109 patients (male: 60) with ages of 18-80 suffering the previous untreated acute haemorrhoid (congestive symptoms, no complication) administrated Ginkor fort at dose of 2 tablets x 3 times within the first 2 days and 2 tablets x 2 times a day within following 4 days. The results have shown that Ginkor fort had a rapid analgesic effect (55% of patient with pain free). The drug improved obviously the bleeding, even no bleeding (87.1%). 78.9% of patients had no pain at the sixth day. 94.5% of patients had obvious pain relief or bleeding reduction. There was a difference of these between the second day and sixth day. The itching, desire for movement and leakage improved among 80% of patient in the sixth day. The rate of good tolerance of Ginkor fort was 97.2%.

A prospective study of ambulatory CO2 laser hemorrhoidectomy. 295 consecutive patients (147 males, 148 females), mean age of 39 years (18-72), 97 cases of them (41 circumferential hemorrhoids, 56 piles) were strict follow-up from 3 months to one year. All had been operated by “restricted and pile-size hemorrhoidectomy” technique and performed with CO2¬ laser. Less operative bleeding (about 90% <20 ml), operating faster (average: 23.58 min), less painful (78.4% degree A + B), none post - op, hemorrhage, mean wound healing within 4 weeks, none late complication (anal fissure, fistula, deformity...) and recurrence. Hemorrhoidectomy using CO2 laser and author’s technique is safe, effective and no-hospitalization.

Purpose: Estimate the results of circumferential haemorrhoidectomy with laser CO2. Methods: A prospective study of 228 patients with circumferential haemorrhoids. All had been operated by "restricted and pilesize heamorrhoidectomy" technique and performed with laser CO2. Follow up 1 year to over 5 years. Results: less operative bleeding, operating faster, less post-op, painful and heamorrhage, mean wound healing within 24 days, short hospitalization, none late complication (anal fissura, fistula, whitehead deformity...) and recurrence. Conclusion: Circumferential heamorrhoidectomy using laser CO2 and author's technique is safe, effective and quick recover.

Background: The reduction of erythrocytes from cord blood is very need for long - term storage of C034 cells for transplantation. Reduced erythrocyte will reduces preservative blood volume, preservatives and freely HST when defrosting, so stem cells are better protected. Objectives: To study selection of the best centrifugal procedure to reduce maximal erythrocytes and lose minimal C034 cells from cord blood. Subjects and methods: 20 blood samples selected from 60 cord blood units was used for this study. The study was carried out through two steps. In the first step, the centrifugal speed was fixed and the centrifugal time was changed.In the second step, the centrifugal time was fixed, the centrifugal speed was changed. From collected results the best appropriate procedure to reduce erythrocytes from cord blood have been selected. Results: The procedure of gradient centrifuge with speed of 500g in 6 minutes isolated> 50% of erythrocytes, kept > 84% of CD34 cells and then centrifuge of 1000 g in 10 minutes reduced about 40% of volume of nuclear cell - suspension. Conclusion: The procedure can use for preparation of stem cell suspension from cord blood to storage in nitrogen liquid. \r\n', u'\r\n', u'

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.
