Electroacupuncture versus Escitalopram for mild to moderate Post-Stroke Depression: A randomized non-inferiority trial.

Objective: To explore the efficacy of electroacupuncture in treating post-stroke depression (PSD) by modulating the inflammatory response pathway. Methods: One hundred and fifty participants with mild or moderate PSD were randomly divided into 75 cases each in the electroacupuncture group (EA group) and escitalopram group (ESC group). In the EA group, 30 sessions of electroacupuncture were performed on the Baihui (GV 20), Yintang (GV 29), and the ipsilateral Taichong (LR 3) and Hegu (LI 4), simultaneous oral placebo for 40 days. The ESC group received oral escitalopram oxalate tablets 10mg to 20mg for 40 days, plus 30 sessions of sham electroacupuncture. The effectiveness of the treatment was evaluated by the Hamilton Depression Scale (HAMD-17), Self-Depression Scale (SDS), Modified Barthel Index Score (MBI), and the serum levels of IL-1ß, IL-6, IL-10, TNF-α, and INF-γ. Results: There was no statistically significant difference in the baseline data, HAMD-17, SDS, MBI scores, and serum IL-1ß, IL-6, IL-10, TNF-α, and INF-γ levels between the two groups of participants before the intervention (P >0.05). After treatment, HAMD-17 and SDS scores continued to decrease and MBI scores continued to increase in both groups. The differences were statistically significant at the 6th week and baseline, the 10th week and baseline, and the 10th week and the 6th week (all P <0.001). The differences in HAMD-17, SDS, and MBI scores between the two groups at the 6th week were not statistically significant (P=0.110, 0.115, 0.516, respectively); HAMD-17 scores and SDS scores in the EA group were lower than those in the ESC group at the 10th week, and the differences were statistically significant (P=0.002,0.026, respectively). In the 6th week, the serum levels of pro-inflammatory factors such as IL-1ß, IL-6, TNF-α, and INF-γ were significantly lower in both groups compared with the baseline, while the level of anti-inflammatory factor IL-10 was significantly higher. The difference between the pre-and post-intervention intra-group comparisons was statistically significant (P <0.001), and the difference between the inter-group comparisons was not statistically significant (P >0.05). No serious adverse events occurred throughout the trial. Both therapies could safely and effectively improve HAMD-17, SDS, and MBI scores and modulate neuroinflammatory responses in PSD participants. After the treatment was stopped, some parameters were better in the EA group than the ESC group in a short time. Conclusion: Electroacupuncture is an effective, alternative to escitalopram for the treatment of mild-to-moderate PSD. Clinical trial registration: Chinese Clinical Trial Registry (ChiCTR2300072576).

[Acupoint injection combined with Vitalstim electrical stimulation for post-stroke dysphagia:a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy of acupoint injection combined with Vitalstim electrical stimulation for post-stroke dysphagia. METHODS: A total of 98 patients with dysphagia after first stroke were randomized into an acupoint injection group (35 cases, 2 cases dropped off), an electrical stimulation group (31 cases, 3 cases dropped off) and a combination group (32 cases, 3 cases dropped off). Injection of mecobalamin into Tunyan point, Vitalstim electrical stimulation and the combination of injection of mecobalamin into Tunyan point and Vitalstim electrical stimulation were applied respectively in the 3 groups, once a day, 10 times as one course, 2 courses were required. Before and after treatment, the tongue muscle thickness and video fluoroscopic swallowing study (VFSS) score were observed in the 3 groups. RESULTS: After treatment, the tongue muscle thickness was decreased (P<0.05), the VFSS scores were increased (P<0.05) compared with before treatment in the 3 groups, and the variation of tongue muscle thickness and VFSS score in the combination group was greater than the acupoint injection group and the electrical stimulation group (P<0.05). CONCLUSION: Both acupoint injection of mecobalamin and Vitalstim electrical stimulation have therapeutic effect on dysphagia after stroke, and the two have synergistic effect.

Voxelwise meta-analysis of gray matter anomalies in chronic cigarette smokers.

