Objective To observe the expression of EGFR,TGF-?,AQP-2 and Bax during development of renal tubules in chick embryo,and explore the role and regulating significance of them. Methods The expression of EGFR,TGF-?,AQP-2 and Bax were observed by immunohistochemistry combined with stereological methods in 36 chicks kidney at 10th-46th incubation stages.The expression intensity of them was analyzed by IPP software. Results The epithelial cells of proximal tubules in chick embryo appeared EGFR immunoreactivity at 26th-46th stages;At 26th-37th stages the epithelial cells of proximal tubules and distal tubules of mesonephros appeared TGF-? immunoreactivity,the epithelial cells of proximal tubules and distal tubules of metanephros appeared TGF-? immunoreactivity at 33rd-40th stages,at 40th-46th stages the epithelial cells of proximal tubules of metanephros appeared TGF-? immunoreactivity but the epithelial cells of distal tubules did not appeare TGF-? immunoreactivity;The epithelial cells of collecting tubules in chick embryo appeared AQP-2 immunoreactivity at 26th-46th stages;The epithelial cells of proximal tubules and distal tubules of mesonephros appeared Bax immunoreactivity at 26th-37th stages,the epithelial cells of proximal tubules of metanephros appeared Bax immunoreactivity at 33rd-46th stages.Images showed the expressions of EGFR,TGF-?(?_1,?_2,?_3)and Bax first displayed up then down,but expression of AQP-2 always displayed up during development of chick embryo.Conclusion Mesonephros of chick embryo has the function of excreting.Degeneration of renal tubules of mesonephros might be related with the excessive expression of TGF-? and Bax.Development,differentiation and maturation of renal tubules and collecting tubules of metanephros might be due to the synergetic expression of EGFR,TGF-?,AQP-2 and Bax.AQP-2 relats to the balance of water during development and maturation of renal tubules in chick embryo.

Gastrointestinal bleeding is a common acute and critical illness that may result in hemorrhagic shock.In conventional concept, sufficient blood transfusion to ensure volume resuscitation was necessary for this emergency condition.With the propose and application of restrictive transfusion strategy in clinical practice, the new concept has been applied in patients with gastrointestinal bleeding.Restrictive transfusion strategy could maintain the perfusion of vital organs with a minimized blood transfusion, and avoiding the coagulopathy and acidosis caused by massive transfusion.This article reviewed the advances in study on gastrointestinal bleeding and restrictive transfusion strategy.

The article reviewed dietary iodine reference intakes for different populations constituted by major countries and international organizations. Lowor high iodine intake can renderrisks to human health and there are different cut-points of iodineexcess for susceptible population. Universal salt iodization demonstratedthe influence on the spectrum of thyroid diseases and its benefitsoutweighrisks since its significant benefits on human potential and quality of life. This article has suggested practical evaluation indicators for certification of sufficient iodine intaketo keep adequate iodine intake for population.

OBJECTIVE:To explore an effective mode and way to quickly train on-the-job pharmacist to become clinical pharmacist in China.METHODS:With the reference to the process and current situation of clinical pharmacist training both domestically and abroad,the background,systems and policies about clinical pharmacist training were compared and the per?sonal working experience of the author was considered,then an efficient mode for domestic on-the-job pharmacist training was put forward.RESULTS&CONCLUSION:On-the-job pharmacist training in China should be carried out in steps,which includes theoretical study and clinical practice,establishment of evaluation system,and writing of scientific papers,only by doing this can we really train the clinical pharmacists in clinical practice,ensure the safe,rational,effective and economic medication and reduce the waste of health resources.

OBJECTIVE To prevent and control hospital cross-infection and hematogenous disease dissemination during oral cavity procedures.METHODS The problems that existed universally in instrument treating processes during oral cavity procedures were taken seriously.The perfect management rules and regulations were established.The instructions of technical operation were carried out strictly.We strengthened own-self occupation protection and implemented the standard prevention isolation principle.We guaranteed oral cavity synthesis method to implement,such as the instrument cleaning,disinfection,and antiseptic quality.RESULTS The hospital infection occurred in the oral cavity procedures could be reduced and avoided fundamentally through implementing infection control measure.The medical safety could be ensured.CONCLUSIONS The personnel standard diagnosing and treating operation of medical care should be established in hospital.The idea of disinfection and isolation asepsis should be enhanced.Own-self occupation protection must be required strictly.It is extremely important to control the infection during the oral cavity procedures.
