Emesis in patients receiving acupuncture,sham acupuncture or standard care during chemo-radiation: A randomized controlled study

ObjectiveTo study nausea, vomiting and need for rescue antiemetics in patients receiving antiemetic acupuncture, sham acupuncture or standard care during concomitant chemotherapy during pelvic radiotherapy.MethodsIn total, 68 patients participated (75% women, mean age 56 years, 53% had gynecological, 43% colorectal, and 4% other cancer types). Fifty-seven of them were blinded randomized to verum (n = 28) or sham (n = 29) acupuncture, median 10 sessions. During the study period of four weeks, the patients daily registered their nausea, vomiting and consumption of antiemetics. They were compared to a reference group (n = 11) receiving standard care only, who delivered these data once (after receiving mean 27 Gy radiotherapy dose).ResultsMore patients in the sham acupuncture group (17 of 20; 85%, p = 0.019, RR 1.81, CI 1.06–3.09) consumed antiemetics, compared to the verum acupuncture group (8 of 17; 47%). In the standard care group, 7 of 11 (63%) consumed antiemetics. The verum acupuncture treated patients experienced lower intensity of nausea than the other patients (p = 0.049). There was a non-significant tendency that more patients receiving either sham acupuncture or standard care experienced nausea (21 of 31; 68%) than patients receiving verum acupuncture (9 of 17; 53%: p = 0.074, RR 1.58, CI 0.91–2.74).ConclusionPatients treated with verum acupuncture needed less antiemetics and experienced milder nausea than other patients. Our study was small and many analyses lacked statistical power to detect differences; we welcome further sham-controlled efficacy studies and studies regarding the role of non-specific treatment components for experiencing antiemetic effects of acupuncture.     

Exercises improve body composition,cardiovascular risk factors and bone mineral density for menopausal women: A systematic review and meta-analysis of randomized controlled trials

BackgroundMenopause has been considered as an aggravating factor for developing cardiovascular diseases and the metabolic syndromes for women. Exercise might be an effective intervention for reducing such threats.ObjectiveThe purpose of this study was to evaluate the exercise effects on body composition, cardiovascular risk factors, and bone mineral density of menopausal women.MethodsTwo reviewers did a complete search of five electronic database (Medline, PubMed, Cochrane Central Register of Controlled Trials, CINAHL, and the Chinese Electronic Periodical Service) records up to January 31, 2014. Randomized controlled trials (RCTs) that compared female menopausal participants with exercises, and those without exercise or with placebo were included. Risk of bias was classified based on the Cochrane Collaboration tool, the meta-analysis was conducted using Comprehensive Meta-Analysis Version 2.2. The study selection, data extraction, and validation were performed independently by the 2 reviewers.ResultsA total of 17 RCTs with 792 participants were included for meta-analysis. Among the eight RCTs (247 participants), a moderate effect size of exercise on body fat was found (SMD = − 0.34, 95% CI: − 0.60 to − 0.08). In five RCTs (195 participants), a moderate effect size of exercise on waist circumference (SMD = − 0.39, 95% CI: − 0.68 to − 0.09), in seven RCTs (162 participants), a moderate effect size on triglyceride level (SMD = − 0.37, 95% CI: − 0.62 to − 0.11), and in five RCTs (311 participants), a moderate effect size on bone mineral density (SMD = 0.38, 95% CI: 0.08–0.68). Subgroup analysis revealed a significant effect of aerobic exercise on body fat (SMD = − 0.29, 95% CI: − 0.53 to − 0.06), and a short-term exercise on body fat (SMD = − 0.50, 95% CI: − 0.89 to − 0.11) and on triglycerides (SMD = − 0.42, 95% CI: − 0.79 to − 0.04). The trials included in this meta-analysis were small and some had methodologic limitations.ConclusionsThis study provides evidences to clinical practice for menopause women that exercise, compared with nonexercise or placebo exerted significant benefits on body fat, waist circumference, triglyceride level, and lumbar spine bone mineral density. Particularly, aerobic exercise did help menopausal women improve their body fat. A short-term exercise intervention had a benefit on not only body fat but also triglyceride level. However, well-designed, well-executed RCTs, and a detailed long-term clinical research should be needed in the future.     

