Background:Kawasaki is acute fever disease with systematic vein infection which often seen in children under 5 years old. Objectives:Describe the clinical characteristics and laboratory, echocardiography data in children with Kawasaki between early diagnosed group and late one. Subjects and method: A descriptive, prospective study was carried out on 77 Kawasaki disease patients were selected, including 50 patients were diagnosed before day 10 of illness (group 1) and 27 patients were diagnosed on or after day 10 (group 2) in the National Pediatrics hospital from June 2004 to June 2006. Results:The mean was 13.4 months. Age under 12 months was 61 %. Male/female ratio was 1.7: 1. Fever, red lips, red eyes, skin rash, extremities edema and cervical lymphadenopathy occurred in the first week. The inflammatory response was strong (CRP: 83.6 mg/I, erythrocyte sedimentation rate (ESR) after an hour: 79.1 mm. WBC: 27800/ mm3). There were no differences between patients in the group 1 and group 2 in age, gender, time to the first medical visit, C-reactive protein (CRP) concentration, white blood cell count or erythrocyte sedimentation rate. Patients in the group 1 had significantly close clustering of symptoms onset in the first few days of illness, but patients in the group 2 had onset of symptoms scattered over 4 days. A platelet count of over 500.000/mm3 occurred more often in the group 2 (60%) than the group 1 (31.3%). Coronary involvement was observed in 23 patients (29.8%) including 17 patients who had coronary dilation and 6 patients with coronary aneurysm. Conclusion:Coronary artery abnormalities in the group 2 (48.1%) occurred significantly more than the group 1 (20%).

Background: Kawasaki is an acute fever disease with systematic vein infection and often seen in children.Objectives:This study aims to determine features and risk factors of coronary artery lesion (CAL) in Kawasaki disease in children. Subjects and method:A descriptive, prospective study was conducted on 83 patients diagnosed with Kawasaki disease whom treated at National Hospital for Pediatric from January 2005 to March 2007. They were divided into 2 groups: with and without CAL. All data from clinical characteristics, laboratory and echocardiography were analyzed to evaluate the differences between 2 groups. Univariate and multivariate analysis were used. Results: Among 83 patients diagnosed with Kawasaki disease, 27 patients (32.5%) was found with CAL. 24 patients (88.9%) had both right and left coronary artery abnormalities. The CAL in left anterior descending (LAD) and in left circumflex coronary artery (LCX) was 55.6% and 25.9% respectively. Risk level II: 7 patients (25.9%). Risk level III: 14 patients (51.9%) and risk level IV: 6 patients (22.2%). 14 patients (51.9%) with CAL were resolved at 6th month of the illness. Independent risk factors of CAL in acute stage included age under 12 months (OR = 3.97, p<0.05). IVIG treatment was within the first 10 day of the illness (OR=0.25, p<0.05). Non - responsiveness to \u03b3globulin therapy (OR=7.69, p<0.01). CRP before starting initial treatment above 90mg/1 (OR = 12.81, p<0.05). Platelets before starting \u03b3 globulin therapy ~ 557 000/ mm3 with OR=4.73 and p<0.05. Conclusion:Early detection and treatment were necessary in order to decrease CAL in patients with Kawasaki disease.

To investigated the protective potential of ethanol extracts of Scutellaria baicalensis (S. baicalensis ) against lipopolysaccharide (LPS)-induced liver injury. Methods: Dried roots of S. baicalensis were extracted with ethanol and concentrated to yield a dry residue. Mice were administered 200 mg/kg of the ethanol extracts orally once daily for one week. Animals were subsequently administered a single dose of LPS (5 mg/kg of body weight, intraperitoneal injection). Both protein and mRNA levels of cytokines, such as tumor necrosis factor alpha, interleukin-1β, and interleukin-6 in liver tissues were evaluated by ELISA assay and quantitative PCR. Cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB protein levels in liver tissues were analyzed by western blotting. Results: Liver injury induced by LPS significantly increased necrosis factor alpha, interleukin-1β, interleukin-6, cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB in liver tissues. Treatment with ethanol extracts of S. baicalensis prevented all of these observed changes associated with LPS-induced injury in liver mice. Conclusions: Our study showed that S. baicalensis is potentially protective against LPS-induced liver injury in mice.

