Abstract
Psoriasis is a chronic inflammatory dermatological disease, and there is a lack of understanding of the genetic factors involved in psoriasis in Taiwan. To establish associations between genetic variations and psoriasis, a genome‑wide association study was performed in a cohort of 2,248 individuals with psoriasis and 67,440 individuals without psoriasis. Using the ingenuity pathway analysis software, biological networks were constructed. Human leukocyte antigen (HLA) diplotypes and haplotypes were analyzed using Attribute Bagging (HIBAG)‑R software and chi‑square analysis. The present study aimed to assess the potential risks associated with psoriasis using a polygenic risk score (PRS) analysis. The genetic association between single nucleotide polymorphisms (SNPs) in psoriasis and various human diseases was assessed by phenome‑wide association study. METAL software was used to analyze datasets from China Medical University Hospital (CMUH) and BioBank Japan (BBJ). The results of the present study revealed 8,585 SNPs with a significance threshold of P<5x10‑8, located within 153 genes strongly associated with the psoriasis phenotype, particularly on chromosomes 5 and 6. This specific genomic region has been identified by analyzing the biological networks associated with numerous pathways, including immune responses and inflammatory signaling. HLA genotype analysis indicated a strong association between HLA‑A*02:07 and HLA‑C*06:02 in a Taiwanese population. Based on our PRS analysis, the risk of psoriasis associated with the SNPs identified in the present study was quantified. These SNPs are associated with various dermatological, circulatory, endocrine, metabolic, musculoskeletal, hematopoietic and infectious diseases. The meta‑analysis results indicated successful replication of a study conducted on psoriasis in the BBJ. Several genetic loci are significantly associated with susceptibility to psoriasis in Taiwanese individuals. The present study contributes to our understanding of the genetic determinants that play a role in susceptibility to psoriasis. Furthermore, it provides valuable insights into the underlying etiology of psoriasis in the Taiwanese community.

Abstract
Osteoporosis, a condition defined by low bone mineral density (BMD) (typically < -2.5 SD), cause a higher fracture risk and lead to significant economic, social, and clinical impacts. Genome-wide studies mainly in Caucasians have found many genetic links to osteoporosis, fractures, and BMD, with limited research in East Asians. We investigated the genetic aspects of BMD in 86,716 individuals from the Taiwan Biobank and their causal links to health conditions within East Asians. A genome-wide association study (GWAS) was conducted, followed by observational studies, polygenic risk score assessments, and genetic correlation analyses to identify associated health conditions linked to BMD. GWAS and gene-based GWAS studies identified 78 significant SNPs and 75 genes related to BMD, highlighting pathways like Hedgehog, WNT-mediated, and TGF-β. Our cross-trait linkage disequilibrium score regression analyses for BMD and osteoporosis consistently validated their genetic correlations with body mass index (BMI) and type 2 diabetes (T2D) in East Asians. Higher BMD was linked to lower osteoporosis risk but increased BMI and T2D, whereas osteoporosis linked to lower BMI, waist circumference, HbA1c, and reduced T2D risk. Bidirectional Mendelian randomization (MR) analyses revealed that a higher BMI causally increases BMD in East Asians. However, no direct causal relationships were found between BMD and T2D, or between osteoporosis and either BMI or T2D. This study identified key genetic factors for bone health in Taiwan, and revealed significant health conditions in East Asians, particularly highlighting the genetic interplay between bone health and metabolic traits like T2D and BMI.

Abstract
A novel chitosan/sodium hyaluronate/iridium (CHI/SH/Ir) hydrogel nanocomposite with a unique microstructure containing vertically aligned pores is fabricated via an electrophoresis technique. The formation of orderly vertical pores in CHI/SH/Ir hydrogel nanocomposite is due to the confinement of hydrogen bubbles produced from the water electrolysis during electrophoresis that limits their lateral movement and coalescence. In a wet state, the diameter for the vertical pores is 600-700 μm. With a thickness of 500 μm, the CHI/SH/Ir hydrogel nanocomposite exhibits a porosity of 76.7 % and a water uptake of 350 %. Its tensile strength is almost doubled to 8.7 MPa, as compared to that of counterpart without the addition of iridium. In CHI/SH/Ir hydrogel nanocomposite, the iridium nanoparticles are homogeneously distributed with an average size of 3 nm. The CHI/SH/Ir electrophoresis suspension exhibits a negligible cytotoxicity. In cell migration test using the human keratinocytes HaCaT cells, the CHI/SH/Ir hydrogel nanocomposite reveals a relative migration of 122.15 ± 9.02 % (p < 0.001) as compared to the blank sample. The presence of vertically aligned pores with the use of SH and iridium nanoparticles indicates a promising opportunity in wound healing application.

Abstract
BACKGROUND/AIM Matrix metalloproteinase-9 (MMP-9) expression is upregulated in various diseases, including lung cancer. However, the role of MMP-9 genotype in lung cancer susceptibility remains uncertain. This study aimed to clarify the contribution of MMP-9 promoter rs3918242 genotypes to the risk of lung cancer in Taiwan. MATERIALS AND METHODS The MMP-9 rs3918242 genotypes of 358 lung cancer patients and 716 healthy controls were determined using polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS Individuals carrying the variant CT or TT genotype of MMP-9 rs3918242 did not demonstrate an increased risk of lung cancer compared to wild-type CC carriers [odds ratio (OR)=1.11 and 1.85, 95% confidence interval (95%CI)=0.82-1.48 and 0.91-3.76; p=0.5541 and 0.1280, respectively]. Moreover, individuals carrying the T allele did not show a higher lung cancer risk compared to those with the C allele (OR=1.21, 95%CI=0.95-1.54, p=0.1444). However, a significant association was observed between the MMP-9 rs3918242 TT genotype and lung cancer risk among non-smokers (OR=5.48, 95%CI=1.31-22.89, p=0.0181). CONCLUSION The presence of the TT genotype for MMP-9 rs3918242 may indicate an elevated risk of lung cancer among non-smokers.

Abstract
Objectives The protective effects and related mechanisms of Jing-Si herbal tea (JSHT) were investigated in cellular damage mediated by pro-inflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, on normal human lung fibroblast by multiomic platform analysis. Materials and Methods The in silico high-throughput target was analyzed using pharmacophore models by BIOVIA Discovery Studio 2022 with ingenuity pathway analysis software. To assess cell viability, the study utilized the MTT assay technique. In addition, the IncuCyte S3 ZOOM System was implemented for the continuous monitoring of cell confluence of JSHT-treated cytokine-injured HEL 299 cells. Cytokine concentrations were determined using a Quantibody Human Inflammation Array. Gene expression and signaling pathways were determined using next-generation sequencing. Results In silico high-throughput target analysis of JSHT revealed ingenuity in canonical pathways and their networks. Glucocorticoid receptor signaling is a potential signaling of JSHT. The results revealed protective effects against the inflammatory cytokines on JSHT-treated HEL 299 cells. Transcriptome and network analyses revealed that induction of helper T lymphocytes, TNFSF12, NFKB1-mediated relaxin signaling, and G-protein coupled receptor signaling play important roles in immune regulatory on JSHT-treated cytokine-injured HEL 299 cells. Conclusion The findings from our research indicate that JSHT holds promise as a therapeutic agent, potentially offering advantageous outcomes in treating virus infections through various mechanisms. Furthermore, the primary bioactive components in JSHT justify extended research in antiviral drug development, especially in the context of addressing coronavirus.

Abstract
We conducted the first genome-wide association study (GWAS) of prostate cancer (PCa) in Taiwan with 1844 cases and 80,709 controls. Thirteen independent single-nucleotide polymorphisms (SNPs) reached genome-wide significance (p < 5 × 10-8 ). Among these, three were distinct from previously identified loci: rs76072851 in CORO2B gene (15q23), odds ratio (OR) = 1.54, 95% confidence interval (CI), 1.36-1.76, p = 5.30 × 10-11 ; rs7837051, near two long noncoding RNA (lncRNA) genes, PRNCR1 and PCAT2 (8q24.21), OR = 1.41 (95% CI, 1.31-1.51), p = 8.77 × 10-21 ; and rs56339048, near an lncRNA gene, CASC8 (8q24.21), OR = 1.25 (95% CI, 1.16-1.35), p = 2.14 × 10-8 . We refined the lead SNPs for two previously identified SNPs in Taiwanese: rs13255059 (near CASC8), p = 9.02 × 10-43 , and rs1456315 (inside PRNCR1), p = 4.33 × 10-42 . We confirmed 35 out of 49 GWAS-identified East Asian PCa susceptibility SNPs. In addition, we identified two SNPs more specific to Taiwanese than East Asians: rs34295433 in LAMC1 (1q25.3) and rs6853490 in PDLIM5 (4q22.3). A weighted genetic risk score (GRS) was developed using the 40 validated SNPs and the area under the receiver-operating characteristic curve for the GRS to predict PCa was 0.67 (95% CI, 0.63-0.71). These identified SNPs provide valuable insights into the molecular mechanisms of prostate carcinogenesis in Taiwan and underscore the significant role of genetic susceptibility in regional differences in PCa incidence.

