Each second -order factor was composed of two first -order factors: instrumental enrichment and psychological enrichment. ②The structure validity and criteria-related validity of this work- family enrichment questionnaire were good. ③ The Cronbach ? of work to family enrichment and family to work enrichment were 0.86、0.84. The Cronbach ? of the whole questionnaire was 0.89. Conclusion: Work-family enrichment questionnaire has good construct validity、criteria-related validity and internal consistency reliability.

Objective: To examine the correlation of symptomatic feature and exploratory eye movements in schizophrenia. Methods: The eye movements of 60 patients with schizophrenia and 30 healthy control subjects were measured by the eye-mark recorder (model IV, Japan) and symptom profiles of patients were assessed using the Positive and Negative Syndrome Scale (PANSS) . Pearson correlation analysis was performed to examine the relationship between five-factor scores of PANSS, positive symptoms, negative symptoms and exploratory eye movements respectively. Results: The differences of all indices of eye movements between schizophrenic groups and normal control group had statistical significance ( P

Cerebral ischemia tolerance was induced by exercise preconditioning, which protected the brain from injury. The detailed mechanism of exercise preconditioning protecting cerebral ischemia injury was complicated, which involving the regulation of multiple tar-get point and multi-path, such as inhibiting cell apoptosis, promoting angiogenesis in the brain, inhibiting the excessive activation of glutam-ic acid as well as the regulation of inflammation. More mechanisms were still unknown.

Objective To investigate the changes of expression of apoptosis-related proteins Bcl-2,Bax and Fas of the transplantated hepatocytes after intraperitoneal transplantation in rats using porcine hepatocytes cultured with polylactic acid-O-carboxymethylated chitosan nanoparticles.Methods Recirculating collagenase perfusion method was used to isolate porcine hepatocytes.At 48h after D-galactosamine intraperitoneal injection,5 mL polylactic acid-O-carboxymethylated chitosan nanoparticles-cultured porcine hepatocytes embedded in collagen gel(group A) and 5 mL porcine hepatocytes embedded in collagen gel(group B) were transplanted into peritoneal cavity of SD rats,respectively.The amount of transplanted porcine hepatocytes was 5.0?107 hepatocytes in two groups.The expression of Bcl-2,Bax and Fas in transplanted hepatocytes three days after transplantation was detected with immunohistochemistry.Results At 1,2 and 3d after transplantation,the rates of Bcl-2 positive cells in group A was significant higher than those in group B,whereas the rates of Bax and Fas positive cells in group A were significant lower than those in group B(P

BACKGROUND: The change of the axial angle of the lower limb is related to the occurrence and development of osteoarthritis.OBJECTIVE: To analyze the correlation between the change of lower limb power line and pain area in the knee osteoarthritis patients.METHODS: Totally 65 knee osteoarthritis patients were selected as pain group and 30 healthy people were selected as control group. All the participants took anteroposterior and lateral knee radiographs through PACS imaging systems to collect six imaging indexes, including install index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio, femoral angle, tibial angle and tibiofemoral angle. Knee osteoarthritis patients in pain group were divided into two common clinical pain areas which were proparea and medial area.RESULTS AND CONCLUSION: (1) The insall index, the degree of tibiofemoral joint subluxation, tibiofemoral inside andoutside joint clearance ratio between knee osteoarthritis patients in pain group and people in healthy control group hadsignificant differences. There was no statistical significance in the femoral angle, tibial angle and tibiofemoral angle. (2) In terms of the comparison between proparea and medial area in knee osteoarthritis patients in pain group, tibiofemoral joint subluxation degree was statistically different. (3) These findings suggest that there was a higher patella in knee osteoarthritis patients who were in pain, more severe in the degree of tibiofemoral joint subluxation, and more limited in tibiofemoral inside and outside joint clearance ratio. The degree of tibiofemoral joint subluxation of proparea was more severe than medial area in pain group.

