RESUMO
Objective:To analyze the effect of donepezil hydrochloride combined with memantine on cognitive function in patients with Alzheimer's disease (AD).Methods:A randomized controlled trial was conducted among 90 patients with AD who were treated at the Zaozhuang Mental Health Center from January 2021 to March 2023. The patients were divided into a donepezil group and a combination group using a random number table grouping method, with 45 patients in each group. The donepezil hydrochloride group received only oral administration of donepezil hydrochloride tablets, while the combination group received oral administration of both donepezil hydrochloride tablets and memantine tablets. The two groups were continuously treated for 12 weeks. Before and after treatment, the Activities of Daily Living scale (ADL) score, the Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD) score, the Mini-Mental State Scale (MMSE) score, and biochemical indicators (homocysteine, neuron-specific enolase, and S100 β) were compared between the two groups. Adverse drug reactions were observed in each group.Results:After treatment, the ADL, BEHAVE-AD, and MMSE scores in the combination group were (78.9 ± 6.1) points, (5.2 ± 0.5) points, and (22.8 ± 2.2) points, respectively, and they were (65.2 ± 5.9) points, (9.6 ± 0.9) points, and (19.4 ± 2.4) points, respectively, in the donepezil hydrochloride group. The ADL and MMSE scores in the combination group were significantly higher than those in the donepezil hydrochloride group ( t = 10.83, 7.01, both P < 0.001). The BEHAVE-AD score in the combination group was significantly lower than that in the donepezil hydrochloride group ( t = -28.67, P < 0.001). After treatment, serum levels of homocysteine, neuron-specific enolase, and S100 β in the combination group were (17.8 ± 3.6) μmol/L, (16.8 ± 2.7) μg/L, and (17.4 ± 7.5) μg/L, respectively, which were significantly lower than (21.5 ± 3.3) μmol/L, (20.4 ± 3.7) μg/L, and (23.5 ± 5.1) μg/L in the donepezil hydrochloride group ( t = -5.08, -5.27, -4.51, all P < 0.001). The incidence of adverse drug reactions in the combination group was 13.3% (6/45), which was slightly, but not significantly, higher than 8.9% (4/45) in the donepezil group ( χ2 = 0.45, P = 0.502). Conclusion:The combination of donepezil hydrochloride and memantine can effectively improve the mental and behavioral symptoms and cognitive function of patients with AD, improve daily living ability, and do not increase adverse reactions. The combined therapy has high clinical application value.
RESUMO
Objective:To explore the value of 18F-FDG PET/CT combined with pro-gastrin-releasing peptide (ProGRP) and neuron-specific enolase (NSE) in diagnosis and differential diagnosis of stageⅠA small cell lung cancer (SCLC). Methods:From June 2017 to October 2021, 113 patients (75 males, 38 females; age 32-79 years) with stageⅠA lung cancer (70 with adenocarcinoma, 25 with squamous cell carcinoma, 18 with SCLC; patients with adenocarcinoma and squamous cell carcinoma were combined into non-SCLC (NSCLC) group) and 30 patients with benign pulmonary nodule (21 males, 9 females; age 37-77 years) from the Affiliated Qingdao Central Hospital of Qingdao University were retrospectively analyzed. All patients were examined by 18F-FDG PET/CT and serum tumor markers associated with lung cancer. Differences of the clinical, imaging and tumor markers data among different groups were analyzed by χ2 test, Fisher exact test and Kruskal-Wallis rank sum test. Independent risk factors were analyzed by logistic regression analysis and ROC curve analysis was used to analyze the value of different predictive factors in diagnosis and differential diagnosis of SCLC. Results:There were significant differences in SUV max, lobulation sign, spiculation sign, calcification, pleural traction sign, ProGRP, NSE and carcinoembryonic antigen (CEA) among SCLC, NSCLC and benign nodules groups ( H values: 14.06-20.54, χ2 values: 8.16-14.95, all P<0.05), in which lobulation sign of SCLC was more than that of benign nodules (12/18 vs 26.7%(8/30); χ2=7.41, P=0.007), spiculation sign (2/18 vs 51.6%(49/95); χ2=10.01, P=0.002) and pleural traction