ABSTRACT
Since December 2019, the corona virus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (2019-nCoV) has been reported in Wuhan, Hubei Province. Almost 70% of patients susceptible to 2019-nCoV are over age of 50 years, with extremely large proportion of critical illness and death of the elderly patients. Meanwhile, the elderly patients are at high risk of osteoporotic fractures especially osteoporotic vertebral compression fractures (OVCF). During the prevention and control of COVID-19 epidemic, orthopedists are confronted with the following difficulties including how to screen and protect OVCF patients, how to accurately diagnose and assess the condition of OVCF patients with suspected or confirmed COVID-19, and how to develop reasonable treatment plans and comprehensive protective measures in emergency and outpatient clinics. In order to standardize the diagnosis and treatment of patients with OVCF diagnosed with COVID-19, the authors jointly develop this expert consensus. The consensus systematically recommends the standardized emergency and outpatient screening and confirmation procedures for OVCF patients with suspected or confirmed COVID-19 and protective measures for emergency and outpatient clinics. Moreover, the consensus describes the grading and classification of OVCF patients diagnosed with COVID-19 according to the severity of illness and recommends different treatment plans and corresponding protective measures based on the different types and epidemic prevention and control requirements.

ABSTRACT
Objective To investigate the CT features of renal oncocytoma(RO),and to analyze the causes of misdiagnosis.Methods CT and clinical data of 1 2 patients with RO confirmed by surgery and pathology were analyzed retrospectively,the CT features and the causes of misdiagnosis before operation were analyzed and summarized.Results According to CT features before operation,among the 1 2 cases of RO,9 were misdiagnosed as renal carcinoma,3 were considered as benign occupying lesions.There were 6 cases located in the left kidney and 6 in the right kidney.Seven cases showed round mass and 5 showed irregular mass.Plain CT showed homogeneous masses in 6 cases and heterogeneous masses in 6 cases.Enhanced CT showed masses with homogeneous enhancement in 2 cases and masses with progressive enhancement in 10 cases.The attenuation value of parenchymal enhancement ranged from 41 to 143 HU (mean 90.17 HU).Seven cases had central scar syndrome,of which 1 case had calcification in the scar.One case showed segmental enhancement inversion,8 showed conical interface and 5 had holding ball signs.Conclusion The CT features of RO is central scar syndrome, segmental enhancement inversion,conical interface and holding ball sign,etc,but the definitive diagnosis still rely on pathology.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the prevalence and characteristics of childhood adverse experiences among adults aged 18-59 years and understand the association between childhood adverse experiences and risk of chronic diseases in adulthood.</p><p><b>METHODS</b>A cross-sectional study was conducted with a questionnaire among adults aged 18-59 years selected through cluster random sampling from 3 communities in Macheng, Hubei province. Uinivariate and multivariate logistic regression analyses were conducted to evaluate the association between adverse experiences in childhood and the risk of chronic diseases in adulthood.</p><p><b>RESULTS</b>A total of 1 767 adults aged 18-59 years were surveyed and 1 501 valid questionnaires were returned. The average age was (36.32± 10.20) years for males and (35.72±9.08) years for females. The prevalence rate of childhood adverse experiences was 66.22%. The risk of chronic disease in adults increased with the increase of the score indicating childhood adverse experiences (Z=-5.902 1, P<0.000 1). Multivariate logistic regression analysis showed that being physically abused (OR=1.93, 95% CI: 1.41-2.64), substance abuse in family (OR=2.82, 95% CI: 1.16-6.80), being bullied (OR=2.59, 95% CI: 1.39-4.80) and parents separation/divorce (OR=1.51, 95% CI: 1.09-2.09) were significantly associated with risk of chronic diseases in adulthood.</p><p><b>CONCLUSION</b>The prevalence of adverse childhood experiences was high in adults aged 18-59 years, which was significantly associated with the risk of chronic diseases in adulthood. Early prevention of chronic diseases should be conducted in childhood.</p>
ABSTRACT
@#Objective To investigate the special features of disabled children and their medical care before admission to social welfare institution.Methods A retrospective analysis of 306 cases was performed for the types of disabilities, growth and development, nutritional state, success rate in treatment of severe cases, and etc.Results In all of 306 cases (the ratio of male∶female equal 1.6∶1), 49 cases (16.01%) had intelligence disability, 17 cases (5.56%) had extremity disability, 6 cases (1.96%) had vision disability, 7 cases (2.29%) had hearing or speech disability, 158 cases (51.63%) had multiple disability, but no cases had psychiatric disability. Besides, 69 cases (22.55%) had severe but incurable or untreated congenital disease. 23 severe cases were successfully treated and there were 10 deaths. 296 cases were transferred to the state welfare institution after medical observation or treatment.Conclusion Living environment for disabled children is extremely bad, social adaptability is poor, most of them have growth retardation, malnutrition, poor immunity, susceptible to acute diseases and the mortality rate of these children is higher.
ABSTRACT
To study the mechanism of the innoxious touch-stimulus on the modulation of hyperalgesia and the expression of the C-fos and the nerve growth factor (NGF) receptor-TrkA in the spinal dorsal horn neurons following the chronic constriction injury (CCI) of the sciatic nerve in rats, 60female Sprague-Dawley rats were randomly divided into sham-operation group and CCI group, with each group being further divided into 3 subgroups on the 7th, 14 th and 28th day after operation (n=10). The mechanical and the thermal withdrawal threshold were assessed following the touch stiumulation after the CCI, immunohistochemical methods were employed to observe the expression of the C-fos and TrkA in spinal dorsal horn. Our results showed that the hyperalgesia appeared on the 4th day and reached the maximal level on the 14th day after operation. The expression of the C-fos also increased significantly and reached its maximal level on the 14th day after the touch-stimulus.Meanwhile, the TrkA expression was elevated significantly in both groups, as compared with basic data, and the difference was statistically significant (P＜0.05). It is concluded that the level of the C-fos expression changed with the paw withdrawal threshold variation and increased markedly following the innoxious touch-stimulus. The expression of the TrkA receptors also increased gradually following the development of the neuropathic pain. The results suggest that C-fos may play a crucial role in the development of the hyperalgesia in the earlier-time of the neuropathic pain, but TrkA receptors may be involved in the long-lasting adaptive changes of the central pathway in neuropathic pain.
