Objective To evaluate the efficacy and safety of higenamine hydrochloride(HG) stress echocardiography for diagnosis of coronary artery disease (CAD). Methods The study was designed as prospective,randomized,open-labled,positively controlled and crossover phase II multi-center clinical research.Ninety subjects who were suspected to have CAD were enrolled.HG dosage was titrated at 0.5,1, 2,4 μg.kg -1.min-1every 3 min.Adenosine was injected 140 μg.kg -1.min-1for 6 min with total dosage 0.8 mg/kg.Visual assessment of the left ventricle wall motionand 17-segment model were used for analysis of stress echocardiography.CAD was defined as identifying >50% diameter stenosis in at least one major coronary artery by coronary angiogram.All adverse reaction were recorded. Results For HG group,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value were 28.9%,89.7%, 57.1%,76.5% and 47.8%,respectively;for adenosine group,they were 26.7%,94.9%,58.3%,85.7%and 47.1%,respectively. There was no significant difference between the two groups( P > 0.05). The diagnostic sensitivities of HG and adenosine echocardiography for single vessel stenosis were 11.1% and 5.6%,respectively( P >0.05).Both HG and adenosine echocardiography have the same sensitivity with 37.5% for double vessel stenosis and 44.4% for triple vessel stenosis.Advers reaction rate was 84.4% in HG group and 92.2% in adenosine group( P >0.05).Conclusions HG stress echocardiography for CAD diagnosis has high specificity,good safety and low sensitivity,which are similar to adenosine echo.

Objective:To explore the clinical effects of intramuscular injection of oryzanol for 5 and 10 days in the treatment of menopausal syndrome.Methods:This study adopts a case-control study method.Twenty patients with menopausal syndrome admitted to Peking Union Medical College Hospital from July 2021 to March 2022 were selected and randomly divided into a control group and an observation group using a random number table method, with 10 patients in each group. The control group was given intramuscular injection of oryzanol once a day for 5 consecutive days on the basis of routine health education; On the basis of routine health education, the observation group was given intramuscular injection of oryzanol once a day for 10 consecutive days. Two groups of patients completed a total of 6 visits before treatment and on days 5, 10, 30, 60, and 90 of treatment. Baseline survey was conducted to record the basic information of patients, including demography data, menstruation, past history, surgical history, drug allergy and the main symptoms of climacteric syndrome, and the baseline hormone level of patients was detected. Compare the menopausal symptoms by modified K-score, Pittsburgh sleep quality index (PSQI) score, menopausal specific quality of life (MENQOL) score, post treatment injection site pain by visual analog score (VAS), and observe adverse reactions during treatment between the two groups of patients at each visit time point.The measurement data conforming to the normal distribution is expressed in xˉ± s. The comparison between the two groups is performed by t test, and the change trend of the two groups at each time point is compared by repeated measurement analysis of variance; The measurement data that do not conform to the normal distribution are represented by M( Q1, Q3), and the Kruskal Wallis test is used for comparison between groups; Counting data is represented by examples(%), Fisher's exact probability method is used for inter group comparison, and Wilcoxon rank sum test is used for rank data comparison. Results:The body mass of the control group was higher than that of the observation group [(62.50±11.88) kg vs (52.90±4.28) kg, t=2.40, P=0.027]. There was no statistical difference between the two groups in other demography data and previous history, sex hormone levels, menopausal symptoms, and menstrual conditions (all P>0.05). Compared with the baseline, the modified K-score, PSQI score, and MENQOL vascular dilation and contraction, psychological state, physiological state, and sexual life scores of the two groups of patients on the 5th, 10th, 30th, 60th, and 90th day of treatment were significantly reduced, and showed a gradually decreasing trend with the extension of observation time (the values in Group F were 36.37, 12.40, 18.69, 24.73, 40.77, and 18.39, respectively, P<0.001), but there was no statistically significant difference between the groups (all P>0.05). After treatment, the VAS score of the control group was 1 point in 2 cases, 2 points in 4 cases, and 3 points in 4 cases; The VAS score of the observation group was 1 in 4 cases, 2 in 3 cases, and 3, 5, and 6 in 1 case each. There was no statistically significant difference in VAS scores between the two groups ( Z=0.43, P=0.664), and no adverse events or serious adverse events were observed during the treatment period. Conclusions:Intramuscular injection of oryzanol injection for 5 and 10 days can improve menopausal symptoms, improve sleep quality and overall quality of life in patients with menopausal syndrome, and the overall effect is similar.