Abstract
STUDY QUESTION Are there associations of age at menarche (AAM) with health-related outcomes in East Asians? SUMMARY ANSWER AAM is associated with osteoporosis, Type 2 diabetes (T2D), glaucoma, and uterine fibroids, as demonstrated through observational studies, polygenic risk scores, genetic correlations, and Mendelian randomization (MR), with additional findings indicating a causal effect of BMI and T2D on earlier AAM. WHAT IS KNOWN ALREADY Puberty timing is linked to adult disease risk, but research predominantly focuses on European populations, with limited studies in other groups. STUDY DESIGN, SIZE, DURATION We performed an AAM genome-wide association study (GWAS) with 57 890 Han Taiwanese females and examined the association between AAM and 154 disease outcomes using the Taiwanese database. Additionally, we examined genetic correlations between AAM and 113 diseases and 67 phenotypes using Japanese GWAS summary statistics. PARTICIPANTS/MATERIALS, SETTING, METHODS We performed AAM GWAS and gene-based GWAS studies to obtain summary statistics and identify potential AAM-related genes. We applied phenotype, polygenic risk scores, and genetic correlation analyses of AAM to explore health-related outcomes, using multivariate regression and linkage disequilibrium score regression analyses. We also explored potential bidirectional causal relationships between AAM and related outcomes through univariable and multivariable MR analyses. MAIN RESULTS AND THE ROLE OF CHANCE Fifteen lead single-nucleotide polymorphisms and 24 distinct genes were associated with AAM in Taiwan. AAM was genetically associated with later menarche and menopause, greater height, increased osteoporosis risk, but lower BMI, and reduced risks of T2D, glaucoma, and uterine fibroids in East Asians. Bidirectional MR analyses indicated that higher BMI/T2D causally leads to earlier AAM. LIMITATIONS, REASONS FOR CAUTION Our findings were specific to Han Taiwanese individuals, with genetic correlation analyses conducted in East Asians. Further research in other ethnic groups is necessary. WIDER IMPLICATIONS OF THE FINDINGS Our study provides insights into the genetic architecture of AAM and its health-related outcomes in East Asians, highlighting causal links between BMI/T2D and earlier AAM, which may suggest potential prevention strategies for early puberty.

Abstract
Immunoglobulin E (IgE) synthessis is highly related to a variety of atopic diseases, and several genome-wide association studies (GWASs) have demonstrated the association between genes and IgE level. In this study, we conducted the largest genome-wide association study of IgE involving a Taiwanese Han population. Eight independent variants exhibited genome-wide significance. Among them, an intronic SNP of CD28, rs1181388, and an intergenic SNP, rs1002957030, on 11q23.2 were identified as novel signals for IgE. Seven of the loci were replicated successfully in a meta-analysis using data on Japanese population. Among all the human leukocyte antigen (HLA) regions, HLA-DQA1*03:02 - HLA-DQB1*03:03 was the most significant haplotype (OR = 1.25, SE = 0.02, FDR = 1.6 × 10-14), corresponding to HLA-DQA1 Asp160 and HLA-DQB1 Leu87 amino acid residues. The genetic correlation showed significance between IgE and allergic diseases including asthma, atopic dermatitis, and pollinosis. IgE PRS was significantly correlated with total IgE levels. Furthermore, the top decile IgE polygenic risk score (PRS) group had the highest risk of asthma for the Taiwan Biobank and Biobank Japan cohorts. IgE PRS may be used to aid in predicting the occurrence of allergic reactions before symptoms occur and biomarkers are detectable. Our study provided a more comprehensive understanding of the impact of genomic variants, including complex HLA alleles, on serum IgE levels.

Abstract
Objectives: Primary cardiac involvement (SSc-PHI) in systemic sclerosis is an important prognostic factor. We aimed to characterize and identify subclinical SSc-PHI using cardiovascular MRI to determine whether disease severity and serum biomarkers are associated with subclinical SSc-PHI. Methods: A total of 26 patients with SSc who had no history of cardiovascular disease or pulmonary hypertension underwent 3 T-enhanced cardiovascular MRI. Measurements included native T1, extracellular volume, advanced gadolinium enhancement, T2 mapping, and left ventricular volume function. Troponin T and N telencephalic natriuretic peptide precursors were also determined. Results: LGE was observed in 13 of 26 patients (50.0%), suggesting focal fibrosis, and T2 mapping was significantly higher in the dcSSc group than in the lcSSc group (P=0.009). Left ventricular volume and function were within the normal range in all patients, but final systolic left ventricular volume was significantly higher in dcSSc than in lcSSc (P=0.021). The modified Rodnan skin score (mRSS) was significantly higher in patients with LGE focal fibrosis (P=0.019). Logistic regression analysis confirmed the association between mRSS and LGE (OR=1.224, P=0.037). In multivariate analysis, T2 mapping was negatively correlated with disease course, and was correlated with dcSSc and fingertip ulcer (R2=0.711, P=0.018, P=0.013, P=0.030). Troponin T was correlated with T2 mapping (r=0.555, P=0.049). Conclusions: Subclinical SSc-PHI is characterized by diffuse and focal myocardial fibrosis, but preserves myocardial systolic function. Subclinical SSC-Phi is associated with TNT, SSc disease severity, and complex peripheral vascular disease. These data provide information for identifying individuals at risk of SSc-PHI.

Abstract
We retrospectively analyzed therapy efficacy and the adverse reactions of 10 patients suffering from systemic lupus erythematosus (SLE) with intestinal involvement treated with rituximab (RTX). Patients were hospitalized in the Department of Rheumatology and Immunology of the First Medical Center of PLA General Hospital from January 2015 to January 2023. Among the 10 patients, two were men and eight were women. The age of the cohort was (41.9±8.8) years. The age at disease onset was (28.8±9.2) years. The total course of the SLE diagnosis was(109.6±59.9) months. The course of the diagnosis of SLE with intestinal involvement was (89.3±50.2) months. The time from the appearance of intestinal symptoms to the diagnosis of SLE with intestinal involvement was 1.5 (1.0,8.0) months. The time from the diagnosis of SLE with intestinal involvement to RTX use was 13.0 (1.0,46.3) months. Follow-up duration after application of RTX treatment was (55.3±28.4) months. There were five cases of abdominal pain, four cases of abdominal distension, nine cases of diarrhea, three cases of nervous-system involvement, nine cases of lupus nephritis, and seven cases of serositis. All 10 patients underwent computed tomography and radiology of the abdomen. Eight patients had intestinal-wall edema, seven suffered intestinal dilation, four had target signs, three suffered congestion of mesenteric blood vessels, eight had increased mesenteric-fat density, and six had false intestinal obstruction. All 10 patients showed a low level of complement C3 (250-750 mg/L). Nine cases showed a low level of complement C4 (10-90 mg/L). The SLE disease activity index 2000 (SLEDAI-2K) at baseline in 10 patients was 20.5 (17.8, 30.0). After receiving RTX (0.5 g: day 1, day 14, or 375 mg/m2: day 1, day 14) induction treatment, the intestinal symptoms of 10 cases were relieved completely. Four patients had adverse reactions, of which three received a high-dose glucocorticoid combined with RTX treatment simultaneously. Adverse reactions manifested mainly as a reduced level of IgG and infection with herpes simplex virus in one case, reduced level of IgG and lung infection in one patient, lung infection in one case, and reduced IgG level in one patient. RTX may an efficacious treatment strategy for patients suffering from refractory SLE with intestinal involvement.

Abstract
BACKGROUND/AIM Matrix metalloproteinase-1 (MMP-1) expression has been documented as an influential contributor to the intricate milieu of allergic airway inflammation, tissue remodeling, and the exacerbation of asthma's severity. However, the genetic role underlying MMP-1 in the context of asthma has remained enigmatic, with its full implications yet to be unveiled. Considering this, our research was designed to investigate the association of MMP-1 -1607 rs1799750 and the propensity for asthma severity. PATIENTS AND METHODS As a case-control investigation, our study enrolled 198 individuals diagnosed with asthma and age- and sex-matched 453 non-asthmatic controls. The genotypes of MMP-1 rs1799750 were determined utilizing the polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The frequency distributions of 2G/2G, 1G/2G and 1G/1G genotypes at MMP-1 rs1799750 were 49, 42.9, and 8.1%, respectively, among the patients with asthma. This pattern was not different from that of controls (43.7, 46.8, and 9.5%, respectively) (p for trend=0.4486). The allelic frequency pertaining to the variant 1G allele within the asthma group was 29.5%, with a non-significant disparity compared to the 32.9% in the control group (p=0.2596). Noticeably, there was a positive association between MMP-1 rs1799750 2G/1G and 1G/1G genotypes with asthma severity (p=0.0060). CONCLUSION Our research indicated that the presence of MMP-1 rs1799750 1G allele might not be the sole arbiter of an individual's susceptibility to asthma, yet its potential to function as a discerning prognostic marker for the severity of asthma emerged as a noteworthy finding deserving attention and further exploration.

