The objective of this study was to develop a method for the determination of taxol injection using near infrared transmission spectroscopy, turning out redetermination for injection from hospital pharmacy before using. Near infrared spectra (NIR) in the range of 12 000 approximation 4 000cm(-1) were recorded for the taxol injection manufactured during recent 24 months with different time. Calibration models were established using the partial least squares (PLS). Comparing different spectra pretreatments methods, dimension and spectra range, The study showed that spectra information cab be extracted thoroughly by delete a line method with dimension 6, spectra range 9002.5 approximately 4597.7cm(-1) ,standard error of the calibration sets(SEC) 0.035 and standard error of the prediction sets(SEP) 0. 059. Percent of prediction sets sample is less than +/- 2%. Results indicate that near infrared transmission spectroscopy method can be used to rapidly analyze the frequent and important drugs from hospital pharmacy.

Arachidonic acid, as an important polyunsaturated fatty acid, is identified as potential food additives or pharmaceuticals for their biological activities. In recent years, arachidonic acid production by Mortierella alpina is becoming a research highlight. The prophase relevant researches focused on the mutagenic breeding and fermentation optimization. With the depth of investigation, the advancement concerning pathway for the biosynthesis of arachidonic acid in Mortierella alpina has been made. In this review, we summarized the prophase work briefly. Mainly, we discussed the biosynthesis pathway of arachidonic acid, the key enzymes, the construction of transformation system and the genetic modification. In addition, the prospect of microorganism arachidonic acid production is put forward.

In the present study we explored the different patterns of volumetric atrophy in hippocampal subregions of patients with left and right mesial temporal lobe epilepsy with hippocampal sclerosis (TLE-HS). Meanwhile, the memory impairment patterns in Chinese-speaking TLE-HS patients and potential influencing factors were also determined. TLE-HS patients (21 left and 17 right) and 21 healthy controls were recruited to complete T2-weighted imaging and verbal/nonverbal memory assessment. The results showed that both left and right TLE-HS patients had overall reduced hippocampal subregion volumes on the sclerotic side, and cornu ammonis sectors (CA1) exhibited maximum atrophy. The verbal memory of left TLE-HS patients was significantly impaired (P < 0.001) and was not associated with the volumes of the left hippocampal subregions. Verbal or nonverbal memory impairment was not found in the patients with right TLE-HS. These results suggested that the atrophy of hippocampal subregion volumes cannot account for the verbal memory impairment, which might be related to the functional network.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.
