CCL21 is originally reported as a CC chemokine mainly expressed in secondary lymphoid tissues. CCL21 can dictate lymphocytes homing in the flow environment,where T cells use integrins stimulated by CCL21 to arrest on endothelial cells,and can act as a chemoattractant for T cells,B cells,mature dentritic cells and natural killer cells strongly. CCL21 can collect activated effector cells and keep them around the tumor. It is also a pivotal molecule for priming T cell responses. Therefore,CCL21 plays a potential role in anti-tumor therapy, and its high expression is responsible for many immune diseases.

The purpose of this review is to investigate the value of the calcification in differentiating malignant thyroid neoplasm and the molecular mechanisms for the formation of the calcification. Many published reports have proved the presence of calcifications in thyroid neoplasm and calcified nodules in these studies are more frequently malignant than noncalcified nodules. Through viewing the related references, we found that psammoma bodies (PBs), Runx2, osteocalcin, osteopontin, CD44v6 play an important role in the molecular mechanisms in the formation of the calcification in PTC. But further study is required for elucidating the mode of action.

Mass data is absent for the employment of the graduates in biomedical engineering specialty in China. Questionnaire was carried out in the graduates from 1989 to 2013 in School of Biological Sciences & Medical Engineering of Southeast University, and more than 1 500 questionnaires on the graduate employment were classified, summarized and analyzed to provide instructions for graduate employment guidance and student education in biomedical engineering specialty.

Acetazolamide, a sulfonamide-derived medication, is frequently used in the treatment of various types of glaucoma. But this kind of medicine is associated with acute angle closure glaucoma. This paper is a review for the researches of this rare adverse reaction at internal and abroad. It can prompt more ophthalmologists to understand and pay attention to this rare adverse reaction of acetazolamide and sulfonamides derived drugs. Then the doctor will make accurate diagnosis, timely treatment and grasp the right operation opportunity and reduce the occurrence of postoperative complications ultimately.

Objective: To study collagen distribution and its quantitative variation in t he aortic adventitia of spontaneously hypertensive rats Methods: Sirus red stain was used to observe collagen distribution in aortic adventitia；Chloramine-T oxidation assay was employed to quantitate the collagen of aortic adventitia；Immuno-histochemical staining was adopted to detect type Ⅰ、Ⅲ collagen synthetic characteristic of vascular adventitial fibroblasts. Results: Collagen of rat aoritc wall mainly distributes in adventitia；SHR shows more collagen deposition in adventitia than WKY at the age of 8weeks and 24 weeks；The immuno-histochemical staining of type Ⅰ、Ⅲ collagen in vascular a dventitial fibroblasts is positive. Conclusions: All those results indicate that vascular adventitia ma y be involved in hypertensive vascular remodeling.and vascular adventitial fibroblasts can synthe size collagen type Ⅰ and Ⅲ.

AIM:Effects of anatotensin Ⅱ on type Ⅰ collagen synthesis and its mRNA expansion in cultured vascular adventitial fibroblasts. METHODS: Vascular adventitial fibroblasts (VAF)were isolated, cultured from rat thoracic aorta by explant method. ELISA was used to study type Ⅰ collagen synthesis and competihve RT - PCR was employed to detect its mRNA expression after angiotensin Ⅱ administration. RESULTS: Angiontensin Ⅱ caused a dose dependent increase of type Ⅰ collagen synthesis and its mRN expression in VAF. CONCLUSION: The results support that angiotensin Ⅱ is an important factor controlling collagen metabolism of VAF and VAF may play an im- portant role in vascular remodelling of hypertension.

Two ent-kauranoids were isolated from the ethanol extraction of rhizomes of Canna generalis (Cannaceae), and were purified by various technologies, including silica gel and high performance liquid chromatography, and their structures were determined by modern spectroscopy techniques as (5R,8S,9S,10R,13R)-2-oxo-ent-kaur-15-en-17-oic acid (1) and (4R,5S,8S,9S,10S,13R)-19-hydroxy-ent-kaur-15-en-17-oic acid (2). Compound 1 is a new ent-kauranoid, and compound 2 is obtained from rhizomes of Canna generalis for the first time.

OBJECTIVE: Discuss the clinical features of primary ectopic thyroid carcinoma. METHOD: The clinical data of three cases diagnosed of primary ectopic thyroid carcinoma in our department since 1990 were analyzed ret respectively and related literature was reviewed. RESULT: All three patients were young females that had cervical lumps before surgery. The pathology results confirmed the diagnosis of ectopic thyroid papillary carcinoma. All cases had followed up till now and no relapse signs occurred. CONCLUSION Ectopic thyroid tissue is resulting from developmental defects at early stages of thyroid gland embryogenesis. They can cancerization, the treatment of ectopic thyroid carcinoma is also controversial. Here,we report 3 cases of primary ectopic thyroid papillary carcinoma, all of which were removed by surgery, take thyroxin orally after surgery and have a great prognosis.

The investigation on the chemical constituents of Anabasis aphylla L. was carried out by using various chromatographies, such as silica gel, Sephadex LH-20 and RP-C18 column chromatography. Further detailed investigation on the fraction of the ethanol extract of Anabasis aphylla L. yielded one new compound p-acetyl-phenol 1-O-beta-D-xylopyranosyl-(1-->2)-beta-D-glucopyranoside (1), together with five known compounds: piceine (2), isorhamnetin (3), quercetin (4), rutin (5) and isorhamnetin-3-rutinoside (6). Their structures were elucidated by spectral analysis such as NMR and MS. Among these compounds, compounds 2-6 were isolated from this plant for the first time.

Objective To evaluate the effect of ultra-filtration extract from Danggui Buxue Decoction (DBD) on immune function of H22 bearing mouse and explore the mechanism through observing the effect of ultra-filtration extract from DBD on the secretion of the cytokines (IL-2,IFN-?).Methods We used membrane separation technique to extract DBD.The content of IL-2 and IFN-? in splenocyte culture supernatant was detected by enzyme-linked immunosorbent assay (ELISA),and the mRNA expression of cytokines (IL-2,IFN-?) in splenocytes was assayed by reverse transcription-polymerase chain reaction ( RT-PCR).Results The content of IL-2 and IFN-? in splenocyte culture supernatant was increased in ultra-filtration extract from DBD groups,significantly in high-dose group (P
