Objective To analyze the current situation of healthcare-associated infection (HCAI) management of fever clinics among different levels of medical institutions in Wuhan, and to provide a scientific basis for improving hospital infection management. Methods In January 2023, a network questionnaire survey was conducted on medical institutions with fever clinics in Wuhan. Results A total of 72 medical institutions were investigated, of which 58.33% had CT, and 48.61% had fever clinics for children. The total qualified rate of HCAI management was 78.28%. The qualified rates of four primary indicators, including hospital management, diagnosis and treatment environment protection, training and education, and implementation of infection control measures, were 82.27%, 71.49%, 75.93%, and 81.31%, respectively. There were statistical differences among different levels of medical institutions (all P<0.01). Among the 13 secondary indicators, the qualified rates of 7 indicators were more than 80%, with the highest being medical item management (93.06%), medical waste disposal (89.72%), and personnel management (83.33%), and the lowest being facilities and equipment (66.32%), and patients and accompanying personnel education (66.67%). Among the 65 tertiary indicators, 30 had a pass rate great than 80%. Conclusion Wuhan actively promotes the construction of fever clinics in medical institutions, and the overall situation of HCAI management is good. However, there are still some problems to varying degrees, especially in the layout procedures, hand hygiene, and staff training of fever clinics in secondary and lower medical institutions, which should be further strengthened.

Objective To investigate the effects of harmine(HM)on the expression level of mitochondrion fusion related proteins and mitochondrial function injury in PC 12 cells.Methods PC 12 cells were divided into cell control group,HM group,mitochondrion mitosis inhibitor Mdivi-1 group,HM+Mdivi-1 group,mitochondrion fission agonist WY14643 group,HM+WY14643 group,with drug concentrations of 1,10,25,50,100 μmol·L-1.After 24 h treatment,the MTT method was used to detect the cell survival rate,and a microscope was used to observe the cell morphology,MitoTracker Red probe staining was used to observe the mitochondrial morphology and the length ratio of vertical and horizontal axes,JC-1 staining was used to detect the mitochondrial membrane potential,and a kit was used to detect ATP level and lactate dehydrogenase(LDH)activity.Immunofluorescence staining and Western blotting were used to assess the expression levels of caspase-3,apoptosis-promoting protein(Bax)cytochrome C(cyt-c),mitochondrial fusion protein(Mfn2)and mitochondrial mitotic protein(Drp-1).The interference sequence of Drp1 was transfected by electroporation,and the siRNA sequence with good transfection effect was screened.The related indicators were detected by fluorescence method,MTT method,and immunoblotting method in cooperation with drug intervention.Results MTT results showed that compared with the cell control group,the survival rate of HM group,Mdivi-1 group,HM+Mdivi-1 group,WY14643 group and HM+WY14643 group decreased significantly(P＜0.01),and the EC50 were(11.48±2.32),(12.35±1.67),(14.88±2.07),(39.14±3.25),(20.09±1.97),respectively.According to this,subsequent experiments selected 20 μmol·L-1for HM,WY 14643 and HM+WY14643 as working concentrations to construct PC 12 cell model.Microscopic observation and MitoTracker Red probe staining showed that the cell density in the drug group decreased in varying degrees,and a transition from branched to round morphology in the drug-treated groups was observed.The morphology of mitochondria tended to be round,and the ratio of the length of the longitudinal axis to transverse axis was(3.33±0.72)in the cell control group,(2.19±0.58)in the HM group,(2.45±0.44)in Mdivi-1 group,and(1.43±0.62)in HM+Mdivi-1 group,respectively.The results of JC-1 staining showed that compared with the cell control group,the mitochondrial mode potential of the HM group significantly decreased(P＜0.01).ROS significantly increased(P＜0.01)and ATP levels decreased(P＜0.01),and LDH enzyme activity increased(P＜0.01).Immunofluorescence staining and Western blotting results showed that compared with the cell control group,the expression levels of proapoptotic proteins Bax,cytochrome C,and caspase-3 in the HM group were significantly increased(all P＜0.01).Compared with the cell control group,the expression level of mitochondrial fission related protein Drp1 in HM group was significantly higher(P＜0.01).The expression level of mitochondrial fusion related protein Mfn2 significantly decreased(P＜0.01).After specific interference with Drp1 and synergistic intervention with HM,the survival rate of PC 12 cells in each interference group decreased compared to each drug intervention group.The expression of Drp1 and Mfn2 was downregulated,and the differences were statistically significant(P＜0.05 or P＜0.01).Conclusion HM can reduce the mitochoudrial membrane potential and ATP levels by accumulating ROS,there by activating the caspase-3 apoptosis pathway and promoting cell apoptosis.Mitochondrial fusion division may be involved in the damage of PC12 cells caused by HM,initiating apoptosis through the mitochondrial pathway.

