However, if needle insertion depth is deeper than anticipated, needle penetration may cause damage to nerves, arteries and veins. Few clinical studies were done to evaluate the depth of needle length insertion reaching the intended gluteal muscle. The aim of this study was to evaluate the suitable depth of injecting RLAI. Twenty-six patients with schizophrenia were treated with RLAI, and randomly divided into two groups: 50 mm needle inserted group (Group-D, deep insertion, n = 13) and 20 mm needle insertion group (Group-S, shallow insertion, n = 13). For Group-S, the needle length was marked with a spacer at exactly 20 mm. Injections were performed by the psychiatrist or nurse, alternating between the two gluteal sites by double-cross method every two weeks. Clinical psychotic symptoms and injection site reactions were recorded throughout the study period. Experienced psychologists who were blinded from the needle-length experimental variable evaluated patients’ psychotic symptoms using the Positive and Negative Syndrome Scale (PANSS) every two weeks. The plasma 9-hydroxyrisperidone (9-OH-RIS) concentrations were measured every two weeks;comparison data were determined on the 8th week and the 14th week. No significant difference was observed in 9-OH-RIS concentrations, psychotic symptoms, injection site skin reactions of subjects in both groups. However, in Group-D, injection site adverse reactions were confirmed in two subjects (15%). In Group-S, injection site reactions were confirmed in six subjects (46%). Although effective 9-OH-RIS concentrations were obtained with the insertion using both depth, it was concluded that the 50 mm insertion length was more suitable for dorsogluteal IM injections in adult patients with schizophrenia as demonstrated by the incidence of local adverse skin reactions.展开更多

Methods: This randomized, double-blind, placebo-controlled, parallel-group study included 100 healthy male and female adults aged 20 - 64 years. Participants consumed either the G. hansenii GK-1 supplement (9 × 10⁹ cells/day) or a placebo daily for 12 weeks. The impact of temporary mental stress on fatigue in G. hansenii GK-1 was assessed using a Visual Analog Scale (VAS) before the study began and after 12 weeks of supplementation. Results: Subjective fatigue measured by Visual Analog Scale (VAS) showed a significant decrease in fatigue induced by temporary mental stress after 12 weeks of consumption in the G. hansenii GK-1 group compared with the placebo group. No adverse events were attributed to G. hansenii GK-1. These findings confirm that continuous oral ingestion of G. hansenii GK-1 by healthy Japanese adults reduces feelings of fatigue caused by temporary mental stress.展开更多

Methods The trial was a double-blind, placebo-controlled, parallel- group design. The eligible patients were randomized into 2 treatment groups： sarsasapogenin group （sarsasapogenin plus risperidone for 8 weeks, n = 41） and placebo group （risperidone only for 8 weeks, n = 39）. At the baseline, as well as at weeks 2, 4 and 8 of treatment, the therapeutic response was measured by using scales including Positive and Nega- tive Symptoms Scale （PANSS）, Wechsler Memory Scale （WMS）, modified Chinese Wechsler Adult Intelligence Scale （mWAIS）, Clinical Global Impression （CGI） and Brief Psychiatry Rating Scale （BPRS）. The study period for each subject was 8 weeks and duration of overall trial was 2 years. Results Patients treated with sarsasapogenin plus risperidone demonstrated no statistically significant differences in changes in PANSS, WMS or mWAIS score at the end-point of the trial compared with patients treated with placebo plus risperidone. The incidence of treatment-emergent adverse events in patients treated with sarsasapogenin was not different from that observed in placebo group. Conclusion Sarsasapogenin did not augment the efficacy of risperidone in treating negative symptoms dominated schizophrenia. Sarsasapogenin at a dosage of 200 mg per day added to a flexible dosage of risperidone at 2-4 mg per day is safe and well tolerated by patients with negative symptoms dominated schizophrenia.展开更多

