Inspection activities were performed at regular intervals. Once the system was identified to be at defective state by inspection,a maintenance decision needed to be made that whether to replace the defective system immediately or wait till the preset APR time. So a threshold was introduced into the model and called as inspection-based preventive replacement( IPR) threshold. If the distance from the defect identification point to the APR time was longer than the threshold, a preventive replacement( PR) action was made; otherwise PR action was to wait till the APR time. Two models were proposed and compared,and a numerical example was conducted to illustrate the applicability of the model.展开更多

Acute abdomen during pregnancy represents one of the most challenging critical conditions in obstetrics, with its morbidity and mortality rates consistently ranking among the leading causes of maternal death. In recent years, with population aging and an increasing proportion of advanced-age pregnancies, the incidence of pregnancy-associated acute abdomen has shown an upward trend. This study systematically analyzes the primary etiologies, clinical characteristics, and therapeutic strategies of acute abdomen during pregnancy while exploring the effectiveness of preventive measures. Research indicates that pregnancy-specific anatomical and physiological changes, environmental factors, and genetic background play crucial roles in disease occurrence. The establishment of a comprehensive prevention system, including pre-pregnancy assessment, gestational monitoring, and emergency response planning, can significantly reduce incidence rates. Multi-center clinical data analysis demonstrates that early identification of risk factors, standardized prenatal examinations, and establishment of rapid diagnosis and treatment channels are key to improving successful treatment rates. This study provides new insights and methodologies for reducing the incidence and mortality rates of pregnancy-associated acute abdomen, holding significant implications for improving maternal and fetal outcomes.展开更多

OBJECTIVE： To observe the effects of preventive acupuncture or moxibustion at the Guanyuan point on interleukin-2 （IL-2） and its receptor （IL-2R mRNA） levels in hypothalamus, serum, and uterus of menopausal rats. DESIGN： Randomized control animal experiment. SETTING： School of Acupuncture and Moxibustion, Beijing University of Chinese Medicine. MATERIALS： This study was performed at the Laboratory of Beijing University of Chinese Medicine from November 2004 to July 2005. The vaginal smear method was used to determine the estrus cycle of 9.5-month-old Sprague Dawley （SD） female rats. Three continuous estrus cycles were measured, and 160 rats with estrus cycle disorder, weighing （300 _＋ 20） g, were included in this study. The rats were randomly divided into four groups： preventive acupuncture group （n =48）, preventive moxibustion group （n =48）, model groups （n =48）, and 10-month-old group （n =16）. Sixteen 3.5-month-old healthy SD female rats, weighing （240 ± 20） g, were also assigned to the young group. All rats were clean grade and were purchased from the Laboratory Animal Center, Beijing University of Chinese Medicine. The experiment was in accordance with animal ethics standards. METHODS： Acupuncture was applied to the preventive acupuncture group at 10 months of age. The needle was inserted upward and perpendicularly two fen to a point that was two fen below the Guanyuan point. The rats freely moved around during needle retention （20 minutes）. Acupuncture was administered twice a week and continued for eight weeks. A moxa cone （small） moxibustion was applied to the preventive moxibustion group at 10 months of age. The rats were caught gently and kept at the same position as the preventive acupuncture group. The moxa cone was ignited and held to the Guanyuan point directly. Only one moxa cone was used each time. After moxibustion, the local skin turned slightly red. Moxibustion was used twice a week and continued for eight weeks. Nothing except gently catching and lying was administered to the model group and the young group. MAIN OUTCOME MEASURES： Radioimmunoassay, in situ hybridization, and similar methods were employed to detect IL-2 in serum and the uterus, as well as IL-2R mRNA expression in the hypothalamus and uterus arcuate nuclei, of the preventive acupuncture group, preventive moxibustion group, model groups （at 12, 14, and 16 months）, 10 month old group （at 10 months）, and the young group （at 4 months）. RESULTS： All 176 rats were included in the final analysis. （1） IL-2R mRNA： IL-2R mRNA expression decreased significantly in the uterus of 12-, 14-, and 16-month-old model groups and in the hypothalamus of 14- and 16-month-old model groups （P 〈 0.05-0.01）. Compared to the same month-aged model groups, the expression of IL-2R mRNA increased significantly in the hypothalamus and uterus of 16-month-old preventive acupuncture or moxibustion groups （P 〈 0.05-0.01）.（2） IL-2：IL-2 in serum of 12- and 14-month-old model groups and in the uterus of 12-, 14-, and 16-month-old model groups decreased significantly compared to the young group （P 〈 0.05-0.01）. IL-2 serum levels increased significantly in the 16-month-old group with preventive moxibustion; in addition, IL-2 expression levels increased significantly in the uterus of the 12-month-old group with preventive moxibustion, as well as the 12- and 16-month-old groups with preventive acupuncture （P 〈 0.05-0.01）. CONCLUSION： As a rat ages and becomes menopausal, IL-2R mRNA expression in the hypothalamus and uterus, as well as IL-2 levels in the serum and uterus, decrease. However, preventive acupuncture and preventive moxibustion can repress the decrease to some extent. This effect is even greater in the late stages of menopause （16-month-old rats）.展开更多

