Objective:To summarize the use of Castor stent graft in aortic diseases and to analyze their efficacy.Methods:The clinical data of patients with aortic diseases treated with Castor stent graft from November 2017 to August 2022 in Fujian Provincial Hospital were collected and divided into branched stent group and branched stent co-operative group according to the operation method, and the clinical data of both groups were summarized.Results:A total of 75 cases of aortic disease were treated with Castor stents, and finally 53 cases were classified as branched stent group and 22 cases as branched stent co-operative group. The operations in both groups were successful. The median operative time in the branched stent group was 120(100, 160)min, and the median postoperative hospital stay was 7.0(5.5, 10.5)days.There was no postoperative ischemic stroke, no spinal cord ischemia. One case of new aortic dissection occurred. During follow-up, there was one lost case and two deaths, and the rest did not have endoleak, branch stent stenosis, ischemic stroke or re-intervention. In the branched stent co-operative group, there was one postoperative ischemic stroke, one case of slight stenosis of the left subclavian artery stent during follow-up, the remaining cases had satisfactory postoperative outcomes.Conclusion:Castor stent graft is a safe and effective procedure in the treatment of aortic diseases. And Castor stent graft can be used in combination with other endovascular repair techniques in the treatment of complex aortic diseases, with safe and reliable postoperative outcomes.

Objective:To analyze the whole genome sequence and key site mutations of hepatitis B virus (HBV) in patients with different stages of disease progression, and to understand the relationship between HBV genetic characteristics and disease progression.Methods:Serum samples and basic information of hepatitis B patients with asymptomatic HBV carrier, chronic hepatitis B patients, cirrhosis patients and primary hepatocellular carcinoma patients were collected. Nested PCR was used to amplify the samples to obtain HBV whole gene sequences. Phylogenetic trees were constructed to determine the genotype of the samples, and gene mutations of the samples were analyzed combined with reference sequences of each type.Results:A total of 256 samples were successfully amplified, including 68 asymptomatic HBV carrier patients, 118 CHB patients, 15 LC patients and 55 HCC patients, and five genotypes (B, C, D, I and C/D) were detected. The result of comparative analysis showed that the mutation rate of 56 nucleotide sites was significantly different among the four groups ( P<0.05). In addition to the discovery of C105T, A1762T/G1764A and G1899A and other previously reported key site mutations, the mutation rates of T53A, C1485T and C1628T in newly diagnosed HCC group were significantly higher than those in other groups, and the mutation rates of T2150G and T2151C in asymptomatic HBV infection group were significantly higher than those in other groups. A total of 26 sequences were deleted, mainly distributed in the pre-C and pre-S regions. The deletion mutation rate in the HCC group was significantly higher than that in the other groups. Conclusions:The data of this study indicate that some nucleotide substitution mutations and deletion mutations may be closely related to the occurrence and development of HBV-related diseases, and HCC patients are more likely to have gene mutations than non-HCC patients. These result provide a reference for understanding the relationship between viral mutation and the progression of HBV infection-related diseases.

Objective This study was to develop a"Spleen Deficiency Certificate Scale for County Residents"and test its reliability.It was then developed as an objective tool for Chinese medicine evidence and symptoms for the prevention and control of chronic diseases among county residents.Methods The scale was compiled based on the team's previous foundation.The reliability of the scale was evaluated using internal consistency reliability and split-half reliability,while its validity was evaluated using structural validity,content validity,calibration validity,and discriminant validity.Results The study included 213 adults from Lanxi,of whom 155 were tested for intestinal flora.Seven scale entries were identified:Fatigue,fear of cold,bland mouth,loss of appetite,diarrhea,weak bowel movements,and tooth-marked tongue.In the reliability test,Cronbach's alpha coefficient was 0.828 and McDonald's ω coefficient was 0.825.The"stomach pain"and"bloating"entries did not meet the inclusion requirements and were recommended to be deleted.The Spearman-Brown coefficient was 0.839.The exploratory factor analysis of the two common factors explained 61.6%of the cumulative variance.The calibration validity indicated that the ratio of salivary amylase activity before and after acid stimulation was 0.826±0.253 in the group with spleen deficiency.Significant differences(P<0.05)in the genera Dialister,Shigella,Leuconostoc,Photobacterium,Trabulsiella,and Parvimonas between the spleen deficiency group and the non-spleen deficiency group.Conclusion The Spleen Deficiency Scale for County Residents demonstrates good reliability and validity.

