Objective To evaluate the effects of occupational therapy and Taoist cognitive psychotherapy on emotional disorder of stroke patients.Methods A total of 136 hemiplegic patients with emotional disorder were randomly divided into a general treatment group,a cognitive psychotherapy group,an occupational therapy group and a combined therapy group(occupational therapy combined Taoist cognitive psychotherapy group).All patients were treated accordingly for 8 weeks and followed up for 6 months.All the patients were evaluated with Fugl-Meyer Assess- ment,COPM and SCL-90.Results It was found that the Fugl-Meyer Assessment and COPM scores were improved gradually in all groups.The combined therapy group scored higher than occupational therapy group(P

Objective To study the risk factors affecting neoplasm recurrence and survival of hepatocellular carcinoma(HCC)following liver transplantation(LT).Methods The clinicopatholo gic data,neoplasm recurrence and survival results of 118 patients with HCC receiving LT were retro- spectively analyzed and various clinicopathologic risk factors for neoplasm recurrence and survival were evaluated by univariate and multivariate analysis.Results The follow-up time ranged from 1 to 32 months.The recurrence rate was 37.3% and the mortality was 35.5%.The 12-,18-,24-month survival rate was 84.55%,70.30% and 62.24%,respectively.The 12-,18-,24-month neoplasm free survival rate was 69.05%,66.93% and 61.38%,respectively.In the univariate analysis,por- tal vein neoplasm thrombus(PVTT),Milan-criteria,neoplasm size,histological differentiation and pTNM stage were associated significantly with neoplasm recurrence,and PVTT,Milan-criteria,pre- operative alpha-fetoprotein(AFP),histological differentiation and pTNM stage were associated signif- icantly with survival rate;In the multivariate Logistic regression analysis,PVTT and histological dif- ferentiation were independent predictive factors of neoplasm recurrence,and multivariate Cox regres- sion analysis showed that PVTT and AFP independently associated with prognosis.Conclusions PVTT and histological differentiation are the most important predictive factors of neoplasm recur- rence,and PVTT and AFP independently predict the survival of patients undergoing LT.

Background Oxidative damage plays an important role in pathogenesis of age-related macular degeneration( AMD ),and its mechanism is the destroy of blood-retinal barrier.Müller cells is a primary component to stabilize the inner barrier of the blood-retina.Researches showed that epidermal growth factor(EGF) can promote the proliferation and migration of animal Müller cells,but less study was found in the effect of EGF on human Müller cells. Objective The present study was to investigate the effects of EGF on the proliferation and migration of human Müller cells and its molecular mechanism. Methods Human Müller cell line MIO-M1 cells were cultured and incubated,and cultured cells were identified using glial fibrillory acidic protein (GFAP),factor Ⅷ,α-smooth muscle actin( α-SMA ),keratin and S-100.Different concentrations of EGF( 0,1,10,30,100 mg/L)was added in freeserum DMEM,and the positive rate of the cells was calculated using 5-bromo-2-deoxyuridine(BrdU) method.The cells were divided into EGF group,H2 O2 group,EGF + H2 O2 group,glucose oxidase ( GO ) group,GO + EGF group,EGF + LY294002+H2O2 group according to the different intervention,and the effects of LY294002 on the proliferation of Müller cells (A590 )were detected by colorimetric assay for cellular growth and survival( MTT assay).The scratch test of Müller cells was used to assess the influence of EGF(0,1,10,30,100 mg/L)on H2 O2-induced damage of human Müller cell.Western blot was used to detect the cell proliferation under the protection of EGF on co-cultured cells using LY294002 and H2O2 and the activation of Akt signal pathways. Results The proliferative rates of the cells were 28.0％,32.9％,39.0％ in 10,30,100 mg/L EGF groups respectively and obviously higher than those in 0,1 mg/L EGF groups (24.5 ％,26.2 ％ ).Under the H2O2 culture,GO culture,respectively,the A570 value of the Müller cell in high concentrations of EGF groups was significantly increased in comparison with lower concentrations EGF groups with the statistical significance among the groups( F=23.582,P=0.000).Compared with EGF+H2O2 group,the A570value of the Müller cells was lowed in EGF+LY294002+H2O2 group.The maximum migration rate of Müller cells was found in 10 mg/L EGF group.Western blot revealed that the presence of H2O2 reinforced the expression of Akt in Müller cells,however,pretreatment with 100 mg/L EGF antagonized the harmful effect of H2O2 on Müller cells.Meanwhile,pretreatment with EGF and LY294002 reduced the expression of Akt in Müller cells. Conclusions EGF can induce the proliferation and migration of human Müller cells with the strongest effect in 10 mg/L.100 mg/L exogenous EGF has a stronger protection to the Müiller cells against H2O2-induced cell damage by activating the PI3KAkt cell survival pathway.

