ABSTRACT

Objective:To explor the effects of mentalization-based family therapy (MBFT) on the emotions of anxiety and depression, reflective functions, and related brain regions of adolescents with depression.Methods:Thirty-two adolescent patients with depression were selected in Beijing Huilongguan Hospital.Among them, fifteen patients treated with conventional drugs were defined as the control group, the other seventeen patients served as the observation group.On the basis of routine drug treatment, patients in the observation group were treated with 1.5 h MBFT once a week, for a total of 3 months.Among them, 10 patients underwent resting functional magnetic resonance imaging(rs-fMRI) scans before and after the intervention.SPSS 23.0 was used for statistical analysis of scale evaluation data by using chi-square test and repeated-measure analysis of variance, and pairwise Pearson correlation was used to construct a brain network matrix for the MRI results.The patient's brain network matrix was put into Gretna to calculate, and then use repeated measures analysis of variance and t test for judgment. Results:(1)Repeated measurement analysis of variance showed, over time and group, before and after intervention, the group×time interactions of patients' reflective function, anxiety, depression were statistically significant ( F=5.113, 9.350, 5.264, all P<0.05). Further simple effect analysis showed, in the observation group, there were statistically significant differences in patients' anxiety ((55.09±14.35) vs (30.58±3.62)), depression ((61.58±16.81) vs (31.00±3.48)) before and after intervention (all P<0.01). There was no significant difference in reflective function ((8.71±0.51) vs (8.87±0.50) ) in the observation group before and after intervention( P> 0.05). The reflective function((8.92±0.33) vs (8.73±0.35)) and anxiety((50.67±13.88) vs (45.78±12.89)) scores of the control group were not statistically significant different before and after intervention(all P>0.05), and the depression scores of the control group before and after inter-vention((69.33±9.11) vs (50.94±7.99)) were statistically significant different( P<0.01). (2)rs-fMRI showed that, using the posterior parietal lobe and the medial prefrontal lobe as seed points, the group×time interactions with right inferior frontal gyrus, right fusiform gyrus, right superior temporal gyrus, left middle temporal gyrus and right superior frontal gyrus were statistically significant ( F=29.56, 20.63, 8.69, 9.49, 8.62, all P<0.05). The further simple effect analysis showed in the observation group, the pre-test was less than the post-test, and the difference was statistically significant( P<0.05). In the control group, there were not statistically significant differences in the functional connection strength before and after the test(all P>0.05). (3)The brain network analysis of 264 regions of interest (ROIs) in the whole brain showed that the number of modules in the observation group was less than that in the control group, and the difference was statistically significant ( t=-2.64, P=0.046). Conclusion:MBFT can improve the anxiety and depression of adolescent patients with depression.It enhances the functional link between mentalization related brain regions and the whole brain, and enhances the activity of the whole brain link to become more integrated.

ABSTRACT

Delirium is a common complication in elderly inpatients which could result in cognitive impairment, and increase the risk of disability, fall and mortality. Moreover, it could cause heavy social burden. Even with multiple bedside screening scales to detect delirium, the rate of missed diagnosis is still high. Maybe it is associated with the acute fluctuation and nocturnal onset of delirium. With the development of the intelligence and automation of the electronic medical record (EMR), previous studies have explored the use of EMR to identify delirium patients, and this method provides help for delirium diagnosis and prevention. In this paper, we reviewed and summarized the current situation of research on delirium recognition by EMR, and put forward the development prospect in this method in order to provide basis and lay a foundation for intelligent diagnosis of delirium.

ABSTRACT

Objective: To establish an intensity-classified Chinese facial emotion image database and provide materials for emotional researches in China. Methods: Firstly, under the guidance of professional director, 22 professional dramatic actors put up seven kinds of emotion, including anger, disgust, fear, sadness, surprise, happy and calm. The process of facial emotional performance of actors were filmed by a high-speed camera. Then we made screen captures according to the intensity of emotion performed by the actors. A total of 814 black-and-white photographs with same size and gray level were made after we removed the irrelevant parts to the facial features. Each kind of emotion contains six levels of intensity scoring from 1 to 6. Totally, 112 healthy volunteers were recruited to evaluate the emotional intensity, pleasure and arousal of all images via a visual scale ranged from 0 to 100. Results: A Chinese face emotional intensity hierarchical picture library was set up, which contained 2 sublibraries. The first library was consisted of 436 images with hierarchical emotional intensity images collected from different performers. The second one was built with 640 images, in which the hierarchical emotional intensity image was collected from same actor/actress. Both image libraries had corresponding scores for intensity, pleasure, and arousal. Furthermore, both exhibited a high degree of internal consistency in reliability analysis (with a Cronbach' s alpha value larger than 0. 9). Conclusion: The present study has established an intensity-classified Chinese facial emotion image database with good recognition degree and psychological measurement attribution, which could provide materials for emotional researches in China.

