METHODS: A total of 60 patients, hospitalized in a geriatric hospital were enrolled. The intervention consisted of eight acupuncture sessions. The main outcome was the patient's participation rate. Regarding pain, the evaluation was based on pre- and post-treatment variations. As a high proportion of the patients had cognitive impairment, the behavioral pain scale DOLOPLUS-2 was chosen although self evaluation was used wherever possible. RESULTS: The mean age of the patients was 83 years. The acceptance rate was very high (89.6%) and 90% of the patients completed the entire course of treatment. After five weeks, the mean DOLOPLUS score had decreased significantly (P〈0.01). The patients reported improved sleep quality and a reduction in their anxiety symptoms. Furthermore, caregivers noticed a decrease in patient aggressiveness making care easier. CONCLUSION: Our results suggest that acupuncture is highly acceptable and could be very useful in the management of chronic pain when performed in very old frail people with chronic physical and mental disability.

Qigong practice has long been part of daily life in Chinese culture, and has good effects on physical health maintenance. OBJECTIVE: The present work describes the change in balance in young, healthy women after practising Qigong for eight weeks. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: The study took the form of a controlled, randomised longitudinal trial, and involved 30 women aged 18-25 years. The subjects had no prior experience of Qigong or Tai Chi and were unaware of the aims of the study. Subjects were randomly assigned to a Qigong intervention group or a control group. Those in the Qigong intervention group performed "exercises in 20 figures for health and long-life" (Wang Ziping) for 1 h twice per week, for 4 weeks. The control group undertook no exercise at all. MAIN OUTCOME MEASURES: The main outcome measure was the stabilometry values. These were obtained in a unipodal support test, using a plantar pressure platform with optical sensors. RESULTS: The Qigong subjects showed a significant improvement in their stabilometry results (40.1% pre-intervention and 56.4% post-intervention) (P〈0.045), while no improvement was seen in the control group (51.2% pre-intervention and 53.5% post-intervention). At the beginning of the intervention, the stabilometry values recorded for the Qigong intervention group were worse than those recorded for the control group (40.15% and 51.21% respectively; P=0.121). However, a comparison of the post-intervention values between these groups showed that these differences have disappeared (P=0.653). CONCLUSION: Qigong can improve balance in healthy, young women.展开更多

METHODS:We studied hospitalised patients admitted because of acute ulcer bleeding or haemorrhagic gastritis, who had a haematocrit of 27-33% and did not receive blood transfusions.One day after the endoscopic confirmation of cessation of bleeding,they were randomised either to erythropoietin(20 000 IU Epoetin alfa subcutaneously,on days 0,4 and 6)plus iron(100 mg im,on days 1-6,(G_1)or iron only(G_2).Haematocdt was measured on days 0,6,14, 30,45,and 60,respectively. RESULTS:One patient from G_1 and two from G_2 were lost to follow-up.Therefore,14 and 13 patients from G_1 and G_2 respectively were analysed.Demographic characteristics,serum iron,ferritin,total iron binding capacity,reticulocytes,and haernatoait were not significantly different at entry to the study. Median reticulocyte counts were significantly different between groups on day six(G_1:4.0,3.0-6.4 vs G_2:3.5,2.1-4.4%, P=0.03)and median haematocrit on day fourteen [G_1:35.9, 30.7-41.0 vs G_2:32.5,29.5-37.0%(median,range),P=0.04]. CONCLUSION:Erythropoietin administration significantly accelerates correction of anemia after acute ulcer bleeding. The haematocrit gain is equivalent to one unit of transfused blood two weeks after the bleeding episode.展开更多

A single band was placed 5-10 cm proximal to the gastro-esophageal junction over each varix from proximal to distal margin,followed by intravariceal injection of 1.5 % ethoxysclerol (4 ml each) 2 to 3 cm proximal to the gastroesophageal junction on the ligated varices distal to deployed band. EVL was then performed at the injection site. Similarly other varices were also injected and ligated from distal to proximally. In the subsequent sessions, ES alone was performed to sclerose small varices at the gastroesophageal junction.RESULTS: ESL was successfully performed in all patients.A median of 3 (ESL 1, ES 2) sessions (ranged 1-4) were required to eradicate the varices in 9 (90 %) of 10 patients.Recurrence of varices without bleed was seen in 1 patient during a mean follow-up of 10.3 months (ranged 6-15).Two patients died of liver failure. None died of variceal bleeding. None of the patients had procedure related complications.CONCLUSION: ESL may be useful in the fast eradication of esophageal varices. However, randomised controlled trials are required to find out its relative efficacy and impact on variceal recurrence in comparison to ES or EVL.展开更多

