ObjectiveTo observe the clinical efficacy of acupuncture combined with bloodletting and cupping in the treatment of chronic spontaneous urticaria(CSU) and to explore its potential mechanisms of action. MethodsSeventy CSU patients were randomly divided into loratadine group and acupuncture + bloodletting group, with 35 patients in each group. The loratadine group received oral loratadine tablets, 10 mg once daily in the evening. The acupuncture + bloodletting group received acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6), Xuehai (SP 10), Quchi (LI 11), Hegu (LI 4), Taichong (LR 3), Baihui (GV 20), and Shenting (GV 24), once daily,along with bloodletting and cupping at Dazhui (GV 14) and Geshu (BL 17), every other day. Both groups were treated for 4 weeks. The 7-day urticaria activity score(UAS7) was assessed before and after the treatment, and levels of serum immunoglobulin E (IgE), interleukin-4 (IL-4), interleukin-5 (IL-5), eosinophil cationic protein (ECP), plasma tissue factor (TF), activated factor Ⅶ (FⅦa), prothrombin fragment 1+2 (F1+2), D-dimer (D-D) and complement component 5a (C5a) were detected. ResultsA total of 65 patients were included in the final analysis, 32 in the loratadine group and 33 in the acupuncture + bloodletting group. Before treatment, there was no significant difference in UAS7 score, serum IgE, IL-4, IL-5, ECP levels, or plasma TF, FⅦa, F1+2, D-D, C5a levels between groups (P> 0.05). After treatment, both groups showed significant reductions in UAS7 score, serum IgE, IL-4, IL-5, and plasma TF, FⅦa, F1+2, D-D, and C5a levels compared to those before treatment (P<0.01). However, after treatment, there was no significant difference in UAS7 score and serum ECP, IgE, IL-4, IL-5 levels between groups (P>0.05). The acupuncture + bloodletting group showed lower plasma TF, FⅦa, F1+2, D-D and C5a levels compared to the loratadine group (P<0.05 or P<0.01). ConclusionAcupuncture combined with bloodletting and cupping can effectively improve the skin symptoms of CSU patients and reduce the levels of inflammatory factors. The potential mechanism of action may involve the regulation of the coagulation-complement-mast cell activation axis, thereby inhibiting mast cell degranulation.

ObjectiveTo explore the possible mechanisms of Shujin Jiannao Formula (舒筋健脑方) for cerebral palsy. MethodsThirty 7-day-old SD rats were randomly divided into normal group, model group, and Shujin Jiannao Formula group, with 10 rats in each group. The model group and Shujin Jiannao Formula group established a cerebral palsy model by the classic Rice-Vannucci method. After successful modeling, rats in Shujin Jiannao Formula group were given Shujin Jiannao Formula 16 g/(kg·d) by gavage, while the normal group and model group were given normal saline 10 ml/(kg·d) by gavage once a day. After one week of intervention, the rats' body weight was measured, and Zea-Longa scores, the righting reflex test, and the hindlimb suspension test were conducted for assessment; hematoxylin-eosin (HE) staining and Nissl staining were used to observe pathological changes in brain tissue, and the number of Nissl-positive neurons was counted; enzyme-linked immunosorbent assay (ELISA) was employed to measure levels of inflammatory cytokines in the brain tissue, specifically interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α); immunofluorescence was used to detect the expression levels of neurofilament protein 200 (NF200) and myelin basic protein (MBP) in brain tissue; Western Blot analysis was conducted to determine the protein levels of phosphoinositide 3-kinase (PI3K), protein kinase B (Akt/PKB/Rac), and mammalian target of rapamycin (mTOR) in brain tissue. ResultsCompared with the normal group, rats in the model group showed significantly higher Zea-Longa scores and lower scores in the hindlimb suspension test (P<0.01); pathological findings revealed loose structure in the cerebral cortex, hippocampal atrophy, and neuronal damage in brain tissue. Levels of IL-1β and TNF-α elevated, and the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region reduced, and immunofluorescence intensity of NF200 and MBP, as well as protein expression levels of PI3K and mTOR, significantly decreased (P<0.05 or P<0.01). Compared with the model group, rats in Shujin Jiannao Formula group showed decreased Zea-Longa scores and increased hindlimb suspension test scores (P<0.05); pathological damage in brain tissue alleviated, levels of IL-1β and TNF-α reduced, the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region increased, and the immunofluorescence intensity of NF200 and MBP, as well as the protein levels of PI3K and mTOR, significantly elevated (P<0.05 or P<0.01). There were no statistically significant differences among the groups in body weight, body-turning time, or AKT protein levels in brain tissue (P>0.05). ConclusionShujin Jiannao Formula can improve the neurological function of rats with cerebral palsy, exert neurorestorative effects, and its mechanism of action may be related to the reduction of inflammatory response in brain tissue and the activation of the PI3K/AKT/mTOR signaling pathway.

