Objective To analyze the disease burden of chronic kidney diseases (CKD) attributed to high body mass index (BMI) in China from 1992 to 2021 and predict the disease burden for the next decade, and to provide evidence for the prevention and treatment of CKD. Methods Using the Global Burden of Disease (GBD) database and the Joinpoint model, the average annual percentage rate change (AAPC) of the mortality rate and disability-adjusted life year (DALY) rate was calculated to describe and analyze the CKD disease burden attributed to high BMI in China from 1992 to 2021. The ARIMA model was employed to predict and analyze the change trend of the CKD disease burden. Results From 1992 to 2021, the mortality rate and DALY rate attributed to high BMI-induced chronic kidney disease showed an upward trend. Compared to 1992, the attributed number of deaths increased by 324.38%, and DALYs increased by 268.56%; the mortality rate increased by 64.00%, and the DALY rate grew by 51.62%. From 1992 to 2021, the mortality rate and DALY rate for males were lower than those for females, but the growth rate for males exceeded that of females. From 1992 to 2021, the mortality rate and DALY rate of chronic kidney disease attributed to high BMI in China increased with age. The average annual change rate of chronic kidney disease attributed to high BMI in China from 1992 to 2021 (mortality rate: 1.40 per 100,000 (95% CI: 1.04–1.76), DALY rate: 1.43 per 100 000 (95% CI: 1.17–1.70)) was higher than thHuaiyin Normal University, Huai'anher social demographic index (SDI) regions. The ARIMA model predicted that the age-standardized mortality rate increased from 2.91 per 100 000 in 2022 to 3.05 per 100 000 in 2026, and the age-standardized DALY rate increased from 69.65 per 100 000 in 2022 to 73.58 per 100 000 in 2026. Conclusion Chronic kidney disease attributed to high BMI in China is on the rise, and it will continue to grow in the future. The focus of CKD prevention and control should be on males and the elderly, while active measures should be taken to reduce the occurrence and progression of chronic kidney disease.

ObjectiveTo investigate the risk factors for pyogenic liver abscess （PLA） comorbid with sepsis by analyzing clinical features， and to construct a predictive model. MethodsA retrospective analysis was performed for 489 patients who were hospitalized and diagnosed with PLA in The Affiliated Hospital of Xuzhou Medical University from January 2019 to December 2023， and according to the presence or absence of sepsis， they were divided into sepsis group with 306 patients and non-sepsis group with 183 patients. Related data were collected， including general information， laboratory markers， and outcome measures. The patients were further divided into a training set of 342 patients and a validation set of 147 patients at a ratio of 7∶3， and the training set was used for screening of variables and construction of a predictive model， while the validation set was used to test the performance of the model. An LASSO regression analysis was used for the screening of variables， and a multivariate Logistic regression analysis was used to construct the predictive model and plot a nomogram. The calibration curve， the receiver operating characteristic （ROC） curve， and the decision curve analysis were used for the validation of the model， and internal validation was performed for assessment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical variables between groups. ResultsThere were significant differences between the sepsis group and the non-sepsis group in pulse rate， mean arterial pressure， duration pf symptoms， comorbidity of liver cirrhosis or malignant tumor， leukocyte count， neutrophil count， lymphocyte count， platelet count （PLT）， activated partial thromboplastin time， fibrinogen， C-reactive protein， aspartate aminotransferase， alanine aminotransferase， albumin， total bilirubin （TBil）， creatinine， potassium， and prognostic nutritional index （PNI） （all P<0.05）. In the training set， the LASSO regression analysis identified four predictive factors of pulse rate， PLT， TBil and PNI， and the multivariate Logistic regression analysis showed that pulse rate （odds ratio ［OR］=1.033， 95% confidence interval ［CI］： 1.006‍ ‍—‍ ‍1.061， P=0.018）， PLT （OR=0.981， 95%CI： 0.975‍ ‍—‍ ‍0.987， P<0.001）， TBil （OR=1.086， 95%CI： 1.053‍ ‍—‍ ‍1.125， P<0.001）， and PNI （OR=0.935， 95%CI： 0.882‍ ‍—‍ ‍0.988， P=0.019） were independent influencing factors for the risk of sepsis in patients with PLA. The model constructed based on these factors showed a good predictive ability， with an area under the ROC curve of 0.948 （95%CI： 0.923‍ ‍—‍ ‍0.973） in the training set and 0.912 （95%CI： 0.848‍ ‍—‍ ‍0.976） in the validation set. The decision curve analysis showed that the model has a good net benefit within the range of 0.3‍ ‍—‍ ‍0.9 for threshold probability. ConclusionThe nomogram prediction model constructed based on pulse rate， PLT， TBil， and PNI has a certain clinical value and can well predict the risk of sepsis in patients with PLA.