The fertilized eggs of golden trout were randomly divided into 13 groups, each group with two parallels of 1 000 eggs. Drugs at high,medium and low concentration were respectively used to immerse the fertilized eggs35 min for disinfection once a day. The numbers of live and dead eggs were recorded each day before disinfection and the numbers of survival eyed eggs were counted in each experimental group after finishing the whole test. The results indicated that all of four kinds of drugs used here had a certain effect on prevention and control of saprolegniasis during hatching of fertilized eggs of golden trout, and also showed a correlation between the concentrations and effects. After the selection of several drugs, we found that group B-medium, C-medium and D-high exhibited the most remarkable effects on control of saprolegniasis. However, careful consideration should be given to chemical drugs residues and their potential hazard to the eyed eggs. Therefore, Chinese herbal compound B was suggested to be used for prevention and control of saprolegniasis to achieve the healthy aquaculture. And the concentration and operation time of Chinese herbal compound B should be strictly controlled when used in disinfection of fertilized eggs.展开更多

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.展开更多

It has achieved great benefits. For women with gynecological diseases, pelvic inflammatory disease patients accounted for a large proportion. Due to the lack of specificity in diagnosis and treatment, the condition is lingering and difficult to cure, so it seriously reduces the quality of life of women, thus affecting the harmony of family and society. From the perspective of prevention, according to the characteristics of each stage of the disease, this paper put forward substantive prevention suggestions and targeted treatment methods, ensuring preventing before disease, preventing progress after disease, and preventing reoccurring after recovery. It has important practical significance for the prevention and treatment of pelvic inflammatory diseases, as well as the development and inheritance of traditional Chinese medicine.展开更多

It is generally seen as an imperfect maintenance action which has a chief influence on the maintenance strategy. In order to model the maintenance effect of servicing, this study analyzes the deterioration characteristics of system under scheduled servicing. And then the deterioration model is established from the failure mechanism by compound Poisson process. On the basis of the system damage value and failure mechanism, the failure rate refresh factor is proposed to describe the maintenance effect of servicing. A maintenance strategy is developed which combines the benefits of scheduled servicing and preventive maintenance. Then the optimization model is given to determine the optimal servicing period and preventive maintenance time, with an objective to minimize the system expected life-cycle cost per unit time and a constraint on system survival probability for the duration of mission time. Subject to mission time, it can control the ability of accomplishing the mission at any time so as to ensure the high dependability. An example of water pump rotor relating to scheduled servicing is introduced to illustrate the failure rate refresh factor and the proposed maintenance strategy. Compared with traditional methods, the numerical results show that the failure rate refresh factor can describe the maintenance effect of servicing more intuitively and objectively. It also demonstrates that this maintenance strategy can prolong the lifetime, reduce the total lifetime maintenance cost and guarantee the dependability of system.展开更多

Two PM techniques, periodic PM and sequential PM, are considered. Whenever one of the units reaches its reliability threshold, a PM action has to be performed on that unit. At that time the whole system has to be stopped and PM opportunities arise for the other unitsof the system. An optimal PM practice is determined by maximizing the short-term cumulative opportunistic maintenance (OM) cost savings for the whole system. Numerical examples are given to show how this approach works. Finally, a comparison between the proposed PM policy and the other policies is given.展开更多

