AIM:To explore the clinical value of combined detection of C-reactive protein ( CRP ) , erythrocyte sedimentation rate ( ESR) and white blood cell ( WBC) count in patients with ocular syphilis.
METHODS:Dates of CRP, ESR, WBC, TPPA and RPR of 51 ophthalmopathy patients caused by syphilis and 50 normal control from Jan. 2012 to Dec. 2015 in eye hospital were recruited and analyzed statistically.
RESULTS:The positive rates of CRP, ESR and WBC of oculopathy patients were 16%, 18% and 39%, respectively, which were higher than those in the control group. In patients group, the positive rate of ESR was higher than CRP and WBC. There were no obvious relationships between RPR titers and positive ratios of CRP, WBC and ESR.
CONCLUSION: The blood level of CRP, WBC and ESR may have certain help in estimating and monitoring condition of patients with ocular syphilis.

The enantioseparations of 38 racemates on Chiralcel OD, Chiralpak AD, Chiralpak IA and(S, S)-Whelk-01 were presented by HPLC. Those enantiomers come from the amines, alcohols, ethers, ketones, aromatic derivatives, heterocyclic compounds, amide acids and medicines etc. With the mobile phase of n-hexane)/isopropanol(90∶ 10, V/V), n-hexane/isopropanol/trifluoracetic acid(90∶ 10∶ 0.2, V/V) or n-hexane/isopropanol/triethylamine(90∶ 10∶ 0.2, V/V), over 70% enantioseparations were obtained for OD, AD and IA columns). The order of enantioseparation selectivity for four columns was OD>AD>IA>(S,S)-Whelk-01, and among those columns there was a big chiral discriminating complementarity. This investigation was useful for choosing chiral columns to separate chiral compounds.

Epimutations are errors in the normal process of epigenetic regulation which can result in aberrant transcriptional silencing of a normally active gene or reactivation of a normally silent gene.Epimutations are generally considered to be somatic events and to be confined in affected tissues.However, recent studies of patients with hereditary nonpolyposis colorectal cancer(HNPCC) have showed that allele-specific hypermethylation of CpG islands in the promoter region of the MLH1 gene, one of the causes of the tumor,existed in all the tissues examined.In addition,germ-line epimutations of other tumor suppressor genes(TSGs),such as MSH2 and BRCA1,have also been reported,demonstrating that epimutations might arise in the germline(during gametogenesis or early embryonic development).The role of germ-line epimutations might be as important as germ-line mutations in human disease.We reviewed the update on germ-line epimutations of TSGs including the possible mechanisms underlying germ-line epimutations,the possibility of transgenerational inheritance.and their impact on our understanding of human disease.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

We predicted the anti-hepatitis B virus (HBV) active components and mechanism of Salvia miltiorrhiza based on network pharmacology. The active components of S. miltiorrhiza were obtained through TCMSP, PubChem database and literature research. The potential targets of the active components and HBV infection were predicted by SwissTargetPrediction and GeneCards databases, respectively. The protein-protein interaction (PPI) network was constructed by String database. Cytoscape software was adopted to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using DAVID platform. The molecular docking of key components and core targets was carried out by AutoDock Vina software. We screened out a total of 38 active components and 178 disease-component overlapping targets. Enrichment analyses obtained 405 related GO items and 68 signaling pathways, such as T/B cell receptor signaling pathways, PI3K/AKT signaling pathway, and mTOR signaling pathway. According to the results of molecular docking, most characteristic components of S. miltiorrhiza (miltionone Ⅱ, miltirone, protocatechuic acid, lithospermic acid, protocatechualdehyde) showed good affinity with the key targets (PIK3CA, APP, STAT3,AKT1 and mTOR). Furthermore, the anti-HBV activity of lithospermic acid, the representative active component of S. miltiorrhiza, and its regulation on PI3K/AKT and mTOR signaling pathways were investigated in an HBV replicating mouse model. Animal welfare and experimental procedures follow the regulations of the Animal Ethics and Welfare Committee of Hubei University. The results showed that lithospermic acid significantly inhibited HBV DNA replication, reduced serum HBsAg and HBeAg levels, and decreased the phosphorylation protein expression levels of AKT and mTOR in liver, indicating that lithospermic acid might exert the anti-HBV activity by regulating PI3K/AKT and mTOR signaling pathways.

OBJECTIVETo investigate molecular epidemiologic features of rotaviruses circulating in Shanghai, China.

METHODSStool samples were collected from 1230 hospitalized children with community-acquired and nosocomially acquired diarrhea in Children's Hospital Affiliated to Fudan University between November 1, 1999 and December 31, 2001. Polyacrylamide gel electrophoresis (PAGE) was used to detect rotavirus genomic RNA and identify electropherotypes of group A rotavirus RNAs. Reverse transcription polymerase chain reaction (RT-PCR) was performed to amplify full length VP7 gene and dot blot hybridization was performed to identify rotavirus G serotypes using digoxigenin-labelled variable regions from VP7 genes as probes. These probes were amplified by PCR from recombinant plasmids containing full length G1, G2, G3 and G4 VP7 genes from rotavirus field strains detected in Beijing and digoxigenin labelled dUTP was integrated into the PCR products. The Kruskal-Wallis analysis of variance was employed to analyze whether there were significant differences in variables.

RESULTSOut of 1230 samples investigated, 493 (40.1%) were group A rotavirus gene positive by PAGE, among which 397 (80.5%) showed long electropherotypes, 55 (11.2%) showed short electropherotypes, 18 (3.7%) showed mixed electropherotypes which suggested that the children were co-infected by rotaviruses with different electropherotypes, 23 (4.7%) were non-typable because of degradation of some of the genomic RNA fragments. No group B or group C rotavirus was found. RT-PCRs were performed for 328 fecal specimens containing sufficient rotavirus RNAs and VP7 gene products were obtained from 254 (77.4%) samples. Dot blot hybridization showed serotype G1 accounted for 55.5% (141) of these samples, serotype G3 accounted for 27.6% (70), serotype G2 accounted for 9.4% (24), co-infection by 2 rotaviruses with different G types accounted for 6.3% (16), only 1 G4 was detected and 2 were non-typable. The genomic RNA patterns of all G2 strains were short and those of G1, G3 and G4 strains were long. There were no statistically significant differences for age distribution and clinical manifestations among those infants and children infected by rotaviruses with different G serotypes.

CONCLUSIONGroup A rotavirus is the major pathogen for diarrhea in infants and children in Shanghai during the period of Nov. 1999 to Dec. 2001. Rotaviruses with long electropherotype were dominant during these years. Serotypes G1 to G3 constituted 98.8% of all 254 strains tested, and G1 was the most common serotype followed by G3 and G2, whereas serotype G4 was seldom found. Some of the children were co-infected by rotaviruses with different G serotypes. Clinical manifestations were not related to the infecting rotavirus with different G serotypes.
