A Diamond Electrochemical Cleaning Technique for Organic Contaminants on Silicon Wafer Surfaces

Peroxodiphosphate anion （a powerful oxidant） can be formed in a special water-based cleaning agent through an electrochemical reaction on boron-doped diamond electrodes. This electrochemical reaction was applied during the oxidation,decomposition, and removal of organic contaminations on a silicon wafer surface, and it was used as the first step in the diamond electrochemical cleaning technique （DECT）. The cleaning effects of DECT were compared with the RCA cleaning technique, including the silicon surface chemical composition that was observed with X-ray photoelectron spectroscopy and the morphology observed with atomic force microscopy. The measurement results show that the silicon surface cleaned by DECT has slightly less organic residue and lower micro-roughness,so the new technique is more effective than the RCA cleaning technique.

Expression and Identification of the Type-specific Antigen of FMDV of Serotype C

[Objective]The aim was to provide a theoretical basis for preparation of polyclonal antibodies and monoclonal antibody that of type specificity, as well as Foot-and-mouth Disease Virus （FMDV） typing.[Method] The recombinant plasmid pGEM-CP1 that contained VPI gene of FMDV of serotype C was used as template for the VP1 and its C terminus coding fragments of FMDV of serotypes C amplification. The coding fragments of VP1 and its C terminus were respectively cloned into prokaryotic expression vector for prokaryotic expression and the reactionogenicity was detected. The purified fusion protein of FMDV VP1 and its C terminus of serotype C were used to construct the indirect ELISA method to detect positive sera of four serotypes A, O, C and Asia 1 of guinea pig and determine the cross reactivity of FMDV antibody of VP1 and its C terminus of serotype C with other three serotypes. [ Result] The recombinant prokaryotic expression plasmids of PPRO-CVP1 and pPRO-CVPlc were constructed, FMDV VP1 and its C terminus of serotype C were expressed in high level, and the molecular weight of target proteins was 33 kD and 20 kD respectively. Western blot result showed that the fusion protein of VP1 and its C terminus could react with the positive sera of guinea pig of the same serotype. ELISA results revealed that VP1 and its C terminus of serotype C are type-specific and no cross-reactivities were shown between guinea pig positive sera of FMDV of serotype C with the other three serotypes, and the C terminus showed better type-specificity. [ Conclusion] FMDV specific antigen of serotype C was obtained.

Structural Carpentry in Qing Dynasty-A Framework for the Hierarchically Modularized Chinese Timber Structural Design

This article, by using mathematical expressions, offers a scientific framework for understanding how the grading system of Qing′s structural carpentry determines the design and construction in the grand style timber architecture.The Qing′s grand style timber structure, which is ready for prefabrication and assembly, is extremely hierarchical oriented and significantly standardized. The general procedure in designing a grand style timber structure is to start with the grade that defines the basic module (dou kou); next comes with the number of bracket set (cuan), the number of longitudinal bays and the number of purlins which affect its plan and cross section; thirdly choose a roof type that determines its longitudinal section and the facade as well. A series of formulae are conducted to help depict the layout, cross sectional roof curvature and special longitudinal treatments in 4 sloped and 9 spined roofs respectively.

Preliminary Studies on High-performance Liquid Chro-matography Chemiluminescence Determination of theSaturated Fatty Acids(C_(16) C_(18))in Human Serum

