ABSTRACT

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

ABSTRACT

ObjectiveTo explore the clinical efficacy and safety of Fuzheng Huaji Longbi decoction in treating benign prostatic hyperplasia (BPH) in the patients with the syndrome of healthy Qi deficiency and blood stasis. MethodA total of 94 BPH patients were randomized into control and observation groups, with 47 patients in each group. The control group was treated with doxazosin mesylate sustained-release tablets, and the observation group with Fuzheng Huaji Longbi decoction on the basis of the therapy in the control group. After eight weeks, the international prostate symptom score (IPSS), quality of life (QOL) score, residual urine volume (RUV), maximum urinary flow rate (Qmax), TCM syndrome score, TCM symptom score, electrocardiogram, and liver and kidney function were determined to evaluate the clinical efficacy and safety of the two groups. ResultAfter 8 weeks of treatment, the total response rate in the control group was 63.64% (28/44), which was lower than that (84.44%, 38/45) in the observation group (χ2=5.026, P<0.05). The clinical efficacy in the observation group was higher than that in the control group (Z=-2.17, P=0.030). The treatment in both groups decreased the IPSS, QOL score, RUV, and TCM syndrome scores and increased the Qmax (P<0.05). Moreover, the observation group had lower IPSS, QOL score, RUV, and TCM syndrome score (P<0.05) and higher Qmax than the control group after treatment (P<0.05). The treatment in the observation group decreased all the TCM symptom scores (P<0.05), while that in the control group only decreased the frequency of urination at night and the scores of dysuria, weak urine stream, and post-urinary drainage (P<0.05). After treatment, the observation group had lower frequency of urination at night and lower scores of mental fatigue, cold limbs, lower abdominal discomfort, and loose stool than the control group (P<0.05). No adverse events associated with the administration of Fuzheng Huaji Longbi decoction were observed during the treatment period. ConclusionFuzheng Huaji Longbi decoction is effective in treating BPH in the patients with the syndrome of healthy qi deficiency and blood stasis. It can relieve the clinical symptoms and improve the quality of life, being a safe and reliable choice for clinical application.

ABSTRACT

@#Objective To summarize and analyze the clinical diagnosis, surgical treatment and prognosis of multiple pulmonary nodules (MPNs). Methods The clinical data of lung cancer patients who received surgical treatment in our hospital from 2018 to 2020 were collected. The short-term efficacy of surgical treatment for MPNs was analyzed. Results A total of 97 patients were enrolled, including 30 males and 67 females with an average age of 56.1±10.0 years at onset ill. There were 62 patients with double lesions, 22 patients with three lesions, 4 patients with four lesions, and 9 patients with more than four lesions. A total of 213 lesions were surgically treated, including 88 pure ground-glass nodules, 81 partially solid nodules, and 7 solid nodules. There were 87 simultaneous surgeries and 10 staged surgeries, with an average operation interval of 5.2 months. The pathological combination type included adenocarcinoma-adenocarcinoma in 96 (99.0%) patients, squamous cell carcinoma-squamous cell carcinoma in 1 (1.0%) patient, and no lymph node metastasis was found. The 2-year disease-free survival (DFS) rate was 92.1%, and the overall survival (OS) rate was 100.0%. Univariate analysis showed that high-risk lesion size>2 cm (P=0.316), residual lesions (P=0.782) and pathological combination type (P=0.913) had statistical effect on the 2-year DFS rate. Conclusion MPNs are mainly diagnosed with multiple primary lung cancers, and the pathological combination is mostly adenocarcinoma-adenocarcinoma combination. Imaging examination is of great help to the surgical approach selection, diagnosis and differential diagnosis of MPNs. During the operation, maximal preservation of lung function and complete resection of high-risk nodules should be taken as the principle, and the prognosis is satisfactory.

