ObjectiveTo investigate the pathologic characteristics of the sural nerve in amyotrophic lateral sclerosis. MethodsClinical, electrophysiologic, laboratory data and sural nerve biopsy of 11 patients were reviewed. The clinical and laboratory data were compatible with the diagnosis of ALS. The sural nerve was removed and immediately fixed in 10% formalin and phosphate-buffered 2.5% glutaraldehyde and processed according to the procedure used in our laboratory for light and ultrastructural examination.Results4 groups were distinguished based on pathologic changes: normal; with mild axon degeneration and demyelination; with mild loss of the myelinated nerve, axon degeneration and demyelination; with severe loss of the myelinated nerve, axon degeneration and demyelination.ConclusionPredominantly axonal neuropathies are common and occur early in ALS. Axon degeneration of the nerve fibers is predominant, and demyelination also can be performed in patients with ALS.

Objective To explore the characters of lower urinary tract symptoms (LUTS) in patients with Parkinson's Disease (PD).Methods From Oct 2013 to Jun 2016,after evaluating of movement disorder by modified Hoehn-Yahr(H-Y) scale and LUTS by international prostate symptom score (IPSS),urodynamic study was performed in PD patients with LUTS.The incidence of every symptom of LUTS,the relationships between the IPSS categories and urodynamic study were analyzed.Results 64 patients (containing 26 male and 38 female) with 40-80 (62.7 ± 10.2) years old were included.2,4,30,19,12 and 6 patients were belonged to modified H-Y scale 1-4,respectively.Frequency (50 patients,78.1%) was the most common LUTS,while frequency all day (20 patients,31.3%) was the most common symptom for the most severe LUTS.IPSS was 1 7.5 ± 7.8 (4-35) and quality of life was 5.1 ± 0.6 (4-6) for the patients.There was no significant correlation between modified H-Y scale and IPSS (P > 0.05).According to the criteria of IPSS,28 patients (43.8%) only had irritative symptoms,3 patients (4.7%) only had obstructive symptoms,while 26 patients (40.6%) had mixed symptoms and 7 patients (10.9%) belonged to no one.Urodynamic study showed 11 patients (39.3%) with only irritative symptoms had detrusor overactivity(DO),6 patients (23.1%) with mixed symptoms had DO + bladder outlet obstruction (BOO) or DO + detrusor underactivity,however,there was no one with BOO in the three patients with only obstructive symptoms.Conclusion Frequency was the most common LUTS,while frequency all day was the most common symptom for the most severe LUTS in PD patients.Irritative and mixed symptoms were common in PD patients with LUTS,but the urodynamic results were not consistent with the category of LUTS in most of the patients.LUTS severity was not correlated with movement disorders in PD patients.

Objective: To investigate the prevalence of Calodium hepaticum (C. hepaticum) in rodents and insectivores from Wuhan section of the Yangtze River in China, and to provide evidence for the prevention and treatment of hepatic Calodium infection. Methods: Rodents and insectivores were captured from three selected Yangtze River beaches using mousetraps. The three survey sites were divided into six areas according to natural conditions, with 60 mousetraps placed in each area. The liver lesions in the captured rodents were observed by the naked eye and the eggs in the liver tissue were observed by microscopic examination. Results: A total of 1 080 mousetraps were placed, and 1 075 mousetraps were retrieved, with the retrieve rate as 99.5%. A total of 101 Apodemus agrarius, 12 Rattus norvegicus, and 9 Crocidura attenuata were caught. The average density of rodents and insectivores was 10.5% and 0.8%, respectively. DNA of egg nodules from infected rodents showed 98% similarity with that of C. hepaticum 18S rRNA (LC425008.1). One Rattus norvegicus was infected with C. hepaticum, with an infection rate of 3.23% in the Erqi river beach; the other two beaches did not show the incidence of C. hepaticum. Conclusions: The monitoring of C. hepaticum in the Yangtze River beaches should be strengthened to reduce the risk of human C. hepaticum infection.
