Objective For the purpose of exploring the influence exerued by the amount of template DNA on the results of automatic fluerescent detection. Method For the purpose of buiding the optimal amount of template DNA amplified, we have analyzed different amount of template DNA (9947A) by 3100 Genetic Analyzer with the multiplexing Profiler Plus Kit. Results The optimal amounts of template DNA amplified were between 0.31ng and 2. 5ng by using 3100 Genetic Analyzer. Conclusion It will produce the incorrect analytic results if the amounts of template DNA were too high or too low.

Objective To observe the clinical curative effect of Xiaoer Chiqiao Qingre granule in the treatment of infantile upper respiratory tract infections.Methods 100 children with upper respiratory tract infection were selected,and they were randomly divided into observation group and control group,50 cases in each group.The observation group was treated with Xiaoer Chiqiao Qingre granule,the control group was given ribavirin effervescent granules.The effects of the two groups were observed.Results The total effective rate of the observation group was 96％,which was significantly higher than 78％ of the control group (x2 =9.500 6,P ＜ 0.05).The fever,symptoms and signs of improvement time in the observation group were better than those in the control group.Conclusion Xiaoer Chiqiao Qingre granule in the treatment of infantile upper respiratory tract infection can defervesce quickly,and has quick curative effect,so it is worthy of promotion.

Objective To explore the therapy measurement of iron deficiency anemia(IDA)associated helicobacter pylori(HP)infection among children.Methods Eight hundred and ninty nine cases entrusted children aged from 2 to 7 years old were measured hemoglobin(Hb),mean corpuscular volume(MCV)mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and serum ferri,serum fettin(SF),HP-IgG antibodies.Divided the HP-IgG positive cases into two groups for treatment,The treatment group adopted omeprazole,amoxicillin and metronidazole to cure them for two weeks,then oral ferrous sulfate sugar liquid.The contrast group purely take the ferrous sulfate sugar liquid.After eight weeks re-examined the Hb and SF.Results Totally 279 cases were diagnosed as Hp-positive,620 as HP-negative and 99 children diagnosed as IDA,among the 99 cases IDA,58 cases with HP infection(20.8%) and 41 cases with non-HP infection(6.7%).That means the number of IDA cases with HP infection was higher than those with non-HP infection(?2=39.46 P

Objective:To study the protective effect of Ginkgo biloba L.extract(EGB) on PC12 cell damage induced by rotenone and 1-methyl-4-phenylpyridium(MPP +). Methods: PC12 cells damage model was induced with different concentrations of rotenone and MPP + and were treated with EGB . Then cell morphology was observed; survival rate and ultracellular dopamine (DA) level were determined by MTT assay and ELISA assay, respectively. Results: MPP + -induced damage was attenuated by pre- or co-treatment with EGB at 0.35,0.70 and 1.40 mg/ml, while rotenone-induced damage was attenuated with EGB only at 1.40 mg/ml.The DA concentrations of extracellular at 2 mmol/L MPP + (6.875?0.201) ng/ml and 10 ?mol/L rotenone (5.321?0.167) ng/ml increased to ( 7.595?0.139 ) ng/ml (P

Objective To explore the effect of androgen on learning and memory ability and neurons in hippocampal CA1 region in senescence accelerated mouse prone strain/8(SAMP8).Methods Thirty 7-month-old male SAMP8 were randomly divided into sham-operation control group,castrated group and androgen replacement therapy after castration group.The dose of testosterone undecanoate(TU) was 37.4mg/(kg?15d).The capability of learning and memory was observed 45 days later through the Morris water maze(MWM) test and the change of neurons in hippocampal CA1 region was detected and analyzed by HE staining,immunohistochemal method and computer pathological image analysis system.Results 1.In the MWM test,the escape latency of castrated group were significantly prolonged(P0.05).2.With HE staining,neurons in hippocampal CA1 region of castrated group were found with diffused vacuolar degeneration,and sparse and disordered cellular arranpement.The cell nucleuses were karyochrome and karyopycnosis.The number and optical density of A? immune positive neurons were markedly higher than those of other groups(P

Objective To systematically evaluate the efficacy and safety of telmisartan and amlodipine in treatment of hypertension complicated with diabetes.Methods Retrieved from PubMed, EMBASE, Cochrane library, CNKI, VIP and Wanfang database by computer, randomized controlled trials( RCTs) about telmisartan versus amlodipine in treatment of hypertension and diabetes were collected, then relevant date were extracted, Meta-analysis was drawn by RevMan 5.3 statistical software.Results A total of 11 RCTs were included involving 914 patients.The results of Meta-analysis revealed that telmisartan was better than amlodipine in fasting blood glucose reduction[MD =-0.54,95%CI( -0.87, -0.21),P =0.001], glycosylated hemoglobinreduction[MD=-0.60,95%CI( -1.12,-0.07),P =0.03] and HOMA insulin resistance index reduction[MD =-1.27, 95%CI( -1.81,-0.73),P<0.001],there were statistical significance.There were no significant difference in systolic blood pressure[MD =2.39, 95%CI( -0.21,4.98),P=0.07],diastolic blood pressure[MD =0.17,95%CI( -0.95,1.29),P =0.77] and adverse drug reaction[RR=0.70, 95%CI(0.41,1.19),P=0.19].Conclusion For patients with hypertension and diabetes, telmisartan in decreasing fasting blood glucose, glycosylated hemoglobinand HOMA insulin resistance index is more effective than that of amlodipine, blood pressure in patients with equivalent,antihypertensive and safety are similar.

Objective To analyze the differences in the clinical characteristics,endoscopy,pathology and therapy between the patients with new onset ulcerative colitis(UC) in the elderly versus youth and middle-aged patients.Methods A review analysis was carried out in the 178 hospitalized patients with UC in Third Hospital of Peking University from 1994 to 2010.The patients were divided into two groups according to the age of onset:UC onset at age of 60 years and older were enrolled in elderly group; UC onset at age less than sixty years were enrolled in youth and middle-aged group.The data of clinical manifestation,endoscopy,pathology,laboratory test,the severity of disease classification and therapy were analyzed and compared between the two groups.Results The elderly group consisted of 21 men and 6 women.The youth and middle-aged group consisted of 83 men and 68 women.The ratio of male was higher in elderly group than in youth and middle-aged group (77.8％ vs.55.0％,P＜0.05).No significant difference in the clinical type of UC was observed (P＞0.05).The ratio of abdominal pain in elderly group was lower than in youth and middle-aged group (44.4％ vs.78.8％,P＜0.05).There were no significant differences in other symptoms,laboratory test and the severity of disease between the two groups (all P＞0.05).The ratio of Grade Ⅰ and Ⅱwas much higher in the elderly than in youth-middle-aged group(70.4％ vs.39.9％,P＜0.05),but the ratio of Grade Ⅲ and Ⅳ was much lower in the elderly than in youth-middle group(29.6％ vs.60.1％,P＜0.05).No significant differences between the two groups were found in the extent of disease,pathological characteristics and therapy (all P＞0.05).Conclusions Compared with the youth and middle-aged patients with onset UC,the ratio of male patients was higher,the ratio of abdominal pain was lower,and the severity of endoscopic manifestation was less in the elderly patients with onset UC.
