OBJECTIVE: To analyze the efficacy and access safety of extracorporeal membrane oxygenation (ECMO) in series with continuous renal replacement therapy (CRRT) access for critically ill patients using propensity score matching analysis, and to explore the potential influencing factors of infection. METHODS: A total of 200 critically ill patients who received both ECMO and CRRT treatment in the intensive care unit (ICU) of Huai'an Second People's Hospital from December 2020 to December 2024 were retrospectively selected as the research subjects. They were divided into the independent operation group (72 cases) and the series system group (128 cases) according to the access connection mode of ECMO and CRRT. Propensity score matching analysis was used to perform 1 : 1 matching for patients of the two groups. The general data [age, gender, body mass index (BMI), clinical diagnosis, underlying disease, intubation method, intubation position, disease severity, ECMO support duration, catheter indwelling duration, oxygenation index (PaO₂/FiO₂) at 48 hours after ECMO initiation, serum creatinine (SCr), procalcitonin (PCT), hemoglobin (Hb), white blood cell count (WBC), platelet count (PLT)], treatment status [ECMO initiation duration, ECMO operation duration, ECMO flow, left ventricular ejection fraction (LVEF), CRRT initiation duration, CRRT catheter indwelling duration, inflow and outflow volume of replacement fluid], clinical outcome indicators (28-day survival rate, length of ICU stay, renal function recovery, fluid balance compliance rate), and access safety indicators (incidence of ECMO access thrombosis, incidence of infection, and incidence of bleeding events) of all the patients were collected. Subgroup analysis was conducted based on the occurrence of infection, and multivariate Logistic regression analysis was used to screen the potential risk factors for infection in critically ill patients receiving both ECMO and CRRT treatment. RESULTS: Finally, a total of 120 patients were successfully matched, with 60 patients in both the independent operation group and the series system group. No statistically significant differences were observed in the general data between the two groups, indicating comparability. Compared with the independent operation group, the ECMO flow at 48 hours after ECMO initiation, SCr, and alanine transaminase (ALT) of the patients in the series system group were significantly decreased, while the LVEF at 48 hours after ECMO initiation was significantly increased, additionally, the CRRT initiation duration, CRRT catheter indwelling duration, and the length of ICU stay were significantly shortened, and the inflow and outflow volume of replacement fluid were significantly increased. The incidence of infection and bleeding events in the series system group was significantly lower than that in the independent operation group [infection incidence: 11.67% (7/60) vs. 36.67% (22/60), bleeding event incidence: 8.33% (5/60) vs. 48.33% (29/60), both P < 0.05]. No significant difference was found in the other general data, treatment status, clinical outcome indicators, or access safety indicators between the two groups. Among the 120 patients, 29 cases developed infection (accounting for 24.17%), and 91 cases had no infection (accounting for 75.83%). Compared with the non-infection group, the catheter indwelling duration was significantly prolonged and PCT was significantly increased in the infection group, while the PLT and the proportion of patients with ECMO and CRRT access connected via the series system were significantly decreased. Multivariate Logistic regression analysis showed that catheter indwelling duration [odds ratio (OR) = 1.277, 95% confidence interval (95%CI) was 1.001-1.629, P = 0.049], PCT (OR = 1.529, 95%CI was 1.222-1.914, P < 0.001], PLT (OR = 0.953, 95%CI was 0.926-0.981, P = 0.001), and access connection mode (OR = 0.289, 95%CI was 0.090-0.930, P = 0.037) were potential risk factors for infection in critically ill patients. CONCLUSIONS The ECMO-in-series CRRT access can accelerate the initiation of CRRT, avoid local bleeding, stabilize patients' cardiac, hepatic and renal functions, reduce potential infection risks, and improve the prognosis of patients.

Objective:To explore the medication law of TCM external therapy for the treatment of diabetic foot using data mining methods.Methods:Literature on TCM external treatment for diabetic foot was retrieved from CNKI, Wanfang Data, and Chongqing VIP from the establishment of the databases to June 30, 2024. Excel 2019 software was used to conduct frequency statistics on drug frequency, properties, tastes and meridian tropism, drug efficacy, and commonly used drug pairs. Ancient and Modern Medical Cases Cloud Platform V3.5 was used for association rules, and SPSS Statistics 27.0 was used for complex network analyses.Results:A total of 425 articles were included, involving 328 prescriptions and 232 drugs. The drugs with higher frequency were Carthami Flos, Angelicae Sinensis Radix, Cinnamomi Ramulus, Olibanum, etc. The main tastes were pungent, bitter, and sweet; the main properties were cold and warm; the main meridians were heart, spleen, and liver meridians. The main efficacy was promoting blood circulation and removing blood stasis, clearing heat, and tonifying deficiency; association rule analysis obtained 20 commonly used drug pairs; clustering analysis resulted in four core drug combinations; complex network analysis led to one core prescription.Conclusions:TCM external therapy for diabetic foot follows the guiding principles of "promoting blood circulation and unblocking collaterals, tonifying deficiency and clearing heat" with coordinated regulation of the "heart-liver-spleen meridians". The core prescription and stage-specific formulation strategies reflect a trinity diagnostic and therapeutic approach of "disease differentiation-syndrome differentiation-stage differentiation", providing valuable reference and insights for clinical prescription practices.