ObjectiveTo observe the effect of Qinggan Jianpi Huoxue prescription（QGJPHXP） on the polarization of M1/M2 macrophages in rats with hepatic fibrosis induced by carbon tetrachloride（CCl₄）. MethodA rat hepatic fibrosis model was established by intraperitoneal injection of 40% CCl₄-olive oil suspension twice a week at the dosage of 2.0 mL·kg^-1 for 8 weeks. After the model was successfully established， these rats were randomly divided into the model group， QGJPHXP group（32.084 g·kg^-1） and Biejiajian pills（BJJP） group（0.925 5 g·kg^-1）， with 12 rats in each group. The blank group was injected intraperitoneally with the same amount of olive oil. The rats in the administration groups were given the corresponding solution according to the dose， and the blank and model groups were given the same dose of purified water， once a day. After 4 weeks of continuous administration， the liver tissues of rats were taken and stained with hematoxylin-eosin（HE） and Masson to observe the pathological changes. The serums were collected to detect the alanine aminotransferase（ALT） and aspartate aminotransferase（AST） levels. Interleukin（IL）-6， IL-12， IL-10， IL-1β， transforming growth factor-β₁（TGF-β₁） and tumor necrosis factor-α（TNF-α） levels in liver tissues were measured by enzyme-linked immunosorbent assay（ELISA）. The expression levels of CD86 and CD206 were detected by immunohistochemistry（IHC）. Western blot and real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） were used to detect the protein and mRNA expression levels of inducible nitric oxide synthase（iNOS）， arginase-1（Arg-1）， phosphorylated p38 mitogen-activated protein kinase（p-p38 MAPK）， nuclear transcription factor-κB p65（NF-κB p65） in liver tissues of rats. ResultCompared with the blank group， the hepatic cell plate was irregularly arranged, and local inflammatory cell infiltration and fibrous hyperplasia were observed， while the serum levels of ALT and AST were significantly increased in the model group（P<0.01）， and IL-1β， IL-6， IL-12， TGF-β₁， TNF-α， CD86， CD206， iNOS， p-p38 MAPK，p38 MAPK and NF-κB p65 levels in liver tissues were obviously increased（P<0.05， P<0.01）， while the levels of IL-10 and Arg-1 were obviously decreased（P<0.05， P<0.01）. Compared with the model group， QGJPHXP group reduced the degree of liver cell fibrosis，and serum levels of ALT and AST（P<0.01）， and IL-1β， IL-6， IL-12， TGF-β₁， TNF-α， CD86， iNOS， p-p38 MAPK， p38 MAPK， and NF-κB p65 levels in liver tissues were obviously decreased（P<0.05， P<0.01）， the levels of IL-10， CD206 and Arg-1 were obviously increased in the QGJPHXP group（P<0.05， P<0.01）. ConclusionQGJPHXP has ability to inhibit the activation of pro-inflammatory M1 macrophages， induce the secretion of anti-inflammatory cytokines by M2 macrophages， reduce the release of pro-fibrogenic cytokines， and promote the macrophage polarization of M1 to M2 in liver for tissue repair， thereby serving as an anti-inflammatory and anti-hepatic fibrosis drug.

Objective     To analyze predictive factors, clinical implications and prognosis effects of new-onset conduction block after transcatheter aortic valve implantation (TAVI). Methods     The clinical data of 86 patients who underwent TAVI through transfemoral approach from 2019 to 2021 in Fujian Provincial Hospital were retrospectively analyzed, including 59 males and 27 females with an average age of 72.9±8.0 years. The patients were divided into a normal group and a new-onset conduction block group according to whether there was new-onset conduction block after operation, and then the new-onset conduction block group was subdivided into a left bundle branch block (LBBB) group (28 patients) and a complete atrioventricular block (CAVB) group (11 patients). We compared the hemodynamics and TAVI-related complications between the postoperative and early follow-up periods, and used the multivariate logistic regression models to identify risk factors for the new-onset conduction block. Results     The median EuroSCORE of all patients were 8 (2) points before the operation. In the postoperative and early follow-up periods, the hemodynamics and TAVI-related complications had no statistical difference between the new-onset conduction block group and the normal group (P>0.05). The incidence of permanent pacemaker implantation (81.8%, 9/11) and mortality due to cardiac causes (18.1%, 2/11) in the CAVB group were significantly higher than those in the normal group and theLBBB group (P<0.05). Female, severe calcification of the aortic valve, too large valve size and deep valve implants were the risk factors for new-onset conduction block after TAVI. Conclusion    The incidence of LBBB and CAVB is high after TAVI, however, both of them do not significantly effect the hemodynamics of the patients. Higher incidence of permanent pacemaker implantation is found in the CAVB group which affects the rate of rehospitalization and mortality. Female patients, severe calcification of the aortic valve, too large valve size and deep valve implants are the risk factors for the new-onset conduction block after TAVI.

