ObjectiveTo observe the effect of Shenshu Fujian decoction on platelet-derived growth factor （PDGF）/naked cuticle homolog 2 （NKD2） /Wnt signaling pathway in rats with chronic renal failure （CRF）. MethodsSixty male SD rats were randomly divided into normal group， model group， Niaoduqing group （5 g·kg^-1）， low-dose Shenshu Fujian decoction group （5.5 g·kg^-1）， medium-dose Shenshu Fujian decoction group （11 g·kg^-1）， and high-dose Shenshu Fujian decoction group （22 g·kg^-1）， with 10 rats in each group. A CRF rat model was established by feeding a 0.5% adenine diet for 21 days. After successful modeling， intragastric administration was given once daily for 28 consecutive days. After treatment， the renal morphology of rats was observed. Serum creatinine （SCr） and blood urea nitrogen （BUN） levels were detected. Hematoxylin-eosin （HE） staining and Masson staining were used to detect renal histopathological changes， and collagen volume fraction （CVF） was calculated. Serum levels of inflammatory markers interleukin （IL）-1β and IL-6 were measured using enzyme-linked immunosorbent assay （ELISA）. The expressions of fibronectin 1 （FN1）， type Ⅰ collagen （ColⅠ）， α-smooth muscle actin （α-SMA）， platelet-derived growth factor receptor-β （PDGFR-β）， NKD2， dishevelled protein 2 （DVL2） and β-catenin in renal tissue were detected by immunohistochemistry and Western blot. ResultsCompared with the normal group， the model group showed significant renal pathological changes， a markedly increased kidney weight/body weight ratio （P<0.01）， significantly elevated CVF （P<0.01）， and notably increased serum levels of SCr， BUN， IL-1β， and IL-6 （P<0.01）. Expression levels of FN1， ColⅠ， α-SMA， PDGFR-β， NKD2， DVL2， and β-catenin in renal tissue were also significantly increased （P<0.01）. Compared with the model group， all treatment groups showed significantly decreased kidney weight/body weight ratios and CVF （P<0.01）， as well as markedly decreased serum SCr， BUN， IL-1β， and IL-6 levels. Protein expression levels of FN1， ColⅠ， α-SMA， PDGFR-β， NKD2， DVL2， and β-catenin in renal tissue were decreased， with more pronounced effects observed in the Niaoduqing， medium-dose， and high-dose Shenshu Fujian decoction groups （P<0.05， P<0.01）. ConclusionShenshu Fujian decoction improves renal function， reduces inflammation， and reverses renal fibrosis in CRF rats， possibly by downregulating the expression of PDGF/NKD2/Wnt signaling pathway-related proteins.

Objective To discuss the application of the"rotating guidewire and correcting the filter recovery hook direction technique"("rotation-correction loop technique"for short),a technique invented by the authors in clinical practice,in the retrieval of complex inferior vena cava filter(IVCF),and to discuss its technical skills and advantages.Methods The clinical data of 417 patients carrying an IVCF,who were admitted to the Department of Vascular Surgery of Second Hospital of Shanxi Medical University of China to retrieve IVCF between January 2022 and December 2022,were retrospectively analyzed.Taking the time spent on the retrieval of IVCF and the intraoperative radiation dose as the evaluation indicators,the advantages and disadvantages of the standard filter retrieval technique,the"rotation-correction loop technique"and the other loop-assisted techniques were compared.Results Both the intraoperative radiation dose and the time spent on the retrieval of IVCF using"rotation-correction loop technique"were remarkably lower than those of other loop-assisted techniques(P＜0.000 1).Conclusion For the retrieval of complex IVCF,especially for the IVCF which is heavily tilted and/or its recovered hook is attached to the vascular wall,the use of"rotation-correction loop technique"can shorten the time spent on the the retrieval of IVCF and reduce the intraoperative radiation dose.This technique carries high safety and practicability,the device is simple and it can be manipulated by single physician,which is conducive to clinical application and promotion.(J Intervent Radiol,2024,33:289-294)

