Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Objective To explore the clinical efficacy of omacycline(OMC)in the treatment of diabetes mellitus complicated with community-acquired bacterial pneumonia(CABP).Methods Clinical data of T2DM patients with CABP admitted to The First Hospital of Jiaxing from August 2022 to July 2023 were divided into OMC group and non-OMC(NOMC)group according to wheter they received OMC treatment or not.The absorption of pulmonary lesions after treatment,changes in inflammatory indicators[white blood cell count(WBC),C-reactive protein(C-reactive protein,CRP),and anterior calcitonin(procalcitonin,PCT)],comprehensive index[hospitalization days,total hospitalization costs,blood glucose standard within 3 d and glucocorticoid use]and the occurrence of adverse reactions were analyzed and compared.Results A total of 100 diabetes mellitus patients with CABP were included in this study,including 36 cases in OMC group and 64 cases in NOMC group.The absorption of pulmonary inflammation in the OMC group was significantly higher than that in the NOMC group(P<0.05).Before treatment,there was no statistical difference in WBC,CRP and PCT between the two groups(P>0.05).After treatment,WBC,CRP,and PCT in both groups were significantly lower than those before treatment(P<0.05).Furthermore,WBC,CRP,PCT levels,hospital stay,total hospitalization costs and glucocorticoid use rate were significantly lower in the OMC group than in the NOMC group(P<0.05).The blood glucose compliance rate within 3 d in the OMC group was significantly higher than that in the NOMC group(P<0.05).None of the patients had serious complications during the treatment period.Conclusion OMC treatment of T2DM complicated with CABP is helpful for early disease control and rehabilitation,and reduces the treatment burden.

Objective:To investigate the clinical characteristics and prognosis of single center adult chronic myeloid leukemia in chronic phase(CML-CP).Methods:Clinical data of 41 adult CML-CP patients in Department of Hematology,Shanghai Fengxian District Central Hospital from January 2015 to May 2021 were retrospectively analyzed.The clinical characteristics and prognosis of patients between＜60 years group and ≥ 60 years group were compared.Results:The 41 patients included 27(65.9％)males and 14(34.1％)females.The median age of the patients was 56(19-84)years,with 22 cases(53.7％)＜60 years and 19 cases(46.3％)≥60 years.Univariate analysis indicated that the proportions of patients with comorbidities,intermediate/high-risk Sokal score,myelofibrosis,and lactate dehydrogenase ≥1 000 U/L were significantly increased in ≥60 years group compared with＜60 years group at initial diagnosis(all P＜0.05).There were no statistical differences in the distribution of sex,ELST score,white blood cell count,platelet count,peripheral blood basophil percentage,peripheral blood eosinophil percentage and bone marrow primitive cell percentage between the two groups(P＞0.05).The proportion of patients taking reduced-dose imatinib in≥60 years group significantly increased(P＜0.001).Patients＜60 years had a higher proportion of molecular biological remission after treatment of tyrosine kinase inhibitors(TKIs)than patients ≥ 60 years(P＜0.001).The incidence of non-hematologic adverse reactions to TKI therapy significantly increased in patients ≥ 60 years(P＜0.001).Multivariate analysis showed that no adverse factors affecting the efficacy and prognosis of TKI.Conclusion:Compared with adult CML-CP patients＜60 years,patients ≥ 60 years gain fewer benefits from TKI treatment and increased adverse reactions.

Objective:To summarize the clinical characteristics of patients with combined pneumocystis jiroveci pneumonia (PJP ) after allogeneic hematopoietic stem cell transplantation (allo-HSCT ). Methods:The clinical manifestations,laboratory tests,imaging findings,and treatment outcomes of 21 allo-HSCT patients with PJP diagnosed at the First Affiliated Hospital of Soochow University and Soochow Hopes Hematology Hospital from July 2018 to July 2023 were retrospective analyzed.Results:Among the 21 patients,the male-to-female ratio was 2.5:1,and the median age was 36 years old with a range of 15-62 years.The median time to diagnosis of PJP after transplantation was 225 days.The clinical manifestations lack specificity,and the main clinical symptoms include respiratory symptoms (dyspnea,cough,sputum,etc.) and fever.Laboratory examination revealed peripheral blood lymphocyte counts decreased in 15 cases,CD4+T lymphocyte absolute values less than 200 cells/μl in 19 patients,C-reactive protein levels significantly increased in 20 patients,lactate dehydrogenase levels increased in 14 patients,and 1,3-β-D-glucan detection levels increased in 14 patients.Chest CT manifestations can be divided into three types:ground glass type,nodular type,and mixed type.Among them,the incidence of ground glass type was the highest (18/21),with 2 cases of nodular type and 1 case of mixed type.The sequence number of Pneumocystis jiroveci was detected through mNGS (15-57570),and 11 patients had mixed infections.In terms of treatment,TMP-SMX,Caspofungin,and methylprednisolone were administered,and 17 patients achieved improvement in their condition.Four patients died,all of whom died from respiratory failure.Conclusion:PJP is a critically ill condition after hematopoietic stem cell transplantation,and diagnosis is difficult.Early diagnosis can achieve better prognosis.The sensitivity of mNGS in diagnosing PJP is high,providing the possibility of early and accurate diagnosis for clinical practice,which is worthy of application and promotion.

