Objective: To investigate the mechanism of moxibustion in the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D), by observing the effects of moxibustion at Tianshu (ST25) and Shangjuxu (ST37) on microRNA-133b (miRNA-133b), pituitary homeobox family factor 3 (Pitx3)/tyrosine hydroxylase (TH), and neurotransmitters in the brain tissue of IBS-D rats. Methods: Healthy Sprague-Dawley rats were randomly divided into a normal group, a model group, a moxibustion group, and a Western medicine group, with 12 rats in each group. Except for the normal group, the IBS-D rat model was established by mother-offspring separation and acetic acid enema combined with restraint stress stimulation in all the other groups. No intervention was performed in the normal and model groups. Mild moxibustion was applied to both Tianshu (ST25) and Shangjuxu (ST37) in the moxibustion group. Rifaximin was given by gavage in the Western medicine group. The physical status of rats in each group was observed at different periods. After the intervention, hematoxylin- eosin staining was performed to observe the histopathological morphology of rat colon; enzyme-linked immunosorbent assay was used to measure the levels of dopamine (DA), noradrenaline (NE), and 5-hydroxytryptamine (5-HT) in plasma, colon, and midbrain tissue of rats; the relative expression levels of miRNA-133b, Pitx3 mRNA, and TH mRNA in the midbrain tissue were measured by real-time fluorescence quantitative polymerase chain reaction, and the relative expression levels of Pitx3 and TH proteins in the midbrain tissue were measured by Western blotting and immunofluorescence. Results: The body weights of rats among groups and at different time points were statistically different (P<0.01). The body weight of the normal group was higher than that of the other groups over time (P<0.01). After modeling, the minimum volume threshold of abdominal withdrawal reflex (AWR) was significantly lower (P<0.01) and the loose stool rate was significantly higher (P<0.01) in the model, moxibustion, and Western medicine groups compared with the normal group; the miRNA-133b expression in the midbrain tissue was significantly lower (P<0.01), the expression levels of Pitx3 and TH in the midbrain tissue were significantly higher (P<0.01), and the levels of DA, NE, and 5-HT in plasma, colon and midbrain tissue were significantly higher (P<0.01). After the intervention, the minimum volume threshold of AWR was significantly higher (P<0.01), the loose stool rate was significantly lower (P<0.01), the miRNA-133b expression was significantly increased (P<0.01 or P<0.05) and the expression levels of Pitx3 and TH were significantly decreased (P<0.01) in the midbrain tissue, the levels of DA, NE, and 5-HT in plasma, colon, and midbrain tissue were significantly reduced (P<0.01) in the moxibustion and Western medicine groups compared with the model group; the levels of 5-HT in the colon and midbrain tissue of the moxibustion group were significantly lower than those in the Western medicine group (P<0.05), and there was no statistical difference compared with the remaining groups (P>0.05). Linear correlation analysis showed that miRNA-133b was negatively correlated with Pitx3 (r<0, P<0.01); Pitx3 with TH, TH with DA, and NE with 5-HT were positively correlated (r>0, P<0.01).Conclusion: Moxibustion at Tianshu (ST25) and Shangjuxu (ST37) improves diarrhea symptoms and visceral hypersensitivity in IBS-D rats. The mechanism may be related to up-regulating miRNA-133b, inhibiting Pitx3/TH, and reducing neurotransmitter expression levels in the midbrain tissue.

