我国警察健康权益的现状分析与对策

目前我国警察身体健康和心理健康方面存在的问题不容忽视,保护警察合法权益,需建立健全警察权益保障法律制度,建立专门的警察权益监督保障机构,建立非警务活动审批监督机构,设立警察权益保护基金等。     

肠道菌群多样性变性梯度凝胶电泳分析法的建立

采用珠磨法、冻融研磨法和酶法对粪便细菌进行裂解,提取粪便细菌DNA,并采用16SrRNAV3区引物(P3GCf、P2r)和V6V8区引物(U968GCf、L1401r)扩增细菌16SrRNA基因可变区,对变性梯度凝胶电泳(DGGE)方法用于肠道菌群多样性分析的各种条件进行了优化,建立了分析人和动物粪便菌群多样性的DGGE方法。2对引物的粪便DGGE结果都表明,珠磨法和冻融研磨法对细菌的裂解效果优于酶法;P3GCf、P2r引物的条带数明显多于U968GCf、L1401r引物;珠磨法PCRDGGE对普通拟杆菌、青春双歧杆菌和粪肠球菌的检测限分别为(6.4±0.1)×102、(6.1±0.7)×103和(7.2±0.2)×105个细菌,珠磨法对这3种细菌的检测限均低于酶法。结果表明,珠磨法和P3GCf、P2r引物更适宜用于粪便菌群多样性DGGE分析。     

多重RT-PCR快速检测鉴别新城疫病毒强毒株和弱毒疫苗株方法的建立

根据新城疫病毒(NDV)基因结构的特点及强、弱毒株融合基因裂解位点的序列差异设计了4条引物,建立了一种可以快速鉴别NDV强毒株和弱毒疫苗株的多重PCR方法。检测结果显示,强毒株可以扩增出442 bp的特异性片段和671 bp的通用片段,弱毒疫苗株可以扩增出252bp的特异性片段和671 bp的通用片段。该方法只需进行一次RT-PCR,整个过程可在数小时内完成。经敏感性测定,该方法最低能检测到100 pg的NDV RNA。

损伤伴心血管系统疾病死亡42例法医病理学研究

目的探讨心血管系统疾病伴外伤死亡案例法医病理学特点,并从伤病的角度揭示两者之间的联系。方法42例心血管系统疾病伴损伤死亡案例均接受系统病理学解剖和组织学观察,且死因明确。结果42例中40岁以上者占到64.28%,男性较女性死者多。擦伤和挫伤在损伤中比例最大共占到80.95%,冠心病和高血压病死亡者各占45.24%、16.67%。损伤和疾病共存死亡案例共20例。结论在死因分析中年龄、性别、损伤类型、疾病分布有其规律性,死者中年龄偏老年化,损伤多为钝器、摔跌所致擦伤、挫伤。疾病中冠心病、高血压为最多。损伤和疾病对死因共同起作用的案例主。     

A Case of Sudden Infant Death Due to Incomplete Kawasaki Disease

Although Kawasaki disease (KD) is a self‐limiting disease, it may cause sudden cardiac death. Diagnosis of KD is principally based on clinical signs; however, some infant cases do not meet the criteria. Such cases are identified as incomplete KD. The sudden death risk in incomplete KD cases is similar to conventional KD. In our 5‐month‐old case, he had been admitted to a hospital for a fever and suppuration at the site of Bacille de Calmette et Guerin (BCG) vaccination. However, after discharge from the hospital, his C‐reactive protein (CRP) levels declined, he got indisposed and died suddenly. A medico‐legal autopsy revealed myocarditis, coronaritis, platelet‐aggregated emboli in coronary arteries, and myocardial degeneration, suggesting that the fatal myocardial infarction was due to thrombus emboli in the coronary arteries. Forensic pathologists therefore should pay attention to the cardiac pathology originated from incomplete KD as a potential cause in cases of sudden infant death.     

