Objective:To investigate the impact of non-alcoholic fatty liver disease (NAFLD) on the outcome of patients with acute ischemic stroke (AIS).Methods:Patients with AIS visited the Affiliated Jiangning Hospital of Nanjing Medical University between June 2017 and December 2023 were included retrospectively. At 3 months after onset, the modified Rankin Scale was used to evaluate the outcome, with scores of 0-2 defined as good outcome and >2 defined as poor outcome. Multivariate logistic regression analysis was used to determine the impact of NAFLD on the outcome of patients with AIS. Results:A total of 143 patients with AIS were enrolled, including 95 males (66.43%), aged 67.79±11.15 years. Ninety six patients (67.13%) had good outcome, and 47 (32.87%) had poor outcome. Multivariate logistic regression analysis showed that after adjusting for confounding factors, NAFLD was independently associated with the poor outcome in patients with AIS (odds ratio 2.500, 95% confidence interval 1.015-6.161; P=0.046). Conclusion:NAFLD is an independent risk factor for poor outcome in patients with AIS.

Objective To systematically review the incidence and influencing factors of refeeding syndrome(RFS)in critically ill patients,and provide references for early identification of RFS and formulation of preventive measures.Methods Computerized searches were conducted for studies on RFS in critically ill patients in the databases of China National Knowledge Infrastructure(CNKI),Wanfang,VIP,CBM,PubMed,Embase,Web of Science,CINAHL,Cochrane Library from inception to May 29th,2024.Data analysis was performed using Stata 16.0 software.Results A total of 29 articles with 5 720 participants were included.The Meta-analysis showed that the incidence of RFS in critically ill patients was 33.68％.The subgroup analysis showed that the incidence of RFS in critically ill patients was higher in studies conducted in 2020 or later(38.22％),in the Americas(36.39％),and with only electrolyte changes as the diagnostic basis(37.51％).Risk factors for RFS in critically ill patients included higher acute physiological and chronic health evaluation Ⅱ scores(OR=1.41),higher sequential organ failure assessment scores(OR=1.29),initiation of feeding within 48 h of ICU admission(OR=3.36),age ≥60 years(OR＝2.82),diabetes mellitus(OR=3.53),pre-albumin concentration＜150 g/L(OR=5.53),albumin concentration＜30 g/L(OR=3.26),caloric intake＞25％standard calories(OR=2.86),enteral solution temperature of 36～38 ℃(OR=2.32),feeding rate＞50 ml/h(OR=3.76),fasting time ≥2 d before feeding(OR=2.46),history of alcoholism(OR=2.64).Conclusion The incidence of RFS in critically ill patients is high and there are many influencing factors.Nurses should improve their awareness and attention to RFS,accurately identify high-risk groups and risk factors,and adopt a multidisciplinary collaborative model to develop whole-course,detailed and personalized intervention measures to prevent RFS.

