Objective To probe into the social support, coping styles, and mental health status of medical staff in a tertiary hospital in Beijing, for identifying potential mental problems. Methods Such means as the Social Support Rating Sheet (SSRS), Simple Coping Style Questionnaire (SCSQ), Symptom Checklist (SCL-90), and demographic characteristics questionnaire were called into play, to study 2460 medical staff in five tertiary hospitals in Beijing. Results Differences were identified among medical staff of different demographic characteristics, in terms of positive coping style and support dimensions. Analysis of the survey data indicates that the total SCL scores, total symptom problem index, positive symptom pain level, total average score of the factors, are positively related to passive coping style, as P<0. 01; and are negatively related to subjective/objective support, support utilization, and total support scores, as P<0. 01. Conclusions Hospital administration is expected to implement focused intervention to such medical staff as those under 40 years old, women, widows or divorcees, those with education lower than university degree, those with junior academic title or lower, those without titles, those in emergency departments and emergency intensive care units, doctors and nurses, frequent night-shift workers, those of excessively low self evaluation, and medical staff with chronic diseases. The purpose of this practice is to alleviate their mental stress.

OBJECTIVETo explore the effect of combined therapy of shenmai and compound danshen injection (SM-DS) on myocardial reperfusion injury after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).

METHODSThirty-eight AMI patients who received PCI were randomly divided into two groups, the 19 patients in the treated group were treated with SM-DS before and after PCI. Serum levels of malondialdehyde (MDA), superoxide dismutase (SOD), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) in patients' venous blood were measured at different time-points, and the integrated left ventricular ejection isometric index (Tei) was determined by echocardiogram.

RESULTSAs compared with before operation in the treated group, MDA was higher and SOD was lower at 2 hrs, 24 hrs after operation (P < 0.05); IL-6 and TNF-alpha were significantly lower at 24 hrs, 48 hrs and 1 week (P < 0.05, P < 0.01) and the Tei began to be improved at 24 hrs (P < 0.05) and significantly improved at 1 week after operation (P < 0.01). While in the control group, MDA was higher and SOD was obviously lower at 2 hrs and 24 hrs (P < 0.01); lowering of IL-6 and TNF-alpha appeared at 1 week (P < 0.05) and improving of Tei index revealed 1 week after operation respectively (P < 0.05). Comparison between the two groups showed significant difference in levels of MDA and SOD at 2 hrs and 24 hrs (P < 0.01); significant difference in levels of IL-6, TNF-alpha at 24 hrs, 48 hrs and 1 week; and in Tei index at 24 hrs and 1 week after operation (P <0.05).

CONCLUSIONSM-DS could reduce the myocardial reperfusion injury in patients with AMI after PCI.

Objective: To study a new method of alveolar cleft bone grafting. Methods: Group A: 62 cases (74 sides) alveolar cleft patients were transplanted with self-ilium spongy bone. Group B: 26 cases (30 sides) alveolar process patients used autologous ilium combined with DDM. Anterior occlusal radiographs and panoramic oral radiogram were taken before and after the operation to observe if there was new bone formation in the bone grafting area. According to Bergland grade criterion, analyzed the X-ray results after 3 months of the operation. Results: Group A: 17cases(17 sides) in class 1 group(23%), 17 cases(20 sides) in class 2 group(27%), 13 cases(14 sides) in class 3 group (19%), 15 case(23 sides) in class 4 group(31%). The overall survival rate of ABGR was 68.9%, and the clinical success rate was 50 %;Group B:16 cases(16 sides) in class 1 group(53.3%), 7 cases(8 sides) in class 2 group(26.7%), 2 cases(4 sides) in class 3 group (13.3%), 1 case(2 sides) in class 4 group(6.7%). The overall survival rate of ABGR was 93.3%, and the clinical success rate was 80%. Conclusion: Ilium spongy bone combined with DDM is good for alveolar process cleft bone grafting. It is better to use decalcified dentinal matrix of human than autologous ilium spongy bone.

The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To study the relationship between coronary arteriographic and fluorescence fundus angiographic characteristics in type 2 diabetic patients with coronary heart disease.Methods The study was carried out by the analysis of the data from coronary arteriography and fluorescence fundus angiography in 203 type 2 diabetic patients with coronary heart disease in different groups divided according to age or total cholesterol level. Logisitic regression analysis was applied to explore various risk factors to angiographic characteristics.Results With advancing age,there were more involvement of 3 coronary vessels or the left main branch along with stageⅢretinopathy,but less single vessel diseases in the coronary arteries and less stageⅠretinopathy.The difference in coronary angiographic and fluorescence fundus angiographic characteristics between groups with different total cholesterol levels was not significant.Logistic regression analysis suggested that coronary artery diaease was related to age,sex and blood glucose and triglyceride levels while diabetic retinopathy was related to blood glucose level and age.Conclusion There is great difference in coronary arteriography and fluorescence fundus angiography among different age groups.Aging may aggravate the lesions both in the coronary arteries and fundal vessels in type 2 diabetic patients with coronary heart diseease.

