Age-related macular degeneration (AMD) has become one of the leading causes of irreversible blindness worldwide.With the advancement of stem cell technology,tissue engineering and biomaterials,cell-based therapy has been inspiring for many degenerative diseases.For its unique advantages,AMD has become one of the most promising fields for cell-based therapy,which involve retinal pigment epithelium(RPE)cells,induced differentiation of neural retina cells and related cytokine regulations.RPE cells can be derived from human embryonic stem cells (hESC) or Induced pluripotent stem cells (iPS).Recently hESC-derived RPE cells have been applied to patients with dry AMD with initial success in clinical trials.In terms of tissue engineering,studies are focused on factors affecting the long-term survival of transplanted cells,including tissue scaffolds,soluble hybrid materials and scaffold anchoring.This article briefly reviews the RPE differentiation,neural retina differentiation and related cytokines of cell-based therapy and scaffolds,materials,and cell-scaffolds interactions of tissue engineering in AMD treatment.

[Objective]To observate the successive status of chondrocyte apoptosis after impacting injury of articular cartilage by TUNEL marking method and transmission electron microscope(TEM).[Method]Fifty-six New Zealand adult rabbits were divided randomly into low-energy and high-energy two groups,each group was 28.Femoral medial condylar cartilage of one side was injuked by impacting in experimental group,the opposite side as control group.Four rabbits were killed and their medial femoral condylar cartilages were taken at each of the following intervals:4 days,1,2,4,8,16,32 weeks after impacting injury.The specimens were observed as pathology histological sections and strained by TUNEL to measured the rate of chondrocyte apoptosis.[Result]In early stage of post-injury,the rate of chondrocyte apoptosis in and high-energy is significantly higher than that of control group.After 4 weeks,the rate of chondrocyte apoptosis decreases to the level of that of control group in low-energy.In high-energy group,the rate of chondrocyte apoptosis is constantly upgraded-phase,higer significantly than the level of that of control group.[Conclusion]In early stage of post-injury,the rate of chondrocyte apoptosis in low and high-energy was significantly higher than that of control group.After 4 weeks,the rate of chondrocyte apoptosis decreased to the level of control group in low-energy.In high-energy group,the rate of chondrocyte apoptosis is constantly upgraded-phase,higer significantly than the level of control group.

Objective To evaluate the efficacy of percutaneous CT guided interstitial 125Ⅰ seeds implantation treatment for refractory pelvic malignant tumors and discuss the procedure of technique.Methods Twenty-three patients with refractory pelvic malignant tumors(25 lesions,diameter 3.5-7.0 cm,mean 4.5 cm) showing failure response to full chemotherapy and/or radical radiotherapy after tumors resection were undergone percutaneous CT guided intratumoral 125Ⅰseed implantation.Treatment plan system(TPS)was used to design the distribution and number of 125Ⅰ seeds according to matched peripheral dose(MPD)1-3 days before the procedure.Of which 6 cases received combined internal iliac arterial infusion chemotherapy before or after the 125Ⅰ seed implantation procedure.Results 9 ～ 75(mean 27)125Ⅰ seeds were implanted into a single tumor at first time including 6 patients with intraarterial chemotherapy for 14 cycles(mean 2.3 cycles),showed relief of clinical pain symptoms in 16 of 23 cases,72 h ～ 4 w after the seeds implantation;with the an effective rate of 69.6%.Follow up for 2-34 months(median,21 months),CT or MRI performed 2 months after the seeds implantation showed no CR,but PR in 18 cases,SD in 4 cases,and PD in 1 case,with overall response rate of 78%(18/23),and no serious complication.In addition,20 cases survived,with the longest one of 34 months and the other 3 died.Conclusions Intratumoral 125Ⅰ seeds implantation under CT guidance for pelvic refractory malignant tumors is safe,minimally invasive,and effective.

Objective To investigate the synergistic effects of 9-cis-retinoic acid(9-cis-RA) and 8-cl-cAMP on growth inhibition and apoptosis induction in H460 and H292 cell lines of non-small-cell lung cancer(NSCLC). Methods Experimental groups included 9-cis-RA groups(1,5,10 and 20 ?mol/L),8-cl-cAMP groups(5,10,20 and 50 ?mol/L),9-cis-RA(5 and 10 ?mol/L) combined with 8-cl-cAMP(10 ?mol/L) groups and blank control group.The cell growth inhibition rates were detected by trypan blue staining,and the apoptosis of H460 and H292 cells were observed by Hoechst33258 fluorescence microscope,DNA gel electrophoresis and flow cytometer(FCM). Results 9-cis-RA inhibited the growth of H460 cells in a time-and dose-dependent manner,and induced the apoptosis of H460 cells(P

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.

METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.

RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.

CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

OBJECTIVETo dynamically observe the effect of Shenshuai Mixture (SM) on repair of kidney in acute renal failure (ARF) rats.

METHODSMale SD rats were divided into 4 groups randomly, the normal group, the SM group, the verapamil group and the model control group. Except those in the normal group were treated with normal saline without modeling, all remaining rats, after being made into ARF model by intra-muscular injection of glycerin, were treated with SM, verapamil and normal saline respectively via gastrogavage. Renal function, renal pathology, mRNA expression of epidermal growth factor (EGF) and protein expression of proliferating cell nuclear antigen (PCNA) were detected once every day from the 1st day to the 5th day. Results (1) BUN and Scr levels increased markedly 24 hrs after modeling, but the Scr level in the two treated groups was significantly lower than that in the model group (P < 0.05). Compared with that in the model group and the verapamil group, renal function was better in the SM group on the 3rd day (P < 0.01), and approach to normal level on the 5th day. (2) Renal pathological changes alleviated in every phase of ARF in the SM group than that in the model group, especially part of tubule regeneration could be seen on the 3rd day (metaphase), and renal structure was rehabilitated on the 5th day (convalescence), prior to those in the model group. (3) At the 3rd day expression of EGF mRNA and PCNA in tubule epithelial cell (TEC) increased remarkably in the SM group, higher than those in the model and verapamil group (P < 0.05).

CONCLUSIONSM could promote renal tissue regeneration and rehabilitation, and shorten the course of ARF through up-regulating mRNA expression of EGF in TEC.
