Objective To investigate the effect of protection motivation intervention on patients with diabetic cataract after implantable collamer lens implantation. Methods A total of 118 diabetic cataract patients were divided into 2 groups (59 cases each) by random digits table method. The control group received routine ophthalmic nursing and the observation group was given protection motivation intervention based on the routine nursing. The change of the plasma glucose, postoperative visual acuity and the quality of life were evaluated. Results The blood glucose on the morning of the operation day and one day after operation in the observation group was (8.27±1.25) mmol/L, (9.52±2.44) mmol/L, which was significantly lower than that of the control group, (10.49 ± 1.48) mmol/L, (12.77 ± 3.36) mmol/L, the difference between the groups was statistically significant (t=-5.392,-6.755, P<0.01). After 1 month and 3 months, the vision of the observation group was 0.64±0.22, 0.67±0.30, which was higher than that of the control group 0.56± 0.18, 0.58 ± 0.20, in which the postoperative blindness or low vision rate was 3.95%(3 eyes) in the observation group, and 13.51%(10 eyes) in the control group(t/χ2=2.492, 2.209, 4.013,P<0.05). The quality of life in the observation group was 7.70±1.13 and 5.22±1.48 in the control group, there was statistical significance between the two groups(t=3.660, P < 0.05). Conclusions Application of protection motivation intervention on diabetic cataract patients can improve their postoperative vision and quality of life.

Objective To observe the effects ofLinggan Wuwei Jiangxin Decoction on contents of cAMP, cAMP dependent PKA and AQP5 of model rats with clod phlegm-fluid lying latent in the lung asthma;To discuss its mechanism.Methods Ovalbumin intraperitoneal injection and atomization motivation + cold stimulation were used to establish models. Ninety rats were randomly divided into blank control group, model group, hexadecadrol group, andLinggan Wuwei Jiangxin Decoction low-, medium-, high-dose groups. All administration groups were treated with relevant medicine. The levels of cAMP, PKA, and AQP5 were detected by ELISA.Results Compared with the blank control group, the levels of cAMP, PKA, and AQP5 of rats in model group decreased obviously (P<0.05). Compared with the model group, the levels of cAMP, PKA, and AQP5 of rats in all administration groups increased (P<0.05), which increased dramatically inLinggan Wuwei Jiangxin Decoction high-dose group.ConclusionLinggan Wuwei Jiangxin Decoction can regulate the normal secretion of cAMP, PKA, and AQP5 in serum of rats with clod phlegm-fluid lying latent in the lung asthma, increase secretion of air passage liquid and decrease mucoprotein concentration, through which plays the role of treating asthma.

Objective Effect of psychological intervention on functional rehabilitation of femoral supracondylar fractures.Methods 84 type C fracture patients according to AO criteria for the diagnosis were collected,and randomly divided into intervention group(n=42)and control group(n=42)according to patient sex,age,fracture condition,cultural degree balanced matching principle.The control group was given conventional treatment and fracture features of health guidance,the intervention group in addition to conventional treatment and rehabilitation guidance.Comprehensive mental intervention applied 4 times on postoperative 3 days,the 2nd,3rd,4th week.Self-anxiety scale and self-depression scale were used before operation and 6th month after operation.Results The anxiety and depression scores in two groups before intervention showed no significant difference P>0.05).6 months after the operation,the anxiety score(41.6±9.4 vs 48.7±8.5)and depression score(40.6±7.6 vs 47.4±9.2)in intervention group apparently decreased than that in control group(P<0.01).Function restoration of knee joint in different effect showed better than control group(u=-2.0591,P<0.05).Conclusion Psychological intervention can effectively promote the functional recovery of patients with femoral supracondylar fractures and promote anxiety and depression mood.

Objective To investigate the current status of health education among nursing undergraduates,to analyze the existing problems and to bring up corresponding strategies for improving the health education ability for nursing undergraduates.Methods Totally 381 nursing undergraduates were recruited and investigated with a self-designed questionnaire.Aspects of students' cognition of health education,influencing factors of health education and the implementation of health education in clinic were investigated.Data were processed using SPSS 12.0 and percentages were calculated.Resuits 98.75％ students understood the importance of heath education in nursing work.However,systemic training courses of health education for nursing undergraduates were insufficient in both colleges and hospitals.Meanwhile,clinical teachers' ability of health education was limited.Only 15.59％students provided health education for patients independently.Conclusions Nursing colleges and practicing hospitals should strengthen health education consciousness of nursing undergraduates,enhance faculty construction and should set up related courses to train the health education skills.

Objective To prepare monoclonal antibody against Prostate Stem Cell Antigen(PSCA) and explore the inhibitory effects of Anti-PSCA mAb in treatments of human prostate cancer xenografts in mice. Methods Balb/c mice were immunized by PC-3 cell line. After fusing and screening, the anti-PSCA McAb’s characterizations were determined. Solid tumors in mice were produced by subcutaneous injection with PC-3 cells in the flanks of the mice.We picked out 10 mice bearing human prostate cancer xenografts.They were divided into a treatment group (n_1=5) and a control group (n_2=5).200 ?g Anti-PSCA mAb was injected into abdominal cavity of each mouse of the treatment group and PBS for them of the control group.Anti-PSCA mAb and PBS were administered once every three days for consecutive three times.The mice survival conditions of two groups were recorded during 5 weeks.The serum PSA, the tumor weights and dimensions of survived mice were measured.The tumor volume inhibition rate was calculated. T-test was performed to compare differences of PSA in serum,tumor weights and volumes between the treatment and control groups.Routine pathological slides of tumor tissue were observed under light microscope to evaluate the range of tumor tissues damaged by Anti-PSCA mAb. Ultrastructure was observed with transmission electron microscope. Results A marine McAb was produced, which raised against PSCA,belonged to IgG1 subclass. The average PSA serum level of the two groups were(3.28?0.55)ng/ml and(7.26?0.43)ng/ml.The weights of tumors of the two groups were(0.95?0.17)g and(3.08?0.18)g.The volumes of them were(164.59?14.08)mm3 and(548.49?19.79)mm3.There are remarkable differences between the treatment group and the control group(P
