Anxiety is a strong behavioral and psychological reaction with fear components, while depression is a mental disorder dominated by high or low mood, both of which are accompanied by cognitive and behavioral changes, and are common comorbidities in patients with heart disease. Cardiac surgery is one of the important factors which trigger specific emotional and physiological reactions of patients. Persistent or initial depression and anxiety after surgery will not only increase surgical complications, short- or long-term mortality and medical costs, but also seriously affect patients' social function and quality of life. With the transformation of bio-psycho-social medical model, it is necessary to evaluate the perioperative psychological state and biological risk of patients undergoing cardiac surgery. This article reviews the characteristics, related mechanisms and therapeutic interventions of anxiety and depression in patients undergoing cardiac surgery.

Objective:To explore the relationship between growth arrest-specific protein 6 (Gas6) and acute myocardial infarction (AMI).Methods:Patients were included from Renmin Hospital of Wuhan University between January to June 2018. A total of 103 patients with angina pectoris aged 60.20±9.35 were included as angina pectoris group. A total of 102 patients with myocardial infarction aged 58.85±9.80 were included as AMI group. A total of 130 healthy individuals aged 63.14±10.40 were included as healthy control. Spearman analysis was performed to investigate the correlations between Gas6 and risk factors of (coronary heart disease, CHD). Logistic regression was performed to investigate the risk factor of myocardial infarction. ROC (receiver operating characteristic) curve was used to analyze the diagnostic performance of Gas6 to AMI.Results:The levels of Gas6 in angina pectoris group [13.77 (10.57-17.03) ng/ ml, t=2.444, P=0.025] and AMI group[16.22 (12.70-20.09) ng/ml, t=4.965, P<0.001] was higher than control group [10.92 (8.90-14.92) ng/ml]. The levels of Gas6 in angina pectoris group was lower than AMI group ( t=3.854, P<0.001). In the sensitivity analysis excluding hypertension and diabetes, the serum Gas6 level in AMI group ( n=37) [15.05 (11.08-16.20) mg/L] was higher than that in control group [10.93 (8.91-14.93)mg/L, t=3.479, P=0.001] and angina group ( n=42) [12.85 (9.10-16.20) mg/L, t=2.639, P=0.019]. CRP (C-reactive protein), WBC (white blood cell count), Glu (fasting glucose) and Cr (creatinine) were positively correlated with Gas6, r=0.194, 0.176, 0.180 and 0.120, P value=0.010, 0.012, 0.010 and 0.002, respectively. Logistic regression showed that Gas6 was a independent factor of myocardial infarction [ OR and 95 %CI were 1.080 (1.012-1.152), P=0.020]. AUC and 95 %CI of ROC curve was 0.648 (0.572-0.723). Conclusion:The levels of Gas6 may be positively associated with myocardial infarction risk.

OBJECTIVETo study lung protection by perfusion with hypothermic protective solution to the pulmonary artery during total correction of tetralogy of Fallot (TOF).

METHODSSixty-four consecutive children with TOF were randomly divided into control group (n = 30) and lung protective group (n = 34). The way of lung protection in the lung protective group was to perfuse with hypothermic protective solution to the pulmonary artery. Patients in the control group were subjected to routine approach. Patients' hemodynamics and lung functions were monitored. Plasma malondialdehyde (MDA), TNF-alpha and IL-6, IL-8 in tracheal suction were measured. Lung biopsy specimens were obtained after operations to study histological changes.

RESULTSThe oxygen index was higher in the lung protect group than in the control group at 6 h, 12 h and 24 h after operation (t = 2.400, P < 0.05; t = 3.898, P < 0.01; t = 3.339, P < 0.01, respectively). The time for ICU and mechanical ventilation was significantly less in the lung protective group than in the control group (t = -2.652, P < 0.05; t = -2.081, P < 0.05). The level of MDA was lower in the lung protective group than in the control group at 0 h and 6 h after operations (t = -4.255, P < 0.01; t = -2.372, P < 0.05 respectively). The level of TNF-alpha was lower in the lung protective group than in the control group at 0 h, 6 h and 24 h after operation (t = 3.112, P < 0.01; t = 3.072, P < 0.01; t = 2.306, P < 0.05, respectively). The levels of IL-6, IL-8 in tracheal suction were lower in the lung protective group (t = -2.419, P < 0.05; t = -2.613, P < 0.01). Tissue examination showed intraalveolar edema, capillary hyperemia, leukocytes accumulated, and mitochondria swelling in the control group, whereas no change in the lung protective group.

CONCLUSIONPerfusion with hypothermic protective solution to the pulmonary artery in CPB could reduce lung injury during the total correction of TOF.

