Outcomes of Eight‐Plate Epiphysiodesis for Residual Clubfoot Deformities

ObjectiveThe outcome of congenital clubfoot treatment is still challenging if the feet deformities are not completely corrected. Here we explore a minimal invasive procedure with an eight‐plate implant to correct the residual forefoot adduction deformity after treatment of neglected or relapsed clubfoot.MethodsWe retrospectively reviewed patients with residual forefoot adduction deformity after clubfoot treatment between January 2013 and June 2016. The patients underwent temporary epiphysiodesis of the lateral column of the mid‐foot, which in detail, an eight‐plate was placed on each side of the calcaneocuboid joint. The foot deformities were recorded according to the weight‐bearing radiographic measurements including talo‐first metatarsal angle, calcaneo‐fifth metatarsal angle and medial‐to‐lateral column length.ResultsA total of 13 patients (20 feet) with an average age of 7.8 years old were located with an average duration of 40.8 months follow‐up (range, 28 to 54 months). The average talo‐first metatarsal angle improved from 28.3° (range, 19° to 47°) preoperatively to 8.3° (range, 3° to 18°) and the calcaneo‐fifth metatarsal angle improved from 29.1° (range, 19° to 40°) preoperatively to 8.4° (range, 0° to 21°) at final follow‐up. The mean ratio of the medial‐to‐lateral column length improved from 1.14 ± 0.06 to 1.55 ± 0.09 with statistical significance (t = 3.566; P < 0.001).ConclusionsEight‐plate epiphysiodesis is an easy and effective method for the correction of residual forefoot adduction deformity after clubfoot treatment in growing children without the need of osteotomy.     

黄芪、前胡、白蒺藜对培养的肺动脉平滑肌细胞增殖及胶原分泌的影响

目的:寻找抑制肺动脉高压肺血管重建的药物。方法:体外培养的肺动脉平滑肌细胞(PASMC)加入中药制剂黄芪口服液、前胡口服液、白蒺藜口服液分别大、小两个剂量(大剂量10mg/ml,小剂量1mg/ml)干预,并掺入~3H-胸腺嘧啶脱氧核糖核苷(`3H-TdR),~3H-脯氨酸(~3H-Pro)检测每分钟液闪值(cpm),反映 PASMC 增殖及胶原合成分泌的改变。结果:~3H-TdR掺入值在加入黄芪、前胡、白蒺藜口服液后,无论大、小剂量,PASMC 均被抑制(P<0.001);对~3H-pro 的掺入值,在加入黄芪、前胡口服液后,大剂量、小剂量皆有阻抑作用(P<0.01和 P<0.05),白蒺藜只在大剂量时有作用(P<0.01)。结论:中药制剂黄芪、前胡、白蒺藜口服液可不同程度地阻抑 PASMC 的增殖和胶原合成过程,可能对肺动脉高压肺血管结构的重建起一定防治作用。

Major Depressive Disorder: Advances in Neuroscience Research and Translational Applications

Major depressive disorder (MDD), also referred to as depression, is one of the most common psychiatric disorders with a high economic burden. The etiology of depression is still not clear, but it is generally believed that MDD is a multifactorial disease caused by the interaction of social, psychological, and biological aspects. Therefore, there is no exact pathological theory that can independently explain its pathogenesis, involving genetics, neurobiology, and neuroimaging. At present, there are many treatment measures for patients with depression, including drug therapy, psychotherapy, and neuromodulation technology. In recent years, great progress has been made in the development of new antidepressants, some of which have been applied in the clinic. This article mainly reviews the research progress, pathogenesis, and treatment of MDD.

直肠腺癌新辅助放化疗疗效影响因素及病理完全缓解对预后的影响

  目的  探讨直肠腺癌新辅助放化疗（neoadjuvant chemoradiotherapy,NCRT）后病理完全缓解（pathologic complete response,pCR）的影响因素及pCR对生存的影响。  方法  回顾性分析2014年1月至2017年12月郑州大学附属肿瘤医院收治的98例直肠腺癌NCRT患者的临床病理资料,分析临床病理特征与pCR的关系以及pCR对预后的影响。  结果  98例患者NCRT后19例（19.4%）获得pCR。单因素分析显示,术前淋巴结转移情况、治疗前CEA水平、肿瘤大小、肿瘤侵犯肠壁周径程度以及KRAS基因状态与直肠腺癌NCRT后pCR相关。Logistic回归多因素分析显示,治疗前CEA≤5 μg/L（OR=4.095,95%CI:1.131~14.823,P=0.032）和肿瘤侵犯肠壁周径（≤1/2）（OR=3.268,95%CI:1.015~10.527,P=0.047）是影响直肠腺癌NCRT后pCR的独立因素。生存分析显示非pCR患者的3年无病生存率（disease-free survival,DFS）为71.1%,显著低于pCR患者100%（P < 0.05）;两者3年总生存率（overall survival,OS）分别为100%和88.5%,差异无统计学意义（P>0.05）。  结论  治疗前检测CEA以及评估肿瘤侵犯肠壁周径程度有助于预测直肠腺癌NCRT后pCR率,提示两者可作为新辅助放化疗疗效的评价指标,并指导临床进行个体化治疗。与pCR患者相比,非pCR直肠癌患者DFS较短。

Hydrolyzates of silkworm pupae (Bombyx mori) protein is a new source of angiotensin I-converting enzyme inhibitory peptides (ACEIP)

Silkworm pupae protein is a good source of high quality protein. The hydrolyzates of silkworm pupae protein catalyzed by neutrase, pepsin, acidic protease (Asperqiius usamii NO. 537), flavourzyme, alcalase, and trypsin with inhibitory activity on angiotensin I-converting enzyme (ACE) were identified by HPLC. The hydrolyzates catalyzed by acidic protease exerted the highest inhibitory activity on ACE. The hydrolyzing conditions were optimized by one-factor, factional factorial (FFD), and center composite (CCD) design methods, and response surface methodology (RSM). Statistical analyses showed that regression of the second-order model equation is suitable to describe ACE inhibitory bioactivity. The predicted inhibitory activity of hydrolyzates on ACE was 73.5 % at a concentration of 2.0 mg/ml. Optimized RSM technique decreased IC(50) of hydrolyzates inhibiting ACE to 1.4 mg/mL from 2.5 mg/ml. The molecular weight of the components of the hydrolyzates with inhibitory activity on ACE varied from less than 500 to about 1000 Da by ultra-filter analysis. These studies suggest that hydrolyzates of silkworm protein contain ACE inhibitory activity that could form a potential source of ACE inhibitor drugs.
