Objective To assess the evolution of gastric epithelial dysplasia (GED). Methods We reviewed the history of 239 of patients with gastric dysplasia diagnosed by endoscopic biopsy, and 195 were followed up for 61. 37 months. Results Among 239 cases of dysplasia (261 lesions) , there were 119, with mild dysplasia, 77 with moderate dysplasia, and 43 with severe dysplasia. The gastric dysplasia lesions are mainly in lesser curvature, and its endoscopic appearance mostly is localized erosion. In the follow - up group, regression of dysplasia was demonstrated in 86. 36% , 81. 25% , and 47. 62% of mild, moderate and severe dysplasia respectively. Progression to gastric cancer was detected in 8. 18% , 15. 63% , and 72. 09% of mild, moderate, and severe dysplasia, respectively. The relative risk (RR) of mild, moderate, severe dysplasia was 1. 96, 3. 74, and 17. 25 respectively. Conclusion Carcinomatous evolution of GED increases proportionally with its histological grade. Gastroscopy biopsy follow-up should be held up for all grades of GED, especially, in high grade GED, gastroscopy and biopsy should be taken as soon as possible.

Objective To report the clinical, myopathological and genetic features of a patient with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS)/Leigh syndrome (LS) overlap syndrome who carried m.10158 T>C mutation. Methods The patient′s clinical and imaging materials were collected. An open biopsy of right biceps brachii was performed. DNA samples were prepared from the patient and her mother′s blood. Direct sequencing of the complete mitochondrial genome was performed to detect the mtDNA mutation.Western blotting was used to estimate the content of respiratory complexes in the patient′s muscle. Results The patient was a 40-year-old female. She had seizures and lost consciousness for 9 months. Brain MRI findings consisted of asymmetrical lesions in the cerebral cortex of the frontal and temporal lobes, as well as symmetrical lesions bilaterally in the basal ganglia. Muscle biopsy showed typical ragged red fibers. Direct sequencing of the complete mitochondrial genome from blood and muscle of the patient revealed the T-to-C transition at nucleotide position 10158 in the MT-ND3 gene.The mutation rate was 9.31% and 70.0%, respectively.Western blotting demonstrated that the contents of complexes Ⅰ and Ⅳ were significantly lower in the patient′s muscle mitochondria compared with the normal controls (53.1%±1.2% vs 88.6%±1.7%, t=4.08, P<0.05;57.3%±2.4% vs 80.1%±2.1%, t=3.39,P<0.05).Conclusion We reported a case of MELAS/LS overlap syndrome who carried m.10158 T>C mutation in MT-ND3 gene and DNA test is very important for the diagnosis of the disease.

Abstract: Objective To investigate the fundus arteriosclerosis and its influencing factors in HIV/AIDS patients after long-term highly active antiretroviral therapy (HAART). Methods The clinical basic data and fundus examination data of 203 HIV/AIDS patients before and after HAART in the Fourth People 's Hospital of Nanning from January 2020 to June 2022 were collected to evaluate the occurrence of fundus arteriosclerosis and analyze its influencing factors. Results Of the 203 HIV/AIDS patients, 159 patients developed fundus arteriosclerosis, with an incidence of 78.33%, including 33 patients with grade Ⅰ(20.75%), 87 patients with grade Ⅱ (54.72%), 28 patients with grade Ⅲ(17.61%), and 11 patients (6.92%) with Grade Ⅳ. Before HAART, there was no significant difference in CD4+T lymphocyte count, CD8+T lymphocyte count, viral load, white blood cell count, platelet count, hemoglobin, serum creatinine, blood urea nitrogen, triacylglycerol, total cholesterol, fasting blood glucose, alanine aminotransferase, aspartate aminotransferase and serum total bilirubin between the atherosclerosis group and normal group (P>0.05). After 6 months of HAART, CD8+T lymphocyte count, triacylglycerol and fasting blood glucose in atherosclerosis group were significantly higher than those in normal group (P<0.05). In the stratified comparison of CD4+ and CD8+ lymphocyte counts after 6 months of HAART, the proportion of patients with CD4+ lymphocyte count (CD4+)<200 (cells/μL) in the atherosclerosis group was significantly higher than that in the normal group; the proportion of patients with CD4+ lymphocyte count (CD4+)≥500 (cells/μL) was significantly lower than that in the normal group; the proportion of patients with CD8+ lymphocyte count CD8+≥ 800/μL was significantly higher than that in the normal group (all P<0.05). Binary logistic regression analysis showed that opportunistic infection, HIV course, CD4+T, CD8+T lymphocyte count after HAART and triglyceride were independent risk factors for ocular fundus atherosclerosis in HIV/AIDS patients (all P<0.05). Conclusions The incidence of ocular fundus arteriosclerosis is high in HIV/AIDS patients. More than 4 years of HIV course, combined opportunistic infection, Low CD4+T lymphocyte count after 6 months of HAART, high CD8+T lymphocyte count and high triglyceride level are independent risk factors for ocular fundus arteriosclerosis in HIV/AIDS patients. Fundus screening should be performed before and after HAART in such population, HAART program should be formulated for the risk of cardiovascular disease, and risk management of cardiovascular disease should be strengthened during treatment to improve patient outcomes.

AIMTo investigate the causative role of nitric oxide synthase (NOS) and nitric oxide (NO) in neurotoxicity of beta-amyloid (Abeta) and the pathogenesis of Alzheimer's disease (AD).
METHODSUsing behavioral and neuropathological methods, we observed the effects of Abeta(1-40) injection into hippocampi on rats learning and memory in Y maze and on the neuropathology in hippocampi. The intervention by intraperitoneal administration of aminoguanidine (AG), a selective inducible NOS (iNOS) inhibitor, and 7-nitroindazole (7-NI), a selective neuronal NOS (nNOS) inhibitor, in the neurotoxicity of Abeta(1-40) was studied then.
RESULTSThe capability of acquisition and retrieval in Y maze and local neurons in hippocampus of the rats were impaired significantly after Abeta(1-40) injection. Intraperitoneal administration of AG, but not 7-NI, could prevent the damages caused by Abeta(1-40) injection above-mentioned.
CONCLUSIONiNOS/NO participates in the mechanisms of Abeta-induced neurotoxicity and may play an important role in the pathogenesis of AD.
