[Evaluation of the reporting quality of randomized controlled trials of acupuncture for depression based on CONSORT statement, STRICTA criteria and SHARE checklist].

OBJECTIVE: To evaluate the reporting quality of randomized controlled trials (RCTs) of acupuncture for depression. METHODS: Systematic searches were performed in PubMed, the Cochrane Library, EMbase, CNKI, Wanfang, SinoMed and VIP Database for RCTs of acupuncture in treatment of depression. The search time was from the establishment of database to December 1, 2023, and the language restriction was Chinese and English. The reporting quality of RCTs of acupuncture for depression was evaluated using the CONSORT statement, the international standardization for trial reporting, STRICTA, the international standard for clinical trial interventions of acupuncture, and SHARE, the guideline and checklist for reporting sham acupuncture controls. RESULTS: According to the CONSORT statement items, the items with the reporting rate less than 50% was accounted for 54.05% of all of the items for Chinese articles, and there were 8 and 1 items with a reporting rate of 0% and 100%, respectively. For the English articles, the items with the reporting rate less than 50% was accounted for 35.14% of all of the items, and there were 3 and 7 items with a reporting rate of 0% and 100%, respectively. The reporting rate of 15 items in Chinese and English articles was greater than 50%, e.g. structured abstract, background and purpose. Based on STRICTA criteria, the reporting rate of either Chinese or English articles was relatively high. The items for Chinese articles with the reporting rate less than 50% was accounted for 23.53% of all of the items, and there were 1 and 4 items with a reporting rate of 0% and 100%, respectively. For English articles, the items with the reporting rate less than 50% was accounted for 11.76% of all of the items, and there was 1 item with a reporting rate of either 0% or 100%. In compliance with SHARE checklist, the reporting rate was low for either Chinese or English articles. The items with the reporting rate less than 50% was accounted for 57.89% of all of the items for Chinese articles, and there were 2 and 0 items with a reporting rate of 0% and 100%, respectively. For English articles, the items with the reporting rate less than 50% was accounted for 52.63% of all of the items, and there was 1 item with a reporting rate of 0% and 100%, respectively. CONCLUSION: The overall reporting quality of RCTs of acupuncture for depression is low currently. It is urgent to enhance the reporting of the details on sham acupuncture control especially. It is suggested that RCTs should be reported strictly in compliance with the CONSORT statement, STRICTA criteria, and SHARE checklist in the future.

Effect of Acupuncture on Neurogenic Claudication Among Patients With Degenerative Lumbar Spinal Stenosis : A Randomized Clinical Trial.

BACKGROUND: Acupuncture may improve degenerative lumbar spinal stenosis (DLSS), but evidence is insufficient. OBJECTIVE: To investigate the effect of acupuncture for DLSS. DESIGN: Multicenter randomized clinical trial. (ClinicalTrials.gov: NCT03784729). SETTING: 5 hospitals in China. PARTICIPANTS: Patients with DLSS and predominantly neurogenic claudication pain symptoms. INTERVENTION: 18 sessions of acupuncture or sham acupuncture (SA) over 6 weeks, with 24-week follow-up after treatment. MEASUREMENTS: The primary outcome was change from baseline in the modified Roland-Morris Disability Questionnaire ([RMDQ] score range, 0 to 24; minimal clinically important difference [MCID], 2 to 3). Secondary outcomes were the proportion of participants achieving minimal (30% reduction from baseline) and substantial (50% reduction from baseline) clinically meaningful improvement per the modified RMDQ. RESULTS: A total of 196 participants (98 in each group) were enrolled. The mean modified RMDQ score was 12.6 (95% CI, 11.8 to 13.4) in the acupuncture group and 12.7 (CI, 12.0 to 13.3) in the SA group at baseline, and decreased to 8.1 (CI, 7.1 to 9.1) and 9.5 (CI, 8.6 to 10.4) at 6 weeks, with an adjusted difference in mean change of -1.3 (CI, -2.6 to -0.03; P = 0.044), indicating a 43.3% greater improvement compared with SA. The between-group difference in the proportion of participants achieving minimal and substantial clinically meaningful improvement was 16.0% (CI, 1.6% to 30.4%) and 12.6% (CI, -1.0% to 26.2%) at 6 weeks. Three cases of treatment-related adverse events were reported in the acupuncture group, and 3 were reported in the SA group. All events were mild and transient. LIMITATION: The SA could produce physiologic effects. CONCLUSION: Acupuncture may relieve pain-specific disability among patients with DLSS and predominantly neurogenic claudication pain symptoms, although the difference with SA did not reach MCID. The effects may last 24 weeks after 6-week treatment.