Hearing loss is one of the most prevalent sensory disorders affecting the human nervous system. Liquid-liquid phase separation (LLPS) is a physiological process that facilitates the reversible and dynamic assembly of biomolecular condensates. Increasing evidence suggests that LLPS plays a significant role in the pathogenesis of hereditary hearing loss. Nevertheless, there is a conspicuous lack of systematic investigations exploring the impact of LLPS abnormalities on the etiology of hereditary hearing loss. In this review, we examine the mechanisms by which dysfunctions in LLPS contribute to hereditary hearing loss, specifically focusing on its effects on mechanoelectrical transduction in hair bundles, transcriptional regulation, post-transcriptional modifications, the actin cytoskeleton, ion homeostasis within the inner ear, and energy and redox homeostasis. Furthermore, we evaluate the considerable potential of targeting LLPS as a therapeutic approach for hearing loss and propose innovative perspectives on LLPS that may guide future research initiatives in the field of auditory disorders.

Objective To investigate the changes in distribution of Oncomelania hupensis snails in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023, so as to provide insights into formulation of O. hupensis snail surveillance programs. Methods The reports on O. hupensis snail surveillance in Songjiang District, Shanghai Municipality from 2009 to 2023 were collected, and the snail surveillance data in forestlands were extracted. The trends in the proportion of areas with snails in forestlands in total areas with snails, occurrence of frames with living snails and density of living snails were evaluated using a Joinpoint regression model in Songjiang District from 2009 to 2023, and the annual percent change (APC) and average annual percent change (AAPC). Results A total of 40 sites with snails were found in forestlands in 14 administrative villages of 4 townships, Songjiang District, Shanghai Municipality from 2009 to 2023. A total of 39 065 frames were surveyed for snails in settings covering an area of 609 600 m2, and there were 6 084 frames with snails, covering 151 250 m2 snail habitats. A total of 22 210 snails were captured, with the highest density of 260.00 snails/0.1 m2, and 6 262 snails were dissected, with no Schistosoma japonicum infection identified in snails. The proportion of areas with snails in forestlands in total areas with snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023 (APC = AAPC = 24.9%, P > 0.05); however, there were no turning points in the trend curve, with the highest proportion seen in 2009 (53.81%), the lowest in 2011 and 2023 (both 0) and a mean proportion of 24.81%. The occurrence of frames with living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 41.5%, P > 0.05); however, there were no turning points in the trend curve, with the highest occurrence in 2009 (53.81%), the lowest in 2011 and 2013 (both 0), and the mean occurrence of 15.57%. In addition, the density of living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 55.0%, P > 0.05); however, there were no turning points in the trend curve, with the highest density in 2023 (0.96 snails/0.1 m2), the lowest in 2011 and 2013 (both 0), and a mean density of 0.57 snails/0.1 m2. Conclusions The difficulty in O. hupensis snail control and risk of imported snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality over years from 2009 to 2023. Supervision and assessment prior to seedling transplantation and intensified surveillance post-transplantation are recommended to reduce the risk of O. hupensis snail importation and spread.

