Objective To assess the value of color Doppler sonographic appearance and ultrasound-guided needle biopsy on confirmation of diagnosis of atypical breast cancer. Methods 12 patients suspected to be suffering from breast cancer were examined with color Doppler sonography and ultrasound-guided needle biopsy, the results were then analyzed and evaluated. Results Atypical breast cancer had small tumors (diameter less than 1.5cm), rounded or lobular in shape, and regular margin without obvious spicule. The tumors presented hypoecho and there was no acoustic attenuation behind the tumors. The intensity of vascular signals could not be taken as significant evidence for positive diagnosis. Results of ultrasound-guided needle biopsy was helpful for confirmation of the diagnosis. Conclusions Color Doppler sonography was important for the examination of tumor of atypical of breast cancer. The cancer could be confirmed in good time by the extended sonography and ultrasound-guided needle biopsy.

Background and purpose: High-dose chemotherapy followed by autologous stem cell transplantation (auto-HSCT) is considered as the ifrst line treatment for patients with relapse/refractory lymphoma after conventional chemotherapy. However, most of these patients still relapse the second time. The purpose of this study was to analyze the efifcacy of the consolidation chemotherapy after autologous stem cell transplantation (HSCT) refractory/relapse lymphoma in high risk. Methods:A total of 38 patients with relapsed/refractory lymphoma including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were included, who were underwent auto-HSCT in our transplan-tation department from Jan. 2010 to Dec. 2013. In treatment group, 19 patients received 2 courses of consolidation che-motherapy after auto-HSCT every 2 to 3 months, with the regimen of mini-BEAM or modiifed mini-CBV. Another 19 patients had no chemotherapy after auto-HSCT as control group. Results:The median follow-up duration was 17.2 and 7.5 months in the treatment and control group respectively. The follow-up data demonstrated prolonged progression-free survival (PFS) in the treatment group than the control group [24.7 months vs 7.8 months, P=0.029 under intend-to-treat analysis ITT;24.7 months vs 5.2 months, P=0.01 under per protocol analysis(pp)]. There is also a trend of improved overall survival (OS) in the treatment group (P=0.055, ITT). Conclusion:Consolidation chemotherapy after auto-HSCT for refractory/relapsed lymphoma patients delay the relapse and tend to improve the overall relapse rate.

Objective To investigate the value of spiral CT in therapy observation during and after radiofrequency ablation (RFA) for lung or liver tumors. Methods Spiral CT-guided RFA were performed in 35 patients (38 lesions) with lung or liver tumors. CT value of lesions during operation and the changes of lesions after operation were observed. Results Thirty-eight lesions were accurately located under spiral CT. The position of the electrode and the expension of claw-like thin needle electrode could be observed directly. CT value of lesions decreased and some gasification foci in some lesions were observed after RAF therapy. One month after RFA, tumor volume decreased, and the tumors present as slightly low-density mass on contrast-enhanced CT. The total effective rate of RFA was 85.71% (30/35). Conclusion Spiral CT is able to accurately guide RFA treatment for lung or liver tumors and evaluate the efficacy of therapy.

Fasting plasma preptin level was assayed by RIA in the patients with different glucose tolerances. Regarding fasting plasma preptin levels, it was higher in females than in males. Fasting plasma preptin level was increased in patients with type 2 diabetes as compared with subjects of impaired glucose tolerance and normal controls, and there were positive correlations with diastolic blood pressure, blood triglyceride, total cholesterol, high-density lipoprotein-cholesterol, free fatty acids, 2 h plasma glucose after glucose load, HbA1C and HOMA-IR, suggesting a potential link between preptin and glucose-lipid metabolism and insulin resistance.

Objective To determine the causes and risk factors of antimicrobial treatment failure in patients with community-acquired pneumonia(CAP). Methods Hospitalized adults with CAP from January 2006 to December 2006 were analyzed retrospectively. Treatment failure was defined as appearance of nonresponding pneumonia and progressive pneumonia. Patient's clinical features were analyzed. Results All of 378 patients were involved in this study. Total antimicrobial treatment failure was happened in 50 patients(32 patients with non-responding pneumonia and 18 patients with progressive pneumonia). The causes were infectious (35 patients,70% ), non-infectious (11 patients,22% ) and undetermined (4 patients,8% ).Mortality of antimicrobial treatment failure was 18%(9/50, 8 patients died of infectious cause, 1 patient had no clear cause of death). Stepwise Logistic regression analysis showed that C-reactive protein, multilobar pneumonia,albumin < 30 g/L,renal function lesion,liver function lesion were related with antimicrobial treatment failure. Independent factors of treatment failure were multilobar pneumonia (P= 0.002) ,albumin <30 g/L(P = 0.001 ) and renal function lesion (P = 0.000). Conclusion The major challenge associated with antimicrobial treatment failure in hospitalized patients with CAP is infection, most of which is infection of drug resistant strain.

