ObjectiveTo investigate the mechanism by which Feixin decoction treats hypoxic pulmonary hypertension （HPH） by regulating the peroxisome proliferator-activated receptor gamma （PPARγ）/nuclear factor-kappa B （NF-κB）/NOD-like receptor pyrin domain containing 3 （NLRP3） signaling pathway. MethodsForty-eight male SD rats were randomly allocated into normal， hypoxia， and low-， medium- and high-dose （5.85， 11.7， 23.4 g·kg^-1， respectively） Feixin decoction groups， with 8 rats in each group. Except the normal group， the remaining five groups were placed in a hypoxia chamber with an oxygen concentration of （10.0±0.5）% for 8 h per day， 28 days， and administrated with corresponding drugs during the modeling process. After 4 weeks of treatment， echocardiographic parameters ［pulmonary artery acceleration time （PAT）， pulmonary artery ejection time （PET）， right ventricular anterior wall thickness （RVAWd）， and tricuspid annular plane systolic excursion （TAPSE）］ were measured for each group. The right ventricular systolic pressure （RVSP） was measured by the right heart catheterization method， and the right ventricular hypertrophy index （RVHI） was calculated by weighing the heart. The pathological changes in pulmonary arterioles were observed by hematoxylin-eosin staining. The co-localization of α-smooth muscle actin （α-SMA） with NLRP3， N-terminal gasdermin D （N-GSDMD）， and cysteinyl aspartate-specific proteinase-1 （Caspase-1） in pulmonary arteries was detected by immunofluorescence. The protein levels of PPARγ， NF-κB， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， N-GSDMD， interleukin-1β （IL-1β）， interleukin-18（IL-18）， and cleaved Caspase-1 in the lung tissue was determined by Western blot. The ultrastructural changes in pulmonary artery smooth muscle cells （PASMCs） were observed by transmission electron microscopy. ResultsCompared with the normal group， the hypoxia group showed increased RVSP and RVHI （P<0.01）， decreased right heart function （P<0.01）， increased pulmonary vascular remodeling （P<0.01）， increased co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 in pulmonary arterioles （P<0.01）， up-regulated protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， a down-regulated protein level of PPARγ （P<0.05， P<0.01）， and pyroptosis in PASMCs. Compared with the hypoxia group， Feixin decoction reduced RVSP and RVHI， improved the right heart function and ameliorated pulmonary vascular remodeling （P<0.05， P<0.01）， decreased the co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， up-regulated the protein level of PPARγ （P<0.05， P<0.01）， and alleviated pyroptosis in PASMCs. ConclusionFeixin decoction can ameliorate pulmonary vascular remodeling and right heart dysfunction in chronically induced HPH rats by regulating pyroptosis in PASMCs through the PPARγ/NF-κB/NLRP3 pathway.

This paper reports a case of a patient with sleep-related painful erections treated by acupuncture combined with abdominal vibration therapy. The main symptom was repeated painful penile erections during nighttime sleep. The syndrome was differentiated as "water failing to nourish wood" and "liver qi stagnation". Acupuncture was applied at Baihui (GV20), Sishencong (EX-HN1), Guanyuan (CV4), and bilateral Neiguan (PC6), Hegu (LI4), Taichong (LR3), Taixi (KI3), Guilai (ST29), Yongquan (KI1), Yanglingquan (GB34), and Sanyinjiao (SP6). The treatment was combined with abdominal vibration therapy. Treatment was given once daily, five times per week. After the first treatment, the severity and duration of nocturnal erection pain were reduced, and sleep quality was improved. After two weeks of treatment, nocturnal erection pain persisted but became tolerable, with significantly shortened duration.

Objective To investigate the safety and effectiveness of endovascular treatment in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)over 24 h after onset.Methods The clinical data of AIS-LVO patients who received endovascular treatment in Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2022 were retrospectively analyzed,including baseline characteristics,imaging findings,treatment,degree of vascular recanalization(modified thrombolysis in cerebral infarction grade 2b and 3 for successful recanalization)and prognosis.Results A total of 57 patients were included,including 42 males and 15 females,aged from 30 to 84 years old.The most common risk factors were hypertension(39 cases,68.4%),followed by smoking history(24 cases,42.1%),diabetes mellitus(17 cases,29.8%),previous stroke history(16 cases,28.1%),and atrial fibrillation(9 cases,15.8%).Before treatment,the National Institutes of Health stroke scale score was 12.84±7.04,and the Alberta Stroke Program early computed tomography score was 9.00(7.00,10.00).Vascular occlusion sites included middle cerebral artery occlusion in 27(47.4%)cases,internal carotid artery occlusion in 24(42.1%)cases,and tandem lesions in 6(10.5%)cases.The time from onset to femoral artery puncture was 38.30(28.17,53.71)h,and the time from femoral artery puncture to vascular recanalization was 52.00(38.50,92.50)min.General anesthesia was the main anesthesia method,accounting for 64.9%(37/57).The etiological types of stroke were mainly large artery atherosclerosis(38 cases,66.7%),cardiogenic embolism(9 cases,15.8%),unknown causes(6 cases,10.5%),and other clear causes(4 cases,7.0%).Mechanical thrombectomy was the first choice in 41(71.9%)cases,balloon dilatation/stenting was used in 35(61.4%)cases,of which 15(26.3%)cases were the first choice.Finally,53(93.0%)cases were recanalized successfully.In terms of complications,1(1.8%)case had symptomatic intracranial hemorrhage.The 90-d prognosis rate was 59.6%(34/57),and 3(5.3%)cases died.Conclusion Endovascular treatment for AIS-LVO patients over 24 h after onset has high recanalization rate and good safety,but it still needs to be further verified by randomized controlled trials.

