Objective To investigate the reliability and validity of the Chinese version of the schizophrenia cognition rating scale ( SCoRS) . Methods 112 cases of schizophrenia or schizophreniform disorder inpatients were recruited and assessed using the SCoRS( Chinese version) ,the brief assessment of cognition in schizophrenia (BACS) and personal and social performance scale(PSP). The principle component analysis,reliability analysis and correlation analysis were used to analyze the data. Results Standardized Cronbach α = 0.964. All the 20 i-tems were significantly correlated. Except item 1 ,9,18,19 ( r=0. 830,0. 890,0. 871,0. 890) ,the interrater correlation coefficiency (ICC) of the rest of the items was over 0.9. The ICC of global rating scores between two raters was 0. 921. Factor analysis procedure identified three factors. Factor 1 reflected the neurocognitive state; factor 2 reflected the social cognitive state;and factor 3 mainly reflected the daily life function. The SCoRS rating scores were significantly correlated with the BACS and PSP scores. Conclusion The validity and reliability of SCoRS are acceptable. SCoRS is a useful tool for assessing the deficits of the cognitive function for Chinese schizophrenia patients.

Objective To study the changes of bone mineral density(BMD)and bone turnover in postmenopausal osteoporotic patients treated with salmon calcitonin nasal spray. Methods Sixty-seven postmenopausal osteoporotic patients were enrolled in our trial. All of them received calcium and vitamin D; 37patients were treated with salmon calcitonin nasal spray for 12 months and the other 30 patients received calcium and vitamin D only. Dual-energy X-ray absorptiometry(DEXA)and measurements of a series of bone turnover indices were performed before and after medication for 6 and 12 months. Results After treatment with salmon calcitonin nasal spray for6 months, BMD in lumbar spine 2-4 increased but no change occurred in femoral neck. However, after treatment for 12 months, BMD in both lumbar spine 2-4 and femoral neck increased. In the control group, BMD in lumbar spine 2-4 decreased after treatment for 6 and 12 months, but BMD in femoral neck decreased only after 12months. Comparing with the control group, after treatment with salmon calcitonin nasal spray, BMD in lumbar spine 2-4 and femoral neck were increased obviously. The level of TRACP-5b and NTX/Cr decreased after treatment with salmon calcitonin nasal spray for6 months and 12 months, while BALP increased only after treatment for 12 months. In the control group, BALP decreased after treatment for 12 months. The level of 25-(OH)vitamin D increased after treatment for 6 months and 12 months in both groups. Conclusions Long-term treatment with salmon calcitonin nasal spray prevents bone loss and may increase bone mass.

Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.

Objective To investigate the effects of 1,25-dihydroxyvitamin D3 [1,25 (OH)2D3] on PCNA expression and cell proliferation in human glomerular mesangial cells. Methods The cultured human mesangial cells, which was subcul?tured 3-8 generations, were randomly divided into four groups: normal control group (plus the DMEM medium containing 5%fetal bovine serum), proliferation in the control group (EGF group, plus 10μg/L of EGF), general intervention group [VD group, plus 10-8 mol/L of 1,25(OH)2D3], proliferation in the intervention group [EGF+VD group, plus 10μg/L EGF and 10-8 mol/L 1,25(OH)2D3] for treatment of 48 h. The cell cycle was detected by flow cytometry,and the expression of PCNA was detected by Western blot assay in four groups. Results (1) Compared with normal control group, G1 phase cells were signifi?cantly reduced, S, G2/M phase cells were increased and PI index was higher in EGF group. And G1 phase cells were signifi?cantly increased, S and G2/M phase cells were significantly decreased, and PI index was lower in VD group. Compared with the EGF group, G1 phase cells were significantly increased in VD group and EGF+VD group, and S, G2/M phase cells de?creased, PI index was lower. (2) Compared with normal control group, the expression of PCNA was higher in EGF group, and lower in VD group. Compared with EGF group, the expression of PCNA was lower in VD group and EGF+VD group. Conclu?sion 1,25 (OH) 2D3 inhibits the proliferation of human glomerular mesangial cells by arresting cell cycle and inhibiting the expression of PCNA protein.

Objective To investigate whether miR-122 is a target of oxymatrine against HBV. Methods HepG2.2.15 cells were incubated with culture medium containing different concentrations of oxymatrine. The cyto-toxicity of oxymatrine was determined by cck-8 assay. The surface antigen of HBV (HBsAg),antigenof HBV (HBeAg)and HBV DNA in supernatant and intracellular miR-122 were determined in HepG2.2.15 cells after incu-bation with culture medium containing oxymatrine for 72 h. Results The survival percentage of HepG2.2.15 cells under different concentrations of oxymatrine was higher than 95% when the concentration of oxymatrine was lower than 4 mg/mL. After treatment with oxymatrine for 72 h,the secretion of HBsAg and HBeAg,the level of HBV DNA in the supernatant were reduced. The intracellular miR-122 in oxymatrine experience group was 3.5 times higher than that in the negative control group. Conclusions Oxymatrine might be used to inhibit viral replication and antigen expression by enhancing the expression of miR-122 in HepG2.2.15 cells.