All stones removed during cholecystectomy were sent to Houston for x-ray diffraction analysis.Data on age, sex, serum cholesterol,and thepercentage by weight of cholesterol, calcium carbonate, and amorphous material in each stone was entered into a preestablished proforma. Frequencies of the major components of the stones were determined.RESULTS:Sixteen women and ten men aged between 27 and 73 (mean 44.9) years provided stones for the study.The majority of patients (65.38%) had stones with less than 25% of cholesterol.Amorphous material made up more than 50% and 100% of stones from 16 (61.53%) and 9 (34.61%) patients respectively.CONCLUSION:Cholesterol is present in small amounts in a minority of gallstones in Yaounde. Dissolution of gallstones with bile salts is unlikely to be successful.展开更多

METHODS: Eight patients underwent inflatable penile prostheses and 15, testicular prostheses consented to the study. Their medical records were reviewed and a follow-up interview and physical and serological examinations were performed. RESULTS: In patients with penile prostheses, there was no abnormal antinuclear antibody (ANA) or IgM elevation. The serum levels of the rheumatoid factor (RF), C4, IgA and IgG were abnormal in one patient, and the levels of erythrocyte sedimentation rate (ESR) and C3, abnormal in two. Four had elevated IgE. In patients with testicular prostheses, there was no abnormal RF, ANA or IgM. The serum levels of ESR and IgA were abnormal in two, and three had abnormal C4, ten abnormal C3, and eleven decreased IgG. All had increased IgE. Men with penile prostheses had higher serum levels of IgG and IgM than those with testicular prostheses (P=0.001, P=0.016, respectively). The rates of abnormal values of IgE and IgG were higher in men with testicular prostheses than in men with penile prostheses (P=0.008, P=0.009, respectively). Physical examination was normal in all patients and nobody had documented symptoms pertinent to connective-tissue diseases. CONCLUSION: Our findings suggest that the risk of connective-tissue diseases is not higher in patients wearing prostheses as the ANA is negative and there is no apparent manifestation suggestive of connective-tissue diseases.展开更多

Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up.RESULTS: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(P<0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale(FSS) score(P=0.001) after Saam acupuncture using the 5 acupoints.CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.展开更多

OBJECTIVE: To validate the Park sham needle for use as a double-blind control intervention. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: Two different methods were employed. First, a researcher blinded to needle type administered the Park sham or a real needle, chosen at random, on the arms of 16 healthy volunteers. The researcher and the volunteers independently recorded which needle type they thought had been applied at each acupuncture point. Second, 19 patients with shoulder impingement syndrome were randomly assigned to receive acupuncture applied with the real needle or the Park sham needle, once a week for 6 weeks alongside a course of physiotherapy. At the end of the 6 sessions the patients recorded which needle type they thought was being used. The results were analyzed with a Fisher's exact test. This study was carried out in the Outpatient Department of Physiotherapy in Chafing Cross Hospital, London, UK, on healthy volunteers and patients with shoulder impingement pain. The age range was 23 to 54 and 22 to 74 years respectively. RESULTS: Of the healthy volunteers, there was no difference (P=0.23) between the number of needles that were correctly (n=43) or incorrectly identified (n=53). All patients thought that they had received the real needles. The researcher correctly identified all needles that were applied. CONCLUSION: The researcher delivering the acupuncture recognized the needle type. However, both healthy and patient volunteers were blind to the needle type. This demonstrates that the Park sham needle is an effective single-blind control. It should be noted that the number of patients recruited was small and the study was underpowered to detect an effect of treatment.展开更多

