RESUMO

Background: With the development of positive psychology, posttraumatic growth research on cancer patients has attracted increasing attention from researchers. It is immensely important to effectively increase the posttraumatic growth level of cancer patients and improve their quality of life. Objectives: To investigate the effectiveness of a nurse-led mindfulness-based Tai Chi Chuan (MTCC) programme for increasing posttraumatic growth (PTG) and decreasing the perceived stress and anxiety of breast cancer survivors. Methods: A RCT was conducted. Participants were randomly assigned to either the MTCC group or the control group. The programme included 59 women with stage I-III breast cancer. Participants in the intervention group participated in a nurse-led 8-week, twice a week, one-hour per day mindfulness-based exercise programme. The effectiveness of the intervention was measured three times (T1 - before intervention; T2 - after intervention; T3 - one year after intervention) using validated scales, including the PTG inventory (PTGI), Perceived Stress Scale (PSS), and Self-rating Anxiety Scale (SAS). A repeated-measure analysis of variance model was used to analyse the data. Results: Compared with the wait-list control group, the PTG level in the MTCC group was much higher after the 8-week intervention and the follow-up (F = 374.98, P < .000). The results showed that MTCC increased the level of PTG, and the effect persisted 1 year after intervention. In addition, PSS (F = 55.22, P < .000) and SAS (F = 148.92, P < .000) scores were significantly decreased at T2 and T3. Conclusion: The research preliminarily revealed that the MTCC programme was simple, effective, and more suitable to clinical nurses which should be recommended to cancer survivors to promote their recovery.


Antecedentes: Con el desarrollo de la psicología positiva, la investigación de crecimiento postraumático en pacientes con cáncer ha atraído cada vez más la atención de los investigadores. Es sumamente importante aumentar de manera eficaz el nivel de crecimiento postraumático de los pacientes con cáncer y mejorar su calidad de vida.Objetivos: Investigar la efectividad de un programa de Tai Chi Chuan basado en mindfulness (MTCC en sus siglas en inglés) dirigido por enfermeras para aumentar el crecimiento postraumático (PTG en sus siglas en inglés) y disminuir la percepción de estrés y ansiedad de las sobrevivientes de cáncer de mama.Métodos: Se condujo un ECA. Las participantes fueron asignadas al azar al grupo MTCC o al grupo control. El programa incluyó a cincuenta y nueve mujeres con cáncer de mama en estadio I-III. Las participantes en el grupo de intervención participaron en un programa de ejercicios basados en mindfulness dirigido por enfermeras, de 8 semanas, dos veces por semana, de una hora diaria. La efectividad de la intervención se midió tres veces (T1 ­ antes de la intervención; T2 ­ después de la intervención; T3 ­ un año después de la intervención) usando escalas validadas, incluidas el inventario de PTG (PTGI), la Escala de Estrés Percibida (PSS) y la Escala de Ansiedad Auto-reportada (SAS). Para analizar los datos se utilizó un modelo de análisis de varianza de medidas repetidas.Resultados: En comparación con el grupo control de la lista de espera, el nivel de PTG en el grupo MTCC fue mucho más alto después de intervención de 8 semanas y al seguimiento (F = 374.98, P< 0.000). Los resultados mostraron que la MTCC aumentó los niveles de PTG y el efecto persistió un año después de la intervención. Además, las puntuaciones de PSS (F = 55.22, P< 0.000) y SAS (F = 148.92, P< 0.000) disminuyeron significativamente en T2 y T3.Conclusiones: Las investigaciones preliminares revelaron que el programa de MTCC era simple, efectivo y más adecuado para las enfermeras clínicas, lo que debería recomendarse a las sobrevivientes de cáncer para promover su recuperación.

