Based on the needs of healthcare system reform, Australia has implemented activity based funding(ABF) payment mode nationwide, and established the Independent Hospital Pricing Authority as the specific implementation agency in 2011. The main responsibilities and functions of the ABF payment mode covers pricing of medical services, classification of healthcare services, collection of clinical data and cost accounting of healthcare services. ABF payment mode presents outstanding advantages in promoting the capacity of healthcare service, maintaining fairness of healthcare service supplies and carrying out cooperation across different institutions. These efforts provide important references for China in its top-level design of payment method, pilot project of classification system, medical service items and price dynamic adjustment, informationization and information standardization construction among public hospitals.

This study investigated the mental health status of medical students in China, and analyzed the influencing factors in order to provide evidence for mental health education for medical students. A stratified cluster sampling method was used to recruit medical students from Huazhong University of Science and Technology, China. The questionnaire survey on general information and Symptom Checklist 90 (SCL-90) were used for investigation and analysis. The results showed among the 1137 valid questionnaires, 278 (24.45%) participants had SCL-90 score ≥ 160. The top three mental problems of medical students were obsessive-compulsive disorder, interpersonal sensitivity and depression in terms of the factor score ≥ 2.5 and the number of participants who reflected on the diseases. The third-year medical students had the worst mental health status, and fifth-year medical students had the best mental health status. Students from rural area had more psychological problems than those from urban area; furthermore, students with high professional satisfaction, those who were the single child of the family, non-poor students, and those whose parents had high education level had better mental health status. It was concluded that the mental health of medical students is not optimistic in China. Medical students have some mental health problems of different degrees. Factors that influence the mental health of medical students include academic pressure, professional satisfaction level and family environment.

OBJECTIVETo investigate the correlation between left atrial size and left ventricular filling pressure (LVFP) and the value of left atrial size assessment on detecting diastolic dysfunction in hypertensive patients with preserved LVEF by echocardiography.
METHODSEchocardiography was performed in 346 hypertensive patients with preserved LVEF(≥ 50%), left atrial size including left atrial diameter (LAD) and left atrial area (LAA) was measured and indexed to body surface area (LADI, LAAI). The ratio of early diastolic transmitral velocity to early diastolic mitral annular velocity (E/Em) was determined and LVFP was calculated with the formula: LVFP = 1.24×E/Em + 1.9. Patients were divided into diastolic dysfunction group [DD group, LVFP > 15 mm Hg (1 mm Hg = 0.133 kPa), n = 81] and normal diastolic function group (NDF group, LVFP ≤ 15 mm Hg, n = 265).
RESULTSAs compared to patients in NDF group, the patients in DD group had larger LA [LADI: (21.4 ± 2.6) mm/m(2) vs. (19.6 ± 2.4) mm/m(2); LAAI: (12.1 ± 2.6) cm(2)/m(2) vs. (10.4 ± 1.7)cm(2)/m(2); all P < 0.01]. LA size parameters were positively correlated with LVFP (r = 0.211-0.450, all P < 0.01), LAAI was best correlated with LVFP (r = 0.450, P < 0.01). ROC analysis showed that LAAI ≥ 11.4 cm(2)/m(2) diagnosed DD with a sensitivity of 63%, specificity of 74% and accuracy of 72%.
CONCLUSIONLeft atrium dilation correlates positively with LVFP in hypertensive patients with preserved LVEF. The LAAI is a more accurate parameter for identifying patients with diastolic dysfunction in this cohort.

OBJECTIVETo study the effect of insulin, cyclic adenosine monophosphate (cAMP), and dexamethasone (DEX) on 550 bp (-600 -/+ 69) fragment of phosphoenolpyruvate carboxykinase (PEPCK) gene promoter by reporter gene.
METHODSThe recombinant pGL2-PEPCK-Luc and the control plasmid pSV-beta-Galactosidase were co-transfected to rat hepatoma cell line (CBRH7919) by lipofectin. By measuring luciferase activity, we evaluated in vitro regulation of PEPCK gene promoter on reporter gene transcription.
RESULTScAMP and DEX stimulated PEPCK promoter obviously; meanwhile, they also had accumulative effects. At different physiological concentrations, insulin had a suppressive effect on PEPCK promoter, which was dose-independent.
CONCLUSIONThere is a perfect feedback mechanism for PEPCK promoter in hepatoma cell. 550 bp (-600 -/+ 69) fragment of PEPCK may be a candidate gene in the gene therapy of diabetes.

