Objective To analyze the characteristics and changes in the disease spectrum of Air Force(AF) servicemen in order to provide reference for the determinatron of the overall level of health of AF and priorities of disease prevention and control.Methods The data of outpatient and inpatient diseases between 2009 and 2013 in AF was collected and analyzed statistically according to the International Classification of Diseases-9(ICD-9),and statistical description was performed with SPSS18.0.Results Between 2009 and 2013,unit B had the highest number of outpatients and inpatients,accounting for 47.74% and 39.64% respectively.The upper respiratory tract infections,gastroenteritis/gastritis,chronic low back pain,skin diseases,nasal sinusitis,training injury,trauma,hemorrhoids,varicocele and stone diseases were the common and frequently occurring diseases in AF,which were the top ten in the disease spectrum.Among them,the incidence and admission rate of skin diseases kept declining.However,the incidence of gastroenteritis/gastritis in unit A,the incidence and admission rate of chronic low back pain in unit B and D,the incidence of injury in unit D,as well as the incidence of neurological headache and hypertension in unit C and D were higher than in other units.Conclusion Respiratory system disease,and occupation-related diseases such as low back pain,training injuries,trauma,skin disease and digestive system disease are the focus of health care in AF.Health education and health promotion for these diseases should be improved,and health intervention for key populations should be enhanced.

Objective To study the chemical constituents of Helicia nilagirica. Methods The ethanol extract was seperated by petroleum ether, dichloromethane, and n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical pro-(perties) and spectral analysis. Results Four compounds were isolated from the petroleum ether extract and identified as n-hexadecane acid (Ⅰ), ?-sitosterol (Ⅱ), ?-sitosterol-3-O-?-D-glucoside-6′-acetate (Ⅲ), and daucosterol (Ⅳ). Conclusion All the compounds are isolated from the plant for the first time. Compounds Ⅰ, Ⅲ, Ⅳ are isolated from the plants of Helicia Lour. for the first time, and compound Ⅲ is a new natural product.

Aim To establish a model of the vascular endothelial cell (VEC) injury in SDrats.Methods SD rats were randomly divided into the control and the modelgroups. The model rats were injected with adrenaline diluted to 2. 5 times 0. 05 mg?100 g-1 (tid) for 5 d continously. From the 4th d, they were irritated for 5 min in the0℃ cold-water in the middle between adrenaline injections.The control rats weregiven 0. 9% NS as above. At 6th d, blood samples were taken from carotid arteries ofthe rats and the CEC counts, t - PA、PAI activities, 6-keto-PGF1? concentrations andthe platelet aggregation rate(max) were detected respectively. Results In the modelgroup, as compared with those in the control group, t - PA activity and 6-keto-PGF1?concentration decreased significantly(P

Objective： The current study was designed to evaluate the treatment results of nasopharyngeal carcinoma by conformal radiotherapy. Methods： From September 1997 to February 2000, a total of 41 cases of recurrent nasopharyngeal carcinoma were treated by conformal radiotherapy. Among them, 27 cases were treated by late-course hypofraction conformal radiotherapy with the dose of 20- 24 Gy at 80％ isodose, 4- 7 Gy per time, following routine radiotherapy of 39 Gy/30f/3weeks. Fourteen cases received total-course conformal radiotherapy with the dose of 59.8 Gy/46f/4.6weeks at 90％ isodose. Results： The reference isodose curves conform to the target in three dimensions in conformal radiotherapy. The acute radiation mucositis, cranial nerve paralysis and trismus incidence were similar in two groups, however, in the hypofractionation group 22％ developed necrosis of nasopharyngeal mucosa, 3.7％ developed reduced optic nerve lesion, whereas none of the hyperfractionation group had these complications. The tumor response rate were both 93％ for two groups. Conclusion： Hyperfraction conformal radiotherapy is effective in the treatment of recurrent nasopharyngeal carcinoma and has relatively lower incidence of radiation complication.

OBJECTIVE: To investigate the personality and mental health of the objects of substance (caffeine, cocaine, hallucinogens and so on) abstinence who got labor education and rehabilitation. METHODS: 258 male objects and 250 female objects of substance abstinence selected randomly from institutions of labor education and rehabilitation were assessed with MMPI and SCL-90. RESULTS: MMPI tests indicated the personality abnormality in the objects. SCL-90 tests manifested the mental health abnormality of them compared with Chinese models, especially in the female objects. CONCLUSION More attention should be paid on the mental health of the objects of substance abstinence.

Objective To investigate the typical value of gamma-radiation dose rate and its confidence interval in tank-transported copper ore by using bootstrap resampling techniques. Methods Bootstrap resampling method, coupled with kernel density estimation, introduced to acquire the typical value of gamma-radiation dose rate in copper ore. Results The typical value of gamma-radiation dose rate in copper ore was expressed as the central tendency of the means of resampling, and two kinds of confidence interval, empirical percentile and bias-corrected accelerated confidence interval, were provided as standard error. Conclusion It is clearly demonstrated that this method has an advantage to give a robust description in explanation of central tendency and variation range of gamma-radiation dose rate data profiles.

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.

Objective To compare the effect of ultrasound-guided Mammotome minimally invasive operation and traditional surgery in treating benign breast tumor.Methods Eighty patients with benign breast tumor admitted to People's Hospital of Beijing Daxing District from October 2015 to April 2016 were randomly divided into group A and group B.Patients in group A accepted ultrasound-guided Mammotome minimally invasive operation (n =40),while patients in Group B accepted traditional surgery (n =40).Operation time,incision length,blood loss,patient satisfaction,postoperative pain,and the occurrence rates of complications were compared between the two groups.Results All the tumors in two groups were removed.Patients in group A had shorter operation time (10.4 ± 1.0) min,less blood loss (4.1 ± 0.5) ml,smaller length of incision (0.34 ± 0.04) cm (P ＜ 0.05 or P ＜ 0.01);also had less occurrence of complication (P ＜ 0.05);and patients in group A had better patient's satisfaction (95％) (P ＜ 0.01).Conclusions Ultrasound-guided Mammotome minimally invasive operation is helpful to shorten operation time and incision length,and reduce blood loss,also improve satisfaction.It is valuable for application and popularization in primary hospital.

AIM: To investigate the behaviour of 3T3 fibroblast and macrophage co-culture on blood fibrin clot or adipose tissue with recombinant basic fibroblast growth factor (rhbFGF). METHODS: MTT method, inverted contrast microscopy, Giemsa staining as well as scanning electron microscope were used in the present study. RESULTS: The effect of rhbFGF on co-culture of 3T3 fibroblast and mouse macrophage on blood fibrin clot in low-serum DMEM with rhbFGF were monitored, and 3T3 fibroblast and macrophage growed well on the blood fibrin blot in low-serum DMEM with rhbFGF. CONCLUSION: The blood fibrin clot, with its low immunogenicity, could be used as a bionic support for three-dimensional tissue culture, and also a physiological carrier to distribute the growth factor rhbFGF for the cells.
