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 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.

ObjectiveTo analyze the seroepidemiologic of Mycoplasma pneumoniae infection and evaluate antibiotics medication of some positive patients by follow-up. Methods Serodia-MycolⅡ particle agglutination assay was used to detect serum antibodies against Mycoplasma pneumoniae in 3 134 clinically suspected infections. Mycoplasma pneumoniae infection was determined and seroepidemiologic was analyzed by results of the test, including positive antibody rates in whole subjects, in male or female groups, in different seasons or age groups as well as in different sources. Evaluate antibiotics medication of some positive patients by follow-up. The average days of medication were counted, different antibiotics medication and medication effect were analyzed. Results In 3 134 serum samples from clinically suspected Mycoplasma pneumoniae infections, 350 ( 11.2％ ) were tested with positive antibodies. The positive antibody rate in female patients was 12. 3％ ( 198/1 604), which was higher than 9. 9％ ( 152/1 530) in males (X2 =4. 58,P ＜0. 05). The peak season was found in the fourth quarter (October-December) with 13.2％ of positive antibody and the highest positive rate (32. 8％, 45/137 ) was found in school aged (5 -9 years old )children. Samples from pediatrics clinic and ward were tested to have highest positive rates ( 27. 9％ and 26. 5％, respectively ), comparing that from other sources. Infection due to Mycoplasma pneumoniae was identified in 28％ (7/25) of community-acquired pneumonia (CAP) patients, which is higher than other diseases. Based on the follow-up of 91 antibody positive patients, between 5 to 120 days ( mean 24. 2 days )were counted from appearance of clinical symptoms to clinic visiting/testing. 71 of 91 (78. 0％ ) patients was medicated with macrolide antibiotics, 4 (4. 4％ ) with quinolones, 4 (4. 4％ ) with cephalosporin, and the rest 12 ( 13.2％ ) patients were medicated with other antibiotics or only symptomatic treatment. The average period of antibiotics medication was between 3 to 21 days (mean 8. 2 days). Medication effect results by follow-up were cure in 35 ( 38. 5％ ), improvement in 50 (54. 9％ ), and poor responses in 6 (6. 6％ ).ConclusionsMycoplasma pneumoniae positive rate in female patients was higher than in males, and peak rate was found in the fourth quarter and in school aged children. Samples from pediatrics clinic and ward were tested to have highest positive rates. Physicians could choose first line antibiotics according to laboratory test results of Mycoplasma pneumoniae, and gain good effect.

In order to estimate the relationship between iron and the Alzheimer's disease, the behavioral and pathological changes were observed by Morris water maze and immunohistochemical staining respectively after injecting FeC13 into brain ventricle of rats. The apoptosis was tested by flow cytometry and the electron microscopy was used to observe ultrastructural changes. There were significant differences in escape latency of time and distance between normal animals and iron treated rats. Percentage and fluorescence intension (FI) of AnnexinV FITC loaded cells undergoing apoptosis were higher in iron treated rats compared with normal animals. Fawn-coloured products of β amyloid protein were interspersedly distributed in extensive areas of cerebral cortex and hippocampus. Under electron microscope, vacuolate degeneration of neuronal processes with mitochondria degeneration and accumulation of microtubule near vacuolar nucleus were observed in iron treated rats. These results suggest that a local higher concentration of iron in brain may induce Alzheimer-like impairment of intelligence and pathological changes.

Objective To investigate the effect of recombinant human endostatin(rh-Endostatin) combined with transcatheter arterial chemoembolization(TACE) on the growth and metastasis of the implanted hepatic tumor in rabbits.Methods Thirty New Zealand white rabbits were randomly divided into three groups (10 in each group)and VX_2 carcinomas were implanted in the left lobes of the livers. Fourteen days later, a catheter was inserted into the hepatic artery of rabbits with VX2 hepatic tumor and infusion was performed via the hepatic artery using physiological saline (group A), TACE (group B) and rh-Endostatin combined with TACE (group C),respectively. Five weeks later, all ribbits were sacrificed, the body weight and liver weight of animals were assessed, the hepatic index(HI) was calculated, the volume and necrotic area of the implanted tumor were measured. The presence of metastases in the liver, lungs were recorded. Results Five weeks after inoculation, the body weight of all animals decreased, the liver weight increased, His were 10.2±2.8, 8.5±6.1and 6.2±4.4 in groups A, B and C, respectively. The mean volume and necrostic areas of the implanted tumor were (36.2±3.4) cm~3 and (52.0±2.3)% in group A, (23.6±4.5) cm~3 and (63.6±3.5)% in group B, (10.9±5.1) cm~3 and (78.6±4.8)% in group C, respectively. There were statistical significance about tumor volume and necrostic areas of the tumors between group C and group A,B ( P<0.01). The numbers of metastases in the lungs were 50.3±31.3,53.6±35.1 and 16.8±18.4 , and the diameters of metastases in the lungs were (3.6±1.4) mm, (3.8±0.6) mm and (1.2±0.6) mm in groups A, B and C, respectively, the difference between group C versus other groups( P<0.01) was statistically significant. The differences of opportunity, tumor numbers and size of metastases in the liver were statistically significant. (P<0.01).Conclusion Treatment with rh-Endostatin combined with TACE can suppress the growth of tumor and tumor's metastases in lungs inVX2 implanted tumors of rabbits.
