Objective@#To investigate the recessive infection rate of healthy children and guardians in different epidemic periods of hand, foot and mouth disease (HFMD) in Qingdao, analyze the risk factors affecting recessive infection, so as to provide the basis for HFMD prevention and control.@*Methods@#In the nonepidemic period of 2022, the random cluster sampling method was used to selected 546 children and guardians from 4 childcare institutions in Laoshan District and Pingdu City. In the epidemic period of 2023, 690 children and guardians were selected from 6 childcare institutions in Shibei District, Laoshan District and Pingdu District. A questionnair survey was conducted in the epidemic period. Logistic regression analysis was used to analyze the factors affecting the recessive infection. Dominance analysis was used to explore the relative importance of the risk factors affecting recessive infection.@*Results@#The results showed that the recessive infection rates of healthy children and guardians in the epidemic period were 18.84% and 13.62%, respectively; the recessive infection rates were 9.09% and 4.44% in the nonepidemic period, respectively. The results of multivariate Logistic analysis showed that rural areas (OR=4.71, 95%CI=2.57-8.61) and recessive infection of guardians (OR=18.62, 95%CI=7.45-46.56) were positively correlated with recessive infection of HFMD in healthy children (P<0.05). Washing hands (OR=0.09, 95%CI=0.04-0.20), using towels alone (OR=0.17, 95%CI=0.07-0.40), and EV71 vaccination (OR=0.42, 95%CI=0.20-0.87) were negatively correlated with recessive infection of HFMD in healthy children (P<0.05). Public toilets (OR=3.02, 95%CI=1.50-6.09) and drying bedding once per quarter (OR=3.89, 95%CI=1.75-8.68) were positively correlated with recessive infection of HFMD in healthy guardians. Housing with good lighting (OR=0.31, 95%CI=0.12-0.79), and tableware disinfection (OR=0.31, 95%CI=0.15-0.65) were negatively correlated with recessive infection of HFMD in healthy guardians (P<0.05). The results showed that recessive infection of guardians was relatively the most important for healthy children (41.51%), and tableware disinfection was relatively the most important for recessive infection of guardians (28.87%).@*Conclusions@#The recessive infections of HFMD are common among healthy populations in Qingdao, and the recessive infection rate among children during the epidemic period is relatively higher. Guardians play an important role in the recessive infection of healthy children. Therefore, healthy education should be strengthened for key populations, especially to enhance parents awareness of prevention and control to reduce the occurrence of recessive infections of hand, foot and mouth disease in children and guardians.

Objective:To explore the effect of comfort nursing intervention in hospice care for advanced cancer patients at home, and to provide reference for hospice care for advanced cancer patients at home.Methods:A randomized controlled trial was conducted. A total of 105 patients with advanced cancer who were treated in the Cancer Hospital Affiliated to Harbin Medical University from January to February 2023 were selected as the research objects. According to the random number table, they were divided into control group of 53 cases and intervention group of 52 cases. The control group received routine nursing methods, while the intervention group received comfort nursing interventions on this basis. The intervention lasted for 4 weeks. The changes in palliative care outcomes, quality of life and death anxiety were compared between the two groups before and after intervention.Results:Totally 105 cases were included, 53 cases in the control group and 52 cases in the intervention group. In the control group, there were 25 males, 28 females, aged (58.96 ± 10.71) years old; in the intervention group, there were 22 males, 30 females, aged (59.82 ± 10.53) years old. Before intervention, there was no statistically significant difference in palliative care outcomes, quality of life and cancer death anxiety scores between the two groups of patients (all P>0.05). After intervention, the total score of palliative care outcomes in the intervention group was (13.34 ± 5.88) points, significantly lower than (16.15 ± 5.72) points in the control group, with a statistically significant difference ( t = 2.48, P<0.05). The overall health status score of quality of life was (68.55 ± 9.34) points in the intervention group, higher than (63.01 ± 9.28) points in the control group ( t = 3.05, P<0.05). The total score of cancer death anxiety was (8.85 ± 2.72) points, significantly lower than (10.59 ± 3.14) points of the control group, with a statistically significant difference ( t = 3.04, P<0.05). Conclusions:The application of comfort nursing mode in home based hospice care can improve the quality of hospice care for advanced cancer patients, reduce their level of death anxiety, and is of great significance for improving the quality of life of advanced cancer patients.

