Objective To investigate the occupational health status of radiation workers in Dezhou, China, explore the effects of low-dose ionizing radiation on the health of radiation workers, and provide a basis for improving the health of radiation workers. Methods A total of 1101 radiation workers in Dezhou who underwent occupational health examination in 2021 were selected. The effects of physical examination type, type of work, sex, length of service, and age on the health status of radiation workers were compared and analyzed. Results The abnormal rates of abdominal color Doppler ultrasound and eye lens were significantly higher in pre-post radiation workers than in radiation works (P < 0.05). The abnormal rates of eye lens increased with the length of service in radiation workers (P < 0.05). The abnormal rate of abdominal color Doppler ultrasound in male workers was higher than that in female workers, while the abnormal rates of blood routine and thyroid function were higher in female workers than in male workers (P < 0.05). Conclusion The abdominal rates of color Doppler ultrasound and eye lens are relatively high among radiation workers in Dezhou. It is necessary to improve the protection awareness and strengthen the level of radiation protection, so as to ensure the occupational health of radiation workers.

Objective:To assess the differences in multidimensional clinical manifestations between patients with irritable bowel syndrome (IBS) matching the Rome Ⅲ criteria but not matching Rome Ⅳ and IBS patients matching the Rome Ⅳ criteria, among patients diagnosed with IBS according to Rome Ⅲ criteria.Methods:From November 2016 to October 2017, a total of 472 IBS patients admitted to six hospitals were selected, which included Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology (139 cases), Sir Run Run Shaw Hospital, School of Medicine of Zhejiang University (95 cases), the First Affiliated Hospital of Dalian Medical University (96 cases), the Affiliated Hospital of Guizhou Medical University (90 cases), the People′s Hospital of Guangxi Zhuang Autonomous Region (20 cases), and the Second Affiliated Hospital of Xi′an Jiaotong University (32 cases). The 472 IBS patients were divided into the group that matching the Rome Ⅳ criteria (Rome Ⅳ group), and the group that matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria (Rome Ⅲ group). The basic characteristics (IBS course, post-infectious IBS, history of smoking or drinking, etc.), abdominal symptoms, and defecation-related symptoms of two groups were compared and analyzed by face-to-face questionnaires. Multi-dimensional clinical manifestations assessment was completed by questionnaires, which included gastrointestinal symptom rating scale (GSRS), irritable bowel syndrome-severity scoring system (IBS-SSS), irritable bowel syndrome-quality of life (IBS-QOL), and hospital anxiety and depression scale (HADS). Independent sample t-test, rank sum test, and chi-square test were used for statistical analysis. Results:There were 344 patients (72.9%) in Rome Ⅳ group and 128 patients (27.1%) in Rome Ⅲ group. The IBS course of patients in Rome Ⅳ group was longer than that in Rome Ⅲ group (3.0 years (7.0 years) vs. 2.0 years (5.7 years)), and the difference was statistically significant ( Z=-2.73, P=0.006). The GSRS scores of loose stools and abdominal pain of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group, and the GSRS scores of increased exhaust and abdominal distension of IBS patients in Rome Ⅳ group were lower than those in Rome Ⅲ group (3.0(2.0) vs. 2.0(4.0), 3.0(2.0) vs.1.0(2.0), 1.5(3.0) vs. 2.0(3.0), 1.0 (3.0) vs. 2.0(3.0)), and the differences were statistically significant ( Z=-2.48, -9.90, -2.11 and -2.06, P=0.013, <0.001, =0.035 and =0.040). The proportions of fatigue and dizziness of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (58.4% (201/344) vs. 43.0% (55/128), 30.8% (106/344) vs. 29.7% (38/128)), and the differences were statistically significant ( χ2=8.37 and 12.36, P=0.004 and <0.001). The scores of anxiety and depression subscales of the HADS of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (6.5 (6.8) vs. 6.0 (6.0), 5.0 (6.0) vs. 3.0 (5.0)), and the differences were statistically significant ( Z=-2.58 and -2.40, P=0.010 and 0.017). The scores of IBS-SSS scale, abdominal pain severity, abdominal pain frequency, and impact on quality of life of IBS patients in Rome Ⅳ group were all higher than those in Rome Ⅲ group (249.5 (108.0) vs. 177.0 (111.8), 50.0 (25.0) vs. 20.0 (30.0), 50.0 (70.0) vs. 10.0 (30.0), 66.0 (42.0) vs. 42.5 (34.0)), and the differences were statistically significant ( Z=-7.79, -9.64, -10.65 and -2.48, P<0.001, <0.001, <0.001 and =0.013). The score of IBS-QOL for behavioral disorder of IBS patients in Rome Ⅳ group was lower than that in Rome Ⅲ group (74.5±21.6 vs. 79.2±17.7), and the difference was statistically significant ( t=-2.22, P=0.027). Conclusion:The clinical symptoms of patients mathching the Rome Ⅳ criteria are more typical and severe, as compared with those of IBS patients matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria.

