ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ （AngⅡ） and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment， AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h， and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 （CCK-8） to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the content of B-type natriuretic peptide （BNP） in cell culture supernatant， and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently， the experiment was divided into a blank group （20% blank serum）， a model group （20% blank serum + 5×10^-5 mol·L^-1 AngⅡ）， low-， medium-， and high-dose （5%， 10% and 20%） serum containing Zhenwutang groups， an autophagy inhibitor group （1×10^-4 mol·L^-1 3-MA）， and autophagy inducer group （1×10^-7 mol·L^-1 rapamycin）. The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe （Lyso Tracker） and mitochondrial probe （Mito Tracker） co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect Caspase-3， Caspase-9， B-cell lymphoma 2 （Bcl-2）， Bcl-2-related X protein （Bax）， and cytochrome C （Cyt C） in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase （Parkin）， phosphatase and tensin homolog （PTEN）-induced kinase 1 （PINK1）， and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3， cleaved Caspase-9， Bax， Bcl-2， and Cyt C in apoptosis-related pathways， phosphorylated ubiquitin ligase （p-Parkin）， phosphorylated PTEN-induced kinase 1 （p-PINK1）， p62， and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways， and the change of microtubule-associated protein 1 light chain 3 （LC3） Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10^-5 mol·L^-1， the cell activity was the lowest， and there was no cytotoxicity. At this concentration， the surface area of cardiomyocytes was significantly increased （P<0.01）， and the content of BNP in the supernatant of culture medium was significantly increased （P<0.05）. Therefore， AngⅡ with a concentration of 5×10^-5 mol·L^-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group， the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate （P<0.01） and significantly decreased mitochondrial membrane potential （P<0.01）. The results of immunofluorescence co-localization showed that compared with the blank group， the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group， the relative mRNA expression of Bax， Caspase-3， Caspase-9， Cyt C， and p62 in the model group was significantly up-regulated （P<0.01）， while the relative mRNA expression of Bcl-2， Parkin， and PINK1 was significantly down-regulated （P<0.01）. In addition， the relative protein expression of Bax， cleaved Caspase-3， cleaved Caspase-9， Cyt C， and p62 was significantly up-regulated （P<0.01）. The LC3Ⅱ/Ⅰ was significantly decreased， and the relative protein expression of Bcl-2， p-Parkin， p-PINK1， and Beclin1 was significantly down-regulated （P<0.01）. Compared with the model group， the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate （P<0.01）， and the decrease ratio of mitochondrial membrane potential is significantly lowered （P<0.01） in a dose-dependent manner. Additionally， both red and green fluorescence spots became more in these groups. In the 3-MA group， the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax， Caspase-3， Caspase-9， Cyt C， and p62 was significantly down-regulated （P<0.05， P<0.01）， while that of Bcl-2， Parkin， and PINK1 was significantly up-regulated （P<0.01）. In the serum containing Zhenwutang groups， the relative protein expression levels of Bax， cleaved Caspase-3， cleaved Caspase-9， Cyt C， and p62 were significantly down-regulated （P<0.05，P<0.01）. The LC3Ⅱ/Ⅰ was significantly increased， and the relative protein expression levels of Bcl-2， p-Parkin， p-PINK1， and Beclin1 were significantly up-regulated （P<0.01）. ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.

