Objective: To discuss the influence of Sailuotong (, SLT) on the Neurovascular Unit (NVUs) of amyloid precursor protein (APP)/presenilin-1(PS1) mice and evaluate the role of gas supplementation in activating blood circulation during the progression of Alzheimer's disease (AD).
Methods: The mice were allocated into the following nine groups: (a) the C57 Black (C57BL) sham-operated group (control group), (b) ischaemic treatment in C57BL mice (the C57 ischaemic group), (c) the APP/PS1 sham surgery group (APP/PS1 model group), (d) ischaemic treatment in APP/PS1 mice (APP/PS1 ischaemic group), (e) C57BL mice treated with aspirin following ischaemic treatment (C57BL ischaemic + aspirin group), (f) C57BL mice treated with SLT following ischaemic treatment (C57BL ischaemic + SLT group), (g) APP/PS1 mice treated with SLT (APP/PS1 + SLT group), (h) APP/PS1 mice treated with donepezil hydrochloride following ischaemic treatment (APP/PS1 ischaemic + donepezil hydrochloride group) and (i) APP/PS1 mice treated with SLT following ischaemic treatment (APP/PS1 ischaemic + SLT group). The ischaemic model was established by operating on the bilateral common carotid arteries and creating a microembolism. The Morris water maze and step-down tests were used to detect the spatial behaviour and memory ability of mice. The hippocampus of each mouse was observed by haematoxylin and eosin (HE) and Congo red staining. The ultrastructure of NVUs in each group was observed by electron microscopy, and various biochemical indicators were detected by enzyme-linked immunosorbent assay (ELISA). The protein expression level was detected by Western blot. The mRNA expression was detected by quantitative real-time polymerase chain reaction (qRT-PCR).
Results: The results of the Morris water maze and step-down tests showed that ischemia reduced learning and memory in the mice, which were restored by SLT. The results of HE staining showed that SLT restored the pathological changes of the NVUs. The Congo red staining results revealed that SLT also improved the scattered orange-red sediments in the upper cortex and hippocampus of the APP/PS1 and APP/PS1 ischaemic mice. Furthermore, SLT significantly reduced the content of Aβ, improved the vascular endothelium and repaired the mitochondrial structures. The ELISA detection, western blot detection and qRT-PCR showed that SLT significantly increased the vascular endothelial growth factor (VEGF), angiopoietin and basic fibroblast growth factor, as well as the levels of gene and protein expression of low-density lipoprotein receptor-related protein-1 (LRP-1) and VEGF in brain tissue.
Conclusions: By increasing the expression of VEGF, SLT can promote vascular proliferation, up-regulate the expression of LRP-1, promote the clearance of Aβ and improve the cognitive impairment of APP/PS1 mice. These results confirm that SLT can improve AD by promoting vascular