Objective:To establish an HPLC method for the determination of genistein in genistein-loaded Eudragit nanoparticles. Methods:The HPLC analysis was carried out on a DiamonsilTM C18(250 mm ×4.6 mm,5μm)column with the mobile phase of meth-anol-water (85∶15) at the flow rate of 1. 0 ml·min-1 . The detection wavelength was set at 261nm and the column temperature was 25℃. Results: A good separation was displayed between the drug peak and the excipient peaks. An excellent linearity range for genistein was obtained from 1.0 μg·ml-1 to 100.0 μg·ml-1(r =0.999 8). The recovery of genistein was 99.85%(RSD =0. 65%,n=9). Conclusion:The method is simple, rapid, accurate and specific, which is suitable for the determination of content and encapsulation efficiency of genistein-loaded nanoparticles.

BACKGROUND:Fracture healing is the coupling interaction of osteoblasts and osteoclasts that promotes bone growth, in which osteoblast-mediated bone resorption and osteoclasts-mediated bone reconstruction make the bone reconstruction in a dynamic equilibrium to promote bone growth. However, the majorities of the current studies focus on osteogenic or osteoclastic mechanism alone, and ignore the interaction mechanism between these two cels under co-existing conditions.
OBJECTIVE:To investigate the effects of Kidney Chinese Herbs on osteoblasts and osteoclasts coupling of osteoprotegerin-receptor activator of nuclear factor kappaB ligand-receptor activator of nuclear factor kappaB and its mechanism of action in fracture treatment.
METHODS: Mouse osteoblasts and osteoclasts were isolated and cultured in vitro to establish the mouse “osteoblast-osteoclast co-culture system” as a research platform. Then, Kidney Chinese Herbs at doses of 1.25, 2.5, 6.25 g/(kg?d) were given intragastricaly for 7 consecutive days. Mice in the blank control group were fed with the same volume of normal saline.
RESULTS AND CONCLUSION:The alkaline phosphatase activity in osteoblasts co-cultured with osteoclasts was significantly higher than that in osteoblasts cultured alone at 24 hours of culture (P < 0.05). Real-time PCR showed that in the co-culture system, the expression of alkaline phosphatase, Runt related transcription factor 2 and osteoprotegerin were increased in a dose-dependent manner (P < 0.05). Western blot assay showed 6.25 g/(kg?d) Kidney Chinese Herbs could dramaticaly promote the expression of osteoprotegerin and receptor activator of nuclear factor kappaB ligand, but restrained the expression of receptor activator of nuclear factor kappaB (P < 0.05). These findings indicate that Kidney Chinese Herbs can dynamicaly regulate the osteoprotegerin-receptor activator of nuclear factor kappaB ligand-receptor activator signaling pathway, and has a positive effect to promote bone reconstruction and rehabilitation.

Objective:To investigate the competency of informed consent in new admitted schizophrenia pa-tients.Methods:Fifty-three patients who were consecutively admitted to the hospital and diagnosed as schizophrenia according to the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision (ICD-10)were recruited and assessed in seventy-two hours.The competence of informed consent was assessed by the MacArthur Competence Assessment Tool-Treatment (MacCAT-T).The insight was assessed by the Insight and Treatment Attitude Questionnaire.The severity of illness was assessed by the Brief Psychiatric Rating Scale (BPRS).Correlations between the competence of informed consent and the factors mentioned above were discussed.Results:Forty-five (84.9%)patients had lower MacCAT-T scores,especially the scores of understand-ing dimension (1.58 ±1.85)and appreciation dimension (2.40 ±1.47).The competence of informed consent was significantly correlated with insight (r =0.73,P <0.01)but not correlated with age,education,duration of illness and BPRS scores.Logistic regression demonstrated that insight (OR =0.69)was a protective factor of competence of informed consent while thought disturbance (OR =1.39)was a risk factor.As to the involuntary admitted pa-tients,34.1% of them had competence of informed consent.Conclusion:The competence of informed consent in new admitted schizophrenia patients is widely impaired especially in understanding and appreciation dimension.The competence of informed consent is correlated with insight and thought disturbance.Voluntary or involuntary hospi-talization does not reflect the level of competence of informed consent.
