Objective:To explore the differences in early clinical features between Kawasaki disease shock syndrome (KDSS) and septic shock (SS).Methods:A retrospective case-control study was conducted. Clinical data was collected from 64 children who were diagnosed with KDSS or SS and admitted to the Department of Critical Care Medicine of Capital Center for Children′s Health, Capital Medical University from January 2018 to February 2025. Mann-Whitney U test, χ2 test, or Fisher′s exact test were used to compare the differences in clinical features, treatment, and outcomes between children with KDSS and SS. Lasso regression was applied to screen predictive variables, and multivariable logistic regression analysis was performed to identify factors associated with KDSS. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of parameters for KDSS. Results:Among the 64 children (30 males and 34 females), the age was 3.6 (1.2, 6.5) years. There were 51 cases in the SS group and 13 cases in the KDSS group. Compared to children with SS, children with KDSS had a longer pre-shock fever duration, lower lactate levels and serum albumin levels, and higher soluble interleukin-2 receptor (sIL-2R) levels (all P<0.05). Additionally, they exhibited a higher incidence of coronary involvement, pericardial effusion, and ascites, a higher utilization rate of intravenous immunoglobulin, and a lower utilization rate of invasive mechanical ventilation (all P<0.05). There was no significant difference in in-hospital mortality between KDSS and SS ( P=0.574). Multivariate logistic regression analysis identified pre-shock fever duration and sIL-2R as independent factors associated with KDSS ( OR=1.52 and 1.54 per 1 000 U increase, 95% CI 1.12-2.05 and 1.06-2.24, respectively; both P<0.05). ROC curve analysis showed that the areas under the curve for pre-shock fever duration and sIL-2R in identifying KDSS were 0.83 (95% CI 0.73-0.94, P=0.001) and 0.70 (95% CI 0.53-0.87, P=0.042), respectively. The optimal cutoff values were 3.5 d and 3.8×10 6 U/L, with sensitivities of 0.91 and 0.82, and specificities of 0.71 and 0.62, respectively. Conclusions:Children with KDSS have higher incidences of coronary involvement, pericardial effusion, and ascites compared to those with SS. Pre-shock fever duration and sIL-2R may serve as potential early indicators for distinguishing KDSS from SS.

Objective:To explore the differences between clinical-pathological-ultrasound features in hepatocellular carcinoma（HCC）with negative and positive des-gamma-carboxy prothrombin（DCP）.Methods:A retrospective analysis was conducted on 649 patients with pathologically confirmed HCC at Zhongshan Hospital，Fudan University from April 2020 to May 2024. Patients were stratified into DCP-negative（177 cases，<40 mAU/ml）and DCP-positive（472 cases，≥40 mAU/ml）groups. Clinical data，pathological features，and ultrasound findings were collected. Conventional ultrasound and contrast-enhanced ultrasound（CEUS）imaging characteristics were analyzed and compared between the two groups，and the correlation between ultrasound features and pathological characteristics were analyzed.Results:The DCP-negative group exhibited a lower incidence of microvascular invasion（10.17% vs. 34.75%， P<0.001）and smaller median tumor diameter（23 mm vs. 40 mm， P<0.001）. Heterogeneous internal echogenicity was less frequent in DCP-negative tumors［48.59%（86/177） vs. 74.58%（352/472）， P<0.001］. CEUS revealed higher rates of arterial-phase iso-enhancement（6.78% vs. 1.69%）and absence of washout（13.56% vs. 4.45%）in DCP-negative HCC（both P<0.001）. CEUS LI-RADS classification showed fewer LR-5 lesions［50.85%（90/177） vs. 59.53%（281/472）］in DCP-negative group（ P<0.001）. Conclusions:HCC with different DCP states has different clinical-pathological-ultrasound features. DCP-negative HCCs are more likely to show atypical enhancement patterns characteristic of HCC.