sign (1/18 vs 35.8%(34/95); χ2=6.47, P=0.011) were less than those of NSCLC, SUV max was higher than that of benign nodules (7.4(5.8, 9.0) vs 2.3(1.4, 5.1); H=51.82, P<0.001), ProGRP was higher than that of NSCLC and benign nodules (64.0(40.1, 84.8) vs 38.7(26.9, 47.6), 36.7(29.1, 40.5) ng/L; H values: 36.13, 43.96, P values: 0.002, 0.001) and NSE was higher than that of benign nodules (12.4(10.9, 14.5) vs 7.4(5.4, 11.8) μg/L; H=40.53, P=0.001). When differentiated SCLC from NSCLC, spiculation sign (odds ratio ( OR)=0.043, 95% CI: 0.004-0.450, P=0.009) and ProGRP ( OR=1.083, 95% CI: 1.035-1.133, P<0.001) were independent risk factors for SCLC, and the AUC of the two factors combination was 0.875, with the sensitivity and specificity of 14/18 and 84.2%(80/95). When differentiated SCLC from benign nodules, SUV max( OR=2.706, 95% CI: 1.099-6.662, P=0.030), ProGRP ( OR=1.165, 95% CI: 1.009-1.344, P=0.038) and NSE ( OR=1.639, 95% CI: 1.016-2.645, P=0.043) were independent risk factors for SCLC, and the AUC of the three factors combination was 0.985, with the sensitivity and specificity of 17/18 and 96.7%(29/30). Conclusion:18F-FDG PET/CT combined with tumor markers ProGRP and NSE is helpful to improve the diagnosis and differential diagnosis of stage ⅠA SCLC.

RESUMO
Objective:To investigate the effect of target-controlled infusion propofol combined with inhalation sevoflurane to maintain anesthesia on the postoperative changes of serum β-amyloid protein (β-AP), neuron specific enolase (NSE) and cognitive function in elderly patients with non-small cell lung cancer (NSCLC).Methods:The clinical data of 78 elderly patients with NSCLC who underwent thoracoscopic surgery from December 2017 to December 2019 in Jinhua Hospital of Traditional Chinese Medicine of Zhejiang Province were retrospectively analyzed. Among them, target-controlled infusion propofol to maintain anesthesia was in 39 cases (control group), and target-controlled infusion propofol combined with inhalation sevoflurane to maintain anesthesia was in 39 cases (study group). The serum levels β-AP, NSE and cognitive function (assessed by mini mental state examination, MMSE) before and after operation, the postoperative recovery (eye opening time, response time and extubation time) and incidence of adverse reactions were compared between 2 groups.Results:There were no statistical differences in β-AP and NSE before operation between 2 groups ( P>0.05); the β-AP and NSE immediately and 6 h after operation in study group were significantly lower than those in control group, β-AP: (416.13 ± 22.81) μg/L vs. (510.73 ± 24.27) μg/L and (373.53 ± 21.72) μg/L vs. (430.68 ± 22.15) μg/L, NSE: (8.35 ± 0.66) μg/L vs. (11.13 ± 0.73) μg/L and (7.81 ± 0.61) μg/L vs. (9.12 ± 0.68) μg/L, and there were statistical differences ( P<0.01); there were no statistical differences in β-AP and NSE 24 h after operation between 2 groups ( P>0.05). There was no statistical difference in MMSE score before operation between 2 groups ( P>0.05); the MMSE score 6, 24 and 72 h after operation in study group was significantly higher than that in control group: (22.32 ± 2.05) scores vs. (20.54 ± 2.31) scores, (25.19 ± 1.33) scores vs. (23.61 ± 1.08) scores and (26.84 ± 0.97) scores vs. (25.01 ± 1.15) scores, and there was statistical difference ( P<0.01); there was no statistical difference in MMSE score 7 d after operation between 2 groups ( P>0.05). The eye opening time, response time and extubation time in study group were significantly shorter than those in control group: (14.15 ± 3.20) min vs. (19.32 ± 3.14) min, (18.08 ± 3.52) min vs. (24.63 ± 4.10) min and (16.21 ± 4.40) min vs. (22.31 ± 4.71) min, and there were statistical differences ( P<0.01). There was no statistical difference in the incidence of adverse reactions between 2 groups ( P>0.05). Conclusions:Target-controlled infusion propofol combined with inhalation sevoflurane to maintain anesthesia in elderly patients with NSCLC can reduce the increase of serum levels of β-AP and NSE, reduce the damage to cognitive function, make patients recover quickly after operation, and will not increase the incidence of adverse reactions. Its security is higher.