Objectives:
Online misinformation has reached unprecedented levels during the coronavirus disease 2019 (COVID-19) pandemic. This study analyzed the magnitude and sentiment dynamics of misinformation and unverified information about public health interventions during a COVID-19 outbreak in Da Nang, Vietnam, between July and September 2020.
Methods:
We analyzed user-generated online information about five public health interventions during the Da Nang outbreak. We compared the volume, source, sentiment polarity, and engagements of online posts before, during, and after the outbreak using negative binomial and logistic regression, and assessed the content validity of the 500 most influential posts.
Results:
Most of the 54,528 online posts included were generated during the outbreak (n = 46,035; 84.42%) and by online newspapers (n = 32,034; 58.75%). Among the 500 most influential posts, 316 (63.20%) contained genuine information, 10 (2.00%) contained misinformation, 152 (30.40%) were non-factual opinions, and 22 (4.40%) contained unverifiable information. All misinformation posts were made during the outbreak, mostly on social media, and were predominantly negative. Higher levels of engagement were observed for information that was unverifiable (incidence relative risk [IRR] = 2.83; 95% confidence interval [CI], 1.33–0.62), posted during the outbreak (before: IRR = 0.15; 95% CI, 0.07–0.35; after: IRR = 0.46; 95% CI, 0.34-0.63), and with negative sentiment (IRR = 1.84; 95% CI, 1.23–2.75). Negatively toned posts were more likely to be misinformation (odds ratio [OR] = 9.59; 95% CI, 1.20–76.70) or unverified (OR = 5.03; 95% CI, 1.66–15.24).
Conclusions
Misinformation and unverified information during the outbreak showed clustering, with social media being particularly affected. This indepth assessment demonstrates the value of analyzing online “infodemics” to inform public health responses.

As part of our continued study on the chemical constituents of Willughbeia edulis stems, a new dimeric lignan named edulignan (1) was isolated from its EtOAc-soluble extract. Based on NMR spectroscopic interpretation, the planar structure of 1 has been suggested to have two 2-substituted 4-chromanone subunits with different stereochemical configurations. In addition, the MS/MS analysis of the products obtained by acidcatalyzed hydrolysis of 1 was supportive of its structure. Unfornatually, the new compound 1 did not show α-glucosidase inhibitory activity with an IC 50 value > 250 μM.

Background:
s/Aims: Liver transplantation (LT) provides a favorable outcome for patients with hepatocellular carcinoma (HCC) and was launched in Vietnam in 2004. In this study, we evaluated the short-term and long-term outcomes of LT and its risk factors.
Methods:
This retrospective study analyzed HCC patients who underwent LT at Viet Duc University hospital, Vietnam, from 01/2012–03/2022. The following data were gathered: demographics, virus infection, tumor characteristics, alpha-fetoprotein (AFP) level, Child-Pugh and MELD scores, selection criteria, type of LT, complications, 30-day mortality, and disease-free and overall survival (DFS and OS).
Results:
Fifty four patients were included, the mean age was 55.39 ± 8.46 years. Nearly 90% had hepatitis B virus-related HCC. The median (interquartile range) AFP level was 16.2 (88.7) ng/mL. The average MELD score was 10.57 ± 5.95; the rate of Child-Pugh A and B were 70.4% and 18.5%, respectively. Nearly 40% of the patients were within Milan criteria, brain-dead donor was 83.3%. Hepatic and portal vein thrombosis occurred in 0% and 1.9%, respectively; hepatic artery thrombosis 1.9%, biliary leakage 5.6%, and postoperative hemorrhage 3.7%. Ninety-day mortality was 5.6%. Five-year DFS and OS were 79.3% and 81.4%, respectively. MELD score and ChildPugh score were predictive factors for DFS and OS (p < 0.05). In multivariate analysis, Child-Pugh score was the only significant factor (p < 0.05).
Conclusions
In Vietnam, LT is an effective therapy for HCC with an acceptable complication rate, mortality rate, and good survival outcomes, and should be further encouraged.

Background:
s/Aims: Parenchymal-sparing anatomical hepatectomy (Ps–AH) based on portal ramification of the right anterior section (RAS) is a new technique to avoid unnecessarily transecting too much liver parenchyma, especially in cases of major anatomical hepatectomy.
Methods:
We prospectively assessed 26 patients with primary hepatic malignancies having undergone major Ps–AH based on portal ramification of the RAS from August 2018 to August 2022 (48 months). The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated.
Results:
Among the 26 patients analyzed, there was just one case that had intrahepatic cholangiocarcinoma The preoperative level of α– Fetoprotein was 25.2 ng/mL. All cases (100%) had Child–Pugh A liver function preoperatively. The ventral/dorsal RAS was preserved in 19 and 7 patients, respectively. The mean surgical margin was 6.2 mm. The mean surgical time was 228.5 minutes, while the mean blood loss was 255 mL. In pathology, 5 cases (19.2%) had microvascular invasion, and in the group of HCC patients, 92% of all cases had moderate or poor tumor differentiation. Six cases (23.1%) of postoperative complications were graded over III according to the Clavien–Dindo system, including in three patients resistant ascites or intra-abdominal abscess that required intervention.
Conclusions
Parenchymal-sparing anatomical hepatectomy based on portal ramification of the RAS to achieve R0-resection was safe and effective, with favorable short-term outcomes. This technique can be used widely in clinical practice.