OBJECTIVE: To explore the mechanism of scalp acupuncture (SA) in treating cerebral ischemia. METHODS: Sixty SD rats with middle cerebral artery occlusion (MCAO) were randomized into untreated group and SA-treated group, with another group of 10 SD rats without artery occlusion as sham-operated control. Neurological severity score (NSS), hemetoxylin and eosin (HE) staining and enzyme-linked immunosorbent assay were applied to observing the changes of neurofunctional defect, inflammatory infiltration in cerebral tissue and content of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and IL-10 at 24, 48 and 72 h after ischemia-reperfusion. RESULTS: There existed significant difference in NSS between SA-treated group and untreated group (P<0.01), especially at 72 h after ischemia-reperfusion. The HE staining results of ischemic cerebral tissue showed an apparent reduction of inflamed lesions in SA-treated group as compared with the untreated group (P<0.01), especially at 72 h after ischemia-reperfusion. The content of TNF-alpha and IL-1beta at each phase point after ischemia-reperfusion in SA-treated was decreased as compared with that in the untreated group, and there were differences between SA-treated group and untreated group at 72 h after ischemia-reperfusion (P<0.01). An apparent increase was observed in IL-10 between SA-treated group and untreated group at each phase point after ischemia-reperfusion, and there were significant differences between SA-treated group and untreated group at 48 and 72 h after ischemia-reperfusion (P<0.05, P<0.01). CONCLUSION: Scalp acupuncture can improve neurofunctional rehabilitation, suppress leukocyte infiltration, decrease the content of TNF-alpha and IL-1beta within a certain range and enhance IL-10 expression so as to suppress cytokines-mediated inflammatory reaction and attenuate cerebral ischemia-reperfusion injury.

Objective: To explore the relationship between blood levels of cyclophilin A (CyPA) and chronic heart failure (CHF).
Methods: A total of 166 CHF patients were enrolled as CHF group, according to NYHA classiifcation, it was further divided into 4 sub-groups: Class I,n=37, Class II,n=39, Class III,n=46 and Class IV,n=44. In addition, there was a Normal control group,n=52. Blood levels of CyPA, B-type natriuretic peptide (BNP) and high sensitivity C-reactive protein (hs-CRP) were examined and compared among different groups.
Results: Compared with Normal control group, CHF group had elevated CyPA (5.11 ± 2.43) ng/ml vs (2.28 ± 0.61) ng/ml, BNP (385.65 ± 184.06) pg/ml vs (90.37 ± 18.44) pg/ml and hs-CRP (11.74 ± 5.44) mg/L vs (5.99 ± 1.14) mg/L, all P<0.05. As increased severity of NYHA classiifcation, blood levels of CyPA, BNP and hs-CRP between 2 subgroups had the increasing trend accordingly, allP<0.05; while there was an exception: blood levels of CyPA and hs-CRP were similar between Class I subgroup and Normal control group, allP>0.05. Pearson correlation analysis indicated that blood levels of CyPA were positively related to BNP and hs-CRP in CHF patients (r=0.838,P<0.01 and r=0.755,P<0.01).
Conclusion: Blood levels of CyPA were elevated in CHF patients and it’s obviously related to NYHA classiifcation, which might have certain effects on CHF diagnosis and evaluation.

A method was proposed for the separation and determination of paraffin waxes in food by HPLC-evaporative light scattering detection (ELSD). A normal-phase column was used to separate nonparaffinic and paraffinic materials without resolving the latter into individual components. The t-test method was adopted for the evaluation of mean difference between response factors of n-alkanes in paraffin waxes on ELSD detector. No mean difference was obtained between response factors, which can be used for quantitative determination of paraffin waxes in food. The determination results obtained by HPLC-ELSD were compared with those by GC-MS. The linear range for the determination of paraffin waxes was in the range from 10 to 500 mg/L with a correlation coefficient of 0.9988, and the limit of detection was 1.0 mg/L. With the spiking level of 10, 50 and 100 mg/kg, the recovery ranged from 84.6% to 105.4% and the relative standard deviation ranging from 5.4% to 7.2%. The proposed method is simple, fast and sensitive.

Objective To explore the underlying mechanisms of scalp electroacupuncture (SEA) in treating cerebral ischemia. Methods A total of 70 healthy male Sprague-Dawley rats were randomized into a sham operated group, a model group and a scalp electroacupuncture (SEA) group. Cerebral ischemia was induced in rats by middle cerebral artery occlusion (MCAO). Rats in SEA group were treated with scalp electroacupuncture immediately after the establishment of the cerebral ischemia model by inserting the needles along anterior oblique line of vertex-temporal and posterior oblique line of vertex-temporal, connecting to the Han's Electro-Acupuncture Apparatus. The rats in sham operated group underwent the same operation as that in SEA group but without occlusion. Neurological severity score (NSS) was obtained to evaluate the neurofunctional defect, hemetoxylin and eosin (HE) staining was used to observe the inflammatory infiltration in cerebral tissue, and enzyme-linked immunosorbent assay(ELISA) to measure the contents of IL-1 beta and IL-10 at various time points. Results SEA group demonstrated significant decline in NSS at 72 h after the operation when compared with that of model group (P < 0. 01 ). An apparent attenuation in in-flammatory infiltration was seen in SEA group comparing with that of model group, especially at 48 h and 72 h after operation (P <0.01 ). Apparent decrease in IL-lbeta in SEA group was observed when comparing with the model group at 72 h (P <0.01 ). Statistically significant increase in IL-10 content was seen in SEA group at 48 h and 72 h after operation comparing with that of model group. Conclusions Scalp electroacupuncture might exert brain pro-tection by suppressing leukocytes infiltration via up-regulation of IL-10 and down-regulation of IL-1 beta expression.