Objective: To investigate the impact of Yemazhui (Herba Eupatorii Lindleyani, HEL) against lipopolysaccharide (LPS)-induced acute lung injury (ALI) and explore its underlying mechanism in vivo.
Methods: The chemical constituents of HEL were analyzed by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry method. Then, HEL was found to suppress LPS-induced ALI in vivo. Six-week-old male Sprague-Dawley rats were randomly divided into 6 groups: control, LPS, Dexamethasone (Dex), HEL low dose 6 g/kg (HEL-L), HEL medium dose 18 g/kg (HEL-M) and HEL high dose 54 g/kg (HEL-H) groups. The model rats were intratracheally injected with 3 mg/kg LPS to establish an ALI model. Leukocyte counts, lung wet/dry weight ratio, as well as myeloperoxidase (MPO) activity were determined followed by the detection with hematoxylin and eosin staining, enzyme linked immunosorbent assay, quantitative real time polymerase chain reaction, western blotting, immunohistochemistry, and immunofluorescence. Besides, to explore the effect of HEL on ALI-mediated intestinal flora, we performed 16s rRNA sequencing analysis of intestinal contents.
Results: HEL attenuated LPS-induced inflammation in lung tissue and intestinal flora disturbance. Mechanism study indicated that HEL suppressed the lung coefficient and wet/dry weight ratio of LPS-induced ALI in rats, inhibited leukocytes exudation and MPO activity, and improved the pathological injury of lung tissue. In addition, HEL reduced the expression of tumor necrosis factor-alpha, interleukin-1beta (IL-1β) and interleukin-6 (IL-6) in bronchoalveolar lavage fluid and serum, and inhibited nuclear displacement of nuclear factor kappa-B p65 (NF-κBp65). And 18 g/kg HEL also reduced the expression levels of toll-like receptor 4 (TLR4), myeloid differentiation factor 88, NF-κBp65, phosphorylated inhibitor kappa B alpha (phospho-IκBα), nod-like receptor family pyrin domain-containing 3 protein (NLRP3), IL-1β, and interleukin-18 (IL-18) in lung tissue, and regulated intestinal flora disturbance.
Conclusions: In summary, our findings revealed that HEL has a protective effect on LPS-induced ALI in rats, and its mechanism may be related to inhibiting TLR4/ NF-κB/NLRP3 signaling pathway and improving intestinal flora disturbance.

Objective: To explore the effect of acupuncture treatment on cerebral ischaemia-reperfusion injury (CIRI) and reveal the underlying mechanism of the effect based on nuclear receptor coactivator 4 (NCOA4) mediated ferritinophagy.
Methods: Sprague-Dawley male rats were divided into four groups: the sham group, model group, acupuncture group, and sham acupuncture group. After 2 h of middle cerebral artery occlusion (MCAO), reperfusion was performed for 24 h to induce CIRI. The rats were treated with acupuncture at the Neiguan (PC6) and Shuigou (GV26) acupoints. Their neurological function was evaluated by taking their Bederson scores at 2 h after ischaemia and 24 h after reperfusion. Triphenyltetrazolium chloride staining was applied to assess the cerebral infarct volume at 24 h after reperfusion. The malondialdehyde (MDA) and ferrous iron (Fe2+) levels were observed after 24 h of reperfusion using an assay kit. Western blotting was performed to detect the expression of NCOA4 and ferritin heavy chain 1 (FTH1) at 24 h after reperfusion. Moreover, the colocalization of ferritin with neurons, NCOA4 with microtubule-associated protein 1 light chain 3 (LC3), and NCOA4 with ferritin was visualized using immunofluorescence staining.
Results: Acupuncture significantly improved neurological function and decreased cerebral infarct volume in the acupuncture group. Following CIRI, the expression of NCOA4, LC3 and FTH1 was increased, which enhanced ferritinophagy and induced an inappropriate accumulation of Fe2+ and MDA in the ischaemic brain. However, acupuncture dramatically downregulated the expression of NCOA4, LC3 and FTH1, inhibited the overactivation of ferritinophagy, and decreased the levels of MDA and Fe2+.
Conclusions: Acupuncture can inhibit NCOA4-mediated ferritinophagy and protect neurons against CIRI in a rat model.

