ObjectiveTo investigate the intelligence characteristics and relativity with motor development of children with spastic diplegia.MethodsIntelligence and motor development of 46 children with spastic diplegia were tested by Wechsler Intelligence Scale and Motor Development Milestone (MDM), to find out difference of intelligence between the children with diplegia and the normal control group.ResultsIntelligence quotient (IQ) of children with spastic diplegia was lower significantly than the normal control, specially performance IQ (PIQ). PIQ was related with motor development. The more delayed motor development was, the more lower PIQ was. Subtest scores of animal egg, puzzle, block design and picture generalization were lower in spastic diplegic children with normal IQ than that of the normal control group, while vocabulary IQ (VIQ) was not different.ConclusionThe intelligence structure of children with spastic diplegia is imbalanced and PIQ of those children is significantly lower than the normal children, which is related to hands-eyes correspond, sight-motor correspond and speed, and space-sight ability.

Objective To investigate the value of intraoperative ultrasound in the resection of hemangioblastoma.Methods Intraoperative ultrasound was applied in 17 patients who underwent resection. The size,number,location ,depth,feeding arteries and draining veins of the tumors were clearly displayed.Results Intraoperative ultrasound could real-time locate the tumor with high accuracy. Totally there were 35 tumors in 17 patients, and intraoperative ultrasound found 32 of them.The diameter of thr smallest tumor was 7 mm. Intraoperative ultrasound could displayed clearly the feeding arteries and draining veins in bigger tumors. Conclusions Intraoperative ultrasound should be routinely used in the operation of hemangioblastoma for its high detection rate.

AIM: To investigate the effect of Z,E-butylidedephthalide (Bdph) on laser-induced experimental choroidal neovascularization (CNV) in rat model and choroid blood flow in rabbits'eyes.METHODS: Male Brown Norway rats were treated with Nd:YAG laser to break Bruch's membrane. Thirty mg/kg and 15 mg/kg Bdph were given daily through intraperitoneal injection for 4 weeks after laser treatment. Fluorescein angiography (FA) and choroidal flat mount were used to measure the development of CNV. Female New Zealand white rabbits' eyes were instilled with 10g/L Z,E-butylidenephthalide solution,and ocular blood flow was measured with colored microsphere technique. RESULTS: The intensity of fluorescein leakage, indicating the ocular lesion, decreased significantly in group Bdph 30mg/kg and 15mg/kg, as compared to the control at P＜0.01.The area of neovascularization checked by FA in both groups of Bdph, at 30mg/kg and 15mg/kg decreased significantly compared to the control group at P＜0.05. On the choroid flat mount, the areas of CNV were also smaller in both Bdph groups than in control group. One percent Z,E-butylidenephthalide solution instilled into rabbits' eyes could improve the choroid blood flow at 30 and 60 minutes after drug instillation (P＜0.05).CONCLUSION: Z,E-butylidedephthalide could inhibit the development of CNV in the rat eyes and increase the choroid blood flow in the rabbit eyes. These results suggest that Z,E-butylidedephthalide may be a good agent for the treatment of age-related macular degeneration(ARMD).

Objective By comparing the organ system based medical integration teaching mode and traditional teaching mode to evaluate the effect of the integration of curriculum implemen-tation. Methods Through a questionnaire survey of 63 students who implement integrated curriculum and 183 students who are not implementing integrated curriculum as well as 76 teachers, we evaluate students' emotional, cognitive and motor skills, using SPSS statistical analysis, chi-square test. Results In the affective domain, most of the teachers thought the experimental class was superior to the com-mon one in learning interest, lifelong learning and independent learning, critical thinking, the contrast of the two classes were P=0.000, P=0.031 and P=0.001 respectively, all of significant difference. In the cognitive domain, the contrast of the two classes in memory, understanding and application were P=0.000, all of significant difference. The experimental class has high degree of recognition. In the psychomotor domain, more than 55.3%(42/76) of the teachers thought that the experimental class was superior to the common class. According to the students' questionnaire survey, the contrast of the two classes in clinical operation skills, Interpersonal communication skills were P=0.077, P=0.031 respec-tively. There was no statistically significant difference. Conclusions The integrated curriculum teach-ing model can greatly promote students' abilities in most areas such as interest in learning, lifelong learning awareness, clinical thinking ability; interpersonal communication skills etc. In some respects the differences remains to be further studied such as memory of knowledge, systematic knowledge, and clinical operation skills, etc.

