Objective To improve the understanding of the characteristics of obstructive sleep apnea-hypopnea syndrome (OSAHS) in the elderly patients, and to improve the diagnosis and treatment level. Methods Monitoring results of polysomnography (PSG) from 110 elderly OSAHS patients were analyzed retrospectively. The general conditions, sleep architecture, apnea and hypopnea events, oxygen reduction as well as possible correlations between various indicators were analyzed using SPSS18.0 statistical software. Results The median rapid eye movement (REM) and non-REM (NREM) sleep time of elderly patients with OSAHS accounted for 2. 17% and 76.73%,respectively. The median arousal index was 45.6 times/h. The longest time of sleep apnea was (51.94±22.06) s, the median of average sleep apnea time was 22.50 s, the longest time of hypopnea was (47.06±12.52) s and the average hypopnca time was (21.50±4.63) s. The median respiratory disturbance index (RDI) of all patients was 21.50, the patients with RDI between 5 and 20 accounted for 46.40%, with RDI between 20 and 40 accounted for 31.80% and with RDI over 40 accounted for 21.8%. The average oxygen saturation accounted for (93.45% ± 2.81%), the lowest oxygen saturation accounted for (76.3%± 10. 5%) and the median oxygen desaturation index was 31.6;times/h. BMI was negatively correlated with lowest oxygen saturation (r=-0. 378, P<0.01) and average oxygen saturation ( r = - 0. 355, P < 0. 01 ), while was positively correlated with oxygen desaturation index (r=0. 338, P<0. 01 ). The lowest oxygen saturation was negatively correlated with the longest time of obstructive apnea (r= -0. 47, P<0. 01 ), the average time of obstructive apnea (r=-0.316, P<0.01), the longest time of hypopnea (r=-0.293, P<0.01) and the average time of hypopnea (r=-0. 277, P<0.01). The median time intervals of oxygen desaturation during supine, left side and right side position were 2.36 min, 11.54 min and 12.45 min,respectively. The median time intervals of oxygen desaturation during left side and right side position were both longer than that of supine position (Z= -6.12 and -7. 10 respectively, both P<0.01).Conclusions Elderly patients with OSAHS manifest obvious disorder of sleep structural and sleep fragmentation. According to RDI, the majority of the patients are classified as mild to moderate in severity. However, elderly patients with OSAHS are severe regarding to hypoxia relatively. The severity of hypoxia is related with BMI and the lasting time of sleep-disordered breathing events, and hypoxia are less severe when sleeping on left side or on right side.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

This article aims to comprehensively review the concept, etiology, classification, classical cortical mapping, assessment, a proposed flowchart for the diagnosis and differential diagnosis, treatment, rehabilitation, mechanisms of development and recovery, prognosis, and influencing factors for post-stroke aphasia(PSA)types in the Chinese language.We emphasize the necessity and significance of neuroimaging assessment of the brain and blood vessels and neuropsychological assessment in the diagnosis and differential diagnosis of PSA in Chinese.We also recommend and encourage the use of the dichotomies of internal vs.external and anterior vs.posterior as a starting point, based on the association of anatomical locations of the brain and blood vessels with brain language areas and language disorders.A classification system of PSA in Chinese developed from this approach in the form of a flowchart is well-suited for guiding the clinical treatment of cerebral stroke.Incorporating the "four elements" , the flowchart enables convenient diagnosis, classification and differential diagnosis of PSA in Chinese and facilitates targeted and personalized rehabilitation planning to benefit the patient.This article introduces the use of memantine, piracetam, donepezil and other drugs for PSA treatment, evaluates clinical trials on memantine conducted in China and abroad and its mechanisms of action for the treatment of PSA, and discusses how rehabilitation therapy achieves therapeutic effects.For the treatment of PSA, clinical research and practice using drugs such as memantine, piracetam and donepezil in combination with non-pharmacotherapy and rehabilitation training should be promoted.

