The efficiency of cold storage red blood cells (CSRBC) or whole blood at -80 degrees C used in 27 Rh (D) negative patients during surgical operation was reported. The Rh (D) negative patients received the transfusion of CSRBC or whole blood stored at -80 degrees C for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K+, Na+, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P > 0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K+ and blood Na+ was normal with the difference being not significant before and after operation (P > 0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P > 0.05). It was suggested that CSRBC or whole blood at -80 degrees C could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.

Objective To investigate the application of expanded p01ytetrafluoroethylene(ePTFE)grafts in upper arm to build arteriovenous aCCeSS for hemodialysis. Methods ePTFE graft vascular access was built in the upper arm in 20 uremia patients.Three operation strategies were applied according to the reference,including loop grafts connected axillary artery and axillary vein,straight graft connected axillary artery and elbow basilic vein,and bridge connected elbow brachial artery and axillary vein. Results Twenty operations were successful and after 6-8 weeks the fistula of all cases were used in hemodialysis.The blood flows were 220-300 ml/min without re-circulation found.Conclusion ePTFE graft arteriovenous vascular access in the upper arm could be an alternative for hemodialysis patients who are difficult to build native arteriovenous fistula.

OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

The national examination of doctors' qualification is the examination which assesses the medical students' knowledge and skills for doctors' work. This paper introduced autorities concerned, implementing agencies, examination forms and procedures, examination contents and keypoints, pass-ing criteria and matters needing attention of national examination of doctors's qualification be tween Canada and Australia expecting to provide references for the revolution of Chinese Examination of Doctors' Qualification.

Objective To investigate the pathogenetic mechanism of ubiquitin-proteasome dysfunction in a model of Parkinson's disease(PD),which can provide the theoretical basis for PD.Methods After establishment of PD model induced by PSI in PC12 cells,proteins of untreated(DMSO) and PSI-treated PC12 cells were extracted 36 h after incubation,and then the maps of the extracted proteins were established by DIGE system.The altered protein spots were identified with MALDI-TOF Pro MS and database searching.Results Thirty-six treatment of PC12 cells with PSI induced the appearance of cytoplasmic Lewy body-like eosinophilic inclusions and apoptosis.The percentage of apoptotic cells was 25.53%.ERp29 were identified by MALDITOF Pro MS.The expression of ERp29 decreased in treatment group,compared with normal group(P

OBJECTIVEThis aimed to investigate the effect of specific sequence oligodeoxynucleotide MT01 on the biological properties of osteoblasts invaded by Porphyromonas gingivalis (P. gingivalis ) by evaluating proliferation, cell cycle, and apoptosis.

METHODSMG63 osteoblasts were recovered and incubated with MT01, CpG ODN, metronidazole (MNZ), and gentamicin (GEN) for 3 h. P. gingivalis (the multiplicity of infection was 100:1) was added subsequently and cocultured for another 24 and 48 h. Cells with PBS comprised the blank group, whereas cells with P. gingivalis comprised the negative controls. Six experimental groups were established: PBS group, P. gingivalis group, MT01+P. gingivalis group, CpG ODN+ P. gingivalis group, MNZ+P. gingivalis group, and GEN+P. gingivalis group. The proliferative ability was measured by methyl thiazolyl tetrazolium assay, and the percentages of apoptosis and cell cycle were examined by flow cytometry.

RESULTSCompared with the blank group, proliferation increased significantly in the MT01+P. gingivalis group (P < 0.05). The ratio of cells was lower at the G₁ phase and higher at the S phase in the MT01+P. gingivalis group compared with the results in the P. gingivalis group (P < 0.05). Early cell apoptosis in the MT01+P. gingivalis group was significantly lower than that in the P. gingivalis group (P < 0.05).

CONCLUSIONMT01 can promote the proliferation, reduce the ratio of the G₁phase, increase the ratio of the S phase, and inhibit the early apoptosis of osteoblasts invaded by P. gingivalis.

ObjectiveTo analyze the association of human urate transporter 1 ( hURAT1 ) gene promoter single-nucleotide polymorphisms(SNPs) with primary hyperuricemia ( HUA ) in Chinese Han people.MethodsA total of 215 patients with HUA and 323 healthy subjects were chosen to be investigated of SNP of hURAT1 promoter by PCR and sequencing.ResultsFive SNPs were identified,including-454A/T,-434T/C,-382C/T,-87C/T,and + 118G/A.Pairwise linkage disequilibrium analysis displayed a high linkage disequilibrium between the five SNPs ( r2 =0.99).In HUA group,the heterozygous genotypos ( AT,CT,CT,CT,AG ) frequencies were significantly lower than those in control group ( P＜0.05 ).Logistic regression analysis showed that the heterozygosis genotypes ( AT,CT,CT,CT,AG) were protective factors of HUA ( OR 0.68-0.75 ).The minor allele ( T,C,T,T,A ) frequencies for both SNPs were significantly different between two groups ( P =0.022,P =0.038 ).ConclusionThese findings indicate that -454A/T,-434T/C,-382C/T,-87C/T,and + 118G/A SNPs of hURAT1 gene promoter area are associated with HUA in Chinese Han population.

Objective To evaluate the results of rotary self-locking intramedullary nail (RSIN) for treating long tubular bone fracture of extremities, and discuss the current problems. Methods One hundred and twenty-two patients with long tubular bone fracture of extremities,including 59 femoral fractures,57 tibial fractures and 6 humeral fractures,who had been treated by RSIN were retrospectively investigated. Results All of the patients achieved clin-ical healing,with an average time of 24 weeks. Nobody was found to appear maluniun,infection and the break of inter-nal fixture. Internal fixations were removed after the fracture healing,with an average time of 14 months. It was diffi-cult to remove the internal fixations in 5 cases, and one case refractured after removing the internal fixations. Conclu-sion RSIN has the advantages such as easy operation,less trauma,no pendulum effect,early motion after operation and so on, except the characters of general interlocking intramedullary nail such as anti-rotation, anti-crispition and anti-displacement.
