Purpose To investigate the influence of single slow intravenous infusion of dexmedetomidine (Dex) on femoral artery color Doppler hemodynamics during the induction of general anesthesia. Materials and Methods Forty patients of elective abdominal surgery under general anesthesia were elected and randomly divided into Dex group and the control group, with 20 cases in each group. Dex (0.2 μg/kg) 20 ml was injected with intravenous infusion in Dex group, and 20 ml saline was infused in control group, the infusion time was 10 min;then intravenous injection of Sufentanil, Propofol and Rocuronium were performed in turn for the induction of general anesthesia and endotracheal intubation. Femoral artery peak systolic velocity (Vs), early diastolic reverse peak velocity (Vd), systolic diameter (Ds), diastolic diameter (Dd), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) changes at each time point were observed and recorded. Results ① Compared with baseline, Vs increased and Vd decreased (P<0.05) 10 min after the infusion of Dex in Dex group;after induction, Vs and Vd in both of the two groups decreased, and the difference between the two groups was not statistically significant (P>0.05);Vs reduced significantly in both of the two groups at the intubation moment and 1, 3, 5 min after intubation, but the Dex group changed more smoothly (P<0.05), and Vd raised in both groups with the Dex group changing more smoothly (P>0.05);Ds and Dd of both groups did not change significantly at each time point (P>0.05). ② Compared with baseline, MAP and HR decreased (P<0.05) after the infusion of Dex in Dex group;after induction, MAP and HR of both groups decreased, and the difference between the two groups was not statistically significant (P>0.05); MAP and HR increased in both groups at intubation moment, but the Dex group changed more smoothly than the control group (P<0.05).③SBP, DBP and HR were negatively correlated with Vs (r=-0.507,-0.619,-0.750, P<0.05) in both groups; SBP, DBP and HR were positively correlated with Vd (r=0.821, 0.881, 0.883, P<0.05) in both groups;there was no significant correlation (r=0.419, P>0.05) between Vs and Vd. Conclusion Single slow intravenous infusion of Dex (0.2μg/kg) can accelerate the femoral artery Vs and slow down the Vd, resulting in more stable hemodynamics during the induction of general anesthesia.

Objective To discuss repairing effects of articular cartilage defects by nitric oxide synthase inhibitor (S-methylisothiourea, SMT), and explore the role of nitric oxide in cartilage repair. Methods Full-thickness defects of cartilage were created in the intercondylar trochlear groove of femur of thirty-six adult New Zealand white rabbits, and were divided into three groups. Twenty-four defects were untreated as the control, twenty-four were filled with fibrin glue and impregnated with rhBMP as rhBMP group, the rest twenty-four were filled with fibrin glue and impregnated with rhBMP, and hypodermic injection with SMT as SMT group. The animals were sacrified at sixteen weeks postoperatively, and the gross appearance of the defect was estimated. The repair tissue was examined histologically and was evaluated according to the grading scale of histology. The amount of released NO and the activities of nitric oxide synthase (NOS) were examined by chemical colorimetry. The distribution of type-Ⅰ,Ⅱcollagen were examined by Sirius-Red. The proteoglycan synthesis was assessed by incorporation of radio-labelled sodium sulphate Na35SO42-. RT-PCR examined the expression of iNOSmRNA and MMP9mRNA. Results The filled extent of the defect in SMT group and rhBMP group had no significant difference from the control group, and the marginal integration, cellular morphology, architecture within the defect and subchondral plate repair were better than the untreated defects (P

Objective To investigate the efficacy and safety of intravitreous injection with triamcinolone acetonide (TA) for cystoid macular edema (CME) due to central retinal vein occlusion (CRVO). Methods Fourteen eyes of 14 patients with CME due to CRVO underwent intravitreous injection with 0.1 ml TA (40 mg/ml). Best-corrected visual acuity, intraocular pressure (IOP), slitlamp examination, fundus fluorescein angiography, and optical coherence tomography (OCT) were performed on the patients before and after the injection. The follow-up period was 10-22.4 months, with the mean of 15.9 months. Results The average visual acuity was 0.1 before the treatment; while 1 month and 3 months after the injection, the visual acuity of all of the patients improved, including ≥0.2 in 71.43% and 63.6% of the patients, respectively, and ≥0.5 in 42.9% and 27.3%, respectively. After then, the visual acuity of some patients decreased, and in the final visit, 4 eyes (28.6%) had a visual acuity of ≥0.2, and 1 eye (7.1%) of ≥0.5. Compared with that before the treatment, the visual acuity of 10 (71.4%) eyes improved and 4 (28.6%) eyes declined. One month after the treatment, the macular edema disappeared in 10 eyes (71.4%) and alleviated in 4 (28.6%). In the final visit, macular edema disappeared in 4 eyes, alleviated in 9, and aggravated in 1. In the follow-up duration, high IOP [22.3-40.1 mm Hg (1 mm Hg=0.133 kPa)]. In the final visit, posterior subcapsular cataract was found in 7 eyes. Conclusion Intravitreous injection with TA may be effective in reducing CME and enhancing the visual acuity in a short term with high IOP in some eyes. In the long-term follow-up period, the rate of recurrence of CME and incidence of posterior subcapsular cataract is high.

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 study the effect of nitric oxide synthase inhibitors S methylisothiorurea (SMT) on cartilage metabolism after intraarticular injection of interleukin 1? (IL 1?) and lipopolysaccharides (LPS) in rabbits.Methods The experiments were performed in three groups:normal group,control group and SMT group.The effects of SMT on IL 1? and LPS induced iNOS mRNA expression ,NO production and NOS activity in synovium,synovial fluid and cartilage were detected after 8 h.Proteoglycan synthesis was measured by ex vivo incorporation of Na 2 35 SO 4 into cartilage after 48 h.Results IL 1? and LPS induced iNOS mRNA expression and increased NO release;SMT could reduce NO release and inhibit iNOS mRNA expression in synovium,synovial fluid and cartilage,and partly restore proteoglycan synthesis of cartilage.Conclusion iNOS inhibitor SMT can protect IL 1? and LPS induced cartilage damage in high concentration.

Objective To study the long-term outcome of cardiac resynchronization therapy (CRT) in drug refractory heart failure patients through retrospective analysis and to ivestigate the underline reasons of unsuccessful cases in the study. Methods The study comprised a total of 48 patients (mean age 70?18.5 years; 83% male) with New York Heart Association class Ⅲ (86%) or class Ⅳ (14%) heart failure and LVEF≤35%. All patients fulfilled the standard CRT indications with the QRS duration ≥130 and LVEDd≥60 mm. Only one of the 48 patients was implanted with a combination of automatic implantable cardioverter-defibrillator and CRT device. The outcome of CRT was evaluated in terms of QRS duration, LVEF through echocardiography, 6 minute hall walk and tissue doppler echocardiography. Results Within a mean clinical follow-up of 29.0?7.5 month, the QRS duration was significantly shortened by biventricular pacing compared with right ventricular or left ventricular pacing. [(169?26) ms vs (188?40) ms and (222?34) ms vs (212?42) ms, respectively]. The NYHA functional class was improved from class Ⅲ-Ⅳ before the operation to class Ⅰ-Ⅱ at 1 week and 1 month during the follow up period. LVEF increased gradually from (28.30?3.94)% to (37.80?3.98)% after one week and increased to (42.99?7.87)% at the end of the follow-up. There was significant difference in LVEF before and 1 week after the operation (P