Abstract
Gemcitabine is frequently utilized to treat pancreatic cancer. The purpose of our study was to create a gemcitabine-resistant MIA-PaCa-2 pancreatic cancer cell line (MIA-GR100) and to evaluate the anti-pancreatic cancer efficacy of HMJ-38, a new quinazolinone analogue. Compared to their parental counterparts, MIA-PaCa-2, established MIA-GR100 cells were less sensitive to gemcitabine. MIA-GR100 cell viability was not affected by 10, 50 and 100 nM gemcitabine concentrations. HMJ-38 reduced MIA-GR100 cell growth and induced autophagy and apoptosis. When stained with monodansylcadaverine (MDC), acridine orange (AO), and terminal deoxynucleotide transferase dUTP nick end labeling (TUNEL), MIA-GR100 cells shrunk, punctured their membranes, and produced autophagy vacuoles and apoptotic bodies. Combining chloroquine (CQ) and 3-methyladenine (3-MA) with HMJ-38 dramatically reduced cell viability, indicating that autophagy function as a cytoprotective mechanism. MIA-GR100 cells treated with both z-VAD-FMK and HMJ-38 were much more viable than those treated with HMJ-38 alone. HMJ-38 promotes apoptosis in MIA-GR100 cells by activating caspases. Epidermal growth factor receptor (EGFR) is one of HMJ-38's principal targets, as determined via in silico target screening with network prediction. HMJ-38 also inhibited EGFR kinase activity and EGFR-associated signaling in MIA-GR100 cells. HMJ-38 may be an effective chemotherapeutic adjuvant for gemcitabine-resistant pancreatic cancer cells, in which it induces an antitumor response.

Abstract
Purpose Alopecia areata (AA) is one of the most prevalent autoimmune diseases affecting humans. Given that hair follicles are immune-privileged, autoimmunity can result in disfiguring hair loss. However, the genetic basis for AA in the Taiwanese population remains unknown. Materials and Methods A genome-wide association study was conducted using a cohort of 408 AA cases and 8167 controls. To link variants to gene relationships, we used 882 SNPs (P<1E-05) within 74 genes that were associated with AA group to build the biological networks by IPA software. HLA diplotypes and haplotypes were analyzed using Attribute Bagging (HIBAG)-R package and chi-square analysis. Results Seven single nucleotide polymorphisms (SNPs) including LINC02006 (rs531166736, rs187306735), APC (rs112800832_C_CAT), SRP19 (rs139948960, rs144784670), EGFLAM (rs16903975) and LDLRAD3 (rs79874564) were closely associated with the AA phenotype (P<5E-08). Examination of biological networks revealed that these genomic areas are associated with antigen presentation signaling, B cell and T cell development, Th1 and Th2 activation pathways, Notch signaling, crosstalk signaling between dendritic cells and natural killer cells, and phagosome maturation. Based on human leukocyte antigen (HLA) genotype analysis, four HLA genotypes (HLA-B*15:01-*40:01, HLA-DQA1*01:02-*03:03, HLA-DQA1*01:02, and HLA-DQB1*02:01) were found to be associated with AA (adjusted p-value<0.05). HLA-DQA1*01:02 is the most significantly related gene in the Taiwanese population (adjusted p-value = 2.09E-05). Conclusion This study successfully identified susceptibility loci associated with AA in the Taiwanese population. These findings not only shed light on the origins of AA within the Taiwanese context but also contribute to a comprehensive understanding of the genetic factors influencing AA susceptibility.

Abstract
Objective: To investigate the risk factors associated with the development of proximal junctional kyphosis (PJK) after posterior spinal fusion for in children with Lenke type 5 adolescent idiopathic scoliosis (AIS). Methods: It was a retrospective case-control study that included medical records of 98 children with Lenke type 5 AIS who underwent posterior orthopedic surgery under general anesthesia at the Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2013 to December 2018. There were 23 males and 75 females with a mean age of (14.5±2.2) years (10-18 years). Patients were divided into PJK and non-PJK groups according to whether the posterior junctional angle (PJA) was greater than 10° and increased for more than 10° from the preoperative period at the the last follow-up. Univariate analysis was used to analyze the correlation of general data of the children with occurrence of PJK after the operation. Multivariate logistic regression analysis was used to analyze the risk factors of postoperative PJK. Results: There were 35 cases in the PJK group and 63 cases in the non-PJK group. The PJK and non-PJK groups were followed up for (35.6±7.3) months and (36.4±7.5) months, respectively, and the difference was not statistically significant (P=0.637). There was no statistically significant difference between the two groups in general data such as gender, age, and body mass index (all P>0.05), while there were statistically significant differences between the two groups in upper instrumented vertebrea (UIV) location and junctional area posterior ligamentous complex (PLC) injury (all P<0.05). The results of univariate analysis showed that UIV location at T10-T12, junctional area PLC injury, preoperative coronal thoracic curve (TC), preoperative and final follow-up PJA, and preoperative and final follow-up pelvic incidence-lumbarlordosis (PI-LL) were correlated with postoperative PJK (OR=2.50, 5.37, 0.92, 1.12, 1.32, 1.06, 3.35, all P<0.05). Multifactorial logistic regression analysis showed that UIV located at T10-T12 (OR=2.346, 95%CI: 1.582-3.481, P=0.001), junctional area PLC injury (OR=5.112, 95%CI: 1.283-20.418, P=0.023) and last follow-up PI-LL (OR=1.826, 95%CI: 1.558-24.745, P=0.012) were risk factors for the occurrence of postoperative PJK in children with Lenke type 5 AIS. Conclusions: Postoperative UIV fixation to the thoracolumbar segment, PLC injury in the junctional area and excessive postoperative PI-LL in children with Lenke type 5 AIS may be the risk factors for the occurrence of PJK after the operation. It is suggested that avoidance of UIV selection to the thoracolumbar segment, intraoperative protection of the PLC located near the UIV and restoration of a good PI-LL relationship may reduce the incidence of PJK.

Abstract
Metformin has been used to treat cases of type 2 diabetes mellitus, and mounting studies have shown that metformin can act alone or in synergy with other anticancer agents to achieve anti-cancer efficacies on various types of tumors. However, the role of metformin in either inducing autophagy and cisplatin-resistance of human gastric cancer (GC) cells has never been examined. The study has established a cisplatin-resistant GC cell line and investigated the effects of metformin on inducing autophagy on it. The results demonstrated that treatment with metformin can concentration-dependently suppress the cell viability and cell confluence of cisplatin-resistant GC cells, while having no effects on human primary stomach epithelial cells (HPSEC). For the first time, we found that metformin can significantly increase the acidic vesicular organelles (AVO) level and decrease the acridine orange (AO) level spontaneously in the cisplatin-resistant GC cells. Thus, we further checked the other markers, Atg5, Atg12 and LC3-II, which showed that metformin indeed induced autophagy in the cisplatin-resistant GC cells. In addition, treatment of 3-Methyladenine (3-MA) can significantly rescue the metformin-induced autophagy. At the same time, metformin can induce the alterations of apoptosis-associated signal molecules, such as caspase-3 and caspase-7 activities. Overall, the pilot study provided evidence for metformin induced autophagy in addition to apoptosis, making it as an effective anticancer drug for the therapy of cisplatin-resistant GC. Killing the cisplatin-resistant GC cells with non-toxic metformin via both autophagy and apoptosis might extend its usefulness in our fighting with chemo-resistance of gastric cancer cells.

Abstract
BACKGROUND/AIM Non-alcoholic fatty liver disease is a major cause of liver-related morbidity and mortality. Metformin is a widely used medication and may have additional benefits beyond glycemic control. Liraglutide, a novel treatment for diabetes and obesity, also has beneficial effects on non-alcoholic steatohepatitis (NASH). Metformin and liraglutide have both benefited NASH treatment. However, no study has reported the effects of combination therapy with liraglutide and metformin on NASH. MATERIALS AND METHODS We investigated the in vivo effects of metformin and liraglutide on NASH in a methionine/choline-deficient (MCD) diet-fed C57BL/6JNarl mouse model. Serum triglyceride, alanine aminotransferase and alanine aminotransferase levels were documented. Histological analysis was performed according to the NASH activity grade. RESULTS After treatment with liraglutide and metformin, body weight loss improved, and the liver/body weight ratio decreased. The metabolic effects and liver injury improved. Liraglutide and metformin alleviated MCD-induced hepatic steatosis and injury. Histological analysis revealed that NASH activity was reduced. CONCLUSION Our results provide evidence for the anti-NASH activity of liraglutide in combination with metformin. Liraglutide with metformin may offer the potential for a disease-modifying intervention for NASH.

