Background Marrow mesenchymal stem cells (MSCs) has been successful induced to differentiate into corneal cells,retinal ganglion cells (RGCs) and retinal neuron-like cells in recent years,but there are few studies about MSCs induced into photoreceptor cells and their microenvironment.Objective The aim of this study was to explore the induce and differentiation of bone marrow mesenchymal stem cells (BMSCs) into photoreceptor-like cells in vitro and microenvironment.Methods The second generation of human BMSCs strain and RPE cells strain were cultured and passaged,respectively,and the fourth generation of BMSCs and the third generation of RPE cells were used in the experiment.BMSCs were cocultured using the mesenchymal stem cells medium (MSCM) contained 20 μg/L basic fibroblast growth factor (bFGF),20 μg/L epithelial growth factor (EGF)and 20 μg/L brain derived neurotrophic factor (BDNF) with RPE cells to induce the differentiation of BMSCs in the induced group,and BMSCs were cultured in MSCM only in the control group.The morphology of induced and differentiated cells were observed under the inverted microscope.Inmmunocytochemistry was used in induced for 3-,5-,7-day cells to detect the expression rate of rhodopsin protein for the identification of phenotype of the differentiated cells.RT-PCR was used in induced for 5-,7-day cells to detect the expressions of rhodopsin mRNA and recoverin mRNA.Results Cultured BMSCs grew well with the spindle shape,and passaged RPE cells showed the uniform size and polygon shape with the abundant pigment in the cells.Some induced cells appeared to be the neuron-like cells with round shape and long prominence and the secondary reticular branches.The expression rates of rhodopsinin the cells were (5.83±0.29)％,(20.36±0.32)％ and (29.80±2.30)％ in the third,fifth and seventh day after induce,which were significantly higher than (0.71 ±0.35) ％,(2.56±0.24) ％ and (2.32±0.42) ％ of control cells (t3 d =41.510,t5d =107.290,t7 d =30.036,P＜0.01).The grey scales of rhodopsin mRNA and recoverin mRNA were significantly elevated in the induced and differentiated cells compared with control cells in the fifth and seventh day (rhodopsin mRNA:t5 d =103.506,t7 d =122.584,P＜0.01 ; recoverin mRNA:t5 d =106.674,t7 d =189.992,P＜0.01).Conclusions BMSCs can be successfully induced to differentiate into photoreceptor cells after cocultured by conditioned medium with RPE cells.

Objective To observe the effect of musky suppository in treating bleeding internal hemorrhoids. Methods The effects of 162 cases of bleeding internal hemorrhoids were observed. Results The time to take effect was 5 to 72 hours, average (22 ± 16.4)hours. After 7 days treatment, symptom improvement rate was as follows: bleeding 92.59%, erosion 87.80%, pain 91.80% , pruritus 75.93%, prolapsed 81.44%, swell 84. 35%. Conclusion Chinese medicine musky suppository is the primary choice for bleeding internal hemorrhoids, with apparent improvement for bleeding symptom, showing advantage of quick hemostasis, little side effect and safety.

Objective To probe into nursing management methods of replantation of amputated finger patients accepting brachial plexus block analgesia and patient-controlled sedation (PCS) after operation.Methods 48 patients of replantation of amputated fingers accept continuous brachial plexus block analgesia and PCS after operation,Analgesia was 0.2% ropivaeaine,sedation was 0.05% midazolam or compositive liquid mixed 0.05% midazolam and 0.0005% fentanyl,the visual analogue scale (VAS),sedation scores and the changes of vital signs and side effocts after operation were recorded before the operation and at time intervals of 6,12,24,48,72 hours after the operation.Results The visual analogue scale(VAS)in the post-operation was obviously lower than the pre-operation,the Ramsay scores of PCS were higher than the pro-operation.There was no inadequate or excessive sedation.No influence was seen on respiration,circulation system and no other side effects happened.Conclusions Brachial plexus block analgesia and patient-controlled sedation (PCS) can offer a good Analgesia and sedation effect for patients of amputated fingers replantation,in period of analgesia and sedation,we should strengthen nursing and monitoring of vital signs to avoid accident.

OBJECTIVE:To evaluate the role and function of hospital preparations.METHODS:A retrospective analysis was conducted on the utilization of hospital preparations in our hospital from July 1,2005 to June 30,2006.RESULTS:A total of 158 kinds of hospital preparations were used in our hospital,with their sales value totaling RMB 10.025 3 million,representing 1.13% of total drug sales.The top 10 selling hospital preparations accounted for 72.2% of all hospital preparations in sales value.A difference was seen in use of hospital preparations by outpatient and inpatient departments.CONCLUSIONS:Hospital preparations are indispensable for routine diagnosis and medication despite their small proportion in sales value of total drugs.

0.05),respectively.The adverse drug reactions(ADR)were characterized by different degree of myelosuppression,change in platelet,nausea and vomiting,alopecia etc,all were cured with symptomatic treatment.CONCLUSION:NP scheme enjoys good cost-effectiveness,but with severe ADR.For those patients had good economical condition and attach great importance to life quality,GP scheme is preferable.
