Effect of acupuncture treatment on nonketotic hyperglycemic hemichorea-hemiballismus: a case report.

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.

This study, aiming at finding biomarkers which can assist in the diagnosis of respiratory syncytial virus (RSV) pneumonia and analyzing the metabolic pathways of anti-RSV activity of Scutellaria baicalensis Georgi (SG)., explores the improvement effect of SG on mice models infected by RSV with the metabolomics technology based on UPLC-Q-Exactive HF X-MS. Mice models affected by RSV are established by nasal drip method and the changes of body weight, rectal temperature and pathological damage of lung tissue are evaluated. The lung tissue samples of mice in each group are collected and analyzed by UPLC-Q-Exactive HF X-MS. The differential metabolites of SG drug intervention are explored by metabolomics technology, and the metabolic pathways regulated by SG are analyzed. The results show that SG can significantly improve the pathological state of the lung tissue of the mice and make its body weight and rectal temperature tend to be normal. In the lung tissue samples, 46 biomarkers, such as guanine, L-asparagine, and arachidonic acid, are screened for disease development in RSV model mice. SG improved RSV infection by recalling 22 potential biomarkers, such as uric acid, arachidonic acid, and alanine. The 22 potential markers mainly involved 11 abnormal metabolic pathways, including phenylalanine, tyrosine, and tryptophan biosynthesis, and arachidonic acid metabolism, alanine, aspartic acid and glutamate metabolism are closely related to the five metabolic pathways. SG improves RSV-infected mice mainly by regulating amino acids, lipids, cofactors and vitamins and nucleotide metabolites. All animal experiments were conducted under the guidance and approval of the Animal Ethics Review Committee of Shandong University of Traditional Chinese Medicine.

Objective:To investigate the risk factors of gout and establish a columnar graph model to predict the risk of gout development.Methods:A total of 1 032 Han Chinese men attending the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University, People′s Hospital of Xinjiang Uygur Autonomous Region, and the First Affiliated Hospital of Xinjiang Medical University from 2018 to 2020 were selected as study subjects and divided into training set(722 cases)and validation set(310 cases)by simple random sampling method in the ratio of 7∶3. General information and biochemical indices of the subjects were collected. The collected information was used to assess the risk of gout prevalence. LASSO regression analysis of R Studio software was used to screen the best predictors, and was introduced to construct a column line graph model for predicting gout risk using receiver operating characteristic(ROC)curves, and the Hosmer-Lemeshow test was used to assess the discrimination and calibration of the column line graph model. Finally, decision curve analysis(DCA)was performed using the rmda program package to assess the clinical utility of the model in validation data.Results:Age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio were risk factors for gout( P<0.05). The column line graph prediction model based on the above five independent risk factors had good discrimination(AUC value: 0.923 for training set validation and 0.922 for validation set validation)and accuracy(Hosmer-Lemeshow test: P>0.05 for validation set validation); decision curve analysis showed that the prediction model curve had clinical practical value. Conclusion:The nomogram model established by combining age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio indicators can predict the risk of gout more accurately.

Effect and Safety of Acupuncture for Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis of 21 Randomised Controlled Trials / 中国结合医学杂志

OBJECTIVE@#To evaluate the effects of acupuncture on hypoglycaemic outcomes in type 2 diabetes mellitus (T2DM).@*METHODS@#PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from inception up to July 2020, to identify randomised controlled trials (RCTs) that enrolled patients with T2DM and compared acupuncture combined with antidiabetic drugs to antidiabetic drugs alone. The primary outcomes were haemoglobin A1c (HbA1c) and fasting blood glucose (FBG). The secondary outcomes included 2-h blood glucose (2hBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), and acupuncture-related adverse events. Mean difference (MD) and 95% confidence interval (CI) were used as the effect measure in the meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.@*RESULTS@#Twenty-one RCTs (n=1,188) were included. The meta-analytic results showed that the acupuncture group had greater reductions in FBG (MD -6.46 mg/dL, 95% CI -11.95 to -0.98; moderate-quality evidence) and HOMA-IR (MD -1.23, 95% CI -2.16 to -0.31; low-quality evidence), but comparable changes in HbA1c (MD -0.39%, 95% CI -0.84 to 1.61; very-low-quality evidence), 2hBG (MD -4.99 mg/dL, 95% CI -20.74 to 10.76; low-quality evidence), and FINS (MD -1.32 µIU/mL, 95% CI -3.76 to 1.12; low-quality evidence). No data on the incidence of diabetic complications were found. All acupuncture-related adverse events reported were mild.@*CONCLUSIONS@#The current evidence suggests that acupuncture, as a complementary therapy to antidiabetic drugs, has a small but statistically significant effect on decreasing FBG and improving insulin resistance. The effects of acupuncture on HbA1c, 2hBG, and FINS remain uncertain. Acupuncture is generally safe in patients with mild diabetes. More evidence for the long-term effects of acupuncture on T2DM is needed. (Trial registration No. CRD42018115639).