Objective     To investigate the effect of ginkgolide B (GB) on cysteinyl aspartate specific proteinase-3 (Caspase-3)/chromosome 10 deletion phosphatase-tension protein homologue (PTEN)/protein kinase B (Akt) pathway and cell proliferation and apoptosis in hypoxia/reoxygenation cardiomyocytes. Methods     H9C2 cells were cultured in vitro. A control group was cultured in serum-free DMEM high glucose medium at 37°C and 5% CO2 for 28 hours. The remaining groups were prepared with hypoxia/reoxygenation models. A GB low-dose group and a GB high-dose group were treated with GB pretreatment with final concentration of 50 μmol/L and 200 μmol/L respectively at 1 h before hypoxia/reoxygenation. A carvedilol group was treated with carvedilol of a final concentration of 10 μmol/L at 1 h before hypoxia/reoxygenation. The proliferation and apoptosis of H9C2 cells were detected, and the levels of lactate dehydrogenase (LDH), malondialdehyde (MDA), reactive oxygen species (ROS), PTEN, Akt, phosphorylated Akt (p-Akt) and Caspase-3 in H9C2 cells were also detected. Results     Compared with the control group, the proliferation rate of H9C2 cell, and the levels of PTEN, Akt and p-Akt in other groups decreased, and the apoptosis rate, and the levels of LDH, MDA, ROS and Caspase-3 increased (P<0.05). Compared with the hypoxia/reoxygenation group, the proliferation rate of H9C2 cell, and the levels of PTEN, Akt and p-Akt in all GB dose groups and the carvedilol group increased; the apoptosis rate, and the levels of LDH, MDA, ROS and Caspase-3 decreased, and the effect of GB was in a dose dependent manner; however, the effect of GB was not as strong as carvedilol (P<0.05). Conclusion     GB can inhibit H9C2 cell apoptosis and promote H9C2 cell proliferation by activating Caspase-3/PTEN/Akt pathway.

Objectives:To understand the awareness rate and its influencing factors of their HBV infection status among HBsAg-positive persons aged 15-69 years in China.Methods:A cross-sectional design was used to conduct a questionnaire survey on the awareness of their infection status among HBsAg-positive persons aged 15-69 years who were identified in the 2020 national hepatitis B seroepidemiology survey. The awareness rate of the whole respondent and respondents with different characteristics were described, and the differences were compared with the χ2 test. The logistic regression model was used to analyze the factors influencing the awareness rate. Results:The overall awareness rate among the respondents was 43.10% (1 828/4 241). The awareness rate was lower in males than in females (41.30% vs. 44.65%). The awareness rate was lower in the 60-69-years-old age group than in other age groups (30.38% vs. 36.77%-57.58%). The awareness rate was lower in rural areas than in urban areas (39.43% vs. 47.32%). The awareness rate was lower in regions with a per capita gross domestic product (GDP) below RMB 54 000 than in regions with a per capita GDP of RMB 54 000 and above (36.81% vs. 41.61%-50.30%). The awareness rate was lower in respondents without other liver diseases than with other liver diseases (41.52% vs. 60.68%). The awareness rate was lower in respondents without a family history of hepatitis B-related disease or unknown family history than with a family history (43.58% vs. 68.26%; 24.71% vs. 68.26%). Multivariate logistic regression analysis showed that male [odds ratio ( OR)=0.841, 95% confidence interval ( CI): 0.734-0.964], high school and below [primary school and below, junior middle school, high school/technical secondary school, OR (95% CI): 0.247 (0.190-0.321), 0.451 (0.352-0.577), 0.634 (0.486-0.827)], rural areas ( OR=0.822, 95% CI: 0.715-0.945) and regions with a per capita GDP below RMB 80 000 [54 000-80 000, OR (95% CI): 0.810 (0.688-0.954), below RMB 54 000, OR (95% CI): 0.793 (0.669-0.941)] were the negative factors influencing the awareness rate. While 30-39-years-old ( OR=2.089, 95% CI: 1.626-2.683) and 40-49-years-old ( OR=1.590, 95% CI: 1.250-2.023) age groups, with other liver diseases ( OR=2.244, 95% CI: 1.754-2.871) and family history related to hepatitis B ( OR=2.688, 95% CI: 2.242-3.223) were the positive factors influencing the awareness rate. Conclusion:The overall awareness rate of their infection status among HBsAg-positive persons aged 15-69 years is 43.10% in China. Health promotion and coverage expansion on HBV screening should be further strengthened to achieve the proposed World Health Organization's target of 90% HBV infection diagnosis rate by 2030.

