Based on a review of literature and the current reform of public hospital corporate governance,such corporate governance is divided intocombined regulation and operation,anddivided regulation and operationmodels.Then the principal-agent theory was called into play to analyze the main problems and causes of the existing models.From the perspectives of government supervision and assessment,professionalization of hospital directors,market competition mechanism,thoughts were made on how to improve such corporate governance.

OBJECTIVE:To investigate the incidence,clinical features and influential factor of adverse drug events appeared in Zhuhai area.METHODS:246 cases with adverse drug events reported in our hospital from Jan.to Sep.in 2007 were analyzed statistically.RESULTS:Of the total drugs inducing adverse drug events(246 cases),anti-infectives took the lead(43.24%),which was related to its great variety,high application frequency and application range;78.05% were induced by intravenous infusion;41.12% were manifested as lesion of skin and its appendants;119(48.37%)failed to follow the direction of package inserts,of which,113 cases involved the use of anti-infectives.CONCLUSION:Medical workers should attach great importance to the acquisition of medication knowledge as well as the medication safety at each steps.

OBJECTIVE: To explore the characteristics and general pattern of adverse drug events(ADE) in Zhuhai area.METHODS: 311 ADE cases collected from Aug.2005 to Dec.2006 by Zhuhai workstation of Guangdong ARD Monitoring Center were statistically analyzed in respect of patients' age and sex,route of administration,category of drugs involved,ADR-involving organs/systems and clinical manifestations etc.RESULTS: The antiinfective drugs showed highest incidence rate of ADE,which caused ADE in 213 cases(68.49%).The most common clinical manifestations of the ADE were the damage of skin and adnexa,accounting for 51.45%(160 cases),all recovered after receiving corrsponding treatment.CONCLUSION: Allergic history of patients and their family members should be inquired in detail before the use of drugs and high alert should be given to pharmaceutical incompatibility,and the patients should be given fully attention after medication to reduce the incidence of ADE.

BACKGROUND: Studies on substitute cells of bladder smooth muscle cells are in the early period at present. Mesenchymal stem cell transplantation is an ideal method. Human amniotic mesenchymal cells can differentiate into cardiomyocytes and nerve growth factor and promote local structure repair. OBJECTIVE: To investigate the differentiation of human amniotic mesenchymal cells into smooth muscle cells following transplantation, and the effects on bladder muscle layer. DESIGN, TIME AND SETTING: The cytology in vitro study was performed at the Japan Xinzhou University from October 2006 to April 2007. MATERIALS: Human amnion was obtained from healthy full-term puerperal. A total of 18 clean female Sprague Dawley rats were randomly and equally assigned into normal bladder cell transplantation group, frostbite bladder control group, and frostbite bladder cell transplantation group. METHODS: Amnion was cut and mixed in DMEM containing trypsin. Epithelial cells were removed prior to tissues were incubated in DMEM, supplemented with collagenase and DNA enzyme. Human amniotic mesenchymal cells were harvested for use. Posterior vertex of urinary bladder was frozen using a -70 ℃ iron rod in rats of the frostbite bladder control group and frostbite bladder cell transplantation group. Hematoma appeared at the frostbite region of the bladder three days later. 100 ?L DMEM was injected into the hematoma of the rats of the frostbite bladder control group, while an equal volume of human amniotic mesenchymal cell suspension (105 cells) was injected into the hematoma of the rats of the frostbite bladder cell transplantation group. Human amniotic mesenchymal cell suspension was implanted into the normal rat bladder in the normal bladder cell transplantation group. After three weeks, the bladder tissue including partial urethra was used for bladder sample preparation. MAIN OUTCOME MEASURES: Bladder smooth muscle repair was observed using hematoxylin-eosin staining. The differentiation of human amniotic mesenchymal cells in the wall of urinary bladder was detected using fluorescence immunohistochemistry. RESULTS: Compared with the normal bladder cell transplantation group, normal wall structure of urinary bladder, few fibrosis and good proliferation of smooth muscle cells were detected in the frostbite bladder cell transplantation group, while the wall of urinary bladder was slowly repaired, and disorder muscle structure, fibrosis, scar-like shape, and inflammatory cells were found in the frostbite bladder control group. Three weeks later, human amniotic mesenchymal cells were not seen in the normal bladder tissue. A large number of human amniotic mesenchymal cells was lived and some of them had differentiated into the smooth muscle cells in the frostbite bladder cell transplantation group. CONCLUSION: Human amniotic mesenchymal cells had the potential to differentiate into bladder smooth muscle cells and promoted self-repair of the wall of urinary bladder.

