OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).

METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.

RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.

CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.

Objective To investigate the expressions of CD147,MMP-9 and TIMP-1 in human gliomas and analyze the correlations.Methods Expressions of CD147,MMP-9 and TIMP-1 were assessed in paraffin-embedded specimens collected from 78 gliomas and 12 benign brain lesion tissues by immunohistochemistry.Real time PCR was performed to detect CD147 mRNA expression.Results The positive rates of CD147,MMP-9 and TIMP-1 expression were 62%(48/78),71%(55/78),59%(46/78) respectively.We found a significant positive correlation between CD147,MMP-9,TIMP-1 expressions and poor gliomas differentiation by Spearman analysis(rs=0.2671-0.5631,Ps＜0.01).There was also a significant positive correlation between CD147 and MMP-9 expression(rs =0.3576,P＜0.01).In addition,the expressions of CD147(47% vs.80%,x2=9.510),MMP-9(56% vs.89%,x2=10.702),and TIMP-1(49% vs.71%,x2=4.138) were significantly higher in advanced gilomas than early gliomas(Ps＜0.05).The relative expression levels of CD147 mRNA in gliomas of Ⅰ to Ⅳ pathological grades were 0.15,0.27,0.46,0.78 respectively.Conclusion The expressions of CD147,MMP-9 and TIMP-1 were important characteristic of gliomas,which may serve as biomarkers in the glioma prognostic prediction.

OBJECTIVETo explore the active ingredients in the Chinese yellow wine could inhibit the proliferation and migration of rat vascular smooth muscle cells induced by homocysteine (Hcy).

METHODSThe primary culture and identification of rat vascular smooth muscle cells (VSMCs) was conducted, and the VSMCs in passage 4-7 were used in the following experiments. The VSMCs were divided into 7 groups: control, Hcy (1 mmol/L), Hcy + oligosaccharide, Hcy + polypeptides, Hcy + polyphenols, Hcy + alcohol, Hcy + Chinese yellow wine and were given the corresponding treatment. The proliferation of VSMCs was determined by MTT. Transwell chambers and would healing were employed to test the migratory ability of VSMCs. Wester blot and gelatin zymography were used to investigate the expressions and activities of metal matrix proteinase 2/9 (MMP-2/9) and tissue inhibitor of metalloproteinase 2 (TIMP-2) in VSMCs of each group.

RESULTSCompared with control group, the proliferation, migration and the expression and activity of MMP-2/9 of VSMCs were significantly increased in the VSMCs of Hcy group (P < 0.01). Compared with Hcy group, the proliferation, migration and the expression and activity of MMP-2/9 of VSMCs were significantly decreases in the VSMCs of polypeptides group, polyphenols group and Chinese yellow wine group. However, the expression of TIMP-2 among each group had no significant difference.

CONCLUSIONPolypeptides and polyphenols in the Chinese yellow wine could inhibit the proliferation and migration of VSMCs induced by Hcy.

OBJECTIVETo evaluate the efficacy of combined vaccination with 200IU dose of HBIG and 20 μg of anti-HBV vaccine for the prevention of HBV vertical transmission in babies delivered by HBeAg + and highly viremic mothers and the HBV markers' dynamic changes in babies during follow-up.

METHODSHBeAg + mothers with HBV DNA ≥ to 1.0 × 6 log(10) copies/ml were enrolled and their babies were followed up until 12 months old. The infants received HBIG 200 IU IM in 24 hrs and on day 15, and 20 μg recombinant anti-HBV vaccine at 0, 1 and 6 months. The HBV markers and HBV DNA were tested at birth day, and 1, 7, 12 months after birth respectively. The vertical transmission rate at birth and intrauterine infection rate, the HBsAb positive rate and the HBV markers' dynamic changes during follow up were evaluated.

RESULTS(1) 29 out of 127 infants with HBsAg (+) at birth, 11 of which were HBV DNA (+), HBV perinatal transmission rate was 22.83%. 2 infants' HBsAg were positive at month 1 and became negative at month 7 and 10 infants were still HBsAg (+) and HBV DNA (+). HBV intrauterine infection rate was 7.87%. (2) The positive rate of HBeAg and HBcAb in uninfected infants were 96.58% and 98.29% respectively, which declined gradually to undetectable level after immunization. No infants were HBeAb (+). (3) Infants uninfected produced effective HBsAb after vaccination. The level of HBsAb elevated gradually, and the level of HBeAg decreased quickly even to undetectable.

CONCLUSIONThe combination vaccination of 200 IU HBIG with 20 μg recombinant anti-HBV vaccine in the Infants delivered by HBeAg (+) and highly viremic mothers reduced obviously the rate of perinatal transmission of HBV, enhanced largely the production of antibody against HBV surface antigen and dropped the maternal HBeAg and HBcAb in infants or even to negative.

It is an important influencing factor that the generated wear particles lead to periprosthetic osteolysis after artificial joint replacement. Current research suggests that the primary cause of wear particles results in periprosthetic osteolysis is relate to the prosthetic materials and the stimulations because of these materials generated wear particles to relevant cells such as macrophage, osteoblast, osteoclast. Induced a variety of inflammatory cytokines, activating and openning the cell signal and channels, producing the long term chronic inflammation leads to periprosthetic osteolysis. Therefor, the paper mainly studies the different types of wear particles influence on periprosthetic osteolysis, and the wear particles around the periprosthetic osteolysis mechanism in the process of progress, moreover, to explore how to reduce the occurrence of wear particles and blocking its role in the periprosthetic osteolysis, in order to achieve the purpose of prevention and treatment of periprosthetic osteolysis.

