Objective To define the conceptual connotation of network dynamic collaboration capacity in medical surge response and construct its theoretical model.Methods A mixed concept analysis method was employed,integrating multidisciplinary literature and collecting empirical evidence through semi-structured expert interviews to extract the concept of network dynamic collaboration capacity in medical surge response.By integrating complex systems,network science,synergetics,and dynamic capability theory,and combining the interview results,the study used the analogy of flood control in hydraulic engineering to develop a"network-dynamic-collaboration"triangular capacity theoretical model.Results It reveals one antecedents(sudden external shocks have led to an abnormal and continuous surge in medical demand),six core attributes(information interconnection accessibility,dynamic resource adaptability,risk perception responsiveness,multi-party collaborative interactivity,service process adaptability elasticity,and learning iterative evolution),and four consequences(mitigation of crowding risk,protection of service continuity,minimization of crisis spillover,and enhancement of system resilience)for the network dynamic collaboration capacity in medical surge response.The theoretical model elucidates the coupling mechanisms among network structural resilience,dynamic regulation processes,and collaborative co-evolution in resisting medical surge.Conclusion The new concept and theoretical model proposed in this study deepen the understanding of medical surge response system mechanisms and offer a theoretical framework and practical guidance for strengthening the full-chain resilience of health emergency systems.

Objective To explore what kind of role serum interleukin 6 (IL-6) and interleukin 18 ( IL-18) play in the relationship between type D personality and acute coronary syndrom (ACS)prognosis.Methods Serum levels of IL-6,IL-18 in all 214 ACS patients were measured with ELISA.According to the scores of type D personality scale(DS14) ,the subjects were divided into the group with type D personality (50 cases)and the one without type D personality ( 164 cases).The serum IL-6 and IL-18 level between the two groups were detected and analyzed.Results There were 23.36% ACS patients with type D personality.The serum IL-6, IL-18levels of the group with type D in ACS acute stage and ACS recovery stage were (2.340 ± 0.081 )OD, (2.016 ±0.023 ) OD and ( 1.460 ± 0.070 ) OD, ( 1.313 ± 0.012 ) OD respectively, significantly higher than those of the group without type D (2.178 ± 0.180)OD, ( 1.849 ± 0.159)OD and ( 1.387 ± 0.091 )OD, ( 1.196 ± 0.132 ) OD respectively(P＜0.01).Conclusion At home and abroad ,there are similar amount of ACS patients with type D personality.The high serum IL-6 and IL-18 levels may play an important role in pathogenesis of relationship between type D personality and ACS poor prognosis.

Objective To investigate effectiveness of meta-cognitive intervention on aged people with middle depression. Methods Geriatrist Depression Scale(GDS) and Hamilton's Depression Scale ( HAMD-17 ) were used to screen out 70 aged people with middle depression from 850 retired soldier cadres dwelling in cpla dalian sanitarium. They were randomly divided into study group( n = 35 ) and control group( n = 35 ). The experimental group received meta-cognitive intervening and general nursing care for 8 weeks, while the control group only received general nursing care for 8 weeks. HAMD-17, GDS, global assessment scale(GAS) and the Metacognitions Questionnaire(MCQ-30) were administered both at the start and the end of the 8th week. Results The total scores in HAMD and GDS were decreased significantly in study group ( HAMD: ( 1 1.54 ± 2.50 ) vs ( 13.06 ±2.82),t= -2.378, P=0. 020;GDS:(12.51 ±2.43) vs (16.06 ±2.48), t= -6. 031, P=0. 000;GAS:(77.71 ±3.03) vs (75.63 ± 3.24), t = 2. 785, P = 0. 007 ). At the end of 8th week, the MCQ total score was significantly decreased in study group (38.69 ± 4. 17,81.37 ± 5.98, t = 34. 652, P ＜ 0. 01 ). Conclusion For aged people with middle depression,good effects are got by the meta-cognitive intervening technique and meta-cognitive intervening technique improve the meta-cognitive level of aged people with middle depressive mood.

Objective To investigate freshmen's prevalence of depression disorder and to analyse the in-fluential factors on depression in military colleges. Methods Depression, self-consciousness, coping style, per-sonality feature, birth background and other factors were investigated by MMPI and related questionnaires in 683 freshmen of military colleges. Results The prevalence of depression disorder was 3.66% ; $i, Dy, Ne mean scores of freshmen with depression disorder were significantly higher than without depression disorder(t= 5. 348,3. 879,2. 997 ) (P<0.05, P<0.01)), otherwise, Do, Pc , PEI ones were significantly lower than without depres-sion disorder( t= -2.171, -2.602, -2.62) (P<0.05, P<0.01);D mean score of all subjects was significant-ly related to Si, Dy, Do, Nc, PEI,Pe(r=0.600,0.465, -0.356,0. 240, -0. 353, -0. 146) (P<0.05, P<0.01 ). And also Si,Do,Pc,Nc got into regression quotation. Condusion Freshmen's depression is associated with their personalities,coping style and self-consciousness, however,their personalities, coping style were most important pre-dictors.

Objective To explore how the freshmen's self-efficiency influence the acute stress psychological reaction. Methods Self-efficiency, coping styles, personality were assessed by relevant questionnaires, and acute stress psychological reaction was measured by means of designing a experiment in 683 freshmen of military colleges.Results ①Freshmen with low self-efficiency had higher scores in Si,Mas,Dy,Nc(t=8.05,7.49,6.36,3.93,P<0.01)and lower scores in Do,Re,Pc(t=5.12,2.11,3.90,P<0.05 or P<0.01)than freshmen with high one.Among all factors mentioned above, Si,Dy,Pc got into regression equation. ② Freshmen with low self-efficiency had lower stress score than ones with higher self-efficiency(t=3.92,P<0.01).Freshmen's self-efficiency was positively correlated to total scale score and 3 subscale scores of the acute psychological stress reaction questionnaire(r=0.187～0.346,P<0.05,P<0.01).Conclusion Personality,coping style exerted influence on the freshmen's self-efficiency which is a mediator between stressors and acute psychological stress reaction.
