Recently the research of vaccines and drugs against anthrax is one of hot spots. The efficacy of anthrax vaccines and drugs can't be experimented in human, therefore the testing model is very important. The cell models mainly include CHO and J774A.1. Now, various kinds of animals including mice, rats, rabbits, and nonhuman primates were experimented as animal models. Because the models are different, the results of experiments are significantly different, sometimes they are contrary. Many experiments of Bacillus anthracis in different cell and animal models are reviewed, and the principles of choosing animal models of anthrax are discussed. In order to analyze the different results of experiments in different models, the pathogenesis of Bacillus anthracis and the researching progress of anthrax vaccines and drugs are also simply introduced .

Group A was intervened by acupuncture, chiropractic plus functional exercise of lumbar and gluteal muscles, group B by acupuncture plus chiropractic, group C by acupuncture plus functional exercise of lumbar and gluteal muscles, and group D by chiropractic plus functional exercise of lumbar and gluteal muscles. The four groups were intervened once every other day. The modified Oswestry Disability Index (ODI) score was observed before and after 5 treatment sessions, and the clinical efficacies in the four groups were compared.Result The total effective rates were 100.0% in the four groups, and the inter-group differences were statistically insignificant (P>0.05). The ODI scores in the four groups were significantly changed after treatment and in the 3-month follow-up study compared with those before the treatment (P<0.05). After the treatment, the ODI score in group B was significantly different from that in the other groups (P<0.05). The ODI scores in group A and B in the 3-month follow-up study were significantly different from those after the treatment in the same group (P<0.05). The ODI score in group A was significantly different from that in the other groups in the 3-month follow-up study (P<0.05). The ODI score in group B in the 3-month follow-up study was significantly different from that in group C and D (P<0.05).Conclusion Acupuncture, chiropractic plus functional exercise of lumbar and gluteal muscles is definitely effective in treating postpartum sacroiliac malposition, acupuncture plus chiropractic can produce a significant short-term efficacy and alleviate the symptoms, and functional exercise of lumbar and gluteal muscle can produce an obvious long-term efficacy.

ObjectiveTo observe the dynamic change of mtDNA in rats with lung ischemiareperfusion (IR) injury and the implications.MethodsThe rat model of lung IR injury was made.Thirty-two male SD rats were divided into IR group and control group.Each group was sub-divided into two subgroups.Thirty and 60 min after reperfusion,8 rats of each group were sacrificed; left lungs and whole blood were collected.Histopathological study of lung tissues were performed; wet weight/dry (W/D) weight ratio of the lung was detected; DNA was extracted from whole blood,and mtDNA level in circulation was detected by using real-time PCR; the protein levels of MMP-9 and MCP-1were examined by ELISA.Results(1) As compared with control group,the edema and PMN emigration were more serious in IR group; besides,the W/D ratio was increased progressively in IR groups as compared with control groups respectively (P＜0.01); (2) As compared with control group,the mtDNA in circulation was significantly increased 30 min after reperfusion (P＜0.01),and the same trend was detected 60 min after reperfusion (P＜0.01):(3) There was no significant difference between the two groups in the content of MMP-9 and MCP-1in the lungs 30 min after reperfusion (P＞0.05),but the MMP-9 and MCP-1expression levels were increased 60 min after reperfusion (P＜0.01).ConclusionThe mtDNA expression in circulation was increased in the early stage of lung IR,and the increased expression of mtDNA was earlier than the up-regulation of MMP-9 and MCP-1.Our results indicated that mtDNA may aggravate lung injury through increasing MMP-9 and MCP-1in the lung IR.