The development of Traditional Chinese Medicine(TCM)medical alliances plays a pivotal role in enhancing grassroots TCM service capabilities and meeting public demand for TCM healthcare.However,challenges persist in establishing these alliances,including insufficient Party leadership at primary TCM institutions and deficiencies in clinical services,talent de-velopment,and emergency care capacity.This study examines innovative Party building approaches in public hospitals within the new era context,analyzing practical cases of alliance development.Our findings demonstrate that integrating Party building into the governance structure of medical alliances not only strengthens Party leadership at primary TCM institutions but also significant-ly promotes TCM service development.Systematic analysis of case hospital practices reveals several key insights.Firstly,strengthening top-level design through Party committee leadership is crucial.Secondly,addressing the most pressing public healthcare concerns with genuine commitment forms the foundation.Thirdly,deep integration of Party building with core medical services represents the essential approach.Lastly,policy-responsive innovation based on consolidated achievements serves as the key driver.

Objective:To investigate the predictive value of a clinical imaging model based on multi-slice helical computer tomography (MSCT) examination in predicting prognosis of advanced gastric adenocarcinoma.Methods:The retrospective cohort study was conducted. The clinicopatho-logical data of 88 patients with advanced gastric adenocarcinoma who were admitted to the Ningbo Yinzhou No.2 Hospital from January 2019 to January 2021 were collected. There were 62 males and 26 females, aged (60±15)years. All patients underwent preoperative MSCT examination. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers. Univariate and multivariate analyses were conducted using the Logistic regression model. The receiver opera-ting characteristic curve was used to analyze the predictive efficacy of prognosis, and the area under the curve (AUC), sensitivity, and specificity were calculated. Results:(1) Surgical situations and follow-up. All 88 patients underwent radical gastrectomy for gastric cancer and were diagnosed with advanced gastric adenocarcinoma through postoperative pathological examination. All 88 patients were followed up after surgery for 41(range, 36?48)months, with a 3-year overall survival rate of 69.32%. (2) Analysis of factors affecting the prognosis of advanced gastric adenocarcinoma after radical surgery. Results of multivariate analysis showed that preoperative carcinoembryonic antigen (CEA) and extramural venous invasion (EMVI) were independent factors affecting the prognosis of advanced gastric adenocarcinoma after radical surgery ( odds ratio=1.10, 7.72, 95% confidence interval as 1.01?3.82, 1.42?15.42, P<0.05). (3) Construction and evaluation of predictive model. The AUC of predictive efficacy of prognosis for advanced gastric adenocarcinoma of preoperative CEA and EMVI were 0.90 (95% confidence interval as 0.82?0.97) and 0.80 (95% confidence intervalas 0.71?0.89), respectively, with sensitivity of 85.25% and 78.69% and specificity of 100.00% and 81.48%, respec-tively. A predictive model was constructed by combining preoperative CEA and EMVI based on the results of multivariate analysis, and the AUC of the predictive model was 0.93 (95% confidence interval as 0.87?0.98), with sensitivity and specificity of 86.89% and 96.30%. Conclusions:CEA and EMVI are independent factors affecting the prognosis of advanced gastric adenocarcinoma after radical surgery. The predictive model constructed by combining preoperative CEA and EMVI has good predictive efficacy for patient prognosis.

Objective By employing surgically induced varicocele(VC)in SD rats and an apomorphine(APO)test,we screened rats with erectile dysfunction(ED)after VC and explored method to establish VC and ED models.Methods Sixty rats were randomly divided into Control,Sham,and Model groups with 20 rats in each group.Using the Turner method,we partially ligated the left renal vein to induce left VC three times.APO tests were conducted to screen rats with ED after inducing VC.The numbers of erections,genital grooming,and yawning were observed and recorded.The diameter of bilateral spermatic veins were measured.Both testises and kidneys were weighed.HE staining was used to observe pathological changes of penis and left testis.The success rate of modeling was calculated in the Model group.Results A VC and ED model was successfully established in 15 out of 20 rats in the Model group with a success rate of 75％.After modeling,the diameter of the left spermatic vein in the model group was increased significantly(P＜0.01)and was significantly larger than that before modeling(P＜0.01).The diameter of the right spermatic vein in the Model group was increased(P＜0.05)and higher(P＜0.05)than that before modeling.The weight of the left testis in the Model group was significantly decreased(P＜0.01)compared with that of the right testis.No significant difference in the bilateral kidney weights were observed between or within groups(P＜0.05).In the Model group,the numbers of erections,yawning,and genital grooming decreased significantly(P＜0.01)with the time of modeling.Pathological changes of the left testis and penis were significant in the Model group.Conclusions The Turner method increases the diameter of the spermatic vein in rats,causing testis injury and weight loss,and APO tests can be used to screen rats with ED after VC induction.The combination of the two method is suitable to establish an animal model of VC with an ED status similar to humans.