Objective To explore the five-circuit and six-qi features of birth time and onset time of children with acute lymphoblastic leukemia(ALL).Methods A total of 877 cases of children with ALL from Children's Hospital of Soochow University from June 2021 to February 2023 were collected,and their five-circuit and six-qi features of birth time and onset time were analyzed.And then the correlation of five-circuit and six-qi features of birth time and onset time with ALL was explored preliminarily,and the pathogenic characteristics of congenital factors and acquired pathogenic factors were revealed.Results(1)The children who were born in the year with the heavenly stems being bing(the 3rd of the ten heavenly stems)and ding(the 4th of the ten heavenly stems)and with the earthly branches being shen(the 8th of the twelve earthly branches)and you(the 9th of the twelve earthly branches)are prone to suffer from ALL,and the birth year of children with ALL had the five-circuit and six-qi features of the joining of guest circuit with dominant circuit being rebellious.ALL is commonly seen in the year with the heavenly stems being geng(the 7th of the ten heavenly stems)and xin(the 8th of the ten heavenly stems)and with the earthly branches being zi(the 1st of the twelve earthly branches)and chou(the 2nd of the twelve earthly branches),and the onset year of ALL in children had the five-circuit and six-qi features of the yearly circuit being gold-circuit and water-circuit,sitian-zaiquan yearly circuit qi being shaoyin monarch-fire with yangming dryness-gold,taiyin damp-earth with taiyang cold-water,and the qi-circuit assimilation relationship being celestial correspondence,same celestial correspondence,celestial correspondence in convergent year,disharmony,mildly-rebellious,and celestial restriction.Conclusion Gold-dryness and water-cold are the congenital factors and acquired pathogenic factors of ALL.The onset of ALL in children is closely related to qi insufficiency and qi stagnation of wood and fire in five-circuit and six-qi theory.

Objective To target at the NKG2A-HLA-E inhibitory axis,a pluripotent stem cell(iPSC)-derived geneti-cally engineered natural killer cells(NK cells)with NKG2A knockout(NKG2A KO-iNK)were prepared and then their tumor-killing efficacy was evaluated in vitro.Methods NKG2A was knocked out in iPSCs using gene-editing technology.These cells were then differentiated into NKG2A KO-iNK cells.Surface markers at each differentiation stage were analyzed by flow cytometry.Western blot confirmed NKG2A knockout,and flow cytometry assessed expres-sion of activating receptors(NKG2D)and natural cytotoxicity receptors(NKp30,NKp44,NKp46)in NKG2A KO-iNK cells.Cytotoxic activity against tumor cell lines with varying human leukocyte antigen E(HLA-E)expression level was evaluated via lactate dehydrogenase(LDH)release assay.Results Co-transfection of iPSCs with Cas9 pro-tein and three small-guide RNAs(sgRNAs)targeting at exons 1 and 2 of the KLRC1 gene(encoding NKG2A)suc-cessfully generated monoclonal NKG2A-knockout iPSCs(NKG2A KO-iPSCs)with a single T-base insertion in exon 1.During iPSC differentiation into NK cells,CD34 expression reached 30％-50％at the embryoid body(EB)stage(day 8),while CD56 and CD 16 expression exceeded 80％by day 28.Western blot confirmed complete NKG2A knockout in NKG2A KO-iNK cells.Flow cytometry revealed comparable expression level of activating receptor NKG2D and cytotox-icity receptors(NKp30,NKp44,NKp46)between NKG2A KO-iNK and wild-type iNK(WT-iNK)cells.The LDH assay results indicated that the cytotoxic activity of NKG2A KO-iNK cells against the HLA-E highly-expressed B-cell precursor leukemia cell line Nalm6 cells was significantly higher than that of WT-iNK cells,while there was no signif-icant difference between them and human myeloma cell line H929 cells with low HLA-E expression and human hepa-tocellular carcinoma cell line HepG2 cells with almost no HLA-E expression.Interferon-γ(IFN-γ)pretreatment up regulated HLA-E expression in Nalm6 cells,further amplifying NKG2A KO-iNK-mediated cytotoxicity.Conclusions By disrupting the NKG2A-HLA-E inhibitory axis,NKG2A KO-iNK cells exhibit markedly enhanced in vitro cytotoxic-ity against HLA-E-high tumor cells.This result highlights their potential function as a novel adoptive cell therapy strategy for cancers reliant on HLA-E-mediated immune evasion.

