Background As a pillar industry in China, the manufacturing sector has a high incidence of non-fatal occupational injuries. The factors influencing non-fatal occupational injuries in this industry are closely related at various levels, including individual, equipment, environment, and management, making the analysis of these influencing factors complex. Objective To identify influencing factors of non-fatal occupational injuries among manufacturing workers, providing a basis for targeted interventions and surveillance. Methods A total of 2243 frontline workers from cable and shipbuilding enterprises were selected as study subjects to investigate the incidence of non-fatal occupational injuries and collect information at four levels: individual, equipment, management, and environment in past 12 months. Data balancing was performed using resampling, and LASSO regression was used to select factors of non-fatal occupational injuries. The influence degree and type of variables were judged based on the magnitude of the estimated coefficients of each variable, where variables with estimated coefficients > 0 are risk factors, and those <0 are protective factors. The area under the receiver operating characteristic (ROC)curve (AUC) was used to test the performance of the model, with an AUC value > 0.7 indicating good model performance. Results Among the 2243 frontline workers, males accounted for 77.7% (1742 out of 2243), with the main age range being 40-49 years old, representing 29.5% (661 out of 2243), 82.7% of the workers (1854 out of 2243) were married, and 55.6% (1248 out of 2243) had a junior middle school education level. The average monthly income for 51.0% (1144 out of 2243) of the workers was between 5000 and 6999 Chinese Yuan. The incidence of non-fatal occupational injuries among the manufacturing workers was 8.4% (189/2243) in the past 12 months. Among the 22 factors associated with the occurrence of non-fatal occupational injuries (P<0.05), 10 were individual-level factors, including gender, smoking, alcohol consumption, colleague relationships, average exercise duration, job burnout, work fatigue, musculoskeletal disorders, cardiovascular diseases, and neurological and sensory organ diseases; 3 were equipment-level factors, including equipment operability, hazardous workpieces, and safety hazards; 5 were environmental-level factors, including low temperatures, special operations, noise, workspace size, and dirty and disorderly environment; and 4 were management-level factors, including daily working hours, weekly working days, overtime, and pre-job technical training. The AUC value of the LASSO regression model was 0.704 and the final model retained a total of 10 variables. Among them, there were 7 risk factors for non-fatal occupational injuries (coefficient > 0), including safety hazards, musculoskeletal disorders, dangerous workpieces, job burnout, dirty and disorderly environment, smoking, and male gender; and 3 protective factors (coefficient < 0), including pre-job technical training, good colleague relationship, and long working days per week. Conclusion Manufacturing enterprises need to focus on the incidence of non-fatal occupational injuries and conduct targeted interventions for non-fatal occupational injuries by controlling potential safety hazards, providing pre-job technical training, reducing dangerous workpieces, rectifying working environment, and reasonably arranging working hours.

Objective:To investigate the effects of RNA binding protein 15(RBM15)on the malignant biological behaviors of cervical cancer cells by regulating the Wnt/β-catenin pathway through ATPase family AAA-domain containing 3A(ATAD3A).Methods:TCGA database was used to analyze the expression level of RBM15 mRNA in cervical cancer tissues and its relationship with patient prognosis.32 samples of cervical cancer tissues and adjacent para-cancerous tissues surgically removed in Ganzhou People's Hospital between January and October 2024,as well as cervical cancer cells HeLa,MS-751,C-33A,and SiHa,were collected.The expression levels of RBM15 in cervical cancer tissues and cells were detected by immunohistochemistry and WB assay.m6A modification sites in ATAD3A mRNA were screened by the SRAMP online database.The interaction between RBM15 and ATAD3A mRNA were identified by RNA immunoprecipitation assay,RNA decay assay,and salvage assay.Knockdown or overexpression