HTCA: a database with an in-depth characterization of the single-cell human transcriptome.

Single-cell RNA-sequencing (scRNA-seq) is one of the most used single-cell omics in recent decades. The exponential growth of single-cell data has immense potential for large-scale integration and in-depth explorations that are more representative of the study population. Efforts have been made to consolidate published data, yet extensive characterization is still lacking. Many focused on raw-data database constructions while others concentrate mainly on gene expression queries. Hereby, we present HTCA (www.htcatlas.org), an interactive database constructed based on ∼2.3 million high-quality cells from ∼3000 scRNA-seq samples and comprised in-depth phenotype profiles of 19 healthy adult and matching fetal tissues. HTCA provides a one-stop interactive query to gene signatures, transcription factor (TF) activities, TF motifs, receptor-ligand interactions, enriched gene ontology (GO) terms, etc. across cell types in adult and fetal tissues. At the same time, HTCA encompasses single-cell splicing variant profiles of 16 adult and fetal tissues, spatial transcriptomics profiles of 11 adult and fetal tissues, and single-cell ATAC-sequencing (scATAC-seq) profiles of 27 adult and fetal tissues. Besides, HTCA provides online analysis tools to perform major steps in a typical scRNA-seq analysis. Altogether, HTCA allows real-time explorations of multi-omics adult and fetal phenotypic profiles and provides tools for a flexible scRNA-seq analysis.

Durable Effects of Acupuncture for Knee Osteoarthritis: A Systematic Review and Meta-analysis.

PURPOSE OF REVIEW: Knee osteoarthritis (KOA) is a degenerative joint disease which can result in chronic pain and disability. The current interventions available for KOA often fail to provide long-lasting effects, highlighting the need for new treatment options that can offer durable benefits. Previous studies have suggested the efficacy of acupuncture for knee osteoarthritis (KOA) with its durability remaining uncertain. In this review, we aimed to investigate the durability of the efficacy after completion of treatment. RECENT FINDINGS: We performed thorough searches of PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials from inception to November 4, 2023. The outcomes were assessed at all available time points after completion of treatment. Primary outcomes were changes from baseline in pain and function measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function subscales. Secondary outcomes included response rate, overall pain, the WOMAC stiffness subscale, total WOMAC index, and physical and mental health components of 12/36-item Short-Form Health Survey. A total of 10 randomized controlled trials (RCTs) involving 3221 participants were included. Pooled estimates suggested that acupuncture may offer potential improvements in function and overall pain for 4.5 months post-treatment versus sham acupuncture (SA). Acupuncture may provide durable clinically important pain relief and functional improvement up to 5 months post-treatment versus usual care, and up to 6 months post-treatment versus diclofenac. For acupuncture versus no treatment, one trial with large sample size indicated that improvements in pain and function persisted for 3 months post-treatment, while the other trial reported that significant pain reduction and functional improvement were only observed at the end of the treatment, not at 9 months post-treatment. However, acupuncture as adjunct to exercise-based physical therapy (EPT) showed no superiority to SA as an adjunct to EPT or EPT alone up to 11.25 months after completion of treatment. Acupuncture may provide pain alleviation and functional improvements in KOA patients for 3 to 6 months after completion of treatment with a good safety profile.

Durable Effect of Acupuncture for Chronic Neck Pain: A Systematic Review and Meta-Analysis.

