Objective:To explore the influence of hypercholesterolemia on the risk of chronic kidney disease (CKD) in the middle-aged and elderly population and the gender differences.Methods:The data came from the "Epidemiological Survey of Chronic Kidney Disease among Adults in Urban Communities in Henan Province". The subjects came from 20 communities in Henan Province, aged ≥45 years old. Groups were based on the quartile of total blood cholesterol level and gender. Multivariate logistic regression and Cochran-Armitage trend test were used to analyze the effect of hypercholesterolemia on the risk of CKD and its gender differences.Results:A total of 4 779 subjects were enrolled into the study, with 1 934 males (40.5%) and 2 845 females (59.5%). The age was (61.3±7.7) years old and the blood cholesterol was (5.0±1.0) mmol/L. The prevalence rates of hypercholesterolemia, albuminuria, and reduced estimated glomerular filtration rate (eGFR) were 10.7%(305/2 845), 6.4%(182/2 845) and 2.8%(79/2 845) in females and 12.7%(245/1 934), 6.9%(133/1 934) and 2.3%(45/1 934) in males respectively. Compared with Q1 group, the prevalence of reduced eGFR in females were higher in Q2 and Q4 groups (both P<0.05). Among males, the prevalence of albuminuria and reduced eGFR increased with increasing blood cholesterol quartile (Cochran-Armitage trend test Z=12.231, 8.862, both P<0.001). Multivariate logistic regression analysis showed that hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR ( OR=1.49, 95% CI 1.08-2.07, P=0.016 and OR=1.65, 95% CI 1.03-2.65, P=0.037, respectively). In subgroup analysis of different genders, female hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR, while male hypercholesterolemia was not an independent influencing factor ( OR=1.54, 95% CI 0.96~2.46, P=0.075; OR=1.89, 95% CI 0.93-3.89, P=0.082, respectively). Further subgroup analysis based on the interquartile range of serum cholesterol levels found that female hypercholesterolemia was an independent influencing factor for reduced eGFR in the Q2 and Q4 groups ( OR=2.35, 95% CI 1.29-7.61, P=0.003; OR=2.51, 95% CI 1.38-8.39, P=0.001). In males, hypercholesterolemia was an independent influencing factor for albuminuria in the Q2, Q3 and Q4 groups ( OR=1.80, 95% CI 1.01-3.41, P=0.047; OR=1.85, 95% CI 1.02-3.35, P=0.044; OR=2.33, 95% CI 1.33-4.33, P=0.002). Conclusions:Hypercholesterolemia is an independent risk factor for CKD in middle-aged and elderly population, and there are gender differences, which provides a new idea for clinical prevention and control of CKD.

Acute Stanford type A aortic dissection with important branches involved is more complex, could lead to organ malperfusion syndrome even organ failure. The understanding of pathological anatomy, classification, staging, and the pathophysiological change has increasingly mature, but not complete. In addition, the treatment strategy for complex lesions is diversified, some questions may not reach consensus. Fully understanding of the anatomical and pathophysiology is very important for surgeons to choose reasonable treatment strategy. As the rapid development of the basic research, imaging techniques and the concept of surgery procedures, the manage technique of Stanfrod type A dissection and branch vessels at the same time is getting seriously, the related issues also need further discussions.

Objective: To investigate the risk factors of clinically diagnosed acute kidney injury (AKI) patients progressing to acute kidney disease (AKD). Methods: The clinical data of AKI patients admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2018 to December 31, 2018 were retrospectively analyzed. According to the outcome of the patients, AKI patients were divided into non-acute kidney disease (NAKD) group and AKD group. Clinical characteristics and laboratory data of two groups were compared. The risk factors of AKD in patients with AKI were analyzed by logistic regression, and then the receiver operating characteristic curve (ROC) was drawn to evaluate the predictive value of these risk factors. Results: A total of 254 patients with AKI were enrolled, and 186 patients developed AKD with an incidence of 73.2%. The incidences of AKD in stage 1, stage 2 and stage 3 of AKI were 20.0%, 46.7% and 83.5% respectively. Multivariate logistic regression analysis showed increased peak serum creatinine (within 7 days after AKI diagnosis) (OR=2.561, 95% CI 1.584-4.140, P<0.001), proteinuria (OR=2.952, 95% CI 1.162-7.500, P=0.023) and increased intact parathyroid hormone (OR=1.757, 95%CI 1.104-2.797, P=0.017) were independent risk factors for progression to AKD in patients with AKI. The ROC showed that increased peak serum creatinine (within 7 days after AKI diagnosis) was an important predictor of AKD in patients with AKI (AUC=0.798, P<0.001). Conclusion Increased peak serum creatinine (within 7 days after AKI diagnosis), proteinuria and increased intact parathyroid hormone are independent risk factors for progression to AKD in patients with AKI, providing new evidences and ideas for clinical preventions and treatments of AKD.

