目的:分析延续护理干预对慢性乙型肝炎患者抗病毒治疗依从性的影响。方法:研究选取2017年1月~2017年12月某院肝二病区收治的112例乙型肝炎患者和2018年1月~2018年12月收治的98例乙型肝炎病毒患者作为研究对象,所有患者均进行抗病毒治疗,回顾性分析患者的病历资料。将2017年收治的112例患者作为常规组实施常规护理,将2018年收治的98例患者的作为研究组实施延续性护理,比较两组的护理效果。结果:研究组的治疗依从率为93.88%(92例),远高于常规组的77.68%(87例),两组数据比较存在统计学意义(P<0.05)。结论:延续性护理措施可以有效提高慢性乙型肝炎抗病毒治疗的依从性,可以在临床中推广使用。     

我国类鼻疽病的流行病学特征及诊疗的研究进展

类鼻疽病是由类鼻疽伯克霍尔德菌(Burkholderia pseudomallei)感染引起的一类人畜共患病,主要流行于全球热带及亚热带地区。在我国主要流行于南部地区,疫源地为海南、广东、广西、台湾等。伴随着旅游业和贸易业的发展,我国其他非疫区出现了输入性病例。类鼻疽病的感染途径主要为经伤口、粘膜、呼吸道、消化道等,其病变可涉及机体所有器官,易造成较高的误诊率和病死率。然而我国目前类鼻疽病的流行病筛查技术存在一定的局限性,在防控方面未实行有效的疾病监测和疾病报告制度,对基层医师和民众疾病知识普及的力度不够。因此,本文旨在提高我国医务工作者对类鼻疽病的重视程度,从类鼻疽病的病原学特征、流行病学特征、临床特征、诊断与治疗、防控措施这五个方面进行详细综述。     

Osteoarthritis today: Lost in translation?

Osteoarthritis (OA) is a highly prevalent joint disease that is associated with pain, loss of function, and high direct and indirect economic costs. The current therapeutic options are inadequate, providing only a moderate symptom relief without the possibility of disease modification. While treatment options and personalized medicines are increasing for many complex diseases, OA drug development has been impeded by the advanced state of disease at the time of diagnosis and intervention, heterogeneity in both symptoms and rates of progression, and a lack of validated biomarkers and relevant outcome measures. This review article summarizes the OA landscape, including therapies in development as potential OA treatments, potential biomarkers undergoing evaluation by the US Food and Drug Administration, and a summary of current OA treatment guidelines, with a particular focus on the knee OA.     

输卵管积水对体外受精-胚胎移植的影响和治疗

近年来越来越多的研究证实输卵管积水对IVF-ET结局有负面影响,主要表现为着床率和妊娠率降低以及异位妊娠率和流产率升高。输卵管积水可能通过机械性作用、胚胎毒性、降低子宫内膜容受性和卵巢功能等影响IVFET妊娠结局。IVF-ET前对输卵管积水进行治疗处理,可提高妊娠率,改善妊娠结局。但是因为各种手术的利弊和患者的个体差异,目前对于输卵管积水的处理原则尚不统一。中医药治疗可采用多种方法治疗输卵管积水,有一定的临床疗效和治疗优势。手术和IVF-ET治疗前后可联合中医药疗法,中西医结合治疗更有助于提高IVF-ET成功率。     

Photoacoustic treatment mitigates cognitive dysfunction in a model of sleep-wake rhythm disturbance