Objective:To analyze the research hot points and trend of general practice in China.Methods:It was a bibliometric analysis. Research papers presentated on Chinese Society of General Practice from 2014 to 2022 were collected. The distribution and its trend were analysed in terms of titles, submission time, research topics, methods and contents as well as authors′ affilation.Results:A total of 944 research papers were included in the analysis. The results showed a general increasing trend in number of research papers presented on annual conferences from 2014 to 2022 with some fluctuation. The papers covered 28 research dimensions; the highest number of papers was on the development of general practice system, the training and education system for general practitioners, and the construction of information technology (576 papers, 61.0%). The most common topic was on primary health services (230 papers, 24.4%), followed by education and training (225, 23.8%) and chronic disease management (212, 22.5%); while fewer papers were dealing with community-based care (39, 4.1%) and rational medication (7, 0.7%). In terms of the affiliation of the first author, 437 papers (46.3%) were from affiliated hospitals of medical universities/colleges, 223 (23.6%) from community health service institutions, 132 (14.0%) from higher education institutions, 118 (12.5%) from non-affiliated hospitals, and 35 (3.7%) were from administration institutions. In terms of regions, it covered all provinces (municipalities/autonomous regions) (including Hong Kong and Taiwan) with few overseas. Shanghai and Beijing contributed more papers than other regions. In terms of research methodology, most papers used quantitative studies (882, 93.7%), less used qualitative studies (39, 4.1%) or mixed studies (23, 2.4%).Conclusion:The analysis indicates that a wide range of contents are involved in general practice research in China, and more high-quality studies are from medical colleges/universities and their affiliated general hospitals, and most papers use quantitative studies.

Objective:To evaluate the value of Sonazoid contrast enhanced ultrasound (CEUS) in preoperative prediction of proliferating cell nuclear antigen 67 (Ki-67) level of hepatocellular carcinoma (HCC) by establishing predictive model based on radiomics features of Kupffer phase.Methods:From October 2020 to August 2021, patients with histologically confirmed HCC lesion and who underwent Sonazoid CEUS examination 1 week before surgery were prospectively enrolled. The radiomics signatures were extracted from the whole tumor region on gray scale images and Kupffer phase images. Two predictive radiomics models were constructed using radiomic method. The predictive performance of 2 models was compared.Results:A total of 50 patients with histologically confirmed single HCC lesions were prospectively enrolled in this study. Among them, histological results revealed 24 HCC lesions with high level representation of Ki-67 (>20%) and 26 HCC lesions with low level representation of Ki-67 (≤20%). Two radiomics predictive models were established based on gray scale images and Kupffer phase images respectively. While compared with model based on B-mode ultrasound images, model based on Kupffer phase images showed significantly higher area under receiver operating characteristic curve (0.753 vs 0.535, P=0.017), accuracy (0.720 vs 0.580, P=0.023) and sensitivity (0.458 vs 0.250, P=0.043). Calibration plot indicated that Kupffer phase model showed better consistency with the actual Ki-67 level than gray scale model. Conclusions:The radiomics model based on Kupffer phase features of Sonazoid CEUS is a preoperative and noninvasive prediction the presentation level of Ki-67 in HCC lesions.
