Over the past three decades， China has made significant progress in the prevention and control of viral hepatitis， and the incidence rates of new-onset pediatric hepatitis B virus infections and acute viral hepatitis in the population have reduced to a relatively low level； however， there is still a heavy disease burden of chronic viral hepatitis in China， which severely affects the health status of the population. This study systematically summarizes the achievements of viral hepatitis prevention and control in China， analyzes existing problems and challenges， and proposes comprehensive prevention and control strategies and measures to eliminate viral hepatitis as a public health threat based on the national conditions of China， in order to provide a reference for related departments in China on how to achieve the action targets for eliminating viral hepatitis as a public health threat by 2030.

Objective To investigate the therapeutic effectiveness of ozone combined with low-temperature plasma coagulation therapy on patients with cervical spondylotic radiculopathy and its influence on inflammatory responses.Methods Ozone in combination with low-temperature plasma radio-frequency coagulation was applied to 75 patients with cervical spondylotic radiculopathy in Pain Medicine Department of Capital Medical University Affiliated Beijing Anzhen Hospital from May 2022 to May 2023.Pain scores were assessed using Visual Analog Scale(VAS)and Neck Disability Index(NDI)before and two weeks after treatment.Enzyme-linked immunosor-bent assay(ELISA)was used to analyze the level of tumor necrosis factor-alpha(TNF-α),interleukin-6(IL-6)and interferon-gamma(IFN-γ)before and two weeks after treatment.Results After treatment with ozone plus low-temperature plasma radiofrequency,VAS and NDI scores showed a significant decrease[VAS:5.36(4,7)vs.1.32(1,2),P＜0.000 1;NDI:32.72(24,70)vs.7.62(3.55,8.9),P＜0.000 1].Two weeks after surgical intervention,there was an effective reduction in the level of IL-6,TNF-αand IFN-γ alleviating the inflammatory re-sponse[IL-6:4.33(2.51,5.04)vs.3.49(2.08,4.43),P＜0.05;TNF-α:1.95(1.41,2.21)vs.1.61(1.02,2.03),P＜0.05;IFN-γ:1.84(1.18,2.47)vs.1.55(0.76,2.09),P＜0.05].Conclusions This Ozone combined with low-temperature plasma radiofrequency ablation is an effective technology for treatment of cer-vical spondylotic radiculopathy.

Objective To explore the correlation of serum matrix metalloproteinase-9(MMP-9)and heat shock protein-47(HSP-47)levels with prognosis in patients with acute cerebral hemorrhage.Methods One hundred and forty-five patients with acute cerebral hemorrhage attending our hospital from March 2018 to May 2022 were selected,and assigned into good prognosis group(n=80)and poor prognosis group(n=65)according to their postoperative prognosis.General information of patients was recorded.The early morning of the day after admission fasting peripheral venous blood samples were collected for the detection of serum MMP-9 and HSP47 levels.Multivariate Logistic regression analysis was conducted to screen the risk factors affecting poor prognosis in patients with acute cerebral hemorrhage,and the predictive value of serum MMP-9 and HSP47 levels on prognosis of patients with acute cerebral hemorrhage was evaluated by plotting ROC curve.Results Statistical difference was found in shape and volume of hematoma between two groups(P＜0.05).Serum MMP-9 and HSP47 levels in poor prognosis group were higher than that in good prognosis group(P＜0.05).Multivariate Logistic regression analysis denoted that duration of surgery,hematoma shape,hematoma volume,serum MMP-9 and HSP47 levels were all risk factors for poor prognosis in patients with acute cerebral hemorrhage(P＜0.05).Patients with the time of onset to surgery＞24 hours irregular shaped hematoma,large hematoma volume,and elevated serum levels of MMP-9 and HSP47 suffered a high risk of poor prognosis.ROC curve analysis demonstrated that AUC of serum MMP-9 and HSP47 levels for predicting the postoperative prognosis of patients with acute cerebral haemorrhage were 0.718 and 0.827,with a sensitivity of 81.5％and 80.0％,and a specificity of 50.0％and 81.2％,respectively.The AUC,sensitivity and specificity of combined detection of serum MMP-9 and HSP47 for prognosis prediction were 0.891,86.2％and 85.0％.Conclusion Serum MMP-9 and HSP47 levels are elevated in patients with poor prognosis after acute cerebral haemorrhage,and irregular shaped hematoma,hematoma volume,and serum MMP-9 and HSP47 levels are risk factors for poor prognosis after acute cerebral haemorrhage.Furthermore,serum MMP-9 and HSP47 are of great predictive value for the prognosis of patients with acute cerebral haemorrhage,and the predictive efficacy of combined detection of the two is better than that of separate test.