Although acupuncture is widely used, until now Western acupuncture studies on RA have not shown conclusive positive results. Acupuncture is regarded as a reflex therapy that has effects on the human autonomic nervous system. By establishing a traditional Chinese medicine（TCM） diagnosis first, the practitioner is able to choose acupoints according to the state of each individual patient.METHODS/DESIGN： We are interested if acupuncture, using a classical diagnostic procedure to allocate acupoints to the patient according to the Shang Han Lun theory, can be effective in relieving pain, improving hand function and increasing health-related quality of life in RA.The authors intend to harmonize TCM diagnosis according to clinical and genetic profiles. Patients with the TCM diagnosis of a so-called Turning Point syndrome will be followed up in a randomized, prospective, double-blind, placebo-controlled, multicenter and three-armed parallel-group study with a standardized treatment in order to optimize potential therapeutic effects of acupuncture on pain, strength and muscle function of patients with RA as well as the influence on inflammation and quality of life.DISCUSSION： The findings of this study will provide important clinical information about the feasibility and efficacy of acupuncture treatment for RA patients. In addition, it will explore the feasibility of further acupuncture research.TRIAL REGISTRATION NUMBER： Clinical Trials.gov Identifier NCT02553005.展开更多

Methods: 100 healthy participants with recurring infections were randomly assigned to receive either placebo or yeast beta-glucan (Yestimun?;n = 50 each group) over a period of 26 weeks. The subjects had to document each common cold episode in a diary, and rate 6 predefined infections symptoms on a 3-point rating scale during an infection period, resulting in an infection score. The common cold episodes were confirmed by the investigators. Results: A total of 171 common cold episodes were documented. Of these, 76 were experienced by 38 subjects in the beta-glucan group and 96 were experienced by 48 subjects in the placebo group (p = 0.406). The beta-glucan group had significantly more subjects without incidences of common cold than the placebo group (15.6% vs 2.0%;p = 0.019). During the most intense infection season (first 13 weeks of the study), the beta-glucan group had significantly less infections compared to placebo (p = 0.02). Beta-glucan significantly reduced the typical cold symptoms (“sore throat and/or difficulty swallowing”, “hoarseness and/or cough” and “runny nose”) as opposed to placebo. Conclusion: The present study demonstrates a prophylactic effect of yeast beta-glucan on the occurrence of common colds as opposed to placebo. In addition, when these episodes occurred, they were from the beginning less pronounced and subsided faster.展开更多

Methods： Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, enabling calculation of obstruction using commonly used grading systems, such as the urethral resistance algorithm, the Abrams-Griffith （AG） number and the Schaefer linear nomogram. Results： There were statistically significant differences between the methods in the mean values of maximum flow rate （P 〈 0.05）, detrusor pressure at the maximum flow （P 〈 0.01）, urethral resistance algorithm （P 〈 0.01）, AG number （P 〈 0.01） and maximum cystic capacity （P 〈 0.01）. Of the men in the study, 10 （43.5%） remained in the same Schaefer class with both methods and 18 （78.3%） in the same AG number area. Using the transurethral method, 12 （52.2%） men increased their Schaefer class by one and 1 （4.3%） by two. There were also differences between the suprapubic and transurethral methods using the AG number： 4 （17.4%） men moved from a classification of equivocal to obstructed and 1 （4.3%） from unobstructed to equivocal. Conclusion： The differences between the techniques for measuring intravesical pressure alter the grading of obstruction determined by several of the commonly used classifications. An 8 F transurethral catheter significantly increases the likelihood of a diagnosis of bladder outlet obstruction when compared with the suprapubic method.展开更多

The trial was designed as a double-blind, randomized dermatological study in 150 outpatients with Herpes labialis. The primary parameter was the duration in days until painless incrustation in 50% or 90% of the patients (observable in 121 patients). Secondary parameters were local pain (assessed on a visual analogue scale), itching, burning and tension/ swelling on a verbal rating scale, and tolerability. Visits were performed on days 2/3, 5/6 and 8/9. Best efficacy results with shortest healing time (3.4 and 5.4 days in the 50th and 90th percentile, respectively;p = 0.008 vs. 1% and 0.09 vs. 0.1%) and good tolerability were observed with the 0.5% concentration. All three concentrations achieved highly significant therapeutic results in comparison with baseline values (p < 0.0005) for all secondary parameters as early as day 2/3. Analgesia was the most prominent effect for the patients. Conclusion: The 0.5 % concentration of propolis special extract GH 2002 in a lip balm was found to have the best risk-benefit ratio for the treatment of Herpes labialis.展开更多

