Objective: To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women. Methods: From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model. Results: A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome. Conclusion The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

Objective: To learn the status and influencing factors of development among infants at ages of 0 to 36 months in Xiaoshan District, Hangzhou City, so as to provide the reference for promoting healthy development of infants. Methods: Infants at ages of 0-36 months who underwent physical examination in Child Health Clinic of Xiaoshan District Community Health Service Center were selected in 2022. General data of infants and their mothers were collected through questionnaires, and the development status of infants was screened by Age and Stages Questionnaire (third edition). Factors affecting the development status were identified using a multivariable logistic regression model. Results: A total of 2 519 infants were investigated, including 1 339 males (53.16%) and 1 180 females (46.84%). There were 608 infants with abnormal development of at least one functional area of communication (CM), gross motor (GM), fine motor (FM), problems solving (CG) and personal-social (PS). The abnormal rate was 24.14%, and the abnormal rates of the above functional areas were 9.77%, 6.59%, 7.98%, 6.39% and 9.33%, respectively. Multivariable logistic regression analysis showed that gender (male, OR=1.563, 95%CI: 1.191-2.052), mother's childbearing age (≥35 years, OR=1.411, 95%CI: 1.001-1.988), mother's educational level (lower than junior college, OR=1.460, 95%CI: 1.116-1.912) were factors affecting abnormal development of CM; preterm birth (OR=2.323, 95%CI: 1.315-4.103) was factors affecting abnormal development of GM; gender (male, OR=1.654, 95%CI: 1.225-2.232) was factors affecting abnormal development of FM; gender (male, OR=1.511, 95%CI: 1.086-2.102) and mode of delivery (cesarean section, OR=1.460, 95%CI: 1.060-2.010) were factors affecting abnormal development of CG; gender (male, OR=1.340, 95%CI: 1.019-1.763) and birth weight (low birth weight, OR=1.985, 95%CI: 1.149-3.432) were factors affecting abnormal development of PS.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

ObjectiveTo investigate common dyadic coping (CDC) in linking with marital satisfaction and quality of life (QOL) in patients with brain injury and their spouses in a rehabilitation facility by using common fate model (CFM). MethodsFrom October, 2022 to June, 2023, 101 brain injury inpatients and their spouses in Beijing Bo'ai Hospital completed the questionnaire of Dyadic Coping Inventory, Kansas Marital Satisfaction Scale and World Health Organization Quality of Life. ResultsThe level of CDC between patients and their spouses significantly positively correlated with their marital satisfaction for both partners (β = 0.814, P < 0.001), as well as correlated with their quality of life (β = 0.271, P = 0.038; β = 0.481, P < 0.001). For the dimensions of QOL, the physical, psychological, social relationship and environmental dimensions significantly positive correlated with the CDC for the spouses, and only psychological and social relationship dimensions for the patients. ConclusionFacing the stress of brain injury, the level of CDC within couples can positively predict their marital satisfaction and QOL, and effect seems stronger for the spouses. It is advisable to consider both brain injured patients and their spouses as a whole to promote psychological adaptation and improve rehabilitation outcomes.

OBJECTIVE To analyze the medication reconciliation for the inpatients in cardiovascular medicine department ，to provide reference for the establishment of working mode of clinical pharmacists in the department of cardiovascular medicine and to provide a basis for clinical pharmacists and community pharmacists developing pharmaceutical care for patients after transfering to community health center. METHODS From October 2020 to September 2021，newly admitted or newly transferred inpatients with chronic disease were selected from Shiyan People ’s Hospital of Shenzhen Bao ’an District. Medication reconciliation was conducted by clinical pharmacists after pharmaceutical consultation. According to the Pharmaceutical Care Network Europe （PCNE） classification system V 9.1，the existing drug-related problems （DRPs）were classified and summarized. The effectiveness and safety evaluation，medication education and other measures were provided ，and the acceptance of intervention was analyzed at the same time. RESULTS A total of 100 patients were included ，including 54 males and 46 females. The average age was （60.21±9.69） years，the average number of chronic diseases was （2.84±0.83），and the median number of drugs was 5.00. Among them ，110 treatment drug deviations were found in 74 patients，involving 10 categories and 61 drugs. Top three drugs in the list of accumulative drug deviation were cardiovascular system drugs （35 deviations），digestive medicine drugs （16 deviations）and endocrine system drugs （15 deviations）. The above treatment drug deviation may cause 122 DRPs， mainly “treatment effectiveness”problems（74 DRPs），and the causes were “inappropriate medication time ormedication interval ”（32 DRPs）， followed by “inappropriate drug combination ”（10 DRPs）. Interventions to DRPs mainly concentrated on patient level ，drug level （58）and doctor level （58），155 of which （84.70％）were fully accepted and implemented. CONCLUSIONS Some patients have a weak awareness of medications according to doctor ’s advice；drug reconciliation led by clinical pharma- cists at admission can fully understand the potential drug problems of patients ，and help doctors improve the drug compliance of patients and ensure their medication safety .

