    Abstract: Fucoidan is a sulfated polysaccharide derived from brown seaweed, and it has been applied in pharmaceutical fields.Recently, the trend of applying advanced extraction techniques and optimizing extraction conditions has been particularly interested in order to achieve high extraction yield. In this study, response surface methodology (RSM) were employed to optimise the ultrasound-assisted extraction of fucoidan from brown seaweed Tubinaria decurrens. The impacts of three independent variables, including extraction temperatures (X1: 50-80°C), extraction time (X2: 30-60 min), and ultrasound power (X3: 40-100%) was investigated through Box-Behnken experimental design. The results showed that the optimised condition was at extraction temperatures of 70°C, extraction time of 53 min, and ultrasound power of 90%. Under this optimised condition, the extraction yield was 4.28% and close to the predicted yield of 4.34%.

    Abstract: Background: In traditional medicine, “kidney dominate reproduction”, kidney deficiency is the main cause of polycystic ovary syndrome and infertility. Objective: To survey on kidney organ function characteristics according to traditional medicine and find out some related factors in infertile patients with polycystic ovary syndrome. Method: This cross-sectional descriptive study recruited 110 infertile women with polycystic ovary syndrome who visited the Center for Reproductive Endocrinology and Infertility, Hue University of Medicine and Pharmacy Hospital. Result: The symptoms of kidney Jing/Qi deficiency accounted for a high percentage ( 〉 60%) and have the highest average score (5.3 ± 2.5). Kidney Yin deficiency syndrome accounted for 49.1%, kidney Yang deficiency syndrome 36.4% and kidney Yin Yang deficiency syndrome 20.9%, the average score of kidney Yin was higher than that of kidney Yang. There was difference in kidney Yang score between the body types, in kidney Yin score, kidney Yang and the presence of kidney Yin Yang deficiency syndrome between infertility types. Conclusion: Symptoms in the kidney Yin deficiency syndrome and kidney Yang deficiency syndrome appeared at a rather high rate. Kidney Yin deficiency syndrome accounted for the highest rate, followed by kidney Yang deficiency syndrome and kidney Yin Yang deficiency syndrome. Kidney Yang score in overweight and obese groups were higher than in lean and normal groups. Secondary infertility has higher kidney Yin score and kidney Yang score than primary one. Key words: Kidney organ, traditional medicine, polycystic ovary syndrome, infertility

    Abstract: The literature shows that the relationship between state ownership and corporate investment is debatable. This study examines this relationship in Vietnam as a transitional economy. Our sample consists of 4,680 observations from 2009 to 2020. Using fixed effects and random effects for panel data, random effects Tobit, and pooled OLS, we find that state ownership decreases investment expenditures. Moreover, this negative impact is stronger if the firms are financially unconstrained. Our results indicate that weak corporate governance and soft budget constraints arising from state ownership may fail to determine investment decisions. A government’s negative attitude toward risk and conservatism may effectively affect corporate investment.

    Abstract: In this paper, we calculate the diagonal contributions W(R, s = 0) of the imaginary part of the microsopic optical potential at negatives energies, where W(R, s) =Σlj(2j+1)/4π Im∆Σlj(r, r′, ω), with R = 1/2.(r + r′) corresponding to the radius and shape ofIm∆Σ, and s = r - r′. To do it, the microscopic optical potential has been calculatedby using the nuclear structure approach which is based on the Green function method. The coupling between the particle and collective phonon has been performed to calculate the dynamic part of the optical potential. It has been found that the imaginary part at negative energies is very small as expected. The calculated W(R, 0) is maximum on the surface and deacreases to zero in the interior.

    Abstract: Background: Qi, blood, Yin and Yang are especially important elements of the human body. However, in the elderly, along with the aging, the blood and qi in the body decrease there by leading to the imbalance of Yin, Yang, Qi, blood, which manifests itself into diseases. The research on the clinical features of the elderly of the Qi, blood, Yin and Yang has many limitations. Objective: Survey on characteristics of qi, blood, yin, yang of elderly and find out several factors related to the Qi, blood, Yin and Yang. Method: Descriptive crosssectional study on 280 elderly people who come for treatment at Thua Thien Hue Traditional Medicine Hospital. Result: The Yang deficiency is 55.4%, the blood deficiency is 55.0%, the Yin deficiency is 32.1%, the Qi deficiency is 26.1%. There is a relationship between the Qi blood deficiency, the Qi Yin deficiency, the Qi blood Yin and Yang deficiency with the gender; between blood deficiency, Yin deficiency, Yin Yang deficiency, Qi Yin deficiency, Yin blood deficiency, Qi blood Yin Yang deficiency with insomnia; between blood deficiency, Yin Yang deficiency, Yin blood deficiency, Qi blood Yin Yang deficiency with habitus (p 〈 0.05). Conclusion: Qi deficiency, blood deficiency, Yin deficiency, Yang deficiency are common syndromes, Yang deficiency accounts for the highest percentage followed by blood deficiency; Qi blood deficiency, the Qi Yin deficiency, the Qi blood Yin and Yang deficiency is more common in women than in men; insomnia is the clinical manifestation related to the status of Qi, blood, Yin and Yang. Key words: Qi Deficiency, Blood Deficiency, Yin Deficiency, Yang Deficiency, elderly.

    Abstract: Background: The theory of Qi, blood, yin, and yang is one of the significant dialectics in the traditional practice of medicine in the elderly. Objective: Research on the reliability, sensitivity and specificity of the abridged Vietnamese version of the Qi Blood Yin Yang Deficiency Pattern (QBYYDP) questionnaire on the elderly. Method: A descriptive cross-sectional study was conducted on 290 elderly who came for treatment at Thua Thien Hue Traditional Medicine Hospital. Result: The abridged Vietnamese version of the Qi Blood Yin Yang Deficiency Pattern (QBYYDP) questionnaire on the elderly consists of 27 questions (male: 26 questions and female: 27 questions) with Cronbach’s Alpha of 0.895 (male) and 0.871 (female), the sensitivities Qi deficiency region, Blood deficiency region, Yin deficiency region, and Yang deficiency region were: 62.50%, 66.67%, 44.12%, 37.5% (male), 63.04% (female), respectively; the specificity 95.9%, 50.89%, 76.95%, 69.49% (male) and 75.74% (female), respectively, the area under the ROC curve of the questionnaires were 〉 0.6. Conclusion: The abridged Vietnamese version of the Qi Blood Yin Yang Deficiency Pattern (QBYYDP) questionnaire on the elderly with high consistency and reliability assessed through Cronbach’s Alpha coefficient. The value of the Qi deficiency region has a high specificity and is distinguishable between two groups with diseased and non-diseased well. Although it is possible to take the Blood deficiency region, Yin deficiency region, and Yang deficiency region for clinical reference, the sensitivity and specificity are low, and the ability to distinguish the disease is moderate or poor. Key words: reliability, validity, questionnaire, Qi Blood Yin Yang deficiency pattern, the elderly.
