OBJECTIVE: To observe the clinical effect of acupuncture-moxibustion therapy of Daoqi Tongluo (conducting qi and unblocking collateral) on chronic primary tinnitus. METHODS: A total of 32 patients with chronic primary tinnitus were included and treated with the acupuncture-moxibustion therapy of Daoqi Tongluo. This regimen was composed of abdominal acupuncture, body acupuncture, warm needling and posterior-auricular local flashing cupping, Zhongwan (CV12), Guanyuan (CV6) and Yindu (KI9), Tinggong (SI19), Cong'er point, Waiguan (TE5) of the affected side, etc. are selected. The treatment was given once every two days, 3 treatments a week; and one course of intervention was required, with 10 treatments included. Before and after treatment, the scores of tinnitus handicap inventory (THI), tinnitus evaluation questionnaire (TEQ), self-rating scale of sleep (SRSS), self-rating anxiety scale (SAS), and self-rating depression scale (SDS) were observed, and the clinical effect was evaluated. RESULTS: After interventions, the scores of THI, TEQ, SRSS, SAS and SDS were reduced in comparison with those before interventions in the patients (P<0.001, P<0.01, P<0.05), and the total effective rate was 71.9% (23/32). CONCLUSION Acupuncture-moxibustion therapy of Daoqi Tongluo is effective on chronic primary tinnitus and this therapy can alleviate tinnitus degree, improve sleep quality and attenuate the anxious and depressive emotion of the patients.

BACKGROUND: The transcription factor POU2F1 regulates the expression levels of microRNAs in neoplasia. However, the miR-29b1/a cluster modulated by POU2F1 in gastric cancer (GC) remains unknown. METHODS: Gene expression in GC cells was evaluated using reverse-transcription polymerase chain reaction (PCR), western blotting, immunohistochemistry, and RNA in situ hybridization. Co-immunoprecipitation was performed to evaluate protein interactions. Transwell migration and invasion assays were performed to investigate the biological behavior of GC cells. MiR-29b1/a cluster promoter analysis and luciferase activity assay for the 3'-UTR study were performed in GC cells. In vivo tumor metastasis was evaluated in nude mice. RESULTS: POU2F1 is overexpressed in GC cell lines and binds to the miR-29b1/a cluster promoter. POU2F1 is upregulated, whereas mature miR-29b-3p and miR-29a-3p are downregulated in GC tissues. POU2F1 promotes GC metastasis by inhibiting miR-29b-3p or miR-29a-3p expression in vitro and in vivo . Furthermore, PIK3R1 and/or PIK3R3 are direct targets of miR-29b-3p and/or miR-29a-3p , and the ectopic expression of PIK3R1 or PIK3R3 reverses the suppressive effect of mature miR-29b-3p and/or miR-29a-3p on GC cell metastasis and invasion. Additionally, the interaction of PIK3R1 with PIK3R3 promotes migration and invasion, and miR-29b-3p , miR-29a-3p , PIK3R1 , and PIK3R3 regulate migration and invasion via the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway in GC cells. In addition, POU2F1 , PIK3R1 , and PIK3R3 expression levels negatively correlated with miR-29b-3p and miR-29a-3p expression levels in GC tissue samples. CONCLUSIONS The POU2F1 - miR-29b-3p / miR-29a-3p-PIK3R1 / PIK3R1 signaling axis regulates tumor progression and may be a promising therapeutic target for GC.

Arsenic, as a toxic substance that can affect human health, can cause various neurological disorders, including cognitive impairment, when excessive. Relevant epidemiological surveys and animal experimental studies have shown that exposure to arsenic can not only cause intellectual impairment and peripheral neuropathy in humans, but also lead to abnormal behavior in humans and animals. However, so far, the mechanism of arsenic induced damage to the nervous system is still unclear. Peroxisome proliferator activated receptor γ auxiliary activation factor 1α (PGC-1α), as a nuclear transcription coactivator, can interact with transcription factors or other coactivators and plays a role in biological processes such as mitochondrial biogenesis and energy metabolism. PGC-1α, by activating mitochondrial biogenesis, affecting energy metabolism, activating oxidative stress regulatory factors [catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), etc.], mitigates the damage to the central nervous system (CNS), peripheral nervous system (PNS), and blood-brain barrier (BBB) caused by arsenic. This article summarize the research progress of arsenic-induced neurological injury and the mechanism of PGC-1α's role in arsenic-induced neurological injury to provide a theoretical basis for further prevention and treatment of neurological diseases caused by arsenic.