Objective To investigate the mechanism by which lectin-like oxidized low density lipoprotein receptor-1(LOX-1)regulates hyperglycemic-induced myocardial fibroblast(CFs)fibrosis through the glycogen synthase kinase-3β(GSK-3β)/signal transducer and activator of transcription 3(STAT3)pathway.Methods CFs were isolated,cultured and identified.LOX-1 RNAi lentiviral vector was constructed and infected CFs.The experimental groups were as follows:Normal control(NC)group,High glucose(HG)group,LV-LOX-1,LV-Con group,Hypertonic(HPG)group.After LV-LOX-1 and LV-Con were infected with CFs,adding 25 mmol/L glucose to culture CFs for 24 h,they were denoted as HG+LV-LOX-1 group and HG+LV-Con group.Cells in HG+LV-LOX-1 group and HG+LV-Con group were treated with 10 μ mol/L SB216763 and 10 μ mol/L STATTIC for 24 h,respectively,and then they were recorded as HG+LV-LOX-1+SB216763 group,HG+LV-Con+SB216763 group,HG+LV-LOX-1+STATTIC group and HG+LV-Con+STATTIC group.CCK-8 was used to detect the activity of CFs,and the expression levels of mRAN and protein of LOX-1,collagen type I(COL-I),thioredoxin 5(TXNDC5),GSK-3β,STAT3,p-GSK-3β and p-STAT3 were detected by qRT-PCR and Western blot.Results CFs infected with LOX-1 RNAi lentiviral vector were obtained,which showed green under fluorescence microscopy.Compared with HG and HG+LV-Con groups,the mRNA expressions of LOX-1,COL-I and TXNDC5 were decreased in HG+LV-LOX-1 group(P<0.05).Compared with HG+LV-LOX-1 group,mRNA expressions of COL-I and TXNDC5 were decreased in HG+LV-LOX-1+SB216763 and HG+LV-LOX-1+STATTIC groups(P<0.05).Compared with HG and HG+LV-Con groups,p-GSK-3β protein expression was increased in HG+LV-LOX-1 group(P<0.05),while LOX-1,p-STAT3,COL-I,TXNDC5 protein expression was decreased in HG+LV-LOX-1 group(P<0.05).Compared with HG+LV-LOX-1 group,p-GSK-3β protein expression was increased in HG+LV-LOX-1+SB216763 group(P<0.05),while the protein expressions of p-STAT3,COL-I and TXNDC5 were decreased in HG+LV-LOX-1+SB216763 and HG+LV-LOX-1+STATTIC groups(P<0.05).Conclusion LOX-1,GSK-3β,STAT3,TXNDC5,and COL-I are involved in high glucose induced CFs fibrosis.LOX-1 promotes the expression of TXNDC5 and COL-I through GSK-3β/STAT3 pathway,and inhibition of LOX-1 can inhibit high glucose induced CFs fibrosis.

