To explore the mechanism of needling Ying method for treatment of sore throat. By the analysis of pathogenesis of sore throat, the authors think the key of its pathogenesis is stagnation of pathogenic factors such as hotness and phlegm accumulating, and meridian-vessel obstruction in the throat is its meridian foundation. There are several meridians passing through the throat, so the throat is closely related to viscera and meridians, and stagnation of pathogenic factors such as hotness and phlegm accumulating in the throat lead to sore throat when exogenous pathogenic factors invading or dysfunction of viscera and meridians. The treatment of needling Ying at local throat or combined with corresponding meridian point selection can dredge collaterals, dispel pathogenic factors, remove pathogenic factors to dispel swelling, resolve phlegm and dissipate stagnation and harmonize yin and yang, so as to relieve sore throat. In conclusion, needling Ying method is an important method in the treatment of sore throat.

OBJECTIVETo observe the effect of Coptidis Rhizoma (CR) on hemolysis and antioxidant system of normal mice and its impact on the functions, while evaluating the oxidation reduction property of CR and berberine.

METHODIn the whole animal experiment, normal mice were orally administered with CR at the dose of 1.2 g x kg(-1) for three days. Their blood were collected to detect the hemoglobin in plasma, the content of serum bilirubin, the number of peripheral blood reticulocytes, the T-AOC in whole blood, measure the contents of glucose-6-phosphate-dehydrogenase (G6PD), superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA) of RBC membrane, determine the activity of Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase, fluidity, and observe its impact on the liquidity and deformability of RBCs. According to the electrical and biochemical experiment, the voltammetric behaviors of CR and berberine on glassy carbon electrode were evaluated using cyclic voltammetry. In the RBC in vitro experiment, the impact of Coptidis Rhizoma on autoxidation hemolysis rate of RBCs of normal mice was observed.

RESULTThere was no significant effect on hemoglobin, serum bilirubin, and reticulocyte count in normal mice administrated with CR at the dose of 1.2 g x kg(-1), and so is on RBC membrane SOD, G6PD, MDA, GSH and whole blood T-AOC activity. In addition, CR had also no significant effect on Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase activity, and no notable impact on the fluidity and deformability of RBCs. There were two oxidation peaks at -0.27 V and 0.60 V induced by CR and one oxidation peak induced by berberine at 0.56 V, with no reduction peak at fly-back. CR could significantly inhibit oxidative hemolysis in RBCs at the dose of 0.125-2 g x L(-1) in vitro.

CONCLUSIONThe normal dose of Coptidis Rhizoma can not cause hemolysis of RBC, and also can not change antioxidant system and functions of RBC, CR and berberine show antioxidant (reducing) properties.

Background: Exposure to welding fume is associated with adverse effects on worker health. The use of various control measures can reduce levels of exposure and the resulting health effects. However, little is known about the factors that may influence workers' use of control measures in the workplace and their perceived intervention needs. This study aimed to investigate workers' and other stakeholders' views on ways to improve the use of welding fume control measures in Australian workplaces. Methods: We conducted a series of online focus group discussions and individual interviews with participants who have some occupational involvement in welding, whether as workers, employers or industry representatives, union representatives, or regulators. A semi-structured question guide was used, and all discussions and interviews were recorded and transcribed for analysis. Results: Five focus group discussions and five individual interviews were conducted with a total of 21 participants. Three major themes emerged. The first addressed the current awareness of welding fume harms and concern about exposure; the second focussed on the current use of control measures, and barriers and facilitators to their use; and the last centred around intervention needs and the contents of a potential effective intervention. Conclusion Improving the use of control measures to prevent exposure to welding fume requires knowledge around the barriers and facilitators of control, use, and the intervention needs of stakeholders. This study has provided such knowledge, which will facilitate the design and implementation of an intervention to reduce welding fume exposure and ultimately protect the health of workers.

