Objective: To assess the efficacy and safety of combining traditional Chinese medicine (TCM), specifically Chinese herbal medicine (CHM), with Western medicine (WM), compared to WM alone to treat breast cancer endocrine therapy-related osteoporosis (BCET-OP) by meta-analysis. Methods: Thirty-eight randomized controlled trials involving 2170 participants were analyzed. Eight databases were searched for articles published between inception and December 2023. Quality assessment was performed using the Risk of Bias 2 tool. Results: Significant increases were observed in the TCM-WM group in lumbar vertebrae bone mineral density (BMD) (P < .001, mean difference (MD) = 0.07, 95% confidence interval (CI): 0.06 to 0.08), lumbar vertebrae T-score (P = .0005, MD = 0.21, 95%CI: 0.09 to 0.33) and collum femoris BMD (P = .01, MD = 0.10, 95%CI: 0.02 to 0.19). No significant difference was observed between the groups in the collum femoris T-score and estradiol levels. Bone gla-protein levels were significantly increased in the TCM-WM group (P = .0002, MD = 0.52, 95%CI: 0.25 to 0.79). Beta-CrossLaps decreased significantly in the TCM-WM group (P = .0008, MD = −0.10, 95%CI: −0.16 to −0.04). No significant difference was observed between the TCM-WM and WM groups in alkaline phosphatase, in procollagen type I N-terminal propeptide, and in the Kupperman index. The visual analog score (VAS) was decreased in the TCM-WM group compared to the WM group (P < .001, MD = −1.40, 95%CI: −1.94 to −0.87). No significant difference in adverse events was observed between the two groups. Conclusion Combining CHM with WM in patients with BCET-OP significantly improved BMD, T-score, and certain bone turnover markers and reduced the VAS score, indicating potential benefits for bone health and related pain. Adverse event analysis revealed no differences between the groups, supporting the feasibility of the combination therapy. However, further research, particularly in diverse populations, is required.

Objective:To investigate the correlation between serum lipoprotein (a) [LP(a)] and the severity of white matter hyperintensities (WMHs) in the middle-aged and elderly people in the community.Methods:Consecutive middle-aged and elderly residents residing in the community underwent physical examinations in the Affiliated Jiangning Hospital of Nanjing Medical University from June 2016 to August 2021 were retrospectively collected. Fasting venous blood was collected on the next day of admission to detect the level of Lp(a). During hospitalization, cranial MRI examination was performed and the severity of WMHs was graded using the Fazekas visual scoring method. Ordinal multivariate logistic regression analysis was used to determine independent related factors for the severity of WMHs.Results:A total of 1 752 patients were included in the analysis. There were 969 males (55.31%) and 783 females (44.69%). Their age was 66.18±10.32 years old. There were 1 167 patients (66.61%) in the mild WMHs group, 407 (23.23%) in the moderate WMHs group, and 178 (10.16%) in the severe WMHs group. Ordinal multivariable logistic regression analysis showed that after adjusting for confounding factors, a higher serum Lp(a) level was independently related to the severity of WMHs (with the first quartile as a reference, the third quartile: odds ratio 1.441, 95% confidence interval 1.050-1.976, P=0.023; the fourth quartile: odds ratio 1.717, 95% confidence interval 1.252-2.354, P=0.001). Conclusion:Serum Lp(a) is independently correlated with the severity of WMHs.

