Amniotic membrane mesenchymal stromal cell-derived secretome in the treatment of acute ischemic stroke: A case report.

BACKGROUND: Stroke is the second and third leading cause of death and disability, respectively. To date, no definitive treatment can repair lost brain function. Recently, various preclinical studies have been reported on mesenchymal stromal cells (MSCs) and their derivatives and their potential as alternative therapies for stroke. CASE SUMMARY: A 45-year-old female suffered an acute stroke, which led to paralysis in the left upper and lower limbs. The amniotic membrane MSC-derived secretome (MSC-secretome) was intravenously transplanted once a week for 4 wk. MSC-secretome-regulated regulatory T cells were investigated for the beneficial effects. The clinical improvement of this patient was accompanied by an increased frequency of regulatory T cells after transplantation. CONCLUSION: Intravenous administration of MSC-secretome can potentially treat patients who suffer from acute ischemic stroke.

Coaxial radiography guided puncture technique for percutaneous transforaminal endoscopic lumbar discectomy: A randomized control trial.

BACKGROUND: The coaxial radiography-guided puncture technique (CR-PT) is a novel technique for endoscopic lumbar discectomy. As the X-ray beam and the puncturing needle are maintained in a parallel and coaxial direction, the X-ray beam can be used to guide the trajectory angle, facilitating the choice of the puncture site and providing real-time guidance. This puncture technique offers numerous advantages over the conventional anterior-posterior and lateral radiography-guided puncture technique (AP-PT), especially in cases of herniated lumbar discs with a hypertrophied transverse process or articular process, high iliac crest, and narrowed intervertebral foramen. AIM: To confirm whether CR-PT is a superior approach to percutaneous transforaminal endoscopic lumbar discectomy compared to AP-PT. METHODS: In this parallel, controlled, randomized clinical trial, herniated lumbar disc patients appointed to receive percutaneous endoscopic lumbar discectomy treatment were recruited from the Pain Management Department of the Affiliated Hospital of Xuzhou Medical University and Nantong Hospital of Traditional Chinese Medicine. Sixty-five participants were enrolled and divided into either a CR-PT group or an AP-PT group. The CR-PT group underwent CR-PT, and the AP-PT group underwent AP-PT. The number of fluoroscopies during puncturing, puncture duration (min), surgery duration (min), VAS score during puncturing, and puncture success rate were recorded. RESULTS: Sixty-five participants were included, with 31 participants in the CR-PT group and 34 in the AP-PT group. One participant in the AP-PT group dropped out due to unsuccessful puncturing. The number of fluoroscopies [median (P25, P75)] was 12 (11, 14) in the CR-PT group vs 16 (12, 23) in the AP-PT group, while the puncture duration (mean ± SD) was 20.42 ± 5.78 vs 25.06 ± 5.46, respectively. The VAS score was 3 (2, 4) in the CR-PT group vs 3 (3, 4) in the AP-PT group. Further subgroup analysis was performed, considering only the participants with L5/S1 segment herniation: 9 patients underwent CR-PT, and 9 underwent AP-PT. The number of fluoroscopies was 11.56 ± 0.88 vs 25.22 ± 5.33; the puncture duration was 13.89 ± 1.45 vs 28.89 ± 3.76; the surgery duration was 105 (99.5, 120) vs 149 (125, 157.5); and the VAS score was 2.11 ± 0.93 vs 3.89 ± 0.6, respectively. All the above outcomes demonstrated statistical significance (P < 0.05), favoring the CR-PT treatment. CONCLUSION: CR-PT is a novel and effective technique. As opposed to conventional AP-PT, this technique significantly improves puncture accuracy, shortens puncture time and operation time, and reduces pain intensity during puncturing.

Effectiveness and safety of acupuncture for angina pectoris: An overview of systematic reviews.

