Lumbar disc herniation(LDH)is a common and frequent disease,also one of the main causes of low back and lower limb pain.Radiomics can be used to improve early diagnosis of LDH,assist individualized treatment plan and evaluate prognosis.The research progresses of radiomics for early diagnosis and treatment of LDH were reviewed in this article.

Objective:To observe the occurrence and closure of iatrogenic atrial septal defect (IASD) after left atrial appendage occlusion (LAAo) and atrial fibrillation cryoballoon ablation (CBA), and to identify potential factors that may affect the occurrence of IASD.Methods:A total of 383 patients who underwent successful LAAo surgery in the Department of Cardiology at the Nanjing Hospital Affiliated to Nanjing Medical University from June 7, 2016 to December 2, 2020, and atrial fibrillation CBA surgery from December 29, 2016 to September 10, 2020 were retrospectively selected. Patients were followed up with echocardiography at 1 month, 3 months, 6 months, 1 year, and>1 year after surgery to determine the occurrence of IASD. The incidence of IASD between the two groups was compared, and clinical data between the two groups with and without IASD were analyzed to identify the relevant factors for the occurrence of IASD.Results:One month after CBA surgery for atrial fibrillation [73.8%(138/187) vs 47.9%(67/140), P<0.001], 3 months [39.0%(57/146) vs 13.6%(16/118), P<0.001], 6 months [17.7%(22/124) vs 3.6%(4/110), P=0.001], 1 year [11.8%(15/127) vs 1.8%(2/112), P=0.003], and one year later [9.8%(13/133) vs 0.9%(1/116), P=0.002], the incidence of IASD was significantly higher than those in LAAo. Compared with the non IASD group, the IASD group had a lower proportion of males [59.0%(121/205) vs 83.6%(102/122), P<0.001], and a higher proportion of paroxysmal atrial fibrillation [61.5%(126/205) vs 45.9%(56/122), P=0.006]. Logistic regression analysis found a significant correlation between women and CBA with postoperative IASD. Conclusions:Compared with LAAo, the incidence of IASD after CBA for atrial fibrillation is higher, and some IASD persist for more than 1 year after surgery. Women are significantly associated with IASD.

OBJECTIVES: To analyze the prevalence and influencing factors for drinking behavior and heavy drinking among government employees in Changsha and provide a basis for carrying out interventions for drinking behaviors and formulating public health promotion plans for government employees. METHODS: Government employees were recruited consecutively from the Health Management Center of a general hospital in Changsha between December 2017 and December 2018. Information on sociodemograpic characteristics, drinking behaviors, life events, and psychosocial characteristics was collected using a standard set of questionnaire. Drinking behavior was defined as drinking once or more per week for the past 12 months. The differences in drinking rates and excessive drinking rates among groups with different characteristics were compared. Multivariate analysis was performed to analyze the associated factors of drinking behaviors and heavy drinking for government employees. RESULTS: A total of 6 190 people completed this investigation. The overall drinking rate of government employees in Changsha was 21.9%, and the rate of drinking was higher in males than that in females (44.7% vs 4.0%, CONCLUSIONS The drinking and heavy drinking rates of government employees are high in Changsha. Marital status, physical exercise, and frequency of social intercourse are the common influencing factors of male drinking behavior and female drinking behavior. The life events stimulation is the influencing factor of heavy drinking.

Objective:To investigate association between loneliness and depressive episode among rural older people.Methods:A total of 839 rural adults (aged over 60 years) from Liuyang in Hunan were enrolled by using multi-stage cluster sampling method.The Short-form of the UCLA Loneliness Scale,the Social Support Rating Scale,the Life Events Scale for the Elderly,Quality of Life Scale,and the Activity of Daily Living Scale were used to assess loneliness,the social support condition,the stimulating quantity of negative life events,the quality of life,and the abilities of daily life activities,respectively.The Structured Clinical Interview for DSM-Ⅳ-TR Axis I Disorders questionnaire survey was performed by a face-to-face interview.Results:The prevalence rate of depressive episode among the rural older people was 6.8％.Multivariable analysis showed that the elderly who were with stronger loneliness were the risk factor of depression (OR=1.126,95％CI 1.038 to 1.221).Conclusion:Loneliness is positively associated with an increased risk of depressive episode.

Objective To understand the epidemiological characteristics of patients with advanced schistosomiasis in Hunan Province,so as to provide the evidence for formulating the advanced schistosomiasis prevention strategies and measures. Meth-ods The data of advanced schistosomiasis patients were collected and analyzed retrospectively with the cross section research method and description method in Hunan Province,2012. Results There were 5 722 advanced schistosomiasis patients in Hu-nan Province,and among them,4 112 patients were male(71.86%),and 1 610 were female(28.14%). Totally 5 311 patients came from the schistosomiasis endemic areas(92.82%)and 411 patients from non-schistosomiasis endemic areas(7.18%). The prevalence rate of advanced schistosomiasis was 8.46/10 000. The mean age of advanced schistosomiasis patients was 60.30 ± 11.63 years,and the youngest was 17 years old and the oldest 92 years old. In the age composition of advanced schistosomiasis pa-tients,the greatest number of cases was in the 60-70 years age group (32.72%). There were 3 595 cases of ascites type (62.83%),2107 cases of splenomegaly type(36.82%),11 cases of dwarf type(0.16%),and 11 cases of colon proliferation type (0.35%). Conclusion The prevalence rate of advanced schistosomiasis is relatively stable in Hunan Province,and the age of the patients showed an old aging trend. The salvation of advanced schistosomiasis patients in non-endemic areas should be strength-ened.

OBJECTIVE: To explore the reliability and validity of the short-form of the UCLA loneliness scale (ULS-8) among Chinese rural community-dwelling elderly. METHODS: ULS-8 was used for 839 Chinese rural community-dwelling elderly during face-to-face interviews. RESULTS: After deleting item-3 (I am an outgoing person) and item-6 (I can find companionship when I want it), the exploratory factor analysis showed that the construction of the new scale (ULS-6) fit the original construction of ULS-8, a single-factor resolution. Cronbach's α coefficient of ULS-6 was 0.831. Test-retest reliability was 0.715. All item-total correlations reached statistical significance. The total score of ULS-6 was correlated to quality of life, social support, suicidal ideation, and current major depression episode. CONCLUSION ULS-6 shows satisfactory reliability and validity and meets the needs of psychometric properties, and can be used for the evaluation of loneliness among Chinese rural elderly.
