GAS7在人骨肉瘤中的表达及其意义

Objective： To detect the expression of GAS7 in osteosarcoma and discuss its significance. Methods： Immunohistochemistry SABC method was applied to detect GAS7 expression in specimens of 54 osteosarcoma and 15 osteochondroma cases. Results： The positive expression rate of GAS7 was 74.7% （40/54） in the group of osteosarcoma and 0% （0/15） in the group of osteochondroma. There was a significant difference in the comparison of GAS expression in these two groups （P 〈 0.05）. GAS7 was higher expressed in the samples which complicated with relapse or pulmonary metastasis than the control group （P 〈 0.05）. There was no significant association between GAS7 expression and the size of tumor, the gender or the age of the patients （P 〉 0.05）. Conclusion： The hyper-expression ot GAST may play an important role in the initiation and development of human osteosarcoma.

诈骗艾滋知多少

艾滋病病毒的致病机制很特殊,它一旦进入人体,寄生在T4淋巴细胞内最核心的部位,与细胞核的遗传物质DNA整合为一体,病毒随免疫细胞DNA复制而复制.因此,它成了在全球不可根治的一种"超级瘟疫".在世界各国,对防治艾滋病投入了巨大的人力、财力,众多医学专家们绞尽了脑汁,直至今天尚无有效疫苗可防,更无药物可根治,临床医生束手无策,只能做到一些对症治疗,减轻病人的痛苦,延缓病情,但无法挽救病人的生命,这是科学家公认的结论.

The medically important dematiaceous fungi and their identification

Dematiaceous fungi include a large group of organisms that are darkly pigmented (dark brown, olivaceous, or black). In most cases the pigment is melanin, and specifically, dihydroxynaphthalene melanin. The diseases produced include chromoblastomycosis, eumycotic mycetoma, and phaeohyphomycosis. Phaeohyphomycosis is a new classification for a diverse group of previously known entities grouped together on the basis of finding dematiaceous hyphal and/or yeast-like forms in tissue; tissue involvement may be superficial, cutaneous and corneal, subcutaneous, or systemic. Identification of these fungi is based mostly upon morphology. Important structures include annellides (Phaeoannellomyces, Exophiala), phialides (Phialophora, Wangiella), adelophialides (Phialemonium without collarettes, Lecythophora with collarettes), differentiation of conidiophores (Xylohypha versus Cladosporium) and conidial hilum, septation and germination (Bipolaris, Drechslera, Exserohilum). Useful laboratory tests include the 12% gelatin test (controversial), nitrate assimilation (W. dermatitidis is negative, most other species are positive), and determination of temperature maxima (especially 37 degrees C for E. jeanselmei, 40 degrees C for W. dermatitidis and B. spicifera, 42 degrees C for X. bantiana, and 45 degrees C for Dactylaria constricta var. gallopava and Scedosporium inflatum).     