Background: The number of systematic reviews meta-analyses (SRs/MAs) on the effectiveness of acupuncture for angina pectoris (AP) is increasing. Due to the inconsistent conclusions and unknown quality of these SRs/MAs, this overview aimed to systematically evaluate and synthesize the existing SRs/MAs, attempting to provide more reliable evidence for the effectiveness and safety of acupuncture in the treatment of AP. Methods: SRs/MAs were searched via eight databases from inception to March 14, 2022. The risk of bias was evaluated using the Risk of Bias in Systematic reviews (ROBIS) tool. The quality of the methodology, reporting, and evidence were assessed by the Assess Systematic Reviews 2 (AMSTAR-2), the Preferred Reporting Item for Systematic Review and Meta-analysis for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system, respectively. Results: Sixteen SRs/MAs were included and fifteen SRs/MAs were considered being of critically low quality according to AMSTAR-2. Only three SRs/MAs were rated at low risk of bias. No study reported all the items listed in the PRISMA-A checklist. No high-quality evidence with GRADE assessment was found. With the low-quality evidence, acupuncture combined with other interventions was superior to monotherapy (medications or Chinese medicine) in the angina symptom and electrocardiogram recovery. No adverse effects owing to acupuncture were reported. Conclusions: Owing to the lack of high-quality evidence provided by the current SRs/MAs, the effectiveness of acupuncture for AP still warrants further proof. Further researches with more critical design and methodology are needed for providing more convincing evidence.

[Relationship between accumulation of autotoxins and soil fertility factors under long-term continuous cropping of cucumber in solar greenhouse]. / æ—¥å ‰æ¸©å®¤é»„ç“œé•¿æœŸè¿žä½œè‡ªæ¯’ç‰©è´¨ç´¯ç§¯ä¸ŽåœŸå£¤è‚¥åŠ›å› å­çš„å ³ç³».

In this study, we investigated the effects of long-term continuous cucumber cropping on phenolic acids in rhizosphere soil, as well as their link to soil chemical characteristics, enzyme activities, and microbiological activities, using rhizosphere soil from the 2nd, 6th, 10th, 14th, 18th, 20th, 24th, and 26th round of cucumber cultivation in solar greenhouse. The results showed that contents of phenolic acids increased significantly with increasing continuous cropping rounds. The increase amount per round of total phenolic acid was significantly higher in the early stage (0-2 rounds) and late stage (20-26 rounds) than middle stage (10-14 rounds) of continuous cropping. Soil nutrient contents were enriched, while invertase enzyme activity and microbial activities were decreased. Redundancy analysis showed that organic matter, total phosphorus, total nitrogen, available nitrogen, microbial biomass carbon and microbial metabolic entropy were main soil fertility factors correlating with the accumulation of phenolic acids. Results of structural equation model showed that soil phosphorus enrichment directly led to the accumulation of phenolic acids, and that nitrogen enrichment indirectly facilitated the accumulation of phenolic acids by altering the activity of microorganisms. As a result, proper nitrogen and phosphorus fertilizers application would reduce the accumulation of phenolic acids and alleviate the cucumber continuous cropping obstacles.

An Open-Label Exploratory Clinical Trial Evaluating the Effects of GLS (Coptidis Rhizoma-Evodiae Fructus 2 : 1) on Fibroblast Growth Factor 21 in Patients with Nonalcoholic Fatty Liver Disease.

Methods: In a 12-week, open-label, exploratory clinical trial, 126 NAFLD patients were randomly divided into the GLS group (lifestyle intervention plus GLS) or the polyene phosphatidylcholine (PPC) group (lifestyle intervention plus PPC). Random numbers generated by DPS software were used in combination with opaque, sealed envelopes for allocation concealment. At baseline as well as at the end of the study, anthropometric parameters, glucose, lipids, hepatic enzymes, and FGF 21 were measured, with hepatic fat accumulation assessed by ultrasound (US) and US-based controlled attenuation parameter (CAP). Results: 119 patients completed the study. Baseline parameters did not significantly differ between the two groups (P > 0.05). Compared with PPC, GLS decreased more significantly in hepatic fat accumulation, body weight index, waist circumference, waist-to-hip ratio, serum glucose, total cholesterol, triglyceride, low-density lipoprotein cholesterol, alanine transaminase, aspartate transaminase, gamma-glutamyl transferase, and FGF 21 (P < 0.05). The effects of GLS on waist circumference, waist-to-hip ratio, CAP, and gamma-glutamyl transferase (GGT) were positively correlated with serum FGF 21 (r = 0.343, 0.342, 0.315, and 0.374, respectively, P < 0.05). The GGT and FGF-21 changes were also confirmed by multiple linear regression analysis (B, 0.777; 95% CI: 0.307-1.247, P < 0.05). Conclusion: GLS has a significant hepatoprotective effect on NAFLD patients, causing a decrease in FGF-21 secretion in response to the damage itself.

