Objective To study the diagnosis and therapy of Hashimoto's disease (HD) with thyroid nodule. Methods The clinical data of 187 patients with nodulous Hashimoto's disease who had operation in our hospital from 1995 to 2008 were analysed retrospectively. Results The nodules coexisting with Hashimoto's disease were thyroid carcinoma, nodular goiter, thyroid follicular adenoma and lymphoma accounting for 11.2% (21/187), 26.7% (50/187), 15% (28/187) and 1.6% (3/187) respectively. Conclusions HD patients with thyroid nodules especially the single nodule that can not be distinguished from cancer should have operation in time. Ultrasound guided needle aspiration will be helpful for the preoperative diagnosis and the frozen section may guide the surgical modality.

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.

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.

Aim To explore the effect of sesquiterpene lactone parthenolide(PL) on primary multiple myeloma(MM) cell and cell lines and its molecular mechanisms.Methods Fresh bone marrow cells from MM patients and MM cell lines KMM-1 and MM1S were used for in vitro culture study.The cell survival rate was examined by Trypan Blue exclusion.The change of nucleolus stained with DAPI was observed under fluorescent microscope.Reactive oxygen species(ROS) levels and mitochondrial membrane potential(MMP) were detected by flow cytometry.Results 2.5 ?mol?L-1 PL induced MM cell apoptosis and MMP was profoundly decreased in KMM-1 and MM1S cells.In contrast,normal lymphocytes cells were unaffected by the same conditions.KMM-1 and MM1S cells showed large increases of ROS levels 10 h after 2.5 ?mol?L-1 PL treatment.The free radical scavenger L-N-acetylcystein(L-NAC) pretreatment completely inhibited ROS generation,cell death and nuclear fragmentation by PL.Diphenylene iodonium chloride(DPI) pretreatment in a dose of 2.5 ?mol?L-1 strongly inhibited PL-mediated ROS generation,nuclear fragmentation in KMM-1 and MM1S cells.Conclusions PL strongly induces apoptosis in MM cell,while normal lymphocytes cells are completely unaffected by the same conditions.Since its proapoptotic activity appears to be mediated through induction of oxidative stress in MM cells,its possible mechanism is that NADPH oxidase activation is involved in PL-mediated ROS generation.

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

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.