ABSTRACT

ObjectiveTo systematically review the intervention effect of cognitively engaging physical activity (CEPA) on executive function of children and adolescents. MethodsLiteratures in Chinese and English were retrieved from databases of Web of Science, PubMed, Medline, EBSCO and CNKI, from the establishment to November 30th, 2023. According to the inclusion and exclusion criteria, the literatures that met the requirements were screened, and their quality was evaluated and systematically reviewed. ResultsA total of 15 literatures were included, published between 2014 and 2023, from eight countries, involving 1 806 subjects aged four to 16 years. The average score of PEDro scale was 6.6. The intensity of the CEPA intervention ranged from 64% to 93% HRmax, the duration of a single session ranged from ten to 60 minutes, and the frequency of the intervention was two to five sessions a week, for four to 24 weeks. Specific forms of CEPA included football, basketball and floorball combined with cognitive tasks; running, jumping, squatting, sitting, spinning and balancing combined with cognitive tasks; and exergaming combined with cognitive tasks. Eleven researches showed positive effects of CEPA intervention on at least one component of executive function. However, six of the seven researches involving working memory failed to verify the positive effects. Twelve researches compared the intervention effects of CEPA and rutine exercise or regular physical education classes, and nine researches found that CEPA was more effective on executive function. ConclusionThe CEPA is effective on the executive function of children and adolescents, specifically on cognitive flexibility; it shows inconsistent effects on inhibitory control, and its effect on working memory has not been verified. The intervention types of CEPA are divided into ball games combined with cognitive tasks, basic motor skills training combined with cognitive tasks, and exergaming combined with cognitive tasks.

ABSTRACT

Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

ABSTRACT

By consulting the ancient and moderm literature, this paper makes a textual research on the name, origin, quality evaluation, harvesting and processing of Olibanum, so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research, the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu(《名医别录》), until Ruxiang had been used as the correct name since Bencao Shiyi(《本草拾遗》) in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia, while the modern producing areas are Somalia, Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark, which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow, granular, translucent, no impurities such as sand and bark, sticky powder and aromatic smell. There were many processing methods in ancient times, including cleansing(water flying, removing impurities), grinding(wine grinding, rush grinding), frying(stir-frying, rush frying, wine frying), degreasing, vinegar processing, decoction. In modern times, the main processing methods are simplified to cleansing, stir-frying and vinegar processing. Nowadays, the commonly used specifications include raw, fried and vinegar-processed products. Among the three specifications, raw products is the Olibanum after cleansing, fried products is a kind of Olibanum processed by frying method, vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results, it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum, processing method should be carried out in accordance with the processing requirements of the formulas, otherwise used the raw products if the formulas without clear processing requirements.

ABSTRACT

The aim of this study was to investigate the role and mechanism of terpinen-4-ol (T4O) on high glucose (HG) -induced calcification in vascular smooth muscle cell (VSMC). To investigate the role of T4O on HG-induced calcium deposition, osteogenic phenotypic transformation and mitochondrial dynamics in VSMC, Mdivi-1, a mitochondrial dynamin-related protein 1 (Drp-1) inhibitor, was used to analyze the correlation between mitochondrial dynamics and VSMC calcification and the role of T4O. Alizarin red S staining was used to observe calcium salt deposition and flow cytometry to detect intracellular Ca2+ content; Western blot and immunofluorescence were used to detect the expression of phenotypic switching-related markers α-smooth muscle actin (α-SMA), bone morphogenetic protein 2 (BMP2) and Runt related transcription factor 2 (Runx2), and mitochondrial dynamics-related markers mitofusin 1 (MFN1), mitofusin 2 (MFN2) and Drp-1. The results showed that low and high doses of T4O could inhibit HG-induced down-regulation of α-SMA, MFN1 and MFN2 expression levels, and up-regulation of BMP2, Runx2 and Drp-1 expression levels, reduce intracellular Ca2+ content and calcium salt deposition, and effectively inhibit HG-induced VSMC calcification and mitochondrial dynamics disorders. The T4O group, Mdivi-1 group and T4O+Mdivi-1 group were able to up-regulate the expression levels of HG-induced α-SMA, MFN1 and MFN2, down-regulate the protein expression levels of BMP2, Runx2 and Drp-1, and inhibit calcium salt deposition, and there was no significant difference between the above indexes in the T4O and T4O+Mdivi-1 groups. The above findings suggest that T4O can inhibit the expression level of Drp-1, regulate the disturbance of mitochondrial dynamics, and suppress HG-induced VSMC calcification.

