Objective To analyze the disease burden of early-onset colorectal cancer (EOCRC) at the global, regional, and national levels from 1990 to 2021, and to predict the disease burden trend from 2022 to 2026. Methods Based on the Global Burden of Disease (GBD) database, the incidence, mortality, and disability-adjusted life year (DALY) rate of EOCRC across 204 countries and regions from 1990 to 2021 were obtained. The time trends of these indicators were assessed by calculating the estimated annual percentage change (EAPC), and the contributions of ten risk factors to the EOCRC burden were analyzed. The autoregressive integrated moving average (ARIMA) model was used to predict the disease burden from 2022 to 2026. Results From 1990 to 2021, the number of new global EOCRC cases increased from 107 310 to 211 890, with the incidence rising from 3.96 to 5.37 per 100 000 people. In 2021, global EOCRC incidence, mortality, and DALY rate increased with age; males had higher rates than females in terms of incidence, mortality, and DALY rate in all age groups. In 2021, East Asia had the highest number of new cases, deaths, and DALY. From 1990 to 2021, the global EAPC for incidence rate was 0.96%, and death rate was –0.38%. ARIMA model indicated that from 2022 to 2026, the global incidence of EOCRC would continue to rise, while mortality and DALY rate would be expected to decline. Conclusions The disease burden of EOCRC has significantly increased globally from 1990 to 2021, with notable regional, age, and sex differences. By 2026, the mortality and DALY rate of EOCRC will decline, while the incidence is expected to further increase, highlighting the urgency of taking active measures to address the growing trend of EOCRC.

Objective To explore the feasibility and clinical value of endoscopic resection of duodenal papilla tumors with a maximum diameter greater than 3 cm. Methods A retrospective analysis was conducted on the clinical data of all 12 patients who underwent endoscopic resection of duodenal papilla tumors at the Endoscopy Center of Zhongshan Hospital (Xuhui Hospital), Fudan University and Rongcheng Hospital of Traditional Chinese Medicine from September 2017 to May 2023. The size of the tumors all exceeded 3 cm. Results All 12 patients successfully completed the operation, with a complete resection rate of 91.7% (11/12) and an en-bloc resection rate of 91.7% (11/12). One patient experienced delayed bleeding due to unclosed wound during operation and received endoscopic hemostasis; 11 cases underwent partial wound closure operation with pancreatic and biliary stent placement, without perforation or postoperative stenosis. Among them, 2 cases (18.2%) experienced delayed bleeding and received endoscopic hemostasis treatment. After operation, 1 case (8.3%) experienced nausea, vomiting, upper abdominal discomfort, and elevated blood amylase levels, who was later treated conservatively. During the mean follow-up period of 30.5 (1.0-69.0) months, 1 patient experienced recurrence and underwent surgical resection. Conclusions Endoscopic resection of duodenal papilla tumors can treat large diameter duodenal papilla tumors exceeding 3 cm, but postoperative complications may occur and require special attention. Postoperative placement of pancreatic and biliary stents and wound closure may reduce the incidence of complications.

Osteosarcoma (OS) is the most prevalent primary malignant bone tumor affecting children and adolescents. Despite ongoing research efforts, the 5-year survival rate has remained stagnant for many years, highlighting the critical need for novel drug development to enhance current treatment protocols. Ziyuglycoside II (ZYG II), a triterpenoid saponin extracted from S. officinalis, has recently demonstrated antitumor properties. This study evaluates the antitumor effect of ZYG II on osteosarcoma and elucidates its mechanism of action through the co-regulation of p53 and estrogen-related receptor gamma (ESRRG), which inhibits disease progression. The research employs in vitro experiments using multiple established osteosarcoma cell lines, as well as in vivo studies utilizing a nude mouse model of orthotopic xenograft osteosarcoma. Additionally, ESRRG shRNA was used to construct stable ESRRG-reducing OS cell lines to investigate the molecular mechanism by which ZYG II exerts its anti-osteosarcoma effects through the co-regulation of ESRRG and p53. Results indicate that ZYG II administration led to decreased OS cell viability and reduced tumor volumes. Furthermore, cell cycles were arrested at the G₀/G₁ phase, while the proportion of apoptotic cells increased. Expression of p53, ESRRG, p21, Bax, Cleaved Caspase-9, and Cleaved Caspase-3 proteins increased, while expression of CDK4, Cyclin D1, and Bcl-2 proteins decreased. Multiple ZYG II and ESRRG docking patterns were simulated through molecular docking. Comparing the pharmacodynamic response of ZYG II to OS cell lines with reduced ESRRG and normal expression demonstrated that ZYG II inhibits osteosarcoma progression, induces cell cycle arrest, and promotes cell apoptosis through the coordination of p53 and ESRRG. In conclusion, ZYG II inhibits osteosarcoma progression, leads to cell cycle arrest, and promotes cell apoptosis through synergistic regulation of p53 and ESRRG.

