spermatogonial cell oxidative stress model was established and the attenuating effects of ginsen-osides on germ cell oxidative damage were evaluated by determination of cell viability,malondialdehyde( MDA) formation,superoxide dismutase ( SOD) activity and glutathione ( GSH) level. Results The exposure to hypoxanthine/xanthine oxidase ( HX/XO) induced an elevation in MDA,while a decrease in germ cell viability,SOD activity and GSH level. However,supplementation with GS ( 10 mg?L -1) restored HX/XO-induced decrease in cell viability,SOD activity and GSH level and HX/XO-induced increase in MDA formation. Conclusion GS may exert antioxidant activity to attenuate reactive oxygen species-induced oxidative damage in mouse spermatogonial cells.

OBJECTIVEWith functional magnetic resonance imaging (fMRI), cerebral function imaging of acupuncture and sham acupuncture at Taichong (LR 3) in patients with essential hypertension (EH) was observed to analyze central mechanism of Taichong (LR 3) to treat EH.
METHODSEighteen EH patients were divided into a twisting acupuncture group (10 cases) and a sham acupuncture group (8 cases), which were treated with twisting manipulation and sham acu- puncture at right Taichong (LR 3), respectively. The treatments were both given with 30-second manipulation and 30- second interval for totally 5 min. During the acupuncture, fMRI was adopted to scan the cerebral function imaging of EH patients on resting state, and the acquired data were analyzed with SPM2 module in Matlab software.
RESULTSAcupunc- ture at Taichong (LR 3) in EH patients mainly increased opposite-side oxygen consumption, which generally activated left anterior cingulated gyrus (BA 32), left inferior parietal lobule (BA 40), left inferior temporal gyrus (BA 19), left middle temporal gyrus (BA 37) and right anterior central gyrus (BA 6). The activated areas were related to motor, vision and cognition of emotion. Stimulation region of sham acupuncture mainly included right anterior cingulated gyrus (BA 24), left inferior parietal lobule (BA 40) and left inferior frontal gyrus (BA 7).
CONCLUSIONThe central mechanism of Tai- chong (LR 3) on antihypertensive effect and symptom improvement is not in thalamus and medulla that are traditionally believed to control blood pressure. Taichong (LR 3) could activate anterior cingulated gyrus to regulate parasympathetic nerve and lower blood pressure, and through anterior cingulated gyrus, the connection with the surrounding areas is strengthened to improve the cognitive impairment caused by long-term hypertension.

As a classic eye movement method, electrooculogram (EOG) has been extensively used in many applications. There are many different types of eye movements and artifact in the EOG signal. Noise attenuation and signal separation have received special attention in the EOG research. In this paper, we introduce a novel Linear-nonlinear combinational filter based on weighted FIR-median-hybrid (WFMH) with the characteristic of the EOG signal. The result of the simulation shows that this filter has the property of removing random noise more efficiently when preserving sharp edges. Finally, it is shown that the new filter is effective in separating saccadic and eye blink in the EOG signal.

Objective: To analyze the relationship between the serum levels of low density lipoprotein cholesterol (LDL-C) and achilles tendon thickness (ATT).
Methods: We studied 154 patients with high serum level of LDL-C (LDL-C≥3.37 mmol/L) from 2014-03 to 2015-03, the patients were at (18-75) years of age. According to《Guidelines on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults 2007》, the patients were divided into 2 groups:Borderline high LDL-C (3.3-4.12 mmol/L) group n=50 and High LDL-C (≥4.14 mmol/L) group, n=104;in addition, there was a Normal control group (LDL-C<3.37 mmol/L), n=51. ATT values were measured by standard digital radiography and the results were compared among 3 groups;the relationship between serum levels of LDL-C and ATT was studied.
Results: ATT levels in High LDL-C group (9.42 ± 3.63) mm was higher than Borderline high group (8.24±1.73) mm and Normal control group (6.05±0.28)mm, all P<0.05. The liner correlation coefifcient of serum level of LDL-C and the mean ATT was (r=0.346, P<0.001).
Conclusion: Our preliminary research showed that the higher serum level of LDL-C associated with thicker ATT, they had positive correlation. This phenomenon should be further conifrmed by large sample and multi-center investigation.

OBJECTIVE:
To observe the effect of intrathecal injection of nuclear factor-κB (NF-κB) inhibitor of pyrrolidine dithiocarbamate (PDTC) on pain sensitivity thresholds and the expression of spinal cord CX3C chemokine receptor 1 (CX3CR1) in monoarthritis (MA) model in rats.
METHODS:
Forty-eight Sprague-Dawley rats were randomly divided into 4 groups (12 each) after successful intrathecal catheterization: (1) sham operation with physiological saline group (the sham group); (2) MA with normal saline group (the MA group); (3) 10 μL 100 μmol/L PDTC before MA (the PDTC pre-treatment group); (4)MA before 10 μL 100 μmol/L PDTC (the PDTC post-treatment group). Normal saline or PDTC was injected 5 d after the intrathecal catheterization. Pain sensitivity thresholds were measured in the 4 groups before and after the intrathecal injection at different time points. Rat monoarthritis model was subsequently built by injecting complete Freund's adjuvant (CFA) into the left ankle joint of the rats. On day 3 after the intrathecal injection, expression of microglia in the L₅ spinal cord segment was observed by immunohistochemical method, and the lumbar segments L₄-L₅ of spinal cord were taken to perform RT-PCR to examine the expression of NF-κB mRNA and CX3CR1 mRNA.
RESULTS:
Compared with the MA group, the pain sensitivity thresholds in the sham group, the PDTC pre-treatment group and the PDTC post-treatment group at each time point after the intrathecal injection increased significantly (P<0.05), while microglia in the L₅ spinal cord segment decreased significantly (P<0.05) and expression of CX3CR1 mRNA and NF-κB mRNA in the lumbar segments L₄-L₅ of spinal cord decreased significantly (P<0.05).
CONCLUSION
The hyperalgesic effect of the CFA-induced model of monoarthritis can be relieved by intrathecal injection of NF-κB inhibitor PDTC. Its mechanism is possibly related to NF-κB signal pathway which is involved in the formation of inflammatory pain through regulating CX3CR1 expression.