[Effects of Shugan Tiaoshen intradermal needling intervention on attentional networks in subthreshold depression: a randomized controlled trial].

OBJECTIVE: To analyze the effects of Shugan Tiaoshen (regulating liver and harmonizing spirit) intradermal needling protocol on the attentional networks of patients with subthreshold depression using the attention network test (ANT). METHODS: Eighty patients with subthreshold depression were randomly divided into an intradermal needling group (40 cases) and a sham needling group (40 cases, 2 cases dropped out), with an additional 43 healthy subjects as a normal group. The intradermal needling group received intradermal needling treatment, while the sham needling group received sham intradermal needling, with the needle tip not penetrating the skin. The bilateral Xinshu (BL 15), Ganshu (BL 18), Shentang (BL 44) as well as auricular points Xin (CO15) and Gan (CO12) were selected alternately. Treatments were administered twice a week for a total of 6 weeks in the two groups. The patient health questionnaire-9 (PHQ-9) and generalized anxiety disorder (GAD-7) scores were observed before treatment, after 3 weeks of treatment, after treatment, and at 1 month after the end of treatment (follow-up), and the ANT of the two groups of patients with subthreshold depression before and after treatment as well as the normal group of healthy subjects was compared. RESULTS: The PHQ-9 and GAD-7 scores of the patients with subthreshold depression were decreased after 3 weeks of treatment, after treatment, and in follow-up in the two groups (P<0.05), the differences in PHQ-9 and GAD-7 scores before and after treatment were greater in the intradermal needling group than those in the sham needling group (P<0.01). Before treatment, the executive control network reaction time of the subthreshold depression group (the intradermal needling group and the sham needling group) was higher than that of the normal group (P<0.05). Compared before treatment, the executive control network reaction time of the patients in the intradermal needling group and the sham needling group was decreased after treatment (P<0.05), and the alerting network reaction time of the intradermal needling group was increased after treatment (P<0.05); the difference in alerting network reaction time before and after treatment was greater in the intradermal needling group than that of the sham needling group (P<0.01). CONCLUSION: Regulating liver and harmonizing spirit intradermal needling protocol could effectively improve depressive and anxious symptoms in patients with subthreshold depression, and enhance the efficiency of the alerting network.

[Interaction between depression and insomnia under acupuncture treatment: a secondary analysis of a randomized controlled trial].

OBJECTIVE: To explore the interaction between emotional and insomnia symptom improvement in comorbid depression and insomnia patients treated with optimized acupuncture. METHODS: A secondary analysis was conducted on a multicenter randomized controlled trial of acupuncture treatment for comorbid depression and insomnia. One hundred and forty patients with comorbid depression and insomnia were randomly assigned to an optimized acupuncture group (70 cases, 8 cases dropped out) and a conventional acupuncture group (70 cases, 8 cases dropped out). The patients in the conventional acupuncture group were treated with acupuncture at Yintang (GV 24+), Baihui (GV 20), bilateral Hegu (LI 4) and Taichong (LR 3); the patients in the optimized acupuncture group were treated with additional acupuncture at bilateral Lieque (LU 7), Zhaohai (KI 6), and intradermal needling was applied alternately at bilateral Xinshu (BL 15) and Danshu (BL 19), Shenshu (BL 23) and Anmian (Extra). Both groups received treatments twice a week for six weeks. The Hamilton depression scale-24 (HAMD-24) and Pittsburgh sleep quality index (PSQI) scores were observed before and after treatment for both groups. Mediation analysis was used to assess the mesomeric effect of PSQI and HAMD-24 emotional factors, and latent profile analysis categorized patients into subgroups based on HAMD-24 scores, followed by between-group efficacy comparisons. RESULTS: The indirect effect of the optimized acupuncture on improving depression emotions through PSQI was 3.052 (95%CI [1.407, 4.697]), accounting for 77.5% of the total effect. Conversely, the indirect effect of improving PSQI through the optimized protocol on depression emotions was 0.479 (95%CI [0.024, 0.935]), representing 14.8% of the total effect. Latent profile analysis identified 3 categories based on emotional and insomnia symptoms, and statistically significant differences in efficacy favoring the optimized acupuncture protocol over the conventional acupuncture protocol were observed only in the subgroup with relatively mild depression and insomnia symptoms (PSQI: 95%CI [-10.98, -5.44], P<0.001; HAMD-24: 95%CI [-12.31, -3.73], P =0.001). CONCLUSION: The optimized acupuncture protocol primarily improves insomnia symptoms and further improves depression emotions. Its efficacy advantages are more evident in patients with mild symptoms compared with the conventional acupuncture protocol.