Objective:To explore the current status and influencing factors of fertility intention to have a third child among childbearing age women in Heilongjiang Province under three-child policy.Methods:From January to April 2023, convenience sampling was used to select 10 600 women of childbearing age from ten districts and counties in five cities in Heilongjiang Province (Jiamusi, Qiqihar, Harbin, Heihe, Suihua) as research subjects. The Fertility Intention to Have a Third Child Questionnaire among Childbearing Age Women in Heilongjiang Province was used to investigate women of childbearing age. Multi-class Logistic regression was used to explore the influencing factors of fertility intention of childbearing age women to have a third child.Results:A total of 10 600 questionnaires were distributed, and 9 554 valid questionnaires were collected, with a valid response rate of 90.13% (9 554/10 600). Among 9 554 women of childbearing age, 2 248 had the intention to have a third child, 5 036 had no intention, and 2 270 were uncertain. Multi-class Logistic regression analysis showed that age, education level, per capita monthly income of the family, occupation, fertility status, pregnancy complications, economic pressure to have a third child, parents' attitudes towards having a third child, and satisfaction with childcare services were the influencing factors of the fertility intention of childbearing age women in Heilongjiang Province to have a third child ( P<0.05) . Conclusions:Under the three-child policy, women of childbearing age in Heilongjiang Province have a low intention to have a third child. Relevant departments should formulate policies based on the influencing factors.

Objective:To investigate the protective effect of ulinastatin on sepsis-acute kidney injury (SA-AKI) by NF-κB signaling pathway.Methods:Total of 60 mice were randomly(random number) divided into sham group, cecal ligation puncture group (CLP group) and ulinastatin treatment group (CLP+UTI group). Ulinastatin treatment group was intraperitoneally injected with ulinastatin 50 000 U/kg once a day. 24 hours after operation, five mice were sacrificed, the kidney tissues were collected to observe renal histopathology by HE staining. The macrophage infiltration was observed by immunohistochemistry. The remaining mice in each group were used to calculate the survival rate of 7-day after operation. HK-2 cells were stimulated by LPS to obtain the SA-AKI model, and the cells were divided into control group, LPS group and LPS + UTI group. CCK-8 assay was used to detect cell viability, EdU assay was used to detect cell proliferation, and JC-1 assay was used to detect mitochondrial damage. The phosphorylation degree of NF-κB was detected by western blot. Inflammatory factors concentrations of cellular supernatant were detected by ELISA assay.Results:Compared with the sham group, the kidney tissue of mice in CLP group showed that kidney pathological obvious changed, the infiltration of macrophages increased, and the survival rate of mice decreased. CLP+ UTI group reduced the pathological changes and the infiltration of macrophages, improved the survival rate of mice. Compared with control group, LPS group obviously inhibited the cells activity and proliferation of HK-2 cells, damaged the mitochondrial membrane potential of HK-2 cells. Compared with LPS group, LPS+ UTI group attenuated the phosphorylation of NF-κB, decreased the secretion of inflammatory factors, rescued the activity and proliferation of HK-2 cells, and reduced the damage of HK-2 mitochondrial membrane potential.Conclusions:Ulinastatin can reduce mitochondrial damage, inhibit the secretion of inflammatory factors and improve the function of renal tubular epithelial cells through regulating NF-κB signaling pathway.

ObjectiveChronic heart failure （CHF） is the terminal stage of cardiovascular disease. The adverse cardiovascular events of CHF patients with weakness have increased significantly. Traditional Chinese medicine （TCM） has a good effect on CHF. However，there are few reports on the clinical observation of the treatment of CHF with weakness in elderly patients by TCM combined with conventional health-preserving exercises. This study aimed to explore the clinical efficacy of Qiangxin decoction combined with Baduanjin in the treatment of elderly patients with CHF and weakness. MethodSixty CHF patients with Qi deficiency，blood stasis，and water retention syndrome admitted to the Cardiovascular Department of the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2020 to December 2021 were enrolled. The patients in the control group were treated with conventional western medicine according to the guidelines，while those in the treatment group received additional Qiangxin decoction and Baduanjin exercise based on the therapeutic protocol of the control group. The levels of serum N-terminal B-type brain natriuretic peptide precursor （NT-proBNP），creatine kinase （CK），lactate dehydrogenase （LDH），free fatty acid （FFA），left ventricular ejection fraction （LVEF），left ventricular end-diastolic dimension （LEVDD），6-minute walk distance （6MWD），Minnesota Living with Heart Failure Questionnaire （MLHFQ）， and Tilburg Frailty Indicator （TFI） scores of the two groups were observed before and one month after treatment. At the same time，the re-admission within three months was compared between the two groups. ResultThere was no significant difference between the two groups in terms of the general data and the therapeutic indexes before treatment. After treatment，the NT-proBNP，CK，LDH，FFA，LVEDD，MLHFQ， and TFI scores of the two groups were lower than those before treatment（P<0.05，P<0.01）， and the LVEF and 6MWD were higher（P<0.05，P<0.01）. The efficacy of the treatment group was superior to that of the control group after treatment （P<0.05，P<0.01）. The re-admission rate within three months in the treatment group was 7.1% （2/28）， lower than 30.8% （8/26） in the control group （χ²=4.897，P<0.05）. ConclusionQiangxin decoction combined with Baduanjin is helpful to improve the body energy metabolism，heart function，quality of life，and weakness level of elderly CHF patients with weakness， and reduce the rate of re-admission.

