Objective:To evaluate the effect of hyperthermia on radiation pneumonitis (RP) in elderly patients with esophageal cancer undergoing intensity-modulated radiotherapy (IMRT).Methods:Clinical data of 177 elderly esophageal cancer patients (aged ≥60 years) receiving IMRT in the First Affiliated Hospital of Soochow University and Yixing Cancer Hospital from August 1, 2017 to February 6, 2023 were retrospectively analyzed. Patients were divided into the hyperthermia and non-hyperthermia groups based on whether they received hyperthermia treatment. Patients in two groups received IMRT with 6 MV X-rays. Patients in the hyperthermia group underwent high-frequency hyperthermia within 1 h before radiation using the external thermotherapy device HG-2000Ⅲ (heating temperature: 41-43 ℃ for 40 min, twice a week). After adjusting for confounding factors between two groups using propensity score matching (PSM), the short-term effective rates between two groups were compared using Chi-square test. Univariate analysis and logistic multivariate analysis were employed to compare the incidence of RP between two groups. Results:After applying PSM, 42 pairs were successfully matched, and the baseline data and radiotherapy parameters showed no statistically significant differences between two groups (all P>0.05). The objective response rate (ORR) in the hyperthermia group was significantly higher than that in the non-hyperthermia group (83.3% vs. 64.3%, P=0.047). Univariate analysis revealed that the incidence of RP and symptomatic RP (≥ grade 2) in the hyperthermia group was significantly lower than that in the non-hyperthermia group (61.9% vs. 85.7%, P=0.013; 21.4% vs. 47.6%, P=0.012). Logistic multivariate analysis indicated that hyperthermia was an independent protective factor for symptomatic RP ( P=0.011). Conclusions:The incidence and severity of RP in elderly esophageal cancer patients receiving IMRT can be reduced by hyperthermia. Hyperthermia, as a clinically beneficial green treatment, improves efficacy and reduces toxicity for patients with esophageal cancer.

Objective:To automatically classify hypertensive heart disease (HHD) and hypertrophic cardiomyopathy (HCM) based on mul-titask learning algorithm using native T1 mapping images.Methods:A total of 203 patients admitted to Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University from January 2017 to December 2021 were enrolled, including 53 patients with HHD, 121 patients with HCM, and 29 patients with normal control (NC). Native T1 mapping images of all enrolled patients were acquired using MRI and processed by a multi-task learning algorithm. The classification performance of each model was validated using ten-fold crossover, confusion matrix, and receiver operator characteristic (ROC) curves. The Resnet 50 model based on the original images was established as a control.Results:The ten-fold crossover validation results showed that the MTL-1 024, MTL-64, and MTL-all models showed better performance in terms of area under the curve (AUC), accuracy, sensitivity, and specificity compared to the Resnet 50 model. In the classification task, the MTL-64 model showed the best performance in terms of AUC (0.942 1), while the MTL-all model reached the highest value in terms of accuracy (0.852 2). In the segmentation task, the MTL-64 model achieved the best results with the Dice coefficient (0.879 7). The confusion matrix plot showed that the MTL model outperforms the Resnet 50 model based on the original image in terms of overall performance. The ROC graphs of all MTL models were significantly higher than the original image input Resnet 50 model.Conclusions:Multi-task learning-based native T1 mapping images are effective for automatic classification of HHD and HCM.

Objective:To design a lung function prediction method that combines transfer learning and multimodal feature fusion, aiming to improve the accuracy of lung function prediction in patients with idiopathic pulmonary fibrosis (IPF).Methods:CT images and clinical text data were reprocessed, and an adaptive module was designed to find the most suitable lung function attenuation function for IPF patients. The feature extraction module was utilized to comprehensively extract features. The feature extraction module comprises three sub-modules, including CT feature extraction, clinical text feature extraction, and lung function feature extraction. A multimodal feature prediction network was used to comprehensively evaluate the attenuation of lung function. The pre-trained model was fine-tuned to improve the predictive performance of the model.Results:Based on the OSIC pulmonary fibrosis progression competition dataset, it is found through the adaptive module that the linear attenuation hypothesis is more in line with the trend of pulmonary function decline in patients. Different modal data prediction experiments show that the model incorporating clinical text features has better predictive ability than the model using only CT images. The model combining CT images, clinical text features, and lung function features have optimal predictive results. The lung function prediction method combining transfer learning and multimodal feature fusion has modified version of the Laplace log likelihood (LLLm) of ?6.706 5, root mean squared error (RMSE) of 184.5, and mean absolute error (MAE) of 146.2, which outperforms other methods in terms of performance. The pre-trained model has higher prediction accuracy compared to the zero base training model.Conclusions:The lung function prediction method designed by combining transfer learning and multimodal feature fusion can effectively predict the lung function status of IPF patients at different weeks, providing important support for patient health management and disease diagnosis.

