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.

Objective To evaluate the cost-utility of risdiplam in the treatment of pediatric spinal muscular atrophy (SMA) and analyze changes in patients’ out-of-pocket economic burden under the medical insurance scenarios. Methods A Markov model was developed from the healthcare system perspective to compare the long-term costs and quality-adjusted life years (QALYs) of risdiplam treatment versus conventional therapy. The incremental cost-utility ratio (ICUR) was calculated. One-way sensitivity analysis and probabilistic sensitivity analysis were conducted to assess the robustness of the model. On this basis, health insurance scenarios were simulated to evaluate patients’ individual economic burden. Results Base-case analysis showed that risdiplam treatment generated additional health benefits but substantially increased medical costs. The resulting ICUR did not demonstrate a clear cost-utility advantage under the current willingness-to-pay threshold. Sensitivity analyses indicated that the model results were relatively robust, with drug costs and key utility parameters being the main drivers of economic outcomes. Health insurance scenario analysis demonstrated that increasing reimbursement levels and reducing patient copayment rates could significantly alleviate patients’ financial burden. Conclusion Risdiplam for pediatric SMA faces economic challenges under the current health insurance payment framework in China. However, optimizing health insurance reimbursement policies and developing multi-tiered healthcare security mechanisms may improve its affordability and accessibility.
5.Epidemiological characteristics of influenza-like illness and detection of influenza viruses in Xiaogan City, Hubei Province, 2020‒2024
Shanghai Journal of Preventive Medicine 2026;38(7):522-526
ObjectiveTo analyze the epidemiological characteristics of influenza-like illness (ILI) cases and the distribution patterns of influenza virus types in Xiaogan City from 2020 to 2024, and to provide a scientific basis for local influenza prevention and control. MethodsData on ILI surveillance reported by two national sentinel hospitals in Xiaogan City and influenza virus detection data reported by the network laboratory of Xiaogan Center for Disease Control and Prevention during 2020‒2024 were collected. All data were stratified and statistically analyzed by time, age and gender. Inter-group differences were compared using the chi-square (χ²) test, and statistical analyses were performed with SPSS 27.0 software. ResultsA total of 781 528 outpatient and emergency cases were reported by two sentinel hospitals in Xiaogan City from 2020 to 2024, among which 34 078 were ILI cases, with an ILI proportion (ILI%) of 4.36%. The highest proportion of ILI cases was observed in the 0‒<5 years age group, accounting for 28.62% (9 754/34 078). A total of 11 000 surveillance samples were tested, and 1 515 were positive for influenza virus, with an overall positive rate of 13.77%. Among the positive samples, 724 (47.79%) were influenza A (H3N2) subtype, 232 (15.31%) were influenza A (H1N1) subtype, 554 (36.57%) were influenza B (Victoria lineage), and 5 (0.33%) were mixed infections. A statistically significant difference was found in the seasonal distribution of influenza virus positivity rate (χ²=9 120.63, P<0.001). Epidemic peaks mainly occurred in winter and spring, with positivity rates ranging from 42.22% to 76.62%, while summer epidemic peaks were observed only in 2021 and 2022 (positivity rate was 21.48% and 43.03%, respectively). A statistically significant difference was also observed in influenza virus positivity rate among different age groups (χ²=846.61, P<0.001), with the highest influenza positive rate in the 5‒<15 years age group. No statistically significant difference was found in gender distribution (χ²=2.43, P=0.650). ConclusionThe influenza epidemic season in Xiaogan City is mainly in winter and spring, with occasional summer peaks. Prevention and control efforts should focus on children and adolescents aged 5 to <15 years, and targeted measures should be adopted in key settings such as schools. It is necessary to continuously strengthen influenza surveillance to provide a scientific basis for formulating prevention and control strategies.

