Objective To evaluate septin-9 and clusterin protein levels in the peripheral blood samples from epithelial ovarian cancer patients, and explore its clinical significance. Methods Clinical data of 200 patients in Cancer Hospital,Chinese Academy of Medical Sciences from Jan. 29, 2008 to Feb. 1,2010 were collected. The peripheral blood samples were obtained from 137 epithelial ovarian cancer patients, 12 borderline ovarian tumor patients, 10 benign ovarian tumor patients, 41 benign pelvic lesion patients and 58 healthy women. The septin-9 and clusterin protein levels in the plasma were measured by double antibody sandwich ELISA or ELISA. The clinical significance of clusterin and septin-9 in plasma was analyzed. The diagnostic efficacy of septin-9 and clusterin protein in the detection of ovarian cancer was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. Results Double antibody sandwich ELISA showed: the mean levels of plasma septin-9 in epithelial ovarian cancer patients or benign pelvic lesion patients were significantly higher than that in healthy women detedted by double antibody sandwich ELISA (P<0.01). The mean levels of plasma septin-9 in epithelial ovarian carcinoma patients with tumor family history or distance metastasis were significantly higher than those patients without (P<0.05). While the expression level of septin-9 protein in peripheral blood of ovarian cancer patients was not related to the patient age, pathologic stage, pathologic differentiation, smoking history, treatment history (including surgery, radiotherapy and chemotherapy) and lymph node metastasis (all P>0.05). ELISA showed: the mean level of plasma clusterin in epithelial ovarian cancer patients was significantly higher than that in healthy women deteded by ELISA (P=0.021). The expression level of clusterin protein in peripheral blood of ovarian cancer patients was not related to the above clinical pathological parameters (all P>0.05). To distinguish between ovarian cancer patients and healthy women by septin-9 protein expression level in plasma, when AUC was 0.712 and cut off was 0.28, the sensitivity of detection ovarian cancer by septin-9 protein expression was 82.5%, and the specificity was 50.0%. To distinguish between ovarian cancer patients and healthy women by clusterin protein expression level in plasma, when AUC was 0.636 and cut off was 87.96 pg/L, the sensitivity of detection ovarian cancer by clusterin protein expression was 71.5%, and the specificity was 41.4%. Conclusions The expression of septin-9 and clusterin protein in peripheral blood of ovarian cancer patients is increased, especially the expression level of septin-9 protein with related to the distant metastasis. The study results shown that the detection of septin-9 and clusterin in plasma has a certain diagnosis value in ovarian cancer, which may be a potential markers for ovarian cancer.

Aim To explore the effeet of puerarin (Pue) on aortic function and blood pressure in hyper-tensive mice induced by high-fat diet.Methods Thirty male mice were divided into five groups named as normal diet group ( Con ) , high-fat diet group (1)10), high-fat diet + low-dose puerarin group (20 mg 'kg-1 •(!"'), high-fat diet + medium-dose puera¬rin (40 mg • kg"1 • d ~1 ) group and high-fat diet + high-dose puerarin group (80 mg 'kg-1 • d~l).Hie mice were injected intraperitoneally with Pue for eight weeks.Body weight, blood pressure and blood glucose were measured.Serum was collected to detect blood lipid.Aortas were separated from aortic endothelial cells to test the vasodilative function.Aortic endotheli¬al cells from 1)10 mice were isolated to perform Iran-swell and cell proliferation experiments.Results I High-rlose puerarin treatment could reduce the body weight, body fat, blood glucose and blood pressure in obese mice ( P < 0.01 ) ; 2 High dose of puerarin could improve the vasodilative function of aortas com¬pared with those from 1)10 mice (P <0.01 ) ; (3) The migration ability of primary endothelial cells from 1)10 + Pue group was improved compared with that from 1)10 group (P <0.01 ).Conclusions Puerarin can significantly reduce blood pressure in obese mice in¬duced by high fat diet by improving the aortic diastolic function and endothelial cell proliferation and migra-tion.