Objective To investigate the heritability of Graves′ disease (GD) and to discuss its clinical significance. Methods The heritability of GD was calculated using Falconer′s formula and by investigating the GD numbers of 1968 first relatives of 526 established GD patients. Results The heritability of GD was 45%, appearantlymuchlowerthanthoseofprevious reports in China. Conclusion The onset of GD is affected by both inheritant and environmental factors, the latter seems to be predominant over the former.

Objective To summarize the diagnostic and therapeutic experiences of 18 patients with chronic expanding intracerebral hematoma.Methods Clinical data of 18 patients with chronic expanding intracerebral hematoma was analyzed retrospectively.Results Most of the lesions were misdiagnosed preoperatively as cerebral neoplasms.Among 18 cases, 15 cases were cured, 2 cases had severe disability, and one case died after operation.Conclusions Chronic expanding intracerebral hematoma must be considered when encapsulated mass lesion is present in the brain. The ultimate diagnosis is confirmed at surgery and by histological analysis.

Objective To investigate the new therapy for primary intraventricular hemorrhage (PIH).Methods 31 cases of PIH were treated by rigid neuroendoscopy.The cases were composed of 16 cases of single intraventricular hemorrhage,14 cases of double intraventricular hemorrhage and 1 case the third-fourth intraventricular hemorrhage.24 cases were accompanied with acute obstructive hydrocephalus.Results Duration of operation lasted from 30 minutes to 60 minutes, with an average time of 43.4 minutes.More than 90 percent of hemorrhage in 24 cases with single or double intraventricular hemorrhage were evacuated. 50 percent to 90 percent of hemorrhage were evacuated in other 7 cases. Neurological status was obviously improved and improved in 25 cases, no change in 4 cases and dead in 2 cases.Only one patient developed hydrocephalus.Conclusion Neuroendoscopic neurosurgy for PIH was characterized by visualized manipulation, shorten operative time,minimal invasion, effective hemorrhage evacuation and excellent post-operative outcomes.

With growing dependence on picture archiving and communication systems(PACS) for viewing images,a quality assurance program to the condition of workstation displays and image quality guidelines for better cost-efficacy and diagnostic accuracy has become increasingly important.This article analyses and synthesizes the quality control of the PACS phantom workstation mainly from such aspects as the monitor resolution and brightness,the environment degree of illumination,statistics assessment method(ROC curve) and so on.

Objective To investigate the role of biopsy kidney allograft in the early diagnosis and differential diagnosis of acute and chronic rejection and other diseases involving renal allograft,and to determine the optimal time for early biopsy in chronic allograft rejection.Methods Non-random biopsy of renal allograft was performed in 44 kidney transplant recipients with the clinical manifestation of diagnosis-unconfirmed allograft diseases,in the presence increased in serum creatinine,microalbuminuria or/and proteinuria,glomerular hematuria and so on.Another 6 kidney transplant recipients received routine allograft biopsy 1 month after operation.Pathological evaluation was performed in all sections according to Banff 97 classification and based on clinical data.Results Chronic allograft rejection was discovered in the renal allograft specimens of 31.3%,76.5% and 88.2% recipients,respectively,in the 1st year,the 2nd to 3rd year and over 3 years after operation,and most of them showed no obvious clinical manifestation.A part of recipients with clinical diagnosis of acute rejection also showed pathological manifestations of chronic rejection and/or glomerulonephritis and chronic cyclosporine nephropathy.A part of recipients with clinical diagnosis of chronic rejection showed pathological manifestations of acute rejection and/or glomerulonephritis and chronic cyclosporine nephropathy.Pathological features of acute or chronic rejection,glomerulonephritis and chronic cyclosporine nephropathy were observed respectively in recipients with disorders of kidney allograft with unknown diagnosis.No obvious clinical symptoms were observed in nearly half of the patients with pathological diagnosis of glomerulonephritis.Good therapeutic effect was obtained in these recipients who were correctly treated on the basis of definite pathological diagnosis.Conclusions It is indicated that optimal time for early diagnosis in chronic renal allograft rejection might be the 2nd and 3rd year after transplantation,and routine biopsy should be performed in this period.It is suggested that biopsy of renal allograft is of importance value for rectification of clinical diagnosis and for recipients with clinically undefined renal allograft diseases.It is also indicated that there might be coexistence of acute,chronic rejection and/or glomerulonephritis and chronic cyclosporine nephropathy.
