How to handle the relationship between doctors and patients is currently a hot spot of society. The author first expounds the fundamental propositions in the theories of the science of value. Then, using the theories of the science of value, he first describes the relationship between the object and subject of value, viz. who comes first, the patients or the staff, arguing that in the mind of the hospital director there should always be an unbiased balance of value benefiting both sides. Then he describes the realistic form in which value exists, viz. which is more important, the value of utility or the value of effectiveness, arguing that the hospital director should lay equal emphasis on the staffs value of utility and the patients value of utility, thus satisfying both sides. Thirdly, the author describes value accounting and the cost of value, viz. the dual unity of the values of effects and effectiveness, arguing that creating value while paying cost indicates the dual nature of the practice of hospital administration. Hence the need to lower cost as much as possible and create greater value.

Objective To investigate the effects of hyperoxic-hyperosmotic sodium chloride solution(HHSCS) on arterial blood gas and blood lactate in rabbits with hemorrhagic shock, and evaluate the HHSCS effects on hemorrhagic shock resuscitation.Methods Hemorrhagic shock models were induced in 30 male rabbits.The median arterial pressure(MAP) was declined to 40mmHg within 10 minutes,then maintained for 60(minutes).The animals were then randomly divided into 3 groups:normal saline hyperoxic solution(NSO)group,hyperosmotic sodium chloride solution(HS)group and HHSCS group.Sixty minutes later,NSO,HS or HHSCS 6ml/kg was infused intravenously in 5 minutes.Heart rate(HR) 、respiratory rate(RR)、 MAP and urine drops(UD) before shock and after fluid infusion were recorded;blood lactate(BL) and blood gas were measured before shock,60min after shock,and 30min,60min,120min postinfusion.Finally,the(rabbits) were killed by bleeding,the lungs were observed in autopsy,and the lung coefficient was measured.Results HS and HHSCS more effectively raised MAP,enhanced heart function,and increased UD than NSO.HHSCS group significantly reduced BL.At 60,120min after infusion,SaO_2 in HHSCS group was(significantly) higher than that in HS group and NSO group(P

Objective　To evaluate the result of unilateral ex ploration for the treatment of hyperparathyroidism caused by parathyroid adeno ma.　Methods　Clinical data of 20 case s from 1986 to 1999 were retrospectively analysed. Preoperative imaging examinat ion was suggestive of unilateral lesion and unilateral exploration was performed accordingly.Results were compared with that of bilateral exploration.　Results　In 19 out of 20 cases the result of u nilateral exploration was satisfactory making bilateral approach unnecessary exc ept for one whose symptom was later proved to be caused by bilateral lesions.Conclusions　The authors came to the c onclusi on that solitary adenoma is the most common cause of hyperparathyroidism in Chin ese patients,hence unilateral exploration is of advantages.

Objective To investigate the therapeutic effects of glucocorticoids(GC)on brain damage in rats with severe acute pancreatitis(SAP).Methods Thirty two rats were randomized into the normal control group(Group A),acute pancreatitis group(Group B),common carotid therapeutic group(Group C)and lateral ventricle therapeutic group(Group D).The rats in group C and D were respectively given methylprednisolone through common carotid artery and lateral ventricle. All rats were killed 24r h later to determine the weight of water content in the brain.The pancreatic and brain tissues were stained with HE.Meanwhile,the brain samples were immunohistochemically stained and the medulla sheath specially stained to determine TNF-α and IL-2.Histopathological scoring of pancreas and counting of leukocytes in the brain were conducted.Results Group A had no obvious pathologic changes.Group C and D had fewer TNF-α positive cells in the brain than Group B.IL-2 was negative in each group.Brain edema,leukocyte number and demylination of myelinated nerves in Group C and D were significantly different from those in Group B(P＜0.05).Conclusion Demylination of myelinated nerves is the characteristic change in SAP.Brain edema,leukocyte infiltration and nerve cell degeneration would happen as well.TNF-α plays an important role in the development of SAP.GC has effects on prevention and therapy of brain damage in rats with SAP.