Electroacupuncture at Zusanli ameliorates the autistic-like behaviors of rats through activating the Nrf2-mediated antioxidant responses.

OBJECTIVE: Emerging evidence suggests that acupuncture plays a neuroprotective role in autism. This study aimed to explore the effect of electroacupuncture at Zusanli (ST36) on autistic-like behaviors and the underlying mechanism. METHOD: Pregnant rats were administered with valproic acid (VPA) on gestational day 12.5 to induce an autism spectrum disorder (ASD) model. The pups were given electroacupuncture at ST36 daily from postnatal day (PND) 28-48. On PND28, the adenoviral vector containing small interfering RNA Nrf2 (Ad-siRNA-Nrf2) was injected into the prefrontal cortex of rats. The behavioral analysis was performed on PND 44-48. On PND48, the animals were euthanized and the brains were collected for further detection. Nissl staining was performed to detect neuronal viability. The biochemical markers of oxidative stress were subsequently measured. RESULT: Electroacupuncture at ST36 ameliorated the locomotor activity, social behavior, spatial learning and memory and repetitive behavior compared with ASD rats. It was notable that the electroacupuncture decreased oxidative stress markers in the tissues of prefrontal cortex, enhanced translocation of nuclear factor erythroid2-related factor2 (Nrf2) from cytoplasm to nucleus, and up-regulated the levels of NADP(H) quinone oxidoreductase (NQO1) and heme oxygenase (HO-1). However, these effects induced by electroacupuncture at ST36 were abolished after injection of Ad-siRNA-Nrf2. CONCLUSION: These data suggested that electroacupuncture at ST36 protected nerve function in ASD rats through Nrf2 activation and the antioxidant response.

Tai Chi and other mind-body interventions for cancer-related fatigue: an updated systematic review and network meta-analyses protocol.

INTRODUCTION: Fatigue is one of the most common symptoms in patients with cancer and is responsible for a reduced quality of life. There is a strong evidence base for mind-body interventions (MBIs) to manage cancer-related fatigue (CRF). However, the efficacy of Tai Chi and other MBIs in the treatment of CRF remains controversial. METHODS AND ANALYSIS: We will perform a systematic review and network meta-analyses (NMAs) that aim to assess the effects of Tai Chi and other MBIs in patients with CRF. The following databases will be searched from their inception to 1 August 2021: PubMed, EMBASE, Scopus, OVID, Web of Science, Cochrane Central Register of Controlled Trials, the China National Knowledge Infrastructure, China Science and Technology Journal Database, Chinese Biomedical Database and Wan Fang Digital Journals. We will include randomised controlled trials that compare MBIs with no treatment, placebo and usual care in the treatment of CRF. The primary outcome will be changes in the fatigue state as evaluated by validated scales. We will perform a Bayesian NMA to analyse all the evidence for each outcome. The surface under the cumulative ranking curve and the mean ranks will be used to rank the various treatments. We will assess the quality of evidence contributing to network estimates of outcomes using the Grading of Recommendations Assessment, Development and Evaluation system framework. ETHICS AND DISSEMINATION: This NMAs will be disseminated through publication in a peer-reviewed journal. Since no individual patient data will be involved in the review, ethics approval and concerns about privacy are not needed. PROSPERO REGISTRATION NUMBER: CRD42021244999.

Effect of acupoint catgut embedding in chronic fatigue syndrome patients: A protocol for systematic review and meta-analysis.