Xinglou Chengqi Decoction improves neurological function in experimental stroke mice as evidenced by gut microbiota analysis and network pharmacology / 中国天然药物

The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction (XCD) based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion (MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke (IS) to deplete the gut microbiota. High-throughput 16S rDNA gene sequencing, metabonomics technique, and flow multifactor technology were used to analyze bacterial communities, SCFAs and inflammatory cytokines respectively. Finally, as a supplement, network pharmacology and molecular docking were applied to fully explore the multicomponent-multitarget-multichannel mechanism of XCD in treating IS, implicated in ADME screening, target identification, network analysis, functional annotation, and pathway enrichment analysis. We found that XCD effectively improved neurological function, relieved cerebral infarction and decreased the neuronal apoptosis. Moreover, XCD promoted the release of anti-inflammatory factor like IL-10, while down-regulating pro-inflammatory factors such as TNF-α, IL-17A, and IL-22. Furthermore, XCD significantly increased the levels of short chain fatty acids (SCFAs), especially butyric acid. The mechanism might be related to the regulation of SCFAs-producing bacteria like Verrucomicrobia and Akkermansia, and bacteria that regulate inflammation like Paraprevotella, Roseburia, Streptophyta and Enterococcu. Finally, in the network pharmacological analysis, 51 active compounds in XCD and 44 intersection targets of IS and XCD were selected. As a validation, components in XCD docked well with key targets. It was obviously that biological processes were mainly involved in the regulation of apoptotic process, inflammatory response, response to fatty acid, and regulation of establishment of endothelial barrier in GO enrichment. XCD can improve neurological function in experimental stroke mice, partly due to the regulation of gut microbiota. Besises, XCD has the characteristic of "multi-component, multi-target and multi-channel" in the treatment of IS revealed by network pharmacology and molecular docking.

[Molecular regulatory mechanisms of hypoxia-inducible factor and interventional effect of Chinese herbal medicine].

Hypoxia-inducible factors(HIFs)are the key transcription factors that sense and regulate cellular oxygen concentration in vivo. HIF-1 is composed of 2 subunits,α and ß,in which,the molecular regulatory mechanism of HIF-1α involves the main processes of its degradation and activation. The degradation of HIF-1α is regulated by oxygen-dependent pathways,including "von hippel-lindau protein(pVHL)-dependent pathway" and "pVHL-independent pathway". The activation of HIF-1α is regulated by oxygen-independent pathways,including mammalian target of rapamycin(mTOR)/eukaryotic initiation factor 4 E-binding protein 1(4 EBP1)/HIF-1α pathway,phosphatidylinositol 3-kinase(PI3 K)/proteirrserinc-threonine kinases(Akt)/HIF-1α pathway and silent information regulator1(Sirt1)/HIF-1α pathway. In recent years,based on the molecular regulatory mechanism of HIFs,Roxadustat,a new drug for the treatment of renal anemia has been developed. Besides, some macromolecular substances with similar pharmacological effect to HIFs have been found in the extracts from Chinese herbal medicine(CHM),such as emodin,notoginseng triterpenes,honokiol and clematichinenoside. These natural macromolecular substances play the regulatory roles in inflammatory response,epigenetic modification and auto-phagy. It is worth noting that,for common hypoxic-related diseases including diabetic kidney disease,HIFs-mediated "pyroptosis" may be a new target of CHMs for clearing dampness and heat and its representative classical prescriptions(Ermiao Pills)in treating inflammatory injury in cells and tissues.

