By consulting the ancient and moderm literature, this paper makes a textual research on the name, origin, quality evaluation, harvesting and processing of Olibanum, so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research, the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu(《名医别录》), until Ruxiang had been used as the correct name since Bencao Shiyi(《本草拾遗》) in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia, while the modern producing areas are Somalia, Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark, which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow, granular, translucent, no impurities such as sand and bark, sticky powder and aromatic smell. There were many processing methods in ancient times, including cleansing(water flying, removing impurities), grinding(wine grinding, rush grinding), frying(stir-frying, rush frying, wine frying), degreasing, vinegar processing, decoction. In modern times, the main processing methods are simplified to cleansing, stir-frying and vinegar processing. Nowadays, the commonly used specifications include raw, fried and vinegar-processed products. Among the three specifications, raw products is the Olibanum after cleansing, fried products is a kind of Olibanum processed by frying method, vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results, it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum, processing method should be carried out in accordance with the processing requirements of the formulas, otherwise used the raw products if the formulas without clear processing requirements.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous syestem (CNS) triggered by an autoimmune mechanism, which is the main cause of neurological disability in young people. In MS, a variety of glial cells participate in the pathogenesis and development of the disease, and oligodendrocytes (OL) and myelin cytes are destroyed by autoimmune mediated inflammation. Impaired OL production of oligodendrocyte progenitor cells (OPC) leads to persistent demyelination, myelin fragment accumulation and axonal injury, with clinical manifestation of CNS disability. Microglia (MG), which is involved in the inflammatory response and removal of myelin debris, plays a pivotal role in OPC differentiation and OL maturation, thereby directly or indirectly influencing the process of myelin regeneration. An interactive mechanism exists between these 2 components. The comprehension of the interrelationship between the 2 factors can provide enhanced insights into the pathogenesis of MS and facilitate the development of novel therapeutic strategies, thereby addressing pivotal scientific challenges encountered in clinical management of MS. Therefore, this review summarizes the dynamic changes of microglia in MS and its classic animal models, explores the internal relationship between MG and OL in this process, and focuses on the beneficial effects of targeted regulation of microglia, thereby promoting OPC differentiation and myelin regeneration, in order to provide a new research direction for MS treatment.

In order to provide the basis for the development of famous classical formulas, the name, origin, quality evaluation, harvesting and processing of Eucommiae Cortex were systematically researched by consulting the ancient herbal and medical books, combining with the modern literature. According to the textual research, materia medica in the past dynasties used Eucommiae Cortex as the correct name. Combined with characteristics, origin and efficacy, Eucommiae Cortex in ancient times to the present is the dry bark of Eucommia ulmoides from family Eucommiaceae. The earliest producing areas of Eucommiae Cortex are Henan, Shanxi, Shaanxi and Sichuan. Since the Ming dynasty, the producing areas have expanded to most of the regions in the country, and Sichuan, Shaanxi, Chongqing, Guizhou and Hubei are regarded as the authentic producing areas. It has been concluded that the quality of Eucommiae Cortex is best if the bark has thick body, large block, scraped rough skin, multi silk section and dark purple internal surface. In ancient times, the processing methods of Eucommiae Cortex were mainly included removing rough bark and cutting for raw use, processing with auxiliary materials such as honey, ginger juice, salt water, wine, and so on. While in modern times, the processing methods have become increasingly simplified which are mainly cutting raw materials after cleansing and salt processing. It is need to excavate the connotation of different processed products and restore the traditional main processing methods through standards. Based on the requirement of Eucommiae Cortex in Sanbitang, it is suggested to use ginger-processed products according to the research results, which is used ginger juice as auxiliary material and processed with stir frying method according to the 2020 edition of Chinese Pharmacopoeia.