Transient induction of actin cytoskeletal remodeling associated with dedifferentiation, proliferation, and redifferentiation stimulates cardiac regeneration.

The formation of new and functional cardiomyocytes requires a 3-step process: dedifferentiation, proliferation, and redifferentiation, but the critical genes required for efficient dedifferentiation, proliferation, and redifferentiation remain unknown. In our study, a circular trajectory using single-nucleus RNA sequencing of the pericentriolar material 1 positive (PCM1+) cardiomyocyte nuclei from hearts 1 and 3 days after surgery-induced myocardial infarction (MI) on postnatal Day 1 was reconstructed and demonstrated that actin remodeling contributed to the dedifferentiation, proliferation, and redifferentiation of cardiomyocytes after injury. We identified four top actin-remodeling regulators, namely Tmsb4x, Tmsb10, Dmd, and Ctnna3, which we collectively referred to as 2D2P. Transiently expressed changes of 2D2P, using a polycistronic non-integrating lentivirus driven by Tnnt2 (cardiac-specific troponin T) promoters (Tnnt2-2D2P-NIL), efficiently induced transiently proliferative activation and actin remodeling in postnatal Day 7 cardiomyocytes and adult hearts. Furthermore, the intramyocardial delivery of Tnnt2-2D2P-NIL resulted in a sustained improvement in cardiac function without ventricular dilatation, thickened septum, or fatal arrhythmia for at least 4 months. In conclusion, this study highlights the importance of actin remodeling in cardiac regeneration and provides a foundation for new gene-cocktail-therapy approaches to improve cardiac repair and treat heart failure using a novel transient and cardiomyocyte-specific viral construct.

Effect of acupuncture and moxibustion on artery elasticity for early carotid atherosclerosis. / é’ˆç¸å¯¹é¢ˆåŠ¨è„‰ç²¥æ ·ç¡¬åŒ–æ—©æœŸæ‚£è€ è¡€ç®¡å¼¹æ€§çš„å½±å“.

OBJECTIVES: To observe the effect of acupuncture and moxibustion on arterial elasticity in patients with early carotid atherosclerosis. METHODS: A total of 62 patients with early carotid atherosclerosis were randomly divided into a blank group (12 cases, 1 cases dropped-off), a sham-acupuncture group (25 cases, 5 cases dropped-off) and an acupuncture group (25 cases, 3 cases dropped-off). Patients in the acupuncture group received acupuncture treatment, including ①acupuncture：Baihui (GV20), Yintang (GV24+), Renying (ST9), Neiguan (PC6), Yanglingquan (GB34)；②moxibustion：Yinqiguiyuan (Zhongwan ［CV12］, Xiawan ［CV10］, Qihai ［CV6］, Guanyuan ［CV4］), Sihua (Geshu ［BL17］, Danshu ［BL19］)；③Intradermal needle：Xinshu (BL15), Danshu (BL19). Patients in the sham acupuncture group received placebo acupuncture, moxibustion, an intradermal needle, and the acupoints were the same as the acupuncture group. The above treatments were performed twice a week for 12 weeks. No intervention was given to the patients in the blank group. Diet and lifestyle education was given to the three groups. The ultrafast pulse wave velocity, including beginning-systolic pulse wave velocity (BS) and end-systolic pulse wave velocity (ES), was observed before treatment and 1, 2, 3 months after treatment in the three groups. The blood lipid level and platelet count (PLT) at each time point were observed. The safety of the treatments was also evaluated. RESULTS: Compared with those before treatment, the BS and ES values of both sides in the acupuncture group decreased at 2 and 3 months after treatment (P<0.05). Compared with the blank group, the bilateral ES of the acupuncture group were decreased at 2 months after treatment (P<0.05), and the bilateral BS and ES were decreased at 3 months (P<0.05). Compared with the sham-acupuncture group, the acupuncture group showed a decrease in left BS and left ES after 3 months of treatment (P<0.05), and the overall decrease on the left side of the acupuncture group was better than that on the right side. There were no significant differences between three groups in the levels of blood lipid and PLT at each time point. No serious adverse safety events occurred in the three groups during the treatment. CONCLUSIONS: Acupuncture and moxibustion therapy can improve arterial elasticity in patients with early carotid atherosclerosis, and it is safe and effective.

