Objective To systematically review the clinical efficacy of botulinum toxin A for the treatment of upper limb spasticity after stroke. Methods PubMed,EMbase,Cochrane Library,CBM, China National Knowledge Internet (CNKI),and Wanfang Data were retrieved by a computer. The randomized controlled trials and Case-control study of comparing botulinum toxin A combined with rehabilitation training and routine rehabilitation treatment for upper limb spasticity after stroke were collected. The retrieval time was from the foundation of the database to September 1,2016. At least two reviewers conducted literature screening,data extraction,and quality evaluation according to the inclusion and exclusion criteria. The Rev-Man 5. 3 software provided by the Cochrane Collaboration was used to conduct the Meta-analysis. Results A total of 356 articles were retrieved. Finally,11 articles met the inclusion criteria. The modified Jadad score showed that the scores of 9 articles were more than 4,which belonged to high-quality literature. Eleven articles included 614 patients,in which 316 were treated with botulinum toxin A. There were 298 patients in the control group. The results of Meta-analysis indicated that the Fugl-Meyer score (SMD =0. 94,95% CI 0. 75 to 1. 12),modified Ashworth score (SMD = - 1. 59,95% CI - 1. 78 to - 1. 40),and modified Barthel index (SMD = 0. 86,95% CI 0. 65 to 1. 08)in the botulinum toxin treatment group were superior to the control group. There were significant differences (all P < 0. 05). The incidence of adverse events (RR = 1. 06,95% CI 0. 78 to 1. 45)was similar in both groups. There was no significant difference (P > 0. 05). Conclusion The efficacy of treatment of upper limb spasticity after stroke with botulinum toxin A is exact,and the security is high. The appropriate rehabilitation training can effectively improve the limb motor function,muscle tension,and quality of life of patients.

OBJECTIVE: To observe the effect of lidocaine on respiratory failure and the airway peak pressure in patients with severe asthma. METHODS: The severe bronchial asthma patients treated with mechanical ventilation were randomly divided into treatment group and control group. The change in airway peak pressure, man-machine counteraction, and the correcting time of respiratory failure of the two groups were recorded. RESULTS: The average airway peak pressure was(41.18?10.66) cmH2O in the control group vs.(29.23?9.07) cmH2O in the treatment group; the incidence of man-machine counteraction was 100% for the control group vs. only 40% for the treatment group; the correcting time of respiratory failure was(6.42?1.73) h for the control group vs.(3.31?1.08) h for the treatment group. There were significant differences between the two groups in the above mentioned indexes(P

Objective To observe the clinical significance and laboratory diagnostic values of Pre-S1 antigens (Pre-S1)and its relativity to HBeAg and HBV-DNA after using interferon in association with kurarinone.Methods The content of Pre-S1 and HBV-M was detected by ELISA and the levels of HBV-DNA were detected by flores- cence quantitative PCR(FQ-PCR)in 100 serum samples of patients with HBV infection and patients after an antivi- ral treatment.Results Matched control in 50 serum of HBsAg-positive and detectable HBV-DNA cases,both 29 samples in 30 HBeAg-positive cases and 17 samples in 20 HBeAg-negative cases Pre-S1s were positive.Treatment set 50 serum of patients after taking two courses of an antiviral treatment for HBV infection,drawing blood to observe related markers,5 cases of effect set were turned into negative for serologic markers and virologic markers.19 cases of valid set,serologic markers were various and the HBV-DNA copies descended 2-3 orders of magnitude.26 cases of invalid set,serologic markers were not various,and 30 % samples of the HBV-DNA copies descended 1～2 orders of magnitude.Conclusion It was supplementary for Pre-S1 to indicate HBV expression when the HBeAg varied.It also provided detcctable laboratory markers in HBV infectivity,replication and therapeutic efficiency evaluation.

