Research progress in the intervention of Chinese herb monomers on diabetic retinal neurodegeneration / 国际眼科杂志(Guoji Yanke Zazhi)

Diabetic retinopathy(DR)has been traditionally considered a purely microvascular disease in the retina. Currently, mainstream therapies focus only on advanced vascular complications and a single molecular target-vascular endothelial growth factor(VEGF). However, the research is shifting towards a more comprehensive view that DR is a neurovascular disease caused by neurovascular unit(NVU)injury. In the early stage of DR, diabetic retinal neurodegeneration(DRN)dominates and may precede the retinal microvascular abnormalities. Moreover, neuronal apoptosis can further lead to microvascular injury and blood-retinal barrier(BRB)disruption. Therefore, it makes sense to develop new therapeutic strategies to prevent or reverse DRN. However, no drug targeting DRN has been approved for clinical use. In recent years, it has become a trend to study the protective effect of traditional Chinese medicine on the retina. The primary research focuses on Chinese herb monomers. This article reviews the research status of representative monomers in DRN to provide references for the early treatment of DR and development of new drugs.

Research progress on anti-inflammatory effects of plant-derived cannabinoid type 2 receptor modulators / 中国中药杂志

Excessive and persistent inflammatory responses are a potential pathological condition that can lead to diseases of various systems, including nervous, respiratory, digestive, circulatory, and endocrine systems. Cannabinoid type 2 receptor(CB2R) belongs to the G protein-coupled receptor family and is widely distributed in immune cells, peripheral tissues, and the central nervous system. It plays a role in inflammatory responses under various pathological conditions. The down-regulation of CB2R activity is an important marker of inflammation and and CB2R modulators have been shown to have anti-inflammatory effects. This study explored the relationship between CB2R and inflammatory responses, delved into its regulatory mechanisms in inflammatory diseases, and summarized the research progress on CB2R modulators from plants other than cannabis, including plant extracts and monomeric compounds, in exerting anti-inflammatory effects. The aim is to provide new insights into the prevention and treatment of inflammatory diseases.

Electroacupuncture Attenuated Phenotype Transformation of Vascular Smooth Muscle Cells via PI3K/Akt and MAPK Signaling Pathways in Spontaneous Hypertensive Rats / 中国结合医学杂志

OBJECTIVE@#To investigate whether the antihypertensive mechanism of electroacupuncture (EA) is associated with attenuating phenotype transformation of vascular smooth muscle cells (VSMCs) via phosphoinositide3-kinase (PI3K)/protein kinase B (Akt) and mitogen-activated protein kinase (MAPK) signaling pathways.@*METHODS@#Eight Wistar-ktoyo (WKY) rats were set as normal blood pressure group (normal group). A total of 32 spontaneous hypertensive rats (SHRs) were randomly divided into 4 groups using random number tables: a model group, an EA group, an EA+PI3K antagonist group (EA+P group), and an EA+p38 MAPK agonist+extracellular signal-regulated kinase (ERK) agonist group (EA+M group) (n=8/group). SHRs in EA group, EA+P group and EA+M group received EA treatment 5 sessions per week for continuous 4 weeks, while rats in the normal and model groups were bundled in same condition. The systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) of each rat was measured at 0 week and the 4th week. After 4-week intervention, thoracic aorta was collected for hematoxylin-eosin (HE) staining, immunohistochemistry [the contractile markers α-smooth muscle actin (α-SMA) and calponin and the synthetic marker osteopontin (OPN)] and Western blot [α-SMA, calponin, OPN, PI3K, phosphorylated-Akt (p-Akt), Akt, p-p42/44 ERK, total p42/44 ERK, p-p38 MAPK and total p38 MAPK].@*RESULTS@#EA significantly reduced SBP, DBP and MAP (P<0.01). HE staining showed that the wall thickness of thoracic aorta in EA group was significantly decreased (P<0.01). From results of immunohistochemistry and Western blot, EA increased the expression of α-SMA and calponin, and decreased the expression of OPN (P<0.01). In addition, the expression of PI3K and p-Akt increased (P<0.01), while the expression of p-p42/44 ERK and p-p38 MAPK decreased in EA group (P<0.01). However, these effects were reversed by PI3K antagonist, p38 MAPK agonist and ERK agonist.@*CONCLUSIONS@#EA was an effective treatment for BP management. The antihypertensive effect of EA may be related with inhibition of phenotypic transformation of VSMCs, in which the activation of PI3K/Akt and the repression of MAPK pathway were involved.