Objective:To explore the feasibility of ultrasound screening and diagnosis of fetal cleft palate in early pregnancy, analyze and summarize the imaging technology and image characteristics of two-dimensional and three-dimensional ultrasound in normal fetus and cleft palate fetus.Methods:A total of 10 519 pregnant women participated in the early pregnancy were included from January 2016 to June 2020 in Shenzhen Hospital, University of Chinese Academy of Sciences. The palatal line on the standard section of fetal nuchal translucency (NT) measurement was used as a screening marker for routine observation. For fetuses with abnormal palatine line, posterior nasal triangle of coronal plane and axial plane of maxillary alveolar arch of two-dimensional ultrasound were added as the diagnostic sections, and three-dimensional volume data of fetal face were collected, and three dimensional multimodal imaging technology was used to analyze the volume data off-line to determine or exclude fetal severe cleft palate. All fetuses were followed up during the second trimester for deformity scanning and post natal (or induced labor) assessment.Results:Of the 10 519 fetuses, the standard NT plane was obtained and the palatal line was observed in 10 204 cases(97.01%), with normal palatal line in 10 169 cases.In 35 suspected cases, 13 cases were confirmed cleft lip and palate by two and three dimensions ultrasound, and were confirmed by induced labor. There were 7 cases in unilateral side, 3 cases in bilateral, 2 cases in median cleft lip and palate, 1 cases in irregular cleft lip and palate, and no false positive results were reported. Twenty-two suspicious cases were excluded by increasing the two-dimensional sectional and three-dimensional volumetric off-line analysis, and screening after the second trimester and after birth. There was 1 case of missed diagnosis of simple cleft palate.Conclusions:Palatal line is a good screening marker for fetal cleft palate in early pregnancy. For fetuses with abnormal palatine line, the adding of posterior nasal triangle and the axial plane of maxillary alveolar arch, and combining three-dimensional volume data for off-line analysis can determine or exclude severe cleft palate. This study is of great significance for early screening and diagnosis of severe fetal cleft palate, prenatal genetic counseling and prevention birth defect.

Objective: To investigate the effect of cognitive behavioural therapy (CBT), which is dominated by nurses, on depression in patients with acute leukemia. Methods: Patients with acute leukemia admitted to the Department of Hematology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine were evaluated with a rapid depressive symptom (QIDS-SR16) self-rating scale. Patients with a score higher than 11 were psychiatrists from the Shanghai Mental Health Center. Interviews and Hamilton Depression Rating (HAMD-17) assessment and clinical stereotype examination (SCID-I) diagnostic screening were performed. Patients with significant depressive symptoms who met the inclusion criteria were included (without considering DSM-5 diagnosis for depressive disorder). The computer random number method was assigned to the control group (group C), the therapist-led group CBT group (group T), the group CBT group with the nurse as the main body and therapists as the supervisors (group N). The group C was given the conventional method and the group T and N was given the standardized group CBT once a week for 8 weeks. Interviews were performed at baseline (before intervention), 4 weeks, and 8 weekends to assess the HAMD scale score. Results: Finally, 90 patients were enrolled, 30 in each group. At the end of the 4th week, the HAMD scale score (22.60±2.71) in the group T was lower than that before the intervention (25.77±2.93), and lower than the group N (24.57±2.82) and the group C (25.90± 3.88), the difference was statistically significant (t=5.395, 7.473, P<0.01 or 0.05). At the end of the 8th week, the group T (21.00±2.18) and the group N had a HAMD scale score (19.30±2.45) lower than the pre-intervention (25.77±2.93, 25.90±3.26), and were lower than the group C (24.80±3.56), the difference was statistically significant (t=6.192, 7.323, P<0.05 or 0.01). Conclusions CBT can improve the anxiety and depressive symptoms of patients with acute leukemia, and it is worthy of popularization and application.

