Objective: To explore the psychological status and related factors in patients with precancerous of esophageal and gastric cardia in Linzhou of Henan. Methods: Clinical psycho-rating scale of Social Support Rating Scale (SSRS), Self-Rating Anxiety Scale (SAS, score ≥50 points with symptoms of anxiety) and Self-Rating Depression Scale (SDS, score ≥53 points with the symptoms of depression) were applied to survey life events and psychological status of subjects who aged 40-69 years old and participated in"The Early diagnosis and Early Treatment"program in Linzhou cancer hospital from July 2015 to Jan 2016. Patients with lower intraepithelial neoplasia or high-grade intraepithelial neoplasia were selected as precancerous lesions (n=118), and patients with normal grade were selected as healthy controls (n=210). Compare the differences of the scores between the two groups, and the logistic regression model was used to analyze the related factors of precancerous lesions and psychological status of the study subjects. Results: Precancerous lesions included esophageal (72 cases), gastric cardia (40 cases), esophageal and cardia dual source (6 cases); Precancerous lesions and healthy controls aged (57.17±7.71) and (53.12±7.99) years old, the difference was statistically significant (P<0.001). The anxiety and depression scale showed that the scores of SAS and SDS scores in the precancerous lesions were (37.18±10.01), (40.44±8.37) points, and (34.02±6.63), (38.49±8.73) points in control group, the difference was statistically significant (P=0.002, 0.032). While the social support total score (38.26±5.26), and subjective support score (24.08±3.83) and objective support score (7.50±1.89) in control group were all higher than those of precancerous group (36.80±6.18, 23.01±3.93, 6.93±1.57), and the difference were statistically significant (P=0.024, 0.016, 0.004). In addition, the Logistic analysis showed that subjects with low objective social support, subjective social support and anxiety symptoms were more likely to develop precancerous lesions, and the OR were 0.81, 0.72 and 1.05, respectively (P=0.028, 0.005, 0.009). Conclusion Social support, anxiety and depression status may be related to the occurrence and development of esophageal and gastric cardia precancerous lesions.

OBJECTIVETo understand the distribution of esophageal squamous cell cancer and precursor lesions in high-risk areas of China, and to provide evidence for determining the reference ranges of detection rates in high-risk areas.

METHODSEndoscopy with Lugol's iodine staining was performed on 15 709 local residents aged 40 to 69 years old in Linzhou of Henan province and Feicheng of Shandong province from 2005-2009. 35 cases without accurate pathology diagnosis and 11 cases with vital disease before screening were excluded. 15 663 subjects were enrolled in this study. Compliance was calculated by the percentage of the people who had endoscopic screening among the target population. Chi-square test and trend chi-square test were used to compare the distribution differences in age, gender and areas of esophageal squamous cell cancer and precancer. 95% CI of the detection rates was then employed to represent the reference ranges of esophageal squamous cell cancer and precursor lesions.

RESULTSThe compliance rate of screening endoscopy of this study was 49.36% (15 709/31 826) of all, and female's compliance (54.05%, 8 447/15 628) was much higher than that of male (44.83%, 7 262/16 198) (χ(2) = 88.14, P < 0.001). The detection rates of basal cell hyperplasia, low grade intraepithelial neoplasia, high grade intraepithelial neoplasia and esophageal squamous cell cancer of males were 4.17% (302/7 246), 17.22% (1 248/7 246), 1.67% (121/7 246), 0.83% (60/7 246), and were higher than that of females (3.45% (290/8 417), 14.82% (1 247/8 417), 1.41% (119/8 417), 0.48% (40/8 417), respectively). Except for high-grade intraepithelial neoplasia, the detection rates of male were higher than that of female (P values were 0.018, < 0.001, 0.960, 0.006). The detection rates of all grades of precursor lesions increased with age rising (all P values < 0.001), among which the detection rates of the mentioned four lesions for 40-44 years old were 2.69% (94/3 500), 8.11% (284/3 500), 0.40% (14/3 500), 0.14% (5/3 500), and that of 65-69 years old were 5.46% (46/843), 23.25% (196/843), 3.68% (31/843), 2.14% (18/843). The proportion of esophageal precursor lesion of Linzhou were higher than that of Feicheng observably except for esophageal squamous cell cancer (P values were < 0.001, < 0.001, < 0.001, 0.437). The detection rates of the four lesions of Linzhou and Feicheng were 4.90% (504/10 287), 17.37% (1 787/10 287), 1.79% (184/1 0287), 0.60% (62/10 287) and 1.64% (88/5 376), 13.17% (708/5 376), 1.04% (56/5 376), 0.71% (38/5 376). The 95% CI of detection rates of various lesions were, 3.78% (3.48%-4.08%) for basal cell hyperplasia, 15.93% (15.37%-16.50%) for low-grade intraepithelial neoplasia, 12.31% (11.79%-12.82%) for mild dysplasia and 3.62% (3.33%-3.91%) for moderate hyperplasia, 1.53% (1.34%-1.72%) for high-grade intraepithelial neoplasia and 0.64% (0.51%-0.76%) for esophageal squamous cell cancer, respectively.

CONCLUSIONUp to 21.88% residents that were asymptomatic were suffered from esophageal squamous cancer or precursor lesions in high-risk areas in China. The distribution of esophageal squamous cell cancer and precursor lesions was closely related to the gender and the age, which suggested that males were supposed to be paid more attention to.

With continuous improvement of people's living standards, great efforts have been paid to environmental protection. Among those environmental issues, soil contamination by petroleum hydrocarbons has received widespread concerns due to the persistence and the degradation difficulty of the pollutants. Among the various remediation technologies, in-situ microbial remediation enhancement technologies have become the current hotspot because of its low cost, environmental friendliness, and in-situ availability. This review summarizes several in-situ microbial remediation technologies such as bioaugmentation, biostimulation, and integrated remediation, as well as their engineering applications, providing references for the selection of in-situ bioremediation technologies in engineering applications. Moreover, this review discusses future research directions in this area.