Objective:To analyze the prognostic factors affecting salvage liver transplantation (SLT).Methods:The clinical data of 97 patients undergoing liver transplantation in the Ningbo Medical Centre Lihuili Hospital from January 2012 to May 2022 were retrospectively analyzed, including 84 males and 13 females, aged (53.6±7.4) years. Among them, 33 patients underwent primary liver transplantation (PLT) and 64 underwent SLT. SLT patients were subdivided into the groups within the Milan criteria (SLT-A, n=35) and beyond the Milan criteria (SLT-B, n=29), according to whether the Milan criteria were met at first hepatectomy. Clinicopathological and prognostic data were subsequently analyzed. Results:The tumor number ( χ2=16.03, P<0.001), microvascular invasion (MVI) ( χ2=10.97, P=0.004), recurrence rate ( χ2=9.31, P=0.010), recurrence-free survival (RFS, F=14.05, P=0.001) and overall survival (OS, F=17.27, P<0.001) were significantly different among the three groups. RFS ( P=0.047) and OS ( P=0.012) in PLT group were better than those in SLT-B group. RFS ( P=0.007) and OS ( P=0.024) in SLT-A group were also better than those in SLT-B group. The multivariate analysis indicated that beyond the Milan criteria at first hepatectomy was an independent risk factor for RFS ( HR=4.378, 95% CI: 1.393-13.756, P=0.011) and OS ( HR=5.391, 95% CI: 1.428-20.352, P=0.013) in patients undergoing SLT, and MVI positive ( HR=4.042, 95% CI: 1.137-14.368, P=0.031) was an independent risk factor for RFS in patients undergoing SLT. Conclusion:Patients beyond the Milan criteria at first hepatectomy and MVI positive showed a poorer prognosis after SLT. Whether the Milan criteria should be the gold standard for SLT as well as for PLT needs further study.

Objective:To observe the efficacy of minocycline combined with barrier cream containing prickly thorn fruit oil and acid slurry extract in the treatment of patients with erythematous telangiectasia or papular pustular rosacea.Methods:From August 2020 to April 2021, 44 patients with rosacea were admitted to the Department of Dermatology, the Ninth People′s Hospital, including 28 males and 16 females, aged 20-56 (37±7) years. They were randomly divided into the observation group (minocycline plus barrier cream) and the control group (minocycline plus vaseline ointment), with 22 patients in each group.Results:After 8 weeks of medication, 21 cases (95.5%) in the observation group were effective, while 16 cases (72.7%) in the control group were effective. The efficacy of the observation group was better than that of the control group, the difference was statistically significant (χ 2=2.06, P=0.039). No significant adverse reactions were observed in both groups. Conclusions:Minocycline combined with barrier cream containing prickly thorn oil and acid slurry extract has a good therapeutic effect on rosacea, which is worthy popularizing.

