  • Acupuncture for the treatment of tumor-related cognitive dysfunction: a meta-analysis

    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.

  • The levels of monocyte chemotactic protein 1 and serum amyloid A protein in peripheral blood and their correlation with cognitive function in COPD patients with or without hypoxemia

    Objective To explore the correlation of protein and mRNA levels of monocyte chemotactic protein-1 (MCP-1) and serum amyloid A protein (SAA) with cognitive function in chronic obstructive pulmonary disease (COPD) patients with or without hypoxemia, in order to identify the serum indexes of early cognitive impairment in patients with COPD, and investigate the effect of hypoxemia on cognitive impairment. Methods Sixty-two COPD patients admitted in the respiratory department of Affiliated Hospital of North China University of Science and Technology from January 2013 to January 2017 were included in the study. The COPD patients were divided into a hypoxemia group (25 cases) and a non-hypoxemia group (37 cases) according to blood gas analysis. Meanwhile 30 healthy subjects were recruited as control. ELISA was used to measure the concentration of serum MCP-1 and SAA in all subjects, and RT-PCR was used to detect the mRNA expression of MCP-1 and SAA in peripheral blood mononuclear cells. Montreal cognitive assessment scale (MoCA scale) was used to determine cognitive function. The expression levels of MCP-1 and SAA were compared between three groups, and the correlations with cognitive dysfunction were analyzed. Results The expression levels of serum MCP-1 and SAA had the same trend as those of MCP-1 mRNA and SAA mRNA in peripheral blood in the COPD patients. The protein and mRNA levels of MCP-1 and SAA were higher than those in the healthy control group (all P<0.05). The COPD hypoxemia group and the COPD non-hypoxemia group were lower than the control group in MoCA score, and the MoCA score of the COPD hypoxemia group decreased more obviously (allP<0.05). The protein and mRNA levels of SAA and MCP-1 were negatively correlated with MoCA score (allP<0.05). Conclusion The protein and mRNA levels of MCP-1 and SAA in peripheral blood increase in COPD patients, and hypoxemia may be involved in cognitive dysfunction in COPD patients.

  • Analysis of Influencing Factors of Postoperative Cognitive Dysfunction Following Laparoscopic Surgery in Elderly Patients

    ObjectiveTo investigate influencing factors of postoperative cognitive dysfunction (POCD) in elderly patients underwent laparoscopic surgery. MethodsThe elderly patients underwent laparoscopic surgery were collected in the Daye City People's Hospital and Yangxin County People's Hospital from September 14, 2014 to January 1, 2016 and the Traditional Chinese Medicine Hospital of Daye City from June 19, 2014 to January 1, 2016. Factors included in the registration of patients in general and a variety of influencing factors during perioperative period were recorded. The independent factors associated with POCD were analyzed by multivariate logistic regression analysis. ResultsThree hundred and seventy-eight elderly patients underwent laparoscopic surgery were included according to the inclusion and exclusion criteria, of which 43 patients with POCD and 335 patients without POCD within 3 days after laparoscopic surgery. The baseline data had no significant differences between the patients with POCD and without POCD. The cerebral infarction, preoperative fear, preemptive analgesia, use of dexmedetomidine before laparoscopic surgery, general anesthesia combined with epidural anesthesia, operation time, low SpO2 during anesthesia induction, PaCO2 after pneumoperitoneum, postoperative patient controlled epidural analgesia (PCEA), postoperative VAS score on day 3 were associated with the POCD (P < 0.05). The results of logistic regression analysis showed that the preemptive analgesia, use of dexmedetomidine before laparoscopic surgery, general anesthesia combined with epidural anesthesia, and postoperative PCEA were the independent protective factors of the POCD (P < 0.05). The operation time and PaCO2 after pneumoperitoneum were the independent risk factors of the POCD (P < 0.05). ConclusionFor elderly patients underwent laparoscopic surgery, clinicians should be alert to occurrence of POCD according to the influence factors of it, and timely screen relevant scale so as to early diagnose and early intervent and effectively delay progress of patient's POCD.

  • Analysis of incidence and risk factors of postoperative delirium in elderly patients undergoing major orthopedic surgery

    Objective To investigate the prevalence of postoperative delirium (POD) in elderly patients undergoing major orthopedic surgery and analyze its influencing factors, so as to provide evidence for early screening and intervention of POD. Methods The medical records of elderly patients undergoing major orthopedic surgery in the Department of Orthopaedics of the First Medical Center, Chinese PLA General Hospital between January 2021 and December 2022 were retrospectively collected. The included patients were divided into POD group and non-POD group. The patients’ demographic characteristics, medical history, laboratory indicators, perioperative medication, intraoperative and postoperative indicators were collected to analyze the risk factors affecting POD. Results A total of 455 elderly patients were included. Among them, there were 75 cases in the POD group and 380 cases in the non-POD group. The incidence of POD was 16.5% (75/455). There were statistically significant differences in age, body mass index, number of combined underlying diseases≥3, albumin<35 g/L, American Society of Anesthesiologists (ASA) classification, intraoperative blood loss≥200 mL, intraoperative blood transfusion, postoperative Visual Analogue Scale (VAS) score, indwelling catheters, admission to intensive care unit (ICU), and length of ICU stay between the two groups (P<0.05). The results of logistic regression analysis showed that age≥79 years, number of combined underlying diseases≥3, albumin<35 g/L, intraoperative blood loss≥200 mL, ASA grade≥Ⅲ, postoperative VAS score, and postoperative admission to ICU (P<0.05) were independent influencing factors for POD occurrence in elderly patients undergoing major orthopedic surgery. Conclusions POD is one of the common postoperative complications in elderly patients undergoing major orthopedic surgery. Age≥79 years, number of combined underlying diseases≥3, albumin<35 g/L, intraoperative blood loss≥200 mL, ASA grade≥Ⅲ, postoperative VAS score, and postoperative admission to ICU are independent risk factors for POD in elderly patients undergoing major orthopedic surgery. Clinical staff should evaluate and screen these factors early and take preventive measures to reduce the incidence of POD.
