Aerospace nutrition and food hygiene is a subject elucidating the effect of aerospace envi-ronment on nutrition and food hygiene which is closely related to health of flight personnel. The teaching work should be in the aim of raising battle effectiveness and enforcing the primary professional capability of students. The most required theory and techniques in both peacetime and wartime was the priority of teach-ing fulfilling mainly through practical or in-site learning. The examination was composed of test paper, ex-periments and health propaganda. The teaching evaluation relied on feed-back of the army on which the teaching plan was revised. Survey in three straight years indicated the exploration enhanced teaching quality significantly.

Objective To investigate the expression and clinical significance of migration inhibitory factor ( MIF) and matrix metalloproteinase-9(MMP-9) in human gastric cancer tissue and corresponding adjacent normal tissue. Methods Selected surgery and pathologically confirmed 80 cases of gastric cancer as the experimental group, took another 80 cases of corresponding adjacent tissues as a control group. The expressions of MIF and MMP-9 were de-tected in 80 cases of gastric cancer patients cancer tissue and corresponding adjacent normal tissue by immunohisto-chemical SP method. Results ①The expression of MIF and MMP-9 of gastric cancer in varying degrees:The pos-itive rates of MIF and MMP-9 were 68. 8% and 67. 5%,which were higher than that in adjacent normal tissues, 32. 5% and 37.5% (P <0.05);② The expression of MIF was significantly associated with the clinical stage, depth of invasion,degree of differentiation,lymph node metastasis and TNM staging (P<0.05), nothing to do with other clinicopathological parameters;the expression of MMP-9 was significantly associated with the depth of inva-sion,degree of differentiation, lymph node metastasis and TNM staging (P<0.05), nothing to do with other clini-copathological parameters;③ There was positive correlation between the expression of MIF and MMP-9 in gastric cancer tissue (χ2 =9. 154, P<0. 01,r=0.338). Conclusion The expressions of MIF and MMP-9 show a posi-tive expression in gastric carcinoma, there maybe have a positive correlation between MIF and MMP-9. Their ex-pressions of varying degrees are closely related with the occurrence and development of gastric cancer, guidance gastric diagnosis, treatment and prognosis.

Objective To evaluate the susceptibility to toenail fungal infection (FI) in the elderly. Methods Two hundred patients with toenail FI aged 60 years or older from 2005 to 2007 in our hospital were collected in our study, including one hundred elderly patients with toenail fungal infection (case group) and one hundred elderly patients without toenail fungal infection (control group). The clinical data of the patients in two groups were analysed. Results In case group, diabetes mellitus was the most common complication, accounting for 24% (24/100), while there were only 6 cases with diabetes mellitus (6%) in control group (P<0. 05). In case versus control group, there were 31 cases vs 12 cases with lower extremity varicose vein (P<0. 05), and 36 cases vs 19 cases with foot deformity, 11 cases vs 3 cases with toenail onychomychosis following trauma of their toes (P<0.05) ,32 cases vs 12 cases with history of wearing tight shoes (P<0. 05). In case group, 12 of 47 female patients used to wear high-heel shoes. Conclusions Toenail trauma, foot malformation, lower extremity varicose vein and diabetes mellitus are predisposing factors for toenail onychomycosis in the elderly.

We retrospectively reviewed the clinical data of 826 cases with vitiligo treated in Beijing Hospital from 1998 to 2008. Most of patients present vitiligo in early age;20. 6% patients had positive family history. There were 44. 12 %, 41.18% and 10. 00 % of patients with vitiligo in their first, second and third degree relatives, respectively. Patients with family history had an earlier onset than those without a family history ( t = 1.97, P < 0. 05 ). Vitiligo vulgaris was found in 91.40 % patients. The most common affected site was head and face (31.5%) ;8. 1% of the patients was associated with other autoimmune diseases, including thyroid diseases, diabetes. There were more females than males in patients aged below 14. The child patients were more likely to present with Koebner' sign and halo nevus than the elder ones (P<0.05).

The volatile oil is the main component in the leaves of Perilla frutescens. According to the main types of monoterpenoids or aromatic compounds, it can be divided into different chemotypes and the main chemotypes of Chinese producing Perilla are PA type (mainly containing Perilla aldehyde and limonene), PK type (mainly containing perillaketone) and PP type (subdivided as PP-a type, with apiole as its main component; PP-m type, with myristicin as its main component; PP-e type, with elemicin as main component; PP-as type, with asarone as main component). Based on the biosynthetic pathways analysis, we also found that the formation of the particular chemotype is usually controlled by a single gene or a few genes, and different types have different pharmacological effects. In this paper, the classification under the species P. frutescens, main chemotypes of the volatile oil, and their biogenesis and regulation, pharmacological effect and influence factors are summarized and reviewed.

Objective To analyze the clinical diagnosis and therapeutic effect of primary middle lobe lung cancer,in order to provide evidence for clinical diagnosis and treatment.Methods The clinical data of 45 cases of primary middle lobe lung cancer treated by surgery from January 2002 to January 2007 were ana- lyzed retrospectively.The operation style includes:simple middle lobectomy 12 cases(26.7 %),middle or up- per lobectomy 10 cases(22.2 %),right lung total resection 5 cases(11.1%).Chest exploration was done on 2 cases(4.44 %),palliative resection or vedged resection 2 cases(4.44 %).Results 1 case died from lung in- fection and respiratory failure(2.22 %).15 cases with arrhythmia (33.3 %), 1 case with chylothorax were cured after conservative treatment.The survival rate of 1,3,5 year were 82.1%,64.3 %,32.1% respectively. Conclusion The treatment of primary middle lobe lung cancer is dominated by regular lobectomy. It is difficult to perform middle lobectomy,so double or total lobectomy is done generally.Owing to the more postoperative complications, it should be cautious to perform sleeve resection.It should be avoided to do vedged resection for primary middle lobe lung cancer in order to lessen local recurrence.

Using site-directed mutagenesis and DNA recombinant technology, GGC fragment was inserted into human IL-18 cDNA. The mutated IL-18 cDNA was constructed into plasmid pPIC9K, then transformed into Pichia pastoris GS115 and efficiently expressed. A Glycine residue was inserted into the recombinant IL-18 between Arg39 and Asp40 to form a RGD motif. The mutated IL-18 was termed IL-18-RGD. The protein was purified with Sephadex G-100. The cell culture of melanoma B16 showed that IL-18-RGD efficiently inhibited B16 tumor growth, IC50 = 8.10?mol/L, but the inhibitory effect of IL-18 was not detected. Both IL-18-RGD and IL-18 showed inhibitory activities on mice loaded B16 in vivo, the inhibitory efffct of IL-18-RGD was stronger than that of IL-18. The inhibitory activities of IL-18-RGD and IL-18 on bFGF induced angiogenesis on chorioallantoic membranes were detected. There was no differences between IL-18-RGD and wild IL-18 in the activity of inducing IFN-? in human PBMC.
