ObjectiveTo evaluate the diagnosis and treatment of postoperative pulmonary embolism(PE). MethodsWe retrospectively analyzed clinical manifestations,diagnosis,treatment and prognosis of 51 postoperative PE. Results36 PE (70.59％ ) developed after orthopaedic surgery or with malignant tumors within 1 week after surgery.Dyspnea or chest distress was the most common symptoms.Sudden death was common in patients with PE.Problems in diagnosis of PE included:poor assessment of deep vein thrombosis(DVT) before operation,and the value of beside echocardiography in the diagnosis of patients with suspected high-risk PE was not fully recognized. Twenty-three PE cases received only anticogulant treatment.Intravenous thrombolysis or percutaneous interventional techniques were undertaken in 3 each cases.Cardiopulmonary resuscitation(CPR) simply after sudden death due to postoperative PE was often unsuccessful.ConclusionsPostoperative PE is a common cause of death,currently available measures are often ineffective.The key lies in prevention especially in those of high-risk PE or suspected non-high-risk PE.

Objective To investigate the clinical efficacy of neoadjuvant chemotherapy combined with radical gastrectomy for advanced gastric cancer.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 73 patients who underwent neoadjuvant chemotherapy combined with radical gastrectomy for advanced gastric cancer at the First Affiliated Hospital of Zhejiang University between June 2004 and December 2009 were collected.Neoadjuvant chemotherapy regimens included XELOX and FOLFOX.Patients received radical gastrectomy within 2 weeks after the completion of the last cycle of neoadjuvant chemotherapy and then continued to undergo postoperative neoadjuvant chemotherapy.Observation indicators:(1) adverse event of neoadjuvant chemotherapy;(2) surgical and postoperative situations;(3) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect survival of patients up to December 2014.Measurement data with skewed distribution were described as M (range).Overall survival time was from the beginning of treatment to death or end of follow-up (patients with loss to follow-up).Progression-free survival time was from the beginning of treatment to tumor progression,recurrence and metastasis or death.The survival curve was drawn by the Kaplan-Meier method.Results (1) Adverse event of neoadjuvant chemotherapy:of 73 patients,38 received XELOX regimens and 35 received FOLFOX regimens,with a median cycle of 3 (range,1-7 cycles).There were 55 adverse events during neoadjuvant chemotherapy,including 47 with grade 1-2 and 8 with grade 3-4.(2) Surgical and postoperative situations:all the 73 patients underwent successful D2 radical gastrectomy for gastric cancer,including 40 receiving total gastrectomy,31 receiving distal gastrectomy,1 receiving total gastrectomy with transverse colon resection and 1 receiving distal gastrectomy with cholecystectomy.Of 73 patients,10 with postoperative complications were improved by conservative treatment,including 3 with pleural effusion,2 with peritoneal effusion,2 with anastomotic bleeding,2 with cholecystitis and 1 with lympha fistula.No patient received reoperations or died within 30 days postoperatively.Pathological TNM staging:22 patients were detected in stage Ⅰ-Ⅱ,45 in stage Ⅲ,4 in stage Ⅳ and 2 in stage T0N1M0.Three patients (in stage T0N0M0) had complete remission.Forty-three patients underwent postoperative chemotherapy.(3) Followup:all the 73 patients were followed up for 8-125 months,with a median time of 51 months.The median survival time,5-year overall survival rate and 5-year disease-free survival rate of 73 patients were 52 months,41.1％ and 34.2％,respectively.Conclusion XELOX and FOLFOX regimens of neoadjuvant chemotherapy combined with radical gastrectomy for advanced gastric cancer are safe and effective.