Objective To explore the pulse diagram parameter changes of chronic renal insufficiency patients with five symptoms types(spleen kidney qi deficiency ,spleen kidney Yang deficiency ,kidney liver Yin deficiency and the deficiency of Yin and Yang ) , and to establish the differentiation mode of each symptoms type for assisting the clinical diagnosis .Methods The DS01-C pulse manifestation instrument made by the Shanghai Daosh company was adopted to detect and analyze the pulse manifestations in the healthy control group and the chronic renal insufficiency group .Results The healthy control group was dominated by the normal pulse manifestation .The chronic renal insufficiency group was dominated by the taut pulse and its concurrent pulse .Along with the progress of the disease ,the pulse manifestations also appeared the corresponding changes .The patients with spleen kidney qi defi-ciency and spleen kidney Yang deficiency were dominated by the taut pulse .Comparing the patients with liver kidney Yin deficiency and Qi Yin deficiency ,the taut pulse and concurrent rapid pulse were common ,in addition ,the former also had the deep pulse .The patients with Yin and Yang deficiency showed the slow pulse and the taut pulse or the taut pulse and rapid pulse .Conclusion The pulse manifestation change in the patients with chronic renal insufficiency is dominated by the taut pulse and the concurrent pulse , the pulse manifestation change of various symptoms types are complex .

To study the immunopathological characteristics and differential diagnosis of hepatic angiomyolipoma(AML).Methods:Thirty-six surgically resected hepatic AML were investigated clinicopathologically and immunohistochemically with 10 antibodies.Results:Hepatic AML occurred in 21 females and 15 males,with the mean age of 41.6 years(26-60 years old).The patients with AML often had no special symptoms even had large space-occupying lesions in the liver.The diameter of AML was 2.5 cm to 14 cm(mean 6.8 cm).Histologically,AML was composed of varying heterogeneous mixture of 3 tissue components:blood vessels,smooth muscle and adipose cells.Extramedullary hemopoiesis sometimes existed.According to tissue components,AML was subcategorized into mixed type(19.4%,n=7),lipomatous type(11.1%,n=4),myomatous type(66.7%,n=24),and angiomatous type(2.8%,n=1).The epithelioid smooth muscle cells were sensitive to HMB-45(100%),SMA(100%),and CD117(66.7%) staining.Conclusion:Hepatic AML often contains smooth muscle elements,which have varied morphological features and should be carefully differentiated from hepatocellular carcinoma,mesenchymal hamartoma，and tumors with rich fat or blood vessels.Immunohistochemical staining with HMB-45 and SMA are the best available markers for the diagnosis of hepatic AML.

Objective: To analyze the epidemiological characteristics of influenza clusters in Hangzhou from 2018 to 2019, so as to provide references for the prevention and control of influenza. Methods: The data came from the epidemic investigation reports of influenza clusters in Hangzhou from the 27th week of 2018 and the 26th week of 2019. The time distribution, school types, population distribution and etiology of influenza were analyzed. Multivariate logistic regression model was employed to analyze the influencing factors for the attack rate of influenza clusters. Results: During the surveillance season, a total of 231 school influenza clusters involving 4 233 cases were reported. The median of the attack rate was 21.74%. The peak of the clusters was in March 2019, with 89 events and 1 476 cases ( 34.87% ). The clusters occurred mainly in primary schools ( 188 events, 81.39% ) and were mainly caused by Victoria-like strains of influenza B virus ( 84 events, 36.36% ). The multivariate logistic regression analysis indicated that infection of teachers increased the risk of high attack rate ( OR=3.133, 95%CI: 1.180-8.320 ), and kindergartens had higher risk of high attack rate than primary schools ( OR=4.123, 95%CI: 1.579-10.763 ). Conclusions The influenza clusters in Hangzhou from 2018 to 2019 is mainly caused by Victoria-like strains of influenza B virus. Kindergartens and teachers are the key points for the prevention and control of influenza clusters.
