Objective To compare the value of arthroscopic assisted percutaneous internal fixation and open reduction and internal fixation in treatment of tibial plateau fracture.Methods The clinical data of 180 patients of tibial plateau fracture were analyzed retrospectively,including 112 patients of type Ⅱ fracture (group A) and 68 patients of type Ⅲ fracture (group B).The patients in group A and group B were divided into group A1 (56 patients),A2 (56 patients),B 1 (34 patients),B2 (34 patients) respectively according to the odd number and even number of admission date.The patients in group A1 and B1 received open reduction and internal fixation and the patients in group A2 and B2 received arthroscopic assisted percutaneous internal fixation.The postoperative functional recovery was compared and evaluated between the same type of tibial plateau fractures under different treatments.Results In group A1:the postoperative functional recovery,the excellent was 12 patients,the good was 26 patients,the middle good was 12 patients,the bad was 6 patients.The rate of the excellent and the good was 67.9% (38/56).In group A2:the postoperative functional recovery,the excellent was 19 patients,the good was 34 patients,the middle good was 3 patients.The rate of the excellent and the good was 94.6%(53/56).The rate of the excellent and the good between group A1 and group A2 had significant difference (P < 0.01).After operation for 6 months,the HSS scores of knee joint and degree of flex and extend in group A1 and A2 had significant difference [(73.21 ± 8.32) scores vs.(85.58 ±9.89) scores,(35.6 ±6.6)° vs.(55.1 ±8.8)°] (P <0.01).In group B1:the postoperative functional recovery,the excellent was 8 patients,the good was 16 patients,the middle good was 7 patients,the bad was 3 patiens.The rate of the excellent and the good was 70.6%(24/34).In group B2:the postoperative functional recovery,the excellent was 12 patients,the good was 21 patients,the middle good was 1 patient.The rate of the excellent and the good was 97.1%(33/34).The rate of the excellent and the good between group B1 and group B2 had significant difference(P < 0.01).After operation for 6 months,the HSS scores of knee joint and degree of flex and extend in group B1 and B2 had significant difference [(75.32 ± 7.99) scores vs.(86.41 ±10.21) scores,(33.9 ±7.2)° vs.(56.6 ± 10.5)°](P<0.01).Conclusions The efficacy of arthroscopic assisted percutaneous internal fixation is better than open reduction and internal fixation either in type Ⅱ fracture or in type Ⅲ fracture.This method is mini-invasive and is worthy to spread.

Objective To explore the relationship of spinal tumors and endocrine gland-derived vascular endothelial growth factor( EG-VEGF) .Methods 77 cases of spinal tumors and 17 cases of vertebral compression fractures were collected.The testing group were grouped according to the pathological type of spinal tumor,the observ-ing group was consisted of vertebral compression fracture cases.The samples of various types of tumors in patients were collected during operation and the positive rate and expression of EG-VEGF mRNA were detected by RT-PCR technique,and the results of each group were statistical analysed.Results The results of relative expression of EG-VEGF mRNA in the unknown primary spinal metastases group,osteosarcoma group and chordoma group were higher, there were no statistically significant difference compared between three groups(all P>0.05).Relative expressions of that in osteoid osteoma group and giant cell tumor group were lower,so was in the observation group,there were no sig-nificant differences in three groups ( all P>0.05);The relative expressions of EG-VEGF mRNA in CUP group, osteosarcoma group and chordoma group were significantly higher than the osteoid osteoma group,with statistical sig-nificance[(0.81 ±0.21),(0.84 ±0.22),(0.79 ±0.41)vs(0.53 ±0.19),t=0.86,0.82,0.81,all P<0.05]. Similar results were also found in EG -VEGF mRNA positive expression rate in three groups.Conclusion EG-VEGF in normal spine spinal vertebrae and primary benign tumor ( osteoid osteoma,giant cell tumor) showed lower expression,which consistent with its tissue specificity,but in primary malignant spinal cancer ( osteosarcoma, chordoma) and unknown primary tumor spinal metastases showed the higher expression, indicating that it may be a measure of an important indicator of spinal cancer, and may play a key role in early diagnosis and treatment of cancer of the spine in the future.

OBJECTIVE To analyze the pathogen distribution and resistance pattern of the positive clinical sputum specimens in our hospital.METHODS The bacteria and fungi were identified by API system.The susceptibility of antimicrobial and antifungal agents was tested by KB and Rosco disk diffusion method and the data were analyzed by WHONET 5.4 software.RESULTS In 2008,in our hospital,the majority of the positive specimens were distributed among cerebral surgery department,intensive care unit(ICU),respiratory and pediatric departments.The pathogens of the eight highest isolating rate were Pseudomonas aeruginosa(20%),Candida albicans(18%),Acinetobacter baumannii(10.7%),Staphylococcus aureus(6.5%),Klebsiella pneumoniae(6%),Enterobacter cloacae(4%),Haemophilus influenzae(3.8%),and Stenotropho maltophilia(3.5%).In view of the resistance,no Staphylococcus species were resistant to vancomycin,but they were resistant to many other antimicrobial agents.Gram-negative Enterobactericaeae were sensitive to carbapenems,cefoperazone/sulbactam and piperacillin/tazobactam.Among nonfermenters,P.aeruginosa and S.maltophilia were resistant to the most antimicrobial agents while Acinetobacter were comparatively sensitive to carbapenems and cefoperazone/sulbactam.CONCLUSIONS The pathogens in lower respiratory tract infections have a high resistance rate to many antimicrobial agents.In view of the seriousness of this problem,we should emphasis on it and select antimicrobial agents rationally.

Clinical data of 655 patients with acute ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) in Luoyang Central Hospital during January 2017 to March 2020 were analyzed retrospectively. There were 425 cases who first visited PCI-capable hospital (PCI hospital group) and 230 cases who were transferred to PCI-capable hospital (transfer group). Compared with PCI hospital group, STEMI patients in the transfer group had a shorter first diagnosis time [2.0 (0.8, 4.2)h vs. 2.5(1.2, 4.1)h, Z=3.66, P<0.01], longer time from first medical contact to the balloon through (FMC2B) [175 (113, 344) min vs. 75 (57, 112) min, Z=-8.92, P<0.01], longer total ischemic time [5.4 (3.5, 9.8) h vs. 3.9 (2.4, 6.0) h, Z=-5.43, P<0.01]. There was no significant difference in the time from PCI hospital entry to balloon passage (DTB) between the two groups [43(29, 103) min vs. 46 (61, 94) min, Z=-0.56, P=0.573]. The compliance rate of FMC2B time<120 min in the transfer group was only 25.9% (50/193). However, the different first-visit hospital had no significant effect on the risk of heart failure ( OR=0.54, 95 %CI:0.16-1.79, P=0.311) and risk of death ( OR=1.14, 95 %CI:0.20-6.36, P=0.885). The results suggest that STEMI patients referred to PCI hospitals have considerable time delay, and the rate of compliance with FMC2B time<120 min is low.