Genetic diversity and genetic structures of original plants of Viticis Fructus:an SSR markers-based analysis / 中国中药杂志

The present study aimed to provide the protection strategies for wild germplasm resources of original plants of Viticis Fructus and a theoretical basis for the sustainable use of Viticis Fructus. The genetic diversity and genetic structures of the 232 indivi-duals in 19 populations of Vitex rotundifolia and V. trifolia were analyzed by eight SSR markers with tools such as Popgene32, GenAlex 6.502, and STRUCTURE. Bottleneck effect was detected for the population with more than 10 individuals. The results indicated that 42 and 26 alleles were detected from the populations of V. rotundifolia and V. trifolia, respectively, with average expected heterozygo-sities of 0.448 6 and 0.583 9, which are indicative of low genetic diversity. AMOVA revealed the obvious genetic variation of V. rotundifolia and V. trifolia within population(84.43%, P<0.01; 60.37%, P<0.01). Furthermore, in eight SSR loci, six from V. rotundifolia populations and two from V. trifolia populations failed to meet Hardy-Weinberg equilibrium expectations(P<0.05), which confirmed that the populations experienced bottleneck effect. As assessed by Mantel test, geographical distance posed slight impacts on the genetic variation between the populations of V. rotundifolia and V. trifolia. Principal component analysis(PCA) and STRUCTURE analysis demonstrated evident introgression of genes among various populations. The original plants of Viticis Fructus were confirmed low in genetic diversity and genetic differentiation level. Therefore, the protection of wild resources of original plants of Viticis Fructus should be strengthened to ensure its sustainable use.

Research progress on protective effect of traditional Chinese medicine and natural medicine on methotrexate-induced liver toxicity / 中国中药杂志

Methotrexate(MTX) is a commonly used antimetabolite, which can be used in the treatment of a variety of diseases. However, hepatotoxicity in the use of MTX severely limits its clinical use. Therefore, how to prevent and treat hepatotoxicity of MTX has become an urgent clinical problem. This paper summarizes and analyzes relevant literatures on the prevention and treatment of hepa-totoxicity caused by MTX with traditional Chinese medicines and natural medicines in recent years. MTX-induced hepatotoxicity mechanisms include folate pathway, oxidative stress damage and adenosine pathway, of which oxidative stress theory is the main research direction. A total of 14 kinds of traditional Chinese medicine and natural medicine extracts including white peony root, and 21 kinds of natural monomer compounds, including berberine, play an anti-MTX-induced hepatotoxic effect by resisting oxidative stress, inhibiting inflammation and regulating signal pathways. According to current studies on the prevention and treatment of hepatotoxicity induced by MTX with traditional Chinese medicines and natural medicines, there are insufficiencies, such as partial and superficial mechanism studies, inadequate combination of experimental research and clinical practice, non-standard experimental design and lack of application of advanced technologies and methods. This paper systematically reviewed the effects and mechanisms of traditional Chinese medicines and natural medicines against hepatotoxicity induced by MTX and defined current studies and deficiencies, in the expectation of proposing new study strategies and directions and providing scientific basis for rational clinical use of MTX and development of new drugs against MTX hepatotoxicity.

Research progress on natural cannabinoid receptor type 2( CB2R)regulators and their effects on bone metabolism / 中国中药杂志

Cannabinoid receptor type 2( CB2 R),a member of the G protein-coupled receptor( GPCR) superfamily,has a variety of biological activities,such as regulating pain response,resisting inflammation and fibrosis,and mediating bone metabolism. Some CB2 R regulators exhibit a good regulatory effect on bone metabolism. Cannabinoids in Cannabis sativa can cause psychoactive effects despite various pharmacological actions they exerted by targeting CB2 R. Therefore,it is of great significance to discover CB2 R regulators in non-Cannabis plants for finding new lead compounds without psychoactive effects and elucidating the action mechanism of plant drugs. The present study clarifies the discovery,structure,and physiological functions of CB2 R,especially its regulatory effects on bone metabolism,summarized CB2 R regulators extracted from non-Cannabis plants,and systematically analyzes the regulatory effects of CB2 R regulators on bone metabolism in animals,osteoblasts,and osteoclasts,to provide a scientific basis for the discovery of new CB2 R regulators and the development of anti-osteoporotic drugs.

