OBJECTIVE To prepare an intelligent responsive liposome-hydrogel nanopreparation co-loaded with gambogic acid (GA), and characterize its antitumor activity in vitro . METHODS GA-ICG-Lip-gel was prepared by ethanol injection and cold dissolution, incorporating GA and the photosensitizer indocyanine green (ICG). The appearance and microscopic morphology of GA-ICG-Lip-gel were observed, its encapsulation efficiency and drug loading capacity were measured, and its photothermal conversion performance, photothermal stability, and infrared imaging properties were investigated, along with the determination of its in vitro release profile. Human breast cancer MCF-7 cells were used as objects to investigate the effects of GA-ICG-Lip-gel (or with near-infrared light irradiation) on cell viability, migration ability, and the cellular uptake capacity of GA-ICG-Lip-gel. RESULTS GA-ICG-Lip-gel existed in a solution state at room temperature and transformed into a gel state at 37 ℃. Its microstructure was dense with small pores, and its encapsulation efficiency and drug loading were (96.07±0.86) % and (6.28±1.16) %, respectively. After exposure to near-infrared light, the temperature of GA-ICG-Lip-gel rose above 42 ℃, with no significant attenuation observed in the heating curve. The heating efficiency was dependent on both the irradiation time and drug concentration. Compared to media without gelatinase, the cumulative release rate of GA-ICG-Lip-gel increased in media containing gelatinase. In vitro studies showed that GA-ICG-Lip-gel could be efficiently taken up by MCF-7 cells; GA-ICG-Lip-gel significantly inhibited the viability and migration ability of MCF-7 cells ( P <0.05), and this inhibitory effect was further enhanced under near-infrared light irradiation. CONCLUSIONS This study successfully prepares GA-ICG-Lip-gel, which exhibits favorable photothermal conversion properties and temperature/enzyme dual-responsive drug release characteristics, and demonstrates significant inhibitory effects on the proliferation and migration of breast cancer cells.

Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.

Patients with inflammatory bowel disease (IBD) require long-term pharmacotherapy. Due to the wide variety of clinically available drugs, medication safety has become increasingly concerning. As an indispensable component of pharmaceutical formulations, drug excipients may induce various adverse reactions, including rash, allergic responses, and gastrointestinal discomfort, and may even lead to severe organic injury. However, they are often overlooked in clinical practice. Therefore, identifying and managing excipient-related adverse reactions is crucial for ensuring medication safety. To address this issue, this article systematically reviews common excipients in IBD therapeutics, the underlying mechanisms of excipient-induced adverse reactions, and corresponding management strategies, aiming to enhance clinicians' awareness of excipient-related issues, improve their ability to recognize and manage such reactions, and ultimately ensure patient safety.

Background:
The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies.
Methods:
MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function.
Results:
Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores.
Conclusion
Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

Background:
Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients.
Methods:
Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines.
Results:
Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher.
Conclusion
MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

