ABSTRACT
OBJECTIVES@#Acute ischemic stroke (AIS) is one of the main causes of disability in middle-aged and elderly people, and early activity plays an important role in functional recovery. This study aims to understand the factors that affect the implementation of early activity in patients with AIS and to provide reference for promoting early activity implementation and developing intervention strategies for AIS patients.@*METHODS@#Using purposive sampling, 19 AIS patients and their caregivers who visited at Stroke Center in the Third Xiangya Hospital of Central South University and the Third Hospital of Changsha from June to December 2021, as well as 19 medical staff, hospital administrators, or community workers providing medical health services to stroke patients, were selected as interviewes. A semi-structured interview was conducted based on the social ecological theory model, and the Colaizzi seven-step method was used to analyze the interview data.@*RESULTS@#According to qualitative interview results, the factors affecting early activity in AIS patients were summarized into 4 themes and 12 sub-themes: medical staff factors (insufficient knowledge and skills, insufficient knowledge of early activity, unclear division of responsibilities), patient factors (severity of the disease, lack of knowledge, psychological pressure, fear of falling), social environmental factors (lack of social support, shortage of human resources and rehabilitation equipment, insufficient medical insurance support), and evidence and norms (the evidence for early activity needs improvement, lack of standardized early activity procedures).@*CONCLUSIONS@#Early activity in AIS patients is impacted by factors at multiple levels, including medical staff, patients, social environment, and evidence and norms. Developing comprehensive intervention strategies to address these factors can promote early activity implementation in AIS patients.

Purpose@#From the perspective of positive psychology, our study aimed to explore depressive symptomsand psychological well-being among Chinese nurses, as well as analyze the impacts of characterstrengths, self-efficacy and social support on the mental health of nurses. @*Methods@#A cross-sectional and descriptive design using five self-reported questionnaires was used toinvestigate a cohort of 4238 nurses during 2018. A structural equation modeling analysis was used toverify a hypothetical model linking character strengths, self-efficacy, social support, depressive symptoms,and psychological well-being. @*Results@#The prevalence of depression among this cohort of Chinese nurses was 58.1%. The mean scoresfor caring, inquisitiveness, and self-control were 19.93 (SD = 2.82), 15.94 (SD = 3.00), and 16.34(SD = 2.95), respectively. The hypothesized model was a good fit of the data (x2/df = 1.77, p = .183, rootmean square error of approximation = 0.04, goodness of fit index = 1.00, comparative fit index = 1.00,TuckereLewis index = 1.00). Except for the path from self-control to depression, the other hypotheticalpaths investigated were statistically significant. @*Conclusion@#Character strengths were directly and positively associated with psychological well-being.Inquisitiveness was the strongest direct protective factor for depression. In addition, characterstrengths indirectly alleviated depression and increased psychological well-being through mediatingvariables of social support and self-efficacy. This study should alert nurse managers that more attentionshould be paid to the character strengths and mental health of nurses. This study provides evidence forinterventions based on character strengths as a management strategy to support the mental health ofnurses.

ABSTRACT
Objective To evaluate the clinical efficacy of Yangxue-Pinggan decoction on intractable headache. Methods A total of 66 patients with intractable headache who met the inclusion criteria were randomly divided into two groups by random number table method, 33 in each group. The control group was given flunarizine hydrochloride capsule orally, while the treatment group was given professor Guan Youbo's Yangxue-Pinggan decoction. Both groups were treated for 4 weeks. The improvement rates of headache were observed. The headache attacks, the degree of headache, the duration of headache and the accompanying symptoms were scored, and the clinical efficacy was evaluated. Results The total effective rate was 97.0％ (32/33) in the treatment group and 63.6％ (21/33) in the control group, which there was significant difference between the two groups (χ2=11.591, P=0.001). After treatment, the scores of the headache attacks, the degree of headache, the duration of headache and the accompanying symptoms in the treatment group were significantly lower than those in the control group (t=17.689, 12.523, 26.907, 25.569, P<0.001). Conclusions The Yangxue-Pinggan decoction can obviously improve the clinical symptoms of intractable headache, relieve the pain degree and reduce the number of attacks, and its clinical efficacy is better than oral flunarizine hydrochloride capsule.
ABSTRACT
Objective@#To investigate the antimicrobial resistance status and pulsed field gel electrophoresis (PFGE) patterns of Salmonella enteritidis (S.enteritidis) in Shanxi Province in order to provide references for the treatment of Salmonella infection and for tracing the source of outbreaks of foodborne diseases.@*Methods@#Sixty-four S. enteritidis strains were collected by monitoring sites for foodborne diseases from April 2015 to March 2018. Biochemical identification system and serotyping analysis were used for bacterial identification. Drug susceptibility patterns were analyzed with micro-broth dilution method. PFGE was used for molecular typing.@*Results@#The antimicrobial resistance rate of 64 S. enteritidis strains to nalidixic acid (95.31%) was the highest, followed by that to ampicillin (90.63%) and to ampicillin/sulbactam (81.25%). They had lower resistance rates to cefazolin, cefotaxime, tetracycline, ceftazidime, trimethoprim/sulfamethoxzole and ciprofloxacin (3.13%-23.44%) and were all sensitive to chloramphenicol, cefotaxime, azithromycin, imipenem and gentamicin. No statistically significant difference in drug resistance rates was found between the sporadic strains and the outbreak strains (P>0.05). All 64 S. enteritidis strains digested with XbaⅠwere divided into 33 molecular patterns by PFGE. The numbers of bacteria contained in each pattern ranged from 1 to 10 strains. The similarity among patterns was between 54.6% and 100%.@*Conclusion@#More attention should be paid to the drug resistance status of S. enteritidis in Shanxi Province. It is necessary to strengthen the standardized administration of antibiotics. The PFGE patterns of S. enteritidis reveal the presence of significant genetic polymorphism. PFGE is of great significance in analyzing the genetic relationship among S. enteritidis strains and in identifying and tracing the source of outbreaks of foodborne diseases.

