Visual perceptual learning refers to the special improvement of perceptual performance benefit from repetitive training with a visual task.A typical time course of visual perceptual learning presents an initial rapid improvement,and then gradually processes like an asymptote in gain.During the process of perceptual learning,the influence of critical amount and perceptual learning rules on learning effect,memory consolidation and interference,and the role of sleep on preventing interference and promoting consolidation in perceptual learning,all get involved.This article reviewed the aforesaid content and then elaborated some strategies in application of visual perceptual learning in the treatment of amblyopia.

Objective To investigate the relationships between seven single nucleotide pdymorphisms(SNPs), including 6788895(SIAH2 gene), rs10941679(5p12), rs889312(MAP3K1), rs13387042(2q35), rs6504950(17q23), rs17530068(6q14) and rs2284378(20q11), and female breast cancer of Hui and Han nationalities.Methods A hospital-based case-control using age and nationallity as frequency matching conditions was conducted in Affiliated General Hospital of Ningxia Medical University.Results ①A total of 225 breast cancer patients and 225 controls were enrolled in this study.There was no significant differentce between case group and control group in age(48.27±9.27 vs 48.48±9.36, t=0.238,P=0.812) or nationallity (181 Han people and 44 Hui people vs 184 Han people and 41 Hui people, x2=0.131, P=0.718).②The subjects of study conformed to Hardy-Weinberg equilibrium principles.③The genotype and allele distribution of the above seven SNPs were not significantly different between cases group and control group of Hui and Han nationalities.Conclusion The seven SNPs mentioned above may not be related to breast cancer among people Hui and Han nationalities.

Objective To explore the efficacy of tepronone and folic acid in the treatment of chronic atrophic gastritis (CAG) evaluated by the marking targeting biopsy (MTB).Methods A total of 224 H.pylori negative CAG patients were selected and divided into group A (n 96,tepronone 50 mg/time,folic acid 10 mg/time,three times/day),group B (n=23,tepronone 50 mg/time,three times/day),group C (n=74,unspecific treatment) and group D (n=31,no treatment).The treatment course lasted for one year.The clinical symptoms improvement of each group was observed before and after treatment.The pathological improvement of gastric mucosa by MTB was inspected before and after treatment.The chi square test was performed for the comparison between groups.Results The total efficacy rates of group A,B,C and D were 43.8％ (42/96),39.1％ (9/23),33.8％(25/74) and 32.3％ (10/31) respectively,there was no significant difference between groups (x2 =2.328,P =0.507).For the significant efficacy rate of gastric mucosa pathological improvement,group A was compared with group D,group A was compared with group C and group B was comparedwith group D,the differences were significant (x2 =14.520,14.628 and 8.995,all P＜0.01).In the total efficacy rate of gastric mucosa pathological improvement,group A (49.8％,131/263) was compared with group D (24.2％,16/66),group A was compared with group C (35.9％,66/184)and group B (44.7％,21/47) was compared with group D,the differences were significant (x2 =13.953,8.535 and 5.207,all P＜0.05).Conclusion Teprenone alone or teprenone and folic acid combination can obviously improve pathological changes of CAG patients.

Objective To investigate the correlation between depression, anxiety and sleep disturbance. Methods 93 patients with the main complaint of insomnia were selected and performed a retrospective study. Results Four factors including anxiety factors, manifest anxiety, subjective depression and dominant depression of the insomnia patients were significantly higher than normal people, while the Ego Strength scores are significantly lower than the normal people. Conclusion When confronting patients with sleep disturbance, doctors must pay attention to identifying any psychological disorders including depression and anxiety in the patients, and psychological support should also be strengthened to such patients.

ObjectiveTo study the effect of thought imprint psychotherapy in lower resistant state (a TCM psychotherapy ) treating insomnia accompanied by depression.MethodsIntervened patients by sleep regulating technique of lower resistant state for 6 months.PSQI and PSG were tested prior and post treatment.ResultsThe data from PSQI and PSG indicated the improvement of their sleep quality:PSQI:sleep quality (2.500±0.589) vs (1.416±0.928),initiating sleep time(2.375±0.875) vs (1.416±0.880),sleep time (2.125±0.947) vs (1.500±0.884),sleep efficiency (1.625±1.135) vs (0.958±0.954),sleep disorder (1.875±0.536)vs (1.416±0.775),daytime function (2.416±0.880) vs (1.833± 1.203); PSG:sleep efficiency (0.82±0.11)％ vs (0.88±0.10)％,number of wake (3.92±3.24) vs (2.38±1.21),stage 1 percentage (27.4±11.9)％vs (23.5±7.8)％,stage 3 percentage (10.2±6.8) ％ vs (15.6±5.9)％,REM sleep percentage (23.89±6.84) ％ vs (16.16 ± 6.36) ％,P＜0.05 or 0.01.ConclusionSleep regulating technique in lower resistant state can improve patients' sleep quality.

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

AIM To establish an HPLC method for the simultaneous content determination of huperzine A and huperzine B from seventeen species Huperzioideae subfamily (including 2 ineditus new species).METHODS The analysises of tartaricacid extracts of huperzine A and huperzine B were performed on a room temperature column (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of methanol-spiritus mindereri flowing at 1.0 mL/min in a isocratic elution manner,and the detection wavelength was set at 310 nm.The contents were determined by external standards.RESULTS Huperzine A and huperzine B showed good linear relationships within 0.002 0-0.30 μg,0.001 8-0.27 μg (r=0.999 9),whose average recoveries were 103.86％,101.3％ with the RSDs of 1.85％,1.30％,respectively.Huperzine A and huperzine B were found in seventeen species,and there were significant differences in contents from species to species.The content of huperzine A in Phlegmariurus hamiltonii was the highest,which reached up to 0.22％,with higher levels of it in Phlegmariurus cryptomerianus,Phlegmariurus petiolatus,and Phlegmariurus phlegmaria;The content of huperzine B was the highest in P.phlegmaria.CONCLUSION This accurate,stable and reproducible method can be used for the quality control of huperzine A and B from Huperzioideae subfamily.
