Fifty-six cases of chronic low back pain were randomly divided into electroacupuncture group (n= 30) and control group (n= 26). Patients in electro-acupuncture group were treated with electro-acupuncture plus physical therapy, and patients in control group were treated with single physical therapy. The results showed that Electro-acupuncture plus physical therapy could obviously relieve pain, improve the patients' life quality, and its therapeutic effect was superior to that of the single physical therapy.

OBJECTIVE The aim of this study is to investigate the correlation between the spontaneous otoacoustic emission(SOAE)and transient evoked otoacoustic emission(TEOAE)in neonate. METHODS The subjects were 224 ears of 112 newborns(59 females, 53 males). The age of subjects ranged from 2 to 4 days (mean?SD: 2.68?0.74 day years). SOAE and TEOAE were measured with ILO96. RESULTS The correlation between SOAE number and TEOAE level were found (r=0.43, P

OBJECTIVE: To describe and analyze the clinical features of nasal respiratory epithelial adenomatoid hamartom and improve the levels of diagnosis and treatment. METHOD: Fourteen cases of nasal respiratory epithelial adenomatoid hamartom confirmed by pathology were collected and analyzed. RESULT: In 14 cases, primary complaint of Hyposmia(or Anosmia)and nasal obstruction were occured in 13 and 11 cases respectively. Four cases had past history of endoscopic sinus surgery because of the diagnosis of nasal polyps. Polypoid neoplasms could be seen in the bilateral olfactory clefts. Sinus CT showed soft tissue shadows in bilateral nasal cavity and mucous membrane thickening in different sinus. Endoscopic sinus surgery were utilized to eliminate focus in all cases. All cases weren t recurred after 2-20 months' following-up visitings. CONCLUSION Nasal respiratory epithelial adenomatoid hamartom is so rare that clinical and pathological doctors have limited knowledge of it. It has its own characteristics from the clinical symptoms, signs to sinus CT although they are nonspecific. So we should improve the understanding about it to avoid misdiagnosis or missed diagnosis.

Objective:To explore the mechanism of action of Lycii Cortex in the treatment of periodontitis based on network pharmacology and experimental validation. Methods:Traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) was used to screen the drug components of Lycii Cortex. Swiss Target Prediction was used to predict the action targets of the drug components. GeneCards was used to obtain the disease targets of periodontitis. Venny 2.1 was used to obtain the intersecting targets. Protein-protein interaction (PPI) network analysis was performed using the STRING, and network diagrams were constructed using Cytoscape. Gene ontology (GO) functional annotation and Kyoto encyclopedia of genes and genomes (KEGG) signaling pathway analysis were performed using Metascape. The Cytoscape software was used to construct "drug-target-pathway" network diagrams. The rats were randomly divided into model group and treatment group, with 5 rats in each group. After modeling for 8 weeks, the treatment group was injected with 1 ml of Lycii Cortex (150 mg Lycii Cortex Granules were dissolved in 1 ml water), and the model group was injected with the same amount of normal saline locally for 4 weeks. Results:A total of 10 active components of Lycii Cortex were founded. These components acted directly on 55 disease targets through multiple pathways to treat periodontitis. The results showed that β-sitosterol, stigmasterol, scopoletin, chrysin, atropine, and ivytin were the core components, and V-Rel reticuloendotheliosis hyperplasia viral oncogene homolog A (RELA), B-cell lymphoma-2 (Bcl-2), prostaglandin-endoperoxide synthase 2 (PTGS2), JUN, cysteinyl aspartate specific proteinase-3 (CASP3), tumor protein 53 (TP53), and nuclear receptor coactivator 2 (NCOA2) were important targets. GO analysis revealed that the most likely biological process (BP) associated with the intersecting genes was mainly involved in the response to steroid hormones, cellular response to organic ring compounds, programmed cell death positive regulation, response to hormones, apoptosis signaling pathway, leukocyte apoptotic process, positive regulation of neuronal apoptotic process, response to oxygen levels, positive regulation of apoptotic process, etc. The cellular component (CC) of the Lycii Cortex was mainly involved in the outer membrane of organelles, outer membrane, transcriptional regulatory complex, outer membrane of mitochondria, RNA polymerase Ⅱ transcriptional regulatory complex, mitochondrial membrane, membrane rafts, membrane microregion, perinuclear region of cytoplasm, etc. The molecular function (MF) of the Lycii Cortex was mainly involved in protein structural domain-specific binding, transcription factor binding, cysteine-type endopeptidase activity involved in apoptotic signaling pathway, DNA-binding transcription factor binding, RNA polymerase Ⅱ-specific DNA-binding transcription factor binding, cysteine-type endopeptidase activity involved in apoptotic process, general transcription initiation factor binding, ubiquitin protein ligase binding, ubiquitin-like protein ligase, etc. The results of KEGG analysis suggested that dermatophytes were mainly involved in the apoptotic process through p53, apoptosis, advanced genetically engineered end products and their receptors (AGE-RAGE), phosphatidylinositol 3-kinase-protein kinase B (PI3K-Akt), interleukin-17 (IL-17), hypoxia-inducible factor-1 (HIF-1), tumor necrosis factor (TNF), mitogen-activated protein kinase (MAPK), and nuclear factor-κB (NF-κB) signaling pathways for the treatment of periodontitis. Animal experiments showed that diclofenac could significantly improve periodontitis, as well as improve the expression levels of RELA, Bcl-2, PTGS2, JUN, CASP3, TP53, and NCOA2. Conclusions:Lycii Cortex mainly regulates enzymatic activity, anti-inflammatory, and other biological processes such as RELA, BCL2, PTGS2, JUN, CASP3, TP53, NCOA2, and other disease targets of the signaling pathways such as p53, apoptosis, AGE-RAGE, PI3K-Akt, IL-17, HIF-1, TNF, MAPK, and NF-κB, etc., to treat periodontitis.

