A 1.8 kb HinfI fragment carrying the chitinase gene(chiA) from Serratia marcescens was isolated from the plasmid pLCHIA and was inserted into the SmaI site downstream of the strong Ptac promoter in the expression vector pKK223-3,yielding the plasmid pKChiA.The 2.1 kb PtacChiA fusion fragment was excised by BamHI from the plasmid pKChiA and was inserted into the single BamHI site present within the plasmid pMC71A,thus generating the plasmid pMChiA.High levels of chitinase were produced by the E.coli strains HB101 and JM105 carrying the plasmid pKChiA or the plasmid pMChiA,with the amount of production were higher 1～3 fold than that produced by the strains carrying the plasmid pLCHIA.

Objective To investigate the renal angiographic manifestations of severe hemorrhage following minimally invasive pereutaneous nephrostolithotomy (MPCNL), and to evaluate the technique of super-selective renal arterial embolization in treating the condition. Methods Forty-eight cases of severe hemorrhage following MPCNL treated with super selective renal arterial embolization in our department were retrospectively reviewed. The angiographic findings, results and complications of embolization procedures were analyzed. Results Two cases were of acute hemorrhage immediately after MPCNL, and the other 46 cases were of delayed hemorrhage 2 to 7 days after MPCNL. Of these 48 cases, 25 (52.1%) showed simple pseudo-aneurysms, 6 (12.5%) pseudo-aneurysms accompanied with arterial-venous shunts, 1 (2.1%) pseudo-aneurysm with extravasated contrast medium, 11 (22.9%) arterial-venous fistulas, 2 (4.2%) extravasated contrast medium from arterial branches, 1 (2.1%) renal capsular branches varix, 2 (4.2%) no lesion detected. Successful super-selective embolization was achieved in all 46 positive cases, and renal hemorrhage was stanched consequently. Polyvinyl alcohol foam embolization particles (PVA), gelfoam and coils were used in the procedures (PVA in 18 procedures, PVA +coil in 5, gelfoam in 10, geffoam + coil in 11, PVA + gelfoam + coil in 2). Post-embolization syndrome of various degrees were seen in all treated patients. A slight rise in blood creatinine levels was observed in 12 cases. Conclusion Super selective renal arterial angiography and embolization is the treatment of choice in patients who suffered severe hemorrhage due to MPCNL.

OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.

Knee osteoarthritis is one of the common type of arthropathy, the clinical stage of the typical patients belongs to the middle-late stage, so it urges to improve the early diagnosis. At present, magnetic resonance imaging is most used in clinical diagnosis of knee osteoarthritis, and with the development of different MRI sequences, the sequences of early articular cartilage lesions are used in clinic. In the early diagnosis of knee osteoarthritis, the simple and practical methods such as ultrasonography is becoming a trend, and the specific biomarkers of early knee osteoarthritis have become the hot research. This overview article outlined the methods of early diagnosis from the ultrashort echo time MRI, ultrasonography and biomarkers.

The epidemic of rabies has rapidly increased and expanded in Yunnan province in recent years.In order to further analyze and understand the etiological reasons for the rapid expansion of rabies in Yunnan,a strain of rabies virus CYN1009D in Yunnan was isolated,and the complete genomic sequencing was carried out,and the bioimfomative analysis on genes/encoded proteins and phylogeny with reference to sequences in GenBank was performed.The complete genome of CYN1009D was 11923 nt in length and belonged to genotype I.The genes encoding different structural proteins were all conserved in their lengths,in comparison to other strains in China.The amino acid sequence was conserved at different antigen sites of NP,but the variation was detected at the secondary phosphorylation site of position 375; variations were also detected in the phosphorylation sites at positions 63-63 and 162 of PP; the sites playing important roles in virus synthesis,budding and viral morphology in MP were conserved; two glycosylation sites were detected at Asn37 and Asn319in GP,the neutralizing antigen sites in GP were conserved; the initial amino acid of LP (ML) was different from that of most of the strains in China (MM); the variations in G-L region in the intergenic region were significant.The phylogenic tree showed that CYN1009D has a closer genetic relationship to the strains in Southeast Asia,indicating that prevention and control on rabies in borderland areas should be reinforced meanwhile efforts are made to control rabies in China.

Objective To discuss the meanings and methods of the screening, diagnosis and treatment of the left subclavian artery stenosis before the coronary artery bypass grafting (CABG). Methods A total of 612 patients intend to perform coronary artery bypass grafting in Tianjin Thoracic Hospital,and who were with severe stenosis or occlusion with left subclavian artery were screened by non invasive arteriosclerosis before operation. The diagnosis was confirmed by computerized tomography angiography(CTA),then the stenting angioplasty to the left subclavian artery was performed.The off-pump bypass surgery with the left internal thoracic artery(LITA)-left anterior descending artery (LAD) bypass was performed one week after operation.Results The CTA and digital subtraction angiography(DSA)confirmed the results of the left subclavian stenosis according to the non-invasive artery testing.All the 5 patients were performed with the stenting angioplasty to the left subclavian artery successfully,and the residual stenosis rate was<10%.The clinical symptoms were markedly improved after operations in all symptomatic patients,and the systolic pressure difference was<20 mmHg in two upper extremities.The blood flow was enough in LITA during the LITA-LAD bypass.The angina pectoris was improved after the operation. No coronary-subclavian artery steal phenomenon occurred. Neither stroke, myocardial infraction nor death occurred during perioperative period.All the patients were followed up for a time of 6-12 months,and the average time was about 10 months.No posterior circulation,upper limbs or myocardial ischemia occurred,and the systolic pressure difference was<20 mmHg in two upper extremities.Conclusion The non-invasion testing is of unique value in the screening of the left subclavian artery stenosis.