BACKGROUND: Evidence from previous voxel-based morphometry (VBM) studies revealed that widespread brain regions are involved in chronic smoking. However, the spatial localization reported for gray matter (GM) abnormalities is heterogeneous. The aim of the present study was quantitatively to integrate studies on GM abnormalities observed in chronic smokers. METHODS: A systematic search of the PubMed, Web of Knowledge and Science Direct databases from January 1, 2000 to July 31, 2015 was performed to identify eligible whole-brain VBM studies. Comprehensive meta-analyses to investigate regional GM abnormalities in chronic smokers were conducted with the Seed-based d Mapping software package. RESULTS: Eleven studies comprising 686 chronic cigarette smokers and 1024 nonsmokers were included in the meta-analyses. Consistently across studies, the chronic smokers showed a robust GM decrease in the bilateral prefrontal cortex and a GM increase in the right lingual cortex. Moreover, meta-regression demonstrated that smoking years and cigarettes per day were partly correlated with GM anomalies in chronic cigarette smokers. CONCLUSIONS: The convergent findings of this quantitative meta-analysis reveal a characteristic neuroanatomical pattern in chronic smokers. Future longitudinal studies should investigate whether this brain morphometric pattern can serve as a useful target and a prognostic marker for smoking intervention.

Regional gray matter deficits in alcohol dependence: A meta-analysis of voxel-based morphometry studies.

BACKGROUND: Many studies have revealed a widespread pattern of gray matter (GM) atrophy by using voxel-based morphometry (VBM) studies involving the pathophysiology of alcohol dependence. However, the spatial localization of GM abnormalities reported in previous studies is heterogeneous. Here, we aimed to investigate the concurrence across VBM studies to help clarify the structural abnormalities underpinning this condition. METHODS: A systematic search from January, 2000 to November, 2014 was performed to identify VBM studies that compared alcohol dependent patients and healthy controls. A quantitative meta-analysis of whole-brain VBM studies to estimate regional GM abnormalities in alcohol dependent patients was performed using the Anisotropic Effect Size version of the Signed Differential Mapping (AES-SDM) software package. RESULTS: Nine studies consisting of 296 alcohol dependent patients and 359 healthy controls were included in the present meta-analyses. Regional GM atrophy in alcohol dependent patients was found in the prefrontal cortex (including the anterior cingulate cortex), the dorsal striatum/insula, and the posterior cingulate cortex consistently across studies. The results remained largely unchanged in the following jackknife sensitivity analyses. CONCLUSIONS: By conducting the first comprehensive meta-analysis of VBM studies, we identified consistent regional GM atrophy particularly within several neurofunctional networks associated with alcohol dependence. Our study demonstrated a characteristic pattern of GM abnormalities and provided further insights into understanding the underlying nature of alcohol dependence.

OBJECTIVE: We isolated 339 bacillus strains from 72 soil samples all over the country, then purified their antimicrobial compounds and studied the antibacterial activity, to enrich bacillus resources and explore their second metabolites. METHODS: A bacillus strain with strong antibacterial activity was selected by dilution plate and water bath heating from a soil sample from a peanut plantation in Henan Province; this strain was identified according to morphological observation, physiological and biochemical characteristics, and consequences of 16S rRNA homologous analysis. Antibacterial compound from the identified strain, Bacillus amyloliquefaciens X030, was separated and purified by acetone precipitation, Sephadex chromatography, C18 reverse phase column chromatography. Its molecular weight was analyzed by LC-MS/MS. The antibacterial activity was characterized by disc diffusion and plate two-way cultivation. RESULTS: Bacillus amyloliquefaciens was isolated that not only has antibacterial activity against Staphylococcus aureus, Candida albican and Saccharomycetes; but also against Pyriculariaoryzae, Chili pointed cell anthrax, Gloeosporium eriobotryae speg and Phytophthora parasitica. The compound was confirmed as polypeptide. CONCLUSION: Bacillus amyloliquefaciens X030 can produce a polypeptide that inhibits pathogenic bacteria and plant pathogenic fungi.
