Objective To characterize the language development and articulation in children with different types of cerebral palsy. Methods The data from 76 children with cerebral palsy who underwent standardized tests of speech and language were analyzed. The incidence and abnormal pattern were compared between groups. ResultsLanguage delay and/or dysarthria were noted in 73.1% of these subjects. Children with diplegia developed similar levels both in comprehension and verbal expression, whereas those with tetraplegia and athetoid developed poorer verbal expression. The incidence of language delay in children with diplegia, tetraplegia and athetoid were 45.95%, 90% and 64.7%, respectively. Dysarthria was found in all the children with tetraplegia, athetoid and ataxia, but only 48.65% of those with diplegia. Conclusion Language disorders were common in children with cerebral palsy, especially those with athetoid and tetraplegia.

AIM: To investigate the effect of Ganoderma lucidum spores powder on the expression of insulin-like growth factor-1 (IGF-1), nuclear factor-?B (NF-?B) and apoptosis of nerve cells in rats with epilepsy established by pentetrazole. METHODS: The sub-eclampsia dosage of pentetrazole (PTZ) was used to make epilepsy model. Ganoderma lucidum spores powder group was given from stomach. The enduring time and latent period were recorded. The immune reactivity of IGF-1, NF-?B/P65 and apoptosis of nerve cells were measured with immunohistochemical staining and TUNEL method. RESULTS: In high power sight (?400), there were much more apoptosis cells in hippocampus and brain cortex of model group (18.80?2.13, 16.87?2.00) than those in control group (0.97?0.52, 0.58?0.25). The expressions of IGF-1, NF-?B in model group were higher than those in control group. Compared with model group, the latent period of Ganoderma lucidum spores powder group at the 17th, 21th, 25th days were longer (P

Objective: To observe blood-activating and stasis-resolving therapy (活血化瘀法)for patients with acute hypertensive cerebral hemorrhage small and moderate in amount and its influence on patients daily ability. Methods: One hundred and twenty-four cases were randomly divided into 3 groups: A group (n=52 cases), B group (n=34) and C group (n=38). Besides conventional therapies, A and B groups were treated additionally with 20 ml of Danshen injection (丹参注射液) in 5% glucose solution 250 ml for intravenous drip (once a day), 28 days constituting one therapeutic course, the beginning of the injection in A group was 24-48 hours after the attack and that of B group, 1 week after the attack. All the cases were evaluated by effective rate, neural defect score (NDS), ability of daily life (ADL), modified Barthel index (MBI), the duration for the absorption of intracranial hematoma, mortality, etc. The therapeutic effects of the 3 groups were compared after the treatment for 28 days, 3 months and 6 months. Results: The total significant effective rates in A group and B group were significantly better than that of C group (all P0.05). Conclusion: The early use of blood-activating and stasis-resolving therapy is effective for patients with acute hypertensive cerebral hemorrhage small and moderate in amount, it may promote the absorption of the intracranial hematoma, and improve the patients′ remote prognosis.

OBJECTIVETo explore the mischief mechanism of oxidative stress in the varicocele (VC).

METHODSSerum was taken from the spermatic and peripheral veins on ligation of the internal spermatic veins in 28 infertile males with VC. Experimental VC was established in male rats by partial ligation of the left renal vein. And testis tissue was taken three months after operation. The nitric oxide(NO), nitric oxide synthetase (NOS), xanthine oxidase (XO), lactic acid(Lac) and lactic dehydrogenase (LDH) in the serum of 28 infertile males with VC and the testis tissue of the VC rats were detected by spectrophotometry.

RESULTSNO, NOS, XO and Lac in the serum of internal spermatic veins in the infertile males with VC were significantly higher than in the serum of peripheral veins in the VC patients (P < 0.01, P < 0.05). LDH was lower than that in peripheral serum. NO and XO of the left testis tissue in the VC rats were higher compared with the control group (P < 0.01). Lac in the left testis of the VC rats was lower than that in the control group rats (P < 0.01).

CONCLUSIONNO, NOS and XO in the serum of the VC patients and in the testis tissues of the VC rats were increased, and Lac and LDH were changed obviously, which might not only disturb spermatogenesis, but also inhibit sperm motility. Therefore they might be one of the causes of infertility in VC patients.

According to the general goal of long term development of basic science from 2021 to 2035 and the "14th Five-Year Plan" in China, starting from the reasearch characteristics and the basic situation of endemiology, this study discusses the strategic position, development law, development trend, development status and layout, development goals and realization ways of endemiology, combined with the strategic needs of the discipline, the important interdisciplinary research areas of endemiology are put forward. The purpose of this study is to promote the rapid development of basic research on endemic diseases, to provide reference for the scientific and technological layout and policy formulation of the endemiology, to provide reference for the "14th Five-Year Plan" in China, and to provide guarantee for the people in the sick area to seek health.

Based on the general goal of the medium and long term development of basic science from 2021 to 2035 and the "14th Five-Year Plan" in China, combined with the national strategic needs, this paper discusses the five priority development areas of endemiology according to the development trends and characteristics of endemiology in the next 5 - 15 years. The five areas are study on the pathogenesis and prevention measures of endemic fluorosis; study on risk assessment, pathogenic mechanism and control strategy of environmental arsenic exposure; research on the basis and application transformation of the pathogenesis of iodine nutrition-related diseases; molecular mechanism and targeted intervention of cartilage injury in Kashin-Beck disease; precise prevention and treatment, preservation of biological samples and etiology study of Keshan disease. Combined with the scientific significance and national strategic needs of various field, the authors analyze its main study directions and core scientific issues.
