Objective To explore the effect ot atorvastatin on the levels of serum Interleukin-6 ( IL-6),Endothelin(ET) and MCP-1 in patients with acute cerebral infarction(ACI).Methods 100 patients with ACI were randomly divided into the atorvastatin therapy group(n =50) and the conventional therapy group(n =50).At the basic of conventional therapy,the atorvastatin therapy group was treated with Atorvastatin 20mg/d.Both groups were treated for 4 weeks.The levels of serum IL-6,ET and MCP-1 were measured and the scores of neurological deficit ( NDS ) were evaluated before and after treatment.A healthy control group which approximately matched the experimental group included 30 persons.Results The levels of serum IL-6,ET and MCP-1 in both two groups after 14d treatment were significantly lower than those before treatment(t =26.38,49.10,34.51,25.77,32.23,34.68,P ＜0.05),and the levels of serum IL-6,ET and MCP-1 in atorvastatin therapy group was significantly lower than that in conventional therapy group( t =10.10,13.18,23.85,P ＜0.05 ).NDS of both groups after treatment was lower than those before treatment(t =18.38,6.98,P ＜0.05 ),and the score of atorvastatin therapy group was significantly lower than that of conventional therapy group( t =12.00,P ＜ 0.05).Conclusion Atorvastatin could significantly decrease the levels of serum IL-6,ET and MCP-1,and it could promote the neurological fuction recovery in the patients with ACI.

The relationship between diabetes and osteoporosis has gradually become a new research hotspot , but is still much controversy .High concentration of blood glucose can be bond to varieties of proteins in vivo and form glycosylation end products in col -lagen tissue and reduce bone strength , besides it can inhibit RANKL induced osteoclast formation and bone resorption by repressing redox-sensitive NF-kappa B activity .A series of diabetes mellitus complications can induce less local bone nutrition supply and calcium and phosphorus sorption , reduce muscle tension and bone mineral density , which leads to the increase of fracture risk .Type 2 diabetes patients with overweight or obesity often have increased secretion of inflammation factors , adiponectin and leptin , which promotes the formation of osteoclasts and encourages bone marrow stromal stem cells to differentiate into adipocytes ;On the other hand , adiponectin and leptin can facilitate osteoblasts proliferation , differentiation and activity , and promotes bone formation .This article will discuss how diabetes works on bone metabolism and the underlying pathophysiological and physiological mechanism .

Late-life anxiety has a high prevalence and usually co-morbidity with cerebral-and cardiovascular diseases which in turn increases the disability and mortality in old people.The pathology of late-life anxiety is difference from adult with the character of GABAergic neuroplasticity dysfunction.The therapeutic strategy presently can only alleviate the anxious symptom but not ameliorate the neuroplasticity.Brain-derived neurotrophic factor (BDNF) is a critical signaling molecule which regulates the GABAergic neuroplasticity,reduction of BDNF along with aging can induce GABAergic dysfunction which contributes to late-life anxiety.BDNF may exert anxiolytic effects by restoring the GABAergic plasticity and can be a potential therapeutic strategy of late-life anxiety.

Human herpesvirus-8 (HHV-8) also referred to as Kaposi’s sarcoma-associated herpes-virus (KSHV),is a novel tumor causing virus,which is thought to be the etiologic agent of KS,and also is associated with primary effusion lymphoma(PEL) and multicentric castleman’s disease(MCD) HHV-8 encodes a number of viral proteins, including the proteins associated with HHV-8 latent infection and lytic infection,and the proteins unique to HHV-8,which are critical players in the development of KS and HHV-8-associated diseases. The proteins encoded by HHV-8 and association between HHV-8 and KS were reviewed.

