Objective To evaluate the biomechanical characteristics of the long U-shaped hollow pedicle screw system for percutaneous fixation of thoracolumbar fractures.Methods Models of vertebral compression fracture were created by flexion in 8 fresh cadaveric samples of thoracolumbar spine.The models were divided into 2 equal groups according to the fixation system applied.In group A conventional pedicle screws were used while in group B long U-shaped hollow pedicle screws were used.The yield compressive strength,axial compression stiffness,bending stiffness,torque and torsional stiffness of all the fixated spines in the 2 groups were tested by the bio-mechanical electrical measurement and compared as well.Results The conventional pedicle screws and long U-shaped hollow pedicle screws showed no significant differences regarding yield compressive strength (3450.02 ± 110.03 MPa vs.3430.04 ± 102.12 MPa),axial compressionstiffness (407.52 ± 33.02 N/mm vs.395.04 ± 26.46 N/mm),bending stiffness (305.14 ± 26.53 N · cm/Degvs.295.12±23.80 N · cm/Deg),torque (6.45±0.25 N · m vs.6.25±0.21 N · m) or torsional stiffness (0.54±0.04N·cm/Degvs.0.52±0.03N·cm/Deg) (P＞ 0.05).Conclusion The long U-shaped hollow pedicle screw system can satisfy the biomechanical requirements for fixation of thoracolumbar fractures and can function as well as the conventional pedicle screw system.

Magnetic Resonance Imaging (MRI) can form a three-dimensional positioning anatomical imaging.By comparing the tumor volume and signal intensity changes,there is great value of MRI in the assessment of the efficacy of cervical cancer.With the development of imaging,magnetic resonance diffusion weighted imaging (DWI),magnetic resonance spectroscopy (MRS) can provide qualitative and quantitative information of the cellular level,which reflects changes in the treatment of tumor cells.Magnetic resonance imaging can predict early locally advanced cervical cancer neoadjuvant chemotherapy,thus providing an important basis for individualized treatment of patients.

Objective: To investigate the effect of oat on blood glucose、insulin and serum lipid in aged patients with type-2 diabetes mellitus.Methods: Blood glucose(FBG,PBG),insulin(F-INS,P-INS) and serum lipid(TG,TC) were determined in eighty aged patients with type-2 diabetes mellitus before and after 50-100 g oat intake. Results: FBG,PBG and P-INS were decreased significantly(P

AIM To study the hepato-protection of indole-3-carbinol (I3C), one of glucosinolate compounds in cruciferous vegetables, on ethanol-induced hepatotoxicity. METHODS Ethanol 50 mmol?L -1 was used to induce hepatotoxicity in precision liver-cut slices of rats. The release of glutamic pyruvic transaminase(GTP), glutamic oxaloacetic transaminase (GOT), lactate dehydrogenase (LDH) and glutathione S-transferase (GST) into culture medium, and aniline hydroxylase (ANH) and alcohol dehydrogenase (ADH) in cytosol of hepatocytes in the precision liver-cut were measured with different doses of I3C. The histopathological observation of liver slices was also done to evaluate the effect of I3C. RESULTS The release of GTP, GOT, GST and LDH in the medium increased significantly when the slices were treated with 50 mmol?L -1 ethanol for 4 h. I3C at concentrations of 100～400 ?mol?L -1 effectively reduced the release of GTP, GOT, GST and LDH in the medium of ethanol-treated slices. Meanwhile, the activities of cytosol ANH and ADH decreased to the normal levels. The histopathological changes of liver slices induced by ethanol were lessened by I3C treatment. CONCLUSION I3C can markedly protect rat liver slices from ethanol-induced hepatotoxicity, which partly results from the change of ethanol metabolism in liver.

Total glucosides of paeony (TGP)is used to treat rheumatoid arthritis(RA)as the first immunoregulatory drug in clinic.The efficacy of TGP in treating RA patients is definite, which is accompanied with mild adverse reaction and slow effects simultaneously.Paeoniflorin (Pae ),the main constituents of TGP,has a bioavailability of 3% ~4%,which may be served as the main reason for its slow effects.Therefore,in this paper,the pharmacokinetics of Pae as well as its influencing factors were re-viewed on basis of pulished papers.In addition,some problems about Pae were also discussed.

