ABSTRACT
Objective:To explore the risk factors of spontaneous rupture of hepatocellular carcinoma (HCC), and to analyze the prognosis of transcatheter arterial embolization (TAE) in the treatment of spontaneous rupture of HCC.Methods:From January 2008 to December 2018, at Tianjin Third Central Hospital, 126 patients diagnosed with spontaneous rupture of HCC (spontaneous rupture group) and in the same period 252 patients diagnosed as HCC without rupture (non-spontaneous rupture group) were retrospectively selected. Independent sample t test, Mann-Whitney U test and chi-square test were used to compare the general data, laboratory test results and imaging results between spontaneous rupture group and non-spontaneous rupture group. Multivariate logistic regression was used to analyze the independent risk factors of spontaneous rupture of HCC. Kaplan-Meier method and log-rank test were used for survival analysis of 92 patients treated with TAE and 31 patients treated with conservative treatment in patients with spontaneous rupture of HCC, and multivariate Cox proportional hazard regression was used to analyze the independent prognostic factors of patients treated with TAE. Results:The proportions of tumor maximum diameter ≥5 cm, tumors mainly located in segment Ⅱ, Ⅲ, Ⅳ and Ⅵ of the liver, tumors protruding height from the surface of liver ≥1 cm, liver cirrhosis and portal vein thrombosis (PVT) in spontaneous rupture group were all higher than those in non-spontaneous rupture group (46.8%, 59/126 vs. 35.7%, 90/252; 61.1%, 77/126 vs. 46.0%, 116/252; 73.0%, 92/126 vs. 18.7%, 47/252; 81.7%, 103/126 vs. 69.0%, 174/252; 20.6%, 26/126 vs. 11.5%, 29/252), and the level of fibrinogen is lower than that in non-spontaneous rupture group ((3.07 ±1.38) g/L vs. (3.92±1.13) g/L), and the differences were statistically significant ( χ2=4.343, 7.644, 106.780, 6.918 and 5.628, t=-3.276, all P<0.05). The results of multivariate logistic regression analysis showed that the location of tumors in segment Ⅱ, Ⅲ, Ⅳ, Ⅵ of the liver, the height of tumors protruding from the surface of liver ≥1 cm, liver cirrhosis and the fibrinogen was lower than the lower limit of the reference value were independent risk factors of spontaneous rupture of HCC (odds ratio ( OR)=1.354, 5.726, 1.152, 1.892; 95% confidence interval ( CI) 1.062 to 2.008, 1.049 to 19.575, 1.016 to 1.895, 1.267 to 3.346; all P<0.05). Among 92 patients with spontaneous rupture of HCC treated with TAE, the TAE technical success rate and clinical success rate were 100.0% (92/92) and 93.5% (86/92), respectively. Thirty-one patients received conservative treatment. The median survival time of the patients treated with TAE was 243 d (38 d, 377 d), which was about 10 times that of the patients who accepted conservative treatment (23 d (9 d, 51 d)). The 1-month, 3-month, 6-month, 1-year and 3-year survival rates of the patients treated with TAE were 72.8%, 50.8%, 46.0%, 31.1% and 13.6%, respectively, and those of patients who accepted conservative treatment were 25.8%, 17.2%, 11.5%, 5.7% and 0, respectively; and the differences in survival rates between the two groups were statistically significant ( χ2=34.606, P<0.01). Log-rank test analysis showed that initial hemoglobin <60 g/L, C grade of liver function, total bilirubin (TBil)≥50 μmol/L, complicated with portal vein tumor thrombus, hepatic lobe embolism during TAE, and tumor maximum diameter ≥10 cm were all correlated with poor survival rates of patients with spontaneous rupture of HCC after TAE ( χ2=3.752, 4.146, 22.318, 4.087, 5.685 and 7.893, all P<0.05). The results of multivariate Cox proportional hazard regression analysis showed that TBil ≥ 50 μmol/L, hepatic lobe embolism during TAE, and tumor maximum diameter ≥10 cm were independent factors of poor prognosis of spontaneous rupture of HCC treated with TAE ( OR=25.873, 8.415, 18.620; 95% CI 4.916 to 126.005, 1.136 to 27.319, 2.754 to 84.368; all P<0.05). Conclusions:In HCC patients with tumors located in segments Ⅱ, Ⅲ, Ⅳ and Ⅵ of the liver, the height of tumors protruding from the surface of liver ≥1 cm, liver cirrhosis or the fibrinogen is lower than the lower limit of the reference value, close attention should be paid to the risk of spontaneous tumor rupture. TAE is an effective treatment for acute spontaneous rupture of HCC, and the prognosis of patients treated with TAE is better than that of patients receiving conservative treatment. However, patients with TBil ≥50 μmol/L, hepatic lobe embolism during TAE and tumor maximum diameter ≥10 cm have a poor prognosis after TAE treatment.
