Objective: To investigate the coexistence of comorbidity of myopia, overweight/obesity and depressive symptoms among middle school students in Quzhou and its associated factors, so as to provide evidence for integrated prevention and control of common multiple health issues in students. Methods: From September to November 2023, a total of 5 867 middle school students from 6 counties (cities and districts) in Quzhou City were selected by stratified random cluster sampling. Physical and visual examinations were conducted, and the Center for Epidemiological Studies - Depression Scale (CES-D) along with a questionnaire on health status and influencing factors were completed. Multivariate Logistic regression was used to analyze the related factors of coexistence of myopia, overweight/obesity, and depressive symptoms among middle school students, and a nomogram model was constructed based on the results. Results: A total of 161 middle school students in Quzhou City were identified as having comorbid myopia, overweight/ obesity and depressive symptoms, with a detection rate of 2.74%. The results of multivariate Logistic regression analysis showed that the coexistence of myopia, overweight/obesity and depressive symptoms increased among middle school students with older age ( OR =1.11), a greater number unhealthy dietary behaviors (1,2,≥3; OR =2.40, 2.70, 4.63), insufficient sleep( OR =1.78) and alcohol consumption ( OR =2.11)(all P <0.05). Compared with no homework after class, those whose homework duration after class was 1 to < 2 hour had a lower risk of comorbidity of myopia, overweight/obesity and depressive symptoms ( OR =0.53, P <0.05). The results of the nomogram model showed that the AUC (95% CI ) was 0.71 (0.67-0.74). Conclusions The coexistence of myopia, overweight/obesity and depressive symptoms among middle school students in Quzhou City is related to age, sleeping, alcohol consumption, poor dietary behavior and the duration of after school homework. The nomogram model can assist in the early screening and intervention of multiple health issues among students.

Breast cancer is one of the most common cancers in women,but there is currently a lack of accurate prognos-tic assessment systems.The Naples Prognostic Score(NPS)is a prognostic prediction system that incorporates inflammatory and nutritional indicators.It has been proven to have important clinical utility in predicting the prognosis of patients with malignancies such as colon cancer,gallbladder cancer,endometrial cancer,and lung cancer.In recent years,research has found that NPS may be superior to TNMstaging in predicting the prognosis of breast cancer patients.It is an independent predictor of overall sur-vival(OS)and progression-free survival(PFS)in breast cancer patients.This suggests that NPS has great potential for applica-tion in predicting the prognosis of breast cancer.

Objective To compare the differences in gut microbiota between cirrhosis patients receiving transjugular intrahepatic portosystemic shunt(TIPS)and those not,and explore the relationship between TIPS surgery and gut microbiota in order to provide new ideas for improving the prognosis of cirrhosis patients after TIPS surgery based on gut microbiota.Methods Those who had received TIPS surgery previously were assigned into the operation group,and those without the surgery served as the control group.Their stool samples were collected for 16S rRNA sequencing,and the correlation between gut microbiota and clinical indicators was analyzed.Results There were no significant differences in gender,age,body mass index(BMI),etiology and other baseline data between the 2 groups(P＞0.05),but obvious differences were observed in clinical serological indicators between them,including INR,APTT,RBC and PT counts,and HGB,ALP,ALB,total bilirubin(TBIL),and URE levels(P＜0.05).No statistical difference in alpha diversity was observed between the operation group and the control group(P＞0.05),but beta diversity was obviously different(P＜0.01),among which Bacteroides was increased in the operation group(P＜0.01)and Bifidobacterium was increased in the control group(P＜0.05).The function prediction analysis of gut microbiota showed that the metabolism of D-glutamine and D-glutamate(P＜0.05)and biosynthesis with secondary bile acids(P＜0.05)were up-regulated in the operation group compared with the control group.Correlation analysis between clinical indicators and flora indicated that TBIL and direct bilirubin(DBIL)were significantly correlated with the metabolic pathways of Bacteroides and Secondary bile acids biosynthesis.Conclusion Characteristic changes in gut microbiota are found in cirrhosis patients with and without TIPS surgery.Bacteroides may be involved in the regulation of metabolism of bile acids and thus increase bilirubin level.

