Objective: To evaluate the efficacy and safety of Suhuang Zhike capsule in the adjuvant treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Methods: The database including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Chinese Biomedical Literature Database and Wanfang Data was searched. The retrieval time was from database establishment to May 2021. Randomized controlled trial (RCT) of Suhuang zhike capsule adjuvant treatment for AECOPD was included. The quality of the studies was independently evaluated and cross-checked by two reviewers, and Meta-analysis was performed by using RevMan5.3 software.

Results: Thirteen RCT results were included with a total sample number of 1195 cases, including 597 in the experimental group and 598 in the control group. The results showed that Suhuang zhike capsule adjuvant treatment of AECOPD could improve the total clinical effect rate compared with conventional treatment. Suhuang zhike capsule adjuvant treatment could improve forced vital capacity (FVC), forced expiratory volume in one second (FEV), FEV/FVC, peak expiratory flow (PEF) and other pulmonary function indexes; decrease C-reactive protein (CRP), white blood cells, neutrophils and other infectious indicators; besides, the 1-year recurrence rate of the disease was decreased (all 0.05).

Conclusions: Suhuang Zhike capsule can improve the lung function and clinical efficacy of AECOPD, thus increasing the exercise endurance, and reducing the infection and recurrence rate in AECOPD patients.

Objective: To study the efficacy of Xiaoyao capsule in improving the clinical symptoms of sleep and mood disorders during recovery from coronavirus disease 2019 (COVID-19).

Methods: The study cohort comprised 200 patients with sleep and mood disorders during recovery from COVID-19. Patients were randomized into the control group and the experimental group in a 1:1 ratio by blocked randomization. The patients received either Xiaoyao capsule (experimental group) or a placebo Xiaoyao capsule (control group) for 2 weeks. The improvements in the Traditional Chinese Medicine (TCM) syndrome scales, total effective rates, and disappearance rates of irritability, anxiety, and poor sleep were compared between the two groups.

Results: The TCM syndrome pattern scales, total effective rates, and disappearance rates of irritability, anxiety, and poor sleep did not significantly differ between the experimental group versus the control group in the full analysis set and the per protocol set after 1 and 2 weeks of treatment ( > 0.05).

Conclusions: Xiaoyao capsule do not significantly improve the clinical symptoms of sleep and mood disorders in patients in recovery from COVID-19.

Objective: To evaluate the efficacy of Baishao Luoshi decoction (, BD) on synaptic plasticity in rats with post stroke spasticity (PSS), and to study the mechanism behind the action.

Methods: The PSS model of rat was established by middle cerebral artery occlusion (MCAO). The neurological deficit symptoms were evaluated by modified neurological deficit score (mNSS). Muscle tension were evaluated by Modified Ashworth score (MAS). Transmission electron microscopy (TEM) was used to observe the synaptic ultrastructure. The expression of synaptic plasticity-related protein brain derived neurotrophic factor (BDNF), growth associated protein-43 (GAP43), synaptophysin (p38) and microtubule-associated protein 2 (MAP2) in the brain tissue around the infarct were detected by Western blotting.

Results: We found that mNSS were significantly improved and limb spasticity was ameliorated treated by BD. The thickness of postsynaptic density and the synaptic curvature increased significantly. The expression of synaptic plasticity-related protein BDNF, GAP43, p38, MAP2 in the brain tissue around the infarct were raised remarkably after treated by BD.

Conclusions: Alleviating PSS by BD may be related to rescuing the synaptic plasticity, which provides a probable new therapeutic method for PSS.

Objective: To integrate Meta-analysis and bioinformatics strategies in the preliminary exploration of the potential mechanism of Yinyanghuo () and its extract in treating chronic obstructive pulmonary disease (COPD).

