Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

OBJECTIVE: To observe the effects of moxibustion at "Feishu" (BL13) and "Xinshu" (BL15) on the circular RNA of exon 2-5 of the Pan3 gene (circPAN3), forkhead box O3 (FOXO3), and Bcl-2/adenovirus E1B19kDa-interacting protein 3 (BNIP3) in rats with chronic heart failure (CHF), and explore the potential mechanisms of moxibustion in alleviating myocardial fibrosis. METHODS: Ten rats of 60 male SPF-grade SD rats were randomly assigned into a normal group. The remaining rats underwent left anterior descending coronary artery (LAD) ligation to establish the CHF model. Forty successfully modeled rats were randomly divided into a model group, a moxibustion group, a rapamycin (RAPA) group, and a moxibustion+RAPA group, with 10 rats in each group. The moxibustion group received mild moxibustion at bilateral "Feishu" (BL13) and "Xinshu" (BL15), 30 min per session. The RAPA group received intraperitoneal injection of the autophagy activator RAPA (1 mg/kg). The moxibustion+RAPA group first received RAPA injection, followed by mild moxibustion at bilateral "Feishu" (BL13) and "Xinshu" (BL15). All interventions were administered once daily for 4 consecutive weeks. After the intervention, cardiac ultrasound was used to measure ejection fraction (EF) and left ventricular fractional shortening (FS). Serum placental growth factor (PLGF) level was determined by ELISA. Myocardial tissue morphology and collagen volume were assessed using hematoxylin-eosin (HE) staining and Masson's trichrome staining. The expression levels of circPAN3, FOXO3, and BNIP3 mRNA in myocardial tissue were detected by real-time PCR, while FOXO3 and BNIP3 protein expression levels were analyzed by Western blot. RESULTS: Compared with the normal group, the model group exhibited myocardial cell disorder, severe fibrosis, and increased collagen volume (P<0.01), along with significantly decreased EF, FS, and circPAN3 mRNA expression in myocardial tissue (P<0.01), and the serum PLGF level, as well as FOXO3 and BNIP3 mRNA and protein expression in myocardial tissue were increased (P<0.01). Compared with the model group, the moxibustion group showed reduced myocardial fibrosis, decreased collagen volume (P<0.01), increased EF, FS, and circPAN3 mRNA expression in myocardial tissue (P<0.01), and decreased serum PLGF level as well as FOXO3 and BNIP3 mRNA and protein expression in myocardial tissue (P<0.01). Compared with the model group, the RAPA group showed further deterioration in these parameters (P<0.01). Compared with the RAPA group, the moxibustion+RAPA group exhibited alleviation of myocardial fibrosis, reduced collagen volume (P<0.01), increased EF, FS, and circPAN3 mRNA expression in myocardial tissue (P<0.01), and decreased serum PLGF level as well as FOXO3 and BNIP3 mRNA and protein expression in myocardial tissue (P<0.01). CONCLUSION Moxibustion could alleviate myocardial fibrosis in CHF rats, possibly through upregulation of myocardial circPAN3 expression, downregulation of FOXO3 and BNIP3 expression, and inhibition of excessive myocardial autophagy.

OBJECITVE: To investigate the effectiveness of three-dimensional (3D) printing-assisted vascularized fibular graft for repairing metatarsal defects. METHODS: Between November 2021 and February 2024, 11 patients with varying degrees of metatarsal defects caused by trauma were treated. There were 10 males and 1 female, aged 22-67 years, with a mean age of 51.2 years. The defect locations were as follows: the first metatarsal in 4 cases, the fifth metatarsal in 2 cases, the first and the second metatarsals in 1 case, the first to third metatarsals in 1 case, the third and the fourth metatarsals in 1 case, the third to fifth metatarsals in 1 case, and the first to fifth metatarsals in 1 case. The preoperative American Orthopaedic Foot & Ankle Society (AOFAS) score was 67.0 (48.5, 72.5). Based on 3D-printed bilateral feet models and mirrored healthy-side foot arch angles for preoperative planning and design, the vascularized fibular graft was performed to repair the metatarsal defects. At last follow-up, the medial and lateral longitudinal arches of bilateral feet were measured on weight-bearing X-ray films, and functional assessment was conducted using the AOFAS score. RESULTS: All operations were successfully completed, with an operation time ranging from 180 to 465 minutes (mean, 246.8 minutes). All incisions healed by first intention, with no occurrence of osteomyelitis. All patients were followed up 6-22 months (mean, 10 months). X-ray film reviews showed bone graft healing in all cases, with a healing time of 3-6 months (mean, 5 months). All patients underwent internal fixator removal at 6-12 months after operation. At last follow-up, no significant difference was observed in the medial and lateral longitudinal arches between the healthy and affected feet ( P>0.05). The AOFAS score of the affected foot was 78.0 (73.5, 84.0), showing a significant improvement compared to the preoperative score ( P<0.05). The effectiveness was rated as excellent in 1 case, good in 7 cases, fair in 2 cases, and poor in 1 case. Linear scarring remained at the donor site, with no functional impairment in adjacent joint movement. CONCLUSION 3D printing-assisted vascularized fibular graft for repairing metatarsal defects can effectively restore the physiological angle of the foot arch, facilitate the recovery of weight-bearing alignment, promote good bone healing, and yield satisfactory clinical outcomes.

