To develop nondestructive acidity prediction for intact Fuji apples, the potential of Fourier transform near infrared (FT-NIR) method with fiber optics in interactance mode was investigated. Interactance in the 800 nm to 2619 nm region was measured for intact apples, harvested from early to late maturity stages. Spectral data were analyzed by two multivariate calibration techniques including partial least squares (PLS) and principal component regression (PCR) methods. A total of 120 Fuji apples were tested and 80 of them were used to form a calibration data set. The influences of different data preprocessing and spectra treatments were also quantified. Calibration models based on smoothing spectra were slightly worse than that based on derivative spectra, and the best result was obtained when the segment length was 5 nm and the gap size was 10 points. Depending on data preprocessing and PLS method, the best prediction model yielded correlation coefficient of determination (r2) of 0.759, low root mean square error of prediction (RMSEP) of 0.0677, low root mean square error of calibration (RMSEC) of 0.0562. The results indicated the feasibility of FT-NIR spectral analysis for predicting apple valid acidity in a nondestructive way.

OBJECTIVETo evaluate the incidence of Ketoconazole associated hepatotoxicity and related factor.
METHODSLiterature retrieval was conducted by using multi-databases for meta-analysis on Ketoconazole associated hepatotoxicity. The data were collected with a standardized form. Overall estimation of incidence of hepatotoxicity for specific study type was calculated by using a DerSimonian-Laird random-effects model owing to the substantial differences among the studies.
RESULTSTotally 204 eligible studies were included in the analysis. The incidence of Ketoconazole associated hepatotoxicity was 3.6%-4.2%. The dosage and duration specific subgroup analyses did not show any significant difference among groups, while the age specific subgroup analysis showed the incidence in children and people aged >60 years was 1.4% (95% CI: 0.5%-4.2%) and 3.2% (95% CI: 1.1%-8.7%) respectively. Additionally, the incidence of the hepatotoxicity was higher in people who had oral administration of ketoconazole beyond the provisions of the usage instructions, and the incidence was 5.7% (95% CI: 4.5%-7.2%).
CONCLUSIONKetoconazole associated hepatotoxicity was common. Off-label use might increase the risk of liver damage. Well-designed large sample studies are needed to identify the risk factors in future.

This study was aimed to explore the correlation of hemogram changes during pregnancy of healthy women with postpartum blood transfusion. The outpatient and inpatient information of expectant lying-in women in our hospitals was collected, the route blood test, lever and kidney function and blood coagulation function tests were performed from the 4th to the 10th month of pregnancy. The pregnant women without underlying diseases and non-elderly pregnant women with single fetus were selected as the subjects of study. They were divided into postpartum blood transfusion group and non-blood transfusion group. The white blood cell (WBC) count, hemoglobin (Hb) level, platelet (Plt) count, plateletocrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW) were compared in 2 groups. The results showed that 68 cases out of 450 expectant lying-in women received blood transfusion, among them 30 cases with complete data of puerperal transfusion were taken as blood transfusion group, the 28 cases of non transfusion puerperal as control group. There was no significant difference of hemogram changes between the two groups. However, there was a slight decline in Plt count and Hb level of late pregnant women. What is more, there was no correlation between Plt count change and the PCT, MPV and PDW. It is concluded that the changes of hemogram during pregnancy has no correlation with postpartum hemorrhage and blood transfusion in healthy pregnant women, the Plt count and Hb level of pregnant women slightly decline. Nevertheless, PCT, MPV and PDW are within the normal range.

BACKGROUNDTo investigate the mutation of HBV polymerase gene in chronic hepatitis B patients treated with lamivudine.
METHODSThe restriction-fragment-length-polymorphism (RFLP) assay for HBV DNA sequence determination at the codon 528 and 552 in the HBV polymerase gene associated with lamivudine resistance in vitro. HBV DNA samples extracted from sera of 240 patients were subjected to PCR amplification with primer pairs F2/R2 (552), F3/R2 (528). Each PCR product was digested with Nde I or Nla III.
RESULTSSerum HBV DNA mutation was found in 51/240 patients (38/51M552V, 26/38L528M, 13/51M552I) after therapy for 52 weeks. DNA sequence analysis was performed on samples of 3 patients, and the results were consistent with those of RFLP assay.
CONCLUSIONThe RFLP assay was able to detect the mutation of HBV DNA at codon 552 and 528 which are the principal site of HBV DNA resistant to lamivudine. The specific PCR method for HBV DNA mutation is rapid, simple and specific.

OBJECTIVETo investigate the relationship between the resuscitation promoting role of resuscitation promoting factor and the initial bacteria amount of dormant Mycobacterium tuberculosis.
METHODSMycobacterium tuberculosis (dormant bacteria) was cultured for 100 days, then diluted into 1 mg/ml concentration with 7H9, and further diluted into 0.5, 0.25, 0.125, 0.0625, and 0.03125 mg/ml. Twelve new tubes added with 5 ml 7H9 and divided into two groups: the first group was added with the resuscitation-promoting factor protein, and the second group as control was added with 7H9. In each group the above diluted solutions were added. The tubes were located at 37 degrees C for culture. Optical density (OD) was detected on day 15, 25, 30, and 35. From each tube 1 microl culture solution was plated on 7H11 medium for colony counting.
RESULTSOD detection showed that bacteria proliferation in each group had positive linear correlation (P < 0.05, P < 0.01), indicating that the resuscitation-promoting factor played a similiar role in solutions with different dilution concentrations. 7H11 results and the OD results show that these two detection methods in each group had linear correlation (P < 0.05, P < 0.01), indicating that these two methods showed consistent test results.
CONCLUSIONThe resuscitation-promoting factor has no effect on the resuscitation of dormant Mycobacterium tuberculosis and its initial bacteria amount.
