The theory of multiple streams,a vehicle of public policy analysis in the West,was used to analyze the policy development at Beijing′s suburban village clinics.This approach can clarify the issue steams,policy streams,and political streams,as well as the links between them,as a reference for standardized and quickened development such clinics.

In the early 20th century,the term Nursing was introduced into China.In 1884,with the arrival of the first batch of missionary nurse,modern nursing initiated by Nightingale was introduced into China and greatly changed the way of care.The missionary nurses were full of enthusiasm for the spreading Gospel of Christ,the love for nursing care and the empathy for Chinese people;and encountered the lack of staff and material,the mis-understanding and resistance from the local people and other multiple tests.With the untiring effort of them and the trained local nurses,China had led the international care in nursing education and practice standard.Based on this,nursing in Shandong gradually rose and had an unprecedented development as a new medical subject.By clearing up and consulting Chinese and English historical materials,this paper reviewed the 60 years of the mission-ary nurses in China,saw the early development of nursing in our country from the budding and development of Shandong nursing and provided more insights for understanding and solving the complex problems contemporary Chinese nursing faces.

The performance appraisal (PA) system establishment in scientific research institutes on traditional Chi-nese medicine (TCM) plays an important role in the management of TCM research work, which can set up both well-defined guidance and favorable appraisal regimen for scientific researchers, so that leads to the accomplishment of the scientific objectives. However, current PA system establishment has fallen seriously behind the real demand in most TCM research institutes. As a result, there is a serious lack of a mature, efficient, standardized, propagable PA system in TCM research field. In this paper, we tried to discuss the current situation and key issues in building modern PA system in TCM research institutes. The PA system development in scientific research institutes on TCM was pointed out. The PA system should be based on existed referenced similar platforms, with full consideration on professional features and Chinese culture. The PA system establishment should be with most science, systematicness, objectivity, and guidance. The PA system should also be established to evaluate the scientific researchers equitably, guide the scientific trend, provide proper institute, and promote scientific research.

Objective To evaluate the sonographic features of testicular adrenal rests tumors in minor males. Methods The sonographic feature of pathologically or clinically confirmed testicular adrenal rests tumor in 13 minor males was retrospectively analyzed;we analyzed the number, morphology and size of affected testis; the involvement of testicular mediastinum; lesion location; the growth pattern, shape, boundaries, size, internal echo and blood supply of lesions. Results All of the 13 cases were bilateral and there were 26 lesions in all, 5 cases (5/13, 39%) had normal testicular size and morphology, testicular mediastinum were seen in 12 cases (12/13, 92%);26 (26/26, 100%) TARTs were all located near the testicular mediastinum or the testis hilar;21 (21/26, 81%) lesions had irregular shape while 5 (5/26, 19%) lesions were round;26 (26/26, 100%) lesions all had clear boundary but had no echo envelope;the lesion size was (1.5 ± 1.0) cm in average;13 (13/26 , 50%) lesions showed homogeneous hypoecho, 11 (11/26, 42%) lesions showed inhomogeneous hypoecho and 2 (2/26, 8%) lesions showed inhomogeneous isoecho; 19 (19/26,73%) lesions displayed rich blood supply and 7 (7/26, 27%) lesions displayed scarce blood supply. Conclusion The sonographic appearance of TART in minor males was characteristic, ultrasonography has important clinical value.

Objective To compare the expressions of Beclin 1 and its 11 interacting proteins in subcutaneous fat and visceral fat,and to observe the expressions of these genes in 3T3-L1 adipocytes differentiation process.Methods In 3T3-L1 adipocytes,cells were harvested at day 0,2,4,6,8 in differentiation process,and then proteins or mRNAs were obtained and followed with Western blot and realtime PCR.Mice tissue proteins or mRNAs were detected with Western blot and realtime PCR.Results In 3T3-L1 adipocytes differentiation process,expressions of LC3,Beclin 1,and TNFAIP3 continued to rise,expression of BIRC5 was high to low,FEZ1 continued at a low level.In mice,expressions of LC3,Beclin 1,YWHAQ,FEZI,BAD,WAC,TNFAIP3,and GOPC in visceral fat were significantly higher than those in subcutaneous fat,while expression of SLAMF1was higher in subcutaneous fat.Conclusion Autophagy plays an important role in 3T3-L1 differentiation process and may be tissue-specific in visceral fat and subcutaneous fat.

Dermatomyositis with malignancy is a subtype of dermatomyositis, and the concurrence of malignancy is a major factor for poor prognosis of dermatomyositis. Malignancy usually occurs within 1 year before or after the diagnosis of dermatomyositis. Compared with classic dermatomyositis, dermatomyositis with malignancy mostly occurs in patients aged>50 years, and is typically characterized by the heliotrope sign, skin necrosis and presence of myositis-specific antibodies such as anti-transcriptional intermediary factor-1γ and anti-nuclear matrix protein-2 antibodies, etc. Thorough screening for malignancy or close monitoring and follow-up are necessary in patients with dermatomyositis.