OBJECTIVETo evaluate the value of magnetic resonance imaging (MRI) in displaying the parotid gland segments of the facial nerve.
METHODSSixteen volunteers (9 males and 7 females) and 132 surgically confirmed patients with parotid tumors locating in the deep or shallow lobe of the parotid gland (including 89 with benign and 43 with malignant tumors) underwent MRI using T1WI and T2WI. The transverse images were obtained with the plane tilted 35 degrees to the foot, and the coronal images were acquired using conventional scanning.
RESULTSOn transverse T1WI, the parotid gland segments of the facial nerve displayed low signal with arc-shaped curve in the cross-section, showing a symmetrical dot-like low signal in the coronal plane. The facial nerve in 63% of the patients with parotid tumors in the cross-section could be displayed, but in the coronal plane the proportion reached 83%. MRI could accurately reveal the position of the parotid tumors in the deep or shallow lobe of the parotid gland.
CONCLUSIONMRI can show the major portion of the parotid gland segments of the facial nerve and has important value in locating the parotid tumors and displaying the relationship between the tumor and facial nerve.

OBJECTIVESTo analyze the clinical characteristics of the atlantoaxial dislocation (AAD) in craniovertebral junction (CVJ) abnormalities and to study the setup of its surgery strategy.
METHODSFrom April 2009 to November 2011, 56 patients of AAD and CVJ abnormalities including 22 male and 34 female patients who had received surgery were analyzed. There were 2 cases of reducible AAD and 54 cases of irreducible AAD. The age of the patients ranged from 9 to 56 years (mean 34 years). Among them, 14 cases achieved reduction/partial reduction via direct posterior fixation, 41 cases had transoral anterior deconpression and occipito-cervical/C₁-C₂ fusion and 1 case had the posterior odontoidectomy and spinal fusion.
RESULTSFifty-three cases had a follow-up between 6 months and 36 months (mean 20 months) and 3 cases lost follow-up (had improvement at discharge). Seven cases had complications as follows: 1 case had irreversible spinal cord injury and muscle weakness of extremities, 2 cases had cerebrospinal leak, 2 cases had pulmonary infection, 1 case had local granuloma hyperplasia and 1 case had delayed healing of the incision. The later 6 cases all got recovery after reasonable treatments. The grades of Nurick at last follow-up were as follows: 6 cases (11.3%) improved by 3 grades, 30 cases (56.6%) improved by 2 grades, 13 cases (24.5%) improved by 1 grade, 3 cases (5.7%) without change, 1 case (1.9%) get worse.
CONCLUSIONSReducible AAD could achieve direct reduction and fixation via posterior pathways. Irreducible AAD needs individualized treatment. To choose the direct reduction and fixation or transoral odontoidectomy and posterior fixation and fusion should consider the pathogenetic condition, the image data and personal clinical experience.

OBJECTIVETo explore the effect of rosiglitazone on the activity of signal transducer and activator of transcription 1 in rats with severe acute pancreatitis.
METHODSFifty-four male Wistar rats were randomly allocated into three groups (n = 18). SO group: sham-operated animals served as control, operation was executed and sodium chloride but not sodium taurocholate was injected. SAP group: SAP was induced by the retrograde injection of 5% sodium taurocholate into the biliopancreatic duct. ROSI group: same as SAP group, but rosiglitazone (6 mg/kg) was administered intravenously 30 min before operation. Rats in each group were sacrificed at 3,6 and 12 h after operation. The levels of serum amylase and histologic scores of pancreatic tissue were measured. The expression of TNF-alpha mRNA in pancreatic tissue were determined by reverse transcription-polymerase chain reaction (RT-PCR). The expression of phosphorylated STAT1 in pancreatic tissue was assayed by immunohistochemistry.
RESULTSCompared to SO group, the levels of serum amylase and phosphorylated STAT1, TNF-alpha mRNA and histologic scores of pancreatic tissue were significantly elevated at the same time points after SAP (P < 0.01). The levels of these detection in ROSI group were lower than those of the SAP group at the same time points (P < 0.05), but higher than SO group (P < 0.05).
CONCLUSIONSSTAT1 was activated in severe acute pancreatitis. Rosiglitazone has a protective effects in rats with severe acute pancreatitis. The mechanism of its protective effects maybe that it inhibits the activation of JAK/STAT pathway, which can down-regulate the expression of TNF-alpha mRNA and block the the inflammatory cascade partially.
