Objective: To study the critical influence factors in the preparation of orally disintegrating tablets of fresh antler with all ingredients (ODT-FA) by lyophilized method and to optimize the preparation technology. Methods: The lyophilized molding technology was used to prepare the ODT-FA and the optimal formulation and preparation were obtained by means of single factor test with promoting cell proliferation activity, moisture content, disintegration time, and appearance as evaluation criterion. Results: The optimal preparation conditions of ODT-FA were as follows: The frozen storage temperature of fresh antler was -40°C, acetate buffer was used as diluent to mix with the fresh antler powder according to ratio of 1:2, then to homogenize for 10 min under liquid nitrogen protection with 10% trehalose as lyoprotectant, and the homogenate was lyophilized in vacuum after poured into the mold to prepare the ODT-FA. The tablets could disintegrate within 30 s completely and its moisture content was less than 5%. In addition, there was no difference in promoting cell proliferation compared with fresh antler. Conclusion: The ODT-FA prepared by optimal technology has highly biological activity and is easy to take. The optimal preparation process is stable and suitable for industrial production.

Background Efficient and lowcost way to isolate keratocytes is helpful for research on cornea.Either relatively expensive or inefficient is the shortage of those means now applied,while raising the keratocytes through passage will change the phenotype of them quickly.Our aim is to approach the way getting keratocytes effectively utilizing modified two step enzymatic digestion by type I collagenase. Objective To evaluate the effect of isolating the bovine keratocytes utilizing two step enzymatic digestion and observe the morphological changes of the keratocytes during cultivation in vitro. Methods Keratocytes were isolated from bovine corneas using 0.5 mg/mL and 1 mg/mL type I collagenase digestion.The harvesting rate and viability rate of the primary keratocytes were evaluated.During the primary cultivation in vitro,the morphological changes of the keratocytes and their F-action distribution were observed.Results(1)The extracellular matrix of the bovine corneas were almost dissolved by the two step enzymatic digestion,followed the keratocytes completely isolated from the solid matrix.The amount of the harvested keratocytes from each cornea was(2.11±0.15)X106 on average while the viability rate was(91.69±3.73)% and the inoculation rate Was(81.20±1.25)%.(2)The primary keratocytes attached and spreaded out with dendritic and stellate morphology.After 3 days cultured,the branches of the keratocytes were contacting and formed networks.The F-actin detected by phalloidin binding showed a limited cortical localization. Conclusion (1)The method of two step enzymatic digestion can make the extracellular matrix of bovine cornea stroma completely degraded with the advantages in high efficiency of harvesting keratocytes and high cell viability and relatively simple manipulation. (2) The primary bovine keratocytes have dendritic morphology and with limited F-action distribute in cellular cortex.

· AIM: To investigate the role of intercellular adhesion molecule-1 (ICAM-1) in the graft rejection of rabbit penetrating keratoplasty (PKP).· METHODS: Sutures were used to produce corneal neovascularization (CNV) on New Zealand white rabbits to make PKP model. Graft mean survival time and rejection index were determined. The levels of sICAM-1 in serum and aqueous humor were dynamically determined by enzyme-linked immunosorbent assay (ELISA).Immunohistochemical technique was used on cornea to get the evidence of expression and distribution of ICAM-1.· RESULTS: Graft mean survival time is (12.4±1.3) days.The mean sICAM-1 levels in aqueous humor and serum in the control animals that did not undergo surgery were (16.6±3.6)ng/L and (95.2±6.3) ng/L respectively. Levels in aqueous humor and serum for the graft rejection group increased postoperatively, continued to increase to (53.9±19.2)ng/Land (378.8±30.6)ng/L, compared to those in the other group (P ＜0.01). ICAM-1 positive cells were found in the graft rejection group.· CONCLUSION: ICAM-1 plays a critical role in initiating and maintaining corneal graft rejection. Sequential determination of serum sICAM-1 after operation may be of value in the prediction and diagnosis of acute rejection.

OBJECTIVE To define the regularity of survival ability of HIV in natural environment,and prevent(infection) through contacting with positive body fluids during daily life or medical work.METHODS Having been diluted by sterile water or 10% serum RPMI 1640 medium,HIV was exposed to 4℃,room temperature(20-26℃) or 37℃ for different period of time.TCID_(50) of these samples was detected.Non-pathological samples were blind passaged for three generations.RESULTS HIV infective ability persisted more than 35 days both in(water) and medium at 4℃;whereas it persisted 7-14 days in water,14-21 days in medium at room temperature and 37℃.CONCLUSIONS HIV has higher resistance in natural environment.To prevent accidental spreading of HIV,HIV positive liquids and contaminants staffs should be treated carefully.

Objective To study the clinicopathological features and differential diagnosis of bizarre parosteal osteochondromatous proliferation (BPOP). Methods The clinicopathological features of 3 patients with BPOP were analyzed , and related literature was reviewed. Results 3 patients included 2 males and 1 female with an average age 40 years old (24-53 years old). The lesions in three patients were located in the left side of the distal radius, the left side of the little finger inside and the right side of ulna coracoid, respectively. Histologically, characterized by unusual mineralized cartilaginous matrix (`blue bone'), the lesion was composed of a heterogeneous mixture of bone, cartilage and fibrous tissue. Conclusion BPOP is a rare benign surface osteocartilaginous lesion, and its diagnosis and differential diagnosis mainly depend on radiographic and histopathologic features.

OBJECTIVETo evaluate the distribution and expression of peroxisome proliferator activated receptor gamma (PPAR-gamma) in human pituitary adenomas.

METHODSThirty eight consecutive surgically resected pituitary adenomas and 5 normal pituitary tissues were enrolled in the study. Immunohistochemistry was used to confirm the distribution of PPAR-gamma. Expression of PPAR-gamma was evaluated by Western blot.

RESULTSPPAR-gamma immunoreactivity was located in the nucleoli of pituitary adenoma cells. PPAR-gamma was expressed in all human pituitary adenomas and normal pituitary tissues. Its expression in pituitary adenomas was significantly higher than in normal pituitary tissues (P < 0.01), and its expression in ACTH-secreting adenomas was significantly higher than in any other type of pituitary adenomas (P < 0.05).

CONCLUSIONSPPAR-gamma may play an important role in the generation, growth, and invasion of human pituitary adenomas. It may become a novel therapeutic target for these tumors.

OBJECTIVETo study the marriage status, labour ability, income and other living condition of people affected by leprosy, and to provide information on prevention, cure and salvation programs from the government.

METHODSBased on the standardized national criteria and method, all registered people affected by leprosy in the whole province were asked to fill in a nationally standardized Form.

RESULTSOut of the 13,034 cases, 91.19% were farmers and only 13.01% of the teenagers were at school. On 12,816 patients at age for marriage, there were more unmarried males than females, more living in the leprosy villages than those living outside of the leprosy village (P < 0.01). Disability rate in leprosy villages was seen more than outside of the leprosy village. Per capita average annual income for the people affected by leprosy was only half of the average individual income in the whole province and 1/4 of the individual income in the nation.

CONCLUSIONThe living condition of those leprosy-affected people, particularly living in leprosy villages, called for special attention and the government should take comprehensive prevention to publicize the knowledge on leprosy to reduce fear and discrimination against them.