ObjectiveTo analyze the monitoring results and trends of Oncomelania in Songjiang District of Shanghai from 2007 to 2023, and to provide reference for future monitoring work. MethodsThe data of snail monitoring in Songjiang District from 2007 to 2023 were collected, including the location of snail spots, the number of survey frames, the area with snails, the number of frames with snails, the total number of snails, etc. The density of living snails and the occurrence rate of living snail frames were calculated. ResultsFrom 2007 to 2023, a total of 158 snail spots were found in 22 administrative villages in 4 towns in Songjiang District, including 131 emerging snail habitats (82.91%) and 27 reemerging snail habitats (17.09%). The total snail area was 175 980 m2, the number of snail frames was 10 061, and 33 302 snails were captured. The highest density was 260/0.11 m2, and 15 662 snails were dissected. No positive snails were found. The average density of living snails was 0.60/0.11 m2 and the average occurrence rate of living snail frames was 17.99%. The snail areas in different areas were Yexie Town 126 000 m2 (71.60%), Maogang Town 26 470 m2 (15.04%), Xinbang Town 17 040 m2 (9.68%), and Shihudang Town 6 470 m2 (3.68%). The average density of living snails in different areas was 0.89/0.11 m2 in Yexie Town, 0.65/0.11 m2 in Maogang Town, 0.26/0.11 m2 in Shihudang Town and 0.24/0.11 m2 in Xinbang Town. The snail areas of different snail habitats were as follows: woodland 151 250 m2(85.95%), river 13 810 m2(7.85%), ditch 6 910 m2(3.93%), farmland 4 010 m2(2.28%). The average density of living snails in different snail habitats: ditch 1.01/0.11 m2, beach 0.86/0.11 m2, woodland 0.57/0.11 m2, river 0.40/0.11 m2. The occurrence rate of living snail frames in different regions and different snail environment types showed a downward trend and the difference was statistically significant. ConclusionAlthough the snail monitoring indicators such as snail area, average living snail density and average living snail frame occurrence rate in Songjiang District are still at its historically low level, the average living snail density and average living snail frame occurrence rate are still high compared with other regions or the national average. We should focus on the upper reaches and tributaries of the Huangpu River, especially the key areas of seedling transplantation, and strengthen monitoring and supervision to reduce the risk of snail input.

Objective:To investigate the correlation between 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 3 (PFKFB3) and the inflammatory activation of polymorphonuclear myeloid-derived suppressor cell (PMN-MDSC) in acute myocardial infarction (AMI), and to evaluate the effect of intervention targeting PFKFB3 on the inflammatory activation of PMN-MDSC during AMI.Methods:① Clinical trial section: a observational study was conducted. The patients with acute coronary syndrome (ACS) admitted to Zhenjiang Fourth People's Hospital were enrolled, and they were divided into AMI group and non-AMI group according to clinical diagnosis. The peripheral venous blood of the two groups was collected to detect the proportion of PMN-MDSC, and the expression of PFKFB3 gene in mononuclear cells was detected by real-time quantitative polymerase chain reaction (RT-qPCR). ② Basic experiment section: a total of 30 male C57 mice (aged 6-8 weeks) were divided into normal control group ( n = 5), Sham group ( n = 5), AMI model group ( n = 10) and PFKFB3 inhibitor PKF-15 intervention group ( n = 10) according to random number table method. The AMI model of mice was reproduced by left anterior descending coronary artery (LADCA) ligation, and the mice in the Sham group did not attach the artery after thoracotomy. The PKF-15 intervention group was intraperitoneally injected with PKF-15 (20 μg/g) at the same time of LADCA ligation. Normal control mice did not receive any treatment. Peripheral venous blood and myocardial tissue of mice were collected 24 hours after modeling. Both the circulating PMN-MDSC ratio and the infiltration of PMN-MDSC in myocardial tissue were detected. After staining with hematoxylin-eosin (HE), the degree of inflammatory damage in mouse myocardial tissue was observed under light microscopy. PMN-MDSC were isolated from mice with flow cytometry, and the gene expressions of PFKFB3 and inflammatory factors were measured by RT-qPCR. Results:① Clinical trial section: the circulating PMN-MDSC ratio of patients in the AMI group ( n = 25) was significantly higher than that in the non-AMI group [ n = 20; (8.53±0.96)% vs. (1.13±0.39)%, P < 0.01], and PFKFB3 gene expression in the peripheral blood mononuclear cells was also increased (2 -ΔΔCt: 1.18±0.19 vs. 0.96±0.16, P < 0.01). Pearson correlation analysis showed that circulating PMN-MDSC ratio was positively correlated with PFKFB3 gene expression in mononuclear cells in AMI patients ( r = 0.608, P = 0.001). ② Basic experimental