(Orchidaceae, Aeridinae), a new subalpine epiphytic orchid from the Mountains of Southwest China.

, a new orchid species from the Balang Mountain, Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles , but differs in having shorter stems, a reniform epichile and a sub-hemispherical hypochile (spur), obtuse-rounded at the apex. The results of molecular phylogenetic analyses based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA markers (K, A-H, M-D and L-F) from 50 species indicate that is closely related to and , also endemic to the Hengduan Mountains.

(Orchidaceae, Epidendroideae), a new species from southwest China, based on molecular and morphological evidence.

is described as a new orchid species from Wenchuan County, Sichuan Province of southwest China. It is morphologically similar to , but it differs from the latter in having branched stems, slightly fleshy strap-shaped leaves, longer inflorescences with 3-6 flowers and a capitate gynandrium with a lip-shaped mouth opening. Its species status is also supported by molecular phylogenetic analyses, based on nuclear ribosome internal transcribed spacer (nrITS) and three chloroplast DNA fragments (K, A-H and L-F), which showed distinct systematic boundaries from the most morphologically similar and their morphological relatives and .

A new infrageneric classification of (Orchidaceae: Epidendroideae) based on molecular and morphological data.

is an orchid genus containing 73 species of mainly epiphytic on trees or rocks in mountain forests of tropical and subtropical Asia. Previous phylogenetic analyses and morphological assessments have failed to produce a well-resolved phylogeny at the infrageneric level. In the present study, a new infrageneric classification of is proposed based on thoroughly morphological and phylogenetic analyses based on 52 species.

Cetuximab or nimotuzumab in combination with chemotherapy for treating recurrent/metastatic nasopharyngeal carcinoma: A meta‑analysis and systemic review.

The present study aimed to evaluate the effectiveness and safety of cetuximab (CTX) or nimotuzumab (NTZ) in combination with chemotherapy for patients with recurrent and/or metastatic nasopharyngeal carcinoma (RM-NPC), and for this purpose, a single-group rate meta-analysis was performed. A systematic search of the Cochrane library, Pubmed, EMBASE, Chwina National Knowledge Infrastructure and WanFang databases for studies published until February 15, 2022 was performed. The 1-, 2-, 3- and 5-year overall survival (OS) rates were the primary endpoints.

 (Primulaceae), a new species of the primrose from Sichuan, China.

This paper describes and illustrates a new species of Primulaceae, from Wolong National Nature Reserve in Sichuan Province, China. It is very rare and currently only known from its type locality. The new species belongs to subsection Chartacea of the section Petiolares on account of lacking bud scales at flowering, being efarinose and having distinct petiolate leaves with more or less rounded lamina.

Inflorescences of T.P. Yi and T.P. Yi (Poaceae, Bambusoideae) shed light on the taxonomy of the Sino-Himalayan alpine bamboos.

The taxonomy of the Sino-Himalayan alpine bamboos is controversial due to their complex evolutionary history and further complicated by the scarcity of inflorescence. Here, we supplement the description of the inflorescence of T.P.

 (Orchidaceae, Epidendroideae), a new species from Sichuan, China, based on molecular and morphological data.

(Orchidaceae), a new orchid species from Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles and , but differs markedly from the former in having a thinner and slightly rolled downwards reniform epichile and the central thickened purple-red mat with irregular folds (vs. subtriangular epichile curves upwards, with 2 thick, brown to purplish-brown median ridges from base to apex), and can be clearly distinguished from the latter by having reniform epichile with lobed apex and subconical hypochile with bilobed apex that splits into two conical protrusions (vs.

Comparative Chloroplast Genomics of Seven Endangered Species and Phylogenetic Relationships of Orchidaceae.

The species in the genus (Orchidaceae) are considered endangered, mainly distributed in the temperate regions of the Northern Hemisphere, with high ornamental and economic value. Despite previous extensive studies based on both morphology and molecular data, species and sections relationships within remain controversial. Here, we employed two newly generated chloroplast genomes with five other published genomes to elucidate their genomic characteristics.

A systemic analysis on pemetrexed in treating patients with breast cancer.

Background: This systemic analysis was conducted to evaluate the efficacy and safety of pemetrexed based chemotherapy in treating patients with metastatic breast cancer as first or second line chemotherapy.

Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for patients with breast cancer were identified using a predefined search strategy. Pooled response rate (RR) of treatment were calculated.
