BACKGROUND:Fibroin is a natural macromolecular material with Arg-Gly-Asp peptide structure that is a special tripeptide structure closely related to cel adhesion, and it can promote cel migration, adhesion, and proliferation and influence cel morphology and function. OBJECTIVE:To compare the effects of different silk fibroin scaffolds to repair buccal mucosa defects in rats. METHODS:Ninety Sprague-Dawley rats were selected to make unilateral buccal mucosa defect models, and randomly divided into three groups, 30 rats in each group: porous silk fibroin scaffold was implanted into the buccal mucosa defect in experimental group, multi-layered crosslinked silk fibroin film was implanted into the buccal mucosa defect in control group, and vaseline gauze was used to cover the buccal mucosa defect folowed by suturing in blank control group. After 15 days, wound diameter was detected; after 30 days, bone defect tissues were taken for hematoxylin-eosin staining. RESULTS AND CONCLUSION:At postoperative 15 days, the wound diameter was significantly smaler in the experimental group than the control and blank control groups (P < 0.05), as wel as smaler in the control group than the blank control group (P < 0.05). Hematoxylin-eosin staining showed that at 30 days after operation, there were more epithelial spikes and fibroblasts, but less inflammatory cels in the experimental group than the other two groups (P < 0.05), and fibroin fibers were partialy absorbed and degraded in the experimental group. These findings indicate that porous silk fibroin scaffold for buccal mucosa defect repair can accelerate epithelialization and wound healing.

In spite of much progress on its mechanism, diagnosis and treatment, diabetes mellitus remains a public health challenge. The harm of diabetes is not significantly reduced, instead shows an increasing tendency year by year. To achieve an in?depth and comprehensive understanding of the underlying mechanism, and to develop efficacious, stable and hypoglycemia?risk free drugs, it is crucial to gain more knowledge about diabetes from animal models. In this review, the types of diabetes animal models, modeling methods, the advantages and disadvantages, their applicable scope are discussed aiming to provide a reference for researchers to choose appropriate animal models.

BACKGROUND:Researches have found that minocycline plays a neuroprotective effect by inhibiting the microgliacel proliferation and activation and suppressing glial cels to release cytokines and chemokines. OBJECTIVE:To investigate the influence of minocycline on glial cel line derived neurotrophic factor, NTN and gene expression in substantia nigra and corpus striatum in Parkinson’s disease model rats.
METHODS:144 rats were randomly divided into four groups, with 36 rats in each group. In the normal control group, no intervention was given. In the model and experimental groups, 6-hydroxydopamine was injectedin the right substantia nigra pars compacta and ventral tegmental area to establish Parkinson’s disease models. In the sham surgery group, vitamin C was injected in the two points. In the experimental group, after model establishment, rats were intragastricaly given 4.5 g/L minocycline 45 mg/kg. From then on, additional 22.5 mg/kg minocycline was added every 12 hours. The last group was normal control group. Immediately, 12 hours, 1, 7, 14 and 21 days after model induction, SP immunohistochemistry was used to detect the expression of glial cel line derived neurotrophic factor and NTN expression in the substantia nigra and corpus striatum. RT-PCR was used to identify glial cel line derived neurotrophic factor and NTN mRNA expression in the substantia nigra and corpus striatum.
RESULTS AND CONCLUSION:Both in the substantia nigra and corpus striatum, the positive cel number and relative gene expression of glial cel line derived neurotrophic factor and NTN were lower in the model group than in the normalcontrol and sham surgery groups (P< 0.05). Glial cel line derived neurotrophic factor-and NTN-positive cel number and relative expression were higher in the experimental group than in the model group (P< 0.05). These findings suggest that minocyclinecan delay the process of Parkinson’s disease pathogenesis by promoting glial cel line derived neurotrophic factor protein and gene expression.

