Submerged caves and marine lakes are two iconic and common ecosystems in Ha Long-Cat Ba area. However, their biological characteristics are poorly known since very limited studies have been conducted, The aim of this study was to investigate biodiversity in these ecosystems. Three submerged caves （hang Sang, hang Toi and Qua Bang） and three marine lakes （Dau Be, Ang Du and Qua Bang） were chosen for study. The results showed that organism communities in submerged caves were abundant with over 142 species found. The popular groups comprised sponge and soft coral which were distributed along the length of the caves. Several species with high economic value were widespread in the caves, including stone crab Myomenippe hardwickii, flower crab Portunus pelagicus, cone snails Trochus pyramis, shoemaker spinefoot Siganus sutor, snapper Lutjanus russellii. Species that permanently live in caves were not detected. In the lakes where water is well exchanged to the sea, coral reefs were found and they usually formed a narrow band around the lakes. Sandy beaches were often observed around the lakes at the depths of 0.5-2 m, containing specialty species as clam （Sanguinolaria diphos）, snout otter clam （Lutraria rhychaena）, sea cucumbers with high density （in Dau Be, Qua Bang）. There was no coral reef in the enclosed lake （Ang Du） because of low salinity.

An optimized formulation of a sustained release tablet of Gliclazide was developed. The use of Doptimal design with a polynomial statistical model to analyze dissolution data reduced the number of laboratory tests required to obtain an optimal dosage form. The final formulation contained 22 mg of Methocel®E15LV, 16.5 mg Methocel®E15 and 10.0 mg of Dibasic Calcium Phosphate per 30 mg Gliclazide sustained release tablet. Dissolution studies performed on tablets from 5000 tablet test batches released greater than 90 percent of loaded drug in eight hours. Drug release from the optimized tablets followed a pattern more closely similar to zero-order than other mechanisms of drug release tested. Storage of tablets in accelerated and ambient conditions for 6 and 12 months respectively did not alter any of the physico-chemical properties, drug release or the drug release rate compared to initial observations and dissolution data of the prepared tablets. The addition of potassium phosphate and monosodium phosphate to the tablet reduced the effect pH has on Gliclazide dissolution compared to the commercially available product.

通过对各向同性固结不排水试样进行循环三轴试验,研究了饱和重塑砂土的液化行为。试验采用恒幅正弦载荷,通过测量剪切模量、阻尼比、轴向应变和超孔隙水压力比的变化,评估了加载频率(分别为0.1、0.5、1.0 Hz)和压实度(分别为0.95、0.90和0.80)对砂土液化行为的影响。试验结果表明,对于压实度为0.95的砂样,在5000次加载循环中,0.1 Hz的加载频率对液化过程影响甚微;而对于压实度为0.90和0.80的砂样,此频率的影响显著。对于压实度为0.80的砂样,当频率增加到0.5 Hz时几乎一加载就直接发生液化。这表明增加加载频率会加快液化速度,而增加压实度则会减慢液化速度。因此,通过一系列的试验可以模拟现场砂土在不同频率下的动荷载条件。试验结果表明,饱和砂土的液化行为由以下因素决定:(1)试样的压实度越低,液化越容易发生;(2)加载频率越高,液化越容易发生;(3)循环轴向应变越大,发生液化所需的循环次数越少;(4)超孔隙水压力随加载循环次数增加,直至试样完全液化。

A clinical trial of measles and rubella combined vaccine (MR: MRVAC) produced by POLYVAC was conducted in Vietnam in 2016. A total of 756 subjects were enrolled, and 504 were allocated to MRVAC and 252 to control MR vaccine groups. Paired sera were obtained in 733, and the number of subjects was 403 aged 1 - 2 years, 164 aged 2 - 18 years, and 166 aged 18 - 45 years. Antibodies against measles and rubella viruses were evaluated by EIA. Most subjects had been immunized with a single dose of Expanded Programme on Immunization (EPI) measles vaccine at 9 months of age. Only 41 of 403 subjects aged 1 - 2 years were negative for measles antibody before vaccination, and all became seroconverted. A serological response of more than a 2-fold increase against measles was noted in 214 (47%, 95% CI;42.4% - 51.6%) of 458 initially seropositive individuals immunized with MRVAC and 65 (28%, 95% CI;22.3% - 33.8%) of 234 in the control group, and geometric mean titer (GMT) after vaccination was 25.49-5.60 in MRVAC and 25.03-5.24 in control group. Seroconversion against rubella virus after immunization with MRVAC was noted in 267 (98.5%, 95% CI;97.1% - 100%) of 271 initially seronegative subjects, similar to that after immunization with control group. GMT after immunization with MRVAC was 24.88-5.11 significantly lower than that after immunization with control vaccine (25.59-5.80). Most subject ≥ 2 years of age had rubella antibody because of MR vaccination campaign and no significant serological response was observed in initially seronegatives. MRVAC was highly immunogenic and safe vaccine and the domestic production of MR vaccine would contribute to realizing the goal of eliminating measles and rubella.

目的：通过联合调查正颌患者心理特征以及正颌患者术前术后的心理状态的变化和术后患者的满意程度。为正颌手术治疗中的提供心理评估参照,减少医疗纠纷。方法：选取2014年6月-2016年3月年在广西医科大学附属口腔医院正颌中心就诊,并接受正颌手术的严重颌面部畸形患者30例。分析正常人群(C)、术前1-2周(T1)、及手术后3个月(T2)。30例正颌手术患者和100名正常人群进行填写症状自评量表(Symptoms Checklist -90,SCL-90),EPQ (Eysenck Personality Questionnaire)问卷,在手术后3个月填写术后满意度问卷测评。采用SPSS19.0统计软件分析比较其不同时期的心理变化,P0.05),具有可比性。正颌患者术前组F2(强迫症)、F5(焦虑症)、F6(敌对症)、F7(恐怖症)、F8(偏执性)、F9(精神病性)因素的分数比较差异有统计学意义(P0.05)而两组分数较接近。在EPQ问卷调查显示E(外-内向)、N(神经质)因素比较分数差异有统计学意义(P<0.05);P(精神质)、N(神经质)因素明显降低,而E(外-内向)因素显著升高。结论：1、正颌手术前患者人格特征多为焦虑,忧郁,强迫症,人际关系敏感,具有精神质,提示手术前应对患者进行心理评估或干预。术后患者心理症状明显改善,提示正颌手术治疗既能改善患者的颌面面容,也能引起患者有益的心理改变。2、经过手术治疗后,颌面部畸形患者心理状态可以恢复至正常人群的心身健康水平。3. Scl-90,EPQ,术后满意度问卷调查的结合适用于颌面部畸形患者的心理学评估,合理的心理干预可以提高手术满意度。

任何形态存在的人类文化都与民族文化传统观念息息相关,作为宗教教育的佛教教育也不例外。发源于印度的佛教传入世界各国,随着国家民族的风土人情的不同与时代的进展,佛教教育呈现了五花八门的形式,僧团的生活方式与思想观念也各不相同。出于了解中越两国佛教教育的原因,笔者拿中越佛学院的本科班进行研究进行对比,首先阐述中国和越南佛学院教育的发展概况,大概地介绍从古代丛林教育模式转成现代佛学院教育模式的意义;其次分析中国佛学院和越南胡志明市佛教学院的调查结果以本科班的课程设置、生源情况、师资队伍、培养模式以及培养成效为主体分析对比之处,并深入剖析中越佛学院教育的差异,即从办学规模、培养模式、师资队伍的差异出发;最后探索中越两国佛教教育的差异形成原因,主要从办学方针、管理模式、师徒关系与民族观念的不同角度来观察。
