Utilization and influencing factors of whole lung lavage for patients with pneumoconiosis in Chinese mainland from 2018 to 2021 / 中国职业医学

Objective: To evaluate the utilization and influencing factors of whole lung lavage (WLL) for patients with pneumoconiosis. Methods: A total of 10 524 pneumoconiosis patients who sought medical treatment from 2018 to 2021 were selected as the research subjects using a combination of stratified random sampling and non-random sampling methods. The patients were from 27 provincial administrative regions of Chinese mainland (excluding Shanghai City, Tianjin City, Hainan Province and Tibet Autonomous Region). The effects of demographic and sociological characteristics, disease-related factors, and economic and social security status on WLL utilization were analyzed. Results: The WLL rate of pneumoconiosis patients was 17.8% (1 871/10 524). The main reason for promoting WLL in pneumoconiosis patients was “doctor's advice”, accounting for 65.4%； followed by “known-pneumoconiosis-patients had WLL” and “patient's recommendation”, accounting for 24.1% and 18.1%, respectively. Multivariate logistic regression analysis showed that age, body mass index, smoking index, education level, survey area, source of patients, current employment status, nature of dust-exposed unit, stage of pneumoconiosis, type of pneumoconiosis, pneumoconiosis symptoms (coughing up phlegm, chest pain, dyspnea, joint pain), contraindications to WLL (tuberculosis, pulmonary heart disease), family annual income, medical insurance for urban employees, proportion of medical insurance reimbursement, disability benefits, and social assistance were the influencing factors of WLL utilization in pneumoconiosis patients (all P<0.05). Conclusion: A large proportion of pneumoconiosis patients used WLL. The influencing factors of WLL utilization included demographic and sociological characteristics, disease-related factors, economic and social security status, and more. It is necessary to protect the interests of pneumoconiosis patients, strengthen occupational health education and health promotion for pneumoconiosis patients, standardize the use of WLL in medical institutions, and make rational use of WLL.

Whole-body vibration exposure characterization in bus drivers of Haikou City: A comparison between two health risk assessment methods / 环境与职业医学

Background Long-term exposure to whole-body vibration (WBV) will affect the health of occupational drivers. However, research on the characteristics of WBV exposure by urban bus drivers and health risk evaluation is still insufficient. Objective To identify the characteristics of occupational WBV exposure of bus drivers serving 31 bus routes provided by three branches of Haikou Public Transport Group, and to evaluate their occupational health risks related to WBV. Methods A total of 31 out of 142 bus routes run by three branches of Haikou Public Transport Group were selected to monitor WBV exposure of 31 bus drivers during driving. WBV parameters such as triaxial frequency weighted acceleration (awx, awy, awz) and triaxial crest factor (CFx, CFy, CFz) of the drivers were determined with a six-channel human vibration meter. Two methods, 8-hour daily value of the weighted root mean square average weighted vibration [A(8)] based on aw and 8-hour daily value of vibration dose [VDV(8)] based on vibration dose value (VDV), were used for health risk assessment and classified WBV health risk results into three levels (high, medium, and low) by the exposure action value (EAV) and exposure limit values (ELV) for A(8) and VDV(8) recommended by ISO 2631-1:1997. The two evaluation methods, A(8) and VDV(8), were compared by Fisher's exact test. Results Regarding the WBV parameters, the vector sum of acceleration (av) was 0.321-0.680 m·s−2, the VDV of monitoring interval was 3.824-10.174 m·s−1.75, and the VDV(8) was 6.039-13.505 m·s−1.75; their values in mean ± standard deviation were (0.480±0.100) m·s−2, (6.987±2.737) m·s−1.75, and (9.773±4.540) m·s−1.75, respectively. Positive correlations were found between awx and awz, av and awz, CFx and CFy, CFy and CFz. No bus route's WBV exposure level was graded as high health risk by either A(8) or VDV(8). The number of routes graded as low health risk by A(8) was 26, while the number by VDV(8) was 12. The consistency rates of health risk levels evaluated by the two methods were 66.7% (6/9), 54.6% (6/11), and 45.5% (5/11) for the three bus group branches, respectively. The difference in WBV health risk assessment results between the two evaluation methods was not statistically significant. Conclusion Positive correlations are found between triaxial acceleration and triaxial crest factor. There is no difference in the results of using A(8) and VDV(8) to evaluate health risks of WBV in urban bus routes.

