The role of chronic inflammation and autonomic neuropathy in the crucial underlying process con -tributing to the initiation and the progression of various cardiovascular diseases is well established .It is well known that the immune system is innervated by the autonomic nervous system , and the inflammatory reaction and immune reaction are re-gulated by the autonomic nerve system .Vagus nerve depresses inflammatory reaction via cholinergic anti-inflammatory path-way (CAP), while sympathetic nervous system has bidirectional regulation of pro-inflammation and anti-inflammation, which are affected by several factors such as the concentration of neurotransmitters or types of receptors .In this paper , we reviewed different effects of CAP and sympathetic nervous system on cardiovascular inflammatory reaction .Activation of CAP and regaining normal sympathetic function will improve the chronic inflammation in the process of cardiovascular disea -ses.Low-toxic and selective α7nAchR agonist is expected to be applied in cardiovascular diseases to alleviate chronic in -flammation .

The dialysis for three species of poplar stems apoplast was obtained by microdialysis method, and then the concentration of Na+, K+, Ca2+ in the dialysis sample was directly measured by graphite furnace atomic absorption spectrometry ( GF-AAS) . The flow rate of perfusate was 1μL/min and the cut-off molecular weight of probe was 30 kDa. The real-time and non-destructive test technique established for the detection of ion concentration could be applied in research of poplar biochemical physiology. The recovery of the proposed method was 95. 8%-103. 1%. The contents of sodium ion in Populus wutunensis, Populus simonii and Salix matsudana were 1034-1156 μg/L, 1493-1611 μg/L and 1586-1703 μg/L; potassium ion were 1012-1237 μg/L, 941-964 μg/L and 1095-1201 μg/L; calcium ion were 4976-5237 μg/L, 4786-5042 μg/L and 5893-6142 μg/L. The method could provide reliable data for the study of ion concentration changes of plant response to adapt to all kinds of external environment.

BACKGROUND:Cervical Open-door laminoplasty with unilateral mass screw fixation and laminectomy with bilateral mass screw fixation are both procedures that treat cervical spondylotic myelopathy by expanding the space available for the spinal cord. Effectiveness and safety of two operative methods remain unclear. OBJECTIVE:To investigate the biocompatibility of implant and host between open-door laminoplasty with unilateral mass screw fixation and laminectomy with bilateral mass screw fixation to treat multi-segment cervical spondylotic myelopathy. METHODS: Data of 117 patients with multi-segment cervical spondylotic myelopathy (≥ 3 segments) were retrospectively analyzed. Sixty-five cases underwent open-door laminoplasty with unilateral mass screw fixation (laminoplasty group). Fifty-two cases underwent laminectomy with bilateral mass screw fixation (laminectomy group). Clinical outcomes were evaluated by the Japanese Orthopaedic Association scoring system and by recovery rate. Cervical curvature index and cervical range of motion were assessed by X-ray films in both groups. RESULTS AND CONCLUSION:The average folow-up time was 28 months (range 12-59 months) in both groups. No C5 nerve root palsy occurred in the two groups. Japanese Orthopaedic Association scores were greater during final folow-up than pre-fixation in both groups (P < 0.01). No significant difference in Japanese Orthopaedic Association score, recovery rate, and final folow-up cervical curvature index was detected in both groups (P > 0.05). Cervical range of motion was lower during final folow-up than pre-fixation in both groups (P < 0.01). Results confirmed that open-door laminoplasty with unilateral mass screw fixation and laminectomy with bilateral mass screw fixation have similar effectiveness in the improvement of neurological function, relieving pain and reducing complications, but wil greatly reduce the cervical range of motion.

OBJECTIVETo explore the anatomic basis and clinical application of the horn shaped perforator flap pedicled with the angular artery for the reconstruction of midface defect.

METHODS(1) 10 fresh cadavers were perfused with a modified guiding oxide gelatin mixture for three-dimensional visualization reconstruction using a 16-slice spiral computed tomography scanner and specialized software (Materiaise' s interactive medical image control system, MIMICS). The origin and distribution of the angular artery perforator were observed. (2) Between July 2012 and July 2014, twenty-one patients underwent operations for the reconstruction of midface defect. Ten patients had squamous cell carcinoma, nine patients had basal cell carcinoma and two patients had nevus. The flaps' size ranged from 1.5 cm x 3.5 cm to 2.5 cm x 5.0 cm.

RESULTSThe facial artery branches the lateral nasal artery 1 cm from the outside corner of the mouth, subsequently strenches to inner canthus continuing as the angular artery. The angular artery anastomoses extensively with the dorsal nasal artery and the infraorbital artery. All the flaps survived. The patients were satisfied with the final aesthetic and functional results.

