A total of 444 health piglets were randomly divided into 6 groups, including five medication groups （72 piglets in group A, 74 pig- lets in group B, 72 piglets in group C, 76 piglets in group D, 76 piglets in group E） and one control group （74 piglets）. The piglets in experimental groups were treated drugs once a day for successive 5 days at 30, 60, 90, 120 and 150 of age. The piglets in control group were free of medication. At 70 and 140 days of age, 15 piglets of each group were randomly selected to collect their blood sermn. The Mycoplasma hyopneumoniae （M-Hyo） antibodies in serum were measured by en- zyme-linked immunosorbent assay （ELISA）. During the experiment, the incidence rates of respiratory disease, lung lesion, feed conversion rate, average daily gain （ADG）, and mortality rate of pigs were also observed and recorded. The results showed that the five drugs had significant difference in preventative effects. Group C （Zhiyuanjing group） received the best preventive effect and the highest economic benefits. Compared with control group, the ADG and feed conversion rate in group C were increased by 7.53% and 9.09%, respectively; the incidence rate of respiratory disease was reduced by 13.44% and lung lesion was alleviated by 81.43% ; and the earnings of each pig could rise by 132.70 yuan. The preventative effect and economic benefit of the drugs was sequenced by Chansu Kechuanling and Bingchan Kechuanwang. Wante Feilin and amoxicillin had weaker preventive effects against MPS but greatly influenced growth performance of pigs, so they should be used alternatively with other drugs.展开更多

Methods: a total of 310 children with eruption of mandibular first molars who underwent routine physical examination in kindergartens in this city from August 2018 to October 2019 were randomly selected as research objects. They were randomly divided into the control group and the study group with 155 children in each group receiving different oral care measures, and the situation in the next 24 months was tracked and studied. The children in the control group were given routine oral care such as brushing their teeth in the morning and evening and gargling after meals, while the children in the study group were given oral care based on this. The occurrence of caries of the first permanent molars in the two groups at 6, 12, 18 and 24 months after physical examination and the preventive effect of the two kinds of care measures were observed and compared. Results: after 6 months of nursing, there was no significant difference in the incidence of caries between the two groups (1.83%vs2.17%) (P > 0.05). In the last three stages, the incidence of dental caries in children showed an upward trend. The incidence rates in the study group were 6.33%, 9.67% and 13.17% respectively, and the incidence rates in the control group were 14.33%, 19.50% and 24.83%, respectively. Compared with the control group, the incidence rates of dental caries in the study group were lower than those in the control group at each stage (p < 0.05). In addition, 6 months after nursing, there was no significant difference between the two groups (P > 0.05). In the last three stages, the average caries and caries surface of the two groups increased gradually, but the average caries and caries surface of the study group were lower at each stage (P < 0.05). Conclusion: fluorine protective paint has good preventive effect on children's first permanent molar caries, and the incidence of dental caries is low within two years, which is worthy of wide promotion.展开更多

Materials and Methods: This is a systematic review including articles relating to the evaluation of road safety interventions implemented in Africa that were searched on electronic databases: PubMed, Scopus, Lissa, Google Scholar, and African Journals Online. Selection of articles and data extraction was conducted by two pairs of reviewers. Data quality was checked according to the type of study. A qualitative analysis of the data was carried out and a narrative approach was adopted to describe and synthesize the results. Results: A total of twenty-nine articles were selected including one cross-sectional study, seven time series, twenty-one quasi-experimental studies of which six randomised and fifteen non-randomised studies. The type of interventions evaluated was aimed at all types of users and was based on different interventions such as institutional strengthening, law enforcement, awareness raising, training or user education, vehicle maintenance and infrastructure improvements. For fourteen studies all the expected indicators had changed favourably and for twelve the indicators had partially changed. The studies that showed significant change were institutional strengthening, law enforcement, awareness raising, training, or user education interventions, development of Uber transport services, distribution of equipment, and a combination of interventions. Conclusion: This situation is indicative of insufficient policy investment in research but also in the field of road safety in general.展开更多

