Objective To explore the application values of different detection methods in monitoring the decline pattern of syphilis-spe-cific antibody in the non-congenital syphilis children.Methods A total of 80 non-congenital syphilis children were included in the study.The serum specimens were collected after birth,and the syphilis-specific antibodies were detected using electrochemilumines-cence immunoassay(ECLIA),western blotting(WB),treponema pallidum particle agglutination assay(TPPA),enzyme-linked im-munosorbent assay(ELISA),and toluidine red unheated serum test(TRUST).Follow-up was conducted every three months until the positive results of ELISA and TRUST turned to negative.Results The results of ECLIA showed that the syphilis-specific antibody lev-els in the non-congenital syphilis children declined to 25％of the level at birth within 2 to 3 months,and the rate of decline was inde-pendent of the initial concentration.WB analysis indicated that the specific IgG bands in non-congenital syphilis children at birth were consistent with those of their mother,and the sequence of specific antibodies decline was as follows:TPN47,TPN15,TPN45,and TPN17.Due to methodological limitations,the absorbance values of ELISA showed no significant change during the first three months after birth when high concentrations of antibodies were present in the samples,but it showed high sensitivity in the detection for the samples with low-concentration of syphilis antibodies.The detection rates of ECLIA,TPPA,and WB were compared by using ELISA as the reference method.At birth,the detection rates of syphilis antibodies were 100％,100％,and 90％,respectively.In 3 months after birth,the detection rates were 100％,100％,and 75％.In 6 months after birth,,they were 100％,46％,and 15％.In 9 months after birth,they were 83％,33％,and 0％.The positive rate of TRUST was 17.5％at birth.and turned to negative in 3 month of follow-up.Conclusion Syphilis specific IgG antibodies may fully transferred to the fetus and decline in a predictable pattern after birth.The comprehensive analysis for the results of the four methods suggested that dynamic detection using ECLIA method could be used to pre-dict the risk of non-congenital syphilis or terminate the follow-up at 3 months,while the seroconversion detected by WB was earlier than that by TPPA,while ELISA required the longest follow-up period.

Objective To investigate the value of cranial CT cisternal grading combined with D-dimer(D-D)and Glasgow Coma Scale(GCS)score in predicting the short-term postoperative prog-nosis of patients with severe traumatic brain injury.Methods A total of 165 patients with severe trau-matic brain injury who were treated in the hospital from January 2019 to May 2024 were selected as study subjects,all underwent craniotomy surgery.Postoperative follow-up was conducted for 3 months to analyze the differences in clinical data and preoperative indicators such as cranial CT cisternal grad-ing,D-D levels,and GCS scores between patients with poor and good prognosis.The value of cranial CT cisternal grading,D-D levels,and GCS scores in predicting short-term postoperative poor prognosis in patients with severe traumatic brain injury was also analyzed.Results Compared with patients with good prognosis,patients with poor prognosis had higher proportion of age,cranial CT cisternal grading of Ⅰ to Ⅱ,D-D levels,and GCS scores＜6(P＜0.05).There were no statistically significant differences in C-reactive protein,prothrombin time,activated partial thromboplastin time,international normalized ratio,total cholesterol,triglycerides,high-density lipoprotein cholesterol,and low-density lipoprotein cholesterol levels between patients with poor and good prognosis(P＞0.05).Cranial CT cisternal grading,D-D levels,and GCS scores were influencing factors for short-term postoperative poor prognosis in patients with severe traumatic brain injury(P＜0.05).The area under the curve for poor prognosis by three indicators in combination was 0.941(95％CI,0.906 to 0.975),which was higher than the area under the curve for the individual predictions of cranial CT cisternal grad-ing,D-D levels,and GCS scores(P＜0.05).Conclusion The influencing factors for short-term postoperative prognosis in patients with severe traumatic brain injury include cranial CT cisternal grading,D-D levels,and GCS scores.The model based on these three indicators has certain appli-cation value in predicting patient prognosis.

