Producing qualified forensic pathological practitioners is a common difficulty around the world. In China, forensic pathology is one of the required major subspecialties for undergraduates majoring in forensic medicine, in contrast to forensic education in Western countries where forensic pathology is often optional. The enduring predicament is that the professional qualities and abilities of forensic students from different institutions vary due to the lack of an efficient forensic pedagogical model.

Typical cases used as teaching materials vividly represent intoxication and provide students with an opportunity to practice and hone resolving skills. In 2013, the Department of Forensic Pathology at Zhongshan School of Medicine began to construct top-quality courses in forensic toxicology, with its first step, creating a base containing typical cases of intoxication.

Methods And Results: In 8 of 120 SUNDS cases, we detected an East Asian common VCL variant p.
Increasing evidence observed in clinical phenotypes show that abrupt breathing disorders during sleep may play an important role in the pathogenesis of sudden unexplained nocturnal death syndrome (SUNDS). The reported Brugada syndrome causing mutation R1512W in cardiac sodium channel α subunit encoded gene SCN5A, without obvious loss of function of cardiac sodium channel in previous in vitro study, was identified as the first genetic cause of Chinese SUNDS by us. The R1512W carrier was a 38-year-old male SUNDS victim who died suddenly after tachypnea in nocturnal sleep without any structural heart disease.

Genomic DNA was extracted from blood samples of 127 SUNDS cases and 165 healthy unrelated controls. None of the published or novel RyR2 missense mutations were found in 127 SUNDS cases.

Previous studies have implicated that SUNDS is probably allelic to cardiac sodium channel diseases such as Brugada syndrome. The variation in cardiac potassium channels is the main genetic cause of inherited long QT syndrome (LQTS), which may manifest as syncope and sudden cardiac death without structural disease.

However, the success of free flaps in head and neck reconstruction depends on the presence and quality of the recipient vessels in the neck for microvascular anastomosis. The supraclavicular artery island flap can be used to reconstruct a variety of head and neck defects, allowing the reconstructive surgeons to circumvent some of the problems inherent in vessel-depleted necks.
