Objective To analyze the effect on prostate cancer bone metastasis of Uygur and Han people treated with strontium-89-chlovide.Methods The curative effects in 36 cases of Uygur and 40 cases of Han patients with prostate cancer bone metastasis were investigated after intravenous injection with strontium-89-chloride,including palliation of pain,change of metastatic focus,level of prostate-specific antigen (PSA) and interleukin-6 (IL-6).Results After treated with strontium-89-chlovide,compared with the han patients with prostate cancer bone metastasis,the palliation rate (83.33 ％) F-PSA [(29.29 ± 8.69) μg/L] and T-PSA [(3.73 ± 1.48) ml/L] were higher,the bone metastases and the level of IL-6 were more significantly reduced of Uygur patients,and there were statistically significant (x2 =4.113,t =1.359,t =1.849,all P ＜ 0.05).Conclusion It is more effective treated with 89 SrCl-chloride for the Uygur patients with prostate cancer bone metastasis metastases than the Han patients.

Objective To study the effect of Neuregulin-1 (NRG) on rat heart failure(HF) after myocardial infarction,and to investigate the underlying mechanism involving in NRG-mediated cardioprotection.Methods 60 adult Wister rats underwent sham operation (n=12) or coronary ligation (n=48) to induce HF.Four weeks after ligation,28 animals with HF were randomly divided into NRG group (rats received rhNRG-1 10 μg · kg-1 · d-1 intravenously for 10 days) or HF group (rats received an equal volume of water intravenously for 10 days).Left ventricular function was detected by echocardiography.Mitochondrial ultrastructure in non-infarcted myocardium was observed by transmission electronic microscopy.Cell apoptosis was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay.Mitochondrial membrane potential was measured by immunofluorescence method.Caspase-3 activity was determined by commercial kit.The expression of cytochrome C protein in cytoplasm was detected by Western blot.Results Compared with HF group,the left ventricular end-systolic diameter was decreased,and left ventricular ejection fraction and fractional shortening were increased in NRG group (P＜0.05 or 0.01).Apoptosis index was reduced inNRG group as compared with HFgroup [(18.1±3.0)％ vs.(11.9±1.4)％,P＜0.01].Mitochondrial membrane potential was increased and the release of cytochrome c in cytoplasm was reduced in NRG group as compared with HF group [(249.8±7.4) mV vs.(222.2±7.5) mV,(0.356±0.024) vs.(0.664±0.085),both P＜0.01].Caspase-3 activity was decreased in NRG group as compared with HF group (P＜0.01).Conclusions NRG attenuats mitochondrial stress and inhibits myocardial cells apoptosis in heart failure rats after myocardial infarction,which may play an important role in the cardioprotection by NRG.

BACKGROUND: Type Ⅰ collagen is a specific collagen secreted by in vitro cultured osteoblast, and the formed network is the basis of bone mineralization, which also reflects the ability of osteoblast bone formation. Studies have shown astragalus root increased osteoblast proliferation. However, the effect of astragalus root on improving type Ⅰ collagen expression of osteoblast remains poorly understood.OBJECTIVE: To evaluate the effect of astragalus root injection on the abilities of rat cranium-derived osteoblast proliferation and type Ⅰ collagen expression.METHODS: Rat osteoblast was cultured in vitro and divided into control group (MEM culture solution containing calf serum) and astragalus root groups (different concentrations). The effect on osteoblast proliferation was evaluated on days 1, 3, 5, 7, and 9 by MTT method. Moreover, the expression of type Ⅰ collagen protein was observed after 6 hours of treatment with astragalus root injection using in cell western-blot method. In addition, the gene expression of COLLal was investigated by real-time PCR method.RESULTS AND CONCLUSION: From days 3 to 9, the different concentrations of astragalus root injection improved osteoblast proliferation, respectively compared with control group (P ＜ 0.05), and this ascending trend peaked on day 7. Different concentretions of astragalus root injection improved COLLol mRNA expression, especially 15% astragalus root injection was the most effective. The type Ⅰ collagen protein expression of 15% and 10% astragalus root injection were significantly greater compared with the control group (P ＜ 0.05). Astragalus root injection improved in vitro cultured osteoblast proliferation and type Ⅰ collagen secretion in a certain dose-effect manner.