OBJECTIVE: Chronic neck pain, a prevalent health concern characterized by frequent recurrence, requires exploration of treatment modalities that provide sustained relief. This systematic review and meta-analysis aimed to evaluate the durable effects of acupuncture on chronic neck pain. METHODS: We conducted a literature search up to March 2024 in six databases, including PubMed, Embase, and the Cochrane Library, encompassing both English and Chinese language publications. The main focus of evaluation included pain severity, functional disability, and quality of life, assessed at least 3 months post-acupuncture treatment. The risk of bias assessment was conducted using the Cochrane Risk of Bias 2.0 tool, and meta-analyses were performed where applicable. RESULTS: Eighteen randomized controlled trials were included in the analysis. Acupuncture as an adjunct therapy could provide sustained pain relief at three (SMD: - 0.79; 95% CI - 1.13 to - 0.46; p < 0.01) and six (MD: - 18.13; 95% CI - 30.18 to - 6.07; p < 0.01) months post-treatment. Compared to sham acupuncture, acupuncture did not show a statistically significant difference in pain alleviation (MD: - 0.12; 95% CI - 0.06 to 0.36; p = 0.63). However, it significantly improved functional outcomes as evidenced by Northwick Park Neck Pain Questionnaire scores 3 months post-treatment (MD: - 6.06; 95% CI - 8.20 to - 3.92; p < 0.01). Although nine studies reported an 8.5%-13.8% probability of adverse events, these were mild and transitory adverse events. CONCLUSION: Acupuncture as an adjunct therapy may provide post-treatment pain relief lasting at least 3 months for patients with chronic neck pain, although it is not superior to sham acupuncture, shows sustained efficacy in improving functional impairment for over 3 months, with a good safety profile.

Effectiveness of electroacupuncture versus prucalopride for women with severe chronic constipation: secondary analysis of a randomized controlled trial.

PURPOSE: Electroacupuncture (EA) is a component alternative therapy for severe chronic constipation (SCC). Women are more vulnerable to SCC and gender might impact the response of patients with functional gastrointestinal disorders to therapy. We performed this secondary analysis to explore the effectiveness and safety of EA compared with prucalopride among women with SCC. METHODS: Based on a multicenter, randomized, noninferiority trial, 446 female patients were randomly assigned to receive 28-session EA (n = 222) over 8 weeks with 24-week follow-up without treatment or to receive prucalopride (n = 224) over 32 consecutive weeks. The primary outcome was the proportion of overall complete spontaneous bowel movements (CSBMs) responders over weeks 1-8, defined as at least three CSBMs per week, and more than an increase of one CSBM from baseline meanwhile for at least 6 weeks during an 8-week treatment period. Secondary outcomes measure sustained CSBM responder, weekly responders, change from baseline in mean weekly CSBMs and SBMs, straining and stool consistency, quality of life, and adverse events (AEs). RESULTS: The proportion of overall responders was 25.23% in the EA group, similar to 25.89% in the prucalopride group, with a between-group difference of - 0.67% (95% CI, - 8.80 to 7.40%; P = 0.872) during an 8-week treatment. In the secondary outcomes, EA and prucalopride groups had no significant difference, except that EA was inferior to prucalopride in improving SBMs. The AEs were less in the EA group than the prucalopride group. CONCLUSION: EA may be a promising and safe treatment for women with SCC; its effect could sustain 24 weeks after treatment stopped.

ARRDC3 polymorphisms may affect the risk of glioma in Chinese Han.

This study ascertained to explore the potential contribution of ARRDC3 polymorphisms in the risk and prognosis of glioma. One thousand sixty-one patients and healthy controls were conducted to assess whether ARDC3 polymorphism was associated with glioma risk and prognosis. Four sites in ARRDC3 were selected and genotyped in MassARRAY platform. The calculated odd ratios and 95% confidence intervals from logistic regression were applied for risk assessment. The relationship between ARRDC3 variants and glioma prognosis was evaluated using log-rank test, Kaplan-Meier analysis, and so on. Also, false-positive report probability (FPRP) and statistical power were also assessed. Our findings suggested the negative role of ARRDC3 polymorphisms in the glioma risk. We also found the effect of candidate SNPs in ARRDC3 on the susceptibility to glioma was dependent on the age, gender, and histology of glioma patients. The results suggested that the genetic polymorphisms of ARRDC3 were related to an increased risk of glioma.

