Objecttve To investigate the effects of snfentanil and ropivacaine used in labor combined spinalepidural analgesia(CSEA)and its influence on labor course and infants and its side effects.Methods 160 primiparas who chose deliver analgesia were randomly divided into two groups:group A intrathecal 5μg sufentanil plus saline up to 2.5ml,extradural 0.2μg/ml sufentanll plus 0.1% ropivacaine and saline up to 100 ml;group B extradural ropivacaine 1.5mg plus glucose 100g/L up to 2ml;group C have no analgesia.Then to investigate the effects of analgesia VAS scores,labor course duration,caesarean section rate,flooding volume,neonatal Apgar scores and its side effects.Results Compared with group C,the analgesia effects of group A and B were definitely(P＜0.05,P＜0.01);visual analogue score(VAS)at 5min,10min and 30min in group A were(3.4±1.2),(1.6 ±0.7)and(0.7 ±0.5)respectively,while in group B were(5.3±1.5),(4.3±1.8)and(3.1±1.7),which had significant difference in two groups(all P＜0.01);they all could reduce the first labor course duration,caesarean section rate,and there were no difference with group C(P＞0.05);and the flooding volume and neonatal Apgar scores had no differences(P＞0.05).Conclusion Sufentanil and ropivacaine combined used in CSEA has stronger effect and longer duration without prolonged labor coulee and poor side effects,which would be a more perfect analgesia worth clinical application in obstetrics.

Objective To analyze the data collected from surveillance sites in Shanxi province in epidemiological investigations during 2004 - 2008 and understand the influence of such factors as rat density and vectorial quantities on plague epidemic intensity, thus provide some scientific basis for plague control and prevention. Methods To collect the data of surveillance during 2004 - 2008 in the 12 counties of plague surveillance by retrospective method. Sort and analyze the collected data according to the requirement of operational scheme for plague surveillance-calculate the rat density of spermophilus dauricus, meriones meridianus and the small rodents, and the flea index and the flea infection ratio of body flea, burrow track, cave. The results of serological tests were analyzed at the same time. Results As showed in the results, the mean density of spermophilus dauricus was 1.12 merely in each hectare, and that of meriones meridianus and small rodents were 7.42%(2130/28 700) and 8.03%(3886/48 400), respectively. The flea infection rate of spermophilus dauricus and meriones meridianas were 25.78% ( 1933/7497 ) and 44.19% (2028/4598), respectively;the flea index of spermophilus dauricus and meriones meridianus were 0.59 and 1.84, respectively. The number of nests excavated with flea for spermophilus dauricus was 70, and the numbers of nests and flea were 362 and 333, respectively. The flea infection rate was 19.34 % (70/362), and the flea index was 0.92. The number of nests excavated with flea for meriones meridianus was 34, and the numbers of nests and flea were 177 and 124, respectively. The flea infection rate was 19.21%(34/177), and the flea index was 0.70. The number of caves explored for spermophilus dauricus was 7171,and the number of burrows with flea was 62, so the flea infection rate was 0.86%(62/7171 ), and the flea index was 0.01. Conclusions With a relatively high density and large quantity and considering the epidemic features of animal plague in periphery provinces in recent years, plague may still happen and spread in Shanxi province diespite the negative results of all those serological tests, by means of importing from other provinces.

Objective To study the clinical efficacy of recombinant human epidermal growth factor (rhEGF) in the treatment of sacrococcygeal decubitus ulcers grade Ⅲ with direct polymerizing suture after appling rhEGF to reinforce wound bed preparation (WBP). Methods From January 2007 to October 2009, 60 patients with sacrococcygeal decubitus ulcers Grade Ⅲ, were divided into control group and treatment group. The ulcer size was 3 cm × 4 cm to 10 cm × 12 cm and all ulcers were infected for 15-70 d. Treatment group received traditional dressing change and appling rhEGF to reinforce wound bed preparation. Control group received traditional dressing change only. The operative technique that we used in two groups was direct polymerizing suture. Cure rate of stage Ⅰ and complication morbidities were analyzed. Results Cure rate of stage Ⅰ was 87% in treatment group and 70% in control group. Complication morbidities were 13% in treatment group and 30% in control group. The difference between these two groups was statistically significant (P ＜ 0.05). Conclusion Appling rhEGF to reinforce wound bed preparation before operation could make subsequent treatment more effective and improve the cure ratio of operation with decreasing complications and morbidities. And more, dissecting under fascia possesses the advantages of easiness to perform and rich blood supply.The method of appling rhEGF with direct polymerizing suture is a simple, high efficient approach for the first repairment of sacrococcygeal decubitus ulcers grade Ⅲ, especially desirable for the elderly.

Objective To study the protective effect and mechanism of Inonotus obliquus polysaccharide on liver injury induced by isoniazid( INH) combined with rifampicin( RFP) in mice. Methods Forty-eight mice were randomly divided into six groups ( control, model, huganpian, Inonotus obliquus polysaccharide at low, middle, and high dose ) . The mice were administered orally with isoniazid and rifampicin simultaneously except the control. After 2 h,the control and model groups were administered with normal saline,and others were treated with huganpian and Inonotus obliquus polysaccharide,respectively,once a day for 2 weeks. The liver index and serum levels of ALT and AST,malondialdehyde(MDA),superoxide dismutase(SOD) and glutathione peroxidase( GPx) were measured. Pathology examination of liver tissue was performed. Results The activities of ALT and AST, liver index, content of MDA in liver homogenate of mice treated with Inonotus obliquus polysaccharide and huganpian decreased obviously, while the liver SOD activity increased. Histopathological exzamination showed that Inonotus obliquus polysaccharide alleviated the degeneration and necrosis of hepatic cells. Conclusion Inonotus obliquus polysaccharide shows protective effects on mice with hepatic toxic injury induced by isoniazid and rifampicin,which maybe due to its antioxidation effect.

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 assess the application of three-dimensional digital subtraction angiography (3D-DSA) in evaluation of ruptured intracranial aneurysm after clipping and to discuss the different variable use of vol-ume rendering(VR), gradient rendering (GR) and maximum intensity projection (MIP). Methods From January 2011 to December 2012 , 88 patients with 92 ruptured intracranial aneurysms were treated with clipping using titani-um clips in our hospital and followed up by both 2D-DSA and 3D-DSA. Residual aneurysms , Clips place, clips and parent arteries and stenosis of parent arteries were evaluated by volume rendering (VR), gradient rendering (GR) and maximum intensity projection (MIP). Results Among 92 clipped aneurysms, 23 residual aneurysms were found by 3D-DSA. Residual aneurysms were recorded according to the Sindou grade: 15 of gradeⅠ, 3 of gradeⅡ, 4 of grade Ⅲand 1 of grade Ⅳ. Three patients of grade Ⅲand 1 of grade Ⅳwith residual aneurysms were retreated by clipping or coiling, and 1 patient of grade Ⅲ was dead with rupture of residual aneurysm. The clips and number of clips were clearly visualized , and relationship between the clips and the aneurysms was well demonstrated by VR, GR and MIP images. VR, GR images showed the remnants clearly. Three-dimensional digital subtraction angiography did not showed accurate details of the stenosis of parent arties which required an analysis of 2D-DSA. Conclusion Three-dimensional digital subtraction angiography can be used for definite evaluation of resid-ual aneurysms after clipping, especially by VR, GR images. It is helpful to manage the residual ruptured aneurysms.
