BACKGROUND:Adipose-derived mesenchymal stem cels have rich sources that are easily obtained, which can be used to treat acute myocardial infarction. OBJECTIVE: To investigate the therapeutic effect of adipose-derived mesenchymal stem cel transplantation on acute myocardial infarction in rats. METHODS:Rat models of acute myocardial infarction were made and subjected to adipose-derived mesenchymal stem cel transplantation in comparison with model and control (sham operation) groups. RESULTS AND CONCLUSION:Echocardiography findings showed significant improvement in the left ventricular end-systolic diameter, left ventricular end-diastolic diameter and ejection fraction in the cel transplantation group compared with the model group (P < 0.05). Hematoxylin-eosin staining showed that myocardial infarction was evident in the model group, in which, there were rarely viable myocardial tissues and few vessels in the infarcted region, but in the cel transplantation group, there were evident survived myocardial tissues and transplanted cels. The percentage of infarct size was significantly lower in the cel transplantation group than the model group (P < 0.05). Immunohistochemical staining showed that adipose-derived mesenchymal stem cels were able to survive in the infarcted myocardial tissues, and the expression of cardiac troponin T in the cel transplantation group was significantly higher than that in the model group (P < 0.05). Experimental data show that adipose-derived mesenchymal stem cel transplantation can protect the myocardial tissues after myocardial infarction, and effectively improve the myocardial function.

Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

AIM: To explore the long-term efficacy of Q-factor guided laser epithelial keratomleusis ( LASEK ) for myopia and astigmatism with positive Q-factor.
METHODS: There were 158 eyes which were myopia and astigmatism with positive Q- factor taken in two groups randomly: 86 eyes accepted Q - factor guided LASEK as observation group and 72 eyes accepted routine LASEK as control group. The difference between the two groups about all data was similar. The uncorrected visual acuity ( UCVA ) and the best corrected visual acuity ( BCVA ) as well as diopter, ocular tension, corneal topography, Keratometry value K, aspherical factor Q, Higher-order aberrations ( HOA ) , corneal thickness by ultrasound and, contrast sensitivity ( CS ) , Haze were examined and compared before and after surgery. All the cased were followed up for 14d, 1, 3, 6, 12mo. And there were no statistical difference among the data before surgery.
RESULTS: After 12mo there were no statistical difference between the two groups about UCVA and BCVA. But the safety index of observation group was 1.10, that of control group was 1. 07. The validity index of observation group was 1. 06, that of control group was 0.99. The HOA of observation group was 0. 45±0. 17μm, and that of control group was 0. 72±0.25μm, there was statistically significant difference (t=-8. 193,P=0. 000). Q factor of observation group was 0. 41±0. 17, that of control group was 0. 77±0. 22, there was significant difference (t=11. 377,P = 0. 028). The contrast sensitivity of 3mo post surgery of patients in the observation group returned to the level of before surgery. But in the control group the contrast sensitivity of the patients did not returned until 6mo.
CONCLUSION:Q-factor guided LASEK for myopia and astigmatism with positive Q-factor is stable, safe and effective. The operation allow for reducing the high order aberrations, maintaining the most asphericity of cornea, saving more in corneal tissue, which cause faster recovery of contrast sensitivity, less haze and better visual quality.

AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma.
METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma.
RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them,
the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%).
CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

Objective:To identify the cerebral activation patterns associated with the processes that occur during viewing Chinese and English words in native Chinese English learners.Methods:12 right-handed Chinese English hamers were divided into two groups equally,namely English majors and non-English majors,and took semantic judgement tasks of both English and Chinese words,for whom the fMRI images were coUected.Results:To various degrees,all subjects demonstrated activation of associated cerebral regions in both hemispheres and the left hemisphere activation was more significant for most subjects.Except for elassieal regions involved in language processing,such as Wemicke areas and Broca areas,there were other activated cerebral regions,including cerebellum,limbic system and basal ganglia nucleus,etc.To sum up,there were apparent overlap for cerebral activation distribution and no specific processing areas for both tasks.The analysis of ROI(region of interest)suggested that subjects in specialized group were more dependent on right hemisphere to perform English words task.Conclus/on:Language cognition is dominated by left hemisphere,which is also shared by the right hemisphere to various degrees and thus two hemispheres work by ways of both dissociation and coordination.It is possible that working strategy of the right hemisphere in English task is related to proficiency of the second language.A variety of distinctions are shared by each subject for language cognitive patterns.