Method: They are a randomized controlled trial (RCT) on FIFA 11+ integrated warm-up, FIFA 11+ Kids integrated warm-up, and neuromuscular training (NMT) warm-up for the prevention of knee joint in juvenile soccer players by a computer search of CNKI, CBMdisc, WanFangdata, Pubmed, Web of science, and SPORTDicus database. The search period was from the establishment of each database to February 2022. Two investigators screened the literature, extracted data, and assessed risk bias for the included studies according to the pre-defined inclusion and exclusion criteria, and finally analyzed the data using Stata 14.0 software and OpenBUGS software. Results: A total of 10 RCT studies with 17,143 subjects, spanning the age range of 7 to 19 years, were included. The results of the reticulated Meta-analysis showed that all three warm-up modalities were effective in reducing the incidence of knee injuries in junior soccer players compared to conventional warm-up, with the optimality in descending order of FIFA 11+ Kids comprehensive warm-up (SUCRA = 85.3), neuromuscular training warm-up (SUCRA = 66.7), and FIFA 11+ combined warm-up (SUCRA = 44). Conclusion: The FIFA 11+ Kids comprehensive warm-up is the most effective warm-up exercise for the prevention of knee injuries in junior and child soccer players, but the above findings need further validation due to the quantity and quality of the literature and the quality of the evidence.展开更多

文摘In the Upper Silesian Coal Basin(USCB),coal seams are exploited under progressively more difficult geological and mining conditions(greater depth,higher horizontal stress,more frequent occurrence of competent rock layers,etc.).Mining depth,dislocations and mining remnants in coal seams are the most important factors responsible for the occurrence of rockburst hazards.Longwall mining next to the mining edges of neighbouring coal seams is particularly disadvantageous.The levels of rockburst hazards are minimised via the use of rockburst prevention methods.One active prevention method is torpedo blasting in roof rocks.Torpedo blastings are performed in order to decrease local stress concentrations in rock masses and to fracture the roof rocks to prevent or minimise the impact of high-energy tremors on excavations.The estimation of the effectiveness of torpedo blasting is particularly important when mining is under difficult geological and mining conditions.Torpedo blasting is the main form of active rockburst prevention in the assigned colliery in the Polish part of the USCB.The effectiveness of blasting can be estimated using the seismic effect method,in which the seismic monitoring data and the mass of explosives are taken into consideration.The seismic effect method was developed in the Czech Republic and is always being used in collieries in the Czech part of the coal basin.Now,this method has been widely adopted for our selected colliery in the Polish part of the coal basin.The effectiveness of torpedo blastings in the faces and galleries of the assigned longwall in coal seam 506 has been estimated.The results show that the effectiveness of torpedo blastings for this longwall was significant in light of the seismic effect method,which corresponds to the in situ observations.The seismic effect method is regularly applied to estimating the blasting effectiveness in the selected colliery.
文摘The aim of the present study is to observe the preventive effects of moxibustion onseniIe anemia in rats and certify the anti-aging effects of moxibustion. The results show that thehemoglobin in 20 months old rats is lower than that in young rats, and the osmotic fragility and thehematocrit are higher than those in young rats. The hernoglobin in moxibustion group rats is signifi-cantly higher than that in old group, and the osmotic fragility and the hematocrit are markedly lowerthan those in old group, suggesting that moxibustion can delay the age-related changes of erythrocytein the rat and decrease the incidence rate of senile anemia of rat.

文摘Objective: To evaluate the role of prevention and control strategies for nosocomial infection in a tertiary teaching hospital during the sudden outbreak of Corona Virus Disease 2019 (COVID-19). Methods: The hospital initiated an emergency plan involving multi-departmental defense and control. It adopted a series of nosocomial infection prevention and control measures, including strengthening pre-examination and triage, optimizing the consultation process, improving the hospital’s architectural composition, implementing graded risk management, enhancing personal protection, and implementing staff training and supervision. Descriptive research was used to evaluate the short-term effects of these in-hospital prevention and control strategies. The analysis compared changes in related evaluation indicators between January 24, 2020 and February 12, 2020 (Chinese Lunar New Year’s Eve 2020 to lunar January 19) and the corresponding lunar period of the previous year. Results: Compared to the same period last year, the outpatient fever rate increased by 1.85-fold (P P Conclusion: The nosocomial infection prevention and control strategies implemented during this specific period improved the detection and control abilities for the COVID-19 source of infection and enhanced the compliance with measures. This likely contributed significantly to avoiding the occurrence of nosocomial infection.
