Nguyen Quoc Hung,Vu Van Nam,Le Thi Minh Thu 세계문화관광학회 2019 International Journal of Culture and tourism Resea Vol.12 No.1
If someone has a chance to come to Phum Soai hamlet in Chau Phong commune, Tan Chau town, An Giang province, they will have the opportunity to experience the interesting things about the life of the Muslim Cham community for hundreds of years. It is like a living museum, preserving traditional livelihoods, religious life, religious architectural works of Cham Muslims for generations. Within the scope of this article, the authors will summarize the results from the field trip at Phum Soai hamlet so that those who are interested have more information about life, culture and future development of the Islam Cham community here.

Aims: Laparoscopic pancreaticoduodenectomy (LPD) is considered as a safe and effective procedure in well - selected patients and appropriate surgical technique. Our aim is to evaluate suitability of using protocol for LPD in treatment of periampullary cancer at a single team. Methods: case series Results: Indication for LPD included 37 cases with resectable tumors which were classified basing on NCCN. All witness evaluation risk of complications with PREPARE score, ASA and evaluation risk of postoperative pancreatic fistula (POPF) with FRS classification. There were 2 open conversions because of vein resections, accounting for 5.4%. Standard lymphadenectomy was performed in all of 37 cases. In term of PREPARE score, major complications (Clavien - Dindo >= III) were 17.8%, 0% and 0% (5/28, 0/5 and 0/2 cases) in low risk, intermediate risk and high risk group, respectively. All of cases had ASA I or II. POPF happened 11.1% (1/9), 4.1% (1/24) and 50% (1/2) in low risk, intermediate risk and high risk group, respectively. Frozen section was needed for R0 margin. Retrieved lymph nodes was 8 - 18 with 12 lymph nodes in average. Conclusions: Indication for LPD with resectable tumors is acceptable. ASA I or II is a safe measure to select patient for LPD. FRS classification shows appropriation to evaluate risk of POPF.

In the present work, ZnO/g-C₃N₄/biochar was prepared, and it was used for visible-light driven photocatalytic degradation of some colorants (methylene blue, rhodamine B, methyl orange) and some antibiotics (doxycycline, ciprofloxacin, amoxicilline). Biochar was prepared by pyrolysing Phragmites australis biomass. The ZnO/g-C₃N₄/biochar composite was synthesized with the alkaline hydrolysis method. The obtained materials were characterized by X-ray diffraction, scanning electron microscopy, transition electron microscopy, energy dispersive X-ray/elemental mapping, ultraviolet-visible-diffuse reflectance spectroscopy, photoluminescence spectroscopy, nitrogen adsorption/desorption isotherms and X-ray photoelectron spectroscopy. The results show that ZnO nanoparticles with a large surface area are highly dispersed on the g-C₃N₄ particle surface and biochar. The composite exhibits superior photocatalytic degradation ability toward doxycycline, a broad-spectrum antibiotic of the tetracycline compared with individual components (ZnO or g-C₃N₄) and satisfies stability after six treatment cycles. The kinetics and degradation mechanisms of doxycyline were also addressed. In addition, the present catalyst also exhibits the photocatalytic degradation of methylene blue, rhodamine B, methyl orange, ciprofloxacin and amoxicillin in visible-light regions.

A novel dosage form integrating solid dispersion(SD) in orally disintegrating tablets (ODTs) wasdeveloped and optimized by the face-centered centralcomposite design to improve poorly soluble property andslow onset action time of felodipine (Fel). SD of Fel andhydroxypropyl methylcellulose E6 was prepared by solventevaporation method. Differential scanning calorimetry andfourier transforms infrared spectroscopy indicated that Feltransformed from crystalline to amorphous state by theformation of hydrogen bond between –N–H in Fel and O–Rin HPMC. The accelerated stability test in 45 C, 75 % RHdemonstrated that the optimized SD was stable in terms ofthe dissolution rate of Fel and thermodynamic property. The ODTs containing SD (Fel:HPMC E6 = 1:3) wereprepared by direct compression technique. The face-centeredcentral composite design with the ODT-SD wasemployed to investigate the effect of mannitol (X1),crospovidone XL (X2) on the ODT-SD disintegration time(Y1), % Fel released after 5 min (Y2) and the ODT-SDfriability (Y3). ANOVA test showed that X2 and X2 * X2had a significant effect on the ODT-SD disintegration time(p\0.05). Meanwhile, the dissolution rate of Fel after5 min did not remarkably depend on any independentvariables (p[0.05). The ODT-SD friability was substantiallyproportional to the amount of mannitol (X1)(p\0.05). The optimized ODT-SD disintegration time, %Fel released after 5 min, and friability were 27.67 s, 88.35and 0.48 %, respectively.