BACKGROUND: Chronic fatigue syndrome (CFS) is a relatively complex and disabling illness with a substantial economic burden and functional impairment. Until now, many CFS patients lack appropriate healthcare. Acupoint catgut embedding is an effective and emerging alternative therapy for CFE. With this research, we endeavor to investigate the effect and safety of ACE for CFS. METHODS: Eight databases will be searched from inception to December 2020: PubMed, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chong-Qing VIP database, and Wan-fang database. We regard studies as eligible for inclusion if they were RCTs done in CFS patients, compare acupoint catgut embedding to another treatment strategy, and report fatigue changes at the end of the intervention period. Two independent reviewers complete the study selection, data extraction, and the risk of bias assessment. We assess pooled data using a random-effects model through Revman software (v.5.3) and Stata (version 15.0). ETHICS AND DISSEMINATION: Ethics approval is not required because the individual patient data will not be involved, with no privacy concerns. This systematic review and meta-analysis will provide a reference for CFS patients and clinicians on the non-drug interventions. We will publish and disseminate the results of this review in a peer-reviewed journal or relevant conference. OSF REGISTRATION NUMBER: 10.17605/OSF.IO/7SHD9 (https://osf.io/7shd9).

Proteomics for Early Diagnosis of Alzheimer's Disease and Prevention and Treatment with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Alzheimer's disease （AD） is currently the most common neurodegenerative disorder characterized by insidious onset and slow progression， which has seriously endangered the physical and mental health of the elderly. It is therefore very important to carry out the early diagnosis and active prevention and treatment. Biomarkers are essential for its diagnosis. Looking for ideal biomarkers is helpful for early identification of this disease. The prevention and treatment of AD with traditional Chinese medicine （TCM） has always been a hot spot in scientific research due to good safety and small side effects. Proteomics is an advanced omics technology that enables the identification and characterization of proteins. Its high-throughput， dynamic， and comprehensive characteristics coincide with the concept of holism emphasized in TCM diagnosis and treatment， which makes proteomics suitable for identifying biomarkers with diagnostic potential， objectifying TCM syndrome differentiation and treatment， and developing new Chinese medicinal prescriptions for precise and targeted treatment. Although the proteomics technology is becoming increasingly mature， it still faces challenges in the diagnosis and treatment of AD. There exist such shortcomings as high heterogeneity and poor reproducibility of protein omics results， requirement for the combination with other advanced omics technologies， and high sequencing cost. In the future， the protein omics technology should be constantly updated and optimized to boost precision medicine， disease prevention， and drug research and development. This paper retrieved related articles from Pubmed， China National Knowledge Infrastructure （CNKI） and reviewed the application of proteomics in the early diagnosis of AD and its prevention and treatment with TCM in recent years， in order to provide reference for the in-depth study of AD diagnosis as well as its prevention and treatment with TCM.

Development of Novel Shortenings Structured by Ethylcellulose Oleogels.

A novel shortening was developed based on oleogels structured by ethylcellulose (EC) polymers. The texture and oil retention ability of EC oleogels were characterized against the level of viscosity of different grades of EC, as well as the rheological properties in relation to the polymer structure in the gel network. EC100, which has an average viscosity of 100 cP, was selected as the most suitable organogelator at 4% (w/w) in combination with base oil (30% degree of saturation by mixing palm stearin and soybean oil) to form the shortening. Triglyceryl monostearate (TMS) was found to be the most effective emulsifier as evidenced by its ability to strengthen air-incorporation ability of the shortening while creating evenly distributed fine crystals in the system. The EC100 shortening was able to create breads with excellent specific volume, indicating its ability to incorporate air bubbles during dough development and to serve as an antifirming agent to create bread with stable soft texture. PRACTICAL APPLICATION: In the present study, we attempted to create a novel shortening by employing oleogels structured by ethylcellulose (EC), the most promising gelation agent to develop gel network capable of replacing solid fat without health concerns. EC oleogels in shortening with detailed characterization of the shortening microstructure in relation to its functional properties was elucidated. The optimal formulation in relation to preservation of gel structure and consistency with enhanced moisture and air retention were also identified.

[Effects of selenium fertilization on selenium availability in rice soil.] / 施硒对水稻土壤硒有效性的影响.