OBJECTIVE:To systematically evaluate the correlation between phase angle and sarcopenia and its diagnostic indexes.METHODS:The PubMed,EMbase,Cochrane Library,Web of Science,CNKI,WanFang Data,VIP and SinoMed databases were electronically searched to collect studies on the correlation between phase angle and sarcopenia and its diagnostic indexes from database inception to May 8,2024. Two reviewers independently screened literature,extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 and Stata 14.0 software. RESULTS:A total of 50 eligible articles were included. Meta-analysis results showed that compared with the non-sarcopenic population,the phase angle was significantly reduced in sarcopenic patients[standardized mean difference (SMD)=-0.99,95％ confidence interval (CI) (-1.09,-0.90),P<0.00001]. The results of subgroup analysis indicated that the difference of phase angle was more significant in patients with severe sarcopenia and Asian sarcopenia. Moreover,reduction in the phase angle was more obvious in patients with malignant tumors and respiratory diseases with sarcopenia. And skeletal muscle mass index (Pearson's r=0.565,P<0.00001),grip strength (Pearson's r=0.446,P<0.00001),and gait speed (Pearson's r=0.405,P<0.00001) all showed a moderate positive correlation with phase angle. However,appendicular skeletal muscle mass index showed a very weak positive correlation with phase angle (Pearson's r=0.139,P=0.02). CONCLUSION:Phase angle has a significant difference between sarcopenia and non-sarcopenia population,and it is correlated with the diagnostic indexes of sarcopenia to different extents. It suggests that phase angle has some clinical values in the objective diagnosis of sarcopenia. However,the results may be influenced by some factors such as sarcopenia severity and detection instruments of phase angle. Due to the limited quality and quantity of the included studies,more high-quality studies are needed to verify the above conclusion.

Congenital heart diseases (CHDs) seriously affect human health, and genetic mutation is closely related to the occurrence of CHDs. In the process of assisted reproduction, the use of methods such as polar body biopsy, blastomere biopsy and blastocyst biopsy, combined with single-cell DNA amplification and high-throughput sequencing technology, can accurately detect pathogenic mutations associated with single-gene genetic diseases in pre-implantation embryos. T-box transcription factor 5 (TBX5) is an important transcription factor for heart and upper limb development. It is reported 227 TBX5 mutations are related to CHDs. Preimplantation genetic testing for monogenic disease (PGT-M) to detect CHD-related TBX5 mutations in embryos is of great significance for preventing the occurrence of CHDs. In this review, we systematically summarized the TBX5 mutation information, and analyzed the deleterious effects of TBX5 missense mutations based on familial genetic data, animal models, induced pluripotent stem cell disease models and prediction software to provide references for the detection of CHD-related TBX5 mutations using PGT-M.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of polyisobutylene （PIB）-type Gutong plaster （called “PIB Gutong plaster” for short） versus non-steroidal anti-inflammatory drugs （NSAIDs） in the treatment of osteoarthritis in Chinese adults. METHODS Based on a real-world study， after propensity score matching， the decrease in pain visual simulation score， utility increase， time to pain resolution， time to return to normal range of motion and total adverse events of PIB Gutong plaster versus three NSAIDs （celecoxib， diclofenac sodium， and ibuprofen） were evaluated. Cost-utility analysis was used to calculate the incremental cost-effectiveness ratio （ICER） of patients using PIB Gutong plaster versus the three NSAIDs from the perspective of the whole society， and sensitivity analysis was carried out. RESULTS In terms of effectiveness， the recovery time of joint activity in PIB Gutong plaster group was significantly longer than that in celecoxib group， the decrease in VAS score of PIB Gutong plaster was significantly higher than that of ibuprofen but significantly lower than that of diclofenac sodium； the time of pain disappearance was longer than that in diclofenac sodium group and ibuprofen group， and the increase in health utility was significantly lower than that in diclofenac sodium group （P＜0.05）. In terms of safety， there were no significant differences in the incidence and severity of adverse events of PIB Gutong plaster， compared with the three NSAIDs， without statistical significance （P＜0.05）. In terms of cost-effectiveness， compared with celecoxib and diclofenac sodium， PIB Gutong plaster was dominant. Compared with ibuprofen， the ICER value of PIB Gutong plaster was 178 611.58 yuan/QALY， indicating that at the current price， PIB Gutong plaster was cost-effective if the threshold was 3 times GDP per capita. The results of sensitivity analysis were consistent with those of basic analysis. CONCLUSIONS The efficacy of PIB Gutong plaster was better than that of ibuprofen， similar to that of celecoxib， but worse than that of diclofenac sodium， the safety was consistent with the three NSAIDs， and the cost-effectiveness of PIB Gutong plaster needs to be improved.

