Objective To study the Genotype of local clinical isolates of Enterobacteriaceae producing extended spectrum ? lactamases. Methods K B test, conjugative transfer test, plasmid profile analysis, PCR, PCR RFLP, and DNA sequencing were used to detect the phenotype and genotype of 33 isolates of Enterobacteriaceae producing ESBLs. Results Eighty five percent of 33 isolates was resistant to cefotaxime which was obviously higher than that to ceftazidime. blaCTX M ESBLs was detected in 28 isolates by PCR, blaTEM DNA in 24 isolates, and blaSHV DNA in 9 isolates. Mutation of E104K was only identified in one TEM ? lactamase produced by EC98A7 by PCR RFLP. No substitution of G238S occurred in 9 SHV ? lactamases. DNA sequencing and DNA alignment showed the blaCTX M DNA fragments from 4 clinical isolates of EC98A7,EB56,CFR78 and, KP9941 belonged to CTX M type 1, with highest identity to blaCTX M 3 or blaCTX M 12 respectively. Conclusions CTX M ESBLs is carried in 85% isolates of Enterobacteriaceae producing ESBLs in this city. Most of the isolates carry 2 or more ? lactamases. E. coli EC98A7 produces two ESBLs, a TEM ESBL and a CTX M ESBL.

Objectives To study the effects of effective constituent of Cortex Moutan-Paeonol and Paeoniflorin on myocardial ischemia and myocardial infarction in experimental canines.Methods The coronary artery ligation was employed to establish the model of canines with acute myocardial ischemia and myocardial infarction.The extent of myocardial ischemia was detected by epicardial-electrocardiogram and the extent of infarction was determined by N-BT staining method.Results The adminstration of Paeonol and Paeoniflorin reduced the myocardial ischemia level(P

Metabolic syndrome was once regarded as deadly quartet.This is make up by diseases of various metabolism.The incidence is increased with age.This review is to introduce recent advances in the epidemic,major risk factors,clinical symptoms and diagnosis.Early health education,diet therapy,exercises and drugs can prevent or delay the occurrence and progress of metabolic syndrome.

Hypertrophic cardiomyopathy is one of the most common inherited cardiovascular diseases and characterized by ventricular hypertrophy and myofibrillar disarrays. HCM affects patients of all ages, but is frequently diagnosed in patients over age 50. The pathology, genetics, diagnosis and treatment of HCM are reviewed.

Objective To explore the effect of endoscopic sinus surgery on inverted papilloma of nasal cavity and paranasal sinuses in 30 cases.Methods 30 patients with inverted papilloma of nasal cavity and paranasal sinuses were operated on by endoscopic sinus surgery.Results During a follow-up of 2～3 years,only four cases recurred, Conclusion Endoscopic sinus surgery had advantsges of clear field and little injury,and therefore it was effective for inverted papilloma of nasal cavity and paranasal sinuses.

Skillful in the treatment of gouty arthritis (GA) by integrated therapies of Chinese and Western medicine,chief physician Zhang Tang-fa proposes to ‘deal with the exterior with the needles,and attack the interior with the drugs,by integrated application of acupuncture and herbal medicine',in combination with comprehensive intervention of dietetic therapy and health education.In the treatment of GA,he adopts the syndrome differentiation based upon the pathogenic factors,in combination of syndrome differentiation based upon the six meridians,to reinforce and benefit the spleen and kidney,clear away heat and remove dampness as the therapeutic principle.By acupuncture mainly at the acupoints of the Spleen and Liver Meridians,he also proposes to select the acupoints by the theory of Na Zi Fa (earthly branch method) of Zi Wu Liu Zhu (midnight-noon ebb-flow),and to puncture the surrounding area of the involved joints shallowly by multiple needles as the major needling method,simultaneously with the reinforcing and reducing manipulations based upon the respiration.In the treatment,acupuncture and acupoint-injection are often used.In diet,low purine diet is often suggested.In health education,the patients are often instructed to understand the disease correctly,eliminate fears and cooperate with doctor's treatment positively.

Objective To investigate the effects of MG132 on diabetic nephropathy (DN) rats induced with streptozocin. Methods Seventy-two male SD rats were randomly divided into three groups: normal control group (NC, n=24), DN group (n=24) and DN treated with MG132 group (DN+MG132, n=24). At the end of 4, 8 and 12 weeks, 24 hour urinary protein excretion rate (UPER) was detected. Morphology of kidney was examined by special staining of periodic acid-schiff (PAS). Renal 26S proteasome activity was determined by quantifying the hydrolysis of S-LLVY-AMC in a fluorescence reader. Urinary malondialdehyde (MDA) level and renal SOD and GSH-PX activity were detected by commercial kits. Renal SOD, GSH-PX and p47phox mRNA expressions were determined by real-time fluorescence PCR. Renal p47phox protein expression wasdetermined by Western blotting. Results Compared with NC group, the DN group showed a significant increased of UPER at week 4, 8, 12 (all P<0.05), of mesangium proliferation and mesangial matrix expansion at week 12. In DN+MG132 group, UPER was significantly decreased compared with DN group at the end of 4, 8 and 12 weeks (P<0.05, respectively), and the glomeruler pathological alteration induced by diabetes was attenuated. Increased renal 26S proteasome activity in DN rats was significantly inhibited after MC132 administration (P<0.05). Moreover, renal p47phox mRNA expression in DN group was 155%, 149% and 120% more than those in NC group at 3 time points (all P<0.05), and so was the renal p47phox protein expression, 139%, 152% and 186% more (all P<0.05). Urinary MDA levels in DN group were 1.95-, 2.04-and 2.62-folds more than those in NC group (all P<0.05). In addition, compared with NC group at 3 time points, in DN group, renal SOD activity was decreased by 23.09%, 33.59% and 53.31% (all P<0.05); renal GSH-PX activity was decreased by 28.57%, 33.06% and 48.76% (all P< 0.05); renal SOD mRNA was decreased by 38.09%, 61.44% and 76.53% (all P<0.05); renal GSH-PX mRNA group was decreased by 29.16%, 37.26% and 62.40% (all P<0.05). Compared with DN group, renal p47phox mRNA and protein expression, and urinary MDA levels were significantly lower in DN+MG132 group (all P<0.05); renal SOD and GSH-PX activity as well as mRNA expression were significantly increased in DN+MG132 group (all P<0.05). Conclusions MG132 treatment can provide renoprotection for DN rats effectively maybe through enhancing renal anti-oxidative ability.