Objective To investigate the therapeutic effect of combination treatment of transcatheter arterial chemoembolization(TACE),micro wave ablation(MW A)and targeted immunotherapy for hepatocellular carcinoma(HCC).Methods The clinical data of HCC patients,who were admitted to the Affiliated Central Hospital of Jiangnan University of China to receive TACE from August 2016 to August 2023,were retrospectively analyzed.Based on the inclusion criteria,a total of 252 patients were included in this study.According to the therapeutic scheme,the patients were divided into combination group(receiving TACE,MWA,targeted therapy and immunotherapy,n=41),and control group(receiving TACE alone,n=211).The overall survival(OS)and progression-free survival(PFS)of the two groups were statistically analyzed.After propensity score matching at 1∶1 ratio,the clinical effects of the two groups were analyzed.According to different data,t-test,test,Kaplan-Meier curve,logarithmic rank test,Cox regression analysis,or Cox proportional risk model analysis was used to make statistical analysis.Results Multivariate regression analysis showed that tumor number,maximum diameter,invasion of large vessels,tumor capsule,AFP level,glutamic oxalacetic transaminase,BCLC stage and Child-Pugh stage were the independent risk factors for patient survival.Imaging response and combination treatment were the protective factors for survival.After propensity score matching,a total of 37 pairs of patients were obtained,and the baseline data were comparable between the groups.The differences in OS and PFS between the two groups were statistically significant.Combination treatment of TACE,MWA,targeted therapy and immunotherapy could significantly prolong OS and PFS in HCC patients.Conclusion Compared with TACE alone,combination use of TACE,MWA,targeted therapy and immunotherapy is a more effective therapeutic scheme for HCC,it can remarkably and effectively improve OS and PFS in HCC patients.

Objective To analyze the risk of postoperative ileus in severe ulcerative colitis(UC)patients undergoing total proctocolectomy with ileal pouch-anal anastomosis(TPC-IPAA)and develop and validate a nomogram prediction model.Methods A total of 278 severe UC patients un-dergoing TPC-IPAA from January 2018 to May 2022 were enrolled and divided into ileus group(n=73)and non-ileus group(n=205)based on the occurrence of postoperative ileus.Another 120 severe UC patients undergoing TPC-IPAA from June 2022 to April 2023 were selected as validation cohort(with a 7-to-3 ratio between the modeling cohort and the validation cohort).Factors influen-cing postoperative ileus in severe UC patients undergoing TPC-IPAA were analyzed to construct a No-mogram prediction model.The discrimination,consistency,and clinical utility of the Nomogram model were evaluated by the receiver operating characteristic(ROC)curve,calibration curve,and decision curve analysis(DC A).Results There were no significant differences in general characteristics be-tween the modeling cohort and the validation cohort(P＞0.05).Significant differences were ob-served in preoperative American Society of Anesthesiologists(ASA)classification,preoperative al-bumin level,history of abdominal surgery,surgical approach,operation duration,intraoperative blood loss,and postoperative intra-abdominal infection between the ileus group and the non-ileus-group(P＜0.05).Preoperative ASA classification,preoperative albumin level,history of abdomi-nal surgery,operation duration,intraoperative blood loss,and postoperative intra-abdominal infec-tion were independent influencing factors for postoperative ileus in severe UC patients undergoing TPC-IPAA(P＜0.05).The ROC curve showed that the area under the curve of the Nomogram model for predicting postoperative ileus in severe UC patients undergoing TPC-IPAA was 0.782(95％CI,0.723 to 0.842)in the modeling cohort and 0.785(95％CI,0.693 to 0.878)in the validation cohort,indicating good discrimination of the model.The calibration curve demonstrated good consistency of the nomogram model.The DCA curve suggested high clinical utility of the Nomogram model.Conclusion The risk of postoperative ileus in severe UC patients undergoing TPC-IPAA is influenced by preoperative ASA classification,history of abdominal surgery,preopera-tive albumin level,intraoperative blood loss,operation duration,and postoperative intra-abdominal infection.The nomogram prediction model developed based on these factors has high predictive per-formance for the risk of postoperative ileus.

BACKGROUND: To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study. METHODS: This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well. RESULTS: The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P  <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n  = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β  <0, P  <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed. CONCLUSIONS: The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR2200055247).