Selenium (Se) is easy to be fixed in acidic rice soil of South China, and thus its availability is low. The aim of this study was to investigate the influence of Se fertilizer on Se availability in rice rhizosphere and non-rhizosphere soils. The results showed that Se application increased yield and rice Se concentration. The water soluble, exchangeable, Fe/Mn oxide-bound, organic matter/sulfide-bound, and residual Se contents of the rhizosphere soil were lower than those of the non-rhizosphere soil. There was no significant difference in the migration coefficient of Se between the rhizosphere and non-rhizosphere soils. Se application had no significant effect on the migration coefficient of Se between roots and leaves but improved its migration coefficient between leaves and grains. The secretion of organic acids was increased by the application of 0.5 mg·kg-1 and decreased by the application of 1.0 and 5.0 mg·kg-1 Se. The secretion of organic acids had no significant effect on the rhizosphere soil pH. The pH of rhizosphere soil was higher than that of the non-rhizosphere soil, while the application of Se decreased the pH of the rhizosphere soil. With the increases of Se application, the intensity of the infrared absorption of clay mineral (kaolinite) in the rhizosphere soil showed an increasing trend. In this study, most of the Se was transformed into forms that were difficult to be absorbed and utilized by rice and difficult to move to rhizosphere soil. The enhancement of soil Se availability following the secretion of organic acids was not due to its effects on soil pH.

The synthesis and anti-metastatic effects of optical isomers of ionone alkaloid 9-(N,N-dimethyl)-4,7-megastigmedien-3-one.

Ionone alkaloid 9-(N,N-dimethyl)-4,7-megastigmedien-3-one (compound 1) is a new anti-metastatic natural product. However, it was previously reported as optical isomers mixture. Herein, the optical isomers (6a-6d) of compound 1 were synthesized. The absolute configurations of 6a-6d were determined by ECD experiments and calculated spectra with time-dependent density functional theory (TDDFT). The anti-metastatic effects of the optical isomers were examined by transwell assay. These results revealed that compound 6a had potential anti-metastatic activity with an IC50 value of 0.512 ±â€¯0.093 µM.

Relationship between Tissue Distributions of Modified Wuzi Yanzong Prescription () in Rats and Meridian Tropism Theory.

OBJECTIVE: To investigate the relationship between tissue distributions of modified Wuzi Yanzong prescription (, MWP) in rats and meridian tropism theory. METHODS: A high-performance liquid chromatography with Fourier transform-mass spectrometry (HPLC-FT) method was used to identify the metabolites of MWP in different tissues of rats after continued oral administration of MWP for 7 days. The relationship between MWP and meridian tropism theory was studied according to the tissue distributions of the metabolites of MWP in rats and the relevant literature. RESULTS: Nineteen metabolites, mainly flavanoid compounds, were detected in the different rat tissues and classified to each herb in MWP. Further, it was able to establish that the tissue distributions of the metabolites of MWP were consistent with the descriptions of meridian tropism of MWP available in literature, this result might be useful in clarifying the mechanism of MWP on meridian tropism. In the long run, these data might provide scientific evidence of the meridian tropism theory to further promote the reasonable, effective utilization, and modernization of Chinese medicine. CONCLUSION: The tissue distributions of MWP in vivo were consistent with the descriptions of meridian tropism of MWP.

[Study on effect of Jiangtang decoction on AGEs-RAGE and oxidative stress in KK-Ay mice].

To elucidate the efficacy of Jiangtang decoction(JTD) on AGEs-RAGE and oxidative stress in type 2 diabetic model KK-Ay mice. Fifty KK-Ay mice were randomly divided into 5 groups as follows： model group, metformin group, low-dose, medium-dose and high-dose of JTD group, with 10 C57BL/6J as normal group. All groups are orally administrated with equal distilled water, 250 mg•kg⁻¹ metformin hydrochloride, 2, 4,8 g•kg⁻¹ JTD, equal distilled water respectively, once per day for 12 weeks. Alanine aminotransferase(ALT), creatinine(CREA), urea nitrogen(BUN),advanced glycation end products(AGEs) and receptor of glycation end products(RAGE) in blood or urine were measured during the experiments. Furthermore, on the day of the sacrifice, kidney was collected, and electronic microscopy and immunohistochemistry were performed to evaluate the protective renal effect of JTD. In addition, the levels of AGEs, RAGE, Cata-lase(CAT) and superoxide dismutase(SOD) were assessed by Western blot, Real-time PCR or ELISA to analyze the efficacy of JTD. This study demonstrated that JTD might protect kidney of KK-Ay by down-regulating the expression of AGEs, RAGE and oxidative stress.

