Bilateral basal ganglia hemorrhage due to tentorial dural arteriovenous fistula: a case report and systematic literature review / 中华神经科杂志

Objective:To investigate the clinical characteristics of cerebral hemorrhage caused by tentorial dural arteriovenous fistula (TDAVF).Methods:An unusual TDAVF case admitted to the Department of Neurology, Qilu Hospital, Shandong University in March 2020, complicated with hypertension with successive bilateral basal ganglia hemorrhage in short term was reported. The characteristics of cerebral hemorrhage caused by TDAVF reported in the literature were summarized and analyzed.Results:Digital subtraction angiography (DSA) revealed that there was arteriovenous fistula in the tentorial foramen area of this patient (male, 33 years old), and the TDAVF was fed by the right meningohypophyseal trunk, bilateral middle meningeal artery and posterior cerebral artery. A shunted pouch was present in the tentorial foramen area, and retrograde reflux drainage was seen in the deep venous system, from the meningeal vein to superior sagittal sinus or sigmoid sinus. Transarterial embolization was performed and subsequently DSA showed obliteration of the fistula. This patient experienced no clinical decline or rehemorrhage during the 12 months follow-up period. Forty-one cases of TDAVF with hemorrhage of cerebral parenchyma which were reported before March 30, 2021 with detailed clinical and imaging data were summarized. The average age of onset of this group of patients was 57.2 years, and the ratio of male to female was about 3∶1. The hemorrhage was located in superior of the tentorium in 17 cases (41%), while in inferior of the tentorium in 24 cases (59%). Supratentorial intracerebral hemorrhage mainly occurred in occipital lobe and thalamus. DSA showed that the arteriovenous fistula was classified as Borden type Ⅲ or Cognard type Ⅳ in 36 cases (88%). Twenty-nine patients (71%) underwent a single surgical procedure, while 12 cases (29%) underwent combined surgical or other treatments. Overall, 37 patients (90%) achieved angiographically documented obliteration of the fistula and 39 patients (95%) experienced good or excellent outcomes.Conclusions:TDAVF often presents as cerebral parenchymal hemorrhage which is common in supratentorial region, but rare in basal ganglia region. The cause of cerebral hemorrhage in patients with hypertension may not be attributed to hypertension. Early diagnosis and intervention are of great significance to improve the prognosis of patients.

Influencing factors of adult thyroid volume in Lanzhou City / 中华地方病学杂志

Objective:To investigate the thyroid volume of adults in Lanzhou City, and analyze its influencing factors.Methods:In June 2016, according to the principle of multi-stage stratified cluster sampling, Han residents aged 18 and above in Chengguan, Xigu and Qilihe districts of Lanzhou City who had lived there for more than 5 years were selected as research subjects, and a portable B-ultrasound machine was used for thyroid examination. Morning urine samples of the subjects were collected to test urinary iodine; fasting venous blood samples of the subjects were collected to test serum thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb), blood lipids [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL)] and blood uric acid (Ua) levels. At the same time, body indexes systolic blood pressure (SP), diastolic blood pressure (DP), waist circumference, height and weight were measured, and the body mass index (BMI) was calculated. Multiple linear regression was used to analyze the influencing factors of thyroid volume.Results:A total of 1 009 subjects were included, aged (43.50 ± 15.16) years, and the thyroid volume was (8.74 ± 3.39) ml. Among them, 534 males had a thyroid volume of (9.46 ± 3.43) ml; 475 females had a thyroid volume of (7.93 ± 3.15) ml, the thyroid volume of males was larger than that of females ( t = 7.36, P < 0.01). Thyroid volume was positively correlated with age, height, weight, BMI, SP, waist circumference, LDL, Ua and TgAb ( r = 0.07, 0.23, 0.33, 0.27, 0.10, 0.27, 0.10, 0.08, 0.07, P < 0.05), and it was negatively correlated with thyroid nodules, TPOAb, TSH and urinary iodine ( r = - 0.16, - 0.07, - 0.10, - 0.08, P < 0.05). After multiple linear regression analysis, TSH, TPOAb, TgAb and thyroid nodules were included in the regression equation, and the standardized B values were - 0.135, - 0.065, 0.123 and - 0.197, respectively. Conclusions:The thyroid volume of males is larger than that of females in Lanzhou City. TSH, TPOAb, TgAb and thyroid nodules are influencing factors of thyroid volume.

