Objective:To study development problems and countermeasures of the health emergency management system in a city based on the grounded theory, for references on the construction of a new round of urban health emergency management system.Methods:From June 2020 to April 2021, 61 health emergency management personnel were selected using the objective sampling method from the municipal health commission and disease prevention and control center of a city, and from 11 district health bureaus and disease prevention and control centers, for semi-structured interviews. Grounded theory method was used to analyze the interview data.Results:288 concepts, 79 initial categories, 15 sub-categories, and 5 main categories were extracted from the interview materials. The urban health emergency management system was affected by a variety of constraints such as the weak construction of public health talent team, non-standard plan management, and limited information sharing. There was a fragmentation dilemma in structure and mechanism. It was necessary to strengthen policy support and emergency resource allocation to promote the reconstruction of the health emergency response system. Among them, policy support and emergency resource allocation were prerequisites, and the remodeling of health emergency system was the core process.Conclusions:There were problems such as insufficient resource supply and weak plan management in the construction of the city′s health emergency management system. We should establish a high-level driven policy system, strengthen the resource allocation of peacetime and wartime, and reshape the system and mechanism of coordination and integration, so as to continue to promote the continuous development of the health emergency management system.

Objective:To investigate the impacts of stroke volume variation (SVV)-guided goal-directed fluid therapy on intraoperative signs, intestinal barrier function and prognosis in patients undergoing laparoscopic radical rectal cancer surgery.Methods:A total of 90 patients who underwent laparoscopic radical resection for rectal cancer in Peking University International Hospital from May 2020 to May 2022 were prospectively selected as subjects, and divided into SVV group (45 cases) and traditional infusion group (45 cases) by random number table method. The SVV group was given SVV-guided goal-directed fluid therapy, and the traditional infusion group was given central venous pressure (CVP)-guided goal-directed fluid therapy. The operation-related indicators (urine volume, crystalloid volume, colloid volume, total fluid volume, blood loss and operation time), intraoperative signs indicators[heart rate (HR), CVP, mean arterial pressure (MAP)], intestinal barrier function indicators [diamine oxidase (DAO), D-lactic acid], inflammatory factor levels [interleukin-10 (IL-10), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)], and the incidence of complications were compared between the two groups.Results:There was no significant difference in the urine volume, blood loss and operation time between the two groups (all P>0.05), while the crystalloid volume, colloid volume and total fluid volume in the SVV group were greatly lower than those in the traditional infusion group (all P<0.05). There was no significant difference in HR between the two groups at different time points ( P>0.05). Compared with T 0, CVP at T 1 in the two groups was significantly decreased (all P<0.05), and increased at T 2 and T 3 compared with T 1 (all P<0.05). There was no significant difference in MAP at different time points in the SVV group (all P>0.05). The MAP at T 1, T 2 and T 3 in the traditional infusion group was significantly lower than that at T 0 (all P<0.05), and the MAP at T 1, T 2 and T 3 in the SVV group was significantly higher than that in the traditional infusion group (all P<0.05). Compared with T 0, DAO and D-lactic acid levels were significantly increased at T 1, T 3, T 4 and T 5 in the two groups (all P<0.05), and DAO and D-lactic acid levels at T 1, T 3, T 4 and T 5 in the SVV group were significantly lower than those in the traditional infusion group (all P<0.05). Compared with T 0, serum IL-10 level in the two groups was significantly decreased at T 4 ( P<0.05), and serum IL-6 and TNF-α levels were significantly increased at T 4 (all P<0.05). The serum levels of IL-10, IL-6 and TNF-α in the SVV group at T 4 were significantly different from those in the traditional infusion group (all P<0.05). Compared with T 4, the serum levels of IL-10 at T 5 were significantly increased (all P<0.05), while the levels of IL-6 and TNF-α were significantly decreased (all P<0.05), but there was no statistical significance between the two groups (all P>0.05). The incidence of postoperative infection, anastomotic fistula, vomiting and nausea in SVV group (13.33%) was significantly lower than that in traditional infusion group (35.33%) ( P<0.05). Conclusions:SVV-guided goal-directed fluid therapy for patients undergoing laparoscopic radical rectal cancer can effectively stabilize intraoperative vital signs, reduce inflammation, improve intestinal barrier function, and improve prognosis.

Objective To understand the current situation and existing problems in the training of healthcare-asso-ciated infection(HAI)management,and provide scientific basis for strengthening the management of HAI preven-tion and control system.Methods A questionnaire survey was adopted to investigate situation of training on HAI in 15 provincial-level HAI training agencies in China during the past 30 years,and basic condition of training on HAI management in recent 5 years.Results Among 15 provincial-level training agencies,66.67%(n=10)were respon-sible by HAI management quality control centers,80.00% have already conducted training in each city,53.33%carried out training for 10 to 20 times,33.34% performed training for ≤2 times per year.Of 33 728 trainees in 2011-2015,41.30% were 41-50 years old,61.82% were nursing staff,50.56% had bachelor degree,43.96%were with the intermediate professional title.Most trainers were HAI prevention and control experts in their respec-tive province,accounting for 68.07%,the curriculums were mainly designed on professional course,and only 26.78% were involved in management.Conclusion Professional structure of HAI management personnel is not reasonable,faculty is imbalance,knowledge update is lacking,and HAI training and education system need to be improved further.

Objective To investigate the mechanism of TNF-related apoptosis-inducing ligand (TRAIL) promoting apoptosis of pancreatic cancer cells SW1990, Patu8988 and BxPC3. Methods Three kinds of pancreatic cancer cells SW1990, Patu8988 and BxPC3 were transfected with the pCA13 plasmid carrying TRAIL gene ( pCA13 TRAIL group) and the blank plasmid control ( pCA13 group) , respectively. The expression of TRAIL mRNA in transfected cells was detected by RT-PCR, and the expression of TRAIL protein was detected by Western blot. The apoptosis rate and expression of TRAIL receptor R1 and R2 were detected by flow cytometry. Apoptosis was detected by TUNEL and Hoechst double staining, and observed by electron microscopy. The expression of caspase-3 in transfected cells was detected by immunohistochemistry. Results SW1990, Patu8988 and BxPC3 cells can expresse TRAIL mRNA and protein within 24 h after transfection. The apoptotic rate at 24 h after transfection was (27. 30 ± 5. 14)％, (13. 52 ± 0. 95)％ and (31. 40 ± 8. 70)％,respectively, which was higher than that of pCA13 group [(10. 58 ± 1. 88)％,(8. 42 ± 0. 46)％ and (16.11 ±1.66)％], respectively. The expression rates of TRAIL-R1 were (61.37 ± 3.05)％,(42.10 ± 5. 11)％ and (36. 64 ± 4. 84)％, respectively, and the expression rates of TRAIL-R2 were (36. 20 ± 4. 83)％,(37. 26 ± 8. 46)％ and (24. 32 ± 3. 71)％, respectively,which were higher than those of pCA13 group except PATU8988 cells. Positivity rates of caspase-3 were ( 14. 64 ± 5. 35 )％, ( 9. 92 ± 5. 50 )％ and (16. 12 ± 6. 74)％, which were obviously higher than ( 3. 01 ± 1. 50 )％, ( 1. 75 ± 0. 50 )％ and ( 3. 79 ± 1. 58)％ in pCA13 group,and the differences were statistically significant(P<0. 05). Conclusions TRAIL could up-regulate the expression of TRAIL R1 and R2 in multiple pancreatic cancer cell lines in vitro, and thus promote cell apoptosis.