Purpose To compare radiation dose and image quality of different scan modes for CT pulmonary angiography (CTPA) including high-pitch flash mode, dual energy CT (DECT) mode, 128-slice mode of dual source CT and 64-slice CT mode. Materials and Methods One hundred and sixty-seven patients with suspected pulmonary embolism were retrospectively studied. All the patients underwent CTPA. Twenty patients were selected randomly from the patients scanned by high-pitch flash mode. Patients who were scanned by the other three modes were selected with body mass index and age matched those in high-pitch flash mode, with 20 patients in each group. Two radiologists assessed signal-to-noise ratio (SNR) and image quality with 5-piont scale. Dose parameters of volume CT dose index (CTDIvol), dose length product (DLP), and effective dose (ED) were compared among the four groups. Results Mean CTDIvol, DLP and ED were (3.72±0.74) mGy, (137.5±28.7) mGy · cm, and (2.34±0.41) mSv for Flash mode;(5.31±1.21) mGy, (181.6±34.5) mGy· cm and (3.24±0.57) mSv for DECT mode;(5.66±1.47) mGy, (198.7±42.1) mGy·cm and (3.58±0.63) mSv for 128-CT mode;and (6.75±1.68) mGy, (231.5±54.2) mGy·cm and (4.21±0.89) mSv for 64-CT mode. There was no significant difference of SNR and image quality among the four modes (P>0.05). Conclusion There are no significant difference of image quality among the four groups. Flash mode allows for minimum radiation dose compared to other modes. DECT mode and 128-CT mode get higher radiation dose with no difference between them. 64-CT mode gets the highest radiation dose.

Aim To investigate the effects of Ginkgo biloba extract(EGB)on tumor necrosis factor-alpha(TNF-?)in TNBS-induced colitis in rats and its mechanisms.Methods Colitis in rats was induced by colonic administration with 2,4,6-trinitrobenzene sulfonic acid(TNBS).Wistar rats were randomly divided into four groups,10 in each:normal group,model group,5-aminosalicylic acid(5-ASA group)and Ginkgo biloba extract group(EGB group).The levels of nitric oxide(NO),and glutathion peroxide(GSH-Px)were measured by biochemical methods.The expressions of TNF-? and nuclear factor kappaBp65(NF-?Bp65)in the colon tissues of colitis rats were detected by means of immunohistochemistry.The expressions of induce nitric oxide synthase(iNOS)in the colon tissues of colitis rats were detected by reverse transcription polymerase chain reaction(RT-PCR).The effects of EGB on colonic inflammation and macroscopic and histological damage were evaluated as well.Results Compared with the model group,treatment with EGB for 4 weeks significantly reduced colon macroscopic and histological damage,elevated the activities of GSH-Px and reduced the contents of NO,inhibited the protein expressions of TNF-? andNF-?Bp65,and decreased the mRNA levels of iNOS in the colon tissues of experimental colitis.Conclusions The probable mechanisms of EGB was that it ameliorated inflammatory injury in TNBS-induced colitis in rats by its reduction of TNF-?,NF-?Bp65 and iNOS levels.Then EGB could curb the inflammatory cascade effects of inflammatory mediators to protect ulcerative colitis.

Objective To develop a chemiluminescence imaging DNA microarray method for simultaneous,quick and accurate detection of serotypes of human adenovirus (HAdV ),namely,HAdV3,HAdV7,HAdV11,HAdV14 and HAdV55.Methods Based on the specific gene sequences in the conserved region of adenovirus from GenBank, oligonucleotide primers and probes were designed and synthesized to prepare the oligonucleotide microarray.The specific genomic sequences were amplified by multiplex PCR method.The multiplex PCR amplification products were hybridized with the specific probes of microarray that was scanned after washing and chemiluminescenceb before the result was analyzed.After optimization of the multiple PCR system,hybridization reactions and conditions of chemiluminescence,the specificity,sensitivity and reproducibility of the chip were evaluated.Results The microarray displayed high sensitivity, specificity and reproducibility.The minimum detection limit of plasmidg DNA was 3 ×103 copies/reaction.The microarray detection results of 38 clinical samples were approximately consistent with those using the direct sequencing method(37 /38).Conclusion A chemiluminescence imaging DNA microarray method for quick,sensitive and specific detection of five serotypes of HAdV is established,which can provide a new means for detecting serotypes of HAdV.
