Objective:To investigate the prevalence and influencing factors of frailty among older adults diagnosed with non-ST-segment elevation acute coronary syndrome(NSTE-ACS).Methods:We conducted a cross-sectional study involving patients aged 65 years and older with NSTE-ACS, who were admitted to the Cardiology Center and the Department of Geriatrics at Beijing Friendship Hospital, Capital Medical University, between January 2020 and November 2021.Patients were categorized into non-frail, pre-frail, and frail groups based on the FRAIL scale.We collected clinical data, including general health conditions, comorbidities, laboratory results, treatments, and comprehensive geriatric assessments.Logistic regression analysis was employed to identify the influencing factors associated with frailty and pre-frailty in older adults with NSTE-ACS.Results:A total of 528 patients with NSTE-ACS were included in the study, comprising 308 males(58.3%)and 220 females(41.7%). The age range of participants was from 65 to 90 years, with a median age of 72(68, 76)years.The prevalence of frailty among older adults with NSTE-ACS was 11.4%(60/528), while pre-frailty was observed in 51.9%(274/528), and non-frailty in 36.7%(194/528). Compared to the non-frail and pre-frail groups, patients in the frail group were older, had a higher proportion of females, exhibited a greater prevalence of chronic diseases, and presented with elevated inflammatory markers.Additionally, frail patients demonstrated poorer nutritional status and reduced functional ability(all P<0.005). Risk factors for frailty in older adults with NSTE-ACS included older age( OR=1.110, 95% CI: 1.032-1.194, P=0.005), diabetes( OR=2.489, 95% CI: 1.091-5.679, P=0.030), cerebrovascular disease ( OR=4.151, 95% CI: 1.660-10.384, P=0.002), chronic kidney disease ( OR=42.874, 95% CI: 3.957-464.513, P=0.002), and elevated white blood cell levels( OR=1.424, 95% CI: 1.125-1.802, P=0.003). Conversely, being male( OR=0.252, 95% CI: 0.105-0.604, P=0.002)was identified as a protective factor against frailty in this patient population.For pre-frail older adults with NSTE-ACS, identified risk factors included diabetes( OR=1.882, 95% CI: 1.199-2.955, P=0.006), cerebrovascular disease( OR=1.938, 95% CI: 1.176-3.195, P=0.009), and chronic kidney disease ( OR=12.137, 95% CI: 1.536-95.934, P=0.018). Similarly, being male( OR=0.601, 95% CI: 0.376-0.961, P=0.033)was also a protective factor for pre-frailty in older adults with NSTE-ACS. Conclusions:The prevalence of frailty and pre-frailty among older adults with NSTE-ACS is notably high.Common risk factors for frailty and pre-frailty in this population include female gender, diabetes, cerebrovascular disease, and chronic kidney disease.

To summarize the research progress and to discuss current drug supplement status of radiation preventive and curative drugs,which would provide fresh thoughts for nuclear emergency rescue and therapy.Classification of clinically available and under-development radiation prevention and treatment drugs has been presented in terms of symptomatic and causative prevention and treatment drugs.We analyzed the necessity and challenges of establishing a supply system for radiation prevention and treatment and put forward counter measures and thinking prospects.Clinical stockpile of symptomatic drugs is relatively sufficient.Allopathic drugs are widely developed,however,the barriers between research and clinical translation and the inadequate market supply system pose greater demands and challenges to the provision of hospital radiation allopathic drugs.

