RESUMEN
Familial Hypercholesterolemia (FH), an autosomal dominant genetic disease, is increasingly emerging as a global threat. To learn more about the development of FH, 1 617 papers about FH and related research were retrieved in the Web of Science Core Collection from 2011 to 2021. Then, these publications were scientometrically analyzed based on CiteSpace and VOSviewer in terms of spatiotemporal distribution, author distribution, subject categories, topic distribution, and references. The results showed that research on FH is at a stable stage. More FH research has been conducted in developed countries, implying the necessity for strengthening international cooperation and exchanges. We have obtained scholars, institutions, relevant journals, and representative literatures that play an important role in FH. The research direction of FH is on the mechanisms of FH and its complications, diagnosis, statin therapy, and new lipid-lowering drug therapy. Care is the research frontier in FH, and it is in an explosive period.

ETHNOPHARMACOLOGICAL RELEVANCE: Zukamu Granules (ZKMG) is one of the representative Uygur patent drugs widely used in China, which is included in the National Essential Drugs List (2018 edition). As the first choice for common cold treatment in Uygur medicine theory, it has unique anti-inflammatory and antitussive efficacy. AIM OF THE STUDY: According to the recent inflammatory hypothesis, the abnormal proliferation, autophagy and apoptosis process of lung cells especially alveolar macrophages (AMs) may play an important role in the progress of idiopathic pulmonary fibrosis (IPF). Therefore, we came up with a novel treatment approach for IPF by regulating the balance of AMs "autophagy - apoptosis", and took ZKMG as the sample drug for our research. MATERIALS AND METHODS: Network pharmacology approach was conducted to predict the active components and intersected targets between ZKMG and inflammation. PPI network, GO and KEGG enrichment analysis were screened and analyzed to predict the anti-inflammatory mechanism of ZKMG. Biological experiment adopted from 128 rats, and hematoxylin-eosin staining, flow cytometry and RT-PCR were performed to examine the pathological morphology, HYP contents in lung tissue, AMs counting, AMs apoptosis, AMs phagocytosis rate, mRNA relative quantity determination of 3 key factors associated with AMs "autophagy - apoptosis" and mRNA relative quantity determination of AMs surface receptor signaling pathway. RESULTS: The predicted results showed that the mechanism of ZKMG in anti-inflammatory was related to the response and elimination of inflammatory stimuli, the intervention of apoptosis and surface receptor signaling pathways of cells. The verification experiments showed that excessive apoptosis and insufficient autophagy of AMs always existed in the progression of IPF. ZKMG could inhibit AMs proliferation, significantly reduce AMs apoptosis rate, intervene the binding of the Bcl-2 to Beclin 1, inhibit the Caspase 3 activation, stimulate the enhancement of AMs phagocytosis, and inhibit the high expression of TLR4/MyD88/NF-κB surface receptor signaling pathway, which may partly retard the fibrosis process. CONCLUSION: By inhibiting proliferation, enhancing phagocytosis, inhibiting the formation of Bcl-2 complex, and inhibiting the high expression of MYD88-dependent TLR4 signaling pathway, ZKMG can regulate the balance of AMs "autophagy - apoptosis" in the alveolitis stage to retard the fibrosis process partly. With a comprehensive strategy of "target prediction - experimental verification", we have demonstrated that inhibiting the apoptosis and promoting autophagy activity of AMs may suggest a new perspective for IPF treatment, which would provide reference for the subsequent development.

Background: Homozygous familial hypercholesterolaemia (HoFH) patients have little or no low-density lipoprotein receptor (LDLR) function. HMG-CoA (3-hydroxy-3-methyl glutaryl coenzyme A) reductase inhibitors (statins) and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have limited lipid-lowering effects, therefore, there is an urgent need to develop new HoFH treatments. In 2012, the US Food and Drug Administration (FDA) approved the administration of lomitapide for lowering low-density lipoprotein cholesterol (LDL-C) levels. However, lomitapide is associated with various gastrointestinal disorders, elevated hepatic alanine aminotransferase (ALT) levels and other adverse reactions, thus, its long-term efficacy and safety in pediatrics and adults should be evaluated. A systematic review conducted in 2017 reported the efficacy and safety of lomitapide in Family hypercholesterolaemia (FH) patients. In this systematic review, we elucidate on the efficacy and safety of lomitapide in HoFH patients. Methods: A search was conducted in PubMed, Embase, Web of Science and Cochrane library databases to identify valid studies involving lomitapide-treated HoFH patients published before 11th August 2021. Results: A total of 18 clinical studies involving 120 lomitapide-treated HoFH patients were identified. Lomitapide significantly suppressed LDL-C levels in HoFH patients. Clinical manifestations for lomitapide in children were comparable to those in adults. The most common adverse events were gastrointestinal disturbances and elevated ALT levels. However, most patients tolerated the treatment-associated adverse reactions. Low-fat diets and drug dose adjustments were appropriate measures for controlling the treatment-associated adverse reactions. Conclusions: In pediatric and adult HoFH patients, lomitapide significantly suppresses LDL-C levels, therefore, it is an important option for HoFH treatment. The most common adverse events of lomitapide treatment include gastrointestinal disorders and elevated hepatic ALT levels. Despite the limitations, lomitapide is feasible for long-term treatment of HoFH patients, with dietary and safety monitoring. Registration Number in PROSPERO: CRD42021284425.

