To explore a new method to identify Moutan Cortex to guarantee its safe use, internal transcribed spacer 2 (ITS2) sequence was used to identify Moutan Cortex and its adulterants. DNA was extracted and target fragments were amplified. Sequences were analyzed and assembled by CodonCode Aligner V3.7.1. Genetic distances were computed and phylogenetic tree was constructed based on kimura 2-parameter (K2P) model by MEGA 5.0. The length of the 20 ITS2 sequences of Moutan Cortex from nine different places is 227 bp, and no variation site was detected. The maximum inter-specificK2P distance of Moutan Cortex is 0, the minimum intra-specific K2P distance is 0.041, the average intra-specific K2P distance is 0.222. According to NJ analysis, Moutan Cortex from different places can get together as one branch with bootstrap support values 99%, which indicates Moutan Cortex can be easily distinguished from its adulterants. Using ITS2 sequence can accurately identify Moutan Cortex and its adulterants, it is an effective supplementary to traditional identification methods.

We used metabolomics to investigate the ability of a traditional Mongolian medicine called modified Tabusen-2 (MT-2) to improve kidney yang deficiency (KYD) in rats. All animal experiments were conducted under the guidance and standards of the Medical Ethics Committee of Inner Mongolia Medical University. SD rats were divided into 6 groups of six rats: a normal group, a model group, Jinkuishenqi pill administration group (1.26 g·kg-1), and MT-2 administration in high-, medium- and low-dose groups (1.512, 0.756, and 0.378 g·kg-1). KYD was established by intramuscular injection of hydrocortisone (HC) and biochemical indicators and clinical characterization was used to confirm that KYD was established. All groups received intragastrically administered drug (Jinkuishenqi pill or MT-2) or saline. Serum from each group was collected after 8 weeks and analyzed by UPLC-Q-exactive-MS to measure various biochemical indicators. The biomarkers affected by MT-2 were identified and the metabolic pathways of KYD regulated by MT-2 were analyzed by metabolomic analysis. The results show that MT-2 can decrease serum creatinine (Cr) in KYD rats and significantly increase (

OBJECTIVETo analyze the prognostic factors of colorectal cancer patients with synchronous liver metastasis treated by simultaneous colorectal and liver resection.
METHODSThe clinical and follow-up data of 44 colorectal cancer patients with synchronous liver metastases who underwent simultaneous colorectal and liver resection from Jan. 1993 to Jan. 2003 were analyzed retrospectively. Survival rate was estimated by Kaplan-Meier method, and was compared using log-rank test. Prognostic factors were analyzed by multivariate Cox proportional hazards model.
RESULTSThe overall 1-, 3- and 5-year survival rates were 86.3%, 40.9% and 25.0%, respectively. The lymph node metastasis and vascular invasion by cancer cells from the primary tumour were found to affect prognosis significantly, while gender, age, tumor location, histopathological types, the number and distribution of liver metastases were not. Multivariate analysis revealed that the lymph node metastasis was the only independent prognostic factor.
CONCLUSIONSimultaneous liver and colorectal resection can be performed and may achieve good outcome in colorectal cancer patients with synchronous liver metastases, especially in those without lymph node metastasis.

This study was aimed to explore whether the graft-versus-host disease (GVHD) could be alleviated by intra-bone marrow (IBM) infusion of allogeneic hematopoietic stem cells. Female C57BL/6 mice as recipients received total body irradiation (TBI) 4 Gy on day 0, followed by injection of peripheral hematopoietic stem cells (1 x 10(7)) from mobilized male BALB/c with granulocyte-colony stimulating factor (rhG-CSF), and cyclophosphamide (200 mg/kg) was injected intraperitoneally two days later. The results showed that the incidence and severity of GVHD were more low and alleviative in group IBM-PBSCT than that in group TV-PBSCT (p < 0.05). Y chromosome of donor mice could be detected in the bone marrow of recipient mice. It is concluded that the method of intra-bone marrow infusion is superior to injection via the tail vein in the engraftment of hematopoietic stem cells in terms of stem cell homing while the frequency and severity of GVHD in allogeneic mice decrease.

Novel solid lipid nanoparticle (SLN) system is prepared with Compritol ATO 888 and tricaprylic glyceride. DSC, XRD, SAXS and NMR are employed to study the novel carrier property and microstructure. When the peak melting point decreased from 70.8 degrees C to 61.4 degrees C, the enthalpy sharply decreased. It could be concluded that the regular crystal lattices in the novel carriers are broken out for the oil joined in them. Melting behavior is occurred at -17.7 degrees C while novel SLN is composed of oil and solid lipid mixture from the DSC measurement. Most alpha phase and least beta' phase are in the nano carrier system whether drug loading or not from the XRD investigation. There is only 0.1 nm change of long space among the novel SLN made of mixture and the lipid matrix and traditional SLN; therefore, it is impossible of the oil molecular insert into the solid glyceride structure. Since the different melting behavior (DSC measurements) and molecular move state (NMR investigations), two lipid matrix are still in two state of liquid and solid lipid in the novel SLN carrier. Presume the microstructure of the novel SLN prepared by our experiment would be that liquid oil has formed superfine nano accommodation encapsulated with solid lipid, but the whole particle is still in nano size range.

To explore the differences between the qualitative similarity and the quantitative similarity of chromatographic fingerprints of traditional Chinese medicines, the quantitative similarity calculated by vector shadow C%, apparent quantitative similarity R%, quantitative similarity P%, etc. were firstly proposed to disclose the quantitative information characteristics of traditional Chinese medicines fingerprints. The HPLC fingerprints of both the standard Fructus gardeniae and the ten batches of Fructus gardeniae produced in different places were evaluated by the new parameters to obtain good results. The contrasted fingerprint contained 35 peaks while geniposide was selected as the reference peak. The HPLC fingerprint had good precision and reproducibility with the RSD of the relative retention time less than 1.5% and the RSD of the relative peak area within 5%. The qualitative similarity and quantitative similarity between each crude drug and the contrasted fingerprint were quantitatively calculated, the values of C%, P%, etc., were applied in the quality control practice, which had less errors. What is more, this method could be used for the overall quality control of Fructus gardeniae and especially suits for qualitative and quantitative evaluations of the chromatographic fingerprints both in chemical constituent distribution and in contents. The quantitative parameters such as C% and P% can be used to objectively, authentically and thoroughly display the content information characteristics. When they combined with the qualitative similarity, it will be the good method to evaluate the chromatographic fingerprints of traditional Chinese medicines.