Objective To evaluate the ablation zone and temperature changes in the liver caused by laser ablation in vitro and in vivo.Methods Single needle single point laser ablation was performed in vitro with porcine liver using 5 W and 7 W-power and in vivo with rabbit liver using 5 W-power.All energy outputs were 1 800 J.The ablation zone and temperature changes were evaluated.Results Coagulation caused by laser ablation was divided into a black carbonized area and a brown white necrotic area from inside to out,respectively.The mean in vitro ablation range obtained by 5 W and 7 W-power laser ablation was 1.9 cm × 1.2 cm × 1.2 cm and 2.5 cm × 1.5 cm × 1.5 cm,respectively.The mean in vitro black carbonized range obtained by 5 W and 7 W-power laser ablation was 1.1 cm × 0.5 cm × 0.5 cm and 1.4 cm × 0.7 cm ×0.7 cm,respectively.The average maximum temperature using 5 W-power was 243.57 ℃,62.47 ℃ and 34.27 ℃ in the ablation center,5 mm from the center,and 10 mm from the center,respectively.For in vivo liver experimentation,the average maximum temperature using 5 W-power was 62.26 ℃ and 44.35 ℃5 mm and 10 mm from the center,respectively.Conclusion Laser ablation can cause coagulation necrosis of the liver tissue in vitro and in vivo,and the ablation range increased with increasing power.Laser ablation may have potential use in the ablation of tumor localized in critical sites.

The study found that the physician-patient trust crisis results from overreliance on technology trust instead of interpersonal trust and institutional trust. The alleged “Paternalistic government innovation”in healthcare service has caused wastes of healthcare resources and gap below public expectancy due to its incompetence in resolving social problems,further eroding institutional legality and intensifying such crisis.This research aimed to identify government accountabilities in building such trust from three aspects.

Objective To investigate the value of color Doppler flow imaging(CDFI) in diagnosing lower limb artery in-stent restenosis (ISR), and to provide the evidences for clinical application. Methods Patients with lower limb artery percutaneous transluminal stent insertion in 12 months were enrolled in this study and divided into two groups, CT angiography (CTA) or digital subtraction angiography (DSA) was applied to diagnose ISR, 31 patients with 47 stenting which were diagnosed ISR was named as restenosis group, 63 patients with 89 stenting which were diagnosed no ISR was named as no stenosis group, and 30 normal person was enrolled and named as normal control group. Ultrasonic characteristics and peak systolic blood flow velocity (PSV), systolic blood flow acceleration time (AT) of proximal part, inner stents, distal part were recorded in restenosis group and no stenosis group, then compared with data in normal control group. Regression and receiver operator (ROC) curve were applied to analyse the correlation between PSV and AT. Results PSV of no stenosis group in common femoral artery, femoral artery, superifcial, popliteal artery stent respectively were (146.71±35.59) cm/s, (120.11±25.67) cm/s, (96.44±32.87) cm/s. PSV of normal control group in common femoral artery, femoral artery, superifcial, popliteal artery respective were (119.67±15.34) cm/s, (91.17±15.09) cm/s, (71.13±21.23) cm/s. There was statistically signiifcant difference between the two groups (t=2.457, 2.459, 2.321, all P<0.05). AT of no stenosis group in common femoral artery, femoral artery, superficial, popliteal artery stent respectively were (84.98±13.77) ms, (87.33±16.36) ms, (90.77±12.05) ms. AT of normal control group in common femoral artery, femoral artery, superficial, popliteal artery respective were (78.23±21.24) ms, (82.31±18.24) ms, (84.29±23.01) ms. There was no statistically signiifcant difference between the two groups (t=1.696, 1.904, 1.835, all P>0.05). PSV of restenosis group in proximal part, restenosis part, distal part respectively were (87.67±23.34) cm/s, (218.17±72.09) cm/s, (54.13±21.23) cm/s. PSV of no stenosis group in proximal part, inner stents, distal part respectively were (91.71±25.59) cm/s, (131.11±45.67) cm/s, (96.44±32.87) cm/s. There was statistically significant difference between restenosis part/inner stents, distal part (t=3.412, 3.511, both P<0.05). There was no statistically signiifcant difference between the two groups in proximal part (t=1.901, P>0.05). AT of restenosis group in proximal part, restenosis part, distal part respectively were (98.31±14.09) ms, (109.54±21.03) ms, (158.23±45.21) ms. AT of no stenosis group in proximal part, inner stents, distal part respectively were (84.98±13.77) ms, (86.34±19.36) ms, (83.77±17.05) ms. There was statistically signiifcant difference between restenosis part/inner stents, distal part (t=2.319, 3.610, both P<0.05). There was no statistically signiifcant difference between the two groups in proximal part (t=1.833, P>0.05). ROC curve showed that in ISR lower limb artery, PSV>168 cm/s had a sensitivity of 89.4%, speciifcity of 92.1%, the area under the ROC curve was 0.949;AT>127 ms, had a sensitivity of 86.8%, speciifcity of 98.0%, the area under the ROC curve was 0.867. Conclusions CDFI can detect the changes of PSV and AT, ISR can be detected and diagnosed earlier in lower limb artery. By combining PSV>168 cm/s with AT>127 ms, the value of ISR diagnosis can be increased.