Objective To investigate the correlation between maternal serum folic acid(FA),monocyte chemoattractant protein-1(MCP-1),progesterone-induced blocking factor(PIBF)levels and embryonic development cessation in early pregnancy.Methods From December 2021 to December 2023,98 pregnant women with embryonic development cessation in early pregnancy admitted to the Second Hospital of Jingzhou were regarded as the cessation group,and 50 normal early pregnancy pregnant women who underwent pregnancy examinations during the same period were as the control group.General clinical data was collected and analyzed.Enzyme-linked immunosorbent assay(ELISA)was applied to detect serum levels of FA,MCP-1 and PIBF.Multivariate logistic regression was applied to analyze the influencing factors of early pregnancy embryo cessation of development.Receiver operating characteristic(ROC)curve was plotted to analyze the predictive value of serum FA,MCP-1,and PIBF for early embryonic development cessation in pregnancy.Pearson method was applied to analyze the correlation between serum FA,MCP-1,PIBF,progesterone(PROG),estradiol(E2)and β-human chorionic gonadotropin(β-HCG).Results Compared with the control group,the serum FA(9.51±1.21 nmol/L vs 11.32±1.56 nmol/L)and PIBF(295.46±30.22 ng/ml vs 342.14±36.97 ng/ml)levels in the cessation group were greatly reduced,while the serum MCP-1(1.02±0.15 mg/ml vs 0.82±0.11 mg/ml)level was greatly increased,and the differences were statistically significant(t=7.785,8.347,8.229,all P＜0.001).There were great statistical differences in the history of embryonic development cessation(75.64%vs 25.36%),PROG(13.32±1.81 ng/ml vs 23.65±2.74 ng/ml),E2(221.34±25.69 pmol/L vs 298.65±31.64 pmol/L),and β-HCG levels(5 323.62±536.85U/L vs 8 562.31±924.55 U/L)between the two groups(t/χ2=6.548～27.428,all P<0.05).Pregnant women's history of embryonic development cessation and elevated level of MCP-1 were risk factors for embryonic development cessation in early pregnancy(Wald χ2=4.239,4.613,all P<0.05),while elevated levels of β-HCG,FA and PIBF were protective factors for embryonic development cessation in early pregnancy(Wald χ2=4.476,4.423,5.974,all P<0.05).The AUC of FA,MCP-1,PIBF,and their combination in predicting early embryonic development cessation in pregnancy was 0.811,0.805,0.816 and 0.908,respectively.The combined prediction was greatly better than that of individual diagnosis of FA MCP-1,and PIBF(Z=2.749,2.381,1.993,all P<0.05).FA and PIBF were positively correlated with PROG,E2 and β-HCG(r=0.433～0.512,all P<0.05),while MCP-1 was negatively correlated with PROG,E2 and β-HCG(r=-0.432,-0.487,-0.458,all P<0.05).Conclusion The serum levels of FA and PIBF in pregnant women with embryonic development cessation in early pregnancy decrease,while the level of MCP-1 increases.These three factors are all influencing factors for embryonic development cessation in pregnant women,and have certain auxiliary predictive value for embryonic development cessation in early pregnancy.

Objective To detect the expression level of 4-aminobutyrate aminotransferase(ABAT)in bone marrow of patients with myelodysplastic syndrome(MDS),and analyze its influence on clinicopathological features and prognosis of patients.Methods From January 2016 to March 2020,92 patients with MDS and 30 patients with acute myeloid leukemia(AML)from the First Affiliated Hospital of Xingtai Medical College were retrospectively collected.Meanwhile,30 patients with immunothrombocytopenia who did not develop MDS or other clonal diseases of the blood system during a 3-year follow-up were collected as control group.Real-time quantitative fluorescent PCR(qRT-PCR)was used to detect the relative expression level and methylation level of ABAT mRNA of all patients,and the relative expression level and methylation level of ABAT mRNA among different clinical characteristics of MDS patients were compared.Multivariate logistic regression analysis was used to analyze the risk factors affecting the adverse prognosis of MDS.The clinical value of detecting ABAT methylation level in predicting poor prognosis of MDS patients was analyzed by receiver operating characteristic(ROC)curve.Kaplan-Meier method was used to calculate the 3-year survival rate between groups with different ABAT mRNA relative expression levels and methylation levels,and log-rank test was used for their comparison.Results The expression level of ABAT mRNA in MDS group(0.42±0.08)was lower than that in control group(0.56±0.15)and AML group(0.52±0.10),while the methylation level of ABAT(32.51±5.32)was higher than that of AML group(26.21±4.58)and control group(10.25±4.31),and the differences were significant(t=4.251,4.562;10.415,8.326,all P<0.001).The methylation level of ABAT in high-risk patients(42.65±5.32)was higher than that in low-risk patients(25.63±4.16),intermediate-risk-1 patients(30.59±2.51)and intermediate-risk-2 patients(33.25±3.69)by IPSS risk grade,and the differences were significant(t=8.329,7.077,15.874,all P<0.001).Poor Karyotype analysis result[OR(95%CI):4.973(1.524～8.581),P=0.004],high IPSS risk grade[OR(95%CI):8.542(2.365～14.521),P<0.001]and ABAT hypermethylation level[OR(95%CI):6.178(1.589～13.021),P<0.001]were the risk factors affecting the poor prognosis of MDS.The cut-offvalue of ABAT methylation level to predict the poor prognosis of MDS were 30.54,and the area under the curve(AUC),the sensitivity and specificity were 0.92,0.874 and 0.851,respectively.The 3-year survival rate of the high ABAT methylation group(>30.54)was 66.67%,which was lower than that of the low ABAT methylation group(≤30.54)was 93.18%,with significant difference(Log-rank x2=9.814,P=0.002).Conclusion The ABAT methylation levels in MDS bone marrow increase,which is a risk factor affecting the poor prognosis of patients.ABAT basal level>30.54 is expected to become a factors predicting the poor prognosis of patients.

