The effects and methods of acupuncture on promoting blood circulation and removing stasis and its importance for modern clinical acupuncture are explored and explained. The acupuncture theory of promoting blood circulation and removing stasis in Internal Canon of Yellow Emperor and the ancient medical scholars' knowledge of acupuncture for promoting blood circulation and removing stasis are traced, and then the principles and characteristics of acupuncture for promoting blood circulation and removing stasis are explored and summarized. The methods and common tools of prompting blood circulation and removing stasis of modern clinical acupuncture are summed up as well. It is considered that the treatment principles and methods of acupuncture for prompting blood and removing stasis deserve to be paid attention to and applied by all departments of clinical acupuncture.

Objective To explore the diagnosis value of CRP combined with BNP detection in elderly patients with myocardial infarction heart failure.Methods 360 patients with myocardial infarction were selected as subjects.And they were divided into non -heart failure group(n =187)and heart failure group(n =173).The heart failure group was divided into three groups according to the NHYA heart function.To observe and compare the contents of BNP and CRP of patients in different groups.Results CRP in the non -heart failure group was (6.24 ± 3.01)mg/L,which was significantly lower than (16.77 ±2.67)mg/L in the heart failure group (t =1 754.892,P <0.05 ).BNP in the non -heart failure group was (521.91 ±29.11 )pg/L,which was significantly lower than (2 995.39 ±496.48)pg/L in the heart failure group (t =1 754.892,P <0.05).And the contents of BNP and CRP in high NHYA patients were more higher than those in low NHYA patients.The positive rate of CRP combined with BNP detection was 93.64%,which was higher than 69.44% in single CRP detection (χ2 =32.622,P <0.05),and 79.44% in the single BNP detection (χ2 =14.442,P <0.05).Conclusion The plasma BNP and CRP can help diagnose heart failure with old myocardial infarction and heart failure degree classification.

There are four type of Potter typing of cystic kidney disease in children:autosomal recessive polycystic kidney disease,multicystic dysplastic kidney,autosomal dominant polycystic kidney disease and obstructive cystic dysplastic kidney.However,simple cyst of kidney multilocular cystic renal tumors and other genetic syndrome also can make kidney cystic change.Due to the different pathogenesis and pathological basisn,the clinical diagnosis and treatment is also different.The correct diagnosis of these diseases requires chinical classification and determination of the causes of the diseases.This paper will make a review on the common cystic kidney disease in children.

Objective: To elucidate the relationship between Notch3 expression and chemosensitivity of human colon carcinoma cell line SW620 to topotecan. Methods: Notch3 siRNA was transfected into SW620 cells, and the expression of Notch3 in SW620 cells was examined by Western blotting. After transfected with Notch3 siRNA for different time peri-ods, SW620 cells were further treated with topotecan, and the proliferation of SW620 cells was detected by MTT assay; the apoptosis of SW620 cells was detected by Hoechst 33342 staining and flow cytometry. Caspase-3 activation in SW620 cells was examined by caspase-3 activation kit. Results: Notch3 siRNA transfection remarkably inhibited Notch3 protein expression in SW620 cells. The IC_(50) of topotecan in Notch3 siRNA-transfected group was significantly decreased compared with that in the Ctrl siRNA group (P <0.05). Silence of Notch3 expression in SW620 cells by Notch3 siRNA remarkably promoted apoptosis (P < 0.05) and caspase-3 activation (P < 0.05) of SW620 cells induced by topotecan. Conclusion: Notch3 down-regulation by siRNA in SW620 cells can enhance the chemosensitivity cells to topotecan.

Objective To explore transthyretin (TTR) effect on retinal vascular endothelial cells (hREC) under high glucose and hypoxia environment.Methods hREC and human retinal pigment epithelial cell (hRPEC) were cultured at low-glucose (LG),high glucose (HG) and hypoxia.The glucose concentration was increased from 5.5 mmol/L up to 25 mmol/L,and hypoxia was induced by 200 μmol/L CoCl2.The cells were divided into LG group,LG-hypoxia group,HG group,HG-hypoxia group according to the different cell culture environment.The growth index was detected at 0,4,8,16,24,36,48,60,72 hours after cultured.Furthermore,hREC and hRPEC were also cultured with additional TTR (4 μmol/L),respectively.Then transwell co-culture system was employed to reveal the effects of hRPEC on the growth of hREC.Results At 72 hours after cultured,the growth index of hREC and hRPEC in LG group were increased as compared with LG-hypoxia group and HG group (hREC:F=17.098,22.970;P＜0.05.hRPEC:F=45.442,9.011;P＜0.05);the growth index of hREC and hRPEC were decreased in HG group and HG-hypoxia group (hREC:F=146.184,P＜0.05;hRPEC:F=27.907,P＜0.05).Additionally,hREC could be significantly repressed by added TTR during culture with high concentration of glucose (F=161.430,24.106;P＜0.05).hREC could be significantly increased by added TTR during culture with low concentration of glucose (F =200.486,48.662;P ＜ 0.05).In co-culture process,hRPEC revealed inhibition activity against hREC under both natural and abnormal environment (LG group:F=15.711,P＜ 0.05;LG-hypoxia group:F =45.659,P＜0.05;HG group:F =7.857,P ＜0.05;HG-hypoxia group:F=6.348,P＜0.05).Conclusion Under high glucose and hypoxia environment,the growth of hREC from neovascular could be inhibited by TTR.

Schizophrenia is a common but complex mental disorder affected by multiple factors. Forensic psychiatric assessment of schizophrenia involves evaluations on many aspects, but there is no effective biological identification index for schizophrenia. Researches indicate that dysfunction of dopaminergic neurotransmission plays an important role in the pathogenesis of schizophrenia. Our study reviews the classification, genetic structure of dopamine receptors and the recent pertinent studies between the dopamine receptors and schizophrenia and its forensic significance.
