Objective To explore the social economic factors related to depressive in patients with long-term hemodialysis.Methods A total of 122 patients with hemodialysis for more than 3 months from December 1st 2008 to February 1st 2009 in Dongfang Hospital and Wangjin Hospital,were divided into a depression group (41 cases) and a non-depressed group (81 cases).Informations such as economic status,social interaction,education,hobbies,etc were collected by questionnaire and the relationship between these factors and depression was analyzed.Results There was significant difference between the two groups in the factors of economic status,social interaction,education,and hobbies (x2 values were 14.671 、6.256、6.744、6.390,P＜0.05).There was no significant difference in the factors of gender,drinking,relationship of family,profession,the condition of housing,social status,seasons of born,and careers,etc (x2 values were 3.651、0.765、2.034、3.093、0.772、5.956、2.687、5.138,P＞0.05).Conclusion Thepatientswithpooreconomic,lower education,less social communication,fewer hobbies,and no smoking habits are easy to be depressive.

Objective To evaluate method of CT simulation (CT sim) in the treatment planning setup of esophageal carcinoma. Methods From Dec.1999 to Jun.2002, 49 patients with pathologically proved esophageal carcinoma were analyzed. All patients underwent CT sim and treatment planning was configured with three symmetrical fields in the isocenter mode. A few comparisons have been made between CT sim and conventional simulation (Con sim) in the treatment planning setup. Results The difference in isocenter position were observed between CT sim and Con sim with 3～18 mm.When the esophageal lumen was taken as portal center, the 90% isodose curve in 42.8%(21/49) of patients were able to cover the whole lesion. When taking the tumor as the portal center, the whole lesion of all patients was totally covered by the 90% isodose curve. Conclusion The CT sim has an advantage in the delineation of lateral extension of esophageal tumor than the Con sim .Selection of irradiation portal should be done according to the size the silhouette of the tumor.

OBJECTIVE: To investigate the reaction mechanisms of magnolol (MG) binding with bovine serum albumin (BSA) and human serum albumin(HSA) by using different equations. METHODS: The characteristic spectra of HSA/BSA-MG interaction system were determined by using spectral experiment. The binding constants, energy transfer parameters and thermodynamic parameters were calculated by logarithmic equation and nonlinear equation, and the influence of MG on molecular conformation of BSA/HSA was also investigated. A comparative analysis of the interaction of MG with HSA/BSA was performed. The different equations were applied to deal with the experimental data and the feasible modeling equation was suggested. RESULTS: Static quenching exited between MG and SA with significant bond strength. The value of binding distances (r) was low, which indicated the occurrence of energy transfer. Fluorescent phase diagram technical analysis showed that the reaction conformational pattern of MG-BSA was "two-state" model; MG-HSA was a sequence change process. According to the obtained thermodynamic parameters, the main interactional forces between MG and SA were judged to be hydrogen bonds and Van der Waals forces. The results of molecular modeling revealed that hydrogen bonds and Van der Waals forces were the main binding forces in the MG-BSA/HSA system, and hydrophobic interaction was also present. These results were in accordance with spectral experiments. CONCLUSION: There are differences between the interaction mechanisms of MG-BSA and MG-HSA. Logarithmic equation is the most suitable equation for this system.

OBJECTIVE: To prepare a novel inclusion complex of the piperine with β-cyclodextrin (β-CD) by the saturated solution method and characterize the inclusion mechanism by fluorescence spectroscopy and ultraviolet spectrometry. METHODS: The dissolution properties and the balance properties of the inclusion complex were analyzed by ultraviolet spectrum and the Gaussian method was used to calculate the inclusion complex's configuration and thermodynamic parameters. The interaction performance of β-cyclodextrin-piperine supermolecular system was explored by spectroscopic experiment combined with theoretical calculation. RESULTS: The results showed that the spectral method better characterize the piperine-β-cyclodextrin. The stability and solubility of piperine was significantly improved after it was included with β-cyclodextrin. Gaussian calculation successfully obtains the preferred molecular configuration and the total energy change effect of inclusion system, the thermodynamic parameters of the piperine-β-cyclodextrin were also be obtained and showed that the inclusion process of the inclusion complex is a spontaneous binding reaction, which was further confirmed by spectral experiments. CONCLUSION: The stability and solubility of piperine can be significantly improved after β-cyclodextrin including, the results can provide certain reference for the study of inclusion complex supermolecular system.

Objective: To explore a more effective treatment regimen for patients with acute promyelocytic leukemia (APL) after complete remission (CR). Methods: Fifty patients with newly diagnosed APL were induced to CR by all-trans retinoic acid (ATRA). They were divided into two groups. Twenty-three patients in group A were given with alternative therapy with compound realgar and natural indigo tablet (CRNIT) and combined chemotherapy. Twenty-seven patients in group B were treated with alternative therapy with ATRA and combined chemotherapy. Long-term clinical outcomes were compared between the two groups. Results: Eight of the total 50 patients relapsed. The relapse rates in group A and group B were 4.3% and 25.9%, respectively. The difference was significant (P = 0.038). The three-year and five-year disease-free survival (DFS) rate of group A was markedly superior than group B (100% and 91% vs 79% and 58%; P = 0.023). Conclusion: Alternative therapy with CRNIT and combined chemotherapy for APL patients after CR was more effective than that of ATRA and combined chemotherapy.

OBJECTIVE: To study the binding mechanism between adenosine (Ade), an active component of some traditional Chinese medicines, and human serum albumin (USA). METHODS: The binding constant K and binding sites n were obtained by using fluorescence and UV absorption spectroscopy. In addition, the reaction mechanism was discussed. The energy transfer parameters of the reaction system were determined as was the effect of Ade on HSA's conformation on the basis of Fōrster theory. The binding reaction model of HSA with Ade was constructed through molecular simulation and compared with the experiment results. RESULTS: Ade could bind HSA to form static complex. The binding constant (K) was 1.39 × 10 L3 · mol-1 and binding sites (n) was 0.94. The binding distance r between Ade and HSA was very short, which indicated the phenomenon of energy transfer. Ade changed the hydrophobic environment of the binding domain in HSA and caused certain changes for micro area conformation. Computer molecular docking technology showed that the interactions of Ade with HSA were mainly hydrophobic interaction and hydrogen bonding between purine ring of Ade and amino acid residues of HSA. CONCLUSION: The theoretical calculation and experiment results were in consistency, which provided certain reference for the study of pharmacological mechanism for the active ingredient of some traditional Chinese medicines, adenosine.
