[Chemical constituents from Alangium chinense subsp. pauciflorum].

Chemical constituents of 70% ethanol extract of Alangium chinense subsp. pauciflorum were investigated. The 70% ethanol extract of A.

Wound repair using discarded skin tissue from the rolled edge of pressure injury: a feasibility study of five cases.

Introduction: New techniques are needed to manage chronic wounds in patients with contraindications to standard of care treatment.

Objective: This case series investigated the viability and proliferative activity of split skin cells harvested from the discarded rolled edge of PIs for use in promoting reepithelialization in chronic wounds.

Materials And Methods: The harvested skin was minced into particles with a scalpel.

Two new compounds from rhizomes of .

Two new benzo[de]isoquinoline derivatives, 4-phenyl-benzo[]isoquinoline-1,3-dione () and 4-(4-hydroxyphenyl)-benzo[]isoquinoline-1,3-dione (), were isolated from 70% ethanol extract of the rhizomes of . Their chemical structures were elucidated by HRESIMS, 1 D and 2 D spectra.

[Expression analysis of miR164 and its target gene NAC1 in response to low nitrate availability in Betula luminifera].

Nitrogen, an essential macronutrient for the growth and development of plants, affects above- ground biomass accumulation dramatically. Thus, it is very important to reveal the molecular mechanisms of how plants resist or adapt to low nitrogen availability. The NAC1(NAM, ATAF, CUC 1) gene, located in the upstream regulatory network, has been reported to resist low nitrogen by regulating expression of key downstream genes and thus root growth in (Populus tremula × alba).

DNA microarray reveals ZNF195 and SBF1 are potential biomarkers for gemcitabine sensitivity in head and neck squamous cell carcinoma cell lines.

Gemcitabine is a potential chemotherapy drug for treatment of head and neck squamous cell carcinoma (HNSCC), however, the poor or partial response of HNSCC patients to gemcitabine demonstrated the urgent need for gemcitabine biomarkers to improve the therapy. In present work, 10 HNSCC cell lines were employed to figure out the biomarkers for gemcitabine sensitivity. The sensitivities of these 10 cell lines to gemcitabine and the basal expression of these cell lines was investigated, the correlation between gemcitabine response (IC50 dose) and gene expression was investigated by Pearson correlation and FDR estimation.

[Surgical management and reconstruction of petrous internal carotid artery involved in malignant tumors of lateral skull base].

Objective: To investigate the feasibility of reconstruction of internal carotid artery after ablation of malignant tumors in lateral skull base.

Methods: Four male patients with malignant tumors in lateral skull base involved internal carotid artery underwent surgical treatment during Jan 2006 to Jan 2009 were retrospectively analyzed. MRI, CT and DSA were performed in all patients and showed that petrous internal carotid arteries (PICAs) were invaded, with luminal narrow.

[Investigation and analysis on Wenchuan area earthquake trauma to ear, nose and throat].

Objective: The epidemic data of Wenchuan area earthquake trauma of ear, nose and throat were investigated.

Methods: Affected families and sufferers of part of disaster area in Sichuan province in 2008 were investigated with emphasis on severity, cause and treatment of otorhinolaryngologic trauma.

Results: Two hundred and twenty-seven cases of otorhinolaryngologic trauma in survival crowd 3 days after earthquake were included in this study.

[Display of different injuries of recurrent laryngeal nerve in laryngeal electromyography].

Objective: To study the display of different types injuries of recurrent laryngeal nerve (RLN) in laryngeal electromyography (LEMG).

Methods: LEMGs of one hundred and forty-seven patients (147 sides) with traumatic unilateral vocal cord paralysis (UVCP) were studied. After LEMGs, the RLNs exploration operations were performed.
