Effects of artesunate in the combination of other antimalarial drugs (primaquine, mefloquine or chloroquine) on activities of some murine plasma enzymes were studied: (1) The combination of artesunate with primaquine induced significantly plasma activities of GOT, GPT, LDH, - HBDH, CK and CK- MB in comparison with artesunate alone; (2) The combination of artesunate with mefloquine also induced significantly plasma activities of GOT, GPT, LDH, -HBDH, CK and CK- MB in comparison with artesunate alone; (3) The companation of artesunate with chloroquine reduced slightly plasma activities of GOT, GPT, LDH, -HBDH, CK and CK-MB. The results obtained in the study suggest that the combination of artesunate with primaquine or mefloquine on murine cellular damage is synergistic, while the combination of artesunate with chloroquine is probably antagonistic

Screening by Test Pap smear is a preventative method and the best way for early detection for cancer, currently. After the Conference organized in May 2001, the gynaecologic cancers agreed with Bethesda system and give out the guidelines to clinical treatments: sample quality, common classification, results, automatic and depended tests, training and suggestion. Cervical cancer is an important healthy issuse which need to be screening because of its regular characteristics and have an effective treatment methods in the first early period, in the long-term preclinical period and can be able to detect. Using test Pap smear has quickly screen result, less invasive procedures, low cost and can be accepted widely

Background: Heparan-sufate interacting protetin (HIP) has been known to be up-regulated and expressed in various human cancer cell lines at both transcript and protein levels. HIP\u2019s expression was related to the differentiation status and cancer development. Objective: Using a semi-quantitative PCR method to determine HIP transcript levels in benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia (PIN) and prostate cancer tissues. Subjects and methods: 30 samples of BPH, 12 samples of high-grade PIN, and 40 samples of prostate cancer were collected from patients at Viet Duc Hospital and Friendship Hospital. Total RNA was extracted from BPH, PIN and prostate cancer tissues; cDNA synthesis by reverse transcript - polymerase chain reaction (RT - PCR); HIP transcript determination using semi-quantitative PCR. Results: There was significant difference in HIP transcript levels. HIP transcript was very highly up-regulated in the prostate cancer tissues. The up-regulation of HIP transcript was lower in PIN, and lowest in BPH. HIP transcript levels in benign samples were 1/2 and 2/3 compared with cancer and PIN samples, respectively (P< 0.05). These indicated that up-regulation of HIP transcript may be an early event in tumorigenesis. Conclusions: Levels of HIP transcript were different between tissues of prostate cancer, PIN, and BPH. HIP may be a marker for pre-cancer of the prostate.

Background: Heparansulfate Interacting Protein (HIP) is up-regulated in various human cancer cell lines at both transcript and protein levels. HIP expression is related to the differentiation status and cancer development. Objectives: To determine HIP in benign prostatic hyperplasia, prostatic intraepithelial neoplasia and prostate cancer tissues. Materials and method: Western blot method was used to determine HIP expression in 3 different types of prostate tissue, including 11 prostate cancer samples, 2 benign prostatic hyperplasia samples and 11 prostatic intraepithelial neoplasia samples. Results. HIP was particularly up-regulated in prostate cancer and prostatic intraepithelial neoplasia, indicating that up-regulation of HIP expression may be an early event in tumorgenesis. Conclusion: The expression of HIP was different between cancer, prostatic intraepithelial neoplasia tissue and benign prostatic hyperplasia. HIP may serve as a prognostic marker for prostate carcinoma.

Background: Recently, microplate almar blue assay has been used commonly in detecting gen related to tuberculosis drug resistance, which provides results after 5-7 days with lower cost compared to traditional methods. Objective: To evaluate the application of microplate almar blue assay for rapid detection of drug resistance of M. tuberculosis strains. Subject and Method: A microplate-based assay which uses Alamar blue reagent - an oxidation reduction dye (MABA), was used for the determination of the anti-tuberculosis drug (isoniazid-INH, rifampicine-RIF, streptomycine-STR and ethabuton=EMB) resistance of 96 M. tuberculosis strains isolated from Vietnamese patients in comparison to those obtained by conversional method. Result: MABA showed to have high sensitivity and specificity in testing the sensitivity to individual anti-tuberculosis drugs (from 82.4% for STR to 93.3% for - INH and from 82.5% for EMB to 98.4% for STR; respectively), as well as for the multi-drug resistant M.tuberculosis (86.4% of sensitivity), highly correlated with the result determined by proportion method. Conclusion: MABA reveals the advantage in shortening test time, in simple performance and lower cost compared with the conversional culture based methods.

