嘌呤能受体X1与肺腺癌预后及免疫细胞浸润的相关性研究

目的：探索嘌呤能受体X1(purinergic receptor，P2RX1)与肺腺癌(LUAD)患者预后及免疫细胞浸润的相关性。方法：利用生物信息学技术分析非小细胞肺癌中P2RX1的表达及其甲基化与患者预后的关系，对P2RX1共表达基因进行富集分析并筛选核心基因。利用TIMER 2.0数据库、R软件等分析P2RX1与免疫细胞、免疫检查点、免疫基质评分等的相关性。结果：P2RX1在LUAD中表达下调，低表达P2RX1的患者预后较差(P<0.05)，且P2RX1与肿瘤纯度、分期等临床病理因素有关(P<0.05)。P2RX1的表达与肺鳞癌患者预后无明显相关。Cg06475633等P2RX1 CpG位点甲基化与患者预后相关。P2RX1共表达基因主要富集于免疫细胞活化、分化等通路和生物学进程，核心基因主要包括BTK、IKZF1等。P2RX1的表达与B细胞浸润、免疫/基质评分、PD-1、CTLA-4等多个免疫检查点显著相关(P<0.05)。结论：P2RX1有望成为LUAD诊断和免疫治疗的新靶点。

Simultaneous detection of Aspergillus nidulans,Aspergillus luchuensis and Lichtheimia sp. in a bovine abortion

Abortion in dairy cattle may be caused by infectious (viruses, fungi and protozoa) and non-infectious causes mostly related to bad management practices and genetic factors. Recently, the significant contribution of mycotic infection to bovine abortion has been recognized. This report describes an abortion case in a Chianina cow due to Aspergillus nidulans, Aspergillus luchuensis and Lichtheimia sp. diagnosed by histology, cytology, culture and molecular assays. A mixed infection due to more than one fungus in abortion is rarely demonstrated. To our knowledge, this is the first case of bovine abortion caused by co-infection with three different moulds.     

Cerebral phaeohyphomycosis due to Cladophialophora bantiana in a French Guianese child

We report a case of cerebral phaeohyphomycosis, a fungal brain infection due to a dark (dematiaceous) fungi in a 6-year-old French Guyanese boy. The child presented fever and drowsiness due to several paraventricular brain abscesses. Neurological surgeries were performed to reduce intracranial hypertension and to obtain abscess biopsies. Mycological cultures of intraoperative samples led to the diagnosis of cerebral phaeohyphomycosis due to Cladophialophora bantiana. The patient neurological status deteriorated and remained critical after several weeks of combination antifungal therapy with voriconazole 8 mg/kg/day, liposomal amphotericin B 10 mg/kg/day and flucytosine 200 mg/kg/day. A complete surgical resection was not possible because of multiple small abscesses. A multidisciplinary ethical staff decided on home medical care with palliative ventriculoperitoneal shunt, nasogastric feeding and analgesics. One year later, the patient's neurological condition had improved and cerebral lesions had regressed, while he had not received any antifungal treatment but only traditional medicines. Cerebral phaeohyphomycosis are rare diseases affecting immunocompromised but also apparently non-immunocompromised patients, as in this case. A complete surgical resection is not always possible and mortality rates are high in spite of treatments with a combination of antifungals. The diagnosis may be difficult because of these dematiaceous fungi's slowly growing and their potential pathogenicity for laboratory staff.     

加速康复外科理念应用于甲状腺癌手术100例

目的 观察加速康复外科(ERAS)在甲状腺癌手术患者围手术期的应用效果。 方法 选取行双侧甲状腺癌根治术的患者150例,随机分为ERAS组(100例)、常规手术组(50例)。ERAS组围手术期采取一系列符合加速康复理念的优化措施,非ERAS组采取传统术前准备措施。比较两组术后疼痛评分、术后恶心、术后住院时间、住院费用、并发症等指标。 结果 ERAS组患者术后疼痛评分、恶心发生例数均较低,引流管拔除时间、住院时间短,住院费用减少;其他术后并发症发生例数均较少且差异无统计学意义。 结论 甲状腺癌手术患者围手术期采用ERAS理念处理可明显降低术后疼痛、恶心等不适,缩短住院时间,节省住院费用。     

‘Digital Dancing’ – “Can you see,what I feel” – An exploration of the physical ‘experience’ of dance for Parkinson’s through 3-dimensional motion analysis

Background: Parkinson’s is a common, progressive, neurodegenerative movement disorder of the central nervous system. Research has consistently shown that dancing can have a positive impact on the lives of people living with Parkinson’s (PwP).PwP who dance report that current measurement of the effects fails to appreciate the multifactorial presentation of the condition as well as the biopsychosocial potential of dance holistically.Aim: To explore the feasibility of combining measurements of whole-body movement using 3-dimensional motion analysis with the lived experience of dance for PwP, to see if it is possible to ‘see (measure)’ what PwP say they ‘feel (experience)’ when dancing, in a ‘mind/body approach’Method: Thirteen PwP and ten Carers took part in three community delivered ‘Parkinson’s Dance Science’ classes followed by focus group reflection. Three PwP wore a 3-dimensional, motion capture suit that recorded whole-body movement throughout the class and were interviewed about their experiences.Data were analysed using a ‘Convergent Parallel’ mixed methods design, mapping participant’s experiences and reflections over six biomechanical movement variables.Results: Quantitative results indicate that it is possible to use 3-dimensional motion capture to measure biomechanical change during and following dance in PwP but the amount and direction of change was different for each participant.Qualitative results showed PwP felt the methods were feasible and reported a positive immediate and long-term effect of dance in a complete ‘mind/body experience’.The sample size did not permit further analysis, but areas of development suggest it may not be the change in physical ability that is important, but more the perception of change following dance that is unique to each individual. Thus single measures of the effects of dance for PwP are likely to be insufficient when trying to understand the effect holistically.Conclusion: A ‘Convergent Parallel’ mixed methods research design, mapping the experience of dance for PwP (‘what I feel’) and their peers against biomechanical change (‘what you see’) following dance is feasible.Further research is required to develop the method with a larger sample to truly begin to understand the potential and effects of dance for PwP.     

Vacuum myofascial therapy device for non-specific neck pain. A single blind randomized clinical trial

ObjectivesThis study aimed to investigate the efficacy of a vacuum myofascial therapy device (VT) for improving pressure pain thresholds (PPTs), range of motion (ROM), neck pain-related disability, pain, and quality of life in patients with non-specific neck pain.MethodsA randomized controlled trial in which thirty-eight participants with non-specific neck pain (NP) were randomly assigned to either an experimental (VT) or a comparison physical therapy program (PTP) group. The VT group (n = 19) received five sessions of treatment with a vacuum myofascial therapy device while the PTP group (n = 19) received five sessions of massage, ultrasound therapy (US), and transcutaneous electric nerve stimulation (TENS) over two weeks. The outcome measures were the numerical pain rating scale (NPRS), range of motion, quality of life (SF-12), neck disability Index (NDI), and PPTs at the end of treatment and at one-month follow-up.ResultsAlthough both groups experienced improvements in pain, neck disability, range of motion, and pressure pain, these only were statistically significant in the VT group. At one-month follow-up, the VT group still showed improvements in pain, neck disability, and range of motion.DiscussionVacuum myofascial therapy applied with a device offers similar results to other vacuum-based techniques such as cupping therapy. Moreover, in this device the parameters are digitally controlled, which allows for the precise reproduction of treatment.
