Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The liver toxicity of Reynoutria multiflora (Thunb.) Moldenke. (Polygonaceae) (Polygonum multiflorum Thunb, PM) has always attracted much attention, but the related toxicity materials and mechanisms have not been elucidated due to multi-component and multi-target characteristics. In previous hepatotoxicity screening, different components of PM were first evaluated and the hepatotoxicity of component D [95% ethanol (EtOH) elution] in a 70% EtOH extract of PM (PM-D) showed the highest hepatotoxicity. Furthermore, the main components of PM-D were identified and their hepatotoxicity was evaluated based on a zebrafish embryo model. However, the hepatotoxicity mechanism of PM-D is unknown. AIM OF THE STUDY This work is to explore the hepatotoxicity mechanisms of PM-D by integrating network toxicology and spatially resolved metabolomics strategy. MATERIALS AND METHODS A hepatotoxicity interaction network of PM-D was constructed based on toxicity target prediction for eight key toxic ingredients and a hepatotoxicity target collection. Then the key signaling pathways were enriched, and molecular docking verification was implemented to evaluate the ability of toxic ingredients to bind to the core targets. The pathological changes of liver tissues and serum biochemical assays of mice were used to evaluate the liver injury effect of mice with oral administration of PM-D. Furthermore, spatially resolved metabolomics was used to visualize significant differences in metabolic profiles in mice after drug administration, to screen hepatotoxicity-related biomarkers and analyze metabolic pathways. RESULTS The contents of four key toxic compounds in PM-D were detected. Network toxicology identified 30 potential targets of liver toxicity of PM-D. GO and KEGG enrichment analyses indicated that the hepatotoxicity of PM-D involved multiple biological activities, including cellular response to endogenous stimulus, organonitrogen compound metabolic process, regulation of the apoptotic process, regulation of kinase, regulation of reactive oxygen species metabolic process and signaling pathways including PI3K-Akt, AMPK, MAPK, mTOR, Ras and HIF-1. The molecular docking confirmed the high binding activity of 8 key toxic ingredients with 10 core targets, including mTOR, PIK3CA, AKT1, and EGFR. The high distribution of metabolites of PM-D in the liver of administrated mice was recognized by mass spectrometry imaging. Spatially resolved metabolomics results revealed significant changes in metabolic profiles after PM-D administration, and metabolites such as taurine, taurocholic acid, adenosine, and acyl-carnitines were associated with PM-D-induced liver injury. Enrichment analyses of metabolic pathways revealed tht linolenic acid and linoleic acid metabolism, carnitine synthesis, oxidation of branched-chain fatty acids, and six other metabolic pathways were significantly changed. Comprehensive analysis revealed that the hepatotoxicity caused by PM-D was closely related to cholestasis, mitochondrial damage, oxidative stress and energy metabolism, and lipid metabolism disorders. CONCLUSIONS In this study, the hepatotoxicity mechanisms of PM-D were comprehensively identified through an integrated spatially resolved metabolomics and network toxicology strategy, providing a theoretical foundation for the toxicity mechanisms of PM and its safe clinical application.

