AIM: To analyze the factors influencing total corneal surgically induced astigmatism(SIA)following implantable collamer lens(ICL)implantation.METHODS:This prospective study enrolled 162 patients(162 eyes)who underwent ICL implantation at our hospital between July 2023 and January 2024. Based on preoperative assessment of anticipated postoperative residual astigmatism, different incisions were selected. Superior incision was selected for patients with expected residual astigmatism with the rule in 75 eyes, and temporal incision was selected for patients with expected residual astigmatism againist the rule in 87 eyes. Parameters including total corneal refractive power, incision length, internal ostium-to-visual axis distance, central corneal thickness, preoperative total corneal astigmatism, and corneal diameter were measured using the Pentacam anterior segment analyzer before and at 3 mo after surgery. Postoperative total corneal SIA was calculated based on the changes in total corneal refractive power. Multiple linear regression analysis was performed to assess the influence of the above parameters on postoperative total corneal SIA.RESULTS:A total of 162 cases(162 eyes)that implanted with ICL were included in the analysis, and 8 cases were lost to follow-up, with a loss rate of 4.9%. Eventually 154 cases(154 eyes)completed the research. The superior incision group comprised 72 cases(72 eyes), including 17 males and 55 females, with a mean age of 25.96±6.17 years, while the temporal incision group comprised 82 cases(82 eyes), including 20 males and 62 females, with a mean age of 27.79±6.47 years. No significant difference in postoperative total corneal SIA was observed between the two groups [0.31(0.21, 0.49)D vs. 0.27(0.13, 0.485)D, P=0.159]. Multiple linear regression analysis revealed that internal ostium-to-visual axis distance and preoperative total corneal astigmatism significantly influenced postoperative total corneal SIA in the superior incision group(P=0.001). The regression equation was: postoperative total corneal SIA=0.71-0.381×internal ostium-to-visual axis distance+0.16×preoperative total corneal astigmatism. No significant influencing factors for postoperative total corneal SIA were identified in the temporal incision group.CONCLUSION: During ICL implantation, the magnitude of total corneal SIA is comparable between superior and temporal incisions. For patients receiving a superior incision, the internal ostium-to-visual axis distance and preoperative total corneal astigmatism value can be used to quantitatively predict postoperative total corneal SIA to a certain extent, thereby aiding in the optimization of postoperative visual quality.

ObjectiveTo investigate the inhibitory effect of Biejiajian Pills （BJJW） on the growth of liver cancer， as well as its potential mechanism in mediating the AMP-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group， BJJW group （2.2 g/kg）， and metformin group （250 mg/kg）， and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment； HE staining was used to observe histopathological changes； the levels of reactive oxygen species （ROS） and adenosine triphosphate （ATP） in tumor tissue were measured； immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Tukey’s test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group， the BJJW group had a tumor inhibition rate of 45.73%， with significant reductions in both tumor volume and weight （P<0.01）. Pathological examination showed that compared with the model group， the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group， the BJJW group had a significant increase in ROS level （P<0.001） and a significant reduction in ATP level （P<0.001）， as well as significant increases in p-AMPK/AMPK ratio （0.81±0.20 vs 0.13±0.04， P<0.01） and p-ULK1/ULK1 ratio （0.69±0.17 vs 0.18±0.13， P<0.01） and a significant reduction in p-mTOR/mTOR ratio （1.34±0.16 vs 3.20±0.62， P<0.01）. ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction， increasing the level of ROS， reducing the level of ATP， and activating the AMPK/mTOR signaling pathway.

Liver cancer ranks among malignancies with high global incidence and mortality rates, presenting significant therapeutic challenges. The NF-κB signaling pathway plays a pivotal role in pathogenesis, progression, and treatment of liver cancer, where its aberrant activation is intricately linked to tumor cell proliferation and the dysregulation of apoptosis. In recent years, targeting the inhibition of this pathway has become an important research direction in the treatment of liver cancer. Traditional Chinese medicine (TCM), characterized by multicomponent nature and multitarget effects, exhibits unique advantages in the management of liver cancer. In this article, the regulatory mechanisms of the NF-κB signaling pathway in liver cancer are systematically reviewed, and the research progress on how TCM exerts antitumor effects by inhibiting this pathway and inducing apoptosis in liver cancer cells is summarized. This work provides a theoretical basis and new insights for the study of single compounds and compound formulations of TCM against liver cancer.