ABSTRACT

Objective@#To analyze the clinical characteristics and prognosis of 34 cases of acute myeloid leukemia (AML) with FLT3 internal tandem duplication (FLT3-ITD) and MLL gene rearrangement.@*Methods@#The clinical data of 34 AML patients with FLT3-ITD and MLL gene rearrangement was compared and analyzed for the therapeutic efficacy, prognostic factors when treated with chemotherapy, chemotherapy combined with targeted therapy or allogenic hematopoietic stem cell transplantation (allo-HSCT).@*Results@#Of the thirty-four cases with median age 41 (4-71) years old, 63.6% presented with white blood cells (WBC) greater than 30×109/L, 39.4% greater than 50 × 109/L respectively on admission. M5 (35.3%) made up the highest proportion. The cytogenetic abnormality reached 61.8%, of which the complex cytogenetic abnormality accounted for 11.8%. Eleven patients (32.35%) had both FLT3-ITD and MLL gene abnormalities. In addition to FLT3 and MLL abnormalities, 23 patients (67.6%) had one or more other gene abnormalities (multiple gene abnormalities). Of the 34 cases, 29.4% patients went into complete remission (CR) after two courses of chemotherapy. 20.6% (7 patients) went into CR after 3 or more courses of chemotherapy. The rate of early relapse in the CR group was 52.9%. Patients with WBC>50×109/L or multiple gene abnormalities had a lower remission rate (7.7%, 5.4%) after two courses of chemotherapy. CR rate for the patients with more than three gene abnormalities was 0. The total 2-year overall survival (OS) in the 34 patients was 28.8% (95% CI 13.5%-46.0%) and the disease-free survival (DFS) was 27.1% (95% CI 12.5%-44.0%). Of the 18 patients treated with chemotherapy alone or chemotherapy combined with targeted therapy, 17 cases died within 2 years and 1 lost follow-up after giving up treatment. For the 16 patients received allo-HSCT, the 3-year OS was 43.4% (95% CI 13.7%-70.4%) and DFS 42.7% (95% CI 13.4%-69.7%).@*Conclusion@#AML patients with FLT3-ITD and MLL gene rearrangement often presented with M5, accompanied by hyperleukocytosis, cytogenetic or multiple gene abnormalities. Those patients were observed to have low response rate and high early relapse when treated with chemotherapy without allo-HSCT. Patients had multiple gene abnormalities may be an important poor prognostic factor. Allo-HSCT is an effective treatment which could significantly improve the prognosis and survival of AML patients with FLT3-ITD and MLL gene abnormalities.

ABSTRACT

Aim To examine the influence of tetramethylpyrazine on learning and memory function of hypoxic hypoxia rats, and the expression of gamma aminobutyric acid(GABA) receptor and forkhead box P2(FOXP2) in hippocampus of rats.Methods A total of 120 Sprague Dawley rats were randomly divided into low hypoxic hypoxia and high hypoxic hypoxia groups, then according to different time points every group was divided into 1 d, 3 d, 7 d 15 d, 30 d group, with 12 rats per each group.Experiment group and the control group were treated with tetramethylpyrazine and 0.9% normal saline, respectively.The hypoxic hypoxia environment was achieved by putting the rats in a hypobaric chamber at a simulated altitude of 5 500 meters for different days.The capabilities of learning and memory of rats were detected by Morris water maze test.The expression of GABA receptor and FOXP2 protein in hippocampus of rat was determined by Western blot.Results ① Morris water maze test showed that the total distance of rats in the simulated hypobaric hypoxia control group was longer than that in the tetramethylpyrazine group(P0.05);however,GABAB1 receptor and FOXP2 protein rose from the third day(P<0.05).The expression of GABAAα1 receptor and FOXP2 protein expression were correlated to total distance of Morris water maze in the control group(r=-0.738, P<0.05;r=-0.693, P<0.05), and the expression of GABAB1 receptor was correlated with FOXP2 protein level(r=0.834, P<0.05).Conclusion The simulated high-altitude hypobaric hypoxia can decrease the learning and memory abilities of rats, which may be ameliorated by tetramethylpyrazine intervention, and this effect might be related to the increase of GABAB1R receptor and FOXP2 expression in hippocampus of rats.

