Objective: To examine reliability and validity of Chinese Cognitive Ability Scale (CCAS).Methods:The CCAS was administered 321 children, 275 adults, 32 patients with brain damage, and 31 children with mental retardation.Out of them, 26 children were tested with WISC-CR and 26 adults with WAIS-RC.Results: The test-retest reliability coefficients of subtests and scales ranged from 0.732 to 0.894, 0.919 to 0.960 for children, 0.859 to 0.937, 0.968 to 0.981 for adults; The reliability coefficients for children (quick coding was omitted) ranged from 0.810-0.928 (Split-half), 0.737-0.923 (Cronbach's ?) and 0.737-0.945 (generalizability) for subtests, 0.939-0.976,0.898-0.965 and 0.898-0.965 for scales; Coefficients for adults ranged from 0.829-0.948, 0.747-0.941 and 0.747-0.941 for subtests, 0.945-0.979, 0.915-0.967 and 0.915-0.967 for scales; The CCAS IQs were high correlated with WAIS-RC IQs (VIQ=0.775,PIQ=0.621,FIQ=0.724) and WISC-CR IQs (VIQ=0.888,PIQ=0.779,FIQ=0.886) , the CCAS VIQ, PIQ, and FIQ were 5.3,9.2,and 7.8 points less than WAIS-RC, and 2.0,7.2,and 5.0 points less than WISC-CR; Comparing with normal groups, mean IQs of brain damaged adults(VIQ=80.50,PIQ=80.59,FIQ=78.91) and mental retardation children(VIQ=43.68,PIQ=49.77,FIQ=44.06)were much lower.Conclusion: The Chinese Cognitive Ability Scale has excellent retest stability, internal consistency reliability, convergent and discriminant validity.

Objective To study the characteristic of cognitive function impaired and its relationship with the psychiatric symptoms in patients with first-episode schizophrenia.Methods 43 first-episode male schizophrenia patients diagnosed with DSM-Ⅳ were recruited in the study and received the atypical antipsychotics treatment 8weeks.The total score and sub-scores of Chinese Cognitive Ability Scale (CCAS)were obtained for all the patients pre-and post-treatments,and the patients were also assessed by the Positive and Negative Syndrome Scale (PANSS).Results The differences of the intelligence quotient(IQ) and its cognitive function factors between pre-and post-treatment of the patients were significant(P＜ 0.01).The total IQ score (85.7 ± 11.5),learning ability (17.9± 2.3),reasoning ability (16.1 ± 3.4),processing speed (16.9 ± 2.1),working memory (13.8 ± 2.6),space/calculate (17.5 ± 2.9),verbal IQ (86.8 ± 11.7),performance IQ (83.9 ± 12.4) before treatment and cognitive score (97.6 ± 14.3) as well as cognitive function factor (learning ability (20.1 ± 2.9),reasoning ability (18.9± 3.1),processing speed (19.7 ± 1.8),working memory (15.7 ± 2.5),space/calculate (20.8 ± 2.5),verbal IQ (98.3 ± 13.7),performance IQ (95.8 ± 14.6) after treatment,there were significant differences pre-and posttreatment (P ＜ 0.01).The difference of IQ pre-and post-treatment was significantly correlated with that of total score and positive score of PANSS(r =0.596 or 0.783).Conclusions (1) This finding supports that the cognitive function impairment exists in the early stage of schizophrenia.(2)The typical antipsychotic drugs can improve the cognitive function impairment and psychiatric symptoms of schizophrenia.(3) The cognitive function impairment of schizophrenia has significant relation to the positive symptoms,but no relation to the negative symptoms.

