Objective:To discuss the optimal doping concentration of vanadium(V)and silicon(Si)co-doped TiO? coating(V-Si TiO?)formed on titanium surface by electrochemical treatment,to evaluate its antibacterial effect under visible light irradiation,and to clarify its visible light response mechanism.Methods:The medical pure titanium sheets were subjected to micro-arc oxidation followed by high-temperature calcination,and V-Si TiO2 coatings with different doping concentrations were prepared by adjusting the ratio of V to Si in the electrolyte.The experiment was divided into 1V:10Si(V5Si50)group,2V:10Si(V10Si50)group,and 3V:10Si(V15Si50)group;control group was set up(contains only bacterial culture medium).The optimal doping concentration was screened based on comprehensive evaluation of surface morphology,ion release,photocatalytic ability,and biocompatibility;cell counting kit-8(CCK-8)method was used to detect the proliferation activities and the survival rates of the cells in various group.Subsequently,the optimized coating was characterized and compared by scanning electron microscope(SEM),atomic force microscopy(AFM),digital eddy current coating thickness gauge,X-ray diffraction(XRD),X-ray photoelectron spectroscope(XPS),and ultraviolet-visible absorption spectroscopy(UV-vis).The experiment was divided into PT group(blank control),PEO group(no element doping),V10 group(V doping),Si50 group(Si doping),and V10Si50 group(2V:10Si).The ability of the coating materials to degrade methylene blue(MB)and generation of reactive oxygen species(ROS)under visible light were detected.For antibacterial experiments,Staphylococcus aureus(S.aureus)and Escherichia coli(E.coli)were used.The colony counts on plates in various groups were recorded after visible light irradiation for 2 h and dark treatment for 2 h,respectively.The ROS levels were detected using 2',7'-dichlorofluorescein diacetate(DCFH-DA)ROS probe.ROS scavenging experiment was performed using the optimal doping concentration V10Si50 group,and the two kinds of bacteria were divided into blank control group,N-acetylcysteine(NAC)group,V10Si50 group,and NAC+V10Si50 group.The colony counts on plates in various groups were recorded after visible light irradiation for 2 h.Results:The V concentration of 0.01 mol·L?1 and Si concentration of 0.05 mol·L?1 in the electrolyte solution were the optimal doping concentrations for the V-Si TiO? coating.The SEM observation results showed that compared with V5Si50 group and V15Si50 group,the surface pore size of the coating material in V10Si50 group was significantly decreased(P<0.05),and the coating thickness was significantly increased(P<0.05);its crystal structure was mainly anatase type,and the MB degradation rate of the coating material in V10Si50 group after 9 h of visible light catalysis was significantly increased(P<0.05).Compared with control group,the cell proliferation activity and cell survival rate in V10Si50 group were significantly increased at 1,2,and 4 d of cell culture(P<0.05);at 2 and 4 d of cell culture,the cell proliferation activity and cell survival rate in V5Si50 group and V15Si50 group were significantly decreased(P<0.05).Compared with PT,PEO,and Si50 groups,the colony counts of two kinds of the bacteria in V10 group and V10Si50 group after visible light irradiation for 2 h were significantly decreased(P<0.05).Compared with PT group and PEO group,the ROS levels in two kinds of the bacteria in V10Si50 group after 2 h of irradiation were significantly increased(P<0.05).Compared with V10Si50 group,the colony counts of two kinds of the bacteria in NAC+V10Si50 group were significantly increased(P<0.05).Conclusion:A reasonably loaded V-Si TiO? coating material(V10Si50)was screened out,which maintained good biological activity and significantly enhanced the antibacterial effect under visible light irradiation.

