Objective:To study the behavior problems in children with Tourette syndrome and related family factors.Methods:132 children with Tourette syndrome were collected as our sample. Their parents completed CBCL (child behavior checklist) and FES (family environment scale).Results:The rate of behavior problems in this group was 26.5%, much higher than that of normal children (13.6%). The main factors having influence on this included expressiveness, independence and initiative, entertainment and moral religion. The Wald of the four factors in Logistic regression were 13.73, 10.35, 7.97 and 5.62(P

Objective To explore the clinical value of wave intensity (WI) in evaluating early changes of cardiovascular function in patients with type 2 diabetes mellitus (T2DM).Methods Thirty T2DM patients without atherosclerosis by conventional ultrasonography were enrolled as case group,while thirty healthy volunteers were enrolled as control group.Two groups were well-matched in age and sex.Both of the case and control groups were taken WI test of carotid artery.The parameters of WI examinations in two groups were measured and compared.Results Compared to the control group,values of arterial stiffness index (β),elasticity modulus (Ep),pulse wave transit velocity (PWVβ),and decelerating wave intensity (W2) were significantly higher in T2DM group (P ＜0.05).Arterial compliance (AC) value was significantly reduced in T2DM group (P ＜0.05).Accelerating wave intensity (W1) value was higher in T2DM group without significant statistical differences (P ＞ 0.05).Conclusions WI technique which can early assess the changes of left ventricular function and vascular elasticity in T2DM patients has important clinical value.

Objective To investigate the effect of N-nitro-L-arginine (NO2Arg) on the development of morphine tolerance and dependence.Methods Forty male SD rats weighing (180 ? 18)g were randomly divided into 5 groups for the study of morphine physical dependence and tolerance : group Ⅰ normal saline; group Ⅱ morphine; group Ⅲ morphine + 1 mg?kg-1 NO2Arg; group Ⅳ morphine + 5 mg?kg-1 NO2 Arg ; group Ⅴ morphine +20 mg?kg-1 NO2Arg. Twenty-four male Kunming mice weighing (20.0 ? 2.3)g were randomly divided into 3 groups for the study of psychological dependence: group Ⅵ morphine; group Ⅶ dihydro etorphine; group Ⅷ normal saline. The morphine physical dependence was induced by dose increment. The degree of morphine tolerance was assessed by the pain threshold to heat radiation using tail-flick test. The degree of morphine physical dependence was determined by evaluating the abstinence syndrome precipitated by 4 mg?kg -1 naloxone. The psychological dependence of mice was evaluated by conditioned place preference. Results Consecutive injection of NO2Arg inhibited the development of morphine tolerance in a dose-dependent manner. 5 mg?kg-1 NO2 Arg suppressed most abstinent symptoms of morphine dependent rats. The duration when morphine and dihydro etorphine psychologically dependent mice stayed in the preferred compartment increased significantly from (6.1? 2.0)min and (8.0?0.7)min to (9.3?1. l)min and (9.5 ? 1.2) min by 4 mg?kg-1 NO2 Arg. Conclusion NO2 Arg can inhibit the development of morphine tolerance and dependence and reverse the existing psychological dependence.

ObjectiveTo study the effect of rehabilitation treatment on diffuse axonal injury(DAI).Methods24 inpatients with DAI were performed a 3 month rehabilitation program.Before and after rehabilitation treatment,evaluation of locomotion function, walking ability,activities of daily living(ADL) and cognitive ability were performed and compared with each other.ResultsThe hand function showed no distinct change(P>0.05), while the locomotion function of upper limb was improved significantly(P<0.05), and that of lower limb was improved more significantly (P<0.01) as while as the walking ability.ADL and cognitive ability were improved very more significantly (P<0.001).ConclusionsIntegrative rehabilitation treatment cannot significantly improve the hand function of patients with DAI, but can significantly improve the locomotion function of upper and lower limb,ADL and cognitive ability.

BACKGROUND: Hemiplegia caused by stroke or brain injury may lead to secondary osteoporosis. Under the circumstance, bone mineral density (BMD) and Bone Mineral Content (BMC) are two effective factors for predicting the risk of osteoporosis-related fracture OBJECTIVE: To investigate the characteristics of secondary osteoporosis in stroke patients with hemiplegia by measuring and analyzing BMD and BMC.DESIGN: A case study.PARTICIPANTS: From March 1999 to May 2002, 156 hemiplegia patients at the Neurorehabilitation Department of Peking Boai Hospital were selected, 87 males and 69 females, with an age ranging from 17 to 65 years old, in average of (47.0±5.3) years old and having a course of diseases ranging (5.0±3.5) months. The types of their illness: 89 had cerebral infarction, 67 had cerebral hemorrhage. Hemiplegia sides: 79 patients had hemiplegia in the left and 77 in the right.METHODS: Using LUNAR Dual Energy X-Ray densitometers, all the patients underwent a fro-top-to-toe scan to assess the BMD and BMC status.MAIN OUTCOME MEASURES: ① The occurrence rate of osteoporosis in patients with various course of hemiplegia. ② The BMC in patients with hemiplegia in various part.RESULTS: All the 156 patients entered the statistical analysis procedure.① The occurrence rate of osteoporosis was highest in patients with 3 to 6 months of hemiplegia (44%, 16/36) and was lowest in those with 9 to 12 months of disease (21%,7/33). The total occurrence rate of osteoporosis was 31% (48/156). ② For those with a less-than-3-month course of hemiplegia: Of all the 47 patients, 9 had dystonic hemiplegia, all suffering from osteoporosis and 2 of whom having fracture. For those with a 3-to-6-month course of hemiplegia: Of all the 36 patients, 3 had dystonic hemiplegia and osteporosis as well. ③ BMC in the affect side of upper limb was signifi cantly lower than that in healthy side [(154.76±43.91) g, (172.59±43.78) g,t=3.591, P＜ 0.001]. BMC in the affect side of lower extremity was close to that in healthy side [(463.41±30928) g, (464.11±86.45) g, t=0.027, P＞ 0.05].CONCLUSION: In patients with hemiplegia, changes in bone mass fluctuate with the length of hemiplegia. BMC in the affect side of upper limb is low while that in the healthy side is nearly normal. It may be explained that upper extremities start the functional exercises at an early time. This indicated that bone mass has a close relationship with excercises.

