ObjectiveTo evaluate the methodological quality and reporting quality of published guidelines/consensuses on traditional Chinese medicine （TCM）/integrated traditional Chinese and Western medicine diagnosis and treatment of nonalcoholic fatty liver disease （NAFLD）， and to provide a basis for formulating guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD in the future. MethodsDatabases including PubMed， Embase， Web of Science， CNKI， Wanfang Data， and CBM and the websites of China Association of Chinese Medicine and China Association of Integrative Medicine were searched for related articles published up to September 1， 2024. Two clinical researchers independently assessed the methodological quality and reporting quality of the guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD by using Appraisal of Guidelines for Research and Evaluation Ⅱ （AGREE Ⅱ） and Reporting Items for Practice Guidelines in Healthcare （RIGHT）. ResultsA total of nine guidelines/consensuses were included after literature screening， with four guidelines and five expert consensuses. The scores of different domains assessed by AGREE Ⅱ for the nine guidelines/consensuses were as follows： scope and purpose （47.1%）， stakeholder involvement （41.0%）， rigor of development （21.6%）， clarity of presentation （40.2%）， applicability （19.0%）， and editorial independence （19.6%）. The recommendation level of the articles was B level （recommended after revision） for four articles and C level （not recommended） for five articles. The RIGHT assessment showed high reporting rates for “Basic Information” and “Background”， while other areas needed to be improved. Currently， there was no international standard for the guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD， and the quality of these guidelines/consensuses needed to be enhanced to ensure comprehensiveness and credibility. ConclusionThere is still potential for improving the quality of guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD， and AGREE Ⅱ and RIGHT checklists should be strictly followed to ensure the fairness， scientific rigor， and transparency of these guidelines/consensuses.

Objective:To investigate ability of HCA587/MAGE-C2 protein combined with different adjuvants inducing antigen-specific immune response and antitumor effects in mice model.Methods:C57BL/6J mice were immunized with HCA587 protein com-bined with Freund's complete adjuvant(CFA)/Freund's incomplete adjuvant(IFA)and different doses of CpG ODN 1826(CpG),cellular and humoral immunity levels induced by different schemes were compared.ELISpot was used to evaluate frequency of IFN-γ-producing splenocytes.HCA587-specific antibodies were detected by ELISA.Intracellular cytokine staining(ICCS)analysis was mea-sured by flow cytometry.A tumor-bearing animal model was created by subcutaneously injection of B16-HCA587 tumor cells into right flank of C57BL/6J mice,which was treated with strategy with the strongest cellular and humoral immune response in immune compari-son protocol.Vernier calipers were used to measure tumor volume,and Log-rank test was used to analyze survival curve.Results:HCA587 protein combined with CFA and 50 μg CpG elicited strongest specific IFN-γ-secreting splenocytes and anti-HCA587 anti-bodies,which induced highest IFN-γ+CD4+T cells(P<0.05).In tumor treatment model,HCA587 protein combined with CFA and 50 μg CpG significantly inhibited tumor growth(P=0.026),while Log-rank test showed no significant effect on survival(P>0.05).Conclusion:HCA587 protein vaccine formulated with CFA and 50 μg CpG causes a significant cellular and humoral immune response and partial antitumor effect in mice model,providing new experimental data for preclinical research of tumor antigen protein vaccine.

ObjectiveTo investigate the cognition of e-cigarette compositions and hazards and its influencing factors among secondary school personnel （junior， senior and vocational high school） in Shanghai， so as to provide ideas for improving the cognition level of e-cigarettes among the school personnel and tobacco control efforts on campus in the future. MethodsA multi-stage stratified cluster random sampling method was used to conduct an anonymous online questionnaire survey among 1 767 secondary school personnel in Shanghai. ResultsThe proportion of school staff who had used e-cigarettes was 3.79%. The participants who were not sure whether the e-cigarette smoke was “mainly water vapor （incorrect）” and whether the e-cigarette smoke “contained nicotine （correct）” and “contained formaldehyde （correct）” accounted for 62.71%， 54.44% and 61.91%， respectively. Among them， 68.48%， 55.46% and 50.37%， respectively， agreed that e-cigarettes would be “addictive”， “harmful” and “that second-hand smoke was harmful”. Binary logistic regression analysis showed the following risk factors for the low level of school personnel’s awareness of e-cigarette compositions： age ≥40 years （OR=1.65， 95%CI： 1.32‒2.06）， working in junior high school （OR=1.37， 95%CI： 1.09‒1.73）， educational attainment level as junior college or below （OR=1.67， 95%CI： 1.02‒2.74）， and not having participated in tobacco control education activities （OR=1.37， 95%CI： 1.08‒1.73）. Meanwhile， working in junior （OR=1.43， 95%CI： 1.12‒1.83） or senior （OR=1.44， 95%CI： 1.08‒1.92） high school， educational attainment level as junior college or below（OR=2.10， 95%CI： 1.24‒3.56）， having used e-cigarettes （OR=2.98， 95%CI： 1.63‒5.42）， not having participated in tobacco control education activities （OR=1.49， 95%CI： 1.16‒1.92） and low level of awareness of e-cigarette compositions （OR=4.24， 95%CI： 3.44‒5.23） were risk factors for the low level of school personnel’s awareness of e-cigarette hazards. ConclusionsThe level of e-cigarette awareness among school personnel in Shanghai is low， especially those who are older， had low educational attainment level and had used e-cigarettes. In the future， tobacco control education for school personnel should be strengthened to improve their cognition and ability of tobacco control on campus.