Objective To understand cognition level and treatment intention of patients with endometriosis(EMs);To evaluate the effects of TCM chronic disease management on EMs patients.Methods The disease cognition level and treatment intention of 1 895 EMs patients from October 2020 to December 2021 in 19 provinces,autonomous regions and municipalities were analyzed through cross-sectional investigation.The cognitive effect of chronic disease management of TCM on 801 patients with EMs from 6 Grade A hospitals in Beijing was evaluated by self-control study.Results The cognition level of EMs patients for the disease was improved with the increase of educational background.Patients generally believed that EMs was a chronic disease,requiring regular review and long-term management.The proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the possibility of malignant changes in EMs was less,only 32.3%,41.6%and 47.7%,respectively.The awareness rate of patients with high school education or below for recurrence after EMs conservative surgery was 46.9%,lower than that of those with junior college education(66.8%)and bachelor degree or above(72.7%).Among the patients with dietary contraindications,the proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the contraindication of the forest frog oil was less,only 20.7%,30.3%and 32.9%,respectively.In the aspect of life adjustment,the awareness of patients was generally high.EMs patients mainly recognized the disease through face-to-face communication with gynecologists.Only 34.4%of patients with high school education or below learned about EMs through WeChat public accounts,APPs and other new media,which was lower than those with junior college education(48.6%)and bachelor degree or above(55.4%).EMs patients generally tend to be treated in comprehensive hospitals,with high acceptance of TCM treatment,mainly TCM decoction,and low acceptance of TCM appropriate technology.After 1 year of TCM chronic disease management,the disease awareness of EMs patients was significantly improved compared with before management,with statistical significance(P<0.05).Conclusion EMs patients with different educational backgrounds have different cognition of the disease,and each has different emphasis.Education and popularization should be carried out according to their knowledge blind spots.Chronic disease management of TCM can improve the disease cognition level of EMs patients.

Objective To explore the material basis and mechanism of the Chinese medicine Dingqing tablets in the treatment of leukemia.Methods The potential active ingredients of Dingqing tablets were retrieved through TCMSP and HERB Database and the targets of herbs were screened by Swiss TargetPrediction databases.The treatment targets of leukemia were searched from the GeneCards,OMIM and Disgenet databases.The protein-protein interaction network was used to construct the interactive target regulation function of Dingqing tablets and leukemia by STRING software,and the core subnetworks were filtered by the MCODE plug-in.A component-target pathway network was constructed by GO and KEGG enrichment analysis of the highest scoring Gene cluster 1 gene in the DAVID database.Molecular docking of the active components and core targets of Dingqing tablets was performed by AutoDock and the results were visualized.Results A total of 82 active ingredients and 439 targets of action of Dingqing tablets,and 1 878 leukemia-related targets were obtained through database retrieval,in which 169 common targets of active ingredients and diseases were mapped.Based on the degree values,the main active ingredients were determined as quercetin,luteolin,kaempferol,etc.The PPI core network indicated that the key targets for treating leukemia included TP53,MMP9,TNF,AKT1,CASP3,etc.The gene enrichment analysis of sub-networks and the component-target pathway network diagram showed that Dingqing tablets might exert therapeutic effects on leukemia by regulating signaling pathways such as TNF and IL-17.The molecular docking results showed fairly strong binding activity between the active ingredients and the targets.Conclusion The active ingredients of Dingqing tablets may participate in TNF,IL-17,and other signaling pathways by regulating genes such as TP53,AKT1,and CASP3,thereby exerting therapeutic effects on leukemia.