OBJECTIVE: To investigate the therapeutic effect of combined application of Wuweizi (Schisandrae Chinensis Fructus) and dexamethasone in rats with idiopathic pulmonary fibrosis (IPF) and the possible protective effect of Wuweizi against dexamethasone-induced glucocorticoid osteoporosis (GIOP). METHODS: There were five groups in this study, including the sham operation group, model group, Wuweizi group, dexamethasone group, and the combination group. A rat IPF model was made by the endotracheal injection of bleomycin. After modeling, rats were given drug interventions for 7 and 28 days. Rats were sacrificed for pathological morphology examination of the bone and lung and quantitative determination of biochemical markers of bone metabolism and angiogenesis-related cytokine to observe therapeutic efficacy on the 7th and 28th day. ELISA was used for the quantitative determination of tartrate-resistant acid phosphatase (TRACP), bone alkaline phosphatase (BALP), hypoxia-inducible factor (HIF-1α), platelet-derived growth factor (PDGF), pigment epithelium-derived factor (PEDF), and endostatin in serum. The concentrations of calcium (Ca) and phosphorus (P) were detected with the automatic biochemical analyzer. RESULTS: After drug interventions for 7 and 28 days, alveolitis and pulmonary fibrosis in treatment groups showed significant improvement compared with those in the model group (P < 0.05). Bone histopathological figures showed severely damaged trabecular bone and bone marrow cavity in the dexamethasone group, but it was significantly alleviated in the combination group. The concentrations of BALP and Ca in the combination group were significantly higher than those in the dexamethasone group after treatment, while the concentrations of TRACP and P were lower than those in the dexamethasone group (P < 0.05). Bone histopathological figures showed severely damaged trabecular bone and bone marrow cavity in the dexamethasone group, but it was significantly alleviated in the combination group. The concentrations of BALP and Ca in the combination group were significantly higher than those in the dexamethasone group after treatment, while the concentrations of TRACP and P were lower than those in the dexamethasone group (α), platelet-derived growth factor (PDGF), pigment epithelium-derived factor (PEDF), and endostatin in serum. The concentrations of calcium (Ca) and phosphorus (P) were detected with the automatic biochemical analyzer. P < 0.05). Bone histopathological figures showed severely damaged trabecular bone and bone marrow cavity in the dexamethasone group, but it was significantly alleviated in the combination group.

Objective: This research aims to analyze the application regularity of Chinese patent medicine during the COVID-19 epidemic by collecting the names of the top three Chinese patent medicines used by 24 hospitals in 14 provinces of China in four time periods (January 20-22, February 16-18, March 01-03, April 01-03, 2020), and explore its contribution to combating the disease. Methods: 1) We built a database of the top three Chinese patent medicines used by 24 hospitals. 2) The frequency and efficacy distribution of Chinese patent medicine were analyzed with risk areas, regions, and hospitals of different properties as three factors. 3) Finally, we analyzed the differences in the use of heat-clearing and non-heat-clearing medicines among the three factors (χ2 test) and the correlation between the Chinese patent medicine and COVID-19 epidemic (correlation analysis) with SPSS 23.0 statistical software. Results: 1) The heat-clearing medicine was the main use category nationwide during January 20-22, 2020. Meanwhile, there was a significant difference in the utilization rate of heat-clearing and non-heat-clearing medicine in different risk areas (p < 0.01). 2) The variety of Chinese patent medicine was increased nationwide during February 16-18, 2020, mainly including tonics, blood-activating and resolving-stasis, and heat-clearing medicines. Meanwhile, there was a significant difference in the utilization rate of heat-clearing and non-heat-clearing medicine in the southern and northern regions (p < 0.05). 3) Tonics, and blood-activating and resolving-stasis medicines became the primary use categories nationwide during March 01-03, 2020. 4) The tonics class, and blood-activating and resolving-stasis medicine were still the primary categories nationwide during April 01-03, 2020. Meanwhile, there was a significant difference in the utilization rate of heat-clearing and non-heat-clearing medicine in different risk areas (p < 0.01). Conclusion: Chinese patent medicine has a certain degree of participation in fighting against the COVID-19. The efficacy distribution is related to the risk area, region, and hospital of different properties, among which the risk area is the main influencing factor. It is hoped that future research can further collect the application amount of Chinese patent medicine used in hospitals all over the country, so as to perfectly reflect the relationship between Chinese patent medicine and the epidemic situation.
RESUMEN
Pulmonary fibrosis is a chronic and progressive interstitial lung disease of known and unknown etiology. Over the past decades, macrophages have been recognized to play a significant role in IPF pathogenesis. According to their anatomical loci, macrophages can be divided to alveolar macrophages (AMs) subtypes and interstitial macrophages subtypes (IMs) with different responsibility in the damage defense response. Depending on diverse chemokines and cytokines in local microenvironments, macrophages can be induced and polarized to either classically activated (M1) or alternatively activated (M2) phenotypes in different stages of immunity. Therefore, we hypothesize that there is a "phagocytosis-secretion-immunization" network regulation of pulmonary macrophages related to a number of chemokines and cytokines. In this paper, we summarize and discuss the role of chemokines and cytokines involved in the "phagocytosis-secretion-immunization" network regulation mechanism of pulmonary macrophages, pointing toward novel therapeutic approaches based on the network target regulation in the field. Therapeutic strategies focused on modifying the chemokines, cytokines and the network are promising for the pharmacotherapy of IPF. Some Traditional Chinese medicines may have more superiorities in delaying the progression of pulmonary fibrosis for their multi-target activities of this network regulation.

