Objective: To investigate the prevalence and influencing factors of depressive symptoms among grassroots healthcare workers in Zhejiang Province, so as to provide insights into improving their mental health. Methods: Grassroots healthcare workers of community health service centers and township health centers were sampled from one county (city, district) in each of 11 cities in Zhejiang Province using a convenience sampling method from December 2022 to January 2023. Participants' gender, age, educational level and average daily sleep duration in the past week were collected through questionnaires, and depression symptoms was investigated according to Self-rating Depression Scale. Factors affecting the depressive symptoms were identified using a multivariable logistic regression model. Results: A total of 1 946 questionnaires were distributed, and 1 945 valid questionnaires were recovered, with an effective response rate of 99.95%. There were 444 boys, accounting for 22.83%, and 1 501 girls, accounting for 77.17%. The median age was was 36 (interquartile range, 44) years. There were 786 healthcare workers detected with depressive symptoms, with a prevalence rate of 40.41%, and the prevalence rates of mild, moderate and severe depressive symptoms were 26.94%, 10.49% and 2.98%, respectively. Multivariable logistic regression analysis identified age (50 years and older, OR=0.572, 95%CI: 0.386-0.846), annual income (100 000 to 149 999 Yuan, OR=0.780, 95%CI: 0.635-0.958; 150 000 to 199 999 Yuan, OR=0.463, 95%CI: 0.282-0.760; 200 000 Yuan and above, OR=0.303, 95%CI: 0.098-0.937), vocation (nurse, OR=1.593, 95%CI: 1.252-2.027) and sleep duration (less than 7 hours, OR=2.164, 95%CI: 1.768-2.648) as factors affecting depressive symptoms among grassroots healthcare workers in Zhejiang Province. Conclusions The prevalence of depressive symptoms among grassroots healthcare workers in Zhejiang Province is 40.41%. Age, annual income, job and sleep duration may affect the development of depressive symptoms among grassroots healthcare workers.

Primary aldosteronism(PA) is a common cause of secondary hypertension, with adrenal vein sampling(AVS)being the gold standard for etiological typing diagnosis. This retrospective study analyzed data from patients diagnosed with PA who underwent AVS or unilateral adrenalectomy at Nanjing Drum Tower Hospital′s Endocrinology Department from July 2018 to August 2021. Using multivariate logistic regression analysis, factors associated with unilateral aldosterone hypersecretion were identified. Based on these factors, a predictive model for diagnosing unilateral primary aldosteronism(UPA)was established: age <40 years, plasma aldosterone concentration(PAC)>15 ng/dL, adrenal CT indicating an unilateral typical adenoma, and spontaneous hypokalemia. This predictive model could help 14% of PA patients avoid unnecessary AVS procedures.

Objective:To explore the pathological characteristics of adrenal masses based on various tumor diameter and unenhanced computed tomography(CT) attenuation value, and evaluate the value of the two parameters in the assessment of the benign and malignant nature of adrenal masses.Methods:The data of 1 367 patients who underwent adrenalectomy in Nanjing Drum Tower Hospital from January 2017 to October 2022 were retrospectively collected. The adrenal masses were divided into four groups according to tumor diameter and unenhanced CT attenuation value, and the clinical and histopathological characteristics of the four groups were compared respectively. Logistic regression was used to analyze the correlation between tumor diameter, non-contrast CT attenuation value and malignant adrenal masses, and receiver operating characteristic(ROC) curve was used to assess the diagnostic value of both in benign and malignant adrenal masses.Results:The proportion of adrenocortical carcinoma and other malignant tumors increased with the rise of tumor diameter or unenhanced CT attenuation value. After adjusting for age and gender, tumor diameter( OR=1.624, 95% CI 1.464-1.803, P<0.001) and unenhanced CT attenuation value( OR=1.108, 95% CI 1.079-1.138, P<0.001) were predictors of malignant adrenal masses. The tumor diameter and unenhanced CT attenuation value in diagnosing malignant adrenal masses had area under the ROC curve(AUC) of 0.838 and 0.892, respectively. With the optimal cut-off values of >3.4 cm and >30 HU, the sensitivity was 75.5% and 83.7%, and the specificity was 80.5% and 84.4%, respectively. The combination of tumor diameter >3.4 cm and unenhanced CT attenuation value >20 HU had an AUC of 0.927, with a sensitivity of 71.4% and a specificity of 90.1% in diagnosing malignant adrenal masses. Conclusions:Tumor diameter and unenhanced CT attenuation value has important significance in the differential diagnosis of benign and malignant adrenal masses. A combination of tumor diameter (>3.4 cm) and unenhanced CT attenuation value (>20 HU) demonstrates best diagnostic efficiency. Clinical application of this combined index can effectively diagnose malignant adrenal masses while avoiding unnecessary investigations or surgery.

