Objective To survey prevalence of behavior problems in children of off-farm workers and effects of family factors on children' s behavior problems.Methods The study was done in the whole 7 schools for off-farm workers' children in Shanghai Baoshan district,including all 3 ～ 6 grades students of primary school and 1 ～3 grades students of junior high school.Totally 4350 students finished survey (95.4％).Achenbach' s child behavior checklist ( CBCL,parent' s version) and general family questionnaire were used.Results ( 1 ) Prevalence of behavior problems in children was 11.2％ ; 12.8％ 12 ～ 16 years children had behavior problems( 14.7％boys and 10.4％ girls) ; 11.4％ of one-child children had behavior problems compared with that of 11.2％ child with siblings children ( x2 =0.038,P ＞ 0.05 ).(2) Total score ( 20.64 ± 17.67 ) and factor scores of thought problems,depressed,hyperactivity,delinquent rule-breaking behavior were higher than those of Chinese norm (P ＜0.05 or P ＜ 0.01 ) among 6 ～ 11 years boy group.Total score ( 17.23 ± 14.73 ) and scores of thought problems,depressed,social problems,hyperactivity,delinquent rule-breaking behavior were higher than those of Chinese norm (P ＜ 0.01 ) among 6 ～ 11 years girl group.Among 12 ～ 16 years boy group,total score (20.44 ± 19.32) and all factor scores of CBCL were higher than those of Chinese norm(P＜0.01 ).Total score ( 17.02 ± 16.72) and scores of immature,delinquent rule-breaking behavior,brutality were higher than those of Chinese norm(P ＜ 0.05 or P ＜0.01 ) among 6 ～ 11 years girl group.(3)Multi-regression analysis showed that poor parent-child relationship was the most important predict factor for higher score of CBCL among all family risk factors (P ＜ 0.05 ).Conclusion Children of the off-farm workers and their families need special mental health care program.

Objective To investigate the secretory capacity and apoptosis of interleukin ( IL)-21 induced normal B cells by co-culture with serum from patients with systemic lupus erythematosus (SLE). Methods Serum from twenty new-onset SLE patients and 20 healthy donors were collected .CD1+9 B cells from the normal controls were co-cultured with serum from SLE patients in the presence or absence of IL-21-R-FC(4 μg/ml).Supernatant IgG and IgM concentration were measured by immunoturbidimetric assay on day 5.Supernatant anti-dsDNA level was determined by ELISA .The percentage of apoptotic cells was detected by flow cytometer.Results IgG,IgM and anti-dsDNA levels in normal B cells with SLE serum were significantly higher than those in the serum of SLE patients alone [ ( 5.84 ±1.79 ) g/L vs ( 4.25 ± 1.48)g/L,P=0.000;(0.46 ±0.21)g/L vs (0.43 ±0.21)g/L,P=0.003;(127.76 ±70.24)IU/ml vs (115.15 ±63.88) IU/ml,P=0.014 respectively].However, no significant differences were found in the group of normal B cells with non-homologous serum from normal controls (P>0.05).Supernatant IgG, IgM and anti-dsDNA levels in normal B cells with SLE serum significantly decreased while IL-21R-fusion protein was added [(5.26 ±1.62)g/L vs (5.84 ±1.79)g/L, P=0.006;(0.42 ±0.20)g/L vs (0.46 ±0.21)g/L, P=0.002;( 118.00 ±69.62 ) IU/ml vs ( 127.76 ±70.24 ) IU/ml, P =0.012 respectively ] .The apoptotic rate of B cells with SLE serum was significantly higher than that with normal serum [ ( 47.88 ± 12.65)%vs (38.86 ±10.32)%,P =0.004].But adding IL-21R-fusion conversed the apoptotic rates [(42.08 ±12.52)%vs (47.88 ±12.65)%,P=0.001].Conclusions SLE serum could induce normal B cells to form immunoglobulin secreting cells and producing autoantibodies , or apoptosis in pathological conditions.IL-21 might be considered as a potential therapeutic target of SLE .