Compared with traditional therapies for chronic liver disease （CLD）， Bifidobacterium has the characteristics of multi-target intervention， high biosafety， and good host compatibility and provides new strategies for intervention of CLD progression in terms of microecological regulation. Various studies have shown that Bifidobacterium regulates liver homeostasis and exerts a therapeutic effect on CLD by regulating intestinal flora， maintaining antioxidation， promoting energy consumption， alleviating inflammation， improving glycolipid metabolism， and exerting an antitumor effect. This article systematically reviews the studies on Bifidobacterium in the treatment of CLD in China and globally， explores their different mechanisms， and elaborates on the interaction between related signaling pathways （such as the nuclear factor erythroid 2-related factor 2 signaling pathway and the adenosine monophosphate-activated protein kinase signaling pathway） and the liver， in order to provide a basis for probiotic intervention in liver pathology， as well as new ideas for the comprehensive treatment of CLD.

OBJECTIVE To systematically review medication-related risk factors for falls in older adults， to provide references for ensuring medication safety among older adults. METHODS A systematic search was conducted in PubMed， Embase， Web of Science， and CNKI for relevant literature published from database inception to November 1， 2025. Relevant studies on medication-related falls in older adults， both domestic and international， were included. Drug factors influencing falls in older adults were summarized and analyzed. RESULTS A total of 22 studies were included. Four major classes of fall-risk-increasing drugs were identified： psychotropic medications [12 studies， odds ratio （OR） range 1.500-5.790]， cardiovascular system drugs （5 studies， OR range 1.236-4.784）， analgesics （3 studies， OR range 1.500-4.490）， and hypoglycemic agents （3 studies， OR range 2.070-2.751）. Additionally， anticholinergic burden （1 study， OR was 2.610） and polypharmacy （7 studies， OR range 2.902-25.897 for the use of ≥4 medications） were identified as significant risk factors for falls. CONCLUSIONS Falls in older adults are significantly associated with psychotropic medications， cardiovascular system drugs， analgesics， and hypoglycemic agents， among which psychotropic medications pose the highest risk. Anticholinergic burden and polypharmacy are also important risk factors. In clinical practice， interventions should be implemented through deprescribing and risk monitoring to effectively reduce the risk of falls in older adults.

Objective To investigate the radon activity concentrations in subways of Nanning City and assess the average annual effective doses for subway staff and passengers due to radon exposure. Methods Sixty-three stations across the subway lines 2, 3, and 5 were selected as study sites. Radon activity concentrations were measured using the scintillation counting method with scintillation vials. Results The radon activity concentrations in subway lines 2, 3, and 5 were 7.9-24.4, 12.0-26.2, and 12.6-18.2 Bq/m³, respectively. The average radon activity concentrations for these three lines were (17.4 ± 4.6), (19.1 ± 4.1), and (14.6 ± 1.7) Bq/m³, respectively. Statistical analysis using SPSS 26.0 software revealed a significant difference in radon activity concentrations among these stations (P<0.01). Considering the data in previous research, the average radon activity concentration across all stations in the subway lines of Nanning City was determined to be 17.4 Bq/m³. The estimated average annual effective dose due to radon exposure was 0.131 mSv for subway staff and 0.033 mSv for passengers. Conclusion The radon activity concentrations in the subway lines of Nanning City were significantly lower than the national standard limit (400 Bq/m³). The annual effective doses from radon exposure for both subway staff and passengers were below the limits specified in the Basic Standards for Protection Against Ionizing Radiation and for the Safety of Radiation Sources (GB18871—2002). The health impact of radon and its progeny on subway staff and passengers in the subway lines of Nanning City was extremely low and can be considered negligible.