The ADCY9 genetic variants are associated with glioma susceptibility and patient prognosis.

PURPOSE: Genetic factor is a risk factor in glioma occurrence. This study was designed to detect the effect of ADCY9 polymorphisms on glioma risk and prognosis. METHODS: We performed a case-control study of 1080 participants (584 cases and 496 controls) to assess the relationship of ADCY9 polymorphisms with the risk and prognosis of glioma among the Chinses Han population. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed to evaluate the relationship between ADCY9 variants and glioma risk. The correlation of SNPs with survival was analyzed by the Cox regression model. RESULTS: Our study showed that rs2230742 and rs2531992 polymorphisms played protective roles in glioma susceptibility (OR 0.65, p = 0.001; OR 0.73, p = 0.038, respectively). While rs2230742 significantly increased the susceptibility of III-V grade glioma patients (OR 1.50, p = 0.036). Haplotype analysis revealed that Crs879620Ars2230742Ars2230741 haplotype was related to a significantly decreased glioma risk (OR 0.65, p = 0.002). Notably, rs2531995 and rs879620 polymorphisms significantly enhanced death risk in high-grade glioma patients (hazard ratio [HR] 1.36, p = 0.041; HR 1.37, p = 0.042; respectively). For rs2230742 and rs2531992 SNPs, glioma patients had a worse prognosis (HR 2.30, p = 0.021; HR 2.30, p = 0.021; respectively). We further observed that age, chemotherapy, and surgical scope can affect the glioma prognosis. CONCLUSION: We firstly studied the association of ADCY9 variants with glioma risk and prognosis, which might give scientific evidence for exploring the molecular mechanism of glioma.

Genetic variants of CYP4F12 gene are associated with glioma susceptibility.

Glioma is a common and fatal primary malignant tumor of the central nervous system, and its prognosis is poor. To determine the susceptibility markers of gliomas in Chinese population we conducted a genome-wide association study (GWAS) of glioma in the Han Chinese population, with a total of 485 glioma cases and 485 controls. Genotyping was conducted using the Applied Biosystems Axiom Precision Medicine Diversity Array. Besides, we carried out imputation using IMPUTE 2.0 software, and the 1000 Genomes Phase 3 was used as the reference panel. The logistic regression model was used to analyze the association of each SNP with glioma risk, assuming an additive genetic model, which was implemented in PLINK version 1.9. Odds ratio (OR) and 95% confidence interval (CI) were estimated from logistic regression analysis with adjustment for age and gender. The results revealed that the SNP (rs688755) in the exon region of CYP4F12 at 19p13.12 reached genome-wide significance associated with gliomas (P = 2.35 × 10-8 , OR = 3.55, 95% CI = 2.20-5.74). Our findings provide deeper insight into the genetic contribution to glioma in different populations.

Arbutin exerts anticancer activity against rat C6 glioma cells by inducing apoptosis and inhibiting the inflammatory markers and P13/Akt/mTOR cascade.

