0.05). Conclusion Aspirin-vitamin C dispersible tablets is effective and safe for treating patients with URI.

AlM: To investigate the clinical effect of preserved amniotic membrane transplantation in the treatment to conjunctival rupture, dehiscence and socket contracture after hydroxyapatite ( HA) orbital implantation.
METHODS: ln 16 cases of conjunctival rupture and socket contracture after HA orbital implantation, conjunctival tension was release by operation and preserved amniotic membrane was transplanted on conjunctival scleral exposure area.
RESULTS:ln all cases, conjunctiva healing, completely cover the sclera and conjunctiva socket recover ideal depth after operation in 15 cases, 1 case was fail.
CONCLUSlON: Preserved amniotic membrane transplantation is an effective method to treat conjunctival dehiscence and keeping the ideal conjunctival socket depth after orbital implantation.

AIM: To analyze the results of phacovitrectomy with internal limiting membrane(ILM) peeling to treat foveoschisis in ultra-high myopia.METHODS: Totally 32 eyes of 32 ultra-high myopia patients with foveoschisis were selected retrospectively.The preoperative refractive errors ranged from-12.00D to-20.00D with the mean of-15.78±2.16D.The best corrected visiual acuity(BCVA) were converted to LogMAR acuity, and the average BCVA was 4.1±0.4.Conventional phacovitrectomy with ILM peeling by ICG dying were performed.Gas tamponade were performed to end the operation.The BCVA and the foveoschisis cavity were observed by 1-9mo after the surgery, with the mean of 4.5mo.RESULTS: The foveoschisis cavity of 30 eyes were healed with BCVA increased and visual distortion alleviated distinctly (94%)(t=-7.91, P<0.05).CONCLUSION: Phacovitrectomy with ILM peeling is useful in treating foveoschisis in ultra-high myopia with visual function preserving.

Objective To investigate the optimal scheme about the external loading of resetting tensile stress for clavicular fracture,so as to provide some mechanical references for optimal design of external fixators for clavicular fracture.Methods The shoulder CT scanning data from a volunteer were used to establish the three-dimensional model of human left shoulder by Mimics software.In order to better simulate the actual human shoulder,the ligament tissues were added in the model and the constraints of muscles were considered,and the experimental model for simulation analysis on resetting tensile stress was established.By 3 simulation experiments,the impacts from directions of resetting tensile stress,positions of action points and value ranges were simulated and analyzed,respectively.The resetting tensile stresses obtained from clavicle of the shoulder model under various external loading cases were simulated by orthogonal test methods.Results When the θ (angle between the horizontal plane projection of shoulder force which was loaded by external fixator and the coronal axis) was greater than 45°,clavicle could obtain the resetting tensile stress,which became greater with the angle θ increasing.When η (angle between the sagittal plane projection of shoulder force which was loaded by external fixator and the sagittal axis) was 30°-45°,the resetting tensile stress of clavicle was the maximum.The farther the position on which the loads from external fixator was exerted from the horizontal position of clavicle,the larger the resetting tensile stress of clavicle was.Conclusions The results of orthogonal test show that the optimal resetting tensile stress is produced with parameter combination of θ =65°,η =50°,acting on the center of humerus head of the shoulder.

To develop a new small molecular probe for discovering an antitumor lead compound from the replacement of carboxylic group of two molecular antibacterial fluoroquinolones with a heterocyclic ring, a series of the C3/C3 bis-fluoroquinolones tethered with an 1, 3, 4-oxadiazole ring were synthesized as their respective HCl salts, and their structures were characterized by elemental analysis and spectral data. The in vitro antitumor activity against L1210, CHO and HL60 cell lines was also evaluated via the respective IC50 values by methylthiazole trazolium (MTT) assay.

OBJECTIVETo determine the expression of Skp2 in different prostate cancer (PCa) cell lines and tissues, and explore its influence on the androgen receptor (AR) signaling pathway and development of castration-resistant prostate cancer (CRPC).

METHODSThe expression levels of Skp2 and AR in different PCa cell lines were detected by Western blot. After knockdown of Skp2 in the C4-2 and 22RV1 cells transfected with shRNA, the expressions of AR and P27 were determined and the activity of ARR3-Luc measured by dual-luciferase reporter gene assay following treatment with dihydrotestosterone (DHT). The expressions of AR and Skp2 in human naïve PCa or CRPC specimens were detected by immunohistochemical staining followed by analysis of their differences and correlation.

RESULTSThe Skp2 protein expression level was significantly higher in the C4-2 or 22RV1 cells than in the LNCaP cells. DHT treatment increased the expression of Skp2 in the C4-2 cells, but knock-down of Skp2 significantly up-regulated the expression of the well-known downstream protein P27 and down-regulated that of AR. Consistently, DHT treatment increased the activity of ARR3-Luc, while knockdown of Skp2 remarkably decreased it in the C4-2 and 22RV1 cells (P < 0.05). In addition, significantly higher expressions of Skp2 and AR were observed in the CRPC than in the naïve specimens (P < 0.05), with a positive correlation between the two proteins (r = 0.658 1, P < 0.05).

CONCLUSIONSkp2 can enhance the expression and transcription activity of the AR protein in CRPC cells or tissues and is promising to be a critical molecular therapeutic target.
