The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO2 of S group were significantly higher before CPB time of rewarming than that before SGB (P＜0.05), much higher than corresponding non-blocked side rSO2 before CPB (P＜0.05), and much higher than rSO2 level in group C before CPB and after CPB(P＜0.05). The non-blocked side rSO2 in group S before anesthesia were much lower than basic levels and those in group C (P＜0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO2 compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.
摘要:目的:研究高血压病患者脂蛋白脂肪酶(liportein lipase, LPL)S447X基因多态性与认知功能之间的关系。方法: 对2008年1月至2008年11月在四川大学华西医院医院门诊就诊的原发性高血压患者190例,收集一般资料,采用国际通用的简易智力状况量表测验认知功能,计算认知评分,用聚合酶链反应限制性片段长度多态性(PCRRFLP)技术测定LPL S447X基因多态性。同时测定胆固醇、甘油三酯、空腹血糖、空腹胰岛素及餐后2h血糖、餐后2h胰岛素水平。结果: 高血压病患者认知功能正常组和认知功能障碍组组间LPLS447X基因的基因型和基因频率差异均无统计学意义(Pgt;0.05), SS和SX频率分别为92.6%、7.4%,S和X等位基因频率分别为96.3%和3.7%。结论: LPLS447X 基因多态性可能与高血压认知功能障碍无明显相关性。Abstract: Objective:To study the relationship between liportein lipase(LPL) S447X polymorphism and cognitive function in patients with primary hypertension. Methods:One hundred and ninety hypertensive patients from January 2008 to November 2008 in West China Hospital of Si Chuan University. We collected the general data and applied the Mini Mental State Examination to test the cognitive function and computed score. PCRRELP method was used to analyze the LPL S447X gene polymorphism. Total cholesterol、triglyeride、fasting plasma glucose and postprandial blood sugar、fasting insulin and postprandial plasma insulin were collected. Results:In primary hypertensive patients, both of the genotype frequency and the allele frequency of the LPL S447X polymorphism were not different between the cognitive normal group and the cognitive impaired group (Pgt;0.05). SS genotype was present in 0926 of the population, SX genotype was present in 0.074 of the population. allele frequencies were 0.963 for S allele and 0.037 for X allele. Conclusion:This results suggest S447X polymorphism in LPL with primary hypertension may not be associated with cognitive impairment. And age and postprandial plasma insulin level are the risk factors of hypertensive cognitive impairment.
Hypoxia and other factors are related to cognitive impairment. Hyperbaric oxygen therapy can improve tissue oxygen supply to improve brain hypoxia. Based on the basic principle of hyperbaric oxygen therapy, hyperbaric oxygen has been widely used in recent years for cognitive impairment caused by stroke, brain injury, neurodegenerative disease, neuroinflammatory disease and metabolic encephalopathy. This article will review the basic mechanism of hyperbaric oxygen, and summarize and discuss the improvement of hyperbaric oxygen therapy on cognitive and brain diseases, in order to provide relevant reference for clinical treatment.
Based on literatures on Meta-analysis and randomized controlled trial, drug use and some geriatrics syndromes such as cognitive impairment and depression, in elderly diabetic patients were reviewed. Insulin plus oral hypoglycemic drugs was more rational therapy for insulin resistance and islet dysfunction in type 2 diabetes mellitus. We should pay more attention to cognitive impairment and depression in elderly type 2 diabetic patients.
ObjectiveTo summarize the research progress on the impact of postoperative adjuvant chemotherapy on frailty, cognitive function, and quality of life in older patients with breast cancer.MethodCollected literatures about the impact of postoperative adjuvant chemotherapy on frailty, cognitive function, and quality of life in older patients with breast cancer to make an review.ResultsElderly breast cancer patients were likely to benefit from postoperative adjuvant chemotherapy without undergoing significant impairment of frailty, cognitive function, and quality of life. However, postoperative adjuvant chemotherapy might cause an aggravation of the frailty in patients who was already with it.ConclusionWe should develop personalized treatment plans for elderly breast cancer patients after multidisciplinary assessment.
Objective To systematically review the efficacy and safety of acupuncture for the treatment of tumor-related cognitive dysfunction. Methods The PubMed, The Cochrane Library, EMbase, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies on acupuncture for the treatment of tumor-related cognitive dysfunction from the establishment of the database to February 13th, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4.1 software. Results A total of 16 studies involving 1 361 patients were included. The results of meta-analysis showed that the mini-mental state examination (MD=1.82, 95%CI 1.49 to 2.15, P<0.000 01) and Montreal cognitive assessment (MD=1.56, 95%CI 0.83 to 2.29, P<0.0001) scores of the acupuncture treatment group were superior to those in the control group. Furthermore, the acupuncture treatment group showed a reduced incidence of postoperative cognitive dysfunction (RR=0.50, 95%CI 0.39 to 0.63, P<0.000 01) and decreased levels of interleukin-6 (MD=−10.43, 95%CI −14.91 to −5.95, P<0.000 01), interleukin-1β (MD=−47.14, 95%CI −63.92 to −30.36, P<0.000 01), and tumor necrosis factor-α (MD=−9.13, 95%CI −12.38 to −5.89, P<0.000 01). In contrast, the visual analog scale score of the acupuncture treatment group (MD=−1.26, 95%CI −2.06 to −0.47, P=0.002) was better than that of the control group. No significant difference was found in the level of central nervous system-specific protein (S100β) (MD=−0.06, 95%CI −0.13 to 0.01, P=0.12) between the two groups. Conclusion Acupuncture therapy can improve tumor-related cognitive function in patients. Its curative effect is better than that of non-acupuncture therapy; however, its ability to reduce S100β levels is not significantly different from that of non-acupuncture therapy. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.

ResultsThe curative operation group had significant better seizure free rate, and cognitive statement than medication group. And, the seizure free and cognitive outcome were better in palliative operation group than the medication group. ConclusionsEarly surgical intervention is highly recommended for intractable epilepsy chilelren in order to improve both the seizure and cognitive prognosis.
ObjectiveTo analyze the risk factors of postoperative cognitive dysfunction (POCD) in elderly patients after abdominal surgery. MethodsThe clinical data of 2 286 patients over 60 years old after abdominal surgery were retrospectively analyzed, which were divided into non-POCD group with 2 248 patients and POCD group with 38 patients. The influencing factors of POCD in elderly patients after abdominal surgery, including the age, gender, anesthetic way, the premedication, cormobided with lung or heart disease, diabetes, jaundice, anemia or hypoproteinemia, the duration of surgery, and postoperative analgesia protocols, were analyzed between two groups. ResultsThe age, anesthetic way, cormobided with lung or heart disease, diabetes, jaundice, with or without continuous postoperative effective analgesia, and surgery duration over four hours were relevant with POCD (Plt;0.05), while gender, the premedication, and preexisted anemia or hypoproteinemia were not relevant with that (Pgt;0.05). ConclusionAge over 70 years, general anaesthesia, cormobided with lung or heart disease, diabetes, jaundice, surgery duration over four hours, and incomplete postoperative analgesia are the risk factors of POCD after abdominal surgery.
