Recently,the progress in employing transplanting stem cells to cure injured retina is very fast and has been continuously yielding exciting results.Various sources are used in the studies,including retina-derived cells such as M?ller cells and ciliary body cells,and non-retina-derived cells such as embryonic stem cells and brain-derived stem cells.This review briefly discusses the recent progress of these studies.

Hemorrhoid refers to soft vein mass formed by varicosity of submucosal veins around the end of the rectum and subcutanceous veins of the anal canal. It is the most common anorectal disease. This article summarized the regular patterns, features and advantages of Professor Yu Hai-Bo's acupuncture-moxibustion therapy for hemorrhoids, in order to guide the acupuncture treatment for hemorrhoids.

Objective To study the efficacy of intravitreous injection (IVI) or sub-Tenaninfusion (STi) of triamcinolone acetonide (TA) for diabetic macular oedema. Design Retrospective cases series. Participants 37 cases (37 eyes) with diabetic macular oedema confirmed by fundus fluorescence angiography (FFA) and optical coherence tomography (OCT). Methods Patients were received 4mg TA by single intravitreous injection or 40mg TA by three times sub-Tenoninfusion at 0d, 2w, 4w. The best corrected visual acuity, fundus examination, intraocular pressure, fundus fluorescence angiography were further analyzed, and the retinal thickness of macular fovea were measured by OCT. Main Outcome Measures The visual acuity, thickness of retinal macular fovea, ocular pressure was measured. Results 32 cases (32 eyes) completed the 24 week followed-up. In group IVI, the visual acuity before and after injection was 0.10±0. 03, 0.24±0.06(F=15.459, P=0.000) respectively; and retinal thickness of macular fovea is(460.73±46.33)μm,(394.53±41.43)μm (F=25. 282, P=0.0000) respectively. But in group STi, the visual acuity before and after injection is 0.11±0.04, 0.18±0.07(F=6.989, P=0.000) accordingly; and retinal thickness of maculur fovea is (454.76±56.28)μm,(424.94±42.69)μm (F=5.145, P=0.000) respectively. There was obvious statistical significance between two methods at same time point(all P<0.05). The serious, irreversible complications had not been found in all patients during follow-up. Conclusion Triamcinolone acetonide by single intravitreous injection or repeatedly sub-Tenoninfasion are good ways to relieve diabetic macular oederna, IVA-TA is more effective, and STi-TA safer.

To explore the associations between the presence of bacteria and virus in the nasopharyngeal secretions, and wheezing, condition and hospitalization period in infants with community acquired pneumonia. Methods Clinical data, inclu-ding detection of bacteria and viruses, conditions and hospitalization period, of 1106 hospitalized infants with community ac-quired pneumonia from March 2009 to February 2010 were retrospectively analyzed. The infants were classiifed into wheezing (697 cases) and non-wheezing (409 cases) groups. Results Viruses were detected in 540 infants (48.8%), and the total detection rate of viruses and detection rate of respiratory syncytial virus in wheezing group were signiifcantly higher than those of non-wheezing group (P=0.000). Bacteria were detected in 590 cases (53.3%) and no signiifcance was found between two groups (P=0.821). The detection rate of Streptococcus pneumonia was higher in wheezing group than that of non-wheezing group (P=0.038). Comparing to the infants detected with both viruses and bacteria, no signiifcances were found in the occurrence of severe pneumonia and hos-pitalization period in those infants detected with viruses only (P>0.05), as well as in the wheezing time of period (P>0.05). Con-clusions Wheezing in infants with community acquired pneumonia is related to the infection of viruses, especially to respiratory syncytial viruses. Virus infection accompanying bacterial infection has no impact on duration of hospitalization and wheezing. The infection of Streptococcus pneumonia may relate to wheezing in infants.

This is to report the study of degradation of earthworm extracts prepared by wet superfine grinding in simulated gastrointestinal environment. Enzymatic reactions were terminated by adjusting the solution pH or using membrane bioreactor principle. Earthworm protein concentration change was detected by Bradford method, the degraded state of protein was described with SDS-PAGE technology, and the degraded state of small molecule substances was detected by HPLC. The results showed that earthworm protein degraded completely in artificial gastric juice. High molecular weight protein degraded greatly in artificial intestinal fluid, while low molecular weight protein was not significantly degraded. Small molecular substances degradation did not degrade in artificial gastric juice, while they degraded obviously in artificial intestinal fluid, there is even new small molecule substance appeared. Finally it is concluded that the substance that having therapeutic effects in vivo may be some degraded peptide, amino acid and stable small molecules existed in artificial intestinal fluid.

The effects of continuous subcutaneous insulin injection (CSII, n=306) and multiple subcutaneous insulin injection (MSII, n=310)on hyperglycemia in patients with diabetes mellitus were compared. The results suggest that the effect of CSII is more prompt and efficient with lower incidence of hypoglycemia as compared with MSII.

AIM To investigate whether pretreatment with prostaglandin E 1 (PGE 1) might protect myocardium against peroxidative injury in early phase and in delayed phase. METHODS Rats were pretreated with PGE 1 (25 or 150 mg?kg -1 ). Isoproterenol (ISOP)(80 mg?kg -1 ) were injected peritoneally (ip) to induce acute myocardial infarction 20 minutes (early phase) or 24 hours (delayed phase) after pretreatment. Hearts were removed punctually 24 hours after ip ISOP and were assayed for content of malonaldehyde (MDA), activity of glutathione peroxidase (GSH Px) and superoxide dismutase (SOD). RESULTS ISOP caused myocardial injury with increased MDA content and SOD activity, and decreased GSH Px activity. Pretreatment with PGE 1, at each dose and in both phase, decreased the MDA content ( P
