ABSTRACT
Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.
ABSTRACT
In recent years, the "Room Escape" industry in China is booming, and this real live game has become popular. However, health threatening events such as fire, trauma, coma, and lung infection in the game venues have been reported at home and abroad. If these venues are not supervised in time, there will be great potential public safety and health hazards. In this review, we summarized the hidden dangers of public safety and health in such venues, including fire and safety hazards, persistent stress state, indoor ventilation problems, risk of contagious infection, non-player characters’ health risk, special film effects of 4D cinemas, mosquito problems, light pollution and noise, and food safety. Meanwhile, health management recommendations for the game venues were proposed from the aspects of formulating health management standards, improving health security measures, and strengthening related health education to players, so as to improve the hygiene levels of such venues and protect players and staff from injuries or diseases.
ABSTRACT
Objective To evaluate the effect of resistance training on glucolipid metabolism in a population with pre-diabetic metabolism (PDM).Methods Sixty persons with PDM were randomly divided into a resistance training group,an aerobic training group and a control group,each of 20 members.The exercise intervention groups exercised 3 times a week for 12 weeks in accordance with the exercise prescription,while the control group was without any regular aerobic exercise or resistance training.Before and after the 3 months of exercise training,fasting blood glucose (FBG),2 hours postpradial blood glucose (PBG),HbAlc,and lipid profile were tested.Body mass index (BMI),waistline,and blood pressure were also measured.Results Before the intervention,there were no significant differences in any of the average values among the 3 groups.In the resistance group,the average FBS (5.52 ± 0.52 mmol/L),HbA1 c (5.92 ± 0.36％) and TG (1.65 ± 0.92 mmol/L) had all decreased significantly after the training.In the aerobic group the average waistline,dilated blood pressure,FBG and HbAlc had decreased significantly.In the control group the average 2hrs PBG and LDL-C had both increased significantly compared to 3 months earlier.Compared with the resistance group,the average 2hrs PBGs were significantly higher in both the aerobic and control groups after the training.Moreover,compared with the aerobic group,the value in the control group was also significantly higher.Conclusion Both resistance training and aerobic exercise can lower fasting blood glucose and HbA1 c in PDM patients without obvious effect on BMI or low density lipoprotein level.Compared with aerobic exercises,resistance training had significant advantages in decreasing 2-hour postprandial blood glucose.
ABSTRACT
Objective To envaluate the accuracy of Photoplethysmograph pulse wave in monitoring stress reaction to harmful stimulation. Methods Patients (n=75) were randomly assigned to three groups according to the dosages of fentanyl that were administrated ( 4, 5 and 6 g/kg were given to F4, F5, F6 group respectively (n=25) in each group. Heart rate (HR), Systemic blood pressure (SBP), Diastolic blood pressure (DBP), SpO2, the skin temperature of finger, perfusion index (PI), epi?nephrine(E) and Norepinephrine (NE) were recorded at following time points:just in operation room (T1), 2 min after induc?tion (T2), at intubation (T3),1 min (T4) and 5 min (T5) after intubation. And the PPGPW was printed and measured at the same time points. Results PPGA and PI were significantly increased while E and NE were significantly decreased in T2 and T5, compared with those baseline at T1 (P < 0.05). At T3, PPGA and PI were significantly decreased while NE markedly in?creased in group F4 and F5 compared to T1. At T3, E in group F4 were remarkably increased h while E in group F5 were of no obvious changed, compared with those at T1(P<0.05). PPGA and PI increased while E and NE decreased in group F6 at T2, T3 ,T4 and T5 compared with those at T1 (P<0.05). In summary, PI was negatively correlated with plasma E and NE while PP?GA was negatively correlated with plasma E and NE .Conclusion PPGA and PI are negatively associated with intensity of stress response. And they can reflect the stress reaction during the induction period of intravenous anesthesia accurately.

ABSTRACT
Objective To translate the Female Sexual Function Index(FSFI) into Chinese and establish its psychometric properties among ordinary Chinese people and diabetes patients.Methods A two-phase study design was applied.The Chinese version of FSFI was established by translation and back translation,then the reliability and validity of the FSFI were evaluated.Results The content validity coefficient of FSFI was 0.953.The test-retest reliability in each dimension had good correlations (r value was 0.817～0.922),with the highest correlation coefficient in vaginal lubrication dimension (0.922) and arousal dimension the minimum (0.817).In all samples (including diabetes and non diabetes) a reliability coefficients of the Cronbach alpha of each dimension was from 0.760 to 0.874.The Cronbach alpha of each dimension for the diabetic group was from 0.783 to 0.882,and from 0.757 to 0.865 in the non-diabetes group.Pearson correlation of each dimension was very good in total samples,the diabetes group,and the non-diabetes group.Conclusions The psychometric properties of the FSFI demonstrated satisfactory validity and reliability.The Chinese version of FSFI is a reliable and valid measure to evaluate the sexual function in Chinese women.
