Objective To investigate papillary muscle function and construction in myocardial infarction(MI) patients by two-dimensional speckles tracking imaging(2D-STI),and to analyze the influence factors of ischemic mitral regurgitation.Methods Fifty myocardial infarction with ischemic mitral regurgitation(IMR) patients were brought into case group.The patients were divided into two groups:Ant MI group and Inf-Pos-MI group.Forty-five health volunteers were involved as control group.Anterior,posterior papillary muscle longitudinal strain (ALS,PLS),delay time(DT),fractional shortening (FS),length between the posterior or anterior papillary muscle tips and the contralateral anterior mitral annualr (APM AMA,PPM AMA),mitral leaflet closure (MLC),inter distance papillary muscle (IPMD) were aquired respectively.Papillary muscle function and construction among the groups were compared,and the effective factors of IMR were evaluated.Results Between the control group and Ant-MI group,the left ventricular end-diastolic diameter(LVEDD),left ventricular end-diastolic and end-systolic volume(LVEDV,LVESV),left ventricular ejection fraction(LVEF),ALS,delay time(DT),A FS,IPMD,MLC,APM-AMA,PPM-AMA were significantly different(all P ＜0.05).Between the control group and Inf-Pos-MI group the LVEDD,LVEDV,LVESV,EF,DT,PPM-AMA,MLC,PLS,P-FS were significantly different(P ＜0.05).Between the Ant-MI group and Inf-Pos-MI group,the LVEDD,LVEDV,LVESV,EF,MLC,ALS,PPM-AMA,PLS were significantly different (all P ＜ 0.05).In the Ant-MI group,LVEDV,ALS,MLC were significantly correated with Gensini score(r =0.71,-0.65,0.56;P ＜0.05).In the Inf-Pos-MI group,PPM AMA,PLS were significantly correated with Gensini score(r =0.65,-0.76;P ＜0.05).In the Ant MI group and Inf-Pos-MI group,the ALS,PLS,PPM-AMA were significantly different (P ＜ 0.05).Its correlates in Logistic analysis of Ant-MI group included LVEDV,MLC,DT with OR 1.48,1.72,1.54(P ＜0.05),respectively.Its correlates in logistic analysis of Inf Pos-MI group included PLS,PPM-AMA,DT with OR 1.78,1.57,1.56 (P ＜0.05),respectively.Conclusions There are different extent of damage of papillary muscle function and construction in Ant-MI group and Inf-Pos-MI group.The increases of LVEDV and MLC and desynchronization of PMs are risk factors of IMR in Ant-MI group.The increases of PMP-AMA,decrease PLS and desynchronization of PMs are risk factors of IMR inInf-Pos-MI group.

Purpose To evaluate papillary muscle function in ischemic mitral regurgitation (IMR) with two-dimensional speckle tracking imaging (2D-STI) and three-dimensional ultraphonic technology,and to investigate the primary factors influencing IMR so as to provide clinical information for the prediction of IMR.Materials and Methods Seventy-six IMR patients were enrolled as research group and other 66 healthy volunteers as control group.Two groups were both examined by transthoracic echocardiography and 2D-STI.The parameters including fractional shortening of anterior and posterior papillary muscles (AFS,PFS),length of anterior or posterior papillary muscle tips to contralateral anterior mitral annular (APM-AMA,PPM-AMA),mitral leaflet closure (MLC),inter distance papillary muscle (IPMD),the angle between the anterior papillary muscle and the anterior LV free wall (Ang Ⅰ) and the angle between the posterior papillary muscle and the anterior LV free wall (Ang Ⅱ),anterior and posterior papillary muscle longitudinal strain (ALS,PLS) and peak time (APT,PPT),delay time (DT),left ventricular end-diastolic diameter (LVIDD),left ventricular end-diastole volume (LVEDV),and left ventricular ejection fraction (LVEF) were compared.Results Compared with control group,LVIDD,LVEDV,LVEF,AFS,PFS,IPMD,MLC,ALS,PLS and DT in research group were all significantly different (all P＜0.05).ALS,PLS,AFS,and PFS had positive correlation with LVEF (P＜0.05) and negative correlation with LVEDV (P＜0.05).MLC,IPMD,DT had negative correlation with LVEF (P＜0.05).ALS,PLS,MLC,AFS,PFS,IPMD were significantly correlated with Gensini score (r=-0.65,-0.78,0.54,-0.51,-0.57,0.49,respectively,P＜0.05).The multivariant Logistic regression analysis showed that IMR was correlated with IPMD,MLC,PLS and DT (OR=1.26,1.32,1.37,1.52,respectively,P＜0.05).Conclusion 2D-STI can accurately evaluate the papillary muscle dysfunction caused by myocardial ischemia.Moreover,the risk factors of IMR include increase of IPMD and MLC,decrease of PLS,and desynchronization of papillary muscles.These findings contribute to the clinical prediction of IMR.

