数字技术创新是新质生产力的组成部分,出口产品质量升级是高质量开放发展的基本要求。聚焦数字技术创新对出口产品质量的影响,从而探讨新质生产力促进高质量发展的渠道、机制和障碍,理论分析表明:数字技术创新降低资源投入、提升资源效率影响在位企业产品质量、临界企业产品质量和整体平均产品质量,对平均产品质量的影响具有不确定性。实证分析发现,数字技术创新自身难以提升平均产品质量,但与传统技术创新交叉项却显著稳健为正,这体现了数实融合、新旧融合的必要性;这一作用对中高技术产品并不显著,意味着中高技术产品质量升级可能更依靠技术创新质量;上述结论在考虑测量误差、样本选择、内生性等因素后依然显著。促进数字技术创新与传统技术创新融合是提升产品质量、促进高质量发展的关键,新质生产力无法孤立于旧生产力而发挥作用。

Surgical correction is central to current team-approached cleft treatment. Cleft surgeons are always concerned about the impact of their surgical maneuver on the growth of the maxilla. Hypoplastic maxilla, concaved mid-face and deformed dental arch have constantly been reported after cleft treatments. It is very hard to completely circumvent these postoperative complications by current surgical protocols. In this paper, we discussed the factors that inhibit the maxillofacial growth on cleft patients. These factors included pre-surgical intervention, the timing of cleft palate and alveolae repair, surgical design and treatment protocol. Also, we made a review about the influence on the maxillary growth in un-operated cleft patients. On the basis of previous researches, we can conclude that most of scholars express identity of views in these aspects： early palatoplasty lead to maxilla growth inhibition in all dimensions; secondary alveolar bone graft had no influence on maxilla sagittal growth; cleft lip repair inhibited maxilla sagittal length in patients with cleft lip and palate; Veau＇s pushback palatoplasty and Langenbeck＇s palatoplasty with relaxing incisions were most detrimental to growth; Furlow palatoplasty showed little detrimental effect on maxilla growth; timing of hard palate closure, instead of the sequence of hard or soft palate repair, determined the postoperative growth. Stilt, scholars hold controversial viewpoints in some issues, for example, un-operated clefts have normal growth potential or not, pre-surgical intervention and pharyngoplasty inhibited maxillofacial growth or not.

Chinese medicine（CM） has contributed to human health care for several thousand years and is still popular in Asian countries. But the mechanisms underlying CM remain obscure, and need to be clarified by modern biological subjects and methods. Recently, CM researches on epigenetics have gained obvious improvement following rapidly developed molecular technologies. In this review, we revealed mutual characteristics of epigenetics and CM, such as holism, yin-yang dynamic nature, reversibility and balance, and visceral manifestation. Moreover, epigenetic modifications, including DNA methylation, histone post-transcriptional modifications, micro RNA interference, etc. may help explore the molecular basis of CM syndrome classification, and mechanisms of Chinese herbal medicine（CHM）, CHM compounds and Chinese herbal formulae activities. Meanwhile, CM and epigenetics might promote each other and jointly develop following the continuous progress of epigenetics in CM researches.
