[Summary] Glucose homeostasis is precisely regulated by glucagon of pancreaticαcell and insulin ofβcell secretion.Diabetes is a chronic disease characterized by insulin deficiency or insulin resistance (IR). Absolute or relative excess of glucagon secretion may play an important role in the development of diabetes.Previously more studies on the functions of islet βcells were reported,but less on islet αcells. There are a variety of factors involved in the regulation of glucagon secretion,such as nutrients,endocrine hormones and neurotransmitters. High fasting and postprandial blood glucose in patients with diabetes are associated with increased glucagon.Isletαcell dysfunction is closely related to the development of diabetes and the ability of responding to hypoglycemia.Further studies of α cell function and its role on the development of diabetes could provide insight into the treatment of diabetes.

OBJECTIVE:To provide references for rational application of full-automatic tablet dispensing machine in the inpa-tient pharmacy of the hospital. METHODS:According to the work flow and use of the machine,the errors and problems arising from the use thereof by our hospital were summarized and analyzed,and corresponding improvement measures and solutions were put forward. RESULTS & CONCLUSIONS:Common errors in the use of full-automatic tablet dispensing machine included errors for the machine(including in-box drug shortage warnings accounting for 58.61% and abnormal responses to the quantity of in-box drugs accounting for 36.96%),errors caused by human factors(including errors of inputting doctor’s order and errors of pharma-cist’s adding drugs)and errors of material installation and operation. The solutions put forward are as follows as adjusting the tilt angle of the outlet mouth and controlling the quantity of the drugs added to the box to reduce the errors for the machine;two phar-macists’checking doctor’s order in the hospital information system in advance to reduce the errors caused by human factors;carry-ing out operation training for operators to reduce the errors of material installation;designating special personnel to maintain the ma-chine,etc.

Objective To establish a method of neurons and glial cell culture from embryonic Gekko japonicus cerebral cortex. Methods Embryonic(E15) pallium was dissociated and digesting by trypsin.After counting,cells were seeded in culture flask.The glial cells were obtained by using differential adhesion potential combined with successive passage purified methods,and neurons were obtained by using neurobasal medium supplemented with B27.The cells were fixed and analyzed with immunohistochemic assay. Results After tetra-generation,GFAP positive cells were more than 95% in glial cells cultured condition;Neurons grew well in neurobasal medium,and NF and MAP-2 positive signals co-localized on neurons.After cultured for 10 days,the percentage of neurons was more than 95%.Conclusion The methods of isolation,culture and purification for embryonic Gekko japonicus cortical neurons and glial cells were established and it might be a valuable cell model to further investigate the central nerve system in Gekko japonicus.

In order to evaluate the overall situation of projects granted by National Natural Science Foundation of China (NSFC) in the 11th five-year plan period,the data about applications and approved NSFC projects at Cancer Institute and Hospital of Chinese Academy of Medical Sciences (CIH CAMS) were analyzed and compared with those of the 10th five-year plan period.It showed that the number of granted NSFC projects increased and the structure of program type maintained during the 11th five-year plan period.The program researchers were younger and had better education background.The quality and quantity of both the General Program projects and Young Scientists Fund projects were at high level.

Y type of fracture was produced in distal end of fresh adult human cadaver femur, and five internal fixation methods were tested for anti shear and anti torsion strength with the WD 10E machine.The results indicated that the fixation intensity of cancellous screw and bone stud was the weakest, and that of the dynamic condylar screw was the strongest.The intensity of L type plate and T type plate with the addition of cancellous or cortical compression screw were stronger than that of cancellous screw.

Objective To study the clinical and pathological characteristics, treatment results and prognosis of primary parotid non-Hodgkin's lymphoma (NHL). Methods All of our 21 patients received operative resection first and were histologically comfirmed as having T-cell (intermediate grade) and 20 B-cell lineage (2 high grade, 6 intermediate grade ,12 low grade) including 7 mucosa-associatied lymphoid tissue (MALT) phenotype. Ann Anbor stages were 16 stage Ⅰ E and 5 stage Ⅱ E lesions. All patients were treated by radiotherapy,of them 11 were also given 2～6 cycle chemotherapy. Results The overall 5-year survival rate was 77.0%. All 5 patients who died did so of distant involvement. Conclusions Our data show that MALT lymphoma can be present as a primary paroid NHL,although it is not included in the Working Formulation. Low-dose radiotherapy is of choice in the treatment. Patients with intermediate or high grade NHL should be given multi-modality therapy.

It has been reported that angiogenic growth factors may be useful in the treatment of ischemic heart disease. In our experiment a recombinant deficient adenovirus vector coding for aFGF was intramyocardially administrated into swines with chronic ischemic myocardium to investigate its effect on the improvement of myocardial function. In the present study, experimental minipigs underwent thoracotomy and placement of an Ameroid constrictor on the left circumflex branch coronary artery. Four weeks later, Ad.aFGF( n =7), Ad.Null( n =5) or PBS( n =6), was administrated directly into the myocardium at 10 sites in the circumflex branch distribution area (10 9 pfu or 100?l). Another four weeks later, cardiac function was examined by echocardiography and the results showed significant improvement of myocardial function in Ad.aFGF animals compared with Ad.Null and PBS animals. So such a strategy of gene therapy can be used in patients with ischemic heart disease.

Objective To study the regulation of iodine solution dissemination through the portal vein duo to compression of liver tissue in SD rat models.Methods SD rats were divided into three groups:liver segment blocking group,non-liver segment blocking group and placebo group.Right anterior segments of liver were blocked by blocking ribbon before the compression of liver tissue in liver segment blocking group,the liver tissue was pressed in 20 times.The procedures were all the same with blocking groups in non-liver segment blocking group except that the liver tissue is free from blocking.Placebo group only was opened and closed the abdomens.The iodine solution was injected into the liver tissue in right anterior segments and iodine ball should be confirmed under the X-ray in every experimental rats.The severity of the iodine predations in the liver was divided into four degree:Degree A indicated the iodine ball was in situ;no predations;Predations were in right anterior segments only in degree B;Degree C was found iodine spots in other liver segments except right anterior segments;Degree D indicated iodine spread to other organs.The iodine balls were pressed under the pressure between 10 and 15 mm Hg.Results Majority of iodine balls(36/45,80%)were formed successfully in liver tissues.Compression of the iodine balls in liver tissues can cause iodine predations in the vessels in liver.The severity of the dissemination was related to the pressure and the range of the pressings.The blocking of the liver segments before the operation can reduce the predations of iodine.Conclusion Pressing of the liver tissue can caused the iodine balls disseminate in vessels,cancer cells or cause thrombus disseminate in the vessels,Which can be reduced by avoiding the compression of the liver or tumom during the operation.