Objective:To analyze the characteristics of the injury of knee ligament and cartilage in pediatric patients after acute traumatic lateral patellar dislocation based on magnetic resonance imaging (MRI). Methods:Clinical data of 68 pediatric patients with acute traumatic lateral patellar dislocation admitted to The Second Hospital of Tangshan from September,2020 to September,2023 were retrospectively analyzed. All children underwent MRI scan on knee joint. These children were divided into partial tear group (85 cases) and complete tear group (41 cases) according to injury degree. In addition,the location and characteristic of the medial patellofemoral ligament (MPFL) injury and cartilage injury were analyzed. Results:All 126 children had MPFL injury,including 85 cases of partial tear and 41 cases of complete tear. Among the partial tears,34 cases occurred only on the patellar side,14 cases only on the femoral side,9 cases only in the middle segment,and 28 cases had multiple-site injuries. Among the complete tears,27 cases occurred only on the patellar side,7 cases only on the femoral side,4 cases only in the middle segment,and 3 cases had multiple-site injuries. The number of each degree of partial MPFL injury was higher than that of complete injury,and the difference was statistically significant (x2=7.596,10.886,P<0.05). Among the 126 children,91 cases had VMO injury,and the degree of VMO injury was positively correlated with the degree of MPFL injury (r=0.339,P=0.006). Among the 126 children with acute traumatic lateral patellar dislocation,119 cases had osteochondral injury,with a total of 174 injured sites. The sites of grade 1 injury were mainly on the patellar side,while those of grades 2,3,and 4 injuries were mainly multiple-site injuries. Conclusion:Most of acute traumatic lateral patellar dislocation complicate MPFL injury and cartilage injury in pediatric patients,which mainly focus on patellar side of injury and multiple injury. There are no differences in injury site and degree between different genders. MPFL injury mostly complicates VMO injury,which injury degree is positively correlation with MPFL.

Objective:To explore the manifestations of magnetic resonance imaging(MRI)on acute traumatic lateral patellar dislocation of children and adolescents.Methods:MRI images of the affected side and healthy side of 110 children and adolescents with acute traumatic lateral patellar dislocation who were treated in the Second Hospital of Tangshan from July 2016 to April 2022 were retrospectively analyzed.The correlation of the medial patellofemoral ligament(MPFL)on the affected side between the tear location and tear degree was compared and analyzed.According to the cartilage injury grading system of international cartilage repair society(ICRS),the articular cartilage injury of affected side was divided into 4 grades,and the correlation between the articular cartilage injury grading and the articular cartilage injury location was compared and analyzed.Three methods of measuring patellar height,which included Insall-Salvati index(ISI),patellotrocheal index(PTI)and Caton-Deschamps index(CDI),were used to compare and analyze the differences of MRI data of patellar height between the affected side of knee joint and the healthy knee joint of pediatric children.Results:In 110 patients with MPFL injury,73 cases were partial tears and 37 cases were complete tears.There was significant difference in the injury at MPFL patellar attachment location between complete tears(22 cases)and partial tears(19 cases)(x2=11.740,P<0.05),and there was significant difference in MPFL multiple injury between partial tear(40 cases)and complete tear(8 cases)(x2=10.990,P<0.05).There were no significant differences in the injuries of MPFL middle segment and the origin of femur between partial tears and complete tears.There were 162 lesions in 110 cases with osteochondral injury,which included 55 lesions on the patellar side,33 lesions on the femur side and 74 multiple lesions according to the part of injury.There was significant difference between the location of osteochondral injury and injury grading(x2=38.153,P<0.05).The ISI,PTI and CDI on the affected side were significantly lower than those on the healthy side in pediatric patients with acute traumatic lateral patellar dislocation of children and adolescents(x2=30.853,12.586,19.656,P<0.05),respectively.Conclusion:The complete tears are more likely to occur in the injury of MPFL patellar attachment location of pediatric patients with acute traumatic lateral patellar dislocation of children and adolescents,while multiple injuries are more likely to be in partial tears.There is correlation between the articular cartilage injury grading and the articular cartilage injury location in pediatric patients.MRI is an important method to diagnose MPFL injury,which can provide more evidence for clinical treatment.