ABSTRACT

Objective@#To investigate three different types of donor hematopoietic stem cell transplantation (HSCT) for intermediate and high-risk myelodysplastic syndrome (MDS) .@*Methods@#Between August 2001 and May 2015, 167 consecutive patients with MDS in intermediate and high-risk who underwent allogeneic HSCT were analyzed retrospectively.@*Results@#With the median follow up of 60 (12-177) months, The total 5-year DFS was 67.8% (95%CI 60.0%-75.6%) . Among three different types of donor, 5-year DFS rates were 68.0% (95%CI 54.1%-81.9%) in MSD-HSCT vs 77.4% (95%CI 62.1%-92.7%) in MUD-HSCT vs 64.0% (95% CI 52.4%-75.6%) in Haplo-HSCT (P=0.632) , respectively. Univariate analysis showed that median disease course before HSCT was the influencing factor of DFS (P=0.018) . Five-year relapse and TRM had no correlation with the above-mentioned factor.@*Conclusions@#Haplo-HSCT for intermediate and high-risk MDS achieved similar effect produced by MUD or MSD, Haplo-HSCT could be used as an important alternative donor. allo-HSCT must be performed on intermediate and high-risk MDS patients as early as possible after diagnosis.

ABSTRACT

Objective@#To investigate the effect of minimal residual disease (MRD) monitoring by multiparameter flow cytometry (MFC) pre-conditioning on prognosis of acute myeloid leukemia in first complete remission (CR1-AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) , and to explore the value of MRD monitoring by MFC in the prognosis evaluation on allo-HSCT in CR1-AML.@*Methods@#Between April 2012 and March 2015, consecutive 186 patients with CR1-AML who underwent allo-HSCT were analyzed retrospectively. MRD in BM before conditioning was detected by eight-color MFC. Any level of residual disease was considered to be MRD positive.@*Results@#①Of 186 patients, MRD was negative in 151 patients, positive in 35 patients (<1% in 25 patients and 1% to 3% in 10 patients) . ② With the median follow up of 18 (5-41) months, two-year DFS was 80.0% (95%CI 68.5%-92.3%) . Univariate analysis showed that MRD positive patients had lower DFS[62.9% (95%CI 50.6%-75.2%) vs 88.9% (95%CI 76.6%-100.0%) , P<0.001], higher relapse[11.4% (95%CI 4.1%-29.0%) vs 3.3% (95% CI 0.6%-20.9%) , P=0.003] and higher NRM [25.7% (95% CI 8.1%-43.3%) vs 7.9% (95% CI 1.3%-26.5%) , P=0.001] after HSCT compared with that of MRD negative patients. Secondary AML showed lower DFS than primary AML [60.0% (95% CI 42.4%-76.6%) vs 86.0% (95% CI 68.4%-100.0%) , P=0.004]. ③Multivariate analysis indicated that MRD positive pre-HSCT was the independent risk factor on DFS [HR=4.565 (95%CI 2.918-9.482) , P<0.001], relapse [HR=5.854 (95%CI 1.538-22.288) , P=0.010] and NRM [HR=3.379 (95%CI 1.361-8.391) , P=0.009] after allo-HSCT in CR1-AML.@*Conclusion@#MRD positive pre-conditioning was the only negative impact factor for patients with CR1-AML after allo-HSCT. MRD by MFC can be used to assess the prognosis of CR1-AML after allo-HSCT.

