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.

Objective To explore the decision-making processing changes of patients with cerebral infarction in different regions.Methods The patients with cerebral infarction were divided into 21 cases of frontal lobe infarction,11 cases of temporal lobe infarction,19 cases of the medial temporal lobe infarction,25 cases of basal ganglia infarction;25 cases of the anterior infarction,51 cases of the posterior infarction,62 cases of depression,64 cases of anxiety ;and there were 125 cases in normal control group.All subjects completed the test of the six kinds of choice situational problems,and used MMSE to evaluate cognitive function,the Hamilton Depression and anxiety Scale Evaluation to evaluate emotion.Results All cerebral infarction patients (CI group) and normal control group in low-risk and no-risk of loss situation(choice scenario 2),high-risk and the no-risk of gain or loss situation(choice scenario 3 and 4),high-risk and low-risk of gain or loss situation(choice scenario 5 and 6) tended to choose conservative scheme,and the selection probability of conservative scheme were obviously higher than that of the normal group,and the differences were statistically significant (P ＜ 0.05).In choice scenario 3,the basal ganglia infarction group with frontal lobe infarction group,the medial temporal lobe infarction group comparison,the conservative income scheme selection probability increased significantly,all difference were statistically significant (P ＜ 0.01,P ＜ 0.05).In choice scenario 5 of the posterior infarction group,a higher probability of conservative income scheme was selected than the anterior infarction,and the difference was statistically significant (P ＜0.05).Accompanied with depression and anxiety,the basal ganglia infarction tended to select more conservative income program than the frontal lobe infarction group and the medial temporal lobe infarction group in choice scenario 3,and the program infarction group selected a higher probability comparative differences were statistically significant (P＜ 0.01,P＜ 0.05).The posterior infarction group selected a higher probability of conservative income scheme than the anterior infarction in choice scenario 5,and the difference was statistically significant (P ＜ 0.05).Conclusion Cerebral infarction in patients exist decision-making processing abnormally,and perform as income conservative and loss risk averse.Whether associated with depression,anxiety,the basal ganglia infarction and posterior cerebral infarction patients are inclined to income conservative.

Objective In order to explore the mechanism of repetitive transcranial magnetic stimulation rTMS) on neuropathic pain,we observed the effect of different frequencies of rTMS on neuropathic pain and the expression of neuronal nitric oxide synthase (nNOS) in the dorsal root ganglion (DRG).Methods A total of 28 male Sprague-Dawley rats were used and divided into a control group,in which sham-operation was performed,and an experimental group which was further divided into a sham-rTMS group,a 1 Hz group and a 20 Hz group after successful neuropathic pain model was established by operation to ligate the left sciatic nerves,with 7 rats in each group.Three days after the operation,rTMS was applied to the primary motor cortex (M1) contralateral to the pain once dai ly for 10 consecutive days.The pain behavior and nNOS expression in the DRG were measured before and after 10 days of rTMS intervention.Results All the neuropathic pain model rats demonstrated pain-related behaviors 3 days postoperation,the mechanical pain thresholds were significantly lower than those in the control group (P ＜ 0.05).After rTMS treatment,the mechanical hyperalgsia was significantly relieved in 20 Hz group but not 1 Hz group as demonstrated by a comparison with the sham-rTMS group (P ＜ 0.05).The expression of nNOS in DRG ipsilateral to the neuropathic pain was significantly increased in sham-rTMS group and 1 Hz group (P ＜ 0.05) when compared with the control group.Meanwhile,it was shown that expression of nNOS was down-regulated in 20 Hz group but not 1 Hz group (P ＜ 0.05).The degree of pain relief in 20 Hz group was negatively correlated with the expression of nNOS in DRG (P ＜0.05).Conclusions Neuropathic pain induced by peripheral nerve injury is associated with elevated expression of nNOS in the DRG.High-frequency rTMS can relieve neuropathic pain through down-regulating the overexpression of nNOS in the DRG,but the low-frequency rTMS has no such effect.

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.

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.

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 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.
