BACKGROUND: The intelligence retardation in children refers to hypo-intelligence structure of full intelligence quotient(FIQ) composed of performance intelligence quotient(PIQ) and verbal intelligence quotient (VIQ) . It is verified in some researches that some of compound formulas provide better intervention on it.OBJECTIVE: To observe the effect of yizhi koufuye on intelligence structure in children with intelligence retardation.DESIGN: Homochronous controlled study based on children.SETTING: Pediatric department in a provincial college of traditional Chinese medicine and one provincial rehabilitation center.PARTICIPANTS: The cases were selected in Rehabilitative Central Hospital in Gansu Province and Clinic of the Hospital Affiliated to Gansu College of Traditional Chinese Medicine from January to July 2002. They were 74 students in Fudu Schools in Chenguan District, Lanzhou City, aged varied from 6 to 16 years, diagnosed as intelligence retardation according to CCMD-Ⅱ-R proposed Intelligence Retardation Diagnostic Standards, and they were able to accept medical and training treatment and were absent of congenital hereditary chromosome disorders. Of those, 47 cases were males and 27 cases females. They were divided into treatment group of 33 cases,the control of 20 cases and simple educational training group of 21 cases.METHODS: In treatment group of 33 cases, yizhi koufuye was administrated and was taken 15 mL each time for children younger than 10 years old, 20 mL for those between 10 to 14 years old and 25 mL for those over 14years old. In addition, the special educational training was applied. In the control of 20 cases, oral application of piracetam was prescribed, 0.4 g per time, 3 times a day and the special educational training was applied additionally. In simple educational training group of 21 cases, the children only received special education same as those in treatment group and the control. Three months made one session. Chinese-Wechsler Intelligence Scale for Children (C-WISC) and specific devices were used to assess FIQ and PIQ and VIQ in classified IQ in 3 groups before and after treatments, and the control comparisons were carried on among groups.MAIN OUTCOME MEASURES: Improvement of FIQ and improved values of VIQ and PIQ in 3 groups.RESULTS: Totally 74 cases were selected and no one lost. Improvement of FIQ: In treatment group, there were 44.7±9.8 and 51.8 ± 11.5 before and after treatment respectively, t = 2. 701, P ＜ 0.01; In the control, there were 43.8 ± 14.0 and 51.0 ± 13.6 before and after treatment respectively, t = 1. 680, P ＞ 0. 05; In simple educational training group, there were 41.6 ± 7.8 and 45.2 ± 10.6 before and after treatment respectively, t = 1. 561 and P ＞ 0.05. Improved values of VIQ: It was 8.1 ± 5.5 in treatment group, 5.3 ± 3.9 in the control and 4. 8 ± 4. 8 in simple educational training group. P ＜ 0.05 compared with the results in treatment group. Improved values of PIQ: It was 4.0 ± 3.6 in treatment group and P ＜ 0. 05 compared with 1.7± 2. 2 in the control and simple educational training group. Improving extent of VIQ was 8. 1 ± 5. 5 and of PIQ was 4.0 ± 3.6 in treatment group, P ＜ 0. 01.CONCLUSION: Yizhi koufuye improves markedly FIQ of children with intelligence retardation and for the classified IQ, the improving extent of VIQ is superior to that of PIQ.

