The Anti-Inflammatory and Anti-Nociceptive Activities of Patrinia Villosa and Its Mechanism on the Proinflammatory Cytokines of Rats with Pelvic Inflammation

This study explores the anti-inflammatory and anti-nociceptive activities of Patrinia villosa, a Chinese medicinal plant, and to explore its effects on the proinflammatory cytokines of the rats with pelvic inflammation model. The animals were randomly divided into Patrinia villosa group (PV group), dexamethasone group (DEX group), and model-control group (CON group) to perform an ear edema test, a carrageenin-induced paw edema test, a cotton pellet-induced granuloma formation test, and an acetic acid-induced writhing test. The model rats with pelvic inflammation were established, and the serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-α) in each group was detected with the Enzyme-Linked ImmunoSorbent Assay (ELISA). The results of the ear edema test, carrageenin-induced paw edema test, cotton pellet-induced granuloma formation test, and acetic acid-induced writhing test all showed that Patrinia villosa had strong anti-inflammatory and anti-nociceptive effects. In the experiment using model rats with pelvic inflammation, we found that the serum levels of IL-6, IL-8 and TNF-α in PV and DEX group were all significantly lower than those of the CON group, and the serum levels of IL-6 and IL-8 in PV group were significantly lower than those of the DEX group. Patrinia villosa, with its strong anti-inflammatory and anti-nociceptive activities, can be used to treat pelvic inflammation and to relieve the associated pain.     

Automated diagnosis of epilepsy using EEG power spectrum

Interictal electroencephalography (EEG) has clinically meaningful limitations in its sensitivity and specificity in the diagnosis of epilepsy because of its dependence on the occurrence of epileptiform discharges. We have developed a computer‐aided diagnostic (CAD) tool that operates on the absolute spectral energy of the routine EEG and has both substantially higher sensitivity and negative predictive value than the identification of interictal epileptiform discharges. Our approach used a multilayer perceptron to classify 156 patients admitted for video‐EEG monitoring. The patient population was diagnostically diverse; 87 were diagnosed with either generalized or focal seizures. The remainder of the patients were diagnosed with nonepileptic seizures. The sensitivity was 92% (95% confidence interval [CI] 85–97%) and the negative predictive value was 82% (95% CI 67–92%). We discuss how these findings suggest that this CAD can be used to supplement event‐based analysis by trained epileptologists.

应用抗甲状腺药物致粒细胞缺乏患者感染的临床研究

目的分析使用抗甲状腺药物(ATD)引起粒细胞缺乏及引发感染患者的临床特点和感染部位、病原菌分布及其耐药性。方法回顾性分析72例使用ATD引起粒细胞缺乏及引发感染患者的临床资料,采用SPSS11.0软件进行统计分析。结果 72例患者感染部位以呼吸道为主,占55.3%,其次为泌尿系、胃肠道,分别占21.1%和10.5%;共分离出病原菌52株,其中革兰阳性菌20株占38.5%;革兰阴性菌26株占50.0%;真菌6株占11.5%;革兰阳性菌对万古霉素和替考拉宁敏感性最高,分别为90.0%和100.0%,对其他抗菌药物均存在不同程度的耐药性;革兰阴性菌对美罗培南和亚胺培南敏感性最高,均为92.3%,对第三代头孢类药物、阿米卡星等存在不同程度的耐药性。结论使用ATD容易引起患者粒细胞缺乏,继而诱发各种感染,且感染部位以呼吸道最为常见,引起感染的病菌中革兰阴性菌与革兰阳性菌相当,真菌感染相对较少。

Serum vascular endothelial growth factor receptor 3 as a potential biomarker in psoriasis

To discover novel biomarkers of psoriasis, a target‐specific antibody array screening of serum samples from psoriasis patients was initially performed. The results revealed that vascular endothelial growth factor receptor 3 (VEGFR‐3) was significantly elevated in the sera of psoriasis patients, compared to healthy controls. Next, ELISA validation studies in a larger cohort of psoriasis patients (N = 73) were conducted, which confirmed that serum VEGFR‐3 was indeed significantly increased in patients with psoriasis compared to healthy controls (P < 0.001). Furthermore, receiver operating characteristic curve analysis demonstrated that serum VEGFR‐3 exhibited potential in distinguishing healthy controls from psoriasis patients: area under the curve = 0.85, P < 0.001. In addition, serum levels of VEGFR‐3 were correlated with Psoriasis Area Severity Index scores (R = 0.32, P = 0.008) in psoriasis patients. Interestingly, serum VEGFR‐3 levels were significantly elevated in psoriatic arthritis compared to non‐psoriatic arthritis (P = 0.026). A pilot longitudinal study demonstrated that serum levels of VEGFR‐3 could reflect disease progression in psoriasis. Collectively, serum VEGFR‐3 may have a clinical value in monitoring disease activity of psoriasis.