OBJECTIVE: The aim of this work was to determine any changes in heart rate variability (HRV) in a study on craniosacral therapy. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a quasi-experimental (controlled) study with cross-over design. In a private practice, measurements were performed on 31 patients with subjective discomforts before and after a control and an intervention period. HRV was determined using a device that requires a measuring time of 140 s and electrode contact only with the fingertips. Main PRIMARY OUTCOME MEASURES: HRV change under the influence of a defined onetime intervention (test intervention) with craniosacral therapy versus control (defined rest period). RESULTS: Standard deviation of all RR-intervals (ms) and total power of RR-interval variability in the frequency range (ms2) were together interpreted as an indicator of test subjects' autonomic nervous activity and as a measure of their ability to cope with demands on their health. Neither of these parameters increased during the control period (P〉0.05), whereas during the test intervention period there was an increase in both (P〈0.05, P〈0.01). Nevertheless, interactions between treatment and the increase were statistically not significant (P〉0.05). No changes were observed in the low frequency/high frequency ratio (sympathetic-vagal balance) in the course of the control or the test intervention period (P〉0.05). CONCLUSION: Craniosacral treatment had a favourable effect on autonomic nervous activity. This in itself is an interesting result, but further research will be needed to distinguish specific effects of craniosacral therapy technique from less specific therapist-client interaction effects.展开更多

Forty-five percent of patients exhibited TC decreasing by more than 10% from baseline and25%ofpatientsexhibited TCdecreasingbymore than 20%. Sixty percent of patients exhibited TG decreasing by more than 20% and 20% of patients exhibited TG decreasing by more than 40%. However,high-density and low-density lipoprotein cholester-ol levels did not change significantly after intervention. No serious adverse events were reported.CONCLUSION: Our findings suggest that CHT plus TCM to treat NAFLD is promising and it might be a new treatment strategy for management of NAFLD.展开更多

文摘AIM: To develop a technique of combined endoscopic sclerotherapy and ligation (ESL) in which both techniques of endoscopic sclerotherapy (ES) and endoscopic variceal ligation (EVL) can be optimally used.METHODS: ESL was performed in 10 patients (age 46.4±7.9;9 males, 1 female) with cirrhosis of liver using sclerotherapy needle and Speedband, Superview multiple band ligater (Boston Scientific, Microvasive, Watertown, MA). A single band was placed 5-10 cm proximal to the gastro-esophageal junction over each varix from proximal to distal margin,followed by intravariceal injection of 1.5 % ethoxysclerol (4 ml each) 2 to 3 cm proximal to the gastroesophageal junction on the ligated varices distal to deployed band. EVL was then performed at the injection site. Similarly other varices were also injected and ligated from distal to proximally. In the subsequent sessions, ES alone was performed to sclerose small varices at the gastroesophageal junction.RESULTS: ESL was successfully performed in all patients.A median of 3 (ESL 1, ES 2) sessions (ranged 1-4) were required to eradicate the varices in 9 (90 %) of 10 patients.Recurrence of varices without bleed was seen in 1 patient during a mean follow-up of 10.3 months (ranged 6-15).Two patients died of liver failure. None died of variceal bleeding. None of the patients had procedure related complications.CONCLUSION: ESL may be useful in the fast eradication of esophageal varices. However, randomised controlled trials are required to find out its relative efficacy and impact on variceal recurrence in comparison to ES or EVL.
文摘AIM:Gallstone disease is increasing in sub-saharan Africa (SSA).In the west, the majority of stones can be dissolved with bile salts,since the major component is cholesterol.This medical therapy is expensive and not readily accessible to poor populations of SSA.It was therefore necessary to analyze the chemical composition of biliary stones in a group of patients,so as to make the case for introducing bile salt therapy in SSA.METHODS: All patients with symptomatic gallstones were recruited in the study. All stones removed during cholecystectomy were sent to Houston for x-ray diffraction analysis.Data on age, sex, serum cholesterol,and thepercentage by weight of cholesterol, calcium carbonate, and amorphous material in each stone was entered into a preestablished proforma. Frequencies of the major components of the stones were determined.RESULTS:Sixteen women and ten men aged between 27 and 73 (mean 44.9) years provided stones for the study.The majority of patients (65.38%) had stones with less than 25% of cholesterol.Amorphous material made up more than 50% and 100% of stones from 16 (61.53%) and 9 (34.61%) patients respectively.CONCLUSION:Cholesterol is present in small amounts in a minority of gallstones in Yaounde. Dissolution of gallstones with bile salts is unlikely to be successful.
文摘AIM: To help clarifying the possibility of connective-tissue diseases in men with penile or testicular prostheses. METHODS: Eight patients underwent inflatable penile prostheses and 15, testicular prostheses consented to the study. Their medical records were reviewed and a follow-up interview and physical and serological examinations were performed. RESULTS: In patients with penile prostheses, there was no abnormal antinuclear antibody (ANA) or IgM elevation. The serum levels of the rheumatoid factor (RF), C4, IgA and IgG were abnormal in one patient, and the levels of erythrocyte sedimentation rate (ESR) and C3, abnormal in two. Four had elevated IgE. In patients with testicular prostheses, there was no abnormal RF, ANA or IgM. The serum levels of ESR and IgA were abnormal in two, and three had abnormal C4, ten abnormal C3, and eleven decreased IgG. All had increased IgE. Men with penile prostheses had higher serum levels of IgG and IgM than those with testicular prostheses (P=0.001, P=0.016, respectively). The rates of abnormal values of IgE and IgG were higher in men with testicular prostheses than in men with penile prostheses (P=0.008, P=0.009, respectively). Physical examination was normal in all patients and nobody had documented symptoms pertinent to connective-tissue diseases. CONCLUSION: Our findings suggest that the risk of connective-tissue diseases is not higher in patients wearing prostheses as the ANA is negative and there is no apparent manifestation suggestive of connective-tissue diseases.