Objective To investigate the MRI features of primary hepatic neuroendocrine tumor (PHNET). Methods Clinical information and MR imaging features of 13 histopathologically confirmed PHNET patients were retrospectively reviewed. All patients underwent routine MRI examination including T2WI and chemical shift imaging, diffusion weighted imaging (DWI) and dynamic contrast-enhanced imaging. All lesions were divided into two groups according to the maximum diameter (≥ 30 mm for large lesion group and<30 mm for small lesion group). The following MRI features of lesions were evaluated:location, size, growth pattern, signal intensity (T1WI, T2WI, DWI, in-and opposed-phase) and dynamic contrast-enhancement pattern. The pathologic features were also analyzed. Results The PHNET can be single lesion(n=7)or multiple lesions(n=6)in which 4 cases showed diffuse pattern.One hundred and six lesions in 13 patients were detected.The median diameter of all lesions was 20 mm(ranging from 3 to 200 mm).Fourteen lesions were found in≥30 mm group and 92 lesions in<30 mm group.(1)In≥30 mm group,all lesions had well-defined margin,heterogeneous hyperintensity on T2WI,heterogeneous hypointensity on T1WI and halo sign on DWI. All lesions showed cystic degeneration, necrosis and pseudo-capsule. Three lesions showed dilation of bile duct around the lesion, and three lesions hemorrhaged and three lesions signal dropped on out-of-phase.On arterial phase,7 lesions showed ring-like enhancement,and the other 7 lesions showed heterogeneous enhancement;then on portal venous phase and delayed phase, 8 lesions showed persistent enhancement and the other 6 lesions showed"wash-out"appearance.Three cases showed lymphadenopathy in the peritoneum and liver hilum. (2) In<30 mm group, 76 lesions showed well-circumscribed edge and the other 16 lesions had ill-defined margin. Eighty two lesions showed relatively homogeneous hyperintensity on T2WI and relatively homogeneous hypointensity on T1WI. One lesion showed heterogeneous hyperintensity on T2WI and heterogeneous hypointensity on T1WI.Nine lesions showed halo and nodular hyperintensity and the other 83 lesions nodular hyperintensity on DWI.Ten lesions demonstrated cystic degeneration and necrosis. Ten lesions showed pseudocapsule. All lesions showed no dilation of bile duct, hemorrhage and signal drop on out-of-phase. On arterial phase, 31 lesions showed ring-like enhancement, 3 lesions showed heterogeneous enhancement and 58 lesions showed homogeneous enhancement;on portal venous phase and delayed phase,62 lesions showed persistent enhancement and 30 lesions showed"wash-out"sign. No lymphadenopathy was found in this group. In the pathologic analysis, hemorrhage and central necrosis were detected in the gross specimens.And in the 13 cases of PHNET,1,3 and 9 cases were classified into G1, G2 and G3 grade, respectively. Conclusions The PHNET can be single or multiple with various sizes. The large lesions often show heterogeneous signal intensity on T2WI and T1WI with cystic degeneration, necrosis, hemorrhage, pseudo-capsule and dilated bile duct, peripheral hyperintensity on DWI, ring-enhancement or heterogeneous slight enhancement in arterial phase, while small lesions often show ring-enhancement or homogeneous obvious enhancement in arterial phase.

Prostate cancer with metastasis to the kidney is rare. Here, we report a case of prostate cancer metastasizing to renal cell carcinoma. A 67-year-old male presented with low back pain for 3 months, aggravated with persistent fever for 2 weeks in June 2018.Histopathological diagnosis of prostate adenocarcinoma was established. Meanwhile, contrasted CT of the abdomen showed a 3.0 cm×2.5 cm×2.5 cm enhanced solid mass on the lower pole of the right kidney. Nephron-sparing surgery was performed for the renal mass. Histopathology revealed a Grade 2 renal clear cell carcinoma with focal prostate carcinoma metastasis to the tumor. Then the patient received abiraterone acetate (AA) therapy. The patient did not encounter tumor recurrence in right kidney 18 months after surgery. However, PSA progression occurred 6 months later after AA therapy, then docetaxel chemotherapy and Sr 89 therapy were performed with limited efficacy. The patient died after 30 months.

Objective:To investigate the clinical characters and prognostic value of PSA flare and bone flare in metastatic castration resistant prostate cancer(mCRPC) patients received Abiterone acetate(AA) therapy.Methods:A retrospective study was conducted for 93 mCRPC patients treated with AA from Jul.2016 to Dec.2020. Mean age was (75.4±8.9)years, median PSA was 58.2 (16.4, 148.6)ng/ml. Patients received at least 6 months of AA treatment. PSA flare was defined as an increase of PSA after AA therapy followed by a decrease. Bone flare was defined as disease progression after 3 months of therapy, typically based on increased lesion intensity or number, and reevaluation 6-9 months later showed improvement in the scan. The clinical characters and prognostic value of the flare phenomenon was evaluated and analyzed respectively.Results:The median follow up time was 16 months(6, 54 months), fourteen patients showed PSA flare at first month after AA treatment, and median time of duration was 2 months(1, 7 months). The serum alkaline phosphatase (ALP) had a similar rising trend along with PSA flare[115.5(98.0, 198.5)U/L vs. 119.0(97.0, 288.8)U/L, P=0.016]. Seven patients showed bone flare and 3 cases co-existed with PSA flare. Multivariate Cox regression analysis indicated bone flare was an independent protective factor for progression free survival(PFS)( HR=0.117, 95% CI 0.015-0.895, P=0.039), PSA flare had no significant influence on PFS ( HR=1.314, 95% CI 0.554-3.121, P=0.536)and overall survival(OS)( HR=1.348, 95% CI 0.393-4.263, P=0.635). Log-rank test showed patients with bone flare had a longer PFS( P=0.016) and OS( P=0.047) compared with patients without bone flare. Conclusions:PSA flare always faded away after 2 months AA therapy and had no influence on PFS and OS. Bone flare maybe an indication for better prognosis.