Objective:To summarize the clinical and neurophysiological characteristics of epilepsy with blink inducing.Methods:The patients with epilepsy with blink test positive who received 24 h-video-electroencephalography (24 h-VEEG) monitoring from May 2017 to May 2022 in the Xijing Hospital, the Air Force Military Medical University were enrolled. Their clinical and electrophysiological characteristics were studied and they were followed up to observe their prognosis.Results:A total of 42 patients with epilepsy with blink test positive were collected, 1 of whom was lost to follow-up. The remaining 41 patients included 18 males (44%) and 23 females (56%), whose age was 3 to 12 (8.1±2.6) years. Self-limited epilepsy with centrotemporal spikes (SeLECTS) was diagnosed in 35 patients, self-limited epilepsy with autonomic seizures in 3, and developmental epileptic encephalopathy with spike-and-wave activation in sleep in 3, respectively. The electrical status epilepticus during sleep (ESES) was found in 31 patients (76%), whereas 10 (24%) without ESES. Thirty-two patients experienced 24 h-VEEG monitoring more than twice, and 23 of them were seizure free, of whom blink inducing disappeared in 14 patients and existed in 9 in the last 24 h-VEEG monitoring. Among the 9 patients who were not seizure free, blink inducing disappeared in 3 patients and remained in 6. There was no statistically significant difference between the two groups ( P>0.05). The age of the patients whose blink inducing disappeared in the last 24 h-VEEG monitoring after treatment was (11.3±3.1) years. Meanwhile the age of the patients whose blink inducing remained was (9.1±2.3) years, and the difference between the two groups was statistically significant ( t=2.254, P=0.030). Conclusions:Blink inducing is highly age-dependent and common in self-limited focal epilepsy and developmental epileptic encephalopathy, especially in SeLECTS. Moreover, patients with ESES are more likely to be blink test positive. There was no correlation between blink inducing and seizure outcome.

Objective:To investigate the relationship between the cerebral small vascular disease (CSVD) total burden and the imaging markers and the degree of unilateral middle cerebral artery (MCA) stenosis.Methods:The study was a cross-sectional study. Clinical and imaging data of patients with chronic unilateral MCA stenosis who underwent multimodal MRI from October 2015 to January 2019 in the First Medical Center of PLA General Hospital were retrospectively analyzed. A total of 261 patients were included, 187 males and 74 females. According to the degree of MCA stenosis, the patients were divided into 102 cases in severe stenosis-occlusion group (stenosis degree ≥70%) and 159 cases in mild-moderate stenosis group (stenosis degree <70%). CSVD imaging marker scores (including white matter hyperintensity, perivascular space, cerebral microbleed, and lacune of presumed vascular origin) were assessed according to the ?standards for reporting vascular changes on neuroimaging 1 in the 2 groups, and the CSVD total burden score was calculated. Mann-Whitney U test was used to compare the indicators between the two groups, and the CSVD total burden score and imaging marker scores were ultimately included in a multifactorial binary logistic regression to assess the association of CSVD imaging markers with severe stenosis-occlusion of the MCA after adjusting for vascular risk factors (age, gender, drinking, smoking, hypertension, hyperlipidemia, atrial fibrillation and coronary heart disease). Results:There were significant differences in the CSVD total burden, centrum semiovale perivascular space and lacune of presumed vascular origin score between the mild-to-moderate stenosis group and the severe stenosis-occlusion group (all P<0.05), and none of the differences in the remaining imaging marker scores were statistically significant (all P>0.05). Multivariate binary logistics regression analysis showed CSVD total burden score ( OR=1.300, 95% CI 1.047-1.613, P=0.017), centrum semiovale perivascular space score ( OR=2.099, 95% CI 1.540-2.860, P<0.001) and lacune of presumed vascular origin score ( OR=2.609, 95% CI 1.294-5.261, P=0.007) were independent associated with severe stenosis-occlusion of MCA. Conclusion:The higher CSVD total burden score, centrum semiovale perivascular space score and lacune of presumed vascular origin score are associated with severe stenosis-occlusion of MCA.