Abstract
Background Cisplatin, the first-line drug for chemotherapy, often has limited treatment efficacy because of resistance and cancer recurrence mechanisms. Tetrandrine is a unique secondary metabolite of Stephania tetrandra. As a traditional Chinese medicine agent, tetrandrine has been reported to have antioxidant, anti-inflammatory, antitumor, and antiangiogenesis activities and has been shown to inhibit the proliferation and angiogenesis of colorectal, lung, and breast cancer cells; potential mechanisms underlying its activities include the promotion of tumor cell apoptosis, promotion of cell cycle arrest, and intensification of reactive oxygen species (ROS) production. Objectives The main treatments for oral cancer are chemotherapy, surgery, and radiotherapy; these treatments are often used in combination. Cancer cells easily develop cisplatin resistance; therefore, we investigated tetrandrine’s potential as a therapy for overcoming resistance to oral cancer drugs. Materials and Methods We used the cisplatin-resistant oral cancer CAR cell line (CAL27) as a research objected and applied inhibitor treatment to clarify the role of tetrandrine in cell death and mitochondrial dysfunction. Results Tetrandrine could effectively inhibit CAR cell proliferation and induce apoptosis, with a corresponding increase in ROS production in mitochondria. Moreover, tetrandrine increased caspase-9 and caspase-3 activity in CAR cells and induced apoptotic mRNA, caspase-3/-9, AIF, and Endo G overexpression. Our results indicate that tetrandrine induces apoptosis in CAR cells through a mitochondrial-dependent signaling pathway.

Abstract
The study aimed to analyze the efficacy and safety of rituximab in the treatment of 23 cases of lupus nephritis and explore the prospect of half-dose rituximab in lupus nephritis treatment. Twenty-three patients with lupus nephritis hospitalized in the Department of Rheumatology and Immunology at the First Medical Center of the PLA General Hospital from May 2013 to December 2021 were selected. Eighteen patients received rituximab 375 mg/m2 on the first and 14th days, 5 patients received 500 mg of rituximab on the first and 14th days, and rituximab was used as needed 6 months later. Methylprednisolone (80-120 mg) was given together with rituximab. Afterward, 1 mg/kg prednisone was used for 4 weeks, which was progressively tapered to maintenance doses or discontinued. B lymphocyte level, renal function, 24-h urine protein level, and systemic lupus erythematosus (SLE) disease activity index 2000 (SLEDAI2K) score before and after treatment were recorded. The efficacy and adverse reactions were analyzed. The results showed that 11 patients suffered from renal insufficiency [creatinine (162.7±58.6) μmol/L ] at baseline, while the creatinine level of 9 patients returned to normal 12 months after the treatment [ (66.3±10.1)μmol/L ]. Normal renal function of the other 12 patients was maintained during treatment. After 12 months, the 24-h urine protein level decreased from 4.00 (2.00,6.80) g in the baseline period to 0.10 (0.08,0.40) g. SLEDAI2K score decreased from 22 (18,26) in the baseline period to 3 (0,6) 12 months after the treatment. The B lymphocyte level reached 0.00 (0.00,0.01)% at 3 months. Of 23 patients, 13 patients achieved complete remission, and 7 patients achieved partial remission after 6 months of rituximab treatment. Five patients experienced adverse reactions related to rituximab, including 1 case of transfusion reaction, 1 case of perioral herpes with pulmonary infection, and 3 cases of decreased IgG levels. Therefore, rituximab regimen used in this study can be an effective treatment strategy for lupus nephritis.

Abstract
Objective: To investigate the predictive value of SYNTAX-Ⅱ score on long term prognosis of patients diagnosed with chronic total occlusion (CTO) and received percutaneous coronary intervention (PCI). Methods: Patients undergoing CTO-PCI in Fuwai hospital from January 2010 to December 2013 were enrolled in this retrospective analysis. The SYNTAX-Ⅱ score of the patients was calculated. According to SYNTAX-Ⅱ score tertiles, patients were stratified as follows: SYNTAX-Ⅱ≤20, 20<SYNTAX-Ⅱ≤27, SYNTAX-Ⅱ>27. Primary endpoint was major adverse cardiac events (MACCE), including all-cause death, myocardial infarction, stroke and any revascularization. Secondary endpoints included stent thrombosis, heart failure and target lesion failure (TLF). Patients were followed up by outpatient visit or telephone call at 1 month, 6 months and 1 year after PCI, and annually up to 5 years. Multivariate Cox regression model was used to analyze the independent risk factors of all-cause death in patients undergoing CTO-PCI. The predictive value of SYNTAX score with SYNTAX-Ⅱ score for all-cause death was evaluated by the receiver operating characteristic (ROC) curve and the area under the curve (AUC). Results: A total of 2 391 patients with CTO and received PCI were enrolled in this study. The mean age was (57.0±10.5) years, 1 994 (83.40%) patients were male. There were 802 patients in lower tertile group (SYNTAX-Ⅱ≤20), 798 patients in intermediate group (20<SYNTAX-Ⅱ≤27) and 791 patients in upper tertile group (SYNTAX-Ⅱ>27). At the end of 5-year follow-up, the loss to follow-up rate of the three groups was 9.10%(73/802), 10.78%(86/798)and 8.85%(70/791), respectively. The rate of all-cause mortality (1.78% (13/729) vs. 3.65% (26/712) vs. 9.02% (65/721), P<0.001), cardiac death (1.37% (10/729) vs. 2.11% (15/712) vs. 4.85% (35/721), P<0.001), target vessel myocardial infarctions (4.25% (31/729) vs. 4.49% (32/712) vs. 7.07% (51/721), P=0.03), probable stent thrombosis (1.51% (11/729) vs. 2.81% (20/712) vs. 3.61% (26/721), P=0.04) and heart failure (1.78% (13/729) vs. 1.97% (14/712) vs. 5.41% (39/721), P<0.001) increased in proportion to increasing SYNTAX-Ⅱ score (all P<0.05). Multivariable Cox regression analysis indicated that female (HR=2.05, 95%CI 1.12-3.73, P=0.01), left ventricular ejection fraction (HR=0.97, 95%CI 0.95-1.00, P=0.05) and SYNTAX-Ⅱ score (HR=1.07, 95%CI 1.02-1.11,P=0.01) were independent predictors for all-cause mortality in patients undergoing CTO-PCI. The predicted value of the SYNTAX-Ⅱ score for all-cause death was significantly higher than the SYNTAX score (AUC 0.71 vs. 0.60, P=0.003). Conclusion: For CTO patients who underwent percutaneous coronary intervention, SYNTAX-Ⅱ score is an independent predictor for 5-year all-cause death, and SYNTAX-Ⅱ serves as an important predictor for all-cause death in these patients.

Abstract
Social media use to discuss ENDS among youth in distressed areas is understudied. Nearly 1 in 3 and 1 in 8 of youth were ever and current ENDS users, respectively. Nearly 1 in 5 of the youth reported using social media to talk about ENDS. Social media increased current and ever ENDS use by 4 and 3 times, respectively. Social media engagement may lead to ENDS uptake among youth in distressed areas.
Electronic nicotine delivery systems (ENDS) are the most used tobacco products among middle and high schoolers in the United States (U.S.). Familial relations and access play a major role in uptake among adolescents; yet the role of social media in this phenomenon in the context of communities impacted by tobacco-related health disparities is understudied. In Spring 2019, data were collected from adolescents in 8th and 9th grades in a school located in a rural distressed county in Tennessee to assess social media’s role in ENDS uptake. Descriptive and multivariable statistical analyses were performed to delineate factors associated with ENDS use. Of a total of 399 respondents, 12.5 % reported current ENDS use and 22.1 % indicated having ever discussed ENDS on social media. Closed messaging platforms (Snapchat) and video platforms (Facebook/Instagram/You Tube) were the most reported form of social media used (8.31 % and 8.31 % respectively). Social media use was positively associated with both ever ENDS use (odds ratio [OR] = 2.9) and current ENDS use (OR = 3.98). Parental advice against ENDS use was positively associated with ever ENDS use. In conclusion, social media use was positively associated with both ever and current ENDS use, and Snapchat was the most popular platform among this population of students. The results indicate that youth social media engagement may lead to exposure that can influence ENDS uptake. Future studies are needed to further examine these associations among distressed communities.

Abstract
BACKGROUND/AIM Triple negative breast cancer (TNBC) is one of the most challenging breast cancer types. Interleukin-8 (IL-8) is a pro-tumorigenic cytokine, promoting tumor proliferation and migration. This study aimed to examine the contribution of IL-8 rs4073 genotypes to breast cancer risk and provide a summary of related literature. MATERIALS AND METHODS IL-8 genotypic profiles were determined among 1,232 breast cancer cases and 1,232 controls via polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The IL-8 rs4073 AT and AA genotypes had significantly lower prevalence in the case group compared to control group. Allelic frequency analysis showed that individuals carrying the A allele have relatively decreased risk for breast cancer. The stratification analysis showed that IL-8 rs4073 genotypes were protective markers for those with younger (≤55) age. CONCLUSION IL-8 rs4073 A allele is a novel predictor for breast cancer, especially TNBC.