ABSTRACT
@#This study aimed to investigate the effects of fusion proteins GnRH-GRP(G3G6)and HSP65-STEAP1(HST1)on dendritic cells(DC)and the sensitization of DCs to B16F10 melanoma. The fusion proteins G3G6 and HST1 were obtained using the previous engineering strains in our laboratory. Group by unsensitized DC(US-DC), the G3G6 fusion protein sensitized DC, the HST1 fusion protein sensitized DC(HST1-DC)and the combined sensitized DC(GH-DC), the mouse bone marrow-derived DCs were sensitized with fusion protein to obtain the fusion protein sensitized DC vaccines. B16F10 melanoma cells were transplanted into C57BL/6J male mice to construct a melanoma model(1×106 cells per mouse), and DC vaccine was injected for treatment. The antitumor efficacy of DC vaccine was explored by in vitro and in vivo experiments. Flow cytometry analysis showed that the fusion protein can effectively stimulate DC into differentiation and maturation; in the animal experiment, the inhibition rate of melanoma treated with G3G6-DC was 35. 75%, that of HST1-DC group and combination group were 34. 03% and 55. 74%. It was initially proved that both G3G6-DC and HST1-DC can effectively inhibit the growth of transplanted tumors of melanoma B16F10 cells in mice, and the combination therapy is superior to the single therapy.
ABSTRACT
Objective@#To explore the effect of distance education in the teaching mode of medical clinical skills, and to provide theoretical and practical basis for finding a better teaching mode to promote the combination of theory and practice.@*Methods@#A total of 172 trainees of clinical skill training in the training center were divided into the control group and the observation group (the observation group was divided into pre-class long-distance group, in-class long-distance group, after-class long-distance group). There were 43 trainees in each group. The control group adopted traditional teaching methods in clinical basic skills courses, and the observation group adopted mixed teaching mode under long-distance education. The satisfaction of teachers and students under the two teaching modes were investigated, and the performance of each group of students in skills, human-computer dialogue, and team first aid comprehensive test were compared.@*Results@#There were significant differences in teacher satisfaction between the control group and the pre-class and in-class distance groups (χ2 = 15.315, P = 0.000). There were significant differences in student satisfaction between the control group and the pre-class and in-class distance groups in terms of interactive participation, liveliness, interesting training skills and teaching level (χ2=4.497-17.153, P = 0.000-0.034). The results of each group reached the expected teaching goals. There were significant differences between the skill test score control group and the pre-class and in-class remote groups (t=25.357, 14.712, all P =0.000). There were significant differences between the human-machine dialogue test control group and the three observation groups (t=14.561, 19.420, 3.821, all P =0.000). There were significant differences between the team emergency comprehensive test control group and the three observation groups (t=14.561, 19.420, 3.821, all P=0.000).@*Conclusions@#Distance education has flexible in the mixed teaching mode of clinical skills, especially in pre-class and in-class.