The peroxyoxalate chemiluminescence(CL)detection of fatty acids in human se- rum combined with high-performance liquid chromatography (HPLC)is described.Some fatty acids in serum were extracted with a 1 :1(v/v)mixture of chloroform-n-heptane.2-(4-Hydrazinocarbonyl- phenyl)-4,5-diphenylimidazole (HCPI) was used as a fluorescent labelling reagent of the fatty acids. The labelling reaction was carried out at 30℃ for 1 h at pH 6.5 and the resulting reaction mixture was sudjected to HPLC. The labelled fatty acid C_(17)(P-C_(17))was used as the internal standard. The la- belled fatty acids C_(16) and C_(18) were separated within 18 min on an ODS-8OTM column (150 mm× 6 mm ID,5μm,Tosoh Japan).The calibrlation curves of fatty acids from the spiked control serum were Y_1=-0.003 7 + 0.0028X_1,r=0.994 for FA C_( 16) and Y_2=0.00 1 2 + 0.00098X_2,r=0.999 for FA C_( 18),respectively.The average recoveries of facids from the spiked contrl serum were 107.2%(n=8,RSD=4.3%)for FA C_(16) and 97.35%(n=8, RSD=4.0%)for FA C_(18),respectively.The lower detection limits of fatty acids after reaction were 12μmol per 20μl injection for FA C_(16) and 18 μmol per 20μl injection for FA C_(18),respectively(signal to noise ratio, S/N=2).The HPLC/CL method was applied to the determination of FA C_(16) and FA C_(18) in normal human serum and the results showed that the concentrations of fatty acids in normal human serum were 0.134 ± 0.009 μ mol/ml serum(n=5) for FA C_(16) and 0.052±0.028 μmol/ml serum(n=5)for FA C_(18),respectively.

Morphological and serum hyaluronic acid, laminin and type Ⅳ collagen changes in dimethylnitrosamine-induced hepatic fibrosis of rats

AIM： To study the morphological and serum hyaluronic acid （HA）, laminin （LN）, and type IV collagen changes in hepatic fibrosis of rats induced by dimethylnitrosamine （DMN）.METHODS： The rat model of liver fibrosis was induced by DMN. Serum HA, type IV collagen, and LN were measured by ELISA. The liver/weight index and morphological changes were examined under electron microscope on d 7, 14, 21, and 28 by immunohistochemical alpha smooth muscle actin α-SMA staining as well as Sirius-red and HE staining.RESULTS： The levels of serum HA, type IV collagen and LN significantly increased from d 7 to d 28 （P = 0.043）. The liver/weight index increased on d 7 and decreased on d 28. In the model group, the rat liver stained with lie and Sirius-red showed evident hemorrhage and necrosis in the central vein of hepatic 10 Iobules on d 7. Thin fibrotic septa were formed joining central areas of the liver on d 14. The number of α-SMA positive cells was markedly increased in the model group. Transitional hepatic stellate cells were observed under electron microscope. All rats in the model group showed micronodular fibrosis in the hepatic parenchyma and a network of α-SMA positive cells. Typical myofibroblasts were embedded in the core of a fibrous septum. Compared to the control group, the area-density percentage of collagen fibrosis and pathologic grading were significantly different in the model group （P〈0.05） on different d （7, 14, and 28）. The area-density percentage of collagen fibrosis in hepatic tissue had a positive correlation with the levels of serum HA, LN, and type IV collagen.CONCLUSION： The morphological and serum HA, type IV collagen, and LN are changed in DMN-induced liver fibrosis in rats.