[Study of effect of Humifuse Euphorbia Herb on alleviating insulin resistance in type 2 diabetic model KK-Ay mice].

[To explore the effect of Humifuse Euphorbia Herb ( HEH) on alleviating insulin resistance in type 2 diabetic KK-Ay mice. Totally 40 KK-Ay mice fed with high-fat diet were divided into four groups: the metformin group, the model group, the HEH low-dose group and the HEH high-dose group, and orally administrated with metformin hydrochloride (250 mg x kg(-1)), distilled water, humifuse euphorbia herb 1 g x kg(-1) and 2 g x kg(-1). Besides, C57BL/6J mice with ordinary feed were taken as the normal control group and orally administrated with equal distilled water. The oral administration for the five groups lasted for eight weeks. Before and after the experiment, weight, fasting glucose and insulin tolerance were determined. The morphological changes in pancreas were observed through hematoxylin-eosin (HE) staining on pancreatic tissue sections. The serum insulin, TNF-α, IL-6, adiponectin (ADPN) and leptin (LEP) were detected by ELISA. The results showed that HEH could reduce weight and fasting glucose in KK-Ay mice, alleviate hyperinsulinemia, reduce blood glucose-time AUC, increase 30-min blood glucose decline rate, relieve insulin resistance, significantly ameliorate the pathomorphological changes in pancreas in each group, decrease serum TNF-α, IL-6 and leptin levels in KK-Ay mice and rise serum ADPN level. This study proved that humifuse euphorbia herb can ameliorate the insulin resistance in KK-Ay mice, and its mechanism may be related to the effect on inflammatory factors and adipocytokines.

[Effect of 18-ß Glycyrrhetinic Acid on the Endoplasmic Reticulum of Nasal Epithelial Cells in Allergic Rhinitis Model Rats].

OBJECTIVE: To explore the effect of 18-ß glycyrrhetinic acid (GA) on the endoplasmic reticulum of nasal epithelial cells in allergic rhinitis (AR) model rats. METHODS: Totally 96 Wistar rats were randomly divided into the blank group, the AR model group, the loratadine group, the GA group, 24 in each group. AR models were established by peritoneally injecting ovalbumin (OVA). Morphological scoring was performed. GA at 21. 6 mg/kg was intragastrically administered to rats in the GA group. Nasal mucosal tissues were taken for electron microscopic examinations at the second, fourth, sixth, and tenth week after drug intervention. RESULTS: The overlapping score was 2.10 ± 0.45 in the blank group, 5.10 ± 0.56 in the loratadine group, 5.10 ± 0.56 in the AR model group, 5.20 ± 0.78 in the GA group, showing statistical difference when compared with the blank group (P < 0.01). Results under transmission electron microscope showed that the number of the endoplasmic reticulum increased in the AR model group, with obvious cystic dilatation, a lot of vacuole formation, and degranulation. A large number of free ribosomes could be seen in cytoplasm. With persistent allergen exposure, changes mentioned above was progressively aggravated in the endoplasmic reticulum of nasal mucosal epithelium in the AR model group. But the dilation of endoplasmic reticulum, vacuole formation, and degranulation were relieved in the GA group, and got close to those of the blank group. CONCLUSION: 18-ß GA could improve the expansion, vacuolization, and degranulation of the endoplasmic reticulum of nasal epithelial cells in AR model rats.

Experimental analysis on the main contents of Rhizoma gastrodiae extract and inter-transformation throughout the fermentation process of Grifola frondosa.

Gastrodin (GA), p-hydroxylbenzaldehyde (HBA), p-hydroxybenzyl alcohol (gastrodigenin, HA) and parishin not only are the major active ingredients of Rhizoma gastrodiae, but exist transformed relations from each other throughout the fermentation process of Grifola frondosa in this work. We had found that parishin (non-free gastrodin) almost could completely transformed into gastrodin (GA, free gastrodin) after R. gastrodiae alcohol extract was sterilized by moist heat (121 °C, 30 min), but before was added into submerged cultivation of G. frondosa. However, interestingly and importantly, gastrodin re-synthesized of parishin after R. gastrodiae alcohol extract's addition into submerged cultivation of G. frondosa. In addition, the reduction of p-hydroxylbenzaldehyde and p-hydroxybenzyl alcohol in G. frondosa fermentation process reconfirmed that the G. frondosa strain 51616 really could synthesize gastrodin into parishin by submerged fermentation. This paper firstly also reported G. frondosa's effects on R. gastrodiae.

