OBJECTIVE:To study the anti-inflammatory effect of ethanol extract of Polygonum multiflorum METHODS:To observe the oedema severity and vaso-permeability in inflamed animal and the response of animal to pain induced by acetate acid after the ethanol extract of Polygonum multiflorum had been intragastrically given for 3 days RESULTS:The oedema severity and vaso-permeability were obviously decreased by the ethanol extract of Polygonum multiflorum and this effect could last 4 hours At the large dose,analgesic effect was observed CONCLUSION:The ethanol extract of Polygonum multiflorum exhibits intensive anti-inflammation effect and the mechanism may be related to its immuno-depression effect

OBJECTIVE:To establish a gas chromatography(GC)method for determination of seven residual solvents in clofarabine.METHODS:The capillary column was AT-1301;the carrier gas was nitrogen gas and the detector was FID.By temperature programming was applied for the column temperature with an initial temperature of 40 ℃,which rose to 80 ℃ with an increase rate of 7 ℃?min-1,then rose to 200 ℃(kept at this temperature for 2 min)with the increase rate of 20 ℃?min-1.The injector temperature was 250 ℃ and the detector temperature was 280 ℃.The sample was injected directly for determination of residual levels of methanol,acetonitrile,dichlormethane,t-butyl alcohol,ethyl acetate,n-heptane and acetic acid in 3 batches of clofarabine.RESULTS:All the organic solvents were effectively separated and they showed good linearity within a concentration range(r=0.999 41～0.999 93)with average recovery rate ranged from 96.5% to 102.4%(RSDs of all were less than 4.0%).7 kinds of organic solvents in 3 batches of samples were all up to the standard specified in Chinese Pharmacopeia.CONCLUSION:The method is sensitive,accurate and reliable,and it is applicable for the determination of the residual solvents in clofarabine.

OBJECTIVE:To provide reference for development of PIVAS.METHODS:Based on the practical condition of our hospital,the necessity of PIVAS and several key problems in the implementation process were analyzed.RESULTS & CONCLUSIONS:It is a natural tendency to establish PIVAS for the development of pharmacy.Several problems such as criteria for PIVAS establishment,charge standard,coverage of drug category and medication chronergy need to be further improved.

Cyclooxygenase is the key enzymes mediating prostaglandings release. In recent years, two isoforms of cyclooxygenase, a constitutive cyclooxygenase(COX-1)and an inducible cyclooxygenase (COX-2),have been identified, from which people have known more about gastrointestinal pathophysiology. This article is a review of COX-1 and COX-2 on the distribution, inducement and regulation in gastrointestinal tract and its relation to programmed cell death, tumor, ulcer and Crohn's disease.

Objective:This study aimed to assess the efficacy of comprehensive laparoscopic surgical staging in early-stage ovari-an cancer, and provide references for clinical practice and research. Methods: Electronic databases, such as Embase, Medline, Co-chrane Library, CBM, and CNKI, were searched for studies on comprehensive laparoscopic surgical staging versus comprehensive lapa-rotomic surgical staging. Other sources, such as related references, were also retrieved. The literature was screened according to inclu-sion criteria. Data were extracted from the selected references, and the quality of the included studies was assessed. This meta-analysis was performed using RevMan 5.2 software. Results:A total of 11 studies involving 591 cases were selected, of which 235 cases be-longed to the laparoscopy group and 356 belonged to the laparotomy group. No statistically significant differences were observed be-tween groups in age, body mass index, clinical stage, histological type, and histological grade. The laparoscopy group had less intraoper-ative blood loss, earlier general diet intake, less postoperative complications, and lower postoperative recurrence rate than the laparoto-my group. No statistically significant difference was observed between groups in operation time, pelvic lymph node number (apart from pelvic and para-aortic lymph nodes), mortality. Conclusion:The results of this systematic review show that laparoscopic surgical stag-ing of early-stage ovarian cancer demonstrated staging adequacy and accuracy that were similar to those of laparotomic surgical stag-ing. Based on the principle of minimal invasion and radical treatment to tumor, laparoscopy showed more favorable operative outcomes than laparotomy.

It is nonlinear relationship between breath sounds and respiratory flow rate, thus breath sounds might be a new solution for respiratory monitoring. The envelope of the breath sounds was created firstly. And the linear relationship between the logarithm of envelope and the respiratory flow rate was proved. Then model parameters were derived from every subject using regression analysis. Finally, using these parameters estimated respiratory flow rate was achieved by the logarithm of envelope with 14.9% error. Therefore, respiratory flow rate estimation and respiration monitoring based on breath sounds are feasible.

Objective To discuss the clinical value of procalcitonin (PCT) in guiding antibiotics use in children with severe diseases. Methods The clinical data of patients admitted to intensive care unit from January 2012 to July 2012 were retrospectively analyzed. The patients without antibiotics use before admission and with procalcitonin level less than 0.5 ng/ml on admission were selected. The body temperature, infection indicators and prognosis were compared between patients with and without antibiotics use during hospitalization. Results There was no difference in body temperature, PCT, C-reactive pro-tein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell count (WBC) on admission between patients with and without antibiotics use during hospitalization. The PCT level was increased signiifcantly (P<0.05) on the day of starting the an-tibiotics when compared with that on admission in 60 patients while there was no change in the levels of WBC and CRP. Com-pared with the day of starting the antibiotics, body temperature declined (P<0.05) and PCT level in 56 patients reexamined was decreased (P<0.05) at 3 days after antibiotics use. Two hundred and eleven patients (98.14%) had favorable prognosis. Conclu-sions Monitoring PCT can guiding the clinical use of antibiotics.

Objective To demonstrate the result that progression of disease and prognosis of gastrointestinal cancer patients are correlated with the expression of the cluster and the abundance of lost goodwill target (LGT) fingerprint. Methods To research the period of survival and the time of death, 61 patients treated by SELDI (Surface enhanced laser desorption/ionization-time of flight-mass spectrometer)were involved in. According to the fingerprint spectrum obtained by SELDI and the appearance of fingerprints of LGT, these patients were divided into four groups namely non-peak, single-peak, double-peak, tri-peak and multi-peak groups. By means of Multi-factor analysis of variance and Cox regression analysis of risk, we compare four groups each other so as to find out one group in which patients have the greatest risk of death.Results Among the fingerprint spectrums of patients suffered from gastrointestinal cancer, which were obtained by SELDI, the patients with negative expression of LGT had low risk of death, which were lower than those of single-peak and double-peak groups, especially lower than those of tri-peak and multi-peak groups;the risk of death among the tri-peak and multi-peak groups were much higher than single-peak, the difference had statistical significance (P ＜0.05), and the death rate is rather high. Conclusion Among the serums from cancer patients tested by SELDI, the expression of LGT with tri-peak and multi-peak suggested that patient' s state of illness is about to deteriorate. This kind of fingerprint spectrum can be regarded as positive indicators,and the negative expression of LGT suggested that patient will have a good prognosis with a very low risk of death in the near future.
