Therapeutic effect of Duhuo Jisheng Decoction add-on Tui-na manipulation on osteoarthritis of knee: a randomized controlled trial.

BACKGROUND: Knee osteoarthritis (KOA) is a common degenerative joint condition that causes disability and pain in the elderly population. The prevalence of KOA among persons aged 63 or above is approximately 30%. Previous studies have reported the positive effects of Tui-na treatment and the Chinese herbal formula Du-Huo-Ji-Sheng Decoction (DHJSD) for KOA treatment. The current study aims to evaluate the add-on therapeutic effect of oral administration of DHJSD on KOA in addition to Tui-na. METHODS: We conducted a prospective, randomized, controlled clinical trial. Seventy study subjects with KOA were randomly assigned to the treatment and control groups in a 1:1 ratio. Both two groups received eight sessions of Tui-na manipulation for 4 weeks. The DHJSD was only administered to the study subjects in the treatment group. The primary outcome measure was rated using the WOMAC at the end of treatment (4 weeks). Secondary outcomes were assessed using EQ-5D-5L, a health-related quality of life with 5-level EQ-5D version at end of treatment (week 4) and follow-up (week 8). RESULTS: No statistically significant difference was found between two groups on WOMAC scores at the end of treatment. The mean WOMAC Pain subscale score was significantly lower in the treatment group than control group at week 8 follow up (mean difference, MD - 1.8, 95% CI - 3.5 to - 0.02, P = 0.048). The mean WOMAC Stiffness subscale score was significantly lower in the treatment group than in the control group at week 2 (MD 0.74, 95% CI 0.05 to 1.42, P = 0.035) and week 8 follow up (MD 0.95, 95% CI 0.26 to 1.65, P = 0.008). The mean EQ-5D index value was significantly improved in the treatment group than in the control group at week 2 (MD 0.17, 95% CI 0.02 to 0.31, P = 0.022). The analysis of WOMAC scores and EQ-5D-5L in both groups showed statistically significant improvement with time. No significant adverse effect was found during the trial. CONCLUSION: DHJSD may have an add-on effect in addition to Tui-na manipulation relieving pain and improving stiffness as well as quality of life (QOL) in patients with KOA. The combined treatment was generally safe and well tolerated. Trial registration The study was registered at the ClinicalTrials.gov (website: https://clinicaltrials.gov/ct2/show/NCT04492670 , registry number: NCT04492670), registered on 30 July 2020.

[Knowledge graph analysis of pyroptosis research in traditional Chinese medicine based on VOSviewer and CiteSpace].

To explore the research hotspots and frontier directions of pyroptosis in the field of traditional Chinese medicine(TCM), the authors searched CNKI and Web of Science for literature related to pyroptosis in TCM, screened literature according to the search strategy and inclusion criteria, and analyzed the publication trend of the included literature. VOSviewer was used to draw author cooperation and keyword co-occurrence network diagrams, and CiteSpace was employed for keyword clustering, emergence, and timeline view. Finally, 507 Chinese literature and 464 English literature were included, and it was found that the number of Chinese and English literature was increasing rapidly year by year. The co-occurrence of the authors showed that in terms of Chinese literature, there was a representative research team composed of DU Guan-hua, WANG Shou-bao and FANG Lian-hua, and for English literature, the representative research team was composed of XIAO Xiao-he, BAI Zhao-fang and XU Guang. The network visualization of Chinese and English keywords revealed that inflammation, apoptosis, oxidative stress, autophagy, organ damage, fibrosis, atherosclerosis, and ischemia-reperfusion injury were the primary research diseases and pathological processes in TCM; berberine, resveratrol, puerarin, na-ringenin, astragaloside Ⅳ, and baicalin were the representative active ingredients; NLRP3/caspase-1/GSDMD, TLR4/NF-κB/NLRP3, and p38/MAPK signaling pathways were the main research pathways. Keyword clustering, emergence, and timeline analysis indicated that the pyroptosis research in TCM focused on the mechanism of TCM monomers and compounds intervening in diseases and pathological processes. Pyroptosis is a research hotspot in the area of TCM, and the current discussion mainly focuses on the mechanism of the therapeutic effect of TCM.

A chemometric study on the identification of 5-methylfurfural and 2-acetylfuran as particular volatile compounds of oxidized fish oil based on SHS-GC-IMS.

Fish oil develops particular off-odors, mainly fishy odor, from the oxidation of its characteristic fatty acids, docosahexaenoic (DHA) and eicosapentaenoic (EPA). Anchovy oil (AO) was taken as representative of fish oils. This was compared to three vegetable oils with different fatty acid compositions, i.e. camellia, sunflower and linseed oil, and differential volatile compounds were identified by static-headspace gas-chromatography ion-mobility-spectrometry (SHS-GC-IMS) and orthogonal partial-least-squares discriminant analysis (OPLS-DA) during oxidation at 60 °C. Three groups of differential volatile compounds detected at higher concentrations in the AO were screened out and two compounds, identified as 5-methylfurfural and 2-acetylfuran, were characteristic to the AO and not found in the vegetable oils. They were formed from both EPA and DHA, only present in the AO, and their formation mechanisms were proposed. The contents of 5-methylfurfural and 2-acetylfuran increased linearly with the oxidation time and consequently they could be used as oxidative markers of fish oils.

[Comparison of chemical compositions of different parts of Xanthoceras sorbifolium seeds based on UHPLC-Q-Orbitrap HRMS].

