Objective To explore the value of model established with radiomics features based on contrast enhanced arterial phase CT and model with radiogenomics for predicting prognosis of ovarian serous cystadenocarcinoma(OSC).Methods Enhanced arterial phase CT images of 110 OSC patients were retrospectively collected from 2 centers and The Cancer Imaging Archive(TCIA)database.The radiomics features were extracted,among those related to prognosis were selected to establish a radiomics Cox regression model.Genes data of 399 OSC patients were obtained from The Cancer Genome Atlas(TCGA)database,and genes related to the radiomics features included in the above radiomics model were identified with high Pearson correlation coefficient,and then enrichment gene analyses were performed.For 57 OSC cases with complete enhanced CT and gene data,the hub genes which had the highest connectivity with radiomics prognosis predicting model were detected using Cox regression and protein-protein interaction(PPI).Furthermore,a radiogenomics prognosis predicting model was established with the hub genes.The efficiencies of these 2 models for predicting prognosis of OSC patients were analyzed.Results Finally,the radiomics model included 5 OSC prognosis-related radiomics features,with C-index of 0.782 and 0.735 in corresponding training and test set,respectively.Meanwhile,the radiogenomics model included 30 prognostic hub genes,with C-index of 0.673 and 0.659 in corresponding training and test set,respectively.The survival rates of patients with better predicted prognosis according to radiomics model and radiogenomics model were both higher compared with the others(both P＜0.05).Totally 1 135 mRNA genes were found being associated with radiomics model,including biological behaviors such as cell adhesion,and signaling pathways such as PI3K-Akt,extracellular matrix receptor interaction pathway and type 1 diabetes pathway.Conclusion The radiomics model was effective for predicting prognosis of OSC patients.Analysis of mRNA bioinformatics in OSC patients might provide biological interpretations for the radiomics model.

Objective:To observe the multi-modal fundus imaging features of subretinal drusenoid deposit (SDD) in age-related macular degeneration (AMD), and observe image features.Methods:A prospective clinical study. From December 2019 to December 2023, 65 patients (104 eyes) with a diagnosis of AMD-SDD by spectral domain optical coherence tomography (SD-OCT) examination in Shandong Eye Hospital were included. All eyes were examined by best corrected visual acuity (BCVA), traditional color fundus photography (CFP), ultra-wide-angle scanning laser fundus imaging (UWF), multicolor scanning laser fundus imaging (MC) and SD-OCT. The standard MC images were obtained by using Spectralis HRA+OCT for MC examination. The multi-mode image characteristics of SDD were analyzed retrospectively. Area under curve (AUC) was used to evaluate the sensitivity and specificity of CFP, MC and UWF in detecting SDD.Results:Among 65 patients with SDD, 29 cases of males (52 eyes) and 36 cases of females (52 eyes) was included. There were 26 patients with unilateral SDD and 39 patients with bilateral SDD. The average age was (71.74±10.97) years. The early, middle and late stages of AMD were 31 (29.8%, 31/104), 24 (23.1%, 24/104), 49 (47.1%, 49/104) eyes, respectively. The SDD detected by CFP, MC and UWF was 76 (73.1%, 76/104), 94 (90.4%, 94/104), 96 (92.3%, 96/104) eyes. CFP showed that the edge of SDD in the macular area was blurred. UWF showed that the dot and the ribbon SDD were light yellow pale discrete deposits and light yellow interlaced network deposits respectively. MC showed the dot SDD had a strong yellow-green circular reflection, while the edge of the ribbon SDD was surrounded by a weak reflection, and the boundary was clear. SD-OCT showed that SDD had strong reflection signal, which was located between the retinal pigment epithelium layer and the photoreceptor cell layer. The dot SDD could break through the ellipsoid zone and caused slight uplift or interruption of the external membrane, showing a cone-like strong reflection signal. While the ribbon SDD showed a continuous "hill-like" protrusion, which hardly broke through ellipsoid zone. The sensitivity and specificity of CFP, MC and UWF for SDD were 73.1%, 90.4%, 92.3% and 61.1%, 94.4% and 83.3%, respectively.Conclusions:MC and UWF show high sensitivity and specificity in diagnosing AMD-SDD, which is superior to CFP. SD-OCT can effectively reveal the location and morphoLogical characteristics of SDD under retina.