Aim To investigate the relationship be-tween the cardioprotection of apigenin ( Api ) from an-oxia/reoxygenation ( A/R) injury and Bcl-2 pathway. Methods H9 c2 cardiomyocytes were cultured and di-vided into normal control group, A/R group, Api pre-treatment group ( Api ) , Api + Bcl-2 inhibitor group ( Api + ABT-737 ) . Expression of Bcl-2 was deter-mined by Western blot,and cell viability was measured by MTT method. LDH, SOD, GSH-Px, MDA activity were determined by chromometry. ROS generation, mi-tochondrial membrane potential and apoptosis were de-termined by flow cytometry. Results 25h after apige-nin precondition,the expression of Bcl-2 was upregulat-ed in cardiomyocytes ( P <0. 01 ) . In the group pre-treated with 40 μmol · L-1 apigenin before A/R, the activity of LDH in culture medium decreased; the ac-tivity of intracellular SOD, GSH-Px increased; the content of MDA and ROS generation decreased; cell viability increased; mitochondrial membrane potential could be more stable and cell apoptosis decreased ( P<0. 01 ) . However, all these protective effects were attenuated significantly in the group pretreated with apigenin and Bcl-2 inhibitor ABT-737 . Conclusion The effect of apigenin against A/R injury in cardiomyo-cytes involves Bcl-2 pathway, and at least partly de-pends on its effect on upregulating the expression of Bcl-2 .

AIM: To discuss the clinical efficacy of fresh amniotic membrane ( AM ) during the microscopic adjustable suture surgery in children's intercommunity strabismus, in order to guide clinical treatment.
METHODS: With the clinical randomized control study (RCT), 60 (112 eyes) cases of patients in childhood who received microscopic strabismus surgery in our hospital were divided them into two different groups from Jan. 2010 to Oct. 2015. According to the application of AM on the basis of ophthalmology outpatient number, 30 cases (58 eyes) in group A were treated with rectus muscle recession surgery combined adjustable suture combined with AM. The other 30 cases (54 eyes) in group B were treated with rectus muscle recession surgery combined adjustable suture only. All patients in two groups were followed-up over 6mo after the strabismus surgery.
RESULTS:Twenty-seven cases ( 48 eyes ) of all the strabismus patients must be adjusted after strabismus surgery, and the eye position adjustment rate was 42.9%. At 1mo after surgery, eye position of 18 cases (29 eyes) can be adjusted in all patients, and 44. 8% (16 cases, 26 eyes ) in group A with the average of adjustment lengths was 2. 56±0. 64mm, and 5. 6% ( 2 cases, 3 eyes ) in group B, with the average of adjustment lengths was 0. 52±0. 28mm, the differences of the adjustment rate and the average of adjustment amount were both high statistically significant (χ2 =22.477, P<0. 01; t=16. 502, P<0. 01 ) between the two groups. Except of 3 cases who couldn't cooperate with eye position adjustment, they all received eye position adjustment in different degrees in one month after strabismus surgery,and after eye position adjustment, 27 cases (53 eyes) in group A got normal eye position, and the correction rate of eye position was 91. 4%, and 16 cases (28 eyes) in group B got normal eye position after eye position adjustment, the correction rate was 51. 9%, the differences of the correction rate were statistically significant (χ2=21. 827, P<0. 01) between the two groups.
CONCLUSION: The application of fresh AM in the microscopic adjustable suture strabismus surgery is exactly effective in treatment of children's intercommunity strabismus. It can significantly extend the adjustment time and increase the adjustment amount, and it also can statistically improve the controllability and achievement ratio for children's strabismus surgery.

Aim To investigate the damage of mitochondria in HUVECs cells by iron overload and the role of ADMA/eNOS/DDAHⅡ in it.Methods HUVECs cells were cultured and randomly divided into normal control (Ctrl) group, dextran iron (Iron) group and L-arginine (L-Arg) group.After 48 h, the survival rate of cells was detected by MTT assay;ADMA content and DDAHⅡactivity were measured by HPLC method;the expression of eNOS was determined by Western blot;LDH activity, MDA and NO content, and mitochondrial permeability transition pores(mPTP) openness were determined by colorimetric assay;ROS generation, mitochondrial membrane potential and apoptosis were determined by flow cytometry.Results After 48 h treatment with iron, the survival rate of HUVECs significantly decreased, while the activity of LDH in culture medium increased.The results showed that ADMA and MDA content significantly increased, NO content, DDAHⅡactivity, and the expression of eNOS markedly decreased, the generation of ROS was evidently elevated, mitochondrial membrane potential was lost apparently, mPTP openness was obvious, and the apoptosis of the HUVECs were worsened.However, as ADMA physiological antagonist, L-Arg significantly attenuated the above effects of iron.Conclusion Iron overload could damage mitochondrial function by eNOS and induce the apoptosis of HUVECs, in which ADMA/DDAHⅡ mechanism may also be engaged.

