ABSTRACT
ObjectiveTo analyze the effectiveness and safety of clinical use of different types of stem cells to provide evidence for governmental supervision of key issues in clinical utilization of stem cells. MethodsSix literature databases in China and abroad were searched for relevant literature published from January 2010 to July 2020， and a systematic review was conducted. ResultsThe study showed 72 studies concerning the effectiveness and safety of different types of stem cells in clinical utilization. Although clinical utilization of stem cells had some therapeutic effects for certain diseases， their long-term effect and safety need to be further evaluated， especially their potential risk of tumorigenicity. ConclusionTo protect the patients’ interest， physicians should fully weigh the benefits against the risks of clinical utilization of stem cells， and relevant governmental departments should strengthen supervision of ethics of clinical research and therapies involving stem cells as well as supervision of stem cell products.
ABSTRACT
Objective:To explore the characteristics of eye tracking movement on circumscribed interests in preschool children with autism spectrum disorder (ASD), providing some reference for behavior correction and rehabilitation training.Methods:Fifty ASD children and fifty-two age-matched typically developing children(TDC) were investigated by the childhood autism rating scale(CARS), the autism diagnostic observation schedule(ADOS), the autism diagnostic interview-revised (ADI-R) and Gesell Developmental Schedule, (GDS). Eye movement during the visual search task was captured by the Tobii Pro X3-120 eye tracker.All data were analyzed by the IBM SPSS Statistics 20.0.Eye movement patterns were compared between TDC and ASD children using the independent-sample t test, and the correlations were then analyzed between abnormal eye movement characteristics and their core syndrome. Results:The total scores of CARS, ADOS and ADI-R in ASD group were 34.13±4.59, 14.44±2.59 and 39.91±12.11 respectively.During passive viewing of complex non-social picture arrays, ASD and TDC group explored total number of images were 9.28±2.72 and 12.67±2.45.The fixation time per image explored in ASD and TDC group were (0.67±0.37)ms and (0.54±0.15)ms.Moreover, the number of discrete fixations per image explored in ASD and TDC group was 2.80±1.00 and 2.48±0.48.Compared with the TDC group, ASD children demonstrated circumscribed attention ( t=6.610, P<0.01) with more perseveration ( t=-2.363, P=0.021) and detail-orientation ( t=-2.360, P=0.021). Exploration was negatively correlated with the total score of ADOS ( r=-0.480, P<0.01), CARS ( r=-0.487, P<0.01), communication score of ADOS( r=-0.290, P=0.041), social score of ADOS( r=-0.491, P<0.01), game score of ADOS( r=-0.397, P=0.004)and communication score of ADI-R( r=-0.331, P=0.025)in the ASD group. Conclusion:Compared with TDC, the eye movement pattern shows the circumscribed interests of ASD children, who not only explore fewer objects but also demonstrate circumscribed attention with more perseveration and detail-orientation.Moreover, the more severe the symptoms of ASD children, the fewer objects the children explore and the more stereotyped the circumscribed interest.

ABSTRACT
Objective To randomly compare the therapeutic effect and safety between Levetiracetam (LEV) and Phenobarbital (PB) in the treatment of neonatal seizures.Methods A total of 61 infants with acute convulsion were randomly divided into 2 groups:LEV group (n =30) and PB group (n =31) during January 2013 to December 2014 in Urumqi Children's Hospital.All neonates received routine management including etiology treatment and adverse drug reaction monitoring.In the LEV group,subjects received oral formulation of LEV with initial loading dose 30 mg/kg,followed by 15 mg/kg twice a day.If the seizures were not controlled completely,PB treatment was added until seizures were completed controlled.If seizures were controlled quickly,the dose of PB was gradually reduced and LEV was used as monotherapy.The subjects in PB group received intramuscular or intravenous injection of PB with 10 mg/kg as the first dose,then 5 mg/(kg · d) oral PB was administered,if seizures were not controlled,LEV treatment was added,then dose of PB was gradually reduced until seizures were controlled completely,and then patients were switched to LEV monotherapy gradually.The drug adverse reactions were observed.Results (1) After LEV or PB monotherapy,66.7％ (20/30 cases) and 54.8％ (17/31 cases) of the subjects obtained sustainable seizure free respectively.Although,there was a higher control ratio in LEV group,but no significant difference was observed between the 2 groups (P ＞0.05).(2) LEV group (16/30 cases,53.33％) had higher rapid seizure control ratio with seizure controlled within 24 h after first dosage administration than that of PB group (8/31 cases,25.80％),and there was significant difference (x2 =4.841,P =0.028).Further more,if adding the cases who had to change to use another comparative one (LEV or PB) due to their seizures failure control with the first one treated,LEV group (21/44 cases,47.72％) still had higher rapid seizure control ratio in total patients than that of PB group(10/41 cases,24.39％),and there was significant difference (x2 =4.988,P =0.026).(3) Eight cases who changed to LEV after PB as the first treatment drug failed obtained sustainable seizure free.(4) One case in PB group with transient urinary retention was observed but the symptom disappeared 36 h after PB withdrawal,and no significant drug adverse reaction was observed in LEV group.Conclusion LEV is more rapid and safe for seizure control of neonates than PB.
