Objective: To study the effects of single photon emission computed tomography/computed tomography (SPECT/CT) and magnetic resonance imaging (MRI) in the diagnosis of primary bone tumors. Methods: A total of 104 patients with primary bone tumors in Zibo Central Hospital hospital from January 2016 to January 2018 were enrolled in this study. SPECT/CT and MRI examinations were performed on these patients, and the results of the examinations were compared with the results of surgical pathology. The diagnostic efficacy of the two methods for primary bone tumors were compared. Results: ⑴Results of pathological examination: 70 cases were malignant tumors, and 34 cases were benign tumors; results of SPECT/CT: 72 cases were malignant tumors, and 32 cases were benign tumors; MRI: 76 cases were malignant tumors, and 28 cases were benign tumors; there was no difference between the two methods in the diagnosis of primary bone tumors. ⑵ The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of SPECT/CT were 92.86%, 79.41%, 88.46%, 90.28% and 84.38% respectively, slightly higher than those of MRI (91.43%, 64.71%, 82.69%, 84.21% and 78.57%), but the difference was not statistically significant (P>0.05). ⑶ There was a high consistency between SPECT/CT and MRI in the diagnosis of primary bone tumors (Kappa value=0.613). ⑷ SPECT/CT is more accurate in the diagnosis of osteosarcoma, giant cell tumor, myeloma and fibrous dysplasia, while MRI is more accurate in the diagnosis of osteosarcoma, chordoma, Ewing's sarcoma and schwannoma. Conclusions SPECT/CT fusion imaging and MRI have high sensitivity and accuracy in the diagnosis of primary bone tumors, and the results of the two diagnostic methods have high consistency. SPECT/CT has a high accuracy in the diagnosis of ossification and calcification, while MRI has a high accuracy in the diagnosis of bone tumors in bone soft tissue and nervous system. Therefore, the joint application of the two methods can make up for each other's shortcomings and make the diagnosis of primary bone tumor more accurate.

OBJECTIVE: To analyze relation of ASXL2 gene mutation with the clinical characteristics, prognosis and C-KIT gene mutation in acute myeloid leukemia (AML) patients with AML1-ETO fusion gene. METHODS: The clinical data of 63 primary AML patients with AML1-ETO fusion gene were collected and retrospectively analyzed. The mutation of ASXL2 gene was directly sequenced by PCR. The clinical characteristics, C-KIT mutation rate and prognosis were compared between the patients with ASXL2 gene mutation (group A) and non-mutation (group B). RESULTS: Among 63 patients, 8 (12.70%) cases of ASXL2 mutation gene was detected. Hemoglobin level in peripheral blood of patients in group A was significantly lower than that in group B (P＜0.01). There was no significant difference in sex, ages proportion of bone marrow blasts, lymph node enlargement, peripheral blood leukocytes count and platelets between the two groups (P＞0.05). The infiltration of central nervous system, liver and spleen was not found in both groups. The expression of CD33 in group A was significantly lower than that in group B (P＜0.05), but the results of other immunophenotype analysis were not significantly different between the two groups (P＞0.05). The remission rate and median survival time were not significantly different between two groups (P＞0.05). The detection rate of C-KIT gene mutation were not significantly different between group A and group B (P＞0.05). CONCLUSION Among AML patients with AML1-ETO fusion gene, ASXL2 gene mutation accounts for a certain ratio, and the peripheral blood hemoglobin concentration and CD33 expression in these patients are often low. At the same time, ASXL2 gene mutation may not be closely related with C-KIT gene mutation.

Cerebral venous and sinus Thrombosis (CVST) is a rare ischemic cerebrovascular disease,the lesions of 60% patients are involved in multiple venous sinus,of which the superior sagittal sinus thrombosis is most common.The pathogenesis and pathophysiology of CVST has not yet been fully elucidated,and the establishment of stable and ideal animal models can provide a basis for the study of its development,prognosis and efficacy assessment.This article summarizes the characteristics and advantages of several available CVST models,but each method has its own limitations.Therefore,the establishment of a more ideal animal model will help to fully understand the pathogenesis and pathological process of CVST.

