Brain imaging abnormalities are present in schizophrenia (SZ) and bipolar disorder (BD), demonstrating disease-specific changes, yet they also share similarities in certain brain regions or functional characteristics, with SZ potentially exhibiting more extensive brain damage compared to BD. Structural magnetic resonance imaging (MRI) studies demonstrated widespread gray matter reductions in SZ, particularly in the prefrontal and temporal lobes. In BD, gray matter thickening was observed in the prefrontal lobes during manic episodes, while a reduction in gray matter was noted in the amygdala and hippocampus during depressive episodes. Both SZ and BD exhibited increased ventricular volume and reduced overall brain volume. Functional MRI studies revealed reduced functional connectivity in the prefrontal and temporal lobes in SZ, with decreased global and local efficiency in brain regions such as the hippocampus and cingulate gyrus. BD showed enhanced connectivity in the anterior cingulate gyrus and the default mode network (DMN). Both SZ and BD demonstrated altered functional connectivity in areas such as the striatum, salience network, central executive network and DMN. Diffusion tensor imaging studies showed decreased fractional anisotropy (FA) in the corpus callosum of SZ, with a decrease in FA in the left fronto-occipital fasciculus in BD. Both SZ and BD exhibited reduced FA in the uncinate fasciculus and corpus callosum. Magnetic resonance spectroscopy revealed decreased concentrations of glutathione, N-acetylaspartate (NAA) and inositol in the anterior cingulate gyrus of SZ. In BD, glutathione and inositol concentrations were elevated in the anterior cingulate gyrus, while NAA levels decreased during depressive episodes and increased during remission. Both SZ and BD showed increased levels of glutamate and gamma-aminobutyric acid in the prefrontal cortex. This article provides a review of the current evidence on the differences and similarities in multimodal magnetic resonance brain imaging between SZ and BD, aiming to offer a reference for future exploration of neuroimaging biomarkers and the neurobiological mechanisms of SZ and BD.

Schizophrenia is a chronic disabling disease of unknown etiology. Its neuroimaging abnormalities have been confirmed by a large number of studies. However, when these structural abnormalities occur and how they develop over time are unclear. The relationship between structural abnormalities and antipsychotic treatment needs to be further explored. Longitudinal studies on the brain structure of clinical high risk for psychosis, first-episode schizophrenia and chronic schizophrenia, exploring the influence of drug therapy on them, are helpful to construct the trajectories of brain structure changes in the whole course of schizophrenia and dynamically track the brain structure changes, so as to further explore the pathophysiology of schizophrenia. This article reviews the longitudinal research progress of brain structure changes in patients with schizophrenia.

Objective: To evaluate the mid- and long-term efficacy of Hybrid coronary revascularization (HCR) in the treatment of multi-vessel coronary artery disease for 5 years after operation, and to compare the operative effect with those of off-pump coronary artery bypass grafting (OPCABG) for the same period. Methods: From March 2010 to June 2013, 37 patients underwent selective staging HCR surgery (HCR group) due to multi-vessel coronary artery disease in our hospital. All patients were treated by PCI and MIDCAB subsequently. 148 patients with OPCABG completed by the same group of doctors at the same time were served as control group (OPCABG group), and the follow-up period was up to June 2018. The end point of the study was the incidence of major adverse cardiac or cerebrovascular events (MACCE) events in both groups, including cardiac death, new myocardial infarction, secondary coronary revascularization and cerebrovascular accident. Results: The clinical baseline data of the two groups were basically matched. 37 patients in HCR group were successfully operated on, and each patient was completed with LIMA-LAD bypass, 72 drug-eluting stents were implanted. 504 stents were bridged in 148 patients in OPCABG group, each patient was completed with LIMA-LAD bypass, the other target vessels were performed by sequential anastomosis with great saphenous vein as graft. The average follow-up time was 6.3 years (5.1-8.2 years). In HCR group, 33 patients(89%)completed the follow-up, of which 6 (18%) had MACCE events. In OPCABG group, 130 patients(88%)successfully completed the follow-up, of which 19 (15%) had MACCE events. There was no significant difference in MACCE-free survival rate between the two groups (HCR 81.8% vs. OPCABG 73.8%, P>0.05). Conclusion The mid- and long-term effect of HCR is similar to that of OPCABG in the treatment of multi-vessel coronary artery disease, but it has the advantages of less traumatic, faster recovery and less use of blood products. It can be widely used in patients with selective multi-vessel coronary artery disease.