Involvement of serotonin in the hypoglycemic response to 2 Hz electroacupuncture of zusanli acupoint (ST36) in rats

In our previous studies, an insulin-dependent hypoglycemic effect produced by electroacupuncture (EA) was shown to be mediated by endogenous opioid peptides (EOP). In the present study, we applied 2 Hz EA to both zusanli acupoints (ST36) in the test group for 30 min, and to a nonacupoint area in the control group for 30 min to compare the acupoint specific character in the hypoglycemic effect of EA. Assays of plasma beta-endorphin and insulin levels were performed by ELISA kits. The insulin-dependent mechanism of the hypoglycemic effect was also investigated in streptozotocin (STZ)-induced diabetic rats. The mediation of EOP and the role of mu-opioid receptor were examined by naloxone and mu-opioid receptor knockout mice (MOR-KOM). The serotonin depletion was carried out by injecting (i.p.) p-chlorophenylalanine (PCPA); two low doses of serotonin were also injected (i.v.) to analyze the direct effect on plasma glucose levels. The hypoglycemic effect of EA was much greater in rats stimulated at ST36 than in rats receiving the same stimulation at the nonacupoint area. The plasma levels of insulin and beta-endorphin were also significantly elevated after stimulation of both zusanli acupoints, but remained unchanged following stimulation at the nonacupoint area. There was no sharp hypoglycemic response to 2 Hz EA at zusanli acupoint of STZ-induced diabetic rats. However, the hypoglycemic effect of this EA was not totally blocked by the sufficient dose of naloxone (1 mg/kg, i.v.). Additionally, 2 Hz EA at ST36 also showed a sharp decrease in plasma glucose levels of MOR-KOM. Pretreatment with PCPA did not reproduce hypoglycemic response to 2 Hz EA in naloxone-treated rats and MOR-KOM mice. Furthermore, injection of serotonin decreased the plasma glucose levels significantly. Therefore, we suggest that serotonin also involved in the hypoglycemic action of 2 Hz EA at both zusanli acupoints of normal rats.     

Effects of thermal therapy on uremic pruritus and biochemical parameters in patients having haemodialysis

Title.  Effects of thermal therapy on uremic pruritus and biochemical parameters in patients having haemodialysis.
Aim.  This paper is a report of a trial to identify the effect of thermal therapy with far-infrared rays in comparison with non-thermal therapy on uremic pruritus and biochemical parameters.
Background.  Uremic pruritus remains one of the most frustrating, common, and potentially disabling symptoms in patients undergoing haemodialysis. The mechanism underlying uremic pruritus is poorly understood. Although enough is known to determine a reasonable treatment approach, more research is needed to evaluate more reliable treatments.
Methods.  A randomized, double-blind, controlled trial was conducted in 2005 using questionnaires and measurement of blood biochemical parameters. A total of 41 uremic patients on maintenance haemodialysis were randomly assigned either to the thermal therapy group or the control group. The thermal therapy group was treated with 40°C thermal therapy with far-infrared rays at the Sanyinjiao acupoint for 15 minutes once a day on two days a week for a total of 18 sessions. The control group received a plain adhesive patch placed on the same acupoint.
Findings.  Both groups showed statistically significant improvements but there were no differences between groups, while a relatively large decrease in pruritus scores was found in the thermal therapy group ( P  < 0·001) as compared with the non-thermal therapy group. Serum calcium level decreased statistically significantly in the thermal therapy group and was statistically significantly different from that of the control group.
Conclusion.  The lack of effect does not necessarily demonstrate that thermal therapy is not effective or has no therapeutic benefits for uremic pruritus in patients having haemodialysis. Further investigation is warranted, with larger samples and longer intervention.     

Angiocentric glioma: A case report and review of the literature

BackgroundAngiocentric glioma (AG) is a rare, low-grade glioma with slow growth. In 2007, AG was first classified as a solid tumor according to the WHO classification of the central nervous system (WHO class I). The outcome and prognosis of most of the cases are very good, but a few cases with tumor metastasis and disease progression, even death, have been reported. We report a case and systematically analyze previous literature to increase our understanding of the disease and determine the factors that may affect disease progression to make prognostic judgments.Case presentationA young male patient complained of a 3-year history of epilepsy. Anti-epileptic drug treatment was ineffective. An imaging examination revealed a lesion in the left parietal cortex area. Thus, the lesion was completely resected. The pathological diagnosis was angiocentric glioma. During a follow-up of two years, the patient had epilepsy relief controlled by sodium valproate and a disease-free period.ConclusionAG is an epilepsy-related low-grade glioma that heals after complete resection in most reported cases. However, few reported cases have had disease progression and death. This result may be due to the pathological complexity of the diseased tissue. In addition, AG is usually found to have an MYB–QKI rearrangement on genetic analysis. Due to the small number of reported cases and studies, our understanding and knowledge of this disease are still lacking. The potential malignant changes and prognostic factors need to be verified in more than clinical cases and basic research in the future.     