BACKGROUND:The sensitivity andmucus secretion of theoral mucosamake oral soft tissues difficult to repair, so patients cannot achieve satisfactory outcomes after treatment. Nano-celulose protein mainly composed of glycine, alanine and serine has good histocompati bility. However, there is a lack of comparative study about the effect of nano-celulose protein and acelular matrix in oral mucosa repair, and the clinical effects of the two materials are stil under discussion.
OBJECTIVE:To investigate the effects of nano-celulose proteinver susacelular matrix in oral mucosa repair.
METHODS:Oral mucosadefect models were preparedinrats, and these rat models were randomly divided into four groups:oral mucosa defectswere repaired by vaseline (control group), nano-celulose protein, bovine skin acelular matrix and human skin acelular matrix, respectively. Repair effects were compared among different materials within 2 months after surgery.
RESULTS AND CONCLUSION:The diameter of oral mucosa defect measured using a vernier caliper, had no significant differences among groups at 1 day after surgery (P> 0.05); the diameter of oral mucosa defect in the nano-celulose protein group was significantly lower than that in the other groups at 3, 5 and 7 days after surgery (P<0.05); the diameter of oral mucosa defect in the bovine and human skin acelular matrix groups was significantly lower than that in the control group at 5 and 7 days after surgery (P< 0.05). Morphological observationoftheoral mucosa under light microscope showed: the number of newborn capilary endothelialcels in the defect region had no significant differences among nano-celulose protein, bovine acelular matrix and human acelular matrixgroupsat 1, 3, 5 and 7 weeks after surgery (P> 0.05);but there were significant differences in the number of newborn capilary endothelialcels between the control group and the other three groups (P< 0.05). Furthermore, at 21 days after surgery, closely aligned and thicker new epithelialtissuecould be found in the nano-celulose protein group; in the bovine acelular matrix group,thedefect regionwasrepaired wel, new epithelialtissueappeared andthe number of inflammatory cels decreased; in the human acelular matrix group, inflammatory cels appearedobviously, and new epithelialtissueformed with the normal thickness. In contrast,abundant inflammatory cels and thinner epithelial tissues appeared in the control group. To conclude,bothnano-celulose protein and acelular matrix can accelerate wound healing by promoting oral mucosal epithelial hyperplasia.

OBJECTIVETo observe the effects of electroacupuncture (EA) on cochlea morphology and expression of aquaporin 1 (AQP1) in guinea pigs with endolymphatic hydrops, so as to explore the possible mechanism of EA on endolymphatic hydrops.

METHODSForty guinea pigs were randomly divided into a blank group, a model group, a medication group and an EA group, 10 guinea pigs in each one. Model of endolymphatic hydrops was established by using intraperitoneal injection of aldosterone. Guinea pigs in the blank group and model group were treated with identical immobilization as EA group but no treatment was given; guinea pigs in the medication group were treated with intragastric administration of hydrochlorothiazide at a dose of 5 mg/kg, once a day for consecutive 10 days; guinea pigs in the EA group were treated with' EA at "Baihui" (GV 20) and "Tinggong"(SI 19), once a day for consecutive 10 days. The serum ionic concentration in each group was tested by turbidimetric method; hematoxylin-eosin staining was used to measure the severity of cochlea hydrops; immunohistochemical method was used to observe the expression of AQP1 in the cochlea.

RESULTS(1) There was no endolymphatic hydrops in the blank group, moderate-severe endolymphatic hydrops in the model group and slight endolymphatic hydrops in the EA group and medication group. (2) The concentration of K+ and Ca2+ in the EA group was higher than that in the model group and medication group (all P<0. 01); the concentration of Na+ was lower than that in the model group (P< 0. 01) but higher than that in the medication group (P<0. 01); the concentration of Cl- was higher than that in the medication group (P<0. 01), but not significantly different from the model group (P>0. 05). (3) The ratio of expression area of AQP1 in the model group was lower than that in the blank group (P<0. 01); the ratio of expression area of AQP1 in the EA group was higher than that in the model group (P<0. 01), and lower than that in the medication group without significant difference (P>0. 05).

CONCLUSIONEA could relieve the endolymphatic hydrops in guinea pigs; the mechanism is likely to be related with up-regulating the expression of AQP1 in cochlea and ion concentration might be an important factor involved.
