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.

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.

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.

Under the guidance of meridian theory, the acupoints heat-sensitive moxibustion is a treatment method which applies moxa stick to perform mild moxibustion at heat-sensitive acupoints, which can arouse the meridian sensation transmission and promote the movement of meridian qi; consequently, the qi can be extended to the diseases. For its many advantages, such as no direct contact on skin, no injuries, no pains, fewer side effects, easy operating and moderate cost, the acupoints heat-sensitive moxibustion is widely accepted in dermatology, male urology disease, rectum and anus diseases and breast diseases. The application and research status of the acupoints heat-sensitive moxibustion in traditional Chinese surgery in recent years is reviewed, and several problems and suggestions in its clinical application and research are proposed, aiming to provide clinical basis for its further development and clinical application in traditional Chinese surgery.
