Objective:Based on the cost-effectiveness,it aimed to assess the health benefits amd economic value of screening,di-agnosis,treatment,and optimal delicacy management of liver disease in hepatocellular carcinoma(HCC)patients.Methods:A Deci-sion tree-Markov model was developed to compare the cost-effectiveness of HCC screening and long-term surveillance versus no screening in population at risk from the health care system perspective.Results:It is found that HCC screening was a cost-effective approach compared to no screening(Incremental Cost-Effectiveness Ratio[ICER]:17 790 yuan/QALY).Scenario analyses suggested that initiating HCC screening at the age of 40,as recommended by clinical guidelines,and implementing long-term surveillance based on risk stratification were more cost-effective.Conclusions:For the implementation of HCC screening programs,attention should be paid to improving participation and compliance among the population at risk,incorporating advanced screening methods,improving management efficiency with digital tools,and introducing innovative payment methods to reduce economic burden.

Objective:To explore the antitumor effect of ADU-S100/doxorubicin in situ vaccine on diffuse large B-cell lymphoma (DLBCL) and its mechanism.Methods:The 6-week-old female BALB/c mice were selected, and the bilateral murine subcutaneous B-cell lymphoma model was established with murine B-cell lymphoma A20 cells. The subcutaneous tumor-bearing mice were randomly divided into untreated group (without treatment), ADU-S100 in situ vaccine treatment group (intratumoral injection of interferon gene stimulating factor agonist ADU-S100), doxorubicin in situ vaccine treatment group (intratumoral injection of doxorubicin), and ADU-S100/doxorubicin in situ vaccine treatment group (intratumoral injection of ADU-S100 and doxorubicin) by using random number table method, with 5 mice in each group. The right tumors of the bilateral subcutaneous tumor-bearing mice were defined as proximal tumors, and the left tumors of the bilateral subcutaneous tumor-bearing mice were defined as distal tumors. Only the proximal tumors were treated via the intratumoral route, and the distal tumors were not treated. On day 23 after tumor inoculation, the percentages of CD11c + dendritic cells (DC), CD8 + CD11c + DC and CD80 + CD11c + DC in the spleen of mice in each group were detected by flow cytometry. The splenocytes of mice in each group were stimulated with A20 tumor cell lysate in vitro, the percentages of 5'-ethynyl-2'-deoxyuridine-positive (EdU +) cells and tumor necrosis factor-α-positive (TNF-α +) cells in CD8 + T cells in each in situ vaccine treatment group were detected by flow cytometry, and the killing effect of cytotoxic T lymphocyte (CTL) in each group was measured by using the lactate dehydrogenase (LDH) cytotoxicity assay kit. The mice treated with ADU-S100/doxorubicin in situ vaccine were intraperitoneally injected with anti-mouse CD8α (clone 53-6.7) mAb or isotype control on days 7, 12 and 17 after tumor inoculation to eliminate CD8 + cells. On day 23 after tumor inoculation, the proximal and distal tumor volumes of mice in the ADU-S100/doxorubicin in situ vaccine combined with anti-mouse CD8α (clone 53-6.7) mAb or isotype control treatment group were measured, the percentages of CD8 + T cells and CD8 + CD11c + DC in the spleen of tumor-bearing mice in these two groups were detected by flow cytometry, and the infiltration of CD8 + T cells in the tumor tissues from these two groups was detected by immunohistochemistry (IHC) staining. Results:On days 11, 14, 17, 20 and 23 after tumor inoculation, the proximal and distal tumor volumes of mice in each treated group were lower than those in the untreated group (all P < 0.05). The proportions of CD11c + DC in the spleen of the untreated group, ADU-S100 in situ vaccine treatment group, doxorubicin in situ vaccine treatment group and ADU-S100/doxorubicin in situ vaccine treatment group were (4.92±0.63)%, (7.54±0.84)%, (7.45±0.86)% and (11.63±0.85)%, respectively, and the difference was statistically significant ( F = 72.30, P < 0.001); the proportions of CD8 + CD11c + DC were (1.36±0.34)%, (4.02±0.43)%, (4.22±0.61)% and (6.11±0.73)%, respectively, and the difference was statistically significant ( F = 76.09, P < 0.001); the proportions of CD80 + CD11c + DC were (0.51±0.24)%, (1.69±0.23)%, (1.82±0.25)% and (4.09±0.39)%, respectively, and the difference was statistically significant ( F = 167.40, P < 0.001). The CTL responses and the proportion of EdU + cells and TNF-α + cells in CD8 + T cells in each in situ vaccine treatment group were higher than those in the untreated group (all P < 0.05). Furthermore, the enhanced CTL responses and the increased proportion of EdU + cells and TNF-α + cells in CD8 + T cells were observed in the ADU-S100/doxorubicin in situ vaccine treatment group as compared to the ADU-S100 in situ vaccine treatment group and doxorubicin in situ vaccine treatment group (all P < 0.05). The proportions of CD8 + T cells and CD8 + CD11c + DC in the spleen of mice treated with ADU-S100/doxorubicin in situ vaccine and anti-mouse CD8α mAb were lower than those in ADU-S100/doxorubicin in situ vaccine and isotype control group (both P < 0.05) and both proximal and distal tumor volumes of mice treated with ADU-S100/doxorubicin in situ vaccine and anti-mouse CD8α mAb were larger than those in ADU-S100/doxorubicin in situ vaccine and isotype control group (both P < 0.05). Conclusions:ADU-S100/doxorubicin in situ vaccine can induce profound regression of proximal tumors in bilateral murine subcutaneous B-cell lymphoma model and generate systemic immune responses capable of partially inhibiting distant tumor growth, and the antitumor efficacy of ADU-S100/doxorubicin in situ vaccine may require CD8 + CD11c + DC-mediated CD8 + T cell immune responses.

