Objective To observe clinical effect of self-made xiaozhongsanjie decoction combined with levothyroxine sodium tablets in treatment of thyroid nodule.Methods From July 2013 to July 2014, 52 cases of thyroid nodule patients were randomly divided into two groups: control group( n=25)and study group(n=27).The control group were received levothyroxine sodium tablets, while the study group were given self-made xiaozhongsanjie decoction on the basis of control group.Both groups were treated for 24 weeks.The changes of thyroid stimulating hormone ( TSH ) , serum free triiodothyronine (FT3), serum free tetraiodothyronine (FT4) levels, and the thyroid nodule size of two groups before and after treatment were recorded and compared.ResuIts After 24 weeks’ treatment, the thyroid nodule size of both groups reduced, and the descending range of study group was much larger than that of control group (P<0.05).The TSH levels of both groups descended, and the descending range of study group was much larger than control group (P<0.05).While the FT4 levels all increased in both groups, and the ascending range of study group was much larger than control group (P<0.05).And the total effective rate of study group was 77.78%, which was significantly higher than control group (48.00%, P<0.05). ConcIusion The therapy of self-made xiaozhongsanjie decoction combined with levothyroxine sodium tablets in treatment of thyroid nodule could control or reduce the thyroid nodule size effectively.

From 1988 — 1990, the plasma 6 — keto —PGF_1. and TXB_2 were detected with radioimmunoassay in 100 cases with various types of viral hepatitis. The results showed thatTXB_2 and 6—keto— PGF_1. increase and PGF~./TXB_2 ratio decreased. There was clear difference as compaied with the normal. The value and PGF_1./TXB_2 ratio were correlated with jaundice, ascits, spontaneous peritonitis,and hepatorenal syndrome.

Objective To construct for the heredity linkage map and to study the functional gene research of Carthamus tinctorius,the factors affecting cDNA amplified fragment length polymorphism(cDNA-AFLP) of C.tinctorius were investigated with developing and optimizing the cDNA-AFLP reaction system.Methods Improved Trizol method was used to extract RNA from compounds in new petals specific to safflower.With the help of M-MLV RTase without RNase activity combined with replacement synthesis method,double-stranded cDNA was synthesized from total RNA;cDNA was digested by restriction enzyme MseI/EcoRI and ligated by two steps.Then the products were provided for pre-amplification and selected amplification of different concentration gradients.After tiny modifications of system concentration,finally PAGE electrophoresis and silver-staining were performed.Results High purity and integrated total RNA for later cDNA synthesis were obtained and high quality cDNA was synthesized with the help of M-MLV RTase without RNase activity combined with replacement synthesis method.The cDNA-AFLP reaction system in C.tinctorius was as follows: 250 ng integrity cDNA was digested thoroughly at 37 ℃ for 6 h,and ligated 12 h at 16 ℃.Furthermore,the sample dilution multiplication was 10 fold for pre-amplification and 150 fold for selected amplification under the proper system concentration.According to the above reaction system,the polymorphous strips with high resolution power in PAGE electrophoresis were clear and stable.Conclusion The cDNA-AFLP reaction system established and optimized in this experiment is suitable for the functional gene analysis of C.tinctorius.

Objective:To study the high-performance liquid chromatographic(HPLC) fingerprints of different germplasms of Flos Carthami.

Objective To monitor the association between the expression of ve-cadherin and mesentery microcirculation blood flow of sepsis CASP rats,Analysis the relationship of each other.Methods Based on the standard criteria,we established sepsis CASP rats,and the rats were divided into several groups according to the gauge of the vein detained needle in the ascending colon,every group has six rats.The groups consisted of Sepsis A group 22 G(0.9 mm× 25 mm,33 ml/min),sepis B group 20 G(1.1 mm ×32 mm,54 ml/min),sepsis C group 18 G(1.3 mm ×32 mm,80 ml/min),sepsis D group 14 G(2.0 mm ×45 mm,270 ml/min),in addition we established the control group.Real-time observation was performed by microscope on the 6 h's blood velcocity of each sepsis CASP rats group.Then we applied the immunohistochemistry to quantitatively analyze the expression of ve-cadherin of each group.Results The blood velcocity of the mesentery microcirculation in control group was (583.21 ±52.39) μm/s,it was higher compared with the sepsis D group(213.30 ±52.39) μm/s (P ＜0.05),the blood velocity in sepsis A group was (482.71 ± 58.62) μm/s,higher compared with the sepsis D group(P ＜ 0.05).The score of the immunohistochemistry quantitative analysis of mesentery ve-cadherin in control group was 11.17 ±0.34,higher compared with the sepsis D group(5.43 ±0.43)(P ＜0.01).The score of sepsis A group was 10.07 ±0.30,higher compared with the sepsis D group(P＜0.05).Conclusions The expression of ve-cadherin of sepsis CASP rats had positive correlation with the blood velocity of the mesentery microcirculation of sepsis CASP rats,and it can indirectly reflect the degree of the sepsis.

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.

Objective To analyze the imaging manifestations of chondromyxoid fibroma,so as to improve diagnostic accuracy.Methods The X-ray,CT and MRI manifestations of 8 cases with chondromyxoid fibroma confirmed by surgical pathology were analyzed retrospectively.Results All of 8 cases were in the long tubular bones.X-ray showed oval,well defined,eccentric,radiolucent lesion with surrounding sclerosis.The thick dense bony or coarse reticular septation were seen in 6 cases.CT scan showed osteolytic,surrounding sclerosis,and 1 case with foci of calcification.MRI images showed a low or medium signal on T1WI,high signal on T2WI,1 case with a equal T1WI and slight high T2WI signal intensity peripheral rim around.Two cases with diffused enhancement on T1WI after intravenous injection of gapentetate acid meglumine injection and a peripheral liner enhancement in 1 case.Conclusion Chondromyxoid fibroma has certain imaging characteristics,but should be combined with X-ray,CT and MRI to differentiate from other bone tumors with similar imaging manifestations.
