Objective:To evaluate the safety and efficacy of endoscopic cryoablation (ECA) in patients with upper tract urothelial carcinoma (UTUC).Methods:The clinical data of 9 patients with UTUC treated with ECA from April 2018 to September 2019 were retrospectively analyzed. Patients consisted of 3 males and 6 females, with median age of 76 years old (ranging from 50 to 88 years old). Among the patients, 6 cases had tumors of ureter, 1 case had tumor of renal pelvis and 2 cases had tumors of renal pelvis combined with ureter. Of the 9 patients, two had bilateral UTUC, six were presented with single lesion, three were presented with multiple lesion. The size of tumors were (1.53±0.91)cm. The tumors of all cases were localized (≤stage T 2), and there was no carcinoma or suspicious lymph node/distant metastasis. All patients enrolled in this study had strong will to choose kidney-sparing therapy. Biopsy, resection of intraluminal lesion with laser and cryoablation under ureteroscopy or percutaneous nephroscopy was performed under general aneasthesia.Ureteroscopy was performed 3 months after cryoablation. Perioperative complications and follow-up results were recorded and assessed. Results:Cryoablation was successfully performed in patients under ureteroscopy (n=8) or nephroscopy (n=1). The median cryoablation time was 6 (ranging from 4-16) minutes. The median follow-up was 16 months (ranging from 4-24 months). No tumor recurrence was observed at primary sites during follow-up. Two patients with multiple lesions were observed denovo ureteral neoplasms outside the primary sites 3 months and 6 months after cryoablation and treated with second cryoablation. One case died due to cardiovascular events 4 months after surgery. One patient underwent ureteral stricture during follow-up and received ureteroscopic balloon dilatation. No recurrent stricture was found in this case during the subsequent follow-up of 16 months. The other 5 cases showed no recurrence or complications like stricture during follow-up.Conclusions:ECA could probably be a promising treatment for localized UTUC. No recurrence in primary site and low incidence of ureteral stricture was observed during follow-up. The efficacy and safety of ECA need to be verified with large sample study.

Objective:
To explore the occupational disease spatial distribution characteristics in Guangzhou and Foshan city in 2006-2013 with Geographic Information System and to provide evidence for making control strategy.
Methods:
The data on occupational disease diagnosis in Guangzhou and Foshan city from 2006 through 2013 were collected and linked to the digital map at administrative county level with Arc GIS12.0 software for spatial analysis.
Results:
The maps of occupational disease and Moran’s spatial autocor-relation analysis showed that the spatial aggregation existed in Shunde and Nanhai region with Moran’s index 1.727, -0.003. Local Moran’s I spatial autocorrelation analysis pointed out the "positive high incidence re-gion" and the "negative high incidence region" during 2006~2013. Trend analysis showed that the diagnosis case increased slightly then declined from west to east, increase obviously from north to south, declined from? southwest to northeast, high in the middle and low on both sides in northwest-southeast direction.
Conclusions
The occupational disease is obviously geographical distribution in Guangzhou and Foshan city. The corresponding prevention measures should be made according to the geographical distribution.

Objective:
To explore the relationship between occupational stress, psychological capital and depressive symptoms among electronic manufacturing female workers in the Pearl River Delta region.
Methods:
Using cluster sampling method, 845 female workers from 5 electronic manufacturing enterprises in the Pearl River Delta region were selected as research subjects from June to August 2017. The Effort Reward Imbalance questionnaire (ERI) , Psychological Capital questionnaire-24 (PCQ-24) and Patient Health questionnaire-9 (PHQ-9) were applied to measure the level of occupational stress, psychological capital and depressive symptoms in female workers.
Results:
Effort (

OBJECTIVE: To analyze the occupational stress status and its influencing factors in workers in labor intensive enterprises.METHODS: Two thousand eight hundred and ninety-four workers from 6 labor intensive enterprises were selected by cluster sampling method.The Occupational Stress Inventory-revised Questionnaire was used to evaluate their occupational stress.The influencing factors of occupational stress reaction were analyzed.RESULTS: Among the 2 894 workers,there were 76.1%,72.6% and 57.8% of workers at moderate levels on occupational stress,stress reaction and lack of coping resources,respectively.There were 17.0%,22.4% and 20.8% of workers at medium or above levels on occupational stress,stress reaction and lack of coping resources,respectively.The results of multiple linear regression analysis showed that the primary influencing factors of occupational stress reaction were role overload,role ambiguity,task conflict,sense of responsibility,working environment,recreation,rational handling,daily working hours,weekly working days and occupational hazards exposure(P<0.05).CONCLUSION: Most of the workers in labor intensive enterprises are at a moderate level of occupational stress.Some workers are at high occupational stress level.The occupational stress level,coping resources,working time and occupational hazards exposure can affect of the occupation stress response in these workers.

OBJECTIVE: To analyze the influencing factors that cause occupational stress among female workers in a large electronic manufacturing enterprise. METHODS: A total of 1 081 female workers from a large electronic manufacturing enterprise were selected by the cluster random sampling method. The Chinese version of Job Content Questionnaire and Effort Reward Imbalance Questionnaire were used to assess occupational stress and its influencing factors were analyzed.RESULTS: Among 1 081 female workers,70. 95% and 19. 43% of them showed high level of occupational stress of job demand-control( JDC) model and effort-reward imbalance( ERI) model,respectively. Educational level with senior high school and above,assembly line working and exposure to occupational hazards were risk factors for high occupational stress of JDC model in female workers( P < 0. 01). The risk of high occupational stress ERI model in female workers with junior high school educational level and below was higher than that of senior high school educational level and above( P < 0. 01).CONCLUSION: The occupational stress rate of female workers in this electronic manufacturing enterprise is high. The main occupational stress model is JDC model. The main influencing factors of JDC model are educational level,operation mode and status of occupational hazard exposure.
