High density lipoprotein cholesterol ( HDL-C) has received extensive attention because of its cardiovascular protective effects.Recent studies showed that HDL could promote reverse cholesterol transport ( RCT ) , be anti-inflammatory and antioxidant, and induce angiogenesis. Apolipoptrotein A-I (apoA-I), the most abundant protein of HDL, plays a pivotal role in the HDL mediated-functional activities.Short peptides based on the amphiphilic alpha helix structure of apoA-I have been designed and aimed at imitating the function of apoA-I.The function and metabolism of these mimetic peptides depend on their amino acids component and sequence , and have been proved to exert protection in against cardiovascular disease , infection, inflammation and oxidative damage, metabolic syndrome and tumor.Clinical trials confirmed their benefits, but high cost put them out of the practical applications..

[Objective] To probe into the psychological health status of middle-aged intellectuals and its influencing factors. [Methods]A cluster sampling of 1 474 middle-aged intellectuals was measured by the SCL-90 table and was analyzed by the Reliability Analysis, Principal Component Analysis and Analysis of Variance. [ Results ] The measurement table is highly reliable (Cronbach a = 0.949) and the Principle Component Analysis has main factors (A -1.97) and cumulative contribution rate is 80% . [Conclusion]Marital status, income and gender are the main influencing factors of psychological healthy status in middle-aged intellectuals.

Objective To explore the expression change of death associated protein kinase(DAPK)and therapeutic time window for traumatic brain injury in rats.Method The traumatic brain injury models of rats were achieved by free drop impact model.The adult rats were randomly divided into normal control,sham-operation and TBI groups.Samples of"TBI group were acquired at the time point of2h,8h,24h,48h and 72h after brain injury.Pathological changes of injured neurons were demonstrated by H-E staining,the expression of DAPK mRNA W8.8 detected by RT-PCR,relative quantitation of neuron apoptosis Wa$detected by TUNEL.Results At the Sh after brain injury,the expression of DAPK increased evidently and neuron apeptosis Wag detected.The expression of DAPK and quantitation of neuron apeptosis reached peal[at the 24h after injury.Conclusion These obaervatiorm showed that the expression of DAPK in the cerebral tissues reached peak at the 24h after injury.The optimum therapeutic time window wag 24h after injury.

Objective To study the changes of serum CORT,SOD and LPO in large-acreage cerebral insarction(LCI) and hyperthermia patients,and observe the effect of head hypothermia on them.Methods All cases of LCI were divided into head hypothermia treatment group(group A,n=49),warm water bath and glacial saline enema treatment group(group B,n=43),and health group(control group,group C,n=30).With the methods of radioimmunoassay,hydroxylamine oxidation and thirddialdehyde,the serum CORT,SOD and LPO level in the two groups were measured on the 2nd day after hospitalization and on the 2nd day,the 3rd day and the 4th day after hyperthermia.In addition,the life quality scores of the two groups were compared.Results The serum CORT,LPO of group A and group B were higher on the 2nd day after hospitaiization than the group C(P0.05),while the SOD were lower(P

Objective To explore the relationship between the expression of CD44v6,P16 protein and the invasion and metastasis in gastric carcinoma and to investigate the correlation between the expression of CD44v6 and P16 protein.Methods Immunohistochemical methods were used to detect the expression of CD44v6 and P16 protein in 110 cases of gastric carcinoma.Results In 110 cases of gastric carcinoma,the expression of CD44v6 and P16 protein were 72.7%(80/110)and 47.3%(52/110)respectively. The high level expression of CD44v6 protein and low level expression of P16 protein were positively correlated with the TNM staging,serosa infiltration,lympho node and liver metastasis of gastric carcinoma(P

Hilar cholangiocarcinoma is a common bile duct cancer.The radical resection rate of end-stage malignancies reported in literature is about 20%.Half of the patients have lost the chance of operation at the time of care,while the average survival time in the patients who can not be operated is about six months.Therefore,for most patients,looking for a palliative treatment which can prolong the survival time is particularly important.From June 2013 to June 2014,our hospital applied iodine-125 brachytherapy,to treat 7 patients with unresectable hilar cholangio carcinoma.All the patients are still alive,the average survival time of 7 patients is 5.2 months up to now,with median survival time being 7.8 months,and longest survival time being 12 months.With good outcomes,few complications,as well as significantly prolonged survival time,iodine125 brachytherapy is regarded with broad clinical applications.

Objective:To evaluate the vestibular function of motion sickness. Method:VNG, which tests the vestibular function of horizontal semicircular canal,and CPT, which tests vestibulospinal reflex and judge proprio-ceptive,visual and vestibular status, were performed in 30 motion sickness pations and 20 healthy volunteers(control group). Graybiel score was recorded at the same time. Result:Two groups' Graybiel score (12. 67±11. 78 vs 2. 10±6. 23;rank test P<0. 05),caloric test labyrinth value [(19. 02±8. 59)°/s vs (13. 58±5. 25)°/s ;t test P< 0. 05],caloric test labyrinth value of three patients in motion sickness group exceeded 75°/s. In computerized pos-tourgrphy testing(CPT) , motion sickness patients were central type(66. 7%) and disperse type(23.3%);all of contral group were central type. There was statistical significance in two groups' CTP area, and motion sickness group was obviously higher than control group. While stimulating vestibulum in CPT, there was abnormality (35%-50%)in motion sickness group and none in contral group. Generally evaluating CPT,there was only 2 pro-prioceptive hypofunction,3 visual hypofunction, and no vestibular hypofunction, but none hypofunction in contral group. Conclusions Motion sickness patients have high vestibular susceptible, some with vestibular hyperfunction. In posturography,a large number of motion sickness patients are central type but no vestibular hypofunction, but it is hard to keep balance when stimulating vestibulum.

Background and purpose: In recent years, more and more clinical researches on the neuroendocrine carcinoma of the breast were carried out at home and abroad. Although there are quite a lot of the retrieved documents of NEBC at home and abroad, but large-scale reports are rare, besides, the epidemiology, diagnosis, treatment and prognosis were different;more research are needed to analyze NEBC. This paper mainly discussed the NEBC clinical diagnosis, treatment and prognosis. Methods: A retrospective analysis was carried out, 25 cases of Tumor Hospital Afifliated to Xinjiang Medical University from Jan. 2004 to Jun. 2013 were pathologically diagnosed as NEBC by clinical data and the follow-up. Results:The average age of 25 NEBC patients was 58.2 years old, without clinical and imaging characteristic features, immunohistochemistry staining showed that, the estrogen receptor (ER) and progesterone receptor (PR) positive rates were 76%and 64%. No one showed HER-2 strong positive. The follow-up was 9-115 months. Besides, 1-, 2-and 5-year overall survival (OS) rates were 100%, 95%and 88%, the disease-free survival (DFS) rates were 96%, 90%and 78%. Conclusion:The age of the patients with NEBC in this study was lower than the data abroad. Age, tumor size, pathological staging may be related to the prognosis of NEBC, and postoperative comprehensive treatment options need further study.
