Objective To evaluate the safety of dynamic anterior plate fixation for cervical distractive flexion injuries and compare its rigidity between different types of plate design. Methods Twelve sets of cadaveric calf spine were used in this test. All the specimens were made into distractive flexion injury models (C4-C5) ac- cording to Allen's method. After discectomy and grafting, they were randomized into three groups in which Orion, Codman, and Window instrumentations were used respectively. The stiffness of each construct was tested in flexion, extension, lateral bending and axial torsion conditions sequentially. Results Compared with an intact cervical spine, the range of motion (ROM) of an injured cervical spine increased whatever plate was applied. Orion in- strumentation presented stiffness the closest to that of the normal control, except for less torsional stiffness. Codman instrumentation provided stiffness close to that for normal and Orion groups only in lateral bending. Window's was the weakest mad not enough in all kinds of movement. Conclusions Static anterior fixation is the first choice for cervical injuries. Dynamic plate fixation may sacrifice stiffness to some extent, especially when a shifting kind of design is to be chosen.

OBJECTIVETo study on effects of acupuncture at a same point at physiological or pathological state on brain functional imaging.

METHODSElectroacupuncture was given at Neiguan (PC 6) of the healthy senile persons (normal group) and the patients of Alzheimer's disease (AD group), and they were scanned on a 1.5 T MRI scanner and the data of functional magnetic resonance imaging (fMRI) were analyzed by Statistical Parametric Mapping (SPM99). The functional imaging of different brain regions were obtained from both the healthy group and the AD group.

RESULTSBoth the frontal lobe and the temporal lobe were activated in varying degrees by electroacupuncture at Neiguan (PC 6) in the healthy group. However, the frontal lobe, the temporal lobe and the cingulate gyrus as well as the cerebellum were activated in varying degrees and other brain regions were not activated by electroacupuncture at Neiguan (PC 6) in the AD group.

CONCLUSIONAcupuncture at Neiguan (PC 6) can activate functions of different brain regions in the healthy group and the AD group, indicating that acupuncture at Neiguan (PC 6) has different effects on functional magnetic resonance imaging in different functional states.

Objective To evaluate the effects of the chronic Keshan disease's self-management in Liangshan Prefecture of Sichuan Province. Methods According to "The Serf Management Program of Chronic Keshan Disease in Liangshen Prefecture of Sichuan Province", 56 chronic Keshan disease patients were selected in the personalized self-manngemant evaluation under the instructions by endemic disease specialists and the rural doctors. Evaluation was based on changes of indexes such as the clinical symptoms, general health conditions, the electrocardiogram, X-ray, the heart function, etc, before treatment and 3 and 6 months following the treatment. Results Clinical signs and symptoms of the patients were significantly improved 3 and 6 months after the treatment, and the improvement was more obvious 6 months than 3 months following the treatment(P<0.05 or< 0.01). After treatment for 3 months, the patients'electrocardingram and heart function did not show obvious change (X2=0.05,039, P0.05); hut obvious improvements Eexcept X ray results(X2=0.61 ,P0.05)] were seen 6 months after treatment (X2=4.36,16.84, P<0.05 or<0.01). Altogether, among the 56 patients evaluated after treatment for 6 months, none achieved the clinical cure standard, 26 cases(46.3%) showed significant improvement, 17 cases (30.4%) were stable, 5 cases (8.9%) were aggravated,one case (1.8%) lost contact, and 6 cases (10.6%) died. Conclusion The project of the chronic Keshan disease's self-management is suitable for the present situati,on of the endemic regions and can he introduced to many places in our country.

