Coronavirus disease 2019 (COVID-19) is a new infectious disease rapidly spreading around the world, raising global public health concerns. Radiological examinations play a crucial role in the early diagnosis and follow-up of COVID-19. Cross infection among patients and radiographers can occur in radiology departments due to the close and frequent contact of radiographers with confirmed or potentially infected patients in a relatively confined room during radiological workflow. This article outlines our experience in the emergency management procedure and infection control of the radiology department during the COVID-19 outbreak.

OBJECTIVE:
To explore risk factors of the periprosthetic fracture after hip arthroplasty.
METHODS:
Potential studies were searched in databases including Pubmed, Embase, Cochrane Library, CNKI as well as Wanfang Database up to November 2018 and references in related literatures. The methodological quality of literature was estimated by Newcastle-Ottawa Scale. Raw data were merged and tested mainly by Revmain 5.3.
RESULTS:
Seventeen studies in total were appropriate with 90 632 patients. The results revealed that it increased the risk of periprosthetic fracture after hip arthroplasty, including female (=1.62, 95%CI:1.44 to 1.82, <0.01), revision(=3.78, 95%CI:1.88 to 7.58, <0.01), preoperative diagnosis of rheumatoid arthritis(=1.60, 95%CI:1.07 to 2.37, =0.02). Conversely, patients involved with cemented prosthesis fixation(=0.43, 95%CI:0.27 to 0.68, <0.01) were less likely to suffer periprosthetic fracture after hip arthroplasty. Other factors were not significantly relevant to periprosthetic fracture after hip arthroplasty, including the age, preoperative diagnosis(femoral head necrosis, osteoarthritis, developmental dysplasia of the hip, femoral fracture, concomitant heart diseases) and American Society of Anesthesiologists >=3.
CONCLUSIONS
Orthopedics doctors should constantly be cantious about the risk factors including female, revision and diagnosis of rheumatoid arthritis. They are supposed to prevent the periprosthetic fracture by gentle operation during hip arthroplasty and monitoring the functional exercise after operations when the above risk factors occur.

Obstructive nephropathy ultimately leads to end-stage renal failure. Renovascular lesions are involved in various nephropathies, and most renal diseases have an ischemic component that underlies the resulting renal fibrosis. The aim of this study was to investigate whether morphological changes occur in the renal vasculature in hydronephrosis and the possible mechanisms involved. A model of complete unilateral ureteral obstruction (CUUO) was used. Experimental animals were divided into five groups: a normal control group (N) and groups of animals at 1st week (O1), 2nd week (O2), 4th week (O4) and 8th week (O8) after CUUO. Blood pressure was measured, renal arterial trees and glomeruli were assessed quantitatively, and renovascular three-dimensional reconstruction was performed on all groups. Glomerular ultrastructural changes were examined by transmission electron microscopy. The results showed that the systolic blood pressure was significantly increased in the obstructed groups (O1, O2, O4 and O8). Three-dimensional reconstruction showed sparse arterial trees in the O8 group, and a tortuous and sometimes ruptured glomerular basement membrane was found in the O4 and O8 groups. Furthermore, epithelial media thickness and media/lumen ratio were increased, lumen diameters were decreased, and the cross-sectional area of the media was unaltered in the segmental renal artery, interlobar artery and afferent arterioles, respectively. In conclusion, renal arterial trees and glomeruli were dramatically altered following CUUO and the changes may be partially ascribed to vascular remodeling. Elucidation of the molecular mechanisms of renovascular morphological alterations will enable the development of potential therapeutic approaches for hydronephrosis.

The aim of this study was to investigate the clinical characteristics and prognosis of acute erythroleukemia (AEL, AML-M6). The clinical features and results of morphologic, immunophenotypic, cytogenetic and molecular biologic detections were retrospectively analyzed in 13 cases of AEL from 305 acute leukemia patients hospitalized between October 2007 and October 2012. The results showed that the expression of erythroid and non-erythroid cells increased at the same time. The myeloid antigens mainly expressed CD13/CD33/CD117/CD34, while the erythroid antigens expressed Gly and CD71. The karyotypic detection indicated that there were 1 case with normal karyotype, 3 cases with simple karyotypic abnormality and 2 cases with complex karyotypic abnormality, the other cases were not detected. The molecular biological detection found that the poor prognosis gene existed in 5 cases [38.5% (5/13)], including 3 cases with MLL-MLL fusion gene, 1 case with MLL mutation, and 1 cases with NRAS gene mutation, the abnormal genes were not detected in remainder 8 cases. After chemotherapy with decitabine, the complete remission (CR) rate achieved 53.5% (7/13), partial remission (DR) rate achieved 15.4% (2/13). Finally, 8 patients received allo-HSCT, the median overall survival (OS) was 20.7 months, 3 year survival rate was 79%, 3 year disease-free survival rate was 78%. It is concluded that the acute erythroleukemia is a rare subtype of AML, which is transformed from MDS and has harmful genes and poor prognosis. Allo-HSCT and treatment with decitabine may enhance the survival rate of AEL.