Berberine diminishes cancer cell PD-L1 expression and facilitates antitumor immunity

Programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) blocking therapy has become a major pillar of cancer immunotherapy. Compared with antibodies targeting, small-molecule checkpoint inhibitors which have favorable pharmacokinetics are urgently needed. Here we identified berberine (BBR), a proven anti-inflammation drug, as a negative regulator of PD-L1 from a set of traditional Chinese medicine (TCM) chemical monomers. BBR enhanced the sensitivity of tumour cells to co-cultured T-cells by decreasing the level of PD-L1 in cancer cells. In addition, BBR exerted its antitumor effect in Lewis tumor xenograft mice through enhancing tumor-infiltrating T-cell immunity and attenuating the activation of immunosuppressive myeloid-derived suppressor cells (MDSCs) and regulatory T-cells (Tregs). BBR triggered PD-L1 degradation through ubiquitin (Ub)/proteasome-dependent pathway. Remarkably, BBR selectively bound to the glutamic acid 76 of constitutive photomorphogenic-9 signalosome 5 (CSN5) and inhibited PD-1/PD-L1 axis through its deubiquitination activity, resulting in ubiquitination and degradation of PD-L1. Our data reveals a previously unrecognized antitumor mechanism of BBR, suggesting BBR is small-molecule immune checkpoint inhibitor for cancer treatment.

Mechanism of PI3K/Akt Signaling Pathway in Affecting Growth of Esophageal Cancer Cell and Research Progress of Intervention of Traditional Chinese Medicine / 中国实验方剂学杂志

Esophageal cancer is one of the malignant tumors with a high morbidity and mortality in China. According to China's latest cancer report released by the National Cancer Center in 2019, the number of people suffering from esophageal cancer reached 246 000 in 2015, and the death toll reached 188 000. How to effectively treat esophageal cancer and improve the survival rate of patients is one of the most urgent problems in the field of medicine. Phosphatidylinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is one of the most important signaling pathway for regulating cell survival, differentiation and apoptosis in the body. It also plays an important role in the occurrence and mechanism of various cancers. Recent studies have shown that the activation of PI3K/Akt signaling pathway is an important factor in regulating proliferation, apoptosis, cycle arrest, migration and invasion of esophageal cancer cells. The long-term clinical observation found that traditional Chinese medicine has a stable effect in the treatment of esophageal cancer and little side effects, especially in improving the quality of life of cancer patients and prolonging the survival period of patients. At present, it is a research hotspot to intervene this signal pathway with traditional Chinese medicine in the treatment of esophageal cancer, so as to explore its mechanism of action on esophageal cancer. This paper focused on literatures in CNKI and PubMed databases from 2009 to 2019, with PI3K/Akt signaling pathway, esophageal cancer and miRNA as the key words. A total of 226 literatures were retrieved, and 61 literatures relating to traditional Chinese medicine, esophageal cancer, miRNA and PI3K/Akt signaling pathway were sorted out and summarized. This paper reviewed the mechanism of PI3K/Akt signaling pathway in esophageal cancer, the relationship between miRNA and PI3K/Akt signaling pathway and esophageal cancer, and how traditional Chinese medicine can regulate the expressions of relevant proteins in PI3K/Akt signaling pathway to inhibit cell proliferation, affect cell growth cycle, induce cell apoptosis, inducing cell autophagy, inhibit tumor invasion and metastasis, inhibit angiogenesis. Finally, it can improve esophageal cancer to provide theoretical basis and scientific basis for the treatment of esophageal cancer with traditional Chinese medicine.