This study was aimed to investigate the effects of different stimulatory factors on proliferation and function of cytokine induced killer (CIK) cells. Peripheral blood mononuclear cells (PBMNC) were separated by Ficoll-Hypacue gradient. According to supplement of different stimulatory factors (CD28 mAb, IL-15 and IL-21), the experiment was divided into five groups:control group (CIK), CB28+IL-15+IL-21 group, IL-15+IL-21 group, CD28+IL-15 group and CD28+IL-21 group. Effects of different stimulatory factors on the proliferation of CIK cells were assayed by an automated hematology analyzer. Changes of granzyme B,perforin and CD107a were detected by flow cytometry. IL-10, IL-12, INF-γ and TNF-α were quantified by ELISA. Cytotoxicities on lung cancer cell line A549, breast adenocarcinoma cell line MFC-7 and human melanoma cell line HME1 were examined by lactate dehydrogenase release method. The results showed that there were significant differences among different groups. The highest proliferation index on days 10 was observed in group CD28mAb, IL-15 and IL-21(255.3 ± 6.3), which was higher than control group, IL-21+IL-15 group and CD28 mAb+IL-21 group (166.6 ± 13.5, 199.4 ± 15.0 and 228.8 ± 16.6) (P < 0.05). The expression of perforin in CD28 mAb+IL-15 group was higher than the other groups. The expression of perforin,GranB and CD107a of costimulatory groups was higher than control group. The cytotoxicities of CD28 mAb+IL-15 group on A549, MFC-7 and HME1 cells (82.2%, 59.3% and 70.6%) were much higher than that of control group (60.9%, 49.6% and 48.4%) (P < 0.05). The highest IFN-γsecretion was found in CD28 mAb, IL-15 and IL-21 groups. It is concluded that there are significant difference of proliferative capacity, cytokine secretion and cytotoxicity after being activated by different stimulatory factors. Adding corresponding stimulatory factors into the culture system displays a great value for target cells culture.

OBJECTIVES: To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN). METHODS: A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021. RESULTS: Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05). CONCLUSIONS Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

Aim To investigate the effect of miR-320a up-regulation on the apoptosis and migration of Bel7402 cells induced by ribonucleic acid Ⅱ.Methods The different expression levels of miR-320a in normal liver cells and hepatocellular carcinoma (HCC) cells were detected by qRT-PCR.Bel-7402 cell was transfected with miR-320a mimic,and the miR-320a expression levels were measured by qRT-PCR.The effect of ribonucleic acid Ⅱ on proliferation of Bel-7402 and Bel-7402-miR-320a cells was measured by CCK-8 assay,and cell cycle and apoptosis were detected by flow cytometry.The migration and invasion ability of ribonucleic acid Ⅱ on Bel-7402 cells were tested by Transwell method.The expression of p53,Cyclin D1,Bax,Bcl-2,MMP-3 proteins were examined by Western blot.Results miR-320a expression levels in HCC cell line Bel-7402 were significantly lower than those in normal cell line HL-7702.Bel-7402 cells were successfully transfected with miR-320a mimic,named Bel-7402-miR-320a.CCK-8 showed that ribonucleic acid Ⅱ could effectively inhibit the proliferation of Bel7402 and Bel-7402-miR-320a cells in vitro in a dosedependent manner at the range of 100,200,300,400,500 mg · L-1.The IC50 of ribonucleic acid Ⅱexposure on Bel-7402 and Bel-7402-miR-320a cells for 12 h and 24 h was 250,200 mg · L-t and 150,120 mg · L-1,respectively;flow cytometric analysis indicated that over-expression of miR-320a could arrest Bel-7402 and Bel-7402-miR-320a cells induced by ribonucleic acid Ⅱ in G0/G1 phase,and promote the apoptosis of HCC cells.Transwell method showed that Bel-7402-miR-320a + Ribonucleic acid Ⅱ group could significantly inhibit the migration of HCC cells compared with control group and Bel-7402 + Ribonucleic acid Ⅱ group.Western blot results showed that the expression of p53,Bax proteins increased,while the Cyclin D1,Bcl-2,MMP-3 proteins were down-regulated in Bel-7402 and Bel-7402-miR-320a cells induced by ribonucleic acid Ⅱ.Conclusions The expression of miR-320a is lower in HCC cells than that in normal cell line.While ribonucleic acid Ⅱ could promote the apoptosis of liver cancer cells by arresting the cell cycle protein expression of Cyclin D1,activating p53 signaling pathway,down-regulating Bcl-2,up-regulating Bax and destroying Bcl-2/Bax proportions,and inhibiting the migration and invasion of HCC cells by downregulating MMP-3.Overexpression of miR-320a could increase the sensitivity and boost the pharmacological effects of ribonucleic acid Ⅱ on HCC cells.

