Objective:To explore the feasibility and adaptability of laparoscopy in the surgical treatment of splenic aneurysm.Methods:The data of 28 patients with splenic aneurysms who underwent laparoscopic surgery in the Department of Hepatobiliary and Pancreatic Surgery of the Third Affiliated Hospital of Soochow University from January 2010 to December 2023 were retrospectively collected and analyzed. Among them, there were 13 males and 15 females, with the age of (57.3±7.7) years. All patients underwent laparoscopic splenic aneurysm resection, and whether to perform splenic artery anastomosis or splenectomy was determined based on the intraoperative situation. Collect the long diameter and location of splenic aneurysms, intraoperative blood loss, operation time, postoperative complications (bleeding, pancreatic fistula, splenic infarction, and splenic vein and portal vein thrombosis), postoperative hospital stay and hospitalization expenses of the patients.Results:All patients successfully underwentlaparoscopic surgery for splenic aneurysms. Aneurysms were located at the origin of the splenic artery in 3 cases (10.7%), in the middle in 8 cases (28.6%), and at the tail in 17 cases (60.7%). The long diameter of the aneurysms was (3.1±1.7) cm. Among the 28 patients, 18 cases (64.3%) underwent splenic aneurysm resection alone, 5 cases (17.9%) underwent splenic aneurysm resection combined with end-to-end anastomosis of the splenic artery, and 5 cases (17.9%) underwent splenic aneurysm resection combined with splenectomy. The operation time of 28 patients was (124.3±55.1) min, the intraoperative blood loss was 100.0 (50.0, 162.5) ml, the postoperative hospital stay was (10.9±3.8) days, and the hospitalization cost was (3.7±1.2) wanyuan. Among the 28 patients, 5 cases (17.9%) developed pancreatic fistula, 1 case (3.6%) had partial splenic infarction, and 1 case (3.6%) had portal vein and splenic vein thrombosis after the operation.Conclusion:Laparoscopic surgery for splenic aneurysm is safe and feasible, with less surgical trauma and quick postoperative recovery.

Objective:To study the feasibility of magnetic resonance imaging(MRI)technique with amide proton transfer(APT)in predicting the prognosis of cerebral stroke.Methods:A total of 71 patients with acute cerebral stroke who admitted to the Nanjing First Hospital,Nanjing Medical University from September 2022 to May 2023 were selected.All of them underwent the test of National Institute of Health Stroke Scale(NIHSS),and received the MRI examination with chemical exchange saturation transfer(CEST).According to the modified Rankin scale(mRS)values of 1-month follow-up,they were divided into favorable recovery group(mRS<2,44 cases)and poor group(mRS≥2,27 cases).The asymmetric magnetization transfer ratio(MTRasym)image(APT)was obtained by analyzing data with special software.And then,the difference(△APTw)of APT values between ischemic zone and contralateral normal tissue was further calculated.The △APTw values of two groups were compared and analyzed,and the Pearson correlation analysis was adopted to analyze the correlation among △APTw,NIHSS and mRS.The receiver operating characteristics(ROC)curve was drawn,and the area under curve(AUC)of ROC curve was calculated.Results:There were significant positive correlations among △APTw,NIHSS and mRS scores(R2=0.659,0.522,P<0.001),and the differences of △APTW,NIHSS and mRS scores between the favorable recovery group and poor group were significant(t=5.73,6.36,13.92,P<0.05),respectively.The AUC value was 0.886,and the sensitivity and specificity of prediction were respectively 77.8%and 95.5%.The positive and negative predictive values were respectively 91.3%and 87.5%.Conclusion:APT imaging technique has feasibility in predicting the prognosis of acute cerebral ischemic stroke.

