Objective To study the pattern of ultrasonic bone mineral density of calcaneus with age, height and body weight, and to establish a normal reference value of stiffness index (SI) of females in Southern China for providing scientific foundation for osteoporotic diagnosis and prevention. Methods SI for calcaneus in 2498 healthy people 10～87 years old was measured with Achilles Express ultrasound apparatus made in USA. They were divided into groups according to sex and age. One group for 10 years each and the records beyond 69 years were classified into one group, total 7 groups. Results The SI showed a characteristic mild rise-then-fall pattern with increasing age. And the peak value of SI presented in 20～29 age group. Pearson correlation analysis showed negative correlation between SI and age and a positive correlation between SI/ height and weight. The prevalence of osteoporosis gradually increase with age. Conclusion There are significant correlations in SI with age, height and weight; the values of SI will provide an important data reference to establish the normal values and diagnostic]standard of osteoporosis.

To explore the clinical manifestation of lymphomatoid granulomatosis (LG) and the early diagnosis. Retrospective analyses of the clinical features of LG and pathology features by open lung bio-psies were conducted. The patient was a 42-year-old female with irregular fever,and her chest X-ray and computed tomography showed nodules with cavity and pleural effusion. Open lung biopsy proved LG. LG is seldom seen in clinic. Open lung biopsy is very important for pathology diagnosis. Early diagnosis and treatment are the key to improving survival in these patients. The therapeutic effect is good.

Objective To study the effects of 4 1BBL on antitumor immunity induced in vivo by murine 4 1BBL gene transfected hepatocellular carcinoma cell line Hepa1 6. Methods Eukaryotic expression vector pcDNA3 1(+) m4 1BBL was transfered into murine hepatocellular carcinoma cell line Hepa1 6 via lipofectamine method. The transfected cells were selected in RPMI1640 containing G418(400～800 ?g/ml) and termed as Hepa1 6 m4 1BBL.The TCV m4 1BBL was obtained by treating with mitomycin (MMC). Three models (immunological model, early model, and later model) were established for the study of anticancer effects of TCV m4 1BBL. Results The syngeneic mice were completely protected and could survive free from tumor for a long period by inoculation with TCV 4 1BBL. In early models, TCV 4 1BBL showed strong immunotherapy effects( P 0 05). Conclusion The antitumor effect against syngeneic murine hepatocellular carcinoma cell line in vivo is significantly enhanced by the treatment with TCV 4-1BBL.

Objective To discuss the relationship between TCM syndromes and peritoneal fluid cytokine IL-6, IL-8 and TNF-α of endometriosis infertility patients, and provide thoughts for clinical treatment. Methods Totally 105 patients of endometriosis infertility were differentiated to six syndrome groups, including kidney deficiency and blood stasis, qi stagnation and blood stasis, heat stagnation and blood stasis, cold congelation and blood stasis, qi deficiency and blood stasis, phlegm-dampness stagnation. Thirty patients of non-endometriosis infertility were selected as control group. Enzyme-linked immunosorbent assay was used to detect cytokine levels of IL-6, IL-8 and TNF-α. Results In 105 cases of EM infertility, 35 cases (33.33%) were syndrome of kidney deficiency and blood stasis, 22 cases (20.95%) were syndrome of cold congelation and blood stasis, 18 cases (17.14%) were syndrome of qi stagnation and blood stasis, 10 cases (9.52%) were syndrome of heat stagnation and blood stasis, 11 cases (10.48%) were syndrome of qi deficiency and blood stasis, 9 cases (8.57%) were phlegm-dampness stagnation syndrome. The levels of IL-6, IL-8 and TNF-αin each syndrome group of EM infertility were higher than control group (P<0.01). IL-6 level in kidney deficiency and blood stasis group were higher than other syndrome groups (P<0.05). The levels of IL-8 and TNF-α in kidney deficiency and blood stasis group, and heat stagnation and blood stasis group were higher than other syndrome groups (P<0.05). IL-8 in kidney deficiency and blood stasis group was higher than that in heat stagnation and blood stasis group (P<0.05). Conclusion TCM syndromes in patients with endometriosis infertility have some relevance with peritoneal fluid cytokine levels of IL-6, IL-8, TNF-α, which may guide clinical understanding and treatment of endometriosis infertility.