The treatment approaches presented above include adjuvant intrahepatic arterial infusion chemotherapy, systemic chemotherapy, neoadjuvant chemotherapy, and immunotherapy. Although no standard treatment has been established, several approaches present promising results, which are both effective and tolerable in post-hepatectomy patients. Intrahepatic arterial infusion chemotherapy should be regarded as effective and tolerable and it increases overall survival (OS) and disease free survival (DFS) of patients, while 5-fluorouracil-based systemic chemotherapy has not shown any significant survival benefit. Fortunately chemotherapy combined with hepatic arterial infusion and intravenous infusion has shown OS and DFS benefit in many researches. Few neoadjuvant RCT studies have been conducted to evaluate its effect on prolonging survivals although many retrospective studies and case reports are published in which unresectable colorectal liver metastases are downstaged and made resectable with neoadjuvant chemotherapy. Liver resection supplemented with immunotherapy is associated with optimal results; however, it is also questioned by others. In conclusion, several adjuvant approaches have been studied for their efficacy on recurrence after hepatectomy for liver metastases from colorectal cancer (CRC), but multi-centric RCT is still needed for further evaluation on their efficacy and systemic or local toxicities. In addition, new adjuvant treatment should be investigated to provide more effective and tolerable methods for the patients with resectable hepatic metastases from CRC.展开更多

But so far, there are fewer and less conclusive data concerning its pathogenic mechanism in detail. In current study, the toxicity of DMAc was firstly investigated on human normal hepatocytes （LO-2）, using a series of molecular biology measurements to ananlyze the effect and mechanism of DMAc-induced hepatic cell injury and explore effective prophylactic measures. We found that DMAc triggered LO-2 apoptosis in a obviously dose-dependent manner, caused by increased ROS generation and activation of Bcl-2 pathway. Significantly, glutathione （GSH） rather than vitamin C （Vit C） could partially inhibit DMAc-induced apoptosis thus showing potential as a effective precaution for workers.展开更多

文摘Acute abdomen refers to a sudden onset of severe abdominal pain that may require urgent surgical intervention, while biliary system diseases encompass disorders affecting the gallbladder, bile ducts, and associated structures. Acute abdomen during pregnancy represents one of the most challenging critical conditions in obstetrics, with its morbidity and mortality rates consistently ranking among the leading causes of maternal death. In recent years, with population aging and an increasing proportion of advanced-age pregnancies, the incidence of pregnancy-associated acute abdomen has shown an upward trend. This study systematically analyzes the primary etiologies, clinical characteristics, and therapeutic strategies of acute abdomen during pregnancy while exploring the effectiveness of preventive measures. Research indicates that pregnancy-specific anatomical and physiological changes, environmental factors, and genetic background play crucial roles in disease occurrence. The establishment of a comprehensive prevention system, including pre-pregnancy assessment, gestational monitoring, and emergency response planning, can significantly reduce incidence rates. Multi-center clinical data analysis demonstrates that early identification of risk factors, standardized prenatal examinations, and establishment of rapid diagnosis and treatment channels are key to improving successful treatment rates. This study provides new insights and methodologies for reducing the incidence and mortality rates of pregnancy-associated acute abdomen, holding significant implications for improving maternal and fetal outcomes.
文摘Prophylactic fixation(ProFix)of the proximal femur in elderly patients with osteoporosis presents a forward-thinking approach to preventing debilitating fractures and their associated complications.By addressing fracture risk before an injury occurs,ProFix has the potential to enhance patient outcomes,promote long-term mobility,and reduce healthcare costs.Early intervention in individuals at high risk can significantly lower hospital admissions,shorten recovery periods,and preserve independence,mitigating challenges such as chronic pain and reduced life expectancy.Given the high prevalence of undiagnosed osteoporosis,prioritising early risk assessment and targeted prevention is essential.Advancements in minimally invasive surgical techniques and safer anaesthesia methods further support ProFix as a feasible and effective strategy to decrease fracturerelated morbidity,improve overall patient well-being,and optimise the use of healthcare resources.This opinion review details the evidence supporting this concept,its efficacy,the challenges in its implementation,and a strategic plan for future implementation.