Background Cumulative fatigue without intervention will seriously threaten the physical and mental health of workers. Shift work and life satisfaction are strongly associated with fatigue accumulation. Objective To explore the effects of life satisfaction, shift work, and their interaction on cumulative fatigue in petrochemical employees, and to provide a scientific basis for preventing cumulative fatigue. Methods All staff of a petrochemical enterprise were selected by cluster sampling for a cross-sectional study from July to October 2021 in Jiangsu Province. A questionnaire designed by the project team was used to collect information on shift work; and life satisfaction and cumulative fatigue were investigated by the World Health Organization Five-item Well-Being Index and the Self-diagnosis Checklist for Assessment of Worker’s Fatigue Accumulation respectively. A logistic regression model was used to analyze the influences of life satisfaction and shift work on cumulative fatigue. Multiplicative and additive models were applied to analyze the interaction effect of life satisfaction and shift work. Results A total of 4066 questionnaires were returned, of which 3763 were valid, with an effective recovery rate of 92.5%. The percentage of cumulative fatigue in the petrochemical employees was 63.2% (2377/3763), and the percentages of low life satisfaction and shift work in the petrochemical employees were 53.6% (2016/3763) and 54.2% (2041/3763), respectively. The results of univariate analysis showed no significant difference in cumulative fatigue among different marital status groups (P=0.176), and there were statistically significant differences in cumulative fatigue among the petrochemical employees in different groups of age, gender, educational level, average monthly income, job title, length of service, working hours, night shift, smoking, drinking, physical exercise, life satisfaction, and shift work (P<0.001). After adjustment for covariates such as age, gender, educational level, average monthly income, job title, length of service, working hours, night shift, smoking, drinking, and physical activity, the unconditional logistic regression model showed that the risk of reporting cumulative fatigue in high life satisfaction participants was 0.129 (95%CI: 0.109, 0.154) times of that in participants of low life satisfaction; the risk of reporting cumulative fatigue in shift work participants was 3.792 (95%CI: 2.713, 5.300) times of that in no shift work participants; and the risk of reporting cumulative fatigue in participants with both high life satisfaction and shift work was 0.105 (95%CI: 0.081, 0.135) times of that in participants with low life satisfaction and shift work. The relative excess risk due to interaction, the attributable proportion due to interaction, and the synergy index of coexisting life satisfaction and shift work were −5.504 (95%CI: −7.247, −3.760), −4.728 (95%CI: −7.575, −1.880), and 0.029 (95%CI: 0.002, 0.351) respectively, which suggested that life satisfaction and shift work have an additive interaction effect on cumulative fatigue. A significant multiplicative interaction was also found between life satisfaction and shift work (OR=0.688, 95%CI: 0.476, 0.936). Conclusion Life satisfaction and shift work are the influencing factors of cumulative fatigue among petrochemical employees, and they interact with each other on the risk of cumulative fatigue. High life satisfaction can reduce the risk of accumulated fatigue associated with shift work.
