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.

The writer observed the sural anastomotic nerve on 276 lower limbs from 138 corpses, including 11 adults and 127 new-borns (84 male, 54 females). It was found that sural anastomotic nerves are present in 219 cases (79.3%) and absent in 57 cases(20.7%). The ways of anastomosis of these nerves fall into the following four types: (1) Type A: The sural anastomotic and lateral sural cutaneous branches arise from peroneal nerve with a common trunk—108 cases (49.7%). (2) Type B: The sural anastomotic nerve is one of the terminal branches of thelateral sural cutaneous nerve—48 cases (21.9%). (3) Type C: The lateral sural cutaneous nerve arises from sural anastomoticnerve—35 cases (16%). (4) Type D: The lateral sural cutaneous and sural anastomotic branches arise separately from the common peroneal nerve—28 cases (12.8%).

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 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 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

Objective To observe the expression of matrix metalloproteinase(MMP-2, MMP-9 and vascular endothelial growth factor (VEGF) in retinoblastoma (RB) and its relationship with the differentiation and optic nerve infiltration of RB. Methods Forty paraffin specimens of pathological confirmed RB were studied. They were divided into differentiated group (15 cases) and undifferentiated group (25 cases) , optic nerve infiltration group( 13 cases) and without optic nerve infiltration group(27cases). The expression of MMP-2, MMP-9 and VEGF were detected by immunohistochemistry, their relationships with the differentiation and optic nerve infiltration were also analyzed. Results The positive rate of MMP-2, MMP-9 and VEGF expression in 40 RB cases were 52.5%, 57.5% and 72.5%respectively. The expression of MMP-2, MMP-9 and VEGF in the undifferentiated group were significantly higher than those in the differentiated group (χ2= 9. 037, 9. 253, 8. 095;P＜0. 05). The expression ofMMP-2, MMP-9 and VEGF in RB with optic nerve infiltration group were significantly higher than those in RB without optic nerve infiltration group (χ2=11.045,10. 243, 8. 956;P＜0. 05). The expression of MMP-2,MMP-9 had a positive correlation with the expression of VEGF in RB (r= 0. 126, 0. 314;P ＜ 0. 05).Conclusions MMP-2, MMP-9 and VEGF expressed in RB tumor tissues. The expression of MMP-2,MMP-9 has a positive correlation with the expression of VEGF. The levels of MMP-2, MMP-9 and VEGF expression are related to optic nerve infiltration of RB cells.