Abstract
OBJECTIVES MTH-3, a curcumin derivative, exhibits improved water solubility. This study aims to elucidate the mechanisms underlying the anticancer effects of MTH-3 on human oral squamous cell carcinoma CAL27 cisplatin-resistant (CAR) cells. METHODS To evaluate the biological functions of MTH-3 in CAR cells, flow cytometry, staining, and western blot analyses were used. KEY FINDINGS MTH-3 reduced CAR cell viability and significantly induced autophagy in the presence of 10 and 20 μM MTH-3. Transcription factor EB was identified as the potential target of MTH-3. Autophagy-related proteins were upregulated after 24 h of MTH-3 incubation. MTH-3 treatment increased caspase-3 and caspase-9 enzyme activities. Mitochondrial membrane potential was decreased after MTH-3 treatment. MTH-3 triggered the intrinsic apoptotic pathway. CONCLUSIONS MTH-3 induces autophagy and apoptosis of CAR cells via TFEB. MTH-3 might be an effective pharmacological agent for treating oral cancer cells.

Abstract
Melanoma is a malignant tumor with aggressive behavior. Vemurafenib, a BRAF inhibitor, is clinically used in melanoma, but resistance to melanoma cytotoxic therapies is associated with BRAF mutations. Curcumin can effectively inhibit numerous types of cancers. However, there are no reports regarding the correlation between curcumin and vemurafenib-resistant melanoma cells. In this study, vemurafenib-resistant A375.S2 (A375.S2/VR) cells were established, and the functional mechanism of the epidermal growth factor receptor (EGFR), serine-threonine kinase (AKT), and the extracellular signal-regulated kinase (ERK) signaling induced by curcumin was investigated in A375.S2/VR cells in vitro. Our results indicated that A375.S2/VR cells had a higher IC50 concentration of vemurafenib than the parental A375.S2 cells. Moreover, curcumin reduced the viability and confluence of A375.S2/VR cells. Curcumin triggered apoptosis via reactive oxygen species (ROS) production, disruption of mitochondrial membrane potential (ΔΨm), and intrinsic signaling (caspase-9/-3-dependent) pathways in A375.S2/VR cells. Curcumin-induced apoptosis was also mediated by the EGFR signaling pathway. Combination treatment with curcumin and gefitinib (an EGFR inhibitor) synergistically potentiated the inhibitory effect of cell viability in A375.S2/VR cells. The present study provides new insights into the therapy of vemurafenib-resistant melanoma and suggests that curcumin might be an encouraging therapeutic candidate for its drug-resistant treatment.

Abstract
The modern surgical treatment of cervical degenerative disc disease can be traced back to the advent of anterior cervical decompression and fusion.With the emergence of fusion-related complications,different scholars have promoted the gradual transformation of cervical degenerative disc diseases from "fusion fixation" to "non-fusion reconstruction" through in-depth fusion with materials science,engineering mechanics and other disciplines.The innovation of this treatment concept is consistent with the original intention of "structural remodeling,functional reconstruction,maximum repair and reconstruction of the morphology and function of skeletal muscle system" in orthopedic bionic treatment,which is essentially in line with the "bionic alternative therapy" in orthopedic bionic therapy.This paper focuses on the surgical treatment of cervical degenerative disc diseases,reviews the development history of artificial cervical disc replacement,analyzes the evolution from orthopedic biomimetic therapy,and explores a new direction for the design of artificial cervical disc prostheses and the treatment of cervical degenerative disc diseases in the future.

Abstract
BACKGROUND/AIM Natural skin whiteners have been investigated for centuries. The development of preparations that safely achieve whitening of hyper-pigmented skin lesions is a challenge for the cosmetics industry. Furthermore, promoting rapid wound healing and minimizing inflammation in injured skin are key to prevent from abnormal pigmentation in scar tissue. Natural products, including the fungus Tremella fuciformis (TF), are attracting attention as potential sources of lead compounds for these applications. MATERIALS AND METHODS We investigated the in vitro effects of TF on melanogenesis in murine B16F10 cells. Melanin and tyrosinase levels were measured after treatment with TF. Wound healing in human keratinocytes (HaCaT) and fibroblasts (Detroit 551) was also determined via cell migration assay prior to TF exposure. RESULTS TF significantly decreased melanin content and tyrosinase expression in a concentration-dependent manner in B16F10 cells. Furthermore, TF promoted wound healing in human HaCaT keratinocytes and Detroit 551 fibroblasts. CONCLUSION TF proved effectively on inhibiting melanogenesis and promoting wound healing in vitro, demonstrating its potential as a novel skin-whitening agent. However, further clinical studies of safety and efficacy are required.

Abstract
BACKGROUND/AIM Gadolinium has been reported to cause liver lobular necrosis and nephrogenic systemic fibrosis. However, its toxicity to the skin remains unknown. This study aimed to investigate the effect of a high dose of gadolinium-based contrast agent gadodiamide on the human keratinocyte HaCaT cell line. MATERIALS AND METHODS Cell viability was assessed using MTT assay, and autophagy was assessed using acridine orange and LysoTracker Red staining. Western blotting was performed to verify the changes in Bcl2 and Bax levels. RESULTS The viability of HaCaT cells was significantly suppressed after gadodiamide treatment. Interestingly, gadodiamide caused autophagic vacuoles, whereas the autophagy inhibitors 3-methyladenine and chloroquine significantly alleviated autophagic cell death. Simultaneously, gadodiamide induced apoptosis, which was reduced by caspase inhibitors. Gadodiamide also inhibited Bcl-2 expression and promoted Bax expression. CONCLUSION Gadodiamide induced both autophagy and apoptosis in HaCaT cells. Physicians should carefully assess the gadodiamide dosage used clinically.

Abstract
BACKGROUND/AIM Helicobacter pylori, a gram-negative bacterium, causes chronic stomach diseases in humans. Heat shock proteins (HSPs) are involved in cell integrity, cell growth, and gastric mucosa colonization by H. pylori. This study aimed to investigate HSP expression levels in H. pylori-infected gastric adenocarcinoma AGS cells. MATERIALS AND METHODS We determined protein expression levels using iTRAQ proteomics analysis. We analyzed the possible network interactions for H. pylori targets in AGS cells using the Ingenuity Pathway Analysis (IPA) software. RESULTS H. pylori-infected AGS cells potentially targeted EIF2 and BAG2 signaling pathways to regulate cell physiology. In addition, after 3, 6, and 12 h of infection, western blotting revealed significantly decreased HSP70 and HSP105 expression. CONCLUSION H. pylori decreases HSPs in AGS gastric adenocarcinoma cells, and this is associated with the regulation of EIF2 and BAG2 signaling pathways.

Abstract
Negative impacts of COVID-19 on human health and economic and social activities urge scientists to develop effective treatments. Baicalin is a natural flavonoid, extracted from a traditional medicinal plant, previously reported with anti-inflammatory activity. In this study, we used pharmacophore fitting and molecular docking to screen and determine docking patterns and the binding affinity of baicalin on 3 major targets of SARS-CoV-2 (3-chymotrypsin-like cysteine protease [3CLpro], papain-like protease [PLpro], and RNA-dependent RNA polymerase). The obtained data revealed that baicalin has high pharmacophore fitting on 3CLpro and predicted good binding affinity on PLpro. Moreover, using the enzymatic assay, we examined the inhibitory effect of baicalin in vitro on the screened enzymes. Baicalin also exhibits inhibitory effect on these proteases in vitro. Additionally, we performed pharmacophore-based screening of baicalin on human targets and conducted pathway analysis to explore the potential cytoprotective effects of baicalin in the host cell that may be beneficial for COVID-19 treatment. The result suggested that baicalin has multiple targets in human cell that may induce multiple pharmacological effects. The result of pathway analysis implied that these targets may be associated with baicalin-induced bioactivities that are involved with signals of pro-inflammation factors, such as cytokine and chemokine. Taken together with supportive data from the literature, the bioactivities of bailalin may be beneficial for COVID-19 treatment by reducing cytokine-induced acute inflammation. In conclusion, baicalin is potentially a good candidate for developing new therapeutic to treat COVID-19.

Abstract
BACKGROUND/AIM The use of iodinated contrast media may impair renal function. However, no report has addressed the nephrotoxicity of high doses of iodinated contrast media in normal kidney cells and its associated molecular mechanisms. MATERIALS AND METHODS Cell proliferation was assessed using the MTT assay. Cell death was evaluated through examining the morphological changes and TUNEL assay. Autophagy was detected through acridine orange staining and lysotracker staining. Reactive oxygen species production and AKT kinase activity were examined. RESULTS Iopromide induced cell death and triggered apoptosis and autophagy in HEK 293 cells. Cell viability was significantly restored in the presence of a pan-caspase inhibitor or a ROS scavenger, N-acetyl-L-cysteine. AKT kinase activity was found to be reduced in iopromide-treated HEK 293 cells. CONCLUSION High concentrations of iopromide induce cell damage, apoptosis, and autophagy through down-regulating AKT and ROS-activated cellular stress pathways in HEK 293 cells.

