Torque teno virus(TTV)is a nonenveloped virus containing a single-stranded,circular DNA genome of approximately 3.8kb.We completely synthesized the 3808 nucleotides of the TTV(SANBAN isolate)genome,which contains a hairpin structure and a GC-rich region.More than 100 overlapping oligonucleotides were chemically synthesized and assembled by polymerise chain assembly reaction(PCA),and the synthesis was completed with splicing by overlap extension(SOEing).This study establishes the methodological basis of the chemical synthesis of a viral genome for use as a live attenuated vaccine or gene therapy vector.

Objective: The current study investigate the immunological reaction state of Th1/Th2 cytokines expression in the peripheral blood mononuclear cells(PBMCs) from patients with lung cancer,and evaluate the effect of astragalus(AG) on it.Methods:The PBMCs from patients were divided into 4 groups:one group as pre-cultured group,and the other cells were cultured with 10%AG,20% AG and without AG (control group) ,respectively.The PBMC from 23 lung cancer patients as well as 19 healthy controls before and after the culture with AG were collected respectively. The Thl/Th2 cytokines expression were detected by RT-PCR considering IFN-r and IL-2 as Th1 cytokines and IL-4,IL-6,IL-10 as Th2 ones. Results:The results showed that the mRNA expression rate of IL-4,IL-6,IL-10 in PBMCs from lung cancer patients was obviously higher than that from the healthy controls( P

Objective:To compare the accuracy and safety between percutaneous kyphoplasty (PKP) positioning device and traditional positioning device which posit entry point of pedicle of vertebral arch by using the C-arm X-ray.Methods: 117 patients with spinal centrum compression fractures were divided into positioning device group (57 cases) and Kirschner wire group (60 cases) depended on the entry point marked by the preoperative C arm X-ray irradiation. To compare the excellence rate, operation time and exposure times between PKP positioning device and traditional device.Results: The positioning times of the PKP positioning device group and Kirschner wire group were (2.3±0.9)min and (6.8±1.3)min, respectively. The exposure times of the two group were 1.6 times and 4.7 times, respectively. And both of the two differences were statistical significant (t=21.062,t=18.521;P<0.05). The puncture success rates of the two group were 100%. And the excellence rates of them were 93% and 87%, respectively, and the difference also was statistical significant (x2=2.761,P>0.05).Conclusion: There are series of advantages in developed PKP positioning device, such as portable, easy and simple control, higher accuracy and safety, less positioning time and exposure times of C arm X-ray.

Objective To explore the characteristics of TCM syndromes of acute coronary syndrome(ACS). Methods Clinical data of 127 ACS patients were collected and then a database was established.After that,the distribution of syndrome patterns was analyzed.Results The incidences of the following excess syndrome patterns were in a decreasing sequence:stasis syndrome,phlegm syndrome,cold syndrome and heat syndromes.The incidence of stasis syndrome was 90.5%,which was much higher than other excess syndromes.The incidences of the following deficiency syndrome patterns were in a decreasing sequence:heart-Qi deficiency syndrome,heart-Qi exhaustion syndrome,heart-yin deficiency syndrome,heart-Qi depletion syndrome,heart-kidney deficiency syndrome and heart-blood deficiency syndrome.The incidence of heart-Qi deficiency syndrome was 75.6%,which was much higher than other deficiency syndromes.The incidences of the stasis syndrome and cold syndrome in acute myocardial infarction(AMI)were higher than those in unstable angina(UA),and the incidences of heart-Qi deficiency syndrome and heart-Qi exhaustion syndrome in AMI were higher than those in UA(P

Traditionally it has been widely accepted that our genes together with adult lifestyle factors determine our risk of developing noncommunicable diseases such as type 2 diabetes mellitus ,cardiovascular disease and obesity in lat-er life.Currently, there is substantial evidence that the early life environment plays a key role in determining our suscepti -ble to such diseases in later life .As an increased focus on the understanding of central insulin resistance , central nerve sys-tem plays an extremely important role in regulating the peripheral glucose homeostasis .Substantial studies have indicated that it may be regulated by epigenetic mechanisms .Epigenetics can be defined as the study of heritable changes in gene ex-pression that do not involve alterations in the DNA sequence .Epigenetic processes play a central role in regulating tissue specific gene expression and hence alterations in these processes can induce long -term changes in gene expression and me-tabolism which persist throughout the lifecourse .This review will focus on the epigenetic machanisms of central neuroregula-tion between early life environment and glucose metabolism in adulthood .

Nowadays the education of medical professional ethics has been obviously weakened.We can see that from some mainly expressions: There are many prejudices about medical ethics and the medical ethics education seems not very effective.But the medical professional ethics education is an important part of medical education,which directly affects the healthy development of medical and hygienic enterprise.And we must correct it,enhance it.We should inherit the good quarters of traditional medical ethics,reestablish the humanism medicine,promote virtue of medical personnel increasing,and establish the professional ethics of medical students before they become doctors.

Objective To study the effect of metoprolol combined with benazepril on cardiac structure and heart function in patients with heart failure and the treatment of hypertension in the elderly. Methods 120 cases of elderly hypertensive patients with heart failure from June 2011 to June 2015 were studied, according to the random number table method, they were randomly divided into combination group and control group.The two groups were given symptomatic and supportive therapy, the control group on the basis of conventional treatment were given antihypertensive drugs of benazepril; combination treatment group were given metoprolol on the basis of control group. After treatment, the clinical efficacy of the two groups were evaluated, the changes of cardiac structure in the two groups were recorded and analyzed before and after treatment, and the blood pressure and cardiac function were analyzed. Results The total effective rate of the combined group was 91.67%, the control group was 78.33%, there was significant difference between the two groups (χ2=4.1830, P=0.0408). After 6 months of treatment, the blood pressure, cardiac structure and 6min walking distance were significantly improved in the two groups (P<0.05). The above indicators in combination group were significantly better than those in the control group (P<0.05). The complication rate in combination group was 8.33%, 13.33% in the control group, there was no statistically significant between two groups (χ2=0.7764, P=0.3782). Conclusion Metoprolol combined with antihypertensive treatment can significantly improve the clinical efficacy of the treatment, improve the cardiac structure and function.