Methods: First, Meta-analysis was carried out. The Chinese and English literature of Yinyanghuo () in treating COPD was searched using the systematic strategy of combining subject words with free words. The included studies were evaluated by the SYRCLE risk bias assessment tool, after which the review manager software was used to combine the effect quantities for statistical analysis. Then, based on bioinformatics technology, the active ingredients and their targets of Yinyanghuo () were screened, and the intersection genes were obtained by mapping and comparing with the targets of COPD. The "medicinal materials-compounds-targets model" was constructed, and the key pathways were annotated. Finally, the core target was docked with important compounds.

Results: A total of 8 studies were included in the Meta-analysis. The results showed that the Yinyanghuo (Herba Epimedii Brevicornus) group could significantly down-regulate pro-inflammatory factors such as tumor necrosis factor-α (TNF-α) and interleukin (IL)-8 and increase the expression of anti-inflammatory factors and antioxidant factors such as IL-10 and phospho-protein kinase B (p-AKT) in the COPD model (all P < 0.05). A total of 23 active components and 102 corresponding target genes of Yinyanghuo (Herba Epimedii Brevicornus) were obtained by bioinformatics technology, among which 17 compounds and 63 targets were closely related to COPD. The results of enrichment analysis mainly included TNF signaling pathway, phosphoinositide 3-kinase (PI3K)/Akt signaling pathway, cancer signaling pathway, and other inflammatory reactions, oxidative stress, and tumor-related pathways. The molecular docking results showed that the binding energy fractions of the top five components of 24-epicampesterol with 10 core targets such as IL-6 were all less than ﹣5.0 kcal/mol, suggesting good binding ability.

Conclusions: Meta-analysis and bioinformatics results indicated that the therapeutic effect of Yinyanghuo () and its components on COPD might be related to antagonizing inflammation and oxidative stress. The above findings provide a preliminary basis for the development of Yinyanghuo () as a natural drug for preventing and treating COPD.

Objective: To investigate the efficacy of scalp acupuncture Yikang therapy on Baihui (GV20), Sishencong (EX-HN1), Zhisanzhen, Niesanzhen, on neurobehavior in young rats with cerebral palsy based on Notch signaling pathway.

Methods: Thirty 7-day-old rats were randomly divided into sham, model and acupuncture, 10 rats in each group. The cerebral palsy model was established by the accepted modeling method, the acupuncture group selected "Baihui (GV20)", "Sishencong (EX-HN1)", "Zhisanzhen" and "Niesanzhen" for intervention 24 h after the model was made. The body masses were recorded before and after the treatment, respectively. After the intervention, the rats were subjected to suspension experiment, slope experiment, tactile stimulation experiment and Morris water maze experiment. After the end of the experiment, the morphological changes of hippocampal histology were observed by hematoxylin-eosin (HE) staining under light microscope, and the expression of Notch1, Notch3 and Hes5 were detected by Western blot and quantitative real-time polymerase chain reaction (PCR).

Results: The changes in body mass of the rats in each group were different; in behavioral experiments, compared with the sham, the suspension time of the model was shortened, the slope experiment, tactile stimulation experiment, and escape latency time were prolonged, and the number of platform crossing was reduced in the model, compared with the model, the suspension time of the acupuncture was prolonged, the slope experiment, tactile stimulation experiment, and escape latency time were shortened, and the number of platform crossing times was increased; HE staining showed severe hippocampal damage in the model and reduced hippocampal damage in the acupuncture. Western Blot and real-time fluorescence quantitative PCR showed that the expression of Notch1, Notch3 and Hes5 were increased in the model and the expression of Notch1, Notch3, Hes5 in acupuncture were decreased.

Conclusions: Scalp acupuncture Yikang therapy may improve neurobehavior and reduce brain injury in rats with cerebral palsy by downregulating the expression of Notch1, Notch3, and Hes5.

Objective: To evaluate the effectiveness of cycling in combination with electroacupuncture in treatment of post-stroke hemiplegia patients at National Hospital of Acupuncture, Vietnam.

