ABSTRACT
Objective:To compare the efficacy of the combination of abidol, lopinavir/ritonavir plus recombinant interferon α-2b (rIFNα-2b) and the combination of lopinavir/ritonavir plus rIFNα-2b for patients with COVID-19 in Zhejiang province.Methods:A multicenter prospective study was carried out to compare the efficacy of triple combination antiviral therapy and dual combination antiviral therapy in 15 medical institutions of Zhejiang province during January 22 to February 16, 2020. All patients were treated with rIFNα-2b (5 million U, 2 times/d) aerosol inhalation, in addition 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir/ritonavir (2 tablets, 1 time/12 h) (triple combination group) and 41 patients were treated with lopinavir/ritonavir (2 tablets, 1 time/12 h) (dual combination group). The patients who received triple combination antiviral therapy were further divided into three subgroups: <48 h, 3-5 d and >5 d according the time from the symptom onset to medication starting. The therapeutic efficacy was compared between triple combination group and dual combination group, and compared among 3 subgroups of patients receiving triple combination antiviral therapy. SPSS 17.0 software was used to analyze the data.Results:The virus nucleic acid-negative conversion time in respiratory tract specimens was (12.2±4.7) d in the triple combination group, which was shorter than that in the dual combination group [(15.0±5.0) d] ( t=6.159, P<0.01). The length of hospital stay in the triple combination group [12.0 (9.0, 17.0) d] was also shorter than that in the dual combination group [15.0 (10.0, 18.0) d] ( H=2.073, P<0.05). Compared with the antiviral treatment which was started within after the symptom onset of in the triple combination group, the time from the symptom onset to the viral negative conversion was 13.0 (10.0, 17.0), 17.0 (13.0, 22.0) and 21.0 (18.0, 24.0) d in subgroups of 48 h, 3-5 d and >5 d, respectively ( Z=32.983, P<0.01), while the time from antiviral therapy to viral negative conversion was (11.8±3.9), (13.5±5.1) and (11.2±4.3) d, respectively( Z=6.722, P<0.05). Conclusions:The triple combination antiviral therapy of abidol, lopinavir/litonavir and rIFNα-2b shows shorter viral shedding time and shorter hospitalization time, compared with the dual combination antiviral therapy; and the earlier starting triple combination antiviral therapy will result in better antiviral efficacy.

ABSTRACT
Objective@#To analyze the prevalence of severe fever with thrombocytopenia syndrome virus(SFTSV)infection in Zhoushan island of Zhejiang province and the duration of serum positive IgG antibody in patients infected with SFTSV.@*Methods@#One thousand one hundred and twenty-two healthy people from Zhoushan island of Zhejiang province were recruited for cross-sectional study in August 2019, including 641 from non-epidemic areas and 481 from epidemic areas. The serum SFTSV-IgG antibody was detected by enzyme-linked immunosorbent assay (ELISA), and the positive rates of SFTSV-IgG antibody were compared between people from the epidemic areas and non epidemic areas. Meanwhile, the antibody titer of SFTSV-IgG in 19 patients confirmed between July 2011 and June 2018 was detected by indirect ELISA. SPSS 17.0 software was used to analyze data.@*Results@#The positive rate of SFTSV-IgG antibody was 1.5% (7/481) in the epidemic area, which was higher than that in the non-epidemic area (0/641) (χ2=7.187, P<0.01). The positive rates of SFTSV-IgG antibody in 2019 were lower than those in the epidemic area (11.7%) and non-epidemic area (2.5%) in 2013 (χ2=22.556 and 10.352, both P<0.01). The serum SFTSV-IgG antibody of 18 patients with previous infection was still positive, and the longest one lasted for 8 years.@*Conclusions@#There is a SFTSV latent infection in population from epidemic area of Zhoushan island. The SFTSV-IgG antibody can last for a long time in patients with SFTS and it may have certain protective effect.