Objective:To evaluate the safety and efficacy of a palliative regimen of computed tomography (CT)-guided 125I seed im-plantation combined with chemotherapy for recurrent ovarian cancer. Methods:A total of 21 patients with recurrent ovarian cancer, who received 125I seed implantation and chemotherapy, were retrospectively analyzed. Out of the 29 lesions detected, 25 lesions were suitable for 125I seed implantation. Treatment planning system (TPS) was implemented preoperatively to determine the number and dis-tribution of 125I seeds. Under CT guidance, 125I seeds were implanted into the recurrent lesions using the TPS. Within 3 d of 125I seed im-plantation, liposomal paclitaxel was administered by intravenous infusion on day 1 and carboplatin by infusion via the feeding artery of tumor on day 2. Chemotherapy was repeated on a 21-day schedule. Efficacy and complications were evaluated during follow-up. Re-sults:After two cycles of chemotherapy, out of the 25 recurrent lesions that underwent 125I seed implantation, four lesions showed com-plete remission, 14 with partial remission, three with stable disease, and four with progression of disease. The objective response rate was 72%, and the pain relief rate was 82.4%. Karnofsky's performance status scores increased dramatically (P=0.019). The median pro-gression-free survival time was 6.8 months, median overall survival time was 14.2 months, and the 1-year survival rate was 42.9%. He-matologic toxicity and gastrointestinal reactions were the primary adverse conditions. No severe radiation complications and treat-ment-related deaths were observed in all patients. Conclusion:CT-guided 125I seed implantation combined with chemotherapy is active and well-tolerated in patients with recurrent ovarian cancer. This combined treatment cannot only significantly enhance the objective re-sponse rate, but also leads to remarkable improvement in cancer-related symptoms.

Objective:To investigate the correlation of plasma D-dimer levels with the response to first-line chemotherapy and the prognosis of patients with serous ovarian cancer (SOC). Methods:The preoperative plasmic D-dimer levels of 143 patients with prima-ry SOC were retrospectively evaluated. The patients were admitted to Tianjin Medical University Cancer Institute and Hospital between January 2008 and May 2010. The patients were divided into two groups on the basis of plasmic D-dimer levels. Group A consisted of 100 patients with a normal plasmic D-dimer level of≤0.3 mg/L. Group B included 43 patients with an increased plasmic D-dimer level of>0.3 mg/L. The correlations of the different plasmic D-dimer levels with clinicopathological features, therapeutic effects, and surviv-al outcomes were further analyzed. Results:The plasmic D-dimer levels were positively correlated with the staging of the Federation of International Gynecology and Obstetrics, residual tumor size, presence of malignant ascites, preoperative serum CA125 level, and neo-adjuvant chemotherapy. Group B exhibited a significantly lower (P<0.001) complete response (CR) rate of 34.88%(15/43) than group A, which yielded a CR rate of 73.00%(73/100). The progression-free survival and overall survival rates of group B were significantly lower than those of group A (25.58%vs. 50.00%and 32.56%vs. 65.00%;P<0.05). Multivariate analysis revealed that the plasmic D-di-mer level is an independent prognostic factor associated with unfavorable prognosis. Conclusion:Increased preoperative plasmic D-di-mer levels may be a potential biomarker of weak responses to first-line chemotherapy and poor clinical outcomes in patients with SOC.

OBJECTIVETo investigate the impact of 1, 25-(OH)2D3 on left ventricular hypertrophy (LVH) in type 2 diabetic rats.

METHODSType 2 diabetic mellitus (DM) model rats were established by intraperitoneally injecting with 30 mg/kg streptozotocin. After 8 weeks, 19 male rats were identified as diabetic with left ventricular hypertrophy (LVH) by ultrasound examination, and randomly assigned into three groups: untreated (DM-LVH, n=7), treated with insulin (DM-LVH+INS, n=6), and treated with 1, 25-(OH)2D3 (DM-LVH+VD, n=6). Healthy male rats were used as the controls group (n=6). The fasting blood glucose and the insulin level were determined weekly. The left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor level were determined by 4 weeks later.