Lung inflammation is an essential inducer of various diseases and is closely related to pulmonary-endothelium dysfunction. Herein, we propose a pulmonary endothelium-targeted codelivery system of anti-inflammatory indomethacin (IND) and antioxidant superoxide dismutase (SOD) by assembling the biopharmaceutical SOD onto the "vector" of rod-like pure IND crystals, followed by coating with anti-ICAM-1 antibody (Ab) for targeting endothelial cells. The codelivery system has a 237 nm diameter in length and extremely high drug loading of 39% IND and 2.3% SOD. Pharmacokinetics and biodistribution studies demonstrate the extended blood circulation and the strong pulmonary accumulation of the system after intravenous injection in the lipopolysaccharide (LPS)-induced inflammatory murine model. Particularly, the system allows a robust capacity to target pulmonary endothelium mostly due to the rod-shape and Ab coating effect. In vitro, the preparation shows the synergistic anti-inflammatory and antioxidant effects in LPS-activated endothelial cells. In vivo, the preparation exhibits superior pharmacodynamic efficacy revealed by significantly downregulating the inflammatory/oxidative stress markers, such as TNF-α, IL-6, COX-2, and reactive oxygen species (ROS), in the lungs. In conclusion, the codelivery system based on rod-like pure crystals could well target the pulmonary endothelium and effectively alleviate lung inflammation. The study offers a promising approach to combat pulmonary endothelium-associated diseases.

Objective:To evaluate regulatory effects of fibroblast growth factor receptor 3 (FGFR3) and human papillomavirus type 2 (HPV2) E2 protein on the differentiation of an immortalized human keratinocyte line HaCaT and a normal human epidermal keratinocyte line NHEK.Methods:In both HaCaT and NHEK cells, HPV2 E2-stably transfected cell lines (HPV2 E2-transfected groups) were established by using the lentivirus transfection method, wide-type FGFR3-overexpressing cells (FGFR3-WT transfected groups) and FGFR3-K650E mutant-overexpressing cells (FGFR3-K650E transfected groups) were constructed by using the plasmid transfection method, and cells transfected with blank vectors served as control groups (blank vector control groups). Real-time fluorescence-based quantitative PCR was performed to determine the mRNA expression of HPV2 E2, and Western blot analysis to determine the protein expression of HPV2 E2, FGFR3, and keratinocyte differentiation markers including loricrin, filaggrin, as well as involucrin. Laser scanning confocal microscopy was conducted to observe the spatial localization of HPV2 E2 and FGFR3 in HaCaT cells. Statistical analysis was carried out by using two-independent-sample t test for the comparison between two groups, one-way analysis of variance for the comparison among multiple groups, and Dunnett t-test for multiple comparisons. Results:The HPV2 E2-stably transfected cell lines were successfully constructed, and the expression of HPV2 E2 FLAG protein was significantly higher in the HPV2 E2-transfected groups than in the blank vector control groups in both HaCaT and NHEK cells ( t = 13.71, 25.91, respectively, both P < 0.001) ; both FGFR3-WT and FGFR3-K650E were successfully overexpressed in both HaCaT and NHEK cells, and the FGFR3 protein expression was significantly higher in the FGFR3-WT transfected groups and the FGFR3-K650E transfected groups than in the blank vector control groups ( F = 473.90, 579.90, respectively, both P < 0.001). In both HaCaT and NHEK cells, the expression of keratinocyte differentiation markers including loricrin, filaggrin, and involucrin was significantly upregulated in the HPV2 E2-transfected groups, the FGFR3-WT transfected groups, and the FGFR3-K650E transfected groups than in the blank vector control groups (all P < 0.05). In the HPV2 E2-stably transfected HaCaT and NHEK cells, the expression of loricrin, filaggrin, and involucrin was significantly down-regulated in the HPV2 E2 + FGFR3-WT transfected groups and the HPV2 E2 + FGFR3-K650E transfected groups than in the HPV2 E2 + blank vector groups (all P < 0.05). Laser scanning confocal microscopy showed the spatial co-localization of HPV2 E2 and FGFR3 in the nuclear membrane and cytoplasm of HaCaT cells. Conclusion:HPV2 E2 and FGFR3 could both induce the differentiation of HaCaT and NHEK cells, while FGFR3 could inhibit HPV2 E2-induced differentiation trend of HaCaT and NHEK cells, which may be related to the cellular spatial co-localization of HPV2 E2 and FGFR3.