ObjectiveBy exploring the influencing factors of readmission in patients with stable angina of coronary heart disease (CHD) based on real-world clinical data, to establish a risk prediction model of integrated traditional Chinese and western medicine, in order to provide a basis for early identification of high-risk populations and reducing readmission rates. MethodsA prospective clinical study was conducted involving patients with stable angina pectoris of CHD, who were divided into a training set and a validation set at a 7∶3 ratio. General information, traditional Chinese medicine (TCM)-related data, and laboratory test results were uniformly collected. After a one-year follow-up, patients were classified into a readmission group and a non-readmission group based on whether they were readmitted. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for readmission. A risk prediction model of integrated traditional Chinese and western medicine was constructed and visualized using a nomogram. The model was validated and evaluated in terms of discrimination, calibration, and clinical decision curve analysis. ResultsA total of 682 patients were included, with 477 in the training set and 205 in the validation set, among whom 89 patients were readmitted. Multivariate logistic regression analysis identified heart failure history [OR = 6.93, 95% CI (1.58, 30.45)], wiry pulse [OR = 2.58, 95% CI (1.42, 4.72)], weak pulse [OR = 3.97, 95% CI (2.06, 7.67)], teeth-marked tongue [OR = 4.38, 95% CI (2.32, 8.27)], blood stasis constitution [OR = 2.17, 95% CI (1.06, 4.44)], phlegm-stasis mutual syndrome [OR = 3.64, 95% CI (1.87, 7.09)], and elevated non-high-density lipoprotein cholesterol [OR = 1.30, 95% CI (1.01, 1.69)] as influencing factors of readmission. These factors were used as predictors to construct a nomogram-based risk prediction model for readmission in patients with stable angina. The model demonstrated moderate predictive capability, with an area under the receiver operating characteristic curve (AUC) of 0.818 [95% CI (0.781, 0.852)] in the training set and 0.816 [95% CI (0.779, 0.850)] in the validation set. The Hosmer-Lemeshow test showed good calibration (χ² = 4.55, P = 0.80), and the model's predictive ability was stable. When the threshold probability exceeded 5%, the clinical net benefit of using the model to predict readmission risk was significantly higher than intervening in all patients. ConclusionHistory of heart failure, teeth-marked tongue, weak pulse, wiry pulse, phlegm-stasis mutual syndrome, blood stasis constitution, and non-high-density lipoprotein cholesterol are influencing factors for readmission in patients with stable angina of CHD. A clinical prediction model was developed based on these factors, which showed good discrimination, calibration, and clinical utility, providing a scientific basis for predicting readmission events in patients with stable angina.

Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

ObjectiveTo explore the clinical safety of Feilike Mixture (FLK) in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21,2021 and December 25,2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved,which are distributed across 12 provinces,including one traditional Chinese medicine (TCM) hospital and 28 general hospitals. The average age among the juveniles was (4.77±3.56) years old,and the average weight was (21.81±12.97) kg. Among them,119 cases (3.92%) of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles,with 1 656 cases (54.46%). FLK was first used in 2 016 cases (66.43%),and 142 juvenile patients had special dosages,accounting for 4.68%. Among them,92 adverse drug reactions (ADRs) occurred,including 73 cases of gastrointestinal system disorders,10 cases of metabolic and nutritional disorders,eight cases of skin and subcutaneous tissue diseases,two cases of vascular and lymphatic disorders,and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea,stool discoloration,and vomiting,and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages (the use of FLK)[odds ratio (OR) of 2.642, 95% confidence interval (CI) of 1.105-6.323],combined administration: spleen aminopeptide (OR of 4.978, 95%CI of 1.200-20.655),and reason for combined administration: anti-infection (OR of 1.814, 95%CI of 1.071-3.075) were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%,and the severity was mainly mild or moderate. Generally,the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction,suggesting that FLK has good clinical safety.

ObjectiveTo analyze the detected results of CD4+T lymphocytes and viral load in newly identified human immunodeficiency virus (HIV) infected patients in Huangpu District of Shanghai in 2023, to explore the correlation between them, so as to provide a scientific basis for the development of targeted prevention and control measures and antiviral treatment programs. MethodsThe data of CD4 cell count, viral load and demographic characteristics of the newly infected patients living with HIV in Huangpu District, Shanghai in 2023 were collected and analyzed by using descriptive epidemiological method. ResultsThe mean CD4 cell count of the 67 newly identified HIV infected patients in Huangpu District was (301.22±235.19) cells·µL-1, with a mean viral load of (5.15±1.28) ×105 copies·mL-1.There were statistically significant differences in CD4 cell count and viral load among different age groups (P<0.05), but there were no statistically significant differences by gender and marital status (both P>0.05). The CD4 cell count and CD4/CD8 ratio both were negatively correlated with the lg value of viral load (r=-0.290, -0.378; P=0.027, 0.002). ConclusionThe CD4 cell counts of the newly identified HIV infected patients in Huangpu District in 2023 were generally low, the proportion of patients with high viral load was high, but the risk for elderly infected with HIV was high. The elderly have gradually become the key population for AIDS prevention and control in Huangpu District. It is recommended to expand HIV screening in the elderly to reduce the risk of HIV transmission and increase the rate of early detection and treatment.
