Objective To analyze the characteristic of serum proteins in non-small cell lung cancer (NSCLC) patients, establish serum markers pattern for the diagnosis of NSCLC. Methods Surface enhanced laser desorption ionization time of flight mass spectormetry ( SELDI-TOF-MS) technology was used to analyze serum samples. Bio-marker Pattern Software (BPS) was used to detect the protein peaks. Results Sixteen significantly different pro-tein peaks were found in serum samples in NSCLC patients and healthy controls. Eight up-regulated protein peaks and eight down-regulated protein peaks ( P < 0. 001 ) were identified in serum samples of NSCLC patients. Three up-regulated protein peaks(P <0. 05) were identified in serum samples of patients of NSCLC with smoking history. Two up-regulated protein peaks(P <0. 01) were identified in serum samples of patients of squamous carcinoma comparing with adenocarcinoma. No significantly different protein peak was found in serum samples of NSCLC patients at different clinical stages . Conclusion SELDI - TOF - MS technology can identify different protein peaks and so function as a diagnostic tool with high sensitivity and specificity.

Objective To explore the protective effects of geranylgeranylacetone (GGA) on acute renal failure tats induced by isehemia reperfusion (IR) and the possible mechanism. Methods GGA (400 mg/kg) was administered to induce overexpression of heat shock protein 72 (HSP72) in the kidney of Sprague-Dawley (SD) rats. IR model was generated by temporary clamping the left renal artery for 45 minutes followed by right nephrectomy and 24 h reperfusion. A sham-operated group was used as normal control. 24 h after reperfnsion, rats were sacrificed. Blood was collected for measurement of serum creatinine (Scr) and blood urea nitrogen ( BUN ). Paraffin-embedded sections of the kidney were stained with PAS. Histological changes due to tubular damage were quantitated as tubular damage score. TUNEL assay was used to detect the apoptosis, and Western-blot was used to detect the expression of XIAP. Results After renal IR, the increased level of BUN and Scr, the tubular injury and the apoptosis of renal tubular epithelial cells were observed (P＜0.01). At the same time, the decreased level of XIAP was observed (P＜ 0.01). Compared with the control groups, the level of HSP72 expression was up-regulated in oral administration of GGA group (P＜0.05). The expression levels of BUN and serum creatinine were significantly decreased after IR injury in pre-conditioned rats with over-expression of HSP72 (P＜ 0.01 ). Kidney morphology was better preserved in GGA group. Rats with over-expression of HSP72 also revealed reduction of apoptotic cells by TUNEL stain and XIAP degradation by Western blot (P＜0.05). Conclusion GGA attenuates renal IR injury at least in part through inhibiting tubular cell apoptosis by decreasing XAIP degradation and restoring XIAP protein level.

Objective To investigate ultrasonographic (US) features of mucinous breast carcinoma with pathological correlation and to improve the early diagnosis for the mucinous breast carcinoma.Methods Twenty-two patients with 23 focuses mucinous carcinoma of the breast confirmed by pathology were included in this study,retrospectively evaluate sonographic features according to the American College of Radiology(ACR) Breast Imaging Reporting and Data System(BI-RADS) Lexicon,all cases were classified by BI-RADS before operation.Histological type of mucinous breast carcinoma included mixed and pure two forms,the latter was classified into cellular variants and hypocellular variants.The correlation between the ultrasonographic findings of mucinous carcinoma and histologic features in different types were analysed.Results On US examination,all 22 cases presented as solid mass.In pure form,they showed well-defined margins with no pseudocapsule and isoechogenic or hypoechoic internal echo pattern relative to that of subcutaneous fat in 86.7％ (13/15) focuses which histological type were pure type.93.3％ (14/15) of pure type focuses had posterior enhancement.All pure type focuses demonstrated that the orientation of the mass is parallel to the skin line.75.0％ (6/8) of mixed type focuses and 13.3％ (2/15) of pure type focuses,however,demonstrated ill-defined and or spiculated margins with more hypoechogenic structure (P ＜0.01).Mixed type focuses have more aggressive malignant features.65.2％ (15/23) of cases being classified as BI-RADS 4 or 5 were suspected as malignancy,which included 6 mixed type focuses and 9 pure type respectively accounting for 75.0％ (6/8) and 60.0％ (6/15) of each type focuses.Conclusions Mucinous breast carcinoma especial pure type did not have the typical malignant breast masses sonographic features,which showed some benign masses sonographic features except no pseudocapsule benign feature.Mixed type mucinous carcinomas tumors have more aggressive margin imaging characteristics.It is suggested that mucinous breast carcinoma should be classified category 4 by BI-RADS to avoid diagnosis delay.