ABSTRACT
Objective To explore the impairment of attention network function in male patients with alcohol use disorder(AUD) and the main influencing factors of attention network function. Methods Forty-one patients with AUD after withdrawal therapy and 34 healthy controls (HC) matched with their demograph-ic data were selected as subjects of study. Attention function were assessed by attention network test (ANT). Results Compared with the healthy control group((30. 62±19. 74)ms,(98. 59±1. 46)%),there were sig-nificant differences in the reaction time of alerting network(t=-2. 479,P=0. 015) and the correct rate of the attention network test(t=-2. 074,P=0. 044) in the AUD group((17. 02±26. 42)ms,( 95. 07±10. 73)%). Pearson correlation analysis showed the alert network of AUD was negatively correlated with the age of first drinking(r=-0. 316,P=0. 044) and was positively correlated with the score of Penn alcohol craving scale (PACS) (r=0. 364,P=0. 019). The correct rate of attention network function in patients with AUD was negatively correlated with the years for education ( r=-0. 343, P=0. 028) and years for addiction ( r=-0. 337,P=0. 031). Linear regression analysis showed the attention network function of AUD patients was affected by the age of first drinking(β=0. 432,t=2. 079,P=0. 046),the years for addiction(β=-0. 555,t=-3. 127,P=0. 004) and years for uncontrol drinking(β=0. 309,t=2. 074,P=0. 047). Conclusion The AUD patients were demonstrated deficit in the alerting network. The impairment of attention function of AUD patients were influenced by their drinking condition.

ABSTRACT
Objective To explore the clinical characteristics and perioperative treatment of chronic obstructive pulmonary disease (COPD) in patients with non-small-cell lung cancer (NSCLC) in department of thoracic surgery,and to guide the clinical diagnosis and treatment. Methods From January 2013 to December 2016,patients with newly diagnosed NSCLC treated in the thoracic surgical department of Lanzhou University Second Hospital were reviewed retrospectively. The patients were divided into the COPD group and non-COPD group. The clinical data,including the incidence and clinical characteristics of COPD in non-small-cell lung cancer,pulmonary complications after surgery,COPD diagnosis and perioperative pulmonary rehabilitation were analyzed retrospectively. Results A total of 726 NSCLC patients were reviewed,six hundred and seventy-five cases who took the full lung function test were included in the study,of which 95 cases received bronchial diastolic test,86 cases were accorded with COPD diagnosis and were included in incorporated COPD group,and 589 cases were in the non- incorporated COPD group. The proportion of men (69 cases,80. 2%,χ2 = 24. 032), age ≥65 (51 cases,59. 3%,χ2 = 6. 784),smoking history (55cases,64. 0%,χ2 = 29. 474) and a large number of smokers (43 cases,50. 0%,χ2 = 5. 802) and lung squamous cell carcinoma(47 cases,54. 7%,χ2 = 6. 241) in the incorporated COPD group were higher than those in differences were statistically significant (P<0. 05); the incidence of pulmonary complications after radical resection of lung cancer in the incorporated COPD group was 23. 9% (16/ 67),which was significantly higher than that in the unincorporated COPD group(13. 7% (78/568)) (χ2 = 4. 894,P<0. 05). The incidence of pulmonary complications in the lung rehabilitation group was 13. 5% ( 5/37) , lower than that of the non-lung rehabilitation group ( 36. 7% ( 11/30 ) ) (χ2 = 4. 886, P<0. 05);Among the 86 cases (12. 7%) of incorporated COPD,only 6 cases (8. 9 ‰) were diagnosed with COPD at the time of admission, and 23 cases ( 3. 4%) at discharge. No COPD guidelines were given. Conclusion NSCLC often combined wtith COPD,especially in males,elders (≥65 years old) ,smokers, squamous cell carcinoma patients. At present,the diagnosis and treatment of co-morbidity of COPD is seriously inadequate,which needs to be paid much attention to by the thoracic surgeons,in order to improve the diagnosis and treatment of COPD,and improve the prognosis of the patients with NSCLC and COPD.
