ABSTRACT

Zexietang is derived from Jingui Yaolue (《金匮要略》), which is composed of Alismatis Rhizoma and Atractylodis Macrocephalae Rhizoma, and has the effect of inducing diuresis and invigorating the spleen to produce water. Compared with western medicine in the treatment of related diseases, Zexietang can not only improve the curative effect, but also reduce the occurrence of adverse reactions, so as to achieve long-term stable administration. The authors sorted out and analyzed the chemical composition, pharmacological effect and clinical application of Zexietang in recent years. It was found that the main active components of Zexietang were alismol A and B, 23-acetyl-alismol B and C, atractylenolides (atractylenolide Ⅰ, Ⅱ, Ⅲ) and polysaccharides. Pharmacological experiments showed that they had diuretic, hypolipidemic, anti-inflammatory and others. And it can be used in the treatment of hypertension, hyperlipidemia, vertigo, cerebral vascular insufficiency and other diseases combined with other Chinese materia medica, and the curative effect is obvious. By summarizing the research status of Zexietang in recent years, its active components and pharmacological mechanism can be further clarified, which provides the basis for the clinical application of Zexietang and guides the direction of its further research.

ABSTRACT

The small size, moderate drug loading, and targeting properties of nano-preparations make them can be excellent delivery tools for drugs, genes or proteins crossing the cell or blood-brain barrier (BBB). Currently, facilitating drug crossing BBB with innovative nano-drug delivery systems is considered as a strategic approach for the prevention, diagnosis and treatment of central nervous system (CNS) diseases. However, with the deepening of the research, the adverse reactions and toxicity of nanocarriers have gradually attracted the attention of researchers. Based on this, this paper summarized the situation of BBB-penetrating targeted nano-preparations at home and abroad in recent years from the perspective of classification of types and properties of nanocarriers, and analyzed the advantages and disadvantages of each carrier. The results showed that nano-preparations with active ingredients of traditional Chinese medicine (TCM) as carriers have become a promising way of cancer treatment, but the complexity and diversity of TCM components limited its application to a certain extent. Further studies should be strengthened to lay a foundation for the application and development of TCM nano-preparations in the field of CNS diseases.

ABSTRACT

The paclitaxel-loaded and folic acid-modified poly(lactic-co-glycolic acid) nano-micelles(PTX@FA-PLGA-NMs) were prepared by the emulsion solvent evaporation method, and the parameters of paclitaxel-loaded nano-micelles were optimized with the particle size and PDI as evaluation indexes. The morphology of the nano-micelles was observed by transmission electron microscopy(TEM), and the stability, drug loading and encapsulation efficiency were systematically investigated. In vitro experiments were performed to study the cytotoxic effects of nano-micelles, apoptosis, and cellular uptake. Under the optimal parameters, the nano-micelles showed the particle size of(125.3±1.2) nm, the PDI of 0.086±0.026, the zeta potential of(-20.0±3.8) mV, the drug loading of 7.2%±0.75%, and the encapsulation efficiency of 50.7%±1.0%. The nano-micelles were in regular spherical shape as observed by TEM. The blank FA-PLGA-NMs exhibited almost no inhibitory effect on the proliferation and growth of tumor cells, while the drug-loaded nano-micelles and free PTX exhibited significant inhibitory effects. The IC_(50) of PTX@FA-PLGA-NMs and PTX was 0.56 μg·mL~(-1) and 0.66 μg·mL~(-1), respectively. The paclitaxel-loaded nano-micelles were potent in inhibiting cell migration as assessed by the scratch assay. PTX@FA-PLGA-NMs had good pro-apoptotic effect on cervical cancer HeLa cells and significantly promoted the uptake of HeLa cells. The results of in vitro experiments suggested that PTX@FA-PLGA-NMs could target and treat cervical cancer HeLa cells. Therefore, as nanodrug carriers, PTX@FA-PLGA-NMs with anti-cancer activity are a promising nano-system for improving the-rapeutic effects on tumors.

