Liver has great ability in regeneration,and liver regeneration is closely related to the prognosis of patients who received liver surgeries.The mechanisms of liver regeneration include biochemical theory and hemodynamic theory.Portal perfusion with moderate pressure is an important factor for starting liver regeneration.Hepatic artery buffer response,fluid shear stress and gasotransmitter play important roles in the liver regeneration.Learning the mechanisms of hemodynamic signal is of great importance for the treatment of liver diseases.

Cooperation networks of nursing techniques were constructde by way of perspective practice so as to enhance the quality of nursing critical cases, the success rate of emergency treatments and patients' life quality. The measures included training in techniques for nmsing critical cases, making the rounds of wards and consultations, and enlarging the scope ofthe cooperation networks. Quantification methods were introduced into management, networks of critical case assessment were used in managing patients, and the system for assessing training in techniques for nursing critical cases was used in managing nursing personnel, thus improving the quality of the nursing pensonnel, ensuring the rational allocation of human resources and promoting the enhancement of the hospital's medical quality and its social and economic benefits. It is therefore not difficu1t to see that the cooperation networks are of application and dissemination value.

Antiplatelet therapy is commonly used for the secondary prevention of embolic stroke of undetermined source (ESUS). However, the embolic source of ESUS is extremely heterogeneous, and the effect of antithrombotic therapy is different. This article describes the etiology and secondary prevention research progress of ESUS, in order to provide reference for clinical diagnosis and treatment.

The paper gives an account of the basic methods for assessing the intrinsic quality of patient nursing by nursing procedures. These include: ①monitoring the accuracy of nursing assessment via evaluating the integrity of patients health; ②evaluating the soundness of nursing diagnosis via analyzing and judging the individuality of patients; ③evaluating the rationality of nursing goals and the appropriateness and operability of nursing measures through patients changes in behavior, function, cognition and emotion; and ④evaluating the timeliness and cyclicity of nursing result assessment through the improvement of patients overall conditions. The paper also analyses the problems involved in employing nursing procedures and countermeasures, pointing out that timely transformation of the nursing management model can markedly enhance the intrinsic quality of nursing.

This paper summarized nursing experience of 11 patients with refractory or relapsed neuroblastoma who developed CAR-T adverse reaction after receiving the transfusion.Nursing key points included:close monitoring of changes of vital signs,especially body temperature and blood pressure;observation of changes of skin,avoiding scratching when skin rash occurred,and daub calamine lotion was applied;strict recording input and output volume of 24 hours,ensuring patency of venous catheters and constant infusion of liquid,observing changes of urine volume and color;strengthening prevention of infection,strict operation of antiseptic technique,protective isolation when moving in laminar flow clean room;monitoring changes of face,breathing,blood oxygen and so on.Through careful treatment and nursing care,the treatment of children was ensured.

Objective For bioequivalence test of the consistency evaluation of generic drug products,providing a reference of varieties of biowaiver.Methods Based on Human bioequivalence test waiver guidelines (draft),on condition that first drug of the consistency evaluation,to introduce and conclude briefly the standards of biowaiver and varieties of biowaiver in FDA,WHO and EMA.Results Contrast to FDA,there are 59 varieties applied for the waiver and 19 varieties not applied for the waiver in the 289 varietie;compared to WHO,10 drugs are exempted and 1 grug is exempted in EMA.Conclusion At present,the specific list of drugs are not published of biowaiver in our country,the pharmaceutical companies should compare and consult revelant standards and specific drugs in China and abroad,to speed up the progress of the consistency evaluation.

English training is important for young doctors＇ career development in general hospital.The stagewise English training mode of Beijing Tiantan Hospital of Capital Medical University was introduced.By summarizing the experience of five years trial,viewpoints were brought forward that hospital English training in radiological department of general hospital should adopt a stagewise mode,create an English communication atmosphere,show the special feature of department and combine with clinical daily work.

Objective To study the anatomical structure and the distribution of the right posterior sectional Glissonean pedicle so as to provide the anatomical basis for liver resection of the right posterior section.Method By studying the morphological features of the right posterior sectional Glissonean pedicle through peeling and dissecting 20 adult corpses without liver pathological.Result In 95％ of the right posterior sectional Glissonean pedicles there were shared branches.The angle between the GRL/GRA was 81.4° ± 13.8°.In 30％,the right posterior sectional Glissonean pedicle presented as a Y or a V.In a Y shaped,the angle between G6/G7 was 71 ° ±3.92°.The shapes of 70％ of the right posterior sectional Glissonean pedicle presented as a C.The number of branches at the tertiary level was between 3-8.Conclusion The distribution of the right posterior sectional of the Glissonean pedicle did not entirely fit the description of Couinaud's segments.Obvious individual differences existed.Under this circumstance,understanding the anatomy of the right posterior sectional Glissonean pedicle before carrying out partial hepatectomy would be helpful in reducing surgical risks and postoperative complications.
