To explore the effects of the psychological behavior training on the recruits' physical performance. A total of 380 recruits selected from the Department of General Staff and missile troops were divided into experimental group and control group. The recruits of the experimental group undertook psychological behavior training before athletic exercises, including 3 000-meter running, grenade throwing, and push-up. The scores of these athletic exercises were compared between recruits of two groups. The results showed that the performance was improved in all the recruits, but the recruits of the experimental group made even greater improvement. The differences were statistically significant (P

Sensitivity toward pictorial sexual information was tested implicitly in 448 servicemen from four different arm services and 86 civilians. 20 pairs of pictures containing sex information for sensitivity test were screened out in prior-experiment, and then they were exposed to the test subjects with a 500 ms duration, in order to find out the difference in the subjects' preference in selecting sexual and non-sexual information pictures. The result showed that, compared with the civilians, all the four groups of servicemen showed stronger inclination in selection of sexual information pictures, however there was no group difference or gender difference. The results also suggested that, implicit experiment with paired pictures could be one kind of reliable and effective method in studying sex information sensitivity.

In order to study the mental health status of military personnel under settings of special military operations, 1 263 officers and crew of a submarine base, 361 officers and crew of a naval base and 753 officers and soldiers of a missile base were subjected to SCL-90 scale evaluation. The results were compared with mililary norms and civilian norms. It was revealed that SCL-90 of all the members of three groups had higher scores on every factor compared with the eivilion norms. Besides somatic factors, the scores of other factors were also higher than that of military norms. The results suggested that certain special military operation settings could exert negative impact on the mental health status of military personnel. An analysis of the results also showed that the greatest impact was found in submarine and naval officers and crew, as well as in missile troops, indicating that highly enclosed settings could strongly influence the mental health of individuals.

The psychological quality of military personnel is an important research topic in military psychology. The present rating scale for psychological quality of military personnel consisted of 30 items, and with this scale 94 military officers of 3 different rank groups were subjected to the test. 18 items were screened out as the items concerning basic psychological quality of military personnel according to the following two criteria: (1) more than 80% of the officers selected this item; (2) the mean score of the item was more than 1.00. Analysis of the results showed that, the connotation and denotation of the psychological quality of military personnel were in a certain degree similar to that of the general definition, and they also represented some special characteristics required by military settings. This study suggested that these 18 items reflected the basic elements of structural extension of the psychological quality of military personnel.

Objective To establish a method for fingerprint analysis of amino acids from honey by high performance liquid chromatography ( HPLC). Methods Amino acids of honey were concentrated by 732 cation exchange resin, and then were treated by pre-column derivatization with phenyl isothiocyanate, with praline as control peak. The chromatography was performed on a Waters Symmetry C18 ( 250 mm × 4.6 mm × 5 μm) column, with acetonitrile ∶ water (4∶1) as mobile phase A and 30 mmol/L sodium acetate ∶ acetonitrile (355∶15, acetic acid adjusting pH value to be 6.5) as mobile phase B by gradient elution. The detection wave length was set at 254 nm. The flow rate was 1.0 mL/min. The column temperature was 40℃, and the injection volume was 5μL. Results Sixteen common peaks were shown in the fingerprint of 15 batches of honey samples. The similarity for 15 batches of honey samples was in the range of 0.910 ~ 0.996 . Conclusion The fingerprint detection method is simple, practical, reproducible and specific, and can provide certain reference for quality control of honey.

Objective To evaluate the quality of different parts of agarwood formed by stimulation with biological induction method, thus to provide evidence for agarwood quality control. Methods The identification of agarwood and the determination of alcohol extracts from agarwood were achieved by the methods of Chinese Pharmacopeia. The determination of total chromones from agarwood was achieved by ultraviolet spectrophotometry(UVS), with aquilarone E as reference substance and 760 nm as the detective wavelength. Results The UVS method was stable within 5 h and the recovery rate was 95.71%(sR=2.09%). The average alcohol extract content of the outside part of the xylem of Aquilaria sinensis(Lour.) Gilg(part B) was 109.4 mg/g,which was higher than that (100 mg/g) of the Chinese Pharmacopoeia standard. The average content of total chromones was 15.73 mg/g. The rest identification results were accorded with the requirements of Chinese Pharmacopeia. The average alcohol extract content of the inside part of the xylem(part Z) was 47.6 mg/g, and the average content of total chromones was 2.66 mg/g. The rest identification results did not reach the requirements of Chinese Pharmacopeia. Conclusion The obtained part B of the agarwood meets the requirements of Chinese Pharmacopeia, while part Z has color changed and its quality has not yet reached the requirements. The results indicated that the biological induction method impacts Aquilaria sinensis xylem from outside to inside, and then the xylem grows into agarwood gradually.

