Near infrared chemical imaging (NIR-CI) is an emerging technology for rapidly analyzing the critical quality attribute of Chinese materia medica (CMM). It integrates NIR spectroscopy with chemical imaging. In this paper, it provided a systematic introduction to NIR-CI, such as the core part of instrument, the reliability, transformation, analysis and application of high-dimensional data acquisition. In addition, current studies of NIR-CI application in pharmaceutical field were analyzed. Finally, future opportunities and challenges of NIR -CI applications in the quality control of CMM preparation were prospected.

Objective To investigate the distribution pattern and antimicrobial resistance of the clinical isolates of pathogen.Methods The identification and dug susceptibility tests of the isolates from 2013 to 2015 were performed by using VITEK2-compact system.The susceptibilities of isolates to antimicrobial agents were analyzed with WHONET 5.6 software.Results A Total of 2 991(90.4%) gram-negative bacteria and 317(9.6%) gram-positive bacteria were isolated.Among all of the isolates,the top three pathogens were Klebsiella pneumonia,followed by Pseudomonas aeruginosa and Acinetobacter baumannii.The detection rates of extended-spectrum beta-lactamase(ESBLs)-producing Escherichia coli were 40.4%,48.2% and 38.3% respectively in the three consecutive years,while the detection rates of the ESBLs-producing Klebsiella pneumonia were 16.9%,8.4% and 11.6% respectively.No Escherichia coli resistant to impenem were detected.The resistant rate to impenem of Klebsiella pneumonia was 1.6%.The detection rates of methicillin resistant Staphylococcus aureus(MRSA) and methicillin resistant coagulase-negative staphylococci(MRCNS) in the three years were 53.8%,54.3%,42.9% and 84.5%,82.7%,85.9% respectively.No Staphylococci isolates resistant to linezolid and tigecycline were found.Enterococcus isolates were sensitive to gentamicine,linezolid,tigecycline and vancomycin.Conclusion Carbapenems could remain the best antimicrobials against Enterobacteriaccae.Lnezolid and tigecycline could be effective antimicrobials against Staphylococci isolates.The detection rates of Klebsiella pneumonia and Acinetobacter baumannii increased year by year.The monitoring of drug resistance should be strengthened to control the emergence and spread of multidrug resistant pathogen.

Objective To investigate the impact of fatty liver on antiviral effect in the patients with chronic hepatitis B (CHB) .Methods A total of 204 patients with hepatitis Be antigen (HBeAg ) positive CHB in the outpatient department of our hospital from January 2011 to April 2014 were selected as the research subjects and divided into the two groups according to wheth‐er complicating fatty liver :the simple CHB group(control group ,122 cases) and CHB complicating nonalcoholic fatty liver disease (NAFID) group(observation group ,82 cases) .The two groups all received the 24‐week antiviral therapy of adefovir (10 mg/d) . The differences in the normalization rate of ALT/AST (biochemical response) ,HBeAg negative conversion rate (serological re‐sponse) and HBV DNA negative conversion rate(virological response) were compared between the two groups .Then the cases ob‐taining the virological response after treatment in the two groups were compared again .Among the cases obtaining virological re‐sponse,thedifferencesinthenormalizationrateofALT/AST(biochemicalresponse)andHBeAgnegativeconversionrate(serologi‐cal response) were compared between the simple CHB group and CHB complicating NAFID group .Results The normalization rate of ALT/AST after 24‐week treatment in the CHB complicating NAFID group was 58 .5% ,which was significantly lower than 72 .1% in the simple CHB group ,the difference was statistically significant ;the negative conversion rate of HBV DNA and HBeAg after 24‐week treatment in the simple CHB group was 67 .2% and 52 .5% ,which were significantly higher than 51 .2% and 37 .8%respectively ,the differences were statistically significant ;among the cases obtaining the virological response ,the normalization rate of ALT/AST in the simple CHB group was 96 .3% ,which was significantly higher than 66 .7% in the CHB complicating NAFID group ,the difference was statistically significant .But among the cases obtaining the virological response ,the negative conversion rate of HBeAg was 78 .0% in the simple CHB group and 73 .8% in the CHB complicating NAFID group ,the simple CHB group was slightly higher than the CHB complicating NAFID group without statistical difference .Conclusion NAFLD has impact on the antiviral effect of adefovir treatment in CHB patients with positive HBeAg ,whereas complicating NAFLD is an important reason for reaching the virological response and serological response ,but without reaching the biochemical response in the antiviral treatment of CHB complicating NAFID .

This study was aimed to establish an HPLC method for the determination of liquiritin, isoliquiritin, liquiritigenin and glycyrrhizic acid in roots and knotty rhizome of Glycyrrhiza uralensis. The analysis was performed on a Diamonsil C18 column (250 mm í 4.6 mm, 5 μm) by using a gradient elution with mobile phase of water, phosphoric acid, acetonitrile at the flow rate of 1.0 mL·min-1. The detection wavelength was 276 nm (0~18 min), 360 nm (18~24 min), 276 nm(24~30 min), and 250 nm (30~65 min). The column temperature was set at 30℃. The results showed that the linear range of iquiritin, isoliquiritin, liquiritigenin, glycyrrhizic acid was 0 . 108 5~1 . 085、0 . 016 8~0 . 168、0 . 0049 4~0 . 049 4、0 . 407~4 . 07μg , respectively . The average recoveries of four constituents were 96.61%~100.89%, with RSD ≤ 0.81%. The contents of four constituents in roots of five batches were 0.513%, 0.072 9%, 0.048 4%, and 1.945%, respectively. Contents of four constituents in knotty rhizome from two batches were 0.456%, 0.063 6%, 0.036 2%, and 1.630%, respectively. It was concluded that there was good linear relationship between the response and concentration. Contents of four constituents in knotty rhizome were basically the same as those in the roots. The knotty rhizome can be used as raw material for the extraction of active components.

This study was aimed to optimize the near infrared (NIR) variable selection method based on multivariate detection limit (MDL). Using Qing-Kai-Ling (QKL) injection as object, three variable selection methods (interval par-tial least-squares, iPLS; backward interval partial least squares, BiPLS; moving window interval partial least squares, mwPLS) were used to establish the PLS models of baicalin in QKL injection, respectively. The prediction ability of different variable selection method was compared. MDL of all models were calculated in contrast to the MDL value of full spectra PLS model, to select optimal variable selection method. The results showed that different variable selec-tion methods had different prediction ability. Among them, iPLS had the best performance which determination coef-ficient of prediction (Rpre2) and the root mean square errors of prediction (SEP) were 0.996 5 and 602.3 μg·mL-1, re-spectively. All MDLs of different variable selection methods were reduced compared with the full spectra PLS model. The value of iPLS was the lowest comes to be 1.19 μg·mL-1. The results above indicated that the best variable se-lection method for baicalin in QKL injection was iPLS. MDL theory took the error of calibration and validation set and the leverage of external sample into account, which can comprehensively evaluate model detection performance compared to the classic chemical indicator parameters. This method was particularly suitable for the variable selec-tion method optimization of NIR quantitative model of low concentration sample such as Chinese herbal medicine.