文摘OBJECTIVE: To collect preliminary data on the effects of Saam acupuncture with regard to the immunity in cancer patients.METHODS: Ten cancer patients were analyzed for improvements in immunity. Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up.RESULTS: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(P<0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale(FSS) score(P=0.001) after Saam acupuncture using the 5 acupoints.CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.
文摘OBJECTIVE:Moxibustion has long been thought to promote vital energy or immunity through clinical experience.This study aimed to investigate the clinical effects of indirect moxibustion on antioxidant and immunomodulation in a normal population.METHODS:Twenty-five healthy volunteers with no objective or subjective disorders were recruited.The participants were treated with indirect moxibustion on acupoints Guanyuan(CV 4) and Shenque(CV 8) three times per week for 4 weeks.The serum levels of reactive oxygen species(ROS) and malondialdehyde(MDA),the total antioxidant capacity(TAC),the activities of catalase and superoxide dismutase(SOD),and the total glutathione content were determined before and after the 12th moxibustion.Lymphocyte subpopulations and 42 cytokines in the peripheral blood were analyzed using flow cytometry and antibody array,respectively.RESULTS:Compared with the initial time point,the serum levels of ROS and MDA were significantly lowered by moxibustion,while TAC was increased(P<0.01 for all).A significant increase was observed in catalase activity(P<0.05),but not in SOD or total glutathione.There were no significant changes in lymphocyte subpopulations or cytokines in the peripheral blood.Fifteen of 25 participants reported at least one symptom in which they felt subjective improvement after moxibustion.CONCLUSION:Indirect moxibustion on acupoints CV 4 and CV 8 improved the antioxidant defense system,which may be a mechanism explaining the clinical effects of moxibustion.