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of controlled attenuation parameter (CAP) in the diagnosis of fatty liver using FibroScan in patients with chronic liver disease (CLD).</p><p><b>METHODS</b>A prospective cohort study was performed for the patients with chronic hepatitis B (CHB), chronic hepatitis C (CHC), and non-alcoholic fatty liver disease (NAFLD) who underwent liver pathological examination followed by CAP measurement within 1 week in The Second People's Hospital of Tianjin from February 2013 to May 2014. According to related guidelines, hepatocyte steatosis was classified as S0: <5%, S1: 5%-33%, S2: 34%-66%, or S3: ≥67%. The receiver operating characteristic (ROC) curves were plotted with positive results as the diagnostic criteria, and the optimal cut-off values were determined at the maximum Youden index. Single linear regression and multiple stepwise regression were applied to analyze the influencing factors for CAP.</p><p><b>RESULTS</b>A total of 427 patients were enrolled, consisting of 19 patients (4.4%) with NAFLD, 383 (89.7%) with CHB, and 25 (5.9%) with CHC. The optimal cut-off values for CAP in the diagnosis of steatosis ≥5%, ≥34%, and ≥67% were 230 dB/m, 252 dB/m, and 283 dB/m, respectively, and the areas under the ROC curve were 0.803, 0.942, and 0.938, respectively (Z = 14.194, 28.385, and 16.486, respectively, all P < 0.01). CAP differentiated S0 from S1, S1 from S2, S0 from S2, S0 from S3, and S1 from S3 (Z = 10.109, 10.224, 47.81, 29.917, and 10.999, all P < 0.01), but was not able to differentiate S2 from S3 (Z = 0.656, P = 0.5116). The single linear regression and multiple stepwise regression analyses showed that only body mass index (BMI; B = 4.001, P < 0.01) and hepatic steatosis (B = 33.015, P = 0.000) were correlated with CAP. The coincidence rates between CAP and liver pathological diagnosis were 77.4%, 81.0%, and 96.2% for S0, S3, and ≥S2, respectively.</p><p><b>CONCLUSION</b>CAP has a good value in the diagnosis of fatty liver in CLD patients, and can well differentiate between all stages of fatty liver except S2 and S3. CAP is influenced by BMI, but is not found to be associated with liver fibrosis, inflammation, liver stiffness measurement, and etiology.</p>

ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of the cytoplasmic DNA sensor DAI on replication of hepatitis B virus (HBV) and its possible mechanism.</p><p><b>METHODS</b>The hepatocyte-derived cell line HepG2 was co-transfected with DAI siRNA and the HBV1.3 replicative plasmid PHY106, and the cells were divided into two experimental groups. Six hours later, total RNA was extracted from the first group of cells and expression of IFIT1 and IL-6 were detected by real-time RT-PCR. The second group of cells was incubated for 4 days, after which the cell supernatant was collected and the HBV surface antigen (HBsAg) and envelope antigen (HBeAg) were detected by ELISA. In addition, HBV core particles were extracted and applied to southern blot assay to detect the intracellular HBV replication intermediates (rcDNA, dlDNA and ssDNA). Next, the HepG2 cells were triple transfected with siRNA targeting the type I interferon pathway molecule TBK1 and DAI simultaneously and HBV1.3, after which HBV viral proteins were detected. Two-group comparisons were made using the independent sample t-test, and more-than-2-group comparisons were made using ANOVA.</p><p><b>RESULTS</b>DAI gene expression was down-regulated in response to DAI siRNA transfection. Cells with down-regulated DAI showed inhibited HBV replication (in a dose-dependent manner), accompanied by reduced levels of HBsAg (0.0195+/-0.0050 vs.</p><p><b>CONTROL</b>0.3150+/-0.0200, P less than 0.05, t = 14.77) and HBeAg (0.0140+/-0.0040 vs.</p><p><b>CONTROL</b>0.01235+/-0.0135, P less than 0.05, t = 7.777). No effect of down-regulated DAI was observed for the expression of IFIT1 of IL-6. siRNA-mediated down-regulation of TBK1 and DAI simultaneously led to reduced expression of HBsAg and HBeAg.</p><p><b>CONCLUSION</b>Down-regulation of DAI gene expression inhibited HBV replication and HBV protein expression, but the underlying mechanism was not related to the type I interferon or NF-kB signaling pathway.</p>

