The curriculum for general practitioner training does not include much knowledge on medical humanities except for medical ethics,which can not meet the requirement of general practitioners' defined duty.This article analyzes the necessity of adding social psychological skills to the training and assessment of general practitioners from the following aspects of the nature of general practitioners' duty,and the disadvantages of medical humanities education in current Chinese medical universities.Then the proposition of this system is also presented.

Objective To investigate the distribution and duration of abnormal blood glucose level in SGA infants. Methods Blood glucose level was systemicly monitored in 37 SGA infants for (133?115) h(range 16～524 h, median 93 h), who were non NICU hospitalized and no feeding or IV infusion when admitted at (2 6?2 4) h (range 0.25~10.0 h, median 2.0 h) of age. Results During monitoring period, there was hypoglycemia in 19 cases (51%),hyperglycemia in 2 cases (5%), and both hypo and hyperglycemia in 3 cases (8%). The median of last time abnormal glucose level appeared was 10 hr after birth, its 95% confidence interval was 5~55hr after birth. Multiple regression analysis shown delivery models bad relationship with glucose level at admition (p= 0.013). The blood glucose level was higher in vaginal delivery babies. The lower the birth weight (BW)was, the longer the duration of abnormal glucose level lasted ( O

The widespread use of antibiotics has been effectively controlled serious life-threatening infections.The trituration,exploitation and use of antibiotics has been rapidly developed and applied to many fields.Due to the extensive use of various antibiotics,the emergences of drug-resistant bacteria and the rates of bacterial resistance have increased unceasingly which has been a common focus in the world.Resistant pathogen can reduce the effectiveness of antibiotics,and which is a serious threat to human health.De-escalation therapy of antibiotics can quickly and effectively control serious infections,and avoid bacterial resistance,and induce fungal infections.The rational use of antibiotics in pediatrics is very imperative,which includes strengthening management of antibiotics,and improving awareness and vigilance of the adverse reactions of antibiotics,and consummating specification of medication.Then,realize the correct,safe,rational medication of antibiotics.

Bronchiolitis obliterans(BO) is chronic airflow obstruction syndrome characterized by small airway obstruction and airflow limitation.In children, BO is secondary to severe infection of respiratory tract, and its development is related with inflammation and immune response.At present, the diagnosis of BO mainly is depended on the clinical manifestation, lung function and examination results of high resolution computed tomography (HRCT) because of difficulty of lung biopsy.Pulmonary HRCT is a non-invasive examination, and worthy of generalization.Currently, BO has no accepted effective treatment,early diagnosis and treatment can block the progression of BO.Due to lack of realization of BO, doctors and parents fail to give enough attention, BO has a prolonged course and very poor prognosis.

Since 1950s,the idea of liver transplantation (LT) was proposed,the technique of LT had been gradually and widely applied in the field of surgery.The development of LT experienced three stages,including animal experiment,clinical probation and clinical application.It is well known that LT is the only effective therapeutic method for terminal stage of liver diseases.In liver transplantation,the ischemia-reperfusion injury is difficult to avoid,and an important factor causing poor liver function.Meanwhile,hemodynamic volatility and internal environment disorder are important prognostic factors.How to reduce ischemia-reperfusion injury of the transplanted liver and improve intraoperative hemodynamic changes in liver transplantation is a clinical research focus.Recent studies has indicated that orthotopic liver transplantation retrograde perfusion method can effectively reduce the transplanted liver ischemia-reperfusion injury and improve liver function early after transplantation,and thus significantly improve the success rate of liver transplantation and survival.

BACKGROUND:There may be tumor stem cells during metastasis and recurrence of liver cancer.The number of tumor stem cells is very few,so it is difficult to be identified.Thy-1 is a surface marking protein of oval cells.Specific marker can indirectly confirm the existence of tumor stem cells in the tumor,which is a focus in recent studies.OBJECTIVE:To study whether Thy-1 positive marked oval cells was expressed in hepatoma carcinoma cells,and investigate its screening and identification.METHODS:Flow cytometry was used to identify that Thy-1 positive expression in hepatoma carcinoma cells HepG2 and BEL-7402 and normal hepatocytes QSG-7701.Immunomagnetic bead sorting was utilized to select hepatoma carcinoma cells with Thy-1.Immunofluorescence was used to identify selected efficiency.Naked mouse inoculated with hepatoma carcinoma cells in the skin test was assigned to three groups.In the Thy-1~+ cells group,naked mice were inoculated with Thy-1~+ cells (5×10~5/mouse)underneath the skin of the back.In the HepG2 cell positive control group,naked mice were inoculated with HepG2 cells(0.5×10~7/mouse)underneath the skin of the back.In the Thy-1' cells negative control group,naked mice were inoculated with Thy-1~- cells(0.5×10~7/mouse)underneath the skin of the back.Tumorigenicity in each group was observed one month later.RESULTS AND CONCLUSION:Thy-1 expression in hepatoma carcinoma cells HepG2 and BEL7402 was significantly greater compared with normal hepatocytes QSG7701(P＜ 0.05).Positive rate of immunofluorescence staining was 85% in the Thy-1~+ cell group,1% in the HepG2 cell positive control group,0% in the Thy-1~- cell negative control group.There were nubble of five mice in HepG2 cell positive control and Thy-1~+ groups,and the volume was large.However,there was one nubble in Thy-1~- group,and the volume was significantly small(F=144.568,P＜ 0.05).Results indicated that hepatoma carcinoma cells contained Thy-1 labeled positive oval cells-like stem cells,which may be tumor stem cells in hepatoma carcinoma cells.

BACKGROUND: Rat model of orthotopic liver transplantation is a very valuable model for experimental study in liver transplantation including organ preservation, tissue ischemia-reperfusion injury, allograft rejection and immune tolerance mechanism. Stable liver transplantation animal model is the basis of the related experimental studies. However, its experimental operation is long and boring, especially performed by a single operator under direct vision. OBJECTIVE: To investigate the operation techniques to establish a stable rat model of orthotopic liver transplantation by a single operator under direct vision. METHODS: The orthotopic liver transplantation was performed using two-cuff method in 50 pairs of rats. We exposed the abdominal cavity fully, perfused the donor liver through abdominal aorta without flipping donor liver; suprahepatic inferior vena cava was in vivo cut down using one-step method, without diaphragm ring; the suprahepatic inferior vena cava was anastomosed with single-row suture, and the cuff of portal vein was installed by fixing the blood vessel forceps on rubber. Hepatic artery was not reconstructed. Fluid replacement was administered to maintain hemodynamic stability in rats after operation. RESULTS AND CONCLUSION: The donor operative time was (36.2± 2.5) minutes, donor liver trimming time was (12.2± 1.5) minutes, receptor operative time was (45.6 ± 3.5) minutes, suprahepatic inferior vena cava anastomosis time was (10.1 ± 2.1) minutes, portal vein cuff time was (1.5 ±0.9) minutes, infrahepatic inferior vena cave cuff time was (1.1 ± 0.6) minutes, anhepatic phase was (15.1 ± 2.2) minutes. The success ratio of the operation was 100% and the survival rates within 1 week and 1 month were all 100%. It is indicated that the key factors of a successful model were stable anesthesia, good donor liver perfusion, adequate exposure, skilled microsurgical technology and vascular anastomosis technique.
