Cone-beam computed tomography (CBCT) has an important function in understanding implant operations. CBCT can be used to evaluate the basic condition of implant site before implant operation and decide whether it is suitable for implanting. CBCT also ensures whether the direction of implant and the operation method are satisfactory. CBCT can be used pre- or post-operation as long as the case involves the maxillary sinus. Clinical implant cases using CBCT were introduced to evaluate the maxillary sinus pre- or post-operation.

Objective To evaluate MRI diagnostic accuracy and clinical value on the pancreatic carcinoma.Methods 79 patients with suspected pancreatic carcinoma were imaged by T1-weighted spin-echo pulse sequences and T2-weighted fast spin-echo pulse sequences in axial,sagittal and coronal planes with a pelvic phased-array coils.Results 43 patients were diagnosed as pancreatic carcinoma using MR imaging,in which 39 patients were proved pathologically by biopsy.Conclusion MRI is effective diagnostic modality in localizing and staging pancreatic carcinoma and guiding for the choice of pancreatic carcinoma treatment.

Parasitological and dissection methods were used to confirm Echinococcus infection and echinococcosis in animals,and to understand the epidemiological situation in final and intermediate animal hosts in Qinghai Province. Three Echinococcus species were found in the Province including E. granulosus,E. multilocularis and E. shiquicus. The prevalence of hydatid disease showed a tendency of increase with an average rate of over 50% in yaks and sheep. Higher prevalence in wild animals as intermediate host was found in the southern plateau,while that in final hosts such as dogs and wolves,the prevalence was higher in the area of Qilian mountain. There is a complex chain of life cycle of the parasites among animals,which poses a threat to the health of human population. Effective measures to control the disease in animals are urgently needed.

Objective: To screen high-affinity short peptides of the transforming growth factor beta typeⅡ(TGF-? Ⅱ) receptor from the phage display 12-mer peptide library.Methods: The recombinant solube human TGF-? Ⅱ receptor was used as the target to screen its affinity short peptides from the phage display 12-mer peptide library.The positive phage clones were obtained by 3 rounds of biopanning,followed by single stranded DNA extraction and sequence analysis.Results: Four nucleotide sequences were obtained from 10 positive phage clones with high-affinity TGF-? Ⅱ receptor.Neither conservative nor homologous sequence was found by sequence analysis compared with the transforming growth factor beta 1.Conclusion: Phage short peptides have been screened from the phage display library,which helps pave the ground for further researches on affinity short peptides and their role in inhibiting hepatic fibrosis.

Objective: To summarize the experience of the Chinese peacekeeping medical contingent in rotation after successful accomplishment of its peacekeeping mission.Methods: From December 2004 to July 2005,the Second Chinese Peacekeeping Medical Contingent was carrying out its peacekeeping medical support mission in West Africa.It successfully accomplished its mission entrusted by the United Nations,its long-distance intercontinental deployment and evacuation from the mission area,as well as its rotation by two-batch-mode handovers in an organizational system.Results: Smooth rotation ensured the fulfillment of the medical support mission,harmonious relationship with various units,close cooperation with related sections,joint action with multination forces and uninterrupted work performance.It tested the contingent's combat readiness and medical support ability.Conclusion: The rotation of the Untied Nations peacekeeping medical support forces provided an all-round training for the Chinese medical contingent and helped it adapt to the future warfare in the international setting,which is of great practical significance for strengthening military preparedness of the army.

The objective of this paper is to build a real-time and highly efficient platform for medical information in wartime.The different characteristics of the wartime medical information are analyzed.Based on the hospital information system,and centering on rescue timeliness,continuity,and quality as well as the coordination of medical service command,a wartime medical information platform is designed,which is significant to the medical work in wartime.

Objective To study the clinical features of meniscal cyst of the knee. Methods From January 2001 to December 2007,totally 5986 cases of meniscus operation were performed in our hospital,104 of them were diagnosed as having meniscal cyst in the knee. The clinical data of these patients,including gender and age distributions,causes and mechanism of injury,clinical presentations,characteristics of the cyst,and the type of the injury,were investigated. Results Incidence rate of meniscal cyst was 1.7% (104/5986) and the ratio between medial and lateral meniscal cysts was 1∶12 (8∶96). The mean age of the 104 patients was (30.7?12.2) years (range,13 to 65 years),and the radio of male to female was 1.2 to 1. Of the patients,60 cases (57.7%) had history of trauma,32 or them were hurt in sports,including football (11 cases),basketball (8 cases) and others. The most common primary symptom was pain (102 cases,98.1%),followed by swelling (50 cases,48.1%). Tenderness over the joint line (85 cases,81.7%) and palpable mass (79 cases,76.0%) with or without signs of meniscal tear were common presentations. The anterior and middle portions of the medial meniscus (5/8,62.5%),and posterior extension of the lateral meniscus (88/96,91.7%) were the most commonly involved sites (?2=15.167,P=0.000). The most frequently observed meniscal tear was a horizontal cleavage,alone (25/104,24.0%) or associated with another types of lesions (52/104,50.0%). In 5.8% (6/104) of the cases,the discoid meniscus was involved. Conclusions Meniscus cysts are unusual. The ratio between medial and lateral meniscal cysts favors the lateral meniscus. Meniscal tear and myxoid degeneration are the common causes of the cyst. The most frequently observed meniscal tear is a horizontal cleavage,and the anterior and middle portions of the medial meniscus and posterior extensions of the lateral meniscus are the most commonly involved sites.

Food allergy is a common allergic disease.The severity and incidence of food allergy reaction which increases gradually in recent years has seriously affected the healthy growth of infants and toddlers.Although the use of animal models to study the pathogenesis and prevention of food allergy has become the most important and common method because of the restrictions of clinical research,the international standard of food allergy model has not been established yet.Researchers often use milk,egg and peanuts which are very important food sources of infants and toddlers as allergens in animal models on the pathogenesis and control strategies.This article summarizes the research progress of animal models of milk,egg and peanuts,which will be helpful for researchers to choose animal model due to different purpose.

Objective To study the correlation between the change of plasma homocysteine (Hcy)and fibrinogen(Fib)levels with the disease condition and prognosis in the patients with cerebral infarction(CI).Methods The plasma levels of Hcy and Fib were detected in 250 cases of cerebral infarction and 100 healthy adults(normal control,NC).All patients were evaluated on 1 d af-ter admission by NHISS,and after the 6-month follow-up by the modified Rankin scale.Results The levels of plasma Hcy and Fib in the CI group were significantly higher than those in the NC group(P <0.05);the levels of plasma Hcy and Fib in the NHISS se-vere patients were higher than those in the moderate and mild patients (P <0.05);the levels of plasma Hcy and Fib in the moderate patients were significantly higher than those in the mild patients (P <0.05).The good prognosis rate the low Hcy and Fib group was significantly higher than that in high Hcy and Fib group (P <0.05).Conclusion The levels of plasma Hcy and Fib are signifi-cantly increased in the patients with CI,and the increase in the severe patients is more significant.The patients with increased plas-ma Hcy and Fib levels have relatively poor prognosis.