OBJECTIVETo evaluate the intervention effect of health education on hypertension knowledge in mid-western rural area of Shandong province.
METHODSA project was launched on chronic disease control in mid-western rural area of Shandong province from 2007 to 2010. The baseline survey was performed using multi-stage random sampling method in 8 counties of mid-western rural area of Shandong province in April, 2007. A total of 20 087 participants aged 25 and above were recruited in the survey to study the relationship between awareness of hypertension and diet, smoking, obesity. Health education focusing on balance diet, physical activity promotion and tobacco control was performed among intervention population. The final evaluation survey using same questionnaire was performed in 2010, classified in intervention (4071 participants) and control (2145 participants) group. Control group was selected from non-intervention town in same county. Intervention and control group shared the same baseline data in 2007 for evaluation. By comparing the changes of hypertension knowledge before and after intervention, the intervention effect was evaluated.
RESULTSAwareness of the relationship between hypertension and diet rose from 34.0% (6830/20 087) at baseline in 2007 to 69.3% (2821/4071) (χ(2) = 1757.30, P < 0.01) of intervention group and 44.8% (961/2145) (χ(2) = 99.30, P < 0.01) of control group in 2010. Awareness of hypertension associated to smoking rose from 25.6% (5142/20 087) at baseline in 2007 to 55.2% (2247/4071) (χ(2) = 1396.59, P < 0.01) in intervention group, 30.9% (662/2145) (χ(2) = 27.83, P < 0.01) in control group in 2010. Awareness of hypertension related to obesity rose from 37.2% (7472/20 087) of the baseline in 2007 to 68.3% (2780/4071) (χ(2) = 1339.27, P < 0.01) in intervention group, 45.1% (967/2145) (χ(2) = 51.14, P < 0.01) in control group in 2010.
CONCLUSIONCommunity comprehensive intervention showed significant effects on hypertension related knowledge improvement in mid-western rural area of Shandong province.

OBJECTIVETo explore the effects of sperm chromatin structure abnormalities on the outcome of in vitro fertilization and embryo transfer (IVF-ET).
METHODSSperm DNA fragmentation and chromatin packaging defects were assessed in 136 couples undergoing IVF-ET because of infertility. The relationship between sperm DNA fragmentation, chromatin packaging defects and fertilization rate and clinical pregnancy was evaluated.
RESULTSBoth sperm DNA fragmentation and chromatin packaging defect had a negative correlation with fertilization rate (r=-0.198, P<0.05, and r=-0.389, P<0.01, respectively). Both parameters were higher in couples who failed to achieve pregnancy than those who achieved clinical pregnancy (10.74% vs. 5.40%, P<0.01 and 23.58% vs. 11.83%, P<0.01, respectively).
CONCLUSIONAbnormality of sperm chromatin structure is one of the reasons for IVF-ET failure. Examination of sperm chromatin structure is helpful in predicting the risk of IVF-ET failure and optimizing treatment of infertility.

OBJECTIVETo explore the use of L-carnitine before percutaneous epididymal sperm aspiration-intracytoplasmic sperm injection (PESA-ICSI) in the treatment of obstructive azoospermia.
METHODSSeventy-nine cases of obstructive azoospermia treated in our center from Sep 2008 to Aug 2009 were divided into an L-carnitine (n = 43) and a control group (n = 36), the former given oral L-carnitine at 1 g bid for 3 months before PESA-ICSI, while the latter left untreated. Comparisons were made between the two groups in the number of retrieved oocytes and fertilized oocytes as well as the number and rate of good embryos.
RESULTSThere were no significant differences between the two groups in the number of retrieved oocytes and fertilized oocytes. But the number and rate of good embryos were significantly higher in the L-carnitine than in the control group (P < 0.05).
CONCLUSIONThree-month oral medication of L-carnitine before PESA-ICSI can raise the number and rate of good embryos in obstructive azoospermia patients and therefore benefit the therapeutic outcome.

Objective To describe the trend of overall mortality and major causes of death in Shandong population from 1970 to 2005,and to quantitatively estimate the influential factors.Methods Trends of overall mortality and major causes of death were described using indicators such as mortality rates and age-adjusted death rates by comparing three large-scale mortality surveys in Shandong province.Difference decomposing method was applied to estimate the contribution of demographic and nondemographic factors for the change of mortality.Results The total mortality had had a slight change since 1970s,but had increased since 1990s.However,both the mortality rates of age-adjusted and age-specific decreased significantly.The mortality of Group Ⅰ diseases including infectious diseases as well maternal and perinatal diseases decreased drastically.By contrast,the mortality of non-communicable chronic diseases (NCDs)including cardiovascular diseases(CVDs),cancer and injuries increased.The sustentation of recent overall mortality was caused by the interaction of demographic and non-demographic factors which worked oppositely.Non-demographic factors were responsible for the decrease of Group Ⅰ disease and the increase of injuries.With respect to the increase of NCDs as a whole.demographic factors might take the full responsibility and the non-demographic factors were the opposite force to reduce the mortality.Nevertheless,for the increase of some leading NCD diseases as CVDs and cancer,the increase was mainly due to non-demographic rather than demographic factors.Conclusion Through the interaction of the aggravation of ageing population and the enhancement of non-demographic effect,the overall mortality in Shandong would maintain a balance or slightly rise in the coming years.Group Ⅰ diseases in Shandong had been effectively under control.Strategies focusing on disease control and prevention should be transferred to chronic diseases,especially leading NCDs,such as CVDs and cancer.