ObjectiveTo investigate the impact of hepatocellular carcinoma (HCC) on the prognosis of patients with liver cirrhosis undergoing emergency endoscopic therapy for esophagogastric variceal bleeding, as well as independent influencing factors for the prognosis of liver cirrhosis patients without HCC after emergency endoscopic therapy for esophagogastric variceal bleeding. MethodsA total of 117 liver cirrhosis patients without HCC and 119 liver cirrhosis patients with HCC who underwent emergency endoscopic therapy for esophagogastric variceal bleeding in Renmin Hospital of Wuhan University from January 2017 to July 2023 were enrolled. Basic information including age and sex was collected from all patients, as well as the presence or absence of chronic diseases such as hypertension, diabetes, and coronary heart disease, the time of emergency endoscopy after admission, and liver function parameters including international normalized ratio, albumin, creatinine, sodium, total bilirubin, alanine aminotransferase, and aspartate aminotransferase (AST). The independent-samples t test was used for comparison of normally distributed continuous variables between two groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous variables between two groups; the chi-square test was used for comparison of categorical variables between groups. The covariance analysis and the multivariate logistic regression analysis were used for comparison of outcome variables after control of baseline variables, and the Kaplan-Meier survival curve was plotted for each group. The univariate and multivariate Cox regression analyses were performed for survival time in the non-HCC group to investigate the independent influencing factors for survival time, and then the Kaplan-Meier curve analysis and the log-rank test were performed to validate such independent influencing factors and analyze the independent influencing factors for secondary outcomes. ResultsCompared with the non-HCC group, the HCC group had significantly higher red blood cell transfusion units (6.00[2.00~9.00] vs 4.00[1.75~7.00], Z=-2.050, P=0.040, F=4.869, adjusted P=0.028), a significantly shorter survival time (29.77±16.01 days vs 38.07±11.43 days, t=4.574, P<0.001, F=17.294, adjusted P<0.001), and a significantly higher 5-day rebleeding rate (22.69% vs 6.84%, χ2=11.736, P<0.001, adjusted P=0.021). The Kaplan-Meier curve analysis showed that the risk of 42-day mortality in the HCC group was 3.897 (95% confidence interval [CI]: 2.338 — 6.495, P<0.001) times that in the non-HCC group. The multivariate Cox regression analysis of the non-HCC group showed that the total length of hospital stay (hazard ratio [HR]=0.793, 95%CI: 0.644 — 0.976, P=0.029) was an independent protective factor for 42-day survival. The Kaplan-Meier curve analysis showed that a length of hospital stay of >9 days was beneficial for the prognosis of patients (HR=4.302, 95%CI: 1.439 — 12.870, P=0.037). Blood sodium level (odds ratio [OR]=0.523, 95%CI: 0.289 — 0.945, P=0.032) and MELD-Na score (OR=0.495, 95%CI: 0.257 — 0.954, P=0.036) were independent protective factors against 5-day rebleeding, while AST level was an independent risk factor for 5-day rebleeding (OR=1.023, 95%CI: 1.002 — 1.043, P=0.028) and in-hospital death (OR=1.036, 95%CI: 1.001— 1.073, P=0.045). ConclusionLiver cirrhosis patients with variceal bleeding and HCC tend to have a worse prognosis, and for the non-HCC group, in-hospital mortality rate increases with the increase in AST level. The total length of hospital stay is an independent protective factor for survival time in the non-HCC group, and it is recommended to appropriately prolong the length of hospital stay for such patients.

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.

To evaluate long-term survival and clinical outcomes of patients with knee osteo-arthritis undergoing total knee arthroplasty (TKA) through long-term follow-up. This study was based on a previous cohort study that had completed follow-up. We retrospectively collected clinical data of patients with knee arthropathy (including knee osteoarthritis and knee rheumatoid arthritis) who received the first TKA operation in Peking Union Medical College Hospital from 1993 to 2002 and were followed up for more than 20 years, and conducted a unified follow-up on them in November 10, 2024 (the last follow-up). Kaplan-Meier curve was used to evaluate the survival rate. Hospitals for special surgery (HSS) scores and joint range of motion (ROM) were compared before surgery, 10 years after surgery and at the last follow-up to evaluate the clinical efficacy of TKA. Likert scale was used to evaluate patient satisfaction at the last follow-up. A total of 226 patients (246 knees) received their first TKA in Peking Union Medical College Hospital from 1993 to 2002 and were followed up for more than 10 years. Among them, 104 patients (131 knees) were included in the study at the last follow-up, including 21 patients (24 knees) with prosthesis in place, 18 patients (18 knees) who underwent reoperation for various reasons, and 65 patients (89 knees) who died from non-TKA surgical causes. Up to the last follow-up, there were 29 patients (35 knees) with an average follow-up of more than 20 years, and 12 patients (16 knees) completed HSS score, ROM measurement and patient satisfaction evaluation. Kaplan-Meier curve showed that the 10-year, 15-year, 20-year, and 25-year survival rates were 93.6%, 92.4%, 89.8%, and 71.8%, respectively. The HSS score at the last follow-up was lower than that at 10- year postoperative follow-up[(84.69±11.03) scores TKA treatment for knee arthropathy has high long-term prosthesis survival rate, significant improvement of knee joint function and high patient satisfaction.

To analyze the occurrence of early complications after total hip arthroplasty (THA) in patients with systemic lupus erythematosus (SLE). The data of patients who underwent THA at Peking Union Medical College Hospital from June 2012 to April 2024 were retrospectively and consecutively collected. The patients were categorized into SLE group and control group based on the presence or absence of SLE. Using propensity score matching, we matched patients in the two groups at a 1∶1 ratio according to gender, age, and surgical side. Subsequently, we compared the clinical characteristics, incidence of major complications within 30 days postoperatively, and allogeneic blood transfusion rates between the two groups. A total of 270 patients in the SLE group who met the inclusion and exclusion criteria were selected. Within 30 days postoperatively, 18 cases (6.67%) experienced major complications, including 2 cases (0.74%) of upper respiratory tract infection, 2 cases (0.74%) of pulmonary infection, 3 cases (1.11%) of urinary tract infection, 2 cases (0.74%) of other systemic infection, 5 cases (1.85%) of poor wound healing, 1 case (0.37%) of wound infection, 1 case (0.37%) of gastrointestinal complications, 1 cases (0.37%) of shock, and 1 case (0.37%) of SLE flare-up. The allogeneic blood transfusion rate was 22.59% (61/270). After propensity score matching, 163 cases from SLE and control groups were included for analysis. (1) Regarding medical complications, compared with control group, SLE group showed significant differences in osteoporosis, respiratory system disorders, gastrointestinal diseases, urinary system disorders, hematologic abnormalities, and secondary or concomitant rheumatic diseases (all The incidence of major complications within 30 days following THA in patients with SLE was significantly higher than that in non-SLE patients, while the rate of allogeneic blood transfusion remained comparable. To ensure the safety of THA surgery for patients with SLE, it is important to optimize the patient's condition and achieve stabilization prior to surgery. Additionally, strict perioperative management must be forced.