Objective To characterize the secondary osteoporosis in hemiplegic patients. Methods By use of dual energy X ray absorptometry, the bone density and bone mineral quantity of 156 hemiplegic inpatients were tested and analyzed. Results The incidence of osteoporosis was 44.4% during 3～6 months after stroke and 21.1% found during 9～12 months after stroke. The average incidence was 30.8%. The osteoporosis was more common in patients with flaccid hemiplegia than in those with spastic hemiplegia. The bone mineral quantity in the affected upper limbs was significantly lower than that in nonaffected side ( P 0.05). Conclusion The bone mineral quantity of hemiplegic patients varies with the duration of disease. The reduction of bone mineral quantity is regular and reversible.

Objective To explore the role of Kupffer cells( KCs)disorder on the occurrence and development of Nonalcoholic Fatty Liver Disease ( NAFLD) by means of rat model fed with high-fat diet. Methods Twenty-four male SD rats were random divided into model group ( n =12) and normal group( n = 12) , with a high-fat diet and standard diet for 12 weeks. The levels of body weight, liver weight, alanine aminotransferase( ALT), aspartate aminotransferase( AST) , triglyceride(TG) , and total cholesterol( TC) were measured. Routine histological features of hepatic section were observed by H. E staining. The shape changes of KCs in the liver were detected, and the levels of tumor necrosis factor-α(TNF-α) and nitric oxide (NO) secreted by KCs were measured. Results The weight, liver index, the levels of ALT, AST, TG, TC, and the levels of TNF-α and NO secreted by KCs in model group were higher than that in the normal group ( P < 0. 05). Histopathological examination showed hepatocellular macrovesicular steatosis, lobular inflammatory cell infiltration and necrosis. Compared with normal group, the shape and function of KCs in the liver changed largely. Furthermore, these changes of KCs were in accordance with the degree of steatosis, inflammation and necrosis in the liver of the model group. Conclusions The shape and function of KCs changed significantly in NAFLD induced by high-fat diet, and KCs disorder might be involved in the pathogenesis of NAFLD.

Objective To investigate the clinical value of heart-type fatty acid-binding protein ( H-FABP) and N terminal probrain natriuretic peptide (NT-proBNP) in sepsis patients with myocardium injury. Methods 118 sepsis patients were included as survivor group (68 cases) and death group (50 cases) according to their prognosis outcome. 50 healthy people were selected as control group. Creatase, H-FABP, NT-proBNP, APACHEⅡscore and 28 day morbidity of control group and sepsis patients were assessed at 1 h, 6 h after admission by physical examination . Results At 1 h after admission , APACHEⅡscore , H-FABP and NT-proBNP level in sepsis patients were significantly higher than control group (P < 0.05); APACHEⅡscore, H-FABP, NT-proBNP and cTnI level at 6 h after admission were higher than that at 1 h (P < 0.05); APACHEⅡscore, H-FABP and NT-proBNP level in death group were higher than survivor group at 1, 6 h after admission (P < 0.05), cTnI level at 6 h after admission was higher in death group (P < 0.05). Futhermore, H-FABP, NT-proBNP and cTnI at 6 h after admission were positively correlated with each other (both P < 0.05). At 6 h after admission , H-FABP showed a better predictive value of 28-day mortality than NT-proBNP and APACHEⅡscore (P < 0.05). Conclusion H-FABP and NT-proBNP may suggest important significance in early diagnosis and prognosis prediction of sepsis patients with myocardium injury.

Objective To discuss the effects of Liuwei Dihuang Decoction on expressions of TGF-β1 and complement regulatory protein CR1 of the renal on IgA nephropathy rats.Methods Forty SD rats were randomized into normal group, model group, tripterygium glycosides group and Liuwei Dihuang Decoction group after adaptive feeding for one week. Complex method was used to establish IgA nephropathy model. All administration groups were given relevant medicine for gavage for 4 weeks;urine routine, the number of urine erythrocyte and 24 h urine protein were detected;creatinine, urea nitrogen, total serum protein and serum alburin were detected from blood;the renal pathological changes were observed under light microscope by HE and Masson staining;the expressions of TGF-β1 and CR1 were detected by immunohistochemistry.Results Compared with model group,Liuwei Dihuang Decoction could significantly decrease the proteinuria and hematuria levels and renal fibrosis changes of IgA nephropathy model rats, reduce the expression of TGF-β1, and raise the expression of CR1 (P<0.05).Conclusion Liuwei Dihuang Decoction can delay the renal fibrosis in IgA nephropathy rats through reducing the degree of TGF-β1 and promoting the expression of CR1.