Objective:To explore the genetic basis of two children with unexplained psychomotor developmental delay and facial dysmorphisms suggestive of Coffin-Siris syndrome (CSS).Methods:A boy and a girl suspected for CSS at the 980th Hospital of the People′s Liberation Army Joint Service Support Force respectively in July 2019 and January 2021, and seven members from their families, were selected as the study subjects. Clinical data and family history of the children were collected, and detailed physical examination was carried out, in addition with laboratory and related auxiliary examinations. Potential variants and copy number variations (CNVs) were detected by whole exome sequencing (WES) and copy number variation sequencing (CNV-seq).Results:Child 1, an 8-month-old female, had featured microcephaly, atrial septal defect, curving of fifth finger/toe, and low limb muscle tone. Child 2 was a 2.5-year-old male with language delay, social impairment, dense hair but no curving of the fifth fingers. Genetic testing revealed that child 1 had loss of heterozygosity for exons 8 to 21 of the ARID1B gene, which was unreported previously. Family verification showed that both of her parents were of the wild type. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG) and American Society of Molecular Pathology (AMP), the variant was rated as pathogenic (PVS1+ PS2+ PM2-supporting). Child 2 was found to harbor a heterozygous c. 4263-6 (IVS17) T>G variant of the ARID1B gene. Transcriptome sequencing confirmed that the variant can affect the normal splicing, resulting in retention of a 5 bp sequence in intron 17. Family verification showed that both of his parents were of the wild type. Based on the guidelines from the ACMG, the variant was rated as pathogenic (PS2+ PM2-supporting+ PP3+ PS3). Conclusion:WES and RNA-seq have confirmed the diagnosis of CSS in both children. Discovery of the novel variants has expanded the spectrum of pathogenic mutations underlying CSS, and provided a basis for the genetic counseling.

Objective:To compare and analyze the clinical characteristics of acute myeloid leukemia (AML) related to the treatment of hematological tumors and solid tumors.Methods:The laboratory and clinical data of 41 patients with treatment-related AML (t-AML) in the Department of Hematology, Henan Cancer Hospital from January 2014 to December 2021 were retrospectively analyzed, and they were divided into hematological tumor group and solid tumor group. Survival analysis was performed using the Kaplan-Meier method and Log rank test.Results:The median interval from the first tumor diagnosis to t-AML in 41 patients was 21.0 (16.5-46.0) months; 24 (58.5%) had abnormal expression of lymphoid antigen, 28 (68.3%) had abnormal karyotype, 18 cases (43.9%) were positive for fusion gene, and 28 cases (68.3%) were positive for gene mutation; the median recurrence-free survival (RFS) was 11.0 months, and the median overall survival (OS) was 11.5 months. The proportion of acute promyelocytic leukemia ([APL], 0.0, 0/13), complete response ([CR],18.2%, 2/11), median OS (4.5 months) and median RFS (2.5 months) of t-AML patients in the hematological tumor group were significantly lower than those in the solid tumor group (35.7%, 10/28; 68.0%, 17/25; not reach; not reach), but the proportion of M4 /M5 (93.2%,12/13) was significantly higher than that in the solid tumor group (53.6%,15/18; all P values<0.05). Through subgroup analysis, the proportion of patients with positive PML-RARa and good prognosis karyotypes in the solid tumor group (35.7%, 10/28; 46.4%, 13/28) was significantly higher than that in the hematological tumor group (0.0, 0/13; 0.0, 0/13; P<0.05), while the proportion of patients with intermediate karyotypes (42.9%, 12/28) was significantly lower than that in the hematological tumor group (84.6%, 11/13; P<0.05), the difference was statistically significant. The CR rate (90.0%, 9/10), median OS (not reach) and median RFS (not reach) in the t-APL group were higher than those in the t-AML (without t-APL) group (38.5%, 10/26; 6 months; 8 months; P<0.05). After excluding the effect of t-APL patients, there was no significant difference in the CR rate, median OS and median RFS between the solid tumor group (8; 9 months; not reach) and the hematological tumor group (2; 4 months; 2 months; P>0.05). Univariate analysis showed that the primary tumor belongs to hematological tumor was a common risk factor for OS and RFS in t-AML patients ( P<0.10). Conclusions:Compared with patients with t-AML secondary to solid tumors, patients with t-AML secondary to hematological tumors have poorer treatment effects and poorer prognosis. After excluding the effect of t-APL patients, there are no significant differences in the treatment efficacy and prognosis between the two types of t-AML patients.