ABSTRACT
Objective To evaluate the guidance value of VKORC1 and CYP2C9 gene polymorphism on clinical application of warfarin in patients with non-valvular atrial fibrillation (NVAF). Methods A total of 290 cases of patients with NVAF were identified and their baseline data , initial dose of warfarin and base INR measurement results were recorded, then the follow-up was conducted. The initial administration of warfarin to INR standard time for the first time, total amount of warfarin and the average daily amount were recorded. All participants′ venous blood was extracted for VKORC1 and CYP2C9 gene polymorphism test. Results VKORC1 AG/GG genotype patients had longer INR standard time and higer amount of warfarin than patients with AA (103.38 ± 65.29)g vs. (53.26 ± 24.02)g, P < 0.05. Patients with type CYP2C9 gene mutation had shortest INR standard time(9.10 ± 2.01)d vs. (13.07 ± 4.28)d, P < 0.05. and lowest administration amount of warfarin (28.80 ± 17.35)g vs. (55.45 ± 23.67)g, P < 0.05. Conclusion There exist significant differences of first adminstration amount of warfarin in patients with NVAF to INR standards. Warfarin dose for VKORC1 AA genotype patients is lower than that for GG/AG type; there is short INR standard time and less adminstration amount of warfarin for CYP2C9 genotypes AC/CC patients.
ABSTRACT
Objective To investigate the relationship of serum IL-6 levels with cognitive dysfunction among patients with obstructive sleep apnoea syndrome (OSAS).Methods Patients diagnosed with OSAS by polysomnography (PSG) received assessment of cognitive function with Montreal Congnitive Assessment (MoCA).According to the result of MoCA assessment,patients were divided into two groups,without cognitive dysfunction group (n =47) and with cognitive dysfunction group (n =55);30 health volunteers were used as control.Serum IL-6 levels were detected by enzyme-linked immunosorbent assay (ELISA) in three groups;according to the apnea hypopnea index (AHI),OSAS patients with cognitive dysfunction were divided into three groups,light group (n =15),moderate group (n =16),and severe group (n =24),and differences in MoCA scores and serum IL-6 levels were analyzed among three groups.The correlation of serum IL-6 levels and MoCA scores were analyzed in OSAS patients with cognitive dysfunction.Results Serum levels of IL-6 in OSAS patients with cognitive dysfunction [(197.3 ± 72.58) pg/ ml] were significantly increased than those without cognitive dysfunction [(155 ± 39.3)pg/ml] as well as health control [(87.39 ±33.44)pg/ml] (P ＜0.01).For OSAS patients with cognitive dysfunction,MoCA scores were decreased and the level of serum IL-6 was increased among patients with poor AHI grade,with statistically significant difference.Pearson correlation analysis showed serum IL-6 levels were significantly negatively correlated with MoCA scores among OSAS patients with cognitive dysfunction (r =-0.65,P ＜ 0.01).Conclusions Serum levels of IL-6 in OSAS patients with cognitive dysfunction were significandy increased and correlated with the cognitive dysfunction.OSAS patients with cognitive dysfunction experiencing sever AHI grade have more serious cognitive dysfunction and the higher serum levels of IL-6.