Abstract
OBJECTIVE To investigate the protective effect of Echinococcus granulosus hydatid cyst fluid protein (HCFP) on ovalbumin (OVA)-induced allergic rhinitis (AR) in mice. METHODS Twenty-four BALB/c mice at ages of 8 to 10 weeks, each weighing approximately 20 g, were randomly divided into four groups, including groups A (blank control group), B (blank intervention group), C (AR model group) and D (AR+HCFP intervention group), with 6 mice in each group. On days 0, 2, 4, 6, 8, 10 and 12, mice in groups A, B, C and D were injected with 200 μL sterile phosphate buffered saline (PBS), 200 μL sterile PBS containing 20 μg HCFP, 200 μL sterile PBS containing 50 μg OVA and 5 mg Al(OH)3 gel, and 200 μL sterile PBS containing 50 μg OVA, 5 mg Al(OH)3 gel and 20 μg HCFP, respectively. On days 14 to 20, mice in groups A, B, C and D were administered with 40 μL sterile PBS, 40 μL sterile PBS containing 20 μg HCFP, 40 μL sterile PBS containing 2 mg OVA and 40 μL sterile PBS containing 2 mg OVA and 20 μL HCFP by nasal drop, respectively. Mouse behavioral changes were observed and behavioral scores were estimated. The serum levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), IL-5, IL-10, transforming growth factor-β (TGF-β) and OVA-specific IgE antibody (OVA-sIgE) were measured using enzyme-linked immunosorbent assay (ELISA), and the pathological changes of mouse nasal mucosa were observed by hematoxylin and eosin (HE) staining. RESULTS The mean behavioral score was significantly greater in Group C (6.83 ± 0.50) than in groups A (1.17 ± 0.52) and B (1.33 ± 0.52) (P < 0.05), while a lower mean behavioral score was estimated in Group D (3.50 ± 0.50) than in Group C (P < 0.05). There were significant differences among the groups in terms of serum IFN-γ (F = 4.08, P < 0.05), IL-4 (F = 275.90, P < 0.05), IL-5 (F = 96.82, P < 0.05), IL-10 (F = 77.67, P < 0.05), TGF-β (F = 9.98, P < 0.05) and OVA-sIgE levels (F = 44.69, P < 0.05). The serum IFN-γ level was significantly lower in Group C than in groups A, B and C (P < 0.05), and the serum levels of IL-4, IL-5 and OVA-sIgE were significantly higher in Group C than in groups A, B and C (P < 0.05), while the serum IL-10 and TGF-β levels were significantly greater in Group D than in Group C (P < 0.05). Microscopy showed apparent loss of nasal mucosa cilia, increased number and enlargement of goblet cells, interstitial edema and submucous vascular dilation in Group C, while the pathological changes of nasal mucosa were alleviated in Group D relative to Group C. CONCLUSIONS E. granulosus HCFP has a protective activity against OVA-induced allergic rhinitis in mice.

Abstract
OBJECTIVE To analyze the components of proteins from Echinococcus granulosus cyst fluid using the shotgun method, and to identify the active components with potential regulatory effects for immune dysregulation diseases. METHODS The E. granulosus cyst fluid was collected aseptically from the hepatic cysts of patients with cystic echinococcosis, and characterized by liquid chromatography (LC) tandem mass spectrometry (MS/MS) following digestion with trypsin. The protein data were searched using the software MaxQuant version 1.6.1.0 and the cellular components, molecular functions, and biological processes of the identified proteins were analyzed using the Gene Ontology (GO) method. RESULTS The E. granulosus cyst fluid separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) had a relative molecular mass of 25 to 70 kDa. LS-MS/MS analysis identified 37 proteins, including 32 known proteins and 5 unknown proteins. At least 4 proteins were preliminarily found to exhibit potential regulatory effects for immune dysregulation diseases, including antigen B, glutathione-S-transferase (GST), thioredoxin peroxidase (TPX) and malate dehydrogenase (MDH). GO enrichment analysis showed that the identified proteins had 149 molecular functions and were involved in 341 biological processes. CONCLUSIONS E. granulosus cyst fluid has a variety of protein components, and four known proteins are preliminarily identified to be associated with immune dysregulation diseases.

