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.

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.

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.

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 compare the effect of difierent combinatio of mannitol, furesemide and albumin in reducing intracranial pressure in 451 patients with severe traumatic brain injury (sTBI). Methods A total of 451 patients with an admissiou Glasgow Coma Scale of or less from 5 medical centers were randomly divided into 5 groups, ie, Group A(250 ml 20% mannitol each time as control), Group B(125 ml 20% mannitol each time), Group C(alternate use of 250 ml 20% mannitol each time or 40 mg furosemide), Group D(alternate use of 125 ml 20% mannitol each time and 20 mg furosemide)and Group E(alternate use of 125 ml 20% mannitol and moderate or large dose of albumin). We monitored intracraniai pressure continuously and observed the changes of intracranial pressure, electrolytes, hemato-crit and renal function after use of 5 combinations of mannitol. Furosemide and albumin. Results Man-nitol and furosemide could independently reduce intracranial pressure after 1-3 hours (P<0. 05). Semis mannitol plus furosemide or albumin could more signifieantly reduce intracranial pressure, with statistical difference compared with full dose of mannitol. Semis mannitol and alternate use of mannitol and furose-mide in aspect of intracranial pressure reduction and persistence time(P<0. 05). Alternate use of man-nitol and furosemide begot higher incidence rate of electrolyte abnormality, compared with the other com-binations (P<0. 05). Rebound rate of intracranial pressure was higher in full dose of mannitol than other combinations (P<0. 05). Incidence of renal function abnormality was higher in combination involved al-bumin than alternative use of mannitol and furosemide as well as combination of semis mannitol and furo-semide (P<0. 05). Abnormality of electrolyte and renal function wag reversible. Conclusion The use of 125 ml 20% mannitol each time plus 20 mg furesemide is more reasonable than other combina-tions. Meanwhile, semis mannitol combined with moderate or large dose of albumin has certain advantages too.

In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.

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.