Xanthoceras sorbifolium seeds have a wide range of applications in the food and pharmaceutical industries. To compare and analyze the chemical compositions of different parts of X. sorbifolium seeds and explore the potential value and research prospects of non-medicinal parts, this study used ultra-high-performance liquid chromatography quadrupole Orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) to detect the chemical composition of various parts of the seeds. A total of 82 components were preliminary identified from X. sorbifolium seeds, including 5 amino acids, 4 polyphenols, 3 phenylpropionic acids, 7 organic acids, 15 flavonoids, 6 glycosides, and 23 saponins. Mass spectrometry molecular networking(MN) analysis was conducted on the results from different parts of the seeds, revealing significant differences in the components of the seed kernel, seed coat, and seed shell. The saponins and flavonoids in the seed kernel were superior in terms of variety and content to those in the seed coat and shell. Based on the chromatographic peaks of different parts from multiple batches of samples, multivariate statistical analysis was carried out. Four differential components were determined using HPLC, and the average content of these components in the seed kernel, seed coat, and seed shell were as follows: 0.183 6, 0.887 4, and 1.440 1 mg·g~(-1) for fraxin; 0.035 8, 0.124 1, and 0.044 5 mg·g~(-1) for catechin; 0.032 9, 0.072 0, and 0.221 5 mg·g~(-1) for fraxetin; 0.435 9, 2.114 7, and 0.259 7 mg·g~(-1) for epicatechin. The results showed that catechin and fraxetin had relatively low content in all parts, while fraxin had higher content in the seed coat and seed shell, and epicatechin had higher content in the seed kernel and seed coat. Therefore, the seed coat and seed shell possess certain development value. This study provides rapid analysis and comparison of the chemical compositions of different parts of X. sorbifolium seeds, which offers an experimental basis for the research and clinical application of medicinal substances in X. sorbifolium seeds.

A Chinese Medicine Formula (Bushen Huoxue Tongluo) for the Treatment of Chronic Subjective Tinnitus: A Study Protocol for a Pilot, Assessor-Blinded, Randomized Clinical Trial.

Background: Tinnitus is a common problem worldwide. There is still no effective method to cure it. Traditional Chinese medicine (TCM) may be a potentially effective treatment approach for tinnitus. However, there is still no clinical trial with scientifically rigorous methodology to evaluate the treatment effect of TCM for tinnitus. Therefore, we propose a pilot study to inform the feasibility of a future full-scale RCT to establish the efficacy of TCM formula for tinnitus. Objectives: The aim of this study is to determine the feasibility of a full-scale RCT and explore whether a TCM formula (BHT) has an additional effect on improving tinnitus when compared to informative counseling alone. Design: An assessor-blinded, randomized, controlled clinical trial is used. Participants: Twenty-four patients with chronic subjective tinnitus will be enrolled. Interventions: The patients will be allocated randomly to receive a TCM formula (BHT, Bushen Huoxue Tongluo) and informative counseling or informative counseling alone. The oral BHT herbal granules will be taken twice per day continuously for 8 weeks. Main outcome measures: The primary outcomes include recruitment rate, intervention completion rate, and data completion rate to evaluate the feasibility. The secondary outcomes include Tinnitus Handicap Inventory, tinnitus functional index, tinnitus sensation level, self-rated visual analogue scale on tinnitus loudness and annoyance, Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale, and adverse event. The outcome measures will be collected at baseline, end of treatment, and 4-week follow-up. Discussion: This trial is currently ongoing and is recruiting patients. The expected study results will find some preliminary evidence about the clinical effectiveness of BHT on chronic tinnitus and will also determine if it is feasible to conduct a full-scale RCT of BHT and identify the necessary changes to the protocol if possible.

A novel method of bedside hyperthermic intraperitoneal chemotherapy as adjuvant therapy for stage-III gastric cancer.

OBJECTIVE: To investigate the efficacy and safety of a novel method of hyperthermic intraperitoneal chemotherapy (HIPEC) as adjuvant therapy for stage-III gastric cancer. METHODS: Patients with stage-III gastric cancer who underwent D2 radical gastrectomy were randomly assigned to the HIPEC or control group four weeks after surgery. The HIPEC group was treated with cisplatin (60 mg/m2) administered with a HIPEC device on days 1 and 3 (30 mg/m2 each time), along with oral S-1, 40-60 mg, twice daily, for 14 days. The control group was treated with cisplatin (60 mg/m2) administered intravenously plus oral S-1 (40-60 mg, 2/d for 14 days). The primary outcome of the study was disease-free survival (DFS). RESULTS: Total 114 patients were included in the study, with 57 patients in each group. The median DFS was 29.0 months in the HIPEC group, which was significantly longer than that in the control group (15.0 months, p = 0.006). The two-year DFS rate in the HIPEC group was higher than that in the control group (50.4% vs. 25.5%). Median OS was 42.0 month in the HIPEC group and 31.0 month in the control (p = 0.042). Peritoneal metastasis occurred in six patients in the HIPEC group (10.5%) and 12 patients in the control (21.1%, p = 0.198). No significant difference in the incidence of adverse event except for thrombocytopenia. CONCLUSION: HIPEC with cisplatin plus oral S-1 is a safe and effective adjuvant therapy for patients with advanced gastric cancer following D2 radical gastrectomy. Trial registration: This study was registered at ClinicalTrials.gov with the identifier (NCT number): NCT02396498.

Effect of Guo Qing Yi Tang combined with Western medicine cluster therapy on acute pancreatitis.