Both at the entry to the study and at the end of the treatment, seven months later, the subjects were examined, with an emphasis on the frequency and distribution of proliferating epithelial cells of the esophagus. Patterns of cell proliferation was defined by dividing the esophageal epithelium into cell columns oriented perpendicularly to the basal cell layer and by comparing the numbers and fractions of tritiated thymidine-labeled epithelial cells in the various cell columns and cell compartments.Before dietary supplementation with calcium, the profile of proliferating epithelial cells in the esophageal compartments in calcium group is similar to that in the placebo group, which is comparable to that previously observed in subjects with high risk for esophageal cancer. Seven months after supplementation having been started, in calcium group, proliferation was significantly reduced and the profile of the esophageal columns approached to that previously observed in subjects at low risk for esophageal cancer, however, in the placebo group, the proliferation and profile maintain at the same level as that before supplementation. Our findings indicate that oral calcium supplementation induces a more quiescent equilibrium in epithelial-cell proliferation in the esophageal mucosa of the subjects at high-risk for esophageal cancer, similar to that observed in subjects at low risk.展开更多

Subjects who d...A randomized, double-blind, placebo-controlled clinical trial in Japanese habitual drinkers was conducted to evaluate the efficacy of Lactobacillus brevis SBC8803 to alleviate adverse effect of alcohol. Subjects who drank habitually and had moderately higher levels of gamma-glutamyl transferase (GGT) (50 - 100 IU/L) were enrolled. The levels of transaminases in these subjects were almost within normal levels (aspartate transaminase (AST) <30 IU/L and alanine transaminase (ALT) <40 IU/L). Either the capsules containing placebo (n = 23) or 130 mg (4.0 × 1010 colony-forming units) of live L. brevis SBC8803 (n = 22) per day were administered for the continuous eight weeks (56 days). During the period, the subjects both in test group and placebo groups have kept each drinking behavior as usual. Regarding lipid metabolism, triacylglycerol (TG) levels in the male test group significantly decreased at week 4 as compared with week 0. Biomarkers of hepatocytes-damage;AST and ALT levels showed no significant differences between the pla- cebo and test groups at both weeks 4 and 8. Oxidative stress marker;GGT at weeks 4 was significantly lower in the test group than that in the placebo group (p = 0.017), but not at weeks 8. However, taking a reduced rate of GGT at weeks 8 comparing with that at week 0, that in the test group showed larger value comparing with that in the placebo group. These data about TG and GGT suggest that, although efficacy of L. brevis SBC8803 is limited in this study, intake of the probiotic may alleviate alcoholic influence in lipid metabolism and oxidative stress.展开更多

文摘In some cases, if the insertion depth is shallower than expected, intramuscular (IM) injection of risperidone long-acting injectable (RLAI) may not penetrate the muscle fascia. However, if needle insertion depth is deeper than anticipated, needle penetration may cause damage to nerves, arteries and veins. Few clinical studies were done to evaluate the depth of needle length insertion reaching the intended gluteal muscle. The aim of this study was to evaluate the suitable depth of injecting RLAI. Twenty-six patients with schizophrenia were treated with RLAI, and randomly divided into two groups: 50 mm needle inserted group (Group-D, deep insertion, n = 13) and 20 mm needle insertion group (Group-S, shallow insertion, n = 13). For Group-S, the needle length was marked with a spacer at exactly 20 mm. Injections were performed by the psychiatrist or nurse, alternating between the two gluteal sites by double-cross method every two weeks. Clinical psychotic symptoms and injection site reactions were recorded throughout the study period. Experienced psychologists who were blinded from the needle-length experimental variable evaluated patients’ psychotic symptoms using the Positive and Negative Syndrome Scale (PANSS) every two weeks. The plasma 9-hydroxyrisperidone (9-OH-RIS) concentrations were measured every two weeks;comparison data were determined on the 8th week and the 14th week. No significant difference was observed in 9-OH-RIS concentrations, psychotic symptoms, injection site skin reactions of subjects in both groups.