ObjectiveAcute myocardial infarction (AMI) is a highly prevalent and deadly disease globally, with its incidence continuing to rise in recent years. Timely reperfusion therapy is crucial for improving the prognosis of AMI patients. However, myocardial reperfusion can lead to irreversible myocardial ischemia/reperfusion (MI/R) injury, which is associated with adverse cardiovascular outcomes following AMI. Studies have shown that microRNAs (miRNAs) are abnormally expressed during MI/R injury and play an important role in the fate of cardiomyocytes. Effective preventive and therapeutic strategies against MI/R injury remain lacking in clinical practice, necessitating elucidation of the molecular mechanisms underlying MI/R onset and progression. This study investigated the role of microRNA-878 (miR-878) in the regulation of mitochondria-mediated apoptosis in MI/R injury. MethodsThe H9c2 cells were flushed with a gas mixture containing 1% O2, 5% CO2 and 94% N2 for 3 h. Then the cells were incubated in complete culture medium under 5% CO2 and 95% air for 6 h to mimic in vivo hypoxia/reoxygenation (H/R) injury. Cell viability were detected by CCK-8 assay. The concentrations of lactate dehydrogenase (LDH) were then measured.The level of apoptosis was analyzed by flow cytometry. The morphology of mitochondria was analyzed by immunofluorescence and laser confocal microscopy. The levels of mitochondrial reactive oxygen species (mtROS) were detected by immunofluorescence. Dual luciferase reporter gene assay was used to study the binding site of miR-878 and Pim1. RNA immunoprecipitation (RIP) assay was used to verify the binding relationship between miR-878 and Pim1. The gene expression levels were detected by real-time fluorescent quantitative PCR (RT-qPCR) and Western blot. ResultsThe study found that compared with the control group, the expression of miR-878 in H/R-treated H9c2 cells was significantly increased ((1.00±0.25) vs (9.70±2.63), P<0.01). In H/R-induced cells, transfection of miR-878 inhibitor significantly increased cell viability ((46.67±3.00) vs (74.62±4.08), P<0.000 1), and decreased LDH release ((358.58±41.71) vs (179.09±15.59), P<0.000 1) and cell apoptosis rate ((43.41±0.72) vs (27.42±4.48), P<0.01). At the same time, downregulation of miR-878 expression significantly inhibited DRP1-mediated mitochondrial overdivision and mtROS production ((6.60±0.57) vs (4.32±0.91), P<0.000 1). The mechanism study showed that miR-878 could target and bind Pim1 and inhibit the expression level of Pim1 ((1.00±0.13) vs (0.38±0.03), P<0.01). Rescue experiments confirmed that down-regulation of Pim1 expression significantly reversed the anti-injury effect of miR-878 inhibitor in H9c2 cells (P<0.01), promoted mitochondrial overdivision and mtROS production ((1.00±0.12) vs (2.41±0.12), P<0.01), and decreased the expression level of p-DRP1 ((1.00±0.15) vs (0.59±0.06), P<0.05). ConclusionThe present study demonstrates that miR-878 expression is upregulated in H9c2 cardiomyocytes subjected to H/R injury. Inhibition of miR-878 expression alleviates H/R-induced cardiomyocyte damage. Notably, downregulation of miR-878 significantly inhibits DRP1-mediated mitochondrial fission and mitigates mtROS production. Mechanistically, miR-878 targets and binds to the 3'-UTR of the Pim1 gene, thereby suppressing Pim1 protein expression. Collectively, these findings suggest that under H/R conditions, miR-878 promotes excessive mitochondrial fragmentation through DRP1 activation by targeting Pim1, ultimately contributing to cardiomyocyte injury. Modulation of the miR-878/Pim1 axis may represent a potential therapeutic strategy for mitigating MI/R-induced cardiac damage.

OBJECTIVETo identify the risk factors of early post-TIPS hepatic encephalopathy (HE) and the long-time survival of patients with or without early post-TIPS HE.
METHODSConsecutive cirrhotic patients who underwent TIPS for variceal rebleeding or refractory ascites in our center from January 2003 to December 2008 were included in this study. More than 60 clinical characteristics were enrolled in univariate analysis and logistic regression analysis to define the risk factors of HE in 3 months after TIPS procedure (early post-TIPS HE). The long-time survival of patients with or without early post-TIPS HE was compared by Cox regression with several covariates.
RESULTSAccording to our inclusion criteria, 190 patients were included. The median follow-up was 30.5 months. Lower serum concentration of fibrinogen and higher Child-Pugh score were the independent risk factors for suffering early post-TIPS HE. Patients without early post-TIPS HE after TIPS showed better prognosis than those with early post-TIPS HE after TIPS (P = 0.044).
CONCLUSIONPatients with lower serum fibrinogen and higher Child-Pugh score before TIPS might be more probably attacked by early post-TIPS HE which indicated worse long-term survival.