Abstract
BACKGROUND The raw and processed roots of Polygonum multiflorum Thunb (PM) are commonly used in clinical practice to treat diverse diseases; however, reports of hepatotoxicity induced by Polygoni Multiflori Radix (PMR) and Polygoni Multiflori Radix Praeparata (PMRP) have emerged worldwide. Thus, it is necessary for researchers to explore methods to improve quality standards to ensure their quality and treatment effects. METHODS In the present study, an ultra-high performance liquid chromatography triple quadrupole mass spectrometry (UHPLC-QQQ-MS/MS) method was optimized and validated for the determination of dianthrones in PMR and PMRP using bianthronyl as the internal standard. Chromatographic separation with a gradient mobile phase [A: acetonitrile and B: water containing 0.1% formic acid (v/v)] at a flow rate of 0.25 mL/min was achieved on an Agilent ZORBAX SB-C18 column (2.1 mm × 50 mm, 1.8 μm). The triple quadrupole mass spectrometer (TQMS) was operated in negative ionization mode with multiple reaction monitoring for the quantitative analysis of six dianthrones. Moreover, compounds 5 and 6 were further evaluated for their cytotoxicity in HepaRG cells by CCK-8 assay. RESULTS The UHPLC-QQQ-MS/MS method was first developed to simultaneously determine six dianthrones in PMR and PMRP, namely, polygonumnolides C1-C4 (1-4), trans-emodin dianthrones (5), and cis-emodin dianthrones (6). The contents of 1-6 in 90 batches of PMR were in the ranges of 0.027-19.04, 0.022-13.86, 0.073-15.53, 0.034-23.35, 0.38-83.67 and 0.29-67.00 µg/g, respectively. The contents of 1-6 in 86 batches of commercial PMRP were in the ranges of 0.020-13.03, 0.051-8.94, 0.022-7.23, 0.030-12.75, 0.098-28.54 and 0.14-27.79 µg/g, respectively. Compounds 1-4 were almost completely eliminated after reasonable processing for 24 h and the contents of compounds 5 and 6 significantly decreased. Additionally, compounds 5 and 6 showed inhibitory activity in HepaRG cells with IC50 values of 10.98 and 15.45 μM, respectively. Furthermore, a systematic five-step strategy to standardize TCMs with endogenous toxicity was proposed for the first time, which involved the establishment of determination methods, the identification of potentially toxic markers, the standardization of processing methods, the development of limit standards and a risk-benefit assessment. CONCLUSION The results of the cytotoxicity evaluation of the dianthrones indicated that trans-emodin dianthrones (5) and cis-emodin dianthrones (6) could be selected as toxic markers of PMRP. Taking PMR and PMRP as examples, we hope this study provides insight into the standardization and internationalization of endogenous toxic TCMs, with the main purpose of improving public health by scientifically using TCMs to treat diverse complex diseases in the future.

Abstract
BACKGROUND The roots of Polygonum multiflorum (PM) are a well-known traditional Chinese medicine, widely used to treat a variety of conditions in Southeast Asia, South Korea, Japan and other countries. It is known that Polygoni Multiflori Radix Praeparata (PMRP) may enhance the efficacy and reduce the toxicity of PM. However, reports of adverse reactions, such as hepatotoxicity, caused by PM or PMRP, have continuously appeared around the world, which increased the known risks of the medication and gradually gained the extensive attention of many researchers. The chemical constituents of PM that cause hepatotoxicity have not been distinctly elucidated using the traditional phytochemical screening. Recently, with the rapid development of metabolomics, there has been a growing need to explore the potential hepatotoxic components and mechanisms of PM. METHODS The metabolites and metabolomics of PM were searched by the Web of Science, PubMed, Google scholar and some Chinese literature databases. RESULTS A brief description of metabolites and metabolomics of PM is followed by a discussion on the metabolite- induced toxicity in this review. More than 100 metabolites were tentatively identified and this will contribute to further understanding of the potential hepatotoxic components of PM. Meanwhile, some toxic compounds were identified and could be used as potential toxic markers of PM. CONCLUSION This review mainly outlines the metabolites and metabolomics of PM that have been identified in recent years. This study could help to clarify the potential hepatotoxic components and metabolic mechanisms of PM and provide a scientific reference for its safe clinical use in the future.

Abstract
Trichinellosis is a worldwide zoonotic parasitic disease, which may infect humans and a wide range of animals, including carnivores, herbivores and even birds. Humans get infections through ingestion of raw or semi-cooked meat or meat products containing live Trichinella larvae. Currently, this zoonosis is predominantly prevalent in southwestern, northeastern and central parts of China, which poses a great threat to human health and socioeconomic development. In addition, the emergent public health hazards caused by trichinellosis outbreaks greatly threaten human health and social stability. This review describes the current status, diagnosis, treatment and control measures of trichinellosis in China, so as to provide insights into trichinellosis control in the country.

