0.05).Conclusion:The CT perfusion parameters can be regarded as a surrogate marker of tumor angiogenic activity,which is a useful method in estimating the degree of angiogenesis.

OBJECTIVE:To compare clinical efficacy of bivalirudin vs. tirofiban combined with heparin in the treatment of acute ST elevation myocardial infarction (STEMI) complicated with diabetes mellitus (DM). METHODS:195 patients diagnosed as STEMI complicated with DM were selected for retrospective study,and divided into bivalirudin group(100 cases)and tirofiban group(95 cases)according to the different treatment plan. All patients received emergency PCI within 12 hours and conventionally took aspirin and clopidogrel before and after PCI. Bivalirudin group was given bivalirudin 0.75 mg/kg intravenously before PCI, and continuous intravenous dripping of 1.75 mg/(kg·h)till the end of operation. Tirofiban group was given heparin 100 U/kg and ti-rofiban 10 μg/kg intravenously before PCI,and continuous intravenous dripping of 0.75 μg/(kg·h)tirofiban for 36 h. Postoperative reperfusion indexes,UCG monitoring indexes and safety were compared between 2 groups,and the content of serum BNP were compared before and after treatment. RESULTS:For the TIMI grade,TIMI frame count,the peak of CK-MB and peak time,ST segment decline percentage immediately after PCI,contents of serum BNP,LVEF,LVESD,LVEDD 7,30 d after treatment,the differences were not statistically significant between 2 groups (P>0.05). The incidence of MACE events was 36.8% in tirofiban group and 41.0% in bivalirudin group,there was no statistical significance between 2 groups(P>0.05). The incidence of bleeding events was 24.2% in tirofiban group and 7.0% in bivalirudin group,the difference was statistically significant (P<0.05). CON-CLUSIONS:Bivalirudin and tirofiban combining with heparin have same efficacy in the treatment of STEMI complicated with DM,while bivalirudin may significantly reduce the incidence of bleeding events during primary PCI.

Objective:To study the reasons and preventive measure of the effect of human urinary kallikrein on blood pressure in the treatment of acute cerebral infarction.Method:Documents about the effect of human urinary kallikrein on blood pressure of pre-clinical study and the phaseⅠ-Ⅲclinical trials were collected and analyzed in combination with the related information of the phaseⅣclinical trial from our hospital.Result:The rate and concentration of medication in combination with ACEI were the reasons for the effect of human urinary kallikrein on blood pressure.Conclusion:Controlling the rate and concentration of medication and forbidding the combined use of ACEI from the 72hr before the medication and the 24hr after it can prevent hypotension caused by human urinary kallikrein.

Background Pseudoexfoliation syndrome (PEX) has a high incidence in Uygur population and usually leads to secondary glaucoma and complicated cataract.The abnormal change of lens tissue and degeneration of zonular fibers bring a lot of difficulties for phacoemulsification (phaco) with intraocular lens implantation,especially stop-and-chop phaco technique.Prechop technique is a new choping technology,but its application in PEX with cataract is less.Objective This study was to compare the efficacy and safety of pre chop phaco technique and stop-and-chop phaco technique for PEX combined cataract.Methods A randomized controlled Clinical trial was designed.Forty-one eyes of 41 patients with PEX combined cataract of Ⅲ degree of nucleus were enrolled in People's Hospital of Hetian District from March 2015 to January 2016.The patients were randomized into the prechop group and stop-and-chop group according to random nubmer table,and cystotome-assisted prechop phaco surgery and stop-and-chop phaco surgery were performed in different groups,respectively.The effective phaco duration,corneal endothelium loss rate,cornea edema eye number after operation,vision outcomes and complications were compared between the two groups.Results The mean effective phaco duration was 14.0 (13.0,16.5) minutes and 18.5 (16.5,24.0) minutes in the prechop group and stop-and-chop group,with a significant difference between them (Z =17.354,P ＜ 0.01).The corneal endothelial cells were (2 101.90 ± 209.08)/mm in the prechop group,and the number was similar to (2 002.30 ± 207.04)/mm of the stop-and-chop group (t =-1.530,P =0.134).Corneal endothelial cell lossing rate was (8.27±2.23)％ in the prechop group,which was lower than (13.09±4.26)％ in the stop-and-chop group (t =3.810,P =0.001).The BCVA was better in the prechop group than that in the stop-and-chop group in postoperative day 3 (P =0.044),and the corneal edema degree was not signigicantly different in postoperative day 1 and day 3 between the two groups (P=0.221,0.446).Intraoperative complication was rapture of zonule and occurred in 1 eye and 2 eyes in the prechop group and stop-and-chop group,respectively.Conclusions Compared with the stop-and-chop phaco technique,the prechop phaco tequnique can decrease intraoperative complication,lighten the postoperative damage of corneal endothelial cells and accelerate visual rehabilitation in PEX combined with cataract patients.