Objective:To explore the early predictive value of umbilical cord blood S100β protein and lactate combined with amplitude integrated electroencephalogram（aEEG）in small for gestational age（SGA）preterm infants with brain injury.Methods:One hundred and six cases of SGA preterm infants were enrolled in this study in Neonatology Department of Inner Mongolia People's Hospital from January 2019 to December 2021. Umbilical cord blood serum S100β protein and lactate at birth of All SGA preterm infants were tested，and aEEG was monitored at 6h and 72 h after birth，corrected gestational age of 32 weeks and 37 weeks. According to the diagnostic criteria of brain injury in preterm infants，SGA preterm infants were divided into brain injury group（45 cases）and non-brain injury group（61 cases），and compared the differences of S100β protein，lactate and the designated time aEEG between the two groups.SGA preterm infants with brain injury were further divided into symmetrical group（28 cases）and non-symmetrical group（15 cases）. The differences of umbilical cord blood S100β protein and lactate level between the two groups were compared，and the diagnostic value in different types of SGA preterm infants with brain injury was also compared.Results:SGA preterm infants in the brain injury group had significantly higher levels of umbilical cord blood S100β protein［（0.826±0.218）μg/L vs（0.397±0.196）μg/L， t=8.316， P<0.05］and lactate［（8.5±1.3）mmol/L vs（3.8±0.9）mmol/L， t=3.281， P<0.05］than those in non-brain injury group.Symmetric SGA group had higher level of S100β protein than the asymmetric SGA group［（0.924±0.205）μg/L vs（0.438±0.196）μg/L， t=5.734， P<0.05］.But there was no statistically significant difference in lactate levels［（5.6±1.4）mmol/L vs（3.9±1.2）mmol/L， t=0.932， P>0.05］between symmetric SGA group and asymmetric SGA group. The abnormal rates of aEEG in brain injury group and non-brain injury group were respectively 100%（45/45）vs 22.95%（14/61）at 6 h after birth，95.56%（43/45）vs 16.39%（10/61）at 72 h after birth，62.22%（28/45）vs 6.56%（4/61）at 32 weeks of corrected gestational age，22.22%（10/45）vs 3.28%（2/61）at 37 weeks of corrected gestational age. The abnormal rate of brain injury group was higher than the non-brain injury group in the same nodal time，and the differences were statistically significant（ χ 2 value respectively 62.292，64.913，38.074，9.257，all P<0.05）. Conclusion:There were significant value in umbilical cord blood S100β protein，lactate level and aEEG monitoring in the early diagnosis in preterm infants SGA with brain injury. The combination of the three might be more helpful for the early diagnosis and timely treatment of brain injury in SGA preterm infants.