Abstract
Abstract Traditional species identification has gone through five stages -- morphology, cytology, biochemistry, immunology and molecular biology. At present, the use of DNA technology for species identification has become a research hotspot. In the use of DNA for species identification, the presentation and application of DNA barcode is of epoch-making significance. With the successful application of new technology in species identification, forensic species identification has also made corresponding development, and is expected to play an important role in forensic related fields. This paper briefly describes the general situation and principles of DNA barcode technology as well as its advantages and limitations when applied to biological classification, and discusses the future significance and feasibility of DNA barcode technology in forensic applications, in order to provide new ideas for future forensic identification.

Abstract
Polygonum multiflorum Thunb. (PM) is a traditional Chinese medicine, commonly used to treat a variety of diseases. However, the hepatotoxicity associated with PM hampers its clinical application and development. In this study, we refined the zebrafish hepatotoxicity model with regard to the following endpoints: liver size, liver gray value, and the area of yolk sac. The levels of alanine aminotransferase, aspartate transaminase, albumin, and microRNAs-122 were evaluated to verify the model. Subsequently, this model was used to screen different extracts, components, and constituents of PM, including 70 % EtOH extracts of PM, four fractions from macroporous resin (components A, B, C, and D), and 19 compounds from component D. We found that emodin, chrysophanol, emodin-8-O-β-D-glucopyranoside, (cis)-emodin-emodin dianthrones, and (trans)-emodin-emodin dianthrones showed higher hepatotoxicity compared to other components in PM, whereas polyphenols showed lower hepatotoxicity. To the best of our knowledge, this study is the first to identify that dianthrones may account for the hepatotoxicity of PM. We believe that these findings will be helpful in regulating the hepatotoxicity of PM.

Abstract
A phytochemical study on a 70% EtOH extract of dried roots of Polygonum multiflorum resulted in the isolation of four undescribed stilbene glucosides, namely multiflorumisides HK (1-4). The structures of the natural products were elucidated by 1D and 2D nuclear magnetic resonance (NMR) as well as mass spectroscopy analyses. Among them, multiflorumiside J (3) and multiflorumiside K (4) belong to rare tetramer stilbene glucosides. Moreover, the in vitro inhibitory activities against protein tyrosine phosphatase 1B (PTP1B) were evaluated and the putative biosynthetic pathway was proposed. Notably, compounds 1-4 showed the inhibitory activity against PTP1B with the IC50 values of 1.2, 1.7, 1.5 and 4.6 μm, respectively. Based on the obtained results, stilbene glucosides could be the potential PTP1B inhibitors of P. multiflorum.

Abstract
Objective: To investigate the systemic expression profile of S100A8 and S100A9 in healthy and inflamed periodontal tissues. Methods: Experimental periodontitis models were established by ligations around the mandibular second molars of six beagle dogs for 12 weeks (ligation group). The mandibular second molars on the opposite side were kept clean (healthy control group). The expressions of S100A8 and S100A9 in healthy and inflamed periodontal tissues of six beagle dogs were examined by immunohistochemistry. The expressions of S100A8 and S100A9 in primary human gingival fibroblasts (hGF) from 3 subjects and human periodontal ligament cells (hPDLC) from 3 other subjects were detected by immunocytochemistry. Results: After the ligation for 12 weeks, the mean probing depth of ligation group [(3.86±0.14) mm] was significantly higher than that of healthy control group [(2.11±0.28) mm] (P<0.01). Results of immunohistochemistry analysis indicated that S100A8 and S100A9 could be expressed in gingival epithelial cells and might infiltrated neutrophils in the healthy periodontium. Except for the gingival epithelial cells and neutrophils, both proteins were induced and expressed in gingival fibroblasts, periodontal ligament cells, microvascular endothelial cells and bone marrow fibroblasts under inflammatory conditions. The distribution of S100A8 and S100A9 differed in the healthy oral gingival epithelium (OGE), which becomes consistent in inflamed OGE. Additionally, the expressions of S100A8 and S100A9 were confirmed in primary hGF and hPDLC. Conclusions: Periodontal inflammation might enlarge the expression scope of S100A8 and S100A9 and enrich multiple cells with expressions of S100A8 and S100A9.

