Objective To compare the sensitivity and specificity of neutrophil CD64 and C-reactive protein( CRP) in the diagnosis of bacterial infection by Meta-analysis. Methods A computerized literature search of PubMed,Embase and Science Citation Index Expanded was conducted to retrieve studies related to evaluating the diagnosis value both of neutrophil CD64 and CRP in bacterial infectious diseases before January 2015. The methodological quality of each included study was assessed. The method of statistical analysis was dichotomous Meta- analysis using STATA 12. 0 software. Results Ultimately we included a total of 10 studies with 1 057 specimens in neutrophil CD64 group and 1 063 specimens in CRP group. Neutrophil CD64 compared with CRP in the sensitivity,OR=1. 755,95%CI(1. 041,2. 958),P=0. 035,while in the specifici-ty,OR=0. 620,95% CI(0. 442,0. 870),P=0. 006. Conclusion In the diagnosis of bacterial infectious dis-eases,neutrophil CD64 is better than CRP in the sensitivity,but,CRP is better than neutrophil CD64 in the specificity.

Objective To investigate the diagnosis value of the cytological examination of the cerebrospinal fluid of central nervous system leukemia.Methods Adopting cell smear centrifugal machine to collect the cerebrospinal fluid cells,the cells were stained and examinated under the microscope.Results Fifty-nine children with different type of leukemia had been examinated by 438 times by cerebrospinal fluid.The positive rates of the cases and samples were 15.3% and 8.7%,respectively.Conclusion The cytological examination of cerebrospinal fluid is especially valuable for the early diagnosis ,therapy and relapse of central nervous system leukemia of monitoring.

Objective To observe the clinical efficacy using curette and stripping wire method in treating diabetic foot. Methods 36 hospitalized patients diagnosed as diabetic foot were enrolled, and 18 of them were chosen as the experimental group according to random digital table method who was treated with medical therapy plus curette and stripping wire method in treating diabetic foot. The other 18 patients were named as the control group who were treated by medical treatment and routine treatment. The granulation tissue maturity, wound healing, and the differences on curative effect were compared. Results 10 cases′wound granulation tissue maturity in the experimental group got++and+++on the 10th day while 4 cases in control group. Wound healing rate of the experimental group at the 10th and 14th day were (78.6±10.5)%and (82.7±8.4)%while the control group were (43.2±8.7)%and (66.2±10.1)%. Cure rate of the experimental group was 14/18 four weeks after treatment, the inefficiency was 0, while the control group was 6/18 and 3/18. Conclusions Curette and stripping wire method is a good method to promote the dressing diabetic foot wound healing. It is superior to traditional methods, worthy of clinical application.

Objective To investigate the value of genotype detection for diagnosis of hepatitis B virus (HBV ) infection . Methods 433 HBV pattients from January 2011 to August 2013 were detected by PCR-reverse dot blot hybridization ;the DNA were assaied by PCR ;the HBeAg were tested by ELISA .Results Of the 432 HBV patients ,the rato of genotypes B (68 .13% ) was significantly higher than that of genotypes BC (5 .77% ) and of genotypes C(26 .10% )(P<0 .05);there were no significiant differ-ence in the copy of the HBV DNA among the various genotype (P>0 .05);HBeAg negative rate of genotypes B (23 .82% ) ,geno-types BC(14 .78% ) ,genotypes C(1 .42% )had statistically significant(P<0 .05);Genes associated with disease severity :the ratio of genotype B for patients with mild-to-moderate hepatitis B was 87 .20% ,the rato of genotype C was 9 .34% and genotype BC was 3 .46% ,while the ratio of genotype C was 77 .08% ,genotype BC was 14 .58% ,genotype B was 8 .33% in severe hepatitis B .Con-clusion The genotype of HBV is related to disease severity and the negative rate of HBeAg ,it is not associated with HBV DNA of HBV .

BACKGROUND:Al oying is a convenient and effective method to alter the microstructure and control the corrosion behavior of magnesium al oy.
OBJECTIVE:To explore the in vitro and in vivo degradation of Mg-Nd-Zn-Zr al oy as a degradable medical biomaterial.
METHODS:(1) In vitro static immersion test:The immersion tests were carried out at (37.0±0.5) thermostatic bath. Six Mg-Nd-Zn-Zr al oy samples and six pure magnesium samples were immersed in the 250 mL simulated body fluid and vibrated without agitation during immersion. After 3, 7 and 30 days static immersion, the samples were taken out from the simulated body fluid. Then the in vitro corrosion properties were evaluated using scanning electron microscope and energy dispersive spectrometer analysis. (2) In vivo animal experiment:After bone tunnel was established in the left femur of adult New Zealand rabbits, the Mg-Nd-Zn-Zr al oy rods were embedded in the Mg-Nd-Zn-Zr al oy group, titanium al oy rods were embedded in the titanium al oy group, and only bone tunnel was established in the sham-operated group. At 1, 2, 4, 8 weeks after implantation, an X-ray of the implanted region was taken to determine the location and the degradation behavior℃in a of Mg-Nd-Zn-Zr al oy. At 4, 8 weeks after implantation, the corrosion product and its element composition were observed using scanning electron microscope with an energy dispersive spectroscopy system.

BACKGROUND:Thoracic vertebra connected to the corresponding section of the ribs constitute thoracic vertebral, which is deep, and the structure is complicated, so it is difficult to ful y expose thoracic vertebrae. Usual y, corresponding ribs is removed, and the injured site wil be reached through thoracic cavity. The trauma is big. Some complications often occur such as chest pain, and local skin numbness. Therefore, whether it is possible to reach the same target without removal of ribs through intercostal space became a new clinical problem. OBJECTIVE:To explore the safety and efficacy of autologous iliac bone graft and plate fixation for tuberculosis of thoracic vertebra. METHODS:A total of 30 patients diagnosed with tuberculosis of thoracic vertebra from January 2008 to December 2013 were conventional y treated with anti-tuberculosis treatment for 2 to 3 weeks, and then treated with autologous iliac bone fusion through intercostal space and anterior plate fixation. Postoperative fol ow-up was conducted from 6 to 22 months. Fracture healing condition, the degree of pain relief, Cobb angle change, length of incision, blood loss, operation time, postoperative recovery of neurological function were observed. RESULTS AND CONCLUSION:In 30 patients, the length of incision was (12.4±1.8) cm;longitudinal incision distraction width was (10±3.2) cm;the time of opening the chest was (16.0±2 .5) minutes;the time of closing the chest was (12.0±1.5) minutes;intraoperative blood loss amount was (430.0±87.4) mL. Preoperative and postoperative average kyphosis angles were respectively 27° and 8°, with an average rectification of 19°. The pain basical y relieved at 1 to 2 weeks after the surgery. 28 patients were healed, and the symptoms of 2 patients were improved. Postoperative fol ow-up radiographs revealed that autologous bone grafts were thoroughly fused, and the fusion time lasted from 4 to 5 months. These data verified that autologous iliac bone graft through intercostal space and plate fixation is an effective, safe method for tuberculosis of thoracic vertebra. The exposed range through intercostal space can satisfy the operation requirements of complete tuberculosis clearance, autologous iliac bone graft and plate fixation, and can ensure the integrity of the whole thorax and spine stability.
