ObjectiveTo explore the character of cognitive potential P300 in major depressive disorder ( MDD ) patients between with and without family history and compare the cognitive function between them.MethodsSixty-seven MDD patients with family history and sixty-seven MDD patients without family history were assigned to research group,sixty-seven healthy volunteers were assigned to control group,and ERP P300 detections were conducted in all subjects.Results①To compare with control group ( ( 189.33 ± 51.13 ) ms) and MDD without family history group( ( 193.55 ± 40.01 )ms),the N2 latency was prolonged more significantly in MDD with family history group ( ( 208.40 ± 33.05 ) ms ) (P < 0.05 ).②Compared with control group ( ( 3.38 ± 5.52 ) μV ),the N2 amplitude was decreased more significantly in MDD without ( ( 2.47 ± 1.87 ) μV ) and with family history ( ( 2.36 ± 2.10) μV ),(P < 0.05 ).ConclusionThere is an obvious cognitive function damaged in the MDD patients with and without family history and the MDD patients with family history are more serious.
2. Progress in augmentation therapy mechanism of obsessive compulsive disorder
Journal of Shanghai Jiaotong University(Medical Science) 2019;39(8):919-922
Administration of selective serotonin reuptake inhibitors (SSRI) is a widely used pharmacotherapeutic approach for obsessive-compulsive disorder (OCD) today. However, nearly half of the OCD patients do not respond to SSRI. It has been shown that some antipsychotic drugs can augment the therapeutic effect of SSRI in the patients with OCD, but the augmentation’s effect is still ineffective for some patients. Therefore, it is of great significance to explore the augmentation’s mechanism for further improvement of the clinical treatment. This article reviews some common used augmentation for OCD and discusses the underlying mechanisms.

BACKGROUND:Recently, scholars al over the world have made numerous studies on three-dimensional visualization model of reconstructing maxil ofacial bone tissue, skin, and muscle in the ordinary PC. However, few studies concerned the three-dimensional visualization model of constructing maxil ofacial bone tissue, skin, muscle and blood vessels. OBJECTIVE:To establish a three-dimensional visualization model of the complete maxil ofacial region using an ordinary PC based on spiral CT, MRI data, and three-dimensional reconstruction software. METHODS:One healthy male adult was chosen as the object in this study. CT and MRI were performed respectively to acquire the DICOM standardized image of the sample. Al CT and MRI images were imported to Mimics to construct three-dimensional visualization models of the bones in the maxil ofacial region, some masseter muscles, trigeminal cistern, internal carotid artery and internal jugular vein. Three-dimensional model of the bones in the maxil ofacial region was chosen as the reference. Models of muscles, blood vessels and trigeminal cistern established by MRI images were imported, and registration in space of three-dimensional model was performed. At last, three-dimensional visualization model of the complete maxil ofacial region was acquired. RESULTS AND CONCLUSION:The integrated three-dimensional models of the bones, muscles, skin, trigeminal cistern and blood vessels in the maxil ofacial region established accurately reflected the complex anatomic structure of maxil ofacial region, provided reliable anatomic data for clinical diagnosis and laid a good foundation for sham operations in the future.

BACKGROUND:In recent years, increasing research emphasizes the puncture position of the foramen ovale in skul , but most of the positin methods require a higher personal experience of surgeons and lack of individualized quantitative parameters. OBJECTIVE:To establish a visualized digital model of the foramen ovale in skul , explore the reasonable puncture path and puncture depth of percutaneous treatment of foramen ovale puncture for trigeminal neuralgia, and develop the individualized treatment of trigeminal neuralgia. METHODS:Head CT images from healthy adult male volunteers were obtained and were input into three-dimensional reconstruction software MIMICS 10.01, the three-dimensional visualized models of the skul and skin were established. Using the models, the puncture path of the foramen ovale was designed and the preliminary model of the puncture locator was plotted. RESULTS AND CONCLUSION:The three-dimensional visualized digital model of the foramen ovale puncture path was established with CT scan images by using MIMICS software, which provides reliable anatomical data for clinical teaching and lays the groundwork for the simulation of puncture surgery. On the three-dimensional models, the“needle points”,“target points”, and“midpoint”were determined, and the triangle consisted of the three points was regarded as“positioning plane”. Using these parameters, the positioning instrument is characterized by simple structure, convenient operation, high positioning precision and short period of exposure to radiation, it simulates the foramen ovale puncture needle depth and needle direction in a precise and individualized manner.