Study on the mechanism of LncRNA AC132217.4 regulating the proliferation and invasion of liver cancer cells / 国际外科学杂志

Objective:To investigate the effect of lncRNA AC132217.4 on the proliferation and invasion of liver cancer MHCC97-H cells and its molecular mechanism.Methods:The TCGA database was used to analyze the differential expression of AC132217.4 in liver cancer tissue and adjacent tissue, and to analyze the relationship between the expression level of AC132217.4 and the overall survival of liver cancer patients. Transfection of pcDNA-AC132217.4 plasmid into MHCC97-H cells was defined as AC132217.4 group, transfection of pcDNA plasmid into MHCC97-H cells was defined as negative control (NC) group, respectively. The proliferation and invasion ability of MHCC97-H cells were detected by MTT method and Matrigel invasion assay. The binding site between AC132217.4 and miR-18a-5p was analyzed by starBase v2.0 software and dual luciferase reporter gene assay. Real-time quantitative PCR (RT-qPCR) detected the differential expression of miR-18a-5p in the two groups of MHCC97-H cells. The expression of epithelial-mesenchymal transition protein was detected by Western-blotting. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between the two groups. Results:Compared with adjacent tissues, the expression of AC132217.4 was down-regulated in liver cancer tissues ( P<0.01). Compared with liver cancer patients with low expression of AC132217.4, the overall survival of liver cancer patients with high AC132217.4 expression was longer ( P<0.05). The pcDNA-AC132217.4 plasmid significantly inhibited the proliferation of MHCC97-H cells ( P<0.05). The number of invasive cells in the NC group and AC132217.4 group were (131.30±12.55) and (37.45±7.77), respectively. The pcDNA-AC132217.4 plasmid significantly inhibited the invasive ability of MHCC97-H cells ( t=6.36, P<0.01). AC132217.4 directly complemented miR-18a-5p ( P<0.01). The expression of miR-18a-5p in MHCC97-H cells in AC132217.4 group (1.04±0.30) was significantly lower than that in NC group (6.13±0.75) ( t=6.27, P<0.01). Compared with the NC group, the expressions of epithelial phenotype proteins Cytokeratin and Claudin-1 in MHCC97-H cells in AC132217.4 group were up-regulated, while the expressions of mesenchymal phenotype proteins Vimentin, Slug and Snail were down-regulated. Conclusions:The expression of AC132217.4 is low in liver cancer tissue, and it is related to the overall survival of liver cancer patients. AC132217.4 might inhibit the proliferation and invasion of liver cancer MHCC97-H cells by sponge miR-18a-5p.

Pathophysiological Mechanisms Underlying Unilateral Vocal Fold Paralysis in Female Patients: An Ultrasonographic Study

Objectives@#. Laryngeal ultrasonography (LUS) has been suggested as an alternative diagnostic tool for unilateral vocal fold paralysis (UVFP). The present study applied LUS and quantitative laryngeal electromyography (LEMG) in female UVFP patients to investigate the pathophysiologic mechanisms of UVFP. @*Methods@#. In this cross-sectional study, vocal fold (VF) length parameters included resting and phonating VF length measured using B-mode LUS, and color Doppler vibrating length (CDVL) measured using the color Doppler mode. @*Results@#. Forty female patients with UVFP were enrolled, among whom 11 and 29 were assigned to the thyroarytenoid (TA) muscle+cricothyroid (CT) muscle group (with CT involvement) and the TA (without CT involvement) group, respectively. In the TA group, the turn frequency in thyroarytenoid-lateral cricoarytenoid (TA-LCA) on the paralyzed side, as observed through LEMG, correlated with the VF length during the resting phase (R=0.368, P=0.050) and CDVL values (R=0.627, P=0.000) on the paralyzed side. In the TA+CT group, the turn ratio in the CT muscle correlated with the normalized phonatory vocal length change (nPLC; R=0.621, P=0.041) on the paralyzed side. @*Conclusion@#. CDVL and nPLC are two parameters that can be utilized to predict the turn frequencies of TA-LCA in UVFP cases without CT involvement, and the turn ratio of CT in cases of UVFP with CT involvement, respectively. The findings suggest that LUS, as a noninvasive tool, can serve as an alternative method for assessing the severity of laryngeal nerve injury and offer valuable insights into the pathophysiology of UVFP.

Adjustment of X-ray angle intraoperation based on the anatomic shape of femoral neck section / 解剖学报

[Abstract] Objective To investigate the appropriate X-ray angle which image can represent total proximal of femur according to the anatomic shape of the femoral neck section. Methods The anatomic parameter of the femoral neck section was observed and measured. Found the femoral neck was contained with three main surfaces of anterior surface, posterosuperior surface and posteroinferior surface. A model of surface fluoroscopy has been made by covering aluminum foil papers on the three surfaces of femoral neck. Taking the midpoint of the femoral neck as the fluoroscopy center, the C-arm was rotated at an interval of 10° between 0° and 170°, and the three aluminum foil paper models were taken for X-ray projection respectively. The X-ray angle with the smallest image of aluminum foil paper was taken as the appropriate X-ray angle of the surface. A penetrating model of the femoral neck internal fixation was made of three Kirschner wires penetrating through the anterior, posterosuperior and posteroinferior surfaces of femoral neck. The images of the penetrating Kirschner wires were observed through the traditional anteroposterior, lateral view and the three appropriate X-ray angle views obtained from the above test. Results The length of the three main surfaces accounts for 80. 95% of the circumference of the femoral neck. The anterior surface coronal angle was 18°, the posterosuperior surface coronal angle was 65°, and the posteroinferior surface coronal angle was 165°. The Appropriate X-ray angle of the three surfaces were 20°, 70° and 170° respectively. In the images of the three appropriate X-ray angles, the penetrating Kirschner wires of anterior surface, posterosuperior surface and posteroinferior surface of the femoral neck could be clearly observed respectively, while the penetrating Kirschner wire could not be completely found in the traditional anteroposterior and lateral images. Conclusion Traditional anteroposterior and lateral fluoroscopy can not accurately display the three-dimensional structure of femoral neck. By increasing the appropriate X-ray angle of 20°, 70° and 170°, the reduction quality and bony violation from internal fixation implants on the anterior surface, posterosuperior surface and posteroinferior surface of the femoral neck could be observed respectively.