Risks and benefits of timely screw removal after thoracolumbar spine fractures treated with non-fusion technique

BackgroundPercutaneous-short segment screw fixation (SSSF) without bone fusion has proven to be a safe and effective modality for thoracolumbar spine fractures (TLSFs). When fracture consolidation is confirmed, pedicle screws are no longer essential, but clear indications for screw removal following fracture consolidation have not been established.MethodsIn total, we enrolled 31 patients with TLSFs who underwent screw removal following treatment using percutaneous-SSSF without fusion. Plain radiographs, taken at different intervals, measured local kyphosis using Cobb’ angle (CA), vertebra body height (VBH), and the segmental motion angle (SMA). A visual analogue scale (VAS) and the Oswestry disability index (ODI) were applied pre-screw removal and at the last follow-up.ResultsThe overall mean CA deteriorated by 1.58° (p < 0.05) and the overall mean VBH decreased by 0.52 mm (p = 0.001). SMA preservation was achieved in 18 patients (58.1%) and kyphotic recurrence occurred in 4 patients (12.9%). SMA preservation was statistically significant in patients who underwent screw removal within 12 months following the primary operation (p = 0.002). Kyphotic recurrence occurred in patients with a CA ≥ 20° at injury (p < 0.001) with a median interval of 16.5 months after screw removal. No patients reported worsening pain or an increased ODI score after screw removal.ConclusionScrew removal within 12 months can be recommended for restoration of SMA with improvement in clinical outcomes. Although, TLSFs with CA ≥ 20° at the time of injury can help to predict kyphotic recurrence after screw removal, the clinical outcomes are less relevant.     

Triptolide induced cell death through apoptosis and autophagy in murine leukemia WEHI‐3 cells in vitro and promoting immune responses in WEHI‐3 generated leukemia mice in vivo

Triptolide, a traditional Chinese medicine, obtained from Tripterygium wilfordii Hook F, has anti‐inflammatory, antiproliferative, and proapoptotic properties. We investigated the potential efficacy of triptolide on murine leukemia by measuring the triptolide‐induced cytotoxicity in murine leukemia WEHI‐3 cells in vitro. Results indicated that triptolide induced cell morphological changes and induced cytotoxic effects through G0/G1 phase arrest, induction of apoptosis. Flow cytometric assays showed that triptolide increased the production of reactive oxygen species, Ca²⁺ release and mitochondrial membrane potential (ΔΨ_m), and activations of caspase‐8, ‐9, and ‐3. Triptolide increased protein levels of Fas, Fas‐L, Bax, cytochrome c, caspase‐9, Endo G, Apaf‐1, PARP, caspase‐3 but reduced levels of AIF, ATF6α, ATF6β, and GRP78 in WEHI‐3 cells. Triptolide stimulated autophagy based on an increase in acidic vacuoles, monodansylcadaverine staining for LC‐3 expression and increased protein levels of ATG 5, ATG 7, and ATG 12. The in vitro data suggest that the cytotoxic effects of triptolide may involve cross‐talk between cross‐interaction of apoptosis and autophagy. Normal BALB/c mice were i.p. injected with WEHI‐3 cells to generate leukemia and were oral treatment with triptolide at 0, 0.02, and 0.2 mg/kg for 3 weeks then animals were weighted and blood, liver, spleen samples were collected. Results indicated that triptolide did not significantly affect the weights of animal body, spleen and liver of leukemia mice, however, triptolide significant increased the cell populations of T cells (CD3), B cells (CD19), monocytes (CD11b), and macrophage (Mac‐3). Furthermore, triptolide increased the phagocytosis of macrophage from peripheral blood mononuclear cells (PBMC) but not effects from peritoneum. Triptolide promoted T and B cell proliferation at 0.02 and 0.2 mg/kg treatment when cells were pretreated with Con A and LPS stimulation, respectively; however, triptolide did not significant affect NK cell activities in vivo. © 2016 Wiley Periodicals, Inc.

Effectiveness of Yoga Interventions in Breast Cancer-Related lymphedema: A systematic review

ObjectivesTo synthesize recent empirical evidence on yoga-based interventions for patients with breast cancer-related lymphedema.MethodsWe searched the PubMed/MEDLINE, Cochrane Central Register of Controlled Trials and EMBASE databases for studies published between October 2007 and September 2018 in any language. Risk of bias and methodological quality were evaluated using the PRISMA statement and checklist and the Cochrane Collaboration tool.ResultsThere was significant improvement in lymphedema status, range of shoulder motion and spinal mobility after an 8-week yoga intervention, whereas there was no consistency in quality of life following yoga intervention. Additionally, there was no difference in lymphedema status, extracellular fluid and tissue resistance outcomes in the affected arm following a long-term yoga practice.ConclusionThe current findings could not be clearly demonstrated that yoga programme intervention as an addition to usual care is superior to along usual care, and keep yoga exercise does not provide significant added benefits.
