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 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.

AIM:To retrospectively analyze the lipid metabolism disturbance and subacute inflammation within the microenvironment of follicular fluid between Chinese polycystic ovarian syndrome ( PCOS ) patients and the controls . METHODS:Serum lipid indexes , steroid hormone levels , and inflammatory cell counts were analyzed .The inflammatory cytokine and apolipoprotein levels were detected in the serum and follicular fluid .The mRNA expression of apolipoproteins and cytokines in the granulose cells was determined by real-time PCR.RESULTS: PCOS patients showed typical obesity accompanied with hyperlipidemia and hyperandrogenemia .Significantly elevated inflammatory cell number and cytokine lev-els were detected in both serum and follicular fluid .The mRNA expression levels of the inflammatory cytokines and apoli-poproteins in the granulose cells from the PCOS patients were higher than those from the controls .CONCLUSION:Elevat-ed apolipoproteins reflect systematic hyperlipidemia in the follicular fluid .Serum lipids and cytokines penetrate follicle-ser-um barrier and get into follicle fluid .Meanwhile , increased intake of apolipoproteins or elevated synthesis of cytokines ( IL-1, IL-6 and TNF-α) by granulose cells could also be crucial to stabilize microenvironment of follicular fluid .Oocyte and subsequent embryos are sensitive to the originaal follicular environment .The lipid metabolism disturbance , inflammatory cell infiltration and hyperandrogenemia may possibly disturb oocyte developmental potential .

BACKGROUND:Problems can occur at the donor site where the autologous tendon graft is taken. Alogenic tissue has become an important graft option for the reconstruction of the anterior cruciate ligament.
OBJECTIVE: To study the clinical curative effect and immune rejection of arthroscopic reconstruction of the anterior cruciate ligament by alogeneic tendon graft.
METHODS:The 120 included patients with anterior cruciate ligament injury were randomized into autologous tendon graft and alogeneic tendon graft groups, respectively, with 60 patients in each group. The autologous semitendinosus-gracilis graft at the affected side or the alogeneic anterior cruciate ligament was implanted into the knee joint in autologous tendon graft group or alogeneic tendon graft group, respectively. Lachman test results, Lysholm and Larson scores of joint function, and postoperative immune rejection were observed and assessed during 2-year folow-up.
RESULTS AND CONCLUSION: Lysholm and Larson scores in autologous tendon graft and alogeneic tendon graft groups were significantly increased after the reconstruction compared with before the reconstruction; however, there was no difference in the scores between both two groups at 2 years after the reconstruction (P > 0.05). At the end of the folow-up, the normal function of the knee joint was restored, and no lag and flexion constraint of the knee joint were observed. No significant differences were observed in Lachman test results between both groups (P> 0.05). Compared with the autologous tendon graft group, immune rejection rates were higher in the alogeneic tendon graft group; however, no significant differences were observed between both groups (P > 0.05). In summary, the alogeneic tendon graft may be a candidate for the reconstruction of the anterior cruciate ligament due to its similar clinical curative effect to the autologous tendon graft and low immune rejection rates.

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.

Pollution and control of microcystins released during the toxic bloom was reviewed in the present paper. As a risk factor in safety assessment, microcystins aroused broad attention. It was a topic of general interest that how to control microcystins reproduction and how to enhance the degradation of microcystins in the water treatment procedure. Based on the state of China, it was considered that a combined method of biological, physical and chemical treatment should be the best way to control microcystins pollution in drinking water.

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.