Objective To sum up the experience of renal transplantation in order to improve transplant effect and enhance the long-term survival and recovery rate.Methods The data of renal transplantation of 1 124 cases who received renal transplantation from Jul. 1978 to Oct. 2001 were summarized. All the possible factors that could influence the transplant effect such as pre-operative preparation, HLA match, donors' quality, surgical procedure, immunosuppressive therapy and so on were analyzed. Results The 1-, 3-, 5-year survival rate (%) of patient/kidney was 83.1/ 70.3, 74.6/ 68.6 and 62.6/ 56.1 respectively. The rate of AR was decreased significantly from 3.09?% only with LXM to 0.89?% with LXM test in combination with HLA serological test. The rate of HAR and AR in 130 cases with additional PRA test were lower than those only with LXM test.Conclusions The well pre-operative preparation, the ideal HLA match, the high quality of donor's kidney and transplant operation were keys for successful renal transplantation. Reduction of the complications, individual and combined medication in reason and long-term follow-up were very important in the long-term survival time.

Objective: To investigate the laboratory,clinical and economic results of early postoperative enteral nutrition(EEN) in patients with gastrointestinal cancer.Methods: 120 patients with gastrointestinal cancer were randomly divided into three groups: EEN,early postoperative parenteral nutrition(PN), and traditional nutrition(CON)groups.The 1/3 and 2/3 target volumes were administered on the first and second postoperative days(1POD,2POD),and the full volume was given from 3POD to 8POD in EEN and PN groups.The routine formula was offerd from 1POD to 8POD in CON group.The nutritional and immune parameters were detected one day before surgery and 9POD, and the clinical and economic results were collected in three groups.Results: The levels of ALB,TF,PA,CD3,CD4,CD4/CD8 were significantly higher in EEN and PN groups than those in CON group(both P＜0.01),and the CD3,CD4,CD4/CD8 were better in EEN group than those in PN group(P＜0.05).The side effects of EEN group were similar to those of PN group(P>0.05). The recovery of bowel function was quicker in EEN group than that in PN and CON groups(both P＜0.05).The complication rate, cost of nutrition support,and cost of complication treatment were lower in EEN group than those in PN group(P＜0.05, P＜0.01, P＜0.01).Although the cost of nutrition support was lowest but the complication rate and cost of complication treatment were all highest in CON group.Conclusion: EEN is better in immune function, recovery of bowel function,complication rate, and cost-effectiveness than those in PN, and from our multiple angular viewpoints EEN is the first choice for patients with gastrointestinal cancer.

OBJECTIVETo evaluate digital rectal examination (DRE) , transrectal ultrasonography (TRUS) , free/total (f-PSA/ t-PSA) prostate-specific antigen (PSA), and PSA density (PSAD) in the diagnosis of prostate cancer (PCa) in patients with PSA < or = 4.0 microg/L.

METHODSBetween April 1996 and December 2012, a total of 343 subjects, aged 30 -91 years, with PSA < or =4.0 microg/L and abnormal findings on DRE or TRUS underwent prostatic biopsy. Based on the levels of PSA, the subjects were divided into four groups: 0 -1.0, 1.1 -2. 0, 2.1 -3. 0, and 3.1 -4.0 microg/L. The diagnostic values of DRE, TRUS, f-PSA/t-PSA, and PSAD were assessed in those with different PSA levels. According to the age, the subjects were again divided into five groups: C49 yr, 50 -59 yr, 60 -69 yr, 70 -79 yr, and > 80 yr. The rates of PCa detection in relation to PSA levels were estimated in different age groups.

RESULTSOf the 343 subjects, 65 (19.0% ) were diagnosed with PCa, with detection rates of 16.28% (21/129) , 17. 17% (17/99), 21.82% (12/55), and 25.00% (15/60) in those with the PSA levels of 0 -1.0, 1.1 -2.0, 2.1 -3.0, and 3.1 -4.0 microg/L, respectively. There were statistically significant differences in f-PSA/t-PSA between the PCa patients and non-PCa subjects with the PSA level > 2.0 microg/L (P <0.05) , but not with the PSA level < or =2.0 microg/L (P > 0.05) , nor did PSAD show any significant difference between the PCa and non-PCa groups ([0.09+/-0. 16] versus [0. 06 +/- 0. 07] micro/L/ml, P > 0. 05). The rate of cancer detection rose -with the elevation of the PSA level, but had no statistically significant difference among different age groups (P >0.05).

CONCLUSIONPSA 2.1 -4.0 microg/L with abnormal DRE and TRUS findings should be considered as a warning signal, which requires regular follow-up and PSA detection. With f-PSA/t-PSA <0. 15 with or without abnormal DRE and TRUS findings, routine prostate biopsy should be performed. PCa diagnosis cannot be effectively established by DRE, TRUS, f-PSA/t-PSA, and PSAD in those with PSA < or = 2.0 microg/L.

microRNAs (miRNAs) are short non-protein-coding RNAs,which play important roles in the cell proliferation,differentiation,apoptosis,as well as activation of oncogenic and antioncogenic signals.Researches show that the abnormal expressions of miRNAs are closely related to the tumorigenesis,histological type,diagnosis,treatment and prognosis of lung cancer.So miRNAs may be the most potential and promising therapeutic targets for lung cancer.
