Background. Gastric cancer remains a major cancer globally. More than half of patients with gastric cancer undergo surgery in Taiwan; however, few large nationwide studies have investigated the effects of traditional Chinese medicine (TCM) on gastric cancer management after surgery. This study aimed to evaluate the effect of TCM on patients with gastric cancer following surgery and adjuvant chemotherapy in Taiwan and its prescription trends. Methods and Materials. The cohort sampling data set was obtained from the Registry of Catastrophic Illness Patient Database, a research database of patients with severe illnesses from the National Health Insurance Research Database, Taiwan. Patients who had received a new diagnosis of gastric cancer and had undergone surgery were enrolled. We matched TCM users and nonusers at a ratio of 1:3 based on the propensity score, and TCM users were also grouped into short-term and long-term users. Results. The number of TCM users and nonusers was 1701 and 5103 after applying the propensity score at a ratio of 1:3. Short-term users and long-term TCM users were independently associated with a decreased risk of death with HRs of 0.59 (95 confidence interval (CI), 0.550.65) and 0.41 (95 CI, 0.360.47), respectively, compared with TCM nonusers. We also obtained similar results when we adjusted for covariates in the main model, as well as each of the additional listed covariates. We also observed similar HR trends in short-term users and long-term TCM users among men and women aged <65years and 65 years. The most commonly prescribed single herb and herbal formula in our cohort were Hwang-Chyi (Radix Hedysari; 11.8) and Xiang-Sha-Liu-Jun-Zi-Tang (15.5), respectively. Conclusion. TCM use was associated with higher survival in patients with gastric cancer after surgery and adjuvant chemotherapy. TCM could be used as a complementary and alternative therapy in patients with gastric cancer after surgery and adjuvant chemotherapy.

Background: Numerous studies have revealed that statins have antitumor effects in vivo and in vitro. However, few studies have explored the relationship between statin use and the mortality of gastric cancer (GC) patients after treatments. This study examines the relationship between statin use and the overall survival (OS) of GC patients after surgery and adjuvant chemotherapy, using data from the nationwide cohort database of Taiwan. Methods: All patients newly diagnosed with GC from 1999 to 2008 in Taiwan were identified from the Registry of Catastrophic Illness Patients Database. Through propensity score matching, statin users were matched to statin non-users at a 1:4 ratio. The relationship between statin use and the OS of patients with GC was estimated through Cox regression models. Results: The study cohort included 1835 patients with GC who had received therapies during the study period. The death numbers among statin users (defined as those who used more than 28 cumulative defined daily doses (cDDDs)) and statin non-users were 138 and 895, respectively. A dose–response association was noted between statin use and the OS of patients with GC after treatments. The adjusted hazard ratios were 0.62 (95% confidence intervals (CI), 0.50–0.78) and 0.34 (95% CI, 0.26–0.45) for statin users administered 28–167 cDDDs and >168 cDDDs, respectively, compared with no statin use (<28 cDDDs). Conclusions: This study highlights that statin use may dose-dependently improve the OS of patients with GC after surgery and adjuvant chemotherapy in Taiwan. Additional studies are required to confirm the efficacy and safety of statin use.

Background: Peritonsillar abscess (PTA) is an infectious emergency in the head and neck, and patients with end-stage renal disease (ESRD) have an immunocompromised status. However, no relevant research has focused on the ESRD–PTA relationship. This study explored PTA in ESRD patients and their prognosis. Methods: We identified 157,026 patients diagnosed as having ESRD over January 1997 to December 2013 from Taiwan’s National Health Insurance Research Database (NHIRD). Each patient with ESRD (hereafter, patients) was matched with one control without chronic kidney disease (CKD; hereafter, controls) by sex, age, urbanization level, and income. Next, PTA incidence until death or the end of 2013 was compared between the two groups, and the relative risk of PTA was analyzed using a multiple logistic regression model. Results: The patients had a significantly higher PTA incidence than did the controls (incidence rate ratio: 2.02, 95% confidence interval [CI]: 1.40–2.91, p < 0.001). The Kaplan–Meier analysis revealed that the patients had a higher cumulative incidence of PTA than did the controls (p < 0.001). In Cox regression analysis, the patients had nearly twofold higher PTA risk (adjusted hazard ratio [HR]: 1.98, 95% CI: 1.37–2.86, p < 0.001). The between-group differences in the PTA-related hospital stay length (8.1 ± 10.3 days in patients and 5.7 ± 4.6 days in controls, p = 0.09), consequent deep-neck infection complication (4.2% in patients and 6.3% in controls, p = 0.682), and mortality (0.0% in both groups) were nonsignificant. Conclusions: Although ESRD does not predict a poor prognosis of PTA, it is an independent PTA risk factor.