Clinical and epidemiological features of patients with clonorchiasis

AIM:To study the clinical and epidemiological features of patients with clonorchiasis so as to provide scientific evidences for the diagnosis and prevention of clonorchiasis. METHODS:Stools from 282 subjects suspected of having clonorchiasis were examined for helminth eggs with modified Kato's thick smear and sedimentation methods,and their sera were tested for HAV-DNA,HBV-DNA,HCV-RNA,HDV- RNA and HEV-RNA with polymerase chain reaction (PCR). Clinical symptoms of patients with clonorchiasis only were analyzed,and their blood samples were tested for circulating antigen (CAg) with Dot-ELISA,esoinophilic granulocyte count, and alanine aminotransferase (ALT).Meanwhile,they were asked to provide data of occupation,eating habit,hygienic habit and knowledge of donorchiasis.In addition,the ecosystem of the environment in epidemic areas was surveyed. RESULTS:Among the 282 patients,61 (21.43%) were infected with clonorchis sinensis only,97 (34.64%) were co-infected with clonorchis sinensis and other pathogens, 92 (32.86%) were infected with hepatitis virus only and 31 (11.07%) neither with clonorchis sinensis nor hepatitis virus. Among the 61 patients with clonorchiasis only,there were 14 (22.95%) subjects with discomfort over hepatic region or epigasfrium,12 (19.67%) with general malaise or discomfort and inertia in total body,6 (9.84%) with anorexia,indigestion and nausea,4 (6.56%) with fever,dizziness and headache (6.56%),and 25 (40.98%) without any symptoms;sixty one (100%) with CAg (+),98.33% (59160) with eosinophilic granulocytes increased and 65.00% (39/60) with ALT increased.B-mode ultrasonography revealed 61 cases with dilated and thickened walls of intrahepatic bile duct,and blurred patchy echo acoustic image in liver.Twenty-six cases had stones in the bile duct,39 cases had slightly enlarged liver with diffuse coarse spots in liver parenchyma.Twenty cases had enlarged gallbladder with thickened coarse wall and image of floating plagues,9 cases had slightly enlarged spleen.By analysis of epidemiological data,we found that the ecologic environment was favorable for the epidemiology of clonorchiasis.Most patients with clonorchiasis were lack of knowledge about the disease.Their living environment, hygienic habits,eating habits and their occupations were the related factors that caused the prevalence of the disease. CONCLUSION:The clinical symptoms of clonorchiasis are non-specific,and the main evidences for diagnosis of clonorchiasis should be provided by etiologic examination, B-mode ultrasonography and clinical history.The infection of clonorchis sinensis is related to occupations,bad eating habits and lack of knowledge about prevention of the disease.

Mathematical model of cylindrical form tolerance

Tolerance is essential for integration of CAD and CAM. Unfortunately, the meaning of tolerances in the national standard is expressed in graphical and language forms and is not adaptable for expression, processing and data transferring with computers. How to interpret its semantics is becoming a focus of relevant studies. This work based on the mathematical definition of form tolerance in ANSI Y 14.5.1 M-1994, established the mathematical model of form tolerance for cylindrical feature. First, each tolerance in the national standard was established by vector equation. Then on the foundation of toler-ance's mathematical definition theory, each tolerance zone's mathematical model was established by inequality based on degrees of feature. At last the variance area of each tolerance zone is derived. This model can interpret the semantics of form tolerance exactly and completely.

Changing patterns of hepatitis A prevalence within the Saudi population over the last 18 years

AIM： To determine the seroprevalence of Hepatitis A （HAV） amongst Saudi children and compare it with previously reported prevalence data from the same population. METHODS： A total of 1357 students were randomly selected between the ages of 16 and 18 years （689 males and 668 females） from three different regions of Saudi Arabia （Madinah, AI-Qaseem, and Aseer） and tested for anti-HAV-IgG.RESULTS： The overall prevalence of anti-HAV-IgG among the study population was 18.6%. There was no difference between males and females but there was a significant difference in the seroprevalence （P = 0.0001） between the three different regions, with Madinah region showing the highest prevalence （27.4%）. When classified according to socioeconomic status, lower class students had a prevalence of 36.6%, lower middle class 16.6%, upper middle class 9.6%, and upper class 5.9% （P = 0.0001）. Comparing the current study results with those of previous studies in 1989 and 1997 involving the same population, there was a marked reduction in the overall prevalence of HAV from 52% in 1989, to 25% in 1997, to 18.6% in 2008 （P 〈 0.0001）.CONCLUSION： Over the last 18 years, there has been a marked decline in the prevalence of HAV in Saudi children and adolescents. The current low prevalence rates call for strict adherence to vaccination policies in high-risk patients and raises the question of a universal HAV vaccination program.