Objective:To investigate the clinical features and laboratory examination results of complete Kawasaki disease (CKD) versus incomplete Kawasaki disease (IKD). Methods:The clinical data of children with complete Kawasaki disease (CKD group, n = 217) and incomplete Kawasaki disease (IKD group, n = 103) who received treatment in Gansu Provincial Maternity and Child-care Hospital from January 2014 to December 2018 were retrospectively analyzed. Clinical symptom features and laboratory examination indexes were compared between the two groups. Results:The incidence of fever in both groups was 100.0%, but the fever time in the IKD group was (8.97 ± 1.76) days, which was significantly longer than (6.60 ± 1.01) days in the CKD group ( t = 7.68, P < 0.05). The incidences of conjunctival hyperemia, chapped lips, bayberry tongue and finger sclerosis and erythema in the IKD group were 82.5% (84/103), 66.9% (69/103), 21.4% (22/103), and 23.3% (24/103), which were significantly lower than 94.9% (206/217), 76.9% (167/217), 75.1% (163/217), and 81.1% (176/217) in the CKD group ( χ2 = 14.71, 7.09, 82.76, 99.58, all P < 0.05). The incidences of polymorphic rash and perianal peeling in the IKD group were 76.7% (79/103) and 33.9% (35/103), respectively, which were significantly higher than 64.9% (141/217) and 23.5% (51/217) in the CKD group ( χ2 = 4.47, 3.90, both P < 0.05). Digestive and respiratory symptoms were more common in the IKD group than in the CKD group ( P < 0.05). C-reactive protein level in the IKD group was (67.56 ± 23.35) mg/L, which was significantly higher than (53.91 ± 25.06) mg/L in the CKD group ( t = 2.46, P < 0.05), while white blood cell count, platelet count, and B-type brain natriuretic peptide level in the IKD group were significantly lower than those in the CKD group ( t = 2.00, 2.34, 4.69, all P < 0.05). The incidences of coronary artery dilation/small coronary artery aneurysm, and pericardial effusion in the IKD group were greater than those in the CKD group ( χ2 = 6.70, 12.87, both P < 0.05). Conclusion:Children with IKD have a long time of fever. In children without obvious clinical features, attention should be paid to the differential diagnosis of IKD from CKD. IKD should be diagnosed and treated as early as possible to decrease the incidence of coronary artery disease.

Objective:To investigate the correlation between the prognosis of late-onset depression(LOD)in the elderly and lncRNA expression levels and coping styles.Methods:Differential expression of lncRNAs in peripheral blood of LOD 92 patients was detected by a real-time quantitative PCR(qPCR)detection system, and the Hamilton Depression Scale(HAMD)and the Trait Coping Style Questionnaire(TCSQ)were used for psychological assessment.Results:Compared with the control group, the expression levels of TCONS_00019174(7.55 vs.4.36), ENST00000566208(6.48 vs.3.26), ENST00000517573(8.33 vs.5.32)and NONHSAT142707(6.78 vs.3.26)in elderly patients of the LOD group were significantly down-regulated( Z=5.09, 5.87, 4.35, 6.44, P<0.05); Compared with the low-expression subgroup, scores of anxiety/somatization[(3.83±1.40) vs.(6.39±2.35)], diurnal variation[(0.22±0.42) vs.(0.83±0.94)], retardation[(5.74±0.96) vs.(6.48±1.28)], hopelessness[(2.78±0.67) vs.(4.52±1.56)]and HAMD[(20.39±1.75) vs.(26.83±4.88)]in the high-expression subgroup were significantly lower( t=-4.50, -2.84, -2.22, -4.90, -5.96, P<0.05). The ΔCT value of TCONS_00019174 was negatively correlated with the reduction rates of anxiety/somatization, diurnal variation, retardation, sleep disturbance, hopelessness and HAMD( r=-0.40-0.66, P<0.05). The ΔCT value of ENST00000566208 was negatively correlated with the reduction rates of anxiety/somatization, sleep disturbance, hopelessness and HAMD( r=-0.47-0.62, P<0.01). The ΔCT values of ENST00000517573, NONHSAT034045 and NONHSAT142707 were negatively correlated with the reduction rates of retardation, sleep disturbance, hopelessness and HAMD( r=-0.39-0.76, P<0.05). The positive coping style was positively correlated with the reduction rates of HAMD, anxiety/somatization, retardation, sleep disturbance and hopelessness( r=0.38-0.55), while the negative coping style was negatively correlated with the reduction rates of HAMD, anxiety/somatization, sleep disturbance and hopelessness( r=-0.39-0.67, P<0.05). When TCONS_00019174, ENST00000566208, NONHSAT034045, NONHSAT142707, positive coping and negative coping were taken into the regression equation as variables for HAMD reduction, it was found that they were able to explain 32.4% of the variance for the reduction rate of the total HAMD score( t=-8.713, -3.584, -3.864, -2.257, 5.675, -2.357, P<0.05). Conclusions:TCONS_00019174, ENST00000566208, NONHSAT034045, NONHSAT142707, positive coping style and negative coping style are predictors of the prognosis of LOD in the elderly.