Objective To learn the temporal-spatial distribution and clustering of hand-foot-mouth disease (HFMD)in Xiaoshan in 2014,and to provide reference and basis for prevention and control.Methods The HFMD data of Xiaoshan in 2014 was derived from the China Information System for Diseases Control and Prevention.The vector map was created by Map Info 10.0 on the background of 1∶65 000 zoning map ,extracted village and community geographical position information from Baidu map.At the village level,the spatial autocorrelation analysis and spatial scanning analysis were made using software ArcGIS10.2 and SaTScan9.2.Results In Xiaoshan,the epidemic curve of HFMD in 2014 showed two peaks,during April to July and during September to October.The global spatial autocorrelation Moran's I index was 0.442 7(P<0.001),and the global Getis-Ord G value was 0.003 3,(E(G)=0.002 1,Z(G)=11.82,P<0.001). Local autocorrelation analysis showed that the cluster state was high-high.Ningwei Street had the most hot spots.Five statistically significant HFMD clusters were identified by space-time scan statistics,the most likely cluster was located in Heshang Town,from January 6 to February 4 (RR=23.00,LLR=17.45,P<0.05).Conclusion In Xiaoshan,the major epidemic peak of HFMD in 2014 was from April to July.A positive spatial correlations was found,and the disease showed a distinct regional distribution feature and temporal-spatial clustering.The clusters were observed including the villages and communities of rural-urban continuum and in vicinity of industrial development zone in countryside.

Objective To observe the concentration changes of plasma cortisol ( Cor ) and adrenocorticotropic hormone( ACTH) in preterm infants with respiratory failure receiving ventilation treatment. Methods The 30 preterm in-fants with respiratory failure requiring mechanical ventilation were selected as the preterm group with respiratory failure, and 32 full term infants with respiratory failure in need of mechanical ventilation were selected as the term infant group with respiratory failure, and 52 preterm infants( preterm control group) and 17 full term infants( term control group) were selected as controls. All the cases were chosen from Neonatal Intensive Care Unit of Anhui Province Children′s Hospital during January to December 2014. The levels of plasma Cor and ACTH were measured and analyzed. Results (1) Cor level:on the 3rd day, the level of plasma Cor in the preterm group with respiratory failure was lower than that in the term group with respiratory failure[262. 50(162. 00-332. 50) nmol/L vs 531. 00(244. 75-644. 00) nmol/L], and higher than those in the preterm control group[199. 50(49. 05-388. 95) nmol/L] and term control group[120. 00(43. 90-191. 00) nmol/L], the differences were statistically significant(all P<0. 05). On the 7th day, the level of plasma Cor in the preterm group with respiratory failure was lower than that in the term group with respiratory failure[128. 00(65. 85-244. 00) nmol/L vs 222. 00 (131. 50-377. 85) nmol/L], the difference was statistically significant(P<0. 05). (2) ACTH level:on the 3rd day, the level of ACTH in the preterm group with respiratory failure was higher than those in the other groups[38. 20(25. 18-76. 65) pmol/L vs 24. 60(19. 03-38. 20) pmol/L vs 22. 30(14. 40-40. 60) pmol/L vs 24. 20(13. 90-45. 65) pmol/L], the differences were statistically significant(P<0. 05). On the 7th day, the concentration of ACTH in the preterm group with respiratory failure was lower than those in the term group with respiratory failure[16. 55(12. 78-31. 80) pmol/L vs 29. 85(18. 23-54. 65) pmol/L], and there were statistical differences(P<0. 05). Conclusions The newborns with respiratory failure were in criti-cal stress, the level of plasma Cor in the preterm infants with respiratory failure was lower than that of the term infants with respiratory failure, while the level of ACTH in the former was higher than that in the latter. And when the stress disap-peared, both of the plasma Cor and ACTH recovered to the normal level.

