Objective To analyze the current situation of unplanned reoperation in cardiac surgery and to discuss the management measures of unplanned reoperation.Methods The information of patients undergoing cardiac surgery in a class A tertiary comprehensive hospital during 2018-2022 was collected to analyze the incidence of unplanned reoperation,major ca uses,disease types,surgica l moda lities and Complications.Results A tota l of 3902 patients underwent surgery,of whom 73(1.87%)underwent unplanned reoperation.The main cause of unplanned reoperation was bleeding(50%).The disease types with the highest unplanned reoperation composition ratio were coronary heart disease(38.4%),and the disease types with the highest incidence were dilated cardiomyopathy(11.1%).The average hospitalization cost,the average length of hospitalization,mortality rate and medical dispute rate of patients who had unplanned reoperation were significantly higher than those who did not have unplanned reoperation,the difference was statistically significant(P=0.001).Conclusion The hospital should strengthen the perioperative management of cardiac surgery,focus on supervising disease types and surgical modalities with high incidence of unplanned reoperation,and strictly implement the system of operation classification and the system of reporting unplanned reoperation to ensure the quality of patient surgery.

With the rapid acceleration of aging in China, there is a huge need for elderly patients to have improved quality of life in the terminal stage.Palliative sedation is an integral part of palliative care and can alleviate painful refractory symptoms, and its use in patients in various terminal illnesses is being explored across the world.Attention is focused on its indications and implementation.In China, palliative sedation in clinical practice is in an early exploratory stage and relevant criteria and guidelines have yet to be established.A review of the current practice and research progress concerning palliative sedation for patients' end-of-life care in China and the rest of the world will offer insight and strategic considerations in the initial pursuit and accelerated acceptance in the future in China.

Objective:To evaluate the role of O-sialoglycoprotein endopeptidase (OSGEP) in hepatic ischemia-reperfusion injury (HIRI) and the relationship with oxidative stress in mice.Methods:Experiment Ⅰ Twenty-four SPF healthy male C57BL/6 mice, 12 wild-type and 12 OSGEP knockdown, aged 6-8 weeks, weighing 18-22 g, were divided into 4 groups ( n=6 each) by the random number table method: wild-type shamoperation group (Sham group), wild-type HIRI group (HIRI group), OSGEP knockdown+ sham operation group (Sham+ KD group) and OSGEP knockdown+ HIRI group (HIRI+ KD group). Ischemia-reperfusion model was prepared by blocking the hepatic artery and portal vein for 60 min followed by reperfusion in anesthetized animals, the blood vessels were only exposed without occlusion in Sham group and Sham+ KD group, and the blood vessels were clamped for 60 min followed by reperfusion in HIRI group and HIRI+ KD group. The mice were sacrificed after 6-h reperfusion to extract liver tissue samples for microscopic examination of histopathological changes (with an optical microscope after HE staining) which were evaluated using Suzuki score and for determination of the serum concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), level of reactive oxygen species (ROS) (using the DCFH-DA fluorescent probe method), contents of malondialdehyde (MDA) and glutathione(GSH) in liver tissues (using a colorimetric method) and expression of OSGEP (using Western blot). Experiment Ⅱ The well-growing AML12 cells were divided into 4 groups ( n=30 each) using a random number table method: control group (C group), oxygen-glucose deprivation/restoration (OGD/R) group, OGD/R+ OSGEP knockdown group (OGD/R+ KD group), and OGD/R+ OSGEP knockdown negative control group (OGD/R+ NC group). Group C was cultured under normal conditions. Group OGD/R was subjected to O 2-glucose deprivation for 6 h followed by restoration of O 2-glucose supply for 24 h in OGD/R group. In OGD/R+ KD group, stable transfection of AML12 cells with OSGEP knockdown was performed prior to the experiment, and the other procedures were the same as those previously described. The cell survival rate was measured by the CCK-8 assay, the release of lactate dehydrogenase (LDH) was measured, the DCFH-DA method was used to detect the levels of ROS, and the contents of MDA and GSH were determined using a colorimetric method. Results:Experiment Ⅰ Compared with Sham group, the expression of OSGEP was significantly down-regulated, the serum concentrations of AST and ALT, Suzuki score, levels of ROS and content of MDA were increased, and the GSH content was decreased in HIRI group ( P<0.05), and no significant change was found in each parameter in Sham+ KD group ( P>0.05). Compared with HIRI group, the serum concentrations of AST and ALT, Suzuki score, levels of ROS and content of MDA were significantly increased, and the GSH content was decreased in HIRI+ KD group ( P<0.05). Experiment Ⅱ Compared with group C, the expression of OSGEP was significantly down-regulated, the cell survival rate and GSH content were decreased, and the release of LDH, levels of ROS and content of MDA were increased in group OGD/R ( P<0.05). Compared with OGD/R group, the cell survival rate and GSH content were significantly decreased, and the release of LDH, levels of ROS and content of MDA were increased in OGD/R+ KD group ( P<0.05), and no significant change was found in each parameter in OGD/R+ NC group ( P>0.05). Conclusions:OSGEP plays an endogenous protective role in HIRI by inhibiting oxidative stress in mice.