RESULTSIn the DM-LVH model group, the insulin level was significantly decreased compared with the non-diabetic control group (P<0.05), whereas the blood glucose, left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor expression were significantly increased (all P<0.05). In the DM-LVH+INS and DM-LVH+VD groups, the insulin levels were significantly increased compared with the DM-LVH model group (P<0.05), whereas the other parameters were significantly decreased (all P<0.05).

CONCLUSION1, 25-(OH)2D3 could reverse LVH in diabetic rats and that the mechanism may involve stimulating insulin secretion and reducing blood glucose via direct up-regulation of 1, 25-(OH)2D3-receptor expression.

OBJECTIVETo analysis the genetic mode of Rh DEL phenotype and RHD 1227A allele in Zhejiang Han population through family investigations.

METHODSRh DEL phenotypes were identified by a serologic adsorption-elution method. Two polymerase chain reaction-sequence specific prime (PCR-SSP) methods which detectED RHD 1227A allele and Rhesus hybrid box, respectively, and a nucleotide sequencing method focused on the exon 9 of RHD 1227A allele were employed to determine the zygosity of RHD allele.

RESULTSAll five probands with Rh DEL phenotype harbored a RHD 1227A allele and had a RHD allele deletion, and they were RHD 1227A/RHd heterozygote. One of the parent members was found to contain a RHD 1227A allele and a normal RHD allele in pedigree 1, 2 and 3, respectively. Thus, they were RHD 1227A/RHD heterozygotes and presented normal D positive phenotype. The son of proband No 1. inherited the RHD 1227A allele and presented a normal D positive phenotype due to a RHD 1227A/RHD heterozygote; The offsprings of proband No. 2, No. 4, and No. 5 did not inherit RHD 1227A allele and presented a normal D positive phenotype.

CONCLUSIONRHD 1227A allele is an important genetic marker of Rh DEL phenotype; RHD 1227A is recessive to normal RHD allele and dominant to RHd allele; RHD 1227A allele is an ancestral, but not a spontaneously mutated allele.

OBJECTIVETo investigate the material base and underlying mechanism of the effect of cluster needling of scalp acupuncture on the neuronal plasticity in rats with focal cerebral infarction.

METHODSThe model rats with acute cerebral infarction were made by blocking the middle cerebral artery with monofilament. One hundred and thirty two Wistar rats were randomly divided into 4 groups: sham-operation group (A), model group (B), point-to-point scalp acupuncture group (C) and cluster-needling of scalp acupunture group (D). Puncturing from "Baihui (GV 20)" to "Qubin (GB 7)" was used in group C. Cluster needling of scalp acupuncture was used in group D, in which needles were inserted forward and slantingly into "Baihui (GV 20)" and its left and right sides at 4 mm. In both groups, the treatment was carried out with rapid twirling reinforcing-reducing for 1 min then retaining needle for 30 min, once a day, 6 days in one course, for treating 4 courses. There was no treatment for group A and B. The change of neurological function was evaluated with Bederson score, while the expression of microtubule-associated protein 2 (MAP-2) in the ischemic penumbra was examined with immunohistochemistry (streptavidin-peroxidase method).

RESULTSIn comparison,with group B, the score of neurological function in group D decreased on 7th day (P<0.05), while the scors in group C and D also decreased on 14th and 28th days (both P<0.05). As compared with group C, the score of neurological function in group D obviously decreased on 28th days (P<0. 05). Comparing with group B, the expression of MAP-2 on the ischemic cortex was significantly increased in group D and C on 7th, 14th and 28th days (all P<0. 05), however, this expression in group D was higher than that in group C on 14th and 28th days (P<0. 05).

