Objective To analyze the antibiotic susceptibility, ESBL genotype of clinical Klebsiella pneumoniae strains isolated from People′s hospital and facilitate the control of resistance spread. Methods Identification and antibiotic susceptibility tests of 1 205 strains from 2001 to 2007 were done by VITEK-2 system.The antibiotic susceptibility results were analyzed by whonet5.3.The ESBL gene was detected by PCR and the Chi-square test was used for statistical analysis.Results The rate of ESBL-producing strains in klebsiella pneumoniae has increased from 2001 to 2007[18.8% (40/213) in 2001, 20.9% (53/253) in 2002, 32.8% (42/128) in 2003, 33.6% (45/137) in 2004, 36.6% (60/164) in 2005, 45.3% (68/150) in 2006 and 45.6% (73/160) in 2007].The SHV gene was the most dominant in ESBL genotypes.There were 83.3% (50/60) ESBL strains in 2005 with SHV gene, 82.3%(56/68) in 2006 and 83.6%(61/73) in 2007.The rated of strains with CTX-M gene were increasing.There were 26.7%(16/60) ESBL strains with CTX-M gene in 2005, 36.7%(25/68) in 2006 and 54.8%(40/73) in 2007.The isolates with more than one type of ESBL gene were increasing.There were 45%(27/60) ESBL strains in 2005 with two types of ESBL gene, and no one had more than two types of ESBL gene in that year.There were 47.9%(35/73) ESBL strains in 2007 with two types of ESBL gene.In 2007 there were 9.6%(7/73) and 2.7%(2/73) ESBL strains with three types and four types of ESBL gene respectively.There was a statistical difference between the antibiotic resistance rates of cefotaxime, ceftriaxone and ceftazidime in SHV-gene-phore strains (χ2=13.22, P＜0.01).The strains with SHV gene were more resistant to cefotaxime than ceftriaxone and ceftazidime.There also was a statistical difference of the antibiotic resistance rate of cefotaxime, ceftriaxone and ceftazidime between strains with TEM gene (χ2=9.91, P＜0.01) and CTX-M gene (χ2=34.84, P＜0.01) respectively.None of the strains with CTX-M gene was sensitive to cefotaxime, and they were more resistant to ceftriaxone than ceftazidime.The strains with TEM gene were more resistant to cefotaxime than ceftriaxone and ceftazidime.There were statistical differences of the antibiotic resistance rate to cefotaxime (χ2=29.65, P＜0.01), ceftriaxone (χ2=20.26, P＜0.01) and ceftazidime (χ2=20.26, P＜0.01) between the strains with SHV gene only and strains with SHV and CTX-M gene concurrently.There were also statistical differences of the antibiotic resistance rates to cefotaxime (χ2=11.01, P＜0.01), ceftriaxone (χ2=9.93, P＜0.01) and ceftazidime (χ2=7.01, P＜0.01) between the strains with SHV gene only and strains with SHV and TEM gene concurrently.The antibiotic resistance rates to cefotaxime (χ2=11.54, P＜0.01), ceftriaxone (χ2=17.58, P＜0.01) and ceftazidime (χ2=14.11, P＜0.01) were statistically different between the strains with SHV gene only and strains with SHV and OXA gene concurrently.The antibiotic resistance rates to ceftazidime (χ2=23.61, P＜0.01) were statistically different between the strains with CTX-M gene only and strains with SHV and CTX-M gene concurrently. There was no statistical difference in antibiotic resistance rates to cefotaxime (χ2=3.55, P＜0.01) and ceftriaxone (χ2=3.35, P＜0.01) between the strains with CTX-M gene only and strains with SHV and CTX-M gene concurrently. The antibiotic resistance rates to ceftazidime (P=0.01) were statistically different between the strains with only TEM gene and strains with SHV and TEM gene concurrently, and there was no statistical difference of the antibiotic resistance rates to cefotaxime (P=0.29) and ceftriaxone (P=0.26) between the strains with TEM gene only and strains with SHV and TEM gene concurrently. ConclusionsThe producing rate of ESBL is increasing year after year and the SHV type of ESBL is the dominant one.Strains with more than one type of ESBL gene are increasing.The antibiotic resistance rates to cefotaxime, ceftriaxone and ceftazidime are statistically different between strains with same ESBL genotype.

Objective Try to know the prevalence rate of ESBL-s produced by Eseherichia coil in our hospital from 2003 to 2007.Methods Antibiotic susceptibility were determined by K-B disc diffusion.Double-disk synergy tests performed on Mueller-Hinton agar plates was used for ESBL confirmation.Results There was 23.8% of our isolates can produce ESBLs in 2003,25.4% in 2004,31.3% in 2005,36.6% in 2006 and 44.9% in 2007,respectively.The situation of antibiotic resistance is more severe.Conclusion The antibiotic resistance should be well surveyed and the ESBLs must be routinely assayed.

To study the expression of some protooncogenes in burn wounded skin tissue. Methods: The protooncogene expression was analysed by mRNA dot blot hybridization,autoradiography and densitermeter. Results: Thermal injury induced C-myc, C-myb, C-jun and C-sis mRNA expression. How-ever, those four protooncogenes showed different expression models. Expression of C-myc and C-jun in-creased at d 1, and peaked 1 and 3 d postburn, respectively. Expression of C-myb and C-sis increased 3and 5 d, and peaked 10 d after thermal injury. Conclusion: Thermal injury can induce some protooncogeneexpression which sh0wed temporal order and well controlled manifestation. Those results suggest thatthose four protooncogenes are involved with the repair process as a regulator.