ABSTRACT
Purpose To discuss the correlation between ultrasonic structural malformation and chromosomal microarray analysis (CMA) to provide a reliable basis for establishment of a prenatal diagnosis process of fetal malformation.Materials and Methods 104 pregnant women with structural malformation,who received prenatal ultrasonic screening in Obstetrics and Gynecology Hospital Affiliated to Nanjing Medical University,were subjected to CMA detection.According to the results,they were divided into pathogenic group,Vous group and normal group,and the ultrasonic results and CMA results were compared and analyzed.Results Fifteen cases (14.42％) in the pathogenic group,including 9 cases of fetal aneuploidy,and 6 cases of microdeletion or mirco repetitive fetuses;28 cases (26.92％) in the Vous group and 61 cases (58.65％) in the normal group.There were 12 cases of two or more systems of deformity in the pathogenic group,in which the most common was complex congenital heart disease (9 cases),followed by nasal bone loss (4 cases);in the normal group and Vous group,most were single-system malformation,and the difference among three groups was statistically significant (x2=17.34,P＜0.01).There were 4 cases of pathogenic chromosomal abnormalities in the 17 cases of high risk pregnant women.Conclusion In prenatal counseling,if the fetus is found to have the malformation of two or more systems;the malformation variety contains complex congenital heart disease,nasal bone loss or malformation of other parts;high risk pregnant women combined with fetal structural malformation should be proposed to receive CMA detection to eliminate pathogenic chromosomal abnormalities.

ABSTRACT
Objective To investigate the health information literacy (HIL) conditions of patients after percutaneous coronary intervention (PCI) operation and to discuss the influence of HIL on the nursing knowledge acquisition behavior of the patients. Methods A total of 230 postoperative PCI patients who accepted treatment in Cardiology Department of our hospital were selected. General information questionnaire, 2012 National Residents Health Literacy Supervision Investigation Questionnaire-HIL part and nursing knowledge acquisition behavior questionnaire were adopted. Results In this investigation, 230 questionnaires were recovered and 216 of them were effective. HIL level of PCI postoperative patients was 24.1％ (52/216). Differences in HIL levels of patients of different ages, residential areas and educational degrees were of statistical significance (χ2=10.577, 12.657, 37.693, P<0.05). The scores of PCI postoperative exercise method and item analysis of PCI therapy institution and nursing knowledge obtained from medical care personnel, books, Internet and speeches in patients with HIL were 3.40±0.85, 3.35 ± 0.71, 3.37 ± 0.82, 3.75 ± 0.74, 3.54 ± 0.75 and 3.71 ± 0.82. They were significantly higher than the scores of 2.38±0.71, 2.40±0.76, 2.34±0.71, 2.48±0.75, 2.45±0.72 and 2.43±0.78 in the non HIL patients (t=6.657-9.000, P<0.05). The scores of nursing knowledge in coronary heart disease symptoms, PCI postoperative complications and aetiological agent of coronary heart disease,nursing knowledge sources of newspapers, TV and radio, relatives, and nursing knowledge acquisition barriers due to low educational level, incomprehension of terminology and lack of Internet knowledge of the patients with HIL were 2.37± 0.82, 2.63 ± 0.89, 2.42 ± 0.82, 2.37 ± 0.79, 2.50 ± 0.67, 2.48 ± 0.67, 2.46 ± 0.64, 2.46 ± 0.85, 2.54 ± 0.87 and 2.63±0.69. They were significantly lower than the scores of 3.43±0.78, 3.38±0.76, 3.45±0.74, 3.49±0.77, 3.32 ± 0.81, 3.41 ± 0.77 and 3.34 ± 0.83, 3.46 ± 0.70, 3.43 ± 0.74 and 3.41 ± 0.75 in the non HIL patients (t=-5.657-4.690, P<0.05).