Objective:To establish neurodevelopmental mice model of schizophrenia(SZ) with prepulse inhibition(PPI) deficits and investigate the effectiveness of olanzapine on PPI disruption.Methods:On the 9th day of pregnancy of SPF grade C57BL/6 mice, female mice were injected with polyinosinic acid poly (I∶C) (6 mg/kg) through tail vein for immune stimulation. The stress model was constructed by chronic unpredictable mild stress 30-40 d after birth (PND30-40). The offspring mice were divided into pregnancy immune stimulation + adolescent stress group (P + S + group), pregnancy immune stimulation group (P + S- group), adolescent stress group (P-S+ group) and non stimulation group (P-S-group), with 18 mice in each group. The mice in P+ S+ group were divided into OLZ intervention group (OLZ group) and non-OLZ intervention group (non-OLZ group), with 9 mice in each group. The PPI function of mice was detected by acoustic startle reflex test after modeling and OLZ intervention. Adopt StatView Version 5.0 software for data analysis, and multi factors analysis of variance was used to test the main effect, interactive effect and simple effect of each factor.Results:The main effects of maternal Poly(I: C) immune activation and pubertal chronic unpredictable stress were significant( F(1, 330)=47.72, P<0.01), and there was a significant interaction between the two factors( F(1, 330)=14.80, P<0.01), simple effect analysis showed that average percent prepulse inhibition (PPI%) in P+ S+ group((15.42±6.13)%) was significantly decreased compared with groups of P+ S-((27.33±4.58)%), P-S+ ((31.17±3.97)%) and P-S-((47.14±12.28)%)(all P<0.01). There was significant gender difference in Prepulse inhibition(PPI)score( F(1, 396)=61.94, P<0.01), in male and female mice, average startle reactivity of Pulse under Prepulse+ Pulse influence of distinct intensities was significantly different( F(1, 198)=18.68, 18.44, P<0.01), and the maternal Poly(I∶C) immune activation had a significant main effect( F(1, 198)=32.18, 12.58, P<0.01) and interaction with pubertal chronic unpredictable stress( F(1, 198)=34.54, 11.39, P<0.01), simple effect analysis suggested that the average startle reactivity of Prepulse+ Pulse in P+ S+ group(0.47±0.12) was significantly higher than other three groups(P+ S-: 0.36±0.11, P-S+ : (0.25±0.22), P-S-: (0.31±0.19)) in male mice( P<0.01) and in P-S+ group was significantly higher than the other three groups in female mice ( P<0.01). OLZ treatment could efficiently reverse the deficits on PPI by increasing PPI%( F(1, 165)=18.24, P<0.01), OLZ could reduce PPI score in male "dual-hit" model mice( F(1, 102)=21.81, P<0.01)and raise it in female( F(1, 102)=4.88, P<0.05). Conclusion:OLZ can reverse PPI deficits in schizophrenic neurodevelopmental model mice, and in the evaluation of PPI function in the model mice through PPI of acoustic startle reflex, PPI% has better stability and reactivity to OLZ intervention.

