Objective To study the relationship between activity of thorax and each spinal intervertebral angle in patients with ankylosing spondylitis. Methods Each spinal intervertebral angle of 41 patients with ankylosing spondylitis were measured by Spinalmouse in different postures. And the activity of thorax was measured. Correlation between activity of thorax and shape of spinal were analyzed. Results The activity of thorax positively correlated with the entire lumbar spinal column in flexion (P<0.01), as well as the intervertebral angle of L1/2, L2/3 and L4/5 in flexion (P<0.05), but negatively correlated with the intervertebral angle of L1/2 and L2/3, curvature of the entire lumbar spinal column in upright and the intervertebral angle of L1/2, L3/4, curvature of the entire lumbar spinal column in extension. Conclusion There was a significant relation between activity of thorax and lumbar vertebra motor ability.

Objective To learn the current status of job burnout and influencing factors for nurses from infectious disease hospital.Methods The Chinese version MBI -HSS was used to survey 218 nurses from infectious disease hospital,and linear regression was used to analyze the influencing facters of job burnout.Results A total of 210 questionairs were cocleted.The incidence of severe occupational job burnout was 22.38%,and the score of emotional exhaustion (EE), depersonalization (DP),personal accomplishment (PA)was(22.82 ±9.98),(6.48 ±5.20),and (35.20 ±8.82), respectively.Regression analysis demonstrated that the main influencing factors were entering the isolation ward, opportunity for infectious diseases ,disinfection damage,fear of occupational exposure and concern on family infection(P <0.05).Conclusion The status of job burnout of nurses in infectious disease hospital is not optimistic.There is a positive relationship with the working environment,occupational exposure.Managers need to explore an effective way to ease the job burnout of nurses,and to stabilize the nursing team.

To introduce the writing techniques for structured Abstract of literature review papers based on the knowledge of corpus linguistics,so as to summarize the stylistic,structural,syntactic and lexical characteristics,objectively and systematically.This research will also faci-litate the authors and translators,who have difficulties in writing structured English Abstract,to publish their articles via mastering its stylistic characteristics,writing format and language.

Objective To study the animal toxicity test on skin of the Chinese herbal drugs liquid paste (CHDLP).Methods Acute and multiple times skin stimulation test and skin allergy test were performed on healthy guinea pig by using CHDLP.Results The acute skin stimulation score and intensity score were all zero.Multiple skin stimulation score and pathological examination score were all zero.So were the skin allergy score and the sensiti- zation rate.Conclusion CHDLP is a weak sensitizer and arose no skin stimulation on guinea pig.It's safe when ex- ternal use.

OBJECTIVETo investigate the effects of gambogic acid (GA) on the proliferation inhibition and apoptosis induction in Human lung adenocarcinoma A549 cells in vitro, as well as the regulation of steroid receptor coactivator-3 (SRC-3) to explore the relationship between them.

METHODSThe effect of GA on the growth of A549 cells was studied by MTT assay. Apoptosis was detected by Hoechst 33258 staining. The localization of SRC-3 was determined by confocal laser scanning microscopy. Western blot and RT-PCR technique were applied to assess the expression of SRC-3.

RESULTSGA presented a striking proliferation inhibition potency on A549 cells in vitro, as well as apoptosis induction activity in a time- and dose-dependent manner. The IC(50) value for 24 h was (3.17 +/- 0.13) micromol/L. Overexpression of SRC-3 was found in A549 cells, whereas the SRC-3 protein and mRNA expression levels were significantly downregulated in A549 cells induced by GA in a dose-dependent manner. The location of SRC-3 was situated mainly in the cell nuclei.

CONCLUSIONGA exhibits a potent proliferation inhibition and apoptosis induction in human lung adenocarcinoma A549 cells, which might correspond to the downregulation of the expression of SRC-3. Thus, it promises to be a new target drug for lung cancer treatment.

OBJECTIVETo investigate molecular mechanism of tanshinone II A inducing differentiation and apoptosis in acute promyelocytic leukemia NB4 cells.

