Four key attributes,position,rate,shape and force,are programs of pulse tracing put forward by ZHOU Xue-hai,a medical practitioner in late Qing dynasty.The essences of four key attributes are'images'of di erent levels.There are complex relationships between pulse tracing and position,rate,shape and force attributes,which include not only subordinate relationship and static-dynamic relationship between four attributes but double relationship between four attributes and pulse tracing.

P-glycoprotein (P-gp) belongs to the member of the super-family of ATP-binding cassette (ABC) transporters. It is the 170KD glycoprotein which is the product of the MDR1 gene, located in chromosome 7q21. It is an ATP-dependent exported and oriented transporter and involved in various physiological functions as well as the transport process of many types of drugs in the body. The physiological function of P-gp is to pump the toxic metabolites out of the cell in order to reduce the accumulation of toxic products so as to protect the cells from the poison. However, in pathological condition, the drug which used to treat the disease may be pumped out of the cells by the P-gp. Therefore,the P-gp is the main cause of the multidrug resistance in clinical disease such as tumor and some neurologic diseases. The cross-resistance phenomenon is leading to poor efficacy for these diseases treatment.Panax notoginseng as the characteristic Chinese herbal medicine in Yunnan province, it has many significant effects in the treatment and prevention of many diseases such as cerebrovascular diseases. It can improve the blood hemorrheology,prevent the produce of the peroxy radical, alleviate intracellular calcium overload,treat inflammation,as well as improve the immune system function. Meanwhile, some research recently reported that it also has a considerable prospect with its multi-target and multi-channel regulation in the reversal of the MDR1 and the P-gp genes expression. This paper reviews the progress of the down-regulated expression of P-gp and MDR1 genes through different pathways, and the mechanism of Panax notoginseng and its monomer compositions on down-regulated the expression of the P-gp and MDR1 genes.

Objective To compare the curative effects between radiofrequency coblation and CO2 Laser in treat-ment of vocal leukoplakia. Methods Clinical data of 29 patients with vocal leukoplakia were retrospectively ana-lyzed. 14 of them were using radiofrequency ablation, the other 15 were using CO2 laser as treatment. Then compare the postoperative pain, postoperative wound healing, the first operation control rate of local recurrence between the two groups. Results Postoperative pain between the two groups has no statistically significance. The mucosal recov-ery of radiofrequency group in 1 month after surgery was better than CO2 laser group. In radiofrequency group, 5 cases suffered recurrence, the recurrence rate was 35.71%; In CO2 laser group, only 1 case suffered recurrence, the recurrence rate was 6.67%. Conclusions Laser and radiofrequency ablation were minimally invasive treatment for vocal cord leukoplakia, while CO2 laser as treatment has lower recurrence rate.

Objective To evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on unilateral spatial neglect in stroke patients. Methods Published articles from the earliest date available to July, 2016 were recalled from PubMed, OVID, Embase, Co-chrane Library, CNKI, VIP and Wanfang Database. Two reviewers selected independently the randomized controlled trials (RCTs) about rT-MS for stroke patients with unilateral spatial neglect, and extracted data independently and analyzed with RevMan 5.3 and GRADE profiler 3.6. Results Twelve trials that represented 353 participants were evaluated. For improving Line Bisection Test, Star Cancellation Test, Albert Test, rTMS groups were significantly more effective than the controls. rTMS groups with different frequencies all showed significantly effec-tive:for low frequency rTMS, SMD=-1.21, 95%CI=-2.17 to-0.25;for high frequency rTMS, SMD=-2.56, 95%CI=-3.54 to-1.58;for continuous theta burst stimulation (cTBS), SMD=-2.51, 95%CI=-3.66 to-1.36. Conclusion rTMS is effective on unilateral spatial neglec-tin in stroke patients.

Objective To assess the changes of left ventricule and analyze the influential factors in pulmonary hypertension (PH) by comparing the changes of left ventricular volume and function using single cardiac cycle real-time three dimensional echocardiography ( sRT-3DE ) and two-dimensional echocardiography (2DE).Methods In case group,there were 30 inpatients diagnosed as PH,systolic pulmonary artery pressure(PASP)≥40 mmHg estimated by echocardiography,excluding left heart disease or congenital systemic-pulmonary circulation shunt.There were 30 healthy people as control group.Conventional 2DE and sRT-3DE were performed in both groups and obtained 2D and 3D parameters.Results ①In case group,the 2D-LVEF were significantly larger than 3D-LVEF (P ＜ 0.01 ).There was less agreement of 2DE and 3DE in case group than in control.②Comparing with the control group,left ventricular EDV,ESV and SV in ease group decreased ( P ＜0.01 ),so as to 3D-LVEF ( P ＜0.05).The left ventricular spherical index(SIs,SId)and eccentric index (EId,EIs ) in case group were significantly larger than those in control group ( P ＜0.01 ).③LVEDV in case group was negatively correlated with PASP (r =- 0.47),and positively correlated with RVSV and RVEF ( r =0.84,0.66) ;3D-LVEF in case group was negatively correlated with PASP ( r =- 0.54),and positively correlated with RVSV and RVEF ( r =0.58,0.53); there was no significant correlation between LVEDV and RVEDV.LVEDV was negatively correlated with SIs and SId ( r =-0.65,-0.61),so as to EId and EIs ( r =-0.67,0.67).LVEF was negatively correlated with SIs and SId ( r =-0.64,-0.61),so as to EId and EIs ( r =-0.66,-0.68),and the corresponding P all above were less than 0.01.Conclusions PH can result in reductions of left ventricular volume and systolic function,and the variations of which have the correlations with the severity of PH and the increase in SI and EI.sRT-3DE can provide a method to get more accurate information of left ventricle.

Purpose To investigate the value of systemic abdominal ultrasonography in the diagnosis of acute abdominal diseases. Materials and Methods A total of 234 patients with acute abdominal diseases were enrolled consecutively in the study and randomly divided into the study group who received systemic abdominal ultrasonography and the control group who received traditional selective abdominal ultrasonography. The diagnose accordance rate and diagnose duration of two groups were compared with the results of pathology or clinical follow-up which served as the golden standard. Results The diagnose accordance rate in the study group (95.04%, 115/121) was significantly higher than that of the control group (86.73%, 98/113) (χ2=4.946, P<0.05);the ultrasound examination duration in the study group was statistically longer than that of the control group [(16.41±1.31) min vs (10.11±4.35) min, t=14.771, P<0.05], and the diagnose duration in the study group was significantly shorter than that of the control group [(2.00±1.30) h vs (2.65±1.72) h, t=3.301, P<0.05]. Conclusion Systemic abdominal ultrasonography can improve the diagnosis coincidence rate and shorten the duration in the diagnosis of acute abdominal diseases.