Objective To report an epidemiological investigation on identification of the first case of coronavirus disease 2019(COVID-19) in Jinghu District of Wuhu City. Methods A field epidemiologic survey was conducted on the case.Throat swab sample was tested using real-time reverse transcription polymerase chain reaction (RT-PCR) assay to detect the nucleic acid of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).The close contacts of the case were tracked and appropriate prevention and control measures were implemented. Results The case had lived in Xi′an usually and arrived in Wuhu from Xi′an on January 22 of 2020.On January 23, the patient developed respiratory symptoms but the diagnosis of COVID-19 was excluded after two negative SARS-CoV-2 nucleic acid tests.On January 26, the patient was admitted to hospital again due to fever, chest tightness and other symptoms.On January 27, the patient tested positive for SARS-CoV-2 nucleic acid and was confirmed with COVID-19 after a review by the Anhui Provincial Center for Disease Control and Prevention.The case had no history of travel or residence in Wuhan, and no history of contact with wildlife or markets, however, had close contact with a confirmed COVID-19 patient before returning to Wuhu. Conclusion Based on the epidemiological history, clinical symptoms and the results of the SARS-CoV-2 nucleic acid test, the patient is determined as the first reported case of COVID-19 in Jinghu District of Wuhu City.

OBJECTIVETo establish a mouse model of biliary obstruction.

METHODSSixty-four Balb/c mice were divided into experimental group and control group. Obstructive jaundice was induced in the mice in the experimental group by common bile duct ligation. The level of the common bile duct diameter, WBC, LYM MID, LYM%, MID% and ALT, AST, TBIL, DBIL, IBIL, ALP and CHOL were measured 12 h and 1, 2 ,3, 4, 5, and 7 days after the ligation. The morphological changes in the liver were also observed.

RESULTSThe level of common bile duct diameter, WBC, LYM, MID, LYM%, MID% and ALT, AST, TBIL, DBIL, ALP and CHOL all underwent changes with time following certain patterns.

CONCLUSIONThe jaundice manifestation of this model is similar to that of patients with biliary obstruction, and this model may provide a reliable model for studying the mechanism of obstructive jaundice.

OBJECTIVETo investigate the expression profiles of serum Golgi protein-73 (GP73) in liver cirrhosis and primary hepatic carcinoma (PHC) and determine its clinical value for differential diagnosis.

METHODSSerum protein expressions of GP73 and alpha-fetoprotein (AFP) were detected by enzyme-linked immunosorbent assay and chemiluminescence assay, respectively, in patients with PHC (n=80), liver cirrhosis (n=65), and healthy controls (n=50). Inter-group changes were assessed by Kruskal-Wallis test, and significance of these differences was assessed by Mann-Whitney test. A receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency and determine the cut-off values for GP73 and AFP. Sensitivity and specificity were compared by the Chi-squared test. Correlation between serum GP73 expression and clinical parameters was determined by Spearman's rank correlation analysis.

RESULTSThe PHC group showed significantly higher serum GP73 (282.0 mug/L) than the liver cirrhosis group (211.8 mug/L) and control group (58.3 mug/L) (H = 93.30, P less than 0.01). For differential diagnosis of PHC and liver cirrhosis, the cut-off value was 318.1 mug/L for GP73 and 13.4 mug/L for AFP. Sensitivity of GP73 was lower than AFP (45% (36/80) vs. 65% (52/80); X2 = 8.02, P less than 0.05). Specificity of GP73 was lower than AFP but no significance was found (83.1% (54/65) vs. 87.7% (57/65); X2=0.27, P more than 0.05). The areas under the ROC curves were not significantly different between GP73 and AFP (0.65 (95% confidence interval (CI): 0.54~0.72) vs. 0.75 (95% CI: 0.67~0.83); Z = 1.88, P more than 0.05). The area under the ROC curves increased but not significantly (0.80 (95% CI: 0.73~0.88) vs. 0.75 (95% CI: 0.67~0.83); Z=2.61, P more than 0.05). Serum GP73 was correlated with liver cirrhosis (r=0.27), vascular invasion (r=0.29), and TNM staging (r=0.27) (all P less than 0.05), but not with sex (r=0.13), age (r=0.10), enhanced AFP (> 13.4 mug/L; r=0.03), tumor size (r=0.18), or distant metastasis (r=0.04), all P less than 0.05.

CONCLUSIONSerum GP73 and AFP have comparable diagnostic efficiency, but the sensitivity of AFP is superior for differential diagnosis of liver cirrhosis and primary hepatic carcinoma. Elevated serum GP73 may be correlated with liver tumor load and aggressiveness.