Objective To evaluate the levels and changes in occupational individual external radiation dose in non-medical nuclear utilization units in Nanning City, and to provide a basis for radiation protection in such units. Methods Thermoluminescent dosimeters were used to monitor individual radiation doses among radiation workers in 38 non-medical nuclear utilization units in Nanning City. The results were subjected to statistical analysis. Results From 2021 to 2023, a total of 3724 person-times were monitored in 38 non-medical nuclear utilization units in Nanning City. The mean annual effective dose was 0.101 mSv in 2021, 0.060 mSv in 2022, and 0.094 mSv in 2023, with a three-year average of 0.085 mSv, all well below the occupational exposure limit of 1.0 mSv. Significant differences in mean annual effective doses were observed across occupations and sexes (P<0.05). Female workers received significantly lower mean annual effective dose than male workers. Workers in the cement manufacturing industry had a significantly higher mean annual effective dose compared to those in government institutions and industrial flaw detection practitioners (F = 2.913, P<0.05). No significant differences were found among workers exposed to unsealed radioactive sources, sealed radioactive sources, and radiation-generating equipment (F = 0.585, P>0.05). Conclusion The occupational individual external radiation doses in non-medical nuclear utilization units in Nanning City are at low levels. There are no significant differences in mean annual effective dose across different nuclear utilization units. However, differences in occupational roles between males and females significantly affect the mean annual effective dose.

ObjectiveTo investigate the changes in the expression levels of Yes-associated protein 1 （YAP1） and human collagen type Ⅵ alpha 1 （COL6A1） in pancreatic cancer under hyperglycemic conditions and their association with prognosis. MethodsGEPIA database and R software were used to analyze the expression levels of YAP1 and COL6A1 and their correlation in pancreatic cancer， as well as their impact on the prognosis of patients with pancreatic cancer. The cBioPortal database was used to identify the co-expressed genes of YAP1 and COL6A1 in pancreatic cancer， and the gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses were performed. Quantitative real-time PCR and Western blot were used to measure the mRNA and protein expression levels of YAP1 and COL6A1 in human pancreatic cancer PANC-1 cells cultured under hyperglycemic or normoglycemic conditions. A nude mouse model of pancreatic cancer with type 2 diabetes was established， and immunohistochemistry was used to measure the expression of YAP1 and COL6A1 in subcutaneous tumor tissue. Clinical specimens and data of 96 patients with pancreatic cancer were collected from January 2016 to January 2020 in the First Affiliated Hospital of Guangxi Medical University， Guangxi Medical University Cancer Hospital and Wuming Hospital Affiliated to Guangxi Medical University. Among them， 48 patients with pancreatic cancer and diabetes were enrolled as study group， and 48 patients with pancreatic cancer alone were enrolled as control group； immunohistochemistry was used to measure the expression levels of YAP1 and COL6A1 in tissue samples from both groups， and their association with clinical indicators and survival outcomes was analyzed. The t-test was used for comparison of continuous data between groups， and the chi-square test or the Mann-Whitney U test was used for comparison of categorical data between groups； the Pearson correlation analysis was used for normally distributed continuous variables， while the Spearman correlation analysis was used for discontinuous variables or non-normally distributed variables. The Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison of survival rates. The Cox proportional hazards model was used to perform univariate and multivariate analyses. ResultsBoth YAP1 and COL6A1 were highly expressed in pancreatic cancer， with a strong correlation between them （r=0.85， P<0.001）， and they were associated with the poor prognosis of patients （hazard ratio ［HR］=1.8 and 1.5， both P<0.05）. YAP1 and COL6A1 were significantly correlated with 219 and 122 genes， respectively （r=0.83 and 0.86， both P<0.05）， and the GO and KEGG enrichment analyses showed that these genes affected the development and progression of pancreatic cancer through extracellular matrix-receptor interaction， the Hippo signaling pathway， and the phosphatidylinositol 3-kinase/protein kinase B signaling pathway. Quantitative real-time PCR and Western blot showed that there were significant increases in the mRNA and protein expression levels of YAP1 and COL6A1 in human pancreatic cancer PANC-1 cells under hyperglycemic conditions （mRNA expression： t=4.726 and 6.197， both P<0.05； protein expression： t=6.826 and 5.254， both P<0.05）. Immunohistochemistry showed that there were significant increases in the expression levels of YAP1 and COL6A1 in subcutaneous tumor tissue of nude mice， with a positive correlation between them （r=0.985， P<0.001）. For the clinical specimens of pancreatic cancer tissue， immunohistochemistry showed that there were significant increases in the positive expression levels of YAP1 and COL6A1 proteins in the study group， with a positive correlation between them （r=0.882， P<0.001）. The multivariate analysis of clinical data showed that lymph node metastasis （HR=0.083， 95% confidence interval ［CI］： 0.030 — 0.231， P<0.05）， distant organ metastasis （HR=0.166， 95%CI： 0.065 — 0.420， P<0.05）， YAP1 expression level （HR=2.027， 95%CI： 1.065 — 3.857， P<0.05）， and COL6A1 expression level （HR=2.044， 95%CI： 1.019 — 4.099， P<0.05） were independent influencing factors for the prognosis of patients with pancreatic cancer. The survival analysis showed that the high YAP1 expression group had a significantly lower 2-year survival rate than the low YAP1 expression group （6.82% vs 25.00%， χ²=16.382， P<0.001）， and the high COL6A1 expression group had a significantly lower 2-year survival rate than the low COL6A1 expression group （14.58% vs 18.75%， χ²=4.579， P=0.032）. ConclusionThe hyperglycemic environment promotes the high expression of YAP1 and COL6A1 in pancreatic cancer， which is associated with poor prognosis in patients.

