To investigate the cause, clinical features, differential diagnosis and treatment of adrenal hematoma, 4 cases were studied retrospectively. Chinese literature was reviewed. There were 4 cases diagnosed as adrenal hematoma pathologically among 282 cases of adrenalectomy in Chinese PLA General Hospital. Two cases were suspected as adrenal adenoma and the others were found incidentally during nephrectomy. Forty six cases of hematoma were reported in 7 Chinese articles since 1979. 26 1%(12/46)were misdiagnosed as adenoma for surgical treatment and 73 9%(34/46)were followed up. It is very important to have sound knowledge to make a correct diagnosis of adrenal hematoma. It is helpful to inquire the case history in detail and to do B type ultrasound repeatedly, CT scanning or MRI with contrast. Follow up is reasonable if it is not suspected to have malignant or hyperfunctioning adenoma.

As the development of hospital information systems in the third-tier hospitals of the first grade in China gradually deepens, there has appeared an urgent need to formulate standards for the management of such systems. The paper offers proposals for the structure, composition and main responsibilities of the centers for hospital information management, posts setting and post responsibilities in the centers, the number of allocated personnel in the centers and the number of personnel required for various posts, and management standards and operating procedures in the centers.

By systematically combing the records of Bladder Meridian of Foot-Taiyang from medical literatures of Zu Bi Shi Yi Mai Jiu Jing (Maxibustion Canon of Foot and Arm), Yin Yang Shi Yi Mai Jiu Jing (Maxibustion Canon of Ying and Yang), Ling Shu Jing Mai (Meridians, a chapter of Miraculous Pivot), Zhen Jiu Jia Yi Jing (A-B Classic of Acupuncture and Moxibustion), Jiu Jing Tu (Illustration of Moxibustion) from Dunhuang, it can be found that the formation and development of theory of main and collateral channels is a long-term dynamic process containing constantly summing up the experiences. The record about only the 2.3 inch one-line loop route carved out beside the posterior midline of dorsal lumbosacral portion by Bladder Meridian Foot-Taiyang may be a positioning mode of acupoint exclusively used by moxibustion and summed up by people good at moxibustion therapy using their clinical experience. In addition, thoughts that the heavy-moxibustion is a good method for difficult miscellaneous diseases (especially for the serious illnesses after attacked by wind and cold pathogens) may be included.

In order to explore the clinical feature, diagnosis and differential diagnosis of adrenal incidentalomas, we reviewed 98 cases of adrenal incidentalomas for which adrenalectomy was performed in our hospital from 1993 to 2002. It was found that the average age of the patients was 48 years old, 16 cases (16 3%) had no specific symptoms, and others were incidentally diagnosed. Of the 98 cases, 18 (18 4%) were malignant lesions, including 8 metastatic cancers, 8 adrenal carcinomas and 4 lymphangioma, and 80 were benign lesions. Twenty one cases were functioning adrenal adenoma. Ultrasound, CT scan, MRI or MIBG were effective methods to detect adrenal incidentalomas.

In order to investigate the distribution and diagnosis of adrenal tumors, 282 cases of patients who had undergone adrenalectomy in our hospital from March 1993 to December 2001 were reviewed. There were 147 (52 1%) women and 135 (47 9%) men, with a mean age of 43 6?13 0 (3～75) years. Of the 282 patients, 83 patients (29 4%) were operated on because of hyperaldosteronism, 59 (20 9%) pheochromocytoma, 27 (9 5%) hypercortisolism, 105 (37 2%) incidentaloma, 36 (12 8%) malignant tumors and 13 (4 6%) for other reasons. The average diameter of adrenal tumors was 4 8?3 4 (0 3～22 5)cm. The size of tumor mass was smallestin hyperaldosteronism, while the largest was malignant tumor. The conformation rate of the preoperative diagnosis and pathological findings was 65 2%.

OBJECTIVE: To study the expression of Interleukin2 (IL-2) signaling pathway related factors and Treg cell in nasal tissue of nasal polyps, so that to investigate the possible mechanism of IL-2 signaling pathway in the progress of nasal polyps and the correlation between IL-2 pathway and Treg cell. METHOD: Thirty patients were enrolled for study, including the patients with nasal polyps and those with only deviated nasal septum as normal control. The nasal polyps tissue and the turbinate mucosa of the patients were collected during surgery. The expression levels of IL-2 and IL-2R were measured by means of ELISA. The level of pSTAT5 was evaluated by Western blot. We measured the level of Foxp3 mRNA in the tissue by real-time PCR, and the proportion of Treg cells was evaluated by flow cytometry. Finally. we analyzed the correlation between IL-2 pathway related factors and Treg cells in nasal polyps. RESULT: The expression levels of IL-2. IL-2R and pSTAT5 were significantly decreased in the nasal polyps compared with normal control (P < 0.05), and the level of Foxp3 mRNA and proportion of Treg cells in patients with nasal polyps were significantly lower than in normal control (P < 0.05). Moreover, there was positive correlation between the levels of IL-2 pathway related factors and the levels of Foxp3 mRNA and Treg cells proportion in nasal polyps. CONCLUSION The activated state of IL-2 signaling pathway got changed in nasal polyps tissue, the level of which was positively correlated with the expression of Treg cells, indicating that the IL-2 signaling pathway may play a crucial role in the development of nasal polyps, and the decreased level of Treg cells in nasal polyps may result from the downregulation of IL-2 signaling pathway.

Neuron is the basic unit of the biological neural system. The Hodgkin-Huxley (HH) model is one of the most realistic neuron models on the electrophysiological characteristic description of neuron. Hardware implementation of neuron could provide new research ideas to clinical treatment of spinal cord injury, bionics and artificial intelligence. Based on the HH model neuron and the DSP Builder technology, in the present study, a single HH model neuron hardware implementation was completed in Field Programmable Gate Array (FPGA). The neuron implemented in FPGA was stimulated by different types of current, the action potential response characteristics were analyzed, and the correlation coefficient between numerical simulation result and hardware implementation result were calculated. The results showed that neuronal action potential response of FPGA was highly consistent with numerical simulation result. This work lays the foundation for hardware implementation of neural network.