METHODNB4 cells were cultured in vitro and treated with tanshinone II A and observed cellular morphology, cell category and the cellular proliferation. DNA microarray technique was used to analyze the gene expression profiles of NB4 cells induced by tanshinone II A.

RESULT92.8% of NB4 cells treated with 0.5 mg x L(-1) tanshinone II A were induced into mature neutrophils, in which myetocytes and melamyetocytes were 27.0%, banded and segmented neutrophits 68.2%. Cell growth were inhibited. cDNA microarray showed the enormously expressed 183 genes including 23 differentiation associated genes, and other interrelated genes.

CONCLUSIONTanshinone II A inducing differentiation in NB4 cells may be via regulation of many kinds of genes, especially differentiation associated genes expression. This partially explained the molecular mechanism of tanshinone II A inducing differentiation.

OBJECTIVETo study the relationship between estrogen receptor beta gene (ER beta) polymorphism and unknown aetiology hypomenorrhea in Southwestern China .

METHODSOne hundred eumenorrhea women were chosen as control group and another 100 hypomenorrhea patients as case group from Southwestern China. Restriction fragment length polymorphism (RFLP) of the Rsa I and Alu I in ER beta gene was analysed. The ER beta gene polymorphism genotype distribution in case group and control group was compared.

RESULTSR allele frequency in case and control groups was 37.5% and 48.5% respectively, the OR was 0.64 (95%CI: 0.42-0.97), P= 0.026. A allele frequency in case and control groups was 18.0% and 11.5% respectively, the OR was 1.69 (95%CI: 0.93-3.09), P= 0.07. RFLP of Rsa I and Alu I in both groups were distributed with polymorphism.

CONCLUSIONERbeta gene polymorphism has a relation with unknown aetiological hypomenorrhea. R allele may be the guard factor, and A allele may be its risk factor.

OBJECTIVETo investigate the relationship between the helicobacter pylori (HP) infection and the genetic instability of mitochondrial DNA (mtDNA) in human gastric adenocarcinoma epithelial cells (AGS).

METHODSAfter treated with extracts of HP11638 (CagA+, VacA+) or Hp11638 mutant strain (CagA+, VacA-), AGS cells were collected, and mitochondrial DNA was extracted and Cox-I, Cox-II, Cox-III, ATPase6, ATPase8 and Cytb genes and the D-Loop region were amplified by PCR and then sequenced.

RESULTSThe mutation rates of the mtDNA in AGS cells were correlated with the extracts of the two HP strains in a concentration- and time-dependent manner. But the mtDNA mutation rate in AGS cells treated with the HP11638 extract was higher than that treated with the Hp11638 mutant extract. Total of 616 mutations in D-Loop region were detected, including 489 point mutations, 81 insertions and 46 deletions. Among them, 70.9% (437/616) belonged to GC to AT and AT to GC transition. Seventeen out of 20 (85%) AGS cells treated with extract of HP had mutations in 303PolyC, 16184PolyC and 514CA regions of mtDNA D-Loop. No mutation was detected in Cox-I, Cox-II, Cox-III, ATPase6 and ATPase8 genes, three point mutations were found in the Cytb gene.

CONCLUSIONHP can cause the accumulation of mutations in mtDNA, in particular, in the D-Loop region, and the VacA participated in the process.

Objective To explore the effect of sequential rehabilitation nursing on upper limb function after complete replacement of forearm. Methods A total of 33 patients from September, 2010 to December, 2013 with successful forearm replacement were selected as the control group, and 32 same patients from January, 2014 to January, 2016 were selected as treatment group. The control group received rou-tine care, while the treatment group received sequential rehabilitation nursing. Postoperative visit was paid to two groups. Their upper limb function was compared with total active motion measurement, strength measurement, sensory assessment and hand function assessment. Re-sults All the indexes were better in the treatment group than in the control group (P<0.05). Conclusion Sequential rehabilitation nursing can effectively improve the upper limb function after complete replacement of forearm.
