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 establish microbiological method for determining biotin in foods and feeds. Methods: Using biotin dependent microorganisms Lactobacillus plantarum(ATCC 8014), the biotin content was detected indirectly by the growth of cultrued bacteria spectrophotometrically.Results: The detection limit was 0.03 ng. The relative standard deviations(RSD) of within and between run assays were 2.2%-3.8%,2.1%-5.3% respectively. The recovery of added biotin was 93.4%-104.6%, and RSD was 3.1%-4.1%. Conclusion: This assay is sufficiently accurate and repoducible for determining biotin in foods and feeds.

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.

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.

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.

OBJECTIVETo discuss the clinical effect on swelling and pain after total knee arthroplasty treated with acupoint massage, mild moxibustion and routine detumescence.
METHODSOne hundred and twenty patients of knee osteoarthritis (KOA) after total knee arthroplasty (TKA), were randomized into an observation group and a control group, 60 cases in each one. In the control group, after TKA, the routine detumescence was applied, including elastic bandage compression, the operated limb raising exercise, knee joint braking, local ice compress, intermittent pneumatic compression, active ankle pumping and quadriceps contraction exercise, continuous passive mechanical exercise, using stretch socks, oral administration of rivaroxaban tablets, 10 mg, once a day, continuously for 21 to 24 days. In the observation group, on the basis of the routine detumescence as the control group, 1 h after operation, acupoint massage was done at Zusanli (ST 36) and Sanyinjiao (SP 6) till soreness and distension presented, twice a day; 48 h after operation, mild moxibustion was intervened at Zusanli (ST 36) and Sanyinjiao (SP 6), avoiding burning pain, once a day, continuously till the 7th day after operation. Before and after operation, the limb swelling condition and the scores of visual analogue scale (VAS) and HSS (hospital for special surgery) knee joint function were observed in the patients of the two groups.
RESULTSOn the 1st, 3rd, 5th, 7th and 14th days after operation, the swelling incidence in the observation group was apparently lower than that in the control group (P < 0.05, P < 0.01). On the 1st, 3rd, 5th and 7th days after operation, the scores of VAS in the observation group were lower than those in the control group (all P < 0.05). On the 7th and 14th days after operation, the scores of HSS in the observation group were better than those in the control group (all P < 0.05).
CONCLUSIONThe combined intervention of acupoint massage and mild moxibustion reduces the incidence of lower limb swelling, alleviates pain and promotes knee joint function recovery of TKA and the effects are better than those achieved by the simple routine detumescence therapy.