Medicinal plants constitute an important sourceof potential therapeutic agents for diabetes. The purpose ofpresent study is to investigate the effect of root extract ofRosa rugosa Thunb. on inhibition of sucrase related todiabetes mellitus (DM). Bioassay-guided fractionation ofthe methanol extract led to the identification of 13 triterpenoidsaponins (1–13). Their structures were elucidatedon the basis of extensive spectroscopic analysis, including1D, 2D NMR, and MS. The n-butanol fraction showedpotent rat intestinal sucrase inhibitory activity with value of87.62 ± 5.84 % inhibition compared to the positive controlacarbose (50.96 ± 2.97 % inhibition at 0.02 mM). Subsequently, compounds 11–13 (1.0 mM) exhibited significantsucrase inhibitory activity, with inhibition percentagevalues of 41.17 ± 3.52, 46.80 ± 4.00, and39.39 ± 4.19 %, respectively. Whereas, compounds 2–6,8, and 10 showed moderate sucrase inhibitory activity(ranging from 13.26 ± 7.00 to 32.08 ± 6.04 % inhibition)at a same concentration. The data provide a starting pointfor creating new sucrase inhibitors, which may be usefulfor the development of effective therapies for the treatmentof DM.

Thirty-two methanol extracts of thirty-one Vietnamese medicinal plants were evaluated for the cytotoxic activity against five human cancer cell lines, including A549, MCF-7, HT 1080, Huh-7, and HepG2. Of these, the nine extracts of Acanthopanax trifoliatus (4), Acanthopanax gracilistylus (5), Siegesbeckia orientalis (10), Betula alnoides (11), Passiflora edulis (18), Zanthoxylum simulans (leaf, 23), Adenosma caeruleum (26), Solanum verbascifolium (29), and Alpinia malaccensis (31), exhibited high potent cytotoxic activity showing a certain degree of selectivity against the different cell types, with IC50 values ranging from 2.1 to 3.8 mg/mL.

A new compound, 3β-acetoxylanosta-7,9(11),24-triene-26-al (3), and seven known compounds (1 – 2 and 4 – 8) were isolated from Ganoderma tropicum (Jung.) Bres. collected in Tay Nguyen, Vietnam. The structures of these compounds were determined by one- and two-dimensional nuclear magnetic resonance spectroscopy, electrospray ionization mass spectrometry (ESI-MS), and high-resolution ESI-MS, and by comparison with literature data. All of the isolated compounds were tested for nitroblue tetrazolium (NBT) reduction activity in Saccharomyces cerevisiae-stimulated RAW 246.7 cells. Among them, compounds 2 – 4 and 6 – 8 enhanced the NBT reduction in a dose-dependent manner.

In vitro in screening test aiming to find monoamine oxidase (MAO) inhibitors from Vietnamese medicinal plants, the MeOH extracts of seventeen medicinal plants were tested for the inhibitory effects on monoamine oxidase activity. MAO was purified from mouse brain and its activity was determined by fluorospectrophotometer using kynuramine as a substrate. Five MeOH extracts of medicinal plants including Cnidium monnineri showed quite strong inhibitory effects at the concentration of 250 ㎍/㎖. Six MeOH extracts of herbs including Astragalus membranaceus showed moderate inhibitory effects on this enzyme. Seven medicinal plants which showed good inhibitory effects on MAO were fractionated with CH_2Cl_2, EtOAc, BuOH and H_2O, successively. They were investigated for the inhibitory effects on MAO.
