BACKGROUND:Ilizarov technique is an effective treatment method which can solve various complications that occurred in the process of treatment, especial y for the treatment of nonunion associated with soft tissue defects or severe infection. OBJECTIVE:To review the research progress of nonunion treatment with the Ilizarov technique. METHODS:A computer-based search was performed on the CNKI database and PubMed database from January 1992 to April 2013 for the articles related to the Ilizarov technology for the treatment of nonunion. The key words of“nonunion, external fixator, Ilizarov”in English and“nonunion, fracture nonunion, external fixation, Ilizarov”in Chinese were used to search the articles in the title and the abstract. Final y, a total of 37 articles were included to review. RESULTS AND CONCLUSION:Ilizarov technique is an effective method to treat limbs nonunion with the infection and severe bone defect. It has become an international y recognized gold standard. Due to the firmly fixation of the Ilizarov ring external fixator, it can not only eliminate the shear force and rotation stress, thus playing a role of stretch tension and compression, but also has the cyclical micro-axialmotion characteristic during weight-bearing walking which can better promote bone union. Based on the reviews of the research progress of Ilizarov technique in the treatment of nonunion in recent years, we further investigate the advantages and methods of Ilizarov technique in the treatment of limbs nonunion. The clinical application of the method should fol ow the individual principle, and then choose the best and suitable method based on the analysis of advantages and disadvantages about the patient’s condition.

Objective:To compare the effect of fluorescence staining and periodic acid-Schiff staining in the diagnosis of fungal keratitis (FK).Methods:A total of 147 corneal specimens from 147 FK patients treated in Eye Hospital of Shandong First Medical University from January 2017 to May 2019 with positive corneal scraping or fungal culture were collected.Among them, there were 84 cases with penetrating keratoplasty (PKP), 42 cases with lamellar keratoplasty (LKP) and 21 cases with lesion resection.Another 11 cases with herpes simplex virus keratitis served as negative control.The corneal tissue specimens were performed with fungal fluorescence staining and periodic acid-Schiff staining, respectively.The stained sections were placed under fluorescence microscope and optical microscope to observe fungal hyphae or spores, respectively.The positive rates of the two staining methods were compared, and the positive cases of the diagnosis of FK in corneal tissue samples obtained by different surgical methods and corneal infection caused by different strains of the two staining methods were compared.Written informed consent was obtained from each patient.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Shandong Eye Hospital (No.SDSYKYY-2016012).Results:The positive rate of periodic acid-Schiff staining and fungal fluorescence staining was 60.5% (89/147) and 79.6% (117/147), respectively.The positive rate of fluorescence staining in the diagnosis of fungal keratitis was significantly higher than that of periodic acid-Schiff staining ( χ2=28.00, P<0.01), and both the specificity of the two staining methods was 100%.The positive rate of specimens obtained by PKP with fluorescent staining was 85.7% (72/84), and the positive rate with periodic acid-Schiff staining was 65.5% (55/84), and the difference was statistically significant ( χ2=17.00, P<0.01). The positive rate of specimens obtained by LKP with fluorescent staining was 71.4% (30/42), and the positive rate with periodic acid-Schiff staining was 52.4% (22/42), and the difference was statistically significant ( χ2=8.00, P<0.01). The positive rate of resected foci specimens with fluorescent staining was 71.4% (15/21), and the positive rate with periodic acid-Schiff staining was 57.1% (12/21), and the difference was not statistically significant ( χ2=1.30, P=0.25). The positive cases of two kinds of staining were different among different fungal strains.Among them, the positive cases of Fusarium solani complex, Pythium insidiosum, Aspergillus fumigatus complex, Candida guilliermondii, Trichoderma and Nigrograna mackinnonii with fluorescence staining were 19, 5, 5, 1, 1 and 1, and the positive cases of periodic acid-Schiff staining were 11, 0, 3, 0, 0 and 0, respectively.The staining results of the 11 negative controls were negative. Conclusions:Fluorescence staining is more sensitive than periodic acid-Schiff staining in the detection of fungal components in paraffin-embedded corneal tissues, and it can significantly improve the fungal detection rates.

Traditional Chinese medicine has a long history of intranasal administration. Compared with the other administration routes, intranasal administration has the benefits of fast absorption, high bioavailability, high brain-targeting and non-invasive. In the past few years we take "Xingnaojing" and "Tongqiao Sanyu formula" as model drug and studied pharmacokinetics of effective components of different polarities. MDCK/MDCK-MDR1 cells were used to simulate blood brain barrier to study the permeate behaviors of different drug and the mechanism of enhancing effects of aromatic medicine. Then a microemulsion (modified by mPEG2000-PLA) was prepared for intranasal administration, and the pharmacokinetics and investigated tissue distribution were studied by fluorescence imaging. The irritation of the drug and different preparations were studied on human nasal epithelial cell (HNEC) cell and living animals. In this paper, we reviewed the achievements and hope that it can provide constructive suggestions for the future research.