Objective:To investigate the therapeutic effect and possible mechanism of four types of Chinese herbal moisturizers made in laboratory for atopic dermatitis induced by 2，4-dinitrofluorobenzene （DNFB） in mice. Method:According to the body weight， BALA/c mice were randomly divided into normal group， model group， blank cream group （moisturizer A）， Shaoyao Gancaotang group （moisturizer B）， Shaoyao Gancaotang with Portulacae Herba，Ginseng Radix et Rhizoma and Honeysuckle Stem group （moisturizer C）， and Shaoyao Gancaotang with Ginseng Radix et Rhizoma and Honeysuckle Stem group （moisturizer D） ， with the dose of 25 g·kg-1 per day， as well as tacrolimus ointment group of 3 g·kg-1 per day， with 10 to 12 mice in each group. Except the normal group， the mice in the other groups were treated with 0.5% DNFB in the hair removal skin of back， 100 μL each for 7 days. Starting from the 7th day， each group was given the appropriate skin cream for external use intervention， once per day， for 15 consecutive days， except for the normal and the model groups. The animal body mass was measured once a week， and the animal back skin was graded three times a week， and the skin lesion score was recorded. After the mice were killed， the left and right ears were taken， the weight of both ears was punched and the degree of swelling was calculated. The back skin was fixed and stained with hematoxylin-eosin（HE） method， and then pathologic examination was conducted to observe and score the pathological changes of mouse back skin. Blood was obtained after the last dose and enzyme-linked immunosorbent assay （ELISA） was used to determine the immunoglobulin（Ig）E content in serum. Western blot was used to measure the expression of signal transduction and activator of transcription 3 （STAT3）， phosphorylation （p）-STAT3 in the skin tissue. Result:Compared with the normal group， the body mass decreased continuously， a series of inflammatory changes such as erythema， edema， dryness， desquamation and callus exfoliation and so on occurred in the modeling area， and the skin lesion score increased significantly in the model group. Additionally， the cuticle of ear skin was thickened and the degree of ear swelling was obviously increased in the model group. Microscopically， the occurred changes in the model mice included the local necrosis of the epidermis， epidermal thickening， epidermal hyperplasia， and the hyperkeratosis and hypokeratosis in the cuticle， as well as the subcutaneous inflammatory cell infiltration and so on. Furthermore， the content of serum IgE andthe expression of p-STAT3 in skin tissues increased significantly in the model group. Compared with the model group， the body mass of mice in group C and D was significantly increased （P<0.01）， and the skin lesion status score was decreased （P<0.05，P<0.01）.The degree of auricle swelling was significantly reduced in group B， C and D compared with that in the model group （P<0.01）.The degree of skin necrosis and defect and epidermal hyperplasia of mice in moisturizer C group was significantly reduced compared with that in model group （P<0.05，P<0.01）. Serum IgE levels of mice in group C and D were significantly lower than those in the model group （P<0.05，P<0.01）. The expression of p-STAT3 protein in skin tissues of mice in moisturizer C group was significantly lower than that in model group （P<0.05）. Conclusion:The moisturizers B， C and D all have certain therapeutic effect on atopic dermatitis， among which moisturizers C has the most obvious therapeutic effect. The possible mechanism may be that it reduces the level of inflammatory cytokines by inhibiting the increase of serum IgE content and the phosphorylation of STAT3.

This review illustrates recent studies of the use of LT in patients with ND and highlights its potential for clinical applications. The literature was collected from PubMed through June 2020. Selected studies were primarily English articles or articles that could be obtained with English abstracts and Chinese main text. Articles were not limited by type. Additional potential publications were also identified from the bibliographies of identified articles and the authors' reference libraries. The identified literature suggests that LT is a safe and convenient physical method of treatment. It may alleviate sleep disorders, depression, cognitive function, and other clinical symptoms. However, some studies have reported limited or no effects. Therefore, LT represents an attractive therapeutic approach for further investigation in ND. LT is an effective physical form of therapy and a new direction for research into treatments for ND. However, it requires further animal experiments to elucidate mechanisms of action and large, double-blind, randomized, and controlled trials to explore true efficacy in patients with ND.

Reporting quality of randomized controlled trials of acupuncture for cancer pain / 中国针灸

Based on the internationally-recognized Consolidated Standards for Reporting of Trials (CONSORT) statement and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA), the reported quality of randomized controlled trials (RCTs) of acupuncture for cancer pain during last 10 years were evaluated. The RCTs of acupuncture for cancer pain were searched by computer. The English databases included PubMed and EMbase while the Chinese databases included CNKI, Wanfang, VIP and SinoMed. The publication date of the literature was from March 2009 to March 2019. As a result, 22 Chinese RCTs and 13 English RCTs were included. According to the CONSORT statement, among the Chinese studies, 1 RCT reported primary and secondary outcomes, 8 RCTs reported randomization, none of RCTs reported allocation concealment and blind method, and 4 RCTs reported baseline data; among the English studies, 8 RCTs reported primary and secondary outcomes, 8 RCTs reported randomization, 6 RCTs reported described allocation concealment, 7 RCTs reported blind method, and 13 RCTs reported baseline data. According to the STRICTA statement, among the Chinese studies, 17 RCTs reported the name of acupoints, 6 RCTs reported depth of insertion, 17 RCTs reported acupuncture response sought, and none of RCTs reported the qualifications of acupuncturists; among the English studies, 12 RCTs reported the name of acupoints, 7 RCTs reported depth of insertion, 8 RCTs reported acupuncture response sought, and 7 RCTs reported the qualifications of acupuncturists. The Chinese RCTs have more detailed description of acupuncture intervention and theory, but not enough attention is paid to methodological description such as randomization, blindness, data analysis. On the other hand, the English RCTs have better description of methodology, but the description of theory and details of acupuncture is relatively weak. It is concluded that more efforts were needed to further improve the clinical trial design according to the CONSORT statement and STRICTA statement to improve the quality of clinical evidence.
