Cotyledonary somatic embryo is one kind of intermediate material similar to callus in the process of in vitro tissue culture from Rosa hybrida 'John F. Kennedy'.

Background: Rose is recognized as an important ornamental plant worldwide, and it is also one of the most widely used flowers in gardens. At present, the improvement of rose traits is still difficult and uncertain, and molecular breeding can provide new ideas for the improvement of modern rose varieties. Somatic embryos are quite good receptors for genetic transformation.

Ultrasonic Features of Uncommon Congenital Heterotopic Colon and Pancreas in the Neck: An Extremely Rare Case Report.

Congenital heterotopic colon and pancreas localized to the neck has not been reported. Herein, we describe an extremely uncommon case of congenital heterotopic colon and pancreas aberrantly presented within a cyst on the neck, and the thickened wall of the cyst on ultrasound may represent an important ultrasonic feature.

[Systematic review and Meta analysis on the effectiveness and safety of in treatment of functional constipation].

Objective: To review systematically the effectiveness and safety of (Chinese massage)in treatment of functional constipation.

Methods: The articles on functional constipation treated with were collected by computer retrieval from 7 databases from the date of establishment to March 28, 2020, including Chinese biomedical literature database (SinoMed), China journal full-text database (CNKI), full-text database of Wanfang academic journals (Wanfang), VIP Chinese science and technology journal database(VIP), PubMed, Dutch medical literature database (EMbase) and the Cochrane Library. After data extraction and quality evaluation of the included articles, Meta analysis was conducted with RevMan5.

Prevalence, awareness, treatment, and control of hypertension among very elderly Chinese: results of a community-based study.

The epidemiologic distribution of hypertension among very elderly Chinese is still not clear. This study aimed to investigate the prevalence, awareness, treatment, and control rate of hypertension among very elderly in Chengdu. From May 2013 to May 2015, a total of 1056 participants from 20 residential communities were sampled.

Epithelioid inflammatory myofibroblastic sarcoma in abdominal cavity: a case report and review of literature.

In this study, we present a rare and difficult case of epithelioid inflammatory myofibroblastic sarcoma (EIMS) in abdominal cavity. A 47-year-old female presented as left upper abdominal pain for 6 months and abdominal distention for 1 month. CT examination showed a solid mass in the left upper intra-abdomen.

[PAR-1 regulation of intracellular Ca²(+) mobilization in pulmonary giant cell carcinoma cell line PLA801D/PLA801C].

Objectives: To investigate molecular mechanisms of PAR-1 regulation on intracellular Ca²(+) mobilization in lung giant cell carcinoma cells in vitro and its involvement in tumor metastasis.

Methods: Free intracellular Ca²(+) ([Ca²(+)]i) was measured in lung giant cell carcinoma PLA801C and PLA801D cells by confocal microscopy. Sense and anti-sense PAR-1 expression vectors were transfected into PLA801C (C+)and PLA801D(D-) cells, respectively.

[Expression of PAR-1 in human lung carcinoma and its relationship with tumor metastatic potential].

Objective: To explore the correlation between expression of PAR-1 and metastasis of human lung carcinoma.

Methods: Expression levels of PAR-1 were examined in surgically resected lung carcinoma specimens and corresponding lymph nodes by RT-PCR and immunohistochemistry, combined with morphometric methodology and clinicopathologic profiles.

Results: Strong PAR-1 staining was detected in the periphery of carcinoma nests, adenocarcinomatous emboli, foci of atypical adenomatous hyperplasia adjacent to the adenocarcinoma and atypical proliferation of duct epithelium of bronchial mucous glands.

[Transplantation of fetal cardiomyocyte regenerates infarcted myocardium in rats].

Objective: To investigate the feasibility and efficiency of fetal cardiomyocyte transplantation into the rat model of myocardial infarction.

Methods: Cardiomyocytes were isolated from aborted human embryos aged 12 - 16 weeks and cultured for 5 days to confirm their viability. Rat model of extensive myocardial infarction (MI) was established in 18 male Wistar rats by ligating the descending anterior branch of left coronary artery and the 18 rats were randomly divided into 2 groups: transplantation group (n = 7, 2 x 10(6) fetal cardiomyocytes were transplanted into the myocardial scar) and culture medium injection group (n = 6, culture medium was injected into the myocardial scar) 5 days after extensive MI was caused.
