Objective The purpose of this study was to describe the effect of behavioral intervention of secondary prevention on stroke. Methods 204 patients with stroke were divided into the observation group and the control group with 102 patients in each group at random. The health records were set up and self-designed scale for assessment of risk factors of recurrence of stroke was used to assess the patients' general conditions. Individual intensified education and behavior intervention were adopted in the observation group. Routine treatment and health education were used in the control group. The collected data before intervention, the third and 6th month after intervention were evaluated. The medication compliance, limbs rehabilitation exercises, bad living style, coming to hospital at regular intervals and recurrence rate of stroke were compared between the two groups. Results The observation group was superior to the control group in the following aspects, the mastering rate of disease knowledge, changes in bad living style and therapy compliance (P<0.01). Conclusions Behavioral intervention of secondary prevention could effectively reduce the recurrence of stroke and improve the living quality of patients.

Objective Henoch-Sch?nlein purpura(HSP)is a common multisystemic vasculitis in children ,but the exact pathogenesis remains unknown. Pentraxin 3(PTX3),a new kind of inflammatory cytokines,has a strong inflammatory effect,and is involved in occurrence and develop-ment of a variety of autoimmune diseases. The objective of this study is to evaluate the expression of PTX3,interleukin-8(IL-8),tumor necrosis fac-tor-α(TNF-α)and high sensitivity C-reactive protein(hs-CRP)in children with HSP,and explore the clinical significance of PTX3 in HSP devel-opment. Methods Thirty-six children(HSP group)and 17 healthy children(control group)were enrolled in the study. Serum levels of PTX3,IL-8 and TNF-α were detected by enzyme-linked immunosorbent assay. Serum hs-CRP levels were measured by automatic biochemical analyzer. Re-sults The serum levels of PTX3,IL-8,TNF-α,and hs-CRP were up-regulated in HSP group compared with the control group(P<0.05). The levels of PTX3,IL-8,TNF-α,and hs-CRP in patients with joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury were significant-ly higher than those patients without joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury(P<0.05). The expression of PTX3 was positively correlated with the expression of IL-8 and TNF-α(r=0.514,0.833,all P<0.05),but there was no correlation between PTX3 and hs-CRP(r=0.292,P>0.05). The expression of PTX3,IL-8,TNF-α and hs-CRP in HSP patients had no gender difference(all P>0.05). Con-clusion The high expression of PTX3 is related to the degree of inflammation in children with HSP. The up-regulated expression of PTX3 may play an important role in pathogenesis of HSP in children.

Objective To construct,express,purify and identify the gene encodi ng major outer membrane protein of Neisseria gonorrhoeae (Porin I, or PI). Metho ds The gene encoding for PI of N.gonorrhoeae was amplified by PCR and cloned int o expression plasmid pGEX-4T-2 to form pGEX-4T-2/PI recombinants. A high lev el expression of GST-PI fusion protein was obtained in GST gene fusion system (GST:glutathione S transferase). The analysis indicated that the expressed pr otein was present predominantly in the insoluble form. Therefore, the induced pr otein was purified by SDS-PAGE, and bands corresponding to polypeptides of GST-PI fusion protein were excised and subjected to electroelution. A dot immunoch romatographic assay was employed to demonstrate whether the purified protein was gonococcal PI specific. Results The pGEX-4T-2/PI expression recombinants were constructed,expressed,purified and identified successfully. SDS-PAGE analysis and dot immunochromatographic assay suggested that the recombinant GST-PI fusio n protein was a 60 000 molecular weight protein andidentical in size to native PI and reacted with anti-PI monoclonal antibody. Conclusion Our results may lead to a potentiality for further study of diagnosti c kits and vaccine for Neisseria gonorrhoeae.

Supercritical fluid chromatography (SFC) meets with great favor due to its high efficiency, low organic solvent consumption, and the specialty for the identification of the isomeric species. This review de-scribes the advances of SFC in targeted and untargeted lipid profiling. The advancement of the SFC in-struments and the stationary phases are summarized. Typical applications of SFC to the targeted and untargeted lipid profiling are discussed in detail. Moreover, the perspectives of SFC in the lipid profiling are also proposed. As a useful and promising tool for investigating lipids in vitro and in vivo, SFC will predictably obtain further development.

As the most commonly used antipyretic and analgesic drug,paracetamol(PA)coexists with neuro-transmitter dopamine(DA)in real biological samples.Their simultaneous determination is extremely important for human health,but they also interfere with each other.In order to improve the conductivity,adsorption affinity,sensitivity,and selectivity of TiO2-based electrochemical sensor,N-doped carbon@-TiO2 double-shelled hollow sphere(H-C/N@TiO2)is designed and synthesized by simple alcoholic and hydrothermal method,using polystyrene sphere(PS)as a template.Meanwhile,TiO2 hollow spheres(H-TiO2)or N-doped carbon hollow spheres(H-C/N)are also prepared by the same method.H-C/N@TiO2 has good conductivity,charge separation,and the highly enhanced and stable current responses for the detection of PA and DA.The detection limit and linear range are 50.0 nmol/L and 0.3-50 μmol/L for PA,40.0 nmol/L and 0.3-50 μmol/L for DA,respectively,which are better than those of carbon-based sen-sors.Moreover,this electrochemical sensor,with high selectivity,strong anti-interference,high reli-ability,and long time durability,can be used for the simultaneous detection of PA and DA in human blood serum and saliva.The high electrochemical performance of H-C/N@TiO2 is attributed to the multi-functional combination of different layers,because of good conductivity,absorption and electrons transfer ability from in-situ N-doped carbon and electrocatalytic activity from TiO2.

A large number of data show that the prevalence rate of alcoholic liver injury (ALI) is increasing year by year, and it has become one of the main causes of death due to chronic liver diseases such as liver cancer and liver cirrhosis. Quitting drinking is the main method for the prevention of ALI in modern medicine, and the main treatment methods include Western medicine with antioxidant and anti-fibrotic effects and nutritional support. However, Western medicine tends to have an unsatisfactory treatment effect and can only alleviate initial symptoms, and severe ALI still requires surgical treatment. Studies have shown that the monomers extracted from natural drugs and foods have obvious preventive and therapeutic effects on ALI, with high safety and easy access. Therefore, this article systematically summarizes the main natural drug and food monomers used for the prevention and treatment of ALI and proposes the idea of the combination of drug and food for the prevention and treatment of ALI from the perspective of paying attention to the whole process of health, in order to explore more effective prevention, health care, and treatment methods and provide ideas for research on the prevention and control of ALI.