Objective To investigate the status quo of health management behaviors in elderly patients with type 2 diabetes mellitus(T2DM)complicating chronic complications and the influencing factors based on health ecology theory.Methods The convenience sampling method was used to select elderly patients with T2DM complicating chronic complications in the Shanghai City from January to July 2022 as the respondents.Based on the health ecology theory,the five aspects of personality traits,psychological and behavioral traits,family and community interpersonal networks,living and working conditions and policy environment were in-vestigated.The Pearson correlation coefficient was used to analyze the correlation of various variables.The hi-erarchical linear regression was used to analyze the influencing factors of health management behaviors in eld-erly patients with T2DM complicating chronic complications.Results A total of 272 questionnaires were dis-tributed and 264 valid questionnaires were recovered,with an effective recovery rate of 97.06％(264/272).There were statistically significant differences in DSMB-Oscores among the patients with different chronic complications number,sleep quality,per capita monthly household income and medical payment methods(P＜0.05).The DSMB-Oscore in elderly patients with T2DM complicating chronic complications was positively correlated with HLSCP,DES,PACIC and CIRS scores(P＜0.05),and negatively correlated with the PAID-5 score(P＜0.05).Conclusion The health management behaviors of elderly patients with T2DM complicating chronic complications is jointly affected and acted by many factors,and it is necessary to identify and manage the related influencing factors from different aspects and different levels.

A young male patient was diagnosed with aplastic anemia accompanied by paroxysmal nocturnal hemoglobinuria(PNH),and achieved only partial remission after immunosuppressive therapy.Over the past year,his anemia worsened,leading to transfusion dependence,which was considered to be caused by active he-molysis of PNH.Despite switching to eculizumab treatment,his anemia continued to deteriorate.A detailed medical history revealed chronic periodontal infection,with periodontal pain,purulent discharge,and fever in the past month.Multidisciplinary discussion suggested that chronic odontogenic infection activating the comple-ment system was the primary cause of aggravated PNH hemolysis,and the acute infection affected the efficacy of eculizumab.Based on multidisciplinary consultation,a treatment plan was formulated,including intravenous antibiotics combined with periodontal irrigation and tooth extraction to control odontogenic infection,while con-tinuing regular eculizumab infusion.The patient's symptoms improved,hemoglobin levels rose rapidly,and he was no longer transfusion-dependent.This case provides an empirical reference for addressing difficulties en-countered in the treatment of rare diseases with new drugs through multidisciplinary collaborative diagnosis and treatment.

Objective To observe the value of T2 mapping for quantitatively evaluating the changes of junctional zone and outer myometrium caused by endometrial fibrosis.Methods A total of 73 infertility patients with endometrial fibrosis confirmed by hysteroscopy(disease group)and 33 healthy women of childbearing age(control group)were prospectively enrolled,and MR examinations were performed at the late proliferative phase of endometrium.The thickness and T2 value of junctional zone,T2 value of outer myometrium on anterior,posterior and fundus wall of midsagittal corpus uteri were measured,and the mean value of the above measurements on the three walls were calculated.Receiver operating characteristic curves were constructed,the areas under the curves(AUC)were calculated to explore the efficacy of those with significant difference among the mean thickness and the mean T2 value of junctional zone,the mean T2 value of outer myometrium and their combination for evaluating endometrial fibrosis.Results The thickness and T2 value of anterior wall,posterior wall,fundus wall and the mean junctional zone in disease group were all significantly higher than those in control group(all P＜0.001).No significant difference of T2 value of anterior wall,posterior wall,fundus wall nor the mean outer myometrium was found between groups(all P＞0.05).The mean thickness and the mean T2 value of junctional zone and their combination could be used to effectively evaluate endometrial fibrosis,with AUC of 0.839,0.822 and 0.922,respectively,and their combination had the best performance(both P＜0.01).Conclusion T2 mapping could be used to quantitatively evaluate the injury of junctional zone caused by endometrial fibrosis.

