ObjectiveTo investigate the efficacy and safety of Babaodan Capsule (BBD) in the treatment of patients with chronic hepatitis B virus (HBV) infection with damp-heat in the liver and gallbladder comorbid with gallbladder polyps. MethodsA randomized, double-blinded, placebo-controlled single-center trial was conducted among 120 patients with chronic HBV infection who were admitted to Beijing YouAn Hospital, Capital Medical University, from August 2020 to April 2023, and they were divided into treatment group (BBD) and control group (placebo), with 60 patients in each group. The course of treatment was 24 weeks, and follow-up assessments were conducted every 4 weeks. The primary outcome measures were the number and maximum diameter of gallbladder polyps (assessed by ultrasound), and the secondary outcome measures included traditional Chinese medicine (TCM) syndrome score, blood lipid levels, and liver function parameters. The independent-samples t test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups; the Wilcoxon rank-sum test was used for comparison of ranked data between two groups; the generalized estimating equation was used to analyze repeated measures data. ResultsAfter 8 weeks of treatment, the treatment group had a significantly smaller diameter of polyps and a significantly lower number of polyps than the control group (Z=-1.76 and -1.80, both P<0.05), and after 24 weeks of treatment, the treatment group had a significantly higher polyp reduction rate than the control group (30.51% vs 10.91%, P<0.05). The subgroup analysis showed that patients receiving combined antiviral therapy, male patients, patients with a diameter of polyps of <5 mm, and patients with multiple polyps tended to achieve significantly greater benefits. At week 8 of treatment, the treatment group had a significantly better TCM syndrome score than the control group (Z=-2.35, P<0.05); after treatment, compared with the control group, the treatment group had a significantly greater increase in high-density lipoprotein (Z=-1.85, P<0.05) and significantly lower levels of alanine aminotransferase (Z=-2.06, P <0.05), aspartate aminotransferase (Z=-2.13, P<0.05), total bilirubin (Z=-2.12, P<0.05), and direct bilirubin (Z=-3.09, P<0.05). No serious adverse events were reported in either group. ConclusionBBD can effectively reduce the size of gallbladder polyps, improve TCM syndrome score, and reduce the level of bilirubin in patients with chronic HBV infection with damp-heat in the liver and gallbladder, with a favorable safety profile, and it may be more suitable for patients receiving combined antiviral therapy and specific subgroups (male patients, patients with a diameter of polyps of <5 mm, and patients with multiple polyps.

OBJECTIVE To introduce the development of an intelligent prescription review decision-support system for anti-tumor drugs and assess its clinical application outcomes. METHODS Relevant data sources, including national and local pharmaceutical administration policies, clinical practice guidelines/consensus, hospital information systems data, and genetic testing results, were integrated. Adhering to the principles of structure, standardization and dynamic updating, a knowledge base covering chemotherapeutic, targeted and immunotherapeutic agents was constructed using a dual-dimensional modeling approach that combined “drug attributes” and “clinical contexts”. This knowledge base was then embedded into the hospital’s electronic medical order system to establish the prescription review decision-support system. The application and performance of the system were evaluated at Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. RESULTS A knowledge base containing 18 318 prescription review rules for anti-tumor drugs was constructed, and a closed-loop prescription review system was successfully established, encompassing pre-prescription real-time intervention, in-process interactive review, and post-prescription evaluation and analysis. From 2021 to 2024, the system generated a total of 57 879 alerts for prescriptions of five typical categories of anti-tumor drugs. For platinum-containing prescriptions, 22 577 alerts were generated, with Cisplatin for injection (lyophilized) being the most frequently alerted drug (13 445 alerts), and “ototoxicity risk due to combined use” alerts remained high (7 682 alerts). For methotrexate-containing prescriptions, 3 721 alerts were recorded, primarily related to “precaution-related issues” (76.4%, 2 843/3 721). For doxorubicin-containing prescriptions, 17 301 alerts were triggered, primarily related to “dosage and administration” (14 315 alerts). For human epidermal growth factor receptor 2-targeted agents-containing prescriptions, 1 007 alerts were issued, mostly related to “reimbursement restrictions” (956 alerts). For programmed death-1/programmed death-ligand 1 inhibitors-containing prescriptions, the alerts increased year by year, totaling 13 273 alerts, primarily related to “inappropriate indication” (9 118 alerts). Over the 4 years, the physician response rates to system alerts were 21.4%, 27.1%, 33.5% and 51.6%, respectively. CONCLUSIONS An intelligent decision-support system for anti-tumor drug prescription review, encompassing a closed-loop process of “real-time pre-event intervention, interactive in-event prescription review, post-event evaluation and analysis”, has been successfully constructed and implemented throughout the entire workflow. There is a discernible trend in this hospital, where the focus on monitoring anti-tumor drugs is shifting towards immunotherapy drugs. Additionally, the acceptance rate of physicians regarding prescription review opinions has been steadily increasing year by year.

ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis (CAG) with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching, patients were divided into a training set (namely dev) and a validation set (namely vad) in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator (namely Lasso) regression algorithms. Subsequently, a model, named model 1se, was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods, including the receiver operating characteristic (ROC) curve, Hosmer-Lemeshow test (H-L), calibration plot, and decision curve analysis (DCA). ResultsAge, body mass index (BMI), family history of cancer, job and life satisfaction, yellow and greasy fur with slippery pulse, and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration, which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).

Background Microparticles (MPs) are one of the main medium of inflammatory reaction with an important role in atherosclerotic progression. Studies on association of air pollution exposure and levels of peripheral blood MPs are limited among human. Objective To evaluate the effects of short-term exposure to air pollution on levels of peripheral blood MPs. Method A panel of 73 healthy adults was followed with 4 repeated follow-ups in Beijing, China, from November 2014 to January 2016. During each visit, we collected questionnaire information, fasting venous blood, urine, and exposures to fine particulate matter (PM2.5), black carbon, nitric oxide, nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon monoxide, and ozone. We used linear mixed-effect models to analyze associations of air pollution exposure with levels of total MPs (TMPs) and MPs derived from various cells. Stratified analysis was conducted by levels of C-reactive protein (CRP) and malondialdehyde (MDA). Results The results showed significant associations between air pollution exposure and peripheral blood TMPs at 2 h-6 d prior to the follow-ups (P<0.05), while no statistical associations were found for MPs derived from different cell types. Significant increases in TMPs of 7.8% (95%CI: 0.7%, 15.3%) and 14.3% (95%CI: 2.8%, 27.2%) were observed with each interquartile range (IQR) increase in PM2.5 (IQR=64.9 μg·m−3) at prior 18 h and NO (IQR=40.5 μg·m−3) at prior 48 h. Among participants with low levels of CRP and MDA, significantly positive associations were observed between air pollution exposure and levels of TMPs (P<0.05). Conclusion Short-term exposure to air pollution is significantly associated with increased levels of circulating MPs in healthy adults, and in people with lower systemic inflammation, peripheral blood MPs levels are more easily affected after exposure to air pollutants.

