RESUMEN
Objective To prepare a sustained-release membrane with longer adhesion time and dissolution time, and compare it with the commercially available oral ulcer membrane. Method Adhesion strength, adhesion time, swelling coefficient, dissolution time, etc. were used as the inspection indicators, and a combination of single factor inspection and analytic hierarchy process were used to screen the membrane -forming materials. The dispersion method of clotrimazole, ornidazole and borneol were investigated to prevent the drug from seed out. The method of combining orthogonal experiment and analytic hierarchy process were used to optimize the dosage of CMC-Na, PVA-1788 and glycerin; and the commercial products were compared. Results Through single-factor investigation and orthogonal experiment, the optimal ratio of excipients was selected as CMC-Na∶PVA-1788∶glycerol (3∶1∶0.08). The water-insoluble component clotrimazole, ornidazole and borneol were treated by precipitation in liquid with good effect. The best method was used to prepare the membrane. The adhesion strength was 102 g. The adhesion time was 55 min. The swelling coefficient was 1 939.52. The average dissolution time was 110 min. The appearance was white and the surface was free of bubbles, soft and elastic. The membrane forming time at 60 ℃ was 300 min and the demolding effect was better which could be completely peeled off with moderate thickness. Conclusion The oral ulcer membrane developed in this method has good appearance, comfortable use, strong adhesion, long adhesion time and dissolution time, and could stay on the ulcer surface for a long time to form physical isolation, and slowly release the drug during the dissolution process, which could play the role of long-term pain relief, antibacterial, anti-inflammatory and promote healing effects on oral ulcers.

Objective To explore the effect of the model of comprehensive nursing interventions based on time nursing in improving therapeutic effects and prognosis of patients with schizophrenia. Methods A total of 84 cases of patients with schizophrenia were selected and were divide into two groupsby the random number table—an experimental group and a control group , both of which were 42 cases. The model of comprehensive nursing interventions based on time nursing was adopted in the experimental group and routine nursing was given to the control group until their discharge. Before and after the interventions, the Brief Psychiatric Rating Scale(BPRS) was used to evaluate the severity of the disease. The Activities of Daily Living(ADL) and the Social Disability Screening Schedule(SDSS) were used to evaluate the patients′ abilities of daily living and social skills. After the interventions, a satisfaction survey was conducted. Hospitalization time and disease recurrence of the two groups were observed. Results After the interventions,BPRS scales, ADL scales and SDSS scales were (31.50±4.23), (89.37 ± 8.16)、(6.65 ± 2.02) points in experimental group, and (45.43 ± 5.62), (81.03 ± 5.92), (8.96 ± 2.26) points in control group, the differences are statistically significant (t =2.361, 2.047, 2.206,P<0.05).The rates of satisfaction of the two groups was 95.24%(40/42) and 80.95%(34/42), and there was significant difference(χ2=6.892,P<0.05). Hospitalization time was respectively (42.86 ± 6.21)d and (67.49 ± 7.65)d in experimental group and control group, and and there was significant difference(t=2.253,P<0.05). Disease recurrence was respectively4.76%(2/42) and 23.81%(10/42),and there was significant difference(χ2=7.437, P=0.024). Conclusions The model of time nursing, with higher satisfaction level, shorter hospitalization time, and lower recurrence rate, can significantly improve the symptoms of patients with schizophrenia and enhance their self-care and social life abilities. It is worth popularizing in clinical nursing.

Objective To investigate efficacy and effect on liver function of the experimental therapy with balloon catheter to block the main artery temporarily and then pressurize chemoembolization to treat hypovascular liver cancer. Methods Eighty patients with hypovascular liver cancer requiring interventional therapy were randomly divided into two groups.The experimental group was treated with the new therapy and the control group was treated with traditional therapy. The lipiodol-filling status and maximum diameter of the tumor was analyzed for a midterm outcome,and the change of AFP and liver function were evaluated.Mann-Whitney test was used for data between two groups,Friedman test was used for data of each group,and Spearman nonparameter relevant analysis was used for efficacy indexes.Results ( 1 ) All Patients have confirmed diagnosis of hypocvascular liver cancer and got balanced baseline. ( 2 ) Lipiodol-filling status:the clinical efficacy and benefit rates of patients from experimental group were higher than that from control group and showed statistically significant difference in 1,3,12 months (Z =-2.135,- 2.939,- 2.686 ; P =0.034,0.004,0.007 ),but no statistically significant difference in 6 month ( Z =- 1.170,P =0.242 ).The status of lipiodol-filling of experimental group ( x2 =2.593,P =0.459 ) was more stable than control group ( x2 =10.886,P =0.012).(3) Maximum diameter of the tumor:the clinical efficacy and benefit rates of patients from experimental group were higher than that from control group and showed statistically significant difference in 3,12 months ( Z =- 2.734,- 2.733 ; P =0.006,0.006),but no statistically significant difference in 1,6 month ( Z =- 1.692,- 1.895 ;P =0.091,0.058). But neither of two groups showed statistically significant difference in change of maximum diameter of the tumor ( x2 =5.500,P =0.139 ; x2 =6.509,P =0.089 ).Relation between lipiodol-filling and maximum diameter showed positive correlation in 3 month ( r =0.257,P =0.035 ). (4) Stratified analysis was used for data of AFP according to AFP value before therapy,and two groups showed no statistically significant difference for patients belonging to 20-1000 μg/L by Pearson Chi-square test. (5)Two groups showed no statistically significant difference for data of liver function before therapy and in 1,3,6months ( Z =- 1.073,- 1.314,-0.518,-0.549;P=0.308,0.189,0.604,0.583).Conclusions According to the midterm result of this experiment,the experimental therapy increased lipiodol-filling and decreased maximum diameter of the tumor significantly in 3 and 12 months correspondingly,but no significant difference was observed in AFP and liver function between groups yet. So the long-term efficacy and its influence to lung metastasis and survival rate need further research.

Objective To investigate the distribution pattern of the ADAS-Cog scores among the elderly in Beijing and to evaluate the application of ADAS-Cog in distinguishing patients with mild Alzheimer's disease (AD) and healthy elderly. Methods In total, 1616 healthy elderly (NC), 125 elderly patients with non-AD disorders (ND), and 310 patients with probable AD including 201 patients with mild AD and 109 patients with moderate AD (by NINCDS-ADRDA criteria) were recruited in the study and their cognitive performance was measured by the ADAS-Cog.Results In NC group, those older than 80 years and those with less than 5 years schooling scored highest. There was statistically significant correlation between the total scores of the ADAS-Cog and age and duration of schooling in NC group (F=14.34, 113.27,both P<0.01). No correlation was suggested in the mild AD group. The total score of ADAS-Cog was significantly associated with duration of schooling in both moderate AD and ND groups (F=4.18, 8.72, both P<0.05). The total score of ADAS-Cog differentiated the patients with mild AD from NC healthy elderly with AUC ranging from 0.69 to 0.82 in each subgroup by age, and from 0.75 to 0.88 in subgroups by durations of schooling with the highest AUC of 0.88 in the subgroup having more than 15 years of schooling education. Conclusions The ADAS-Cog score in the healthy elderly is significantly associated with age and duration of schooling education. The ADAS-Cog can be applied in the cognitive assessment of Chinese AD patients. The total score of ADAS-Cog could efficiently differentiate patients with mild AD from healthy elderly, especially in subjects with higher education level.