Depression (Dep) is one of the most common concomitant symptoms of Parkinson's disease (PD), but there is a lack of detailed pathologic evidence for the occurrence of PD-Dep. Currently, the management of symptoms from both conditions using conventional pharmacological interventions remains a formidable task. In this study, we found impaired activation of extracellular signal-related kinase (ERK), reduced levels of transcription and translation, and decreased expression of brain-derived neurotrophic factor (BDNF) in the medial prefrontal cortex (mPFC) of PD-Dep rats. We demonstrated that the abnormal phosphorylation of α-synuclein (pS129) induced tropomyosin-related kinase receptor type B (TrkB) retention at the neuronal cell membrane, leading to BDNF/TrkB signaling dysfunction. We chose SEW2871 as an ameliorator to upregulate ERK phosphorylation. The results showed that PD-Dep rats exhibited improvement in behavioral manifestations of PD and depression. In addition, a reduction in pS129 was accompanied by a restoration of the function of the BDNF/ERK signaling loop in the mPFC of PD-Dep rats.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Numerous neurodegenerative diseases,such as Alzheimer's disease,Parkinson's disease,and amyotrophic lateral sclerosis,exhibit a common pathophysiological hallmark of aberrant protein aggregation and organelle mislocalization.These pathological manifestations are hypothesized to stem from disruptions in axonal transport within neurons,resulting in the im-paired targeting of pathological proteins for degradation and the misplacement of organelles crucial for normal cellular func-tions.This review aims to illustrate the mechanisms responsible for axonal transport deficits in various prevalent neurodegenera-tive diseases,suggesting that these deficits are typically early pathological occurrences that ultimately result in the deterioration of axonal integrity and degenerative alterations.The review may offer novel insights for future fundamental research endeavors.

Objective:To investigate the clinicopathological characteristics of spiradenocarcinoma, cylindrocarcinoma, and spiradenocylindrocarcinoma, and to understand the correlations between their morphological patterns and clinical behaviors.Methods:Seven cases of spiradenocarcinoma, cylindrocarcinoma, and spiradenocylindrocarcinoma diagnosed at Fudan University Shanghai Cancer Center, Shanghai, China from 2015 to 2021 were collected. The clinicopathological characteristics and follow-up data were retrospectively analyzed. Histopathologic evaluation and immunohistochemical studies were carried out.Results:There were four men and three women in the cohort, with ages ranging from 46 to 75 years (mean, 61 years). The tumors were located on the head and neck (four cases), extremities (two cases), and trunk (one case). Histologically, the residuum of a benign neoplasm was present in all cases. One case presented salivary gland-type basal cell adenocarcinoma-like pattern, low-grade (BCAC-LG). Another case showed salivary gland-type basal cell adenocarcinoma-like pattern, high-grade (BCAC-HG). The remaining five cases were invasive adenocarcinoma, not otherwise specified (IAC-NOS). One of IAC-NOS contained a mucinous adenocarcinoma component. Immunohistochemically, BCAC-LG and BCAC-HG predominantly expressed basal cell markers such as p63 and p40, whereas IAC-NOS primarily exhibited positivity for CK7, a glandular epithelial marker. Follow-up was available for six patients, ranging from 1 to 9 years (mean, 4.5 years). Among the four patients of IAC-NOS with follow-up, three showed recurrences, two had regional lymph node metastases, and one died.Conclusions:The malignant components of spiradenocarcinomas, cylindrocarcinomas, and spiradenocylindrocarcinomas in this cohort contain BCAC-LG, BCAC-HG and IAC-NOS. This study also shows the presence of mucinous adenocarcinoma components in IAC-NOS. The tumors with IAC-NOS have a relatively poorer prognosis than those without.

With the widespread adoption of low-dose computed tomography(LDCT)and advancements in computed tomography image resolution,the detection rate of pulmonary nodules,especially smaller ones,has significantly improved.The risk of developing malignant tumors increases with the pulmonary nodule diameter.Video-assisted thoracoscopic surgery(VATS)stands out as the preferred surgical method.The accurate localization of pulmonary nodules is crucial for the success of VATS and remains a significant challenge for thoracic surgeons.Currently,commonly employed localization methods include CT-guided percutaneous positioning,bronchoscope-guided positioning,intraoperative ultrasound positioning,augmented reality(AR),and 3D print-assisted positioning.This review explores recent research progress,highlights the strengths and weaknesses of various pulmonary nodule localization methods.The aim is to provide valuable insights for clinical applications and guide future developments in this field.