Abstract
BACKGROUND/AIM At present, there are no effective drugs for the treatment of insulin resistance. MTH-3, a curcumin derivative, exerts potent anti-cancer effects. The aim of the present study was to explore whether MTH-3 is capable of regulating palmitic acid (PA)-induced insulin resistance in C2C12 cells. MATERIALS AND METHODS Cell viability was examined using the MTT assay. C2C12 cells were treated with PA and evaluated for the production of oil droplets using an Oil Red O assay. Glucose uptake was analysed by the 2-NBDG assay. RESULTS Treatment of cells with up to 500 μM PA for 24 h or with 5 or 10 μM MTH-3 had no effect on cell viability. PA induced production of oil droplets in C2C12 cells. After adding MTH-3, the quantity of oil droplets decreased significantly and glucose uptake recovered. CONCLUSION MTH-3 may become an efficient drug for the treatment of insulin resistance and associated diseases.

Abstract
Due to the significantly negative impact of the coronavirus (CoV) disease (COVID-19) pandemic on the health of the community and the economy, it remains urgent and necessary to develop a safe and effective treatment method for COVID-19. Huang-Lian-Shang-Qing-Wan (HLSQW) is a herbal formula of traditional Chinese medicine (TCM) that has been applied extensively for treating “wind-heat-associated” symptoms in the upper parts of the body. The objective of the present in silico study was to investigate the potential effects of HLSQW in the context of severe acute respiratory syndrome (SARS)-CoV-2 infection. We analyzed the possible interactions between bioactive compounds within HLSQW on targets that may confer antiviral activity using network pharmacology and pharmacophore-based screening. HLSQW was found to potentially target a number of pathways and the expression of various genes to regulate cell physiology and, consequently, the anti-viral effects against SARS-CoV-2. Bioactive compounds contained within HLSQW may exert combined effects to reduce the production of proinflammatory factors, which may trigger the “cytokine storm” in patients with severe COVID-19. Results from molecular modeling suggested that the bioactive HLSQW components puerarin, baicalin, and daidzin exhibit high binding affinity to the active site of 3-chymotrypsin-like cysteine protease (3CLpro) to form stable ligand-protein complexes, thereby suppressing SARS-CoV-2 replication. In addition, our results also demonstrated protective effects of the HLSQW extract against cell injury induced by the proinflammatory cytokines tumor necrosis factor-α, interleukin (IL)-1β, and IL-6, against reactive oxygen species production and nuclear factor-κB activity in normal human lung cells in vitro. To conclude, HLSQW is a potential TCM remedy that warrants further study with the aim of developing an effective treatment for COVID-19 in the future.

Abstract
BACKGROUND/AIM This study investigated whether genetic variations in cyclin D1 (CCND1) are associated with susceptibility to childhood acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS A total of 266 childhood ALL cases and 266 healthy controls were genotyped for CCND1 rs9344 and rs678653. RESULTS There was a significant difference in the genotypic distribution of rs9344 between childhood ALL patients and healthy controls (p=0.0077). Compared to the AA genotype, AG and GG genotypes were associated with significantly decreased risks of childhood ALL with odds ratio (OR) of 0.65 [95% confidence interval (CI)=0.44-0.94, p=0.0234] and 0.45 (95%CI=0.26-0.78, p=0.0040), respectively. Supporting this, allelic frequency distributions between childhood ALL patients and controls was significantly different (OR=0.68, 95%CI=0.53-0.88, p=0.0025). There was no significant difference in the genotypic and allelic distributions of rs678653 between cases and controls. CONCLUSION CCND1 rs9344, but not rs678653, may serve as a predictive marker of susceptibility for childhood ALL.

Abstract
Objective: To evaluate the auditory efficacy and subjective satisfaction of adhesive bone conduction hearing aid in children with unilateral congenital aural atresia (UCAA). Methods: Ten subjects (5 males and 5 females) diagnosed with UCAA with an average age of 8.3 years old (ranged from 5 to 15) were included in Beijing Tongren Hospital, Capital Medical University from January to August 2019. The free sound field hearing threshold, word recognition score in quiet, speech reception threshold in noise and sound localization ability (results were measured by RMS error) tests were performed in unaided and aided situation, respectively. Subjective satisfaction questionnaires were also distributed to subjects. Paired t test and Wilcoxon signed rank test were used as statistical analysis methods. Results: The average hearing threshold in aided condition was improved by (21.9±4.4) dB (t=15.8,P<0.05). Speech recognition abilities were generally improved both under quiet and noise (P<0.05);however, when the binaural summation, squelch and head shadow effects were analyzed respectively, the binaural squelch effect was not statistically improved (P>0.05), while the other effects were improved in aided condition (P<0.05). In sound localization test, there was no significant difference of the RMS error value between the unaided and aided situation (P>0.05). The subjects got high satisfaction rates in three subjective questionnaires. Conclusion: The adhesive bone conduction hearing aid can provide significant audiological benefit for children with UCAA as well as raising the quality of their life.

Abstract
BACKGROUND/AIM Breast cancer incidence is highest among women worldwide, and practical markers for personalized therapeutic strategies are few. Interleukin-12 (IL-12) is a cytokine that is reported to be significantly lower in healthy controls than breast cancer cases, however, its genotypic contribution to carcinogenesis has never been revealed in breast cancer. We examined whether IL-12A rs568408 and rs2243115 genotypes contribute to elevated breast cancer risk and summarized related literature among other cancers. MATERIALS AND METHODS IL-12A genotypic profiles were determined among 1,232 breast cancer cases and 1,232 healthy controls via polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The variant genotypes of IL-12A rs568408 and rs2243115 were not found to be significantly associated with elevated breast cancer risk (both p>0.05). CONCLUSION IL-12A rs568408 and rs2243115 genotypes may not serve as good predictors of breast cancer risk.

Abstract
BACKGROUND The goal of this study was to investigate the prognostic factors for locoregional recurrence and metastasis in patients with cutaneous melanoma (CM) who underwent surgery, especially in the acral lentiginous melanoma (ALM) subtype. METHODS This study was a retrospective review of patients who underwent surgery for CM at Taipei Veterans General Hospital between 2000 and 2018. We investigated the risk factors for locoregional and distant metastases. The association between clinicopathological factors and locoregional recurrence and distant metastasis of the CM and ALM subtypes was analyzed. In addition, the outcomes between the ALM and non-ALM groups were compared. RESULTS A total of 161 patients were included in the analysis. The most common histological subtype was ALM. The overall locoregional recurrence rate of CM was 13.0% and the distant metastasis rate was 42.9%, whereas that of the ALM subtype was 12.5% and 45.5%, respectively. In patients with CM, male sex, tumor with lymphovascular invasion, and positive lymph node status were the prognostic factors for both locoregional recurrence and distant metastasis. Among the patients with ALM, positive lymph node status was significantly associated with both locoregional recurrence and distant metastasis. CONCLUSION In this cohort, factors influencing locoregional recurrence and distant metastasis were similar between the ALM and non-ALM groups. The above-recommended surgical margin did not show any benefit in either the CM or the ALM subtype. ALM can be handled using the same surgical strategy as CM in the Asian population.

Abstract
Introduction Patients with colorectal cancer (CRC) often develop distant metastases, which significantly reduces the 5-year survival rate. Epithelial-mesenchymal transition (EMT) is a crucial process for the invasion and metastasis of cancer cells. Tetrandrine has been reported to inhibit the viability and EMT of CRC cells; however, to the best of our knowledge, the molecular mechanism remains undetermined. Methods The MTT assay was used to determine HCT116 cell viability. Wound healing and Transwell assays were used to determine that cell migration and invasion, respectively. Western blotting analysis was performed to detect the expression of migration-related genes. Four different lengths of the E-cadherin gene promoter were constructed and cloned into pGL3 reporter plasmids to evaluate E-cadherin gene promoter activity. Results The results of the MTT assay revealed that tetrandrine inhibited HCT116 cell viability, with an IC50 value of 7.2 μM following 24 h of treatment. Tetrandrine inhibited IL-6-induced cell migration and invasion, respectively. Tetrandrine regulates the expression of migration-related genes in IL-6-stimulated HCT116 cells. Tetrandrine significantly downregulated the expression and enzyme activity of MMP-2 in IL-6-stimulated HCT116 cells. In addition, tetrandrine restored E-cadherin gene promoter activity. Conclusion The findings of the present study suggested that tetrandrine may inhibit EMT in IL-6-stimulated HCT116 cells; therefore, it may represent a potential drug for CRC.

