Objective To investigate the clinical characteristics of septicemia in type 2 diabetes mellitus,to enhance prevention level and decrease death rate.Methods A retrospective study was carried out,the data were collected from 58 cases of type 2 diabetes mellitus complicated by septicemia in our hospital in the past 13 years.Results The pathogenic invasive pathways included:19 cases of urinary tract,17 cases of respiratory tract,7 cases of intravenous catheter detain,7 cases of biliary tract,1 case of skin breakage,and 7 cases of unclear origin.Twenty-three of 58 cases were from nosoeomial infection (39.7%),among which 10 cases of urethral detain,7 cases of intravenous catheter detain,and 6 cases of respiratory tract infection.Pathogenic distribution was as following:24 cases of klehsiella pneumoniae,16 cases of escherichia coli,10 cases of staph aureus,2 cases of staphylococcus cohnii cohnii,2 cases of staphylococcus epidermidis,2 cases of pseudomonas putida,2 cases of candida glabrata.Among the 24 cases of llehsiella pneumoniae,12 cases showed migrating hepatapostema (50.0%),and 15 showed pneumatosis phenomenon in the intrahepatie bile (62.5%).Two cases originated from fungal septicemia.Among 56 cases under antibacterial therapy 15 cases developed fungal septicemia (26.8%).Fifty-eight cases were treated with insulin for forcing down serum glucose,56 cases of bacterial septicemia were treated with the third generation cephalosporins and fluoroquinolones.Two cases of pseudomonas putida septicemia were treated with intravenous injection of fluconazole.Seven cases died (12.1%).Conclusions Gram-negative bacilli were the major pathogens of septicemia in type 2 diabetes mellitus.Migrating hepatapostema and pneumatosis phenomenon in the intrahepatic bile often showed klebsiella pneumoniae septicemia.The important risk factors for septicemia were intravenous catheter detain and urethral detain.Therefore,strictly aseptic operation and removing vessel detain in time is very important.It is key points to make an early diagnosis,have a strong antibiosis therapy and treat the migrating pathogenic focus.And it is important to intensify serum glucose monitoring and strengthen supportive treatment.

Objective To investigate the resistant mechanism of imipenem-resistant K. pneumoniae.Methods The minimal inhibitive concentrations (MICs) of the antimicrobial agents were determined by Etest.Isoelectric focusing electrophoresis (IEF),plasmid extraction,conjugation, transformation,PCR amplification,cloning and sequencing were carried out for analyzing the encoding gene of ?-1actamases.Results Three kinds of ?-1actamases were detected with pIs of 7.2,6.7,and 5.4.in a clinical strain of K.pneumoniae.These ?-1actamases were TEM-I (pI,5.4),SHV-12 (pI,8.2) and KPC-2 ( pI,6.7 ) confirmed by sequencing of the PCR products.Only one band of ?-1actamase with pI 6.7 was displayed in the transformant.A 1500 bp segment,which contained the KPC-2 gene confirmed by nucleotide sequence analysis,was cloned from a 60 000 bp plasmid of the transformant.Conclusion The strain of K.pneumoniae resistant to imipenem produces a plasmid-mediated carbapenemase KPC-2 which belongs to Bush group 2f,class A ?-1actamase.

Objective To evaluate the applied value of multislice CT (MSCT) in the selection of living donor kidneys and excision methods.Methods Ninety living renal donors underwent MSCT assessment.The nonenhanced,arterial,venous and excretory phase examinations were performed.Using maximum intensity projection and volume rendering techniques for vascular imaging,two blinded radiologists independently analyzed and evaluated all MSCT images.According to the CT reconstructive images,radiologists and physicians selected the left renal or the right renal donors,and chose laparoscopic or open live donor nephrectomy.Results On the 90 cases of donors,78 donors underwent nephrectomy in the left kidney.Seventy-one left kidney donors having no significant variation received the routine laparoscopic live donor nephrectomy.Seven left kidney donors on both sides had relatively obvious anatomical variations such as accessory renal artery,multi-branch renal vein and renal vein in the back of the abdominal aorta,and they were subjected to the left kidney open donor nephre.ctomy.Other 12 donors having significant variation in the left kidney were given nephrectomy in the right kidney,and all of them received hand-assisted laparoscopic live donor nephrectomy.All intraoperative records of urine collection system and renal vascular anatomy were consistent with the preoperative evaluation of MSCT,and the accuracy was 100 %.Two imaging experts in the evaluation of renal artery,renal vein and urine collection system showed good consistency.Nephrectomy was successfully performed on 90 cases of donors,and.postoperative recipients had no renal vein thrombosis and other vascular complications.Conclusion MSCT can provide accurate and valuable information for the selection of living donor kidneys and excision methods as a “one-stop” technique for the preoperative evaluation of living renal donors.