Orale Langzeitbehandlung von Onychomykosen mit Ketoconazol

Zusammenfassung: An der Studie zur Wirksamkeit und Anwendungssicherheit von Ketoconazol nahmen 27 Männer im Alter von 20 bis 80 (Median: 57) Jahre, davon 18 mit Onychomykosen und 9 als KontroUen bei den Laborwertbestimmungen, teil. Während des ersten Behandlungsmonats erhielten je 9 Patienten 200 mg und 400 mg Ketoconazol täglich. Danach wurden beide Gruppen 6 Monate mit 200 mg/d weiterbehandelt. Die klinische Beurteilung sowie hämatologische, biochemische und Plasmaspiegeluntersu-chungen erfolgten mindestens monafich, mykologische Untersuchungen wurden vor Aufnahme und bei Beendigung der Therapie vorgenommen. Erne letzte klinische Unter-suchung erfolgte 1 Jahr nach Beginn der Studie. Nach 7 Monaten Behandlung wurden 23 von 30 Nägeln mit “gebessert” bis “stark gebessert” beurteilt, nach dem behandlungsfreien Intervall galt dies für 28 von 30 Nägeln. Die Plasmaspiegel waren mit 200 mg/d ausreichend und uber den Behandlungszeit-raum konstant. Dies spricht für gute orale Resorption und Abwesenheit von Enzyminduktion. Die Laborwerte zeigten im Vergleich zu den Kontrollen und den Werten vor Behandlung keine signifikanten Abweichungen, so daß myelo-, nephro- und hepatotoxische Wirkungen von 400 bzw. 200 mg/d ausgeschlossen werden können. Der Lipidhaushalt wurde nicht beeinfluat und es trat unter Therapie als Folge der Ketoconazolwirkung lediglich Lanosterin im Serum auf. Nach Beendigung der Therapie ging der Lanosteringehalt schnell zurück. Damit erweist sich Ketoconazol in den angewandten Dosen als ein gut verträgliches und zur Langzeitbehandlung von Onychomykosen geeignetes Antimykotikum. Summary: Twenty-seven males with a median age of 57 (range: 20 to 80) years took part in this study on the efficacy and safety of ketoconazole. Eighteen men suffered from onychomycosis; nine served as controls in the safety evaluation. During the first month of treatment, nine patients received 200 mg and the nine other 400 mg ketoconazole daily. Then the treatment was uniformly continued with 200 mg/d for 6 months. Clinical evaluation and haematological, biochemical and plasma level investigations were carried out at least at monthly intervals; mycological controls were performed at the start and end of therapy. A final clinical evaluation was carried out one year after the start of the study. After 7 months of treatment, moderate or definite clinical improvement was obtained in 23 out of 30 nails. After 5 more months without antimycotic treatment this was the case in 28 of 30 nails. Plasma levels obtained with 200 mg ketoconazole daily were adequate and constant during the entire treatment period. This indicates a good oral resorption as well as the absence of induction of hepatic enzymes. The laboratory values did not show significant deviations as compared with the controls or with the pretreatment values. This excludes myelo-, nephro- and hepatotoxic effects of 400 and 200 mg ketoconazole daily. The lipid metabolism was not influenced, the only difference was the occurrence of lanosterol in the serum, which is a result of the mechanism of action of ketoconazole. After the medication period the lanosterol levels subsided rapidly. In the applied doses ketoconazole is a well-tolerated and effective drug for the systemic long-term treatment of onychomycosis.     

Laboratory Techniques Alternative to In Vivo Experiments for Studying the Liberation, Penetration and Fungicidal Action of Topical Antimycotic Agents in the Skin, Including Ciclopiroxolamine