Humulus lupulus L. Extract Prevents Ovariectomy-Induced Osteoporosis in Mice and Regulates Activities of Osteoblasts and Osteoclasts / 中国结合医学杂志

OBJECTIVE@#To systematically evaluate the protective effects of Humulus lupulus L. extract (HLE) on osteoporosis mice.@*METHODS@#In vivo experiment, a total of 35 12-week-old female ICR mice were equally divided into 5 groups: the sham control group (sham); the ovariectomy with vehicle group (OVX); the OVX with estradiol valerate [EV, 0.2 mg/(kg•d)] the OVX with low- or high-dose HLE groups [HLE, 1 g/(kg•d) and 3 g/(kg•d)], 7 in each group. Treatment began 1 week after the ovariectomized surgery and lasted for 12 weeks. Bone mass and trabecular bone mircoarchitecture were evaluated by micro computed tomography, and bone turnover markers in serum were evaluated using enzyme-linked immunosorbent assay (ELISA) kits. In vitro experiment, osteoblasts and osteoclasts were treated with HLE at doses of 0, 4, 20 and 100 µg/mL. Biomarkers for bone formation in osteoblasts and bone resorption in osteoclasts were analyzed.@*RESULTS@#Compared with the OVX group, HLE exerted bone protective effects by the increase of estradiol (P<0.05), the improvement of cancellous bone structure, bone mineral density (P<0.01) and the reduction of serum alkaline phosphatase (ALP), tartrate resistant acid phosphatase (TRAP), bone gla-protein, c-terminal telopeptides of type I collagen (CTX-I) and deoxypyridinoline levels (P<0.01 for all). In vitro experiment, compared with the control group, HLE at 20 µg/mL promoted the cell proliferation (P<0.01), and increased the expression of bone morphogenetic protein-2 and osteopontin levels in osteoblasts (both P<0.05). HLE at 100 µg/mL increased the osteoblastic ALP activities, and HLE at all dose enhanced the extracellular matrix mineralization (both P<0.01). Furthermore, compared with the control group, HLE at 20 µg/mL and 100 µg/mL inhibited osteoclastic TRAP activity (P<0.01), and reduced the expression of matrix metalloproteinase-9 and cathepsin K (both P<0.05).@*CONCLUSION@#HLE may protect against bone loss, and have potentials in the treatment of osteoporosis.

Evaluation of unilateral and bilateral bimodal bone conduction hearing intervention in patients with bilateral microtia-atresia / 中华耳鼻咽喉头颈外科杂志

Objectives: To evaluate the therapeutic effects of unilateral/bilateral bone conduction hearing rehabilitation in patients with bilateral microtia accompanied with severe conductive hearing loss following staged auricle reconstruction and bonebridge implantation. Methods: Thirty-two patients, including 20 males and 12 females, with an average age of 11.8, who received surgical treatment in Peking Union Medical College Hospital (PUMCH) from March, 2016 to January, 2020 with bilateral microtia-atresia were included. Hearing thresholds, speech perception and high-resolution CT of the temporal bone were evaluated prior to surgery and individualized surgery plans (staged auricle reconstruction and bonebridge implantation) were made. Hearing thresholds and speech perception in quiet and noise (SNR = 5 dB) using unilateral Bonebridge were tested two weeks after the implantation surgery when the Bonebridge was activated and at 3th, 6th, 12th month after activation. Hearing thresholds and speech perception were also tested at least three months after the activation of the Bonebridge under three conditions: unaided, unilateral Bonebridge, and bilateral bone conduction hearing devices (Bonebridge plus contralateral ADHEAR). The international hearing aid assessment questionnaire (IOI-HA) and Glasgow children's benefit questionnaire were used to evaluate the subjective benefits of the patients. SPSS 21.0 software was used for statistical analysis. Results: Among these 32 patients, nine were conducted Bonebridge implantation surgery before auricle reconstruction, six were simultaneously with auricle reconstruction and 17 were implanted after auricle reconstruction surgery. Compared with unaided, the mean hearing thresholds (0.5, 1, 2, and 4 kHz) and speech perception following unilateral BCHD and bilateral BCHD attachment were improved significantly (P<0.05 each). The speech perceptin in noise of bilateral BCHD was better than unilateral (P<0.05 each). The modified questionnaire revealed high levels of patient satisfaction following use of both unilateral and bilateral devices. Conclusions: Individulized surgical procedures involving auricle reconstruction and Bonebridge implantation are safe and effective for patients with bilateral microtia-atresia, solving both appearance and hearing problems. Speech perception in noise is better following bilateral BCHD than unilateral BCHD attachment.