Objective:To identify the clinical and pathological characteristics of adrenocortical carcinoma(ACC) with hypercortisolism and analyze the prognostic factors.Methods:Clinical data of ACC patients between January 2003 and December 2022 from Nanjing Drum Tower Hospital were collected retrospectively. Clinical and pathological characteristics were compared between ACC patients with hypercortisolism and nonfunctional ACCs. Kaplan-Meier method was used for survival analyses and Cox regression models were performed to analyze prognostic factors for ACC patients.Results:In 61 cases of ACC patients, the average age was (49.33±16.32) years. After a median follow-up of 77 months(95% CI 47.49-106.51 months), median overall survival and progression-free survival were 50 months(95% CI 20.44-79.56 months) and 29 months(95% CI 22.87-35.13 months), respectively. Among 36 patients with complete endocrinologic evaluations, 19(52.77%) were diagnosed with hypercortisolism. Compared with nonfunctional ACC, patients with hypercortisolism had more hypokalemia(42.11% vs 6.25%, P=0.022), capsular invasion(68.42% vs 25.00%, P=0.018), and distant metastases(73.68% vs 25.00%, P=0.007). Median overall survival and progression-free survival were significantly shorter than nonfunctional ACC(overall survival: 39 months vs 67 months, P=0.009; progression-free survival: 30 months vs 51 months, P=0.040) as well. Multivariate Cox regression analyses indicated that Ki67 index( HR=1.078, P=0.024) was an independent risk factor for overall survival. Hypercortisolism( HR=71.112, P=0.006), Ki67 index( HR=1.345, P=0.003), adjuvant therapy( HR=176.652, P=0.012), and operation( HR=0.020, P=0.003), were associated with disease progression. Conclusion:ACC accompanied by hypercortisolism is more prone to invasion and distant metastasis, resulting in shorter survival. Hypercortisolism is an independent prognostic factor for ACC patients.

OBJECTIVE To establish the quality standard of Clinopodium gracile. METHODS Ten batches of C. gracile were collected to perform appearance and property identification， microscopic identification and thin layer chromatography （TLC） identification. Moisture， total ash， acid-insoluble ash and dilute ethanol extract were detected， and the content of rosmarinic acid was determined by HPLC. RESULTS The stem of C. gracile was slender， square columnar， covered by white fluff， the surface was grayish green or greenish brown； epidermal cells， non-glandular hairs， cortical cells and so on were seen in the cross section of the stem. Non-glandular hairs， ducts， wood fibers， mesophyll cells and so on could be seen in the powder. Results of TLC identification showed that there were spots of the same color in the chromatographic position corresponding to the chromatographic position of buddlejasaponin Ⅳb control. The contents of water， total ash， acid-insoluble ash， dilute ethanol extract and rosmarinic acid in 10 batches of samples were 8.69%-12.33%， 5.96%-13.33%， 0.14%-3.29%， 18.57%-32.61%， 0.35%-0.82%， respectively. The average values were 10.10%， 9.73%， 1.06%， 23.54% and 0.56%， respectively. CONCLUSIONS The established method can be used for quality control of C. gracile. It is preliminarily proposed that the ash content in the herb should not exceed 12.0%， the total ash content should not exceed 12.0%， the acid-insoluble ash content should not exceed 1.5%， the dilute ethanol extract should not be less than 18.0%， and the rosmarinic acid content should not be less than 0.45%.