Objective:To analyze the differential expressions of proteins in aqueous humor in patients with exfoliation syndrome (XFS).Methods:A total of 20 patients were enrolled in the Department of Ophthalmology, People's Hospital of Hotan District from June 2020 to January 2021, including 10 patients with age-related cataract and 10 XFS patients combined with cataract, which were classified as cataract group and XFS group, respectively.A total of 50 to 100 μl aqueous humor was obtained in the middle of the anterior chamber through the intraoperative phacoemulsification channel.The proteins extracted from aqueous humor were analyzed by label-free quantitative proteomics technology.The cataract group was set as the control group, and the differentially expressed proteins (DEPs) in XFS group were screened according to P<0.05 and fold change >1.5.Gene ontology (GO) function analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway analysis were used to explore the function and regulatory signaling pathways of DEPs in the XFS group.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2020KY[L]-21).Written informed consent was obtained from each subject. Results:In comparison with the cataract group, 25 DEPs were identified in the XFS group, primarily involved in cell adhesion, receptor, hydrolase, and molecular transport.Specifically, there were 14 down-regulated proteins including complement factor H-related protein 1 (CFHR1), endoplasmic reticulum chaperone BiP (HSPA5), biglycan (BGN), FRAS1-related extracellular matrix protein 2 (FREM2), hemoglobin subunit delta (HBD), hemoglobin subunit gamma-1 (HBG1), lysosomal thioesterase PPT2 (PPT2) etc., and 11 up-regulated proteins including latent-transforming growth factor beta-binding protein 2 (LTBP2), very low-density lipoprotein receptor (VLDLR), laminin subunit alpha-2 (LAMA2), coagulation factor Ⅸ (F9).Among them, FREM2 was the most significantly differentially expressed protein in XFS group with consistent expression levels across individual samples.GO analysis revealed that these DEPs mainly localized to the extracellular matrix of collagen, bound globin-hemoglobin complex, plasma lipoprotein particles and lysosomes.Molecular functions and biological processes showed that HBD and HBG1 were involved in cellular detoxification, PPT2 in hydrolase activity, and BGN and LTBP2 in glycosaminoglycan binding.KEGG signaling pathway analysis indicated that CFHR1 and F9 were associated with complement and coagulation cascade pathways, and FREM2 and LAMA2 were linked to the extracellular matrix interaction pathway.Conclusions:Disease progression of XFS may be associated with changes in extracellular matrix proteins, disruption of the blood-aqueous humor barrier, and potential inflammatory responses.The significant down-regulation of FREM2 protein may be a potential biomarker for XFS.