Objective: To investigate the characteristics of 25(OH)D level in children with ASD and its correlation with clinical features. Methods: A total of 196 children with ASD who received outpatient and inpatient rehabilitation training from January 2017 to January 2019 were included in ASD group, and 178 healthy children who visited the hospital during the same period were included in healthy control group. Differences in 25(OH)D levels and general data between study group and healthy control group were compared. In addition, ASD group was divided into 25(OH)D normal group and abnormal group in accordance with 25(OH)D level (≥30 ng/mL). Differences in general data, total score of CARS scale and factor scores were compared between two groups. Finally, the correlation between serum 25(OH)D level and CARS total score and factor scores of children with ASD was evaluated. Results: 25(OH)D level in ASD group was significantly lower than that in healthy control group (P<0.01). The incidence of sleep disorder, dietary bias, vomiting, constipation and diarrhea in children with ASD was statistically significant compared with that of healthy children (P<0.01); there were statistically significant differences in breastfeeding, sleep disorder, dietary bias and diarrhea between 25(OH)D normal group and abnormal group (χ2=4.97，8.69,6.67,3.98,P<0.05); there were statistically significant differences in 10 aspects including CARS total score, interpersonal relationship, imitation, emotional response, physical use ability, relationship with inanimate objects, adaptation to environmental changes, visual response, auditory response and general impression (P<0.05); there was a significant negative correlation between serum 25(OH)D level and CARS total score in children with ASD (r=-0.32, P<0.01). Conclusion Breastfeeding could reduce the risk of 25(OH)D abnormalities in children with ASD. 25(OH)D reduction would cause sleep disorder, dietary bias and gastrointestinal problems, while dietary bias and gastrointestinal problems would affect 25(OH)D uptake and absorption. 25(OH)D might be related to the occurrence of ASD in children. Serum 25(OH)D level could be used as a reference index for the severity of ASD in children.

Objective To characterize the mRNA expression of CXC chemokine IL-8, CC chemokine monocyte chemothractant protein-1 (MCP-1) and regulated on activation,normal T cell expressed and secreted (RANTES), and a newly defined DC chemokine DC- CK1 as well as the expression of IL-8 receptor, MCP-1 receptor and RANTES receptor in human monocyte derived dendritic cells (MoDCs).The migratory responsiveness of MoDC to IL-8, MCP-1 and RANTES was alsso studied. Methods In vitro generated MoDCs were obtained by differentiating monocytes in the presence of GM-CSF and IL-4 for 5 days. The time course of RNA expression was analyzed by RT-PCR and migratoly ability was assessed by a micromultiwell chemotaxis chamber assay. Results IL-8, MCP-1, RANTES and their corres ponding receptors were consistently expressed in MoDCs. DC-CK-1 expression was detectable efter 48 hours of differentiation. MoDC selectively migrated in response to MCP-1 and RANTES but not to IL-8 though transcripts of IL-8 receptor were present. Conclusion Because the capacity of dendritic cells to initiate immune responses depends on their specialized migratory and tissue homing properties, the expression of chemokines and their receptors along with the migratory responsiveness to chemokines of MoDC in our study suggests a potential role of chemokines in the interaction between dendritic cells and T cells and the induction of immune responses.

Dexmedetomidine (DEX ) is an α₂ adrenalin-receptor agonist with potent sedation, analgesia, anti-anxiety and anti-sympathetic effect. Moreover, DEX exert no inhibition of respiratory function with high safety and has considerable clinical application prospect. Children often experience emergency agitation (EA) and other uncomfortable symptom which is associated with special physical and mental state. Thus, an ideal pediatric anesthetic premedication is getting a lot of attention. DEX is superior to other premedication in sedation with high safety. Compared with others, DEX by nasal spray is an ideal drug delivery method to reduce the side effects and facilitate the implementation of the drug. The relevant research progress of the effective dose, efficacy and safety will be reviewed.