文摘BACKGROUND： Previous studies have indicated preventive acupuncture and moxibustion at the Guanyuan point have positive effects on the immune system of menopausal rats. OBJECTIVE： To observe the effects of preventive acupuncture or moxibustion at the Guanyuan point on interleukin-2 （IL-2） and its receptor （IL-2R mRNA） levels in hypothalamus, serum, and uterus of menopausal rats. DESIGN： Randomized control animal experiment. SETTING： School of Acupuncture and Moxibustion, Beijing University of Chinese Medicine. MATERIALS： This study was performed at the Laboratory of Beijing University of Chinese Medicine from November 2004 to July 2005. The vaginal smear method was used to determine the estrus cycle of 9.5-month-old Sprague Dawley （SD） female rats. Three continuous estrus cycles were measured, and 160 rats with estrus cycle disorder, weighing （300 _＋ 20） g, were included in this study. The rats were randomly divided into four groups： preventive acupuncture group （n =48）, preventive moxibustion group （n =48）, model groups （n =48）, and 10-month-old group （n =16）. Sixteen 3.5-month-old healthy SD female rats, weighing （240 ± 20） g, were also assigned to the young group. All rats were clean grade and were purchased from the Laboratory Animal Center, Beijing University of Chinese Medicine. The experiment was in accordance with animal ethics standards. METHODS： Acupuncture was applied to the preventive acupuncture group at 10 months of age. The needle was inserted upward and perpendicularly two fen to a point that was two fen below the Guanyuan point. The rats freely moved around during needle retention （20 minutes）. Acupuncture was administered twice a week and continued for eight weeks. A moxa cone （small） moxibustion was applied to the preventive moxibustion group at 10 months of age. The rats were caught gently and kept at the same position as the preventive acupuncture group. The moxa cone was ignited and held to the Guanyuan point directly. Only one moxa cone was used each time. After moxibustion, the local skin turned slightly red. Moxibustion was used twice a week and continued for eight weeks. Nothing except gently catching and lying was administered to the model group and the young group. MAIN OUTCOME MEASURES： Radioimmunoassay, in situ hybridization, and similar methods were employed to detect IL-2 in serum and the uterus, as well as IL-2R mRNA expression in the hypothalamus and uterus arcuate nuclei, of the preventive acupuncture group, preventive moxibustion group, model groups （at 12, 14, and 16 months）, 10 month old group （at 10 months）, and the young group （at 4 months）. RESULTS： All 176 rats were included in the final analysis. （1） IL-2R mRNA： IL-2R mRNA expression decreased significantly in the uterus of 12-, 14-, and 16-month-old model groups and in the hypothalamus of 14- and 16-month-old model groups （P 〈 0.05-0.01）. Compared to the same month-aged model groups, the expression of IL-2R mRNA increased significantly in the hypothalamus and uterus of 16-month-old preventive acupuncture or moxibustion groups （P 〈 0.05-0.01）.（2） IL-2：IL-2 in serum of 12- and 14-month-old model groups and in the uterus of 12-, 14-, and 16-month-old model groups decreased significantly compared to the young group （P 〈 0.05-0.01）. IL-2 serum levels increased significantly in the 16-month-old group with preventive moxibustion; in addition, IL-2 expression levels increased significantly in the uterus of the 12-month-old group with preventive moxibustion, as well as the 12- and 16-month-old groups with preventive acupuncture （P 〈 0.05-0.01）. CONCLUSION： As a rat ages and becomes menopausal, IL-2R mRNA expression in the hypothalamus and uterus, as well as IL-2 levels in the serum and uterus, decrease. However, preventive acupuncture and preventive moxibustion can repress the decrease to some extent. This effect is even greater in the late stages of menopause （16-month-old rats）.