ABSTRACT
Objective:To evaluate the importance of 3D-CTA with volume rendering for the diagnosis of multiple intracranial aneurysms. Methods: Axial source images were obtained by helical CT scanning and reconstruction of 3D-CTA images was done by volume rendering technique in conjunction with multiplanar reformation. Results: In the past one year,there were 10 patients diagnosed as having multiple intracranial aneurysms by 3D-CTA and altogether 24 aneurysms were visualized,including 10 small aneurysms(≤5mm.Three dimensional CT angiography with volume rendering demonstrated aneurysms very well and provided useful information concerning the site,shape,size and spatial relationship with the surrounding vessels and bone anatomy. Conclusion: Three-dimensional CT angiography with volume rendering is a quick,reliable,and relatively noninvasive method for diagnosing multiple intracranial aneurysms.It delineates detailed aneurysmal morphology,and provides useful information for planning microsurgical approaches.
ABSTRACT
The authors described two cases with primitive trigeminal artery. Case 1 was a 32-year-old woman who suffered dizziness and a serious pulsatile intracranial bruit on the left ear, and sometimes associated with pulsatile intracranial bearing-pain on the left temporal side six months before she was admitted to the hospital. She also suffered from obvious diplopia on left lateral gaze for the last 5 months. She had suffered no recent trauma. Magnetic resonance imaging(MRI) demonstrated a suspected intracranial aneurysm located in left cavernous sinus. Digital subtraction angiography (DSA) was performed and a primitive trigeminal artery-cavernous sinus fistula in left side was found. Intraluminal occlusion of the fistula was successfully performed immediately after angiography using 6 Guglielmi detachable coils (GDC), and the patient was cured finally. Case 2 was a 28-year-old woman who suffered a serious intermittent cephalodynia associated with soreness on the left body two years before she was admitted to the hospital. She had suffered no recent trauma. Magnetic resonance angiography(MRA) demonstrated a suspected intracavernous aneurysm of the right internal carotid artery, Digital subtraction angiography (DSA) was performed. Right internal carotid angiography showed a primitive trigeminal artery (PTA) run between the cavernous segment of the internal carotid artery and the distal portion of the basilar artery. On initiation of PTA of R-ICA a small wide-necked saccular aneurysm was incidentally visualized. The aneurysm was successfully embolized after angiography using 2 Stent (Neuroform, 4.5mmm × 20mmm)-assisted detachable coils (Matrix), the ICA and PTA were preserved, and the patient was cured finally.

<p><b>OBJECTIVES</b>To analyse the characteristics of interventional treatment for anterior communicating artery aneurysm (AcoAA) and improve curative effects.</p><p><b>METHODS</b>In 126 patients, detachable microcoils were used to embolize the AcoAA via endovascular approach. Those patients failed to be embolized were treated by surgical clipping.</p><p><b>RESULTS</b>Of the 109 patients who were embolized successfully, 97 were achieved 100% occlusion, 12 95% - 98% occlusion. In the other 17 patients who failed to interventional treatment 15 were treated surgically and 2 no treatment because of cerebral vascular spasm. 123 patients were cured, one died, and 2 had aneurysms disappeared without any operations, as proved by follow-up for 5 months to 1 years. Of 32 patients checked by cerebral angiography 3 weeks to 30 months after operation, 30 showed disappeared of aneurysms and 2 had recurrence. The recurred aneurysms were successfully reembolized.</p><p><b>CONCLUSIONS</b>Most of AcoAAs can be cured by endovascular interventional treatment. Those who failed to be treated by embolization can be cured surgically. Few patients may be healed spontaneously. The long term effects of treatment should be followed-up for a long time.</p>