OBJECTIVE: This experiment aims to determine the diagnostic value of diffusion-weighted imaging (DWI) in the differentiation of axillary inflammatory lymph nodes from metastatic lymph nodes in rabbit models in comparison with conventional magnetic resonance imaging (MRI). MATERIALS AND METHODS: Conventional MRI and DWI were performed at 4 weeks after successful inoculation into the forty female New Zealand white rabbits' mammary glands. The size-based and signal-intensity-based criteria and the relative apparent diffusion coefficient (rADC) value were compared between the axillary inflammatory lymph nodes and metastatic lymph nodes, with histopathological findings as the reference standard. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of the aforementioned criteria and rADC value in differentiating the axillary inflammatory lymph nodes from metastatic lymph nodes. RESULTS: Thirty-two axillary inflammatory lymph nodes and 46 metastatic ones were successfully isolated and taken into pathological analysis. The differences of the aforementioned criteria between the two groups were not statistically significant (p > 0.05). However, the rADC value of the inflammatory lymph nodes (0.9 +/- 0.14) was higher than that of metastatic ones (0.7 +/- 0.18), with significant difference (p = 0.016). When the rADC value was chosen as 0.80, the area under the ROC curve is greater than all other criteria, and the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for differentiating two groups were 86.2%, 79.3%, 81.2%, 84.2%, and 85.6%, respectively. CONCLUSION: Diffusion-weighted imaging is a promising new technique for differentiating axillary inflammatory lymph nodes from metastatic lymph nodes. Compared with routine magnetic resonance sequences, DWI could provide more useful physiological and functional information for diagnosis.

IFN-gamma and TNF-alpha were co-coupled to the polystyrene cell culture plate by the photo-immobilization method. To investigate the synergistic effect of IFN-gamma and TNF-alpha on the HeLa cells, HeLa cells were treated with co-coupled cytokine or non-coupled cytokine in a time course in this study. The morphology detection, cell cycle analysis by flow cytometry, phosphatidyl serine analysis and capase-3 activity detection demonstrated that the two kinds of treatments both induce HeLa cells apoptosis. Non-coupled cytokine worked more quickly while co-coupled cytokine kept more permanent effect. The caspase-3 activity assay indicated that the caspase-3 activity of HeLa cells treated with non-coupled cytokine is higher than that of HeLa cells treated with co-coupled cytokine. This may imply that co-coupled cytokine not only induces the caspase-dependent pathway, but also induces the caspase-independent pathway.

Objective: To investigate the prevalence and risk factors of neck and shoulder pain (NSP) among automobile manufacturing workers and to provide a theoretical basis for prevention of NSP. Methods: From November 5 to November 19, 2017, a total 446 works who had worked for more than one year were recruited from an automobile plant by cluster sampling method. Chi square test and unconditional logistic regression were used to exam the relation between influencing factors and NSP. Results: The annual prevalence rate of NSP was 34.8%. Multifactor regression analysis showed that age、work fatigue、department staff shortages、lifting heavy objects in awkward positions、neck flexion foreword and prolong sitting position work were the risk factors of NSP (OR=2.18, 95%CI:1.49~3.18; OR=4.52, 95%CI:1.27~16.00; OR=1.66, 95%CI:1.04~26.68; OR=2.10, 95%CI:1.16~3.81; OR=2.25, 95%CI:1.39~3.66; OR=2.42, 95%CI:1.06~5.56) and work break was the benefit factors of NSP (OR=0.58, 95%CI:0.36~0.94) . Conclusion The annual prevalence rate of NSP among automobile manufacturing workers was high. Lifing heavy objects、awkward working positions and unreasonable work arrangement were the major risk factors of NSP, and work break can effectively reduce the risk of NSP. Effective ergonomic intervention should be carried out to prevent the occurrence of NSP.