Objective:To investigate the efficacy and safety of the application of microwave ablation assisted clamp-less suture-less nephron sparing surgery technique in the management of cystic renal cell carcinoma.Methods:The data of 21 consecutive patients with cystic renal cell carcinoma who underwent microwave ablation assisted clamp-less suture-less laparoscopic nephron sparing surgery (MACS-LNSS) in Renji Hospital, Shanghai Jiaotong University School of Medicine from January 2017 to December 2020, were retrospectively analyzed. There were 17 males and 4 females with a mean age of (58.0±2.6) years old. There were 19 cases with Eastern Cooperative Oncology Group (ECOG) score 0 and 2 with score 1. The mean diameter of the tumor was (3.6±0.4) cm, and the mean distance from the collecting system was (10.7±0.9) mm with 12 located on the left and 9 on the right side. There were 5 cases of Bosniak Ⅲ with mean CT value (27.6±4.6) HU and 16 of Bosniak Ⅳ and the mean estimated glomerular filtration rate(eGFR) was (84.1±4.1 ) ml/(min·1.73 m 2). The American Society of Anesthesiology (ASA) graded 17 cas as grade 1, 3 cases as grade 2 and 1 cases as grade 3. MACS-LNSS was performed for all patients. The microwave ablation probe was introduced via the laparoscopic trocar and inserted into the tumor. Then all tumors were resected after microwave ablation was performed for 1 to 3 cycles lasting 2 to 5 minutes for each tumour with a power output of 60 to 100 W using an MTC-3C microwave ablation system. Results:MACS-LNSS was successfully performed in 20 cases. Another one converted to conventional laparoscopic partial nephrectomy because of intraoperative bleeding with 14 min renal artery branch clamped. No case converted to open surgery or radical nephrectomy. The mean operative time was (92.0±6.3) min, with a mean estimated blood loss of (60.0±7.2) ml. The mean length of postoperative hospital stay was (2.7±0.1) d. No case required perioperative transfusion. One case with fever and one case with urine leakage were observed postoperatively and recovered after conservative treatment. Pathologic results revealed 18 cases of clear cell carcinoma, 3 of low grade malignant potential multilocular cystic renal cell tumors. The median eGFR at 6 months postoperative was (82.9±3.8) ml/(min·1.73 m 2).No local recurrence and distant metastasis was observed with a mean follow-up of (41.3±1.5)(range from 32 to 58) months. Conclusions:MACS-LNSS which has the advantages of controllable complications is an alternative, safe and feasible technique for cystic renal cell carcinoma less than 7 cm, with regular tumor base, and the distance from the collecting system more than 5 mm.

Objective:To observe the effects of moxibustion on the levels of glucose-6-phosphate dehydrogenase(G6PD)and reduced nicotinamide adenine dinucleotide phosphate(NADPH)in the plasma and spleen and the CD4+T-cell number in the spleen of rats with adjuvant arthritis,thus to explore the mechanism in rheumatoid arthritis(RA)treatment with moxibustion by regulating the CD4+T-cell proliferation through G6PD-mediated pentose phosphate pathway. Methods:Twenty-seven male Sprague-Dawley rats were randomly divided into a blank group,a model group,and a moxibustion group,with 9 rats in each group.Incomplete Freund's adjuvant was used to induce inflammation in the model group and the moxibustion group.The blank group and the model group were not intervened.In the moxibustion group,suspended moxibustion was performed at bilateral Zusanli(ST36),Guanyuan(CV4),and Ashi points for 30 min,once a day for 24 times in total.Hematoxylin-eosin staining was used to evaluate the histopathological changes of rat synovial tissue;the swelling degree of the rat toes was observed by measuring the toe volume;G6PD and NADPH in the spleen and plasma were detected by Western blotting and enzyme-linked immunosorbent assay.Flow cytometry was used to detect the CD4+T-cell number in the spleen. Results:Compared with the blank group,the levels of G6PD and NADPH in the plasma and spleen and the CD4+T-cell number in the spleen were significantly increased in the model group(P<0.01 or P<0.05).Compared with the model group,the NADPH level in the spleen and plasma and the CD4+T-cell number in the spleen in the moxibustion group decreased significantly(P<0.05 or P<0.01),and the G6PD level in the plasma decreased significantly(P<0.05),but there was no significant difference in the G6PD level in the spleen(P>0.05). Conclusion:Moxibustion can regulate immunity and improve joint synovial inflammation in RA.The mechanism may be that the G6PD-mediated pentose phosphate pathway reduces the production of metabolite NAPDH in CD4+T cells,thereby inhibiting the proliferation of naive CD4+T cells.

