Myelin ultrastructure of sciatic nerve in rat experimental autoimmune neuritis model and its correlation with associated protein expression

To explore the relationship of peripheral nerve ultrastructure and its associated protein expression in experimental autoimmune neuritis (EAN). EAN was established in Lewis rats using an emulsified mixture of P0 peptide 180-199, Mycobacterium tuberculosis, and incomplete Freund’s adjuvant. Rats immunized with saline solution were used as a control group. Sciatic nerve ultrastructure and immunofluorescence histopathology were measured at the neuromuscular severity peak on day 18 post-induction. Cell-specific protein markers were used for immunofluorescence histopathology staining to characterize sciatic nerve cells: CD3 (T cell), Iba-1 (microglia), S100 (myelin), and neurofilament 200 (axon). The results showed that swelling of the myelin lamellae, vesicular disorganization, separation of the myelin lamellae, and an attenuation or disappearance of the axon were observed by transmission electron microscopy in the EAN group. CD3 and Iba-1 increased significantly in the structures characterized by separation or swelling of the myelin lamellae, and increased slightly in the structures characterized by vesicular of the myelin lamellae, S100 decreased in the structures characterized by vesicular disorganization or separation of the myelin lamellae. And neurofilament 200 decreased in the structures characterized by separation of the myelin lamellae. Furthermore, we found that Iba1 were positive in the myelin sheath, and overlapped with S100, which significantly indicated that Schwann cells played as macrophage-like cells during the disease progression of ENA. Our findings may be a significant supplement for the knowledge of EAN model, and may offer a novel sight on the treatment of Guillain-Barré syndrome.

Esophageal space-occupying lesion caused by Ascaris lumbricoides

Ascaris lumbricoides is the largest intestinal nematode parasite of man, which can lead to various complications because of its mobility. As the esophagus is not normal habitat of Ascaris, the report of esophageal ascariasis is rare. An old female presented with dysphagia after an intake of several red bean buns and haw jellies. The barium meal examination revealed a spherical defect in the lower esophagus. Esophageal bezoar or esophageal carcinoma was considered at the beginning. The patient fasted, and received fluid replacement treatment as well as some oral drugs such as proton pump inhibitor and sodium bicarbonate. Then upper gastrointestinal endoscopy was done to further confirm the diagnosis and found a live Ascaris lumbricoides in the gastric antrum and two in the duodenal bulb. The conclusive diagnosis was ascariasis. The esophageal space-occupying lesion might be the entangled worm bolus. Anthelmitnic treatment with mebendazole improved patient's clinical manifestations along with normalization of the radiological findings during a 2-wk follow-up. Authors report herein this rare case of Ascaris lumbricoides in the esophagus, emphasizing the importance of awareness of this parasitic infection as it often presents with different and unspecific symptoms.

Transplantation of miRNA‐34a overexpressing adipose‐derived stem cell enhances rat nerve regeneration

Peripheral nerve injury is an ongoing challenge in reconstructive surgery. Adipose‐derived stem cell (ADSC) application is reported to improve nerve regeneration. In the present study, we evaluated the potential benefit of 34a‐ADSCs for never regeneration. Lentiviral vectors containing miRNA‐34a were constructed and ADSCs were transduced. The obtained 34a‐ADSCs were used to regenerate the sciatic nerve in surgically induced sciatic nerve injury rat model. Sprague–Dawley (SD) rats were randomly divided into two groups, a 34a‐ADSC group and an Lv‐ADSC group. Functional nerve recovery was assessed by walking track analysis at 12 weeks after surgery. In addition, histology, including light microscopy and transmission electron microscopy, and immunohistochemistry, was utilized to investigate the nerve repair effects of 34a‐ADSC. Results showed that reconstruction of the injured sciatic nerve had been significantly enhanced by restoration of nerve continuity and functional recovery in the 34a‐ADSC group compared with the Lv‐ADSC group. Furthermore, sciatic nerve conduction velocity and compound nerve action potential in the 34a‐ADSC group was much higher than that in the Lv‐ADSC group (30.72 ± 2.95 m/s vs. 22.73 ± 1.91 m/s, p< 0.0001; 11.93 ± 0.76 mV vs. 9.52 ± 0.53 mV, p = 0.0418). This study raises the possibility of using miRNA‐34a overexpressed ADSCs as a promising alternative for nerve regeneration.     

Endoscopic decompression of the optic canal for traumatic optic neuropathy

Purpose: Traumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%e5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries. Methods: In this study, 11 patients treated in our hospital from January 2009 to January 2015 with the visual loss resulting from TON were retrospectively reviewed for preoperative vision, visual evoked potential (VEP) scan, surgical approach, postoperative visual acuity, complications, and follow-up results. Results: All these patients received endoscopic decompression of the optic canal. At the 3-month followup, the visual acuity improvement rate of the 11 patients was 45.5%. The vision acuity of 2 cases improved from hand movement to 0.08 and 0.3 after operation. Another patient''s vision acuity returned to 0.05 compared to light sensation preoperatively. Two cases had finger counting before surgery but they had a vision acuity of 0.4 and light sensation respectively after surgery. However, the other 6 cases'' vision did not improve after surgery. Conclusion: Endoscopic decompression of the optic canal is an effective way to cure TON. VEP could be used as an important reference for preoperative and prognosis evaluation. Operative time after trauma is only a relative condition that may affect the therapeutic effect of optic canal decompression. Poor results of this procedure may be related to the severity of the optic nerve injury.