RESUMO

OBJECTIVE: To investigate the effects and possible mechanisms of action of Curcuma wenyujin Y. H. Chen et C. Ling n-Butyl alcohol extract (CWNAE) on repression of human gastric cancer (GC) AGS cell invasion induced by co-culturing with Helicobacter pylori (HP). METHODS: AGS cells were cultured with HP of positive or negative cytotoxin-associated gene A (CagA) and vacuolating cytotoxin gene A (VacA) expression (CagA+/- or VacA+/-) and divided into 5 group. Group A was cultured without HP as a control, Group B with HPCagA+VacA+, Group C with HPCagA-VacA-, Group D with HPCagA+VacA+ and CWNAE, and Group E with HPCagA-VacA- and CWNAE. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) and tumor invasion assays, examinations of morphology and ultramicroscopic structures, quantitative real-time polymerase chain reaction and Western blots were performed to measure the effects and uncover the mechanisms behind these effects of HPCagA+VacA+ and CWNAE on the epithelial-mesenchymal transition (EMT) of AGS cells. RESULTS: The 10% inhibitory concentration of CWNAE against AGS cells after a 48 h incubation was 19.73±1.30 µg/mL. More AGS cells were elongated after co-culturing with HPCagA+VacA+ than after culturing with HPCagA-VacA-. In tumor invasion assays, HPCagA+VacA+ significantly enhanced the invasiveness of AGS cells compared to the other experimental groups (all P value <0.05), and this effect was inhibited by CWNAE. Treatment with CWNAE normalized tight junctions and reduced the number of pseudopodia of AGS cells co-cultured with HPCagA+VacA+. HPCagA+VacA+ up-regulated zincfinger ebox binding homeobox 1 (ZEB1) in AGS cells after co-culturing for 24 h. Expression of caudal type homeobox transcription factor (CDX-2) and claudin-2 was significantly increased by HPCagA+VacA+ (P<0.05), but not by HPCagA-VacA-. CONCLUSION: HPCagA+VacA+ promoted the invasiveness of AGS cells through up-regulation of ZEB1 transcription and claudin-2 and CDX-2 expression. CWNAE inhibited these effects of HPCagA+VacA+ on AGS cells by down-regulating ZEB1 transcription, and CDX-2 and claudin-2 expression.

RESUMO

BACKGROUND: Sub-threshold depression (SD) has been associated with impairments in adolescent health which increase the rate of major depression. Researchers have shown the effectiveness of mindfulness on mental health, however whether the traditional mindful skills were suitable for youngsters, it was not clear. This study investigated the effects of a tailed Mindfulness-based stress reduction (MBSR) on their psychological state. METHODS: A double-blind, randomized controlled trial was carried out. 56 participants who met the inclusion criteria agreed to be arranged randomly to either the MBSR group (n=28) or the control group (n=28). Participants in MBSR group received a tailored 8-week, one time per week, one hour each time group intervention. The effectiveness of intervention was measured using validated scales, which including BDI-II, MAAS, RRS at three times (T1-before intervention; T2-after intervention; T3-three months after intervention). A repeated-measures analysis of variance model was used to analyze the data. RESULTS: The results showed significant improvements in MBSR group comparing with control group that depression level decreased after the 8-week intervention and the follow up (F =17.721, p < 0.00). At the same time, RRS score was significantly decreased at T2 and T3(F= 28.277, p < 0.00). The results also showed that MBSR promoted the level of mindfulness and the effect persisted for three months after intervention (F=13.489, p < 0.00). CONCLUSION: A tailored MBSR intervention has positive effects on psychology health among SD youngsters, including decrease depression and rumination level, cultivate mindfulness.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) decoction Chang'an I Recipe ( I ) in the treatment of irritable bowel syndrome with diarrhea (IBS-D). METHOD: A multicenter, randomized, double-blind, placebo-controlled clinical trial was designed. Based on the order of inclusion, the IBS-D patients were randomly assigned to the treatment group or the placebo control group, administrated with Chang'an I Recipe or placebo, 150 mL/bag, 3 times daily, for 8 weeks. The primary indices of efficacy included the effective rates of IBS symptom severity score (IBS-SSS) and the differences in adequate relief (AR) responder; the secondary indexes of efficacy included the changes in scores of the IBS Quality of Life (IBS-QOL) and Hospital Anxiety and Depression (HAD) scales. The safety indices included adverse events and related laboratory tests. RESULTS: A total of 216 patients were included, with 109 in the treatment group and 107 in the control group, and finally 206 were included in the full analysis set (FAS), 191 were included in the per protocol set (PPS). In FAS, the total effective rate was 67.6% and 40.2% for the treatment and control groups, respectively, with 95% confidence interval (CI) for difference in the effective rates between the two groups of 14.4%-40.2%; while in PPS, the total effective rate was 71.3% and 41.2% for the treatment and control groups, respectively (95% CI 16.6%-43.4%). The consistent conclusions of FAS and PPS showed a better efficacy in the treatment group. Both FAS and PPS showed higher AR responder in the treatment group (FAS: 59.6% vs. 35.5%; PPS: 62.8% vs. 38.1%). As for IBS-QOL, the total score and scores in various dimensions of IBS-QOL were not significantly different between the two groups (P>0.05). Both anxiety and depression scales of HAD were not significantly different between the two groups (P>0.05). No adverse events or laboratory abnormalities were found to be obviously related to the tested drugs or clinically significant. CONCLUSION: Chang'an I Recipe was more effective than placebo in the treatment of IBS-D, with no obvious adverse reactions. (No.ChiCTR-TRC-09000328).