ABSTRACT

ObjectiveTo investigate the effect of transcutaneous auricular vagus nerve stimulation (taVNS) combined with robot-assisted therapy on upper limb function of subacute stroke patients. MethodsFrom March, 2022 to March, 2023, 60 subacute stroke patients from Dushu Lake Hospital and the First People's Hospital of Kunshan were randomly divided into control group (n = 20), robot group (n = 20) and combined group (n = 20). All the groups received conventional treatments including medication, physical therapy and occupational therapy; the robot group received sham taVNS combined with hand robot-assisted therapy; while the combined group received taVNS combined with hand robot-assisted therapy, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and hand part, the root mean square (RMS) electromyography of the extensor carpi radialis and extensor digitorum muscles during contraction, and the latency and amplitude of transcranial magnetic stimulation motor-evoked potential (TMS-MEP) before and after treatment. ResultsAfter treatment, the scores of FMA-UE and hand part, RMS of the extensor carpi radialis and extensor digitorum muscles, and latency and amplitude of TMS-MEP improved in all the groups (t > 2.099, P < 0.05); and they were the best in all indicators in the combined group (F > 9.106, P < 0.001). ConclusiontaVNS combined with robot-assisted therapy can promote central nervous system remodeling and further improve upper limb function in stroke patients.

ABSTRACT

Objective:To compare the cost-effectiveness of hospitalized Chinese patients undergoing nucleic acid screening strategies for hepatitis B and hepatitis C, immunological screening strategy, and no screening strategy under different willingness to pay (WTP). The results might aid to decision-making for the optimal strategy.Methods:In this study, nucleic acid screening, immunological screening and no screening were used as screening strategies, and China′s GDP in 2021 (80 976 yuan) was used as the threshold of WTP to construct a Markov model. After introducing parameters related to the diagnosis and treatment of hepatitis B and C in inpatients, a cohort population of 100 000 inpatients was simulated by TreeAge Pro 2021 software, the total cost, total health effects, incremental cost-effectiveness ratio and average cost-effectiveness ratio of different screening strategies were calculated, and cost-effectiveness analysis was conducted. Univariate and probabilistic sensitivity analysis were used to assess the impact of parameter uncertainty on the final results.Results:Compared with the non-screening strategy, the incremental total cost of the hepatitis B immunological screening strategy for cohort patients was 11 049 536 yuan, and the incremental cost-effectiveness ratio was 24 762 yuan/quality-adjusted life years (QALY), while the total incremental cost of nucleic acid screening was 19 208 059 yuan, and the incremental cost-effectiveness ratio was 29 873 yuan/QALY; the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 834 yuan/QALY. Compared with the non-screening strategy, the incremental cost-effectiveness ratio of hepatitis C immunological screening strategy was 5 731 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening strategy was 8 722 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 591 yuan/QALY. The results of probabilistic sensitivity analysis showed that when the cost of nucleic acid testing exceeded 214.53 yuan, it was not cost-effective to perform hepatitis B nucleic acid screening under the WTP as 1 fold GDP. When the cost of nucleic acid testing exceeded 132.18 yuan, it was not cost-effective to conduct hepatitis C screening under the WTP as 1 fold GDP.Conclusions:Nucleic acid screening strategy can achieve more cost-effectiveness and is worthy of vigorous promotion. Compared with no screening, both the nucleic acid and immunological screening strategies are cost-effective, and hepatitis nucleic acid screening is the optimal strategy for hospitalized patients.

ABSTRACT

Objective:This multi-centre study was conducted to assess the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease.Methods:From July 2021 to December 2021, plasma samples of patients admitted to 10 hospitals were collected for screening preoperative/pre-transfusion blood transmitted disease. Nucleic acid detection technology was used to detect hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA and human immunodeficiency virus (HIV)(1+2) RNA, and the results were compared with the immuno-serological methods. χ 2 test and Kappa test were used to analyze the efficacy of these two methods. Results:A total of 8 655 valid specimens were collected from 10 hospitals. There was a statistically significant difference in the positive detection rate of HCV between the two methods ( P<0.001). There was no significant difference in the positive detection rate of HBV and HIV assessed by the two methods ( P>0.05), but the number of positive cases detected by HBV DNA and HIV RNA (218 and 4 cases) was significantly higher than the corresponding serological results (216 and 2 cases). At the same time, there were HBV, HCV and HIV immuno-serological omissions by the immuno-serological methods, among which 28 cases were HBsAg negative and HBV DNA positive, 2 cases were HCV antibody negative and HCV RNA positive, and 2 cases were HIV antigen/antibody negative and HIV RNA positive. In addition, in the 66 samples with inconsistent results from the two detection methods, 83.3% (55/66), 68.2% (45/66), 63.6% (42/66) and 62.1% (41/66) of patients aged was>45 years, tumor, surgery and male, respectively. Conclusions:Compared with immuno-serological tests, nucleic acid tests have the advantage in terms of sensitivity on detecting HBV, HCV and HIV infection and could reduce missed detection. The risk of transmission can be reduced by adding HBV, HCV, and HIV nucleic acid tests to preoperative/pre-transfusion immuno-serological tests screening for patients over 45 years of age and tumor patients.

