Abstract Background Acute pharyngitis and tonsillitis are common respiratory diseases for which children seek medical care. Their main clinical manifestation is sore throat which interferes with patients’ quality of life. However, there is no proven effective or safe method to treat it. It is necessary to find an excellent strategy to reduce sore throat and reduce the burden of acute illness. We designed the randomized controlled trial with the characteristics of traditional Chinese medicine (TCM) to determine the clinical positioning of Kai-Hou-Jian spray (children’s type) (KHJS) through evidence-based research. This trial aims to evaluate the immediate analgesic efficacy of KHJS on sore throat caused by acute pharyngitis and tonsillitis (wind-heat syndrome/heat exuberance in lung and stomach syndrome) in children and to observe its safety. Methods/design This is a prospective, multicenter, randomized, double-blind, parallel-group, placebo-controlled trial. It will include 240 children with acute pharyngitis/tonsillitis from 7 study sites across China. All participants are randomly assigned to two parallel treatment groups, one with KHJS and the other with placebo sprays, for 5 consecutive days. The primary outcome is the time of analgesic onset. Secondary outcomes include duration of analgesic effect, area under time curve of 0–3 h Wong-Baker FACES Pain Rating Scale (WBS) score (AUC0-3 h), rate of analgesic onset, rate of disappearance of sore throat, changes of WBS score (in days), effective rate of pharyngeal signs, and effective rate of TCM syndrome. The incidence of adverse events during the trial is the primary safety outcome. In addition, vital signs and laboratory tests before and after medication are monitored. Discussion To our knowledge, this will be the first clinical trial to explore the immediate analgesic efficacy of a Chinese patent medicine spray for acute pharyngitis/tonsillitis induced sore throat in children in a multicenter, randomized, double-blinded, parallel-group, placebo-controlled manner. Not only might it prove the efficacy and safety of KHJS in the treatment of sore throat caused by acute pharyngitis/tonsillitis in children, but it might also provide evidence for the treatment of acute sore throat with Chinese herbal medicine. Trial registration A multicenter, randomized, double-blind, very low-dose, parallel controlled trial for the immediate analgesic effect and safety of Kai-Hou- Jian spray (children's type) in the treatment of sore throat caused by acute pharyngitis and tonsillitis in children.

Therapeutic Gain

AbstractThe pain-relieving efficacy of naproxen and acetylsalicylic acid (ASA) in tonsillectomized patients was compared in a double blind parallel clinical trial comprising 83 patients, among whom 42 were treated with naproxen and 41 with ASA. The patients were treated post-operatively for two days with either naproxen suppositories 500 mg. twice, or ASA effervescent tablets 1000 mg. three times, daily.The therapeutic gain was evaluated by recording the intensity of pain, reduced ability to open the mouth (trismus), consumption of supplementary analgesic (parcetamol), and pain-related sleep disturbances.The statistical analysis of the results revealed no differences in pain intensity, consumption of additional analgesics or pain-related sleep disturbances in the two treatment groups. A considerable degree of trismus was demonstrated in most of the tonsillectomized patients. This reduced ability to open the mouth was gradually overcome in the naproxen group while it remained unchanged in the ASA group, however, no statistical significant difference could be demonstrated. Additionally, no significant positive correlation between pain intensity and trismus was proven. The pain-relieving effect, however, was unsatisfactory in both the naproxen and the ASA group, and clinical controlled trial studies of alternative analgetics in tonsillectomized patients are still to be encouraged.

Abstract Background New therapies are urgently needed for Alzheimer’s disease (AD). Sodium oligomannate (GV-971) is a marine-derived oligosaccharide with a novel proposed mechanism of action. The first phase 3 clinical trial of GV-971 has been completed in China. Methods We conducted a phase 3, double-blind, placebo-controlled trial in participants with mild-to-moderate AD to assess GV-971 efficacy and safety. Participants were randomized to placebo or GV-971 (900 mg) for 36 weeks. The primary outcome was the drug-placebo difference in change from baseline on the 12-item cognitive subscale of the Alzheimer’s Disease Assessment Scale (ADAS-cog12). Secondary endpoints were drug-placebo differences on the Clinician’s Interview-Based Impression of Change with caregiver input (CIBIC+), Alzheimer’s Disease Cooperative Study-Activities of Daily Living (ADCS-ADL) scale, and Neuropsychiatric Inventory (NPI). Safety and tolerability were monitored. Results A total of 818 participants were randomized: 408 to GV-971 and 410 to placebo. A significant drug-placebo difference on the ADAS-Cog12 favoring GV-971 was present at each measurement time point, measurable at the week 4 visit and continuing throughout the trial. The difference between the groups in change from baseline was − 2.15 points (95% confidence interval, − 3.07 to − 1.23; p < 0.0001; effect size 0.531) after 36 weeks of treatment. Treatment-emergent adverse event incidence was comparable between active treatment and placebo (73.9%, 75.4%). Two deaths determined to be unrelated to drug effects occurred in the GV-971 group. Conclusions GV-971 demonstrated significant efficacy in improving cognition with sustained improvement across all observation periods of a 36-week trial. GV-971 was safe and well-tolerated.

