Objective: To investigate the efficacy of electroacupuncture (EA) stimulating Zusanli (ST36) and Xuanzhong (GB39) on synovial angiogenesis in rats with adjuvant arthritis (AA).

Methods: AA models were established by bilateral injection of Freund's complete adjuvant (FCA) in male Sprague-Dawley rats. Three days after injection, rats were given EA at Zusanli (ST36) and Xuanzhong (GB39) acupoints, once every other day, for 16 d. The arthritis index score, paw volume, and hematoxylin-eosin (HE) staining was performed for each animal. Angiogenesis marker cluster of differentiation 34 (CD34) expression and synovial cell apoptosis in synovial tissue were observed. The levels of Notch1, hairy and enhancer of split homolog-1 (Hes1), transforming growth factor-beta (TGF-β) and basic fibroblast growth factor (bFGF) were subsequently detected.

Results: We found that EA significantly decreased arthritis index scores, paw volume, and HE staining scores. EA could significantly inhibit the expression of CD34, promoting apoptosis of synovial cells in the joint synovial tissue of AA rats. The expression of Notch1 signaling pathway proteins and mRNAs (Notch1, Hes1, TGF-β, and bFGF) were markedly downregulated by EA treatment.

Conclusions: These results prove that EA attenuates synovial angiogenesis by inhibiting the Notch1 signaling pathway in AA rat models. Based on our findings, we propose that EA is a promising complementary and alternative therapy in rheumatoid arthritis.

TanshinoneⅡA (TanⅡA) is a noteworthy lipophilic diterpene compound derived from the dried roots of the Traditional Chinese Medicine Danshen () that has various pharmacological properties, including anti-inflammatory, antibacterial, and antioxidative effects. Sepsis is a life-threatening organ dysfunction induced by a dysregulated host response to infection. Recently, increasing attention has been paid to sepsis-induced dysfunction of the intestine, car-diovascular system, lungs, kidneys, liver, and other organs. Experimental studies have shown that TanⅡA has therapeutic potential for sepsis-induced organ dysfunction owing to its anti-inflammatory, anti-apoptotic and regulatory effects on multiple signalling pathways. The purpose of this article is to evaluate the potential multiorgan protective effects of TanⅡA in sepsis.

Objective: To examine the protective effect of ginsenoside Rb1 (Rb1), the main component of Renshen (), on cardiomyopathy in db/db mice exposed to chronic intermittent hypoxia (CIH) and explore the potential underlying mechanism of Rb1 in treating diabetic cardiomyopathy (DCM).

Methods: The db/db mice were randomly separated into five groups: normal control group, model group, Rb1 20 mg/kg group, Rb1 40 mg/kg group, and glucagon-like peptide-1 (GLP-1) group. Mice were exposed to air-condition or CIH for 8 weeks, and Rb1 and GLP-1 were administrated before CIH exposure every day. Oral glucose tolerance test (OGTT), intraperitoneal insulin tolerance test (IPITT), total cholesterol (TC), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were detected to evaluate glycolipid metabolism. The level of insulin was detected by a mouse enzyme-linked immunosorbent assay (ELISA). Cardiac function was detected by echocardiography, and myocardial pathology was observed by hematoxylin-eosin and Masson staining. The expression of collagen Ⅰ and collagen Ⅲ was detected by immunohistochemistry. Adenosine monophosphate-activated protein kinase (AMPK)/Nrf2/heme oxygenase-1 (HO-1) signaling pathway was detected by Western blot and immunofluorescence.

Results: Rb1 treatment could improve glucose tolerance and the level of cardiac function indexes, and inhibit the level of oxidative stress indexes and the expression of collagen Ⅰ and collagen Ⅲ. Moreover, Rb1 treatment enhanced AMPK phosphorylation and increased Nrf2 and HO-1 expression.

Conclusion: Rb1 treatment alleviated CIH-induced diabetic cardiomyopathy and glycolipid metabolism disorders in db/db mice by inhibiting oxidative stress and regulating the AMPK/Nrf2/HO-1 signaling pathway.

Objective: To investigate the effectiveness and safety of Guilingji capsule (, GLJC) in treatment of Alzheimer's disease (AD) patients with kidney-marrow deficiency pattern (KMDP) compared with gingko extract tablets.

