ABSTRACT
As the pioneer of the Green Revolution in China, Guangdong province witnessed the improvement and spread of semi-dwarf Xian/Indica rice cultivars and possessed diverse rice germplasm of landrace and cultivars. A total of 517 accessions containing a core germplasm of 479 newly sequenced landraces and modern cultivars were used to reveal breeding signatures and key variations for regional genetic improvement of indica rice from Guangdong. Four subpopulations were identified in the collection, which including Ind IV as a novel subpopulation that not covered by previously released accessions. Modern cultivars of subpopulation Ind II were inferred to have less deleterious variations, especially in yield related genes. About 15 Mb genomic segments were identified as potential breeding signatures by cross-population likelihood method (XP-CLR) of modern cultivars and landraces. The selected regions spanning multiple yield related QTLs (quantitative trait locus) which identified by GWAS (genome-wide association studies) of the same population, and specific variations that fixed in modern cultivars of Ind II were characterized. This study highlights genetic differences between traditional landraces and modern cultivars, which revealed the potential molecular basis of regional genetic improvement for Guangdong indica rice from southern China.
ABSTRACT
Objective@#To explore the effect of simulated family ward in training and management of illiterate rural peritoneal dialysis catheter patients.@*Methods@#Between January 2013 and December 2013 in our department, 80 patients with peritoneal dialysis catheter rural illiteracy as the research object, using the random number table method, the patients can be divided into the experimental group and control group, 40 cases of control group accepted traditional way standard training, the experimental group adopted simulation training family ward as the carrier, two groups of patients were carried out by the same pd specialist nurse training, the control group patients take traditional 7 days training courses for training, the experimental group according to the characteristics of the illiterate patients, an interactive learning mode of explanation-demonstration-imitation-case analysis-feedback and so on was established in the simulated family ward based on real objects and pictures. The training lasted for 5-7 days.After 12 months of observation, the changes of peritonitis and outlet infection cases, edema, blood pressure, outpatient follow-up compliance and laboratory examination indexes in the two groups were statistically analyzed.@*Results@#There were 5 cases of peritonitis, 2 cases of exit infection and 27 cases of edema in the experimental group, and 13 cases, 10 cases and 34 cases in the control group, respectively. The difference between the two groups was statistically significant (χ2=4.126, 5.847, Z=2.382, all P<0.05).The systolic blood pressure and diastolic blood pressure in the experimental group were (131± 13) and (86± 9) mmHg, respectively, and those in the control group were (140±15) and (92±11) mmHg, respectively. The differences between the two groups were statistically significant (t=2.789 and 2.595, all P<0.05). Compliance of outpatient follow-up was good in 33 cases in the experimental group and 27 cases in the control group, and the difference between the two groups was statistically significant (χ2=4.551, P<0.05).@*Conclusions@#The education and training of rural illiterate patients with peritoneal dialysis catheterization in simulated family wards has mobilized the patients' participation, improved their cognitive level, and improved their treatment compliance, thus effectively improving the patients' peritoneal dialysis effect and quality of life.

Methods Between January 2013 and December 2013 in our department, 80 patients with peritoneal dialysis catheter rural illiteracy as the research object, using the random number table method, the patients can be divided into the experimental group and control group, 40 cases of control group accepted traditional way standard training, the experimental group adopted simulation training family ward as the carrier, two groups of patients were carried out by the same pd specialist nurse training, the control group patients take traditional 7 days training courses for training, the experimental group according to the characteristics of the illiterate patients, an interactive learning mode of explanation-demonstration-imitation-case analysis-feedback and so on was established in the simulated family ward based on real objects and pictures. The training lasted for 5-7 days.After 12 months of observation, the changes of peritonitis and outlet infection cases, edema, blood pressure, outpatient follow-up compliance and laboratory examination indexes in the two groups were statistically analyzed. Results There were 5 cases of peritonitis, 2 cases of exit infection and 27 cases of edema in the experimental group, and 13 cases, 10 cases and 34 cases in the control group, respectively. The difference between the two groups was statistically significant (χ2=4.126, 5.847, Z =2.382, all P<0.05).The systolic blood pressure and diastolic blood pressure in the experimental group were (131± 13) and (86± 9) mmHg, respectively, and those in the control group were (140 ± 15) and (92 ± 11) mmHg, respectively. The differences between the two groups were statistically significant (t=2.789 and 2.595, all P<0.05). Compliance of outpatient follow-up was good in 33 cases in the experimental group and 27 cases in the control group, and the difference between the two groups was statistically significant (χ2=4.551, P<0.05). Conclusions The education and training of rural illiterate patients with peritoneal dialysis catheterization in simulated family wards has mobilized the patients' participation, improved their cognitive level, and improved their treatment compliance, thus effectively improving the patients' peritoneal dialysis effect and quality of life.