文摘Objective: to explore the intervention effect of severe patients supplemented with preventive enteral nutrition care and effect on the prevention of enteral nutrition diarrhea. Methods: the participants were 100 severe patients treated in the hospital in the period from January, 2021 to June, 2022. The digital parity method was the grouping method of two groups. The care plan was routine enteral nutrition care and preventive enteral nutrition care, respectively, and the preventive effect of the two groups after the intervention was compared. Results: after the occurrence of diarrhea symptoms, the observation group was lower than the control group, P 0.05;the observation group was P 0.05, and the observation group was P 0.05. After comparing the quality of life, the observation group was significantly higher than the control group, P 0.05. Conclusion: the preventive enteral nutrition care mode can not only reduce the risk of diarrhea symptoms, but also improve the various nutritional indicators, which is conducive to increasing the recognition of patients for clinical nursing services and promoting their early health recovery, which is worth promoting.
文摘Objective: to investigate the effect of fluoride containing gel on preventing enamel demineralization and improving enamel lesion during orthodontic treatment. Methods: 60 patients were randomly divided into reference group and study group (30 patients in each group) and received orthodontic treatment in our hospital from July 2020 to July 2021. After orthodontic treatment, the patients in the reference group were instructed to apply fluoride toothpaste. The patients in the research group were treated with fluoride gel smearing once a month on the basis of fluoride toothpaste. Then, the probability of enamel demineralization was compared and the impact on the degree of enamel damage was analyzed. Results: there was no significant difference between the clinical efficacy A and the study group (P>0.05). After 6 and 12 months of treatment, the incidence of enamel demineralization, enamel demineralization index, DD detection value, and the degree of enamel damage in the study group were lower than those in the reference group, and the teeth masticatory efficiency and tooth beauty scores were higher than those in the reference group, with statistical significance (P〈0.05). Conclusion: the application of fluoride containing gel in orthodontic treatment can not only effectively prevent the occurrence of enamel demineralization, but also reduce the degree of enamel damage, and promote the improvement of chewing efficiency and aesthetics of teeth. It is worth further application and promotion.
文摘Objective:To explore the preventive effect of comprehensive nursing intervention on arteriovenous fistula failure in patients in the hemodialysis room.Methods:82 patients with arteriovenous fistula in the hemodialysis chamber treated in our hospital from July 2022 to October 2023 were selected as the research subjects.The random number table method divided them into a control group and an experimental group of 41 cases each.The control group received general nursing intervention measures,while the experimental group underwent comprehensive nursing intervention.The incidence of complications(internal fistula failure,bleeding,thrombosis,infection),psychological emotions(SAS scale,SDS scale),quality of life(physical pain,physiological function,emotional function,social function),and nursing satisfaction(very satisfied,basically satisfied,satisfied,dissatisfied)were compared between the two groups of patients.Results:The incidence of complications in the experimental group(4,9.76%)was significantly lower than that in the control group(29,70.73%);the SAS scores and SDS scores of the patients in the experimental group after intervention were both lower than those in the control group;the quality of life score(physical pain,physiological function,emotional function,and social function)was all higher than those of the control group;the post-intervention nursing satisfaction of the experimental group(40,97.57%)was also significantly higher than that of the control group(29,73.17%);and the listed differences were statistically significant(P<0.01).Conclusion:For patients with hemodialysis ventricular arteriovenous fistula failure,comprehensive nursing intervention can reduce the incidence of complications,relieve anxiety and stress,improve quality of life and nursing satisfaction,and achieve better preventive effects.