ObjectiveTo evaluate the diagnostic performance of bone SPECT and CT fusion imaging in bone metastases from pediatric neuroblastoma.MethodsTwenty-four pediatric patients with neuroblastoma were included in this retrospective study.All patients underwent planar imaging and SPECT integrated with CT.Lesion visibility,diagnostic certainty and diagnostic performance were evaluated with KolmogorovSmirnov test andx2 test.ResultsLesion visibility of SPECT alone,SPECT integrated with CT were significantly better than that of planar imaging ( both H =69.000,P ＜ 0.05 ).SPECT and CT fusion imaging,SPECT alone both detected five more bone lesions than planar bone imaging (77 vs 72).The diagnostic accuracy of SPECT imaging (62.34％,48/77 )was significantly higher than that of planar imaging (45.45％,35/77; x2 =4.416,P ＜ 0.05 ).The sensitivity,specificity and accuracy of SPECT and CT fusion imaging for diagnosing malignant bone lesions were significantly higher than those of planar imaging:82.35％ (42/51) vs 53.19％ ( 25/47),88.46％ ( 23/26 ) vs 40.00％ ( 10/25 ),84.42％ ( 65/77 ) vs 45.45％ (35/77 ; x2 =12.571,14.016,25.667,all P ＜ 0.01 ).The diagnostic specificity and accuracy of SPECT and CT fusion imaging were significantly higher than those of SPECT alone ( 53.85％,14/26 ;62.34％,48/77) (x2 =7.589,9.606,both P ＜0.01 ).However,there was no significant difference of sensitivity between the two methods (x2 =2.942,P ＞ 0.05 ).Diagnostic certainty by SPECT and CT fusion imaging was significantly higher than that by SPECT alone ( H =28.000,P ＜ 0.05 ) and by planar imaging (H =21.000,P ＜ 0.05).ConclusionSPECT and CT fusion imaging can detect more bone lesions in patients with pediatric neuroblastoma.It is helpful for diagnosing bone metastases from pediatric neuroblastoma.

Immunoglobulins ( Ig ) , also called antibodies, are important components in humoral -mediated immunity. Ig can bind with their receptors, called immunoglobulin receptors ( IgR ) , trigger biologic activities respectively. Different sub-types of Igs show different function. And IgRs have been treated as therapeutic targets in inflammation and immunity related dis-eases for many years. This article reviewed the recent progresses in the study of IgR function and its therapeutic role in inflamma-tion and immunity related diseases.

Objective To clarify the diagnostic value of oblique axial scan parallel to the course of the anterior talofibular ligament in magnetic resonance imaging of anterior talofibular ligament in patients with chronic ankle instability. Methods 96 patients with ankle injury who were admitted into our hospital form June 2010 to March 2015 were examed with oblique axial scan beside the routine axial magnetic res-onance imaging examination. The grade of the anterior talofibular ligament injury and confirmed full-length views of the anterior talofibular lig-ament were analyzed by two musculoskeletal radiologists ( with more than 5 years experience) , and associated lesions were also checked. Re-sults The full-length view of the anterior talofibular ligament was checked in 69 patients (71. 8%) through the routine axial view and it was checked in 93 patients (96. 9%) through the oblique axial scan view. Anterior talofibular ligament injury was checked in 71 patients through the oblique axial scan, which was 19 patients more than that through the routine axial. Conclusion An additional oblique axial scan is use-ful in evaluation of anterior talofiibular ligament in patients with ankle injury.

Access of safe, effective, convenient and affordable medical and health care services to the people is set as the goal of public hospitals health services as stated in the "Guidelines for Public Hospitals Pilot Reform". Such a goal, however, can hardly be achieved by mechanism changes within the public hospitals. The input and output of public hospitals rely critically on such factors as the input mechanism, regional pattern of healthcare system, the economic and industrial conditions of the region,payment quota and payment approval procedures of medical insurance. This paper set off from the input compensation mechanism of public hospitals in China and analyzed the input and output characteristics of the hospitals. Furthermore, the paper proposed to establish an input compensation mechanism based on public welfare performance for such hospitals. This provided further reference for improving the management of public hospitals and building a public welfare-oriented operation mechanism of public hospitals.
