Objective To study bioactivity of microencapsulated peripheral nerve tissue after transplanted into abdominal cavity and analyze the in vivo time-effect relation. Methods Microencap-sulated peripheral nerve tissues were injected into the abdominal cavity of mice. Results Microencap-sulated peripheral nerve could remain intact six months after transplantation. The peripheral nerve cells survived, with normal proliferation function. Conclusions Microencapsulated peripheral nerve tissues can remain bioactivity at least six weeks in vivo. Improved technique of microencapsulation may prolong bioactivity of microencapsulated peripheral nerve tissues and accordingly promote nerve regeneration fol-lowing peripheral nerve injury.

Objective To propose the orientation,goals and some key issues for future research in the field of war wound/trauma through reviewing the updated literature.Methods The latest literature in the field of war wound/trauma were reviewed.Results The notion "medicine always be with soldiers" had been raised by America and the Europe military circles,with special emphasis on emergency techniques and equipments,which were used in the front of battle field.This forwarded the medical aids as quick as possible and the formation of medical rescue system without crack.Meanwhile,much attention had been paid to the pathogenesis and prevention of post-traumatic complications,wounding characteristics and mechanisms of high-tech new weapons,as well as repair and regeneration of injured tissues.In China,a great advances had been made in the filed of emergency rescue,shock resuscitation,complication treatment and wound repair.Conclusions During the coming "twelfth five-year program",the research standpoint is to meet the needs of Chinese troops to perform better in modern wars and non-military actions,and the aim is to significantly reduce the rate of mortality and disability of trauma as well as to improve the whole army's health.To fulfill this aim,a lot of work should be done to enhance the trauma emergency ability at the battle front,the organization and remedy ability at conditions of combined operations of armed forces,and the translational medical research for rescue of trauma,so as to unceasingly increase the medical service ability of our army to cope with secure threaten and to accomplish multiple military missions.

Objective To investigate the activity of gastrocnemius muscle after acellular nerve transplantation with microencapsulated peripheral nerve tissue to repair sciatic nerve gap in dogs. Methods Twelve dogs were selected and divided randomly into four groups with three in each. Both sciatic nerves of the dogs in group A were cut and chemically extracted to make acellular nerves. Acellular nerves were transplanted into the dogs of groups B and C to bridge 30 mm sciatic nerve gaps, and additionally microencapsulated peripheral nerve were added in group B. Autograft was used for repairing the defects in group D. The motor function of operated limbs were observed regularly after operation. Six months after operation, motor conduction velocity of the specimens of sciatic grafting nerve segment were observed, and the gastrocnemius muscle of both sides were obtained and performed succinic dehydrogenase (SDH), synaptophysin (SYP) and motor end plate histochemical staining, and sciatic nerve 1 cm from distal end stoma were obtained and underwent Masson, Luxol fast blue and NF200 staining. Results All the dogs in groups B, C and D were involved in the results analysis without loss. Image analysis indicated the optical density and the cross section area of gastrocnemius muscle, area and optical density of synaptophysin, area and optical density of motor end plate in group B showed statistically significant difference compared with those in group C, but no significant difference with those in group D. The results of motor function recovery of operated-limb, electrophysiological examination and morphologic observations of sciatic nerve were all consistent with the detections of gastrocnemius muscle. Conclusion The gastrocnemius muscle may be again innerved by nerve, and the muscle atrophy is significantly alleviated after acellular nerve transplantation with microencapsulated peripheral nerve tissue for repairing sciatic nerve gap. The regeneration of nerve was better after the combined transplantation than only acellular nerve transplantation, so the combination of acellular nerve and microencapsulated peripheral nerve tissue may be a useful substitute of autograft for nerve repair.

Objective To analyze the short term prognosis of very low birth weight (VLBW) infants. Methods The clinical data of VLBW infants who were hospitalized from December 2013 to December 2014 and followed up to 6 months of corrected age were retrospectively analyzed. Results A total of 230 VLBW infants were enrolled. Thirty infants (13.0%) died during hospitalization, 40 infants (17.4%) were given up the treatment, 60 infants (26.1%) were improved at discharge, and 100 infants (43.4%) were cured at discharge. In the 30 cases of death, causes of death were mainly neonatal respiratory distress syndrome (18 cases), pulmonary hemorrhage (5 cases), and sepsis (3 cases). In the 200 survived infants at discharge, at 6 months of corrected age of follow-up, 13 infants (6.5%) were lost to follow-up, and 54 infants (27.0%) died, among whom 40 infants died because of giving up therapeutic intervention due to economic factor or discharges without permission. At 1, 3, 6 month of follow-up, the length and weight of VLBW infants were gradually approaching normal, and, however, at 6 months of corrected age, the length and weight of VLBW infants were still obviously below the children’s growth standard. The length of VLBW infants was more deeply below the growth standard than the weight. In 109 infants who had fundus ophthalmoscope, 21 cases had retinopathy of prematurity (ROP) I, and 7 cases had ROP II. In 98 infants who had the hearing screening test, 5 cases failed in one ear and 11 cases failed in both ears. In 95 infants who had the head magnetic resonance imaging (MRI) examination, 10 cases had intracranial hemorrhage and 9 cases had premature brain injury. In 49 infants who completed the neonatal behavioral neurological assessment (NBNA) at corrected age of 42 weeks, the scores were all lower than 35. In 36 infants who were assessed by Gesell developmental scale at the 3 months of corrected age, 11 cases had mild developmental delay and 2 cases had moderate developmental delay. In 24 infants who were assessed at the 6 months corrected age, only 2 cases had mild developmental delay. VLBW infants had a rapid progress in social contact, social behavior, and gross motor movement. Conclusions Economic, neonatal respiratory distress syndrome, pulmonary hemorrhage, and sepsis are pivotal factors for the survival and quality of life of VLBW infants. The surviving VLBW infants have catch-up growth and development.

Ageing of population is now a phenomenon of the world and has considerable consequences for public services.Ageing is always accompanied with dysfunction of multiple organs,including hypothalamic-pituitaryadrenal axis.Here,we summarized alterations of hormone secretion of adrenal glands in the elderly and their relationships with Alzheimer' s disease.Moreover,we discussed characteristics of pheochromocytoma,primary aldosteronism,and Cushing's syndrome in the elderly.Lack of typical manifestations usually makes difficulty in diagnosis.