Objective:To analyze the effect of dexmedetomidine combined with thoracic paravertebral block (TPVB) on sleep quality, serum interleukin-6 (IL-6) and high mobility group protein (HMGB-1) levels in patients undergoing thoracoscopic pulmonary surgery.Methods:The clinical data of 90 patients who received thoracoscopic pulmonary surgery from January 2020 to January 2021 in Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. Among them, 45 patients were given dexmedetomidine combined with TPVB before operation (experiment group), and 45 patients were given TPVB before operation (control group). The indexes of sleep quality were recorded, including Pittsburgh sleep quality index (PSQI) and total sleep time 24 and 48 h after operation. The visual analogue score (VAS) during quiet and cough 1, 6, 12, 24 and 48 h after operation were recorded. The serum substance P (SP), 5-hydroxytryptamine (5-HT), C-reactive protein (CRP), IL-6 and HMGB-1 before operation and 1 d after operation were detected. The adverse reactions were compared between 2 groups.Results:The PSQI 24 and 48 h after operation in experiment group was significantly lower than that in control group: (11.38±4.61) scores vs. (13.65±2.72) scores and (8.78±3.79) scores vs. (10.95±2.81) scores, the total sleep time was significantly longer than that in control group: (7.71±2.64) h vs. (5.49±2.10) h and (9.75±3.14) h vs. (7.82±2.67) h, and there were statistical differences ( P<0.01). The VAS during quiet and cough 1, 6 and 12 h after operation in experiment group was significantly lower than that in control group, and there was statistical difference ( P<0.01); there was no statistical difference in the VAS during quiet and cough 24 and 48 h after operation between 2 groups ( P>0.05). There were no statistical differences in serum SP, 5-HT, CRP, IL-6 and HMGB-1 before operation between 2 groups ( P>0.05); the SP, 5-HT, CRP, IL-6 and HMGB-1 1 d after operation in experiment group were significantly lower than those in control group: (132.59±10.34) ng/L vs. (141.57±12.26) ng/L, (0.73±0.11) μmol/L vs. (0.95±0.09) μmol/L, (32.46±3.54) mg/L vs. (38.53±4.12) mg/L, (145.67±24.68) ng/L vs. (162.79±23.51) ng/L and (70.35±6.81) ng/L vs. (92.36±7.08) ng/L, and there were statistical differences ( P<0.01). The incidence of adverse reactions in experiment group was significantly lower than that in control group: 20.00% (9/45) vs. 48.89% (22/45), and there was statistical difference ( χ2 = 8.32, P = 0.004). Conclusions:Dexmedetomidine combined with TPVB can effectively improve postoperative sleep quality of patients undergoing thoracoscopic pulmonary surgery, relieve pain, and reduce postoperative serum pain mediators and inflammatory factors, with fewer adverse reactions.