Methods: This is a secondary analysis of a large-scale multicenter randomized non-inferiority clinical trial. A total of 120 AD patients with KMDP were enrolled in this study. The participants were randomly categorized into two groups: (a) GLJC group ( = 60) and (b) gingko group ( = 60). The GLJC group was treated with GLJC and gingko extract mimetic tablets, whereas the gingko group received gingko extract tablets and mimetic GLJC. The data on the Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), Activities of Daily Living (ADL), and Chinese Medicine Symptom Scale (CM-SS) was evaluated at 0, 12, and 24 weeks of treatment. The serum levels of acetylcholine (Ach), acetylcholinesterase (AchE), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) in the participants were measured before and after 24 weeks of treatment. The safety was based on the incidence of adverse events.

Results: Both interventions significantly increased the MMSE scores of the participants and decreased their ADAS-Cog, ADL, and CM-SS scores ( < 0.01). Compared with the gingko group, the GLJC group had a higher effective rate of improvement in the symptoms of "amnesia" and "dull expression and slow thinking" at the 12th week and 24th week ( < 0.05, < 0.01). In the GLJC group, serum Bcl-2 levels were significantly increased at the 24th week ( < 0.05). Serum Bax and AchE levels of the two groups were significantly decreased at the 24th week ( < 0.01). No treatment-related adverse events were reported in the two groups.

Conclusions: GLJC is equivalent to the gingko extract tablets in terms of improving cognitive function and the quality of life in AD patients with KMDP and has good clinical efficacy and safety. When it comes to improving TCM symptoms and anti-aging, GLJC is even more advantageous.

Objective: To verify the hypothesis that electroacupuncture inhibits the hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis regulating the expression of glial fibrillary acidic protein (GFAP) in the hippocampus of acute myocardial ischemia (AMI) rats.

Methods: Sixty-six healthy male Sprague-Dawley rats were randomly divided into five groups: Sham, AMI (Model), electroacupuncture at Shenmen (HT7)-Tongli (HT5) segment (EA), non-acupoint electroacupuncture (Control), and Model + corticosterone (Model + CORT). AMI was induced occlusion of the left anterior descending coronary artery, followed by 3 d of electroacupuncture at Shenmen (HT7)-Tongli (HT5) segment. In the Control group, electroacupuncture was applied at points lying 5 and 10 mm from the base of the tail. The AMI + CORT group was injected with CORT (20 mg/kg) in saline. Hemorheology, electrocardiography (ECG), hematoxylin and eosin staining, and expression of glycogen phosphorylase BB (GPBB) and heart-type fatty acid-binding protein (H-FABP) were used to assess cardiac function. The effects of adrenocorticotropic hormone (ACTH) and CORT were evaluated by enzyme-linked immunosorbent assay. Protein expression in the Sham and Model groups were screened by tandem mass tag-based quantitative proteomics analysis. Protein expression was evaluated by Western blotting (vimentin and GFAP) and immunofluorescence staining (GFAP).

Results: Compared with the Sham group, the hemorheology indicators, heart rate, ECG-ST segment elevation, and GPBB and H-FABP levels were higher in Model rats. The EA group showed reductions in these indicators compared with the Model group. Similarly, in Model rats, the expression of ACTH and CORT were significantly increased compared with the Sham group. The EA group also showed reduced expression of ACTH and CORT. Importantly, proteomics analysis showed that vimentin was differentially expressed in Model rats. Compared with the Sham group, vimentin and GFAP expression in the hippocampus was increased in the Model group but decreased in the AMI + EA group. Additionally, intraperitoneal injection of CORT aggravated the expression of GPBB, H-FABP and GFAP.

Conclusions: Our results suggested that electroacupuncture may protect against cardiac injury induced by AMI through regulation of HPA axis hyperactivity, and that hippocampal GFAP may play an important role in the regulation.

Objectives: To observe the efficacy of Shenlian formula (SL formula, ), which consist of Huanglian () and Renshen (), in the treatment of type 2 diabetes mellitus (T2DM) and explore the effects on gut microbiota and serum inflammatory cytokines.