Objective To investigate the variation and correlation between tumor necrosis factor-?(TNF-?)and transforming growth factor-?1(TGF-?1)in children with Henoch-Schonlein purpura nephritis(HSPN)in plasma and explore their effects on kidney lesion in children with Henoch-Schonlein purpura(HSP).Methods Plasma TNF-? and TGF-?1 were determined with enzyme-linked immunosorbent assay(ELISA)in 30 cases with HSP,38 cases with HSPN and 30 normal controls,urinary protein excretion with urinary analyze method in these children.Renal biopsies were performed and renal biopsy specimens were observed by light,immunofluorescence and electron microscopy in 32 out of 38 cases with HSPN.The SPSS 11.0 software was used to analyze the data.Results 1.Comparing with normal controls,the plasma level of TNF-? and TGF-?1 in children with HSP increased with significant difference in statistics(Pa

Objective To investigate the effect of insulin on D_5 dopamine receptor expression and function in renal proximal tubule (RPT).Methods Immortalized RPT cells and D_5 receptor transfected HEK293 (HEK-D_5) cells were used in the study to investigate the effect of insulin on D_5 receptor expression and function,and those effects were compared in RPT cells from Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR). The function of D_5 receptor was determined by measurement of the Na~+-K~+-ATPase activity in HEK-D_5 cells. Results Insulin increased D_5 receptor protein expression in a concentration and time-dependent manner in WKY RPT cells,but not in SHR.The basal level of D_5 receptor expression was higher in WKY cells than that in SHR cells. Stimulation with fenoldopam(D_1-like dopamine receptor agonist) inhibited the Na~+-K~+-ATPase activity;pretreat- ment with insulin increased the inhibitory effect of fenoldopam on Na~+-K~+-ATPase activity in HEK-D_5 cells. Conclusion The abnormal regulation of insulin on D_5 receptor expression and function might be involved in the path- ogenesis of essential hypertension.

Objective To examine the expression and analyze the significance of autophagy-related gene microtubule-associated protein 1 light chain 3 (MAP1-LC3,LC3),p62 and lysosorne-associated membrane protein 2 (LAMP-2) in pancreatic tissues of mice with acute pancreatitis (AP).Methods Twenty mice were randomized into AP group and control group,and the number of mice was equal between two groups.AP group was intra-peritoneally injected by 20％ L-arginine solution (two injections of 4 g/kg body weight,every 1 h) in the dosage of 4 g/l kg twice every 1 hour to establish AP model,while control group was administered with equal volume of normal saline by intra-peritoneal injection.All the mice were euthanized at 24 hour after the last injection.Pancreatic histopathological changes were measured.In addition,the protein expressions of LC3,p62 and LAMP-2 were detected by Western blot.Results No obvious pathological changes were observed in control group.Pancreatic acinar edema,structure destruction,missing,the obvious widening of interlobular septum,small interlobular septum and acinar septum,and the necrosis of acinar cells at different degrees were observed in AP group.The pathological score for tissue edema,hemorrhage,necrosis and inflammation in AP group was 3.13 ± 0.50,2.83 ± 0.32,3.25 ± 0.46 and 3.16 ± 0.47,respectively,which was all 0 in control group.The differences were statistically significant between AP group and control group (P ＜ 0.01).In AP group,the ratio of LC3-Ⅱ/LC3-Ⅰ,p62 and LAMP-2 protein in pancreatic tissue were 1.16 ± 0.08,0.94 ± 0.04 and 0.35 ± 0.04,respectively,which were 0.24 ± 0.02,0.34 ± 0.03 and 0.95 ± 0.03 in control group.The ratio of LC3-Ⅱ/LC3-Ⅰ and p62 protein in pancreatic tissue in AP group were much higher than those in control group,while LAMP-2 in AP group was lower than that in control group,and there was statistically significant difference between two groups (all P ＜0.01).Conclusions Intraperitoneal injection of L-arginine could induce acute pancreatitis,and autophagy is impaired,which was associated with decreased LAMP-2 protein expression.

ObjectiveTo study the effect and mechanism of NGF gene modified SCs on DRG (dorsal root ganglion) neurons repair after compressed injury.MethodsSCs were obtained by one enzyme digestion method.SCs were transfected with NGF gene by adenovirus.Thirty-two female SD rats with compression injury of dorsal root ganglia on right lumbar nerve roots.were divided randomly into following groups:Normal saline(NS) group,Pure SCs group,Ad-NGF group,and SCs+NGF group.Nerve root tissues were harvested 2 weeks after treatment.Western blot were used to detect the proNGF volume in nerve root tissue lysis; Double-labeling fluorescent Immunohistochemistry(IHC) was used to count the number of β-Tubulin Ⅲ positive cells and activating transcription factor 3 positive cells.The ratio of injured neurons to survived neurons was calculated.ResultsWestern bolt showed the proNGF volume in nerve root tissue lysis of SCs+NGF group increased dramatically.Double-labeling fluorescent IHC showed SCs+NGF group vs any group,the density of survived DRG neurons(β-Tubulin Ⅲ positive cells) increased significantly,meanwhile the percentage of injured neurons (ATF3 positive cells) in survived neurons decreased dramatically.Conclusion NGF gene Modified SCs could promote the survival of DRG neurons after compression injury and decrease the ratio of injured neurons.We conclude that this study provides a new treatment strategy for the patients who suffer from chronic compression injury on nerve roots and DRG neurons.
