AlM:To investigate the effect of peripheral vision control technology for delaying the development of juvenile myopia.METHODS:A total of ninty-nine cases of 12 ~18 year-old myopic patients were randomly divided into two groups. The experimental group was peripheral vision control technology group whose members wore the special lenses which can help correct the hypermetropic defocus of peripheral retina. The other was control group whose members wore ordinary monofocal lenses. All the subjects needed to accept re-examination every 3mo and be recorded the data of dioptre, corneal curvature and axial length.RESULTS: After 18mo, the dioptre and axial length of two groups had increased in varying degree. But the data's different quantity of the corneal curvature in each group had no statistical significance ( P > 0. 05 ). Themyopia deepen quantity in experimental group was-0. 65±0. 65D and its axial growth was 0. 23±0. 22mm, and the myopia deepen quantity in control group was -1. 17 ± 0. 50D and its axial growth was 0. 41 ± 0. 17mm. Under the circumstance of valid data, the increment of myopia and axial length in experimental group was lower than that in control group (P<0. 05).CONCLUSlON: Peripheral vision control technology can delay the development of juvenile myopia effectively.

Insulin resistance and insulin secretion deficiency are main machanisms in inducing type 2 diabetes mellitus (T2DM), and mitochondria damage plays an important role in them. Research shows that autophagy is a self-protective mechanism of cells, which plays an important role in maintaining the normal structure and function of pancreatic β cells and improving insulin resistance. Previous studies show that traditional Chinese medicine can regulate cell autophagy to influence β cells and insulin resistance, type 2 diabetes mellitus and its complications. Thus this review will talk about the process of the relationship between autophagy and T2DM and the intervention effect of traditional Chinese medicine.

Objective: To establish the fingerprint chromatogram of Tongguanteng Injection (caulis Marsdeniae Tenacissimae). Methods: HPLC with ZORBAX SB C 18 column was used, the (a) 0.05% H 3PO 4 H 2O and (b) ACN 0.05% H 3PO 4 H 2O (13∶87) (gradient elution) as a mobile phase and detection wavelength at 254nm. Results: 22 peaks were indicated on the HPLC fingerprint of Tongguanteng Injection. The relative retention time and relative peak area were obtained with itself peak at retention time 48.5 min. Conclusion: The method is simple and accurate with a good reproducibility and can be used as a quality control method for Tongguantent Injection.

AIM:To investigate how to design personalized cataract surgery programs to achieve surgical correction of preoperative corneal astigmatism with surgical astigmatism under the guidance of corneal topography, improve postoperative visual quality and reduce the cost of treatment.
METHODS: Totally 202 cases ( 226 eyes ) cataract patients were divided into randomized treatment group and individualized treatment group. According to the method and location of the incision, randomized treatment group were divided into 8 groups. Surgical astigmatism after different incision were calculated with the use of preoperative and postoperative corneal astigmatism through vector analysis method. Individualized treatment groups were designed personably for surgical method with reference of every surgically induced astigmatism, the surgical method chooses the type of surgical incision based on close link between preoperative corneal astigmatism and surgically induced astigmatism, and the incision was located in the steep meridian. The postoperative corneal astigmatism of individualized treatment group was observed.
RESULTS: Postoperative corneal astigmatism of individualized treatment group were lower than that of 3.0mm clear corneal tunnel incision in the randomized treatment group, there were statistically significance difference, while with 3. 0mm sclera tunnel incision group there were no statistically significance difference. After 55. 8% of patients with the use of individualized surgical plan could undergo the operation of extracapsular cataract extraction with relatively low cost and rigid intraocular lens implantation, the per capita cost of treatment could be reduced.
CONCLUSION: Personalized cataract surgery programs are designed to achieve surgical correction of preoperative corneal astigmatism under the use of corneal topography, improve postoperative visual quality and reduce the cost of treatment.