RESUMO
Objective:To investigate the values of serum neuron specific enolase (NSE), circulating tumor cells (CTC) and lactate dehydrogenase (LDH) levels in the diagnosis and treatment of small cell lung cancer (SCLC).Methods:Ninety patients with SCLC who received treatment in the Second Affiliated Hospital of Zhejiang Chinese Medical University, China between December 2017 and December 2019 were retrospectively included in the observation group. Ninety healthy subjects who concurrently received lung examination in the same hospital were included in the healthy control group. An additional 90 patients with benign lung disease were included in the benign lung disease group. Serum NSE, CTC and LDH levels were determined in each group. The values of serum NSE, CTC and LDH levels in the diagnosis of SCLC were analyzed. Serum NSE, CTC and LDH levels were compared between before and after chemotherapy and their values in the treatment of SCLC were analyzed.Results:There were significant differences in serum NSE, CTC and LDH levels between three groups ( F = 359.789, 188.873 and 768.704, all P < 0.001). Serum NSE, CTC and LDH levels in the benign lung disease group were significantly greater than those in the healthy control group and significantly lower than those in the observation group. The receiver operating characteristic curve (ROC curve) analysis showed that the AUC values of serum NSE, CTC and LDH levels in the diagnosis of SCLC were 0.995, 0.953 and 0.987, respectively. The diagnostic accuracy was very high. The value at the maximum tangent point of Youden's index of serum NSE, CTC and LDH levels at the left-upper corner of the ROC curve was taken as the most appropriate cut-off value. The sensitivity and specificity of the most appropriate cut-off value of serum NSE, CTC and LDH levels in the prediction of SCLC were 100.0%/94.4%/91.1% and 94.4%/88.3%/100.0%, respectively. Therefore, serum NSE, CTC and LDH levels were of high values in the predication of SCLC. After chemotherapy, serum NSE, CTC and LDH levels in patients with SCLC were significantly lower than those before chemotherapy [NSE: (12.26 ± 3.26) μg/L vs. (18.36 ± 4.64) μg/L; CTC: (3.54 ± 1.08) counts/5 mL vs. (7.34 ± 1.30) counts/5 mL; LDH: (24.61 ± 9.66) U/L vs. (50.29 ± 16.29) U/L, t = 10.205, 12.864, 21.330, all P < 0.001). Serum NSE, CTC and LDH levels in SCLC patients in whom treatment was effective were significantly lower than those in SCLC patients in which treatment was not effective ( t = 8.111, 7.347, 10.731, all P < 0.001). Spearman correlation results showed that serum NSE, CTC and LDH levels were significantly negatively correlated with curative effects ( r = -0.562, -0.562, -0.758, all P < 0.05). Conclusion:Serum NSE, CTC and LDH levels are highly expressed in SCLC patients, which can be used as markers for early clinical diagnosis and treatment of SCLC.
RESUMO
ABSTRACT Objective: To investigate the diagnostic value of α-enolase (ENO1) and serum ENO1 autoantibody levels in lung cancer. Methods: Immunohistochemistry staining and ELISA were performed to detect ENO1 expression in lung tissue and serum ENO1 autoantibody levels, respectively. Results: The expression of ENO1 was higher in lung cancer tissues than in benign lung disease tissues (p < 0.001). The proportion of lung cancer samples expressing ENO1 was not significantly different among the various pathological classification groups. The proportion of samples expressing ENO1 was higher in lung cancer patients in stages I/II than in those in stages III/IV (χ2 = 5.445; p = 0.018). The expression of ENO1 in lung cancer tissues was not associated with age, gender, or smoking history. Serum ENO1 antibody levels were significantly higher in the lung cancer group than in the benign lung disease and control groups (p < 0.001). The differences among the pathological classification groups were not statistically significant. Serum ENO1 antibody levels were also in lung cancer patients in stages I/II than in those in stages III/IV (p < 0.01). Serum ENO1 antibody levels were not associated with age, gender, or smoking history in lung cancer patients. The ROC curve representing the diagnosis of lung cancer based on ENO1 antibody levels had an area under the curve of 0.806. Conclusions: Our results suggest that high levels of ENO1 are associated with the clinical stage of lung cancer and that ENO1 expression and its serum autoantibody levels show diagnostic value in lung cancer.
