Objective To evaluate the effects and toxicities of the hyperthermic peritoneal peffusion with oxaliplatin (L-OHP) and interleukin-2 (IL-2) combined with chemotherapy for treatment malignant asci-tes. Methods 42 patients with malignant aacites from assimilation system tumor were catheterized,drained and flushed with L-OHP 85 mg/m2 in 2 000 ~2 500 ml of 5 % glucose and IL-2(2 MU),NRL-001 Double RF tumor hyperthermia system was applied to heat the abdominal part for 60 ~ 120 minutes at an intraperitoneal temperature of 41 -43 ℃ ,next day,all the patients were treated with calcium folinate(CF)0. 2 g/m2 by 2 hours intravenous infusion,5-fluorouracil (5-FU) 0. 4 g/m2 intravenously, followed by 46 hours continuous infusion of 5-FU (1 600 mg/m2), 2 weeks a cycle. Results The overall response rate was 66. 67%, including CR : 6 cases, PR:22 cases, NC:6 cases, and PD:8 cases. MST is 5.6 months. The main toxicity was impatient abdomen ache,paralysis intestinal obstruction. Conclusion Hyperthermic peritoneal perfusion with oxaliplatin and inter-leukin-2 combined with chemotherapy is efficient and safe in the treatment malignant ascites and can improve the quality of life. It is worthing wildly using and research.

Objective:To prepare dendritic cell (DC)-cytokine induced killer (CIK) tumor vaccine using DCs of patients with nonsmall-cell lung cancer (NSCLC) harboring autologous tumor antigens and to observe its inhibitory effect on autologous tumor cells in vitro. Methods: Peripheral blood mononuclear cells (PBMCs) extracted from NSCLC patients were cultured into DCs and CIKs in presence of different cytokines. Cancer cells from the patients were cultured in vitro and were used to prepare different tumor antigens: tumor cell lysates, necrotic tumor cells and normally-grown tumor cells. The DCs were stimulated by OK-432 and the phenotypes of the DCs were analyzed by flow cytometer. Then the DCs were co-cultured with CIKs. The anti-tumor effect of DC-CIK was evaluated by MTT assay. Results: Compared with the DCs harboring the antigens of necrotic tumor cells and normally-grown tumor cells, DCs pulsed with tumor cell lysates had significantly higher expression of surface molecules such as CD1a (85.1?2.7), CD80 (80.0?4.4), CD83 (75.4?5.3), and HLA-DR(80.5?7.8, all P

The importance of structural variants(SVs)for human phenotypes and diseases is now recognized.Although a variety of SV detection platforms and strategies that vary in sensitivity and specificity have been developed,few benchmarking procedures are available to confidently assess their performances in biological and clinical research.To facilitate the validation and application of these SV detection approaches,we established an Asian reference material by characterizing the genome of an Epstein-Barr virus(EBV)-immortalized B lymphocyte line along with identified benchmark regions and high-confidence SV calls.We established a high-confidence SV callset with 8938 SVs by integrating four alignment-based SV callers,including 109x Pacific Biosciences(PacBio)continuous long reads(CLRs),22 x PacBio circular consensus sequencing(CCS)reads,104x Oxford Nanopore Technologies(ONT)long reads,and 114×Bionano optical mapping plat-form,and one de novo assembly-based SV caller using CCS reads.A total of 544 randomly selected SVs were validated by PCR amplification and Sanger sequencing,demonstrating the robustness of our SV calls.Combining trio-binning-based haplotype assemblies,we established an SV benchmark for identifying false negatives and false positives by constructing the continuous high-confidence regions(CHCRs),which covered 1.46 gigabase pairs(Gb)and 6882 SVs supported by at least one diploid haplotype assembly.Establishing high-confidence SV calls for a benchmark sample that has been characterized by multiple technologies provides a valuable resource for investigating SVs in human biology,disease,and clinical research.

Researches on detection of human papillomavirus (HPV) high-risk samples were carried out by poly-merase chain reaction (PCR) coupled with microchip electrophoresis (MCE). Herein, we introduced a simple, rapid, automated method for detecting high-risk samples HPV16 and HPV18. In this research, general primers were initially selected to obtain sufficient detectable yield by PCR to verify feasibility of MCM method for HPV detection, then type-specific primers were further used to evaluate the specificity of MCE method. The results indicated MCE method was capable of specifically detecting high-risk HPV16 and HPV18, and also enabled simultaneous detection of multiplex samples. This MCE method described here has been successfully applied to HPV detection and displayed excellent reliability demonstrating by sequencing results. The inherent capability of MCE facilitated HPV detection conducted in a small chip with automated, high throughput, massive parallelized analysis. We envision that MCE method will definitely pave a way for clinical diagnosis, and even on-site screening of cervical cancer.
