Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

Objective:To investigate the impact of total cerebral small vessel disease (CSVD) burden on cognitive function in patients with minor ischemic stroke.Methods:Patients with first-ever acute minor ischemic stroke (AMIS) admitted to the Department of Neurology, Shenzhen Luohu District People's Hospital from January 2021 to December 2023 were included prospectively. According to the total CSVD burden score, they were divided into 0-2-point group, 3-point group, and 4-point group. According to the Clinical Dementia Rating (CDR) score at 6 months after onset, they were divided into a cognitively normal group and a post-stroke cognitive impairment (PSCI) group. The cognitive function assessment was conducted at 6 months after onset. The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were used to assess the overall cognitive function. The Auditory Verbal Learning Test-Huashan version (AVLT-H) was used to assess memory, the Trail Making Test (TMT) was used to assess executive function and attention, the Boston Naming Test (BNT) was used to assess language ability, and the Clock Drawing Test (CDT) was used to assess visual spatial function. Multivariate logistic regression analysis was used to determine the independent influencing factors of PSCI. Results:A total of 111 patients with AMIS were enrolled, including 53 males (47.7%), aged 69.18±7.41 years. 77 cases (69.4%) in 0-2-point group, 18 cases (16.2%) in 3-point group, and 16 cases (14.4%) in 4-point group; 39 cases (35.1%) experienced PSCI. Univariate analysis showed that age, and the proportion of patients with hypertension, diabetes, smoking, total CSVD burden score of 3 and 4 in the PSCI group was significantly higher than those in the cognitive normal group (all P<0.05), and the years of education was significantly lower than that in the cognitive normal group ( P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors (age, years of education, hypertension, diabetes, smoking), the total CSVD burden score 3 (compared with 0-2 points: odds ratio [ OR] 16.627, 95% confidence interval [ CI] 3.548-77.925; P<0.001) and 4 (compared to 0-2 points: OR 4.435, 95% CI 1.786-11.011; P=0.001) were the independent risk factors for PSCI. There were significant differences in MMSE, MoCA, AVLT-H, TMT-A, TMT-B, CDT, and CDR scores among different total CSVD burden score groups at 6 months after onset (all P<0.05). The overall cognitive function and functional scores of various cognitive domains gradually decreased with the increase of total CSVD burden score in patients with AMIS at 6 months after onset. Conclusions:In patients with AMIS with higher total CSVD burden at 6 months after onset, their overall cognitive function, memory, executive function, attention, and visual spatial function are decreased, and the incidence of PSCI is significantly increased.