OBJECTIVE: To investigate the prevalence and influencing factors of low back pain in workers in automobile manufacturing plants. METHODS: A judgment sampling method was used to select 394 workers with working length ≥1 year in an automobile manufacturing plant as study subjects. A questionnaire survey was conducted to investigate the prevalence of low back pain in these workers using the Nordic Musculoskeletal Disorders Questionnaire. RESULTS: The prevalence of low back pain in these study subjects was 28. 9%( 114/394). The multivariate logistic regression analysis results showed that the relative risk ranked from high to low is as follow: uncomfortable working posture [Odds ratio( OR) =7. 31,95% confidence interval( 95% CI) = 2. 92-18. 28],feeling tired after work( OR = 5. 34,95% CI = 1. 22-23. 32],the commu time more than 30 minutes( OR = 2. 76,95% CI = 1. 38-5. 52),insufficient operating space( OR = 2. 22,95% CI = 1. 28-3. 83),hand or arm frequently used at work( OR = 2. 08,95% CI = 1. 14-3. 78) and age( OR = 2. 00,95% CI = 1. 19-3. 35),that were all risk factors of low back pain( P < 0. 05). CONCLUSION: The frequent use of hand or arm at work,insufficient operating space,uncomfortable working posture,feeling tired after work,and long commute time are the main influencing factors affecting the low back pain of automobile manufacturing workers.

Diabetic gastroparesis (DGP) is characterized by delayed gastric emptying caused by reduction of gastrointestinal motility. Its clinical manifestations include vomiting, nausea, belching, early satiety, postprandial fullness, and abdominal distention, etc. The mechanism of DGP is still not clear. Depletion of interstitial cells of Cajal, myopathy and neuropathy are considered to be the main pathogenic factors. Gastric prokinetics, gastric electric stimulation and endoscopic therapy are the main treatment options, but the long-term efficacy of these symptomatic treatment is not very satisfactory, which seriously affects patients' quality of life. This article reviewed the advances in study on pathogenesis and treatment of DGP.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective: To investigate the health of gypsum miners in Hubei province and analyze the health effects of occupational disease hazards exposure on gypsum miners. Methods: In April 2017, occupational disease hazard factors were tested on the site of a gypsum mine, and 500 workers were selected by random sampling to conduct questionnaires, relevant data such as occupational health examination was collected, and descriptive statistical analysis was performed. Results: The main occupational hazards of gypsum miners were gypsum dust and noise. The time-weighted average concentration of 8 h in the workplace was 4.32 to 9.34 mg/m³, and the post pass rate was 69.2% (9/13) ; Respiratory dust 0.13-5.15 mg/m³, post pass rate 75.0% (3/4). Gypsum miners had finger dysfunction and muscle numbness, joint pain (29.2%, 88/301) and chest pain and breathing difficulties (17.6%, 53/301). Followed by tinnitus, auricle pus, running water (4.7%, 14/301), abnormal muscle tension (2.7%, 8/301). The exposure of occupational disease hazards was associated with respiratory, auditory and neurological symptoms of gypsum miners. Conclusion The long-term exposure of gypsum workers to gypsum dust, noise and other harmful factors may result in obvious symptoms of respiratory system and other health damage.

Neck dissection for oral squamous-cell carcinoma (OSCC) is a clinically controversial issue and has therefore been the subject of abundant research. However, no one has performed a bibliometric study on this topic to date. The aim of this study was to assess the development of research on neck dissection for OSCC in terms of the historical evolution, current hotspots and future directions, particularly including research trends and frontiers from 2010 to 2019. Literature records related to research on neck dissection for OSCC were retrieved from the Web of Science Core Collection (WoSCC). CiteSpace was used as a tool to perform a bibliometric analysis of this topic. The survey included 2 096 papers. "Otorhinolaryngology" was the most popular research area. The most active institutions and countries were Memorial Sloan Kettering Cancer Center and the USA, respectively. Shah J.P. was the most cited author. Among the six identified "core journals", Head & Neck ranked first. The top three trending keywords were 'invasion', 'upper aerodigestive' and 'negative neck'. 'D'Cruz AK (2015)' was the most cited and the strongest burst reference in the last decade. The study evaluated the effect on survival of elective versus therapeutic neck dissection in patients with lateralized early-stage OSCC. The depth of invasion and the management of N0 OSCC were research frontiers in this field. The present study provides a comprehensive bibliometric analysis of research on neck dissection for OSCC, which will assist investigators in exploring potential research directions.