Commode Cardia—Death by Valsalva Maneuver: A Case Series

The Valsalva maneuver is used in clinical medicine for the diagnosis and/or treatment of various cardiovascular conditions. It can also be used in activities of daily living, such as defecation. Due to the cardiovascular effects produced during the Valsalva maneuver, it may be contraindicated in certain medical conditions and could be a trigger of sudden cardiac death. The incidence and prevalence of death following Valsalva maneuver in the presence of underlying cardiovascular disease, or “commode cardia,” has not been examined. In 2012, the Wayne County Medical Examiner's Office (Detroit, MI) investigated 21 deaths that occurred on the toilet, fourteen of which were due to cardiovascular disease. In another 31 deaths in the bathroom due to cardiovascular disease, the possibility that the decedent defecated immediately prior to death could not be excluded. Hence, the incidence of commode cardia in this population ranges from 2.3 to 7.4% of all cardiovascular‐related deaths.     

A Review of the Forensic Implications of Pica

Pica is characterized by the persistent eating of non‐nutritive substances over some time that is inappropriate for the maturation stage of the individual and is not culturally sanctioned. A 9‐year‐old boy with Goldenhar syndrome, significant developmental delay and pica, collapsed and died after a short history of diarrhea and vomiting. Death was due to a sigmoid volvulus resulting from filling of the distal colon with feces containing dirt, stones, and rice with evidence of ischemic intestinal necrosis. Lethal complications of pica include intestinal obstruction and perforation with peritonitis and generalized sepsis. Other findings at autopsy may include airway obstruction, heavy metal poisoning, and parasitic infestation. Presenting symptoms and signs of such complications may be subtle or masked given the nature of underlying conditions, and so careful evaluation of the medical histories of individuals with pica may be necessary to provide pertinent details of associated medical and psychiatric conditions.     

When benefitting a patient increases the risk for harm for third persons — The case of treating pedophilic Parkinsonian patients with deep brain stimulation

This paper investigates the question whether it is ethically justified to treat Parkinsonian patients with known or suspected pedophilia with deep brain stimulation — given increasing evidence that this treatment might cause impulse control disorders, disinhibition, and hypersexuality. This specific question is not as exotic as it looks at a first glance. First, the same issue is raised for all other types of sexual orientation or behavior which imply a high risk for harming other persons, e.g. sexual sadism. Second, there are also several (psychotropic) drugs as well as legal and illegal leisure drugs which bear severe risks for other persons. We show that Beauchamp and Childress' biomedical ethics fails to derive a veto against medical interventions which produce risks for third persons by making the patients dangerous to others. Therefore, our case discussion reveals a blind spot of the ethics of principles. Although the first intuition might be to forbid the application of deep brain stimulation to pedophilic patients, we argue against such a simple way out, since in some patients the reduction of dopaminergic drugs allowed by deep brain stimulation of the nucleus subthalamicus improves impulsive control disorders, including hypersexuality. Therefore, we propose a strategy consisting of three steps: (1) risk assessment, (2) shared decision-making, and (3) risk management and safeguards.     

Glamorizing sick bodies: how commercial advertising has changed the representation of HIV/AIDS

As a consequence of pharmaceutical advancements, HIV is no longer described in terms of the absence of health or presence of illness, and advertisements promoting anti-AIDS medications commercialize idealized and desirable bodies. The present study discusses representations of HIV/AIDS in commercial advertising and their change over time. The article traces the shift in AIDS/HIV representations in commercial advertising from the early 1990s, when images of decay and disease represented AIDS, to nowadays, when the wider availability of antiretroviral medications and their ability to prolong life produced new representations of HIV-afflicted bodies. Claiming that HIV individuals can lead a normal life where everything is possible, advertising has re-established the definition of a sick body. On the other hand, this marketing approach has important social implications because such representations minimize the seriousness of HIV infection and fail to take into account the real dangers of contracting HIV and to accurately represent the life with HIV and AIDS.