Abstract
Objective: To study the changes of gonadotropin releasing hormone agonist (GnRH-a) in pinopodes during luteal phase and to explore the possible mechanism of GnRH-a in luteal phase support of assisted reproductive technology (ART). Methods: Totally 40 primary infertility women who were treated with ART due to male factors were enrolled, according to the order of the group they were randomly divided into experimental group and control group. On the 7th day after ovulation, the experimental group received a subcutaneous injection of 0.1 mg of GnRH-a, while the control group received a subcutaneous injection of placebo only (0.9% saline 2 ml), 3 days later they came to the clinic again. Serum estradiol and progesterone levels were measured before and after treatment in each group. Pinopodes were collected for electron microscopic examination. Levels of ER and PR were detected by western blot. Results: (1) There was no significant difference between the experimental group and the control group in the estrogen level before and after the treatment (all P>0.05). The level of progesterone in the experimental group after treatment [(66.8±14.9) nmol/L] was significantly higher than that before treatment(P<0.05); also significantly higher than the same period of the control group (P<0.05). (2) There was no significant difference in the expression of ER protein in the experimental group before and after treatment (P>0.05). The expression of PR in the experimental group after treatment was significantly lower than that before treatment (P<0.05); also lower than the same period of the control group (P<0.05). (3) Expression amount of pinopodes in the experimental group after treatment was significantly higher than that before treatment [65% (13/20) versus 25% (5/20), P<0.05], and the development trend was more mature [the percentage of maturation:75% (15/20) versus 35% (7/20), P<0.05]. Expression amount of pinopodes after treatment and the percentage of maturation in the experimental group were significantly higher than those in the same period of control group (P<0.05). Conclusion: GnRH-a in luteal phase support may play a role through the corpus luteum, which may promote the secretion of progesterone, downregulation of PR expression, promote the growth of pinopodes, and improve the endometrial receptivity.

Abstract
Diabetic peripheral neuropathy (DPN), a common complication of diabetes, has a high morbidity, and currently there is no effective therapy. To investigate the clinical effect of traditional Chinese medicine in combination with Western medicine, 88 patients with early DPN who were admitted to Binzhou City Center Hospital, Shandong, China, between November 2015 and November 2016, were selected as the research subjects and were randomly divided into a control group and an observation. Patients in the control group were treated by conventional Western medicine, while patients in the observation group were treated by traditional Chinese medicine in addition to conventional Western medicine. The clinical effect was compared between the two groups. The results demonstrated that the overall effective rate of the observation group was much higher than that of the control group, and the difference was statistically significant (P less than 0.05). The vibration perception threshold (VPT) of nervus peroneus communis, nervus suralis and posterior tibial nerve of the two groups significantly declined after treatment (P less than 0.05), however, the decreae in the observation group was more obvious (P less than 0.05). The improvement of glycosylated hemoglobin (HbAlc) and blood glucose of the observation group was superior to that of the control group, and the difference had statistical significance (P less than 0.05). In conclusion, traditional Chinese medicine in combination with Western medicine has a remarkable effect in the treatment of DPN and can effectively relieve vital signs and clinical symptoms of patients and significantly improve nerve conduction velocity. The therapy is worth clinical application and promotion.

