Objective To research the visualization of congenital heart disease by three-dimensional echocardiographic(3DE) virtual endoscopy(VE) system. Methods Datasets.from 10 healthy children and 22 patients with congenital heart disease were collected (10 patients with atrial septal defects, 6 patients with ventricular septal defects and 6 patients with tetralogy of Fallot). 3DE heart models were reconstructed by virtual reality computing techniques and visualization in scientific computing techniques. The VE system was programmed under the C++ 6.0 language condition,the visualization toolkit (VTK) platform was employed to carry out the graphics and visualization utilities. The virtual eye can move along the navigation paths in the heart by manual camera movements. Results The VE can provide special information in aspects of intracardiac anatomy, The visible heart models show precisely complex anatomy structure and spatial relationships. 3DE intracardiac endoscopic imaging can thus be visualized and navigated successfully by the VE system. Conclusions 3DE VE is a new system for the visualization of congenital heart disease.

Background and purpose: Ovarian lymphoma (OL) is usually misdiagnosed as ovarian cancer with bulk lymph node invasion (OC-BLN), and vice versa. Therefore, to distinguish these two types of disease, we compared their clinical characteristics in this study. Methods: This study retrospectively reviewed 14 OL and 14 OC-BLN patients from Fudan University Shanghai Cancer Center and Shanghai Eighth People's Hospital. The clinical char-acteristics, image and laboratory examination data were compared. Results: There was no significant difference in age, symptom, fever, weight loss and volume of ascitic fluid between the two groups. Comparing with OC-BLN, OL patients have larger tumor in ovaries [(13.04±5.94) cm vs (7.78±6.38) cm, P=0.033], and higher percentage of solid ovarian tumor (85.71% vs 28.5%, P=0.006). Lactate dehydrogenase(LDH)/CA125 was higher in OL (7.66±8.03) than OC-BLN (0.31±0.27, P=0.009). Using LDH/CA125 to diagnose OL, area under the curve (AUC) was 0.952. When the threshold value was set at 1, the sensitivity and specificity was 91.7% and 100%, respectively. Conclusion: OL and OC-BLN are easily to be misdiagnosed. OL has larger and more solid tumor than OC-BLN. LDH/CA125 can help to distinguish these two diseases and guide clinical decision making.

Objective: We used polysomnography (PSG) monitoring and neuropsychological scales to explore the characteristics of coronavirus disease-2019 (COVID-19) patients diagnosed with post-traumatic stress disorder (PTSD) in Wuhan, two years after the onset of the COVID-19 pandemic. Methods: A total of 42 patients in the Sleep Medicine Center were diagnosed with insomnia between December 2021 and May 2022; they were divided into the PTSD group (patients with PTSD diagnosed with insomnia after COVID-19 infection) and the non-PTSD group (patients with insomnia without PTSD). A healthy control group was simultaneously included. Results: The PTSD group was more significant than the non-PTSD group in partial manifestations of sleep disorders, neuropsychological clinical symptoms, and partial PSG data. Patients with different COVID-19 subtypes showed significant differences in the course of disease, sleep disorders, neuropsychological clinical symptoms, relevant scale scores, and PSG data analysis. Conclusion The emotional anxiety and depression of COVID-19 patients diagnosed with PTSD two years after the COVID-19 pandemic in Wuhan are more significant, and will not be self-alleviated with the passage of time. It is necessary to continue to pay attention to the PTSD symptoms and sleep psychology of COVID-19 infected patients, and take appropriate measures. Patients with severe and critical COVID-19 have more severe sleep and mental disorders, and there is a significant correlation between the duration of the disease and the severity of mental and mental disorders and sleep disorders after recovery.