文摘In order to screen the effective preventive drugs for saprolegniasis occurred during hatching of the fertilized eggs of golden trout, effects of two kinds of self-made Chinese herbal compounds（AB） and two kinds of chemical bactericides（peroxyacetic acid andhydrogen peroxide, CD） with three disinfection concentrations were compared in this study. The fertilized eggs of golden trout were randomly divided into 13 groups, each group with two parallels of 1 000 eggs. Drugs at high,medium and low concentration were respectively used to immerse the fertilized eggs35 min for disinfection once a day. The numbers of live and dead eggs were recorded each day before disinfection and the numbers of survival eyed eggs were counted in each experimental group after finishing the whole test. The results indicated that all of four kinds of drugs used here had a certain effect on prevention and control of saprolegniasis during hatching of fertilized eggs of golden trout, and also showed a correlation between the concentrations and effects. After the selection of several drugs, we found that group B-medium, C-medium and D-high exhibited the most remarkable effects on control of saprolegniasis. However, careful consideration should be given to chemical drugs residues and their potential hazard to the eyed eggs. Therefore, Chinese herbal compound B was suggested to be used for prevention and control of saprolegniasis to achieve the healthy aquaculture. And the concentration and operation time of Chinese herbal compound B should be strictly controlled when used in disinfection of fertilized eggs.
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With a history of more than two thousand years, the theory of preventative treatment has been closely followed by the development of modern medical theories on the basis of inheritance by medical experts in the past dynasties, which has been constantly improved and enriched, and deeply applied in the prevention and treatment of serious and multiple diseases. It has achieved great benefits. For women with gynecological diseases, pelvic inflammatory disease patients accounted for a large proportion. Due to the lack of specificity in diagnosis and treatment, the condition is lingering and difficult to cure, so it seriously reduces the quality of life of women, thus affecting the harmony of family and society. From the perspective of prevention, according to the characteristics of each stage of the disease, this paper put forward substantive prevention suggestions and targeted treatment methods, ensuring preventing before disease, preventing progress after disease, and preventing reoccurring after recovery. It has important practical significance for the prevention and treatment of pelvic inflammatory diseases, as well as the development and inheritance of traditional Chinese medicine.

文摘Servicing is applied periodically in practice with the aim of restoring the system state and prolonging the lifetime. It is generally seen as an imperfect maintenance action which has a chief influence on the maintenance strategy. In order to model the maintenance effect of servicing, this study analyzes the deterioration characteristics of system under scheduled servicing. And then the deterioration model is established from the failure mechanism by compound Poisson process. On the basis of the system damage value and failure mechanism, the failure rate refresh factor is proposed to describe the maintenance effect of servicing. A maintenance strategy is developed which combines the benefits of scheduled servicing and preventive maintenance. Then the optimization model is given to determine the optimal servicing period and preventive maintenance time, with an objective to minimize the system expected life-cycle cost per unit time and a constraint on system survival probability for the duration of mission time. Subject to mission time, it can control the ability of accomplishing the mission at any time so as to ensure the high dependability. An example of water pump rotor relating to scheduled servicing is introduced to illustrate the failure rate refresh factor and the proposed maintenance strategy. Compared with traditional methods, the numerical results show that the failure rate refresh factor can describe the maintenance effect of servicing more intuitively and objectively. It also demonstrates that this maintenance strategy can prolong the lifetime, reduce the total lifetime maintenance cost and guarantee the dependability of system.

文摘This paper proposes a dynamic opportunistic preventive maintenance (PM) optimization policy for multi-unit series systems by integrating multi PM techniques. Two PM techniques, periodic PM and sequential PM, are considered. Whenever one of the units reaches its reliability threshold, a PM action has to be performed on that unit. At that time the whole system has to be stopped and PM opportunities arise for the other unitsof the system. An optimal PM practice is determined by maximizing the short-term cumulative opportunistic maintenance (OM) cost savings for the whole system. Numerical examples are given to show how this approach works. Finally, a comparison between the proposed PM policy and the other policies is given.
文摘To review the preventive approaches for recurrence after curative resection of hepatic metastases from colorectal carcinoma, we have summarized all available publications reporting randomized control trials (RCTs) covered in PubMed. The treatment approaches presented above include adjuvant intrahepatic arterial infusion chemotherapy, systemic chemotherapy, neoadjuvant chemotherapy, and immunotherapy. Although no standard treatment has been established, several approaches present promising results, which are both effective and tolerable in post-hepatectomy patients. Intrahepatic arterial infusion chemotherapy should be regarded as effective and tolerable and it increases overall survival (OS) and disease free survival (DFS) of patients, while 5-fluorouracil-based systemic chemotherapy has not shown any significant survival benefit. Fortunately chemotherapy combined with hepatic arterial infusion and intravenous infusion has shown OS and DFS benefit in many researches. Few neoadjuvant RCT studies have been conducted to evaluate its effect on prolonging survivals although many retrospective studies and case reports are published in which unresectable colorectal liver metastases are downstaged and made resectable with neoadjuvant chemotherapy. Liver resection supplemented with immunotherapy is associated with optimal results; however, it is also questioned by others. In conclusion, several adjuvant approaches have been studied for their efficacy on recurrence after hepatectomy for liver metastases from colorectal cancer (CRC), but multi-centric RCT is still needed for further evaluation on their efficacy and systemic or local toxicities. In addition, new adjuvant treatment should be investigated to provide more effective and tolerable methods for the patients with resectable hepatic metastases from CRC.