Objective To investigate the left ventricular (LV) torsion parameters of type B WolffParkinson-White syndrome (B-WPW) and to explore alternation of the left ventricular motion pattern in patients with B-WPW.Methods Thirty-eight patients with B-WPW were studied.And 40 volunteers were selected as control.Two-dimensional speckle tracking imaging (2D-STI) was used to acquire left ventricular torsion parameters,including peak value and time to peak value of LV twist,LV apex rotation,and LV base rotation.Apical-basal rotation delay (RDA-B) was calculated.Biplane Simpson method was used to measure LV end-diastolic volume (LVEDV),end-systolic volume (LVESV) and ejection fraction (LVEF).All above parameters were measured in patients with B-WPW before (B-WPW-B group) and after (B-WPW-A group) radiofrequency catheter ablation and in control group.The QRS width of lead Ⅱ was recorded,and the relationships between all above parameters with the RDA-B or QRS width were analyzed.Results Compared with the contrd group,in patients with B-WPW,the peak value of LV apex rotation (RotA),LV base rotation (RotB) and LV twist (TwistLV) were lower(LV base was more obvious than LV apex)(P ＜0.05),the time to RotB (TTPB) was shorter (P =0.004),RDAB was longer(P =0.002),the left ventricular enlarged and the QRS prolonged (P =0.000).After radiofrequency catheter ablation,the left ventricular torsion parameters in patients with B-WPW recovered significantly(P ＜0.05),but still lower than those in the control group(P ＜0.05).Conclusions The left ventricular motion pattern of patients with B-WPW alters,including the changes of peak value and time to peak value in LV apex rotation,LV base rotation and LV twist,as well as LV myocardium dyssynchrony.The motion pattern of LV in patients with B-WPW is improved in acute stage after radiofrequency catheter ablation but not yet recover totally.

Objective To analyze the differential expression of microRNA-146a (miR-146a) in monocyte-macrophage cell line (THP-1 cells) after induction by Cryptococcus neoformans (C.neoformans,reference strain WM148) or Cryptococcus gattii (C.gattii,reference strain R265),and investigate the mechanism of miR-146a in regulating the inflammatory response of cryptococcal meningitis.Methods The cultured THP-1 cells were divided into two groups to be induced by C.neoformans or C.gattii,respectively.THP-1 cells were induced with inactivated WN148 (or R265) strains at multiplicity of infection (MOI) of 5 in all experiments.The supematant and the cell pellet were collected separately after incubation.The expression of miR-146a was measured by real-time quantitative PCR (qRT-PCR) technique.The levels of TNF-u and IL-6 release were assayed by ELISA.Results The expression of miR-146a increased significantly in the C.neoformans induction group compared to 0 h.It reached peak at 3 h (P＜0.01),and then declined gradually.The level of TNF-α increased in supematant and reached peak at 12 h.The expression of IL-6 did not change significantly at each time point.The expression of miR-146a and TNF-α increased gradually and reached peak at 12 h in the C.gattii induction group (P ＜0.01),but the change did not reach statistical significance at 3 h,6 h time points.The expression of IL-6 gradually increased,and reached peak at 12 h time point.Conclusions Following stimulation with C.neoformans or C.gattii,the expression ofmiR-146a in THP-1 cells showed different patterns over time.The expression levels of TNF-α and IL-6 showed different patterns.These findings suggest that there may be different regulatory mechanisms in the THP-1 cells-associated inflammatory response after stimulation by inactivated C.neoformans and C.gattii strains.

AIM:To investigate the effects of seipin gene deficiency on renal injury and the possible mecha-nisms in seipin-/-mice.METHODS:Six-month-old male seipin knockout ( seipin-/-) and wild-type ( WT) mice ( n=8) were used to study 24 h urinary albumin excretion ( UAE) , renal functions, pathological changes, and plasma leptin and adiponectin levels.Seipin mRNA expression in different tissues and each part of the kidney was also measured in WT mice.RESULTS:Real-time PCR analysis showed seipin mRNA expression in WT mice was higher in adipose tissue and testicles, and was also found in the kidney, which was mainly in glomeruli.Compared with control group, seipin-/-group showed increased kidney weight/tibia length (P<0.01), 24 h UAE (P<0.01), creatinine clearance (P<0.01), and glomerular and mesangial surface area (P<0.05).Both plasma leptin (P<0.01) and adiponectin (P<0.05) levels were significantly decreased in seipin-/-mice.CONCLUSION:Seipin gene deficiency in mice leads to renal injury prob-ably by decreasing plasma leptin and adiponectin levels due to lack of adipose tissue.