Methods: In a double-blind, randomized, placebo-controlled parallel-group clinical trial, 31 adults with T2DM were randomly allocated to receive the SL formula or placebo for 12 weeks. Body mass index (BMI), blood lipid indices, glycemic biomarkers including glycated hemoglobin (HbA1C), fasting plasma glucose (FPG), postprandial blood glucose (PBG), fasting insulin levels (FIL), fasting C-peptide (C-P), homoeostasis model assessment for insulin resistance (HOMA-IR) and inflammatory cytokines were assessed at baseline and 12 weeks. The contents of gut microbiota were determined by pyrosequencing of the V3-V4 regions of 16S rRNA genes.

Results: Sixteen cases were allocated in the treatment group and 15 in the placebo group. Compared with the placebo, SL formula resulted in a higher significant reduction in PBG [(?1.318 ± 0.772)(?0.008 ± 1.404) mmol/L, 0.003], BMI [(?0.611 ± 0.524)(0.957 ± 2.212) kg/m, 0.01], FIL [(?1.627 ± 6.268)(3.976 ± 6.85) μIU/mL, 0.02], HOMA-IR [(?0.530 ± 1.461)(1.511 ± 2.288), 0.006], and C-reactive protein (CRP) [(?1.307 ± 0.684)(0.828 ± 0.557) mg/L, 0.04]. In terms of gut microbiota, compared with the placebo, the SL formula resulted in a significant decrease in species richness and evenness.

Conclusions: The SL formula showed the efficacy to improve postprandial blood glucose, insulin resistance, BMI and CRP levels. In addition, it could reduce the total number, richness and evenness of species, meanwhile increase the abundance of probiotics to modulate the structure of gut microbiota in patients with T2DM. However, further studies are required for exploring the deeper mechanism of TCM on gut microbiota.

Objective: To evaluate the effectiveness and safety of Xuebijing injection (XBJ) on coronavirus disease 2019 (COVID-19) in patients.

Methods: Related studies on multiple biological databases and websites were searched up to December 11, 2021 without language and publication time restrictions. Review Manager V.5.3 and Stata 14 software were used for data analysis.

Results: Seven studies were finally included. The Metaanalysis showed that compared with the routine treatment alone, XBJ combined with the routine treatment can reduce the 28day mortality ( = 0.3, 95% : 0.12, 0.74), Creactive protein ( = -12.8, 95% : -23.13, 3.46), erythrocyte sedimentation rate ( = -9.32, 95% : -14.66, -3.98) and interleukin-6 (S = -0.6, 95% : -1.04, -0.17) levels and increase the leukocyte ( = 0.73, 95% : 0.42, 1.04) and lymphocyte count ( = 0.18, 95% : 0.07, 0.29) in peripheral blood; additionally, it has no obvious side effects ( = 1.11, 95% : 0.65, 1.9). There was no evidence that the XBJ combined therapy can improve the nucleic acid conversion rate and computed tomography improvement rate of COVID19 patients.

Conclusions: Preliminary evidence suggests that XBJ combined with routine treatment seems to be more effective than routine treatment for patients with COVID19. Limited by the number and quality of included papers, this finding still needs further validation by more studies.

Objective: To explore the mechanism by which Qinghua decoction regulates neuroendocrine inflammation in chronic nonbacterial prostatitis (CNP) model rats and provide an experimental basis for clinical treatment.

Methods: The rats were randomly divided into six groups: normal control, model, Qianlie Tongyu capsule, low-dose Qinghua decoction, medium-dose Qinghua decoction, and high-dose Qinghua decoction group with six rats in each group. Rats in each group were sacrificed on the 29th day of treatment, and blood and prostate tissues were collected. Serum levels of tumor necrosis factor-alpha and interleukins 1-beta, 6, 8, and 10 (TNF-α and IL-1β, -6, -8, and -10, respectively) were measured using enzyme-linked immunosorbent assay. The pathological changes in the rat prostate tissue in each group were observed under a light microscope. The expression levels of chromogranin A (CgA), nerve growth factor (NGF), and tyrosine kinase A (TrkA) were detected using reverse transcription quantitative polymerase chain reaction. Western blotting was used to detect protein expression of CgA, NGF, and TrkA.

