AIM To investigate the ameliorative effects of Schisandrol A(Sol A)in Suhuang antitussive capsule on post-infectious cough(PIC).METHODS The in vivo mouse PIC model was established by intratracheal instillation of lipopolysaccharide(LPS)combined with cigarette smoke exposure.The mice were randomly divided into the control group,the model group,the Suhuang antitussive capsule group(14 g/kg),the montelukast sodium positive control group(3 mg/kg),and low and high dose Sol A groups(10,30 mg/kg).The in vitro PIC model was established by stimulating human bronchial epithelial cells(BEAS-2B)with LPS.The cells were divided into the control group,the model group,the Suhuang antitussive capsule group(10 μg/mL)and low and high dose Sol A groups(3,10 μmol/L).HE and Masson staining were used to detect the pathological changes of the lung and bronchial tissues.ELISA was used to detect the levels of IL-1β,IL-6,TNF-α,ROS,MDA,SOD and GSH in the lung tissues.RT-qPCR was used to detect the IL-1β,IL-6 and TNF-α mRNA expressions in BEAS-2B cells.And Western blot was applied to detect the protein expressions of p-PI3K,p-Akt,NOX4,SIRT1,p-ERK,Fibronectin,E-cadherin,Vimentin and α-SMA in mouse lung tissue and BEAS-2B cells.RESULTS Compared with the model group,the groups intervened with Sol A or Suhuang antitussive capsule displayed prolonged cough latency(P＜0.01);reduced cough frequency(P＜0.01);relieved pulmonary inflammatory cell infiltration and collagen deposition in PIC mice;decreased pulmonary levels of IL-1β,IL-6,TNF-α,ROS,MDA and protein expressions of Fibronectin,Vimentin,α-SMA,p-ERK,p-PI3K,p-Akt,and NOX4(P＜0.05,P＜0.01);increased pulmonary levels of SOD and GSH and protein expressions of E-cadherin and SIRT1(P＜0.05,P＜0.01);decreased ROS level,IL-1β,IL-6,TNF-α mRNA expressions and p-ERK,p-PI3K,p-Akt,NOX4 protein expressions in vitro(P＜0.05,P＜0.01);and increased SIRT1 protein expression in vitro as well(P＜0.01).CONCLUSION Being the main antitussive component of Suhuang antitussive capsule upon the PIC model,Sol A inhibits the inflammation via SIRT1/ERK signaling pathway and relieve the oxidative stress via PI3K/Akt/NOX4 signaling pathway.

AIM To explore the effects of praeruptorin A from Suhuang antitussive capsules on cough variant asthma(CVA).METHODS The rats were randomly divided into the normal group,the model group,the dexamethasone group(0.5 mg/kg),the Suhuang antitussive capsules group(7 g/kg)and the low,medium and high dose praeruptorin A groups(15,30 and 60 mg/kg).The rat model of CVA was established by intraperitoneal injection of sensitizer(1 mg/mL ovalbumin and 10 mg/mL aluminum hydroxide)and aerosol inhalation of 1%ovalbumin followed by the corresponding dosing of drugs by gavage initiated on the 14th day.Another 14 days later,the rats had their pathological pulmonary changes observed by HE,Masson and PAS stainings;their number of inflammatory cells in bronchoalveolar lavage fluid(BALF)detected by hematology analyzer;and their levels of IL-4,IL-5,IL-13 and MUC5AC in BALF detected by ELISA.The RAW264.7 cell inflammatory model induced by lipopolysaccharide(LPS)was treated with 4,8,16 μmol/L praeruptorin A or 0.25 mg/mL Suhuang antitussive capsules,respectively.And the cells had their NO level detected by Griess method,and their ROS expression observed using fluorescence microscopy.The detections of the pulmonary and cellular mRNA expressions of IL-6,IL-1β,COX-2,iNOS and PPAR-γ by RT-qPCR;and the protein expressions of p-P65,P65,p-IκBα,IκBα,NLRP3,caspase-1(p20)and IL-1β by Western blot were conducted in both the cells and the rats.RESULTS The in vivo result showed that praeruptorin A reduced the cough frequency(P＜0.01);prolonged the cough latency(P＜0.05,P＜0.01);reduced the number of eosinophils and neutrophils in BALF(P＜0.05,P＜0.01);decreased the levels of IL-4,IL-5,IL-13 and MUC5AC in BALF and the pulmonary mRNA expressions of IL-6,IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);and decreased the phosphorylation of P65 and IκBα protein and NLRP3,caspase-1(p20)and IL-1β protein expressions(P＜0.05,P＜0.01)as well.The in vitro result showed that praeruptorin A inhibited the release of LPS-induced NO and reduce the ROS level(P＜0.01);decreased the mRNA expressions of IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);increased PPAR-γ mRNA expression(P＜0.05),and decreased the phosphorylation of P65 and IκBα protein and the expression of NLRP3 protein(P＜0.05,P＜0.01).CONCLUSION Praeruptorin A,one of the main antitussive components of Suhuang antitussive capsules,may improve CVA because of its anti-inflammatory and antitussive role by inhibiting the activation of NF-κB signaling pathway and reducing the expression of NLRP3 inflammatory corpuscles.

