Surgery is the main treatment for rectal cancer, which is one of influencing factors of the patients’quality of life (QoL). Factors affecting QoL in a operation include tumor location, surgical margin, operation approach, appearance of stoma, application of laparoscopy and so forth. Still, now there are lots of arguments on how operations affecting QoL. The fol-lowing is a review about patients’QoL after different rectal surgeries, including high versus lower anterior resection, anterior versus inter sphincteric resection, transanal versus open operation, anal-sparing versus stoma operation, laparoscope versus open surgery.

OBJECTIVETo study the effects of JTS, Traditional Chinese Medicine caps. treating cerebral ischemia on metabolism and antioxidant system in cerebral ischemia rat.

METHODSI.m. dexamethasone and ligating common carotid artery, the model of cerebral ischemia rats was established to investigate the effects of JTS caps. and its mechanisms through detecting substance metabolism, energy metabolism and antioxidant system.

RESULTSJTS caps. (1.78 - 3.56 g/kg) could upgrade glucose (Glu), total amino acids (T-AA), ATP, Na(+)-K(+) -ATPase, superoxide dismutase (SOD) and catalase (CAT) of brain tissue and degrade lactic acid (LD), malondialdehyde (MDA) and water content of brain tissue in cerebral ischemia rat (P < 0.05, 0.01). JTS caps. (3.56 g/kg) could also depress extenuation of rat's body weight.

CONCLUSIONJTS caps. has some protections against the cerebral ischemia in rats, and one of the mechanisms may be improving the metabolism and antioxidant system.

A double targets of high throughput screening model for xanthine oxidase inhibitors and superoxide anion scavengers was established. In the reaction system of xanthine oxidase, WST-1 works as the probe for the ultra oxygen anion generation, and product uric acid works as xanthine oxidase activity indicator. By using SpectraMax M5 continuous spectrum enzyme sign reflectoscope reflector, the changes of these indicators' concentration were observed and the influence factors of this reaction system to establish the high throughput screening model were studied. And the model is confirmed by positive drugs. In the reaction system, the final volume of reaction system is 50 μL and the concentrations of xanthine oxidase is 4 mU x mL(-1), xanthine 250 μmol x L(-1) and WST-1 100 μmol x L(-1), separately. The Z'-factor of model for xanthine oxidase inhibitors is 0.537 4, S/N is 47.519 9; the Z'-factor of model for superoxide anion scavengers is 0.507 4, S/N is 5.388 9. This model for xanthine oxidase inhibitors and superoxide anion scavengers has more common characteristics of the good stability, the fewer reagent types and quantity, the good repeatability, and so on. And it can be widely applied in high-throughput screening research.

To establish a method for the determination of astilbin, peoniflorin, rasmarinci acid, isofraxidin and liquiritin contained in Shaolin Xiaoyin tablets, in order to lay a foundation for designing late-stage dosage forms and clinical medication schemes. In this paper, efforts were made to establish a method for the determination of the blood concentration of the five components and study the in vivo pharmacokinetics in rats. The blood concentration was determined by HPLC. Phenomenex C18 column (4.6 mm x 250 mm, 5 microm) was adopted and eluted with methanol-acetonitrile-0.05% formic acid, the flow rate was 0.8 mL x min(-1), and the wavelength was 275 nm. The samples were processed by the solid phase extraction method. After oral administration of Shaoling Xiaoyin tablets, the rat bloods were collected at different time points to determine the blood concentrations. The experimental results showed that the baseline separation could be adopted for the five components, and astilbin, peoniflorin, rasmarinci acid, isofraxidin and liquiritin showed good linear relations within ranges of 2.48-248, 0.213 6-21.36, 0.531-53.1, 0.704-70.4, 0.253-25.3 mg x L(-1). All the five components could be absorbed in blood and excreted quickly. The method established in this paper is rapid and accurate, and could be used for in vivo analysis on preparations containing similar components. The main components in Shaoling Xiaoyin tablets could be absorbed and excreted quickly, and thus suitable to be made into sustained release tablets. Common preparations are required to be taken for 4-6 times a day.

Objective To explore the prognostic value of B-type natriuretic peptide (BNP) for 28-day mortality of elderly patients with non-cardiac critical ill in emergency intensive care unit (EICU). Methods A total of 70 elderly non-cardiac critically ill patients (age≥60 years) in EICU were enrolled, and the blood samples were collected to detect BNP level after the patients' admission to EICU. After 28 days, the mortality was assessed. Results Twenty-two patients (31.4 %) died during 28 days observation, whose BNP levels were significantly higher than that of the survivors [ln BNP: (6.4 ± 1.2) ng/L vs. ( 5. 1 ± 1.5 ) ng/L, P＜ 0. 05] ; BNP level had an area under the receiver operating characteristic curve of 0. 759 (95% CI: 0. 636-0. 882, P＜0.05) for predicting mortality,and the optimal cut point of BNP was 342 ng/L (sensitivity 77.3%, specificity 68.7%).Conclusions BNP level could be a predictor for 28-days mortality for elderly non-cardiac critically ill patients.

Objective To analyze if there are membrane estrogen receptors(ER)in endometrial carcinoma and if there is some relationship between membrane ER and nuclear ER.Methods The cell membrane and total cell ER?and ER?expressions of high and moderate differentiation endometrial carcinoma cells(Ishikawa and HEC-1A cells)were analyzed.Intermittent immunofluorescence dyeing and fluorescent microscopy were carried out with the ceils treated with polyformaldehyde and Triton X-100. Intermittent immunofluorescence dyeing and flow cytometry were carried out with the live cells and the cells treated with Triton X-100 respectively.Results There were fluorescences on the membrane of the Ishikawa and HEC-1A cells which were treated with polyformaldehyde.When the cells were treated with Triton X- 100,the fluorescences were also seen inside the cells.The fluorescence intensity of ER?and ER?in Ishikawa cell membrane(1.09?0.21,1.27?0.33)was stronger than the control,but there were no significant differences(P＞0.05).When treated with Triton X-100,the total cell fluorescence intensity of ER?and ER?in Ishikawa cell(4.21?0.34,4.69?1.96)was stronger than the membrane(P＜0.05). The ER?and ER?fluorescence intensity of HEC-1A cell membrane(1.58?0.13,1.49?0.04)were stronger than the control(P＜0.05).The fluorescence intensity of ER?and ER?of the HEC-1A cell (2.34?0.33,2.52?0.15)was stronger than the membrane also(P＜0.05).The membrane ER?fluorescence intensity of Ishikawa was lower than HEC-1A(P=0.028).But the total cell ER?fluorescence intensity of Ishikawa was higher than HEC-1A(P=0.002).Conclusions There are membrane ER on endometrial carcinoma cells Ishikawa and HEC-1A.The membrane ER must have some similarity to the nuclear receptor.There is no direct correlation between the quantity of the membrane ER and nuclear ER.

Although current synthetic anti-gout drugs have significant therapeutic effects in reducing serum uric acid levels, they have serious side effects such as allergic reactions and liver and kidney damage. Natural products with a wide range of uric acid-lowering and high safety have played a critical role in anti-gout drug discovery and development. This paper reviews the natural products with uric acid-lowering or anti-gout pharmacological effects and the investigation on their mechanisms of action, to provide information for drug discovery and development.
