Previously, we reported that the hot water extract of Hydrangea serrata leaves (WHS) and its active component, hydrangenol, possess in vitro and in vivo effects on skin wrinkles and moisturization. We conducted a randomized, double-blind, placebo-controlled trial to clinically evaluate the effect of WHS on human skin. Participants (n = 151) were randomly assigned to receive either WHS 300 mg, WHS 600 mg, or placebo, once daily for 12 weeks. Skin wrinkle, hydration, elasticity, texture, and roughness parameters were assessed at baseline and after 4, 8, and 12 weeks. Compared to the placebo, skin wrinkles were significantly reduced in both WHS groups after 8 and 12 weeks. In both WHS groups, five parameters (R1–R5) of skin wrinkles significantly improved and skin hydration was significantly enhanced when compared to the placebo group after 12 weeks. Compared with the placebo, three parameters of skin elasticity, including overall elasticity (R2), net elasticity (R5), and ratio of elastic recovery to total deformation (R7), improved after 12 weeks of oral WHS (600 mg) administration. Changes in skin texture and roughness were significantly reduced in both WHS groups. No WHS-related adverse reactions were reported. Hence, WHS could be used as a health supplement for skin anti-aging.

Background Iota-Carrageenan (I-C) is a sulfate polysaccharide synthesized by red algae, with demonstrated antiviral activity and clinical efficacy as nasal spray in the treatment of common cold. In vitro, I-C inhibits SARS-CoV-2 infection in cell culture. Methods This is a pragmatic multicenter, randomized, double-blind, placebo-controlled trial assessing the use of a nasal spray containing I-C in the prophylaxis of COVID-19 in hospital personnel dedicated to care of COVID-19 patients. Clinically healthy physicians, nurses, kinesiologists and others medical providers were assigned in a 1:1 ratio to receive four daily doses of I-C spray or placebo for 21 days. The primary end point was clinical COVID-19, as confirmed by reverse-transcriptase-polymerase-chain-reaction testing, over a period of 21 days. The trial is registered at ClinicalTrials.gov (NCT04521322). Findings A total of 394 individuals were randomly assigned to receive I-C or placebo. Both treatment groups had similar baseline characteristics. The incidence of COVID-19 was significantly lower in the I-C group compared to placebo (1.0% vs 5.0%) (Odds Ratio 0.19 (95% confidence interval 0.05 to 0.77; p= 0.03). Workday loss in placebo group compared to I-C were 1.6% days / person (95% CI, 1.0 to 2.2); p <0.0001 There were no differences in the incidence of adverse events across the two groups (17.3% in the I-C group and 15.2% in the placebo group, p= 0.5). Interpretation I-C showed significant efficacy in preventing SARS-CoV-2 infection in hospital personnel dedicated to care patients with COVID-19 disease.

ObjectiveIBS is associated with an intestinal dysbiosis and faecal microbiota transplantation (FMT) has been hypothesised to have a positive effect in patients with IBS. We performed a randomised, double-blind placebo-controlled trial to investigate if FMT resulted in an altered gut microbiota and improvement in clinical outcome in patients with IBS.DesignWe performed this study in 52 adult patients with moderate-to-severe IBS. At the screening visit, clinical history and symptoms were assessed and faecal samples were collected. Patients were randomised to FMT or placebo capsules for 12 days and followed for 6 months. Study visits were performed at baseline, 1, 3 and 6 months, where patients were asked to register their symptoms using the IBS-severity scoring system (IBS-SSS) and IBS-specific quality of life (IBS-QoL). Prior to each visit, faecal samples were collected.ResultsA significant difference in improvement in IBS-SSS score was observed 3 months after treatment (p=0.012) favouring placebo. This was similar for IBS-QoL data after 3 months (p=0.003) favouring placebo. Patients receiving FMT capsules had an increase in faecal microbial biodiversity while placebos did not.ConclusionIn this randomised double-blinded placebo-controlled study, we found that FMT changed gut microbiota in patients with IBS. But patients in the placebo group experienced greater symptom relief compared with the FMT group after 3 months. Altering the gut microbiota is not enough to obtain clinical improvement in IBS. However, different study designs and larger studies are required to examine the role of FMT in IBS.Trial registration numberNCT02788071.