BACKGROUND:Bisphosphonates that can increase bone density and inhibit bone resorption have been clinical y confirmed, but the structure of the bone matrix has been less studied.
OBJECTIVE:To observe the effects of alendronate on bone structure and bone matrix metabolism, and then to investigate the control ing mechanism by which alendronate improves bone mass and increase bone intensity.
METHODS:An ovariectomized rat model was prepared and intervened with alendronate as treatment group. Model and sham-surgery groups were set as controls. Alendronate effects on bone mineral density, bone metabolism, bone biomechanics, and bone structure were observed in bone loss rats using bone imaging, bone tissue pathology and biomechanical test and enzyme-linked immunosorbent assay.
RESULTS AND CONCLUSION:Alendronate intervention could fight against bone loss as compared with model group at weeks 4, 8, and 12 after treatment (P<0.05). Compared with the model group, the expression of urinary deoxypyridinoline and serum carboxyterminal propeptide of type Ⅰ procol agen was decreased significantly after alendronate intervention (P<0.05);the maximal load, maximal pressure and modelus on the lumbar vertebrae and femur were increased as wel as ratio of urinary pyridinoline/deoxypyridinoline of type Ⅰ procol agen (P<0.05). These findings suggest that alendronate intervention can inhibit bone loss in rats induced by estrogen deficiency, increase biomechanical properties, improve bone matrix structure, and meanwhile, recover the Ⅰ col agen crosslinking component due to ovariectomy.

Objective: To compare the efficacy and side effects of patient-controlled intravenous morphine with epidural single bolus morphine in postoperative pain relief. Method: Sixty patients undergoing gynecological procedures under epidural anesthesia were randomly assigned to epidural morphine(EPI)group or patient-controlled intravenous analgesia (PCIA) group. In the EPI group,2 mg of morphine was injected into epidural space at the end of operation. In PCIA group, 1 mg of morphine as a demand dose would be injected intravenously by the patient through a patientcontrolled analgesic delivery system until the pain relieved. The patients were followed up at 4, 8, 12, 24 h after operation,and the degree of pain,sedation, nausea and vomiting were assessed. Result: The total dosage of morphine was higher in the PCIA group(19.08?5.0 mg)than that in the EPI group(2mg,P

Objective:To explore the mediating effect of empathy ability between personality characteristics and humanistic care ability of nursing undergraduates.Methods:The convenient sampling method was adopted to select 490 nursing undergraduates from the freshman to senior year of school of nursing in a medical university from June to July 2019 as the research objects. General information questionnaire, Caring Ability Inventory (CAI) , the Jefferson Scale of Physi-cian Empathy-Nursing Student (JSPE-NS) and Eysenck Personality Questionnaire-Revised Short Scale Chinese (EPQ-RSC) were used to conduct the questionnaire survey. A total of 490 questionnaires were issued and 435 valid questionnaires were recovered.Results:CAI score of 435 nursing undergraduates was (184.38±19.49) . The results of Sobel-test showed that the empathy ability of nursing students had a partial mediating effect between extroversion and neurotic personality characteristics and humanistic care ability, with effect values of 16.0% and 23.0%, respectively.Conclusions:The humanistic care ability of nursing students is at a low level, and the empathy ability plays a part of mediating role among the extroversion and neurotic personality characteristics and humanistic care ability of nursing undergraduates. Nursing educators can change the influence of extroversion and neurotic personality characteristics on the humanistic care ability by improving the empathy of nursing students, thereby improving the humanistic care ability of nursing undergraduates.
