Journal of Preventive Medicine 2003;13(6):29-33
Standard lyophylized rabid vaccine produced from CVS strain of Biopharma-Indonesia has met the criterion in terms of sterility, safety, efficacy (14.24 IU/ml), thermo-stability 37oC/month (5.4 IU/ml) and residual humidity (3.34%). Immune responsivity of the standard sample vaccine was determined by neutralizing method reaching 1/5 = 3.8 IU/ml; 1/25 = 1.7 IU/ml and 1/125 = 0.7 IU/ml

Background: Esophageal cancer is a common disease at Digestive Surgery Department of Binh Dan hospital. Surgical treatment is still a main procedure. Objectives: Study on a less invasive surgical technique in esophagectomy with supported thoracoscopy to provide a new esophageal cancer treatment. Subjects and method: Application on a new technique via thoracoscopy to esophagectomy totally in 6 patients (1 female, 5 males), aged 60 years on average, treated in Digestive Surgery Department of Binh Dan hospital from March 2006 to June 2006. Results: The average surgical time was 260 minutes. There was no event during operation. Postoperative complications included: 1 patient had to stitch abdominal wall after operative 7 days, 3 patients with pneumonia after successful operation, 2 patients with right pneumothorax, having to put siphonage. There was one case of death without related to operative technique. Conclusion: Esophagectomy is major operation that can be conducted via open surgery or laparoscopic surgery. Although small case studies, researchers found that laparoscopic surgery is a feasible technique, can be performed safely if the surgeons having experience in open surgery and good skills on laparoscopic surgery. However, thoracoscopic esophagectomy can only be considered as a surgical method, without an alternative method to traditional open surgery.

Background: Hue city is a cultural and tourism center of The middle and the whole country. Beside developing tourism services, food processing establishments, traditional specialities, eating and drinking services especially street food services more and more develop plentifully and multiform, satisfy daily demand of consumers. Objectives: Assessment on improvement level on some targets of street food safety and hygiene after 2 years intervention. Subjects and method: All street food processing establishments in 3 wards: V\u0129nh Ninh, Ph\xfa H\u1ed9i, V\ufffd?D\ufffd?of Hue city. Method: Cross-sectional study with comparison before and after intervention. Results: Kitchen utensils samples have met hygiene requirements and the proportion of food samples without borax both increase. The infection rate of bacteria in cook\ufffd?hands, kitchen utensils, cooked food were improved after 2 years carried out targeted model. Clean water for processing street food have not enough although 100% households use running water. The proportion of people were trained about food safety and hygiene knowledges and health examination increase. The situation of using food colourings and poisonous additives decrease remarkably. Salesclerks have more consciousness of preserving and covering food. 86,4% of food processing establishments have recycle bins obtain requirement to reduce polluted food. Conclusion: Street food is an important stage of food supplying network in 3 wards above. Somewhere having interest of Government and local authorities, Steering committee have efficient activities street food model develop conveniently.

The ability of the total extract from Physalis angulata; three fractions after partitioning with n-hexane, ethyl acetate (TBE), and water; and four withanolides (compounds 1 – 4) to phosphorylate 5'-adenosine monophosphate-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) in HepG2 cells was evaluated. The TBE fraction (50 μg/mL) activated p-ACC and p-AMPK expression most strongly. Compounds 1 – 4 (10 μM) upregulated p-ACC expression at different levels. Compound 4 induced the most significant changes in p-AMPK expression, followed by 1 and 2. Sterol regulatory element-binding proteins (SREBPs) play a functional role in the transcriptional regulation of the lipogenic pathway, including fatty acid synthase (FAS) and ACC. The effects of compounds 2 and 4 (10 μM) on FAS and SREBP-1c expression under high glucose conditions (30 mM) in HepG2 cells were evaluated further. Both dose-dependently inhibited FAS and SREBP-1c expression as well as lipid accumulation (1 – 10 μM) were compared to high-concentration glucose control, which upregulated FAS and SREBP-1c. These results suggest that compounds 2 and 4 upregulate AMPK, suppress FAS and SREBP-1c, and have potential effects on glucose and lipid metabolism.

Purpose:
Simulation teaching refers to the replication of real-life scenarios, enabling students to practice nursing skills and learn actively in a safe environment. It also helps students control their anxiety and fears when caring for real patients. This study investigated the relationships of Vietnamese nursing students’ self-confidence in clinical practice with their satisfaction and self-confidence in simulation-based practice.
Methods:
This cross-sectional descriptive study included 182 nursing students. The data collection included 2 separate stages with 2 main questionnaires. The Student Satisfaction and Self‐Confidence in Learning Scale was used to measure students’ satisfaction and self‐confidence after learning in the simulation room. The Confidence Scale was used to measure students’ self-confidence when first performing techniques on actual patients. Data were analyzed by descriptive and Pearson correlation statistics.
Results:
Students’ satisfaction and self-confidence during the simulation course were quite high (mean±standard deviation [SD], 4.06±0.48 and 4.11±0.46 out of 5.0, respectively). In contrast, their confidence when first practicing on a patient was moderate (mean±SD, 3.19±0.62 out of 5.0). Students’ satisfaction showed moderate and weak positive correlations with self-confidence in pre-clinical practice and in clinical practice (r=0.33, P<0.001 and r=0.26, P<0.001, respectively).
Conclusion
Simulation has become an effective teaching strategy that can help nursing students be well-prepared for clinical placements in Vietnam. An effective nursing education strategy is needed to enhance the satisfaction and self-confidence of nursing students in simulation and then in clinical practice to help achieve professional engagement and development.

Inflammation is a biological response caused by overactivation of the immune system and is controlled by immune cells via a variety of cytokines. The overproduction of pro-inflammatory cytokines enhances abnormal host immunity, resulting in diseases such as rheumatoid arthritis, cardiovascular disease, Alzheimer's disease, and cancer. Inhibiting the production of pro-inflammatory cytokines such as interleukin (IL)-12p40, IL-6, and tumor necrosis factor (TNF)-α might be one way to treat these conditions. Here, we investigated the anti-inflammatory activity of compounds isolated from Cimicifuga dahurica (Turcz.) Maxim., which is traditionally used as an antipyretic and analgesic in Korea. In primary cell culture assays, 12 compounds were found to inhibit the production of pro-inflammatory cytokines (IL-12p40, IL-6, and TNF-α) in vitro in bone marrow-derived dendritic cells stimulated with LPS.

Understanding the morphology of teeth is crucial in restorative dentistry in terms of restoring teeth’ anatomy, aesthetics, and function. Objectives: (1) this study describes an innovative method of teaching and learning tooth anatomy that applied shading techniques to 3D drawing the molar occlusal surfaces; (2) the study aims to survey learners’ opinions about the method’s effectiveness. Materials and methods: This study was conducted on 118 third-year dental students at the University of Medicine and Pharmacy, Hue University, from March to May 2022. The 3D occlusal surface drawing was developed and applied in teaching, and feedback was received from students. All statistical analysis was analyzed using SPSS version 26.0. Results: Instructions for 3D drawing were detailed and explained step-by-step, from forming to shading the occlusal surfaces. Subsequently, 57.3% - 90.9% of students self-assessed their proficiency in comprehending the characteristics of the occlusal anatomy. 73.3% - 95.8% of students agreed on the utility. 73.1% of students agreed to be willing to apply the 3D drawing method in learning other subjects. Conclusion: Instructions for 3D drawing were built step-by-step, from forming to shading the occlusal surfaces. After completing the course, a high percentage of students agreed on the advantages of this method. Further studies are needed to evaluate the effectiveness of the 3D drawing method in clinical practice
