Objective To summarize and analyze the clinical features,imaging manifestations,pathological characteristics,treatment approaches,and prognosis of adrenal anastomotic hemangioma(AH),so as to enhance the clinical understanding of this disease.Methods A retrospective analysis was conducted on 3 adrenal AH patients treated in Tongji Hospital during Jan.2012 and Dec.2024.Relevant literature was reviewed.Results All patients were male,aged 34-56 years,with a maximum tumor diameter of 2.0-5.0 cm.All tumors were solitary.No patients presented with special clinical manifestations.Biochemical tests indicated tumors with no endocrine function.Contrast-enhanced computed tomography showed circular mixed density shadows with uneven edge enhancement.Two patients underwent laparoscopic partial adrenal resection,and one patient received robot-assisted laparoscopic partial adrenal resection.Postoperative pathological results of all three cases indicated AH.Immunohistochemistry showed CD31(+),CD34(+),and ERG(+).No recurrence was found in a postoperative follow-up of 1-45 months.A total of 22 cases of adrenal AH were reported in the literature and our center,with onset age ranging from 34 to 83 years.The patients included 17 males and 5 females,with a maximum tumor diameter of 0.6-8.8 cm.Among them,2 cases were multifocal and the tumors were located in the kidneys,beside kidneys,or in the inferior vena cava.Two cases showed clinical manifestations of lower back pain.During the follow-up of 156 months,no recurrence or metastasis was observed.Conclusion Adrenal AH is a rare benign tumor,which mainly occurs in middle-aged and elderly people with no clinical symptoms and endocrine function.Imaging can easily mistake it for pheochromocytoma or well differentiated vascular sarcoma,and the diagnosis mainly relies on pathological examination.It should be distinguished from pheochromocytoma and well differentiated vascular sarcoma.Surgery is the main treatment method and the prognosis is good.

OBJECTIVETo observe the effects of acupuncture on mRNA of the neurotransmitter serotonin transporter (5-HTT), 5-HTreceptor (5-HTR), norepinephrineα2 receptor (NEαR) in brain tissue in rats with post-stroke depression.

METHODSForty male SD rats were randomly divided into a normal group, a model group, a medication group and an acupuncture group, 10 rats in each one. The model of post-stroke depression was established by occlusion of middle cerebral artery and chronic unpredictable mild stress method. After model was successfully established, the rats in the normal group and model group received no treatment; the rats in medication group were treated with intragastric administration of fluoxetine (2 mg/kg); the rats in acupuncture group were treated with acupuncture at "Baihui" (GV 20), "Fengfu" (GV 16), "Shenmen" (HT 7) and "Taichong" (LR 3) for 20 min, during which manual stimulation was given once, once a day, 7 days as one course, and totally 3 courses were given with an interval of one day between courses. The changes of rat behavior and 5-HT, NE were observed after intervention; the RT-PCR method was applied to observe the mRNA of 5-HTT, 5-HTR, NEαR in hippocampus, raphe nucleus and locus coeruleus.

RESULTSAfter treatment, compared with the normal group, the Zea Longa score in the model group was increased, while sugar water consumption, the number of horizontal and vertical movement of open-field test was reduced (all<0.01); compared with the model group, the Zea Longa score in the medication group and acupuncture group was reduced, while sugar water consumption, the number of horizontal and vertical movement of open-field test were increased (<0.01,<0.05); compared between the medication group and acupuncture group, the behavior changes were not significantly different (all>0.05). After treatment, compared with the normal group, the content of 5-HT and NE in brain tissue and mRNA expression of 5-HTT, 5-HTR in hippocampus, raphe nucleus and locus coeruleus in the model group were reduced (all<0.01), but the mRNA expression of NEαR was increased (<0.01);compared with the model group, the content of 5-HT and NE in brain tissue and mRNA expression of 5-HTT, 5-HTR in hippocampus, raphe nucleus and locus coeruleus in the medication group and acupuncture group were increased (<0.01,<0.05), while the mRNA expression of NEαR was reduced (all<0.01). The differences between medication group and acupuncture group were not significantly different (all>0.05).

CONCLUSIONSAcupuncture could significantly improve behavioral change in rats with post-stroke depression, which may be related to the regulation of 5-HT, NE in cerebral cortex as well as mRNA expressions of 5-HTT, 5-HTR, NEαR in hippocampus, raphe nucleus and locus coeruleus.

AIM: To test and verify the effect of Shexiang Baoxin Pills(SXBXW) on treating acute vertigo. METHODS: Sixty patients with acute vertigo were randomly assigned to the treatment group(40 cases) and the control group(20 cases).The treatment group was given four pills of SXBXW by sublingually. The control group was drip-fed Betahistine Hydrochloride and Sodium Injection 250 mL. Both groups were drip-fed normal saline injection 250 mL plus Vitamine B_6 0.2g at the same time. RESULTS: After three hours of observation, both the drugs could significantly reduce the sympton of acute vertigo, and its therapeutic efficacies were similar. CONCLUSION: SXBXW has obvious therapeutic efficacy and less side effect.

Objective To evaluate the clinical value of 9 9 Tc m-HL91 as a tumor positive imaging agent in diagnosis of pulmonary neopl asms. Methods We performed 2 h,4 h planar and 4 h tomogr aphy fusion imaging after injection of HL91 on 42 patients with high probability of pulmonary cancer. Tumor-to-normal tissue background (T/N) ratios were meas ured for all scans. Results T/N ratios at 2 h,4 h planar and 4 h transectional imaging in malignant group were 1.50? 0.17 ,1.71?0.22 and 2.72?0.75, respectively; while in benign group, they were 1.21?0.10,1.25 ?0.22 and 1.49?0.36, respectively. 4 h delay T/N ratios in malignant group we re obviously higher than 2 h ( P 0.05). There were no remarkable differences of T/N ra tios in different phases and histological types of lung carcinoma. Using maligna nt transection ratio ( -1s ) as diagnostic threshold, the sensitivity , specificity and accuracy were 84.85% , 88.89% and 85.71% , respectiv ely. Using transection ratio( +1s ) of benign group as diagnostic th reshold , the sensitivity, specificity and accuracy were 90.91%, 88.89% and 95.2 4%,respectively. Conclusion The results indicate that as a tumor positive imaging agent 99 Tc m-HL91 is useful in diagosising pulmon ary neoplasms.

Objective To certify whether 99mTc-HL91 can be trapped in ischemic myocardium prominently for clinical imaging. Methods The model of myocardial ischemia in rabbits was prepared and the distribution of 99mTc-HL91 was observed. The distribution of 99mTc-HL91 in the whole body was also observed. Results The myocardium of the left ventricle supplied by LCX was ischemic according to the change of electrical physiology and the results of NBT dying. The radioactivity in the myocardium of left ventricle supplied by LCX was higher than that supplied by LAD. LCX/LAD: 120 min, 2.57; 180 min, 3.45. 99mTc-HL91 was mostly distributed in the liver and kidney, next, the stomach and intestine. It was excreted through urination and defecation. There was little radioactivity in the heart and lungs and it eliminated quickly. 99mTc-HL91 was eliminated quickly from blood, too. Conclusion Ischemic myocardium can trap 99mTc-HL91 more significantly and relatively prominently at 180 minutes of post-injection. 99mTc-HL91 can be used in myocardial hypoxia imaging.