BACKGROUND: This study evaluated the effect of Guo Qing Yi Tang (GQYT) combined with Western medicine cluster therapy on acute pancreatitis (AP). METHODS: A total of 138 AP patients were recruited and divided into the observation group (68 patients) and control group (70 patients). The control group was treated with cluster therapy alone, while the observation group was treated with trans-jejunum feeding of GQYT combined with cluster therapy. Blood samples were taken before the treatment and 24 h, 72 h, and 1 week after the treatment. The serum concentrations of Di amine oxidase(DAO), Endotoxin(ET), D-lactic acid, Intestinal trefoil factor(ITF), MFG-E8, TNF-α, IL-1ß, IL-6, and IL-8 were determined by using spectrophotometry and enzyme-linked immunosorbent assay. The concentrations of urinary lactulose and mannitol (L/M) were determined by high-performance liquid chromatography, and the urinary L/M value was calculated. RESULTS: Compared with the control group, the observation group had shorter hospital stay, faster recovery, significantly lower APACHE II score, and higher complete response rate (94.12%) after 1 week of treatment (P < 0.05). Moreover, the indicators related to intestinal mucosal barrier function (DAO, MFG-8, L/M) and inflammatory cytokines (TNF-α, IL-6, IL-8) were significantly reduced in the observation group after 1 week of treatment (P < 0.05). CONCLUSION: GQYT combined with cluster therapy for the treatment of AP has definite curative effect and rapid onset, reduces the level of inflammatory factors, and improves intestinal mucosal barrier function and APACHE II score. Thus, it has obvious clinical therapeutic advantages and can be used as a new therapeutic regimen for AP.

Acupuncture for Poststroke Dysphagia: A Pilot, Nonrandomized, Self-Controlled Trial.

OBJECTIVE: To evaluate the effectiveness and safety of acupuncture treatment for dysphagia as a complication of stroke. Methods and Design. This is a multicenter, pragmatic, nonrandomized, self-controlled clinical trial. A total of 39 patients were recruited from several Chinese medicine outpatient clinics and hospital-affiliated speech therapy outpatient clinics in Hong Kong. 26 patients completed all the 24 sessions of acupuncture treatment within two months, and only 12 of them were used as self-control. For the self-control group, the retrospective clinical data was taken from the electronic patient records with patient consent. The descriptive swallowing function data were converted into the quantitative Royal Brisbane Hospital Outcome Measure for Swallowing (RBHOMS) scores by two registered speech therapists through a validation process. And the data were validated by reaching consensus between the two speech therapists. All subjects underwent a baseline assessment before commencement of treatment, and outcome assessments were conducted upon the completion of treatment. The primary outcome measure is the RBHOMS score, which is a swallowing disability rating scale for monitoring difficulties in daily swallowing function. Secondary outcome measures include the Chinese version of the Swallow Quality-of-Life Questionnaire and adverse events. All the primary and secondary outcomes were assessed at baseline as well as at the end of acupuncture treatment (month 2). RESULTS: A total of 39 participants aged 46 to 89 years were enrolled in the study, and the male-to-female ratio was 15 : 11. The mean baseline RBHOMS score of all 39 participants was 5.92 ± 2.23. The mean retrospective RBHOMS score of the 12 subjects who were used as self-control was 5.67 ± 1.72 before enrollment, while the mean RBHOMS score of the 26 participants who completed all the 24 sessions of treatment was 6.92 ± 2.07. There were statistically significant differences between the RBHOMS score at the completion of treatment and baseline (p=0.006), and retrospective data (p=0.042). Moreover, a significant difference was also found in terms of swallow quality-of-life score before and after acupuncture treatment (p < 0.01). CONCLUSIONS: This pilot study provides preliminary evidence for the effectiveness of acupuncture for poststroke dysphagia. The findings from this trial can be used as a foundation for future full-scale randomized controlled clinical trials to assess the efficacy and safety of acupuncture for poststroke dysphagia. Ethics and Dissemination. The ethical approval of the clinical research study was granted by the Research Ethics Committee of both New Territories East and West Cluster of Hong Kong. Written informed consent was obtained from all participants, and the study was undertaken according to the ICH-GCP Guidelines. Trial Registration. This trial is registered with ChiCTR-TRC-12002621 and the registration date is 2012-10-26.

Postoperative intraperitoneal hyperthermic perfusion improve survival for advanced gastric cancer.

To evaluate the value of intraperitoneal hyperthermic perfusion (IPHP) in the treatment of gastric cancer.Gastric cancer (GC) is a malignancy with poor prognosis, recent years have demonstrated advances in the use of IPHP for the treatment of advanced gastric cancer (AGC), but the outcome is controversial.Between January 2015 and January 2017, 134 patients with GC were treated with IPHP in our surgery department, 130 of them were advanced GC patients, and other 1439 cases were treated without IPHP for comparison. In this retrospective cohort study, demographic, perioperative data, and follow-up data were analyzed by univariant analysis, Kaplan-Meier and Cox regression survival analysis.We found the 1-year survival in IPHP group was significantly longer than it in non-IPHP group (85.5% vs 73.8%, P = .027). and IPHP decreased mortality 1.8 times in 2-year course (OR = 0.556, P = .004). The incidence rate of total complications in IPHP group was similar to that in the Non-IPHP group (6.67% vs 7.46%, respectively; P = .718). We classified all patients into four groups, operation alone, operation + chemotherapy, operation + IPHP, and operation + IPHP + chemotherapy. The 1-year survival in the groups was 70.2%, 77.5%, 83.1%, and 93.5%, respectively (P = .001), compared with the group of operation alone, the 2-year mortality risk was decreased 1.76 times (OR = 0.569, P = .030) and 2.59 times (OR = 0.385, P = .022) in operation + IPHP group and operation + IPHP + chemotherapy group.Our results suggest that IPHP could contribute to improve survival of patients with gastric cancer. And the modality of operation + IPHP + chemotherapy is the optimal treatment modality for gastric cancer.