ObjectiveTo investigate the effect of Wudan pill on the polarization of macrophages in the rat model of endometriosis （EMT） with cold congeal and blood stasis syndrome based on p38 mitogen-activated protein kinases （p38 MAPK）. MethodFemale SD rats with regular motility cycles were selected and randomly divided into sham-operated group， model group， Wudan pill high， medium， and low-dose groups （2.4， 1.2， and 0.6 g⋅kg^-1）， Chinese patent medicine group， and western medicine group by the random number table method. The method of ice water bath + autologous endometrial transplantation was used to establish the rat model of EMT with cold congeal and blood stasis， and the rats were executed after 4 weeks of continuous drug administration to collect materials. Expression levels of serum tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-4， and transforming growth factor-β （TGF-β） were determined by enzyme-linked immunosorbent assay （ELISA） to assess inflammation. The real-time quantitative polymerase chain reaction （Real-time PCR） was performed to determine the inducible nitric oxide synthase （iNOS）， TNF-α， arginase 1 （Arg1）， and human mannose receptor （CD206） transcriptional levels to evaluate macrophage polarization. Western blot （WB） and immunofluorescence （IF） assays were used to determine the protein expression levels of iNOS and Arg1 to corroborate macrophage polarization. WB and Real-time PCR were used to determine the protein expression levels of the p38 MAPK pathway. ResultAs compared with sham-operated group， the levels of serum TNF-α， IL-1β， TGF-β， and IL-4 of rats in the model group were significantly higher （P<0.05）. In the model group， the protein levels of iNOS， TNF-α， p-p38 MAPK， and phosphorylated-extracellular signal-regulated kinase （p-ERK） in endothelial tissues were significantly higher， the mRNA levels of iNOS， TNF-α， MAPK， and ERK were significantly higher， and the mRNA and protein expression levels of Arg1 and CD206 were significantly lower （P<0.05， P<0.01）. The number of iNOS positive cells in endothelial tissues was significantly increased， and the number of Arg1 positive cells in endothelial tissues in the model group was significantly decreased （P<0.05， P<0.01）. As compared with the model group， the expression of TNF-α， IL-1β， TGF-β， and IL-4 in each administration group was reduced to different degrees， which was especially significant in the Wudan pill high and medium-dose groups and the western medicine group （P<0.05）. The protein expression levels of iNOS， TNF-α， p-p38 MAPK， and p-ERK in endometrial tissues of rats in the Wudan pill high and medium-dose groups， the Chinese patent medicine group， and the western medicine group were significantly lower， the mRNA expression levels of iNOS， TNF-α， MAPK， and ERK were significantly lower， and the protein expression levels of Arg1 and CD206 were significantly higher （P<0.05， P<0.01）. The number of iNOS positive cells in endometrial tissues of rats was significantly decreased in the Wudan pill high and medium-dose groups， the Chinese patent medicine group， and the western medicine group， whereas the number of Arg1 positive cells was increased （P<0.05， P<0.01）. The low， medium， and high doses of Wudan pill were dose-dependent， and the efficacy of the Wudan pill high-dose group was similar to that of the western medicine group. ConclusionWudan pill reduces the inflammatory response in rat model of EMT with cold congeal and blood stasis syndrome and decreases expression levels of TNF-α， IL-1β， IL-4， and TGF-β， thereby prompting polarization of macrophages from M1 to M2 type. The mechanism is presumedly related to p38 MAPK signaling pathway.

Objective:Aimed to investigate the value of adrenocorticotropic hormone (ACTH) stimulation in adrenal venous blood sampling (AVS).Methods:Patients who diagnosed as primary aldosteronism (PA) and completed successful bilateral cannulation judged by selection index (SI) for routine and(or) ACTH stimulation AVS were enrolled. The lateralization index(LI) was calculated to compare the effect of ACTH stimulation on AVS cannulation success rate and lateralization judgment.Results:A total of 73 patients with PA were enrolled in the study, of whom 28 were confirmed as aldosterone producing adenoma (APA) after unilateral adrenalectomy. Cortisol and aldosterone in peripheral and adrenal veins were significantly increased after ACTH stimulation. The left SI was increased from 6.5(3.0-13.6) to 26.8 (16.9-40.3) ( P<0.01) and the right SI from 20.8(4.8-34.8) to 57.6(35.7-80.9) ( P<0.01) after ACTH stimulation. There was no significant difference on LI before and after ACTH stimulation [7.7(2.3-19.6) vs 5.6(1.9-14.6), P=0.14]. The success rates of left and right adrenal cannulation were increased by 15% and 10% respectively after ACTH stimulation. For 57 patients who were determined in successful cannulation by both routine and ACTH stimulation AVS, 27 patients were determined to have lateralization by both AVS methods, 21 patients were determined to have bilateralization, and the consistency of lateralization by both AVS methods was 84%(48/57). Among the 28 patients who were confirmed to be APA after unilateral adrenalectomy, the correct rate of lateralization by both AVS methods was 89% (25/28). Conclusion:ACTH stimulation is able to improve the success rate of bilateral adrenal vein cannulation, and is helpful to judge AVS results. For patients with successful cannulation, there is no significant difference in lateralization judgment for routine and ACTH stimulation AVS.

