Objective To investigate the difference of clinical characteristics and treatment outcome between pituitary apoplexy with and without inducing factors. Methods The clinical characteristics and treatment outcome between 12 pituitary apoplexy with inducing factors and 30 pituitary apoplexy without ones. Results Compared with the patients of pituitary apoplexy without inducing factors, the patients of pituitary apoplexy with inducing factors more frequently occurred visual dysfunction(P=0.020) and visual field defection(P=0.046), and the diagnosis of pituitary apoplexy was also delayed in the latter (P=0.015). Conclusion Inducing factors of pituitary apoplexy often aggravated the apoplexy, delayed its diagnosis and treatment due to atypical clinical symptoms, and caused worse restoration of visual function. Headache patients with abrupt visual deterioration should be considered suffering from pituitary apoplexy.

Objective To explore effect of application of quality control circle (QCC)on improving the correct rate of hand hygiene (HH)among health care workers (HCWs)in intensive care unit(ICU).Methods QCC activity group was set up,the activity theme was established,correct rate of HH among HCWs in March 2014 (pre-inter-vention group)was monitored,the causes of incorrect HH behavior were analyzed,goals were set;from May 2014, QCC activities were initiated,correct rate of HH between before performing QCC activities and September 2014 (post-intervention group)was compared.Results 834 and 900 times of HH among HCWs were investigated before and after performing QCC activities,the number of correct HH before and after QCC activities were 360 and 714 re-spectively,correct rate of HH after implementing QCC was higher than before QCC activities (79.33% vs 43.17%,χ2 =240.19,P <0.05).The correct rate of HH among HCWs of this ICU and HCWs engaging in ad-vanced studies in this ICU after implementing QCC activities were both higher than before QCC activities (χ2 =264.44,6.36,respectively,both P <0.05).The main incorrect HH before and after QCC was non-implementation of HH indication.Conclusion Application of QCC activities for the management of HH among HCWs can effec-tively improve the correct rate of HH among HCWs in ICU.

Objective To evaluate the predictability of ablated depth in photorefractive procedures by Zeiss MEL80 and VISX Star S4 excimer laser.Design Prospective,comparative case series.Participants 168 eyes of 84 people with myopia and cylinder.Main Outcome Measures Corneal thickness and ablated depth.Methods The thickness of cornea by Zeiss MEL80 and VISX Star S4 were measured by anterior segment OCT.The actuality ablated depth and calculated depth were compared.Results There were no significant differences between actuality ablated depth and calculated depth in Zeiss MEL80.And in VISX Star S4,the actuality ablated depth was more than calculated depth.Linear regression of changes in ablated depth on myopia and cylinder yielded the following formulaus:△ablated depth(VISX Star S4)= 2.324 *|myopia|+ 5.270 *|cylinder|-6.772.Conclusions Different excimer laser has different changes between actuality ablated depth and calculated depth.To guarantee the safety of LASIK,Ophthalmologists should know the characteristics of the excimer laser.

Objective To explore the effects of low serum-albumin on maternal and neonatal outcomes in severe pre-eclampsia. Methods Two hundred and thirty-three women with severe preeclampsia admitted to our hospital from Jan. 2000 to Mar. 2006 were retrospectively investigated and were divided into two groups according to the serum-albumin level: low serum-albumin group (Group A, n= 133) and normal serum-albumin group (Group B, n=90). Maternal and fetal outcomes were compared between the two groups. Results The proportion of women with abnormal retention of fluid (6.8%, vs 0), elevated liver enzymes (60.9% vs 38.9%) renal involvement (30.1% vs 11.1%) and complications (23.3% vs 11.1%) (placental abruption and postpartum hemorrhage) in group A were significantly higher than those in group B (all P<0. 05). Birth weight in group A was lower than that in group B[(2192. 78±795. 31) g vs (2454. 92±776. 24) g, P<0. 05] and neonatal mortality in group A was higher (26.0%vs 13. 6%, P<0. 05). Conclusions Severe pre-eclampsia with low serum-albumin is associated with severe maternal and neonatal outcomes. Appropriate termination of pregnancy should be considered following adequate and careful assessment of maternal and fetal well-being in order to improve perinatal outcomes.

Quantitative NMR (qNMR) is a technology based on the principle of NMR. This technology does not need the references of the determined components, which supplies a solution for the problem of reference scarcity in the quantitative analysis of traditional Chinese medicines. Moreover, this technology has the advantages of easy operation, non-destructiveness for the determined sample, high accuracy and repeatability, in comparison with HPLC, LC-MS and GC-MS. NMR technology has achieved quantum leap in sensitivity and accuracy with the development of NMR hardware. In addition, the choice of appropriate experimental parameters of the pre-treatment and measurement procedure as well as the post-acquisition processing is also important for obtaining high-quality and reproducible NMR spectra. This review summarizes the principle of qHNMR, the various experimental parameters affecting the accuracy and the precision of qHNMR, such as signal to noise ratio, relaxation delay, pulse width, acquisition time, window function, phase correction and baseline correction, and their corresponding optimized methods. Moreover, the application of qHNMR in the fields of quantitation of single or multi-components of traditional Chinese medicines, the purity detection of references, and the quality analysis of foods has been discussed. In addition, the existing questions and the future application prospects of qNMR in natural product areas are also presented.

This paper was aimed to study the method of rapid determination of total flavonoids in Chrysanthemum of different processing methods by near infrared spectroscopy (NIRS). The Chrysanthemum was dried by three different processes. The three methods were directly drying, drying after steamed and drying after fry, respectively. The determination of total flavonoids in Chrysanthemum by different processing methods was produced by using UV-Vis spectrophotometry. Collecting the NIRS spectra of Chrysanthemum, the quantitative analysis model of total flavonoids content in Chrysanthemum of different processing methods was established by partial least square (PLS) and the model was validated. The correlation coefficient (R2), the root-mean-square error of calibration (RMSEC) and the root-mean-square error of prediction (RMSEP) were 0.996 19, 0.104 and 0.168, respectively. The correlation coefficient of predication (r) was 0.979 3 which state that the prediction was accurate. The method of NIRS had the advantage of fast determination, simple operation and high accuracy of prediction, and could be used for rapid determination of total flavonoids content in Chrysanthemum of different processing methods.
