Process Analysis of Mobile Fermentation of Spent White Hypsizygus marmoreus Substrate with Self-made Mobile Fermentation Bag

The self-made mobile fermentation bag for spent white Hypsizygus marmoreus substrate was developed, and the relevant fermentation process was studied. The results showed that under the condition of single addition of Lactobacillus,nitrogen-free extract was degraded into lactic acid, leading to decreased pH value.On day 10, the fermentation effect reached the best with Lactobacillus abundance of 5.12×10~7/ml, lactic acid content of 0.48% and strong acid flavor. At this time, the fermentation material was moist without mildew and agglomeration, and was suitable for livestock and poultry. However, after 10 days, undesirable acids and mildew generated, a large amount of lactic acid bacteria died, and the fermentation material turned black and agglomerated, and became unsuitable for feeding livestock and poultry. Throughout the fermentation process, the pH value first decreased continuously until to 4.0, and then remained stable. During the fermentation of spent white H. marmoreus substrate, the nitrogen-free extract and crude fiber contents decreased, the crude protein content increased, while other indicators remained unchanged.

Curative effect assessment of bandage contact lens in neurogenic keratitis

AIM: To observe the curative effect of bandage contact lens in neurogenic keratitis.METHODS: Twenty cases of neurogenic keratitis were studied at the Department of Ophthalmology, the First Affiliated Hospital of China Medical University, between October 2012 and June 2013. These included 13 males and 7 females, aged from 35 to 88 y. Patients were voluntarily divided into an experimental group(lens wearing group, n =10) and control group(drug therapy,n =10). In experimental group patients wore silicone hydrogel bandage soft contact lens. Both groups used the following eyedrops: 0.5% levofloxacin TID; 0.5%Sodium carboxymethyl cellulose QID; fibroblast growth factor BID; ganciclovir BID [cases complicated with herpes simplex virus(HSV)]; compound tropicamide BID(cases concurrent hypopyon). The healing time of corneal ulcer and complication rates were observed in the two groups.RESULTS: The healing time of corneal ulcer in the experimental group was 10.80±4.44 d versus 46.70±13.88 d in the control group(P 【0.05). No complications occurred in the experimental group, except for the lens falling off twice in one case, the patient recovered eight days after rewearing the lens. While in the control group, all cases vascularized, 2 cases were complicated with descemetocele that recovered with amniotic membrane transplantation and 1 case was complicated with corneal perforation that recovered by autologous conjunctival flap covering.CONCLUSION: Bandage contact lens is a safe and effective method of treating neurogenic keratitis andsignificantly shortened the healing time of corneal ulcer.

Clinic study on silicone hydrogel contact lenses used as bandage contact lenses after LASEK surgery

AIM: To compare the clinical performance of two types of silicon hydrogel contact lenses used as bandage lenses after LASEK surgery. METHODS: A prospective, double-masked study was conducted on 42 eyes of 21 patients who received binocular LASEK surgeries. The interocular difference in spherical equivalent power was less than -1.50D. Patients were randomly assigned to wear Galyfilcon A (Lens A) bandage contact lens in one eye and Balafilcon A (Lens B) in the fellow eye after the surgery. The responses to a subjective questionnaire on comfort of wearing, corneal epithelial status, conjunctival hyperemia, limbal neovascularization, lens fitting and contact lens debris were assessed 1 and 5 days postoperatively. Corneal endothelium was assessed before and 5 days after the surgery upon bandage lens removal. RESULTS: There was no difference between the two groups in terms of conjunctival hyperemia, limbal neovascularization, contact lens fitting, corneal epithelial status, corneal endothelium cell density (CD) and endothelium cell size (CS) at any postoperative visit. Complaints of discomfort, including foreign body sensation, pain and intolerance were statistically more among Lens B wearers at any postoperative visit (P < 0.05). Lens B appeared to attract much more debris than Lens A at the 5-day post-operative follow-up visit (P < 0.01). CONCLUSION: The two types of silicon hydrogel lenses investigated in this study demonstrated similar clinical performance in terms of corneal responses and lens fitting. However, Lens A showed a better performance in terms of comfort of wearing and deposit resistance.