Intraoral Acupuncture for Sialorrhea in Stroke Patients: a Study Protocol for a Randomized Controlled Trial.

Importance: Post-stroke sialorrhea (PSS) refers to excessive saliva flowing out the lip border after a stroke. PSS negatively affects patient self-image and social communication and may lead to depression. Limited evidence supports the link between excessive salivation and PSS. No large-scale, strictly controlled randomized controlled trials have shown the effectiveness of acupuncture in treating PSS patients. Objective: We aim to compare the effects of intraoral and sham acupuncture in PSS patients and explore relationships among salivation and drooling severity and frequency and swallowing function in stroke patients. Design: Clinical study protocol, SPIRIT compliant. Setting: Prospective, single-center, randomized, and sham-controlled trial. Population: We will recruit 106 PSS patients to receive 4-week intraoral or sham acupuncture. Additionally, 53 stroke patients without PSS will undergo a conventional 4-week treatment program to compare salivation between PSS and non-PSS patients. Exposures: Intraoral or sham acupuncture. Main Outcomes and Measures: The main evaluation index will be the 3-minute saliva weight (3MSW), comparing changes in 3MSW from baseline to weeks 4 and 8. Secondary assessment indices will include the "Drooling Severity and Frequency Scale" and "Functional Oral Intake Scale." Results: The results from this study will be published in peer-reviewed journals. Conclusion: Comparing effects of intraoral and sham acupuncture in PSS patients, this study may contribute important evidence for future PSS treatment and provide valuable insights into whether salivation issues in stroke patients are attributed to heightened salivary secretion or dysphagia.

Subregions of the fusiform gyrus are differentially involved in the attentional mechanism supporting visual mental imagery in depression.

BACKGROUND: Impaired visual mental imagery is an important symptom of depression and has gradually become an intervention target for cognitive behavioral therapy. METHODS: Our study involved a total of 25 healthy controls (HC) and 23 individuals with moderate depressive symptoms (MD). This study explored the attentional mechanism supporting visual mental imagery impairments in depression using the Vividness of Visual Imagery Questionnaire (VVIQ), attentional network test (ANT), and resting-state functional magnetic resonance imaging (rs-fMRI). The intrinsic activity of attention-related regions relative to those supporting visual mental imagery was identified in depression patients. In addition, a meta-analysis was used to describe the cognitive function related to this intrinsic activity. RESULTS: The global correlation (GCOR) of the right anterior fusiform gyrus (FG) was decreased in depression patients. Attention-related areas were concentrated in the right posterior FG; the anterior and posterior functional connectivity (FC) of the FG was decreased in depression patients. Graph theoretic analysis showed that the degree of the right anterior FG was decreased, the degree of the anterior insula was increased, and the negative connection between these two regions was strengthened in depression patients. In addition, the degree of the right anterior FG, the FC between the subregions of the right FG, and the FC between the right anterior FG and insula were correlated with VVIQ scores; however, this correlation was not significant in depression patients. The meta-analysis suggested that the changes in the anterior FG in depressed patients may stem from difficulties of semantic memory retrieval. CONCLUSION: The changed intrinsic activity of subregions of the FG relative to the semantic memory retrieval may be associated with visual mental imagery impairments in depression.

Perceived stress and brain connectivity in subthreshold depression: Insights from eyes-closed and eyes-open states.

Perceived stress is an acknowledged risk factor for subthreshold depression (StD), and fluctuations in perceived stress are thought to disrupt the harmony of brain networks essential for emotional and cognitive functioning. This study aimed to elucidate the relationship between eye-open (EO) and eye-closed (EC) states, perceived stress, and StD. We recruited 27 individuals with StD and 33 healthy controls, collecting resting state fMRI data under both EC and EO conditions. We combined intrinsic connectivity and seed-based functional connectivity analyses to construct the functional network and explore differences between EC and EO conditions. Graph theory analysis revealed weakened connectivity strength in the right superior frontal gyrus (SFG) and right median cingulate and paracingulate gyrus (MCC) among participants with StD, suggesting an important role for these regions in the stress-related emotions dysregulation. Notably, altered SFG connectivity was observed to significantly relate to perceived stress levels in StD, and the SFG connection emerges as a neural mediator potentially influencing the relationship between perceived stress and StD. These findings highlight the role of SFG and MCC in perceived stress and suggest that understanding EC and EO states in relation to these regions is important in the neurobiological framework of StD. This may offer valuable perspectives for early prevention and intervention strategies in mental health disorders.