ABSTRACT

Objective::To investigate the pharmacodynamics of volatile oil in couplet medicines of Moslae Herba and Pogostemonis Herba, to establish a method for simultaneous determination of three essential ingredients (thymol, carvacrol and patchouli alcohol) in volatile oil of the couplet medicines by gas chromatography (GC), to optimize the preparation process of β-cyclodextrin (β-CD) inclusion complex of volatile oil in the couplet medicines and to confirm the formation of the inclusion complex. Method::An in vitro inflammatory response model was established by hyaluronidase activity inhibition test in order to detect the anti-inflammatory activity of the volatile oil. Also, the antioxidant activity of the volatile oil was assessed by 1, 1-diphenyl-2-trinitrophenylhydrazine (DPPH) free radical scavenging method. The inclusion of volatile oil in couplet medicines of Moslae Herba and Pogostemonis Herba was prepared by scaturated aqueous solution method, colloid milling method and grinding method, respectively. GC was used to determine the contents of thymol, carvacrol and patchouli alcohol in volatile oil for optimizing extraction and inclusion processes of volatile oil. Scanning electron microscope, infrared spectroscopy, thermal differential analysis, and X-ray diffraction (XRD) were used to verify the formation of the inclusion complex. Result::The volatile oil not only inhibited hyaluronidase activity to a certain extent, but also eliminated DPPH and increased with the increase of concentration. There was a good linear relationship between the peak area and concentration of thymol, carvacrol and patchouli alcohol at 0.021 3-0.426, 0.020 04-0.400 8, 0.022 6-0.452 g·L-1 (R2>0.999), respectively. Their recoveries were 99.59%(RSD 1.6%), 100.15%(RSD 1.5%), 100.70%(RSD 1.4%), respectively. The colloid milling method was optimized, and the formation of the inclusion complex was verified by the aforementioned methods. Conclusion::The volatile oil in couplet medicines of Moslae Herba and Pogostemonis Herba has certain anti-inflammatory activity and anti-oxidation ability. The colloid milling method was the best inclusion process for the volatile oil. The established GC has the advantages of simple, sensitive, accurate, reliable and reproducible, which can meet the requirements of simultaneous determination of thymol, carvacrol and patchouli alcohol in the inclusion complex.

ABSTRACT

Objective To explore the application of Framingham Stroke Risk Profile in elderly people. Methods A total of 5 148 people aged 55 years and older who received physical examination in a community were enrolled.Information of their healthy status and risk factors were collected by interview using a questionnaire.Height, weight, waist circumference (WC), and blood pressure as well as fasting plasma glucose ( FPG) , and serum lipid were measured. Results The average 10-year probabilities of stroke in elderly people were 9.79% in men and 6.20% in women ( P <0.05).Besides aging factor, higher risk probability in men might be related to their higher proportions of smoking and atrial fibrillation. In addition to blood pressure and FPG which were variables associated with risk profile, WC/height ratio ( WHR) and serum triglyceride level were associated with increased risk of stroke estimated by stroke risk profile (OR=1.598, 95%CI:1.371~1.864;OR=1.487, 95%CI:1.225~1.783), respectively. Conclusion Besides factors which had been included by risk profile, it is important to pay attention to weight control and triglyceride level.For elderly male, to quit smoking is an important measure that decreases their risk of stroke.

ABSTRACT

Serglycin belongs to a family of small proteoglycans with Ser-Gly dipeptide repeats, and it is modified with different types of glycosaminoglycan side chains. Intracellular serglycin affects the retention and secretion of proteases, chemokines, or other cytokines by physically binding to these factors in secretory granules. Extracellular serglycin has been found to be released by several types of human cancer cells, and it is able to promote the metastasis of nasopharyngeal carcinoma cells. Serglycin can bind to CD44, which is another glycoprotein located in cellular membrane. Serglycin's function of promoting cancer cell metastasis depends on glycosylation of its core protein, which can be achieved by autocrine as well as paracrine secretion mechanisms. Further investigations are warranted to elucidate serglycin signaling mechanisms with the goal of targeting them to prevent cancer cell metastasis.

