The recombinant fusion protein staphylokinase-hirudin(rSFH) was purified from the high density-fermented engineered E.coli by means of ion-exchange chromatography (IEC) and gel filtration (GF). The purity of rSFH reached to more than 98% determined by RP-HPLC and SDS-PAGE, and the yield was up to 0.7g per liter of fermentation broth. The analysis of homologous dimmer of rSFH appeared during the purification and calculation of the surface hydrophobic area had been carried out by means of hydrophobic chromatography and MALD-TOF. The influence of sodium chloride and temperature on the behavior of rSFH reversible dimerization was analyzed by high performance sized- exclusive chromatography(HPSEC). It is concluded that the hydrophobic interaction played an important role in the reversible dimerization of rSFH.

ObjectiveTo study the expression changes of peripheral blood monocyte human leukocyte antigen DR (HLA-DR) in patients with severe craniocerebral injury,and investigate the correlation between HLA-DR expression and infection and prognosis.MethodsNinety patients with craniocerebral injury were selected as experimental group and were divided according to the Glasgow coma scale (GCS) score after hospitalization into experimental group 1 (GCS score 13-15 scores ),experimental group 2 (GCS score 9-12 scores) and experimental group 3 (GCS score 3-8 scores) with 30 patients each,which were moderate,medium,severe craniocerebral injury,respectively.Thirty healthy people were chosen at the same period as control group.The HLA-DR expression of experimental group was detected after 1,3,7 and 14 d of admission by flow cytometry,and the HLA-DR expression of control group was detected on the day they got physical examination.The rates of infection,cure,disability,vegetative state and mortality were counted after 30 d of admission.ResultsThe HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7,14 d of admission were (28.11 ± 2.37),(26.45 ± 1.63),(27.75 ± 1.83),(27.15 ± 2.17) MCF and (29.34 ±2.07),(27.55 ± 1.63),(28.42 ± 1.94),(29.46 ±2.12) MCF,which had no statistical difference compared with that in control group [(29.18 ± 1.91 ) MCF](P＞ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7 d of admission and control group had statistical differences compared with those in experimental group 3 after 1,3,7 d of admission [(18.02 ± 1.78),(16.05 ± 1.97 ),(20.76 ± 1.65) MCF ] (P ＜ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 14 d of admission and control group had no statistical significance compared with that in experimental group 3 after 14 d of admission [ (26.13 ± 2.15) MCF](P＞ 0.05).The infection rates of experimental group 1,experimental group 2 and experimental group 3 were 0,3.6％(1/28),82.8％(24/29),respectively,while the cure rates were 100.0％ (30/30),100.0％ (28/28),10.3％ (3/29),the disability rates were 0,0,41.4％ (12/29),the vegetative state rates were 0,0,20.7％ (6/29),and the mortality were 0,0,27.6％ (8/29).There was no statistical significance in the rates of infection,cure,disability,vegetative state and mortality between experimental group 1 and experimental group 2 (P＞ 0.05 ).While there was statistical differences in the rates of infection,cure,disability,vegetative state and mortality among experimental group 1,experimental group 2 and experimental group 3 (P ＜ 0.05).ConclusionsThe HLA-DR expression changes of patients with moderate and medium craniocerebral injury after 1,3,7,14 d of admission are not significant.The HLA-DR expression of patients with severe craniocerebral injury begins to decline from 1 d after injury,declines obviously at 3 d,increases from 7 d,returns to normal level at 14 d.The decline of HLA-DR expression in patients with severe craniocerebral injury is correlated with the infection,and predicts poor prognosis.

Objective To investigate the efficacy and safety of isosorbide mononitrate sustained release tables plus vinorelbine and cisplatin in patients with previously untreated advanced non-small-cell lung cancer (NSCLC).Methods One hundred and ten patients with stage ⅢB-Ⅳ NSCLC were randomly assigned to group A (57 cases) and group B (53 cases) by random mumber table.Patients in group A were treated with vinorelbine 25 mg/m2 on the first and eighth day and cisplatin 25 mg/m2 on day 2-4,with transdermally applied isosorbide mononitrate sustained release tables (40 mg,daily for 8 days),and patients in group B were treated with vinorelbine and cisplatin.Response to treatment was assessed by RECIST1.1 and adverse effect was assessed by NCI-CTC(3.0).Results The response rate in group A (58.2％,32/55 patients) was significandy higher than that for patients in group B (30.8％,16/52 patients; x2 =8.120,P =0.004).Median TTP and median OS in group A were longer than those in group B (8.2 vs 5.8 months,x2 =10.684,P =0.001 ; 11.6 vs 9.0 months,x2 =11.231,P =0.001).While,patients with squamous carcinoma showed better response to chemotherapy (RR =2.438,95％ CI:1.136-5.231,P =0.022).Adverse effect difference was not significant between group A and group B,except headache.The rate of grade 1 to 2 headache in group A (34.5％ ; 19 of 55 patients) was significantly higher than that in group B (3.8％ ; 2 of 52 patients; P ＜0.001).Conclusion Use of isosorbide mononitrate sustained release tables combined with vinorelbine and cisplatin may improve overall response,TTP and OS in patients with advanced stage NSCLC.

