Osteoporotic fracture is the most destructive ending of osteoporosis, many interacting risk factors play a role in its occurrence. With age, the bodies function decline gradually. Symptoms like soreness of the waist, back pain, cramp of the lower limb and weakness appears. These are related to TCM syndrome factors like kidney deficiency, liver deficiency, spleen deficiency and blood stagnation. Symptoms can act as a warning of the occurrence of osteoporotic fracture in the early stages. The risk assessment tool of osteoporotic fracture is mostly developed on the basis of modern risk factors and thus lacks syndrome differentiation, that may limit its utilization. If the relevant content of syndrome differentiation is integrated into the forecasting tool and a risk assessment tool of osteoporotic fracture which complies with the demographics of China is built up, population risk assessment for high of risk could be established and scientific evidence for the adoption of effective interventions could be applied.

AIM: To evaluate the effect of staphylococcal enterotoxin B (SEB) or staphylococcal enterotoxin C (SEC) combining with dendritic cells (DC) on T cell functions and in vitro anti-HcaF tumor cytotoxicity of activated T cells. METHODS: S-100 protein expression in DC was detected by immune histochemistry staining. The expressions of I-E~? and CD80 molecules on DC, the expression of CD69 molecule on T cells and the production of IL-2 and TNF-? by T cells were determined with flow cytometry. The proliferation of T cells and its cytotoxicity to HcaF tumor cells were detected by MTT assay. RESULTS: In vitro experiments showed that isolated DC expressed high level of S-100 protein. SEB or SEC-induced DC highly expressed I-E~? and CD80 molecules and that SEB or SEC-induced DC promoted the activation and proliferation of T cells. 100 ?g/L of SEB or SEC was the most effective concentrations to induce T cells to secret IL-2 and TNF-?. The T cells activated by SEB or SEC combined with DC showed significant cytotoxicity to HcaF cells, appearing a stronger role than tumor antigen combined with DC. There was no difference in the role for T lymphocytes between both SEB and SEC. CONCLUSIONS: The results indicate that SEB or SEC combined with DC is an effective way to enhance T cell functions, producing stronger cytotoxicity to HcaF tumor cells than tumor antigen-loaded DC used at present, which offers a forceful evidence for the possibility of superantigen SEB or SEC combining with DC to be applied to clinical tumor immunotherapy.

Objective To observe and compare the clinical characteristics of colorectal related multiple primary carcinoma (MPC) and colorectal carcinoma (CRC) for promoting early diagnosis and treatment of colorectal related MPC. Methods Pathological and clinical documents of clearly staged CRC and colorectal related MPC cases from Jul. 1997 to Nov. 2007 were retrospectively analyzed. Results 573 colorectal carcinoma cases were analyzed, including 45 MPC (7.85 %). Parenteral multiple carcinoma originated most frequently from stomach, and then breast, ovary, lung, small intestine and other sites. Among all multiple primary colorectal carcinomas (MPCC), ascending colon carcinoma was most frequent (34.0 %).While among CRC cases, rectal cancer cases was most frequent(36.5 %). Comparing CRC and MPCC, there were no significant difference in terms of tumor family history. Median morbidity age was 57 years and 63 years respectively. Cases with previous colonic polyps accounted for 20.0 % of all MPC cases, while only 0.9 % of all CRC cases. The mOS of CRC and MPC was 93.7 month and 64.8 month respectively. Most frequent pathological type of CRC and MPC were both well-moderately differentiated adenocarcinoma, but more mucinous adenocarcinoma cases were observed in MPC. Conclusion Colorectal related MPC are relatively common among colorectal carcinoma patients. More patients with MPC especially MPCC has colonic polyp. mOS of MPC is shorter than that of CRC, indicating the poor prognosis of MPC compared with CRC.MPCC has multiple colonic polyps, shorter interval of secondary carcinomas, and shorter mOS, worse prognosis than MPC with parenteral tumor.

The study showed that the L-argmine-adsorbing capacity of strong-acidic resin 001?7 was 1.135 meq per ml of wet resin by controlling the flow rate of the broth at 1/52 vvm, and the efficiency of the elution was higher by using ammnia water as an eluent at the flow rate of 1/50 vvm. About 160 ml of the above eluant was decolorized with 10 ml of 201?4 resin, the transparance of the decolorized eluant was over 90%, and no adsorption of L-arginine by the 201?4 resin was observed. Under the controlled conditions, the extraction yield of L-arginine reached over 95%.

Objective To establish a stable cell line secreting human IgE Cε2-4 protein, and in-vestigate the binding capacity of receptor FcεR Ⅰ Methods The E24 gene was derived from SKO-O07 cell line, and was then cloned into pcDNA3.1 (+) (signal peptides were synthesized and fused at the 5'-end of E24 gene) or pCMV-L vector. After transient transfection into 293T cell, the secreted F24 protein was ana-lyzed by sandwich ELISA. The best vector was chosen to be transfected into CHO cells with LipofectAMI-NETM 2000 reagent. After being selected by G418 and subcloned three times by limited-dilution method, two stable cell lines were established. E24 gene was amplified by RT-PCR, and the E24 protein in the superna-tant was identified by ELISA. Besides, the binding capacity of FceR ⅠⅡ was analyzed by flow cytometry method. Results Three mammalian expression vector SP-E24-F3. 1, SP lI-E24-P3.1 and E24-PL were constructed and transient transfected to 293T cells. The output of E24 protein in the supernatant were 19.1, 19.4 and 8.7 μg/ml, respectively. Then the vector SP IX-E24-P3.1 was transfected into CHO cells. Final-ly, two single clones secreting E24 protein were stably obtained. The output of E24 were all at least 25 μg/ml. RT-PCR could detect the E24 gene from one of the two clones. Furthermore, flow cytometry results showed that E24 could bind the receptor in a dose-dependent manner. Conclusion Two stable cell line se- creting E24 protein were obtained, while E24 could specifically bind FcεR Ⅰ.

Objective To explore the effects of forepaw sensorimotor deprivation in early life on hippocampus-dependent spatial reference learning and memory in rats. Methods Newborn SD rats were randomly assigned to experiment group (deprivation of forepaw sensorimotor function, n=53) and control group(n=55). Rats of postnatal day 13 (PN13) in experiment group were seleeted, and models of forepaw sensorimotor deprivation were established by microsurgical technique. Open field tests and Morris water maze tests were performed during the time periods of PN25(PN21-31), PN35 (PN31-39), PN45(PN41-50) and PN60(PN56-64) to evaluate the locomotor activity and spatial reference learning and memory, respectively. Results In open field tests, there was no significant difference in parameters of locomotor activity and exploratory behavior between the two groups (P>0.05). In Morris water maze tests, eontrol group performed significantly better than experiment group during training sessions and probe tests on PN25 and PN35 (P<0.05). While on PN45, although there was no significant difference between the two groups during training sessions, control group performed significantly better than experiment group during probe tests (P<0.05). Conclusion The deprivation of forepaw sensorimotor in early life has no signifieant effect on the locomotor activity and exploratory behavior of rats, but can impair the spatial reference learning and memory.
