Back ground: The hypertension may lead the changes of the left ventricular geometry and the left ventricular diastolic dysfunction. There were many investigations about these abnormalities. Moreover, the treatment of the hypertensive patients with or without the left ventricular diastolic dysfunction is quite different. In Binh dinh general hospital, however, the left ventricular dysfuntion were neglected in practice. Thus, in this study, we evaluate the prevalence of these abnormalities in hypertensive patients. Subjects and method: We prospectively studied, from 6/2002 to 11/2003, 200 consecutive hypertensive patients admitted to the Internal Deparment at the Binh Dinh General Hospital. Echocardiography was performed on a Hewlett-Packard Image-Points with 2.5 and 3.5 MHz transducers. Measurements of the size of the ventricular walls are according to ASE. Doppler echocardiography is used to evaluate the characteristics of diastolic transmitral blood flow from the apical four-chaber view. The peak velocities of blood flow during early diastolic filling (E wave) and atrial contraction (A wave), the E-wave decelerating time and parameters of pulmonary venous flow revesal during atrial contraction are measured. The isovolumic relaxation time is measured from the apical-five chamber view. The diagnosis and classification of the left ventricular geometric changes and the abnormal diastolic filling patterns are based on the criteria of Devereux. Results: Prevalence of the left ventricular diastolic dysfunction was 61.5% of the hypertensive patients with the most frequent impaired relaxation pattern (48%). 72.5% of patients have the geometric changes in which the remodelling type consists of 47.5% concentric hypertrophy 25%.

Background: Laparoscopic cholecystectomy is the first laparoscopic surgery that was performed at Cho Ray hospital in September 1992. In 2005, Quang Tri general hospital has performed successfully the first case of laparoscopic appendectomy. Objectives: To access the preliminary results of application on endoscopic surgery in Quang Tri general hospital. Subjects and method: A prospective study was conducted on 140 patients with laparoscopic surgery or retroperitoneal surgery, was performed in Quang Tri general hospital from September, 2005 to April, 2006. Results:Among 140 patients was operated, there was only one case of postoperative intestinal obstructive complication (accounted for 0.7%), no case of death. Operative aged was between 11 and 70 years old. The average surgical time was 65 minutes for cholecystectomy, 35 minutes for appendectomy, 85 minutes for ureterolithotomy, 80 minutes for gynecological diseases. 2 cases of cholecystectomy and appendectomy changed open surgery. Conclusion: Laparoscopic surgery is a safe and effective method. It can be developed in provincial hospitals. Quang Tri general hospital has successful preliminary developed the new technique.

Raw or undercooked fish dishes are the major sources of human infection of fishborne trematodes (FBT) and the situation of metacercarial infection in fish greatly affect the prevalence in humans, especially those fish that are commonly used for raw consumption. To investigate the situation of infection with metacercaria of FBT in fish often used to prepare raw fish dishes by local people to assess the risk of infection to humans in Ninh Binh province, Vietnam. 345 fish belonging to five species of freshwater and one species of brackish water fish were collected from fishermen or small-scale fish dealers in Kim Son and Yen Khanh districts, Ninh Binh province between May 2017 and May 2018. Metacercaria of FBT was discovered by pepsin and hydrochloric acid digestion techniques and identified by the morphological and molecular analysis. Among examined fish, 44.06% infected with FBT metacercaria and the highest prevalence was in Cyprinus carpio (86.54%), Ctenopharyngodon idellus (78.43%) and Hypophthalmichthys molitrix (66.67%) while Konosirus punctatus – the brackish water fish – were free from infection. Three species of FBT were found; namely Haplorchis pumilio (accounting for 99.84% of collected metacercariae), Haplorchis taichui and Clonorchis sinensis. The average density was 1.06 metacercariae per gram of freshwater fish and the highest number was of C. idellus (6.38 cysts/gram) followed by Cirrhinus molitorella and C. carpio. Results of the study show the high prevalence of infection of FBT metacercariae among freshwater fish often used to prepare raw fish dishes in Ninh Binh province. These findings suggest the need for greater awareness of the risk from raw fish dishes among public health authorities and people.

As authorities braced for the arrival of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infrastructure investments and government directives prompted action in central Viet Nam to establish capacity for genomic surveillance sequencing. From 17 November 2021 to 7 January 2022, the Pasteur Institute in Nha Trang sequenced 162 specimens from 98 150 confirmed SARS-CoV-2 cases in the region collected from 8 November to 31 December 2021. Of these, all 127 domestic cases were identified as the B.1.617.2 (Delta) variant, whereas 92% (32/35) of imported cases were identified as the B.1.1.529 (Omicron) variant, all among international flight passengers. Patients were successfully isolated, enabling health-care workers to prepare for additional cases. Most (78%) of the 32 Omicron cases were fully vaccinated, suggesting continued importance of public health and social measures to control the spread of new variants.

Chronic inflammation results from excessive pro-inflammatory signaling and the failure to resolve the inflammatory reaction. Lipid mediators orchestrate both the initiation and resolution of inflammation. Switching from pro-inflammatory to pro-resolving lipid mediator biosynthesis is considered as efficient strategy to relieve chronic inflammation, though drug candidates exhibiting such features are unknown. Starting from a library of Vietnamese medical plant extracts, we identified isomers of the biflavanoid 8-methylsocotrin-4'-ol from
