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

BACKGROUND:The degradable poly-L-lactic acid (PLLA) biliary-enteric composite stent has been developed. OBJECTIVE:To analyze the solubility and biocompatibility of the degradable PLLA biliary-enteric composite stent. METHODS:Solubility:the PLLA composite stent was implanted into artificial gastric acid to detect the dissolution rate within 12 weeks. Pyrogen test:the PLLA composite stent extracts were injected into the rabbits via ear vein to detect the changes of body temperature. Hemolysis test:the PLLA composite stent extracts, normal saline and distil ed water were added into the rabbit anticoagulant, respectively, to detect the hemolysis ratio. Cytocompatibility test:Caco-2 cel s were respectively cultured in the DMEM medium containing 10%fetal bovine serum, rubber material extracts and the PLLA composite stent extracts, and the cel proliferation was detected at 12, 24, 36 and 48 hours;the lactic dehydrogenase release was detected at 2 days. RESULTS AND CONCLUSION:The PLLA composite stent showed a long stability in vivo, and approximately 80%was dissolved at about 20 weeks. No reactions of pyrogen and henolysis were observed in the pyrogen and hemolysis tests. The PLLA composite stent made no effects on the Caco-2 cel proliferation and lactic dehydrogenase release. In conclusion, the PLLA composite material holds a good solubility and cytocompatibility.

Synchronous bilateral primary breast cancer refers to the simultaneous occurrence of primary cancers in both breasts. The overall morbidity is low. However, with the detection of occult breast cancer increasing recently, it shows an upward trend. The pathogenesis is not yet clear, old age, family history of primary breast cancer, sclerosing adenopathy of precancerous lesions and pathological characteristics of first cancer are currently recognized risk factors. Compared with unilateral breast cancer, prognosis for synchronous bilateral primary breast cancer is poor. Raise the risk awareness of high-risk women, check regularly to find non-palpable lesions as soon as possible. By taking various preventive treatments for patients with high-risk unilateral breast cancer, the incidence of breast cancer can be effectively reduced and the prognosis of patients can be improved. By reviewing the literature at home and abroad, it systematically expounds the risk factors, histopathological features, prognosis and preventive treatment of synchronous bilateral breast cancer.
