ABSTRACT
OBJECTIVE@#To investigate the characteristics of 18F-FDG PET/CT images of multiple myeloma secondary extramedullary infiltration in order to improve recognition.@*METHODS@#Twenty-one patients with multiple myeloma secondary extramedullary infiltration confirmed by pathology or follow-up from January 2012 to October 2020 in the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed. All the patients underwent 18F-FDG PET/CT imaging before treatment, and the PET/CT characteristics of extramedullary infiltration and bone marrow were analyzed.@*RESULTS@#Twenty-one patients included 12 males and 9 females, aged from 41 to 77 years old, with an average of 58.3±10.0; 9 cases of extramedullary infiltration involving lymph nodes; lung, stomach, spleen, and kidney were involved respectively in 2 cases; retroperitoneal, right auricle, subcutaneous nodule, and spinal meninges involvement were reported in each one case respectively. The maximum SUVmax value of extra-medullary lesions was 21.2, the minimum value was 2.1, and mean was 7.7±5.3. The maximum SUVmax value of bone marrow was 33.5, the minimum was 2.4, and mean was 6.6±3.6. There was no statistically significant difference in SUVmax value between extra-medullary lesions and bone marrow (Z=-1.195, P=0.232).@*CONCLUSION@#18F-FDG PET/CT not only has a good diagnostic value for multiple myeloma, but also a good evaluation value for secondary extramedullary infiltration, which provides reference for clinical treatment and prognosis.

Objective This study aimed to analyze the knowledge, attitude, behavior, and practice of pneumococcal vaccination in type 2 diabetes mellitus patients. Methods From January to March 2018, 3000 patients with type 2 diabetes mellitus were randomly selected from patients with type 2 diabetes registered and managed in community health service centers to participate in a questionnaire survey, using multi-stage cluster random sampling. The questionnaire included basic information, pneumococcal vaccine awareness, and pneumococcal vaccination status and inoculation intention, 2896 valid questionnaires were collected. The chi-squared test and multivariate logistic regression analysis were used to analyze the knowledge, attitude, behavior, and practice and influencing factors of pneumococcal vaccination. Results Of all the patients, 1267 (43.75％) patients with type 2 diabetes were willing to receive pneumococcal vaccination, and 23 (0.79％) patients with type 2 diabetes were vaccinated against pneumococcal, 1295(44.72％) patients with type 2 diabetes believed that patients with chronic diseases were susceptible to pneumococcal. Eight hundred seventy-seven (30.38％) patients believed that pneumococcal vaccination for chronic disease patients could reduce the risk of outpatient, hospitalization and death. Seven hundred ninety-nine (27.59％) patients believed that diabetic patients were the primary recipients of the pneumococcal vaccine. Multivariate logistic regression analysis showed that retired patients; those who thought that patients with chronic diseases were susceptible to pneumonia; those who thought that pneumococcal vaccination could reduce the risk of needing outpatient care, hospitalization, and death;and those who thought that diabetes was the priority of pneumococcal vaccination were more willing to receive pneumococcal vaccination (OR=1.442, 0.764, 1.494, 1.713, P all<0.05). Conclusion Patients with type 2 diabetes in Shenzhen have lower pneumococcal vaccine awareness, inoculation intention, and vaccination rates. Health education on the prevention of diabetes complications and pneumococcal vaccination should be promoted.
ABSTRACT
Objective To discuss the clinical application of ultrasound-guided temporary balloon occlusion in performing cesarean section for patients with pernicious placenta previa.Methods At Qujing Municipal First People's Hospital,the Interventional Department and Ultrasonography Department assisted the Obstetrics Department to accomplished cesarean section for 13 patients with pernicious placenta previa.The diagnosis of central placenta previa was confirmed by both color ultrasound and MRI in all the 13 patients.Before cesarean section,the balloons were placed in bilateral common iliac arteries or in abdominal aorta,and the balloons were inflated at the same time when the fetus was delivered so as to temporarily obstruct the target vessels.Based on the hemostatic condition,the balloon was timely withdrawn.Results Among the 13 patients,temporary abdominal aorta occlusion was employed in one and temporary bilateral common iliac artery occlusion in 12.Ultrasound-guided occlusion was successfully accomplished in 12 patients,and the average blocking time was ＜15 min.The amount of intraoperative blood loss was 800-1500 ml.Conclusion Ultrasound-guided temporary balloon occlusion before cesarean section is safe with reliable effect in treating pernicious placenta previa,it can remarkably reduce the amount of intraoperative blood loos,and it has no X-ray radiation damage,therefore,this technique is worthy of clinical application.
