Objective According to the level of serum cystatin C (Cys-C)in patients with multiple myeloma (MM),to explore its significance of early assessment to renal damage.Methods To select 42 patients with MM(MM group) and 30 healthy subjects(control group),and measure serum Cys-C,creatinine (SCr) and β2-microglobulin (β2-MG).Results The level of serum Cys-C in MM group was significantly higher than that in control group [(2.34 ± 0.57) mg/L vs.(0.66 ± 0.12) mg/L],which increased with ISS stage[Ⅰ,Ⅱ,Ⅲ stage was(1.77 ± 0.38),(2.11 ± 0.46),(3.14-± 1.07) mg/L](P< 0.05).Cys-C and β 2-MG,renal function had a positive correlation (r =0.760,0.694,P < 0.05).Conclusion The increasing of Cys-C in MM patients is related to impaired renal function and tumor burden,which can be used as an early assessment indicators.

ObjectiveTo investigate the effect of Puerarin on expression of inductible nitric oxide synthase (iNOS) in RAW264.7 macrophage cells induced by lipopolysaccharide (LPS). MethodsThe protein and mRNA levels of lipopolysaccharide (LPS)-induced iNOS was determined in RAW264.7 macrophage cells using Western blotting and RT-PCR respectively. ResultsPuerarin inhibited expression of iNOS concentration dependently (P<0.01). ConclusionPuerarin may reduce iNOS level, result in prevention of inflammation.

Objective To explore the peripheral blood microRNA (miRNA) expression of patients with gastric cancer,and to establish specific peripheral blood miRNA expression profile of gastric cancer,which would provide the evidencc for investigating the role of miRNA in the genesis and development of gastric cancer and looking for new molecular markers of gastric cancer.MethodsA total of 6 gastric cancer patients and 6 healthy volunteers were selected.The totat RNA of peripheral blood was extracted for miRNA expression profile examination and hioinformation analysis. The results of microarray were verified by real-time PCR. The online miRNA target gene pr(e)diction software was used to predict and screen miRNA differentially expressed target genes. Results Compared with control group,there were 54 differentially expressed miRNA in gastric cancer group,of which the expression of 35 miRNA (miRNA-504,mi RNA-183,miRNA- 938,miRNA-1285,miRNA- 576-3p,miRNA-663,etc) were up-regulated and 19 miRNA (miRNA-433,miRNA-193b,miRNA-329,miRNA 409-3p,miRNA 154,el(e)) were down-regulated.The results of real-time PCR indicated that there was a good consistency between PCR verificd results and microarray results in 2 up-regulated miRNA (miRNA 504 and miRNA-183) and 2 down-regulated miRNA (miRNA-443 and miRNA- 193b).ConclusionThere is specific peripheral blood miRNA expression profile of patients with gastric cancer,and these differentially cxpressed miRNA will likely become new diagnostic biomarkers of gastric cancer.

The drugs such as sildenafil adulterated in herbal products and dietary supplements may endanger human health. The number of the new modified derivatives is increasing recently. Based on Q-TOF-MS, a new sildenafil analogue was found. It was isolated and purified by preparative liquid chromatography. Its structure was determined by NMR, as 1-[4-propoxy-3-(6, 7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4, 3-d] pyrimidin-5-yl)phenylsulfonyl]-4-methylpiperazine. Compared with sildenafil, the ethoxy group of the benzene ring moiety was moved to the propoxy group, which had not been reported in China. The mass spectrometric behavior pattern of the structure type was summarized, which can greatly accelerate the structural analysis of novel analogues.

Objective To observe the specific changes of content of cyclic guanosine monophosphate (cGMP) around meridian skin and specific influences of electroacupunture Neiguan (PC6) on cGMP of rats with acute myocardial ischemia (AMI). Methods With 6 male Wistar rats as normal group, 18 rats were made AMI model and divided into model group, high-frequency group and low-frequency group (n=6). The high-frequency and low-frequency group were given electroacupuncture in bilateral PC6 with 100 and 2 Hz for 20 min respectively. The content of cGMP in skin around PC6, Ximen (PC4), Tianquan (PC2), Waiguan (TE5) and Zusanli (ST36) was detected by using enzyme-linked immunosorbent method after treatment. Results In model group, cGMP content increased significantly around PC6, PC2, TE5 and ST36 compared with normal group (P <0.05,P <0.001). After the treatment with high-frequency or low-frequency electroacupunture in PC6, cGMP content decreased significantly in skin around PC6, PC2, TE5 and ST36 compared with model group (P <0.05, P <0.001). Conclusion High-frequency electroacupunture or high-frequency electroacupunture used in PC6 can protect rats from the injury of AMI. The mechanism may be related to the decrease of cGMP content around the acupoint areas in heart-related meridian.

Objective Different grades of glioma lead to different clinical course,treatments and prognosis,thus it is important to predict histological grades of glioma preoperatively.18F-FDG PET/CT imaging and MR perfusion imaging is considered a promising method to evaluate glioma,and the present study was to evaluated the contribution of 18F-FDG PET/CT imaging and MR perfusion imaging in grading intracranial glioma.Methods Eighteen consecutive patients with suspected primary brain glioma underwent 18F-FDG PET/CT scanning and MR perfusion scanning in our hospital.To evaluate the relative sensitivity among standardized uptake value (SUV),L/W,and rCBV,the PET/CT imaging were analyzed,and the SUV and Lesion-to-white matter ratio (L/W) were calculated.The rCBV ratios of lesions were calculated relative to the region of interest (ROI) values in contra lateral normal white matter.Results Eighteen brain gliomas were confirmed by pathologic diagnosis,including 7 WHOⅡ tumors,6 WHOⅢ tumors,and 5 WHOⅣ tumors.SUV and rCBV could not differentiate between WHOⅡ tumor and WHOⅢ tumor,however significant difference could be found among the three using L/W.Conclusion 18F-FDG PET/CT imaging and MR perfusion imaging could offer more diagnostic information than conventional MRI.All of the three semiquantitative data offer some contribution in grading intracranial gliomas,and L/W might be the best one.

Objective To understand the clinical features of acute renal failure(ARF)as the initial presentation of systemic lupus erythematosus(SLE).Methods Eight cases of ARF in SLE from Jan 1995 to Apt 2006 were investigated,descriptive analysis and literature review were performed.Results①The symp- tom of ARF in SLE was mainly oliguria,with severe accompany symptoms and complications.②The level of leucocyte and hemoglobin was low in laboratory tests,also the complement level decreased significantly.The most frequent renal pathology was typeⅣ,Ⅳ+ⅤLN.③Large dose steroid and CTX were the mainstay of treatment.In addition,SCUF,CVVHDF and hemodialysis could be used for lethal conditions.Conclusion ARF can be the first manifestation of SLE and it usually represents more severe disease and more complica- tions.Large dose steroid and CTX can improve prognois.In cases refractory to steroid and if the effect is obso- lete,CTX treatment SCUF,CVVHDF and hemodialysis can be use.
