中药胃管注入治疗肠梗阻临床观察

目的观察中药胃管注入治疗肠梗阻的临床疗效。方法将114例肠梗阻患者随机分为研究组和对照组,每组57例。对照组仅给予外科基础治疗,研究组在对照组疗法基础上辨证给予具有行气活血通腑、活血解毒通腑、健脾润肠功效的中药经胃管注入治疗。治疗结束后观察两组临床疗效和中转手术率。结果研究组临床疗效显著优于对照组(P0.05),中转手术率显著低于对照组(P0.05)。结论在外科基础治疗之上,经胃管辨证给予具有行气、活血、解毒、通腑、健脾、润肠功效的中药能提高肠梗阻的临床疗效,降低中转手术率。

肝水解肽注射液反相高效液相色谱特征研究

目的 研究肝水解肽注射液的反相高效液相色谱（reverse phase high performance liquid chromatography, RP HPLC）特征。方法 采用RP HPLC/紫外光谱（ultraviolet spectrum, UV）法分离肝水解肽注射液的主要成分。色谱条件：0.1％三氟乙酸水溶液和0.1％三氟乙酸乙腈 0.1％三氟乙酸水溶液（80∶20）,进行梯度洗脱,流速为1.0 ml/min;检测波长214 nm。用中药指纹图谱相似度评价软件对所得图谱进行评价。结果 相同厂家不同批号产品特征图谱与均谱相似度均在0.95以上;不同厂家产品特征图谱与均谱的相似度在0.93以上。结论 所建立的RP HPLC方法具有较好的分离能力,线性、精密度良好;企业制剂批间一致性良好,不同来源动物肝脏用不同酶的水解产物几乎无差异。本实验为肝水解肽注射液的质量控制提供了有效的方法。     

Death following injection sclerotherapy due to phenol toxicity

Prolapse rectum (PR) or protrusion of the rectum beyond the anus occurs frequently in populations at both extremes of age. In the pediatric population, in developed countries, the commonest cause for PR is thought to be cystic fibrosis (CF). Treatment options for CF include conservative management, surgical resection and fixation, suturing, and injection sclerotherapy (IS). The last is considered an attractive treatment option because it is minimally invasive. In this case report, the authors present the details about a 2-year-old female child, with PR and CF, who died after IS, using phenol as the sclerotherapeutic agent. Autopsy findings and toxicology tests performed to establish phenol toxicity are documented. The available literature is reviewed. This case report underscores the risks of using phenol for IS and emphasizes the point that the procedure is not innocuous and an adverse outcome including fatality is a possibility.     

Maximizing order or harm? Arrests among a social network of people who inject drugs in a large urban city

Encountering the criminal justice system at the first point of entry---an arrest---is associated with heightened HIV and Hepatitis risk behavior among people who inject drugs (PWIDS). Intervening structurally through the criminal justice system impacts public health; therefore, determining arrest patterns is an important tool for risk reduction. Among a sample of 740 PWIDs, and their social network members recruited from predominantly African-American neighborhoods in Baltimore City, a third were recently arrested in the previous six months, and of those, the arrests were disproportionately African-American persons and characterized as nonviolent, i.e., drug possession/attempt to purchase (38%) and loitering (29%). Poisson regression models were built adjusted for age, sex, race, education level, homelessness, and monthly income after exploring bivariable characteristics of arrests using chi-squared tests. Active drug use was associated with a recent arrest (adjusted prevalence ratio: aPR 2.38 95% CI 1.6, 3.6), in addition to participants who recently reported attending a syringe exchange program (aPR 1.45 95% CI 1.1, 2.0). Our findings are suggestive of recent media coverage and burgeoning research revealing the prioritization of policing resources toward both communities of color and neighborhoods of intensified drug trafficking. Further research is warranted to contextualize the operationalization of criminal justice resources and the impact on community health.     

Dr. Death? Professionalism,Virtue, and U.S. Physician Participation in the Death Penalty

In the United States at present, the death penalty is a possible sentence in 31 out of 50 states, as well as within the military and for federal cases. In the U.S., numbers of executions are declining, in part due to moratoriums in place and challenges to execution by lethal injection. Participation by physicians in lethal injection executions has been steadfastly viewed by professional medical organizations as contrary to their ethical standards. However, physicians have participated in lethal injection executions, and the morality of the death penalty itself is a matter of intense social and political debate. Medical ethics commentators and professional organizations have typically held that the prohibition on physician participation in the death penalty is independent of the ethical status of the death penalty itself. This article argues that this view is untenable, and that it is tied to a view of professional role virtue that is similarly untenable. At the same time, it argues that, given the morally uncertain status of the death penalty, it is plausible that virtuous physicians may either refuse or choose to participate in some aspects of the death penalty.     

论我国注射死刑的平等适用

目前,我国在执行注射死刑时存在不能完全平等适用的问题。这种不平等适用体现为不同身份的死刑犯适用不平等、不同地区的死刑犯适用不平等、不同罪行的死刑犯适用不平等等方面。注射死刑不平等适用违反了法律面前人人平等原则,引起社会的诸多质疑。而注射死刑未平等适用的原因较为复杂,既因立法上存在漏洞,又受到注射成本过高,地方司法机关推动力度不够,民众报应观念较强等因素制约。
