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.

CTN of tumor cells were 0.5677?0.3194 and 0.5726?0.2895, respectively,which were significantly lower than those of normal bladder mucosa ( P

Objective:To investigate the effect of EPO on humoral and cellular immunity and the monocyte antigen presenting function in patients with chronic renal failure(CRF).Methods:60 patients with CRF were divided into three groups.Group A patients accepted hemodialysis and treated with EPO.Group B patients treated with EPO and didn't accept hemodialysis.Group C patients didn't accept EPO treatment and hemodialysis.After 8 weeks treatment,the subpopulations of T lymphocyte were analyzed with detected by flow cytometry analysis method;Immunoglobulins were measured with radioactive immuntzation method.In addition,the infection rate of patients with CRF in every group was compared.Results:The parameters of immune functions of patients with CRF were comparable between groups before treatment.After treated with EPO for 8 weeks,RBC numbers and Hb were significantly increased in patients of group A and group B,but not in patients of group C.IgG and IgA were increased in patients of groups A and groups B and have statistic differences as compared with that in patients of group C(P

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.

Objective To study the characteristics of liver injury induced by simvastatin combined with HRZ (Isoniazid,Rifampicin and Pyrazinamide) in SD rats.Methods Fifty-four 8-week-old SD rats were randomly divided into 3 groups:group A (control),group B (HRZ) and group C (simvastatin combined to HRZ),half of each group were male.We calculated the accurate dose respectively before those rats were given intragastrical administration of corresponding drugs.Six rats were killed in each group on 10th,20th and 40th day,respectively.Before this,blood was fastened from femoral of every rat that would be killed to test liver function,liver tissue slices were made in order to observe the pathological characteristic.Results Alanine amiotransferase of group C elevated in line with time and reached statistic difference on 40th day,furthermore,it was significantly higher than group A (P＜0.05).Total bilirubin and direct Bilirubin of group C were significantly higher than those of group A from the beginning to the end (P＜0.05),however,they declined rapidly on 10th day,this trend also had statistic difference (P＜0.05) At the end of this experiment,hepatic cords was disordered slightly,but swelling liver cells and vacuolar degeneration were observed,the nuleus of cell condensed.Soakage of monocytes,neutrophils,and lymphocytes occurred in the portal and lobule regions,or even spotty necrosis occasionally.Conclusion Cholestasis occurs at the early stage when simvastatin is combined with HRZ in SD rats,however,it has a rapidly degressive trend.In contrast,Alanine amiotransferase elevates,furthermore,pathological injury or even spotty necrosis can emerge in liver tissue slices.

Objective To investigate the effect of microbubble-enhanced non-focused ultrasound on liver uhrastructure during the treatment of hepatic trauma.Methods The model of hepatic trauma was established in 18 healthy New Zealand rabbits.The subjects were divided into trauma group,ultrasound group and ultrasound-microbubble group according to the random number table,with 6 rabbits each.Thicker region of the left hepatic lobe was treated by custom-made non-focused ultrasound for 5 min.Peak intensity (PI) was used to evaluate the blood reperfusion of the target region after treatment.Liver specimens were performed transmission electron microscope examination immediately and 24 h after treatment to analyze ultrastructure changes.Results PI ratio in ultrasound-microbubble group (15.1 ± 2.6) was significantly lower than that in trauma group (23.1 ± 1.1) and ultrasound group (23.4 ± 1.3) (P ＜ 0.05).But the difference between trauma and ultrasound groups was insignificant (P ＞ 0.05).Compared with trauma and ultrasound groups immediately after treatment,hepatic cells in ultrasoundmicrobubble group had obvious edema,sinusoids thinned,organelles arranged in disorder,mitochondrial edema was present,endothelia cells of interlobular hepatic artery,interlobular vein and bile canaliculi in the portal area damaged,and microvilli of bile canaliculi disappeared.Hepatic cells showed morphology of apoptosis 24 h after treatment.Conclusion Microbubble-enhanced non-focused ultrasound can be used to make rapid hemostasis by decreasing the blood perfusion,but it causes certain damage to the ultrastructure of hepatic cells and may induce apoptosis in the radiation zone and neighboring cells.

The individual variability should be considered in precision medicine-prevention and treatment strategies.Medical research using genomics, proteomics, metabolomics, systems analyses, and other modern tools has made big progress.In 2002, the members of the Complex-Trait Consortium proposed to develop a new mouse genetics resource called the Collaborative Cross (CC).The CC is a genetic reference panel of recombinant inbred lines of mice, designed for the dissection of complex traits and gene networks.It will provide a powerful measure for functional studies of biological networks, which will be essential to understand the intricacies of disease processes.

OBJECTIVE:To discuss the effect of early usage with Wulingjun powder on the behavior of rats with post-traumat-ic stress disorder(PTSD)and the level of interleukin-1β(IL-1β)and IL-6 in their hippocampi. METHODS:50 SD rats were ran-domized into control group(normal saline),model group(normal saline),positive control group(paroxetine,10 mg/kg)and the groups of low and high-dose(0.4,0.8 g/kg)Wulingjun powder. The rats in all groups except for control group,were exposed to single prolonged stress for the establishment of PTSD models. Corresponding drugs were given ig immediately after such establish-ment,qd,for 7 consecutive days. An open field test(the times of the rats’entering the central area and the percentage of the time the rats spent in exploring the central area within 10 min were recorded)was conducted 7 days after giving drugs;and an elevated plus-maze test(the times of the rats’in opening arms and the percentage of the time the rats spent in opening arms within 5 min were recorded)was carried out 8 days thereafter,to observe the behavior of the rats. Then the rats were sacrificed to determine the level of IL-1β and IL-6 in their hippocampi by ELISA. RESULTS:Compared to the normal group,the behavioral index of the rats in model group was significantly lower,and the level of IL-1β and IL-6 in their hippocampi was significantly higher(P<0.05 or P<0.01). Compared to model group,the behavioral index of the rats in positive control group and the group of high-dose Wuling-jun powder was significantly higher,and the level of IL-1β and IL-6 in their hippocampi was significantly lower (P<0.05),but no statistically significant difference was shown in all indexes in the group of low-dose Wulingjun powder (P>0.05). CONCLU-SIONS:High-dose Wulingjun power can improve the anxiety-like behavior of the rats with PTSD,which may be related to the re-duction in the level of IL-1βand IL-6 in the hippocampus.