Uncovering the risk factors of pulmonary hypertension and its mechanisms is crucial for the prevention and treatment of the disease.In the current study,we showed that experimental periodontitis,which was established by ligation of molars followed by orally smearing subgingival plaques from patients with periodontitis,exacerbated hypoxia-induced pulmonary hypertension in mice.Mechanistically,periodontitis dysregulated the pulmonary microbiota by promoting ectopic colonization and enrichment of oral bacteria in the lungs,contributing to pulmonary infiltration of interferon gamma positive(IFNγ+)T cells and aggravating the progression of pulmonary hypertension.In addition,we identified Prevotella zoogleoformans as the critical periodontitis-associated bacterium driving the exacerbation of pulmonary hypertension by periodontitis,and the exacerbation was potently ameliorated by both cervical lymph node excision and IFNγ neutralizing antibodies.Our study suggests a proof of concept that the combined prevention and treatment of periodontitis and pulmonary hypertension are necessary.

Objective To explore the influencing factors for Hook-wire precise positioning under CT guidance, determine the best positioning management strategy, and develop Nomogram prediction model. Methods Patients who underwent CT-guided Hook-wire puncture positioning in our hospital from July 2018 to November 2022 were selected. They were randomly divided into a training set and a validation set with a ratio of 7 : 3. Clinical data of the patients were analyzed, and the logistic analysis was used to screen out the risk factors that affected CT-guided Hook-wire precise positioning for the training set. The Nomogram prediction model was constructed according to the risk factors, and the goodness of fit test and clinical decision curve analysis were performed. Results A total of 199 patients with CT-guided Hook-wire puncture were included in this study, including 72 males and 127 females, aged 25-83 years. There were 139 patients in the training set and 60 patients in the validation set. In the training set, 70 patients were accurately located, with an incidence of 50.36%. Logistic regression analysis showed that height [OR=3.46, 95%CI (1.44, 8.35), P=0.006], locating needle perpendicular to the horizontal plane [OR=3.40, 95%CI (1.37, 8.43), P=0.008], locating needle perpendicular to the tangent line of skin surface [OR=6.01, 95%CI (2.38, 15.20), P＜0.001], CT scanning times [OR=3.03, 95%CI (1.25, 7.33), P=0.014], occlusion [OR=10.56, 95%CI (1.98, 56.48), P=0.006] were independent risk factors for CT-guided Hook-wire precise localization. The verification results of the Nomogram prediction model based on these independent risk factors showed that the area under the receiver operating characteristic curve (AUC) was 0.843 [95%CI (0.776, 0.910)], and the predicted value of the correction curve was basically consistent with the measured value. The AUC of the model in the validation set was 0.854 [95%CI (0.759, 0.950)]. The decision curves showed that when the threshold probability was within the range of 8%-85% in the training set and 18%-99% in the validation set, there was a high net benefit value. Conclusion Height, the locating needle perpendicular to the horizontal plane, the locating needle perpendicular to the tangent line of skin surface, number of CT scans, and occlusion are independent risk factors for CT-guided Hook-wire accurate localization. The Nomogram model established based on the above risk factors can accurately assess and quantify the risk of CT-guided Hook-wire accurate localization.

Objective To examine the application effectiveness of dual 8F ultrafine pigtail drainage tubes versus a single 28F large-bore chest tube in single-port thoracoscopic lobectomy/segmentectomy. Methods Clinical data of patients who underwent single-port video-assisted thoracoscopic lobectomy/segmentectomy within our medical group from January 2020 to August 2023 were retrospectively analyzed. They were categorized into two groups based on postoperative drainage methods: a dual 8F ultrafine pigtail tubes group and a single 28F large-bore chest tube group. Comparative analysis was performed on perioperative data for the two groups of patients. Results The dual 8F ultrafine pigtail tubes group comprised of 68 patients, with 41 females and 27 males, and an average age of (54.72±13.34) years, while the single 28F large-bore chest tube group comprised of 80 patients, with 40 females and 40 males, and an average age of (57.60±11.04) years. There were statistical differences between the two groups in terms of postoperative drainage volume on day 1, day 2, and day 3, total postoperative drainage volume, postoperative tube placement time, postoperative pain score at 48 hours, maximum postoperative pain score, postoperative hospital stay, postoperative complications related to drainage tubes, and emergency use of pain-relieving medication after surgery (P＜0.05). Conclusion After single-port thoracoscopic lobectomy/segmentectomy, the application of dual ultrafine 8F pigtail drainage tubes can lead to a reduction in postoperative drainage volume and shorten the duration of postoperative drainage tube placement and hospital stay, thereby decreasing postoperative pain and the frequency of emergency pain-relieving medication. Moreover, it lowers the incidence of drainage tube-related complications. In alignment with current enhanced recovery after surgery principles, this approach is advantageous for postoperative recovery.
