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 study the correlation between blood lactic acid level and PCIS scroing system.To study the relationship between dynamic lactic acid monitoring indexes and prognosis of critical patients.Methods Differences of mortality,incidence of MODS and shock,PCIS score between two groups were compared.The patients were divided into 3 groups by PCIS score to compare pathogenetic conditions prognosis, then to study the were divided into death group and survival group by the hospital prognosis. Differences of their lactic indexes and other clinical indicators which reflected organ/system status were compared, prognostic-significant lactic indexes were selected by mu fti-variable logistic analysis. Results Patients with elevated lactic acid level had more incidence of shock and MODS, higher PCIS scores and higher mortality, the differences had statistical significance compared with the normal lactic acid group. There were significant linear correlation between ICU lactic acid level, peak lactic acid level and PCIS scores respectively. For the patients with elevated lactic acid level, peak lactic acid level, 12h lactic clearance had significant correlation with prognosis. Conclusion PCIS scoring system had a significant linear correlation with lactic acid level. For the patients with elevated lactic acid level,peak lactic acid level,12h lactic clearance were good indicators to evaluate patients' prognosis.

Objective To investigate the effect of the dihydroartemisinin (DHA) on the human low-differentiated lung adenocarcinoma cell line A549 and to explore its mechanism. Methods The A549 cells at logarithmic growth phase were divided into control group and DHA group. The cells in the control group were incubated with conventional reagent, and the cells in DHA group were incubated with 500 nmol/L of DHA. After incubation for 72 hours, methyl thiazolyl tetrazolium (MTT) assay was used to examine the proliferation of A549 cells in the two groups. Gene expression of p85, Akt, Bax and Bcl-2 was detected by real-time fluorescence quantitative polymerase chain reaction (PCR) . The protein expression of p85, Akt, p-p85, p-Akt, Bax and Bcl-2 was detected by Western blotting method. The activity of Caspase3 was measured by Caspase3 colorimetric assay kit. Results Compared with the control group, the proliferation rate of A549 cells in DHA group was significantly decreased ( P<0.01) . The RT-PCR results showed that the mRNA expression levels of p85 and AKT had no obvious difference between the two groups, but the mRNA expressien level of Bax was increased ( P<0.001), and the mRNA expressien level of Bcl-2 was decreased ( P<0.05) . The Western blotting results showed that there was no significant changes of p85 and Akt proteins between the two groups (P>0.05), but p-p85, p-Akt and Bcl-2 protein expression levels were significantly decreased ( P<0.01) , and Bax protein expression was increased ( P<0.01). Moreover, the activity of Caspase3 was also enhanced ( P<0.001). Conclusion DHA can reduce the proliferation of A549 cells and increase the apoptosis of A549 cells, and its mechanism probably has relationship with the inhibition of PI3K/Akt signaling pathway.

[Summary] Radical prostatectomy, external beam radiation and active surveillance are the main treatments for localized prostate cancer. However, many patients are difficult to accept the psychological burden of active surveillance and the distress caused by potential side effects of radical therapy, including incontinence and erectile dysfunction, which make them limited. With the development of minimally invasive techniques, such as brachytherapy, cryoablation, high-intensity focused ultrasound, photodynamic therapy, and irreversible electroporation, novel procedures are playing an increasingly important role in the treatment of localized prostate cancer with their effective, minimally invasive, and safe advantages. This article mainly reviewed the above several minimally invasive treatment methods.

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.

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.