Gliomas are a type of brain cancer that occurs in the supporting glial cells of the brain. It is highly malignant and accounts for 80% of brain tumors with high mortality and morbidity. Phytomedicines are potent alternatives for allopathic drugs which cause side effects. They have been used from ancient times by traditional Chinese, Ayurveda, and Siddha medicine. Arubtin is a glycoside phytochemical extracted from plants and belongs to the family of Ericaceae. Arbutin possesses various pharmacological properties such as anti-inflammatory, antioxidant, antitumor, and so on. Hence in the present study, we analyzed the anticancer potency of arbutin against rat C6 glioma cells. Rat C6 glioma cells were procured from American Type Culture Collection and the cells were cultured in Roswell Park Memorial Institute-1640 medium. To assess the cytotoxicity effect of the arbutin against C6 glioma cells, an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide test was performed with different doses from 10 to 60 µM. Arbutin effectively induced apoptosis in the cells and the IC50 dose was obtained at 30 µM. For further studies, we selected the 30 µM IC50 dose and a higher dose of 40 µM. Reactive oxygen species (ROS) generated were analyzed with DCFDA/H2DCFDA stain and the destruction of mitochondrial membrane permeability which is the initiator of apoptosis was analyzed with a cationic stain Rhodamine 123. Dual staining with acridine orange and ethidium bromide was performed to assess the viable and dead cells. Cell adhesion properties of glioma cells were analyzed with Matrigel assay. The apoptotic, inflammatory, and phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling molecules were analyzed with quantitative polymerase chain reaction (qPCR) analysis to confirm the anticancer effect of arbutin. Arbutin generated excessive ROS and disrupted the mitochondrial membrane, which induced apoptosis in cells, it also inhibited the cell adhesion property of C6 glioma cells. qPCR analysis clearly indicates arbutin increases the apoptotic genes and decreased the inflammatory and PI3K/mTOR signaling molecules. Overall, our results authentically confirm that arbutin can be a potent alternative for treating glioma.

Dynamically tunable directional subwavelength beam propagation based on photonic spin Hall effect in graphene-based hyperbolic metamaterials.

Photonic spin Hall effect (PSHE) of type II hyperbolic metamaterials is achieved due to near filed interference, which provides a way to decide the propagation direction of subwavelength beam. In this paper, we propose graphene-based hyperbolic metamaterials (GHMMs), which is composed of the alternating graphene/SiO2 multilayer. The numerical results show that when a dipole emitter is placed at the boundary of the GHMMs, the subwavelength beam with λ/40 full-with half maximum can be excited and propagates along the left or right channel, which is dependent on polarization handedness. In addition, we further demonstrate that the unidirectional propagation angle can be dynamically tuned by changing the external electric field bias applied to graphene.

Durable effects of acupuncture for tension-type headache: A systematic review and meta-analysis.

Background: Acupuncture may be effective in treating tension-type headache (TTH). The durability of its effects after treatment completion remains inconclusive. Methods: We searched multiple databases and references from previous reviews for randomized controlled trials (RCTs) which investigated the effectiveness of acupuncture for TTH. We assessed the methodological quality of RCTs using the Cochrane Risk of Bias 2.0 (RoB 2) tool. Primary outcome was response rate, defined as the proportion of participants who reported at least a 50% reduction in monthly headache days from baseline after completion of treatment. Secondary outcomes included headache days, headache intensity, and analgesic use. Safety outcomes were also evaluated. Results: A total of seven RCTs involving 3,221 participants with frequent episodic and chronic TTH were included. Individuals receiving acupuncture reported a significantly higher response rate versus sham acupuncture (SA) immediately and at 1-6 months after completion of treatment (P<0.05). Compared with SA, post-treatment results of headache days and headache intensity appeared consistent on the whole, showing associations favoring acupuncture. However, no significant reduction in analgesic use was found post-treatment. Acupuncture showed no superiority over physical training or relaxation training in headache days and headache intensity. Moreover, no serious adverse events associated with acupuncture were reported. Conclusion: Limited evidence suggested that acupuncture might provide durable post-treatment effects in the management of frequent episodic and chronic TTH for up to 6 months compared with SA,with no severe treatment-related adverse events reported.

A rare case of primary central nervous system histiocytic sarcoma harboring a novel ARHGAP45::BRAF fusion: a case report and literature review.

