Analysis of Chemical Components in the Roots of Eight Intersubgeneric Hybrids of Paeonia.

Paeonia cultivars are famous ornamental plants, and some of them are also traditional Chinese medicinal resources. Intersubgeneric hybrids of Paeonia (IHPs) are formed by the hybridization of herbaceous peony (Paeonia lactiflora) and tree peony (Paeonia×suffruticosa or lutea hybrid tree peony). The phenotypic characteristics of IHPs are similar to those of herbaceous peony, and their root systems are large and vigorous.

Characterization of phytochemicals in the roots of wild herbaceous peonies from China and screening for medicinal resources.

Paeonia Radix Rubra (PRR) is a very common traditional Chinese medicine (TCM). The roots of Paeonia lactiflora and Paeonia anomala subsp. veitchii are used for the production of PRR.

Identification of a novel allele, HLA-B*52:01:24, by sequence-based typing in a Chinese individual.

HLA-B*52:01:24 has one synonymous nucleotide change from HLA-B*52:01:01:01 at nucleotide 384 (codon 104 Glycine).

Correlation Between Cephalometric Measures and End-of-Treatment Facial Attractiveness.

Sixty-nine experienced Chinese orthodontists evaluated 108 Chinese patients' facial attractiveness from set of photographs (frontal, lateral, and frontal smiling photos) taken at the end of orthodontic treatment. These 108 patients, which contained an equal number of patients with Class I, II, and III malocclusion, were randomly selected from 6 orthodontic treatment centers throughout China. Spearman rank-order correlation coefficients (rs) analyses were performed to examine agreement in ranking between all judge pairs.

[Validation of subjective and objective evaluation methods for orthodontic treatment outcome].

Objective: To assess the correlations between objective measurements of 108 finished orthodontic cases and subjective assessments made by 69 orthodontic specialists, to explore the statistically significant measuring categories of cast and cephalogram and to validate the regression model.

Methods: A stratified random sample of 108 cases was drawn from the large sample of 2 383 patients who finished orthodontic treatment between July 2006 and August 2008 in six orthodontic treatment centers around China. For each patient, the post-treatment information sources evaluated in this study included standardized plaster study casts and a lateral cephalometric X-ray image.

Psychometric properties of the Chinese version of the Pediatric Quality Of Life Inventory 4.0 Generic Core scales among pediatric cancer patients.

Background: The Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales are commonly used to assess health-related quality of life of healthy children and pediatric patients. Validation of the Generic Core Scales among Chinese pediatric cancer patients has not been reported in the literature.

Validation of the Chinese version of the Children's Revised Impact of Event Scale (CRIES) among Chinese adolescents in the aftermath of the Sichuan Earthquake in 2008.

Objective: This study examined the psychometric properties of the 13-item Chinese version of the revised Impact of Event Scale for Children (CRIES) among 3160 high school students in Chengdu, China, 1 month after the Sichuan Earthquake in 2008.

Methods: Participants self-administered a structured questionnaire in classroom settings. Posttraumatic stress symptoms (using the Chinese version of the CRIES) and other psychological variables, including depression, anxiety, thoughts of physical threat, and earthquake-related experiences, were measured.

Factor structure and psychometric properties of the Connor-Davidson Resilience Scale among Chinese adolescents.

Objectives: Resilience refers to psychological characteristics that promote effective coping and positive adaptation in adversity. This study investigated the factor structure and psychometric properties of the Chinese version of the Connor-Davidson Resilience Scale (CD-RISC) among adolescents.

Methods: A total of 2914 Chinese adolescents living in Chengdu, Sichuan, completed the CD-RISC 1 month after the 2008 Sichuan earthquake.

Coping mediates the association between Type D personality and perceived health in Chinese patients with coronary heart disease.

Background: Increasing evidence show that Type D personality is a risk factor for morbidity, mortality, and quality of life of patients with coronary vascular disease. Few studies examined coping as a potential behavioral mechanism to explain the harmful effect of Type D personality.

Purpose: This study examined the association between Type D personality, coping, and perceived health among Chinese patients with coronary heart disease (CHD).

Validation of the Chinese version of the Pediatric Quality of Life Inventory (PedsQL) Cancer Module.

Objective: The psychometric properties of the Chinese version of the Pediatric Quality of Life Inventory (PedsQL) Cancer Module were investigated.

Methods: This instrument and the Generic Core Scales were administered to 359 pediatric patients with cancer (5-18 years) and 413 parents of such patients (2-18 years old).

Results: Seven and eight factors were, respectively, identified for the patient and parent versions.

Application of the Type D Scale (DS14) in Chinese coronary heart disease patients and healthy controls.

Objective: To examine the psychometric properties of the Type D Scale (DS14) in mainland China.

Methods: One hundred and seventy-eight coronary heart disease (CHD) patients and 376 healthy controls were recruited. They completed the Chinese version of the DS14, the Zung Self-Rating Depression Scale, the Positive Affect and Negative Affect Scale, the Perceived Social Support Scale, and the Social Avoidance and Distress Scale.