Results: In the model group, the prostate capsule membrane and stroma were significantly dilated with more inflammatory cells infiltrating the stroma and perivessels. TNF-α, IL-1β, -6, and -8, CgA, NGF, and TrkA levels increased, whereas the content of IL-10 decreased, which was statistically significant compared to that in the normal control group ( < 0.05). Prostate tissue cells in the high-dose group were neatly arranged with no obvious inflammatory cell infiltration. When compared with the model group, the high-dose Qinghua decoction group showed a significant improvement in these indices ( < 0.05).

Conclusion: Qinghua decoction led to inhibition of pathological changes in the prostate tissue of rats with CNP, regulation of inflammatory cytokine expression, and inhibition in the expression of CgA, NGF, and TrkA. This mechanism may be primarily related to regulation of the CgA/NGF/TrkA signaling pathway mediated by various inflammatory factors.

Objective: To investigate the therapeutic action and mechanism of the Qizhi Jiangtang capsule (, QZJT) on diabetic kidney disease (DKD) treatment.

Methods: This experiment used db/db mice and podocytes (MPC5) to develop DKD model. Evaluation of the effect of the QZJT on db/db mice by testing urine and blood biochemical parameters (24-h urinary albumin, serum creatinine, blood urine nitrogen), pathological kidney injury, and podocyte integrity. Moreover, autophagosomes in podocytes of DKD mice and cultured podocytes were detected using electron microscopy. Additionally, Western blotting was applied to detect the expression of podocyte marker protein (podocin), autophagy-associated proteins, and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) signaling pathway changes and .

Results: QZJT significantly reduced urine protein, blood nitrogen urea, and serum creatinine and showed histological restoration of renal tissues. QZJT also significantly improved the down-regulation of podocin and foot fusion and effacement in db/db mice. QZJT increased autophagic vesicles in mice and cultured podocytes. QZJT also upregulated microtubule-associated protein 1 light chain 3-II (LC3-II) / (LC3-I) and Beclin-1 and downregulated phosphorylated-PI3K (p-PI3K), p-AKT, and p-mTOR in db/db mice and MPC5 cells. However, autophagy inhibitor 3-methyladenine partially alleviated the above effects in MPC5 cells.

Conclusions: These results showed that the QZJT can enhance podocyte autophagy and ameliorate podocyte injury in DKD by inhibiting the PI3K/AKT/mTOR signaling pathway.

Nonketotic hyperglycemic hemichorea-hemiballismus is a rare syndrome in the clinic, and treatment is often delayed. Hypoglycemic therapy is the most widely used and effective treatment, but some patients experience a slower improvement. Other symptomatic treatment medicines have some degree of side effects. Acupuncture treatment is beneficial for hemichorea-hemiballismus. A male patient, aged 59 years, first visited our hospital outpatient department due to motor agitation with involuntary movements of the right limb. He had a history of type 2 diabetes mellitus and poor blood glucose control. His serum glucose was 26.5 mmol/L (normal: 4.4-6.1 mmol/L), and magnetic resonance imaging demonstrated an irregular area of high signal intensity in T1-weighted imaging, low signal intensity on T2-weighted imaging, and high signal intensity in the left corpus striatum in T2-FLAIR imaging. Hospitalization was recommended for the patient. After ruling out other possibilities, he was eventually diagnosed with nonketotic hyperglycemic hemichorea-hemiballismus. Intensive glycemic control was immediately started with subcutaneous injection and acupuncture treatment at "governor vessel 13 acupoints", and the involuntary movements completely disappeared on the ninth day of hospitalization. The pathophysiology of nonketotic hyperglycemic hemichorea-hemiballismus is unclear. Different patient histories lead to different brain tissue conditions, and relapses and uncontrolled blood glucose add difficulties to treatment. According to Traditional Chinese Medicine theory, insufficient kidney essence leads to brain dystrophy and causes the symptoms of hemichorea-hemiballismus. Research evidence has shown that acupuncture at "governor vessel 13 acupoints" has a beneficial treatment effect on nonketotic hyperglycemic hemichorea-hemiballismus.
