Fibronectin in normal human breast tissue and in breast tumors were stu-died by immuno-gold silver staining method.In normal mammary tissue,fibronectin was present in basement membrane and stroma but absent in epi-thelial cells.Changed distribution pattern was observed in benign tumorsand malignant tumors,there was an appearance of fibronectin in epithelialcells of acini and ductules and decreased in stroma.The differences wasthat fibronectin decreased in basement membrane in benign tumors and dis-appeared in that of malignant tumors which reflect to some extent the inva-sive nature of tumors.

Natural orifice translumenal endoscopic surgery(NOTES)is a surgical technique which is performed with an endoscope passed through a natural orifice,and then through an internal incision in the viscera(stomach,vagina or rectum)to perform intraabdominal operations.Since the first successful transgastric appendectomy performed by Dr.Rao and Reddy in 2004,NOTES is developing rapidly.The advantages of NOTES include no injury and scar in the body surface;lower anesthesia requirements;faster recovery and shorter hospital stays;avoidance of transabdominal wound infections.NOTES can also be applied to patients who are not suitable for open surgery and lapascopic surgery.NOTES has the potential to revolutionize the field of minimally invasive surgery by eliminating abdominal incisions,however,the safety and efficacy of NOTES still needs to be investigated in lhe future.

Acute lymphoblastic leukemia (ALL) is a common hematopoietic malignancy. The initial complete remission rates of adult ALL reach over 80%, but most of the patients eventually relapse and the long-term survival re-mains poor. This article reviewed advances in the biological features and treatment of adult ALL during the past decade with a view to further improving the survival quality rate of the patients.

Objective: To investigate the mechanism of the effect of Linweidihuang Pills on diabetic neuropathy in rat. Methods: The diabetic rats were induced by alloxan. Serum glucose was tested by glucose oxidase and sciatic nerve sorbitol was determined by GC. Results: After Liuweidihuang Pills,0.5～2g/kg taken orally for 3 months, the level of sciatic nervous sorbitol and serum glucose in rat decreased significantly and the results showed certain dose effect relationship.Conclusion: Liuweidihuang Pills can controll diabetic neuropathy by inhibiting sorbitol biosynthesis.

OBJECTIVE:To control the drug quality risk in drug withdrawal links of hospital pharmacy,and provide reference for the application of quality risk management(QRM)in hospital pharmacy. METHODS:Drug QRM was developed in drug with-drawal links through risk identification,risk assessment,risk control,risk assessment and other steps. Using the incidence of risk factors and reusable rate of withdrawal drug as indexes,related data of before(Jul.-Dec. 2015)and after(Jan.-Jun. 2016)devel-oping QRM in our hospital were compared to evaluate the effect of drug QRM. RESULTS:Determining whether specific storage drugs kept the required storage conditions,whether the numbers of withdrawal drugs counted to minimal packaging and other 5 fac-tors were high-risk factors(the risk score of each factor>4 points);control measures were taken separately for high risk factors, then high-risk factors were reduced to acceptable levels(risk score<4 points). After developing QRM,the incidence of risk factors were reduced than before(reduce 1.35%-6.19%),reusable rate of withdrawal drug was increased(98.64% vs. 86.32%)(all P<0.05). CONCLUSIONS:Developing QRM in drug withdrawal links of hospital pharmacy can reduce the drug quality risk.

With the development of thermal ablation techniques,thermal ablation has been a curative method in the treatment of liver cancer.Preoperative treatment planning as the first step in the thermal ablation process,its core purpose is to lower the complications,ensure tumor-free safety margin after ablation and improve patients' long-term survival.Preoperative treatment planning determines directly the effect of thermal ablation therapy.Preoperative treatment planning is significant to improve the accuracy and sci entific of thermal ablation therapy.Therefore,preoperative treatment planning of thermal ablation for liver cancer has become one of the research focuses in the thermal ablation fields.This review focuses on the treatment planning studies of image-guided thermal ablation for liver cancer in recent years.
