Objective To investigate the changes of mitochondrial unfolded protein response (mtUPR) in hippocampus of lithium-pilocarpine induced seizures and the effect of mitochondria-targeted antioxidant. Methods Lithium chloride and pilocarpine were used to elicit status epilepticus in rats, and the rats were further treated with mitochondria-targeted antioxidant Mito-TEMPO. Adult male Wistar rats were randomly divided into control group, PILO group, Mito-TEMPO group and PILO +Mito-TEMPO group. Nissl staining was used to observe the damage of hippocampal neurons, electron transmission microscopy was used to observe the ultrastructure of mitochondria, ROS production of mitochondria was detected by reactive oxygen species fluorescent probe (DCFDA), and mitochondrial membrane potential was detected by Rhoda.mine123 staining. The expressions of mitochondrial heat shock protein HSP60, protease LONP1 and mitochondrial protease CLpP were detected by Western blot. Results (1) Compared with CON group, the ultrastructure of hippocampal neuronal mitochondria in PILO group was seriously damaged, mitochondrial ROS production was increased, and mitochondrial membrane potential was decreased. (2) Compared with the CON group, the expressions of HSP60 , Lonp1 and CLpP in the PILO group were increased. (3) Compared with the PILO group, the damage of mitochondrial ultrastructure was alleviated in the PILO+Mito-TEMPO group, the production of mitochondrial ROS was significantly reduced, and the mitochondrial membrane potential was increased. (4) Compared with the PILO group, the expressions of HSP60, LONP1 and CLpP in the hippocampal neurons of the PILO+Mito-TEMPO group were decreased. Conclusion The mtUPR is significantly activated in hippocampal neurons in epilepsy, and Mito-TEMPO may play a protective role in hippocampal mitochondrial injury in epilepsy regulating mtUPR.

Objective:To observe the gene mutations and clinical phenotypes in patients with Usher syndrome type 2 (USH2) and retinitis pigmentosa (RP).Methods:From August 2018 to January 2019, 4 patients and 11 normal family members from 3 families of USH2 and RP who visited Henan Eye Hospital were enrolled in the study. Detailed medical history was obtained and visual acuity, fundus color photography, OCT, visual field, full field ERG examination were performed. Among the three families, pedigree 1 was diagnosed with USH2, pedigree 2 and pedigree 3 were diagnosed with RP. The peripheral venous blood of patients and their family members were collected, and the whole genomic DNA was extracted. Targeted capture next generation sequencing analysis was performed on these members, and Sanger sequencing and family cosegregation were verified.Results:In the family F1, the proband had symptoms of RP and sensorineural deafness. Sequencing revealed two heterozygous frameshift variants: c.13877-13880 del AGAC (p. Q4626P) in exon 64 and c.798 del T (p. F266L) in exon 5 of USH2A. Both patients of family 2 and 3 showed RP signs without deafness. Two heterozygous variants c.15178T> C (p. S5060 P) in exon 70 and c.6986C> A (p. P2329H) in exon 37, and a pathogenic heterozygous variant c.5836C> T (p. R1946X) in exon 29 of USH2A were identified in family F2. A heterozygous missense variant c.14951C> T (p. P4984L) in exon 68 and a variant c.11156G> A (p. R3719H) in exon 57 of USH2A were found in family F3. The results of conservation analysis showed that the corresponding amino acid sites of USH2A p.Q4626P, p.F266L, p.S5060P, p.P2329H and p.P4984L were highly conserved in many species. Among these 7 pathogenic variants detected, M1-M4 and M6 were novel.Conclusions:Mutation USH2A gene are the main cause of USH2 and non-syndromic RP. Different variants affect protein translation and synthesis, consequently causing different clinical phenotypes.

OBJECTIVETo investigate the changes in red blood cell count in patients with different liver diseases and the correlation between red blood cell count and degree of liver damage.

METHODSThe clinical data of 1427 patients with primary liver cancer, 172 patients with liver cirrhosis, and 185 patients with hepatitis were collected, and the Child-Pugh class was determined for all patients. The differences in red blood cell count between patients with different liver diseases were retrospectively analyzed, and the correlation between red blood cell count and liver function status was investigated. The Mann-Whitney U test, Kruskal-Wallis H test, rank sum test, Spearman rank sum correlation test, and chi-square test were performed for different types of data.

RESULTSRed blood cell count showed significant differences between patients with chronic hepatitis, liver cancer, and liver cirrhosis and was highest in patients with chronic hepatitis and lowest in patients with liver cirrhosis (P < 0.05). In the patients with liver cirrhosis, red blood cell count tended to decrease in patients with a higher Child-Pugh class (P < 0.05).

CONCLUSIONFor patients with liver cirrhosis, red blood cell count can reflect the degree of liver damage, which may contribute to an improved liver function prediction model for these patients.