Purpose To evaluate the value of shear wave elastic imaging of liver and spleen in predicting high risk esophageal and gastric varices in cirrhosis.Materials and Methods Sixty-four patients with cirrhosis in the First Hospital of Lanzhou University from November 2019 to April 2022 were enrolled prospectively,and underwent gastroscopy,elastography and serological examination.According to gastroscopy,patients were divided into high-risk varices(HRV,30 cases)and non-HRV group(34 cases),the differences of each clinical index and shear wave elastic imaging parameter between the groups were compared.The diagnostic efficacy of liver and spleen stiffness measurement for HRV was analyzed.And the diagnostic models were established for exploring the diagnostic effectiveness of different models with respect to excluding HRV in compensated liver cirrhosis.Results There were significant differences in platelet[(74±24)×109/L vs.(124±50)×109/L],liver stiffness[(16.1±5.6)kPa vs.(13.6±5.5)kPa]and spleen stiffness[(41.7±8.9)kPa vs.(28.1±8.6)kPa]between HRV and non-HRV groups(t/Z/χ2=5.136,-1.832,-6.206,all P<0.05).The areas under the curve of liver stiffness and spleen stiffness for predicting HRV were 0.660 and 0.858,respectively.The Baveno Ⅵ combined with the spleen stiffness model had the best performance(30.0％)for excluding HRV.Conclusion The measurement of liver and spleen stiffness by shear wave elastography has great diagnostic value for predicting HRV in cirrhosis,and spleen stiffness is better than liver stiffness.

Objective:To analyze the expression level of hepcidin in urine of patients with type 2 diabetic kidney disease (DKD) in different stages and its relationship with DKD and related indicators.Methods:From June 2022 to December 2023, 139 inpatients with type 2 diabetes mellitus in the Department of Endocrinology, Zhoupu Hospital Affiliated to Shanghai Health Medical College were selected as the research objects. The stage of DKD was judged by urinary albumin/creatinine ratio (UACR): UACR <30 mg/g in stage A1, UACR ≥30 mg/g~≤300 mg/g in stage A2. DKD in stage A3 was UACR >300 mg/g. According to the stage of DKD, there were 50 patients with stage A1 (group A1), 47 patients with stage A2 (group A2), and 42 patients with stage A3 (group A3). Urinary hepcidin was determined by enzyme-linked immunosorbent assay, and fasting blood glucose, total cholesterol, triglyceride, alanine aminotransferase (ALT), serum creatinine and hemoglobin A1c (HbA1c) were measured and compared. The correlation between urinary hepcidin and other markers, the risk factors of DKD and the evaluation of diagnostic value were analyzed. Measurement data with normal distribution were expressed as xˉ± s, mean comparison among the three groups, if the variance was homogeneous, the analysis of variance test was used; if the variance was not homogeneous, the Welch test was used; the proportion or rate of enumeration data among the groups was tested by χ2 test; Pearson correlation analysis was used for correlation analysis; binary Logistic regression model was used for multivariate analysis; The value of urinary hepcidin in the diagnosis of DKD was analyzed by receiver operating characteristic curve. Results:Urinary hepcidin was (5.3±1.0) μg/L in group A1, (7.7±2.5) μg/L in group A2, and (10.1±2.7) μg/L in group A3. There was significant difference among the three groups ( F=58.92， P<0.001), and urinary hepcidin increased with the severity of DKD; Urinary Hepcidin was related to UACR ( R=0.684, P<0.001), serum creatinine ( R=0.590, P<0.001), course of disease ( R=0.485, P<0.001), triglyceride ( R=0.264, P=0.002), age ( R=0.235, P<0.001), P=0.005), total cholesterol ( R=0.224, P=0.008), systolic pressure ( R=0.194, P=0.022), glomerular filtration rate ( R=-0.540, P<0.001) and BMI ( R=-0.175, P=0.040); There was no correlation with fasting blood glucose, HbA1c, ALT and diastolic blood pressure (all P>0.05). Secondly, the increase of urinary hepcidin level was a risk factor for DKD by binary Logistic regression analysis ( OR=4.147,95% CI: 2.154-7.984, P<0.001). Finally, receiver operating characteristic curve analysis showed that the optimal cut-off point of urinary hepcidin was 6.35 μg/L, with a sensitivity of 0.831 and a specificity of 0.880. Conclusion:Urinary hepcidin increases with the severity of DKD, which may be a biomarker for early diagnosis of DKD.