Objective: To investigate the impact of molecular classification and key oncogenes on the oncologic outcomes in patients with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) receiving fertility-preserving treatment. Methods: Patients with EC and AEH undergoing progestin-based fertility-preserving treatment and receiving molecular classification as well as key oncogenes test at Obstetrics and Gynecology Hospital, Fudan University from January 2021 to March 2023 were reviewed. Hysteroscopic lesion resection and endometrial biopsy were performed before initiating hormone therapy and every 3 months during the treatment to evaluate the efficacy. The risk factors which had impact on the treatment outcomes in EC and AEH patients were further analyzed. Results: Of the 171 patients analyzed, the median age was 32 years, including 86 patients with EC and 85 patients with AEH. The distribution of molecular classification was as follows: 157 cases (91.8%) were classified as having no specific molecular profile (NSMP); 9 cases (5.3%), mismatch repair deficient (MMR-d); 3 cases (1.8%), POLE-mutated; 2 cases (1.2%), p53 abnormal. No difference was found in the cumulative 40-week complete response (CR) rate between the patients having NSMP or MMR-d (61.6% vs 60.0%; P=0.593), while the patients having MMR-d had increased risk than those having NSMP to have recurrence after CR (50.0% vs 14.4%; P=0.005). Multi-variant analysis showed PTEN gene multi-loci mutation (HR=0.413, 95%CI: 0.259-0.658; P<0.001) and PIK3CA gene mutation (HR=0.499, 95%CI: 0.310-0.804; P=0.004) were associated with a lower cumulative 40-week CR rate, and progestin-insensitivity (HR=3.825, 95%CI: 1.570-9.317; P=0.003) and MMR-d (HR=9.014, 95%CI: 1.734-46.873; P=0.009) were independent risk factors of recurrence in EC and AEH patients. Conclusions: No difference in cumulative 40-week CR rate is found in the patients having NSMP or MMR-d who received progestin-based fertility-preserving treatment, where the use of hysteroscopy during the treatment might be the reason, while those having MMR-d have a higher risk of recurrence after CR. Oncogene mutation of PTEN or PIK3CA gene might be associated with a lower response to progestin treatment. The molecular profiles help predict the fertility-preserving treatment outcomes in EC and AEH patients.

OBJECTIVETo evaluate the clinical performance of glass fiber reinforced resin-bonded fixed partial denture(GFR-RBFPD) as a periodontal splint on abutment teeth with reduced periodontal support.

METHODSThirty fixed-fixed GFR-RBFPD were delivered to restore anterior partial edentulous dentitions. The adjacent abutment teeth had severely reduced periodontal support and were not indicated for full crown retained FPD. The success rate and functional survival rate had been recorded and the periodontal condition had been evaluated for 4 years. The results were statistically analyzed with single factor variance analysis and chi square test(α=0.05).

RESULTSIn the first, second, and third year following restoration, one connector fractured in each year and they were repaired with adhesive resin and the pontics were kept in place for function. In the third and fourth years after restoration, there was one pontic displacement with fracture of connectors. The total survive rate was 83%(25/30) and the functional survival rate was 93% (28/30) at the end of the fourth year. The main reason of failure was fracture of connector. About 22%(13/60) of the adjacent teeth showed marginal bone height decrease, while the other 78% (47/60) increased with statistic significant difference from one year after the restoration to the end of the observation term(P<0.05). The periodontal condition of the adjacent teeth was improved after the restoration.

CONCLUSIONSThe four years clinical evaluation indicates that the GFR-RBFPD may be used as fixed prostheses to replace lost one to three anterior teeth with reduced periodontal support of abutment teeth.

Due to the large amount of Codonopsis pilosula planted in Weiyuan county,and the arable land area,the local medicinal materials office uses a large amount of manpower,financial resources and material resources to estimate its area every year. In order to extract the information of local Chinese medicinal materials more quickly and simply,we try to apply remote sensing technology to the extraction of Chinese medicinal materials. This paper will use Weiyuan county of Gansu province as the research area,and use the domestic ZY-3 Satellite multi-spectral remote sensing image as the data source to find out the spectral characteristics of the party's participation in other remote sensing images. The visual interpretation method was used to extract the planting area of the C. pilosula in Weiyuan county. The estimated value of the planting area of C. pilosula using satellite remote sensing technology was 75 965 mu( 1 mu≈667 m²),which was basically consistent with the field survey data of the local medicinal materials office. After the accuracy verification,it was found that the precision of C. pilosula planted by visual interpretation was more than 70%. It is concluded that the satellite remote sensing technology can be used to extract the information of C. pilosula and it can provide the relevant information of the planting area of Chinese medicinal materials quickly and accurately.