Objective:To compare the therapeutic effects of 0.05% cyclosporine and 0.1% fluorometholone eye drops in patients with moderate and severe dry eye.Methods:A randomized controlled study was conducted.Fifty-two patients (52 eyes) with moderate to severe dry eye in Tianjin Medical University Eye Hospital from August 2021 to December 2022 were enrolled and randomly divided into 0.05% cyclosporine group and 0.1% fluorometholone group by random number table method, with 26 cases (26 eyes) in each group.Patients received 0.05% cyclosporine eye drops (2 times/day) and 0.1% fluorometholone eye drops (2 times/day) combined with calf blood deproteinized extract eye drops (4 times/day) according to the grouping.Before and 1, 3 and 6 months after treatment, clinical symptoms and signs were observed and Ocular Surface Disease Index (OSDI) score, corneal fluorescein staining (CFS) score, Schirmer Ⅰ test (SⅠT), non-invasive first tear film break-up time (NIBUTf), and conjunctival goblet cell (CGC) density were recorded.Before treatment and after 6 months of treatment, changes in corneal nerves and dendritic cells (DC) were observed by in vivo confocal microscopy (IVCM).This study adhered to the Declaration of Helsinki and was approved by the Medical Ethics Committee of Eye Hospital of Tianjin Medical University (No.2021KY-17).Written informed consent was obtained from each subject. Results:Compared with the 0.1% fluorometholone group, CFS score decreased after 1 month of treatment, but SⅠT, NIBUTf and CFS score increased after 3 months of treatment, and OSDI score, SⅠT and CFS score decreased after 6 months of treatment in the 0.05% cyclosporine group, showing statistically significant differences (all at P<0.05).Compared with baseline, in the 0.05% cyclosporine group, NIBUTf increased and CFS score decreased after 1 month of treatment, OSDI score and CFS score decreased, SⅠT and NIBUTf increased after 3 and 6 months of treatment, showing statistically significant differences (all at P<0.05).In the 0.1% fluorometholone group, CFS score decreased after 3 months of treatment, OSDI score and CFS score decreased, SⅠT increased after 6 months of treatment compared to baseline, showing statistically significant differences (all at P<0.05).OSDI score and CFS score decreased, SⅠT increased after 6 months of treatment compared to 3 months of treatment in the 0.05% cyclosporine group, and the differences were statistically significant (all at P<0.05).Baseline and CGC densities after 1, 3 and 6 months of treatment were (147.66±17.29), (195.44±15.46), (210.36±19.15) and (282.09±22.63)cells/mm 2 in the 0.05% cyclosporine group and (138.09±17.29), (95.67±15.46), (117.77±19.15) and (109.13±22.63)cells/mm 2 in the 0.1% fluorometholone group, respectively, with a statistically significant overall difference ( Fgroup=11.724, P<0.001; Ftime=4.837, P=0.005).Compared with the 0.1% fluorometholone group, CGC density in the 0.05% cyclosporine group increased after 1, 3 and 6 months of treatment, with statistically significant differences (all at P<0.05).Compared with baseline, the CGC density increased in the 0.05% cyclosporine group after 1, 3 and 6 months of treatment, and the differences were statistically significant (all at P<0.05).Compared with the 0.1% fluorometholone group, the corneal nerve fiber density in the 0.05% cyclosporine group increased after 6 months of treatment, and corneal DC density, area and dendrite number decreased, showing statistically significant differences (all at P<0.05). Conclusions:Cyclosporine 0.05% eye drops combined with calf blood deproteinized extract eye drops can improve symptoms and signs in patients with moderate to severe dry eye, and the long-term effect is better than that of 0.1% fluorometholone plus calf blood deproteinized extract eye drops.

Objective:To analyze the detection of colorectal advanced neoplasms in the population who underwent colonoscopy screening in Henan Province as part of the Urban China Cancer Screening Program and its influencing factors.Methods:A cross-sectional study design was employed. Based on the Cancer Screening Program conducted in Henan Province, the study enrolled 7 454 urban residents who manifested no symptoms and were recruited from eight cities in the province, including Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Xinxiang, and Puyang from October 2013 to October 2019, and participated in colonoscopy screening. The χ 2 test was used to compare the detection rates of colorectal advanced neoplasms among participants with different characteristics, and a multivariate logistic stepwise regression model was used to analyze the factors affecting the detection rates. Results:A total of 7 454 subjects underwent colonoscopy screening, and 112 cases of colorectal advanced neoplasms were detected. Multivariate logistic regression analysis suggested that older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative were risk factors for colorectal advanced neoplasms. The detection rate was significantly higher in people aged 60-74 years compared with those aged 40-49 years, with an odds ratio ( OR) of 2.04 (95% CI: 1.23-3.38).The rates were higher in people who smoked than those who did not smoke, with an OR of 2.21 (95% CI: 1.48-3.31), and in people who consumed more meat than those who consumed less, with an OR of 1.53 (95% CI: 1.04-2.26). Those with diabetes had a higher detection rate compared with those without, with an OR of 1.69 (95% CI: 1.07-2.69), and those with a first-degree family history of colorectal cancer had a higher detection rate than those without, with an OR of 1.64 (95% CI: 1.09-2.46). Conclusion:The detection rate of colorectal advanced neoplasms through colonoscopy screening in Henan Province covered by the Urban China Cancer Screening Program is 1.50%. Older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative are identified as risk factors for colorectal advanced neoplasms.