Objective:To explore the value of fast susceptibility weighted imaging (SWI) generated by a deep learning model in assessment of acute ischemic stroke (AIS).Methods:From January 2019 to January 2021, 118 AIS patients [75 males and 43 females, aged 23-100 (66±14) years] who underwent MR examination and SWI sequence scanning within 24 h of symptom onset in the First Medical Center of PLA General Hospital were retrospectively analyzed. MATLAB ′s randperm function was used to divide 118 patients into a training set of 96 cases and a test set of 22 cases at a ratio of 8∶2. Fourty-seven AIS patients [38 males and 9 females, aged 16-75 (58±12) years] from one center of a multicenter study were selected to build the external validation set. SWI image and filtered phase image were combined into complex value image as full sampling reference image. Undersampled SWI images were obtained by retrospective undersampling of reference fully sampled images, and the undersampling multiple was five times which could save 80% of the scanning time, then the complex-valued convolutional neural network (ComplexNet) was used to develop reconstruct fast SWI. Interclass correlation coefficient (ICC) or Kappa tests were used to compare the consistency of image quality and the diagnostic consistency for the presence of susceptibility vessel sign (SVS), cerebral microbleeds and asymmetry of cerebral deep medullary veins (DMVs) in AIS patient on fully sampled SWI and fast SWI based on ComplexNet.Results:In test set, score of image quality was 4.5±0.6 for fully sampled SWI image and 4.6±0.7 for fast SWI based on ComplexNet, and coefficient was excellent (ICC=0.86, P<0.05). Full sampling SWI had good agreement with fast SWI based on ComplexNet in detecting SVS (Kappa=0.79, P<0.05), microbleeds (Kappa=0.86, P<0.05), and DMVs asymmetry (Kappa=0.82, P<0.05) in AIS patients. In the external validation set, score of image quality was 4.1±1.0 for fully sampled SWI image and 4.0±0.9 for fast SWI based on ComplexNet, and coefficient was excellent (ICC=0.97, P<0.05). Full sampling SWI had good agreement with fast SWI based on ComplexNet in detecting SVS (Kappa=0.74, P<0.05), microbleeds (Kappa=0.83, P<0.05), and DMVs asymmetry (Kappa=0.74, P<0.05) in AIS patients. Conclusions:Deep learning techniques can significantly accelerate the speed of SWI, and the consistency of image quality and detected AIS signs between fast SWI based on ComplexNet and fully sampled SWI is good. The fast SWI based on ComplexNet can be applied to the radiographic assessment of clinical AIS patients