Objective To explore the guiding value of thromboelastography(TEG)in the formulation of personalized anticoagulation regimen after knee arthroscopy.Methods A total of 50 patients who underwent knee arthroscopy in our hos-pital from April to August 2023 were randomly divided into two groups.Twenty-seven patients with routine anticoagulation were selected as the control group,and 23 patients with personalized anticoagulation were selected as the experimental group.Conventional anticoagulation was a prophylactic dose of low molecular weight heparin calcium(LMWHC)selected according to body weight,once a day to 7 days after surgery.Personalized anticoagulation was performed according to the prophylactic dose of LMWHC until postoperative day 3.On postoperative day 3,LMWHC was changed to aspirin according to the TEG return index(MA>70 mm,α Angle>72°,K value<1 min),and the initial prophylactic dose was 100 mg/d.LMWHC was changed to rivaroxaban when R<5 min,and the prophylactic dose was 10 mg/d until postoperative day 7.Pa-tients with hypocoagulation or subcutaneous ecchymosis stopped the drug first,and if it was further aggravated,component blood transfusion was performed according to the TEG results.The difference of Caprini score in perioperative period,the correlation between TEG and CCT on postoperative day 1,and the accuracy of predicting thrombosis on postoperative day 7 were compared between the two groups using the receiver operating characteristic curve(ROC).Results There was a sig-nificant difference in Caprini score between the two groups at 7 days after operation(P<0.05),suggesting that the adjust-ment of anticoagulant drugs in the experimental group was effective at 3 days after operation.Pearson correlation evaluation showed that there was a strong positive correlation between maximum coagulation intensity(MA)in TEG and platelet(Plt)in CCT at day 1 after surgery(P<0.05).Thrombosis was found in the control group at 7 days after operation,all of which were CMVT and disappeared after therapeutic antithrombotic therapy.MA was included in the ROC curve for model analysis.The area under the ROC curve(AUC)of the control group was 0.819,and the AUC of the experimental group was 0.508.It was found that the control group model had higher accuracy in predicting the formation of CMVT.Conclusion Individu-alized anticoagulation under TEG monitoring can effectively reduce the occurrence of CMVT after knee arthroscopy,which has guiding value for anticoagulation and thrombosis prevention.

Objective To summarize the clinical data of macrophage activation syndrome (MAS) in adult-onset Still's disease (AOSD) patients and provide evidence for clinical diagnosis and treatment. Methods We retrospectively reviewed the clinical data of AOSD with MAS patients in the First Affiliated Hospital of Zhengzhou University from January 2012 to August 2018, and compared with patients with AOSD alone. Data were analyzed by t-test, Mann-Whitney U test, x2 test or Fisher exact test. Results A total of 14 AOSD with MAS patients were enrolled, accounting for 7.6％(14/185) of AOSD patients at the same period, including 2 males and 12 females. The median duration of AOSD in MAS was 1.3 (0.25, 4) months. Compared with the AOSD group, the age of onset was younger in the MAS group (t=-2.038, P=0.037), and the proportion of splenomegaly (t=9.020, P=0.003), pericardial effusion (t=8.663, P=0.003), pleural effusion (t=4.754, P=0.029) was higher. The white blood cell count (t=-4.171, P<0.01), hemoglobin level (t=-2.661, P=0.008), platelet count (t=-5.672, P<0.01), neutrophil count (t=-5.082, P<0.01), albumin (t=-3.426, P<0.01), fibrinogen (t=-5.986, P<0.01), ESR (t=-2.941, P=0.003), CRP (t=-2.014, P=0.044) was significantly decreased, ALT (t=-3.227, P<0.01), AST (t=-3.105, P=0.002), triglyceride (t=-5.612, P<0.01), ferritin>2000 μg/L (t=7.833, P=0.005) was significantly increased. Fourteen patients with AOSD complicated with MAS were treated with glucocorticosteroids, 5 with methylprednisolone, 8 with cyclosporine A, 8 with intravenous immunoglobulin (IVIG), 2 with etoposide, and 1 with tocilizumab. After treatment, 11 cases recovered and 3 cases died. Conclusion Younger AOSD patients tend to complicated with MAS, especially at the early course of the disease, and splenomegaly occur more frequently clinically compared to patients without MAS. When blood cell count, fibrinogen and ESR decreases, triglyceride and ferritin levels increases in AOSD patients, the occurrence of MAS is indicated. Timely treatment can improve the prognosis of patients.

Objective: To analyze the clinical features of dyslipidemia in patients with primary biliary cholangitis (PBC). Methods: The clinical and laboratory data of 136 PBC patients in Peking Union Medical College Hospital from 2010 to 2016 were retrospectively analyzed.The liver function was compared between patients with normal and abnormal blood lipids. Results: Among 136 PBC patients, 100(74%)had abnormal serum lipids. The incidence of increased cholesterol, low-density lipoprotein and triglyceride was 61%(59/96), 58%(48/83) and 47%(46/97), respectively; while that of reduced HDL-C was 26%(21/82). The incidences of pruritus [26%(26/100) vs. 8%(3/36), χ²=4.93, P=0.032], serum total bilirubin (TBIL) [17.3(12.2, 28.2) μmol/L vs. 14.5 (9.4, 21.1) μmol/L, Z=2.25, P=0.024], direct bilirubin (DBIL)[5. 5 (3.4, 12.4) μmol/L vs. 4.4(2.9, 7.1) μmol/L, Z=2.00, P=0.045], and glutamyl aminotransferase (GGT)[193.0(64.3, 454.8)U/L vs. 105.5(53.5, 179.5)U/L, Z=2.02, P=0.043], alkaline phosphatase(ALP)[183(86, 351)U/L vs. 135(85, 188) U/L, Z=1.98, P=0.048] in PBC patients with dyslipidemia were significantly higher than thosein patients with normal serum lipids.Pearson regression analysis showed that in PBC patients with dyslipidemia, the ALT was positively corrected with TG and TC(r=0.248 and 0.272, P=0.015 and 0.008); ALB was positively correlated with LDL-C(r=0.335, P=0.002); DBIL was positively corrected with HDL-C(r=0.252, P=0.022); TC was positively correlated with ALP and GGT(r=0.313 and 0.346, P=0.002 and 0.001); GGT was positively correlated with LDL-C(r=0.251, P=0.022). Conslusion Increased TC and LDL-C were more common in PBC patients. PBC patients with dyslipidemia have more severe liver damage than the patients with normal serum lipids.
