Traditional Herbal Medicine: A Potential Therapeutic Approach for Adjuvant Treatment of Non-small Cell Lung Cancer in the Future.

Lung carcinoma is the primary reason for cancer-associated mortality, and it exhibits the highest mortality and incidence in developed and developing countries. Non-small cell lung cancer (NSCLC) and SCLC are the 2 main types of lung cancer, with NSCLC contributing to 85% of all lung carcinoma cases. Conventional treatment mainly involves surgery, chemoradiotherapy, and immunotherapy, but has a dismal prognosis for many patients.

A key to the males of from China is provided.

Cytogenic and molecular studies of male infertility in cases of Y chromosome balanced reciprocal translocation.

Y-autosomal translocation has been previously reported in association with male infertility; however, the mechanisms of Y-autosomal translocation and non‑obstructive azoospermia or severe oligospermia remain unclear. G‑banding and fluorescence in situ hybridization (FISH) were performed to analyze the translocation of chromosomes, and a single nucleotide polymorphism (SNP) genotyping assay was used to test mutations. The present study describes three new cases with a de novo balanced translocation t(Y;13), t(Y;9) and t(Y;6).

[Establishment of an internal control for directed differentiation using pluripotent stem cell lines derived from heterozygotic twins].

Objective: To reprogram amniotic fluid cells into pluripotent stem cells in order to create an optimal internal control model for directed cell differentiation.

Methods: Human amniotic fluid-derived cells (hAFDCs) from heterozygotic twin fetuses were induced by retroviral vectors encoding Oct4, Sox2, c-Myc and Klf4. In vivo pluripotency, differentiation capacity and karyotype of hAFDCs induced pluripotent stem cells (hAFDCs-iPSCs) were determined.

[Clinical and prognostic significance of preoperative serum CA153, CEA and TPS levels in patients with primary breast cancer].

Objective: To investigate the clinical and prognostic values of preoperative serum CA153, CEA and TPS levels in patients with primary breast cancer.

Methods: A total of 386 hospitalized patients with stage I ∼ IV breast cancer from Nov 1998 to Feb 2009 were followed up, and their clinicopathological data were analyzed retrospectively to determine the factors affecting their prognosis.

Results: First, preoperative serum CA153 expression level was significantly associated with the age of onset and tumor size (P < 0.

[Patch diversity and spatial structure of wild Thymus quinquecostatus].

With the combination of ISSR (inter-simple sequence repeats), SRAP (sequence-related amplified polymorphism) and spatial autocorrelation, the genetic diversity and spatial structure per unit patch of three Huaiyuan populations of Thymus quinquecostatus in southeast China were analyzed. The results showed that there existed higher levels of genetic and clonal diversity among the patches within the wild T. quinquecostatus populations, with the percentage of polymorphic loc being 75.

Objective: To establish a protocol for culturing of human embryonic stem cells (HUES4) without any animal-derived feeder cells and to investigate the karyotype stabilities of HUES4 cells after long-term cultivation.

Methods: HUES4 cells were cultured on mitomycin C treated MEFs or human foreskin fibroblast feeder cells. The pluripotency of the ES cells was analyzed by immunocytochemistry staining to detect the expression of pluripotent marker, karyotype of the ES cells at passage 27, 34, 41, 44 and short tandem repeat (STR) at passage 27 were analyzed.
