BNP (B-type natriuretic peptide) and NT-proBNP (N-terminal pro-B-type natriuretic peptide) are peptide hormones secreted by the heart.Recently, many researches have described that BNP and NT-proBNP were useful markers for the diagnosis of heart failure.We should develop these assays correctly on the basis of full understanding of biological characteristics and guide clinical use for them in medical laboratories.

OBJECTIVE:To observe thc usefulness of Utilin S in treatment of chronic obstructive pulmonary disease(COP- D). METHODS: In a random control design, trial group was given Utilin S 1. 72ug im, qw. on the basis of conventional treat- ment. Control group was given conventional treatment alone. RESLLTS: The clinical effect. symptom and immune indices of trial group were all better then those of control group. CONCLUSION: Utilin S, as a immunostimulant. has a good accessory therapcutic effect on COPD.

Objective To investigate the influence of renal function on serum NT-proBNP in the diagnosis of chronic heart failure by observing the relationship between eGFR and NT-proBNP in serum and comparing cutoff values of NT-proBNP in different eGFR levels.Methods 297 elderly participants were enrolled in the study, including 106 inpatients with heart failure and 191 healthy controls in the corresponding period.The concentration of NT-proBNP was determined by an automated electrochemiluminescence immunoassay on Roche Elecsys 2010.Estimated glomerular filtration rate (eGFR) was calculated using the Levey-modified Modification of Diet in Renal Disease formula. The diagnosis of clinical physician was considered to be the golden standard for heart failure.Results Serum NT-proBNP levels were significantly higher in subjects with renal dysfunction compared with those with normal renal function for heart failure patients [829.1 (202.4 ~ 3725.5) ng/L vs. 227.2 (111.1 ~ 964.2) ng/L, P

74 years were associated with increased cardiac events too(HR = 5.40,95%CI:2.16~11.52,P=0.0002).NYHA classification, LVEF, cTnT?cTnI and CK-MB were not independently predictive of cardiac events.Conclusions Measurement of NT-proBNP in patients with CHF can help to identify patients at higher risk for cardiac events .

Objective This study was designed to investigate positive rate of serum antibody and the distribution of serotypes of Legionella pneumophila in the patients of author's hospital for recent 5 years.Methods All the inspecting results of antibodies in the 1212 serums by indirect immunofluorescence from Jan 1, 2003 to Oct 31, 2007 were reviewed. The clinical information of patients was collected.Results 163 serums were positive (13.5%). Serotype 4 had the highest positive rate of 12.0% followed by serotype 12 (8.5%), 5 (7.8%), 14 (6.1%), 10 (5.9%). Three simultaneously positive serotypes were dominant (21.0%), and 4 or 5 simultaneously positive serotypes were common. In all departments, the highest positive rate (23.3%) was in respiratory ward, in which serotype 4 and 12 were the most (19.0% and 17.2%, respectively).Conclusions Serotype 4 was the most common type of Legionella pneumophila in serotype 1-14. Cross reaction could exist between Legionella pneumophila and other pathogenic microorganism or in different serotypes.

Objective:To investigate the results of surgical treatment for multi-level spinal tuberculosis with focal debridement ,bone grafting and primary internal fixation.Method:27 cases of multi-level spinal tuberculosis treated by operation from January 1999 to January 2007 were reviewed retrospectively.3 vertebral bodies involved in 15 cases,4 vertebral bodies involved in 7 cases,5 vertebral bodies involved at least in 5 cases.Of these,there were 5 cases in thoracic vertebra,7 cases in lumbar vertebra,11 cases in thoracolumbar vertebra,4 cases in lumbosacral vertebra.11 cases showed neurological deficit before surgery,According to the Frankel classification,Frankel B in 1 case,Frankel C in 2,Frankel D in 8.The preoperative average Cobb angle of kyphosis was 35°±7° (range,26°-43°).The focal debridement,bone grafting and primary internal fixation were performed for all patients.Among these protocols, 16 cases underwent one staged posterior spinal internal fixation and anterior focal debridement,bone grafting.11 cases had anterior spinal internal fixation with focal debridement and bone grafting.All patients received anti-TB chemotherapy before and after operation.Anti-TB chemotherapy protocols consisting of combinations of rifampin,isoniazid,ethambutol and streptomycin were administered for 3 months which including 3 weeks before the operation and 3 months after the operation,followed by rifampin,isoniazid and ethambutol for a total of 9 months.The clinical outcomes were evaluated according to the criteria designed by WU Qiqiu et al.Result:The average surgical time was 240 minutes (range,150-300min),with the average intraoperative blood loss of 1000ml (range,600-1400ml),There was no complication such as nerve injury and cerebrospinal fluid leakage.The incision in 1 case presented sinus which had a secondary healing later on,others obtained primary healing.The average postoperative Cobb angle of kyphosis was 15°±5°(range,12°-20°).All cases were followed up for an average of 18 months(range, 14-48 months).The patients with paraplegia recovered to the normal in 8 months.Bony fusion was achieved in all cases with mean fusion period of 7 months(range,5-14 months) with no incidence of hardware failure.At the final follow-up,all patients had evidence of clinical heal and the solid bony fusion.Conclusion:Focal debridement,bone grafting and primary internal fixation is reliable in dealing with multi -level spinal tuberculosis.