Objective To investigate the expression of zinc finger protein 382(ZNF382)in diffuse large B-cell lymphoma(DLBCL)tissue and its relationship with clinical pathological characteristics and prognosis of DLBCL patients.Methods A total of 57 DLBCL patients admitted to the Department of Hematology,Luoyang Central Hospital from January 2014 to December 2018 were selected as the research subjects.The biopsy pathological specimens and clinical data of DLBCL patients were collected;another 20 patients of reactive proliferative lymph node tissue preserved in the Department of Pathology,Luoyang Central Hospital were taken as the control group.The expression of ZNF382 in DLBCL tissue and reactive proliferative lymph node tissue was detected by En vision two-step method.The difference of ZNF382 expression was compared between DLBCL tissue and reactive proliferative lymph node tissue.The correlations of ZNF382 expression with the clinical features such as age,gender,primary tumor site,Ann Arbor stage,international prognostic index(IPI)score,Hans typing,B-symptoms,bone marrow infiltration,giant masses,Eastern Cooperative Oncology Group(ECOG)score,β2-microglobulin(β2-MG),serum lactate dehydrogenase(LDH),Ki67,and chemotherapy regimen of DLBCL patients were analyzed by univariate analysis;the survival curve was drawed by Kaplan Meier method,and the univariate and multivariate survival analysis were performed by log-rank tests and Cox proportional risk regression models.Results The expression level of ZNF382 in DLBCL tissue was significantly lower than that in reactive proliferative lymph node tissue(Z=-5.056,P＜0.01).The expression level of ZNF382 was correlated with IPI score,Ann Arbor stage,Hans typing,B-symptoms,bone marrow infiltration and giant masses of DLBCL patients(P＜0.05);the expression level of ZNF382 was not associated to gender,age,primary site,ECOG score,β2-MG,serum LDH,Ki67,and whether the chemotherapy regimen combined with rituximab or not of DLBCL patients(P＞0.05).Among the 57 DLBCL patients,the treatment was effective in 36 patients(63.20％)and ineffective in 21 patients(36.80％);the expression level of ZNF382 in tumor tissue of DLBCL patients with effective treatment was significantly higher than that of DLBCL patients with ineffective treatment(Z=-2.895,P＜0.05).The 2-year event free survival rate of DLBCL patients in the ZNF382 high expression group was significantly higher than that in the ZNF382 low expression group(x2=17.955,P＜0.001).The results of univariate survival analysis showed that female,primary lymph nodes,B-symptoms,bone marrow infiltration,giant masses,IPI score≥3,elevated β2-MG,Ki67＞70％,non-germinal center B-cell-like lymphoma,Ann Arbor stageⅢ-Ⅳ and low expression of ZNF382 were risk factors for poor prognosis in DLBCL patients(P＜0.05).The results of multivariate analysis showed that primary lymph nodes,Ann Arbor stage Ⅲ-Ⅳ and low expression of ZNF382 were independent influencing factors for poor prognosis in DLBCL patients(P＜0.05).Conclusion ZNF382 protein is low expressed in the tumor tissues of DLBCL patients,which is closely related to the occurrence,development and prognosis of DLBCL;and it can be used as an indicator for evaluating the prognosis of DLBCL.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