ABSTRACT
A rapid, reliable and sensitive pressurized capillary electrochromatography-Laser induced fluorescence ( pCEC/LIF ) method with trifluoroacetic acid ( TFA ) pre-column derivation for simultaneous determination of four aflatoxin ( AFB1 , AFB2 , AFG1 , AFG2 ) was developed. This method included separation on a capillary column packed with 1. 8μm C18 particles using 0. 05% FA aqueous solution/methanol (55:45, V/V) as mobile phase at a pump flow rate of 0. 05 mL/min when the split ratio was 1:300. Under the optimum conditions including running voltage of 15 kV, excitation wavelength of 375 nm and emission wavelength of 450 nm, the baseline separation of four aflatoxins was achieved within 10 minutes. The limits of detection (LODs) were 0. 02, 0. 016, 0. 008 and 0. 01 μg/L for AFG1, AFB1, AFG2, AFB2(S/N=3), respectively. The linear detection ranges of AFG1 , AFB1 , AFG2 , AFB2 were 0. 1-10, 0. 1-10, 0. 1-3 and 0. 1-3 μg/L with correlation coefficients (R2) of 0. 9999, 1. 0000, 0. 9995 and 0. 9997, respectively. The established method was applied to analyze the peanut butter, and the recoveries of standard addition experiment were between 90 . 0% and 112 . 0% for all analytes ( RSDs=0 . 5%-1 . 9%) .
ABSTRACT
Objective To explore the moderating and mediating roles of psychological capital in the associations of effort?reward imbalance and overcommitment with job burnout among iron?steel workers. Methods Totally 1 700 male iron?steel workers from an iron and steel company were enrolled for the study. A set of questionnaires that included demographic and working factors,the Maslach Burnout Inventory?General Survey,the Ef?fort?reward Imbalance Scale and the Psychological Capital Questionnaire,as well as perceived work environment was distributed to the subjects. A to?tal of 1 254 effective respondents(73.76%)were collected. Hierarchical linear regression analysis was performed to explore moderating role,and as?ymptotic and resampling strategies were used to detect mediating role. Results There was no moderating role of psychological capital on the associa?tion between effort?reward imbalance and job burnout. Psychological capital had significant and positive moderating roles on the associations of over?commitment with emotional exhaustion and cynicism. Psychological capital showed significant mediating role in the associations of effort?reward im?balance with emotional exhaustion and cynicism,and the proportion of mediating role was 5.84%and 18.75%,respectively. Conclusion In work?ers with high level of psychological capital,emotional exhaustion and cynicism would be significantly increased with overcommitment,and there is a weak increasing trend of emotional exhaustion and cynicism in workers with low level of psychological capital. Effort?reward imbalance could lead to emotional exhaustion and cynicism through the reduction of psychological capital of iron?steel workers.
ABSTRACT
Objective To investigate the efficacy and safety of Levertiracetam (LEV) in treating the neonates with intractable seizure, those who had under gone failed Phenobarbital (PB) treatment previously switched to or added LEV treatment currently.Methods Totally 14 neonates,designed as intractable seizure by clinical data and video electroencephalography(VEEG) and failed to PB treatment were enrolled in the study, and all neonates were switched to LEV or LEV + PB treatment.The initial loading dose of LEV was 30 mg/kg, followed by 15 mg/kg twice a day if symptoms were controlled 8-12 h,if not, followed by 30 mg/kg once.All neonates were switched to LEV monotherapy after the symptoms were controlled 48-72 h,if the symptoms could not be controlled by combined therapy of PB and LEV after 72 h, other therapies were administered.Electrocardiogram breath synchronous monitoring was performed during the first 72 h treatment.VEEG was performed during 1-3 months follow-up.Results (1) The symptoms of 8 (57.14％) out of 14 cases were completely controlled,2 neonates(14.29％) reduced seizure more than 50％ ,4 neonates(28.57％) failed to LEV or LEV + PB treatment,as a result,all of those neonates were switched to other treatments.(2) No drug adverse effect was observed.(3) One neonate died of hypoxic-ischemic encephalopathy combined with multiple organ failure during follow-up period, 7 cases were seizure-free with normal VEEG, 5 cases were switched to or added other antiepileptic drugs because of uncontrolled symptoms, and one neonate discontinued the follow-ups.Conclusions The high efficiency and safety of LEV for the treatment of the newborn seizures were proved by small samples of patients.And currently there is no evidence to prove PB might increase neuronal excessive apoptosis of the brain and the cognitive impairment, and more clinical researches are needed to promote LEV as a gleam of rescue medications of neonatal seizure as soon as possible.