Abstract
BACKGROUND/AIM Magnetic resonance imaging (MRI) is a technique for evaluating patients with primary and metastatic tumors. The contrast agents improve the diagnostic accuracy of MRI. Large quantities of a contrast agent must be administrated into the patient to obtain useful images, which leads to cell injury. Gadolinium has been reported to cause central lobular necrosis of the liver and nephrogenic systemic fibrosis. However, the toxicity caused on brain tissue is uncertain. MATERIALS AND METHODS This study mainly aimed on the in vitro study of high concentration (2 and 5-fold of normal concentration) gadolinium-based contrast agents (GBCAs), gadodiamide (Omniscan®), on normal brain glial SVG P12 cells. MTT assay, DAPI staining, immunofluorescent staining, LysoTracker Red staining, and western blotting analysis were applied on the cells. RESULTS The viability of gadodiamide (1.3, 2.6, 5.2, 13 and 26 mM)-treated SVG P12 cells was significantly reduced after 24 h of incubation. Gadodiamide caused significant autophagic flux at 2.6, 5.2 and 13.0 mM as seen by acridine orange (AO) staining, LC-3-GFP and LysoTracker Red staining. The expression levels of autophagy-related proteins such as beclin-1, ATG-5, ATG-14 and LC-3 II were up-regulated after 24 h of gadodiamide incubation. Autophagy inhibitors including 3-methyladenine (3-MA), chloroquine (CQ) and bafilomycin A1 (Baf) significantly alleviated the autophagic cell death effect of gadodiamide on normal brain glial SVG P12 cells. Gadodiamide induced significant apoptotic effects at 5.2 mM and 13.0 mM as seen by DAPI staining and the pan-caspase inhibitor significantly alleviated the apoptotic effect. Gadodiamide at 5.2 mM and 13.0 mM inhibited antiapoptotic protein expression levels of Bcl-2 and Bcl-XL, while promoted pro-apoptotic protein expression levels of Bax, BAD, cytochrome c, Apaf-1, cleaved-caspase-9 and cleaved-caspase-3. CONCLUSION Normal brain glial SVG P12 cells treated with high concentrations of gadodiamide can undergo autophagy and apoptosis.

Objective: To study the effect of the inhibitor of Notch signaling pathway-γ-secretase inhibitor DAPT on the ultrastructures of middle ear in the ovalbumin (OVA)-mediated allergic OME in vivo. Methods: Male Sprague-Dawley (SD) rats, weighing 250-300 g, were completely and randomly divided into three groups (5 rats, 10 ears in each group):(1)Control group(2)OME group(3)OME+DAPT group. Rats in the OME group underwent systemic and local sensitization by intraperitoneal and intratympanic injection of ovalbumin to make the model of OVA-induced OME. Rats in the control group were sensitized with PBS. On the basis of establishing the OME model, OME+DAPT group were intraperitoneal injected with DAPT (10 mg/kg) for seven consecutive days and were administered before intratympanic injection of ovalbumin. After the model was successfully established, endoscopy,H&E staining and scanning electron microscopy were used to study the histology and mucous-ciliary ultrastructures of the non-ciliated and ciliated mucosa in the middle ear of each group. One-way ANOVA and Tukey methods were used for statistical analysis. Results: H&E staining showed that the three groups had statistically significant differences in submucosal thickness both in non-ciliated and ciliated regions (non-ciliated area:(6.83±1.47)μm, (38.58±9.57)μm, (32.17±11.89)μm, respectively. F=107.9;cilia area:(26.69±3.22)μm, (30.41±6.75)μm, (26.76±4.06)μm, respectively. F=5.62,both P<0.01). The thickness of the submucosa in the non-ciliated area and the cilia area of the OME group were significantly thicker than that of control group (F=42.08 and 4.40,both P<0.05); the thickness of the non-ciliated area and the ciliated area in OME+DAPT group were reduced compared to OME group(F=1.55 and 2.77,both P<0.05). Scanning electron microscopy showed that the array of cilia on the middle ear mucosa was disorderly arranged and inversed, this phenomenon was relieved in the OME+DAPT group. The number of goblet cells in the control group, OME group, and OME+DAPT group were 9.87±1.92; 15.67±5.77; 10.33±1.99 respectively and the difference between them was statistically significant (F=11.43, P<0.01). The number of goblet cells in the OME group were significantly higher than those in the control group (F=9.00,P<0.01) and the number of goblet cells in the OME+DAPT group were decreased compared to those of OME group (F=8.41, P<0.01). Conclusions: The study demonstrates the pathological changes of the ultrastructure in middle ear in OVA-induced OME and the effect of the γ-secretase inhibitor on it. In OME group, the cilia are disorderly arranged and inversed, the number of goblet cell is increased and they are swelled which suggest the hypersecretion of the mucus. DAPT can regulate OVA-induced allergic inflammation and relieve pathological changes of ultrastructure in middle ear mucociliary transport system through alleviating submucosal inflammation, reducing the hypersecretion of goblet cell and the morphological damage of cilia through the Notch signaling pathway.

Abstract
Triple‑negative breast cancer (TNBC) behaves aggressively in the invasive and metastatic states. Our research group recently developed a novel curcumin derivative, (1E,3Z,6E)-3-hydroxy-5-oxohepta-1,3,6-triene-1,7-diyl)bis(2‑methoxy-4,1‑phenylene)bis(3-hydroxy2-hydroxymethyl)-2‑methyl propanoate (MTH‑3), and previous studies showed that MTH‑3 inhibits TNBC proliferation and induces apoptosis in vitro and in vivo with a superior bioavailability and absorption than curcumin. In the present study, the effects of MTH‑3 on TNBC cell invasion were examined using various assays and gelatin zymography, and western blot analysis. Treatment with MTH‑3 inhibited MDA‑MB‑231 cell invasion and migration, as shown by Transwell assay, 3D spheroid invasion assay, and wound healing assay. The results of the gelatin zymography experiments revealed that MTH‑3 decreased matrix metalloproteinase‑9 activity. The potential signaling pathways were revealed by next‑generation sequencing analysis, antibody microarray analysis and western blot analysis. In conclusion, the results of the present study show that, MTH‑3 inhibited tumor cell invasion through the MAPK/ERK/AKT signaling pathway and cell cycle regulatory cascade, providing significant information about the potential molecular mechanisms of the effects of MTH‑3 on TNBC.

Abstract
Dracorhodin can be isolated from the exudates of the fruit of Daemonorops draco. Previous studies suggested that dracorhodin perchlorate can promote fibroblast proliferation and enhance angiogenesis during wound healing. In the present study, the potential bioactivity of dracorhodin perchlorate in human HaCaT keratinocytes, were investigated in vitro, with specific focus on HaCaT wound healing. The results of in vitro scratch assay demonstrated the progressive closure of the wound after treatment with dracorhodin perchlorate in a time-dependent manner. An MTT assay and propidium iodide exclusion detected using flow cytometry were used to detect cell viability of HaCaT cells. Potential signaling pathways underlying the effects mediated by dracorhodin perchlorate in HaCaT cells were clarified by western blot analysis and kinase activity assays. Dracorhodin perchlorate significantly increased the protein expression levels of β-catenin and activation of AKT, ERK and p38 in HaCaT cells. In addition, dracorhodin perchlorate did not induce HaCaT cell proliferation but promoted cell migration. Other mechanisms may yet be involved in the dracorhodin perchlorate-induced wound healing process of human keratinocytes. In summary, dracorhodin perchlorate may serve to be a potential molecularly-targeted phytochemical that can improve skin wound healing.

Abstract
Cisplatin resistance is a major clinical problem in the clinical management of oral squamous cell carcinoma (OSCC) patients. Resveratrol is a natural phytoestrogen with antitumor activities. Whether resveratrol can overcome cisplatin resistance and prevent metastasis in OSCC cells is not known. In this study, we first examined the anti-metastatic capacity of resveratrol and then explored the underlying mechanisms using a cisplatin-resistant human OSCC cell line (CAR). The results demonstrated that at a non-toxic dose range (25 to 75 µM), 24-hr treatment of resveratrol was able to suppress the migration and invasion capacities of CAR cells dose dependently. Interestingly, 50 µM resveratrol treatment could significantly down-regulate the expression of the phosphorylated forms of ERK and p-38, in addition to those of MMP-2 and MMP-9. At the same time, the expression levels of phosphorylated ERK together with those unphosphorylated forms of ERK, p38, and JNK were all insignificantly altered. In conclusion, the signaling cascade for resveratrol's suppression of cisplatin-resistant human oral cancer CAR cells was revealed and summarized. Also the rapid effectiveness in suppressing metastatic behaviors of drug-resistant oral cancer cells of non-toxic resveratrol might extend its application to the drug-resistant oral cancer treatment in the near future. PRACTICAL APPLICATIONS: Based on the evidence we provided in the study, we have proposed a model recording the possible pathway for resveratrol inhibiting the metastasis of cisplatin-resistant oral cancer cells. We suppose this signaling pathway may work in other cancer cell lines, and can be helpful in full understanding of the drug-resistance.

