5.ROENTGEN MANIFESTATIONS OF RADIATION INJURIES OF BONES:A CLINICAL AND RADIOLOGIC ANALYSIS OF 17 CASES
Medical Journal of Chinese People's Liberation Army 1981;0(04):-
Based on a clinical and radiological study of radiation injuries of the bones in the 17 cases, the relationship between the osseous changes and the radiation dosage and between the time from radiation therapy and the onset of the radiographic osseous changes were discussed. The authors found that the degree of local skin infection might determine the type of its underneath osseous injuries, i. e. being either "septic" (osteomyelitic) or "aseptic" (bone atrophic) radionecrosis, and it might also determine the time when the osseous changes appeared on the radiogram. It was found that radiation injuries of the bone could be distinguished from bone metastases. The authors suggest that a regular X-ray follow-up of the bones that had received a heavy dose of radiation should be made in order to reveal bone atrophy as early as posible and to remind the patient to avoid any trauma and infection.
6. Military tropical medicine in the 21st century
Academic Journal of Second Military Medical University 2010;31(6):581-584
Tropical medicine is defined by an association with geographic location, and it is a branch of medicine integrating preclinical medicine, clinical medicine and preventive medicine and investigating the diagnosis, treatment and prevention of diseases of tropical and subtropical zones. Military tropical medicine is a new interdiscipline based on tropical medicine and military medicine. With the improvement of health condition and the development of global economy, some tropical infectious diseases have been gradually controlled. However, factors such as increasingly frequent international communication and extreme changes in global climate induced by overproduction activity of human are leading to a redistribution of infectious diseases, which inevitably has impact on military strategies and tactics. This article reviews the past and prospect of military tropical medicine.
7. Infectious disease-related pathogens and their prevention and control strategies after earthquakes
Academic Journal of Second Military Medical University 2010;29(6):590-593
Epidemic diseases often occur following natural disasters, such as earthquakes. The most commonly seen epidemics after an earthquake include: enteric diseases (dysentery, typoid and paratypoid fever, cholera, hand foot-mouth disease, hepatitis A, hepatitis E, etc), arthropod-borne infectious diseases (malaria, Kala-Azar, Japanese encephalitis, etc), zoonosis (plague, hemorrhagic fever with renal syndrome, anthrax, etc), soil and epidemic water transmitted diseases (tetanus, gas gangrene, leptospirosis, etc), respiratory diseases (measles, rubella, influenza, etc), food-borne diseases (food poisoning caused by bacteria or bacterial toxin). This article reviews the controlling principles and measures for major infectious pathogens and epidemic diseases after earthquake.

Chinese Journal of Tissue Engineering Research 2016;20(25):3699-3705
BACKGROUND: Bone morphogenetic protein 2 possesses osteoinduction, and vascular endothelial growth factor plays a positive regulatory role in osteogenesis and bone repair. So what wil happen if both of them are used for spinal fusion? OBJECTIVE: To investigate the effects of fibrin glue combined with vascular endothelial growth factor 165 and recombinant human bone morphogenetic protein 2 on intertransverse process fusion. METHODS: Thirty Japanese white rabbits were randomized into three groups (n=10 per group): rabbits underwent intertransverse process fusion at the level of L5-6 with vascular endothelial growth factor 165/recombinant human bone morphogenetic protein 2/fibrin glue in experimental group, recombinant human bone morphogenetic protein 2/fibrin glue in control group, and fibrin glue in blank control group, respectively. At 6 weeks after implantation, observations of biomechanics, X-ray imaging and histology were performed. RESULTS AND CONCLUSION: Osteogenic fusion between transverse processes could be found in experimental and control groups except for the blank control group, which was better in the experimental group. The strength of osteogenic fusion in the experimental group was significantly stronger than that in the control group (P < 0.01). Besides, abundant chondrocytes, osteocytes, mature bone tissues and col agens could be found in the osteogenic fusion specimen of the experimental group, and numerous chondrocytes, osteocytes and mature bone tissues observed in the osteogenic fusion specimen of the control group. In conclusion, fibrin glue combined with vascular endothelial growth factor 165 and recombinant human bone morphogenetic protein 2 can promote osteogenic fusion.
