Hepatoid adenocarcinoma of the stomach (HAS) is defined as a special type of gastric cancer characterized by low incidence rates and high degree of malignance with an extremely poor prognosis.As it is characterized by morphological similarities to general alimentary cannal symptoms with unclear etiology and pathogenesis,diagnostic errors can always be made.The alpha-fetoprotein (AFP) and carcino-embryonic antigen (CEA) are helpful with diagnosis.However,histopathological examination is the gold standard for diagnosing HAS.So far,radical operation,adjuvant chemotherapy,interventional therapy with immune-biological treatment are the main approaches for HAS treatment.

The Z-drugs (zolpidem, zopiclone, and zaleplon), as the innovative hypnotics, have an improvement over the traditional benzodiazepines in the management of insomnia. Z-drugs have significant hypnotic effects by reducing sleep latency and improving sleep quality, though duration of sleep may not be significantly increased. As benzodiazepines, Z-drugs exert their effects through increasing the transmission of γ-aminobutyric acid. Z-drugs overdose are less likely to be fatal, more likely would result in poisoning. Z-drugs can be detected in blood, urine, saliva, and other postmortem specimens through liquid chromatography-mass spectrometry techniques. Zolpidem and zaleplon exhibit significant postmortem redistribution. Z-drugs have improved pharmacokinetic profiles, but incidence of neuropsychiatric sequelae, poisoning, and death may prove to be similar to the other hypnotics. This review focuses on the pharmacology and toxicology of Z-drugs with respect to their adverse effect profile and toxicity and toxicology data in the field of forensic medicine.

Since Nature published the first report in 2002 on using immunodeficient mice as recipients and allogeneous or heterogeneous testes as donor tissues to study the ectopic development of spermatogenic cells, the technique has been widely applied in various species (including human). In comparison with other in vitro maturation methods for male germ cells, testicular allografting or xenografting technique has such advantages as similar environment for the development of germ cells in physiological conditions, and better reproducibility. Up to now, sperm has been successfully produced by this technique from the testicular tisues of the immature mouse, hamster, cat, rabbit, pig, goat, bovine and rhesus monkey, and their offspring have even been generated by ICSI technique using the mouse and rabbit sperm derived from testis grafts. This article comprehensively reviews the development of the technique by discussing the influencing factors on the germ cell development in grafts including the variety and age of donors, the sex, integrity and immunity of recipients, the graft location and grafting time. And the applications of the technique and the existing problems are discussed as well.

BACKGROUNDBeta-catenin, a 92 kDa protein that binds to the cytoplasmic tail of E-cadherin, has an essential role in intercellular adhesion and signal transduction. Aberrant expression of beta-catenin has been associated with progression and metastasis of various human cancers. The aim of this study was to elucidate the expression pattern of beta-catenin in primary oral squamous cell carcinoma and examine the correlation between beta-catenin expression and tumor differentiation, histological grade and lymph node status as well as its clinical significances.
METHODSSeventy-six patients with oral squamous cell carcinoma and sixteen metastatic lymph nodes were studied. The beta-catenin expression was determined by immunohistochemical staining. The correlation with clinical, histological data was analyzed statistically.
RESULTSNormal oral epithelium showed strong beta-catenin expression at the cell membrane, but no cytoplasmic or nuclear expression. Different degrees of reduced expression of beta-catenin at the cell membrane were found in 54 cases with squamous cell carcinoma (71%). Cytoplasmic beta-catenin expression was found in 17 tumors (22.4%). Three cases were found with nuclear beta-catenin expression. In sixteen lymph nodes with metastatic squamous cell carcinoma, negative beta-catenin expression at the cell membrane was seen in 13 tumors (81.2%) and weak expression in 3 tumors (18.8%). Statistical analysis showed that there was an inverse correlation between beta-catenin expression and lymph node status and histological grade of tumors.
CONCLUSIONSReduced beta-catenin expression at the cell membrane is clearly associated with lymph node metastasis. A reduced expression of beta-catenin may constitute a hallmark of aggressive biological behavior of squamous cell carcinoma.