Objective:To explore the correlation between abdominal aortic calcification and serum cell division cycle 42 (CDC-42) in maintenance hemodialysis (MHD) patients, and to explore the influencing factors of them.Methods:A cross-sectional study was conducted in the Blood Purification Center of Qingdao Municipal Hospital,112 patients who underwent MHD for more than 6 months from October 2019 to March 2021 were selected. The abdominal aortic calcification score (ACCs) was calculated by reference to the abdominal lateral X flat tablets. According to AACS, 50 cases were divided into no and mild calcification group (0≤AACS<5 points) and 62 cases were divided into moderate and severe calcification group (AACS≥5 points). The level of serum CDC-42 was detected by enzyme linked immunosorbent assay (ELISA). Taking the median serum CDC-42 level as the boundary, 56 cases were divided into low CDC-42 group and high CDC-42 group. Spearman correlation analysis was used to analyze the correlation between indicators. The risk factors of elevated CDC-42 and abdominal aortic calcification in MHD patients were explored by multivariate logistic regression analysis, and the variables were included by entry method.Results:In 112 patients, 91 cases (81.25%, 91/112) had abdominal aortic calcification, and the median serum CDC-42 level was 466.56 (335.56,623.57) ng/L. CDC-42, AACs, age, dialysis age, diabetic nephropathy, glycosylated hemoglobin, alkaline phosphatase, parathormone and calcium in the no and mild calcification groups were 347.77 (291.20, 419.53) ng/L, 1.00 (0.00, 3.00) points, (57.18±6.25) years, 31.50 (15.00, 49.25) months, 34.00%(17/50), (6.63±0.97)%, 116.22 (87.32, 152.13) U/L, 258.57 (143.40, 433.31) ng/L, (2.18±0.26) mmol/L, and in the moderate to severe calcification group were 602.69 (489.61, 762.73) ng/L, 10.00 (7.00, 16.25) points, (60.81±7.12) years, 49.00 (18.00, 67.00) months, 53.23%(33/62), (7.07±1.20)%, 144.34 (99.71, 201.76) U/L, 336.57 (230.63, 506.00) ng/L,(2.28±0.26) mmol/L, with statistically significant differences between the two groups(The statistical values were 6.99, 9.11, 2.83, 2.45, 4.14, 2.08, 2.04, 2.16 and 1.99, respectively, all P<0.05). CDC-42, AACs, glycosylated hemoglobin and parathormone in the low CDC-42 group were 336.50 (295.10, 395.25) ng/L, 2.00 (0.00, 4.00) points, (6.62±1.06) %, 250.60 (140.20, 462.02) ng/L,and in the high CDC-42 group were 622.92 (558.11, 836.65) ng/L, 10.00 (6.25, 15.75) points, (7.13±1.13) %, 347.21 (240.40,501.20) ng/L, with statistically significant differences between the two groups (The statistical values are 6.51, 5.21, 2.43 and 2.54, respectively,all P<0.05). Abdominal aortic calcification has positive correlations with CDC-42 ( r s=0.704, P<0.001), age ( r s=0.308, P=0.001), dialysis years ( r s=0.198, P=0.036), glycosylated hemoglobin ( r s=0.358, P<0.001), alkaline phosphatase ( r s=0.187, P=0.048), parathormone ( r s=0.437, P<0.001), serum calciu m( r s=0.323, P=0.001) and serum phospho-rus ( r s=0.251, P=0.007), and negative correlation with serum albumin( r s=-0.276, P=0.003). This study has confirmed that high serum CDC-42 ( OR=1.010, 95%CI:1.004-1.016, P=0.001) and senior dialysis age ( OR=1.033, 95%CI:1.006-1.061, P=0.018) were independent risk factors for moderate to severe abdominal aortic calcification.Serum CDC-42 levels has positive correlation with AACs ( r s=0.704, P<0.001), age ( r s=0.240, P=0.011), dialysis age ( r s=0.191, P=0.044), glycosylated hemoglobin ( r s=0.350, P<0.001), parathormone ( r s=0.380, P<0.001) and serum calcium ( r s=0.235, P=0.013). This study learned that,high AACs ( OR=1.185, 95%CI:1.037-1.354, P=0.013) and high parathormone ( OR=1.005, 95%CI:1.001-1.009, P=0.009) were independent risk factors for high CDC-42. The area under the receiver operating characteristic curve (ROC-AUC) of serum CDC-42 in predicting moderate and severe abdominal aortic calcification in MHD patients was 0.885. When the cut-off point was 466.56 ng/L, the predictive sensitivity and specificity were 79% and 86% respectively. Conclusion:The degree of abdominal aortic calcification in MHD patients was positively correlated with the level of serum CDC-42. High serum CDC-42 and high dialysis age were independent risk factors for abdominal aortic calcification in MHD patients. High AACS and high parathyroid hormone were independent risk factors for the increase of serum CDC-42 in MHD patients .

Post-stroke cognitive impairment (PSCI) refers to the decline of cognitive function after stroke, including mild cognitive impairment and dementia. It is very important to prevent PSCI, and it is a direction worth exploring to find the predictors. This article reviews the research progress of the predictors of PSCI, including demographic characteristics, imaging characteristics of stroke onset, stroke itself characteristics, and molecular markers, hoping to help screen high-risk patients and intervene in time to delay the occurrence and development of PSCI.

【Objective】 To develop an assay to determine β-lactam antibiotics using microcolumn gels and to study the β-lactam antibiotics present in the blood of patients and their clinical significances. 【Methods】 446 patients with a history of taking β-lactam antibiotics from January 2019 to June 2019 were randomly selected from Trauma Emergency Center, Department of Arthrosis, Department of Spine and Department of Bone Oncology of our hospital, and 4 mL(per capita) venous blood was collected. Irregular antibody screening, anti-globulin detection and drug antibody determination were performed by microcolumn gel method. The data of gender, age, disease, blood transfusion history and medication were collected. The test results and clinical data were retrospective analyzed. 【Results】 The yielding rate of antibody was 0.45%(2/446) in patients with a history of taking β -lactam antibiotics. 16.38%(73/446) of the samples were positive in direct antiglobulin test, and 64.38%(47/73) of them did not agglutinate with RBCs treated with drugs. The yielding rate of specific antibodies against drug was 4.93%(22/446), and the titer ranged from 2 to 128(8). 1 case of auto-IgM antibody, 1 case of blood group related antibody and 2 cases of non-specific protein adsorption were detected. The yielding rate of drug antibody in patients with blood transfusion history reached to 12.10 %(22/124), so it was also high in patients with bone tumor. 【Conclusion】 Direct antiglobulin assay is helpful for the detection of β-lactam antibodies. The negative results of antibody screening cannot completely exclude the presence of drug antibodies. The yielding rate of drug antibody can be greatly improved by specific drug antibody detection, and it was higher in transfused patients relative to non-transfused one.