INTRODUCTION: Patients with histiocytic sarcoma occurring in the central nervous system (CNS) are rare and have a very poor prognosis. The increased use of molecular diagnostic approaches in solid tumors has brought more opportunities for the diagnosis and treatment of central nervous system histiocytic sarcoma (CNSHS). CASE DESCRIPTION: A 9-year-old girl was admitted to the hospital with pain in her head and neck, as well as vomiting. Imaging scans showed a prominent abnormality in the anterior falciform region, and histopathology revealed the presence of CD68 (+) and CD163 (+) cells, leading to a preliminary diagnosis of primary intracerebral CNSHS. Molecular profiling tests identified a new variant of ARHGAP45::BRAF fusion in this case, which has not been reported in any other tumor. The patient underwent surgical removal of the tumor and will require long-term monitoring. CONCLUSION: The presence of the BRAF point mutation, predominantly BRAF p.V600E, has been documented in prior literature of CNSHS. This is the first case of pediatric histiocytic sarcoma in the anterior falciform region who has a unique ARHGAP45::BRAF fusion. The findings of our study indicate that a broader range of molecular assays should be employed in the diagnosis of CNSHS and opens up new possibilities for the treatment of the patient.

Association between epidermal growth factor gene rs4444903 polymorphism and risk of glioma.

The development of glioma is a complex process which may be influenced by many factors including the epidermal growth factor (EGF) gene polymorphism. Previous studies showed that EGF rs4444903 polymorphism could result in increased risk of tumorigenesis in multiple human cancers, but published data regarding the association between EGF rs4444903 polymorphism and glioma risk were inconsistent. To derive a more precise estimation of the association between EGF rs4444903 polymorphism and glioma risk, we performed a systematic review and meta-analysis of previous published studies. PubMed, Embase, and the Wanfang databases were systematically searched to identify relevant studies. Odds ratios (ORs) and 95 % confidence intervals (95 % CIs) were calculated to assess the strength of the association. Ten published studies with 1,891 glioma cases and 2,836 controls were finally included into the study. Overall, there was a significant association between EGF rs4444903 polymorphism and glioma risk in all four genetic models (the allele model: OR=1.25, 95 % CI 1.15-1.37, P<0.001; the codominant model: OR=1.65, 95 % CI 1.36-1.99, P<0.001; the dominant model: OR=1.27, 95 % CI 1.12-1.44, P<0.001; the recessive model: OR=1.48, 95 % CI 1.25-1.75, P<0.001). Subgroup analyses by ethnicity showed that EGF rs4444903 polymorphism resulted in a higher risk of glioma among both Asians and Caucasians. In conclusion, the results suggest that there is a significant association between EGF rs4444903 polymorphism and glioma risk, and genotypes of EGF rs4444903 mutation contribute to increased host susceptibility to glioma.

Efficacy and safety of acupuncture for hand osteoarthritis: study protocol for a multi-center, randomized, sham-controlled clinical trial.

BACKGROUND: Hand osteoarthritis (OA) is a prevalent disorder in the general population. Patients with hand OA often report symptoms of pain, stiffness, and functional limitations, which cause clinical burden and impact on quality of daily life. However, the efficacy of current therapies for hand OA is limited. Other therapies with better effects and less adverse events are in urgent need. Acupuncture is well known for analgesia and has been proved effective in treating basal thumb joint arthritis. This study aims to clarify the efficacy and safety of acupuncture treatment for clinical symptomatic improvement of hand OA. METHODS: This will be a sham-controlled, randomized, multi-center clinical trial. A total of 340 participants will be recruited and randomly allocated to either traditional acupuncture group or sham acupuncture group. All participants will receive 12 treatment sessions over 4 weeks and 2 follow-up assessments in the following 3 months at week 8 and week 16. The primary outcome will be the proportion of responders at week 5. Secondary outcomes will include visual analog scale, Australian Canadian Osteoarthritis Hand Index, Functional Index for hand OA, the number of symptomatic joints, hand grip strength and pinch strength, global assessment, the World Health Organization Quality of Life abbreviated version and expectations. Safety will be evaluated during the whole process of the trial. All outcomes will be analyzed following the intention-to-treat principle. DISCUSSION: This prospective trial will provide high-quality evidence on evaluating the efficacy and safety of acupuncture treatment for hand OA. Results of this trial might contribute in offering a new option to clinical recommendations. Trial registration ClinicalTrials.gov Identifier: NCT05267093. Registered 23 February 2022.

