Objective We sought to investigate the clinical characteristics and echocardiographic changes of cryptogenic perforator infarction（PI） patient with patent foramen ovale（PFO）. Methods From Jan 2015 to Dec 2023， patients diagnosed with cryptogenic stroke were retrospectively included in our study. All patients received transthoracic echocardiography（TTE） and transcranial Doppler（TCD）.PFO was diagnosed by the bubble test of TCD. Comparisons of clinical features and TTE findings were performed firstly in PI patients， between PFO and non-PFO， and then in patients with PFO， between PI and cortical infarction（CI）. Results A total of 251 patients were retrospectively analyzed. PFO was detected in 104 patients，of those，40.4%（42/104） had pure PI（PFO-PI） and 59.6%（62/104） had CI（PFO-CI）. In patients without PFO，30.6%（45/147） had pure PI（non-PFO-PI）.Compared with non-PFO-PI， PFO-PI associated with a higher proportion of vertebrobasilar circulation infarctions（VCI）（47.6% vs 17.8%， P=0.003）， lower mean value of left ventricle end-diastolic diameters（LVEDd）（47.3 mm vs 49.8 mm， P=0.037） and lower peak E-wave velocity（62.6 cm/s vs 70.8 cm/s，P=0.015）.In PFO patients， PFO-PI was detected with a lower mean value of aorta root diameters（32.5 mm，P=0.011） and lower mean value of LVEDd（47.3 mm，P=0.045） than PFO-CI（34.5 mm and 49.4 mm， respectively）. Conclusion Higher proportion of VCI was found in PFO-PI. Lower LVEDd， lower Em and without aortic root dilatation were three echocardiographic features associated with PFO-PI in cryogenic PI patients.

AIM:To investigate the effects of sodium hydrosulfide(NaHS)on hexokinase 2(HK2)-nucleo-tide-binding oligomerization domain-like receptor protein 3(NLRP3)-gasdermin D(GSDMD)pathway and pyroptosis in-duced by lung ischemia/reperfusion(I/R)in rats.METHODS:Male Sprague-Dawley rats were divided into 6 groups:control group,control+NaHS group,I/R group,low-dose NaHS+I/R(L+I/R)group,medium-dose NaHS+I/R(M+I/R)group,and high-dose NaHS+I/R(H+I/R)group,with 6 rats in each group.The NaHS was administered via intraperi-toneal injection at 1.5 mL,30 min before modeling.The left lung tissues were collected 30 min after ischemia and 1 h af-ter reperfusion,and the wet/dry weight ratio and total lung water content were recorded.Hematoxylin-eosin(HE)staining was used to examine lung tissue morphological changes.The levels of malondialdehyde(MDA),myeloperoxidase(MPO)and lactate in lung tissues were measured with test kits.ELISA was employed to determine the levels of interleukin-1β(IL-1β)and IL-18.The expression of glycolysis-and pyroptosis-related indicators was analyzed by Western blot,qRT-PCR and immunofluorescence staining.RESULTS:Compared with control group,the rats in NaHS group showed no signifi-cant differences in all laboratory tests(P>0.05).The rats in I/R group exhibited significant lung injury,oxidative stress,increased lactate level,and up-regulated glycolysis and pyroptosis(P<0.05 or P<0.01).Compared with I/R group,the indicators in L+I/R group showed a downward trend(P<0.01)or no difference(P>0.05),while those in M+I/R group dis-played a significant reduction(P<0.05 or P<0.01).However,the indexes in H+I/R group exhibited no significant dif-ferences in these tests(all P>0.05).CONCLUSION:A moderate dose(56 μmol·L-1·kg-1)of NaHS mitigated the oc-currence of pyroptosis by inhibiting the HK2-NLRP3-GSDMD pathway,thus contributing to the attenuation of lung I/R in-jury in rats.