Abstract
Two combination chemotherapy protocols, CMF (cyclophosphamide, methotrexate, fluorouracil) and CMFH (CMF plus homoharringtonine), were tested in advanced breast cancer patients. The response rate of CMF was 50% in 44 cases, and that of CMFH was 54.16% in 48 cases; the difference was not significant. There was also no difference between the median duration of response and the median survival of the two protocols. It was concluded that the addition of homoharringtonine to the CMF protocol gave no additional benefit.

Abstract
We evaluated the application of three machine learning algorithms, including logistic regression, support vector machine and back-propagation neural network, for diagnosing congenital heart disease and colorectal cancer. By inspecting related serum tumor marker levels in colorectal cancer patients and healthy subjects, early diagnosis models for colorectal cancer were built using three machine learning algorithms to assess their corresponding diagnostic values. Except for serum alpha-fetoprotein, the levels of 11 other serum markers of patients in the colorectal cancer group were higher than those in the benign colorectal cancer group (P < 0.05). The results of logistic regression analysis indicted that individual detection of serum carcinoembryonic antigens, CA199, CA242, CA125, and CA153 and their combined detection was effective for diagnosing colorectal cancer. Combined detection had a better diagnostic effect with a sensitivity of 94.2% and specificity of 97.7%; combining serum carcinoembryonic antigens, CA199, CA242, CA125, and CA153, with the support vector machine diagnosis model and back-propagation, a neural network diagnosis model was built with diagnostic accuracies of 82 and 75%, sensitivities of 85 and 80%, and specificities of 80 and 70%, respectively. Colorectal cancer diagnosis models based on the three machine learning algorithms showed high diagnostic value and can help obtain evidence for the early diagnosis of colorectal cancer.

Abstract
BACKGROUND CA19-9, CA125, AFP, CEA, and CA153 are common cancer biomarkers. This study aimed to detect the expression and assess clinical significance of these biomarkers in ovarian mature cystic teratomas (OMCT). MATERIALS AND METHODS The clinical data of 312 resected patients with ovarian mature cystic teratoma referred to the third Hospital of Suzhou University from January 2008 to February 2014 were analyzed retrospectively. Levels of serum CA19-9, CA125, CA153, AFP, and CEA were detected. RESULTS Levels of serum CA19-9, CA125, AFP, and CEA were detected in all patients, but the level of serum CA153 was detected in 36 patients. The positive expression of these biomarkers above is 45.83%, 6.09%, 0.00%, 0.64%, and 2.78%, respectively. Ovarian tumor diameter in CA19-9 and CA 125 elevation is larger than that in negative group. The levels of serum CA19-9 and CA125 in multilocular ovarian tumor patients is higher than that in unilocular ovarian tumor patients. The level of serum CA19-9 in bilateral ovarian tumor patients is higher than that in unilateral patients. The level of CA19-9 in patients three months after operation decreased significantly compared with that before operation. CONCLUSIONS The present study suggests that elevated CA 19-9 is probably the most reliable marker among many tumor markers in the OMCT. It is valuable for diagnosis and recurrence of OMCT.

Abstract
Gossypium tomentosum is a wild allotetraploid species with the (AD)5 genome. It is characterized by many useful traits including finer fiber fineness, drought tolerance, and Fusarium and Verticillium resistance. We constructed the first bacterial artificial chromosome library for Gossypium tomentosum. With high quality and broad coverage, this library includes 200,832 clones, with an average insert size of about 122 kb and fewer than 3% empty clones. Our library is approximately 10-fold the size of the (AD)5-genome (2400 Mb) and provides a 99.7% probability of isolating genes of interest or their sequences. Seven of eight simple sequence repeats markers that are located on five different chromosomes and linked with resistance to Verticillium wilt could amplify the 50 superpools and obtained one to five hits. This high capacity library will be an important genomic resource for classifying and analyzing the evolution of allotetraploid cotton species as well as for isolating disease-resistance and drought-tolerance genes.