ABSTRACT
Objective To discuss the clinical efficacy of balloon occlusion technique in treating pernicious placenta previa.Methods Between January 2015 and March 2016,a total of 16 matcrnal patients with pernicious placenta previa,who were admitted to the Interventional Department of Qujing Municipal First People's Hospital,received balloon occlusion management to assist obstetrician in dealing with placenta previa.Central type of placenta previa with highly suspected placenta implantation were diagnosed in 15 patients by color ultrasound or MRI.Balloon catheters were placed in bilateral internal iliac arteries before cesarean section was carried out,and immediately after the fetus was taken out the balloons were inflated to temporary occlude the targeted arteries.Based on the hemostatic status the balloon catheters were timely retrieved.One patient received emergency temporary balloon occlusion of abdominal aorta,and laparotomy revealed that the placenta had penetrated to the subserosa of uterine anterior wall,and total hysterectomy had to be carried out.Results Successful balloon occlusion was achieved in all 16 patients.The mean blocking time of the artery was 15 minutes and the amount of blood loss was 300-1200 ml.Conclusion In treating pernicious placenta previa,balloon occlusion treatment before cesarean section is safe and reliable,it can significantly reduce the amount of blood loss during surgery,make quick and effective hemostasis,provide a clear surgical field for the performance of cesarean section,and,more important,save the maternal life.This effective technique has fully showed the necessity of multidisciplinary collaboration,including obstetrics,interventional radiology,etc.
ABSTRACT
Objective To discuss the clinical features diagnosis and treatment of cerebral schistosomiasis. Methods A to?tal of 166 patients with cerebral schistosomiasis were treated and their clinical data were collected and analyzed retrospectively. Results In 166 cases of cerebral schistosomiasis the confirmative diagnoses of 156 cases were diagnosed according to the clin?ical manifestation etiology immunology and auxiliary examination CT MRI .In among 74 cases were confirmed by pathologi?cal examination 10 cases were diagnosed through to the diagnostic treatment. Totally 102 patients received the oral medication of praziquantel and they all improved and discharged 14?16 days later 64 patients received the craniotomy and praziquantel medication after the operation and 48 patients significantly improved others did not improve or aggravated. There was no opera?tive mortality. Conclusions Neuroimaging and laboratory tests are valuable in the diagnosis of cerebral schistosomiasis. The praziquantel treatment is selected firstly when the diagnosis was established. However in the case of serious intracranial hyper?tension intractable epilepsy and praziquantel treatment fails the surgical treatment is required.
ABSTRACT
Objective To investigate the characteristics and diagnostic value of 18F-fluorodeoxyglucose (FDG) PET/CT in patients with secondary malignant peripheral nerve lesions. Methods 18F-FDG PET/CT studies of 8 cases of secondary malignant peripheral nerve lesions confirmed by histopathology or follow-up were analyzed retrospectively. The maximum standardized uptake value ( SUVmax ) of infiltrating peripheral nerves and contralateral normal peripheral nerves was measured and compared with their morphological appearances on CT. Paired student t-test was performed by SPSS 10.0. Results Twelve secondary malignant peripheral nerve lesions with high 18F-FDG metabolism were found in 8 cases. On PET imaging,the lesions distributed along the neurovascular tissues or intervertebral foramina with appearances resembling those of fibre bundles,radices or nodes on PET but no density differences with the surrounding soft tissue or fat planes on CT. The SUVmax was 6.86 ± 3.87. The contralateral normal peripheral nerves showed no abnormal 18F-FDG uptake with a SUVmax of 1.10 ±0.46,which was significantly different from that of the secondary malignant peripheral nerve lesions (t = 9.231,P ＜ 0.001 ). Conclusion 18 F-FDG PET/CT may be useful in locating the secondary malignant peripheral nerve lesions and in assessing its regional infiltration.
ABSTRACT
Objective To explore the changes in serum protein profiles in rats after psychological stress. Methods Twenty-four male Wistar rats were randomly divided into psychological stress group,control group and stressor group. Rats in stressor group received intermittent foot-shock. Instead of foot-shock,the rats in psychological stress group received the stimulating information from stressor group by watching,listening and smelling. Rats in control group were kept in individual cages and received no stimulation. Experiments were performed once every morning for two weeks. Serum samples of rats in both psychological stress group and control group were obtained and the changes in protein profiles were determined and statistically analyzed by Surface Enhanced Laser Desorption Ionization-Time of Flight-Mass Spectrometry (SELDI-TOF-MS) after the experiments. Results Variance analysis showed that the relative contents of proteins with M/Z values of 8870.18,6860.85,8625.13 and 11 413.91Da decreased significantly in rats of psychological stress group as compared with control group (P