RESUMO

Objective. To investigate effects and possible mechanisms of transcutaneous electrical acustimulation (TEA) performed by a wearable watch-size stimulator for refractory gastroesophageal reflux disease (RGERD). Methods. Twenty patients diagnosed as RGERD were enrolled in the study and randomly divided into four groups: esomeprazole group (Group A), esomeprazole combined with TEA group (Group B), esomeprazole combined with sham-TEA group (Group C), and esomeprazole combined with domperidone group (Group D). HRM and 24 h pH-impedance monitoring and GerdQ score were used to measure related indexes before and after treatment. Results. (1) TEA significantly increased LESP, compared with PPI treatment only or PPI plus sham-TEA. After pairwise comparison, LESP of Group B was increased more than Group A (P = 0.008) or Group C (P = 0.021). (2) PPI plus TEA decreased not only the number of acid reflux episodes but also the number of weak acid reflux episodes (P = 0.005). (3) Heartburn and reflux symptoms were improved more with PPI + TEA than with PPI treatment only or PPI plus sham-TEA (GerdQ scores, P = 0.001). Conclusion. TEA can improve symptoms in RGERD patients by increasing LESP and decreasing events of weak acid reflux and acid reflux; addition of TEA to esomeprazole significantly enhances the effect of TEA.

RESUMO

Tongguan Liqiao acupuncture therapy has been shown to effectively treat dysphagia after stroke-based pseudobulbar paralysis. We presumed that this therapy would be effective for dysphagia after bulbar paralysis in patients with brainstem infarction. Sixty-four patients with dysphagia following brainstem infarction were recruited and divided into a medulla oblongata infarction group (n = 22), a midbrain and pons infarction group (n = 16), and a multiple cerebral infarction group (n = 26) according to their magnetic resonance imaging results. All patients received Tongguan Liqiao acupuncture for 28 days. The main acupoints were Neiguan (PC6), Renzhong (DU26), Sanyinjiao (SP6), Fengchi (GB20), Wangu (GB12), and Yifeng (SJ17). Furthermore, the posterior pharyngeal wall was pricked. Before and after treatment, patient swallowing functions were evaluated with the Kubota Water Test, Fujishima Ichiro Rating Scale, and the Standard Swallowing Assessment. The Barthel Index was also used to evaluate their quality of life. Results showed that after 28 days of treatment, scores on the Kubota Water Test and Standard Swallowing Assessment had decreased, but scores on the Fujishima Ichiro Rating Scale and Barthel Index had increased in each group. The total efficacy rate was 92.2% after treatment, and was most obvious in patients with medulla oblongata infarction (95.9%). These findings suggest that Tongguan Liqiao acupuncture therapy can repair the connection of upper motor neurons to the medulla oblongata motor nucleus, promote the recovery of brainstem infarction, and improve patient's swallowing ability and quality of life.

