Objective To study the expression of SARS-associated coronavirus nucleocapsid(N) gene in Pichia pastoris and to obtain recombinant N protein with good biological activity.Methods The gene encoding the full N protein of SARS-CoV was amplified by PCR and cloned into Pichia pastoris expression vector pPICZA.The recombinant expression plasmid pPICZA/N was transformed into X-33,KM71H and GS115. The positive insert transformants were screened,cultured and induced by methanol.The recombinant protein was further purified with Ni affinity chromatography.Antigen activity was detected with anti-N monoclonal antibody,polyclonal antibody and sera from SRAS patients.Results SDS-PAGE and immunological analysis demonstrated that only Pichia pastoris transformants KM71H/pPICZA/N and X-33/pPICZA/N expressed Mr 70 000 fusion protein with special antigenicity.Conclusion SARS-CoV N protein expression in Pichia pastoris has been achieved,establishing the basis for further study of biological and immunological function of N antigen.

BACKGROUND:With the development of sports medicine and research of patel ofemoral disorder, patel a alta has been paid increasing attention as the exact pathogenesis of patel ofemoral disorder. There are many radiographic measurement indexes of patel a alta. A large number of clinicians and radiography physicians are trying to diagnose and treat this disease as early as possible.
OBJECTIVE:To review the radiographic measurement and research progress of patel a alta, find out the advantages and disadvantages of different indexes, and look into the future development prospects.
METHODS:A computer-based online search of Pubmed and CNKI databases between 1989 and 2013 was performed for articles addressing radiographic diagnose and measurement patel a alta. The key words were“patel a alta, patel a height, measurement, diagnosis”in English and“patel a alta, patel a height, patel a position, diagnosis, measurement”in Chinese.
RESULTS AND CONCLUSION:Now there are many measurement indexes of patel a alta and they are divided into two groups:indirect index and direct index. The indirect index measures the relative location of patel a and tibia, such as Insal-Salvat index, Blackburne-Peel index, and Caton-Deschamps index. The direct index measures the relative location of patel a and femur, such as patel otrochlear index, and patel ophyseal index. The latest study indicates that the biomechanics of patel ofemoral joint is the key to understand the pathogenesis of patel ofemoral disorder. As the MRI technique develops, direct index for the location of articular cartilage of patel ofemoral joint, such as patel otrochlear index, seems to be the best measurement to patel a alta. However we stil have many problems in the study of patel otrochlear index.

Objective To study the nursing methods of gastrointestinal cancer patients undergoing continuous hyperthermic peritoneal peffusion chemotherapy (CHPPC) in the peri-operative period.Methods A total of 126 patients with gastrointestinal cancer underwent continuous hyperthermic peritoneal perfusion chemotherapy,and nursing care was implemented continuously,comprehensively and individually.Results All of the patients underwent continuous hyperthermic peritoneal perfusion chemotherapy successfully,without any complication occurred.Conclusions Intensive and effective nursing care is helpful to carry out continuous hyperthermic peritoneal perfusion chemotherapy safely,and avoid the complications.

This paper studied the usage and impact of the theory in hospital development.Based on such,special manifestations behind the marginal diminishing effect are taken into consideration to grasp particular demands and requirements of health,and to look for a positive role and a progressive increase of the marginal utility.Furthermore,the explorations in hospitals,such as technical innovations,structure optimizations and management breakthroughs,as well as the experimental and practical construction of micro-economic administrative mechanism in clinical departments were discussed in the text.It has been demonstrated in practice that the practice has a significant effect on the prevention of marginal diminishing utility and an essential reference on hospital transformational development.

Left atrial volume index (LAVI) is related to systolic and diastolic function of heart .It can reflect the se‐verity of left atrial dilation and heart failure (HF) ,and is a powerful index predicting poor prognosis of HF .This article made a review on the relationship among cardiac function ,prognosis and LAVI in HF patients ,and the diag‐nostic value of LAVI for HF patients .

Pancreatic cancer is a common malignant neoplasm of the pancreas with an extremely high mortality.Currently,the early diagno-sis of pancreatic cancer is still not ideal.Attention should be paid to some clinical warning symptoms,such as unexplained abdominal and back pain,jaundice,and unexpected diabetes.Additionally,the combined use of CA19-9,CEA,and other tumor markers,the attention to biochemical indicators,the detection of mutation in KAI1 or p53 gene,and the exploration of the value of miRNA in clinical diagnosis are of great significance.On the other hand,ultrasound,CT,MRCP,ERCP,PET-CT,and other imaging methods,as well as effective col-lection of cytology specimens,should be performed.Thus,there is hope for the early diagnosis of pancreatic cancer.

Objective To observe the effects of repeated low and high-frequency transcranial magnetic stimulation (rTMS) on neuropathic pain and the expression of specific activation markers of astrocytes and glial fibrillary acidic protein (GFAP) in the lumbar spinal cord.Methods Twenty-eight male Sprague-Dawley rats were randomly divided into a sham-operated group,a sham-rTMS group,a 1 Hz group and a 20 Hz group,with 7 in each group.The rats in the sham-operated group had their sciatic nerve exposed without ligation,while the other groups underwent sciatic nerve ligation to induce neuropathic pain.Three days after the operation,rTMS was applied to the primary motor cortex (M1) contralateral to the pain once a day for 10 consecutive days.Pain-related behavior and thermal pain response were tested before the operation and before and after the course of rTMS therapy.The expression of GFAP in the lumbar spinal cord was examined.Results All of the rats which underwent sciatic nerve ligation showed pain-related behavior and significantly decreasing thermal pain latency compared with the sham-operated group.After the rTMS therapy the thermal hyperalgia was significantly attenuated in the 20 Hz group but not in the 1 Hz group compared with the sham-rTMS group.The expression of GFAP in the dorsal horn of the lumbar spinal cord ipsilateral to the neuropathic pain was significantly increased in the sham-rTMS group and the 1 Hz group compared with the sham-operated group.Compared with the sham-rTMS group,GFAP levels were significantly lower in the 20 Hz group but not in the 1 Hz group.The pain relief in the 20 Hz group was negatively related to the expression of GFAP.Conclusions Neuropathic pain induced by peripheral nerve injury is associated with increased activity and proliferation of astrocytes in the dorsal horns of the spinal cord.High-frequency rTMS can relieve neuropathic pain through inhibiting the activity and proliferation of astrocytes in the dorsal horns,but low-frequency rTMS has no clinically significant effect.

OBJECTIVE:To investigate the hemostatic effect and safety of hemocoagulase in radical gastrectomy.METHODS:60 cases with gastric cancer were divided on average into 2 groups.Therapy group received hemocoagulase 2 KU during and after operation,and control group received dicynone 0.5 g and aminomethylbenzoic acid 0.2 g during and after operation.Intraoperative blood loss and amount of blood drainage at 6 h and 24 h after operation were observed.The value of D-dimer was monitored after operation.RESULTS:Intraoperative blood loss and amount of blood drainage at 6 h and 24 h after operation in therapy group were less than in control group (P