Objective: To investigate the clinical and molecular biological characteristics of patients with accelerated chronic lymphocytic leukemia (aCLL) . Methods: From January 2020 to October 2022, the data of 13 patients diagnosed with aCLL at The First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed to explore the clinical and molecular biological characteristics of aCLL. Results: The median age of the patients was 54 (35-72) years. Prior to aCLL, five patients received no treatment for CLL/small lymphocytic lymphoma (SLL), while the other patients received treatment, predominantly with BTK inhibitors. The patients were diagnosed with aCLL through pathological confirmation upon disease progression. Six patients exhibited bulky disease (lesions with a maximum diameter ≥5 cm). Positron emission tomography (PET) -computed tomography (CT) images revealed metabolic heterogeneity, both between and within lesions, and the median maximum standardized uptake value (SUVmax) of the lesion with the most elevated metabolic activity was 6.96 (2.51-11.90). Patients with unmutated IGHV CLL accounted for 76.9% (10/13), and the most frequent genetic and molecular aberrations included +12 [3/7 (42.9% ) ], ATM mutation [6/12 (50% ) ], and NOTCH1 mutation [6/12 (50% ) ]. Twelve patients received subsequent treatment. The overall response rate was 91.7%, and the complete response rate was 58.3%. Five patients experienced disease progression, among which two patients developed Richter transformation. Patients with aCLL with KRAS mutation had worse progression-free survival (7.0 month vs 26.3 months, P=0.015) . Conclusion: Patients with aCLL exhibited a clinically aggressive course, often accompanied by unfavorable prognostic factors, including unmutated IGHV, +12, ATM mutation, and NOTCH1 mutation. Patients with CLL/SLL with clinical suspicion of disease progression, especially those with bulky disease and PET-CT SUVmax ≥5, should undergo biopsy at the site of highest metabolic uptake to establish a definitive pathological diagnosis.

Objective:To investigate the feasibility of anthocyanins(C3G)antioxidant inhibition of autophagy to al-leviate epilepsy.Methods:Seventy-five SD rats were randomly divided into 5 groups:Control group,pentetrazole(PTZ)group,hydrogen peroxide(H2O2)intervention group,3-methyladenine(3-MA)intervention group,and C3G intervention group.The seizure grade,latency,and frequency were documented.Electroencephalography was employed to detect abnormal electrical discharges in the brain across.Patch clamp technique was utilized to measure action poten-tials in hippocampal neurons for each group.The concentration of 4-hydroxynonenoic(4-HNE)hippocampus was deter-mined using a specific kit.Ultrastructural alterations in hippocampal neurons were examined through electron microsco-pyissl staining was performed to assess neuronal damage within the hippocampus.Immunohistochemical staining and Western Blot were conducted to evaluate expression levels of 15-LOX,GPX4,and LC3 proteins within the hippocampus of rats.Results:Compared with the control group,the PTZ group was completely ignited and the modeling was success-ful.Compared with other epilepsy groups,the seizure grade of C3G group decreased,abnormal discharge decreased,latency increased,hippocampal neuron excitability decreased,nishi content increased,4-HNE content,15-LOX expression and LC3Ⅱ/LC3Ⅰ ratio decreased,but GPX4 expression increased(P＜0.05).Conclusion:The oxidative stress induced by epilepsy can induce excessive autophagy of neurons,and C3G can alleviate the occurrence and devel-opment of epilepsy by anti-oxidation and inhibition of autophagy.

