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.

The proto-oncogene, c-kit gene, widely expresses on the mast cell, melanoeyte, haemopoietic stem cell, intestinal cell of cajal and germoeyte. Recent researches have revealed the relationship between the e-kit gene and the carcinogenesis, proliferation, infiltration and metastasis of some malignant tumor. This article aimed to make a review of its biological function, lab and clinical research advancement in the digestive tract tumor.

Stem cells are those with long-term self-renewal and produce differentiated cells at least one end of the cell capacity. Stem cell transplantation can be used for the treatment of many kind of liver diseases which includes acute liver failure, inherited metabolic liver diseases, as well as end-stage liver disease. This Article summarizes the types of stem cell types applied for treatment of liver diseases, stem cell tracing technology, as well as the clinical application of stem cells. It also discusses the problems existed and the research focus.

To support the ongoing health reform in China,Chongqing municipal government made the decision in 2008 "Building Healthy Chongqing" ,and pinpointed for the first time regional development as a key goal.In line with this situation,the hospital proposed such hypothesis changes as from "disease hypothesis to "health hypothesis",from "illness oriented" to "capability oriented",and from "shaping development" to "adaptive development",as well as from one-sided efforts of medical staff to minimize casualty to joint efforts with patients to safeguard life and health.Focusing on these four strategic shifts,the hospital works in developing its "technical attraction,service capacity,innovation capacity,and emergency assurance capability,and management soft power",aiming at building a sustainable hospital in its development.

Objective To observe the signs of retinal vessel diameter among different clinical characteristic groups such as sex,age,BMI,the duration of DM. Methods200 diabetic patients were selected.Using face to face questionnaire survey forms filled in the questionnaire in order to collect the general situation of all subjects selected.The diameters of vessels were measured using a computer-assisted imaging program. ResultsIn type 2 diabetes mellitus,there was no significant difference in the retinal arteriolar and veular diameters between the groups with different sex.In type 2 diabetes mellitus,as age increased,both the retinal arteriolar diameters and the retinal veular diameters declined.In type 2 diabetes mellitus,there was no significant difference in the retinal arteriolar and veular diameters between the groups with different BMI.In type 2 diabetes mellitus,as the duration of DM increased,the retinal veular diameters dilated and the retinal arteriolar diameters declined.After storied in accordance with age,we can draw the sameConclusion . ConclusionIn type 2 diabetes mellitus,as the duration of DM increased,the retinal veular diameters dilated and the retinal arteriolar diameters declined.

Objective To study the influencing factors of retinal vessel caliber in type 2 diabetes mellitus and supply the elementary data for clinic. Methods Two hundred diabetic patients were involved in this study, and the vessel caliber was measured by fundus oculi color photo and computer-assisted imaging program. Biochemical indicator and blood pressure was examined and other document was achieved by questionaire. Results In type 2 diabetes mellitus, the retinal vein caliber had negative correlation with age and positive correlation with fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c) and the duration of diabetes mellitus(P < 0.01 ). The retinal arteriole caliber had negative correlation with age, blood pressure and the duration of diabetes mellitus (P < 0.01 or < 0.05 ). Conclusion The influencing factors of retinal vessel caliber in type 2 diabetes mellitus are age,FBG,HbA1c,blood pressure and the duration of diabetes mellitus.

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 .

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.