Pain is a common and crucial problem in clinical practice, because it has a profound influence on patients in perioperative period. Butorphanol, among plenty of analgesics, is widely used in clinical trials for its various advantages and better analgesic effects. As a typical agonist-antagonist opioid analgesic agent, butorphanol, however, shows different clinical manifestations with different affinity for opioid receptors 25∶4∶1 (κ∶μ∶δ). Besides, butorphanol provides remarkable analgesic and sedative effect in preemptive analgesia, induction and recovery period in general anesthesia, and postoperative analgesia And it could be as a adjuvant to local anaesthesia either. Compared with other opioid drugs, butorphanol is less likely to have side effect on respiratory depression. In addition, its physical dependence is extremely low.

Objective:To investigate the pahtogengesis and pathology of delayed xenograft rejection (DXR) after pig to rhesus monkey heart xenotransplantation.Methods:Heterotopic xenogeneic heart transplantation in the abdominal cavity was performed using piglet as donors.4 monkeys were used as recipients.Complete complement depletion was achieve in the recipients treated with repetitive doses of a high activity cobra venom factor (Y CVF).The recipients were immunosuppressed with a combination of cyclosporine A,cyclophosphamide and steroids.Sera were analyzed for C3,C4 levels and complement activity and anti pig endotheliocyte xenoantibody.The graft were examined histopathologically and immunohistochemically for C3,C4,C5b 9,IgM,IgG,necrosis factor alpha (TNF alpha),intercellular adhesion molecule 1 (ICAM 1),CD57 (NK cells),CD68 (macrophages),CD4 and CD8.Results:The xenografts survived 8,10,13,13 days respectively and all grafts occoured DXR.Venular thrombosis was outstanding feature within DXR xenografts,complicated with interstitial edma,local hemorrhage and myocardial necrosis,with mild to moderate cellular infiltration.The serum C3 levels and complement activity almost decreased to 0 from the day of transplantation due to Y CVF,the C4 level began to decrease 2 4 days before the cardic xenografts losing their function.The anti pig endotheliocyte xenoantibody also decreased after transplantation,and slightly increased during DXR,all rejected xenografts showed C3,C4,C5b 9,IgG and IgM deposits in different degree.Large numbers of macrophages (50% of total leukocytes) were found infiltrating the entire xenograft,a few natural killer cells (8%～10%),some of CD4+T cells (15%) and CD8+T cells (25%) were detcted also,up regulation of ICAM 1 on the graft endothelial cells and TNF alpha in the interstitial were demonstrated in the rejected heart.Conclusion:Both Humor and cell mediated immunologic reaction may play an important role in pahtogengesis of DXR.

Objective:To analyze the value of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 PET/CT in the detection of myocardial injury in patients treated with anti-tumor therapy. Methods:A retrospective study was conducted on 164 patients who underwent 68Ga-FAPI-04 PET/CT to evaluate the efficacy of anti-tumor therapy in Renji Hospital, School of Medicine, Shanghai Jiao Tong University between August 2021 and March 2024. The patients were divided into 68Ga-FAPI-04-positive group ( n=63, 36 males, 27 females, age (66.7±9.6) years) and 68Ga-FAPI-04-negative group ( n=101, 42 males, 59 females, age (55.2±14.1) years) based on the uptake of left ventricular myocardium (LVM). Moreover, FAPI-04 uptake was analyzed based on different types and locations, and the corresponding SUV max differences were analyzed by Kruskal-Wallis rank sum test. The differences of SUV max between 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were analyzed by Mann-Whitney U test. The clinical factors such as gender, age, body mass index (BMI), previous history of coronary heart disease, left ventricular ejection fraction (LVEF), smoking history, hypertension, diabetes, cancer types and immune checkpoint inhibitors (ICIs) treatment were collected, and their predictive values for LVM 68Ga-FAPI-04 uptake were investigated by the binary logistic regression analysis. Results:Fifty patients of the 68Ga-FAPI-04-positive group (79.4%, 50/63) showed focal uptake of LVM, 7 patients (11.1%, 7/63) showed multifocal myocardial uptake, and 6 patients (9.5%, 6/63) showed diffuse myocardial uptake. A total of 127 uptake lesions were found, and most of them were located in the septum (37.8%, 48/127). The SUV max of LVM in 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were 4.00(3.10, 5.40) and 1.31(1.20, 1.40) respectively ( z=-10.82, P<0.001). Differences of the SUV max among focal uptake group, multifocal myocardial uptake group, and diffuse myocardial uptake group were not significantly different (4.00(3.00, 5.10) vs 7.60(3.60, 9.30) vs 3.95(3.05, 5.05); H=3.81, P=0.149). There is no statistically significant difference either in FAPI uptake among different sites of LVM ( H=1.51, P=0.825). Age, previous history of coronary heart disease, BMI, LVEF and ICIs treatment were independent predictive factors for positive 68Ga-FAPI-04 uptake in the LVM (odds ratio ( OR) values: 0.87-10.43, all P<0.05). Conclusion:68Ga-FAPI-04 PET/CT is a potential new imaging method for the visualization of myocardial injury in patients with anti-tumor therapy.

