For the patients with elevated lactic acid level,peak lactic acid level,12h lactic clearance were good indicators to evaluate patients' prognosis.

Objective To evaluate the clinical and biochemical characteristics of type 2 diabetics with hyperuricemia and to investi-gate the association between serum uric acid and the number of metabolic syndrome components. Method In the cross-sectional study of 547 type 2 diabetics, we recorded body mass index (BMI), systolic blood pressure(SBP), diastolic blood pressure (DBP), and collected blood samples to measure serum uric acid (UA), fasting plasma glucose (FPG), glycosylated hemoglobin (HbAlc), creatinine (Cr) and blood lipid profile, including tfiglyceride (TG), total cholesterol (TC), low-density cholesterol LDL-C) and high-density cholesterol (HDL-C). Results Compared with the normal UA group, the diabetic patients in the high UA group had significantly increased levels of BMI, SBP, DBP, FPG, Cr, TG, TC and HbA1c (P <0.05, P <0.01, P <0.05, P <0.01, P <0.01), and decreased level of HDL-C(P < 0.05). There was no significant difference in the level of LDL-C between the two groups (P > 0.05). According to their possession of 1, 2, 3 or 4 components of metabolic syndrome, 547 cases were divided into four groups (MSI, MS2,MS3 and MS4). There were significant difference in the levels of UA, BMI, SBP, DBP, Cr, TG, TC, LDL-C and HDL-C among MSI, MS2, MS3 and MS4 (All P < 0.05). Multiple regression analysis showed that UA concentration was positively correlated with sex, TG and Cr (Beta:0. 088,0. 350, 0. 124; P < 0.05, P <0.01, P <0.01) and negatively correlated with HDL-C and HbA1 c(Beta: -0.107, -0.124 ; P <0.01, P <0.01). The con-centration of UA was strongly correlated with serum TG. Conclusions Serum UA level in type 2 diabetics was significantly elevated as the number of metabolic components increased. Abnormal TG had great influence on serum UA. Hyperuricemia was considered to be a dangerous factor of the metabolic syndrome.

Objective To investigate the expression of visfatin mRNA in abdominal omental adipose tissue and its relationship with blood lipid in type 2 diabetes mellitus.Methods 161 type 2 diabetic patients were divided into two groups according to triglyceride ( TG ),high triglyceride group ( TG ≥ 1.7mmol/L) and normal triglyceride group(TG ＜ 1.7 mmol/L).The expression of visfatin mRNA in abdominal omental adipose tissue was measured with Northern Blot.Visfatin plasma concentration,fasting plasma glucose (FPG),blood lipid profiles and other biochemical indicators were also measured.Results Comparing with normal triglyceride group,the diabetic patients in high triglyceride group had significantly increased levels of visfatin plasma concentration [ ( 129.07 ± 21.35)ng/mL vs ( 101.65 ± 15.23 ) ng/mL,t =2.295,P ＜0.05]and mRNA expression in omental adipose tissue( P ＜0.05).Visfatin plasma concentration was positively correlated with TG( β =0.592,P ＜0.05 ) and FPG( β =0.763,P ＜0.01 ).Visfatin mRNA expression in omental adipose tissue had no correlation with FPG,TG and other biochemical indicators.Conclusions The plasma visfatin level in T2DM patients may be associated with triglyceride metabolism.

Objective To explore the efficacy and postoperative survival times of stereotactic radiosurgery by X-knife in the treatment of brain metastatic tumors.Methods Between March 1996 and March 2008,520 patients with brain metastatic tumors were treated in our hospital by stereotactic radiosurgery using X-knife.Among the cases,336 had single metastatic lesions,and 184 presented with multifocal tumors(2 lesions in 51 patients,3-5 lesions in 63,and 6-10 lesions in 70).The tumors sized 5 to 35 mm in diameter with a mean of 16.4 mm.Stereotactic radiosurgery was carried out in the cases with a mean central dose of 22 Gy(20 to 25 Gy),and mean marginal dose of 12 Gy(10 to 14 Gy).Over 80% of the lesions were encircled with the dosage.Results The 520 patients were followed up for 8 to 36 months(mean,20 months).CT and MRI performed in the 6th months postoperation showed complete response in 218 patients(41.9%),partial response in 182(35.0%),no response in 78(15.0%),and progressed disease in 42(8.1%).The overall control rate of the tumors were 91.9%(478/520).In this series,the 6-months survival rate was 85.0%(442/520),12-month survival rate was 68.1%(354/520),and the 1-year and 3-year survival rates were 40% and 5.5% respectively.The medium survival time was 12.6 months.Conclusions Stereotactic radiosurgery is an effective method for brain metastatic tumors.It can improve the life quality and survival time of the patients.

