AIM: To investigate whether focal adhesion kinase (FAK) takes part in the intracellular signaling pathway involved in apoptosis of human pulmonary artery smooth muscle cells (HPASMCs). METHODS: Cultured HPASMCs stimulated by fibronection (40 mg/L) were passively transfected with antisense-FAK oligodeoxynucleotides (ODNs). Expression of FAK and caspase-3 proteins was detected by immunoprecipitation and Western blotting. In addition, apoptosis were measured by TUNEL. RESULTS: The protein expression of FAK in HPASMCs decreased and caspase-3 expression upregulated in HPASMCs in antisense-FAK ODNs group. At the same time, antisense-FAK ODNs transfection increased the rate of cell apoptosis. CONCLUSION: These results suggest that FAK may be related with the apoptosis of HPASMCs. Antisense-FAK ODNs inhibit HPASMC proliferation and may facilitate their apoptosis via caspase-3 signaling pathway.

Objective To investigate the training effect and application development of the health industry standard of Nursing Grading, and to explore it'sclinical applicability. Methods An electronic questionnaire survey was conducted among nurses in 30 three general hospitals of Shandong Province from November 10 to December 10 in 2015. The questionnaire mainly included four parts: basic information, training status, application status and the clinical applicability. All the questionnaires were automatically submitted by the nurse′s cell phone or computer, 3386 valid questionnaires were recovered. Results The status of standard training:93.92%(3180/3386) nurses received a comprehensive training about the standard. The answer rates of 4 theoretical examination questions was 88.95%(3012/3386), 84.49%(2861/3386), 85.17%(2884/3386), 65.71%(2225/3386)respectively. 77.26%of the nurses needed to continue training. Application status: 97.67% (3307/3386) nurses in the hospital has begun to apply Nursing Grading standard, and 97.01% (3208/3307) and 97.76% (3231/3307) of the hospital revised the standard of care systems and work processes; 78.23% (2649/3386) nurses divide the level of care based on both the patient's condition and self-care ability presently. 74.45%(2521/3386) nurses did it as follows,the doctor determine the patient′s condition level, the nurse determine the level of patient′s self-care ability, then the nursing grading was determined according to the both. In the clinical applicability survey, the choice proportion of very agree and agreeofHelping nurses to determine the patient′s level of care and It is beneficial to improve the efficiency of nursing management was 86.30% (2922/3386) and 82.66%(2799/3386);The choice proportion of very agree and agree ofHelp nurses to improve the quality of nursing services, reflecting the value of the nursing work, to meet the needs of patients was 79.36% (2687/3386), 76.56% (2592/3386), 80.98% (2742/3386) respectively. Conclusions The hospital attaches great importance to the standard of Nursing Grading, but the training effect needs to be improved;standard has been widely used in Shandong Province Physician-nurse collaboration has become the decision-making main body of nursing grading;the standard application can not only help the nurses to do decision-making correctly and improve the efficiency. It also can help nurses to improve the quality of nursing service, and enhance patients′satisfaction. So it is very suitable for clinical practice.

Objective To investigate the intervention effect of motivational interviewing health education based on trans-theoretical model to hospitalized patients with cerebral infarction on their healthy diet cognition and behavior change.Methods 60 patients with cerebral infarction were selected with convenient sampling method,and in accordance with the incorporating order randomly divided them into the intervention group and the control group,each with 30 cases.The intervention group received the motivational interviewing health education based on the trans-theoretical model,which mainly focused on a healthy diet,while the control group received regular health diet education.The intervention effect was compared between two groups.Results The comparative difference of baseline data between the two groups before intervention had no statistical significance,while after intervention the change on knowledge and attitude of these two groups both had statistical significance,but the intervention group improved more obviously than the control group; In regards to behavior change phrase,comparing the healthy eating behavior phase of the intervention group patients before and after the intervention,it was found that before the intervention only 4 cases were on the stage of about-to-change,accounting for 13.3％,but after the intervention the proportion was up to 40.0％ with 12 cases.Using chi-square test to compare the behavior phrase difference of the patients before and after the intervention,the difference was statistically significant.Conclusions Motivational interviewing technique based on the trans-theoretical model is an effective method in terms of cognitive and behavioral change,and the health education will improve the cognition on healthy diet and the behavior of the hospitalized patients with cerebral infarction.

To investigate the effect of cigarette smoke extract (CSE) on the role of protein kinase C (PKC) in the proliferation of passively sensitized human airway smooth muscle cells (HASMCs). After synchronization of cultured HASMCs, they were divided into a group A and Group B. The group A was treated with normal human serum and served as controls and the group B was treated with the serum of asthma patients. The group A was further divided into group of A1, A2 and A3 and the group B was sub-divided into the group of B1, B2, B3, B4 and B5. No other agents were added to the group A1 and B1. The cells of group A2 and B2 were stimulated with 5% CSE for 24 h. HASMCs from group A3 and B3 were treated with PKC agonist PMA (10 nmol/L) and CSE (5%) for 24 h. PKC inhibitor Ro-31-8220 (5 micromol/L) was added to the HASMCs of group B4 for 24 h. The cells from group B5 were stimulated with Ro-31-8220 (5 micromol/L) and CSE (5 %) for 24 h. The proliferation of HASMCs isolated from group A and B was examined by cell cycle analysis, MTT colorimetric assay and 3H-TdR incorporation test. The expression of PKC-a in each group was observed by Western blotting and RT-PCR, respectively. The results showed that the percentage of S phase, absorbance (A) value, the rate of 3H-TdR incorporation, the ratios of A value of PKC-alpha mRNA and the A value of PKC-alpha protein in HASMCs from group B1, B2 and B3 were significantly increased compared to those of group A1, A2 and A3 correspondingly and respectively (P< 0.01). The proliferation of HASMCs of group A2 and B2 stimulated with CSE and group A3 and B3 stimulated with CSE and PMA were also significantly enhanced when group A1, A2 and A3 and group B1, B2 and B3 compared to each other (P<0.05, P<0.01, respectively). The percentage of S phase, absorbency (A) value, 3H-TdR incorporation rate, the ratios of A value of PKC-alpha mRNA and the A value of PKC-alpha protein in HASMCs from group B4 treated with Ro-31-8220 and group B5 treated with CSE and Ro-31-8220 were significantly decreased as compared to those of group B1 and B2 correspondingly and respectively (P<0.05, P<0.01). It was concluded that CSE can enhance the passively sensitized HASMC proliferation and the expression of PKC alpha. PKC and its alpha subtype may contribute to this process. Our results suggest cigarette may play an important role in ASMCs proliferation of asthma through PKC signal pathway.

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a kind of targeted drug for the treatment of non-small cell lung cancer (NSCLC),but almost all patients develop EGFR-TKI resistance.In Chinese medicine,it is believed that Yang deficiency is the leading cause of tumor,which could end up with the internal formation of cancer toxin and promote the formation of tangible excess pathogens.Clinical and experimental studies have shown that the Chinese medicine treatment based on Yang-warming method can inhibit EGFR-TKI resistance and improve the therapeutic effect of EGFR-TKI.The mechanism may be related to the regulation of miRNA gene and estrogen receptor expression,being against tumor heterogeneity and the regulation of tumor microenvironment.Therefore,Yang deficiency is the key pathogenesis of the EGFR-TKI resistance in NSCLC,and the method reinforcing Yang and suppressing Yin is the basic therapeutic way in Chinese medicine to overcome EGFR-TKI resistance.
