Neuropathic pain is an important medical problem with few effective treatments. The sigma 1 receptor (σ1R) is a potential target for neuropathic pain therapeutics, and antagonists for this receptor are effective in preclinical models and are currently in phase II clinical trials. Relatively little is known about the σ2R, which has recently been identified as transmembrane protein 97 (Tmem97). We generated a series of σ1R and σ2R/Tmem97 agonists and antagonists and tested them for efficacy in the mouse spared nerve injury (SNI) model...

Noxious stimulation of sensory afferents evokes phosphorylated extracellular signal regulated kinase (pERK) expression in spinal cord neurons. This study investigated the expression of pERK in the dorsal horn neurons in response to innocuous and noxious cold stimuli in naïve versus spared nerve injury (SNI) rats. Noxious cold or hot stimuli (0 or 45°C) elicited pERK expression in laminae I-II whereas cooling stimuli from 32°C to 25, 15 or 5°C produced no or little pERK expression in dorsal horn neurons...

This paper aims to discuss the clinical significance of laparotomy nerve sparing radical hysterectomy (NSRH) on rectal function of early cervical cancer patients, compared with conventional radical hysterectomy. 30 cases of early cervical carcinoma patients who had received surgery in the First Affiliated Hospital of Zhengzhou University from June 2010 to June 2014 were selected as subjects. Patients were divided into two groups, with 15 in each gorup, in which Group A had received NSRH, B received CRH, and all them were in stage IB-IIA1...

Laparoscopic surgery is proven equal technique to open rectal surgery. Despite advantages, some problems in case of low rectal surgery are existing: visualization of the pelvis, securing safe distal resection margin, preparing single stapled rectal stump with safe conjunction to the colorectal anastomosis. Approximately 500 procedures have been performed worldwide until today by applying Transanal Total Mesorectal Excision (TaTME) technique, which evolved from a combination of laparoscopy and transanal approach...

BACKGROUND: Liver X receptors, including α and β isoforms, are ligand-activated transcription factors. Whether liver X receptor α plays a role in neuropathic pain is unknown. METHODS: A spared nerve injury model was established in adult male rats and mice. Von Frey tests were performed to evaluate the neuropathic pain behavior; Western blot and immunohistochemistry were performed to understand the underlying mechanisms. RESULTS: Intrathecal injection of a specific liver X receptor agonist T0901317 or GW3965 could either prevent the development of mechanical allodynia or alleviate the established mechanical allodynia, both in rats and wild-type mice...

Post-traumatic brachial plexopathies can occur following displaced proximal humeral fractures, causing profound functional deficits. Described here is an unusual case of a displaced proximal humeral metaphyseal fracture in a young child. The patient underwent closed reduction and serial casting, but hand weakness and forearm sensory loss persisted. Needle EMG localized the injury to the mid/proximal arm near the fracture site, resulting in damage to the posterior and medial cords of the brachial plexus with profound involvement of the radial, ulnar, and median nerves and sparing of the axillary nerve...

Although pain is frequently accompanied with depression, little is known about the risk factors contributing to individual differences to the comorbidity of pain and depression. In this study, we examined whether cytokines and brain-derived neurotrophic factor (BDNF) might contribute to the individual differences in the development of neuropathic pain-induced depression. Rats were randomly subjected to spared nerved ligation (SNI) or sham surgery. The SNI rats were divided into two groups by the data from depression-related behavioral tests...

BACKGROUND: Most patients with head and neck skin tumors present with normal facial nerve function. A common treatment strategy for these patients is facial nerve preservation surgery, although the degree to which the nerve is successfully preserved is still unclear. Data on the incidence and recovery of facial nerve dysfunction are woefully lacking in the field of dermato-oncology. METHODS: In 23 patients with normal preoperative facial nerve function, we retrospectively reviewed twenty-six head and neck surgical interventions that included facial nerve exposure and protection, focusing particularly on the differences in outcome between intraparotid and extraparotid exposure of the facial nerve branches...

PURPOSE: Managing juxtapapillary and circumpapillary choroidal melanoma with brachytherapy is challenging because of technical complications with accurate plaque placement and high radiation toxicity given tumor proximity to the optic nerve. We evaluated our center's experience using ultrasound-guided, Iodine (I)-125 notched plaque brachytherapy for treating choroidal melanoma contiguous with (juxtapapillary) and at least partially surrounding the optic disc (circumpapillary). METHODS: All cases of choroidal melanoma treated with I-125 notched plaque brachytherapy at our center from September 2003-December 2013 were retrospectively reviewed...

BACKGROUND: Multiple system atrophy (MSA) is a rare, adult-onset, rapidly progressive fatal synucleinopathy that primarily affects oligodendroglial cells in the brain. Patients with MSA only rarely have visual complaints, but recent studies of the retina using optical coherence tomography (OCT) showed atrophy of the peripapillary retinal nerve fiber layer (RNFL) and to a lesser extent the macular ganglion cell layer (GCL) complex. METHODS: We performed a literature review and meta-analysis according to the preferred reporting items for systematic reviews and meta-analyses guidelines for studies published before January 2017, identified through PubMed and Google Scholar databases, which reported OCT-related outcomes in patients with MSA and controls...

The heptapeptide SP1-7 (1, Arg(1)-Pro(2)-Lys(3)-Pro(4)-Gln(5)-Gln(6)-Phe(7)) is the major bioactive metabolite formed after proteolytic processing of the neuropeptide substance P (SP, Arg(1)-Pro(2)-Lys(3)-Pro(4)-Gln(5)-Gln(6)-Phe(7)-Phe(8)-Gly(9)-Leu(10)-Met(11)-NH2). The heptapeptide 1 frequently exhibits opposite effects to those induced by SP, such as exerting antinociception, or attenuating thermal hyperalgesia and mechanical allodynia. The heptapeptide SP1-7 amide (2, Arg(1)-Pro(2)-Lys(3)-Pro(4)-Gln(5)-Gln(6)-Phe(7)-NH2) is often more efficacious than 1 in experimental pain models...

INTRODUCTION: The International Index of Erectile Function (IIEF) is the gold standard validated instrument for defining erectile function (EF) and its response to treatment. The EF domain (EFD) contains six questions and is a sensitive and specific measurement of treatment-related changes in EF. The EFD score has been widely used as a primary assessment end point for clinical trials of EF recovery after radical prostatectomy (RP). Various EFD scores have been used to define functional erections...

INTRODUCTION: Indocyanine green (ICG) is a fluorescent molecule that provokes detectable photon emission. The use of ICG with near-infrared (NIR) imaging system (Akorn, Lake Forest, IL) has been described during robotic partial nephrectomy (RAPN) as an adjunctive means of identifying renal artery and parenchymal perfusion.We propose the use of the ICG with NIR fluorescence during laparoscopic robot-assisted radical prostatectomy (RARP), to identify the benchmark artery improving the preservation of neurovascular bundle and to improve the visualization of the vascularization and then the hemostasis...

OBJECTIVE: To report an unusual lateral medullary stroke (LMS) associated with transient unidirectional horizontal, nystagmus, and decreased horizontal vestibulo-ocular reflex (h-VOR) gain that mimicked a peripheral vestibulopathy. MRI suggested involvement of caudal medial vestibular nucleus (MVN); however, the rapid resolution of the nystagmus and improved h-VOR gain favored transient ischemia without infarction. Decreased h-VOR gain is expected with peripheral vestibular lesions within the labyrinth or superior vestibular nerve; less frequently lateral pontine strokes involving the vestibular root entry, the vestibular fascicle, or neurons within the MVN may be responsible...