Objective:To explore the facilitating and inhibitory factors influencing the behavior of young patients to share medical electronic word-of-mouth (eWOM) on internet platforms, so as to provide insights for the improvement of healthcare quality.Methods:In May 2022, 271 undergraduate students from universities in Zhejiang province were selected by convenient sampling to survey their motivations to share eWOM with a self-designed questionnaire. Multiple regression analysis was used to examine the impact of different motivational factors on the sharing intention of young patients.Results:Only 16 respondents (5.9%) had previously published medical eWOM. Egoistic motivation, altruistic motivation, medical experience, and comment habits were significant factors that promoted patients to share eWOM, with egoistic motivation ( β=0.212, P<0.001) having the greatest impact and comment habit ( β=0.139, P=0.003) having the least impact. Distrust, low self-efficacy and involvement, perceived reluctance, and perceived uselessness were significant factors inhibiting patients from publishing eWOM. Of them, distrust ( β=-0.161, P<0.001) and perceived reluctance ( β=-0.161, P=0.001) had the greatest impact, and low self-efficacy and involvement had the least impact ( β=-0.134, P=0.003). Conclusions:To enhance the positive attitude of young patients towards sharing eWOM, it is important to focus on their personal benefits and provide high-quality healthcare experiences. Building trust among patients in the platform is crucial, and efforts should be made to reduce operational barriers. Additionally, educating and raising awareness among young patients regarding the significance and influence of healthcare reviews is important.

Objective:To explore the association of different obesity measurement indexes on serum C-reactive protein (CRP) in Chinese adult women.Methods:The data were obtained from baseline and follow-up surveys of the urban Breast Cancer Screening Program in Shuangliu District, Chengdu. A total of 441 adult women were included in the study. A questionnaire survey, physical examination, and laboratory testing were conducted on the subjects. Multivariate logistic regression model, two-level mixed effects logistic regression model, and restricted cubic spline method were used to investigate the linear and nonlinear correlation between different obesity measurement indexes and serum CRP in adult women.Results:For every 1 unit increase in BMI, waist circumference (WC), and adiposity, the risk of elevated serum CRP or exacerbation of chronic low-grade inflammation in adult women increased by 16.5%, 5.0%, and 11.1% ( P<0.05), respectively. Both BMI and adiposity were nonlinear correlated with serum CRP. Using BMI=24.0 kg/m 2 as the reference point, serum CRP level increased with the increase of BMI when BMI >24.0 kg/m 2. Using adiposity=30% as the reference point, serum CRP level increased with the increase of adiposity when adiposity >30%. Conclusions:Overall, obesity reflected by BMI had the strongest association with serum CRP in adult women, followed by body fat content reflected by adiposity, and central obesity reflected by WC had the weakest association with CRP. Adult women with BMI >24.0 kg/m 2 or adiposity >30% are at high risk for obesity-related inflammatory manifestations.

Hevin is one of the extracellular matrix proteins secreted by astrocytes. Under physiological conditions, Hevin plays an important role in synaptogenesis in the central nervous system (CNS); secreted protein, acidic and rich in cysteine (SPARC) is its homologue and antagonizes the synaptogenic effects of Hevin. In pathological conditions, the expressions of Hevin and SPARC are altered, suggesting their possible roles at synaptic reorganization in various disease process, such as brain injury, Alzheimer's disease, epilepsy and brain tumors; however, the specific mechanism is not totally understood yet. So this paper reviews the mechanism of Hevin/SPARC in CNS synaptogenesis, reorganization and diseases to provide ideas for further research.

Objective:To detective the cut-off values of amino acid levels in premature infants in Sichuan.Methods:Data of newborns screening for inherited metabolic diseases (IMD) by tandem mass spectrometry in Sichuan Province from January 2018 to December 2019 were retrospectively analyzed.They were divided into premature infant group ( n=2 264, 1 312 males and 952 females) and full-term infant group ( n=53 275, 28 269 males and 25 006 females). The cut-off values of amino acids in dry blood spots were expressed as percentage ( P0.5 - P99.5), and rank sum test was used for comparison between preterm and full-term infants.

Glioma is one of the most common primary intracranial tumors, accounting for 80% of malignant brain tumors. The conventional treatment of glioma is surgical resection followed by temozolomide chemotherapy, but the drug resistance will gradually appear that results in a poor prognosis of the patient. Berberine is an alkaloid extracted from Coptis Rhizoma, which has a wide range of pharmacological activities. It exerts its pharmacological effects on glioma such as inhibiting tumor growth through controlling different molecular and cellular pathways. In this article, the application of berberine in the treatment of glioma and the research progress of specific molecular mechanism are reviewed.