Background:Following the short-term outbreak of coronavirus disease 2019(COVID-19)in December 2022 in China,clinical data on kidney transplant recipients(KTRs)with COVID-19 are lacking.Methods:We conducted a single-center retrospective study to describe the clinical features,complications,and mortality rates of hospitalized KTRs infected with COVID-19 between Dec.16,2022 and Jan.31,2023.The patients were followed up until Mar.31,2023.Results:A total of 324 KTRs with COVID-19 were included.The median age was 49 years.The median time between the onset of symptoms and admission was 13 d.Molnupiravir,azvudine,and nirmatrelvir/ritonavir were administered to 67(20.7%),11(3.4%),and 148(45.7%)patients,respectively.Twenty-nine(9.0%)patients were treated with more than one antiviral agent.Forty-eight(14.8%)patients were treated with tocilizumab and 53(16.4%)patients received baricitinib therapy.The acute kidney injury(AKI)occurred in 81(25.0%)patients and 39(12.0%)patients were admitted to intensive care units.Fungal infections were observed in 55(17.0%)patients.Fifty(15.4%)patients lost their graft.The 28-d mortality rate of patients was 9.0%and 42(13.0%)patients died by the end of follow-up.Multivariate Cox regression analysis identified that cerebrovascular disease,AKI incidence,interleukin(IL)-6 level of>6.8 pg/mL,daily dose of corticosteroids of>50 mg,and fungal infection were all associated with an increased risk of death for hospitalized patients.Conclusions:Our findings demonstrate that hospitalized KTRs with COVID-19 are at high risk of mortality.The administration of immunomodulators or the late application of antiviral drugs does not improve patient survival,while higher doses of corticosteroids may increase the death risk.

There is currently a huge worldwide demand for donor kidneys for organ transplantation. Consequently, numerous marginal donor kidneys, such as kidneys with microthrombi, are used to save patients' lives. While some studies have shown an association between the presence of microthrombi in donor kidneys and an increased risk for delayed graft function (DGF) (McCall et al., 2003; Gao et al., 2019), other studies have demonstrated that microthrombi negatively impact the rate of DGF (Batra et al., 2016; Hansen et al., 2018), but not graft survival rate (McCall et al., 2003; Batra et al., 2016; Gao et al., 2019). In contrast, Hansen et al. (2018) concluded that fibrin thrombi were not only associated with reduced graft function six months post-transplantation but also with increased graft loss within the first year of transplantation. On the other hand, Batra et al. (2016) found no significant differences in the DGF rate or one-year graft function between recipients in diffuse and focal microthrombi groups. To date, however, the overall influence of donor kidney microthrombi and the degree of influence on prognosis remain controversial, necessitating further research.

Objective:To explore the influencing factors of acute rejection (AR) within one year after pediatric kidney transplantation (KT) and the effect of AR onset time on prognosis.Methods:From January 2011 to October 2021, a total of 112 patients aged under 18 years at the time of transplantation were selected.After excluding 6 of them with early renal non-function caused by non-rejection, 106 cases were examined.There were 63 males and 43 females with the age of 15(12, 16) years.The donors were living related (n=26) and deceased (n=80).According to the presence/absence and onset time of AR, they were assigned into three groups of AR within one year, AR after one year and non-AR.The relevant clinical data of donor/recipient, influencing factors of AR and therapeutic outcomes of AR were retrospectively compared.One-way ANOVA or Kruskal-Wallis test was utilized for comparing 1-year renal function after the occurrence of AR among three groups.With graft-function loss as an end-point event of follow-up, the effects of AR within one year and AR after one year on survival rate and function of graft-kidney were analyzed by Kaplan-Meier survival curve.Results:The median follow-up period of 106 pediatric KT recipients was 35 months.During follow-ups, 19 episodes of AR occurred in 17(16.0%) patients and 89 recipients exhibited no AR episode by the end of follow-up (non-AR group).As for initial AR, 9 episodes of AR occurred within one year (AR within one year group) and 8 episodes of AR after one year (AR after one year group).After anti-rejection treatment, 8 patients (47.1%) achieved full recovery and 6 patients (35.3%) failed to completely normalize and 3 patients (17.6%) developed graft failure.Univariate analysis indicated that, as compared with non-AR group, female recipients, donors aged under 8 years and early postoperative infection with parvovirus B19 were risk factors of AR within one year ( P=0.032, P=0.039, P=0.047).Kaplan-Meier survival analysis revealed that the incidence rates of AR within one year in patients with donors aged under 8 years and early postoperative parvoviral infection were 14.5%(8/55) and 30.0%(3/10) respectively.They were significantly higher than 2.0%(1/51) and 6.3%(6/96) of patients with donors aged above 8 years and those without parvoviral infection ( P=0.012, P=0.004).With graft-function loss as an end-point event of follow-up, Kaplan-Meier survival analysis showed that 10-year kidney graft survival rate in AR within one year and AR after one year groups were 88.9% and 65.6%.Both were significantly lower than that in non-AR group (98.9%).And the inter-group differences were statistically significant ( χ2=4.286, P=0.038; χ2=7.787, P=0.005).However, no significant difference existed in survival rate between AR within one year and AR after one year groups ( P=0.689).One-way ANOVA and Kruskal-Wallis test indicated that estimated glomerular filtration rates at 3/6/12 months after an onset of AR in AR within one year group were (76.8±51.6), (80.6±56.6) and (85.6±40.2) ml·min -1·1.73 m -2.The values of 3/6 months were lower than (125.3±39.2) and (124.7±38.2) ml·min -1·1.73 m -2 in AR after one year group.And the inter-group differences were statistically significant ( P=0.021, P=0.039).The values of 3/6/12 months were lower than (112.2±34.2), (115.3±33.2) and (117.4±30.2) ml·min -1·1.73 m -2 in non-AR group.And the inter-group differences were also statistically significant ( P=0.019, P=0.020, P=0.020). Conclusions:Female recipients, donors aged under 8 years and early postoperative infection with parvovirus B19 may elevate the risks of AR in children within one year of KT.AR within one year affects the survival rate of graft-kidney and renal function.

