Objective To discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

Background Pupillary light reflex has been widely used in the diagnosis and evaluation of visual system and nervous system diseases.However,in animal experiments,functional evaluation of the visual system and nervous system needs more advanced technology and are affected by many factors.Objective This study was to explore the use of the dynamic pupillometer in evaluating pupillary light reflex and to discuss the influence of brightness of stimulate on relevant curve parameters in C57BL/6 mouse.Methods Ten healthy SPF male C57BL/6 mice were collected in this experiment.White light of five luminance levels (2,8,32,128,256 cd/m2) was used to stimulate the mice following a 2-hour dark adaptation.The stimulation was given at the 60-second intervals,for a duration of 100 ms at every stimulation.An infrared camera and video capture card were used to capture digital images during the measuring process in a scotopic environment,at a speed of 60 frames per second.Measuring outcome was saved in the*.AVI format.A software that was developed by our group was used to determine pupil diameter and output pupillary light reflex curve offline.Pupil initial diameter (R1),constriction amplitude (CA),constriction velocity (CV),latency (T1),time for maximum velocity (T2),time for maximum constriction (T3),time for maximun con-striction to 10.1％ R1 re-dilation (RT)and re-dilation velocity (RV)were assessed,and the correlations between luminosity and measuring parameters were analyzed using the Spearman rank correlation.The use of animals followed the Regulations for thd Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results R1 values showed no statistically significant difference among the 5 different luminosity groups(F=1.117,P=0.361).A positive linear correlation was found between stimulating luminosity and CA(r=0.508,P＜ 0.01),but negative correlations were seen between stimulating luminosity and CV or RV (r=-0.625,-0.609,P＜0.01).T1 and T2 values in the 5 different luminosity groups were not statistically significant (F =0.202,P =0.936 ; F =1.584,P =0.195).The different levels of stimulating luminosity showed positive linear correlations with T3 and RT values (r =0.791,0.609,P＜ 0.01).Conclusions The dynamic pupillometer can quantitatively measure the pupillary light reflex of C57BL/6 mice.The pupillary light reflex dynamic curve parameters of mouse were affected by stimulus luminosity levels.These outcomes offer a basis for the application of the dynamic pupillometer system for measuring pupillary light reflex in animal models.

OBJECTIVETo develop an HPLC method for fingerprint determination of the astragalosides injection.

METHODAnalyses were carried out at 25 degrees C on a Zorbax SB-C18 column (4.6 mm x 250 mm,5 microm). Mobile phase A was water, and B was acetonitrile. The analysis followed a linear gradient program. Initial conditions were 15% B; 0 to approximately 65 min, changed to 60% B. The flow rate was 0.8 mL x min(-1). The drift tube temparature of the ELSD was 105 degrees C, and gas flowrate was 2.7 L x min(-1).

RESULTThe RSD of relative retention time of the common peaks in the plant material, the extract and the injection fingerprints was less than 0.1%, and there was good similarity among 10 batches of samples.

CONCLUSIONThe method was reliable and simple which could be used for quality control of the injection.

The stable and controllable quality of decoction pieces is an important factor to ensure the efficacy of clinical medicine. Considering the dilemma that the existing standardization of processing mode cannot effectively eliminate the variability of quality raw ingredients, and ensure the stability between different batches, we first propose a new strategy for Chinese medicine processing technologies that coupled with individuation processed and cybernetics. In order to explain this thinking, an individual study case about different grades aconite is provided. We hope this strategy could better serve for clinical medicine, and promote the inheritance and innovation of Chinese medicine processing skills and theories.