Astragalus polysaccharides (APSs), the compounds extracted from the common herb Astragalus membranaceus, have been extensively studied for their antitumor properties. In this study, we investigated the effect of APS on lung adenocarcinoma A549 cells. The effects of APS and the anti-diabetic drug metformin on apoptosis and ferroptosis were compared. Furthermore, the combination treatment of APS and metformin was also investigated. We found that APS not only reduced the growth of lung cancer cells but also had a synergistic effect with metformin on A549 cells. The study results showed that it may be promising to use APS and metformin as a combination therapy for the treatment of lung adenocarcinoma.

Intussusception is frequently observed pediatric emergency that is often followed by recurrent intussusception after initial treatment. This study investigated the risk factors associated with recurrent intussusception in children aged ≤ 3 years. Between January 2007 and December 2015, a cohort study was conducted by linking the Taiwan Maternal and Child Health Database to the Birth Certificate Application database and the National Health Insurance Research Database in Taiwan. Patients aged ≤ 3 years with intussusception diagnosis and related treatment were included in our study. Multivariable logistic regression was used to analyze the risk factors associated with recurrent intussusception. In total, 5341 children with intussusception aged ≤ 3 years were enrolled in our cohort. The adjusted odds ratio (aOR) for recurrent intussusception in children aged 2 to 3 years was 0.62 (95% confidence interval [CI]: 0.47–0.82) compared with children aged < 1 year, and surgery decreased the risk of recurrent intussusception (aOR = 0.64, 95% CI: 0.46–0.88). Male patients had higher risk of recurrent intussusception than female patients had (aOR = 1.41, 95% CI: 1.13–1.75). Higher birth weight may increase the risk of recurrent intussusception, but this association was not statistically significant. Furthermore, gestational age did not seem to affect the risk of recurrent intussusception. Surgical treatment and delayed onset of intussusception are associated with a reduced risk of recurrent intussusception; males are associated with increased risk of recurrent intussusception. In addition, we suggest that in early infancy, patients who received non-surgical treatment as the initial treatment for intussusception should be closely followed up for potential recurrence of intussusception.

Prostate cancer remains a significant global health challenge, necessitating the development of novel therapeutic approaches. This study investigated the therapeutic potential of the Antrodia cinnamomea formula (XIANZHIFANG formula, XZF), comprising Antrodia cinnamomea, Sanghuangporus sanghuang, Ganoderma lucidum, Ganoderma sinense, and Inonotus obliquus, in prostate cancer treatment. HPLC analysis confirmed the presence of key triterpenoids, including Antcin A, B, C, K, and Zhankuic acid B, C, and 4,7-dimethoxy-5-methyl-1,3-benzodioxole. Cytotoxicity assays demonstrated that XZF (50–200 μg/mL) exhibited selective activity, maintaining viability in non-cancerous 293T-cells while enhancing the viability of activated CD8+ and CD4+ T-cells in a dose-dependent manner. XZF significantly reduced PD-1 expression in CD8+ T-cells but not in CD4+ T-cells and inhibited the PD-L1/PD-1 interaction, achieving 93% inhibition at 200 μg/mL. Furthermore, when combined with atezolizumab (1 μg/mL), XZF demonstrated complete blockade of PD-L1/PD-1 interaction. In prostate cancer cells, XZF exhibited differential antiproliferative effects. In PC-3 cells, XZF significantly reduced viability across a concentration range of 25–200 μg/mL, whereas DU145 cells showed only partial inhibition at higher concentrations (100–200 μg/mL). LNCaP cells exhibited a dose-dependent reduction in viability, mirroring the response pattern of PC-3 cells. Conditioned medium from XZF-treated macrophages, particularly human THP-1 cells, significantly suppressed the viability and migration of prostate cancer cells in a dose-dependent manner. Notably, the conditioned medium from XZF-treated THP-1 cells exhibited a stronger inhibitory effect on prostate cancer cell viability and migration compared to murine RAW 264.7 macrophages. These findings indicate that XZF exerts its therapeutic potential through multiple mechanisms, including direct antiproliferative effects on cancer cells, enhancement of T-cell responses, modulation of immune checkpoint pathways, and macrophage-mediated suppression of prostate cancer cell survival and migration. The pronounced effects observed in human macrophage models suggest a promising avenue for further investigation in clinical settings, particularly in combination with existing immunotherapies.