ABSTRACT

Objective:To explore clinical value of nucleic acid detection for hepatitis B virus (HBV) screening in hospitalized patients.Methods:This cross-sectional study collected and analyzed plasma samples from patients admitted to 10 domestic medical institutions from July 2021 to December 2021. Serological immunoassay and nucleic acid screening were used to simultaneously detect hepatitis B markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e Antigen (HBeAg), hepatitis B e antibody (HBeAb), hepatitis B core antibody (HBcAb),and HBV DNA. Statistical analysis was performed on the serology, nucleic acid test results and clinical information of the patients.Results:Of the 8 655 collected samples, HBsAg was positive in 216 (2.50%) samples,HBV DNA was positive in 238 (2.75%) samples ( P>0.05); 210 (2.43%) samples were positive for both HBsAg and HBV DNA, 28 (0.32%) were HBsAg negative and HBV DNA positive, 6 cases (0.07%) were HBsAg positive and HBV DNA negative. Conclusion:These results indicate that the HBV DNA testing is equally effective as hepatitis B virus serological detection for hepatitis B virus screening in hospitalized patients.

ABSTRACT

Objective:To investigate the risk factors of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients in plain-sand areas and loess hilly areas of Gansu province.Methods:A total of 1 599 T2DM patients who participated in chronic disease and risk factors monitoring and basic public health service management were selected by multi-stage stratified random sampling method in the sandy plain areas and loess hilly areas of Gansu province. Questionnaire survey, physical measurement and laboratory tests were performed. Multivariate binary logistic model was used to analyze the influencing factors.Results:The prevalence of DKD was 22.1% (174/787) among T2DM patients in the sandy plain areas and 19.1%(155/812) in the loess hilly area, respectively. Hypertension ( OR=3.022), hyperuricemia ( OR=2.114) and HbA1c≥7%( OR=2.231) were the risk factors for DKD in the plain-sand areas, and the risk of DKD increased with age. In the loess hilly areas, female sex ( OR=0.379) was the protective factor for DKD; while duration of disease≥10 years ( OR=2.476), hyperuricemia ( OR=1.907), HbA1c≥7% ( OR=1.927) were the risk factors for DKD; and the risk of DKD increased with the increase of age, and decreased with the increase of per capita monthly income. Conclusions:The prevalence of DKD and its influencing factors are different between sandy plain areas and loess hilly areas in Gansu province. The prevention and treatment of hypertension should be given more attention in sandy plain areas. In addition, the screening of DKD should be conducted among T2DM patients, particularly for those with old age, hyperuricemia and HbA1c≥7% in both areas of the province.

ABSTRACT

A 14-year girl was admitted with akinesia and difficulty walking due to gait instability after two oral doses of compound diphenoxylate (lomotil). When she was 18-month old, drowsiness and inability to walk were observed after taking lomotil, the symptoms were relieved by taking B vitamins for treatment. The laboratory tests showed the increased blood branched chain amino acid levels; gene detection indicated that the child had compound heterozygous variations of c.745G>A(p.G249S) and c.485-1G>C in the BCKDHA gene. The girl was finally diagnosed as maple syrup urine disease. The domestic and foreign literature was searched, and 11 child cases of maple syrup urine disease with onset of unsteadiness and ataxia were reported, none of whom was associated with oral administration of compound diphenoxylate.

