BACKGROUND:Healing time and plaster used in fixed position and fixed time are different between distal radius fractures and scaphoid fracture. When both fractures occur simultaneously, you cannot choose a fixed position and determine a fixed time. One-stage internal fixation for the distal radial fractures and scaphoid fractures simultaneously can obtain a good function. OBJECTIVE:To retrospectively analyze the effects of titanium locking compression plate and Herbert screw fixation for fresh unstable distal radial fractures with scaphoid fracture. METHODS:A total of 12 patients with fresh unstable distal radial fractures combined with scaphoid fracture were treated in the Shanxi Dayi Hospital from November 2011 to June 2014. Al cases received open reduction and locking compression plate fixation of the distal radius, open reduction of scaphoid fracture or percutaneous Herbert screw fixation. Fracture healing was observed during folow-up. At 6 months after treatment, wrist joint function was evaluated with modified McBride score. Range of motion of palmar flexion, dorsiflexion, ulnar deviation, radial deviation, pronation and supination and grip strength were measured. The distal radial shortening (difference in height of styloid process of radius and ulna), and angles of ulnar deviation and palmar tilt were measured with X-ray films. The data of healthy side and affected side were compared. RESULTS AND CONCLUSION:(1) 12 cases were folowed up for 6-24 months. (2) The distal radius and scaphoid fractures healed. The healing time of distal radius was 6-12 weeks, with an average of seven weeks. Healing time of scaphoid fracture was 3-6 months, with an average of 4.2 months. (3) Wrist score was evaluated using modified McBride scoring criteria at 6 months after treatment. There were excelent in 5 cases, good in 6 cases, and average in 1 case, with the excelent and good rate of 92%. (4) No significant difference in range of motion of palmar flexion, dorsiflexion, ulnar deviation, radial deviation, pronation and supination and grip strength, angles of ulnar deviation and palmar tilt, difference in height of styloid process of radius and ulna and modified McBride score was detected between healthy side and affected side (P > 0.05). (5) The median nerve injury in two patients was recovered within 6 months after postoperative exploration decompression. No complications appeared, such as infection, dorsal muscle tendon irritation symptoms, carpal tunnel syndrome, and internal fixation failure. (6) These findings confirm that fresh unstable distal radial fractures with scaphoid fractures can be treated with open reduction of the distal radius and locking plate fixation, open reduction of scaphoid bone or percutaneous Herbert screw fixation, with reliable fixation, high fracture healing rate, and good wrist function recovery rate; the repair effect is satisfactory.

300mg/d)were randomly divided into two groups:①Val group consisted of 20 cases(8M/12F),treated with Val 80~160mg/day.②Ben group 20 cases(9M/11F),treated with Ben 10~30mg/d.A goal of blood pressure(BP)control was 130/80mmHg or less in the two groups.Treatment period lasted for 8 weeks.The levels of UAE were measured by radioimmunoassay before and after treatment.We also measured Bp,fasting blood glucose,glycosylated hemoglobulin.Results After treatment of 8 weeks,Bp values in the two groups declined significantly compared with the pretreatment levels(P0.05).The levels of UAE in the two groups decreased significantly in comparison with pretreatment(P0.05).Val group seems to have lower adverse drug reaction rate.Conclusions The results indicate that Val has similar effects on reducing UAE in DN compared with Ben.And Val has fewer side effects.

[Objective]To investigate the metaphase result of extensive fusion in treatment of spondylolisthesis combined with intervertebral disc degeneration of adjacent joints.[Methods]Seventy-nine cases of lumbar spondylolisthesis combined with intervertebral disc degeneration of adjacent joints were treated with extensive fusion and internal fixation from September 2002 to September 2007.JOA and VAS scores were assessed and compared pre-and post-operatively.X-ray and CT were performed to observe the stabilization of fusion joints,and satisfaction rate from patients was investigated.[Results]All patients were followed up for 2 to 6.5 years(mean,4.6 years).Post-operative JOA scores increased(P

OBJECTIVE To evaluate the antibiotic susceptibility on coagulase negative staphylococci(CNS) in Xiangya Hospital and to investigate the role of slime in the resistance mechanism of biofilms.METHODS To isolate and identify CNS from clinical(specimens).The susceptibility of 15 antibiotics was tested by the disc diffusion method.The quantity of slime(produced) by CNS was measured by the colorimetric method.Slime was isolated from selected strains of CNS and analyzed by SDS-PAGE.The MICs to vancomycin,gentamicin and rifampin were determined with and(without) the addition of extracted slime by a standard microtiter method.RESULTS Of all these 15 antibiotics,the highest resistance to CNS was penicillin,followed by erythromycin and trimethoprim-sulfamethoxazole.CNS was more susceptible to ampicillin/sulbactam and rifampin.None was resistant to vancomycin.All of 158 CNS,except one strain,could produce slime.There was a statistical difference between the quantities of slime produced by CNS that produced high and low quantity slime.However,there was a non-statistical difference of resistance to these 15 antibiotics of above CNS. There was an increase in the MICs to vancomycin and gentamicin,but no in the MIC to rifampin,in the absence of 20mg/ml extracted slime.The extracted slime seemed to be similar to the glycosaminoglycans(GAG);it had mobility similar to that of chondroitin sulfate.CONCLUSIONS CNS can(produce slime) on some condition,universally,then to form biofilms.However,in vitro susceptibility testing(employed) cannot really reflect the susceptibility of bacteria in biofilms in vivo.Slime can increase the MICs to vancomycin and gentamicin because of interference with either the antimicrobial action of these drugs or the(perfusion) of these drugs through the medium to increase the resistance of biofilms.It does not affect the MIC to rifampin.