BACKGROUND:Chitosan is a kind of natural biomaterial and is characterized by great biocompatibility, progressive degeneration and absorption and excellent mechanical property; however, whether it may become an ideal cytoskeleton in the engineering of cartilage tissue or not should be researched further.OBJECTIVE: To observe the hydrophilicity and adsorptivity to human nasal septum chondrocytes and the effect of its function of a novel scaffold made by [poly (dl-lactide-co-glycolide)] (PLGA)/chitosan nonwoven cloth embedded with lecithin (LEC) and poly-L-lysine (PLYS).DESIGN: Blank control study.SETTING: Department of Otolaryngology-Head and Neck Surgery, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA.MATERIALS: The experiment was carried out in the Department of Otolaryngology-Head and Neck Surgery, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA from October 2005 to June 2006. Chitosan nonwoven cloth was provided by Hainan Xinlong Company. The mainly technical parameters were detailed as the follows: degree of deacetylation ≥ 90% and relative molecular weight 2-5 × 105. PLGA/chitosan nonwoven cloth scaffold was made in Department of Otolaryngology-Hean and Neck Surgery, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA and High Polymer Institute of Sun Yat-sen University. The mainly technical parameters were detailed as the follows: mole ratio between monome lactide and glycolide 75:25, porosity 82%-86%, pore diamater 100-300 μm, shear strength 48 MPa, depth 1.5 mm and completely degenerated duration 14-18 weeks. Human nasal septum chondrocytes were the septal cartilage of nose which was derived from operated patients with deflection of nasal septum under sterile condition.METHODS: PLGA/chitosan nonwoven cloth was sheared into pieces with the size of 1.5 cm × 1.5 cm, dipped in 0.01 volume fraction of LEC anhydrous alcohol and 1 g/L PLYS for 6 hours, dealt with ultraviolet radiation after dehydration for 1hour, dipped in 0.75 volume fraction of ethanol for 24 hours, washed with Hanks solution, and incubated for 24 hours. After operations mentioned above, two kinds of novel scaffolds containing various components were obtained, and they were simple scaffold and scaffold embedded with LEC and PLYS. Cells derived from the third generation of human nasal septum chondrocytes were used to make suspension. In addition, cell suspension was grown on those two scaffolds to determine the degree of hydrophilicity through observing diffused degree of cell suspension. Whether cell suspension of human nasal septum chondrocytes was wafted on scaffolds or not were observed under phase contrast microscope so as to determine adsorptivity between cells and scaffolds; meanwhile, growth of cells and production of matrix were also observed.MAIN OUTCOME MEASURES: ① Hydrophilicity of those two kinds of scaffolds (diffused degree of cell suspension of human nasal septum chondrocytes on scaffold) and adsorptivity to cells (whether cell suspension of human nasal septum chondrocytes was wafted on scaffolds or not); ② growth of cells and production of matrix.RESULTS: ① When simple scaffold was put in cell suspension of human nasal septum chondrocytes, cell suspension showing like balls attached to the surface of scaffold, and then, scattered into space of scaffold gradually. During the period of culture, phase contrast microscope indicated that masses of cells attached to the surface of fiber of scaffold.When the petri dish was shaken, cell groups drifted irregularly. The adherent rate was (21±3.7)%. With the cultured time passing by, matrix was not produced. ② When scaffold embedded with LEC and PLYS was put in cell suspension of human nasal septum chondrocytes, cell suspension scattered into space of scaffold rapidly. The adherent rate was (89±5.6)%, which was higher than that of single scaffold group. This suggested that scaffold showed a strong hydrophilicity.Phase contrast microscope indicated that chondrocytes as the form of monome or community were distributed between scaffold and fiber averagely and attached to the surface of fiber of scaffold. When the petri dish was shaken, cell groups did not drift irregularly, and only a few of cells were scarred at the bottom of petri dish. This suggested that scaffold had a strong adsorptivity to cells. One week after culture, matrix showing like cobweb was produced among fibers of scaffold.With the cultured time passing by, matrix was produced abundantly.CONCLUSION: The novel scaffold of PLGA/chitosan nonwoven cloth embedded with LEC and PLYS is characterized by an excellent hydrophilicity and adsorptivity to human nasal septum chondrocytes; meanwhile, it also can secrete matrix.
