ObjectiveTo explore the clinical characteristics and risk factors for 30-day mortality in hospitalized patients with bloodstream infections (BSI) caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). MethodsData were obtained retrospectively from the electronic medical records of inpatients at a tertiary A-grade hospital in Shanghai from January 2016 to December 2023. The collected variables included age, gender, department, surgical treatment, empirical antibiotic therapy, Pitt Bacteremia score (PBS), Charlson comorbidity index (CCI), INCREMENT-CPE score (ICS), length of hospital stay, the time from CRKP-BSI to discharge and, etc. The follow-up period ended upon discharge, with the follow-up outcomes defined as in-hospital mortality or discharge. The endpoint was defined as death within 30 days (including day 30) caused by CRKP-BSI or infection-related complications. Patients who survived within 30 days after CRKP-BSI were classified into the survival group, while those who died within 30 days were classified into the death group. Independent risk factors for 30-day mortality in patients with CRKP-BSI were analyzed using univariate and multivariate Cox regression analysis. ResultsA total of 71 hospitalized patients with CRKP-BSI, comprising 51 males and 20 females, with an average age of (65.12±18.25) years, were included during the study period. The M (P₂₅, P₇₅) of hospital stay were 37.00 (24.00, 56.00) days, and M (P₂₅, P₇₅) of the duration from CRKP-BSI to discharge or death were 18.00 (7.00, 35.00) days. There were 20 deaths (28.17%) in the death group and 51 survivors (71.83%) in the survival group. The results of multivariate Cox regression analysis showed that the ICS as an independent risk factor for 30-day mortality in CRKP-BSI patients (HR=1.379, 95%CI: 1.137‒1.671, P=0.001). Each 1-point increase in the ICS was associated with a 37.9% increase in the risk of mortality. ConclusionThe ICS is found to be a risk factor for 30-day mortality in patients with CRKP-BSI, which may facilitate the prediction for the risk of 30-day mortality and thereby support clinical decision-making for patients with CRKP-BSI.

Maturity-onset diabetes of the young (MODY) is a special type of diabetes characterized by clinical features including early onset of diabetes (before 30 years of age), autosomal dominant inheritance, impaired glucose-induced insulin secretion, and hyperglycemia. So far, 14 types of MODY have been reported, accounting for about 1%-5% of the patients with diabetes. MODY often presents with an insidious onset, and although 14 subtypes have been identified for MODY, it is frequently misdiagnosed as type 1 or type 2 diabetes due to overlapping clinical features and high costs and limitations of genetic testing. This article reviews the clinical features of MODY subtypes in order to improve the accuracy of the diagnosis and treatment of MODY.

OBJECTIVE: To determine the prevalence of lumbar spondylolysis (LS) and the proportion of spondylolytic spondylolisthesis (SS) in China, and to evaluate the musculoskeletal status of patients with LS and SS. METHODS: Spine Computed Tomography (CT) images were collected from community populations aged 40 and above in a nationwide multi-center project. LS was diagnosed, and SS was graded by an experienced radiologist. Bone mineral density (BMD) and paraspinal muscle parameters were quantified based on CT images. RESULTS: One hundred and seventeen patients of a total of 3,317 individuals were diagnosed with LS, corresponding to a prevalence rate of 3.53%. 63 of the 1,214 males (5.18%) and 54 of the 2,103 females (2.57%) were diagnosed with LS. SS occurred in 64/121 vertebrae (52.89%). BMD was not associated with LS ( P = 0.341). The L5 extensor paraspinal muscle density was higher in the LS group than in the non-LS group. In the LS group, patients with SS had a smaller L5 paraspinal extensor muscle cross-sectional area than those without SS ( P = 0.003). CONCLUSION The prevalence of LS in Chinese adults was 3.53%, with prevalence rates of 5.18% in males and 2.57% in females. Patients with LS have higher muscle density, whereas those with SS have smaller muscle cross-sectional areas at the L5 level.

Aim To express and purify recombinant hCGH-CTP fusion protein in high-density suspension culture of Chinese hamster ovary cells (CHO-S), and to verify the lipid accumulation effect of rhCGH-CTP on 3T3-L1 mature adipocytes. Methods The recombinant protein expression vector (pcDNA3. 1-rhCGH-CTP) was constructed, achieved by fusing the human glycoprotein hormone beta 5/alpha 2 cDNA with CTP Linker. The expression plasmid was transiently transfected into the suspended CHO-S to express rhCGH-CTP protein and then purified, and the protein biological activity was verified. Intervention with 3T3-L1 mature adipocyte cells for 24 h was performed to detect the changes of intracellular triglyceride (TG) level. Results Western blot results showed that rhCGH-CTP protein was successfully expressed in CHO-S cells, and the yield was up to 715. 4 mg • L~ . The secreted protein was purified by AKTA pure system with higher purity that was up to 90% as identified by SDS-PAGE. In addition, the intracellular cAMP content of mature adipocytes with high expression of TSHR gene significantly increased after intervention with different concentrations of rhCGH-CTP protein by ELISA kit, indicating that rhCGH-CTP protein had biological activity. Oil red 0 staining showed that compared with the control group, the lipid content of mature adipocytes in the intervention groups with different concentrations of rhCGH-CTP protein significantly decreased (P < 0. 05) . Conclusions The rhCGH-CTP protein has been successfully expressed and purified with biological activity, and effectively reduce TG. This research provides an important theoretical basis for further revealing the physiological role of CGH protein and its potential application in clinical practice.

