The paper suggests appling various teaching methods comprehensively to raise the students' interest and activate the class atmosphere to improve the biochemistry teaching effect on the basis of teaching materials and the level of the students during the teaching practice.

Objective To study the correlation between blood uric acid level and blood pressure among general population.Methods 1 694 healthy cases exclusion of hypertension,hyperuricemia and related diseases were enrolled in the study.The levels of blood uric acid,blood pressure,body mass index,fasting glucose,triglycerides,cholesterol were detected and compared.Results In prehypertension group,the levels of uric acid (344.5 ± 41.37)μ mol/L,shrink blood pressure (124.85 ± 7.52) mmHg,diastolic blood pressure (79.46 ± 6.62) mmHg,cholesterol (1.66 ± 1.10) mmol/L,triglycerides (4.69 ± 0.87) mmol/L,fasting plasma glucose (4.98 ± 1.01) mmol/L were significantly higher than those in the normal blood pressure group [(304.09 ± 63.75) μ mol/L,(106.12 ± 8.10) mmHg,(68.53 ± 6.26) mmHg,(1.30 ± 0.87) mmol/L,(4.52 ± 1.02) mmol/L,(4.78 ± 0.70) mmol/L] (t =15.32,49.14,34.81,7.48,3.57,4.67,all P ＜ 0.01).With the increase of uric acid,the levels of shrink blood pressure andthe diastolic blood pressure had an increasing trend(P ＜ 0.01).In prehypertension group,the uric acid level of men was (363.16 ± 32.05) μmol/L,which was significantly higher than female (311.35 ± 34.81) μmol/L (t =22.39,P ＜ 0.05).Conclusion Blood uric acid level and blood pressure level are closely related among general population,the serum uric acid increased in prehypertensive patients.The serum uric acid can provide useful prognostic information in subjects with the hypertension and the cardiovascular disease.

ObjectiveTo investigate the effect of chronic stress on hippocampal neurogenesis.MethodsChronic unpredictable mild stress(CUMS) was used as animal model to provoke a decrease of neurogenesis in hippocampus.Simultaneously,hippocampal neurogenesis was monitored by assessing cell proliferation,survival,and differentiation.All rats were divided into control group,14 d CUMS group,28 d CUMS group.ResultsThe cell proliferation in 14d CUMS group(2254.17 ± 164.41 ) or 28d CUMS( 1900.33 ± 104.10) group were decreased contrast to the control (2919.50 ± 188.80) (P＜0.01).The cell survival in 28 d CUMS group ( 1845.33± 126.88 ) were decreased contrast to the control (2404.50 ± 148.77 ) (P ＜ 0.01 ).The cell differentiation had no difference between control group and CUMS group( NeuN/BrdU(71.63 ± 10.21 ) vs (69.11 ± 11.30),GFAP/BrdU ( 14.34 ± 2.03 ) vs ( 17.27 ± 2.93 ) ) (P ＞ 0.05 ).ConclusionThese results suggest that chronic stress decreases cell proliferation and survival,but does not affect the phenotype of newborn cells in the hippocampus.

Combining the experiment teaching innovation in our college,we carried on beneficial quest to the teaching mode of the biochemistry experiment.During the practice of the designing experiment,we not only pay attention to cultivating students' creation ability,but also lay emphasis on cultivation of their autonomy ability.which is very important to improve the students,early scientific research abilities or clinical practice abilities and so on.

Rabbit blood samples were exposed to constant magnetic field within a range of intensity from 0.05 T to 0.35 T for 10 to 50 minutes, the propersities of hemorheology were measured by ektacytometry. The following results were obtained: The blood viscosity was lowed;The RBCs deformability was not changed obviously except for 10 minutes of exposure when the RBC＇s deformability was strongly decreased; The orientation index was increased; The results indicate that the magnetic field increases the RBC surface charge and results in the decrease of blood viscosity.