ObjectiveTo investigate the influence of sarcopenia on bone mass loss， the risk factors for bone mass loss in liver cirrhosis， and the correlation between body composition and bone mineral density （BMD） by comparing the clinical features of bone mass loss in patients with liver cirrhosis. MethodsA total of 92 patients who were hospitalized and diagnosed with liver cirrhosis in Department of Gastroenterology， The Second Affiliated Hospital of Kunming Medical University， from April to December of 2022 were enrolled， and based on the results of dual-energy X-ray absorptiometry， they were divided into bone mass loss group （osteopenia/osteoporosis） with 57 patients and normal bone mass group with 35 patients. The two groups were compared in terms of general data， laboratory examination， imaging data， and body composition analysis. The independent samples t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the continuity correction chi-square test was used for comparison of categorical data between two groups； Pearson correlation analysis and Spearman correlation analysis were used to investigate correlation； a binary logistic regression analysis was used to investigate the risk factors for bone mass loss in liver cirrhosis. ResultsCompared with the normal bone mass group， the bone mass loss group had significantly higher age （t=-3.597， P<0.05）， proportion of female patients （χ²=8.393， P<0.05）， N-terminal middle molecular fragment of osteocalcin （N-MID） （Z=-3.068， P<0.05）， β isomer of C-terminal telopeptide of type I collagen （β-CTX） （t=-2.784， P<0.05）， and proportion of patients with sarcopenia （χ²=13.884， P<0.05） and significantly lower calcitonin （CT） （Z=-2.340， P<0.05） and L3 skeletal muscle index （L3-SMI） （t=4.621， P<0.05）. Compared with the normal bone mass group， the bone mass loss group had significantly lower total muscle mass （Z=-2.952， P<0.05）， right upper limb muscle mass （Z=-2.929， P<0.05）， left upper limb muscle mass （Z=-2.680， P<0.05）， right lower limb muscle mass （Z=-3.366， P<0.05）， left lower limb muscle mass （Z=-3.374， P<0.05）， presumed bone mass （t=2.842， P<0.05）， body water mass （Z=-2.779， P<0.05）， basal metabolic rate （BMR） （Z=-3.153， P<0.05）， and BMD of L1— L4 and femoral neck （t=9.789， t=10.280， t=10.832， Z=-7.298， t=8.945， all P<0.05）. Total muscle mass， muscle mass of trunk and limbs， presumed bone mass， BMR， and body water mass in body component analysis were positively correlated with L1 — L4 BMD and femoral neck BMD （all P<0.05）， and fat mass was positively correlated with L1 — L4 BMD （all P<0.05）. Sarcopenia （odds ratio ［OR］=8.737， 95% confidence interval ［CI］： 2.237 — 34.129， P=0.002）， age （OR=1.094， 95%CI： 1.019 — 1.175， P=0.013）， and N-MID （OR=1.095， 95%CI： 1.019 — 1.176， P=0.014） were independent risk factors for bone mass loss in patients with liver cirrhosis. ConclusionOld age， female sex， sarcopenia， elevated N-MID， elevated β-CTX， reduction in CT， low muscle mass， low presumed bone mass， low BMR， and low body water mass are the features of bone mass loss in patients with liver cirrhosis， and sarcopenia， age， and N-MID are independent risk factors for bone mass loss in patients with liver cirrhosis. Detailed assessment of body composition changes can help to identify abnormal BMD in patients with liver cirrhosis.

Patients with decompensated cirrhosis often have a reduction in renal function due to severe hepatic insufficiency which results in reduced inactivation of vasodilators, hemodynamic disorders, immune disorders, and infections, and without timely intervention, patients may gradually develop from early prerenal injury to late renal failure. Patients tend to have a low survival rate and great difficulties in treatment. With the gradual clarification of the classification and diagnostic criteria for kidney injury and the discovery of an increasing number of markers for kidney injury, early diagnosis and localization of kidney injury are of great importance for improving the prognosis of patients. This article analyzes the new advances in the pathogenesis, diagnostic criteria, and treatment of renal injury in cirrhotic patients in recent years, so as to provide help for the clinical diagnosis and treatment of cirrhotic patients with renal injury.