To investigate the renal venous and spermatic venous sampling in assisting the diagnosis of reninoma. The case of reninoma was retrospectively reviewed together with the literature review of reninoma diagnosed with renal venous and spermatic venous sampling. A young patient with hypertension and headache was admitted to our hospital. Laboratory test showed high plasma renin concentration (>500 mIU/L), and enhanced computed tomography(CT) in the upper abdomen showed a mass in left inferior renal pole. The concentration of renin in the left spermatic vein was significantly higher than that in renal veins and branches, and peripheral vein, which was considered the left reninoma possibility. The left renal mass was resected surgically and pathologic exam revealed reninoma. The renin level and the blood pressure recoveried normal after operation.The literature reported that the positive rate of renal vein segmental blood collection for locating renin tumor was only 8.3%-64%. The possible reason was that reninoma usually located in the renal cortex, and the tumor blood might be collected by renal capsule vein instead of renal vein. In fact, the renal capsule vein intersects with the lateral division of the spermatic vein, but there have been no reports about the localization of reninoma by spermatic vein sampling. Since renin secreted by reninoma may go into the spermatic vein through renal capsule vein, it should be noted that spermatic venous blood should be collected simultaneously in renal vein sampling when locating reninoma.

Objective:To investigate the prognosis after salvage radiotherapy with or without hormone therapy for prostate cancer.Methods:From May 2014 to December 2020, 248 patients undergoing salvage radiotherapy due to prostate-specific antigen (PSA)persistence or biochemical progression after radical prostatectomy at Sun Yat-sen University Cancer Center (n=157) and West China Hospital, Sichuan University (n=91) were analyzed. Median age was 66 (45-78) years old. Median PSA was 23.50 (0.18-845.00) ng/ml. The number of PSA persistence and biochemical progression were 143 (59%) and 105 (42%). The number of pT 2, pT 3a, pT 3b, pT 4, and unknown T stage was 99, 49, 78, 15 and 7 cases.The number of N 0, N 1 and unknown N stage was 153, 44 and 51 cases. 165 cases had positive surgical margin. Gleason score of 6, 7, 8, >8 score and unknown was in 12, 104, 34, 90 and 8 patients. Early and late salvage radiotherapy was performed in 117 and 131 patients, and 70 patients (28%) were CRPC. Hormone therapy was used combined with radiotherapy in 182 patients (73%). PSA decline after radiotherapy was compared with Chi-squre test. Kaplan-Meier method and log-rank test were used to compare progression free-survival (PFS)after radiotherapy. Univariate and multivariate analyses of PFS were performed using Cox proportional hazards model. Early salvage radiotherapy was defined as PSA≤0.5 ng/ml before radiotherapy, and late salvage radiotherapy was defined as PSA>0.5ng/ml. Results:PSA response (PSA decline ≥50%) rate was 94% (233/248), and 82% (203/248) patients had PSA decline ≥ 90%. Twelve (5%) patients had rising PSA after completing radiotherapy, but only 4 (2%) had real progression. The median PFS was 69 months (95% CI 68-70), and 3-year and 5-year PFS rate were 80% and 67%. PFS of PSA persistence and biochemical progression were similar ( HR =0.71, 95% CI 0.37-1.37, P=0.311). Compared with late salvage radiotherapy, early salvage radiotherapy had better PFS [69 (95% CI 68-70) vs. 59 (95% CI 44-74) months, P<0.001]. Compared with hormone sensitive, castration-resistant was associated with worse PFS (5-year PFS rate 74% vs. 51%, P<0.001). In multivariate analysis, Gleason score>8, castration-resistant and late salvage radiotherapy were unfavorable prognostic factors. Conclusions:In patients receiving salvage radiotherapy with or without hormone therapy for PSA persistence and biochemical progression after radical prostatectomy, high PSA level before radiotherapy and castration resistant is associated with poor prognosis.