Objective: To examine the nephroprotective mechanism of modified Huangqi Chifeng decoction (, MHCD) in immunoglobulin A nephropathy (IgAN) rats.
Methods: To establish the IgAN rat model, the bovine serum albumin, lipopolysaccharide, and carbon tetrachloride 4 method was employed. The rats were then randomly assigned to the control, model, telmisartan, and high-, medium-, and low-dose MHCD groups, and were administered the respective treatments via intragastric administration for 8 weeks. The levels of 24-h urinary protein, serum creatinine (CRE), and blood urea nitrogen (BUN) were measured in each group. Pathological alterations were detected. IgA deposition was visualized through the use of immunofluorescence staining. The ultrastructure of the kidney was observed using a transmission electron microscope. The expression levels of interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and transforming growth factor-β1 (TGF-β1) were examined by immunohistochemistry and quantitative polymerase chain reaction. Levels of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and nuclear factor-kappa B (NF-κB) P65, were examined by immunohistochemistry, Western blotting, and quantitative polymerase chain reaction.
Results: The 24-h urine protein level in each group increased significantly at week 6, and worsen from then on. But this process can be reversed by treatments of telmisartan, and high-, medium-, and low-dose of MHCD, and these treatments did not affect renal function. Telmisartan, and high-, and medium-dose of MHCD reduced IgA deposition. Renal histopathology demonstrated the protective effect of high-, medium-, and low-dose of MHCD against kidney injury. The expression levels of MCP-1, IL-6, and TGF-β1 in kidney tissues were downregulated by low, medium and high doses of MHCD treatment. Additionally, treatment of low, medium and high doses of MHCD decreased the protein and mRNA levels of TLR4, MyD88, and NF-κB.
Conclusions: MHCD exerted nephroprotective effects on IgAN rats, and MHCD regulated the expressions of key targets in TLR4/MyD88/NF-κB signaling pathway, thereby alleviating renal inflammation by inhibiting MCP-1, IL-6 expressions, and ameliorating renal fibrosis by inhibiting TGF-β1 expression.

Objective: To evaluate the efficacy of Qidong Huoxue decoction (,QDHX) in treating acute lung injury and acute respiratory distress syndrome (ALI/ARDS) when used as an adjunctive treatment.
Methods: ALI/ARDS patients admitted to our medical intensive care unit were randomly allocated to the control group or the QDHX group and received standard therapy. The QDHX group received QDHX (50 mL per day for 14 d) orally or via a gastric tube. The primary outcome was measured according to Traditional Chinese Medicine (TCM) syndrome scores, with partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2) levels as the secondary outcome.
Results: A total of 73 patients completed the study (36 in the TCM and 37 in the conventional group), and their records were analyzed. After 14-d treatment, the TCM group showed a significant decrease in TCM syndrome scores (P < 0.05) and increased PaO2/FiO2 levels (P < 0.05). The therapeutic effect of integrated Chinese and western medicine was more significant than that of Western Medicine alone. No serious side effects were observed.
Conclusions: Our study results show that QDHX in combination with conventional drug therapy can significantly reduce some clinical symptoms in patients with ALI/ARDS.