Objective:To understand the current status of medicinal plant consumption in Chinese elderly people; To explore associated influencing factors.Methods:Data were obtained from the 2018 cross-sectional survey of the Chinese Longitudinal Healthy Longevity Study (CLHLS) of (CLHLS-HF). Individuals aged 65 and above from 23 provinces (autonomous region, municipalities), who had completed the medicinal plant consumption response survey along with other parameters such as physical measurements, were selected as the study subjects. The χ2 analysis and multiple Logistic regression were used to analyse the medicinal plant consumption among the elderly and its influencing factors. Results:A total of 15 442 people were included. Among them, 9 750 were aged 80 and above, and 2 825 were aged 100 and above. 16.3% of Chinese elderly people reported occasional or frequent consumption of medicinal plants, with a higher proportion among males compared to females, urban residents compared to rural residents, and younger age groups compared to elderly groups ( P<0.001 or P<0.05). Among the 23 provinces (autonomous region, municipalities) surveyed nationwide, the proportion of elderly people who occasionally or frequently consume medicinal plants was over 25.0% in 10 regions. Guangdong, Shanghai, and Zhejiang ranked the top three, with percentages of 40.5% (380/939), 36.1% (229/634), and 28.6% (163/569), respectively. Multiple Logistic regression analysis revealed that factors influencing the level of medicinal plant consumption among the elderly included being a centenarian [ OR (95% CI)=1.361 (1.098,1.688), P=0.005], male [ OR (95% CI)=1.194 (1.051,1.358), P=0.005], Han nationality [ OR (95% CI)=1.374 (1.160,1.627), P=0.005], urban residence [ OR (95% CI)=1.917 (1.697,2.167), P=0.005], middle school education or higher education [ OR (95% CI)=2.061 (1.764,2.408), P<0.001], and elementary school [ OR (95% CI)=1.375 (1.183,1.598), P<0.001], current alcohol consumption [ OR (95% CI)=1.208 (1.029,1.418), P=0.021], current exercise [ OR (95% CI)=1.490 (1.325,1.675), P<0.001], regular fruit intake [ OR (95% CI)=1.213 (1.060,1.388), P=0.005], regular [ OR (95% CI)=4.149 (3.563,4.830), P<0.001] or occasional vitamin intake [ OR (95% CI)=5.593 (4.926,6.350), P<0.001], regular [ OR (95% CI)=2.296 (2.007, 2.628), P<0.001]or occasional tea consumption [ OR (95% CI)=3.030 (2.589, 3.545), P<0.001], and comorbidities (≥2) [ OR (95% CI)=1.343 (1.179,1.529), P<0.001], all positively correlated with occasional or frequent medicinal plant consumption among the elderly. Obesity [ OR (95% CI)=0.697 (0.548,0.888), P=0.003] and smoking [ OR (95% CI)=0.746 (0.627,0.887), P=0.001], on the other hand, showed a negative correlation with occasional or frequent medicinal plant consumption. Conclusion:The proportion of Chinese elderly people reporting occasional or frequent medicinal plant consumption is relatively high. However, it remains unclear whether this is based on the unique background of TCM culture or reflects the urgent demand for daily health maintenance among the elderly. Further efforts should be made to strengthen continuous observation, monitoring, and analysis of health outcomes in this population, exploring the potential benefits and risks.

Chinese Journal of Tissue Engineering Research 2025;29(1):156-163
BACKGROUND:Platelet-derived extracellular vesicles are the most abundant vesicles in the circulation,rich in bioactive molecules,genetic material,proteins and other information molecules,involved in cellular communication and material exchange,not only has good procoagulant activity,but also has the promotion of tissue repair and regeneration,and has a wide range of applications in regenerative medicine. OBJECTIVE:To elaborate the secretion mechanism of platelet-derived extracellular vesicles,their application in regenerative medicine,and limiting factors for clinical transformation,and to provide some theoretical support for the clinical translation of platelet-derived extracellular vesicles. METHODS:A computerized search of the PubMed database from January 2005 to August 2023 was applied to articles relating to platelet-derived extracellular vesicles with the search terms"platelet-derived,platelet-rich plasma,extracellular vesicles,isolated,microvesicles exosomes,applications".A total of 62 articles that met the subject criteria were finally included. RESULTS AND CONCLUSION:(1)Activated platelet-derived extracellular vesicles produce two types of vesicles,platelet-derived microparticles,whose secretion may be associated with the asymmetry of the actin cytoskeleton,and platelet-derived exosomes,which may be associated with the regulation of H+-ATPase.