Abstract
BACKGROUND/AIM Glioblastoma multiforme (GBM) is a lethal disease with a high rate of chemoresistance to temozolomide (TMZ). The aim of the study was to establish a TMZ-resistant subline from the GBM-8401 cell line to determine the mechanisms of resistance and identify novel effective therapeutics for TMZ-resistant GBM. MATERIALS AND METHODS Comparative transcriptome analysis of GBM-8401/TMZR cells and the parental line was performed using Ion Torrent sequencing. Differentially expressed genes (DEGs) between the GBM-8401/TMZR and GBM-8401 cell lines were analyzed. RESULTS Transcriptomic profiling of GBM-8401/TMZR cells revealed DEGs involved in the retinoblastoma (RB) signaling, DNA damage response (DDR) pathway, and DNA repair mechanisms. CONCLUSION In vitro and in vivo cell-based GBM models should be used in further biomedical studies to investigate the underlying mechanisms of TMZ-resistant GBM.

Abstract
Objective: To investigate the feasibility and safety of auricle reconstruction combined with Bonebridge implantation for bilateral aural atresia patients. Methods: A retrospective analysis was conducted for 36 cases(72 ears) who underwent Bonebridge implantation combined with bilateral auricle reconstruction from February 1, 2017 to January 15, 2020. All cases were bilateral congenital aural atresia and underwent Nagata auricle reconstruction for both sides simultaneously. Bonebridge implantations were performed during the second stage of auricle reconstruction. Results: All 36 patients healed well and had no surgical complications when discharged. The preoperative average bone conduction threshold of the patients was(8.5±5.8) dB HL and postoperative bone conduction threshold was (8.4±5.2) dB HL. There was no significant change after the implantation (P=0.724). The preoperative average air conduction threshold of was(64.9±7.4)dB HL and postoperative air conduction threshold was (24.0±5.3) dB HL, which had a significant change after the implantation (P<0.001). The hearing threshold with Bonebridge significantly decreased by 40.9 dB HL compared with the preoperative air conduction threshold(P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased by 62.5%, 63.5% and 72.2% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words and short sentences in noise environment were significantly increased by 55.9%, 58.9% and 69.9% respectively (P<0.001). After a follow-up of 18.3 months in average, the hearing results were stable and the aesthetic outcomes were satisfied. One patient had implant rupture and healed after revision surgery. Conclusions: With an integrated surgical procedure, patients with bilateral congenital aural atresia can complete bilateral auricle reconstruction and hearing implantation within six months. This integrated surgical procedure is safe and efficient, with a stable hearing improvement and good appearance.

Abstract
In April 2016, the Global Polio Eradication Initiative (GPEI) adjusted its polio vaccination strategy, converting trivalent oral polio vaccine (tOPV) into bivalent oral polio vaccine (bOPV), and withdrawing type 2 oral polio vaccine (OPV2) globally. However, after the withdrawal of OPV2, there were many outbreaks of type-2 circulating vaccine-derived poliovirus (cVDPV2) in Asia and Africa. In order to eradicate poliovirus completely, GPEI launched the research and development of the novel serotype 2 oral polio vaccine (nOPV2) in 2010 and considering whether it is necessary to reuse OPV. This paper summarizes the epidemiological situation of cVDPV2 before and after OPV2's withdrawal, the related factors affecting the reuse of OPV and the related research progress of nOPV2.

The coronavirus disease 2019 (COVID‑19) outbreak, which has caused >46 millions confirmed infections and >1.2 million coronavirus related deaths, is one of the most devastating worldwide crises in recent years. Infection with COVID‑19 results in a fever, dry cough, general fatigue, respiratory symptoms, diarrhoea and a sore throat, similar to those of acute respiratory distress syndrome. The causative agent of COVID‑19, SARS‑CoV‑2, is a novel coronavirus strain. To date, remdesivir has been granted emergency use authorization for use in the management of infection. Additionally, several efficient diagnostic tools are being actively developed, and novel drugs and vaccines are being evaluated for their efficacy as therapeutic agents against COVID‑19, or in the prevention of infection. The present review highlights the prevalent clinical manifestations of COVID‑19, characterizes the SARS‑CoV‑2 viral genome sequence and life cycle, highlights the optimal methods for preventing viral transmission, and discusses possible molecular pharmacological mechanisms and approaches in the development of anti‑SARS‑CoV‑2 therapeutic agents. In addition, the use of traditional Chinese medicines for management of COVID‑19 is discussed. It is expected that novel anti‑viral agents, vaccines or an effective combination therapy for treatment/management of SARS‑CoV‑2 infection and spread therapy will be developed and implemented in 2021, and we would like to extend our best regards to the frontline health workers across the world in their fight against COVID‑19.

Abstract
Objective: To investigate the clinical outcomes and radiographic results of artificial cervical disc replacement (ACDR) for cervical adjacent segment disease (ASD). Methods: The clinical data of 28 patients with single-segment cervical ASD treated with ACDR in Xi 'an Honghui Hospital from December 2013 to July 2016 were retrospectively analyzed. There were 19 males and 9 females with a mean age of (46±7) years (36-63 years). Preoperative, postoperative 1 month and postoperative 24 months of clinical and radiographic outcomes were recorded and compared. The clinical outcome mainly includes Japanese orthopedic association (JOA), Neck Disability Index (NDI%), Odom score and complications. Imaging assessment mainly included range of motion (ROM) of cervical spine, surgical segment ROM, Cobb angle of surgical segment, degree of adjacent disc degeneration, heterotopic ossification, and prosthesis related image parameters. Results: In terms of clinical outcome, the average JOA score was 12.7±1.5 before surgery, 14.0±1.0 one month after surgery, 15.8±0.9 24 months after surgery, and the improvement rate of JOA was 75%±19%. The mean NDI% was 27.0%±2.8% before surgery, 20.5%±1.6% one month after surgery, and 15.3%±2.8% 24 months after surgery; the difference before and after treatment was statistically significant (F=159.101, P<0.01). Twenty patients were classified with excellent Odom score and 8 patients with good Odom score at the final follow-up. The total ROM of cervical spine, operation segment ROM, operation segment Cobb angle were all improved significantly after the operation (F=4.633, 6.063, 26.952, all P<0.05). There was a statistical difference in Miyazaki classification between adjacent discs above ACDR and below the fusion segment 24 months after surgery (μ(c)=2.12, P=0.034). The incidence of heterotopic ossification was 14.3%. The results of displacement degree of prosthesis were as follow: coronal plane (0.30±0.11) mm, sagittal plane (0.28±0.10) mm; subsidence of the prosthesis: (0.27±0.09) mm. No prosthesis loosening was observed. Conclusions: The clinical outcome of revision of cervical ASD by ACDR is satisfactory. The risk of intervertebral disc degeneration in adjacent segments is significantly lower than that of ACDF due to the presence of certain motor function postoperatively.

Abstract
Novel quinazolinone compounds have been studied in the field of drug discovery for a long time. Among their broad range of pharmacological effects, certain compounds effectively inhibit cancer cell proliferation. MJ‑33 is a quinazolinone derivative with proposed anticancer activities that was synthesized in our laboratory. The present study aimed to evaluate the anticancer activity of MJ‑33 in fluorouracil (5FU)‑resistant colorectal cancer cells (HT‑29/5FUR) and to investigate the underlying molecular mechanisms. The cell viability assay results indicated that HT‑29/5FUR cell viability was inhibited by MJ‑33 treatment in a concentration‑dependent manner compared with the control group. The cellular morphological alterations observed following MJ‑33 treatment indicated the occurrence of apoptosis and autophagy, as well as inhibition of cell proliferation in a time‑dependent manner compared with the control group. The acridine orange, LysoTracker Red and LC3‑green fluorescent protein staining results indicated that MJ‑33 treatment significantly induced autophagy compared with the control group. The DAPI/TUNEL dual staining results demonstrated increased nuclear fragmentation and condensation following MJ‑33 treatment compared with the control group. The Annexin V apoptosis assay and image cytometry analysis results demonstrated a significant increase in apoptotic cells following MJ‑33 treatment compared with the control group. The western blotting results demonstrated markedly decreased Bcl‑2, phosphorylated (p)‑BAD, pro‑caspase‑9 and pro‑caspase‑3 expression levels, and notably increased cytochrome c and apoptotic peptidase activating factor 1 expression levels following MJ‑33 treatment compared with the control group. Moreover, the expression levels of autophagy‑related proteins, including autophagy related (ATG)‑5, ATG‑7, ATG‑12, ATG‑16, p62 and LC3‑II, were increased following MJ‑33 treatment compared with the control group. Furthermore, MJ‑33‑treated HT‑29/5FUR cells displayed decreased expression levels of p‑AKT and p‑mTOR compared with control cells. The results suggested that MJ‑33‑induced apoptosis was mediated by AKT signaling, and subsequently modulated via the mitochondria‑dependent signaling pathway. Therefore, the results suggested that suppression of AKT/mTOR activity triggered autophagy in the HT‑29/5FUR cell line. In summary, the results indicated that MJ‑33 inhibited HT‑29/5FUR cell viability, and induced apoptosis and autophagy via the AKT/mTOR signaling pathway. The present study may provide novel insight into the anticancer effects and mechanisms underlying MJ‑33 in 5FU‑resistant colorectal cancer cells.
