Objective To establish the quality standard of Shilong Qingxue Effervescent Granules. Method Rhizoma curcuma, flos sophorae, cornus officinalis and gamdir vine in Shilong Qingxue Effervescent Granules were identified by TLC. The content of gastrodin in Shilong Qingxue Effervescent Granules was determined by HPLC. Results The TLC spots were highly clear without the interference of negative samples and were reproductive. A good linear for gastrodin was in the range of 14～70 ?g/mL (r=0.999 9). The average recovery was 97.33% (RSD=0.63%). Conclusion This method is simple, rapid and accurate, and can be used for the quality control of Shilong Qingxue Effervescent Granules.

Hepatitis virus NAT reagents are now widely used clinically. However, the qulity of domestic and foreign NAT reagents varies dramatically. The main reasons for these differences including the manufacture technique, test principle and assay procedure were discussed in this paper and current status of the quality control of the NAT reagents were also described. Finally, it was pointed out that strengthening public supervision and laboratory internal control are very important for the quality improvement of the domestic reagents.

Objective: To investigate the expression of vasculogenic mimicry (VM) in endometrial carcinoma tissues and its rela-tionship with the clinicopathologic features and prognosis of the disease. Methods: A total of 267 paraffin-embedded endometrial carci-noma specimens of patients with complete follow-up data were collected from the Shijiazhuang Bethune International Peace Hospital between January 2005 and June 2014. CD31-PAS dual staining was performed to identify the VM structure. Tissue samples were then divided into VM-positive and VM-negative groups. CD133 expression was detected by immunohistochemical streptavidin peroxidase method. Results: Among the 267 endometrial carcinoma patients, 65 cases (24.3%) were VM positive. VM formation was closely corre-lated with the International Federation of Gynecology and Obstetrics Staging (χ2=9.987, P=0.002), histodifferentiation grade (χ2=11.795, P=0.001), myometrial invasion depth (χ2=5.499, P=0.019), vascular cancer embolus (χ2=22.599, P<0.001), and lymph node me-tastasis (χ2=7.848, P=0.005). Kaplan-Meier survival curve analysis showed that survival time was significantly shorter in the VM-posi-tive group (median survival time was 51 months) than in the VM-negative group (median survival time was 100 months) (χ2=70.973, P<0.001). Moreover, CD133 expression was significantly higher in the VM-positive group [75.4% (49/65)] than in the VM-negative group [58.9% (119/202)] (χ2=5.720, P=0.017). Conclusion: VM is closely correlated with the pathogenesis, development, and malignancy of endometrial carcinoma. Furthermore, VM is one of the important indexes influencing the prognosis of this disease. Therefore, CD133-positive cells may contribute to VM formation.

OBJECTIVE:To analyze the rationality of the preventive use of antibiotics in Chinese ophthalmologic patients with type Ⅰ incision.METHODS:By means of retrospective study,a total of 1 273 ophthalmologic cases from 113 hospitals of 2006～2007 from National Monitoring Network of Ministry of Health for Clinical Application of Antibiotic with type Ⅰ incision involving preventive administration of antibiotics via different routes were analyzed.RESULTS:The local administration (eye drops and local injection) was rational on the whole,but the systemic administration (intravenous or oral administration) was irrational to some degree in which the drug grade was on the high side,the antibacterial spectrum was inappropriate,and the medication time was delayed.CONCLUSION:Preoperative local administration and rational use of dosage forms should be emphasized in the preventive use of antibiotics for patients undergoing ophthalmologic surgery.

Objective To evaluate the function of vascular endothelial growth factor (VEGF) and other clinical indexes to forcast ovarian hyperstimulation syndrome (OHSS). Method Collecting the serum and follicular fluid (FF) of 42 cases in the in vitro fertilization and embryo transfer (IVF-ET) cycles and then analysis the relationship of the clinical and detected indexes between the OHSS (10 cases) and the non-OHSS (32 cases). Results The concentration of VEGF in FF?E 2 on the day of human chorionic gonadotropin (hCG) injection, basal luteinizing hormone (LH) and the number of ovum retried much higher in the OHSS than in the non-OHSS. Conclusions The concentration of VEGF in FF of OHSS cases is higher than that of controls, supporting the role of VEGF as a mediator of OHSS. Therefore VEGF in FF is a forcast index of OHSS.

Objective To construct the eukaryotic expression vector of HBEBP2 gene,and screen the exonic genes of proteins in hepatocytes interacting with HBEBP2.Methods The DNA fragment of HBEBP2 was amplified by PCR.The eukaryotic expression vector pGBKT7-HBEBP2 was constructed successfully by yeast-two hybrid system 3 and then transformed into yeast cells AH109.The transformed AH109 were then mated with yeast cells Y187 containing hepatic cDNA library plasmid.The diploid yeast cells were plated on synthetic dropout nutrient medium(SD/-Trp/-Leu/-His/-Ade) containing X-?-gal for the first selection.Library plasmids pACT2-DNA were extracted and co-transformed into yeast cell AH109 together with pGBKT7-HBEBP2.Then the yeast cells were plated on synthetic dropout nutrient medium(SD/-Trp/-Leu /-His/-Ade) containing X-?-gal for the second screening to eliminate false positive clones.The real positive clones were sequenced and analyzed by bioinformatics.Results Six proteins binding to HBEBP2 were screened,including human sapiens lactate dehydrogenase D,human sapiens mitochondrion,human sapiens mannose,human sapiens aldehyde oxidase,human sapiens serpin peptidase inhibitor and other two unknown proteins.Conclusions A novel class of proteins in hepatocytes interacting with HBEBP2 has been obtained.It is presumed that HBEBP2 protein is correlated with glycosylation,lipid metabolism and cell proliferation,etc.

Objective To evaluate the appl ication of CT perfusion in intra-axia l disease. Methods By applying a nuclear medicine data processi ng technique to the time-density data obtained from dynamic CT, cerebral tissue perfusion was p e rformed in 8 cases, 4 with normal findings, 2 with ischemic cerebrovascular dise ase, and 2 with gliomas. Cerebral blood perfusion maps was created and analyzed, absolute regional cerebral blood volume, regional cerebral blood flow, and mean transit time were determined and analyzed as well. Results Wit h regard to var ious degrees of perfusion impairment within the ischemic territory, thus giving rise to a very heterogenous appearance. As a rule, the center of a lesion usuall y representing the core of ischemia showed marked reduction of blood flow. At th e outer margin of a tumor area, the reduction of CBF and CBV was often less pron ounced, indicating some residual flow via collaterals, as was confirmed by the b olus delay on the time to peak time. Conclusion In the near fut ure, functional imaging techniques should have a major impact on therapeutic decision-making i n acute stroke patients, perfusion CT may be recommended even now for emergency applications in daily patient care due to its practicability.