Summary: Short-term experiments on excised skin (human, pig) gave the following results: 1. In the tissue activity test with direct inoculation (D-TAT) commercial preparations of the non-azole antimycotics ciclopiroxolamine, tolnaftate and naftifine, produced higher inhibitory activity against Trichophyton mentagrophytes (standard strain) in various levels of the horny layer than were produced by the azole antimycotics econazole, miconazole, clotrimazole, oxiconazole and bifonazole. Fast drying solutions of antimycotics invariably gave higher inhibitory activities than creams. In the ultrafiltration tissue activity test (UFT- TAT) against Candida albicans (2 strains), antimycotic agents ranked in order of effectiveness as follows: ciclopiroxolamine – most of the azole antimycotics – bifonazole and naftifine. 2. In tests of fungicidal activity against T. mentagrophytes (2 strains) and Microsporum gypseum (1 strain) the first step was to inoculate the skin surface. After the horny layer had been penetrated by fungal mycelia, antimycotic agents of documented fungicidal potency, chiefly in the form of creams, were applied to the skin surface and left to act for up to 18 hours. The horny layer and epidermis were then scraped off and the concentration of viable fungi was determined. Ciclopiroxolamine cream and lotion produced by far the greatest diminution in viable fungi; creams containing oxiconazole and naftifine were moderately effective and those containing tioconazole and bifonazole produced a relatively small decrease in viable fungi. To avoid erroneous results it is important to homogenize and dilute the skin scrapings; if this is not done certain antimycotics will give misleadingly high fungal killing rates. At this early stage the scatter of results is still wide and minor differences in efficacy cannot as yet be detected with certainty. 3. From the results of various comparative tests it is evident that pig skin can be used as a substitute for human skin in the tests listed under 1. and 2. above. This discovery may make a valuable contribution towards limiting the need for experiments on living animals and trials on human beings. Zusammenfassung: In Kurzzeitversuchen an exzidierter Haut (Mensch, Schwein) wurde gefunden: 1. Im Gewebeaktivitätstest mit direkter Inokulation (D-GAT) wurde mit Handelspräparaten der Nichtazol-Antimykotika Ciclopiroxolamin, Tolnaftat und Naftifin in verschiedenen Hornschichtniveaus eine höhere Hemmaktivität gegenüber Trichophyton mentagrophytes (Standard-Stamm) erzielt als mit solchen der Azol-Antimykotika Econazol, Miconazol, Clotrimazol, Oxiconazol und Bifonazol. Rasch trocknende Lösungen von Antimykotika ergaben durchweg höhere Hemmaktivitäten als Cremes. Im Ultrafiltrations-Gewebeaktivitätstest (UFT-GAT) gegenüber Candida albicans (2 Stämme) ergab sich nach erzielter Wirksamkeit die Rangfolge Ciclopiroxolamine – Mehrzahl der Azolantimykotika – Bifonazol und Naftifin. 2. In Fungizidie-Testen gegenüber T. mentagrophytes (2 Stämme) und Microsporum gypseum (1 Stamm) wurde zunächst die Hautoberfläche inokuliert. Nach Durchdringung der Hornschicht mit Pilzmyzelien wirkten auf die Hautoberfläche bis zu 18 Stunden lang überwiegend Cremes von als fungizid publizierten Antimykotika ein. Während sich in abgeschabter Hornschicht und Epidermis der so bearbeiteten Hautoberflächen mit Ciclopiroxolamin-Creme und -Lotion die weitaus höchste Verminderung lebensfähiger Keime ergab, bewirkten Cremes mit Oxiconazol und Naftifin eine mittlere und solche mit Tioconazol und Bifonazol eine relativ niedrige Keimeliminierung. Zur Vermeidung von fehlerhaften Ergebuissen mußten Homogenisierung und Verdünnung der Hautschabsel erfolgen, anderenfalls bei mehreren Antimykotika eine zu hohe Keimabtötung vorgetäuscht worden wäre. Wegen der vorerst noch hohen Streuung der Ergebnisse können kleinere Wirksamkeitsunterschiede noch nicht sicher erfaßt werden. 3. Nach dem Ergebnis verschiedener Vergleichstests kann in den Testen zu 1. und 2. Schweinehaut als Ersatz für Haut vom Menschen dienen und dürfte damit wesentlich zur Einschränkung von Versuchen am lebenden Tier und von Prüfungen am Menschen beitragen.     

Oncogénétique et psycho-oncologie, une collaboration recommandée...

Résumé: La possibilité depuis 1994, de connaître la probabilité individuelle de développer certains cancers a permis de proposer de nouvelles modalités de prévention, de traitements et contribué au développement actuel de loncogénétique. Une meilleure connaissance des répercussions psychologiques tant pour les patients que pour les apparentés est désormais possible et limplication des psycho-oncologues dans ce cadre de la réalisation des tests prédictifs, recommandée. La mission de «messager» qui incombe au «cas-index» doit faire lobjet dune attention particulière. La complexité de linformation et la dimension paradoxale que peut avoir parfois la communication à propos des choix, rend difficile lévaluation de la qualité du consentement. La situation particulièrement délicate dune aide à la décision à légard de la chirurgie prophylactique, exige une collaboration étroite des généticiens et des psycho-oncologues.Les soins de support en oncologie     

