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.

OBJECTIVETo analyze the efficacy and medication principles of Professor Xu Fu-songs traditional Chinese medicine (TCM) protocols for male diseases.

METHODSWe reviewed and descriptively analyzed the unpublished complete medical records of 100 male cases treated by Professor Xu Fu-song with his TCM protocols from 1978 to 1992.

RESULTSThe 100 cases involved 32 male diseases, most of which were difficult and complicated cases. The drug compliance was 95%. Each prescription was made up of 14 traditional Chinese drugs on average. The cure rate was 32% , and the effective rate was 85%. Professor Xu Fu-song advanced and proved some new theories and therapeutic methods.

CONCLUSIONProfessor Xu Fu-song's TCM protocols can be applied to a wide range of male diseases, mostly complicated, and are characterized by accurate differentiation of symptoms and signs, high drug compliance, and excellent therapeutic efficacy.

Objective To observe the effect of acupuncture at lumbar Jiaji (EX-B 2) points plus botulinum toxin injection on the seated function of patients with spastic cerebral palsy.Method Sixty patients aged 1-4 years old with spastic cerebral palsy were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at lumbar Jiaji (EX-B 2) points plus botulinum toxin injection, while the control group was by conventional acupuncture plus botulinum toxin injection. After 3 treatment courses, the seated function zone (zone B) of Gross Motor Function Measure (GMFM) was used for evaluation, and the clinical efficacies were compared.Result Respectively after 1, 2, and 3 treatment courses, the total effective rates were 46.7%, 73.3% and 83.3% in the treatment group, versus 33.3%, 46.7% and 60.0%. There were significant differences in comparing the total effective rate between the two groups after 2 and 3 courses (P<0.05). After the first treatment course, the seated function score of GMFM was significantly changed in both groups (P<0.01). After the second course, the seated function score was significantly different from that after the first course in both groups (P<0.01). After the third course, the seated function score was significantly different from that after the second course in both groups (P<0.01). There was a significant between-group difference in comparing the changes of the seated function score during the second treatment course (P<0.01). There was a significant between-group difference in comparing the changes of the seated function score during the second treatment course (P<0.05). Conclusion Acupuncture at lumbar Jiaji (EX-B 2) points plus botulinum toxin injection can produce a more significant efficacy in improving the seated function of patients with spastic cerebral palsy.

Objective To investigate the characteristics of thyroid surgical emergency related disease and prognosis,provide the basis to improve treatment.Methods Retrospective analysis of 24 cases of thyroid surgical emergency patients in Peking Union Medical College Hospital,Chinese Academy of Medical between 2004 and 2014who was performed,and the Fisher analytic method was used.Results According to the condition of diseases,conservative treatment for 1 case,surgical treatment for 23 cases,interventional therapy for 2 cases were performed.The overall preoperative diagnosis rate was 45.8％.The overall perioperative death were 5 cases (20.8％),total death were 7 cases(29.2％).8 cases preoperative diagnosed or highly suspected thyroid lymphoma patients were received oral or intravenous corticosteroid treatment,with the use of corticosteroids perioperative survival rate increased from 50％ to 100％.Conclusions (1) Thyroid surgical emergency with different causes should quickly make a clinical diagnosis based.on the patient's history and examination,select rational treatments.(2) Thyroid lymphoma patients that preoperative highly suspected or diagnosed,immediate received glucocorticoid treatment can reduce airway obstruction and decrease mortality,should be promoted.

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 observe whether the killing effect on HCC SMMC-7721 cell of the antihepatocellular carcinoma scFv reconstructed by pharmacy was enhanced or not.Methods Prokarycytic expression vector containing PET32a-RC-RNase was induced to express by IPTG.The inclusion body purified and Western-blotting was used.PC.CHOL and CHS was added in chloroform.Dry membrane was formed after chloroform was removed.RC-RNase protein solution was added to dissolute the membrane.Then pass the solution over a Sephadex G-50 column after ultrasound and filtrated to detect the encapsulation efficiency of the liposome.The solution reacted in EDC.SSNHS and MES for 30 minutes.Then add hdscFv to the solution in 4 ℃ over night.MTT method was used to detect the killing effect on HCC cell of immunoliposome RC-RNase,immunotoxin RC-RNase and liposome RC-RNase in vitro.Resuits The killing effect on HCC cell of immunoliposome RC-RNase is the best.but that of Iiposome RC-RNase is the worst.The respective JC50 are:3.28μg/ml,22.44μg/ml and 98.26μg/ml.Conclusion The anti-hepatocellular carcinoma scFv relomtructed by pharmacy can promote the killing effect on HCC cell and may have potential in the treatment of hepatocarcinoma.

Objective:To clone the RC-RNase gene and prepare its recombinant prokaryotic construct, and then to express RC-RNase protein using Escherichia coli system. Methods: RC-RNase cDNA was obtained by RT-PCR from liver of Rana catesbeiana, and cloned into pUCm-T plasmid for nucleotide sequencing. Its expression construct was prepared using the 6?His vector pRSET-A, and induced to express by IPTG in Escherichia coli BL21(DE3). Western blotting identified the expression product. Results: A 380 bp long cDNA was obtained from liver of Rana catesbeiana, restriction sites and sequence being consistent to those reported for RC-RNase. After introducing the gene into Escherichia coli and through the induction by IPTG, it was observed a new peptide at the expected position (Mr 16000) on SDS-PAGE gel. This product was proved to be the target protein via Western blotting. It existed in a form of inclusion body and its efficiency reached 12.5% of total bacterial proteins. Conclusion: RC-RNase gene was cloned and expressed in Escherichia coli. The protein could be used for characterizing the biological activities and function of RC-RNase.