Osteoporosis is a common extrahepatic complication of liver cirrhosis, and it not only increases the economic burden of patients, but also brings adverse effects on their quality of life and prognosis. Recent studies have shown that sarcopenia, adiponectin, leptin, irisin, and inflammatory factors are involved in the development of osteoporosis in patients with liver cirrhosis, and commonly used anti-osteoporosis drugs include calcium supplement, vitamin D, and bisphosphonates. This article reviews the advances in the risk factors, pathogenesis, and treatment of liver cirrhosis with osteoporosis and points out that there are still controversies over the influence of some factors on osteoporosis, and further studies are needed to explore related pathogeneses and safe and effective treatment regimens.

Objective:To investigate the effects of non-invasive positive pressure ventilation (NPPV) on plasma B-type natriuretic peptide (BNP) level and Tei index of right ventricle in preterm infants.Methods:Premature infants of gestational age<34 weeks with respiratory distress syndrome who were admitted in Neonatal Intensive Care Unit of Xuzhou Central Hospital and requiring for NPPV from December 2018 to October 2020, were enrolled in the study. Patients were randomly divided into two groups 46 patients received nasal continuous positive airway pressure ventilation (NCPAP group) and 49 patients received bi-level positive airway pressure ventilation (BiPAP group); 42 preterm infants of gestational age<34 weeks and without NPPV were selected as the control group. The plasma BNP, Tei index of right ventricle, mean airway pressure and oxygen index at 0-12 h and 48-60 h after NPPV were monitored in NCPAP group and BiPAP group. The plasma BNP and Tei index of right ventricle at 0-12 h and 48-60 h after admission were monitored in the control group. SPSS 20.0 statistical software was used for data analysis.Results:(1)The plasma BNP and Tei index of right ventricle at 48-60 h after NPPV were significantly higher than those at 0-12 h after NPPV in NCPAP group and BiPAP group [NCPAP group: (287.5±155.5) vs. (179.9±102.3) ng/L, (0.43±0.08) vs. (0.38±0.06); BiPAP group: (303.1±135.4) vs. (186.5±95.6) ng/L, (0.45±0.08) vs. (0.39±0.06); t=6.00, 3.34, 7.47, 4.48; all P<0.05]. There were no significant differences in the plasma BNP and Tei index of right ventricle at 48-60 h and 0-12 h after admission in the control group [(181.9±86.8) vs. (169.5±78.9) ng/L, (0.34±0.05) vs. (0.36±0.05); t=0.83, -1.59; all P>0.05].(2) There were no significant differences in the plasma BNP and Tei index of right ventricle at 48-60 h after NPPV between NCPAP group-and BiPAP group (all P>0.05), but they were significantly higher than those in control group at 48-60 h after admission(all P<0.05). (3)The mean airway pressure and oxygen index at 48-60 h after NPPV in NCPAP group and BiPAP group showed a decrease trend compared to those at 0-12 h after NPPV, but the differences were not significant [NCPAP group: (6.8±1.2) vs. (7.0±1.3) cmH 2O(1 cmH 2O=0.098 kPa), (5.7±2.1) vs. (6.1±2.3); BiPAP group: (7.0±1.3) vs. (7.2±1.2) cmH 2O, (5.5±2.0) vs. (5.8±2.1); t=-1.05, -0.80, -1.88, -0.67; all P>0.05]; while there were no significant differences between the two groups (all P>0.05). (4)There was a positive correlation between the plasma BNP and mean airway pressure ( r=0.48, P<0.001), but no correlation between Tei index of right ventricle and mean airway pressure ( r=0.17, P=0.119) at 48-60 h after NPPV. Conclusion:The cardiac function indexes such as plasma BNP and Tei index of right ventricle in preterm infants are increased at 48-60 h after NPPV. When mean airway pressure is the same, the effects of NCPAP and BiPAP on plasma BNP and Tei index of right ventricle in preterm infants are similar.