RESUMO

Nausea and vomiting are one of the major complications of chemotherapy for cancers. The aim of this study is to investigate the emetic effects and mechanisms involving serotonin and dopamine of needleless transcutaneous electroacupuncture (TEA) at Neiguan (PC6) and Jianshi (PC5) on chemotherapy-induced nausea and vomiting in patients with cancers. Seventy-two patients with chemotherapy were randomly divided into sham-TEA group (sham-TEA, n = 34) and TEA group (n = 38). TEA was performed at PC 6 and PC 5 (1 h, bid) in combination with granisetron. Sham-TEA was delivered at nonacupoints using the same parameters. We found the following. (1) In the acute phase, the conventional antiemetic therapy using Ondansetron effectively reduced nausea and vomiting; the addition of TEA did not show any additive effects. In the delayed phase, however, TEA significantly increased the rate of complete control (P < 0.01) and reduced the nausea score (P < 0.05), compared with sham-TEA. (2) TEA significantly reduced serum levels of 5-HT and dopamine in comparison with sham-TEA. Those results demonstrate that needleless transcutaneous electroacupuncture at PC6 using a watch-size digital stimulator improves emesis and reduces nausea in the delayed phase of chemotherapy in patients with cancers. This antiemetic effect is possibly mediated via mechanisms involving serotonin and dopamine.

RESUMO

OBJECTIVE: To study the effect of Weifuchun on inflammation of Helicobacter pylori (Hp)-infected gastric epithelial cells (GES-1) and its correlation with NF-kappaB signaling pathway. METHODS: Hp standard home-made strain (CagA +, VacA +) NCTCI 1637 infected GES-1 cells were used. Weifuchun was used as intervention. Weifuchun of different concentrations (5,10, and 20 microg/mL) were screened by MTT assay. A blank group and the model group were set up. Then the growth inhibition rate of drugs on gastric epithelial GES-1 cells was detected with MTT assay. Cell cycle was detected using flow cytometry. The supernatant liquid was separated to detect the contents of IL-8 and IL-4 by ELISA.The protein expression level of NF-kappaB was detected by Western blot analysis. RESULTS: MTT assay indicated significantly inhibitory effect of Weifuchun on GES-1 cells [5% inhibiting concentration (IC5)] was 10 microg/ml in the Weifuchun group. After GES-1 and Hp were cultured together,the contents of IL-8 in the supernatant were more obviously higher in the model group than in the blank group (P < 0.05), and then gradually decreased. After treatment with different concentrations of Weifuchun, the levels of IL-8 in the supernatant were less when compared with the model group at 12, 24, 48, and 72 h (P < 0.05). The decrement was the most significant in the high dose Weifuchun group. The IL-4 level in the supernatant was obviously lower in the model group than in the blank group. It obviously increased in the high concentration Weifuchun group (P < 0.05). There was no statistical difference in the IL-4 level between middle, low concentration Weifuchun group and the blank group (P > 0.05). The protein expression of intranuclear P65 increased and that of IkBalpha decreased 60 min after Hp infection. But the protein expression of intranuclear P65 decreased and the protein expression of IkBalpha increased after intervention of Weifuchun. CONCLUSIONS: Weifuchun adjusted H. pylori induced IL-8 and IL-4 production by gastric epithelial cells through blocking NF-kappaB pathways. Its mechanisms might possibly lie in inhibiting p65 from entry into nucleus and the degradation of IkBalpha. Weifuchun was an effective drug for treatment of Hp correlated chronic gastritis.