OBJECTIVE To analyze trends in the burden of disease associated with falls from 1990 to 2023， identify risk factors for falls， and provide a reference for the development of measures to reduce the burden of disease associated with falls and the formulation of public health policies. METHODS Based on the data of 2023 from the Global Burden of Disease （GBD） database， the changes in fall-related prevalence， mortality， disability-adjusted life years （DALYs） and incidence in China and globally from 1990 to 2023 were analyzed， and the stratified analyses by gender， age and socio-demographic index （SDI） were conducted. The risk factors related to falls in 2023 were systematically analyzed， and the impact of multimorbidity and polypharmacy on the occurrence of falls by combining relevant literature evidence was explored. RESULTS & CONCLUSIONS Globally， the percentage changes in age-standardized rates of fall-related prevalence， mortality， DALYs and incidence from 1990 to 2023 were －2.4% （95%UI： －4.8% to －0.3%）， －7.8% （95%UI： －20.5% to 10.9%）， －10.6% （95%UI： －16.5% to －4.3%）， and －4.6% （95%UI： －8.1% to －0.8%）， respectively. However， in some regions， the percentage changes in age-standardized rates for these indicators were greater than 0 （e.g.， prevalence， mortality and DALYs in Australasia， and incidence in Andean Latin America）. In China， the percentage changes in age-standardized rates of fall-related mortality and DALYs from 1990 to 2023 were －18.3% （95%UI： －56.7% to 32.3%） and 1.9% （95%UI： －10.1% to 12.4%）， while the percentage changes in age-standardized rates of prevalence and incidence were 25.9% （95%UI： 20.2% to 32.0%） and 35.7% （95%UI： 28.5% to 44.1%）， respectively. Globally， in regions with high and medium-to-high SDI levels， the percentage changes in age-standardized rates of fall-related prevalence and incidence showed an upward trend， while DALYs showed a downward trend； however， the trend in mortality was unclear. In regions with a middle SDI level， the percentage changes in age-standardized rates of fall-related prevalence and incidence both showed an upward trend， while the trends in mortality and DALYs were unclear. In regions with low-to-medium SDI level， the percentage changes in age-standardized rate of fall-related prevalence， DALYs and incidence all showed a downward trend， while the trend in mortality was unclear； in regions with low SDI level， the trends for all above indicators were unclear. Correlation analyses of the burden of fall-related diseases in China and globally indicated that the risk of fall-related diseases was higher among younger and middle-to-older adult male populations， while women were concentrated in older age groups. Meanwhile， as the SDI levels increase， the percentage change in age-standardized rate of DALYs for fall-related diseases showed a clear upward trend， and this trend was more pronounced in high-SDI regions. Tobacco use， alcohol consumption， low bone density， and occupational risks were risk factors for falls， with low bone density and occupational risks contributing significantly （exceeding 20% in some regions）； multimorbidity and polypharmacy could also significantly increase the risk of falls. It is recommended that clinical settings establish a list of fall-risk increasing drugs and a warning system， improve medication reviews， strengthen medication education and adherence management， foster multidisciplinary collaboration， and develop medication strategies for specific patient populations to reduce the incidence of falls and alleviate the burden of disease.

Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.