Objective To research sorption of local anesthetic by fat emulsion with different content of lipid in vitro and then to discuss the mechanism of action of fat emulsion for treatment of local anesthetic toxicity. Methods 10%,20%,30% fat emulsion was added to the bupivacaine hydrochloride and ropivacaine hydrochloride.After the mixture was vortexed for 10 mins,it was vibrated in thermostatic water bath at 37 ℃ for 15 h,then centrifugated and got the aqueous phase to HPLC test.The chromatography was carried on a C18column(4.6 mm×250 mm,5 μm ),the mobile phase was composed of acetonitrile-natrium biphosphoricum(25:75),the flow rate was 1 mL·min-1,the column temperature was 30 ℃ and the detection wavelength was set at 210 nm. Results Under the condition of this test,the linear ranges and linear equations for bupivacaine hydrochloride and ropivacaine hydrochloride were 0.3-3.0 μg·mL-1,Y=0.093 6X-0.017 3(r=0.999 6),and 0.3-3.0 μg·mL-1,Y=0.086 6X-0.022 3(r=0.999 1) respectively.The lowest limit of quantitation were both 0.05 μg·mL-1(S/N>3),and the ingredients showed good relationships between the peak area and the concentration.Sample reproducibility was good because the test sample was stable in 5 h.The extraction rates of bupivacaine hydrochloride by 10%,20%,30% fat emulsion were 46.0%,70. 4%,89.2% respectively.The extraction rates of ropivacaine hydrochloride by 10%,20%,30% fat emulsion were 51.3%,71.6%, 90.7% respectively. Conclusion Electric potential and the pH value of the 10%,20%,30% fat emulsion are similar,while the particle size increase slightly.Free bupivacaine hydrochloride and ropivacaine hydrochloride can be absorbed and with the increase of fat content,the extraction of local anesthetic is increased.The mechanism of action of fat for the treatment of local anesthetic toxicity maybe related to that fat emulsions can provided lipid,so that the excessive local anesthetic or those which had already distributesd in tissue can re-dispersed in lipid,and then the plasma concentration of local anesthetic is reduced,the toxicity is also reduced.

@#ObjectiveTo determine the static equilibrium of elderly individuals over the age of 60 and the correlation to the age. Methods142 elderly subjects (60～95 years old) were divided into 7 groups: 60～65 years old group, 66～70 years old group, 71～75 years old group, 76～80 years old group, 81～85 years old group, 86～90 years group, and >90 years old group, 24 cases 18～30 years old as the control. The static equilibrium was examined by measuring the stability index （ST） and the spectrum analysis of postural sway under following 4 conditions: standing on solid surface with eyes open （NO），standing on solid surface with eyes closed （NC）， standing on pillows with eyes open （PO）， and standing on pillows with eyes closed （PC） using Tetrax Balance System. ResultsThe ST and the intensity of postural sway increased in the elderly group compared with the control group. NO: there were significant differences (P<0.01) in ST, F1, F4, F6, F8 among the 81～85 years group, 86～90 years old group, >90 years old group and the control group. NC: there were significant differences (P<0.01) in ST, F1, F4 among all the elderly groups and the control group, and in F6, F8 among the >66 years groups and the control group（P<0.05）. PO: there were significant differences (P<0.01) in ST, F4, F6 among the >66 years old groups and the control group, and in F1, F8 among the >71 years old groups and the control group（P<0.05）. PC: there were significant differences (P<0.01) in ST, F4 among all the elderly groups and the control group, in F6 among the >66 years groups and the control group, in F8 among the >76 years old groups and the control group, and in F1 among the >80 years old groups and the control group（P<0.05）. The ST distributed as NOP<0.01）. There were similar changes in the intensity of postural sway of F1, F4, F6, F8 bands. ConclusionThere is the significant decline of the static equilibrium in the subjects aged 80 or over and no significant decline of the static equilibrium in the subjects aged 60～80 whose compensation in the static balance may decrease.

@#ObjectiveTo assess the effect of the vestibular, visual, and somato-sensation on the fall risk in elderly individuals. Methods56 subjects aged 60 or over were measured with the static postural stability and fall risk, including stability index （ST）, the body weight distribution index (WDI) and the fall index (FI) under 4 conditions: standing on solid surface with eyes open （NO），standing on solid surface with eyes closed （NC）， standing on pillows with eyes open （PO），and standing on pillows with eyes closed （PC）. ResultsThe mean of fall index of all subjects was (48.21±26.47). The ST was different among groups, which was PC>PO>NC>NO （P=0.000），but no significant differences were noted between PO and NC groups （P=0.705）. The WDI was not significantly different among the 4 groups (P>0.05）. The FI was correlated with ST （P<0.05）, but not correlated with the WDI（P>0.05）. ConclusionAll of the vestibular, visual, and somato-sensory systems play an important role in the balance, postural stability and falls. The ST is sensitive to evaluate the static balance function and associated with the fall risk in an elderly population. The WDI is not sensitive enough to evaluate the static balance function and fall risk.
