Objective To investigate the protective effct of Panax quinquefolium saponins from steams and leaves(PQS)on focal cerebral ischemia injury in rats and its mechanisms. Methods Wistar rats were randomly divided into sham operation group,model control group,nimodipine group and two PQS groups,in which PQS of 100 and 50 mg/kg was intragastrically administered. Focal cerebral ischemia model was established by middle cerebral artery occlusion (MCAO)in rats, via string ligation of artetia carotis interna. The content of malondicldehy de(MDA) was determined by thibabituric acid ( TBA ) test, the activity of lactate dehydrogenase ( LDH ), superoxide dismutase (SOD)and the content of lactic acid(LA) were detected by chemical colorimetry test in cerebral tissues. Results PQS( 100,50mg/kg)could significantly decrease the content of LA、MDA and increase the activity of LDH、SOD. Conclusion The protective mechanism of PQS on focal cerebral ischemia injury may be related to reduce acidosis, anti-free radical and resist oxidative damage.

Plant growth retardant as one of plant growth regulator can inhibit the cell division, elongation and growth rate in shoot apical meristem (SAM), which can be reversed by gibberellin regulate the product of photosynthesis transfer to the root and rhizome part. As commonly used plant growth retardant, paclobutrazol, uniconazole, chlorocholine chloride, mepiquat chloride, choline chloride and daminozide are used to promote the growth of root and rhizome, call as "zhuanggenling", "pengdasu", "pengdaji" etc. Single or recombination of plant growth regulator is registered as pesticide, and called as pesticide "zhuanggenling" in this paper. Growth regulator which registered as a foliar fertilizer or fertilization was called agricultural fertilizer "zhuanggenling" in this paper. The author investigate the usage of "zhuanggenling" in the root and rhizome of medicinal plants cultivation from 2012 to 2014 in Sichuan province, Huangyuan town, Mianyang (Ophiopogonis Radix); Pengzhou Aoping town (Chuanxiong Rhizoma); Pengshan Xiejia town (Alismatis Rhizoma); Jiangyou Taiping town and Zhangming town (Aconiti Lateralis Radix Praeparata); Yunnan Wenshan (Notoginseng Radix et Rhizoma); Henan province, Wuzhidafeng Town (Rehmanniae Radix, Achyranthis Bidentatae Radix, Dioscoreae Rhizoma); Gansu Min county (Codonopsis Radix, Angelicae Sinensis Radix); Gansu Li county (Rhei Radix et Rhizoma). The result showed that "zhuanggenling" were applied in the most medicinal plant cultivation except Rhei Radix et Rhizoma. It has been applied widespreadly in Ophiopogonis Radix, Alismatis Rhizoma, Achyranthis Bidentatae Radix, Codonopsis Radix; Rehmanniae Radix, commonly in Angelicae Sinensis Radix application, and occasionally in Chuanxiong Rhizoma, Aconiti Lateralis Radix Praeparata, Notoginseng Radix et Rhizoma and Dioscoreae Rhizoma. In 53 collected sample from plantation areas, fifteen (28%) were pesticide "zhuanggenling", thirty-eight (72%) were pesticide "zhuanggenling". UPLC analysis results showed that 38 farmers fertilizer "zhuanggenling" content of 6 kinds of plant growth retardant. It is regarded that fertilizer "zhuanggenling" was dominant in medicinal plant cultivation, and that the plant growth retardant is added widespreadly in farm fertilizer "zhuanggenling". All evidence proves conclusively that "zhuanggenling" have been used in the proper way, whereas some others have been misused or even abused in the use regarding to type, number, use frequency. The root or rhizoma are increased to 20%-200%. But there is lack of evaluation to appraise the quality of medicinal materials from the aspects of research or industry. "zhuanggenling" has become a important Chemical control material besides fertilizer, insecticidal sterilization of pesticide

Objective:To analyze the intervention effect of a successfully created platform“intelligent interactive software for drug monitoring warning” on the decrease of medication errors and adverse drug events,and the increase of the drug treatment level. Meth-ods:The intensive care unit ( ICU) of our hospital was selected as the experiment group, and the ICU of the other two hospitals was used as the contrast group. During the first 18 months, both groups were without intervention. During the latter 18 months, the plat-form was used in the experiment group, and the clinical pharmacists employed alerts of the system in the practice of interaction with doctors to correct the medication errors. No intervention was performed in the contrast group. In addition, all adverse drug events in both groups were surveyed. Results:During the first period, 50 preventable adverse drug events were discovered with the incidence of 6. 8% in the experimental group. During the second period, the correct rate of the alerts was 97. 7%. Through the effective interven-tion,the alerts and their percentage in the prescriptions were from the maximum of 68 and 1. 1% to the minimum of 6 and 0. 1%. To-tally 17 preventable adverse drug events were found with the incidence of 2. 4% after the intervention. The decline was significant, 848 991 yuan of hospitalization expenses was saved, and 294 days of the length of stay were shortened. There was no change in the contrast group, and there was no change in unpreventable adverse drug events in the two groups before and after the intervention. Conclusion:The intelligent interactive software for drug monitoring warning can examine many sorts of medication errors,and decline the inci-dence rate of preventable adverse drug events in ICU. However, it needs to continuously improve the intelligence. Clinical pharmacists need to master the relevant conditions of patients to detect the irrational drug use based on the clinical practice for each patient.

Objective To explore the effects of lycium barbarum polysaccharide (LBP) on restraining the mouse pancre?atic cancer cells LTPA by the polarization of macrophages to type 1 macrophages (M1). Methods LTPA tumor model of the subcutaneous CB-17SCID mice was constructed. Model mice were randomly divided into tumor-bearing model group (n=10) and LBP treatment group (n=10). The LBP treatment group was fed 10mg/kg LBP every day, and the tumor-bearing model group was fed the same dose of normal saline. The same amount of macrophages Raw264.7 was randomly divided into the control group and experimental groups (different concentrations of LBP). MTT assay was used to detect the optical density (OD) of Raw264.7 in experimental groups and control group. ELISA was used to detect the levels of the interleukin (IL)-12 and IL-10 in experimental group (LBP was 100 mg/L) and the control group. Flow cytometry was used to test the levels of the membrane protein CD16/32 and CD206 in experimental group (LBP was 100 mg/L) and the control group. The tumor mass was weighted and the volume was calculated after three weeks. The effects of LBP on the growth of subcutaneous tumor were detected. HE staining and KI-67 staining were used to detect the microscopic changes of tumor and the proliferation of the LTPA. Results The dose of 100 mg/L LBP can promote the growth of the macrophages Raw264.7 (P<0.01), and induced the high expression of CD16/32 and low expression of CD206, high secretion of IL-12 and low secretion of IL-10. The weight, volume of the tumor and the expression of KI-67 were significantly lower in experimental group than those in the con?trol group (P<0.01). The microscopic necrosis area range of tumor was larger than that of control group. Conclusion The LBP has the effect of restraining LTPA by the polarization of macrophages to M1.