RESUMO Objetivo: Investigar o valor diagnóstico da α-enolase (ENO1) e dos níveis séricos de autoanticorpos contra ENO1 no câncer de pulmão. Métodos: Marcação imuno-histoquímica e ELISA foram realizados para detectar a expressão de ENO1 no tecido pulmonar e os níveis séricos de autoanticorpos contra ENO1, respectivamente. Resultados: A expressão de ENO1 foi maior nos tecidos de câncer de pulmão que nos tecidos de doença pulmonar benigna (p < 0,001). Não houve diferença significativa entre os diversos grupos de classificação patológica quanto à proporção de amostras de câncer de pulmão que expressaram ENO1. A proporção de amostras que expressaram ENO1 foi maior nos pacientes com câncer de pulmão nos estágios I/II que naqueles com câncer de pulmão nos estágios III/IV (χ2 = 5,445; p = 0,018). Não houve relação entre a expressão de ENO1 em tecidos de câncer de pulmão e idade, sexo ou histórico de tabagismo. Os níveis séricos de anticorpos contra ENO1 foram significativamente maiores no grupo câncer de pulmão que nos grupos doença pulmonar benigna e controle (p < 0,001). As diferenças entre os grupos de classificação patológica não foram estatisticamente significativas. Os níveis séricos de anticorpos contra ENO1 foram também significativamente maiores nos pacientes com câncer de pulmão nos estágios I/II que naqueles com câncer de pulmão nos estágios III/IV (p < 0,01). Nos pacientes com câncer de pulmão, não houve relação entre os níveis séricos de anticorpos contra ENO1 e idade, sexo ou histórico de tabagismo. A curva ROC do diagnóstico de câncer de pulmão baseado nos níveis de anticorpos contra ENO1 apresentou área sob a curva = 0,806. Conclusões: Nossos resultados sugerem que há relação entre níveis elevados de ENO1 e o estágio clínico do câncer de pulmão e que a expressão de ENO1 e os níveis séricos de autoanticorpos contra ENO1 têm valor diagnóstico no câncer de pulmão.

Objective To systematically evaluate the influence of TNF-α and NSE levels in cerebrospinal fluid on Chinese children with viral encephalitis (VE).Methods Literature about the influence of TNF-α and NSE levels in cerebrospinal fluid on Chinese children with VE,which were published before Nov.1,2016,were searched in databases including CNKI,Wanfang Data,Cochrane Library and PubMed.And the case-control study about the TNF-α and NSE levels in cerebrospinal fluid between Children with VE (VE group) and children without VE (control group) were included in this study,and the quality evaluation was implemented and the data were extracted.And then the RevMan 5.3 was used to carry out the meta-analysis.Results Nine case-control studies were included in this study,involving 536 cases in the VE group and 284 cases in the control group.The results showed that the level of TNF-α and NSE in cerebrospinal fluid of the VE group were all significantly higher than that of the control group,and the differences was statistically significant [SMD=1.75,95%CI:1.56-1.93,P<0.01;SMD=1.34,95%CI:1.17-1.51,P<0.01].Conclusion The levels of TNF-α and NSE in cerebrospinal fluid are positively correlated with the incidence of VE in Chinese children.