Objective: To assess the long-term effectiveness of Huangqi (Radix Astragali Mongolici, HQ)-based Traditional Chinese Medicine (TCM) in the treatment of diabetic peripheral neuropathy (DPN).
Methods: Nine databases were searched to retrieve available randomized controlled trials that compared HQ-based TCM and Western Medicines in the treatment of DPN. The methodological quality of the included studies was assessed using the Cochrane bias risk tool, and RevMan 5.4 was used for data analysis. The effect estimates of interest were risk ratio (RR), mean difference (MD) or standardized mean difference (SMD) with 95% confidence interval (CI).
Results: The results from 48 available studies assessing 3759 patients demonstrated that cases administered HQ-based TCM [RR = 1.30, 95% CI (1.21, 1.40), P < 0.000 01] or HQ-based TCM combined with Western Medicines [RR = 1.25, 95% CI (1.19, 1.31), P < 0.000 01] exhibited higher total efficacy rates than individuals who received Western Medicine alone. The results showed that the HQ-based TCM group had decreased Toronto Clinical Scoring System scores [MD =-1.50, 95% CI (-1.83, -1.17), P < 0.000 01], and reduced serum interleukin 6 [SMD = -0.57, 95% CI (-0.87, -0.27), P = 0.0002] and tumor necrosis factors-α levels [SMD = -0.60, 95% CI (-0.95, -0.25), P = 0.0009]. In addition, both HQ-based TCM and HQ-based TCM combined with Western Medicine increased nerve conduction velocity and decreased glycaemia compared with Western Medicine alone. In terms of blood lipids, oxidative stress and adverse drug reactions, there were no significant differences between the HQ-based TCM groups and the Western Medicine control group.
Conclusion: The current Meta-analysis revealed that HQ-based TCM yields higher efficacy and safety than Western Medicine alone for the treatment of DPN, although further well-designed RCTs are required to validate these findings.
目的评估以黄芪为基础的中药治疗糖尿病周围神经病变(DPN)的长期疗效:方法:检索了九个数据库,以检索现有的随机对照试验,这些试验比较了以黄芪为基础的中药和西药治疗 DPN 的效果。使用 Cochrane 偏倚风险工具评估了纳入研究的方法学质量,并使用 RevMan 5.4 进行了数据分析。效果估计值为风险比(RR)、平均差(MD)或标准化平均差(SMD)及 95% 置信区间(CI):48项研究共评估了3759名患者,结果表明,与单独接受西药治疗的患者相比,服用以HQ为基础的中药[RR = 1.30,95% CI (1.21,1.40),P < 0.000 01]或以HQ为基础的中药联合西药[RR = 1.25,95% CI (1.19,1.31),P < 0.000 01]的患者总有效率更高。结果显示,以 HQ 为基础的中药组降低了多伦多临床评分系统评分[MD =-1.50, 95% CI (-1.83, -1.17), P < 0.000 01],降低了血清白细胞介素 6 [SMD = -0.57, 95% CI (-0.87, -0.27), P = 0.0002]和肿瘤坏死因子-α水平[SMD = -0.60, 95% CI (-0.95, -0.25),P = 0.0009]。此外,与单纯西医治疗相比,以 HQ 为基础的中医治疗和以 HQ 为基础的中医治疗联合西医治疗均能提高神经传导速度并降低血糖。在血脂、氧化应激和药物不良反应方面,以 HQ 为基础的中药组与西药对照组之间没有显著差异:目前的 Meta 分析表明,以 HQ 为基础的中医药治疗 DPN 比单纯西药治疗具有更高的疗效和安全性,尽管还需要进一步设计良好的 RCT 来验证这些研究结果。

Objective: To investigate the effectiveness and safety of Jiawei Xiaoyao pill (,JXP) in the treatment of symptoms associated with premenstrual syndrome (PMS).
Methods: A total of 144 regularly menstruating women with PMS were recruited at 8 sites in China from August 2017 to December 2018, and randomized to receive either a JXP or a matching placebo (12 g/d, 6 g twice a day) for 3 menstrual cycles. The primary indicator was the reduced Daily Record of Severity of Problems (DRSP) scores in the luteal phase after 3 months of treatment. The safety outcomes included clinical adverse events (AEs), adverse reactions (ARs), changes in vital signs, and laboratory tests.
Results: JXP surpassed the placebo in reducing DRSP scores (psychological/somatic dysfunction) in the luteal phase over 3 menstrual cycles of treatment (PFAS = 0.002, PPPS = 0.001). Additionally, there were no significant differences in the incidence of AEs, severe AEs, withdrawal due to AEs and ARs between the two groups (all P > 0.05), and no clinically significant adverse medical events related to the test drug observed.
Conclusions: JXP was superior to the placebo in relieving the symptoms associated with PMS, which signified that JXP may be effective, safe, and well-tolerated as an alternative therapy.

