[Respiratory protection provided by N95 filtering facepiece respirators and disposable medicine masks against airborne bacteria in different working environments].
Objective: To determine the relative protection provided by N95 filtering facepiece respirators (FFR) and disposable medicine masks (DMM) against airborne bacteria in different working environments. Methods: The field study was performed with 12 subjects wearing an N95 filtering facepiece respirator and a disposable medicine mask for 1h, respectively. Airborne microorganisms and bacteria samples from both the external (Ce) and the inner (Ci) surface of N95 FFR and DMM are collected. ⋯ The bacterial filtering proportion of N95 FFR is higher than DMM. These differences were significant in samples tested in summer (P<0.05) , but were not significant in samples tested in winter (P>0.05). Conclusion: Bacterial filtering efficiency of N95 respirator is superior to medicine mask, and this advantage become more obvious in high airborne bacterial concentration levels.

Clinical Trial[Clinical effect of compound monoammonium glycyrrhizinate combined with dandelion in treatment of acute paraquat poisoning].
Objective: To investigate the clinical effect of compound monoammonium glycyrrhizinate combined with dandelion in the treatment of acute paraquat poisoning. Methods: A total of 80 patients with acute paraquat poisoning who were admitted to our hospital were enrolled as study subjects and randomly divided into routine treatment group (38 patients) and traditional Chinese medicine (TCM) group (42 patients). The patients in the TCM group were given compound monoammonium glycyrrhizinate and dandelion in addition to the treatment in the control group. ⋯ Results: On days 3, 7, and 9 of treatment, the routine treatment group had significantly higher serum ALT, TBil, BUN, Cr, and arterial blood Lac than the TCM group. The routine treatment group had significantly lower arterial blood PaO2 than the TCM group, while the TCM group had significantly lower incidence rates of ulceration of oral mucosa, pulmonary fibrosis, and MODS and a significantly lower mortality rate than the routine treatment group (P<0.05). Conclusion: In the treatment of patients with acute paraquat poisoning, compound monoammonium glycyrrhizinate combined with dandelion can effectively improve organ function, reduce the incidence of pulmonary fibrosis and MODS, improve the healing rate of oral ulcer, improve prognosis, and reduce mortality rate.

[A survey of mental health status in armored vehicle crew].
To investigate the mental health status in armored vehicle crew (commanders, gunners, and drivers) , to know the level of mental health in them, and to provide educational intervention. ⋯ A survey should be performed on the mental health status of armored vehicle crew, including obsessive-compulsive symptom, interpersonal sensitivity, depression, and anxiety. Mental health service for the crew should be enhanced to improve their psychological quality.

[Performance evaluation of two N95 filtering-facepiece respirators on decomposition products of sulfur hexafluoride].
To assess the filtration efficiency of two N95 filtering-facepiece respirators (FFRs) for the decomposition products of sulfur hexafluoride (SF6). ⋯ Both the particulate and the acid-proof N95 FFRs met national standards on the particulate filtration efficiency. The acid-proof N95 respirator demonstrates to be more effective in filtering HF and SO2 than the particulate respirator. The filtration efficiency could decrease to an unsafe condition under longer exposure duration, timely replacement of respirator is recommended at the workplace.

Randomized Controlled Trial[Correlation between type D personality and cognitive fusion in 388 employees of state-owned enterprises].
To investigate the correlation between type D personality and cognitive fusion in 388 employees from state-owned enterprises, and to provide a theoretical basis for psychological intervention for type D personality. ⋯ In the employees of state-owned enterprises, cognitive fusion is different between those with type D personality and those without type D personality. In the employees with type D personality, social inhibition and negative affectivity are correlated with cognitive infusion, and negative affectivity plays a role in explaining cognitive fusion.