BACKGROUND: Pulmonary thrombosis embolism (PTE) is one of the most severe complications of perioperative radical mastectomy. Massive PTE is often accompanied by shock and hypotension which is characterized by rapid progression and high mortality. There is no standard for the treatment of these patients, which is thoracic surgery, and it is a critical issue in the thoracic surgeons. This article summarizes and analyzes the treatment of two patients with high-risk PTE at the early stage of postoperative lung cancer in our hospital. In addition, we discusses the diagnosis and treatment strategies of these cases to provide a reference for the thoracic surgeons. METHODS: We presented two patients with high-risk PTE at the early stage after thoracic surgery for radical surgery in our hospital back in 2017. One case was treated with intravenous venous interventional thrombolysis, and the other was treated with thrombolysis alone. The treatment effect of two patients and the complications during the treatment has been recorded to detail and summarized. RESULTS: Both patients were female who aged 66 and 61 years old. The time point of pulmonary embolism was 48 h and 45 h after operation, and the time of interventional thrombolysis was 70 minutes and 50 minutes after onset respectively. After 120 minutes and 100 minutes, the drainage after interventional thrombolysis was 4,690 mL and 520 mL respectively. The hospitalization time after thrombolysis was 21 days and 14 days respectively. There was no obvious complication through a follow-up of 6 months. CONCLUSIONS Early postoperative acute massive pulmonary embolism in lung cancer should be treated with pulmonary interventional thrombolysis as soon as possible. Compared with intravenous thrombolysis, pulmonary interventional thrombolysis shows accuracy, easy controlling of dosage, fast curative effect and low bleeding risk.

Objective To study the optimal radiographic conditions for patients with knee arthroplasty (TKA) and the feasibility of clinical application.Methods According to the different exposure modes,including automatic exposure control (AEC) or manual exposure mode (FIXED),the human body specimen was exposed at a certain kV and different mA or mAs.The entrance surface dose (ESD) and dose exposure index(DEI) were recorded,and the subjective image quality was assessed.The test group with optimum parameters obtained with statistical analysis were compared with control group in radiation dose and subjective evaluation.Results In AEC group,ESD and kV showed a negative correlation (r =-0.973,P ＜ 0.05).At the same mA,DEI was firstly decreased and then increased with kV increasing.The subjective image quality score was (1.96 ± 0.56).DEI and physician ratings showed negative correlation (r =-0.840,P ＜ 0.05).In FIXED group,ESD increased with the increasing mAs (r=0.845,P＜0.05).DEI and kV,mAs indicated a positive correlation(r=0.845,P＜0.05).The subjective image quality scores was(4.33 ±0.79) without correlation with DEI.Compared with the control group,the subjective image quality scores of test group increased,and the radiation dose decreased significantly.Conclusion It is optimal using manual exposure mode with 80 kV/l.25-1 mAs,75 kV/2-1 mAs,70 kV/2.5-1.25 mAs,65 kV/3.2-1.6 mAs and 60 kV/3.2-2 mAs for patients with TKA.

Objective To study the effects of decoy strategy targeted to NF-?B on IL-6 in rat's liver after traumatic inflammatin. Methods Ninty six Wistar rats were randomly divided into 4 groups: control group,traumatic inflammation group, decoy ODN group, and mutant decoy ODN group. Rats were killed on 3 , 6, 12, 24, 48 , and 72 h respectively, for the determination of plasma ALT. Hepatocytes were isolated and nuclear protein was extracted, DNA binding activity of NF-?B was measured by EMSA. Decoy ODN's competition inhibition effect was assayed by EMSA. IL-6 gene expression in liver tissue was assessed by RT-PCR and IL-6 protein level was determined by ELISA. Results After traumatic inflammation, DNA binding activity of NF-?B in the liver increased. IL-6 mRNA and protein level also significantly increased and was in positive correlation with the activity of NF-?B. Decoy ODN effectively inhibited the activity of NF-?B ex vivo. After using decoy ODN, IL-6 mRNA and protein levels of liver tissue significantly decreased, plasma ALT levels were also significantly decreased. Conclusions Decoy strategy targeted to NF-?B could effectively inhibit rat's liver IL-6 release by inhibiting specifically the activity of NF-?B.