ABSTRACT

Objective@#To analyze the effect of NCCN (2015) risk stratification on prognosis of patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .@*Methods@#Retrospective analysis of 258 patients with AML in CR (186 cases in CR1, 72 cases in CR2) who underwent allogeneic HSCT in our hospital between April 2012 and March 2015 according to NCCN (2015) risk stratification. Of them, 63 cases were classified as low risk, 112 cases intermediate risk and 83 cases high risk.@*Results@#①With the median follow up of 18 (5-41) months, two-year disease free surviva (DFS) in 258 patients was 78.0% (95% CI 60.4%-96.6%) . Two-year DFS in AML after transplantation was 78.6% (95% CI 61.0%-96.2%) in low risk, 76.0% (95% CI 84.0%-93.6%) in intermediate risk and 80.3% (95% CI 62.7%-97.9%) (P=0.886) in high risk groups respectively. ②Univariate analysis showed that DFS has no significant difference in patient age, the median disease course before HSCT, the WBC number at the beginning of the disease, blood routine and chromosomes examination before transplantation, extramedullary disease before transplantation, disease status before transplantation, conditioning regimen, donor type, donor and recipient sex, recipient blood type, transfused MNC number, transfused CD34+ cell number and transfused CD3+ cell number. DFS was significant lower in primary AML than that in secondary AML (P=0.006) and also lower in MRD positive than that in MRD negative (P=0.003) . The accumulative relapse was significant higher in CR2 compared to that in CR1 (P=0.046) . Accumulative non-relapse mortality (NRM) was significanlyt higher in secondary AML compared to that in primary AML (P=0.004) and also higher in MRD positive compared to that in MRD negative (P=0.010) . ③Multivariate analysis showed that MRD positive was the only significant factor in DFS and NRM.@*Conclusion@#Allo-HSCT treatment of AML CR patients could achieve a high efficacy, which is similar between CR1 and CR2 patients. There is no significant correlation between NCCN (2015) risk stratification and the prognosis of AML patients with allo-HSCT treatment. Pre-conditioning MRD status monitored by multiparameter flow cytometry was the only impact factor on DFS and NRM in allo-HSCT for CR-AML patients.

ABSTRACT

Aim To observe the effects of glucose-stim-ulated insulin secretion ( GSIS ) on rat islets after S1 P treatments and the underlying molecular mechanisms. Methods Collagenase P and Histopaque 1077 were used to digest and isolate rat pancreatic islets, and Dispase II was used to digest pancreatic islet to obtain pancreatic cells. Insulin secretions were measured after S1P (0~20 μmol·L-1 ) treatment under low glucose ( LG, 2. 8 mmol·L-1 ) and high glucose ( HG, 16. 7 mmol·L-1 ) conditions. Patch-clamp recordings were applied to monitor voltage-dependent potassium chan-nel currents (Kv currents) after S1P treatment. Calci-um image technique was used to measure the changes of intracellular Ca2+ concentration after S1P ( 0 ~20μmol·L-1 ) treatments. Results HG group signifi-cantly increased insulin secretion compared to LG group ( P0. 05 ) . S1 P increased insulin secretion significantly in a dose-dependent man-ner under HG condition ( P<0. 01 ) . Kv currents ofβcells were inhibited significantly after S1 P treatment ( P<0. 01 ) . S1 P increased the concentrations of in-tracellular Ca2+ in a dose-dependent manner under HG condition( P <0. 01) . Conclusion S1P may pro-mote GSIS by inhibiting Kv currents and increasing the level of intracellular Ca2+.