The role of papillomaviruses in human cancers

This review comprehensively evaluates the influence of gene-gene, gene-environment and multiple interactions on the risk of colorectal cancer (CRC). Methods of studying these interactions and their limitations have been discussed herein. There is a need to develop biomarkers of exposure and of risk that are sensitive, specific, present in the pathway of the disease, and that have been clinically tested for routine use. The influence of inherited variation (polymorphism) in several genes has been discussed in this review; however, due to study limitations and confounders, it is difficult to conclude which ones are associated with the highest risk (either individually or in combination with environmental factors) to CRC. The majority of the sporadic cancer is believed to be due to modification of mutation risk by other genetic and/or environmental factors. Micronutrient deficiency may explain the association between low consumption of fruit/vegetables and CRC in human studies. Mitochondrial modulation by dietary factors influences the balance between cell renewal and death critical in colon mucosal homeostasis. Both genetic and epigenetic interactions are intricately dependent on each other, and collectively influence the process of colorectal tumorigenesis. The genetic and environmental interactions present a good prospect and a challenge for prevention strategies for CRC because they support the view that this highly prevalent cancer is preventable.     

Antifungal combination therapy in localized candidosis

A mouse model of localized candidosis in air-filled subcutaneous cysts imitating thrush has been developed. We have now tested various antifungal combinations in this animal model. Flucytosine (5-FC) + amphotericin B (Amph B) showed the highest efficacy, a clear additive or even synergistic effect was seen. The combination of 5-FC + imidazole or triazole derivative was less efficacious, an additive effect was rare. The combination of 5-FC + Amph B was also tested against Candida albicans strains showing various degrees of 5-FC-resistance. A significant reduction in 5-FC-resistant mutants was seen after the treatment with the combination.     

Efficiency of crude and purified fungal antigens in serodiagnosis to discriminate mycotic from other respiratory diseases

Mycotic immunodiagnosis was performed in 186 hospitalized patients with different respiratory diseases, mostly considered as tuberculosis and others with a doubtful diagnosis. Crude histoplasmin, coccidioidin, paracoccidioidin, blastomycin, candidin, aspergillin, and sporotrichin, as well as purified polysaccharide-protein complexes (PPC) of Histoplasma capsulatum, Coccidioides immitis, and Paracoccidioides brasiliensis were used as antigens. Immune tests used included skin test (ST), gel immunodiffusion (ID), counterimmunoelectrophoresis (CIE), complement fixation (CF), and ELISA. A possible association with candidosis was observed in 17% of patients with tuberculosis and diabetes; one presumptive paracoccidioidomycosis, one confirmed aspergillosis, and six cases of active histoplasmosis were determined. Candidin ST showed 29% of positive reactions with an increased frequency in patients between 31 and 55 years of age. CF test showed the highest positivity percentages with crude antigens, specially for Candida antigen (26.3%) and histoplasmin (18.2%). Cross reactions were evident with crude antigens but decreased when PPC's were used in ELISA.     

Les génériques en cancérologie: à molécule identique, médicaments identiques? Les biosimilaires, des super-génériques?

Résumé: Les biosimilaires vont bientôt voir leur apparition en Europe. Comment un laboratoire peut-il aborder le développement de son dossier dAMM? Quelles sont les bases légales et les recommandations officielles? Comment la similarité et/ou le caractère générique peuvent-ils être démontrés? Les règles sont-elles identiques à celles des produits chimiques conventionnels pour lesquels, notamment en cancérologie, il existe des médicaments génériques? Comment faire pour que la sécurité et lefficacité des médicaments biosimilaires soient assurées pour les patients?     

Isoconazole nitrate in the treatment of tropical dermatomycoses

Summary. A total of 54 patients with culturally proven tropical dermatomycoses, comprising 23 with various types of dermatophytoses, one with foot infection due to Trichosporon beigelii and one with foot infection due to Geotrichum candidum , two with candidoses of the groin and 27 with pityriasis versicolor, were included in a clinical trial of efficacy of 1% isoconazole cream (Travogen^R, Schering, Berlin, Germany). Five patients were not evaluable. A clinical and mycological cure was achieved in 29 cases in 3–4 weeks. In 15 (31%) of the remaining patients treatment was required for 5–6 weeks, while another three patients required treatment for 8 weeks. In two patients the disease proved to be resistant to treatment with the drug.