文摘BACKGROUND: When performing clinical trials involving acupuncture, it can be difficult to choose a placebo control. OBJECTIVE: To validate the Park sham needle for use as a double-blind control intervention. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: Two different methods were employed. First, a researcher blinded to needle type administered the Park sham or a real needle, chosen at random, on the arms of 16 healthy volunteers. The researcher and the volunteers independently recorded which needle type they thought had been applied at each acupuncture point. Second, 19 patients with shoulder impingement syndrome were randomly assigned to receive acupuncture applied with the real needle or the Park sham needle, once a week for 6 weeks alongside a course of physiotherapy. At the end of the 6 sessions the patients recorded which needle type they thought was being used. The results were analyzed with a Fisher's exact test. This study was carried out in the Outpatient Department of Physiotherapy in Chafing Cross Hospital, London, UK, on healthy volunteers and patients with shoulder impingement pain. The age range was 23 to 54 and 22 to 74 years respectively. RESULTS: Of the healthy volunteers, there was no difference (P=0.23) between the number of needles that were correctly (n=43) or incorrectly identified (n=53). All patients thought that they had received the real needles. The researcher correctly identified all needles that were applied. CONCLUSION: The researcher delivering the acupuncture recognized the needle type. However, both healthy and patient volunteers were blind to the needle type. This demonstrates that the Park sham needle is an effective single-blind control. It should be noted that the number of patients recruited was small and the study was underpowered to detect an effect of treatment.
文摘BACKGROUND: Subjective discomforts in a preclinical range are often due to imbalanced autonomic nervous system activity, which is a focus of craniosacral therapy. OBJECTIVE: The aim of this work was to determine any changes in heart rate variability (HRV) in a study on craniosacral therapy. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a quasi-experimental (controlled) study with cross-over design. In a private practice, measurements were performed on 31 patients with subjective discomforts before and after a control and an intervention period. HRV was determined using a device that requires a measuring time of 140 s and electrode contact only with the fingertips. Main PRIMARY OUTCOME MEASURES: HRV change under the influence of a defined onetime intervention (test intervention) with craniosacral therapy versus control (defined rest period). RESULTS: Standard deviation of all RR-intervals (ms) and total power of RR-interval variability in the frequency range (ms2) were together interpreted as an indicator of test subjects' autonomic nervous activity and as a measure of their ability to cope with demands on their health. Neither of these parameters increased during the control period (P〉0.05), whereas during the test intervention period there was an increase in both (P〈0.05, P〈0.01). Nevertheless, interactions between treatment and the increase were statistically not significant (P〉0.05). No changes were observed in the low frequency/high frequency ratio (sympathetic-vagal balance) in the course of the control or the test intervention period (P〉0.05). CONCLUSION: Craniosacral treatment had a favourable effect on autonomic nervous activity. This in itself is an interesting result, but further research will be needed to distinguish specific effects of craniosacral therapy technique from less specific therapist-client interaction effects.
文摘OBJECTIVE: To demonstrate the potential to treat non-alcoholic fatty liver disease(NAFLD) with colon hydrotherapy(CHT) plus Traditional Chinese Medicine(TCM).METHODS: A total of 20 patients were enrolled into the study and received CHT with TCM for 2 weeks.Body mass index(BMI) and levels of serum triglycerides(TG) and total cholesterol(TC) were compared between pre-treatment and post-treatment.RESULTS: Two-week treatment with CHT plus TCM significantly lowered BMI and reduced blood lipids.BMI decreased from 29.5 ± 4.3 to 25.4 ± 1.0, while mean TG levels decreased by 0.70 mmol/L on average from baseline and mean TC levels decreased by0.37 mmol/L. Forty-five percent of patients exhibited TC decreasing by more than 10% from baseline and25%ofpatientsexhibited TCdecreasingbymore than 20%. Sixty percent of patients exhibited TG decreasing by more than 20% and 20% of patients exhibited TG decreasing by more than 40%. However,high-density and low-density lipoprotein cholester-ol levels did not change significantly after intervention. No serious adverse events were reported.CONCLUSION: Our findings suggest that CHT plus TCM to treat NAFLD is promising and it might be a new treatment strategy for management of NAFLD.
文摘OBJECTIVE:To evaluate the effects of feet reflexology versus segmental massage in reducing pain and its intensity, frequency and duration of the attacks in females suffering from migraine.METHODS:Forty eight females aged 33-58, suffering from migraine for 2 to 10 years were included in this study from November 2013 to November2015.The study protocol was carried out in Department of Chronic Diseases at the Regional Hospital in Zywiec.In the reflexology group(RG) the patients received a series of 10 treatments 2 times per week; in the segmental massage group(SMG) the patients received a series of 15 treatments 3 times per week.Pain during migraine attacks was assessed using the visual analog scale(VAS), and headache features such as intensity(IA), frequency(FA) and duration(DA) of attacks were assessed before the treatment, just after the treatment, 3months after the treatment.RESULTS:All variables(VAS, IA, FA and DA) decreased within RG and SMG 3 months after the treatment in compare with the baseline values, and the differences were statistically significant.The differences between groups were also statistically significant.CONCLUSION:Feet reflexology and segmental massage provide a safe alternative for the pharmacological treatment of migraine.The patients with migraine obtain significant health benefits with feet reflexology.