Methods: The study was designed as a single-centre, outcome-assessor-blinded parallel randomised controlled trial with 120 post-stroke hemiplegia patients randomly assigned into two groups: electroacupuncture plus cycling (CT group) and electroacupuncture (AT group). Patients were assessed before and after the treatment (using muscle grading, modified Rankin, Barthel, Orgorozo scores and electromyography). Statistical Man-Whitney U test, and Fisher's exact tests were used to compare between CT and AT groups.

Results: The results reported statistically significant improvement in motor function in patients suffering from hemiplegia following ischemic stroke in both CT and AT groups. Patients in CT group experienced a greater improvement compared to those in AT group including better muscle contraction (increased frequency and amplitude of electromyography and increased muscle grading scale); increased recovery (Orgogozo scale), increased independency (Barthel scale) and decreased disability (Modified Rankin scale) (< 0.01).

Conclusions: Combination with cycling training significantly improves the recovery of post-stroke patients treated with electroacupuncture.

Objective: To investigate the mechanism of deficiency syndrome (YDS) by analyzing the liver metabolomic characteristics of three different deficiency rat models METHODS: Following the TCM etiology, for clinical features and pathological manifestations of modern medicine, three kinds of animal models of deficiency were induced and replicated. Totally 48 Sprague-Dawley (SD) male rats were randomly divided into blank group, irritation induced model group, Fuzi-Ganjiang induced model group, and thyroxine-reserpine induced model group. After successful development of model, the ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry was carried out to detect metabolites in each group. The metabolites of rat liver were analyzed for the characteristics of their biomarkers. The pathway enrichment analysis and metabolic network construction were performed through various online databases including Metabolite Biology Role, Human Metabolome Database, MetaboAnalyst, and Kyoto Encyclopedia of Genes and Genomes.

Results: The SD rats in the experimental group showed symptoms like less weight gain, reduced diet and water intake, high body temperature, increased liver and kidney indexes, and abnormal liver and kidney tissue morphology. Moreover, the rats showed high increased levels of serum cyclic adenosine monophosphate, estradiol, alanine transaminase, and aspartate aminotransferase and decreased levels of cyclic guanosinc monophosphate and testosterone. We found four key interrelated metabolic pathways in the liver tissue metabolomics, including the biosynthesis of pantothenic acid and coenzyme A, and metabolism of alpha-linolenic acid metabolism, glycerophospholipid metabolism, and sphingolipid.

Conclusion: The liver and kidney YDS is closely related to the biosynthesis of pantothenic acid and CoA and abnormal metabolism of α-linolenic acid, glycerophospholipid, and sphingolipid in SD rats.

Objective: To investigate the effect and mechanisms of Danzhi Jiangtang capsule (, DJC) on renal injury in streptozotocin (STZ)-induced diabetes of rats.

Methods: Sprague-Dawley rats were fed with high fat diet for 6 weeks followed by streptozotocin (STZ, 35 mg/kg) injection. These rats were then treated with DJC (270, 540 and 1080 mg/kg) daily for 8 weeks.

Results: A combination of high fat diet and STZ significantly increased blood glucose creatinine, urea nitrogen, and urine albumin in rats. Meanwhile, the glomerular and tubular lesions were observed in rats fed with high fat diet and injected with STZ. These biochemical and pathological changes were significantly attenuated by DJC treatments in a dose-dependent manner. Mechanistically, DJC treatments significantly decreased toll-like receptor 4 (TLR4), mitogen-activated protein kinase (MAPK), and nuclear factor-κB (NF-κB) signals in the kidney of rats fed with high fat diet and injected with STZ. Terminal deoxynucleotidyl transferase dUTP nick end labeling staining and caspase-8 levels showed that renal apoptosis was increased in rats fed with high fat diet and injected with STZ, and this was attenuated by DJC treatments.

Conclusions: DJC treatments protect against diabetic kidney disease, and the mechanism may be closely related to downregulation of TLR4/MAPK/NF-κB pathways and apoptosis. This study provides further evidence of using DJC as a potential therapeutic option for diabetic kidney disease.