Genomic DNA was extracted from the blood samples of 3 patients from 1 pedigree with congenital nephrogenie diabetes insipidus (NDI) and their 12 family members.The whole coding region of the arginine vasopressin receptor 2 (AVPR2) gene was amplified by PCR and then directly sequenced,A mutation of AVPR2 gene [g1236T→C (L292P)]was found in 3 patients.The patients' mothers were found to have both mutant and normal alleles.

Backgroud and Objective Proline-rich tyrosine kinase2(Pyk2) is a Ca~(2+) sensitive,non-receptor tyrosine protein kinase.Previous reports showed Pyk2 involved in development of left ventrieular hypertrophy. The present paper aimed to study the effects of valsartan on ventricular hypertrophy and its effect on the expression of Pyk2 in myocardium in renovascular hypertensive rats(RHR).Methods Two-kidney and one-clip(2K1C) renal hypertensive model was established in Sprague-Dawley rats by chronic partial occlusion of left renal artery,and ran- domized to receive valsartan (30 mg/kg?d) or without treatment for 4 or 8 weeks.Left ventricular mass to body mass ratio was measured.Pyk2 protein expression and phosphorylation was detected by Western blotting.Results Blood pressure,left ventricular mass to body mass ratio,Pyk2 activity in myocardium of RHR were increased gradu- ally.Valsartan reduced BP and prevent myocardial hypertrophy(P

Objective:To investigate the prognosis of cT3 and the subgroups of low rectal cancer patients who underwent neoadju-vant chemoradiotherapy (CRT) and evaluate whether all patients with cT3 low rectal cancer should undergo CRT. Methods:A total of 223 patients with cT3 low rectal cancer treated in the Department of Colorectal Surgery of Fujian Medical University Union Hospital from January 2008 to December 2012 were divided into neoadjuvant chemoradiotherapy group (CRT group) (115 cases) and no neoad-juvant chemoradiotherapy group (nCRT group) (108 cases) according to whether the patients underwent CRT. Afterward, the patients were retrospectively divided into three subgroups (mrT3a, mrT3b, and mrT3c) according to the proposed criteria of the Radiologic Soci-ety of North America (RSNA) by measuring the depth of mesorectal invasion (DMI) (DMI<5, DMI=5-10, and DMI>10 mm). The prog-noses of the two groups and their subgroups were compared. Results:The CRT and nCRT groups revealed no significant differences in the 3-year disease-free survival rate and the local recurrence rate for all the mrT3 patients (78.2%vs. 71.9%, P=0.608;4.4%vs. 8.5%, P=0.120) and mrT3a patients (82.4%vs. 81.8%, P=0.837;5.8%vs. 5.9%, P=0.658). On the contrary, for the mrT3b patients, the CRT and nCRT groups revealed significant differences in the 3-year disease-free survival rate (84.4%vs. 42.4%, P=0.032) and local recurrence rate (0.0%vs. 18.2%, P=0.014). For the mrT3b,c patients, the CRT and nCRT groups revealed no significant difference in the 3-year dis-ease-free survival rate (72.8%vs. 42.4%, P=0.060) but revealed a significant difference in the local recurrence rate (2.4%vs. 18.2%, P=0.021). COX regression analysis was utilized for 3-year disease-free survival, DMI and circumferential resection margin (CRM) were significant in the univariate analysis. Additionally, the multivariate analysis indicated that CRM is an independent impact factor (OR=2.249, CI 1.067-4.742, P=0.033). Conclusion:CRT can improve the prognosis of patients with mrT3b,c low rectal cancer but may not significantly influence the prognosis of patients with mrT3a and CRM-negative low rectal cancer;surgical treatment can be performed in these patients without CRT.