Objective To explore the curative effect of insulin combined with An Er Shu in treatment ofⅡtoⅢ degree pressure sores of elderly patients with diabetes mellitus. Methods A total of 120 cases of elderly diabetes mellitus patients with Ⅱ to Ⅲ degree pressure sores were randomly divided into the control group (30 cases, conventional nursing treatment), the experimental group 1 (30 cases, insulin spray coating), the experimental group 2 (30 cases, An Er Shu brushing besmear), and the experimental group 3(30 cases, insulin combined An Er Shu). The curative effect and the healing time were observed. Results After four weeks treatment total effective rate was 60.0%(18/30) in the control group, 66.7%(20/30) in the experimental group 1, 76.7%(23/30) in the experimental group 2, 100.0%(30/30) in the experimental group 3, and there was significant difference in the 3 experimental groups comparing with the control group, the experimental group 1 and the experimental group 2, respectively (χ2=15.000, 12.000, 5.822, P<0.05 or 0.01). The healing time ofⅡdegree pressure sores was (19.03 ± 0.85) d in the control group, (18.90 ± 0.92) d in the experimental group 1, (18.43 ± 0.82) d in the experimental group 2, and (16.97 ± 1.25) d in the experimental group 3, and there was significant difference in the experimental group 3 comparing with the control group, experimental group 1 and experimental group 2, respectively (t=8.013, 7.918, 8.930, P<0.01), and in the experimental group 2 comparing with the control group (t=3.525, P<0.01). The healing time ofⅢdegree pressure sores was (24.17 ± 1.51) d in the control group, (23.63 ± 1.33) d in the experimental group 1, (23.47 ± 1.25) d in the experimental group 2, and (21.07 ± 1.46) d in the experimental group 3, and there was significant difference in the experimental group 3 comparing with the control group, experimental group 1 and experimental group 2, respectively (t=6.918, 7.048, 9.200, P<0.01). Pressure sores area reduction was (44.47 ± 37.63)%in the control group, (56.50 ± 39.64)%in the experimental group 1, (66.23 ± 37.54)%in the experimental group 2, and (96.52 ± 7.71) % in the experimental group 3, and there was significant difference in the experimental group 3 comparing with the control group, the experimental group 1 and the experimental group 2, respectively (Z=-4.274,-4.274,-3.400, P<0.01). Conclusions Insulin combined An Er Shu in treatment of pressure sores in elderly patients with diabetes mellitus can improve curative effect and shorten the healing time.

Objective To explore the relationship between infant feeding practices and infants growth,especially the weight gain for length in the first 6 months of life. Methods Two-hundred healthy full-term singlet normal birth weight 5 - 6 months old infants and their main care givers were recruited in Kongjiang community health service center in Shanghai. The questionnaires included infants feeding pattern, feeding environment and care givers feeding behaviors, and were completed on-site by investigators. The birth weight was obtained. The weight and length of infants at 6 months were measured. Results There were 70/200 (35.0%) infants overweight (BMI for age Z score>+1) at 6 months. There were more overweight boys than girls (40.0% vs. 30.9%, x2 = 1.798, P = 0.180). Compared with normal weight infants, the overweight infants had same birth weight (3.30 ± 0.35 kg vs. 3.35 ± 0.32 kg, t =1.010, P = 0.314) and same length at 6 months (67.64 ± 2.10 cm vs. 67.91 ± 1.97 cm, t=- 0.896, P = 0.371). However, the overweight infants gained much more weight for length in the first six months of life. At 6 months, the weight and BMI of overweight infants was significantly higher than that of normal weight infants (9.16 ± 0.67 vs. 7.94 ±0.64, t = 12.324, P < 0.01;19.86 ± 1.24 vs. 17.41 ± 0.80, t = 14.953, P < 0.01). The rates of exclusive breastfeeding for at least four months, continued breastfeeding at six months, complementary food consistency, and complementary feeding frequency, were not significantly differenct between overweight and normal weight infants (x2 =0.723 - 2.701, P > 0.05). The grandparents played an important role in infants feeding in Shanghai. There were 39.0% infants fed only by grandparents, and 23.0% infants fed jointly by grandparents and parents (x2 = 0.175, P > 0.05).The care givers' educational level and knowledge of feeding skill were similar in overweight and normal weight infants (x2 = 0.446, t = 0.949, P > 0.05). However, the overweight infants were fed more quickly than normal weight infants (Z = 2.753, P < 0.01), and there was less language communication between care givers and overweight infants during feeding (Z = 2.932, P < 0.01). In overweight infants, the overfeeding behaviors of care givers were positively correlated with BAZ (r = 0.281, P < 0.05). Conclusions Overweight in early life is associated with some particular infants feeding behaviors of care givers in Shanghai. The long term effect of more rapid weight gain for length in the first 6 months of life on the risk of childhood obesity warranted to be further followed and researched.

