Objective To study the clinic features and prognosis of juvenile rheumatoid arthritis (JRA)-associated iridocyclitis.Methods Ten cases of JRA -associated iridocyclitis choosed from 107 cases with JRA were reviewed and analysed.Results Polyarticular( n =9) and pauciarticular( n =1) were observed among JRA -associated iridocyclitis.Four were acute cases and all were recovered.Secondary glaucoma ( n =1) and ablepsia( n =1) were find in the chronic cases of 6,respectively.Conclusions Iridocyclitis is a common complication of JRA. Most of them are polyarticular group. The acute cases have better results compared to the chronic cases which often have more complications such as glaucoma,cataract, et al .

BACKGROUND:Experiments have shown that the col agen substrate has the capability of stimulating cartilage generation, but the stimulating role of different types of col agen substrates remains controversial. OBJECTIVE:To investigate the effect of type I and type II col agen on the biological characteristics of human chondrocytes cultured in vitro. METHODS:Human chondrocytes at passage were cultured onto the ordinary culture plates (ordinary plate), type I col agen-coated culture plates (type I plate), and type II col agen-coated culture plates (type II plate). cellgrowth curves were determined by MTT method after cells were cultured for 10 days. By ELISA, PCR, and 1,9-dimethyl methyleneblue technology, type I and type II col agen and glycosaminoglycan contents were quantitatively detected in cartilage cells 28 days after culture. RESULTS AND CONCLUSION:The number of cartilage cells was the highest in type II plate, which was twice of that in type I plate and five times of that in ordinary plate. Cartilage cells in type II plate secreted the least amount of type I col agen, which showed significant differences compared with the ordinary plate (P<0.01) and had no statistical y significant difference with type I plate (P>0.01). Cartilage cells in type II plate secreted the most amount of type II col agen and glycosaminoglycan, showing significant differences compared with the other two plates (P<0.01). The cartilage cells cultured in col agen plates are better than that cultured in ordinary culture plate, type II col agen culture plate is better than type I col agen culture plate in maintaining cellshape, extending the dedifferentiation pattern, and promoting celldifferentiation.

Ultrasound contrast agent microbubbles combined with low frequency ultrasound named as low-frequency ultrasound-targeted microbubble destruction technology has become an effective and non-invasive anti-tumor therapy for deep tumors.It can enhance the efficacies of chemotherapy,gene therapy,immunotherapy,and anti-angiogenic therapy by improving cell membrane permeability and destroying tumor neovasculature.It can be applied to sonodynamic therapy and realize multimodal synergistic therapy on the basis of nanoparticles,which increases the anti-tumor efficiency and offers a promising target therapy for tumors.

Culling protein is a member of Cullin-Ring-based E3-ligases ( CRLs family) , which belong to E3 ubiquitin ligases. Cullin plays diverse and essential roles in many biological processes through mediating the ubiquitination of target proteins. This article summarizes the potential functions of Culling proteins in gamete genesis and maturation, embryo development, and reproductive related disorders.

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

Objective To compare the effects of vitrification with slow-freezing on the developmental ability of day 3 cleavage stage embryos.Methods Patients who had no less than 4 high quality embryos were included in this study.These embryos were cryopreserved using the methods of vitrification or slow-freezing.In the eryopreserved embryo transfer cycles,the embryos which were cryopreserved using one of the methods were chosen randomly.The developmental ability of embryos was compared between these two groups.Results A total of 80 patients were included in this study with 160 embryos.In the group of slow-freezing,73(91%)embryos were survived and achieved 15(38%)clinical pregnancies.Among these,3 were twins and the implantation rate was 25%(18/73).In the group of vitrification,71(89%)embryos were survived and achieved 19(48%)clinical pregnancies.Among these, 9 were twins and the implantation rate was 39%(28/71),which was significantly higher than the slow- freezing group(P

Objective: To optimize preparation techniques for Herba E pimedii flavonoid phytosomes (EFP) and explore their suitable pharmaceutics. Methods: To optimize the preparation conditions by means of unifo rm design and step regression, prepare Herba Epimedii total flavonoid phytosomes by means of solvent evaporation and investigate the accumulative dissolution of different ratios of EFP-PVP precipitates by means of dissolution release. Resu lt: The optimized preparation conditions are as follows: solvent-tetrahydrofura n, lecithin to PVP-2.5 times, temperature-40　℃ and reaction-3 hours. Oil/wa ter apparent partition coefficient of icariin was enhanced more than 4 times by phospholipid. The accumulative dissolution of Herba Epimedii flavonoids of EFP- PVP precipitate was significantly higher than that of its physical mixture and H erba Epimedii extract tablet. Conclusion: Phospholipid can ef fectively enhance the oil/water apparent partition coefficient of icariin, and P VP can improve the dissolution of Herba Epimedii phytocomes, but the pharmacokin etics needs further study.
