Effect of sheep bone protein hydrolysate on promoting calcium absorption and enhancing bone quality in low-calcium diet fed rats.

Calcium deficiency is prone to fractures, osteoporosis and other symptoms. In this study, sheep bone protein hydrolysates (SBPHs) were obtained by protease hydrolysis. A low-calcium-diet-induced calcium-deficiency rat model was established to investigate the effects of SBPHs on calcium absorption and intestinal flora composition. The results showed that an SBPHs + CaCl2 treatment significantly increased the bone calcium content, bone mineral density, trabecular bone volume, and trabecular thickness, and reduced trabecular separation, and changed the level of bone turnover markers (P < 0.05). Supplementation of SBPHs + CaCl2 can remarkably enhance the bone mechanical strength, and the microstructure of bone was improved, and the trabecular network was more continuous, complete, and thicker. Additionally, SBPHs + CaCl2 dietary increased the abundance of Firmicutes and reduced the abundance of Proteobacteria and Verrucomicrobiota, and promoted the production of short chain fatty acids. This study indicated that SBPHs promoted calcium absorption and could be applied to alleviate osteoporosis.

The Herbal Medicine Suanzaoren (Ziziphi Spinosae Semen) for Sleep Quality Improvements: A Systematic Review and Meta-analysis.

BACKGROUND: Sleep disturbances are common and bothersome among cancer and noncancer populations. Suanzaoren (Ziziphi Spinosae Semen) is commonly used to improve sleep, yet its efficacy and safety are unclear. METHODS: We systematically searched PubMed, Cochrane Library, and EMBASE from inception through October 5, 2021, to identify randomized trials of Suanzaoren. We included randomized trials comparing Suanzaoren to placebo, medications, cognitive behavioral therapy (CBT), or usual care for improving sleep outcomes in cancer and noncancer patients with insomnia or sleep disturbance. We performed a risk of bias analysis following Cochrane guidelines. Depending on heterogeneity, we pooled studies with similar comparators using fixed- and random-effects models. RESULTS: We included participants with insomnia disorder (N = 785) or sleep disturbance (N = 120) from 9 trials. Compared with placebo, Suanzaoren led to significant subjective sleep quality improvements in participants with insomnia and patients with sleep disturbance combined (standard mean difference -0.58, 95% CI -1.04, -0.11; P < .01); Compared with benzodiazepines or CBT, Suanzaoren was associated with a significant decrease in insomnia severity (mean difference -2.68 points, 95% CI -5.50, -0.22; P = .03) at 4 weeks in the general population and cancer patients. The long-term effects of Suanzaoren were mixed among trials. Suanzaoren did not increase the incidence of major adverse events. The placebo-controlled studies had a low risk of bias. CONCLUSION: Suanzaoren is associated with short-term patient-reported sleep quality improvements among individuals with insomnia or sleep disturbance. Due to the small sample size and variable study quality, the clinical benefits and harms of Suanzaoren, particularly in the long term, should be further assessed in a sufficiently powered randomized trial.

Effects of vitamin D supplementation on the regulation of blood lipid levels in prediabetic subjects: A meta-analysis.

This meta-analysis aimed to systematically investigate whether vitamin D supplementation reduces blood lipid-total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), and triglyceride (TG)-levels in prediabetic individuals. Pubmed, Web of Science, Cochrane Library, Embase, CNKI, and WANFANG databases were searched for studies published before 13 February 2022 (including 13 February 2022). Five articles were included. The results showed that vitamin D intervention led to a significant reduction in TG compared with control or placebo treatment (-0.42 [-0.59, -0.25], P < 0.001). Subgroup analyses showed that this effect was particularly significant among the studies that included obese subjects (-0.46 [-0.65, -0.28], P < 0.001), the studies that also included men (not only women) (-0.56 [-0.78, -0.34], P < 0.001), and the studies with intervention durations longer than 1 year (-0.46 [-0.65, -0.28], P < 0.001). Both relatively low doses of 2,857 IU/day (-0.65 [-0.92, -0.38], P < 0.001) and relatively high doses of 8,571 IU/day (-0.28 [-0.54, -0.02] P = 0.04) of vitamin D supplementation reduced TG levels, and the effect was observed both in Northern Europe (-0.65 [-0.92, -0.38], P < 0.001) and Asian (-0.25 [-0.48, -0.03], P = 0.03) country subgroups. No significant effects on TC, HDL-C, and LDL-C were shown. In conclusion, vitamin D supplementation might beneficially affect TG levels in individuals with prediabetes. Particularly longer durations of treatment, more than 1 year, with doses that correct vitamin deficiency/insufficiency, can have a beneficial effect. This meta-analysis was registered at www.crd.york.ac.uk/prospero (CRD42020160780).