Electro-acupuncture inhibits HDAC2 via modulating gut microbiota to ameliorate SNI-induced pain and depression-like behavior in rats.

BACKGROUND: Depression and chronic pain frequent co-occur, exacerbating each other's symptoms and hindering treatment. Emerging studies have highlighted abnormal gut microbiota in both conditions. Previous studies have demonstrated the clinical effectiveness of electro-acupuncture (EA) in managing these conditions, yet the underlying mechanisms remain elusive. METHODS: Spared nerve injury (SNI) was employed to induce chronic pain and depression-like behavior. Rats were randomly assigned to sham SNI (SS), SNI, and EA groups. SNI surgery was performed on all rats, except those in SS group, which underwent sham SNI surgery. Then EA group received 5 weeks of EA treatment. Pain and depression-like behavior were assessed through paw withdrawal threshold, sucrose-preference test, and forced swim test. Gut microbiota composition was analyzed via 16S rDNA sequencing. Brain-Derived Neurotrophic Factor (BDNF) and acetylation-related proteins in the medial prefrontal cortex (mPFC) were evaluated through enzyme-linked immunosorbent assay and western blot. RESULTS: EA treatment significantly ameliorated pain and depression-like behavior. The 16S rDNA sequencing showed EA modulated gut microbiota composition, increased short-chain fatty acids (SCFAs)-producing bacteria, including Akkermansi, Ruminococcaceae and Lachnospiraceae family, particularly Akkermansia. Furthermore, EA increased BDNF, AcH3 and decreased HDAC2 in mPFC. Notably, SCFAs-producing bacteria exhibited a negative correlation with HDAC2 levels. LIMITATIONS: This study exclusively investigated microbiota differences resulting from EA stimulation, without delving into the functional variations brought about by these microbial distinctions. CONCLUSIONS: The therapeutic effects of EA on the comorbidity of chronic pain and depression may involve the modulation of the gut microbiota, resulting in histone acetylation changes and upregulation of BDNF.

Professor FU Wenbin's experience of "acupuncture-moxibustion-consolidation" holistic idea in treatment of laryngeal herpes zoster with vocal cord paralysis. / 符文彬教授整合思维"一针二灸三巩固"模式治疗喉带状疱疹伴声带麻痹的临床经验.

This paper introduces professor FU Wenbin's clinical experience in the treatment of laryngeal herpes zoster with vocal cord paralysis, using the holistic mode of treatment, in which, acupuncture, moxibustion and consolidation regimens are integrated. Regarding the core pathogenesis of the disease, the invaded exogenous toxic heat is transformed into fire that flows to the throat. Soothing liver and releasing heat is the general principle of treatment, guiding the entire process of treatment. For acupuncture regimen, the filiform needling is used and the acupoint prescription is composed of Baihui (GV 20), Yintang (GV 24+), Lianquan (CV 23), the four-gate points (bilateral Hegu [LI 4] and Taichong [LR 3]), the group points for conducting qi back to the primary (Zhongwan [CV 12], Xiawan [CV 10], Qihai [CV 6] and Guanyuan [CV 4]), as well as bilateral Fengchi (GB 20), Wangu (GB 12) and Yifeng (TE 17). Besides, the pricking technique is delivered to the posterior wall of the pharynx for soothing the liver, regulating the spirit, reducing the heat and benefiting the throat. For the moxibustion regimen, moxibustion is applied to Fengchi (GB 20), Feishu (BL 13), the four-flower points (bilateral Geshu [BL 17] and Danshu [BL 19]), Shenshu (BL 23) and Mingmen (GV 4), which nourishes the spleen and stomach and reduces the heat pathogen through the heating action of moxibustion specially. In the stage of consolidation, the bloodletting and cupping technique is used at Xinshu (BL 15), Ganshu (BL 18) and Jianjing (GB 21) to eliminate the liver stagnation and the intradermal needling is delivered to sustain the needling stimulation and consolidate the therapeutic effect.