ObjectiveTo investigate the effects of Huashi Runzao prescription （HRP） on the histopathological injury and function of submandibular gland in naive non-obese diabetic （NOD/Ltj） mouse model of Sjögren's syndrome （SS） and its regulatory effect on aquaporin 5 （AQP5） expression in submandibular gland cells. MethodThe SS model was induced in NOD/Ltj mice. The NOD/Ltj female mice aged nine weeks were selected and randomly assigned into model group，HRP group （7.15 g·kg^-1·d^-1），and hydroxychloroquine （HCQ） group （1.30 g·kg^-1·d^-1）， and female BALB/c mice in the same age were selected and assigned into the normal group， with six mice in each group. Drug intervention lasted eight weeks. The water consumption and salivary flow rate （SFR） of each group were recorded. The pathological staining results of the submandibular gland of mice in each group were observed and scored. AQP5 expression was determined by immunohistochemistry （IHC） and Western blot. ResultCompared with the normal group， the model group showed increased water consumption （P<0.05） and reduced SFR （P<0.05）. Compared with the model group， the HRP group showed decreased water consumption （P<0.05） and increased SFR （P<0.05）， and the HCQ group showed increased SFR （P<0.05）. In terms of histopathological results of the submandibular gland，compared with the normal group，the model group showed increased pathological score， number of lymphocyte infiltration foci，and percentage of lymphatic infiltration area （P<0.05）. Compared with the model group， the HRP group showed reduced pathological scores and number of lymphocyte infiltration foci （P<0.05）， and the HRP group and the HCQ group showed reduced percentage of lymphatic infiltration area（P<0.05）. The results of IHC and Western blot showed that compared with the normal group，the model group showed down-regulated expression level of AQP5 protein （P<0.05）， and compared with the model group and the HCQ group，the HRP group showed up-regulated expression level of AQP5 protein （P<0.05）. ConclusionHRP can improve the secretion function of submandibular gland acinous cells and glandular structure injury in SS model mice， and its mechanism may be related to the up-regulation of AQP5 protein expression level in submandibular gland cells.

ObjectiveTo observe the efficacy and safety of Huashi Runzao prescription for patients with primary Sjögren's syndrome （pSS） of combined dryness and dampness pattern. MethodA total of 105 eligible patients were randomized into the experimental group （65 cases） and control group （40 cases）， and they were respectively treated with Huashi Runzao prescription and hydroxychloroquine for 12 weeks. Visual Analogue Scale （VAS） was employed to assess the symptoms. The symptoms of dryness， fatigue， and pain， European League Against Rheumatism （EULAR） Sjögren's Syndrome Patient Reported Index （ESSPRI）， EULAR Sjögren's syndrome disease activity index （ESSDAI）， and immune inflammatory indicators before and after treatment were compared between the two groups， and adverse reactions were observed. ResultAfter treatment， the ESSPRI score was lower than that before treatment in the experimental groups （P<0.01） and was lower in the experimental group than in the control group （P<0.05）. The VAS scores of dry mouth， dry eyes， overall dryness， fatigue， and pain in the experimental group decreased compared with those before treatment （P<0.01）， and the experimental group had lower VAS scores of dry mouth and overall dryness than the control group （P<0.01）. After treatment， the ESSDAI score of both groups decreased compared with that before treatment （P<0.05， P<0.01）， but there was no significant difference between the groups. After treatment， the level of immunoglobulin M （IgM） decreased （P<0.01） and the level of complement C3 increased （P<0.01） in the experimental group， while the level of complement C3 decreased in the control group （P<0.05）. There was no significant difference in the laboratory indexes between groups. During the treatment， stomachache occurred to one case in the experimental group， which was alleviated after the treatment， and no adverse reaction was observed in the control group. According to the chi-square test， the occurrence of adverse reactions was insignificantly different between the two groups. ConclusionHuashi Runzao prescription can alleviate the symptoms of dryness， fatigue， and pain， and reduce disease activity without associated side effects in pSS patients with combined dampness and dryness pattern.