ABSTRACT

BACKGROUND:Tumor stem cels are the root of cancer recurrence and metastasis, so clinical researches should focus on the effects of different treatments on tumor stem cels. OBJECTIVE:To explore the effects of endocrine therapy and chemotherapy on stem cels in patients with breast cancer. METHODS:After recovery and cultivation of estrogen receptor-positive human breast cancer cel lines MCF-7, passage 3 cels in logarithmic phase were selected and divided into three groups containing control, estradiol and estradiol with tamoxifen groups. The estradiol group was divided into three subgroups: 10-7, 10-8 and 10-9 mol/L estradiol was added into the medium, respectively; the estradiol with tamoxifen group was divided into three subgroups: 10-7, 10-8 and 10-9 mol/L estradiol with 10-6 mol/L tamoxifen were added into the medium, respectively. The same amount of absolute ethyl ethanol was added into the medium of control group. Fifteen female patients with late recurrence and metastasis of breast cancer received chemotherapy as recurrence and metastasis group. Another 15 healthy volunteers were selected as healthy control group. RESULTS AND CONCLUSION:The proportion of CD44+CD24-/lowcel subsets in the estradiol and estradiol with tamoxifen groups was significantly higher than that of the control group (P < 0.05), and the proportion of CD44+CD24-/low cel subsets in the estradiol group was significantly higher than that of the estradiol with tamoxifen group at the same concentration (P< 0.05). The proportion of CD44+CD24-/lowcel subsets had no significant differences among groups at 10 and 20 days of culture (P < 0.05). The proportion of CD44+CD24-/low cel subsets significantly increased in MCF-7 cels after 24-hour intervention with different chemotherapy drugs. But only the proportion of CD44+CD24-/low cel subsets in the paclitaxel and doxorubicin groups was significantly higher than that of the control group after 20-day intervention (P < 0.05). Besides, the proportion of CD44+CD24-/low cel subsets in the peripheral blood of healthy volunteers was significantly lower than that of the recurrence and metastasis group (P < 0.05). Among 15 patients with late recurrence and metastatic of breast cancer, 9 had stable disease, 5 had partial remission, 1 had failed chemotherapy and cancer progression. Moreover, the proportion of CD45-CD44+CD24-/low cel subsets in the peripheral blood of patients sensitive for chemotherapy was significantly lower than that before treatment (P < 0.05). In conclusion, both endocrine therapy and chemotherapy exert a certain effect on the CD44+CD24-/low cel subsets of breast cancer positive for estrogen receptor. Given that CD44+CD24-/low cel subsets in MCF-7 cels resist chemotherapy drugs, the proportion of CD45-CD44+CD24-/low cels in the peripheral blood of patients sensitive for chemotherapy is decreased.

ABSTRACT

Objective To investigate the effects of dexmedetomidine on plasma IL-8,IL-10 level and lung AQP1 expression in patients undergoing one lung ventilation(OLV).Methods Forty patients,ASA Ⅰ or Ⅱ,scheduled for lung cancer radical surgery were randomly divided into two groups:control group (group C)and dexmedetomidine group (group D).In group D,dexmedetomi-dine 1 μg/kg (initial dose)was given over more than 10 min before anaesthesia induction,followed by continuous infusion at 0.5 μg·kg-1 ·h-1 until 30 min before the end of operation.In group C,the e-qual volume of normal saline was infused.Blood samples were collected at immediately before OLV (T1 ),30 (T2 ),60 (T3 ),120 (T4 )min of OLV,30 min after lung inflate (T5 )and 2 h after opera-tion (T6 )for determination of plasma IL-8 and IL-10 levels.Lung tissues were obtained at T1 for de-termination of AQP1 expression.Results Compared with the value at T1 ,plasma IL-8 levels in group C at T3-T6 and in group D at T3-T5 were increased,plasma IL-10 levels were increased in both groups at T2-T5 (P <0.05).Compared with group C,plasma IL-8 levels at T3-T6 were decreased and plasma IL-10 levels at T2-T5 were increased in group D (P <0.05).Compared with the value at immediately before OLV,the expression of AQP1 was decreased at the time of lobectomy of lungs in group C (P<0.05).Compared with group C,the expression of AQP1 at the time of lobectomy of lungs in group D was increased (P <0.05).Conclusion Dexmedetomidine 1 μg/kg followed by continuous infusion at 0.5 μg·kg-1 ·h-1 can reduce inflammatory response,up-regulate the expression of AQP1 in pa-tients undergoing OLV.

ABSTRACT

Feline calicivirus (FCV) is an important and highly prevalent pathogen of cats that causes feline respiratory disease. The reverse genetic systems for FCV have been established in national and international laboratories since 1995. This technique has been used widely in FCV basic research and good progress has consequently been made to determine the relationship between viral genome structures and the function of their proteins, the expression of foreign proteins, virus-host interactions, and viral pathogenic mechanisms. In this article,we review the state of progress with regards to the establishment and application of the FCV reverse genetic operating system,which will provide a useful reference tool for future related research.
