Objective To investigate the role of single nucleotide polymorphisms(SNPs)of ALOXSAP promoter gene in ischemic stroke susceptibility in north Chinese Han population.Methods A total of 220 ischemic stroke patients of north Chinese Han population and 191 healthy controls that had been matched for age and sex were enrolled in this study.Polymerase chain reaction(PCR)and direct sequencing were used for target gene genotyping and SNPs analysis.Association study was performed to analyze the relationship between genotype and phenotype and logistic regression was adopted to adjust the bias of conventional stroke risk factors.Results Three novel SNPs located in the promoter of ALOXSAP gene were found and frequencies of G/A genotype of-499 site, G/T genotype of-290 site and G/G genotype of -190 site were significantly higher in ischemic stroke patients than controls.Meanwhile, three haplotypes consisted of these SNPs were identified to be correlated with ischemic stroke, including a protective haplotype, Hap I(OR O.54, 95% CI 0.408 to 0.715), and two risk ones, Hap Ⅱ(OR 2.91, 95% CI 1.351 to 6.239)and Hap Ⅲ(OR 18.82, 95% CI 2.562 to 138.38).Meanwhile, the frequencies of G/A genotype of-499 site, G/T genotype of-290 site, Hap Ⅱ and Hap Ⅲ were significantly higher in ischemic stroke patients with more severe cerebral atherosclerosis indicated by digital subtract angiography. Conclusion Three novel SNPs in promoter of ALOX5AP gene are closely associated with ischemic stroke susceptibility in north Chinese Han population.

Objective To quantitatively evaluate the left ventricular systolic synchrony in patients with chronic renal failure (CRF) by real-time three-dimensional echocardiography (RT-3DE). Methods Thirty patients with CRF and twenty-five normal subjects were enrolled in this study.The M-mode ejection fraction (M-EF), left ventricular end diastolic internal diameter (LVIDd), interventricular septum diameter (IVSd), left ventricular posterior wall diameter (LVPWd) were obtained on two-dimension. The global and regional volume-time curves were obtained on three -dimensional. The end diastolic volume (LVEDV),end systolic volume (LVESV) and ejection fraction (LVEF) of left ventricule, the time to minimal systolic volume (Tmsv) of 16,12,6-segmental standard deviation (Tmsv16, 12, 6-SD), maximal difference (Tmsv16, 12, 6-Dif) were derived from Qlab software . The above parameters as a percentage of the cardiac cycle with different heart rates between patients were also calculated from the Qlab software, which were Tmsv16, 12, 6-SD% and Tmsv16, 12, 6-Dif %, rspectively. Results The indices of HR, LVIDd, IVSd, LVPWd and LVESV were significantly higher while LVEF was significantly lower in the CRF group than those of the control group (P<0.05 or P<0.01); The indices of systolic asynchrony of Tmsv16,12-SD%, Tmsv16,12-Dif, Tmsv16 ,12 ,6-SD/R-R%,Tmsv16,12,6-Dif/R-R% were significantly larger in the CRF group than those of the control group(P<0.05 or P<0.01). Conclusions RT-3DE provides a simple, intuitional and noninvasive approach to assess the systolic synchrony of all the LV segments simultaneously and LVEF in patients with chronic renal failure.

Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.

Objective To study the prediction value of C-reactive protein (CRP) level to ankylosing spondylitis disease activity score (ASDAS),the most widely used activity score in ankylosing spondylitis (AS).Methods A total of 386 patients with AS were enrolled and divided into 2 groups by CRP≥3.5 mg/L (n =266) and CRP ＜ 3.5 mg/L(n =120).ASDAS-CRP was evaluated in patients with CRP below the normal range (3.5 mg/L) in different subgroups.Three methods were used to test the consistency between ASDAS-CRP and ASDAS-erythrocyte sedimentation rate (ESR).Results The ASDAS-CRP showed a good correlation with the ASDAS-ESR when CRP level was ≥ 3.5 mg/L (r =0.899,P =0.000).In the group of CRP ＜ 3.5 mg/L,ASDAS-ESR showed better consistency with ASDAS-CRP when CRP level was below 1.5 mg/L(intra-class correlation coefficient 0.902;kappa coefficient 0.70).By the evaluation of variant gradient matrix,CRP 1.5 mg/L coincided with disease activity states.Conclusion There is good consistency between ASDAS-CRP and ASDAS-ESR.When CRP level is below the normal range,1.5 mg/L could be a cut-off value to calculate the optimal ASDAS-CRP score.