ObjectiveTo explore the characteristics of tongue manifestations and traditional Chinese medicine （TCM） syndromes in patients with primary Sjogren's syndrome （pSS） of different time. MethodpSS patients who visited TCM Department of Rheumatism in China-Japan Friendship Hospital from December 2018 to October 2021 were included and grouped according to the disease courses （short<5 years， medium 5-10 years， long > 10 years）. Chi-square test was used for comparison between three groups and Bonferroni method for multiple comparisons. In the pairwise comparison， P<0.017 indicated significant difference. Chi-square test was performed on the syndrome and specific tongue manifestations with inter-group differences to analyze the trend of tongue manifestations and TCM syndromes over time （interval： two years）. ResultA total of 193 pSS patients were enrolled， with 85 （44.0%） of short disease course， 69 （35.8%） of medium disease course， and 39 （20.2%） of long disease course. The common tongue manifestations were crimson tongue， fissured tongue， thin tongue， lack of fluid， and dry coating， which showed no significant difference among the three groups. Higher proportion of patients with light red tongue was observed in the group with short disease course than in group with medium disease course （χ²=6.407， P<0.017）. Higher proportions of patients with thick coating （χ²=6.784， P<0.017） and phlegm-dampness syndrome （χ²=11.545， P<0.017） and lower proportion of patients with Qi deficiency syndrome （χ²=12.706， P<0.017） were found in the group with short disease course than in the group with long disease course. Patients with medium （χ²=6.358， P<0.017） and long （χ²=8.279， P<0.017） disease course tended to have exfoliated coating compared with those with short disease course， and the proportion of patients with exfoliated coating rose and the proportion of patients with thick greasy coating decreased over time （P_trend<0.05）. In addition， the proportion of patients with phlegm-dampness syndrome decreased and that with Qi deficiency syndrome increased over time （P_trend<0.05）. ConclusionIn the early stage， patients with pSS often show both dryness and dampness， as manifested by the thick greasy coating and phlegm-dampness syndrome. In the medium and late stage， patients often have Qi-Yin deficiency， as evidenced by exfoliated coating and Qi deficiency. In the clinical practice， medicines should be prescribed based on tongue manifestations and TCM syndrome of patients.

ObjectiveTo summarize the characteristics of traditional Chinese medicine （TCM） syndrome in primary Sjögren's syndrome （pSS） patients with interstitial lung disease （ILD） and to explore associated factors. MethodA survey was conducted and pSS patients who were treated in TCM department of rheumatism at China-Japan Friendship Hospital from December 2018 to April 2022 were included. Tongue manifestations and syndromes of patients were recorded. pSS patients with ILD were classified into the pSS-ILD group and those without the ILD were included in the pSS-non-ILD group. The tongue manifestations， syndromes， and laboratory indexes were compared between the two groups， and logistic regression was used to explore the factors associated with pSS-ILD. ResultA total of 200 pSS patients were included， with 186 （93.0%） females， median age of 57 years， and median disease course of 60 months， of which 44 （22%） had pSS-ILD. In terms of tongue manifestations， pSS-ILD patients generally had dark/purple/stasis tongue， fissured tongue， and tongue with little fluid， thick coating， yellow coating， and greasy coating. The proportion patients with yellow coating was higher in pSS-ILD group than in the pSS-non-ILD group （χ²=4.799，P<0.05）. In terms of syndrome， more than 40% of pSS-ILD patients had Qi deficiency， Yin deficiency， phlegm-dampness， Qi stagnation， and/or blood stasis syndrome. As for Yin deficiency， liver-kidney Yin deficiency syndrome ranked the first. For Qi deficiency， lung Qi deficiency syndrome was most commonly seen. The proportion of patients with lung Qi deficiency was higher in the pSS-ILD group than in the pSS-non-ILD group （χ²=18.667，P<0.01）. As to laboratory indexes， compared with the pSS-non-ILD group， pSS-ILD group had high proportion of anti-SSA-positive patients （P<0.05） and high levels of C-reactive protein （CRP） （P<0.01）， complement C3 （χ²=4.332，P<0.05）， and complement C4 （P<0.05）. Logistic regression analysis showed that pSS with ILD was positively associated with lung Qi deficiency ［odds ratio （OR）=6.079， 95% confidence interval （CI） 2.585-14.298， P<0.01）］ and yellow coating （OR=5.260， 95% CI 1.337-20.692， P<0.05） and negatively associated with low C4 （OR=0.199， 95% CI 0.070-0.564， P<0.01）. ConclusionAbout 22% of pSS patients had ILD， and patients with pSS-ILD generally have Qi deficiency， Yin deficiency， phlegm-dampness， Qi stagnation， and/or blood stasis syndrome. Yellow coating， lung Qi deficiency and C4 level are factors associated with pSS combined with ILD.