RESUMO

OBJECTIVE: To explore the reversal effect of multidrug resistance of Curcuma Wenyujin (CW) and its possible mechanism by establishing Vincristine-resistant gastric cancer SGC-7901 cells (SGC-7901/VCR) induced subcutaneous transplanted tumor in nude mice. METHODS: First we identified the resistance of SGC-7901/VCR by using methyl thiazolyl tetrazolium (MTT). The SGC-7901/VCR induced subcutaneous transplanted tumor model was established in 50 BALB/c nude mice by tissue block method. After 2 -3 weeks 36 mice with similar tumor size were selected and divided into 6 groups by random digit table, i.e., the model group, the Vincristine (VCR) group, the low dose CW group, the high dose CW group, the low dose CW combined VCR group, and the high dose CW combined VCR group, 6 in each group. Normal saline was intraperitoneally injected to mice in the model group at 10 mL/kg, once per 2 days. VCR was intraperitoneally injected to mice in the VCR group at 0.28 mg/kg once per 2 days. CW at 1.4 and 2.8 g/kg was administered to mice in the low and high dose CW groups by gastrogavage, 0.2 mL each time, once daily. CW at 1.4 and 2.8 g/kg was administered by gastrogavage and VCR was intraperitoneally injected at 0.28 mg/kg, once per 2 days to mice in the low dose CW combined VCR group and the high dose CW combined VCR group. All medication lasted for 14 days. The tumor growth was observed. The inhibition rate was calculated. Meanwhile, the positioning and expression of P-glycoprotein (P-gp) were detected by immunohistochemistry and Western blot. RESULTS: SGC-7901/VCR had strong resistance to VCR, Adramycin (ADM), fluorouracil (5-FU), and Cisplatin (DDP), especially to VCR. Proliferation activities of SGC-7901/VCR were significantly enhanced after drug elution. The tumor volume gradually increased as time went by. The tumor volume was the minimum in the high dose CW combined VCR group. The tumor volume was obviously reduced in the high dose CW combined VCR group with obviously reduced with increased inhibition rate of 51.56%, when compared with that of the model group and the VCR group (P < 0.05). Western blot test showed that, when compared with the model group, the gray level of P-gp in the VCR group increased (P < 0.05), and the relative expression of P-gp in the high dose CW group, the low dose CW combined VCR group, and the high dose CW combined VCR group significantly decreased (P < 0.05). Compared with the VCR group, the gray level of the P-gp decreased in the low dose CW group, the high dose CW group, the low dose CW combined VCR group, and the high dose CW combined VCR group (P < 0.05). Results of immunohistochemistry showed that, when compared with the model group, expression scores of P-gp in the high dose CW group, the low dose CW combined VCR group, and the high dose CW combined VCR group decreased with statistical difference (P < 0.05). Compared with the VCR group, expression scores of P-gp were obviously lowered in the low dose CW group, the high dose CW group, the low dose CW combined VCR group, and the high dose CW combined VCR group (P < 0.05). CONCLUSIONS: CW could reverse the drug resistance of SGC-7901/VCR subcutaneous transplanted tumor. And its mechanism might be related to down-regulating the expression of P-gp, suggesting that CW could be used as a kind of multidrug resistance reversal agent based on P-gp.