This discussion reviews data from two 3-week, double-blind, placebo-controlled pivotal trials of carbamazepine extended release capsules (CBZ ERC; SPD417.301 and SPD417.304); pooled results from these trials; data from a 3-week, double-blind, placebo-controlled trial in lithium non-responders or non-tolerators (SPD417.302); and additional supportive data from a 6-month, open-label, extension trial (SPD417.303). In addition, information on a retrospective chart review of 600 adolescent and adult bipolar patients on CBZ ERC is presented.In the first large double-blind, placebo-controlled study assessing CBZ ERC in acute mania, manic and mixed bipolar patients from multiple centers were hospitalized and all medications were discontinued. After reaching a stable baseline 2–5 days later, the patients were randomized to CBZ ERC (n=101; 59% with mixed states) or placebo (n=103; 47% with mixed states) for 3 weeks. An aggressive initial titration schedule was implemented, beginning with 200 mg BID and increased by 200 mg/day until good clinical response was achieved or the patient could not tolerate the dosage. Many patients were taking 1,200–1,600 mg/day by the end of week 1. Efficacy was assessed using the Young Mania Rating Scale (YMRS). The Clinical Global Impressions (CGI) scale and the Hamilton Rating Scale for Depression (HAM-D) were also followed.

Objectives. We aimed at evaluating both the efficacy and safety of TJ-54 (Yokukansan) in patients with treatment-resistant schizophrenia. This randomized, multicenter, double-blind, placebo-controlled study was conducted.Methods. One hundred and twenty antipsychotic-treated inpatients were included. Patients were randomized to adjuvant treatment with TJ-54 or placebo. During a 4-week follow-up, psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS).Results. TJ-54 showed a tendency of being superior to placebo in reduction total, positive, and general PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant in both per-protocol set (PPS) and intention-to-treat (ITT). However, in PPS analysis, compared to the placebo group, the TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores for lack of spontaneity and flow of conversation (TJ-54:−0.23±0.08; placebo:−0.03±0.08,P<0.018), tension (TJ-54:−0.42±0.09; placebo:−0.18±0.09,P<0.045), and poor impulse control (TJ-54:−0.39±0.10; placebo:−0.07±0.10,P<0.037).Conclusions. The results of the present study indicate that TJ-54 showed a tendency of being superior to placebo in reduction PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant. However, compared to the placebo group, TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores.

Abstract IntroductionHypertension is one of the most important risk factors for cardiovascular disease, and its treatment and control rates are still low worldwide. The most effective strategy is that patients with hypertension should be diagnosed and treated early. Preliminary studies showed that the Bushen Jiangya granule (BSJY) may suppress ventricular hypertrophy and inflammatory responses, lower blood pressure and protect the target organs of hypertension. We designed a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of BSJY in patients with low-to-medium risk hypertension.Methods and analysisThis trial is a one-center, randomized, double-blind, placebo-controlled study. A total of 260 participants will be randomized in a 1:1 ratio to an experiment group (BSJY plus amlodipine) and a control group (placebo plus amlodipine). The trial cycle will last 8 weeks. The primary outcome is blood pressure, which is reduced to a threshold set out in Guiding Principles for Clinical Research of New Chinese Medicines. The secondary outcomes include the change in 24-h average systolic and diastolic blood pressure, heart rate variability, pharmacogenomic Evaluation, improvement in TCM Syndrome, serum pro-inflammatory/anti-inflammatory cytokines, etc. between the two groups. Safety in medication will also be evaluated. All the data will be recorded in electronic case report forms and analyzed by SPSS V.22.0.Ethics and dissemination This study has been approved by Research Ethics Committee of Guang’anmen Hospital,China Academy of Chinese Medical Sciences in Beijing, China (No. 2019-186-KY-01). The participants are volunteers, understand the process of this trial and sign an informed consent. The results of this study will be disseminated to the public through peer-reviewed journals and academic conferences. DiscussionWe hypothesize that patients with low-to-medium risk hypertension will benefit from BSJY. If successful, this study will provide evidence-based recommendations for clinicians.
