Objective To evaluate the clinical application of transendoscopic Doppler ultrasonogra-phy in various gastrointestinal diseases. Methods Transendoscopic Doppler ultrasonography was performed in 59 patients with various gastrointestinal diseases. Results The Doppler signals were detected beneath the peptic ulcer base in 29 of 39 patients (74. 4% ) . For acute ulcer bleeding and non - bleeding, the Doppler - positive rates were 87. 5% and 65. 2% , respectively, and the measured depth of vessels were 0. 49 mm and 0. 65mm (P

[Objective]To explore the correlation between anticardiolipin antibodies and post-SARS patients with osteonecrosis,investigate the etiology of post-SARS osteonecrosis,and select the sensitive molecular symbols for early diagnosis and distinguish the high risk population.[Method]The studied subjects were divided into two groups.Sixty-two post-SARS patients with osteonecrosis was one group,and 52 matched healthy people was as normal controlled group.Empty stomach blood samples from cubital veins were collected from both groups.IgA,IgG and IgM of anticardiolipin antibodies types were examined by ELISA.[Result]Twenty-one of 62 post-SARS osteonecrosis patients were tested at least one type of anticardiolipin antibodies positive,among them,with IgA(11.33?11.209)APL,IgG(5.127?5.927)GPL,IGM(17.821?10.606)MPL.Four of 52 control group persons were detected positive,with IGA(10.702?3.126)APL,IgG(5.184?4.780)GPL,IgM(14.684?5.516)MPL.There were significant differences between two groups,while,there were no difference in prothrombin time(PT),thrombin time(TT),prothrombin activity(PTA)and international normalized ratio(INR).[Conclusion]The study indicates an increased positive incidence of anticardiolipin antibodies in post-SARS patients with osteonecrosis.This has reflected that anticardiolipin antibodies may play a role in osteonecrosis.

Objective To summarize the clinical results of combined procedure of resections and constructions of bronchus,great vessels and heart in the treatment of 79 patients with central lung cancer.Methods From Jun,1988 to Jun,2005,the combined procedure of resections and constructions of bronchus,great vessels and heart were carried out in 74 patients with central lung cancer.The operations included ring of bronchus or sleeve lobectomy in 57 cases,double sleeve lobectomy in 15 cases,carinal resection and reconstruction in 4 cases.Results There was no operative deaths and 7(8.86 %) patients had operative complications.The survival rates of 12,36,60 months and 10 years were 78.5%,59.5%,35.4% and 17.7% respectively.Conclusion With the treatment of sleeve lobectomy or combined with resection and reconstruction of pulmonary artery,great vessels or heart,the pulmonary function can be protected significantly,and the cure rate and the long term survival rate can be improved in patients with central lung cancer.

BACKGROUND:Interstitial fluid flow around the osteocytes caused by a series of physiological activities plays an important role in the osteocyte metabolism and signal transduction.
OBJECTIVE:To review and summarize the research progress of bone structures and physiological functions, then further il ustrate how the mechanical loads make an impact on bone tissue.
METHODS:A computer-based search was conducted in PubMed database for articles related to the bone microstructure, metabolism and osteocyte signal transduction published from January 2009 to December 2015. The keywords were“osteocyte, mechanical load, permeability, lacunar-canalicular system, interstitial fluid flow, mechanotransduction, signaling pathways”in English. Data were screened firstly, dated articles or literatures with wrong research methods were excluded, and total y 40 eligible articles were enrol ed.
RESULTS AND CONCLUSION:Bone tissue can quickly adapt to the change of mechanical environment to guarantee enough osteocytes in the functional bone area indicating that osteocytes regulate the bone absorption and formation by responding to stress, which is closely related to osteocyte physiological characters. Osteocytes exist in mineralized matrix, and the special microstructures make it possible to receive mechanical loads and transform the mechanical signals into chemical signals aimed at regulating the bone absorption or formation.So the interstitial fluid flow in the lacuna-canalicular system occures, namely load-induced fluid flow, when the mechanical load is distributed on the bone. This fluid flow affects the bone tissue through two mechanisms:regulating osteocyte metabolism and participating in the mechanotransduction. In conclusion, the mechanical load plays a vital role in maintaining health bone and regulating bone adaptation.

[Summary] The article reported 107 cases of bile duct residual stones treated by plasma shock wave lithotripsy with inverse flush under fiber choledochoscope via T-tube fistula.Of the 107 patients, stones were completely removed in 98 patients, and residual stones remained in 9.Intraoperative biliary hemorrhage occurred in 5 cases, which were stopped after spraying the norepinephrine . There were 4 cases of arhythmia , 13 cases of subcostal or upper abdominal pain , and 11 cases of abdominal distention and diarrhea , all of which were cured by symptomatic treatment .Postoperative biliary infection occurred in 7 cases, which were cured by anti-infection and biliary drainage.Except for 1 patient of lost of follow-up, 106 patients were followed for 6 months.Ultrasound and CT examinations showed free of calculus in 101 cases, and intrahepatic bile duct residual stones in 5 cases.We deem that plasma shock wave lithotripsy combined with reverse flushing under fiber choledochoscope is a minimally invasive , safe, and effective treatment for difficult biliary residual stones .

Using chemotherapy (DA or HA and ATRA) to treat 22 cases of acute promyelocytic leukemia following to give PSS (100mg/d X 7d) ,the patients complicated with DIC were treated then were given the chemotherapy,combined with PSS to end. The results showed that the complete remission rate of the therapy of APL with PSS was increased to

OBJECTIVE To study the prevalence,fungal species,therapy and prevention of invasive fungal infections in our Affiliated Hospital.METHODS From Jan 2004 to Dec 2005,all patients with positive results for fungal culture of blood and sterile fluid were reviewed retrospectively.The in vitro activity of antifungal agents against fungal isolates was determined.RESULTS Eighty-eight positive patients were collected in this analysis based on the diagnosis of invasive fungal infection in our hospital for two years,from them the majority were diagnosed as candidal infections(n=72,81.8%),the others were Cryptococcus neoformans(n=8,9.1%),Aspergillus(n=5,5.7%) and other different fungal infections.The most common was C.albicans(n=48,66.7%),C.glabrata(n=12,16.7%),and C.tropicalis(n=8,11.1%),C.parapsilosis and C.krusei were both the same results(n=2,2.8%).CONCLUSIONS Infections caused by Candida are the most common invasive fungal ones in our hospital,and C.albicans is the most common one.Fluconazole remains effective for treament of candidal infections,especially those caused by C.albicans.

When we did compatibility testing, we found a case of leukemia with irregular antibody. The antibody specificity was identified as anti-Ce using panel-cell, and was IgG antibody. The anti-Ce antibody had both anti-C and anti-e activity. It is very difficult to find a Ce antigen negative blood for transfusion. The compatible donors rate is very low, only 2%-3%.