Objective To evaluate the MRI findings and its diagnostic value in gluteal muscle contracture (GMC). Methods Eleven clinic or operation confirmed GMC patients were examined by plain X-ray and MRI. Conventional T 1WI and T 2WI MR imaging were performed and FFE-T 2WI (fast field echo-T 2WI) was also scanned. CT scan was conducted in 5 cases. Results 11 GMC patients were all diagnosed by MRI. Conventional T 1WI and T 2WI could only show the atrophy of gluteal muscles, while FFE-T 2WI could directly show the fibrous band of gluteal muscle and its fascia, and the fibrous band appeared as low signal intensity on FFE-T 2WI sequence. Conclusions MRI is the efficient modality in imaging the fibrous band for GMC patients, and FFE-T 2WI is the most valuable sequence. MRI is very helpful in the diagnosis and treatment of GMC.

Objective To evaluate the appearances of osteochondral fracture of the knee on X-ray and MR imaging. Methods Twelve patients with knee acute injury were examined with X-ray and MRI. The findings of MRI and X-ray were analyzed and reviewed, and the results of each patient were confirmed by arthroscopy and operation. Results Thirteen areas of osteochondral fracture including 9 loose bodies in 12 patients were diagnosed by MRI. Seven locations were found by MRI in the distal lateral femoral condyle, and 6 in patellar. MRI could clearly show the location, the size, and the depth of each osteochondral fracture, and MRI could also differentiate the articular cartilage and the subchondral of the loose body. T 2WI, STIR, and FFE-T 2WI were the best sequences to demonstrate the osteochondral fracture. X-ray showed 5 loose bodies in the knee joint, but could not detect where they came from. Conclusion MRI can accurately reveal and diagnose the osteochondral fracture of knee after trauma, which improves the diagnostic certainty and is very helpful for arthroscopy and operation. X-ray is still the initial modality in detecting the osteochondral fracture of knee and should be combined with MRI to confirm the diagnosis.

Objective:To elucidate the possible role of galanin in the development of experimental depression in rats. Methods:Openfield was performed to test the behavior of rats. The changes of the galanin level in different brain areas were determined by RIA. The effect of fluoxetine hydrochloride on galanin level were observed by intraperitoneal injection. Results:Compared to control group, the crossing times and rearing times decreased significantly in depressed rats, galanin level decreased remarkably in plasma, hypothalamus, hippocampus, forebrain, parietal lobe and temporal cortex of depressed rats. Intraperitoneal injection of fluoxetine hydrochloride obviously improved the depressed behavior in rats, increased the galanin level in the hippocampus and forebrain of depressed rats. Conclusion:Hippocampus and forebrain may be involved in the development of experimental depression and in the antidepressive effects of fluoxetine hydrochloride.

Objective To evaluate the value of MRI in diagnosing pigmented villonodular synovitis (PVNS). Methods MRI appearance of 23 pathologically proven cases of PVNS was analyzed. Results In 23 patients with PVNS, 9 cases occurred in knee joint, 9 cases in hip, 3 cases in ankle, 1 in elbow, and 1 in wrist. X ray of the 23 patients could only show the joint effusion, and bony erosion was found in 19 cases. CT scan showed joint effusion and bony erosion more clearly than X ray in 4 cases. The typical MRI appearance included intra articular joint effusion and extensive synovial proliferation which led to progressive destruction of cartilage and bone. The pigmented villonodules showed nodular low signal on both T 1WI and T 2WI, especially in FFE/T 2WI. Conclusion MRI is the most effective modality in the diagnosis of PVNS.

Ten dimeric phthalide racemates (1-10) were isolated from an aqueous extract of the Angelica sinensis root head (Guitou) by separation techniques of column chromatography over macroporous adsorbent resin, MCI resin, silica gel, and Sephadex LH-20, together with preparative thin-layer chromatography and reversed phase HPLC. The racemates were further separated into (+)-/(-)-1-(+)-/(-)-10 with chiral HPLC. Their structures including absolute configurations were elucidated by comprehensive analysis of spectroscopic data, combined with electronic circular dichroism (ECD) and NMR calculations as well as single crystal X-ray diffractions. Compounds (+)-/(-)-1-(+)-/(-)-10 are either new structure or new natural product, named (+)-/(-)-angelidipthalidic acids A-H [(+)-/(-)-1-(+)-/(-)-8] and (+)-/(-)-angelidipthalidols A and B [(+)-/(-)-9 and (+)-/(-)-10], respectively. Meanwhile, dimeric phthalide mono- and bis-lactone derivatives with 3.3′a,8.6′- and 3.6′,8.3′a-coupling patterns as well as determination of their relative configurations are discussed.