Objective:To investigate the significance of plasma pentraxin 3 (PTX3) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH).Methods:Plasma PTX3 levels were tested by ELISA in 48 newly diagnosed sHLH patients, 18 healthy volunteers and 9 lymphoma controls in the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2019. Clinical parameters were collected, and the correlations with PTX3 levels were analyzed.Results:PTX3 level in newly diagnosed group was significantly higher than that of healthy control group [16.29(1.17-66.00) vs. 0.76(0.01-7.86) μg/L, P<0.01]. Patients with lymphoma-associated HLH(LHLH) had higher plasma level of PTX3 than Fhose with infection-associated HLH (IHLH) [24.29(3.36-66.00) vs. 9.56(1.17-36.50)μg/L, P<0.05]. Plasma PTX3 levels in 48 sHLH patients were positively correlated with serum ferritin ( P<0.05). Receiver operating characteristic (ROC) curve for plasma PTX3 levels of sHLH and healthy controls produced a cutoff value at 3.9 μg/L, with its 86.7% sensitivity and 94.4% specificity. And ROC analysis showed that PTX3 17.5 μg/L was the critical value for diagnosis of LHLH from non-LHLH group, that the sensitivity and specificity were 63.0% and 76.2% respectively. The 1-year overall survival (OS) rate in patients with PTX3≥17.5 μg/L was significantly lower in those with PTX3<17.5 μg/L (18.5% vs. 75.8%, P<0.01). Conclusion:These results indicate the potential of PTX3 as a biomarker for diagnosis and prognosis in patients with sHLH.

Objective:To explore the application of list nursing management combined with different artificial liver treatment modes in patients with liver failure.Methods:Fifty-three patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2020 to July 2021 were selected as the control group, 63 patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2021 to July 2022 were selected as the intervention group. According to the different treatment modes of artificial liver for patients, plasma exchange (PE), double plasma molecular adsorption system (DPMAS) and PE + DPMAS treatment were set up in the two groups. The control group received routine nursing care, while the intervention group received checklist nursing care in addition. The changes of albumin (ALB) and prothrombin time (PT) indexes before and after the different treatment modes were compared, together with the occurrence of complications between the two groups after the intervention.Results:The baseline data between the two groups was balanced, the difference had no statistical significant ( P>0.05). After the therapy, the level of ALB of patients who had accepted DPMAS and PE + DPMAS in the intervention group were 25.3(24.0, 27.9) and 23.2(22.4, 26.3) g/L, which were lower than the 28.2(26.3, 29.7) and 29.4(27.2, 30.0) g/L in the control group, the differences were significant ( Z = 2.47, 3.55, both P<0.05). After the therapy, the level of PT of patients in the intervention group under all three treatment modes were 15.8(14.8, 16.8), 22.7(19.2, 26.2) and 6.0(14.6, 20.0) s, which were lower than the 17.4(15.9, 20.9), 26.3(21.4, 36.4) and 21.2(16.9, 23.4) s in the control group, the differences were significant ( Z = 2.10, 2.07, 2.21, all P<0.05). In the intervention group, there were 6 cases of hypotension, anaphylaxis, bleeding, coagulation and infection under the DPMAS treatment mode, which was significant lower than the 11 cases in the control group ( χ2 = 4.97, P<0.05). There were 4 cases in the intervention group with the PE + DPMAS treatment mode occurred complications in above, which were significant lower than the 11 cases in the control group ( χ2 = 6.87, P<0.01). Conclusions:Artificial liver treatment can improve patients′ liver function and coagulation, and list nursing management may help to improve the effect of artificial liver treatment. It can improve nurses′ awareness of risk prejudgement, reduce various risks in the treatment process, reduce the incidence of adverse reactions, and enhance health care and patient satisfaction.

Objective:To evaluate the clinical value of different shimming methods at 7.0 T MR in two-dimensional (2D) and three-dimensional (3D) T 2WI. Methods:Totally 23 healthy volunteers were prospectively recruited from the First Medical Center of PLA General Hospital from November, 2022 to May, 2023, including 12 volunteers who underwent 2D shimming mode and 14 volunteers who underwent 3D shimming mode. 2D shimming mode included patient-specific (PS) mode, direct signal control (DSC) mode, the standard circularly polarized (CP) mode, and volume-specific (VS) mode. 3D shimming mode included universal pulses (UP) mode and CP mode. The image quality for the subtentorial and supratentorial region was assessed by the subjective image quality score and signal-to-noise ratio. Comparisons of quantitative indices between multiple groups were performed using repeated-measures ANOVA or Friedman′s test; comparisons of quantitative indices between 2 groups were performed using paired-samples t test or Wilcoxon signed-rank test. Results:The image quality of subtentorial region and SNR was significant differences in 2D T 2WI with PS mode, DSC mode, CP mode and VS mode ( F=26.74, P<0.001; F=28.24, P<0.001), and the image quality score and SNR of PS mode, DSC mode, VS mode were better than CP mode ( P<0.05). In 2D T 2WI, there was no significant difference in image quality score and SNR of supratentorial region in PS mode, DSC mode, CP mode ( P>0.05). Besides, in 3D T 2WI, the image quality score for subtentorial and supratentorial region of UP mode were better than those of CP mode ( Z=-2.74, P=0.006; Z=-3.24, P=0.001); SNR of subtentorial region was significantly better in UP mode than those in CP mode ( t=3.49, P=0.004). But there was no significant difference in SNR of supratentorial region between the UP mode and CP mode in 3D T 2WI ( P>0.05). Conclusion:T 2WI with different shimming methods at 7.0 T MR can provide data support for the clinical application, which is helpful for the accurate diagnosis of patients with subtentorial lesions.

Since the Global Polio Eradication Initiative was launched by the World Health Assembly in 1988, significant progress has been made in global polio prevention and control. But the occurrence of vaccine-associated paralytic poliomyelitis cases and vaccine-derived poliovirus related cases have become a major challenge during the post-polio era. While coronavirus disease 2019(COVID-19) has brought serious disease burden and economic burden to all countries in the world, prevention and control of vaccine-preventable infectious diseases such as polio should not be neglected under the background of the global common fight against COVID-19. Taking the type Ⅲ VDPV cycle event in Shanghai as an example, the paper discussed how to do a good job of routine inoculation under the prevention and control of COVID-19 to strictly prevent the outbreak of vaccine-preventable infectious diseases.