Addressing cancer-related fatigue through sleep: A secondary analysis of a randomized trial comparing acupuncture and cognitive behavioral therapy for insomnia.

Background: Fatigue is a troublesome symptom in cancer survivors that often results from disrupted sleep. We sought to assess whether two insomnia-focused non-pharmacological interventions are also effective for improving fatigue. Methods: We analyzed data from a randomized clinical trial comparing cognitive behavioral therapy for insomnia (CBT-I) versus acupuncture for insomnia among cancer survivors. Participants were 109 patients who reported insomnia and moderate or worse fatigue. Interventions were delivered over eight weeks. Fatigue was evaluated at baseline, week 8, and week 20 using the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). We used both mediation analysis and t-tests to explore the extent to which fatigue reduction was attributable to insomnia response. Results: Compared to baseline, both CBT-I and acupuncture produced significant reductions in total MFSI-SF scores at week 8 (-17.1 points; 95% confidence interval [CI]: -21.1 to -13.1, and -13.2 points; 95% CI: -17.2 to -9.2, respectively, all p<0.001) and week 20 (-14.6 points; 95% CI: -18.6 to -10.6, and -14.2 points; 95% CI: -18.1 to -10.3. respectively, all p<0.001), with no significant between-group differences. MFSI-SF total scores at week 8 were significantly associated with sleep improvements in both CBT-I and acupuncture groups (p<0.001 and p=0.011, respectively). Insomnia responders demonstrated significantly greater improvements in mean MFSI-SF total scores compared with non-responders in the CBT-I group (p=0.016) but not in the acupuncture group. Conclusion: CBT-I and acupuncture produced similar, clinically meaningful, and durable fatigue reductions in cancer survivors with insomnia, primarily through improvements in sleep. Acupuncture may also reduce fatigue through additional pathways.

Ginseng and Ginseng Herbal Formulas for Symptomatic Management of Fatigue: A Systematic Review and Meta-Analysis.

Objectives: Ginseng has been widely used in fatigue management. However, its efficacy on fatigue remains unclear. This study aimed to assess the efficacy and safety of ginseng and ginseng herbal formulas for fatigue in randomized clinical trials (RCTs). Methods: The authors searched PubMed, Embase, Cochrane, Web of Science, and Allied and Complementary Medicine Database (AMED) databases from inception to July 6, 2022. Outcomes included fatigue severity, quality of life (QoL), and adverse events (AEs). Quality of evidence was assessed using the Cochrane Risk of Bias Tool. They pooled all included data and performed subgroup analysis by fatigue type, assessment instrument, and ginseng type. Results: The authors included 19 RCTs. Pooled analyses found no significant reduction in fatigue severity with ginseng versus controls (standardized mean difference [SMD]: -0.36, 95% confidence interval [CI]: -0.82 to 0.11, p = 0.13). In subgroup analysis, there was significant fatigue reduction with the ginseng herbal formula (SMD: -0.39, 95% CI: -0.66 to -0.13, p = 0.004) and chronic fatigue (CF) (SMD: -0.30, 95% CI: -0.56 to -0.03, p = 0.03) compared to controls. Ginseng produced significant reductions in general (i.e., non-disease-specific) fatigue compared to controls (SMD: -0.48, 95% CI: -0.71 to -0.25, p < 0.0001). Ginseng was associated with a trend toward QoL improvement (p = 0.05) and did not increase AEs compared with controls. Effect sizes were small. Conclusion: Ginseng herbal formulas improved fatigue severity compared to controls, especially among patients with CF, but with a small effect size. Rigorous RCTs as well as guidelines for standard ginseng usage are needed to further evaluate the effects of ginseng for fatigue and ensure proper use.

