Objective　To introduce the development of therapy of hilar cholangiocarcinoma. Methods　This summarization paper was made on the literatures review. Results　Extended radical resection, neoadjuvant chemotherapy, orthotopic liver transplantation, photodynamic therapy and molecular chemoradiotherapy might improve the survival rate. Conclusions　Surgical resection combined with other theraputic methods is the main treatment for hilar cholangiocarcinoma.

An embryo of 4.3 mm is described. It comes to the laboratory in 10 per cent for-malin as an intact chorion measuring 22 by 16 mm. The embryo is in the shape of theletter C, and its tail is curved. The limb buds are round in shape. There are 4pharyngeal pouches, the 4th being very small. Between the bases of the 1st and 2ndbranchial arches, in the floor of the pharynx, the tuberculum impar has developed. Theotic vesicles are slightly elongated sacs and no longer connected with the covering ecto-derm. The eyes are represented by the optic vesicles and the thickened ectodermal an-lage of the lens. Trachea is still largely a groove in the ventral wall of the pharynx andesophagus. The heart is still in the so-called S shaped stage; the atrium lies on the leftside of the bulb, and has not yet doubled; the sinus venosus is not completely out ofthe septum transversum; in the atrium, near the sinus venosus, the endothelial tube isclosely attached to the wall. There are 4 pairs of aortic arches: the lst pair breaks intocapillaries imbedded in the mandible. The other three join the dorsal aortae which runcaudal and finally unite to form one median dorsal aorta. The anterior cardinal, pos-terior cardinal, common cardinal and vitelline veins, etc. are all paired and symetricallyarranged. The embryo herein described falls in group Ⅷ of Streeter.

Objective:To explore influence of rehabilitation exercise on daily living capacity in aged patients with chronic heart failure (CHF) .Methods :A total of 60 aged CHF patients were randomly and equally divided into rou‐tine treatment group (received routine CHF treatment and nursingcare ) and rehabilitation exercise group (received rehabilitation exercise based on routine treatmentgroup ) .Brain natriuretic peptide (BNP) level ,left ventricular e‐jection fraction (LVEF) ,daily living capacity and 6min walking distance (6MWD) were measured and evaluated in both groups at hospitalization and six weeks after treatment .Results:After six‐month treatment ,BNP level signifi‐cantly reduced and LVEF significantly rose in both groups ,and there were significant rise in 6MWD and daily living score in rehabilitation exercise group ,P<0.05 or <0.01 ;compared with routine treatment group ,there was signif‐icant reduction in BNP level [ (525.3 ± 113.2) pg/ml vs .(252.2 ± 114.5) pg/ml] ,and significant rise in LVEF [ (43.46 ± 9.12)% vs .(47.24 ± 8.46)% ] ,6MWD [ (286.6 ± 46.2) mm vs .(582.5 ± 55.3) mm] and daily living score [ (65.12 ± 17.6) scores vs .(82 ± 14.8) scores] in rehabilitation exercise group , P<0.05 or <0.01. Conclu‐sion:Rehabilitation exercise can significantly improve heart function ,raise daily living capacity in aged patients with chronic heart disease .

Objective To observe the dynamic levels of IL-2,IL-5 and IL-6 produced by Balb/ c mice infected with DEN_2 clinical strains and to study their relation.Methods The Balb/c mouse in- feetion model was established by multiple-site subcutaneous injection with various doses of DEN_2 clini- cal strain.Mouse plasma samples collected from different experiment groups at various time after in fection were tested for IL-2,IL-5 and IL-6 levels with sandwich ELISA.Results After primary in- feeted with DEN_2 B strain,the levels of IL-2,IL-5 and IL-6 of all experimental groups were not sig- nificantly higher than the normal control group while the levels of experimental groups increased sig- nificantly after re-infection.The level of IL-2 reached to peak[average value of(101 522.44?10 465.375)pg/ml]at the 4th day after re-infection(the 20th day after the primary infection),and then the level gradually reduced.The levels of IL-5 in the Balb/c mice of the group 1 and 2 reached to peak at the 1st day after re infection(the 16th day after the primary infection),and there was signifi- cant difference between these two groups and the control group(P＜0.05).The levels of IL-6 in all experimental groups reached to peak at the 1st and the 2nd day after re-infection.The peak value of the third group is the highest comparing with the normal control group(P＜0.05).Conclusion Th2 response was predominant in the second infection phase.

Objective To study the diagnosis and indications of operation of thyroiditis associated with thyroid cancer(TTATC). Methods The clinical data of 16 patients with TTATC were analysed retrospectively. Results All 16 patients were treated surgically, including subacute thyroditis with thyroid cancer in 4 patients, Hashimoto's disease with thyroid cancer in 12. The carcinoma of thyroid were composed of 12 papillary, 3 follicular, and 1 mixed papillary follicular cancer. The 16 patients were followed up for 2 months 9 years, showing they were all alive and healthy. Conclusions In order to avoid delaying the treatment of thyroid cancer, the following thyroiditis with thyroid nodule should be operated earlier: (1) The nodule in thyroditis didn't alter to smaller and shows a tendency to be enlarge after systematic drug therapy. (2) the cold nodule is of cold character in SPECT but solid in ultrasound.

0.05).Conclusion The standard test methods are more effective in detecting G.lamblia than C.parvum.No G.lamblia and C.parvum contamination has been found in drinking water in the Tianjin and Shenyang.

Objective To establish a polymerase chain reaction method for the detection of the rcp virulence gene of L. pneumophila. Methods Sixteen strains of Legionella pneumophila, L. dumiffii, L. bozemanii and L. Longbeachae isolated from the cooling towers of the centralized air-conditioning systems in Tianjin form 2005 to 2007 were detected by polymerase chain reaction method using L. pneumophila rcp virulence gene-specific primer according to GenBank published nucleotide sequence. Results The 900 bp rcp genetic fragment was amplified in three strains of L. pneumophila, while others not. Conclusion The rcp virulence gene-based polymerase chain reaction method for the detection of L. pneumophila has been successfully established and is the foundation for the studies of Legionella virulence.