Objective:To provide normal reference thresholds for clinical dynamic monitoring of the risk of microthrombus during pregnancy, we aimed to establish reference intervals of D-dimer in healthy pregnant women during different periods of gestation in Xi′an.Method:From December 2020 to March 2022, a total of 1502 healthy pregnant women and healthy non-pregnant women (healthy non-pregnant control group) who received routine prenatal examination in Northwest Women and Children′s Hospital were recruited in the study by questionnaire, including 1236 healthy pregnant women and 266 healthy non-pregnant control group. Plasma D-dimer concentration was detected by STA-R Evolution automatic blood coagulation analyzer and the concentration levels of D-dimer in different pregnancies and age groups were calculated using Graph Prism 9.0 software. In addition, 20 samples were collected in each pregnancy to verify the established reference interval.Results:There was no significant difference in plasma D-dimer levels between<30 years old and ≥30 years old at different gestational weeks. Plasma D-dimer level in healthy pregnant women group was significantly higher than that in healthy non-pregnant women group of the same age (P<0.05). With the increase of gestational week, plasma D-dimer level in pregnant women increased significantly, and plasma D-dimer level at different gestational weeks ≤13 weeks, 13+ 1-20 weeks, 20+ 1-27 weeks, 27+ 1-35 weeks, ≥35 +1 week were 0.33 (0.26, 0.47) μg/ml, 0.41 (0.30, 0.51) μg/ml, 0.71 (0.48, 0.94) μg/ml, 0.91 (0.70, 1.27) μg/ml, 1.30 (0.96, 1.72) μg/mlrespectively. Unilateral reference interval acuities were≤0.89 μg/ml, ≤1.53 μg/ml, ≤2.44 μg/ml, ≤2.74 μg/ml, ≤3.82 μg/ml respectively. The reference range established in this study was verified by 20 independent samples from each of the 5 gestational age groups, and the results were acceptable. Conclusion:This study preliminarily established the reference interval of plasma D-dimer in healthy pregnant women at different gestational weeks in Xi ′an area, which is helpful for the auxiliary diagnosis of thrombotic diseases during pregnancy.

Objective:To investigate the effect of pirfenidone (PFD) on the proliferation of human glomerular mesangial cells (HMC) stimulated by serum IgA1 in patients with IgA nephropathy (IgAN) and its possible mechanism.Methods:Serum IgA1 of IgAN patients was purified by Jacalin affinity chromatography combined with Sephacryl S-200 gel filtration, and then heated to aggregated form (aIgA1). CCK8 method was used to confirm the concentration and time of PFD. The cells were divided into blank control group, IgA1 (0.5 mg/ml) group and IgA1 (0.5 mg/ml)+PFD (2 mmol/L) group. The CCK8 method was used to detect proliferation of mesangial cells. The cell cycle was detected by flow cytometry, and the proliferation index of mesangial cells was calculated. The expression levels of transforming growth factor β1 (TGF-β1), Smad4, Smad7, fibronectin (FN) and collagen Ⅳ protein and mRNA were detected through Western blotting and real-time PCR.Results:Compared with blank control group, the proliferation of HMC was promoted significantly by aIgA1 ( P<0.05). After PFD treatment, the proliferation of HMC was significantly inhibited ( P<0.01). Compared with the blank control group, the number of G1 phase cells decreased, the number of S phase cells and cell proliferation index increased in IgA1 group (all P<0.05). Compared with IgA1 group, the number of cells in G1 phase increased significantly, the number of cells in S phase and G2/M phase decreased significantly, and the cell proliferation index decreased in IgA1+PFD group (all P<0.05). Western blotting and real-time PCR results showed that compared with the blank control group, the protein and mRNA expressions of collagen Ⅳ, FN and Smad4 in HMC stimulated by aIgA1 were significantly increased, while TGF-β1 protein expression was increased and Smad7 protein expression was decreased (all P<0.05). After PFD treatment, the protein and mRNA expression of collagen Ⅳ, FN and Smad4 in HMC was significantly decreased, while TGF-β1 protein expression was obviously decreased, and Smad7 protein was up-regulated (all P<0.05). There was no significant difference in the mRNA expression of TGF-β1 and Smad7 in each group before and after PFD treatment (all P>0.05). Conclusions:PFD can increase the arrest of HMC in G1 phase, inhibit the proliferation of HMC induced by aIgA1 of IgAN patients, and reduce the production of extracellular matrix. The mechanism may be related to up-regulation of Smad7 expression and down-regulation of TGF-β1/Smad4 pathway.
