By describing this case and screening of the literature, we explain the various diagnostic and therapeutic methods, both medical and surgical.

We report the image findings on ultra- sonography and computed tomography ( CT) of huge HAML. METHOD; The clinical, imaging and pathological data of a case of HAML were retrospectively collected and ana- lyzed. RESULTS; A huge heterogeneous hyperecho mass with anecho and hypoecho areas inside was found in the left he- patic lobe on ultrasonography. Color Doppler showed blood flow and arterial spectrum in it. CT scan showed a huge heterogeneous solid mass in the left lobe of the liver, with a low density and hypervascular area in arterial phase. The serum tumor marks were all negative. Ultrasound- guided biopsy was taken twice before resection and both showed necrosis tissue and reaction of inflammatory cells. Postoperative pathological results showed that the tumor was composed of epithelioid smooth muscle cells, thick- walled blood vessels and a few adipose cells with necrosis. The immunohistochemistry results showed appea-rance of typical HAML, with HMB-45 positive and alpha fetopro- tein (AFP) negative. CONCLUSIONS: Preoperative diagnosis of HAML relies on combination of CT, MRI and ultrasonography. Our case of HAML showed heterogeneous hyperecho image on ultra- sonography. Ultrasound-guided biopsy combined with morphological manifestation and specimen examination for HMB-45 may be helpful in the diagnosis of HAML.展开更多

The aim of this study was to evaluate the ultrasound (US) features of patients with MAGI and acquired premature ejaculation (APE) associated (MAGI-APEpos). US evaluation of 50 MAGI-APEpos patients compared to 50 patients with MAGI without PE (MAGI-PEneg) which represent the control group. The diagnosis of APE was made through the evaluation of Intravaginal ejaculation latency time (IELT) and confirmed with the questionnaire PEDT (Premature Ejaculation Diagnostic Tool). The main outcome measure was represented by the frequency of US criteria suggestive of P (prostatitis), V (vesiculitis), and E (epididymitis) in MAGI-APEpos and MAGI-PEneg patients. MAGI-APEpos patients showed a total number of US criteria significantly higher compared to MAGI-PEneg patients. MAGI-APEpos showed a higher frequency of US criteria of V and E (complicated forms of MAGI). Finally, in MAGI-APEpos group, it was found a positive relationship between the anteroposterior diameter (APD) of the caudal tract of the epididymis and the APD of the seminal vesicles, as well as between both diameters and the PEDT score. MAGI-APEpos patients have a peculiar US characterization compared to MAGI-PEneg patients. According to these results, US evaluation of the epididymal and of the prostato vesicular tract should be considered in the practical clinical approach of patients with MAGI and APE. In particular, it could be a SUDDort for a possible Dathoahysiological interpretation of this clinical problem in these patients.展开更多

Methods: Forty cases were randomly allocated to a treatment group and a control group, 20 cases in each group. Cases in the treatment group were treated with acupuncture, while cases in the control group were treated with oral Sibelium. After that, the changes of cerebral blood flow were observed before and after treatment. Results: There was significant difference in clinical efficacies between two groups (P〈0.05). There were also significant differences in arterial blood flow velocities of before and after treatment. Acupuncture can produce substantial differences (P〈0.05) in blood flow velocities of vertebral artery (VA), middle cerebral artery (MCA) and anterior cerebral artery (ACA) during an increased flow rate. It can also produce statistical differences in blood flow velocities of VA during a decreased flow rate (P〈0.05). Conclusion: Acupuncture can effectively alleviate the pain of migraine sufferers and exert a two-way regulation on the cerebral blood flow.展开更多

文摘Objective: To observe the clinical efficacy of acupuncture treatment for migraine. Methods: Forty cases were randomly allocated to a treatment group and a control group, 20 cases in each group. Cases in the treatment group were treated with acupuncture, while cases in the control group were treated with oral Sibelium. After that, the changes of cerebral blood flow were observed before and after treatment. Results: There was significant difference in clinical efficacies between two groups (P〈0.05). There were also significant differences in arterial blood flow velocities of before and after treatment. Acupuncture can produce substantial differences (P〈0.05) in blood flow velocities of vertebral artery (VA), middle cerebral artery (MCA) and anterior cerebral artery (ACA) during an increased flow rate. It can also produce statistical differences in blood flow velocities of VA during a decreased flow rate (P〈0.05). Conclusion: Acupuncture can effectively alleviate the pain of migraine sufferers and exert a two-way regulation on the cerebral blood flow.