Compared with the non-steatosis group, the minimal hepatic steatosis group had significantly higher levels of body mass index (BMI) (23.61±2.95 kg/m 2 vs 22.13±2.67 kg/m 2 , t =-4.150, P < 0.05), uric acid (UA) [333.0(291.0-375.5) μmol/L vs 287.5(244.8-345.3) μmol/L, Z =-3.620, P < 0.05], triglyceride [0.92 (0.66-1.14) μmol/L vs 0.77 (0.62-1.02) μmol/L, Z =-2.224, P < 0.05], and controlled attenuation parameter (CAP) [234 (214-258) dB/m vs 218 (201-237) dB/m, Z =-2.867, P < 0.05]. In the group with normal body weight, the patients with minimal hepatic steatosis had significantly higher levels of UA (333.0±63.9 μmol/L vs 291.0±72.8 μmol/L, t =-2.395, P < 0.05) a nd HBV DNA [4.44 (3.51-6.79) log 10 IU/mL vs 3.42 (3.00-5.03) log 10 IU/mL, Z =-2.474, P < 0.05]. BMI (odds ratio [ OR ]=1.223, 95% confidence interval [ CI ] : 1.086-1.378, P =0.001) and UA ( OR =1.006, 95% CI : 1.002-1.010, P =0.008) were risk factors for minimal hepatic steatosis in CHB patients, and UA ( OR =1.007, 95% CI : 1.001-1.013, P =0.022) was a risk factors for minimal hepatic steatosis in CHB patients with normal body weight. Conclusion Compared with the non-steatosis CHB patients, the CHB patients with minimal hepatic steatosis have a significantly higher proportion of patients with significant liver fibrosis and a significantly higher level of CAP. BMI and UA are independent risk factors for minimal hepatic steatosis in CHB patients, and for the CHB patients with normal body weight, elevated UA is closely associated with the onset of minimal hepatic steatosis.

Effect of Shugan Tiaoshen acupuncture combined with western medication on depression-insomnia comorbidity due to COVID-19 quarantine: a multi-central randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of Shugan Tiaoshen acupuncture (acupuncture for soothing the liver and regulating the mentality) combined with western medication on depression and sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, and investigate the potential mechanism from the perspective of cortical excitability.@*METHODS@#Sixty patients with depression-insomnia comorbidity due to COVID-19 quarantine were randomly divided into an acupuncture group and a sham-acupuncture group, 30 cases in each one. The patients of both groups were treated with oral administration of sertraline hydrochloride tablets. In the acupuncture group, Shugan Tiaoshen acupuncture was supplemented. Body acupuncture was applied to Yintang (GV 24+), Baihui (GV 20), Hegu (LI 4), Zhaohai (KI 6), Qihai (CV 6), etc. The intradermal needling was used at Xin (CO15), Gan (CO12) and Shen (CO10). In the sham-acupuncture group, the sham-acupuncture was given at the same points as the acupuncture group. The compensatory treatment was provided at the end of follow-up for the patients in the sham-acupuncture group. In both groups, the treatment was given once every two days, 3 times a week, for consecutive 8 weeks. The self-rating depression scale (SDS) and insomnia severity index (ISI) scores were compared between the two groups before and after treatment and 1 month after the end of treatment (follow-up) separately. The cortical excitability indexes (resting motor threshold [rMT], motor evoked potential amplitude [MEP-A], cortical resting period [CSP]) and the level of serum 5-hydroxytryptamine (5-HT) were measured before and after treatment in the two groups.@*RESULTS@#After treatment and in follow-up, SDS and ISI scores were decreased in both groups compared with those before treatment (P<0.05), and the scores in the acupuncture group were lower than those in the sham-acupuncture group (P<0.05), and the decrease range in the acupuncture group after treatment was larger than that in the sham-acupuncture group (P<0.05). After treatment, rMT was reduced (P<0.05), while MEP-A and CSP were increased (P<0.05) in the acupuncture group compared with that before treatment. The levels of serum 5-HT in both groups were increased compared with those before treatment (P<0.05). The rMT in the acupuncture group was lower than that in the sham-acupuncture group, while MEP-A and CSP, as well as the level of serum 5-HT were higher in the acupuncture group in comparison with the sham-acupuncture group (P<0.05).@*CONCLUSION@#Shugan Tiaoshen acupuncture combined with western medication can relieve depression and improve sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, which is probably related to rectifying the imbalanced excitatory and inhibitory neuronal functions.
