1.Study on the clinical characteristics, examination of cytology and the anatopathology of metastasis cervical lymph nodes in head – neck neoplasms and unknown metastasis cervical lymph nodes
Journal of Practical Medicine 2005;515(7):44-48
Study on 171 patients who had metastasis cervical lymph nodes (132 males, 39 females) caused by head – neck neoplasm or unknown causes were diagnosed and surgery treated at Hospital K, Ha Noi from Dec 1998 to Jun 2001. The results showed that: the clinical features can used to evaluate metastasis and to be basic for treatment strategy such as: site, size, density, number, mobility, characters of skin on node’s surface. It is emphasized that cytology biopsy is very effective method in diagnosing metastasis cervical lymph nodes.

2.Morphological study of cervical lymph node metastases of unknown primary tumor
Journal of Vietnamese Medicine 2001;263(9):92-96
We report the results of morphological study of cervical lymph node metastasis of unknown primary tumor at K Hospital from January 1999 to December 2000. Cytological diagnosis had true positive rate in 69.4% false positive rate in 16.6% and false negative rate in 13.8%. The most common histological types are undifferentiated carcinoma (36.3%) and nonkeratinizing squamous cell carcinoma (30%). Immunohistological study is very helpful in the confirmation of epithelial nature of undifferentiated carcinoma

Geographical and racial factors constitute important distinctions between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C), but no study has been conducted in Vietnam. Forty-one children with KD from January 2018 to July 2020 and 42 with KD/MIS-C from August 2020 to December 2022 were included in this study. Of the patients, 52.3% were aged between 12 and 35 months. Only two were aged over 5 years, and both were belong to the KD/MIS-C group. A 59.5% of the patients were male. Apart from fever, all symptoms tended to be more frequent in patients with KD/MIS-C. The prevalence of diffuse skin rash, hand and foot edema or erythema and gastrointestinal signs was significantly higher in patients hospitalized with KD/MIS-C. There was no significant difference in laboratory findings between the two groups. Coronary artery dilation was more frequently observed in patients with KD/MIS-C compared to those with KD (40.5% vs. 14.6%, P = 0.009).

Objective: To examine the in vitro and in vivo anti-inflammatory effects of the alkaloid enriched extract (ELA) from the roots of Eurycoma longifolia. Methods: The in vitro antiinflammatory effects of ELA were evaluated by examining its inhibitory activities against nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2) expressions in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The level of NO produced in the culture media was determined by Griess method. The iNOS and COX-2 protein expressions were analyzed by Western blot. The in vivo effect of ELA was evaluated on LPS-induced septic shock in mice model. Mice mortality was monitored for 5 days after injection of LPS. The chemical contents of the ELA were determined by using various chromatographic and spectroscopic techniques. Results: The ELA was found to exhibit a significant anti-inflammatory effect in both in vitro and in vivo models. The results demonstrated that ELA dose-dependently inhibited LPS-induced NO production as well as the protein iNOS and COX-2 expressions. In the septic shock model, ELA dose-dependently protected mice from LPS-induced mortality. Further study on the isolated components of ELA indicated that 9,10-dimethoxycanthin-6-one may contribute significantly to the anti-inflammatory effects of the extract. Conclusions: These results suggest that ELA exhibits the anti-inflammatory activity via suppression of pro-inflammatory mediators such as NO, iNOS, and COX-2 and protects mice from LPS-induced mortality in septic shock model.
