Objective To investigate the possible mechanism that hepatocyte growth factor (HGF) inhibits renal tubular epithelial-mesenchymal transition (EMT),and to determine whether Smurf2 expression induced by TGF-β1 can be reversed by HGF in normal rat kidney epithelial cells (NRK-52E).Methods Using rat NRK-52E cell line as an in vitro system,NRK-52E cells were incubated with 5 μg/L TGF-β1 for 0-24 h.Part of cells were pretreated with 20 μg/L HGF for 30 min or not,then incubated with or without 5 μg/L TGF-β1 for 1 h or 48 h.The other cells were transfected with pFlag-Smurf2 or Smurf2 siRNA for 24 h,then treated with or without 20 μg/L HGF for 24 h.The expressions of Smurf2,SnoN,E-cadherin,alpha-smooth muscle actin (α-SMA) and fibronectin (FN) were detected by Western blotting and indirect immunofluorescence staining assays.Results Compared to normal control,TGF-β1 could rapidly induce Smurf2 protein expression in a short time (P＜0.01).Meanwhile,the expressions of FN and α-SMA were significantly induced,and the expression of E-cadherin was reduced in NRK-52E cells by TGF-β1.In contrast,in the NRK-52E cells pretreated with HGF,HGF could obviously inhibit Smurf2 expression induced by TGF-β1,and reversed the down-regulation of SnoN (P＜0.01) and E-cadherin (P＜0.05),the up-regulation of α-SMA (P＜0.01) and FN (P＜0.01) induced by TGF-β1.Moreover,overexpression of Smurf2 in NRK-52E cells could partly inhibit the up-regulation of SnoN protein by HGF,while down-regulation of Smurf2 could up-regulate the expression of SnoN induced by HGF.Conclusions HGF can abolish EMT induced by TGF-β1 in renal tubular epithelial cells through down-regulating Smurf2 expression and suppressing ubiquitin-proteasome dependent degradation of SnoN.

Objective To discuss The Clinical Significance of Eosinophil (EOS) in urosepsis. Methods A total of 99 patients of urosepsis in Department of Urology,Guangdong Provincial TCM Hospital from Mar. 2013 to Jul. 2016 were selected as research objects by retrospective analysis. The patients were classified into groupEOS= 0 andgroup EOS > 0,group PCT(procalcitonin)≥ 2 ng/mL andgroup PCT < 2 ng/mL,the differences of PCT concentration and percentage of EOS in two groups were analyzed comparatively. 99 patients of urosepsiswere also compared the difference of the percentage of EOS with another group including 100 patients of urinary tract infection (UTI) without Sepsis. Results The percentage of EOS was significantly decreased in 86.9%(86/99)of patients of urosepsis. The paired student t test show the percentage of EOS in two days after treatment,four days after treatment, before hospital discharge were higher than that before the treatment, the difference wassignificant (P < 0.05). The Independent-Sample Test show that the PCTconcentration in EOS = 0 group were higher than EOS > 0 group,the percentage of EOS in PCT≥2 ng/mL groupwere lower than PCT<2 ng/mL group,difference were significant(P<0.05). And The Independent-Sample Testalso showed that the percentage of EOS of the Urosepsis group was definitely lower than the UTI group without Sepsis. Difference was statistically significant. Concusions The percentage of EOS could be applied to assess the severity of urosepsis, monitor the disease progression and evaluate the infection control. The cost was lower than PCT in therapeuticprocess ofurosepsis.

