Objective To explore the efficiency of arterial perfusion chemotherapy combined with embolization for the treatment of giant carcinoma of the kidney. Methods Arterial perfusion chemotherapy combined with embolization was performed through the renal artery in 21 cases of giant carcinoma of the kidney from April 1992 to April 2006. The chemotherapeutic agents contained carboplatin(300 mg), mitomycin(20 mg) and cyclophosphamide(800 mg). The embolization was conducted with anhydrous alcohol, sodium morrhuate, and lipiodol plus gelatin sponge. Results The arterial perfusion with embolization was successfully obtained in all 21 cases. Surgical resection was accomplished in 15 cases, 1 - 8 weeks after the embolization; revealing severely less or no blood supply to the tumor. Pathological findings showed marked necrosis of tumor cells with peripheral inflammatory infiltration, fibrous proliferation as well as capillary embolization. The survival rates at 1-, 2-, and 3-, year were 80%(12/15), 53.33%(8/15) and 40%(6/15) respectively. Conclusions Combination of perfusion chemotherapy and embolization through the renal artery for the treatment of giant carcinoma of the kidney offers promising clinical effects.

Objective To construct the performance evaluation framework for China′s health system,and provide evidences for enhancement of such evaluation and the health system.Methods Literature review and empirical research were combined with expert consultation to construct such an evaluation index system.Results In view of both international experiences and China′s specifics,an evaluation index system is built based on the generalized concept model of the health system,consisting of 4 class-1 indicators, 1 5 class-2 indicators and 6 9 class-3 indicators.Conclusions The generalized framework of health system performance evaluation fits such evaluation in China,and indicator optimization and understanding of the shortcomings with cautious explanation are of critical importance.This evaluation remains in its infancy in China,and there is a long way to go before a health system performance evaluation system can be built in China.

The mammalian cell nucleus is highly structured and organized into various membrane-less nuclear compartments called nuclear bodies. Nuclear bodies are highly dynamic structures, with a variety of substances gathered inside to promote the more efficient conduct of certain biological reactions. It dynamically produces responses under different biological processes and stress conditions such as tumorigenesis, apoptosis, antiviral defense, and plays an important role in regulating cell homeostasis. Tumor is a major public health problem, and finding new targets is the key to tumor therapy. How the nuclear bodies are involved in the development of tumor has not been reported. This review aims to provide a new understanding of how the nuclear bodies regulates tumor progression and provide a new effective strategy for tumor prevention and treatment.

To compare the pharmacokinetics of syringin, eleutheroside E and isofraxidin after intravenous administration of each monomer and Ciwujia injection. Twenty-four Sprague-Dawley rats were randomly divided into four groups and intravenously administrated with syringin, eleutheroside E, isofraxidin, and Ciwujia injection, respectively. The concentrations of the three components in rat plasma were determined by LC-MS/MS. DAS 2.0 software was applied to calculate the pharmacokinetic parameters while the SPSS 17.0 software was used for statistical analysis. Significant difference (P < 0.05) was found between each monomer and the injection on the main pharmacokinetic parameters such as AUC, CL and t1,/2. Compared with the injection, the group treated with the syringin has obvious decrease in AUC, and increase in CL while the group treated with eleutheroside E has obvious increase in AUC, and decrease in CL The t1/2 of isofraxidin was prolonged in Ciwujia injection. Pharmacokinetic characters of the ingredients in the injection varied greatly from the monomer. Other constituents in the injection may have an impact on the pharmacokinetic profiles of these three components.

Neurofeedback, as an alternative treatment method of behavioral medicine, is a technique which translates the electroencephalogram (EEG) signals to styles as sounds or animation to help people understand their own physical status and learn to enhance or suppress certain EEG signals to regulate their own brain functions after several repeated trainings. This paper develops a neurofeedback system on the foundation of brain-computer interface technique. The EEG features are extracted through real-time signal process and then translated to feedback information. Two feedback screens are designed for relaxation training and attention training individually. The veracity and feasibility of the neurofeedback system are validated through system simulation and preliminary experiment.

To establish a method for the determination of cucurbitacin in plasma samples, in order to study the in vivo pharmacokinetic characteristics of cucurbitacin in rats. Rats were intravenously injected with cucurbitacin. With diphenhydramine as the internal standard (IS), the plasma concentrations of cucurbitacin in rat plasma at different time points were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS). With electrospray ionization source, the positive ion detection in the multiple reaction monitoring mode was conducted to determine the ion-pairs for target compound and IS were m/z 503.2/113.1 and m/z 256.0/167.2, respectively. Agilent ZOBAX SB-C18 column (2.1 mm x 50 mm, 1.8 microm) was adopted and eluted with methanol and 0.1% formic acid (55:45), and the flow rate was 0.2 mL x min(-1). DAS 2.0 software was applied to fit the blood concentration and calculate corresponding pharmacokinetic parameters. The rats were intravenously injected with cucurbitacin at the concentration of 3.0 mg x kg(-1). The target blood quality concentration show good linear relations within the range of 10.5-3 150 microg x L(-1) (R2 = 0.996), the lower limit of the standard curve was 10.5 microg x L(-1), and the signal to noise ratio S/N = 12. Intra- and inter-day precisions RSD was less than 6.9% and 14%, respectively; The accuracy RE ranged between 0.20% and 3.7%; The extraction recoveries ranged between 92.7% and 97.1%. Regarding the pharmacokinetic parameters of tail intravenous injection of cucurbitacin, AUC (0-t) was (811.615 +/- 111.578) microg x h x L(-1), (t1/2) was (1.285 +/- 1.390) h, CL was (3.627 +/- 0.487) L x h x kg(-1), and V(d) was (6.721 +/- 7.429) L x kg(-1). In this study, researchers established a simple, accurate, sensitive and highly specific method for determining the blood concentration of cucurbitacin, and reported the in vivo pharmacokinetic characteristics of cucurbitacin in rats for the first time.

Breast cancer is the leading cause of malignancy-related mortality in women worldwide. The more accurate prediction of lymph node metastasis and evaluation of personalized prognosis of breast cancer patients could provide evidence and reference for individualized comprehensive treatment and clinical decision-making. Nomogram is statistical calculation model developed to generate individualized prediction of a certain clinical event through the factors associated with it. Currently breast cancer related nomogram models is most commonly used in the prediction of non-sentinel lymph node status in patients with sentinel lymph node-positive breast cancer, sentinel lymph node metastasis in clinical node-negative breast cancer and prognosis evaluation of breast cancer. This article reviewed the recent advances in breast cancer related nomograms according to the above mentioned three aspects, and evaluated respectively the predictive factors, accuracy, characteristics and clinical application potential.
