From the perspective of hospice care， focusing on the entire process before and after the occurrence of a death event， taking the interpretation of the concept of death value in hospice care as the starting point， this paper explored the value connotation implied in the process of death from the perspectives of the terminal person， caregivers， and social culture， as well as summarized the characteristics of the death value. Meanwhile， in the current social context of the difficulty in achieving good death due to the shallow understanding of death， this paper analyzed the great significance of the construction of the death value concept in hospice care for improving the personal death quality of the terminal person， promoting the quality of end-of-life， and accelerating the formation of a social environment of good death， with a view to stimulating academic attention to the construction of the death value of terminal person， and providing conceptual reference for improving the quality of hospice care services.

Focusing on the field of palliative care，the Rodgers evolutionary concept analysis method was used to analyze the literature related to good death in the context of Chinese culture.The development history and application，definition and characteristics，influencing factors and their impacts，measuring indicators and tools of the concept of good death were elaborated，and further discussions were conducted.Good death refers to an individual’s peaceful and painless journey towards death，without subjective pain or concern，and calmness under the premise of sufficient longevity，while receiving care and companionship during the process of death from family，especially children and grandchildren，as well as achieving moral fulfilment and transcendence.The characteristics of good death in the context of Chinese traditional culture include the indirect expression of physical and mental pain being “understood” and properly handled，the construction of dying dignity based on virtue rather than autonomy，the emphasis on filial piety and emotional connections in the family，making after-death arrangements and realizing intergenerational inheritance，as well as the emphasis on achieving the integrity of life at the moment of death，which have distinct Chinese cultural characteristics.In the future，the connotation and extension of the concept of good death should be further explored，so as to assist in the development of localized theory and practice systems of good death.

Objective:To investigate the correlation between the location and volume of cerebral microbleeds (CMBs) and lacunar infarction (LI) in patients with cerebral small vessel disease (CSVD).Methods:Participants from the CSVD cohort in the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from February 2017 to March 2019 were enrolled retrospectively. All participants underwent magnetic resonance imaging scans, standardized clinical assessment and diagnosis. AccuBrain, an automatic brain segmentation and quantification software developed by the Chinese University of Hong Kong, was used to quantitatively analyze the volume of CMBs and white matter hyperintensities (WMHs). Ordered multi-class logistic regression analysis was used to determine the independent influencing factors of LI, and then multiple linear regression analysis was used to investigate the correlation between the volume of deep or infratentorial CMBs (DI-CMBs) and the number of LI. Results:A total of 317 patients with CSVD were included in the analysis, including 214 (67.5%) in the non-LI group, 43 (13.6%) in the single LI group, and 60 (18.9%) in the multiple LI group. The comparison of the three groups showed that older age, male, smoking, drinking, history of previous stroke or transient ischemic attack (TIA), lower levels of high-density lipoprotein cholesterol, larger CMBs and WMHs volume, higher enlarged perivascular spaces (EPVS) grade might be the risk factors for LI. Ordinal multivariable logistic regression analysis showed that male (odds ratio [ OR] 2.058, 95% confidence interval [ CI] 1.084-3.909; P=0.027), previous stroke or TIA history ( OR 1.962, 95% CI 1.089-3.535; P=0.025), larger WMH volume ( OR 8.716, 95% CI 4.034-18.832; P<0.001), higher EPVS grade ( OR 1.915, 95% CI 1.292-2.839; P=0.001), larger DI-CMB volume ( OR 1.022, 95% CI 1.006-1.038; P=0.008) or more DI-CMB number ( OR 1.187, 95% CI 1.005-1.403; P=0.044) were the independent related factors of LI. Multiple linear regression analysis showed that there was a significant correlation between the volume of DI-CMB and the number of LI ( r=0.330, P<0.001). Conclusion:In patients with CSVD, there is a significant correlation between DI-CMBs and LI.

Objective:To compare the early efficacy of direct anterior approach versus posterolateral approach for total hip arthroplasty in elderly patients.Methods:The 48 elderly patients receiving total hip arthroplasty from September 2017 to September 2019 were divided into two groups: DAA group(n=23, 30 hips)receiving direct anterior approach for total hip arthroplasty, and PLA group(n=25, 33 hips)receiving posterolateral approach for total hip arthroplasty in this retrospective study.The operation time, blood loss, length of hospital stay, acetabular abduction angle, anteversion angle, and intraoperative and postoperative complications were recorded and compared between the two groups.The hip function was compared with Visual Analogue Scale(VAS)and Harris Hip Score(HHS).Results:All the 48 patients were followed up for 7-31 months, with an average of 22.8 months in DAA group, and 24 months in PLA group.The operation time was less in PLA group than in DAA group[(49.3±5.7)min vs.(70.3±6.2)min, t=12.22, P=0.00], while the hospital stay was longer in PLA group than in DAA group, with a statistically significant difference[(7.8±1.5)d vs.(5.6±1.3)d, t=-5.40, P=0.00]. There was no significant difference in intraoperative blood loss between the two groups[(173.1±47.9)ml vs.(189.6±48.7)ml, t=1.18, P=0.24]. The VAS and HHS scores were better at 1 month after operation and at the last follow-up than before operation in both DAA and PLA group(all P<0.05). The VAS and HHS scores were better in DAA than in PLA groups( P<0.05)at 1 month after surgery.However, at the last follow-up, there was no significant difference in VAS and HHS scores between the two groups( P>0.05). Conclusions:The early results of direct anterior approach for total hip arthroplasty are satisfactory in patients aged 85 years and older.It has the advantages of less trauma, faster postoperative recovery and shorter hospital stay.

Objective:To objectively evaluate the therapeutic effect of Chinese cupping therapy.Method:Near-infrared spectroscopy (NIRS) was used to evaluate the concentration change in oxygenated hemoglobin ([HbO 2]), deoxy-hemoglobin ([Hb]) and blood volume ([tHb]) in 13 healthy volunteers during cupping therapy for the infraspinatus muscle. Results:During the cupping therapy and its pre- and post-treatment period, it was observed that [Hb] and [tHb] in the tissue surrounding the cupping site decreased significantly (both P<0.05), and [HbO 2] increased significantly ( P<0.05), which showed an increase in oxygen uptake. After the cupping was removed, the above hemodynamic changes could still continue for a period of time. Conclusions:Cupping therapy has potential positive therapeutic effects in promoting the hemodynamics for facilitating muscular functions. Functional NIRS surgery has great application potential in the field of physical rehabilitation therapy such as cupping.
