ObjectiveTo explore the clinical efficacy of Gouteng prescription in treating the patients with primary hypertension with anxiety disorder due to yang hyperactivity and heat toxin and the impact of the formula on the balance of inflammatory cytokines. MethodA total of 98 patients diagnosed with primary hypertension and anxiety disorder were randomized into control and observation groups. On the basis of conventional western medicine treatment for hypertension， the control group （47 patients） was treated with Shugan Jieyu capsules for 8 weeks， while the treatment group （51 patients） with Gouteng prescription for 8 weeks. The two groups were compared in terms of the blood pressure level， 24-hour blood pressure variability， Hamilton anxiety scale （HAMA） score， Pittsburgh sleep quality index （PSQI） score， quality of life （SF-36 scale） score， traditional Chinese medicine （TCM） syndrome score and efficacy， incidence of adverse reactions， and the levels of interleukin （IL）-1β， IL-6， IL-10， and IL-4 in the serum of peripheral blood. ResultThe final trial was completed with 95 patients， including 46 in the control group and 49 in the observation group. The treatment in both groups lowered the blood pressure and blood pressure variability （P<0.05， P<0.01）. The observation group outperformed the control group in recovering the systolic blood pressure （SBP）， 24-hour mean systolic blood pressure （24 h SBP）， 24-hour systolic blood pressure variability （24 h SBPV）， and 24-hour diastolic blood pressure variability （24 h DBPV） （P<0.05）. After treatment， the HAMA and PSQI scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower HAMA and PSQI scores than the control group （P<0.05）. Compared with those before treatment， the SF-36 scores in both groups increased （P<0.05， P<0.01）. After treatment， the observation group had higher scores of physiological function （PF）， bodily pain （BP）， social function （SF）， role-emotional （RE）， and mental health （MH） indicators than the control group （P<0.05）. After treatment， the TCM syndrome scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower score than the control group （P<0.05）. The total response rate regarding TCM syndrome in the observation group was 85.71% （42/49）， which was higher than that （63.04%， 29/46） in the control group （χ²=6.621， P<0.05）. The treatment in both groups lowered the levels of pro-inflammatory cytokines （IL-1β， IL-6） and elevated the levels of anti-inflammatory cytokines （IL-10， IL-4） （P<0.05， P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.05）. There were no adverse events during the research process. ConclusionGouteng prescription can recover the blood pressure level， reduce blood pressure variability， suppress anxiety state， improve sleep and quality of life， decrease TCM syndrome score， increase total response rate， lower serum IL-1β and IL-6 levels， and elevate serum IL-10 and IL-4 levels in the patients with primary hypertension complicated with anxiety disorder due to yang hyperactivity and heat toxin. It may exert the effects by regulating the balance of pro-inflammatory and anti-inflammatory cytokines.

OBJECTIVE: To investigate the levels of cortisol and inflammatory factors and their influencing factors in patients with occupational noise-induced hearing loss(ONID). METHODS: A total of 106 ONID patients were selected as the ONID group, and 50 healthy participants without noise exposure were selected as the control group by judge sampling method. The levels of salivary cortisol in the two groups were detected by enzyme-linked immunosorbent assay.The serum levels of cortisol, tumor necrosis factor alpha(TNF-α), interleukin-6(IL-6) and C-reactive protein(CRP) in the peripheral blood were detected by electrochemiluminescence assay. Tinnitus Handicap Inventory was used to evaluate the disability levels of tinnitus in ONID patients. RESULTS: The level of salivary cortisol in the morning and in the nighttime, and cortisol, TNF-α, IL-6 in the serum were higher in the ONID group compared with that in the control group(P<0.05). There was no significant difference in the serum level of CRP between these two groups(P>0.05). Spearman correlation analysis results showed that the level of cortisol in the saliva and in the serum was not correlated with TNF-α and IL-6(P>0.05). Analysis of multiple linear regression showed that the levels of serum cortisol and salivary cortisol in the morning in the ONID patients were positively correlated with noise exposure level(P<0.05). The level of TNF-α in the serum was positively correlated with tinnitus score(P<0.05). CONCLUSION: Hyperactivity of hypothalamus-pituitary-adrenal axis and inflammation activation may exist in patients with ONID. The cortisol can be used as a biomarker for the effect of noise-stress.