Detection of thyroid nodules in people with abnormal lipid metabolism and related factors / 中华地方病学杂志

Objective:To investigate the detection rate and related factors of thyroid nodules in people with abnormal lipid metabolism.Methods:From September 4, 2016 to February 1, 2017, community residents living in Lanzhou City, Longnan City, Dingxi City and Linxia City of Gansu Province for more than 5 years were selected as the respondents. General data were recorded, venous blood was collected, blood lipid related biochemical indexes were detected, and thyroid ultrasound was performed. By comparing the general data and biochemical indexes, the detection of abnormal lipid metabolism and thyroid nodules were analyzed, and the risk factors of thyroid nodules in people with abnormal lipid metabolism were analyzed by logistic regression.Results:Two thousand and fifty-nine residents were included in this study (1 049 males and 1 010 females). The total detection rate of thyroid nodules was 23.17% (477/2 059). The detection rate of thyroid nodules in people with abnormal lipid metabolism [34.16%(151/442)] was significantly higher than that in people with normal lipid metabolism [20.16% (326/1 617) , P < 0.01], and the detection rate of thyroid nodules of women [43.37% (85/196) ] was higher than that of men [26.83% (66/246) , P < 0.01]. Among the people with abnormal lipid metabolism, the highest detection rate of thyroid nodules was in mixed hyperlipidemia [57.14% (16/28)], followed by hypertriglyceridemia [34.59% (92/266)]. The detection rates of thyroid nodules in the groups with elevated total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels [35.16% (32/91), 34.85% (23/66)] were higher than those in the marginal elevated group [27.04%(86/318), 30.42% (73/240)] and the normal groups [21.76% (359/1 650), 21.73% (381/1 753), P < 0.05]. The results of logistic regression analysis showed that the risk factors of thyroid nodules in people with abnormal lipid metabolism were increased age, elevated fasting blood glucose (FPG), elevated blood glucose 2 hours (2 h PG) after oral glucose tolerance test (OGTT) load and elevated glycosylated hemoglobin [HbA1c, odds ratio ( OR)=1.065, 1.387, 1.866, 1.384, P < 0.05]. Conclusions:The prevalence of TN is higher in populations with abnormal lipid metabolism. The control of blood sugar and blood lipid levels may play a role in the prevention of thyroid nodules.

Mental symptoms and its influencing factors of patients with malignant tumor undergoing chemotherapy in general hospital / 中华行为医学与脑科学杂志

Objective:To estimate the mental symptoms in malignant tumor patients undergoing chemotherapy using DSM-5 cross cutting symptom measure.Methods:A total of 314 patients who undergoing chemotherapy in oncology department of Zhongshan Hospital, Fudan University who met all standards were chosen. The DSM-5 cross cutting symptom measure Level 1 Scale was used to assess the mental symptoms of the patients. SPSS 25.0 software was used for χ 2 test, Pearson correlation analysis and multiple regression analysis. Results:The most common symptoms in the patients were depressive symptoms(85/314, 27.1%), somatic symptoms (79/314, 25.2%), manic symptoms (78/314, 24.5% ) and anxiety symptoms (76/314, 24.3%). The proportion of anxiety symptoms in malignant tumor patients who were taken care of by other personnel(26/64, 40.6%) was significantly higher than that in patients who were taken care of by immediate relatives(50/250, 20.0%)(χ 2=12.23, P<0.05). Patients with unstable working conditions were more likely to have depressive symptoms (χ 2=7.64, P<0.05). There was a significant negative correlation between the patients' understanding of the disease and their scores of depressive symptoms, somatic symptoms, manic symptoms, anxiety symptoms and the total score of mental symptoms( r= -0.26, -0.15, -0.12, -0.25, -0.22, all P<0.05). In addition, the total score of mental symptoms of malignant tumor patients was significantly positively correlated with family burden and family status( r=0.11, 0.11, both P<0.05), and negatively correlated with patients' education ( r=-0.13, P<0.05). Multiple regression analysis showed that the degree of understanding of the disease( β=-0.203) and family status( β=0.197) were the influencing factors of mental symptoms of inpatients malignant tumors undergoing chemotherapy in general hospital ( F=13.653, P<0.001). Conclusion:Malignant tumor patients undergoing chemotherapy may have a variety of mental symptoms. The high incidence mainly includes depressive symptoms, somatic symptoms, manic symptoms and anxiety symptoms. The understanding of the patients to the disease and family situation are the main influencing factors.

