Laparoscopic Cholecystectomy in Patients With History of Gastrectomy.

Background And Objectives: Patients with previous gastrectomy have an increased incidence of gallstones and gallbladder morbidity requiring surgery. We investigated the possible risk factors that contribute to severe gallbladder disease in patients with previous gastrectomy and the role of laparoscopic cholecystectomy (LC) in the treatment of these patients.

Methods: In this retrospective study, we reviewed a database of patients who underwent LC in our hospital during the period January 1, 2010, through May 1, 2015.

Laparoscopic ligation of proximal splenic artery aneurysm with splenic function preservation.

Splenic artery aneurysm is one of the most common visceral aneurysms, and patients with this type of aneurysm often present without symptoms. However, when rupture occurs, it can be a catastrophic event. Although most of these aneurysms can be treated with percutaneous embolization, some located in uncommon parts of the splenic artery may make this approach impossible.

Myeloid dendritic cells loaded with dendritic tandem multiple antigenic telomerase reverse transcriptase (hTERT) epitope peptides: a potentially promising tumor vaccine.

Human telomerase reverse transcriptase (hTERT) has been identified as an ideal tumor-associated antigen (TAA). Use of a synthetic hTERT epitope peptide to pulse dendritic cells can induce autologous T cell anti-tumor immune responses, but such responses induced by a single epitope peptide have been shown to be weak and a narrow-spectrum. Here, we designed dendritic tandem multiple antigenic peptides (MAPs) containing the following three hTERT epitope peptides: I540, V461 and L766, which are HLA-A*02-, HLA-A*24- and HLA-RDB1*04/11/15-restricted, respectively.

Role of high-intensity focused ultrasound in treatment of hepatocellular carcinoma.

About 70 per cent of patients with hepatocellular carcinoma are diagnosed at intermediate or advanced stages, and most of them are technically unresectable. As a novel, emerging therapeutic modality, high intensity focused ultrasound (HIFU) has a great potential for tumor treatment. In this review, principle of HIFU technique is introduced, and an overview of clinical applications and limitations of HIFU for HCC treatment, as well as prospects for future development, is provided.

[CTLs induced by hTERT-related multiepitope peptide-sensitived mDCs specifically kill HLA-A24+ tumor cells].

Aim: To study the antigen specific anti-tumor effect of cytotoxic T lymphocytes(CTLs), which was induced by human telomerase reverse transcriptase (hTERT)-related multiple epitope peptides impulsed myeloid dendritic cells(mDCs), against human leukocyte antigen (HLA)-A24(+) tumor cells.

Methods: Four branches of multiple antigen peptides (MAPs) of hTERT epitopes and three separate peptides were solid-phase artificially synthesized, phlebotomize peripheral blood from HLA-A24(+) healthy volunteers, sorted the blood through MACS MicroBeads and cultured mDCs, Nylon fiber column purified T lymphocytes, mDCs impulsed with each type of peptides were co-cultured with T lymphocytes to induce CTLs specifically killing effect, and the resultant CTLs were used as effector cells, SMMC-7721 with hTERT and HLA-A24 positive and SKOV3 which are hTERT-positive but HLA-A24-negative tumor cells were used as target cells. The level of human IL-12, TNF-α in the culture supernatant was determined by ELISA.

[Changes in bio-availability of immobilized Cu and Zn bound to phosphate in contaminated soils with different nutrient addition].

Bio-availability of Cu and Zn fixed by phosphate in contaminated soils with application of nutrients were measured by pot experiment. It was simulated for the third national standardization of copper and zinc polluted soils by adding copper and zinc nitrate into red and paddy soils, respectively and together. Phosphate amendment was added to the soils to fix Cu and Zn, then added KCl and NH4Cl or K2SO4 and (NH4)2SO4 fertilizers following to plant Ryegrass, which was harvested after 40 d.

[Effects of different cooling rates on cryopreservation of hematopoietic stem cells from cord blood].

Clinical evidence of hematopoietic restoration with umbilical cord blood (UCB) grafts indicates the UCB can be a useful source of hematopoietic stem cells for routine bone marrow reconstitution. Considering (10 +/- 5) x 10(8) nucleared cells per cord blood unit, there is a potential limitation for the use of cord blood in adults, which, however, can be overcome by ex vivo expansion of cells. A prerequisite for expansion is the significantly higher recovery of MNC, CD34+ cells and colony-forming cells (CFC) by thawing cryopreserved MNC.