Toe stimulation improves tactile perception of the genitals.

The human body is represented in a topographic pattern in the primary somatosensory cortex (S1), and genital representation is displaced below the toe representation. However, the relationship between the representation of the genitals and toe in S1 remains unclear. In this study, tactile stimulation was applied to the big toe in healthy subjects to observe changes in tactile acuity in the unstimulated genital area, abdomen, and metacarpal dorsal. Then tactile stimulation was applied to the right abdomen and metacarpal dorsal to observe changes in tactile acuity in bilateral genitals. The results revealed that tactile stimulation of the big toe led to a reduction in the 2-point discrimination threshold (2PDT) not only in the stimulated big toe but also in the bilateral unstimulated genitals, whereas the bilateral abdomen and metacarpal dorsal threshold remained unchanged. On the other hand, tactile stimulation of the abdomen and metacarpal dorsal did not elicit 2-point discrimination threshold changes in the bilateral genitals. Cortical and subcortical mechanisms have been proposed to account for the findings. One explanation involves the intracortical interaction between 2 adjacent representations. Another possible explanation is that the information content of a specific body part is broadly distributed across the S1. Moreover, exploring the links between human behaviors and changes in the cerebral cortex is of significant importance.

Association between metabolites in tryptophan-kynurenine pathway and inflammatory bowel disease: a two-sample Mendelian randomization.

Previous observational studies have suggested an association between tryptophan (TRP)-kynurenine (KYN) pathway and inflammatory bowel disease (IBD). However, whether there is a causal relationship among them remains unclear. Therefore, a two-sample Mendelian randomization (MR) study was conducted to explore the potential causal effects of crucial metabolites in TRP-KYN pathway on IBD and its subtypes. Using summary data from genome-wide association studies, a two-sample MR was employed to evaluate the genetic associations between TRP and KYN as exposures and IBD as an outcome. The inverse variance weighted method was used as the primary MR analysis, with MR-Egger, weighted mode, simple mode, and weighted median methods as complementary analyses. The odds ratios (OR) and 95% confidence intervals (CI) were determined for TRP-IBD (OR 0.739, 95% CI [0.697; 0.783]), TRP-UC (OR 0.875, 95% CI [0.814; 0.942]), TRP-CD (OR 0.685, 95% CI [0.613; 0.765]), KYN-IBD (OR 4.406, 95% CI [2.247; 8.641]), KYN-UC (OR 2.578, 95% CI [1.368; 4.858], and KYN-CD (OR 13.516, 95% CI [4.919; 37.134]). Collectively, the MR analysis demonstrated a significant protective association between TRP and IBD, whereas KYN was identified as a risk factor for IBD.

The novel antibody fusion protein rhNRG1-HER3i promotes heart regeneration by enhancing NRG1-ERBB4 signaling pathway.

Stimulating cardiomyocyte proliferation in the adult heart has emerged as a promising strategy for cardiac regeneration following myocardial infarction (MI). The NRG1-ERBB4 signaling pathway has been implicated in the regulation of cardiomyocyte proliferation. However, the therapeutic potential of recombinant human NRG1 (rhNRG1) has been limited due to the low expression of ERBB4 in adult cardiomyocytes. Here, we investigated whether a fusion protein of rhNRG1 and an ERBB3 inhibitor (rhNRG1-HER3i) could enhance the affinity of NRG1 for ERBB4 and promote adult cardiomyocyte proliferation. In vitro and in vivo experiments were conducted using postnatal day 1 (P1), P7, and adult cardiomyocytes. Western blot analysis was performed to assess the expression and activity of ERBB4. Cardiomyocyte proliferation was evaluated using Ki67 and pH 3 immunostaining, while fibrosis was assessed using Masson staining. Our results indicate that rhNRG1-HER3i, but not rhNRG1, promoted P7 and adult cardiomyocyte proliferation. Furthermore, rhNRG1-HER3i improved cardiac function and reduced cardiac fibrosis in post-MI hearts. Administration of rhNRG1-HER3i inhibited ERBB3 phosphorylation while increasing ERBB4 phosphorylation in adult mouse hearts. Additionally, rhNRG1-HER3i enhanced angiogenesis following MI compared to rhNRG1. In conclusion, our findings suggest that rhNRG1-HER3i is a viable therapeutic approach for promoting adult cardiomyocyte proliferation and treating MI by enhancing NRG1-ERBB4 signaling pathway.