Objective To investigate the association of platelet activating factor acetylhydrolase(PAF-AH) activity in children with primary nephrotic syndrome(PNS).Methods The plasma PAF-AH activity was measured in 78 children with PNS who were divided into 3 groups:steroid-responsive nephritic,steroid-dependent nephritic,steroid-resistent nephritic,after they had been given steroid for 6 months.The plasma PAF-AH activity were also measured in 60 healthy children at the same age,with spectrophotometric assay,at the ame time,the blood cholesterol was measured.Results The blood cholesterol has positive correlation with the plasma PAF-AH activity,there was no significant difference of the blood cholesterol among 3 groups in nephrotic syndrome children,there was a significant difference in the plasma PAF-AH activity among 3 groups in PNS children,but there was no significant difference in the plasma PAF-AH activity between the groups of steroid-responsive nephritic and healthy children.Conclusion Plasma PAF-AH activity is related to the sensibility to steroid treatment in children′s PNS,and the plasma PAF-AH activity in steroid-resistent nephritic is higher than steroid-dependent nephritic.It is a question that if gene mutation is related with PAF-AH activity.

Objective To release the correlation of point mutation of platelet activating factor acetylhydrolase(PAF-AH)gene and primary nephritic syndrome (PNS).Method According to the effect of hormonal therapy,94 children with PNS were divided into three groups:steroid-sensitive nephritic syndrome(SSNS),steroid-resistent nephritic syndrome(SRNS),steroid-dependent nephritic syndrome(SDNS).The point mutation of PAF-AH gene (G994T) were identified by molecular biology technique in children with PNS and 239 healthy children were set as control group.Results No statistics differences were found relating to the genotype and allele frequencies between patients with PNS,SSNS,SRNS and normal controls.But it is confirmed that the genotype and allele frequencies among patients with nephritic type nephritic syndrome (NTNS)was higher than patients with simple type nephritic syndrome(STNS) and normal controls.SDNS was higher than both SSNS and normal controls.The number of relapses during the first year after onset was significantly higher in the patients who were heterozygous for the mutant allele (GT) or homozygotes (TT) than in those of the GG homozygotes.Conclusion Most PNS children with PAF-AH gene mutation occurred at position 994 were NTNS.The risk of relapse during the treatment period was higher in patients with PAF-AH gene mutation occurred at position 994.

