The paper reviewed the history and characteristics of the public hospital reform in China. Based on the theories of corporate governance, it made analysis and comments on existing roadblocks and reform attempts in such hospitals, proposing a public hospital governance model in line with the general reforms made in China's healthcare system sector.

Objective To explore the behavioral and emotional status of the migrated children one year after they were victimized from earthquake in Wenchuan. Methods 513 victimized children migrated out of disaster area were investigated, with Achenback Child Behavior Checklist ( CBCL), the Screen for Child Anxiety Related Emotional Disorders (SCARED)and Depression Self-rating Scale for Children (DSRSC). The controls were local children ( n = 475 ) coming from the same schools. Results 487 answered files were validated. There were significant differences between the victimized and migrated children and the local children in many scores of CBCL, such as total sores( (26.73 ±6.28)Vs (20.26 ±5.76), t= 16.64, P＜0. 01 ) and withdrawal( (3.23 ±1. 68 ) Vs ( 2.02 ± 1.43 ), t = 12.91, P ＜ 0.01 ), somatization complaining( ( 2.79 ± 1. 34 ) Vs ( 1.67 ± 1.22 ), t =13.55, P ＜ 0. 01 ) and anxiety-depression scores ( ( 3.38 ± 1.79 ) Vs ( 1.95 ± 1. 21 ), t = 14.48, P ＜ 0.01 ), as well as its factors such as social problem, attentional problem, attack behavior, internalizing behavior, social communication and school scores. On the SCARED and DSRSC, the two groups were significantly different in total scores of anxiety and depression as well as in such factors as somatization, generalized anxiety, separated anxiety. Conclusion Though migrated out of the earthquake area, the victimised children still suffer obviously from behavioral problems, and anxious and depressive emotion one year after the earthquake.

Objective:To report a case of germinated teeth of the left mandibular second molar diagnosed by cone-beam CT (CBCT), and to investigate its differential diagnosis, pathogenesis, and the application value of CBCT in the diagnosis of oral and maxillofacial diseases.Methods:One case of germinated teeth of the left mandibular second molar diagnosed according to oral general examination ad CBCT findings in Zhenjiang Stomatological Hospital, China in March, 2019 was included in this study. The characteristics and differential points of supernumerary cusp, fused teeth, geminated teeth and concresence of teeth were analyzed based on literatures.Results:CBCT examination showed that the number of mandibular dentition teeth was normal, there was a large area of low-density transmission area around the root of the left mandibular second molar. Three-dimensional reconstruction results revealed that the suspected supernumerary teeth were fused with the root of the left mandibular second molar. Sagittal projections showed that the suspected supernumerary teeth were located in the buccal side of the left mandibular second molar. Axial projections showed three separate root canal orifices at the level of pulp chamber floor, and the dentin of the two was connected. The suspected supernumerary teeth had an independent pulp cavity and a clear root canal, and fused with the distal root canal of the left mandibular second molar in the middle of the root to form a root canal. A "Y"-shaped structure was displayed on the sagittal projections. CBCT showed that the left mandibular second molar was a fused root. Based on oral clinical examination, the left mandibular second molar was confirmed to be a germinated tooth.Conclusion:CBCT is one of the most important means of oral auxiliary examination. It has significant advantages in the diagnosis of tooth abnormalities. It can help clinicians to make correct diagnosis and choose the appropriate treatment scheme. It has certain clinical significance and innovation.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.
