Objective To evaluate the arc renal parenchyma incision of pelvis within renal sinus and renal posterior lib for the removal of complex staghorn renal calculi.Methods Arc renal parenchyma incision of pelvis within renal sinus and renal posterior lib was performed to remove stones in 86 cases (97 sides) with complex staghorn renal calculi.Among the 86 cases,42 had stones on the right side;33,on the left side;11,on bilateral sides.Seventeen cases had concomitantly calculi in the ureter,and 54 had calculi in upper and mid calyx or multiple renal calculi.As for comorbidity,11 cases had hypertensions;4,diabetes; and 5,hepatitis B.Twenty-five cases had renal insufficiency,with BUN of 12.3 -76.0mmol/L and Cr of 231 -1721?mol/L.The procedure was performed as follows:the kidney was dissected free and the pelvis within renal sinus was isolated.Two rows of bottom style sutures were made on the renal parenchyma with 2-0 plain catgut along mid-lower 1/3 of the dorsal surface of kidney free of vessels from the renal posterior lib to the plane of lower major calyx.The renal parenchyma was opened.Then,the incision was developed from the plane of lower through the middle major calyx to the plane of upper major calyx.The renal parenchyma and mid-low calyx along the incision were opened,suturing while incising,so that all the stones could be easily removed with hook.Results The calculi were completely removed in all 86 cases (97 sides).The opera- tive time was 105-187min ( mean,129min).The intraoperative blood loss was 120-460 ml ( mean,220 ml).Forty-three cases needed intraoperative blood transfusion of 120 -200 ml (mean,140 ml).One month after operation,KUB+IVU and ultrasonic findings were normal with improved hydronephrosis,no intrarenal stricture and no residual calculi.Conclusions This procedure has the advantages of less bleeding,slight impairment of renal function,simple handling,clear operative field,high clearance rate,therefore is indica- ted for the removal of complex staghorn calculi.

Objective To compare the effectiveness and safety of different intracranial stents assisted coil embolization of intracranial aneurysms and to discuss the selection of different stent assisted embolization of intracranial aneurysm.Methods From 2007 April to 2012 April,118 cases (a total of 128 wide-neck aneurysms) with intracranial aneurysms were analyzed retrospectively.This included the use of 70 neuroform,38 Enterprise,and 20 Solitaire AB stents forthe treatment of intracranial aneurysms.The successful use,aneurysm occlusion at the immediate post-operation,and early period of peri-operative complications were recorded from those clinical data in order to assess the effectiveness and safety of the different intracranial stents,which assisted coil embolization of intracranial aneurysms.Rank sum test and x2 test were used for statistics.Results Three aneurysms assisted with Neuroform stent were planted unsuccessfully,and the Enterprise and Solitaire stents were placed successfully.The embolism results of three stents after immediate postoperative angiography aneurysm: Neuroform stent occlusion rate was 40.0％ (28/ 70),the tumor residual rate was 38.6 ％ (27/70),and the partial embolization rate was 21.4 ％ (15/70) ; The Enterprise stent occlusion rate was 42.1％ (16/38),the tumor residual rate was 36.8 ％ (14/38),and the partial embolization rate was 21.1％ (8/38).The Solitaire AB stent occlusion rate was 40.0 ％ (8/20),the tumor residual rate was 35.0 ％ (7/20),and the partial embolization rate was 25.0 ％ (5/20).There were not significant differences in aneurismal occlusion (H =0.12,P ＞ 0.05).Early peri-operative complications results were: Neuroform stent occurred in 7,Enterprise frame in 4,and Solitaire AB stent occurred in 2.There were no significant differences in the incidence of complications in the early period after coiling (x2 =0,P ＞ 0.05).Conclusions Three kinds of intracranial stents assisted embolization of intracranial aneurysms are applied safely and effectively.The stent may be chosen according to morphology of parent artery and stent biological character.

Objective To probe into clinical value of real-time three-dimensional echocardiography (RT-3DE) in evaluating global and regional left ventricular function in patients with acute inferior, posterior and lateral myocardial infarction(MI).Methods The study consisted of 41 normal subjects and 23 patients with acute MI.RT-3DE was performed and three-dimensional image data was analyzed offline with software.A series of global and regional left ventricular volume curves were plotted.Regional and global diastolic volumes, regional and global systolic volumes, regional and global ejection fractions, regional stroke volume to global diastolic volume were compared respectively between control group and MI group.Results By contrast with control group, global left ventricle function and regional left ventricle function in the zones with infarction and part of the zones close to infarction had significant difference( P＜0.05),however,no effective statistic change was found in the most of the distal zones of infarction( P＞0.05).Conclusions RT-3DE can accurately evaluate measurement the left ventricular global and regional function in patients with acute MI.

In order to make sure whether Panax notoginseng is sensitive to chloridion and guide fertilization in planting of P. notoginseng, the effects of the different proportion of potassium chloride (KCl) and potassium sulfate (K2SO4) on the yield, quality of P. notoginseng were studied. The results showed that K fertilizer significantly improved the growth of P. notoginseng and increased the biomass per plant or per pot and the content of N, P, K and the content of saponin. In cases of conditions such as potassium, and the effects of K2SO4 on increasing the petiole length, leaf size, rhizome length, root length, and content and accumulation of Ginsenoside Rg1 were better than those of KCl. While compared with K2SO4, KCl was more conducive to augmenting height, root width, the biomass of shoot, rhizome, root and the content of Ginsenoside Rb1 and Rd. There was not remarkable difference in agronomic characters, biomass and the content of N, P, K among KCl, K2SO4 and the combination of KCl and K2SO4. However, the content of saponin of the treatment with combination of KCl and K2SO4 was significant higher than that of single KCl or K2SO4 treatments. K fertilizer significantly increased yield and the content of saponins. And P. notoginseng was not sensitive to chloridion. KCl increased the yield and the content of saponins of P. notoginseng as well as K2SO4, and the combination treatment was superior to single treatment. It is recommended that the KCl should be adopted in production, to reduce the cost of potash fertilizer.

OBJECTIVETo compare the effect of reinforcing Shen method (RSM) and activating blood method (ABM) in treating osteoarthritis (OA) at the molecular level.

METHODSThe physical and chemical characteristics of components from respective recipes of RSM and ABM, and network features of component-target interaction network were analyzed by computer simulation methods including chemical space, molecular docking, and biological network, etc.

RESULTSThe chemical components of RSM and ABM were scarcely scattered with larger overlapping. Among established networks, the distribution of network features was partially similar in RSM and ABM. The average target number correlated with each component was 1.86 in RSM and 2.11 in ABM respectively. Each average target number was respectively correlated with 4.46 compounds and 3.93 compounds, reflecting multi-component and multi-target actions.

CONCLUSIONComputer simulation could intuitively trace out similarities and differences of two different methods and their interaction with targets, which revealed that the compatibility of RSM and ABM could have broader protein targets and potential synergism at the molecular level.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.