Objective Heart transplantation is an effective treatment of end-stage heart diseases and extending the time of donor heart preservation helps to make up for the shortage of donor hearts. This study was to investigate whether high-pressured mixed gas ( HPMG) of carbon monoxide and oxygen could prolong the time of donor heart preservation and its mechanisms. Methods Forty-eight C57BL/6 male mice aged 4-6 weeks were randomly divided in-to four groups of equal number:control ( the donor heart isolated but not transplanted) , immediate transplantation ( the donor heart transplanted right after isolated) , HTK-preservation ( the donor heart preserved in histidine-tryptophan-ketoglutarate solution for 24 hours after isolated, and HPMG preservation ( the donor heart preserved in an HPMG chamber with the oxygen partial pressure of 3200 hPa and carbon monoxide partial pressure of 800 hPa for 24 hours after isolated) .Another 36 recipient mice aged 6-8 weeks were randomly assigned to receive the donor heart immediately after harvested (n=12), preserved in HTK solution (n=12), or preserved in HPMG (n=12).At 2 hours after transplantation, the status of heart re-beating and cardiac function were compared among different groups of recipient mice.At 24 hours, tissues were taken from the transplanted hearts for examination of pathologic changes by HE stai-ning, detection of the apoptosis of cardiac cells by TUNEL, and determination of the expressions of microtubule-associated protein 1 light chain 3 -Ⅱ(LC3-Ⅱ) and B cell lymphoma/leukemia-2 (Bcl-2) by Western blot. Resul ts The re-beating rates of the imme-diately transplanted and HPMG-preserved hearts were significantly higher than that of the HTK-preserved ones (P<0.05).At 2 hours after transplantation, the cardiac function scores were 2.5 (2.0-2.9), 0.8 (0.5-1.0), and 4.5 (4.0-4.5) in the immediate implantation, HPMG-preservation and HTK-preservation groups respectively, with statistically significant differences between any two groups (P<0.05).The expressions of LC3-Ⅱand Bcl-2 were 2.06 ±0.29 and 0.87 ±0.18 in the HPMG-preserved heart recipients and 1.24 ±0.20 and 2.07 ±0.32 in the immediately transplanted heart recipients, both higher than 0.13 ±0.03 and 0.19 ±0.02 in the controls and 0.16 ±0.06 and 0.26 ±0.08 in the HTK-preserved heart recipients (P<0.05), the Bcl-2 higher in the HTK-pre-served heart recipients than in the controls (P<0.05), and the LC3-Ⅱ expression higher in the HPMG-preserved heart recipients than in the immediately transplanted heart recipients (P<0.05).HE staining showed that cell edema and inflammatory cell infiltration were more obvious in the HPMG-preserved heart recipients than in the controls and immediately transplanted heart recipients but less obvious than in the HTK-preserved heart recipients.The rate of cell apoptosis was dramatically increased in the HPMG-and HTK-pre-served heart recipients ([5.04 ±1.77]%and [26.72 ±5.23]%) in comparison with the controls ([1.08 ±0.56]%) (P<0.01) and immediately transplanted heart recipients ([2.13 ±1.71]%) (P<0.01) but decreased in the HPMG as compared with the HTK-preserved heart recipients (P<0.01). Conclusion High-pressured mixed gas preservation can reduce cold ischemia-reperfu-sion injury of the donor heart, which may be associated with its promotion of autophagy, provision of energy to cells, and apoptosis of cardiocytes in the donor heart.

AIM:To compare the difference between Shuxiong Tablet(Radix et Rhizoma notoginseng,Flos Carthami,Rhizoma Chuanxiong)(SXT) and its effective compounds group(SECG) in anti-inflammatory,relieving pain,anticoagulation,anti-thrombus and myocardial protection.METHODS:We adopted experiments of carrageenan-induced paw edema,hot water shrink trail,clotting time in mice,and thrombus in arteriovenous shut,and pituitrin induced acute myocardial ischemia in rats.RESULTS:Both of SXT and SECG could inhibit the tumefaction,decrease PGE_2 and SOD in inflammatory tissue;enhance the pain threshhold of mice;extend clotting time;inhibit the thrombosis;inhibit myocardial ischemia,significantly decrease CK,LDH,MDA and increase SOD in myocardial tissue.CONCLUSION:SXT and SECG have the same effects on anti-inflammatory,relieving pain,anticoagulation,anti-thrombus and myocardial protection.Further more,their dose-response relationship curves were similar,suggesting that SECG having the main effective components of SXT,could take place of SXT in clinical research.
