This study is aimed to investigate the activity of lymphocytes of recurrent spontaneous aborters, their response to phytohemagglutinin (PHA) mitogen was studied by comparing with that of normal pregnancy and normal non-pregnancy women. The results are as follows: there is no or a significant decrease of suppression of lymphoblast transformation in recurrent spontaneous abortion comparing to that of normal pregnancy women. It should be considered all of three parameters: absolute counts of OD with PHA, non-PHA and stimulation index as a general analysis for lymphoblast transformation.

We have studied 37 early pregnancy women, divided into 2 groups of: 22 women of recurrent spontaneous abortion and 15 women with normal pregnancy. By using micro lymphocytotoxicity technique in comparison between sera of the tested women and lymphocytes panel of 20 healthy women, this study shows higher incidence and levels of lymphocytotoxic antibodies in women with recurrent pregnancy failure than in normal women.

To study the immunologic characteristics of miscarriage, 34 women admitted with recurrent spontaneous abortion and 40 healthy women in the first trimester of pregnancy were investigated. The total results are as follows:-The total WBC count, especially granulocytes was raised significantly in RSA group.- No change was seen in the lympho T and lympho B cell numbers as well as lympho T CD4, lympho T CD8 cell numbers. However, the ratio CD4/CD8 was decreased in RSA group. Although it is not known if these changes are the cause or the effect, it would appear that immunologic abnormalities are associated with recurrent spontaneous abortion.

Background: DNA biosensor is based on micro-nano technologies aimed at developing a rapid diagnostic device of infectious diseases and diseases related to genetic change. Biosensors are compact size, high sensitivity and low cost\r\n', u'Objectives: To evaluate effect of biosensor in detecting specific gene fragments of Herpes Simplex virus type 1 and 2 (HSV)\r\n', u'Subjects and method: The electrical signals were recognized by means of transducer and from electrochemical detection of the hybridization between the probe 5\ufffd?AT CAC CGA CCC GGA GAG GGA C-3\ufffd?which were covalently immobilised onto the surface of micro electrodessensors in 3-aminopropyltri-ethoxysilance (APTS)-the conducting polymer matrix and the target (specific DNA sequences of HSV in the sample.\r\n', u'Results: The DNA sensor offers a very high sensitivity, a fast response time, less than 1 min with the DNA target concentration up to 1nM in aqueous media at room temperature.However, in order to detect target DNA in the real samples, samples must be extracted DNA, denatured DNA sequences from a double fiber to single fiber. The measurement should be done soon\r\n', u'Conclusion: The results show a large promise to develop quickly DNA sensors for widely application in bio-medical research \r\n', u'\r\n', u'

Ethmoid myoepithelial carcinoma is a rare tumor, with only 14 cases reported to date. This report discusses the largest tumor of this type ever recorded in the ethmoid region. The tumor caused extensive damage to facial structures, complicating treatment. The patient’s age and comorbidities increased the risk of intraoperative bleeding, presenting challenges to the complete removal of the tumor and the reconstruction of the damaged structures. To reduce the risk of intraoperative hemorrhage, shorten the surgery time, and manage potential heartrelated complications, arterial embolization was performed using gelatin sponges and coils. Definitive surgery was then carried out using a skin flap and mucosal flap to successfully reconstruct the defect. Postoperative radiotherapy was deemed unnecessary. The patient recovered well, with a satisfactory aesthetic outcome. No recurrence was observed during a 3-year follow-up period.

In this report we describe a new approach in HIV sentinel surveillance that was piloted in Viet Nam in 2009 and is currently being rolled out in all provinces. It comprises a brief behavioural questionnaire added to the HIV sentinel surveillance surveys conducted routinely among people who inject drugs, female sex workers and men who have sex with men. Timely reporting of data from this system has resulted in improvements to HIV prevention efforts for most at-risk populations.

Background: s/Aims: Hepatolithiasis and choledocholithiasis are frequent pathologies and unfortunately, with the current treatment strategies, the recurrence incidence is still high. This study aimed to assess the outcomes of laparoscopic choledochotomy using cholangioscopy via the percutaneous-choledochal tube for the treatment of hepatolithiasis and choledocholithiasis in Vietnamese patients. Methods: A cross-sectional study of patients with hepatolithiasis and/or choledocholithiasis who underwent laparoscopic choledochotomy using intraoperative cholangioscopy via percutaneous-choledochal tube at the Department of Hepatopancreatobiliary Surgery, 108 Military Central Hospital, from June 2017 to March 2020. Results: A total of 84 patients were analyzed. Most patients were females (56.0%) with a median age of 55.56 years. Among them, 41.8% of patients had previous abdominal operations, with 33.4% having choledochotomy. All patients underwent successful laparoscopic common bile duct exploration followed by T-tube drainage without needing to convert to open surgery. Most patients (64.3%) had both intrahepatic and extrahepatic stones. The rate of stones ≥ 10 mm in diameter was 64.3%. Biliary strictures were observed in 19.1% of patients during cholangioscopy. Complete removal of stones was achieved in 54.8% of patients. Intraoperative complications were encountered in two patients, but there was no need to change the strategy. The mean operating time was 121.85 ± 30.47 minutes.The early postoperative complication rate was 9.6%, and all patients were managed conservatively. The residual stones were removed through the T-tube tract by subsequent choledochoscopy in 34/38 patients, so the total success rate was 95.2%. Conclusions Laparoscopic choledochotomy combined with cholangioscopy through the percutaneous-choledochal tube is a safe and effective strategy for hepatolithiasis and/or choledocholithiasis, even in patients with a previous choledochotomy.