Objective:Objectives To investigate the predictive value of color Doppler flow imaging (CDFI) for the proteinuria following pyeloplasty for congenital ureteropelvic junction obstruction (UPJO) in children.Methods:We identified a series of 206 children with a mean age of (20.0±28.8) months (1-132 months), consisted of 171 males and 35 females, diagnosed with congenital UPJO accepted pyeloplasty from January 2014 to September 2018, the preoperative mean urinary Albumin/Creatinine Ratio (ACR) was (17.3±160.1) mg/mmol and the mean β2-microglobulin/Creatinine Ratio (β2-MG/Cr) was (135.6±383.8) μg/mmol, ultrasound showed a mean renal pelvis dilatation of (3.1±1.5) cm and a mean cortical thickness of (0.3±0.1) cm, and classified as grade Ⅰ-Ⅴ according to the blood flow distribution in renal by CDFI, these children were divided into three groups of increased, decreased and unchanged blood flow according to the postoperative CDFI within 1 week, the postoperative urinary protein and renal function indexes within 1 week and 2 years were retrospectively analysed among groups.Results:Within 1 week postoperatively, an increased, decreased and unchanged blood flow occurred in 113 (54.9%), 31(15.0%), 62(30.1%) children, respectively. Urinary ACR in above mentioned groups was (112.3±400.7), (16.1±29.3), (32.7±48.4) mg/mmol, β2-MG/Cr was (887.4±6061.0), (50.2±62.7), (51.9±57.8)μg/mmol, there were significant differences among groups ( P<0.01). Contralateral hydronephrosis occurred in 21(18.6%), 4(12.9%), 8(12.9%) children, urinary N-Acetyl-β-D-glucosaminidase (NAG) was (7.5±5.2), (7.0±5.4)、(5.7±4.5) U/L, these indexes showed no significant differences among groups. There was a positive correlation between the increased blood flow level and the decreased renal pelvis dilatation (Spearman’s correlation coefficient 0.2, P<0.01), ACR (Spearman’s correlation coefficient 0.4, P<0.01) and β2-MG/Cr (Spearman’s correlation coefficient 0.3, P<0.01). After a follow up of 2 years, 67 children were diagnosed with proteinuria in this series, 51 cases of them with an increased blood flow, which had significantly higher percentage than children with a decreased (4 cases, 12.9%) or unchanged blood flow (12 cases, 19.3%). Logistic multivariate analysis indicated that early postoperative (within 1 week) increased blood flow ( OR=1.9, 95% CI 1.5-2.6), contralateral hydronephrosis ( OR=2.2, 95% CI 1.1-4.8) and urinary NAG ( OR=1.1, 95% CI 1.0-1.1) were predictive of proteinuria, the increased blood flow was independent predictor of proteinuria (Ⅰ level increased: OR=1.9, 95% CI 1.5-2.6). Conclusions:The CDFI reveals good predictive value for the postoperative proteinuria, an early marked increased blood flow postoperatively indicated risk of proteinuria in the long term.