HBV cccDNA in patients' sera as an indicator for HBV reactivation and an early signal of liver damage

AIM:To evaluate the covalently closed circle DNA (cccDNA) level of hepatitis B virus (HBV) in patients' liver and sera. METHODS:HBV DNA was isolated from patients' liver biopsies and sera.A sensitive real-time PCR method,which is capable of differentiation of HBV viral genomic DNA and cccDNA,was used to quantify the total HBV cccDNA.The total HBV viral DNA was quantitated by real-time PCR using a HBV diagnostic kit (PG Biotech,LTD,Shenzhen,China) described previously. RESULTS:For the first time,we measured the level of HBV DNA and cccDNA isolated from ten HBV patients' liver biopsies and sera.In the liver biopsies,cccDNA was detected from all the biopsy samples.The copy number of cccDNA ranged from from 0.03 to 173.1 per cell,the copy number of total HBV DNA ranged from 0.08 to 3 717 per cell.The ratio of total HBV DNA to cccDNA ranged from 1 to 3 406.In the sera, cccDNA was only detected from six samples whereas HBV viral DNA was detected from all ten samples.The ratio of cccDNA to total HBV DNA ranged from 0 to 1.77%.To further investigate the reason why cccDNA could only be detected in some patients' sera,we performed longitudinal studies.The cccDNA was detected from the patients' sera with HBV reactivation but not from the patients' sera without HBV reactivation.The level of cccDNA in the sera was correlated with ALT and viral load in the HBV reactivation patients. CONCLUSION:HBV cccDNA is actively transcribed and replicated in some patients' hepatoo/tes,which is reflected by a high ratio of HBV total DNA vs cccDNA.Detection of cccDNA in the liver biopsy will provide an end-point for the anti-HBV therapy.The occurrence of cccDNA in the sera is an early signal of liver damage,which may be another important clinical parameter.

Application of response surface methodology to the chemical cleaning process of ultrafiltration membrane

A numerical model was established to predict and optimise the chemical cleaning process of Polyvinylidene Fluo- ride （PVDF） Ultrafiltration （UF） membranes with the results from the experiment that applied the Response Sur- face Method （RSM） and Central Composite Design （CCD）. The factors considered in the experimental design were sodium hydroxide （NaOH） concentration, sodium bypochlorite concentration （NaCIO）, citric acid concentration and cleaning duration, The interactions between the factors were investigated with the numerical model. Humic acid （20 mg· L-1） was used as the model foulant, and chemical enhanced backflush （CEB） was employed to sim- ulate the chemical cleaning process. The concentrations of sodium hydroxide, sodium hypochlorite, citric acid and cleaning duration tested during the experiments were in the range of 0.1%-0.3% 100-300 mg· L-1 1%-3% and 0.5-1.5 h, respectively. Among the variables, the sodium hypochlorite concentration and the cleaning dura- tion showed a positive relationship involving the increased efficiency of the chemical cleaning. The chemical cleaning efficiency was hardly improved with increasing concentrations of sodium hydroxide. However, the data was sharply decreased when at a low level of sodium hydroxide concentration. In total, 54 sets of cleaning schemes with 80% to 100K cleaning efficiency were observed with the R＆M model after calibration.

Autoimmune liver serology:Current diagnostic and clinical challenges

Liver-related autoantibodies are crucial for the correct diagnosis and classification of autoimmune liver diseas-es(AiLD),namely autoimmune hepatitis types 1 and 2(AIH-1 and 2),primary biliary cirrhosis(PBC),and the sclerosing cholangitis variants in adults and children.AIH-1 is specified by anti-nuclear antibody(ANA) and smooth muscle antibody(SMA).AIH-2 is specified by antibody to liver kidney microsomal antigen type-1(anti-LKM1) and anti-liver cytosol type 1(anti-LC1).SMA,ANA and anti-LKM antibodies can be present in de-novo AIH following liver transplantation.PBC is specified by antimitochondrial antibodies(AMA) react-ing with enzymes of the 2-oxo-acid dehydrogenase complexes(chiefly pyruvate dehydrogenase complex E2 subunit) and disease-specific ANA mainly react-ing with nuclear pore gp210 and nuclear body sp100.Sclerosing cholangitis presents as at least two variants,first the classical primary sclerosing cholangitis(PSC) mostly affecting adult men wherein the only(and non-specific) reactivity is an atypical perinuclear antineutro-phil cytoplasmic antibody(p-ANCA),also termed peri-nuclear anti-neutrophil nuclear antibodies(p-ANNA) and second the childhood disease called autoimmune sclerosing cholangitis(ASC) with serological features resembling those of type 1 AIH.Liver diagnostic serol-ogy is a fast-expanding area of investigation as new purified and recombinant autoantigens,and automatedtechnologies such as ELISAs and bead assays,become available to complement(or even compete with) tradi-tional immunofluorescence procedures.We survey for the first time global trends in quality assurance impact-ing as it does on(1) manufacturers/purveyors of kits and reagents,(2) diagnostic service laboratories that fulfill clinicians' requirements,and(3) the end-user,the physician providing patient care,who must properly interpret test results in the overall clinical context.