Integration of traditional Chinese medicines and Western medicines for treating diabetes mellitus with coronary heart disease: a systematic review.

PURPOSE: Diabetes mellitus with coronary heart disease (DM with CHD) poses a health challenge to people in China and elsewhere in the world. In Traditional Chinese Medicine (TCM), DM with CHD is classified as a type of disease called Xiaoke and Xiongbi. In Asia, TCM has been used to treat Xiaoke and Xiongbi conditions for centuries, especially in China. In this study, it was evaluated whether integrated strategies incorporating both TCM and Western medicines (iTCWM) could improve the curative efficacy of DM with CHD. METHODS: An extensive search for randomized clinical trials (RCTs) published up to November 2011 in either English or Chinese about iTCWM for DM with CHD was conducted. All listings in PubMed, EMBASE, the Cochrane Library, CBM, CNKI, VIP, and the Wanfang database were included in the literature search. The quality of each trial was assessed using the Cochrane Reviewers' Handbook 5.0. Data analysis was performed by the RevMan 5.0 provided by the Cochrane Collaboration. RESULTS: After an initial selection of 207 articles, 21 RCTs and quasi-RCTs were ultimately included in the analysis for this study. All of these trials were conducted in China and published in Chinese journals. The methodological quality of the trials was low in most studies. Selection bias and measurement bias were common in all of the studies. A meta-analysis was not conducted, due to the poor quality of the available studies. CONCLUSIONS: The current state of the literature regarding the utility of iTCWM for the treatment of DM with CHD is inadequate. The poor quality of the available trials makes it difficult to draw any conclusions regarding the efficacy of iTCWM for the treatment of DM with CHD. This study highlights the paucity of reliable clinical evidence for iTCWM and the need for higher quality RCTs to be conducted in the future.

Kirenol exerts a potent anti-arthritic effect in collagen-induced arthritis by modifying the T cells balance.

Rheumatoid arthritis is characterized by the imbalance of T cells, which leads to increased pro-inflammatory and reduced anti-inflammatory cytokines. Modulating the balance among T cells is crucial for the treatment of RA. Kirenol is a major diterpenoid components of Herba Siegesbeckiae, which has been applied for arthritic therapy for centuries. Since prior research showed Kirenol exhibited anti-inflammatory effect in rats, in this study we have evaluated the effect and mechanism of bioactive Kirenol in a rat model of collagen-induced arthritis (CIA) on modulation of T cells. After immunization with bovine type II collagen (CII), Wistar rats were orally administered saline (CIA group), 2 mg/kg Kirenol or 2 mg/kg prednisolone daily for 30 days. The severity of arthritis was clinically and histologically assessed. The numbers of CD4⁺CD25⁺Foxp3⁺ T regulatory cells (Tregs) and IFNγ⁺CD4⁺ and IL4⁺CD4⁺ T cells were determined by flow cytometry, the mRNA expression level of Foxp3 was quantified by RT-PCR, cytokine levels were measured by ELISA and CII-induced cell proliferation was quantified in vitro. Kirenol significantly delayed the occurrence and reduced the disease severity of CIA. Histological analysis confirmed Kirenol suppressed joint inflammation and inhibited cartilage and bone destruction, compared to the CIA group. Kirenol also upregulated the mRNA expression of Foxp3, increased the numbers of CD4⁺CD25⁺Foxp3⁺ and IL4⁺CD4⁺ T cells, and reduced the number of IFNγ⁺CD4⁺ T cells. Kirenol reduced the levels of TNF-α, IL-17A and IL-6 in synovial fluid and TNF-α, IL-17A and IFN-γ in serum, and increased the serum levels of IL-4, IL-10 and TGF-ß1. In addition, Kirenol inhibited the ability of CII to induce splenocyte, PBMC and lymph node cell proliferation in vitro, compared to cells from CIA rats. In conclusion, these results suggest that Kirenol may be a potential immunosuppressant for the treatment for rheumatoid arthritis.
