A Web-based database is developed to provide psycholinguists with a large-scale phonological representation system for all Mandarin Chinese monosyllables. The construction of the system is based on the slot-based phonological pattern generator (PatPho), with an adequate consideration of the language-specific features of the Chinese phonology. Users can retrieve the relevant phonological representations through an interactive query system on the Web. The query outcomes can be saved in a number of formats, such as Excel spreadsheets, for further analyses. This representation system can be used for a variety of purposes—in particular, connectionist language modeling and, more generally, the study of Chinese phonology.

Aims

The International Association of Diabetes and Pregnancy Study Groups (IADPSG) proposed that a one-time value of fasting plasma glucose of 5.1 mmol/l or over at any time of the pregnancy is sufficient to diagnose gestational diabetes. We evaluated the repercussions of the application of this threshold in pregnant Han Chinese women.

Methods

This is a retrospective study of 5360 (72.3% of total) consecutively recruited pregnant Han Chinese women in one centre from 2008 to 2011. These women underwent a two-step gestational diabetes diagnostic protocol according to the previous American Diabetes Association criteria. The IADPSG fasting plasma glucose criterion was used to reclassify these 5360 women. The prevalence, clinical characteristics and obstetric outcomes were compared among the women classified as having gestational diabetes by the previous American Diabetes Association criteria (approximately 90% were treated), those reclassified as having gestational diabetes by the single IADPSG fasting plasma glucose criterion (untreated), but not as having gestational diabetes by the previous American Diabetes Association criteria, and those with normal glucose tolerance.

Results

There were 626 cases of gestational diabetes defined by the previous American Diabetes Association criteria (11.7%) and these cases were associated with increased risks of maternal and neonatal outcomes when compared with the women with normal glucose tolerance. With the IADPSG fasting plasma glucose criterion, another 1314 (24.5%) women were reclassified as having gestational diabetes. Gestational diabetes classified by the IADPSG fasting plasma glucose criterion was associated with gestational hypertension (P = 0.0094) and neonatal admission to nursery (= 0.035) prior to adjustment for maternal age and BMI, but was no longer a predictor for adverse pregnancy outcomes after adjustment.

Conclusion

The simple IADPSG fasting plasma glucose criterion increased the Chinese population with gestational diabetes by 200%. The increased population with gestational diabetes was not significantly associated with excess obstetric and neonatal morbidity.

  The concept of a “core parent” was proposed by breeders to describe elite lines with both good field performance and high potential for breeding superior new lines. Guichao 2 is one of the most important rice core parents in China. In the present study, Simple Sequence Repeat marker (SSR) based genome-wide screening was performed for Guichao 2, its parents and derivatives to study the genetic diversity and structure of them. A total of 348 polymorphic markers and 833 polymorphic alleles were detected. The Polymorphic Information Content (PIC) value ranged from 0.15 to 0.95 and averaged 0.39. Genetic similarity among the ten varieties varied from 0.751 to 0.926 with an average of 0.842, indicating that the genetic diversity is not abundant. At the whole genome level, Chaoyangzao 18 (30.4%) contributed many more genetic components to Guichao 2 than Guiyangai 49 (16.3%) did. The amount of genetic material transmitted by Guichao 2 to its derivatives varied from 49.7% (Qingliuai) to 59.5% (Fengqingai), with an average of 54.7%. In addition, 78 genomic regions of Guichao 2 were identified as stably inherited by these derivatives, with contribution ratios ranging from 14.29 to 85.71%, with an average of 47.25%. Ten of these regions with the same contribution ratio of 85.1% (RM3412-RM140, RM1339-RM1068, RM6997-RM6172, RM3524-RM3042, RM1388-RM1136, RM1353-RM1243, RM5508-RM3753, RM3395-RM3662, RM3662-RM44 and RM6643-RM2915) were found to be significantly important in the derivative cultivars.