ABSTRACT
We determined the in vitro antioxidant and antimicrobial activities of Platycarya strobilacea infructescence [PSI] from various solvent extracts [methanol, ethyl acetate, water and tannin polymers] and quantified the content of total phenolic of each extract. The ethyl acetate extract was found to have the best radical-scavenging activity and ferric reducing power, as well as antimicrobial activity. In order to investigate the protective effect on oxidative stress in vivo, each extract was administered to rats, and the serum, liver and heart were analyzed. The water extract and tannin polymers significantly decreased malonyldialdehyde [MDA] concentrations in serum, liver and heart compared to the control group [P<0.01]. Furthermore, super oxide dismutase [SOD] and glutathione per oxidase [GSH-Px] activities were increased by administration of all extracts. We concluded that the ethyl acetate extract of PSI has strong antioxidant activity in vitro and possesses antimicrobial activity. These results indicated PSI the potential of medicinal uses and food preservation
ABSTRACT
Objective To study the significance of treating advanced primary hepatic carcinoma by using the different methods combined with chemotherapy. Methods One hundred and fifteen cases with advanced primary hepatic carcinoma were divided into 5 groups by accepting different chemotherapy: the groups of interventional-chemotherapy (group A, 40 cases), whole body hyperthermia combined with chemotherapy (group B, 16 cases), only chemotherapy (group C, 9 cases), local heat chemotherapy (group D, 26 cases), symptomatic supportive (group E, 24 cases) for comparing response rate (RR) and survival time between each other. Results The RR in group A,B,C were 30.5 % (12/40), 12.5 % (2/16), 11.1 % (1/9) respectively, and there was no significant difference among three groups (P>0.05). The mid-survival time of five groups were 7.7, 9.2, 7.9, 6.0, 4.7 months, and there was significant difference between group B and group E (P<0.05). The 0.5-, 1-, 2-year survival rate in group B were higher than those in group E with significant difference (81.2%vs. 29.1%, 37.5%vs. 12.5%, 12.5%vs. 0, all P<0.05). Conclusions The RR of only routine chemotherapy is low, while the RR of interventional-chemotherapy and local heat chemotherapy is high with non-prolonged survival time. Whole body hyperthermia combined with chemotherapy have active effects in helping to improve the efficacy and prolong the survival time in retreatment patients with advanced hepatic tumor.
ABSTRACT
Objective:To explore the quality on 64-slice CT coronary angiography with different injection rates of contrast agent.Methods: 120 patients who have been diagnosed or suspected coronary atherosclerosis were selected in our hospital and were randomly divided into group A(4.5ml/s), group B(5.0ml/s) and group C(5.5ml/s), with 40 cases in each group. We observed CT attenuation values, image quality, and adverse reactions of the three groups.Results: There were significant differences in the ascending aorta, descending aorta, left main, left anterior descending artery, circumflex artery and the right coronary artery and other parts of the CT attenuation value (F=6.838,F=4.002,F=7.261,F=5.992,F=8.281,F=5.790,F=6.126;P<0.05). In image quality, the group B with 34 cases was significantly better than group A with 12 cases and group C with 20 cases (x2=9.632,x2=5.475;P<0.05). The rate of adverse reactions was 30%, 7.5% and 22.5% with 12 cases in group A, 3 cases in group B and 9 cases in group C. The rate in group B was significantly lower than in group A and group C (x2=12.985,x2=10.236;P<0.05).Conclusion: Through the application of the same concentration of the contrast agent and scan conditions to coronary angiography, we can get a good vascular enhancement and high quality imaging when the injection rate of contrast medium is 5ml/s, while incidence of adverse reactions may be reduced.