【Objective】 To analyze the contributing factors of attention deficit hyperactivity disorder (ADHD) in children and the correlation between bone mineral density and physical growth, in order to provide new clues for the prevention and early intervention of ADHD. 【Methods】 A total of 116 children with ADHD were included into the observation group from June 2020 to June 2022, while another 80 healthy children in the same period were included as the control group.Clinical data of the two groups were compared, and the factors influencing ADHD in children were analyzed using multivariate Logistic regression. Children with ADHD were further divided into boys group and girls group based on gender. Bone mineral density (BMD) and physical growth (height and body weight) of the two groups were measured, and the correlation between the two was analyzed. 【Results】 In the observation group, the proportion of boys, maternal bad behaviors during pregnancy, their educational level below high school, critical parenting, and parental stress index were significantly higher compared to the control group (χ²=14.430, 5.689, 5.630, 6.738, t=6.936, P<0.05). Additionally, family environment score was significantly lower than that in the control group (t=6.328, P<0.05). Logistic regression analysis revealed that factors including boys (OR=3.298, 95%CI: 1.759 - 6.184), maternal bad behaviors during pregnancy (OR=2.730, 95%CI: 1.169 - 6.375), maternal education level of senior high school or below (OR=2.032, 95%CI: 1.127 - 3.663), critical parenting (OR=2.349, 95%CI: 1.223 - 4.513), and parental stress index (OR=1.089, 95%CI: 1.055 - 1.124) were positively correlated with ADHD in children (P<0.05), while family environment score was negatively related to ADHD (OR=0.868, 95%CI: 0.820 - 0.919, P<0.05). There were no significant differences in BMD, height and body weight between boys and girls in ADHD group (P>0.05). Pearson correlation analysis indicated a positive correlation of BMD with height and body weight (r=0.409, 0.317, P<0.05). 【Conclusions】 The development of ADHD in children is associated with gender, maternal bad behavior during pregnancy, family parental style and so on. Bone mineral density is closely related to physical growth in children with ADHD, clinical interventions can be implemented to prevent or early intervene ADHD.

Objective To investigate the efficacy and safety of hybrid surgery for the recanalization of carotid artery occlusion after stenting.Methods Clinical data and results of 17 patients with occlusion after carotid artery stenting and treated with hybrid surgery from June 2016 to April 2023 at the Department of Neurosurgery Cerebral Blood Flow Reconstruction Center of Xuanwu Hospital,Capital Medical University were retrospectively analyzed.According to whether the recanalization was successful,17 patients were divided into the the successful recanalization group and the failed recanalization group.Successful recanalization was defined as achieving modified thrombolysis in cerebral infarction(mTICI)grade ≥2b and residual stenosis＜50％.Baseline data(age,sex,body mass index,smoking history,alcohol consumption history,hypertension history,diabetes history,hyperlipidemia history,coronary heart disease history),clinical data(National Institutes of Health Stroke Scale[NIHSS]score at admission,fasting blood glucose,low density lipoprotein,high density lipoprotein,total cholesterol,triglyceride,occlusion side and segment,combination with severe stenosis or occlusion of the contralateral carotid artery,opening of the anterior communicating artery,opening of the posterior communicating artery,compensation of the external and internal carotid artery,compensation of the pia artery,stump morphology,and time from imaging diagnosis of occlusion to recanalization)were documented and compared between groups.The recanalization of occlusive vessels and perioperative complications were recorded.Imaging and clinical follow-up were performed 3,6 months and≥1 year after surgery.Results Among the 17 patients,the ratio of successful recanalization was 13/17.One patient had re-occlusion after operation,which was re-opened after thrombolysis,but neck hematoma with dyspnea occurred,and recovered after emergency operation.There was no postoperative stroke or death.The incidence of perioperative complications was 1/17.Compared with the successful recanalization group,the levels of high density lipoprotein and total cholesterol in the failed recanalization group were higher,and the differences between the groups were statistically significant(high density lipoprotein[1.3±0.3]mmol/L vs.[0.9±0.3]mmol/L,t=-2.139;total cholesterol:[4.2±0.8]mmol/L vs.[3.1±0.7]mmol/L,t=-2.649;both P＜0.05);There were no significant differences in other baseline data and clinical data(all P＞0.05).Imaging follow-up was completed in 9 of the 13 patients in the successful recanalization group,and the follow-up time was 3.8-36.9 months,with a median follow-up time of 22.8(12.8,34.7)months.Among them,1 patient(1/9)developed restenosis of recanalization vessels at 33.0 months after surgery and underwent stent implantation again.Conclusions The preliminary analysis showed that the occlusion after carotid artery stenting had better recanalization success and lower perioperative complications.In patients with chronic occlusion after carotid stenting,the application of a hybrid surgery for opening may be attempted under multimodal imaging assessment.