Objective: To explore the association between the consumption of chemical fertilizers and the risk of low birth weight (LBW), to provide references for prevention programs on LBW and to improve the birth outcomes. Methods: Stratified multivariate logistic regression method was used in this study involving 153 preterm LBW infants, 179 term LBW infants and 204 normal control infants that were randomly selected from the birth monitoring data between October 2007 and September 2012 in Pingding county, Shanxi province. Associations between the risk of LBW and maternal exposure to chemical fertilizers during pregnancy were identified. A normal control group was set up to compare results between preterm and term LBW groups. Results: Totally, 18 749 infants were born between 2007 and 2012, with the total incidence rates of LBW as 48.5‰, preterm LBW as 19.4‰, and term LBW as 29.1‰. Concerning the case control study on preterm LBW, after adjustment for confounding factors, the risk of preterm LBW appeared 2.51 (95%CI: 1.05-5.99) times higher in villages with annual consumption of chemical fertilizer ≥100 tons than those villages that using chemical fertilizer less than 50 tons. No significant statistical associations were found between the amounts of household chemical fertilizer consumption and the risks of preterm LBW. Regarding the case control study on term LBW, after adjustment for confounding factors, in villages with ≥100 tons annual consumption of chemical fertilizers, the risk of term LBW was 4.03 (95%CI: 1.63-9.92) times of the risk in villages where the annal use of chemical fertilizers was less than 50 tons. There was no significant association between household consumption of chemical fertilizers and the risk of term LBW. Conclusions: Maternal exposure to chemical fertilizers during pregnancy was associated with the risk of LBW. Our findings suggested that the amount of chemical fertilizer consumption in rural areas seemed also associated with the risks of other adverse pregnancy outcomes. Women should avoid the chance of exposure to chemical fertilizers during pregnancy and the consumption of chemical fertilizers should be carefully managed.

This review addresses the importance of psychoneuroimmunology (PNI) studies in understanding the role of acute and chronic psychological stressors on the immune system and development of coronary artery disease (CAD). Firstly, it illustrates how psychological stressors change endothelial function and lead to chemotaxis. Secondly, acute psychological stressors lead to leukocytosis, increased natural killer cell cytotoxicity and reduced proliferative response to mitogens while chronic psychological stressors may lead to adverse health effects. This will result in changes in cardiovascular function and development of CAD. Thirdly, acute and chronic psychological stressors will increase haemostatic factors and acute phase proteins, possibly leading to thrombus formation and myocardial infarction. The evidence for the effects of acute and chronic psychological stress on the onset and progression of CAD is consistent and convincing. This paper also highlights potential research areas and implications of early detection of immunological changes and cardiovascular risk in people under high psychological stress.

INTRODUCTIONAnti-thyroid antibodies are associated with extra-thyroid diseases such as Graves' ophthalmopathy and Hashimoto's encephalopathy. Some evidence suggests that anti-thyroid antibodies are also associated with depression. Interleukin (IL)-17 appears to play an important role in autoimmune thyroid disease. This study investigated whether specific thyroid autoantibodies and IL-17 distinguished persons with depression from non-depressed controls.

MATERIALS AND METHODSForty-seven adult females with non-psychotic, current major depressive disorder and 80 healthy female controls participated in this study. Thyroid peroxidase antibodies, thyroglobulin antibodies, thyroid-stimulating hormone (TSH) receptor antibodies, free T3 and T4, TSH and IL-17 were measured from the serum. Measurements were repeated to assess test-retest reliability. Receiver operating characteristic (ROC) curves were used to estimate discriminatory values of the measurements. Differences between groups and associations between the clinical and biochemical assessments were analysed.

RESULTSMedian TSH receptor antibody concentration was significantly higher in the depressed than control group (P <0.001). Area under the ROC curve was 0.80 (95% CI, 0.73 to 0.88). Higher TSH receptor antibody titres were associated with greater depression severity scores (r = 0.33, P <0.05). IL-17 levels were not associated with TSH receptor antibody levels or depression severity scores. Thyroid function and other thyroid autoantibodies were not associated with depression severity.

CONCLUSIONTSH receptor antibodies might be a biomarker of immune dysfunction in depression.