BACKGROUNDSleep deprivation (SD) has been used in treatment of depression disorder, and could effectively improve the patients' depressive symptoms.The aim of the study was to explore the effects of SD on electroencephalographic (EEG) and executive function changes in patients with depression.

METHODSEighteen depression patients (DPs) and 21 healthy controls (HCs) were enrolled in the present study. The whole night polysomnography (PSG) was recorded by Neurofax-1518K (Nihon Kohden, Japan) system before and after 36 hours of SD. The level of subjects' depression state was assessed by Visual Analogue Scale (VAS), and the executive function was assessed by Wisconsin Card Sorting Test (WCST).

RESULTSSignificantly decreased sleep latency (SL; before SD: (31.8 ± 11.1) minutes, after SD: (8.8 ± 5.2) minutes, P < 0.01) and REM sleep latency (RL; before SD: (79.8 ± 13.5) minutes, after SD: (62.9 ± 10.2) minutes, P < 0.01) were found after SD PSG in depression patients. Decreased Stage 1 (S1; before SD: (11.7 ± 2.9)%, after SD: (7.3 ± 1.1)%, P < 0.01) and Stage 2 (S2, before SD: (53.8 ± 15.5)%, after SD: (42.3 ± 14.7)%, P < 0.05) of non-rapid eye movement (NREM) sleep, and increased Stage 3 (S3, before SD: (11.8 ± 5.5)%, after SD: (23.6 ± 5.8)%, P < 0.01) and Stage 4 (S4, before SD: (8.8 ± 3.3)%, after SD: (27.4 ± 4.8)%, P < 0.01) NREM sleep were also found. After SD, the depression level in patients decreased from 6.7 ± 2.1 to 2.9 ± 0.7 (P < 0.01). In WCST, the patients showed significantly decreased Response errors (Re, before SD: 22.3 ± 2.4, after SD: 18.3 ± 2.7, P < 0.01) and Response preservative errors (Rpe, before SD: 11.6 ± 3.6, after SD: 9.3 ± 2.9, P < 0.05). Depression patients' RE (t = 2.17, P < 0.05) and Rpe (t = 2.96, P < 0.01) also decreased significantly compared to healthy controls.

CONCLUSIONSD can improve depression symptom and executive function in depression patients.

In theory of TCM, the root cause of knee osteoarthritis () is the deficiency of liver and kidney, while the symptoms are involved with multiple damages of muscles, tendons and joints. The exogenous evil of wind, coldness, dampness and heat as well as the blood stasis usually block the meridians and collaterals, which cause the knee osteoarthritis. Professorselects acupoints based on syndrome differentiation, and treats both root cause and symptoms. He attaches importance to thepoints, and takes pain as acupoints. He also treats the lower part of body using the upper acupoints, and treats knees through stimulating the low back. The basic acupoints include the affected Dubi (ST 35), Yinlingquan (SP 9), Yanglingquan (GB 34), Liangqiu (ST 34), Xuehai (SP 10),point (extral) andpoint in the knees and waist. Fengchi (GB 20) and Geshu (BL 17) are added for the symptom of wind; Guanyuan (CV 4) is added for the symptom of coldness; Zusanli (ST 36) is added for the symptom of dampness; Quchi (LI 11) is added for the symptom of heat; Fenglong (ST 40) and Sanyinjiao (SP 6) are added for the symptom of phlegm-stasis; Ganshu (BL 18) and Shenshu (BL 23) are added for the deficiency of the liver and kidney. The technical combination of acupuncture, including needle-knife, fire needle, bloodletting, regular acupuncture, TDP, are applied to regulate the patients' deficiency and excess using the nine-six reinforcing and reducing methods, and pay high attention to the mind regulation. Using this method, the efficacy is significant.