section: the circulating PMN-MDSC ratio and the infiltration of PMN-MDSC in myocardial tissue of AMI mice were significantly higher than those in the normal control group and Sham group. PFK-15 intervention could reduce the ratio of PMN-MDSC in the peripheral blood and myocardial tissue of AMI mice [(26.33±5.27)% vs. (75.12±5.02)% in peripheral blood, (20.87±2.97)% vs. (35.28±4.36)% in myocardial tissue, both P < 0.01]. Under light microscopy, the myocardial cells in the AMI modal group were disordered and a large number of inflammatory cells infiltrated. PFK-15 intervention could maintain a normal arrangement of cardiomyocytes and reduce the infiltration of inflammatory cells. The gene expression levels of PFKFB3 in the peripheral blood and myocardial tissue as well as the inflammatory factors in the myocardial tissue of AMI mice were significantly higher than those in the normal control group and Sham group. PKF-15 intervention could effectively reduce the gene expression levels of PFKFB3 in the peripheral blood and myocardial tissue as well as the inflammatory factors in the myocardial tissue of AMI mice [PFKFB3 mRNA (2 -ΔΔCt): 1.01±0.09 vs. 1.40±0.12 in peripheral blood, 0.95±0.09 vs. 1.47±0.10 in myocardial tissue; myocardial tissue tumor necrosis factor-α (TNF-α) mRNA (2 -ΔΔCt) was 14.55±3.99 vs. 29.66±3.90, interleukin-1β (IL-1β) mRNA (2 -ΔΔCt) was 8.72±1.35 vs. 18.53±2.43, IL-6 mRNA (2 -ΔΔCt) was 11.87±2.97 vs. 19.82±4.32, all P < 0.01]. Conclusions:The activation of PFKFB3 is closely related to the inflammatory activation of PMN-MDSC during AMI. Inhibition of PFKFB3 activity can inhibit the inflammatory activation of PMN-MDSC and reduce myocardial inflammatory injury.

Objective:To investigate the consistency of myocardial extracellular volume between systole and diastole using dual-layer detector spectral CT.Methods:This was a cross-sectional study. Thirty-five patients who underwent cardiac spectral CT examination in West China Hospital of Sichuan University from April 2022 to December 2022 were retrospectively collected. Hematocrit was collected within 3 days before the CT scan. The delayed phases holographic spectral images in systole (45%) and diastole (75%) were obtained using dual-layer spectral CT. CT data were processed using a spectral post-processing workstation, and the extracellular volume (ECV) based on iodine density images, referred as CT-ECV, in systolic and diastolic phases were calculated, respectively. According to the American Heart Association′s 16-segment model of left ventricular, the standard short-axis images were constructed, and the myocardium was standardized into 16 segments at the basal, mid-cavity, and apical levels of the left ventricle. Two radiologists performed a subjective evaluation in the image quality of the CT-ECV images of the whole heart and the three sections in systole and diastole using a "five-point" scale. The ECV of the 16 segments and the whole heart in systole and diastole was calculated. The consistency of subjective evaluations between systole and diastole was assessed using Kappa statistics. Wilcoxon signed-rank tests were used to compare the differences in scores between systole and diastole. Paired sample t-test was used to compare the differences in CT-ECV scores between systole and diastole. The intraclass correlation coefficient was used to test the intra-and inter-observer consistency of CT-ECV measurements between two radiologists. P<0.05 was statistically significant. Results:There was good agreement between the two radiologists on subjective scores of CT-ECV image quality between systole and diastole ( Kappa>0.80), and there was no statistical difference in image quality among the basal, mid-cavity, and apical levels of the left ventricle and whole heart between systole and diastole ( P>0.05). The systolic and diastolic CT-ECV for the entire heart obtained through the delay phase were (33.29±3.46)% and (33.50±3.39)%, respectively, with no statistically significant difference ( t=-0.78, P=0.442). CT-ECV in systole and diastole were (34.15±3.94)% and (35.30±3.99)% for segment 8, (34.03±3.76)% and (35.46±3.74)% for segment 9, and (33.98±3.32)% and (35.05±3.98)% for segment 14, respectively. The mean values of the systolic CT-ECV of segments 8, 9 and 14 were significantly lower than those of diastolic CT-ECV ( t=-2.65, -3.26, -2.42, P=0.012, 0.003, 0.022, respectively). The ICCs for CT-ECV measurements of 16 segments by the two radiologists were greater than 0.90 in both systolic and diastolic, indicating good agreement. Conclusions:There is no significant difference in whole heart CT-ECV values between systolic and diastolic myocardial ECV based on dual-layer spectral CT. However, minor differences (less than 2%) are found between systolic and diastolic myocardial CT-ECV for some segments. Myocardial CT-ECV measurement should be performed on the same segment during the same phase to obtain stable and accurate ECV values.