Objective Tofollowupandanalyzetheoccurrenceofcerebrovascularischemiceventsin patientswithinternalcarotidarteryocclusion(ICAO).Methods Atotalof144consecutivepatients with ICAO admitted to the Department of Neurology,the Air Force General Hospital from January 2007 to January 2012 were enrolled retrospectively. All patients were confirmed as unilateral ICAO with DSA and they were divided into either a symptomatic group (n=74)or an asymptomatic group (n=70)according to whether they had the symptoms of ischemic cerebrovascular disease or not. Both patients of the 2 groups were followed up for at least 2 years. Their transient ischemic attack (TIA)and endpoint events were observed,including new symptomatic cerebral infarction,death from any cause,as well as patency of collateral circulation,andthefollow-upresultsbetweenthetwogroupswerecompared.Results Twenty-one patients (28. 4%)of the symptomatic group had new attack of cerebral infarction,10 cases (13. 5%)had TIA,and 4 cases (5. 4%)died;9 patients (12.9%)of the asymptomatic group had new attack of cerebral infarction,4 cases (5 . 7%)had TIA,and no patients died. Risk of recurrent stroke in patients of the symptomatic group was higher than that of the asymptomatic group (P=0. 025). Kaplan-Meier curves showed that the incidence of endpoint event of the symptomatic group was higher than that of the asymptomatic group (χ2 =8. 428,P =0. 004). There was significant difference in the patent ratio of the primary collateral circulation between the symptomatic group and the asymptomatic group (64. 9%[48/74] vs. 91. 4%[64/70];P=0. 000);the patent ratio of the primary collateral circulation in patients with new cerebral infarction was significantly lower than that in patients without new cerebral infarction (60. 0%[18/30]vs.82.5%[94/114];P=0.013).Conclusion ThepatientswithsymptomaticICAOaremore likely to have cerebral infarction,and they are likely to die. After ICAO,the primary collateral circulation patent has a significant effect on the prognosis.

Methods Between Apr. 2006 and Jun. 2009,60 patients undergone curative treatment for HCC were enrolled in the retrospective analysis. Patients were assigned into four groups (15 each):patients in groupⅠ(serum HBV-DNA≥1.0?105copies/ml) and groupⅡ(serum HBV-DNA

The understanding of anatomical structures and their adjacent relationship is the founda-tion and key to the development of surgical skills and clinical thinking. In clinical teaching for residents and graduate students , we took the advantage of donor operations in organ transplantation and showed abdominal anal operations anatomical features and relationships through different view angles and compre-hensive ways. This new teaching approach was designed in accordance with processes of organ donation, procurement and back-table operation. The main contents included anatomy of abdominal wall layers, rela-tionships among abdominal organs, locations and courses of important structure, as well as medical human-istic education. In the context of organ donation becoming more and more popular and standardized after the cardiac death of Chinese citizens, this teaching approach is worth exploring.

Objectives To investigate HPV infection and its correlati on with the expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibito r of metalloproteinase-1 (TIMP-1) in vulvar squamous cell carcinoma (VSCC). Meth ods HPV6/11 and 16/18 DNA were detected using in situ hybridization in 26 case s of VSCC, 21 cases of vulvar intraepithelial neoplasia (VIN) and 10 specimens o f normal skin. The expression of MMP-9 and TIMP-1 was measured by immunohistoche mical method in these three groups. Results The infection rates of HPV6/11 and 16/18 in VSCC and VIN were 69.23% (18/26) and 38.46% (10/26), 42.86% (9/21) and 28.57% (6/21) respectively, and no HPV6/11 or 16/18 DNA was discovered in norma l skin epidermis. The expression rates of MMP-9 and TIMP-1 in VSCC, VIN and norm al skin epidermis were 92.31%(24/26) and 76.92% (20/26), 90.45% (19/21) and 80.9 5% (17/21), and 80.00% (8/10) and 50.00% (5/10) respectively. MMP-9 expression in HPV positive lesions was higher than that in HPV negative lesions, but no sig nificant difference of TIMP-1 expression was observed in HPV positive and negati ve lesions. Conclusions HPV infection may play a role in the development of VS CC. The higher expression of MMP-9 comparing with that of TIMP-1 may be an early marker of tumor progression in VSCC, and HPV infection may facilitate the invas ion and metastasis of VSCC.