Single herbal medicine for diabetic retinopathy.

BACKGROUND: Diabetic retinopathy is one of the major causes of blindness and the number of cases has risen in recent years. Herbal medicine has been used to treat diabetes and its complications including diabetic retinopathy for thousands of years around the world. However, common practice is not always evidence-based. Evidence is needed to help people with diabetic retinopathy or doctors to make judicious judgements about using herbal medicine as treatment. OBJECTIVES: To evaluate the effectiveness and harm of single herbal medicine for diabetic retinopathy. SEARCH METHODS: We searched CENTRAL, which contains the Cochrane Eyes and Vision Trials Register, MEDLINE, Embase, OpenGrey, the ISRCTN registry, ClinicalTrials.gov and the ICTRP. The date of the search was 12 June 2018. We also searched the following Chinese databases in June 2013: Chinese BioMedical Literature Database (CBM), Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS), Wanfang China Dissertation Database (CDDB), Wanfang China Conference Paper Database (CCPD) and the Index to Chinese Periodical Literature. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs that investigated the effects of any single herb (or extracts from a single herb) as a treatment for people with diabetic retinopathy. We considered the following comparators: placebo, no treatment, non-herbal (conventional) medicine or surgical treatment. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the risk of bias in the studies. Our prespecified outcomes were: progression of diabetic retinopathy, visual acuity, microaneurysms and haemorrhages in the retina, blood glycated haemoglobin A1c (HbA1c) (%) and adverse effects. We performed meta-analyses using risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). We assessed the certainty of the evidence using GRADE. MAIN RESULTS: We included 10 studies involving 754 participants, of which nine were conducted in China and one in Poland. In all studies, participants in both groups received conventional treatment for diabetic retinopathy which included maintaining blood glucose and lipids using medicines and keeping a stable diabetic diet. In three studies, the comparator group also received an additional potentially active comparator in the form of a vasoprotective drug. The single herbs or extracts included Ruscus extract tablet, Sanqi Tongshu capsule, tetramethylpyrazine injection, Xueshuantong injection, Puerarin injection and Xuesaitong injection. The Sanqi Tongshu capsule, Xueshuantong injection and Xuesaitong injection were all made from the extract of Radix Notoginseng (San qi) and the main ingredient was sanchinoside. The risk of bias was high in all included studies mainly due to lack of masking (blinding). None of the studies reported the primary outcome of this review, progression of retinopathy.Combined analysis of herbal interventions suggested that people who took these herbs in combination with conventional treatment may have been more likely to gain 2 or more lines of visual acuity compared to people who did not take these herbs when compared to conventional intervention alone at the end of treatment (RR 1.26, 95% CI 1.08 to 1.48; 5 trials, 541 participants; low-certainty evidence). Subgroup analyses based on the different single herbs found no evidence for different effects of different herbs, but the power of this analysis was low. One study reported Sanqi Tongshu capsule might be associated with a greater reduction in microaneurysms and haemorrhages in the retina (very low-certainty evidence). The pooled analysis of two studies on tetramethylpyrazine or Xueshuantong injection showed such herbs may have had little effect on lowering HbA1c (MD 0.00, 95% CI -0.58 to 0.58; 215 participants; low-certainty evidence).There was very low-certainty evidence on adverse events. Two studies reported minor adverse events such as uncomfortable stomach, urticaria, dizziness and headache. There was no report of observation on adverse events in the other studies. AUTHORS' CONCLUSIONS: No conclusions could be drawn about the effect of any single herb or herbal extract on diabetic retinopathy from the current available evidence. It was difficult to exclude the placebo effect as a possible explanation for observed differences due to the lack of placebo control in the included studies. Further adequately designed trials are needed to establish the evidence.

Moxibustion for alleviating side effects of chemotherapy or radiotherapy in people with cancer.

