ABSTRACT
The BTB (broad-complex, tramtrack, and bric-à-brac) domain is a highly conserved protein interaction motif in eukaryotes. They are widely involved in transcriptional regulation, protein degradation and other processes. Recently, an increasing number of studies have shown that these genes play important roles in plant growth and development, biotic and abiotic stress processes. Here, we summarize the advances of these proteins ubiquitination-mediated development and abiotic stress responses in plants based on the protein structure, which may facilitate the study of this type of gene in plants.

ABSTRACT
Objective To observe the effects of transcranial magnetic stimulation combined with exercise training on fatigue and interleukin-1β (IL-1β),interleukin-9,interleukin-10,tumor necrosis factor-α and C-reactive protein (CRP) in patients with post-stroke fatigue (PSF).Methods A total of 90 patients with post-stroke fatigue were recruited and randomly divided into an observation group and a control group.Both groups were given routine exercise training,and the observation group was treated with transcranial magnetic stimulation in addition.Simplified Fugl-Meyer Motor Function Scale (FMA) and Fatigue Severity Scale (FSS) were used to assess the motor function of the limbs and fatigue of the two groups before treatment,4 and 8 weeks after treatment.At the same time,the levels of IL-1 β,IL-9,IL-10,TNF-α and CRP in the serum of the two groups were measured at the above time points.The correlation among the motor function,fatigue and cytokine levels was analyzed.Results There was no significant difference in the levels of IL-1β,IL-9,IL-10,TNF-α and CRP between the two groups before treatment (all P>0.05);FMA score and fatigue improvement in the observation group were significantly better than those in the control group after treatment for 4 and 8 weeks (all P<0.05);and serum levels of IL-1β,IL-9,IL-10,TNF-α and CRP in the observation group were significantly lower than those in the control group after treatment (all P<0.05).Pearson correlation analysis showed that FMA scores of limbs were negatively correlated with serum levels of IL-1β,IL-9,IL-10,TNF-α and CRP (P<0.05),and FSS scores were positively correlated with serum levels of IL-1β,IL-9,IL-10,TNF-α and CRP (P<0.05).Conclusion Transcranial magnetic stimulation combined with exercise therapy can significantly improve the motor function and ameliorate fatigue of PSF patients.The therapeutic mechanism may be related to the reduction of serum levels of IL-1β,IL-9,IL-10,TNF-α and CRP.
ABSTRACT
Objective To explore the direction value of endovascular pressure differences in endovascular management of subclavian steal syndrome (SSS).Methods Eleven SSS patients accepted endovascular management,admitted to our hospital from January 2016 to December 2017,were collected in this study.Before and after operation,pressure-sensing wire was used to measure endovascular pressure differences (mean distal stenosis pressure minus mean proximal pressure),digital substraction angiography (DSA) was used to assess the stenotic rate,transcranial doppler (TCD) was used to assess the steal degrees,and electronic sphygmomanometer was used to measure the systolic pressure differences between bilateral brachial arteries.The pressure differences before and after endovascular management were compared.Before operation,the relations of pressure differences with stenotic rate,steal degrees and systolic pressure differences between bilateral brachial arteries were analyzed.After operation,the relations of pressure differences with stealing and clinical symptom improvements were analyzed.The predictive values of pressure differences and residual stenosis in clinic success were compared.Results (1) After operation,the blood stealing disappeared and the clinical symptoms improved in 10 patients;although residual stenotic rate of one patient decreased obviously,blood stealing and clinical symptoms still existed after operation;the clinic success rate was 90.9%(10/11).(2) Pressure differences before surgery ([11.2±5.7] mmHg) were significantly higher as compared with those after the surgery ([2.5±5.3] mmHg,P<0.05).(3) Before operation,pressure differences were significantly correlated with stenotic rate (r=0.757,P=0.007) and bilateral systolic pressure differences (r=0.701,P=0.016).Six patients had pressure differences of 6-9 mmHg,enjoying degree I and Ⅱ of stealing,and 5 patients had pressure differences ≥ 10 mmHg,enjoying degree Ⅲ of stealing.(4) After operation,pressure difference was 18 mmHg in one patient without clinic success,but pressure differences were ≤ 3 mmHg in 10 patients with clinic success.(5) Significant difference was noted between the two clinic success indexes (residual stenotic rate ≤ 30% by DSA and pressure differences ≤ 3 mmHg,P<0.05).Conclusion Endovascular pressure differences can reflect the hemodynamic changes before and after endovascular management;as compared with residual stenosis,it is better to predict the clinic success after operation;it is useful to guide the endovascular management in the SSS patients.