Depression and chronic heart failure in the elderly： an intriguing relationship

Chronic heart failure and depressive disorders have a high prevalence and incidence in the elderly. Several studies have shown how depression tends to exacerbate coexisting chronic heart failure and its clinical outcomes and vice versa, especially in the elderly. The negative synergism between chronic heart failure and depression in the elderly may be approached only taking into account the multifaceted pathophysiological characteristics underlying both these conditions, such as behavioural factors, neurohormonal activation, inflammatory mediators, hypercoagulability and vascular damage. Nevertheless, the pathophysiological link between these two conditions is not well established yet. Despite the high prevalence of depression in chronic heart failure elderly patients and its negative prognostic value, it is often unrecognized especially because of shared symptoms. So the screening of mood disorders, using reliable questionnaires, is recommended in elderly patients with chronic heart failure, even if cannot substitute a diagnostic interview by mental health professionals. In this setting, treatment of depression requires a multidisciplinary approach including： psychotherapy, antidepressants, exercise training and electroconvulsive therapy. Pharmacological therapy with selective serotonin reuptake inhibitors, despite conflicting results, improves quality of life but does not guarantee better outcomes. Exercise training is effective in improving quality of life and prognosis but at the same time cardiac rehabilitation services are vastly underutilized.

Transformation of hepatitis B serologic markers in babies born to hepatitis B surface antigen positive mothers

AIM:To better understand the clinical significance of hepatitis B seroiogic markers in babies born to hepatitis B surface antigen (HBsAg) positive mothers, the incidence of maternal seroiogic markers of hepatitis B via placenta and its transformation in these babies were investigated. METHODS: Mothers with positive HBsAg were selected in the third trimester of pregnancy. Their babies received immunoprophylaxis with hepatitis B immunoglobulin and hepatitis B vaccine after birth, and were consecutively followed up for hepatitis B seroiogic markers and HBV DNA at birth, mo 1, 4, 7, 12, and 24. RESULTS: Forty-two babies entered the study, including 16 born to hepatitis B e antigen (HBeAg)-positive HBsAg carrier mothers and 26 to HBeAg-negative HBsAg carrier mothers. Apart from four babies born to HBeAg-positive carrier mothers and demonstrated persistent positive HBeAg eventually became HBV carriers, all other babies developed anti-HBs before 12 mo of age. Among the other 12 babies born to HBeAg-positive carrier mothers, HBeAg was detected in 7 at birth, in 4 at mo 1, and in none of them thereafter. No antibody response to the transplacental HBeAg was detected. Among the babies born to HBeAg-negative carrier mothers, anti-HBe was detected 100% at birth and mo 1, in 88.5% at mo 4, in 46.2% at mo 7, in 4.2% at mo 12 and none in mo 24. Among all the immunoprophylaxis-protected babies born to either HBeAg-positive or HBeAg-negative carrier mothers, anti-HBc was detected in 100% at birth, mo 1 and mo 4, in 78.9% at mo 7, in 36.1% at mo 12 and in none at mo 24. CONCLUSION: HBeAg can pass through human placenta from mother to fetus and become undetectable before 4 mo of age, but no antibodies response to the transplacental HBeAg can be detected till mo 24 in the immunoprophylaxis-protected babies. The sole existence of anti-HBe before 1 year of age or anti-HBc before 2 years of age in babies born to HBsAg carrier mothers may simply represent the transplacental maternal antibodies, instead of indicators of HBV infection status.