文摘Objective: to analyze the effect of fluoride varnish on the prevention of children's first permanent molar caries and the incidence of dental caries, and to provide reference for the prevention of children's dental caries. Methods: a total of 310 children with eruption of mandibular first molars who underwent routine physical examination in kindergartens in this city from August 2018 to October 2019 were randomly selected as research objects. They were randomly divided into the control group and the study group with 155 children in each group receiving different oral care measures, and the situation in the next 24 months was tracked and studied. The children in the control group were given routine oral care such as brushing their teeth in the morning and evening and gargling after meals, while the children in the study group were given oral care based on this. The occurrence of caries of the first permanent molars in the two groups at 6, 12, 18 and 24 months after physical examination and the preventive effect of the two kinds of care measures were observed and compared. Results: after 6 months of nursing, there was no significant difference in the incidence of caries between the two groups (1.83%vs2.17%) (P > 0.05). In the last three stages, the incidence of dental caries in children showed an upward trend. The incidence rates in the study group were 6.33%, 9.67% and 13.17% respectively, and the incidence rates in the control group were 14.33%, 19.50% and 24.83%, respectively. Compared with the control group, the incidence rates of dental caries in the study group were lower than those in the control group at each stage (p < 0.05). In addition, 6 months after nursing, there was no significant difference between the two groups (P > 0.05). In the last three stages, the average caries and caries surface of the two groups increased gradually, but the average caries and caries surface of the study group were lower at each stage (P < 0.05). Conclusion: fluorine protective paint has good preventive effect on children's first permanent molar caries, and the incidence of dental caries is low within two years, which is worthy of wide promotion.
文摘Introduction: This study aimed to identify road safety interventions implemented in Africa and to analyze their effectiveness in reducing road crashes, injuries, disabilities and deaths. Materials and Methods: This is a systematic review including articles relating to the evaluation of road safety interventions implemented in Africa that were searched on electronic databases: PubMed, Scopus, Lissa, Google Scholar, and African Journals Online. Selection of articles and data extraction was conducted by two pairs of reviewers. Data quality was checked according to the type of study. A qualitative analysis of the data was carried out and a narrative approach was adopted to describe and synthesize the results. Results: A total of twenty-nine articles were selected including one cross-sectional study, seven time series, twenty-one quasi-experimental studies of which six randomised and fifteen non-randomised studies. The type of interventions evaluated was aimed at all types of users and was based on different interventions such as institutional strengthening, law enforcement, awareness raising, training or user education, vehicle maintenance and infrastructure improvements. For fourteen studies all the expected indicators had changed favourably and for twelve the indicators had partially changed. The studies that showed significant change were institutional strengthening, law enforcement, awareness raising, training, or user education interventions, development of Uber transport services, distribution of equipment, and a combination of interventions. Conclusion: This situation is indicative of insufficient policy investment in research but also in the field of road safety in general.

文摘Objective: A mesh Meta-analysis was used to evaluate the effectiveness of four warm-up exercises to prevent knee injuries in juvenile soccer players. Method: They are a randomized controlled trial (RCT) on FIFA 11+ integrated warm-up, FIFA 11+ Kids integrated warm-up, and neuromuscular training (NMT) warm-up for the prevention of knee joint in juvenile soccer players by a computer search of CNKI, CBMdisc, WanFangdata, Pubmed, Web of science, and SPORTDicus database. The search period was from the establishment of each database to February 2022. Two investigators screened the literature, extracted data, and assessed risk bias for the included studies according to the pre-defined inclusion and exclusion criteria, and finally analyzed the data using Stata 14.0 software and OpenBUGS software. Results: A total of 10 RCT studies with 17,143 subjects, spanning the age range of 7 to 19 years, were included. The results of the reticulated Meta-analysis showed that all three warm-up modalities were effective in reducing the incidence of knee injuries in junior soccer players compared to conventional warm-up, with the optimality in descending order of FIFA 11+ Kids comprehensive warm-up (SUCRA = 85.3), neuromuscular training warm-up (SUCRA = 66.7), and FIFA 11+ combined warm-up (SUCRA = 44). Conclusion: The FIFA 11+ Kids comprehensive warm-up is the most effective warm-up exercise for the prevention of knee injuries in junior and child soccer players, but the above findings need further validation due to the quantity and quality of the literature and the quality of the evidence.