BACKGROUND: Moxibustion, a common treatment in traditional Chinese medicine, involves burning herbal preparations containing Artemisia vulgaris on or above the skin at acupuncture points. Its intended effect is to enhance body function, and it could reduce the side effects of chemotherapy or radiotherapy and improve quality of life (QoL) in people with cancer. OBJECTIVES: To assess the effects of moxibustion for alleviating side effects associated with chemotherapy, radiotherapy or both in people with cancer. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE via Ovid, Embase via Ovid and AMED (Allied and Complementary Medicine Database) from their inception to February 2018. We also searched databases in China including the Chinese BioMedical Literature Database (CBM), Chinese Medical Current Contents (CMCC), TCMonline, Chinese Dissertation Database (CDDB), China Medical Academic Conference (CMAC) and Index to Chinese Periodical Literature from inception to August 2017. Registries for clinical trials and other resources were also searched. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing moxibustion treatment, including moxa cone and moxa stick, versus sham, no treatment or conventional treatment. DATA COLLECTION AND ANALYSIS: Two review authors (HWZ and FC) independently extracted data on study design, participants, treatment and control intervention, and outcome measures, and they also assessed risk of bias in the included studies. We performed meta-analyses, expressing dichotomous outcomes as risk ratios (RR) and continuous outcomes as mean differences (MD), with 95% confidence intervals (CI). MAIN RESULTS: We included 29 RCTs involving 2569 participants. Five RCTs compared moxibustion versus no treatment, 15 compared moxibustion plus conventional treatment versus conventional treatment, one compared moxibustion versus sham moxibustion, and eight compared moxibustion versus conventional medicine. The overall risk of bias was high in 18 studies and unclear in 11 studies. Studies measured outcomes in various ways, and we could rarely pool data.Moxibustion versus no treatment: low-certainty evidence from single small studies suggested that moxibustion was associated with higher white blood cell counts (MD 1.77 × 109/L; 95% CI 0.76 to 2.78; 80 participants, low-certainty evidence) and higher serum haemoglobin concentrations (MD 1.33 g/L; 95% CI 0.59 to 2.07; 66 participants, low-certainty evidence) in people with cancer, during or after chemotherapy/radiotherapy, compared with no treatment. There was no evidence of an effect on leukopenia (RR 0.50, 95% CI 0.10 to 2.56; 72 participants, low-certainty evidence) between study groups. The effects on immune function (CD3, CD4, and CD8 counts) were inconsistent.Moxibustion versus sham moxibustion: low-certainty evidence from one study (50 participants) suggested that moxibustion improved QoL (measured as the score on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30)) compared with sham treatment (MD 14.88 points; 95% CI 4.83 to 24.93). Low-certainty evidence from this study also showed reductions in symptom scores for nausea and vomiting (MD -38.57 points, 95% CI -48.67 to -28.47) and diarrhoea (MD -13.81, 95% CI -27.52 to -0.10), and higher mean white blood cell count (MD 1.72 × 109/L, 95% CI 0.97 to 2.47), serum haemoglobin (MD 2.06 g/L, 95% CI 1.26 to 2.86) and platelets (MD 210.79 × 109/L, 95% CI 167.02 to 254.56) when compared with sham moxibustion.Moxibustion versus conventional medicines: low-certainty evidence from one study (90 participants) suggested that moxibustion improved WBC count eight days after treatment ended compared with conventional medicines (MD 0.40 × 109/L; 95% CI 0.15 to 0.65). Low-certainty evidence from two studies (235 participants) suggested moxibustion improved serum haemoglobin concentrations compared with conventional medicines (MD 10.28 g/L; 95% CI 4.51 to 16.05).Moxibustion plus conventional treatment versus conventional treatment alone: low-certainty evidence showed that moxibustion plus conventional treatment was associated with lower incidence and severity of leukopenia (WHO grade 3 to 4) (RR 0.14, 95% CI 0.01 to 2.64; 1 study, 56 participants), higher QoL scores on the EORTC QLQ-C30 (MD 8.85 points, 95% CI 4.25 to 13.46; 3 studies, 134 participants, I² = 26%), lower symptom scores for nausea and vomiting (RR 0.43, 95% CI 0.25 to 0.74; 7 studies, 801participants; I² = 19%), higher white blood cell counts (data not pooled due to heterogeneity), higher serum haemoglobin (MD 3.97 g/L, 95% CI 1.40 to 6.53; 2 studies, 142 participants, I² = 0%). There was no difference in platelet counts between the two groups (MD 13.48 × 109/L; 95% CI -16.00 to 42.95; 2 studies, 142 participants; I² = 34%).Most included studies did not report related adverse events, such as burning or allergic reactions. AUTHORS' CONCLUSIONS: Limited, low-certainty evidence suggests that moxibustion treatment may help to reduce the haematological and gastrointestinal toxicities of chemotherapy or radiotherapy, improving QoL in people with cancer; however, the evidence is not conclusive, and we cannot rule out benefits or risks with this treatment. High-quality studies that report adverse effects are needed.

Epigallocatechin gallate attenuates mitochondrial DNA-induced inflammatory damage in the development of ventilator-induced lung injury.

OBJECTIVE: We aim to investigate the role of mitochondrial DNA (mtDNA), a novel endogenous pro-inflammatory cytokine, in the development of ventilator-induced lung injury (VILI). Moreover, the protective effect of epigallocatechin gallate (EGCG) on VILI through inhibiting local mtDNA release was examined. METHODS: From March 2015 to March 2016, bronchoalveolar lavage fluid (BALF) from 36 patients with VILI and well-matched 36 patients without VILI after major surgery were consecutively collected. The expression levels of mtDNA and inflammatory cytokines in BALF were tested. SD rats were divided into five groups: control, low tidal volume (7 ml/kg) group, high tidal volume (HTV, 40 ml/kg) group, HTV+low dose EGCG and HTV+high dose EGCG groups. BALF were collected to examine the expression levels of mtDNA and several inflammatory cytokines and the lung tissue was harvested for pathological examinations. In addition, cyclic stretch cell culture was used and culture media was collected to analyze expressions of inflammatory cytokines. Administration of mtDNA in a rat model and in vitro cell culturing were used to confirm its pro-inflammatory properties in the development of inflammatory lung injury. RESULTS: A Significant elevation of mtDNA was detected in BALF from patients with VILI (581 ±â€¯193 vs. 311 ±â€¯137, p < 0.05) and also in rats ventilated with HTV. EGCG could significantly inhibit HTV-induced local mtDNA release and attenuate the level of inflammatory lung injuries (reduced infiltration of local inflammatory cells, lower lung wet/dry ratio and expression levels of inflammatory cytokines). The beneficial effects of EGCG on preventing inflammatory lung injuries were in a concentration-dependent manner. Meanwhile, higher expression levels of mtDNA and inflammatory cytokines were observed in the media of cyclic stretched cell culture compared to those in the control group (p < 0.05). Furthermore, intra-tracheal administration of mtDNA in rats could lead to a marked increase of local inflammatory cytokines and subsequent inflammatory lung injuries (p < 0.05). And by adding mtDNA into the cell culture, higher level of inflammatory cytokines in the media was detected (p < 0.05). EGCG also showed preventive effects on inflammatory responses on a concentration-dependent manner (p < 0.05). CONCLUSION: The increased expression level of mtDNA and subsequent inflammatory cytokines overproduction may play an important role in the development of VILI. EGCG may be a potential novel therapeutic candidate for protection against VILI by inhibiting the local release of mtDNA.

