ObjectiveTo investigate whether anti-programmed death-1 （PD-1） monoclonal antibody can enhance the efficacy and safety of argon-helium cryoablation combined with targeted therapy in patients with unresectable hepatocellular carcinoma （uHCC） aged 60 years or older. MethodsA retrospective analysis was performed for the clinical data of 124 patients with advanced uHCC aged 60 years or older who were treated at The Fifth Medical Center of Chinese PLA General Hospital from January 2013 to September 2024. After propensity score matching， 57 patients received cryoablation combined with targeted therapy （double combination group）， while 57 received cryoablation combined with targeted therapy and anti-PD-1 monoclonal antibody （triple combination group）. The indicators for efficacy assessment included objective response rate （ORR）， disease control rate （DCR）， progression-free survival （PFS）， overall survival （OS）， and the incidence rate of adverse events. The Mann-Whitney U 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 Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison between groups. A Cox proportional-hazards regression model analysis was used to investigate the influencing factors for survival prognosis. ResultsThe triple combination group had a significantly higher ORR than the double combination group （59.6% vs 29.8%， χ²=9.083， P=0.003）， while there was no significant difference in DCR between the two groups （87.7% vs 77.2%， χ²=1.516， P=0.218）， and compared with the double combination group， the triple combination group had significantly longer median PFS （9.1 months vs 4.8 months， χ²=7.813， P=0.005） and median OS （26.1 months vs 13.6 months， χ²=14.199， P<0.001）. The multivariate Cox proportional-hazards regression model analysis showed that triple combination treatment was an independent influencing factor for PFS （hazard ratio ［HR］=0.52， 95% confidence interval ［CI］： 0.35 — 0.78， P=0.001） and OS （HR=0.32， 95%CI： 0.20 — 0.51， P<0.001）. There was no significant difference in the incidence rate of adverse events between the two groups （P>0.05）. ConclusionTriple combination treatment with argon-helium cryoablation， targeted therapy， and anti-PD-1 monoclonal antibody can significantly improve survival benefits in uHCC patients aged 60 years or older， with a controllable safety profile.

Objective:To explore the potential profile characteristics of family health in patients with chronic diseases, analyze the influencing factors of different family health categories, and further investigate the relationship between family health categories and the quality of life in patients with chronic diseases, providing a scientific basis for targeted intervention strategies.Methods:This study was a cross-sectional survey. The data for the study were obtained from the Chinese Residents' Psychology and Behavior Survey Research Database. A multistage sampling method was employed to select 1 808 patients with chronic diseases as survey respondents from July to September 2021. Data were collected using the General Information Questionnaire, the Family Health Scale, and the European 5-Dimensional 5-Level Health Scale(EQ-5D-5L). Potential profiles of family health in patients with chronic diseases were identified using latent profile analysis. Univariate analysis and multiple Logistic regression were used to examine influencing factors, and generalized linear regression was performed to analyze the impact of different family health categories on quality of life.Results:A total of 1 808 chronic disease patients were enrolled, comprising 986 males and 822 females, with a age of (55.23 ± 7.02) years. The scores of family health, EQ-5D-5L, EuroQol Visual Analogue Scale were 38(34, 43), 0.94(0.84, 1.00), and 78(63, 87) points. The family health of patients with chronic diseases were categorized into three potential profiles: the low family health group (418 cases accounting for 23.1%), the medium family health group (747 cases accounting for 41.3%), and the high family health group (643 cases accounting for 35.6%). Multivariate Logistic regression analysis showed that family type, marital status, nature of household, education level, number of siblings and type of health insurance were significant factors influencing family health categories ( OR values were 0.464-2.503, all P<0.05). The family health was an important factor influencing quality of life ( χ2 values were 4.05-100.68, all P<0.05). Conclusions:There is significant heterogeneity in the family health of patients with chronic diseases, which can be divided into three distinct categories. Patients with higher family health levels have better quality of life. Medical professionals should develop precise intervention programs tailored to the characteristics of each category to improve family health levels and enhance the quality of life of patients with chronic diseases.

