Objective To explore the anxiety and depression in caregivers of patients in persist vegetative state and minimally conscious state, and discuss the related factors. Methods From January, 2010 to December, 2014, 60 caregivers of 60 patients in persist vegetative state and minimally conscious state were assessed with Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS). The sex, ed-ucation level, relation to the patients and family income of the caregivers, and the age of the patients and number of the families of the pa-tients were recorded, and analyzed with Logistic regression. Results 55％caregivers were found in anxiety, and 48.4％in depression. The fe-male caregivers (OR>6.870, P<0.05), the number of the family of the patients (OR<0.233, P<0.05) and age of the patients (OR<0.294, P<0.05) were independent factors associated with anxiety and depression. Conclusion The caregivers of patients in persist vegetative state and minimally conscious state are troubled in anxiety and depression, especially the female, while age and the number of the families of patient may be important factors for it.

[ABSTRACT]OBJECTIVETo explore the efficacy and safety of localization for parathyroid glands with intravenous low dosage of methylene blue in thyroidectomy. METHODSWe retrospectively reviewed the clinical data of 41 patients who suffered from thyroid papillary carcinoma between Aug, 2014 and Jan, 2015 (9 males and 32 females, with a median age of 46 years). Thirty eight patients underwent primary thyroidectomy and 3 patients underwent second operation. A variety of thyroidectomy was performed in all patients, and who also underwent intravenous (3-4) mg/kg methylene blue in operation. RESULTSEighty four parathyroid glands were stained. Among 39 patients who's parathyroid glands were stained, the mean dyeing time was (31.27±9.41) min. Dyeing rates and dyeing time were not significantly different between 3 mg/kg group and 4 mg/kg group (t=0.24 and 0.20, all P>0.05). None of patients had the hypoparathyroidism problem such as peri-oral numbness, tingling, muscle aches and spasms. According to postoperative monitoring of parathyroid hormone, all of patients had no permanent hypofunction of the parathyroid gland. Neurotoxic effects and other serious side effects were not observed in all patients. CONCLUSIONIntravenous low-dose methylene blue in thyroidectomy is a safe, easy, and effective technique that facilitates rapid identification of parathyroid gland.

BACKGROUND: Cardiopulmonary resuscitation (CPR) is a kind of emergency treatment for cardiopulmonary arrest, and chest compression is the most important and necessary part of CPR. The American Heart Association published the new Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care in 2010 and demanded for better performance of chest compression practice, especially in compression depth and rate. The current study was to explore the relationship of quality indexes of chest compression and to identify the key points in chest compression training and practice.METHODS: Totally 219 healthcare workers accepted chest compression training by using Laerdal ACLS advanced life support resuscitation model. The quality indexes of chest compression, including compression hands placement, compression rate, compression depth, and chest wall recoil as well as self-reported fatigue time were monitored by the Laerdal Computer Skills and Reporting System.RESULTS: The quality of chest compression was related to the gender of the compressor. The indexes in males, including self-reported fatigue time, the accuracy of compression depth and the compression rate, the accuracy of compression rate, were higher than those in females. However, the accuracy of chest recoil was higher in females than in males. The quality indexes of chest compression were correlated with each other. The self-reported fatigue time was related to all the indexes except the compression rate.CONCLUSION: It is necessary to offer CPR training courses regularly. In clinical practice, it might be better to change the practitioner before fatigue, especially for females or weak practitioners. In training projects, more attention should be paid to the control of compression rate, in order to delay the fatigue, guarantee enough compression depth and improve the quality of chest compression.
