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.

BACKGROUND:Previous studies have applied long-bone mechanical separation method to obtain osteoclasts, which are terminal y differentiated cells and cannot further proliferate. Therefore a large number of osteoclasts can be harvested with bone marrow cells inducing culture method and RAW264.7 cells inducing culture method to meet clinical requirements.
OBJECTIVE:To investigate the optimal method of receptor activator of nuclear factor kappa-B ligand (RANKL) induced osteoclast precursors to differentiate into mature osteoclasts.
METHODS:After bone marrow cells were isolated from mouse, RANKL and macrophage colony stimulating factor were added into the medium together, or RAW264.7 cells were cultured with RANKL to induce osteoclasts. The osteoclast precursors were treated with different concentrations of RANKL to observe the number of generated osteoclasts and evaluate the dose-effect relationship between RANKL and osteoclastogenesis. Annexin V-FITC and propidium iodide staining were used for flow cytometry to analyze the mononuclear-macrophage apoptosis during osteoclastogenesis.
RESULTS AND CONCLUSION:When 10μg/L RANKL was used, the peak of osteoclastogenesis appeared at days 6-7;when the concentration of RANKL was up to 100μg/L, the peak appeared at days 4-5. The number of new osteoclasts was dose-dependent on the RANKL concentration. 50μg/L of RANKL was the turning point in the fitted curve from osteoclastogenesis and RANKL concentration. After the RANKL concentration was more than 150μg/L, the number of osteoclasts slowed down obviously. RANKL can induce monocyte-macrophage to form osteoclasts and promote monocyte-macrophage apoptosis. The highest number of osteoclasts would be obtained to each unit of RANKL when monocyte-macrophage cells were cultured with 30μg/L of RANKL in the same vaccination density (104/cm2). Experimental findings indicate that, RAW264.7 cells or bone marrow cells inducing culture methods are simple and feasible, the optimum cellseeding density was 104/cm2;the appropriate stimulation concentration of RANKL was 30-50μg/L.

ObjectiveTo determine the effect of telmisartan on the levels of serum adiponectin and C-reactive protein(hs-CRP)in elderly hypertensive patients with unstable angina pectoris. MethodsOne hundred and twenty elderly hypertensive patients with unstable angina pectoris were randomized into two groups, telmisartan(n=60) and perindopril(n=60) groups.The levels of hs-CRP,adiponectin, lipid factors, fasting plasma glucose (FPG), insulin and insulin sensitivity index (ISI) were measured before and 6 months after telmisartan and perindopril treatments.ResultsAt the end of 6 months, the telmisartan group showed more reduction in plasma levels of hs-CRP and more increment in serum adiponectin concentrations and ISI significantly. The frequency of cardiovascular events was significantly lower in the patients of the telmisartan group than that of the perindopril group.ConclusionsCompared with perindopril, telmisartan significantly decreases plasma levels of hs-CRP and increases serum adiponectin concentrations in elderly hypertensive patients with unstable angina pectoris. It also significantly decreases the frequency of cardiovascular events in these patients.

Objective To investigate the mechanism by which remifentanil decreases blood pressure during cardiopulmonary bypass (CPB).Methode Twenty-six ASA Ⅱ or Ⅲ patients (NYHA's classification grade Ⅱ or Ⅲ ) of both sexes and aged 20-55 years were randomized to receive remifentanil (group R, n = 13) or normal saline (group C, n = 13). Remifentanil 10 μg/kg or equal volume of normal saline was administered via a venous reservoir when cardiac arrest was induced with cardioplegic solution. The flow rate resistance (SVR) were measured and arterial blood samples were taken for determination of plasma concentrations of histamine,nitric oxide (NO) and 6-keta-prostaglandin F1α(PGF1α) before T0 and at 5, 10, 15 min (T5.10.15) after remifentanil administration.Results Remifentanil administration was associated with a significant decrease in MAP and SVR at T5 and T10 as compared with the baseline values at T0 ( P ＜ 0.05); whereas in control group, MAP and SVR were significantly increased at T5, T10 and T15 as compared with the baseline values at T0 . There were no significant differences in plasma histamine, NO and PGF1α concentrations between the two groups.Conclusion Remifentanil reduces SVR and causes a decrease in BP but without altering plasma concentrations of histamine, NO or PGl2.

Objiective To evaluate the histocompatibility of gelatin-bletilla/Salvia-miltiorrhiza i material and to discuss the appropriate concentration of salvia-miltiorrhiza in the material. Method Salvia-miltiorrhiza together with gelatin and bletilla was used to make a kind of porous membranes. A total of 175 rats were divided randomly (random number) into 5 groups ( n = 35 in each). The porous membranes containing salvia-miltiorrhiza material in different concentrations of 1, 2, 4, and 5 mL/100 g were implanted subcutaneously into the rats of the four experimental groups, respectively. The gelatin-bletilla material without salvia-miltiorrhiza was implanted into the rats of control group. In 1, 3, 7, 14, 21, 28 and 56 days after implant, the materials were taken out of the bodies of the rats, separately. The material implanted for 1, 3, 7 and 14 days were observed with immunohistoche-mistry. Results In the area of implant, no noticeable inflammation or other was found. The implanted materials were degraded and entirely absorbed in vivo in 8 weeks. The salvia-miltiorrhiza in concentration of 2 mL/100 g in vivo promoted the angiogenesis most significantly. Conclusions The gelatin-bletilla/salvia-miltiorrhiza material has excellent histocompatibility and the appropriate concentration of salvia-miltiorrhiza in material is 2 mL/100 g.

Objective To evaluate the accuracy of auditory evoked potential index (AAI) in monitoring the anesthetic depth during isoflurane anesthesia.Methods Thirty ASA Ⅰ or Ⅱ patients aged 18-55 years and undergoing elective surgery under general anesthesia were enrolled in this study. The patients were unpremedicated. Anesthesia was induced with midazolam 0.05 mg/kg, fentanyl 3 μg/kg and propofol 1 mg/kg. Tracheal intubation was facilitated with recuronium 0.1 mg/kg. The patients were mechanically ventilated (VT:40 mm Hg. Anesthesia was maintained with isoflurane inhalation and intermittent intravenous boluses of vecuronium. Isoflurane was started with high-flow (FGF, 3 L/min) for 12 min followed by low-flow (LGF, 0.5 L/min). The inspired isoflurane concentration was set at 3%. The electrocardiogram (ECG), mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2), end-tidal isoflurane concentration and AAI were continuously monitored during anesthesia and recorded before induction of anesthesia (baseline, To ), immediately after induction (T1), immediately before isoflurane inhalation (T2), at 3 min(T3), 6 min (T4), 9 min (T5) and 12 min (T6) during high-flow wash-in and at the end-tidal isoflurane concentrations of 0.8 MAC (T7), 1.0 MAC (T8) and 1.3 MAC (T9) during low-flow inhalation of isoflurane, respectively.Results AAI decreased gradually while the end-tidal isoflurane concentration increased during high-flow wash-in. And AAI was negatively correlated with the end-tidal isoflurane concentrations ( r = -0.896, P ＜ 0.01 ) during low-flow inhalation of isoflurane anesthesia.
