Objective The aim of this study is to provide guidance on rehabilitation nursing via observing the effect of comprehensive relaxation training on perioperative psychological stress in patients with coronary intervention treatment. Methods In this study, eighty patients ready to receive coronary intervention were randomly divided into the experimental group and the control group (40 patients in each). The control group were treated with routine percutaneous coronary intervention care, and the experimental group received both comprehensive relaxation training and routine care. The anxiety state and subjective feelings on comprehensive relaxation training in both groups were dynamically investigated via State-Trait Anxiety Inventory questionnaire and subjective feeling questionnaire from pre-operation to 7 days after operation. Results Anxiety levels between two groups showed the similar trend, and there was statistically significance between two groupsin the state anxiety level. The subjective feeling in the experimental group improved. Conclusions The psychological stress in patients receiving coronary intervention surgery maintains at high level form pre-operation to 24h post operation, and comprehensive relaxation training can significantly reduce the level of state anxiety. These patients consider that this simple training shows obvious relaxing effect.

Objective:To explore the effect of case teaching in clinical nursing teaching and medical ethics ed-ucation in the department of cardiology. Methods: A sample of 75 nurse interns came to practice in November 2014 to April 2015 were allocated to the control group, while 96 nurse interns came in July 2015 to December 2015 were allocated to the experimental group. The interns in control group were taught according to the traditional teach-ing method, and the case teaching method was used in the experimental group. The scores of critical thinking abili-ty and the times of praise were compared between the two groups. Results:Both critical thinking ability and praise of the interns in the experimental group were better than those in the control group ( P<0 . 01 ) . Conclusion:In-troducing the case teaching method to clinical nursing teaching and moral education can improve nurse interns′clin-ical critical thinking ability and stimulate the enthusiasm for learning.

AIM: To study the inhibitory effects of nm23-H1 gene on proliferation and invasion of human lung adenocarcinoma A549 cell line. METHODS: Recombinant eukaryotic expression vector pcDNA3.1-nm23-H1 containing full length of human nm23-H1 cDNA was constructed and transfected into a human lung adenocarcinoma A549 cell line by lipofectamine. Cell strain that expressed nm23-H1 stably was screened out by G418 and named pcDNA-nm23-A549. Expression of nm23-H1 was identified by RT-PCR and immunohistochemistry. Growth curves were drawn to detect the inhibitory effects on cell proliferation. Cell cycle of pcDNA-nm23-A549 was examined by flow cytometry. Atomic force microscopy was used to observe the filopodia on the surface of the cells. RESULTS: Introduction of nm23-H1 obviously inhibited the proliferation of A549. Expression of nm23-H1 did not induce apotosis in A549 cells but increased the percentage of phase G_1 cells and decreased phase S cells. Meanwhile, phase G_1 to phase S transition was restrained. Filopodia in the cell surface was much fewer and its structure changed in cells transformed. CONCLUSION: nm23-H1 is capable of inhibiting A549 proliferation and decreasing its metastatic ability, probably by interfering with cell cycle and cell surface structure.

OBJECTVE:To investigate the clinical effect and safety of pregabalin combined with gabapentin in the treatment of central pain after cerebral infarction.METHODS:One hundred and fifty patients with central pain after cerebral infarction in our hospital from Jan.2010 to Dec.2015 in our department were randomly divided into group A,B,C,with 50 cases in each group.Group A was given Pregabalin capsule 75 mg,bid combined with Gabapentin capsule 0.1 g,tid;group B was given Pregabalin capsule 75 mg,bid;group C was given Gabapentin capsule 0.1 g,tid;3 groups were treated for 4 weeks.VAS score,NRS score,PSQI and SF-36 score were observed among 3 groups before and after treatment to evaluate clinical efficacies of 3 groups;the occurrence of ADR were recorded in 3 groups.RESULTS:The clinical total response rate of group A,B,C were separately 94.00％,74.00％,70.00％.The clinical total response rate of group A was significantly better than that of group B and C,with statistical significance (P＜0.05).After treatment,VAS score of group A,B,C were separately(3.87 ± 0.74),(5.10 ± 1.26),(5.03 ± 1.23);NRS score were separately (3.91 ± 0.88),(5.29 ± 1.25),(5.37 ± 1.30);VAS score and NRS score of group A were signifi cantly lower than group B,C and before treatment,with statistical significance (P＜0.05);PSQI score of group A,B,C were separately(4.03 ± 0.85),(5.92 ± 1.16),(5.83 ± 1.11);SF-36 score were separately (372.84 ± 73.25),(348.07 ± 60.54),(345.67 ± 59.72);PSQI score and SF-36 score of group A were significantly better than group B,C and before treatment,with statistical sig nificance (P＜0.05).There was no statistical significance in the incidence of ADR among 3 groups (P＞0.05).CONCLUSIONS:Compared with pregabalin and gabapentin alone,pregabalin combined with gabapentin in the treatment of central pain after cerebral infarction can efficiently relieve the perceived pain,improve sleep quality and daily life quality and not increase the risk of ADR;therefore,drug combination plan is recommended for patient with central pain after cerebral infarction,especially with poor effect of two single drug.

BACKGROUND:At present, a heparin-coated extracorporeal circulation pipe is used widely, but the price is expensive and limits its wide application.
OBJECTIVE:To screen the optimal coating condition of oxidated sodium alginate as a coating material to coat the medical polyvinyl chloride pipe and to evaluate the anticoagulant properties and the stability of the coated pipe.
METHODS:Oxidized sodium alginate was prepared with sodium periodate, and the mole ratio of sodium periodate and sodium alginate was 1:8, 1:10 and 1:12, respectively. Oxidized sodium alginate with different
degree of oxidation was coated on the surface of medical polyvinyl chloride pipes by chemical methods, then to select the best degree of oxidation. The optimal coating condition was screened through an orthogonal
experiment based on concentrations of sulfuric acid, polyethyleneimine and oxidized sodium alginate, and pH
value and temperature of oxidized sodium alginate. Additional y, the anticoagulant properties and expulsion rates of the prepared pipes were evaluated in comparison with the blank control group and heparin-coated group.
RESULTS AND CONCLUSION:The optimal oxidation degree for oxidized sodium alginate was 1:10 for the mole ratio of sodium periodate and sodium alginate. The best coating conditions were 50%concentrated sulfuric acid, 0.05%polyethyleneimine, 40 ℃ of reaction temperature, 2 g/L oxidized sodium alginate, and pH value=3.5. The oxidized sodium alginate coating group had a similar trend compared with heparin-coated group in the expulsion rate. The anticoagulant properties of oxidized sodium alginate coating group were little weaker than those of
heparin-coated group (P<0.05), but significantly better than those of the blank control group. The oxidized sodium alginate-coated extracorporeal circulation pipe has a good anticoagulant property and stability.