Cytomegalovirus frequency in neonatal intrahepatic cholestasis determined by serology, histology, immunohistochemistry and PCR

AIM: To determine cytomegalovirus (CMV) frequency in neonatal intrahepatic cholestasis by serology, histological revision (searching for cytomegalic cells), immunohistochemistry, and polymerase chain reaction (PCR), and to verify the relationships among these methods.METHODS: The study comprised 101 non-consecutive infants submitted for hepatic biopsy between March 1982 and December 2005. Serological results were obtained from the patient's f iles and the other methods were performed on paraffin-embedded liver samples from hepatic biopsies. The following statistical measures were calculated: frequency, sensibility, specif ic positive predictive value, negative predictive value, and accuracy.RESULTS: The frequencies of positive results were as follows: serology, 7/64 (11%); histological revision, 0/84; immunohistochemistry, 1/44 (2%), and PCR, 6/77 (8%). Only one patient had positive immunohistochemical fi ndings and a positive PCR. The following statistical measures were calculated between PCR and serology: sensitivity, 33.3%; specificity, 88.89%; positive predictive value, 28.57%; negative predictive value, 90.91%; and accuracy, 82.35%. CONCLUSION: The frequency of positive CMV varied among the tests. Serology presented the highest positive frequency. When compared to PCR, the sensitivity and positive predictive value of serology were low.

New serological biomarkers of inflammatory bowel disease

Serological biomarkers in inflammatory bowel disease (IBD) are a rapidly expanding list of non-invasive tests for objective assessments of disease activity, early diagnosis, prognosis evaluation and surveillance. This review summarizes both old and new biomarkers in IBD, but focuses on the development and character-ization of new serological biomarkers (identifi ed since 2007). These include fi ve new anti-glycan antibodies, anti-chitobioside IgA (ACCA), anti-laminaribioside IgG (ALCA), anti-manobioside IgG (AMCA), and antibod-ies against chemically synthesized (∑) two major oligomannose epitopes, Man α-1,3 Man α-1,2 Man (∑Man3) and Man α-1,3 Man α-1,2 Man α-1,2 Man (∑Man4). These new biomarkers serve as valuable complementary tools to existing biomarkers not only in differentiating Crohn's disease (CD), ulcerative colitis (UC), normal and other non-IBD gut diseases, but also in predicting disease involvement (ileum vs colon), IBD risk (as subclinical biomarkers), and disease course (risk of complication and surgery). Interestingly, the prevalence of the antiglycan antibodies, including anti-Saccharomyces cerevisiae antibodies (ASCA), ALCA and AMCA, was found to be associated with single nucleotide polymorphisms (SNPs) of IBD susceptible genes such as NOD2/CARD15, NOD1/CARD4, toll-likereceptors (TLR) 2 and 4, and β-defensin-1. Further-more, a gene dosage effect was observed: anti-glycan positivity became more frequent as the number of NOD2/CARD15 SNPS increased. Other new serum/ plasma IBD biomarkers reviewed include ubiquitination factor E4A (UBE4A), CXCL16 (a chemokine), resistin, and apolipoprotein A-IV. This review also discusses the most recent studies in IBD biomarker discovery by the application of new technologies such as proteomics, fourier transform near-infrared spectroscopy, and mul-tiplex enzyme-linked immunosorbent assay (ELISA)'s (with an emphasis on cytokine/chemokine profiling). Finally, the prospects of developing more clinically use-ful novel diagnostic algorithms by incorporating new technologies in serological biomarker profiling and integrating multiple biomarkers with bioinformatics analysis/modeling are also discussed.