Impact of Baseline Expectancy on Outcome Prediction of Real and Sham Acupuncture for Persistent Chemotherapy-Induced Peripheral Neuropathy Pain in Solid Tumor Survivors: A Secondary Analysis of a Randomized Clinical Trial.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) pain significantly worsens cancer survivors' quality of life. Expectancy may play an important role in acupuncture response. We sought to explore whether expectancy predicts pain outcome in real acupuncture (RA) and sham acupuncture (SA) in cancer survivors. METHODS: We analyzed data from a randomized clinical trial that evaluated the effect of RA on CIPN symptoms compared to SA and wait list control (WLC) in 75 cancer survivors. This secondary analysis was limited to CIPN pain measured by the Numeric Rating Scale (NRS), graded from 0 to 10. Interventions were delivered over 8 weeks. SA was implemented using a combination of non-acupuncture points and a non-insertion procedure. Patient expectancy was measured by the Acupuncture Expectancy Scale (AES) 3 times during the study. We used a linear regression model to evaluate if the NRS score was associated with the baseline AES score at the end of treatment (week 8), adjusting for baseline NRS score. RESULTS: AES was similar among 3 groups at baseline (RA: 11.8 ± 2.7; SA: 12.1 ± 3.8.; WLC: 14.6 ± 4.2; P = .062). Baseline AES was not found to be significantly associated with the week 8 NRS score among patients in all RA, SA, and WLC groups (all P > .05). However, we found a trend that higher baseline AES predicted lower NRS score at week 8 in the SA group: a one-point higher score on baseline expectancy was associated with a 0.3-point reduction in NRS pain score (P = .059) at week 8. CONCLUSIONS: The association of baseline expectancy and acupuncture response was similar between RA and SA. However, SA seemed to rely more on expectancy than RA. Further studies with larger sample sizes are needed to confirm this finding.

Does expectancy affect insomnia treatment response in cancer survivors receiving acupuncture and cognitive behavioral therapy?

PURPOSE: Insomnia negatively affects quality of life in cancer survivors. Expectations of insomnia treatment efficacy may influence response to intervention. We sought to determine whether pre-treatment outcome expectancy predicts response to two non-pharmacological interventions for insomnia among cancer survivors. METHODS: We analyzed data from a randomized clinical trial that compared acupuncture versus cognitive behavioral therapy for insomnia (CBT-I) in cancer survivors. Patient expectancy was measured by the Mao Treatment Expectancy Scale (MTES) at baseline. Insomnia severity was assessed using the Insomnia Severity Index (ISI) at treatment completion (week 8). Multivariate linear regression was used to evaluate the associations between pre-treatment expectancy and ISI score at week, 8 adjusting for co-variates. RESULTS: Expectancy for acupuncture and CBT-I were similar at baseline (acupuncture: 13.3 ± 4.0; CBT-I: 13.2 ± 2.9, p = 0.17). Greater baseline expectancy scores were associated with a greater and statistically significant insomnia severity reduction at week 8 in the acupuncture group (beta coefficients [Coef.] = - 0.35, 95% confidence interval [CI] = - 0.6 to - 0.1, p = 0.016) adjusted for co-variates. Baseline expectancy was not statistically associated with insomnia severity reduction in the CBT-I group (Coef. = - 0.2, 95% CI = - 0.7 to 0.2, p = 0.31). High expectancy was significantly associated with greater proportion of treatment responders at week 8 in the acupuncture group (76% vs. 38%, p = 0.001) but not in the CBT-I group (83% vs. 70%, p = 0.21). CONCLUSIONS: Higher pre-treatment outcome expectancy predicted significantly greater insomnia improvement in patients receiving acupuncture but not in those receiving CBT-I. IMPLICATIONS FOR CANCER SURVIVORS: Aligning treatment provision with expected outcomes may lead to personalized non-pharmacological insomnia management for cancer survivors.

Yak (Bos grunniens) milk improves bone mass and microarchitecture in mice with osteoporosis.