Objective To develop and validate a prediction model for extended hospitalisation in patients with ischemic stroke.Methods A total of 318 patients with ischemic stroke hospitalised between November 2021 and May 2023 in a Grade ⅢA hospital in Changzhou were selected as study objects with a convenience sampling method.The modelling group consisted 212 patients and the validation group included 106 patients.The patients in the modelling group were divided into a group of extended hospital stay and a group of normal hospital stay.Binary logistic regression analysis was conducted to develop the prediction model,and data from the 106 patients in the validation group were then incorporated into the developed prediction model.The prediction performance and goodness-of-fit of the model were accessed using the area under the curve(AUC)of the receiver operation characteristic(ROC)curve and the Hosmer-Lemeshow test.Results Multivariate logistic analysis showed that comorbid diabetes,number of complications during hospitalisation,a Braden score less than 18,and a white blood cell count greater than 3.5×109/L or more than 9.5×109/L were the risk factors of extended hospitalisation in patients with cerebral ischemic stroke.Based on the factors,a prediction model was developed with following formula:P=1/[1+exp(-Z)].Hosmer-Lemeshow test for the prediction model yielded χ 2=7.430,P=0.191.AUC of the prediction model was 0.818(95％CI:0.754-0.883,P<0.001)with Jordon index of 0.51 and the optimal cut-off value of 0.268,sensitivity of 78.9％and specificity of 72.3％The results of the validation of independent data model showed a sensitivity of 75.0％,specificity of 74.4％,and accuracy of 74.5％.Conclusion Comorbid diabetes,Braden score at admission,white blood cell count and the number of complications during hospitalisation are the significant factors that affect the length of hospital stay in the patients with ischemic stroke.The prediction model for extended hospitalisation of the patients with ischemic stroke exhibits good predictive value and can provide reference in clinical decision-making.

Objective:To observe the effects and safety of dienogest on the volume and symptoms of ovarian endometrioma (OMA).Methods:The clinical data of 75 patients with OMA who underwent treatment with dienogest (2 mg/day) at the First Affiliated Hospital of Nanjing Medical University from July 1st 2020 to March 31st 2024 were retrospectively analysed, mainly comparing the changes in the volume of OMA and the visual analogue scale (VAS) scores of endometriosis-related pain before and after the treatment, as well as observing the changes in the blood biological indicators, liver and kidney function, coagulation function and changes in breast.Results:The median cyst volumes of the OMA patients at 3, 6 and 12 months of dienogest treatment were 13.21 cm 3 (volume reduction rate: 36.00%), 8.33 cm 3 (volume reduction rate: 56.00%) and 4.10 cm 3 (volume reduction rate: 77.62%), respectively, which were all significantly decreased from the pre-treatment period (all P<0.05). The VAS scores of pain of the OMA patients at 3, 6 and 12 months of dienogest treatment all were 0 mm. Blood cancer antigen 125 (CA 125) and cancer antigen 19-9 (CA 19-9) levels decreased progressively during treatment (all P<0.05). There were no statistical differences in the coagulation indexes, liver and kidney function indexes of the patients during dienogest treatment compared with those before treatment (all P>0.05). During the follow-up period, there were a few patients with changes in the growth sites or lesion category of the breast nodules, but there were no occurrence of breast cancer or precancerous lesions. Conclusion:Dienogest is effective in reducing OMA volume and alleviating endometriosis-related pain with few adverse effects.

Immunoglobulin (IgG) glycosylation affects the effector functions of IgG in a myriad of biological processes and has been closely associated with numerous autoimmune diseases, including systemic lupus erythematosus (SLE), thus underlining the pathogenic role of glycosylation aberration in autoimmunity. This study aims to explore the relationship between IgG sialylation patterns and lupus pregnancy. Relative to that in serum samples from the control cohort, IgG sialylation level was aberrantly downregulated in serum samples from the SLE cohort at four stages (from preconception to the third trimester of pregnancy) and was significantly associated with lupus activity and fetal loss during lupus pregnancy. The type I interferon signature of pregnant patients with SLE was negatively correlated with the level of IgG sialylation. The lack of sialylation dampened the ability of IgG to suppress the functions of plasmacytoid dendritic cells (pDCs). RNA-seq analysis further revealed that the expression of genes associated with the spleen tyrosine kinase (SYK) signaling pathway significantly differed between IgG- and deSia-IgG-treated pDCs. This finding was confirmed by the attenuation of the ability to phosphorylate SYK and BLNK in deSia-IgG. Finally, the coculture of pDCs isolated from pregnant patients with SLE with IgG/deSia-IgG demonstrated the sialylation-dependent anti-inflammatory function of IgG. Our findings suggested that IgG influences lupus activity through regulating pDCs function via the modulation of the SYK pathway in a sialic acid-dependent manner.
