To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Objective To systematically evaluate the association between IL-6 gene rs1800796 polymorphism and febrile seizures(FS)susceptibility.Methods The related literatures on IL-6 gene rs1800796 polymorphism and febrile seizures(FS)susceptibility were retrieved from PubMed,Web of Science Embase,Cochrane Library,CNKI,WanFang,VIP and CBM Databases by computer.OR and its 95%CI were taken as the pooled effects.The RevMan 5.2 software was adopted to conduct the statistical analysis.The publication bias analysis was performed by using the STATA12.0 software.Results Seven independent case-control studies were included according to the inclusion and exclusion standard,involving 516 accumulated cases and 528 controls.The results showed that IL-6 gene rs1800796 polymorphism had a significant association with FS susceptibility in Chinese population(GG+CG vs.CC:OR=2.22,P=0.05;G vs.C:OR=2.44,P<0.01;GG vs.CC:OR=3.69,P=0.03;GG vs.CG+CC:OR=3.43,P<0.01).The subgroup analysis was conducted according to possible important confounding factors,and the results showed that this gene polymorphism had a significant association with FS susceptibility in Chinese population(GG+CG vs.CC:OR=3.32,P<0.01;G vs.C:OR=3.23,P<0.01;GG vs.CC:OR=7.27,P<0.01;GG vs.CG+CC:OR=5.17,P<0.01:CG vs.CC:OR=2.56,P=0.02).But in other populations,except recessive model(GG vs.CG+CC:OR=2.40,P<0.01),all other genetic models did not display obvious correlation.The subgroup analysis was conducted by FS diagnostic standard,and the results showed that this gene polymorphism had a significant correlation with infantile FS onset in diagnosing FS by the Chinese standard(GG+CG vs.CC:OR=4.57,P<0.01;G vs.C:OR=4.36,P<0.01;GG vs.CC:OR=12.75,P<0.01;GG vs.CG+CC:OR=8.60,P<0.01:CG vs.CC:OR=3.40,P<0.01).Conclusion IL-6 gene rs1800796 polymorphism may be associated with infantile FS susceptibility and allele G may be a risk factor for FS onset.

Objective:To improve the safety,rationality and efficacy of medication for ovarian cancer patients complicated with cirrhosis by the participation of clinical pharmacists in the therapy. Methods:Clinical pharmacists participated in the therapy for an ovarian cancer patient with cirrhosis,and provided a rational and individualized therapeutic regimen through the drug experience of clinical pharmacists as well as the relevant medical guides and literatures. Results:The therapeutic efficacy was increased by the participation of clinical pharmacists in the therapy,the potential risk of the chemotherapy was avoided and the security of medication was assured. Conclusion:The participation of clinical pharmacists in therapeutic practice can improve the normalization of pharmacotherapy for ovarian cancer patients with cirrhosis,which also can provide ideas and methods for treating the similar patients.

Astragalus membranaceus var. mongholicus and Hedysarum polybotrys belong to different genera, but have similar drug efficacy in traditional Chinese medicine theory, and H. polybotrys was used as the legal A. membranaceus var. mongholicus previously. In this study, similarities and differences between them were analyzed via their ITS/ITS2 fragments information. The ITS (internal transcribed spacer) regions were amplified using polymerase chain reaction and then sequenced in two-way. The alignment lengths of ITS regions were 616 bp, in which 508 loci were consistent, and 103 loci were different, accounting for 82.47% and 16.72% of the total ITS nucleotides in length, respectively. As genotype determines phenotype, 1HNMR-based metabolomic approach was further used to reveal the chemical similarities and differences between them. Thirty-four metabolites were identified in the 1H NMR spectra, and twenty-seven metabolites were the common components. Amino acids, carbohydrates and other primary metabolites were similar, while a large difference existed in the flavonoids and astragalosides. This study suggests that A. membranaceus var. mongholicus and H. polybotrys show similarities and differences from molecular and chemical perspectives, which has laid a foundation for elucidating the effective material basis of drug with similar efficacy and resources utilization.

AIM:To explore relationship between the normal strehl ratio ( SR ) values of total aberrations/SR values of total higher-order aberrations and modulation transfer function ( MTF ) at total corneal at different pupil diameters in normal population.
METHODS: To exam the SR values of total aberrations and SR values of total higher-order aberrations of total corneals in 200 people ( 400 eyes ) using SIRIUS 3D topography system and analysis the corresponding root-mean-square ( RMS) .
RESULTS: The subjects with different pupil diameters (3. 0, 5. 0, 6. 0, 7. 0mm)'s exam results of total corneal were as following:SR value of total aberrations 100’(0. 45±0. 12), (0. 25±0. 06), (0. 17±0. 05), (0. 13±0. 04); SR value of total higher order ab cerrations 100’(0. 69±0. 14), (0. 34±0. 07), (0. 24±0. 05), (0. 16±0. 04);SR value of total aberrations 200’(0. 45±0. 12), (0. 24±0. 06), (0. 20±0. 04), (0. 16±0. 03); SR value of total higher order aberrations 200’(0.70±0. 13), (0. 35±0. 07), (0. 27±0. 06), (0. 20±0.04 ) . The SR values of each group decreases with the increases of pupil diameters. The SR values of total aberrations and SR values of total higher - order aberrations at total corneals are negatively correlated with corresponding RMS value. When the pupil diameter is small, the SR value of total aberrations is more related to higher frequency region of MTF. When the pupil diameter is big, the SR value of total aberrations is more related to lower frequency region of MTF.
CONCLUSION: The visual performance of normal people can be well reflected by SR values of total aberrations and SR values of total higher - order aberrations at total corneal.

Nowadays, nanotechnologies have shown wide application foreground in the biomedical field of medicine laboratory tests, drug delivery, gene therapy and bioremediation. However, in recent years, nanomaterials have been labeled poisonous, because of the disputes and misunderstandings of mainstream views on their safety. Besides, for the barriers of technical issues in preparation like: (1) low efficacy (poor PK & PD and low drug loading), (2) high cost (irreproducibility and difficulty in scale up), little of that research has been successfully translated into commercial products. Currently, along with the new theory of "physical damage is the origin of nanotoxicity", biodegradability and biocompatibility of nanomaterials are listed as the basic principle of safe application of nanomaterials. Combining scientific design based on molecular level with precision control of process engineering will provide a new strategy to overcome the core technical challenges. New turning point of translational medicine in nanotechnology may emerge.
