Influenza (simply as the flu), a kind of acute respiratory infection, is a commonly-seen contagious disease in human, wild birds, swine, horse and other fowl. Its onset is soon, infects quickly and spreading wide. It is a great danger to people's lives. There have been epidemic records of influenza in each century since the 6th century, among which the 1918's caused the most severe consequence. This article contains three aspects. They are naming and classification of flu, epidemic history of flu, Avian Influenza and Swine Influenza. The progress in diagnosis, treatment and prevention on flu are also reviewed. The main purpose of this research is to profoundly reconsider the relationship between human and nature, human and animal as well as human and environment. We need to work hard to reach an ideal harmonious state.

Objective: To observe the changes in neurotrophic factors and their receptors in the lumbar spinal cord of age-increasing rats (1, 3, 6, 12, 18 and 24 months), and to investigate their correlation with age increasing. Methods: The expression of neurotrophic factors and their high receptors in the lumbar spinal cord of rats were measured by immunohistochemistry and western blot. Nissl staining was used for detecting the number of survival neurons. Results: The expression of nerve growth factor (NGF) and its receptor TrkA, brain derived neurotrophic factor (BDNF) and its receptor TrkB, and gliocyte derived neurotrophic factor (GDNF) in lumbar spinal cord of rats showed changes in relation to the age increasing. Their expression was lower at the age of 1 month, reached the peak in 6-month-old rats, and decreased significantly at the age of 24 months, in which the decline of GDNF was more obvious. The number of survival neurons in lumbar spinal cord kept at a high level from 1 to 6-month-old rats, then decreased gradually, and reached the lowest level at the age of 24 months. Conclusion: The expression of neurotrophic factors and their receptors shows changes with age increasing, decreases in aged rats especially, which may be one of the mechanisms involved in spinal cord aging.

Objective To investigate whether conventional protein kinase C (cPKC) II- interacting collapsin response mediator protein-2 (CRMP-2) could provide neuroprotection against cerebral ischemic (I) injuries. Methods Male BALB/c mice were randomly divided into normoxic control (Nor), HPC, Nor+Sham, HPC+Sham, Nor+I and HPC+I groups (n=6 per group). Using our HPC and MCAO mouse models, we applied immunoprecipitation, two-dimensional electrophoresis and mass spectrometry to characterize cPKC II-interacting proteins and combined with SDS-PAGE and Western blot to quantitatively analyze CRMP-2 phosphorylation and degradation levels in the brain of mice after HPC and MCAO. Results Proteomics analysis revealed that the expression levels of 10 cPKC II- interacting proteins changed obviously in cerebral cortex of HPC mice when compared with Nor group. One of these proteins, CRMP-2 protein level increased in particulate fraction and decreased in cytosolic fraction of cerebral cortex of HPC mice. CRMP-2 phosphorylation level in ischemic core (Ic) of cerebral cortex decreased significantly (p<0.05, n=6) as compared with that of Nor+sham group, but CRMP-2 phosphorylation levels in HPC+I group increased significantly compared with that of Nor+I group (p<0.05, n=6). In ischemic cortex, CRMP-2 degradation (proteolysis) was observed as the appearance of 55-ku breakdown products (BDP). However, the CRMP-2 degradation level, BDPs products decreased significantly in penumbra (P) of ischemic cortex from HPC+I group when we compared with that of Nor+I group (p<0.05, n=6). Conclusion CRMP-2 was involved in attenuating the decrease of CRMP-2 phosphorylation in ischemic core and inhibiting its degradation in penumbra of cerebral cortex of mice thereby to lessen the ischemic injuries.

Objective To investigate the effects of Ligustrazine on TNF-α-induced TGF-β1 and CTGF expressions in human peritoneal mesothelial cells (HPMCs). Methods HPMCs were isolated from human omenta by trypsin digestion method and subcultured. Then, the HPMCs were divided into control group, TNF-α-induced (1 μg/L) group and TNF-α-induced plus low-, medium- and high-dose Ligustrazine (10, 20 and 40 mg/L Ligustrazine respectively) groups. The viability of HPMCs was measured by MTT assay. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expressions of TGF-β1 and CTGF mRNAs in HPMCs. Proteins of TGF-β1 and CTGF in culture supernatants were measured by enzyme linked immunosorbent assay (ELISA). Cell protein concentration was measured by trace bicinchoninic acid (BCA) method to correct the ELISA assay results. Results Ligustrazine could significantly decrease TNF-α-induced TGF-β1 and CTGF expressions in a dose-dependent manner both in protein and gene levels (P<0.05). In addition, medium- and high-dose Ligustrazine injection could significantly ameliorate the viability of HPMCs inhibited by TNF-α (P<0.05). Conclusion Ligustrazine could inhibit expressions of TGF-β1 and CTGF in HPMCs cultured under inflammatory conditions.