Effectiveness and safety of acupuncture for elderly overactive bladder population in Hong Kong: study protocol for a randomized controlled trial.

BACKGROUND: Overactive bladder (OAB) is defined as "urgency, with or without urge incontinence, usually with frequency and nocturia". Acupuncture is one of the most popular alternative treatment methods for OAB. Little established evidence is available to support the effectiveness of acupuncture for OAB. This study is a pioneer randomized, double-blinded, sham-controlled trial to assess the effectiveness and safety of acupuncture in the elderly population with overactive bladder in Hong Kong. METHODS/DESIGN: This is a randomized, double-center, patient and outcome assessor blinded, sham-controlled trial. The study sample size is 100 patients. Eligible subjects aged between 60 to 90 years old will be recruited into this study. All subjects will be randomly allocated into the active acupuncture group or sham acupuncture group in a 1: 1 ratio. Participants who are allocated into the active acupuncture group will receive a standardized 30-min real acupuncture treatment session for a total of 16 sessions on the top of standard routine care, whilst those who are randomized to the sham acupuncture arm will receive sham acupuncture in addition to standard routine care. Non-penetrating needles will be utilized as sham acupuncture. The primary outcome measure is the 7-day voiding diary and the secondary outcome measures are urine nerve growth factor (NGF) level, the Incontinence Impact Questionnaire (IIQ-7), Urogenital Distress Inventory (UDI-6) and OAB Symptom Score (OABSS). All outcome measures will be collected at baseline, the end of treatment and 3 months after treatment completion. DISCUSSION: The objectives of this study include (1) to evaluate the effectiveness and safety of acupuncture treatment in patients with OAB on reduction in the frequency of incontinence episodes as derived from a 7-day voiding diary, (2) to evaluate whether acupuncture treatment could improve subjective symptoms in patients with OAB and (3) to examine the feasibility of using NGF as a biomarker for overactive bladder and test correlation with the effectiveness of acupuncture intervention.

Effectiveness and Safety of Acupuncture for Poststroke Dysphagia: Study Protocol for a Pragmatic Multicenter Nonrandomized Controlled Trial.

Background. Dysphagia is one of the most common complications of stroke. Acupuncture is widely employed to treat poststroke dysphagia in East Asia. No evidence is established to support such treatment approach. This proposed study aims to evaluate the effectiveness and safety of acupuncture for the treatment of poststroke dysphagia. Methods and Design. This is a multicenter, pragmatic, single-blinded, nonrandomized controlled clinical trial. A total of 140 eligible patients will be enrolled in the study. Subjects who are eligible in study but refuse to have acupuncture treatment will be put on the no-acupuncture control arm. Both groups of patients will receive standard routine care, while the patients of intervention group will receive add-on standardized acupuncture treatment. Each participant in intervention group will receive a total of 24 sessions of acupuncture treatment (three times per week). The primary outcome measure is the Royal Brisbane Hospital Outcome Measure for Swallowing (RBHOMS). Secondary outcome measures include functional oral intake scale, swallow quality-of-life questionnaire in Chinese version, BMI of the participant, and adverse events. All outcome measures will be assessed at baseline, at the end of acupuncture treatment (month 2), and at two months after treatment (month 4). Ethics and Dissemination. The ethics approval of clinical research study was granted by the Research Ethics Committee of both New Territories East and West Cluster of Hong Kong. Written informed consent will be obtained from all participants and the study will be undertaken according to the ICH-GCP Guidelines. Trial Registration. This trial is registered with chictr.org (registration number: ChiCTR-TRC-12002621 and registration date: 2012-10-26).

Inhibition of acquired-resistance hepatocellular carcinoma cell growth by combining sorafenib with phosphoinositide 3-kinase and rat sarcoma inhibitor.

BACKGROUND: To provide support for combined usage of phosphoinositide 3-kinase (PI3K) inhibitors or mitogen-activated protein kinase pathway inhibitors together with sorafenib in treatment of sorafenib-resistant hepatocellular carcinoma. MATERIALS AND METHODS: The sorafenib-resistant cell lines were established to evaluate the effects of MK-2206 2HCL, a dual PI3K/mammalian target of rapamycin (mTOR) inhibitor, and PD0325901, an rat sarcoma (RAS) and/or extracellular signal-regulated kinase (ERK) inhibitor, on cell proliferation and apoptosis, as both single and combined treatments with sorafenib. In addition, multidrug resistance 1 gene expression, mutation status of key members in PI3K/mTOR, and RAS/ERK pathways and pathway activation were analyzed to identify predictors of drug response. RESULTS: Molecular studies reveal that combining MK-2206 2HCL or PD0325901 with sorafenib not only has a synergistic effect, in suppressing PI3K/protein kinase B/mTOR and RAS/MEK/ERK signaling more effectively than either treatment alone, but also prevents the cross activation of the other pathway that occurs with single treatments in both sorafenib sensitive and resistant lines. PD0325901 exhibited a stronger synergic effect with sorafenib than MK-2206 2HCL. Sorafenib-resistant cell lines were characterized by activation of both of the two pathways, as indicated by multidrug resistance 1 gene expression profiles and pathway activity analysis. CONCLUSIONS: Our studies have showed that both inhibitors of PI3K/mTOR and RAS/ERK signaling are potentially effective antihepatocellular carcinoma drugs especially in treating sorafenib-resistant hepatocellular carcinoma.