Abstract
We studied the immunomodulatory and clinical effects of the empirical formula "tiaomian III decoction" on maternal blood blocking antibody deficiency and recurrent spontaneous abortion. Sixty-one patients with blocking antibody deficiency were divided in the experimental group (N = 31), who took tiaomian III decoction, and the control group (N = 30), who received active immunotherapy with paternal lymphocytes; both treatments lasted 3 months. Blocking antibodies, anti-idiotypic antibodies, interleukin, T-lymphocyte subsets, and macrophage colony-stimulating factor (M-CSF) were tested. After treatment, the positive conversion rate reached 87.1 and 86.7% in the experimental and control groups, respectively. After treatment, CD4 levels decreased while CD8 levels increased in both groups. The CD4/CD8 ratio was higher than normal and increased significantly from pre-treatment (P < 0.05). IL-10 and M-CSF levels increased significantly in both groups (P < 0.05). The 1-year conception rates of the experimental and control groups were 58.1 and 46.7%, respectively (P < 0.05). The results show the tiaomian III decoction can increase the positive conversion rate of maternal blocking antibodies and promote the production of IL-10 and M-CSF. Thus, it strengthens the maternal body's protection of the fetus and maintenance of conception. The higher conception rate of the experimental group demonstrates the positive clinic efficacy of the tiaomian III decoction on maternal blood blocking antibody deficiency and recurrent spontaneous abortion.

Abstract
We describe a reliable fabrication procedure of silver tips for scanning tunneling microscope (STM) induced luminescence experiments. The tip was first etched electrochemically to yield a sharp cone shape using selected electrolyte solutions and then sputter cleaned in ultrahigh vacuum to remove surface oxidation. The tip status, in particular the tip induced plasmon mode and its emission intensity, can be further tuned through field emission and voltage pulse. The quality of silver tips thus fabricated not only offers atomically resolved STM imaging, but more importantly, also allows us to perform challenging "color" photon mapping with emission spectra taken at each pixel simultaneously during the STM scan under relatively small tunnel currents and relatively short exposure time.

Abstract
The antifatigue effects of the hot-water extract of longan (Dimocarpus longan Lour.) seeds were studied in mice. Longan seed polysaccharides were administered at doses of 50, 100, 200 and 400 mg/kg and antifatigue activity was evaluated using a swimming test, along with the determination of serum urea nitrogen, hepatic glycogen and blood lactic acid content. The results show that longan seed polysaccharides, in doses ranging from 50 to 100 mg/kg, extended swimming time, increased hepatic glycogen (p < 0.01, n = 10), reduced blood urea nitrogen (p < 0.01, n = 10) and decreased blood lactic acid (p < 0.01, n = 10) in the mice. Therefore longan seed polysaccharides may have potential as an antifatigue agent.

Abstract
The study was done in healthy volunteers to investigate the vasoconstrictor activity of three commercially available formulations of fluocinolone acetonide (Synalar gel, cream and ointment) and to determine whether they were bioequivalent. The influence of dilution of the cream formulation on activity was also examined. Twenty mg of each topical formulation was applied, followed by occlusion for 6 h, and the potency was evaluated by measuring the vasoconstrictor effect using tristimulus colour analysis. The cream formulation was more potent than the ointment, with the gel having intermediate strength. Dilution did not significantly reduce activity. While choice of an appropriate topical corticosteroid formulation largely depends on the nature of the lesions, this study has shown that different formulations of nominally the same concentration have different potencies; dilution up to 1 in 10 produced no significant reduction in potency. The potency classification in the British National Formulary for formulations of Synalar may need revision.

Abstract
Oligodeoxynucleotides (Oligomers) including modified and unmodified, homo- and heterooligomers were tested for their ability to inhibit mouse SRS leukemia virus (SRSV)-induced proliferation of cells, colony formation, syncytium formation and reverse transcriptase (RT) activity in vitro. Phosphorothioate analogs complementary to Mo-MuLV sequences, as well as noncomplementary homooligomers, were found to be active. Unmodified homooligomer (dC14) also showed inhibition of growth of ascitic lymphoma carrying SRS virus. Our study suggests that different classes of oligonucleotides may inhibit SRSV replication with different mechanisms.