Objective To explore the epidemiology of different subgroups of respiratory syncytial virus (RSV) in hospi-talized children with acute respiratory infections in Suzhou. Methods RSV antigen in nasopharyngeal secretions specimens ob-tained from 42 208 hospitalized children with acute respiratory infections from January 2006 to December 2012 were detected using direct immunofluorescence assay. RT-PCR was used to differentiate subgroups A and B of RSV from the positive samples which were randomly selected in the epidemic season of different years. Results RSV infection had a seasonal trend. The peak season of RSV occurred between November and following year’s March and the detection rate of RSV was low between May and September. There was difference in RSV positive rates of peak seasons among different years from 2006 to 2012 (χ2=280.09,P<0.01). In 398 RSV antigen positive samples obtained from peak seasons of different years, 80.15%(319/398) were differentiated as subgroup A and 15.83%(63/398) were subgroup B except 16 samples (4.02%). There was significant difference in distribution of RSV subgroups in peak seasons among different years (P<0.01). Subgroup A of RSV was prevalent in most years. Both subgroup A and B were prevalent in peak season of 2008~2009 with lowest positive rate of RSV. In 2009~2010, subgroup B was prevalent. Conclusions From 2006 to 2012 in Suzhou area, the RSV detection rates in the first four prevalent seasons present an increase trend every other year and then sustain a high prevalence in the following two prevalent seasons. Subgroup A of RSV was the predominant pathogen in hospitalized children with acute respiratory infections.

Objective： The current study was designed to evaluate the treatment results of nasopharyngeal carcinoma by conformal radiotherapy. Methods： From September 1997 to February 2000, a total of 41 cases of recurrent nasopharyngeal carcinoma were treated by conformal radiotherapy. Among them, 27 cases were treated by late-course hypofraction conformal radiotherapy with the dose of 20- 24 Gy at 80％ isodose, 4- 7 Gy per time, following routine radiotherapy of 39 Gy/30f/3weeks. Fourteen cases received total-course conformal radiotherapy with the dose of 59.8 Gy/46f/4.6weeks at 90％ isodose. Results： The reference isodose curves conform to the target in three dimensions in conformal radiotherapy. The acute radiation mucositis, cranial nerve paralysis and trismus incidence were similar in two groups, however, in the hypofractionation group 22％ developed necrosis of nasopharyngeal mucosa, 3.7％ developed reduced optic nerve lesion, whereas none of the hyperfractionation group had these complications. The tumor response rate were both 93％ for two groups. Conclusion： Hyperfraction conformal radiotherapy is effective in the treatment of recurrent nasopharyngeal carcinoma and has relatively lower incidence of radiation complication.

OBJECTIVETo compare the clinical efficacy on upper limb motor impairment in stroke between the interactive dynamic scalp acupuncture therapy and the traditional scalp acupuncture therapy.

METHODSThe randomized controlled trial and MINIMIZE layering randomization software were adopted. Seventy patients of upper limb with III to V grade in Brunnstrom scale after stroke were randomized into an interactive dynamic scalp acupuncture group and a traditional scalp acupuncture group, 35 cases in each one. In the interactive dynamic scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (anterior oblique line of vertex-temporal), the middle 2/5 of Dingniehouxiexian (posterior oblique line of vertex-temporal) and Dingpangerxian (lateral line 2 of vertex) on the affected side were selected as the stimulation areas. Additionally, the rehabilitation training was applied during scalp acupuncture treatment. In the traditional scalp acupuncture group, the scalp stimulation areas were same as the interactive dynamic scalp acupuncture group. But the rehabilitation training was applied separately. The rehabilitation training was applied in the morning and the scalp acupuncture was done in the afternoon. The results in Fugl-Meyer for the upper limb motor function (U-FMA), the Wolf motor function measure scale (WM- FT) and the modified Barthel index in the two groups were compared between the two groups before treatment and in 1 and 2 months of treatment, respectively.

RESULTSAfter treatment, the U-FMA score, WMFT score and the score of the modified Barthel index were all apparently improved as compared with those before treatment (all P < 0.01). The improvement in the U-FMA score after treatment in the interactive dynamic scalp acupuncture group was better than that in the traditional scalp acupuncture group (P < 0.05). For the patients of IV to V grade in Brunnstrom scale, WMFT score in 2 months of treatment and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were improved apparently as compared with those in the traditional scalp acupuncture group (P < 0.05, P < 0.01). But, for the patients of III grade in Brunnstrom scale, WMFT score and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were not different significantly as compared with those in the traditional scalp acupuncture group (both P > 0.05).

CONCLUSIONFor the patients of IV to V grade in Brunnstrom scale in stroke, the interactive dynamic scalp acupuncture therapy achieves the superior improvements of the upper limb motor function and the activity of daily life as compared with the traditional scalp acupuncture therapy, and the longer the treatment lasts, the more apparent the improvements are. For the patients of III grade in Brunnstrom scale, the interactive dynamic scalp acupuncture therapy achieves the similar improvement in the upper limb motor impairment as compared with the traditional scalp acupuncture therapy.