Purpose:To evaluate the effect and toxicity of gemcitabine cisplatin combination in elderly patients with advanced NSCLC.Methods:32 elderly patients were treaded with Gemcitabine 1 000 mg/m 2 on day 1,8 and DDP 70 mg/m 2 on day 1. The second treatment cycle was given on day 22.Results:Each patient was given at least 2 cycle chemotherapy. All together 134 cycles were given. The overall response rate (the completed response plus partial response) was 43.8%. The main toxicity was bone marrow depression. The proportion of WHO grade 3 4 hemoglobin, leukocyte and thrombocyte decrease cycles was 7.5%, 12.7%, 23.1%, respectively.Conclusions:Gemcitabine cisplatin combination is effective and well tolerated for elderly patients with NSCLC.

Objective To explore the clinical application of microsurgical techniques to therapy the femoral neck fracture in younger patients and prevent the necrosis of femoral head.Methods Seventy-four younger adults,age from 23 to 50,with femoral neck fractures were treated by open veducition,internal fixa- tion and pedicled bone transplantation from Jan.1995 to Dec.2004.All of the 74 patients were reviewed clin- ically and radiologically after an average of 3.2 years.Results In this group,19/74 cases(25.68%)had avaseular necrosis of the femoral head,which were diagnosised after an average of 28.5 months following inju- ry.Despite these results,these patients assessment with Harris system had been very good or good in 55/74 patients(74.32%).Conclusion It's an effective method to decrease the incidence of necrosis of femoral head after management the femoral neck fracture in younger patients by microsurgical techniques.

Objective:To investigate the surface characterization,cell adhension and proliferation of ultrafine grained titanium (UFG Ti) after different sand blasting and acid-etching(SLA).Methods:The billets of UFG Ti and commercially pure titanium Ti(CP Ti) were incised into cylindrical specimens with 7 mm in diameter and 2 mm in height.The specimens were sand blasted at the air pressure of 0.2,0.4,0.6 and 0.8 MPa respectively(n =10) and then acid-etched.The surface morphology,roughness and surface wettability of the specimens were examined.Rat embryo osteoblasts MC3T3-E1 were cultured on the speciments for 1 d,3 d and 5 d respectively,the cell morphology and cell density were observed.Results:The different hierarchical porous topographies were formed on the surface of UFG and CP Ti after modified by SLA.The sizes of blasted holes on the surface and the surface roughness of both materials increased with the increase of blast pressure,but the values of UFG Ti were lower than those of CP Ti correspondingly(P ＜ 0.05).The surface wettability of them was also changed with the blast pressure,but the values of UFG Ti was significantly smaller than those of CP Ti(P ＜ 0.05).When the blast pressure was 0.6 Mpa,the UFG Ti exhibited excellent wettability,the cell density was the highest,the morphology of MC3T3-E1 cells on UFG Ti was superior to that on CP Ti.Conclusion:UFG Ti exhibits proper surface morphology,roughness and excellent wettability,which is more appropriate for adhension and proliferation of MC3T3-E1 cells after modification by SLA at blast pressure of 0.6 Mpa.

Aim To investigate the expression of vascular endothelial growth factor(VEGF) and its receptors in human hepatocellular carcinoma cell lines SMMC7721, HHCC and HepG2. Methods Immunohistochemical staining and reverse-transcriptase polymerase chain reaction(RT-PCR) were used to detect the mRNA and expression of VEGF and its receptors: VEGF-R1(Flt-1) and VEGF-R2 (KDR) in three human hepatocellular carcinoma cell lines, SMMC7721, HHCC and HepG2, as compared with ECV304 cells(human umbilical vein endothelial cells) and L929 cells(mouse fibroblast). Results All three human hepatocellular carcinoma cell lines expressed VEGF protein. Flt-1 mRNA and protein could be detected in SMMC7721 cells while KDR in HHCC and HepG2 cells. Conclusion The expressions of Flt-1 and KDR suggests that VEGF may be an autocrine growth factor for human hepatocellular carcinoma, at least for cell lines in vitro.