Radiotherapy (RT) can potentially induce systemic immune responses by initiating immunogenic cell death (ICD) of tumor cells. However, RT-induced antitumor immunologic responses are sporadic and insufficient against cancer metastases. Herein, we construct multifunctional self-sufficient nanoparticles (MARS) with dual-enzyme activity (GOx and peroxidase-like) to trigger radical storms and activate the cascade-amplified systemic immune responses to suppress both local tumors and metastatic relapse. In addition to limiting the Warburg effect to actualize starvation therapy, MARS catalyzes glucose to produce hydrogen peroxide (H₂O₂), which is then used in the Cu⁺-mediated Fenton-like reaction and RT sensitization. RT and chemodynamic therapy produce reactive oxygen species in the form of radical storms, which have a robust ICD impact on mobilizing the immune system. Thus, when MARS is combined with RT, potent systemic antitumor immunity can be generated by activating antigen-presenting cells, promoting dendritic cells maturation, increasing the infiltration of cytotoxic T lymphocytes, and reprogramming the immunosuppressive tumor microenvironment. Furthermore, the synergistic therapy of RT and MARS effectively suppresses local tumor growth, increases mouse longevity, and results in a 90% reduction in lung metastasis and postoperative recurrence. Overall, we provide a viable approach to treating cancer by inducing radical storms and activating cascade-amplified systemic immunity.

As a new type of immunosuppressant，iguratimod can mediate the anti-inflammatory signaling pathway by inhibiting the proliferation of inflammatory cells and reducing the release of inflammatory cytokines， and play the role of anti-inflammatory. It can affect the proliferation of immune cells and the expression of immune factors，reduce the production and deposition of immune complexes in the body，and play the role of immune regulation. It can regulate bone metabolism by mediating signaling pathways such as Wnt/β-catenin，Toll-like receptor 4/nuclear factor-κB and osteoprotegerin/nuclear factor-κB receptor activating factor ligand， and play a role in bone protection. It can inhibit pulmonary fibrosis by inhibiting the expression of transforming growth factor β1/ Smad2/3 signaling pathway，tumor necrosis factor-α，interleukin-1，interleukin-6，matrix metalloproteinase-9 and other inflammatory cytokines in lung tissue，and inhibiting the expression of collagen and fibronectin. Its efficacy and safety have been confirmed in the clinical application of rheumatoid arthritis and primary Sjogren syndrome and included in the diagnosis and treatment of the disease. It has also shown good efficacy in the clinical application of other connective tissue diseases such as systemic lupus erythematosus and ankylosing spondylitis，and no obvious safety risks have been found.

Objective:To investigate the correlation of the emm genotypes and virulence genes with the isolation sites of Group A Streptococcus (GAS). Methods:It was a retrospective study.The specimens were collected from children with impetigo in Beijing Children′s Hospital, Capital Medical University from 2006 to 2008 for GAS isolation and identification.A total of 24 GAS strains were isolated from 16 children with impetigo, among which 7 pairs of strains were isolated from the throat and skin of 7 children, and 1 pair of strains was isolated from the vulva and skin of one child, and the remaining 8 GAS strains were isolated from the skin pus samples of 8 children.Polymerase chain reaction was applied to detect the emm genotypes and 13 virulence genes ( speA, speB, speC, speF, speG, speH, speI, speJ, speK, speL, speM, smeZ and ssa). The correlation of the emm genotypes and virulence genes with the isolation sites of GAS strains was analyzed. Results:In this study, four emm genotypes were detected, including emm1.0 (15/24), emm12.0 (4/24), emm22.0 (2/24) and emm160.0 (1/24), and one subtype emm12.19 (2/24) was detected as well.The carrying rates of 13 virulence genes speA, speB, speC, speF, speG, speH, speI, speJ, speK, speL, speM, smeZ and ssa were 58.3%, 100%, 91.7%, 100%, 50.0%, 12.5%, 54.2%, 66.7%, 16.7%, 25.0%, 12.5%, 100% and 91.7%, respectively.All strains carried 5 to 11 virulence genes and they all carried speB, speF and smeZ.There were significant differences in the carrying rate of speA and speJ among the strains with different emm genotypes (all P<0.05). There was no significant difference in the distribution of virulence genes between skin isolates and pharyngeal isolates, including the 5 pairs of strains carrying the emm1.0 genotype (all P>0.05). Conclusions:The distribution of virulence gene of GAS in children with impetigo is significantly correlated with the emm genotype, rather than the isolation site.