Objective:To explore the pathogenic mechanism of a child with Waardenburg syndrome type 4C due to a c. 661_664dup (p.P222Lfs*60) variant of SOX10 gene through in vitro experiments. Methods:A child diagnosed at the Handan First Hospital was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples were collected from the child and his parents. Following extraction of genomic DNA, trio-whole exome sequencing was carried out. Pathogenicity of candidate variant was determined by bioinformatic analysis and reference to the guidelines from the American College of Medical Genetics and Genomics (ACMG). Candidate variant was verified by Sanger sequencing. Expression plasmids of wild-type SOX10 and the c. 661_664dup (p.P222Lfs*60) variant were constructed and transiently transfected into 293T cells to determine the expression at the RNA and protein levels. The 293T cells transiently transfected with the wild-type/mutant SOX10 were treated with 10 μg/mL cycloheximide (CHX) for 0, 4, 8, 24 h, respectively, and the degradation rate of target protein was detected by Western blotting assay. This study has been approved by the Ethics Committe of Handan First Hospital(Ethics No.HDYY-LW-25053). Results:The child was found to harbor a heterozygous c. 661_664dup (p.P222Lfs*60) variant of the SOX10 gene, which was unreported previously. The variant did not significantly alter the expression of SOX10 at the mRNA level but the protein level. After the CHX treatment, the degradation of mutant SOX10 protein had slowed down. Conclusion:The mutant SOX10 may affect the expression of downstream genes by affecting the degradation rate of its protein product.

Objective To explore the risk factors of cardiomyopathy in patients with diabetes and their correlations with the levels of serum fork head box protein O1(FOXO1),growth differentiation factor 11(GDF11),and matrix metalloproteinase-3(MMP3).Methods 200 patients with diabetes complicated with cardiomyopathy and 200 patients with simple diabetes admitted to the People's Hospital of Xinjiang Uygur Autonomous Region from September 2023 to April 2025 were selected to detect serum FOXO1,GDF11 and MMP3 levels,analyze their correlation with cardiac function parameters,screen risk factors through multifactor logistic regression,construct a nomogram model and a receiver operating characteristic(ROC)curve,and evaluate the diagnostic value.Results The duration of diabetes cardiomyopathy group≥10 years,the expression rate of reactive oxygen species(ROS)≥90%,the insulin resistance index and the levels of FOXO1 and MMP3 were significantly higher than those in the simple diabetes group(P<0.05),and the level of GDF11 was lower than that in the simple diabetes group(P<0.05).FOXO1 and MMP3 were positively correlated with E/e'and negatively correlated with LVEF and E/A;GDF11 was negatively correlated with E/e'and positively correlated with LVEF and E/A(P<0.05).The nomogram model showed that the weights of the influencing factors were GDF11,FOXO1,insulin resistance index,MMP3,ROS expression rate,and the course of diabetes.The model calibration was good(χ2=7.336,P=0.719).The combined diagnostic AUC of FOXO1,GDF11,and MMP3 was 0.950,which was better than that of a single indicator(P<0.05).Conclusion GDF11,FOXO1,Insulin resistance index,MMP3,ROS expression rate and the course of diabetes are risk factors for diabetes cardiomyopathy,and the combination of the three is of high diagnostic value.

Background and aims:Clinical data regarding patients with chronic hepatitis B(CHB)after Omicron BA.5 infection are currently limited.This study aimed to assess the clinical characteristics of patients with CHB and Omicron BA.5 infection in South China.Methods:This retrospective study was conducted from January to March 2023 in a cohort of 485 healthy individuals and 553 patients with CHB.Clinical features,encompassing COVID-19-related symptoms,levels of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)antibodies,vaccination status,liver functions,and virological markers of hepatitis B virus(HBV)infection were measured.Results:COVID-19-related symptom patterns were similar in both groups,except for fever,which was notably less prevalent(85.4％vs.90.4％,P=0.047)among patients with CHB who experienced a significantly shorter duration of fever(median 2.2(25th-75th percentile,1.0-3.0)days vs.2.3(1.0-3.0)days,P=0.048)and a shorter time for symptom relief(9.2(5.0-14.0)vs.11.1(5.0-14.0)days,P=0.015).The levels of SARS-CoV-2 antibodies were comparable between the two groups but increased after booster vaccinations.In patients with CHB,globulin(GLB)and hepatitis B envelope antibody levels were significantly increased after Omicron BA.5 infection,regardless of nucleos(t)ide analog regimens comparing entecavir(ETV)with tenofovir(TFV).Patients with CHB treated with TFV had significantly higher levels of SARS-CoV-2 antibodies than those treated with ETV(1065.1(346.9-1188.5)COI vs.765.5(24.5-1119.1)COI,P=0.025).Conclusions:No significant exacerbation of COVID-19 symptoms was observed in conjunction with the efficacy of COVID-19 booster vaccinations.There were no notable alterations in liver functions except for GLB.HBV reactivation,as evidenced by increased HBV DNA,was observed among patients with CHB after Omicron BA.5 infection.These changes were not affected by ETV versus TFV administration;however,TFV resulted in a significant increase in SARS-CoV-2 antibody levels.Further studies are required to improve care and therapeutics for patients with CHB who contracted COVID-19.