OBJECTIVETo study the effect of alternatively activated macrophages /mononuclear phagocytes(MNP) on breast cancer cells and explore the mechanisms for the action of tumor-associated macrophages in breast cancer.

METHODSHuman peripheral blood monocytes were isolated and cultured in vitro and divided into 3 groups, namely classically activated monocytes (CAM) which were induced by lipopolysaccharide, alternatively activated monocytes (AAM) induce by IL-4, and control cells treated with the culture medium only. After cell culture for 48-72 h, the mRNA of tumor necrosis factor-alpha (TNF-alpha), alternative monocytes activation- associated CC-chemokine 1 (AMAC-1), and beta-actin of the 3 groups were extracted for RT-PCR, or the cells were cocultured with breast cancer cell line SKBR3, or seeded in chicken chorioallantoic membrane along with SKBR3.

RESULTSTNF-alpha mRNA was significantly increased in CAM, and AMAC-1 was highly expressed in AAM. The coculture experiments showed that CAM exhibited obvious inhibitory effect on SKBR3 cells after a 3-day culture whereas AAM significantly promoted the growth of SKBR3 cells after a 5-day culture. In chicken on chorioallantoic membrane experiment, the macrophages promoted tumor angiogenesis and AAM showed the most obvious effect.

CONCLUSIONIL-4 induces high expression of AMAC-1, a molecular marker of AAM, in the macrophages, and AAM can promote the growth of SKBR3 cells and tumor angiogenesis.

OBJECTIVETo ascertain the genetic characterization and genotype of measles viruses isolated in Shanghai region, in 2005.

METHODSMeasles virus was isolated from throat swab specimens collected from suspected measles cases and 450 bp fragment of C terminus of nucleprotein (N) gene was amplified by RT-PCR. Sequence analysis was conducted to ascertain the genotype and to compare the difference of nucleotide with other measles virus strain published in GenBank.

RESULTS4 measles viruses were isolated from 10 throat swab specimens, and the sequence analysis indicated that they belonged to H1 genotype. The homogeneity of 450 nucleotides in the C terminal of the N gene was at 98%-98.2% as compared to H1 genotype (China93-7). They differed from genotype H2 (China94-1) at 6.4%-6.9% and from genotype A (Edmonston) at 6.7%-6.9%, from measles vaccine (Shanghail91) at 7.6%-8.0%. They differed from the other measles viral strain isolated in China in 1993 - 2005 at 0.2%-3.7%. The variation within 4 isolated measles viruses was at 0.7%-1.3%.

CONCLUSIONIt was H1 genotype measles viruses,which are the native viruses in China that led to the outbreak of measles in Shanghai, in 2005.

OBJECTIVETo analyze the type and subtype distribution of influenza virus and the genetic evolution of hemagglutinin (HA) in Shanghai area during 2004 to 2008.

METHODSAll 962 throat swabs were collected from influenza-like patients in 5 influenza sentry hospitals and influenza outbreaks. Influenza viruses were isolated in MDCK cell lines, and then viral types and subtypes were identified. The HA of influenza A isolates selected by outbreak or sporadic patients in different areas and epidemic seasons were sequenced and analyzed by phylogenetic trees.

RESULTSA/H3N2, accounting for 54.9% (162/295), was the dominate subtype in recent years, but less popular in the end of 2005 to the middle of 2006 with 0% (0/16)and 23.5% (8/34) of positive specimen, respectively. There were more A/H1N1 isolates in 2005 - 2006 with 21.4% (12/56), 43.8% (7/16) and 76.5% (26/34) of positive specimen, respectively, but declined obviously in 2007 - 2008 accounting for only 0% (0/44) and 5.0% (7/139). Influenza B virus was more popular in 2004 to 2005 with 42.9% (24/56) and 56.2% (9/16), respectively, and not isolated from 2006 to 2007, then increased in 2008 accounting for 34.5% (48/139). Phylogenetic tree of HA showed that A/H1N1 isolates in the same year clustered from 2005 to 2008, and most A/H3N2 isolated were homologous in the same year during 2004 - 2008 while some were inserted to the clusters of near years and more distinguished sequences appeared. A/H1N1 and A/H3N2 isolates were all similar to the vaccine strains recommended by WHO.

CONCLUSIONThe distribution of influenza type and subtype kept on changing each year, but A/H3N2 dominated in most years. A/H1N1 and A/H3N2 in the same year clustered, but some A/H3N2 of near years were and evolved faster with more distinguished strains appeared in same interval. Generally, HA of influenza A isolates in Shanghai during 2004 to 2008 were similar to the WHO reference strains.

OBJECTIVEIn order to obtain functional genes, a normalized stems cDNA library was constructed from medicinal plant Dendrobium officinale.

METHODSMART (switching mechanism at 5' end of RNA transcript) cDNA synthesis combined with DSN (duplex-specific nuclease) normalization was applied to construct the normalized full-length cDNA library of D. officinale.

RESULTThe titer of cDNA library was about 1.3 x 10(6) cfu x mL(-1) and the average insertion size was about 1.5 kb with high recombination rate (93.9%). Random selected 163 positive clones were sequenced at single side. Bio-information analysis indicated that 147 from 150 high-quality unique sequences matched corresponding homologous proteins, and they participated in various biological processes based on GO (gene ontology). There were 8 clones with complete coding sequence, which presumed to be full-length genes.

CONCLUSIONThese results showed preliminarily that we successfully constructed a normalized full-length cDNA library of D. officinale which could be used to screen the functional genes related to metabolic pathways of medicinal ingredients.