ABSTRACT
BACKGROUND:Salvia miltiorrhiza bone-setting capsule is a traditional Chinese medicine for the treatment of fractures due to activating blood circulation to dissipate blood stasis, reducing sweling and pain. OBJECTIVE: To observe the effects of Salvia miltiorrhiza bone-setting capsule on the fracture healing in a rat model of closed femoral fractures. METHODS: Rats were randomly divided into salvia miltiorrhiza bone-setting capsule group, physiological saline group and normal group. In the salvia miltiorrhiza bone-setting capsule group and physiological saline group, rat models of closed femoral fractures were prepared, and then given physiological saline and salvia miltiorrhiza bone-setting capsule 2 pils by intragastric administration. In the normal group, rats were housed normaly. At 7, 14 and 28 days after fractures, hematoxylin-eosin staining conditions, serum osteocalcin, the expression of colagen type I, and the expression of protein and mRNA calus transforming growth factor-beta 1 were observed in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. RESULTS AND CONCLUSION: (1) Hematoxylin-eosin staining demonstrated that at 7 days after fractures, no significant difference was found in pathological changes of femoral fracture in salvia miltiorrhiza bone-setting capsule group and physiological saline group. At 14 and 28 days after fractures, pathological repair was more obvious in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group. (2) At 3 and 7 days after fractures, serum osteocalcin and the expression of type I colagen were significantly increased in the salvia miltiorrhiza bone-setting capsule group and physiological saline group (P < 0.05), and the expression trend was consistent in both groups. The expression was always higher in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group, and significant differences were found at 14 and 28 days after fractures (P < 0.01). (3) Transforming growth factor beta 1 expression reached a peak at 3 days after fractures, gradualy reduced, increased at 14 days (the second peak), and diminished at 28 days in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. The expression trend of transforming growth factor beta 1 was consistent in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. At 7, 14 and 28 days, the transforming growth factor beta 1 expression was higher in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group. (4) Results showed that salvia miltiorrhiza bone-setting capsule could promote fracture healing, and its mechanism was probably associated with serum osteocalcin, the expression of colagen type I and transforming growth factor-β1.

ABSTRACT
BACKGROUND: During conventional treatment for bone tuberculosis, there is a low effective concentration of anti-tuberculosis drugs, and the therapeutic effect is poor. OBJECTIVE:To develop a new biomaterial as a slow-release artificial carrier that can be directly implanted into the surrounding tissue of bone tuberculosis, maintain a certain anti-tuberculosis drug concentration for a long time, thereby playing an effective therapeutic action. METHODS:Rifampicin/polylactic acid/glycolic acid microspheres and isoniazid/polylactic acid/glycolic acid microspheres were prepared using the emulsion-solvent evaporation method. Usingα-cyanoacrylate, a biological adhesive, two kinds of microspheres were processed into a long-term slow-release bicomponent drug carrier. Then, in vitro release characteristics of the dual-drug sustained-release carrier were observed. After that, the dual-drug sustained-release carrier was implanted into rabbit intertrochanteric femur bone defects for observing drug release concentrations, histocompatibility and bone defect healing at different time points after drug delivery carrier implantation. RESULTS AND CONCLUSION:For rifampicin/polylactic acid/glycolic acid microspheres, the mean particle size was (240±13)μm, and the drug loading load rate was (26±1.5)%. For isoniazid/polylactic acid/glycolic acid microspheres, the mean particle size was (250±10)μm, and drug loading rate was (28±1.8)%. The in vitro cumulative release rate could reach 80%for rifampicin and 90%for isoniazid at day 90. The in vivo released concentration of rifampicin and isoniazid within 90 days was (0.5±0.4) and (0.6±0.3)μg/g, respectively. There were a smal amount of infiltrated neutrophils between the fascia and muscle fibers after the drug delivery carrier was implanted, and the amount of neutrophils in the muscle were reduced significantly at day 59. X-ray plain film showed that bone defects decreased obviously in size. These findings indicate that this dual-drug sustained-release carrier can maintain a certain anti-tuberculosis drug concentration in the surrounding tissues of bone tuberculosis, which is expected to provide a new type of dual-drug delivery carrier in the surgical treatment of bone tuberculosis.
ABSTRACT
Objective To investigate thc cvent-based prospective memory (EBPM)and time-based prospective memory(TBPM)in the inpatients with abstinent alcohol dependence and the relationships between prospective memory and symptoms.Methods 32 male patients with alcohol dependence and 30 normal controls matched by age,education,HAMD and HAMA were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.Results A statistically significant in EBPM was observed between patients with alcohol dependence and normal controls (3.91 ± 0.69 vs.4.47 ± 0.63,t =-3.348,P ＜ 0.0 1) and the same result in TBPM (3.28 ±0.77 vs.4.20 ±0.66,t=-5.032,P＜0.01).The positively correlation was showed between the duration of abstinence and EBPM (r =0.444,P ＜ 0.05),as well as TBPM (r =O.423,P ＜ 0.05) in the patients.Conclusion The results suggest abstinent alcohol dependence patients impairs both EBPM and TBPM.PM shows correlated with duration of abstinence moderately in the patients.