OBJECTIVE: To investigate the changes of hemorheology and blood lipid index in patients with occupational hand-arm vibration disease(OHAVD). METHODS: A total of 78 patients with OHAVD were selected as the OHAVD group, and 78 workers without hand transmitted vibration exposure were selected as control group by judgment sampling method. The hemorrheology and blood lipid indexes of the two groups were detected. RESULTS: The whole blood viscosities(low-, medium-and high-shear), hematocrit, erythrocyte aggregation index, and abnormal rate of whole blood viscosities(mid-and high-shear) in the OHAVD group were higher in the OHAVD group than that in the control group(P<0.05). The erythrocyte deformability index and erythrocyte electrophoresis index were lower in the OHAVD group than that of the control group(P<0.05). In the vibration-induced white finger(VWF) subgroup of the OHAVD group, the whole blood viscosity(low-, medium-and high-shear), hematocrit were increased(P<0.05), and the abnormal rate of whole blood viscosity(high-shear) was higher(P<0.017) than that of the control group.The whole blood viscosity(medium shear), hematocrit and erythrocyte aggregation index were increased in the non-VWF subgroup than that of the control group(P<0.017). The concentration of low density lipoprotein cholesterol in the OHAVD group and non-VWF subgroup was higher than that in the control group(P<0.05). The whole blood viscosity(low-, medium-and high-shear), hematocrit, erythrocyte deformability index, erythrocyte aggregation index and erythrocyte electrophoresis index were not correlated with the length of service and age in the OHAVD group(P>0.05). CONCLUSION: The changes of hemorheological properties and blood lipids in OHAVD patients may be associated with vibration vascular injury.

OBJECTIVE: To screen the allergens of trichloroethylene-induced occupational medicamentosa-like dermatitis( OMDT) by patch test,and explore methods for OMDT auxiliary diagnosis and trichloroethylene( TCE) allergic population screening. METHODS: A total of 20 subjects diagnosed with OMDT were selected as case group,and 22 nonOMDT healthy workers exposed to TCE≥12 weeks were selected as control group. Different concentrations of TCE and its main metabolites such as chloral hydrate( CH),trichloroethanol( TCOH) and trichloroacetic acid( TCA) were used as allergens in a skin patch test in workers of these two groups. Another 20 new workers exposed to TCE < 12 weeks without OMDT were tested as validation group. They were tested with a patch test at a mass fraction of 15. 00% CH and follow-up observations were performed until 12 weeks of TCE exposure. RESULTS: The patch test of TCE,CH,TCOH and TCA were negative in the control group. In the case group,the patch test positive rate for 50. 00% TCE was 10. 00%,the patch tests were negative in 25. 00%,10. 00% and 5. 00% TCE. The CH patch test positive rate was 100. 00% with the CH mass concentrations of 15. 00%,10. 00% and 5. 00%. The TCOH patch test positive rates were 90. 00%,75. 00% and50. 00%,with the corresponding concentration of 5. 00%,0. 50% and 0. 05%. The TCA patch test positive rates were50. 00% and 0. 00% with the TCA concentrations of 5. 00% and 0. 50% respectively. When the mass concentration was5. 00%,the patch test positive rates in case group from high to low were CH,TCOH,TCA and TCE( P < 0. 01). And the patch test positive rates of CH and TCOH showed no statistical significant difference( P > 0. 05). The patch test positive rate of TCOH increased with increase of TCOH mass concentrations( P < 0. 01). The patch test positive rates for 5. 00%TCA was higher than that of 0. 50% TCA( P < 0. 01). The patch test positive rate in 0. 50% TCOH was higher than that of 0. 50% TCA( P < 0. 01). In the validation group,the patch test of 15. 00% CH was negative,and there was no OMDT case found during the follow-up 12 weeks of TCE exposure. CONCLUSION: The metabolites CH and TCOH of TCE may be the main allergens of OMDT after exposure to TCE. The CH and TCOH patch test can be an auxiliary diagnosis method for OMDT. The CH patch test could be used as a method for screening population allergic to TCE.