Objective:To explore the feasibility of technological modification and innovation of full-left/full-right liver splitting in situ for donors and examine the safety of clinical application for liver transplantation (LT).Methods:From March 2021 to June 2022, clinical and surgical data are retrospectively reviewed for 27 donors undergoing full-left/full-right liver splitting in situ and the corresponding 49 recipients undergoing full-left/full-right LT.According to the split liver technique used in donor liver surgery, they are divided into conventional split group(group A, 13 cases)and innovative split group(group B, 14 cases). The corresponding recipients are divided into two groups of recipient C(25 cases)and recipient D(24 cases). General profiles, intraoperative findings, type of vascular allocation and short-term outcomes in two groups are compared.After full-size split liver transplantation(fSLT), follow-ups continued until the end of September 2022.Results:There are 23 males and 4 females in donors.The causes of mortality for donors are traumatic head injury(12 cases)cerebrovascular accident(13 cases)and anoxia encephalopathy(2 cases). Baseline characteristics of two groups indicate that body weight and body mass index(BMI)are higher in group B and blood sodium level is lower than that in group A( P<0.05). No statistical differences exist for the others.Liver splitting time is significantly shorter in group B than that in group A(175 vs.230 min, P=0.022). No significant inter-group difference exists in type of vascular allocation.Retrohepatic inferior vena cava(IVC)is split in one case in group A and 10 cases in group B( P=0.001). Among 20 cases of right hemiliver requiring a reconstruction of segment Ⅴ/Ⅷ venous outflow, 12 cases in group A and 3 cases in group B are reconstructed with conventional independent bridging method(independent type)while another 5 cases in group B reconstruct with innovated technique by bridging Ⅴ/Ⅷ vein for splitting IVC with iliac vessel and molding all outflows as one for anastomosis(combined typ e). There is significant inter-group difference( P=0.004). No significant differences exist in operative duration, anhepatic phase or blood loss between groups C and B, except for T tube retaining in 7 cases of group A and 14 cases of group D( P=0.032). Twelve cases developed a total of 26 instances of≥Clavien-Dindo grade Ⅲ complications.Of which, 7 cases in group C and 5 cases in group D show no significant difference in postoperative morbidity.However, for serious biliary complications(≥Clavien Dindo grade Ⅲ), there are 6 cases in group C versus none in group D( P=0.016). Two cases died from postoperative complication with a postoperative mortality rate of 4.1%.Postoperative hospital stay is similar in two groups.And accumulates 6/12-month survivals were 95.9% and 87.7% for grafts and 95.9% and 92.4% for recipients respectively. Conclusions:Operative duration of full-left/full-right liver splitting in situ tends to shorten with an accumulation of a certain amount of cases.Technological modification and innovation in IVC splitting and segment Ⅴ/Ⅷ vein reconstruction should be further validated as both feasible and safe by short-term outcomes of the corresponding recipients.

Objective:To explore personality change and its association with lncRNA expression of peripheral blood mononuclear cells in patients with epilepsy.Methods:Fifty-eight epilepsy patients recruited by the convenient sampling were assessed utilizing personality diagnostic questionnaire(PDQ) for personality change screening.The expression levels of lncRNA in peripheral blood of study group and the controls were investigated by qRT-PCR.Descriptive statistical analysis, correlation analysis, regression analysis and ROC analysis were employed for data processing.Results:There were 9 of schizoid (S≥4), 11 of schizotypal(S≥5), 17 of paranoid (S≥4) and 15 of compulsive (S≥4) personality change in epilepsy patients, and 52 patients had different types personality changes(89.66%).Schizoid, schizotypal, paranoid and compulsive personality changes were negatively correlated with expression levels of NONHSAG012869(PR3), NONHSAT006265(PR4), ENST00000581634(PR6) and ENST00000524610(PR8) ( r=-0.46--0.71, P<0.05 or 0.01).PR1, PR3, and PR8 had significant predictive effects on schizoid personality change ( P<0.01), PR4, PR8 had a significant predictive effect on schizotypal personality change ( P<0.01), PR3, PR4 and PR6 had significant predictive effects on paranoid personality change( P<0.05), and PR4, PR5, PR8 had significant predictive effects on compulsive personality change ( P<0.05).The effects of lncRNAs on the personality change variance accounted for 0.36, 0.30, 0.40, 0.20 respectively.ROC curve analysis of the diagnostic value of lncRNA expression level on personality change in the epilepsy group showed that NONHSAG012869 (PR3), NONHSAT006265(PR4), ENST00000581634(PR6) and ENST00000524610(PR8) had certain diagnostic value for personality change.The area under curve(AUC)=0.650-0.682, P<0.05, 95% CI: 0.546-0.784. Conclusion:Schizoid, schizotypal, paranoid, and compulsive personality change are common in epileptic patients, and the expression level of peripheral blood lncRNA has a certain diagnostic value for personality change.
