Identifying Modifiable Risk Factors for Relapse in Patients With Schizophrenia in China.

Background: Preventing relapse of schizophrenic patients is really a challenge. The present study sought to provide more explicit evidence and factors of different grades and weights by a series of step-by-step analysis through test, logistic regression analysis and decision-tree model. The results of this study may contribute to controlling relapse of schizophrenic patients.

Mutational analysis of the gene in Chinese men with nonobstructive azoospermia.

As a crucial transcription factor for spermatogenesis, GATA-binding protein 4 (GATA4) plays important roles in the functioning of Sertoli and Leydig cells. Conditional knockout of GATA4 in mice results in age-dependent testicular atrophy and loss of fertility. However, whether GATA4 is associated with human azoospermia has not been reported.

[Ecological benefits of Gastrodia elata-Phallus impudicus sequential planting pattern].

Gastrodia elata is a kind of precious traditional Chinese medicine. In the process of cultivation of G. elata, due to the influence of continuous cropping obstacles and other factors, the fungus materials and land that have been planted with G.

Effects of cooling rates and ice-seeding temperatures on the cryopreservation of whole ovaries.

Purpose: The aim of this study was to detect the effects of different cooling rates and different ice-seeding temperatures on the cryopreservation of whole ovaries.

Methods: Cow whole ovaries were slowly frozen using different protocols with different cooling rates and different ice-seeding temperatures. Follicular viability was assessed using the trypan blue test; the percentage of morphologically normal primordial follicles and the follicular densities of grafts were measured.

Cryopreservation of whole ovaries with vascular pedicles: vitrification or conventional freezing?

Purpose: To compare the efficacy of vitrification and conventional freezing of whole ovaries.

Methods: Ovaries obtained from 5-year-old female bovines were cryopreserved by conventional freezing, rapid freezing and vitrification. The ovarian cortical strips were cryopreserved by conventional freezing.