OBJECTIVE：To study the effects of berberine on mic e macrophage polarization based on TLR 4-MyD88-NF-κB signaling pathway. METHODS ：Using mice RAW 264.7 macrophage as the object ，atorvastatin calcium as positive control ， inflammatory cell model was induced by lipopolysaccharide （LPS）；ELISA method was used to detect the contents of TNF-α，IL-6 and NF-κB in cell culture medium after treated with low，medium and high doses of berberine （5，10，20 μmol/L）for 24 h. The real-time fluorescence quantitative PCR was conducted to determine the mRNA expression of TLR 4 and MyD 88 in cells. Western blotting assay was used to detect the protein expression of TLR 4，MyD88，iNOS and CD 206 in cells. RESULTS ：Compared with blank control group ，the contents of TNF-α，IL-6 and NF-κB in cell culture medium，mRNA expression of TLR 4 and MyD 88， protein expression of TLR 4，MyD88 and iNOS in cells were increased significantly in LPS induction group （P＜0.05）. Compared with LPS induction group ，the contents of TNF-α and IL-6，mRNA and protein expression of TLR 4 and MyD 88 in atorvastatin calcium group ，berberine medium-dose and high-dose groupsas well as the content of NF-κ B and protein expression of iNOS in administration groups were decreased significantly ， while the content of NF-κB in berberine high-dose group was significantly lower than atorvastatin calcium group （P＜0.05）. The protein expressions of CD206 in atorvastatin calcium group and berberine high-dose group were increased significantly ，while the protein expression of CD 206 in berberine high-dose group was significantly higher than atorvastatin calcium group （P＜0.05）. CONCLUSIONS ：Different doses of berberine can intervene in mice macrophage polarization to different extents ，the mechanism of which may be associated with the regulation of TLR4/MyD88/NF-κB signaling pathway.

OBJECTIVE： To systematically evaluate the difference in therapeutic efficacy， safety and cardiac function of Chinese patent medicine injection for promoting blood circulation and removing blood stasis combined with routine treatment after percutaneous coronary intervention （PCI）， and to provide evidence-based reference for clinical drug use. METHODS： Retrieved from Cochrane library， PubMed， Embase， CNKI， Wanfang database and Chinese sci-tech periodicals database， RCTs about different Chinese patent medicine injection for promoting blood circulation and removing blood stasis combined with routine treatment （trial group） versus routine treatment （control group） after PCI were collected. After screening the literature and extracting the data， the quality of the included studies was evaluated by modified Jadad scale. Bayesian network Meta- analysis was performed by using Stata 14.0 software and Markov Chain-Monte Carlo method. RESULTS： A total of 15 RCTs involving 1 364 patients were included， involving Salvia miltiorrhiza injection， Puerarin injection， Yiqi fumai injection， Xuebijing injection， Shenfu injection， Shuxuetong injection， Salvia miltiorrhiza and ligustrazine injection， Rhodiola wallichiana injection， Danhong injection. Results of Meta-analysis showed that in the aspect of improving total response rate of ECG， 8 kinds of intervention measures were involved；compared with control group， 7 kinds of intervention measures could improve the total response rate of ECG of trial group except for Shenfu injection （P＞0.05）； network Meta-analysis ranking showed that S. miltiorrhiza injection＞Puerarin injection＞Shenfu injection＞S. miltiorrhiza and ligustrazine injection＞Shuxuetong injection＞R. wallichiana injection＞ Danhong injection＞routine treatment. In terms of reducing adverse cardiovascular events （MACE） incidence，8 kinds of intervention measures were involved； compared with control group， 7 kinds of intervention measures could reduce the MACE incidence of trial group except for Puerarin injection （P＞0.05）； network Meta-analysis ranking showed that S. miltiorrhiza and ligustrazine injection＞Danhong injection＞Xuebijing injection＞Shuxuetong injection＞S. miltiorrhiza injection＞R. wallichiana injection＞ Puerarin injection＞routine treatment. In terms of improving left ventricular ejection fraction （LVEF） after treatment， 8 kinds of intervention measures were involved； compared with control group， 7 intervention measures could significantly improve LVEF after treatment of trial group except for R. wallichiana injection (P＞0.05）； network Meta-analysis ranking showed that S. miltiorrhiza and ligustrazine injection＞Yiqi fumai injection＞Danhong injection＞Shenfu injection＞S. miltiorrhiza injection＞Shuxuetong injection＞R. wallichiana injection＞routine treatment. CONCLUSIONS： Compared with routine treatment， S. miltiorrhiza injection is the best in improving total response rate of ECG； S. miltiorrhiza and ligustrazine injection is the best in reducing MACE incidence and improving LVEF after treatment.