Purpose To explore the influence of thrombolysis therapy before percutaneous coronary intervention(PCI)on long-term left ventricular global and regional function in ST segment elevation myocardial infarction(STEMI)patients by cardiac magnetic resonance(CMR).Materials and Methods A retrospective analysis was conducted on 67 STEMI patients who were enrolled in a prospective study from November 2021 to August 2022 in the First Affiliated Hospital with Nanjing Medical University,the First People's Hospital of Lianyungang,the Affiliated Hospital of Jiangnan University,Changzhou No.2 People's Hospital and Huai'an Second People's Hospital and underwent CMR examination one year later.STEMI patients were divided into thrombolysis group and non-thrombolysis group according to whether a single half-dose of 5 mg recombinant staphylokinase(r-SAK)was given within two hours before the first medical contact and PCI.Based on CMR cine images,the traditional left ventricular function,global and segmental functional parameters were measured,and the differences between the two groups were compared.According to the degree of late gadolinium enhancement involvement,myocardial segments were divided into the following four types:transmural infarcted segments,non-transmural infarcted segments,locally infarcted segments,and non-infarcted segments.The parameters of the two groups were compared across these different segments.Results At the patient level,the cardiac index,left ventricular wall thickening and left ventricular wall motion in r-SAK thrombolysis group were higher than those in non-thrombolysis group(t/Z=-2.426,-4.307,-2.735,all P<0.05).At the segment level,compared with non-thrombolysis group,patients received r-SAK before primary PCI showed greater segmental radial strain in non-transmural infarcted segments(Z=-2.117,P=0.034);larger segmental wall motion in locally infarcted segments(Z=-2.235,P=0.025),and better segmental circumference strain in the non-infarcted segments(Z=-3.869,P<0.001).Conclusion The thrombolytic therapy before PCI in STEMI patients retain better long-term left ventricular global and regional function evaluating by CMR.

Objective To investigate the effects of different administration times on the efficacy and safety of subcutaneous immunotherapy using dual mite extracts in patients with allergic rhinitis(AR).Methods This study was designed as a retrospective cohort analysis.Thirty-nine mite-sensitized AR patients who completed three years of standardized dual-mite subcutaneous immunotherapy(SCIT)were included.Based on self-selected and consistently maintained injection schedules,patients were non-randomly assigned to either a morning dosing group(MD group,8:00-12:00,n=19)or an afternoon dosing group(AD group,14:00-18:00,n=20),with further subgroup stratification conducted at 2-hour intervals.Nasal and ocular symptoms were evaluated before and after treatment using the visual analog scale(VAS),and all adverse reactions were systematically recorded.Results The AD group exhibited significantly greater improvement in nasal itching compared to the MD group(median difference:-2 vs.0,U=118.5,P=0.04,effect size r=0.33).The AD group also demonstrated favorable trends toward improved sneezing,nasal congestion,rhinorrhea,and total VAS score,although these differences did not reach statistical significance.In the subgroup analysis by 2-hour intervals,the 16:00-18:00 subgroup showed greater symptom relief than the 8:00-10:00 subgroup,though the difference was not statistically significant.No significant differences were observed between the two groups in the incidence of total,local,or systemic adverse reactions(P>0.05),and no moderate or severe systemic adverse events occurred.Conclusions This preliminary retrospective analysis indicates that afternoon administration of dual-mite SCIT,particularly between 16:00 and 18:00,may enhance the improvement of nasal symptoms without elevating safety concerns.The timing of SCIT administration could therefore represent a promising avenue for treatment optimization.

Objective:To understand the incidence rate of herpes zoster (HZ) and postherpetic neuralgia (PHN) in Beijing, and analyze the incidence trend of HZ and PHN from 2015 to 2022.Methods:Cases of HZ and PHN from 2015 to 2022 were retrieved from the Hospital Information Systems (HIS) of all primary and above hospitals/clinics in three districts representing the urban, inner suburban, and outer suburban areas of Beijing. After duplication screening, the first visit cases were screened, and the incidence characteristics were described. The incidence rate of HZ and PHN in each year by sex and age group and the age-standardized incidence rate were calculated. The annual percentage increase (APC) of incidence rate was calculated using the Joint regression model, and the change trend was analyzed.Results:The age-standardized incidence rate of HZ in Beijing from 2015 to 2022 ranged from 7.44‰ to 10.05‰, with an average annual incidence rate of 8.95 ‰, significantly increasing with age ( P<0.001). The Joinpoint regression model showed that the overall age-standardized incidence of HZ remained relatively stable, with no significant difference (APC=2.28%, t=1.56, P=0.170). However, the incidence rate among the 0-19-year-old group exhibited a trend of decrease (APC=-10.70%, t=-6.29, P<0.001). For PHN, the age-standardized incidence in Beijing ranged from 0.77‰ to 2.67‰, with an average annual incidence rate of 1.59‰ and a proportion of 9.48% to 26.86% among HZ cases. Both the incidence of PHN and its proportion among HZ cases increased with age ( P<0.001). The age-standardized incidence of PHN increased annually (APC=18.56%, t=9.02, P<0.001). Conclusion:The incidence rate of HZ and PHN in Beijing continues to be at a high level, and PHN shows an increasing trend over time.