Children's sleep health runs through the entire process of children's growth and development and is of great significance.Sleep disorders are one of the important problems affecting children's grow，development and growth health.The number of pediatric patients with sleep disorders is on the rise year by year.Current studies show that the disturbance of children's sleep homeostasis is usually accompanied by the increase of neuroendocrine system activities，the activation of immune system，metabolic disorders，etc，lead to the corresponding hormones（such as cortisol），inflammatory factors，metabolic substances and other homeostasis changes，mutual influence，forming a vicious cycle.In addition，the relationship between genetic factors and sleep is also increasingly concerned.This article reviews the mechanisms，influencing factors and research progress of children's sleep health and sleep disorders，aiming to provide a reference for clinical intervention in children′s sleep problems.

Acute respiratory distress syndrome is one of the common complications of sepsis syndrome, belonging to the "Chuan syndrome", "Baochuan", and "Chuantuo" in the TCM field, and the disease is mainly located in the lung. The main etiology and pathogenesis of sepsis syndrome is deficient healthy qi and blood stasis with toxin blocking collaterals. Blood stasis and toxin invade the lung, causing heat and toxin to burn the body fluid in the blood. Blood viscosity and poor circulation lead to the accumulation of blood stasis and toxin in the lung. Acute deficiency syndrome, heat toxin damaging qi, heat toxin burning body fluid deficiency with little ability to dissipate qi, resulting in deficiency of healthy qi, inability to regulate breathing, inability to consolidate body fluid, inability to promote blood circulation, causing phlegm, dampness, and blood stasis blocking the lung. This disease is characterized by blood stasis with toxin blocking collaterals, deficient lung qi, and obstruction of lung qi caused by phlegm, water, dampness, and blood stasis. Therefore, blood stasis with toxin blocking collaterals, as well as deficient healthy qi are TCM pathogenesis of ARDS with sepsis syndrome.

Oral bacteria are associated with a variety of oral diseases such as caries,periodontal disease and oral cancer.Some patho-genic bacteria also play an important role in the occurrence and development of systemic diseases.The rapid identification of bacterial pathogens helps the diagnosis and precise treatment of oral diseases.Raman spectroscopy is a simple,rapid and non-invasive novel de-tection technique that can provide abundant and detailed bacterial information and can rapidly identify bacteria,but the application of this technique in oral clinical settings is still relatively rare and needs further exploration.This paper summarizes the research progress of Raman spectroscopy in the identification of oral bacteria and discusses the prospects and challenges of its clinical application.

Objective:To explore the standardization of totally implantable venous power port of nursing process in CT enhancement and application effect of contrast medium injection, so as to provide a safer and more efficient way for contrast medium injection in CT enhanced examination for patients with malignant tumors.Methods:A non-randomized prospective study was conducted, 358 patients with malignant tumors were selected in Sun Yat-sen Memorial Hospital, Sun Yat-sen University who underwent CT enhanced examination from August 1, 2022 to July 31, 2023, 179 patients who had been implanted totally implantable venous power port were selected as the experimental group, and the standardized nursing procedure was given. The other 179 patients were the control group, using radiology routine high-pressure intravenous indwelling needle as the contrast medium access, with routine peripheral venous nursing process. The incidence of contrast medium extravasation during CT enhanced examination was observed and compared between the two groups.Results:All the patients were included. There were 85 males and 94 females, aged (55.50±11.72) years old in the control group. There were 83 males and 96 females, aged (54.50±12.24) years old in the experimental group. The incidence of contrast medium extravasation was 0 in the experimental group and 3.35%(6/179) in the control group. The difference between the two groups was statistically significant (Fisher exact probability, P<0.05). Conclusions:The application of standardized nursing procedure of totally implantable venous power port to the injection of contrast medium in CT enhanced examination of malignant tumor patients, can significantly reduce the incidence of contrast medium extravasation.