Xiaoke Pill () and anti-diabetic drugs: A review on clinical evidence of possible herb-drug interactions.

OBJECTIVE: To critically analyze the clinically-based evidence of herb-drug interaction on Xiaoke Pill () and its concomitant use with anti-diabetic drugs. METHODS: MEDLINE, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED), International Pharmaceutical Abstracts (IPA), Chinese BioMedical Literature Database (CBM), Traditional Chinese Medical Database System (TCMDS), China National Knowledge Infrastructure Database (CNKI) and Wangfang Databases were searched. Levels of Evidence and Severity Level of Interaction were used to evaluate the quality of the included studies. RESULTS: A total of 27 studies published in Chinese, including 2 randomized controlled trials, 3 case series and 22 case reports, were included. Eighteen herbdrug interactions were reported involving Xiaoke Pill as monotherapy, while 6 herb-drug interactions occurred associated with Xiaoke Pill in combination with anti-diabetic drugs. The clinical results of herb-drug interaction of Xiaoke Pill were reported as additive blood glucose-lowering effects with anti-diabetic drugs, including benefifi cial and adverse hypoglycemic effects, anaphylactic shock and severe hair loss. Of these interactions 82.8% were reported to be associated with potential deterioration of the patients' conditions including hypoglycemic coma, stroke, mental disorder and even death. CONCLUSIONS: This review helped establish the clinically-based evidence about herb-drug interaction of Xiaoke Pill and its concomitant use with anti-diabetic drugs. The fifi ndings would help arouse the awareness of both health professionals and the general public to avoid the adverse herb-drug interactions of Xiaoke Pill in healthcare and community settings.

Electroacupuncture for older adults with mild cognitive impairment: study protocol for a randomized controlled trial.

BACKGROUND: Mild cognitive impairment is an intermediary state between normal aging and clinical Alzheimer's disease. Early intervention of mild cognitive impairment may be an important strategy in the management of Alzheimer's disease. The proposal aims to evaluate if electroacupuncture would optimize cognitive function in subjects with mild cognitive impairment and understand the role of electroacupuncture in the treatment of Alzheimer's disease. METHODS/DESIGN: A randomised patient- and assessor-blind sham-controlled trial is designed to assess whether electroacupuncture intervention decreases the rate of cognitive decline amongst older adults with mild cognitive impairment. One hundred and fifty subjects aged 65 years of age or over with a diagnosis of mild cognitive impairment are recruited from the community and elderly centre in Hong Kong. All subjects are randomly allocated into two groups (75 subjects each group): the electroacupuncture group and sham control. Participants in the electroacupuncture group receive electroacupuncture stimulation by sterile, disposable acupuncture needles inserted to the acupoints with a depth of 1 to 3 cm. The acupuncture needles are subjected to 2 Hz electroacupuncture with an intensity of 5 to 10 mA. Each participant receives electroacupuncture for 8 weeks (once a day, 3 days a week) and the treatment lasts for 30 minutes each time. For sham electroacupuncture, needles are inserted to a depth of 1 to 2 mm, and connected to the electroacupuncture device without any current passing through. Outcome measures (including primary and secondary outcome measures) are collected at baseline, at the end day of intervention, and months 4 and 6 after intervention. The primary outcome is measured by the Alzheimer Disease Assessment Scale-Cognitive subscale. Secondary outcomes are measured by the mini-mental state examination, category fluency text and the Short Form 12. DISCUSSION: The study will provide evidence for evaluating and understanding the role of electroacupuncture in the treatment of Alzheimer's disease.

Tea consumption and the incidence of cancer: a systematic review and meta-analysis of prospective observational studies.

The aim of this study was to summarize the current evidence on the strength of associations between tea consumption and the incidence of cancer at different sites. We searched PubMed, Embase and the Cochrane Library for relevant articles published before October 2013. Prospective studies that reported effect estimates of cancer incidence, with 95% confidence intervals (CIs), for more than two categories of tea consumption were included. We analysed 87 datasets (57 articles), which included a total of 49,812 incident cases. Overall, high tea consumption had no significant effect on the risk of gastric, rectal, colon, lung, pancreatic, liver, breast, prostate, ovarian, bladder cancers or gliomas. However, high tea consumption was associated with a reduced risk of oral cancer (risk ratio 0.72; 95% CI 0.54-0.95; P=0.021). A dose-response meta-analysis suggested that an increase in tea consumption by one cup per day was associated with a reduced risk of oral cancer (risk ratio 0.89; 95% CI 0.80-0.98; P=0.022), but had little effect on the incidence of other cancers. Subgroup analysis indicated that an increase in the consumption of black tea by one cup per day was associated with an increased risk of breast cancer. Moreover, in western countries, we found that an increase in the consumption of tea by one cup per day was associated with a reduced risk of bladder cancer. Increased tea consumption has no significant effect on the risk of common malignancies. For some cancer types, associations differ according to sex, ethnicity and tea type.

Cordyceps sinensis (a traditional Chinese medicine) for treating chronic kidney disease.