AIM: To investigate the effects of lipid-induced insulin resistance on plasma resistin and ghrelin levels in awake rats. METHODS: A hyperinsulinaemic-euglycaemic clamp was established in awake chronically catheterized rats. Two groups of rats were studied either with a 4 h intraarterial infusion of lipid/heparin or saline. Insulin-mediated peripheral and hepatic glucose metabolism was assessed by insulin clamp combined with [~3H]-glucose infusion, and plasma resistin and ghrelin concentrations were examined before and after clamp with ELISA. RESULTS: During clamp, there was a significant increase in plasma free fatty acid (FFA, P

Objective:To observe the expression of cell adhesion molecule CD44 in lung tissue of rats with asthma.Methods:32 SD rats were randomly divided into 4 groups:the normal group and the model group,8 rats in each group.The asthmatic model was established by repeated inhalation of ovalbulium.The expression of CD44 in lung tissue of rats was detected by semi-quantitatively reverse transcription-polymerase chain reaction(RT-PCR) and by means of immuno-histochemical staining.Differential leukocytes counts(neutrophils,eosinophils,and lymphocytes) in bronchoalveolar lavage fluid(BALF) were performed after staining with wright staining.Results:The expressions of CD44 increased one week after OVA challenge(P

AIM: To explore the effect of lysophosphatidylcholine(LPC) on cholesterol efflux from macrophage foam cells, and to offer experimental evidence for research on prevention and treatment of atherosclerosis.METHODS: Peritoneal macrophages and LDL were seperated from mice and serum of healthy volunteers, respectively. The foam cells were derived from macrophages in the presence of Acylated LDL (AcLDL). Cholesterol efflux from cells and LDH activity were measured by enzymetic fluorometry and LDH kit, respectively.RESULTS: After incubated with LPC for 24 hours, cholesterol efflux from macrophage foam cells increased significantly compared to control, and cellular cholesterol was lower than that in control group. At the same time, medium LDH activity of LPC group was not increased obviously. CONCLUSION: Within the dosage of 10-80 ?mol/L, LPC can promote cholesterol efflux from macrophage foam cells in a dose-dependent manner, and this effect has nothing to do with cytotoxity of LPC.

OBJECTIVE:To compare anesthesia effects of 3 anesthesia methods,to investigate anesthesia improvement method for bronch fiber oscope. METHODS:315 patients undergoing bronch fiber oscope were randomly divided into group A(106 cas-es),group B(104 cases)and group C(105 cases). Group A was treated with traditional bronch fiber oscope lidocaine atomization local anesthesia,group B was treated with modified bronch fiber oscope pethidine combined with lidocaine atomization local anes-thesia and group C was treated with three-limb tube connected with laryngeal mask and target-controlled propofol and remifentanil general anesthesia. SaO2,SBP,DBP,heart rate,breathing rate,excellent anesthesia rate,compliance rate,the rate of bodymove-ment and choking,pain recalling rate were compared among 3 groups before and during examination,and ADR was observed. RE-SULTS:Compared with before examination,SaO2 of group A was decreased significantly during examination,with statistical sig-nificance(P<0.05);that of group B and C had no obvious change before and during examination. Blood pressure,heart rate and breathing rate of 3 groups had no obvious change before and during examination. The excellent anesthesia rate and compliance rate of group A were significantly lower than those of group B and C,but the rate of bodymovement cough and pain recalling rate were significantly higher than group B and C,with statistical significantly(P<0.05). The excellent anesthesia rate and compliance rate of group B were significantly lower than those of group C,but the rate of bodymovement cough and pain recalling rate were signifi-cantly higher than group C,with statistical significance (P<0.05). No ADR was found in 3 groups. CONCLUSIONS:Modified bronchoscope atomization local anesthesia and modified painless bronchoscope are better than traditional bronch fiber oscope atomi-zation local anesthesia in anesthesia effect,safety,degree of comfort and acceptability. Modified bronchoscope atomization local an-esthesia was best but most expensive,so these methods can be chosen according to patient’s condition.

Objective To investigate the relationship between the resistance of the Klebsiella pneumoni-ae and the Klebsiella pneumoniae plasmid pNDM-LJ carrying blaNDM-1 by high-throughput DNA sequencing. Methods High-throughput DNA sequencing was carried out by the Illumina Miseq platform , and sequencing data were assembled by Edena software. Contigs were annotated by the RAST server and analyzed by the BLAST server. Results The plasmid pNDM-LJ was 54-kb in size with a GC content of 49%. The plasmid encoded 52 putative functional genes and belonged to the IncX3 group in incompatible classifications. Analysis of the plasmid sequence revealed high similarity with other IncX3 plasmids. The blaNDM-1 gene was located in a complicated gene environment possibly constructed by several transposition events. The 5′ and 3′ ends of the blaNDM-1 gene were adjacent to the ISAba125 and IS 26 respectively , forming a 10.8-kb transposon-like structure. Conclusion The plasmid pNDM-LJ carried the blaNDM-1 gene being resistant to carbapenems and played a possibly impor-tant role in transmission of blaNDM-1 in China.