The effect of milk on bone health is controversial. In this study, the effects of yak milk in mice with retinoic acid-induced osteoporosis (OP) were evaluated. Yak milk was provided to OP mice as a nutrition supplement for 6 wk. The results showed that yak milk significantly reduced bone turnover markers (tartrate acid phosphatase and alkaline phosphatase). The yak milk treatment was also associated with remarkably increased bone mineral density, bone volume, trabecular thickness, and trabecular number, as well as improved biomechanical properties (maximum load and stress) of the tibia. Furthermore, yak milk mitigated the deterioration of the network and thickness of trabecular bone in treated OP mice compared with the OP model group. The results indicated that yak milk could improve bone mass and microarchitecture through the inhibition of bone resorption in OP mice.

Using recycled coffee grounds for the synthesis of ZIF-8@BC to remove Congo red in water.

Around 6.6 million tons of spent coffee is produced per year, resulting in resources loss and potential environmental risks. Hence, a green technique is required to reuse the spent coffee grains. In this study, coffee grounds were burnt at 900 °C to generate the biochar (BC) for the synthesis of the porous adsorbent (ZIF-8 @BC) by growing ZIF-8 on the surface of BC. We applied the well-prepared ZIF-8 @BC to remove Congo red (CR) in water. The maximum adsorption capacity of ZIF-8 @BC on Congo red in water was up to 1080.4 mg/g, which was significantly higher than that of many different types of BCs reported in previous studies. The reasons for its highly efficient adsorption of CR probably was attributed to metal ions and coordinatively unsaturated sites in the material. Also, BC enabled the less aggregation of ZIF-8 to provide sufficient specific surface area for CR adsorption. From the analysis of the pseudo-second-order kinetic model and Langmuir model, the adsorption of ZIF-8 @BC on CR was a homogeneously chemical adsorption process regulated by electrostatic interaction, π-π stacking and metal coordination.

Aberrant expression of BDNF might serve as a candidate target for cocaine-induced psychosis: insights from bioinformatics analysis and microarray validation.

BACKGROUND: Cocaine use disorder (CUD) and associated psychosis are major public health issues worldwide, along with high relapse outcome and limited treatment options. Exploring the molecular mechanisms underlying cocaine-induced psychosis (CIP) could supply integrated insights for understanding the pathogenic mechanism and potential novel therapeutic targets. AIMS: The aim of the study was to explore common alterations of CUD-schizophrenia-target genes and identify core risk genes contributing to CIP through data mining and network pharmacology approach. METHODS: Target genes of CUD were obtained from GeneCards, Comparative Toxicogenomics Database, Swiss Target Prediction platform and PubChem. Schizophrenia-related target genes were derived from DisGeNET, GeneCards, MalaCards and Online Mendelian Inheritance in Man databases. Then, the overlap genes of these two sets were regarded as risk genes contributing to CIP. Based on these CUD-schizophrenia-target genes, functional annotation and pathway analysis were performed using the clusterProfiler package in R. Protein-protein interaction network construction and module detection were performed based on the Search Tool for the Retrieval of Interacting Genes (STRING) database and Cytoscape software. Gene expression datasets GSE54839 and GSE93577 were applied for data validation and diagnostic capacity evaluation of interested hub genes. RESULTS: A total of 165 CUD-schizophrenia-target genes were obtained. These genes were mainly contributing to chemical synaptic transmission, neuropeptide hormone activity, postsynaptic membrane and neuroactive ligand-receptor interaction pathway. Network analysis and validation analysis indicated that BDNF might serve as an important risk gene in mediating CIP. CONCLUSIONS: This study generates a holistic view of CIP and provides a basis for the identification of potential CUD-schizophrenia-target genes involved in the development of CIP. The abnormal expression of BDNF would be a candidate therapeutic target underlying the pathogenesis of CUD and associated CIP.

The association between carotenoids and subjects with overweight or obesity: a systematic review and meta-analysis.

