OBJECTIVETo study the effect of Compound Ezhu Powder (CEP) on serum levels of CA125 and CA19-9, and the expression of cyclin D protein in endometriosis patients, thus providing theoretical evidence for clinical application of CEP.

METHODSTotally 69 all endometriosis patients underwent surgical treatment at Department of Gynecology and Obstetrics, Tianjin Nankai Hospital from January 2011 to January 2013 were randomly assigned to group A (35 cases) and group B (34 cases). Meanwhile, 30 patients with uterine fibroids who prepared for surgical treatment during the same period were recruited as the control group. Patients in group A took EZP 3 months before surgery. No treatment was given to patients in group B and the control group. The serum CA125 level and the expression of cyclin D in the ectopic endometrium and the eutopic endometrium were detected in the 3 groups before surgery.

RESULTSThe expression of cyclin D was higher in group A and group B than in the control group (P < 0.05). The serum levels of CA125 and CA19-9 were significantly lower in group A than in group B (P < 0.05). The expression of cyclin D in the ectopic endometrium was lower in group A than in group B, but with no statistical difference (P > 0.05). The expression of cyclin D in the eutopic endometrium was significantly lower in group A than in group B with statistical difference (P < 0.05). Meanwhile, the serum CA125 level was positively correlated with the serum CA19-9 level (r = 0.45, P < 0.05).

CONCLUSIONSThe expression of cyclin D obviously increased in endometriosis patients, which was associated with the occurrence of endometriosis. CEP could lower serum levels of CA125 and CA19-9, and down-regulate the expression level of cyclin D, indicating its roles in inhibiting the cell cycle.

Objective To investigate the correlation of BRAFV600E mutation with papillary thyroid carcinoma and coexisting Hashimoto's thyroiditis.Methods A retrospective analysis of clinical characteristics was made in 50 patients with PTC and coexisting HT(research group) and 150 PTC patients(control group) from March,2011 to March,2012,regarding the difference in BRAFV600E mutation.Results In research group,the sensitivity of ultrasound in detecting lymphatic metastasis was 88.9％,while the specificity was 50.0％ ; the levels ofTSH,thyroid globulin antibody,and thyroid peroxidase antibody in research group were higher than those in control group (all P＜ 0.01).Rates of lymphatic metastasis (36.0％ vs 54.0％) and metastasis in Ⅱ-V area(22.2％ vs 63.0％) showed statistically significant differences between research group and control group(P=0.041,P=0.004).The respective rates of mutation of BRAFV600Ein two groups were 34.0％ and 70.7％,showing significant difference (P＜0.01).There was a significant correlation between BRAFV600E mutation and lymphatic metastasis in research group (P ＜ 0.01).Conclusions The sensitivity of ultrasound in detecting lymphatic metastasis of PTC is quite satisfactory while with its poor specificity.Combination of ultrasound with the fast frozen section pathology may help assess the scope of surgery.Reduced BRAF V600Emutation in PTC with coexisting HT results in reduction of lymphatic metastasis and may help to improve the prognosis of patients.

We report the management and maternal and neonatal outcomes of four cases of delayed interval delivery after cervical cerclage in twin pregnancies, who hospitalized in Shanghai First Maternity and Infant Hospital from year 2017 to 2018. Four patients with dichorionic diamniotic twin pregnancies all presented with gradually weakened uterine contractions after spontaneous vaginal delivery of twin 1. After informed consent, the patients received cervical cerclage at 2 to 3 days after delivery when the maternal and fetal conditions were stable, to delay delivery of twin 2. The gestational weeks at delivery of twin 1 were 25 +4, 23 +1, 27 +1, and 23 weeks, which were noted for 30 +1, 32 +6, 31 +4, and 24 weeks for twin 2, respectively. Delayed delivery intervals were 32, 69, 31 and 7 d. Three of the four twin 2 survived, with Apgar score ≥ 8 at 1 minute and birth weight of 1 390, 2 290 and 1 620 g. During a 2-year follow-up, no developmental abnormalities were observed in the children, and no serious maternal complications were found, including severe infection, bleeding or cervical laceration.

Objective To assess the clinical significance of three-dimensional speckle tracking imaging (3D-STI) in the evaluation of left ventricular myocardial function in breast cancer survivors with postoperative anthracycline-based chemotherapy.Methods A total of 51 breast cancer survivors with postoperative anthracycline-based chemotherapy were recruited and 31 female healthy volunteers as the controls.Conventional echocardiography and 3D-STI derived parameters [including global longitudinal strain (GLS) and global area strain (GAS)] were measured before and at 3 and 6 anthracycline-based chemotherapeutic cycles.The receiver operating characteristics (ROC) curve was constructed to determine optimal sensitivity and specificity of 3ID-STI derived parameters for the prediction of future cardiotoxicity.Results In comparison with the controls and baseline cases,GLS and GAS deteriorated significantly (P ＜ 0.05 for both).No statistical difference in GCS and conventional parameters showed before and after the initiation of chemotherapy (P ＜0.05,respectively).The ROC curves showed that GAS as the best 3D-STI predictor of patients who develop cardiotoxicity during the follow-up.The area under ROC(AUC) of GAS was 0.894,and its optimal cut-off value was-28.4％,with a specificity of 88.0％ and a sensitivity of 82.9％.AUC of GLS was 0.802,and its optimal cut-off value was-14.3％,with a specificity of 62.0％ and a sensitivity of 85.4％.Conclusions Early decreases in GAS and GLS based on 3D-STI may allow the prediction of subsequent cardiotoxic development accurately in breast cancer survivors with postoperative anthracycline-based chemotherapy.

