Objective To investigate traditional Chinese medical emotional intervention on the cognition function of senile patients after abdominal surgery. Methods Seventy senile patients having elective abdominal operation were randomized into intervention group and control group, 35 cases in each group. The control group received routine peri-operative nursing, and the intervention group was given routine peri-operative nursing and emotional intervention based on the theory of traditional Chinese medicine. The cognition function was evaluated with mini-mental state examination (MMSE) on preoperative day 1, postoperative day 3 and 7, and serum S100βprotein level was detected before operation and on postoperative day 7. Results (1)Time for recovery from general anesthesia in the intervention group was much shortened as compared with that of the control group(P<0.05). (2)On postoperative day 3, the incidence of postoperative cognitive dysfunction(POCD) was much lower than that of the control group(P<0 . 0 5), and on postoperative day 7 , the difference of POCD incidence was insignificant between the two groups(P>0.05). (3) On postoperative day 7, serum S-100β protein level in the two groups was increased as compared with that before treatment(P<0.05), but the difference between the two groups was insignificant(P>0.05). Conclusion Traditional Chinese medical emotional intervention has an effect on shortening time for recovery from general anesthesia and decreasing POCD incidence, but has no effect on POCD incidence and serum S100βprotein level on postoperative day 7.

OBJECTIVE:To optimize the clarification and purification technology of Perillae folium extract. METHODS:The effects of 3 clarification and purification methods as chitosan flocculation clarification,ZTC 1+1-Ⅱflocculation clarification,water precipitation on retention rate of total flavonoids and removal rate of solid of Perillae folium extract were compared to screen suit-able clarification and purification technology. With the retention rate of total flavonoids and removal rate of solid as comprehensive evaluation index,single factor and orthogonal test were designed to investigate the optimal value of concentration proportion,the amount of the flocculant,flocculation temperature and whisking speed in optimal clarification and purification method. RESULTS:Among 3 methods,the chitosan flocculation clarification was the best with concentration proportion of 1∶4,chitosan of 1.0 g/L, flocculation temperature at 60 ℃,whisking speed of 100 r/min,whisking time of 4 min,standing time of 12 h. Under the condi-tion of optimal processing,the retention rate of total flavonoids was (85.1 ± 0.75)%,and the removal rate of solid was (24.6 ± 1.33)%(n=5). CONCLUSIONS:Chitosan flocculation can be used to effectively remove the impurity of Perillae folium extract, and optimized clarification and purification technology is stable and feasible.

This study was designed to construct THY1 eukaryotic expression plasmid and assess its effects on epithelial ovarian cancer cell line SKOV3. The gene fragment coding for THY1 was inserted into pcDNA3.1(+) for constructing the recombinant plasmid pcDNA3.1(+)-THY1. The eukaryotic expression plasmid was analyzed by PCR, restriction endonucleases digestion and DNA sequencing. The recombinant plasmid pcDNA3.1(+)-THY1 was transfected into SKOV3 cells by liposome protocol. The experimental cells were classified into three groups: SKOV3-THY1, SKOV3-Null and SKOV3. The pcDNA3.1(+)-THY1 has been transfected into SKOV3 cells by RT-PCR and immunohistochemistry. The cell inhibitory rate of SKOV3-THY1 (56.6% at the fifth day) was higher than that of SKOV3-Null (12.5%), there was significant difference between them (P<0.05). The ratios of G1 phase of SKOV3 cells after transfection were increased and the ratios of S phase were decreased significantly. There was significant difference between SKOV3-THY1 and SKOV3-Null or SKOV3 (P<0.05), but there was no significant difference between SKOV3-Null and SKOV3 (P>0.05). We have constructed the recombinant plasmid pcDNA3.1(+)-THY1 sucessfully. THY1 transfection can inhibit the growth of SKOV3 cells in vitro.