of RBM15 and ATAD3A in cervical cancer HeLa and SiHa cells were conducted by RNA interference and viral infection.The expressions of mRNA and protein were detected by qPCR and WB methods,while the proliferation,migration,and invasion abilities of cells in each group were assessed by CCK-8 method,scratch assay,and Transwell assay.Results:The positivity rates of RBM15 mRNA and protein in cervical cancer tissues were significantly higher than those in adjacent para-cancerous tissues(both P<0.001).The protein expression levels of RBM15 in cervical cancer cell lines HeLa,MS-751,C-33A,and SiHa were significantly higher than those in normal cervical cell lines Ect1/E6E7(all P<0.001).The 5-year progression free survival rate of the RBM15 mRNA high expression group was lower than that of the low expression group(P<0.001).Compared with that in adjacent para-cancerous tissues,the expression level of ATAD3A was significantly upregulated in cervical cancer tissues(P<0.001).RBM15 mRNA was positively correlated with ATAD3A mRNA(r=0.601,P<0.05).There were highly reliable m6A modification sites at position 501,5 312,12 137 in ATAD3A mRNA.Overexpression of RBM15 in HeLa and SiHa cells led to an increase in ATAD3A mRNA and protein expressions,while knockdown of RBM15 resulted in a decrease in ATAD3A mRNA and protein expression(all P<0.001).RNA immunoprecipitation experiment showed that compared with the IgG group,ATAD3A mRNA was significantly enriched in the immunoprecipitation of RBM15 antibody(both P<0.001).MeRIP-qPCR experiment showed that there was significant m6A methylation enrichment at positions ATAD3A mRNA 501,5 312 and 12 137(all P<0.001).RNA decay experiments showed that knocking down RBM15 in HeLa and SiHa cells could reduce the half-life and stability of ATAD3A mRNA(all P<0.001).Knocking down the expression of RBM15 in HeLa and SiHa cells could significantly inhibit the proliferation,migration,and invasion of cancer cells and significantly reduce the expressions of Wnt/β-catenin pathway related proteins Wnt3,β-catenin,and vimentin,while overexpression of ATAD3A could completely reverse the above inhibiting effects(all P<0.001).Conclusion:RBM15 can modify ATAD3A mRNA and regulate the Wnt/β-catenin pathway through m6A,and thus promote the proliferation,migration and invasion of cervical cancer cells.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

Objective To explore the clinical significance of serum cytokine expression in the hepatitis B surface antigen(HBsAg)sero-clearance in patients with severe hepatitis B.Methods A nested case-control trial was conducted on 14 inpatients with severe hepatitis B admitted in our hospital from 2006 to 2020.Of them,7 patients(aged 36.57±3.15 years)achieved HBsAg sero-clearance within 1 year after the onset of hepatitis B flares(with abrupt rise of ALT level to＞5 times the upper limit of normal during HBV infection)and were assigned into HBsAg clearance group,while the other 7 patients(aged 34.14±2.97 years)only obtained HBsAg decreased less than 1 g within 1 year after the onset(HBsAg non-clearance group).Then,multiplex liquid-chip assay based on Luminex xMAP was used to detect the expression levels of 48 cytokines such as IFN-γ and IL-2 in serum samples of these 14 patients.Results The serum levels IFN-γ,IL-2Ra and SDF-1α were significantly lower in the HBsAg clearance group than the HBsAg non-clearance group(P＜0.05),but no statistical differences were observed in other 39 cytokines between the 2 groups.And there were 5 cytokines having no mutual expression in both groups.The copy number of HBV DNA was positively correlated with serum HGF(r=0.675,P=0.008)and SDF-1α levels(r=0.587,P=0.027),while negatively with IP-10(r=-0.600,P=0.023)and MIG level(r=-0.640,P=0.014).Meanwhile,a positive correlation was found between HBsAg titer and IL12-p70 level(r=0.593,P=0.025),and a negative correlation between HBsAg titer and TNF-α level(r=-0.609,P=0.021).In addition,the serum total bilirubin level was positively correlated with the expression of SCGF-β(r=0.543,P=0.045).Conclusion Three differentially expressed cytokines and some cytokines related to HBV DNA level and HBsAg titer are found,which may provide new insights into the underlying immunological mechanism of HBV virus clearance caused by hepatitis flares.Meanwhile,it also provides potential biomarkers for HBsAg serological clearance in patients with severe hepatitis B.