The rapid antidepressant effect of acupuncture on two animal models of depression by inhibiting M1-Ach receptors regulates synaptic plasticity in the prefrontal cortex.

BACKGROUND: It is unclear whether acupuncture has a rapid antidepressant effect and what is the main mechanism. METHODS: In this study, forced swimming stress test (FST) in mice were divided into five groups: control group, acupuncture group, scopolamine group, arecoline group, and acupuncture + arecoline group. Chronic unpredictable mild stress (CUMS) model rats were divided into six groups: naïve (non-CUMS) group, CUMS group, acupuncture group, scopolamine group, arecoline group, and acupuncture + arecoline group. Twenty-four hours after the end of treatment, FST was conducted in mice and rats. The expression of M1-AchR, AMPA receptors (GluR1 and GluR2), BDNF, mTOR, p-mTOR, synapsin I, and PSD95 in the prefrontal cortex was determined by western blot. The spine density of neurons in the prefrontal cortex was detected by golgi staining. RESULTS: The results showed that acupuncture reduced the immobility time of FST in two depression models. Acupuncture inhibited the expression of M1-AchR and promoted the expression of GluR1, GluR2, BDNF, p-mTOR, synapsin I, PSD95, and increased the density of neuron dendritic spine in the prefrontal cortex. CONCLUSIONS: The rapid antidepressant effect of acupuncture may be activating the "glutamate tide" - AMPA receptor activation - BDNF release - mTORC1 pathway activation through inhibiting the expression of M1-AchR in the prefrontal cortex, thereby increasing the expression of synaptic proteins and regulating synaptic plasticity.

Professor FU Wen-bin's experience in treating "five delays and five weaknesses" in children with yang-oriented approach. / 符文彬教授从阳论治小儿"五迟五软"经验概要.

Professor FU Wen-bin, based on the concept of the "yang-oriented approach", identifies "yang deficiency with excess yin" as the underlying pathological mechanism of "five delays and five weaknesses" in children. He recommends a treatment model that included acupuncture, moxibustion, and rehabilitation, integrating various therapeutic methods of acupuncture, refined moxibustion, and auricular point sticking. Specific acupoints along the conception vessel, governor vessel, and bladder meridian, as well as related acupoints with tonifying effects on spleen and kidney, are selected to achieve the therapeutic goal of "promoting yang and nourishing yang simultaneously".

Nanodiamond-Enhanced Nanofiber Separators for High-Energy Lithium-Ion Batteries.

Current lithium-ion battery separators made from polyolefins such as polypropylene and polyethylene generally suffer from low porosity, low wettability, and slow ionic conductivity and tend to perform poorly against heat-triggering reactions that may cause potentially catastrophic issues, such as fire. To overcome these limitations, here we report that a porous composite membrane consisting of poly(vinylidene fluoride-co-hexafluoropropylene) nanofibers functionalized with nanodiamonds (NDs) can realize a thermally resistant, mechanically robust, and ionically conductive separator. We critically reveal the role of NDs in the polymer matrix of the membrane to improve the thermal, mechanical, crystalline, and electrochemical properties of the composites. Taking advantages of these characteristics, the ND-functionalized nanofiber separator enables high-capacity and stable cycling of lithium cells with LiNi0.8Mn0.1Co0.1O2 (NMC811) as the cathode, much superior to those using conventional polyolefin separators in otherwise identical cells.

[Effect of acupuncture combined with low frequency rTMS on comorbid mild-to-moderate depressive disorder and insomnia: a randomized controlled trial].

