With the development of computer techniques and medical imaging examining methods , precise radiotherapy is becoming the major direction of radiotherapy for tuomors. Both of tumor control probability and normal tissue complication probability are improved with precise radiotherapy. This paper critically review the value of PET-CT and breathing control in precise radiotherapy for non-small-cell lung cancer (NSCLC).

Objective: To study the dosage application of herbs in class formulas of KaixinSan recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy (Taiping Huimin Hejiju Fang), Essential Recipes for Emergent Use Worth A Thousand Gold (Beiji Qianjin Yao Fang) and Records of Approved Cases of Ancient and Recent Times (Gujin Luyan) and their actions on depression. Method: According to the dosage proportion of different herbs in the three formulas in the three books, two methods were adopted in terms of decocting different herbs separately and mixing them thereafter(group of decocting separately) as well as extracting after decocted all the herbs together (group of decocting together). Classical anti-depression mice models--forced swimming and tail suspending experiments were observed. The data of immovability time of mice were analyzed by statistics. Result: All the class formulas of KaixinSan which have the same medication but different proportion in the three medical books can reduce the immovability time of mice in forced swimming and tail suspending experiments. But the action of KaixinSan recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy was prominent, and the action of the group of decocting together was superior to that of separated decocting. There was significant difference between the group of decocting together in low dosage and the controlled one (P

OBJECTIVE: To investigate the kinetic and thermodynamic characteristics of adsorption of avilamycin on silica gel. METHODS: By measuring the adsorption of avilamycin on silica gel at different temperatures, the adsorption kinetics curves and adsorption isotherm were drawn, and the kinetics and thermodynamic parameters were studied. RESULTS: The adsorption of avilamycin on silica gel could be described well by Pseudo-second-order model. The adsorption process had feature of shrinking nonreactive core model, and the internal diffusion was the main rate-limiting step. The equilibrium adsorption data of avilamycin on silica gel fit the Langmuir isotherms well. The thermodynamic parameters were as follows:change in entropy (ΔS) was 108.115 2 J·mol-1·K-1, change in enthalpy (ΔH) was 24.654 6 J·mol-1, and changes in free energy (ΔG) were -8.752 9, -8.104 3, and -7.455 6 J·mol-1 at 309, 303 and 297 K, respectively. CONCLUSION: The RESULTS: of this study provide a theoretical basis for further study on the isolation and purification of high purity avilamycin by silica gel.

OBJECTIVE: To optimize the formulation of avilamycin self-microemulsifying drug delivery system (SMEDDS) using central composite design-response surface method and evaluate its quality. METHODS: The compositions of avilamycin SMEDDS were screened by solubility experiment and self-emulsifying grading test. The formulation was optimized using Design Expert Software, taking particle size and Zeta potential as dependent variables and the usage amounts of oil, surfactant and cosurfactant as independent variables. RESULTS: The optimized formulation was quickly and conveniently obtained as follows: 36.67% propylene glycollaurate, 42.83% cremophor RH40 and 20.50% diethylene glycol monoethyl ether.The average diameter of the preparation was (28.34±0.06)nm, the Zeta potential was (-1.98±0.24)mV and PDI was (0.15±0.005). CONCLUSION: The central composite design and response surface method is useful for the formula optimization of avilamycin self-microemulsifying drug delivery system.The prediction accuracy of the established mode1 is good.

ObjectiveTo explore the effects of extended nursing intervention (ENI) in nursing ability of discharged patients with intubation of T-tubes.Methods Eighty-two patients with biliary diseases discharged with intubation of T-tubes were equally divided into two groups.The patients in the experiment group were treated with ENI and those in the control group were treated with conventional nursing.Each group received routine nursing and health education before discharge.All patients were followed up by a self-designed written questionnaire.Data regarding patients’ compliance behavior,knowledge of the diseases and satisfaction were collected and analyzed.Result Significant differences were observed between the two groups,the patients in the experiment group exhibiting better compliance behavior,their knowledge of their diseases improved and the rate of satisfaction higher (P<0.05). Conclusion ENI may be effective for the discharged patients with intubation of T-tubes to improve their compliance behavior, enhance their knowledge of their diseases and raise the rate of satisfaction.

ObjectiveTo study the mechanism of differentiation of mesenchymal stem cells(MSCs) into neuron-like cells in vitro.MethodsMSCs of Wistar rats were separated and cultured, and then induced with DMSO and BHA in vitro. The specific marking proteins of neurons, glia and neural stem cells were detected before preinduction, at 24h after preinduction, at 6h, 24h, and 48h after neuronal induction.ResultsAfter the inducement, many MSCs turned into bipolar,multipolar and taper,and then intersected as network structure. Nestin was strong positive at 6h after neuronal induction, and decreased at 24h, 48h after the induction. NeuN was present at 6 h after neuronal induction, and increased at 24h, 48h after the induction.ConclusionMSCs can be induced into neural stem cells(NSCs) at first, and then differentiate into neuron-like cells in vitro.

AIM: To investigate the effects of propofol on the expression of tissue-type plasminogen activator (tPA) and matrix metalloproteinase 9 (MMP9) in the hippocampus and the cognitive function in neonatal rats.METHODS: The 7-day-old rats were randomly divided into 3 groups: the rats in control (CON) group were intraperitoneally injected with normal saline for 7 d;the rats in single dose of propofol anesthesia (SP) group were intraperitoneally injected with normal saline for 6 d and with propofol on the 7th day;the rats in repeated dose of propofol anesthesia (RP) group were intraperitoneally injected with propofol for 7 d.Blood glucose and blood gas analysis were tested in 6 rats of each group.The rats were randomly selected from each group to isolate the hippocampal tissues at 2 h, 24 h, 48 h, 72 h and 30 d after the last injection.The spatial learning and memory functions of the other rats aged 25 d were determined by Morris water maze.The morphological changes of the hippocampus were observed by HE staining and Nissl's staining.The expression of tPA and MMP9 at mRNA and protein levels was determined by RT-PCR and Western blot.RESULTS: Compared with group CON, the protein expression of tPA and MMP9 in RP group was significantly decreased at each time point, while no significant decrease was observed in SP group except at the time point of 24 h.Compared with CON group, the mRNA expression of tPA and MMP9 was down-regulated obviously in RP group, which was not significantly down-regulated in SP group.From the 3rd training day of Morris water maze beginning, the escape latency was prolonged, and the space exploration time and the number of crossing the original platform location were reduced in RP group compared with CON group and SP group, while no significant difference was observed between CON group and SP group.Compared with CON group, the number of nerve cells reduced and nerve cells arranged in disorder in the hippocampus in RP group.Moreover, the number of Nissl body decreased significantly and finally developed into neuronal degeneration and necrosis in RP group, and no significant difference between SP group and CON group was observed.CONCLUSION: Repeated dose of propofol anesthesia leads to long-term cognitive dysfunction in neonatal rats, which may be related to the down-regulation of tPA and MMP9 expression and destruction of normal morphology and function of neurons in hippocampus, whereas single dose of propofol anesthesia has no such effects.