Objective To investigate the different clinical behavior and the diagnosis and trearment of primary hyperparathyroidism(PHPT). Methods Clinical data of 53 patients with PHPT treated in Beijing Jishuitan Hospital from May 1977 to April 2004 were collected and analyzed. Results 53 patients with PHPT were confirmed by operation and pathology. The majority of the patients were aged 20~50 years. There were more female than male patients. There were various clinical manifestations, and the duration of illness was (protracted). Many cases were misdiagnosed. There were bone pathologic changes of varying extent in all (patients), stones in urinary system plus bone pathology in 11 cases, serum level of calcium was raised in 51 patients(96.2%) and (parathyroid) hormone (PTH) was elevated in all examined 48 cases. Ultrasound, MIBI and CT were done before operation after 1991, and accurate preoperative localization diagnosis was (obtained). Minimally invasive (parathyroidectomy) (MIP) was successfully completed in 39 of 45 cases, and the primary operation cure rate was 97.4%. At postoperative follow-up of 10 months to 10 years, with the (exception) of 15 cases of severe bone deformity that had no obvious improvement, the other symptoms and signs were all relieved to varying (extents), the laboratory markers returned to normal, and there was no permanent hypoparathyroidism or (recurrent) nerve injury or other complications.Conclusions Early diagnosis of PHPT and effective early (treatment) by surgical removal of the pathologic lesion can alleviate the occurrence of severe bone changes and deformity. The preoperative combined use of imaging localization technique and overall assessment can improve the accuracy of diagnostic localization of the lesion.

ObjectiveTo investigate the effect of nitric oxide(NO) in preventing postoperative adhesion formation in rats .MethodsForty rats were randomly assigned to 2 different treatment groups.All animal models of postoperative adhesion formation were made in a standard manner. 0.9% NaCl and L-arginine were administered into intraperitoneal cavity before closure and during 3 consecutive days after surgery. On the 3 rd postoperative day,blood was collected to evaluate NO levels and the inserted abdominal walls were removed to assess pathology in some rats.On the 14 th postoperative day,the remaining rats were sacrificed by ether overdose before relaparotomy,and the extent of adhesion formation were assessed.ResultsMore severe adhesions developed in 0.9% NaCl control group(mean score of adhesions 3.7?0.7) than L-arginine group(mean score of adhesions 0.9?1.1)( P

Objective To investigate the polymorphism of the vitamin D receptor(VDR)gene in relation to primary hyperparathyroidism(PHPT). Method Polymerase chain reaction and restriction analysis were used to determine VDR genotypes in 30 patients with PHPT and in normal subjects.ResultsThe frequency distribution of VDR genotypes in PHPT patients was 0 in BB,1(3.3%) in Bb, 29(96.7%) in bb; and in normal persons was 2(3.3%) in BB, 11(18.4%) in Bb, and 47(78.3%) in bb. There was a significant difference between PHPT patients and normal persons in distribution of BB, Bb, bb genotypes (P≤0.05).ConclusionsThere is some distribution alterations of VDR gene polymorphism in PHPT patients.

ObjectiveTo evaluate nonoperative management of adult blunt hepatic injury. MethodThe outcome of 132 cases with adult blunt hepatic trauma admitted in this hospital between Oct 1982 and Oct 2002 was analyzed. Thirty-four cases (25.8%) were treated by nonoperative management. Before 1995, only a portion of patients underwent CT scan and after 1995, diagnosis of liver injury was established by CT scan in all cases. ResultThe nonoperative management rate before 1995 was 16.7% (14/84) and after 1995, it was 41.7% (20/48)(P0.05). ConclusionWith the progress of image monitoring and life support system, some patients of blunt hepatic injury could be managed by conservation therapy.