Objective To discuss the polymorphisms of asthma susceptibility gene ORMDL3 in infantile wheezing,in order to provide a theoretical basis for early diagnosis of asthma.Methods One hundred and fifty wheezing infants were recruited and divided into 2 groups as asthma predictive index(API) positive group(n =80) and negative group (n =70).Taqman probe was applied to detect the genotypes of 2 single nucleotide polymorphisms (SNPs)in childhood asthma susceptibility gene ORMDL3,which were rs4794820 and rs7216389.The genotype distributions were analyzed and compared between 2 groups,and the correlations among genotype distribution and tidal breath pulmonary function,fractional exhaled nitric oxide (FeNO) concentration,percentage of eosinophils (EOS％),serum immune globulin E (total IgE) levels respectively were also analyzed,respectively.Results (1) The frequencies of rs4794820 AG and rs7216389 TC heterozygotes in the API positive group were the highest,which were significantly higher than those in the negative group(58.75％ vs.31.42％,56.25％ vs.32.86％ respectively,all P ＜0.01).The frequencies of GG and TT homozygotes in the API negative group were the highest,which were significantly higher than those in the positive group (58.57％ vs.30.00％,57.14％ vs.31.25％ respectively,all P ＜0.01).(2)The time to reach the peak expiratory flow in tidal breathing over the total expiratory time (TPTEF/TE) and the volume to reach the peak expiratory flow in tidal breathing over the total expiratory volume (VPEF/VE) of the infants in the API positive group were less than those in the API negative group(16.87 ±5.31 vs.20.12 ± 5.23,20.87 ± 5.92 vs.25.56 ± 6.77,respectively),and the FeNO concentration was higher than that in the API negative group [(22.44 ± 9.77) ppb vs.(13.23 ± 7.90)ppb],and the differences were significant (t =-3.776,-4.490,6.377,respectively;all P ＜ 0.01).(3) In the API positive group,the TPTEF/TE and VPEF/VE of the infants who expressed AG/TC genotype were lower than those who expressed GG/TT genotype (14.55 ± 4.83 vs.19.91 ± 4.17,18.85 ± 4.26 vs.25.20 ± 7.06,respectively,t =-4.727,-3.976,all P ＜ 0.01);while the FeNO concentrations,EOS％ and total IgE levels were higher than those who expressed GG/TT genotype [(25.02 ± 8.77) ppb vs.(18.39 ± 6.56) ppb,7.16 ± 2.62 vs.5.50 ± 1.34,(366 727 ±275 533) IU/L vs.(166 826 ± 62 865) IU/L,respectively] (t =3.484,3.409,4.589 respectively;all P ＜ 0.01).Conclusions Childhood asthma susceptibility gene ORMDL3 SNPs rs4794820 AG and rs7216389 TC heterozygotes are the risk factors for API positive infantile wheezing.The pulmonary function damage and airway inflammation of the infants who expressed AG/TC genotype are more serious than those who expressed GG/TT genotype,and more likely to develop persistent asthma.

Objective To observe the effects of functional ambulation training in a realistic environment based on the activities of daily living among stroke patients with hemiplegia.Methods Thirty-two stroke survivors with hemiplegia were randomly divided into an experimental group and a control group,each of 16.Both groups were given routine rehabilitation training,while the experimental group was additionally given functional ambulation training based on the activities of daily living in a realistic environment for 60 min per day,five days a week for six weeks.Both groups were evaluated using the mini-mental state examination (MMSE),the Holden walking functional class assessment (HWFCA),the Berg balance scale (BBS),functional gait assessment (FGA),the 5 times sit to stand test (FTSST),the timed up and go test (TUGT),and rated using the specific activity balance confidence scale (ABC) and the modified Barthel index (MBI).Results Before the training,no significant differences between the two groups were found in terms of any of the measurements.After the six weeks of training,significant improvement was observed in all of the outcome measures except the MMSE and the HWFCA,with the experimental group scoring significantly better,on average,than the control group.Conclusion When combined with routine rehabilitation training,functional ambulation training based on the activities of daily living in a realistic environment can significantly enhance the functional gait,balance and postural control of stroke survivors.This should facilitate their activities in daily life and improve their confidence in maintaining their balance.