Objective:To determine the effects of menopausal stage, age and other associated risk factors on symptoms of anxiety and depression among women in a community in Beijing.Methods:This study was a community-based prospective cohort. Participants who had transitioned through natural menopause, completed two or more depressive and anxiety symptoms evaluations, aged 35 to 64 years, and did not use hormone therapy were selected from the Peking Union Medical College Hospital aging longitudinal cohort of women in midlife to this analysis. The primary outcome variables were depressive and anxiety symptoms, assessed by hospital anxiety and depression scale (HADS). The generalized estimation equation was used in the statistical analysis.Results:Followed up from 2006 to 2014, 430 women and 2 533 HADS assessments were retained in the cohort. Depressive symptoms were more common than anxiety symptoms during all menopausal stages. The incidences of depressive and anxiety symptoms were 14.5% (19/191) and 3.1% (4/191) in the premenopausal -3 stage, respectively. The incidence increased in both menopausal transition and postmenopausal stage, with the highest incidence in the +1c stage [20.6% (155/751) and 8.8% (66/751), respectively]. However, these differences were not statistically significant (all P>0.05). Depressive symptoms were highest in the ≥60-<65 age group [20.8% (74/355)], and anxiety symptoms were highest in the ≥50-<55 age group [8.2% (62/754)]; but there were no statistical significances between different age groups and depressive and anxiety symptoms (all P>0.05). Multivariable analysis showed that high body mass index, low education status, and poor health status were independently associated with depressive symptoms (all P<0.05), and that poor health status, trouble falling asleep, and early awakening were independently associated with anxiety symptoms (all P<0.01). Conclusions:Depressive and anxiety symptoms are more common during menopausal transition and postmenopausal stage compared with reproductive stage. Depressive symptoms are more common than anxiety symptoms. To screen and assess depressive and anxiety symptoms in perimenopausal women is essential, especially for women with high risk factors.

Objective To establish macrosomia risk prediction models based on a cohort study, and to analyze and compare the results. Methods The research subjects were the pregnant women of the Chinese Pregnant Women Cohort Study. The general demographic information and clinical data of pregnant women were collected through the questionnaire and physical examination, and the related outcomes of newborns were obtained by follow-up. The dataset was divided into training set and test set by a 3:1 ratio. Multivariate logistic regression analysis (LR) and random forest algorithm (RF) were used to construct macrosomia risk prediction models in the training set, and the models were verified in the test set. The prediction efficiency of the models was evaluated by Kappa and the area under the receiver operating characteristic curve (ROC). Results Among 5544 pregnant women, 397 women delivered macrosomia, and the incidence of macrosomia was 7.16%. Among the pregnant women who delivered macrosomia, 10.08% (40/397) were over 35 years old, 27.46% (109/397) were overweight or obese, and 60.96% (242/397) were excessive gestational weight gain (GWG). LR was used to establish a macrosomia risk prediction model to predict the test set, with the accuracy of 0.716, the sensitivity of 0.719, the specificity of 0.715, the Kappa value of 0.428, the Yoden index of 0.393, and the AUC of 0.796 (95% CI: 0.777-0.815). RF was used to construct a risk prediction model to predict the test set, with the accuracy of 0.819, the sensitivity of 0.782, the specificity of 0.846, the Kappa value of 0.629, the Yoden index of 0.439, and the AUC of 0.897 (95% CI: 0.883-0.910). Conclusion The prediction effect of the two models is satisfactory. The random forest algorithm has a higher predictive effect on the risk of macrosomia in this cohort, but the multivariate logistic regression analysis can directly explain the influencing factors of the macrosomia. It is suggested to integrate the advantages of the two models in the future, so that they can play a more important role in macrosomia risk prediction.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.