Objective To investigate the feasibility and safety of portal 125I seed stent implantation combined with doxorubicin-eluting beads transcatheter arterial chemoembolization (DEB-TACE) for the treatment of hepatocellular carcinoma (HCC) associated with main portal vein tumor thrombus (MPVTF).Methods Prospective single-arm study was designed.Seven HCC patients with MPVTT were sequentially enrolled in this study to receive treatment.Portal pressure before and after portal vein stent implantation were determined,the liver function were tested before and 1-3 days,4 days,5-7 days after portal vein stent implantation,the results and the postoperative complications were analyzed.Results All 7 patients were in BCLC-C stage,with Child-Pugh classification being A-B level.All patients were diagnosed as massive type HCC complicated by portal vein tumor thrombus.The lesions were located in hepatic left lobe (n=l) and hepatic right lobe (n=6),tumor thrombus in left branch of portal vein was seen in one patient and tumor thrombus in right branch of portal vein was found in 6 patients,MPVTT was observed in all 7 patients.Portal 125I seed stent implantation plus DEB-TACE was successfully accomplished in all 7 patients.The portal pressure before and after stent implantation was 15.3 cmH2O and 10.2 cmH2O respectively,the postoperative pressure showed an obvious reduction.After stent implantation,a transient elevation of the serum total bilirubin (TB),alanine aminotransferase (ALT) and aspartate aminotransferase (AST) could be observed,which gradually decreased in 3-4 days;the recovery of TB level was slower than that of ALT and AST levels.Two patients had concomitant myocardial damage,which was gradually recovered in 2-3 days.Conclusion For the treatment of HCC associated with MPVTT,portal 125I seed stent implantation plus DEB-TACE is safe and feasible,although its long-term curative effect needs to be further clarified.

Objective To further intensify the reform of public hospitals,promote talents team building and scientific research management innovation,enhancing the overall capacity of care delivery,as well as the development of science and technology in grass-roots hospitals.Methods A series of measures were adopted to arouse the enthusiasm of personnel to conduct research and finally increase the research outcomes.Concrete measures include talent training program and scientific research man-agement innovation,construction funding assurance,whole-process dynamic management,clarification of the quantitative evaluation index,research rewards,research funding management,as well as performance management.Results After implementation of such measures,the academic atmosphere changed a lot,medical technology improved,the quality of scientific research,project application and research outcomes increased dramatically which has statistical significance compare to previous situations.Conclusions The establishment of the incentive system plays a significant role.It helps in talent agglomeration during a relatively short period of time,exploring the potential capabilities of scientific research,enhancing the core competitiveness of hospital scientific research,which provide strong intellectual support and talent guarantee for hospitals development.

OBJECTIVETo observe the intervention effects of acupuncture combined with standardized treatment of western medicine on blood-stasis syndrome in unstable angina (UA) patients with different thrombolysis in myo-cardial infarction (TIMI) risk stratification.

METHODSAccording to TIMI risk score, a total of 72 UA patients were included, 24 cases in low-risk (0 to 2 points) group, 24 cases in moderate-risk (3 to 4 points) group and 24 cases in high-risk (5 to 7 points) group. Based on routine standardized treatment of western medicine, acupuncture was applied at Xinshu (BL 15), Xuehai (SP 10), Geshu (BL 17), Danzhong (CV 17), Jueyinshu (BL 14), Ximen (PC 4) and Neiguan (PC 6) in three groups. Acupuncture was given once a day, 14 days as a session. After one session, each symptom score and total score of blood stasis syndrome were observed.

RESULTSOne patient dropped out respectively, and 23 patients in each group were included in the analysis. After treatment, the score of angina symptom and total score of blood stasis syndrome were significantly improved in three groups (all<0.01). The improvements of each score and total score of blood stasis syndrome in the high-risk group were superior to those in the low-risk group and moderate-risk group (<0.05,<0.01).

CONCLUSIONSWith the higher TIMI scores, the blood stasis syndrome is aggravated accordingly. Acupuncture combined with standardized treatment of western medicine could effectively intervene blood stasis syndrome, especially for the score of blood stasis syndrome of patients in high-risk group.

OBJECTIVE: To establish a mouse model bearing orthotopic temozolomide (TMZ)-resistant glioma that mimics the development of drug resistance in gliomas METHODS: Seventy-eight adult C57BL/6 mice were randomly divided into 6 groups ( RESULTS: The mouse models bearing TMZresistant glioma was successfully established. The cells from the high-dose induced group showed a significantly higher colony-forming rate than those from the high-dose control group ( CONCLUSIONS Progressive increase of TMZ doses in mice bearing orthotopic gliomas can effectively induce TMZ resistance of the gliomas.
