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.

Objective To explore the effect of state of the ankle on peak torque of knee flexors and extensors. Methods 18 adults in community over 65 years old were included. 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.

Objective To investigate the cognition and attitude towards the elderly family nursing among nurses and college students in Chengde, and analyze its influencing factors. Methods A total of 1000 college students and nurses in Chengde were investigated by self-designed questionnaire about their cognition and attitude to elderly family nursing. Results Nurses' cognition and attitude towards the elderly family nursing was better than nursing college students, medical students were better than non-medical students; and there was no statistical significance about their expectation for government's senior citizen service among different groups. Conclusions More attention should be paid to family members' attitudetowards the elderly home care, and should strengthen the elderly family care through various way.

AIM: To establish an external standard HPLC method for the determination of protocatechuic acid and protocatechualdehyde in Compound Shijiqing Tablets(Folium Ilicis Chinensis, etc.). METHODS:Alltima C 18(5?m, 4.6mm?250mm)was used. The mobile phase was consisted of methanol-1% acetate(18∶82). The flow rate was 1.0mL?min -1. The UV detection wavelength was at 280nm. RESULTS: The two components has good resolution. The liner ranges were in the range of 7.6~127.1?g?mL -1 for protocatechuic acid and in the range of 2.62~43.6?g?mL -1 for protocatechualdehyde with the correlation coefficients 0.9997 and 0.9994, respectively. The average recoveries were 99.9% and 97.5% with RSD 2.1%,2.2%(n=5), respectively CONCLUSION: The method is accurative, reproducible and can be used to control the quality of Compound Sijiqing Tablets.

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.
