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.

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.

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.

Objective:Acute retinal necrosis syndrome(ARNS) is a rare disease with high blinding rate.The surgery of vitrectomy,endolaser photocoagulation and silicone oil injection is considered an effective treatment of ARNS.The study investigated the effect of vitrectomy,endolaser photocoagulation and silicone oil injection treating ARNS.Methods:A consecutive 16 eyes of 16 patients with ARNS were treated with vitrectomy,endolaser photocoagulation and silicone oil injection.The 5 eyes without retinal detachment were photocoagulated from the posterior border of necrosis to the ora serrata.The 11 eyes with retinal detachment were treated with subtotal retinal photocoagulation,air/fluid exchange and silicone oil injection.The follow-up time were 6 months at least,16 months in average.Results:The final best-correcting visual acuity was counting fingers in 3 eyes(18.8%),0.02-0.3 in 7 eyes(43.8%),0.4-0.6 in 5 eyes(31.3%),0.7 in 1 eye(6.3%).The silicone oil was uneventfully removed in 14 patients(87.5%) from 3 to 12 months.No one had a recurrent retinal detachment.Conclusion:There is a favorable effect in ARNS with the treatment of vitrectomy,endolaser photocoagulation and silicone oil injection.

Objective To investigate the distribution and sequence conservation of Hap adhensin encoding gene (hap) in clinical isolates of nontypeable Haemophilus influenzae (NTHi), to screen out and identify the predominant T-and B-cell (T-B) combined antigenic epitopes on Hap protein and to analyze their immunogenicity.Methods Sequence conservation of hap genes in NTHi strains and T-B combined antigenic epitopes were predicted using bioinformatic softwares.PCR was used to amplify the 156 bp segment at 5′-end and the 855 bp segment at 3′-end of hap gene (hap-5′-156 and hap-3′-855) and the amplified products were sequenced.Phage display systems of seven T-B combined antigenic epitopes located on the 55 aa segment at N-terminal and the 285 aa segment at C-terminal of Hap protein (Hap-N52 and Hap-C285) were constructed.Western blot assay and ELISA were performed to detect the antigenicity and immunoreactivity of different T-B combined epitopes displayed by recombinant phage PⅢ protein (rPⅢ).Results Hap protein encoded by the hap gene in NTHi was located on membrane surface.Sequences of the 156 bp segment at 5′-end and the 855 bp segment at 3′-end of hap genes extracted from different NTHi strains were relatively conservative, but many mutations were found in sequences at the middle regions of these hap genes.All of the 56 NTHi strains carried hap-5′-156 and hap-3′-855 segments and shared 92.3％-100％ identities in nucleotide and amino acid sequences of these segements.Hap-N5-24 in the Hap-N52 segment as well as Hap-C4-27, Hap-C28-47, Hap-C114-129, Hap-C150-173, Hap-C200-227 and Hap-C241-267 in the Hap-C285 segment was predicted as the T-B combined antigenic epitope with a higher score and less mutations.Results of Western blot assay and ELISA confirmed that the rPⅢ-displayed Hap-C4-27 and Hap-C150-173 epitopes presented clear hybridization bands with NTHi antisera, and 96.9％ (63/65) and 92.3％ (60/65) of serum samples from children with NTHi infection were positive for antibodies against Hap-C4-27 and Hap-C150-173 epitopes, respectively.Conclusion The gene of hap is widely distributed in clinical isolates of NTHi.Moreover, sequences of the 156 pb segment at 5′-end and the 855 bp segment at 3′-end of hap gene are conservative.Hap-C4-27 and Hap-C150-173 are the predominant T-B combined antigenic epitopes on Hap protein, suggesting that they can be used as epitope candidates for developing multiple antigenic peptide vaccines against NTHi.