Objective: To formulate the first clinical practice guideline for the treatment of cough using Chinese medicine based on the grading of recommendations assessment, development, and evaluation (GRADE) systematic approach, including clinical evidence, evaluation of ancient literature, and expert consensus.
Methods: In the process of development, the regulation of "evidence-based, consensus-assisted, and empirical" was followed, and a comprehensive systematic approach of recommendation assessment, GRADE, evidence-based evaluation, expert consensus, and the Delphi method was used. In the process of guideline development, evidence-based evaluation of ancient literature was included for the first time, and clinical evidence was fully integrated with clinical expert consensus.
Results: The clinical practice guidelines for the treatment of cough with Chinese herbal medicine were developed after a comprehensive consideration of evidence-based evaluation and expert opinions. The guideline recommendations focused on recommending herbal compound decoctions and Chinese patent medicines for cough in different conditions. Based on the GRADE systematic approach, we conducted an evidence-based evaluation of the recommended Chinese patent medicines one by one; meanwhile, the expert consensus method was used to unify the recommendations of both.
Conclusion: Based on clinical evidence, ancient literature evaluation, and expert consensus, a clinical practice guideline for Traditional Chinese Medicine (TCM) in the treatment of cough was developed, providing the first current clinical practice guideline for domestic and foreign TCM and Western medicine practitioners, especially respiratory professionals at home and abroad.

Objective: To investigate the effects of emodin on alkali burn-induced corneal inflammation and neovascularization.
Methods: The ability of emodin to target vascular endothelial growth factor receptor 2 (VEGFR2) was predicted by molecular docking. The effects of emodin on the invasion, migration, and proliferation of human umbilical vein endothelial cells (HUVEC) were determined by cell counting kit-8, Transwell, and tube formation assays. Analysis of apoptosis was performed by flow cytometry. CD31 levels were examined by immunofluorescence. The abundance and phosphorylation state of VEGFR2, protein kinase B (Akt), signal transducer and activator of transcription 3 (STAT3), and P38 were examined by immunoblot analysis. Corneal alkali burn was performed on 40 mice. Animals were divided randomly into two groups, and the alkali-burned eyes were then treated with drops of either 10 μM emodin or phosphate buffered saline (PBS) four times a day. Slit-lamp microscopy was used to evaluate inflammation and corneal neovascularization (CNV) in all eyes on Days 0, 7, 10, and 14. The mice were killed humanely 14 d after the alkali burn, and their corneas were removed and preserved at -80 ℃ until histological study or protein extraction.
Results: Molecular docking confirmed that emodin was able to target VEGFR2. The findings revealed that emodin decreased the invasion, migration, angiogenesis, and proliferation of HUVEC in a dose-dependent manner. In mice, emodin suppressed corneal inflammatory cell infiltration and inhibited the development of corneal neovascularization induced by alkali burn. Compared to those of the PBS-treated group, lower VEGFR2 expression and CD31 levels were found in the emodin-treated group. Emodin dramatically decreased the expression of VEGFR2, p-VEGFR2, p-Akt, p-STAT3, and p-P38 in VEGF-treated HUVEC.
Conclusion: This study provides a new avenue for evaluating the molecular mechanisms underlying corneal inflammation and neovascularization. Emodin might be a promising new therapeutic option for corneal alkali burns.

Objective: To explore the anti-inflammatory components and mechanism of the non-volatile ingredients of patchouli.
Methods: High performance liquid chromatography-heated electron spray ionization-high resolution mass spectroscope (HPLC-HESI-HRMS) was used to analyze the chemical constituents of the non-volatile ingredients of patchouli. The anti-inflammatory activity of ingredients was evaluated using lipopolysaccharide (LPS) induced RAW264.7 cell inflammation model, and the anti-inflammatory mechanism was investigated using multivariate statistical analysis of cell metabolomics.
Results: The non-volatile ingredients of patchouli were characterized by HPLC-HESI-HRMS, and 36 flavonoids and 18 other components were identified. These ingredients of patchouli not only had a good protective effect on the LPS-induced inflammation model of RAW264.7 cells, but also regulated the expression levels of arginine, L-leucine, cholesterol, fructose and sorbitol by down-regulating arginine metabolism, aminoacyl-tRNA biosynthesis, polyol/sorbitol pathway, so as to reduce inflammation and reduce cell damage.
Conclusion: The non-volatile ingredients of patchouli had good anti-inflammatory effect and exerted its curative effect by regulating endogenous metabolic pathway to reduce inflammatory response.