Hashimoto's thyroiditis(HT)is an autoimmune thyroid disease characterized by diffuse enlargement of thyroid gland and elevated thyroid autoantibodies.HT is closely related to emotional factors,conveyance and dispersion function of the liver,and the qi movement of the five zang organs.This paper explores the approach to the differentiation and treatment of HT based on Professor Yang Shuyu's view of regulation of both mind and body.In the view of regulation of both mind and body,the regulation of mind is to harmonize emotions,and the regulation of body refers to the conveyance and dispersion function of zang-fu organs.Based on the view of regulation of both mind and body,the pathological changes of HT are characterized by the disordered conveyance and dispersion of qi movement,and the stable phase,hyperthyroid phase,and hypothyroid phase of HT correspond to obstructed conveyance and dispersion,excessive conveyance and dispersion,and insufficient conveyance and dispersion,respectively.The emotional disorders caused by the failure of mind regulation exist throughout the disease course.Therefore,the treatment of HT can be conducted by using the therapies of unblocking,suppressing,and tonifying separately for stable phase,hyperthyroid phase,and hypothyroid phase to address the root cause,and then the conveyance and dispersion of visceral qi movement are restored.Besides,the therapeutic method of resolution is used to alleviate symptoms by removing goiter and dissipating nodules.Simultaneously,emotional regulation therapy is incorporated to achieve a comprehensive efficacy for harmonizing physique-spirit and mind-body through the regulation of emotions,conveyance and dispersion of qi movement,and visceral functions.The view of regulation of both mind and body provides new methods and approaches for traditional Chinese medicine management of HT.

Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

Objective:To explore the efficacy of intensive repetitive transcranial magnetic stimulation (irTMS) in treatment-resistant depression (TRD) and its impact on cognitive function and systemic immune-inflammation index (SII).Methods:Forty-eight TRD patients were divided into observation group and control group using random number table method, with 24 patients in each group. The observation group was treated with irTMS, and the stimulation site was the left dorsolateral prefrontal lobe. The stimulation intensity was 110% of the motor threshold, and the stimulation frequency was 15 Hz. The stimulation interval was 26 s, and 3 000 pulses were stimulated each time. Stimulating 5 times per day, with an interval of 50 min, and continuous treatment for 5 days. The total stimulation amount for 5 days was 75 000 pulses. The control group was treated with pseudo stimulation. Before treatment (T0), 5 days after treatment (T1), and 1 month after treatment (T2), 17-item Hamilton depression scale (HAMD-17) was used to assess depressive mood. Evaluating cognitive function using the Wisconsin card sorting test.A fully automated blood cell analyzer was used to detect platelet count (PLT), neutrophil count (NC), and lymphocyte count (LC), calculate the systemic immune inflammation index (SII), SII=PLT × NC/LC. Statistical analysis was conducted using SPSS 20.0 software. The comparison between two sets of repeated measurement data was performed using repeated measurement analysis of variance.Simple effect analysis was performed if the interaction effect was significant.Pearson analysis was used for correlation testing.Results:The interaction effect between the time and group of HAMD-17 scores was significant ( F=121.784, P<0.05). The results of simple effects analysis showed that the HAMD-17 scores of the observation group at T1 and T2 ((12.07±4.08) and (14.78±4.99), respectively) were lower than those of the control group ((23.78±5.87) and (24.67±7.00), P<0.05). The treatment response rate and remission rate of the observation group at T1 