Objective To construct the triple pre-rehabilitation program for the patients undergoing pancreaticoduodenectomy to provide a theoretical basis for the preoperative management of this operation mode.Methods The raft plan was formed by the literature research and group discussion,then the experts were invited to conduct the two rounds of expert consultation,and the final draft of the plan was finally formed.Results The draft plan included the 3 first-level items,9 second-level items and 28 third-level items.The questionnaire recovery rate of the two rounds of expert correspondence was 100%,and the authority coef-ficients were 0.88 and 0.93,respectively.The mean importance and feasibility scores of each item in the two rounds of expert consultation were ≥3.5,and the coefficient of variation was<0.25.The first draft of the final formation plan included the 3 first-level items,9 second-level items and 31 third-level items.Conclusion This program has ne-cessity,scientificity and feasibility.Clarifying the specific contents and scope of preoperative management of this operation mode could provide a theoretical basis for medical staff to carry out pre-rehabilitation.

Objective To explore the etiology,types,treatment,and prognosis of new-onset epilep-sy in elderly dementia.Methods A retrospective analysis was conducted on 45 new-onset epilepsy in elderly dementia admitted to our department from January 2017 to December 2023.According to their etiology,they were divided into a degenerative dementia group(with AD as the main cause,AD dementia group,24 cases,)and a non-degenerative dementia group(non-AD dementia group,21 cases).Seizure types and and electroencephalogram(EEG)findings were compared be-tween the two groups.The medication and efficacy were also compared between the two groups in 3 months after treatment with antiepileptic drugs.Results Each patient had at least one type of seizure.The AD dementia group had a lower incidence of generalized seizure,but higher incidences of focal seizure and non-convulsive seizure(NCS)when compared with the non-AD dementia group(P＜0.05,P＜0.01).At least one type of abnormal EEG findings was observed in each pa-tient,but there was no statistical difference in the occurrence of EEG abnormalities between the two groups(P＞0.05).Among the 45 patients,42(93.3％)received antiepileptic drugs,and 38(90.5％)patients were well controlled,with the AD dementia group having a higher effective rate of single antiepileptic drug than the non-AD dementia group(95.5％vs 85.7％,P＜0.05).Conclu-sion Dementia combined with epilepsy(especially NCS)is often hard to detect,and continuous EEG monitoring is essential for elderly dementia patients.Most new-onset epilepsy in elderly de-mentia can be effectively controlled through antiepileptic drug therapy.

Pain is a prevalent symptom in both cancer and non-cancer end-stage diseases, often being the most feared by patients and significantly impacting their quality of life.Hospice care aims to address physical, psychological, spiritual, and other needs of patients and their families during this stage, with a focus on alleviating pain and discomfort.Effective pain management is a crucial component of hospice care, particularly given the increasing prevalence of cancer and chronic diseases in China and the growing elderly population.To provide analgesic management for hospice patients, a thorough assessment of pain is essential to identify its type and characteristics.Treatment approaches may include etiological interventions, pharmacotherapy, interventional therapy, physiotherapy, psychotherapy, and comfort care, all aimed at achieving comprehensive pain management.The use of opioid should be carefully guided by scientific principles to minimize adverse effects and optimize pain relief, ultimately enhancing patients' end-of-life quality of life.

Objective:To observe the occurrence of attention deficit hyperactivity disorder(ADHD) in children aged 3-12 and analyze the related factors of family environment leading to ADHD.Methods:A total of 580 children from June 2020 to December 2021 were selected from the pediatric outpatient clinic of the Children's Hospital of Kunming.According to the diagnostic criteria for children with ADHD in DSM-5, all the subjects were divided into ADHD group ( n=37) and non-ADHD group( n=543). The general data questionnaire and family assessment device (FAD) were used to investigate the relevant data of children.SPSS 25.0 software was used for statistical analysis, and t test, Mann-Whitney U test were used for inter group comparison, and binary Logistic regression model was used to analyze the related factors of family environment of ADHD in children aged 3-12 years. Results:Among 580 children aged 3-12 in pediatric clinic, 37 cases were diagnosed ADHD, accounting for 6.38%.Compared with the non-ADHD group, the breast-feeding time of children in the ADHD group was shorter, the education level of primary caregivers was lower(5.00(2.50, 6.00)months, 9.00(7.00, 11.00)months)( U=7.751), the proportions of families with single parent/reconstituted and parents with criticism and reprimand as the main educational method were higher, and the FAD score((172.35±4.27), (116.29±5.58), t=6.478) was higher (all P<0.05). The results of Logistic regression analysis showed that longer breast-feeding time ( β=-0.561, P<0.001, OR=0.571, 95% CI=0.480~0.678) was the protective factor of ADHD in children aged 3-12 years.Primary and junior high schools as the education level of main caregivers, criticism and reprimand as the main education methods of parents, and poor family function (high FA score) were the related risk factors of family environment of ADHD in children aged 3-12 years. Conclusion:Family environment factors, such as short breast-feeding time, low education level of main caregivers, criticism and reprimand of parents, poor family function, can increase the incidence risk of ADHD in children aged 3-12 years.

Objective:To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China.Methods:Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women′s socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis.Results:A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95% CI: 4.5%－6.1%) and 13.1% (95% CI: 11.3%－14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions:In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.