Viral hepatitis has been causing big threat to public health globally. The number of annual deaths caused by hepatitis surpassed the deaths caused by AIDS, tuberculosis, and malaria. World Health Organization (WHO) issued the global health sector strategy on viral hepatitis 2016-2020 (GHSS) to control its epidemic. It established the Strategies and Technical Advisory Committee on HIV, viral hepatitis, and sexually transmitted infections (STAC). This paper summarizes the GHSS goals and the keynote of the 2020 STAC meeting, analyzes the challenges and opportunities faced by China in eliminating viral hepatitis, and provides the comments on the papers on this issue, which could guide further actions.

Objective:To understand the epidemiological characteristics of hepatitis B in China, evaluate the performance of elimination hepatitis B in China and provide scientific evidence for the prevention and control of hepatitis B.Methods:An analysis was conducted by using the data of hepatitis B cases reported to the National Notifiable Disease Reporting System (NNDRS) from the areas with low, moderate and high hepatitis B prevalence in China from 2013 to 2020, and the information about the diagnoses of the hepatitis B cases were collected, the incidence of hepatitis B was estimated according to the reporting and diagnosis information and the characteristics of acute and chronic hepatitis B were compared.Results:A total of 27 013 hepatitis B cases were reported to NNDRS, including 4 070 acute cases, 21 971 chronic cases and 972 unclassified cases. Among the reported acute hepatitis B cases, 69.9% (2 845/4 070) were confirmed. Among the reported chronic hepatitis B cases, 89.0% (19 548/21 971) were confirmed, and 2.1% (452/21 971) were confirmed as acute cases. It was estimated that the incidence of acute hepatitis B was 4.6/100 000 and the incidence of chronic hepatitis B cases was 54.5/100 000. The case number of acute hepatitis B in age group 31-45 years was highest, accounting for 35.3% (1 164/3 297). The case number of acute hepatitis B in children under 15 years old was lowest, accounting for 0.4% (13/3 297). The case number of chronic hepatitis B in age group 46-60 years was highest, accounting for 34.4% (7 211/20 932).Conclusions:The incidence of acute hepatitis B was in decrease and the incidence of chronic of hepatitis B was in increase in China year by year. It is important to strengthen the standardized diagnosis and treatment of chronic hepatitis B to decrease the morbidity and mortality of hepatitis B. At the same time, it is necessary to standardize the management and reporting of hepatitis B cases reported to NNDRS to improve the accuracy of the reporting of hepatitis B.

Objective:To understand the characteristics of hepatitis B cases reported through the National Notifiable Disease Reported System (NNDRS) of China in 2019, analyze the quality of hepatitis B reporting.Methods:The survey forms and reporting cards of hepatitis B cases in 200 surveillance points in China in 2019 were collected from NNDRS, the completeness rate of the reporting card was calculated, and the reported hepatitis B cases were verified based on the diagnostic criteria (WS 299-2008). The clinical types of the cases after verification were compared with the reported ones, the consistency was evaluated with Kappa test. The reasons for the inconsistent clinical types of the cases were analyzed.Results:In 2019, a total of 64 686 hepatitis B cases were reported through NNDRS. Acute, chronic and unclassified hepatitis B cases accounted for 5.8%, 92.4% and 1.8%, respectively. The average age of reported cases was 47 (47±15) years, and males accounted for 64.4%. The average level of alanine aminotransferase was 214.2 (214.2±1 253.4) U/L. The reported cases mainly worked in agriculture, forestry, animal husbandry, fishery, and water conservancy (50.6%, 32 722). The proportions of cases reported from the eastern, western and central regions were 42.5% (27 501),22.1% (14 315) and 35.4% (22 870), respectively. The consistent rate of the clinical types between the reported cases and the verified cases was 58.8%, with a Kappa value of 0.15. For the 39 271 cases confirmed as acute and chronic hepatitis B cases in the reporting cards, the consistent rate of the clinical types between the reported cases and the verified cases was 96.9%, with a Kappa value of 0.73. In 94.5% (24 267/25 681) of the cases with inconsistent clinical types, the reporting card information were incomplete.Conclusion:The diagnosis of hepatitis B has been improved in the hepatitis B surveillance in China, but it is necessary to improve the completeness of the reporting cards of hepatitis B cases to NNDRS.
