Journal of Medical Postgraduates 2003;0(10):-
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. Conclusion:The relative bioavailability of multiple oral dose of 40 mg domestic 5 ISMN sustained release capsules is (99.07?5.45)%, there are no significant differences in the main steady state pharmacokinetic parameters between domestic and imported sustained release capsules, and so the 2 capsules are bioequivalent.

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 study the effects of compound preparation of Fanshiliu on lipid metabolism and pancreatic pathological changes in type 2 diabetes mellitus(T2DM)rats with insulin resistance. Methods:After fed with high-calorie food for 8 weeks,the rats received intraperitoneal injection with low dose of streptozotocin(STZ)to induce T2DM animal model,and then the rats were randomly divided into the model group,metformin group,high and low dose group of compound preparation of Fanshiliu. The normal group was given ordinary feed. The rats were sacrified after intragastric administration for six weeks,and fasted for 12 hours after the last administration. The lipid and lipoprotein indices were detected,and pathological morphology of pancreatic tissue was observed. Results:Compared with those in the model group,TC,TG,LDL-C and FFA in each treatment group were reduced,and HDL-C was increased(P < 0. 05). Fanshiliu high dose group and metformin group had obvious hypoglycemic and lipid-lowering effects. The results of pathological morphology of pancreatic tissue under a light microscope showed that the damage was the most obvious in the model group. Compound preparation of Fanshiliu groups and metformin group showed damage in varying degrees. Conclusion:Fanshiliu preparation can effectively adjust blood lipid levels,enhance the insulin sensitivity and reduce damage in pancreas in T2DM rats.

Relatively uniform-sized nanoparticles made of poly (lactic-co-glycolic acid) (PLGA) were prepared by premix membrane emulsification method. After the drug loading property was completed, the dynamic tissue distribution of nanoparticles was recorded. With the average particle size and span as indexes, membrane pore size, number of passing membrane times, membrane pressure, volume ratio of oil-water phase and the concentration of poly(vinyl alcohol) (PVA) in external water phase were investigated by single factor test, the optimum preparation technology of blank PLGA nanlparticles was as following: pore size of SPG membrane was 1 μm, membrane pressure was 1. 15 MPa, the number of passing membrane time was 3, the mass fraction of PVA of 2%, volume ratio of oil-water phase of 1 : 5. Prepared nanoparticles were round with smooth surface, the mean diameter was 332.6 nm, span was 0.010, the confocal laser scanning microscope (CLSM) concluded that fluorescent substance is uniform composizion in PLGA nanoparticle, and the in vivo imaging technology in mice include that the nanoparticles show good liver and spleen targeting property.