Comparative Clinical Trial

Three hundred and twelve patients suffering from painful conditions were admitted to a multicentre, double-blind controlled trial, conducted in general practice in which five analgesics—floctafenine (Idarac), paracetamol, aspirin, dihydrocodeine and pentazocine—were compared. Overall ratings of analgesic effect placed floctafenine first in rank order. Floctafenine was statistically significantly superior in effect to pentazocine but not to the other three agents as far as doctor ratings were concerned; and superior to both pentazocine and dihydrocodeine in the opinion of patients. Fewer patients experienced side-effects on floctafenine than on the other four analgesics and this difference between floctafenine and pentazocine, and floctafenine and dihydrocodeine was statistically significant.

AbstractCognitive aging creates major individual and societal burden, motivating search for treatment and preventive care strategies. Behavioural interventions can improve cognitive performance in older age, but effects are small. Basic research has implicated dopaminergic signalling in plasticity. We investigated whether supplementation with the dopamine-precursor L-dopa improves effects of cognitive training on performance. Sixty-three participants for this randomised, parallel-group, double-blind, placebo-controlled trial were recruited via newspaper advertisements. Inclusion criteria were: age of 65–75 years, Mini-Mental State Examination score >25, absence of serious medical conditions. Eligible subjects were randomly allocated to either receive 100/25 mg L-dopa/benserazide (n = 32) or placebo (n = 31) prior to each of twenty cognitive training sessions administered during a four-week period. Participants and staff were blinded to group assignment. Primary outcomes were latent variables of spatial and verbal fluid intelligence. Compared to the placebo group, subjects receiving L-dopa improved less in spatial intelligence (−0.267 SDs; 95%CI [−0.498, −0.036]; p = 0.024). Change in verbal intelligence did not significantly differ between the groups (−0.081 SDs, 95%CI [−0.242, 0.080]; p = 0.323). Subjects receiving L-dopa also progressed slower through the training and the groups displayed differential volumetric changes in the midbrain. No statistically significant differences were found for the secondary cognitive outcomes. Adverse events occurred for 10 (31%) and 7 (23%) participants in the active and control groups, correspondingly. The results speak against early pharmacological interventions in older healthy adults to improve broader cognitive functions by targeting the dopaminergic system and provide no support for learning-enhancing properties of L-dopa supplements in the healthy elderly. The findings warrant closer investigation about the cognitive effects of early dopamine-replacement therapy in neurological disorders. This trial was preregistered at the European Clinical Trial Registry, EudraCT#2016-000891-54 (2016-10-05).

IntroductionAfter stroke, hemiplegia, dysphasia and facial paralysis can manifest during the convalescent period. Currently, no Chinese patent medicine (CPM) is previously reported to cure each of these symptoms primarily, and thus, there are no relevant instructions for the use of CPM. This study presents a new approach based on comparative effectiveness research to distinguish the curative effects of three CPMs that are often used in stroke convalescence to determine the ideal medicine for the treatment of each symptom.Methods and analysisIn this multicentre and double-blind clinical trial, stratified randomisation is used to group the patients according to their primary symptoms (hemiplegia, dysphasia and facial paralysis). Three strata will be enrolled, with 80 eligible participants included in each stratum. Each stratum will be randomly and equally divided into four groups, and each group will receive one of the following treatments: Naoxuekang, Xinnaoshutong (XNST), Xuesaitong (XST) or placebo. This study will include two stages: the initial treatment period (30 days) and a follow-up period (180 days). Three replicates for each data point will be completed during this trial. The first visit will occur on day 0 after enrolment, the second visit on day 30±2 and the third visit on day 210±5. The Delphi technique is adopted to achieve index weighting, which ensures that the evaluation outcome is patient oriented. The weighted index value will be computed as the final measurement index of the outcome.Ethics and disseminationThis study has been approved by the Medical Ethics Committee of Tianjin University of Traditional Chinese Medicine (registration number TJUTCM-EC20160007). The results will be offered for publication in peer-reviewed journals.Trial registration numberThis trial was registered with the Chinese Clinical Trial Registry (ChiCTR-IOR-17010397).

Treatment Situation

In the six years that have elapsed since the tranquillizing drugs have been introduced for the treatment of mental illness, psychiatrists have been overwhelmed by the multiplicity of drugs, each claimed by its manufacturer to be more effective and less toxic than all the others. Contemporaneously, there has been a demand for the better assessment of the value of therapy in psychiatry with less reliance on clinical impression and more on the controlled trial (Eysenck, 1957; Foulds, 1958). It is quite impossible for each clinician to familiarize himself with each new drug, and it is difficult to carry out a fully-controlled double-blind trial on more than a small proportion of them. Moore (1959) has suggested a centrally-controlled trial of the tranquillizing drugs in schizophrenia by a body such as the Medical Research Council (1954) similar to the study on aspirin and cortisone in rheumatoid arthritis. Difficulties concerning diagnosis, and, probably more important, variations in the environment of the treatment situation which are of so much importance in determining the outcome of a mental illness, militate against the successful pursuance of such a scheme, and do not appear to have been overcome so far.
