China Medical Equipment 2015;(7):68-70,71
Objective:To investigate the clinical effects of transcranial ultrasound to arterial recanalization in acute ischemic stroke patients.Methods: Eighty cases of patients with acute ischemic stroke from February 2010 to May 2013 in our hospital were chosen as the experimental objects, and were divided into experimental group and control group randomly. The control group were treated with urokinase and transcranial ultrasound, the experimental group were treated with urokinase and placebo. The clinical effects of each group were compared.Results: The experimental group in the 2h and 24h when the recanalization rate was obviously higher than the control group, and the difference is statistically significant(x2=8.916,x2=8.155,P<0.05). Symptoms improved rate of patients in the 2h and 24h in the experimental group was obviously higher than that of the control group, and the difference was statistically significant. The experimental group prognostic good rate was 56.09%, while the control group was 23.08%, the difference was statistically significant(x2=9.081,P<0.05). The two groups had no statistically significant difference in mortality(x2=0.005,P<0.05). Conclusion: Patients with acute ischemic stroke with transcranial ultrasound treatment can significantly improve the prognosis of the patients condition, improve the rate of recanalization.

Journal of Third Military Medical University 2003;0(10):-
Objective To investigate the therapeutic effect of transplantation of limbal epithelial cells and decellularized porcine cornea construct in rabbits with corneal alkali burn.Methods Allogeneic rabbit limbal epithelial cells were cultured and identified.Porcine cornea scaffold was fabricated by decellularization.The LECs-DPC construct was cultured and transplanted to the alkali-burned corneal surface of rabbits(4month follow-up).Results Immunocytochemistry and RT-PCR analyses revealed the presence of ABCG2 positive limbal stem cells.A general view showed the corneas were clear and vessel-free postoperatively.HE and Masson Trichrome staining results indicated the epithelial stratification,fewer cellular infiltration,DPC' integration into host corneal tissues,and more regular collagen configuration.Transmission electron microscopy exhibited formation of desmosomes and microvilli.Conclusion Allogeneic limbal epithelial cells transplantation using DPC as a carrier can restore corneal clarity after alkali burn in a rabbit model.

Choroidal thickness and its relevance with retinal disease has been widely studied in recent years,as choroid is an important source of retina blood supply.Diabetic retinopathy (DR) studies have been focused on retinal vascular injury and related circulatory disorders for a long time,however recent studies have found that choroidal blood vessels are also affected by diabetes,including the thickness changes.The choroidal thickness of diabetic patients is thinner than normal.There is no conclusive conclusion about choroidal thickness and the severity of DR lesions,as the choroid thickness results are determined by multiple factors,including diseases,ocular conditions (choroidal vascular status,ocular axial length,refractory errors and other eye parameters),systemic factors (age and sex) and measurement methods.Therefore,it is necessary to calibrate the ocular and extra-ocular factors affecting choroidal thickness when trying to further clarify the relationship between the choroidal thickness and DR.

Objective To evaluate the value of ultrasonic elastography for diagnosis of chronic nonspecific low back pain. Methods From March to September, 2016, 32 patients diagnosed as chronic nonspecific low back pain and other 32 healthy people (controls) were measured lumbar erector spinae with ultrasonic elastography, and calculated Yang's modulus. The correlation between Yang's modulus and Visual Analogue Scale (VAS) or Japanese Orthopaedic Association (JOA) score in the patients were investigated with Pearson's analysis. Re-sults There was no significant difference in Yang's modulus between bilateral lumbar erector spinae in both the patients and the controls (t<1.849, P>0.05), but it was more in the patients than in the controls (t=9.931, P<0.001). The Yang's modulus was positively correlated with VAS score in the patients (r=0.614, P<0.001), but not with the JOA score (r=-0.243, P=0.180). Conclusion Ultrasonic elastography can be applied to differentiate low back pain from the healthy, and measure the intensity of pain.

During 131Ⅰ therapy or the natural course of DTC,2% to 5% of them will gradually no longer be sensitive to 131Ⅰ therapy and lead to radioactive iodine-refractory DTC (RAIR-DTC).Recent studies found that alterations of critical molecular targets in main signal transduction pathways could decrease the iodine-trapping function of thyroid carcinoma,such as BRAFV600E mutation,followed by negative 131 Ⅰ-whole body scan (WBS) and discounted efficacy.This article reviews novel diagnostic and therapeutic modalities for RAIR-DTC.

Objective To further identify the isolated Mycoplasma genitalium (Mg) from the high risk population of STD in China. Mothods The morphology of Mg standard strains and clinical isolates were observed under electron microscopy (EM) and atomic force microscopy (AFM). Mg sample preparation for AFM was fixed on mica and AFM images of scanning observation were captured by contacting and tapping modes and operated under normal atmospheric pressure and temperature. Results and Conclusion Mg had a diversity of shapes, including flask, pear, spindle or round shape with projecting neck portion and slightly broadened terminal structure under EM. The morphologic features under AFM were similar to those observed by EM. The typical Mg showed shapes of flask and pear with noticeable narrow ring or mark in the neck portion. The size of Mg measured under EM and AFM was similar as well. Mycoplasma

In artificial immune optimization algorithm, the mutation of immune cells has been considered as the key operator that determines the algorithm performance. Traditional immune optimization algorithms have used a single mutation operator, typically a Gaussian. Using a variety of mutation operators that can be combined during evolution to generate different probability density function could hold the potential for producing better solutions with less computational effort. In view of this, a linear combination mutation operator of Gaussian and Cauchy mutation is presented in this paper, and a novel clonal selection optimization method based on clonal selection principle is proposed also. The simulation results show the combining mutation strategy can obtain the same performance as the best of pure strategies or even better in some cases.