BACKGROUND: Excess body weight, including overweight and obesity, is one of the major factors influencing human health, and plays an important role in the global burden of disease. Carotenoids serve as precursors of vitamin A-related retinoids, and are considered to have potential effects on many diseases. However, the influence of carotenoids on people with excess body weight is unclear. METHODS: This meta-analysis was conducted to assess the effects of carotenoids on overweight or obese subjects utilizing the available evidence. We searched PubMed, Medline, Cochrane Library, Web of Science and EMBASE databases up to September 2020. Random effects models were used to calculate the standard mean differences (SMDs) and odds ratios (ORs) with their 95% confidence intervals (95% CIs). RESULTS: A total of seven randomized controlled trials and eight observational studies met the inclusion criteria and contained 28 944 subjects and data on multiple carotenoid subgroups, including lycopene, astaxanthin, cryptoxanthin, α-carotene, and ß-carotene. In all included Randomized Controlled Trial (RCT), the intervention duration was 20 days at the shortest and 16 weeks at the longest, and the range of intervention doses was 1.2-60 mg d-1. Our study found that the insufficiency of serum carotenoids was a risk factor for overweight and obesity (OR = 1.73, 95% CI [1.57, 1.91], p < 0.001). Moreover, carotenoid supplementation was significantly associated with body weight reductions (SMD = -2.34 kg, 95% CI [-3.80, -0.87] kg, p < 0.001), body mass index decrease (BMI, SMD = -0.95 kg cm-2, 95% CI [-1.88, -0.01] kg cm-2, p < 0.001) and waist circumference losses (WC, SMD = -1.84 cm, 95% CI [-3.14, -0.54]cm, p < 0.001). CONCLUSION: In summary, the carotenoids show promising effects in overweight or obese subjects. Additional data from large clinical trials are needed.

Cognitive and emotional predictors of real versus sham repetitive transcranial magnetic stimulation treatment response in methamphetamine use disorder.

BACKGROUND AND AIMS: Repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) can effectively reduce cravings in methamphetamine use disorder (MUD). However, a considerable group still fails to respond. Cognitive and emotional disturbance, as well as impulsive features, are widespread in patients with MUD and might mediate the treatment response of rTMS. The purpose of this study is to figure out whether these variables can help predicting patients' responses to rTMS treatment. METHODS: Ninety-seven patients with severe MUD and thirty-one gender- and age-matched healthy subjects were included. Patients were randomized to receive 20 sessions of real or sham rTMS. Intermittent theta burst protocols (iTBS) or sham iTBS were applied every weekday over the DLPFC for 20 daily sessions. Both groups received regular treatment. Craving induced by drug-related cue was measured before and after stimulation. Cognition was evaluated by using the CogState Battery. Baseline characteristics were collected through the Addiction Severity Index, Patient Health Questionnaire-9, General Anxiety Disorder Scale-7, and Barrett Impulsivity Scale-11. RESULTS: Results showed that patients with MUD have worse spatial working memory, problem-solving ability, as well as depression and anxiety symptoms compared with healthy controls. Cognition and emotion differed between responders (craving decrease ≥60%) and non-responders in real rTMS group but not in the sham group. Better cognitive and emotional functions means that patients have higher possibility for better response to real rTMS treatment. CONCLUSIONS: This study suggests that cognitive, emotional and impulsive features could be used to predict the prospective treatment responses of rTMS in patients with MUD.

Ethanolic extract of Cordyceps cicadae exerts antitumor effect on human gastric cancer SGC-7901 cells by inducing apoptosis, cell cycle arrest and endoplasmic reticulum stress.

