Journal of Practical Medicine 2004;490(10):63-66
60 patients with chronic B hepatitis were treated at The Hospital No 108, using At Can Ninh, a preparation of traditional medicine. Some clinical symptoms were improved rapidly such as themia anotexia, jaundive, clark yellow urine. In comparing with control subjects, after 2-3 weeks treatment, SGOT, SGPT in blood were reduced more quickly. The preparation also reduce it Bs Ag, HBV- DNA level and serum converting rate was higher 14,3% verous 0% with p<0,05 after 3 months treatment. Some uncomfortable manifestation such as pylori pain and nausea in 2/30 patients were disappeared immediately after the cease of medicine.

Background: According to statistical data of the Vietnam Ministry of Health, there were 124,223 people with positive HIV, 23,661 AIDS patients and 13,649 AIDS- related deaths up to April 30th 2007. The major transmission route is injection. Objectives: (1) To compare the characteristics of drug use in users with different time. (2) To describe the health issues and health service access of young male drug users. Subjects and method: A cross-sectional survey was carried out using a combination of medical anthropology and epidemiology methods. 1.115 young male drug users in Ha Noi between September 2004 and September 2005 were divided into 4 groups of the equivalence number, but with different drug using history. Results and conclusion: The newer drug users (within 2 years) started using drug later than the older ones, more of them started using by injecting; they transfer from smoking/sniffing to injecting as well as trying and using more different types of drugs together in shorter time than others. The proportion of HIV (+) infection in these people was higher, which states the necessity of intervention to help them enhance their knowledge to prevent HIV infection amongst themselves. Mental health care is also needed for drug users, the demand for mental health care increases with the time of drug usage.

A new crinane-type alkaloid, 6-epihydroxypowelline (1), together with six known alkaloids, lycorine (2), 2-O-acetyllycorine (3), deacetylbowdensine (4), 1-epideacetylbowdensine (5), 8-demethyl-3-oxomaritidine (6), and (-)-marithamine (7) were isolated from the whole parts of the Crinum latifolium L. in Vietnam. The structure identification of all compounds was determined by 1D, 2D-NMR as well as HR-ESI-MS spectroscopic techniques. The absolute configuration of these compounds was established by the ECD data. In addition, in vitro inhibition of acetylcholinesterase (AChE) activities was assessed for all isolated alkaloids. All alkaloids had AChE inhibitory effects, with IC50 values ranging from 32.65 ± 2.72 to 212.76 ± 8.30 µM and compound 3 displayed the strongest inhibition of AChE, with IC50 values of 32.65 ± 2.72 µM (in comparison to the reference drug, galanthamine, which had an IC50 of 2.40 ± 0.45 µM).

Background: Human albumin was produced and used in many countries. Cohn's technique had been used to precipitate albumin from human plasma. This technique was easy and cheap and the quality of the product was good. In Vietnam, human albumin had to import, but the prices was very expensive. Vietnam was having good plasma in large quantity and high quality. That\u2019s why research on production plasma albumin was essential.\r\n", u"Objectives: This study aimed at using Cohn's technique improved by Drohan and Van - Aken to produce standard albumin from human plasma. Subjects and method: Human plasma detected VIII-factor was used for present study. Plasma \ufffd?albumin was precipitated by ethanol at low temperature and pH. The collected albumins have been liophilizated and storage at 40C. The quality and quantity of Albumin was evaluated by quantitative analysis and protein \ufffd?electrophoresis. Results: The 418g of albumin powder was produced from 16 liters of plasma detected F \ufffd?VIII. The quality of this albumin come up to standard (>95%) and quantity of albumin collected from one liter of this plasma was 26g. Conclusion: In the Vietnamese condition, the technique of Cohn can be used to produce standard albumin for treatment.\r\n", u'

Purpose:
This study aimed to determine the occurrence rate of gestational trophoblastic neoplasia (GTN) and its related factors in aged women with hydatidiform mole (HM) in Tu Du Hospital, Vietnam.
Materials and Methods:
This retrospective cohort study included 372 women aged ≥40 years with HM diagnosed through postabortion histopathological assessment in Tu Du Hospital from January 2016 to March 2019. Survival analysis was used for GTN cumulative rate estimation, log-rank test for group comparison, and Cox regression model for determining GTN-related factors.
Results:
After a 2-year follow-up, 123 patients were found to have GTN at a rate of 33.06% [95% confidence interval (CI): 28.30– 38.10]. GTN occurrence meant that the time was 4.15±2.93 weeks with peaks at week 2 and 3 after curettage abortion. The GTN rate was remarkably higher in the ≥46-year age group than in the 40-to-45-year age group [hazard ratio (HR)=1.63; 95%CI: 1.09– 2.44], as was the vaginal bleeding group compared to the non-bleeding group (HR=1.85; 95%CI: 1.16–2.96). Preventive hysterectomy and preventive chemotherapy plus hysterectomy in the intervention group reduced the GTN risk compared to the no intervention group at HRs of 0.16 (95%CI: 0.09–0.30) and 0.09 (95%CI: 0.04–0.21), respectively. Chemoprophylaxis failed to decrease the GTN risk when comparing the two groups.
Conclusion
Post-molar pregnancy GTN rate in aged patients was 33.06%, much higher than that of the general population. Preventive hysterectomy or chemoprophylaxis plus hysterectomy are effective treatment methods to support GTN risk reduction.

Background:
In recent years, there has been an increase in reports of perioral vascular complications resulting from filler injections, such as necrosis of the lip or alar rim, occlusion, and in severe cases, blindness. Conversely, the use of perioral arterial flaps is becoming more prevalent in the treatment of cleft lips, cancer, and trauma. A thorough understanding of perioral arteries is essential to minimize complications and maximize the success of these flaps. However, the course of the facial artery (FA) in the perioral region remains incompletely understood. The aim of this study was to describe the variations of the FA in the perioral region.
Methods:
We dissected 52 embalmed and formaldehyde-fixed Vietnamese cadavers. We then studied the size and distribution of perioral arteries in 102 specimens.
Results:
The superior labial artery (SLA) was the most common branch, occurring in 87.25% of cadavers, followed by the inferior labial artery (ILA) at 78.43%. The SLA primarily originated above the mouth corner (cheilion), accounting for 91.01% of cases, and predominantly exhibited a tortuous course within the submucosa (78.65%). The ILA’s branching pattern varied, but it was primarily located below the cheilion (91.25%). The ILA also followed a twisted path, generally within the submucosa. The ILA exhibited two patterns: the typical pattern, distributed at the vermilion border of the lower lip (8.82%), and the horizontal labiomental artery pattern, which ran horizontally in the middle of the lower lip area (69.61%). At their origin, the SLA and ILA had average external diameters of 1.29 mm and 1.28 mm, respectively.
Conclusion
Numerous anatomical variations in the FA in the perioral region were found. A detailed anatomic description, suggested landmarks, and angiography before the procedure will be useful to help doctors avoid complications.