Objective: To establish the norm of the Physical Activity afterschool Questionnaire for Preschooler(P-PAQ) in urban areas of China, so as to provide a basis for graded guidance from the family perspective and to improve children s physical activity levels. Methods: From October 2020 to January 2021, 6 267 children aged 3-6 years old were recruited from 40 kindergartens in eight cities across six major administrative regions by stratified cluster sampling, and the P-PAQ initially developed by the researchers of this study were completed by the primary caregivers. The questionnaire was administered to collect data relating to the amount of physical activity undertaken by the preschoolers, and the norm was determined by quartiles. Data relating to parental concepts of sports and parental behavior were assessed by calculating mean scores in order to establish the norm. Results: Among preschoolers in urban areas, the M(P 25 ，P 75 ) of total physical activity time (min/day), moderate-to-vigorous physical activity time (min/day), outdoor time (min/day) and screen time (min/day) on school days outside kindergarten and on weekends were 84 (54,120), 22 (8,40), 12 (0,24) and 18 (6,30), and 170 (115,240), 60 (30,95), 90 (35,120) and 30 (20,60), respectively. When the score of parents sports concept and behavior (total score of 40) were≥34, 29-<34, 24-<29, <24, it was defined as four levels about above medium, medium, lower medium and lower, respectively. And for two dimensions，when the score of parental sports concept were ≥19, 17-<19, 15-<17, <15，and the score of parental behaviors were ≥16, 12-<16, 8-<12, <8, it was defined as four levels about upper medium, medium, lower medium and lower, respectively. Conclusion The norm of extracurricular activities among preschool children in Chinese cities has good representativeness and appropriate threshold values, which could provide a valuable reference for early assessment, as well as guidance in relation to out-of-school physical activity behaviors among children aged 3-6 years old.

BACKGROUND: Low-back pain (LBP) in nurses is a major health concern that affects their quality of life and ability to work, with consequences for their economic status. OBJECTIVE: This study evaluates the effect of low-level laser acupuncture combined with auricular acupressure (LAA) on pain intensity, pain interference and quality of life in nurses with LBP. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This randomized controlled trial recruited a convenience sample of hospital-based nurses from one teaching hospital in Taiwan, China. Participants were randomly assigned to the LAA group (n = 38) receiving low-level laser acupuncture and auricular acupressure for 4 weeks, and the control group (n = 38) receiving only sham laser acupuncture treatment without laser energy output. MAIN OUTCOME MEASURES: Data were collected for the primary pain outcome using the Short Form of the Brief Pain Inventory, while the secondary outcome, quality of life, was evaluated using the Roland-Morris Disability Questionnaire. Both primary and secondary outcomes were scored before the intervention, and after 2-week and 4-week intervention. The rate of LBP recurrence was evaluated at the 4th week and 8th week after the end of intervention. RESULTS: After controlling for prior pain, the result of linear mixed model analysis showed trends in significant between-group differences in the level of current pain occurring in week 4 (P < 0.001), worst pain in week 2 (P < 0.001) and week 4 (P < 0.001), least pain in week 2 (P = 0.032) and week 4 (P < 0.001), pain interference in week 2 (P = 0.009) and week 4 (P < 0.001), and in the life dysfunction in week 2 (P < 0.001) and week 4 (P < 0.001). Recurrence rates of LBP at the 4th and 8th weeks after the end of intervention were 0% and 36.89% in the LAA group, and 69.44% and 36.11% in the control group. CONCLUSION: This study shows that 4-week LAA intervention reduced pain intensity and pain interference, and improved quality of life for hospital-based nurses with LBP. These effects were maintained continuously for at least 4 weeks after the intervention. The nonpharmacological intervention, LAA, may be another efficacious, feasible, noninvasive, analgesic intervention for LBP.