Objective:To conduct a nationwide physician survey to better understand clinicians’ disease awareness, treatment patterns, and experience of Waldenstr?m macroglobulinemia (WM) in China.Methods:This cross-sectional study was conducted from February 2022 to July 2022 by recruiting clinicians with WM treatment experience from hematology, hematology-oncology, and oncology departments throughout China. Quantitative surveys were designed based on the qualitative interviews.Results:The study included 415 clinicians from 219 hospitals spread across thirty-three cities and twenty-two provinces. As for diagnosis, the laboratory tests prescribed by physicians for suspected WM patients were relatively consistent (92% -99% recommendation for laboratory, 79% -95% recommendation for pathology, 96% recommendation for gene testing, and 63% -83% recommendation for imaging examination). However, from a physician's perspective, there was 22% misdiagnosis occurred in clinical practice. The rate of misdiagnosis was higher in lower-level hospitals than in tertiary grade A hospitals (29% vs 21%, P<0.001). The main reasons for misdiagnosis were that WM was easily confused with other diseases, and physicians lacked the necessary knowledge to make an accurate diagnosis. In terms of gene testing in clinical practice, 96% of participating physicians believed that WM patients would require gene testing for MYD88 and CXCR4 mutations because the results of gene testing would aid in confirming diagnosis and treatment options. In terms of treatment, 55% of physicians thought that the most important goal was to achieve remission, while 54% and 51% of physicians wanted to improve laboratory and/or examination results and extend overall survival time, respectively. Among patients with treatment indications, physicians estimated that approximately 21% of them refused to receive treatment, mainly owing to a lack of affordable care and disease awareness. When selecting the most appropriate treatment regimens, physicians would consider patient affordability (63% ), comorbidity (61% ), and risk level (54% ). Regimens containing Bruton tyrosine kinase inhibitor (BTKi) were most widely recommended for both treatment-na?ve and relapsed/refractory patients (94% for all patients, 95% for treatment-na?ve patients, and 75% for relapsed/refractory patients), and most physicians recommended Ibrutinib (84% ). For those patients who received treatment, physicians reported that approximately 23% of patients did not comply with the treatment regimen due to a lack of affordability and disease awareness. Furthermore, 66% of physicians believe that in the future, increasing disease awareness and improving diagnosis rates is critical. Conclusions:This study is the first national physician survey of WM conducted in China. It systematically describes the issues that exist in WM diagnosis and treatment in China, such as a high rate of misdiagnosis, limited access to gene testing and new drugs, and poor patient adherence to treatment. Chinese doctors believe that improving doctors’ and patients’ understanding of WM is one of the most urgent issues that must be addressed right now.

Peri-implantitis,as a common complication after implant restoration,seriously affects the prognosis of the patients and causes a lot of inconvenience to the normal life of the patients,and its pathogene-sis is not entirely clear.In recent years,laser therapy,photodynamic therapy,local sustained-release drug-load-ed materials and many other emerging technologies have been gradually applied in clinical practice,and have played a positive promoting role in the treatment of peri-implantitis.However,the research on the application of local sustained-release materials in peri-implantitis is still in the initial stage,and there is a lack of systemat-ic induction and summary of relevant research literatures.This article reviews the research status quo,treat-ment status quo and application of emerging local sustained-release drug-loaded materials for peri-implantitis by consulting domestic and foreign literatures,so as to provide reference for clinical research and application.

Objective To investigate the genetic risk factors of deep vein thrombosis(DVT)after trauma.Methods In a nested case-control study,50 patients with DVT after traumatic lower extremity fractures and 50 patients without DVT were recruited.The two groups were matched with gender,age and fracture sites.Preoperative venography was performed to diagnose DVT in trauma patients.Genome wide association study(GWAS)was used to investigate the genetic risk factors for preoperative DVT after traumatic lower ex-tremity fractures.Genomic DNA in leukocytes from blood sample was extracted and used for GWAS.Results GWAS was conducted based on 2 662 single nucleotide variants(SNV)which were dispersed in 144 interested genes.Ten genes were found to have signifi-cant association with trauma-related DVT,including cofactors of hemostasis mechanism,i.e.,THBD,F5,SERPIND1 and ITGA2,the factors related to vitamin K-dependent(VKD)carboxylation,i.e.,GGCX and CALU,and the members of cytochrome P450 family,i.e.,CYP1A1,CYP3A4,CYP2C19 and CYP2B6.Conclusion DVT after trauma might be regulated by the cofactors of hemostasis mechanism,the factors related to VKD carboxylation and the members of cytochrome P450 family.The results of our study may provide reference and inspiration for genetic susceptibility of preoperative DVT after trauma.

Diabetes is a common chronic non-infectious disease. Diabetic patients not only suffer from metabolic disorders, but are also prone to immune deficiencies and are at a higher risk of being infected with human papillomavirus (HPV). Many studies at home and abroad have shown that the HPV infection rate of patients with diabetes is higher than that of non-diabetic patients. Patients with diabetes can benefit from HPV vaccination, and the tolerance is good. HPV vaccination is recommended for diabetic patients. This article reviews the research on diabetes, HPV infection, and HPV vaccine, which will provide references for HPV vaccination in diabetic patients.