Objectives To explore the effects of aging on midgastric transverse band(MTB)and gastric emptying.Methods In our prospective study,57 healthy volunteer were divided into young, middle and old-age groups.After taking test meal labeled by 99mTc-iethylenetriaminepentaacetic acid(99mTc-DTPA), the pictures were collected using double probe single photon emission computed tomography(SPECT).Stomach in each frame of the pictures was divided into proximal, midgastric transverse band(MTB)and distal parts.And half gastric emptying time,gastric remnant rate at 90 min, areas of different gastric parts were tested and calculated respectively.Results Half gastric emptying time of whole stomach was(43.24± 11.87)min,(42.07 ± + 9.31)min and(45.81 ± 10.73)min in young,middle and old-age groups, respectively, with P＞0.05.Among young, middle and oldage groups, half gastric emptying time was(38.09 ± 10.26)min,(37.33 ± 9.28)min and(26.74 ± 12.07)min in proximal stomach, and it was(38.35 ± 12.96)min,(37.73 ± 7.46)min and(46.41 ± 10.74)min in distal stomach,respectively.The half gastric emptying time was significantly reduced in proximal stomach and increased in distal stomach in old-age group(both P＜0.05).The gastric nuclide remnant rate at 90min in total stomach was(30.38 ± 19.32)％,(29.03 ± 10.36)％ and(31.92 ± 13.47)％ ,in young, middle and old-age groups, respectively, with P＞0.05.This rate in proximal stomach was(25.01 ± 12.35)％,(26.36± 15.29)％ and(19.54±8.47)％ among three group, respectively.The rate in proximal stomach was(42.25 ± 12.36)％,(41.56 ±± 9.33)％ and(56.05 ± 11.72)％ among three group,respectively.The gastric remnant rate at 90min was reduced in proximal stomach and was increased in distal stomach significantly in old-age group(both P＜0.05).Compared with young and middle-age group,the old-age group showed no difference in areas of total stomach in all the time, while the areas were reduced in proximal stomach and increased in distal stomach significantly from 30 min to 90 min(all P＜0.05).Total stomach versus proximal and distal stomach showed no difference in count/pixel ratio in all time,while a count/pixel ratio was reduced in proximal stomach and increased in distal stomach significantly from 30 min to 90 min(both P＜ 0.05).Both areas and count/pixel ratio of MTB at 60 min and 90 min were significantly increased in old-age group(both P＜0.05).Conclusions The total gastric emptying is not delayed along with aging, while the gastric emptying is increased in proximal stomach and reduced in distal stomach in the elderly.This abnormity of intragastric distribution of food might be related with larger area of midgastric transverse band.

AIM:To explore the application of 10g/L cyclopentolate chloride eye drops in children, and to compare the different effectiveness of cycloplegia between 10g/L cyclopentolate chloride and atropine in Chinese children.METHODS:A total of 236 eyes of 118 children aged 3~12 years old were enrolled in this study including 80 eyes of 40 children with myopia, 156 eyes of 78 children with hyperopia and 146 eyes of 73 children combined with astigmatism. 10g/L cyclopentolate chloride eye drops were used once per 5min for 3 times and refractive diopter was obtained 1h after the last drop of cyclopentolate. Three days after that, 10g/L atropine was then used 1 time per night for 1wk and optometry was performed again. The children were divided into 3 groups ( myopia, hyperopia and astigmatism group ) according to the refractive status, in which astigmatism was independent of the degree of separation of cylinder statistics. The results of retinoscope refraction were then compared between 10g/L cyclopentolate and 10g/L atropine.
RESULTS:The refractive diopter was -2. 25±1. 31D after 10g/L cyclopentolate eye drops and -2. 23±1. 32D after 10g/L atropine in myopic group. The refractive diopter was 1. 35±1. 19D and 1. 38±2. 00D in astigmastic group. No significant difference was found in myopic group and astigmastic group (P= 0. 109, P= 0. 374). While in the hyperopic group, the refractive diopter was 3. 76±2. 4D after 10g/L cyclopentolate eye drops, which was lower than that after 10g/L atropine 4. 39±2. 6D (P=0. 000).
CONCLUSION: The results of this study suggest that 10g/L cyclopentolate chloride eye drops can be used in myopia and astigmatism children, and 10g/L atropine should be used in hyperopia children.

OBJECTIVETo investigate the effects of different implant thread locations on stress distribution in implant and bone under concentrated load, and discuss the best design of location of implant thread.

METHODSThe stress in implant-bone interface of implants with different thread locations (model A, B, C, D), which were loaded in axial and oblique 450 to axle, were analyzed by Solidworks 2005 plus and Cosmos/works 7.0 software.

RESULTSThe stresses in cervical cortical bone of implant with model C were lower than others. But under oblique load, the stresses of implant and cancellous bone in model C were higher than model A. The stresses distribution of model B was obviously concentrated, and under axial load, all kinds of stresses in this model were higher than others. The stress distribution in model A and D were more even, the stress concentrated more on implant neck, upper part of cortical bone and the lowest thread on implant. The stresses in interface under oblique load were much higher than those under axial load.

CONCLUSIONThe location of thread has effect on stress distribution in implant-bone interface. More attention should be paid to it when we design implants, and we should try to avoid oblique load in implant prosthodontics.