OBJECTIVE: To establish the clinical pathway of occupational medicamentosa-like dermatitis due to trichloroethylene(OMDT).METHODS: OMDT was selected as the clinical disease category.The diagnosis and treatment schemes of OMDT were determined and the clinical pathway was developed on the basis of evidence-based medicine,clinical data analysis,and the expert opinion as well as GBZ 185—2006 Diagnostic Criteria of Occupational Medicamentosa-like Dermatitis due to Trichloroethylene.The initial clinical validation was performed.RESULTS: We formulated the clinical pathway of OMDT for medical staffs,including standard hospitalization procedures(including normative use of glucocorticoids),Clinical Path Form,and Informed Consent for Glucocorticoid Therapy.The Clinical Pathway Notification of OMDT for patients or their family members was established.Based on the initial clinical verifications,the clinical pathway was conducive to optimize the medical process,none of the patients suffered from rebounds and complications,and the awareness of OMDT and satisfaction with treatments were improved.CONCLUSION: The clinical pathway for OMDT is scientific and reasonable,which is suitable for use to regulate medical behaviors.

Objective To summarize the experience of nursing six patients who showed pitch-off syndrome when the port was implanted and to analyze the causes of pitch-off syndrome so as to guide the nursing and observation of patients who received port implantation.Methods By observing the patients' symptoms and physical signs based on X-ray reports, pitch-off syndrome was diagnosed. Then correct treatment methods were chosen according to the severity of pitch-off syndrome.Results The six patients with pitch-off syndrome were treated based on their severity. The port-cath was removed in two patients since it cracked. The port-cath was removed in two patients who showed level one pitch-off syndrome after two cycles of chemotherapy. And the port-cath of the remaining two patients was also removed to prevent it from cracking since their level one pitch-off worsened to level three.Conclusions Pitch-off syndrome is the most dangerous complication caused by port implantation. Nursing staff should promptly assess and identify the risks of pitch-off syndrome. The port-cath should be used with great caution when the patients suffer from pitch-off syndrome but badly need venous access. In the event of in vivo cath cracks, nursing staff should work together with doctors to remove the port immediately. Pitch-off syndrome prevention is an important measure to reduce cath cracks.

Objective To assess the value of ultrasound elastography (UE) in the differential diagnosis of benign and ma‐lignant breast masses.Methods Clinical data of 180 female patients with breast masses were collected. A total of 180 masses in these patients were detected by ultrasound (US) and UE to primarily identify the benign or malignant masses before surgery. The diagnostic coincidence rate and values of ROC curve were compared based on the postoperative pathologic results between the two diagnosis methods.Results Forty‐eight benign masses and 127 malignant masses were correctly diagnosed by UE ,and 38 benign masses and 112 malignant masses by US. The sensitivity ,specificity ,accuracy ,positive predictive value and negative predictive value were higher in UE group than in US group ,and there were significant statistical differences (P<0.05 for all). Furthermore ,the value of area under the ROC curve (AUC) in UE group was 0.926 ,significantly higher than that in US group (0.899) (Z=2.8 ,P<0.05).Conclusion UE has the advantages of high sensitivity ,specificity and accuracy in differential di‐agnosis of the nature of breast masses. In terms of some disadvantages of UE ,UE should be combined with US in the diagnosis of benign and malignant breast diseases.
