· AIM: To evaluate the safety of eye anterior tissue when plasmin (Pm) and hyaluronidase (HS) are injected into pigs'vitreouses to induce posterior vitreous detachment(PVD).· METHODS: 15 pigs without ocular diseases were randomly assigned to groups A,B,C (5 in each group). For each pig, one eye was experimental, the other eye was control. The experimental eye received intravitreal injection with enzyme:group A: 50U(0.1mL) HS; group B: 0.5U(0.1mL) Pm; group C: 0.5U(0.05mL) Pm combined with 50U(0.05mL) HS; while the control eye received intravitreal injection with equivalent dose of balanced salt solution (BSS). Postoperative reactions in the eyes were carefully observed by clinical examinations such as slit-lamp microscopy and direct and indirect ophthalmoscopy and measurement of intraocular pressure (IOP). Eyeballs were extirpated 7 days after the operation and histological examination was carried out. The corneas and irises were observed under light microscope (LM). The epithelia of ciliary bodies and lens were studied with transmission electron microscope (TEM).· RESULTS: In all experimental eyes and control eyes of group A, B and C, histological examination showed: under LM ,the corneas and irises of experimental eyes had no histological abnormality in structure; Under TEM, epithelial cells of ciliary bodies and the lens were tightly arrayed with clear cellular boundaries, clear intracellular structure, intact cell membranes, and intact nuclei; There was no significant difference in the clinical examinations and in the change of IOP between preoperation and postoperation, between the experimental group and the control group.· CONCLUSION: With 0.5U Pm and HS 50U injected into pigs' vitreouses to induce PVD, alone or combined with two enzymes, evaluation revealed no evidence of toxicity on the eye anterior tissue. The dosage was proved to be safe for eye anterior tissue.

Dermatology is closely related to the health of officers and soldiers both in peace time and war time. Under special circumstances, skin diseases have a direct impact on efficiency and combat effectiveness of the military. Research work on fungal infections and psoriasis in the PLA has been playing a leading role domestically, as well as reaching international advanced standards. In the past 20 years, PLA dermatologists had been granted 32 second awards of Army Science and Technology Advancement Prize. Among them, the results of a series of research on fungal infections accomplished by the Second Military University was granted a second award of the State Science and Technology Advancement Prize. In the past 5 years, the team of dermatology profession has been growing rapidly in the PLA. Up to now, there are 6 departments with 11 tutors who are entitled to train postgraduate students seeking doctorate degree, and about 100 of them have succeeded in thesis defense and conferred the doctoral degree. However, at present, there are still many problems unsolved and further research is necessary. The most important task is, under the guide of bio-physic-social medical modality, various sophisticated technologies should be applied in basic research, prevention, diagnosis, treatment etc. in the field of dermatology, in order to assure the physical and psychological health of the servicemen.

Objective To investigate the osteoclast′s function levels in infants and toddlers and the relationship between the osteoclast function and sex,age,body length,body weight and body mass index(BMI).Methods Sixty-eight children(37 boys and 31 girls,aged from 1 to 36 months) were studied.All of the children were in good health.These children were divided as infants group and toddlers group according to their age.Just before the samples were collected,the children′s body weight,body length were measured and the BMI were calculated.Two biochemical markers,such as serum tartrate-resistant acid phosphatase 5b(TRAP5b) and urine deoxypyridinoline(DPD) were measured.Results The difference of serum TRAP5b concentration between infants and toddlers was significant at the level of P