Objective:To address the critical issue of missing dynamic border molding information in edentulous direct digital impression technology, this study explores innovative digital solutions and conducts preliminary application validation.Methods:Based on the myostatic line theory, a methodology was established: intraoral scanner (IOS) high-frequency video was utilized to dynamically capture functional molding data of soft tissues, integrated with a self-developed mobility gradient recognition algorithm to achieve dynamic threshold segmentation between the muscle dynamic zone and myostatic zone, termed "optical digital molding technology". Ten edentulous patients with well-fitting complete dentures, treated at the Department of Prosthodontics, Peking University School and Hospital of Stomatology from January 2024 to December 2024, were enrolled. The standard deviation between the muscle static line (generated by mobility gradient algorithm with thresholds of 0.3-0.7 mm) and the denture border curve was analyzed to optimize the dynamic threshold, followed by single-case clinical validation.Results:Among the mobility thresholds of 0.3-0.7 mm, the 0.5 mm threshold yielded the smallest standard deviation between the myostatic line and denture border. Clinical validation demonstrated that dentures designed with this threshold exhibited no displacement during dynamic functional tests, with marginal sealing meeting clinical standards.Conclusions:The optical digital border molding technique for edentulous soft tissue boundaries translates the myostatic line theory into quantifiable parameters for the first time. Based on data from 10 cases, a mobility threshold of 0.5 mm is recommended for clinical application.

Objective:To compare the clinical efficacy and safety of nanomicroneedle- versus ultrasound-mediated delivery of tranexamic acid for the treatment of melasma.Methods:A prospective, randomized, controlled study was conducted. Patients with melasma were collected from the Department of Dermatology, Guangzhou Dermatology Hospital from March 2023 to May 2024, and divided into a nanomicroneedle group (receiving nanomicroneedle-mediated delivery of tranexamic acid) and an ultrasound group (receiving ultrasound-mediated delivery of tranexamic acid) using the random number table method. Both groups underwent the treatment once a week for a total of 8 sessions. At week 12, outcomes including melasma area and severity index (MASI) scores, treatment response rates, VISIA brown spot scores, pain scores, and adverse reactions were evaluated and compared between the two groups. Statistical analyses were carried out using two-independent-sample t test, Mann-Whitney U test, and chi-square test. Results:A total of 80 patients with melasma were included, with 40 in each group. In the nanomicroneedle group, the patients were aged 40.35 ± 7.39 years (range: 25 - 55 years), with the disease duration being 8.45 ± 4.77 months (range: 1 - 16 months) ; in the ultrasound group, the patients were aged 40.25 ± 7.76 years (range: 25 - 55 years), and their disease duration was 10.45 ± 5.07 months (range: 2 - 17 months) ; there were no significant differences in ages or disease duration between the two groups (both P > 0.05). At week 12, both groups demonstrated reduced MASI scores compared to baseline scores, and the MASI scores were significantly lower in the nanomicroneedle group ( M[ Q1, Q3]: 5.80[4.20, 9.35]) than in the ultrasound group (8.65[5.70, 10.80], Z = 2.50, P = 0.012). The overall response rate was significantly higher in the nanomicroneedle group (97.5%, 39/40) than in the ultrasound group (55.0%, 22/40; χ2 = 19.95, P < 0.001). The lateral facial VISIA brown spot scores were also significantly lower in the nanomicroneedle group (left side: 126.18 ± 36.54 points; right side: 138.50 ± 40.76 points) than in the ultrasound group (left side: 142.37 ± 32.40 points; right side: 157.13 ± 39.59 points; t = -2.10, -2.07, P = 0.039, 0.041, respectively). In the nanomicroneedle group, the pain scores were 4.12 ± 1.47 points, and varying severity of adverse reactions such as erythema, edema and dryness occurred after operation, all of which resolved spontaneously within 48 hours. No marked adverse reactions were observed in the ultrasound group. Conclusion:Nanomicroneedle-mediated delivery of tranexamic acid demonstrated superior clinical efficacy and favorable safety profiles compared to the ultrasound-mediated delivery, providing more options for the treatment of melasma.
