4.Progress in Diagnosing Mitochondrial Myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like Episodes.
Chinese Medical Journal 2015;128(13):1820-1825
OBJECTIVEMitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a progressive, multisystem affected mitochondrial disease associated with a number of disease-related defective genes. MELAS has unpredictable presentations and clinical course, and it can be commonly misdiagnosed as encephalitis, cerebral infarction, or brain neoplasms. This review aimed to update the diagnosis progress in MELAS, which may provide better understanding of the disease nature and help make the right diagnosis as well.
DATA SOURCESThe data used in this review came from published peer review articles from October 1984 to October 2014, which were obtained from PubMed. The search term is "MELAS".
STUDY SELECTIONInformation selected from those reported studies is mainly based on the progress on clinical features, blood biochemistry, neuroimaging, muscle biopsy, and genetics in diagnosing MELAS.
RESULTSMELAS has a wide heterogeneity in genetics and clinical manifestations. The relationship between mutations and phenotypes remains unclear. Advanced serial functional magnetic resonance imaging (MRI) can provide directional information on this disease. Muscle biopsy has meaningful value in diagnosing MELAS, which shows the presence of ragged red fibers and mosaic appearance of cytochrome oxidase negative fibers. Genetic studies have reported that approximately 80% of MELAS cases are caused by the mutation m.3243A>G of the mitochondrial transfer RNA (Leu (UUR)) gene (MT-TL1).
CONCLUSIONSMELAS involves multiple systems with variable clinical symptoms and recurrent episodes. The prognosis of MELAS patients depends on timely diagnosis. Therefore, overall diagnosis of MELAS should be based on the maternal inheritance family history, clinical manifestation, and findings from serial MRI, muscle biopsy, and genetics.

The clinical data and routine biochemical parameters of 64 maintenance hemodialysis (MHD)patients and 20 controls were analyzed in the study.Serum cystatin C levels were detected by latex particle enhalice inununo-turbidimetry:and the cardial structure and function were assessed by echocardiography.As MHD time extended,the levels of semm cystatin C increased gradually,accompanied with high incidence of left ventricular hypertrophy(LVH).The LVH-positive patients had higher systolic blood pressure and left veHtricular mass index,and had higher serum cystatin C than tllose in LVH-negative patients.The serum cystatin C levels were positively correlated with left yentricular mass index(r=0.633,P<0.01)and systolic blood pressure(r:0.397,P<0.01).The results suggest that serum cystatin levels may be an influencing factor for long-term cardiacvascular complication in MHD patients.

Objective To investigate the changes in femoral gene expression profiles in C57BL/6 mice fed high-fat diet (HFD) via clustering analysis of DNA microarray.Method Sixteen male C57BL/6 mice (4w old) were randomly assigned to two groups,8 in each,after 4-d ordinary diet for adaptation.The control group was fed with an ordinary diet,and the HFD group with HFD(19.5% lard).All mice were sacrificed at the end of 12w and the femoral gene expression was detected by oligonucleotide microarray analysis with Affymetrix Gene Chip Mouse U430A.DAVID,an online tool,was used for clustering analysis on femoral gene expression.Results Longtime administration of HFD caused femoral gene expressed differences related to cation ion channel,transcription regulation and signal transduction,bone mineralization,phosphate metabolic process regulation,and collagen synthesis.Conclusion Longtime intake of HFD will change the expression of numerous bone metabolism-related genes in bone of mice,and then inhibit bone formation.

Objective To explore the effect of electroacupuncture at Hegu (LI 4) on the expressions of P2X2 and P2X3 receptors in experimental pulpalgia rats.Method Forty-two male SD rats were randomized into a normal group (group N), a control group (group C), a pulpalgia model group (group M), an antagonist group (group A), an electroacupuncture group (group E), and an antagonist+electroacupuncture group (group AE), 7 rats in each group. Group N didn’t receive any interventions; group C received injection of normal saline into pulp cavity of the same dose as the injection in group M, and the cavity was then blocked by dental fillings 5-6 min later; in group M, maxillary first and second molar teeth were drilled (drill bit of 1 mm in diameter) to expose pulp and lipopolysaccharide (LPS) solution 5μg/μL was injected into the holes (1~3μL for each hole), and the holes were then covered by dental fillings 5-6 min later; group A received the same modeling method as that in group M, but A-317491 was injected together with LPS (0.5 mg/kg); group E received electroacupuncture at bilateral Hegu (LI 4) with needles retained for 30 min, once a day, totally for 3 times; group AE received the same electroacupuncture intervention after receiving the same treatments as that in group A. The rats’ behaviors and weight were observed for 30 min after intervention each day. The rats were sacrificed on the 4th day, and the mRNA expressions of P2X2 and P2X3 receptors andβ-actin in trigeminal ganglion were detected by using RT-PCR. The mRNA expressions were then compared among the groups.Result The behavioral changes in group M, E, and AE were more significant than that in group C and N (P<0.01); the behavioral changes in group A, E, and AE were less significant than that in group M (P<0.01). The weight in group C was significantly lower than that in group N (P<0.01); the weights in group M, A, E and AE were significantly lower than that in group C and N (P<0.01); the weights in group E and AE were significantly higher than that in group M and A (P<0.01,P<0.05); the weight in group A was slightly higher than that in group M (P<0.05); the weights in group AE was significantly higher than that in group E (P<0.01). The mRNA expressions of P2X2 receptor in group M, A, and AE were significantly higher than that in group N and C (P<0.01); the mRNA expressions of P2X2 receptor in group A, E, and AE were lower than that in group M (P<0.05); the mRNA expression of P2X2 receptor in group A was lower than that in group E (P<0.05); the mRNA expression of P2X2 receptor in group E was higher than that in group AE (P<0.05). The mRNA expressions of P2X3 receptor in group M, A, and E were significantly higher than that in group C (P<0.05) and group N (P<0.01); the mRNA expressions of P2X3 receptor in group A, E, and AE were significantly lower than that in group M (P<0.01); the mRNA expression of P2X3 receptor in group AE was markedly lower than that in group E (P<0.01).Conclusion The expressions of P2X2 and P2X3 receptors in trigeminal ganglion were increased in LPS-induced pulpalgia rats. Electroacupuncture at Hegu (LI 4) and injection of A-317491 both can down-regulate the mRNA expressions of P2X2 and P2X3 receptors, which is plausibly the action mechanism of electroacupuncture at Hegu (LI 4) in analgesia.

AIM: To evaluate the changes in central corneal thickness (CCF) caused by mydriasis with Mydrin-P.METHODS: A total of 106 eyes of 53 patients with refractive errors were studied. Each eye had instillation of Mydrin-P to obtain mydriasis. CCT was examined before and after mydriasis using ultrasonic pachymeter.RESULTS: CCT increased significantly after mydriasis with Mydrin-P.CONCLUSION: Mydrin-P can affect the measurement of CCT.