Macrophages are a group of immune cells with pluripotency and plasticity that can differentiate into different phenotypes under different microenvironments in vitro and in vivo. In the development of pulmonary fibrosis, there are alveolar macrophages and interstitial macrophages, which are polarized to different cell phenotypes at different stages of development. And their polarized phenotypes include M1 macrophages and M2 macrophages. In the inflammation early stages of pulmonary fibrosis, the increase of classical activated macrophages are helpful to clear pathogenic microorganisms and promote the progress of inflammation. In the fibrosis stage, the alternatively activated macrophages increased, which inhibiting the inflammatory reaction or directly promoting tissue fibrosis, on the other hand, it also promoting the fibrosis degradation. To clarify the polarization and polarization mechanisms of macrophages in pulmonary fibrosis will be conducive to the treatment of pulmonary fibrosis. In IPF, the polarization mechanism of M1 and M2 is closely related to TGF-ß1/Smad. TGF-ß1/Smad pathway plays an important regulatory role in liver fibrosis, renal fibrosis, myocardial fibrosis, scars, tumors and other diseases. Blocking the signaling of TGF-ß1 by Smad3 and Smad4 is beneficial to inhibit the polarization of AM, which in turn helps to inhibit the progression of IPF.

OBJECTIVE: To observe the effects of serum containing Mahuang (Herba Ephedra Sinica) or Wuweizi (Fructus Schisandrae Chinensis) on the migration of alveolar macrophages (AM) and interstitial macrophages (IM) from normal rats, and to analyze and compare the mechanisms leading to cell migration differences. METHODS: Rats were randomly divided into three groups: Mahuang (Herba Ephedra Sinica), Wuweizi (Fructus Schisandrae Chinensis), and blank serum. After treatment with the herbs, serum was extracted from the rats. AM and IM were isolated from normal rats and cultured. The effects of Mahuang (Herba Ephedra Sinica) and Wuweizi (Fructus Schisandrae Chinensis) medicated serum on normal rat AM and IM chemotactic migration were determined by transwell assays. The CC chemokine receptor (CCR) 2, CCR5, voltage-gated Kvl. 3 K+ channel (Kv1. 3), and voltage-gated Kvl. 5 K+ channel (Kv1. 5) protein levels were analyzed by western blotting. RESULTS: The migration quantities of AM and IM in the Mahuang (Herba Ephedra Sinica) and Wuweizi (Fructus Schisandrae Chinensis) medicated serum groups were significantly higher than those in the blank serum group (P < 0.01). Compared with the Wuweizi (Fructus Schisandrae Chinensis) medicated serum group, the migration quantity of cultured rat AM in the Mahuang (Herba Ephedra Sinica) medicated serum group was significantly increased (P < 0.01). Meanwhile, compared with the Mahuang (Herba Ephedra Sinica) medicated serum group, the migration quantity of cultured rat IM in the Wuweizi (Fructus Schisandrae Chinensis) medicated serum group was significantly increased (P < 0.01). CCR2, CCR5, Kv1. 3, and Kv1. 5 proteins were expressed on the AM cell surface, and showed significantly higher expression in the Mahuang (Herba Ephedra Sinica) medicated serum group compared with the Wuweizi (Fructus Schisandrae Chinensis) medicated serum group. In contrast, CCR5, Kv1.3, and Kv1.5 proteins were expressed on the IM cell surface, and showed significantly higher expression in the Wuweizi (Fructus Schisandrae Chinensis) medicated serum group compared with the Mahuang (Herba Ephedra Sinica) medicated serum group. CONCLUSION: Mahuang (Herba Ephedra Sinica) and Wuweizi (Fructus Schisandrae Chinensis) can promote AM and IM migration ability, with Mahuang (Herba Ephedra Sinica) targeting AM more apparently and Wuweizi (Fructus Schisandrae Chinensis) targeting IM more apparently. The mechanism may be that, by stimulating cells, Mahuang (Herba Ephedra Sinica) and Wuweizi (Fructus Schisandrae Chinensis) promote expression of CCR2 and CCR5 receptors on the AM and IM cell surface, which pass signals to Kvl.3 and Kvl.5 ion channels, leading to changes in the cytoskeleton, and ultimately promoting chemotactic cell migration.
