Objective: To know the occasion and how the military in-patients understood the contents of health education, to discuss how to conduct the health education pertinently and how to make the military in-patients master the information and skill to get well effectively in a short time. Methods: By referring to literature samples and the main contents of health education of sections in our hospital, we designed a questionnaire including the main contents of health education、the fashion and the occasion of conduction in different phase of hospitalization, together with three subjects and 44 items, and we investigated 312 military in-patients in the way of questionnaire in combination of opening and closing. Results: Military in-patients considered the correlative knowledge of getting well as the shoe pinches of the main contents of health education. The communication between doctors、nurses and pation should be strengthened; Communication through talking and offering written materials were the two primary fashions of health education; The medical personnel and military in-patients disagreed in the time arranging of health education. Conclusion: We suggest the adoption of the educational method of ”advantage health education contents increased by degrees” to conduct health education; paramedic in all levels should pay attention to the feelings of military in patients, pay attention to the rational arrangement of the health education time and contents. We emphasize the training of paramedic's communication skills of talking and writing.

Objective:To study the pharmacokinetics and relative bioavailability of isosorbide 5 mononitrate(5 ISMN)sustained release capsules in 12 male healthy volunteers. Methods: A capillary gas chromatography method with electron captured detector was established for the determination of 5 ISMN in plasma, after administrating a daily dose of 40 mg 5 ISMN domestic and imported sustained release capsules in a randomized crossover design.The fluctuation of 5 ISMN valley concentrations observed and the steady state pharmacokinetics was characterized in a multiple dose schedule of 40 mg 5 ISMN sustained release capsules.Results:The steady state of 5 ISMN plasma concentrations reached at the fourth oral administration.The steady state pharmacokinetic parameters after multiple oral dose of 40 mg 5 ISMN domestic and imported sustained release capsules were as follows: t max were (4.8?0.6) and (4.8?0.9) h, c max were (802.46?94.45) and (807.09?109.16) ?g/L, c min were (127.83?23.76) and (121.85?22.00) ?g/L, AUC ss were (8 114.7?1 393.4) and (8 174.8?1 219.7) ?g?h/L, c av were (338.12?58.06) and (340.62?50.82) ?g/L,the degree of fluctuation (DF) were (2.04?0.39) and (2.03?0.33), respectively.

In view of the fact that medical inspection equipment sold in the domestic market is mainly imported from abroad and very expensive, we developed a full-automatic fluorescence analyzer in our center, presented in this paper. The present paper introduces the hardware architecture design of FPGA/DSP motion controlling card+PC+ STM32 embedded micro processing unit, software system based on C# multi thread, design and implementation of double-unit communication in detail. By simplifying the hardware structure, selecting hardware legitimately and adopting control system software to object-oriented technology, we have improved the precision and velocity of the control system significantly. Finally, the performance test showed that the control system could meet the needs of automated fluorescence analyzer on the functionality, performance and cost.

OBJECTIVETo investigate different treatment methods for stage-Is testicular mixed germ cell tumors (TMGCTs).

METHODSWe retrospectively analyzed the clinical data about 3'cases of stage-Is TMGCTs (aged 26-39 years) treated in the 175th Hospital of PLA, reviewed relevant literature, and explored the clinical characteristics of TMGCTs.

RESULTSOf the 3 patients, 1 was treated by radical orchiectomy, 1 by radical orchiectomy + retroperitoneal lymph node dissection + BEP chemotherapy scheme, and the other by radical orchiectomy + radiotherapy. The pathological components of TMGCTs were immature teratoma, seminoma, spermatocytoma, chorioepithelioma, embryonal carcinoma, and yolk sac tumor. No recurrence or distant metastasis was found during the 24-month follow-up after surgery.

CONCLUSIONThe diagnosis of TMGCTs primarily depends on physical examination, ultrasonography, MRI, and measurement of serum tumor markers, while its confirmation necessitates pathological examination, and its treatment is basically radical orchiectomy.

Objective　To compare the effects of mild hypothe rmic cardiopulmonary bypass (CPB) and moderate hypothermic cardiopulmonary bypas s in pediatric cardiac surgery. Methods　A total of 118 cas es of less than 3 years of age that had undergone open heart surgery were review ed, in which 46 patients received moderate hypothermic CPB(group 1) and 72 patie nts received mild hypothermic CPB(group 2). The CPB duration, incidence of low c ardiac output and postoperative concentration of CK-MK, etc, were compared with each other betwee n the two groups. Results　Duration of bypass and postoperative mechanical respiratory assistance of group 2 was shorter than that of group 1 ( P<0.05). Transfusion requirements, incidence of low cardiac output syndrome, concentration of CK-ME and percentage of metabolic acidosis were lower in grou p 2 than in group 1 (P<0.05), while the index of oxygenation was higher in g roup 2(P<0.05). Conclusion　The mild hypothermic CPB is saf er and more effective and therefore is superior to moderate hypothermic CPB in p ediatric cardiac surgery.

Objective To compare the sub-cellular proteome of isoniazid ( INH)-resistant Mycobacterium tuberculosis (MTB) with that of sensitive strains for identifying of unique proteins of these strains and discussing their preliminary application in clinical diagnosis. MethodsProteins of cell wall and membrane of 5 INH-resistant strains and 5 INH-sensitive strains were extracted by density gradient centrifugation.The extracts were subsequently analyzed using weak cation exchange (WCX) liquid chromatography ( LC )followed reverse phase (RP) liquid chromatography to compare the sub-cellular protein patterns. A total of 1280 fractions were collected and identified by matrix assisted laser desorption ionization-time of flight-tandem mass spectrometry (MALDI-TOF MS/MS). The Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for cell component and biological process analysis. Normalized Spectral Abundance Factors (NASF) was used for semi-quantity of protein expression. 5 proteins significantly up-regulated in INH-resistant strains and 2 proteins significantly up-regulated in INH-sensitive strains were selected for ELISA analysis with autologous sera respectively. Results A total of 347 proteins were identified. Cell component analysis showed that 58％ proteins were cells well or membrane proteins. Biological process analysis showed that 31％ proteins involved in carboxylic/monocarboxylic acid biosynthetic and metabolic process, 26％ and 15％ proteins involved in organic acid or fatty acid biosynthetic and metabolic process,while 28％ proteins involved in lipid biosynthetic , metabolic, transport and localization process. O-succinylbenzoate synthase, monooxygenase, hypothetical protein Rv2255c, nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase and membrane phosphatidate cytidylyltransferase cdsA were up-regulated in INH-resistant strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-sensitive sera. The differences between the INH-resistant sera and the INH-sensitive sera were significant ( t = 0.028, 0.044, 0.066, 0.064, 0.083, all P＜0.01 ). Chain A of Rv2002 Gene Product and Chain A of Crystal Structure Of Rv2632c were up-regulated in INH-sensitive strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-resistant sera. The differences between the INH-sensitive sera and the INH-resistant sera were significant (t=0.053, 0.073, both P＜0.05). ConclusionThe combination of density gradient centrifugation and 2D-LC MS/MS technology is useful in enrichment and identification of differential expressed proteins between INH-resistant and INH-sensitive strains at sub-cellular level. It is useful in finding antigens associated with INH-resistant MTB infection, which may prove useful for further study in the mechanism of INH resistant, as well as interaction between MTB and host.
