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.

Objective To study the natural history of mild cognitive impairment (MCI) progress to dementia and to evaluate the efficacy of acetylcholinesterase inhibitor (AChEI) donepezil on MCI.Methods Ninty-eight patients with MCI including amnestic MCI and non-amnestic MCI were retrospectively analyzed. The patients with donepezil or not were separately divided to two groups while they were matched by sex, age,degree of MCI and possession of the ApoE?4 allele.The rate of conversion from MCI to dementia, measured with the Mini-Mental State Examination (MMSE),Alzheimer's Disease Assessment Scale- Cognitive section(ADAS-Cog) and Wechsler Memory Scale-Revised (WMS-R),was compared between the two groups.Results In aMCI group,the rate of conversion dropped by 15.1% and 8.3% (P0.05).Conclusion Donepezil could postpone the conversion of MCI to dementia.

AIM: To understand the epidemiology and related factors of strabismic amblyopia of students of primary school, and to provide guidances for the prevention and control strategy.
METHODS: A total of 600 cases of primary school students of Leshan City, Jiajiang County were given vision, oblique incidence and ocular and other screening. The prevalence rate of poor eyesight of strabismus, amblyopia prevalence rate of different sexes, ages were compared, and the degree of amblyopia and strabismus of children with different types of amblyopia and whether or not had stereoscopic vision were counted.
RESULTS: The prevalence rate of amblyopia and strabismus prevalence rate were respectively 4. 0% and 2.5%;With the growth of all age, low vision of students was significantly decreased, the difference of comparison of low vision rate of each age had statistical significance (P<0. 05), but different ages, strabismus prevalence of different sexes, amblyopia prevalence were compared, the difference had no significant differences ( P>0. 05 );Ametropic amblyopia was the main type, accounting for 55. 6%, and the degree of amblyopia mainly was light, moderate; ametropic amblyopia, most of ametropic amblyopia and strabismus had stereo vision, but there were no stereopsis of most of the strabismic amblyopia and all esotropia.
CONCLUSION:Ametropic is mainly type of amblyopia, the prevalence of relationship between the incidence of strabismic amblyopia of primary school students and sexes is not obvious, but the oblique amblyopia treatment effect, such as the establishment of stereoscopic vision and the age, eye position has a close relationship, should be early discovered, early treatment.

This study introduced the clinical experience of Professor PAN Liqun in the treatment of plasma cell mastitis. Professor PAN believes that the treatment should take the understanding of the pathological anatomy as the precondition,take patients'pathogenesis as the basis and combine their menstrual cycles,then expel the toxin through tuofa.At the same time, external therapy should be applied in the treatment,especially the drainage through a small incision following the direction of the breast lesion,which can avoid the massive damage of patients'breast structure particularly the breast ducts,minimize the breast damage and maintain the physical integrity of the breast.Professor PAN's treatment fully plays the academic advantages of the combination of internal and external treatment of traditional Chinese medicine.

The simple and effective controlled needle devices were provided for acupuncture clinical trial so that the double blind acupuncture trial could be conducted possibly. The basic structure of filiform needle was modified. The needle handle was designed as hollow, the upper 1/3 of needle body as hollow and the lower 2/3 part as solid. The upper and lower parts were linked with an elastic unit. At the same time, the needle pad was attached. With this method, the new sham-acupuncture device was designed and developed. The new sham-acupuncture device could simulate needle insertion, manipulation and the techniques of reinforcing and reducing, without inserting into the human body. This innovation lays the foundation for perfecting the clinical randomized controlled blind trial of acupuncture.

Objective To explore the effect of endoplasmic reticulum stress (ER stress) in uric acid?induced phenotypic change in renal tubular epithelial cells (HK?2). Methods (1) HK?2 cells were cultured with 0, 75, 150, 225, 300 mg/L uric acid for 24 h in vitro. (2) The cells were divided into normal control group, ER stress inhibitor 4?PBA (5 μmol/L) group, uric acid (150 mg/L) group and 4?PBA+uric acid group for 24 h. Morphological changes of HK?2 cells were observed under inverted microscope. MTT assay was used to detect the proliferation of HK?2 cells treated with 150 mg/L uric acid for 24, 48 and 72 h. The protein expressions of α?smooth muscle actin (α?SMA), vimentin, snail, glucose regulated protein 78 (GRP78) and the phosphorylation of eukaryotic initiation factor 2α(p?eIF2α) in HK?2 cells were measured by Western blotting. Results Compared with the control group, HK?2 cells in uric acid groups (150, 225, 300 mg/L) showed fibroblast?like appearance. The protein expressions of α?SMA, vimentin, snail, GRP78 and p?eIF2α in 150 mg/L and 225 mg/L uric acid groups were higher than those in the control group (all P<0.05). The proliferation of HK?2 cells in 150 mg/L uric acid group was lower than that in control group at 48 and 72 h (all P<0.01). Compared with the uric acid group, the cell morphology in 4?PBA+uric acid group was improved, and the protein expressions ofα?SMA, vimentin, snail, GRP78 and p?eIF2α were decreased (all P<0.05). Conclusions Uric acid may induce the phenotype transformation of renal tubular epithelial cell, and ER stress is involved. 4?PBA may inhibit the uric acid?induced ER stress response and phenotypic transformation, and may be beneficial in attenuating uric acid?induced renal tubular damage.

Objective To determine the correlation between high serum levels of homocysteine (Hcy), low folate and
vitamin B12 levels and the clinical index of neonatal hypoxic ischemic encephalopathy (HIE), providing the reference for the diagnosis and treatment of neonatal patients with HIE. Methods Totally 94 cases of neonatal patients with HIE (32 mild, 40 moderate, and 22 severe) treated by Tianjin children’s hospital from April 2010 to April 2011 were enrolled. The control group was 20 cases of neonatal patients with neonatal swallowing syndrome at the same period. The serum levels of Hcy, folate and vitamin B12 were compared between four groups. Results There were significant differences in serum levels of Hcy, folate and vitamin B12 between four groups (P<0.05). Compared with the control group, there was higher level of Hcy and lower levels of folate and vitamin B12 in HIE groups. The Hcy levels increased with the deterioration of HIE in three HIE groups. The serum level of vitamin B12 was significantly lower in severe group than that in moderate group (P<0.05). Conclusion The serum Hcy level has certain reference value in tassessment of the severity of HIE. The supplementation of folate and vitamin B12 may play an active role in the process of the treatment in neonatal patients with HIE.
