ABSTRACT
Tongsaimai Tablets/Capsules are composed of Lonicerae Japonicae Flos, Angelicae Sinensis Radix, Achyranthis Bidentatae Radix, Codonopsis Radix, Dendrobii Caulis, Astragali Radix, Scrophulariae Radix, and Glycyrrhizae Radix et Rhizoma, and are effective in promoting blood circulation, removing blood stasis, supplementing Qi, and nourishing Yin. It is widely used in the treatment of peripheral vascular diseases. With 40 years of clinical application, it has accumulated substantial research data and application experience. Its good clinical efficacy and pharmacoeconomic benefits in improving the clinical symptoms of peripheral vascular diseases have been confirmed by relevant research. Meanwhile, this drug has also been recommended by many expert consensus, guidelines, and teaching materials, serving as one of the most commonly used Chinese patent medicines in clinical practice. To further improve the understanding of the drug among clinicians and properly guide its clinical medication, the China Association of Chinese Medicine took the lead and organized experts to jointly formulate this expert consensus. Based on the questionnaire survey of clinicians and the systematic review of research literature on Tongsaimai Tablets/Capsules with clinical problems in the PICO framework, the consensus, combined with expert experience, concludes recommendations or consensus suggestions by GRADE system with the optimal evidence available through the nominal group technique. This consensus defines the indications, usage, dosage, course of treatment, medication time, combined medication, and precautions of Tongsaimai Tablets/Capsules in the treatment of peripheral vascular diseases, and explains the safety of its clinical application. It is recommended for clinicians and pharmacists in the peripheral vascular department(vascular surgery), traditional Chinese medicine surgery(general surgery), and endocrinology department of hospitals at all levels in China.

AIM: To compare the efficiency and safety of torsional phacoemulsification with or without intelligent phacoemulsification ( IP ) software in hard nucleus cataract extraction. METHODS: Ninety two eyes with Ⅳ - Ⅴ grades cataracts were enrolled in this randomized prospective study. Operated eyes were divided into two groups -those operated without IP software ( non- IP group, n =43) and those operated using IP software (IP group, n =49 ). The two groups were compared in terms of ultrasound time (UST) and cumulative dissipated energy (CDE). Post- operative outcome measures included the corneal edema and best-corrected visual acuity (BCVA) at 1,7d and 3mo postoperatively, corneal endothelial cell density and percentage of hexagonal cell at 7d and 3mo postoperatively. RESULTS: UST was measured as 52. 51±9. 64s in non-IP Group and 48. 79±7. 13s in IP Group (P = 0. 030). CDE was 15. 78±3. 73% in non-IP Group and 14. 29±2. 77% in IP Group ( P = 0. 026). At the first postoperative day, the rate of BCVA>0. 1 in non-IP Group was 56%, and the rate in IP Group was 79% (P= 0. 066). Corneal edema in non-IP Group was 2. 98±0. 77 scores, and in IP Group it was 2. 61±0. 64 scores (P = 0. 021). At the postoperative 7 and 30d, the BCVA and corneal edema were no differences between two groups. At the postoperative 7d, corneal endothelial cell density in non- IP Group were 2497. 95 ±211. 48 / mm2 , less than 2586. 26±154. 71 / mm 2 in IP Group (P= 0. 029);percentage of hexagonal cell in IP group was 48. 33±8. 69%,higher than 44. 19±9. 48% of non-IP group(P= 0. 030).CONCLUSION: In hard nucleus cataract extraction, the IP software can combine the advantages of the two kinds of ultrasonic modes, which is more effective with lower ultrasound energy and less injury for the corneal endothclium, and is helpful for the recovery of vision at early stage after surgeries.
ABSTRACT
<p><b>OBJECTIVE</b>To discuss the trend of displacement on the side of nondistraction when distraction osteogenesis with unilateral incomplete osteotomy of canine mandible.</p><p><b>METHODS</b>The method of finite element analysis was used to simulate distraction osteogenesis with unilateral incomplete osteotomy and the displacement of six marked point such as the temporomandibular joint and the angle of mandible and coracoid process and teeth were observed on nondistractional side when the transport disc was distracted with a distance and without a distance.</p><p><b>RESULTS</b>When the transport disc was distracted without a distance, the Von Mises stress was 0 in the six marked point of nondisractional side and their displacement in 3 dimensions (X, Y, Z axis) was 0. When the transport disc was distracted with 1 mm width, all marked point had some displacement.</p><p><b>CONCLUSION</b>When distracted and observed from the side of distraction, the mandible at the side of nondistraction has the trend of contrarotation round the center of the transverse ridge mid-point of condyle process on the plane of sagittal, whereas it has the trend of parallel movement approximately in the direction of opposite side on the plane of coronary.</p>

<p><b>OBJECTIVE</b>To analyze the characteristics of idiopathic pulmonary arterial hypertension (IPAH) and predict the prognosis of IPAH by Echocardiogram and Right Heart Catheterization.</p><p><b>METHODS</b>108 IPAH patients who was diagnosed as IPAH in Fuwai hospital from Jan 2003 to Jun 2007 were retrospectively analyzed and followed up to June 2008, the statistical analysis software was SPSS 13.0.</p><p><b>RESULT</b>The mean age of the 108 IPAH patients was (32.5 +/- 12.6) years, the ratio of female and male was 2.86:1, the average time from appearing symptom to diagnosis was (34.9 +/- 36.3) months, the incidence of syncope, hepatomegaly, hemoptysis and Edema of lower extremity was 32.4%, 27.8%, 15.7% and 14.8% respectively. A total of 94 patients (87.0%) were followed up for (27.6 +/- 14.7) months, forty-two patients (38.9%) died of right heart failure, the mean death time was (11.6 +/- 9.4) months after diagnosis, the survival rate of 1, 2 and 3 years was 74%, 58% and 44% respectively. These following variables could predict survival in univariate analysis: Systolic Blood Pressure (SBP) (P < 0.01, RR = 0.937), pulse Pressure (PP) (P < 0.01, RR = 0.930), left ventricular End-Diastolic Dimension (LVEDD) (P = 0.004, RR = 0.924), right ventricular End-Diastolic Dimension (RVEDD) (P = 0.029, RR = 1.045), RVEDD/LVEDD (P = 0.003, RR = 3.222), Pulmonary Arterial Systolic Pressure (PASP) measured by echocardiogram (P = 0.002, RR = 1.022), PASP (P = 0.030, RR = 1.026), mean Pulmonary Arterial Pressure (mPAP) (P = 0.031, RR = 1.037) and Pulmonary Vascular Resistance (PVR) measured by right heart catheter (P = 0.019, RR = 1.001). in multivariate analysis, PP (P < 0.01, RR = 0.923), RVEDD/LVEDD (P = 0.006, RR = 3.126) and PASP measured by Echocardiogram (P = 0.002, RR = 1.022), PASP, mPAP, PVR measured by right heart catheter (P = 0.017, RR = 1.001) were predictive.</p><p><b>CONCLUSION</b>IPAH was prone to attack young women with a poor prognosis, the diagnosis of IPAH at an early stage was difficult because of nonspecific symptom, syncope, hepatomegaly and Edema of lower extremity can predict the severity of IPAH, PVR measured by right heart catheterization, PP and PASP were independently predictive factors for IPAH.</p>