文摘Objective: This study assessed the effects of consuming acetic acid bacteria (Gluconacetobacter hansenii GK-1) for 12 weeks on fatigue induced by temporary mental stress. Methods: This randomized, double-blind, placebo-controlled, parallel-group study included 100 healthy male and female adults aged 20 - 64 years. Participants consumed either the G. hansenii GK-1 supplement (9 × 10⁹ cells/day) or a placebo daily for 12 weeks. The impact of temporary mental stress on fatigue in G. hansenii GK-1 was assessed using a Visual Analog Scale (VAS) before the study began and after 12 weeks of supplementation. Results: Subjective fatigue measured by Visual Analog Scale (VAS) showed a significant decrease in fatigue induced by temporary mental stress after 12 weeks of consumption in the G. hansenii GK-1 group compared with the placebo group. No adverse events were attributed to G. hansenii GK-1. These findings confirm that continuous oral ingestion of G. hansenii GK-1 by healthy Japanese adults reduces feelings of fatigue caused by temporary mental stress.

文摘Objective To identify whether sarsasapogenin, a sapogenin from the Chinese medicinal herb Anemarrhena Asphodeloides Bunge, would augment the efficacy of risperidone and significantly improve cognitive functions in patients with negative symptoms dominated schizophrenia. Methods The trial was a double-blind, placebo-controlled, parallel- group design. The eligible patients were randomized into 2 treatment groups： sarsasapogenin group （sarsasapogenin plus risperidone for 8 weeks, n = 41） and placebo group （risperidone only for 8 weeks, n = 39）. At the baseline, as well as at weeks 2, 4 and 8 of treatment, the therapeutic response was measured by using scales including Positive and Nega- tive Symptoms Scale （PANSS）, Wechsler Memory Scale （WMS）, modified Chinese Wechsler Adult Intelligence Scale （mWAIS）, Clinical Global Impression （CGI） and Brief Psychiatry Rating Scale （BPRS）. The study period for each subject was 8 weeks and duration of overall trial was 2 years. Results Patients treated with sarsasapogenin plus risperidone demonstrated no statistically significant differences in changes in PANSS, WMS or mWAIS score at the end-point of the trial compared with patients treated with placebo plus risperidone. The incidence of treatment-emergent adverse events in patients treated with sarsasapogenin was not different from that observed in placebo group. Conclusion Sarsasapogenin did not augment the efficacy of risperidone in treating negative symptoms dominated schizophrenia. Sarsasapogenin at a dosage of 200 mg per day added to a flexible dosage of risperidone at 2-4 mg per day is safe and well tolerated by patients with negative symptoms dominated schizophrenia.
文摘Through the questionnaire survey and comparative studies on tourist satisfaction of tourism services among three world heritage sites,i.e.Huangshan Mountain,Lushan Mountain and Wuyi Mountain,this study pointed out the problems in tourism services of three scenic areas and then put forward relevant countermeasures for the management of scenic areas.
文摘BACKGROUND： Rheumatoid arthritis（RA） is a systemic inflammatory disease characterized by functional disability and pain. Although acupuncture is widely used, until now Western acupuncture studies on RA have not shown conclusive positive results. Acupuncture is regarded as a reflex therapy that has effects on the human autonomic nervous system. By establishing a traditional Chinese medicine（TCM） diagnosis first, the practitioner is able to choose acupoints according to the state of each individual patient.METHODS/DESIGN： We are interested if acupuncture, using a classical diagnostic procedure to allocate acupoints to the patient according to the Shang Han Lun theory, can be effective in relieving pain, improving hand function and increasing health-related quality of life in RA.The authors intend to harmonize TCM diagnosis according to clinical and genetic profiles. Patients with the TCM diagnosis of a so-called Turning Point syndrome will be followed up in a randomized, prospective, double-blind, placebo-controlled, multicenter and three-armed parallel-group study with a standardized treatment in order to optimize potential therapeutic effects of acupuncture on pain, strength and muscle function of patients with RA as well as the influence on inflammation and quality of life.DISCUSSION： The findings of this study will provide important clinical information about the feasibility and efficacy of acupuncture treatment for RA patients. In addition, it will explore the feasibility of further acupuncture research.TRIAL REGISTRATION NUMBER： Clinical Trials.gov Identifier NCT02553005.
