To analyze the problems in teaching regulation of gene expression in biochemistry and investigate the teaching method which can improve the teaching of the contents.

The use of five or more drugs (polypharmacy) is common problem in the elderly,and need to attach importance.Optimization of drug treatment is a major part of medication in older adults,and also is a challenge to clinical physician.Beers Criteria provided by American Geriatrics Society (AGS) is a strong guarantee for improving medication safety in older adults

AIM: To analyse the variety of the alkaloid and volatile oil from Herba Ephedrae after mix-fring with honey. METHODS: The volatile oil was analysed by GC-MS and the total alkaloids were determined by method of Chp. RESULTS: The volatile oil changed distinctly. The contents of Isolineole、p-Cymene、D-limonene、Evcalyptol、?-Terpinen increased evidently, but the contents of Benzaldehyde、Tetramethylpyrazine、p-Vinylanisole、?-Terpineol、?-Terpineol decreased and the contents of the total alkaloids decrease as well. CONCLUSION: The study provides a new experimental basis for the process theory of Herba Ephedrae.

Objective To investigate the efficacy of MSCs infused intravenously on the regeneration of injured spinal cord and rehabilitation of its neurological function. Methods 32 SD rats, male or female, weight about 300 g for each one. MSCs were separated, cultured and purified in vitro. Surface marker of MSCs, such as CD34, CD45, CD29 and CD90 were detected by flow cytometry. The rat spinal cord injury model was prepared according to the modified Allen method. After exposure of T10 spinal cord, the T10 segment of spinal cord was injuried by a 10 g weight falling down from 5 cm high place upon a round thin copper pad which was placed on the surface of T10 segment of spinal cord. The diameter of the copper pad is 3 mm. There are 24 rats in the injuried group and 8 in the non-injuried group. The injuried group was then divided into experiment group with 14 rats and control group with 10 rats at 24 hours after preparation of models. The rats in the injuried group and non-injuried group were infused with MSCs marked by Brdu through tail vein, and the rats in control group were infused with PBS. The neurological functions of rats were evaluated at 24 hours after injury and 1, 3, 5 weeks post-infusion respectively. At the same time, the immigration, survival and differentiation of MSCs were observed. Results The MSCs were uniformly CD29, CD90 positive and CD34, CD45 negative. In vivo experiment, transplanted MSCs survived and were localized to the injured spinal cord, and a few cells expressed NSE, MAP2 post transplantation 3 to 5 weeks. Significant improvement in functional outcome in rats treated with MSCs transplantation compared to control rats. The score of BBB in the treated group was higher than that in the control group (P

Objective To evaluate the impact of the off -pump coronary artery bypass (OPCAB) on left ventricular(LV) function with transesophageal echocardiography(TEE). Methods Blood flow velocities of pulmonary vein (PV) and mitral valve (MV) were performed in 21 patients with coronary heart disease and myocardial infarction two weeks pre-OPCAB, and the left ventricular SV, CO and LVEF were measured by biplane Simpson′s method, the data were compared with the results observed one month post-OPCAB. Results The peak flow velocities of PV had significant difference between pre- and post-OPCAB(P

Objective To assess the changes of left ventricular function after off-pump coronary artery bypass (OPCAB) using Tei index. Methods Fourty-six patients of coronary artery disease, who had accepted OPCAB, were enrolled. Left ventricular ejection fraction(LVEF), E/A ratio at mitrial orifice(E/A), E deceleration time(EDT), isovolumic relaxation time(IVRT), ratio of systolic wave to diastolic wave of pulmonary vein flow(S/D) and Tei index were measured by transthoracic echocardiography before, immediate, 1 week, 1 month, 3 months and 6 months after OPCAB. Results Tei index decreased gradually as time went on after OPCAB and the differences were significant between different times(P

Objective To analyse the imaging characteristics of solitary pulmonary nodules(SPNs) with the spiral CT, and detection clinical values of the definitive diagnosis to SPNs. Methods 32 cases of SPNs were identified by spiral CT, 9 cases of them were examinated by enhancement scanning. The diffrentical imaging features were analyzed. Results 24 cases were malignant in imaging(18 cases were identified), 8 cases were benign in imaging(6 cases were identified). 15 cases of malignant SPNs by clinical identified were smooth at edge; 6 cases of benign SPNs by clinical identified. 5 cases of them were anomaly;4 cases of them were burr;2 cases of them were bronchial sign and vesiclat sign.6 cases of the SPNs were calcified. 6 cases of SPNs(9 cases with contrasting) were benign in imaging, 3 cases of them were malignant in imaging. Conclusion The differential diagnostic of SPNs is difficult by spiral CT, but enhancement scanning and epidemiology combined with spiral CT is very valuable for definitive diagnosis.

The oral glucose tolerance test,insulin release test and C peptide relea se test were carried out in 69 hypertensive patients and 55 normotensive subjects. It was found that,the concentrations of blood glucose,serum insulin and C peptide and the occurrence rates of glucose metabolic abnormality(diabetes mellitus and impaired glucose tolerance)of hypertensive group were higher than those of normotensive control group.The co-existence of hyperglycemia and hyperinsulinemia suggests the existence of insulin resistance.

Objective To analyse the pathogeny of pregnancy with virus hepatitis,the change of index of hepatic function and the clinical pathogenetic characteristic,and to explore the relationship between pregnancy and hepatitis.Methods The clinical datas of 96 pregnant patients with virus hepatitis were retrospectively analyzed,and compared with non-pregnancy during the reprodective age in the corresponding period.The pathogeny,index of hepatic function and clinical pathogenetic characteristic were compared.Results Virus hepatitis in the pregnancy were mostly type B hepatits,the morbility of hepatitis increased gradually along with the progress of pregnant weeks,the prothrombin time(PT) significantly prolonged in pregnancy with virus hepatitis,and the albumin decreased significantly,the complications of hepatocerebral disease and hepatorenal syndrome were more than non-pregnancy with virus hepatits,the incidence rate of serious hepatiti was higher than non-pregnancy with virus hepatitis(P