Objective To analyze the transcription factor binding sites(TFBS)in the promoter region of E3 ubiquitin protein ligase 1(MIB1)gene in zebrafish,the types of MIB1 interacting genes and proteins and their roles in signaling pathways,and to investigate the regulatory mode and potential function of MIB1 gene.Methods Non-coding RNA(ncRNA)was predicted by National Genomics Data Center(NGDC).Alggen and AnimalTFDB online software were used to predict the TFBS types of MIB1 gene.GeneMANIA and STRING were used to analyze the interacting genes and proteins of MIB1.The related data were obtained through DA-VID website,and gene ontology(GO)visual analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)metabolic pathway analysis were performed.Results ncRNA could be transcribed from the promot-er region and 5'untranslated region of MIB1 gene.A total of 121 TFBS were obtained by prediction.P53 tran-scription factor could bind to the promoter region of MIB1 gene and interact with MIB1 protein.A total of 6 co-expressed genes of MIB1 were predicted online,and 20 interacting genes were screened.GO visual analysis showed that MIB1 and its interaction genes had functions in regulating the growth and differentiation of cells,tissues and organs and regulating the NOTCH signaling pathway in the biological process,and were mainly enriched in the cytoplasmic perinuclear region,cell membrane,postsynaptic dense area and so on.It had molec-ular functions such as binding NOTCH proteins and PDZ domain proteins.KEGG metabolic pathway analysis showed that MIB1 and its interacting genes were involved in 4 metabolic pathways.Conclusion MIB1 con-tains a variety of TFBS,and affects a variety of biological processes such as cell carcinogenesis and immune regulation by interacting with specific transcription factors.MIB1 may also play an important role in cell growth regulation,hematopoietic stem cell differentiation,embryonic development and neuronal information transmission through the mediation of its interacting genes and proteins.

Metastasis is the main cause of cancer-related death. Growing evidence has shown that changes in glucose metabolism in nasopharyngeal carcinoma cells affect the invasion and metastasis of nasopharyngeal carcinoma through many pathways. This review summarizes the molecular mechanism underlying abnormal glucose metabolism in nasopharyngeal carcinoma cells and analyzes its relationship with the invasion and metastasis of nasopharyngeal carcinoma, including aerobic glycolysis, aerobic oxidation, and pentose phosphate pathway. The aim is to provide novel approaches using the relationships among glucose metabolism, invasion, and metastasis in the targeted therapy of nasopharyngeal carcinoma.

Objective:To investigate the effect of high glucose on intracellular cholesterol content in rat glomerular mesangial cells and the underlying mechanism.Methods:Rat glomerular mesangial cells were cultured in vitro and divided into high glucose culture group (high glucose group, medium glucose concentration of 30 mmol/L) and normal glucose culture group (normal group, medium glucose concentration of 5.5 mmol/L). Lipid content was determined by oil red O staining and spectrophotometer colorimetry at 24, 36 and 48 h of culture. Intracellular protein imprinting was used to detect the expression of low density lipoprotein cholesterol receptor (LDLR) and adenosine triphosphate binding cassette A1 (ABCA1). Results:Oil red O staining showed that the intracellular lipid drops in the high glucose group were less than those in the normal group at 36 h, and there was no significant difference between the two groups at 24 h and 48 h of culture. The total cholesterol (TC) and cholesterol ester (CE) in glomerular mesangial cells of rats in the high glucose group were significantly lower than those in the normal group ( P=0.028, 0.029), while there was no significant difference in the free cholesterol (FC) between the two groups ( P=0.306). There was no significant difference in TC, CE and FC between the two groups at 24 and 48 h of culture (all P>0.05). The expression of LDLR in mesangial cells of rats in high glucose group was significantly lower than that in normal group at 24, 36 and 48 h of culture ( P=0.043, 0.004, 0.028), and the expression of ABCA1 was significantly higher than that in normal group at 24, 36 and 48 h of culture, ( P=0.050, 0.009, 0.006). Conclusions:High glucose may reduce intracellular cholesterol content in rat glomerular mesangial cells by reducing LDLR protein expression and increasing ABCA1 protein expression.

