Objective To test the reliability of the Chinese version of tridimensional personality questionnaire(TPQ) and to explore three-dimentional personality characteristics of heroin dependence. Methods Personality characteristics of 358 heroin dependers,114 male smoker and 200 normal controls were investigated using the TPQ. 78 heroin depender were examined 10 days later to test the reliability of TPQ.Results (1) Retest reliabilities of the three higher-order dimensions of the novelty seeking(NS),reward dependence(RD) and harm avoidance(HA) were all good( r =0.87,P <0.01;r =0.84,P <0.01,r =0.64,P <0.01).The dimension's Alpha split of NS or HA were 0.72 and 0.71,respectively. While RD's Alpha split was just 0.29. (2) NS was higher but not significantly in the heroin-dependenc group than normal controls(P =0.09),but the former had significantly higher HA and lower RD [(15.25±5.95) vs (13.22±6.27),t =13.65,P <0.01;(17.08±3.28) vs(18.29±3.83),t =15.07,P <0.01]. (3)There were significantly sex differences in all the three higher-order dimensions of TPQ in the heroin-dependence group( P <0.01). Male heroin dependers had significantly higher NS ,higher HA and lower RD than male controls[(16.99±4.76) vs(15.29±4.60), P =0.002;(14.46±6.01) vs (12.31±6.00),P =0.002],and male heroin dependers had significantly higher NS,lower RD than male smokers( P <0.001).Compared with female controls,female heroin dependers only had significantly higher HA.Conclusion Reliability of the TPQ is good. Sex difference in personality characteristics of heroin depender exits. Male heroin depender have high NS,high HA,and low RD,which can provide scientific data for early intervention of heroin dependence.

Objective To study the intelligence and memory impairment of patients with craniocerebral injury during traffic accident and its correlated factors. Method Data of psychological tests, eletroencepa-lograph (EEG) and brain image information of 652 subjects with brain injury who survived from traffic accident in Chengdu from Jan. 1,1999 to Dec. 31,2001 were collected and analysed. Results The average intelligence quotient (IQ) of patients in patients group was 77.85?15.97. 27.9 % patients's IQ was lower than 70. 51.9% patients's memory quotient (MQ) was lower than 51. The intelligence impairment was correlated with education level, left temporal lobe injury, three or more lobes of the brain injuried and EEG abnormality. Memory impairment was correlated with education level, interval between injury and e-valuation, brain stem injury, left temporal lobe injury, and EEG abnormality. Conclusion Impairment of intelligence and memory in different degrees were observed in most patients with traumatic brain injury during traffic accident. Intelligence and memory impairment were correlated with left temporal lobe injury, EEG abnormality, brain stem injury and education level.

Objective: To investigate relationship between cognitive function and quality of life of elderly living in beadhouses Method: 251 persons aged 55 or above living in three beadhouse for at least 1 year were assessed with GQOLI-74 (generic quality of life inventory-74), SAS (self-rating anxiety scale), CESD (center for epidemiologic studies depression scale), MMSE (mini mental state examination) and ADL (activity of daily living) Result: The elderly with low MMSE scores had lower scores in GQOLI-74 than that normal in MMSE assessment The quality of life correlated with depression and cognitive function Those in marriage had better life quality than those widowed Conclusion: Cognitive function is an important factor on quality of life of elderly living in beadhouses

In order to evaluate the expression of HLA-DR antigen in glandular cells in eutopic and ectopic endometrium in patients with endometriosis, 19 infertile patients with endometriosis were analyzed immunohistochemically by labelled streptavidin biotin (LSAB) method. Nineteen infertile patients without endometriosis were studied as controls. The results showed that the expression of HLA-DR antigen in the glandular cells in both eutopic and ectopic endometrium was increased significantly as compared with that in the controls (P < 0.01). It is likely that aberrant expression of HLA-DR antigen in endometriotic tissue is involved in abnormal immunogenesis of endometriosis.

The operation methods, clinical classification, postoperative function exercise of gluteal muscles contracture were investigated. Clinically and retrospectively, treatment of 1280 patients with gluteal muscles contracture, being subjected to a "Z-shaped" release lengthening operation and efficiency exercise, was clearly standardized. All the cases were followed up from 3 months to 2 years with the effective rate being 100%, the cure rate being 98.5%, the recent complications being 5% , and the far complications being 0.2%. It was concluded that the clear diagnosis combined with standarized operation and efficiency functional exercise could greatly improve the therapeutic effects of gluteal muscles contracture.

In order to investigate the effect of a new institute-designed absorbable hydroxyapatite microparticles/poly-DL-lactide (HA/PDLLA) fracture fixation devices on experimental fracture healing, 25 rabbits with a transverse transcondylar osteotomy of the distal femur were fixed intramedullary by a HA/PDLLA rod (4.5 mm in diameter, 30-40 mm in length). The follow-up time lasted 1, 2, 4, 6 and 12 week(s). Roentgenographic, histological and ultrastructural analyses were conducted. The results showed that allosteotomies united within 6 weeks without delay.No accumulation of inflammatory cells was seen. Ultrastructural studies showed that polymorphonuclear neutrophils and macrophages were observed mainly at the 1st week, but only few were noted at the 2nd week. The inflammatory and debridement stages were not prolonged. Large amount of active fibroblasts and some chondroblasts were observed at the 2nd week, suggesting a fibrous callus stage. The main cellularity at 4th week was osteoblasts and osteocytes. Part of osteocytes had already entered the static stage at the 6th week. Our experiment showed that the HA/PDLLA had good biocompatibility, sufficient mechanical streugth and caused no delay to the fracture healing.

In order to evaluate the changes of lipid perioxides (LPO) and superoxide dismutase (SOD) levels in peritoneal fluid in patients with endometriosis, the levels of LPO and SOD in peritoneal fluids from infertile women with endometriosis and with normal pelvis were measured. The result showed that the levels of LPO but SOD was elevated significantly in peritoneal fluid from women with endometriosis than in women with normal pelvis (P<0.01). It is suggested that free oxygen radicals may be involved in the pathogenesis of endometriosis associated infertility.
