Objective Through comparing the similarities and differences between respairing effect on rat’s gastric mucosal lesion by electroacupure (EA) at Meridian of Foot Yangming and Meridian of Foot Shaoyang, to explore the specificity of the correlation between Meridian of Foot and Stomach and the mechanism of the healing effect by EA at meridian of Foot Yangming for curing the gastric lesion. Methods Forty rats were randomly divided into 4 groups:blank group, model group, stomach tunnel group, gallbladder tunnel group. All rats (except normal group) were made model by water restraint stress (WRS). After corresponding experimental process, epidermal growth factor (EGF) and transforming growth factor alpha (TGF-?) of plasma, gastric mucous tissue concentration was detected with radioimmunoassay, and the expression of EGFR mRNA of above tissue was detected by the reverse transcriptase-polymease chain reaction (RT-PCR) method. Results The gastric mucosal lesion index of Foot Yangming group decreased significantly in comparison with that of other groups, while EGF, TGF-? of gastric mucous tissue concentration level of Foot Yangming group was obviously higher than that of model group and gallbladder tunnel group. EA oould up-regulate the expression gastric mucosal EGFRmRNA, and there was a more significant difference in the group by EA at Meridian of Foot Yangming than that in the model group and gallbladder tunnel group. Conclusion The curative effect of EA at points of Meridian of Foot Yangming on the gastric mucosa may be realized by the synthesis, secretion and release of the related EGF family factor, such as EGF, TGF-? and so on. Such special regulation of electroacupuncture on gastric mucosal tissue was related to the gene expression of EGFRmRNA, and that may be further mechanism of the curative effect of EA at points of Meridean of Foot-Yangming on gastric mucosal lesion. There existed corresponding correlation between Meridian of Foot Yangming and Stomach.

The paper analyzes and discusses the necessity of integrating computational thinking into basic computer teaching by combining characteristics of medical undergraduates and the current situation and tendency of basic computer teaching,and states the thought and method of solving problems with the computational thinking by taking mind mapping and program design thought as the teaching cases,in order to cultivate the consciousness and ability of students in constructing problem solutions by taking advantage of the computational thinking.

Objective To explore the expressions of autophagy-related gene Beclin-1 and LC3 in adriamycin induced eardiomyopathy rats,to prnve that autophagy might take part in the development of adriamycin induced eardiomyopathy in rats,so as to provide experimental and theoretical evidence for preventing and treating adriamycin induced cardiomyopathy.Methods Forty-five male SD rats were randomly divided into 3 groups,control groups,ADR group and ADR+3-MA group.The model of adriamycin induced cardiomyopathy rats was established.The tissue sample taken from the left ventricle wall was checked for the morphons of autophagosome by electron microscope. The expressions of Beelin-1 and LC3 of myocardium were detected.Results The morphons of autophagosome in ADR group was significantly increased compared with that in control and ADR +3-MA groups. The expression of Beclin-1 in myocardium of ADR group was significantly inereased compared with that in control and ADR +3-MA groups (P < 0.05).The level of LC3 in myocardium of ADR group was significantly increased compared with that in control and ADR+3-MA groups (P < 0.05).Conclusions Autophagy plays an important role in adriamycin induced cardiomyopathy.

Pender′s health promotion model explains the factors influencing health behaviors, which provides a framework for nursing practice and research. Functional exercise compliance in postoperative patients with breast cancer was in a low level, this article reviewed factors influencing functional exercise among breast cancer survivors through three aspects based on health promotion model and made some suggestions on nursing intervention, to promote the rehabilitation of this population.

Objective To construct a ciaR gene-knockout (ΔciaR) mutant of Streptococcus pneu-moniae ( S. pneumoniae) and to investigate the effects of CiaR in CiaH/CiaR, a streptococcal two-component signal-transducing system, on the expression of genes encoding penicillin-binding proteins ( pbps genes) and cia-dependent small RNAs (csRNAs). Methods Electrophoretic mobility shift assay (ESMA) was per-formed to detect the recombinant CiaR (rCiaR)-binding pbps genes. A suicide plasmid pEVP3ciaR for ciaR gene knockout was constructed and then aΔciaR mutant was obtained through homologous recombination and insertion inactivation of the suicide plasmid, and screening with chloromycin. The mutant was identified using PCR and sequencing analysis. E-test was used to detect the minimal inhibitory concentrations ( MIC) of penicillin ( PCN) and cefotaxime ( CTX) against S. pneumoniae strains. Changes and differences in the expression of pbps genes and csRNAs in theΔciaR mutant and its wild-type strain before and after treatment with 1/4 MIC of PCN or CTX were detected using real-time quantitative RT-PCR. Results The rCiaR could bind to the promoter regions in pbp1a, pbp1b and pbp2b genes of S. pneumoniae. The ciaR gene in ΔciaR mutant was inactivated by insertion according to the results of PCR and sequencing analysis. After treatment with 1/4 MIC of PCN or CTX, the expression of pbps genes at mRNA level ( pbps-mRNAs) in theΔciaR mu-tant was significantly increased (P<0. 05), but the levels of csRNAs were significantly decreased (P<0. 05);whereas a significantly decreased pbps-mRNAs (P<0. 05) and increased csRNAs (P<0. 05) were observed in its wild-type strain. The result of E-test showed that the MICs of PCN and CTX against ΔciaR mutant were increased by 250-fold as compared with those against its wild-type strain. Conclusion The CiaR can enhance the drug resistance of S. pneumoniae to PCN and CTX through down-regulating the expres-sion of PBP1a, PBP1b and PBP2b and up-regulating the expression of csRNAs to inhibit the expression of PBPs.

Biotrickling filter often offers a cost effective and environmentally friendly alternative to conventional air pollutant control technologies,but major problems with clogging of the filters due to a high biomass accumulation will provent it from the industried uses.In this paper,the effect of the high biomass accumulation in an air pollution treatment with a biotrickling filter is discussed.Two parameters with specific surface area with biofilm growth(?_ f ) and the bed porosity with biofilm(?_ f )are used to analyse its principle of accumulation.Finally,some control measures including chemical methods,physical machine-made methods and other control methods are overviewed.

Objective To explore the possible effects of hepatocyte growth factors (HGF) on prevention and therapy of disused gastrocnemius atrophy in rats by observing their effects on the wet weight and contractile function of the gastrocnemius of fixed hind limbs. Methods Twenty-four Wister male rats were randomly divided into a blank group, a contrast group and an experimental group. Their right hind limbs were fixed for four weeks with plastic piaster from metatarsus to 1 cm up the knee. Their knee joint was fixed in 100?flexion and their ankle joint in 60?plantar flexion. Rats in the contrast group were injected with 0. 2 mL of normal saline, and rats in the ex- perimental group were injected with HGF (10 mg/kg, 10 mg/mL). Their whole gastrocnemius of the right hind limb was dissected four weeks later to measure its contractile function and wet weight. Results Compared with the blank group, single maximal contraction, maximal tetanus, and wet weight of the gastrocnemius in the contrast and experimental groups decreased significantly (P＜0. 05), and fields of electric stimulation also decreased signifi- cantly (P＜0. 05). Compared with the contrast group, single maximal contraction, maximal tetanus, and wet weight of the gastrocnemius in the experimental group were significantly superior (P＜0.05), and fields of electric stimulation significantly increased. Conclusion Since after a local injection of HGF, the contractile function and wet weight can be significantly increased, HGF may have a preventive effect on disused atrophy.
