Objective To examine the relationship between the perioperative changes in cytokines and the postoperative complications after esophagecotomy. Methods Twenty-five ASA Ⅱ-Ⅲ patients undergoing esophagectomy were divided into two groups: group A without postoperative complication (n = 17), group B with postoperative complications including pulmonary infection (in 2 patients), pleural effusion (in 3 patients), cardiac arrhythmia(in 2 patients) and anastomosis hemorrage(in 1 patient) (n = 8). Blood samples were taken before anesthesia(T0 ), at skin incision(T1), 2h after chest was opened(T2 ), 60 min after lungs were inflated (T3) and 1,4, 24h after surgery (T4, T5, T6 ) for determination of serum IL-6, IL-8 and IL-10 concentrations. The durations of SIRS, the definition of which was set by American College of Chest Physicians /Society of Critical Care Medicine (ACCP/SCCM), was also recorded. Results The demographic data including age, sex and body weight were comparable between the two groups. There was also no significant difference in preoperative lung function, duration of surgery, blood loss during surgery and duration of unilateral lung ventilation between the two groups. The duration of SIRS was shorter in group A than that in group B. In both groups serum IL-6 and IL-8 levels increased significantly at T2 (after thoracotomy) reached their peak values at T4, and then gradually declined but were still significantly higher than the baseline values(T0). The serum IL-6 level was significantly higher at T6 (24h after surgery) in group B than that in group A. The serum IL-8 level was significantly higher at T3-6 in group B than that in group A. The IL-6/IL-10 and IL-8/IL-10 ratio were significantly lower at T5-6 in group A than those in group B. Conclusions The postoperative complications may occur due to the inflammatory response, and/or anti-inflammatory mediators insufficiency. The IL-6/IL-10 and IL-8/IL-10ratio may be of value in predicting the prognosis.

Objective To observe the illness change trend of drinking water type endemic arsenic poisoning in Qinghai Province, comprehensively evaluate the effect of prevention and control measures, in order to provide a scientific basis for timely adjustment of the prevention and control measures. Methods From 2010 to 2013, according to the Drinking Water Type Endemic Arsenic Poisoning Monitoring Programs, 3 villages in 2 counties within Qinghai Province were randomly selected as monitoring sites. The arsenic content in drinking water of residents was measured, water improvement projects in all monitoring villages were investigated; at the same time an investigation of arsenic disease in resident population was conducted, and urinary arsenic content was monitored. Arsenic in drinking water and urine was determined by hydride generation atomic fluorescence spectrometry, and arsenic poisoning was diagnosed using Endemic Arsenic Poisoning Diagnostic Criteria (WS/T 211-2001). Results Of the three water improvement projects, two were water arsenic exceeded the standard, and one was intermittently operated. From 2010 to 2013, the arsenic poisoning detec tion rate in Baoning Village was 27.30% (193/707), 31.90%(245/768), 29.35%(221/753) and 28.22%(219/776); in Kecai Village was 32.62%(107/328), 34.83%(124/356), 31.26%(131/419) and 29.35%(118/402);and in Manimotai Village was 56.58%(43/76), 52.81%(47/89), 45.10%(46/102) and 34.69% (34/98), there was no significant difference statistically of the arsenic poisoning detection rates in the three monitored villages in the 4 years (χ2 =3.09, 0.04, 0.92, all P>0.05). From 2010 to 2013, women arsenic poisoning detection rate was 36.45%(203/557), 40.59%(246/606), 36.12%(225/623) and 34.77%(218/627), respectively;men was 25.27%(140/554), 28.01%(170/607), 26.57%(173/651) and 23.57%(153/649), respectively;women arsenic poisoning detection rates were higher than those of men (χ2 = 16.25, 21.32, 13.49, 19.38, all P < 0.05). Arsenic poisoning detection rate of people younger than 60 years old had a tendency to increase with age. In 2012 and 2013, 105 and 93 urine samples were tested, respectively; urinary arsenic geometric mean was 0.113 and 0.149 mg/L. Conclusions Water improvement projects and water quality are not optimistic, and prevalence of arsenic poisoning is still at a higher level. A sound long-term monitoring program should be established as soon as possible, the management and maintenance of water improvement projects should be strengthened, and the monitoring and prevention work should not be neglected.

Objective:
To analyze the comparability of different detection systems and methods for tumor markers (TM) by reviewing the results of TM external quality assessment (EQA) in Shandong province during 2015 and 2017.
Methods:
The results of TM EQA from the Shandong Provincial Clinical Laboratory Center during 2015 and 2017 were collected, and grouped by the detection system or method. After outliers were removed by the CLInet EQA software, the mean and coefficient of variation (CV) in each group were calculated with median as the target value. The difference of TM results in different detection systems were compared by the Kruskal-Wallis H test.
Results:
Taking alpha-fetoprotein (AFP) as an example, the average CV of different detection methods of TM EQA during 2015 and 2017 ranged from small to large in order of microparticle enzyme immunoassay, electrochemiluminescence, acridine ester chemiluminescence and chemiluminescence. The trends of CV of the other tumor markers were similar to AFP. The average CV of individual marker in electrochemiluminescence group was lower than that in microparticle enzyme immunoassay group. The intra-group CVs of imported detection systems such as Roche, Beckman etc. were relatively ideal, and the average CVs of most tumor markers were less than 10%. However, the intra-group CVs of domestic detection systems such as Shenzhen Snibe, Zhengzhou Autobio etc. were not ideal, and the average CVs of most tumor markers were more than 10%. The target values of different detection systems varied with different items and batches, and there were great variation in carbohydrate antigen (CA) series.
Conclusion
The results of TM detected by the same automatic detection system are comparable. However, the results of TM detected by most different detection systems and methods are not comparable.

Objective:To investigate the longitudinal trajectory and influencing factors of cancer-related fatigue (CRF) in breast cancer patients during chemotherapy.Methods:From March 2019 to January 2020, breast cancer patients in Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine and Peking Union Medical College Hospital were selected as the research objects to conduct follow-up investigation. The survey tools included general information questionnaire, Cancer-related Fatigue Assessment Scale, International Physical Activity Questionnaire, and the Pittsburgh Sleep Quality Index Scale.Results:A total of 91 patients were included in the study. The incidence of severe CRF at each time point before chemotherapy, 3 weeks after chemotherapy and 6 weeks after chemotherapy were 1.1% (1/91), 8.8% (5/57) and 2.1% (1/48), respectively. The results of the generalized estimation equation showed that the trajectory of the total score CRF firstly increased and then decreased, reaching a peak at 3 weeks after chemotherapy (35.45±13.07), and mild CRF change showed statistical difference ( P<0.05). In addition, BMI and sleep and daytime dysfunction were the influencing factors of the total score of CRF. Disease stage, sleep disturbance and daytime dysfunction were the influencing factors of CRF with different severity. Conclusions:CRF is a prominent problem in breast cancer patients during chemotherapy. Attention should be paid to high-risk individuals with abnormal BMI and daytime function by medical staff.

Due to the physiological peculiarities of pregnant women, general clinical studies exclude pregnant women. Therefore, there is a lack of evidence of precise medication for pregnant women with diseases worldwide, which poses a significant risk for them to use medication during pregnancy. Whether to include pregnant women as subjects in clinical research has always been a focus of ethical discussion. By providing a broad overview of pregnant women’s participation in clinical research from an ethical perspective, this paper explored the risks and challenges faced by pregnant women’s participation in clinical research, and provided theoretical basis and thinking paths for how to fairly and effectively include pregnant women as subjects and promoting clinical research on pregnant women.
