Objective:This study investigated the prognostic significance of age at diagnosis, stage, tumor subtype, pelvic lymph node metastasis (PLNM), lymph-vascular space involvement (LVSI), presence or absence of deep cervical stromal invasion (DCSI) in stage ⅠB-ⅡA cervical cancer patients. It also investigated the inter-relationship among these factors. Methods: 152 patients treated with radical hysterectomy plus pelvic lymphadenectomy were followed up for a median of 49 months and were evaluated retrospectively. Results: The 5-year overall survival rate was 84.8%. The distribution of age at diagnosis is of bimodal shape, peaking at 42 and 68 years, respectively. Tumor subtype, PLNM, DCSI, and LVSI were found to be significant prognostic factors individually. After multivariate analysis, only tumor subtype and PLNM were found to be independent, significant prognostic factors for survival. The prognostic importance of LVSI appeared to be eclipsed by the presence of PLNM. DCSI was statistically related with FIGO stage, LVSI and PLNM. Conclusion: Tumor subtype and PLNM are the two most important independent prognostic factors for stages ⅠB-ⅡA cervical cancer. Some prognostic factors are inter-related and may reflect different facets of tumor progression.

AIM: To evaluate the physiologic change of retinal thickness during pregnancy.
METHODS:Forty cases ( 80 eyes ) were included two groups:40 eyes ( 20 cases ) in healthy pregnant women group (including in the second and last trimester), and 40 eyes (20 cases) in healthy nonpregnant women group ( control group ) . The macular volume, average thickness, central subfield thickness and retinal thickness of other parafoveal areas were measured by optical coherence tomography scan.
RESULTS: The macular volume was 10. 06±0. 41mm3 and 9. 87±0. 30mm3 in healthy pregnant women group and control group respectively. The average thickness was 279. 43±10. 86μm and 274. 25±8. 07μm in healthy pregnant women group and control group respectively. The central subfield thickness was 235. 15±15. 05μm and 233. 00±15. 81μm in healthy pregnant women group and control group espectively. Statistically significant difference was found in macular volume and average thickness (P<0. 05). The retinal thickness of 8 parafoveal areas in healthy pregnant women group increased comparing with control group, but statistical significance was only found in superior-outer area and inferior-outer area(P<0. 05). OCT images of all cases were normal.
CONCLUSION:The macular retinal thickness increases during pregnancy in the second and last trimester. The physiologic change of retinal thickness should be considered when evaluating pathologic retinal disease of pregnant women.

OBJECTIVETo analyze the epidemiological characteristics of occupational diseases in Guangzhou City, China in 2001 - 2010, and to provide a scientific basis for the prevention and control of occupational diseases.
METHODSStatistical analysis was performed on the reported data on the occupational diseases in Guangzhou from 2001 to 2010.
RESULTSA total of 380 cases of occupational diseases (37 types,8 classes) were diagnosed and reported in 2001 - 2010. The three most frequent diseases were occupational poisonings (48.9%), pneumoconiosis (20.0%), and occupational ear, nose, and throat (ENT) diseases (18.7%). In the cases of occupational poisonings, 25.3% suffered from acute occupational poisonings, especially the poisoning by dichloroethane (19.1%), and 74.7% suffered from chronic occupational poisonings, mainly caused by lead (38.8%), benzene (37.4%), and n-hexane (18.0%). The cases of silicosis accounted for 77.6% of all cases of pneumoconiosis. The cases of noise-induced deafness accounted for 97.2% of all cases of occupational ENT diseases. Patients with occupational diseases were reported in 13 districts of Guangzhou, mostly in Panyu (18.9%), Tianhe (13.2%), Baiyun (12.9%), and Liwan (11.1%). All the cases occurred in 19 industries, mainly including light industry (27.1%) and machinery industry (23.7%). Of all cases, 29.5% were in the public sector, 40.3% in the private sector, and 30.3% in the foreign-funded enterprises and those funded by businessmen from Hong Kong, Macao, and Taiwan. The ratio of male to female cases was 15:4. The mean age of onset was 42.2 ± 10.9 years. The average speed of development of occupational diseases was 134.0%, and the average growth rate was 34.0%.
CONCLUSIONThe incidence of occupational diseases tends to increase year by year, with younger age of onset and shorter history of exposure in patients. The occupational poisonings caused by lead, benzene, n-hexane, and dichloroethane, silicosis, and noise-induced deafness seem to be the main occupational hazards in Guangzhou, China. Occupational diseases occur in all districts of Guangzhou and in various industries. The private sector and small enterprises should be the focuses of occupational health supervision.