Objective To explore the value of brain MR three-dimensional arterial spin labeling(3D-ASL),diffusion weighted imaging(DWI)combined with MGMT gene detection in the differential diagnosis of postoperative recurrence and pseudoprogression of high-grade glioma.Methods A total of 30 patients with high-grade glioma were selected,and all patients were divided into pseudoprogression group and recurrence group according to pathological results.The differences in average relative cerebral blood flow(rCBF)and average relative apparent diffusion coefficient(rADC)were compared between recurrence groups and pseudoprogression groups.Results The rCBF in the enhanced center and edge areas in the recurrence group was significantly higher than those in the pseudoprogression group,and the rADC was significantly lower than that in the pseudoprogression group,and the difference was statistically significant(P<0.05).There were correlations between the postoperative recurrence and pseudoprogression of high-grade glioma and the promoter situation of methylation of MGMT gene.Conclusion Brain MR 3D-ASL,DWI combined with MGMT gene detection has important clinical value in the differential diagnosis of postoperative recurrence and pseudoprogression of high-grade glioma.

Objective To examine the application effectiveness of dual 8F ultrafine pigtail drainage tubes versus a single 28F large-bore chest tube in single-port thoracoscopic lobectomy/segmentectomy. Methods Clinical data of patients who underwent single-port video-assisted thoracoscopic lobectomy/segmentectomy within our medical group from January 2020 to August 2023 were retrospectively analyzed. They were categorized into two groups based on postoperative drainage methods: a dual 8F ultrafine pigtail tubes group and a single 28F large-bore chest tube group. Comparative analysis was performed on perioperative data for the two groups of patients. Results The dual 8F ultrafine pigtail tubes group comprised of 68 patients, with 41 females and 27 males, and an average age of (54.72±13.34) years, while the single 28F large-bore chest tube group comprised of 80 patients, with 40 females and 40 males, and an average age of (57.60±11.04) years. There were statistical differences between the two groups in terms of postoperative drainage volume on day 1, day 2, and day 3, total postoperative drainage volume, postoperative tube placement time, postoperative pain score at 48 hours, maximum postoperative pain score, postoperative hospital stay, postoperative complications related to drainage tubes, and emergency use of pain-relieving medication after surgery (P＜0.05). Conclusion After single-port thoracoscopic lobectomy/segmentectomy, the application of dual ultrafine 8F pigtail drainage tubes can lead to a reduction in postoperative drainage volume and shorten the duration of postoperative drainage tube placement and hospital stay, thereby decreasing postoperative pain and the frequency of emergency pain-relieving medication. Moreover, it lowers the incidence of drainage tube-related complications. In alignment with current enhanced recovery after surgery principles, this approach is advantageous for postoperative recovery.

Conclusion The integrated disposable devices may be used for SARS-CoV-2 Point-of-Care test(POCT).

ObjectiveTo investigate the effect of shikosin （SHI） on psoriasis （PSO） and explore the underlying mechanism via the cyclic guanosine monophosphate-adenosine monophosphate synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway. MethodHaCaT cells were classified into normal culture（Control）， a mixture of five proinflammatory cytokines（M5）， low-， medium-， and high-dose SHI （L-SHI， M-SHI， and H-SHI， respectively）， and SHI+ADU-S100 groups. The cells in the M5 group were stimulated with 10 μg·L^-1 interleukin （IL）-1α， IL-17， IL-22， tumor necrosis factor （TNF）-α， and oncostatin M （OSM） for 48 h. The cells in the L-SHI， M-SHI， and H-SHI groups were treated with 0.1， 1， 10 μmol·L^-1 SHI， respectively， on the basis of the treatment in the M5 group. The cells in the SHI+ADU-S100 group were treated with 10 μmol·L^-1 STING activator ADU-S100 on the basis of the treatment in the H-SHI group. The methyl thiazolyl tetrazolium （MTT） assay and colony formation assay were employed to examine the effect of SHI on the proliferation of HaCaT cells. The wound healing assay was employed to examine the effect of SHI on the migration of HaCaT cells. Flow cytometry was employed to detect the effect of SHI on the apoptosis of HaCaT cells. Enzyme-linked immunosorbent assay was employed to measure the levels of IL-1β， IL-6， IL-15， IL-23， and interferon-γ （IFN-γ） in HaCaT cells. Western blot was employed to determine the protein levels of cGAS and STING in HaCaT cells. ResultCompared with Control group， the M5 group showed decreased survival rate， colony formation， and would healing rate of HaCaT cells， increased apoptosis rate， elevated levels of IL-1β， IL-6， IL-15， IL-23， and IFN-γ， and up-regulated protein levels of cGAS and STING （P<0.01）. Compared with the M5 group， the L-SHI， M-SHI， and H-SHI groups showed increased survival rate， cell colony formation， and wound healing rate， decreased apoptosis rate， lowered levels of IL-1β， IL-6， IL-15， IL-23， and IFN-γ， and down-regulated protein levels of cGAS and STING （P<0.01）. Compared with the H-SHI group， the SHI+ADU-S100 group showed decreased survival rate， cell colony formation， and wound healing rate， increased apoptosis rate， risen levels of IL-1β， IL-6， IL-15， IL-23， and IFN-γ， and up-regulated protein levels of cGAS and STING （P<0.01）. ConclusionSHI can inhibit the inflammation in the cell model of PSO by inhibiting the cGAS/STING signaling pathway.