OBJECTIVE To investigate the antimicrobial resistances of Gram-negative bacilli isolated from patients with lower respiratory infection in intensive care unit(ICU),so as to provide reasonable selections for antibiotic in clinical treatment.METHODS The phlegm specimens from ICU inpatients with lower respiratory tract infection were collected from 2004 to 2007,and drug sensitivity test was performed according to NCCLS standards.RESULTS Gram-negative bacilli were accounted for 75.2% of total strains.The most predominant pathogens were Pseudomonas aeruginosa(42.7%),Acinetobacter baumannii(16.3%),Sternotrophomonas maltophilia(10.4%),Escherichia coli(10.0%),and Klebsiella pneumoniae(6.7%).The prevalence of ESBLs in E.coli and K.pneumoniae increased from 54.5% and 37.5 % in 2004 to 65.6 % and 52.7% in 2007.ESBLs non-producing strains showed lower resistance rates to the aminoglycosides,quinolones and the third and fourth generation cephalosporin than those of ESBLs producing strains.Nonfermentative Gram-negative bacilli were very highly resistant to most antimicrobial agents.CONCLUSIONS The drug resistance rates of Gram-negative bacilli of lower respiratory tract are serious.It is important to investigate the antimicrobial resistances of pathogenic bacteria and rationally use of antibiotics.

Objective To investigate the changes in molecule levels of Ras-ERK signal pathway of K562 cells treated with simvastatin in vitro,and to illustrate that simvastatin inducing the changes in molecule levels of Ras- ERK signal pathway is involved in regulation of proliferation and apoptosis of K562 cells. Methods K562 cells,the chronic myelocytic leukemia(CML) cell lines,were cultured and treated with simvastatin in vitro and proliferation activity of K562 cells was detected by MTT. The changes of apoptosis rate and cell cycle of K562 cells were measured by flow cytometry(FCM). The molecular changes of Ras-ERK signal pathway were analyzed by RT- PCR in transcriptional level. Results The proliferation of K562 cells was inhibited by simvastatin,and G_0-G_1 arrested in K562 cells and significant apoptosis rate was observed with FCM. Most molecules of Ras- ERK signal pathway expressed differentially at transctiptional level. Conclusion Simvastatin probablely inhibit proliferation and induces apoptosis of K562 cells,depending on Ras-ERK signal pathway which is involved in cell proliferation and apoptosis.

Objective To explore the effect of swimming and caressing on neonatal jaundice and weight.Methods Two hundred and forty newborns were divided equally into control and observation group with random digits table.The former received care with caressing and the latter with swimming and caressing.The two groups were compared in terms of weights and jaundice indices at birth and 7d after birth.Results Seven days after birth,the jaundice index in the observation group were lower than that of the control group and the weights of the observation group were larger(P<0.05).Conclusion Swimming and caressing are helpful for the development of neonates by C-sect and the reduction of jaundice duration.

Objective To investigate the effect of rosiglitazone on the epithelial-mesenchymal transition process of renal tubular epithelial cell induced by transforming growth factor-β(TGF-β). Methods The human renal tubular epithelial cell line HK-2 was cultured in vitro and treated with TGF-β at the presence or absence of rosiglitazone, and the morphological changes of HK-2 cells were observed. Then PPARγ,SMAD family number 2/ 3,E-cadherin and Vimentin were detected by western blot, and the mRNA expression of PPARγ, E-cadherin, Vimentin, zinc finger transcription factor Snail and Slug were measured by realtime quantitative PCR. Finally,dual luciferase reporter assay was performed to detect the effect of TGF-β and rosiglitazone on the tran-scription activity of E-cadherin promoter. Results TGF-β could induce the EMT process of HK-2, including morphological changes such as longer pseudopod and broader cell space. TGF-β also activated the SMAD2/ 3 signaling pathway, with expression changes of E-cadherin and Vimentin. Rosiglitazone reversed the morphological changes of HK-2 cells induced by TGF-β, with shor-ter pseudopod and narrower cell space. Rosiglitazone also inhibited the mRNA and protein expressions of Vimentin, and restored the mRNA and protein expression of E-cadherin by up-regulating PPARγ. The activity of E-cadherin promoter was enhanced under the treatment of rosiglitazone. Conclusion Rosiglitazone can antagonize the EMT process of renal tubular epithelial cell induced by TGF-β, through the activation of PPARγ and stimulating transcription and protein expression of E-cadherin.