CONCLUSIONSThe flap can be designed flexibly and simply with reliable blood supply. The donor sites could be closed directly without skin graft, it is a simple and fast method for the reconstruction of midface defect.

Objective To examine whether the marginal division of the striatum(MrD)is involved in the associative learning and memory function of human brain with the help of functional magnetic resonance imaging(fMRI)technique.Methods Sixteen right-handed normal volunteers participated in a test of paired-word associative learning and memory,while the fMRI data were recorded.Control tasks were performed for the block-design.Statistcs parameter mapping 99 was used to analyze the data and to obtain the activated brain regions.Results When the threshold was set as P＜0.005.using a one-sample T-test,the left occipital lobe and the superior and middle gyrus of the left frontal lobe were activated remarkably during the encoding process of the paired-word associative learning and memory task,with the maximum intensity T value being 13.87 and 9.36.respectively.The left MrD was also obviously activated during this stage(T value was 5.46).But during the retrieval process,the left parietal lobe was prominently activated(T value was 8.73).Conclusion The resuhs of this study reveal that the subcortical structures such as MrD as well as the cerebral cortex are involved in the associative learning and memory of paired-word in human brain.

AIM: To study the expression and the role of ERK1/2 and JNK1/2 of MAPKs pathways in the development of neural tube defects induced by hyperthermia. METHODS: The animal models of golden hamster were produced by hyperthermia. The expression of ERK1/2 and JNK1/2, and levels of their phosphorylation were measured by Western blotting in control group and hyperthermia group. RESULTS: p-ERK1/2 steadily expressed in each control group, and the expression of p-ERK1/2 significantly decreased, which was different from that in the corresponding control group (P<0.05). The activity of p-JNK1/2 increased in hyperthermia group and the amount of p-JNK1/2 increased as compared to control group. The peak appeared at 16 h after exposed to hyperthermia (P<0.05). CONCLUSION: Hyperthermia, which induces a decrease in p-ERK1/2 expression and increases the expression of p-JNK1/2 of MAPKs pathway, results in the unbalance of cell proliferation and apoptosis, and induces neural tube defects.

Objective To determine the population structure of Streptococcus pncumoniae isolates collected from infants with eye infections,including drug resistance,resistance genes, serotypes and molecular types.Methods The susceptibility of 39 isolates to 10 antibacterial agents was tested by K-B disk diffusion and Etest.Latex agglutination test was performed to determine the serotype of the strains,and PCR was carried out to detect macrolides resistance genes mefE and ermB.Molecular types of the 20 strains were determined by multilocus sequence typing (MLST).Results A total of 39 Streptococcus pneumoniae isolates were obtained,in which 30 (76.9％) were resistant to 3 or more antibacterial agents,and no vancomycin,penicillin or cefotaxime resistant strain was found.ermB gene was found in 33 strains and mefE gene was found in 4 strains.Twelve serotypes were found,and the most frequent serotypes were 19 (8/39) and 14 (4/39). Seventeen strains (43.6％) were covered in PCV7 vaccine. The international clone Taiwan19F-14 and Spain23F-1 were found by MLST. Conclusions Streptococcus pneumoniae isolates from infants with eye infections include international resistance clones.The distribution of serotype and molecular type are dispersed, and the clones are sporadic. The isolates are highly resistant to commonly used antibacterial agents.

Objective To determine the distribution and antibiotic resistance of hospital - associated pneu-monia(HAP) in senile patient,and the high risk factors of HAP,pathogenic bacterium and prognosis,so as to instruct the clinic prevention and treatment. Methods Patients with age over 60 years old,who were diagnosed of HAP with confirmed pathogens. Pathogens were identified, then the antibiotic resistance was determined by Kirty-Baucer disk dif-fusion assay. High risk factors of HAP, pathogenic bacterium and prognosis were analyzed by Logistic regression analy-sis. Results The first 10th pathogens of HAP patients were pseudomonas aeruginosa( 16.1% ),staphylococcus au-reus( 14.6% ) ,klebsiella pneumonia( 10.2% ), escherichia coil (8.8%) ,staphylococcus hemolyticus (7.3%). MR-SA accounted for 90% in staphylococcus aureus. The drug resistance of pseudomonas aeruginosa to imipenem was 29.5%. The high risk factors of HAP were acute brain accident, hypoalbuminemia, tracheal intubation or mechanical ventilation, rennal failure,COPD, gastric tube, anaemia,liver disfunction,long length of stay ( all P < 0.05 ). The mor-tality of senile HAP was 29.2%. Conclusion There are high antibiotic resistance and high mortality of HAP in se-nile patients. Measures should be taken to modify the risk factors.