Objective Acute kidney injury (AKI) is a common complication after cardiac surgery,especially in elderly patients,and related with poor prognosis.Although much advances in therapies of AKI have been obtained,the prognosis of patients did not improved.In the absence of proven interventions,a reasonable strategy would be to identify modifiable risk factors for AKI.The objective of the present study was to explore modifiable risk factors of acute kidney injury after cardiac surgery with cardiopulmonary bypass in elderly patients.Methods Data from 457 consecutive elderly patients (age ≥60 years old)who underwent cardiac surgery with cardiopulmonary bypass in the Guangdong General Hospital between January 2007 and December 31,2009 were analyzed in this retrospective research.The primary outcome was AKI according to the serum creatinine criteria of the RIFLE (renal Risk,Injury,Failure,Loss of renal function and End-stage renal disease) classification as an increase in serum creatinine ＞ 50％ from baseline to peak value within the first seven postoperative days.The baseline serum creatinine was defined as the latest serum creatinine before cardiac surgery.Univariate anadysis was carried out for patients'demographics data and multivariate analysis by logistic regression was used to obtain the independent risk factors for AKI.Results Among 457 elderly patients,patients mean age was (65.22 ± 4.17) years and they comprised 253 (55.4％) men and 204 (44.6％) women.AKI occurred in 313 (68.5 ％) participants.Compared with patients without postoperative AKI,the media length of intensive care unit was longer in patients with postoperative AKI,4.0 (2.0-7.5) days versus 2.0 (1.0-3.0) days,respectively.In logistic regression model,malc (odds ratio[OR] 1.894,95％ confidence interval[CI] 1.136-3.157),age above 65 years (OR 2.391,95％ CI 1.381-4.142),hypertension (OR 2.286,95％ CI 1.249-4.184),estimated glomerular filtration rate less than 60 ml/min (OR 1.933,95％ CI 1.111-3.362),preoperative uric acid ＞ 450 μ mol/L (OR 2.938,95％ CI 1.633-5.285),use of angiotensin converting enzyme inhibitors/angiotensin receptor inhibitors (ACE1/ARB) before cardiac surgery (OR 2.196,95％ CI 1.283-3.759),use of ACEL/ARB after surgery (OR 0.329,95％ CI 0.156-0.691),use of diuretics (OR 0.149,95％ CI 0.068-0.326),time of cardiopulmonary bypass above 120 min (OR 5.228,95％ CI 3.023-9.041) and prolonged mechanical ventilation (OR 2.921,95％ CI 1.527-5.586) were independent factors of AKI after cardiac surgery with cardiopulmonary bypass.Conclusion Preoperative uric acid above 450μmol/L was a modifiable risk factor of AKI after cardiac surgery with cardiopulmonary bypass in elderly patients.Therapies aimed at mitigating high preoperative uric acid may offer protection against this complication.

OBJECTIVE: To investigate the association between transporter associated with antigen processing 1 (TAP1) rs1057141 and rs1135216 gene polymorphisms and predisposition to allergic rhinitis (AR) in Xinjiang Han people. METHOD: A case control study was conducted. The region of the TAP1 * rs1057141 and rs1135216 was studied in 150 Xinjiang Han people with allergic rhinitis and 150 normal controls by using SNaPshot system, and these data were compared with other ethics groups in the world according to the NCBI gene bank. RESULT: The genotypes distribution of the group were in the Hardy-Weinberg equilibrium(P>0.05). The frequencies of three genotypes(G/G, G/A, A/A) of TAP1 * rs1057141 were 4.00%, 30.00%, 66.00% in controls and 2.70%, 33.30%, 64.00% in AR groups , which showed no difference (P>0.05). The frequencies of three genotypes (G/G,G/A,A/A) of TAP1 * rs1135216 were 2.0%, 28.7%, 69.3% in controls and 1.30%, 27.30%, 71.40% in AR groups, which showed no difference either (P>0.05). According to the NCBI database, there was difference between Xinjiang Han people and other ethnics in the world. CONCLUSION Lacking association was found between the mutation of TAP1 * rs1057141, rs1135216 gene G allele and allergic rhinitis in the Xinjiang Han people. Maybe TAP1 * rs1057141, rs1135216 were not susceptibility genes to AR. And apparent differences existed in TAP1 gene polymorphisms between Xinjiang Han people and other ethnic groups in the world.