CONCLUSIONCluster needling of scalp acupuncture can improve the neurological function of rats with focal cerebral infarction, and increase the expression of MAP-2 in the ischemic penumbra.

Objective To investigate the characteristics and clinicopathologic significance of microlymphatic vessel in breast cancer.Methods The microlymphatic density(MLD)and lymphatic vessel invasion(LVI)in 102 cases of breast cancer tissue were evaluated by immunohistochemical staining,using monoclonal antibody for podo- planin.The characteristic of microlymphatic vessel and the relationship between MLD,LVI and clinicopathological parameters were evaluated.And blood vessels were also detected with CD34 by double-labeling immunohistochemis- try for confirming the specificity of podoplanin for microlymphatic vascular.Results Podoplanin antibody was spe- cific for lymphatic vessel without intersection with blood vessel.The density and morphology of microlymphatic ves- sel in breast cancer had significant heterogeneity.The MLD in breast cancer tissues was significantly higher than that in normal breast tissues.The microlymphatic vessel that in breast cancer tissues indicated by a more irregular shape and a larger open lumen,and some cancer embolus entering the open microlymphatic vessel could be seen. MLD was significantly correlated with LVI(P

OBJECTIVETo evaluate the roles of plasma mast cell carboxypeptidase and chymase in the diagnosis of allergic diseases by measuring the contents of both in children.

METHODSA total of 59 children with allergic diseases and 53 healthy children were recruited into the study. Plasma levels of mast cell carboxypeptidase and chymase were measured using ELISA.

RESULTSThe plasma levels of mast cell carboxypeptidase and chymase in children with allergic children were 1.089 ± 0.752 ng/mL and 0.905(0.375-2.318) ng/mL, respectively, which were significantly higher than those in healthy children [0.593 ± 0.380 ng/mL and 0.454 (0.097-1.077) ng/mL respectively; P<0.05]. There was a significantly positive correlation between plasma mast cell carboxypeptidase and chymase levels in children with allergic diseases (r=0.684, P<0.01).

CONCLUSIONSPlasma levels of mast cell carboxypeptidase and chymase increase in children with allergic diseases, suggesting that mast cell carboxypeptidase and chymase may serve as the indexes for the diagnosis of allergic diseases.

OBJECTIVE The eradication of cancer stem cells(CSCs)is signifcant for cancer therapy and prevention.METHODS In this study,we evaluated WM130,a novel derivative of matrine,for its effect on CSCs using human hepatocellular carcinoma(HCC)cell lines,their sphere cells,and sorted EpCAM+cells. RESULTS We revealed that WM130 could not only inhibit proliferation and colony formation of HCC cells, but also suppress the expression of some stemness-related genes and up-regulate some mature hepatocyte marker genes, indicating a promotion of differentiation from CSCs to hepatocytes. WM130 also suppressed the proliferation of doxorubicin-resistant hepatoma cells, and markedly reduced the cells with CSC biomarker EpCAM.Moreover,WM130 suppressed HCC spheres,not only primary spheres but also subsequent spheres,indicating an inhibitory effect on self-renewal capability of CSCs.Interestingly,WM130 exhibiteda remarkable inhibitory preference on HCC spheres and EpCAM+cells rather than their parental HCC cells and EpCAM- cells respectively. In vivo, WM130 inhibited HCC xenograft growth, decreased the number of sphere-forming cells, and remarkably decreased the levels of EpCAM mRNA and protein in tumor xenografts. Better inhibitory effect was achieved by WM130 in combination with doxorubicin.Further mechanism study revealed that WM130 inhibited AKT/GSK3β/β-catenin signaling pathway. CONCLUSION Collectively, our results suggest that WM130 remark-ably inhibits hepatic CSCs, and this effect may via the down-regulation of the AKT/GSK3β/β-catenin pathway.These findings provide a strong rationale for the use of WM130 as a novel drug candidate in HCC therapy.