ObjectiveTo investigate the protective effect of cytochrome P4502D6 （CYP2D6） and cytochrome P4503A4 （CYP3A4）， key enzymes of drug metabolism in liver， on acute liver injury in water extract of Glycyrrhizae Radix et Rhizoma （WEOGRR）. MethodHealthy male Kunming mice were divided into normal group， model group， WEOGRR low-， medium- and high-dose groups （5， 10， 15 g·kg^-1·d^-1） and positive drug group （diammonium glycyrrhizinate， 75 mg·kg^-1·d^-1）， with 10 in each group. One week after preventive administration， acute liver injury model was induced by single intragastric administration of 270 mg·kg^-1 Tripterygium Glycosides tablets， and samples were collected after 18 h. The pathological changes of liver were observed by hematoxylin-eosin （HE） staining. Serum liver function indexes including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， γ-glutamyl transpeptadase （γ-GT）， alkaline phosphatase （ALP）， and total bilirubin （TBIL） as well as the levels of oxidative stress indexes including malondialdehyde （MDA） and superoxide dismutase （SOD） in hepatocytes were determined by biochemical method. Real-time polymerase chain reaction （Real-time PCR） and Western blot were performed to detect the mRNA and protein expression levels of CYP2D6 and CYP3A4， respectively. ResultCompared with normal group， model group had significant hepatocyte swelling and inflammatory cell infiltration （P<0.01）， increased AST， ALT， γ-GT， ALP and TBIL （P<0.05）， elevated MDA and decreased SOD （P<0.01） as well as down-regulated mRNA and protein expression levels of CYP2D6 and CYP3A4 （P<0.05）. Compared with the model group， the normal group had intact liver structure without obvious abnormality， and the WEOGRR groups and positive drug group presented alleviated hepatocyte swelling and inflammatory cell infiltration （P<0.01）， reduced AST， ALT， γ-GT， ALP and TBIL （P<0.01）， lowered MDA and increased SOD （P<0.01） as well as up-regulated expression levels of CYP2D6 and CYP3A4 （P<0.01）. ConclusionThe protective effect of WEOGRR on acute liver injury induced by Tripterygium glycosides tablets may be related to reducing the contents of AST， ALT， γ-GT， ALP and TBIL in serum， inhibiting MDA and increasing the activity of SOD in liver cells， and enhancing the activities of CYP2D6 and CYP3A4， thus accelerating the metabolism of toxic substances.

Another 10 mice were used to detect the transfection effect of AAV-Sestrin2, and the left 6 mice were used for mtDNA extraction. The model of endotoxemia was developed by intraperitoneal injection of LPS 10 mg/kg. mtDNA 5 mg/kg was intraperitoneally injected in mtDNA group, and mtDNA 5 mg/kg was intraperitoneally injected at 30 min after LPS injection in M group.AAV-Sestrin2 150 μl was injected via the tail vein in MS group, and the equal volume of AAV-NC was injected via the tail vein in MC and NC groups. Four weeks after virus injection, LPS 10 mg/kg was intraperitoneally injected and 30 min later mtDNA 5 mg/kg was intraperitoneally injected in MS and MC groups. Blood samples were collected at 24 h after LPS injection for determination of serum creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) activities (by biochemical assay), concentrations of serum cardiac troponin I (cTnI), interleukin-18 (IL-18) and interleukin-1beta (IL-1β)(by enzyme-linked immunesorbent assay), and expression of mtDNA (by quantitative real-time polymerase chain reaction). The animals were sacrificed after the end of blood sampling and myocardial tissues were obtained for determination of the contents of reactive oxygen species (ROS), total antioxidant capacity (T-AOC), and adenosine triphosphate (ATP) and expression of NOD-like receptor associated protein 3 (NLRP3), active subunit p20 of caspase-1 (caspase-1p20) and apoptosis-associated microprotein (ASC) in myocardial tissues (by Western blot) and for microscopic examination of the pathological changes after HE staining (with a light microscope). Results:Compared with N group, the levels of CK-MB, LDH, cTnI, IL-1β and IL-18 in serum were significantly increased, the expression of mtDNA was up-regulated, the ROS content in myocardial tissues was increased, the T-AOC and ATP contents in myocardial tissues were decreased, the expression of NLRP3, caspase-1p20 and ASC in the myocardial tissues was up-regulated( P<0.05), and the pathological changes of myocardial tissues were aggravated in L group and mtDNA group.Compared with L group and mtDNA group, the levels of CK-MB, LDH, cTnI, IL-1β and IL-18 in serum were significantly increased, the expression of mtDNA was up-regulated, the ROS content in myocardial tissues was increased, the T-AOC and ATP contents in myocardial tissues were decreased, the expression of NLRP3, caspase-1p20 and ASC in the myocardial tissues was up-regulated( P<0.05), and the pathological changes of myocardial tissues were aggravated in M group. Compared with M group, the levels of CK-MB, LDH, cTnI, IL-1β and IL-18 in serum were significantly decreased, the expression of mtDNA was down-regulated, the ROS content in myocardial tissues was decreased, the T-AOC and ATP contents in myocardial tissues were increased, the expression of NLRP3, caspase-1p20 and ASC in the myocardial tissues was down-regulated( P<0.05), and the pathological changes of myocardial tissues were significantly attenuated in MS group. Conclusions:Sestrin2 can reduce endotoxin-induced myocardial injury in mice by alleviating mitochondrial damage, inhibiting oxidative stress, protecting mtDNA from oxidative damage, and then inhibiting mtDNA-NLRP3 inflammasome pathway.