Objective To explore the relationship and influencing factors between pre‐diabetes mellitus (pre‐DM) and hypertension, providing evidence for formulating strategies for cardiovascular disease prevention and control. Methods We conducted this study from June 2013 to September 2014. Using stratified multistage random sampling, participants were administered a questionnaire survey, their height, weight, waist circumference, hip circumference, other physical attributes, blood pressure and blood lipids were measured. They also underwent the 75‐g glucose tolerance test and other laboratory examinations. A logistic regression model was used to analyze the relationship between pre‐DM and hypertension and its influencing factors. Results A total of 4 002 participants completed the survey. Participants'mean age was 50.3 ± 11.8 years. Of the total participants, 1 962 (49.0%) were males, while 2 039 (51.0%) were females; 1 participant had missing gender data. Further, 2 188 participants had normal glucose metabolism, 1 066 had pre‐DM, and 748 had diabetes. The prevalence of hypertension in participants with normal glucose metabolism, impaired fasting glucose, impaired glucose tolerance, both impaired fasting glucose and impaired glucose tolerance, and DM was 28.3%, 46.5%, 46.3%, 62.0%, and 61.2%, respectively. The prevalence of hypertension varied among people with different glucose metabolism (χ2=306.672, P<0.001). The prevalence of hypertension in the pre‐DM population increased with the aggravation of abnormal glucose metabolism compared to the normal glucose metabolism population, with a linear trend (χ2=299.009, P<0.001). Among those with abnormal glucose metabolism, there were differences in age, cholesterol, triglycerides, low‐density lipoproteins, body mass index, and waist circumference compared to those without hypertension (P<0.05). The risk of hypertension in the pre‐diabetic population was 1.5 times higher than that in the normal glucose metabolism population (OR=2.510, 95% CI: 2.156-2.922, P<0.001). There was no difference in the correlation intensity between pre‐DM and hypertension when gender was taken into account. Age and lipid abnormalities slightly decreased the correlation intensity between abnormal glucose metabolism and hypertension. Considering body mass index and centripetal obesity, the correlation intensity between abnormal glucose metabolism and hypertension could be reduced by controlling these factors. Conclusion The prevalence of hypertension is high in people with pre‐DM. There is a correlation between pre‐DM and hypertension, even when considering factors such as age, dyslipidemia, body mass index, and centripetal obesity. Therefore, it is necessary to strengthen the management of blood pressure in the pre‐diabetic population; improve early intervention for risk factors such as dyslipidemia, body mass index, and centripetal obesity; and reduce the occurrence of hypertension.

BACKGROUND:Liver fibrosis is a kind of chronic and active disease that is caused by various causes and characterized by the excessive accumulation of extracelular matrix. At present, use of Chinese herbs for the treatment of hepatic fibrosis has obvious advantages. Salvia miltiorrhiza has been shown to be highly effective in the treatment of hepatic fibrosis. However, the underlying mechanism needs further investigation. OBJECTIVE:To investigate the effects of TanshinoneⅡA on the expression levels of transforming growth factor-β/Smads signaling pathway related factors transforming growth factor-β, bone morphogenetic protein 7, Smad6 and Smad7 in the liver tissue of rats with hepatic fibrosis. METHODS:SD rats were randomly divided into three groups (n = 10): normal control, model and TanshinoneⅡA-treated groups. Rats in the model and TanshinoneⅡA-treated groups were subtaneously injected with olive oil-diluted 10% CCl4 ( 5 mL/kg) twice a week, 8 weeks in total, to build rat models of hepatic fibrosis. Four weeks after hepatic fibgrosis induction, rats in the TanshinoneⅡA-treated group received subtaneous injection of TanshinoneⅡA til eight weeks. Rats in the normal control group were subcutaneously injected with olive oil. RESULTS AND CONCLUSION: Western blotting and reverse transcription-polymerase chain reaction (RT-PCR) detection showed that in the model group, the expression of transforming growth factor-β in the rat liver tissue was significantly increased (P < 0.01) and the expression of bone morphogenetic protein-7, Smad6 and Smad7 was significantly decreased (P < 0.01) compared with the normal control group. TanshinoneⅡA could obviously reverse the expression of those factors above-mentioned (P < 0.01). The results suggest that TanshinoneⅡA can be used for treatment of hepatic fibrosis by decreasing the expression of transforming growth factor-β and increasing the expression of bone morphogenetic protein-7, Smad6 and Smad7.
