Objectives To investigate the outcomes of neonatals with abnormal hepatitis B virus (HBV) serological markers. Methods Twenty-eight neonatals who had abnormal HBV serological markers and whose mothers had positive HBsAg, HbeAg and HbcAb were studied. Among them, 21 neonatals who had positive HBsAg, HbeAg and HbcAb were included in vertical transmission group;7 neonatals who had positive HbeAg, HbcAb and negative HBsAg were included in suspicious group. The quantities of HBV serological markers were determined by time-resolved immunofluorometric assay (IFMA) and the level of HBV DNA were measured by fluorescence quantitative PCR (FQ-PCR). Results Serum HBeAg and HBsAg levels in suspi-cious group were lower than those in vertical transmission group (P<0.05). The results showed that HBeAg level (0.55 ± 0.19 PEIU/ml) three months after birth was lower than that (4.02 ± 2.00 PEIU/ml) 7 days after birth in suspicious group (P<0.05). Conclusions Early interference has positive effect in mothers and neonatls with abnormal HBV serological markers.

OBJECTIVE: To investigate the current status and influencing factors of occupational stress in female workers of labor-intensive enterprises. METHODS: Totally 910 female workers from 5 labor-intensive enterprises in Guangdong Province was selected as the research subjects by random cluster sampling method. A questionnaire survey on occupational stress was conducted using the Occupational Stress Inventory-Revised Edition. RESULTS: Among the 910 female workers,14. 9%( 136/910) showed medium or higher scale on occupational role level,20. 1%( 183/910) showed medium or higher scale on occupational stress level,and 21. 4%( 195/910) showed medium or higher scale on personal resources lack. Multivariate logistic regression analysis indicated that the risk of occupational stress was high in single female workers and/or those exposed to occupational hazards( P < 0. 01). The higher the occupational role level,the higher risk of occupational stress( P < 0. 01). The less personal resources,the higher risk of occupational stress( P < 0. 01).CONCLUSION: Some female workers in labor-intensive enterprises showed medium or higher occupational stress level. The main influencing factors of occupational stress are marital status,exposure to occupational hazards,occupational role and personal resources.

OBJECTIVETo observe the difference between the combination therapy of alpha-interferon (IFN-alpha) therapy Yixuesheng Capsule and the monotherapy of IFN-alpha in treatment of chronic hepatitis B.

METHODA total of 288 patients with HBeAg-positive chronic hepatitis B proven by liver biopsy were included in this study. During the individualized therapy, they received hypodermic injection of IFN-alpha 1b, with 5 MU x time(-1) and three times x w(-1). Of them, 125 patients received combination therapy with Yixuesheng Capsule for three months, with 1.0 g/time and three times/d; and 163 patients received only IFN-alpha 1b (the IFN-alpha monotherapy group). After the course of therapy, all patients were followed up for at least 24 months. The intention-to-treat analysis was adopted for statistic analysis.

RESULTThe two groups showed no statistical significance by gender, age, liver necroinflammation grading, liver fibrosis staging, serum ALT levels, serum HBV DNA levels and IFN-alpha therapy course. The whole course and the 24-month follow-up visit cover all of 112 patients in the combination treatment group and 141 cases in the IFN-alpha monotherapy group. The response rates of the combination treatment group and the IFN-alpha monotherapy group were 48.0% (60/125) and 35.0% (57/163) (x = 4.980, P = 0.026) at the end of treatment, respectively, 45.6% (57/125) and 33.1% (54/163) (x2 = 4.645, P =0.031) at the end of 12-month-follow-up period, respectively, and 38.4% (48/125) and 32.5% (53/163) (x2 = 1.076, P = 0.300) at the end of 24-month follow-up period, respectively.

CONCLUSIONThe combination treatment with IFN-alpha and Yixuesheng Capsule shows a slightly better sustained efficacy on HBeAg-positive chronic hepatitis B patients compared with IFN-alpha monotherapy.

OBJECTIVE: To explore the status of occupational stress and its influencing factors in medical radiation workers using two occupational stress measurement models. METHODS: A total of 632 medical radiation workers from Guangdong Province were selected as the study subjects using cluster sampling method. Chinese version of Job Content Questionnaire and Effort Reward Imbalance Questionnaire were used to assess occupational stress with job demand-control( JDC) and effort-reward imbalance( ERI) models. RESULTS: The rate of occupational stress in the study subjects was 43. 8%( 277/632) using the JDC model. The rate of occupational stress was 38. 6%( 244/632) using the ERI model. The multivariate logistic analysis results showed that the risk of JDC occupational stress was higher in workers with more than 8 hours work daily and more than 40 hours weekly( P < 0. 01). The risk of ERI occupational stress was higher in the workers with age of30. 0-40. 0,public medical institutions,daily work more than 8 hours and weekly work more than 40 hours( P < 0. 01).CONCLUSION: Under the two theoretical models,medical radiation workers have a certain degree of occupational stress. The age,medical institution type,daily and weekly work hours are the main factors affecting occupational stress.

OBJECTIVE: To explore the effect of occupational stress on the level of salivary cortisol in electronic manufacturing workers. METHODS: Two hundreds and forty workers were selected as study subjects by cluster sampling method. The Job Content Questionnaire and the Effort-Reward Imbalance Questionnaire were used to investigate the level of occupational stress in the job demand control( JDC) model and effort reward Imbalance( ERI) model. The saliva samples of workers were taken to determine the cortisol levels. RESULTS: Among the 240 workers,172( 71. 7%) showed occupational stress based on JDC model and 59( 24. 6%) showed occupational stress based on ERI model. The level of salivary cortisol of the workers in the high occupational stress group of JDC and ERI model were higher than those of the low occupational stress group( P < 0. 01). The level of salivary cortisol was positively correlated with the score of job demands,external costs and internal inputs( P < 0. 01),and it was negatively correlated with score of return dimension( P < 0. 01). In the occupational stress of JDC model,job requirements and autonomy entered the regression equation( P < 0. 05),that explained the 14. 0% of the total variation of the equation. In the occupational stress of ERI model,job pay and return dimension entered the regression equation( P < 0. 05),that explained the 13. 0% of the total variation of the equation. CONCLUSION: There is a correlation between occupational stress and level of salivary cortisol in the electronic manufacturing workers. Salivary cortisol can be used as an indicator of occupational stress.