BACKGROUND: Cordyceps sinensis (Cordyceps, Dong Chong Xia Cao), a herbal medicine also known as Chinese caterpillar fungus, is one of the most commonly used ingredients in traditional Chinese medicine for the treatment of people with chronic kidney disease (CKD). OBJECTIVES: This review aimed to evaluate the therapeutic effects and potential adverse effects of Cordyceps sinensis for the treatment of people with CKD. SEARCH METHODS: We searched the Cochrane Renal Group's Specialised Register to 14 April 2014 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. We also searched CINAHL, AMED, Current Controlled Trials, OpenSIGLE, and Chinese databases including CBM, CMCC, TCMLARS, Chinese Dissertation Database, CMAC and Index to Chinese Periodical Literature. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing Cordyceps or its products with placebo, no treatment, or conventional treatment were considered for inclusion in the review. DATA COLLECTION AND ANALYSIS: Two authors independently assessed data quality and extracted data. Statistical analyses were performed using the random-effects model and the results expressed as risk ratio (RR) for dichotomous outcomes or mean difference (MD) for continuous data with 95% confidence intervals (CI). MAIN RESULTS: We included 22 studies that involved 1746 participants. Among people with CKD who were not receiving dialysis, Cordyceps preparations were found to significantly decrease serum creatinine (14 studies, 987 participants): MD -60.76 µmol/L, 95% CI -85.82 to -35.71); increase creatinine clearance (6 studies, 362 participants): MD 9.22 mL/min, 95% CI 3.10 to 15.34) and reduce 24 hour proteinuria (4 studies, 211 participants: MD -0.15 g/24 h, 95% CI -0.24 to -0.05). However, suboptimal reporting and flawed methodological approaches meant that risk of bias was assessed as high in four studies and unclear in 18 studies, and hence, these results need to be interpreted with caution. AUTHORS' CONCLUSIONS: We found that Cordyceps preparation, as an adjuvant therapy to conventional medicine, showed potential promise to decrease serum creatinine, increase creatine clearance, reduce proteinuria and alleviate CKD-associated complications, such as increased haemoglobin and serum albumin. However, definitive conclusions could not be made because of the low quality of evidence.

Astragalus (a traditional Chinese medicine) for treating chronic kidney disease.

BACKGROUND: Astragalus (Radix Astragali, huang qi) is the dried root of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao or Astragalus membranaceus (Fisch.) Bge. (Family Leguminosae). It is one of the most widely used herbs in traditional Chinese medicine for treating kidney diseases. Evidence is needed to help clinicians and patients make judgments about its use for managing chronic kidney disease (CKD). OBJECTIVES: This review evaluated the benefits and potential harms of Astragalus for the treatment of people with CKD. SEARCH METHODS: We searched the Cochrane Renal Group's Specialised Register to 10 July 2014 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. We also searched CINAHL, AMED, Current Controlled Trials, OpenSIGLE, and Chinese databases including CBM, CMCC, TCMLARS, Chinese Dissertation Database, CMAC and Index to Chinese Periodical Literature. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs comparing Astragalus, used alone as a crude herb or an extract, with placebo, no treatment, or conventional interventions were eligible for inclusion. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed risk of bias in the included studies. Meta-analyses were performed using relative risk (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). MAIN RESULTS: We included 22 studies that involved 1323 participants, of whom 241 were receiving dialysis treatment. Risk of bias was assessed as high in six studies, and unclear in the remaining 16 studies. Study quality was low overall.Our nominated primary outcomes of time to requirement for renal replacement therapy (RRT) or initiation of dialysis and all-cause mortality were not reported in any of the included studies.Results concerning the effects of Astragalus on kidney function were inconsistent. Astragalus significantly increased CrCl at end of treatment (4 studies, 306 participants: MD 5.75 mL/min, 95% CI 3.16 to 8.34; I² = 0%), decreased SCr (13 studies, 775 participants: MD -21.39 µmol/L, 95% CI -34.78 to -8; I² = 70%) and especially in those whose baseline SCr was < 133 µmol/L in particular (3 studies, 187 participants: MD -2.52 µmol/l, 95% CI -8.47 to 3.42; I² = 0%). Astragalus significantly decreased 24 hour proteinuria at end of treatment (10 studies, 640 participants; MD -0.53 g/24 h, 95% CI -0.79 to -0.26; I² = 90%); significantly increased haemoglobin levels overall (4 studies, 222 participants): MD 9.51 g/L, 95% CI 4.90 to 14.11; I² = 0%) and in haemodialysis patients in particular (3 studies, 142 participants: MD 11.20 g/L, 95% CI 5.81 to 16.59; I² = 0%). Astragalus significantly increased serum albumin (9 studies, 522 participants: MD 3.55 g/L, 95% CI 2.33 to 4.78; I² = 65%). This significant increase was seen in both dialysis (3 studies, 152 participants): MD 4.04 g/L, 95% CI 1.91 to 6.16; I² = 72%) and non-dialysis patients (6 studies, 370 participants: MD 3.24 g/L, 95% CI 1.70 to 4.77; I² = 61%). Astragalus significantly decreased systolic blood pressure (2 studies, 77 participants: MD -16.65 mm Hg, 95% CI -28.83 to -4.47; I² = 50%), and diastolic blood pressure (2 studies, 77 participants: MD -6.02 mm Hg, 95% CI -10.59 to -1.46; I² = 0%).Six of 22 included studies reported no adverse effects were observed; while the remaining 16 studies did not report adverse effects. AUTHORS' CONCLUSIONS: Although Astragalus as an adjunctive treatment to conventional therapies was found to offer some promising effects in reducing proteinuria and increasing haemoglobin and serum albumin, suboptimal methodological quality and poor reporting meant that definitive conclusions could not be made based on available evidence.