Acute pancreatitis (AP) is a common acute abdominal disease in gastroenterology. Severe patients tend to have high mortality and poor prognosis, and early evaluation of disease conditions and prediction of clinical outcome is of particular importance to improve the prognosis of patients. In recent years, great progress has been made in related markers for predicting the severity stratification and prognosis of patients with AP. This article reviews the value of immune indices, cytokines, genes, biochemical indices, imaging findings, and other related indicators in predicting the severity, mortality, and complications of AP.

Objective To investigate the best scoring systems for predicting the severity and prognosis of hyperlipidemic acute pancreatitis (HLAP) by comparing APACHEII, BISAP, MCTSI, MEWS, POP, SPS, and PANC3 scores. Methods A retrospective analysis was performed for the data of 123 patients with HLAP who were hospitalized and treated in The Second Affiliated Hospital of Kunming Medical University from October 2017 to January 2022. The patients were divided into mild acute pancreatitis (MAP) group with 24 patients, moderate- severe acute pancreatitis (MSAP) group with 56 patients, and severe acute pancreatitis (SAP) group with 43 patients, and the three groups were compared in terms of basic data and scores of the above scoring systems. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups; the chi-square test was used for comparison of categorical data between groups. MedCalc software was used to plot the receiver operating characteristic (ROC) curve, and the area under the ROC curve (AUC) was used to compare the value of these scoring systems in predicting disease severity and local and systemic complications in HLAP patients. Results There were significant differences between the three groups in diabetes mellitus ( χ 2 =6.880, P < 0.05), length of hospital stay ( H =26.494, P < 0.001), local complications ( χ 2 =52.211, P < 0.001), acute kidney injury (AKI) ( χ 2 =38.247, P < 0.001), acute respiratory distress syndrome (ARDS) ( χ 2 =79.201, P < 0.001), and multiple organ dysfunction syndrome (MODS) ( χ 2 =45.032, P < 0.001). As for the scores of the above scoring systems, there were significant differences between the three groups in APACHE Ⅱ, BISAP, MCTSI, MEWS, POP, SPS, and PANC3 ( H =47.525, 42.662, 53.545, 31.664, 49.233, 48.543, and 9.443, all P < 0.05). APACHE Ⅱ score had a significantly higher value than MEWS score in predicting SAP ( Z =2.090, P < 0.05), and the other scores had a similar value, among which POP score had the largest AUC of 0.883. MCTSI score had the highest value in predicting local complications (AUC=0.886), with a sensitivity of 84.7% and a specificity of 74.5% at the cut-off value of 5. APACHE Ⅱ and POP scores had an AUC of 0.911 (95% confidence interval [ CI ]: 0.835-0.986, P < 0.001) and 0.920 (95% CI : 0.866-0.974, P < 0.001), respectively, in predicting AKI; APACHE Ⅱ score had a higher predictive value than MCTSI and MEWS scores, POP score had a higher predictive value than MCTSI, MEWS, and BISAP scores, and SPS score had a higher predictive value than MCTSI score. APACHE Ⅱ score had an AUC of 0.914 (95% CI : 0.854-0.973, P < 0.001) in predicting ARDS and had a higher predictive value than BISAP and MEWS ( Z =2.152 and 3.015, both P < 0.05). APACHE Ⅱ and POP scores had an AUC of 0.969 (95% CI : 0.941-0.996, P < 0.001) and 0.932 (95% CI : 0.880-0.984, P < 0.001), respectively, in predicting MODS, and APACHE Ⅱ score had a higher predictive value than SPS, BISAP, MEWS, and MCTSI. Conclusion POP score has the highest value in predicting SAP, with a comparable predictive ability to all the other scoring systems except MEWS. APACHEII and POP scores have a good value in predicting systemic complications and show a high accuracy in predicting AKI and MODS, and APACHEII score is highly accurate in predicting ARDS.