In recent years, with the vigorous marketing of e-cigarette manufacturers, e-cigarettes have become a popular tobacco product for adolescents. The problem of e-cigarette environmental exposure among adolescents is also getting worse and its associated adverse impacts cannot be ignored. However, domestic research on the environmental exposure to e-cigarettes among youth is insufficient, and experience on e-cigarette regulation is also limited. This review first briefly introduced the definition and sources of e-cigarette environment exposure, then focused on the differences of e-cigarette environmental exposure among adolescents with different characteristics to identify possible influencing factors, as well as the impacts of e-cigarette environmental exposure on adolescents, and finally summarized international countermeasures to prevent e-cigarette environmental exposure in adolescents, aiming to provide directional guidance for China to conduct e-cigarette control activities among adolescents.

Objective To explore the value of ¹⁸F-FDG PET/CT in the diagnosis of cholangiocarcinoma. Methods Data were collected from 44 patients with cholangiocarcinoma who underwent PET/CT in Affiliated Cancer Hospital of Shandong First Medical University from September 2017 to October 2020. All patients underwent upper abdominal CT and MRI and whole-body PET/CT. The diagnostic value of three examinations was compared for primary lesions, recurrent lesions, and regional lymph node metastasis of cholangiocarcinoma. Results There were no significant differences in the diagnostic sensitivity of CT, MRI, and PET/CT in the primary lesions and regional lymph node metastasis of cholangiocarcinoma (P > 0.05). There were significant differences in the diagnostic sensitivity of the three examinations for recurrent cholangiocarcinoma lesions (P < 0.05). Conclusion PET/CT has high diagnostic value for recurrent lesions of cholangiocarcinoma, but the three examinations showed no significant differences in the diagnostic sensitivity for primary lesions and regional lymph node metastasis.

Background::To date, there is no effective medicine to treat coronavirus disease 2019 (COVID-19), and the antiviral efficacy of arbidol in the treatment for COVID-19 remained equivocal and controversial. The purpose of this study was to evaluate the efficacy and safety of arbidol tablets in the treatment of COVID-19.Methods::This was a prospective, open-label, controlled and multicenter investigator-initiated trial involving adult patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients were stratified 1:2 to either standard-of-care (SOC) or SOC plus arbidol tablets (oral administration of 200 mg per time, three times a day for 14 days). The primary endpoint was negative conversion of SARS-CoV-2 within the first week. The rates and 95% confidential intervals were calculated for each variable.Results::A total of 99 patients with laboratory-confirmed SARS-CoV-2 infection were enrolled; 66 were assigned to the SOC plus arbidol tablets group, and 33 to the SOC group. The negative conversion rate of SARS-CoV-2 within the first week in patients receiving arbidol tablets was significantly higher than that of the SOC group (70.3% [45/64] vs. 42.4% [14/33]; difference of conversion rate 27.9%; 95% confidence interval [CI], 7.7%-48.1%; P = 0.008). Compared to those in the SOC group, patients receiving arbidol tablets had a shorter duration of clinical recovery (median 7.0 days vs. 12.0 days; hazard ratio [HR]: 1.877, 95% CI: 1.151-3.060, P = 0.006), symptom of fever (median 3.0 days vs. 12.0 days; HR: 18.990, 95% CI: 5.350-67.410, P < 0.001), as well as hospitalization (median 12.5 days vs. 20.0 days; P < 0.001). Moreover, the addition of arbidol tablets to SOC led to more rapid normalization of declined blood lymphocytes (median 10.0 days vs. 14.5 days; P > 0.05). The most common adverse event in the arbidol tablets group was the elevation of transaminase (5/200, 2.5%), and no one withdrew from the study due to adverse events or disease progression. Conclusions::SOC plus arbidol tablets significantly increase the negative conversion rate of SARS-CoV-2 within the first week and accelerate the recovery of COVID-19 patients. During the treatment with arbidol tablets, we find no significant serious adverse events.Trial registration::Chinese Clinical Trial Registry, NCT04260594, www.clinicaltrials.gov/ct2/show/NCT04260594?term= NCT04260594&draw=2&rank=1

