Ptosis is one of the most common diseases in oculoplastics. Surgical treatment is the only way to correcting ptosis. Most of doctors paid special attention to surgical technique, rather than to some related issues of operation. Timing is crucial for ptosis surgery. Both cosmetic and function need to be considered for a success surgery, the evaluation of extraocular muscle disorder is impor- tant for surgical result and postoperative complications.

Objective: The imaging diagnosis of early liver abscess is difficult. This study is to evaluate the diagnostic value of DWI, T2WI and dynamic enhanced MR imaging for early liver abscess. Methods: DWI, T2WI and dynamic enhanced imaging scans were performed in 17 patients with 17 early liver abscesses. The signal intensities and ADC values of necrotic area, non-necrotic area and normal liver were measured and compared. Results: The ADC value of the necrotic areas of liver abscesses ([0.88±0.09] mm2/s) was significantly lower than those of normal liver ([1.31±0.12] mm2/s,P<0.05) and non-necrotic area of liver abscesses ([1.43±0.18] mm2/ s,P<0.05); there was also significant difference between the ADC values of the normal liver and non-neocrotic area (P<0.05). The necrotic areas had a hyperintensity characteristic on DWI, T2WI and a hypointensity characteristic on T1 WI; no enhancement was found on dynamic enhanced imaging. The non-necrotic areas had moderate hyperintensity on DWI, T2 WI and hypointensity on T1 WI; there was obvious enhancement on dynamic enhanced imaging. Conclusion: The early liver abscess is characterized on magnetic resonance imaging. The DWI scan is helpful for diagnosis of early liver abscess.

Objective: To investigate the value of magnetic resonance cholangiopancreatography(MRCP) in the diagnosis of pancreas divisum by comparing with endoscopic retrograde cholangiopancreatography (ERCP). Methods: The MRCP and ERCP images of 8 patients with pancreas divisum were retrospectively analyzed. The diagnostic accuracy and findings by MRCP were compared with those by ERCP. Results: MRCP had a diagnostic accuracy of 87.5%(7/8) based on the result of ERCP. ERCP displayed the dominant dorsal pancreatic ducts in all 8 cases and ventral pancreatic ducts in 6 cases; MRCP also displayed the dominant dorsal pancreatic ducts in all 8 cases, but the ventral pancreatic ducts only in 3 cases. Conclusion: As a non-invasive technique, MRCP has important clinical value in the diagnosis of pancreas divisum.

Huaier (Trametes robiniophila) has been widely used as an adjuvant drug for cancer treatment in China. The anti-cancer effect of Huaier extract has been confirmed in liver cancer, lung cancer, breast cancer, ovarian cancer, gastric cancer, and so on. The main mechanisms by which Huaier exerts an anti-neoplastic effect include inhibition of the growth and proliferation of cancer cells, induction of apoptosis of cancer cells, suppression of angiogenesis, inhibition of the invasion and migration of cancer cells, regulation of oncogenes and tumor suppressor genes expression, improving immunity, and reversal of drug resistance in cancer cells. In order to provide references for further study and clinical application on anti-tumor effect of Huaier, the latest research progress on anti-tumor effect of Huaier in recent years is summarized in this paper.

Xenotransplantation is a feasibility way of solving the shortage of human organs for transplantation. Although it is urgently needed to satisfy the demand of people and sustain the function of human organs, there are multiple hurdles existed to clinical application, such as the immune rejection between human body and the xenografts, the infection of pathogens and a series of ethic, morality and social issues. A historical retrospect of xenotransplantation was given, and then probe into the strategies according to the main problems and the actualities. Finally, the prospect in the field of xenotransplantation was showed.

Viable but non-culturable state in bacterial cells as received uncultured microorganism has be- come the fundamental research issues in medical microbiology, epidemiology, general microbial ecology and sanitation quarantine since it was put forward in 1982. When in this state, bacterium are no longer able to grow and form colonies on conventional culture media, but maintain their patheogenicity, may become latent infection escaping detection to threaten enviroment and human security. With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncul- tured microorganism in the environment. Recently, with the application of the metagenome technique, ge- netic fingerprinting technical etc, it becomes more and more popular. Simultaneously, along with this state become maturity in the laboratory. It provides a new research route for development and exploitation the uncultured microorganism.

Neuroglobin is a newly discovered member of globulin family.It has neuronprotec- tive effect under the hypoxic and ischemic conditions.In order to make the acting mechanism of globulin clear,many theories have been raised,and corresponding experiments have been done. This article reviews the latest advances systematically in this field,and puts forward possible research directions in the future.