The characteristics and academic thoughts of Chinese Acup-Mox Medicine written by YAO Tianmin during the Republic of China was studied and analyzed in this paper. The academic thoughts of this book were confluence of Chinese and western knowledge, respecting for classics culture but not stubborn, using western science and medicine without worshiping it. The main characteristics were the scientific meridian-acupoint theory, extensive acupoint selection, "qie" method of acupuncture, high recommendation on medicated thread and ironing moxibustion, reinforcing and reducing based on the meridian direction in infantile massage, using acupuncture and cream formula for surgical treatment, and creating his own acupuncture codes.

Objective To compare the detection results and estimate the bias of two hematocyte analyzers of different brands . Methods Sysmex XE‐2100 hematocyte analyzer and Abbott CD‐1700 hematocyte analyzer were chosen to be the reference instru‐ment and comparison instrument ,respectively .40 cases of fresh whole blood samples were collected for the detection of WBC ,RBC , HGB ,HCT ,MCV ,MCH ,MCHC ,and PLT respectively by the two instruments .The correlation coefficient (r) ,regression equa‐tions and bias were calculated and compared to determine the comparability of the two instruments .Results The precisions of two hematocyte analyzers were satisfactory .When fresh whole blood was used as calibrators ,the results of all eight items of the two in‐struments had good correlations (r>0 .975) ,and the relative bias was acceptable .Conclusion The results of two hematocyte ana‐lyzers are comparable .With fresh whole blood using in the comparison test between different hematocyte analyzers ,systematic er‐rors can be discovered in time .

Objective To elucidates the effects of HPV18 E6 siRNA targeting at human papillomavirus(HPV)18 E6 gene on the proliferative activity of HeLa cells and chemotherapy sensitivity.Methods HPV18 E6 expression of HeLa cells was inhibited by siRNA interference,the change of P53 and P21 proteins expression level was measured by Western blot.MTT assay was used to detected proliferative activity and sensitivity to paclitaxel liposome of HeLa cells.Results After inhibition of E6 expression,P53 and P21 proteins increased and the growth of HeLa cells was decreased(P ＜0.01).The inhibition rate of HeLa was markedly increased after transfection of HPV18 E6 siRNA and paclitaxel liposome.Conclusion HPV18 E6 siRNA can effectively silence gene expression of E6 and inhibit proliferation of HeLa cells.HeLa cells are more sensitive to combine HPV18 E6 siRNA with paclitaxel liposome than that of control groups.

Objective To investigate familial hyperlipoproteinemia and the features of familial hyperlipoproteinemia in Lanzhou . Methods Data were from previous studies on the subject .Families of hyperlipoproteinemia were screening ,questionnaires were col-lected ,physical examination and laboratory data of family members were also colleted to analysis the characteristics of familial hy-perlipoproteinemia .Results A total of 39 familial hyperlipoproteinemia families were enrolled in the study ,including 280 family members .There were 15 core families ,11 single-parent families ,and 13 orphaned families .There were 6 familial hypercholesterol-emia families ,9 familial hypertriglycerides families ,24 mixed familial hyperlipidemia families .The children of the first generation ac-counted for 63 .2% of the total number of people enrolled in the study ,the father generation accounted for 14 .3% ,the children of the second geration accounted for 22 .5% .Conclusion In the survey ,the most common type of familial hyperlipidemia was mixed familial hyperlipidemia .The father generation was majority .The member of core families was less than incomplete families .

On the basis of systematicly reviewing the developmental history of acupuncture and moxibustion and profoundly understanding its academic connotations,the authors of the present article make a summary and analysis on the key factors influencing the development of acupuncturology. These key factors are 1) the emergence of "microacupuncture needle regulating-Qi" and the establishement of their corresponding theory system,2) a large number of practitioners who inherited the learnings of acupuncturology generations by generations,and abundant medical classical works which recorded the valuable academic thoughts and clinical experience of the predecesors,3) the application of acupuncture charts and manikins,and 4) modernizing changes of acupuncture learnings after introduction of western medicine to China. Just under the influence of these key factors,the acupuncture medicine separates itself from the level of the simple experience medicine,and has formed a set of special theory system and developed into a mature subject.