文摘N,N-Dimethylacetamide （DMAc） is a widely used organic solvent in modern chemical industry with low to moderate hepatotoxicity to occupational health of employees. But so far, there are fewer and less conclusive data concerning its pathogenic mechanism in detail. In current study, the toxicity of DMAc was firstly investigated on human normal hepatocytes （LO-2）, using a series of molecular biology measurements to ananlyze the effect and mechanism of DMAc-induced hepatic cell injury and explore effective prophylactic measures. We found that DMAc triggered LO-2 apoptosis in a obviously dose-dependent manner, caused by increased ROS generation and activation of Bcl-2 pathway. Significantly, glutathione （GSH） rather than vitamin C （Vit C） could partially inhibit DMAc-induced apoptosis thus showing potential as a effective precaution for workers.

文摘In the process of green and smart mine construction under the context of carbon neutrality,China's coal safety situation has been continuously improved in recent years.In order to recognize the development of coal production in China and prepare for future monitoring and prevention of safety incidents,this study mainly elaborated on the basic situation of coal resources and national mining accidents over the past five years(2017-2021),from four dimensions(accident level,type,region,and time),and then proposed the preventive measures based on accident statistical laws.The results show that the storage of coal resources has obvious geographic characteristics,mainly concentrated in the Midwest,with coal resources in Shanxi and Shaanxi accounting for about 49.4%.The proportion of coal consumption has dropped from 70.2%to 56%between 2011 and 2021,but still accounts for more than half of the all.Meanwhile,the accident-prone areas are positively correlated with the amount of coal production.Among different levels of coal mine accidents,general accidents had the highest number of accidents and deaths,with 692 accidents and 783 deaths,accounting for 87.6%and 54.64%respectively.The frequency of roof,gas,and transportation accidents is relatively high,and the number of single fatalities caused by gas accidents is the largest,about 4.18.In terms of geographical distribution of accidents,the safety situation in Shanxi Province is the most severe.From the time distribution of coal mine accidents,the accidents mainly occurred in July and August,and rarely occurred in February and December.Finally,the"4+4"safety management model is proposed,combining the statistical results with coal production in China.Based on the existing health and safety management systems,the manage-ments are divided into four sub-categories,and more specific measures are suggested.
文摘AIM:To investigate gastric cancer screening and preventive behaviors among the relatives of patients with gastric cancer[i.e.,gastric cancer relatives(GCRs)].METHODS:We examined the Korean National Health and Nutrition Examination Survey 2005(KNHANESⅢ) database and compared the gastric cancer screening and preventive behaviors of GCRs(n=261)with those of non-GCRs(n=454)and controls without a family history of cancer(n=2842).RESULTS:The GCRs were more likely to undergo gastric cancer screening compared with the control group(39.2%vs 32.3%,adjusted odds ratio:1.43,CI:1.05-1.95),although the absolute screening rate was low.Dietary patterns and smoking rates did not differ significantly between the groups,and a high proportion of GCRs reported inappropriate dietary habits(i.e.,approximately 95%consumed excessive sodium,30% were deficient in vitamin C,and 85%were deficient in dietary fiber).CONCLUSION:The gastric cancer screening and preventive behaviors of GCRs have yet to be improved.To increase awareness among GCRs,systematic family education programs should be implemented.