Efficacy and Safety of Acupuncture for Cyclic Mastalgia: Study Protocol for a Randomized, Sham-Controlled Trial.

Purpose: Cyclic mastalgia is prevalent among women and negatively impairs their daily life and work. There is still a lack of effective therapies for mastalgia, and acupuncture may be a promising method. We design this multicenter randomized trial to evaluate the efficacy and safety of acupuncture on cyclic mastalgia. Study Design and methods: Sixty participants with moderate-to-severe cyclic breast pain (with a duration of 5-21 days and the worst pain scoring 5 points or more on Numerical Rating Scale [NRS]) will be recruited at three hospitals in China. They will be randomly assigned to acupuncture group or sham-acupuncture group at 1:1 ratio to receive 16-session treatment during 3 consecutive menstrual cycles, and follow-up for 6 menstrual cycles after treatment. The primary outcome is the change from baseline in the NRS score on the worst breast pain during the third cycle of treatment period. All statistical tests will be two-sided and P value <0.05 will be considered statistically significant.

The durable effect of acupuncture for episodic migraine: a systematic review and meta-analysis.

Background: Migraine is a common and recurrent type of headache. Avoiding trigger factors is not often successful in reducing headache frequency, duration, and severity. Prophylactic medications may be effective but are limited by strict indications and daily medication intake. This review aimed to investigate the durable effect of acupuncture on episodic migraine. Methods: Seven databases including Medline, Embase, PubMed, etc., were searched for English and Chinese literature from their inception to 23 November 2022. Two independent reviewers screened the retrieved studies and extracted the data. Primary outcomes were monthly migraine days, monthly migraine attacks, and VAS score at 3 months post-treatment. The risk of bias in included studies was assessed using the Cochrane Risk of Bias 2.0 tool. Meta-analysis was conducted where applicable. Results: Fifteen studies were included in this review. Acupuncture reduced the number of migraine attacks (MD -0.68; 95% CI -0.93, -0.43; p < 0.001), the number of days with migraine (MD -0.86; 95% CI -1.18, -0.55; p < 0.001), and VAS score (MD -1.01; 95% CI -1.30, -0.72; p < 0.001) to a greater degree than sham acupuncture at 3 months after treatment. Significant differences in reducing pain intensity of migraine in favor of acupuncture compared with waitlist (MD -1.84; 95% CI -2.31, -1.37; p < 0.001) or flunarizine (MD -2.00; 95% CI -2.35, -1.65; p < 0.001) at 3 months after treatment were found, and the differences reached the minimal clinically important difference (MCID). Conclusion: This review found that the durable effect of acupuncture for episodic migraine lasted at least 3 months after treatment. More high-quality studies with longer follow-up periods in the future are needed to confirm the findings.

CDBA: a novel multi-branch feature fusion model for EEG-based emotion recognition.

EEG-based emotion recognition through artificial intelligence is one of the major areas of biomedical and machine learning, which plays a key role in understanding brain activity and developing decision-making systems. However, the traditional EEG-based emotion recognition is a single feature input mode, which cannot obtain multiple feature information, and cannot meet the requirements of intelligent and high real-time brain computer interface. And because the EEG signal is nonlinear, the traditional methods of time domain or frequency domain are not suitable. In this paper, a CNN-DSC-Bi-LSTM-Attention (CDBA) model based on EEG signals for automatic emotion recognition is presented, which contains three feature-extracted channels. The normalized EEG signals are used as an input, the feature of which is extracted by multi-branching and then concatenated, and each channel feature weight is assigned through the attention mechanism layer. Finally, Softmax was used to classify EEG signals. To evaluate the performance of the proposed CDBA model, experiments were performed on SEED and DREAMER datasets, separately. The validation experimental results show that the proposed CDBA model is effective in classifying EEG emotions. For triple-category (positive, neutral and negative) and four-category (happiness, sadness, fear and neutrality), the classification accuracies were respectively 99.44% and 99.99% on SEED datasets. For five classification (Valence 1-Valence 5) on DREAMER datasets, the accuracy is 84.49%. To further verify and evaluate the model accuracy and credibility, the multi-classification experiments based on ten-fold cross-validation were conducted, the elevation indexes of which are all higher than other models. The results show that the multi-branch feature fusion deep learning model based on attention mechanism has strong fitting and generalization ability and can solve nonlinear modeling problems, so it is an effective emotion recognition method. Therefore, it is helpful to the diagnosis and treatment of nervous system diseases, and it is expected to be applied to emotion-based brain computer interface systems.