ETHNOPHARMACOLOGICAL RELEVANCE: Cordyceps cicadae (Miq.) Massee is a traditional Chinese medicine that has been used for approximately 1600 years in China. C. cicadae, a member of the Cordyceps genus, exerts a therapeutic effect on many diseases, such as cancer. OBJECTIVE: This study aimed to evaluate the antineoplasmic activity of C. cicadae and to identify its molecular mechanism of cell death. MATERIALS AND METHODS: The toxicity of the ethanolic extract of C. cicadae (EEC) against different cancer cell lines was determined through MTT assay. Human gastric cancer SGC-7901 cells were treated with EEC for 48 h. Cell morphology was examined by using an Olympus phase-contrast microscope. The cell apoptosis was quantified through Annexin V-FITC/PI staining. Cells were stained with PI and then subjected to flow cytometry for the investigation of cell cycle status. Cells were subjected to mitochondrial membrane potential (MMP) assay after incubation with JC-1 probes and to intracellular Ca2+ measurement through flow cytometry after incubation with Fluo-3 AM fluorescent probes. Western blot analysis was conducted to quantify the expression of proteins related to apoptosis, cell cycle and endoplasmic reticulum stress. High-performance liquid chromatography (HPLC) analysis was performed to analyse the biological activity components of EEC. RESULTS: EEC suppressed the proliferation of SGC-7901 cells and induced the development of abnormal morphological features in a dose-dependent manner. Flow cytometry results indicated that EEC treatment caused cell apoptosis and arrested the cell cycle in the S phase. In addition, EEC treatment triggered MMP depolarization and Ca2+ overloading in the cytosol of SGC-7901 cells. Western blot analysis demonstrated that EEC increased Bax, AIF, caspase-8, caspase-6 and caspase-3 activities and decreased Bcl-2 activity. The release of cytochrome c from mitochondria was associated with mitochondrial dysfunction, which was caused by the activation of the cell surface receptor Fas and the cleavage of PARP. EEC-induced S phase arrest was associated with the up-regulation of E2F1, cyclin A2, cyclin E and p53 expression levels and the down-regulation of CDK2 expression. In addition, EEC increased the expression of endoplasmic reticulum stress-related proteins, such as calpain-1, caspase-12 and caspase-9. HPLC assay results suggested that EEC contained adenine, uridine, adenosine and N6-(2-Hydroxyethyl)-adenosine. CONCLUSION: EEC inhibited the proliferation of SGC-7901 cells by inducing caspase-dependent apoptosis, arresting the cell cycle in the S phase and increasing endoplasmic reticulum stress. This study revealed that C. cicadae is a potential natural source of anticancer drugs.

Traditional Chinese medicine and drug-induced anaphylaxis: data from the Beijing pharmacovigilance database.

Background Traditional Chinese medicine (TCM) is one of the major triggers for drug-induced anaphylaxis (DIA). Objective We aimed to use the Beijing pharmacovigilance database (BPD) to analyze TCM-induced DIAs in Beijing, China. Setting Drug allergy case reports from the BPD provided by the Beijing Center for Adverse Drug Reaction Monitoring. Method Drug allergy cases from January 2004 to December 2014 were adjudicated. DIA triggered by TCMs were analyzed and compared with those triggered by non-TCM drugs by calculating the reported risk ratio (RRR). We also calculated the RRRs based on severe DIA and death outcomes. Main outcome measure TCMs implicated in DIAs were identified and compared with non-TCM drugs. Results TCMs accounted for 1651 (18.2%) of the total 9074 allergic cases, in which 84.4% (1393/1651) were triggered by injections. Of the TCM allergic cases, 8.5% (141) were DIAs and 7.3% (120) were severe DIAs, and three patients died from injections. The RRR between TCMs and non-TCM-induced DIAs was 0.63. When anaphylactic cases were compared between TCMs to the top four non-TCM drug triggers, RRRs were 0.73 (95% CI 0.61-0.87) for antibiotics, 0.36 (95% CI 0.29-0.44) for radiocontrast agents, 0.55 (95% CI 0.43-0.68) for chemotherapeutics, and 0.29 (95% CI 0.23-0.37) for biologics. Compared to TCM oral or topic formulations, TCM injections had higher RRRs in each of the above comparisons. Conclusion TCM was associated with a decreased risk of DIA compared to non-TCM drugs in drug allergy cases, and the risk was higher for TCM injections.

A Newly Designed Mobile-Based Computerized Cognitive Addiction Therapy App for the Improvement of Cognition Impairments and Risk Decision Making in Methamphetamine Use Disorder: Randomized Controlled Trial.

