Objective:To compare the efficacy of anhydrous ethanol and lauromacrogol in the treatment of ovarian endometriosis cyst (OEC), and to provide evidence for more effective use of these two sclerotic drugs.Methods:Thirty-three cysts in 30 patients with OEC, who were admitted to Taizhou Hospital of Zhejiang Province from February 2017 to June 2018, were treated by ultrasound interventional therapy, followed by catheter aspiration, saline cavity cleaning, anhydrous ethanol rinsing and sclerotherapy, and lauromacrogol alcohol 1∶1 mixed solution retained in the capsule (mixed group). The therapeutic effects were observed 6 and 12 months after operation. A total of 30 OEC in 28 cases admitted to the same hospital from 2013 to 2015 were retrospectively analyzed after similar treatment steps, but the intracapsular retention fluid was anhydrous ethanol (ethanol group). A total of 28 OEC in 26 patients admitted to the same hospital from 2015 to 2017 were washed with normal saline, then washed with lauromacrogol and retained in the capsule with lauromacrogol (lauromacrogol group). The therapeutic effects of 6 and 12 months after treatment between the three groups were compared.Results:According to the classification of cure, marked effect and inefficacy, there was a weak correlation among the three groups. The mixed group did not tend to be ineffective, while the lauromacrogol group tended to be ineffective 6 and 12 months after treatmen.the difference was statistically significant (adjusted standardized residual >2). According to the total effective (cure+ markedly effective) and ineffective classification, the effective rate of the mixed group was significantly higher than that of the lauromacrogol group ( P<0.016 7). There was no significant difference for the effective rate between the mixed group and the ethanol group, and between the ethanol group and the lauromacrogol group ( P>0.0167). Conclusions:The retention of ethanol-lauromacrogol mixture in the capsule of sclerotic OEC, after pre-rinsing with anhydrous ethanol is helpful to improve the curative effect of OEC and give full play to the therapeutic effect of common sclerosing agents used in ultrasound intervention.

Objective To evaluate the reliability of benign nodules diagnosed by ultrasound and analyze the probable factors of infecting the BI-RADS ultrasound categorization of breast lesions. Methods A total of 792 cases with initial category 3 assessments on BI-RADS ultrasound categorization consistent with more than 2 years follow-up or pathologic results were contained. The reliability of probable benign lesions were studied retrospectively,and several factors that could influence the categorization were explored such as age,breast lumps size,multiplicity,palpability,and US radiologist's experience referring to ACR-BI-RADS and the new categorizations recommendation. Results Of 792 breast nodules, 781 (98.6%) were benign and 11 (1.4%) were malignant. If the new categorizations recommendation was applied, 35. 1% (278/792) of all cased would have been upgraded to BI-RADS 4,81. 8% (9/11)of malignant tumors would have been found. The breast masses diagnosed by the junior radiologists were more frequently upgraded to BI-RADS 4 than senior radiologists' findings (P <0. 05), the nodules in women 40 years or older and multiple lesions were more frequently upgraded to category 4 (P <0. 01). The presence of palpability and mass size had on significantly influence the BI-RADS US categorization of breast nodules. Conclusions BI-RADS-Ultrasound categorization is relatively reliable to diagnose breast benign nodules. The multiplicity of breast nodules,patient's age and US radiologist's experience were found to have significant influences on the categorizations of probably benign breast nodules.

OBJECTIVES: Public service motivation refers to the idea of commitment to the public service, pursuit of the public interest, and the desire to perform work that is worthwhile to society. This study investigates how challenge stress and hindrance stress influence job performance among healthcare workers in Chinese public hospitals. It has also examined the mediating effect of public service motivation. METHODS: Data of 1594 healthcare workers were obtained from typical public hospitals in eastern, central, and western China. To test our hypotheses, we used descriptive statistical analysis, correlation analysis, structural equation modeling, and subgroup analysis to investigate the sample. RESULTS: Challenge stress and hindrance stress were strongly correlated among healthcare workers in Chinese public hospitals (β = 0.59; p < 0.001). Challenge stress was significantly positively associated with public service motivation (β = 0.14; p < 0.001) and job performance (β = 0.13; p < 0.001). Hindrance stress was significantly negatively associated with public service motivation (β = - 0.27; p < 0.001) and job performance (β = - 0.08; p < 0.05). Public service motivation was directly positively associated with job performance (β = 0.58; p < 0.001), and it indirectly mediated the association between job stress and job performance. CONCLUSIONS This study provides important empirical evidence on the effects of job stress and public service motivation on job performance among healthcare workers in Chinese public hospitals. Job performance may be raised by limiting hindrance stress, which provides moderate challenge stress and increases public service motivation.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

OBJECTIVES: We assessed the role of social support in presenteeism by examining organizational commitment among Chinese healthcare workers. METHODS: One thousand four hundred thirty-four healthcare workers from 6 hospitals in 4 Chinese cities completed a questionnaire measuring presenteeism, social support, and organizational commitment. With organizational commitment as the mediator, regression analyses and structural equation modeling were used to test the model. RESULTS: Organizational commitment was directly inversely associated with presenteeism (β = - 0.42, p < 0.001). Coworker support was moderately but significantly inversely associated with presenteeism (β = - 0.15, p < 0.001), but the path from supervisor support to presenteeism was not significant (β = 0.05, p > 0.05). The correlation between supervisor support and coworker support was significant (β = 0.71, p <0.001). Supervisor support and coworker support were significantly positively associated with organizational commitment (β = 0.41, p < 0.001, and β = 0.14, p < 0.001, respectively). CONCLUSIONS Supervisor support was more important in promoting organizational commitment, while coworker support was more effective in reducing presenteeism. The mediating effect of organizational commitment was significant.