Objective To investigate the prognosis of patients with hepatitis B virus(HBV)-related intrahepatic cholangiocarcinoma(ICC)whose HBV DNA was negative before surgical.Methods A retrospective analysis was conducted on the clinical data of 97 ICC patients who underwent surgery resection at the Fifth Medical Center of Chinese PLA General Hospital between October 2010 and January 2017.All patients were divided into HBV-related ICC(HBV-ICC)group(n=62)and non-HBV-related ICC(Con-ICC)group(n=35).HBV-ICC group included 34 patients with HBV core antigen positive(HBcAb+)and HBV surface antigen positive(HBsAg+),and 28 patients with HBcAb positive and HBsAg negative.Kaplan-Meier analysis was used to plot survival curves and compare the overall survival(OS)and postoperative recurrence-free survival(RFS)among patients in Con-ICC,ICC patients with HBsAg+/HBcAb+,and ICC patients with HBsAg-/HBcAb+.Univariate and multivariate Cox proportional hazard models were used to analyze independent influencing factor for OS,RFS and early postoperative recurrence among gender,age,pathogenic factor,liver cirrhosis,Child-Pugh grade,carbohydrate antigen 19-9(CA199),alpha-fetoprotein(AFP),glutamine transferase(GGT),alkaline phosphatase(ALP),total bilirubin(TBil),direct bilirubin(DBil),American Joint Committee on Cancer(AJCC)stage,tumor size,tumor number,tumor differentiation,microvascular invasion,lymph node metastasis,hepatectomy procedure,cholecystectomy,and follow-up treatment.Results Of the 97 patients,the median age was 56 years,and 79(81.4%)of them were male.The median follow-up time was 92.2 months.Eighty-eight(90.7%)patients presented with tumor recurrence and 73(75.3%)died.In multivariate analyses,HBV-ICC and CA199>37 kU/L were independent predictors of OS(HR=0.45,95%CI 0.26-0.77,P=0.003;HR=2.10,95%CI 1.24-3.57,P=0.006),RFS(HR=0.43,95%CI 0.27-0.68,P<0.001;HR=1.78,95%CI 1.12-2.81,P=0.014),and postoperative early recurrence(HR=0.42,95%CI 0.26-0.70,P=0.001;HR=2.02,95%CI 1.20-3.39,P=0.008).AJCC stage Ⅲ was an independent risk factor for postoperative RFS(HR=1.81,95%CI 1.04-3.14,P=0.037).Multiple tumor lesions was an independent risk factor for postoperative RFS and early recurrence(HR=1.73,95%CI 1.07-2.77,P=0.024;HR=1.90,95%CI 1.12-3.24,P=0.017).There was no statistically significant difference in OS,RFS,and early recurrence between HBV-ICC patients with HBsAg-/HBcAb+and Con-ICC patients(P<0.05),whereas HBsAg+/HBcAb+was a significant factor affecting postoperative OS(HR=0.32,95%CI 0.16-0.62,P=0.001),RFS(HR=0.32,95%CI 0.18-0.55,P<0.001),and early recurrence(HR=0.29,95%CI 0.15-0.54,P<0.001)in ICC patients.Conclusions The prognosis of HBV-ICC patients with preoperative HBV-DNA-is better than that of Con-ICC patients.The prognosis of HBV-ICC patients with HBcAb+/HBsAg-is worse than that of HBV-ICC patients with HBcAb+/HBsAg+,but similar to Con-ICC patients.Therefore,the postoperative stratified management of HBV-ICC patients should be emphasized.

Objective: To explore whether hsa_circ_0000670 promotes the progression of gastric cancer by regulating the miR-515-5p/SIX1 molecular axis. Methods: The gastric cancer and adjacent normal tissues of 35 gastric cancer patients admitted to Rugao Hospital Affiliated to Nantong University from 2014 to 2015 were collected. The expression levels of circ_0000670, miR-515-5p and Sine oculis homeobox 1 (SIX1) in gastric cancer tissues and cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The correlations between circ_0000670 and miR-515-5p, miR-515-5p and SIX1, circ_0000670 and SIX1 were analyzed by the Pearson method. Patients were divided into low circ_0000670 expression group (17 cases) and high circ_0000670 expression group (18 cases) based on the median of circ_0000670 expression level, and Kaplan-Meier was used to analyze the 5-year survival of patients. Cell proliferation was assessed via clone formation assay. Cell cycle and apoptosis were detected by flow cytometry. Wound healing and Transwell assays were used to detect cell migration and invasion ability. The targeting relationship between miR-515-5p and circ_0000670 or SIX1 was confirmed by the dual luciferase reporter assay. Nude mice were injected into HGC-27 cells transfected with sh-NC or sh-circ_0000670, and the volume and weight of the transplanted tumor were measured, also, the levels of circ_0000670, miR-515-5p and SIX1 in the transplanted tumor tissue were detected. Results: The expression levels of circ_0000670 and SIX1 in gastric cancer tissues and cell lines were significantly increased (P<0.05), while the expression levels of miR-515-5p were significantly decreased (P<0.05). The survival rate of patients in the low circ_0000670 expression group (82.4%) was significantly higher than that in the high circ_0000670 expression group (28.7%, P=0.034). Circ_0000670 