BACKGROUND: Cognitive rehabilitation therapy has been found to improve cognitive deficits and impulse control problems in methamphetamine use disorder (MUD). However, there is limited research regarding this therapy's feasibility when using mobile-based health technologies in supporting recovery from MUD in China. OBJECTIVE: The main aim of this study was to test whether 4 weeks of a newly designed computerized cognitive addiction therapy (CCAT) app can improve cognitive impairments, eliminate drug-related attention bias, and attenuate risk decision-making behaviors in participants with MUD. METHODS: Forty MUD participants were assigned randomly to either the CCAT group (n=20), who received 4 weeks of CCAT plus regular detoxification treatment as usual, or the control group (n=20), who only received the regular detoxification treatment as usual, in drug rehabilitation centers in Shanghai. The CCAT was designed by combine methamphetamine use-related picture stimuli with cognitive training with the aim of improving cognitive function and eliminating drug-related attention bias. The CogState Battery, Delay Discounting Task (DDT), Iowa Gambling Task (IGT), and Balloon Analog Risk Task (BART) were administered face-to-face to all participants before and after CCAT interventions. RESULTS: Forty male patients were recruited. The mean age was 32.70 (SD 5.27) years in the CCAT group and mean 35.05 (SD 8.02) years in the control group. Compared to the control group, CCAT improved working memory in the CCAT group (P=.01). Group×time interactions were observed among DDT, IGT, and BART tasks, with rates of discounting delayed rewards, IGT, and BART scores (P<.001) being reduced among those who received CCAT, whereas no changes were found in the control group. CONCLUSIONS: The newly designed CCAT can help to improve cognitive impairment and impulsive control in MUD. Further study is needed to understand the underlying brain mechanisms of the cognitive therapy. TRIAL REGISTRATION: ClinicalTrials.gov NCT03318081; https://clinicaltrials.gov/ct2/show/NCT03318081 (Archived by WebCite at https://clinicaltrials.gov/ct2/show/NCT03318081).

[Comments on "Effect of Acupuncture vs Sham Acupuncture on Live Births Among Women Undergoing In Vitro Fertilization: A Randomized Clinical Trial " from Journal of the American Medical Association].

In recent years, acupuncture has been used widely as an adjuvant treatment for the in vitro fertilization (IVF). "Effect of Acupuncture vs Sham Acupuncture on Live Births Among Women Undergoing In Vitro Fertilization: A Randomized Clinical Trial " published in Journal of the American Medical Association (JAMA) on May 15, 2018, the research findings do not support the use of acupuncture to improve the rate of live births among the women undergoing IVF. In order to avoid the misunderstanding of the scholars at home and abroad for the clinical effects of acupuncture on IVF assistance, the authors put forward the doubts after the analysis from the following 3 aspects, including the acupuncture scheme, outcomes and result explanation. Additionally, the thinking and suggestions are proposed for the future development of the clinical trials of acupuncture IVF assistance in terms of selecting the proper participants, being abided by the standards of the evidence-based medicine, designing multi-acupuncture schemes and setting up the rational control, as well as conducting the overall analysis of the trial data.

Use of Epinephrine in Patients with Drug-Induced Anaphylaxis: An Analysis of the Beijing Pharmacovigilance Database.

BACKGROUND: Few studies assessing the use of epinephrine in drug-induced anaphylaxis (DIA) in the hospital setting are available. We utilized the Beijing Pharmacovigilance Database (BPD) to evaluate the appropriateness of epinephrine for DIA management. METHODS: DIA cases collected in the BPD from January 2004 to December 2014 were adjudicated and analyzed for demographics, causative drugs, clinical signs, outcomes, initial treatment, route, dosing, and cardiovascular adverse events (CAE) of epinephrine. RESULTS: DIA was primarily caused by antibiotics (38.4%), radiocontrast agents (11.9%), traditional Chinese medicine injections (10.9%), and chemotherapeutic drugs (10.3%). Only 708 (59.5%) patients received epinephrine treatment. Patients who received epinephrine were more likely to experience wheezing (p < 0.001) and respiratory arrest (p < 0.001). Among 518 patients with a complete record of the epinephrine administration route, the percentage of patients receiving it by intramuscular (IM) injection, subcutaneous (SC) injection, intravenous (IV) bolus injection, or IV continuous infusion was 16.9, 31.5, 43.5, and 8.1%, respectively. Among the 427 patients with a record of both the administration route and the dosing, an overdose was more likely with IV bolus (94.1%) in contrast to IM injection (56.6%; p < 0.001) or SC injection (43.7%; p < 0.001). Among the patients analyzed for CAE (n = 349), 17 patients accounted for 19 CAE, and 13 (76.5%) of these patients were overdosed with epinephrine. CONCLUSION: Underuse, inappropriate IV bolus use, and overdosing were the 3 major problems with epinephrine use in DIA in China. Educational training for health care professionals on the appropriate use of epinephrine in managing anaphylactic reactions is suggested.

