AIM: To report a two- year's results of iontophoresis-assisted transepithelial corneal cross-linking (I-CXL) for progressive keratoconus.
METHODS: Thirty - four eyes in 24 patients with progressive keratoconus ( mean age 21. 0 ± 5. 6 years;range: 14-32 years) were treated. After 1g/ L riboflavin-distilled water solution was administered by iontophoresis-assited (current 1mA) transepithelial method for 5min in total, standard surface UVA irradiation ( 370nm, 3mW/cm2 ) was performed at a 1 - cm distance for 30min. The best corrected visual acuity ( BCVA ) measured as LogMAR number, corneal refractive astigmatism, K1, K2, Kmean, Kmax, intraocular pressure, endothelial cell density, the thickness at corneal apex and the thinnest point were measured preoperatively and 2a postoperatively.
RESULTS:At 2a after the procedure, BCVA (LogMAR) improved from 0. 32 ± 0. 25 to 0. 25 ± 0. 19 ( t = 2. 849, P =0. 015). K1 decreased from 47. 12±4. 33 to 46. 06±4. 77 (t =2. 652, P= 0. 015). K2 decreased from 51. 36±5. 59 to 50. 40±6. 16 (t= 2. 121, P= 0. 047). Kmean decreased from 49. 12±4. 76 to 48. 10±5. 25(t = 2. 663, P = 0. 015). Kmax decreased from 57. 57±8. 30 to 55. 91±8. 14 (t = 2. 398, P = 0. 026). The corneal apex thickness decreased from 476. 90±38. 71μ m to 454. 43 ± 40. 86μ m ( t = 2. 853, P = 0. 010 ). The thinnest thickness decreased from 464. 38 ± 39. 92μ m to 433. 86 ±50. 78μ m ( t = 3. 485, P = 0. 002 ). Corneal refractive astigmatism, intraocular pressure and endothelial cell density did not show significant changes.
CONCLUSION: I - CXL for progressive keratoconus is safe and effective which can prevent deterioration of progressive keratoconus within 2a, but further long-term studies are necessary still.

In this paper 3 different media (A,for yeast cultivation ; B, for laccase producing; D, for white rot fungi cultivation) were compared in enriching and screening decolorizing fungi culture using Reactive Black 5 (RB5) and Reactive Red (M-3BE) from the following three points: decolorization effects, abilities of producing enzymes and diversity of microbial community. 11 groups of fungi with obvious decolorization effects were obtained after enrichment for near one month. Among them, 6 groups came from medium D, the other two 3 groups from medium A and B, respectively. However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae (Monascus went), Erysiphaceae and Physodermataceae. Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae (Penicillium) were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

OBJECTIVETo study the diagnosis and microneurosurgical treatment of cavernous sinus neurinoma.
METHODSTwenty-two patients with cavernous sinus neurinoma which had been diagnosed by MRI were operated on by microsurgery. Fourteen patients received excision of tumor through frontotemporal approach with zygomatic osteotomy and, 8 patients via subtemporal and suboccipital transtentorial approaches.
RESULTSTotal resection was achieved in 21 patients (95.5%), and subtotal resection in 1. There was no operative death. The all operative samples were confirmed neurinoma pathologically. The symptoms postoperation such as headache and exophthalmos were reduced. Three months after operation, the function of the 6th nerve was improved in 12 of 19 patients with paresis of the 6th nerve. One patient with hemiplegia recovered well. The function of the 3th nerve recovered in 4 of 6 patients with recurrent paresis of the 3th nerve. Those patients with hydrocephalus were improved after operation. The patients were follow up 8 - 60 months (mean 20 months). No tumor recurrence was observed.
CONCLUSIONCavernous sinus neurinoma can be removed successfully via subtemporal and suboccipital transtentorial approaches.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.
METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.
RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.
CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

Objective To investigate the relationship between expression of active form of caspase-3 and cell cycle in Fas-mediated apoptosis of B lymphocytoma cell line MML-1. Methods MML-1 cells were incubated with agonistic anti-Fas antibody for different time,and cell apoptosis was induced.Cell apoptotic rates were analysed by flow cytometry,and sensitivity of MML-1 cells to apoptosis was determined.The expression of active form of caspase-3 was analysed by double staining with PI-Triton X and FITC-active caspase-3.Cyclin A,B_1 and E were selected as cell cycle markers for S,G_2/M and G_1 phase of MML-1 cells,and the expression of active form of caspase-3 was detected by flow cytometry. Results The cell apoptotic rate reached 56% after induction by Fas for 6 h.After induction by Fas for 4 h,the active form of caspase-3 was mainly expressed in cells of G_1 phase,while rarely in cells of S and G_2/M phase.Cells with negative cyclin A and B_1 and positive cyclin E expressed active form of caspase-3. Conclusion The expression of active form of caspase-3 in MML-1 cells mediated by Fas might be cell cycle dependent.Cells entering into late G_1 and early S phase first express active form of caspase-3,and their sensitivity to Fas-mediated apoptosis is the highest.

AIM: To study the effect of dexamethasone(Dex) on the expression of CD18. METHODS: Quantitative RT-PCR analysis, Northern blotting technique were used to measure the expression of CD18 in U937 cells treated by PMA. RESULTS : Dex could significantly attenuated the effects of PMA in a dose-dependent manner (10 -6 mol/L-10 -10 mol/L). These effects of Dex (10 -7 mol/L) were completely aborted by RU-486 (10 -6 mol/L).CONCLUSION: Dex, via GR, could inhibit CD18 mRNA expression in U937 cells treated by PMA. The effects of Dex might be possibly depended on the counteracting action on the NF-?B.
10.Research progress of cylindrical abdominoperineal resection/extralevator abdominoperineal excision for advanced low rectal cancer.
Chinese Journal of Gastrointestinal Surgery 2012;15(10):1013-1016
Cylindrical abdominoperineal resection (CAPR), also known as extralevator abdominoperineal excision (ELAPE), has been described as a method for improving the outcome of APR for advanced low rectal cancer, probably because of more pelvic dissection and less positive circumferential resection margin (CRM). Recently, there have been some hot issues associated with CAPR/ELAPE, such as pelvic floor reconstruction methods, prone or lithotomy positioning during pelvic procedure, postoperative chronic perineal pain, postoperative sexual and urinary nerves damage, etc. Individual cylindrical procedure based on clinical and anatomic research may be as effective as CAPR/ELAPE while minimizing the operative trauma and the damage to the nerves of the genital and urinary organs.
