Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.

Objective Gynecologic minimally invasive surgery has become popular in the treatment of tumor therapy in re-cent years, but improper application can result in tumor metastasis.In this paper, we presented 6 uterine neoplasm cases of tumor me-tastasis after minimally invasive surgery and analyzed the causes and the preventive measures. Methods Retrospective analysis was made on the clinical data and pathology characteristics of the 6 uterine neoplasm cases of tumor metastasis after primary minimally inva-sive surgery in our department from January 1, 2013 to 2015 June 30, and related literature were reviewed. Results The ages of 6 patients were 39-52 years old.The primary operation methods included 2 cases of hysteroscopic myomectomy, 3 cases of laparoscopic myomectomy and 1 case of radiofrequency ablation.The pathological diagnosis after primary operations were 4 cases of uterine sarcoma ( low grade endometrial stromal sarcoma in 2 cases and leiomyosarcoma in 2 cases) who were found metastatic tumor at 3-16 months after primary surgery and finally died of the disease and 2 cases of uterine fibroids who were found metastatic tumor in abdominal cavity and puncture hole at 60 months and 108 months respectively after primary operation followed by a good prognosis after the second surgi-cal resection. Conclusion Owing to uterine neoplasm by hysteroscopy, laparoscopy often needs certain pressure and morcellation which may result in easy plantation of crushing tumor tis-sue or metastasis with circulation and puncture under pressure.Ra-diofrequency ablation lack of histopathologic diagnosis has heating effect which is inclined to speed up the spread and transfer of tumor cells once it is diagnosed as malignant.Therefore, clinicians should know the defects and risk of being lack of histopathologic diagno-sis, diagnostic curettage pathology and fast pathology to avoid tumor metastasis induced by minimally invasive surgery.

Objective To develop a real-time polymerase chain reaction(PCR)system to determine transcriptional level of MexAB-OprM multidrug efflux pump gene and to investigate the impact of androgra- pholide on MexAB-OprM gene transcription in Pseudomonas aeruginosa.Methods The fragments of mexB gene of mexAB-oprM operon and 30S rRNA gene rpsL were amplified and cloned into two plas- mids respectively.These plasmids were used as external standards for real-time PCR.Real-time PCR was applied to measure the mRNA transcripition of mexB and rpsL gene in Pseudomonas aeruginosa growing in medium with different concentrations of andrographolide.Results The plasmids for standard curve were constructed successfully.The relative mexB mRNA expressions in 50,100,150 and 200?g/mL andrographolide were 0.04?0.03,0.06?0.07,0.09?0.03 and 0.04?0.03 respectively, which were significantly lower than that in the control(0.24?0.04,P0.05).Conclusion Andrographolide can reduce the transcriptional level of MexAB-OprM,which may he one mechanism for its anti-infection effect.

Objective To evaluate the method of detecting antibodies to Bacillus anthracis by enzymelinked immunosorbent assay(ELISA)using crude antigen.Methods The anti-Bacillus anthracis antibody levels in sera of 42 healthy people and 42 patients were detected by indirect ELISA.Standard curve was plotted using the data from positive controls,based on which the relative content of each serum was calculated and compared with the result of rLF.Results The median of antibody's relative content in patient group and healthy people group are 1.19 and 0.24,the differences being statistically significant(uc=7.643,P＜0.05).The result of crude antigen is in concordance with rLF(but not parallel absolutely).Conclusions Crude antigen can distinguish most of patients with healthy population effectively.The results suggested that crude antigen is applicable in anti-Bacillus anthracis antibody surveillance.

In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

OBJECTIVETo investigate serum level and gene polymorphisms of matrix metalloproteinase 9 (MMP-9), and platelet glycoprotein VI (GPVI) in patients with acute coronary syndrome (ACS).

METHODSIn a prospective study of 179 patients with documented ACS and 164 controls, we measured baseline serum MMP-9 levels using ELISA and determined the MMP-9/C-1562T and MMP-9/G5564A genotypes using PCR-restriction fragment length polymorphism. Fib serum level was measured by Clauss assay. We also analyzed the Fib/Bbeta-148C/T and GPVI/T13254C polymorphisms.

RESULTSSerum levels of MMP-9 and Fib in ACS patients were significantly higher than in controls (P < 0.001), and serum level of Fib in the acute myocardial infarction group was higher than in patients with unstable angina (P < 0.05). No significant difference between ACS patients and controls was found in frequencies of MMP-9/C-1562T, MMP-9/G5564A, Fib/Bbeta-148C/T, and GPVI/T13254C genotypes and alleles (P > 0.05). The T allele of the Fib/Bbeta-148T polymorphism was associated with increased plasma Fib level (P < 0.05). There was a strong positive correlation between serum level of MMP-9 and Fib (r = 0.289, P < 0.01).

CONCLUSIONSerum levels of MMP-9 and Fib were independent risk factors of ACS. There was an obvious relationship between the Bbeta-148C/T mutation and high Fib level. No significant difference between controls and ACS patients was found in the frequencies of MMP-9 C-1562T and G5564A, Fib Bbeta-148C/T and GPVI T13254C genotypes and alleles (P > 0.05).