Effect of electroacupuncture on symptoms of female pelvic organ prolapse (stage II-III) (EAPOP study): protocol of a randomised controlled trial.

INTRODUCTION: Pelvic organ prolapse (POP) is downward descent of pelvic organs, which causes symptoms of the lower genital, urinary and gastrointestinal tracts, and undermines women's daily activities and quality of life. Although studies indicated that electroacupuncture (EA) may be effective in improving the POP symptoms, evidences were not robust. Therefore, this study aims to conduct a randomised controlled trial (RCT) to evaluate the efficacy and safety of electroacupuncture on relieving symptoms of a POP stage II and III among women. METHODS AND ANALYSIS: A two-arm, multicentre, patient-blind RCT will be conducted to compare EA with sham electroacupuncture (SEA) for treating symptoms of POP stage II and III among women in six tertiary hospitals in China. One hundred and sixty eligible women will be assigned with a 1:1 ratio to have received either EA or SEA for 24 times in 12 weeks and followed-up for 24 weeks. The primary outcome will be the change on the total score of the Pelvic Floor Distress Inventory-short form 20 at week 12 from baseline, and will be analysed by t-test or multiple regression model. Intention-to-treat analysis will be performed for all outcomes, and a p value of less than 0.05 (two-sided testing) will be considered as statistical significance. ETHICS AND DISSEMINATION: The study protocol has been approved by the Medical Ethical Committee of Guang'ammen Hospital (No. 2019-249-KY-01). Patients will be informed about the details of the study and asked to sign consent form before enrolment. The results of this study are expected to be written and published on peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04589715.

Effectiveness of electro-press needle for menopause-associated hot flashes: Protocol of a randomized controlled trial.

BACKGROUND: Hot flashes (HF) are a prevalent symptom associated with menopause affecting up to 85% of women aged 40 to 65 years. Previous studies indicated that acupuncture might relieve the symptom of HF significantly; however, its effectiveness has not been clarified quantitatively. Electro-press needles (EPN) is a novel acupuncture that combines a shallow tiny needle with an electrical transdermal stimulator. Either the needle or the electrical stimulator could function in the treatment. This study aims to evaluate the effectiveness of EPN in comparison with no intervention in relieving HF of perimenopausal and postmenopausal women. METHODS/DESIGN: This study will be a 2-arm randomized waitlist controlled trial. According to the ratio of 1:1 and block randomization, a total of 122 patients with moderate or severe HF will be randomly allocated to either EPN group or waitlist control group. The EPN group will receive 3 sessions of EPN treatment each week in consecutive 6 weeks, 18 sessions in total. The waitlist control group will get no intervention over the first 6 weeks. All the patients will be followed up in the next 24 weeks. The primary outcome will be the percentage of the participants whose 24-hour mean HF is 50% less than the baseline at Week 6. Secondary outcomes will include HF score, HF frequency, HF severity, the Menopause Rating Scale and Menopause-Specific Quality of Life Questionnaire Score. DISCUSSION: This study will evaluate the effectiveness and safety of EPN treatment to alleviate HF symptoms in perimenopausal and postmenopausal women, excluding self-healing factors. The limitations of the trial design are its single-center scope, lack of placebo control and impossible to blind the acupuncturists and patients.Trial registration: This clinical trial has been registered in Clinical Trial Registry (registration number: NCT04995107; date of registration: Aug 6, 2021).