Takayasu arteritis (TA) is a primary, chronic, non-specific, inflammatory disease of the aorta and its larger branches. The pulmonary artery trunk and its branches could be impacted by TA, which could cause stenosis or occlusion of lesion vessels. TA also affects the normal function of the aortic valve and other heart valves, mainly due to valvular insufficiency. Aortic regurgitation caused by TA is mainly treated by surgical operation. In this review, the examination technique, operation timing, operation method and prognosis of aortic valve involved in TA are discussed systematically.

Objective:To analyze the clinical characteristics and prognostic value of prostate-specific antigen (PSA) dynamic features in patients with metastatic castration resistant prostate cancer (mCRPC) received abiraterone acetate (AA) therapy.Methods:The data of 89 patients with mCRPC who received AA therapy from January 2017 to June 2021 in Shanghai Tongji Hospital were retrospectively reviewed. The age of patients was (75.7 ± 8.3) years old, median PSA before AA was 56.88 (19.31, 143.75) ng/ml. The PSA dynamic features included PSA nadir (PSAN) and PSAN time. PSAN was defined as the lowest value of PSA after treatment, and PSAN time was defined as time to PSAN after AA treatment. PSAN was divided into 3 groups: PSAN1 (<0.1 ng/ml), PSAN2 (0.1- 4.0 ng/ml) and PSAN3 (>4.0 ng/ml) groups. PSA response was defined as a maximum PSA decline rate ≥50%, and no PSA decline after treatment was defined as primary resistance. Cox regressions adjusted to clinical factors were performed to evaluate the influence of PSA dynamic features on patients' radiographic progression-free survival (rPFS) and overall survival (OS). Log-rank test was used to evaluate the survival time of patients in different PSAN groups. Receiver operator characteristic (ROC) curve and area under the curve (AUC) were performed to analyze the predictive value of PSA dynamic features on survival outcomes of patients.Results:The follow-up time was 17 (12, 23) months, and 75 (84.3%) patients showed PSA responses. The median PSAN was 1.82 (0.01, 11.70) ng/ml, median PSAN time was 5.0(3.0, 9.5)months. Multivariate Cox regression indicated that PSAN was an independent risk factor for rPFS ( PSAN2: HR=5.308, P=0.017; PSAN3: HR=13.209, P<0.001), and PSAN time ≥ 5 months( HR=0.309, P<0.001)was an independent protective factor for rPFS. Also, the PSAN3 was an independent risk factor for OS( HR=9.459, P=0.048). Log-rank test indicated that the rPFS of PSAN1 group (median not reached) was significantly longer than PSAN2 [median 13.0(95% CI 8.2-17.8) months, P=0.001] and PSAN3 [8.0 (95% CI 4.1-11.9) months, P<0.001] groups. ROC curve and AUC showed that PSAN had a higher predictive value in rPFS outcomes compared with T stage, metastatic disease volume, and Eastern Cooperative Oncology Group (ECOG) score (0.82 vs. 0.69, 0.68, 0.53, P<0.05). PSAN had a higher predictive value in OS outcomes than metastatic disease volume and ECOG(0.83 vs. 0.63, 0.58, P<0.05). Conclusions:Lower PSAN needs longer PSAN time. PSAN is an independent risk factor for rPFS and OS, and PSAN time is an independent protective factor for rPFS.

Ganoderma lingzhi is widely recognized as a medicinal basidiomycetes. Triterpene acids (TAs) are the key bioactive medicinal components of G. lingzhi. Our previous studies have shown that phospholipid acid (PA) produced by phospholipase D (PLD) plays a regulatory role in TA synthesis. In order to further elucidate the molecular mechanism how PA regulates TA synthesis in G. lingzhi, PA beads enrichment combined with LC-MS/MS technology was used to identify PA interacting proteins in G. lingzhi. A total of 19 PA interacting proteins were identified, including cytochrome P450 monooxygenase (GL22084), specific protein kinase MAPK (GL23765), catalase and cell surface hydrophobicity-associated protein. GST tagged GL22084 and GL23765 proteins were obtained through gene cloning, heterologous expression, and purification. The interactions between GL22084/GL23765 and PA were verified by GST pull down assay. The identification of PA interacting proteins provides a basis for further understanding the molecular mechanism how PLD-mediated PA signaling molecules regulates the TA synthesis in G. lingzhi. Moreover, the PA interacting proteins identified in this study can also provide clues for the research of PLD/PA signaling pathway in other species.