Background and Objectives: Psoriasis is a chronic inflammatory skin disease, which the mechanisms behind its initiation and development are related to many factors. DMSCs (dermal mesenchymal stem cells) represent an important member of the skin microenvironment and play an important role in the surrounding environment and in neighbouring cells, but they are also affected by the microenvironment. We studied the glucose metabolism of DMSCs in psoriasis patients and a control group to reveal the relationship among glucose metabolism, cell proliferation activity，and VEC (vascular endothelial cell) differentiation in vitro, we demonstrated the biological activity and molecular mechanisms of DMSCs in psoriasis. Methods: and Results: We found that the OCR of DMSCs in psoriatic lesions was higher than that in the control group, and mRNA of GLUT1 and HK2 were up-regulated compared with the control group. The proliferative activity of DMSCs in psoriasis was reduced at an early stage, and mRNA involved in proliferation, JUNB and FOS were expressed at lower levels than those in the control group. The number of blood vessels in psoriatic lesions was significantly higher than that in the control group (p＜0.05), which the mRNA of VEC differentiation, CXCL12, CXCR7, HEYL and RGS5 tended to be increased in psoriatic lesions compared to the control group, in addition to Notch3. Conclusions We speculated that DMSCs affected local psoriatic blood vessels through glucose metabolism, and the differentiation of VECs, which resulted in the pathophysiological process of psoriasis.

OBJECTIVE: To determine the carrier rate of Fragile X mental retardation 1 gene (FMR1) mutants in women with a history of adverse pregnancy or childbirth, and to provide prenatal diagnosis for the carriers. METHODS: Peripheral blood samples were collected from women with a history of adverse pregnancy or childbirth, and the FMR1 gene cytosine-guanine-guanine repeat number (CGG)n was determined by triple-repeat primer polymerase chain reaction (TP-PCR) combined with capillary electrophoresis. Prenatal diagnosis was provided for the carriers during pregnancy. RESULTS: Among 819 samples, 9 gray zone repeats carriers and 10 premutation carriers were detected, which gave a prevalence of 1 in 91 and 1 in 82, respectively, with a total prevalence of 1 in 43. Prenatal diagnosis was provided during 7 pregnancies for 6 carriers. A female fetus with premutation (n = 30/57) and an affected male fetus with full mutation (n = 336) were detected. CONCLUSION FMR1 gene testing in women with a history of adverse pregnancy or childbirth can facilitate genetic counseling and reproductive guidance for carriers of gray zone repeats and premutations. Prenatal diagnosis for carriers of premutation can facilitate reduction of the birth of children with fragile X syndrome.

Objective:To analyze the OCT angiography (OCTA) features of eyes affected with angioid streaks.Methods:Retrospective analysis of 26 patients (52 eyes) diagnosed as angioid streaks by multimodal imaging in Ophthalmology Department of Yunnan Second People’s Hospital from May 2017 to February 2019 were included in this study. There were 18 males and 8 females, with the mean age of 50.8±6.9 years. All the patients were binocular. There were 34 eyes in 20 patients with CNV. Among them, 13 eyes had a course of disease within 1 month, 16 eyes had a course of disease over 1 month, and 5 eyes were treated with anti-VEGF drugs. All patients were examined by ultra-wide-angle fundus photography, infrared fundus imaging (IR), spectral-domain OCT, FAF and FFA. At the same time, the Heidelberg OCTA instrument was used for OCTA examination. The central wavelength was 840 nm, the acquisition speed was 85,000 times/s, and the width was 45 nm. A 3 mm × 3 mm scan was obtained. Each cube consisted of two 304 B scans of repeated volumes, and motion correction was performed using two orthogonally captured image volume registration. The results of fundus color photography, IR, FAF, FFA, OCT and OCTA were compared and analyzed to summarize the image features of AS and its secondary CNV in OCTA.dus color photography, IR, FAF, FFA, OCT and OCTA were compared and analyzed to summarize the image features of AS and its secondary CNV in OCTA.Results:Among 52 eyes, 40 eyes showed choroidal capillary shadows in OCTA, and no obvious abnormal OCTA images in 12 eyes. Ten eyes OCTA showed a vascular network beseide the optic disc, FFA showed fluorescent staining instead of fluorescein leakage. Among the 52 eyes, 34 eyes had secondary macular CNV, and 34 eyes had different forms of CNV. Different forms had a certain correlation with the length of medical history and treatment history. Among them, 13 eyes with short course of disease (less than 1 month) and untreated patients had smaller flower-ring morphology, 16 eyes with longer course (more than 1 month) but no treatment had larger fan-shaped segments, and 5 eyes with anti-VEGF therapy were trimmed after the dendritic shape.Conclusions:AS streaks appeared no blood flow signal area in OCTA, and repairing vascular network beside the optic disc can be observed in some AS patients. The CNV performance with different disease course and treatment experience is different.