was negatively correlated with miR-515-5p (r=-0.846, P<0.001), and miR-515-5p was negatively correlated with SIX1 (r=-0.615, P<0.001), but circ_0000670 was positively correlated with SIX1 (r=0.814, P<0.001). Transfection of si-circ_0000670 or miR-515-5p mimic could significantly reduce the number of clone-forming cells, migration distance, migration and invasion cells (P<0.05), and increase the ratio of G(0)/G(1) phase cells, apoptosis rate and the protein level of E-cadherin (P<0.05), decreased the proportion of S-phase cells and the protein level of Vimentin (P<0.05). The dual luciferase report assay confirmed that circ_0000670 could target miR-515-5p, and miR-515-5p could bind to SIX1. Co-transfection of si-circ_0000670 and miR-515-5p inhibitor could significantly attenuate the effects of si-circ_0000670 on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Co-transfection of miR-515-5p mimic and pcDNA-SIX1 could significantly reduce the effects of miR-515-5p mimic on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Compared with the sh-NC group [volume=(596.20±125.46) mm(3) and weight=(538.00±114.39) g], the volume and weight of transplanted tumors in the sh-circ_0000670 group [volume=(299.20±47.58) mm 3 and weight=(289.80±48.73 g)] were significantly reduced (P<0.05), the expression levels of circ_0000670 and SIX1 were significantly reduced (P<0.05), and the expression level of miR-515-5p was significantly increased (P<0.05). Conclusion: Knockdown of circ_0000670 could inhibit cell proliferation, migration, invasion of gastric cancer cells, induce cell cycle arrest in G(0)/G(1) phase and promote cell apoptosis by regulating the miR-515-5p/SIX1 axis.

Renal outer medullary potassium (ROMK) channel is an important K⁺ excretion channel in the body, and K⁺ secreted by the ROMK channels is most or all source of urinary potassium. Previous studies focused on the ROMK channels of thick ascending limb (TAL) and collecting duct (CD), while there were few studies on the involvement of ROMK channels of the late distal convoluted tubule (DCT2) in K⁺ excretion. The purpose of the present study was mainly to record the ROMK channels current in renal DCT2 and observe the effect of high potassium diet on the ROMK channels by using single channel and whole-cell patch-clamp techniques. The results showed that a small conductance channel current with a conductance of 39 pS could be recorded in the apical membrane of renal DCT2, and it could be blocked by Tertiapin-Q (TPNQ), a ROMK channel inhibitor. The high potassium diet significantly increased the probability of ROMK channel current occurrence in the apical membrane of renal DCT2, and enhanced the activity of ROMK channel, compared to normal potassium diet (P < 0.01). Western blot results also demonstrated that the high potassium diet significantly up-regulated the protein expression levels of ROMK channels and epithelial sodium channel (ENaC), and down-regulated the protein expression level of Na⁺-Cl^- cotransporter (NCC). Moreover, the high potassium diet significantly increased urinary potassium excretion. These results suggest that the high potassium diet may activate the ROMK channels in the apical membrane of renal DCT2 and increase the urinary potassium excretion by up-regulating the expression of renal ROMK channels.

AIM: To compare the thickness of retina in macular area and retinal nerve fiber layer(RNFL)around optic disc between the eyes of monocular anisometropic amblyopia children and normal eyes.METHODS: A total of 62 children(124 eyes)with monocular anisometropic amblyopia who were treated in Chengdu Women's and Children's Central Hospital from January 2021 to October 2022 were selected as the experimental group, and 60 children(60 eyes; right eye)with normal vision who were treated in the same period were selected as the control group. Spectral-domain optical coherence tomography(SD-OCT)was used to detect the retinal thickness in macular region and the RNFL thickness around optic disc in the two groups, and comparative analysis was performed.RESULTS: The retinal thickness and perioptic RNFL thickness of amblyopic children in experimental group were thicker than those in control group, and most of them had significant differences(P<0.05). The retinal thickness and perioptic RNFL thickness of contralateral non-amblyopic children in experimental group were thinner than those in control group, but there were no significant differences in most of them(P>0.05).CONCLUSIONS: There are differences in the retinal thickness of the macula and perioptic RNFL in the amblyopic eye and the contralateral non-amblyopic eye of monocular anisometropic amblyopic children compared with normal eyes, and the contralateral non-amblyopic eye is not completely equal to the normal eye.