ObjectiveTo assess the feasibility of seeding adipose-derived stem cells (ADSCs) onto bladder acellular matrix grafts (BAMGs) for bladder reconstruction in a rabbit model.MethodsAutologous ADSCs were isolated,expanded and identified by flow cytometry.In the experimental group,ADSCs were seeded onto BAMGS for reconstructing bladder defects in 12 male rabbits.Unseeded BAMGs were used for bladder reconstruction in the control group of 12 rabbits.Cystography was performed at 24 weeks after grafts implantation.Following cystography,the animals were scarified and grafts were harvested； H&E and immunohistochemical staining were performed with cytokeratin AE1/AE3,smooth muscle α-actin and S-100 markers.ResultsFlow cytometry demonstrated that the ADSCs expressed CD90,CD44,CD105,CD166 and CD34,but not CD45 or CD106.The cells demonstrated good biocompatibility with BAMGs.At 24 weeks,in the experimental group,the reconstructed bladders reached a mean volume of (94.68 ± 3.31 )％ of the precystectomy bladder capacity.Complete regeneration of smooth muscle and nerve tissue was evident.Regenerated SMCs,urothelium and nerve cells stained positively for α-smooth muscle actin,AE1/AE3 and S100.In the control group,the mean bladder volume was (69.33 ± 5.05 )％ of the pre-cystectomy volume.Histologically,the control group was characterized by multi-layered urothelium without evidence for organized muscle or nerve tissue.Conclusion The tissue engineering bladder constructed by ADSCs and BAMG can be used as an ideal biomaterial to replace and repair the bladder.

Objective To compare GM260 portable blood glucose meter and AU5821 automatic biochemical analyzer in order to prove the accuracy of GM260 and its applicability for clinical use.Methods Totally 20 pieces of EDTA-K2 anticoagulative specimens and 23 GM260 meters were numbered,and each specimen underwent examinations by both GM260 and AU5821,then the bias between the two kinds of devices was calculated.Results The maximal bias between GM260 and AU5821 was 0.47 mmol/L and all the meters had the bias between-0.83 and 0.83 mmol/L in case of 5 specimens with the glucose concentration less than 4.2 mmol/L;the maximal bias between GM260 and AU5821 was 18.07％ and all the meters had the bias between-20％ and 20％ in case of 15 specimens with the glucose concentration not less than 4.2 mmol/L;the examination results by GM260 all accorded with industrial standard.The results by GM260 were lower than those by AU5821,and the maximal negative deviation was-13.43％.Conclusion Portable blood glucose meter can only be used for screening,and automatic biochemical analyzer is the preferred device for diabetes diagnosis.

Objective To evaluate serum soluble intercellular adhesion molecule-1 (sICAM-1) before and after lung transplantation for diagnosing acute rejection. Methods Biotin-streptavidin time resolved fluoroimmunoassay (BSA-TRFIA) was used to detect the concentration of serum sICAM-1 before and after lung transplantation in 26 patients. All patients were divided into stable lung transplantation group (n =16), acute rejection group (n =4) and infected group (n =6). The serum level of sICAM-1 in those groups was compared with that of the control group ( n = 30 ) by the non-parametric rank sum test ( KruskalWallis H test). Results No significant difference was found for serum sICAM-1 among the three groups and the control group before operation: (357.07 ± 220.01 ), ( 396. 18 ± 136.25 ), (468.95 ± 85.48 ) μg/L vs(348.63 ±69. 12) μg/L, H=6. 0436, P ＞0.05. However, when rejection and infection happened after operation, the serum sICAM-1 increased in the acute rejection group (455.53 ± 126.51 μg/L) and decreased in the infection group (146.43 ± 327.11 μg/L), and the level in the stable transplantation group was (274.23 ± 157.53 ) μg/L (H = 21. 8994, P ＜ 0.01 ). Conclusion Serum sICAM-1 level might be a potential marker to differentiate acute rejection from infection after lung transplantation.

OBJECTIVETo summarize clinical results of the microdecompression for the treatment of intraforaminal lumbar disc herniations.

METHODSFrom September 2005 to May 2013,16 patients( 12 males, 4 females)with intraforaminal lumbar disc herniations underwent microdecompression, ranging in age from 32 to 56 years old with a mean of 38.6 years old. The lumbar disc herniations were located at L(3,4). in one patient, L(4,5) in 10 cases and L5S1 in 5 cases.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months, with a mean period of 36 months. According to Macnab evaluation, 12 cases got an excellent result, 4 good. No apparent complications related to the technique occurred. Satisfactory clinical results were obtained in this series.

CONCLUSIONMicrodecompression may be particularly useful in the treatment of intraforaminal lumbar disc herniations. The microdecompression procedures are more likely to be well tolerated by older patients.