Efficacy and Safety of Electro-Thumbtack Needle Therapy for Patients With Chronic Neck Pain: Protocol for a Randomized, Sham-Controlled Trial.

Background: Chronic neck pain is a prevalent condition adversely impacting patients' wellbeing in both life and work experience. Electro-thumbtack needle (ETN) therapy, combining acupuncture with transcutaneous stimulation, might be one of the effective complementary and alternative medicine (CAM) therapies in treating chronic neck pain, although the evidence is scarce. This study aims to estimate the efficacy and safety of ETN therapy for chronic neck pain. Methods and Analysis: This is a sham-controlled, randomized clinical trial. A total of 180 subjects will be randomly allocated to either the ETN group or the sham ETN group. Treatment will be administrated three times a week for four consecutive weeks, with a 6-month follow-up. The primary outcome measure will be the Numerical Rating Scale for neck pain (NRS-NP) over a period of the 4 weeks. Secondary outcome measures include the Northwick Park Neck Pain Questionnaire (NPQ), Neck Disability Index (NDI), Patient Global Impression of Change (PGIC), patient expectation, and preference assessment. The chi-square test or Fisher's exact test will be used for proportions of participants having clinically meaningful improvement. Analysis of covariance or repeated-measures analysis of variance will be applied to examine changes in the outcome measures from baseline. Discussions: This prospective trial will contribute to evaluating the efficacy and safety of ETN in the treatment of chronic neck pain, with an intermediate-term follow-up. This study will provide further evidence for clinical neck pain management. Ethics and Dissemination: This trial has been approved by the Research Ethical Committee of Guang'anmen Hospital (ethical approval number: 2021-039-KY-01). Recruitment began in March 2022 and will continue until December 2023. Dissemination plans include posters, WeChat, websites, and bulletin boards in hospital and communities. Clinical Trial Registration: This trial is registered at ClinicalTrials.gov (identifier: NCT04981171).

Genetic Variations of CARMN Modulate Glioma Susceptibility and Prognosis in a Chinese Han Population.

Background: This study aimed to evaluate the relationship between CARMN polymorphisms and glioma risk and prognosis in a Chinese Han population. Methods: Seven single nucleotide polymorphisms (SNPs) in CARMN were genotyped among 592 glioma patients and 502 healthy controls. Log-additive models were used for risk assessment by the odds ratios (ORs) and 95% confidence intervals (CIs). Univariate and multivariate Cox regression analysis was applied to calculate Hazard ratios (HRs) and 95% CIs for prognosis assessment. Results: CARMN rs13177623 was a protective factor for glioma susceptibility (OR = 0.78, p = 0.043). In addition, rs13177623, rs11168100, rs12654195 and rs17796757 were associated with the risk of glioma among the subgroup stratified by age or gender. We also found that G rs13177623G rs12654195 haplotype was related to the decreased risk of glioma (OR = 0.61, p = 0.005). Importantly, rs13177623 [overall survival (OS): HR = 0.83, p = 0.047, and progression free survival (PFS): HR = 0.82, p = 0.031], rs12654195 (OS: HR = 0.64, p = 0.005 and PFS: HR = 0.65, p = 0.007) and rs11168100 (OS: HR = 0.71, p = 0.035) were associated with a better prognosis for glioma, especially in grade I-II glioma. In patients with grade III-IV glioma, rs17796757 polymorphism presented an improved OS. Conclusion: Our results firstly reported the contribution of CARMN variants (rs11168100, rs12654195, rs13177623, and rs17796757) to the susceptibility and prognosis of glioma in a Chinese Han population, which provided a novel insight on the relationship between CARMN gene and glioma tumorigenesis.
