Type 2 diabetic patients are usually accompanied by dyslipidemia.The cardiovascular residual risk is still high in these patients,even with glycemia,blood pressure,and plasma lipids well controlled.In this review,the relationship of plasma lipids and changes in lipoprotein particles with cardiovascular risk is discussed.

PTEN gene is considered to be the first discovered tumor suppressor gene with dual specificity phosphatase activity.The research has shown that the increasing popularity of PTEN rests on its important roles in cancer cell growth,differentiation,signaling transduction and cell apoptosis.Besides,the mutation of PTEN is related to cancer initiation and progression.The recent advances on PTEN gene in malignant tumors will be reviewed in this paper.

Objective To explore relationship between magnetic resonance imaging (MRI) performance and lipid levels in pa-tients with lacunar infarction (LI) .Methods 68 patients with LI were retrospectively analyzed ,62 cases patients without heart ce-rebrovascular disease in the same period were choosen as control group ,the multivariate logistic regression was used to analyze the relationship between MRI performance ,the changed level of lipid .Results A total of 299 lacunar lesions were detected by MRI ,in which there were 58(19 .40% )in the left cerebral hemisphere ,26(8 .70% ) in the right hemisphere ,73(24 .41% ) in the bilateral basal ganglia ,27 (9 .03% ) in thalamus ,54 (18 .06% ) in the lateral ventricles corona radiata ,39 (13 .04% ) in brainstem ,and 22 (7 .36% ) in cerebellum .TC ,TG ,LDL-C and Ox-LDL levels in LI patients were significantly higher than the controls (P<0 .05) , while HDL-C levels were significantly lower than the controls (P<0 .05) .Multivariate Logistic regression analysis showed that relative risk of TC ,TG ,LDL-C ,HDL-C and Ox-LDL to LI were 1 .56 ,1 .27 ,1 .39 ,1 .46 and 1 .44 .Conclusion The MRI manifestations and lipid levels of LI have a certain degree of correlation ,and elevated blood lipid levels may be important risk factors for LI .

Objective:To study the variation of X chromosome centromeric Alpha Satellite DNA in Klinefelter's syndrome patients,their parents and normal individuals and to discuss the mechanism of Klinefelter's syndrome X chromosome nondisjunction.Methods:The multi-copies of a 2Kb tandem repeat unit on X chromosome of centromeric Alpha Satellite DNA were simultaneously amplified with reasonable primers by (representative sampling of multiple repetitive units,rep)PCR,and the mechanism of X chromosome aneuploidy resulted by abnormal structure of centromere was investigated.Results:1774bp,570bp and 1410bp,583bp,220 bp (three short fragments are resulted by deletion in alpha satellite DNA) were detected in Klinefelter's syndrome patients,their parents and normal karyotype controls.There were 1774bp and 1410bp DNA fragments in all of samples.The relative frequencies of 570bp and 583 bp were significantly higher in Klinefelter's syndrome patients than in normal karyotype controls,the 220bp was not found significantly different in the three groups.Conclusion:Deletion in the region of Alpha Satellite DNA is present at centromeres of all human X chromosome,while Klinefelter's syndrome patients and their parents show higher frequency than normal individuals.These results imply that analysis of deletion on X-specific ?satellite of the parents during the pre-pregnancy and pregnancy plays a important role either in estimating the risk of repruducing Klinefelter's syndrome or in providing the guideline for prenatal chromosome diagnosis of villus and amniotic fluid.

Objective To investigate the influence of genistein(Gen) on the growth and apoptosis regulation of hepatoma carcinoma cells SMMC-7721.Methods SMMC-7721 cells were divided into three Gen groups treated with different concentrations(5.0,10.0,20.0 mg?L-1) and control group(without Gen).After SMMC-7721 cells were treated for 24 and 48 h,the changes of ultrastructure of cells were observed under electron microscope, MTT was used to detect the inhibitory rate of proliferation of SMMC-7721 cells,flow cytometry was performed to analyze cell phase;immunohistochemistry was used to detect the expression of Caspases-3 protein.Results Compared with control group,chromatin in cellular nucleus became conglomeration or lumping,with chondriosome swelling in Gen groups.With the increasing of Gen concentration,the cellular nucleus became condensed,heterochromatin agglutinating,ground cytoplasm obviously cavitating;with the increase of Gen concentration and prolongation of time,from 24 to 48 h,MTT showed the inhibitory rate of proliferation of SMMC-7721 cells increased in a time-and dose-dependent manner.Flow cytometry analysis showed that with the increase of Gen concentration,the number of cells at G2/M phase increased,the number of cells at S phase decreased and the ratio of G0/G1 also decreased.Immunohistochemistry results showed the expression of protein Caspases-3 increased with the Gen concentration in a dose-dependent manner(P

