Objective As the genome sequence of Campylobacter jejuni is a hypervariable sequence, the peblA gene sequence of Campylobacter jejuni Pen∶19 was sequenced and the peblA gene conservative was identified. To construct the eukaryotic expression recombinant plasmid of the peblA gene of Campylobacter jejuni Pen∶19 . Methods Total DNA of Campylobacter jejuni Pen∶2, Pen∶8, Pen∶19 and Pen∶21 as templates respectively, peblA gene DNA with KpnⅠ and EcoRⅠ sites was amplified by PCR using the same primer and the PCR product of Pen∶19 was sequenced. Because most close association with Guillain-Barre syndrome, the PCR product of Pen∶19 was selected as target gene and cloned into pcDNA3.1(+) and constructed the recombinant plasmid that was identified by endonuclease digestion and PCR and confirmed by sequencing. The recombinant plasmid was then transfected into mammalian cell COS-7 for expression. The transient expression was investigated by RT-PCR. The expression of peblA gene in the culture supernatant of positive clones was analyzed by ELISA. Results The peblA gene sequence of Campylobacter jejuni Pen∶2 and Pen∶19 was identical. The target gene was amplified from COS-7 cells transfected with recombinant plasmids by RT-PCR. PEBl protein could express in the culture supernatant in the transfected COS-7 cells by ELISA. Conclusion The peblA gene of Campylobacter jejuni was conservative. The recombinant plasmid was constructed and expressed in COS-7 cells successfully. The results obtained lay the foundation for research on development of Campylobacter jejuni DNA vaccine.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

OBJECTIVETo investigate the resistant effect of houttuyfonate sodium (SH) combined with imipenem (IMP) against Pseudomonas aeruginosa (Pa) biofilms.

METHODThe two-fold dilution method was used to examine the minimum inhibitory concentration (MIC) of the tested drug. The crystal violet staining was applied to detect the effect of the combination of 1/2MIC, 1MIC, 2MIC of SH, single IMP, 1/2MIC of SH and IMP of various concentrations on the clearance rate of adherent bacteria, growth of biofilms and alginate production. Fluorescein diacetate (FDA)-propidium iodide (PI) doubling staining assay was employed to observe the bacterial viability and morphological changes after membrane dispersion of each drug group.

RESULTSodium houttuyfonate could enhance the effect of IMP against pseudomonas aeruginosa biofilms. Particularly, the combination group with the concentration of 2MIC showed the highest effect, with P < 0.001 compared with the negative control group. The above results were proved by the bacterial viability and biofilm morphology under fluorescence microscope.

CONCLUSIONAfter being combined with imipenem, sodium houttuyfonate shows a higher effect against biofilms. It is expected that the combination of the two drugs could improve the clinical efficacy of associated infections.

Aim & methods The antagonism of L-dicentrine to contraction of isolated porcine coronary artery strips induced by 5-HT KCl and Ca2+ was observed with U-135 electrophsiological recorder.Results The contractions induced by 5-HT KCl and Ca2+ after high K+ depolarization in the strips of porcine coronary artery were markediy inhibited by L-dicentrine.L-dicentrine significantly depressed maximal response and caused rightward displacement of the dose -response curve. Showing a non-competitive antagonism. In Ca2+ free solution,L-dicentrine inhibited 5-HT-induced contraction of porcine coronary artery,which is dependent on Ca2+ relesed from intracellular store. After Ca2+ concentration in bath solution was restored,L-dicentrine did not influence the contraction of porcine coronary artery depending on extracellular Ca2+.Conclusion L-D have significant relaxation on porcine coronary artery ,which possibly has 5-HT receptor and histamine receptor.

Objective To study the bioavailability and bioequivalence of erythromycin ethylsuccinate granules in healthy male volunteers.Methods In a randomized two-period crossover study,20 healthy male volunteers received single 500 mg test and reference formulations of erythromyein ethylsuccinate granules.The plasma concentrations of erythromycin were assayed by microbiological method.Results The parameters of test and reference preparations were as follows:T_(max)(0.86?0.22)and (0.80?0.13)h,C_(max)(2.13?0.64)and(2.16?0.61)mg/L,t_(1/2)(2.04?0.2)and(1.97?0.4)h,AUC_(0-t)(4.96?1.73)and(4.63?1.52)mg?h/L,respectively.There was no significant difference between the two preparations.The rela- tive bioavailahility of the test granules was(109.1?22.8)%.Conclusions The two preparations of erythromycin ethylsucci- nate granules are bioequivalent.

Objective To explore the high risk factors of metabolic syndrome(MS) in obese children with acanthosis nigricans.Me-thods Body mass index(BMI),blood lipid including triglyeride(TG) and cholesterol(CHO),low density lipoprotein-cholesterol(LDL-C),blood pressure,the level of fasting blood glucose(FBG) and 2 h after oral glucose tolerance test blood glucose(OGTT 2h BG) and the level of fasting insulin(FINS) and 2 h after oral glucose tolerance test insulin (OGTT 2h INS) and homeostasis model appraisal insulin resis-tance index(HOMA-IR) were measured and compared between 25 obese children with acanthosis nigricans[male 15,female 10;aged 8.4-16.0,mean 10.6 years old,weight (72.11?17.66) kg;height (155?14) cm]and 32 normal healthy children[male 18,female 14;aged 7.6-15.8,mean 9.8 years old]in department of pediatric during 1 year.HOMA-IR were also analyzed.Ultrasonic inspections for liver were performed in those children.Results BMI,TG,LDL-C and blood pressure in the obese group were significantly higher than those in the normal control group(Pa0.05).Eighty-four percent of patients in obese children with acanthosis nigricans were diagnosed adiposis hepatica by ultrasonograph.Conclusions The increasing BMI,insulin resistance,blood lipid disorder and blood pressure increase in obese children with acanthosis nigricans are the high risk factors of MS,the close followed-up and treating this kind of obese children can acquire MS early and be helpful to postpone the progress of diabetesⅡ and cardiovascular diseases.

Objective To investigate the pathogenesis of peripheral blood mononuclear cells(PBMC) nuclear factor kappa-?B(NF-?B) in children with primary nephritic syndrome(PNS) and the effect of astragalus on the activity of NF-?B.Methods Twenty-five children with PNS and 20 normal children were studied.Isolated PBMC were separated from 5 mL venous blood in asepsis condition.NF-?B stimulator,NF-?B inhabitor and astragalus were added into the different tubes of PBMC,respectively.The nuclear protein was extracted from the pellets and the optical density(A) values of nuclear protein was measured by enzyme-linked immunosorbent assay(ELISA).Results The activity of PBMC NF-?B in PNS group was higher than that in normal group(P0.05).Astragalus could decrease the activity of PBMC NF-?B which had been stimulated by interleukin-1?(IL-1?)(P