It is believed that the basic pathogenesis of oculomotor nerve paralysis （ONP） is qi and blood depletion and channel obstruction. Taking channel pattern differentiation as the core， it is recommended to use acupuncture mainly based on location， syndrome and channel deficiency-excess differentiation. Location and channel tropism differentiation mainly follows the principle of “where the channels and collaterals pass， the main treatment can reach”， and commonly uses acupuncture points on Dumai （督脉）， the hand Shaoyang （少阳） Sanjiao （三焦） channel， the hand Taiyang （太阳） small intestine channel， three yang channels of the foot， the hand Shaoyin （少阴） heart channel， the foot Jueyin （厥阴） liver channel， and others， and combines scalp acupuncture with electro-acupuncture to enhance channel stimulation. Pattern and channel tropism differentiation is to differentiate the entered channel according to clinical symptoms and zang-fu patterns. The differentiation of deficiency-excess should be payed attention to， and the principle of “supplementing the deficiency， and draining the excess” should be followed. The supplementing and draining method should be used rationally by considering the differences in the supplementing and draining acupoints themselves， as well as the actual condition of the patients. Simultaneously， it is suggested to combine manipulation and stimulation amount and effect in clinical practice.

Objective:To understand the mental health status of pregnant women in the third trimester of pregnancy, and explore the influencing factors.Methods:The general demographic information and pregnancy information of 575 pregnant women in the Chinese Pregnant Women Cohort Study were collected. The mental health status of pregnant women in the third trimester was investigated by using Edinburgh Postpartum Depression Scale, Self-Rating Anxiety Scale and University of California at Los Angeles. Multivariate unconditional logistic regression was used to analyze the influencing factors for mental health of pregnant women.Results:In the third trimester of pregnancy, the incidence of depression was 16.52%, the incidence of anxiety was 11.13%, and the incidence of feeling loneliness was 26.26%. Logistic regression analysis showed that compared with those with education level of junior high school below, those with education level of college or bachelor's degree ( OR=0.418, 95% CI: 0.184-0.950) and master's degree or above ( OR=0.116, 95% CI: 0.027-0.503) were less likely to feel loneliness. Pregnant women with higher annual family income (10 000 RMB yuan) were less likely to suffer from depression (≥20 vs. <10: OR=0.527, 95% CI: 0.279-0.998), anxiety (10-20 vs. <10: OR=0.363, 95% CI: 0.180-0.731; ≥20 vs. <10: OR=0.271, 95% CI: 0.132-0.554) and feeling loneliness (≥20 vs. <10: OR=0.477, 95% CI: 0.276-0.826). Conclusions:The education level and family income have impacts on the mental health status of pregnant women in the third trimester. Medical staff should give targeted psychological advice to pregnant women to improve their mental health status.

Objective To understand the status of economic burden of maternal health care of pregnant women in China, and to discuss the equity and accessibility of maternal health care during pregnancy among different regions and populations. Methods A total of 9 193 women during early pregnancy were recruited from the Chinese Pregnant Women Cohort Study between July 25, 2017 and November 26, 2018. Information on general condition and economic burden of maternal health care was surveyed. SPSS 25.0 software was used for statistical analysis. Results The median direct medical cost of maternity check-ups for pregnant women was 400 CNY per visit, and the median cost of lost work was 360 CNY per visit. The analysis of the results showed that the median medical expense was highest in pre-pregnant women with BMI <18.5kg/m² (P=0.008). The median medical expense was higher in urban residents than rural residents (P<0.001). Families with fewer members had higher direct medical expenses (P<0.001, P_trend=0.003). The higher the socioeconomic status was, the higher the direct medical expense was (P<0.001, P_trend=0.003). The cost of lost work was lower in pregnant women with higher socioeconomic status (P=0.025, P_trend=0.017). In addition, the medical expense was highest in women living in the eastern part of China (P<0.001). The direct medical expenses (P=0.002) and lost-time expenses of pregnant women in the North were higher than those in the South (P=0.013). Conclusion The problem of equity and accessibility of maternal health care still existed. It is recommended that relevant departments further improve maternal health care services and build a diversified healthcare service system to ensure maternal and child health and promote eugenics.