Evaluation of the safety and efficacy of therapeutic bandage contact lenses on post-cataract surgery patients

AIM： To evaluate the safety of therapeutic bandage contact lens for post-cataract surgery patients and to illustrate its efficacy on post-operative comfort and tear-film stability. METHODS： A total of 40 participants were recruited and randomly divided into two groups. Group one was instructed to wear bandage contact lenses for a week and use antibiotic eye drops for a month since the first day after surgery. Group two received sub-conjunctival injection of tobramycin and was asked to wear eye pads on the first day after surgery and then were instructed to use antibiotic eye drops as the first group did. Ocular surface disease index（OSDI） questionnaire, slit-lamp microscope examination of tear break-up time（TBUT）, corneal fluorescein score（CFS）, tear meniscus height（TMH） together with anterior segment optical coherence tomography（AS-OCT） and corneal topography were evaluated preoperatively and postoperatively. RESULTS： The subjective feeling（P=0.004）, TBUT（P〈0.001） and TMH（P=0.02） post-surgery had improved in patients who used bandage contact lenses compared with those who did not at 1wk post-surgery. Until three month postoperatively, the comfort degree（P=0.004） and TMH（P=0.01） of group two were still worse than group one. Moreover, TBUT（P〈0.001） and CFS（P=0.004） of the group with eye pads got worse than the results before, whereas the group with bandage contact lenses recovered to normal. None of these patients had infections or other complications. CONCLUSION： Wearing therapeutic bandage contact lens after cataract surgery, compared with traditional eye-pads, is a safe method to improve tear-film stability and reduce post-operative discomfort without hindering corneal incision recovery.

Severe skeletal bimaxillary protrusion treated with micro-implants and a self-made four-curvature torquing auxiliary: A case report

BACKGROUND Bimaxillary protrusion is a clinically common dentofacial deformity,particularly among Chinese patients.This kind of malformation can severely affect facial esthetics and,even in mild cases,is difficult to correct without surgery.Unfortunately,many patients abandon treatment because of fear of surgery.Here,we describe a case of severe skeletal bimaxillary protrusion treated with nonsurgical orthodontic treatments,highlighting an alternative treatment option.CASE SUMMARY A 31-year-old woman wished to address a severe protrusion profile(approximately 8 mm overbite)and gummy smile.Cephalometric analysis and superimposition showed a severe skeletal class II pattern with a mandibular retrusion,and proclined and protrusive mandibular incisors.Panoramic radiograph showed a missing mandibular right third molar.A diagnosis of severe bimaxillary dentoalveolar protrusion was made.Taking into account the patient’s fear of orthognathic surgery,she accepted the proposed alternative treatment using micro-implants and a self-made four-curvature torquing auxiliary.The treatment allowed for maximal en masse anterior tooth retraction,proper relocation of incisors,and alleviation of the skeletal class II pattern.Esthetically,the patient’s lip protrusion was significantly decreased as was the overjet(from 10.5 mm to 1.8 mm),and the results remained stable throughout the 2-year followup.CONCLUSION Nonsurgical treatment using micro-implants and a four-curvature torquing auxiliary may benefit severe cases of skeletal bimaxillary protrusion in adults.

Geometry of the bandaging procedure and its application while wrapping bandages for treatment of leg ulcers

Appropriate compression bandaging is important for compression therapeutic medical diseases. The high compression approach employed for treating venous leg ulcers should be used correctly so that sufficient (but not excessive) pressure is applied. Bandages used to treat venous disease by compression should achieve and sustain effective levels and gradients of pressure and minimize the risk of pressure trauma. To maintain graduated compression on the limb, the bandage needs to be applied at the same tension for each layer from the ankle to the knee. In this paper, the geometry for various bandaging procedures is used to wrap each layer of bandage by marking the relaxed length of the bandage. The relaxed length is calculated depending on the stretch%, the average circumference of the limb to which it is to be applied and the bandaging technique to be used. This paper aims at developing a scientific approach while applying the bandage to reduce the inter operator variability in applying the same tension on each successive layer of bandage.

A Study of the Cytotoxicity of a New Nonwoven Polymeric Fibrous Bandaging Material In-Vitro

Traditionally used cotton-based bandaging materials have several disadvantages which can be overcome by using another fabric structure – nonwoven fabric. Moreover, these materials are more spongeous which increases their sorption capacity. The new bandaging material developed by the Institute of Physics of Strength and Material Science of the Siberian Branch of the Russian Academy of Sciences has even better sorption capacity with improved sorption properties. Its sorption capacity has been increased by means of an additional introduction of porous aluminum hydrate particles into fabric. It is important that a bandaging material has a good biocompatibility and does not have any cytotoxic effect on cells and tissues. Here it is present results of the study of the material's direct contact and indirect cytotoxicity assays in comparison with cotton gauze. It have found that in the direct contact of nonwoven polymeric fibrous bandaging material (NPFBM) with cells for 24 hours of cultivation no changes in cell morphology take place, nor does the amount of dead cells increase. These conclusions have been made by means of both a visual examination and an МТТ assay. The NPFBM extract did not have any cytotoxic effect on the tested cells either. The obtained results allow us to make a conclusion that the NPFBM complies with the international standard ISO 10993-5, which is applied to medical goods, and can from now on be applied in the treatment of infected wounds in clinical practice.
