Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Objective To analyze the difference in computed tomography (CT) imaging findings between pulmonary alveolar pneumoconiosis Methods proteinosis (PAP) and occupational pneumoconiosis (hereinafter referred to as ). A total of 44 patients with PAP (PAP group) and 44 patients with pneumoconiosis (pneumoconiosis group) were selected as study subjects using Results convenient sampling method. The CT images of these two groups were comparatively analyzed. The detection rates of - - pulmonary CT pattern changes such as map like performance, ground glass opacity, paving stone sign and sphenoid wing like vs vs changes of pulmonary hilum in the PAP group were higher than those in the pneumoconiosis group (77.3% 0.0%, 75.0% vs vs P 2.3%, 56.8% 0.0%, 18.2% 0.0%, all <0.01); the detection rates of lymphadenopathy and calcification of pulmonary hilum, small pulmonary nodules, emphysema and interlobular septal thickening were lower in the PAP group than those in the vs vs vs vs P Conclusion pneumoconiosis group (34.1% 100.0%, 4.5% 100.0%, 2.3% 45.4%, 0.0% 22.7%, all <0.01). Paving - stone sign and map like performance were most commonly found in the CT imaging of patients with PAP, and it is uncommon in pneumoconiosis. These changes could be used as the CT differential diagnosis of the two diseases.

Objective: To investigate the effect of combining acupuncture and auricular point sticking on heart rate variability (HRV) in patients with post-stroke depression (PSD). Methods: A total of 80 cases with PSD were randomized into a treatment group and a control group. The control group was intervened by oral administration of paroxetine hydrochloride, whereas the treatment group received acupuncture plus auricular point sticking base on the same oral administration. The Hamilton depression rating scale (HAMD) and HRV were measured before and after treatment in both groups. Results: The individual and global scores of HAMD significantly dropped after 8 weeks of treatment in both groups (all P<0.05). In the treatment group, anxiety/somatization factor, sleep disturbance, hopelessness factor, cognition factor and global score were significantly different from those in the control group (all P<0.05). The 24 h standard deviation of all normal-to-normal R-R interval (SDNN), standard deviation of 5-minute average of normal R-R intervals (SDANN), root mean square of successive differences (RMSSD), percent of differences between adjacent normal R-R intervals >50 ms (PNN50) and high frequency (HF) were increased while low frequency (LF) and LF/HF decreased significantly after 8 weeks of treatment in both groups (P<0.05). All items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Combining acupuncture and auricular point sticking can enhance the conventional medical treatment for HRV in patients with PSD.

BACKGROUND: Stellate ganglion block has the ability to improve the imbalance of the autonomic nervous system in perimenopausal syndrome. Lumbosacral plexus is an automatic nervous block, and exerts similar effects with stellate ganglion block. OBJECTIVE: To investigate the effect of lumbosacral plexus block on the serum level of hormones and histology of the ovary in rabbits, thus providing a new treatment strategy for perimenopausal syndrome. METHODS: This was a randomized controlled animal experiment, which was finished at the Animal Center of Guiyang Medical Unversity, China. The healthy rabbits were randomly divided into experimental and control groups, and underwent lumbosacral plexus block by injecting 0.5 mg of vitamin B12, 100 mg of lidocaine and 10 mL of normal saline into the psoas compartment, and the same volume of normal saline, respectively. The effect of lumbosacral plexus block on the serum levels of hormones (estradiol, gonadotropin releasing hormone, follicle-stimulating hormone and luteinizing hormone) at rabbit proestrus, estrus and metaestrus were observed, respectively. The pathological changes of the ovary in a complete estrus cycle were observed. The relationship between the treatment time of lumbosacral plexus block and the levels of hormones was investigated after 1, 3 and 6 complete estrus cycles. The experimental followed the national guidelines for the Care and Use of Laboratory Animals, and Consensus author guidelines on animal ethics and welfare by the International Association for Veterinary Editors (IAVE), and prepared in accordance with the Animal Research: Reporting of In Vivo Experiments Guidelines (ARRIVE Guidelines). RESULTS AND CONCLUSION: Lumbosacral plexus block can increase the serum level of estrogen, reduce the serum levels of follicle-stimulating hormone and luteinizing hormone, and regulate the hypothalamic-pituitary-ovary axis function. Presumably, it may be used as a treatment method or adjuvant therapy of perimenopausal syndrome. Future experiments are needed to explore the effect of lumbosacral plexus block on the serum levels of hormones in a rabbit after oophorectomy to determine whether it exhibits the same effect on ovarian failure.

Objective To investigate the interactional roles corticosterone and stress played during the PTSD-Like memory impairment.Methods First we established the model of PTSD-like memory using three levels of electric shock:0 mA,0.8 mA and 1.4 mA.The freezing time percent of each group were calculated 24 hours later in order to find which group of rats obtained the PTSD-like memory,and generalizing tests was used to verify it.After the model was established,rats received adrenalectomy (ADX) were operated bilaterally in order to investigate the effect of corticosterone and fed with corticosterone in the drinking water 7 days before fear conditioning.These rats were divided into four groups:control group (no corticosterone supplement,0 mA shock),Cort group (corticosterone supplement,0 mA shock),shock group (no corticosterone supplement,1.4 mA shock),Cort-shock group (corticosterone supplement,1.4 mA shock).A two-way factorial analysis of variance was used to determine whether there was a significant interaction between corticosterone and shock.Results The freezing time percent of group 0.8 mA raised compared with the group 0 mA,whereas the freezing time percent of group 1.4 mA showed reversely and the generalizing effects appeared,compared with group 0.8 mA.In two-way factorial analysis design,the freezing time percent of Cort-shock group significantly increased (P＜0.05) compared with other groups,and there was no significant variance among the other groups.Corticosterone (F=6.464,P＜0.05) and stress (F=53.419,P ＜0.01) played parts in the formation of PTSD-like memory impairment,and they interacted with each other (F=11.580,P＜0.05).Conclusion PTSD-like memory impairment can be induced on rats with high (1.4 mA) electrical shock,and they have interactional effect with each other in the process.

Objectives To evaluate pediatric neck masses with magnetic resonance imaging (MRI). Methods In this retrospective study, 140 children with neck masses underwent MRI were collected from May 2006 to December 2013. Of them 34 cases went through pathological examinations. The results of MRI diagnosis and pathology were compared in 34 cases. Results In 140 children with neck masses diagnosed by MRI, 103 (73.6%) cases were benign lesions, including 62 vascular malformations, 30 hemangiomas, then cysts, hamartoma, infectious lumps etc., 29 (20.7%) were malignant tumors, including 22 lymphomas, 3 rhabdomyosarcomas, 3 Langerhans cell histiocytosis, 1 neuroblastoma, and 8 (5.7%) cases were undeter-mined masses. Four in 103 cases with benign lesions were performed by pathological examination and all had been con-firmed. Tewenty-five in 29 cases with malignant tumors were performed by pathological examination and 22 cases had been confirmed. Conclusion MRI can help to diagnose the pediatric neck masses and to guide the treatment and follow-up.