ABSTRACT

Enhanced green fluorescent protein( EGFP), myc epitope and polyhistidine metal-binding tag are often used as a marker for recombinant fusion protein in many gene expression vectors, each marker has its own function, EGFP emits green fluorescence for direct detection, myc epitope facilitates recombinant fusion protein detection using its antibodies, polyhistidine tag allows purification of recombinant fusion protein using resin.Hitherto, no a plasmid vector can integrate all of these functions. In this study we constructed a novel eukaryotic expressive plasmid, designated as pcDNA6/myc-his-EGFP B, which integrated the functions of EGFP, myc epitope and polyhistidine tag. Importantly, a linker octo - peptide in N terminal of EGFP was designed using LINKER program. A DNA fragment encoding a putative protein containing a signal peptide of human interleukin 2(IL-2) in N terminal was cloned into pcDNA6/myc-his-EGFP B in frame with the C-terminal peptide to construct pMHES. 2.2.15 Cells were transfected with pcDNA6/myc-his-EGFP B and pMHES, and Balb/c mice were intravenously injected with pcDNA6/myc-his-EGFP B by tails, results revealed that both of the plasmids worked in 2.2.15 Cells and livers of Balb/c mice. Assuming gene of the IL-2 was inserted into pcDNA6/myc-his -EGFP B in frame with EGFP, myc and 6 × His, three-dimensional structure for this putative expression product was simulated using Modeller8V2, results revealed that IL-2, EGFP, myc and 6 × his did not interfere each other and octo- peptide linker owned certain flexibility. The results suggest that pcDNA6/myc-his-EGFP B may be useful as a genetic tool for mammalian cells and a vector for gene therapy.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prevalence and major risk factors of fatty liver among adult residents in Shanghai.</p><p><b>METHODS</b>A cross-sectional survey with multiple-stage stratified cluster and random sampling was performed. All residents aged 16 and above were invited to participate in the survey; they came from four communities of Yangpu District and Pudong New District. Questionnaire, physical examination, serum lipid-profile, and 75 gram oral glucose tolerance test and ultrasonographic examination of liver were undertaken. Analysis of data was performed through SPSS 11.0 for Windows statistical package.</p><p><b>RESULTS</b>A total of 3175 residents took part in the survey, which was 75% of adult residents of the investigated communities and 2.26/10 000 of Shanghai municipal residents. Of the 3175, 1218 were males and 1957 were females. The mean age of the participants was 52.4+/-15.1 years and ranged from 16 to 88 years. Fatty liver was detected with ultrasound examination in 661 participants (20.82%), among which 3.48% had alcoholic fatty liver, 4.08% had suspected alcoholic fatty liver, and 92.43% had nonalcoholic fatty liver. The age-adjusted, sex-adjusted prevalence of fatty liver in Shanghai adult residents was 17.29%, the prevalence of alcoholic fatty liver, suspicious alcoholic fatty liver, and nonalcoholic fatty liver in Shanghai adult residents were 0.79%, 1.15%, and 15.35%, respectively. The prevalence of fatty liver was increased with aging in males and in females. Among participants younger than 50 years old, the prevalence of fatty liver in males was significantly higher than that in females, but in participants older than 50 years the case was just the opposite, higher in females. The mean age (years), body mass index (BMI), waist circumference, blood pressure, fasting and two hour serum glucose level, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and the presence of obesity, diabetes mellitus, hypertension, dyslipidemia, and gallstones in the fatty liver group was significantly higher than those in the group without fatty liver, but the high-density lipoprotein cholesterol (HDL-C) level and the educational level were both lower in the fatty liver group. Logistic regression analysis demonstrated that the prevalence of fatty liver was only positively correlated to nine risk factors, including male sex, educational level, waist circumference, BMI, fasting glucose level, HDL-C, TG, hypertension and diabetes mellitus. In heavy drinkers, obesity increased the risk for fatty liver by 4.8-fold, but heavy drinking only increased the risk for fatty liver 1.5-fold (95% CI 0.9-2.6, P=0.1685).</p><p><b>CONCLUSION</b>There is a high prevalence of fatty liver among adult residents in Shanghai, and nonalcoholic fatty liver is the major type. Metabolic disorders such as obesity and diabetes mellitus, hypertension and hyperlipidemia are more closely associated with fatty liver than heavy drinking in Shanghai.</p>
