OBJECTIVETo explore the mechanisms involved in the ligustrazine alleviation of the pulmonary artery hypertension (PAH) in patients of chronic obstructive pulmonary disease (COPD) associated with chronic cor pulmonale (CCP) during exacerbation.
METHODSSeventy patients of COPD and CCP with acute exacerbation were randomly and equally divided into control group and treatment group. The control group received standard treatment with antibiotics, antiasthmatic and expectorant medications, and oxygenation; and the ligustrazine treatment group received ligustrazine treatment (80 mg/d; i.v.; for 2 weeks) in addition to the standard treatment. Before and at the end of 2 week treatment, the clinic responses of the two regimens were evaluated, plasma levels of endothelin-1 (ET-1) and nitric oxide (NO) were determined; arterial oxygen partial pressure (PaO2, mean pulmonary arterial pressure (mPAP), outflow tract of right ventricle (RVOT), and internal diameter of right ventricle (RV) were measured.
RESULTSGood clinic benefits were achieved in both the standard and ligustrazine regimens, plasma level of ET-1, values of mPAP, RV and RVOT decreased significantly, plasma level of NO and PaO2 values decreased (all P < 0.01 vs pre-treatment to all parameters). Compared with the control group, ligustrazine greatly enhanced the clinic efficacy from 77.1% to 97.1% (P < 0.05), and also resulted in more significant changes of all these parameters (P < 0.01 vs control group for all parameters). For both groups, the levels of plasma ET-1 were positively correlated with values of mPAP, RVOT, and RV (r = 0.710, 0.853, and 0.766, respectively, all P = 0.000), and negatively correlated with plasma NO and PaO2 (r = - 0.823, and - 0.752, respectively, all P = 0.000).
CONCLUSIONLigustrazine is effective in treating pulmonary artery hypertension during acute exacerbation of COPD and CCP in patients from the plateau area. The observed changes in the plasma levels of NO and ET-1 in response to ligustrazine treatment suggest that ligustrazine may act through the selective effect on pulmonary blood vessels to enhance the synthesis and release of NO and suppress those of ET-1 from lung vascular endothelial cells, thus reducing pulmonary artery pressure and decreasing pulmonary arterial hypertension.

Background:The prevalence rate of diabetes mellitus ( DM ) associated with gastroesophageal reflux disease ( GERD)is increasing recently,and the relationship between DM and GERD has become a research hotspot. Aims:To study clinical features and influential factors of therapeutic efficacy of reflux esophagitis( RE)in elderly patients with type 2 DM(T2DM). Methods:Two hundred elderly patients with RE diagnosed by gastroscopy from March 2011 to October 2013 were enrolled,and divided into T2DM associated with RE( T2DM)group and RE group. The clinical features, endoscopic findings and therapeutic efficacy of the two groups were analyzed,and the influences of DM course and control of blood glucose on efficacy of RE were also analyzed. Results:The main manifestations of RE were extraesophageal symptoms,typical esophageal symptoms were less common. The overall efficacy rate decreased with the increase of endoscopic grade of RE,however,extraesophageal symptoms improved significantly. With the prolonging of DM course,the endoscopic grade of RE was increased,and the control of blood glucose was worse. The overall therapeutic efficacy was significantly reduced with the prolonging of DM course in patients with well controlled blood glucose. Conclusions:Extraesophageal symptoms are common,endoscopic grade of RE is worse and blood glucose is difficult to control in elderly T2DM patients associated with RE. DM course and status of blood glucose control have influences on the therapeutic efficacy of RE.

BACKGROUND:Knee joint is the most complicated structure of human body, and X-ray is often used to reflect the stenosis of knee compartment. However, radiographs are two-dimensional projection of three-dimensional joint structure. Thus, different joint shooting locations can impact the outcomes of measurement, and it is difficult to ensure the accuracy of repeated measurements. OBJECTIVE:To build three-dimensional model of knee compartment, measure the distance and volume, and provide the basis for subsequent models, biomechanics and relevant clinical studies. METHODS:Based on the principle of reverse engineering, using CT images of the knee joint and the software of Mimics, three-dimensional model of medial compartment knee structure was reconstructed. After the model was imported and smoothed, the medial and lateral compartment volumes were finaly calculated by the software of Geomagic Studio. RESULTS AND CONCLUSION: Three-dimensional model of the knee compartment, including femur, tibia and fibula, was successfuly structured by CT images. The models of knee and knee compartment could be observed at any angle or observed individualy, and could be measured. It was discovered that the volume of medial and lateral compartments of knee is close, although the joint space width of them is different, which ilustrates that the procedure can accurately reflect the degree of knee joint space width in the round by calculating the volume of medial and lateral compartments of knee joint through computer.