Objective To survey the application of diagnosis and implementation of treatment guidelines of cerebrovascular disease( CAD)combined community acquired pneumonia( CAP)in the community of Shenyang. Methods Randomly chose 7 hospitals in different levels in districts and counties of Shenyang,and made a retrospective survey on the treatments of CAD combined CAP from Oct. 2009 to Jun. 2012 to clear the implementation. Meanwhile,the collected cases were divided into in compliance with guidelines group and non compliance with guidelines group. The information including clinical stable time,length of hospital stay,efficient treatment,empiric therapy and prognosis with the help of guidelines were collected. Results Four hundred and eighty-eight cases were qualified from collected 532 cases,in which,38. 5% initial diagnosis and treatment was accord with the guidelines formulated by the Respiratory Branch of Chinese Medical Association. The efficiency of initial empirical treatment was 84. 5%. The clinical stable time in compliance with guidelines group was (5. 00 ± 0. 27)d,better than that in non compliance with guidelines group((8. 00 ± 0. 45)d;P=0. 021). The length of hospital stay was(11. 00 ± 0. 25)d in compliance with guidelines group,significantly less than that in non compliance with guidelines group(( 14. 00 ± 0. 53 ) d;P =0. 015 ). The effective rate of patients with respiratory failure in compliance with guidelines group was 90. 9%,higher than non compliance with guidelines group(58. 6%),and the difference was significant(P=0. 026),while there were no significant differences in terms of gender,heart and lung diseases. Conclusion There is the smaller patient proportion that diagnosed and cured in accordance with the guidelines formulated by the Respiratory Branch of Chinese Medical Association. It is no distinctive difference for the efficient treatment of guidelines. But selected antibiotic application according to the guidelines can improve the clinical stable time and hospital stay of CAD combined CAP,as well as reduce invalid cases and reduce the mortality rate. The guidelines need to be further extended.

Objective To investigate the virologic responses to pegylated-interferon alfa-2a (PegIFNα-2a) plus ribavirin therapy for cryoglobulinemia positive chronic hepatitis C in patients with hepatitis C virus (HCV) genotype 1 b.Methods Clinical data on 60 chronic hepatitis C patients with HCV genotype 1b were collected from Huzhou Central Hospital during January 2008 and December 2012.The patients were divided into cryoglobulinemia positive group (n =22) and cryoglobulinemia negative group (n =38),and both received 48-week PegIFNα-2a (180 μg) plus ribavirin treatments.For those who could not tolerate the treatment,PeglFNα-2a was reduced to 135 μg from 12th week.Rapid virologic response (RVR),end of treatment virologic response (ETVR) and sustained virologic response (SVR) in two groups were observed and compared using Chi-square test.Results RVR,ETVR and SVR in cryoglobulinemia positive group were 59.1％ (13/22),81.8％ (18/22) and 31.8％ (7/22),while those in cryoglobulinemia negative group were 55.3％ (21/38),76.3％ (29/38) and 60.5％ (23/38).There was significant difference in SVRs between two groups (x2 =4.674,P ＜ 0.05).For those completed full course of antiviral therapy with 180 μg PegIFNα-2a,the RVR and SVR in cryoglobulinemia negative group tended to be higher than those in cryoglobulinemia positive group,but the differences were not statistically significant (x2 =1.524 and 1.009,P ＞ 0.05).Serious adverse reactions were observed in 9 (40.9％) patients of cryoglobulinemia positive group,while in 11 (28.9％) patients of cryoglobulinemia negative group (x2 =0.887,P ＞ 0.05).Conclusion Cryoglobulinemia may not have considerable impact on virologic responses to PegIFNα-2a plus ribavirin therapy in patients with chronic genotype 1b hepatitis C.

Objective To investigate the efficacy of conservative treatment with laparoscopy for patients with ectopic pregnancy.Methods From January 2000 to December 2005,76 patients with ectopic pregnancy received conservative treatment by laparoscopy in our hospital.The data of the patients were analyzed retrospectively.Results In this series,fenestration of the Fallopian tube was performed on 42 cases,salpingostomy on 21,fimbrial expression on 8,and segmental resection and end-to-end anastomosis on 5.Salpingography showed that the Fallopian tube was patent after the operation in all of the patients.The mean operation time was(58.5?19.4) minutes(ranged from 35 to 105).The serum level of ?-hCG decreased to a normal range in 3 weeks postoperation.Follow-up was available in 61 cases for 1 year,during which 35 of the cases(57.4%,35/61) had intrauterine pregnancy;2(3.3%) had spontaneous abortion,and 2(3.3%) showed ectopic pregnancy;the other 22(36.1%) had no pregnancy.Conclusions Conservative treatment by laparoscopy is safe and effective for ectopic pregnancy.To avoid repeated ectopic pregnancy,?-hCG monitoring after the operation is necessary.