Objective: To explore the clinical efficacy of ear acupuncture plus injection at Zusanli (ST 36) in treating shoulder pain after laparoscopic gynecological surgery, and to observe its effect on cytokines. Methods: Two hundred patients with shoulder pain after laparoscopic gynecological surgery were randomized into two groups based on their visiting sequence, 100 cases each. The observation group was intervened by ear acupuncture plus injection at Zusanli (ST 36), and the control group was intervened by oral administration of Ibuprofen, 10 d as a treatment course. The clinical efficacies of the two groups were compared after 2 treatment courses; the visual analogue scale (VAS), present pain intensity (PPI) and 36-item short-form health survey (SF-36) were measured before and after the treatment;the changes of interleukin (IL)-6 and IL-10 after the treatment were also observed. Results: The VAS and PPI scores were significantly changed after the treatment in both groups (both P<0.01). After the treatment, the VAS score in the observation group was significantly different from that in the control group (P<0.05). The component scores of SF-36 were significantly changed after the treatment in both groups (P<0.01); after the treatment, the scores of physical functioning (PF), bodily pain (BP), social functioning (SF), and mental health (MH) in the observation group were significantly different from those in the control group (all P<0.05). The contents of IL-6 and IL-10 dropped significantly after the intervention in both groups (both P<0.01), and the between-group differences were also statistically significant (both P<0.01). The total effective rate of the observation group was higher than that of the control group (P<0.05). Conclusion: Ear acupuncture plus injection at Zusanli (ST 36) can significantly improve the shoulder pain after laparoscopic gynecological surgery, down-regulate the expressions of IL-6 and IL-10, and boost the recovery.

ABSTRACT
ObjectiveTo compare the effects of preventative intra-aortic balloon pump (IABP) insertion with intra-or post-operative IABP insertion in high-risk patients undergoing coronary artery bypass grafting (CABG).MethodsFrom Jan 2008 to May 2011,one hundred and four patients received CABG or off-pump CABG (OPCABG) and IABP therapy in our hospital.The enrolled criteria of IABP insertion included left ventricular ejection fraction (EF) less than 0.40,unstable angina,AMI,left main stenosis,emergency CABG,refractory ventricular arrhythmia.Group1 included thirty eight patients with preoperative IABP insertion,thirty one for intra-operative IABP insertion ( group 2 ) and thirty four for postoperative IABP insertion ( group 3 ).The indications for IABP insertion for group 2 and 3 were unstable hemodynamics,failure to wean off cardiopulmonary bypass and low output syndrome during or after operation.Clinical data including operative mortality,ventricular fibrillation,chest drainage,hospital stay,ICU stay,ventilator supporting time,IABP supporting time,EF improvement rate,mechanical assist device and Inotropic drugs utilizations were analyzed among three groups.ResultsGroup 1 demonstrated good therapeutic results.There were significant statistic differences in operative mortality ( group 1 2.6%,group 2 12.9%,Group 3 47.1%),hospital stay[group 1 (23.6 ± 9.8) days,group 2 (21.5 ±9.7) days,group 3 (28.9 ±13.3) days],ICU stay[group 1 (2.3 ± 1.1 ) days,group 2 (3.5 ± 1.5 ) days,group 3 (5.2 ± 3.4) days],ventilator supporting time [group 1 (29.5 ± 23.0) hours,group 2 (38.7 ± 20.6) hours,group 3 (84.1 ± 48.0) hours],IABP supporting time [group 1 (77.0 ± 43.7 ) hours,group 2 ( 93.8 ± 44.8 ) hours,group 3 ( 121.5 ± 71.7 ) hours],EF improvement rate [group 1 (7.5 ± 7.2),group 2 ( 8.5 ± 7.5 ),group 3 (2.0 ± 6.7)],inotropic drugs utilization[group 1 ( 3.7 ± 4.9) days,group2 (6.2±4.6) days,group3 (10.8±5.4) days](P<0.05).ConclusionComparing with intra- or post-operative IABP insertion,high-risk patients undergoing CABG could significantly benefit from preventative IABP insertion.Early IABP insertion was recommended for high-risk patients undergoing coronary artery bypass grafting.
