There have appeared many new insulin analogues in recently years. Two of them are rapid-acting insulin analogues(aspart,lispro).The regions between the insulin analog molecules were modified,which have shorter time than regular human insulin in onset of action,peak,duration of acting,and are better in decreasing postprandial glucose and opportunity of hypoglycemia before next meal.The another insulin analogues were galargine and detemir.They were obtained from changing insulin isoelectric point and increasing molecular weight,which lengthen time for disintegration,absorption and action and have little absorption variation and no overt peak.They can simulate physiological base insulin excretion.

Resistant starch is not absorbed in the small intestine.But it can be fermented in the large bowel.Recent studies have confirmed the ability of resistant starch to decrease postprandial blood glucose levels,decrease serum cholesterol and triglyeride levels,and enhance the sensitivity of insulin.As such,resistant starch contributes to preventing and treating metabolic syndrome.

Objective To investigate molecular typing and drug resistance patterns of 98 Klebsiella pneumoniae (K.pneumoniae) isolated from type 2 diabetes patients complicated with maxillofacial infection,to research the virulence and resistance mechanisms.Methods The study was a prospective study that adopted the method of continuous sampling from fixed location,from March 2010 to October 2012.The maxillofacial surgery patients diagnosed with type 2 diabetes complicated with maxillofacial infection were chosen in 7 hospitals in Zhengzhou as the research object,and a total of 431 pus sample were collected continuously,in which 98 strains K.pneumoniae were isolated and identified.The Kirby-Bauer disk diffusion test was conducted in 98 strains to determine the resistance to 19 antibacterial agents.K.pneumoniae chromosomal DNA were digested by restriction endonuclease Xba Ⅰ and analyzed by pulsed-field gel electrophoresis (PFGE).PFGE patterns of K.pneumoniae strains were analyzed using Fingerprinting software.The relationship between the molecular types and resistance phenotype was observed.The extended spectrum β-1actamase-producing K.pneumoniae were screened out by the double disc synergy test (DDST)Polymerase chain reaction (PCR) was used to detect resistant genotypes,serotype and virulence genes.The purified PCR products of resistant genes were cloned and sequenced.Hypermucoviscosity phenotype of all strains were determined by string test.Results Much severer drug-resistance for K.pneumoniae was identified and the result of extended-spectrum beta-lactamase producing rate was 57.1 ％.Ninety-eight strains were dispatched into 13 groups by PFGE.No dominant bands and specific extended-spectrum beta-lactamase DNA bands were found.The results of PCR showed that among the 56 strains of extended spectrum β-lactamase-producing K.pneumoniae,40 were positive for blaSHV (accounting for 71.4％),28 positive for blaTEM (accounting for 50.5％),21 positive for blaCTX-M (accounting tor 37.5％).The sequencing results were as follows:TEM-1,CTX-M-3 and a variety of SHV.Serotype K1,K2,K3,K5,K20,K54 and K57 and 3 kinds of virulence genes were detected,but not in strong toxicity-based.Hypermucoviscosity positive rate was 31.6％ (31/98).Conclusion Much severer drug resistance of K.pneumoniae in this study was identified and resistant mechanism was complex,in which strong toxicity serotype and virulence geues exist,which need more attention from clinical.

Objective To assess the value of serum N terminal pro-brain natriuretic peptide(NT-Pro-BNP) in the diagnosis of congestive heart failure(CHF) and evaluation of cardiac function in children with ventricular septal defect (VSD).Methods Fifty one children were enrolled from March 2004 to March 2005.NT-Pro-BNP was measured by enzyme immunoassay technique.At the same time,left ventricular ejection fraction(LVEF) and left ventricular shortening fraction(LVFS) were detected with echocardiography.Results The data of NT-Pro-BNP were showed but the logarithms of which were normal distribution.The values of NT-Pro-BNP were developed successively along with the severity of cardiac function.But there was no difference between the group of no heart failure and mild heart failure.But the values of LVEF and LVFS had no differences in the control,the mild and the moderate heart failure and the same time all of which beyond the standard of diagnosing heart failure.NT-Pro-BNP could reflect the degree of heart failure or cardiac function (r=0.826).But LVEF and LVFS can not reflect the degree of the cardiac function.Conclusions NT-Pro-BNP can reflect the degree of the cardiac function in VSD,and the degree of the heart failure can be classed by the levels of serum NT-Pro-BNP.But the value of LVEF and LVFS can not reflect the degree of the heart failure in the same disease.

ObjectiveTo compare the therapeutic effect of mininal]y invasive removal of intracranial hematoma and conservative treatment in curing hypertension cerebral hemorrhage of elderly patients.Methods60 patients with hypertension cerebral hemorrhage were divided into two groups.Group A were adopted minimally invasive removal of intracranial hematoma(YL-1 type puncture needle was used into the hematoma edge,and sucked slowly the hematoma), and group B were adopted medical treatment(antihypertensive drugs, dehydration, free radicals and nutrition conservative treatment) ,then clinical therapeutic effect and activity of daily living were observed.ResultsThe hematoma evacuation time in group A (4.5 ± 1.2) d is shorter than in group B (17.0 ± 1.9) d (t = 6.04 ,P ＜ 0.05) ; The rate of neurological function recovery in group A (66.7％) is higher than in group B(93.3％) (x2 = 5.46,P ＜0.05) ; The activity of daily living in group A (80.0％) was better than group B (50.0％) (x2 = 5.93, P ＜ 0.05).The complication rate in group A (30.0％) is lower than in group B (66.7％) (x2 = 8.08, P ＜ 0.05).ConclusionThe therapeutic effect of minimally invasive removal of intracranial hematoma in curing hypertension cerebral hemorrhage was better than medical treatment.

Recent in vitro and in vivo experiments have revealed that ellagic acid and its metabolites can inhibit the growth of digestive system malignant tumor cells by inhibiting tumor cell proliferation,inducing apoptosis,breaking DNA binding to carcinogens,blocking virus infection,disturbing inflammation,angiogenesis and drug-resistance processes required for tumor metastasis.Ellagic acid and its metabolites are potential chemoprevention and therapeutic drugs against human cancers.

Objective To understand the influence of nursing intervention in community on hypertension pa-tients′life style and behaviors.Methods 183 hypertensive patients admitted registered in Donghu Street community were selected for nursing intervention for 18 months, from whom effect evaluation was made through pre -and post -intervention.Results Nursing intervention had significant influence on hypertension patients′life style such as smoking, drinking, salt restriction and exercise (p <0.01).With improvement of notable knowledge on hypertension and its risk factors, control rate of blood pressure and medicine taking compliance all increased significantly (p <0.01), but illegible improvement was found respecting weight control, high fat diet and patients′emotion (p >0.05).Conclusion In some way community nursing intervention can alter hypertension patients′life style and help to improve their health status and quality of life.

Objective To construct Gadd45a expression plasmid and induce its expression in human T cells.Methods Gadd45a was amplified by reverse transcription PCR from human embryonic stem cells,and cloned into the pcDNA3.1 vector.The recombinant plasmid or blank plasmid was transfected into Jurkat cells or normal human CD4+T cells using electroporation,and the expression of Gadd45a was detected by quantitative RT-PCR and Western blot.Results Human Gadd45a expression plasmid was constructed successfully.Gadd45a was overexpressed both in Jurkat cells and normal human CD4+T cells after these cells were transfected with pcDNA3.1-Gadd45a.Conclusion The construction of Gadd45a expression plasmid and induction of Gadd45a overexpression in human T cells lay the foundation for further research on the role of Gadd45a in the epigenetic mechanism.
