This study is to establish an UPLC fingerprint of Resina Draconis from different manufacturers, which can provide a comprehensive evaluation for its quality control. The analysis was performed on a Phenomenex Kinetex 2.6 μ C18 100A column by agradientelution program with acetonitrile-water as mobile phase at a flow rate of 1.7 mL x min(-1). The column temperature was 40 degrees C and the detection wavelengthwas 280 nm. The fingerprints of 18 batches of Draconis Resina were further evaluated by chemometrics methods including similarity analysis (SA), hierarchical clustering analysis (HCA) and principal component analysis (PCA). As a result, there were 15 common peaks, 13 of which had been identified by LC-Q-TOF MS, and the similarity degrees of 15 batches of the samples was more than 0.9, and the samples were divided into 4 clusters by their quality difference. The method is reproducible, simple and reliablethat it can be used for quality control and evaluation of Resina Draconis from different manufacturers.

This article discussed ZHU Lian's contributions to acupuncture-moxibustion scientific research from three aspects: building the scientific thought of "new acupuncture-moxibustion", constructing the first domestic acupuncture-moxibustion institution and opening the door to modern acupuncture-moxibustion scientific research. ZHU Lian's visionary thought of "new acupuncture-moxibustion" has influenced the following researchers till now. She established the acupuncture-Moxibustion therapeutic institute affiliated to the Ministry of Health, set up the acupuncture-Moxibustion research platforms and teams and made research cooperation. She firstly carried out acupuncture-Moxibustion clinical and basic scientific research, which started the acupuncture-Moxi- bustion scientific research in China. ZHU Lian is the Pioneer of Chinese acupuncture-Moxibustion scientific research.

Objective To observe the parameters and effect of endocardial pacing by steel wire electrode cardiac puncture on heart with normal beat in living animal, and evaluate its safety.Methods After anaesthesia and thoracotomy in 6 living dogs with normal heart beat, the pericardia were excised. Steel wire electrodes with annular or hook tips were used respectively at right ventricular 4 corresponding spots to perform cardiac puncture endocardiac pacing (each dog experienced 8 times of puncture); the time from puncture to effective pacing, pacing parameter and puncture complication (time and quantity of bleeding) of each electrode at each spot were recorded. Finally, the two types of electrode completed 24 times of manipulation respectively; the data collected of the two types were compared. Results The cardiac pacing successful rates in the two groups were 100%; the time taken from the beginning of heart puncture to effective pacing in annular tip group was less than that in hook tip group, but the time difference between the two groups showed no statistical significance (s: 18.4±2.3 vs. 19.6±4.1,P > 0.05). The parameters of pacing in the annular tip group, such as operation time (s: 18.4±2.3 vs. 19.6±4.1), the threshold value of pacing (V: 2.1±0.2 vs. 2.2±0.8), the amplitude of R wave sensed (mV: 11.3±3.2 vs. 12.6±4.1) and the impedance of electrode (Ω: 674.2±89.7 vs. 668.5±101.3) were not significantly different compared with those in the hook tip group (allP > 0.05). Either after puncture or after the electrodes were taken out, the time of bleeding [after puncture (minutes): 4.4±2.3 vs. 4.5±3.1, after the electrodes taken out (minutes): 4.1±2.2 vs. 4.8±2.5] and the volume of bleeding [after puncture (mL): 2.8±2.4 vs. 3.2±3.5, after the electrodes taken out (mL): 3.3±1.7 vs. 3.5±2.6] were not significantly different between the two groups (allP > 0.05).Conclusions In living dogs with normal heart beat, the manipulation and function of endocardiac pacing by cardiac puncture with either steel wire annular or hook tip electrode are well and effective, and the performance is simple and safe without any serious myocardial injury and complication. Thus, it is helpful to quickly establish efficient endocardiac pacing in emergency cases.

To provide accurate information on geographic distribution of crude drug Sailonggu in the plateau, we identified zokor species (Eospalax spp.) in Qinghai-Tibet Plateau using molecular methods. Based on the mitochondrial cytochrome B (cytb) gene sequences, we then extracted haplotypes from these sequences and reconstructed phylogenetic trees for the haplotypes using both maximum likelihood (ML) and Bayesian inference (BI) methods. Based on the trees, the species of each sample were determined. Five hundred and three samples from 35 populations were sequenced and their whole cytb sequences (1140 bp) were obtained. From these sequences 150 haplotypes were detected, in which, 126 were Eospalax baileyi, 20 were E. cansus, and 4 were E. smithi of the 35 populations, 28 were E. baileyi type, 5 were E. cansus type, and the remaining 2 were mixed of E. baileyi + E. cansus (DT2) and E. baileyi + E. smithi (ZN3). The results showed that, the regions around the Qinghai lake and near the upper stream of Yellow River started at Guide could be viewed as the producing area of authentic Sailonggu, and also, the cytb gene is a powerful molecular marker to determine the species of zokors as well as for the authentication of geographic distribution of Sailonggu.

Objective To investigate the symptoms on depression in patients with viral hepatitis. Methods A cross-sectional study was conducted among the patients with viral hepatitis in infectious diseases Hospital of Taiyuan. The questionnaire included a Eysenck Personality Questionnaire, self-rating depression scale (SDS) , and a self-designed one related to information regarding general conditions of the disease and social support. Results (1)Depression symptom prevalence rate among chronic viral hepatitis patients was 54.7% (116/212). (2) Factors as age, occupation, education, confirmed time, number of recurrence and anti-virus treatment, self-confidence on recovery, satisfaction on the surrounding environment etc. that might be associated with depression. (3) The severity of depression was significantly negative correlation with social support scores, objective support scores, subjective support scores (r=-0.262, P=0.000;r=-0.228, P=0.001 ; r=-0.270, P=0.000). (4) There was positive correlation noticed between severity of the depressive disorder and Eysenck Personality two dimensions scores, while the scores of introversion and extroversion scores were negatively correlated (r=-0.330, P=0.000) but positively correlated to the emotional stability scores (r=0.309, P=0.000). Conclusion (1) Patients with hepatitis showed symptoms of depression to a certain degree. (2) Factors as age, occupation, education, economic situation, confirmed time of diagnosis, number of recurrence and anti-virus treatments, confidence on recovery, satisfaction on the surrounding environment might be associated with symptoms of depression. (3) There was positive correlation between severity of depressive and Eysenek Personality two dimensions scores but the scores of introversion and extroversion scores were negatively correlated.