文摘Purpose: In a placebo-controlled, double-blind, randomized clinical trial, the effect of an insoluble yeast beta-glucan preparation on the incidences of common colds and its effect on common cold symptoms were compared to placebo. Methods: 100 healthy participants with recurring infections were randomly assigned to receive either placebo or yeast beta-glucan (Yestimun?;n = 50 each group) over a period of 26 weeks. The subjects had to document each common cold episode in a diary, and rate 6 predefined infections symptoms on a 3-point rating scale during an infection period, resulting in an infection score. The common cold episodes were confirmed by the investigators. Results: A total of 171 common cold episodes were documented. Of these, 76 were experienced by 38 subjects in the beta-glucan group and 96 were experienced by 48 subjects in the placebo group (p = 0.406). The beta-glucan group had significantly more subjects without incidences of common cold than the placebo group (15.6% vs 2.0%;p = 0.019). During the most intense infection season (first 13 weeks of the study), the beta-glucan group had significantly less infections compared to placebo (p = 0.02). Beta-glucan significantly reduced the typical cold symptoms (“sore throat and/or difficulty swallowing”, “hoarseness and/or cough” and “runny nose”) as opposed to placebo. Conclusion: The present study demonstrates a prophylactic effect of yeast beta-glucan on the occurrence of common colds as opposed to placebo. In addition, when these episodes occurred, they were from the beginning less pronounced and subsided faster.
文摘Aim： To compare the use of the suprapubic puncture method versus the transurethral method in pressure-flow studies in patients with benign prostatic hyperplasia. Methods： Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, enabling calculation of obstruction using commonly used grading systems, such as the urethral resistance algorithm, the Abrams-Griffith （AG） number and the Schaefer linear nomogram. Results： There were statistically significant differences between the methods in the mean values of maximum flow rate （P 〈 0.05）, detrusor pressure at the maximum flow （P 〈 0.01）, urethral resistance algorithm （P 〈 0.01）, AG number （P 〈 0.01） and maximum cystic capacity （P 〈 0.01）. Of the men in the study, 10 （43.5%） remained in the same Schaefer class with both methods and 18 （78.3%） in the same AG number area. Using the transurethral method, 12 （52.2%） men increased their Schaefer class by one and 1 （4.3%） by two. There were also differences between the suprapubic and transurethral methods using the AG number： 4 （17.4%） men moved from a classification of equivocal to obstructed and 1 （4.3%） from unobstructed to equivocal. Conclusion： The differences between the techniques for measuring intravesical pressure alter the grading of obstruction determined by several of the commonly used classifications. An 8 F transurethral catheter significantly increases the likelihood of a diagnosis of bladder outlet obstruction when compared with the suprapubic method.
文摘A dose-finding study was performed with respect to the clinical applicability and tolerability of three different concentrations of propolis special extract GH 2002 in a lip balm (0.1%, 0.5% and 1%). The trial was designed as a double-blind, randomized dermatological study in 150 outpatients with Herpes labialis. The primary parameter was the duration in days until painless incrustation in 50% or 90% of the patients (observable in 121 patients). Secondary parameters were local pain (assessed on a visual analogue scale), itching, burning and tension/ swelling on a verbal rating scale, and tolerability. Visits were performed on days 2/3, 5/6 and 8/9. Best efficacy results with shortest healing time (3.4 and 5.4 days in the 50th and 90th percentile, respectively;p = 0.008 vs. 1% and 0.09 vs. 0.1%) and good tolerability were observed with the 0.5% concentration. All three concentrations achieved highly significant therapeutic results in comparison with baseline values (p < 0.0005) for all secondary parameters as early as day 2/3. Analgesia was the most prominent effect for the patients. Conclusion: The 0.5 % concentration of propolis special extract GH 2002 in a lip balm was found to have the best risk-benefit ratio for the treatment of Herpes labialis.