ABSTRACT
Objective To provide scientific evidence for nutrition therapy and health education for patients with type 2 diabetes mellitus (T2DM).Methods Based on body mass index (BMI),75 newly admitted T2DM patients were assigned to the normal body-weight group and the over-weight group.Three days before admission,their dietary status was investigated.The average energy intake was compared with the average standard supply.The energy from protein,fat or carbohydrate and the intake of fiber were compared with the recommendations from the American Diabetes Association (ADA).The intake of other nutrient was compared with the recommended nutrient intakes (RNI) or adequate intakes (AI).Results Compared with the standard supply,the average energy intake of the normal body-weight group was significantly decreased (t =2.61,P ＜ 0.05 ),however the average energy intake of the overweight group was significantly increased (t =3.91,P＜0.05).The percentage of energy from protein of the two groups was significantly higher than target levels ( t values were 13.23,21.13 respectively; all P ＜ 0.05 ) ; the percentage of energy from protein of the two groups was significantly higher than target levels (t values were 5.36,10.66 respectively ; all P ＜ 0.05 ) ; however,the percentage of energy from carbohydrate was lower in both groups ( t values were 6.94,15.76 respectively; all P ＜ 0.05 ) ; the average intake of fiber were also lower in both groups (t values were 26.54,40.80 respectively ; all P ＜ 0.05 ).ConclusionThe participants showed insufficient knowledge on healthy diet.Health education could play a role in balanced diet and energy intake.
ABSTRACT
The change of Dietary pattern matched to a change in diseases spectrum of Chinese people in recent years. For improving the function of clinical nutrition branch in hospitals, in accordance with the change in the spectrum and patients' characters, we need to adjust the clinical nutrition treatments individually, to enhance the health education and consultation, to set new dietary pattern for people rationally, and to carry out the scientific research in the field of the relation between concerned chemical elements of organical foods and human health status in general, in order to reach the advanced hospital standards.
ABSTRACT
NB-Cl gene is a potential class IIa bacteriocin gene. To obtain its soluble expression, NB-C1 was fused with the green fluorescent protein (GFP) gene and a recombinant expression vector plVEX 2.4d-GFP-NB-C1 was constructed, which was transformed into Escherichia coli BL21(DE3) pLysS. The expressed fusion protein GFP-NB-CI was purified by Ni-NTA affinity chromatography and the bioactivity was examined using Listeria monocytogenes as the indicator bacteria. The results showed that the expressed fusion protein GFP-NB-C1 was soluble and the final concentration of the purified fusion protein was 36.1 mg/L E. coli culture and had the purity above 95%. The antimicrobial assay of GFP-NB-C1 was analyzed and showed its high activity against Listeria monocytogenes.

Objective: To investigate the effects of lycopene on T lymphocyte subpopulations and pulmonary alveolar macrophagic (PAM) functions in rats with acute lung injury (ALI). Methods: Rats were randomly divided into the following groups. (1) Control group, (2) ALI model group, (3) Low dose group, (4) Mid dose group and (5) High dose group. Control group and ALI model group were treated with solvent of lycopene, and the other groups were gastrically incubated with lycopene. Thirty-five days later, control group were given physiological saline, ALI model group and lycopene administrated groups were injected with lipopolysaccharide (LPS) (6.0 mg/kg) to induce ALI. One hour, four hours or six hours after LPS or physiological saline challenged, abdominal aorta blood for measuring lymphocyte subpopulations and bronchoalveolar lavage fluid for measuring function of PAM were gathered respectively. Results: (1) At h 1, the percentages of CD3+,CD4+ and CD8+ of lycopene administrated groups compared with control group were not significantly different. At h 4, the percentage of CD4+ was similar to that at h 1. As for the percentages of CD3+, except high dose group [(28.8?9.9)%] was significantly lower, low dose, mid dose and ALI model group showed no significant difference compared with control group[(39.5?4.5)%]. The percentages of CD8+ of ALI model and lycopene administrated rats, separately (10.2?3.9)%,(10.3?2.8)%,(9.8?2.8)%,(10.1?3.5)%, had been significantly reduced compared with control group[(15.1?2.5)%]; between ALI model and lycopene ad-ministrated groups there was no significant difference. The instance at h 6 was the same as that at h 4. The percentage ratios of CD4+ T-lymphocyte to CD8+ T-lymphocyte of ALI model rats were not significantly different compared with control group or lycopene administrated groups at h 1 and h 6. At h 4, the ratio of the CD4 + and CD8 + in Low dose and Mid dose groups had significant difference and ALI model, high dose hadn’t when they were compared with control group. (2) Lycopene increased the phagocytic function of PAMs significantly at h 1(P