Objective To compare the clinical outcomes of all-inside arthroscopic and open recon-struction of the anterior talofibular ligament(ATFL)and calcaneofibular ligament(CFL).Methods The clinical data of 51 patients with chronic lateral ankle instability(CLAI)and treated in our department between January 2017 and July 2021 were analyzed retrospectively.Among them,24 received ar-throscopic ATFL and CFL reconstruction(arthroscopy group),while 27 underwent conventional surgery(open group).The perioperative data including surgical time,intraoperative complications,hospitaliza-tion duration and time to resume normal walking were compared between the two groups.Moreover,postoperative CT examination was performed to evaluate the position of the bone tunnel.Before as well as 3 months,6 months,1 year,and 2 years after the operation,both groups were evaluated using the American Orthopedic Foot and Ankle Society Score(AOFAS),Karlsson score,visual analogue scale(VAS),drawer test,and inversion test.Meanwhile,the occurrence of complications was also recorded and compared.Results Both groups underwent the surgery successfully.The total length of incision and time to resume normal walking in the arthroscopy group were significantly shorter than the open group(P<0.05),while there was no significant difference between them in surgical time and hospital stay(P>0.05).Postoperative CT showed that in the arthroscopy group,1 case had suboptimal talus bone tun-nel position,while in the open group,1 had suboptimal calcaneus bone tunnel position and another suffered from suboptimal talus bone tunnel position,with the remaining bone tunnels located within the corresponding footprint area.All patients were followed up for 24 to 33 months.Significant improve-ment was observed in the average AOFAS score,Karlsson score,and VAS score in both groups after the operation(P<0.05),and both the drawer and inversion tests were of negative results.Three months postoperatively,the arthroscopic group had significantly better AOFAS,Karlsson and VAS score than the open group(P<0.05).Moreover,at 6 months postoperatively,the average AOFAS and Karlsson scores of the arthroscopy group were significantly superior to the open group(P<0.05).However,1 year and 2 years postoperatively,no significant differences were found between the two group in the AOFAS,Karlsson and VAS score(P>0.05).Moreover,no serious complications occurred during surgery and follow-up in both groups.Conclusion The efficacy of arthroscopic reconstruction of ATFL and CFL is comparable to open reconstruction in treating CLAI,with the former therapy resulting in faster recov-ery.

This review described the clinical data of 6 recipients with Legionella pneumonia after allogeneic hematopoietic stem cell transplantation (allo-HSCT) through metagenomic next generation sequencing (mNGS) from September 2019 to July 2023 at First Affiliated Hospital of Soochow University. The clinical characteristics and treatment outcomes were retrospectively examined. Legionella infection is a rare opportunistic infection after allo-HSCT. A definite diagnosis is rather difficult and an earlier diagnosis yields a better prognosis. As an early and accurate diagnostic tool for clinical practice, mNGS detection is worthy of wider applications.

Objective To explore the clinical effect of personalized pars plana vitrectomy(PPV)for proliferative di-abetic retinopathy(PDR).Methods In this retrospective case study,76 patients(86 eyes)diagnosed with PDR and re-ceiving PPV in the Department of Ophthalmology of Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine,from October 2019 to November 2022,were divided into the observation group(40 patients,46 eyes)and the control group(36 patients,40 eyes).Patients in the obseration group were treated with personalized PPV,while patients in the control group were treated with conventional PPV,After treatment,all patients were followed up for 12 months.The operation time,intraoperative use of heavy water and silicone oil,incidence of iatrogenic retinal tears and heavy water resi-dues,proportion of scleral buckling,preoperative and postoperative best corrected visual acuity(BCVA)and intraocular pressure(IOP),retinal reattachment rate at 12 months after surgery,and the incidence of post-vitrectomy vitreous hemor-rhage(PVH),diabetic macular edema(DME)and neovascular glaucoma(NVG)were compared between the two groups.Results The operation time of patients in the observation group was shorter than that in the control group(P＜0.05).Intraoperative use of heavy water and silicone oil in the observation group was lower than that in the control group(both P＜0.05).The incidence of iatrogenic retinal tears and heavy water residues and the proportion of scleral buckling showed no statistically significant difference between the two groups(all P＞0.05).There was no statistically significant difference between the two groups in BCVA preoperatively,3,6 and 12 months postoperatively(all P＞0.05).BCVA in the observa-tion group was better than that in the control group at 1 day,1 week and 1 month after surgery(all P＜0.05).Compared with the preoperative value,BCVA increased in the observation group at 1 day,1 week,1 month,3 months,6 months,and 12 months after surgery(all P＜0.05);in the control group,BCVA increased slightly at 1 day and 1 week(both P＞0.05)and then increased significantly at 1 month,3 months,6 months,and 12 months after surgery(all P＜0.05).The two groups showed no statistically significant difference in IOP at 1 day,1 week,1 month,3 months,6 months,and 12 months postoperatively(all P＞0.05).There was no statistically significant difference in the retinal reattachment rate and the inci-dence of complications such as PVH,DME,and NVG between the two groups at 12 months postoperatively(all P＞0.05).Conclusion Personalized PPV can shorten the operation time,reduce the intraoperative use of heavy water and silicone oil,enhance the efficiency of the operation,and rapidly improve the visual acuity of PDR patients.