RESUMO
Objective To detect the varicella-zoster virus (VZV) DNA load in vesicle fluid and peripheral blood,as well as plasma levels of S100β protein and neuron-specific enolase (NSE) in patients with herpes zoster before and after treatment,and to explore their correlations.Methods Vesicle fluid samples were collected before treatment,and peripheral blood samples before and after treatment from 50 inpatients with acute herpes zoster in the Department of Dermatology of the Affiliated Hospital of Southwest Medical University,and peripheral blood samplcs were also obtained from 20 heahhy controls.Real-time fluorescence-based quantitative PCR (qRT-PCR) was performed to determine the viral load in the vesicle fluid and peripheral blood samples,and enzyme-linked immunosorbent assay (ELISA) to detect the plasma levels of S100β protein and NSE.Results VZV DNA was present in all the vesicle fluid samples,as well as in peripheral blood samples from 18 patients before treatment and 5 patients after treatment,but not found in any of the healthy controls.Positive correlation was found bctween the viral load in vesicle fluid and plasma levels of S 100β protein and NSE (r =0.535,0.430,respectively,both P < 0.05) in the patients with acute herpes zoster.Before treatment,patients with VZV DNA in peripheral blood showed significantly increased plasma levels of S100β protein and NSE compared with those without (both P < 0.05),and the viral load in peripheral blood was positively correlated with plasma levels of S100β protein and NSE (r =0.711,0.645,respectively,both P < 0.05).Conclusion VZV DNA is present in some patients with herpes zoster,and increased VZV DNA loads in the vesicle fluid and peripheral blood are related to elevated plasma levels of S100β protein and NSE before treatment.
RESUMO
BACKGROUND/AIMS: It is not clear which tests are indicative of the activity and severity of tuberculosis (TB). This study aimed to investigate the predictive value of neuron-specific enolase (NSE) and to determine the origin of NSE in TB patients. METHODS: A single-center retrospective analysis was conducted on newly diagnosed TB patients between January and December 2010. Patients were categorized into one of two disease groups (focal segmental or extensive) based on chest X-ray. Pre- and post-treatment NSE concentrations were evaluated. To determine the origin of serum NSE concentration, NSE staining was compared with macrophage-specific CD68 staining in lung tissues and with a tissue microarray using immunohistochemistry and immunofluorescence. RESULTS: A total of 60 newly diagnosed TB patients were analyzed. In TB patients, NSE serum concentration was significantly increased and NSE level decreased after treatment (p < 0.001). In proportion to serum high-sensitivity C-reactive protein concentration, the mean serum concentration of NSE in the extensive group (25.12 ng/mL) was significantly higher than that in the focal segmental group (20.23 ng/mL, p = 0.04). Immunohistochemical staining revealed a large number of macrophages that stained positively for both NSE and CD68 in TB tissues. In addition, NSE signals mostly co-localized with CD68 signals in the tissue microarray of TB patients. CONCLUSIONS: Our results suggest that NSE may be a practical parameter that can be used to monitor TB activity and treatment response. Elevated serum NSE level originates, at least in part, from macrophages in granulomatous lesions.

RESUMO
Objective To investigate the effect of construct the Notch1 (NICD) eukaryotic expression vector on the proliferation and differentiation of rat bone marrow mesenchymal stem cells (BMSCs) in vitro. Methods Rat BMSCs were experimented as the object. NICD eukaryotic expression vector was constructed. pEGFP-N1-NICD expressing plasmids were used to transfect BMSCs. The study included control group (CON group), empty vector group (VEC group) and the trans-fection group (TRA group). After 48-hour transfection, BMSCs were observed for general morphology. The protein expres-sions of NSE, GFAP and Notch1 were detected by real-time PCR and Western blotting assay respectively. The apoptosis, cy-cle distribution and cell proliferation were evaluated by flow cytometry and MTT assay. Results The DNA sequencing con-firmed that the pEGFP-N1-NICD recombinant plasmid was successfully constructed, and both VEC group and TRA group expressed green fluorescence after 48-hour transfection. The relative expression levels of Notch1 and GFAP mRNA and pro-tein were significantly higher in TRA group than those in VEC group and CON group (P<0.05), and there was no significant difference between VEC group and CON group. After 48-hour transfection, the ratio of living cells was significantly lower in TRA group than that of CON group and VEC group, and the early apoptotic rate and late apoptotic rate were significantly higher in TRA group than those of CON group and VEC group (P<0.05). The late apoptotic rate was significantly higher in VEC group than that of CON group. The proportion of G1/G0 cells was significantly higher in TRA group than that of CON group and VEC group, but S and G2/M cells were significantly lower (P<0.05). The value of growth curve was gradually de-creased in TRA group than that of CON group and VEC group (P<0.05). Conclusion The high expression of NICD gene might induce apoptosis of BMSCs, inhibit the proliferation in part, and induce into glial-like cell differentiation.