Objective To observe the value of quantitative analysis technique for evaluating left atrial function in children with Kawasaki disease(KD).Methods Totally 43 children with KD(KD group)who would undergo intravenous immunoglobulin(IVIG)therapy were prospectively enrolled,including 23 with(ectasia subgroup)and 20 without coronary artery ectasia(non-ectasia subgroup),while 50 healthy children were enrolled as control group.Children in KD group.Echocardiography was performed in acute phase(10-12 hours before IVIG therapy),subacute phase(1 week after therapy)and convalescent phase(6-10 weeks after therapy)of KD.The left atrial reservoir strain(LASr),early diastolic conduit strain(LAScd),late diastolic contractile strain(LASct),left ventricular global longitudinal strain(LVGLS),basal segment,middle segment and apical segment longitudinal strain(LS)were measured.Strain parameters of different periods were compared between groups and subgroups in KD group,and left atrial strain parameters in KD subgroup were compared among different periods.Pearson correlation analysis was used for evaluation of the correlations of left atrium and left ventricle strain parameters in children with acute KD.Results LASr,LAScd,LASct,LVGLS and left ventricular segment LS of KD group in acute and subacute phase were all lower than those of control group(all P＜0.05),while the basal segment LS of KD group in convalescent phase was lower than that of control group(P＜0.05).In KD group,compared with acute stage,LASr,LAScd,LASct,LVGLS and left ventricular segment LS significantly increased in subacute phase(all P＜0.05),while in convalescent phase,LASr,LAScd,LASct,LVGLS,middle segment LS and apical LS further increased(all P＜0.05).LASr and LAScd in acute phase of KD group were positively correlated with LVGLS,middle segment LS and apical segment LS(r=0.43-0.67,all P＜0.05).In the acute and subacute phases,no significant difference of left artial LS parameters was found between subgroups within KD group(all P＞0.05).LASr and LAScd in convalescent phase of ectasia subgroup were lower than those of non-ectasia subgroup(all P＜0.05),while no significant difference of LASct was found between subgroups within KD group(P＞0.05).Conclusion Quantitative analysis technique could be used to evaluate left atrial function in KD children.Changes of left atrial function in KD children were closely related to left ventricular systolic function,which was affected by coronary artery ectasia in convalescent phase.

Acute myocardial infarction (AMI) has become the leading cause of death in cardiovascular diseases. Myocardial ischemia and reperfusion (MI/R) occurs when myocardial blood circulation is reconstructed after blood supply is limited or lack, often after myocardial infarction, and is the main cause of acute myocardial injury. According to the length of ischemia time, arrhythmia, myocardial inhibition, and myocardial infarction may occur in sequence in MI/R. Mitochondria are the key organelles involved in MI/R injury. Mitochondrial ROS eruption, Ca²⁺ imbalance, mPTP opening, mitochondrial swelling, and release of pro-apoptotic proteins all lead to mitochondrial dysfunction and myocardial function impairment. Exercise is an effective intervention to prevent myocardial ischemia-reperfusion injury, and its protective effect is closely related to the intensity of exercise, the length of exercise time, the type of exercise and the internal exercise ability. The mitochondrial mechanism of exercise protection against myocardial ischemia-reperfusion injury is determined by many factors. During reperfusion, the heart after trained is better able to maintain energy homeostasis, maintain ΔΨ_m and limit mPTP activation, maintain ATP synthesis. Activation of the sarcoK_ATP and/or mitoK_ATP channels by exercise induces cellular and/or myocardial hyperpolarization, protecting the mitochondria and myocardium during MI/R. Exercise-trained hearts can regulate calcium homeostasis during MI/R and limit mitochondrial Ca²⁺ overload. Exercise training can improve the activity of mitochondrial antioxidant enzymes to clear ROS and regulate mitochondrial Ca²⁺ concentration during MI/R. Exercise can increase the bioavailability of NO near mitochondria and indirectly achieve exercise-induced myocardial protection through protein S-nitrosylation and the eNOS-NO pathway is related to mitochondrial biogenesis after exercise training. Exercise training can also affect mitochondrial dynamics during MI/R by preventing mitochondrial division and promoting mitochondrial fusion. Exercise training can promote autophagy of damaged mitochondria and reduces apoptosis through mitochondria too, thus helping to maintain the function of mitochondrial bank. Besides these, exercise training leads to the production of motor factors (mainly from the muscles, but also from the brain, red blood cells, and other tissues) that contribute to remote regulation of the heart. This paper reviews the mitochondrial mechanism of MI/R, the protective effect of exercise on MI/R and the role of mitochondria in it, in order to provide more theoretical basis and new therapeutic targets for the diagnosis and treatment of heart disease, and provide new targets for drug research and development. In future clinical treatment, it is expected that sports pills targeted mitochondria can treat MI/R injury for bedridden people who cannot exercise or people who do not want to exercise through new technological means such as nanoparticle packaging.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.