文摘A randomized double-blind intervention trial was carried determine whether oral calcium supplementation could lower the proliferation of epithelial cells of the esophagus. 41 subjects identified with precancerous lesions by histopathology were randomized to receive oral supplementation of their conventional diets with 0.6 g of calcium as calcium carbonate or placebo. Both at the entry to the study and at the end of the treatment, seven months later, the subjects were examined, with an emphasis on the frequency and distribution of proliferating epithelial cells of the esophagus. Patterns of cell proliferation was defined by dividing the esophageal epithelium into cell columns oriented perpendicularly to the basal cell layer and by comparing the numbers and fractions of tritiated thymidine-labeled epithelial cells in the various cell columns and cell compartments.Before dietary supplementation with calcium, the profile of proliferating epithelial cells in the esophageal compartments in calcium group is similar to that in the placebo group, which is comparable to that previously observed in subjects with high risk for esophageal cancer. Seven months after supplementation having been started, in calcium group, proliferation was significantly reduced and the profile of the esophageal columns approached to that previously observed in subjects at low risk for esophageal cancer, however, in the placebo group, the proliferation and profile maintain at the same level as that before supplementation. Our findings indicate that oral calcium supplementation induces a more quiescent equilibrium in epithelial-cell proliferation in the esophageal mucosa of the subjects at high-risk for esophageal cancer, similar to that observed in subjects at low risk.
文摘BACKGROUND Previous systematic reviews have consistently reported that coffee consumption has a preventive effect on the occurrence of type 2 diabetes mellitus(T2DM).However,further evaluations between coffee consumption and the risk of T2DM in Asian populations are needed.AIM To conduct a meta-epidemiological study on systematic reviews evaluating the association between coffee consumption and the risk of T2DM in Asian people.METHODS The selection criterion was defined as a population-based prospective cohort study evaluating the association between coffee consumption and the risk of T2DM in Asian populations,reporting the adjusted relative risk(RR)and its 95%confidence interval(CI)for potential confounders.A fixed-effect model metaanalysis was applied to calculate the summary RR and its 95%CI in less than 50%of the I2 value indicating the level of heterogeneity.A two-stage fixed-effects doseresponse meta-analysis(DRMA)was performed to calculate the risk per unit dose(a cup per day).RESULTS A total of seven studies were selected in this meta-epidemiological study.The risk of T2DM in Asian populations was significantly reduced in the highest to the lowest dose group(summary RR=0.73,95%CI:0.66-0.82;I2 value=0.0%).The DRMA showed that drinking one cup of coffee per day reduced the risk of T2DM in Asian populations by 8%(RR=0.92,95%CI:0.90-0.95).CONCLUSION These findings support the conclusion that coffee consumption has a protective effect on the occurrence of T2DM in Asian men and women.
文摘A randomized, double-blind, placebo-controlled clinical trial in Japanese habitual drinkers was conducted to evaluate the efficacy of Lactobacillus brevis SBC8803 to alleviate adverse effect of alcohol. Subjects who drank habitually and had moderately higher levels of gamma-glutamyl transferase (GGT) (50 - 100 IU/L) were enrolled. The levels of transaminases in these subjects were almost within normal levels (aspartate transaminase (AST) <30 IU/L and alanine transaminase (ALT) <40 IU/L). Either the capsules containing placebo (n = 23) or 130 mg (4.0 × 1010 colony-forming units) of live L. brevis SBC8803 (n = 22) per day were administered for the continuous eight weeks (56 days). During the period, the subjects both in test group and placebo groups have kept each drinking behavior as usual. Regarding lipid metabolism, triacylglycerol (TG) levels in the male test group significantly decreased at week 4 as compared with week 0. Biomarkers of hepatocytes-damage;AST and ALT levels showed no significant differences between the pla- cebo and test groups at both weeks 4 and 8. Oxidative stress marker;GGT at weeks 4 was significantly lower in the test group than that in the placebo group (p = 0.017), but not at weeks 8. However, taking a reduced rate of GGT at weeks 8 comparing with that at week 0, that in the test group showed larger value comparing with that in the placebo group. These data about TG and GGT suggest that, although efficacy of L. brevis SBC8803 is limited in this study, intake of the probiotic may alleviate alcoholic influence in lipid metabolism and oxidative stress.

文摘Randomized controlled trials(RCTs) are the gold standard in terms of study design, however, in the surgical setting conducting RCTs can often be unethical or logistically impossible. Case-control studies should become the major study design used in surgical research when RCTs are unable to be conducted and definitely replacing case series which offer little insight into surgical outcomes and disease processes.