(2)Platelet-derived extracellular vesicles are potential effectors of platelet concentrates and platelets themselves,and may intervene in tissue regeneration by promoting angiogenesis,influencing cellular behavior,promoting coagulation and hemostasis,and exerting inflammatory effects.(3)Platelet-derived extracellular vesicles have been reported preclinically in the field of regenerative medicine such as tissue injury,muscle regeneration,cartilage regeneration,and osteoarthritis,and clinical trial data are available as potential therapeutic approaches for wound healing.However,factors such as isolation methods,sample sources,and the types of activators limit the clinical translation of platelet-derived extracellular vesicles into the field of regenerative medicine.(4)In the future,platelet-derived extracellular vesicles may become a cell-free alternative to platelet-rich plasma in regenerative medicine,but the clinical translation of platelet-derived extracellular vesicles needs to actively search for specific markers to differentiate platelet-derived microparticles from platelet-derived exosomes.The mechanism of activator-stimulated platelet-derived extracellular vesicle production,as well as the optimal method of platelet-derived extracellular vesicle collection,the optimal method of storage,the shelf life of the platelet-derived extracellular vesicles,the recommended dosage of platelet-derived extracellular vesicles for clinical application,and the optimal clinical indications need to be further investigated.

Objective :
To investigate the antidepressant effects and the underlying mechanisms of tetrahydrocurcumin(THC) and its nanoparticle formulation(THCN).
Methods :
Forty-six male ICR mice were randomly divided into Con group, LPS group, THC group, THCN group and SER group. A mouse depression model was established by intraperitoneal administration of LPS. The anxiety and depression-like behaviors of mice were evaluated by open field test(OFT) and forced swimming test(FST). Myelin staining was applied to assess the extent of demyelination in the prefrontal cortex of the mice. The prefrontal cortex and hippocampus were further examined for the expression levels of glial fibrillary acidic protein(GFAP) and Toll-like receptor 4(TLR4) through quantitative immunofluorescence assays.
Results :
Compared with the Con group, the LPS group showed increased anxiety-like and depressive-like behaviors in both the long-term and short-term experiments(P<0.05); the degree of demyelination increased in the LPS group of the long-term experiment(P<0.01); the expression of GFAP was reduced in the LPS group of the short-term experiment(P<0.01), while the expression of TLR4 increased(P<0.05); the expression of TLR4 decreased in the THC group(P<0.01); the expression of GFAP in the prefrontal cortex of the THCN group was reduced(P<0.01), while the expression of TLR4 increased(P<0.05). Compared with the LPS group, the THC group showed reduced depressive-like behaviors in the long-term experiment(P<0.05), while the anxiety-like and depressive-like behaviors of the THCN group and the SER group were reduced(P<0.05), and the anxiety-like and depressive-like behaviors of the THC group and the THCN group were reduced in the short-term experiment(P<0.05); the degree of demyelination was reduced in the THC group, THCN group and SER group in the long-term experiment(P<0.05); the expression of GFAP increased in the THC group of the short-term experiment(P<0.05), while the expression of TLR4 was reduced(P<0.05), and the expression of GFAP increased in the THCN group(P<0.05). Compared with the THC group, the THCN group and the SER group showed reduced anxiety-like behaviors in the long-term experiment(P<0.05); the expression of GFAP in the prefrontal cortex of the THCN group was reduced in the short-term experiment(P<0.05), while the expression of TLR4 in the hippocampal DG area increased in the short-term experiment(P<0.01).
Conclusion
Tetrahydrocurcumin and its nanoparticle formulation both exert significant ameliorative effects on depression-like behaviors and demyelination in mice induced by lipopolysaccharide. The antidepressant mechanism of THC appears to be mediated through the down-regulation of TLR4 and the up-regulation of GFAP. The mechanism underlying the antidepressant action of THCN seems predominantly focused on the enhancement of GFAP expression.
