Errors and countermeasures of robotic surgery system in thyroid surgery application / 国际外科学杂志

The purpose of minimally invasive thyroid surgery is to perform refined surgery through an intelligent operating system, achieving minimal physical and psychological trauma for patients, thereby improving their quality of life. At present, the commonly used minimally invasive surgical methods are laparoscopic surgery and robotic surgery, both by creating tunnels from a distance to the thyroid gland, requiring high technical requirements for surgical instruments and robotic surgeons. Regardless of the type of minimally invasive surgery, in the early stages of implementation, doctors have a process of exposure, understanding, proficient mastery, and innovative expansion of the system, instruments, operating methods, and surgical thinking. In this process, it is inevitable to encounter some erroneous operations, which are the main causes of medical safety adverse events, including complications, and bring a failed medical experience to patients. At the same time, mistakes can also cause psychological burden for robotic surgeons and have an impact on the development of new technologies. The occurrence of errors also depends on the open surgical experience and clinical adaptability of robotic surgeons, and experienced robotic surgeons can significantly reduce errors. With the innovation of medical technology and the urgent demand of patients for efficacy and beauty, errors should not be a factor hindering the development of minimally invasive thyroid surgery. This article will analyze the erroneous operations of robot surgeons, formulates countermeasures, and provides reference for the safe implementation of robot surgery, thereby promoting the development of intelligent precision minimally invasive surgery, and further benefiting patients with minimally invasive needs.

Prions:a threat to health security and the need for effective medical countermeasures / 《全球健康杂志（英文）》

Prions are infectious conformations of certain naturally occurring proteins.These misfolded proteins can struc-turally alter healthy protein,creating misfolded copies that repeat the process and form protein aggregates that lead to neuronal cell death.Although years can pass from initial prion infection to clinical presentation of symp-toms,onset of symptoms is typically followed by rapid neurological decline resulting in death.Prion diseases have been characterized in animals ranging from sheep and cattle to cervids and humans,with notable cross-species infections such as the variant Creutzfeldt-Jakob disease.Thus,prions present a health risk with the potential to disrupt major food sources as well affect human health through animal to human and human to human trans-mission events.While human to human prion transmission is rare and the immediate risks for a prion-facilitated pandemic are low,prions are a class of pathogens for which we are underprepared.In addition,prions,and prion disease-like approaches,have also been discussed in the context of biological weapons and toxins,adding another layer of complexity surrounding biosecurity and biodefense.These threats underscore the need for increased scrutiny and research on prions.Here,pharmaceutical and nonpharmaceutical prion-specific interventions are discussed.Recent advances in prion therapeutic development are also briefly highlighted,and a set of policy rec-ommendations are given that aims to provide high level suggestions for the prevention and mitigation of prion diseases.

The unexpected antibodies of blood plasma were screened by microcolumn gel card. The samples with positive antibodies were identified for alloantibody specificity. 【Results】 Unexpected antibodies were yielded in 67 out of 298(22.48%) transfused children with thalassemia. The positive rates of unexpected antibodies in boys and girls were 16.55%(24/145) and 28.10%(43/153), respectively. The positive rates of unexpected antibodies in Han, Dai, Zhuang, Yi, Bulang, Jinuo and Miao people were 14.06%(18/128), 30.80%(32/104), 35.71%(10/28), 36.36%(8/22), 50.00%(4/8), 60.00%(3/5)and 66.67%(2/3), respectively, with statistically significant differences between each other. The positive rate of unexpected antibodies in ethnic minorities was higher than that in Han. The positive rates of unexpected antibodies in children who received the first transfusion at birth-one year old, 1~3 years old, 3~6 years old and above 6 years old were 12.50%(3/24), 10.14%(7/69), 24.54%(40/163)and 40.48%(17/42), respectively. The positive rates of unexpected antibodies in children with first transfusion after 3 years old were significantly higher than those before 3 years old. The positive rates of unexpected antibodies in children with one transfusion, 1~3, 3~10, 10~20 and more than 20 transfusions were 4.76%(1/21), 12.07%(7/58), 23.71%(23/97), 28.16%(29/103)and 36.84%(7/19), respectively, with statistically significant differences between each other. The number of blood transfusions was positively correlated with the unexpected antibody yielding. The yielding rate of unexpected antibodies in children with α thalassemia, βthalassemia, δ+ βthalassemia and untyped thalassemia was 7.50%(3/40), 17.62%(34/193), 53.70%(29/54)and 9.09%(1/11), respectively(P<0.05). The yielding rate of unexpected antibodies in transfused children with δ+ βthalassemia was the highest. And 57 unexpected antibodies of Rh blood group system were yielded, 6 anti-M antibodies, 2 anti-N antibodies and 2 undetermined. 【Conclusion】 The positive rate of unexpected antibodies in transfused children with thalassemia in Yunnan province is high. Routine antibody screening should be carried out for transfusion children with thalassemia, and blood units, compatible with ABO, Rh and MNS typing results, should be selected to ensure the safety and effectiveness of clinical blood use.