Objective To observe the levels of serum NOD-like receptor thermal protein domain associated protein 3(NLRP3),cysteine protease 1(Caspase-1),and interleukin 1β(IL-1β)in patients with systemic lupus erythematosus(SLE)and to explore their correlation with traditional Chinese medicine(TCM)syndrome types,thus to assess the significance of NLRP3,Caspase-1 and IL-1β in TCM syndrome differentiation.Methods A total of 110 cases of SLE patients who met the inclusion criteria and 30 cases of healthy physical examinee from Linhai Hospital of Traditional Chinese Medicine during October 2020 to March 2024 were enrolled into the study.The serum NLRP3,Caspase-1,IL-1β levels of the two groups were compared,and the correlation between serum NLRP3,Caspase-1,IL-1β levels and the Systemic Lupus Erythematosus Disease Activity Index(SLEDAI)scores was analyzed.Moreover,the distribution of the TCM syndrome types in 110 cases of SLE patients was investigated and then the correlation between TCM syndrome types and serum NLRP3,Caspase-1,and IL-1β levels in SLE patients was explored.Results(1)The serum NLRP3 and Caspase-1 levels of patients in SLE group were lower than those of healthy control group,and the serum IL-1β level was higher than that of healthy control group,and the differences were statistically significant(P<0.05).Spearman's correlation analysis showed that the SLEDAI score was negatively correlated with both of NLRP3 and Caspase-1(r=-0.854,-0.599,P<0.01),and SLEDAI score was positively correlated with IL-1β(r=0.584,P<0.01).(2)The TCM syndrome types in 110 cases of SLE patients ranking in descending order were as follows:excessive heat toxin syndrome(33.64%)>yang deficiency of spleen and kidney syndrome(25.45%)>internal heat due to yin deficiency syndrome(24.55%)>yin deficiency of liver and kidney syndrome(16.36%).(3)The serum NLRP3 and Caspase-1 levels were in ascending order while the serum IL-1β level was in descending order in SLE patients with the TCM syndrome types of excessive heat toxin syndrome,internal heat due to yin deficiency syndrome,yang deficiency of spleen and kidney syndrome,yin deficiency of liver and kidney syndrome,respectively.And the differences were all statistically significant(P<0.05).(4)The results of multivariate logistic regression analysis showed that serum NLRP3 and caspase-1 levels were negatively correlated with syndromes of yin deficiency of liver and kidney,yang deficiency of spleen and kidney,internal heat due to yin deficiency,and excessive heat toxin(P<0.05 or P<0.01),while serum IL-1β level was positively correlated with the above syndromes(P<0.05).Conclusion Serum NLRP3 and Caspase-1 levels in SLE patients are negatively correlated with the disease activity,and serum IL-1β level is positively correlated with the disease activity.There is a certain correlation between TCM syndrome types and NLRP3,Caspase-1 and IL-1β levels in SLE patients,indicating that NLRP3,Caspase-1 and IL-1β may be the potential biological indicators for TCM syndrome differentiation of SLE.
