Objective To study the role of pro inflammatory cytokines tumor necrosis factor?(TNF ?),interleukin 1beta(IL 1?),interleukin 6(IL 6) and anti inflammatory cytokines interleukin 4(IL 4),interleukin 10(IL 10),interleukin 13(IL 13) in acute lung injury(ALI). Methods Wistar Rats (200?50g) were randomly divided into the oleic acid(OA) and Lipoplysaccharide(LPS) induced lung injury experimental group and the only OA induced lung injury control group. The LPS(2mg/kg) was injected in rat's tail vein at the 1, 4, 12 and 24 hours after administration of OA(0.2ml/kg, iv). Reverse transcription polymerase chain reaction(RT PCR) were used to detecting the expression of TNF ?, IL 1?, IL 6 and IL 4, IL 10, IL 13 mRNA in the lung tissue of rats in two groups. Results The results showed that the peak expression of TNF ? and IL 1? mRNA at one hour after first hit by oleic acid, and IL 6 mRNA at four hours were observed. Others, such as IL 4, IL 10 and IL 13 mRNA, the highest levels in lung tissue at four hours after lung injury induced by oleic acid. Conclusions The results suggested that TNF ? and IL 1? are presenting early phase of ALI, and that IL 6 played its important role in delayed development. The over expression of anti inflammatory cytokines IL 4, IL 10 and IL 13 may be as a promoters rather than protectors in inflammatory amplification.

Their peak torque with knee flexion and extension was measured under 4 kinds of action of ankle. Results There was significant difference in peak torque neither flexion nor extension among 4 kinds of action of ankle (P>0.05). Conclusion It is unimportant of the state of ankle for knee training.

Hepatitis B is a serious infectious disease worldwide, and hepatitis B virus (HBV) is the direct cause of this disease. In recent years, as an essential part of its evolutionary process, HBV mutation has been extensively studied domestically and globally. However, the study on the conserved sequences in HBV sequences is still in its infancy. In this study, we applied multiple EM for motif elicitation (MEME) algorithm to discover HBV motif and proposed a new metric, conservative index (CI), to carry out phylogenetic analysis based on HBV sequences. Then, the constructed phylogenetic tree was subjected to reliability assessment. The results demonstrated that the new metric CI combined with the MEME algorithm can effectively help to discover motifs in HBV sequences and construct a phylogenetic tree based on them and to analyze the evolutionary relationship between HBV sequences; in addition, the possible ancestral sequences of samples may be obtained by conservative analysis. The proposed method is valuable for the exploratory study on large HBV sequence data sets.

Results After1, 2, 3, 4 times treatment, the VAS score of and treatment group VAS score, the efficacy of lumbar flexion activity of treatment group were significantly better than the control group (t=71.619, 57.166, 56.329, 56.632;72.579, 55.330, 38.418, 25.889, P<0.01);After 1, 2 times treatment, the treatment group lumbar extension activity and flexor activity of treatment group comparison with the control group significantly improved compare with the control group(t=26.372, 22.092, 13.418, 16.373, P<0.01). Conclusion Wanyao-Tingli Manipulation can significantly relieve improve low back pain and improve activity in the treatreatment ofing instability of lumbosacral joint with immediate significant effect.

Objective To evalute the value of spiral CT in diagnosis and treatment of chronic suppurative otitis media.Methods Sixty-five cases including seventy-nine ears underwent the direct axial plane and coronal multiplanar reformation and three-dimensional reconstruction of auditory ossicular chain in chronic suppurative otitis media spiral CT imaging of temporal bone. Results The direct axial plane and coronal multiplanar reformation in diagnosing of the chronic suppurativeotitis media were correspondent,but in showing of the most middle ear structure were difference. Three-dimensional images was superior to axial and coronal MPR images in showing of the change of malleus and incus,the contrary situation in showing stapes. Only 3D image may not select application for definition.The rate of agreement between spiral CT diagnosis by combination of three different imaging methods and definition of chronic suppurative otitis media and operative findings(89.9%～97.5%) were higher, false positive rate(2.9%～6.0%) and false negative rate(0～14.6%) of the CT diagnosis were lower.Conclusion Combination of three different imaging methods(axial images, coronal MPR images and three-dimensional images of the ossicular chain) can improve the value of the spiral CT diagnosis and therapy of chronic otitis media.

Objective To investigate the clinical characteristics of hypertrophic cardiomyopathy (HCM) in the elderly. Methods The clinical characters of HCM in 70 elderly patients were retrospectively analysed. Results Among the 196 identified HCM patients, 70 were elders. Out of them, 7 patients(10.0%) were suspected as HCM according to the clinical symptoms, 29 patients (41.4%)were suspected as other cardiac diseases, 34 (48.3%) were diagnosed HCM due to other reasons. Among the 70 patients, 12 patients(17.1%) had history of cerebrovascular diseases, 54 (77.1%) manifested symptoms after 45 years of age and 4 (5.7%) showed no obvious symptoms. Among them, 18 patients were examined by UCG for two times and HCM was diagnosed at the second time. Conclusions HCM in the elderly is not an uncommon disease. The onset of cardiac symptoms is relatively late in the elderly HCM and frequently misdiagnosed; cerebrovascular diseases are commonly seen in elderly HCM patients.

AIM: To establish the model of systemic inflammatory response syndrome (SIRS)/acute lung injury (ALI) by LPS administration in rats and to measure the content of interleukin-10 massage RNA(IL-10 mRNA) and activator protein-1 (AP-1) activity in order to investigate the anti-inflammatory mechanism.METHODS: Wistar rats were injured with increased dose of LPS to set up the SIRS/ALI model. Reverse transcriptase-polymerase chain reaction(RT-PCR) and electrophoretic mobility shift assays (EMSAs) were used to measure IL-10 mRNA content and the AP-1 binding activity in rat lung, respectively.RESULTS: ①LPS could be applied to simulate SIRS-ALI in rats.②Acute respiratory distress syndrome (ARDS) could be induced under condition of LPS≥6 mg/kg, which was similar to that of the excessive expression of SIRS. ③ LPS may cause the increase content of IL-10 mRNA and AP-1 activity in lung in rat. ④Content of IL-10 mRNA and AP-1 activity were increased significantly under LPS≥6 mg/kg. CONCLUSIONS: ①LPS≥6 mg/kg might cause the SIRS/acute lung injury in rats.②The rats with excessive SIRS/acute lung injury had an obvious increase of transcription of IL-10 gene and upregulated AP-1. ③ Intensified anti-inflammatory mechanism plays a pathological role in SIRS/acute lung injury.