Objective: Problematic use of social media (PUSM) may affect sleep quality and self-stigma in people with schizophrenia and consequently reduce their quality of life (QoL). This longitudinal study investigated if sleep quality and self-stigma mediated relationships between PUSM and QoL. Methods: One-hundred-and-ninety-three outpatients with schizophrenia were recruited from a psychiatric center in Taiwan from April 2019 to August 2021 and participated in a longitudinal study at intervals of three months between measurements. QoL was assessed using the World Health Organization Quality of Life Questionnaire Brief Version; sleep quality using the Pittsburgh Sleep Quality Index; self-stigma using the Self-Stigma Scale-Short; and PUSM using the Bergen Social Media Addiction Scale. Via SPSS 20.0, general estimating equation models assessed temporal associations between variables. Via R software, mediating effects of self-stigma and sleep quality were examined through Monte Carlo simulations with 20,000 repetitions. Results: Mean scores of physical, psychological, social and environmental QoL ranged from 11.86 to 13.02. Mean scores of sleep quality and self-stigma were 9.1±4.5 and 2.2±0.8, respectively. Sleep quality and self-stigma were directly related to QoL (p<0.001) and mediated indirect relationships between PUSM and all components of QoL with a range of 95% confidence intervals spanning from -0.0591 to -0.0107 for physical QoL; -0.0564 to -0.0095 for psychological QoL; -0.0292 to -0.0035 for social QoL; and -0.0357 to -0.0052 for environmental QoL. Conclusion Sleep quality and self-stigma mediated relationships between PUSM and QoL in people with schizophrenia. Developing interventions targeting PUSM, sleep, and self-stigma may help improve QoL in people with schizophrenia.

Objective To explore the reaction patterns of impulsiveness and risk-taking decision-making in heroin addicts and their significance.Methods Seventeen heroin addicts(HA group)admitted to Detoxification and Rehabilitation Center of Anhui Province from July 2010 to December 2010 and 18 healthy controls(HC group)recruited at the same period were performed Iowa gambling task(IGT)and Risky-Gains task(RGT),respectively; the different capacities of impulsiveness control and risk-taking decision-making between HA group and HC group were compared.Results As for IGT,decision-making course affected the net scores remarkably in HC group,whereas contrary result was observed in HA group(P＜0.05); no statistical difference between the numbers of low-frequency punishment cards and high-frequency punishment cards which subjects selected was noted in HA group,while statistical difference was observed in HC group(P＜0.05).Furthermore,the difference between the number of low-frequency punishment cards and high-frequency punishment cards in HC group was higher than that in HA group(P＜0.05).In RGT,as compared with risky response rate before punishment,risky response rate after punishment declined notably in HC group,while no significant changes were seen in HA group; risky response rate after reward and after punishment in HA group were significantly higher than those in HC group(P＜0.05).Conclusion As evidence of chronic heroin addicts' behavior,heroin addict exsits impulsiveness and deficit in risk-taking decision-making,which may be one of the causes of generation and maintenance of heroin addiction.

Treatment-induced neuropathy of diabetes (TIND) is an acute painful autonomic small-fiber neuropathy that develops following an abrupt improvement in glycaemia control. Recent reports suggest TIND is a significant problem in tertiary neuropathy clinics. TIND in hospitalized patients with poor initial glycaemia control, that we refer to as nosocomial TIND, has not been well-studied. We describe the demographic, clinical features and indices of glycaemia control in 5 consecutive nosocomial TIND patients. TIND was defined using recently published criteria. Pre-meal capillary blood glucose recordings performed during the period of HbA1c decline was used to calculate glycaemic variability. All the nosocomial TIND patients were hospitalized for prolonged periods for serious medical conditions that warranted good glycaemia control, namely severe sepsis, diabetic ketoacidosis, stroke, heart failure and traumatic head injury. They had raised, double-digit, HbA1c levels at admission that subsequently dropped precipitously with tight in-patient glycaemia control protocols. These patients had multiple, largely asymptomatic, hypoglycaemic episodes. Glycaemic variability also appeared to be high in this cohort. TIND may be a significant cause of morbidity in hospitalized diabetic patients with poor glycaemia control. Not all patients developed both autonomic and painful neuropathies, raising the possibility of forme-fruste TIND