ABSTRACT
ObjectiveTo analyze whether association of edge to edge valve repair to artificial ring annuloplasty would result in better results in patients with severe tricuspid regurgitation (TR).MethodsFrom April,2001 to May,2010,41 patients underwent tricuspid valve repair to treat severe TR were studied.Twenty-one patients were done artificial ring annuloplasty alone (group R) and twenty patients were done artificial ring annuloplasty associated with edge to edge valve repair ( group E).All the patients received echocardiography before surgery,before discharge and in mid and long-term follow-up.The ratio between TR jet area (TRA) and right atrial area (RAA) was used to quantitatively evaluate the seriousness of TR.Movement of tricuspid valve leaflets,tricuspid valve orifice area,pulmonary artery pressure ( PAP),left ventricular ejection fraction ( LVEF) were obserbed to evaluate heart function.ResultsAt discharge in group R,no or trivial TR was presented in 7 patients,mild TR in 12 patients and moderate TR in 2 patient.Bad apposition of the free edges of anterior and septal leaflets was observed in paients with mild and moderate TR.While in group E,no or trivial TR was presented in 13 patients and mild TR in 7 patients.The follow-up ranged from 6 months to 100 months[average (54.8 ±26.7) months].In group R,no or trivial TR was present in 5 patients,mild TR in 11 patients,moderate TR in 4 patients and severe in 1 patient.Bad apposition of the free edges of anterior and septal leaflets was observed in paients with mild to severe TR.Redo tricuspid valve repair was done in one patient in group R for recurrent severe TR and the edge-to-edge valve repair was utilized.In group E,no tricuspid stenosis was found.No or trivial TR was presented in 10 patients,mild TR in 9 patients and moderate TR in 1 patient.The ratio of TRA/RAA of group R was significantly higher than that of group E (0.25 ±0.16 vs.0.13±0.10,P < 0.01).ConclusionAssociation of edge-to-edge valve technique to artificial ring annuloplasty was safe and effective for treatment of severe tricuspid regurgitation due to bad apposition of free edges of tricuspid leaflets and dilatation of tricuspid annulus,.It could decrease the incidence of residual tricuspid regurgitation and prevent the recurrence of severe tricuspid regurgitation.

ABSTRACT
Objective To analysis of risk factors for left atrial thrombosis in patients with rheumatic mitral stenosis.Methods From January 2001 to December 2008, 2277 patients with rheumatic mitral stenosis underwent operations in our hospital. There were 737 males and 1540 female, the age ranged from 19 to 84 years [average (50.9 ±10.2) years]. Left atrial thrombosis group (554 cases) and no thrombosis group (1723 cases) were divided, retrospectively collected data were analyzed with univariate and multivariate Logistic regression. Results 12 bvariables, including age, mitral valve orifice area, left atrial diameter, left ventricular diastole diameter, CRP, gender , degree of mitral stenosis, or regurgitation, degree of bicuspid regurgitation, degree of pulmonary hypertension, atrial fibrillation and heart function had statistic difference between two groups. With multivariate Logistic regression for these 12 factors, age, mitral valve orifice area, left atrial diameter, degree of mitral regurgitation and atrial fibrillation were found to be the affecting factors for left atrial thrombosis in patients with rheumatic mitral stenosis. Conclusion For patients with rheumatic mitral stenosis, age, mitral valve orifice area, left atrial diameter and atrial fibrillation are the risk factors for left atrial thrombosis. Mitral regurgitation is a protective factor for left atrial thrombosis.
ABSTRACT
Objective To evaluate the effectiveness of aspirin in preventing peripherally inserted central venous catheter (PICC) -related thrombosis. Methods Totally 360 cancer patients who had undergone routine PICC placement were equally randomized into aspirin group (receiving conventional PICC maintenance plus oral administration of aspirin; 100 mg/d, for consecutively 21 days) and control group (conventional PICC catheter maintenance). The incidences of phlebitis and thrombosis were observed in both two groups. Results The incidences of phlebitis and thrombosis were 3.3% and 0 in aspirin group, which were significantly lower than those in control group (8.9% , P = 0. 025; 1.7% , P = 0. 025). Conclusion The oral administration of aspirin after the PICC placement can reduce PICC-related thrombosis and phlebitis.