Efonidipine, a calcium channel blocker, is widely used for the treatment of hypertension and cardiovascular diseases. In our preliminary study using structure-based virtual screening, efonidipine was identified as a potential inhibitor of c-Jun N-terminal kinase 3 (JNK3). Although its antihypertensive effect is widely known, the role of efonidipine in the central nervous system has remained elusive. The present study investigated the effects of efonidipine on the inflammation and cell migration induced by lipopolysaccharide (LPS) using murine BV2 and human HMC3 microglial cell lines and elucidated signaling molecules mediating its effects. We found that the phosphorylations of JNK and its downstream molecule c-Jun in LPS-treated BV2 cells were declined by efonidipine, confirming the finding from virtual screening. In addition, efonidipine inhibited the LPS-induced production of pro-inflammatory factors, including interleukin-1β (IL-1β) and nitric oxide. Similarly, the IL-1β production in LPS-treated HMC3 cells was also inhibited by efonidipine. Efonidipine markedly impeded cell migration stimulated by LPS in both cells. Furthermore, it inhibited the phosphorylation of inhibitor kappa B, thereby suppressing nuclear translocation of nuclear factor-κB (NF-κB) in LPS-treated BV2 cells. Taken together, efonidipine exerts anti-inflammatory and anti-migratory effects in LPS-treated microglial cells through inhibition of the JNK/NF-κB pathway. These findings imply that efonidipine may be a potential candidate for drug repositioning, with beneficial impacts on brain disorders associated with neuroinflammation.

Numerous studies have also revealed that students with a high level of Nomophobia have an increased risk of depression. However, few researchers are interested in examining how the association between nomophobia and depressive symptoms mediates loneliness and self-control. This study aimed to investigate, among Vietnamese High School Students, the association between nomophobia and depressive symptoms, specifically focusing on the role that loneliness and self-control play as potential mediators of that relationship. The Nomophobia Scale (NMP-Q), Depression Anxiety Stress Scale 21 (DASS-21), The UCLA loneliness scale version 3 (UCLA III), and The Brief Self-Control Scale (BSCS) were completed by 556 Vietnamese high school students. Using the PROCESS macro, mediation analyses were conducted to investigate the relationship between variables. According to our findings, nomophobia was positively associated with symptoms of depression, and loneliness and self-control partially mediated this relationship. It is suggested that methods for preventing claustrophobia and depressive symptoms be taken seriously in order to increase self-control and decrease loneliness.

Health financing has been considered as an important building block of a health system and has a key role in promoting universal health coverage in the Vietnam. This paper aims to describe the pattern of health expenditure, including total health expenditure and composition of health expenditure, over the last two decades in Vietnam. The paper mainly uses the data from Vietnam National Health Account and Vietnam Living Standards Survey. We also included data from other relevant published literature, reports and statistics about health care expenditure in Vietnam. The per capita health expenditure in Vietnam increased from US$ 14 in 1995 to US$ 86 in 2012. The total health expenditure as a share of GDP also rose from 5.2% in 1995 to 6.9% in 2012. Public health expenditure as percentage of government expenditure rose from 7.4% in 1995 to nearly 10% in 2012. The coverage of health insurance went up from 10% in 1995 to 68.5% in 2012. However, health financing in Vietnam was depending on private expenditures (57.4% in 2012). As a result, the proportion of households with catastrophic expenditure in 2012 was 4.2%. The rate of impoverishment in 2012 was 2.5%. To ensure equity and efficient goal of health system, policy actions for containing the health care out-of-pocket payments and their poverty impacts are urgently needed in Vietnam.