ABSTRACT

Objective:To evaluate the role of nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway in edaravone-induced attenuation of long-term cognitive impairment caused by long-time sedation with propofol in the neonatal rats.Methods:Eighty SPF healthy newborn Sprague-Dawley rats of both sexes, aged 7 days, weighing 15-20 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), propofol group (group P), edaravone+ propofol group (group EP) and Nrf2 inhibitor ML385+ edaravone+ propofol group (group MEP). Propofol 75 mg/kg was intraperitoneally injected once a day for 7 consecutive days in P group, EP group and MEP group, respectively, while the equal volume of medium/long chain fat emulsion injection was intraperitoneally injected in C group. Edaravone 3 mg/kg was intraperitoneally injected at 30 min before each propofol injection in EP and MEP groups, and ML385 15 mg/kg was intraperitoneally injected simultaneously in group MEP. The spontaneous activity was evaluated by the open field test on day 29 after birth, and the cognitive function was assessed by Morris water maze test on days 30-34 after birth. The rats were sacrificed after the end of water maze test, and brains were removed and hippocampal tissues were obtained for determination of reactive oxygen species (ROS) levels (by flow cytometry), superoxide dismutase (SOD) and malondialdehyde (MDA) levels (by enzyme-linked immunosorbent assay) and expression of Nrf2 and HO-1 (by Western blot) and for microscopic examination of the pathological changes in the hippocampal CA1 area (using HE staining). Results:There was no significant difference in the speed, distance and time of stay at the center of the open field among the four groups ( P>0.05). Compared with C group, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was reduced, the levels of MDA and ROS were increased, the activity of SOD was decreased, the expression of Nrf2 and HO-1 was down-regulated ( P<0.05), and the pathological injury was observed in the hippocampal CA1 region in group P. Compared with P group, the escape latency was significantly shortened, the number of crossing the original platform quadrant was increased, the levels of MDA and ROS in the hippocampus were decreased, the activity of SOD was increased, the expression of Nrf2 and HO-1 was up-regulated ( P<0.05), and the pathological injury in the hippocampal CA1 region was significantly alleviated in EP group. Compared with EP group, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was reduced, the levels of MDA and ROS were increased, the activity of SOD was decreased, the expression of Nrf2 and HO-1 was down-regulated ( P<0.05), and the pathological injury was aggravated in the hippocampal CA1 region in MEP group. Conclusions:The mechanism by which edaravone attenuates long-term cognitive impairment caused by long-time sedation with propofol is related to activation of Nrf2/HO-1 signaling pathway and inhibition of oxidative stress in the neonatal rats.

ABSTRACT

Objective:To evaluate the role of Toll-like receptor 4 (TLR4)/nuclear transcription factor κB (NF-κB) signaling pathway in long-term cognitive impairment induced by multiple exposures to sevoflurane anesthesia in neonatal rats.Methods:Seventy-five SPF healthy newborn Sprague-Dawley rats of either sex, aged 6 days, weighing 12-20 g, were divided into 3 groups ( n=25 each) using a random number table method: control group (group C), multiple exposures to sevoflurane anesthesia group (group S) and TLR4 inhibitor plus multiple exposures to sevoflurane anesthesia group (group I+ S). The rats in group S and group I inhaled 3% sevoflurane for 2 h at 6, 7 and 8 days after birth. TLR4 inhibitor TAK-242 10 mg/kg was intraperitoneally injected before each exposure to sevoflurane in group I, and the equal volume of normal saline was given instead in the other two groups. The spontaneous activity was evaluated by open field test on day 29 after birth, and the cognitive function was assessed by Morris water maze test on days 30-34 after birth. After the behavioral test, the blood samples from the abdominal aorta were collected, and then the rats were sacrificed under deep anesthesia to isolate the hippocampal tissues for measurement of the levels of S100β and neuron-specific enolase (NSE) in serum and hippocampal interleukin-1β (IL-1β), IL-6 and tumor necrosis factor α (TNF-α) (by enzyme-linked immunosorbent assay), expression of TLR4, NF-κB p65 and phosphorylated NF-κB p65 (p-NF-κB p65) (by Western blot) and for microscopic examination of the pathological changes of hippocampal CA1 region after HE staining. Results:Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, the TLR4 expression was up-regulated, the ratio of p-NF-κB p65/NF-κB p65 was increased, the levels of serum S100β protein and NSE and hippocampal IL-1β, IL-6 and TNF-α were increased ( P<0.05), and the pathological changes in the hippocampal CA1 region were aggravated in group S. Compared with group S, the escape latency was significantly shortened, the number of crossing the original platform was increased, TLR4 expression was down-regulated, the ratio of p-NF-κB p65/NF-κB p65 was decreased, the levels of S100β and NSE in serum and hippocampal IL-1β, IL-6 and TNF-α were decreased ( P<0.05), and the pathological changes in hippocampal CA1 area were significantly attenuated in group P. Conclusions:The mechanism by which multiple exposures to sevoflurane anesthesia induces long-term cognitive impairment is related to activation of TLR4/NF-κB signaling pathway and increase in hippocampal inflammatory responses in neonatal rats.