OBJECTIVE:
To validate the value of dual energy CT (DECT) in the differentiation of mediastinal metastatic lymph nodes from non-metastatic lymph nodes in non-small cell lung cancer (NSCLC).
METHODS:
In the study, 57 surgically confirmed NSCLC patients who underwent enhanced DECT scan within 2 weeks before operation were enrolled. Two radiologists analyzed the CT images before operation. All mediastinal lymph nodes with short diameter≥5 mm on axial images were included in this study. The morphological parameters [long-axis diameter (L), short-axis diameter (S) and S/L of lymph nodes] and the DECT parameters [iodine concentration (IC), normalized iodine concentration (NIC), slope of spectral hounsfield unit curve (λHU) and effective atomic number (Zeff) in arterial and venous phase] were measured. The differences of morphological parameters and DECT parameters between metastatic and non-metastatic lymph nodes were compared. The parameters with significant difference were analyzed by the Logistic regression model, then a new predictive variable was established. Receiver operator characteristic (ROC) analyses were performed for S, NIC in venous phase and the new predictive variable.
RESULTS:
In 57 patients, 49 metastatic lymph nodes and 938 non-metastatic lymph nodes were confirmed by surgical pathology. A total of 163 mediastinal lymph nodes (49 metastatic, 114 non-metastatic) with S≥5 mm were detected on axial CT images. The S, L and S/L of metastatic lymph nodes were significantly higher than those of non-metastatic lymph nodes (P < 0.05). The DECT parameters of metastatic lymph nodes were significantly lower than those of non-metastatic lymph nodes (P < 0.05). The best single morphological parameter for differentiation between metastatic and nonmetastatic lymph nodes was S (AUC, 0.752; threshold, 8.5 mm; sensitivity, 67.4%; specificity, 73.7%; accuracy, 71.8%). The best single DECT parameter for differentiation between metastatic and nonmetastatic lymph nodes was NIC in venous phase (AUC, 0.861; threshold, 0.53; sensitivity, 95.9%; specificity, 70.2%; accuracy, 77.9%). Multivariate analysis showed that S and NIC were independent predictors of lymph node metastasis. The AUC of combined S and NIC in the venous phase was 0.895(sensitivity, 79.6%; specificity, 87.7%; accuracy, 85.3%), which were significantly higher than that of S (P < 0.001) and NIC (P=0.037).
CONCLUSIONS
The ability of quantitative DECT parameters to distinguish mediastinal lymph node metastasis in NSCLC patients is better than that of morphological parameters. Combined S and NIC in venous phase can be used to improve preoperative diagnostic accuracy of metastatic lymph nodes.

In order to establish the stable andreliable ISSR-PCR System of Lysimachia christinae, L16 (4(5)) orthogonal design, which based on 7 levels of single factor experiment, were used in this study. The variance analysis was carried out by SPSS 19.0, and 5 main factors affecting the reaction system were optimized in 4 levels. The best annealing temperature was selected by the optimized reaction system. And the stability and reliability of this system was tested by 23 samples from different origins. The results showed that the five factors (DNA template, primer, dNTP, Mg2+ and Taq enzyme) were the most impacts on the amplified results of ISSR-PCR of L. christinae. The order of the influence was: primer > Taq enzyme > DNA template > Mg2+ > dNTP. The optimal system, which was determined by multiple comparison on different levels of each factor, was total volume of 25 microL, including DNA template 60 ng, primer 0.3 micromol x L(-1), dNTP 0.2 mmol x L(-1), Mg2+ 1.8 mmol x L(-1), Taq enzyme 1.25 U. The optimal system was stable and reliable tested by 23 samples from different origins. This study lays the foundation for genetic diversity analysis, fine varieties selection and molecular identification of L. christinae, and provides reference for optimization on ISSR-PCR system of other speciesin future.

Objective To investigate the in-stent restenosis after vertebral artery ostium stenting (VAOS),and to determine the risk factors for in-stent restenosis. Methods Respective analysis of clinical data of 775 cases received VAOS in Xuan Wu Hospital of Capital Medical University from Jan. 2006 to Dec. 2012. Severe stenosis of vertebral artery ostium were diagnosed by DSA,and followed-up by ultrasound. The risk factors were assessed by COX analysis for in-stent restenosis ≥50%. Results This study included 775 patients. Surgical success rate was 99. 87%(n=774),technique success rate was 99. 48%(n=771 ). Two patients had cerebral hemorrhage after operation,one of them was dead. Four patients had cerebral infarction. The mean follow-up period was 12 months. The restenosis rate was 35. 89%(234/652 ). 79. 91% of restenosis occurred within 12 months after operation. COX analysis showed the vessels diameter after stenting was the independent predictors of in-stent restenosis (P<0. 01). The in-stent restenosis rate of drug-eluting stents was lower than metal-bare stents (HR 0. 532,95%CI 0. 397-0. 713,P<0. 01). Conclusion The in-stent restenosis was peculiarly prone to the smaller vessels diameter after VAOS. Drug-eluting stents were superior to metal-bare stents in preventing in-stent restenosis.

OBJECTIVE: To compare the echocardiography parameters during different pregnancy trimesters and to determine the reference range of echocardiography for pregnant women.METHODS: Normal pregnant women were recruited from Renji Hospital,Shanghai Jiao Tong University School of Medicine from February 2017 to December 2017.Women were randomly assigned into 4 groups,cardiac ultrasonography was performed in any one of the three trimesters or 42 days postpartum,and the reference ranges of indicators were determined in each group.Non-pregnant women of childbearing age were recruited as controls.Make a comparison of the measurement values of echocardiography at different trimesters of pregnancy.RESULTS: A total of 733 normal pregnant and non-pregnant women were enrolled,and reference values of echocardiography indexes were determined.The reference range of echocardiograph parameters for pregnant women was established for the first time.Compared with non-pregnant women,there were significant differences in echocardiography parameters among these groups. With the increase of gestational age,the radial lines of left and right atria and ventricles enlarged;the aortic root diameter and pulmonary artery diameter increased,and left and right heart systolic function declined. Most of the above changes reached a peak in the third trimester and did not return to the nonpregnancy level at 42 days postpartum. The diastolic function did not change significantly throughout pregnancy or 42 days postpartum.CONCLUSION: The current normal reference range of echocardiography is not fully applicable to pregnant women,so it is of great importance to establish a normal reference range of echocardiography for pregnant women.