Human CD3AK cells were prepared from peripheral blood mononuclear cells by culturing with recombinant IL-2 and antiCD3AK McAb. The mechanism and regulation of CD3AK cytotoxic activity with cytokines (rhIFN-?, rhIFN-?, TNF) and chernotherapeutic agents (CDDP or ADM) were observed by LDH-release assay, ABC-CELISA and the flow cytometric assay. The results showed: (1) Adhesion molecules ICAM-l/LFA-1 participated in CD3AK-mediated killing of tumor cells, hrlFN-? and TNF enhanced cytotoxicity of CD3AK through this pathway. (2) CD3AK could indirectly kill tumor cells by releasing soluable cytotoxic factors. (3) The membrane-associated TNF may be involved in CD3AK-mediated cytotoxicity. (4) CD3AK cells could induce the apoptosis of tumor cells. (5) Pretreatment of tumor cells with CDDP or ADM resulted in the increased vulnerability of tumor cells to CD3AK-mediated killing, the enhancement of CD3AK-mediated cytotoxicity by CDDP was relative to the increased expression of ICAM-1, HLA-ABC on tumor cell membrane.

OBJECTIVE To elucidate the toxicological properties of CdTe quantum dots (CdTe QD) by investigating their effect on mitophagy in human umbilical vein endothelial cells (HUVECs).METHODS The purity of primarily cultured HUVECs was detected by immunofluorescence.Then,HUVECs were incubated with CdTe QD 0.1-100 mg· L-1 for 24 h.After treatment,the cell viability of HUVECs was detected with MT-T assay.The mitochondrial morphology was observed under a laser scanning confocal microscope after labeling with Mitotracker.The treated HUVECs were also labeled with JC-1 probe,and the mitochondrial membrane potential (MMP) was then examined by flow cytometry.The expression of mitophagy-related proteins including microtubule-associated protein 1 light chain 3 Ⅰ /Ⅱ (LC3 Ⅰ /Ⅱ),moesin-like BCL2-induced protein1(Beclin1),phosphatase and tensin (PTEN) homologinduced putative kinase 1(PINK1) and dynamin-related protein Ⅰ (DRP1) was determined by Westem blotting.RESULTS More than 95％ of the cultured cells expressed vascular endothelial cadherin and herein were vascular endothelial cells.The MTT result showed that the cell survival of HUVECs was significantly decreased after incubation with CdTe QD (0.1-100 mg,L-1) for 24 h (P＜0.05,P＜0.01).CdTe QD also induced extensive fragmentation of the mitochondrial network.The results of JC-1 assay showed that CdTe QD (0.1-100 mg· L-1) caused the disruption of MMP.The percentage of HUVECs with higher MMP was reduced from (91.8±0.6)％ in cell control group to (90.2±1.1)％,(84.4±0.9)％ (P＜0.05) and (78.1 ±1.3)％ (P＜0.01),respectively.The Western blotting data suggested that CdTe QD 10 mg·L-1 significantly increased the expression of autophagy-related protein beclin 1 and the ratio of LC3 Ⅱ/LC3 Ⅰ (P＜0.05,P＜0.01),CdTe QD 1 mg· L-1 also raised the level of mitophagy-related proteins like PINK1 and DRP1.CONCULSION CdTe QD can induce mitochondrial dysfunction as well as mitophagy in HUVECs.

Objective Overexpression of multidrug resistance(MDR)is one of the mechanisms that will lead to chemotherapy failure.Of the MDR pathways in tumor cells,P-glycoprotein (P-gp) encoded by MDR genes is one of the key points.99Tcm-methoxyisobutylisonitrile(MIBI) is an imaging agent that can detect overexpression of MDR in tumor cells.The aim of this study was to observe the relationship between 99Tcm.MIBI uptake kinetics and P-gp levels in tumor cells,with or without MDR reversing agents.Methods A totle of 2×106 cells of human myelogeneous leukemia cell line K562 and its resistant subline(K562/D) were incubated with 8 MBq 99Tcm-MIBI respectively.99Tcm-MIBl accumulation and emux at various time inter-vats and the uptake difference with the presence of different cyclosporin A(O.1-O.4 ug/ml)were also ob-served.Comparison of different cell lines or without and with cyclosporin A were performed with the t-test, and the daa of different groups were compared by q-test.Results 99Tcm-MIBI uptake in K562 and K562/D cell line were 1.559±0.529 and 0.107±0.036,99Tcm-MIBI uptake in k562 was flitleon times higher than k562/D.As compared with K562 cell line with no expression of P-gp,significantly increased the 99Tcm-MIBI uptake of K562/D to 106%,148% and 163%after treated with cyclosporin A(0.1,0.2.0.4ug/ml)was ob-served(t=4.35,4.83,5.88,P<0.05).Conclusiom 99Tcm-MIBI uptake can reflect the P-gP level and multidrug-resistance inhibitor may impact 99Tcm-MIBI uptake in P-gP overexpressing cells.
