(Primulaceae), a new species from Yunnan, China.

A new species, , is described and illustrated. In gross morphology, it is clearly allied to section Petiolares and is most similar to from the group , but is distinctive in its indumentum in the throat of the corolla tube, and the markedly stoloniferous habit.

A novel nude mouse model for studying the pathogenesis of endometriosis.

Endometriosis is a common female gynecological disease that is characterized by the presence of functional endometrial tissue outside the uterine cavity. At present, many animal models have been established. However, previous studies consistently use human endometrial tissue implanted in the subcutaneous or abdominal cavity for modeling and rarely use endometrial cells.

Three new species of (Orchidaceae: Malaxideae) from Southwest China based on morphological characters and phylogenetic evidence.

and , two new species from the karst region of southwestern China, and , a new species from montane region in Yunnan, are described and illustrated. is easily distinguished from its relatives by having abaxially purple leave with purple reticulate veins prominent adaxially, a lip auriculate at base, and falcate-lanceolate pollinia. is closely related to and but differs from them by having an ovate to broadly ovate leaf, purple lip and apex connate along the margins.

New contributions to Goodyerinae and Dendrobiinae (Orchidaceae) in the flora of China.

Eight new species from China, , , , , , , and , are described and illustrated. differs from by having 5-9 irregular and papillae-like calli on each side in the sac of the lip, epichile with entire lobes, petals narrowly obliquely obovate and an apex that is not recurved. is easily distinguished from its relatives similar by having a long stem, pubescent ovary and sepals, epichile lobes with irregular and undulate margins, a subquadrate callus without teeth in the saccate hypochile.

Four new species of (Gesneriaceae) in Yunnan province, China.

Four new species of (Gesneriaceae) are described and illustrated. These new species grow in pairs in montane forests in Yunnan province, China. One pair grows in Wenshan county, Southeast Yunnan, viz.

, a new species of Gesneriaceae from southwestern China.

A new species of , from Yunnan province of southwestern China, is described and illustrated here. morphologically closely resembles and , but differs in vegetative and generative characters. Differences between the new species and others species occurring in Yunnan Province are also shown in the identification key.

, a new species of Gesneriaceae from Yunnan, China.

is a new species of Gesneriaceae from Yunnan, China and is described and illustrated here. It is morphologically similar to , and , but the congeners of this new taxon can be distinguished by several salient characters. A description of , together with illustrations and photographs, a distribution map and conservation assessment are presented.

Growth of human colon cancer cells in nude mice is delayed by ketogenic diet with or without omega-3 fatty acids and medium-chain triglycerides.

Background: Tumors are largely unable to metabolize ketone bodies for energy due to various deficiencies in one or both of the key mitochondrial enzymes, which may provide a rationale for therapeutic strategies that inhibit tumor growth by administration of a ketogenic diet with average protein but low in carbohydrates and high in fat.

Materials And Methods: Thirty-six male BALB/C nude mice were injected subcutaneously with tumor cells of the colon cancer cell line HCT116. The animals were then randomly split into three feeding groups and fed either a ketogenic diet rich in omega-3 fatty acids and MCT (MKD group; n=12) or lard only (LKD group; n=12) or a standard diet (SD group; n=12) ad libitum.

[Screening of differentially expressed microRNAs in borderline and malignant gastrointestinal stromal tumors].

Objective: Gastrointestinal stromal tumors (GISTs) have a broad spectrum of biological behaviors ranging from benign, borderline and malignant. This study aimed to screen differentially expressed microRNAs (miRNAs) between malignant and borderline GISTs and to investigate the potential role of miRNAs in the malignant transformation of GISTs.

Methods: Six GIST samples including borderline tumors (n = 3) and malignant tumors (n = 3) were collected based on the clinical and pathological characteristics.

[Staging and histologic grading of gastrointestinal stromal tumors].

Objective: To investigate the clinical stage and histological grade of gastrointestinal stromal tumors.

Methods: Twelve clinical and pathological parameters were assessed in 613 patients with follow-up information. These parameters were classified into two gross spread parameters including liver metastasis and peritoneal dissemination, five microscopic spread parameters including lymph node metastasis, vascular, fat, nerve and mucosal infiltration, and five histological parameters including mitotic count ≥ 10 per 50 high-power fields, muscularis propria infiltration, coagulative necrosis, perivascular pattern and severe nuclear atypia.

[Detection of KRAS gene mutation and its clinical significance in colorectal adenocarcinoma].

Objective: To explore the clinical significance of KRAS mutation detection in colorectal adenocarcinoma.

Methods: Paraffin-embedded tissue specimens were obtained from 440 patients with colorectal adenocarcinoma. The genomic DNA was extracted.