Due to the influence of potential psychological trauma, athletes in the competition may repetitively suffer poor performances, such as losing his usual form, slump, choking, and so on. These under-performing problems actually are symptoms of sports post-traumatic stress disorder (SPTSD). SPTSD refers to the pathological physical and mental after-effects of a trauma previously suffered by the athlete on that athlete's subsequent performances. This is a very common physical and emotional problem in athletics that impairs athletes' performance, affecting their competition results. By peak performance eye movement desensitization and reprocessing therapy, therapists can deal with this problem effectively and help athletes eliminate symptoms of sports post-traumatic stress disorder, improving the competition performance.

The pathological changes in myocardial cell of diabetic rats were consistent with diabetic cardiomyopathy. The levels of adiponectin and the expression of T-cadherin in diabetic group were increased gradually,and higher than in normal control group

Objective To determine intra-operative changes in blood coagulation and the applicability of SCA in liver transplantation. Methods Twenty-four patients with end-stage liver disease undergoing or-thotopic Liver transplantation (OLT) were studied. Arterial blood samples were drawn for determination of celite-activated TEG, glass bead-activated SCA and RCT at 6 intervals: before anesthesia induction (T0), 60 min after operation was started (T1), 30 miu in anhepatic phase (T2), 30 min in neohepatic phase (T3) ,120 min in neohepatic phase (T4) and the end of the operation (T5) ; the variables of TEG includ-ed: reaction time(R) ,coagulation time(K), alpha angles (α) and maximal amplitude (MA) ; the variables of SCA included: activated clotting time (ACT), clot rate (CR) and platelet function(PF) ;RCT included: Plt, PT, INR, APTT, Fbg. Results The Kappa values of SCA and TEG diagnosing the deficiency of blood coagulation factors, the gel formation speed of fibrin and the function of platelet were respectively 0.371 (P < 0.05) ,0. 363 (P < 0.05) ,0.438 (P < 0.05). gbACT and R, CR and α, PF and MA were positive-ly correlative (r = 0. 790, P < 0.05 ; r = 0. 766, P < 0. 05 ; r = 0. 502, P < 0.05 ; respectively) ; CR and K were negatively correlative(r = -0. 588,P <0.05). Compared with T0, PT, INR, gbACT and R were pro-longed, FBG, CR, α and MA were decreased at T3-5 (P < 0.05). APTT was prolonged at T1 ～ T5 (P < 0.05). K was prolonged at T3 (P < 0.05) and PF was decreased at T2 ～ T4. Conclusion SCA can exactly monitor changes of blood coagulation in liver transplantation.

Endotoxemia is due to the infection of bacteria or lesions which release a lot of toxins into the blood,or the infusing of large amount of endotoxin-contaminated liquid.It can cause systemic inflammatory response syndrome,sepsis,or multiple organ dysfunction syndrome.Endotoxemia is a common and complex problem in modern emergency medicine.Early diagnosis and timely blocking not only can prevent further infection but also plays a positive role in the prevention and treatment of sepsis and its complications.In recent years,progresses have been made in the treatments of endotoxemia by hemoporfusion.The direct adsorption of endotoxin and inflammatory cytokines in blood can quickly reduce their concentration.This can not only weaken their own activity but also inhibit the release of other harmful cytokines,so as to improve the symptoms of infection.So far,the specific hishaffinity adsorbents having the clinical value are still at the exploratory stage.Although these materials were found effective in the treatments of endotoxemia,in-depth study need to be carried out on their clinical criteria in order to acquiremore satisfied results.