Obesity is increasingly prevalent globally, searching for therapeutic agents acting on adipose tissue is of great importance. Equisetin (EQST), a meroterpenoid isolated from a marine sponge-derived fungus, has been reported to display antibacterial and antiviral activities. Here, we revealed that EQST displayed anti-obesity effects acting on adipose tissue through inhibiting adipogenesis in vitro and attenuating HFD-induced obesity in mice, doing so without affecting food intake, blood pressure or heart rate. We demonstrated that EQST inhibited the enzyme activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), a therapeutic target of obesity in adipose tissue. Anti-obesity properties of EQST were all offset by applying excessive 11β-HSD1's substrates and 11β-HSD1 inhibition through knockdown in vitro or 11β-HSD1 knockout in vivo. In the 11β-HSD1 bypass model constructed by adding excess 11β-HSD1 products, EQST's anti-obesity effects disappeared. Furthermore, EQST directly bond to 11β-HSD1 protein and presented remarkable better intensity on 11β-HSD1 inhibition and better efficacy on anti-obesity than known 11β-HSD1 inhibitor. Therefore, EQST can be developed into anti-obesity candidate compound, and this study may provide more clues for developing higher effective 11β-HSD1 inhibitors.

A 55-year-old male patient with a history of hypertension and type 2 diabetes mellitus received sodium phosphates oral solution 45 ml diluted in 750 ml or more warm water in 2 divided doses for bowel cleansing on the night before and the morning of the day of colonoscopy. After the colonoscopy, the patient developed abdominal distension. Eighteen days after the colonoscopy, elevated serum creatinine (Scr) was found with a peak value of 175 μmol/L. Thirty-five days after the colonoscopy, Scr was 168 μmol/L and the glomerular filtration rate calculated by the plasma-creatinine-based equations Chronic Kidney Disease Epidemiology Collaboration was 38.54 ml/min. Renal puncture and pathological examination showed tubular epithelial cell injury with calcium phosphate deposits, and acute phosphate nephropathy was diagnosed. The patient was advised to drink more water and was given symptomatic treatments such as diuretic furosemide. Five months later, the Scr recovered to 105 μmol/L.

Objective:To explore the clinical prognosis of early endarteritis (within 2 weeks) and late endarteritis (after 2 weeks) after renal transplantation.Methods:A total of 81 cases with higher creatinineand receiving renal biopsy after renal transplantation were recruited from September 2001 to December 2014. They were divided into early endarteritis group (n=43) and late endarteritis group (n=38). Baseline profiles, serum creatine, glomerular filtration rate (GFR) before and after treatment, steroid resistance, reversal rate, graft loss and survival rate were analyzed for two groups.Results:Early endarteritis group showed worse serum creatine and GFR than late endarteritis group before rejection. Early endarteritis group had a higher rate of treatment with steroid plus antibody (86 %) than that of late endarteritis group (86 %vs.18.6 %, P<0.05). No significant inter-group difference existed in graft loss (23.3 % vs.10.5 %, P=0.131). The survival curve of transplanted kidney showed no significant inter-group difference insurvival time. Conclusions:The status of patients with early simple endothelitis is significantly worse than that of those with late simple endothelitis. However, after active treatments, the prognosis of patients with early simple endothelitis is not inferior to that of those with late simple endothelitis.