As the main cause of secondary operation and postoperative death, the incidence of intraperitoneal infectious complications varies significantly in different medical centers in China. Due to the lack of national data, it is not possible to assess and develop appropriate diagnosis and treatment strategies properly. To provide a high-quality data platform for complication registration and clinical research, a multicenter prospective database for the Prevalence of Abdominal Complications After GastroEnterological surgery was established. Based on the Hospital Information System (HIS)of 20 medical centers in China, the electronic case reporting form (e-CRF) listed on the website was used to collect medical information of patients undergoing gastric or colorectal cancer surgery. The data were verified by on-site auditing, and data cleaning was performed by R software. After the data cleaning, the data in the database was checked and evaluated by the principle investigators and data administrators. When all data queries and questions were corrected and answered, the database was locked to establish a multicenter prospective database for postoperative abdominal infectious complications (the PACAGE database). The PACAGE database has rich information resources and high data quality and is a good data platform for complication registration and clinical research.

Objective: To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD. Methods: A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD. Results: The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD. Conclusion There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.

ObjectiveTo investigate the mechanism of interleukin-35（IL-35）/signal transducer and activator of transcription 3（STAT3）inhibition of eosinophil activation against allergic rhinitis（AR） by Bifukang. MethodOne hundred patients were randomly divided into a control group and a treatment group，50 cases in each group. The control group was given mometasone furoate nasal spray，and the treatment group was given Bifukang by nasal packing. The course of treatment was 28 days. The clinical efficacy，nasal classification and visual analogue scale（VAS） score of the two groups were observed before and after treatment. Enzyme linked immunosorbent assay（ELISA） was used to detect the expression levels of inflammatory factors ［interleukin（IL）-4，IL-10，IL-17，IL-35］ and Eotaxin and CC chemokine receptor-3（CCR3）in serum and nasal secretion of the two groups. The expression levels of STAT1，STAT3 and STAT4 were detected by real-time polymerase chain reaction（Real-time PCR）.The content of immunoglobulin G（IgG） and the ratio of CD4⁺/CD8⁺were detected by ELISA and flow cytometry. ResultAfter treatment， compared with before treatment， the levels of IL-4 and IL-17 in serum and nasal secretion in 2 groups were decreased， while the levels of IL-10 and IL-35 were increased （P<0.05， P<0.01）. The expression of STAT1， STAT2 and STAT3 in nasal secretions were significantly decreased （P<0.05）. IgG and CD4⁺/CD8⁺ were decreased， and the differences were statistically significant （P<0.05， P<0.01）.After treatment，compared with the control group，the levels of IL-4 and IL-17 in serum and nasal secretions of the treatment group were decreased，while the levels of IL-10 and IL-35 were increased （P<0.05）. The expression of STAT1，STAT3 and STAT4 in the treatment group was significantly inhibited compared with the control group after treatment （P<0.05）. In addition， the post-treatment serum CD4⁺/CD8⁺ and immunoglobulin G （IgG） levels were reduced in the treatment group compared with those of the control group （P<0.05， P<0.01）. During the treatment，there were no abnormal changes in heart，liver，kidney function and routine blood and urine tests in the two groups. ConclusionBifukang has a good effect on allergic rhinitis，and its mechanism may be related to the regulation of IL-35/STAT3 pathway，the inhibition of eosinophil activation and the improvement of related immune function.

Alzheimer's disease(AD) is a chronic progressive neurodegenerative disease with recent memory impairment as the main clinical manifestation and senile plaques and neurofibrillary tangles as the main pathological changes. In recent years, the effect of microRNAs on AD has attracted widespread attention. Patients with AD have abnormal expression of miRNA, which is closed related to regulation of AD pathophysiology-related genes. Therefore, this paper first elaborated neuroprotective and toxic effects of microRNA in AD, and then explored relevant traditional Chinese medicines that can regulate miRNA in the treatment of AD, so as to provide basis for revealing the pathogenesis relationship between miRNA and AD and provide ideas for further development of anti-AD traditional Chinese medicine.