OBJECTIVE: To observe the impacts of acupuncture on depressive mood and sleep quality in patients with comorbid mild-to-moderate depressive disorder and insomnia, and explore its effect mechanism. METHODS: A total of 60 patients with comorbid mild-to-moderate depressive disorder and insomnia were randomly divided into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 2 cases dropped off). In the observation group, acupuncture and low frequency repeated transcranial magnetic stimulation (rTMS) were combined for the intervention. Acupuncture was applied to Baihui (GV 20), Yintang (GV 24+), Neiguan (PC 6) and Yanglingquan (GB 34), etc., the needles were retained for 30 min; and the intradermal needles were embedded at Xinshu (BL 15) and Danshu (BL 19) for 2 days. After acupuncture, the rTMS was delivered at the right dorsolateral prefrontal cortex (R-DLPFC), with 1 Hz and 80% of movement threshold, lasting 30 min in each treatment. In the control group, the sham-acupuncture was adopted, combined with low frequency rTMS. The acupoint selection and manipulation were the same as the observation group. In the two groups, acupuncture was given once every two days, 3 times weekly; while, rTMS was operated once daily, for consecutive 5 days a week. The duration of treatment consisted of 4 weeks. Hamilton depression scale-17 (HAMD-17) and Pittsburgh sleep quality index (PSQI) scores were observed before and after treatment, as well as 1 month after the treatment completion (follow-up period) separately. Besides, the levels of nerve growth factor (BDNF) and γ-aminobutyric acid (GABA) in the serum were detected before and after treatment in the two groups. RESULTS: After treatment and in follow-up, the HAMD-17 scores were lower than those before treatment in the two groups (P<0.05), and the scores in the observation group were lower than the control group (P<0.05). After treatment, the total scores and the scores of each factor of PSQI were reduced in the two groups in comparison with those before treatment except for the score of sleep efficiency in the control group (P<0.05); the total PSQI score and the scores for sleep quality, sleep latency, sleep efficiency and daytime dysfunction in the observation group were all lower than those in the control group (P<0.05). In the follow-up, except for the scores of sleep duration and sleep efficiency in the control group, the total PSQI score and the scores of all the other factors were reduced compared with those before treatment in the two groups (P<0.05); the total PSQI score and the scores of sleep quality, sleep latency, sleep duration, sleep efficiency and daytime dysfunction in the observation group were lower than the control group (P<0.05). After treatment, the levels of serum BDNF and GABA were increased in comparison with those before treatment in the observation group (P<0.05), and the level of serum BDNF was higher than that in the control group (P<0.05). CONCLUSION: Acupuncture relieves depressive mood and improves sleep quality in patients with comorbid mild-to-moderate depressive disorder and insomnia. The effect mechanism may be related to the regulation of BDNF and GABA levels and the promotion of brain neurological function recovery.

[From the body-mind holism to psychosomatic medicine: theory and practice of acupuncture and moxibustion].

The traditional life concept of "body-mind holism" in Chinese medicine has drawn a special attention with the development of modern psychosomatic medicine. The "body-mind holism" is valuable in the guidance for clinical acupuncture practice, but, it is only remained on the theoretical significance by the medical masters in the past dynasties. In the paper, based on the understanding of Huangdi Neijing (Yellow Emperor's Internal Classic), the similarities and differences are compared between the body-mind theory and psychosomatic medicine. In association with clinical observation, from three aspects, i.e. body-mind pathogenesis, acupoint detection and observing the mind, and body-mind treatment, the guidance of "body-mind holism" is explored for the clinical diagnosis and treatment of acupuncture and moxibustion; the referents of "body" and "mind" are clarified in views of disease, diagnosis and treatment; and the treatment strategies of acupuncture and moxibustion are discussed in the perspective of "body-mind holism".

Acupuncture inhibits autophagy and repairs synapses by activating the mTOR pathway in Parkinson's disease depression model rats.

Acupuncture is a good treatment for depression in Parkinson's disease (DPD), so the possible mechanism of acupuncture in the treatment of DPD was explored in this study. Firstly, observing the behavioral changes of the DPD rat model, the regulation of monoamine neurotransmitters dopamine (DA) and 5-hydroxytryptamine (5-HT) in the midbrain, the change of α-synuclein (α-syn) in the striatum, the efficacy of acupuncture in the treatment of DPD was discussed. Secondly, autophagy inhibitors and activators were selected to judge the effect of acupuncture on autophagy in the DPD rat model. Finally, an mTOR inhibitor was used to observe the effect of acupuncture on the mTOR pathway in the DPD rat model. The results showed that acupuncture could improve the motor and depressive symptoms of DPD model rats, increase the content of DA and 5-HT, and decrease the content of ɑ-syn in the striatum. Acupuncture inhibited the expression of autophagy in the striatum of DPD model rats. At the same time, acupuncture upregulates p-mTOR expression, inhibits autophagy, and promotes synaptic protein expression. Therefore, we concluded that acupuncture might improve the behavior of DPD model rats by activating the mTOR pathway, inhibiting autophagy from removing α-syn and repairing synapses.