ABSTRACT
ObjectiveTo explore the attentional biases in male alcohol dependent (AD) patients and the correlations between the attentional bias and alcohol-related factors.MethodsA total of 30 recently detoxified male individuals with alcoholism were compared with 37 healthy controls ( HC ) on the Chinese Emotional Stroop Task using negative,neutral,and alcohol-related words.ResultsThe comparison between AD group( ( 1382.13 ±323.38) ms,( 1365.76 ±313.03)ms,( 1433.20 ±342.23) ms,respectively) and HC group( (797.27 ±216.97)ms,( 794.11 ± 209.41 ) ms,(799.40 ± 215.82 ) ms respectively) on the reaction time of neutral,negative and alcohol-related words were significant ( t =8.822,P ＜ 0.001 ; t =8.922,P ＜ 0.001 ; t =9.234,P ＜ 0.001 ).The error number of of the neutral and negative- related words of the patients ( ( 3.70 ± 2.56) time,( 4.23 ± 2.53 ) time)was worse than that of HC group( ( 2.11 ± 1.87 ) time,( 1.92 ± 1.82 ) time) ( t =2.939,P =0.005 ; t =4.355,P ＜0.01 ).Error number of the alcohol- related words between two groups were not significant;Its alcohol-related words attentional bias negative correlation to the age of initial alcohol use(P＜ 0.05 ),and positive correlation to continue drinking and score of self-rating depression scale (P＜0.05).Age of addiction and the score of self-rating anxiety scale enter the regression equation of alcohol-related words.ConclusionThese results demonstrate that alcoholics have attentional bias in alcohol-related words and reward-related brain regions may be associated with craving among male patients with attentional bias.
ABSTRACT
Objective To evaluate the nutritional status in maintenance hemodialysis patients using objective score of nutrition on dialysis.Methods Patients on maintenance hemodialysis were randomly selected and divided into three groups based on objective score of nutrition on dialysis:normal nutritional status group,moderate nutritional status group,and low nutritional status group.Logistic regression analysis was performed to identify factors of malnutrition.Furthermore,the results were compared with those of subjective global assessment.Results Totally 75 patients(male:female =1.13∶1)with a mean age of(54.90 ± 12.10)years and a mean vintage of (85.37 ± 54.17)months were enrolled.As determined by objective score of nutrition on dialysis,15 patients (20％)were divided into normal nutritional status group,42(56％)into moderate nutritional status group,and 18(24％)into low nutritional status group.Compared with the normal nutritional status group,the low nutritional status group had significantly different body mass index[(19.81 ± 2.22)vs(23.90 ± 2.44)kg/m2,P =0.030]and dry weight[(50.85 ± 7.60)vs(59.94 ± 10.89)kg,P =0.020].In addition,compared with normal nutritional status group,the moderate nutritional status group and low nutritional status group had significantly different total cholesterol[(4.60 ± 0.84)and(3.73 ± 0.68)mmol/L vs(5.71 ± 1.64)mmol/L,P =0.011,P =0.000],normalized protein catabolic rate[1.17 and 1.15 g/(kg · d)vs 1.45 g/(kg · d),P =0.030,P =0.010],triceps skinfold thickness[(1.44±0.77)and(1.00±0.41)cmvs(1.80±0.63)cm,P=0.032,P=0.020],mid-ann circumference[(24.85±1.48)and(21.66±1.48)cmvs(24.99 ±2.30)cm,P=0.046,P =0.037].Logistic regression analysis indicated C-reactive protein(OR =12.482,95％ CI =0.190-130.928,P =0.035)and normalized protein catabolic rate(OR =0.128,95％ CI =0.022-0.736,P =0.021)were significantly correlated with malnutrition.Conclusion Malnutrition is common in hemodialysis patients,with inflammation and low protein intake being its independent factors.
