Objective: To examine the correlation between paliperidone plasma concentration and clinical efficacy in the patients with schizophrenia. Methods:Totally 50 schizophrenia patients were treated by paliperidone. The plasma concentration of paliperidone was monitored by RP-HPLC at the weekend of the 2 nd, 4 th and 6 th week, the clinical efficacy was evaluated using the positive and negative syndrome scale ( PANSS) , and the correlation between paliperidone plasma concentration and clinical efficacy was analyzed. Results:The mean plasma concentration of paliperidone was (31. 89 ± 17. 36) ng·ml-1 at the weekend of the 6th week, and no cor-relation was found between paliperidone plasma concentration and the clinical efficacy (r=0. 146,P=0. 074). Paliperidone plasma concentration in 12 patients with adverse drug reactions (ADR) was higher than that in the patients without ADR [(45. 87 ± 19. 21)ng ·ml-1 vs (27. 06 ± 11. 13) ng·ml-1, P <0. 01]. Conclusion: Paliperidone plasma concentration shows significant individual differences. With the increase of paliperidone plasma concentration, clinical efficacy isn't necessarily improved, while the incidence of ADR may be increased. Therefore, the monitoring of paliperidone plasma concentration is recommended to optimize the therapeutic reg-imen.

PURPOSE: This study aimed to identify the differences in functional fitness between older adults who were at risk of falling and those who were not. METHODS: A total of 104 older adults aged 65-74 years were recruited from a local community senior center. They were independent older adults without a history of falls in the preceding 12 months. Falling risk status was assessed using the Fall Risk Test. Five dimensions of functional fitness with seven testing parameters (i.e., 30-second chair stand test, 30-second arm curl test, 2-minute step test, chair sit and reach test, back scratch test, 8-foot up and go test, and body mass index) were evaluated by the Senior Fitness Test. RESULTS: Only 78 participants completed all the tests, of which 48 participants were identified with risk of falling, and 30 participants were free from risk of falling. Results from multivariate analysis of variance found significant differences on the combined outcome variables, especially in the 8-foot up and go test, 2-minute step test, and 30-second arm curl test. Results from discriminant analysis found a significant discriminant function among all the seven testing parameters, where the 8-foot up and go test, and the 2-minute step test contributed most. CONCLUSIONS: Older adults who are at the early stage of risk of falling tend to have lower functional fitness capacities, especially in agility and dynamic balance, aerobic endurance as well as in a combined relationship among all the testing parameters.

Aim To investigate the effects of osthole ( Ost) on the ability of proliferation and differentiation in APP transduced neural stem cells( NSCs) , and neu-ronal apoptosis, in order to find related mechanism. Methods A model of Alzheimer′s disease( AD) cells was successfully established by transducing APP gene into NSCs in vitro. The ability of proliferation and dif-ferentiation was tested by staining. The viability of NSCs was determined by using CCK-8 assay. The cell apoptosis was tested by Hoechst 33258 staining. The expression of GSK-3β and β-catenin mRNA was deter-mined by RT-PCR. The expression of GSK-3β and β-catenin protein was determined by Western blot. Re-sults The ability of proliferation had increased by 10 . 24% with Ost treatment, compared with APP group. The ability of differentiation had increased by 6 . 74%with Ost treatment, compared with APP group. The vi-ability of NSCs had increased and cell apoptotic rate had decreased significantly. From the results of RT-PCR and Western blot, we could find the expression of GSK-3βmRNA and protein had decreased, and the ex-pression of β-catenin mRNA and protein had increased significantly, compared with APP group. Conclusion Ost could enhance the ability of proliferation and dif-ferentiation into more neurons of NSCs transducing APP gene, and reduce neuronal apoptosis. It might be relat-ed with activiting Wnt/β-catenin signaling pathway.

Objective To explore clinical application value of Traditional Chinese Medicine nursing technology to decrease postoperative complication after breast cancer surgery.Methods Randomized controlled trial,large sample size,multicenter study design were adopted,and 200 patients who met inclusion criteria were randomly divided into the control group and the treatment group (100 cases in each group).The control group received routine nursing methods after breast cancer surgery.The treatment group received routine nursing methods as well as Traditional Chinese Medicine nursing intervention,such as auricular application pressure,acupoint sticking,meridian moxibustion.Data of arm circumference,Athens insomnia scale(AIS),symptom in affected arm were collected a week before and after surgery,and range of motion of shoulder joint was evaluated 3 months after surgery to compare postoperative subcutaneous effusion,skin flap necrosis,limb edema,sleep disorder and occurrence of shoulder joint dysfunction in two groups.Results The cases developed postoperative subcutaneous effusion,skin flap necrosis,limb edema were different in two groups,but the differences were not statistically significant(P＞0.05).There were significant differences between two groups in affected arm pain,swelling,skin tension,sleep,and shoulder joint dysfunction after 3 months(P＜0.05).Conclusion Traditional Chinese Medicine nursing technology can effectively decrease postoperative complication after breast cancer surgery.

Objective To observe the efficacy of Picture Exchange Communication System (PECS) on children with autism applied in rehabilitation nursing care. Methods 40 children with autism were divided randomly into two groups. The control group (n=20) received routine nursing care, and the observation group (n=20) received rehabilitation nursing care based on PECS for 6 months. They were assessed with Psycho-Education Profile (PEP-3) before and after training. Results The scores of PEP-3 improved obviously in all the children (P<0.05) after training, and the score of communication and behaviour improved more in the observation group than in the control group (P<0.05). Conclusion PECS applied in rehabilitation nursing care can improve the sociality and speech for children with autism.

Aim To investigate the effects of neurotro-phin-3 ( NT-3 ) gene overexpression on the differentia-tion into cholinergic neuron of neural stem cells ( NSCs) in vitro and its underlying mechanism. Meth-ods Brain-derived NSCs from newborn mice were iso-lated and cultured in vitro and determined by immuno-fluorescence. The NSCs were divided into three groups: NSCs, GFP-NSCs and NT-3-NSCs groups. The expression of NT-3 was detected by immunofluo-rescence and ELISA. Then, the ability of NSCs on dif-ferentiation into cholinergic neuron was detected by im-munofluorescence and RT-PCR, and the Acetylcholine Assay Kit was used for acetylcholine ( ACh) , and the expression of Hes1 , Mash1 and Ngn1 mRNA was de-termined by RT-PCR. Results The neurosphere dis-played Nestin and Sox 2-postive by immunofluores-cence, suggesting that the cultured cells were NSCs. The proportion of ChAT immunopositive cells was sig-nificantly higher in the NT-3-NSCs group than that in the other two groups ( P <0. 01 ) . Ach secretion in NT-3-NSCs was significantly elevated compared with the other two groups ( P <0. 01 ) . NSCs transfected with NT-3 increased the levels of Mash1 and Ngn1 mR-NA, and decreased the level of Hes1 mRNA ( P <0. 05 ) . Conclusion NT-3 can significantly promote the in vitro differentiation of NSCs into cholinergic neu-rons via probablly inhibiting Notch signaling pathway.