Objective:To study the genotyping and regional distribution characteristics of Yersinia pestis by single nucleotide polymorphism (SNP) in Gansu Province. Methods:A total of 52 strains of Yersinia pestis isolated from Himalaya Marmot plague foci and Spermophilus alaschanicus plague foci in Gansu Province from 1962 to 2017 were selected for culture and extraction of DNA. The genomic DNA of Yersinia pestis was sequenced by the second generation of Illumina PE150 to identify the SNP sites. The species characteristics of Yersinia pestis in Gansu Province was determined by the Kimura-2-parameter model of neighbor joining of Mega 10.0 software based on the SNP sites. The molecular evolutionary tree of the groups was determined by Hasegawa-Kishino-Yano model of maximum likelihood method according to the SNP sites. Results:A total of 103 SNP sites were identified in 52 strains of Yersinia pestis in Gansu Province, including 28 intergenic loci, 43 non-synonymous mutations, 31 synonymous mutations and 1 nonsense mutation. The 52 strains of Yersinia pestis were divided into 2 biotypes and 3 groups, which were ancient type (1.IN2, 3.ANT) and medieval type (2.MED). Among them, 35 strains belonged to 1.IN2 group, 13 strains belonged to 3.ANT group, and 4 strains belonged to 2.MED group. The 1.IN2 group was further divided into 5 subgroups: the groups of Yuerhong Town and Dangchengwan Town in Subei County, the groups of Mati Town and Dahe Town in Sunan County, and the group of Xiahe County. The 3.ANT group was further divided into 2 subgroups: the groups of Hongliuwan Town in Aksay County and Machang in Dangchengwan Town of Subei County. Conclusion:The SNP method can be used to genotype Yersinia pestis from different plague foci in Gansu Province, which has certain regional characteristics.

Objective:To investigate the surgical technology and clinical efficacy of using the all-inside subtalar arthroscopy through three portals combined with rafting screws technique for the treatment of the calcaneal fractures of Sanders Ⅱ and Ⅲ.Methods:The clinical data of 33 patients (33 feet) with intra-articular displaced calcaneal fractures treated by modified all-inside arthroscopic from March 2017 to March 2019 at Department of Orthopedics,Xuzhou Central Hospital were retrospectively analyzed.There were 19 male patients,and 14 female patients,aged (32.6±11.3) years(range:20 to 55 years). According to the Sanders classification,there were 12 cases of type Ⅱ and 21 cases of type Ⅲ. The duration from injury to surgery was (101.2±32.1) hours(range:6 to 140 hours).The preoperative visual analogue scale (VAS) was 6.4±2.9 (range: 4 to 8); The preoperative American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale and the SF-36 score was 63.3±11.8 (range:50 to 75) and 94.8±9.1 (range:70 to 105) respectively.All the patients were managed with the all-side subtalar arthroscopy through three portals combined with rafting screws technique.The incision healing,reduction of fracture,and fracture healing were recorded.The VAS,AOFAS ankle-hindfoot scale,and SF-36 score were used to assess the pain and functional outcomes.Repeated-measurement was used to compare the scores before and after surgery.Results:The time of operation was (69.7±10.4) minutes (range:40 to 110 minutes). All patients did not undergo bone grafting.The incision healed in one stage without complications of skin sensory and peroneal tendon injury.All patients were followed up for 24 months.At the last follow-up,all the patients were satisfied with the hindfoot alignment,function,and hindfoot appearance.Postoperative calcaneal imaging indicators (calcaneal length,calcaneal width,calcaneal height,Bohler angle and Gissane angle) were significantly improved compared with those before surgery ( P<0.01).There was no statistically significant difference in the imaging indexes of calcaneus at 1 day,1 year and 2 years after surgery,indicating no loss of fracture reduction (all P>0.05).The VAS,AOFAS ankle-hindfoot scale,and SF-36 score were 1.5±0.4 (range: 0 to 2),94.0±6.5 (range:90 to 100),and 119.1±7.2 (range:105 to 130),respectively,which were better than those before surgery (all P>0.05).According to the AOFAS scoring system,27 cases were excellent,4 cases were good, 2 cases were fair,and the excellent and good rate was 94.0%. Conclusion:All-inside subtalar arthroscopy through three portals combined with rafting screws technique for the treatment of the calcaneal fractures of Sanders Ⅱ and Ⅲ provides precise reduction,reliable fixation,satisfactory function and limited complications,which is an alternative method.

Esophageal cancer (EC) is one of the most common cancers with high morbidity and mortality rates. EC includes two histological subtypes, namely esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC). ESCC primarily occurs in East Asia, whereas EAC occurs in Western countries. The currently available treatment strategies for EC include surgery, chemotherapy, radiation therapy, molecular targeted therapy, and combinations thereof. However, the prognosis remains poor, and the overall five-year survival rate is very low. Therefore, achieving the goal of effective treatment remains challenging. In this review, we discuss the latest developments in chemotherapy and molecular targeted therapy for EC, and comprehensively analyze the application prospects and existing problems of immunotherapy. Collectively, this review aims to provide a better understanding of the currently available drugs through in-depth analysis, promote the development of new therapeutic agents, and eventually improve the treatment outcomes of patients with EC.
