Mutation analysis and prenatal diagnosis of EXT1 gene mutations in Chinese patients with multiple osteochondromas.
Multiple osteochondromas (MO), an inherited autosomal dominant disorder, is characterized by the presence of multiple exostoses on the long bones. MO is caused by mutations in the EXT1 or EXT2 genes which encode glycosyltransferases implicated in heparin sulfate biosynthesis. ⋯ Mutation analysis of two MO families in this study demonstrates its further application in MO genetic counseling and prenatal diagnosis.

Utility of squamous cell carcinoma antigen, carcinoembryonic antigen, Cyfra 21-1 and neuron specific enolase in lung cancer diagnosis: a prospective study from China.
Early detection and diagnosis is urgent for the sake of effective treatment strategy for lung cancer. However, a convenient, economical and relatively precise method is not available. We here report a prospective study to find the possible value of the combined use of four popular tumor markers in the early diagnosis of lung cancer among patients with suspicious nodules in the lung. ⋯ SCC, CEA, Cyfra 21-1 and NSE are valuable in the early diagnosis of lung cancer among suspicious nodules in the lung, especially when they were assayed together for one patient.

Management with the insufficient proximal landing zone for endovascular repair in aortic dissection.
Sufficient length of the proximal landing zone (PLZ) is the key for a successful thoracic endovascular aortic repair (TEVAR) of an aortic lesion. The aim of this research was to investigate the safety, feasibility, efficacy, and problems of endovascular repair for aortic dissection with insufficient PLZ. ⋯ The procedure for extending an insufficient PLZ for endovascular repair for aortic arch pathology is feasible and relatively safe. The applicability of TEVAR in such aortic disorders may be expanded.

A diagnosis-based health economic analysis of postural orthostatic tachycardia syndrome in Chinese children.
Postural orthostatic tachycardia syndrome (POTS) is a common clinical problem in children and adolescents. The previous diagnostic approach to POTS of children and adolescents is based on a series of tests to exclude all other causes, which is time and medical resource consuming. Recently, a new diagnostic approach has been developed. The present study was designed to statistically analyze the results of clinical investigation items and the cost for the diagnosis of POTS in children patients, and evaluate cost changes in the diagnosis of POTS. ⋯ The cost of POTS diagnosis has been declined in recent years, but the cost of exclusive diagnosis is still its major part.

Calcineurin is involved in cardioprotection induced by ischemic postconditioning through attenuating endoplasmic reticulum stress.
Ischemic postconditioning (I-postC) is a newly discovered and more amenable cardioprotective strategy capable of protecting the myocardium from ischemia/reperfusion (I/R) injury. Endoplasmic reticulum (ER) is a principal site for secretary protein synthesis and calcium storage. Myocardial I/R causes ER stress and emerging studies suggest that the cardioprotection has been linked to the modulation of ER stress. The aim of the present study was to determine whether cardioprotection of I-postC involves reduction in ER stress through calcineurin pathway. ⋯ I-postC protects myocardium from I/R injury by suppressing ER stress and calcineurin pathways are not associated with the I-postC-induced suppression of ER stress-related apoptosis.