RESUMO

AIM: To study effect of diterpenoid C extracted from radix curcumae on Helicobacter pylori (H. pylori)-infected inflammation, intestinal metaplasia, and nuclear factor kappa B (NF-κB) signaling pathway in vitro. METHODS: We used I-type H. pylori to infect human gastric epithelial gastric epithelium cell line (GES-1) cell lines, and then H. pylori-infected GES-1 cells were treated with radix curcumae (RC)-derived diterpenoid C of different concentrations (5, 10, 20 µg/mL) and amoxicillin. The expression of p65, IκB kinase (IKK) α and IKKγ proteins was detected with Western blotting, and the expression of interleukin (IL)-8, IL-6 and IL-4 was determined with enzyme-linked immunosorbent assay method. Data were analyzed using SPSS software ver18.0. For comparisons between groups of more than two unpaired values, one-way analysis of variance (ANOVA) was used. If an ANOVA F value was significant, post hoc comparisons were performed between groups. If results were not normally distributed, the Mann-Whitney U test was used to compare two groups of unpaired values, whereas for comparisons between groups of more than two unpaired values, the Kruskal-Wallis H test was used. Statistical significance was established at P < 0.05. RESULTS: The MTT assay results revealed the inhibited rate of GES-1, and indicated that the IC5 of RC-derived diterpenoid C and amoxicillin all were 5 µg/mL for gastric GES-1 cells. The expression of IL-8 was significantly increased, especially at 12 h time point; and the expression of IL-4 was decreased in H. pylori-infected GES-1 cells. After H. pylori-infected GES-1 cells were treated with RC-derived diterpenoid C of different concentrations and amoxicillin, the expression of IL-8 was decreased at 12, 24, 48, 72 h points (P < 0.01), especially in high-concentration diterpenoid C (20 µg/mL) group; and the expression of IL-4 was increased, especially in moderate and high-concentration diterpenoid C (10 and 20 µg/mL) groups. RC-derived diterpenoid C had the inhibitory effects on H. pylori-induced p65 translocation from cytoplasm into cell nucleus, H. pylori-stimulant IkBα degradation, the phosphorylation of p65 and IkBα, and the expression of IKKα and IKKß proteins. CONCLUSION: RC-derived diterpenoid C can block NF-κB signal pathway, effectively reducing the secretion of H. pylori-induced proinflammatory cytokine and increasing the secretion of anti-inflammatory cytokine.

RESUMO

OBJECTIVE: To examine the efficacy of muscovite on non-steroidal anti-inflammatory drug (NSAID) associated intestinal injury in rats, and its influences on the expressions of inflammatory factors, tumor necrosis factor-alpha (TNF-alpha) and nuclear factor-kappaB (NF-kappaB), for researching its possible mechanism of intestinal mucosal protection. METHODS: NSAID associated intestinal injury in rat was induced by intra-gastric infusion of diclofenac. Twenty-four male Sprague-Dawley rats were randomly and equally assigned to three groups: normal control group, model control group and Muscovite group, 8 in each group. The normal control group received physiological saline 1 mL/100 g and the other two groups received diclofenac 7.8 mg/kg respectively every day for 5 days; while to the Muscovite group, Muscovite 120 mg/kg was gastric infused once on the day before modeling, followed with 120 mg/kg per day, given an hour before diclofenac infusion in the modeling days. All rats were killed on the 6th day, their gross changes and histological injury of intestinal mucosa were observed and scored, serum level of TNF-alpha was assayed in radioimmunoassay and NF-kappaB activity was determined by immunohistochemistry. RESULTS: The small dosage diclofenac administration can cause intestinal damage, revealing obviously erythema, erosion, multiple ulcer, intestinal stricture, even perforation, etc. Intestinal injury in the Muscovite group was obviously milder than that in the model control group, only showed changes of local congestion, edema and erosion. The scores of gross and histological intestinal features in the model control group were 4.38 +/- 1.41 and 4.00 +/- 1.85, while in the Muscovite group were 1.25 +/- 1.58 and 1.75 +/- 0.71, respectively, all higher than those in the normal control group (0.00 +/- 0.00 and 0.00 +/- 0.00, P < 0.01 and P < 0.05), respectively, but the elevation in the model control group were more significant (P < 0.05). Similar results were shown in comparisons of TNF-alpha and NF-kappaB levels between groups, the values were 6.19 +/- 2.76 and 1.38 +/- 1.19 in normal control; 22.20 +/- 5.42 and 5.75 +/- 0.46 in model control; 9.61 +/- 4.02 and 0.13 +/- 0.35 in the Muscovite group, respectively (all P < 0.01). CONCLUSION: Muscovite could effectively reduce the NSAID associated intestinal mucosal injury by inhibiting the activity of NF-kappaB in intestinal mucosa, and down-regulating the expression of TNF-alpha in blood plasma, so muscovite is proved to have protective function for intestine.