Sleep-wake rhythm disturbances,which are characterized by abnormal sleep timing or duration,are associated with cognitive dysfunction.Photoacoustic treatments including light and sound stimulation have been found to be effective in modulating sleep patterns and improving cognitive behavior in abnormal sleep-wake pattern experiments.In this study,we examined whether light and sound interventions could reduce sleep-wake pattern disturbances and memory deficits in a sleep rhythm disturbance model.We established a model of sleep rhythm disturbance in C57 BL/6 J mice via a sleep deprivation method involving manual cage tapping,cage jostling,and nest disturbance.We used a Mini Mitter radio transmitter device to monitor motor activity in the mice and fear conditioning tests to assess cognitive function.Our results indicated that an intervention in which the mice were exposed to blue light(40-Hz flickering frequency)for 1 hour during their subjective daytime significantly improved the 24-hour-acrophase shift and reduced the degree of memory deficit induced by sleep deprivation.However,interventions in which the mice were exposed to a 40-Hz blue light at offset time or subjective night time points,as well as 2 Hz-blue light at 3 intervention time points(subjective day time,subjective night time,and offset time points),had no positive effects on circadian rhythm shift or memory deficits.Additionally,a 2000-Hz sound intervention during subjective day time attenuated the24-hour-acrophase shift and memory decline,while 440-Hz and 4000-Hz sounds had no effect on circadian rhythms.Overall,these results demonstrate that photoacoustic treatment effectively corrected abnormal sleep-wake patterns and cognitive dysfunction associated with sleep-deprivation-induced disturbances in sleep-wake rhythm.All animal experiments were approved by the Experimental Animal Ethics Committee of Drum Tower Hospital Affiliated to the Medical College of Nanjing University,China(approval No.20171102)on November20,2017.     

Endogenous motion of liver correlates to the severity of portal hypertension

BACKGROUND Degree of portal hypertension(PH) is the most important prognostic factor for the decompensation of liver cirrhosis and death, therefore adequate care for patients with liver cirrhosis requires timely detection and evaluation of the presence of clinically significant PH(CSPH) and severe PH(SPH). As the most accurate method for the assessment of PH is an invasive direct measurement of hepatic venous pressure gradient(HVPG), the search for non-invasive methods to diagnose these conditions is actively ongoing.AIM To evaluate the feasibility of parameters of endogenously induced displacements and strain of liver to assess degree of PH.METHODS Of 36 patients with liver cirrhosis and measured HVPG were included in the casecontrol study. Endogenous motion of the liver was characterized by derived parameters of region average tissue displacement signal(dantero, dretro, d RMS) and results of endogenous tissue strain imaging using specific radiofrequency signal processing algorithm. Average endogenous strain μ and standard deviation σ of strain were assessed in the regions of interest(ROI)(1 cm × 1 cm and 2 cm × 2 cm in size) and different frequency subbands of endogenous motion(0-10 Hz and 10-20 Hz).RESULTS Four parameters showed statistically significant(P 0.05) correlation with HVPG measurement. The strongest correlation was obtained for the standard deviation of strain(estimated at 0-10 Hz and 2 cm × 2 cm ROI size). Three parameters showed statistically significant differences between patient groups with CSPH, but only dretro showed significant results in SPH analysis. According to ROC analysis area under the curve(AUC) of the σROI[0…10 Hz, 2 cm × 2 cm] parameter reached 0.71(P = 0.036) for the diagnosis of CSPH; with a cut-off value of 1.28 μm/cm providing 73% sensitivity and 70% specificity. AUC for the diagnosis of CSPH for μROI[0…10 Hz, 1 cm × 1 cm] was 0.78(P = 0.0024); with a cut-off value of 3.92 μm/cm providing 73% sensitivity and 80% specificity. Dretro parameter had an AUC of 0.86(P = 0.0001) for the diagnosis of CSPH and 0.84(P = 0.0001) for the diagnosis of SPH. A cut-off value of-132.34 μm yielded 100% sensitivity for both conditions, whereas specificity was 80% and 72% for CSPH and SPH respectively.CONCLUSION The parameters of endogenously induced displacements and strain of the liver correlated with HVPG and might be used for non-invasive diagnosis of PH.     

Topical tacrolimus therapy in the management of lower extremity ulcers due to prolidase deficiency

Prolidase deficiency is a rare autosomal recessive disorder characterized by cutaneous ulcers, facial dysmorphism, recurrent infections, and intellectual disability. We report a unique case of a 6‐year‐old boy with prolidase deficiency and Crohn's disease who presented with lower extremity ulcers. Cutaneous ulcers due to prolidase deficiency are historically resistant to treatment, and we report success with the novel use of topical tacrolimus.
