This paper defines the implication of mutual love between doctors and patients,analyzes the tendency and imperfection in present physician-patient relationship,and points out that the mutual love between doctors and patients is the guarantee for a harmonious physician-patient relationship.It is not only a theoretical ideal,but also a practice of medical service.It holds to propose fair and initiative mutual love between doctors and patients in China,realize general love for all individuals by government,and strengthen the sense of love for others among all ranks of populations.

At present,the relationship between hospitals and patients is becoming increasingly tense,which makes feasible approaches of benignization of the relationship worthy of probing into.The sample survey shows that a doctor or a nurse who is able to win patients'trust should treat patients equally,respect patients'personality,enhance mutual understanding,regard patients as their relatives,possess noble professional morality and foster a nice individual image.

The reasons what the phenomenon of Hongbao exist are intricate and complex.The existence of the phenomenon of Hongbao blasphemes against the medical care justice,accelerate the relationship between hospital and patients tension.It will be a fact that the Chinese society unable to radical change in established period.We need to reduce the appearance of the phenomenon of Hongbao as many as possible,and prepare for eliminating the unreasonable and unjust social phenomenon finally.

Objective:To systematically evaluate the efficacy and safety of demethylation drugs intreatment of myelodysplastic syndrome (MDS), and to provide reliable basis and guidance for clinical application of these drugs.Methods:The randomized controlled trials (RCT) of demethylation drugs for treatment of MDS published in the PubMed, Web of Science, Embase, Cochrane Library, Chinese Journal Full-text Database (CNKI), Chinese Biomedical Literature Database (CBM) and VIP database from January 2000 to December 2019 were searched by computer. RevMan 5.3 software was used for Meta-analysis of the efficacy and safety.Results:Seven RCT studies involving 1 172 patients were obtained. Meta-analysis showed that the complete remission rate ( OR = 6.26, 95% CI 1.74-22.49, P = 0.005), partial remission rate ( OR = 4.65, 95% CI 1.51-14.29, P = 0.007), overall response rate ( OR = 14.14, 95% CI 7.27-27.51, P < 0.01), hematology improves ( OR = 3.47, 95% CI 1.44-8.32, P = 0.005) in the demethylation drug treatment group were better than those in the best supportive treatment group. Meanwhile, the overall survival of patients in azacytidine group was improved ( HR = 0.62, 95% CI 0.50-0.77, P < 0.01). In terms of adverse reactions, demethylation drugs increased the incidence of neutropenic fever ( OR = 4.19, 95% CI 2.26-7.76, P < 0.01). However, there was no significant difference in the incidence of neutropenia, thrombocytopenia, anemia, infection, nausea, liver damage and fatigue between the two groups (all P > 0.05). Conclusions:The effect of demethylation drugs in treatment of MDS is obvious, the remission rate can be improved, and azacytidine can prolong the patients' survival, but demethylation drugs increase the incidence of neutropenia fever. In the clinical application of demethylation drugs, it is necessary to further carefully evaluate their clinical safety.

Objective:To observe the effect of emotional resilience training on compassion fatigue and psychological resilience of intensive care unit nurses.Methods:A total of 70 intensive care unit nurses were randomly divided into experiment group and control group, each of 35 cases. Control group nurses were given routine psychological guidance intervention, in addition, the experiment group was carried out 8 weeks of emotional resilience training. The effect of intervention was assessed by Chinese version of the compassion fatigue scale and Connor-Davidson resilience scale before and after intervention.Results:After intervention, the average scores of compassion satisfaction, secondary traumatic stress and total compassion fatigue scores were (26.46±4.99)pionts, (17.80±4.05)pionts and (69.14±5.70)pionts, significantly lower than in the control group (28.86±4.14)pionts, (20.11±4.38)pionts and (75.51±10.32)pionts, the difference was statistically significant ( t value was 2.190, 2.296, 3.197, P<0.05). After intervention, the average scores of tenacity, power, optimism and total resilience scores were (34.23±6.06)pionts, (25.77±5.01)pionts, (14.31±3.22)pionts and (74.31±9.55)pionts, significantly higher than in the control group (30.86±6.23)pionts, (23.31±3.29)pionts, (12.11±2.04)pionts and (66.29±7.28)pionts, the difference was statistically significant ( t value was 2.295-3.956, P<0.05). Conclusion:Emotional resilience training can effectively reduce the compassion fatigue and improve psychological resilience of intensive care unit nurses.

BACKGROUND:Demineralized bone matrix as bone tissue engineering biological scaffold material is more researched currently, which has osteoinductive and osteoconductive.
OBTECTIVE:To summarize the development of demineralized bone matrix as bone tissue engineering scaffold material and to prospect its trend.
METHODS:The relative literatures addressing demineralized bone matrix as bone tissue engineering scaffold material published between January 1965 and May 2013 in PubMed database, Chinese Biomedical Database, Wanfang Database and FMJS database were searched by the first author. The key words were“demineralized bone matrix, scaffold material, growth factor, cells, drugs”in English and Chinese. According to the inclusion criteria, repetitive researches were excluded, and final y 34 articles were included.
RESULTS AND CONCLUSION:Scaffold material is the key composition of tissue engineered bone, and only demineralized bone matrix has both osteoinductive and osteoconductive properties which cannot only provide space for bone repair, but also can be combined with bioactive factors, living cells, antibiotics in vitro to construct bone graft thereby promoting healing of bone defects. However, this technique is also facing some problems to be solved such as the ratio of demineralized bone matrix and various substances, disinfection, preservation of osteogenetic activity and antigenicity elimination. Sufficiently understanding demineralized bone matrix as bone tissue engineering scaffold can provide a theoretical basis for its clinical service.

Objective To invetstigate the effects of right stellate ganglion block (SGB) on heart rate variability (HRV) in patients with carbon dioxide pneumoperitoneum.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 39-75 yr,weighing 47-75 kg,undergoing elective laparoscopic cholecystectomy,were randomly divided into 2 groups ( n =20 each):control group (group C) and right SGB group (group SGB).Right SGB was performed with 1％ lidocaine 7 ml at 10 min before induction of anesthesia.The low frequency power ( LF),high frequency power (HF),total power (TP) and LF/HF ratio were recorded before SGB (baseline,To ),at 5 and 30 min of pneumoperitoneum (T1,2),at 5 min after deflation (T3) and at the end of operation (T4 ).The LF in normalized units (LFnu) and HF in normalized units (HFnu) were calculated.Results Compared with the baseline values at T0,LF,LFnu and LF/HF ratio were significantly increased at T1-4,HF was significantly decreased at T3,4,and HFnu was significantly decreased at T2-4 in group C,and HF was significantly increased at T1-4,HFnu was significantly increased at T2-4 and LF/HF ratio was significantly decreased at T1-4 in group SGB ( P ＜ 0.05 or 0.01 ).LF,LFnu and LF/HF ratio were significantly decreased at T1-4,and HF at T1-4 and HFnu at T2-4 were significantly increased in group SGB as compared with group C ( P ＜ 0.05 or 0.01 ).Conclusion Right SGB can not only inhibit the sympathetic activity induced by carbon dioxide pneumoperitoneum,but also increase the vagal tone.

Nuclear factor-κB(NF-κB),a transcription factor,which widely exists in neuron,neuroglial cell and vascular endothelial cell.It mainly participates in the inflammatory reaction,apoptosis,immunological reaction and other stress reaction of the body.It is considered as an initiation factot of vascular endothelial cell injury.Cytokines.such as tumor necrosis factor-α may promote the inflammatory cascade reaction in cerebral infarction,and may also play an important role in cerebral ischemic injury.
