Objective To investigate the expressions of AGGF1 in esophageal squamous cell carcinoma (ESCC) and their relationships with clinical features and prognosis of ESCC. Methods The expressions of AGGF1 in 70 cases of ESCC and 30 cases of normal esophageal tissue were examined using SP immunohistochemical staining and were analyzed according to the clinical features and follow-up data. Results The expressions of AGGF1 in 70 cases of ESCC was significantly higher than those in 30 cases of normal esophageal tissue [54.29%(38/70) vs. 23.33%(7/30)](P=0.004). The expressions of AGGF1 in ESCC were significantly related to the TNM stage, clinical stage and prognosis (P all<0.05). The OS was shorter in the positive teams of AGGF1 than that in the negative teams [(19.7 ± 3.5) months vs. (33.2 ± 4.0) months] (P=0.015). Cox- proportional multivariate analysis showed that positive expressions of AGGF1 and VEGF (P=0.043, 0.024) and clinical stage (P=0.035) were significant prognostic factors in overall survival. Conclusions AGGF1 has high expressions in ESCC, and it is closely related to the clinical features and prognosis of ESCC.

Objective To establish a simple and practical superparamagnetic immunochromatographic test strip for rapidly monitoring human serum level of CA72-4. Methods Water-soluble carboxylated super-paramagnetic nanoparticles were prepared with a modified one-step hydrothermal synthesis method. Magnetic probe was prepared by immobilizing specific antibody (mAb1) onto the surface of nanoparticles. Following with optimization and assembly of the test strip , we evaluated sensitivity , specificity , stability of this method for serum CA72-4 detection. Results The optimized test strip provided not only the qualitative results, but also the high sensitivity quantitative detection through stable magnetic signal. The detection limit was 0.83 IU/mL. One hundred clinical samples ( 70 positive and 30 negative ) were measured to assess these test strips with high sensitivity (99%) and high specificity (93%). The test strip and magnetic signal possessed high stability. Conclusion A rapid and quantitative detection of CA72-4 by the test strip was accomplished. This method is rapid, sensitive and quantitative, possessing great potential in large sample screening or in-home testing.

Intensity-modulated radiotherapy (IMRT) is gradually replacing conventional radiation therapy and has become the mainstream radical treatment for patients with nasopharyngeal carcinoma (NPC). IMRT can conform and increase radiation doses to tu-mor-associated regions as well as decrease exposure doses and volumes on normal organs and tissues to avoid damage on critical or-gans. Aside from system and setup errors, other factors, such as the gradual reduction of the primary NPC lesion and the decrease in vol-ume of involved neck lymph nodes as well as body weight loss and changes in the head and neck shape during IMRT, may cause devia-tions in the radiation doses and volume delivered to the NPC targets and the organs at risk. These factors may affect the accuracy of IMRT. Several researchers have attempted to correct such deviations during IMRT for NPC patients by using adaptive radiotherapy (ART). The results indicate that ART is feasible to a certain degree and can correct the deviations, including decrease in tumor volume, body weight loss, and changes in head and neck shape of NPC patients.

Objective To investigate the characteristic immunophenotype of B cell chronic lymphoid leukemia in china. Method Single and multiparameter flow cytometry were used to analysis 163 cases of B cell chronic lymphoid leukemia. Results 71.8%(117/163) of cases co-expressed CD5 and B cell markers. The patients were classified into category of B cell chronic lymphocytic leukemia(B-CLL), hairy cell leukemia(HCL) and other B-cell lymphoproliferative disorders(LPDs) by using the scoring system that was recommended by world health organization (WHO). The B-CLL typically display the composite phenotypes: CD5+,CD23+,CD20+,CD19+,HLA-DR+,but the CD22,CD11c,CD25 and FMC7 were variable present in some B-CLL cases.CD103 seems the most specific marker for HCL.To differentiate diagnosis of atypical B-CLL with B-prolymphocytic leukemia(B-PLL) or mantle cell lymphoma(MCL), one must not rely exclusively on immunophenotypic dates, cytogenetic or molecular biology detection would be helpful. The index of froward scatter( FSC) and antigens expression of tumor B cells could be calculated by dividing the relevant value of residual normal T cell within same sample as internal control, so the cell size and the intensity of antigen expression could be comparable each other and quantitative between different investigations. Conclusion immunophenotypic analysis is an extremely useful adjunct in the diagnosis of chronic lymphoid leukemia.

OBJECTIVE:To analyze intervention effect of Drug Rational Usage Guidelines System(DRUGS)on antibacterial agents use in department of obstetrics and gynecology in our hospital. METHODS:The application of antibacterial agents in depart-ment of obstetrics and gynecology in our hospital during Jan.-May(before intervention)and Jun.-Nov. 2012(after intervention)were extracted in respects of drug name,preoperative medication duration,perioperative additional condition,postoperative drug with-drawal time,drug combination,usage and dosage,average hospitalization stay,hospitalization cost. The intervention effects were analyzed. RESULTS:After intervention,the type of antibacterial agents were more in line with national regulations;the proportion of type Ⅰ incision surgery without antibacterial agents increased from 57.8% to 75.2%;the prophylactic application of antibacteri-al agents in type Ⅱ incision surgery within 0.5-2 h increased from 80.2% to 97.0%. The rate of reasonable antibacterial selection, drug combination,usage and dosage increased from 76.9%,64.9%,71.3% to 89.3%,84.6%,90.2%,respectively. The average hospitalization stay and antibacterial cost per capita decreased significantly. There was statistical significance among above indica-tors before and after intervention(P<0.05 or P<0.01). CONCLUSIONS:DRUGS effectively change irrational use of antibacterial agents in department of obstetrics and gynecology,which provide a new method for the management of antibacterial agents.

Water deprivation and loading tests were performed in a patient with sustained hypernatremia and hypodypsia. Results suggested that the regulation of ADH release was still retained despite of the raised threshold, being consistant with the diagnosis of essential hypernatremia. The hypernatremia of this patient was partially improved by dihydrochlorothiazide and desmopression acetate (DDAVP).
