Objective To discuss the nursing characteristics in patients with heart failure of alcoholic cardiomyopathy during hospitalization.Methods 16 patients with heart failure of alcoholic cardiomyopathy were studied and experience summarizations were made from four different aspects:normal nursing,life sign monitoring,observation and nursing during medication and psychological nursing.Results After abstinence of alcohol,heart failure treatment,nutrition treatment of cardiac muscle,detailed observation and careful nursing,the heart function of the 16 patients were improved,and the symptom disappeared so that those patients were ready to leave the hospital.Conclusion The key for the treatment in heart failure of alcoholic cardiomyopathy is immediate and thorough abstinence of alcohol,and,if heart failure happens,life sign monitoring,medication observation and psychological nursing are also important.

Objective To understand the occurrence and the related risk factors of birth defects. Methods Descriptive analysis was conducted on birth detect surveillance in the infants during January 2008 to June 2014. Results A total of 777 cases of birth defect were detected in 73498 infants, and the incidence of birth defect was 1.06%. The 5 most common birth de-fects were congenital heart disease, multi ifnger (toe), hypospadias, cleft lip, and palate and deformity of external ear. Compared infants born with no birth defects, male, preterm, low birth weight, twin and multiple births and resident were statistically higher in infants with birth defects (P<0.05). The major risk factors of birth defects were the medication history, spontaneous abortion, gestational diabetes mellitus, and family history. Conclusions The incidence of birth defect can be reduced by providing good health care during pre-marriage and pregnant so as to decrease the occurrence of premature infants, twins and multiple births, and low birth weight as well as improving prenatal diagnosis and intensifying birth defects surveillance.

BACKGROUND:With the deepening of bone tissue engineering research and bone metabolism understanding, it is a hotspot to analyze the blood supply and nutritional status of tissue-engineered bone.
OBJECTIVE:To compare different methods for evaluating smal vascular network distribution around the knee joint in rats in order to provide a guideline for the study of microvascular network in tissue-engineered bone.
METHODS:Eighteen Sprague-Dawley rats were randomly divided into three groups, with six rats in each group. Three commonly methods were used to evaluate the smal vascular network around the knee joint in rats:immunohistochemistry analysis, angiography analysis, and CT scans and reconstruction analysis.
RESULTS AND CONCLUSION:The microstructure of vascular network could be observed by immunohistochemistry, but the spatial distribution of vessels could not be evaluated. The spatial distribution of vessels could be showed by angiography and CT scans. However, some of micro vessels were showed unclearly by CT scans. The number of blood vessels detected by immunohistochemistry was (26.50±3.02) vessels, significantly higher than those detected by angiography and CT scans that were (14.12±1.47) and (9.00±1.79) vessels, respectively. Combination of immunohistochemistry and angiography can evaluate the microvascular network at microscopic and macroscopic levels, which can provide the whole information of the vascular network.

China prospective multicenter birth cohort (Prospective Omics Health Atlas birth cohort, POHA birth cohort) study was officially launched in 2022. This study, in collaboration with 12 participating units, aims to establish a high-quality, multidimensional cohort comprising 20 000 naturally conceived families and assisted reproductive families. The study involves long-term follow-up of parents and offspring, with corresponding biological samples collected at key time points. Through multi-omics testing and analysis, the study aims to conduct multi-omics big data research across the entire maternal and infant life cycle. The goal is to identify new biomarkers for maternal and infant diseases and provide scientific evidence for risk prediction related to maternal diseases and neonatal health.