STUDY DESIGN: Retrospective case series. PURPOSE: To investigate the clinical efficacy and feasibility of one-stage anterolateral debridement, bone grafting, and internal fixation for treating lumbosacral tuberculosis. OVERVIEW OF LITERATURE: There has been no consensus regarding the optimal means of treating lumbosacral tuberculosis. The one-stage anterolateral extraperitoneal approach for radical debridement, bone grafting, and internal fixation for treating lumbosacral tuberculosis is rare in literature. METHODS: Twenty-one patients with lumbosacral tuberculosis were retrospectively analyzed. All patients underwent the surgery of anterolateral debridement after regularly antituberculous drugs therapy. We evaluated the erythrocyte sedimentation rate, C-reactive protein, radiography, computed tomography, magnetic resonance imaging, visual analogue score, and Oswestry disability index before and after surgery. RESULTS: All patients completed a follow-up survey 9–48 months after surgery. All patients' wounds healed well without chronic infection or sinus formation, and all patients with low-back pain reported relief after surgery. All cases had no tuberculosis recurrence. Solid bony fusion was achieved within 6–12 months. At final follow-up, evaluated the erythrocyte sedimentation rate decreased from 38.1±12.5 to 11.3±7.1 mm/hr, C-reactive protein decreased from 6.2±4.2 to 1.6±1.3 mg/dL, the visual analog scale score decreased from 4.6±1.1 to 1.4±1.0, the Oswestry disability index score decreased from 50.2%±11.9% to 13.0%±6.6%, and the lumbosacral angle increased from 20.0°±4.8° to 29.0°±3.9° (p<0.05). CONCLUSIONS: One-stage anterolateral debridement, bone grafting, and internal instrument fixation for treating lumbosacral tuberculosis is safe and effective.

BACKGROUND:Human-mammal chimeric liver chimera has been a vital significance for the proliferation and differentiation of bone marrow mesenchymal stem cells. OBJECTIVE:To establish an animal model of human-rhesus chimeric liver using adult bone marrow mesenchymal stem cells. METHODS:Adult bone marrow mesenchymal stem cells were isolated, purified and cultured for the sixth generation. The number of bone marrow mesenchymal stem cells was no less than 5×108. Bone marrow mesenchymal stem cells labeled with green fluorescent protein were transplanted into the liver of the embryo rhesus with pregnancy of 10 weeks under guided by type-B ultrasound. At the 1st and 3rd months of birth, the liver tissue of the infant rhesus was taken for biopsy. After routine pathological section, histological specimens were observed under fluorescence microscope to confirm if there were adult bone marrow mesenchymal stem cells positive for green fluorescent protein and their distribution, and detected by immunohistochemical staining to identify if human albumin expressed in the liver of infant rhesus. RESULTS AND CONCLUSION:Fluorescence microscope observation indicated that at the 1st and 3rd months after birth, there were surviving bone marrow mesenchymal stem cells derived from human with green fluorescence in the liver of infant rhesus, and these cells migrated to form more concentrated distribution. The immunohistochemical results demonstrated that functional liver cells expressing human albumin were observed in the liver of infant rhesus at the 1st and 3rd months after birth, and their distribution was in accordance with bone marrow mesenchymal stem cells with green fluorescence. Human-rhesus chimeric liver can be established using adult bone marrow mesenchymal stem cells, which can generate functional liver cells in the liver of infant rhesus.