OBJECTIVETo investigate the character, diagnosis and treatment of multiple-level fractures of the cervical spine.

METHODSForty-three patients (38 male, 5 female) with multiple-level fractures of the cervical spine were retrospectively analysed in our hospital from 1988-2001.

RESULTSAmong 36 patients with multiple contiguous fractures of the cervical spine, 32 cases were injured at low cervical spine; 7 patients were non-contiguous spinal fractures in which there were 5 cases injured at upper and lower cervical spine. The frequently injured sites were vertebral body (31 patients), laminae (25 patients), spinous process (9 patients), vertebral arch (4 patients), transverse process (5 patients), lateral mass (5 patients); level frequently affected were C(4), C(5), C(6) and C(7); 21 patients were treated with anterior vertebrectomy and fusion, 10 patients with posterior laminectomy and fixation, 2 patients with both anterior and posterior decompression and fixation. 60.5% were flexion-compression injury. 10 patients with conservative treatment.

CONCLUSIONSContiguous type was more common than non-contiguous type in multiple level cervical spinal fractures; Injured sites always located at lower cervical spine in contiguous cervical fractures different from that fractures of atlas, axis and lower cervical spine in non-contiguous type; Unstable segments and level of spinal cord injury were at lower cervical spine; Operations must obtain both decompression and stability of spine.

OBJECTIVETo investigate the characteristics of microbial degradation of aniline by a stable bacterial consortium.

METHODSThe bacterial consortium was isolated from activated sludge treating chemical wastewater using aniline as the sole source of carbon and nitrogen by enrichment and isolation technique. The biomass was measured as optical density (OD) at 510 nm using a spectrophotometer. Aniline concentrations were determined by spectrophotometer. The intermediates of aniline degradation were identified by GC/MS method.

RESULTSThe bacterial consortium could grow at a range of aniline concentrations between 50 and 500 mg/L. The optimal pH and temperature for aniline degradation were determined to be 7.0 and 30, respectively. The presence of NH4NO3 as an additional nitrogen source (100-500 mg/L) had no adverse effect on bacterial growth and aniline degradation. The presence of heavy metal ions, such as Co2+, Zn2+, Ni2+, Mn2+ and Cu2+ had an inhibitory effect on aniline degradation.

CONCLUSIONSThe isolated bacterial consortium can degrade aniline up to 500 mg/L effectively and tolerate some heavy metal ions that commonly exist in chemical wastewater. It has a potential to be applied in the practical treatment of aniline-containing wastewater.

To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

OBJECTIVETo investigate the mechanism of Hangman's fracture and its clinical manifestation and treatment.

METHODSTen patients with Hangman's fracture treated at our hospital from 1988 to 2001 were analysed.

RESULTPatients were injured by motor vehicle accidents (7 patients), object hitting on the head (1), and fall (1). Injuries were classified as type I (1 patient), type II (5), type IIa (2) and type III (2).

CONCLUSIONSMotor vehicle accident and fall are major causes of Hangman's fracture with neurological deficits but limited motion and neck pain. Hangman's fracture is easily diagnosed using lateral cervical X-ray and CT. Hangman's fractures of types I, II and IIa can be treated conservatively, but those of type III or spinal cord injury require surgical stabilization.

Objective To probe the clinic significance ofintraopcrative ultrasonography in brain tumor resection. Methods The intraoperative ultrasonography, adopted in the brain tumor resection of 29 cases, assisted the brain mantle operative approach and the rumor resection monitoring through acquiring the tumors' position, the hemisphere, the internal structure and the adjoining with blood vessels.After the operation, ultrasonography was performed again to observe the tumor surviving. Results The tumor detection rate with intraoperative ultrasound in 29 cases was 100% and best approach was chosen to accurately locate the tumor according to the tumors' position and the hemisphere. Meningiomas got abundant blood supply and were often closely correlated to the sinuses, therefore, preoperative detections of the blood supply and the possible erosion of the sinus wall of meningiomas was performed to provide basis for rapid repair and to shorten the operation time. Repeated detection on the surgery hemisphere and residue detection were performed to help maximize the glioma resection, particularly the functional glioma resection. Conclusion Preoperative color Doppler ultrasound can accurately locate tumor tissue, suggesting the best surgical approach; intraoperative ultrasonography, assisting in the resection of brain tumors, can improve the operation safty and decrease the happening of trauma.
