丹参酮提取物物理化学质量属性相关性分析

目的：探寻丹参酮提取物化学成分的含量与物理性质之间的相关性。方法：HPLC测定50批丹参酮提取物中隐丹参酮、丹参酮IIA的含量,经典方法测定物理性质,将成分含量与物理性质进行相关性分析。结果：两变量组组内的隐丹参酮与丹参酮IIA含量,D10、D50、D90 之间,松装密度与振实密度,豪斯纳比率与压缩度指数均具有较强的相关性,休止角与均齐度、豪斯纳比率、压缩度指数具有一定的相关性,但相关性不强。两变量组的原始变量组间相关性系数最大不超过0.400,相关性不强。经过典型相关分析,3对典型变量的相关性显著,相关系数分别为0.851,0.674,0.565。结论：对于丹参酮提取物的化学、物理质量属性,原始变量组内具有较好的相关性,但组间相关性较差。相比原始变量,典型变量呈现出了较好的组间相关性,表明丹参酮提取物的物理化学属性之间具有一定的相关性。

Silencing of Nesprin‐2 inhibits the differentiation of myofibroblasts from fibroblasts induced by mechanical stretch

Mechanical force plays a pivotal role in the pathogenesis of hypertrophic scar (HTS). Dermal fibroblasts and myofibroblasts are the key cells involved in HTS. Myofibroblasts in HTS possess different biochemical and biophysical characteristics by which myofibroblasts are often distinguished from fibroblasts. The role of mechanotransducers outside the nucleus in the pathogenesis of HTS has been reported in many studies. However, the role of Nesprin‐2 in HTS is not clear. Hence, we aim to construct a cell model of HTS and explore the role of Nesprin‐2 in this process. Myofibroblasts and fibroblasts were isolated from HTS and healthy skin tissues of the same patient. Fibroblasts were exposed to cyclic stretch with 10% magnitude and a frequency of 0.1 Hz for 3 days, 5 days, and 7 days, respectively. After the cell model was confirmed, fibroblasts transfected with siRNA targeting human Nesprin‐2 were exposed to cyclic stretch. The mechanical behaviour and biochemical reaction of the dermal fibroblasts were analysed. The stretched fibroblasts at day 5 showed the same mechanotransductive and biochemical features as unstretched myofibroblasts. Mechanical strain could induce the myofibroblasts differentiation and a cell model of HTS was established successfully at day 5. The expressions of lamin A/C, alpha‐smooth muscle actin, transforming growth factor beta 1, and collagen type I in fibroblasts were reduced by the silencing of Nesprin‐2. Mechanical strain could induce the myofibroblasts differentiation and silencing of Nesprin‐2 could block the mechanical stimulation of terminal myofibroblasts differentiation. Nesprin‐2 might be a potential target to treat the HTS.

Anti-tumor pharmacology of natural products targeting mitosis

Cancer has been an insurmountable problem in the history of medical science. The uncontrollable proliferation of cancer cells is one of cancer’s main characteristics, which is closely associated with abnormal mitosis. Targeting mitosis is an effective method for cancer treatment. This review summarizes several natural products with anti-tumor effects related to mitosis, focusing on targeting microtubulin, inducing DNA damage, and modulating mitosis-associated kinases. Furthermore, the main disadvantages of several typical compounds, including drug resistance, toxicity to non-tumor tissues, and poor aqueous solubility and pharmacokinetic properties, are also discussed, together with strategies to address them. Improved understanding of cancer cell mitosis and natural products may pave the way to drug development for the treatment of cancer.     

Risk factors of wound infection after lung transplantation: a narrative review

Background and ObjectiveThe incidence of incision infection after lung transplantation is prominently high which affect the prognosis. Summarizing the risk factors related to incision infection after lung transplantation contribute to the control of incision infection by pre-controlling the risk factors. The objective is to summarize risk factors related to wound infection after lung transplantation.MethodsPubMed was used to research the literature relating to the risk factors to incision infection after lung transplantation through 1990 to 2022. The retrieval strategy were Medical Subject Heading (MeSH) terms combined entry terms. Two researchers conducted the literature retrieval independently. Two researchers independently evaluate the quality of the literature and summarize the indicators.Key Content and FindingsA total of 98 researches were collected from PubMed and 8 articles described the related risk factors of incision infection after lung transplantation. All of the 8 articles were retrospective studies, of which 4 articles were grouped by the delayed chest closure (DCC) execution and the other 4 articles were grouped by the surgical site infection (SSI) occurred. Two articles performed multivariate regression analysis to determine the independent risk factors of SSI after lung transplantation and the other 6 articles compared the SSI rate in different patients population. The integrated results showed that bronchoalveolar lavages (BALs), smoking status, body mass index (BMI), diabetes, operation duration, thoracic drainage tube placement time and DCC were related to the SSI after lung transplantation.ConclusionsBALs, smoking status, BMI, diabetes, operation duration, thoracic drainage tube placement time and DCC were related to the SSI after lung transplantation.