were higher than those of the control group ( χ2=4.090, 7.378, both P<0.05).The treatment response rate and remission rate of the observation group at T2 were higher than those of the control group ( χ2=4.463, 4.547, both P<0.05). The time and group interaction effects of the percentage of correct response and conceptualization level in the Wisconsin card sorting test were significant ( F=30.087, 20.004, P<0.05). The results of simple effects analysis showed that the percentage of correct response and conceptualization level in the observation group at T1 and T2 were higher than those in the control group (all P<0.05). The time and group interaction effect of SII was significant ( F=8.173, P<0.05). The results of simple effects analysis showed that there was no statistically significant difference in SII between the two groups at T0 ( P>0.05). The SII at T1 and T2 in the observation group was lower than that in the control group ( P<0.05). In the observation group, the changes in SII from T2 to T0 was positively correlated with the change in HAMD-17 scores ( r=0.527, P<0.05), and negatively correlated with the percentage of correct responses to the Wisconsin card sorting test ( r=-0.412, P<0.05) and the percentage of conceptualization level ( r=-0.411, P<0.05). Conclusion:irTMS is effective in treating TRD and can improve patients' cognitive function and immune inflammation damage.

Objective:To evaluate the expression of tertiary lymphoid structures (TLS) in renal tissues, and the relationship between TLS and clinicopathological changes and prognosis in idiopathic membranous nephropathy (IMN) patients.Methods:It was a single center retrospective study. The patients with IMN diagnosed by renal biopsy at Shengjing Hospital Affiliated to China Medical University from January 2018 to December 2020 were enrolled, and their clinicopathological data were collected. Immunohistochemistry was used to evaluate the expression of TLS in renal tissues. According to whether TLS expression in renal tissues was positive or not, the patients were divided into TLS-positive group and TLS-negative group, and the baseline differences in clinicopathological data between the two groups were compared. The clinical remission included complete remission and partial remission. Logistic regression analysis was used to analyze the correlation between serum phospholipase A2 receptor (PLA2R) antibody titer and positive TLS expression in renal tissues. Kaplan-Meier survival curve and log-rank test were performed to analyze the differences of proteinuria remission rates between TLS-positive and TLS-negative groups. Cox regression analysis was employed to identify the related factors of proteinuria remission. The receiver operating characteristic (ROC) curve was used to evaluate the value of TLS in predicting proteinuria remission.Results:A total of 120 IMN patients were included in this study, with age of 50.00 (40.00, 57.75) years and 78 (65.00%) males. The 24-hour urinary protein was (7.54±4.14) g, 89 (74.17%) patients were positive for serum PLA2R antibody, and the serum PLA2R antibody titer was 90.49 (48.88, 155.33) RU/ml. Immunohistochemical results showed that TLS was mainly distributed in the renal cortex glomeruli or around renal blood vessels in renal tissues. There were 43 patients in the TLS-positive group and 77 patients in the TLS-negative group. The positive rate of serum PLA2R antibody in the TLS-positive group was 83.72% (36/43). Compared with the TLS-negative group, the TLS-positive group had lower serum albumin ( t=-3.474, P<0.001) and estimated glomerular filtration rate ( Z=-2.076, P=0.045), while serum creatinine ( t=2.006, P=0.028), 24-hour urinary protein ( t=4.140, P<0.001), serum PLA2R antibody titer ( Z=4.628, P=0.001), glomerulosclerosis degree ( Z=2.403, P=0.019), and proportions of hypertension ( χ2=6.511, P=0.011), renal interstitial fibrosis ( χ2=4.088, P=0.043), renal interstitial inflammatory cell infiltration ( χ2=9.261, P=0.002), tubular atrophy ( χ2=4.936, P=0.026) and extremely high-risk of kidney disease progression ( χ2=9.352, P=0.002) were higher. Multivariate logistic regression analysis showed that serum PLA2R antibody titer was an independent factor correlated with positive TLS expression in renal tissues ( OR=1.014, 95% CI 1.007-1.021). The median follow-up time was 18.00 (95% CI 16.07-19.93) months. Kaplan-Meier survival curve showed that the proteinuria remission rate in the TLS-positive group was lower than that in the TLS-negative group (Log-rank χ2=9.339, P=0.002). Cox regression analysis showed that positive TLS expression was an independent factor correlated with proteinuria remission ( HR=0.228, 95% CI 0.177-0.297). ROC curve showed that TLS had a certain clinical predictive value for proteinuria remission ( AUC=0.703, 95% CI 0.608-0.798). Conclusions:IMN patients with positive TLS expression in renal tissues have a lower proteinuria remission rate, more severe pathological damage, and a higher risk of disease progression. TLS is expected to become a pathological marker for predicting the severity and prognosis of IMN.

Objective:To analyze the epidemiological and clinical characteristics of pertussis in children and the antimicrobial resistance pattern of Bordetella pertussis isolates in Anhui province in 2024. Methods:Prospective observational study. The demographic information of 4 233 cases of pertussis confirmed by nucleic acid testing in Anhui Provincial Children′s Hospital in 2024 and the clinical data of hospitalized cases were collected. The annual epidemic trend of pertussis in children, the clinical characteristics of hospitalized cases, and the vaccination status were analyzed. Bordetella pertussis isolates were recovered from nasopharyngeal swabs obtained from hospitalized children and their family caregivers during the outbreak period and antimicrobial susceptibility was tested. Results:Among the 4 233 children, 2 330 were male and 1 903 were female. A total of 4 059 cases (95.9%) occurred from March to September, with the peak of the disease from April to July (3 364 cases (79.5%)).There were 4 075 cases (96.3%) aged 9 years and under, among which 718 cases (17.0%) were under 1 year old and 2 494 cases (58.9%) were aged 4 to 7 years. During the outbreak period, there were a total of 301 hospitalized children (7.1%), with an average age of 4.4 (2.8, 16.5) months. Among them, 61 cases (20.3%) received the full course of vaccination (4 doses), 64 cases (21.3%) received partial doses of the vaccine, and 176 cases (58.5%) were unvaccinated. Among the unvaccinated children, 79.6% (172/216) were under 1 year old, 8.7% (2/23) were between 1 and 3 years old, and 3.2% (2/62) were 3 years old or older. None of the 20 cases (6.6%) of severe pertussis received pertussis vaccine.Among the 301 hospitalized children, 298 cases (99.0%) presented with typical paroxysmal spasmodic cough, 94 cases (31.2%) had vomiting after coughing, 82 cases (27.2%) had whooping sounds, and 54 cases (17.9%) had cyanotic attacks. There were 228 cases (75.7%) complicated with pneumonia and 5 cases (1.7%) with pertussis encephalopathy. The infection rate among the accompanying family members who underwent screening was 77.1% (371/481). Based on the minimum inhibitory concentration testing of 186 Bordetella pertussis isolates, the minimum inhibitory concentration 90 of azithromycin and trimethoprim-sulfamethoxazole were >256.000 and 0.050 mg/L, respectively. Conclusions:The peak of pertussis cases in Anhui region in 2024 occurred from April to July. Children aged ≤9 years were the major affected population. Infants and preschool children were most susceptible to pertussis. The intrafamily transmission rate of pertussis is high. Empirical use of macrolides for the treatment of pertussis is not recommended. Trimethoprim-sulfamethoxazole can be used as the preferred antibiotic for pertussis in children aged 2 months and above.