[Acupuncture with regulating menstruation to promote pregnancy for diminished ovarian reverse: a prospective case series study].

OBJECTIVE: To investigate the effect and safety of acupuncture with regulating menstruation to promote pregnancy for diminished ovarian reverse (DOR). METHODS: According to prospective case series, 46 patients were observed and finally 40 cases were included. The acupoints were ① Baihui (GV 20), Shenting (GV 24), Guanyuan (CV 4) and bilateral Benshen (GB 13), Huangshu (KI 16), Dahe (KI 12), Luanchao (Extra), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Taichong (LR 3) and ② bilateral Shenshu (BL 23) and Ciliao (BL 32). The points in the two groups were used alternately. Acupuncture was given for 3 courses, 12 times as a course and 3 times a week. Before and after treatment, and 3 months after treatment, follicle-stimulating hormone (FSH), follicle-stimulating hormone/luteinizing hormone (FSH/LH), estradiol (E2), antral follicle count (AFC) and TCM symptom score were observed. The safety was evaluated. RESULTS: Compared with before treatment, the levels of FSH, FSH/LH decreased, and the levels of E2 and AFC increased after treatment and at follow-up (all P<0.05). And the TCM symptom scores were significantly lower than those before treatment (both P<0.05). The rate of pregnancy after treatment was 15% (6/40). There was no infection and organ injury. CONCLUSION: Acupuncture with regulating menstruation to promote pregnancy can safely improve the ovarian reserve of patients with DOR.

[Theory and application regarding "stage by stage" acupuncture for diminished ovarian reserve].

Based on a considerable number of ancient literature, clinical experience and modern scientific studies, a comprehensive study was performed on the TCM theory and treatment of diminished ovarian reserve. It was summarized that the two causes of diminished ovarian reserve were deficiency of the kidney essence and incoordination between Chong Vessel and Conception Vessel, so the treatment strategy of "stage by stage" acupuncture was proposed. It was pointed out acupoint selection should be in accordance with physiological basis of menstruation and waxing and waning of yin-yang. Therefore, acupuncture at different acupoints and meridians could regulate yin and yang and promote the normal yin-yang transformation, which could store and discharge the uterus. As a result, the function of ovary is recovered. This method has achieved significant clinical efficacy.

Molecular cloning and differential expression analysis of a squalene synthase gene from Dioscorea zingiberensis, an important pharmaceutical plant.

Diosgenin is a steroid derived from cholesterol in plants and used as a typical initial intermediate for synthesis of numerous steroidal drugs in the world. Commercially, this compound is extracted mainly from the rhizomes or tubers of some Dioscorea species. Squalene synthase (SQS: EC 2.5.1.21) catalyzes the condensation of two molecules of farnesyl diphosphate to form squalene, the first committed step for biosynthesis of plant sterols including cholesterol, and is thought to play an important role in diosgenin biosynthesis. A full-length cDNA of a putative squalene synthase gene was cloned from D. zingiberensis and designated as DzSQS (Genbank Accession Number KC960673). DzSQS was contained an open reading frame of 1,230 bp encoding a polypeptide of 409 amino acids with a predicted molecular weight of 46 kDa and an isoelectric point of 6.2. The deduced amino acid sequence of DzSQS shared over 70 % sequence identity with those of SQSs from other plants. The truncated DzSQS in which 24 amino acids were deleted from the carboxy terminus was expressed in Escherichia coli, and the resultant bacterial crude extract was incubated with farnesyl diphosphate and NADPH. GC-MS analysis showed that squalene was detected in the in vitro reaction mixture. Quantitative real-time PCR analysis revealed that DzSQS was expressed from highest to lowest order in mature leaves, newly-formed rhizomes, young leaves, young stems, and two-year-old rhizomes of D. zingiberensis.
