and are closely-related genera for which 'inflorescence' structures were incompletely understood and difficult to reconcile. After re-examining the inflorescence morphology, the so-called 'spikelets' of both genera as described should instead be recognised as pseudospikelets with mostly inactive axillary buds. The new bamboo taxa, comprising two varieties of a new species, are placed in , representing a new genus record for China and Vietnam.

and are closely related to bamboo genera. However, when considered with newly discovered and morphologically similar material from China and Vietnam, the phylogenetic relationship among these three groups was ambiguous in the analyses based on DNA regions. Here, as a means of investigating the relationships among the three bamboo groups and exploring potential sources of genomic conflicts, we present a phylogenomic examination based on the whole plastome, single-nucleotide polymorphism (SNP), and single-copy nuclear (SCN) gene datasets.

A new phenolic derivative () and a new dihydrophenanthrene () were isolated from the aerial part of rofe, along with 12 known compounds. The structures of the new compounds were elucidated by spectroscopic analysis,and the relative configuration of compound was determined by -based configuration analysis (JBCA) method. Bioassay result indicated that compound exhibited weak antibacterial activity against and .

Treatment with high iodine concentrations can delay oncogenic activation effects, reduce cell growth and return thyroid-specific gene and protein expression levels to normal. During rearranged during transfection (RET)/papillary thyroid carcinoma (PTC) 3 activation, excess iodine can act as a protective agent in thyroid follicular cells. The chemokine receptor CCR7 serves a critical role in lymphocyte trafficking into and within lymph nodes, the preferential metastatic site for PTC.

The miR-200 family was recently identified as a suppressor of epithelial-mesenchymal transition (EMT). The loss or gain of miR-200 family members is associated with cancer invasion. The epidermal growth factor receptor (EGFR) is overexpressed in the majority of anaplastic thyroid cancers (ATCs).

Objective: To explore the expressions of SARI (suppressor of AP-1, regulated by IFN) and connective tissue growth factor/cysteine-rich 61/nephroblastoma-1 (CCN1) and clarify their influences on the occurrence, development and prognosis of colorectal carcinoma (CRC).

Methods: Real-time PCR (polymerase chain reaction) was used to confirm the expressions of SARI and CCN1 at the mRNA level in 32 fresh tissue samples. And the expressions of Caco-2, HT-29 and Lovo were also detected by RT-PCR (reverse transcription-PCR) in cell lines.

Aim: To evaluate the effect of human telomerase reverse transcriptase (hTERT) gene antisense oligodeoxynucleotide (As-ODN) on telomerase activity and cell apoptosis in colon cancer cell line SW480.

Methods: As-ODN was transfected into cells SW480 by liposomal transfection. Cultured cells were divided into three groups: ASODN (5'GGAGCGCGCGGCATCGCGGG-3'), sense oligodeoxynucleotide (5'-CCCGCGATGCCGCGCGCTCC-3', S-ODN) and control.

Aim: To investigate the expression and significance of PTEN, hypoxia-inducible factor-1 alpha (HIF-1alpha), and targeting gene VEGF during colorectal carciogenesis.

Methods: Total 71 cases colorectal neoplasms (9 cases of colorectal adenoma and 62 colorectal adenocarcinoma) were formalin fixed and paraffin-embedded, and all specimens were evaluated for PTEN mRNA, HIF-1alpha mRNA and VEGF protein expression. PTEN mRNA, HIF-1alpha mRNA were detected by in situ hybridization.

Aim: To investigate the relationship between the mast cell density (MCD) and the context of clinicopathological parameters and expression of p185, estrogen receptor (ER), and proliferating cell nuclear antigen (PCNA) in gastric carcinoma.

Methods: Mast cell, p185, ER, and PCNA were detected using immunohistochemical S-P labeling method. Mast cell was counted in tissue of gastric carcinoma and regional lymph nodes respectively, and involved lymph nodes (ILN) were examined as usual.