AIM: To establish the quality standard for Gubiling Capsules (Penis Et Testis Canis, Radix Noto ginseng, Radix Achyranthis Bidentatae, Herba Epimedii, Radix Aucklandiae, etc.). METHODS: Radix Achyranthis Bidentatae, Herba Epimedii, Radix Aucklandiae were identified by TLC, and the ginsenoside Rg 1 content was determined by HPLC. RESULTS: Ginsenoside Rg 1 showed a good linear relationship in the range of 1.2-6.0 ?g ( r = 1.00 0 ) and average recovery was 96.9%. RSD was 0.4%. CONCLUSION: These methods are simple, accurate and specific and can be used for the quality control for Gubiling Capsules.

Background Orthokeratology has been proved to temporarily alter the equivalent sphere,but its effects on visual quality deserve attention.Objective The present study was to investigate the visual quality after overnight orthokeratology in pre-adolescent myopes.Methods Written informed consent was obtained form each subject prior to entering into this series.A descriptive study design was used.One hundred and fifty eyes of 76 teenagers aged (14.90± 1.24)years with low and moderate myopia (-2.79 ± 0.82)D were included in the study.Fitted with Ortho-K contact lens,the lens was wore every night for over 8 hours.Subjective refraction,uncorrected visual acuity (UCVA),contrast sensitivity function,corneal-topography,and aberrometry were examined before,1 week and 3 months after the initiation of orthokeratology.Visual quality was generally evaluated by comparing before wearing,1 week and 3 months after wearing using the National Eye Institute refractive error quality of life instrument (NEI-RQL-42TM).All the procedures were performed by the same clinician.Results Spherical equivalent refractions were (-0.33± 1.02) D and (-0.26 ± 0.60) D 1 week and 3 months after orthokeratology,showing significant decline in comparison with (-2.79±0.82) D of before orthokeratology (P =0.001,0.001).However,no considerable difference was seen between 1 week and 3 months after orthokeratology (P=0.161).Contrast sensitivity function was significantly different in all spatial frequencies before wearing,1 week and 3 months after wearing,and those of 1 week and 3 months after wearing were significantly lower than those of before wearing (1 week:3 cpd P =0.001,6 cpd P=0.001,12 cpd P＜0.05,18 epd P＜0.05 ;3 months:3 cpd P=0.001,6 cpd P=0.001,12 cpd P＜0.05,18 cpd P＜0.05).There was no significant change in contrast sensitivity function between 1 week and 3 months of orthokeratology (P＞0.05).Flat K,steep K and corneal eccentricity (e) were significantly reduced (P =0.000),and surface asymmetry index (SAI) and surface regularity index (SRI) were significantly improved after orthokeratology in comparison with before orthokeratology (both P =0.001).Root mean square (RMS) of total higher-order,third-order and fourth-order aberrations were significantly increased (P＜0.05),but RMS of whole aberration and second-order aberrations significantly decreased after orthokeratology (P＜ 0.05).There were no significant changes in the fifth-order,sixth-order and seventh-order aberration among pre-wear,1 week and 3 months after orthokeratology.Scales of dark to bright,nocturnal driving,glare,visual fluctuate and halo were lower than those before orthokeratology (P＜0.05).The scales of visual fluctuate between 1 month and 3 months after orthokeratology had significant differences (P＜0.01),while the rest of the scales had no significant differences (P＞0.05).Conclusions Orthokeratology can reduce myopic diopter 1 week after orthokeratology.The overnight wearing of fitted orthokeratology can decrease contrast sensitivity and increase corneal surface irregularity and RMS of third-order and fourth-order.Compared with spectacles,orthokeratology reduces subjective visual quality,especially nocturnal quality.

Eight 1,6-O,O-diacetylbritannilactone (OABL) derivatives (compounds 1-8) were synthesized by esterification or reduction of 1-O-diacetylbritannilactone (ABL) isolated from Inula japonica.All derivatives were evaluated for their anti-inflammation activities through the determination of inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages.As results,compounds 5-8 (IC50 ＜ 2 μmol/L) exhibited more potent inhibition of NO production activities than the lead compound OABL.