Objective To analyze the pattern of normal bone marrow on whole body diffusionweighted imaging (WB-DWI) and its influence factors.MethodsA total of 98 healthy volunteers (male 47 and female 51). All volunteers underwent WB-DWI at 1.5 T MR scan. The ADC value,the signal intensity on DWI obtained with a b value of 800 s/mm2 ( SIDWI ),and the signal intensity on short time inversion recovery images ( SISTIR ) of thoracic vertebrae,lumber vertebrae,bilateral head of femur,bilateral neck of femur,bilateral superior segment of femur,bilateral inferior segment of femur,bilateral ilium,bilateral head of humerus,bilateral scapula were measured and compared with ANOVA test and StudentNewmar-Keuls test.The normal appearance of bone marrow on WB-DW[ was assessed. The relationship between the SIDwI and the ADC,and the SIDWI and the SISTIR of bone marrow were analyzed.The ADC of bone marrow between male and femaIe were compared. Spearman correlation analysis was performed for different age groups.Results( 1 ) Bone marrow signal intensity was different among 98 healthy volunteers.Bone marrow in 69 healthy volunteers (female 24,male 45 ) showed low to intermediate signal intensity,whereas in the remaining 29 healthy volunteers (female 27,male 2) showed high signal intensity.(2) The SIDWI of thoracic vertebrae ( median 44.54),lumber vertebrae ( median 35.01 ),head of femur ( median 13.61 ),neck of femur ( median 16.00),superior segment of femur ( median 21.45 ),ilium ( median 25.77),head of humerus (median 18.35),scapula (median 36.12) was positively correlated with the ADC [ (0.55 ±0.08) × l0-3,(0.53 ±0.08) × 10-3,(0.30 ± 0.10) × 10-3,(0.42 ± 0.16) × 10-3,(0.74±0.14) ×l0- 3,(0.49±0.10) ×10-3,(0.36±0.13) ×10-3,(0.49±0.11) × 10-3mm2/s]and the SISTIR ( median 61.81,64.99,53.27,69.08,73.10,66.35,73.16,79.81 ),r =0.513 and 0.695,0.741 and 0.764,0.443 and 0.489,0.641 and 0.656,0.510 and 0.648,0.475 and 0.715,0.366 and 0.446,0.437 and 0.739 ;P ＜ 0.01. (3) There was significant difference of the ADC of bone marrow in different bone,F =138.69,P ＜ 0.01. Student-Newman-Keuls test revealed that no significant difference was found in the ADC between thoracic vertebrae and lumbar vertebrae,ilium and scapula,head of humerus and inferior segment of femur ( P ＞ 0.05 ),and significant difference was found in the ADC values between the remaining two groups ( P ＜ 0.05 ). The bones associated with decreasing ADC values were superior segment of femur,thoracic vertebrae and lumber vertebrae,ilium and scapula,neck of femur,head of humerus,head of femur and inferior segment of femur. ( 4 ) The ADC values of bone marrow of female subjects in thoracic vertebrae [ (0.59 ±0.07) × 10-3 mm2/s],lumber vertebrae [ (0.58 ±0.06) × 10 -3 mm2/s],head of femur ( median 0.33 × 10 -3 mm2/s),neck of femur ( median 0.53 × 10 -3 mm2/s),superior segment of femur ( median 0.81 × 10-3 mm2/s),inferior segment of femur ( median 0.32 ×10-3 mm2/s),ilium [ (0.52 ± 0.09 ) × 10-3 mm2/s ],head of humerus (median 0.42 × 10-3 mm2/s),scapula [ (0.53 ± 0.09) × 10-3 mm2/s] were significantly higher than those of male subjects [ (0.51 ±0.07) × 10-3,(0.48 ±0.07) × 10-3,median 0.23 × 10-3,median 0.31 × 10-3,median 0.66 × 10-3,median 0.23 × 10-3,(0.46 ±0.10) × 10-3,median 0.27 × 10-3,(0.45 ±0.11 ) × 10 3mm2/s].(5)There was significant negative correlation between the ADC values of bone marrow and age in thoracic vertebrae,lumber vertebrae,head of femur,neck of femur,superior segment of femur,ilium,head of humerus for female subjects,r =-0.549, -0.629, -0.329, -0.524, -0.338, -0.548 and -0.416,respectively,P ＜ 0.05.There was no significant correlation between ADC values and age in inferior segment of femur and scapula for female subjects and all the regions for male subjects ( P ＞ 0.05 ).Conclusions The ADC and the SIsTIR of bone marrow correlates with the SIDW1.The ADC values of bone marrow is affected by age and sex,and is different for different bones.

ObjectiveTo observe the effect of botulinum toxin A (BTX-A) in rehabilitation training on cerebral palsy (CP).Methods47 CP children were randomly divided into the treatment group (32 cases) and control group (15 cases). Both groups were received rehabilitation training. But cases of the treatment group were injected with BTX-A in part of spastic muscles. Angles of inner contraction muscle (AICM) and activities of daily living (ADL) of two groups were observed for 6 months.ResultsImprovements of AICM and ADL in the treatment group were significantly better than that in the control group (P<0.01).Conclusions The rehabilitation training still is a kind of efficient treatment method. BTX-A injecting in part of spastic muscles is a kind of efficient assistant method and furnishes a better chance for rehabilitation training. Rehabilitation training combining with BTX-A injection can clearly curtail period of treatment, raise curative effect. BTX-A injection has significant applicable value in treatment on cerebral palsy.

OBJECTIVE To investigate the anti-inflammatory effects and mechanism of Zhuang medicine Tongfeng li’an capsules on gouty arthritis in combination with in vivo and in vitro experiments. METHODS Sixty rats were randomly divided into normal group， model group， positive control group （27 mg/kg allopurinol+0.27 mg/kg colchicine）， Tongfeng li’an capsules low- dose， medium-dose and high-dose groups （2.2， 4.5， 9.0 g/kg）， with 10 rats in each group. Except for normal group， gouty arthritis model of rats was induced in other groups. Rats in each administration group were given corresponding drugs intragastrically， and rats in the normal group and model group were given equal volume of water intragastrically for 14 consecutive days. The degree of ankle joint swelling， serum level of interleukin-1β （IL-1β） and protein expressions of nuclear factor kappa-B （NF-κB） in synovial tissue were detected， and the histopathological changes of synovium tissue in the ankle joint of rats were observed. The inflammation model was established by stimulating RAW264.7 cells with lipopolysaccharide. After Tongfeng li’an capsules （62.5， 125， 250 μg/mL） were given， the levels of nitric oxide （NO）， reactive oxygen species （ROS） and IL-1β in the cells and protein expression of NF-κB were detected， and NF-κB localization in the cells was also determined. RESULTS Results of in vivo experiment showed that compared with normal group， the swelling degree of the ankle joint， serum IL-1β level and protein expression of NF-κB in synovium tissue were all increased significantly in model group （P＜0.05）； pathological changes such as synovial hyperplasia， edema， vascular congestion， capillary hyperplasia， and increased inflammatory cells were observed. Compared with model group， the levels of above indexes were all decreased significantly in Tongfeng li’an capsules high-dose group （P＜0.05）， and most of the above indexes were significantly reduced in Tongfeng li’an capsules medium-dose and low-dose groups （P＜0.05）； synovial hyperplasia of the ankle joint improved， and the infiltration of inflammatory cells 2019BS044） decreased. Results of in vitro experiment showed that Tongfeng li’an capsule could significantly reduce the levels of NO， ROS and IL-1β and protein expression of NF-κB（P＜0.01）， and inhibit NF- κB nucleation. CONCLUSIONS Tongfeng li’ancapsules have good anti-inflammatory effect on gouty arthritis， and its mechanism may be related to the inhibition of NF-κB signaling pathway activity.
