Toxicity of different processed was evaluated Polygoni Multiflori Radix by determining the hepatotoxic potency for selecting processing technology. Process Polygoni Multiflori Radix using high pressure steamed, Black Bean high pressure steamed, atmospheric steamed for different time. Using normal human hepatocytes (L02) as evaluation model, hepatotoxic potency as index to evaluate hepatotoxic potency of different processed Polygoni Multiflori Radix. Analysis chemical composition of some processed products by UPLC-MS. Hepatotoxic bioassay method cloud evaluate the toxicity of different Polygoni Multiflori Radix samples. Different processing methods can reduce the toxicity of Polygoni Multiflori Radix, high pressure steamed three hours attenuated was better. Different processing methods have different effects on chemical constituents of Polygoni Multiflori Radix. Comparing with crude sample, the contents of gallic acid, 2,3,5,4-tetrahydroxyl diphenylethylene-2-O-glucoside, emodin-8-O-beta glucoside and emodin were decreased in processed products with 3 kinds of different methods. The change trend of 2,3,5,4-tetrahydroxyl diphenylethylene-2-O-glucoside content was similar with hepatotoxic potency. Different processing methods can reduce the toxicity of Polygoni Multiflori Radix. Processing methods and time attenuated obvious impact on toxicity. Recommended further research on the attehuated standard control of Polygoni Multiflori Radix concocted.

Objective To evaluate the effect of self -efficacy training on hemiplegic patients after ischemic stroke. Methods Sixty cases were randomly divided into control group (n =30 )and self -efficacy training group (n =30).The self -efficacy group received rehabilitation training according to the self -efficacy theory (5 times /week, 40 min /per time,1 0 weeks of intervention).The movement and balance function were evaluated using Fugl -Meyer score (FMA)and the activities of daily living were evaluated by the task analysis scale and Barthel index.The self -efficacy level and quality of life were evaluated by the general self -efficacy scale (GSES)and medical outcomes study (SF -36).Results The scores of FMA,Barthel,SF -36 and GSES had no significant differences between the two groups before training (P >0.05 )and all indexes improved after training.Six scores of Barthel and all scores of FMA,SF -36 and GSES of self -efficacy group were significantly higher than those of control group after training (all P <0.05 ).Conclusion Self -efficacy application could improve the motor function on the rehabilitation of hemiplegic patients after ischemic stroke.

Objective To survey the stressors and pressure level of international tract nursing college students at campus to explore the methods for releasing stress, so as to promote their physical and mental health.Methods Stressors and pressure level on 714 international tract nursing students and 724 general nursing had lower learning efficiency, higher examination pressure and competition among students reached high pressure learning annoyance (P＜0.01), personal annoyance and total pressure (P＜0.05), but had lower negative life the first-year international tract nursing students were significantly higher than those of the second-year international tract nursing students (P＜0.01). Conclusions The results suggest that the stressors on international tract nursing students is mainly from learning annoyance, thus the methods to ease the pressure,such as psychological support, establishment of practical learning objectives, and their adjustment to the new environment for freshmen, are expected to be adopted.

Objective To evaluate the intervention effects of cognitive behavior therapy (CBT) on the patients with first episode schizophrenia. Methods A total of 80 patients with first episode schizophrenia were randomly divided into study group (n =40) and control group (n =40). The study group was treated by routine drugs and psychiatric nursing after two weeks combining with CBT while the control group was treated only by routine drugs and psychiatric nursing. Both groups were assessed with Positive and Negative Syndrome Scale (PANSS), Nurses Observation Scale for Inpatient Evaluation (NOSIE) , Scale of Social-skill for Psychiatric Inpatients (SSPI) , and Symptom Check List-90 (SCL-90) before and after CBT intervention. The scores of those scales were compared between two groups. Results There were significant differences after CBT intervention in all factors, total negative factors and total positive factors of NOSIE, total score of SSPI and PANSS (P<0.01) between two groups. Factors score of interpersonal sensitivity, depression, anxiety, panic, paranoid ideation, and psychosis of SCL-90 in the study group decreased significantly after intervention. Conclusions It is suggested that CBT can improve social function and quality of life and facilitate recovery of the first-episode schizophrenia patients.

Objective To study the pharmacokinetics of iloperidone in healthy volunteers.Methods The study was a random , open, double cycle and cross trial.Sixteen healthy volunteers were randomly divided into two groups (8 volunteers in each group ).A single dose of 1 and 3 mg iloperidone was administrated in each group , respectively.The con-centration of iloperidone in human plasma was determined by HPLC -MS/MS.The main pharmacokinetic parameters were calculated with WinNonlin 6.1.Results The main parameters of a single dose of 1 mg and 3 mg of iloperidone were as follows:t1/2were (54.06 ±49.61 ), and (34.92 ±28.42 ) h,ρmax were (0.72 ±0.33 ), and (7.26 ±4.47 ) ng· mL-1, tmax were (2.04 ±0.66 ), (1.43 ±0.33 ) h, and AUCinf were (14.30 ±7.81 ) and (71.90 ±36.48 ) ng· h· mL-1 , respective-ly.Conclusion The process of iloperidone in the dosage range of 1 to 3 mg fits the nolinear dynamic feature in Chinese healthy volunteers.

Background: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY= 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. Results: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27％ was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage Ⅰ, 39,302 CNY for stage Ⅱ, 40,353 CNY for stage Ⅲ, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02％ of the overall expenditure. Conclusions: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.
